Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and in particular to a quality detection device and system for LED lamp bead patches. Background Art

[0002] LED lamp beads are a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. In actual use, LED lamp beads are usually mounted on circuit boards and powered in series and parallel through etched wires on the circuit boards, so that the LED lamp beads emit light collectively. Under the existing technology, some quality inspections of LED lamp bead circuit board patches are manual, in which the LED lamp bead patches are powered manually and the presence of non-luminous lamp beads is visually checked to achieve quality inspection. This method is inefficient and the light can cause certain harm to the human eye. Some more advanced factories also use robotic arms to complete the above operations for quality inspection, but there are also problems of light leakage and light pollution, and it is difficult to determine the luminous intensity of each lamp bead more accurately. Usually, it can only detect whether the LED lamp bead patch is luminous as a whole, which has great limitations. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The quality inspection device for LED lamp bead patches of the present invention, through the cooperation of structures such as the light shielding tube, the photosensitive sensor and the lifting installation platform, can avoid light leakage and cause light pollution problems in the workshop when inspecting the LED lamp bead patches, while reducing the influence of external light and light from other lamp beads on the photosensitive sensor, and can simultaneously detect the light intensity parameters of each lamp bead, and the quality control is more stringent.

[0016] Through the coordination of the window sealing plates, side window grooves and air supply structure, the LED lamp beads can be cleaned by jetting air through the window sealing plates before testing the LED lamp bead patches, thereby reducing the probability of dust coverage caused by improper storage, which leads to low lamp bead brightness of the LED lamp bead patches measured by the photosensitive sensor. At the same time, the air pressure is independently generated by the structure, and no external air supply is required, which omits the layout of the workshop air pipes and the installation of air source equipment, reduces the cost of factory construction, and improves the cleanliness of the factory.

[0017] By cooperating with the adjustable top cylinder, the voltage-changing spring sheet, the switching edge plate and other structures, the elasticity of the return spring applied to the piston disc can be automatically adjusted according to the lifting and lowering changes of the lifting mounting platform; when the lifting mounting platform moves downward, the elasticity applied by the return spring to the piston disc is automatically reduced, and the influence of the elastic supporting force of the return spring on the upward movement of the piston disc relative to the integrated cylinder is reduced, thereby increasing the upper limit of the air pressure of the gas generated by the air supply structure; and when the lifting mounting platform moves upward, the elasticity applied by the return spring to the piston disc is automatically increased, so that the return spring has sufficient elastic force to drive the piston disc to move downward and reset.

One end of the internal air supply path 306 is connected to the top of the integrated cylinder 301, and the internal air supply path 306 is connected to the outside with a connecting air pipe 307, and the end of the connecting air pipe 307 is connected with a frame air pipe 308.

[0035] A frame rail clamp 310 is fixedly provided on the lower surface of the detection template 4.

A right-angle rack arm 311 is fixedly provided on the frame air pipe 308. An action gear 312 is meshed on the outside of the right-angle rack arm 311.

[0036] The top of the integrated cylinder 301 is connected to an adjusting top cylinder 313, and a spring pressure plate 314 is arranged in the adjusting top cylinder 313. The spring pressure plate 314 is pressed on the top of the reset spring 303. A vent hole 315 is opened in the spring pressure plate 314. The air pressure on the upper and lower sides of the spring pressure plate 314 is balanced by the setting of the vent hole 315. A pressure plate top shaft 316 is fixedly arranged on the upper surface of the spring pressure plate 314. The upper end of the pressure plate top shaft 316 passes through the top of the adjusting top cylinder 313 and extends to the outside of the adjusting top cylinder 313. The pressure plate top shaft 316 is in air-tight contact with the adjusting top cylinder 313. Under the premise of sufficient strength, the diameter of the pressure plate top shaft 316 is ensured to be thin enough to reduce the influence of the air pressure change in the adjusting top cylinder 313 on the movement of the pressure plate top shaft 316.

[0037] A transformer spring 317 is provided at the upper end of the pressure plate top shaft 316, and the transformer spring 317 provides downward elastic pressure to the pressure plate top shaft 316. A T-shaped slide 318 is fixedly provided at the end of the transformer spring 317. A track optical axis 319 is fixedly provided on the lifting mounting platform 3, and the track optical axis 319 is limitedly inserted through the T-shaped slide 318. A pressure holding plate 320 is fixedly provided at the end of the track optical axis 319, and a pressure holding spring 321 is provided between the pressure holding plate 320 and the T-shaped slide 318.

[0038] A matching top tongue 322 is fixedly provided on the T-shaped slide 318 , and a switching edge plate 323 is fixedly provided on the lifting arm 2 . Under the elastic force of the holding spring 321 , the matching top tongue 322 and the switching edge plate 323 are squeezed and matched.

[0039] A mounting screw hole 501 is provided through the top of the sunshade tube 5, and the light sensitive sensor 6 is screwed in the mounting screw hole 501. A rubber contact soft ring 502 is fixedly provided on the lower edge of the sunshade tube 5. A positioning groove 1001 is provided on the upper surface of the positioning mold plate 10. The positioning groove 1001 is used to position the LED lamp bead patch. A power supply contact is provided in the positioning groove 1001. The power supply contact is in contact with the soldering tin point on the back of the LED lamp bead patch, thereby supplying power to the LED lamp bead patch.

[0040] A quality inspection system for LED lamp bead patches, the system comprising a quality inspection device for LED lamp bead patches, a suction cup moving arm and a code scanning and entry module. The suction cup moving arm sucks the LED lamp bead patches and places them in the quality inspection device for the LED lamp bead patches for inspection. After the inspection is completed, the suction cup moving arm moves unqualified products to a waste box and moves qualified products to the code scanning and entry module. The inspection time and the brightness parameters of each LED lamp bead are entered into the traceability code of the LED lamp bead patches through the code scanning and entry module.

[0041] When the quality inspection device for LED lamp bead patches of the present invention is used, Figure 2 As shown in , the LED lamp bead patch is placed in the positioning groove 1001 so that the LED lamp bead faces upward.

[0042] like Figure 6 and Figure 7 As shown in , the action gear 312 rotates, driving the right-angle rack arm 311 to drive the frame air pipe 308 to move, so that the window sealing plate 8 moves to the inner center position of the light shield tube 5, and the beam nozzle 9 coincides with the axis of the light shield tube 5. The lifting arm 2 controls the lifting installation platform 3 to move downward, and the lifting installation platform 3 and the detection template 4 move downward as a whole. The extrusion part 304 first contacts the positioning mold plate 10 by extrusion, as shown in FIG. Fig.10 As shown in the figure, the piston disk 302 is pushed to move upward relative to the integrated cylinder 301, and the air above the piston disk 302 is squeezed into the internal air supply path 306, enters the interior of the frame air pipe 308 through the connecting air pipe 307, and then passes through the branch connecting pipe 309 to be ejected downward from the beam nozzle 9. Since the beam nozzle 9 corresponds to the lamp beads of the LED lamp bead patch up and down, the airflow ejected downward from the beam nozzle 9 acts on the lamp beads of the LED lamp bead patch, and can perform jet cleaning on the LED lamp beads.

[0043] As the lifting installation platform 3 continues to move downward, the rubber contact soft ring 502 contacts the upper surface of the LED lamp bead patch, so that the lamp beads of the LED lamp bead patch are respectively located in the corresponding light shielding tube 5.

[0044] The control action gear 312 is reversed, so that the frame air pipe 308 is reset and moved. At this time, the window sealing plate 8 moves to the side window groove 7 to close the side window groove 7. The power supply contact in the positioning groove 1001 supplies power to the LED lamp bead patch to light up, and the photosensitive sensor 6 detects the light emission and light intensity of each LED lamp bead patch.

[0045] In the above process, if Fig.10 As shown in the figure, when the lifting and lowering mounting platform 3 moves up to its position, the switching edge plate 323 will squeeze and drive the matching top tongue 322, so that the T-shaped slide 318 moves to the left, and at the same time drives the transformer spring piece 317 to move to the left. When the transformer spring piece 317 moves to the left, the pressure plate top shaft 316 presses against the end of the transformer spring piece 317 close to the T-shaped slide 318. At this time, the downward pressure exerted by the transformer spring piece 317 on the pressure plate top shaft 316 increases, causing the spring pressure plate 314 to move downward, further compressing the return spring 303, and thereby increasing the elastic downward pressure exerted by the return spring 303 on the piston disc 302, so that the return spring 303 has sufficient elastic force to drive the piston disc 302 to move downward and reset.

[0046] When the lifting installation platform 3 moves downward, the matching top tongue 322 moves to the bottom of the switching edge plate 323. At this time, the switching edge plate 323 no longer squeezes and limits the matching top tongue 322. Under the elastic force of the holding spring 321, the matching top tongue 322 and the T-shaped slide 318 move to the right, driving the transformer spring piece 317 to move right, so that the pressure plate top shaft 316 presses against the end of the transformer spring piece 317 away from the T-shaped slide 318. At this time, the transformer spring piece 317 applies a downward pressure on the pressure plate top shaft 316. The spring pressure plate 314 moves upward under the elasticity of the return spring 303. At this time, the return spring 303 is released to a certain degree of compression, so that the elastic downward pressure applied by the return spring 303 to the piston plate 302 is reduced, and the elastic supporting force of the return spring 303 on the piston plate 302 when it moves upward relative to the integrated cylinder 301 is reduced, and the elastic supporting force of the return spring 303 weakens the squeezing force when the lifting mounting platform 3 moves downward, thereby increasing the upper limit of the gas pressure generated by the air supply structure.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
