Description

Technical Field

[0001] The present invention belongs to the technical field of display panel detection, and in particular relates to a gamma integrated detection device and method for a display screen. Background Art

[0002] Display panels, such as LCD panels, Micro-OLED (Micro Organic Light-Emitting Diode), Micro LED (Micro Light-Emitting Diode), Before shipment, panels, such as those made of silicon diodes (CMOS), require point-to-point inspection to ensure conformity. Conventional panel inspection requires loading the panel, which is then retrieved by a retrieving mechanism and carried to a crimping mechanism (panel point-to-point inspection equipment) for panel inspection. The crimping mechanism electrically connects the test points on the panel to be inspected. After crimping, a transport mechanism transports the crimped panel to the inspection mechanism for inspection. The display image is analyzed to determine if there are any defects. After inspection, the panel is unloaded again by the transport mechanism. Conventional workstations are typically arranged side by side, forming an assembly line. Loading and unloading, and handling with jigs (traces) are typically handled by two separate handling robots, which consumes considerable space and requires a large number of components. Furthermore, conventional equipment typically only has one panel inspection system. Due to the long panel inspection time, other workstations experience extended waiting times, resulting in a longer overall inspection time.

[0003] Therefore, it is necessary to develop a detection device that can integrate the tray storage area, automatic crimping mechanism and detection mechanism, and effectively improve the space occupancy rate, reduce the use of components, and shorten the detection time through the layout design of each workstation. This is an urgent problem to be solved. Summary of the Invention

[0004] In view of all or part of the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a gamma integrated detection device for a display screen, which realizes integrated detection of the display screen by integrating the tray storage area, automatic crimping mechanism and gamma detection mechanism into the same device; and improves space utilization while integrating by arranging the positions of the tray storage area, automatic crimping mechanism and gamma detection mechanism.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an integrated gamma detection device for display screens, comprising a mounting frame, the mounting frame being fixedly provided with at least a tray storage area, an automatic crimping mechanism, a gamma detection mechanism, and a transport mechanism for transporting products and trays; the tray storage area being located at the front of the mounting frame, the automatic crimping mechanism and the gamma detection mechanism being sequentially disposed on the mounting frame on one side of the tray storage area, and the transport mechanism being disposed between the tray storage area and the automatic crimping mechanism. The transport mechanism feeds the product to be tested from the tray storage area to the automatic crimping mechanism for crimping, and unloads the tested product to the tray storage area. The beneficial effects of this technical solution are that, by integrating the tray storage area, automatic crimping mechanism, gamma detection mechanism and conveying mechanism into the same device, the integration of display screen detection is realized; by arranging the tray storage area, automatic crimping mechanism and gamma detection mechanism in sequence, and arranging the conveying mechanism between the tray storage area and the automatic crimping mechanism, the space utilization rate is improved while making the device more concise; by arranging the tray taking unit and the material taking unit on the conveying mechanism at the same time, the material and tray taking can be achieved by using the same mechanism, thereby reducing the use of components and reducing the equipment cost.

[0006] The automatic crimping mechanism includes two automatic crimping units, which are arranged in parallel on the mounting frame. The gamma detection mechanism includes two gamma detection units, each of which detects the product to be tested on the automatic crimping unit. The beneficial effect of this technical solution is that by providing two automatic crimping units and two gamma detection units, each of the two gamma detection units detects the product to be tested after crimping by the corresponding automatic crimping unit, achieving the effect of simultaneously testing two products to be tested, thereby improving detection efficiency.

[0007] The mounting frame between the two automatic crimping units is also provided with a detection buffer station for placing inspected products. The detection buffer station is equipped with a first product sensor for sensing the inspected products. The beneficial effect of this technical solution is that by providing the detection buffer station in the automatic crimping unit, after the product is inspected, the material picking unit is used to place the products from the two automatic crimping units on the detection buffer station. After the material picking unit has finished re-feeding, the inspected products are discharged. This reduces the waiting time of the automatic crimping mechanism and the Gamma detection mechanism, shortens the time required for loading and unloading, and effectively improves inspection efficiency.

[0008] The mounting frame on one side of the transport mechanism also houses an NG material buffer station for storing products with NG results. This station is equipped with a material presence sensor for detecting NG material. By adding the NG material buffer station, products with NG results can be directly removed from the retrieving unit and placed in the NG material buffer station during material handling, ensuring smooth equipment operation and eliminating the need for external components to handle NG materials, reducing component usage.

[0009] The tray storage area features a loading station, an unloading station, and a buffer station for storing empty trays. The unloading station includes a tray stack mounting base and a mounting platform mounted thereon. The platform is equipped with at least two tray positioning assemblies, positioned diagonally. This technology's beneficial effect lies in its diagonal positioning, which prevents inaccurate positioning and feeding errors caused by the low hardness of the tray's cross-direction edges. Furthermore, the buffer station in the tray storage area allows for the recycling of empty trays.

[0010] The tray positioning assembly includes a positioning cylinder and a positioning fixture, which is fixedly connected to the output end of the positioning cylinder. The positioning fixture is equipped with an upper limit block, a positioning block, and a lower limit block from top to bottom. By fixing the positioning fixture to the output end of the positioning cylinder, the positioning fixture can be driven by the cylinder to move away from and toward the tray, achieving precise positioning. Upper and lower limit blocks are installed on the positioning fixture to limit the tray's vertical freedom, further ensuring the tray's positioning accuracy and maintaining the tray's stability during the material removal process.

[0011] The edge shape of the upper limit block and the positioning block acting on one side of the tray matches the shape of the corner of the tray to be clamped. By setting the shape of the upper limit block and the positioning block edge to match the shape of the corner of the tray, the best holding effect is achieved.

[0012] The mounting platform on one side of the tray positioning assembly is also equipped with a positioning pin for fixing the position of the tray positioning assembly. By setting the positioning pin to fix the initial position of part of the tray positioning assembly, if the tray model changes and the positioning assembly needs to be adjusted, only the position of the positioning assembly on the mounting platform needs to be adjusted, rather than the position of the entire positioning assembly, which improves adjustment efficiency.

[0013] The upper end of the tray stack mounting seat is also provided with a tray separation component and a loading position sensor for sensing whether the tray is loaded in place, and the tray separation component is symmetrically arranged; a tray lifting module is also provided on one side of the tray stack mounting seat; the bottom end of the tray stack mounting seat is provided with a drawer-type push-pull member for stacking trays and a position sensor for sensing whether the drawer-type push-pull member is in place. By arranging the drawer-type push-pull member and the first sensor on the tray stack mounting seat, the trays can be stacked in the loading and unloading mechanism, and the drawer-type push-pull member is used to facilitate the removal and placement of full / or empty trays; by arranging the tray separation component, the loading position sensor and the tray lifting module, the stacked tray groups can be separated so that the conveying mechanism can take out and put away the empty trays.

[0014] The conveying mechanism includes an X-moving axis, a Y-moving axis and a grabbing assembly, the Y-moving axis is slidably arranged on the X-moving axis, and the grabbing assembly is slidably connected to the Y-moving axis; the grabbing assembly includes a tray unit and a product unit; the grabbing assembly also includes a grabbing mounting seat, the grabbing mounting seat is slidably connected to the Y-moving axis, a servo slide is fixedly installed on the grabbing mounting seat, and an adapter is slidably arranged on the servo slide; the tray unit and the material taking unit are fixedly connected to the adapter. By arranging X-moving axis and Y-moving axis on the conveying mechanism, the conveying mechanism can be moved in X-direction and Y-direction, so as to move the products to be tested in different functional areas, and realize the movement of the tray unit between the loading station, unloading station and buffer station, so as to realize the recycling of tray while conveying the tray; by arranging the material taking unit and the tray taking unit on the grabbing group at the same time, the integration of the material taking unit and the tray taking unit is realized; at the same time, since the adapter is arranged on the servo slide, the material taking unit and the tray taking unit can be driven to perform lifting movement to facilitate the material taking and tray taking.

[0015] The adapter is a trapezoidal adapter, and the material removal unit is fixedly connected to the lower end of the trapezoidal adapter. A mounting block is also fixedly provided on one side of the trapezoidal adapter, and the tray removal unit is fixedly connected to the trapezoidal adapter via the mounting block. A switching cylinder is also fixedly mounted on the mounting block, and the tray removal unit is fixedly connected to the switching cylinder. The switching cylinder contracts to drive the tray removal unit to move up and down. By fixing the tray removal unit to the mounting block using the switching cylinder, the switching cylinder contracts to drive the tray removal unit to move up and down, realizing the switching between the material removal unit and the tray removal unit, thereby achieving the purpose of using the same handling mechanism to remove materials and remove trays.

[0016] The tray retrieval unit includes a tray suction cup mounting base, which is equipped with several tray suction cups. The tray suction cup mounting base is a hollow square structure that fits around the perimeter of the retrieval unit. This hollow square structure allows the tray suction cup mounting base to fit around the perimeter of the retrieval unit, improving space utilization while also reducing material usage and lowering costs.

[0017] The picking unit includes an R rotating shaft, a code reader, and a product suction cup group. The product suction cup group is fixedly installed at the lower end of the R rotating shaft, and the R rotating shaft can drive the product suction cup group to rotate; the code reader is fixedly installed at the lower end of the trapezoidal workpiece. By setting the R rotating shaft in the picking unit and fixing the product suction cup group at the lower end of the R rotating shaft, the suction cup group is rotated under the drive of the R rotating shaft. After one side of the product to be tested is inspected, the picking unit is used to rotate the product to be tested and inspect the other side, thereby improving the inspection efficiency. By setting a code reader on one side of the product suction cup, when the picking unit is used to pick up the material, the code reader reads the information of the product to be picked up. If the information is correct, the material is fed in. If the information is incorrect, it is placed in the NG material buffer station to ensure the orderly operation of the equipment.

[0018] The product suction cup assembly includes a product suction cup mounting base, which is surrounded by a plurality of product suction cups. A smoothing device for smoothing the product is located in the center of the product suction cup mounting base. This technical solution has the beneficial effect of smoothing the sucked product by providing the smoothing device in the center of the product suction cup mounting base, thereby preventing subsequent testing from being affected by warping of the product during the material removal process and improving the quality of testing.

[0019] The smoothing device is a boss, and a plurality of air blowing holes are provided on the boss, and the plurality of air blowing holes are arranged in parallel. By providing a plurality of air blowing holes, the smoothing purpose can be achieved in the shortest time.

[0020] An integrated gamma detection method for a display screen comprises the following steps: S1, feeding a product to be tested from a tray storage area to a carrier of an automatic crimping unit via a material taking unit; S2, the automatic crimping unit continuously crimps the product to be tested, and after crimping is completed, the product to be tested is moved to a gamma detection unit by moving the carrier to complete the detection; S3, the material taking unit takes and places the product after detection to a detection buffer station; S4, the material taking unit moves to the loading station to take material again and feed the next product to be tested onto the carrier; S5, when the automatic crimping unit crimps the next product to be tested, the material taking unit moves to the detection buffer station and unloads the product placed thereon that has completed detection to the unloading station. The beneficial effect of this technical solution is that the product to be tested is fed into the carrier of the automatic crimping unit through the material picking unit, the product to be tested is continuously crimped by the automatic crimping unit, and after the crimping is completed, the product to be tested is moved to the Gamma detection area by the carrier movement to complete the detection, thereby realizing the integrated detection of the product to be tested; by temporarily placing the product that has completed the detection in the detection buffer station, the product that has completed the detection will be unloaded after the material picking unit completes the re-feeding, thereby reducing the waiting time of the other mechanisms and effectively improving the detection efficiency.

[0021] The step S2 also includes the following steps: S21: the automatic crimping unit continuously crimps one side of the product to be tested, and after the crimping of one side of the product to be tested is completed, the product to be tested is moved to the Gamma detection unit by the carrier to detect the side of the product to be tested after the crimping is completed. After the detection of one side of the product to be tested is completed, the carrier returns to its original position; S22: the product to be tested that has completed the detection on one side is sucked up by the material picking unit and rotated 180° and then placed on the carrier. The automatic crimping unit continuously crimps the other side of the product to be tested, and after the crimping is completed, the product to be tested is moved to the Gamma detection unit by the carrier to detect the other side of the product to be tested. After the product has completed the detection on one side, the material picking unit rotates the product 180° to cooperate with the automatic crimping unit and the Gamma detection unit to complete the bilateral crimping detection of the target product, thereby improving the detection efficiency.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects: by integrating the Tray storage area, the automatic crimping mechanism, the Gamma detection mechanism and the conveying mechanism into the same device, the integrated Gamma detection of the display screen is realized. Specifically, 1: the Tray storage area, the automatic crimping mechanism and the Gamma detection mechanism are arranged in sequence, and the conveying mechanism is arranged between the loading and unloading mechanism and the automatic crimping mechanism, which effectively improves the space utilization rate and effectively reduces the time required for the transfer of the product to be tested between the various mechanisms, thereby improving the detection efficiency; 2: by setting two automatic crimping units and two Gamma detection units, the two automatic crimping units and the two Gamma detection units respectively cooperate with each other, and realize the use of the device disclosed in the present invention to detect two products to be tested at the same time, effectively improving the detection efficiency, reducing the vacancy of the mechanism, and shortening the detection time; 3: by setting a detection cache station in the automatic crimping unit, after the product has completed the detection, the material picking unit is used to place the product on the automatic crimping unit on the detection cache station, and wait for the material picking unit to be loaded. After the re-feeding is completed, the inspected products are unloaded, which reduces the waiting time of the automatic crimping mechanism and the Gamma detection mechanism and shortens the time required for feeding and unloading, effectively improving the detection efficiency; 4: By integrating the material picking unit and the tray picking unit into the same conveying mechanism, and by setting a switching cylinder between the material picking unit and the tray picking unit, the conveying mechanism is switched between the material picking unit and the tray picking unit through the switching cylinder according to the needs of the detection process, so that the same conveying mechanism can be used to pick up materials and take out trays, reducing the use of external components and reducing equipment costs; 5: By setting the material picking unit under the R rotating axis, the material picking unit is used to rotate the product 180° to cooperate with the automatic crimping unit and the Gamma detection unit to realize bilateral crimping and detection of the product to be tested.

DETAILED DESCRIPTION

[0039] The following is a clear and complete description of the technical solutions in the specific embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] In this embodiment, a display screen integrated gamma detection device is provided, combined with Figure 1-3As can be seen, the mounting frame 1 is provided with a tray storage area 2, an automatic crimping mechanism 4, a gamma detection mechanism 5, and a transport mechanism 3. Specifically, the tray storage area 2 is located at the front of the mounting frame 1, and the automatic crimping mechanism 4 and the gamma detection mechanism 5 are also located to one side of the tray storage area 2. The automatic crimping mechanism 4 and the gamma detection mechanism 5 are sequentially arranged on the mounting frame 1, and the transport mechanism 3 is located between the tray storage area 2 and the automatic crimping mechanism 4. The tray storage area 2 is provided with a blanking station 21, a loading station 22, and a buffer station 23 side by side. More specifically, the blanking station 21, the loading station 22, and the buffer station 23 are sequentially arranged in grooves on the mounting frame 1. The automatic crimping mechanism 4 and the Gamma detection mechanism 5 are arranged on the component mounting frame 11, and the component mounting frame 11 is fixedly connected to the mounting frame 1. Specifically, the automatic crimping mechanism 4 includes a left-side automatic crimping unit 41 and a right-side automatic crimping unit 42. The left-side automatic crimping unit 41 and the right-side automatic crimping unit 42 are distributed on the left and right sides of the front of the component mounting frame 11, and the Gamma detection mechanism 5 is arranged at the rear of the component mounting frame 11.

[0042] The internal structures of the unloading station 21, loading station 22 and buffer station 23 are the same. In this embodiment, the unloading station 21 is taken as an example to explain the specific structure. Figure 3 and Figure 4 It can be seen that the unloading station 21 includes a tray stack mounting seat 215. The tray stack mounting seat 215 is a square mounting profile. A drawer-type push-pull member 216 for stacking trays is provided at the bottom of the tray stack mounting seat 215. A handle 2161 is provided on one side of the drawer-type push-pull member 216 to facilitate pulling the drawer-type push-pull member 216 out of the equipment to take and place the trays, thereby improving production safety. Limit blocks 2162 are also provided around it to limit the position of the tray to prevent the tray from moving on the drawer-type push-pull member 216, causing deviations in subsequent loading and unloading. A position sensor 217 is also provided on the side of the bottom of the tray stack mounting seat 215 away from the handle of the drawer-type push-pull member 216 to sense whether the drawer-type push-pull member 216 is pushed into place.

[0043] Positioning components are provided at the four corners of the mounting platform 210 at the upper end of the tray stack mounting seat 215. In this embodiment, the positioning components adopt a diagonal positioning method to avoid the phenomenon that when a cross positioning method is adopted, the positioning is inaccurate due to the low strength of the edge of the tray in the cross direction, resulting in errors when taking and placing the tray. Among them, a positioning pin 2121 is also added to the mounting platform 210 behind the two positioning components II 212 on the left side of the mounting platform 210, which is used to set the initial position reference of the two positioning components II 212 on the left side on the mounting platform 210. When the model of the tray needs to be changed and the position of the positioning component needs to be adjusted, it is only necessary to adjust the position of the two positioning components I 211 on the right side on the mounting platform 210, thereby improving the adjustment efficiency. Both the positioning component I 211 and the positioning component II 212 can move away from or close to the tray, so as to flexibly adjust the clamping of the tray to achieve precise positioning.

[0044] Except for the positioning pin 2121, the positioning assembly I 211 and the positioning assembly II 212 have the same structure. In this embodiment, the specific structure of the positioning assembly is explained through the description of the positioning assembly I 211. Figure 5-6 It can be seen that the positioning component I 211 includes a positioning cylinder 2110 and a positioning fixture. The positioning fixture is fixedly connected to the output end of the positioning cylinder 2110. The contraction of the positioning cylinder drives the positioning fixture connected to it to move away from or closer to the tray, thereby achieving precise support of the tray. The positioning fixture is provided with an upper limit block 2111, a positioning block 2112 and a lower limit block 2113 from top to bottom, wherein the lower limit block 2113 is shorter than the upper limit block 2111 and the positioning block 2112. The positioning block 2112 is used to fix the horizontal freedom of movement of the tray, and the upper limit block 2111 and the lower limit block 2113 are used to limit the vertical freedom of movement of the tray to avoid insufficient positioning accuracy due to the edge of the tray tilting after positioning. The upper limit block 2111 and the lower limit block 2113 cooperate with the positioning block 2112 to make the positioning of the tray more accurate. Among them, the edge shape of the upper limit block 2111 and the positioning block 2112 acting on one side of the Tray is consistent with the shape of the four corners of the Tray to achieve a more stable support for the Tray, making the Tray more stable during the material removal process. In this embodiment, the shape of the edge of the upper limit block 2111 and the positioning block 2112 is an arc shape, which can be changed with the shape of the edges of the four corners of the Tray in other embodiments.

[0045] Also provided on the mounting platform 210 are a tray separation assembly 214 and a loading position sensor 213 for sensing whether the tray has risen into position. Specifically, in this embodiment, the two loading position sensors 213 are symmetrically arranged in the middle of the upper and lower sides of the mounting platform 210; the tray separation assembly 214 is symmetrically arranged in the middle of the left and right sides of the mounting platform 210. The tray separation assembly 214 includes a separation cylinder 2141 and a separation plate. A tray lifting module 218 is also provided on the right side of the tray stack mounting seat 215. The tray lifting module 218 includes a lifting slide and a lifting slide mounting seat. The tray lifting module 218 is fixed to the mounting frame 1 via the lifting slide mounting seat. When the tray on the unloading station mounting platform 210 has finished taking materials or is full of materials, the tray retrieval unit in the conveying mechanism 3 removes the tray on that layer, and the tray lifting slide is raised and lowered to lift the tray stack, waiting for the conveying mechanism 3 to take or put materials. As the next tray rises, the lift slide stops when the loading position sensor 213 detects it's in place. When the tray removal unit grabs the upper tray, the separation cylinders 2141 on both sides of the tray separation assembly 214 drive the separators connected to them toward the stack of trays, inserting them into the gap between the two trays. The lift slide then descends, separating the upper tray from the lower tray.

[0046] like Figure 7 As can be seen, the transport mechanism 3 includes an X-axis 31, a Y-axis 32, and a gripper assembly 33. The Y-axis 32 slides on the X-axis 31. Both the X-axis 31 and the Y-axis 32 are long, rectangular slides equipped with drag chains I 311 and II 321 for placing wiring, ensuring a neat overall appearance. The Y-axis 32 slides on the X-axis 31 via a slider 322. The gripper assembly 33 slides on one side of the Y-axis 32 via a gripper mounting base 331. A drag chain III 330 is also installed on one side of the gripper mounting base 331 for placing wiring. A servo slide 332 is fixedly mounted on the gripper mounting base 331. An adapter slides on the servo slide 332, which houses a material retrieving unit and a tray retrieval unit. Driven by the servo slide, the adapter can be raised and lowered to facilitate material and tray retrieval. Of course, in other embodiments, the transport mechanism may adopt a four-axis or six-axis manipulator or other transport elements that can achieve the purpose of the present invention, which is not limited here.

[0047] Specifically, in this embodiment, combined with Figure 8 and Figure 9It can be seen that the adapter is a trapezoidal adapter 333, which is a hollow structure. The material-retrieving unit is partially provided at the lower end of the trapezoidal adapter 333. The tray-retrieving unit is installed on one side of the bottom end of the trapezoidal adapter 333 through the mounting block 3331. In the initial state, the lower end face of the material-retrieving unit is lower than the lower end face of the tray-retrieving unit in the vertical direction. In this embodiment, the mounting block 3331 is a pentagonal metal mounting block, on which a switching cylinder 337 is also provided. The tray-retrieving unit is fixedly connected to the output end of the switching cylinder 337. When the tray needs to be retrieved or placed, the switching cylinder 337 contracts to drive the tray-retrieving unit to move up and down, so that the lower end face of the tray-retrieving unit is lower than the lower end face of the material-retrieving unit in the vertical direction, thereby realizing the switching between the material-retrieving tray and the tray-retrieving unit, and achieving the purpose of using the same conveying mechanism 3 for retrieving materials and retrieving trays.

[0048] Specifically, the material picking unit includes: R rotating shaft 335, code reader 338 and product suction cup group, the product suction cup group is fixedly installed on the lower end of R rotating shaft 335 by mounting screw 3351, R rotating shaft 335 can drive the product suction cup group to rotate 360 ​​degrees, and the code reader 338 is fixedly installed on one side of the trapezoidal adapter 333 for reading product 10 information. Figure 10-11 As can be seen, the product suction cup assembly includes a product suction cup mounting base 334, on which are mounted several product suction cups 3341, and a smoothing device 3342 in the middle for smoothing the product 10. In this embodiment, the product suction cup mounting base 334 is a rectangular block-shaped mounting base, with product suction cups 3341 for adsorbing the product 10 arranged around its perimeter. The smoothing device 3342 is a long, rectangular boss with several air holes 33420 arranged in two parallel rows on the boss. Several product suction cup air inlet connectors 33410 and air hole air inlet connectors 33421 are located on the other side of the product suction cup 3341. When the product 10 is sucked, the airflow flowing out through the air holes 33420 smoothes out any warping caused by the relatively soft product 10, thereby improving subsequent inspection results. In other embodiments, the smoothing device may also employ an air nozzle or other component capable of achieving the objectives of the present invention, which is not limited here.

[0049] As shown in Figure 12, product 10 is a jig plate with two rows of Micro LEDs or Micro OLEDs placed symmetrically. In this embodiment, it is a jig plate with two rows of Micro OLEDs 102 stacked and placed. Positioning holes 101 are also provided on one side of the jig plate. A foolproof positioning hole 3343 is also provided on the product suction cup mounting seat 334. The foolproof positioning hole 3343 cooperates with the positioning hole 101 on the product 10 to prevent equipment failure caused by installation errors when replacing different models of product suction cup groups. The tray unit includes a tray suction cup mounting seat 336. The tray suction cup mounting seat 336 is a hollow square mounting seat with several tray suction cups 3361 provided thereon. In this embodiment, a tray suction cup 3361 for sucking the tray is provided at each of the four corners. The tray suction cup mounting seat 336 is integrally mounted on the periphery of the product suction cup group, achieving high space utilization while reducing material usage and reducing costs.

[0050] In this embodiment, an NG material buffer station 7 for temporarily placing unread NG materials is also provided on the mounting frame 1 on the left side of the conveying mechanism 3. A material presence sensor (not shown) is provided on the mounting frame 1 for sensing whether there is material in the NG material buffer station 7. When the material picking unit is picking up materials at the loading station 22, if the code reader 338 identifies incorrect information about the product 10 to be picked up, this information is fed back to the control mechanism, which drives the picking unit to remove the unread NG materials and place them in the NG material buffer station 7. This ensures smooth operation of the entire equipment, avoids the use of external components, and improves inspection efficiency. A loading camera module 6 with a large field of view is also provided on the mounting frame 1 in front of the conveying mechanism 3. The loading camera module 6 with a large field of view is screwed to a mounting profile, which is mounted above the tray storage area 2 and the conveying mechanism 3. This position of the loading camera module 6 above the tray storage area 2 and the conveying mechanism 3 prevents the loading camera module 6 from obstructing the movement of the conveying mechanism 3. The loading camera module 6 with a large field of view is provided with a camera, a lens and a light source from top to bottom. The loading camera module 6 takes real-time photos of the tray storage area 2 and feeds back the signal to the transport mechanism 3 so that the transport mechanism 3 can load and unload materials and take and place the tray in time. When the tray taking unit takes and places the tray, the information is fed back to the tray taking unit through photo positioning to drive the tray taking unit to make position correction.

[0051] An automatic crimping mechanism 4 is provided on the mounting frame 1 behind the conveying mechanism 3, which includes two identical automatic crimping units. The structure of the automatic crimping unit can refer to patent CN20220245716.8. Of course, in other embodiments, the automatic crimping unit can also use other components that can achieve the purpose of the present invention, which is not limited here. The two automatic crimping units are symmetrically arranged on the left and right. A detection cache station 8 for temporarily placing the product 10 that has completed the inspection is also provided on the mounting frame 1 between the two automatic crimping units. The detection cache station 8 is also provided with a sensor for sensing the product 10 (not shown in the figure). By setting the detection cache station 8, when the product 10 completes the inspection, there is no rush to unload the material, and the material can be unloaded after it is re-loaded, thereby shortening the overall inspection time. A material discharge correction module 9 is also provided on the mounting frame 1 in front of the detection buffer station 8. The material discharge correction module 9 is provided with a light source, a lens and a correction camera from top to bottom. When the material picking unit sucks the product 10 to be tested from the loading station 22 and places it on the carrier of the automatic crimping unit, the material discharge correction module 9 takes a photo to locate the position of the carrier and feeds back the information to the material picking unit for position correction to avoid the feeding deviation affecting the subsequent detection effect.

[0052] A Gamma detection mechanism 5 is provided on the mounting frame 1 behind the automatic crimping mechanism 4. The specific structure of the Gamma detection mechanism 5 can be referred to Patent 2022104721422. Of course, in other embodiments, the automatic crimping unit can also adopt other components that can achieve the purpose of the present invention, which is not limited here. It includes two Gamma detection units, and the two Gamma units are connected to the same base through a long strip connector. The two Gamma detection units are correspondingly arranged with the two automatic crimping units, and respectively receive the products to be tested 10 that have been crimped from the front automatic crimping unit. The two automatic crimping units and the two Gamma detection units cooperate with each other to realize the detection of the two products to be tested 10, reduce waiting time, and improve detection efficiency.

[0053] Example 2

[0054] In this embodiment, an integrated Gamma detection method is provided. Specifically, Figure 13 As shown, the loading camera module 6 with a large field of view takes a picture of the loading station 22 and feeds the information back to the conveying mechanism 3. After receiving the information, the conveying mechanism 3 moves to the position to be picked up, and reads the information of the product 10 to be picked up through the code reader 338 on the picking unit on the conveying mechanism 3. If the code reading is NG, the NG material to be picked up is conveyed to the NG material buffer station 7 through the picking unit; if the code reading is OK, the product to be tested 10 is moved to the automatic crimping unit through the picking unit, and the product to be tested 10 is placed on the carrier in the automatic crimping unit after the material discharge correction module 9 takes a picture and completes the position correction; repeat the above steps to feed another product to be tested 10 to the carrier of another automatic crimping unit.

[0055] In this embodiment, after the automatic crimping unit receives the product 10 to be tested, it continuously and automatically crimps one side of the product 10. After the crimping is completed, the product 10 that has completed a row of Micro OLEDs 102 is moved to the Gamma detection unit behind it by moving the carrier to detect the row of Micro OLEDs 102 that have completed crimping; after the detection is completed, the carrier returns to its original position, and at the same time, the conveying mechanism 3 receives the information and moves to the automatic crimping unit, and the product 10 that has completed the inspection of a row of Micro OLEDs 102 is sucked up by the material picking unit, and the R rotating shaft 335 drives the product suction cup group to rotate 180° and then places the product 10 on the automatic crimping unit again; repeat the above crimping and detection steps to complete the detection of the product 10 to be tested.

[0056] The retrieving unit picks up the inspected product 10 and places it on the inspection buffer station 8. It then re-takes material from the loading station 22 and feeds the next product 10 to be tested onto the two automatic crimping units. While the automatic crimping units and the Gamma inspection unit are operating, the retrieving unit moves the inspected product 10 from the inspection buffer station 8 to the unloading station 21 and places it into an empty tray. After all the products 10 on the top layer of the loading station 22 are removed, the transport mechanism 3 receives the information and drives the switching cylinder 337 to move, driving the tray retrieval unit down so that its lower end face is vertically lower than the lower end face of the retrieving unit. The empty tray is then picked up and transported to the buffer station 23 by the tray retrieval unit.

[0057] In this embodiment, by setting up a detection cache station 8, two supporting automatic crimping units and a Gamma detection unit, when the detection of the product 10 is completed, the material picking unit is used to temporarily store the inspected product 10 in the detection cache station 8, and the inspected product 10 is unloaded after the re-feeding is completed, thereby reducing the waiting time of the automatic crimping mechanism 4 and the Gamma detection mechanism 5 during the operation of the equipment. In addition, this method can be used to simultaneously detect two products 10 to be tested, thereby improving the detection efficiency.

[0058] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that, without departing from the principles of the present invention, a number of improvements and modifications may be made to the present invention by those skilled in the art, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
