Description

Technical Field

[0001] The present application relates to the technical field of diffuser plate quality detection, and in particular to a CCD defect detection device for use in the production of quantum dot diffuser plates. Background Art

[0002] Quantum dot diffusers are innovative optical display materials that achieve specific optical effects and functions by embedding one or more layers of quantum dots within the diffuser. As a core optical component in display backlight units, the surface cleanliness of the diffuser directly impacts the brightness and color gamut uniformity of the LCD screen. Therefore, defect detection is a crucial step in diffuser plate production.

[0003] In existing technology, diffusers are commonly inspected for defects using CCD scanning. The inspection apparatus primarily consists of a mounting frame with an inspection station, where the CCD camera is mounted. During inspection, the diffuser is placed within the inspection station. The CCD camera receives and converts optical signals into electrical signals. These signals contain light components of varying wavelengths, which carry important information about the material's properties. The CCD camera captures image information across different wavelengths and, in conjunction with optical filters or spectrometers, analyzes the spectral components to identify defects on the diffuser.

[0004] However, when such diffuser plates are inspected for defects, the placement or removal of the diffuser plates from the inspection station relies too much on manual labor, resulting in low overall inspection efficiency. This makes the diffuser plates unsuitable for large-scale defect inspection, and therefore requires further improvement. Summary of the Invention

[0005] In order to improve the detection efficiency of the diffusion plate, the present application provides a CCD defect detection device for the production of quantum dot diffusion plates.

[0006] The CCD defect detection device provided in this application for the production of quantum dot diffuser plates adopts the following technical solutions:

[0007] A CCD defect detection device for the production of quantum dot diffusion plates includes a mounting frame, a detection head, a discharge bin and a conveying mechanism, wherein the mounting frame has a detection station, and the detection head is arranged on the detection station; the discharge bin is arranged on one side of the detection head, and a storage cavity for storing the diffusion plates is provided in the discharge bin, and a discharge port connected to the storage cavity is provided on one side of the discharge bin; the conveying mechanism includes a conveyor belt and a transfer assembly, the conveyor belt is arranged on the mounting frame and located at the bottom of the detection station, and one end of the conveyor belt extends to the bottom of the discharge port of the discharge bin; the transfer assembly is arranged between the discharge bin and the conveyor belt, so as to transfer the diffusion plates in the storage cavity to the conveyor belt one by one.

[0008] By adopting the above-mentioned technical solution, during inspection, the diffusion plates stored in the storage chamber are transferred one by one to the conveyor belt through the transfer component, and multiple diffusion plates are transferred to the inspection station in turn through the conveyor belt, so that the inspection head on the inspection station can perform defect inspection on multiple diffusion plates in turn, reducing the manual participation when the diffusion plates are moved in or out of the inspection station, and improving the inspection efficiency of the diffusion plates.

[0009] Optionally, a connecting shaft is provided at the bottom of the discharge bin, and the transfer assembly includes a swing frame, an adsorption tube and a swing member. The swing frame is rotatably installed on the connecting shaft, the adsorption tube is connected to the side wall of the swing frame, and the outer peripheral wall of the adsorption tube is provided with a suction nozzle for adsorbing the diffusion plate; there is a first point position and a second point position between the discharge bin and the conveyor belt, when the swing frame swings to the first point position, the suction nozzle is transferred to the discharge port of the discharge bin; when the swing frame swings to the second point position, the suction nozzle drives the diffusion plate to be transferred to the conveyor belt; the swing member is used to drive the swing frame to swing back and forth between the first point position and the second point position.

[0010] By adopting the above technical solution, the swinging member drives the swing frame to swing from the second point to the first point. At this time, the swing frame transfers the suction nozzle to the discharge port of the discharge bin, thereby sucking the diffuser plate at the discharge port. The swing frame is then driven to swing back from the first point to the second point to transfer the sucked diffuser plate to the conveyor belt. This reciprocating process realizes the gradual removal of the diffuser plates in the discharge bin, improving the operational convenience of the entire structure.

[0011] Optionally, the swing frame is connected to a rotating sleeve, which is rotatably installed on the outer peripheral wall of the connecting shaft; the swing member includes a rotating shaft, a rotating cam and a swing bar, the rotating shaft is rotatably set at the bottom of the discharge bin, the rotating cam is coaxially set on the rotating shaft, and an eccentric column is provided on the surface of the rotating cam; one end of the swing bar is connected to the rotating sleeve, and the side wall of the swing bar is provided with a swing groove for the eccentric column to be embedded.

[0012] By adopting the above-mentioned technical solution, the rotating shaft is driven to rotate, and the eccentric column is driven to "revolve" around the central axis of the rotating shaft. The eccentric column pushes the swing bar through the inner wall of the swing groove to realize the reciprocating swing of the swing bar, that is, the reciprocating swing of the swing frame, so that the swing frame can swing back and forth between the first point position and the second point position to transfer the diffusion plates in the discharge bin to the conveyor belt one by one.

[0013] Optionally, the diffusion plate in the storage chamber normally slides toward the discharge port, and the number of diffusion plates accommodated at the discharge port is one; a blocking arm is rotatably provided at the discharge port of the discharge bin, and under normal circumstances, the blocking arm blocks the discharge port; the discharge bin is provided with a first driving member, and when the swing frame swings to the first point position, the first driving member forces the blocking arm to flip to open the discharge port.

[0014] By adopting the above technical solution, as the swing frame drives the suction nozzle to the first position, the first driving member forces the blocking arm to flip, thereby opening the discharge port. This allows the swing frame to transfer the diffuser plate at the discharge port to the conveyor belt through the suction nozzle. After the diffuser plate at the discharge port is removed, the diffuser plate in the storage chamber slides down under its own gravity and automatically replenishes to the discharge port. This process is repeated to achieve the transfer of multiple diffuser plates in the storage chamber to the conveyor belt one by one.

[0015] Optionally, a mounting seat is provided at the bottom of the discharge bin, and a pushing bar is provided on the swing frame; the first driving member includes a linkage gear, a linkage rack and a reset spring, the linkage gear is rotatably mounted on the mounting seat, the blocking arm is connected to a rotating rod, and the rotating rod and the linkage gear are circumferentially linked; the linkage rack is slidably mounted on the mounting seat, and the linkage rack and the linkage gear are meshed for transmission; the reset spring is provided between the linkage rack and the mounting seat, and when the swing frame swings to the first point position, the pushing bar pushes the linkage rack and forces the blocking arm to open the discharge port.

[0016] By adopting the above-mentioned technical solution, when the swing frame swings to the first position, it pushes the linkage rack through the push bar, causing the linkage rack and linkage gear to mesh and transmit. The linkage gear and the rotating rod are circumferentially linked, thereby driving the rotating rod to rotate, causing the blocking arm to rotate about the central axis of the rotating rod to avoid the discharge port. After the swing frame uses the suction nozzle to absorb the diffuser plate at the discharge port, it drives the swing frame to swing toward the second position. The linkage rack is reset by the elastic force of the return spring, forcing the blocking arm to reclose the discharge port, improving the operational convenience of the overall structure.

[0017] Optionally, limit bars are slidably installed on both sides of the storage chamber, and the discharge bin is provided with a second driving member. When the swing frame swings to the first point position, the second driving member forces the two limit bars to approach each other to clamp the diffusion plate in the storage chamber.

[0018] By adopting the above technical solution, the second driving member forces the two limit bars to move closer to or away from each other, so as to control the sliding speed of the diffusion plate in the storage chamber, so that the multiple diffusion plates in the storage chamber can be replenished to the discharge port one by one.

[0019] Optionally, the second driving member includes a pushing block and a compression spring, two pushing blocks are provided, and both pushing blocks are slidably installed on the mounting seat, the two pushing blocks are correspondingly provided with two limit bars, and each pushing block is connected to the corresponding limit bar, and when the two pushing blocks move away from each other, the two limit bars approach each other; the compression spring is provided between the two pushing blocks, and a pushing channel for the pushing bar to pass through is formed between the two pushing blocks, and when the swing frame swings to the first point position, the pushing bar penetrates into the pushing channel and forces the two pushing blocks to move away from each other.

[0020] By adopting the above-mentioned technical solution, when the swing frame swings to the first position, it drives the push bar to penetrate the push channel, forcing the two push blocks to move away from each other, thereby allowing the two limit bars to move closer together, thereby limiting the position of the diffuser plate in the storage chamber and preventing the diffuser plate from sliding. When the swing frame moves the diffuser plate at the discharge port to the second position, the blocking arm recloses the discharge port, and the two push blocks move closer together again under the action of the compression spring, forcing the two limit bars to move away from each other, allowing the diffuser plate in the storage chamber to be automatically replenished to the discharge port, greatly improving the operational convenience of the overall structure.

[0021] Optionally, each of the pushing blocks has a guide surface for the pushing bar to push.

[0022] By adopting the above technical solution and setting the guide surface, when the swing frame swings toward the first point, the push bar can push the two push blocks and force the two push blocks to move away from each other, and cooperate with the compression spring to realize the reciprocating sliding of the push blocks.

[0023] Optionally, the linkage rack is located at the rear end of the pushing channel, and when the swing frame swings to the first point position, the pushing bar penetrates into the pushing channel to push the linkage rack.

[0024] By adopting the above-mentioned technical solution and arranging the linkage rack at the rear end of the push channel, the following effect is achieved: when the swing frame swings to the first position, the push bar first forces the limit bar to limit the diffuser plate in the storage chamber, and then pushes the linkage rack, forcing the blocking arm to rotate to open the discharge port. After the suction nozzle of the swing frame absorbs the diffuser plate at the discharge port, it drives the swing frame to swing from the first position to the second position. At this time, the push bar first disengages from the linkage rack, that is, the blocking arm first resets to close the discharge port, and then the two limit bars reset to release the diffuser plate in the storage chamber, allowing the diffuser plate to be automatically replenished to the discharge port, greatly improving the discharge stability of the overall structure and achieving the effect of discharging materials one by one.

[0025] Optionally, the swing frame is connected to an adsorption seat, which has an adsorption chamber inside. The adsorption seat is connected to an exhaust pipe, and the outlet end of the exhaust pipe and the inlet end of the adsorption pipe are both connected to the adsorption chamber; the adsorption seat is provided with an opening and closing part, and when the swing frame swings to the second point position, the opening and closing part closes the adsorption chamber, and when the swing frame swings out of the second point position, the opening and closing part opens the adsorption chamber.

[0026] By adopting the above technical solution, the suction chamber opens as the swing frame swings from the second position to the first position, allowing the suction nozzle to absorb the diffuser plate at the discharge port. After the suction nozzle absorbs the diffuser plate, it drives the swing frame to swing from the first position to the second position. At this time, the opening and closing member closes the suction chamber, thereby transferring the diffuser plate to the conveyor belt, improving the overall structure's ease of operation.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through the arrangement of the conveyor belt and transfer assembly, during inspection, the transfer assembly transfers the diffuser plates stored in the storage chamber one by one to the conveyor belt, and the conveyor belt sequentially transfers multiple diffuser plates to the inspection station, so that the inspection head at the inspection station can perform defect inspection on multiple diffuser plates in sequence, reducing the manual intervention when moving the diffuser plates into or out of the inspection station, and improving the inspection efficiency of the diffuser plates;

[0029] 2. By setting the swing member, the swing frame is driven to swing from the second point to the first point. At this time, the swing frame transfers the suction nozzle to the discharge port of the discharge bin, thereby adsorbing the diffuser plate at the discharge port. Then, the swing frame is driven to swing from the first point again to the second point to transfer the adsorbed diffuser plate to the conveyor belt. This reciprocating process realizes the gradual removal of the diffuser plates in the discharge bin, improving the operational convenience of the entire structure.

[0030] 3. By placing the linkage rack at the rear end of the push channel, when the swing frame swings to the first position, the push bar first forces the limit bar to limit the diffuser plate in the storage chamber, and then pushes the linkage rack, forcing the blocking arm to rotate to open the discharge port. After the swing frame's suction nozzle absorbs the diffuser plate at the discharge port, it drives the swing frame to swing from the first position to the second position. At this time, the push bar first disengages from the linkage rack, that is, the blocking arm first resets to close the discharge port, and then the two limit bars reset to release the diffuser plate in the storage chamber, allowing the diffuser plate to be automatically replenished to the discharge port. This greatly improves the discharge stability of the overall structure and achieves a one-by-one discharge effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The side wall of the mounting frame 1 is fixedly mounted with a connecting shaft 12, and the connecting shaft 12 is located at the bottom of the discharge bin 3; the transfer assembly 5 includes a swing frame 51, an adsorption tube 52 and a swing member, the swing frame 51 is fixedly connected to a rotating sleeve 511, the rotating sleeve 511 is rotatably mounted on the outer peripheral wall of the connecting shaft 12, and the swing frame 51 is rotatably mounted on the outer peripheral wall of the connecting shaft 12 through the rotating sleeve 511; the adsorption tube 52 is fixedly connected to the side wall of the swing frame 51, and the adsorption tube 52 can be connected and fixed to the swing frame 51 through a clamp, and the outer peripheral wall of the adsorption tube 52 is mounted with a plurality of suction nozzles 521 for adsorbing the diffusion plate, and the plurality of suction nozzles 521 are arranged at intervals along the axial direction of the adsorption tube 52, and each suction nozzle 521 is connected to the interior of the adsorption tube 52; the adsorption tube 52 is connected to an exhaust pipe 82 (the exhaust pipe 82 is not shown in the figure of this embodiment), the exhaust pipe 82 is a hose, the inlet end of the exhaust pipe 82 is connected to the interior of the adsorption tube 52, and the outlet end of the exhaust pipe 82 is used to connect an external exhaust device (such as an exhaust pump).

[0048] There is a first point position 13 and a second point position 14 between the discharge bin 3 and the conveyor belt 4. When the swing frame 51 swings to the first point position 13, the swing frame 51 drives the suction nozzle 521 to move to the discharge port 32 of the discharge bin 3; when the swing frame 51 swings to the second point position 14, the suction nozzle 521 drives the diffusion plate to move to the conveyor belt 4.

[0049] Reference Figure 4 、 Figure 5The swing member is used to drive the swing frame 51 to swing back and forth between the first point 13 and the second point 14. The swing member includes a rotating shaft 53, a rotating cam 54 and a swing bar 55. The rotating shaft 53 is rotatably mounted on the side wall of the mounting frame 1 and is located at the bottom of the connecting shaft 12. The rotating cam 54 is fixedly mounted on the outer peripheral wall of the rotating shaft 53. The surface of the rotating cam 54 is rotatably connected to the eccentric column 541. The central axis of the eccentric column 541 is arranged parallel to the central axis of the rotating shaft 53, so that when the rotating shaft 53 rotates, the eccentric column 541 can "revolve" around the central axis of the rotating shaft 53.

[0050] One end of the swing bar 55 is fixedly connected to the rotating sleeve 511, and the side wall of the swing bar 55 is provided with a swing groove 551 for the eccentric column 541 to be embedded, and the two ends of the swing groove 551 extend radially along the connecting shaft 12; in this embodiment, the side wall of the mounting frame 1 is fixedly mounted with a drive motor 15, and the output shaft of the drive motor 15 is coaxially connected to the rotating shaft 53; when the rotating shaft 53 rotates, the rotating shaft 53 forces the swing bar 55 to swing back and forth around the central axis of the connecting shaft 12 through the eccentric column 541, and forces the swing frame 51 to swing back and forth between the first point position 13 and the second point position 14.

[0051] Reference Figure 2 、 Figure 3 In this embodiment, the number of diffusion plates accommodated at the discharge port 32 is one, and a blocking arm 6 is provided at the discharge port 32 of the discharge bin 3. There are two blocking arms 6, and each blocking arm 6 is fixedly connected to a rotating rod 64. The rotating rod 64 is rotatably installed on the side wall of the discharge bin 3, and the blocking arm 6 is rotatably installed on the discharge bin 3 through the rotating rod 64. Under normal circumstances (when the swing frame 51 swings to the second point position 14), the blocking arm 6 blocks the discharge port 32; the discharge bin 3 is provided with two groups of first driving members, and the two groups of first driving members are corresponding to the two groups of blocking arms 6. When the swing frame 51 swings to the first point position 13, the first driving member forces the corresponding blocking arm 6 to flip to open the discharge port 32.

[0052] Reference Figure 3 、 Figure 6 、 Figure 7 A mounting base 33 is fixedly installed at the bottom of the discharge bin 3. The first driving member includes a linkage gear 61, a linkage rack 62 and a return spring 63. The linkage gear 61 is rotatably installed on the mounting base 33. The bottom wall of the mounting base 33 is rotatably installed with a reversing gear 331. The reversing gear 331 and the linkage gear 61 are meshed and transmitted. The reversing gear 331 and the rotating rod 64 of the blocking arm 6 are connected in series through a belt, so that the rotating rod 64 of the blocking arm 6 and the linkage gear 61 are circumferentially linked (that is, when the linkage gear 61 rotates, the rotating rod 64 is driven to rotate synchronously).

[0053] The linkage rack 62 is slidably installed on the mounting seat 33, and the linkage rack 62 and the linkage gear 61 are meshed for transmission; the return spring 63 is installed between the linkage rack 62 and the mounting seat 33. Under normal circumstances, the return spring 63 forces the blocking arm 6 to block the discharge port 32. The side wall of the swing frame 51 is fixedly connected with a push bar 512. The push bar 512 is arc-shaped, and the virtual central axis of the push bar 512 is arranged to coincide with the central axis of the connecting shaft 12. When the swing frame 51 swings to the first point 13, the push bar 512 pushes the linkage rack 62 and forces the blocking arm 6 to open the discharge port 32.

[0054] Reference Figure 3 、 Figure 6 、 Figure 8 In this embodiment, the discharge bin 3 has limiting slide grooves 34 on both sides of the storage cavity 31, and a limiting bar 7 is slidably installed in each limiting slide groove 34; the discharge bin 3 is provided with a second driving member. When the swing frame 51 swings to the first point position 13 (that is, when the blocking arm 6 is in the open state), the second driving member forces the two limiting bars 7 to approach each other to clamp the diffusion plate in the storage cavity 31.

[0055] The second driving member includes a pushing block 71 and a compression spring. There are two pushing blocks 71. The two pushing blocks 71 are slidably installed on the bottom wall of the mounting seat 33. The two pushing blocks 71 are corresponding to the two limit bars 7. Each pushing block 71 is connected to the corresponding limit bar 7. Each pushing block 71 is fixedly connected to a connecting bar 72. A connecting frame 73 is connected between the connecting bar 72 of the pushing block 71 and the corresponding limit bar 7. The connecting bar 72 of the pushing block 71 and the corresponding limit bar 7 are connected to each other through the connecting frame 73. It should be noted that in this embodiment, the two pushing blocks 71 and the two limit bars 7 are cross-corresponding. When the two pushing blocks 71 move away from each other, the two limit bars 7 approach each other.

[0056] A compression spring (not shown) is disposed between the two push blocks 71 , with its ends fixedly connected to the two push blocks 71 . A push channel 711 is formed between the two push blocks 71 , through which the push bar 512 passes. When the swing frame 51 swings to the first position 13 , the push bar 512 enters the push channel 711 and forces the two push blocks 71 away from each other (i.e., forces the two limit bars 7 toward each other). Each push block 71 has a guide surface 712 for the push bar 512 to push.

[0057] It should be noted that, in this embodiment, the linkage rack 62 is located at the rear end of the push channel 711. When the swing frame 51 swings to the first position 13, the push bar 512 penetrates the push channel 711 and pushes the linkage rack 62. Specifically, when the swing frame 51 swings to the first position 13, the limit bar 7 first clamps the diffuser plate in the storage chamber 31, and then the blocking arm 6 opens the discharge port 32. After the swing frame 51 removes the diffuser plate from the discharge port 32, the blocking arm 6 first blocks the discharge port 32, and then the limit bar 7 releases the diffuser plate in the storage chamber 31, allowing the diffuser plate in the storage chamber 31 to be automatically replenished to the discharge port 32.

[0058] The implementation principle of Example 1 of the present application is: during inspection, the swing frame 51 is forced to swing toward the first point position 13, so that the suction nozzle 521 of the adsorption tube 52 adsorbs the diffusion plate at the discharge port 32 of the discharge bin 3, and then the swing frame 51 is forced to swing toward the second point position 14 to transfer the diffusion plate to the conveyor belt 4; such reciprocating action is used to transfer the diffusion plates in the discharge bin 3 one by one to the conveyor belt 4, and multiple diffusion plates are transferred to the inspection station 11 in turn through the conveyor belt 4, so that the inspection head 2 on the inspection station 11 can perform defect inspection on multiple diffusion plates in turn, reduce the manual participation of the diffusion plates when moving in or out of the inspection station 11, and improve the inspection efficiency of the diffusion plates.

[0059] When the swing frame 51 swings to the first position 13, the swing frame 51 first forces the limit bars 7 to clamp the diffuser plate in the storage chamber 31 through the push bar 512, and then forces the blocking arm 6 to open the discharge port 32. When the swing frame 51 removes the diffuser plate at the discharge port 32, the blocking arm 6 first blocks the discharge port 32, and then the limit bars 7 release the diffuser plate in the storage chamber 31, allowing the diffuser plate in the storage chamber 31 to be automatically replenished to the discharge port 32. The combination of the limit bars 7 and the blocking arm 6 greatly improves the discharge stability of the entire structure, achieves a one-by-one discharge effect, and improves the overall operation convenience of the structure. Example 2

[0060] The embodiments of the present application disclose a CCD defect detection device for use in the production of quantum dot diffuser plates.

[0061] The difference between the CCD defect detection device for quantum dot diffuser plate production disclosed in the embodiment of the present application and embodiment 1 is that:

[0062] Reference Figure 9 、 Figure 10In this embodiment, the side wall of the swing frame 51 is fixedly connected to the adsorption seat 8, and the adsorption seat 8 has an adsorption chamber 81. The outlet end of the exhaust pipe 82 is connected to the adsorption chamber 81. A connecting pipe 83 is connected between the adsorption tube 52 and the adsorption seat 8. The connecting pipe 83 is a hose. One end of the connecting pipe 83 is connected to the inside of the adsorption tube 52, and the other end is connected to the adsorption chamber 81. The adsorption tube 52 and the adsorption chamber 81 are connected through the connecting pipe 83.

[0063] The adsorption seat 8 is provided with an opening and closing part. When the swing frame 51 swings to the second point position 14, the opening and closing part closes the adsorption chamber 81. When the swing frame 51 swings out of the second point position 14, the opening and closing part opens the adsorption chamber 81. The opening and closing part includes a fixed plate 84, a sliding plate 85 and a limit spring 86. The fixed plate 84 is fixedly installed in the adsorption chamber 81. The fixed plate 84 divides the adsorption chamber 81 into a first partition 811 and a second partition 812. The adsorption tube 52 is connected to the first partition 811, and the exhaust tube 82 is connected to the second partition 812. The sliding plate 85 is slidably installed in the second partition 812. The plate surface of the fixed plate 84 is provided with a plurality of first connecting holes 841, and the plate surface of the sliding plate 85 is provided with a plurality of second connecting holes 851. The plurality of first connecting holes 841 and the second connecting holes 851 are staggered.

[0064] The limit spring 86 is installed between the sliding plate 85 and the inner wall of the adsorption chamber 81. Under normal circumstances, the limit spring 86 forces a gap to exist between the sliding plate 85 and the fixed plate 84 (that is, the first partition 811 and the second partition 812 are connected to each other to open the adsorption chamber 81).

[0065] A sliding rod 87 is fixedly installed on the surface of the sliding plate 85 away from the fixed plate 84, and one end of the sliding rod 87 passes through the outside of the adsorption seat 8; a blocking block 16 is fixedly installed on the side wall of the mounting frame 1. When the swing frame 51 swings to the second point 14, the blocking block 16 forces the sliding block to move into the adsorption chamber 81, and the fixed plate 84 and the movable plate fit together to close the adsorption chamber 81.

[0066] The operating principle of Example 2 of the present application is as follows: While the swing frame 51 is swinging from the second position 14 to the first position 13, the adsorption chamber 81 is open, allowing the suction nozzle 521 to adsorb the diffuser plate at the discharge port 32. After the suction nozzle 521 adsorbs the diffuser plate, the swing frame 51 is driven to swing from the first position 13 to the second position 14. At this time, the adsorption chamber 81 is closed, causing the suction nozzle 521 to lose its adsorption effect on the diffuser plate, thereby transferring the diffuser plate to the conveyor belt 4, thereby improving the operational convenience of the overall structure.

[0067] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
