Description

Technical Field

[0001] This utility model belongs to the field of wire harness processing technology, and in particular relates to a tape wrapping and bundling mechanism. Background Technology

[0002] In the wire harness manufacturing process, longer cables need to be coiled and bundled to ensure neatness, ease of handling, and reduced interference during production. Currently, the mainstream coil bundling method is adhesive tape bundling, which offers advantages such as a neat and aesthetically pleasing appearance, low production cost, environmental friendliness, and convenient disassembly in subsequent processes.

[0003] However, existing adhesive tape bundling mechanisms on the market have many problems: some mechanisms use single-sided or step-by-step double-sided bundling, resulting in easy bundling scattering or long processing times; some mechanisms achieve bundling by sticking the adhesive sides of the tape together, making the coil bundling weak and prone to loosening during production; some mechanisms have inaccurate positioning, preventing the tape from accurately adhering to the coil, resulting in a high failure rate and unstable quality; at the same time, existing mechanisms generally suffer from long bundling action sequences, low efficiency, complex mechanisms, and high equipment costs. Therefore, there is an urgent need for an adhesive tape wrapping mechanism that can solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an adhesive tape wrapping mechanism that achieves secure coil wrapping, simultaneous operation on both sides, accurate positioning, improved efficiency, and reduced costs, thereby solving the problems of the prior art.

The coil positioning component is used to position the coil to be wrapped. The tape application component includes a tape wrapping mechanism that can move circumferentially around the coil to wrap tape around the coil. The tape application and transfer component is drivenly connected to the tape application component and is used to drive at least two sets of tape application components to synchronously approach or move away from the coil, so that at least two sets of tape application components can simultaneously wrap tape around different parts of the coil.

[0007] Preferably, the coil positioning assembly includes a coil gripper and a wire end gripper; the coil gripper is used to clamp and fix the main body of the coil to be bundled; the wire end gripper is used to clamp the wire end portion of the coil to be bundled.

[0008] Preferably, the adhesive-applying transplanting assembly includes a transplanting drive and a transmission belt; the transplanting drive is driven to connect with the transmission belt, and at least two sets of adhesive-applying assemblies are respectively fixed at different positions on the transmission belt. The transplanting drive drives the transmission belt to rotate in both directions, thereby causing at least two sets of adhesive-applying assemblies to move synchronously closer to or further away from the coil.

[0009] Preferably, the transplanting drive is a servo motor; the transmission belt is a synchronous belt.

[0010] Preferably, the adhesive tape winding mechanism includes a winding drive, a transmission timing belt, an open gear, and a timing belt tensioner; the winding drive is driven to the transmission timing belt, and the transmission timing belt partially wraps around the open gear via a timing belt idler pulley, so that the open gear can rotate with the transmission timing belt; the timing belt tensioner is used to tension the transmission timing belt.

[0011] Preferably, the synchronous belt tensioner is a spring block; the winding drive is a winding servo driver.

[0012] Preferably, the adhesive application assembly further includes an adhesive paper pulling claw mechanism, which includes a claw drive, a claw transmission component, and an adhesive paper pulling claw; the claw drive drives the adhesive paper pulling claw to perform opening and closing movements through the claw transmission component to clamp the adhesive paper, and can also drive the adhesive paper pulling claw to perform linear movements to pull the adhesive paper.

[0013] Preferably, the gripper drive includes a gripper transfer servo motor and a gripper cylinder; the gripper transmission component is a synchronous belt; the gripper transfer servo motor drives the synchronous belt to rotate forward and backward, thereby driving the adhesive-pulling gripper to perform up-and-down linear motion; the gripper cylinder drives the adhesive-pulling gripper to perform opening and closing motion by extending and retracting.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention discloses an adhesive tape wrapping mechanism. By setting at least two sets of adhesive application components, in conjunction with an adhesive application and transfer component, it achieves synchronous approach / remote movement towards the coil. This allows for simultaneous adhesive tape wrapping of different parts of the coil, avoiding the scattering problems caused by single-sided or step-by-step wrapping, and significantly improving efficiency through synchronous operation. The adhesive tape wrapping mechanism of the adhesive application component can move circumferentially around the coil, achieving multi-turn tight wrapping of the adhesive tape, solving the problems of weak and loose wrapping in existing technologies. A synchronous belt drive combined with spring pressure blocks ensures smooth and stable operation of the adhesive tape wrapping mechanism, improving positioning accuracy and reducing the failure rate. The mechanism passively pulls the adhesive tape through an adhesive tape gripper mechanism, reducing the need for components such as adhesive tape roller drives and conveyor servo motors, thus lowering equipment costs. The coil positioning component and the adhesive application component work closely together, and the adhesive tape pulling and preparation actions can be completed simultaneously during the coil loading and unloading process, saving production time and further improving efficiency.

[0026] like Figure 1 As shown, the adhesive tape wrapping and bundling mechanism of this embodiment includes a coil positioning assembly, two sets of adhesive application assemblies (left adhesive application assembly 101 and right adhesive application assembly 102), and an adhesive application and transplanting assembly 104. The coil positioning assembly includes coil grippers 103 and wire end grippers 105. The coil grippers 103 are used to clamp and fix the main body of the coil to be bundled, and four are provided to ensure stable positioning. The wire end grippers 105 are used to clamp the wire end of the coil to prevent the wire end from interfering with the bundling. The adhesive application and transplanting assembly 104 is equipped with a servo motor (transplanting drive) that drives a synchronous belt (transmission belt) to rotate forward and backward. The upper and lower edges of the synchronous belt are respectively fixed to the left adhesive application assembly 101 and the right adhesive application assembly 102. When the servo motor rotates forward, it drives the two sets of adhesive application assemblies to move towards the center to get closer to the coil; when it rotates backward, it drives the two sets of adhesive application assemblies to move to both sides to get away from the coil.

[0027] like Figure 1 As shown, both the left adhesive application assembly 101 and the right adhesive application assembly 102 include, for example, an adhesive tape winding mechanism, an adhesive tape pulling gripper mechanism, and an adhesive tape cutting mechanism. Figure 2 As shown, the adhesive tape winding mechanism includes a winding servo drive 201 (winding drive component), a transmission synchronous belt 202, a synchronous belt idler pulley open gear 204, and a spring pressure block (synchronous belt tensioner, not shown in the figure); the winding servo drive 201 drives the transmission synchronous belt 202 to rotate, and the transmission synchronous belt 202 partially wraps around the open gear 204 through the synchronous belt idler pulley 203, so that the open gear 204 follows the synchronous belt to rotate; the spring pressure block tensions the transmission synchronous belt 202 to ensure smooth operation of the open gear 204.

[0028] like Figure 3 As shown, the adhesive paper pulling gripper mechanism includes a gripper transfer servo motor 301 (gripper drive), a synchronous belt 302 (gripper transmission), an adhesive pulling gripper 30, and a gripper cylinder 304 (gripper drive); the gripper transfer servo motor 301 drives the adhesive pulling gripper 303 connected to the synchronous belt 302 to move up and down by forward and reverse rotation, and the gripper cylinder 304 drives the adhesive pulling gripper 303 to open and close by extension and retraction to grip or release the adhesive paper.

[0029] like Figure 4 As shown, the adhesive tape cutting mechanism includes a cutter base 401, an adhesive tape cutter 402, a needle-type cylinder 403, an adhesive tape idler wheel 404, an adhesive tape presence / absence detection sensor 405, a cutter shaft 406, an adhesive tape cutting cylinder 407 (cutting drive component), a cutter connecting rod 408, an adhesive tape pressing rubber band 409 (adhesive pressing component), and a rubber band connecting plate 410. The needle-type cylinder 403, the adhesive tape idler wheel 404, the adhesive tape presence / absence detection sensor 405, and the cutter shaft 406 are fixed on the cutter base 401; the adhesive tape presence / absence detection sensor 405 detects whether the adhesive tape is used up; the adhesive tape idler wheel 404 guides the adhesive tape transport; and the needle-type cylinder 403 presses down on the adhesive tape to prevent it from being accidentally pulled. The cutter shaft 406 is fixedly connected to the cutter connecting rod 408, and the adhesive tape cutting cylinder 407 is hinged to the cutter connecting rod 408. The cutter shaft 406 is also fixedly connected to the adhesive tape cutting blade 402. When the adhesive tape cutting cylinder 407 extends or retracts, it rotates the cutter shaft 406, thereby causing the adhesive tape cutting blade 402 to swing and cut the adhesive tape. The adhesive tape pressing rubber band 409 is fixed on the rubber band connecting plate 410 and fixedly connected to the open gear 204. It moves with the open gear 204 to press the adhesive tape against the coil.

[0030] Specifically, the working principle of this technical solution is as follows:

[0031] 1. The adhesive tape passes through the adhesive tape idler wheel 404 and is inserted between the cutter base 401 and the needle cylinder 403. The gripper transfer servo motor 301 of the adhesive tape gripper mechanism drives the adhesive tape gripper 303 to move up to above the adhesive tape cutter. The gripper cylinder 304 pushes out to close the adhesive tape gripper 303 and clamp the head of the adhesive tape. Then the gripper transfer servo motor 301 drives the adhesive tape gripper 303 to move down to pull out the adhesive tape of the preset length.

[0032] 2. The coil to be bundled is placed in the coil positioning assembly. The coil clamp 103 closes to clamp the coil body, and the wire end clamp 105 closes simultaneously to clamp the wire end.

[0033] 3. The servo motor of the adhesive application and transfer component 104 rotates forward, driving the left and right adhesive application components to move towards the center to the position to be applied, so that the coil presses the adhesive surface of the adhesive paper and embeds into the center of the open gear 204, and the adhesive paper pressing rubber band 409 partially wraps the adhesive paper around the coil.

[0034] 4. The adhesive tape cutting cylinder 407 of the adhesive tape cutting mechanism extends, driving the adhesive tape cutting blade 402 to swing and close to cut the adhesive tape;

[0035] 5. The adhesive gripper 303 opens, and the winding servo drive 201 of the adhesive wrapping mechanism drives the transmission synchronous belt 202 to rotate, so that the open gear 204 and the adhesive paper pressure rubber band 409 rotate with the synchronous belt, and wrap the adhesive paper around the coil multiple times in the circumferential direction until the preset length of adhesive paper is used up.

[0036] 6. The servo motor of the adhesive application and transplanting component 104 reverses, driving the left and right adhesive application components to the standby position. The coil clamp 103 and the wire end clamp 105 open synchronously, and the bundled coil is taken away.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
