Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing equipment, and in particular to a wire harness labeling machine. Background Technology

[0002] In modern manufacturing, wire harnesses, as an important component connecting various electronic devices and parts, are widely used in many fields such as automobiles, electronics, and communications. To facilitate the identification, management, and traceability of wire harnesses, labels need to be affixed to them. These labels typically contain information such as the wire harness's model, specifications, and production batch.

[0003] Patent CN221252087U discloses a wire harness labeling device, belonging to the field of labeling equipment technology. It includes a base and a fixing plate. The base is installed in the middle of the upper surface of a workbench. The fixing plate is connected to the top of the base. A rotating seat is installed on the inner side of the fixing plate. A rotating wheel is rotatably connected to the rotating seat via a rotating shaft. A clamping plate is connected to the rotating wheel. Wire harness grooves are symmetrically arranged on the fixing plate and the clamping plate. A gear is coaxially connected to the rotating shaft connected to the rotating wheel. An electric push rod is installed at the bottom of the workbench. The movable rod of the electric push rod passes through the workbench, and a rack is connected to the upper end of the movable rod. The rack meshes with the electric push rod. A control pedal is installed on the ground below the workbench and is electrically connected to the control circuit of the electric push rod. When in use, the worker first places the label in the label slot with the adhesive side facing up. Then, the end of the wire harness is placed into the wire harness slot of the fixing plate after it comes into contact with the positioning plate. During the placement process, the label is pressed into the wire harness slot along with the wire harness. Afterward, the worker steps down the control pedal to power up the electric push rod and push the rack upward. Through the meshing transmission between the rack and the gear, the clamping plate is driven to flip and close with the fixing plate.

[0004] The aforementioned patent document discloses a labeling device in which technicians manually place labels onto a clamping plate and then control the opening and closing of the clamping plate via a foot pedal, thereby labeling the wire harness. However, this technical solution suffers from the following problems: First, while the method of labeling using a rack and pinion transmission improves efficiency compared to traditional manual labeling, it still relies heavily on manual operation and cannot meet the demands of large-scale production, resulting in a long production cycle. Second, human fatigue can lead to irregular label placement, affecting the label's aesthetics and readability, which may consequently impact the quality and usability of the wire harness, and could even cause injury due to improper operation. Furthermore, manual operation is prone to human error, leading to discrepancies between the label information and the actual condition of the wire harness, causing inconvenience for subsequent management and use.

[0005] Therefore, there is an urgent need for an efficient, accurate, and stable automated wire harness labeling device. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a wire harness labeling machine that is highly automated, accurate, aesthetically pleasing and efficient in labeling.

[0007] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0008] A wire harness labeling machine includes a worktable; a label removal device perpendicular to the worktable, comprising a pressing assembly for pressing the label tape and a peeling knife assembly for peeling the label from the base tape, arranged sequentially along the feeding direction; the label tape consists of a base tape and a label adhered to the base tape; a wire frame rotatably mounted on the worktable for fixing the wire harness; a labeling device mounted on the worktable opposite to the wire frame, comprising a movable plate extending toward the wire frame and slidably mounted on the worktable and a clamping assembly mounted on the movable plate; the clamping assembly includes a mounting frame arranged along the length of the movable plate and a clamping plate structure mounted on the mounting frame and facing the wire clamp; and a take-up roller perpendicular to the worktable for winding the base tape.

[0009] To achieve the above technical solution, the clamp assembly reciprocates along the length of the moving plate, enabling the clamp assembly to reciprocate between the wire frame and the label removal device. In conjunction with the rotatable automatic feeding wire frame, automated labeling of the wire harness is achieved, improving labeling efficiency and accuracy while reducing labor costs.

[0010] Furthermore, the clamping structure includes a fixed plate mounted on the end of the mounting frame facing the wire frame, a pair of adsorption plates arranged opposite each other and rotatably mounted on the fixed plate, a first driving cylinder for driving the adsorption plates to rotate, and a connecting rod for connecting the adsorption plates and the output end of the first driving cylinder; the two ends of the connecting rod are respectively hinged to the adsorption plates and the output end of the first cylinder.

[0011] To achieve the above technical solution, the reciprocating motion of the output end of the first drive cylinder drives the connecting rod to move, which in turn drives a pair of oppositely arranged adsorption plates to open or close, thereby realizing the functions of picking up labels and folding and attaching labels.

[0012] Furthermore, the fixing plate is provided with a receiving groove for the wire harness to pass through. The receiving groove is located between a pair of adsorption plates and is parallel to the plane formed after the adsorption plates are closed.

[0013] To achieve the above technical solution, the receiving groove is used to hold the wire harness to be labeled, so as to prevent the adsorption plate from pinching the wire harness when it is closed, thereby damaging the wire harness.

[0014] Furthermore, the receiving groove is provided with guide strips arranged along its length.

[0015] The above technical solution provides an accurate stopping position for the wire harness, ensuring that each wire harness entering the receiving slot remains in the same position, thereby enabling the clamping assembly to achieve precise labeling.

[0016] Furthermore, the clamping structure includes a second driving cylinder, which is located on both sides of the mounting frame, along with the first driving cylinder. The first driving cylinder is slidably connected to the mounting frame along its length, and its end away from the clamping structure is connected to the output end of the second driving cylinder via a connecting plate.

[0017] To achieve the above technical solution, the reciprocating motion of the output end of the second drive cylinder increases the displacement stroke of the first drive cylinder, thereby increasing the movement range and flexibility of the clamping assembly. Even when the size of the wire harness to be labeled changes, or the position of the wire frame changes, the clamping structure can still label the wire harness.

[0018] Furthermore, the peeling knife assembly includes a label removal knife with its blade facing the labeling device and vertically mounted on the worktable, and an adjusting roller located downstream of the label removal knife for bending the bottom strip; the side of the label removal knife facing the adjusting roller is inclined on a single slope, working in conjunction with the adjusting roller to peel the label off the bottom strip.

[0019] To achieve the above technical solution, the label removal blade is designed with a single-slope inclination on one side, which can effectively increase the bending degree of the base strip and better peel the label off the base strip.

[0020] Furthermore, the clamping assembly includes a support plate arranged parallel to the label removal knife and a clamping cylinder with an output end for abutting against the support plate; the output end of the clamping cylinder clamps the label to the bottom strip against the support plate.

[0021] By implementing the above technical solution, the situation where the label and the base tape do not detach when passing through the label removal knife can be avoided due to the gap between the label and the base tape.

[0022] Furthermore, it also includes a feeding roller that feeds material from itself toward the label removal device and a tensioning roller located between the feeding roller and the label removal device to provide tension for the label tape.

[0023] To achieve the above technical solution, the tensioning roller is used to tension the label tape being fed, so that the label tape can receive lateral tension when it passes through the label removal knife, making it easier for the label to detach from the bottom tape.

[0024] Furthermore, it also includes a receiving drive roller assembly located downstream of the label removal device along the label tape conveying direction; the drive roller assembly includes guide rollers, auxiliary rollers and drive rollers that are arranged parallel to each other and rotatably mounted vertically on the worktable; the drive rollers and auxiliary rollers are arranged close to each other to drive the bottom tape toward the receiving roller direction for receiving.

[0025] To achieve the above technical solution, the drive roller and the auxiliary roller are pressed tightly together to clamp the bottom belt, and the drive bottom belt is driven to take in the material in the direction of the take-up roller.

[0026] As described above, the wire harness labeling machine of this utility model has the following beneficial effects:

[0027] 1. By utilizing the sliding connection between the moving plate and the worktable, as well as the sliding connection between the clamping assembly and the moving plate, and in conjunction with the use of the drive cylinder, the automation level of the labeling machine is greatly improved.

[0028] 2. The use of two cooperating drive cylinders greatly improves the flexibility and applicability of the clamping assembly, thereby enhancing the flexibility and applicability of the labeling machine. Attached Figure Description

Detailed Implementation

[0033] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0034] Please see Figure 1-3It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0035] Please see Figures 1 to 3 This utility model provides a wire harness labeling machine 1000, including a worktable 1, a label removal device 2 and a wire frame 3 vertically arranged on the worktable 1, and a labeling device 4 rotatably arranged on the worktable 1. The label removal device 2 and the labeling device 4 are sequentially arranged on the worktable 1 along the label tape conveying direction; the labeling device 4 is arranged opposite to the wire frame 3 used to fix the wire harness; the label tape includes a base tape and a label adhered to the base tape.

[0036] Specifically, the label removal device 2 includes a pressing component 21 for pressing the label tape and a peeling component 22 for peeling the label tape off the bottom tape, which are arranged sequentially along the label tape feeding direction.

[0037] Furthermore, the labeling device 4 includes a movable plate 41 extending toward the wire frame 3 and slidably disposed on the worktable 1, and a clamping assembly 42 disposed on the movable plate 41. The clamping assembly 42 includes a mounting frame 421 disposed along the length of the movable plate 41 and a clamping plate structure 422 disposed on the mounting frame 421 and disposed toward the wire frame 3. The movable plate 41 extends toward the wire frame 3, and the clamping assembly 42 reciprocates along its length, enabling the clamping assembly 42 to reciprocate between the wire frame 3 and the label removal device 2. In conjunction with the rotatable automatic feeding wire frame 3, automated labeling of the wire harness is achieved, improving labeling efficiency and accuracy, and reducing labor costs.

[0038] In addition, the worktable 1 is also equipped with a take-up roller 8 for winding up the bottom strip. The take-up roller 8 is used to collect the bottom strip after the label is removed, so as to avoid the bottom strip from piling up on the worktable 1 and affecting the stable operation of the labeling machine.

[0039] Please continue reading. Figure 3The clamping structure 422 includes a fixed plate 4221 mounted on the mounting frame 421 at one end facing the wire frame 3, a pair of opposing suction plates 4222 rotatably mounted on the fixed plate 4221, a first driving cylinder 4223 for driving the suction plates 4222 to rotate, and a connecting rod 4224 for connecting the suction plates 4222 to the output end of the first driving cylinder 4223. The design of the suction plates 4222 ensures that the removed labels adhere tightly to the suction plates, and no air bubbles are formed after folding and attaching.

[0040] The two ends of the connecting rod 4224 are hinged to the adsorption plate 4222 and the output end of the first driving cylinder 4223, respectively. The reciprocating motion of the output end of the first driving cylinder 4223 drives the connecting rod 4224 to move, which in turn drives the pair of oppositely arranged adsorption plates 4222 to open or close, realizing the functions of picking up labels and folding and attaching labels.

[0041] Furthermore, the fixing plate 4221 is provided with a receiving groove 42211 for the wire harness to pass through. The receiving groove 42211 is located between a pair of adsorption plates 4222 and is parallel to the plane formed when the adsorption plates 4222 are closed. The receiving groove 42211 is used to accommodate the wire harness to be labeled, so as to prevent the adsorption plates 4222 from pinching the wire harness when closed, thereby damaging the wire harness.

[0042] Furthermore, the receiving groove 42211 is provided with a guide bar 4225 arranged along its length. The guide bar 4225 provides an accurate stopping position for the wire harness, ensuring that each wire harness entering the receiving groove 42211 is kept in the same position, thereby enabling the clamp assembly 42 to achieve accurate labeling.

[0043] Preferably, the clamping structure 422 further includes a second driving cylinder 4226, which is located on both sides of the mounting frame 421, along with the first driving cylinder 4223. The first driving cylinder 4223 is slidably connected to the mounting frame 421 via a guide rail 4211, and its end away from the clamping structure 422 is connected to the output end of the second driving cylinder 4226 via a connecting plate. The second driving cylinder 4226 is located on the other side of the mounting frame 421. The reciprocating motion of the output end of the second driving cylinder 4226 drives the first driving cylinder 4223 to move, increasing the displacement stroke of the first driving cylinder 4223, thereby increasing the movement range and flexibility of the clamping assembly 42. Even when the size of the wire harness to be labeled changes, or the position of the wire frame 3 changes, the clamping structure 422 can still label the wire harness.

[0044] Please continue reading. Figure 2The peeling blade assembly 22 includes a label removal blade 221 with its opening facing the labeling device 4 and vertically mounted on the worktable 1, and an adjusting roller 222 located downstream of the label removal blade 221 for bending the bottom strip. Specifically, the side of the label removal blade 221 facing the adjusting roller 222 is inclined on a single slope, working in conjunction with the adjusting roller 222 to peel the label off the bottom strip.

[0045] Specifically, the label removal blade 221 and the adjusting roller 222 are arranged in parallel. After the label tape passes through the blade, the label is attracted by the adsorption plate 4222, and the bottom tape is wrapped around the adjusting roller 222. The adjusting roller 222 adjusts the angle of the bottom tape so that the angle of the bottom tape before and after passing through the label removal blade 221 is greater than 180°. Preferably, the angle of the bottom tape before and after passing through the label removal blade 221 is greater than 135°, ensuring that the label can detach from the bottom tape when the label tape passes through the label removal blade 221 so that it can be attracted by the adsorption plate 4222.

[0046] Furthermore, the pressing assembly 21 includes a support plate 211 arranged parallel to the label removal knife 221 and a pressing cylinder 212 with its output end abutting against the support plate 211. The output end of the pressing cylinder 212 is arranged toward the support plate 211 and is used to press the label toward the bottom tape in the direction of the support plate 211.

[0047] On the one hand, it can avoid the situation where the label and the base tape do not separate when passing through the label removal knife 221 due to the gap between the label and the base tape.

[0048] On the other hand, pressing the label tightly against the base tape can flatten the label tape, preventing wrinkles from forming during labeling and affecting the appearance.

[0049] Preferably, the label removal knife 221 is provided with a pair of guide blocks 2211 on the side near the material feeding direction. The guide blocks 2211 are located on both sides of the label tape to control the stability of the label tape direction when it is fed, and to ensure the accuracy of the label position when it is adsorbed onto the adsorption plate 4222.

[0050] Please continue reading. Figure 1 It also includes a feeding roller 5 and a tensioning roller 6 disposed between the feeding roller 5 and the label removal device 2. The feeding roller 5 feeds labels from itself toward the label removal device 2, and the tensioning roller 6 tensions the feeding label strip so that the label strip receives lateral tension when it passes the label removal knife 221, making it easier for the label to detach from the bottom strip.

[0051] Please continue reading. Figure 2It also includes a receiving drive roller group 7 located downstream of the label removal device 2 along the label tape conveying direction. Specifically, the receiving drive roller group 7 includes a guide roller 71, an auxiliary roller 72, and a drive roller 73, which are arranged parallel to each other and rotatably mounted vertically on the worktable 1. The drive roller 73 and the auxiliary roller 72 are in close contact with each other to clamp the bottom tape and drive the bottom tape towards the receiving roller 8 for receiving. The design of the guide roller 71 ensures that the path of the label tape through the label removal knife 221 remains consistent, and the labels adsorbed on the adsorption plate 4222 also remain consistent, avoiding skewing of the labels after application.

[0052] It should be noted that a wire harness labeling machine 1000 also includes a wire harness conveying device 9, which is located on the side of the workbench near the wire frame 3. It is used to transport the wire harness to be labeled and to transport the labeled wire harness away, thereby achieving automatic feeding of the wire harness in conjunction with the wire frame 3.

[0053] The implementation principle of the wire harness labeling machine 1000 in this utility model is as follows: the unloading roller with the label tape roll is installed on the worktable 1, and the label tape is pulled in sequence through the tension roller, the pressing component 21, the label removal knife 221, the adjusting roller 222, and after being wound around the guide roller 71, it enters the drive roller 73 and the auxiliary roller 72. Finally, the receiving roller 8 collects the material, completing the setup before starting the equipment. The technicians then turn on the equipment. After the equipment starts, the label tape is pressed by the clamping assembly 21 and moves towards the label removal knife 221. The label detaches from the base tape at the knife edge and is then adsorbed and removed by the adsorption plate 4222. Subsequently, the moving plate 41 moves backward to a position opposite to the wire frame 3, and the clamping assembly 42 moves towards the wire frame 3, bringing the clamping plate structure 422 closer until the wire harness abuts against the guide strip 4225. The second drive cylinder 4226 drives the first drive cylinder 4223 to move, and the first drive cylinder 4223 drives the connector, causing the adsorption plate 4222 to close, folding and attaching the label adsorbed on the adsorption plate 4222, completing the labeling. Then, the clamping assembly 42 returns to the label removal device 2 along the original path, waiting for the label removal knife 221 to perform the next label removal. After the label removal is completed, the base tape moves towards the take-up roller 8 under the drive of the take-up drive roller group 7, and is finally wound up by the take-up roller 8.

[0054] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
