Description

Technical Field

[0001] This utility model relates to the field of thickness measurement technology, specifically to a polymer lithium battery thickness measurement mechanism. Background Technology

[0002] Polymer lithium batteries are favored by the market for their high energy density and good cycle life. With the mass production and use of prismatic polymer lithium batteries, the requirements for the dimensional error of prismatic single primary cells (hereinafter referred to as batteries) are becoming more and more stringent, requiring precise measurement of the length, thickness, height and electrode height of the battery.

[0003] Traditional measuring equipment measures the battery by touching its surface with a contact gauge or by illuminating its surface with a non-contact optical or acoustic rangefinder. However, for square-shell batteries, such as square aluminum-shell lithium batteries, the surface bulges due to insufficient rigidity of the outer shell. Both methods, whether using a contact gauge or an optical or acoustic rangefinder, result in inaccurate measurements due to workpiece deformation.

[0004] Therefore, it is necessary to design a polymer lithium battery thickness measurement mechanism to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a polymer lithium battery thickness measuring mechanism to solve at least one technical problem existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A polymer lithium battery thickness measuring mechanism, comprising:

[0008] A workbench, wherein a vertical plate is fixed on the upper surface of the workbench, an adjusting rod is installed on the vertical plate, a clamping plate is installed on the adjusting rod, and a guide block is fixed on the edge of the clamping plate;

[0009] A support frame is fixed to the upper surface of the workbench. A stabilizing block is installed at the lower end of the support frame. Guide rods are installed on both sides of the stabilizing block. The guide rods are connected to the guide block. A horizontal plate is installed at the end of the support frame away from the stabilizing block.

[0010] A measuring rod is mounted on a horizontal plate. A vertical groove is provided on the measuring rod, and a return spring is installed in the vertical groove. A top plate is installed at the lower end of the measuring rod.

[0011] Preferably, the upper surface of the workbench and the lower surface of the top plate are respectively provided with a first anti-slip pad and a third anti-slip pad.

[0012] Preferably, the adjusting rod and the vertical plate are connected by a through thread, and the adjusting rod and the clamping plate are connected by a rotatable connection.

[0013] Preferably, the surface of the clamping plate is provided with a second anti-slip pad.

[0014] Preferably, the guide rod and the guide block are connected by a through-type sliding connection.

[0015] Preferably, the horizontal plate has a through hole, and the measuring rod is slidably connected to the horizontal plate through the through hole.

[0016] Preferably, the surface of the measuring rod is provided with a scale.

[0017] Preferably, the two ends of the reset spring are fixedly connected to the inner wall of the vertical groove and the upper surface of the horizontal plate, respectively.

[0018] Preferably, the top plate is located directly above the first anti-slip pad.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Rotate the adjusting rod; the adjusting rod can move on the vertical plate through the thread, thereby pushing the clamping plates to move synchronously. This helps the two clamping plates to move closer together, thus stabilizing the battery. Then press down on the measuring rod; the measuring rod can slide down on the horizontal plate through the perforation until the top plate drives the third anti-slip pad to press against the upper surface of the battery, flattening the bulge on the surface of the square aluminum-cased lithium battery. By observing the scale at the position where the surface of the measuring rod is flush with the upper surface of the horizontal plate, and subtracting the thickness of the first and third anti-slip pads, you can obtain the specific thickness of the battery.

[0030] Please see Figures 1-4 One embodiment provided by this utility model:

[0031] A polymer lithium battery thickness measuring mechanism, comprising:

[0032] The workbench 1 has a vertical plate 3 fixed on its upper surface. An adjusting rod 4 is installed on the vertical plate 3, and a clamping plate 5 is installed on the adjusting rod 4. The adjusting rod 4 and the vertical plate 3 are connected by a through thread, and the adjusting rod 4 and the clamping plate 5 are connected by a rotatable connection. When the adjusting rod 4 is turned to rotate, the adjusting rod 4 can move through the thread, and at this time the adjusting rod 4 can push the clamping plate 5 to move synchronously. A guide block 7 is fixed on the edge of the clamping plate 5, and a second anti-slip pad 6 is provided on the surface of the clamping plate 5. The guide rod 10 and the guide block 7 are connected by a through sliding connection. The cooperation between the guide rod 10 and the guide block 7 helps to limit the movement direction of the clamping plate 5 and improve the stability of the clamping plate 5 in displacement.

[0033] The upright frame 8 is fixed to the upper surface of the workbench 1. A stabilizing block 9 is installed at the lower end of the upright frame 8. Guide rods 10 are installed on both sides of the stabilizing block 9. The guide rods 10 are connected to the guide block 7. A horizontal plate 11 is installed at the end of the upright frame 8 away from the stabilizing block 9.

[0034] Measuring rod 13 is mounted on horizontal plate 11. Vertical groove 14 is provided on measuring rod 13, and return spring 15 is provided in vertical groove 14. Top plate 16 is installed at the lower end of measuring rod 13. First anti-slip pad 2 and third anti-slip pad 17 are respectively provided on the upper surface of workbench 1 and the lower surface of top plate 16. First anti-slip pad 2 and third anti-slip pad 17 can press firmly against the battery surface, flatten the bulge of battery casing, and prevent the battery casing from being scratched.

[0035] In one embodiment, a through hole 12 is provided on the horizontal plate 11, and the measuring rod 13 is slidably connected to the horizontal plate 11 through the through hole 12, which facilitates the measuring rod 13 to slide up and down on the horizontal plate 11 through the through hole 12. A scale is provided on the surface of the measuring rod 13, which makes it convenient to determine the thickness value of the battery by the position change of the scale on the surface of the measuring rod 13.

[0036] In one preferred embodiment, the two ends of the reset spring 15 are fixedly connected to the inner wall of the vertical groove 14 and the upper surface of the horizontal plate 11, respectively, which is beneficial for the reset spring 15 to push the measuring rod 13 upward to reset after it has been compressed.

[0037] In one embodiment, the top plate 16 is located directly above the first anti-slip pad 2, which helps the top plate 16 to be stably pressed against the battery surface.

[0038] The working principle of this utility model is as follows: First, the battery is placed on the first anti-slip pad 2. Then, the adjusting rod 4 is rotated. The adjusting rod 4 can move on the vertical plate 3 through the thread, thereby pushing the clamping plate 5 to move synchronously. At this time, the clamping plate 5 moves stably through the cooperation between the guide block 7 and the guide rod 10, which is conducive to the two clamping plates 5 moving closer to each other, thereby stably clamping the battery. Then, the measuring rod 13 is pressed down. The measuring rod 13 can slide down on the horizontal plate 11 through the through hole 12 until the top plate 16 drives the third anti-slip pad 17 to press against the upper surface of the battery, flattening the bulge on the surface of the square aluminum-cased lithium battery. By observing the scale at the position where the surface of the measuring rod 13 is flush with the upper surface of the horizontal plate 11, the thickness of the first anti-slip pad 2 and the third anti-slip pad 17 is subtracted to obtain the specific thickness of the battery. After the measurement is completed, the pressed measuring rod 13 is released. At this time, the reset spring 15 pushes the measuring rod 13 upward to reset, which is convenient for measuring the next battery.

[0039] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
