[0032] like Figures 1 to 12As shown, the present invention discloses an LED module beating device, which includes a base 1, and a module conveying device 2, a module positioning device 3 and a module beating device 4 installed on the base 1; wherein, the module conveying device 2 is used to convey the LED module and can convey the LED module to the beating station; the module positioning device 3 is used to position the LED module conveyed to the beating station; the module beating device 4 is used to beat the LED module at the beating station.

[0033] When the LED module beating device of the present invention is in use, the module conveying device 2 first conveys the LED module to the beating station, and then the module positioning device 3 positions the LED module conveyed to the beating station to prevent the LED module from shifting, and then the module beating device 4 beats the LED module at the beating station, and the LED module after beating can be subsequently sent to the detection station to detect whether the LED module after beating is normal. As can be seen from the foregoing, the LED module device of the present invention can realize automatic beating of the LED module, reduce labor costs, avoid the problem of omissions in manual beating, and the module beating device 4 can control the beating force of the LED module to ensure the consistency of the beating force.

[0034] In the embodiment of the present invention, the base 1 may be provided with an in-position detection sensor 9 corresponding to the tapping station, so that the module conveying device 2 can accurately convey the LED module to the tapping station. The in-position detection sensor 9 may be a reflective photoelectric switch.

[0035] In the embodiment of the present invention, the module conveying device 2 includes two first belt conveying devices 21 that are arranged opposite to each other and at intervals. The first belts 211 of the two first belt conveying devices 21 can support the two ends of the LED module and drive the LED module to move. Each first belt conveying device 21 is provided with a first stopper 212 adjacent to the first belt 211 of the first belt conveying device 21. One side of the first stopper 212 forms a first stop surface 2121 that is higher than the first belt 211. The first stop surface 2121 can limit the edge of the LED module to prevent the LED module from falling from the two first belt conveying devices 21.

[0036] In an embodiment of the present invention, the module conveying device 2 may further include a conveying adjustment device 22 for driving the two first belt conveying devices 21 to move relative to each other, and the conveying adjustment device 22 drives the two first belt conveying devices 21 to move relative to each other and adjusts the spacing between the two first belt conveying devices 21, so that the module conveying device 2 can adapt to LED modules of different sizes. Wherein, the conveying adjustment device 22 includes an adjustment guide rail 221, a bidirectional screw rod 222, and an adjustment motor 223, wherein the adjustment guide rail 221 is fixedly arranged on the machine base 1 and the adjustment guide rail 221 is slidably connected with the two first belt conveying devices 21, the bidirectional screw rod 222 is rotatably arranged on the machine base 1 and the two opposite threaded sections of the bidirectional screw rod 222 are respectively screwed with the two first belt conveying devices 211, the adjustment motor 223 is in transmission cooperation with the bidirectional screw rod 222 and drives the bidirectional screw rod 222 to rotate, and the adjustment motor 223 drives the bidirectional screw rod 222 to rotate to drive the two first belt conveying devices 21 to move toward and away from each other.

[0037] In an embodiment of the present invention, the module positioning device 3 includes a positioning seat 31 arranged between two first belt conveyors 21 and a positioning and lifting driving device 32 for driving the positioning seat 31 to rise and fall. The positioning and lifting driving device 32 is installed on the machine base 1, and the positioning and lifting driving device 32 can be a cylinder; when the module conveyor 2 conveys the LED module to the beating station, the positioning and lifting driving device 32 drives the positioning seat 31 to rise and support and position the LED module; after the module beating device 4 beats the LED module, the positioning and lifting driving device 32 drives the positioning seat 31 to descend so that the LED module falls to the two first belt conveyors 21 of the module conveyor 2, so that the module conveyor 2 continues to convey the LED module. Among them, the positioning seat 31 can have a guide rod 311 that slides up and down with the machine base 1 so that the positioning seat 31 can rise and fall smoothly.

[0038] In an embodiment of the present invention, the positioning seat 31 is equipped with at least one positioning clamping device 33, the positioning clamping device 33 includes two opposite clamping seats 331 and a positioning clamping driving device 332 driving the two clamping seats 331 to move relative to each other, the positioning clamping driving device 332 is installed on the positioning seat 31, and the positioning clamping driving device 332 can be a cylinder connected to the two clamping seats 331 respectively. When the LED module is transported to the beating station, the positioning lifting driving device 32 drives the positioning seat 31 to rise and support and position the LED module. At the same time, the positioning clamping device 33 drives the two clamping seats 331 to move toward each other and clamp the LED module, thereby effectively ensuring that the LED module will not shift during beating; after the module beating device 4 beats the LED module, the positioning clamping device 33 first drives the two clamping seats 331 to move back to each other and release the LED module, and then the positioning lifting driving device 32 drives the positioning seat 31 to descend so that the LED module falls to the two first belt conveyors 21 of the module conveying device 2. There can be multiple positioning and clamping devices 33 to accommodate LED modules of different sizes. The moving direction of the clamping seat 331 is parallel to the conveying direction of the module conveying device 2 to avoid mutual interference between the clamping seat 331 and the module conveying device 2.

[0039] In an embodiment of the present invention, the module beating device 4 includes at least one beating component 41, and the beating component 41 includes a beating seat 411 arranged above the module positioning device 3 and a beating lifting drive device 412 for driving the beating seat 411 to rise and fall, and the beating lifting drive device 412 can be a cylinder; when the module beating device 4 beats the LED module, the beating lifting drive device 412 drives the beating seat 411 to rise and fall quickly so that the beating seat 411 beats the LED module. Among them, the number of beating components 41 can be multiple, so that the beating area of ​​the entire module beating device 4 is large, and the beating rhythms of each beating component 41 can be different, so that the comprehensiveness of the beating of the LED module can be improved.

[0040] In an embodiment of the present invention, the slapping seat 411 may include a fixed seat 4111, a movable seat 4112 that slides up and down with the fixed seat 4111 and is located below the fixed seat 4111, and a buffer spring 4113 arranged between the fixed seat 4111 and the movable seat 4112, and the fixed seat 4111 is connected to the slapping lifting drive device 412; such an arrangement allows the movable seat 4112 to move and the buffer spring 4113 to absorb the reaction force of the LED module when the slapping seat 4111 slaps the LED module, thereby avoiding excessive slapping force on the LED module and causing damage to the LED module. Among them, the movable seat 4112 may have a sliding rod 4114 that slides with the fixed seat 4111, and the buffer spring 4113 is sleeved on the sliding rod 4114 to prevent the buffer spring 4113 from falling off. In addition, the bottom side of the beating seat 411 (i.e., the bottom side of the movable seat 4112) may be equipped with an elastic pad 413, which may be made of silicone material. The elastic pad 413 also has a buffering effect and can also prevent damage to the LED module caused by excessive beating force.

Since the module transport device 5 is lower than the module conveying device 2, the LED module falls from the module conveying device 2 to the module transport device 5, causing the LED module to vibrate. In this way, a simulated beating operation can be performed on the LED module, thereby improving the comprehensiveness of the beating of the LED module.

[0043] In the embodiment of the present invention, the module transport device 5 includes two second belt conveyors 51 that are arranged oppositely and at intervals. The two second belt conveyors 51 are provided with an upwardly convex guide plate 513 at one end close to the module conveyor 2.

In addition, each second belt conveyor 51 is provided with a second stopper 512 adjacent to the second belt 511 of the second belt conveyor 51, and a second stop surface 5121 higher than the second belt 511 is formed on one side of the second stopper 512. The second stop surface 5121 can limit the edge of the LED module to prevent the LED module from falling from the two second belt conveyors 51.

[0044] In an embodiment of the present invention, the module transport device 5 may further include a mounting base 52, the mounting base 52 is provided with a mounting rail 521, and the two second belt conveyor devices 51 are respectively connected to the mounting rail 521 through mounting clamps 53, so that by adjusting the connection position of the mounting clamp 53 and the mounting rail 521, the distance between the two second belt conveyor devices 51 can be changed, thereby adapting to LED modules of different sizes.

[0045] In an embodiment of the present invention, the LED module beating device of the present invention may also include a height adjustment device 6 for driving the module transport device 5 to rise and fall, so as to adjust the height of the LED module from the module conveying device 2 to the module transport device 5, so as to facilitate testing at different heights.
