The feeding mechanism is connected to the discharge end of the conveying mechanism.

[0006] By adopting the above technical solution, the material conveying mechanism sequentially transports the LED brackets to be inspected to the inspection mechanism and the marking mechanism for visual inspection and marking, respectively.

[0008] By adopting the above technical solution, the lifting device is controlled to drive the material box to rise, so that the push plate can push each layer of LED bracket in the material box to move from the material box to the belt conveyor, which greatly improves the feeding efficiency of LED bracket.

[0009] Preferably, the material conveying mechanism also has a limiting device and a lifting device.

The inspection mechanism can perform visual inspection on the LED bracket at the inspection position, and the lifting device lifts the LED bracket to the inspection position.

[0010] By adopting the above technical solution, the LED bracket to be inspected is stopped by the limiting device, which makes it easier for the subsequent lifting device to lift the LED bracket to the inspection position for appearance inspection.

[0018] By adopting the above technical solution, when the LED bracket moves to the end of the belt conveyor, the push rod is driven by the lateral movement component to move along the moving direction of the LED bracket, pushing the LED bracket away from the belt conveyor and into the unloading mechanism.

[0019] Preferably, the detection mechanism includes a three-axis translation device and a visual detection device connected to the three-axis translation device.

[0036] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0037] In traditional LED bracket appearance inspection, visual inspection and marking are performed by different and non-interoperable devices. Therefore, a person or robot needs to transfer the visually inspected LED bracket to the marking device for defect marking. Since the transfer of LED bracket takes a long time, the efficiency of LED bracket appearance inspection cannot be improved and the inspection cost is high.

[0038] Based on this, this application proposes an LED bracket appearance inspection device. The LED bracket appearance inspection device is equipped with a material conveying mechanism 2, which sequentially transports the LED brackets to be inspected to the inspection mechanism 4 and the marking mechanism 5 for visual inspection and marking, respectively. There is no need for manual transfer of LED brackets, which greatly improves the inspection efficiency of LED brackets.

[0039] The specific structure of the LED bracket appearance inspection equipment of this application will be described in detail below.

[0040] In one aspect of this disclosure, an LED bracket appearance inspection device is provided, such as... Figure 1 As shown, it includes a feeding mechanism 1, a conveying mechanism 2, an inspection mechanism 4, a marking mechanism 5, and an unloading mechanism 3. The feeding mechanism 1 supplies the LED brackets to be inspected to the conveying mechanism 2. The conveying mechanism 2 sequentially conveys the LED brackets to be inspected to the inspection mechanism 4 and the marking mechanism 5 for visual inspection and marking, respectively. After the appearance inspection is completed, the LED brackets are sent by the conveying mechanism 2 to the unloading mechanism 3 to complete the unloading. The whole process does not require manual transfer of the LED brackets, which greatly improves the inspection efficiency of the LED brackets.

[0041] In one example, the feeding mechanism 1 has a transverse movement device 13, a push plate 14 and a lifting device 12. The lifting device 12 is configured to drive the LED bracket to rise. The push plate 14 is connected to the transverse movement device 13. The transverse movement device 13 drives the push plate 14 to push the LED bracket to move horizontally synchronously, so that the LED bracket enters the feeding mechanism 2.

[0042] Optional, such as Figure 1 As shown, the lifting device 12 has a material carrier 11, on which a material box 15 is provided. Multiple layers of LED brackets are stacked in the material box 15 from top to bottom. The transverse moving device 13 drives the push plate 14 to push the LED brackets in the material box 15 from the material box 15 to the conveying mechanism 2. With this design, by controlling the lifting device 12 to lift the material box 15, the push plate 14 can push each layer of LED brackets in the material box 15 from the material box 15 to the belt conveyor 23. Since the material box 15 can store a large number of LED brackets and the lifting device 12 has multiple material carriers 11, the feeding mechanism 1 can supply LED brackets to the conveying mechanism 2 for a long time after being fully loaded with LED brackets, without the need for frequent shutdowns to feed material to the feeding mechanism 1, which greatly improves the feeding efficiency of LED brackets.

[0043] In one example, the conveying mechanism 2 has a belt conveyor 23 configured to convey LED brackets. The lateral movement device 13 drives the push plate 14 to push the LED brackets to move laterally, so that the LED brackets move onto the belt conveyor 23. Therefore, the feeding end of the conveying mechanism 2 is connected to the feeding mechanism 1.

[0044] Optional, such as Figure 1 , Figure 3 and Figure 6As shown, the conveying mechanism 2 also has a limiting device 28 and a lifting device 26. The lifting device 26 is located upstream of the limiting device 28 in the conveying direction of the belt conveyor 23. The limiting device 28 is configured to prevent the belt conveyor 23 from continuing to move the LED bracket. The lifting device 26 is configured to lift the LED bracket and separate it from the belt conveyor 23 when the limiting device 28 stops the LED bracket. The detection mechanism 4 can perform visual inspection on the LED bracket at the detection position. The lifting device 26 lifts the LED bracket to the detection position. With this design, the limiting device 28 stops the LED bracket to be inspected, making it easier for the lifting device 26 to lift the LED bracket to the detection position for visual inspection. In this way, while visual inspection is being performed, the belt conveyor 23 continues to convey the LED bracket, improving the overall online inspection efficiency of the LED bracket.

[0045] Optional, such as Figures 1-6 As shown, the material conveying mechanism 2 also has a pair of parallel side plates 21 spaced apart. The belt conveyor 23 is located between the pair of side plates 21. The pair of side plates 21 are connected to a spacing adjustment component 22. The spacing adjustment component 22 is configured to adjust the spacing between the pair of side plates 21 to adapt to belt conveyors 23 of different widths, thereby conveying LED brackets of different sizes.

[0046] Specifically, the structure of the belt conveyor 23 is as follows: Figure 7 As shown, it includes a pulley 231 mounted on a side plate 21 and a conveyor belt 232 sleeved on the pulley 231, as well as a drive component 233 that drives the pulley 231 to rotate. The lateral movement device 13 drives the push plate 14 to push the LED bracket to move laterally so that the LED bracket moves onto the conveyor belt 232.

[0047] In practical implementation, the belt conveyor 23 can be configured as one for long-distance transport of LED brackets, or multiple conveyors can be configured for relay transport, for example... Figures 1-7 The three belt conveyors 23 shown are set up independently, which is more convenient for LED bracket transportation compared to setting up a single conveyor. For example, loading, visual inspection, marking, and unloading of LED brackets are carried out by different belt conveyors 23, making LED bracket inspection operations more flexible and helping to further improve the inspection efficiency of LED brackets.

[0048] Specifically, such as Figure 7 As shown, the top material device 26 includes a second lifting component 262 and a lifting plate 263 connected to the lifting end of the second lifting component 262. The lifting plate 263 is located between a pair of side plates 21. The second lifting component 262 is mounted on a mounting base 261. The mounting base 261 is fixedly set. The LED bracket can be lifted by controlling the movement of the second lifting component 262.

[0049] Optionally, the material conveying mechanism 2 also has a clamping device 27 and a limiting device 24. The limiting device 24 is located upstream of the top material device 26 in the conveying direction of the belt conveyor 23. The limiting device 24 is configured to block the LED bracket that is about to enter the top material device 26, so as to prevent the LED bracket from moving into the active area of ​​the top material device 26 and affecting the operation of the top material device 26.

[0050] Specifically, such as Figure 7 As shown, the limiting device 24 includes a lifting component 242 and a limiting member 241 connected to the lifting end of the lifting component 242. The limiting member 241 is located between a pair of side plates 21. The lifting component 242 is fixedly installed. The LED bracket can be stopped by controlling the movement of the lifting component 242.

[0051] In one example, such as Figure 7 As shown, the limiting device 24 and the limiting device 28 have the same structure.

[0052] The clamping device 27 is configured to clamp and fix the LED bracket at the detection position, ensuring that the LED bracket does not shake during the detection process and that the visual inspection is completed smoothly.

[0053] Specifically, such as Figure 4 As shown, the clamping device 27 includes a lifting component 271, a sliding column 273, a slider 275, and an elastic element 274. The lifting component 271 is fixedly installed, and a roller 278 is installed on its upper lifting part. The sliding column 273 is fixedly connected to the side plate 21, and the slider 275 is slidably connected to the sliding column 273. The slider 275 is fixedly connected to a pressure block 277 via a connecting rod 276. The pressure block 277 is located on the inner side of the side plate 21. The slider 275 slides along the sliding column 273, causing the pressure block 277 to separate from the side plate 21 and enter between the pair of side plates 21 to clamp and fix the LED bracket at the detection position. The slider 275 is provided with a receiving groove 279. The roller 278 rises into the receiving groove 279 and pushes the slider 275 to slide along the sliding column 273. One end of the elastic element 274 is fixedly installed, for example... Figure 4As shown, one end of the elastic element 274 is fixedly installed on the sliding column 273 by a connecting piece 272. The other end of the elastic element 274 is connected to a slider 275. The slider 275 slides along the sliding column 273, causing the elastic element 274 to undergo elastic deformation. For example, the roller 278 rises into the receiving groove 279 and pushes the slider 275 to slide along the sliding column 273, compressing the elastic element 274. This causes the pressure block 277 to leave between the pair of side plates 21 and contact the side plates 21. At this time, the pressure block 277 does not affect the lifting and lowering of the LED bracket. When the roller 278 descends and leaves the receiving groove 279, the compressed elastic element 274 pushes the slider 275 to slide in the opposite direction along the sliding column 273, causing the pressure block 277 to separate from the side plates 21 and enter between the pair of side plates 21 to clamp and fix the LED bracket at the detection position. It can be seen that by adopting the above technical solution, the lifting component 271 controls the movement of the slider 275 to drive the pressure block 277 into the pair of side plates 21.

[0054] The detection mechanism 4 and the marking mechanism 5 are arranged sequentially beside the conveying mechanism 2 along the conveying direction of the conveying mechanism 2. The detection mechanism 4 is configured to perform appearance inspection on the LED brackets sent by the conveying mechanism 2, and the marking mechanism 5 is configured to mark surface defects on the LED brackets. The unloading mechanism 3 is connected to the discharge end of the conveying mechanism 2. The LED brackets that have completed appearance inspection are sent by the conveying mechanism 2 to the unloading mechanism 3 to complete the unloading.

[0055] In one example, such as Figure 1 and Figure 3 As shown, the detection mechanism 4 includes a three-axis translation device 41 and a vision detection device 42 connected to the three-axis translation device 41. By adopting the above technical solution, the vision detection device 42 is moved along the XYZ three axes by the three-axis translation device 41 to complete the vision detection of all areas of the entire LED bracket.

[0056] In one example, such as Figure 1 , Figure 3 , Figure 6 , Figure 8 , Figure 9 As shown, the marking mechanism 5 includes a laser marking device 51, a dust adsorption device 52, and a visual positioning device 54. The visual positioning device 54 is configured to locate the position of surface defects on the LED bracket, so that the laser marking device 51 can blacken the surface defects on the LED bracket according to the positioning information obtained by the visual positioning device 54. The dust adsorption device 52 is configured to absorb the dust generated during the blackening process to prevent dust from polluting the air.

[0057] Optional, such as Figure 8As shown, the visual positioning device 54 can also locate surface defects on the LED bracket with the help of the reflector 53. At this time, the light emitted by the visual positioning device 54 is reflected by the reflector 53 and shines downward onto the LED bracket.

[0058] In one example, such as Figure 1 and Figure 6 As shown, the unloading mechanism 3 and the loading mechanism 1 have the same structure. With this design, the unloading mechanism 3 can store a large number of LED brackets at one time, without having to frequently stop the machine to wait for the unloading mechanism 3 to move the fully loaded LED brackets away, which greatly improves the loading efficiency of LED brackets.

[0059] Correspondingly, such as Figure 1 , Figure 2 , Figure 5 and Figure 10 As shown, the material conveying mechanism 2 also has a pushing device 29, which is located at the discharge end of the belt conveyor 23. The pushing device 29 includes a lateral moving component 291, a second lifting component 293, and a push rod 295. The lateral moving component 291 is fixedly installed. The second lifting component 293 is connected to the movable end of the lateral moving component 291, and the push rod 295 is connected to the movable end of the second lifting component 293. The second lifting component 293 is configured to drive the push rod 295 to rise and fall, so that one end of the push rod 295 extends into / out of the movement path of the LED bracket. The lateral moving component 291 is configured to drive the push rod 295 to move along the movement direction of the LED bracket, pushing the LED bracket away from the belt conveyor 23. By adopting the above technical solution, when the LED bracket moves to the end of the belt conveyor 23, the lateral moving component 291 drives the push rod 295 to move along the movement direction of the LED bracket, pushing the LED bracket away from the belt conveyor 23 and into the material box 15 of the unloading mechanism 3.

[0060] Optional, such as Figure 10 As shown, the movable end of the transverse component 291 is connected to the transverse seat 292, and the lifting component 293 is installed on the transverse seat 292. The transverse seat 292 is provided with a guide post 294, which is slidably connected to the push rod 295. This design can improve the stability of the push rod 295 movement.

[0061] In one example, such as Figure 5 As shown, the discharge end of the conveying mechanism 2 is equipped with a second positioning detection component 20. With this design, the pusher device 29 can be controlled to operate according to the detection signal of the second positioning detection component 20.
