Technical Field
[0001] This utility model relates to the field of LED testing technology, specifically to a discharge anti-jamming device and an LED testing system. Background Technology
[0002] Existing LED board feeding devices often cause damage to LED boards due to jamming during the feeding process, resulting in continuous hard compression. Existing devices cannot automatically avoid jamming and require additional sensor detection, which is costly. Therefore, there is an urgent need for a feeding anti-jamming device and an LED testing system to solve the above problems. Utility Model Content
[0003] In view of this, an automatic obstacle avoidance, low cost and simple structure discharge anti-jamming device and LED testing system are provided.
[0004] A discharge anti-jamming device for pushing LED boards back into a material box includes an anti-jamming component, a connecting plate, and a cylinder assembly. The anti-jamming component is connected to the connecting plate via a rotating shaft. The connecting plate has an upper and a lower contact portion at its front end. The anti-jamming component includes an upper magnetic attraction portion and a lower magnetic attraction portion located at both ends. The upper and lower magnetic attraction portions can respectively magnetically attract the upper and lower contact portions of the connecting plate. The anti-jamming component is mounted on the connecting plate via a rotating shaft, which is located between the upper and lower magnetic attraction portions. The position between the suction parts; the upper magnetic suction part and the lower magnetic suction part form a predetermined angle so that when the lower magnetic suction part rotates freely to avoid the surface of the LED board, the upper magnetic suction part can approach or adhere to the upper contact part of the connecting plate. The connecting plate is installed on the cylinder assembly. The cylinder assembly drives the anti-jamming component to move so that the anti-jamming component pushes the LED board back into the material box. When the LED board is jammed, the lower magnetic suction part of the anti-jamming component can rotate around the rotating shaft to a non-contact position above the LED board.
[0005] Furthermore, the connecting plate includes a connecting part, a fitting part, and a rotating shaft through hole. The connecting part is installed on the cylinder assembly. The fitting part includes an upper fitting part and a lower fitting part. The fitting part is connected to the connecting part at an angle. The rotating shaft through hole is provided at the corner of the fitting part and the connecting part, and the rotating shaft is disposed in the rotating shaft through hole.
[0006] Furthermore, the fitting part and the connecting part are integrally formed or combined into one structure.
[0007] Furthermore, the anti-jamming component also includes a pushing part, and the discharge anti-jamming device also includes a magnet. The pushing part is fixed to the lower magnetic suction part, and there is an angle between the upper magnetic suction part and the lower magnetic suction part. Both the upper magnetic suction part and the lower magnetic suction part are provided with magnetic grooves to install the magnet. The lower magnetic suction part is magnetically attracted to the lower bonding part. When the LED board jams, the anti-jamming component rotates relative to the connecting plate through the rotating shaft until the upper magnetic suction part is magnetically attracted to the upper bonding part, and the lower magnetic suction part and the pushing part rotate synchronously to the top of the LED board.
[0008] Furthermore, the lower magnetic suction part is fixed to the upper part of the pusher part, and the lower part of the pusher part is used to push the LED board. The lower part of the pusher part is opposite to the LED board, and the lower pusher surface of the pusher part is parallel and spaced apart from the pusher surface of the LED board.
[0009] Furthermore, the pushing part, the lower magnetic suction part, and the upper magnetic suction part are integrally formed or combined into one structure.
[0010] Furthermore, the connecting plate is a magnetic material.
[0011] An LED testing system includes an LED board clamping device, an X-axis moving component, a Y-axis moving component, and a discharge anti-jamming device. The LED board clamping device is connected to the X-axis moving component and the Y-axis moving component, and the discharge anti-jamming device is the aforementioned discharge anti-jamming device.
[0012] Compared with the prior art, the present invention has at least the following beneficial effects:
[0013] This anti-jamming device for material discharge has an upper magnetic suction part and a lower magnetic suction part. When material jams, the suction surface is switched by rotating the shaft, so that the pushing part can automatically rotate around the shaft to a non-contact position above the LED board, effectively avoiding rigid collisions and significantly reducing the risk of damage to the LED board when material jams. Compared with traditional anti-jamming devices, this magnetic rotatable anti-jamming structure does not require the use of sensors. It only requires the anti-jamming part to cooperate with the connecting plate, which is simple in structure and low in cost. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 5 This illustration shows an embodiment of the present invention providing a discharge anti-jamming device for pushing an LED board 2 back into a material box 1. The device includes an anti-jamming component 6, a connecting plate 3, and a cylinder assembly 4. The anti-jamming component 6 is connected to the connecting plate 3 via a rotating shaft 5. The connecting plate 3 has an upper fitting portion 9 and a lower fitting portion 10 at its front end. The anti-jamming component 6 includes an upper magnetic attraction portion 12 and a lower magnetic attraction portion 13 located at both ends. The upper magnetic attraction portion 12 and the lower magnetic attraction portion 13 can respectively magnetically attract the upper fitting portion 9 and the lower fitting portion 10 of the connecting plate 3. The anti-jamming component 6 is mounted on the connecting plate 3 via the rotating shaft 5, which is located at the... The position between the upper magnetic suction part 12 and the lower magnetic suction part 13 is described; the upper magnetic suction part 12 and the lower magnetic suction part 13 form a predetermined angle so that when the lower magnetic suction part 13 rotates freely to avoid the surface of the LED board 2, the upper magnetic suction part 12 can approach or adhere to the upper contact part 9 of the connecting plate 3. The connecting plate 3 is installed on the cylinder assembly 4. The cylinder assembly 4 drives the anti-jamming member 6 to move so that the anti-jamming member 6 pushes the LED board 2 back to the material box 1. When the LED board 2 is jammed, the lower magnetic suction part 13 of the anti-jamming member 6 can rotate around the rotating shaft 5 to a non-contact position above the LED board 2.
[0023] Specifically, the connecting plate 3 includes a connecting part 8, a fitting part, and a rotating shaft through hole 18. The connecting part 8 is installed on the cylinder assembly 4. The fitting part includes an upper fitting part 9 and a lower fitting part 10. The fitting part is connected to the connecting part 8 at an angle. The rotating shaft through hole 18 is provided at the corner of the fitting part and the connecting part 8. The rotating shaft 5 is disposed in the rotating shaft through hole 18.
[0024] More specifically, the fitting part and the connecting part 8 are integrally formed or combined into one structure.
[0025] Specifically, the anti-jamming component 6 further includes a pushing part 11, and the discharge anti-jamming device further includes a magnet 7. The pushing part 11 is fixed to the lower magnetic suction part 13. The upper magnetic suction part 12 and the lower magnetic suction part 13 have an included angle. Both the upper magnetic suction part 12 and the lower magnetic suction part 13 are provided with magnetic grooves 14 to install the magnet 7. The lower magnetic suction part 13 is magnetically attracted to the lower bonding part 10. When the LED board 2 is jammed, the anti-jamming component 6 rotates relative to the connecting plate 3 through the rotating shaft 5 until the upper magnetic suction part 12 is magnetically attracted to the upper bonding part 9. The lower magnetic suction part 13 and the pushing part 11 rotate synchronously to the top of the LED board 2. More specifically, providing a magnetic groove 14 and installing the magnet 7 in the magnetic groove 14 is one preferred embodiment. Alternatively, both the upper magnetic suction part 12 and the lower magnetic suction part 13 can be made of magnets, so that the upper magnetic suction part 12 and the lower magnetic suction part 13 are inherently magnetic.
[0026] In some specific embodiments, when the LED board 2 is jammed, the pushing part 11 is pushed by a reverse thrust. After overcoming the magnetic force, the pushing part 11 drives the lower magnetic suction part 13 to rotate and tilt up. The lower magnetic suction part 13 automatically separates from the lower bonding part 10, and the upper magnetic suction part 12 rotates synchronously around the rotating shaft 5 towards the upper bonding part 9. After rotation, under the action of magnetic force, the upper magnetic suction part 12 comes close to or is bonded to the upper bonding part 9. Finally, after the anti-jamming part 6 flips around the rotating shaft 5, it can be suspended in a non-contact position above the LED board 2. Therefore, during the process of the cylinder assembly 4 driving the connecting plate 3 to move, when the LED board 2 is jammed, the pushing part 11 will automatically flip upward. After flipping, within the stroke range of the cylinder assembly 4, the cylinder assembly 4 can only drive the pushing part 11 to move back and forth above the LED board 2 and no longer contact the LED board 2. This can effectively prevent the LED board 2 from being damaged by hard squeezing and reduce the damage rate when the LED board 2 is jammed.
[0027] More specifically, the lower magnetic suction part 13 is fixed to the upper part of the pusher part 11, the lower part of the pusher part 11 is used to push the LED board 2, the lower part of the pusher part 11 is opposite to the LED board 2, and the lower pusher surface of the pusher part 11 is parallel and spaced apart from the pusher surface of the LED board 2.
[0028] More specifically, the pusher part 11, the lower magnetic suction part 13, and the upper magnetic suction part 12 are integrally formed or combined into one structure.
[0029] Specifically, the connecting plate 3 is a magnetic attractor, and more specifically, the magnetic attractor can be made of silicon steel.
[0030] An LED testing system includes an LED board clamping device 15, an X-axis moving component 16, a Y-axis moving component 17, and a discharge anti-jamming device. The LED board clamping device 15 is connected to the X-axis moving component 16 and the Y-axis moving component 17, and the discharge anti-jamming device is the aforementioned discharge anti-jamming device.
[0031] In some specific embodiments, the X-axis moving component 16 and the Y-axis moving component 17 are both driven by servo motors to drive the lead screw module to control the LED board clamping device 15 to move along the X-axis and Y-axis. The LED board clamping device 15 fixes the LED board 2, so the LED board 2 can move along the X-axis and Y-axis until the surface to be pushed of the LED board 2 is opposite to and parallel to the lower pushing surface of the pushing part 11.
[0032] In summary, the anti-jamming component 6 of this discharge anti-jamming device is equipped with an upper magnetic suction part 12 and a lower magnetic suction part 13. When jamming occurs, the suction surface is switched by rotating the shaft 5, so that the pushing part 11 can automatically rotate around the shaft 5 to a non-contact position above the LED board 2, effectively avoiding rigid collisions and significantly reducing the risk of damage to the LED board 2 when jamming. Compared with traditional anti-jamming devices, this magnetic rotatable anti-jamming structure does not require the use of sensors, only the anti-jamming component 6 and the connecting plate 3 need to cooperate, which makes the structure simple and the cost low.
[0033] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
