Description

Technical Field

[0001] This utility model relates to the field of membrane insertion clamps, specifically to a membrane insertion clamp for composite current collectors. Background Technology

[0002] Composite current collectors are functional thin films made of multiple layers of materials. They typically adopt a "metal-polymer material-metal" structure, with polymer material as the middle layer and metal layers (such as copper or aluminum) plated on both sides. They are mainly used to replace traditional metal foils (such as copper foil or aluminum foil) as positive and negative electrode current collectors.

[0003] To achieve continuous production, the manufacturing process of composite current collectors often requires a roll-to-roll production process. In roll-to-roll production, the film material must first be threaded through the roller system, and it must be ensured that it remains flat during subsequent film feeding to prevent wrinkles.

[0004] In the production process of composite current collectors (including magnetron sputtering, vapor deposition, and electroplating), the original film (PET / PP polymer substrate) is prone to breakage during threading due to its low tensile strength (elongation at break >10%, mechanical strength >220MPa) and uneven tension, leading to wrinkles. To avoid uneven winding, existing technologies require an additional ≥20m of original film for adjustment. For example, the conventional threading operation involves manually breaking and gathering the film at the unwinding end into a ball for threading, followed by continuous unwinding until the film surface is flat. This approach causes the following problems: material waste and low efficiency. Due to the limited operating space of some machines, threading must be performed in a small environment, resulting in uneven stress on the film material and easy breakage, affecting threading efficiency. This problem of resource waste and low efficiency exists in sputtering machines, vapor deposition machines, and electroplating machines. Existing film clamping devices cannot achieve stable clamping without demolding without damaging the mold material.

[0005] Therefore, it is necessary to invent a membrane-penetrating clamp for composite current collectors to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a film-threading clamp for composite current collectors. The clamping device holds the end of the mold material using a first clamping plate and a second clamping plate. By holding the first and second clamping plates, the device is driven to shuttle between rollers, which improves the efficiency of film threading. Furthermore, this device only clamps the end of the film material, reducing material waste. During clamping, the device can compress the film material, increasing friction, and with multiple fixation methods such as adsorption, it prevents film detachment. The flexible material design prevents film damage, achieving improved efficiency, reduced waste, and stable clamping, thus solving the problems of material waste and low efficiency in existing technologies.

[0012] The flexible clamp is used to contact the composite current collector; the fixed plate and the flexible clamp are provided with holes that communicate with the adsorption tank. When the first clamp and the second clamp are close to each other, the insertion rod can contact the pressure plate and squeeze the pressure plate to push the adsorption plate to move relative to the fixed plate in the adsorption tank, so as to generate negative pressure in the adsorption tank to adsorb the composite current collector.

[0013] Preferably, handles are fixedly connected to the sides of both the first and second clamping plates, and limit rods are fixedly connected to the four inner corners of the second clamping plate. The limit rods are slidably connected to the first clamping plate, and slots are provided at the four corners of the first clamping plate. The slots cooperate with the limit rods, and a stop block is fixedly connected to the end of the limit rod that passes through the slot.

[0014] Preferably, both the first clamping plate and the second clamping plate have cavities inside, and slots are formed on the outer side of the cavities. The C-shaped plate cooperates with the cavities and is slidably connected to the slots. A first telescopic rod is installed on the inner side of both the first clamping plate and the second clamping plate. The first telescopic rod is fixedly connected to the inner side of the adsorption plate, and a first return spring is sleeved on the outer side of the first telescopic rod.

[0015] Preferably, a second telescopic rod is connected between the inner side of the fixing plate and the adsorption plate, and a second return spring is sleeved on the outer side of the second telescopic rod. Multiple second telescopic rods are provided, and the multiple second telescopic rods are distributed around the fixing plate.

[0016] Preferably, the compression locking assembly further includes a mounting groove. Mounting grooves are provided at both ends of the first clamping plate and the second clamping plate. A through groove extending into the second clamping plate is provided on the inner side of the mounting groove.

[0017] Preferably, the insert rod has a cylindrical groove inside, a sliding ring is slidably connected inside the cylindrical groove, a first spring is fixedly connected between the sliding ring and the insert rod, a round-headed locking block is fixedly connected to the outside of the sliding ring, and a concave groove is opened on the inner side of the fixing ring, the concave groove cooperating with the round-headed locking block.

[0018] Preferably, the inner part of the second fixing ring is provided with a strip groove, the outer side of the insertion rod is fixedly connected to a strip block, the strip block is slidably connected to the strip groove, and the bottom of the strip block is fixedly connected to a second spring.

[0019] Preferably, the film-piercing clamp further includes a locking and fixing assembly, which is installed between the first clamping plate and the second clamping plate and distributed on one side of the first clamping plate and the second clamping plate. The locking and fixing assembly includes a fixing block and a fixing slot. The fixing block is installed on the inner side of the first clamping plate and the fixing slot is installed on the inner side of the second clamping plate.

[0020] Preferably, a round-headed protrusion is slidably connected to the outer side of the fixing block, an elastic element is provided between the round-headed protrusion and the fixing block, and a groove that mates with the round-headed protrusion is provided on the inner side of the fixing slot.

[0021] Preferably, the flexible splint is made of rubber, and the surface of the flexible splint is provided with anti-slip texture.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. When the shaped plate and the cavity approach each other, the two flexible clamps first come into contact and then into contact with the composite current collector, thereby squeezing the flexible clamps. The flexible clamps are made of a flexible material and can be deformed under pressure, giving the first clamp and the second clamp space to move. Under the squeezing action, the composite current collector is fixed while avoiding delamination and damage to the membrane material. At the same time, the first clamp and the second clamp are hollowed out to reduce weight and facilitate membrane insertion.

[0024] 2. By providing adsorption holes communicating with the adsorption groove on the flexible clamping plate and the fixed plate, when the first clamping plate and the second clamping plate approach each other, the two ends of the insertion rod can contact the pressure plate of the first clamping plate and the second clamping plate respectively and squeeze the pressure plate to push the adsorption plate away from the fixed plate, thereby generating negative pressure inside the adsorption groove, which in turn adsorbs the composite current collector, which is beneficial to further fix the composite current collector. Furthermore, the wavy anti-slip texture of the flexible clamping plate and the negative pressure effect in the adsorption groove can enhance the surface friction of the flexible clamping plate, which is beneficial to further fix the composite current collector.

[0025] 3. When the round-headed locking block inside the insertion rod approaches the concave groove, the round-headed locking block enters the concave groove under the action of the first spring, thereby locking and fixing it. The sliding ring can limit the round-headed locking block to prevent it from falling off. The first spring facilitates the reset of the round-headed locking block. The round-headed protrusion cooperates with the concave groove. In the same way, the round-headed protrusion is locked into the groove, thereby fixing the first clamping plate and the second clamping plate. The compression locking assembly and the locking fixing assembly are arranged alternately. Magnets are set inside both fixing plates to further improve the interlocking effect.

[0045] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0046] This utility model provides, for example Figure 1-11 The membrane clamp shown includes:

[0047] The clamping assembly 001 is used to support the clamp and includes a first clamping plate 101 and a second clamping plate 102, wherein the first clamping plate 101 and the second clamping plate 102 are arranged opposite to each other. The first clamping plate 101 and the second clamping plate 102 are fixedly connected to the sides of each other. The four corners of the inner side of the second clamping plate 102 are fixedly connected to the limiting rods 104. The limiting rods 104 are slidably connected to the first clamping plate 101. The four corners of the first clamping plate 101 are provided with slots 106, which cooperate with the limiting rods 104. The end of the limiting rod 104 that passes through the slot 106 is fixedly connected to a stop block 105.

[0048] The negative pressure component 002 is provided in two sets, which are respectively installed inside the first clamping plate 101 and the second clamping plate 102. It includes a U-shaped plate 201, an adsorption plate 204 is fixedly connected to the outside of the U-shaped plate 201, and a pressure plate 205 is fixedly connected to the end of the U-shaped plate 201.

[0049] The extrusion assembly 003 includes a fixed plate 301. An adsorption groove 208 is provided inside the fixed plate 301. The adsorption groove 208 is slidably connected to the adsorption plate 204. A flexible clamping plate 303 is fixedly connected to the inner side of the fixed plate 301. The flexible clamping plate 303 can clamp the membrane material over a large area to improve the membrane material's stress resistance.

[0050] The compression locking assembly 004 is installed between the first clamping plate 101 and the second clamping plate 102 and is distributed at both ends. The compression locking assembly includes a plug rod 405.

[0051] The flexible clamp 303 is used to contact the composite current collector; the fixed plate 301 and the flexible clamp 303 are provided with holes that communicate with the adsorption tank 208. When the first clamp 101 and the second clamp 102 approach each other, the insertion rod 405 can contact the pressure plate 205 and squeeze the pressure plate 205 to push the adsorption plate 204 to move relative to the fixed plate in the adsorption tank so as to generate negative pressure in the adsorption tank to adsorb the composite current collector.

[0052] In use, the user can hold the two handles 103 to move the first clamping plate 101 and the second clamping plate 102 away from each other. The stop block 105 is magnetically connected to the first clamping plate 101 (such as a magnet) to fix the first clamping plate 101. Then, the user can pass the end of the mold material between the first clamping plate 101 and the second clamping plate 102. Due to the limited magnetic attraction, the user should press the first clamping plate 101 to bring it closer to the second clamping plate 102, so that the two flexible clamping plates 303 come closer to each other and fit against the film material, thereby fixing the film material. Then, the user can hold the handles 103 and pull the device to move the film material through the roller system. This can be operated in a small environment. It should be noted that the device shown in the figure is for schematic purposes only, and the length of the device can be extended as needed. The first clamping plate 101 and the second clamping plate 102 are hollowed out to reduce weight and facilitate film threading. When clamping, the second clamping plate 102 and the first clamping plate 101 approach each other, and the two flexible clamping plates 303 first come into contact with the membrane material, thereby squeezing the flexible clamping plates 303. When the fixed plate 301 abuts against the first clamping plate 101, the fixed plate 301 remains stationary relative to the first clamping plate 101. At this time, the two ends of the insertion rod 405 come into contact with the pressure plates 205 of the first clamping plate 101 and the second clamping plate 102 respectively and squeeze the pressure plates 205 to push the adsorption plate 204 to move away from the fixed plate 301 inside the adsorption tank 208, thereby generating negative pressure inside the adsorption tank 208, which in turn adsorbs the membrane material, which is beneficial for further fixing the membrane material.

[0053] Limiting rods 104 are fixedly connected to the four inner corners of the second clamping plate 102. A stop block 105 is fixedly connected to the end of the limiting rod 104. Slots 106 are provided at the four corners of the first clamping plate 101. The slots 106 cooperate with the limiting rods 104. The limiting rods 104 pass through the slots 106 to facilitate the limiting movement between the first clamping plate 101 and the second clamping plate 102.

[0054] Furthermore, both the first clamping plate 101 and the second clamping plate 102 have cavities 202 inside, and the outer side of the cavity 202 has a slot 203. The C-shaped plate 201 cooperates with the cavity 202, and the C-shaped plate 201 is slidably connected to the slot 203. The inner side of both the first clamping plate 101 and the second clamping plate 102 is equipped with a first telescopic rod 206. The first telescopic rod 206 is fixedly connected to the inner side of the adsorption plate 204, and a first return spring 207 is sleeved on the outer side of the first telescopic rod 206. In the initial state, both the first return spring 207 and the second return spring 307 are in the extended state. When the second clamping plate 102 and the first clamping plate 101 approach each other, the two flexible clamping plates 303 first contact and then contact the membrane material, thereby squeezing the flexible clamping plates 303. The flexible clamping plates 303 drive the adsorption plate 204 to retract inward, thereby squeezing the first telescopic rod 206. The first telescopic rod 206 retracts and squeezes the first return spring 207, causing the flexible clamping plates 303 to drive the adsorption plate 204 to be squeezed inward as a whole. At this time, the insertion rod... 405 Squeezes the pressure plate 205, causing the adsorption plate 204 to press the first telescopic rod 206 inward. At this time, the fixed plate 301 abuts against the first clamping plate 101, and the adsorption plate 204 moves away from the fixed plate 301 inside the adsorption tank 208. The soft clamping plate 303 is made of soft material and can be deformed under pressure, providing space for the first clamping plate 101 and the second clamping plate 102 to move. The movement of the adsorption plate 204 causes a negative pressure to be generated inside the fixed plate 301, thereby adsorbing the membrane material, which is beneficial for further fixing the membrane material.

[0055] A second telescopic rod 306 connects the inner side of the fixed plate 301 to the adsorption plate 204. A second return spring 307 is sleeved on the outer side of the second telescopic rod 306. Multiple second telescopic rods 306 are arranged around the fixed plate 301. When the adsorption plate 204 slides inside the adsorption tank 208, it presses the second telescopic rod 306, causing it to retract and compress the second return spring 307. The second return spring 307 automatically resets when the device is opened. A rubber ring is provided between the adsorption plate 204 and the fixed plate 301.

[0056] Because the insertion rod 405 is relatively long, in order not to affect the fixation of the membrane material, the compression locking assembly 004 is distributed at both ends of the device. The compression locking assembly 004 includes a mounting groove 401. Mounting grooves 401 are provided at both ends of the first clamping plate 101 and the second clamping plate 102. A through groove 402 is provided on the inner side of the mounting groove 401, which extends into the second clamping plate 102. A fixing ring 403 is fixedly connected in the mounting groove 401 inside the second clamping plate 102. A fixing ring 406 is fixedly connected in the mounting groove 401 inside the first clamping plate 101. The insertion rod 405 is slidably connected to the inside of the fixing ring 406. The other end of the insertion rod 405 is engaged with the fixing ring 403.

[0057] In the initial state, the first clamping plate 101 and the second clamping plate 102 are far apart, and the insertion rod 405 is not in contact with the fixing ring 403. When the first clamping plate 101 and the second clamping plate 102 move closer together, the insertion rod 405 gradually inserts into the interior of the fixing ring 403. The end of the insertion rod 405 first contacts the pressure plate 205 inside the first clamping plate 101. As the first clamping plate 101 and the second clamping plate 102 continue to move closer together, when the insertion rod 405 is compressed, it squeezes the second spring 413, causing the other end of the insertion rod 405 to contact the pressure plate 205 inside the second clamping plate 102, thereby pushing the ring. The shape plate 201 and the adsorption plate 204 move, causing the device to adsorb the membrane material. Then, the first clamping plate 101 and the second clamping plate 102 continue to move closer to each other. When the second spring 413 is squeezed to the extreme point, the round-headed locking block 410 inside the insertion rod 405 approaches the concave groove 404. When the round-headed locking block 410 is in contact with the concave groove 404, the round-headed locking block 410 enters the interior of the concave groove 404 under the action of the first spring 408, thereby locking and fixing. The end of the round-headed locking block 410 and the inner wall of the concave groove 404 are provided with mutually attractive magnetic blocks, which enhance the stability of the locking by mutual attraction.

[0058] The insert rod 405 has a cylindrical groove 407 inside, and a sliding ring 409 is slidably connected inside the cylindrical groove 407. A first spring 408 is fixedly connected between the sliding ring 409 and the insert rod 405. A round-headed locking block 410 is fixedly connected to the outside of the sliding ring 409. A concave groove 404 is opened on the inside of the fixing ring 403. The concave groove 404 cooperates with the round-headed locking block 410. When the round-headed locking block 410 inside the insert rod 405 approaches the concave groove 404, the round-headed locking block 410 enters the concave groove 404 under the action of the first spring 408, thereby locking and fixing. Under the action of magnetic attraction, it is more stable. The sliding ring 409 can limit the round-headed locking block 410 to prevent it from falling off. When disassembly is required, simply hold the handle 103 with both hands and pull the first clamp 101 and the second clamp 102 apart to make the round-headed locking block 410 move away from the concave groove 404.

[0059] The inner part of the fixing ring 406 is provided with a strip groove 411. A strip block 412 is fixedly connected to the outer side of the insertion rod 405. The strip block 412 is slidably connected to the strip groove 411. A second spring 413 is fixedly connected to the bottom of the strip block 412. When the outer end of the insertion rod 405 is subjected to pressure, it will squeeze the second spring 413, causing the second spring 413 to retract backward, so that the insertion rod 405 can abut against the pressure plates 205 at both ends. The second spring 413 has a small elastic force. Only when squeezed to the extreme can the round head block 410 and the concave groove 404 cooperate.

[0060] The membrane clamp also includes a locking and fixing assembly 005, which is installed between the first clamping plate 101 and the second clamping plate 102 and is located on one side of the first clamping plate 101 and the second clamping plate 102. The locking and fixing assembly 005 includes a fixing block 501 and a fixing slot 502. The fixing block 501 is installed on the inner side of the first clamping plate 101 and the fixing slot 502 is installed on the inner side of the second clamping plate 102. A round-headed protrusion is slidably connected to the outer side of the fixing block 501. An elastic element is provided between the round-headed protrusion and the fixing block 501. A groove is provided on the inner side of the fixing slot 502 to cooperate with the round-headed protrusion. When the round-headed block 410 cooperates with the concave groove 404, the round-headed protrusion cooperates with the groove, which is the same principle as the locking block 410 and the concave groove 404. The end of the round-headed protrusion and the inside of the groove are provided with mutually attractive magnetic blocks, which is the same principle as the round-headed block 410 and the concave groove 404. When the round-headed protrusion cooperates with the groove, the round-headed protrusion is inserted into the groove under the action of the elastic element. Then, through the action of the magnetic block, the round-headed protrusion and the groove are more stable, thereby fixing the first clamping plate 101 and the second clamping plate 102. When disassembly is required, simply hold the handle 103 with both hands and pull the first clamping plate 101 and the second clamping plate 102 apart to make the protrusion move away from the groove.

[0061] The flexible clamp 303 is made of soft rubber material, and its surface is textured with anti-slip patterns. Specifically, both the fixing plate 301 and the flexible clamp 303 have adsorption holes that communicate with the adsorption tank. The adsorption plate 204 can move relative to the fixing plate within the adsorption tank 208, creating negative pressure within the tank to adsorb the membrane material and enhance its fixation. Notably, to ensure the adsorption holes are not affected, there are no anti-slip patterns within one centimeter around them. Both the anti-slip patterns and the negative pressure enhance the surface friction of the flexible clamp 303, further facilitating membrane material fixation.

[0062] At this time, under the combined action of elastic compression, air pressure adsorption and anti-slip texture, the membrane material is in close contact with the soft clamp 303, which helps to enhance fixation and prevent membrane delamination.

[0063] Magnets are installed inside both fixing plates 301 to further improve the interlocking effect.

[0064] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
