[0034] Figures 1-4 A transfer device for plastic products provided in this embodiment of the present invention includes:

[0035] Transfer grippers, including:

[0036] Connecting plate 1;

[0037] Two vertical baffles 2 are arranged along the front-to-back direction and spaced apart at the lower end of the connecting plate 1, forming a limiting cavity between them;

[0038] The limiting plate 3 is horizontally disposed in the limiting cavity and is connected to the two vertical baffles 2 respectively;

[0039] Two clamping plates 4 are vertically arranged in the left-right direction and are located on the front and rear sides of the limiting plate 3, respectively;

[0040] A driving mechanism is disposed at the lower end of the connecting plate 1 and connected to the upper ends of the two clamping plates 4 to drive the two clamping plates 4 to move closer or further away from each other. The lower ends of the clamping plates 4 extend downward to below the limiting cavity.

[0041] The robotic arm is connected to the connecting plate 1;

[0042] The operating table 8 has a strip-shaped through groove 14 at its upper end along the front-back direction, and the bottom wall of the strip-shaped through groove 14 has an installation groove 9.

[0043] A lifting mechanism is provided in the mounting slot 9.

[0044] Specifically,

[0045] In this embodiment, taking plastic cup lids as an example, the quantitatively separated plastic cup lids are stacked in a row and fed into the strip groove 14 on the operating table 8 in the front-to-back direction in the form of a plastic cup lid row. They are then pushed forward onto the lifting mechanism. Figure 3 As shown, at this time, the robotic arm moves the transfer gripper above the operating table 8, and the limiting cavity formed between the two vertical baffles 2 aligns with the strip-shaped through groove 14, forming the loading position. Then, the lifting mechanism lifts the plastic cup lids upwards, and the plastic cup lids are positioned between the two clamping plates 4. Figure 4 As shown, the plastic cup lid enters the limiting cavity until its upper end contacts the limiting plate 3, at which point the lifting mechanism stops lifting. Then, the drive mechanism moves the two clamping plates 4 closer together to clamp the plastic cup lid between them, and finally, the robotic arm drives the transfer gripper to move it to the packaging equipment.

[0046] Preferably, in another embodiment of the present invention, the driving mechanism includes:

[0047] Two sets of linear drive components are disposed between the two clamping plates 4 and connected to the two clamping plates 4 respectively, to drive the clamping plates 4 to move in the back-and-forth direction. The linear drive components include:

[0048] The horizontal telescopic cylinder 5 has its cylinder body located at the lower end of the connecting plate 1, and its push rod is arranged in the front-to-back direction.

[0049] The slider 6 has a guide rail 7 at the lower end of the connecting plate 1 along the front-back direction. The upper end of the slider 6 is slidably connected to the guide rail 7. One end of the slider 6 is connected to the push rod of the horizontal telescopic cylinder 5, and the other end is connected to the corresponding clamping plate 4.

[0050] In this embodiment, the horizontal telescopic cylinder 5 drives the slider 6 to slide along the guide rail 7 in the front-back direction, thereby moving the clamping plate 4 back and forth. By setting the slider 6, the movement of the clamping plate 4 can be made more stable.

[0051] Preferably, in another embodiment of the present invention, the lifting mechanism includes:

[0052] The lifting plate 10 is horizontally positioned within the mounting groove 9;

[0053] At least two lifting telescopic cylinders 11, the cylinder bodies of which are mounted on the operating table 8 via brackets, and the push rods of the lifting telescopic cylinders 11 are set upward and connected to the lifting plate 10;

[0054] The limiting rod 12 is vertically arranged at the front end of the lifting plate 10, and the clamping plate 4 located in front of it has a notch corresponding to the limiting rod 12.

[0055] In this embodiment, in the initial state, such as Figure 3 As shown, the lifting plate 10 is located in the mounting groove 9, with its upper end flush with the upper end of the strip groove 14. Plastic cup lids are arranged in the strip groove 14 and move forward onto the lifting plate 10. After the foremost plastic cup lid contacts the limiting rod 12, multiple plastic cup lids remain on the lifting plate 10. Then, the lifting cylinders extend synchronously, lifting the lifting plate 10 upwards. Figure 4 As shown, this causes the plastic cup lid on the lifting plate 10 to move to the loading position of the transfer mechanism, where it is then transported away. After the plastic cup lid is transported away, the lifting cylinder retracts synchronously, and the lifting plate 10 returns to its initial position.

[0056] Preferably, in another embodiment of the present invention, the lifting mechanism further includes:

[0057] Multiple support blocks 13 are spaced apart on the inner wall of the mounting groove 9. When the lifting plate 10 is housed in the mounting groove 9, it rests on the support blocks 13.

[0058] In this embodiment, the lifting plate 10 is supported by the support block 13, which reduces the force exerted by the lifting plate 10 on the horizontal telescopic cylinder 5 when it is located in the mounting groove 9.
