Abstract
Description
Technical Field
[0001] This application relates to the field of copper foil tension testing technology, specifically a tension testing device for copper foil. Background Technology
[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board. As a conductor in the PCB, it easily adheres to the insulating layer, receives the printed protective layer, and is etched to form the circuit pattern. Currently, tension testing is performed on the copper foil after production.
[0003] Chinese Patent Publication No. CN219475213U discloses a tension detection device for electronic copper foil. This solution includes a pressure plate, a threaded hole, and a threaded rod. The threaded connection between the threaded hole and the threaded rod allows the pressure plate to quickly fix the copper foil by rotating the threaded rod. Furthermore, the use of a pressure bearing prevents the pressure plate from rotating with the threaded rod, effectively securing the copper foil. Simultaneously, a tension measuring plate, a hydraulic rod, and a slider are used. The hydraulic rod's pushing force causes the slider to move the U-shaped mounting bracket and the copper foil to the right. The tension measuring plate measures the tension of the copper foil. This combination of operations solves the problems mentioned above regarding the cumbersome fixation of the copper foil and the reduced detection speed.
[0004] In the above scheme, the pressure plate is moved downward by rotating the threaded rod, thereby quickly fixing the copper foil. However, as the tension test proceeds, the part of the copper foil fixed by the pressure plate is subjected to a large tensile force, which can easily cause the copper foil to fall off, thus interrupting the copper foil tension test and affecting the normal progress of the copper foil test.
[0005] Therefore, it is necessary to provide a tension testing device for copper foil to solve the above problems.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content
[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is: to provide a copper foil tension testing device, in which a moving block synchronously drives a telescopic column to move during the copper foil tension testing process, causing the piston at one end of the telescopic column to slide in the fixed cylinder, thereby discharging gas into multiple mounting slots to apply pressure to the moving block, thereby compressing the spring and increasing the elastic force on the limiting block. As the moving block continues to move, the elastic force applied by the limiting block to the copper foil gradually increases, thereby improving the fixing effect, reducing the occurrence of copper foil detachment at both ends during the copper foil testing process, and ensuring the normal operation of the copper foil tension testing.
[0008] The technical solution adopted by this application to solve its technical problem is as follows: a tension testing device for copper foil, including a worktable, a fixed block installed on the top of the worktable, and a movable block that can move horizontally installed on the top of the worktable. A baffle is installed on the top of the worktable, and a pair of pressurizing mechanisms are installed on one side of the baffle. Limiting mechanisms are installed on the top of both the fixed block and the movable block. The limiting mechanism includes a lifting block that can move vertically.

Limiting blocks are slidably connected inside the multiple mounting slots, and multiple movable blocks are slidably connected inside the multiple mounting slots. A spring is installed between the movable block and the limiting block, and an air collection groove connected to the multiple mounting slots is opened inside the lifting block. When the movable block moves away from the fixed block, the two pressurizing mechanisms inject air into the air collection grooves in the two limiting mechanisms respectively.

[0011] Furthermore, the pressurization mechanism includes a fixed cylinder and a telescopic column. The fixed cylinder is installed on one side of the baffle, and the telescopic column is installed on one side of the moving block. One end of the telescopic column extends into the inner cavity of the fixed cylinder and is fitted with a piston. The piston matches the inner cavity of the fixed cylinder.
[0012] Furthermore, a connecting pipe is installed on the outer wall of the fixed cylinder and communicates with it. The end of the connecting pipe away from the fixed cylinder is connected to the lifting block, and the connecting pipe is connected to the air collection groove.
[0013] Furthermore, both the moving block and the fixed block are equipped with clamps on their tops, and the tops of the clamps are engraved with anti-slip textures.
[0014] Furthermore, a pair of slide rails are installed on the top of the workbench, the moving block is slidably connected to the pair of slide rails, and a lead screw is rotatably connected to one side of the fixed block. A screw sleeve matching the lead screw is installed inside the moving block.
[0015] Furthermore, the top of the workbench is engraved with scale lines, and a pointer is installed on one side of the moving block.
[0016] The beneficial effects of this application are as follows: The copper foil tension testing device provided by this application, during the copper foil tension testing process, the moving block synchronously drives the telescopic column to move, causing the piston at one end of the telescopic column to slide in the fixed cylinder, thereby discharging gas into multiple mounting slots to apply pressure to the moving block, thereby compressing the spring and increasing the elastic force on the limiting block. As the moving block continues to move, the elastic force applied by the limiting block to the copper foil gradually increases, thereby improving the fixing effect, reducing the occurrence of copper foil falling off at both ends during the copper foil testing process, and ensuring the normal operation of the copper foil tension testing.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0029] like Figure 1-5 As shown, this application provides a tension testing device for copper foil, including a worktable 1. A fixing block 2 is installed on the top of the worktable 1, and the fixing block 2 is fixed to the top of the worktable 1 by bolts. A movable block 3 that can move in the horizontal direction is installed on the top of the worktable 1. A baffle 7 is installed on the top of the worktable 1, and the baffle 7 is fixed to the top of the worktable 1 by bolts. A pair of pressure boosting mechanisms 6 are installed on one side of the baffle 7. Limiting mechanisms 4 are installed on the top of both the fixing block 2 and the movable block 3. The limiting mechanism 4 includes a lifting block 4 that can move in the vertical direction. 1. The lifting block 41 has multiple mounting slots 48 inside, and each mounting slot 48 is slidably connected to a limiting block 46. Each mounting slot 48 is also slidably connected to multiple movable blocks 49. The movable blocks 49 match the mounting slots 48. A spring 410 is installed between the movable blocks 49 and the limiting blocks 46. The lifting block 41 has an air collection groove 45 inside that communicates with the multiple mounting slots 48. When the moving block 3 moves away from the fixed block 2, the two pressurizing mechanisms 6 inject air into the air collection grooves 45 in the two limiting mechanisms 4 respectively.
[0030] In this embodiment, the proposed solution is a device for tension testing of copper foil after production. Specifically, by placing both ends of the copper foil on the fixed block 2 and the movable block 3 respectively, and then rotating the two screws 44 to control the lifting block 41 to descend until the lifting block 41 abuts against the copper foil, the limiting block 46 is squeezed and moves into the mounting groove 48, and the bottom of the limiting block 46 is level with the bottom of the lifting block 41, thereby completing the fixation of both ends of the copper foil. Then, the movable block 3 is controlled to move away from the fixed block 2 to apply tension to the copper foil, thereby performing tension testing on the copper foil. During the movement of the movable block 3, gas can be injected into the gas collecting groove 45, and the gas is discharged into the mounting groove 48, thereby applying pressure to the movable block 49, causing it to move downward, thereby compressing the spring 410 and increasing the elastic force on the limiting block 46. As the movable block 3 continues to move, the elastic force applied by the limiting block 46 to the copper foil gradually increases, thereby improving the fixing effect and reducing the occurrence of copper foil detachment at both ends during the copper foil testing process.
[0031] like Figure 4-5As shown, the lifting block 41 has multiple connecting holes 47 inside, and the air collection groove 45 is connected to multiple mounting grooves 48 through the multiple connecting holes 47.
[0032] In this embodiment, the gas in the gas collection groove 45 can be discharged into the multiple mounting grooves 48 through multiple connecting holes 47 respectively.
[0033] like Figure 3 As shown, the limiting mechanism 4 also includes a top plate 43, with a screw 44 threadedly connected to the top of the top plate 43, and a pair of slide rods 42 installed at the bottom of the top plate 43. The lifting block 41 is slidably connected to the pair of slide rods 42, and the bottom end of the screw 44 is rotatably connected to the lifting block 41. The slide rods 42 are installed on the top of the moving block 3 and the fixed block 2 by welding.
[0034] In this embodiment, the lifting block 41 can be moved vertically by rotating the screw 44, thereby fixing the copper foil.
[0035] like Figure 2-3 As shown, the pressurization mechanism 6 includes a fixed cylinder 61 and a telescopic column 62. The fixed cylinder 61 is installed on one side of the baffle 7 and is fixed to the baffle 7 by bolts. The telescopic column 62 is installed on one side of the moving block 3 and is fixed to the telescopic column 62 by bolts. One end of the telescopic column 62 extends into the inner cavity of the fixed cylinder 61 and is fitted with a piston. The piston matches the inner cavity of the fixed cylinder 61. A connecting pipe 63 is installed on the outer wall of the fixed cylinder 61 and communicates with it. The end of the connecting pipe 63 away from the fixed cylinder 61 is connected to the lifting block 41, and the connecting pipe 63 is connected to the air collection groove 45.
[0036] In this embodiment, when the moving block 3 moves away from the fixed block 2, the moving block 3 synchronously drives the telescopic column 62 to move, so that the piston at one end of the telescopic column 62 slides in the fixed cylinder 61, thereby discharging the gas through the connecting pipe 63 into the gas collection groove 45, and then discharging it into multiple mounting grooves 48 respectively.
[0037] like Figure 3 As shown, a clamping plate 10 is installed on the top of both the moving block 3 and the fixed block 2. The clamping plate 10 is fixed to the top of the moving block 3 and the fixed block 2 by bolts. Anti-slip texture is engraved on the top of the clamping plate 10.
[0038] In this embodiment, the copper foil can be placed on top of the clamping plate 10, and the anti-slip texture can improve the friction between the copper foil and the clamping plate 10.
[0039] like Figure 1-2 As shown, a pair of slide rails 5 are installed on the top of the workbench 1. The slide rails 5 are fixed to the top of the workbench 1 by bolts. The moving block 3 is slidably connected to the pair of slide rails 5. A lead screw 8 is rotatably connected to one side of the fixed block 2. A threaded sleeve matching the lead screw 8 is installed inside the moving block 3.
[0040] In this embodiment, the moving block 3 can be driven to move horizontally by rotating the lead screw 8.
[0041] like Figure 1 As shown, the top of the workbench 1 is engraved with scale lines 9, and a pointer is installed on one side of the moving block 3.
[0042] In this embodiment, as the moving block 3 moves away from the fixed block 2, the value indicated by the pointer on the scale line 9 can be observed simultaneously. This value directly reflects the current tension of the copper foil. By recording and analyzing these values, the tension of the copper foil can be detected.
[0043] Working principle:
[0044] By placing both ends of the copper foil on the fixed block 2 and the movable block 3 respectively, and then rotating the two screws 44 to control the lowering block 41 to descend until the lowering block 41 abuts against the copper foil, the limiting block 46 is compressed and moves into the mounting groove 48, with the bottom of the limiting block 46 level with the bottom of the lifting block 41, thus completing the fixation of both ends of the copper foil. Next, by rotating the lead screw 8, the movable block 3 can be moved horizontally, controlling the movable block 3 to move away from the fixed block 2, applying tension to the copper foil, thereby detecting the tension of the copper foil. During the movement, the moving block 3 synchronously drives the telescopic column 62 to move, causing the piston at one end of the telescopic column 62 to slide inside the fixed cylinder 61, thereby discharging the gas through the connecting pipe 63 into the gas collection groove 45, and then into multiple mounting grooves 48, thereby applying pressure to the moving block 49, causing it to move downward, thereby compressing the spring 410 and increasing the elastic force on the limiting block 46. As the moving block 3 continues to move, the elastic force applied by the limiting block 46 to the copper foil gradually increases, thereby improving the fixing effect and reducing the occurrence of copper foil falling off at both ends during the copper foil detection process.
[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
