[0002] During the formation and shipping processes of polymer batteries, the width of both sides of the battery needs to be measured. Operators currently hold the battery with their left hand and use calipers in their right hand to measure both sides. However, due to increasingly stringent industry quality requirements, the current measurement technology suffers from low accuracy and uncontrollable measurement pressure, leading to poor stability. Furthermore, human contact with the battery can easily cause appearance defects. Manually measuring the battery width with calipers is no longer sufficient to meet process requirements. Therefore, designing a precision width measuring instrument for polymer lithium batteries to replace manual cell measurement is a key technical challenge in equipment automation.

[0003] This invention primarily addresses the problems of low accuracy in measuring the width of polymer batteries and the inability to adjust the pressure. Utility Model Content

One side of the movable measuring block is connected to the digital caliper, and the movable measuring block is movably arranged. The pulling component provides a force that moves the movable measuring block toward the fixed measuring block. The pushing component is mounted on the measuring platform and is used to push the movable measuring block away from the fixed measuring block.

[0007] Specifically, the adjustment assembly includes an adjustment backplate and at least two adjustment members. The adjustment backplate is mounted on the measurement platform and is arranged adjacent to the fixed measurement block. All the adjustment members are spaced apart along the length direction of the fixed measurement block. The adjustment members pass through the adjustment backplate and press against the fixed measurement block to adjust the position of the fixed measurement block by abutting it. The fixed measurement block is provided with an elliptical adjustment hole, the length direction of which is the same as the length direction of the measurement platform. The measurement platform is provided with a circular fixing hole, the length of which is greater than the diameter of which is the diameter of which is the adjustment hole. A locking member is inserted between the adjustment hole and the fixing hole to lock the displacement of the fixed measurement block relative to the longitudinal direction of the measurement platform.

[0008] Preferably, the precision width measuring instrument for polymer lithium batteries further includes a guide rail assembly for guidance, the guide rail assembly including a slider and a guide rail mounted on the measuring platform, and the movable measuring block being connected to the slider of the guide rail assembly.

[0009] Specifically, the pulling assembly includes a weight, a wire, and a guide wheel. The measuring platform is raised by a box structure, and the top surface of the box structure forms the measuring platform. The guide wheel is installed on the side of the box structure. One end of the wire is connected to the slider, and the other end of the wire is connected to the weight. The middle part of the wire is wound around the guide wheel. The weight pulls the movable measuring block on the slider toward the fixed measuring block.

[0011] Specifically, the pulling assembly further includes a wire fixing component, which includes a fixing body and connecting claws extending outward from both ends of the fixing body. The connecting claws are connected to both sides of the slider. The measuring platform has elongated clearance holes that are symmetrically arranged and parallel to the connecting claws.

[0028] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please see Figures 1 to 5A precision width measuring instrument 100 for polymer lithium batteries can be applied to semi-automatic manual feeding triggered by foot pedal start or embedded in a fully automatic production line for mechanical suction hand feeding and unloading. The precision width measuring instrument 100 for polymer lithium batteries includes a measuring platform 11, a fixed measuring block 2, a movable measuring block 4, a digital caliper 6, a pushing component 7, and a pulling component 8. The measuring platform 11 is set on a raised platform and is a horizontal platform surface that is kept at a certain distance from the ground, thereby providing vertical distance to facilitate the pulling component 8 to pull by gravity. Both the fixed measuring block 2 and the movable measuring block 4 are long strip plate structures and are made of epoxy board to avoid the risk of battery short circuit or scratch. Fixed measuring block 2 and movable measuring block 4 are sequentially arranged on measuring platform 11 along the length direction of measuring platform 11. Fixed measuring block 2 and movable measuring block 4 are parallel to each other, and a measuring gap a is formed between fixed measuring block 2 and movable measuring block 4. The measuring gap a is mainly for the object to be measured 10 to be placed. Fixed measuring block 2 and movable measuring block 4 are pressed together from both sides of the object to be measured 10 to achieve the purpose of measurement. One side of movable measuring block 4 is connected to digital caliper 6. Digital caliper 6 is a precision digital horizontal caliper. The movable measuring block 4 is movably positioned and moves towards or away from the fixed measuring block 2. The pulling component 8 provides a force that moves the movable measuring block 4 towards the fixed measuring block 2. The pushing component 7, mounted on the measuring platform 11, pushes the movable measuring block 4 away from the fixed measuring block 2. During measurement, the pushing component 7 pushes the movable measuring block 4 away from the fixed measuring block 2, increasing the measuring gap a to allow the object to be measured to be placed in and maintaining a distance between the object and the fixed measuring block 2. When measurement is needed, the pushing component 7 retracts, maintaining a distance between itself and the object. The movable measuring block 4 moves towards the fixed measuring block 2 under the pull of the pulling component 8, causing both the movable measuring block 4 and the fixed measuring block 2 to clamp the workpiece. At this point, the width of the object can be obtained by reading the digital caliper 6. This method can replace manual measurement of the battery cell, improving measurement accuracy and offering great convenience. More specifically, as follows: Please see Figure 2 as well as Figure 5The precision width measuring instrument 100 for polymer lithium batteries also includes an adjustment assembly 9 for adjusting the parallelism of the fixed measuring block 2. For example, the adjustment assembly 9 includes an adjustment back plate 91 and at least two adjustment members 92. The adjustment back plate 91 is mounted on the measuring platform 11 and is arranged adjacent to the fixed measuring block 2. All adjustment members 92 are spaced apart along the length direction of the fixed measuring block 2. The adjustment members 92 pass through the adjustment back plate 91 and press against the fixed measuring block 2 to adjust the position of the fixed measuring block 2 by abutting. The fixed measuring block 2 has an elliptical adjustment hole 21, the length direction of which is the same as the length direction of the measuring platform 11. The measuring platform 11 has a circular fixing hole 1. 11. The length of the adjustment hole 21 is greater than the diameter of the fixed hole 111. The locking member 3 is inserted between the adjustment hole 21 and the fixed hole 111 to lock the displacement of the fixed measuring block 2 relative to the measuring platform 11 in the longitudinal direction. In other words, since the adjustment hole 21 has room for adjustment, the fixed measuring block 2 can be moved under the abutment of the adjustment member 92 to adjust the parallelism of the fixed measuring block 2, so that the fixed measuring block 2 and the movable measuring block 4 remain parallel. In this way, after pressing the object to be measured 10, there is no gap between the two sides and the object to be measured 10, so as to improve the measurement accuracy.

[0030] Please see Figure 3 The precision width measuring instrument 100 for polymer lithium batteries also includes a guide rail assembly 5 for guidance. The guide rail assembly 5 includes a slider 51 and a guide rail 52 mounted on the measuring platform 11. The movable measuring block 4 is connected to the slider 51 of the guide rail assembly 5. The guide rail assembly 5 is used to ensure the linear accuracy of the movement of the movable measuring block 4.

[0031] Please see Figure 2 The pulling component 8 includes a weight 81, a wire 82, and a guide wheel 83. The measuring platform 11 is raised by the box structure 1, and the top surface of the box structure 1 forms the measuring platform 11. The guide wheel 83 is installed on the side of the box structure 1 and the left side of the box structure 1. One end of the wire 82 is connected to the slider 51, and the other end of the wire 82 is connected to the weight 81. The box structure 1 is provided with a clearance hole 1a corresponding to the wire 82. The middle part of the wire 82 is wound around the guide wheel 83. The weight 81 pulls the movable measuring block 4 on the slider 51 to move towards the fixed measuring block 2.

[0032] Please see Figure 2 The pulling component 8 also includes a weight carrying component 84, which includes a support platform 841 and a side guide rail assembly 584.

The horizontal plate 8411 and the vertical plate 8412 are perpendicular to each other. The horizontal plate 8411 is connected to the bottom of the weight 81, and the vertical plate 8412 is slidably connected to the side of the box structure 1 through the side guide rail assembly 584.

[0033] Please see Figure 4 The pulling component 8 also includes a wire fixing component 85, which includes a fixing body 851 and connecting claws 852 extending outward from both ends of the fixing body 851. The connecting claws 852 are connected to both sides of the slider 51. The measuring platform 11 has elongated clearance holes 112 that are symmetrically arranged and parallel to the connecting claws 852. The fixing body 851 is connected to one end of the wire 82.

One end of the threaded rod 73 is connected to the driving device 72, and the other end of the threaded rod 73 passes through the elongated hole 71a and is threadedly connected to the wing screw 74. By tightening the wing screw 74, the driving device 72 is locked in any position of the adjusting plate 71. The output end of the driving device 72 has a telescopic driving rod 721. The slider 51 extends outward to form a stop member 511. The stop member 511 is directly opposite the driving rod 721. Under the pressure of the driving rod 721, the stop member 511 moves away from the fixed measuring block 2 and drives the slider 51 and the movable measuring block 4 to move synchronously.

[0035] Please see Figures 4 to 5 The actuating assembly 7 also includes a hydraulic damper 75, which is connected to the adjusting plate 71. The hydraulic damper 75 is located on the side of the abutment 511 opposite to the driving device 72. The hydraulic damper 75 and the driving rod 721 are located on opposite sides of the abutment 511. When the driving rod 721 presses the abutment 511 against the hydraulic damper 75, the hydraulic damper 75 can provide cushioning. Preferably, the driving rod 721 is provided with a buffer rubber block 722, which provides protection by utilizing the elasticity of the buffer rubber block 722.

Place the battery in the measuring gap a of the measuring platform 11. The battery side is against the fixed measuring block 2. Tighten the wing screw 74 so that the drive rod 721 of the drive device 72 and the abutment 511 maintain a certain initial distance. At this time, lock the position of the drive device 72. The drive rod 721 pushes the abutment 511 to move away from the fixed measuring block 2 under the drive of the drive device 72 and stops under the buffer of the hydraulic buffer 75. At this time, the movable measuring block 4 maintains a distance of one centimeter from the edge of the battery 10 under the linkage movement, and the change adjustment is completed.
