Description

Technical Field

[0001] The present invention relates to the technical field of electronic connector welding, and in particular to a special welding device for electronic connectors based on a flattening structure. Background Art

[0002] As an indispensable component of electronic equipment, electronic connectors play a key role in connecting electronic components and transmitting current or signals. There are many types of electronic connectors, which can be divided into ring connectors, rectangular connectors, etc. according to their appearance. Taking ring connectors as an example, their welding work usually adopts a unified wire stripping method in the existing technology, that is, the insulation layer of all the ends of the conductive wires to be connected is stripped off at one time, and then the welding terminals of the ring connector are press-welded to the conductive wires of the wiring harness. However, this seemingly convenient method has obvious disadvantages.

[0003] Since all ends of the conductive wires are exposed, during the welding process, especially when the operating space is limited or the wire harness is long, they are easily affected by external forces, such as the operator's touch or the weight of the wire harness, causing the conductive wires to fold, tangle or even knot. This not only greatly increases the difficulty of the welding operation and reduces work efficiency, but also directly affects the welding quality, causing problems such as cold solder joints and short circuits. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a special welding equipment for electronic connectors based on a flattened structure, which can effectively solve the problem in the prior art that the ends of the conductive wires are exposed. During the welding process, especially when the operating space is limited or the wire harness is long, it is extremely susceptible to external forces, such as the operator's touch or the weight of the wire harness, which causes the conductive wires to fold, tangle or even knot. This not only greatly increases the difficulty of the welding operation and reduces work efficiency, but also directly affects the welding quality and causes problems such as cold soldering and short circuits.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a special welding device for electronic connectors based on a flattened structure, comprising:

The wire stripping group also includes a three-finger clamp set on the mounting disk and a wire cutting piece installed at the three clamping ends of the three-finger clamp. One end of the three-finger clamp passes through the mounting disk and is connected to the circular plate.

[0014] Furthermore, the tangent piece includes an arc-shaped supporting plate fixedly arranged at the clamping end of the three-finger clamp, and an annular plate that slides along the front-back direction and has two semicircular cutters on the arc-shaped inner wall is installed on the side of the arc-shaped supporting plate away from the clamping end of the three-finger clamp. One end of the semicircular cutter is fixedly connected to a magnetic boss, and a U-shaped matching groove is provided at the other end of the semicircular cutter. The annular plate on the side away from the center of the annular tube is fixedly connected to the arc-shaped slider through a telescopic plate.

[0015] Furthermore, the clamping group includes a connecting plate in a cross shape and fixedly connected to the four circular plates respectively. A conical rod is fixedly connected to the center position of the connecting plate. The front end of the conical rod is fixedly connected to a clamping plate that is slidably arranged inside four rectangular slides and is in an X shape. The clamping plate is fixedly connected to the position of the clamping groove in the rectangular slide corresponding to the clamping groove. An actuator that can be used to clamp the front end of the wiring harness is provided between the clamping plate and the connecting plate.

The arc-shaped mounting plate 2 is fixedly connected to the inner wall of the first annular pipe through two strip-shaped telescopic plates. At one end of the arc-shaped mounting plate 2 away from the arc-shaped mounting plate 1, there is also fixedly connected a rectangular mating plate that always fits against the outer wall of the tapered rod. On the side where the arc-shaped mounting plate 1 and the arc-shaped mounting plate 2 are close to each other, there are mating clamping plates that limit and clamp the outer wall of the wire harness and are slidably mounted through springs.

[0017] Further, four groups of annular ring groups are slidably mounted inside the second annular pipe along the circumferential direction.

In order to enhance the overall strength and hardness during the wire harness installation process, there is no need to perform a wire stripping operation on the wire harness before inserting and installing it into the first annular pipe, reducing the risk of wire harness bending caused by gravity or contact with the inner wall of the first annular pipe. After the four wire harnesses complete the limiting work, through the reciprocating movement of the upper rack gear, synchronous stripping of the insulating layers of the four wire harnesses and the material discharging operation are achieved. Through this design of realizing multiple functions with a single action, not only significantly improves the working efficiency of wire harness insulating skin stripping, simplifies the operation process, but also enhances the coherence and fluency of the welding work. Without frequent switching or adjustment, multiple wire harnesses can be continuously stripped of their insulating skins and the material can be discharged, thus shortening the welding preparation time and improving the overall production efficiency.

The wire stripping group 232 also includes a three-finger clamp 2323 arranged on the mounting disk 1 231 and a wire cutting piece 2324 installed at the three clamping ends of the three-finger clamp 2323. One end of the three-finger clamp 2323 penetrates the mounting disk 1 231 and is connected to a circular plate.

[0047] The tangent piece 2324 includes an arc-shaped supporting plate 23241 fixedly arranged at the clamping end of the three-finger clamp 2323, and an annular plate 23242 that slides along the front-back direction and has two semicircular cutters 23243 on the arc-shaped inner wall is installed on the side of the arc-shaped supporting plate 23241 away from the clamping end of the three-finger clamp 2323. One end of the semicircular cutter 23243 is fixedly connected to a magnetic boss 23244, and a U-shaped matching groove is provided at the other end of the semicircular cutter 23243. The annular plate 23242 on the side away from the center of the annular tube 21 is fixedly connected to the arc-shaped slider 2321 through a telescopic plate.

[0048] The clamping group 233 includes a connecting plate 2331 in a cross shape and fixedly connected to four circular plates respectively. At the central position of the connecting plate 2331, a tapered rod 2332 is fixedly connected. At the front end of the tapered rod 2332, a clamping plate 2333 in an X shape and slidably arranged inside four rectangular chutes 211 is fixedly connected. Elastic clamping blocks are fixedly connected to the clamping plate 2333 corresponding to the positions of the clamping grooves in the rectangular chutes 211. An actuator 2334 for clamping the front end of the wire harness is arranged between the clamping plate 2333 and the connecting plate 2331.

[0049] The actuator 2334 includes two arc-shaped mounting plates 23341 and 23342 which are opposite in position and suspended inside the first annular tube 21. The arc-shaped mounting plate 23341 is fixedly connected to the inner wall of the first annular tube 21 through a rectangular block. The arc-shaped mounting plate 23342 is fixedly connected to the inner wall of the first annular tube 21 through two strip-shaped telescopic plates 23343 and is located at one end of the arc-shaped mounting plate 23342 far from the arc-shaped mounting plate 23341. A rectangular mating plate 23344 that always fits against the outer wall of the tapered rod 2332 is also fixedly connected. On the side where the arc-shaped mounting plate 23341 and the arc-shaped mounting plate 23342 are close to each other, mating clamping plates 23345 for limiting and clamping the outer wall of the wire harness are slidably installed through springs.

[0050] Four groups of annular ring groups are slidably installed inside the second annular tube 22 along the circumferential direction. Each group of annular ring groups includes two annular rings 221 connected by sliding blocks. The front end of the sliding block is in contact with the outer wall of the arc-shaped block through a pushing plate. At the rear end of the annular ring 221, a second mounting plate 222 for placing an annular connector and having four semi-circular tubes installed on its end face along the circumferential direction is fixedly connected. Arc-shaped grooves 223 are provided at the positions corresponding to the four semi-circular tubes on the second annular tube 22.

[0051] The adjusting member 24 includes four round-headed rods 241 arranged along the circumferential direction and always slidably arranged inside the arc-shaped grooves 223 and located between the two annular rings 221. The other end of the round-headed rod 241 is fixedly connected with a U-shaped pushing plate 242 with an opening facing forward and slidably arranged on the end face of the semi-circular tube.

[0052] The driving member 11 includes a gear shaft 111 fixedly connected to the output shaft of an external motor and rotatably installed in the welding table body 1. Rack bars 112 are respectively engaged with the upper and lower ends of the gear shaft 111. Among them, the lower rack bar 112 is magnetically connected to the tapered rod 2332 through a magnetic rod 113, and a magnetic pushing block 114 is fixedly connected to the upper rack bar 112 corresponding to the position of the magnetic block.

[0053] During specific operation, the installation and limiting work of the annular connector and the wire harness:

[0054] For the small-batch welding of the annular connector and the wiring harness, first, the annular connector is inserted into the interior of the annular tube 22, and the four welding terminals of the annular connector are respectively inserted into the corresponding semicircular tubes, and the annular connector and the mounting plate 222 are fixed and connected into a whole by an external limiting mechanism, and then the four separate wiring harnesses are inserted along the annular tube 1 21 so that the ends of the wiring harnesses enter the interior of the annular tube 22 and are tightly attached to the welding terminals of the annular connector (a step-by-step welding method is adopted, that is, a single wiring harness is first welded independently, and then the final assembly is carried out after the welding work of each wiring harness is completed. The advantage of this welding method is that it ensures the accessibility and detectability of each welding point, thereby avoiding the difficulty in locating and troubleshooting the problem of cold welding caused by the large number of wiring harnesses and the complex layout after all wiring harnesses are integrated. In the welding process of a single wiring harness, due to the wiring harness being in a In an independent state, it is beneficial to adjust the welding angle and welding point position to adapt to different welding process requirements and design specifications. In addition, in order to enhance the overall strength and hardness of the wiring harness during installation, there is no need to strip the wiring harness before inserting it into the annular tube 21. Retaining the insulation can not only avoid the conductive wire from becoming messy and entangled due to external force after stripping, but also the hardness of the insulation itself helps to reduce the risk of wiring harness bending caused by gravity or contact with the inner wall of the annular tube 21 during insertion into the annular tube 21. Therefore, step-by-step welding, independent adjustment, and insulation protection are adopted. Design measures effectively improve the quality and reliability of wiring harness welding, reduce the risk of welding defects, and enhance the anti-interference ability of the wiring harness during installation). After completing the installation limit of the annular connector and the initial placement of the wiring harness, the external motor is controlled to drive the gear shaft 111 to rotate.

[0055] During the rotation of the gear shaft 111, the upper and lower racks 112 are driven away from each other, and the rack 112 at the bottom is pulled by the magnetic rod 113 to move along the annular tube 1 21. During the movement of the tapered rod 2332, its front end will synchronously drive the clamping plate 2333 to slide along the rectangular slide 211. As the tapered rod 2332 moves, the tapered outer wall of the tapered rod 2332 pushes the four rectangular matching plates 23344 in the circumferential direction to move. When the four rectangular matching plates 23344 move, they push the corresponding arc-shaped mounting plates 2 2 3342 moves (since the upper end of the arc-shaped mounting plate 23342 is fixedly connected to the inner wall of the annular tube 1 21 through two strip-shaped telescopic plates 23343, there will be no obstruction when the arc-shaped mounting plate 23342 is subjected to a pushing force), and as the outer wall of the tapered rod 2332 continues to push the rectangular matching plate 23344, the distance between the arc-shaped mounting plate 23342 and the arc-shaped mounting plate 1 23341 gradually decreases, and finally the clamping and limiting work of the outer wall of the wiring harness is completed by the matching clamping plate 23345 set on the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342.

[0056] When the arc-shaped mounting plate 23341 and the arc-shaped mounting plate 23342 are close to each other and work together to achieve the limited clamping of the wiring harness, the spring sliding mechanism can effectively buffer and absorb the force, thereby avoiding the rigid force from directly acting on the outer wall of the wiring harness, greatly reducing the risk of damage to the outer wall of the wiring harness. At the same time, U-shaped grooves are provided at both ends of the arc-shaped mounting plate 1 23341, and correspondingly, matching blocks are fixedly connected at both ends of the arc-shaped mounting plate 23342 at the corresponding positions of the U-shaped grooves. Therefore, when the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342 are close to each other, the U-shaped groove and the matching block are precisely matched, guiding the distance between the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342 to be further reduced, thereby significantly improving the clamping force of the wiring harness.

[0057] By applying appropriate pressure to the wire harness, it not only protects the wire harness from mechanical damage, but also ensures the stability and reliability of the wire harness during the welding process, effectively preventing the problem of welding quality degradation or even welding failure caused by the wire harness moving or shaking during the welding process.

[0058] Taking any wire cutting piece 2324 as an example, when the conical rod 2332 is pulled by the magnetic rod 113, the connecting plate 2331 also moves synchronously under the drive of the conical rod 2332. In this process, the connecting plate 2331 synchronously drives the four circular plates to move forward. During the movement, the circular plate pulls the three-finger clamp 2323 to make its three clamping ends close synchronously, thereby ensuring that the semicircular cutter 23243 on the same three-finger clamp 2323 fits the insulation of the wire harness. As the conical rod 2332 is continuously pulled, the semicircular cutter 23243 cuts into the insulation of the wire harness and completes the ring cutting of the insulation of the wire harness. At this time, the elastic block provided on the clamping plate 2333 is clamped into the rectangular Inside the clamping groove in the slide 211, the elastic clamping block can realize the precise positioning and reliable limiting of the clamping plate 2333, the connecting plate 2331 and the tapered rod 2332 after being clamped into the preset clamping groove. The integrity of the conductive core is crucial to ensuring the conductive performance of the wiring harness and the reliability of the electrical connection. The limiting work of the elastic clamping block can ensure that after the semicircular cutter 23243 cuts into the insulation layer of the wiring harness, the magnetic rod 113 cannot continue to drive the tapered rod 2332 to move further due to the obstruction of the clamping groove, effectively preventing the semicircular cutter 23243 from over-cutting due to the continuous movement of the tapered rod 2332 after cutting into the insulation layer of the wiring harness, thereby avoiding damage to the conductive core.

[0059] During the wire harness installation process, in order to ensure that the wire harness remains stable during the welding preparation stage and is not disturbed by external forces and causes position displacement, differentiated clamping mechanisms at the front and rear ends are adopted to achieve effective positioning of the wire harness. Through the coordinated clamping strategy at the front and rear ends, a complete positioning system is formed, which can effectively resist the disturbance of external forces and ensure that the wire harness is always in the preset precise position before the welding operation begins, thereby minimizing the risk of reduced welding quality due to wire harness shaking and ensuring the smooth progress of the welding process.

[0060] Wire stripping work of the wire harness:

[0061] After the semicircular cutters 23243 provided on the four three-finger clamps 2323 have synchronously cut into the insulation of the four wire harnesses, the gear shaft 111 continues to rotate and engages the upper and lower racks 112 to move away synchronously (because the tapered rod 2332 is fixedly connected to the clamping plate 2333, so when the elastic block is engaged in the clamping groove and the tapered rod 2332 completes the limit, as the lower rack 112 and the magnetic rod 113 continue to move, the tapered rod 2332 is blocked and disengaged from the magnetic rod 113). The upper rack 112 is magnetically fixed to the magnetic block by the magnetic push block 114 provided above it during the gradual movement (in the initial state, the magnetic push block 114 is set corresponding to the position of the magnetic block, but there is a certain distance between the magnetic push block 114 and the magnetic block. When the lower rack 112 moves by pulling the tapered rod 2332 through the magnetic rod 113, the magnetic push block 114 has not yet magnetically contacted the magnetic block, so the arc slider 2321 will not move), after the magnetic push block 114 is magnetically connected to the magnetic block, the upper rack 112 continuously pushes the arc slider 2321 to move along the arc slide groove 212, and in the process of the movement of the arc slider 2321, the mounting block 2322 arranged thereon synchronously drives the annular plate 23242 and the corresponding semicircular cutter 23243 to move (because the elastic clamping block arranged on the front end clamping plate 2333 is still located inside the clamping groove, the tapered rod 2332 has not moved, so the arc mounting plate 1 23341 and the arc mounting 2 are still in a tightly fitted state, and the matching clamping plate 23345 arranged on the arc mounting plate 1 23341 and the arc mounting plate 2 23342 is used to implement the pressing work on the outer wall of the front end of the wiring harness, ensuring that the rear end will not drive the entire wiring harness to move when pulling the insulation). During the movement of the semicircular cutter 23243, the rear end insulation is pulled out of the wiring harness.

[0062] While the arc-shaped slider 2321 drives the semi-circular cutter 23243 to gradually move, the annular plate 23242 simultaneously pushes the push plate and the annular ring 221 to move. During the movement of the annular ring 221, it pushes the second mounting plate 222 and the round head rod 241 located inside the two annular rings 221 to move. When the second mounting plate 222 moves, it will drive the circular connector installed inside it to move (since the front end of the wire harness is tightly fixed, when the second mounting plate 222 drives the circular connector to move backward, it means that the circular connector moves away from the conductive wire of the wire harness. At the same time, the synchronous movement of the semi-circular cutter 23243 pushes the cut insulation skin onto the semi-circular tube). During the movement of the round head rod 241, the position of the round head rod 241 and the semi-circular tube is gradually changed through the provided arc-shaped groove 223, so that the round head rod 241 drives the U-shaped push plate 242 to deflect and gradually push out the insulation skin inside the U-shaped push plate 242 on the end face of the semi-circular tube and drop it into the lower waste area (since the round head rod 241 is always located inside the arc-shaped groove 223, and the front end of the arc-shaped groove 223 is a straight line segment, and the rear end is an arc segment tangent to the straight line segment, so the round head rod 241 will smoothly transition from the straight line segment to the arc segment during the pushing process, and change the position of the round head rod 241 and the U-shaped push plate 242 through the arc segment). After completing the unloading work of the insulation skin after cutting, the external motor controls the reverse rotation of the gear shaft 111 and drives the upper rack 112 to move in the opposite direction, and during the movement, it drives the semi-circular cutter 23243 and the circular connector to reset, so that the conductive wire is located on the upper surface of the welding terminal of the circular connector. Through the reciprocating movement of the upper rack 112, the synchronous peeling and unloading operations of the insulation layers of the four wire harnesses are realized. Through the design of realizing multiple functions with a single action, not only significantly improves the working efficiency of wire harness insulation skin peeling, simplifies the operation process, but also enhances the coherence and fluency of the welding work. Without frequent switching or adjustment, the insulation skin peeling and unloading tasks of multiple wire harnesses can be continuously completed, thus shortening the welding preparation time and improving the overall production efficiency.

[0063] It should be noted that one end of the semicircular cutter 23243 is fixedly connected to a magnetic boss 23244, and the other end is provided with a U-shaped matching groove. This design allows multiple semicircular cutters 23243 on the same three-finger clamp 2323 to approach each other synchronously and complete the circular cutting task, and the magnetic boss 23244 at one end can be inserted into the U-shaped matching groove on the adjacent cutter. Through the close fit between the magnetic boss 23244 and the U-shaped matching groove, a magnetic connection between adjacent semicircular cutters 23243 is achieved. This connection method not only ensures the reliability of the connection, but also enables all semicircular cutters 23243 on the same three-finger clamp 2323 to be magnetically connected into a stable whole. When the whole moves under the push of the rack 112, this stable connection method can ensure the stability and synchronization of the entire cutter system during the movement, and avoid instability caused by looseness or misalignment between the cutters.

[0064] Welding work between circular connector and wiring harness conductive wire:

[0065] After completing the stripping of the wire harness insulation, the lifting equipment is controlled to drive the welding head to move downward, and the circular connector welding terminal is welded to the wire harness conductive wire by pressure welding. After the welding of a single wire harness is completed, the welding head moves upward and reset, and then the external stepper motor is controlled to drive the annular tube 1 21 and the annular tube 2 22 to rotate synchronously, and after rotating ninety degrees, the welding head is continued to be controlled downward to weld the welding terminal and the conductive wire. The welding work of the circular connector and the wire harness can be completed by repeating this process. Finally, the limiting mechanism is controlled to disengage from the circular connector, and the finished product after welding is taken out from the inside of the annular tube 2 22.

[0066] It is worth emphasizing that the electronic connector welding equipment based on the flattened structure has the following advantages:

[0067] Advantage 1: In order to enhance the overall strength and hardness of the wire harness during installation, there is no need to strip the wire harness before inserting it into the annular tube 21, reducing the risk of bending the wire harness due to gravity or contact with the inner wall of the annular tube 21. After the four wire harnesses complete the limiting work, the reciprocating motion of the rack 112 located above realizes the synchronous stripping and withdrawal operations of the insulation layers of the four wire harnesses. The design of realizing multiple functions through a single action not only significantly improves the efficiency of stripping the insulation of the wire harness, simplifies the operating process, but also enhances the continuity and smoothness of the welding work. Without frequent switching or adjustment, the insulation stripping and withdrawal tasks of multiple wire harnesses can be completed continuously, thereby shortening the welding preparation time and improving the overall production efficiency.

[0068] Advantage 2: the outer wall of the tapered rod 2332 continuously pushes the rectangular matching plate 23344, so that the distance between the arc-shaped mounting plate 2 23342 and the arc-shaped mounting plate 1 23341 gradually decreases, and finally the clamping and limiting work of the outer wall of the wiring harness is completed by the matching clamping plate 23345 provided on the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342. The matching clamping plate 23345 is installed inside the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342 through a spring slide. When the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342 approach each other and work together to achieve the limited clamping of the wiring harness, the spring sliding mechanism can effectively buffer and absorb the action. The U-shaped grooves are formed at both ends of the arc-shaped mounting plate 23341, and correspondingly, the two ends of the arc-shaped mounting plate 23342 are fixedly connected with matching blocks at the positions corresponding to the U-shaped grooves. Therefore, when the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342 are close to each other, the U-shaped grooves and the matching blocks are precisely matched, guiding the distance between the arc-shaped mounting plate 1 23341 and the arc-shaped mounting plate 2 23342 to be further reduced, thereby significantly improving the clamping force on the wire harness and avoiding the wire harness from being offset in different directions by external forces before welding.

[0069] Advantage three: during the movement, the circular plate pulls the three-finger clamp 2323 so that the three clamping ends of the three-finger clamp 2323 are synchronously close, so that the semicircular cutter 23243 located on the same three-finger clamp 2323 fits the insulation skin of the wire harness. As the conical rod 2332 is continuously pulled, the semicircular cutter 23243 cuts into the inside of the insulation skin of the wire harness and completes the circumferential cutting of the insulation skin of the wire harness. The limiting work of the elastic block can ensure that after the semicircular cutter 23243 cuts into the insulation layer of the wire harness, the magnetic rod 113 cannot continue to drive the conical rod 2332 to move further due to the obstruction of the clamping groove, which effectively prevents the semicircular cutter 23243 from over-cutting due to the continuous movement of the conical rod 2332 after cutting into the insulation layer of the wire harness, thereby avoiding damage to the conductive core.

[0070] Advantage four: one end of the semicircular cutter 23243 is fixedly connected to a magnetic boss 23244, and the other end is provided with a U-shaped matching groove. When multiple semicircular cutters 23243 on the same three-finger clamp 2323 approach each other synchronously and complete the circular cutting task, the magnetic boss 23244 at one end can be inserted into the U-shaped matching groove on the adjacent cutter. Through the close fit between the magnetic boss 23244 and the U-shaped matching groove, the magnetic connection between adjacent semicircular cutters 23243 is achieved, which not only ensures the reliability of the connection, but also enables all semicircular cutters 23243 on the same three-finger clamp 2323 to be magnetically connected into a stable whole. When the whole moves under the push of the rack 112, this stable connection method can ensure the stability and synchronization of the entire cutter system during the movement, and avoids instability caused by looseness or misalignment between the cutters.
