Please refer to Figure 5 and Figure 6The robot 3 is provided with a pressing block 31 for pressing the floating block 213 downward to assemble the battery cap 9 on the PCM board 81, and the positioning seat 211 is also provided with a locking mechanism 24 for locking the floating block 213 when the pressing block 31 presses the floating block 213 to a predetermined position.

[0043] In this embodiment, when the turntable mechanism 1 rotates the battery 8 to be installed to the predetermined position, the first cylinder 232 lifts the battery positioning assembly 21 and the clamping assembly 22 of the positioning mechanism 2 upward to the predetermined position. After the battery positioning assembly 21 and the clamping assembly 22 are lifted to the predetermined position, the wiring 82 of the battery 8 to be installed at the predetermined position falls into the clamping assembly 22, and the clamping assembly 22 is used to clamp and position the wiring 82 of the battery 8 to be installed, so as to ensure that the wiring 82 of the battery 8 to be installed can be accurately positioned, which is convenient for the assembly of the battery cap 9. Please refer to Figure 5 and Figure 6 At the same time, the top block 212 of the battery positioning assembly 21 lifts the PCM board 81 of the capped battery 8 to be installed upward, and the PCM board 81 of the capped battery 8 to be installed falls between the press knife assembly 216 and the floating block 213. The second cylinder 215 drives the floating block 213 to move horizontally to be close to one side of the PCM board 81 of the capped battery 8 to be installed as a reference wall of the press knife assembly 216, so that the press knife assembly 216 cooperates with the floating block 213 to clamp and position the PCM board 81 of the capped battery 8 to be installed. For the specific structure of the capped battery 8 and the battery cap 9, please refer to Fig.13 and Fig.14 Therefore, the PCM board 81 of the battery 8 to be installed and the cable 82 of the battery 8 to be installed are clamped and positioned respectively by the battery positioning assembly 21 and the clamping assembly 22 of the positioning mechanism 2, so as to achieve the purpose of firmly positioning the battery 8 to be installed, so that the robot 3 can accurately assemble the battery cap 9, thereby improving the assembly efficiency of the battery cap 9. In addition, when the robot 3 assembles the battery cap 9, the suction head of the robot 3 with the battery cap 9 is moved to the top of the positioned battery 8 to be installed and aligned, and then the suction head of the robot 3 descends and presses the floating block 213 downward through the pressing block 31 of the robot 3. When the floating block 213 descends to the assembly position (predetermined position) of the battery cap 9, the robot 3 also assembles the battery cap 9 on the PCM board 81 of the battery 8 to be installed. At the same time, the locking mechanism 24 is triggered and locks the floating block 213 that has descended to the battery cap 9 assembly position, so as to prevent the spring 214 from elastically lifting the pressed floating block 213 and pushing the battery cap 9 open when the robot 3 rises and leaves the floating block 213. The locking mechanism 24 locks the floating block 213, the robot 3 rises and leaves, the knife pressing assembly 216 and the wire clamping assembly 22 of the positioning mechanism 2 are opened, so that the PCM board 81 and the cable 82 of the battery 8 to be installed are loosened, so that the battery cap 9 can be assembled quickly, efficiently, and accurately, thereby improving the assembly efficiency of the battery cap 9.

[0044] Specifically, the positioning seat 211 is slidably mounted on the bracket 231 through a linear slide mechanism, so that the second cylinder 215 drives the positioning seat 211 to move horizontally to drive the floating block 213 to press the PCM board 81 toward the direction of the battery 8 to be capped, thereby improving the stability and reliability of the battery capping device. In addition, the positioning seat 211 is provided with a slide groove for the floating block 213 to move up and down, and the floating block 213 is slidably mounted in the slide groove to enhance the smoothness and flexibility of the floating block 213 to move up and down, so as to facilitate the robot 3 to accurately assemble the battery cap 9 and improve the assembly efficiency of the battery cap 9.

[0046] Please also refer to Figure 4 , Figure 7 and Figure 8 As a specific embodiment of the battery capping device provided by the present invention, the locking mechanism 24 includes a locking arm 241 for locking the floating block 213 and a third cylinder 242 for driving the locking arm 241 to lock the floating block 213, and the third cylinder 242 is installed on the positioning seat 211.

When the robot 3 assembles the battery cap 9, the suction head of the robot 3 descends and presses the floating block 213 downward through the pressing block 31 of the robot 3. When the floating block 213 descends to the battery cap 9 assembly position (predetermined position), the third cylinder 242 of the locking mechanism 24 drives the locking arm 241 to move horizontally to the floating block 213 to lock the floating block 213 that has descended to the battery cap 9 assembly position, so as to prevent the spring 214 from elastically lifting the pressed floating block 213 and pushing the battery cap 9 open when the robot 3 rises and leaves the floating block 213, which is conducive to assembling the battery cap 9 quickly, efficiently, and accurately, and improving the assembly efficiency of the battery cap 9.

[0051] Specifically, the pressing knife 2161 is slidably installed on the bracket 231 through a linear slide mechanism. When the second cylinder 215 drives the floating block 213 to move laterally to fit closely to one side of the PCM board 81 of the battery 8 to be installed, each fourth cylinder 2162 respectively drives the corresponding pressing knife 2161 to move from the other side of the PCM board 81 of the battery 8 to be installed toward the floating block 213 until each pressing knife 2161 presses and positions the PCM board 81 of the battery 8 to be installed, so as to achieve the purpose of firmly positioning the battery 8 to be installed, so that the robot 3 can accurately assemble the battery cap 9, thereby improving the assembly efficiency of the battery cap 9.

[0052] Please also refer to Figure 3 As a specific embodiment of the battery capping device provided by the present invention, the battery capping device also includes a photoelectric detector 4 for detecting whether the robot 3 assembles the battery cap 9 on the PCM board 81, and the photoelectric detector 4 is arranged on the positioning seat 211.

[0053] In this embodiment, after the robot 3 assembles the battery cap 9 on the battery 8 to be capped, the photoelectric detector 4 detects the assembly status of the battery cap 9 on the battery 8 to be capped (whether the battery cap 9 is mounted on the PCM board 81 of the battery 8 to be capped), thereby improving the accuracy of the battery capping device in assembling the battery cap 9 and avoiding the occurrence of defective products without assembled battery caps 9.

[0054] Please also refer to Figure 1 As a specific embodiment of the battery capping device provided by the present invention, the battery capping device also includes a first machine vision camera 5 for detecting the positioning position of the battery 8 to be capped and a controller for controlling the capping action of the robot 3 according to the positioning position information detected by the first machine vision camera 5. The first machine vision camera 5 and the robot 3 are respectively connected to the controller.

[0055] In this embodiment, after the positioning mechanism 2 positions the capped battery 8 to be installed, the first machine vision camera 5 takes a picture of the capped battery 8 to be installed, and the controller accurately positions the capped battery 8 to be installed according to the photographic information of the first machine vision camera 5, and generates a control command for controlling the robot 3 to pick up materials based on the position information of the capped battery 8 to be installed, so that the robot 3 can more accurately and quickly assemble the battery cap 9 on the capped battery 8 to be installed, with a high degree of automation, thereby improving the accuracy of the battery cap installation device in assembling the battery cap 9 and facilitating improving the assembly efficiency of the battery cap 9.

[0056] Please also refer to Figure 1 As a specific embodiment of the battery capping device provided by the present invention, the battery capping device also includes a second machine vision camera 6 for detecting whether the appearance of the battery cap 9 sucked by the robot 3 is complete and a controller for judging whether the battery cap 9 is qualified according to the appearance and position information detected by the second machine vision camera 6.

[0057] In this embodiment, after the suction cup of the robot 3 absorbs the battery cap 9, the second machine vision camera 6 takes a photo to detect the appearance of the battery cap 9 absorbed by the robot 3, and the controller analyzes and determines whether the appearance of the battery cap 9 is complete based on the photographic information of the second machine vision camera 6: if the appearance of the battery cap 9 is complete, the battery cap 9 is judged to be qualified, and the robot 3 is controlled to perform normal capping operation; if the appearance of the battery cap 9 is incomplete, the battery cap 9 is judged to be unqualified, and the robot 3 is controlled to stop the capping operation and re-absorb the battery cap 9 to avoid assembling the unqualified battery cap 9 on the battery, which affects the production quality of the battery.

[0058] The basic working principle of the battery capping device provided by the present invention is as follows: the turntable mechanism 1 drives the battery 8 to be capped to arrive at the predetermined position, the positioning mechanism 2 rises, moves forward and positions the battery 8 to be capped that has arrived at the predetermined position, the first machine vision camera 5 photographs the position of the battery 8 to be capped, the controller transmits the position information of the battery 8 to be capped to the robot 3, the robot 3 absorbs the battery cap 9, and the second machine vision camera 6 takes a photo of the appearance of the battery cap 9 absorbed by the robot 3 to ensure that the battery cap 9 absorbed by the robot 3 is a qualified product. The controller controls the robot 3 to descend and compress the buffer block. After the buffer block moves down to the designated position, the fourth cylinder 2162 controls the locking arm 241 to extend forward and lock the buffer block, and the robot 3 breaks the vacuum and rises. After the capping operation is completed, the positioning mechanism 2 descends as a whole, the buffer block moves backward, the locking arm 241 retracts, and the buffer block is reset by the elastic top-resisting action of the spring 214, completing a battery capping operation. The positioning set of the battery capping device provided by the present invention is accurate and reliable, the process flow is efficient and convenient, the process action has no interference phenomenon, and it is easy to realize automation.

The controller controls the robot 3 to perform the material picking action in a timely and accurate manner according to the positioning information detected by the second sensor 76, so that the material picking and loading action of the robot 3 is more accurate and efficient, thereby improving the loading efficiency of the battery cap loading device.

The controller determines whether the battery cap 9 is reversed and does not meet the material picking state of the robot 3 through the state information of the front and back of the battery cap 9 detected by the first sensor 75 and the second sensor 76. If the battery cap 9 is reversed, the controller controls the robot 3 not to perform the material picking action to avoid the robot 3 sucking and assembling the battery cap 9 with the front and back sides inverted and causing damage to the battery.
