[0022] The present invention will be further described below through specific embodiments with reference to the accompanying drawings.

[0023] Example: Figure 1-3 As shown, a cylindrical battery sealing plane detection device includes a frame 1, a plane detection component 3 and a feeding component 5 arranged on the frame 1;

[0024] The frame 1 includes a large plate 11, to which a detection frame is connected, and the plane detection component 3 is installed on the detection frame. The detection frame specifically includes two upright and parallel wing plates 12 and a detection mounting plate 13 connected to the two wing plates 12. The wing plates 12 are connected to the large plate 11, and the plane detection component 3 is installed on the detection mounting plate 13.

[0025] The feeding assembly 5 includes a vertical plate 1 51 and a vertical plate 2 52, and a battery supporting plate 53 fixedly arranged between the vertical plate 1 51 and the vertical plate 2 52. The middle lower part of the vertical plate 1 51 and the vertical plate 2 52 is provided with a mounting port 51-2, and the large plate 11 passes through the mounting port 51-2 and is connected to the mounting port 51-2, which can be welded or connected by other means; a waiting area 541, a detection area 542 and a removal area 543 are provided on the battery supporting plate 53, and the detection area 542 is located below the plane detection assembly 3. Under normal circumstances, the waiting area 541 and the detection area 542 are both There is a cylindrical battery, and the plane detection component 3 detects the battery on the detection area 542, and also includes a fork mechanism 55. When the detection is completed, the fork mechanism 55 is actuated to move the inspected battery on the detection area 542 to the removal area 543 to wait for removal. At the same time, the battery to be inspected in the waiting area 541 is moved to the detection area 542. In this way, the inspected battery and the battery to be inspected are moved at the same time, that is, loading is realized at the same time during the unloading process. Compared with the traditional one-in-one and one-after movement method, the detection efficiency of the battery sealing plane detection device is greatly improved.

[0026] Specifically, the shift fork mechanism 55 includes a shift fork mounting plate 551 located below the battery support plate 53, a shift fork group connected to the shift fork mounting plate 551, the shift fork group having a shift fork 1 552, a shift fork 2 553 and a shift fork 3 554 arranged at equal intervals, and further includes a lower plate 555 arranged below the shift fork mounting plate 551, and a shifting cylinder 556 arranged on the lower plate 555 for driving the movement of the shift fork group. Figure 2 The two marks 555 in the figure refer to the same plate. When the piston rod of the material shifting cylinder 556 is extended, the shift fork group moves. Shift fork 1 552 shifts the batteries in the waiting area 541 to the detection area 542. At the same time, shift fork 2 553 shifts the batteries in the detection area 542 to the removal area 543. The vertical plate 52 is provided with three horizontal clearance openings 521 for shift fork 1 552, shift fork 2 553, and shift fork 3 554, respectively. In addition, during the shifting process, shift fork 3 554 can prevent the batteries shifted to the removal area 543 from falling, and shift fork 2 553 can prevent the batteries shifted to the detection area 542 from accidentally moving to the removal area 543.

[0027] The lower plate 555 is connected to a lower plate lifting device 557. The battery support plate 53 is provided with two vertical clearance opening groups, each of which has three vertical clearance openings 531. When the batteries in the waiting area 541 are shifted to the detection area 542 and the batteries in the detection area 542 are shifted to the removal area 543, the lower plate lifting device 557 lowers the lower plate 555, thereby causing the shift fork group to descend below the battery support plate 53. When the shift fork group descends, it passes through one of the vertical clearance opening groups. Then, the piston rod of the material shifting cylinder 556 retracts, and the position of the shift fork group changes accordingly. Then, the lower plate lifting device 557 causes the shift fork group to rise, causing it to rise above the battery support plate 53. When the shift fork group rises, it passes through the other set of vertical clearance openings. In this way, the shift fork group can realize the next round of material shifting action.

[0028] The lower plate lifting device 557 specifically includes a lifting cylinder 5571 connected to the lower plate 555 and a vertical plate 5572 connected to the lower plate 555, wherein the vertical plate 5572 is slidably connected to the vertical plate 52, and multiple vertical guide rails 522 can be provided on the vertical plate 52, and the vertical plate 5572 is connected to the vertical guide rail 522 through a slider.

[0029] The plane detection assembly 3 specifically includes several detection heads 31, a detection head mounting plate 32, and a detection head drive mechanism 33 connected to the detection head mounting plate 32 to enable the detection head mounting plate 32 to move up and down. The detection head mounting plate 32 is slidably connected to the detection mounting plate 13. Specifically, a slide rail can be provided on the detection mounting plate 13, and the detection head mounting plate 32 is connected to the slide rail via a slider.

[0030] The battery sealing plane detection device in this embodiment also includes a clamping assembly 2 for clamping the outer circle of the battery, so that the battery is more stable during detection. The clamping assembly 2 is set between the two wing plates 12, including a clamping block 1 21 and a clamping block 2 22 for clamping the cylindrical battery, a clamping block mounting block 1 23 and a clamping block mounting block 2 24 for mounting the clamping block 1 21 and the clamping block 2 22 respectively, and a clamping block mounting seat 1 25 and a clamping block mounting seat 2 26 are respectively provided below the clamping block mounting block 1 23 and the clamping block mounting block 2 24. The clamping block mounting seat 1 25 and the clamping block mounting seat 2 26 are fixedly mounted on the large plate 11, and the clamping block mounting seat 1 25 and the clamping block mounting seat 2 26 form a channel 20 for feeding, and the feeding assembly 5 is located in the channel 20. The clamping block 1 23 is slidably mounted on the clamping block 1 25, and the clamping block 2 24 is slidably mounted on the clamping block 2 26. To achieve the slidable arrangement, guide rails 29 can be provided on the top of the clamping block 1 25 and the clamping block 2 26. The clamping block 1 23 and the clamping block 2 24 are respectively mounted on the corresponding guide rails 29 via sliders. The clamping block 1 23 and the clamping block 2 24 are also provided with a clamping power mechanism 27 provided on the large plate 11. The clamping power mechanism 27 enables the clamping block 1 23 and the clamping block 2 24 to move closer to or further away from each other through a linkage mechanism 28. When the clamping block 1 23 and the clamping block 2 24 are closer to each other, the clamping block 1 21 and the clamping block 2 22 can jointly clamp the outer wall of the cylindrical battery. When the clamping block 1 23 and the clamping block 2 24 are further away from each other, the clamping block 1 21 and the clamping block 2 22 can release the outer wall of the cylindrical battery.

[0031] Specifically, the linkage mechanism 28 includes a driving block 281 connected to the clamping block mounting block 23, a reversing arm 282 whose middle part is rotatably connected to the clamping block mounting seat 26, and a connecting rod 283 connecting the driving block 281 and the reversing arm 282. The two ends of the connecting rod 283 are respectively connected to the driving block 281 and the lower part of the reversing arm 282 through a universal joint 284. The upper part of the reversing arm 282 is movably connected to the clamping block mounting seat 26. The upper part of the reversing arm 282 is provided with a movable connecting groove 285. The movable connecting groove 285 restricts a driving rod 286 connected to the clamping block mounting block 24 and providing push-pull force to the clamping block mounting block 24. The clamping power mechanism 27 provides power for the driving block 281. The large plate 11 is provided with a first making way slot 11 - 1 for accommodating the first driving block 281 , and a second making way slot 11 - 2 for accommodating the reversing arm 282 .

[0032] When the clamping power mechanism 27 is working, it acts on the driving block 281 to make the driving block 281 move. On the one hand, the driving block 281 makes the clamping block mounting block 23 move. On the other hand, the reversing arm 282 is rotated through the universal joint 284, the connecting rod 283, and the universal joint 284, so that the clamping block mounting block 2 24 moves toward the clamping block mounting block 1 23, thereby achieving the function of clamping the outer wall of the cylindrical battery.

[0033] The linked clamping mechanism only requires one power source, the clamping power mechanism 27, which reduces energy consumption.

[0034] In this embodiment, the clamping power mechanism 27 adopts a common cylinder, and the piston rod of the cylinder is connected to the driving block 1 281. In order to ensure the operation stability of the driving block 1 281, a guide rail can be configured for the driving block 1 281.

[0035] The linkage mechanism 28 is located on the side of the clamping block mounting seat 1 25 and the clamping block mounting seat 2 26, which can make full use of the vertical space instead of the horizontal space, reducing the horizontal space occupation. When the clamping mechanism is combined with various workstations in battery production, it is beneficial to reduce the factory area, and is very suitable for factories in Beijing, Shanghai, Guangzhou and Shenzhen where every inch of land is valuable.

[0036] Preferably, the clamping block 21 includes a first clamping surface 211 and a second clamping surface 212 extending vertically and forming a certain angle therebetween. The first clamping surface 211 and the second clamping surface 212 forming a certain angle cooperate with the clamping block 22 to better clamp the outer wall of the cylindrical battery.

[0037] Preferably, a clamping wheel 221 is provided on the clamping block 22. The clamping wheel 221 is used for clamping to reduce wear.

[0038] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.
