DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Embodiment 1 like Figure 1-Figure 3As shown, a tablet appearance inspection device includes a feeding mechanism 1 and a back detection mechanism 2 and a first transfer mechanism 3 arranged on the feeding mechanism 1, wherein the first transfer mechanism 3 cooperates with the second transfer mechanism 4 to flip the tablet computer on the feeding mechanism 1 by 180° and place it on the front detection mechanism 5, and the rear end of the second transfer mechanism 4 is also provided with a discharging mechanism 6; the front detection mechanism 5 includes a detection platform 51, a rotating plate 53, a support unit 56, a drive assembly 57 and a camera assembly 58, wherein a fixed plate 52 is fixedly arranged in the middle position; the rotating plate 53 is connected to the fixed plate 52 by at least one group of connecting rod assemblies 54 and a group of lifting rod assemblies 55; the support unit 56 is provided with a plurality of groups and is fixedly arranged at the upper end of the rotating plate 53, and the support unit 56 is used to support the tablet computer; the drive assembly 57 is arranged at the lower end of the detection platform 51, and the drive assembly 57 is used to control the rotation of the rotating plate 53 and control the tilt of the rotating plate 53 through the lifting rod assembly 55.

[0035] Among them, by setting up a front detection mechanism 5 to cooperate with the second transfer mechanism 4, when the tablet computer is on the rotating plate 53 in the detection platform 51, the driving component 57 can drive the rotating plate 53 and the tablet computer to rotate, and cooperate with the camera component 58 to realize the collection of appearance information of the tablet computer at multiple angles. At the same time, the driving component 57 will also synchronously drive the lifting rod component 55 to work during operation, and the lifting rod component 55 will drive the rotating plate 53 to tilt, thereby causing the rotating plate 53 to gradually tilt during the rotation process, so that the camera component 58 can obtain the appearance information of the tablet computer at more different angles, thereby ensuring the accuracy of the tablet computer appearance detection and improving the detection efficiency of the tablet computer.

[0036] In the present invention, the loading mechanism 1 conveys the tablet computer to be inspected to the input end of the inspection mechanism; the back inspection mechanism 2 is arranged above the loading mechanism 1, and is mainly used to inspect the back appearance of the tablet computer passing through the back inspection mechanism 2. The main structure of the back inspection mechanism 2 is a camera, and its specific structure is not repeated; the discharging mechanism 6 is mainly used to output the tablet computer after the appearance inspection. The discharging mechanism 6 in the present invention is provided with a plurality of groups of output assembly lines arranged side by side. After the tablet computer is inspected by the front inspection mechanism 5, the second transfer mechanism 4 can place the above-mentioned different products on different output assembly lines for qualified products, unqualified products of front screen appearance and unqualified products of side appearance, so as to facilitate the subsequent processing of the tablet computer.

[0037] Further, if Figure 3-Figure 12As shown, the connecting rod assembly 54 includes a sleeve 541, a slide rod 542 and a first connecting portion 544. The sleeve 541 is fixedly arranged at the upper end of the fixing plate 52; the slide rod 542 is slidably arranged inside the sleeve 541 and a first ball head 543 is fixedly connected to the upper end; the first ball head 543 is clamped inside the first connecting portion 544 and is slidably connected to the first connecting portion 544; A slide groove 531 is formed at the lower end of the rotating plate 53 at a position corresponding to the first connecting portion 544, and the first connecting portion 544 is slidably disposed inside the slide groove 531; The lifting rod assembly 55 includes a threaded sleeve 551, a threaded rod 552, a second ball head 553 and a second connecting portion 554. The threaded sleeve 551 is fixedly arranged at the upper end of the fixed plate 52; the threaded rod 552 is transmission-connected to the threaded sleeve 551 and the upper end is fixedly connected with the second ball head 553; the upper end of the second ball head 553 is connected with the second connecting portion 554, and the second connecting portion 554 is slidably arranged inside the sliding groove 531.

[0038] Among them, by providing multiple groups of connecting rod assemblies 54 and a group of lifting rod assemblies 55, stable support for the rotating plate 53 can be achieved.

[0039] In this embodiment, the connecting rod assembly 54 is arranged in three groups, and the three groups of connecting rod assemblies 54 and one group of lifting rod assemblies 55 are arranged at equal intervals, and the first connecting part 544 and the second connecting part 554 are slidably arranged at the lower end of the rotating plate 53, and the connection method between the first ball head 543 and the first connecting part 544, and the second ball head 553 and the second connecting part 554 is a sliding setting, but the first ball head 543 cannot be separated from the first connecting part 544, and the second ball head 553 cannot be separated from the first connecting part 544.

[0040] It should be noted that when the threaded rod 552 in the lifting rod assembly 55 rises and drives the rotating plate 53 to rise, the threaded rod 552 cannot lift the entire rotating plate 53 synchronously, but lifts one side of the threaded rod 552, so that the rotating plate 53 is tilted. After the rotating plate 53 is tilted, the relative positions of the first ball head 543 and the first connecting portion 544, and the second ball head 553 and the second connecting portion 554 will change to a certain extent. In order to ensure that the first ball head 543 and the first connecting portion 544, and the second ball head 553 and the second connecting portion The connection stability of the first ball head 543 and the second ball head 553 of the sliding rod 542 are made of an elastic part (rubber material can be selected), and the other end of the elastic part connected to the first ball head 543 is fixed to the sliding rod 542, and the other end of the elastic part connected to the second ball head 553 is fixed to the threaded rod 552. Since the elastic part has a certain bending property, the connection stability between the first ball head 543 and the first connecting part 544 and the second ball head 553 and the second connecting part 554 is ensured; In addition, in order to prevent the second ball head 553 from being separated from the second connecting portion 554 , the maximum tilt angle of the rotating plate 53 is set to not exceed 20°.

[0041] Further, if Figure 6-Figure 7 As shown, the rotating plate 53 includes a fixing portion 532 arranged on the outer ring, a transparent portion 533 arranged inside the outer ring, and a supporting portion 534 arranged inside the transparent portion 533 .

[0042] Among them, the setting of the fixed part 532 is convenient for connection with the support unit 56, the connecting rod assembly 54 and the lifting rod assembly 55, the setting of the support part 534 is convenient for cooperation with the rotating rod 573 in the driving assembly 57, and the setting of the transparent part 533 is convenient for the detection of the back camera unit 581 in the camera assembly 58. The transparent part 533 can be made of a transparent acrylic plate or optical glass.

[0043] Further, if Figure 3 As shown, the driving assembly 57 includes a driving unit 571 fixedly arranged at the lower end of the detection platform 51, a bevel gear pair 572 drivingly connected to the driving unit 571, a rotating rod 573 drivingly connected to the bevel gear pair 572, and a belt 574 having one end connected to the rotating rod 573 and the other end connected to the threaded sleeve 551; The upper end of the rotating rod 573 is provided with a plurality of connecting members 575 extending into the interior of the supporting portion 534 , and the other end of the connecting member 575 is fixedly connected with a third ball head 576 . The supporting portion 534 is provided with a spherical groove 5341 at a position corresponding to the third ball head 576 .

[0044] The driving assembly 57 can be provided to synchronously drive the rotating plate 53 and the lifting rod assembly 55 to work, thereby driving the rotating plate 53 to rotate and tilt at the same time.

[0045] In detail, during operation, the driving unit 571 drives the bevel gear pair 572 to work and then drives the rotating rod 573 to rotate. The rotating rod 573 drives the third ball head 576 to rotate through multiple groups of connecting pieces 575 extending into the interior of the support portion 534. Since the third ball head 576 is clamped in the spherical groove 5341 inside the support portion 534, the rotating plate 53 can be driven to rotate through the third ball head 576. At the same time, when the rotating rod 573 rotates, it will also synchronously drive the threaded sleeve 551 to rotate through the belt 574. After the threaded sleeve 551 rotates, it will drive the threaded rod 552 to rotate and make the threaded rod 552 rise. After the threaded rod 552 rises, it will drive the second connecting portion 554 to rise through the second ball head 553, thereby driving one side of the rotating rod 573 to tilt, and finally the rotating plate 53 is rotated and tilted at the same time; The rotating plate 53 tilts while rotating, and cooperates with the camera assembly 58 and the front camera unit 42 to realize the orientation detection of the tablet computer. At the same time, as the tablet computer rotates and tilts, the same position of the tablet computer can be detected at different viewing angles, further ensuring the accuracy of the detection.

[0046] It should be noted that the support portion 534 is transmission-connected to the third ball head 576 via the spherical groove 5341 . Therefore, when the rotating plate 53 rotates, the cooperation between the third ball head 576 and the spherical groove 5341 is not affected, thereby ensuring the stability of the rotating plate 53 during rotation.

[0047] Further, if Fig. 9 As shown, the camera assembly 58 includes at least one group of back camera units 581 fixedly arranged on the upper end of the fixing plate 52 and corresponding to the transparent portion 533 , and at least one group of side camera units 582 fixedly arranged on the upper end of the detection platform 51 .

[0048] In the appearance inspection of tablet computers, problems such as surface defects, edge wear and uneven color may only appear at specific angles. By installing the camera assembly 58 at multiple angles and coordinating the rotation of the tablet computer, the inspection coverage can be improved to ensure that details of all aspects can be captured in a timely manner.

[0049] It should be noted that the back camera unit 581 is mainly used to observe the integrity of the back of the entire device, including the brand label, the back shell surface and the screw position, and the side camera unit 582 captures the corners of the device from different sides to identify potential scratches, dents or irregular boundaries.

[0050] Further, if Figure 13-14As shown, the first transfer mechanism 3 includes a rotating unit 31 disposed on the feeding mechanism 1 , a lifting unit 32 connected to the rotating unit 31 , and a first adsorption unit 33 fixedly connected to the lifting unit 32 and used for adsorbing the tablet computer.

[0051] Among them, after the tablet computer completes the detection work of the back detection mechanism 2 and moves to the first transfer mechanism 3, the first transfer mechanism 3 cooperates with the second transfer mechanism 4 to transfer the tablet computer to the front detection mechanism 5. The specific operation is as follows: first, the lifting unit 32 drives the first adsorption unit 33 to descend and completes the adsorption of the back of the tablet computer, and then the rotation unit 31 works and synchronously drives the lifting unit 32, the first adsorption unit 33 and the tablet computer to rotate 180°. At this time, the screen side of the tablet computer is facing up, and then the three-axis displacement component 41 in the second transfer mechanism 4 drives the second adsorption unit 43 to vacuum adsorb the front of the tablet computer. Then, the first adsorption unit 33 cancels the adsorption of the back of the tablet computer, and the three-axis displacement component 41 can drive the second adsorption unit 43 and the tablet computer to move to the front detection mechanism 5.

[0052] It should be noted that the first adsorption unit 33 achieves a stable grip on the tablet computer through vacuum adsorption or clamping to ensure that it does not slip during transportation, and is equipped with a variety of adsorption modes suitable for tablet computers of different models, which is convenient for quick switching and adjustment.

[0053] Further, if Figure 8 As shown, the second transfer mechanism 4 includes a three-axis displacement component 41 arranged on the detection platform 51 and a second adsorption unit 43 connected to the three-axis displacement component 41 , and at least one group of front camera units 42 are also arranged on the outer side of the second adsorption unit 43 .

[0054] In the tablet computer appearance inspection equipment, the design of the second transfer mechanism 4 is crucial. This mechanism is not only responsible for the transportation of the tablet computer, but also directly affects the efficiency and accuracy of subsequent processing. By combining the three-axis displacement component 41 with the second adsorption unit 43, accurate grasping and flexible positioning of the tablet computer are achieved, thereby providing a reliable foundation for subsequent inspection and processing work.

[0055] The front camera unit 42 is responsible for capturing the surface image of the tablet computer (mainly the screen) in real time during the transportation process, providing high-definition data for subsequent appearance inspection. Through the high-resolution camera, the equipment can capture subtle defects on the surface of the tablet computer. By cooperating with the front camera unit 42 and the back camera unit 581 and the side camera unit 582 in the camera assembly 58, the tablet computer can be inspected in all directions to ensure the accuracy of the appearance inspection.

[0056] It should be noted that the three-axis displacement component 41 allows the device to be accurately translated and adjusted in the three directions of X, Y, and Z, which means that the various angles and positions of the tablet computer can be finely controlled according to specific detection requirements. During the detection process, the equipment can quickly adapt to tablet computers of different models and sizes, ensuring high efficiency and flexibility during the transportation process, and reducing transportation time delays caused by the fixed position of the equipment. Considering that the three-axis displacement component 41 is a prior art, its specific structure will not be repeated.

[0057] Further, if Fig.14 As shown, a pushing mechanism 7 is also arranged at the upper end of the feeding mechanism 1 between the back detection mechanism 2 and the first transfer mechanism 3, and the pushing mechanism 7 includes a pushing unit 71, a pushing plate 72 connected to the pushing unit 71, and a discharging plate 73 arranged on one side of the feeding mechanism 1.

[0058] During operation, if the back detection mechanism 2 detects that there are scratches or other appearance quality problems on the back of the tablet computer, the pushing unit 71 will work and drive the pushing plate 72 to move and then push the tablet computer to the discharge plate 73. The tablet computer will move back along the discharge plate 73 to the unqualified product recovery area to facilitate subsequent operation and processing. Therefore, the pushing mechanism 7 assists in pushing back unqualified products to ensure the normal operation of the production line. When the inspection is completed, qualified products automatically enter the discharge mechanism 6, which will not affect the next round of inspection, improve the efficiency of the production line, and reduce the manpower requirements of subsequent processing links.

[0059] Embodiment 2 The components that are the same or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: like Fig.15 As shown, the present invention also provides a method for detecting the appearance of a tablet computer, comprising the following steps: S1: Back detection, the feeding mechanism 1 conveys the tablet computer to the position of the back detection mechanism 2 for detection; S2: If the test is qualified, a follow-up test is carried out. If the test is unqualified, the unqualified products will be recycled and repaired under the drive of the pushing mechanism 7; S3: material transfer process, the first transfer mechanism 3 cooperates with the second transfer mechanism 4 to turn the tablet computer on the loading mechanism 1 by 180 degrees and place it on the front detection mechanism 5; S4: front detection, the driving component 57 in the front detection mechanism 5 works to drive the tablet computer to rotate and tilt at the same time, and the camera component 58 cooperates with the front camera unit 42 to detect the front, side and back of the tilted tablet computer; S5: Product output: the qualified products are transported to the discharging mechanism 6 under the drive of the second transfer mechanism 4 and the product discharging is completed.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
