[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 9 As shown, the technical solution adopted by the present invention is as follows: a test device for tablet computer production includes a base 1, and a test table 12 is arranged above the base 1.

The rotating disk 7 is slidably matched with the top surface of the base 1. The rotation of the rotating disk 7 is limited by the rotating shaft. A plurality of vertical lines 9 are arranged at intervals on the outer surface of the rotating disk 7, and the vertical lines 9 are used to facilitate the rotation of the rotating disk 7.

[0027] Four inclined slots 8 are evenly arranged on the rotating disk 7. Inclined means that the symmetry line of the inclined slots 8 does not pass through the center of the rotating disk 7.

[0028] Four limiting grooves 4 are provided on the top surface of the base 1, and one of the symmetry lines of the limiting grooves 4 passes through the center of the positioning groove 29. The four inclined grooves 8 and the four limiting grooves 4 are distributed in a circumferential array about the positioning groove 29. The limiting grooves 4 correspond to the inclined grooves 8 one by one up and down, and the same sliding rod 6 is slidably connected in the corresponding limiting grooves 4 and inclined grooves 8. Four sliding rods 6 are provided, and the cross-sectional shape of the sliding rod 6 is circular.

[0029] The bottom end of each sliding rod 6 is fixedly connected to the limiting block 5, and the limiting block 5 is slidably connected to the bottom end in the limiting groove 4. Through the limitation of the limiting block 5, the sliding rod 6 can only slide along the direction of the limiting groove 4.

[0030] A hinged rod 11 is hinged between the four sliding rods 6 and the test bench 12 .

[0031] The top of each sliding rod 6 is fixedly connected to a first hinge seat 10. The four sides of the bottom surface of the test bench 12 are fixedly connected to second hinge seats 13, and the first hinge seats 10 and the second hinge seats 13 correspond to each other. One end of the hinge rod 11 is rotatably connected to the first hinge seat 10, and the other end of the hinge rod 11 is rotatably connected to the corresponding second hinge seat 13. Both ends of the hinge rod 11 can rotate.

[0032] Two clamping seats are detachably mounted on the test bench 12. Two spring rods 19 are symmetrically fixedly connected to the top of each clamping seat, and a clamping plate 23 is rotatably arranged between the two corresponding spring rods 19, and the clamping plate 23 is arranged in a stepped shape.

[0033] The clamping seat includes a connecting rod 15, which is arranged vertically. The top of the connecting rod 15 is fixedly connected to an L-shaped support frame 18, and two spring rods 19 on the clamping seat are symmetrically fixedly connected to one side of the top of the support frame 18, and each spring rod 19 is arranged horizontally. One end of the clamping plate 23 is rotatably arranged at one end of the corresponding two spring rods 19 away from the support frame 18. The clamping plate 23 can rotate between the two spring rods 19.

[0034] Two groups of mounting holes are provided on the test bench 12, and the two groups of mounting holes are symmetrical about the middle of the test bench 12. Each group of mounting holes includes a plurality of threaded holes 14 distributed in an array.

[0035] The bottom of the connecting rod 15 is fixedly connected with a screw rod 16 adapted to the threaded hole 14, and each threaded hole 14 can be threadedly connected with a screw rod 16, and a locking nut 17 is sleeved on the screw rod 16. After the bottom of the screw rod 16 is rotated into the threaded hole 14, the locking nut 17 is rotated downward to make the locking nut 17 abut against the upper surface of the test bench 12 to fix the connecting rod 15.

[0036] Each spring rod 19 is composed of a sleeve 191, a first spring and a slide bar 192. One end of the sleeve 191 is fixedly connected to the support frame 18, and one end of the slide bar 192 is slidably arranged in the sleeve 191. One end of the first spring is fixedly connected to the inside of the sleeve 191, and the other end of the first spring is fixedly connected to one end of the slide bar 192. One end of the slide bar 192 is positioned in the sleeve 191 by the first spring. The clamping plate 23 is rotatably arranged between the two slide bars 192. When in use, the slide bar 192 is pushed by the clamping plate 23, so that the slide bar 192 slides into the inside of the sleeve 191 and compresses the first spring, and the clamping plate 23 clamps the tablet computer by the elastic force of the first spring.

[0037] Each spring rod 19 is provided with a positioning member for positioning the clamping plate 23 .

[0038] The positioning member includes two limit rods 22 and an insertion rod 20. The two ends of the connection between the clamping plate 23 and the slide rod 192 are fixedly connected with a connecting tube 30, and the connecting tube 30 is rotatably connected to the corresponding slide rod 192. The clamping plate 23 and the slide rod 192 are connected by the connecting tube 30, and when the clamping plate 23 rotates, the connecting tube 30 will be driven to rotate on the corresponding slide rod 192.

[0039] Two positioning holes are provided on the connecting tube 30 and the corresponding sliding rod 192 , and the positioning holes on the connecting tube 30 and the sliding rod 192 correspond to each other one by one.

[0040] A disc is provided at one side of the connection between the slide bar 192 and the connecting tube 30, and two limit rods 22 and one insertion rod 20 are fixedly connected to one side of the disc. The two limit rods 22 are respectively slidably arranged in the corresponding positioning holes, and the limit rods 22 pass through the positioning holes on the slide bar 192 and then extend into the positioning holes of the connecting tube 30. The insertion rod 20 slides through the slide bar 192.

[0041] One end of the insertion rod 20 is slidably disposed in the corresponding connecting tube 30, and one end of the insertion rod 20 extending into the connecting tube 30 is fixedly connected to the second spring 21, and the other end of the second spring 21 is fixedly connected to the inner wall of the connecting tube 30. In the initial state, the second spring 21 pulls one end of the insertion rod 20, and the second spring 21 is in a stretched state, so that the disc abuts against the sliding rod 192, and one end of the limiting rod 22 is inserted into the positioning hole of the connecting tube 30, and the position of the connecting tube 30 is fixed by the limiting rod 22, thereby positioning the clamping plate 23 between the two spring rods 19.

[0042] A handle 28 is fixedly connected to the other side of the disc, and the disc can be moved by the handle 28, thereby driving the insertion rod 20 and the limiting rod 22 to move.

[0043] A testing device is arranged above the base 1 , and the testing device is located directly above the testing table 12 .

[0044] The test device includes a test needle 27. The test needle 27 is a test probe, which is mainly used to test the sensitivity of the touch screen to ensure the response accuracy and stability of the touch screen under various operations. The test needle 27 is also recorded in patent CN113295893B, which is a prior art and will not be described in detail here.

[0045] A display screen 2 and a button 3 are provided on one side of the base 1, and both the display screen 2 and the button 3 are electrically connected to the test pin 27. The test pin 27 is operated by the button 3 to perform a test, and the display screen 2 is used to display the test result.

[0046] The top of the base 1 is fixedly connected with an inverted U-shaped gantry 24, the top of the gantry 24 is slidably provided with a sliding member 25, the bottom of the sliding member 25 is fixedly connected with an electric telescopic rod 26, and the test needle 27 is fixedly connected to the bottom end of the piston rod at the output end of the electric telescopic rod 26. The sliding member 25 can be driven by a cylinder to slide on the gantry 24, which is not the focus of the technical solution to be protected by this application, so it will not be described in detail. By sliding the sliding member 25 on the gantry 24, the electric telescopic rod 26 pushes the test needle 27 up and down, and the position of the test needle 27 can be adjusted so that the test needle 27 can test the tablet computer.

[0047] Working principle: If a tablet computer with a larger volume is tested, the handle 28 is pulled to drive the disk to move. The disk is moved away from one side of the slide bar 192, and the disk drives the insertion rod 20 and the limiting rod 22 to move together. One end of the insertion rod 20 slides in the connecting tube 30 and stretches the second spring 21. The limiting rod 22 slides in the positioning hole.

[0048] Until the limiting rod 22 leaves the connecting tube 30, the clamping plate 23 can be rotated. The clamping plate 23 is rotated upward so that one end of the clamping plate 23 away from the connecting tube 30 is located above the spring rod 19, and the distance between the two clamping plates 23 increases.

[0049] After adjusting the position of the clamping plate 23, release the handle 28, and the second spring 21 will pull the insertion rod 20 to move, so that the disc and the two limiting rods 22 move together. The two limiting rods 22 move into the positioning holes on the connecting tube 30 until the disc abuts against one side of the sliding rod 192. At this time, the two limiting rods 22 fix the position of the connecting tube 30, and then fix the position of the clamping plate 23.

[0050] If a tablet computer with a smaller volume is tested, the limiting rod 22 is slid out of the connecting tube 30, and the clamping plates 23 can be rotated downward, so that the distance between the two clamping plates 23 is reduced.

[0051] To move the tablet computer, first move the tablet computer downward as a whole, and when the tablet computer moves to a suitable step between the two clamping plates 23, place one side of the tablet computer at the step of one of the clamping plates 23, and then squeeze the clamping plate 23 to shrink the corresponding spring rod 19. At this time, one side of the tablet computer abuts against one of the clamping plates 23.

[0052] Afterwards, the other side of the tablet computer is placed on the corresponding step on the other clamping plate 23. Gradually loosen the tablet computer, and under the effect of the spring rod 19, the two clamping plates 23 clamp and fix the tablet computer.

[0053] If the height of the test bench 12 needs to be adjusted, the rotating disk 7 is moved by the vertical lines 9 to rotate the rotating disk 7 on the top surface of the base 1 , and the rotating shaft rotates in the positioning groove 29 at the same time.

[0054] The rotating disk 7 drives the inclined slot 8 to rotate, and the inclined slot 8 pushes the sliding rod 6. Due to the limitation of the limiting block 5, the sliding rod 6 slides along the limiting slot 4, and the limiting block 5 also slides in the limiting slot 4. Then, the four sliding rods 6 are moved closer to or away from each other by the rotation of the rotating disk 7.

[0055] The sliding rod 6 drives the first hinge seat 10 to move, and the first hinge seat 10 pulls the bottom end of the hinge rod 11, so that the top end of the hinge rod 11 pushes the test bench 12 upward or downward through the second hinge seat 13, thereby adjusting the height of the test bench 12 to suit workers of different heights.

[0056] After the adjustment is completed, the tablet touch screen is tested through the test pin 27.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
