Description

Technical Field

[0001] The utility model relates to the technical field of lamp string processing equipment, in particular to a synchronous clamping, cutting and wire-disconnecting structure. Background Art

[0002] The production process of the finished lamp string mainly includes the front process and the back process. In the front process, the lamp string is wound around the die bar, and the starting point of the winding wire of the lamp string is fixed at a specific position on the die bar. In the back process, the lamp string wound around the die bar is successively cut to disassemble it into several required lengths. After the disassembly is completed, the die bar is transferred back to the front process again, and so on in a cycle.

[0003] In the prior art, the front process has been automated, while in the back process, the die bar wound with the lamp string is still manually placed on the die bar rotating frame, and then each lamp string on the die bar is successively disassembled from the winding starting point by hand, pulled to the required length of the lamp string, and then cut off with scissors and sorted out neatly. This process needs to be repeated many times to disassemble all the lamp strings on the die bar. Therefore, the working-hour efficiency of the front process and the back process is seriously mismatched. The labor intensity of the workers in the back process is large, time-consuming and laborious, and the efficiency is low. And it causes the die bar to stay, seriously affecting the re-investment of the front process of the lamp string, and further affecting the production efficiency of the entire lamp string production line.

[0004] Therefore, there is an urgent need for a synchronous clamping, cutting and wire-disconnecting structure to quickly cut and disassemble the lamp string on the die bar into the required lengths to improve the efficiency of the back process. Summary of the Utility Model

[0005] In view of the above deficiencies in the background art, the utility model provides a synchronous clamping, cutting and wire-disconnecting structure, which solves the technical problem that the low disassembly efficiency of the lamp string on the die bar in the prior art leads to low production efficiency of the lamp string.

[0006] The technical solution of this application is as follows:

[0007] A synchronous clamping, cutting and wire-disconnecting structure includes a clamping component for clamping the lamp string on a rotatable die bar. A cutter component for cutting the lamp string is further arranged between the die bar and the clamping component. The clamping component stretches the lamp string through a moving mechanism.

[0008] Based on the process of winding the lamp string around the die bar, this technical solution utilizes the characteristic that the positions of the lamp strings wound around the die bar are consistent, and adopts synchronous clamping by the clamping component. The clamping position of the clamping component is determined according to the required length of the lamp string to be produced. After the clamping component clamps at a specific position of the lamp string, the cutter component synchronously cuts the corresponding position of the lamp string, and then the moving mechanism is used to pull the lamp string to disassemble it from the die bar, finally realizing the automatic multi-segment and one-time disassembly of the lamp string on the die bar.

[0009] Preferably, the clamping assembly includes several pairs of matching fixed jaws and movable jaws, and the gap between each pair of movable jaws and fixed jaws is adjustable. The number of pairs of movable jaws and fixed jaws depends on the required length of the finished lamp string product, which facilitates the cutting of lamp strings with various lamp distances and the production of lamp string products with various required lengths. The adjustable gap between each pair of movable jaws and fixed jaws facilitates the clamping of lamps of various specifications.

[0010] Preferably, the fixed jaws are connected to the jaw fixing member, and the movable jaws are connected to the cross pull rod. The cross pull rod is slidably connected to the jaw fixing member. When the cross pull rod slides, it drives the movable jaws to slide relative to the fixed jaws, thereby realizing the adjustment of the gap between the movable jaws and the fixed jaws.

[0011] Preferably, the jaw fixing member is further provided with a limit block for stopping the sliding of the cross pull rod. The limit block is used to limit the maximum gap between the movable jaws and the fixed jaws.

[0012] Preferably, the cutting tool assembly includes several cutting tools connected to the substrate, and the cutting tools correspond to the fixed jaws one by one. This facilitates the synchronous shearing of the lamp string by each cutting tool after the lamp string is clamped.

[0013] Preferably, a cutting tool seat is provided on one side of the substrate close to the mold bar. The cutting tool seat is provided with several evenly spaced mounting grooves, and the cutting tools are detachably connected to the cutting tool seat through the mounting grooves. This ensures that the number of cutting tools is adjustable, the position of the cutting tools on the cutting tool seat is adjustable, and thus the distance between two adjacent cutting tools is adjustable.

[0014] Preferably, a liftable wire guide plate is connected between the cutting tool and the mold bar, and the wire guide plate is higher than the cutting tool when it is lifted. When pulling the lamp string, the wire guide plate is lifted to prevent the lamp string from being damaged by hitting the cutting tool due to elastic shaking.

[0015] Preferably, several evenly spaced wire columns are provided on the side of the substrate facing away from the cutting tool, and the wire columns correspond to the cutting tools one by one. The wire columns are used to guide the lamp string when pulling the lamp string.

[0016] Preferably, a double-rod cylinder for adjusting the distance between the cutting tool and the mold bar is provided on the substrate, and a slide rail parallel and spaced from the double-rod cylinder is also provided on the substrate. The double-rod cylinder can drive the cutting tool to slide closer to and away from the mold bar to realize the synchronous shearing of the lamp string and the return of the cutting tool, and the slide rail is used to reduce friction.

[0017] Preferably, the mold bar is rotatably connected to the rotating frame, and the rotating frame is arranged on the mold bar conveying mechanism. The rotating frame can make the mold bar rotate when pulling the lamp string, and the mold bar conveying mechanism is used to continuously convey the mold bar wound with the lamp string to realize the disassembly of the lamp string products on the continuous mold bar.

[0018] Compared with the prior art, the technical solution disclosed by the present utility model has the following beneficial effects:

[0019] Through the cooperation of the clamping component, the cutting tool component, the moving mechanism and the mold bar conveying mechanism, the continuous, efficient and accurate disassembly of the finished mold bar lamp string is realized, thus achieving the rapid return of the mold bar, improving the reuse rate of the mold bar, breaking through the bottleneck process in the lamp string industry field, and then greatly improving the efficiency of the lamp string production line; both the economic benefits and the enterprise benefits are greatly improved.

[0020] The utility model can realize the synchronous clamping, pulling and shearing of various specifications in the lamp string industry, such as 0.26MM, 0.35MM, 0.38MM, and various lamp distances, such as 5MM, 10MM, so as to disassemble the lamp string into finished products with various lengths, such as 0.5 meters, 1 meter, 1.5 meters, 2 meters; moreover, the application of the utility model is extensive and can be applied to various processing equipment in the lamp string industry, such as the full-automatic copper wire lamp string shearing machine, the full-automatic shearing and winding machine and the full-automatic copper wire lamp string battery box soldering machine.

Specific implementation manners

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the core concept of the present utility model and the following embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Embodiment 1, a synchronous clamping, cutting and wire removing structure, as shown in Figure 1 , Figure 2 , Figure 5 and Figure 9 , includes a clamping assembly 4 for clamping the lamp string 1 on the rotatable mold bar 2. A cutter assembly 3 for cutting the lamp string 1 is further provided between the mold bar 2 and the clamping assembly 4. The clamping assembly 4 stretches the lamp string 1 through a moving mechanism 6.

[0037] Specifically, after the LED copper wire lamp string or alloy wire lamp string is positioned with the help of the mold bar 2 to complete the finished product, taking advantage of the fact that the positions of the lamp strings 1 on the mold bar 2 are the same, through synchronous clamping by the clamping assembly 4. After the clamping assembly 4 clamps at a specific position of the lamp string 1, the cutter assembly 3 is then used to synchronously cut the corresponding position of the lamp string 1, and then the moving mechanism 6 is used to pull the lamp string 1 to disassemble it from the mold bar 2. Finally, the automatic multi-segment one-time disassembly of the lamp string 1 on the mold bar 2 is realized, saving manpower and improving the demolding efficiency, thus solving the problem of low overall production efficiency caused by the retention of the mold bar 2. Compared with the existing method, the production efficiency is increased by at least 30%.

[0038] Furthermore, the lamp string 1 can be an LED copper wire lamp string or an alloy wire lamp string. The mold strip 2 is made of aluminum alloy. The clamping position of the clamping component 4 is determined according to the length of the lamp string to be produced. The clamping component 4 is connected to the moving mechanism 6 through the connecting plate 5. The moving mechanism 6 can be a cylinder or a hydraulic rod connected to the clamping component 4, as long as it can pull the clamping component 4 to perform a linear reciprocating motion. When the clamping component 4 approaches the mold strip 2, it clamps the lamp string 1 on the mold strip 2. When the clamping component 4 moves away from the mold strip 2, it pulls the sheared lamp string 1 off the mold strip 2 to complete the blanking.

[0039] Example 2. On the basis of Example 1, a synchronous clamping, cutting, and wire-disconnecting structure, as Figure 6 shown, the clamping component 4 includes several pairs of matching fixed clamping jaws 401 and movable clamping jaws 402, and the gap between each pair of movable clamping jaws 402 and the fixed clamping jaws 401 is adjustable. The number of pairs of movable clamping jaws 402 and fixed clamping jaws 401 depends on the finished length of the required lamp string 1, which is convenient for realizing the cutting of lamp strings 1 with multiple lamp distances and for making lamp strings 1 with multiple required finished lengths. The gap between each pair of movable clamping jaws 402 and the fixed clamping jaws 401 is adjustable, which is convenient for clamping lamp strings of various specifications and sizes. Further, the clamping component 4 clamps the wire head position of the lamp string 1, and each pair of movable clamping jaws 402 and fixed clamping jaws 401 are evenly spaced.

[0040] Example 3. On the basis of Example 2, a synchronous clamping, cutting, and wire-disconnecting structure, as Figure 7 shown, the fixed clamping jaw 401 is connected to the jaw fixing part 403, and the movable clamping jaw 402 is connected to the cross pull rod 406. The cross pull rod 406 is slidably connected to the jaw fixing part 403. When the cross pull rod 406 slides, it drives the movable clamping jaw 402 to slide relative to the fixed clamping jaw 401, thereby realizing the gap adjustment between the movable clamping jaw 402 and the fixed clamping jaw 401.

[0041] Furthermore, the jaw fixing part 403 is connected with a mounting plate 407. The bottom of the mounting plate 407 is connected with an opening and closing cylinder 405. The piston of the opening and closing cylinder 405 is connected to the cross pull rod 406 through an L-shaped plate. By the movement of the piston of the opening and closing cylinder 405, the cross pull rod 406 is driven to slide, and then the movable clamping jaw 402 is driven to slide relative to the fixed clamping jaw 401 on the jaw fixing part 403. Moreover, evenly spaced mounting holes are provided on the bottom surfaces of the jaw fixing part 403 and the cross pull rod 406. The fixed clamping jaw 401 and the movable clamping jaw 402 are both detachably connected to the mounting holes by bolts, and the mounting positions of the fixed clamping jaw 401 and the movable clamping jaw 402 can be adjusted in time according to production needs.

[0042] Example 4. On the basis of Example 3, a synchronous clamping, cutting, and wire-disconnecting structure, as Figure 7As shown, a limiting block 404 for blocking the sliding of the stop cross tie rod 406 is further provided on the jaw fixing member 403. The limiting block 404 is used to limit the maximum gap between the movable jaw 402 and the fixed jaw 401. Further, the limiting block 404 is connected to the jaw fixing member 403. When the piston of the opening and closing cylinder 405 slides to a certain extent, the limiting block 404 blocks the L-shaped plate, and the maximum sliding distance of the piston is the maximum gap between the movable jaw 402 and the fixed jaw 401. The maximum gap between the movable jaw 402 and the fixed jaw 401 is the maximum specification of the lamp string that can be clamped.

[0043] Embodiment 5, based on any one of Embodiments 1-4, a synchronous clamping, cutting, and wire removing structure, as Figure 1 、 Figure 8 shown, the cutter assembly 3 includes a plurality of cutters 302 connected to the substrate 301, and the cutters 302 correspond to the fixed jaws 401 one by one. Facilitate synchronous shearing of the lamp string 1 by each cutter 302 after clamping the lamp string 1. Further, the cutter assembly 3 shears the wire tails of the lamp string 1, and the positions of the cutters 302 are lower than those of the clamping assembly 4.

[0044] Embodiment 6, based on Embodiment 5, a synchronous clamping, cutting, and wire removing structure, a cutter seat 303 is provided on one side of the substrate 301 close to the die bar 2, and a plurality of uniformly spaced mounting grooves are provided on the cutter seat 303. The cutters 302 are detachably connected to the cutter seat 303 through the mounting grooves. Ensure that the number of cutters 302 is adjustable, the positions of the cutters 302 on the cutter seat 303 are adjustable, and thus the distance between two adjacent cutters 302 is adjustable. Further, the cutters 302 and the mounting grooves are detachably connected by bolts, and the number of cutters 302 and the distance between two adjacent cutters 302 are determined according to production needs.

[0045] Embodiment 7, based on Embodiment 6, a synchronous clamping, cutting, and wire removing structure, as Figure 4 shown, a liftable wire guiding plate 304 is connected between the cutter 302 and the die bar 2, and the wire guiding plate 304 is higher than the cutter 302 when lifted. When pulling the lamp string 1, the wire guiding plate 304 is lifted to prevent the lamp string 1 from being damaged by hitting the cutter 302 due to elastic shaking. Further, the wire guiding plate 304 is rotatably connected to the substrate 301, and the rotating structure can be a cylinder hinged to the wire guiding plate 304. A support spring is provided on the cylinder. When the cutter shears, the wire guiding plate 304 is pressed down, and when the cutter returns to its position, the support spring lifts the wire guiding plate 304 under the action of elastic force.

[0046] Embodiment 8, based on Embodiment 7, a synchronous clamping, cutting, and wire removing structure, as Figure 3As shown in the figure, on the side of the substrate 301 facing away from the cutting knife 302, there are a number of wire columns 308 evenly spaced apart, and the wire columns 308 correspond one-to-one with the cutting knife 302. The wire columns 308 are used to guide the lamp string 1 when pulling the lamp string 1. The wire columns 308 are connected to the substrate 301 through a limiting plate 307. The limiting plate 307 is located on the side of the substrate 301 facing away from the cutting knife 302 and is used to limit the return displacement of the cutting knife 302.

[0047] Embodiment 9. On the basis of Embodiment 8, a synchronous clamping, cutting, and wire-disconnecting structure, as Figure 8 shown, on the substrate 301, there is a double-rod cylinder 305 for adjusting the distance between the cutting knife 302 and the die bar 2. On the substrate 301, there is also a slide rail 306 arranged in parallel and at intervals with the double-rod cylinder 305. The double-rod cylinder 305 can drive the cutting knife 302 to slide closer to and away from the die bar 2 to achieve synchronous shearing of the lamp string 1 and the return of the cutting knife 302. The slide rail 306 is used to reduce friction. Further, both the double-rod cylinder 305 and the slide rail 306 can improve the stability of the cutting knife 302 during movement. The slide rail 306 can be a chute arranged on the substrate 301, a slider connected to the cutting knife seat 303, or a ball guide rail arranged on the substrate 301 and a slide bar connected to the cutting knife seat 303.

[0048] Embodiment 10. On the basis of Embodiment 9, a synchronous clamping, cutting, and wire-disconnecting structure, as shown in Figure 10, the die bar 2 is rotatably connected to a rotating frame, and the rotating frame is arranged on the die bar conveying mechanism 7. The rotating frame can make the die bar 2 rotate when pulling the lamp string 1. The die bar conveying mechanism 7 is used to realize continuous conveying of the die bar 2 wound with the lamp string 1 and achieve continuous disassembly of the finished lamp string 1. Through the combination of clamping, shearing, and disassembly with automatic feeding and discharging steps, a stable and efficient automated production process is achieved.

[0049] Further, the die bar 2 is driven by a servo motor to rotate at a high speed to ensure that the appropriate tension of the lamp string 1 during disassembly is controlled by the motor torque, and to ensure the accurate consistency of the disassembly length of the finished lamp string 1. And unified motion control is performed on the synchronous clamping, synchronous shearing, and synchronous disassembly after the lamp string 1 is wound around the die bar 2, realizing high-efficiency full automation during the disassembly process of the die bar 2.

[0050] As Figure 11 shown, using the synchronous clamping, cutting, and wire-disconnecting structure of the present invention for die bar disassembly, the main steps are as follows:

[0051] The first step: Feed the die bar 2 wound with the whole lamp string 1 through the die bar conveying mechanism 7, and automatically position it so that the side where the lamp is located rotates to be close to the clamping assembly 4;

[0052] The second step: Control the clamping assembly 4 to approach the die bar 2 and synchronously clamp the wire head position of the lamp string 1 to complete the clamping of the lamp string 1;

[0053] Step 3: Control the cutting tool assembly 3 to approach the mold bar 2, and synchronously cut the tail position of the wire of the lamp string 1. After the cutting is completed, control the cutting tool assembly 3 to return to a position away from the mold bar 2, and the wire guide plate 304 rises to complete the cutting of the lamp string 1;

[0054] Step 4: Control the clamping assembly 4 to move away from the mold bar 2 to pull the head of the lamp string, thereby driving the mold bar 2 to rotate and completing the disassembly of the mold bar 2;

[0055] Step 5: Control the movable jaw 402 of the clamping assembly 4 to slide to release the head of the lamp string, and complete the blanking of the finished product of the lamp string 1.
