Moreover, under the clamping action of the clamping rod 29, the display cabinet back plate 34 can be in a suspended state, which is convenient for the staff to disassemble the display cabinet center plate 35 and the display cabinet back plate 34.
[0030] A matching plate 21 is provided at one end of the movable plate 6 close to the cylinder 3, and the output end of the cylinder 3 is connected to the matching plate 21. Under the action of the matching plate 21, the output end of the cylinder 3 can drive the movable plate 6 to perform translational movement. The translational lifting mechanism 33 includes a guide plate 4, and the guide plate 4 is fixedly installed above the guide groove 10. A path groove 5 is provided on the surface of the guide plate 4, and the upper roller 9 is movably installed in the path groove 5. When the cylinder 3 pushes the movable plate 6 to translate forward, the upper roller 9 will move along the path of the path groove 5, and the lower roller 9 will move along the path of the guide groove 10.

[0032] The centering clamping mechanism 12 includes four slides 15, which are all arranged above the lifting plate 7, and the four slides 15 are respectively located in four directions of the lifting plate 7. Two slide grooves 17 are arranged on the surface of the lifting plate 7 and below the slide 15. Two vertical plates 16 are symmetrically installed at the bottom of the slide 15. The two vertical plates 16 are respectively slidably installed in the two slide grooves 17. The bottom of the two vertical plates 16 is installed with a connecting rod 13 through a rotating shaft. The four end faces of the center block 11 are all provided with a protrusion 14, and the protrusion 14 is parallel to the slide 15. The bottom of the connecting rod 13 is connected to the protrusion 14 through a rotating shaft. The surface of the slide 15 is installed with a The clamping plate 19, the protrusion 14 and the vertical plate 16 are connected by the connecting rod 13. As the lifting plate 7 is continuously raised, the connecting rod 13 will gradually become vertical. At this time, the slide 15 will slide toward the center of the lifting plate 7. Under the action of the clamping plate 19, the display cabinet back plate 34 can be clamped in a centering manner to ensure that the display cabinet back plate 34 can always be positioned at the center of the lifting plate 7, which is convenient for the cooperation between the display cabinet center plate 35 and the display cabinet back plate 34. A convex strip 18 is arranged between the two slide grooves 17, and a concave strip corresponding to the convex strip 18 is arranged at the bottom of the slide 15.

The matching block is slidably arranged in the V-shaped groove 37. When the threaded rod 25 controls the position of the movable block 24 to change, the position of the matching block in the V-shaped groove 37 will also change. At this time, under the action of the L-shaped strip 28 and the limiting groove 26, the cross bar 27 will only move in the direction of the limiting groove 26, so that when the movable block 24 moves, the spacing between the two cross bars 27 will change, thereby achieving the clamping of the display cabinet center plate 35. Finally, after the display cabinet center plate 35 and the display cabinet back plate 34 are welded, when the cylinder 3 drives the movable plate 6 to be recovered, the position of the lifting plate 7 moves down, and the clamping force of the clamping plate 19 on the display cabinet back plate 34 is reduced. At the same time, under the clamping action of the clamping rod 29, the display cabinet back plate 34 can be in a suspended state, which is convenient for the staff to disassemble the display cabinet center plate 35 and the display cabinet back plate 34.
[0035] A display cabinet back panel 34 is placed horizontally on the surface of the lifting plate 7, and a display cabinet center panel 35 is clamped and installed between the two clamping rods 29.

[0037] Working principle: first, place the display cabinet back plate 34 directly on the surface of the cross support 20. When the cylinder 3 pushes the movable plate 6 to move forward, the roller 9 at the top will move along the path of the path groove 5, and the roller 9 at the bottom will move along the path of the guide groove 10. When the roller 9 at the top moves to the front end of the path groove 5, under the thrust of the cylinder 3, the roller 9 at the top will gradually move upward along the convex groove, and the lifting rod 8 will gradually tend to a vertical state, thereby achieving the lifting effect of the lifting plate 7. Then, as the lifting plate 7 is continuously raised, the connecting rod 13 will gradually become vertical. At this time, the slide 15 will slide toward the center of the lifting plate 7. Under the action of the clamping plate 19, the display cabinet back plate 34 can be clamped in a centering manner to ensure that the display cabinet back plate 34 can always be positioned at the center of the lifting plate 7. The display cabinet center plate 35 is convenient for matching with the display cabinet back plate 34. Then, under the action of the preparatory clamping mechanism 36, the clamping rod 29 can fix the display cabinet center plate 35, so that the display cabinet center plate 35 and the display cabinet back plate 34 are perpendicular to each other, which is convenient for welding the T-joint in the display cabinet. Manual support is not required by the staff, which effectively improves the positioning accuracy and the yield rate, and can reduce labor costs and improve production safety. Finally, after the display cabinet center plate 35 and the display cabinet back plate 34 are welded, when the cylinder 3 drives the moving plate 6 to be recovered, the position of the lifting plate 7 moves down, and the clamping force of the clamping plate 19 on the display cabinet back plate 34 is reduced. At the same time, under the clamping action of the clamping rod 29, the display cabinet back plate 34 can be in a suspended state, which is convenient for the staff to disassemble the display cabinet center plate 35 and the display cabinet back plate 34.
