Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing equipment, and more particularly to a surface defect screening device for cylindrical batteries. Background Technology

[0002] The screening process for cylindrical battery surfaces mainly includes visual inspection, dimensional inspection, cleanliness inspection, and labeling inspection. Visual inspection primarily involves using visual inspection or machine vision systems to check for defects such as scratches, dents, and bubbles on the battery surface. Dimensional inspection uses high-precision measuring instruments to measure the battery's length, width, and height to ensure it meets design specifications.

[0003] Existing cylindrical battery surface screening devices often use high-definition cameras to collect information during operation, and then judge the collected information to determine the state of the cylindrical batteries. However, since there may be dust on the surface of the batteries being screened, the dust may block the lens of the high-definition camera during long-term operation, which will lead to inaccurate information collection. Summary of the Invention

[0004] Therefore, this invention addresses the aforementioned problems. The purpose of this invention is to solve the problem of dust potentially accumulating on the surface of the screening battery through a cleanable lens design. This dust can obstruct the lens during prolonged operation of high-definition video equipment, leading to inaccurate information acquisition. This invention achieves the above objective through the following technical solution.

[0005] A surface defect screening device for cylindrical batteries includes: a driving device disposed on the upper wall of a platform, the driving device including a motor and a first screw rod, the motor being fixed to the upper surface of the platform, the screw rod being coaxially connected to the output shaft of the motor; a moving device including a moving plate, a driving block, and round rods, the first screw rod meshing with the moving plate, the moving plate containing a driving block that can slide up and down, two round rods on the side wall of the driving block, the lower end of the moving plate being embedded in a slide rail of the platform, the track consisting of a smooth track and an inclined track, the smooth track being horizontally disposed on one side of the platform, the inclined track being connected to the end of the smooth track and inclined downwards; a control plate hinged to the upper surface of the platform via a rotating shaft; and a rotating device including a rotating block, a second screw rod, an elastic telescopic rod, and a one-way rotating bearing, the rotating block being rotatably disposed on the surface of the control plate, the elastic telescopic rod being connected to one end of the second screw rod, and the one-way rotating bearing being disposed at the meshing point between the rotating block and the second screw rod.

[0006] Preferably, the top round rod of the drive block is provided with a forward-extending top rod, and the end of the top rod is provided with an arc-shaped guide surface.

[0007] Preferably, the guiding device includes: guide plate one, guide plate two, cleaning block one, cleaning block two, abrasive block, balance bar, and guide plate three.

[0008] Preferably, the first guide plate is disposed on both sides of the second guide plate, and the first guide plate has an opening. The second guide plate is disposed on the upper wall of the control plate via a connecting rod, and the bottom of the second guide plate has an opening. The first cleaning block is disposed on the upper end of one side of the first guide plate, and the second cleaning block is disposed on the upper end of the other side of the first guide plate. The abrasive block is rotatably disposed in the opening of the second guide plate via a connecting rod. There are two balance bars, which are rotatably disposed on the second guide plate. The third guide plate is disposed on the side of the second guide plate and has an inclined slide rail disposed thereon.

[0009] Preferably, the surface of the abrasive block is provided with friction texture, and its upper and lower end faces are in contact with the rotating block and the cylindrical battery, respectively.

[0010] Preferably, the data acquisition device includes a support rod, a first camera and two second cameras. The support rod is vertically mounted on the platform, with the first camera located in the middle of the support rod and the second camera located at both ends of the support rod.

[0011] Preferably, the cleaning block one is directly opposite the bottom of the right camera two, and the vertical edge of the cleaning block two is located at the top of the left camera one.

[0012] Preferably, the extension and retraction direction of the elastic telescopic rod coincides with the axis of the second spiral rod, and a compression spring is provided inside to keep the second spiral rod extending outward.

[0013] Preferably, the platform is provided with a positioning block, which is located below the rotation path of the control plate, limiting the maximum rotation angle of the control plate to a horizontal state.

[0014] This invention uses a motor-driven circular rod to move and collide with a second spiral rod, causing it to move towards an elastic telescopic rod. The movement of the second spiral rod drives a one-way rotating bearing to rotate, which in turn drives a rotating block to rotate. The rotation of the rotating block drives a cylindrical battery to rotate, causing various areas on its side to be captured by a camera.

[0015] This invention uses a motor drive and track guidance. The different moving directions of the round rod can drive the cylindrical battery through the opening of the guide plate and the three slides of the guide plate to complete the collection.

[0016] This invention uses a downward-sloping guide plate to clean two cameras by having them contact cleaning blocks one and two on their sides. As the cylindrical battery moves with the rod, the side of cleaning block two can also clean camera one. As data collection continues, the lens can be cleaned in an orderly manner. This avoids dust that may be present on the surface of the battery. Therefore, dust may block the lens when the high-definition camera is running for a long time, which will lead to inaccurate data collection. Attached Figure Description

[0027] The track 400 is set on the upper wall of the platform 100 and consists of a right-angled side and an inclined side.

[0028] The rotating shaft of the control plate 500 is rotatably mounted on the upper wall of the platform 100 via a connecting rod. A worm spring is provided between the rotating shaft of the control plate 500 and the connecting rod. Under the action of the worm spring, the control plate 500 always has a driving force to rotate clockwise.

[0029] The rotating device 600 is rotatably mounted on the upper wall of the control plate 500 via a connecting rod.

[0030] The flow guiding device 700 is mounted on the upper wall of the control plate 500 via a connecting rod.

[0031] The acquisition device 800 is installed on the upper wall of the platform 100.

[0032] like Figure 2 As shown, the drive device 200 includes: a motor 210 and a screw rod 220.

[0033] The motor 210 is mounted on the upper wall of the platform 100 via a connecting rod.

[0034] The screw rod 220 is mounted on the drive shaft of the motor 210, and the two rotate in the same direction.

[0035] like Figure 3 As shown, the moving device 300 includes: a moving plate 310, a driving block 320, and a round rod 330.

[0036] The movable plate 310 engages with the screw rod 220 and is able to move within a track on the upper wall of the platform 100 under its drive.

[0037] The drive block 320 is movably mounted in the slide rail of the moving plate 310.

[0038] The number of round rods 330 is two, one above the other, arranged on the side of the drive block 320. The two round rods 330 are always in contact with the track 400 and are located on the upper and lower sides of the track 400, and their height is adjusted by the track 400. The upper round rod 330 is provided with a top rod 340 on the side near the motor 210. Under the action of the top rod 340, the round rod 330 can quickly come into contact with the cylindrical battery 900.

[0039] like Figure 4 As shown, the track 400 includes: a smooth track 410 and an inclined track 420.

[0040] One end of the smooth track 410 is set on the upper wall of the platform 100 via a connecting rod, and the other end is connected to the inclined track 420. The smooth track 410 is set parallel to the platform 100.

[0041] One end of the inclined track 420 is inclinedly set on the upper wall of the platform 100, and the other end is connected to the smooth track 410.

[0042] like Figure 3-5 As shown, the rotating device 600 includes: a rotating block 610, a spiral rod 620, an elastic telescopic rod 630, a one-way rotating bearing 640, and a positioning block 650.

[0043] The rotating block 610 is rotatably mounted on the upper wall of the control plate 500 via a connecting rod.

[0044] The second helical rod 620 is mounted on the elastic telescopic rod 630 and can engage with the one-way rotating bearing 640.

[0045] The elastic telescopic rod 630 is mounted on the upper wall of the control plate 500 via a connecting rod, and the interior of the elastic telescopic rod 630 is provided with a compression spring that keeps the spiral rod 620 extending outward.

[0046] The one-way rotating bearing 640 is mounted on the rotating block 610. In a specific implementation, the movement of the helical rod 620 toward the elastic telescopic rod 630 can drive the rotating block 610 to rotate by driving the one-way rotating bearing 640 to rotate. In the opposite direction, it cannot drive the rotating block 610 to rotate.

[0047] The positioning block 650 is set on the upper wall of the platform 100 and located below the control plate 500. The positioning block 650 mainly serves to limit the maximum rotation angle of the control plate 500. Under the action of the positioning block 650, when the control plate 500 rotates clockwise and abuts against the positioning block 650, it just maintains a horizontal position.

[0048] like Figure 4-5 As shown, the guiding device 700 includes: guide plate 1 710, guide plate 2 720, cleaning block 1 730, cleaning block 2 740, abrasive block 750, balance bar 760, and guide plate 3 770.

[0049] The first guide plate 710 is disposed on both sides of the second guide plate 720, and an opening is provided on the first guide plate 710 for the cylindrical battery 900 to fall.

[0050] The second guide plate 720 is semi-circular and is mounted on the upper wall of the control plate 500 via a connecting rod. An opening is provided on the second guide plate 720.

[0051] The cleaning block 730 is set in Figure 5 The cleaning block 730 is located below the right camera 830 when the guide plate 710 is in a horizontal position.

[0052] The cleaning block 2 740 is set in Figure 5 The cleaning block 740 is located above the left-side guide plate 710 when the guide plate 710 is in a horizontal state. The cleaning block 740 is right-angled, and its vertical edge can contact and clean the camera 820 during implementation.

[0053] The abrasive block 750 is rotatably disposed in the opening of the guide plate 720 via a connecting rod. The upper and lower sides of the abrasive block 750 can contact the surfaces of the cylindrical battery 900 and the rotating block 610, mainly serving as a transmission mechanism. Furthermore, the abrasive texture on its surface can increase friction.

[0054] There are two balance bars 760, which are rotatably mounted on the second guide plate 720. The two balance bars 760 are located on both sides of the inner surface of the second guide plate 720, and play an auxiliary role in rotating the cylindrical battery 900 during specific implementation.

[0055] The guide plate 3 770 is located on the side of the guide plate 2 720, and it is provided with an inclined slide that can guide the cylindrical battery 900 during its descent.

[0056] like Figure 3-4 As shown, the acquisition device 800 includes: a support rod 810, a first camera 820, and a second camera 830.

[0057] The support rod 810 is vertically mounted on the upper wall of the platform 100.

[0058] The camera 820 is mounted on the support rod 810 and located next to the side of the cylindrical battery 900 to collect information.

[0059] The number of cameras 830 is two, which are mounted on the support rod 810 via a connecting rod and located at both ends of the cylindrical battery 900 to collect information from both ends.

[0060] Working principle of this invention:

[0061] When the operator needs to perform surface screening on the cylindrical battery 900, the operator first places the cylindrical battery 900 on the guide plate 720. Then, the motor 210 drives the spiral rod 220 to rotate, causing the moving plate 310 to move in the direction of the motor 210. The round rod 330 set on the drive block 320 inside the moving plate 310 moves along with it. During the movement, the round rod 330 located below the track 400 will collide with the spiral rod 620 and drive it to move in the direction of the elastic telescopic rod 630. The movement of the spiral rod 620 drives the one-way rotating bearing 640 to rotate, thereby driving the rotating block 610 to rotate. The rotation of the rotating block 610 drives the abrasive block 750 to rotate, thereby driving the cylindrical battery 900 to rotate so that various areas on its side are captured by the camera 820.

[0062] After the cylindrical battery 900 has finished rotating and both its side and end areas have been collected, it can be classified under the control of an external controller. When the collection result shows that the cylindrical battery 900 is without problems, the motor 210 drives the screw rod 220 to rotate, which in turn moves the moving plate 310 and controls the upper round rod 330 to move toward the cylindrical battery 900 on the smooth track 410. The top rod 340 on the upper round rod 330 will collide with the cylindrical battery 900 and push the cylindrical battery 900 toward the guide plate 770 below the cleaning block 730 and finally slide down the slide on the guide plate 770 into the external collection tank.

[0063] When the collected result is a problematic cylindrical battery 900, the round rod 330 moves in the opposite direction and moves down along the inclined edge of the inclined track 420. During the downward movement, under the weight of the round rod 330 itself, the guide plate 710 at the bottom of the cleaning block 2 740 below the round rod 330 will drive the control plate 500 to tilt and rotate downward together. The tilting and rotation of the control plate 500 will drive the guide plate 2 720 to tilt and rotate together. The cylindrical battery 900 located in the guide plate 2 720 will then move towards the opening of the guide plate 1 710 at the bottom of the cleaning block 2 740 under its own gravity, and slide down into the external collection tank to complete the classification of the cylindrical battery 900.

[0064] Driven by motor 210 and guided by track 400, the cylindrical battery 900 can be moved in different directions to fall through the opening of guide plate 1 710 and the slide of guide plate 3 770 to complete the collection. At the same time, the guide plate 1 710 at the bottom of cleaning block 2 740 tilts downward, which will cause the two cameras 2 830 to contact the cleaning blocks 1 730 and 2 740 next to them respectively to complete the cleaning of the cameras 2 830. As the collection continues, the lens can also be cleaned in an orderly manner. This avoids the dust that may exist on the surface of the battery. Therefore, dust may block the lens when the high-definition camera is running for a long time, which will lead to inaccurate information collection.
