Description

Technical Field

[0001] This utility model relates to the field of thickness measuring equipment technology, specifically a battery thickness measuring machine. Background Technology

[0002] Soft-pack batteries are batteries packaged in aluminum-plastic film. They offer advantages such as small size, light weight, high energy density, high safety, and flexible design. During the production of soft-pack batteries, a thickness gauge is used to inspect the thickness of the finished batteries.

[0003] However, when measuring the thickness of pouch batteries, workers usually need to manually place the pouch battery on the testing table of the thickness measuring machine. After the measurement is completed, the pouch battery needs to be manually removed, and then another pouch battery needs to be taken and the thickness measurement operation is continued in the same manner. This manual operation method is cumbersome, time-consuming, labor-intensive, and time-consuming, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a battery thickness measuring machine to solve the problems mentioned in the background art.

[0014] The guide assembly, consisting of two linear drive components and two limit baffles, can block and limit the batteries being transported on the conveyor belt, ensuring that the batteries move horizontally and linearly without shifting or tilting on the conveyor belt.

[0015] As a further embodiment of this utility model: a dust removal mechanism is provided above the conveyor belt.

[0024] The guide rail, slide, and connecting rod form a pushing mechanism to push the U-shaped frame plate. When the thickness of the tested battery meets the standard, the qualified battery can be discharged from the qualified product outlet. When the thickness of the tested battery does not meet the standard, the unqualified battery can be discharged from the unqualified product outlet, so as to facilitate the subsequent separate collection of qualified and unqualified soft-pack batteries.

[0025] The laser rangefinder is connected to a controller, and the controller is connected to the pushing mechanism.

[0026] The controller determines whether a battery is qualified based on the detected battery thickness and pushes the battery to different outlets via a pushing mechanism.

Detailed Implementation

[0037] 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.

[0038] Please see Figure 1 , Figure 2 In this embodiment of the utility model, a battery thickness measuring machine is mainly used for soft-pack batteries. As needed, it can also be used to measure the thickness of rectangular batteries, aluminum-cased batteries, etc.

[0039] The thickness measuring machine of this embodiment includes a machine base 1. A conveying trough 2 is provided on the top of the machine base 1. The left side of the conveying trough 2 is open. A conveyor belt 3 for horizontally and linearly conveying battery packs is rotatably mounted inside the conveying trough 2. A conveyor motor is installed on the machine base 1. The rotation of the conveyor belt 3 can be controlled by the operation of the conveyor motor. The assembly and connection method and control method of the conveyor belt 3 are mature technologies in the field, and therefore will not be described in detail here. A testing platform 4 is fixedly installed on the inner right wall of the conveying trough 2. The top surface of the testing platform 4 is flush with the top surface of the conveyor belt 3. The testing platform 4 is a platform for testing soft-pack batteries, and its upper surface is a smooth horizontal surface. A support frame 5 is fixedly installed on the top of the machine base 1, and the vertical end of the support frame 5 is located in the conveying trough. On the right side of 2, the horizontal end of the support frame 5 is located above the testing platform 4. A mounting plate 6 is fixedly installed on the horizontal end of the support frame 5. Multiple laser rangefinders 7 are fixedly installed on the bottom of the mounting plate 6. The multiple laser rangefinders 7 are evenly distributed in two rows. When the conveyor belt 3 transports the soft-pack battery to the testing platform 4, the vertical distance from the laser rangefinder 7 to the upper surface of the soft-pack battery is measured and subtracted from the vertical distance from the laser rangefinder 7 to the upper surface of the testing platform 4. This difference gives the thickness of the soft-pack battery. It should be noted that the vertical distance from the laser rangefinder 7 to the upper surface of the testing platform 4 can be measured in advance. By using multiple laser rangefinders 7, the thickness of different parts of the soft-pack battery can be measured, thus achieving the effect of multi-point measurement and improving the accuracy of the soft-pack battery thickness measurement results.

[0040] Please see Figure 3 In this embodiment, in order to reduce the gap between the testing platform 4 and the conveyor belt 3 and to smoothly transport the soft-pack batteries on the conveyor belt 3 to the testing platform 4, a transition plate 19 is fixedly installed on the left side wall of the testing platform 4. The top surface of the transition plate 19 is flush with the top surface of the testing platform 4, and the left side of the transition plate 19 has an arc-shaped surface structure.

[0041] The machine tool 1 is equipped with a guide assembly for guiding and limiting the conveying direction of the pouch batteries. The guide assembly includes two linear drive components 8 and two limit baffles 9. The two linear drive components 8 are fixedly installed on the front and rear side walls of the machine tool 1, respectively. The output shaft ends of the two linear drive components 8 extend into the conveying groove 2. The two limit baffles 9 are fixedly installed on the output shaft ends of the two linear drive components 8, respectively. Utilizing the telescopic feature of the two linear drive components 8, the corresponding limit baffles 9 can be controlled to move linearly, thereby facilitating the adjustment of the distance between the two limit baffles 9. By using the two limit baffles 9 in cooperation, the pouch batteries conveyed on the conveyor belt 3 can be blocked and limited, ensuring that the pouch batteries move horizontally and linearly without shifting or tilting on the conveyor belt 3. It should be noted that when conveying pouch batteries, the gap between the two limit baffles 9 and the two sides of the pouch batteries is reserved to be 1-3mm.

[0042] Please see Figure 3 The machine 1 is equipped with a pushing mechanism for pushing the tested soft-pack batteries out of the testing table 4. The pushing mechanism includes a U-shaped frame plate 14 and a driving mechanism for driving the U-shaped frame plate 14 to move horizontally. In this embodiment, the driving mechanism includes a guide rail 11, a slide 12, and a connecting rod 13. Specifically, an installation groove 10 is provided on the right inner wall of the conveying trough 2, located above the testing platform 4. A guide rail 11 is fixedly installed on the right inner wall of the installation groove 10. A slide block 12 is slidably installed on the guide rail 11. A connecting rod 13 is fixedly installed on the left side wall of the slide block 12, with the left end of the connecting rod 13 extending outside the installation groove 10. A U-shaped frame plate 14 is fixedly installed on the left end of the connecting rod 13. A first outlet 16 is provided on the front side wall of the conveying trough 2, located directly in front of the testing platform 4. A second outlet 17 is provided on the rear side wall of the conveying trough 2, located directly behind the testing platform 4. When the soft-pack battery is conveyed to the testing platform 4 by the conveyor belt 3 and comes into contact with the right inner wall of the U-shaped frame plate 14, it plays the role of positioning and conveying the soft-pack battery. By utilizing the sliding connection of the slide block 12 on the guide rail 11, the slide block 12 can drive the connecting rod 13 and the U-shaped frame plate 14 to move linearly. The U-shaped frame plate 14 can push the measured soft-pack battery on the testing platform 4 to move linearly.

[0043] In this embodiment, in order to ensure that one side of the U-shaped frame plate 14 can smoothly pass through the first outlet 16 or the second outlet 17, the length of the U-shaped frame plate 14 is smaller than the inner length of the first outlet 16, and the first outlet 16 and the second outlet 17 are set to have the same size.

[0044] In this embodiment, a controller 15 is fixedly installed on the support frame 5. The controller 15 is equipped with a display screen and multiple control buttons. Multiple laser rangefinders 7, guide rails 11, slides 12, and controller 15 are electrically connected. The data values ​​detected by the multiple laser rangefinders 7 can be displayed on the display screen for easy viewing by the staff. The multiple control buttons can be used to control the power supply and operation of the multiple laser rangefinders 7, guide rails 11, and slides 12. The sliding direction of the slide 12 on the guide rail 11 is automatically controlled by the controller 15. The data values ​​measured by the multiple laser rangefinders 7 are transmitted to the controller 15. The controller 15 automatically compares the measured data values ​​with pre-set standard data values. When the detected data value is within the standard rangefinder range... If the measured data value is within the standard range, it indicates that the thickness of the soft-pack battery meets the standard. At this time, the controller 15 issues a command to control the slide 12 to slide forward on the guide rail 11 (viewed from the main view). The U-shaped frame plate 14 can be used to discharge the qualified soft-pack battery from the first outlet 16. If the measured data value is not within the standard range, it indicates that the thickness of the soft-pack battery is unqualified. At this time, the controller 15 issues a command to control the slide 12 to slide backward on the guide rail 11 (viewed from the main view). The U-shaped frame plate 14 can be used to discharge the unqualified soft-pack battery from the second outlet 17. The control circuit of the controller 15 can be implemented by those skilled in the art through simple programming. It belongs to the mature technology in this field, so the control method and circuit connection method will not be explained in detail.

[0045] In this embodiment, in order to guide the discharged qualified or unqualified soft-pack batteries to fall smoothly, inclined U-shaped feeding plates 18 are fixedly installed on the front and rear outer walls of the machine 1. The two feeding plates 18 are respectively adapted to the first outlet 16 and the second outlet 17. It should be noted that a collection box can be placed below the two feeding plates 18 to collect qualified or unqualified soft-pack batteries respectively.

[0046] In this embodiment, it should be noted that the inner length of the U-shaped frame plate 14 is smaller than the length of the soft-pack battery, and the length of the soft-pack battery is smaller than the inner length of the first outlet 16 and the second outlet 17. Therefore, when the soft-pack battery at the front is pushed and pushed into the U-shaped frame plate 14 by the soft-pack battery at the rear of the conveyor belt 3, the soft-pack battery at the rear will not enter the U-shaped frame plate 14, which does not affect the subsequent horizontal movement and ejection of the detected soft-pack battery using the U-shaped frame plate 14.

[0047] Please see Figure 4In this embodiment, a telescopic rod 20 is fixedly installed at the bottom of the support frame 5, and a pressure plate 21 is fixedly installed at the output shaft end of the telescopic rod 20. The pressure plate 21 is located directly above the conveyor belt 3. Utilizing the telescopic feature of the telescopic rod 20, the vertical movement of the pressure plate 21 can be controlled. The downward vertical pressure applied by the pressure plate 21 can be used to fine-tune the bulges on the surface of the soft-pack battery, effectively reducing the bulge area and improving the quality of the soft-pack battery. An air pump 22 is fixedly installed at the bottom of the support frame 5, located between the telescopic rod 20 and the mounting plate 6. The output shaft of the air pump 22... An air pipe 23 is fixedly installed at one end, and an air chamber 24 is opened inside the pressure plate 21. Multiple air blowing holes 25 are arranged in an array on the bottom inner wall of the air chamber 24. A pipe connector 26 is fixedly installed on the top of the pressure plate 21 and is connected to the air chamber 24. One end of the air pipe 23 is fixedly connected to the pipe connector 26. By operating the air pump 22, air can be injected into the air chamber 24, and then the air can be discharged from the multiple air blowing holes 25, which can blow away the dust and debris on the surface of the soft pack battery and improve the accuracy of the subsequent thickness detection results of the soft pack battery.

[0048] In this embodiment, the thickness measuring machine can transport pouch batteries to the inspection table 4 at a fixed point, and can measure the thickness of different parts of the pouch batteries, achieving multi-point measurement and improving the accuracy of the thickness measurement results. Furthermore, it can push out qualified and unqualified pouch batteries from different directions, facilitating subsequent separate collection of qualified and unqualified pouch batteries, reducing the workload of workers, saving time, and improving work efficiency. Specifically, by controlling the extension of the two linear drive components 8, the two limit baffles 9 can be controlled to move closer to each other. When the distance between the two limit baffles 9 is adjusted to be slightly larger than the width of the pouch battery, the operation of the two linear drive components 8 is stopped. Then, a large number of pouch batteries are placed one by one between the two limit baffles 9 on the conveyor belt 3. The conveyor belt 3 can be used to transport the soft-pack battery horizontally in a straight line. When the frontmost soft-pack battery is transported to the bottom of the pressure plate 21, the conveyor belt 3 is paused. The air pump 22 is then controlled to run, which can fill the air chamber 24 with air. The air is then discharged from multiple air holes 25, which can blow away the dust and debris on the surface of the soft-pack battery, thereby improving the accuracy of the subsequent thickness test results of the soft-pack battery. After the surface of the soft-pack battery is cleaned, the air pump 22 is turned off. Then, by controlling the extension rod 20 to extend, the pressure plate 21 can be controlled to move vertically downward. The pressure plate 21 applies a vertical downward force to the soft-pack battery, which can be used to fine-tune the bulges on the surface of the soft-pack battery, effectively reducing the bulge area and improving the quality of the soft-pack battery. After the soft-pack battery is pressed, the pressure plate 21 can be controlled to rise vertically back to its original position by controlling the extension rod 20 to retract and reset. Then, the conveyor belt 3 can be controlled to continue to rotate.

[0049] When the foremost pouch battery on conveyor belt 3 is transported to the testing table 4, as it continues to transport the pouch batteries behind it, the pouch battery behind the foremost one will push it into the U-shaped frame plate 14 and abut against the inner right wall of the U-shaped frame plate 14. At this time, the rotation of conveyor belt 3 is paused, and multiple laser rangefinders 7 are started to operate, which can detect the thickness of different parts of the pouch battery, thus achieving the effect of multi-point measurement. When the detected data value is within the standard data value range, it means that the thickness of the pouch battery meets the standard and is qualified. At this time, the controller 15 issues a command to control the slide. 12 slides forward on guide rail 11 (viewed from the main view). The U-shaped frame plate 14 can discharge the qualified soft-pack battery from the first outlet 16. When the detected data value is not within the standard data value range, it means that the thickness of the soft-pack battery is unqualified. At this time, the controller 15 issues a command to control the slide 12 to slide backward on guide rail 11 (viewed from the main view). The U-shaped frame plate 14 can discharge the unqualified soft-pack battery from the second outlet 17. Then, the conveyor belt 3 is controlled to continue running. Following the above operation steps, the thickness of the next soft-pack battery can be detected.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
