Description

Technical Field

[0001] This utility model relates to a wire end processing device, and more particularly to a tape wrapping device. Background Technology

[0002] Twisted-pair cables are generally made of two wires twisted together at a specific pitch. They offer some interference resistance, improve wire flexibility, and reduce the risk of breakage. Furthermore, the twisted wire structure enhances the wire's abrasion and corrosion resistance, extending its lifespan. In practical applications, taking automotive electronics as an example, twisted-pair cables are essential for modules such as engine crankshaft sensors, radios, ABS systems, and CAN bus lines. With the rapid development of automotive electronics and the increasingly widespread application of modular devices and CAN bus technologies, the number of twisted-pair circuits is also increasing. It is important to note that during the wire twisting process, the twist pitch and the final twisted dimensions are two crucial parameters that need to be controlled.

[0003] In existing technologies, twisted pairs of wires will automatically loosen after being left for a certain period of time, and the twist pitch will increase, resulting in a longer twisted cable length. Simultaneously, the twisted pair's resistance to signal interference will weaken. To improve this issue, the industry typically uses adhesive tape to spot-wrap the twisted nodes of the wires to prevent them from unwinding due to natural loosening, which would cause changes in the twist pitch and twisted cable length. Currently, the industry generally uses a manual spot-wrapping method. This involves first cutting the adhesive tape into certain lengths using an adhesive tape cutter, and then manually wrapping the tape around the twisted wire. This method has disadvantages such as low spot-wrapping efficiency, high labor waste, and difficulty in ensuring consistent spot-wrapping positions. Utility Model Content

The lifting and lowering end of the top material assembly is provided with a top material block, and the end of the adhesive tape extends to the top material block. The top material assembly is used to drive the top material block to rise so that the end of the adhesive tape is pasted to the bottom of the twisted pair at the spot winding station. The applicator assembly is provided on the top material block. The moving end of the applicator assembly is provided with an applicator flipping block. The applicator flipping block is hinged to the end of the top material block. The applicator assembly is used to drive the applicator flipping block to flip at a preset angle, so that the end of the adhesive tape is pasted to the side of the twisted pair by the applicator flipping block. The pressing assembly is provided on the cutting and pressing assembly. The lifting and lowering end of the pressing assembly is provided with a pressing block. The pressing block is located above the top material block. The pressing assembly is used to drive the pressing block to fall, so that the end of the adhesive tape is pressed tightly to the twisted pair by the clamping of the pressing block and the top material block.

[0007] Preferably, the unloading assembly includes an L-shaped slider that slides in cooperation with the translation slide mechanism and an unloading drive cylinder for driving the L-shaped slider to slide. The vertical end of the L-shaped slider is provided with a tape mounting shaft, and the tape is fitted onto the tape mounting shaft.

[0008] Preferably, the top of the top material block has a plurality of straight-line adsorption holes, the top material block has a negative pressure channel communicating with the adsorption holes, and the outer side of the top material block has a suction kit for generating negative pressure airflow. The suction kit is connected to the negative pressure channel, and the adhesive tape is adsorbed onto the top material block by the negative pressure in the adsorption holes.

[0009] Preferably, a throttling valve is provided between the air intake end of the suction kit and the negative pressure channel, and the throttling valve is fixed on the top material block.

[0010] Preferably, the top of the top material block is provided with a tape guide groove, the tape is disposed in the tape guide groove, and a plurality of adsorption holes are located at the bottom of the tape guide groove.

[0011] Preferably, the top of the top material block is provided with two guide wheels, which are located above the adhesive tape guide groove, and the guide wheels are used to confine the adhesive tape within the adhesive tape guide groove.

[0012] Preferably, the moving end of the material application assembly is provided with a material application top block, and the material application flipping block includes a flipping block body. The flipping block body is connected to the front end of the top block via a first pin hinge near the middle position. The front end of the flipping block body is provided with a material application stop block. The material application stop block is located on the front side of the top block and there is a gap between the two. The rear end of the flipping block body is connected to the front end of the material application top block via a second pin hinge.

[0013] Preferably, the bottom end of the pressing block is formed with pressing teeth.

[0014] Preferably, the cutting and pressing assembly includes a cutting cylinder, which drives the two cutting motion arms to move closer or further away simultaneously, and the two cutters are respectively fixed on the two cutting motion arms.

[0015] The adhesive tape application device disclosed in this utility model, during operation, first uses the supporting lifting assembly to drive the lifting platform to rise to a preset height position. Then, the conveying assembly drives the translation slide mechanism to move forward, thereby causing the unloading assembly, the top-loading assembly, the applicator assembly, the pressing assembly, and the cutting and pressing assembly on the translation slide mechanism to move closer to the application station until the twisted pair cable is located between the top-loading assembly and the pressing block. Then, the adhesive application action is performed, driven by the top-loading assembly. The top material block is raised, and the end of the adhesive tape is pasted onto the bottom of the twisted pair at the spot winding station via the top material block. Then, side adhesive is applied. The adhesive tape flipping block is driven by the adhesive tape application assembly to rotate at a preset angle, and the end of the adhesive tape is pasted onto the side of the twisted pair via the adhesive tape flipping block. The adhesive tape is then pressed firmly, and the pressure block is driven by the pressure assembly to descend. Based on the clamping of the pressure block and the top material block, the end of the adhesive tape is firmly attached to the twisted pair. Finally, the top material assembly and the pressure assembly retract to their original positions. The upward rotating twisting mechanism that holds the twisted pair drives the twisted pair to rotate. During the rotation of the twisted pair, the adhesive tape is wrapped around the twisted node at the end of the twisted pair, thus completing the first point-wrapping action. Then, the conveying assembly drives the translation slide mechanism to move backward, and the adhesive tape on the unwrapping assembly is unwrapped for the first time. Then, the unwrapping assembly drives the adhesive tape to move backward along the translation slide mechanism to perform the second unwrapping action. Finally, the cutting and pressing assembly drives the two cutters to move towards each other. The device moves and cuts the adhesive tape between the two ends, while simultaneously using a brush to press against the position where the adhesive tape is applied to the twisted pair. After the adhesive tape is cut, a preset upward rotating twisting mechanism holding the twisted pair rotates, and in conjunction with the pressure and friction of the brush, performs a second wrapping action. At this point, the end of the twisted pair is wrapped with adhesive tape. The upward rotating twisting mechanism moves the wrapped twisted pair out of the wrapping station, and the support lifting assembly drives the lifting platform to descend and reset, awaiting the start of the next wrapping process. Based on the above principle, it can be seen that this utility model automatically completes the action of automatically wrapping adhesive tape onto the twisted pair. Compared with the manual wrapping method, this utility model has higher wrapping efficiency and accuracy. At the same time, the layout of each component is reasonable, the overall structure is more compact, and the size is smaller, making it easy to integrate into a twisted pair processing system.

[0029] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0030] This utility model discloses an adhesive tape dot wrapping device, combined with Figures 1 to 9 As shown, it includes:

[0033] The unwinding component 3 is disposed on the translation slide mechanism 20. The unwinding component 3 is used to drive the rolled adhesive tape 30 to slide laterally along the translation slide mechanism 20.

[0034] The cutting and pressing assembly 8 is mounted on the translation slide mechanism 20. The moving end of the cutting and pressing assembly 8 is provided with two vertically aligned cutters 80 and a brush 81 located outside one of the cutters 80. The cutting and pressing assembly 8 is used to drive the two cutters 80 to move relative to each other and cut the adhesive tape 30 between them. At the same time, the brush 81 is used to press against the position of the adhesive tape on the twisted pair 100.

[0035] The top material assembly 5 is provided on the cutting and pressing assembly 8. The lifting and lowering movement end of the top material assembly 5 is provided with a top material block 50. The end of the adhesive tape 30 extends to the top material block 50. The top material assembly 5 is used to drive the top material block 50 to rise so that the end of the adhesive tape 30 is pasted to the bottom of the twisted pair 100 at the spot winding station.

[0036] A bonding component 6 is disposed on the top material block 50. The moving end of the bonding component 6 is provided with a bonding flip block 60. The bonding flip block 60 is hinged to the end of the top material block 50. The bonding component 6 is used to drive the bonding flip block 60 to flip at a preset angle, so as to attach the end of the adhesive tape 30 to the side of the twisted pair cable 100 by means of the bonding flip block 60.

[0037] A pressing assembly 7 is provided on the cutting and pressing assembly 8. The lifting and lowering end of the pressing assembly 7 is provided with a pressing block 70. The pressing block 70 is located above the top material block 50. The pressing assembly 7 is used to drive the pressing block 70 to descend. The clamping of the pressing block 70 and the top material block 50 will press the end of the adhesive tape 30 tightly against the twisted pair cable 100.

[0038] During the operation of the above-mentioned spot-wrapping device, the supporting lifting assembly 1 first drives the lifting platform 10 to rise to a preset height position. Then, the conveying assembly 2 drives the translation slide mechanism 20 to move forward and horizontally, thereby causing the unloading assembly 3, the top-loading assembly 5, the applicating assembly 6, the pressing assembly 7, and the cutting and pressing assembly 8 on the translation slide mechanism 20 to move closer to the spot-wrapping station until the twisted pair 100 is located between the top-loading assembly 5 and the pressing block 70. Then, the adhesive applicating action is performed, with the top-loading assembly 5 driving the top-loading block 50 to rise, through... The top material block 50 attaches the end of the adhesive tape 30 to the bottom of the twisted pair 100 at the spot winding station. Then, side adhesive is applied. The adhesive application assembly 6 drives the adhesive application flipping block 60 to rotate at a preset angle, attaching the end of the adhesive tape 30 to the side of the twisted pair 100. The adhesive tape is then pressed firmly. The pressing assembly 7 drives the pressing block 70 to descend. Based on the clamping of the pressing block 70 and the top material block 50, the end of the adhesive tape 30 is firmly attached to the twisted pair 100. Then, the top material assembly 5 and the pressing assembly 7 retract to their original positions, using the clamping... The upward rotating twisting mechanism of the twisted pair 100 drives the twisted pair 100 to perform a rotational motion. During the rotation of the twisted pair 100, the adhesive tape 30 is wrapped around the twisted node at the end of the twisted pair 100, thus completing the first point-wrapping action. Afterwards, the conveying component 2 drives the translation slide mechanism 20 to move backward, and the adhesive tape 30 on the unwrapping component 3 is unwrapped for the first time. Then, the unwrapping component 3 drives the adhesive tape 30 to move backward along the translation slide mechanism 20 to perform the second unwrapping action. Finally, the cutting and pressing component 8 drives the two cutters 80 to move in opposite directions. The adhesive tape 30 between the two is cut, and the brush 81 presses against the adhesive tape on the twisted pair 100. After the adhesive tape 30 is cut, the preset upward rotating twisting mechanism holding the twisted pair 100 rotates, and the brush 81 presses against the twisted pair 100 to perform a second wrapping action. At this time, the end of the twisted pair 100 has been wrapped with adhesive tape. The upward rotating twisting mechanism moves the twisted pair 100 with the wrapped adhesive tape out of the wrapping station, and the support lifting assembly 1 drives the lifting platform 10 to descend and reset, waiting for the next wrapping process to start. Based on the above principle, it can be seen that this utility model automatically completes the action of automatically wrapping adhesive tape on the twisted pair 100. Compared with the manual wrapping method, this utility model has higher wrapping efficiency and accuracy. At the same time, the layout of each component is reasonable, the overall structure is more compact, and the size is smaller, making it easy to integrate into the twisted pair processing system.

[0039] Please see Figure 5 and Figure 9In this embodiment, the unloading assembly 3 includes an L-shaped slider 31 that slides with the translation slide mechanism 20 and an unloading drive cylinder 32 for driving the L-shaped slider 31 to slide. The vertical end of the L-shaped slider 31 is provided with a tape mounting shaft 33, and the tape 30 is fitted onto the tape mounting shaft 33. The L-shaped slider 31 is used to vertically support the rolled tape 30, and the tape mounting shaft 33 and the tape roll are detachably coupled.

[0040] As a preferred embodiment, during the overall conveying and lifting movements, the material suction function needs to be activated to adsorb a portion of the extended adhesive tape 30 onto the top material block 50. To achieve this function, please refer to [link to relevant documentation]. Figure 6 The top of the top material block 50 is provided with a plurality of straight-line adsorption holes 51. The top material block 50 is provided with a negative pressure channel that communicates with the adsorption holes 51. The outer side of the top material block 50 is provided with a suction kit 4 for generating negative pressure airflow. The suction kit 4 is connected to the negative pressure channel. The adhesive tape 30 is adsorbed onto the top material block 50 by the negative pressure in the adsorption holes 51.

[0041] Furthermore, a throttle valve 40 is provided between the suction end of the suction kit 4 and the negative pressure channel, and the throttle valve 40 is fixed on the top material block 50.

[0042] In order to restrict the adhesive tape 30, in this embodiment, the top of the top material block 50 is provided with an adhesive tape guide groove 52, the adhesive tape 30 is disposed in the adhesive tape guide groove 52, and a plurality of adsorption holes 51 are located at the bottom of the adhesive tape guide groove 52.

[0043] Based on this, the top of the top material block 50 is provided with two guide wheels 53, which are located above the adhesive tape guide groove 52. The guide wheels 53 are used to confine the adhesive tape 30 within the adhesive tape guide groove 52. The guide wheels 53 serve to convey and conduct the adhesive tape 30, and also to confine the adhesive tape 30 within the adhesive tape guide groove 52.

[0044] To achieve lateral adhesive tape application, please refer to the following embodiment: Figure 5The moving end of the material application assembly 6 is provided with a material application top block 61. The material application flipping block 60 includes a flipping block body 600. The flipping block body 600 is hinged to the front end of the top material block 50 near the middle position through a first pin 602. The front end of the flipping block body 600 is provided with a material application stop block 601. The material application stop block 601 is located on the front side of the top material block 50 and there is a gap between the two. The rear end of the flipping block body 600 is hinged to the front end of the material application top block 61 through a second pin 603. In the above structure, when the applicator 6 pushes the flip block body 600 forward through the applicator top block 61, the flip block body 600 flips relative to the top block 50 based on the hinge relationship of the first pin 602, and at the same time the applicator stop 601 flips upward, thereby sticking the end of the adhesive tape 30 to the side of the twisted pair 100. The whole action process is fast and precise, and the applicator 6 has a compact structure and occupies less space.

[0045] In order to ensure good adhesion between the adhesive tape 30 and the twisted pair 100, in this embodiment, the bottom end of the pressing block 70 is formed with pressing teeth 71.

[0047] In a preferred embodiment of this utility model, the conveying component 2, the unloading component 3, the top-loading component 5, the applicating component 6, the pressing component 7, and the cutting and pressing component 8 all use cylinders as driving components.

[0048] Based on this, the present invention also proposes a method for dot-wrapping adhesive tape, which is implemented based on the dot-wrapping device described in the above embodiments, combined with... Figures 1 to 9 As shown, the point-wrapping method includes the following steps:

[0049] Step S1: The supporting lifting assembly 1 drives the lifting platform 10 to rise to a preset height position;

[0050] In step S2, the conveying component 2 drives the translation slide mechanism 20 to move forward and translate, so that the unloading component 3, the top component 5, the pasting component 6, the pressing component 7 and the cutting and pressing component 8 on the translation slide mechanism 20 are close to the point winding station;

[0051] In step S3, the top material assembly 5 drives the top material block 50 to rise, and the top material block 50 is used to stick the end of the adhesive tape 30 to the bottom of the twisted pair 100 at the spot wrapping station.

[0052] In step S4, the adhesive tape assembly 6 drives the adhesive tape flipping block 60 to flip at a preset angle, and the adhesive tape flipping block 60 attaches the end of the adhesive tape 30 to the side of the twisted pair cable 100.

[0053] In step S5, the pressing component 7 drives the pressing block 70 to descend, and the end of the adhesive tape 30 is pressed tightly against the twisted pair cable 100 by the clamping of the pressing block 70 and the top block 50.

[0054] In step S6, the top material assembly 5 and the pressing material assembly 7 retract and reset, and the preset upward rotating twisting mechanism that clamps the twisted pair 100 rotates to wrap the adhesive tape 30 around the twisting node at the end of the twisted pair 100, thus completing the first point wrapping action.

[0055] In step S7, the conveying assembly 2 drives the translation slide mechanism 20 to move backward, and the adhesive tape 30 on the unloading assembly 3 performs the first unloading of the adhesive tape;

[0056] In step S8, the unloading component 3 drives the adhesive tape 30 to retract along the translation slide mechanism 20 to perform the second unloading of the adhesive tape;

[0057] In step S9, the cutting and pressing assembly 8 drives the two cutters 80 to move relative to each other and cuts the adhesive tape 30 between them, while the brush 81 presses against the position of the adhesive tape wrapped on the twisted pair 100.

[0058] Step S10: The preset upward rotating twisting mechanism holding the twisted pair 100 rotates, and the brush 81 presses and rubs to perform a second point winding action.

[0059] Step S11: The upward rotating twisting mechanism drives the twisted pair 100 after the tape is wrapped to move out of the wrapping station;

[0060] In step S12, the supporting lifting assembly 1 drives the lifting platform 10 to descend and reset.

[0061] In the preferred embodiment of this utility model, please refer to Figures 10 to 13The diagram, following the arrow direction, illustrates the sequential actions of the spot-winding device. The process includes: 1) The lifting cylinder of the supporting lifting assembly extends, raising other components to the spot-winding height. 2) The upward rotating twisting mechanism (not shown in the diagram) twists two wires together to form a twisted pair, with the suction function active. 3) The conveying cylinder of the conveying assembly retracts, delivering the unwinding assembly, cutting and pressing assembly, top-loading assembly, applicating assembly, and pressing assembly to the first spot-winding position, with the suction function active. 4) The top-loading cylinder of the top-loading assembly extends, attaching adhesive tape to the bottom of the twisted pair, with the suction function deactivated. 5) The applicating cylinder of the applicating assembly extends, attaching adhesive tape to the side of the twisted pair, with the suction function deactivated. 6) The applicating cylinder of the applicating assembly retracts, and the pressing cylinder of the pressing assembly extends, pressing the twisted pair downwards to ensure a tight fit with the adhesive tape, with the suction function deactivated. Then, the pressure cylinder and the top cylinder retract, and the upward rotating twisting mechanism rotates to wrap the adhesive tape around the twisted node at the end of the twisted pair, completing the first wrapping action. The suction function is off. Next, the conveying cylinder of the conveying component extends and retracts from the first wrapping position to the second wrapping position, simultaneously performing the first tape unwrapping. The suction function is off. Then, the unwrapping cylinder of the unwrapping component extends for the second tape unwrapping, with the suction function off. Next, the cutting cylinder of the cutting and pressing component closes, driving the cutter kit to cut the adhesive tape, while the brush of the pressing kit presses down on the tape. The suction function is off. Then, the upward rotating twisting mechanism rotates for the second wrapping, ensuring the adhesive tape is tightly and neatly wrapped around the twisted pair without misalignment. Simultaneously, the unwrapping cylinder of the unwrapping component retracts, and the suction function is off. The twisted pair with wrapped adhesive tape is then undone. The suction function is activated, the lifting cylinder of the supporting lifting component retracts, lowering and resetting other components. Then, the cutting cylinder of the cutting and pressing component opens. The above process is repeated cyclically to perform the next round of wrapping adhesive tape around both ends of the twisted pair cable. Based on the above principle, it can be seen that this invention automatically completes the process of wrapping adhesive tape around the twisted pair cable. Furthermore, this invention has a compact structure, small size, and high wrapping efficiency and precision.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
