Description

Wire harness coating equipment, integration device and method Technical field

The invention belongs to the field of wire harness production automation equipment, and in particular relates to an automation device used in the field of wire harness production for ultrasonic welding points and pressure riveting adhesive tape insulation wrapping.

Background technique

In the field of wire harness production, it is often necessary to treat the ultrasonic solder joints or riveting parts of the wire harness with tape to insulate and protect. In the previous wire harness production process, the two processes of welding or riveting (only the welding process is mentioned below) and the subsequent bandaging tape were performed independently, that is to say, the two processes were placed in different positions and operated independently. So this kind of arrangement is indispensable for the shortcomings of the transfer of workpieces and the excessive configuration of personnel. At present, many wire harness manufacturers tend to integrate the work content of wrapping tape at the wire harness solder joints into the ultrasonic welding station when optimizing the configuration of the production process. That is, when the operator of the original welding station completes the welding operation of the wire harness, it is necessary to use the connection time as much as possible to complete the tape wrapping work of the wire harness. However, simply transplanting the work content of the bandaging tape to the welding station, and having one operator complete the two parts of the work, is often counterproductive. Not only can it not effectively reduce staff and increase efficiency. On the contrary, due to the complexity of the operation and the breaking of the continuity of the operation, the overall efficiency and output have decreased.

The reason is mainly because the existing automatic tape wrapping equipment takes into account the high-tempo requirements of the equipment itself, and its structural design and working mode are only suitable for independent stations for continuous loading and unloading of operators. When integrated in an ultrasonic welding station, there are two structural problems: the wiring harness clamping position is set farther from the actual rotary encapsulation position; tooling is used to send the wire harness from the clamping position to the rotary encapsulation position. As a result, when combined with the welding station, the upper and lower line clamping positions of the rubber-coated equipment cannot be arranged very close to the welding position of the welding machine. At the same time, when the rubberized cloth machine is running, the wire harness will be pulled a distance to the rotating rubberized position for a second time.

It is conceivable that for the case where the ultrasonic welding machine and the automatic tape wrapping machine are combined in the same station, the wiring harness welding position and the wiring harness clamping and wrapping position are as small as possible, the better it is for the operator to connect up and down the line and work. Because, after the two stations are integrated, the welded wire harness still needs to be manually placed by the operator in the clamping position of the automatic tape machine. The closer the distance, the more convenient the operator's operation.

Based on the urgent need of wire harness manufacturers for an automatic tape covering machine suitable for integrated arrangement with an ultrasonic welding machine, the above-mentioned structural problems existed in the conventional existing automatic tape covering machine. Of course, in addition to the ultrasonic welding machine, the rest of the wire harness connection equipment also has the same technical problems.

Detailed ways

The present invention will be further elaborated and illustrated below in conjunction with the drawings and specific embodiments. The technical features of the various embodiments of the present invention can be combined accordingly without conflict with each other.

The basic structure of the wire harness coating equipment in the present invention includes a displacement drive module, a wire harness coating module, a tape feeding module, and a wire harness clamping module. The function and structure of each part are summarized below.

The wire harness clamping module is responsible for the clamping, positioning, and tensioning of the wire harness in the equipment. Therefore, according to the function, it should be divided into two parts, the clamping positioning mechanism and the tensioning mechanism. Among them, the clamping and positioning mechanism is used for clamping and fixing the wire harness, and the tensioning mechanism is used for clamping and fixing the wire harness. In order to facilitate the connection of the wire harness coating equipment with the previous wire harness processing procedure, the wire harness clamping module should be fixedly arranged on one side of the equipment, and this side can be placed close to the processing equipment of the previous procedure during integration to reduce The movement distance of the person when the operation is switched.

In addition, the role of the tape supply module in the equipment is to provide the tape required for the wire harness encapsulation. According to the functional requirements of the wire harness encapsulation, the tape supply module needs to cut the tape section with a fixed length for subsequent encapsulation. Therefore, according to function, it should be divided into three parts: tape guiding mechanism, tape cutting mechanism and lift control mechanism. Among them, the tape guide mechanism is used to convey the tape to the wire harness coating module to a fixed length; the tape cutting mechanism is used to cut the tape conveyed by the tape guide mechanism to form a tape section; and the lift control mechanism is used to control the tape guide mechanism The tape cutting mechanism moves vertically relative to the wire harness covering module. The vertical movement here can be upward or downward. When moving down, the tape can be accurately transported to the harness covering module below. , And can be close to the temporary fixing mechanism to prevent the tape from deviating from the entrance of the encapsulation mechanism; the first aspect of the upward movement is to tension the tape for cutting, and the second aspect is to adjust the cutting position of the tape to easily control the tape winding The third aspect is that the position of the tape guiding mechanism and tape cutting mechanism can be adjusted to avoid interference during the movement of the wire harness coating module. Since the tape supply module generally does not require personnel to operate except for the process of replacing the tape roll, it can be arranged on the other side of the equipment, keeping a certain distance from the operating station.

Since the tape supply module and the wire harness clamping module are respectively located on both sides of the equipment, and there is a certain spatial distance between the two, the wire harness covering module of the present invention needs to move back and forth between the two. This function is realized by the displacement drive module, and its function is to drive the wire harness covering module to reciprocate between the tape feeding module and the wire harness clamping module.

The function of the wire harness encapsulation module in the equipment is to stick the tape segment cut to the fixed length to the surface of the wire harness, and provide continuous rotation motion to tightly wrap the tape on the corresponding surface of the wire harness. Moreover, in this device, the wire harness covering module needs to carry the cut tape segment to move to the harness clamping module, so it should also be able to temporarily fix the cut tape segment. Therefore, according to the function, it should be divided into two parts: the temporary fixing mechanism of the tape and the covering mechanism. Among them, the tape temporary fixing mechanism is used to temporarily fix the tape section cut by the tape cutting mechanism so that it is suspended outside the wire harness entrance of the encapsulating mechanism, and the encapsulating mechanism is used to use the tape section to clamp the positioning mechanism. The wire harness is wound and encapsulated.

Based on the wire harness wrapping equipment, the wire harness wrapping can be realized according to the following control methods:

S1: Control the wire harness covering module to be in the initial position close to the adhesive cloth feeding module through the displacement drive module, and the adhesive cloth of the adhesive cloth feeding module can just be output to the outside of the wire harness inlet of the covering mechanism in the wire harness covering module;

S2: Control the work of the tape guide mechanism in the tape feeding module, deliver the tape to the outside of the wire harness entrance of the lower encapsulation mechanism according to the encapsulation requirements, and then control the tape temporary fixing mechanism to temporarily fix the tape, and then pass The lifting control mechanism makes the tape guide mechanism to drive the tape up. During the tape up process, it needs to overcome the fixing force exerted by the tape temporary fixing mechanism on the tape, so that the tape is stretched while the head length of the tape meets the set requirements. Finally, the tape is cut by the tape cutting mechanism, and a tape section suspended and fixed by the tape temporary fixing mechanism is formed outside the wire harness entrance of the encapsulation mechanism, and the adhesive surface of the tape section is kept facing the direction of the harness clamping module to complete the tape preparation;

S3: After the wire harness is clamped and fixed by the clamping positioning mechanism in the wire harness clamping module, control the tensioning mechanism to tension the wire harness;

S4: After the wire harness is clamped and tensioned, the displacement drive module is used to control the movement of the wire harness coating module to the wire harness clamping module. During the movement, the position of the wire harness to be coated contacts the adhesive surface of the tape, and then continues to drive the tape When leaving the temporary fixing mechanism of the tape and entering the turning center of the encapsulating wheel in the encapsulating mechanism, the wire harness encapsulating module stops moving;

S5: The controlled encapsulation mechanism winds and encapsulates the position of the wire harness to be encapsulated, and after the encapsulation is completed, the displacement drive module controls the wire harness encapsulation module to return to the initial position.

The above is the basic functional realization form of the wire harness coating equipment, and each mechanism in it can adopt any component that can realize the corresponding function. The following will describe some preferred realization forms of each module.

As shown in Figure 1, it is a preferred layout form of the wire harness covering equipment, in which the wire harness clamping module 5 is fixedly arranged at the front end of the equipment base plate 1, and the rear end of the wire harness covering module 3 is arranged. The glue module 3 is arranged on the linear guide rail 2, and the linear guide rail 2 is arranged longitudinally on the equipment bottom plate 1 so that the wire harness coating module 3 can move closer to and away from the wire harness clamping module 5 along the linear guide 2. The linear guide 2 has its own drive power structure. A tape supply module 4 is arranged on one side of the wire harness coating module 3, and the tape supply module 4 is relatively far away from the wire harness clamping module 5 on the base plate 1.

As shown in Figure 2, the wire harness coating module 3 is composed of: a module base 301, a rubber coating wheel 302, a rubber coating spring 303, a tape holding rod slide 304, a tape holding rod 305, a tape pre-pressing roller 307, and a tape pre-pressing roller. The roller support plate 308, the transmission gear set 309, and the drive motor 310 are composed. The module base 301 is the base part of the module, on which various functional parts are arranged; the front part of the module base 301 is provided with a rubber-coated wheel 302, which can rotate around the support. The rubber-coated wheel is an annular revolving member with an opening. Two rubber-coated elastic pieces 303 are arranged on the rubber-coated wheel 302, and the rubber-coated elastic pieces are pressed against each other by the spring members. The rubber-coated wheel 302 and the rubber-coated elastic piece 303 form a functional part for rotating rubber-coating. The rubber-coated wheel 302 is provided with gears for power transmission of rotational movement; a driving motor 310 is provided behind the module base 301, and the driving motor drives the rubber-coated wheel 302 to rotate through the transmission gear set 309 provided. Of course, in addition to the form of the rotation driving device of the rubber-coated wheel 302, it is not limited to this, any form that can drive it to rotate around the center of rotation is acceptable. The base 301 of the rubber-coated module is provided with a channel for the wire harness to enter the center of rotation of the rubber-coated wheel 302. Two upper and lower tape pre-pressing rollers 307 are arranged in front of the channel entrance of the rubber-coated module base 301, and the two sides of the tape pre-pressing roller are respectively connected to the module base 301 through tape pre-pressing roller support plates. The tape pre-pressing roller can rotate freely relative to the connection point of the pre-pressing roller support plate. The pre-pressing roller support plates on both sides and the tape pre-pressing roller form a swing arm structure, which can swing freely around the connection point at the module base 301 as a fulcrum. At the same time, the upper and lower swing arm structures are connected by a spring structure, so that the upper and lower tape pre-pressing rollers 307 are pressed against each other. When the wire harness with the tape passes through the upper and lower tape pre-pressing rollers 307, the upper and lower tape pre-pressing rollers 307 will apply opposing pressure to them, so that the tape is pre-adhered to the harness before entering the center of rotation. When it continues to enter the center of rotation, it can be further bonded under the pressing force of the upper and lower rubber-coated elastic pieces 303, and as the rubber-coated wheel 302 rotates, the remaining tape can be gradually wound on the wire harness. The module base 301 is located above the tape pre-pressing roller 307 and is flush with the outer periphery of the pre-pressing roller, and is provided with a vertical plane, that is, the tape supporting surface 306. A cylindrical tape holding rod 305 is arranged in the vertical direction on the tape supporting surface, and the tape holding rod is installed on the holding rod sliding seat 304. The holding rod sliding seat can move along a direction perpendicular to the tape support surface 306, so that the tape holding rod 305 can be attached to the compressed tape support surface 306, or can be away from the release tape support surface. The tape holding rod may be able to rotate freely around an axis and the axial direction is parallel to the tape supporting surface 306. In order to reduce the adhesion with the tape, the surface of the tape holding rod 305 may be knurled. When the tape is pressed on the tape support surface 306 by the tape holding rod 305, the lower part of the tape should hang freely outside the wire harness inlet of the encapsulation mechanism, so that the tape can be brought along when the wire harness enters the wire harness inlet of the encapsulation mechanism enter. In the wire harness covering module 3 shown in FIG. 2, the wire harness inlet of the covering mechanism refers to the inlet formed by two tape pre-pressing rollers 307. In order to ensure that the wire harness can smoothly bring the tape into the encapsulation mechanism, the wire harness entrance to the encapsulation mechanism should not be too large when the tape drapes freely. Therefore, the tape support surface 306 is best to be flush with the outer end surface of the encapsulation mechanism's wire harness entrance or slightly Keep a little distance. In the wire harness covering module 3, the outer end surface of the wire harness inlet of the covering mechanism is the leftmost outer end surface of the two tape pre-pressing rollers 307.

Of course, in the three types of wire harness encapsulation modules, the two swing arm structures can be directly used in other forms that can achieve elastic compression, in addition to applying pressure through springs, such as directly using elastic materials to make a tape pre-compression roller support 308. Similarly, the rubber-coated elastic piece 303 inside the rubber-coated wheel 302 can also be made of elastic material to omit the spring.

In addition, although the above-mentioned tape support surface 306 is a plane perpendicular to the horizontal direction, changing it to a slight angle with the horizontal does not affect the realization of its function in theory. However, if the angle is too large, when the tape is pressed on the tape support surface 306, the position of the tape will be bent, and it is not easy to control its hanging posture outside the wire harness inlet of the encapsulation mechanism.

In addition, the tape holding rod sliding seat 304, tape holding rod 305, and tape support surface 306 actually constitute the aforementioned tape temporary fixing mechanism, which can temporarily fix the tape segment cut by the tape cutting mechanism so that it can be suspended. Outside the wire harness entrance of the encapsulation mechanism. Of course, the implementation form of the tape temporary fixing mechanism is not limited to this. In other embodiments, the tape holding rod 305 may also be in the form of a tape pressing piece other than a round rod, such as a thin flat plate, a grid plate, and a wave point plate. Etc., such a plate body can press the tape on the tape support surface 306 with a small contact area, and can also play a role of temporary fixation. However, due to the pressure applied in the form of a plate, the plate itself cannot be rotated, so when the tape moves upward, it will have a certain impact on its sticky surface.

In addition, the tape holding rod sliding seat 304 can also be changed to other adjustment components that drive the tape holding rod 305, for example, other sliding parts can be used instead, as long as the sliding part and the rubberized module base 301 constitute an adjusting tape pressing part and a tape A sliding pair with a spacing between the supporting surfaces 306 is sufficient.

In another embodiment, the temporary fixing mechanism for the tape can also be realized by a negative pressure suction structure, that is, a negative pressure suction port is opened on the tape support surface 306, and a negative pressure suction device is connected. When the tape passes through the negative pressure When the suction port is sucked, the tape can be sucked on the tape support surface 306 through negative pressure suction. The size of the adhesion force can be controlled by adjusting the negative pressure, and the fixing and release of the tape can be conveniently controlled.

As shown in Figure 3, the tape supply module 4 is composed of: tape supply module base 401, linear motion module 402, film spool 403, tape roll 404, tape guide roller 405, tape conveying wheel assembly 406, scissors 407 408 composed of untied tape. The base 401 of the adhesive tape feeding module is the base part of the module, on which various functional parts are arranged; the base 401 of the adhesive plaster feeding module is connected with the slider of the linear motion module 402. The linear motion module 402 is arranged in the vertical direction, and the slider can move in the vertical direction; a film spool 403 is arranged above the module base 401, and a film roll 404 used for work can be mounted on the film spool 403. The unwound adhesive cloth 408 passes the adhesive cloth guide roller 405 in the direction shown in the figure, and after passing the two rollers of the adhesive cloth conveying wheel assembly 406, extends downward and passes through the cutting position of the scissors 407. As shown in FIG. As shown in Figure 3, the installation method of the unwound tape 408 and tape roll is that the non-adhesive surface of the tape is in contact with the surface of the tape guide roller 405, and the adhesive surface 409 of the tape is in contact with the surfaces of the two rollers of the tape conveying wheel assembly 406. . The surfaces of the two rollers of the tape conveying wheel assembly 406 are knurled to reduce the adhesion between the tape and the tape. Moreover, the two rollers are arranged staggered up and down, rotating at a differential speed. The speed of the upper roller is lower than that of the lower roller. After the tape is unwound from the tape roll 404 by the rotation of the upper roller, it continues to be transported to the side of the lower roller. The rotation speed of the roller is faster, so that the adhesive surface 409 of the tape can be released from the surface of the upper roller in time, and then be transported vertically downward under the action of gravity. Since the length of the tape is fixed during the wire harness coating process, the tape conveying wheel assembly 406 should transfer the untwisted tape at a fixed length after pulling (untwisting) the tape roll. This can be achieved by servo-controlling the rotation angle of the roller. . When the tape is transported to a specific position, the tape can be cut by controlling the scissors 407 to form an independent tape section.

Similarly, the tape supply module 4 is only one of the implementation forms. In other embodiments, the linear motion module 402 can use any device that can achieve vertical vertical lifting, but its control accuracy should meet the requirements. . In addition, the scissors 407 can also be replaced by other tape cutting mechanisms, such as laser cutting equipment. In some special cases, the tape can also be replaced by other tape sources other than the tape roll 404, and there is no need to set the film roll 403 in this case. In addition, in addition to the above-mentioned double roller design, the adhesive tape conveying wheel assembly 406 may also adopt other existing adhesive tape conveying equipment, as long as the adhesive tape can be conveyed at a fixed length.

As shown in FIG. 4, the wire harness clamping module 5 is composed of a clamping module base 501, a wire clamping support 502, a synchronization gear 503, a wire clamping assembly 504, a flexible polyurethane block 505, and a wire harness tensioning cylinder 506. In order to make the wire harness clamping position as close as possible to the front of the device, the wire harness clamping module is set in the frame structure shown in the figure, allowing the rear covering module 3 to pass through from the middle to the wire harness clamping position for covering. The clamping module base 501 is the base part of the module, on which various functional parts are arranged, and the middle part has a channel space for the rubber encapsulation module 3 to extend into. The wire clamping components 504 are arranged at the front end of the module and are distributed on both sides of the clamping module base 501. The wire clamping assembly 504 is a positioning and clamping part of the wire harness, and can be in the form of clamping jaws, wire clamping arms, and the like. Since the wire clamping component 504 is generally made of metal material, it is easy to cause loss to the wire harness when the clamping force is too large. Therefore, the clamping part of the wire clamping component that contacts the wire harness is preferably inlaid with a flexible polyurethane block 505 for the purpose of clamping When holding the surface of the wire harness, only allow the flexible polyurethane surface to contact the surface of the wire harness to be stressed to prevent the wire skin from being pinched. Of course, the flexible polyurethane block can also be replaced with other flexible protective parts. If there are other ways to prevent damage to the wiring harness, the flexible protective parts may not be provided. The thread clamping components 504 on the left and right sides are respectively installed on the thread clamping supports 502 on the left and right sides. A certain distance should be maintained between the two, and in order to ensure that the wire harness is kept in a tensioned state when encapsulating, it should be provided by a tensioning mechanism. The horizontal distance between the clamping positions of the wire harnesses on the two wire clamping assemblies 504 is controlled.

In this equipment, the tensioning mechanism is a synchronous tensioning mechanism, which can control the left and right clamping supports 502 to drive the two clamping assemblies 504 to move at an equal rate to both sides in the direction of the arrow shown in FIG. 5. The synchronous tensioning mechanism is composed of a clamping module base 501, a wire clamping support 502, a synchronous gear 503 and a wire harness tensioning cylinder 506. The horizontal end of the wire clamping support 502 on the left and right sides are respectively provided with structural parameters With the same straight rack structure, the horizontal part of the clamping support 502 and the top of the clamping module base 501 constitute a sliding pair. Two straight rack structures are arranged on both sides of the synchronous gear 503 at intervals, and mesh with the synchronous gear 503 respectively. One of the wire clamping supports 502 is fixed with a wire harness tensioning cylinder 506, and the output shaft of the wire harness tensioning cylinder 506 is supported on the clamping module base 501. When the output shaft of the wire harness tensioning cylinder 506 is ejected, it can be Push the wire clamping support 502 where it is located away from the clamping module base 501, and under the synchronous transmission of the synchronization gear 503, the two clamping supports 502 can extend the distance in opposite directions at the same sliding rate, and then The wire harnesses clamped on the two wire clamping assemblies 504 are driven to be simultaneously tensioned to both sides. Of course, in addition to the foregoing implementation form, the gear power mechanism for driving the synchronous gear 503 can also be implemented by a motor or the like in addition to an air cylinder. The synchronous driving device for driving the two wire clamping supports 502 can also be realized by a similar linkage mechanism, or it can be realized in the form of two air cylinders separately and synchronously driving the wire clamping supports 502 on both sides, as long as the wire harness can be tensioned. . The tensioning mechanism can also be tensioned asynchronously on both sides, but it is preferably tensioned synchronously.

Based on the above-mentioned Figures 1 to 5, a preferred implementation form of the wire harness coating equipment of the present invention is shown. Since the device arranges the clamping position of the wire harness at the foremost position of the equipment as much as possible, it is easy to integrate into the ultrasonic welder. Place as close as possible to the ultrasonic welding machine. In addition, the encapsulation operation process adopts the wire harness to be clamped and the encapsulation module is moved to the wire harness clamping position to avoid the secondary pulling problem caused by the movement of the wire harness. In addition, the tape feeding method adopts a separate design, which maintains independent operation from the working cycle, and does not operate in conjunction with other beat actions, which improves the stability and reliability of tape feeding.

FIG. 6 is a schematic diagram of the arrangement of the above-mentioned wire harness covering tape equipment of the present invention after being combined with the ultrasonic welding machine 6. As can be seen from the figure, in the wire harness coating equipment, the wire harness clamping module 5 is arranged at the end close to the ultrasonic welding machine 6, and the adhesive cloth feeding module 4 is arranged at the end far away from the ultrasonic welding machine 6. Therefore, the wire harness clamping position of the wire harness tape equipment can be arranged close to the offline beam welding position, and the distance A required to move between the welded wire harness 7 and the clamped wire harness 8 becomes very small. The configuration of the above structure improves the feasibility of integrating the tape-covering machine into the ultrasonic welding station, and satisfies that the operator can operate two devices at the same time by one person, and complete the wire harness welding and tape-covering work in the same station in sequence. Due to the reasonable design of the equipment structure, it has little effect on the working cycle of the original ultrasonic welding, and the original waiting time during welding can be used to complete the bandaging work of the welded wiring harness, which can play a role in one person and two machines, reducing the on-site personnel of the wiring harness manufacturer. Configuration, reduce intermediate logistics and transfer links, truly reduce staff and increase efficiency, reduce production costs, and improve production efficiency. Moreover, the arrangement of the equipment is also very flexible, without the need for additional transformation workbenches, and the old workbenches of the wiring harness manufacturers can be used as much as possible.

FIG. 7 shows that when the above-mentioned wire harness covering cloth equipment of the present invention is working, when the covering module 3 moves forward to the covering position, the wire harness remains stationary, and there is no problem of secondary movement (pulling).

The workflow of the integrated device shown in Figure 6 is described as follows:

The equipment workflow is divided into the following four steps:

1. Adhesive fabric preparation: As shown in Figure 8, the rubber covering module 3 is in the waiting position, and the linear motion module 402 of the adhesive fabric feeding module 4 drives the feeding module to move down to a suitable position, keeping the rod sliding seat 304 forward Move to make the tape holding rod 305 away from the tape holding surface 306 by a certain distance (so that the tape can pass through smoothly, theoretically, the larger the distance, the better). Then the tape conveying wheel group 406 starts to rotate, as shown in FIG. 9, while the tape is unwound, the unwound tape passes through the space between the tape holding rod 305 and the tape holding surface 306, and is transported to the tape of the encapsulation module 3 Pre-press the position in front of the roller, and control the length of the tape output (discharge) according to the set value. In the state shown in FIG. 10, after the adhesive tape is discharged to the set length, the holding rod sliding seat 304 moves backward, so that the adhesive holding rod 305 presses the adhesive tape on the adhesive holding surface 306. Then, the linear motion module 402 drives the feeding module to move upward, and drives the tape head to be adjusted to a proper position, as shown in FIG. 10. As shown in FIG. 11, the scissors are activated to cut the tape. After the tape is cut, the linear motion module 402 drives the feeding module to move upward to the initial state. All relevant parts are restored to their original positions, and the tape preparation is completed.

2. Manual on-line: The operator welds the wire harness in the ultrasonic welding machine 6, and then manually sends the welded wire harness to the wire harness clamping position, and triggers the start switch of the wire harness tape equipment, and the wire harness clamping module 5 sets the wire harness Automatic clamping, and automatic tensioning to both sides, so that the wire harness maintains an ideal posture. As shown in Figure 6.

3. Automatic encapsulation: After the wire harness is clamped and tensioned, the encapsulation module 3 moves forward to the encapsulation position, as shown in Figure 7. In the initial stage when the rubber covering module moves forward, the holding rod sliding seat 304 also slightly moves forward by a distance B, as shown in FIG. Stick to the surface of the tape holding rod 305; as the encapsulation module 3 moves further forward, the tensioned wire harness at the clamping position first comes into contact with the adhesive surface of the tape, as shown in Figure 12, on the upper and lower tape pre-pressing rollers Under compression, the tape is pre-coated on the surface of the wire harness; entering the state shown in Figure 13, the rubber encapsulation module 3 stays on the wire harness just at the center of rotation of the rubber wheel 302, and passes through the pressure of the front tape pre-pressing roller. For cooperation, the first loop of tape has been pre-wrapped to the surface of the wire harness; then the motor is started to drive the rubber wheel 302 to continuously rotate. The shape of the bandaging tape 10 is shown in Figure 14. After the automatic gluing process is completed, the gluing module 3 returns to the initial position, and the tape conveying module goes down again to enter the tape preparation cycle.

4. Manual off-line: The operator removes the wrapped wire harness manually, and exchanges a new uncoated wire harness.

Of course, the device of the present invention is not only specifically developed for the above-mentioned integration with the ultrasonic welding machine station, but the unique structure and working mode of the device is very suitable for the working mode integrated with the ultrasonic welding machine. In addition to the ultrasonic welding machine, other wire harness bonding equipment used to electrically connect the wires in the wire harness that need to be bonded can also be integrated with the wire harness coating equipment of the present invention, such as other wire harness welding equipment or wire harness riveting equipment.

Of course, as a kind of automatic tape wrapping equipment, the present invention has the basic functions of traditional similar equipment, and can also be used alone for conventional independent wire harness wrapping stations.

It can be seen that the present invention also has the basic functions of conventional encapsulation equipment, and takes into account the independent use of independent encapsulation stations. When the wire harness coating equipment of the present invention is integrated and applied to the ultrasonic welding station, due to the reasonable structure design of the equipment, the operator can take into account the operation of the two equipment at the same time, and has little effect on the working rhythm of the original ultrasonic welding. One person and two machines can improve production efficiency.

The above-mentioned embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. Those of ordinary skill in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all technical solutions obtained by equivalent substitutions or equivalent transformations fall within the protection scope of the present invention.
