[0022] The beneficial effects of the present invention are:

[0023] 1. During use, the distance between the lower barrel and the top surface of the base can be adjusted according to the thickness of the LED lamp beads, so that the distance is greater than the thickness of the lamp beads. When the bottom lamp bead slides to the top surface of the base, the intermittent feeding device can be used to push the bottom lamp bead toward the conveying detection device for electrostatic detection.

[0038] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figures 1 to 12 As shown, the device for detecting the antistatic ability of LED lamp beads according to an embodiment of the present invention includes a base 1, which can be placed on a desktop for use and provides a fixed foundation for subsequent structures. The top of the base 1 is provided with an intermittent feeding device 2, a feeding device 3, a conveying and detecting device 4, and a dividing device 5 from left to right.

[0040] The unloading device 3 includes an unloading vertical plate 6 fixedly mounted on the rear side of the top surface of the base 1, and a unloading barrel 7 located above the top surface of the base 1 and opened at both ends is installed on the front side of the unloading vertical plate 6 for sliding up and down. The unloading barrel 7 can adjust the distance between its bottom and the top surface of the base 1, and two lamp bead storage plates 8 with symmetrical front and rear positions are installed inside the unloading barrel 7 for sliding forward and backward. A plurality of pin slide grooves 9 are provided on the opposite sides of the two lamp bead storage plates 8, and a plurality of LED lamp beads 01 stacked up and down between the two lamp bead storage plates 8 are placed inside the unloading barrel 7. The LED lamp beads 01 inside the unloading barrel 7 can be placed manually, and the metal lead of the LED lamp beads 01 The pins 02 are placed in the corresponding pin chutes 9, and the distance between the two lamp bead storage plates 8 can be adjusted according to the width between the pins on both sides of the LED lamp bead 01, so that the metal pin ends of the LED lamp bead 01 can fit with the inner side of the pin chutes 9, so that multiple LED lamp beads 01 can slide along the pin chutes 9 to the bottom of the lower barrel 7 without being deflected inside the lower barrel 7. The multiple pin chutes 9 respectively provided on the two lamp bead storage plates 8 can use LED lamp beads 01 with multiple pins of different models. When in use, the distance between the lower barrel 7 and the top surface of the base 1 can be adjusted according to the thickness of the LED lamp bead 01, so that the distance is greater than the thickness of the lamp bead;

[0041] When the bottom LED lamp bead 01 slides to the top surface of the base 1, the intermittent feeding device 2 can push the bottom LED lamp bead 01 toward the conveying detection device 4 for electrostatic detection. After the intermittent feeding device 2 is reset, the upper lamp bead continues to slide downward. A gravity block can be placed on the top of the top LED lamp bead 01 so that the LED lamp bead 01 can slide downward smoothly. In conjunction with the intermittent feeding device 2, automatic and continuous electrostatic detection of multiple LED lamp beads 01 can be achieved.

[0042] The conveying detection device 4 includes a conveying trough 10 opened on the top of the base 1 and located on the right side of the unloading barrel 7. The left and right ends of the conveying trough 10 are rotatably installed with conveying wheels 11. A conveyor belt 12 is connected between the two conveying wheels 11. The conveying wheels 11 and the conveyor belt 12 can use a synchronous pulley set. The top surface of the base 1 is fixedly installed with a conveying vertical plate 13 located on the right side of the unloading vertical plate 6. The front side of the conveying vertical plate 13 is slidably installed with an "L"-shaped conveying adjustment plate 14. The bottom end of the conveying adjustment plate 14 is connected to a conveying buffer plate 15. The left and right sides of the conveying buffer plate 15 A buffer chute 16 is opened at each end, and a buffer slider 17 is installed in each of the buffer chute 16 for sliding up and down. A conveying buffer wheel 18 is rotatably installed on the front side of each of the buffer sliders 17. A conveying buffer belt 19 opposite to the conveyor belt 11 is connected between the two conveying buffer wheels 18. The conveying buffer wheel 18 and the conveying buffer belt 19 can use a synchronous pulley group. A buffer spring 20 is fixedly connected between each of the buffer sliders 17 and the top of the buffer chute 16. The conveying adjustment plate 14 can adjust its height above the base 1, thereby realizing the height adjustment of the conveying buffer belt 19, as shown in the attached figure. Figure 2 As shown, the conveyor belt 12 rotates clockwise, while the conveyor buffer belt 19 rotates counterclockwise;

[0043] During use, the height of the bottom surface of the conveying buffer belt 19 can be adjusted to be lower than the top surface of the LED lamp bead 01. When the intermittent feeding device 2 pushes the LED lamp bead 01 to the right, the LED lamp bead 01 can be pushed between the conveyor belt 12 and the conveyor buffer belt 19. Since the lowest surface of the conveying buffer belt 19 is lower than the top surface of the LED lamp bead 01, the LED lamp bead 01 can push up the conveying buffer wheel 18 on the left side of the conveying buffer plate 15, and the conveying buffer wheel 18 drives the buffer slider 17 to compress the conveying buffer spring 20 upward. The conveying buffer spring 20 can apply downward pressure to the LED lamp bead 01 through the conveying buffer wheel 18 and the conveying buffer belt 19, so that the conveyor belt 12 and the conveying buffer belt 19 can drive the LED lamp bead 01 to move to the right when the conveyor belt 12 and the conveying buffer belt 19 rotate. By adjusting the height of the conveying buffer belt 19, the conveying detection of LED lamp beads 01 of different thicknesses can be carried out;

[0044] The conveying detection device 4 also includes an electrode chute 21 opened on the top of the base 1 and located on the front and rear sides of the conveying trough 10. An electrode adjustment plate 22 with a "U"-shaped cross-section and an open end facing the conveying trough 10 is installed in each of the electrode chute 21 for sliding back and forth. The two electrode adjustment plates 22 can slide back and forth in the two electrode chutes 21 at the same time to adjust the distance between the two. A plurality of electrode springs 23 are fixedly installed on the top and bottom surfaces of each electrode adjustment plate 22. The other ends of the plurality of electrode springs 23 on the same side are fixedly connected to the same electrode sheet 24. The two electrode sheets 24 located in the same electrode adjustment plate 22 are connected to the electrode end of the same electrostatic power supply.

[0045] When in use, the two electrode adjustment plates 22 can be adjusted according to the width between the metal pins 02 on both sides of the LED lamp bead 01, so that the metal pins 02 on the front and rear sides of the LED lamp bead 01 can fit with the opposite surfaces inside the two electrode adjustment plates 22. When the intermittent feeding device 2 pushes the LED lamp bead 01 between the conveyor belt 12 and the conveyor buffer belt 19, the metal pins 02 on the front and rear sides of the LED lamp bead 01 enter the interior of the two electrode adjustment plates 22, and the metal pins 02 on the front and rear sides of the LED lamp bead 01 enter between the two electrode sheets 24 on the same side and are energized therewith, so that electrostatic voltage is passed into the LED lamp bead 01 for detection. The two electrode sheets 24 can clamp the metal pins 02 under the elastic force of the electrode spring 23, thereby avoiding the situation where the metal pins 02 and the electrode sheets 24 have a poor connection when the conveyor belt 12 and the conveyor buffer belt 19 drive the LED lamp bead 01 to move to the right.

[0046] An intelligent detection unit is installed on the base 1. When the LED lamp bead 01 is energized with electrostatic voltage, the intelligent detection unit can obtain feedback to determine the detection result of the anti-static ability of the LED lamp bead 01. When the LED lamp bead 01 moves to the rightmost end of the conveyor belt 12 and the conveyor buffer belt 19, the metal pins 02 on the front and rear sides are separated from the electrode sheet 24, and the detection is completed. At this time, the LED lamp bead reaches the top of the dividing device 5, and the dividing device 5 is connected to the intelligent detection unit. When the intelligent detection unit detects that the LED lamp bead 01 is of qualified quality, the dividing device 5 conveys the LED lamp bead 01 to the qualified area. If the LED lamp bead 01 is detected to be unqualified, the dividing device 5 conveys the LED lamp bead 01 to the unqualified area. Through the above structure, the problem of manual operation of picking up and installing LED lamp beads one by one in the prior art is solved, which is time-consuming and leads to low efficiency of manual detection.

[0047] like Figure 1 、 Figure 2 and Figure 4As shown, the intermittent feeding device 2 includes an intermittent feeding circular groove 25 opened on the top of the base 1 and located on the left side of the discharge barrel 7, an intermittent feeding disc 26 is rotatably installed in the intermittent feeding circular groove 25, an intermittent feeding ring 27 is fixedly installed on the top of the base 1 and located between the intermittent feeding disc 26 and the discharge barrel 7, an intermittent feeding push rod 28 is slidably installed in the intermittent discharge ring 27, an intermittent feeding plate 29 is fixedly connected to the left end of the intermittent discharge push rod 28, a feeding long groove 30 is passed through the intermittent feeding plate 29 from top to bottom, and an intermittent feeding pin 31 located in the feeding long groove 30 is fixedly installed at the edge of the top surface of the intermittent feeding disc 26;

[0048] A feeding motor slot 32 is provided in the middle of the bottom surface of the intermittent feeding circular slot 25. A feeding motor 33 connected to the intermittent feeding disc 26 is installed in the feeding motor slot 32. The feeding motor 33 is connected to a power supply and a controller.

[0049] During use, the controller starts the feeding motor 33 to drive the intermittent feeding disc 26 to rotate, causing the intermittent feeding pin 31 to move in a circular motion. When the intermittent feeding pin 31 moves in a circular motion, it slides with the feeding long groove 30, thereby driving the intermittent feeding plate 29 and the intermittent feeding push rod 28 to move left and right in the intermittent feeding ring 27, thereby achieving the effect of pushing the LED lamp bead 01 at the bottom of the discharge barrel 7 to the right to between the conveyor belt 12 and the conveyor buffer belt 19.

[0050] like Figure 3 As shown, the blanking vertical plate 6 is penetrated by blanking lifting grooves 34 in front and back, and a blanking slider 35 is installed in the blanking lifting groove 34 for sliding up and down. The blanking slider 35 is fixedly connected to the rear side of the blanking barrel 7, and a blanking screw 36 is rotatably installed in the blanking lifting groove 34, which penetrates the blanking slider 35 and is threadedly connected to it.

[0051] When in use, the blanking screw rod 36 is rotated to drive the blanking slider 35 to move up and down in the blanking lifting groove 34, thereby realizing the height adjustment of the blanking barrel 7, so as to be suitable for LED lamp beads 01 of different thicknesses.

[0052] like Figures 1 to 3As shown, the top surface of the base 1 is provided with two symmetrical paving grooves 37 located below the unloading barrel 7. The bottoms of the two lamp bead storage plates 8 are respectively fixedly connected with pin limiting plates 38 located inside the corresponding paving grooves 37. When the unloading barrel 7 moves up and down, it can drive the two pin limiting plates 38 to move up and down in the paving grooves 37. When the two lamp bead storage plates 8 move forward and backward, they can drive the pin limiting plates 38 to move forward and backward in the paving grooves 37. The pin limiting plates 38 are flush with the inner side of the pin slide groove 9. Each pin limiting plate Elastic cloth 39 is connected between the front and rear sides of the plate 38 and the front and rear sides of the clearance groove 37. When the LED lamp bead 01 reaches the top surface of the base 1, its metal pin 02 is separated from the pin slide groove 9. At this time, the front and rear ends of the metal pin 02 are in contact with the sides of the two pin limiting plates 38 without moving or deflecting in the front and rear directions. When the spacing between the two lamp bead storage plates 8 is adjusted, the two pin limiting plates 38 drive the elastic cloth 39 connected to them to stretch, thereby protecting the clearance groove 37 and preventing the LED lamp bead from falling into the clearance groove 37.

[0053] like Figure 1 、 Figure 2 、 Figures 4 to 6 As shown, the conveying riser 13 is penetrated by a conveying lifting groove 40 in front and back, a conveying slider 41 is installed in the conveying lifting groove 40 for sliding up and down, the conveying adjustment plate 14 is fixedly connected to the front side of the conveying slider 41, and a conveying screw 42 is rotatably installed in the conveying lifting groove 40, which penetrates the conveying slider 41 and is threadedly connected thereto;

[0054] The tops of the blanking screw 36 and the conveying screw 42 are coaxially fixedly connected to an adjusting wheel 43, an adjusting belt 44 is connected between the two adjusting wheels 43, and an adjusting knob 45 is coaxially fixedly connected to the top of one of the adjusting wheels 43;

[0055] During use, the unloading screw 36 and the conveying screw 42 can be driven to rotate synchronously by rotating the adjusting knob 45 and the adjusting wheel 43 and the adjusting belt 44. When the conveying screw 42 rotates, it can drive the conveying slider 41 to move up and down in the conveying lifting groove 40, thereby realizing the height adjustment of the conveying buffer plate 15. The unloading barrel 7 and the conveying buffer plate 15 are adjusted synchronously, so that the lowest surface of the conveying buffer belt 19 is always lower than the bottom surface of the unloading barrel 7 (that is, the lowest surface of the conveying buffer belt 19 is always lower than the top surface of the LED lamp bead 01, so that pressure can be applied to the top surface of the LED lamp bead 01, driving it to move to the right).

[0056] like Figure 3As shown, a scale line 54 is provided on the front side of the vertical blanking plate 6, and a pointer 55 is fixedly installed on the bottom of the rear side of the blanking barrel 7. Before use, the height of the blanking barrel 7 can be adjusted according to the scale line 54 and the pointer 55 according to the thickness of the LED lamp bead 01.

[0057] like Figure 1 、 Figures 3 to 5 As shown, the two sides of the lamp bead storage plates 8 that are away from each other are fixedly connected with storage plate screws 46 that respectively pass through the front and rear sides of the discharge barrel 7, and the front and rear sides of the discharge barrel 7 are rotatably mounted with internal screw sleeves 47 that are threadedly connected to the two storage plate screw rods 46. The outer side of each internal screw sleeve 47 is coaxially fixed with a storage plate worm gear 48, and the front and rear sides of the discharge barrel 7 are rotatably mounted with storage plate worms 49 that mesh with the storage plate worm gear 48 on the same side. The left ends of the two storage plate worms 49 are connected to storage plate pulleys 50, and a storage plate driving wheel 51 is rotatably mounted on the left side surface of the discharge barrel 7. A storage plate belt 52 is connected between the storage plate driving wheel 51 and the two storage plate pulleys 50, and the storage plate driving wheel 51 is coaxially fixedly connected with a storage plate adjusting knob 53;

[0058] When in use, by turning the storage plate adjustment knob 53, the two storage plate pulleys 50 can be driven to rotate synchronously through the storage plate driving wheel 51, so that the two storage plate worms 49 rotate synchronously and drive the two storage plate worm wheels 48 and the two inner screw sleeves 47 to rotate synchronously, thereby driving the two storage plate screw rods 46 to move back and forth synchronously, so that the two lamp bead storage plates 8 can be moved closer to or away from each other inside the discharge barrel 7, so that LED lamp beads of different sizes and models can be stacked and stored.

[0059] like Figure 1 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 12 As shown, the left ends of the two electrode sheets 24 located in the same electrode adjustment plate 22 are respectively fixedly connected with a guide arc plate 56. The guide arc plate 56 allows the metal pin 02 of the LED lamp bead 01 to smoothly enter between the two electrode sheets 24. Each electrode sheet 24 is composed of multiple electrode short sheets. An insulating block 57 is fixedly connected between every two electrode short sheets. Every two upper and lower corresponding electrode short sheets are connected to the same electrostatic voltage. Multiple groups of electrode short sheets are connected to electrostatic voltages of different volts from left to right (the connected electrostatic voltage increases from left to right). When the LED lamp bead moves from left to right, different electrostatic voltages can be connected in sequence, thereby reflecting the anti-static ability of the LED lamp bead. If the LED lamp bead can withstand all electrostatic voltages, it is a qualified product, otherwise it is a failed product.

[0060] An electrode adjustment groove 58 is passed through the two electrode chutes 21 and the bottom of the base 1. The bottoms of the two electrode adjustment plates 22 are fixedly connected to motor adjustment blocks 59 located in the electrode adjustment groove 58. The bottom of the base 1 is rotatably installed with an electrode bidirectional screw rod 60 threadedly connected to the two electrode adjustment blocks 59. Both ends of the electrode bidirectional screw rod 60 are provided with threads, and the thread directions of the two ends are opposite. The two electrode adjustment blocks 59 are respectively connected to the threads on the same side. The front end of the electrode bidirectional screw rod 60 is installed with an electrode adjustment knob 61;

[0061] During use, the electrode adjustment knob 61 can be rotated to drive the electrode bidirectional screw rod 60 to rotate, thereby driving the two electrode adjustment blocks 59 to move closer to or away from each other, thereby adjusting the distance between the two electrode adjustment plates 22.

[0062] like Figure 1 、 Figure 2 、 Figure 4 and Figure 7 As shown, the rear ends of the conveying wheel 11 located at the right end of the conveying trough 10 and the conveying buffer wheel 18 located at the right end of the conveying buffer plate 15 are coaxially fixedly connected to the conveying worm gear 62 located on the rear side of the base 1, and a conveying double-headed worm 63 is rotatably installed on the rear side surface of the base 1, which is engaged with the two conveying worm gears 62. The spiral directions of the two ends of the conveying double-headed worm gear 63 are opposite, and when it rotates, it drives the two conveying worm gears 62 to rotate in opposite directions (that is, the conveyor belt 12 rotates clockwise and the conveying buffer belt 19 rotates counterclockwise, so that the two can drive the LED lamp bead 01 to move to the right). The conveying double-headed worm gear 63 is connected to the conveying motor 64 installed on the base 1, and the conveying motor 64 is connected to the power supply and the controller. By starting the conveying motor 64 by the controller, the conveying double-headed worm gear 63 can be driven to rotate, thereby driving the two conveying worm gears 62 to rotate synchronously in opposite directions, thereby realizing automatic conveying of the LED lamp bead 01.

[0063] like Figure 1 、 Figure 2 、 Figure 7 、 Figure 10 and Figure 11As shown, the material distributing device 5 includes a material distributing trough 65 opened on the top of the base 1 and located on the right side of the conveying trough 10. The middle part of the bottom surface of the material distributing trough 65 is ball-hinged with a telescopic rod 66. The telescopic rod 66 can use an electric telescopic rod or a hydraulic rod. The telescopic rod 66 is connected to the power supply and the controller. The telescopic end of the telescopic rod 66 is ball-hinged with a material distributing plate 67 that is flush with the top surface of the base 1 and whose top surface is concave in the middle. When the LED lamp bead 01 moves to the right to the rightmost end of the conveyor belt 12 and the conveyor buffer belt 19, the LED lamp bead can reach the top of the material distributing plate 67 and slide to the middle of the material distributing plate 67. The front of the material distributing trough 65 A card slot 68 is provided at the top of the two rear side surfaces, and a "U"-shaped card plate 69 is slidably installed in each of the card slots 68. A card plate shaft 70 is fixedly installed on the front and rear sides of the dividing plate 67. When one of the card plates 69 slides in the direction of the dividing plate shaft 70 and blocks the dividing plate shaft 70, the telescopic rod 66 is started to extend. At this time, the dividing plate 67 can be turned upward with the dividing plate shaft 70 as the center, so that the LED lamp beads on the top of the dividing plate 67 slide to the corresponding position, and then the telescopic rod 66 is shortened and drives the dividing plate 67 to reset to the dividing slot 65, waiting for the next action signal;

[0064] The top of the base 1 is provided with guide grooves 71 located on the front and rear sides of the material distribution trough 65, and each guide groove 71 is installed with a guide inclined plate 72, one of which is connected to the qualified area and the other is connected to the unqualified area. The two card plates 69 are respectively connected to the card cylinders 73 installed on the sides of the two guide grooves 71, and the card cylinders 73 are connected to the power supply and the controller. The controller is connected to the intelligent detection unit. When the intelligent detection unit detects that the LED lamp beads are qualified, it starts the card cylinder 73 on the same side of the qualified area. For example, If the qualified area is the front side of the base 1, the card cylinder 73 on the front side of the dividing trough 65 is started and drives the card 69 connected thereto to clamp the dividing plate shaft 70 on the front side. At the same time, the controller starts the telescopic rod 66 to extend, thereby driving the dividing plate 67 to flip forward with the dividing plate shaft 70 on the front side as the axis, so that the qualified LED lamp beads slide onto the guide inclined plate 72 on the front side and slide into the qualified area for storage. The above structure realizes automatic classification of LED lamp beads, reduces manual operation, and realizes automatic detection of the anti-static ability of LED lamp beads.
