Description

Technical Field

[0001] This invention belongs to the technical field of wire harness adhesive application equipment, and relates to an adhesive application device and method for wire harnesses. Background Technology

[0002] Anti-pinch strips are crucial safety components for preventing pinching in electric tailgates and sliding doors. When the anti-pinch strip encounters an obstacle and is squeezed, the first and second conductive layers in the strip separate and then adhere, causing a change in resistance. The electric tailgate ECU detects and identifies this change to determine if the strip is to be pinched. Therefore, the installation of anti-pinch strips is extremely important. In current technology, most anti-pinch strip wiring harnesses need to be attached to the bracket using 3M tape. 3M tape needs to be adhered to the wiring harness with precision and flatness, and it requires a certain amount of pressure. However, current methods are mostly done manually, meaning the 3M tape is manually applied to the anti-pinch strip wiring harness. Manual application cannot guarantee the accuracy of adhesion, and no pressure is applied to the 3M tape after application, failing to achieve the optimal adhesion effect. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an adhesive application device and method that enables pressure retention between the wire harness and the tape and achieves automatic adhesive application to the wire harness.

[0014] In the above-mentioned wire harness adhesive application device, the inner top of the lower frame is provided with an inverted F-shaped mounting bracket.

The upper cylinder and the lower cylinder are not on the same vertical plane, the gripping cylinder and the fourth cylinder are not on the same vertical plane, the plane where the gripping cylinder is located is perpendicular to the plane where the third cylinder is located, and the gripper is located at the end of the third cylinder away from the lower cylinder.

[0016] In the above-mentioned wire harness adhesive application device, the worktable is provided with a boss, and multiple through slots are provided on the top surface of the boss. The worktable is also provided with a work seat.

[0045] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0046] Example 1

[0047] like Figure 1 — Figure 12 As shown, the wire harness adhesive applicator of the present invention includes a lower frame 100, an upper frame 130, a placement mechanism 200, an adhesive storage mechanism 300, a worktable 400, a gripping component 500, a transfer mechanism 600, and a rolling component 700.

[0048] In this invention, the tape located on the workbench 400 is referred to as adhesive tape, and the tape wrapped around the adhesive storage mechanism 300 is referred to as wrapping tape.

[0049] A lower shelf 100 is provided with an upper shelf 130; a placement mechanism 200 is provided on the lower shelf 100, the placement mechanism 200 is used to temporarily store wire harnesses; an adhesive storage mechanism 300 is provided on the lower shelf 100, the adhesive storage mechanism 300 is used to temporarily store adhesive tape; a workbench 400 is provided on the lower shelf 100; a gripping component 500 is provided inside the upper shelf 130, the gripping component 500 grips the adhesive tape in the adhesive storage mechanism 300 and transfers it to the workbench 400; a transfer mechanism 600 is provided inside the upper shelf 130, the transfer mechanism 600 transfers the wire harness on the placement mechanism 200 to the workbench 400 and connects it with the workbench. The tape is stacked on the workbench 400; the rolling assembly 700 is located inside the upper frame 130, and the rolling assembly 700 rolls the tape and wire harness stacked on the workbench 400; the lower frame 100 is provided with a cutting assembly 120, which is located between the glue storage mechanism 300 and the workbench 400. A clamping component 370 is provided on one side of the glue storage mechanism 300. During operation, the wire harness needs to be placed on the placement mechanism 200. At the same time, the gripping assembly 500 grips the wrapping adhesive from the glue storage mechanism 300 to directly above the workbench 400. At this time, the clamping component 370 releases the wrapping adhesive. Subsequently, the clamping component 370 clamps the adhesive, and the clamping component 370 and the gripping component 500 descend simultaneously to place the adhesive on the worktable 400, thus turning the adhesive into a bonding agent. Then, the cutting component 120, located on the lower frame 100, cuts the bonding agent on the side of the clamping component 370 near the gripping component 500, leaving a preset length of adhesive to pass through the cylinder claw 372 for the next gripping by the gripping component 500. Afterward, the gripping component 500 releases the bonding agent and rises, and the clamping component 370 also returns to its original position and rises. Following this, the transfer mechanism 600 grips the wire harness on the placement mechanism 200. The wire harness is placed on the worktable 400 and overlapped with the adhesive tape on the worktable 400 to allow for initial adhesion. Subsequently, the rolling assembly 700 rolls the tape and wire harness stacked on the worktable 400. After rolling, the transfer mechanism 600 transfers the rolled tape and wire harness from the worktable 400. In this way, the tape application of the wire harness can be automated, eliminating the need for manual application of tape to the wire harness. This effectively improves the tape application efficiency, reduces labor costs, and ensures that the tape and wire harness have a certain holding pressure during the adhesion process, thus guaranteeing the success rate of tape application.

[0050] like Figure 2 — Figure 5As shown, the transfer mechanism 600 includes a first cylinder plate 610 movable relative to the upper frame 130 and a transfer cylinder 620 installed at the top of the upper frame 130. The first cylinder plate 610 can be raised and lowered relative to the transfer cylinder 620, and the transfer cylinder 620 can drive the first cylinder plate 610 to move in a specific direction. The first cylinder plate 610 is provided with a plurality of second cylinders 630, and each second cylinder 630 is equipped with a claw 640. A transfer seat 650 is slidably installed on the transfer cylinder 620, and the transfer seat 650 is provided with a first cylinder 660 that drives the first cylinder plate 610 to rise and fall. During the transfer of the wire harness, the first cylinder plate 610 must first be transferred to the top of the placement mechanism 200 by the transfer cylinder 620, so that each claw 640 is positioned directly above the wire harness. After that, the first cylinder 660 drives the first cylinder plate 610 to move in a specific direction. The first cylinder 610 and the second cylinder 630 descend until the wire harness is located in the middle of the jaw 640. Then, the second cylinder 630 controls the jaw 640 to clamp the two sides of the wire harness. The first cylinder 660 then drives the second cylinder 630 to rise. Then, the transfer cylinder 620 can drive the first cylinder 660, transfer seat 650, first cylinder plate 610, second cylinder 630, jaw 640 and wire harness to move synchronously relative to the upper frame 130. That is, the wire harness moves towards the worktable 400. When the wire harness reaches the top of the worktable 400, the first cylinder 660 drives the first cylinder plate 610 to descend so that the wire harness can smoothly reach the worktable 400. Then, the jaw 640 releases, the first cylinder plate 610 rises, and after the wrapping adhesive is pasted on the wire harness, the jaw 640 transfers the wire harness and wrapping adhesive together from the worktable 400.

[0051] The placement mechanism 200 includes a placement plate 210 mounted on a lower frame 100, a placement rack 220 mounted on the placement plate 210, and placement blocks 230 spaced apart on the placement rack 220, arranged in a straight line. The placement plate 210 also has at least two placement seats 240, each located on the extension line of the straight line containing the placement blocks 230. The top surface of each placement block 230 is flush with the top of the placement seat 240. A plurality of clamping components 800 are provided on one side of the placement plate 210. During operation, the wire harness needs to be placed into the slots of the placement blocks 230. The excess portion of the wire harness is placed in the groove of the placement seat 240. Then, the clamping assembly 800 will press the wire harness into the groove of the placement block 230 to prevent the wire harness from bending during the clamping process of the claw 640 or during normal placement. When the claw 640 clamps the wire harness, the claw 640 will hold the wire harness through the gap between the two placement blocks 230. Furthermore, the position of the claw 640 on the first cylinder plate 610 is offset from the placement seat 240 to prevent the claw 640 from colliding with the placement seat 240 during the descent.

[0052] Each of the clamping assemblies 800 includes a clamping seat 810 connected to the placement plate 210 and a clamping plate 820 rotatable relative to the clamping seat 810. The clamping seat 810 is equipped with a clamping cylinder 830 that drives the clamping plate 820 to rotate. The clamping cylinder 830 is equipped with a clamping rod 840 hinged to one end of the clamping plate 820. A connecting block 850 is hinged to the clamping seat 810 and hinged to the middle of the clamping plate 820. When the clamping assembly 800 is in the open state, both the clamping seat 810 and the clamping plate 820 are perpendicular to the connecting block 850; that is, the clamping plate 820 can be vertically upwards at this time. When the clamping assembly 800 needs to press... When handling the wire harness, simply control the clamping cylinder 830 so that the clamping rod 840 rises relative to the clamping cylinder 830. At the same time, the connecting block 850 will rotate relative to the clamping seat 810. During this process, the clamping plate 820 will also rotate adaptively relative to the connecting block 850. When the connecting block 850 and the clamping seat 810 are on the same plane, the clamping plate 820 will continue to rotate relative to the connecting block 850 until the clamping plate 820 and the connecting block 850 are perpendicular. At this time, the clamping cylinder 830 stops working, and the clamping plate 820 will also press the wire harness into the groove of the placement block 230 to prevent the wire harness from bending in the placement block 230.

[0053] A handle 860 is provided on the top of the clamping plate 820. When the clamping cylinder 830 fails, people can manually open the clamping plate 820 through the handle 860.

[0054] like Figure 6 — Figure 7 and Figure 11 — Figure 12 As shown, the lower frame 100 has an inverted F-shaped mounting bracket 110 at its inner top, and the gripping component 500 and the rolling component 700 are both mounted on the mounting bracket 110.

[0055] The gripping assembly 500 includes a lower cylinder 510 mounted on a mounting bracket 110, a lower slider 520 slidably mounted on the lower cylinder 510, a gripping cylinder 530 mounted on the lower slider 520, a second cylinder plate 540 movably mounted on the gripping cylinder 530, a third cylinder 550 mounted on the second cylinder plate 540, and a gripper 560 movably mounted on the third cylinder 550. The gripping cylinder 530, through the second cylinder plate 540, drives the third cylinder 550 and the gripper 560 to rise and fall relative to the lower slider 520. When the gripper 560 grips the end of the tape, the lower cylinder 510 moves the lower slider 520, thus moving the gripper 560 relative to the lower cylinder 510, allowing the gripper 560 to grip the wrapped tape. The adhesive is pulled out from the adhesive storage mechanism 300 until the wrapping adhesive is directly above the worktable 400. Then, the gripping cylinder 530 pushes the second cylinder plate 540 down so that the third cylinder 550, the gripper 560 and the wrapping adhesive descend synchronously, so that the tape can be smoothly placed on the worktable 400. After the adhesive is cut, the third cylinder 550 controls the gripper 560 to release the adhesive. Then, the gripping cylinder 530 can drive the second cylinder plate 540, the third cylinder 550 and the gripper 560 to rise. When the second cylinder plate 540 rises to the initial height, the lower cylinder 510 drives the lower slider 520 to return to the end of the lower cylinder 510 close to the adhesive storage mechanism 300, in preparation for gripping the end of the next section of wrapping adhesive.

[0056] The workbench 400 is provided with a boss 410, and a plurality of through slots 411 are provided on the top surface of the boss 410. The through slots can be used to pass through the claws. The workbench 400 is also provided with a work seat 420. The slots on the boss 410 (not marked in the figure) can be used to place adhesive and wire harness. The work seat 420 is used to temporarily place the excess part of the adhesive and the excess part of the wire harness.

[0057] The rolling assembly 700 includes an upper cylinder 710 mounted on a mounting bracket 110, an upper slider 720 slidably mounted on the upper cylinder 710, a fourth cylinder 730 mounted on the upper slider 720, and a rolling seat 740 movably mounted on the fourth cylinder 730. The rolling seat 740 is provided with at least two rollers 750. The fourth cylinder 730 can drive the rolling seat 740 to rise and fall relative to the upper cylinder 710. When the gripping cylinder 530 drives the second cylinder plate 540 and the third... After the cylinder 550 and gripper 560 rise to their initial positions and the transfer mechanism 600 has placed the wire harness on the worktable 400, the fourth cylinder 730 drives the rolling seat 740 to descend until the roller 750 presses against the top surface of the wire harness and exerts a certain squeezing force on the wire harness, so that there is a certain pressure between the wire harness and the adhesive. After that, the upper cylinder 710 drives the upper slider 720 to move back and forth once, which can ensure a better bonding effect between the wire harness and the adhesive.

[0058] The stroke length of the upper slider 720 is only the length of the boss 410. That is, the roller 750 can only roll from one end of the boss 410 to the other end of the boss 410 and will not exceed the range of the boss 410, so as to avoid the rolling assembly 700 doing useless work. Furthermore, the number of rollers 750 can be at least two. In this way, when the upper slider 720 moves in one direction relative to the upper cylinder 710, the two rollers 750 can roll the wire harness at the same time, thereby effectively improving the rolling effect of the wire harness. After the rolling process is completed, the fourth cylinder 730 drives the rolling seat 740 to rise until the top of the rolling seat 740 abuts against the fourth cylinder 730.

[0059] The upper cylinder 710 and the lower cylinder 510 are not on the same vertical plane, and the gripping cylinder 530 and the fourth cylinder 730 are not on the same vertical plane. The plane of the gripping cylinder 530 is perpendicular to the plane of the third cylinder 550, and the gripper 560 is located at the end of the third cylinder 550 away from the lower cylinder 510. Thus, when the gripping cylinder 530 moves with the sliding block 520 and passes the fourth cylinder 730, the gripping cylinder 530 and the fourth cylinder 730 will not come into contact. Furthermore, when the top of the rolling seat 740 abuts against the fourth cylinder 730 and the gripping cylinder 530 passes the fourth cylinder 730, since the bottom of the rolling seat 740 is higher than the height of the third cylinder 550 at this time, and the gripper 560 is located at the end of the third cylinder 550 away from the lower cylinder 510, the rolling seat 740 and the third cylinder 550 will not come into contact, so that the gripping assembly 500 can move smoothly to the end of the lower cylinder 510 near the glue storage mechanism 300.

[0060] The adhesive storage mechanism 300 includes an adhesive base 310 movable relative to the lower frame 100. An adhesive plate 320 is provided on the adhesive base 310, and a adhesive tray 330 for storing winding adhesive is mounted on the adhesive plate 320. A base plate 340 is provided on the lower frame 100, and a slide rail 350 slidably connected to the adhesive base 310 is provided on the base 340. A rod seat 311 is provided on the adhesive base 310, and a screw 360 is threaded through the rod seat 311. At least two adjusting seats 360 are provided on the base plate 340 for movably mounting the screw 360. 41. Before operation, the screw 360 can be rotated according to the operational requirements, so that the screw 360 drives the rod seat 311 and the glue seat 310 to move along the track of the slide rail 350. Since the glue plate 320 is set on the glue seat 310, the glue plate 320 also moves synchronously. In this way, the boss 410 and the glue tray 330 can be located in the same vertical plane, so that after the wrapping glue on the glue tray 330 is pulled out by the gripping component 500, the wrapped glue pulled out is exactly above the boss 410.

[0061] The clamping component 370 includes a fixed cylinder 371 movably mounted on the side of the adhesive plate 320 facing the worktable 400. A movable claw 372 is mounted on the fixed cylinder 371. A lifting cylinder 373, which drives the fixed cylinder 371 to rise and fall, is provided on one side of the adhesive plate 320. When the wrapping adhesive is pulled out by the claw 560, the fixed cylinder 371 controls the claw 372 to clamp the wrapping adhesive. At this time, the end of the wrapping adhesive is clamped by the claw 560, thus tightening the pulled-out wrapping adhesive. Furthermore, when the lifting cylinder... When the body 373 lowers the fixed cylinder 371 and the cylinder claw 372, the gripper 560 also lowers at the same time until the pulled-out wrapping adhesive is placed on the boss 410. After that, the cutting component 120 cuts the end of the adhesive near the cylinder claw 372 and leaves a preset length of adhesive tape to pass through the cylinder claw 372 for the gripper 560 of the gripping component 500 to grip next. Then, the lifting cylinder 373 raises the fixed cylinder 371 to the initial position, waiting for the gripper 560 to grip the preset length of wrapping adhesive again.

[0062] The cutting assembly 120 includes a push cylinder 121 mounted on the lower frame 100, a push seat 122 movably mounted on the push cylinder 121, and a cutting cylinder 123 mounted on the push seat 122. A scissor 124 is movably mounted on the cutting cylinder 123. The moving direction of the push seat 122 is parallel to the normal direction of the adhesive plate 320. When the cylinder claw 372 and the gripper 560 clamp the adhesive and lower it until the adhesive remains on the worktable 400, the cutting cylinder 123 controls the scissors 124 to open. Afterward, the push cylinder 121 drives the push seat 122 to move. When the opening of the scissors 124 touches the adhesive, the push cylinder 121 stops working, and simultaneously, the cutting cylinder 123 drives the scissors 124 to close. Thus, the scissors 124 can cut the adhesive. Then, the push cylinder 121 returns to its original position, ready for the next cut.

[0063] Example 2

[0064] like Figure 1 — Figure 12 As shown, this embodiment is the adhesive application method of the adhesive application device in Embodiment 1.

[0065] Specifically, one method of applying adhesive includes the following steps:

[0066] Step 1: The wire harness needs to be placed on the placement block 230 of the placement mechanism 200, and the excess part of the wire harness is placed on the placement seat 240. After that, the clamping assembly 800 presses the clamping plate 820 on the placement block 230 to prevent the wire harness from being completely inside the slot of the placement block 230, and also to prevent the wire harness from being completely inside when the claw 640 of the transfer mechanism 600 grabs the wire harness.

[0067] Step 2: While Step 1 is being performed, the gripper 560 of the gripping component 500 holds the pre-reserved length of the wrapping adhesive on the cylinder claw 372. Then, the cylinder claw 372 is released, and the gripper 560 pulls out the wrapping adhesive and drags it directly above the worktable 400. After that, the cylinder claw 372 holds the wrapping adhesive again.

[0068] Step 3: Cylinder claw 372 and clamping claw 560 descend simultaneously until the wrapping adhesive between cylinder claw 372 and clamping claw 560 is placed on the worktable 400;

[0069] Step 4: The push cylinder 121 drives the push seat 122 to move, and when the opening of the scissors 124 touches the adhesive, the push cylinder 121 stops working. At the same time, the cutting cylinder 123 drives the scissors 124 to close. In this way, the scissors 124 can cut the adhesive near the end of the cylinder claw 372 and leave a preset length of tape to pass through the cylinder claw 372 for the next gripping by the gripper 560. After that, the gripper 560 releases the tape and is lifted by the first cylinder 660. The lifting cylinder 373 also drives the cylinder claw 372 to reset and rise.

[0070] Step 5: The jaws 640 of the transfer mechanism 600 clamp the wire harness on the placement block 230. At the same time, the clamping plate 820 of the clamping assembly 800 flips and no longer clamps the wire harness. After that, the jaws 640 rises and are driven by the transfer cylinder 620 to move towards the worktable 400.

[0071] Step 6: The transfer cylinder 620 transfers the wire harness to the top of the worktable 400, and the first cylinder 660 drives the wire harness to descend until the wire harness is placed on the worktable 400 and overlapped with the tape on the worktable 400. Then, the chuck 640 releases the wire harness and rises.

[0072] Step 7: The rollers 750 of the rolling assembly 700 roll the tape and wire harness stacked on the worktable 400 to ensure that there is pressure between the adhesive and the wire harness, thereby ensuring that the adhesive and the wire harness can be better bonded together.

[0073] Step 8: The jaws 640 of the transfer mechanism 600 descend and clamp the rolled adhesive and wire harness, and then transfer the adhesive and wire harness from the worktable 400.

[0074] The above-described adhesive application method not only enables the adhesive to be automatically applied to the wire harness, but also ensures that there is pressure between the adhesive and the wire harness, so as to ensure that the adhesive and the wire harness can be better bonded together.
