Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, specifically relating to a mechanism for removing Mylar film to prevent sticking. Background Technology

[0002] The inherent electrostatic properties of Mylar membranes make them prone to attracting dust and other fine particles. Furthermore, multiple Mylar membranes are typically stacked, and this electrostatic interaction can cause unintended adhesion between the membranes. When operators attempt to separate individual Mylar membranes from the stack for subsequent processes, they often end up removing two or more at once. This severely impacts production line efficiency and accuracy. Moreover, excess Mylar membranes, if not properly controlled, can easily fall during transport. This not only wastes materials and increases production costs but, more importantly, can disrupt normal equipment operation.

[0003] To avoid the aforementioned problems, a Mylar film anti-sticking mechanism is typically used to remove individual Mylar films. Existing Mylar film anti-sticking mechanisms usually include a suction component, a brush component, and a shaking component. During operation, the suction component first picks up the Mylar film. After suction, the brush inside the brush component spreads out multiple Mylar films and blows air into the center of each film. Then, the shaking component drives the suction component to shake repeatedly, thus shaking off any excess Mylar film adhering to the bottom. It can be seen that the shaking component affects the entire Mylar film. Under the influence of shaking and static electricity, large areas of the Mylar film are easily wrinkled and bent, resulting in an uneven removal of the individual Mylar film and the Mylar film falling onto the worktable. Furthermore, the brush component accumulates a lot of dirt after prolonged use, which can damage subsequent Mylar films. Therefore, the practicality of existing Mylar film anti-sticking mechanisms is relatively low. Utility Model Content

Each of the fixation flexible suction cups and the vacuum unit are disposed on the frame, and the vacuum unit is in communication with each of the fixation flexible suction cups. The driving assembly and the bending adsorption assembly are connected to the frame.

[0013] In some embodiments, the bending adsorption assembly includes a plate and a plurality of bending flexible suction cups, the plate being rotatably connected to the fixed adsorption assembly, and each of the bending flexible suction cups being uniformly disposed on the plate.

[0014] In some embodiments, a vacuum detection component for detecting the vacuum suction value during adsorption is also included, the vacuum detection unit being connected to the frame.

[0015] In some embodiments, the method further includes a positioning detection component for detecting arrival at the Mylar membrane site, the positioning detection component being connected to the fixation adsorption component.

[0019] In summary, this utility model has at least the following advantages:

[0020] The Mylar film anti-sticking mechanism provided by this utility model positions one end of the Mylar film using a fixed adsorption component, while a driving component drives a bending adsorption component to bend the other end of the Mylar film. This achieves a good separation effect. Because it only bends the other end of the Mylar film, it effectively avoids large-area wrinkling and unevenness in the removed Mylar film, resulting in a smoother removed sheet and a more even surface. Furthermore, it eliminates the need for additional separation structures, simplifying the structure and effectively preventing unnecessary parts from contaminating the Mylar film after prolonged use. Therefore, the Mylar film anti-sticking mechanism of this application is more practical. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] In the following embodiments and accompanying drawings, reference is made to Figure 1 The coordinate system is defined with the direction indicated by the arrow on the X-axis as right, the direction indicated by the arrow on the Y-axis as forward, and the direction indicated by the arrow on the Z-axis as up. The horizontal plane is set as the plane formed by the X-axis and Y-axis.

[0039] During operation, the robotic arm or other drive mechanisms drive the Mylar film anti-adhesion mechanism 10 to run, and its operation proceeds from bottom to top, passing through the Mylar film picking position, the bending position, and the safety position. Specifically, at the Mylar film picking position, the flat Mylar film is adsorbed and picked up; at the bending adsorption component 200, it bends at the bending position; and when the Mylar film anti-adhesion mechanism 10 reaches the safety position, the process of picking up a single Mylar film is completed.

[0040] Example 1:

[0041] like Figure 1 and Figure 2As shown, in this embodiment, a Mylar film anti-adhesion mechanism 10 is provided, comprising: a fixed adsorption component 100 for horizontally positioning and adsorbing one end of the Mylar film; a bending adsorption component 200, which is rotatably connected to the fixed adsorption component 100 and is used to rotate after horizontally adsorbing the other end of the Mylar film so that excess Mylar film falls off during bending; and a driving component 300, which is connected to the fixed adsorption component 100 and whose output end is connected to the bending adsorption component 200 for driving the bending adsorption component 200 to rotate relative to the fixed adsorption component 100.

[0042] Specifically, the fixed adsorption assembly 100 is used for vacuum adsorption of the left end of the Mylar membrane. The fixed adsorption assembly 100 is positioned and mounted on a robotic arm or other driving mechanism, ensuring that the fixed adsorption assembly 100 is horizontally positioned. The robotic arm can drive the Mylar membrane anti-adhesion mechanism 10 to the Mylar membrane removal position. The curved adsorption assembly 200 is used for vacuum adsorption of the right end of the Mylar membrane. The curved adsorption assembly 200 is rotatably connected to the fixed adsorption assembly 100. The curved adsorption assembly 200 is normally horizontally positioned and at the same horizontal plane as the fixed adsorption assembly 100. When the Mylar membrane needs to be separated at the curved position, it rotates by a certain angle. The driving assembly 300 is mounted on the fixed adsorption assembly 100.

[0043] It is worth noting that the robotic arm drives the Mylar film anti-adhesion mechanism 10 to descend to the Mylar film retrieval position. Once in position, the fixed adsorption component 100 and the bending adsorption component 200, which are on the same horizontal plane, adsorb both ends of the Mylar film. After the robotic arm rises to the bending position, the drive component 300 works, driving the bending adsorption component 200 to bend the other end of the Mylar film at an angle of about 15° and then return to its original position. After bending twice, the excess Mylar film will fall onto the work platform, thus completing the separation of multiple Mylar films. After the separation is completed, the Mylar film anti-adhesion mechanism 10 rises to the safety position, thus completing the process of retrieving a single Mylar film. In this design, the fixed adsorption component 100 positions one end of the Mylar membrane, while the driving component 300 drives the bending adsorption component 200 to bend the other end of the Mylar membrane. This achieves a good separation effect. Because it only bends the other end of the Mylar membrane, it effectively avoids large-area wrinkling and unevenness in the removed Mylar membrane, resulting in a smoother removed and fallen Mylar membrane. Furthermore, no additional separation structure is required to achieve Mylar membrane separation, simplifying the structure and effectively preventing unnecessary components from contaminating the Mylar membrane after prolonged use. Therefore, the Mylar membrane anti-sticking mechanism 10 of this application is more practical.

[0044] Example 2

[0045] This embodiment is a further implementation of Embodiment 1, such as... Figures 1 to 3 As shown, in this embodiment, the drive assembly 300 includes a driver 310 and a floating connector 320. The output end of the driver 310 is connected to the floating connector 320, and the floating connector 320 is connected to the bending adsorption assembly 200.

[0046] Specifically, the actuator 310 is mounted on the fixed adsorption assembly 100 via the mounting base 330, and the actuator 310 can be, but is not limited to, a cylinder. After the Mylar film anti-adhesion mechanism 10 reaches the bending position, the reciprocating motion of the cylinder extending and retracting drives the bending adsorption assembly 200 to rotate, thereby bending the Mylar film and enabling it to better complete the bending action, separating the adhered double or multiple Mylar films. The method of using a cylinder to drive the floating joint 320 to rotate the bending adsorption assembly 200 is known to those skilled in the art and is feasible, and will not be described in detail in this embodiment.

[0047] It is understandable that the drive component 300 can also be configured with other structures, which are not limited here, as long as it can drive the bending adsorption component 200 to rotate relative to the fixed adsorption component 100.

[0048] To facilitate the use of the fixation adsorption component 100, such as Figures 1 to 4 As shown, in some embodiments, the fixed adsorption assembly 100 includes a frame 110, a vacuum unit 120 and a plurality of fixed flexible suction cups 130. Each fixed flexible suction cup 130 and the vacuum unit 120 are disposed on the frame 110, and the vacuum unit 120 is connected to each fixed flexible suction cup 130. The driving assembly 300 and the bending adsorption assembly 200 are connected to the frame 110.

[0049] Specifically, a vacuum unit 120 is installed on the frame 110. The vacuum unit 120 is used to generate negative pressure on multiple fixed flexible suction cups 130. The method by which the vacuum unit 120 generates negative pressure on the multiple suction cups is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment. The fixed flexible suction cups 130 are made of flexible material to avoid damaging the Mylar film. The multiple fixed flexible suction cups 130 are evenly distributed on the frame 110, and their position distribution is more reasonable. The Mylar film can be picked up without relying on the positioning accuracy of the robot arm. The adsorption surfaces of each fixed flexible suction cup 130 are on the same horizontal plane to horizontally adsorb the left end of the Mylar film, so that the adsorbed Mylar film remains in a straight state. The cylinder is mounted on the frame 110 through the mounting base 330. In this way, after the Mylar film anti-adhesion mechanism 10 descends to the Mylar film picking position and opens the vacuum, the distributed fixed flexible suction cups 130 can obtain a vacuum through air pipes, thereby picking up the Mylar film.

[0050] To facilitate the use of the bending adsorption component 200, such as Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the bending adsorption assembly 200 includes a plate 210 and a plurality of bending flexible suction cups 220. The plate 210 is rotatably connected to the fixed adsorption assembly 100, and each bending flexible suction cup 220 is evenly disposed on the plate 210.

[0051] Specifically, multiple curved flexible suction cups 220 are evenly distributed on the plate 210. Each curved flexible suction cup 220 can be connected to the vacuum unit 120 of the fixed adsorption assembly 100 to generate negative pressure. The adsorption surfaces of each curved flexible suction cup 220 are on the same horizontal plane to horizontally adsorb the right end of the Mylar membrane. The plate 210 is rotatably connected to the frame 110. The cylinder and the floating joint 320 are horizontally arranged along the X-axis. The floating joint 320 is connected to the plate 210 through the L-shaped plate 210 so that the plate 210 can be rotated when driven by the cylinder.

[0052] To facilitate the rotational connection between the bending adsorption component 200 and the stationary adsorption component 100, such as Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, a rotating member 400 is connected between the bending adsorption component 200 and the stationary adsorption component 100.

[0053] Specifically, the rotating component 400 may be, but is not limited to, a hinge. The left end of the hinge is connected to the frame 110 and the right end is connected to the plate 210, so that the bending adsorption component 200 and the fixed adsorption component 100 can be rotatably connected. The bending angle can be freely selected through the hinge, so as to better separate the multilayer Mylar membrane.

[0054] Example 3

[0055] This embodiment is a further implementation of embodiment 1 or 2, such as... Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, the Mylar film anti-adhesion mechanism 10 further includes a positioning detection component 500 for detecting the arrival of the Mylar film at the positioning position, and the positioning detection component 500 is connected to the fixation adsorption component 100.

[0056] Specifically, the arrival detection component 500 is mounted on the frame 110 via a connecting plate. The Mylar film anti-adhesion mechanism 10 descends to the Mylar film pick-up position. Only after the arrival detection component 500 detects normal operation does the vacuum system open, allowing the suction cups to adsorb the Mylar film. By incorporating the arrival detection component 500, precise material handling is achieved.

[0057] To facilitate the use of the positioning detection component 500, such as Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, the positioning detection component 500 includes a base 510, a sensor 520 for transmitting a signal indicating arrival at the Mylar film position, an elastic element 530, and a vertical rod 540. The base 510 is connected to the fixation adsorption component 100. The base 510 has a sliding hole. The sensor 520 is disposed on one end of the base 510, and the elastic element 530 is disposed on the other end of the base 510. One end of the vertical rod 540 is disposed on one side of the sensor 520, and the other end passes through the sliding hole and is connected to the elastic element 530. When subjected to a supporting force, the vertical rod 540 approaches and triggers the sensor 520.

[0058] Specifically, the base 510 is mounted on the frame 110 via a connecting plate, and the base 510 is L-shaped with a sliding hole at its bottom end. The sensor 520 is mounted on the top end of the base 510. The elastic element 530 can be, but is not limited to, a spring; the top end of the elastic element 530 is mounted on the bottom end of the base 510 and corresponds to the sliding hole. The upright 540 is made of chrome-plated rod with surface heat treatment to ensure the durability of the overall mechanism. The top end of the upright 540 is located below the sensor 520, and the bottom end passes through the sliding hole and the elastic element 530, and is fixedly connected to the elastic element 530 on its periphery. Under normal conditions, the upright 540 is held at a certain height by the tension of the elastic element 530, and moves upward to trigger the sensor 520 when subjected to a supporting force. In this way, during the process of the Mylar film anti-adhesion mechanism 10 descending to the Mylar film position, the upright 540 will first contact the bottom surface of the Mylar film. At this time, the upright 540 will be moved upward by the supporting force until its top touches the sensor 520 above. The sensor 520 can feed back the positioning signal, thereby completing the descent action.

[0059] To facilitate the sliding of the upright 540, such as Figure 6 As shown, in some embodiments, a guide 550 is provided between the upright 540 and the sliding hole.

[0060] Specifically, the guide member 550 may be, but is not limited to, a linear bearing. By providing a linear bearing between the upright 540 and the sliding hole, the sliding direction of the upright 540 in the sliding hole is guided, thereby preventing the upright 540 from shifting position during the lifting and lowering process.

[0061] To avoid damaging the Mylar membrane, such as Figure 6 As shown, in some embodiments, the other end of the upright 540 is provided with an abutment portion 541, and a soft layer is provided on the abutment portion 541.

[0062] Specifically, the bottom end of the upright 540 is provided with an abutment portion 541 for contacting the Mylar membrane. The abutment portion 541 can be, but is not limited to, a column, and its cross-sectional area is larger than that of the upright 540. By providing the abutment portion 541, the contact area between the upright 540 and the Mylar membrane is larger, the force is more evenly distributed, and the upright 540 is prevented from shifting due to a small contact area during sliding, thus making the sliding trend of the upright 540 more stable. The bottom of the abutment portion 541 is treated with an adhesive coating process, that is, the soft layer is set as an adhesive layer, which can avoid damage to the Mylar membrane caused by hard contact.

[0063] To increase practicality, such as Figure 1 , Figure 4 and Figure 7 As shown, in some embodiments, the Mylar film anti-adhesion mechanism 10 further includes a vacuum detection component 600 for detecting the vacuum suction value during adsorption, and the vacuum detection unit is connected to the frame 110.

[0064] Specifically, the vacuum detection component 600 is mounted on the frame 110. After the Mylar film anti-adhesion mechanism 10 reaches the Mylar film picking position, a negative pressure vacuum is activated, and the vacuum detection component 600 detects the vacuum absorption value. Once the vacuum absorption value is reached, a signal indicating that the absorption is complete is fed back. The vacuum detection component 600 includes a vacuum gauge 610. The method by which the vacuum gauge 610 detects the vacuum absorption value of the Mylar film anti-adhesion mechanism 10 is known to those skilled in the art and is feasible; therefore, it will not be described in detail in this embodiment.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0067] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
