Description

Technical Field

[0001] This application relates to the field of crimping technology, and in particular to a crimping device. Background Technology

[0002] Die-cast aluminum chassis are widely used in electronic equipment manufacturing. To improve their electromagnetic shielding or heat insulation performance, aluminum foil is often pasted onto the bottom of the chassis. However, traditional processes rely on manual operation, which suffers from low efficiency, air bubbles and wrinkles in the aluminum foil leading to low yield, and difficulty in ensuring full and uniform contact between the aluminum foil and the bottom of the chassis. Furthermore, frequent fixture changes are required for chassis of different sizes, resulting in difficulties in changeovers and long downtime. Utility Model Content

[0003] Therefore, it is necessary to provide a crimping device to address the above problems, so as to improve the bonding efficiency and quality of the crimping device, shorten the changeover time, and reduce the equipment investment cost.

[0004] This utility model provides a crimping device for crimping a film onto a chassis, comprising:

[0005] A support mechanism, comprising a support member and a positioning member, wherein the support member has a receiving cavity for accommodating the chassis, and the positioning member is detachably disposed on the inner wall of the receiving cavity; and

[0006] A clamping mechanism, comprising a pressing component capable of reciprocating along a first preset direction to move closer to or further away from the bearing mechanism.

[0007] The aforementioned crimping device stably supports the chassis through the receiving cavity of the bearing mechanism and precisely positions the chassis using detachable positioning components, ensuring accurate crimping position. The crimping components of the pressing mechanism move along a first preset direction, ensuring full and uniform contact between the film and the chassis surface, guaranteeing crimping stability and controllability, reducing the occurrence of bubbles and wrinkles in the film, and improving yield. The detachable positioning component design allows users to replace positioning components of different sizes according to the chassis dimensions, enabling the receiving cavity and positioning components to adapt to chassis of different sizes without frequent replacement of the entire dedicated fixture, shortening changeover time and improving the flexibility and versatility of the device.

[0008] In one embodiment, the receiving cavity and the chassis are square, and there are two positioning members, which are respectively disposed at a pair of opposite corners of the receiving cavity.

[0009] This configuration, with diagonally positioned positioning elements forming stable positioning fulcrums, effectively restricts the translation and rotation of the chassis within the housing cavity, improving positioning accuracy and making it suitable for the standardized crimping requirements of square chassis.

[0010] In one embodiment, the positioning member includes a fixing part and a positioning part, the fixing part being fixed to the upper surface of the carrier member and the positioning part being fixed to the inner wall of the receiving cavity.

[0011] This configuration, with the positioning part fixed to the upper surface of the carrier, allows the positioning part to be securely installed on the carrier, while also facilitating the installation and removal of the positioning part; the positioning part fits tightly against the chassis, further improving positioning accuracy.

[0012] In one embodiment, the positioning part has a mating surface on the side opposite to the inner wall of the receiving cavity for cooperating with the chassis.

[0013] With this configuration, the mating surface of the positioning part is adapted to the shape of the outer surface of the chassis. By increasing the positioning contact area through surface contact, the positioning gap is reduced, which further improves the positioning stability of the chassis in the cavity and avoids the chassis shifting during the pressing process.

[0014] In one embodiment, the fixing part is fixed to the carrier by fasteners.

[0015] This design allows for a detachable connection between the positioning part and the carrier component via fasteners, facilitating disassembly while ensuring connection reliability.

[0016] In one embodiment, the pressing mechanism further includes a driving component, the pressing component is disposed at the output of the driving component, and the driving component is capable of driving the pressing component to reciprocate along a first preset direction.

[0017] With this configuration, the drive component can provide stable power to the crimping component, ensuring that the crimping component can accurately complete the crimping operation, thus ensuring the stability and controllability of the crimping process, while improving the automation level of the crimping device.

[0018] In one embodiment, the crimping assembly includes a crimping member and a silicone buffer layer, the silicone buffer layer being disposed on the side of the crimping member facing the support mechanism.

[0019] With this configuration, the silicone buffer layer can provide a cushioning effect during the crimping process, preventing excessive local stress from damaging the membrane or chassis, while ensuring that the crimping membrane can be evenly adhered to the chassis surface, thus improving the crimping quality.

[0020] In one embodiment, the crimping assembly includes a crimping member, the side of which facing the support mechanism has a curved surface for fitting with the chassis.

[0021] This design, with its curved surface, allows the working surface of the crimping component to match the surface shape of the chassis, ensuring that the crimping component can fit snugly against the chassis surface and apply pressure evenly, thus further improving the crimping quality.

[0022] In one embodiment, the crimping device further includes a conveying mechanism, and the carrying mechanism is disposed on the conveying mechanism. The conveying mechanism can drive the carrying mechanism to reciprocate along a second preset direction to move closer to or away from the crimping position.

[0023] This setup enables automatic transport of the bearing mechanism via a conveying mechanism, which works in conjunction with the pressing mechanism to form an assembly line operation. This improves the automation level of the pressing process and increases the maximum distance between the bearing mechanism and the pressing mechanism, facilitating the replacement of the casing and positioning components.

[0024] In one embodiment, the conveying mechanism includes a linear guide rail extending along a second preset direction, and the bearing mechanism is slidably disposed on the linear guide rail.

[0025] This configuration allows the linear guide to provide a stable sliding track for the load-bearing mechanism, ensuring its stability during movement and improving the reliability and crimping accuracy of the device. Simultaneously, the linear guide, in conjunction with positioning components, enables precise positioning and rapid changeover of the chassis, shortening equipment adjustment time.

[0037] Die-cast aluminum chassis are widely used in electronic equipment manufacturing. To improve their electromagnetic shielding or heat insulation performance, aluminum foil is often pasted on the bottom of the chassis. However, traditional processes rely on manual operation, which has many problems such as low efficiency of manual pasting, easy formation of air bubbles and wrinkles in the aluminum foil leading to low yield, difficulty in ensuring full and uniform contact between the aluminum foil and the bottom of the chassis, and frequent changes of fixtures for chassis of different sizes, resulting in difficulties in changeover and long downtime.

[0038] To solve the above problems, such as Figures 1 to 4 As shown, this utility model provides a crimping device to improve the bonding efficiency and quality of the crimping device, shorten the changeover time, and reduce equipment investment costs.

[0039] like Figure 2 As shown, the Z-axis direction in the diagram is defined as the first preset direction, and the X-axis direction in the diagram is defined as the second preset direction.

[0040] like Figures 1 to 3 As shown, this application provides a crimping device. The crimping device provided in this application is used to crimp a film onto a chassis 200, wherein the film can be a metal film such as aluminum foil, a plastic film, etc. The crimping device includes a supporting mechanism 1 and a pressing mechanism 2. The supporting mechanism 1 includes a supporting member 11 and a positioning member 12. The supporting member 11 has a receiving cavity 111 for accommodating the chassis 200, and the positioning member 12 is detachably disposed on the inner wall of the receiving cavity 111. The pressing mechanism 2 includes a crimping assembly 22, which reciprocates along a first preset direction, moving closer to or away from the supporting mechanism 1. The receiving cavity 111 of the supporting mechanism 1 stably supports the chassis 200, and the positioning member 12 precisely positions the chassis 200, ensuring the accuracy of the crimping position; when the supporting mechanism 1 is in the crimping position, the crimping assembly 22 can press evenly and comprehensively onto the film. When pressing the film onto the chassis 200, the film is first placed on the surface of the chassis 200. Then, the pressing assembly 22 is controlled to move along a first preset direction and press evenly onto the film, ensuring that the film makes full and uniform contact with the surface of the chassis 200. This guarantees pressing stability and controllability, reduces the occurrence of bubbles and wrinkles in the film, and improves the yield rate. The detachable design of the positioning component 12 allows users to replace different sizes of positioning components 12 according to the size of the chassis 200. This allows the receiving cavity 111 to fit different sizes of chassis 200 without frequently changing the entire dedicated fixture, shortening changeover time and improving the flexibility and versatility of the device.

[0041] like Figures 2 to 3 As shown, in one embodiment, the receiving cavity 111 and the chassis 200 are square, and there are two positioning members 12, which are respectively arranged at a pair of opposite corners of the receiving cavity 111. The positioning members 12 arranged diagonally can form stable positioning fulcrums, effectively restricting the translation and rotation of the chassis 200 within the receiving cavity 111, improving positioning accuracy, and are suitable for the standardized crimping requirements of square chassis.

[0042] In another embodiment, the receiving cavity 111 and the chassis 200 can be circular, elliptical, polygonal, or irregular in shape.

[0043] In another embodiment, the number and arrangement of the positioning elements 12 can be adjusted according to the shape of the receiving cavity 111 and the chassis 200. The positioning elements 12 can be set at the four corners of the receiving cavity 111, or evenly distributed along the edge of the receiving cavity 111, to adapt to chassis 200 of different shapes. In addition, for circular chassis, two or more positioning elements 12 can be arranged in a ring, or for irregularly shaped chassis, multiple positioning elements 12 adapted to the contour can be used to ensure the stable placement of chassis 200 of different shapes through multi-point positioning.

[0044] like Figures 2 to 4 As shown, in one embodiment, the positioning member 12 includes a fixing part 121 and a positioning part 122. The fixing part 121 is fixed to the upper surface of the carrier member 11, and the positioning part 122 is fixed to the inner wall of the receiving cavity 111. The fixing part 121 to the upper surface of the carrier member 11 facilitates the installation and removal of the positioning member 12, while ensuring the reliable fixing of the positioning part 122 to the inner wall of the receiving cavity 111, so that the positioning member 12 can be firmly installed on the carrier member 11. At the same time, the positioning part 122 can fit tightly against the outer surface of the chassis 200, further improving the positioning accuracy.

[0045] In another embodiment, the positioning member 12 includes only the positioning part 122, which is fixed between the inner wall of the receiving cavity 111 and the chassis 200. The positioning of the chassis 200 is achieved by the pressure of the positioning part 122 on the chassis 200.

[0046] In another embodiment, the positioning member 12 includes only the positioning part 122, which can be fixed to the inner wall of the receiving cavity 111 by means of fasteners, snaps, magnetic attraction, etc.

[0047] like Figures 2 to 4 As shown, in one embodiment, the fixing part 121 is fixed to the carrier 11 by fasteners. The fastener connection enables a detachable connection between the positioning part 122 and the carrier 11, facilitating disassembly while ensuring connection reliability. The fasteners can be screws, bolts, rivets, pins, or other standard or custom fasteners.

[0048] In another embodiment, the fixing part 121 can adopt a quick installation structure such as snap-on or magnetic, so that the positioning part 12 can be disassembled and assembled without tools, thereby further improving the efficiency of model changeover.

[0049] In another embodiment, the fixing part 121 can be made of magnetic material and magnetically attached to the carrier 11, which facilitates the quick installation and removal of positioning parts 12 of different specifications to adapt to different chassis 200.

[0050] In one embodiment, the fixing part 121 and the positioning part 122 are integrally formed, which facilitates manufacturing. In another embodiment, the fixing part 121 and the positioning part 122 can be connected by threads, snap-fit ​​connections or welding to meet different strength and stability requirements.

[0051] like Figures 2 to 4 As shown, in one embodiment, the positioning part 122 has a mating surface 1221 on the side opposite to the inner wall of the receiving cavity 111 for mating with the chassis 200. The mating surface 1221 of the positioning part 122 is adapted to the shape of the outer surface of the chassis 200, increasing the positioning contact area and reducing the positioning gap through surface contact, thereby further improving the stability of the chassis 200 in the receiving cavity 111 and preventing the chassis 200 from shifting during the pressing process.

[0052] In another embodiment, the mating surface 1221 of the positioning part 122 can be configured as a serrated, corrugated or other anti-slip structure, or elastic buffer material can be pasted on the mating surface 1221 to adapt to the small tolerances of the chassis 200 surface and enhance the friction and buffering effect during positioning.

[0053] In another embodiment, the mating surface 1221 of the positioning part 122 can be designed to be adjustable, such as a threaded adjustment structure, a sliding adjustment structure or a telescopic structure, to accommodate chassis 200 of different sizes.

[0054] In another embodiment, the positioning element 12 can also be fixed to the inner wall of the receiving cavity 111 by an elastic connection to adapt to slight changes in the size of the chassis 200 and further improve positioning accuracy. For example, the positioning element 12 can adopt a spring-loaded structure, so that when the chassis 200 is placed into the receiving cavity 111, the positioning element 12 can automatically adjust its position to ensure a tight fit with the chassis 200.

[0055] In another embodiment, the positioning part 122 may be made of a flexible material, such as rubber or silicone, to adapt to the outer surface of the chassis 200 of different shapes, further improving the fit.

[0056] like Figure 2As shown, in one embodiment, the pressing mechanism 2 further includes a drive assembly 21, and a pressing assembly 22 is disposed at the output portion 211 of the drive assembly 21. The drive assembly 21 can drive the pressing assembly 22 to reciprocate along a first preset direction. The drive assembly 21 can provide stable power to the pressing assembly 22, ensuring that the pressing assembly 22 can accurately complete the pressing operation, while improving the automation level of the pressing device. By driving the pressing assembly 22 to reciprocate, the stability and controllability of the pressing process are ensured.

[0057] The drive assembly 21 can be configured with different drive methods depending on the crimping accuracy and load requirements, such as motor drive, pneumatic / hydraulic drive, or screw and nut mechanism. When the drive assembly 21 is a cylinder assembly, its stroke can be controlled by a solenoid valve, and the output pressure is adjustable between 0.1MPa and 0.5MPa. Preferably, the drive assembly 21 can drive the crimping assembly 22 to press the aluminum foil at a pressure of 0.3MPa for 2 seconds.

[0058] In another embodiment, the pressing mechanism 2 includes a manually driven pressing assembly 22, which is provided with a hand-held part that is easy for workers to operate. The pressing mechanism 2 can be reciprocated along a first preset direction by the worker operating the hand-held part.

[0059] In one embodiment, the driving assembly 21 further includes a guide rod 212 extending along a first preset direction. The pressing assembly 22 is slidably disposed on the guide rod 212, and the guide rod 212 is used to guide the pressing assembly 22 to move along the first preset direction. Guided by the guide rod 212, the pressing assembly 22 can be effectively prevented from deflecting or wobbling during movement, ensuring that the pressing assembly 22 always moves along a predetermined straight trajectory, thereby achieving uniform pressing of the film and improving the pressing quality.

[0060] like Figures 1 to 2 As shown, in one embodiment, the crimping assembly 22 includes a crimping member 221, the side of the crimping member 221 facing the support mechanism 1 having a curved surface adapted to the chassis 200. The curved surface design allows the working surface of the crimping member 221 to match the surface shape of the chassis 200, ensuring that the crimping member 221 can fit against the surface of the chassis 200, applying pressure evenly, and further improving the crimping quality.

[0061] In another embodiment, the crimping member 221 can be designed to be detachable, allowing for the replacement of the corresponding crimping member 221 for different curved surface shapes.

[0062] In another embodiment, the crimping member 221 can be made of a flexible material, the self-adaptability of which allows it to adapt to a certain range of surface changes without replacing the crimping member 221.

[0063] like Figures 1 to 2As shown, in one embodiment, the crimping assembly 22 further includes a silicone buffer layer 222, which is disposed on the side of the crimping member 221 facing the support mechanism 1. The silicone buffer layer 222 provides cushioning during the crimping process, preventing excessive local stress from damaging the membrane or chassis 200, while ensuring that the crimped membrane adheres evenly to the surface of the chassis 200, thus improving the crimping quality. Preferably, the silicone buffer layer 222 has a thickness of 5mm-8mm and a Shore hardness of 30A-50A.

[0064] In another embodiment, the buffer layer can be made of other elastic materials, such as rubber or foam. The hardness and thickness of the buffer layer can be adjusted according to the material and thickness of the membrane to adapt to membranes and chassis 200 of different materials.

[0065] In another implementation, the buffer layer can be designed as a multi-layered structure, achieving multi-level cushioning through a combination of materials with different hardness. For example, the buffer layer can be a double-layered structure, with a softer outer layer and a harder inner layer to provide initial cushioning and subsequent support.

[0066] like Figures 1 to 3 As shown, in one embodiment, the crimping device further includes a conveying mechanism 3, with a carrying mechanism 1 disposed on the conveying mechanism 3. The conveying mechanism 3 can drive the carrying mechanism 1 to reciprocate along a second preset direction to move closer to or away from the crimping position. The conveying mechanism 3 realizes automatic conveying of the carrying mechanism 1, forming a production line operation in conjunction with the pressing mechanism 2, improving the automation level of the crimping process, and increasing the maximum distance between the carrying mechanism 1 and the pressing mechanism 2 to facilitate the replacement of the housing 200 and the positioning component 12. Specifically, taking the first preset direction and the second preset direction as examples, when the carrying mechanism 1 moves to the crimping position along the second preset direction, the carrying mechanism 1 is located directly below the crimping assembly 22. When the crimping assembly 22 moves along the first preset direction toward the side closer to the carrying mechanism 1, it can press evenly and comprehensively onto the film. When the carrying mechanism 1 is pulled out to the crimping position along the second preset direction, there is more operating space for replacing the housing 200 and the positioning component 12.

[0067] like Figure 2 As shown, in one embodiment, the conveying mechanism 3 includes a linear guide rail 31 extending along a second preset direction, and the carrying mechanism 1 is slidably mounted on the linear guide rail 31. The linear guide rail 31 provides a stable sliding track for the carrying mechanism 1, ensuring that the carrying mechanism 1 remains stable during movement, thus improving the reliability and pressing accuracy of the device. Simultaneously, the linear guide rail 31, in conjunction with the positioning element 12, enables precise positioning and rapid changeover of the housing 200, shortening the adjustment time of the pressing device. Preferably, the linear guide rail 31 is a high-precision ball-bearing linear guide rail with a repeatability accuracy of less than or equal to 0.02 mm.

[0068] In another embodiment, the conveying mechanism 3 can adopt a pneumatic / hydraulic drive structure, chain drive, gear rack and pinion structure, etc. Different conveying methods can be selected according to the production cycle and accuracy requirements. For example, a high-speed production line can use a chain conveyor driven by a servo motor, and a high-precision positioning can use a linear motor for direct drive.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
