[0038] ​Through the combination structure of the rotating machining table 11, the multi-station support 12, the conveying device 13, the feeding device 14 and the pressing device 15, the worker can place the H-shaped elastic sheet 49 on the first conveying belt 16 of the conveying device 13, drive the first conveying belt 16 to rotate by the main motor 18 and the auxiliary motor 19 to drive the rotating roller 17 to realize the automatic conveying of the H-shaped elastic sheet 49, and then realize the feeding and pressing clamping of the screw sleeve block 52 by the rotating machining table 11, the feeding device 14 and the pressing device 15 in turn, so as to realize the automatic assembly process of the H-shaped elastic sheet 49 and the screw sleeve block 52 and reduce manual intervention.

[0039] The rotating shafts 22 are symmetrically installed on the side walls of the conveying device 13, both of which are parallel to the output shaft of the main motor 18, and the circumferential surfaces of the rotating shafts 22 and the output shaft of the main motor 18 are provided with pulleys 23, the second conveying belt 24 is wound between the pulleys 23, the eccentric wheels 25 are fixedly installed on the side walls of the rotating shafts 22, the limit grooves 26 are formed in the eccentric wheels 25, the sliding blocks 27 are slidably installed in the limit grooves 26, the T-shaped transmission rods 28 are fixedly installed between the sliding blocks 27, the piston cylinders 29 are symmetrically arranged in the conveying device 13, the U-shaped strips 31 are fixedly installed at the lower ends of the piston cylinders 29, the T-shaped transmission rods 28 are slidably installed in the U-shaped strips 31, the inner cavities 32 are arranged in the piston cylinders 29, the sliding grooves 33 are symmetrically and penetratively arranged in the inner cavities 32, the sealing protruding blocks 34 are sealingly and slidably installed in the sliding grooves 33, the wedge-shaped blocks 35 are fixedly installed at the upper ends of the sealing protruding blocks 34, and the piston rods 36 are slidably installed in the inner cavities 32 and fixedly installed with the T-shaped transmission rods 28;

[0040] When the T-shaped transmission rods 28 move upwards, the piston rods 36 move upwards, the piston rods 36 extrude the hydraulic oil in the inner cavities 32 to make the sealing protruding blocks 34 move outward in the sliding grooves 33, and when the H-shaped elastic sheet 49 is conveyed to the bottom of the first conveying belt 16, it is accurately dropped on the wedge-shaped blocks 35 of the expanded sealing protruding blocks 34, the automatic expansion and contraction of the sealing protruding blocks 34 is realized by hydraulic drive, the smooth transition of the H-shaped elastic sheet 49 from the conveying state to the receiving state is realized without manual intervention, and the subsequent spraying of the adhesive is facilitated;

[0041] Through the cooperation of the first conveying belt 16 and the U-shaped plate group 21, the two sides of the H-shaped elastic sheet 49 abut against the outer wall of the first conveying belt 16 to achieve preliminary limiting, avoiding deviation during conveying. At the same time, the main motor 18 drives the rotating shaft 22, the eccentric wheel 25 to rotate through the belt pulley 23 and the second conveying belt 24, so that the T-shaped transmission rod 28 moves vertically reciprocatingly under the limiting of the U-shaped strip 31, and then drives the piston rod 36 to move in the inner cavity 32 of the piston cylinder 29. The hydraulic oil pushes the sealing protruding block 34 to slide in the sliding groove 33 and expand. When the H-shaped elastic sheet 49 is conveyed to the bottom of the first conveying belt 16, it accurately falls on the wedge-shaped block 35 of the sealing protruding block 34, realizing the stable fixing of the H-shaped elastic sheet 49, which is beneficial to subsequent operation.

[0042] The synchronous rod 37 is fixedly installed at the four corners of the upper end of the piston rod 36, the rod body of the synchronous rod 37 extends out of the upper side of the piston cylinder 29 and is sealingly and slidably installed with the piston cylinder 29, and the upper end of the synchronous rod 37 is fixedly installed with the rectangular plate 38. The top of the wedge-shaped block 35 is parallel to the top of the piston cylinder 29. The upper end of the piston cylinder 29 is provided with a strip-shaped box body 39, which is located on the inner side of the U-shaped plate group 21. The surface of the strip-shaped box body 39 is symmetrically provided with a pressing nozzle unit 41. The pressing nozzle unit 41 comprises a pressing pump head 42, a pressing head 43 and a rectangular nozzle 44. The pressing pump head 42 and the rectangular nozzle 44 are arranged on the surface of the strip-shaped box body 39. The rectangular nozzle 44 is located below the pressing pump head 42. The lower end of the pressing pump head 42 (the pressing nozzle unit 41 is prior art, mainly comprising a pressing pump head 42, a pressing head 43 and a rectangular nozzle 44, a one-way valve, a liquid inlet pipe, a cylinder body, a plunger, a spring. Since it is prior art, only the structure of the cooperation is described) is provided with the pressing head 43. There is a gap between the pressing head 43 and the rectangular plate 38. The upper end of the strip-shaped box body 39 is provided with a conveying pipe 45 (the conveying pipe 45 can convey the external adhesive into the strip-shaped box body 39 for storage);

[0043] By arranging the rectangular strip-shaped box body 39 above the piston cylinder 29 and the U-shaped strip 31 below the piston cylinder 29, the groove 51 of the H-shaped elastic sheet 49 can be located on the outer side of the strip-shaped box body 39 and the U-shaped strip 31 during transfer, ensuring that the H-shaped elastic sheet 49 can be limited during transfer, improving the cooperation accuracy of each process and increasing the transfer stability.

[0044] The gap between the rectangular plate 38 and the pressing head 43 provides time for the H-shaped elastic piece 49 to fall onto the wedge-shaped block 35, and then the rectangular plate 38 extrudes the pressing head 43, so that the pressing pump head 42 sprays the adhesive in the strip-shaped box 39 onto the groove 51 of the H-shaped elastic piece 49 through the rectangular nozzle 44, realizing the pre-bonding treatment of the groove 51. With the continuous rotation of the eccentric wheel 25, the piston rod 36, the sealing protruding block 34, the wedge-shaped block 35 and the pressing head 43 are automatically reset, the H-shaped elastic piece 49 falls into the mold cavity 48 of the mold 47, and the automatic processing is completed.

[0045] The gap between the pressing head 43 and the rectangular plate 38 ensures that the H-shaped elastic piece 49 falls smoothly from the bottom of the first conveying belt 16 and is stably placed on the wedge-shaped block 35 of the sealing protruding block 34, avoiding the premature triggering of the pressing action that prevents the rectangular nozzle 44 from fully spraying the adhesive on the H-shaped elastic piece 49.

[0046] The inside of the conveying device 13 is symmetrically fixedly installed with a fixed block group 46, which is fixedly installed with the piston cylinder 29 and the strip-shaped box 39. The circumferential surface of the rotary processing table 11 is provided with a mold 47, and the mold 47 is provided with a mold cavity 48. The mold cavity 48 is provided with an H-shaped elastic piece 49, and the surface of the H-shaped elastic piece 49 is symmetrically provided with a groove 51. The groove 51 is provided with a screw sleeve block 52. The conveying device 13, the feeding device 14 and the pressing device 15 are matched with the mold 47, the H-shaped elastic piece 49 and the screw sleeve block 52.

[0047] The adhesive sprayed in the groove 51 can enhance the connection between the H-shaped elastic piece 49 and the screw sleeve block 52, providing a good pretreatment basis for the subsequent assembly of the screw sleeve block 52. At the same time, the assembly of the screw sleeve block 52 can realize the structural fixation and functional perfection of the H-shaped elastic piece 49, meeting the assembly requirements of the elastic piece. The whole relies on the rotary processing table 11 for transportation and processing, so that the H-shaped elastic piece 49 can be transported to the feeding device 14 below for screw sleeve block 52 feeding, and then transported to the pressing device 15 below for pressing and clamping, without frequent manual positioning during the whole process, thereby realizing the integrated and automated processing of the H-shaped elastic piece 49 from conveying, pretreatment to assembly, effectively reducing the manual operation steps, improving the processing efficiency and assembly precision, and ensuring the stability of product quality.

[0048] Working principle:

[0049] In the first step, the H-shaped elastic sheet 49 is placed on the opposite U-shaped plate group 21 on the first conveying belt 16 by the industrial robot, and the two sides of the H-shaped elastic sheet 49 abut against the outer wall of the first conveying belt 16 to achieve preliminary positioning. Then, the main motor 18 and the auxiliary motor 19 are started, and the output shaft of the main motor 18 and the auxiliary motor 19 drives the rotating roller 17 to rotate, and the rotating roller 17 drives the first conveying belt 16 to rotate, so as to convey the H-shaped elastic sheet 49 downward. When the industrial robot places the second H-shaped elastic sheet 49 on the first conveying belt 16, a layer of U-shaped plate group 21 should be intentionally left empty to meet the reset requirement of the eccentric wheel 25.

[0050] In the second step, the main motor 18 drives the rotating shaft 22 to rotate through the belt wheel 23 and the second conveying belt 24, and the rotating shaft 22 drives the eccentric wheel 25 to rotate, so that the limiting groove 26 in the eccentric wheel 25 actively slides with the sliding block 27. Because the T-shaped transmission rod 28 is limited in the U-shaped strip 31, the T-shaped transmission rod 28 moves vertically and reciprocally, and the sliding block 27 moves vertically and reciprocally synchronously.

[0051] In the third step, when the T-shaped transmission rod 28 moves upward, the piston rod 36 moves upward, and the piston rod 36 moves upward in the inner cavity 32 and extrudes the hydraulic oil in the inner cavity 32. The hydraulic oil generates pressure on the sealing protruding block 34, and the sealing protruding block 34 moves outward under the sealing sliding action of the sliding groove 33. Therefore, when the H-shaped elastic sheet 49 is conveyed to the bottom of the first conveying belt 16, it will accurately fall on the wedge-shaped block 35 of the sealing protruding block 34 which is unfolded outward.

[0052] In the fourth step, with the continuous movement of the piston rod 36, the synchronous rod 37 and the rectangular plate 38 move upward. Because there is a gap between the rectangular plate 38 and the pressing head 43, the rectangular plate 38 does not immediately extrude the pressing head 43 during the unfolding process of the sealing protruding block 34. This gap provides sufficient time for the H-shaped elastic sheet 49 to fall. Finally, the rectangular plate 38 extrudes the pressing head 43 of the pressing pump head 42, and the pressing head 43 accurately sprays the adhesive in the strip-shaped box 39 to the groove 51 of the H-shaped elastic sheet 49 through the rectangular nozzle 44. Then, with the continuous reciprocating movement of the eccentric wheel 25 and the sliding block 27, the piston rod 36 is reset, and the sealing protruding block 34, the wedge-shaped block 35 and the pressing head 43 are also reset, and the H-shaped elastic sheet 49 falls into the mold cavity 48.

[0053] In the fifth step, the worker opens the rotating machining table 11, and then transfers the mold 47 with the H-shaped elastic piece 49 to the lower part of the feeding device 14 (the feeding device 14 is prior art, mainly composed of a storage assembly, a pushing mechanism and a positioning component, the storage assembly is used for storing the screw sleeve block 52, the pushing mechanism can push the screw sleeve block 52 out of the storage assembly one by one, and the positioning component ensures that the screw sleeve block 52 can accurately fall into the groove 51), and then the feeding device 14 feeds the screw sleeve block 52 into the groove 51; after the feeding is completed, the worker opens the rotating machining table 11 again, and then transfers the mold 47 to the lower part of the pressing device 15, and then the pressing device 15 (the pressing device 15 is prior art, located in the subsequent process position of the feeding device 14, mainly used for pressing and clamping the screw sleeve block 52 fed into the groove 51 on the H-shaped elastic piece 49, mainly composed of a driving assembly and a pressing execution part, the driving assembly provides pressing power, the pressing execution part directly contacts and applies pressure to the screw sleeve block 52 to complete the processing) presses the screw sleeve block 52 into the H-shaped elastic piece 49, and then the worker can use the suction cup clamp to suck away the processed workpiece, thereby completing the processing.
