Bar code scanning device for cold storage in blood preservation

The invention discloses a bar code scanning device for cold storage in blood preservation. The technical solution to the problem in prior art is that the barcode-attached blood cartridges placed in the cold storage cabinet can be automatically and quickly scanned one by one, therefore, reducing manpower cost and improving work efficiency. The scanning device of the invention further comprises a rectangle frame with a beam on the front side. A rail is mounted at the front end of the beam in the longitudinal direction of the beam; the rail is provided with a slide block; a longitudinal bar is arranged on the upper end of the rectangular frame; a scanning head is arranged on the rear lower end surface of the longitudinal bar; the scanning eye of the scanning head is arranged facing downwards; the lower end of the beam is provided with a transmission mechanism which is capable of driving the longitudinal bar to move in lateral translation; the longitudinal bar is connected with the transmission mechanism through a connecting block and a transverse T-shaped fixing plate; the transverse T-shaped fixing plate is a provided with a control board in connection with the scanning head. Compared to the prior art, the device of the invention can automatically enter the bar code information automatically, reduce labor cost and improve work efficiency.
