Description

Technical Field

[0001] This utility model relates to the field of membrane material processing technology, and specifically to a membrane material positioning and transfer structure. Background Technology

[0002] The separator is a key material in lithium-ion battery manufacturing. It is usually made of polyethylene or polypropylene and has a microporous structure. It is mainly used to separate the positive and negative electrode materials and allow lithium ions to pass through freely. During the production of the separator, the first and last parts need to be inspected. Specifically, the separator is placed on a positioning structure for positioning, and then cut in the middle of the separator by a cutting device to make the cut separator into a sample. The sample is then sent to the downstream equipment for relevant tests.

[0003] Currently, the utility model patent with announcement number CN220162611U discloses a hot stamping stencil cutting and positioning assembly, including an operating frame, a smoothing mechanism, a cutting mechanism, and a support mechanism. The smoothing mechanism is located at the top of the support mechanism, the cutting mechanism is located at the top of the operating frame, and the support mechanism is located at the inner end of the operating frame. The smoothing mechanism includes a connecting rod, an elastic element, and a smoothing positioning plate. The elastic element is fixedly installed at the bottom end of the connecting rod, and the smoothing positioning plate is fixedly installed at the bottom end of the elastic element and fits against the support mechanism. It can smooth the hot stamping stencil that needs to be cut, and after smoothing, it can be pressed to position the hot stamping stencil, facilitating subsequent cutting work.

[0004] In existing technologies, membrane materials are mostly positioned by pressing during cutting, allowing them to lie flat on the cutting table for easy cutting. However, the pressing method relies on friction during the smoothing process, which is unsuitable for ultra-thin, smooth membrane materials, such as battery cell rolls, which are prone to displacement and require secondary adjustments, affecting cutting efficiency. To address this issue, this application provides a membrane material positioning and transfer structure. Utility Model Content

[0005] Based on the above description, this utility model provides a membrane material positioning and transplanting structure to solve the problem that the existing pressing and positioning structure for positioning membrane materials is difficult to adapt to ultra-thin and smooth membrane materials and is prone to displacement.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a membrane material positioning and transplanting structure, including a frame, a steel plate and an inner plate are provided inside the frame, the inner plate is located below the steel plate, and a support module for placing the diaphragm is provided on the top of the steel plate; It also includes a positioning mechanism and a linear module, wherein the linear module is located on the inner plate and is equipped with a lifting module capable of vertical lifting and lowering. The positioning mechanism includes a sample positioning module mounted on the lifting module and a peripheral positioning module mounted on the support module. The sample positioning module moves vertically via the lifting module. The lifting module is also equipped with an integrated vacuum module. Both the sample positioning module and the peripheral positioning module are equipped with several gas guides. The sample positioning module and the peripheral positioning module are connected to the integrated vacuum module through the gas guides and are internally interconnected.

[0007] Through the above technical solution, the linear module can drive the lifting module and its connected components to move linearly, thereby realizing the transplantation function; the lifting module can drive the positioning mechanism to move out of the support module or move inside it; the positioning mechanism can divide the diaphragm into sections for positioning, so that the sample area to be cut can be separated from the surrounding area, and can also be moved relative to it after cutting.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the support module includes a support shell mounted on a steel plate, with openings at the top, bottom, and right side. A support plate is provided at the top of the support shell, and an anti-static mat is placed on the support plate.

[0010] The above technical solution enables the support plate to accommodate the diaphragm, and the opening at the bottom of the support shell to allow the positioning mechanism to move.

[0011] Furthermore, the lifting module includes two sliders mounted on the linear module. The sliders are driven by the linear module to move left and right in a linear motion, and a sliding plate is provided between the tops of the two sliders. The sliding plate is equipped with two DC electric push rods, and a lifting plate is provided between the piston ends of the two DC electric push rods.

[0012] The above technical solution enables the linear module to drive the slider, thereby driving the sliding plate to move in a linear motion; the DC electric push rod can drive the lifting plate to move up and down.

[0013] Furthermore, the integrated vacuum module is located on the top of the sliding plate, and the integrated vacuum module is composed of several vacuum pumps.

[0014] The above technical solution enables the integrated vacuum module to provide air extraction, thereby allowing the membrane to be adsorbed and positioned through vacuum extraction.

[0015] Furthermore, the sample positioning module includes several negative pressure shells on the lifting plate. The negative pressure shells are arranged at equal distances along a straight line from left to right. A fixed cover is detachably connected to the negative pressure shell. A rubber pad is glued to the fixed cover. Both the fixed cover and the rubber pad are circular and have the same area. Several ventilation holes are opened between the top of the fixed cover and the rubber pad. The bottom of the negative pressure shell is detachably connected to a threaded cylinder and a quick connector, the interior of which is connected to the interior of the negative pressure shell.

[0016] Through the above technical solution, the negative pressure shell and the fixed cover can form a relatively sealed space, and the rubber pad can play a non-slip role.

[0017] Furthermore, a connecting hole is provided between the top of the fixed cover and the rubber pad, through which the piston end of the threaded cylinder passes, and the piston end of the threaded cylinder is located at the center of the fixed cover and the rubber pad.

[0018] Through the above technical solution, the piston end of the threaded cylinder can push the cut diaphragm sample upward through the connecting hole.

[0019] Furthermore, the peripheral positioning module includes several outer boxes embedded in the top of the support plate, and the anti-static mat has outer holes for inserting the outer boxes. The bottom of the outer boxes is provided with quick connectors, and the top of the outer boxes has evenly distributed round holes. The outer boxes are symmetrically distributed with the negative pressure shells arranged in a straight line as the center line.

[0020] The above technical solution enables the outer box to cover the bottom of the outer ring of the diaphragm.

[0021] Furthermore, the bottom of the support plate is provided with a mounting hole for the quick connector to pass through, and the interior of the quick connector and the circular hole are connected to the interior of the corresponding outer box.

[0022] The above technical solution enables airflow to circulate within the round hole, the outer box, and the quick connector.

[0023] Furthermore, the steel plate is provided with a lifting port that communicates with the interior of the support shell, and the lifting port and the interior of the support shell allow the lifting plate to move up and down. A connection hole is provided between the support plate and the top of the antistatic mat for the fixing cover to pass through.

[0024] The above technical solution allows the lifting plate to move between the lifting port and the interior of the support shell, and allows the fixed cover to move to the top of the support shell through the connecting hole.

[0025] Furthermore, the air guide includes a spring air tube, and the bottom ends of the threaded cylinder, quick connector, and fast coupling are all provided with spring air tubes, with the bottom end of the spring air tube adjacent to the integrated vacuum module.

[0026] The above technical solution enables the integrated vacuum module to perform air extraction through the spring tube, and then use negative pressure to adsorb and position the diaphragm.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. By using a partitioned adsorption positioning method, the outer and inner surfaces to be cut can be distinguished, so that the diaphragm can be stably and effectively positioned before, during and after cutting, and is less likely to shift or deviate, allowing it to be transported in a predetermined posture. 2. The support module can support the entire diaphragm and greatly reduce the impact of electrostatic adsorption on positioning, allowing it to be placed flat; the linear module can transport the cut diaphragm sample, thereby completing the transfer of the diaphragm sample.

[0030] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0031] 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 application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0032] Example: Reference Figure 1 and Figure 2 A membrane material positioning and transfer structure includes a frame 1, with a steel plate 2 and an inner plate 4 inside the frame 1. The inner plate 4 is located below the steel plate 2, and a support module 3 for placing a diaphragm is provided on the top of the steel plate 2. It also includes a positioning mechanism 7 and a linear module 5. The linear module 5 is located on the inner plate 4 and has a lifting module capable of vertical lifting and lowering. The positioning mechanism 7 includes a sample positioning module on the lifting module and a peripheral positioning module on the support module 3. The sample positioning module moves vertically through the lifting module. The lifting module also has an integrated vacuum module 71. Both the sample positioning module and the peripheral positioning module have several air guides. The sample positioning module and the peripheral positioning module are connected to the integrated vacuum module 71 through the air guides and are internally interconnected.

[0033] It should be noted that the frame 1 is also equipped with a cutting mechanism for cutting the diaphragm. The diaphragm is cut by the cooperation of a robot and a cutting tool. The robot drives the cutting tool to move along a specified path and then cuts the diaphragm. Both the robot and the cutting tool are commonly used equipment in existing industrial technology, so they will not be described in detail. The cutting point is located outside the sample positioning module, so that the cut sample can be positioned by the sample positioning module.

[0034] refer to Figure 2 and Figure 3The support module 3 includes a support shell 31 mounted on a steel plate 2. The top, bottom, and right side of the support shell 31 are all open. The top of the support shell 31 is provided with a support plate 32, which allows the diaphragm to be placed. The opening at the bottom of the support shell 31 also allows the positioning mechanism 7 to move. An antistatic mat 33 is placed on the support plate 32. The antistatic mat 33 reduces the electrostatic adsorption force between the diaphragm and the contact parts during placement, allowing it to be placed smoothly and stably.

[0035] refer to Figure 4 and Figure 6 The lifting module includes two sliders 61 mounted on the linear module 5. The sliders 61 are driven by the linear module 5 to move left and right in a straight line. A sliding plate 62 is provided between the tops of the two sliders 61, so that the linear module 5 can drive the sliders 61 to drive the sliding plate 62 to move in a straight line. Two DC electric push rods 63 are provided on the sliding plate 62. A lifting plate 64 is provided between the piston ends of the two DC electric push rods 63. The DC electric push rods 63 can drive the lifting plate 64 to move up and down.

[0036] It should be noted that the two DC electric actuators 63 are controlled by the same control element, which makes it easy to achieve simultaneous upward or downward movement.

[0037] It should also be noted that the linear module 5 consists of a servo motor, a linear screw, and two guide rails. The slider 61 is slidably connected between the outer sides of the two guide rails and threadedly connected to the outer side of the linear screw. By limiting and guiding the guide rails, and by driving the linear screw to rotate through the servo motor, the two sliders 61 and their connected structure can be driven to achieve the effect of linear movement. This is a commonly used linear device in the prior art, so it will not be described in detail.

[0038] refer to Figure 6 An integrated vacuum module 71 is located on top of the sliding plate 62. The integrated vacuum module 71 is composed of several vacuum pumps, which enables the integrated vacuum module 71 to provide the function of evacuation, thereby enabling the membrane to be adsorbed and positioned by evacuation.

[0039] refer to Figure 2 , Figure 5 and Figure 8 The sample positioning module includes several negative pressure shells 72 on the lifting plate 64. The negative pressure shells 72 are arranged at equal distances along a straight line from left to right. A fixed cover 73 is detachably connected to the negative pressure shell 72. A rubber pad 74 is glued to the fixed cover 73. The negative pressure shell 72 and the fixed cover 73 can form a relatively sealed space. The rubber pad 74 can play a non-slip role.

[0040] refer to Figure 8 and Figure 9The fixed cover 73 and the rubber pad 74 are both circular and have the same area. Several vent holes 75 are opened between the top of the fixed cover 73 and the rubber pad 74 to allow airflow to pass through normally. The bottom of the negative pressure shell 72 is detachably connected to a threaded cylinder 76 and a quick connector 77. The interior of the quick connector 77 is connected to the interior of the negative pressure shell 72. Air can be drawn from the interior of the negative pressure shell 72 through the quick connector 77 to form a negative pressure space inside. The diaphragm placed on the top can then be adsorbed and positioned through the vent holes 75.

[0041] refer to Figure 9 A connecting hole is provided between the top of the fixed cover 73 and the rubber pad 74. The connecting hole allows the piston end of the threaded cylinder 76 to pass through. The piston end of the threaded cylinder 76 is located at the center of the fixed cover 73 and the rubber pad 74. The piston end of the threaded cylinder 76 can lift the cut diaphragm sample upward through the connecting hole, making it convenient for the cut diaphragm sample to be picked up by a robot or manually.

[0042] refer to Figure 3 and Figure 7 The peripheral positioning module includes several outer boxes 78 embedded in the top of the support plate 32. The antistatic mat 33 has outer holes for the outer boxes 78 to be inserted, so that the outer boxes 78 can adsorb and position the diaphragm placed on the antistatic mat. The bottom of the outer box 78 is provided with a quick connector 79, and the top of the outer box 78 has evenly distributed round holes 710. The outer boxes 78 are symmetrically distributed with the straight line formed by the negative pressure shells 72 as the center line, so that the outer boxes 78 can cover the bottom of the outer ring of the diaphragm.

[0043] refer to Figure 3 and Figure 7 The bottom of the support plate 32 has an installation hole for the quick connector 79 to pass through. The interior of the quick connector 79 and the round hole 710 are connected to the interior of the corresponding outer box 78, so that airflow can circulate inside the round hole 710, the outer box 78 and the quick connector 79.

[0044] refer to Figure 2 , Figure 4 and Figure 5 The steel plate 2 has a lifting port that communicates with the inside of the support shell 31. The lifting port and the inside of the support shell 31 allow the lifting plate 64 to move up and down. The top of the support plate 32 and the antistatic mat 33 have a connecting hole through which the fixing cover 73 passes, allowing the lifting plate 64 to move between the lifting port and the inside of the support shell 31, and allowing the fixing cover 73 to move to the top of the support shell 31 through the connecting hole.

[0045] refer to Figure 4The air guide includes a spring air tube. The bottom ends of the threaded cylinder 76, quick connector 77 and quick connector 79 are all equipped with spring air tubes. The bottom ends of the spring air tubes are adjacent to the integrated vacuum module 71, so that the integrated vacuum module 71 can perform the action of evacuating air through the spring air tubes, and then use negative pressure to adsorb and position the diaphragm.

[0046] It should be noted that the spring air tube can be stretched or shortened when the positioning mechanism 7 is driven by the linear module 5 to move linearly, which facilitates wiring and use.

[0047] In use, the diaphragm is placed on the support plate 32, and the integrated vacuum module 71 is activated. Through the connection of the spring air tube, a negative pressure space is formed in both the negative pressure shell 72 and the outer box 78, which can adsorb and position the diaphragm placed between them. Then, the sample part in the diaphragm is cut so that the diaphragm can be cut into several circular samples, and these circular samples can be positioned by the negative pressure in the negative pressure shell 72. The DC electric push rod 63 drives the lifting plate 64 to descend, so that the lifting plate 64 can move to the bottom of the support shell 31. Then, the linear module 5 drives the slider 61 to move, which can transfer the positioned circular samples. When it is necessary to remove them, the vacuum of the integrated vacuum module 71 corresponding to the negative pressure shell 72 is released, so that the circular samples are no longer positioned. The threaded cylinder 76 is activated to lift the circular samples upwards for easy removal for subsequent testing.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
