Description

Technical Field

[0001] This utility model relates to the technical field of wire harness production, and in particular to an automatic soldering equipment for wire harness terminals. Background Technology

[0002] Wire harnesses are accessories used to achieve electrical connections. Currently, the common practice for welding terminals and wire harnesses is to crimp the terminals and wire harness together, followed by welding by technicians using welding heads. Most systems now utilize welding machines for both crimping and welding. However, the stripping of the wire harness and the welding of the wire harness to the terminals still require technician intervention, increasing the probability of wire harness damage and the accuracy of the connection between terminals and wire harnesses. Therefore, there is an urgent need for efficient and precise automated wire harness welding equipment. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automatic soldering equipment for wire harness terminals, which has the characteristics of high production efficiency and high degree of automation.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] An automatic soldering device for wire harness terminals includes: a workbench; a wire harness conveying device for conveying wire harnesses, including a conveyor belt extending along the length of the workbench and a plurality of support plates disposed on the conveyor belt for carrying the wire harnesses; a wire harness stripping device mounted on the workbench and located on one side of the wire harness conveying device, the wire harness stripping device including a stripping mechanism vertically mounted on the workbench and a wire pressing mechanism mounted on the stripping mechanism; the stripping mechanism including a mounting frame vertically mounted on the workbench, a stripping knife assembly disposed on the mounting frame facing the conveyor belt, and a first drive unit disposed on the mounting frame for driving the stripping knife assembly; a soldering device disposed downstream of the wire harness stripping device along the wire harness conveying direction, including a main support vertically mounted on the workbench, a soldering mechanism mounted on the main support and reciprocating along its height direction, a feeding mechanism slidably disposed on the main support for feeding terminals, and a storage mechanism parallel to the movement direction of the feeding mechanism and disposed on the main support; the soldering mechanism includes a sliding plate and a solder head connected to each other and reciprocating along the vertical direction.

[0006] To achieve the above technical solution, the wire harness stripping device and the soldering device are sequentially set on the same side of the wire harness conveying device along the wire harness feeding direction. The upstream wire harness stripping process is realized, and the downstream terminal soldering process is realized. No technical personnel are required, which improves the automation level of the equipment.

[0007] Furthermore, the mounting frame includes a mounting plate vertically mounted on the workbench and a fixed plate parallel to the workbench, mounted on the mounting plate and on which the first drive unit is installed; the peeling knife assembly includes a lower knife assembly mounted on the side of the fixed plate facing the conveyor belt and an upper knife assembly connected to the output end of the first drive unit and facing the conveyor belt; the upper knife assembly is connected to the output end of the first drive unit through a top plate.

[0008] To achieve the above technical solution, the upper blade assembly is connected to the output end of the first drive unit, and the reciprocating motion of the output end of the first drive unit is used to realize the opening and closing between the upper blade assembly and the lower blade assembly, that is, to strip the skin of each branch of the wire harness.

[0009] Furthermore, a storage box is also provided on the fixing plate; the storage box is located between the lower blade assembly and the first drive unit, and has an opening on the side facing the lower blade assembly.

[0010] To achieve the above technical solution, the waste material stripped from the wire harness is collected by a storage box facing the lower blade assembly, preventing it from accumulating on the workbench.

[0011] Furthermore, the wire pressing mechanism includes a fixed frame mounted on the top plate and a wire pressing plate mounted on the fixed frame and facing the conveyor belt; the bearing plate has wire harness grooves and wire pressing grooves arranged perpendicularly to each other, and the wire pressing plate and the wire pressing grooves are arranged correspondingly.

[0012] To achieve the above technical solution, the relative arrangement of the pressure plate and the pressure groove ensures that the pressure plate can accurately press the part that does not need to be peeled each time it is pressed down, and ensures that the part that needs to be peeled at the front end can be peeled stably.

[0013] Furthermore, the feeding mechanism includes a guide plate that slides horizontally on the main support and a terminal clamp that extends from the guide plate toward the solder head; the guide plate is parallel to and fitted with the sliding plate, and a guide groove is formed on it; at least partially slidable guide posts are installed on the sliding plate and accommodated in the guide groove.

[0014] To achieve the above technical solution, the vertical displacement of the sliding plate is converted into the front-back displacement of the guide plate and the terminal clamp by the movement of the guide post in the guide groove.

[0015] Furthermore, the storage mechanism includes a support plate parallel to the workbench and mounted on the main support, a telescopic cylinder arranged along the length of the support plate, and a storage box located at the front end of the telescopic cylinder; the storage box has a through hole for accommodating terminals and for the telescopic rod to pass through; the telescopic rod of the telescopic cylinder passes through the through hole and is positioned opposite to the solder head; the terminals are clamped between the storage box and the solder head and move back and forth.

[0016] To achieve the above technical solution, the telescopic mechanism pushes the terminal out of the storage box, and the terminal clamp, which moves back and forth between the storage box and the solder head, receives it.

[0017] Furthermore, it also includes a terminal feeding device, including a material rack on the workbench, a vibrating plate on the material rack, and a terminal slide that extends from the vibrating plate to the storage box and then to the storage trough to feed the terminals.

[0018] As described above, the automatic soldering equipment for wire harness terminals of this utility model has the following beneficial effects:

[0019] 1. In this utility model, the movement of the guide post on the sliding plate in the guide groove allows the reciprocating motion of the sliding plate in the vertical direction to synchronously drive the reciprocating motion of the terminal clamp between the solder head and the storage box, ensuring that the soldering work and the terminal feeding action can always be consistent, and ensuring the stability of the equipment operation.

[0020] 2. The pressure plate structure is placed on the top plate of the peeling mechanism, so that the upper blade assembly and the pressure plate can press down simultaneously, ensuring the stability of the peeling blade assembly; at the same time, the equipment structure is optimized, making the whole more compact and occupying less space.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0029] Please see Figure 1-6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0030] Please see Figures 1 to 6This utility model provides an automatic soldering device 1000 for wire harness terminals, including a workbench 1 and a wire harness conveying device 2, a stripping device, and a soldering device 4 disposed on the workbench 1. The wire harness stripping device 3 and the soldering device 4 are sequentially arranged on the same side of the wire harness conveying device 2 along the wire harness conveying direction. The wire harness conveying device 2 includes a conveyor belt 21 extending along the length direction of the workbench 1 and a plurality of support plates 22 disposed on the conveyor belt 21 for carrying the wire harness.

[0031] Please continue reading. Figures 2 to 3 The wire harness stripping device 3 includes a stripping mechanism 31 vertically mounted on the workbench 1 and a wire pressing mechanism 32 mounted on the stripping mechanism 31. The stripping mechanism 31 includes a mounting frame 311 vertically mounted on the workbench 1, a stripping blade assembly 312 mounted on the mounting frame 311 facing the conveyor belt 21, and a first drive unit 313 mounted on the mounting frame 311 for driving the stripping blade assembly 312.

[0032] Specifically, the mounting frame 311 includes a mounting plate 3111 vertically mounted on the workbench 1 and a fixing plate 3112 parallel to the workbench 1, mounted on the mounting plate 3111 and on which the first drive unit 313 is mounted. The stripping knife assembly 312 includes a lower knife assembly 3121 mounted on the fixing plate 3112 facing the conveyor belt 21 and an upper knife assembly 3122 connected to the output end of the first drive unit 313 and facing the conveyor belt 21. The upper knife assembly 3122 is connected to the first drive unit 313 via a top plate 314. The first drive unit 313 drives the upper knife assembly 3122 to move up and down, realizing the opening and closing between the upper knife assembly 3122 and the lower knife assembly 3121, thereby realizing the wire harness stripping process.

[0033] Furthermore, the wire pressing mechanism 32 includes a fixing frame 321 mounted on the top plate 314 and a wire pressing plate 322 mounted on the fixing frame 321 and facing the conveyor belt 21. By placing the fixing frame 321 of the wire pressing mechanism 32 on the top plate 314 of the stripping mechanism 31, the wire pressing plate 322 and the upper blade assembly 3122 can press down simultaneously, meaning that while stripping the wire harness, the wire pressing plate 322 can press down on the wire harness. Preferably, the wire pressing mechanism also includes an elastic member mounted on the fixing frame 321 and connected to the wire pressing plate 322, ensuring that the wire pressing plate 322 does not damage the unstripped portion of the wire harness, provided that the wire pressing plate 322 can abut against the wire harness.

[0034] It should be noted that the support plate 22 has wire harness grooves 221 and wire pressing grooves 222 arranged perpendicularly to each other, and the wire pressing plate 322 is correspondingly arranged with the wire pressing grooves 222. The design of the wire harness grooves 221 and wire pressing grooves 222 effectively avoids the problem of interference between the wire pressing plate 322 and the support plate 22, so that the wire pressing plate 322 can stably press the wire harness on the support plate 22 each time it is pressed down, ensuring the orderly progress of the subsequent stripping process.

[0035] Furthermore, the fixed plate 3112 is also equipped with a storage box 315, which is located between the lower blade assembly 3121 and the first drive unit 313. The storage box 315 has an opening 3151 on the side facing the lower blade assembly 3121. The storage box 315 is used to collect the waste material stripped from the wire harness, so that the waste material will not accumulate on the worktable 1, ensuring the stable operation of the equipment.

[0036] Please continue reading. Figure 4 The soldering device 4 includes a main support 41 mounted on a vertical worktable 1, a soldering mechanism 42 mounted on the main support 41 and reciprocating along its height direction, a feeding mechanism 43 slidably mounted on the main support 41 for feeding terminals, and a storage mechanism 44 parallel to the movement direction of the feeding mechanism 43 and mounted on the main support 41.

[0037] Specifically, the soldering mechanism 42 includes a sliding plate 421 and a solder head 422 that are interconnected and reciprocate vertically, as well as a second drive unit 423 for driving the sliding plate 421. It should be noted that a solder wire feeding mechanism 45 for supplying solder wire to the solder head 422 is also provided on the side of the main support 41 away from the soldering mechanism 42.

[0038] The feeding mechanism 43 includes a guide plate 431 horizontally slidably mounted on the main support 41 and a terminal clamp 432 extending from the guide plate 431 towards the solder head 422. The guide plate 431 is parallel to and fitted to the sliding plate 421. A guide groove 4311 is formed on the guide plate 431, and a guide post 4221, at least partially slidably accommodated within the guide groove 4311, is mounted on the sliding plate 421. By utilizing the sliding displacement of the guide post 4221 within the guide groove 4311, when the second drive unit 423 drives the sliding plate 421 to perform a vertical reciprocating motion, the terminal clamp 432 connected to the guide plate 431 moves horizontally back and forth along the main support 41. This ingenious structure ensures that the feeding action of the terminal clamp 432 and the welding action of the solder head remain synchronized, greatly improving the stability of the welding process.

[0039] Furthermore, the storage mechanism 44 includes a support plate 441 parallel to the workbench 1 and mounted on the main support 41, a telescopic cylinder 442 arranged along the length of the support plate 441, and a storage box 443 located at the front end of the telescopic cylinder 442. The storage box 443 has a through hole 4431 for accommodating terminals and through which the telescopic rod 4221 passes. The telescopic rod 4221 of the telescopic cylinder 442 passes through the through hole 4431 and is positioned opposite to the solder head 422. The terminal clamp 432 moves between the storage box 443 and the solder head 422. By setting the storage box 443 at the front end of the telescopic cylinder 442 and cooperating with the telescopic rod 4221 of the telescopic cylinder 442 to push out the terminals in the storage box 443, which are then received by the terminal clamp 432, the terminals are transferred from the storage box 443 to below the solder head.

[0040] In addition, such as Figure 6 As shown, a clamping plate 23 is vertically provided on the side of the bearing plate 22 facing the wire harness stripping device 3. The clamping plate 23 is used to fix each branch wire in the wire harness, which facilitates the stripping of the stripped straight wires and also facilitates the subsequent insertion of each straight wire into the terminal and soldering.

[0041] In addition, please continue to refer to Figure 1 An automatic soldering device 1000 for wire harness terminals also includes a feeding device, which includes a material rack 51 on a workbench 1, a vibrating plate 52 on the material rack 51, and a terminal slide 53 extending from the vibrating plate 52 to the storage box 443 and to the storage trough to deliver terminals.

[0042] The implementation principle of the automatic welding equipment for wire harness terminals in this utility model is as follows: The wire harness conveying device 2 transfers the wire harness from the external device to the bearing plate 22, and the conveyor belt 21 transports the wire harness downstream; when the wire harness passes the wire harness stripping device 3, the first drive unit 313 drives the top plate 314 to descend, which in turn drives the upper blade group 3122 and the wire pressing plate 322 to descend simultaneously. The wire pressing plate 322 presses the wire harness, and the upper blade group 3122 and the lower blade group 3121 contact and close to strip the exposed branches on the wire harness. The removed waste enters the storage box 315 through the opening 3151; then the wire harness continues to descend. In the downstream conveyor, when the wire harness passes the soldering device 4, the terminals from the vibrating plate enter the storage box 443 and are pushed out by the telescopic rod 4221. The terminals are then received by the terminal clamp 432. The second drive unit 423 drives the sliding plate 421 and the solder head 422 to move downward in the vertical direction. The guide plate 431 drives the terminal clamp 432 to move closer to the solder head 422 as the sliding plate 421 moves, until the exposed branch wire can be inserted into the terminal and soldered by the solder head 422. Finally, the conveyor belt 21 continues to move the wire harness carrying the soldered terminals downstream, thus completing the entire process of automated wire harness terminal soldering.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
