[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] To address the technical problem in existing technologies where the moving and fixed clamping plates interfere with the operator's hands when placing copper foil in the gap between them, making copper foil placement inconvenient, this invention provides a strip copper foil tensile testing machine. This machine allows the operator's hands to enter the clearance groove, avoiding interference with the base and improving the convenience of copper foil placement. Furthermore, it features a simple structure and saves costs.

[0037] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the structure of a strip copper foil tensile testing machine according to an embodiment of the present invention. The strip copper foil tensile testing machine includes a frame 1, two sets of seats 2, two sets of clamping seats 3, and two sets of driving units 4. The two sets of seats 2 are mounted on the frame 1, and the distance between them is adjustable. Each seat 2 has a clearance groove 2a with one open side. The two sets of clamping seats 3 are respectively mounted on the two sets of seats 2 and can form a clamping gap 3a with the adjacent seat 2 at intervals. The clamping gap 3a has a connecting port 3b on the open side 2b of the clearance groove. The two sets of driving units 4 are respectively drivenly connected to the two sets of clamping seats 3, and are used to drive the connected clamping seats 3 to move closer to and away from the adjacent seat 2. Specifically, each clamping seat 3 can move closer to and away from the adjacent seat 2, and when moving away from the adjacent seat 2, it forms a clamping gap 3a with the seat 2 at intervals.

[0038] In the strip copper foil tensile testing machine provided by this utility model, the testing personnel hold the copper foil and feed it into the clamping gap 3a through the connecting port 3b. Since the connecting port 3b and the open side 2b of the relief groove are located on the same side of the base 2, the testing personnel's hand can enter the relief groove 2a, avoiding interference with the base 2, improving the convenience of copper foil placement, and the structure is simple and cost-effective. After the copper foil is placed, the distance between the two bases 2 can be adjusted to stretch the copper foil, thus realizing the copper foil tensile test.

[0039] In one embodiment, the base 2 is connected to a mounting base 5 on the side of the clearance groove 2a near the other base 2. The mounting base 5 is provided with a mounting channel 5a along the direction near the other base 2. The end of the mounting channel 5a near the clearance groove 2a is provided with a material passage 5b, which communicates with the clearance groove 2a. The clamping base 3 is installed in the mounting channel 5a, and the communication port 3b and the material passage 5b are located on the two adjacent sides of the mounting channel 5a.

[0040] In this embodiment, the connecting port 3b of the installation channel 5a is connected to the clearance groove 2a, that is, the end of the clamping gap 3a near the clearance groove 2a is connected to the clearance groove 2a, so that when one end of the copper foil is clamped in the clamping gap 3a, it can extend into the clearance groove 2a from the connecting port 3b. This improves the stability of clamping the copper foil on the one hand, and improves the convenience for the testing personnel to place the copper foil on the other hand.

[0041] It should be noted that there are no restrictions on the form of the driving component. It can be set as a linear motor or a hydraulic rod, as long as it can drive the clamping seat 3 to move closer to and away from the seat 2.

[0042] In one embodiment, please refer to Figure 3 and Figure 4 The mounting base 5 is provided with a drive screw hole 5c, which extends in the direction close to the base body 2 and connects to the mounting channel 5a; the drive part 4 includes a drive screw 41, one end of which is screwed into the drive screw hole 5c and extends into the mounting channel 5a and is connected to the clamping seat 3, for driving the clamping seat 3 to approach and move away from the base body 2.

[0043] In this embodiment, the clamping seat 3 is moved closer to and away from the seat 2 by rotating the drive screw 41, thus achieving the clamping and release of the copper foil. The operation is simple and convenient. Specifically, in one embodiment, a flexible pad is provided on the side of the clamping seat 3 near the seat 2 to avoid damaging the copper foil. The flexible pad can be a rubber pad or a silicone pad.

[0044] In one embodiment, one of the clamping seat 3 and the inner wall of the mounting channel 5a is provided with a slider, and the other is provided with a slide groove for mounting the slider, the slide groove extending in the direction close to the seat body 2; the drive screw 41 is rotatably connected to the clamping seat 3.

[0045] In this embodiment, a slider and a groove are arranged in the inner wall of the clamping seat 3 and the mounting channel 5a as described above, and the drive screw 41 is rotatably connected to the clamping seat 3 to prevent the clamping seat 3 from rotating synchronously when the drive screw 41 rotates, so that the clamping seat 3 can maintain linear motion and avoid the clamping seat 3 from wrinkling the copper foil due to rotation. Specifically, in this solution, the groove 5d is provided on the inner wall of the mounting channel 5a, and the slider 31 is provided on the clamping seat 3.

[0046] In one embodiment, the strip copper foil tensile testing machine further includes a tensile mechanism 6, which is disposed on the frame 1 and drivenly connected to at least one body 2 for driving the body 2 to move closer to and away from another body 2.

[0047] In this embodiment, the tension mechanism 6 drives the seat 2 to move, thereby adjusting the distance between the two seat 2s to achieve tension detection. Specifically, the corresponding tensile force can be calibrated by the distance between the two seat 2s for direct reading.

[0048] It should be noted that, in one embodiment, the tension mechanism 6 is configured as a winch rope and a winch motor, so as to drive the seat 2 to move by winding the winch rope; while in another embodiment, the tension mechanism 6 can be configured as a hydraulic rod or a linear motor.

[0049] In one embodiment, please refer to Figure 5 The frame 1 is provided with a guide channel 1a in the vertical direction; the tension mechanism 6 includes a tension seat 61, a tension screw 62 and a tension motor 63. The tension seat 61 is slidably disposed in the guide channel 1a in the vertical direction and is provided with a tension screw hole in the vertical direction. The tension screw 62 is screwed into the tension screw hole. The tension motor 63 is installed on the frame 1 and connected to the tension screw 62. One of the two seats 2 is installed on the tension seat 61 and the other is installed on the frame 1.

[0050] In this embodiment, the tension motor 63 rotates, thereby driving the tension screw 62 to rotate, which in turn drives the tension seat 61 to move in the vertical direction to adjust the distance between the two seats 2. The tension adjustment accuracy is high, and the structure is stable and reliable.

[0051] In one embodiment, the two bases 2 are detachably connected to the frame 1.

[0052] In this embodiment, the base 2 is detachably connected to the frame 1 to facilitate flexible replacement of the base 2 and the clamping seat 3 on it. Specifically, the base 2 and the frame 1 can be detachably connected by bolts, or by electromagnetic adsorption, or by other means.

[0053] In one embodiment, the base 2 is connected to a connecting arm 21, and the connecting arm 21 is provided with a mating hole 21a; the strip copper foil tensile testing machine also includes two bases 7 and two limiting arms 8. The two bases 7 are respectively installed on the frame 1, and are provided with insertion holes 7a in the direction away from the other base 7. The insertion holes 7a are provided with limiting holes 7b in their radial direction; wherein, the two connecting arms 21 are respectively inserted into the two insertion holes 7a, and the two limiting arms 8 are respectively passed through the two sets of limiting holes 7b and mating holes 21a.

[0054] In this embodiment, when installing the base 5 body 2, the connecting arm 21 on the base 2 is inserted into the corresponding insertion hole 7a, and the mating hole 21a on the connecting arm 21 is aligned with the limiting hole 7b of the base 7. Then, the limiting arm 8 is inserted into the limiting hole 7b and the mating hole 21a to realize the installation of the base 2. When disassembly is required, the limiting arm 8 can be pulled out, which is simple and convenient to operate.

[0055] In one embodiment, multiple limiting holes 7b are provided at circumferential intervals along the base 7.

[0056] In this embodiment, multiple limiting holes 7b are spaced apart along the circumference of the base 7, so that the mating hole 21a can be aligned with any of the limiting holes 7b, thereby allowing for flexible adjustment of the orientation of the base 2 during installation and improving practicality. Specifically, in this solution, two limiting holes 7b are provided. One end of the limiting arm 8 is also tapered to facilitate the passage of the limiting hole 7b and the mating hole 21a.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0058] The workflow of the strip copper foil tensile testing machine in this solution is as follows:

[0059] The inspector holds the copper foil and feeds it into the clamping gap 3a through the connecting port 3b. Since the connecting port 3b and the open side 2b of the relief groove are located on the same side of the base 2, the inspector's hand can enter the relief groove 2a, and the end of the copper foil can be inserted into the relief groove 2a through the feed port 5b, ensuring that the clamping base 3 effectively clamps the copper foil. Furthermore, during the placement of the copper foil, the relief groove 2a prevents interference between the inspector's hand and the base 2, improving the convenience of copper foil placement.

[0060] After the copper foil is placed, the tension motor 63 can drive the tension screw 62 to rotate, which in turn drives the tension seat 61 to move in the vertical direction, so as to adjust the distance between the two seats 2 to stretch the copper foil and realize the copper foil tension detection.

[0061] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
