Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 - Figure 5 As shown, a lithium battery thickness measurement device includes a device body 1; four sets of legs 2 are fixedly connected to the bottom end of the device body 1, and the four sets of legs 2 are arranged in a linear array around the bottom end of the device body 1. A first transmission belt 3 is provided inside the device body 1, a laser sensor 4 is provided directly above the device body 1, and a transmission mechanism is provided on the outside of the first transmission belt 3;

[0024] The transmission mechanism includes a fixed rod 5, which is fixedly connected to the outer side of the first transmission belt 3, and the first spur gear 6 is installed on the end of the fixed rod 5 away from the first transmission belt 3, and the second spur gear 7 is meshed with the first spur gear 6 on one side. A connecting rod is installed inside the second spur gear 7, and the connecting rod is rotatably connected to the inner wall of the device body 1. The end of the connecting rod away from the second spur gear 7 is installed with a first rotating shaft 8, and a crawler 9 is wound around the outer side of the first rotating shaft 8, and the second rotating shaft 10 is wound around the end of the crawler 9 away from the first rotating shaft 8. One end of the second rotating shaft 10 is rotatably connected to the connecting frame 66, and the other end of the second rotating shaft 10 is fixedly connected to the first connecting shaft 11, and the end of the first connecting shaft 11 away from the second rotating shaft 10 is rotatably connected to the connecting frame 66. The connecting frame 66 is rotatably connected to the second connecting shaft 12, and the second transmission belt 13 is wound around the outer sides of the first connecting shaft 11 and the second connecting shaft 12;

[0025] During operation, the structural design of the transmission mechanism realizes the function of saving the first transmission belt 3 from stopping and waiting, and solves the problem that the first transmission belt 3 needs to stop and wait for the laser sensor 4 to measure when the lifting platform drives the laser sensor 4 to descend. This process reduces the efficiency of the measurement work, that is, it is necessary to wait for the beat of the first transmission belt 3 to stop, and the problem that the next group of measurements cannot be carried out when the upper group of measurements is not completed, thereby improving the efficiency of the measurement work. When the first transmission belt 3 is running, it drives the fixed rod 5 to rotate, and the rotation of the fixed rod 5 will synchronously drive the first spur gear 6 to rotate, and the rotation of the first spur gear 6 will drive the second spur gear 7 rotates. Since a connecting rod is installed inside the second spur gear 7, the rotation of the second spur gear 7 drives the connecting rod to rotate, and the rotation of the connecting rod drives the first rotating shaft 8 to rotate synchronously. At this time, the crawler track 9 drives the second rotating shaft 10 to rotate through the rotation of the first rotating shaft 8, and the rotation of the second rotating shaft 10 drives the first connecting shaft 11 to rotate. The second transmission belt 13 then drives the second connecting shaft 12 to rotate through the rotation of the first connecting shaft 11. At this time, the rotation direction of the second transmission belt 13 is opposite to that of the first transmission belt 3. It should be noted that the rotation rate of the first transmission belt 3 is the same as the rotation rate of the second transmission belt 13.

[0026] Further, such as Figure 1 and Figure 2 As shown, the fixing platforms 14 are provided in multiple groups, and the multiple groups of fixing platforms 14 are evenly distributed on the outside of the second transmission belt 13;

[0027] During operation, the fixing platform 14 is provided with multiple groups that can be used in conjunction with lithium batteries. At this time, when testing the lithium batteries, there is no need to wait for the first transmission belt 3 to stop, and the testing can be achieved without stopping.

[0028] Further, such as Figure 2 and Figure 4As shown, a plurality of groups of the laser sensors 4 are provided with fixed platforms 14 on the outside, and the fixed platforms 14 are all distributed on the outside of the second transmission belt 13;

[0029] During operation, the setting of the fixing platform 14 can provide an installation space for the internal laser sensor 4, so that the laser sensor 4 is always inside the fixing platform 14, thereby preventing the laser sensor 4 from falling.

[0030] Further, such as Figure 2 and Figure 4 As shown, a device slot is provided inside the fixing platform 14, and a limit plate 15 is provided inside the device slot. The limit plate 15 is fixedly connected to the laser sensor 4;

[0031] During operation, the setting of the limiting plate 15 can limit the laser sensor 4 to prevent the laser sensor 4 from falling off.

[0032] Further, such as Figure 2 and Figure 4 As shown, a pair of limiting rods 16 are provided inside the device slot, both ends of the pair of limiting rods 16 are fixedly connected to the inner wall of the device slot, and the limiting rods 16 pass through the limiting plate 15;

[0033] During operation, the setting of a pair of limiting rods 16 can limit the limiting plate 15, making the limiting plate 15 more stable when moving and preventing the limiting plate 15 from shaking when moving.

[0034] Further, such as Figure 4 and Figure 5 As shown, a device platform 17 is provided inside the first transmission belt 3, and both ends of the device platform 17 are fixedly connected to the inner wall of the device body 1. A magnetic stone 18 is provided on the top of the device platform 17, and a magnetic ring 19 is provided on the outside of the laser sensor 4. The magnetic stone 18 and the magnetic ring 19 repel each other;

[0035] During operation, the setting of the device table 17 can provide installation space for the magnetic stone 18. When the laser sensor 4 approaches the first transmission belt 3, the laser sensor 4 is flipped 180° like a magnetic stone. The laser sensor 4 is approached to the first transmission belt 3 under the action of gravity to facilitate the measurement of the workpiece at the top of the first transmission belt 3. The magnetic ring 19 and the magnetic stone 18 repel each other at this time to prevent the detection head of the laser sensor 4 from directly contacting the workpiece and causing collision and damage to the workpiece.

[0036] Working principle: Through the structural design of the transmission mechanism, the function of saving the first transmission belt 3 from stopping and waiting is realized, and the problem of the first transmission belt 3 needing to stop and wait for the laser sensor 4 to measure when the lifting platform drives the laser sensor 4 to descend is solved. This process reduces the efficiency of the measurement work, that is, it is necessary to wait for the beat of the first transmission belt 3 to stop, and the problem of the next group of measurements cannot be carried out when the upper group measurement is not completed, thereby improving the efficiency of the measurement work. When the first transmission belt 3 is running, it drives the fixed rod 5 to rotate, and the rotation of the fixed rod 5 will synchronously drive the first spur gear 6 to rotate, and the rotation of the first spur gear 6 will drive the second spur gear 7 to rotate. Since a connecting rod is installed inside the second spur gear 7, the rotation of the second spur gear 7 drives the connecting rod to rotate, and the rotation of the connecting rod will drive the first rotating shaft 8 to rotate synchronously. At this time, the crawler 9 drives the second rotating shaft 10 to rotate through the rotation of the first rotating shaft 8, and the rotation of the second rotating shaft 10 drives the first connecting shaft 11 to rotate. The second transmission belt 13 then drives the second connecting shaft 12 to rotate through the rotation of the first connecting shaft 11. At this time, the rotation direction of the second transmission belt 13 is opposite to that of the first transmission belt 3. It should be noted that the first transmission The speed of rotation of the driving belt 3 is the same as the speed of rotation of the second transmission belt 13. The fixed platform 14 is provided with multiple groups for use with lithium batteries. At this time, when testing the lithium battery, there is no need to wait for the first transmission belt 3 to stop, and non-stop testing can be achieved. The setting of the fixed platform 14 can provide an installation space for the internal laser sensor 4, so that the laser sensor 4 is always inside the fixed platform 14 to prevent the laser sensor 4 from falling. The setting of the limit plate 15 can limit the laser sensor 4 to prevent it from falling off. The setting of a pair of limit rods 16 can limit the limit plate 15 The limiting effect makes the limiting plate 15 more stable when moving and prevents the limiting plate 15 from shaking when moving. The setting of the device table 17 can provide installation space for the magnetic stone 18. When the laser sensor 4 is close to the first transmission belt 3, the laser sensor 4 is flipped 180° like a magnetic stone. The laser sensor 4 is close to the first transmission belt 3 under the action of gravity to facilitate the measurement of the workpiece at the top of the first transmission belt 3. The magnetic ring 19 and the magnetic stone 18 repel each other at this time to prevent the detection head of the laser sensor 4 from directly contacting the workpiece, which may cause collision and damage to the workpiece.
