Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, in particular to a fixing device for copper foil tension detection. Background Art

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous layer of metal foil deposited on the base layer of the circuit board. As the conductor of the PCB, it easily adheres to the insulating layer, accepts the printed protective layer, and forms a circuit pattern after corrosion.

[0003] In the prior art, copper foil must undergo a series of tests during the production process, among which tensile testing is particularly critical. Currently, most tensile testing equipment is mainly used to test structures such as metal strips. These devices are not suitable for the special properties of copper foil. Since copper foil has extremely high ductility and flexibility, there is an urgent need for a specially designed testing device to ensure that its tensile performance meets standard requirements. In addition, such a device should minimize manual intervention during the testing process to improve efficiency and accuracy. To this end, the present invention provides a fixing device for copper foil tensile testing. Summary of the Invention

[0004] The object of the present invention is to provide a fixing device for copper foil tensile testing to solve the problems raised in the above background technology.

[0005] The technical solution of the present invention is: a fixing device for copper foil tension detection, comprising a mounting base, the top of the mounting base is fixedly connected to a fixed side box, one side of the fixed side box is fixedly connected to a detection telescopic cylinder, the output end of the detection telescopic cylinder is fixedly connected to a detection pull box, one side of the detection pull box is fixedly connected to two fixed guide plates, the inner sides of the two fixed guide plates are slidably connected to a fixed mounting block, one side of the fixed mounting block is highly connected to two mounting side plates, the inner sides of the two mounting side plates are fixedly connected to two pressing inner shafts, the outer sides of the pressing inner shafts are rotatably connected to a pressing The rotating plate, a torsion spring is installed between the pressing rotating plate and the pressing inner shaft, the torsion spring is movably sleeved on the outer side of the pressing inner shaft, and the adjacent sides of the two pressing rotating plates are movably connected with a buffer bottom block, the top of the buffer bottom block is fixedly connected with a fixed pressure pad, and the bottom of the buffer bottom block is fixedly connected with a buffer spring, and the buffer spring is installed inside the pressing rotating plate, and the inner side of the detection pull box is slidingly connected with two fixed pull rods, the top of the fixed pull rod is fixedly connected to the fixed mounting block, and the fixed pull rod is rotatably connected to a fixed limit block at one end away from the fixed mounting block, and the fixed limit block slides The cam is connected to the inner side of the detection pull box, and a fixed limiting groove is opened on one side of the detection pull box. The top of the mounting base is fixedly connected to a fixed outer frame. The inner side of the fixed outer frame is fixedly connected to two guide outer plates, and the guide outer plates are the same as the inner grooves of the fixed guide plates. When in use: the fixed mounting block is slidably engaged with the inner sides of the two fixed guide plates. Initially, the fixed mounting block is pushed to the inner sides of the guide outer plates by the fixed pull rod, so that the pressing rotating plate is separated from the guide outer plates. After that, the pressing rotating plate is twisted by the torsion spring, so that the two pressing rotating plates are unfolded, and the copper foil to be inspected is placed on the two pressing rotating plates. The copper foil is clamped between the plates, and then the fixed pull rod is pulled to make the pressing rotary plate slide to the inner side of the guide outer plate, so that the two pressing rotary plates clamp the copper foil, and the two fixed pressure pads squeeze the fixed copper foil against each other, and the length of the pressing rotary plate is greater than the extrusion bottom block. When the pressing rotary plate passes through the extrusion bottom block, it will not unfold. After the fixed pull rod passes through the detection pull box, the fixed limit block is rotated to make the fixed limit block clamped in the inside of the fixed limit groove. When performing tension testing, the telescopic cylinder is tested to extend and retract, and the detection pull box is pulled. The fixed limit block is driven by the detection pull box, which drives the fixed pull rod and the fixed mounting block, thereby pulling the copper foil for testing.

[0006] The top of the two fixed guide plates is fixedly connected to the guide plate, and the outer ends of the two fixed guide plates are fixedly connected to the guide plate. The interior of the guide pull frame is provided with two opposite guide bevels, the guide pull frame is slidably engaged with the inner side of the fixed outer frame, and the two ends of the pressing fixed shaft are slidably engaged with the interior of the guide bevels; when in use: when performing inspection, the fixed guide plate will pull the fixed guide plate to move, and pull the guide pull frame to move, so that the two pressing fixed shafts slide along the guide bevels, so that the two pressing fixed shafts approach each other, so that the extrusion bottom block and the extrusion top block are tightly attached. Because the pressing fixed roller is connected by a one-way bearing, the copper foil does not rotate when pulling the pressing fixed roller, so that the two pressing fixed rollers fix the other end of the extruded copper foil, thereby completing the inspection. After the inspection is completed, the pressing fixed shafts are separated by resetting the guide bevels, and the inspected copper foil is taken out.

[0007] The present invention provides a fixing device for copper foil tensile testing through improvement, which has the following improvements and advantages compared with the prior art:

[0008] When the two guide plates are pressed together, the two guide plates are pressed together, and the two guide plates are pressed together, so that the two guide plates are pressed together.

[0009] Second, the present invention discloses a fixing device for copper foil tension testing. When testing, the fixed guide plate pulls the fixed guide plate to move, which in turn pulls the guide frame to move, causing the two pressing fixed shafts to slide along the guide chute, bringing the two pressing fixed shafts closer to each other and making the extrusion bottom block and the extrusion top block close to each other. Because the pressing fixed rollers are connected by one-way bearings, the copper foil does not rotate when pulling the pressing fixed rollers, so that the two pressing fixed rollers fix and extrude the other end of the copper foil, thereby completing the test. After the test is completed, the guide chute is reset to separate the pressing fixed shafts, and the tested copper foil is removed.

[0010] Summary: The fixing device for copper foil tensile testing described in the present invention has the characteristics of compact structure, simple operation, high detection efficiency and good accuracy. Through the implementation of the above technical solution, the copper foil does not need to be straightened and fixed manually, which can effectively reduce manual intervention, avoid detection errors caused by improper operation, and ensure the stability and repeatability of copper foil tensile testing.

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] The present invention provides a fixing device for copper foil tensile testing through improvement. The technical solution of the present invention is:

[0023] like Figure 1-Figure 7As shown, a fixing device for copper foil tension detection includes a mounting base 1, the top of the mounting base 1 is fixedly connected to a fixed side box 2, one side of the fixed side box 2 is fixedly connected to a detection telescopic cylinder 4, the output end of the detection telescopic cylinder 4 is fixedly connected to a detection pull box 5, one side of the detection pull box 5 is fixedly connected to two fixed guide plates 6, the inner sides of the two fixed guide plates 6 are slidably connected to a fixed mounting block 9, one side of the fixed mounting block 9 is highly connected to two mounting side plates 13, the inner sides of the two mounting side plates 13 are fixedly connected to two pressing inner shafts 14, the outer sides of the pressing inner shafts 14 are rotatably connected to a pressing rotating plate 15, and the pressing rotating plate 15 and the pressing inner shaft 14 are connected to each other. A torsion spring 16 is installed between the two pressing plates 15, and the torsion spring 16 is movably sleeved on the outside of the pressing inner shaft 14. The two pressing rotating plates 15 are movably connected to a buffer bottom block 17 on one adjacent side. The top of the buffer bottom block 17 is fixedly connected to a fixed pressure pad 19, and the bottom of the buffer bottom block 17 is fixedly connected to a buffer spring 18. The buffer spring 18 is installed inside the pressing rotating plate 15. The inner side of the detection pull box 5 is slidably connected to two fixed pull rods 10. The top of the fixed pull rod 10 is fixedly connected to the fixed mounting block 9. The end of the fixed pull rod 10 away from the fixed mounting block 9 is rotatably connected to a fixed limit block 11. The fixed limit block 11 is slidably connected to the inner side of the detection pull box 5. A fixed limiting groove 12 is provided on one side of the box 5, and the top of the mounting base 1 is fixedly connected to the fixed outer frame 3, and the inner side of the fixed outer frame 3 is fixedly connected to two guide outer plates 8, and the guide outer plates 8 have the same inner groove as the fixed guide plates 6; when in use: the fixed mounting block 9 is slidably engaged with the inner side of the two fixed guide plates 6, and initially, the fixed mounting block 9 is pushed to the inner side of the guide outer plates 8 by the fixed pull rod 10, so that the pressing turn plate 15 is disengaged from the guide outer plate 8, and then the pressing turn plate 15 is twisted by the torsion spring 16, so that the two pressing turn plates 15 are unfolded, and the copper foil to be tested is placed between the two pressing turn plates 15, and then the fixed pull rod 10 is pulled , so that the pressing turn plate 15 slides to the inner side of the guide outer plate 8, so that the two pressing turn plates 15 clamp the copper foil, and the two fixed pressure pads 19 squeeze the fixed copper foil against each other, and the length of the pressing turn plate 15 is greater than the extrusion bottom block 23. When the pressing turn plate 15 passes through the extrusion bottom block 23, it will not unfold. After the fixed pull rod 10 passes through the detection pull box 5, the fixed limit block 11 is rotated to make the fixed limit block 11 clamped in the inside of the fixed limit groove 12. When performing tension testing, the telescopic cylinder 4 is detected to be extended and retracted, pulling the detection pull box 5, and the fixed limit block 11 is driven by the detection pull box 5, which drives the fixed pull rod 10 and the fixed mounting block 9, thereby pulling the copper foil for testing.

[0024] Furthermore, the bottom inner wall of the fixed outer frame 3 is slidably connected with two extruded bottom columns 22, the top of the extruded bottom column 22 is fixedly connected with an extruded bottom block 23, and a pressing fixed shaft 24 is fixedly connected between the two extruded bottom blocks 23. The top inner wall of the fixed outer frame 3 is slidably connected with two extruded top columns 20, the bottom of the extruded top column 20 is fixedly connected with an extruded top block 21, and a pressing fixed shaft 24 is fixedly connected between the two extruded top blocks 21. The outer one-way bearing of the pressing fixed shaft 24 is connected with a pressing fixed roller 25. The inclined surface at the top of the extruded bottom block 23 has the same angle as the bottom inclined surface of the extruded top block 21 and fits each other. The extruded top block 21 and the extruded bottom block 23 are movably connected between the fixed guide plate 6 and the guide outer plate 8. The outer sides of the two fixed guide plates 6 are fixedly connected with the guide pull frame 7. Two opposite guide bevels 26 are provided inside the pull frame 7, and the guide pull frame 7 is slidably engaged with the inner side of the fixed outer frame 3, and the two ends of the pressing fixed shaft 24 are slidably engaged with the inside of the guide bevels 26; when in use: when testing, the fixed guide plate 6 will pull the fixed guide plate 6 to move, and pull the guide pull frame 7 to move, so that the two pressing fixed shafts 24 slide along the guide bevels 26, so that the two pressing fixed shafts 24 are close to each other, so that the extrusion bottom block 23 is in close contact with the extrusion top block 21. Because the pressing fixed roller 25 is connected by a one-way bearing, the copper foil does not rotate when pulling the pressing fixed roller 25, so that the two pressing fixed rollers 25 fix the other end of the extruded copper foil, thereby completing the test. After the test is completed, the pressing fixed shafts 24 are separated by resetting through the guide bevel 26, and the tested copper foil is taken out.

[0025] Working principle: When in use: the fixed mounting block 9 is slidably engaged with the inner side of the two fixed guide plates 6. Initially, the fixed mounting block 9 is pushed to the inner side of the guide outer plate 8 by the fixed pull rod 10, so that the pressing turn plate 15 is separated from the guide outer plate 8. Then, the pressing turn plate 15 is twisted by the torsion spring 16, so that the two pressing turn plates 15 are unfolded, and the copper foil to be inspected is placed between the two pressing turn plates 15. Then, the fixed pull rod 10 is pulled to slide the pressing turn plate 15 to the inner side of the guide outer plate 8, so that the two pressing turn plates 15 clamp the copper foil, so that the two fixed pressure pads 19 squeeze the fixed copper foil against each other, and the length of the pressing turn plate 15 is greater than the extrusion bottom block 23. When the pressing turn plate 15 passes through the extrusion bottom block 23, it will not unfold.

Connected to the inside of the fixed limit groove 12, when performing tension detection, the detection telescopic cylinder 4 is extended and retracted, pulling the detection pull box 5, and the fixed limit block 11 is driven by the detection pull box 5, driving the fixed pull rod 10, and driving the fixed mounting block 9, thereby pulling the copper foil for detection. When the detection is performed, the fixed guide plate 6 will pull the fixed guide plate 6 to move, and pull the guide pull frame 7 to move, so that the two pressing fixed shafts 24 slide along the guide inclined groove 26, so that the two pressing fixed shafts 24 are close to each other, so that the extrusion bottom block 23 is close to the extrusion top block 21. Because the pressing fixed roller 25 is connected by a one-way bearing, the copper foil does not rotate when pulling the pressing fixed roller 25, so that the two pressing fixed rollers 25 fix the other end of the extruded copper foil, thereby completing the detection. When the detection is completed, the pressing fixed shaft 24 is reset through the guide inclined groove 26 to separate the testing copper foil, and the detection copper foil is taken out.
