Description

TECHNICAL FIELD

[0001] The application belongs to the field of wire harness production automation equipment, and particularly relates to a compact head module and method capable of automatically completing tape preparation, pre-adhesion, winding and cutting. BACKGROUND

[0002] With the rapid development of new energy vehicles, the automation requirement of related wire harness production is higher and higher. Different from the wire harness design of traditional fuel vehicles (small wire diameter, multiple branches, complex structure and the like which are not conducive to the implementation of automatic production), the wire harness design of new energy vehicles is more inclined to and more conducive to realizing the production mode of full automation line. However, the traditional semi-automatic tape winding equipment has been difficult to meet the use requirement in the aspect of full automation (such as robot tape wrapping, integrated tape winding link in automatic flow line and the like). Based on the common knowledge of those skilled in the art, the tape winding process includes tape head pre-adhesion, continuous winding stage, tape cutting and tape tailing and the like. The existing semi-automatic tape winding equipment only better completes the work of continuous winding stage, and the pre-adhesion of tape, the tailing and cutting of tape and the like still need to rely on manual intervention of operators, which makes the tape winding become a bottleneck link of wire harness full automation production. Because for a considerable part of new energy wire harness, the upstream and downstream process links of tape winding have been well realized in the aspect of automatic production rhythm, and only the tape winding link (continuous winding) fails to well connect the upstream and downstream.

[0003] Some equipment manufacturers in the industry have also tried to develop equipment modules capable of automatically completing tape preparation, tape pre-adhesion, continuous winding and cutting. From the independent functions, the full automation action process is indeed realized. However, the existing technology is only a simple splicing design of various functional structures, which is a non-standard and non-modular design. The application in some simple links is not a problem. However, the main problems are: 1. The structure design is bloated, and a large equipment space is occupied. In particular, the transverse design size (static and dynamic) is too large, which occupies too much tape winding space, causes the starting position and ending position of tape winding to be too far away from the wire connector or intermediate branch node, and does not meet the design requirements; 2. The non-standard and non-modular design structure is difficult to transplant and apply, lacks universality, and needs to be re-designed and arranged for another application link; 3. Due to the bloated structure design, the weight is also correspondingly large, and in the application link of robot tape wrapping, a larger size mechanical arm needs to be selected to support, which increases the corresponding application cost.

[0004] Therefore, in the industry, there is an urgent need for a tape winding equipment with compact structure, stable performance and capable of automatically completing tape preparation, winding and cutting. SUMMARY

DETAILED DESCRIPTION

[0051] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below. The technical features in each embodiment of the present application can be combined accordingly without conflict.

[0052] In the description of the present application, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element with an intermediate element. In contrast, when an element is considered to be "directly" connected to another element, there is no intermediate element.

[0053] In the present application, in order to facilitate the description, the positional relationship of each component is described with reference to the device orientation shown in Figure 1 , wherein "front" and "rear" respectively refer to the right side and left side in Figure 1 , and "upper" and "lower" respectively refer to the upper side and lower side in Figure 1 . Figure 1 The orientation of the device shown in Figure 2 is the front, and the orientation of the device shown in is the back. Unless otherwise specified, the positional relationship of the present application is described as above.

[0054] Figure 1 , and 2As shown, the full-automatic tape winding head module provided by the application mainly comprises a rotating wheel assembly 2, a jaw swing arm assembly and a tape automatic cutting mechanism which are installed on the module base 1. The on-line full-automatic winding tape function is realized by the cooperation of the mechanisms, and the cooperation process is described below.

[0055] In the device of the application, as shown in the figure, Figure 1 The rotating wheel assembly 2 is rotatably connected to the front part (i.e. the right side) of the module base 1, and the front end (i.e. the rightmost end) is provided with an opening. The opening serves as a passage to allow the wire harness 6 to enter the interior of the rotating wheel assembly 2. In actual use, the rotating wheel assembly 2 can wind the tape around the wire harness 6 by rotating, and the tape head clamping mechanism 210 can clamp the tape near the cutting position.

[0056] In the device of the application, as shown in the figure, Figure 1 The jaw swing arm assembly is located below the rotating wheel assembly 2 and can move up and down and rotate around the shaft, and the tape jaw assembly 7 can clamp the tape head.

[0057] In the device of the application, as shown in the figure, Figure 1 The tape automatic cutting mechanism is located at the rear part of the rotating wheel assembly 2. The tape cutter 17 can move between the tape cutting position and the avoiding position, and the tape cutter 17 can cut the tape at the breaking point at the tape cutting position.

[0058] In theory, the structure of the above-mentioned module base 1, rotating wheel assembly 2, jaw swing arm assembly and tape automatic cutting mechanism is not limited, as long as the functions described above can be realized.

[0059] The preferred implementation forms of the mechanisms will be described in detail below by way of examples in combination with the drawings.

[0060] The specific form of the above-mentioned module base 1 of the application can be adjusted according to actual needs. The module base 1 serves as the base body of the entire mechanism, and its main function is to provide the installation position of each functional mechanism. Considering the aesthetics and convenience, the module base 1 can be integrally provided as a square plate structure, the front part of which is gradually inwardly tapered and the frontmost end of which is provided with an opening along the vertical direction. The opening structure serves as the access passage for the wire harness. The front part of the module base 1 which is in communication with the opening is also provided with a circular hollow part for installing the rotating wheel assembly 2, so that the rotating wheel assembly 2 can be cooperatively rotated in the space of the circular hollow part. The main body structures of the jaw swing arm assembly and the tape automatic cutting mechanism are installed on the front side of the module base 1.

[0061] In a more preferred embodiment of the application, as shown in the figure, Figure 3As shown, the rotating roller assembly 2 is arranged at the front position of the module base 1, and is also an open structure, which can rotate. The rotating roller assembly 2 mainly comprises a rotating roller 201, a film fixing shaft 202, a tape guide roller 204, a tape deflection guide roller 205, a counterweight 208 and a tape head clamping mechanism 210.

[0062] Specifically, the rotating roller 201 is in an arc structure, and a transmission tooth is arranged on the outer periphery. Figure 1 As shown, the arc-shaped opening of the rotating roller 201 is the same size as the front end opening of the module base 1, and the two openings coincide in the initial state. Figure 2 As shown, the rotating roller 201 is connected in transmission with the rotating roller driving motor 18 through the rotating roller driving synchronous belt 19, thereby forming a belt transmission; the rotating roller 201 can be rotated at the front of the module base 1 through the rotating roller driving motor 18, thereby driving the tape roll 3 to move in a circular arc on the front face of the module base 1.

[0063] As shown, Figure 3 The film fixing shaft 202 is fixed to the upper part of the rotating roller 201 through the film fixing support 203, the film fixing shaft 202 can coaxially fix the tape roll 3, and the tape roll 3 can rotate together with the film fixing shaft 202 along the central axis. The tape guide roller 204 and the tape deflection guide roller 205 are both fixed to the upper part of the rotating roller 201, and the tape guide roller 204 and the tape deflection guide roller 205 are both located below the film fixing shaft 202. Figure 1 and 5 As shown, the tape 4 unwound from the tape roll 3 can pass through the tape guide roller 204 and the tape deflection guide roller 205 in turn under the guidance of the tape guide roller 204 and the tape deflection guide roller 205, and the adhesive surface 4a of the tape faces the opening of the module base 1. The counterweight 208 is located at the lower part of the rotating roller 201, which can balance the gravity of each mechanism at the upper part of the rotating roller 201, facilitate the rotation of the rotating roller 201 and return to the initial state.

[0064] As shown, Figure 3 The tape deflection guide roller 205 is fixed to the tape deflection support seat 207 through the tape deflection support 206, and the tape deflection support seat 207 is fixed to the upper part of the rotating roller 201. The tape deflection support 206 has a flexible deflection amount, which can make the tape deflection guide roller 205 rotate in deflection in actual use, so as to adapt to the conveying direction of the unwound tape 4, and make the tape deflection guide roller 205 always have a guiding effect on the tape.

[0065] The rotating wheel assembly 2 of the present application is provided with a conventional film fixing shaft 202, a film fixing support 203, a film guide roller 204, a film deflection guide roller 205, a film deflection support 206, a film deflection support seat 207, a counterweight 208 and other conventional functional components, and further comprises a film head clamping mechanism 210. The film head clamping mechanism 210 functions to temporarily maintain the posture of the film near the breakage before the film is disconnected when a film winding process is completed, to prevent the film head from retracting and drifting after the film is disconnected, and to enable the subsequent film clamping mechanism to further reliably clamp the film head and prepare the film for the next process. The conventional film head clamping mechanism is externally provided on the rotating wheel assembly, and is temporarily clamped at the film maintaining position before the film is cut. Since the external clamping mechanism and the rotating range of the rotating wheel assembly interfere with each other, the external clamping mechanism needs to be withdrawn from the rotating range in advance during the winding process, and the space occupied by the advancing and retreating path of the mechanism greatly affects the minimum distance between the winding start and end positions of the film and the connector or branch pivot. The film head clamping mechanism 210 is innovatively integrated on the rotating wheel assembly 2, which solves the above problems.

[0066] Specifically, as shown in Figure 4 the film head clamping mechanism 210 mainly comprises a driven side film clamping arm 211, a clamping arm synchronous gear 212, a clamping arm guide rail 213 and a driving side film clamping arm 214. Specifically, the clamping arm guide rail 213 is fixed to the upper part of the rotating wheel 201, and the driven side film clamping arm 211 and the driving side film clamping arm 214 are respectively connected to the clamping arm guide rail 213 through sliding blocks. The inner sides of the driven side film clamping arm 211 and the driving side film clamping arm 214 are provided with toothed structures, and the two are respectively engaged with the clamping arm synchronous gear 212 to be coupled into a linkage structure. That is, as long as the external mechanism (such as the film clamping mechanism driving cylinder 21 shown in Figure 2 can drive one side of the clamping arm, the driven side film clamping arm 211 and the driving side film clamping arm 214 can be simultaneously driven to move towards each other. Since the film head clamping mechanism 210 moves together with the rotating wheel assembly 2, the external driving mechanism can only provide power in the clamping direction.

[0067] In actual use, the output end of the film clamping driving cylinder 21 fixed on the module base 1 drives the driving side film clamping arm 214 to slide along the clamping arm guide rail 213, causes the clamping arm synchronous gear 212 to mesh and rotate, drives the driven side film clamping arm 211 to slide along the clamping arm guide rail 213, and causes the driven side film clamping arm 211 and the driving side film clamping arm 214 to move towards each other. As shown in Figure 2As shown, the tape clamping drive cylinder 21 can be fixed to the back of the module base 1. The driven side tape clamping arm 211 and the drive side tape clamping arm 214 are located below the tape deflection guide roller 205, and can clamp the vertical unwound tape 4 from both sides. In actual use, the clamping arm synchronous gear 212 can be rotated and fixed to the driving wheel 201.

[0068] In order to meet the return purpose of the tape clamping mechanism 210 in the normal state, a tape clamping return spring 209 is also provided. Specifically, the drive side tape clamping arm 214 is fixed with one end of the tape clamping return spring 209, and the other end of the tape clamping return spring 209 is fixed with the driving wheel 201 located outside the drive side tape clamping arm 214 (here, the outside refers to the side away from the driven side tape clamping arm 211), so that the drive side tape clamping arm 214 stretches the tape clamping return spring 209 when it moves. When it is necessary to reset the driven side tape clamping arm 211 and the drive side tape clamping arm 214 to the loosened state, the drive side tape clamping arm 214 is driven to move outward under the action of the elastic force, and the clamping arm synchronous gear 212 is rotated in the movement process of the drive side tape clamping arm 214, so that the driven side tape clamping arm 211 is synchronously moved outward, and then the driven side tape clamping arm 211 and the drive side tape clamping arm 214 are separated and restored to the original position (i.e. the loosened state).

[0069] In a preferred embodiment of the present application, as shown in Figure 1 The jaw swing arm assembly is arranged directly below the tape roll rotation range, mainly including a tape jaw assembly 7, a tape jaw cylinder 8, a jaw swing arm 9, a jaw swing arm base 10, a jaw swing arm cylinder 13 and a jaw swing arm guide rail 14. The jaw swing arm assembly has two functions: 1. It can be used as a maintaining mechanism for the tape head posture in the initial state and the tape pre-sticking stage; 2. It can be used as a clamping mechanism for the tape in the tape preparation stage.

[0070] Specifically, the jaw swing arm guide rail 14 is vertically fixed to the rear of the module base 1 and located on the front of the module base 1, and the jaw swing arm base 10 is slidably connected to the jaw swing arm guide rail 14 through a sliding block. As shown in Figure 2 The back of the module base 1 is fixed with a jaw swing arm drive motor 20, as shown in Figure 1 The output end of the jaw swing arm drive motor 20 is provided with a jaw swing arm drive gear 12, and the jaw swing arm base 10 is vertically provided with a jaw swing arm drive rack 11. The jaw swing arm drive gear 12 is in meshing connection with the jaw swing arm drive rack 11. In actual use, the jaw swing arm base 10 can be driven to slide up and down along the jaw swing arm guide rail 14 by the jaw swing arm drive motor 20.

[0071] The clamping jaw swing arm base 10 is provided with a clamping jaw swing arm 9 and a clamping jaw swing arm cylinder 13. One end of the clamping jaw swing arm 9 is rotationally connected to the clamping jaw swing arm base 10, and the other end is provided with a tape clamping jaw assembly 7. The tape clamping jaw assembly 7 is located below the tape deflection guide roller 205 and can clamp or release the tape head under the drive of the tape clamping jaw cylinder 8.

[0072] In the embodiment, the tape clamping jaw assembly 7 mainly includes a driven side tape clamping jaw 7a and a driving side tape clamping jaw 7b. The driven side tape clamping jaw 7a and the driving side tape clamping jaw 7b are both provided with a toothed structure and are meshingly connected. The lower end of the driving side tape clamping jaw 7b is rotationally connected to the output shaft of the tape clamping jaw cylinder 8, and the lower end of the driven side tape clamping jaw 7a is rotationally connected to the end of the clamping jaw swing arm 9. The driven side tape clamping jaw 7a and the driving side tape clamping jaw 7b can be clamped or released under meshing transmission by the tape clamping jaw cylinder 8. In addition, the tape clamping jaw cylinder 8 can be installed on the clamping jaw swing arm 9 and can rotate synchronously with the clamping jaw swing arm 9.

[0073] One end of the clamping jaw swing arm cylinder 13 is rotationally connected to the clamping jaw swing arm base 10, and the other end (i.e. the output end) is connected to the middle part of the clamping jaw swing arm 9. In actual use, the clamping jaw swing arm 9 can be driven to swing up and down with the hinge point (i.e. the connection end of the clamping jaw swing arm 9 and the clamping jaw swing arm base 10) as the fulcrum, so that the tape clamping jaw assembly 7 can avoid the rotation range of the rotating drum assembly 2 in the tape winding stage, and can swing up to the required position in the tape holding stage, tape clamping stage, etc. During operation, in combination with the up and down swinging of the clamping jaw swing arm 9, the tape clamping jaw assembly 7 ultimately realizes the switching among the tape head clamping position, the tape initial state holding position, and the tape winding stage avoidance position.

[0074] In a preferred embodiment of the present application, as shown in Figure 1 The tape automatic cutting mechanism mainly includes a tape cutter seat 15, a tape cutter guide rail 16 and a tape cutter 17.

[0075] Specifically, the tape cutter guide rail 16 is axially (i.e. Figure 1The tape cutter holder 15 is arranged horizontally (left and right) and is located at the rear of the rotating wheel assembly 2. The upper end of the tape cutter holder 15 is slidably connected to the tape cutter guide rail 16 via a slider, and the tape cutter holder 15 can slide horizontally left and right along the tape cutter guide rail 16 under the drive of the drive device. A tape cutter 17 is fixed at the bottom of the tape cutter holder 15, with the blade of the tape cutter 17 facing forward. Under the drive of the drive mechanism, the tape cutter 17 can move between the cutting position and the avoidance position. When the tape cutter holder 15 moves the tape cutter 17 to the right to the tape cutting position (generally when the tape cutter holder 15 moves to the right limit position of the tape cutter guide rail 16), the tape cutter 17 can cut the tape located between the tape head clamping assembly 210 and the tape gripper assembly 7. In this embodiment, the tape cutter 17 has a pointed blade structure, which, in conjunction with the clamping action of the tape head clamping mechanism 210, can quickly and reliably cut the tape.

[0076] Using the aforementioned fully automatic tape wrapping head module, this invention also provides an operating method, which is as follows:

[0077] S1: Initial preparation stage, such as Figure 5 As shown, the details are as follows:

[0078] The opening of the driving wheel 201 is aligned with the opening of the module base 1 to facilitate the entry and exit of the wire harness 6. The tape roll 3 is coaxially sleeved on the tape roll fixing shaft 202. The tape 4 unwound from the tape roll 3 passes sequentially through the tape guide roller 204 and the tape sway guide roller 205, so that the adhesive surface 4a of the tape faces the opening side of the module base 1. The swing angle of the gripper swing arm 9 is adjusted by the gripper swing arm cylinder 13 so that the unwound tape head is clamped and fixed in a suitable position by the tape gripper 7. The tape cutter 17 is in a rear clearance position of the module base 1. The driven side tape gripping arm 211 and the driving side tape gripping arm 214 are in the initial open state.

[0079] S2: Tape pre-adhesion stage, such as Figure 6 and Figure 7 As shown, the details are as follows:

[0080] like Figure 6 As shown, the wire harness 6 first passes through the opening at the front end of the module base 1 and moves to the center of rotation of the rotating wheel 201. At this time, the outer surface of the wire harness 6 contacts the adhesive surface 4a of the tape to form a preliminary pre-adhesion, but it is not yet a reliable pre-adhesion. Subsequently, as... Figure 7 As shown, the moving wheel 201 rotates in the winding direction by as large an angle as possible, with the rotation range of the angle ensuring that it does not obstruct the downward swing of the gripper arm 9. At this time, the pre-adhesion wrapping angle between the outer surface of the wire harness 6 and the adhesive surface 4a of the tape increases, thereby increasing the reliability of the tape pre-adhesion.

[0081] S3: Tape wrapping and coating stage, such as Figure 8 andFigure 9 As shown, the details are as follows:

[0082] First, the tape gripper cylinder 8 releases the tape head from the tape gripper assembly 7. Then, the gripper swing arm cylinder 13 swings the gripper swing arm 9 downwards, causing the tape gripper assembly 7 to exit the tape winding rotation range. The drive wheel motor 18 drives the drive wheel 201 to rotate in the tape wrapping direction. Simultaneously, the head module moves relative to the wire harness 6 along its axial direction, creating a spiral tape wrapping effect, ultimately resulting in the fully wound tape 5.

[0083] During this process, the belt sway guide roller 205 can sway and rotate to adapt to the belt conveying direction, and always guide the untied belt 4.

[0084] S4: Tape finishing and cutting stage, such as Figure 10 As shown, the details are as follows:

[0085] After the continuous winding stage ends and the tape roll 3 returns to its initial state, the tape clamping drive cylinder 21 externally drives the drive-side tape clamping arm 214 to slide along the clamping arm guide rail 213, causing the driven-side tape clamping arm 211 and the drive-side tape clamping arm 214 to move closer to each other and clamp the tape above the cutting position. Subsequently, the tape cutter holder 15 drives the tape cutter 17 to move along the tape cutter guide rail 16 to the tape cutting position, cuts the tape, and then retracts.

[0086] S5: Tape preparation stage, such as Figure 11 and 12 As shown, the details are as follows:

[0087] After the wire harness 6, wrapped with tape, exits the head module through the front opening of the module base 1, the tape preparation stage begins. At this time, the tape gripper assembly 7 remains open, and the gripper swing arm cylinder 13 actuates to swing the gripper swing arm 9 upwards to a horizontal position. Simultaneously, the gripper swing arm drive motor 20 drives the gripper swing arm drive gear 12 to rotate, driving the gripper swing arm base 10 upwards until the tape gripping position (e.g., ...). Figure 11 (State), causing the cut end of the tape to enter the opening position of the tape gripper assembly 7. For example... Figure 12 In the indicated state, the tape gripper cylinder 8 actuates to close the tape gripper assembly 7, clamping the tape head. Subsequently, the tape gripping drive cylinder 21 resets, and the tape gripping return spring 209 separates the driven-side tape gripping arm 211 from the driving-side tape gripping arm 214. Next, the gripper swing arm drive motor 20 actuates again, driving the gripper swing arm base 10 downwards, causing the tape gripper assembly 7 to move downwards with the tape head to the initial preparation stage position of S1, completing the tape preparation stage.

[0088] In actual use, S1-S5 can be repeated multiple times as needed to achieve full-automatic tape winding of each target harness 6.

[0089] The design principle of the device of the present application is briefly described as follows:

[0090] In the prior art, the tape roll is mounted on a rotating dynamic wheel with an opening arranged thereon, the opening of the dynamic wheel allows the harness to enter the rotating center position of the dynamic wheel; at the same time, the unwound part of the tape passes through a set of guide rollers to reach the winding position at the center of the rotating dynamic wheel; when the tape head has been reliably pre-adhered to the surface of the harness, the motor drives the rotating dynamic wheel to rotate around the harness for rotating and winding movement, and the head module moves relatively along the axial direction of the harness to uniformly and controllably wind the tape onto the surface of the harness; when the tape is wound to the tail, a mechanism or manual operation is required to cut the tape.

[0091] However, the above basic tape winding process and structure cannot arrange corresponding mechanisms in the space of the tape roll and the rotating range of the dynamic wheel to realize the corresponding functions. The existing full-automatic winding technical solution only simply arranges corresponding mechanisms outside the above rotating space to realize actions such as pre-adhesion and cutting. Therefore, how to more reasonably, compactly and ingeniously design and arrange mechanisms with corresponding functions becomes a key factor in the design.

[0092] The core of the design scheme of the present application is:

[0093] 1. Since the dynamic wheel is an open dynamic rotating body, a conventional power mechanism cannot be arranged thereon, and the present application ingeniously arranges a set of tape head clamping mechanisms on the rotating dynamic wheel assembly. When the dynamic wheel is at a specific position, the action of the tape head clamping mechanism is pushed by an external mechanism, and this specific position coincides with the position where the tape head clamping mechanism needs to act. This avoids the extra space caused by the need to avoid the tape roll and the rotating space of the dynamic wheel when arranging the tape head clamping mechanism externally, and reduces the structure size of the head module.

[0094] 2. Before the tape is pre-adhered and wound, a mechanism is arranged to maintain the posture of the tape, avoiding unstable posture of the tape head, thereby improving the reliability of each pre-adhesion of the tape, and the maintaining mechanism can be automatically avoided during the tape winding stage.

[0095] 3. An automatic tape cutting mechanism is arranged, which, in cooperation with the above-mentioned tape head clamping mechanism, can complete the automatic cutting function of the tape after the tape winding is completed, and maintain the posture of the cut tape head, so that the tape clamping mechanism can further reliably clamp the tape, and the state of the tape is switched to the initial preparation state of the next winding process.

[0096] 4. The above-mentioned tape maintaining mechanism in the initial stage also serves as the tape clamping mechanism in the preparation stage of the tape, so that one set of mechanism can complete different work contents in two stages, saving half of the corresponding mechanism arrangement.

[0097] 5. The tape automatic cutting mechanism, tape holding mechanism / tape clamping mechanism are arranged outside the rotation space range of the movable wheel assembly, but not arranged in the rotation axial direction, but arranged outside the rotation range in the radial direction, which has the advantage of reducing the thickness size of the head module, and is beneficial to winding the tape closer to the wire harness connector or branch node position.

[0098] The above-described embodiments are only a preferred scheme of the present application, and are not intended to limit the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, any technical scheme obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
