Description

Technical Field

[0001] The invention belongs to the field of wire harness production automation equipment, and specifically relates to an automation equipment for ultrasonic welding points, riveting points, and adhesive tape insulation wrapping in the wire harness production field. Background Art

[0002] In the field of wire harness production, it is often necessary to wrap the ultrasonic welding points or riveting points of the wire harness with tape to play the role of insulation and protection. In the past, in the process of wire harness production, welding or riveting (hereinafter only the welding process is mentioned) and the subsequent wrapping tape were carried out independently, that is, the two processes were placed in different positions and operated independently. Then this arrangement is inevitable for the transfer of workpieces and excessive configuration of personnel. At present, many wire harness manufacturers tend to integrate the work content of wrapping tape at the welding points of the wire harness 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, he must use the connection time as much as possible to complete the work of wrapping tape for the wire harness. Simply transplanting the work content of wrapping 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 brought to the operator and the disruption of the continuity of the operation, the overall efficiency and output have decreased.

[0003] The main reason is that the existing automatic tape laminating equipment takes into account the high cycle requirements of the equipment itself, and its structural design and working mode are only suitable for independent workstations for operators to continuously load and unload materials. When integrated into the ultrasonic welding station, there are two structural problems: the harness clamping position is far away from the actual rotating tape laminating position; and the harness is sent from the clamping position to the rotating tape laminating position using tooling. As a result, when combined with the welding station, the upper and lower wire clamping positions of the tape laminating equipment cannot be arranged very close to the welding position of the welding machine. At the same time, when the tape laminating machine is running, it will also pull the harness a distance to the rotating tape laminating position for a second time.

[0004] It is conceivable that when the ultrasonic welding machine and the automatic tape wrapping machine are combined in the same station, the smaller the distance between the wire harness welding position and the wire harness clamping and tape wrapping position is, the more convenient it is for the operator to connect 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 wrapping machine. The closer the distance is, the more convenient it is for the operator to operate.

[0005] The wiring harness manufacturers are in urgent need of an automatic tape covering machine that can be integrated with an ultrasonic welding machine, and the conventional existing automatic tape covering machines have the above structural problems. Of course, in addition to ultrasonic welding machines, the rest of the wiring harness connection equipment also has the same technical problems. Summary of the invention

[0006] The purpose of the present invention is to solve the defect that when a conventional tape wrapping machine is integrated into a wire harness connection equipment station, the distance between the wire harness welding position and the tape wrapping position is too large, resulting in inconvenient operation; at the same time, it is also to solve the problem of secondary pulling of the wire harness caused by the movement of the wire harness to the tape wrapping position when the automatic tape wrapping machine is running, and to provide a wire harness tape wrapping device.

[0030] Another object of the present invention is to provide a method for controlling wire harness rubber coating using the wire harness rubber coating equipment as described in any of the above schemes, the steps of which are as follows:

[0031] S1: Controlling the wiring harness rubber coating module to be in an initial position close to the adhesive tape feeding module by the displacement driving module, so that the adhesive tape of the adhesive tape feeding module can just be output to the outside of the wiring harness inlet of the adhesive coating mechanism in the wiring harness rubber coating module;

[0032] S2: Control the tape guiding mechanism in the tape feeding module to work, and convey the tape of a fixed length to the outside of the harness entrance of the rubber coating mechanism below, and then control the tape temporary fixing mechanism to temporarily fix the tape, and then drive the tape to rise by the tape guiding mechanism through the lifting control mechanism, and make the tape head length meet the set requirements while tensioning the tape; finally, cut the tape through the tape cutting mechanism, and form a tape segment suspended and fixed by the tape temporary fixing mechanism outside the harness entrance of the rubber coating mechanism, and keep the sticky surface of the tape segment facing the harness clamping module, and complete the tape preparation;

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] In the device of the present invention, the wire harness is fixed in the clamping position, avoiding the problem of secondary pulling of the wire harness. When the device is combined with an ultrasonic welding machine, since the wire harness clamping position is arranged close enough to the welding position, it is convenient for the operator to get on and off the line, reducing the mutual pulling between the wire harnesses. At the same time, the tape feeding method adopts a separate design, which maintains independent operation in terms of working rhythm, and does not cooperate with other rhythm actions to operate, thereby improving the stability and reliability of tape feeding. When the device is applied to the integrated work of the ultrasonic welding station, the operator can operate two devices at the same time, and complete the welding and tape wrapping of the wire harness in the same station in sequence. Due to the reasonable design of the equipment structure, it has little effect on the original ultrasonic welding working rhythm, and can also use the original waiting time during welding to complete the tape wrapping work of the welded wire harness. Of course, in addition to the ultrasonic welding machine, the present invention can also solve similar problems existing in other wire harness joint connection equipment. The present invention achieves the effect of one person using two machines, reducing the on-site personnel configuration of the wiring harness manufacturer, reducing the intermediate logistics and transportation links, and truly achieving the goal of reducing staff and increasing efficiency, reducing production costs, and improving production benefits.

DETAILED DESCRIPTION

[0053] The present invention is further described and illustrated below in conjunction with the accompanying drawings and specific embodiments. The technical features of each embodiment of the present invention can be combined accordingly without conflicting with each other.

[0054] The basic structure of the wire harness tape wrapping device of the present invention includes a displacement drive module, a wire harness tape wrapping module, a tape feeding module and a wire harness clamping module. The functions and structures of each part are summarized below.

[0055] The harness clamping module is responsible for clamping, positioning, and tensioning the harness in the equipment. Therefore, it should be divided into two parts according to its functions: a clamping and positioning mechanism and a tensioning mechanism. The clamping and positioning mechanism is used to clamp and fix the harness, while the tensioning mechanism is used to tension the clamped and fixed harness. In order to facilitate the connection between the harness tape wrapping equipment and the previous harness processing procedure, the harness clamping module should be fixed on one side of the equipment. During integration, this side can be placed close to the processing equipment of the previous process to reduce the distance that personnel need to move when switching operations.

[0056] In addition, the function of the tape feeding 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 feeding module needs to cut the tape segments of a certain length for subsequent encapsulation. Therefore, according to the function, it should be divided into three parts: the tape guiding mechanism, the tape cutting mechanism and the lifting control mechanism. Among them, the tape guide mechanism is used to convey the tape to the wire harness rubber wrapping module at a fixed length; the tape cutting mechanism is used to cut the tape conveyed by the tape guide mechanism to form a tape segment; and the lifting control mechanism is used to control the vertical relative movement of the tape guide mechanism and the tape cutting mechanism relative to the wire harness rubber wrapping module. The vertical movement here can be upward or downward. When moving downward, the tape can be accurately conveyed to the wire harness rubber wrapping module below, and can be close to the temporary fixing mechanism to prevent the tape from deviating from the entrance of the rubber wrapping mechanism; and the purpose of the upward movement is firstly to tension the tape for easy cutting, secondly to adjust the cutting position of the tape, and conveniently control the length of the tape when winding, and thirdly to adjust the position of the tape guide mechanism and the tape cutting mechanism to avoid interference during the movement of the wire harness rubber wrapping module. Since the tape feeding module generally does not require personnel to operate except for processes such as replacing the tape roll, it can be arranged on the other side of the equipment and kept a certain distance from the operating station.

[0057] Since the adhesive tape feeding module and the harness clamping module are located on both sides of the device, and there is a certain space distance between the two, the harness rubber coating module of the present invention needs to move back and forth between the two. This function is achieved by a displacement driving module, which drives the harness rubber coating module to move back and forth between the adhesive tape feeding module and the harness clamping module.

[0058] The function of the wire harness rubber wrapping module in this equipment is to stick the tape segments cut to a fixed length to the surface of the wire harness, and provide continuous rotational motion to tightly wrap the tape to the corresponding surface of the wire harness. And because in this device, the wire harness rubber wrapping module needs to carry the cut tape segments to move to the wire harness clamping module, it should also be able to temporarily fix the cut tape segments. Therefore, according to the function, it should be divided into two parts: a temporary tape fixing mechanism and a rubber wrapping mechanism. Among them, the temporary tape fixing mechanism is used to temporarily fix the tape segments cut by the tape cutting mechanism so that they are suspended outside the wire harness entrance of the rubber wrapping mechanism, while the rubber wrapping mechanism is used to use the tape segments to wrap the wire harness on the clamping and positioning mechanism.

[0059] Based on the wire harness tape equipment, the wire harness tape can be realized according to the following control method:

[0060] S1: Control the wiring harness glue coating module to be in an initial position close to the adhesive tape feeding module in advance through the displacement driving module, so that the adhesive tape of the adhesive tape feeding module can just be output to the outside of the wiring harness inlet of the glue coating mechanism in the wiring harness glue coating module;

[0061] S2: Control the tape guiding mechanism in the tape feeding module to work, and convey the tape to the outside of the harness entrance of the lower glue wrapping mechanism at a fixed length according to the glue wrapping requirements, and then control the tape temporary fixing mechanism to temporarily fix the tape, and then use the lifting control mechanism to drive the tape guiding mechanism to rise. During the tape rising process, it is necessary to overcome the fixing force applied by the tape temporary fixing mechanism to the tape, thereby tensioning the tape through the rising of the tape while making the remaining length of the tape meet the set requirements; finally, the tape is cut by the tape cutting mechanism, and a tape segment suspended and fixed by the tape temporary fixing mechanism is formed outside the harness entrance of the glue wrapping mechanism, and the sticky surface of the tape segment is kept facing the direction of the harness clamping module, and the tape preparation is completed;

[0062] S3: After the wire harness is clamped and fixed by the clamping and positioning mechanism in the wire harness clamping module, the tensioning mechanism is controlled to tension the wire harness;

[0063] S4: After the wire harness is clamped and tensioned, the wire harness glue coating module is controlled by the displacement driving module to move toward the wire harness clamping module. During the movement, the position of the wire harness to be glued contacts the sticky surface of the tape, and then the tape is driven to separate from the temporary fixing mechanism of the tape and enter the rotation center of the glue coating wheel in the glue coating mechanism. The wire harness glue coating module stops moving;

[0064] S5: The controlled glue coating mechanism wraps and coats the position of the wire harness to be coated with glue. After the coating is completed, the displacement driving module controls the wire harness coating module to return to the initial position.

[0065] The above is the basic functional implementation form of the wire harness tape wrapping equipment, and each mechanism therein can adopt any component that can realize the corresponding function. The following will describe some preferred implementation forms of each module.

[0066] like Figure 1 As shown, it is a preferred layout form of the wire harness tape wrapping equipment, wherein the wire harness clamping module 5 is fixedly arranged at the front end of the equipment base plate 1, and the wire harness tape wrapping module 3 is arranged at the rear end thereof, and the wire harness tape wrapping module 3 is arranged on the linear guide rail 2, and the linear guide rail 2 is longitudinally arranged on the equipment base plate 1, so that the wire harness tape wrapping module 3 can move relatively close to and away from the wire harness clamping module 5 along the linear guide rail 2. The linear guide rail 2 has its own driving power structure. A tape feeding module 4 is arranged on one side of the wire harness tape wrapping module 3, and the tape feeding module 4 is relatively far away from the wire harness clamping module 5 on the base plate 1.

[0067] like Figure 2As shown, the wiring harness rubber 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, a tape pre-pressing roller support plate 308, a transmission gear set 309, and a driving motor 310. 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 arranged with a rubber coating wheel 302, and the rubber coating wheel can rotate around the support. The rubber coating wheel is an annular rotating part with an opening, and the rubber coating wheel 302 is arranged with two upper and lower rubber coating springs 303, and the rubber coating springs are pressed against each other by spring parts. The rubber coating wheel 302 and the rubber coating spring 303 constitute a functional part for rotating rubber coating. The rubber-coated wheel 302 is provided with a gear part for power transmission of rotational motion; a driving motor 310 is provided at the rear of the module base 301, and the driving motor drives the rubber-coated wheel 302 to rotate through the transmission gear set 309. Of course, the rotation drive device of the rubber-coated wheel 302 is in various forms, but not limited to this, and any form that can drive it to rotate around the center of rotation is acceptable. The rubber-coated module base 301 is provided with a channel for the wiring harness to enter the center of rotation of the rubber-coated wheel 302. An upper and lower rubber tape pre-pressing roller 307 are arranged in front of the channel entrance of the rubber-coated module base 301, and the two sides of the rubber tape pre-pressing roller are respectively connected to the module base 301 through the rubber 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 together form a swing arm structure, which can swing freely around the connection point located 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 passes through the upper and lower tape pre-pressing rollers 307 with the tape, the upper and lower tape pre-pressing rollers 307 will apply opposite pressure to it, so that the tape is pre-pasted on the wire harness before entering the center of rotation. After it continues to enter the center of rotation, it can be further fitted under the pressing force of the upper and lower rubber-coated springs 303, and as the rubber-coated wheel 302 rotates, the remaining tape can be gradually wound around the wire harness. A vertical plane, namely the tape support surface 306, is provided on the module base 301 above the tape pre-pressing roller 307 and flush with the outer periphery of the pre-pressing roller. A cylindrical tape holding rod 305 is arranged in the vertical direction of the tape support surface, and the tape holding rod is installed on the holding rod slide 304. The holding rod slide can move in a direction perpendicular to the tape support surface 306, so that the tape holding rod 305 can fit and press the tape support surface 306, or can move away from the tape support surface. The tape holding rod can rotate freely around the axis and the axial direction is parallel to the tape support surface 306. In order to reduce the stickiness between the tape and the tape, the surface of the tape holding rod 305 can be knurled.When the tape is pressed onto the tape support surface 306 by the tape holding rod 305, the lower part of the tape should be freely suspended outside the harness entrance of the rubber coating mechanism, so that the tape can be brought in together with the harness when the harness enters the harness entrance of the rubber coating mechanism. Figure 2 In the wiring harness rubber coating module 3 shown, the wiring harness entrance of the rubber coating mechanism refers to the entrance formed by two adhesive tape pre-pressing rollers 307. In order to ensure that the wiring harness can smoothly bring the adhesive tape into the rubber coating mechanism, the distance between the adhesive tape and the wiring harness entrance of the rubber coating mechanism in the freely suspended state should not be too large, so the adhesive tape support surface 306 is preferably flush with the outer end surface of the wiring harness entrance of the rubber coating mechanism or maintain a slight distance. In the wiring harness rubber coating module 3, the outer end surface of the wiring harness entrance of the rubber coating mechanism is the leftmost outer end surface of the two adhesive tape pre-pressing rollers 307.

[0068] Of course, in the wire harness rubber coating module 3, in addition to applying pressure through springs, the two swing arm structures can also directly adopt other forms that can achieve elastic compression, such as directly making the rubber pre-pressing roller support plate 308 with elastic material. Similarly, the rubber coating spring piece 303 inside the rubber coating wheel 302 can also be made of elastic material to omit the spring member.

[0069] In addition, although the above-mentioned adhesive tape support surface 306 is a plane perpendicular to the horizontal direction, it is theoretically not affected to change it to a slightly angled one from the horizontal direction. However, if the angle is too large, when the adhesive tape is pressed on the adhesive tape support surface 306, it will bend at the position of the part, and it is not easy to control its hanging posture outside the wire harness entrance of the rubber coating mechanism.

[0070] In addition, the above-mentioned tape holding rod slide 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 is suspended outside the wire harness entrance of the rubber coating 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 can also adopt other tape pressing parts other than round rods, such as thin flat plates, grid plates, wavy dot plates, etc. Such plates can press the tape on the tape support surface 306 with a smaller contact area, and can also play a role of temporary fixing. However, since the pressure is applied in the form of a plate body, the plate body itself cannot rotate, so when the tape moves upward, it will have a certain impact on its sticky surface.

[0071] In addition, the tape retaining rod slide 304 can also be replaced by other adjustment components that drive the tape retaining rod 305. For example, it can be replaced by other sliding parts, as long as the sliding part and the rubber-coated module base 301 form a sliding pair that adjusts the distance between the tape pressing part and the tape supporting surface 306.

[0072] In another embodiment, the temporary fixing mechanism of the tape can also be realized by a negative pressure suction structure, that is, a negative pressure suction port is opened on the tape supporting surface 306, and a negative pressure suction device is connected. When the tape passes through the negative pressure suction port, the tape can be sucked onto the tape supporting surface 306 by negative pressure suction. The size of the bonding force can be controlled by adjusting the size of the negative pressure, thereby conveniently controlling the fixing and release of the tape.

[0073] like Figure 3 As shown, the adhesive tape feeding module 4 is composed of: an adhesive tape feeding module base 401, a linear motion module 402, a film reel 403, a tape roll 404, a tape guide roller 405, a tape delivery wheel assembly 406, a pair of scissors 407, and an untied adhesive tape 408. The adhesive tape feeding module base 401 is the base part of the module, on which various functional parts are arranged; the adhesive tape feeding module base 401 is connected to the slider of the linear motion module 402. The linear motion module 402 is arranged in a vertical direction, and the slider can move in the vertical direction; a film reel 403 is arranged above the module base 401, and the adhesive tape roll 404 used for work can be installed on the film reel 403. The untied adhesive tape 408 bypasses the adhesive tape guide roller 405 in the direction shown in the figure, and bypasses the two rollers of the adhesive tape delivery wheel assembly 406, and then extends downward and passes through the cutting position of the scissors 407. As shown in FIG. Figure 3 As shown, the untied tape 408 and the tape roll are installed in such a way that the non-sticky surface of the tape contacts the surface of the tape guide roller 405, and the sticky surface 409 of the tape contacts 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 stickiness between the tape and the tape. Moreover, the two rollers are arranged staggered up and down and rotate at a differential speed. The rotation speed of the upper roller is lower than that of the lower roller. After the tape is untied from the tape roll 404 under the rotation of the upper roller, it continues to be conveyed to the side of the lower roller. Since the rotation speed of the lower roller is faster, the sticky surface 409 of the tape can be detached from the surface of the upper roller in time, and then conveyed vertically downward under the action of gravity. Since the length of the tape is fixed during the wiring harness encapsulation process, the tape conveying wheel assembly 406 should convey the untied tape at a fixed length after pulling (untying) the tape roll, which can be achieved by controlling the rotation angle of the roller by servo. When the adhesive tape is delivered to a specific position, the adhesive tape can be cut by controlling the scissors 407 to form an independent adhesive tape segment.

[0074] Similarly, the adhesive tape feeding module 4 is only one of the implementation forms. In other embodiments, the linear motion module 402 can adopt any device that can realize vertical lifting, but its control accuracy should meet the requirements. In addition, the scissors 407 can also be replaced by other adhesive tape cutting mechanisms, such as laser cutting equipment. In some special cases, the adhesive tape can also be replaced by other sources of adhesive tape besides the adhesive tape roll 404, and the film reel 403 is not required. In addition, in addition to the above-mentioned double roller design, the adhesive tape conveying wheel assembly 406 can also adopt other existing adhesive tape conveying equipment, as long as it can realize the fixed length conveying of adhesive tape.

[0075] like Figure 4 As shown, the harness clamping module 5 is composed of: a clamping module base 501, a wire clamping support 502, a synchronous gear 503, a wire clamping assembly 504, a flexible polyurethane block 505, and a harness tensioning cylinder 506. In order to make the harness clamping position as close to the front of the equipment as possible, the harness clamping module is configured as a frame structure as shown in the figure, allowing the rubber coating module 3 at the rear to pass through the middle to the harness clamping position for rubber coating. 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 coating module 3 to extend into. The wire clamping assembly 504 is arranged at the front end of the module and is distributed on both sides of the clamping module base 501. The wire clamping assembly 504 is a positioning clamping part of the harness, which can be in the form of a clamping claw, a wire clamping arm, etc. Since the wire clamping assembly 504 is generally made of metal material, it is easy to cause damage to the wire harness when its clamping force is too large. Therefore, the clamping part of the wire clamping assembly that contacts the wire harness is preferably inlaid with a flexible polyurethane block 505. The purpose is to only allow the flexible polyurethane surface to contact the wire harness surface when clamping the wire harness surface to prevent the wire skin from being clamped. Of course, the flexible polyurethane block can also be replaced by other flexible protective parts. If there are other ways to prevent damage to the wire harness, the flexible protective part can also be omitted. The left and right wire clamping assemblies 504 are respectively installed on the left and right wire clamping supports 502. A certain distance should be maintained between the two. In order to ensure that the wire harness remains in a tensioned state during rubber coating, a tensioning mechanism should be used to control the horizontal distance between the wire harness clamping positions on the two wire clamping assemblies 504.

[0076] In the present device, the tensioning mechanism is a synchronous tensioning mechanism, which can control the left and right clamping supports 502 to drive the two clamping components 504 to press Figure 5The synchronous tensioning mechanism is composed of a clamping module base 501, a clamping support 502, a synchronous gear 503 and a harness tensioning cylinder 506. The ends of the horizontal parts of the clamping supports 502 on the left and right sides are respectively provided with spur rack structures with the same structural parameters. The horizontal part of the clamping support 502 and the top of the clamping module base 501 form a sliding pair. Two spur rack structures are arranged at intervals on both sides of the synchronous gear 503 and are respectively meshed with the synchronous gear 503. A wire harness tensioning cylinder 506 is fixed on one of the wire clamping supports 502, 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 pushed out, it can push the wire clamping support 502 where it is located away from the clamping module base 501, and under the synchronous transmission of the synchronous gear 503, the two wire clamping supports 502 can increase the distance in opposite directions at the same sliding rate, thereby driving the wire harnesses clamped on the two wire clamping assemblies 504 to be synchronously tensioned on both sides. Of course, in addition to the above-mentioned implementation forms, the gear power mechanism that drives the synchronous gear 503 can also be implemented by a motor or the like in addition to a cylinder. The synchronous drive device that drives the two wire clamping supports 502 can also be implemented by a similar connecting rod mechanism, or by using two cylinders to synchronously drive the wire clamping supports 502 on both sides separately, as long as the tensioning of the wire harness can be achieved. The tensioning mechanism can also be asynchronous tensioning on both sides, but synchronous tensioning is preferred.

[0077] Based on the above Figures 1 to 5 , showing a preferred implementation form of the wire harness tape equipment of the present invention. Since the equipment arranges the clamping position of the wire harness at the front end of the equipment as much as possible, it is convenient to be as close to the ultrasonic welding machine as possible when integrated into the ultrasonic welding station. Moreover, the rubber coating operation process adopts the wire harness clamping and the rubber coating module moves 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 separation design, which maintains independent operation in terms of working rhythm and does not cooperate with other rhythm actions to improve the stability and reliability of tape feeding.

[0078] Figure 6The figure shows the arrangement of the above-mentioned wire harness tape equipment combined with the ultrasonic welding machine 6 of the present invention. As can be seen from the figure, in the wire harness tape equipment, the wire harness clamping module 5 is arranged at one end close to the ultrasonic welding machine 6, and the tape feeding module 4 is arranged at one end away from the ultrasonic welding machine 6. Therefore, the wire harness clamping position of the wire harness tape equipment can be arranged so as to be very close to the wire harness welding position, and the distance A required to move between the welding state wire harness 7 and the clamping state wire harness 8 becomes very small. The above structure arrangement improves the feasibility of integrating the tape machine into the ultrasonic welding station, and satisfies the operator to operate two devices at the same time, and complete the welding and tape work of the wire harness in the same station in sequence. Due to the reasonable design of the equipment structure, it has little effect on the original ultrasonic welding work rhythm, and can also use the original waiting time during welding to complete the tape wrapping work of the welded wire harness, which plays the role of one person with two machines, reduces the on-site personnel configuration of the wire harness manufacturer, reduces the intermediate logistics and transportation links, and truly achieves the reduction of staff and increase of efficiency, reduces production costs, and improves production efficiency. Moreover, the layout of the equipment is also very flexible, and no additional workbench modification is required, and the old workbench of the wire harness manufacturer can be used as much as possible.

[0079] Figure 7 The figure shows that when the above-mentioned wire harness rubber tape equipment of the present invention is working, when the rubber tape module 3 moves forward to the rubber tape position to work, the wire harness remains stationary and does not cause the problem of secondary movement (pulling).

[0080] Figure 6 The integrated device workflow shown is described below:

[0081] The equipment workflow is divided into the following four steps:

[0082] 1. Prepare adhesive tape: Figure 8 As shown in the figure, the rubber-wrapping module 3 is in the waiting position, the linear motion module 402 of the adhesive tape feeding module 4 drives the feeding module to move downward to a suitable position, and the holding rod slide 304 moves forward, so that the adhesive tape holding rod 305 is a certain distance away from the adhesive tape holding surface 306 (so that the adhesive tape can pass smoothly, and the greater the distance, the better in theory). Then the adhesive tape conveying wheel group 406 starts to rotate, as shown in the figure. Fig. 9 As shown, while untying the tape, the untied tape passes through the space between the tape holding rod 305 and the tape holding surface 306, and is transported to the front position of the tape pre-pressing roller of the rubber-wrapping module 3, and the length of the tape output (dispensing) is controlled according to the set value. Fig.10 In the state shown, after the tape is spit out to the set length, the holding rod slide 304 moves backward, so that the tape holding rod 305 presses the tape tightly against the tape holding surface 306. Then, the linear motion module 402 drives the feeding module to move upward, driving the tape head to adjust to a suitable position, such as Fig.10 shown. Fig.11As shown, the scissors are started to cut the tape, and after the tape is cut, the linear motion module 402 drives the feeding module to move upward to the initial state. All related parts are restored to their original positions, and the tape preparation is completed.

[0083] 2. Manual wiring: The operator welds the wire harness with 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 wrapping device. The wire harness clamping module 5 automatically clamps the wire harness and automatically tightens it to both sides to keep the wire harness in a relatively ideal posture. Figure 6 shown.

[0084] 3. Automatic rubber coating: After the wire harness is clamped and tensioned, the rubber coating module 3 moves forward to the rubber coating position, such as Figure 7 In the initial stage of the rubber encapsulation module moving forward, the retaining rod slide 304 also moves slightly forward by a distance B, as shown in FIG. Fig.12 As shown, the purpose is to make the tape strip 9 to be wrapped separate from the tape holding surface 306 and only stick to the surface of the tape holding rod 305 by its own viscosity; as the rubber wrapping module 3 moves further forward, the wire harness tensioned at the clamping position first contacts the adhesive surface of the tape, as shown in FIG. Fig.12 As shown in the figure, under the pressing action of the upper and lower tape pre-pressing rollers, the tape is pre-wrapped on the surface of the wire harness; Fig.13 In the state shown, the rubber coating module 3 stays at the center of rotation of the rubber coating wheel 302 of the wiring harness. At this time, after the pressing action of the front rubber coating pre-pressing roller, the rubber coating has pre-wrapped the first circle to the wiring harness surface; then the motor is started to drive the rubber coating wheel 302 to rotate continuously, and under the pressing action of the upper and lower rubber coating springs 303, the remaining rubber coating is coated on the wiring harness surface. The shape of the wrapped rubber coating 10 is shown in Figure 14. After the automatic rubber coating process is completed, the rubber coating module 3 returns to the initial position, and the rubber coating conveying module descends again to enter the rubber coating material preparation cycle.

[0085] 4. Manual offline: The operator manually removes the wrapped wire harness and replaces it with a new unwrapped wire harness.

[0086] Of course, the device of the present invention is not only developed specifically for the above-mentioned integration with the ultrasonic welding machine station, but the unique structural form and working mode of the device are very suitable for the working mode of integration with the ultrasonic welding machine. In addition to the ultrasonic welding machine, other wire harness connection devices for electrically connecting the wires that need to be wired together in the wire harness can also be integrated with the wire harness tape wrapping device of the present invention, such as other wire harness welding equipment or wire harness riveting equipment.

[0087] Of course, as an automatic tape wrapping device, the present invention has the basic functions of traditional similar devices and can also be used alone in a conventional independent wire harness tape wrapping station.

[0088] It can be seen that the present invention has the basic functions of conventional rubber coating equipment and takes into account the independent use of independent rubber coating stations. When the wire harness rubber coating equipment of the present invention is integrated and applied to the ultrasonic welding station, due to the reasonable design of the equipment structure, the operator can take into account the operation of two devices at the same time, and the original ultrasonic welding work rhythm is not greatly affected, which plays the role of one person with two machines and improves production efficiency.

[0089] The above-described embodiment is only a preferred solution of the present invention, but it is not intended to limit the present invention. A person skilled in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
