Description

Technical Field

[0001] This utility model mainly relates to the field of soft-pack battery production technology, specifically a tooling for measuring the thickness of soft-pack batteries. Background Technology

[0002] During the production and processing of pouch battery materials, the thickness of the materials needs to be tested. Only materials that meet the standards can proceed to the next stage of production and processing into pouch batteries.

[0003] Existing measuring fixtures require clamps to hold the materials when testing pouch battery materials. The thickness of the material is measured through the gap between the two clamping plates after clamping. Because this measurement method requires the clamps to hold the material and measure the gap, the clamps need to fit very tightly when clamping the material. Measuring by clamping can easily cause scratches and wear on the material, affecting the quality of pouch battery production. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing measuring tools measure the thickness of soft-pack batteries using a fixture. This solution solves the technical problem mentioned in the background that existing measuring tools measure the thickness of soft-pack battery materials using a clamping method, which causes scratches and wear on the material, affecting the quality of soft-pack battery production.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A fixture for measuring the thickness of a pouch battery includes a base, a support block mounted on the base, a drive assembly for driving the support block to move laterally, a probe for detecting the thickness of the pouch battery material mounted on the support block, and a contact sensor for contacting the bottom surface of the material being measured on the probe. A push assembly for driving the probe to move up and down is mounted on the support block.

[0007] Preferably, the drive assembly includes a screw that is rotatably connected to the base, a handle is sleeved on one end of the screw, and a support block is threaded onto the screw.

[0008] Preferably, the support block is equipped with a detector, the detector is equipped with a telescopic sleeve, the lower end of the telescopic sleeve is equipped with a probe, and the probe is equipped with a contact sensor.

[0009] Preferably, the support block is provided with a support base, the support base is located directly below the detector, and the probe is pressed down on the support base.

[0010] Preferably, a limiting block is provided on the telescopic sleeve, a spring is sleeved on the telescopic sleeve, and a displacement sensor for detecting the displacement of the limiting block is provided inside the detector.

[0011] Preferably, the pushing component includes a cylinder body, which is mounted on a support block, and a cylinder push rod is provided at the output end of the cylinder body.

[0012] Preferably, the support block is provided with a fixed seat, and a transmission rod is slidably connected to the fixed seat. The cylinder push rod is attached to the lower end of the transmission rod, and a connecting rod connected to the telescopic sleeve rod is provided at the end of the transmission rod away from the cylinder push rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the soft-pack battery material is transported to the probe through the production line. During the production of the material, the highest position of the material is kept consistent. Then, the probe is driven to move upward by the pushing component until it is in contact with the bottom of the material. At this time, the displacement of the probe is detected by the displacement sensor inside the probe. Then, the thickness of the material is measured by subtracting the displacement from the height of the highest position of the material. Moreover, when the probe detects the material, it only needs to be in contact with the bottom of the material. This method, compared with the fixture-type detection, will not cause wear on the material, thus ensuring the quality of soft-pack battery production.

[0014] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please refer to the appendix carefully. Figures 1-4 A tooling for measuring the thickness of a soft-pack battery includes a base 1, a support block 4 on the base 1, a drive assembly on the base 1 for driving the support block 4 to move laterally, a probe 8 on the support block 4 for detecting the thickness of the soft-pack battery material, and a contact sensor on the probe 8 for contacting the bottom end face of the material to be measured. A push assembly on the support block 4 for driving the probe 8 to move up and down.

[0025] The specific operating procedure of this utility is as follows: The support block 4 is moved by the drive component to move the probe 8 to the material production outlet of the production line. After the material is produced by the production line, it is transported above the probe 8. The production line ensures that the highest point of the material is consistent. When the material is above the probe 8, the push component is activated, which moves the probe 8 upward. The probe 8 will then be in contact with the bottom of the material. At this time, the push component stops moving and begins to reset. The probe 8 measures the displacement. Then, the thickness of the material can be measured by subtracting the displacement of the probe 8 from the distance of the highest point of the material (here, the distance of the highest point of the material is the height of the sensing chip when the probe 8 is at its lowest position is taken as 0 point, and the distance from the lowest position to the bottom end face of the material is the displacement of the probe 8).

[0026] Please refer to Figure 1 and Figure 3The drive assembly includes a screw 2, which is rotatably connected to the base 1. A handle 3 is sleeved on one end of the screw 2, and a support block 4 is threaded onto the screw 2.

[0027] Rotate handle 3, which drives screw 2 to rotate. The support block 4 has a threaded hole that matches screw 2. The base 1 is equipped with a slide rail to limit and support block 4, so that support block 4 can move in a straight line. The rotation of screw 2 drives support block 4 to move horizontally left and right.

[0028] Please refer to Figures 1-3 A detector 6 is installed on the support block 4, a telescopic sleeve 7 is installed on the detector 6, a probe 8 is installed at the lower end of the telescopic sleeve 7, and a contact sensor is installed on the probe 8.

[0029] A contact-type sensing chip is provided on the end face where the probe 8 connects to the telescopic sleeve 7. When the sensing chip contacts the bottom of the material, it transmits a signal to the pushing component, which then stops rising and begins to descend and reset.

[0030] Please refer to Figures 1-4 A support base 5 is provided on the support block 4. The support base 5 is located directly below the detector 6. The probe 8 is pressed down on the support base 5. A limiting block 14 is provided on the telescopic sleeve 7. A spring 15 is sleeved on the telescopic sleeve 7. The top of the spring 15 is fixed. A displacement sensor for detecting the displacement of the limiting block 14 is provided inside the detector 6.

[0031] The support base 5 is used to limit the probe 8 to its lowest position. When the push rod assembly drives the telescopic sleeve 7 to rise, the telescopic sleeve 7 pulls the probe 8 to rise. As the telescopic sleeve 7 rises, the limiting block 14 on the telescopic sleeve 7 will compress the spring 15. When the push assembly releases its force and no longer pushes the telescopic sleeve 7 to rise, the spring 15 will rebound and reset. The displacement of the spring 15 is detected by the displacement sensor preset inside the detector 6. Then, the thickness of the material is obtained by subtracting the displacement of the spring 15 from the height of the material's upper surface.

[0032] Please refer to Figures 1-3 The pushing component includes a cylinder body 9, which is mounted on a support block 4. A cylinder push rod 10 is provided at the output end of the cylinder body 9. A fixed seat 11 is provided on the support block 4. A transmission rod 12 is slidably connected to the fixed seat 11. The cylinder push rod 10 is attached to the lower end of the transmission rod 12. A connecting rod 13 connected to the telescopic sleeve rod 7 is provided at the end of the transmission rod 12 away from the cylinder push rod 10.

[0033] When the cylinder body 9 is activated, the cylinder push rod 10 on the cylinder body 9 is pushed upward. The cylinder push rod 10 rises and fits against the lower end of the transmission rod 12. The cylinder push rod 10 pushes the upper transmission rod 12 to rise. The transmission rod 12 drives the telescopic sleeve rod 7 to rise synchronously through the connecting rod 13. The fixed seat 11 is used to support and limit the transmission rod 12 to maintain linear lifting and lowering movement.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
