DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] In this embodiment, refer to Figure 1-Figure 10 A clamp processing line specifically implemented therein includes a base 1 and a conveying device 2. A leveling device 3, a punching device 4, a heat shrinkable tube device 5 and a bending device 6 are sequentially arranged on the base 1. The heat shrinkable tube device 5 includes an opening piece 51, a cutting piece 52, a heat shrinkable block 53, a clamping claw 54 and a feeding assembly 55. The opening piece 51 and the heat shrinkable block 53 are slidably mounted on the upper end of the base 1, the cutting piece 52 is fixedly mounted on the base 1, the clamping claw 54 is arranged on the upper end of the base 1 through a moving assembly 56, the feeding assembly 55 is arranged on one side of the base 1, the base 1 is provided with a fixed block 11 cooperating with the heat shrinkable block 53, and the base 1 is respectively provided with a driving piece 12 cooperating with the opening piece 51 and the heat shrinkable block 53.

[0036] Through the cooperation of the conveying device 2, the leveling device 3, the punching device 4, the heat shrink tube device 5 and the bending device 6, a fully automated processing flow of the clamp from raw material input to finished product output is realized. This greatly improves production efficiency and reduces labor costs. In this embodiment, two groups of heat shrink tube devices 5 are provided, and the two groups of heat shrink tube devices 5 are sequentially arranged on the base 1 along the first direction. Each group of heat shrink tube devices 5 can independently perform heat shrink tube operations, so that one processing can simultaneously complete the set processing of two sections of heat shrink tubes, thereby improving processing efficiency.

[0037] The feeding assembly 55 includes a rotating disk 551 and a driving motor 552. The rotating disk 551 is rotatably installed on one side of the base 1 by the driving motor 552. A heat shrink tube is installed on the rotating disk 551. The heat shrink tube is transported to the assembly line by the cooperation between the rotating disk 551 and the conveying device 2. When the heat shrink tube reaches a predetermined length, the clamping claw 54 is clamped by the moving assembly 56, and the heat shrink tube is cut by the cutting member 52. Subsequently, the clamping claw 54 is driven by the moving assembly 56 to clamp the cut heat shrink tube and move it to the opening member 51. The opening member 51 slides through the driving member 12, inserts one end of the heat shrink tube and stretches it open, and then the coil is passed through the stretched heat shrink tube by the conveying device 2. When the heat shrink tube is located at the predetermined position of the coil, the opening member 51 releases the heat shrink tube and slides backward, so that the heat shrink tube is sleeved on the outside of the coil. The heat shrink block 53 is pushed by the driving member 12 to shrink the heat shrink tube so that it is fixed at a designated position on the coil, thereby completing the installation of the heat shrink tube.

[0038] The moving assembly 56 includes a fixing frame 561 and a fixing plate 562. The fixing frame 561 is fixedly installed on the base 1 by bolts. The fixing plate 562 is slidably installed on the fixing frame 561 by a guide rod 563. A fixing locking block 564 cooperating with the guide rod 563 is provided on one side of the fixing plate 562. A slidable connecting plate 565 is provided on the fixing plate 562. A piston cylinder 566 cooperating with the connecting plate 565 is provided at one end of the fixing plate 562. The clamping claw 54 is fixedly installed on the connecting plate 565. When in use, the position of the clamping claw 54 is adjusted by sliding the fixing plate 562. When adjusted to an appropriate position, the fixing plate 562 is locked by the fixing locking block 564, and then the connecting plate 565 is pushed to slide by the piston cylinder 566, thereby driving the clamping claw 54 to clamp or release the heat shrink tube.

[0039] The opening member 51 includes an opening cylinder 511 and two clamps 512 symmetrically arranged at the output end of the opening cylinder 511. The two clamps 512 move or rotate in opposite directions through the opening cylinder 511. The clamps 512 are driven by the opening cylinder 511 to open and close. When the clamps 512 open and close, they can open or release one end of the heat shrink tube, thereby facilitating the alignment and assembly of the heat shrink tube and the coil. The mating surface of the clamp 512 and the heat shrink tube is provided with anti-slip teeth to ensure that the heat shrink tube will not slip when clamped, thereby improving the clamping stability.

[0040] Suction cups 513 are symmetrically arranged on both sides of the opening member 51. The suction cups 513 are slidably mounted on the base 1 through a telescopic cylinder 514. The suction cups 513 are fixedly connected to the piston rod of the telescopic cylinder 514. When the telescopic cylinder 514 is working, the piston rod pushes the suction cups 513 to slide. The suction cups 513 realize the opening and closing action through the telescopic cylinder 514, thereby opening the heat shrink tube so that the chuck 512 can be smoothly inserted into the heat shrink tube. After the chuck 512 is inserted into the heat shrink tube, the suction cups 513 release the heat shrink tube and return to their original position. At this time, the chuck 512 continues to open the heat shrink tube to ensure that the heat shrink tube can be completely sheathed on the coil. The setting of the suction cups 513 not only facilitates the opening and sheathing of the heat shrink tube, but also improves the accuracy and efficiency of the installation of the heat shrink tube. The operation of the entire heat shrink sleeve device 5 is made smoother and more automated.

[0041] The cutting member 52 includes a pair of scissors 521 and a driving cylinder 522 for driving the scissors 521 to perform a cutting action. One end of the scissors 521 is provided with a fixed claw 523 that cooperates with the conveying device 2. When in use, the scissors 521 are pushed by the driving cylinder 522 to perform a cutting action. The fixed claw 523 is used to cooperate with the conveying device 2 to keep the heat shrink tube stable during the cutting process and prevent the heat shrink tube from shifting or sliding when cutting. A certain gap is left between the fixed claw 523 and the scissors 521, so that the heat shrink tube has a certain length after being cut by the scissors 521, ensuring that the conveying device 2 can smoothly grab the heat shrink tube for subsequent processing.

[0042] The conveying device 2 includes a feeding frame 21, a guide roller group 22, and a plurality of material-collecting claws 23 for cooperating with the heat shrink tubing device 5 and the bending device 6. The feeding frame 21 is arranged at one end of the base 1. A rotatable feeding disc 211 is arranged on the feeding frame 21. The guide roller group 22 is rotatably mounted on the base 1. The base 1 is provided with a linear module 17 that slidably cooperates with the material-collecting claws 23. A power element that rotatably cooperates with the guide roller group 22 is arranged in the base 1. Through the cooperation between the feeding disc 211 and the guide roller group 22, the coil is transported from the feeding disc 211 to the assembly line, and as the guide roller group 22 rolls, the coil moves along a predetermined path. The linear module 17 pushes the material-collecting claw 23 to slide along the first direction.

[0043] In the heat shrink tubing device 5, the material picking claw 23 is slid by the linear module 17 to grab the heat shrink tube between the scissors 521 and the fixed claw 523. Then, the fixed claw 523 releases the heat shrink tube and slides the material picking claw 23 by the linear module 17 to pull the heat shrink tube. When the heat shrink tube is pulled to a predetermined length, the material clamping claw 54 and the fixed claw 523 are driven to clamp the heat shrink tube, and the heat shrink tube is cut by the scissors 521. Then, the material clamping claw 54 is pushed by the moving component 56 to send the heat shrink tube on the material clamping claw 54 to the designated position to cooperate with the opening member 51 so that the coiled material can pass through. In the bending device 6, the material picking claw 23 is used to clamp the coiled material with the heat shrink tube, and pull it to the bending head 63 for bending operation, thereby completing the bending process of the clamp.

[0044] The leveling device 3 includes a rotating frame 31, a straightening plate 32 and a plurality of rolling rollers 33. The rotating frame 31 is arranged at the upper end of the base 1. The straightening plate 32 is rotatably mounted on the rotating frame 31. The plurality of rolling rollers 33 are divided into two rows and are evenly arranged on the base 1 along the first direction. The rolling rollers 33 are meshed and connected through a gear set 34. The base 1 is provided with a rotating motor 13 that cooperates with the gear set 34. The rotating frame 31 is fixedly mounted on the base 1 by bolts. Both ends of the straightening plate 32 are provided with rotating shafts. The straightening plate 32 is rotatably mounted on the rotating frame 31 through the rotating shafts. Adjustment holes are provided at both ends of the straightening plate 32. The rolling rollers 33 are rotatably mounted on the base 1 through bearings. One end of the rolling rollers 33 is connected to the gear set 34. When in use, the coil is passed through the straightening hole through the straightening plate 32 and inserted between the two rows of rolling rollers 33, and the two rows of fixed rollers are rotated in opposite directions through the cooperation of the rotating motor 13 and the gear set 34, driving the coil to move along a predetermined path, and the straightening plate 32 and the rolling rollers 33 are used to level the coil to keep it flat for subsequent processing operations.

[0045] A return spring 35 is provided at one end of the rolling roller 33. During the movement of the coil, the return spring 35 can ensure that the two rows of rolling rollers 33 always maintain a close fit. In this way, the return spring 35 applies a continuous and uniform leveling pressure to the coil, thereby improving the leveling effect of the coil and meeting the high-precision requirements during the coil processing.

[0046] The blanking device 4 includes a movable die 41 and a fixed die 42. The movable die 41 and the fixed die 42 are respectively provided with stamping dies 43 that match each other. The fixed die 42 is fixedly mounted on the base 1, and the movable die 41 is slidably mounted on the base 1. One side of the base 1 is provided with an output member 14 that is connected and matched with the movable die 41. Through the cooperation of the output member 14 and the movable die 41, the movable die 41 and the stamping die 43 on the fixed die 42 cooperate with each other to complete the blanking process of the coil. The blanking die can be replaced according to the clamp to complete complex processing such as buckles, concave and convex points, fillets and cutting. Make the shape, size and function of the clamp more diversified to meet the needs of different users. A discharge port is provided on the fixed die 42 to facilitate the discharge of waste after blanking to avoid waste accumulation affecting the subsequent processing flow. Thereby ensuring the processing efficiency of the entire blanking device 4.

[0047] In this embodiment, there are two sets of bending devices 6, and the two sets of bending devices 6 are symmetrically arranged at one end of the base 1. The arrangement of the two sets of bending devices 6 enables the coil to be bent twice at the same time, thereby improving the processing efficiency of the clamp.

[0048] The bending device 6 includes a sliding frame 61, a sliding plate 62 and a bending head 63. The sliding frame 61 is slidably mounted on one end of the base 1, the sliding plate 62 is slidably mounted on the sliding frame 61, and the bending head 63 is rotatably mounted on one end of the sliding frame 61. The base 1 and the sliding frame 61 are both provided with a linear rail 64 and a rack 65. The sliding frame 61 and the sliding plate 62 are respectively provided with a slider 66 and a driving gear 67 that cooperate with the linear rail 64 and the rack 65. One end of the sliding frame 61 and the sliding plate 62 is provided with a gear motor 68 that cooperates with the driving gear 67. The bending head 63 is mounted on one end of the sliding plate 62 through a servo motor 70, and the servo motor 70 drives the bending head 63 to rotate, thereby realizing the bending operation of the coil.

[0049] The base 1 is also provided with a positioning claw 15 that cooperates with the bending head 63, and the sliding frame 61 is provided with a pressing cylinder 69 that cooperates with the positioning claw 15. Through the cooperation between the positioning claw 15 and the pressing cylinder 69, the coil is accurately positioned and pressed, avoiding the coil from deflecting or sliding during the bending process, thereby ensuring the accuracy and precision of the bending. The positioning claw 15 is driven by the reciprocating cylinder 16 and is telescopically installed on the base 1. When the coil moves to a predetermined position, the reciprocating cylinder 16 pushes the positioning claw 15 to extend to position the coil, and then the pressing cylinder 69 presses the coil to ensure that the coil remains stable during the bending process. Subsequently, the sliding frame 61 and the sliding plate 62 are driven by the gear motor 68 to slide along the linear rail 64, so that the bending head 63 moves to the bending point of the coil. At this time, the bending head 63 is driven by the servo motor 70 to rotate and perform a bending operation on the coil. Thus, the initial forming of the clamp is formed.

[0050] A production process for a clamp, applicable to the above clamp processing line, comprises the following steps:

[0051] Step 1, conveying the coil to the leveling device 3 for leveling;

[0052] Step 2: open one end of the heat shrink tube through the opening piece 51, pass the coil into the heat shrink tube, and then shrink and fix the heat shrink tube on the coil by cooperating with the fixing block 11 through the heat shrink block 53;

[0053] Step 3: drive the punching device 4 to cut the coil and convey the coil to the bending device 6 for bending.

[0054] Step 4, welding or joining the head and tail ends of the coil to form a clamp;

[0055] Furthermore, the step 1 also includes: conveying the coil to the punching device 4 for punching.

[0056] Furthermore, the method further includes: step 5, heating the heat shrinkable tube to shrink the heat shrinkable tube and make it closely adhere to the surface of the clamp.

[0057] The beneficial effects of the present invention are as follows: by adding a heat shrink tubing device 5 to the automated assembly line, the sleeve connection and shrinkage of the heat shrink tubing can be automatically completed without manual operation during the production process of the clamp, thereby improving production efficiency and reducing production costs while also reducing errors caused by manual operation, thereby improving the quality of the finished clamp.
