DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] Referring to Figures 1 to 4 The thickness detector for the battery cell heat insulation sheet in the embodiment comprises a workbench 1 and a conveying belt device 2 fixedly installed on the top of the workbench 1. The top of the workbench 1 is fixedly connected with a supporting plate 3. The top of the supporting plate 3 is fixedly connected with a mounting seat 4 extending to the top of the conveying belt device 2. The front of the mounting seat 4 is provided with a continuous feeding mechanism capable of feeding. The continuous feeding mechanism comprises a drive box 5 fixedly connected to the back of the mounting seat 4. The bottom of the drive box 5 is fixedly connected with an electric push rod 6. The output end of the electric push rod 6 is fixedly connected with a moving plate 7. A driven gear 9 is rotationally connected in the drive box 5. A rack 8 meshing with the driven gear 9 is slidingly connected in the drive box 5. The front of the mounting seat 4 is rotationally connected with a rotating connecting rod 10. One end of the rotating connecting rod 10 is rotationally connected with a lifting connecting rod 11. The end of the lifting connecting rod 11 close to the conveying belt device 2 is fixedly connected with a suction disc device 12.

[0025] Specifically, a connecting block is fixedly connected between the moving plate 7 and the rack 8. An active slot matching the connecting block is formed on the lower surface of the drive box 5. The front of the driven gear 9 is fixedly connected with one end of the rotating connecting rod 10. The front of the mounting seat 4 is fixedly installed with a limiting guide rail 14. The front of the limiting guide rail 14 is slidingly connected with a limiting seat 13. The limiting seat 13 is slidingly connected with the lifting connecting rod 11.

[0026] It should be noted that the back of the lifting connecting rod 11 is fixedly connected with a positioning strip extending into the inside of the limiting seat 13. The front of the limiting seat 13 is provided with a positioning slot matching the positioning strip.

[0027] It should be noted that the electric push rod 6 is arranged to drive the moving plate 7 and the rack 8 to move left and right, so that the rack 8 can drive the driven gear 9 to rotate during movement, and in turn drive the rotating connecting rod 10 to rotate. At this time, the lifting connecting rod 11 and the suction disc device 12 are arranged to in turn realize the reciprocating movement of the suction disc device 12, achieving the effect of continuously feeding the heat insulation sheet body 16.

[0028] Referring to Figure 1 and Figure 2 In the embodiment, the top of the workbench 1 is fixedly installed with a storage cylinder 15. The inside of the storage cylinder 15 is provided with a heat insulation sheet body 16. The inner bottom wall of the storage cylinder 15 is fixedly connected with a mounting sleeve 17. The top of the mounting sleeve 17 is slidingly connected with a connecting rod 18 extending into the inside thereof. The connecting rod 18 is fixedly connected with a return spring 19 between the mounting sleeve 17. The top end of the connecting rod 18 is fixedly connected with a pushing plate 20. The heat insulation sheet body 16 abuts against the pushing plate 20.

[0029] Specifically, the number of installation sleeves 17 is two, and the two installation sleeves 17 are symmetrically distributed in the interior of the storage cylinder 15, and the outer wall of the pushing plate 20 is in contact with the inner wall of the storage cylinder 15.

[0030] It should be noted that the upper surface of the storage cylinder 15 is fixedly connected with a material blocking block capable of positioning the heat insulation sheet body 16. Since the heat insulation sheet body 16 is relatively thin and soft, the material blocking block can position the heat insulation sheet body 16 on one hand, avoid the case of material overflow caused by excessive pushing force, and on the other hand, will not affect the feeding effect of the heat insulation sheet body 16.

[0031] Please refer to Figure 1 In the embodiment, the top of the workbench 1 is fixedly provided with a support frame 21 extending to the top of the conveying belt device 2, and the lower surface of the support frame 21 is fixedly provided with a thickness detection device 22.

[0032] Specifically, the thickness detection device 22 is a laser thickness gauge. The thickness of the heat insulation sheet is calculated by measuring the time from the emission of laser to the reflection back of laser by using the reflection principle of laser. This method is non-contact measurement and will not cause damage to the heat insulation sheet. The measurement precision is high and can reach micrometer level. Moreover, the measurement speed is fast and is suitable for online detection and batch measurement.

[0033] The working principle of the above embodiment is as follows:

[0034] Firstly, the staff places a large number of heat insulation sheet bodies 16 in the interior of the storage cylinder 15, and the heat insulation sheet bodies 16 are in abutment with the pushing plate 20. Then, the staff starts the conveying belt device 2 and the electric push rod 6 at the same time. At this time, the electric push rod 6 drives the lifting link 11 and the suction cup device 12 to reciprocate, so as to continuously feed the heat insulation sheet bodies 16 to the conveying belt device 2. When the heat insulation sheet bodies 16 pass through the thickness detection device 22, the thickness of the heat insulation sheet bodies 16 can be detected.

[0035] The installation method, connection method or setting method disclosed in the embodiment are all common mechanical connection methods, as long as the beneficial effects can be achieved. In addition, the electrical elements appearing in the embodiment are electrically connected with the main control unit and the power supply. The main control unit can be a conventional known device such as a computer which plays a control role. The control of the electrical elements can be realized by simple programming by the person skilled in the art. The existing disclosed power connection technology also belongs to the common knowledge in the art. Therefore, the specific structure and working principle of the electrical elements will not be described in detail.
