Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically relating to a film tearing mechanism and a positioning and feeding device. Background Technology

[0002] In current automated operation scenarios, the processing of BMU flexible circuit boards (usually referring to flexible circuit boards related to battery management units, which are characterized by being thin, light, and highly integrated) faces typical challenges in delicate operation.

[0003] From the perspective of the characteristics of BMU flexible printed circuit boards (FPCBs), these components are designed to fit the compact installation space of battery systems, and are generally designed with small volume and thin thickness. The overall size of most products is only a few centimeters, and some precision models are even smaller. The matching positioning fixtures must also strictly adhere to the design principles of small size and high precision to ensure that the FPCB does not shift during processing and meets the accuracy requirements of subsequent processes.

[0004] In the process requirements of BMU flexible printed circuit boards, specific areas of the BMU flexible printed circuit board need to be pre-attached with functional adhesive tape. The release paper covering the surface of this adhesive tape must be completely removed before subsequent assembly. The industrial robots and their corresponding grippers used in existing automated operations face significant space and precision conflicts when adapting to this process. On the one hand, to achieve stable gripping of release paper, the robot gripper needs to have a certain gripping stroke and structural strength. The minimum closed dimension of common micro grippers needs to reach 3-5 mm. However, the available operating space around the BMU flexible circuit board positioning fixture is often less than 10 mm. During the insertion process, the gripper is very likely to collide with the positioning protrusion of the fixture, the edge of the flexible circuit board, or adjacent components. This can lead to failure in gripping the release paper or scratch the circuitry on the surface of the flexible circuit board or damage fragile electronic components. On the other hand, even if the gripper manages to enter the working space, due to space limitations, the robot's movement trajectory cannot achieve the ideal horizontal peeling action. It often needs to be completed by tilting or zigzag motion. This non-standard action can not only easily cause the release paper to break, but may also cause the adhesive tape to fall off the flexible circuit board due to uneven force, which will increase rework costs. Summary of the Invention

[0005] To address the shortcomings of the prior art, this utility model provides a film-tearing mechanism and a positioning and feeding device, which can remove the release paper in a small space and ensure the positioning stability of the product.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a film-tearing mechanism, including a film-tearing auxiliary module and a film-tearing robot, wherein the film-tearing auxiliary module and the film-tearing robot are arranged adjacent to each other; The film-peeling auxiliary module includes a clamp, an upper lifting module, a lower pressing module, and a vacuum module. The clamp is used to load products with adhesive tape attached. The upper lifting module is located below the clamp, and the lower pressing module is located above the clamp. The vacuum module is used to enable the clamp to adsorb the product. The pressing module is used to press down the product and avoid the adhesive tape area, the lifting module is used to lift the release paper exposed at the edge of the adhesive tape upwards, and the film-tearing robot clamps the release paper and tears it off.

[0007] In some implementations, the fixture has a first groove for product positioning, and a first through hole is formed on the first groove at the position of the release paper exposed at the edge of the adhesive tape. The first through hole is used to avoid the upward lifting of the upper module.

[0008] In some implementations, the top module includes a first lifting drive cylinder and a top rod connected to the drive end of the first lifting drive cylinder.

[0009] In some implementations, the pressing module includes a second lifting drive cylinder and a pressing block connected to the drive end of the second lifting drive cylinder; The pressing block is connected to a guide buffer unit.

[0010] In some implementations, the vacuum module includes a first horizontal drive cylinder and a vacuum tube connected to the drive end of the first horizontal drive cylinder.

[0011] In some implementations, the film-tearing robot includes a robotic arm and a gripper unit connected to the drive end of the robotic arm.

[0012] On the other hand, this application also provides a positioning and feeding device, including a feeding mechanism, a pressure holding mechanism, a conveying mechanism and a film tearing mechanism as described in any one of the above. The film-tearing mechanism, the feeding mechanism, and the pressure-holding mechanism are arranged sequentially along the conveying path of the conveying mechanism.

[0013] In some implementations, the feeding mechanism includes a feeding robot and an opening module for opening the clamp.

[0014] In some implementations, a visual inspection mechanism is also included, which is located on the feeding path of the feeding mechanism and is used to inspect the products at the feeding mechanism.

[0015] In some implementations, the pressure-holding mechanism includes a first pressure-holding module and a second pressure-holding module; The first pressure holding module and the second pressure holding module are arranged sequentially along the conveying path of the conveying mechanism.

[0016] In summary, this utility model has at least the following advantages: 1. The present invention provides a film-tearing mechanism that loads the product using a clamp and uses a vacuum module to create an adsorption effect on the product by the clamp, ensuring the stability of the product's positioning. Furthermore, to solve the problem of insufficient space, the upper lifting module first lifts the release paper exposed at the edge of the adhesive tape upwards, and then the film-tearing robot clamps the lifted portion of the release paper and tears it off. This effectively avoids problems such as film breakage or damage to the product edge caused by space limitations of the film-tearing robot. Moreover, during the film-tearing process, the lower pressing module presses down on the product and avoids the adhesive tape area, which further ensures the product's positioning stability and does not interfere with the film-tearing process.

[0017] 2. The positioning and feeding device provided by this utility model, after applying the above-mentioned film-tearing mechanism, can remove the release paper in a small space and ensure the positioning stability of the product. Attached Figure Description

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Example 1: Please see Figure 1 A film-removing mechanism is used to remove the release paper from the surface of the adhesive tape attached to a product, such as a BMU flexible circuit board or a battery cell.

[0024] The film-removing mechanism includes a film-removing auxiliary module 100 and a film-removing robot 200, which are arranged adjacent to each other. The film-removing auxiliary module 100 is mainly used for loading and positioning the product, and the film-removing robot 200 is used to remove the release paper from the surface of the adhesive tape attached to the product.

[0025] The film-peeling auxiliary module 100 includes a clamp 110, an upper top module 120, a lower pressure module 130, and a vacuum module 140. The clamp 110 is used to load the product with the adhesive tape attached. The upper top module 120 is located below the clamp 110, and the lower pressure module 130 is located above the clamp 110. The vacuum module 140 is used to make the clamp 110 adsorb the product.

[0026] For example, if the product is a BMU flexible circuit board, adhesive tape is attached to a portion of the BMU flexible circuit board, and release paper is covered on the adhesive tape, with some of the release paper protruding from the edge of the adhesive tape. The BMU flexible circuit board is loaded onto the fixture 110, and the vacuum module 140 is used to make the fixture 110 adsorb the BMU flexible circuit board, ensuring the positioning stability of the BMU flexible circuit board.

[0027] The upper push module 120 is located below the clamp 110 and is used to move upward to lift the release paper exposed at the edge of the adhesive tape. The lower press module 130 is located above the clamp 110 and is used to move downward to avoid the adhesive tape area and press the product to avoid pressing the adhesive tape and affecting the film peeling operation. The film peeling robot 200 is used to clamp the part of the release paper that is lifted upward and to peel off the release paper.

[0028] During the actual operation, the BMU flexible board is loaded by the clamp 110, and the vacuum module 140 is used to make the clamp 110 adsorb the BMU flexible board, ensuring the positioning stability of the BMU flexible board. In the actual film peeling process, the release paper exposed at the edge of the adhesive tape is first lifted upward by the upper lifting module 120, so that the release paper is in a raised state. Then, the film peeling robot 200 clamps the lifted part of the release paper and peels it off, thereby effectively avoiding problems such as film breakage or damage to the product edge caused by the film peeling robot 200 due to space limitations. In addition, during the film peeling process, the lower pressing module 130 presses down on the product and avoids the adhesive tape area, which further ensures the positioning stability of the product and does not interfere with the film peeling process.

[0029] Example 2: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figure 1 Based on the above, refer to Figures 2-6 .

[0030] In this embodiment, a first groove 111 for product positioning is formed on the clamp 110, and a first through hole 112 is formed on the first groove 111 at the position of the release paper at the edge of the adhesive paper; the first through hole 112 is used to avoid the upward lifting of the top module 120.

[0031] Specifically, the first groove 111 is a contour groove, and the shape of the first groove 111 matches the shape of the product. For example, the BMU flexible board includes the BMU body and the flexible board part. Correspondingly, the first groove 111 includes a recessed part for accommodating and positioning the BMU body and a recessed part for accommodating the flexible board part to ensure the positioning stability of the BMU flexible board.

[0032] It is known that adhesive tape is attached to the BMU flexible board, and release paper is covered on the adhesive tape, with part of the release paper protruding from the edge of the adhesive tape. During the film-tearing operation, the release paper protruding from the edge of the adhesive tape is first lifted upward by the upper lifting module 120. Here, in order to ensure the positioning stability of the BMU flexible board and to enable the upper lifting module 120 to lift upward smoothly, a first through hole 112 is formed on the first groove 111 at the position of the release paper protruding from the edge of the adhesive tape. The first through hole 112 is used to avoid the upward lifting of the upper lifting module 120. That is, during the upward movement of the upper lifting module 120, the release paper is lifted upward through the first through hole 112, so that the release paper is raised, making it easier for the film-tearing robot 200 to clamp and tear it off.

[0033] In some embodiments, the top module 120 includes a first lifting drive cylinder 121 and a top rod 122 connected to the drive end of the first lifting drive cylinder 121.

[0034] During the film-tearing process, the first lifting drive cylinder 121 drives the push rod 122 to lift upward. The push rod 122 first contacts the release paper exposed at the edge of the adhesive paper, and then lifts the release paper upward, so that the release paper is in a raised state, so that the film-tearing robot 200 can clamp and tear it off.

[0035] In some embodiments, the pressing module 130 includes a second lifting drive cylinder 131 and a pressing block 132 connected to the drive end of the second lifting drive cylinder 131; the pressing block 132 is connected to a guide buffer unit 133.

[0036] During the film-removal process, in order to prevent the BMU flexible board from changing position when the film-removal robot 200 clamps and removes the release paper, the BMU flexible board is first pressed down by the pressing module 130, avoiding the adhesive paper area.

[0037] Specifically, the second lifting drive cylinder 131 drives the lower pressure block 132 to move downward. The lower pressure block 132 presses down on the BMU flexible board and avoids the adhesive paper area. This ensures the positional stability of the BMU flexible board during the film-tearing process without interfering with the smooth film-tearing operation.

[0038] Furthermore, the pressing block 132 is connected to a guide buffer unit 133, which can guide the up and down movement of the pressing block 132 and buffer the downward pressure of the pressing block 132.

[0039] For example, the guide buffer unit 133 includes a spring, a guide rail, and a slider along the guide rail slide. The guide rail extends along the driving direction of the second lifting drive cylinder 131. The lower pressure block 132 is connected to the slider. Under the downward driving action of the second lifting drive cylinder 131, the lower pressure block 132 moves downward and slides on the guide rail via the slider, thereby ensuring the positional stability of the downward movement of the lower pressure block 132. The lower end of the spring is connected to the upper end of the lower pressure block 132. After the lower pressure block 132 moves downward to contact the BMU flexible board, under the continued downward driving action of the second lifting drive cylinder 131, the lower pressure block 132 will squeeze the spring upward, thereby preventing the lower pressure block 132 from making hard contact with the BMU flexible board and damaging the BMU flexible board, thus protecting the BMU flexible board.

[0040] In some embodiments, the vacuum module 140 includes a first horizontal drive cylinder 141 and a vacuum pipe 142 connected to the drive end of the first horizontal drive cylinder 141.

[0041] When the fixture 110 moves to the vacuum module 140 position, the first horizontal drive cylinder 141 drives the vacuum tube 142 to move to align with the vacuum hole on the fixture 110, so that the fixture 110 generates a vacuum adsorption effect on the BMU flexible board.

[0042] Understandably, the fixture 110 has several vacuum suction holes at the positions for loading the BMU flexible circuit board. These vacuum suction holes, under the action of the vacuum module 140, create a vacuum suction effect on the BMU flexible circuit board. After the film-tearing operation is completed, the first horizontal drive cylinder 141 drives the vacuum tube 142 to reset, causing the fixture 110 to break the vacuum and continue to move to the next work station.

[0043] In some embodiments, the film-tearing robot 200 includes a manipulator 210 and a gripper unit 220 connected to the drive end of the manipulator 210.

[0044] Under the drive of the robot arm 210, the gripper unit 220 moves to a set position, such as to the position of the corresponding raised release paper, and places the raised release paper in the middle of the gripper unit 220.

[0045] Specifically, the gripper unit 220 includes a first gripper and a second gripper arranged opposite to each other. Before moving to the release paper position, the first gripper and the second gripper are in an open state. Under the driving action of the robot, the raised release paper is positioned between the first gripper and the second gripper. Then, the first gripper and the second gripper clamp the release paper and tear it off under the action of the robot 210.

[0046] The film-tearing mechanism provided in this embodiment can remove the release paper in a small space and ensure the positioning stability of the product.

[0047] Example 3: This embodiment provides a positioning and feeding device based on embodiment 1 or 2. Please refer to... Figures 1-6 Based on the above, refer to Figure 7 and Figure 8 .

[0048] A positioning and feeding device includes a feeding mechanism 300, a pressure holding mechanism 400, a conveying mechanism 500, and a film tearing mechanism as described in Embodiment 1 or Embodiment 2 above. The film tearing mechanism, the feeding mechanism 300, and the pressure holding mechanism 400 are arranged sequentially along the conveying path of the conveying mechanism 500.

[0049] In this embodiment, the film-peeling mechanism is used to peel the film off the BMU flexible circuit board with adhesive tape attached. The feeding mechanism 300 is used to feed the BUSBAR onto the adhesive tape of the BMU flexible circuit board, wherein the BUSBAR is a bus. The pressure-holding mechanism 400 is used to hold the BUSBAR under pressure, and the conveying mechanism 500 is used to transport the clamp 110 carrying the BMU flexible circuit board, so that the BMU flexible circuit board moves to the corresponding mechanism for the corresponding operation.

[0050] In the specific operation process, the release paper is first torn off by the film tearing mechanism. Then, under the transmission action of the conveying mechanism 500, the clamp 110 is conveyed to the corresponding feeding mechanism 300. The feeding mechanism 300 feeds the BUSBAR to the adhesive paper of the BMU flexible board. Then, the clamp 110 continues to be conveyed to the corresponding pressure holding mechanism 400 under the transmission action of the conveying mechanism 500. The pressure holding mechanism 400 holds the BUSBAR under pressure.

[0051] In some embodiments, the feeding mechanism 300 includes a feeding robot 310 and an opening module 320 for opening the clamp 110.

[0052] The loading robot 310 is used to transport the BUSBAR from the blister pack and load it onto the adhesive tape of the BMU flexible board. The clamping module 320 is used to open the clamp 110. Understandably, before the loading robot 310 loads the BUSBAR onto the adhesive tape of the BMU flexible board, the clamping module 320 first makes the clamp 110 appear in an open state. After the loading robot 310 loads the BUSBAR onto the adhesive tape of the BMU flexible board, the clamping module 320 resets, and the clamp 110 appears in a closed state to ensure the positioning stability of the BMU flexible board.

[0053] In some embodiments, the positioning and feeding device further includes a vision inspection mechanism 600, which is located on the feeding path of the feeding mechanism 300 and is used to inspect the product at the feeding mechanism 300. For example, in the required scenario, it can be used to detect the position information of the BUSBAR to correct the feeding position of the BUSBAR, or to detect whether the BUSBAR has defects. Of course, it can also detect both the position information of the BUSBAR and whether the BUSBAR has defects.

[0054] In some embodiments, the pressure holding mechanism 400 includes a first pressure holding module 410 and a second pressure holding module 420; the first pressure holding module 410 and the second pressure holding module 420 are arranged sequentially along the conveying path of the conveying mechanism 500.

[0055] Under the action of the conveying mechanism 500, the clamp 110 is first conveyed to the first pressure holding module 410 for pressure holding, and then conveyed to the second pressure holding module 420 for protection. Under the action of the two pressure holding actions, the connection stability between the BUSBAR and the BMU flexible board can be ensured.

[0056] The positioning and feeding device provided in this embodiment, after applying the above-mentioned film-tearing mechanism, can remove the release paper in a small space and ensure the positioning stability of the product.

[0057] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
