Description

Technical Field

[0001] The utility model relates to the field of lamp board detection, in particular to an automatic detection mechanism for lamp board aging. Background Art

[0002] After M-LED (MicroLED or MiniLED) direct display screens are manufactured, they typically undergo a 6-12 hour burn-in test to confirm whether there are any defects such as dead lights or color shift after prolonged operation. Conventional burn-in testing involves manually installing the light panel onto a cabinet, keeping it lit for an extended period, and then manually determining if there are any defects. Finally, the light panel is removed from the cabinet after the test is complete, a practice that wastes significant labor. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic detection mechanism for lamp board aging, which can automatically perform aging tests on lamp boards and save manpower and material resources.

[0004] The utility model is achieved in this way:

[0005] A lamp board aging automatic detection mechanism includes: a loading device for loading multiple lamp boards to be tested into a test jig, a conductive spring is provided below the test jig; at least one test track, the test track is provided with electrodes for connecting to the conductive spring to perform an aging test on the lamp boards after the test jig is powered on during transportation; at least one lifting device is provided on one side of the test track for receiving the test jig and changing the transmission direction of the test jig on the test track; and a unloading device for sorting the lamp boards on the test jig into different unloading tracks based on the aging test results.

[0006] By installing multiple light boards on a test fixture and electrically connecting the test fixture to the test track, the test fixture can continuously perform power-on tests on multiple light boards during the transmission process. In addition, automatic loading and unloading can be achieved, and light boards with different yields can be sorted according to the aging test results, saving manpower and material resources.

[0007] Furthermore, the mechanism also includes at least one CCD test module, which can be slidably arranged above the test track to perform image detection on the light board carried by the test fixture passing through.

[0008] By setting up at least one CCD test module, image detection can be performed on multiple light boards passing through, making it easier to sort out light boards with different yields.

[0009] Furthermore, the loading device includes a loading rail, a first robotic arm, a first support frame and a first power system. The first support frame is mounted above the loading rail, and the first robotic arm is slidably connected to the first support frame under the control of the first power system; multiple lamp boards to be tested are transmitted along the loading rail, and the first robotic arm grabs the lamp board and slides along the first support frame, and places the lamp board on the test fixture.

[0010] By setting up the loading track, the first robotic arm and the first support frame, multiple light panels to be tested can be automatically loaded on the test fixture, thereby improving the operation speed.

[0011] Furthermore, there are multiple test tracks, and the multiple test tracks are longitudinally spaced a certain distance apart and stacked.

[0012] By arranging multiple test tracks at predetermined intervals longitudinally and stacking them, more test tracks can be laid in a smaller space, thereby extending the test time and saving laying space.

[0013] Furthermore, the test track is one, and the test track is arranged in a spiral shape.

[0014] Furthermore, the lifting device includes a main body, a slide rail and a receiving plate; the slide rail is vertically arranged on the main body, the receiving plate is connected to the slide rail and can slide up and down relative to the slide rail, and the receiving plate is used to receive the test fixture.

[0016] Furthermore, the unloading track includes a first unloading track and a second unloading track, the unloading device includes a second robotic arm, a second support frame and a second power system, the second support frame is erected above the first unloading track and the second unloading track, and the second robotic arm is slidably connected to the second support frame under the control of the second power system; according to the aging test results, the lamp board with high yield on the test fixture is grabbed to the first unloading track by the second robotic arm; the lamp board with low yield on the test fixture is grabbed to the second unloading track.

[0017] By sorting light panels with different yields into different unloading tracks, the subsequent selection time is shortened and work efficiency is improved.

[0018] Furthermore, the mechanism also includes a test fixture useful area, which is arranged on one side of the loading device and accommodates a variety of test fixtures suitable for light boards of different specifications.

[0019] By setting up a spare area for test fixtures of light boards of different specifications, it is convenient to select and use the appropriate test fixture according to the current light board specifications in a timely manner, thereby improving work efficiency.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0027] Please refer to Figure 1 , is a three-dimensional schematic diagram of a light board aging automatic detection mechanism 100 provided by the present invention, and is also referenced simultaneously Figure 2 , is a top view of a light board aging automatic detection mechanism 100 provided by the present invention. The mechanism includes:

[0028] The loading device 110 is used to load multiple lamp boards 120 to be tested into the test fixture 130, and a conductive spring is provided under the test fixture 130 (not shown in the figure). Furthermore, the loading device 110 includes a loading track 111, a first robotic arm 112, a first support frame 113 and a first power system (not shown in the figure). The first support frame 113 is mounted above the loading track 111, and the first robotic arm 112 is slidably connected to the first support frame 113 under the control of the first power system. During actual operation, multiple lamp boards 120 to be tested are transmitted in sequence along the loading track 111. After the first robotic arm 112 grabs the lamp board 120, it slides along the first support frame 113 and places the lamp boards 120 one by one on the test fixture 130. A test fixture 130 can usually accommodate multiple lamp boards 120 to be tested. Each lamp board 120 to be tested is electrically connected to the test fixture 130, and then further electrically connected to the test track 140 through the conductive spring arranged under the test fixture 130, so as to facilitate aging testing after power is turned on.

[0029] It should be noted that the lamp boards 120 usually have different specifications. In order to match the lamp boards 120 of different specifications, a test fixture useful area 200 is also set near the loading device 110. The test fixture useful area 200 is used to accommodate a variety of test fixtures 130 suitable for lamp boards 120 of different specifications, so as to facilitate the replacement of different test fixtures 130 according to the lamp boards 120 of different specifications.

[0030] At least one test track 140 is provided on each test track 140, and an electrode (not shown in the figure) is provided on the test track 140. The electrode is used to electrically connect to the conductive spring sheet below the test fixture 130. When the test fixture 130 is transmitted on the test track 140, the test track 140 can energize the test fixture 130 to perform an aging test on the multiple light boards 120 carried by the test fixture 130. It is easy to understand that the running time or running speed of the test fixture 130 on the test track 140 can be adjusted according to the required aging test time of the light board 120. Generally, the slower the running speed of the test fixture 130 on the test track 140 or the longer the running time, the longer the aging test time.

[0031] Furthermore, the test track 140 can be one, which can be arranged in a spiral shape to increase the track length; in addition, the test track 140 can also be multiple, such as Figure 1 As shown in , multiple test tracks 140 are arranged at a certain distance in the longitudinal direction and stacked, which can increase the length of the test track 140 and meet the needs of different lamp panel aging tests. Figure 1 As shown in , in order to improve the detection effect of the lamp board 120, the mechanism also includes at least one CCD (Charge coupled Device) test module 150. A CCD test module 150 can be set on each test track 140, or a CCD test module 150 can be selectively set for every two test tracks 140. A fixed bracket is provided across the test track 140, and the CCD test module 150 can be slidably set on the fixed bracket to facilitate image detection of the lamp board 120 carried on the test fixture 130 in the passage, including detecting whether there are defects on the surface of the lamp board 120.

[0032] At least one lifting device 160 is provided on both sides of the test track 140, and is used to receive the test fixture 130 and change the transmission direction of the test fixture 130 in the test track 140. Figure 1 As shown, the lifting device 160 includes a main body 161, a slide rail 162 and a receiving plate 163. The main body 161 includes two support plates arranged vertically in the horizontal and longitudinal directions. The slide rail 162 is vertically arranged on the longitudinally arranged support plate in the main body 161. The receiving plate 163 is connected to the slide rail 162 and can slide up and down relative to the slide rail 162. The receiving plate 163 is used to receive the test fixture 130, that is, the size of the receiving plate 163 is greater than or equal to the size of the test fixture 130.

[0033] like Figure 1As shown, the lifting device 160 is set on both sides of the test track 140. When the test fixture 130 is transferred to the end of the first-layer test track 140 and arrives at the lifting device 160, the receiving plate 163 of the lifting device 160 will receive the test fixture 130 and rise along the slide rail 162 to send the test fixture 130 to the second-layer test track 140 for transfer; similarly, when the test fixture 130 is transferred to the end of the second-layer test track 140 and arrives at the Figure 1 When the lifting device 160 on the right side is turned on, the receiving plate 163 will receive the test fixture 130 and send the test fixture 130 from the second layer to the third layer test track 140, and the above steps are repeated. It should be noted that since the aging test time required for different lamp panels 120 is different, not all test tracks 140 need to be transferred for each aging test. According to the actual aging test requirements, the test fixture 130 can be set to only transfer one or two test tracks 140. After the predetermined test requirements are met, it can be transferred by the test fixture located at the third layer. Figure 1 The receiving plate 163 of the lifting device 160 on the right side removes the test fixture 130 from the test track 140 and enters the subsequent process flow.

[0034] The unloading device 170 sorts the lamp panels 120 on the test fixture 130 into different unloading tracks based on the aging test results. The unloading tracks include a first unloading track 181 and a second unloading track 182. The unloading device 170 includes a second robotic arm 171, a second support frame 172, and a second power system (not shown in the figure). The second support frame 172 is mounted above the first unloading track 181 and the second unloading track 182. The second robotic arm 171 is slidably connected to the second support frame 172 under the control of the second power system. Based on the aging test results, the second robotic arm 171 is used to grab the lamp panels 120 with high yield on the test fixture 130 and place them on the first unloading track 181, and grab the lamp panels 120 with low yield on the test fixture 130 and place them on the second unloading track 182, so as to achieve sorting of lamp panels 120 with different yields and improve work efficiency.

[0035] During actual operation, the staff will place multiple lamp panels 120 to be tested on the loading track 111 one by one. The first robotic arm 112 will grab the lamp panels 120 from the loading track 111 one by one and place them on the test fixture 130. One test fixture 130 can arrange multiple lamp panels 120 to be tested in an array. A lifting device 160 is set next to the loading device 110. After a test fixture 130 is loaded with lamp panels 120, the receiving plate 163 of the lifting device 160 will receive the test fixture 130 and slide down along the slide rail 162 to send the test fixture 130 to the test track 140 on the first layer. The test fixture 130 will then start to be loaded from the loading device 110. Figure 1The test rails 140 are transported from the right side to the left side, and are transported one by one to the test rails 140 on different layers by the lifting devices 160 arranged on both sides of the test rails 140. After a predetermined number of test rails 140 are transported according to the test requirements, the test rails 140 are transported by the lifting devices 160 arranged on both sides of the test rails 140. Figure 1 The right-side lifting device 160 transports the test jig 130 after the aging test to the platform in front of the unloading device 170. Based on the aging test results, the second robotic arm 171 of the unloading device 170 unloads the higher-yield lamp panels 120 onto the first unloading track 181 and the lower-yield lamp panels 120 onto the second unloading track 182, thereby sorting the lamp panels 120. Finally, after all lamp panels 120 on the test jig 130 have been sorted, they are transferred to the test jig spare area 200 for storage until further use.

[0036] In summary, the present invention provides an automatic detection mechanism for lamp board aging, which includes: a loading device for loading multiple lamp boards to be tested into a test jig, with a conductive spring sheet provided below the test jig; at least one test track, on which electrodes are provided for connecting to the conductive spring sheet, so as to perform an aging test on the lamp boards after the test jig is powered on during transportation; at least one lifting device, provided on one side of the test track, for receiving the test jig and changing the transmission direction of the test jig in the test track; and a unloading device for sorting the lamp boards on the test jig into different unloading tracks based on the aging test results.
