Description

Technical Field

[0001] This utility model relates to the field of LED chip testing, specifically to a Mini LED product testing device. Background Technology

[0002] Mini LEDs (sub-millimeter light-emitting diodes) refer to LED chips with a die size of approximately 100 micrometers. These LED chips are arrayed and used as backlights for displays, primarily in televisions, computer monitors, medical device displays, and automotive infotainment screens, among other applications.

[0003] Side-mounted wiring technology in Mini LED products connects the circuitry on the front and back of the substrate by fabricating high-precision metal traces on the side of the substrate, thereby achieving electrical connection between the front and back circuitry. Mini LED packaging technology directly affects the display effect, reliability, and lifespan of the product. Side-mounted wiring technology and packaging process work closely together in Mini LED products to jointly determine the display effect and reliability. Existing testing devices generally perform illumination testing on the front and back of the product, but there is no corresponding coverage testing on the four sides of the product. Therefore, it is necessary to improve the existing testing devices to enable all-round testing of the product and improve the testing accuracy.

[0004] Therefore, in order to solve the above problems, a Mini LED product testing device is needed to address these technical issues. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a Mini LED product testing device. By installing a horizontal adjustment mechanism on the base and cooperating with a vertical adjustment mechanism, the position of the testing platform mechanism on the base can be adjusted in both the horizontal and vertical directions. This facilitates the corresponding testing with multiple camera mechanisms on the support frame. Through the setting of the testing platform mechanism, the product can be rotated accordingly during testing to change and control the testing angle, thereby improving the product testing effect.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A Mini LED product testing device includes a base, a support frame fixedly mounted on the base, multiple camera mechanisms disposed on the support frame, a lateral adjustment mechanism fixedly mounted on the base, a longitudinal adjustment mechanism installed in conjunction with the lateral adjustment mechanism, and a testing platform mechanism fixedly mounted on the longitudinal adjustment mechanism; the product is mounted on the testing platform mechanism and tested in conjunction with the multiple camera mechanisms.

[0007] Furthermore, the testing platform mechanism includes a testing stand that is slidably and adjustablely mounted on a longitudinal adjustment mechanism, a rotary drive assembly that is mounted in conjunction with the testing stand, and a testing platform assembly that is mounted in conjunction with the rotary drive assembly; the rotary drive assembly rotates to drive the testing platform assembly to rotate and adjust.

[0008] Furthermore, the rotary drive assembly includes a rotary drive mechanism fixedly installed with the detection stand and a rotating rod installed with the output end of the rotary drive mechanism. The upper end of the rotating rod passes through the upper surface of the detection stand and is fixedly installed with the detection table assembly.

[0009] Furthermore, the testing platform assembly includes a testing platform fixedly installed in conjunction with a rotating rod and a positioning block detachably and fixedly connected to the testing platform. The testing platform has a testing platform slot for adjusting and installing in conjunction with the positioning block, and the positioning block has a positioning block opening for adsorbing the product.

[0010] Furthermore, the lateral adjustment mechanism includes a lateral base fixedly installed on the base, a lateral linear drive assembly disposed on the lateral base, a lateral slide mounted in conjunction with the lateral linear drive assembly, and a lateral guide rail slider assembly mounted on the lateral base in conjunction with the lateral slide. The lateral linear drive assembly drives the lateral slide to reciprocate and adjust along the lateral direction of the base.

[0011] Furthermore, the transverse guide rail slider assembly consists of two sets, and the two sets of transverse guide rail slider assemblies are symmetrically arranged relative to the transverse linear drive assembly, and the longitudinal adjustment mechanism is fixedly installed on the transverse slide.

[0012] Furthermore, the longitudinal adjustment mechanism includes a longitudinal base fixedly installed in conjunction with the transverse adjustment mechanism, a longitudinal linear drive assembly installed on the longitudinal base, and a longitudinal guide rail slider assembly installed on the longitudinal base. The detection stand is installed in conjunction with the longitudinal guide rail slider assembly and the longitudinal linear drive assembly. The reciprocating motion of the longitudinal linear drive assembly drives the detection stand to reciprocate.

[0013] Furthermore, the multiple camera mechanisms have the same overall structure and are all fixedly installed with the support frame. The camera mechanism includes a cantilever fixedly installed with the support frame, a camera assembly, an adjustment plate fixedly installed with the camera assembly, and a position adjustment component disposed between the cantilever and the adjustment plate; the camera assembly can be adjusted in installation position through the position adjustment component.

[0014] Furthermore, the position adjustment component includes a cantilever linear slider assembly that is mounted with the cantilever and an angle adjustment assembly that is mounted with the adjustment plate.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a schematic diagram showing the distribution of the various camera components in this utility model; Figure 3 This is a schematic diagram of the lateral adjustment mechanism in this utility model; Figure 4 This is a schematic diagram of the installation of the testing stand of this utility model; Figure 5 This is a schematic diagram of the camera mechanism in this utility model; Figure 6 This is a schematic diagram of the rotary drive mechanism of this utility model; Figure 7This is a top view of the testing platform of this utility model; as shown in the figure, a Mini LED product testing device includes a base 1, a support frame 7 fixedly installed on the base 1, multiple camera mechanisms set on the support frame 7, a horizontal adjustment mechanism 2 fixedly installed on the base 1, a vertical adjustment mechanism 3 installed in conjunction with the horizontal adjustment mechanism 2, and a testing platform mechanism fixedly installed on the vertical adjustment mechanism 3; the product 5 is installed on the testing platform mechanism and tested in conjunction with the multiple camera mechanisms.

[0024] The Mini LED product testing device of this technical solution, by installing a horizontal adjustment mechanism 2 on the base 1 and cooperating with a vertical adjustment mechanism 3, realizes the horizontal and vertical position adjustment of the testing platform mechanism on the base 1. This facilitates the cooperation with multiple camera mechanisms on the support frame 7 (including the lower right camera 8, upper right camera 9, lower camera 10, left camera 11, and upper camera 12, with multiple cameras cooperating to achieve a comprehensive testing effect on the product). Through the setting of the testing platform mechanism, the product 5 can be rotated accordingly during testing to change and adjust the testing angle, thereby improving the product testing effect.

[0025] In this embodiment, the testing platform mechanism includes a testing stand 4 that is slidably and adjustablely mounted on a longitudinal adjustment mechanism, a rotary drive assembly 13 that is mounted in conjunction with the testing stand 4, and a testing platform assembly 14 that is mounted in conjunction with the rotary drive assembly; the rotary drive assembly 13 rotates to drive the testing platform assembly 14 to rotate and adjust.

[0026] The testing stand 4 serves as the overall support structure for the testing table assembly 14 and the rotary drive assembly 13. The testing stand 4 adopts a frame structure. The lower end of the testing stand 4 is connected and installed with the longitudinal adjustment mechanism 3, so that when the longitudinal adjustment mechanism 3 moves, it drives the testing stand 4 to adjust accordingly, ensuring that the product 5 can better cooperate with the various testing structures on the testing table assembly 14 to perform corresponding position testing, thereby improving the overall testing accuracy of the product.

[0027] In this embodiment, the rotary drive assembly 13 includes a rotary drive mechanism 131 fixedly installed with the detection stand 4 and a rotating rod 132 installed with the output end of the rotary drive mechanism. The upper end of the rotating rod 132 passes through the upper surface of the detection stand 4 and is fixedly installed with the detection table assembly 14.

[0028] The rotary drive assembly 13 consists of two parts: a rotary drive mechanism 131 fixedly installed with the inspection stand 4, and a rotating rod 132 installed with the output end of the rotary drive mechanism 131. The rotary drive mechanism 131 can be fixedly installed on the outer surface of its housing with a connecting plate 133 and the two vertical inner sides of the inspection stand 4, which provides support for the rotary drive mechanism 131. The output end of the rotary drive mechanism 131 is correspondingly installed with the rotating rod 132 as its power output end. The upper end of the rotating rod 132 passes through the upper surface 331 of the inspection stand and is fixedly installed with the inspection table assembly 14. There is a certain distance between the lower surface of the inspection table assembly 14 and the upper surface of the inspection stand 4 so that there is no interference when the inspection table assembly 14 rotates. The rotary drive mechanism 131 can be an existing stepper motor or other rotary drive mechanism. The rotary drive assembly 13 realizes the purpose of rotating inspection of product 5 and improves the product inspection effect.

[0029] In this embodiment, the testing platform assembly 14 includes a testing platform 141 fixedly installed in conjunction with the rotating rod 132 and a positioning block 142 detachably and fixedly connected to the testing platform 141. The testing platform has a testing platform slot 143 that is adjusted and installed in conjunction with the positioning block, and the positioning block 142 has a positioning block opening for adsorption of the product.

[0030] The lower end face of the testing table 141 is fixedly installed with the rotating rod 132. Multiple sets of testing table slots 143 are opened on its upper surface. The positioning blocks 142 are fixedly installed with bolts in the testing table slots 143. Threaded holes can be set at certain intervals in the corresponding testing table slots 143 to facilitate fixing and locking with the positioning blocks 142. The positioning blocks can be selected and adjusted according to the size of the product 5. For example, when the size is small, a single positioning block 142 can be used as a support platform. When the size is medium, four adjacent positioning blocks 142 (combined into a rectangular structure) can be used as a support platform. When the size is the largest, the positioning blocks are selected to fill the entire testing table 141. The positioning blocks 142 have positioning block openings. With the help of a vacuum device, the product can be subjected to corresponding adsorption treatment after it is placed, which improves the stability of the product installation. (The specific installation structure of the product with the positioning block openings and the vacuum device can adopt the existing technology, which will not be described here.)

[0031] In this embodiment, the lateral adjustment mechanism includes a lateral base fixedly installed on the base 1, a lateral linear drive assembly (including a lateral linear drive component 21 and a lateral linear slide component 22, the specific model and structure of which can be adopted from the prior art, or a screw and nut pair structure, etc., which will not be described in detail here), a lateral slide 25 installed in conjunction with the lateral linear drive assembly, and a lateral guide rail slider assembly installed on the lateral base in conjunction with the lateral slide 25. The lateral linear drive assembly drives the lateral slide 25 to slide back and forth in the lateral direction of the base 1 for adjustment.

[0032] A transverse base is mounted on base 1. A transverse guide rail slider assembly and a transverse linear drive assembly are mounted on the transverse base. The lower end of the transverse slide 25 is fitted with a transverse linear slider 22. Simultaneously, the transverse slide 25 is also fitted with the transverse guide rail slider assembly to ensure that it moves along the transverse direction (i.e., transverse is...). Figure 1 The stability of the structure during adjustment (the longitudinal direction, i.e., the width direction of the base).

[0033] In this embodiment, there are two sets of transverse guide rail slider assemblies, and the two sets of transverse guide rail slider assemblies are symmetrically arranged with respect to the transverse linear drive assembly. The longitudinal adjustment mechanism is fixedly installed on the transverse slide block 25.

[0034] The transverse guide rail slider assembly includes a transverse slide rail 23 fixedly mounted on a transverse base and a transverse slider 24 fixedly disposed on the lower surface of a transverse slide block 25. The transverse slider 24 slides in cooperation with the transverse slide rail 23. Two sets of guide rail slider assemblies are provided, and the two sets of transverse guide rail slider assemblies are symmetrically arranged relative to the transverse linear drive assembly, which further improves the stability of the product when sliding and adjusting in the transverse direction.

[0035] In this embodiment, the longitudinal adjustment mechanism includes a longitudinal base 31 fixedly installed in conjunction with the transverse adjustment mechanism 2, a longitudinal linear drive assembly installed on the longitudinal base 31, and a longitudinal guide rail slider assembly installed on the longitudinal base. The detection stand 4 is installed in conjunction with the longitudinal guide rail slider assembly and the longitudinal linear drive assembly. The reciprocating motion of the longitudinal linear drive assembly drives the detection stand 4 to reciprocate.

[0036] The lower end of the inspection stand 4 is provided with a stand guide plate 33. Of course, the two can be integrally molded. The stand guide plate 33 is installed in conjunction with the longitudinal linear drive component and the longitudinal guide rail slider component. The longitudinal linear drive component drives the stand guide plate 33 to slide back and forth in the longitudinal direction for adjustment. The two sets of longitudinal guide rail slider components with the same structure ensure the stability of the structure when it slides in the longitudinal direction. Of course, the longitudinal guide rail slider component adopts the method of longitudinal slide rail 32 and longitudinal slider 34 (installed on the lower surface of the stand guide plate 33). The longitudinal linear drive component can adopt a screw and nut drive structure or the same structure as the transverse linear drive component (existing technology is used here and will not be described in detail). By adjusting in the transverse and longitudinal directions, the product adjustment and inspection can be realized.

[0037] In this embodiment, the multiple camera mechanisms have the same overall structure and are all fixedly installed with the support frame. The camera mechanism includes a cantilever 96 fixedly installed with the support frame, a camera assembly, an adjustment plate 97 fixedly installed with the camera assembly, and a position adjustment component disposed between the cantilever 96 and the adjustment plate 97. The camera assembly can be adjusted in installation position through the position adjustment component.

[0038] (The lower right camera 8, upper right camera 9, lower camera 10, left camera 11, and upper camera 12) have the same overall camera mechanism, except for the cantilever 96 which is installed in conjunction with the support frame 7 and the specific installation position. The cantilever 96 is fixedly installed in conjunction with the support frame 7, and the adjustment plate 97 is fixedly installed in conjunction with the camera. The position adjustment structure is arranged between the cantilever 96 and the adjustment plate 97 to adjust the extension position and rotation angle of the camera, so that the position is more accurate when it is aligned with the product for inspection.

[0039] In this embodiment, the position adjustment component includes a cantilever linear slider assembly 95 that is installed in conjunction with the cantilever 96 and an angle adjustment assembly 94 that is installed in conjunction with the adjustment plate 97. The angle adjustment assembly 94 is connected and installed in conjunction with the cantilever linear slider assembly 95.

[0040] Both the angle adjustment component 94 and the cantilever linear slider component 95 adopt existing angular displacement adjustment modules and linear adjustment modules. The two cooperate with each other and are installed in conjunction with the adjustment plate 97 and the cantilever 96, so that the camera can be adjusted in angle and in position relative to the cantilever 96 (in the direction of cantilever length). Of course, the camera is also equipped with a lighting component, including a light source 93, a front mounting bracket 92 and a rear mounting bracket 91 that are fixedly installed with the light source 93. The front mounting bracket 92 and the rear mounting bracket 91 can be adjusted in position and then locked with screws through the waist-shaped hole on the front mounting bracket 92 to ensure the stable position of the light source 93 and provide stable lighting conditions for detection.

[0041] In this embodiment, a position detection component 6 is also included. The position detection component 6 includes a ranging bracket that is fixedly installed with the base 1, a horizontal ranging head 62 and a vertical ranging head 61 set on the ranging bracket.

[0042] The distance measuring bracket is fixedly installed on the base 1 and positioned at the front end of the product's incoming material direction. The distance measuring bracket is equipped with a horizontal distance measuring head 62 and a vertical distance measuring head 61 to measure the horizontal and vertical distances when the product 5 is received, ensuring that the product is installed in the set position. The inspection stand 4 has a clearance opening 332 to facilitate product movement during inspection without interference with the vertical distance measuring head 61.
