Description

Technical Field

[0001] The present invention relates to the technical field of clamps, in particular to a double-row cable core wire installation clamp. Background Art

[0002] Cables are commonly used interconnecting components for electronic products. They are generally made of cable signal core wires and connectors welded together. The current fixtures used to clamp the core wires and connectors are generally simple in structure and cannot handle the processing of double-row multi-core wires of connectors with four rows of welding positions. Multiple cable clamping is required during processing. The core wire to be welded needs to be mounted in a wire clamp for core wire cutting, stripping, tinning and other processes. Then the core wire to be welded is removed and placed together with the connector into another fixture for pre-alignment and welding. That is, the core wire pretreatment and core wire welding are clamped by different fixtures, which results in a long time consumption and low processing efficiency.

[0003] To effectively address the need for multiple wire clamping during processing, the applicant sought to design a fixture that could perform a single clamping operation from wire processing to welding completion. However, due to the narrow space between the four rows of connectors with soldering positions, simply combining the existing wire clamp with the connector clamp was unable to simultaneously complete the stripping, tinning, upper and lower row pre-alignment processing of a large number of wires within the narrow space, as well as the auxiliary loading fixture removal after welding. Summary of the Invention

[0004] To address these issues, the present invention provides a novel, time-saving, and highly efficient double-row cable core wire installation fixture. This fixture allows for single-step clamping, from core wire processing to welding completion. For multi-row connection welding, this double-row cable core wire installation fixture represents an innovative breakthrough in cable processing and clamping for the automation industry.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a new double-row cable core wire installation fixture, including a positioning plate, a core wire clamping assembly and a connector fixing frame, the positioning plate is provided with a positioning seat, the positioning seat is movably connected to the core wire clamping assembly, the positioning plate is also connected to a fixing plate, and the connector fixing frame is movably connected to the fixing plate.

[0006] Preferably, the core wire clamping assembly includes a splint, a pressure plate, a core wire spring clamp and a rolling bearing. The two splints rotate on the positioning seat through a pin shaft respectively. The pressure plate is rotatably connected to the splint. The two splints are respectively provided with core wire spring clamps. Several core wire clamping grooves are distributed on the core wire spring clamps. Two rolling bearings are respectively provided on the same side of the two splints.

[0007] Preferably, the connector fixing frame includes a swing arm and a fixed block, one end of the swing arm is rotatably connected to the fixed plate through a pin, and the fixed block is connected to the other end of the swing arm. A slot is provided on the fixed block, and a first limit block and a second limit block are provided above the slot.

[0008] Preferably, a first positioning block and a second positioning block are provided on the fixing plate, the first positioning block is fixed on the fixing plate, the second positioning block is rotatably provided on the second fixing plate through a pin shaft, an open positioning groove is formed between the first positioning block and the second positioning block, and the positioning groove is used to fix the cable assembly, and a third positioning block is also provided on the fixing plate, the third positioning block is provided in front of the first positioning block and the second positioning block, and the third positioning block is provided with an open positioning hole, which is used to constrain the core wire.

[0009] Preferably, the two clamping plates are respectively provided with rotatable clamping plate locks, and after the core wire is welded to the connector, the clamping plate locks are opened by the cooperation of automated equipment.

[0010] Preferably, a rotatable clamp total lock is provided on one of the clamps, and the clamp total lock is elastically connected to one of the clamps through an elastic member, and a card slot corresponding to the clamp total lock is provided on the other clamp. Before the connector fixing frame is screwed into the core wire clamping assembly, the clamp total lock is opened by the cooperation of automated equipment, and the core wire clamping assembly is screwed in half open, and the connector fixing frame is screwed into the core wire clamping assembly.

[0011] The beneficial effects of the present invention are: the structural design of the present invention is novel, the core wire and the connector are clamped at one time, and the splint lock provided on the core wire clamping assembly is interlocked with the clamp total lock, and must be opened in accordance with the processing sequence, that is, after the clamp total lock locks the two core wire clamping assemblies, the splint lock cannot be opened, which can prevent the core wire pressing splint from loosening and improve reliability. Only when the clamp total lock is opened, and the clamp total lock is opened by the cooperation of automated equipment before the welding process, can the splint lock be opened and the clamping plate be loosened after the two core wire clamping assemblies are separated.

[0012] In a narrow space, a large number of core wires can be stripped and tinned at the same time. The upper and lower rows are pre-aligned before welding. That is, the two end faces of the connector are aligned with the core wires to be welded to the two end faces of the connector. The fixture is opened or closed online through automated equipment. Online means that the production process does not stop. During the continuous production process, the core wire and the connector welding position are aligned by the fixture, and the welding operation is completed, achieving high precision and high consistency. There is no need for multiple cable arrangement and clamping. All wire processing and welding operations are completed at one time, shortening working hours and improving processing efficiency.

[0013] The clamp can complete the entire processing by clamping the workpiece to be processed at one time, divide the core wires of the cable into two rows and insert them into the two core wire clamping assemblies respectively, and install the connector on the connector fixing frame. When the clamped core wires are cut, stripped and tinned in conjunction with the automated equipment, there will be no interference with the two rows of core wires that have been welded in the middle of the connector on the connector fixing frame. After the core wires to be welded have been cut, stripped and tinned, the two core wire clamping assemblies are opened by the automated equipment and the connector fixing frame is driven to rotate and screw into the clamp, so that the connector is positioned between the two rows of core wires to be welded, and then the two core wire clamping assemblies are closed, so that the two rows of core wires are respectively welded to the two end surfaces of the connector, which is quick and convenient. Moreover, since the cable and the connector are both clamped in the clamp, the core wires of the two core wire clamping assemblies are welded to the outer end surface of the connector through the automated equipment. After the assembly and welding are completed, as soon as the two side plates on the clamp are opened, the core wire is detached from the core wire spring clamp, and the finished product can be quickly unloaded from the clamp. The existing fixture structure cannot cooperate with automated equipment to perform continuous processing without stopping the line. The present invention does not require disassembly of the fixture to re-arrange the wire position during the entire processing period, and the core wire processing and welding are completed online.

[0031] See also Figure 1-16 As shown, the present invention relates to a new type of double-row cable core wire installation fixture, including a positioning plate 1, a core wire clamping assembly 2 and a connector fixing frame 3. The positioning plate 1 is provided with a positioning seat 4, and the positioning seat 4 is movably connected to the core wire clamping assembly 2, and the core wire clamping assembly 2 is used to clamp the core wire to be processed. The positioning plate 1 is also vertically connected to a fixing plate 5, and the connector fixing frame 3 is movably connected to the fixing plate 5 and can be rotated 90 degrees around the fixing plate 5. The connector is installed on the connector fixing frame 3, the cable assembly is installed on the fixing plate 5, and the core wire of the cable assembly is passed through the core wire clamping assembly 2.

[0032] The present invention uses the following process:

[0033] First, clamp the core wire to be processed into the core wire clamping assembly 2, and clamp the connector into the connector fixing frame 3, as shown in the figure. Figure 2 State, and then the core wire clamped into the core wire clamping assembly 2 is subjected to a series of processing such as cutting, stripping and varnishing by the automated equipment. At this time, the core wire clamping assembly 2 is half opened by the automated equipment, and the connector fixing frame 3 is screwed into the core wire clamping assembly 2, as shown in FIG. Figure 1 State, after the connector fixing frame 3 is clamped on the core wire clamping assembly 2, the conductor of the processed core wire is automatically aligned with the two rows of pre-welding positions outside the connector, such as Figure 3-4 , there is no need to manually align the core wires with the connector, simplifying the traditional multiple clamping and alignment actions. The aligned double-row core wires are welded to the outer sides of the connector through automated equipment to obtain the finished product, such as Figure 16 Although the overall structure is simple, the overall design is very clever. How to achieve the online (without stopping the production line) to achieve the clamping of the workpiece to be processed and complete the entire processing process at one time? The existing fixtures cannot achieve this. They all use multiple fixtures to complete the core wire processing first, and then clamp and weld the core wire and the connector. The present invention uses a simple structure to achieve that after the core wire is clamped and a series of processes such as wire cutting, stripping, and paint dipping are completed, the fixture is opened online to complete the connector clamping and alignment with the core wire.

[0034] Preferably, the core wire clamping assembly 2 includes a splint 21, a pressure plate 22, a core wire spring clamp 23 and a rolling bearing 24. The two splints 21 are respectively rotated on the positioning seat 4 through a pin shaft. The pressure plate 22 is rotatably connected to the splint 21. The two splints 21 are respectively provided with core wire spring clamps 23. Several core wire clamping grooves are distributed on the core wire spring clamps 23. Two rows of core wires are respectively passed through the core wire clamping grooves of the two core wire spring clamps 23. The pressure plate 22 is attached to the splint 21 to prevent the core wire from detaching. Two rolling bearings 24 are respectively provided on the same side of the two splints 21.

[0035] Preferably, the connector fixing frame 3 includes a swing arm 31 and a fixed block 32. One end of the swing arm 31 is rotatably connected to the fixed plate 5 through a pin, and the fixed block 32 is connected to the other end of the swing arm 31. A slot 321 is provided on the fixed block 32, and a first limit block 33 and a second limit block 34 are provided above the slot 321. When the connector is inserted into the slot 321, the first limit block 33 and the second limit block can limit the movement of the connector, thereby fixing the position of the connector.

[0036] Preferably, the fixing plate 5 is provided with a first positioning block 51 and a second positioning block 52. The first positioning block 51 is fixedly provided on the fixing plate 5, and the second positioning block 52 is rotatably provided on the second fixing plate 5 via a pin. An open positioning groove is formed between the first positioning block 51 and the second positioning block 52. The positioning groove 54 is used to fix the cable body of the cable assembly. The fixing plate 5 is also provided with a third positioning block 53. The third positioning block 53 is provided in front of the first positioning block 51 and the second positioning block 52. The third positioning block 53 is provided with an open positioning hole. The positioning hole is used to constrain the core wire to prevent the core wire from spreading. The fixing plate 5 is fixed and the connector fixing frame 3 is rotated into the core wire clamping assembly 2 with the cooperation of the automation equipment.

[0037] Preferably, a rotatable clamp lock 25 is provided on each of the two clamps 21. When the clamping plate 22 is pressed against the surface of the clamp 21, the first bayonet can clamp the clamping plate 22 to fix its position. The clamping plate 22 can be separated by opening the clamp lock 25.

[0038] Preferably, a rotatable clamp total lock 26 is provided on one of the splints 21, and the clamp total lock 26 is elastically connected to the splint through an elastic member, and a card slot corresponding to the clamp total lock 26 is provided on the other splint 21. When the two splints 21 rotate inward relative to each other, the clamp total lock 26 passes through the card slot and clamps the surface of the other splint 21. The elastic force of the elastic member fixes the clamp total lock 26, thereby locking the position of the two core wire clamping assemblies 2.

[0039] When the two core wire clamping assemblies 2 are fixed by the clamp total lock 26, the splint lock 25 cannot be opened directly. This can prevent the splint lock 25 from being accidentally touched, which may cause the clamping plate 22 to loosen and the core wire to loosen. Only by opening the clamp total lock 26 first to separate the two core wire clamping assemblies 2 can the splint lock 25 be opened.

[0040] A multi-core wire double-row automatic welding machine using the above-mentioned clamp includes a machine table 6, on which a clamp transfer mechanism 7, a tinning mechanism 8, a conveying circulation mechanism 9 and a blanking mechanism 10 are arranged from left to right. A cutting and peeling mechanism 20 is provided next to the clamp transfer mechanism 7, and a clamp transfer mechanism 30 is provided between the clamp transfer mechanism 7 and the conveying circulation mechanism 9. A rotation alignment mechanism 40 and a clamp flipping mechanism 50 are provided on one side of the conveying circulation mechanism 9, and a double-head welding mechanism 60 is provided on the other side. The rotation alignment mechanism 40 is provided on the left side of the double-head welding mechanism 60, and the clamp flipping mechanism 50 is correspondingly provided at the center line of the double-head welding mechanism 60. The clamp is clamped on the clamp transfer mechanism 7, and the clamp transfer mechanism 7 drives the clamp to move to the cutting and peeling mechanism 20 to process the core wire, and then drives the clamp to move to the tinning mechanism 8 pairs of core wires are tinned and then transferred to the fixture transfer mechanism 30. The fixture transfer mechanism 30 then transfers the fixture to the conveying circulation mechanism 9. The conveying circulation mechanism 9 drives the fixture to move to the rotating alignment mechanism 40, aligns the core wire with the connector, and moves to the double-head welding mechanism 60 and the fixture flipping mechanism 50. The double-head welding mechanism 60 first welds the front of the product, that is, welds a row of core wires distributed on the same side of the fixture with the connector, and then flips the fixture through the fixture flipping mechanism 50, and then the double-head welding mechanism 60 welds the back of the product, that is, welds a row of core wires distributed on the other side of the fixture with the connector. After completing the welding process, the conveying circulation mechanism 9 drives the fixture to move to the unloading mechanism 10, and the unloading mechanism 10 clamps the fixture and transfers it to the collection station. Finally, the staff takes the finished product out of the fixture.

[0041] Preferably, if Figure 13-15As shown, the rotation alignment mechanism 40 includes a third bracket 41, a push-pull mechanism 42 and a separation mechanism 43. The third bracket 41 is arranged on the machine table 6. The push-pull mechanism 42 includes a push-pull cylinder 421, a push-pull plate 422 and a slide rail 423. The push-pull cylinder 421 is arranged on the third bracket 41. The push-pull plate 422 is connected to the push-pull cylinder 421. The slide rail 423 is slidably arranged on the third bracket 41 and connected to the push-pull plate 422. The rear end of the slide rail 423 is vertically connected to a block, which is arranged behind the connector fixing frame 3 of the fixture. The separating mechanism 43 includes a movable cylinder 431 and a cam plate 432. The movable cylinder 431 is fixed on the third bracket 41. The cam plate 432 is transmission-connected to the movable cylinder 431. The cam plate 432 is provided with an arrow-shaped block 4321 and a Y-shaped guide groove. When the conveying circulation mechanism 9 drives the clamp to move to the rotary alignment mechanism 40, the movable cylinder 431 drives the cam plate 432 to move. The arrow-shaped block 4321 of the cam plate 432 is passed between the rolling bearings 24 of the two core wire clamping assemblies 2. The two rolling bearings 24 are arranged along the Y-shaped guide groove. The guide groove 4322 slides, and the clamp total lock buckle 26 vibrates after colliding with the rotary alignment mechanism 40, disengaging from the card slot and rotating outward, loosening the two core wire clamping assemblies 2. As a result, the two rolling bearings 24 slide relative to the deep end of the Y-shaped guide groove 4322 during the process of the rotary alignment mechanism 6 driving the cam plate 432 to approach the clamp. The distance between the two rolling bearings 24 increases, causing the two core wire clamping assemblies 2 to open and separate. At this time, the push-pull cylinder 421 drives the slide rail 423 to move through the push-pull plate 422, and the block on the slide rail 423 abuts against the connector fixed The surface of the fixed frame 3 is rotated, driving the connector fixing frame 3 to rotate, causing the connector mounted on the connector fixing frame 3 to rotate and enter between the two core wire clamping assemblies 2. Then, the movable cylinder 431 drives the cam plate 432 to move back, and the rolling bearing 24 slides outward along the trajectory of the Y-shaped guide groove 4322, bringing the two core wire clamping assemblies 2 together. As a result, the two rows of core wires threaded through the two core wire clamping assemblies 2 are pressed against the upper and lower surfaces of the connector respectively. The clamp main lock 26 is reset under the elastic force of the elastic member, relocking the two core wire clamping assemblies 2. The rotary alignment mechanism 40 cooperates with the clamp to enable the clamp to be opened online, realizing multi-process operation.

[0042] The invention has a novel structure design. By clamping the cable core wires and connectors at one time, a large number of core wires can be stripped, tinned and other processes can be completed at one time in a narrow space. The upper and lower rows can be pre-aligned before welding. During the operation, the clamp can be opened online by docking with the equipment (the production line can be continuously produced without stopping the line). Figure 2The connector with two rows of wires already welded is fixed on the connector fixing frame 3. Multiple core wires are manually clamped in the core wire spring clamp. The core wires clamped in the clamp are processed by automated equipment such as core wire cutting, stripping, and tinning. Then, the core wire clamping assembly is half-opened by the rotation alignment mechanism 40 and the connector fixing frame 3 is rotated into the core wire clamping assembly. Figure 14-15 After the clamp is closed, the upper and lower core wires (core wires on both sides of the outside) are aligned with the connector welding positions to complete the welding operation with high precision and high consistency. This solves the traditional problem of needing to arrange the wires and clamp them again in each process. The present invention does not require multiple arrangement and clamping of the wires, which shortens the working hours and improves the processing efficiency.

[0043] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
