Description

An auxiliary device for stable detection of tensile strength elongation Technical Field

[0001] This utility model relates to the field of electrolytic copper foil production and testing technology, and in particular to an auxiliary device for stable testing of tensile strength elongation. Background Technology

[0002] Electrolytic copper foil serves as both a carrier of the negative electrode active material and a collector and transporter of electrons in lithium-ion batteries, making it a crucial material. Battery manufacturers impose specific requirements on the intrinsic properties of copper foil, and its internal indicators significantly impact the manufacturing process of the lithium-ion battery negative electrode and the electrochemical performance of the battery itself. Instability can occur during the post-production testing of electrolytic copper foil, making stability testing a critical step in the overall testing process.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Currently, in the process of testing copper foil, most tests use tensile testing machines of different models. However, during the testing of copper foil, prolonged use can lead to invisible wear and unevenness on the surface, resulting in data fluctuations or abnormally low indicators, making it difficult to meet normal testing and technical reference requirements. Therefore, those skilled in the art have provided an auxiliary device for stably testing tensile strength elongation to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for stable detection of tensile strength elongation. By setting a clamping mechanism on the lower end face of the adjustment frame, the adjustment block and clamping block in the clamping mechanism can be engaged and fitted together. A kraft paper layer is pasted on one side surface of the clamping block, which can effectively eliminate the micro-deformation of the interface through the kraft paper layer. At the same time, the setting can also better fix and detect the copper foil by the clamping mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An auxiliary device for stable testing of tensile strength elongation includes a base and two adjusting frames. A fixing frame is fixedly installed on the upper surface of the base. A first bidirectional screw is rotatably embedded in both sides of the lower surface of the fixing frame near the front end. A second bevel gear is fixedly installed at one end of each of the two first bidirectional screws that passes through the upper surface of the fixing frame. A sliding rod is fixedly installed in both sides of the lower surface of the fixing frame near the rear end. An adjusting groove is opened on the lower surface of each of the two adjusting frames, and a second bidirectional screw is rotatably embedded in each of the two adjusting grooves.

[0007] Both sides of the lower end face of the two adjustment frames are provided with clamping mechanisms, and each of the four clamping mechanisms includes a clamping rod. An adjustment block is movably embedded on the upper side of each of the four clamping rods. A clamping block is snapped into one side of each of the four adjustment blocks, and a kraft paper layer is provided on one side of each of the four clamping blocks.

[0008] Furthermore, a threaded rod is rotatably embedded at the midpoint of the upper end of one side of each of the four clamping rods, and one end of each of the four adjusting blocks is threaded onto the outer surface of the four threaded rods.

[0009] Furthermore, each of the four adjusting blocks has a slot on one side, and the four clamping blocks are snapped into the slot on one side. The lower ends of the four clamping rods are threaded onto both sides of the outer surface of the two second bidirectional screws.

[0010] Furthermore, the kraft paper layer is made of silicone oil-impregnated adhesive industrial kraft paper, and the size of the kraft paper layer is the same as the size of the effective contact area of ​​the sandwich panel.

[0011] Furthermore, adjustment plates are fixedly installed on both sides of the lower end face of the two adjustment frames, and the two adjustment plates are respectively sleeved on the outer surfaces of the two slide rods and the two first bidirectional screws near the front and rear ends.

[0012] Furthermore, a dual-axis servo motor is snapped onto the upper end face of the fixed frame near the midpoint of the rear end. Both output ends of the dual-axis servo motor are fixedly equipped with transmission shafts. One end of each of the two transmission shafts is fixedly equipped with a first bevel gear, and the two first bevel gears are respectively meshed with two second bevel gears.

[0013] Furthermore, a base plate is fixedly installed on both sides of the lower end face of the base, and a protective shell is snapped onto the upper end face of the fixing frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. The auxiliary device for stable detection of tensile strength elongation proposed in this utility model, after opening an adjustment groove on the lower end face of the adjustment frame, can rotate and embed a second bidirectional screw in the adjustment groove. After the clamping mechanism is sleeved on the outer surface of the second bidirectional screw, the second bidirectional screw can drive the clamping mechanism to move in opposite directions, so that the clamping block can clamp and fix the copper foil. At the same time, the adjustment block that is movably embedded in the clamping mechanism can be moved and adjusted by the threaded rod, so that after the clamping mechanism clamps and fixes the copper foil, it can further clamp and fix the copper foil.

[0016] 2. The auxiliary device for stable testing of tensile strength elongation proposed in this utility model, by opening a slot on one side of the adjusting block in the clamping mechanism, can snap-fit ​​the clamping block into the adjusting block. One side of the clamping block is pasted with a kraft paper layer. When clamping and fixing the copper foil, the clamping block with a kraft paper layer on one side can effectively eliminate the micro-deformation of the interface and reduce the fluctuation range of the copper foil tensile strength test. At the same time, the pasted kraft paper layer can be easily replaced or installed, thereby effectively reducing the impact on the copper foil during tensile testing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Referring to Figures 1 to 5, an auxiliary device for stable detection of tensile strength elongation includes a base 4 and two adjusting frames 6. A fixing frame 2 is fixedly installed on the upper end surface of the base 4. A first bidirectional screw 7 is rotatably embedded in both sides of the lower end surface of the fixing frame 2 near the front end. A second bevel gear 17 is fixedly installed at one end of each of the two first bidirectional screws 7 that passes through the upper end surface of the fixing frame 2. A sliding rod 3 is fixedly installed in both sides of the lower end surface of the fixing frame 2 near the rear end. An adjusting groove 12 is opened on the lower end surface of each of the two adjusting frames 6. A second bidirectional screw 13 is rotatably embedded in each of the two adjusting grooves 12.

[0026] Both sides of the lower end face of the two adjustment frames 6 are provided with clamping mechanisms 8. Each of the four clamping mechanisms 8 includes a clamping rod 802. An adjustment block 803 is movably embedded on the upper side of each of the four clamping rods 802. A clamping block 11 is snapped into one side of each of the four adjustment blocks 803. A kraft paper layer 10 is provided on one side of each of the four clamping blocks 11.

[0027] Specifically, after fixing the fixing frame 2 to the upper end face of the base 4, two sliding rods 3 and two first bidirectional screws 7 can be set between the upper end face of the base 4 and the lower end face of the fixing frame 2. After fixing the adjusting frame 6 with the adjusting plate 5 to the upper and lower ends of the outer surface of the two sliding rods 3 and the two first bidirectional screws 7, the rotating first bidirectional screws 7 can drive the two adjusting frames 6 to move up and down synchronously, so as to better perform tensile tests on the clamped copper foil. After setting the clamping mechanism 8 on both sides of the lower end face of the adjusting frame 6, the second bidirectional screw 13 embedded in the adjusting frame 6 can drive the clamping mechanism 8 to move in position, so that the copper foil can be clamped and fixed by the clamping block 11 snapped in the clamping rod 802. After pasting the kraft paper layer 10 on one side of the clamping block 11, the interface micro-deformation caused by clamping and fixing the copper foil can be eliminated.

[0028] Referring to Figure 5, threaded rods 801 are rotatably embedded at the midpoint of the upper end of one side of the four clamping rods 802, and one end of each of the four adjusting blocks 803 is threaded onto the outer surface of the four threaded rods 801.

[0029] Specifically, after the threaded rod 801 is inserted into the upper side of the clamping rod 802, the adjusting block 803 can be threaded onto the outer surface of the threaded rod 801. After rotating the threaded rod 801, the adjusting block 803 can be moved to a different position. The moved adjusting block 803 can better drive the clamping block 11 to clamp and fix the copper foil.

[0030] Referring to Figures 3 and 5, each of the four adjusting blocks 803 has a slot 804 on one side, and the four clamping blocks 11 are snapped into the slot 804 on one side. The lower ends of the four clamping rods 802 are threaded onto the outer surfaces of the two second bidirectional screws 13.

[0031] Specifically, after a slot 804 is opened on one side of the adjusting block 803, the clamping block 11 can be movably engaged in the slot 804, so that the adjusting block 803 can drive the clamping block 11 to move in position. After the clamping rod 802 is threaded onto the outer surface of the second bidirectional screw 13, the second bidirectional screw 13 can be rotated to drive the clamping mechanism 8 to move in position.

[0032] Referring to Figure 3, the kraft paper layer 10 is made of silicone oil-impregnated adhesive industrial kraft paper, and the size of the kraft paper layer 10 is the same as the size of the effective contact area of ​​the sandwich block 11.

[0033] Specifically, the kraft paper layer 10, made of silicone oil-impregnated adhesive industrial kraft paper, has both abrasion resistance and tear resistance. After the size of the kraft paper layer 10 is cut to be the same as the size of the effective clamping contact area of ​​the clamping block 11, the kraft paper layer 10 can be pasted to one side of the clamping block 11. After pasting the kraft paper layer 10 to one side of the clamping block 11, air bubbles can be removed by pressing the kraft paper layer 10 with the fingertips, so that the kraft paper layer 10 and the clamping block 11 can be better bonded.

[0034] Referring to Figures 1 and 3, adjustment plates 5 are fixedly installed on both sides of the lower end face of the two adjustment frames 6. The two adjustment plates 5 are respectively sleeved on the outer surfaces of the two slide rods 3 and the two first bidirectional screws 7 near the front and rear ends.

[0035] Specifically, after the adjustment plates 5 are fixedly installed on both sides of the lower end face of the adjustment frame 6, the adjustment frame 6 can be better fitted onto the outer surfaces of the two slide rods 3 and the two first bidirectional screws 7. When the first bidirectional screws 7 are rotated, they can drive the adjustment frame 6 to move up and down, so that the copper foil clamped and fixed between the clamping mechanisms 8 can be subjected to tensile testing.

[0036] Referring to Figure 4, a dual-axis servo motor 15 is snapped onto the upper end face of the fixed frame 2 near the midpoint of the rear end. Both output ends of the dual-axis servo motor 15 are fixedly equipped with drive shafts 14. One end of each drive shaft 14 is fixedly equipped with a first bevel gear 16. The two first bevel gears 16 are respectively meshed with two second bevel gears 17.

[0037] Specifically, after the dual-axis servo motor 15 is snapped onto the upper end face of the fixed frame 2, the transmission shaft 14, on which the first bevel gear 16 is fixed, can be fixed onto the output ends of the dual-axis servo motor 15 on both sides. After the second bevel gear 17 is fixed onto the upper end face of the two first bidirectional screws 7 that penetrate the upper end face of the fixed frame 2, the two first bevel gears 16 and the two second bevel gears 17 can be meshed and connected. After the connection is completed, the dual-axis servo motor 15 can better drive the two first bidirectional screws 7 to rotate synchronously.

[0038] Referring to Figures 1 and 2, base plates 9 are fixedly installed on both sides of the lower end face of the base 4, and a protective shell 1 is snapped onto the upper end face of the fixing frame 2.

[0039] Specifically, after the base plate 9 is fixedly installed on both sides of the lower end face of the base 4, the stability of the equipment can be improved. After the protective shell 1 is snapped onto the upper end face of the fixed frame 2, it can be sleeved on the outer surface of the dual-axis servo motor 15, the first bevel gear 16 and the second bevel gear 17, thereby providing a certain degree of protection for the dual-axis servo motor 15.

[0040] Working principle: In use, the user can cut the kraft paper layer 10 to the same size as one side of the clamping block 11. After attaching the kraft paper layer 10 to one side of the clamping block 11, the user can press with their fingertips to remove air bubbles from the kraft paper layer 10. After pasting, the clamping block 11 can be snapped into the clamping mechanism 8. Rotating the second bidirectional screw 13 in the adjusting frame 6 can move and adjust the clamping mechanism 8. After placing the copper foil between the four clamping mechanisms 8, the clamping mechanism 8 can move the clamping block 11 to clamp and fix the copper foil. Rotating the threaded rod 801 can move the clamping block 11 to assist in clamping the copper foil. After the copper foil is fixed, the dual-axis servo motor 15 can be started to drive the two first bidirectional screws 7 to rotate. The rotating first bidirectional screws 7 can move and adjust the adjusting frame 6 at the upper and lower ends, so that the tensile strength test can be performed on the clamped and fixed copper foil.
