Abstract
Description
Technical Field
[0001] This invention relates to the field of wire harness manufacturing, specifically to the field of wire harness terminal crimping, and further to a terminal bevel feeding crimping method and apparatus. Background Technology
[0002] In the automotive wiring harness manufacturing industry, the existing terminal crimping process involves cutting the terminal strip to obtain terminal strip units with terminals. Then, the strip is fed through a feeding mechanism. Each time the strip is fed, a pair of strip clamps clamp both ends of the terminal strip unit and convey it to the crimping mechanism. In the existing method, the strip clamps do not hold the ends of the strip firmly, which makes it difficult to increase the number of terminals fed in a single operation. That is, the more terminals fed in a single operation, the heavier the weight, and the more difficult it is to maintain the clamping force between the strip clamps and the ends of the strip.
[0003] Currently, only one terminal is fed at a time. After crimping, the feeding mechanism repeatedly returns to pick up and feed the terminal. The round trip time of the feeding mechanism is relatively long, and the crimping mechanism needs to wait for a long time. The time spent on the terminal feeding process has become a bottleneck to improving the efficiency of the crimping operation. Summary of the Invention
[0004] Therefore, the present invention provides a terminal bevel feeding crimping method and apparatus, which aims to solve how to improve the clamping stability of the material strip clamp and the end of the material strip.
[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows: A terminal bevel feeding crimping method includes the following steps: S1 provides terminal strips; S2, the terminal strip is cut by oblique cutting, that is, the cutting direction is inclined to the length direction of the strip; to obtain a terminal strip unit with at least one terminal; S3, clamps both ends of the terminal strip unit with a pair of strip clamps and crimps them for feeding; S4, crimp the terminals of the terminal strip unit onto the wire harness.
[0006] Furthermore, in step S2, the terminal strip is cut into groups of at least two terminals to obtain a terminal strip unit with at least two terminals. In step S4, at least two terminals of the terminal strip unit are sequentially crimped onto the same group of processed wire harnesses.
[0007] Furthermore, in step S2, a tilted blade is used to cut the terminal strip sequentially.
[0008] Furthermore, in step S2, the last terminal strip unit in the terminal strip is first clamped by a transfer clamp, and then the strip is cut to obtain an independent terminal strip unit.
[0009] Furthermore, the transfer clamp is held in the middle of the terminal strip unit, and then the transfer clamp transfers the terminal strip unit to a pair of strip clamps, which respectively clamp both ends of the terminal strip unit.
[0010] A terminal beveling feeding crimping device includes: Tape output mechanism, used to output terminal tape; The cutting mechanism cuts the terminal strip by oblique cutting, i.e., the cutting direction is inclined to the length of the strip; thus obtaining a terminal strip unit with at least one terminal. The feeding mechanism has a pair of strip clamps, which clamp the two ends of the strip of the terminal strip unit and feed it to the crimping mechanism. The crimping mechanism sequentially crimps the two terminals of the terminal strip unit, which is fed by the feeding mechanism, onto the wire harness.
[0011] Furthermore, it also includes a transfer mechanism, which is disposed between the cutting mechanism and the feeding mechanism. The transfer mechanism has a transfer clamp that holds the terminal strip unit and transports the terminal strip unit to the feeding mechanism.
[0012] Furthermore, the transfer clamp of the transfer mechanism is held on the strip between the two terminals of the terminal strip unit. When transferred to the feeding mechanism, a pair of strip clamps of the feeding mechanism respectively clamp the two ends of the strip of the terminal strip unit.
[0013] Furthermore, the feeding mechanism also includes a translation driver, which drives a pair of strip clamps to translate the strip clamps and the terminal strip unit, thereby causing the two terminals of the terminal strip unit to sequentially correspond to the crimping end of the crimping mechanism.
[0014] The technical solution provided by this invention has the following beneficial effects: 1. The terminal strip is beveled to obtain a terminal strip unit with at least one terminal and the end face of the strip is beveled. This can extend the length of the strip, so that a pair of strip clamps of the feeding mechanism can stably and reliably clamp both ends of the terminal strip unit, thereby effectively improving the clamping stability between the strip clamps and the ends of the strip.
[0015] 2. Building upon point 1, further, the terminal strip is cut into groups of at least two terminals to obtain a terminal strip unit with at least two terminals; the improved clamping stability of the strip clamp and the end of the strip enables better clamping of terminal strip units with more terminals, achieving stable one-time delivery of multiple terminals, reducing terminal feeding time, effectively shortening the crimping operation interval, and improving crimping efficiency.
[0016] 3. Furthermore, at least two terminals of the terminal strip unit are sequentially crimped onto the same set of processed wire harnesses. In this way, the feeding mechanism's back-and-forth feeding and wire harness switching are synchronized. That is, one feeding trip of the feeding mechanism is coordinated with one set of processed wire harnesses. After the crimping is completed, the wire harness is removed, and the feeding mechanism returns to pick up the next terminal strip unit. This ensures good coordination and further shortens the waiting time for crimping operations, thereby improving crimping efficiency. Attached Figure Description

These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0021] Reference Figures 1 to 3 As shown, this embodiment provides a terminal bevel feeding crimping method, which includes the following steps: S1, provides terminal strip 1; such as Figure 1 As shown, the terminal strip 1 consists of a long strip 2 and dozens or hundreds of terminals 3 connected to the strip 2, with the terminals 3 spaced apart along the length of the strip 2.
[0022] S2, the terminal strip 1 is cut into strip 2 by means of a bevel cut, i.e., the cutting direction is inclined to the length direction of the strip 2; thus, a terminal strip unit 11 with at least one terminal 3 is obtained; as in this embodiment, the terminal strip 1 is cut into strip 2 in groups of two terminals 3 to obtain... Figure 2 The terminal strip unit 11 shown has two terminals 3, wherein the strip 2 is cut at an angle, that is, the cutting direction is inclined to the length direction of the strip 2; as shown Figure 1 As shown, at the end of the terminal strip 1, two terminals 3 are grouped together and obliquely cut along the oblique cutting line I using an inclined blade, and this operation is repeated; after cutting, the result is as shown. Figure 2 The terminal strip unit 11 shown has two terminals 3. The cut surface 22 of the strip 2 of the terminal strip unit 11 is inclined, which can effectively increase the length of the strip 2 of each terminal strip unit 11, which is equivalent to exchanging the width dimension of the strip 2 for the length dimension.
[0023] S3, refer to Figure 3 As shown, a pair of tape clamps 41 clamp the two ends of the tape 2 of the terminal tape unit 11 respectively and perform crimping feeding; when the tape clamp 41 clamps the end of the tape 2, that is, clamps the tape part located outside the terminal 3, since the length of the tape 2 of the terminal tape unit 11 is increased, the tape clamp 41 can stably and reliably clamp the end of the tape 2 of the terminal tape unit 11, and will not become unstable due to the increase in the number of terminals 3 (which also increases the weight), thus achieving reliable transmission feeding.
[0024] S4, sequentially crimp the two terminals 3 of the terminal strip unit 11 onto the wire harness.
[0025] This technology enables the stable one-time feeding of two terminals 3, reducing the feeding time of terminals 3. Compared with the feeding of a single terminal 3 in the prior art, it can save the time of one round trip feeding for every two crimping operations, effectively shortening the crimping operation interval and improving the crimping operation efficiency.
[0026] In a further preferred embodiment, the two terminals 3 of the terminal strip unit 11 are sequentially crimped to the same group of processed wire harnesses. In this way, the back-and-forth feeding of the terminal 3 and the switching of the wire harness are synchronized. For example, if one feeding of the terminal 3 is coordinated with two wire harnesses processed in the same group, after the crimping is completed, the gap when the wire harness is removed is simultaneously filled with one back-and-forth feeding of the terminal, which has good coordination; it further shortens the waiting time of the crimping operation and improves the efficiency of the crimping operation.
[0027] Furthermore, such as Figure 4 As shown, to ensure stable cutting and transmission of the terminal strip unit 11, in step S2, the last terminal strip unit 11 of the terminal strip 1 is first clamped by a transfer clamp 31. Specifically, the transfer clamp 31 clamps the strip 2 between the two terminals 3 of the terminal strip unit 11. Then, the strip 2 is cut to obtain an independent terminal strip unit 11. After cutting, the transfer clamp 31 transfers the terminal strip unit 11 to a pair of strip clamps 41, which clamp the two ends of the strip 2 of the terminal strip unit 11 respectively. In this way, stable transmission of the terminal strip unit 11 from cutting to feeding is achieved.
[0028] Continue to refer to Figure 5 and Figure 6 As shown, this embodiment also provides a terminal beveling feeding and crimping device for implementing the above-mentioned terminal beveling feeding and crimping method; specifically, the terminal beveling feeding and crimping device includes a strip output mechanism 100, a cutting mechanism 200, a feeding mechanism 400, and a crimping mechanism 500. The strip output mechanism 100 is used to output the terminal strip 1. Specifically, the strip output mechanism 100 includes a tray and a feeding component. The tray is used to hold the rolled terminal strip 1, and the feeding component outputs the terminal strip 1. Specifically, the structure and cooperation relationship of the tray and the feeding component are prior art and will not be described in detail here.
[0029] The cutting mechanism 200 is located at the output end of the strip output mechanism 100. It cuts the terminal strip 1 into groups of two terminals 3, resulting in a terminal strip unit 11 with two terminals 3. The cutting method for the strip 2 is oblique cutting, meaning the cutting direction is inclined to the length direction of the strip 2. Specifically, the cutting mechanism 200 has an inclined blade, meaning the blade is inclined to the output direction of the strip output mechanism 100, that is, inclined to the length direction of the strip 2 of the terminal strip 1 output by the strip output mechanism 100. Figure 1As shown, at the end of the terminal strip 1, two terminals 3 are grouped together and obliquely cut along the oblique cutting line I using the blade, and this operation is repeated; after cutting, the result is as shown. Figure 2 The terminal strip unit 11 shown has two terminals 3. The cut surface 22 of the strip 2 of the terminal strip unit 11 is inclined, which can effectively increase the strip length of each terminal strip unit 11, which is equivalent to exchanging the width dimension of the strip 2 for the length dimension.
[0030] The feeding mechanism 400 has a pair of feed belt clamps 41, such as Figure 3 As shown, a pair of tape clamps 41 clamp the two ends of the tape 2 of the terminal tape unit 11 and convey it to the crimping mechanism 500. When the tape clamp 41 clamps the end of the tape 2, that is, clamps the tape portion located outside the terminal 3, the tape 2 is lengthened, so that the tape clamp 41 can stably and reliably clamp the end of the tape 2 of the terminal tape unit 11. It will not become unstable due to the increase in the number of terminals 3 (which also increases the weight), thus achieving reliable transmission and feeding.
[0031] The crimping mechanism 500 crimps the two terminals 3 of the terminal strip unit 11, which is fed by the feeding mechanism 400, onto the wire harness in sequence.
[0032] In this way, two terminals 3 can be stably fed at one time, reducing the feeding time of terminals 3. Compared with the feeding of a single terminal 3 in the prior art, the time for one round trip feeding can be saved for every two crimping operations, which can effectively shorten the crimping operation interval and improve the crimping operation efficiency.
[0033] Specifically, since the two terminals 3 of the terminal strip unit 11 are distributed left and right, when one terminal 3 is aligned with the crimping end of the crimping mechanism 500, the other terminal 3 is offset. Therefore, the feeding mechanism 400 also includes a translation driver, which drives a pair of strip clamps 41 to translate left and right. Figure 7 As shown, the translation driver first moves the tape clamp 41 left and right so that the right terminal 3 is aligned with the crimping end of the crimping mechanism 500, and the crimping mechanism 500 crimps the right terminal 3 first; after the right terminal 3 is crimped, the translation driver drives the tape clamp 41 and the terminal tape unit 11 to move to the left, and after the translation, as shown... Figure 8 As shown, at this time, the left terminal 3 is aligned with the crimping end of the crimping mechanism 500, and the crimping mechanism 500 crimps the left terminal 3.
[0034] Furthermore, this embodiment also includes a transfer mechanism 300, which is disposed between the cutting mechanism 200 and the feeding mechanism 400. The transfer mechanism 300 has a transfer clamp 31, which clamps the terminal strip unit 11 and conveys the terminal strip unit 11 to the feeding mechanism 400. Specifically, the transfer clamp 31 of the transfer mechanism 300 clamps the strip 2 between the two terminals 3 of the terminal strip unit 11, such as... Figure 4 As shown; when transferred to the feeding mechanism 400, a pair of tape clamps 41 of the feeding mechanism 400 respectively clamp the two ends of the tape 2 of the terminal tape unit 11. In this way, the terminal tape unit 11 is stably transported from cutting to feeding.
[0035] In the above embodiments, the length of the end of the material strip 2 is increased by oblique cutting, thereby enhancing the clamping reliability between the material strip clamp 41 and the end of the material strip 2. The solution of this application is described in detail with the example of dual-terminal feeding (i.e., the terminal material strip unit 11 has two terminals 3). Of course, in other embodiments, the number of terminals on the terminal material strip unit 11 is not limited to this. The terminal material strip unit 11 can also be a single terminal 3. Alternatively, based on achieving stable clamping and feeding, the number of terminals 3 of the terminal material strip unit 11 can be further increased, such as to three or four.
[0036] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
