Description

Technical Field

[0001] This invention relates to the field of panel inspection technology, and in particular to a panel re-judgment device. Background Technology

[0002] Currently, monitors and televisions are used in businesses, homes, and social activities. In many situations, there are higher requirements for screen resolution and size, and 100-inch televisions have entered homes. This has made the market increasingly demanding on the production process of large-size panels.

[0003] In the past, large-size panels faced numerous technical bottlenecks, resulting in high production scrap rates and poor quality. This was due to immature production processes, which led to the failure to detect or promptly remove defective panels in the early stages. Consequently, defective products were carried over to the next production stage, affecting product quality.

[0004] Therefore, those skilled in the art are dedicated to developing a panel re-judgment device to manually judge panel defects that have been visually inspected, making up for the shortcomings of missed detections in optical inspection, and further improving the quality of panel inspection. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a panel re-judgment device that performs manual judgment on panel defects that have been visually inspected, making up for the shortcomings of missed detections in optical inspection, and further improving the quality of panel inspection.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a panel re-judgment device, comprising a frame, a conveying mechanism, a lifting mechanism, a flipping mechanism, and a re-judgment platform;

[0007] The conveying mechanism is installed inside the frame, the lifting mechanism is installed on the upper side of the frame, the re-judgment platform is located at the end of the frame, and the tilting mechanism is installed on the frame and located between the conveying mechanism and the re-judgment platform;

[0008] The lifting mechanism lifts the panel on the conveying mechanism and moves it along the frame to a suitable position, then places the panel on the re-judgment platform. After the front inspection is completed, the lifting mechanism transfers the panel to the flipping mechanism. The flipping mechanism flips the panel, and then the re-judgment platform moves to the underside of the flipping mechanism to receive the flipped panel.

[0009] The beneficial effects of this invention are as follows: the lifting mechanism transfers the panel conveyed by the conveying mechanism to the re-judgment platform for manual re-judgment. After the front re-judgment is completed, the lifting mechanism transfers the panel to the flipping mechanism, and the re-judgment platform moves to the underside of the flipping mechanism and receives the flipped panel for manual reverse re-judgment. After the re-judgment is completed, the lifting mechanism transfers the panel to the conveying mechanism for conveying to the next process, thereby manually judging the defects of the visually inspected panel, making up for the shortcomings of the optical inspection that may miss defects, and further improving the panel inspection quality.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the conveying mechanism includes a support frame, on which a plurality of roller assemblies for conveying panels are provided, and a panel alignment mechanism and a panel limiting mechanism are also installed on the support frame.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the panel alignment mechanism and the panel limiting mechanism perform lateral and longitudinal alignment of the panel conveyed by the conveying mechanism, which is conducive to the subsequent lifting mechanism grabbing the panel.

[0013] Furthermore, the panel alignment mechanism includes alignment modules installed on both sides of the support frame. A first mounting plate is installed on the moving end of the alignment module. A plurality of transverse alignment members are installed at intervals on the first mounting plate. The transverse alignment members extend out of the upper surface of the roller assembly. The two alignment modules move relative to each other to laterally align the panel.

[0014] At least one set of guide rail assemblies is also installed on the underside of the first mounting plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the relative movement of the two alignment modules aligns the panel conveyed by the conveying mechanism laterally.

[0016] Furthermore, the panel limiting mechanism includes a second mounting plate installed on the support frame, and a lead screw module is installed on the second mounting plate. A lifting cylinder and a longitudinal alignment component are sequentially installed on the moving end of the lead screw module. The lead screw module drives the longitudinal alignment component to move longitudinally to align the panel longitudinally.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the lifting cylinder actuates to make its longitudinal alignment component extend out of the upper surface of the roller module. The longitudinal alignment component aligns the panel longitudinally during the movement of the screw module, which is conducive to the subsequent lifting mechanism grabbing the panel.

[0018] Furthermore, the lifting mechanism includes a horizontal mounting rod, a vertical lead screw assembly is mounted in the middle of the horizontal mounting rod, and a suction cup frame assembly is mounted on the moving end of the vertical lead screw assembly;

[0021] Furthermore, the longitudinal movement component includes a longitudinal lead screw module mounted on the frame. The moving end of the longitudinal lead screw module is connected to the transverse mounting rod. The end of the longitudinal lead screw module is also equipped with a first drive motor and a synchronous shaft connecting the two sets of longitudinal lead screw modules. The rotation of the first drive motor drives the transverse mounting rod to move along the longitudinal lead screw module.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the rotation of the first drive motor drives the longitudinal lead screw module to move longitudinally, thereby driving the transverse mounting rod to move longitudinally and transferring the panel to the designated position.

[0023] Furthermore, the flipping mechanism includes a vertical mounting plate mounted on the frame, a lifting linear module mounted on the vertical mounting plate, a flipping motor provided at the moving end of the lifting linear module, a gear assembly and a flipping shaft sequentially mounted at the output ends of the two flipping motors, and a flipping suction cup assembly mounted on the flipping shaft.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the rotation of the flip motor causes the flip suction cup assembly to rotate, rotating the panel from the front to the back for manual re-judgment of the back side, which is highly efficient and fast.

[0025] Furthermore, the re-judgment platform includes a manual platform, which is mounted on a mobile base, and a horizontal movement component is installed on the lower side of the mobile base;

[0026] The horizontal moving component includes a horizontal moving motor, a first ball screw is installed at the output end of the horizontal moving motor, and a first screw bearing that cooperates with the first ball screw is installed on the moving base. The rotation of the horizontal moving motor drives the moving base to move horizontally.

[0027] At least one set of guide components is also provided on the lower side of the mobile base.

[0028] The beneficial effect of adopting the above-mentioned further solution is that the horizontal moving motor rotates, thereby driving the manual platform and the moving base to move, which is used to receive the panel after it has been flipped, which is conducive to the subsequent manual re-judgment of the reverse side.

[0029] Furthermore, the manual platform is mounted on the bracket, the bracket is mounted on the mobile base, and each side of the manual platform is provided with a light-shielding roller, with a light-shielding module on the outside of the light-shielding roller.

[0030] The beneficial effect of adopting the above-mentioned further solution is that the light-blocking roller and light-blocking module are used to adjust and block the irradiated light, making the panel outline clearer, which is conducive to manual re-judgment and improves work efficiency.

[0031] Furthermore, the mobile base includes a support frame, on which a second drive motor is mounted, and a second ball screw is mounted at the output end of the second drive motor. A slider is also provided on the support frame, and a second screw bearing that cooperates with the second ball screw is mounted on the slider.

Detailed Implementation

[0044] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

Therefore, they should not be construed as limitations on this invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a panel re-judgment device includes a frame 1, a conveying mechanism 2, a lifting mechanism 3, a flipping mechanism 4, and a re-judgment platform 5. The conveying mechanism 2 is installed inside the frame 1, the lifting mechanism 3 is installed on the upper side of the frame 1, the re-judgment platform 5 is located at the end of the frame 1, and the flipping mechanism 4 is installed on the frame 1 and located between the conveying mechanism 2 and the re-judgment platform 5. The lifting mechanism 3 lifts the panel on the conveying mechanism 2 and moves it along the frame 1 to a suitable position, and then places the panel on the re-judgment platform 5. After the front side is inspected, the lifting mechanism 3 transfers the panel to the flipping mechanism 4. After the flipping mechanism 4 flips the panel, the re-judgment platform 5 moves to the underside of the flipping mechanism 4 and receives the flipped panel.

[0049] In this invention, the lifting mechanism 3 transfers the panel conveyed by the conveying mechanism 2 to the re-judgment platform 5 for manual re-judgment. After the front re-judgment is completed, the lifting mechanism 3 transfers the panel to the flipping mechanism 4, and the re-judgment platform 5 moves to the underside of the flipping mechanism 4 and receives the flipped panel for manual re-judgment of the reverse side. After the re-judgment is completed, the lifting mechanism 3 transfers the panel to the conveying mechanism 2 for conveying to the next process, thereby manually judging the defects of the visually inspected panel, making up for the shortcomings of the optical inspection that may have missed the inspection, and further improving the panel inspection quality.

[0050] like Figure 1 , Figure 2As shown, in some embodiments, the conveying mechanism 2 includes a support frame 6. Both the support frame 6 and the frame 1 are connected by multiple square tubes. Multiple roller assemblies 7 for conveying panels are mounted on the support frame 6. Each roller assembly 7 includes a roller shaft with both ends passing through the support frame 6. Bearings and bearing seats are installed between the roller shaft and the support frame 6. Multiple rollers are spaced apart on the roller shaft, and an anti-slip and shock-absorbing layer is provided on the outer layer of each roller. A panel alignment mechanism 8 and a panel limiting mechanism 9 are also mounted on the support frame 6. The alignment mechanism 8 and the panel limiting mechanism 9 are used for lateral and longitudinal alignment of the panel, positioning the panel in a designated area, thereby facilitating the subsequent gripping of the panel by the lifting mechanism 3.

[0051] like Figure 1 , Figure 2 , Figure 3 As shown, specifically, the panel alignment mechanism 8 includes alignment modules 10 mounted on both sides of the support frame 6. The alignment modules 10 are mounted on a mounting plate and can be linear motors. A first mounting plate 11 is mounted on the moving end of the alignment module 10. The alignment module 10 drives the first mounting plate 11 to move laterally. Multiple laterally aligned members 12 are spaced apart on the first mounting plate 11. Each laterally aligned member 12 includes an alignment rod with a rubber head at its end. The laterally aligned member 12 extends beyond the upper surface of the roller assembly 7. Two alignment modules 10 move relative to each other to laterally align the panel. At least one set of guide rail assemblies 13 is also mounted on the lower side of the first mounting plate 11. The guide rail assemblies 13 guide the first mounting plate 11 during movement, reducing swaying.

[0052] In another embodiment, the panel limiting mechanism 9 includes a second mounting plate 14 mounted on the support frame 6. A lead screw module 15 is mounted on the second mounting plate 14. The lead screw module 15 includes a lead screw, a lead screw bearing, a servo motor, etc. A lifting cylinder 16 and a longitudinal alignment member 17 are sequentially mounted on the moving end of the lead screw module 15. The longitudinal alignment member 17 and the transverse alignment member 12 have the same structure. During the conveying process of the conveying mechanism 2, the lifting cylinder 16 retracts so that its longitudinal alignment member 17 is lower than the upper surface of the roller assembly 7, thereby facilitating the passage of the panel. During alignment, the lifting cylinder 16 extends, and the lead screw module 15 drives the longitudinal alignment member 17 to move longitudinally to align the panel longitudinally.

[0053] like Figure 1 , Figure 4 As shown, it should be noted that Figure 1The two lifting mechanisms 3 represent two extreme positions of the lifting mechanism 3 in the frame 1. In this embodiment, only one lifting mechanism 3 is installed on the frame 1. Specifically, the lifting mechanism 3 includes a horizontal mounting rod 18, and a vertical lead screw assembly 19 is installed in the middle of the horizontal mounting rod 18. The vertical lead screw assembly 19 includes a power lead screw, a lead screw bearing, and a servo motor, etc. A suction cup frame assembly 20 is installed at the moving end of the vertical lead screw assembly 19. The suction cup frame assembly 20 includes a suction cup frame, which is rectangular. Multiple suction cups for adsorbing the panel are installed at the bottom of the suction cup frame. The two ends of the horizontal mounting rod 18 are installed on a longitudinal moving assembly. The longitudinal moving assembly drives the horizontal mounting rod 18 to move along the length of the frame 1, thereby moving the panel to a suitable position.

[0054] The longitudinal movement assembly includes a longitudinal lead screw module 21 mounted on the frame 1. Two sets of parallel longitudinal lead screw modules 21 are mounted on the frame 1. The moving end of the longitudinal lead screw module 21 is connected to the transverse mounting rod 18. A first drive motor 22 and a synchronous shaft connecting the two sets of longitudinal lead screw modules 21 are also mounted at the ends of the longitudinal lead screw modules 21, so that the two ends of the transverse mounting rod 18 move synchronously. The first drive motor 22 rotates and drives the transverse mounting rod 18 to move along the longitudinal lead screw module 21.

[0055] like Figure 1 , Figure 5 As shown, in some embodiments, the flipping mechanism 4 includes a vertical mounting plate 46 mounted on the frame 1. The vertical mounting plate 46 is fixedly connected to the side of the frame 1. A lifting linear module 23 is mounted on the vertical mounting plate 46. The lifting linear module 23 can also be a linear motor. A flipping motor 24 is provided at the moving end of the lifting linear module 23. A gear assembly 25 and a flipping shaft 26 are sequentially mounted at the output ends of the two flipping motors 24. The gear assembly 25 converts vertical rotation into horizontal rotation. A flipping suction cup assembly 27 is mounted on the flipping shaft 26. During the flipping process, the lifting linear module 23 moves upward, lifting the flipping motor 24 and other components a certain distance. The suction cup on the flipping suction cup assembly 27 faces upward. After the lifting mechanism 3 places the panel on the suction cup, the flipping motor 24 rotates, causing the flipping suction cup assembly to rotate 180° so that the reverse side of the panel faces upward, which is used to place the panel on the re-judgment platform 5 later.

[0056] like Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, in another embodiment, the re-judgment platform 5 includes a manual platform 28, which is used to place the panel for manual re-judgment. The manual platform 28 is mounted on a movable base 29, and a horizontal moving component is mounted on the lower side of the movable base 29. The horizontal moving component drives the movable base 29 and the manual platform 28 to move horizontally, facilitating their movement to the underside of the flipping mechanism 4 to receive the flipped panel. Specifically, the horizontal moving component includes a horizontal moving motor 30, which can be a servo motor. A first ball screw 31 is mounted on the output end of the horizontal moving motor 30, and a first screw bearing that cooperates with the first ball screw 31 is mounted on the movable base 29. The rotation of the horizontal moving motor 30 drives the movable base 29 to move horizontally. At least one set of guide components 32 is also provided on the lower side of the movable base 29. The guide components 32 include guide rails and sliders to ensure smooth movement of the movable base 29 and reduce vibration.

[0057] The manual platform 28 is mounted on the bracket 33, and the bracket 33 is mounted on the mobile base 29. Each side of the manual platform 28 is equipped with a light-shielding roller 34, and a light-shielding module 35 is provided on the outside of the light-shielding roller 34. The light-shielding roller 34 and the light-shielding module 35 are used to adjust and block the irradiated light, making the outline of the panel clearer, which is conducive to manual re-judgment and improves work efficiency.

[0058] like Figure 1 , Figure 6 and Figure 8 As shown, the movable base 29 includes a support frame 36, which is fixedly connected by square tubing. A second drive motor 37 is mounted on the support frame 36. The second drive motor 37 can be a servo motor or a stepper motor, which facilitates control of the rotation speed and number of rotations. A second ball screw 38 is mounted on the output end of the second drive motor 37. A slider 39 is also provided on the support frame 36. A second screw bearing 40 that cooperates with the second ball screw 38 is mounted on the slider 39. When the second drive motor 37 rotates, it drives the slider 39 to move. A top rod 41 is hinged to the slider 39. The other end of the top rod 41 is hinged to a flipping frame 42. A rotating shaft 43 is also provided on the side of the flipping frame 42. When the second drive motor 37 rotates, it causes the flipping frame 42 to rotate along the rotating shaft 43, so that the manual platform 28 presents different tilt angles, which facilitates the operator to manually review the panel from different angles and improves work efficiency.

[0059] In this embodiment, the flip frame 42 is also equipped with a plurality of guide rails 44 and guide rail sliders 45 that cooperate with the guide rails 44. A sliding plate 47 is installed on the guide rail slider 45, and a bracket 33 is installed on the sliding plate 47. Pushing the bracket 33 allows the manual platform 28 to slide along the guide rails 44, which further facilitates the operator to review the panel.

[0060] Working principle of this invention:

[0061] S1. After the roller assembly 7 transports the panel to the designated position, the lifting cylinder 16 extends, the lead screw module 15 drives the longitudinal alignment component 17 to move longitudinally, the alignment module 10 drives the transverse alignment component 12 to move laterally, and the transverse alignment component 12 and the longitudinal alignment component 17 position the panel in the designated area.

[0062] S2. The vertical screw assembly 19 drives the suction cup frame assembly 20 to move downward to pick up the panel on the roller assembly 7. After the vertical screw assembly 19 moves upward to lift the panel a certain distance, the first drive motor 22 rotates, causing its horizontal mounting rod 18 and vertical screw assembly 19 to move along the frame 1. After moving to the upper side of the re-judgment platform 5, the vertical screw assembly 19 moves downward to place the panel on the re-judgment platform 5.

[0063] When the panel is being re-judged on the re-judgment platform 5, the operator can control the second drive motor 37 to move so that its top rod 41 lifts the flipping frame 42 and rotates it around the rotating shaft 43, thereby making the manual platform 28 and the panel present different tilt angles, which is conducive to the operator manually re-judging the panel from different angles and improving work efficiency. The operator can also push the bracket 33 so that its manual platform 28 can slide along the guide rail 44, which is further conducive to the operator re-judging the panel.

[0064] S3. After the front panel inspection is completed, the vertical lead screw assembly 19 moves downward to adsorb the panel on the manual platform 28 and transfer it to the flipping mechanism 4;

[0065] S4. The flipping motor 24 rotates to make its flipping suction cup assembly 27 rotate 180°. At this time, the reverse side of the panel is facing up. The moving base 29 moves horizontally to the underside of the flipping mechanism 4 under the push of the horizontal moving motor 30. The flipping suction cup assembly 27 places the panel on the manual platform 28 under the action of the lifting linear module 23. After the horizontal moving motor 30 moves the moving base 29 to the appropriate position, the operator performs a reverse re-judgment.

[0066] S5. After the panel is re-judged, the lifting mechanism 3 transfers the panel on the manual platform 28 to the roller assembly 7, and the roller assembly 7 transports the panel to the next process.
