Description

Technical Field

[0001] The utility model relates to the field of battery thickness measuring equipment, in particular to a thickness measuring mechanism with a dust removal function. Background Art

[0002] In the production process of soft-pack batteries, the thickness of the aluminum-plastic film packaging of soft-pack batteries is a key parameter to characterize the packaging quality. Once the packaging is poor, it is easy to cause leakage and other adverse phenomena. Therefore, it is usually necessary to confirm the thickness consistency of the packaging area during the debugging stage and measure the thickness of the aluminum-plastic film packaging of the soft-pack batteries.

[0003] In measuring the thickness of the aluminum-plastic film packaging of soft-pack batteries, there are two traditional thickness measurement methods. One is non-contact measurement, which uses a laser sensor to measure the thickness of the aluminum-plastic film packaging of soft-pack batteries. Since the outer material of the aluminum-plastic film has a great interference with the laser sensor measurement, it leads to a large measurement error; the other is contact measurement, in which the battery is pressed tightly by the upper and lower molds, and the thickness measuring probe installed on the upper mold contacts the lower mold, and the thickness of the battery is calculated by the compression distance of the thickness measuring probe.

[0004] When using contact measurement, the dust on the battery is easy to adhere to the pressure plate of the upper mold and accumulate, which has an adverse effect on the subsequent thickness measurement accuracy. Manual dust removal of the upper mold is not only inconvenient to operate, but also has low dust removal efficiency. Therefore, it is necessary to produce a thickness measuring mechanism with dust removal function to solve the above problems. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figures 1 to 5 As shown, a thickness measuring mechanism with a dust removal function comprises an X-axis driving assembly 1, a movable base plate 2, a battery carrier 3, a dust removal assembly 4, a mounting bracket 5, a Z-axis driving assembly 6, a thickness measuring plate 7 and a probe assembly 8, wherein the movable base plate 2 is fixed at the power output end of the X-axis driving assembly 1, the battery carrier 3 is arranged in two groups and is fixed side by side on the upper side of the movable base plate 2, the dust removal assembly 4 is arranged in two groups and is respectively fixed at the left and right ends of the movable base plate 2, the mounting bracket 5 is erected above the X-axis driving assembly 1, the Z-axis driving assembly 6 is fixed at the upper end of the mounting bracket 5, the thickness measuring plate 7 is fixed at the power output end of the Z-axis driving assembly 6 and is slidably connected to the mounting bracket 5, the probe assembly 8 is fixed on the platen and the detection end corresponds to the upper side of the battery carrier 3, and the mounting bracket 5, the Z-axis driving assembly 6, the thickness measuring plate 7 and the probe assembly 8 are all arranged in two groups and correspond to the left and right sides of the X-axis driving assembly 1 respectively;

[0022] The dust removal assembly 4 includes a Z-axis cylinder 41, a connecting ear 42, a brush fixing seat 43 and a dust removal brush 44. The Z-axis cylinder 41 is fixed to the front and rear ends of the movable base plate 2. The connecting ear 42 is provided with an arc hole 421. The connecting ear 42 is fixed to the front and rear ends of the brush fixing seat 43 by means of screws passing through the arc hole 421. The connecting ear 42 is fixed to the power output end of the Z-axis cylinder 41. The dust removal brush 44 is fixed to the brush fixing seat 43 with the free end facing outward in an oblique direction.

[0023] When the X-axis driving assembly 1 drives the movable base plate 2 to move left and right, so that the battery carriers 3 on the left and right sides alternately move under the two groups of mounting brackets 5, and the Z-axis driving assembly 6 drives the thickness measuring plate 7 to press down on the upper end surface of the battery. At the same time, the probe assembly 8 descends, and the detection end touches the battery carrier 3, so as to detect the thickness of the battery. When one group of battery carriers 3 is in the detection state, the other group of battery carriers is in the middle position, so as to take out the batteries that have been tested and put in the next group of batteries to be tested. Before the middle battery carrier moves under the thickness measuring plate 7, the Z-axis cylinder 41 drives the connecting ear 42 and the brush fixing seat 43 to rise, so that the top of the dust removal brush 44 is higher than the bottom surface of the thickness measuring plate 7. When the battery carrier moves under the thickness measuring plate 7, the dust removal brush 44 first wipes the thickness measuring plate 7, thereby automatically removing the dust on the thickness measuring plate 7, which can improve the efficiency and effect of dust removal and the accuracy of battery thickness detection. The connecting ear 42 is fixed to the brush fixing seat 43 by a screw passing through the arc hole 421. The angle of the brush fixing seat 43 can be flexibly adjusted to improve the wiping effect of the thickness measuring plate 7. The free end of the dust removal brush 44 is inclined to the outside to prevent dust from entering the interior of the equipment.

[0024] The battery carrier 3 includes a carrier pressure block 31, a carrier body 32 and a pressure plate 33. Two groups of carrier pressure blocks 31 are arranged and fixed above the movable bottom plate 2. The left and right ends of the carrier body 32 are slidably connected with the two groups of carrier pressure blocks 31. The pressure plate 33 is provided with a strip hole 331. The pressure plate 33 is fixed above the carrier pressure block 31 by screws passing through the strip hole 331. The two groups of pressure plates 33 correspond to the left and right sides above the carrier body 32.

[0025] The carrier body 32 is slidably connected to the carrier pressure block 31, so that the carrier body 32 can be pulled out from between the two groups of carrier pressure blocks 31 for replacement, thereby improving the efficiency of the replacement. The pressure plate 33 can limit the left and right sides of the battery. At the same time, when the battery is leaking, the thickness measuring pressure plate 7 stops pressing on the pressure plate 33 to avoid excessive pressure and damage to the probe assembly 8. The pressure block is provided with a strip hole 331, so that the position of the pressure block can be adjusted to accommodate batteries of different widths.

[0026] The probe assembly 8 includes a fixed bracket 81, a movable bracket 82, an adjusting screw 83 and a thickness measuring probe 84. The fixed bracket 81 is fixed above the thickness measuring plate 7. The movable bracket 82 is fixed on the fixed bracket 81 and can be adjusted in the vertical direction. The movable bracket 82 passes through the thickness measuring plate 7. The upper end of the adjusting screw 83 is rotatably mounted on the fixed bracket 81, and the lower end is threadedly connected to the upper end of the movable bracket 82. The thickness measuring probe 84 is fixed at the lower end of the movable bracket 82 with the detection end facing downward.

[0027] By rotating the adjusting screw 83, the vertical position of the movable bracket 82 can be fine-tuned, thereby adjusting the position of the thickness measuring probe 84 to adapt to the detection of batteries with different thickness specifications.

[0028] The mounting bracket 5 is provided with an air avoidance hole 51, which corresponds to the top of the probe assembly 8. The upper end of the probe assembly 8 can pass through the air avoidance hole 51, so that the rising distance of the thickness measuring plate 7 is increased or the height of the mounting bracket 5 can be made shorter, so as to make full use of the equipment space.

[0029] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
