[0002] Blister trays, as a common packaging material, are widely used in the transportation and storage of electronic components, medical devices, and other industries. With the expansion of production scale, the size and weight of blister trays are gradually increasing. Currently, the industry mainly uses mechanical clamping or manual handling to transfer blister trays to the stacking position. However, because the blister tray is made of soft material, it is easy to deform during the handling process, which affects the accuracy and efficiency of stacking.

[0003] Furthermore, during the stacking of large-sized blister trays, due to the limited number of clamping points during the transfer process, the blister trays themselves undergo a certain degree of deformation. This results in the blister trays failing to accurately match and engage with the lower blister trays, fixtures, etc., during the lowering process, which needs to be improved.

[0074] The implementation principle of an automatic stacking device for blister trays in this application embodiment is as follows: First, the rodless cylinder A9 is activated to adjust the lateral position of the displacement frame 10, and the rodless cylinder C13 is used to adjust the longitudinal position of the push frame 14 until the support frame 3 reaches above the blister tray to be stacked. Then, the vertical height of the support 12 is adjusted by the rodless cylinder B11 so that the support plate 4 is close to the blister tray. The drive motor 61 is started to drive the drive rod 58 to rotate, which causes the transmission spur gear 59 to move the reduction spur gear 60, thereby driving the drive shaft 55 to rotate. With the connection between the drive shaft 55 and the transmission plate 56, as the transmission rod 57 rotates with the transmission plate 56, the adaptive displacement of the transmission rod 57 inside the stand 54 can cause the support shaft 48 to drive the guide plate 49 to rotate until the loading plate 50 reaches above the blister tray to be stacked. The image of the blister tray to be stacked is obtained by the vision sensor 51. After the image is obtained, the drive motor 61 is started to drive the drive rod 58 to rotate in the opposite direction until the loading plate 50 is adjusted to the side of the support plate 4. Then, the drive motor A18 is started to drive the central shaft 16 to rotate. With the two opposing spiral thread sections 17 on the central shaft 16, when the central shaft 16 rotates, it can drive the two displacement seats 19 to move closer or further apart, causing the bearing cylinder 21 to move along the linear guide rod 5, thereby adjusting the lateral position of the vacuum suction cup A25. Then, the drive motor B27 is started to drive the drive shaft 26 to rotate. Since the hollow shaft 28 is connected to the drive shaft 26, under the action of the limiting strip, the hollow shaft 28 can rotate synchronously with the drive shaft 26. With the help of the movement of the push protrusion 65 inside the linkage slot 64, the guide frame 31 is vertically displaced under the limitation of the limiting light rod 30. Since the push rod 32 is connected between the extension ear 33 and the guide frame 31, when the guide frame 31 is vertically adjusted, the push rod 32 can push the displacement rod 22, causing the vacuum suction cup A25 to be longitudinally adjusted until the four vacuum suction cups A25 reach the four corners of the blister tray respectively. Then, the rodless cylinder B11 is activated to cause the support 12 to be vertically adjusted until the vacuum suction cup A25 contacts the blister tray to be stacked. The vacuum generator A24 is activated to create negative pressure at the vacuum suction cup A25, which then picks up the blister tray. Subsequently, the operation of the rodless cylinders A9, B11 and C13 transfers the blister tray to the stacking position. Before lowering the blister pack, the drive motor 61 is activated to adjust the loading plate 50 to below the support plate 4. The vision sensor 51 acquires an image of the stacked blister packs. When there is a positional deviation between the blister pack to be stacked and the stacked blister packs, the push cylinder 44 is activated to push the adjusting seat 45 downwards until the vacuum suction cup B47 contacts the blister pack to be stacked. Then, the vacuum generator B46 creates a negative pressure at the vacuum suction cup B47, thereby allowing the vacuum suction cup B47 to pick up the blister pack. Simultaneously, the vacuum suction cup A25 releases the blister pack. After the vacuum suction cup B47 picks it up, the adjusting motor A35 is activated to drive the spur gear A36 to rotate. The spur gear A36 then... With the transmission rack A37 connected, the spur gear A36 can move along the transmission rack A37 to adjust the lateral position of the assembly frame 34 on the linear guide rod 5. The adjustment motor B41 can be started to make the spur gear B42 move the transmission rack B40, thereby driving the anti-rotation slide rod 39 to adjust under the support of the guide cylinder 38, so as to make a small movement and deformation of the blister tray. When the shape of the blister tray at the vacuum suction cup B47 is basically consistent with the shape of the stacked suction tray below, the drive motor 61 is started to drive the loading plate 50 to flip until the loading plate 50 reaches the side of the bearing plate 4. Then, through the operation of the rodless cylinder B11, it is placed on the stacked blister tray.

[0075] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
