[0029] The battery box conveying method of the conveying device capable of positioning the battery box and improving the conveying accuracy of the battery box according to the present utility model includes the following steps:

[0030] S1. According to the size of the battery box 100, control the limiting rod 47 of the crank rocker limiting device 4 to move to the side position of the battery box 100 to limit the side of the battery box 100. The specific control method is as follows: First, control the motor 41 to drive the push rod 42 to expand and contract. Then, the push rod 42 pushes the crank 43 to rotate. Next, the crank 43 drives the rocker 44 and the gear 45 to rotate. Then, the gear 45 drives the rack bar 46 to move. Finally, the rack bar 46 drives the limiting rod 47 to reach the side position of the battery box 100.

[0031] S2. Place the battery box 100 on the front end of the conveying track 2, and control the cylinder positioning device 3 to quickly position the battery box 100. After the quick positioning, perform the first step of the assembly processing procedure on the battery box 100.

[0032] S3. After the first step of the assembly processing procedure is completed, control the cylinder positioning device 3 to release the positioning of the battery box 100.

[0033] S4. Control the stepping pushing device 5 to push the battery box 100 to step forward by one station on the conveying track 2 to perform the second step of the assembly processing procedure on the battery box 100. After the second step of the assembly processing procedure is completed, control the stepping pushing device 5 to push the battery box 100 to step forward by one station on the conveying track 2 to perform the third step of the assembly processing procedure on the battery box 100. And so on, until the last step of the assembly processing procedure for the battery box 100 is completed.

[0034] In the above step S4, the stepping pushing device 5 performs pushing according to the following working steps: First, control the linear motor 53 on the linear guide 51 to move forward along the linear guide 51. When the pushing plate 523 of the pushing mechanism 52 touches the bottom of the battery box 100, it can swing backward and tilt against the elastic force of the spring 524, so that the pushing mechanism 52 can move forward from below the battery box 100 to the front of the battery box 100, and the pushing plate 523 of the pushing mechanism 52 swings upward and resets to stand upright under the action of the spring 524; Then, control the linear motor 53 on the linear guide 51 to move backward along the linear guide 51. When the pushing plate 523 of the pushing mechanism 52 touches the bottom of the battery box 100, since the pushing plate 523 of the pushing mechanism 52 is blocked by the baffle 528 and cannot swing forward and tilt, therefore, the pushing plate 523 of the pushing mechanism 52 can resist against the battery box 100 and push the battery box 100 backward to the designated position.

[0035] The above are only the preferred embodiments of the present invention. Any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical solutions of the present invention are all within the scope of the technical solutions of the present invention.
