[0002] A tablet computer, also known as a portable computer, is a small, easy-to-carry personal computer that uses a touch screen as the basic input device. The touch screen allows users to perform operations through a stylus or digital pen instead of a traditional keyboard or mouse. Users can input through built-in handwriting recognition, an on-screen soft keyboard, voice recognition, or a real keyboard. When tablet computers are produced, their sealing performance needs to be tested by sealing testing equipment.

[0003] When using the existing airtightness detector, workers are required to manually load the flat panel back cover, which not only has low installation efficiency, but also causes workers to become fatigued due to long-term operation, resulting in the flat panel back cover being installed in an improper position, which affects the detection and causes damage to the flat panel back cover.

[0028] The positioning unit 22 includes a rubber fixing belt 2201, which is fixedly sleeved on the surface of the toothed conveyor belt 2103. The surface of the rubber fixing belt 2201 is fixedly connected with a positioning rod 2202. The number of positioning rods 2202 is several. One end of the positioning rod 2202 is fixedly connected to a limiting frame 2203. One side of the limiting frame 2203 is fixedly connected to a limiting rod 2204. The inner cavity of the limiting rod 2204 is rotatably connected with a guide wheel 2205 through an axle pin. The surface of the guide wheel 2205 contacts the inner wall of the guide frame 2105. The inner cavity of the limiting frame 2203 is fixedly installed with a first electric telescopic rod 2206. The telescopic end of the first electric telescopic rod 2206 is fixedly connected with a pressure block 2207. Both sides of the pressure block 2207 are provided with inclined blocks 22 08, one side of the inclined block 2208 is in contact with the surface of the pressure block 2207, and the other side of the inclined block 2208 is provided with a spring telescopic rod 2209, one end of the spring telescopic rod 2209 is fixedly connected to the surface of the inclined block 2208, and the other end of the spring telescopic rod 2209 is fixedly connected to the inner wall of the limit frame 2203, and the other side of the inclined block 2208 is fixedly connected with an L-shaped clamping plate 2210; by setting a positioning unit 22, when the positioning unit 22 moves to the upper end of the feeding mechanism 3, under the action of the first electric telescopic rod 2206, the feeding of a single flat-panel back shell is realized, and when the positioning unit 22 moves to the upper end of the load-bearing installation mechanism 4, under the action of the first electric telescopic rod 2206, the unloading of a single flat-panel back shell can be realized, thereby improving the detection efficiency.

[0029] Two sliders 2211 are fixedly connected to the surface of the pressure block 2207, and a slide groove 2212 is provided on the surface of the limiting frame 2203 for use with the sliders 2211; by setting the sliders 2211 and the slide grooves 2212 to cooperate with each other, the pressure block 2207 can be limited, thereby improving the stability of its vertical movement.

[0030] The specific implementation of this embodiment is as follows: when in use, the staff uses an external control switch to start the first motor 2101, the output end of the first motor 2101 drives the first gear 2102 to rotate, the first gear 2102 drives the toothed conveyor belt 2103 to transmit when rotating, the toothed conveyor belt 2103 drives the rubber fixing belt 2201 on the surface to transmit when transmitting, the rubber fixing belt 2201 drives the positioning rod 2202 on the surface to move when transmitting, and the positioning rod 2202 drives the limit rod 2202 to move when moving. When the limiting frame 2203 moves, the limiting frame 2203 drives the limiting rod 2204 to move. When the limiting rod 2204 moves, the guide wheel 2205 moves in the inner cavity of the guide frame 2105. The cooperation between the guide frame 2105 and the guide wheel 2205 can improve the stability of the movement of the limiting frame 2203. When one of the limiting frames 2203 moves to the upper end of the storage box 301, the first electric telescopic rod 2206 is started, and the telescopic end of the first electric telescopic rod 2206 drives the pressure block 2207 upward. After the pressure block 2207 moves upward to release the pressure on the inclined block 2208, the two inclined blocks 2208 move towards each other under the action of the spring telescopic rod 2209. When the two inclined blocks 2208 move towards each other, they drive the two L-shaped clamping plates 2210 to move towards each other. The L-shaped clamping plates 2210 can be used to clamp and fix the tablet rear shell, thereby completing the loading of the tablet rear shell. During the process of the limiting frame 2203 loading the tablet rear shell, after the other limiting frame 2203 moves to the upper end of the bearing mounting mechanism 4, The first electric telescopic rod 2206 is started, and the telescopic end of the first electric telescopic rod 2206 drives the pressure block 2207 to move downward. When moving downward, the pressure block 2207 squeezes the two inclined blocks 2208. After being squeezed, the two inclined blocks 2208 move in the opposite direction to squeeze the two spring telescopic rods 2209, and drive the two L-shaped clamps 2210 to move in the opposite direction. When the L-shaped clamps 2210 release the limit on the tablet rear shell, the tablet rear shell falls downward to the top of the bearing installation mechanism 4, and the unloading of the tablet rear shell is completed.

[0031] Example 2: Please refer to Figure 1 and Figure 6 The present invention provides a technical solution: a flat panel back cover airtightness detection jig. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A feeding mechanism 3 is arranged on the top of the limit frame 13. The feeding mechanism 3 is used in conjunction with the conveying and positioning mechanism 2. The feeding mechanism 3 is used to feed the flat panel back cover.

[0032] As a further limitation of the feeding mechanism 3 of the present invention, the feeding mechanism 3 includes a storage box 301 and a hydraulic cylinder 302. The storage box 301 is fixedly installed on the top of the limit frame 13, and the hydraulic cylinder 302 is fixedly installed in the inner cavity of the limit frame 13. The telescopic end of the hydraulic cylinder 302 penetrates into the inner cavity of the storage box 301 and is fixedly connected with a positioning plate 303. The positioning plate 303 is arranged in the inner cavity of the storage box 301. By setting the feeding mechanism 3, when the positioning unit 22 moves to the upper end of the storage box 301, the telescopic end of the hydraulic cylinder 302 pushes upward quantitatively, so that the flat-plate rear shell in the inner cavity of the storage box 301 moves upward, and the uppermost flat-plate rear shell and the L-shaped clamping plate 2210 in the positioning unit 22 are at the same horizontal position, which can realize quantitative feeding of the flat-plate rear shell.

[0033] T-blocks 304 are fixedly connected to both sides of the positioning plate 303, and T-slots 305 are opened on both sides of the storage box 301 for use with the T-blocks 304; by setting the T-blocks 304 and the T-slots 305 in coordination, the positioning plate 303 can be limited, thereby improving the stability of the vertical movement of the positioning plate 303.

[0034] The specific implementation method of this embodiment is as follows: before inspecting the flat-panel rear shell, the staff places the flat-panel rear shell into the inner cavity of the storage box 301. When the conveying unit 21 drives one of the positioning units 22 to move to the upper end of the storage box 301, the hydraulic cylinder 302 is started, and the stroke of the telescopic end of the hydraulic cylinder 302 is set in advance. The telescopic end of the hydraulic cylinder 302 drives the positioning plate 303 to move upward, so that the flat-panel rear shell moves between the two L-shaped clamps 2210, and the loading of a single flat-panel rear shell is completed.

[0035] Example 3: Please refer to Figure 1 , Figure 7 and Figure 8 The present invention provides a technical solution: a flat panel back cover airtightness detection fixture. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A bearing and mounting mechanism 4 is provided on the top of the operating table 1. The bearing and mounting mechanism 4 is used in conjunction with the conveying and positioning mechanism 2.

[0036] As a further limitation of the bearing and mounting mechanism 4 of the present invention, the bearing and mounting mechanism 4 includes two second electric telescopic rods 401, and the two second electric telescopic rods 401 are fixedly installed on the top of the operating table 1. The telescopic ends of the second electric telescopic rods 401 are fixedly connected to a bearing frame 402, and the bearing frame 402 is arranged at the upper end of the airtightness detector body 11. A micro motor 403 is fixedly connected to one side of the bearing frame 402. The output end of the micro motor 403 passes through the bearing frame 402 and is fixedly connected to a bidirectional screw rod 404. One end of the bidirectional screw rod 404 is rotatably connected to the inner wall of the bearing frame 402 through a bearing, and the bidirectional screw rod 404 is rotatably connected to the inner wall of the bearing frame 402 through a bearing. The surface of the screw rod 404 is threadedly connected to two threaded sleeves 405, and the tops of the two threaded sleeves 405 are fixedly connected to a bearing plate 406, and the bottom of the bearing plate 406 is in contact with the top of the bearing frame 402; by setting up the bearing and installation mechanism 4, it is possible to receive the flat plate rear shell transported by the conveying and positioning mechanism 2, and then, driven by the second electric telescopic rod 401, the flat plate rear shell is placed at the upper end of the airtightness detector body 11. When the height of the flat plate rear shell is adjusted to the specified position, the micro motor 403 drives the bidirectional screw rod 404 to rotate, so that the two bearing plates 406 move in opposite directions, thereby completing the blanking and installation of the flat plate rear shell.

[0037] The bottom of the supporting plate 406 is fixedly connected to a limiting block 407, and the top of the supporting frame 402 is provided with a limiting groove 408 used in conjunction with the limiting block 407; by setting the limiting block 407 and the limiting groove 408 in coordination, the supporting plate 406 can be limited, thereby improving its stability in lateral movement.

[0038] The specific implementation of this embodiment is as follows: when the conveying unit 21 drives one of the positioning units 22 to move to the upper end of the carrier plate 406, the two L-shaped clamping plates 2210 in the positioning unit 22 move in the opposite direction, so that the tablet rear shell inside it falls downward onto the top of the carrier plate 406, and then the second electric telescopic rod 401 is started, and the telescopic end of the second electric telescopic rod 401 drives the carrier frame 402 to move downward. When the carrier frame 402 drives the carrier plate 406 and the tablet rear shell to move downward to the specified position, the micro motor 403 is started, and the micro motor 403 is turned on. The output end of 3 drives the bidirectional screw rod 404 to rotate, and the bidirectional screw rod 404 drives the two threaded sleeves 405 to move in the opposite direction when rotating. When the two threaded sleeves 405 move in the opposite direction, they drive the two bearing plates 406 to move in the opposite direction. After the two bearing plates 406 move in the opposite direction to the specified position, the flat plate rear shell on the top falls downward onto the surface of the airtightness detector body 11, and the installation of the flat plate rear shell can be completed. The airtightness detector body 11 is a dual-channel waterproof and airtightness detection device, which can perform sealing detection on the outer frame and inner frame of the flat plate rear shell.

[0039] A method for using a flat panel rear shell airtightness detection fixture comprises the following steps: S1: The first motor 2101 drives the first gear 2102 to rotate, so that the toothed conveyor belt 2103 drives the positioning unit 22 to move, and the positions of the plurality of positioning units 22 can be adjusted; S2: When the positioning unit 22 moves to the upper end of the storage box 301, the hydraulic cylinder 302 is started by using an external control switch, and the telescopic end of the hydraulic cylinder 302 drives the positioning plate 303 to move upward, so that the positioning plate 303 pushes the flat plate rear shell in the inner cavity of the storage box 301 to move upward, and the stroke of the hydraulic cylinder 302 is set in advance. After the upper flat plate rear shell moves to a horizontal position with the L-shaped clamping plate 2210, the hydraulic cylinder 302 stops working, and the loading of a single flat plate rear shell can be realized; S3: When one of the positioning units 22 loads the flat-panel rear shell, the positioning unit 22 at the upper end of the carrying and mounting mechanism 4 unloads the flat-panel rear shell. When the flat-panel rear shell falls to the surface of the carrying and mounting mechanism 4, the conveying unit 21 stops working. At this time, the carrying and mounting mechanism 4 drives the flat-panel rear shell on its surface to move downward. When the flat-panel rear shell moves downward to the specified position, the micro motor 403 starts, so that the two threaded sleeves 405 drive the two carrying plates 406 to move in the opposite direction. When the carrying plates 406 are out of contact with the flat-panel rear shell, the flat-panel rear shell falls to the surface of the airtightness detector body 11, and the flat-panel rear shell can be tested.
