Description

Technical Field

[0001] This invention belongs to the field of wire harness assembly technology, and more specifically, relates to an automatic assembly equipment for multi-specification automotive wire harness terminals. Background Technology

[0002] Currently, in the automotive industry, a large number of connecting wires are often needed inside the car to connect the various components of the equipment and the main control board of the equipment. During the processing of automotive wiring harnesses, a lot of rubber sleeves and terminals are assembled on the wiring harness. At present, terminal crimping and rubber sleeve assembly are mainly done manually.

[0003] The operator places the portion of the wire harness with the insulation removed onto the clamping part of the terminal. The terminal cutter moves downward to crimp and clamp the wire harness and the terminal, thus completing the crimping and clamping of the wire harness and the terminal, and thus completing the cyclical continuous work. Chinese utility model patent CN213034017U discloses an assembly equipment for automotive wire harness terminals and rubber sleeves. The terminal feeding vibratory plate and the rubber sleeve feeding vibratory plate are respectively set on both sides of the frame. The terminal assembly station is set in the middle of the frame. The roller wire harness conveying device is set in front of the terminal assembly station. The rubber sleeve blowing assembly device is set between the assembly station and the roller wire harness conveying device. The robot arm is installed between the terminal feeding vibratory plate and the terminal assembly station and between the rubber sleeve feeding vibratory plate and the rubber sleeve blowing assembly device. The terminal crimping device is set directly above the assembly station.

[0004] While this equipment can connect the rubber sleeve and terminals to the automotive wiring harness, the existing method of manually inserting and pressing the terminals onto the ends of the wiring harness makes it impossible to precisely control the insertion depth. If the wiring harness is inserted too deeply, the contact area between the terminal and the insulation will be too large, reducing the effective crimping area between the terminal and the copper wire, thus increasing the contact resistance and potentially causing the terminal to overheat or burn. If the wiring harness is inserted too shortly, the contact area between the terminal and the insulation will be too small, resulting in insufficient tensile strength between the terminal and the wiring harness, making it prone to loosening during actual use. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] To address the problems in the existing technology where terminals are manually crimped onto the ends of automotive wiring harnesses, which results in unpredictable insertion depth, excessive insertion leads to an excessively large contact area between the terminal and insulation, reducing the effective crimping area between the terminal and the copper wire, thus increasing contact resistance and potentially causing overheating or burning of the terminal; conversely, insufficient insertion reduces the contact area between the terminal and insulation, resulting in insufficient tensile strength and easy loosening during actual use, this invention adopts the following technical solution.

[0007] One objective of this invention is to provide an automatic assembly equipment for automotive wiring harness terminals of various specifications, including a worktable, a terminal mold mounted on the worktable, a terminal cutter that can move up and down on the terminal mold, a feeding claw on the terminal mold, an assembly block detachably connected below the terminal cutter, a first pressure roller rotatably connected to the upper part of the inner side of the two side assembly brackets, and a second pressure roller rotatably connected to the lower part of the inner side of the two side assembly brackets, with a rotating shaft fixedly connected to both ends of the first and second pressure rollers, and the rotating shaft rotatably connected to the assembly brackets, the rotating shaft on one side of the first pressure roller passing through the assembly bracket, a limit plate being provided at the end of the rotating shaft passing through, and a positioning plate being provided on the outer wall of the assembly bracket near the limit plate, the first pressure roller being fixed when the first pressure roller rotates, causing the rotating shaft to drive the limit plate to rotate, and the limit plate contacting the positioning plate.

[0008] In the above technical solution, through the design of the first pressure roller and the second pressure roller, when the wire harness passes through the arc grooves on both sides, the first pressure roller and the second pressure roller rotate simultaneously. The rotation of the first pressure roller causes the rotating shaft to drive the limiting plate to rotate. During the rotation, the limiting plate contacts the positioning plate, which can restrict the first pressure roller so that it cannot rotate.

[0009] Based on this, a rotating block is rotatably connected to the end of the rotating shaft, and a fastening bolt is threadedly connected to the outside of the rotating block. The fastening bolt is threadedly connected to the end of the rotating shaft, and the limiting plate is fixedly connected to the outer wall of the rotating block.

[0010] In the above technical solution, by designing a rotating shaft and fastening bolts, loosening the fastening bolts allows the limiting plate to rotate via the rotating block, thereby changing its position relative to the positioning plate.

[0011] Based on this, an annular measuring tool is provided on the outside of the side of the assembly bracket where the rotating shaft passes through. The diameter of the annular measuring tool is the same as the diameter of the first pressure roller, and the center of the annular measuring tool coincides with the center of the rotating shaft. The annular measuring tool is provided with a length scale mark, which corresponds to the length of the wire harness fed in by the first pressure roller when the limit plate rotates and contacts the positioning plate.

[0012] In the above technical solution, the limit plate can be precisely adjusted through the design of the ring gauge and scale markings.

[0013] Based on this, the inner wall of the ring gauge is provided with an inner groove, the end of the limiting plate is inserted into the inner groove of the ring gauge, and the outer wall of the limiting plate is fixedly connected with an indicator arrow pointing to the scale mark.

[0014] In the above basic scheme, the design of the limiting plate insertion groove and the indicator arrow makes it easier to observe whether the adjustment position of the limiting plate matches the wire feeding distance of the wire harness.

[0015] In another technical solution, through slots are provided on the outer sides of the assembly bracket, and sliding blocks are slidably connected inside the through slots on both sides. Rotating shafts on both sides pass through the sliding blocks, and sliding rods protruding from the assembly bracket are fixedly connected to the upper ends of the sliding blocks on both sides. Linkage plates are fixedly connected to the protruding ends of the sliding rods on both sides. A connecting horizontal plate is fixedly connected between the upper ends of the two assembly brackets on both sides. Adjusting bolts are rotatably connected to the connecting horizontal plate. The adjusting bolts are threadedly connected to the linkage plates. Rotating the adjusting bolts causes the linkage plates on both sides to drive the sliding rods on both sides to move up and down.

[0016] In the above technical solution, rotating the adjusting bolt causes the two side linkage plates to move up and down, thereby driving the two side sliding rods to move up and down through the sliding block.

[0017] Based on this, the positioning plate is internally telescopically connected to a sliding plate with scale markings. The mounting bracket is fixedly connected to a second semicircular plate near the lower outer wall. The sliding block is fixedly connected to a first semicircular plate. The sliding plate and the second semicircular plate are detachably connected to each other. The positioning plate and the first semicircular plate are detachably connected. The positioning plate and the first semicircular plate overlap near the lower outer wall.

[0018] In the above technical solution, the design of the sliding plate allows for quick and precise adjustment by observing the scale markings on the sliding plate when adjusting the up and down movement of the first pressure roller.

[0019] In another technical solution, the outer wall at the center of the first pressure roller and the second pressure roller is provided with an arc-shaped groove, and the wire harness passes through the two arc-shaped grooves on the first pressure roller and the second pressure roller and is inserted into the terminal.

[0020] In the above technical solution, the arc-shaped groove design can limit the insertion of the wire harness, preventing the wire harness from being unable to be inserted into the terminal after passing through.

[0021] Based on this, the annular measuring tool is detachably connected to the outer wall of the first semicircular plate, and the annular measuring tool moves with the first pressure roller.

[0022] Based on this, the second semicircular plate and the second pressure roller have the same diameter and overlap, and the first semicircular plate and the first pressure roller have the same diameter and overlap.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when the wire harness passes through the arc-shaped grooves on both sides, the first pressure roller and the second pressure roller rotate simultaneously. The rotation of the first pressure roller causes the rotating shaft to drive the limiting plate to rotate. During the rotation, the limiting plate contacts the positioning plate, which restricts the first pressure roller from rotating, thereby enabling precise control of the insertion depth of the wire harness. By loosening the fastening bolts, the limiting plate can be rotated by the rotating block, thereby changing its position relative to the positioning plate. This allows for adjustment of the wire harness insertion depth when facing different wire harnesses or terminals. When adjusting the limiting plate, the wire harness feeding depth can be precisely adjusted by observing the scale markings on the outer wall of the annular measuring tool indicated by the indicator arrow. This allows for quick adjustment of the wire harness insertion depth when facing different requirements of different wire harnesses or terminals, ensuring consistency of terminals on each wire harness.

[0024] 2. In this invention, rotating the adjusting bolt causes the two side linkage plates to move up and down, which in turn drives the two side sliding rods to move up and down through the sliding block, thereby allowing the rotating shaft and the first pressure roller to move up and down. This allows the distance between the first pressure roller and the second pressure roller to be adjusted according to the diameter of the wire harness. When adjusting the up and down movement of the first pressure roller, the adjustment can be made quickly and accurately by observing the scale markings on the sliding plate, making the adjustment faster and more efficient.

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1-3 The diagram shows a preferred embodiment of an automatic assembly equipment for multi-specification automotive wiring harness terminals. This embodiment includes a workbench 100, on which a terminal mold 101 is mounted. The terminal mold 101 has a vertically movable terminal cutter 102 and a feeding claw 103. An assembly block 104 is detachably connected to the lower part of the terminal cutter 102. In this embodiment, the stripped end of the wiring harness is placed below the terminal cutter 102 and inserted into the terminal. A pressing component on the workbench 100 drives the terminal cutter 102 to fall and connect the terminal to the end of the wiring harness. When the terminal cutter 102 rises, the feeding claw 103 conveys the terminal forward, thus enabling continuous terminal pressing operations.

[0030] like Figure 4As shown, this is a schematic diagram of the wire feeding assembly installation structure in this embodiment. The upper ends of the assembly block 104 are detachably connected to the assembly brackets 202 on both sides. The upper part of the inner side of the assembly brackets 202 is rotatably connected to the first pressure roller 200, and the lower part of the inner side of the assembly brackets 202 is rotatably connected to the second pressure roller 201. The outer wall of the center of the first pressure roller 200 and the second pressure roller 201 is provided with an arc groove 203. The wire harness passes through the two arc grooves 203 on the first pressure roller 200 and the second pressure roller 201 and is inserted into the terminal. In this embodiment, passing the wire harness through the arc grooves 203 on both sides can limit the left and right position of the wire harness, so as to prevent the wire harness from being unable to be inserted into the terminal. When the wire harness passes through, the first pressure roller 200 and the second pressure roller 201 rotate with it, which can prevent the insulation of the wire harness from rubbing against other components and causing cracks, and can also prevent scratches on the outer wall of the insulation.

[0031] By rotating the first pressure roller 200 or the second pressure roller 201 to a certain position and then fixing it, the insertion distance of the wire harness can be precisely positioned. To achieve this, the specific structure can be as follows: Figure 5 as well as Figure 6 In the embodiment shown, the first pressure roller 200 and the second pressure roller 201 are fixedly connected to two ends of a rotating shaft 205. The rotating shaft 205 is rotatably connected to the assembly bracket 202. The rotating shaft 205 on one side of the first pressure roller 200 extends out of the assembly bracket 202. A limit plate 208 is provided at the end of the rotating shaft 205 extending out of the first pressure roller 200. A positioning plate 204 is provided on the outer wall of the assembly bracket 202 near the limit plate 208. The rotation of the first pressure roller 200 causes the rotating shaft 205 to drive the limit plate 208 to rotate. After contacting the positioning plate 204, the first pressure roller 200 is fixed. In this embodiment, when the wire harness passes through the arc-shaped grooves 203 on both sides, the first pressure roller 200 and the second pressure roller 201 rotate simultaneously. The rotation of the first pressure roller 200 causes the rotating shaft 205 to drive the limit plate 208 to rotate. During the rotation, the limit plate 208 contacts the positioning plate 204 to restrict the first pressure roller 200 from rotating. For specific posture reference... Figure 7 This allows for precise control of the insertion depth of the wire harness. By changing the position of the limiting plate 208 or the positioning plate 204, the wire harness can be positioned at different insertion depths.

[0032] Due to the different wire harnesses and terminal specifications, the insertion depth of the wire harness varies. In order to accurately control the insertion depth to meet the different requirements of wire harness insertion depth, the specific implementation method can be as follows: Figure 6In the embodiment shown, a rotating block 206 is rotatably connected to the end of the rotating shaft 205, and a fastening bolt 207 is threadedly connected to the outside of the rotating block 206. The fastening bolt 207 is threadedly connected to the end of the rotating shaft 205, and the limiting plate 208 is fixedly connected to the outer wall of the rotating block 206. In this embodiment, by loosening the fastening bolt 207, the limiting plate 208 can be rotated by the rotating block 206, thereby changing the position between it and the positioning plate 204. This allows for adjustment of the wire harness entry depth when facing different wire harnesses or terminals, making it more widely applicable.

[0033] In order to accurately determine the relationship between the position of the positioning plate 208 and the positioning plate 204 and the wire harness entry depth, so as to precisely control the wire harness entry depth when adjusting the position of the positioning plate 208, the specific implementation method can be as follows: Figure 6 In the illustrated embodiment, an annular measuring tool 210 is provided on the outside of the side of the mounting bracket 202 where the rotating shaft 205 protrudes. The diameter of the annular measuring tool 210 is the same as the diameter of the first pressure roller 200, and the center of the annular measuring tool 210 coincides with the center of the rotating shaft 205. An inner groove is provided on the inner wall of the annular measuring tool 210. The end of the limiting plate 208 is inserted into the inner groove of the annular measuring tool 210. A length scale mark is provided on the annular measuring tool 210. When the limit plate 208 rotates and contacts the positioning plate 204, the first pressure roller 200 drives the wire harness to feed in for a certain length. An indicator arrow 209 pointing to the scale mark is fixedly connected to the outer wall of the limiting plate 208. In this embodiment, when adjusting the limiting plate 208, the wire harness feeding depth can be precisely adjusted by observing the indicator arrow 209 pointing to the scale mark on the outer wall of the annular measuring tool 210. This allows for quick adjustment of the wire harness feeding depth when facing different requirements of different wire harnesses or different terminals, ensuring consistency of terminals on each wire harness.

[0034] Different wire harnesses have different specifications, and therefore different diameters. To enable the feeding of wire harnesses of different diameters, the following specific implementation method can be adopted: Figure 8 as well as Figure 9In the embodiment shown, the assembly bracket 202 has through slots 211 on both sides of its exterior. Sliding blocks 303 are slidably connected inside the through slots 211 on both sides. Rotating shafts 205 on both sides pass through the sliding blocks 303. Sliding rods 302 protruding from the assembly bracket 202 are fixedly connected to the upper ends of the sliding blocks 303 on both sides. Linkage plates 300 are fixedly connected to the protruding ends of the sliding rods 302 on both sides. A connecting horizontal plate 212 is fixedly connected between the upper ends of the two assembly brackets 202 on both sides. An adjusting bolt 301 is rotatably connected to the connecting horizontal plate 212. The adjusting bolt 301 is threadedly connected to the linkage plate 300. In this embodiment, by rotating the adjusting bolt 301, the linkage plates 300 on both sides drive the sliding rods 302 on both sides to move up and down. This allows the rotating shafts 205 and the first pressure roller 200 to move up and down through the sliding blocks 303. Thus, the distance between the first pressure roller 200 and the second pressure roller 201 can be adjusted according to the diameter of the wire harness.

[0035] When adjusting the distance between the first pressure roller 200 and the second pressure roller 201, in order to achieve quick and accurate adjustment, the specific implementation method can be as follows: Figure 9 as well as Figure 10 In the embodiment shown, a sliding measuring plate 306 is internally telescopically connected to the positioning plate 204. The sliding measuring plate 306 is provided with scale markings. A second semicircular plate 305 is fixedly connected to the outer wall of the mounting bracket 202 near its lower end. The second semicircular plate 305 has the same diameter as and coincides with the diameter of the second pressure roller 201. A first semicircular plate 304 is fixedly connected to the outer wall of the sliding block 303. The first semicircular plate 304 has the same diameter as and coincides with the diameter of the first pressure roller 200. The outer walls of the sliding measuring plate 306 and the second semicircular plate 305 are detachably connected. The positioning plate 204 is detachably connected to the first semicircular plate 304. The outer walls of the positioning plate 204 and the first semicircular plate 304 near its lower end coincide. In this embodiment, when adjusting the up and down movement of the first pressure roller 200, quick and accurate adjustment can be achieved by observing the scale markings on the sliding measuring plate 306, making the adjustment faster and more efficient.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
