Description

Technical Field

[0001] This utility model relates to the field of touch screen manufacturing technology, specifically to a positioning mechanism for touch screen manufacturing. Background Technology

[0002] A touch screen, also known as a "touchscreen" or "touch panel," is a sensor-type liquid crystal display device that can receive input signals from touch points. Touch screens require manual fixing in the later stages of production for inspection and fastening, necessitating the use of a dedicated positioning mechanism.

[0003] A search revealed a Chinese patent publication dated March 4, 2022, with publication number CN215942708U, describing a positioning mechanism for touchscreen production. The mechanism includes an operating table with a geared disc fixed to its upper part. A positioning plate is rotatably connected to the upper part of the geared disc. The positioning plate has a hollow interior, with symmetrical slots at the four corners of its upper part. A column is slidably inserted into each slot, and a horizontal bar is fixed to the upper end of each column. A right-angle positioning block is fixed to the end of the horizontal bar away from the column. A movable clamping mechanism is provided within the positioning plate, and a placement plate is fixed to the middle of its upper part. A rotating locking mechanism is provided between the positioning plate and the geared disc. This invention is adaptable to touchscreens of different sizes and provides better fixation by locking the four corners of the touchscreen, preventing it from falling off. It is easy to operate, allows free rotation, and incorporates a locking and releasing mechanism based on user habits, making its design reasonable.

[0004] While the aforementioned existing technical solutions can adapt to touchscreens of different sizes and clamp the four corners of the touchscreen to achieve a better fixing effect and prevent it from falling off, the angle of the strip groove is fixed. Therefore, the device can only clamp and fix touchscreens of different sizes but the same length-width ratio, and cannot clamp and fix touchscreens of different length-width ratios, resulting in low device adaptability. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a positioning mechanism for touch screen production, which solves the problem in the background technology that it can only clamp and fix touch panels of different sizes but the same length-width ratio, but cannot clamp and fix touch panels of different length-width ratios, resulting in low equipment adaptability.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for touch screen production, comprising a worktable and two control slots. A central shaft is fixedly connected to the top of the worktable, and a positioning seat is provided at the top of the central shaft. A sliding groove is provided on the lower inner side wall of the positioning seat. Two corresponding sliding sleeves are slidably connected inside the sliding groove. Sliding plates are slidably connected to both ends of the two sliding sleeves. Connecting rods are fixedly connected to the tops of the four sliding plates at positions away from the sliding sleeves. An angle clamp is fixedly connected to the tops of the four connecting rods. The two control slots are slidably connected to the two connecting rods respectively. A first bidirectional threaded rod and a second bidirectional threaded rod are rotatably connected to the inner side wall of the positioning seat. The first bidirectional threaded rod is threadedly connected to the two sliding sleeves, and the second bidirectional threaded rod is threadedly connected to the two control slots. One end of the first bidirectional threaded rod and the second bidirectional threaded rod both penetrate the positioning seat and are connected to a handle. Four cooperating support rods are fixedly connected to the lower inner side wall of the positioning seat, and placement plates are fixedly connected to the tops of the four support rods.

[0009] By adopting the above technical solution, the workpiece is placed on the placement plate, and the first bidirectional threaded rod is rotated to drive the two sliding sleeves to move, thereby driving the sliding plate, connecting rod and corner clamp to move along the control groove. The second bidirectional threaded rod is rotated to drive the two control grooves to move, thereby driving the sliding plate, connecting rod and corner clamp to move along the sliding sleeve. This facilitates the clamping and fixing of touch panels with different length and width ratios, thereby improving the equipment adaptability.

[0010] Optionally, each of the four corner clamps has a bottom support fixedly connected to its inner sidewall near the bottom.

[0011] By adopting the above technical solution, the bottom support is used to support the bottom of the four corners of the touch screen when the device clamps and fixes the touch screen, so as to prevent the touch screen from tilting and thus improve the stability of the touch screen.

[0012] Optionally, buffer pads are provided on the inner sidewalls of the four corner clamps.

[0013] By adopting the above technical solution, the buffer pad is used to provide cushioning between the corner clamp and the touch screen when the device clamps and fixes the touch screen, thereby reducing the probability of the corner clamp causing squeezing damage to the touch screen.

[0014] Optionally, the positioning seat is rotatably connected to the central shaft, and a support ring is fixedly connected to the bottom end of the positioning seat. An external toothed ring is provided on the outer wall of the support ring. A fixing block is fixedly connected to the top end of the worktable, and a sliding rod is slidably connected to the fixing block. An arc-shaped toothed block that meshes with the external toothed ring is fixedly connected to one end of the sliding rod, and a spring is provided between the arc-shaped toothed block and the fixing block.

[0015] By adopting the above technical solution, the support ring is used to support the positioning seat and prevent the positioning seat from shaking or tilting. Pulling the sliding rod causes the arc-shaped toothed block to disengage from the outer toothed ring. At this time, the positioning seat can be rotated to adjust the direction of the touch screen. The spring is used to push the arc-shaped toothed block and the sliding rod to move, so that the arc-shaped toothed block meshes with the outer toothed ring, thereby positioning the positioning seat, so as to facilitate the processing or inspection of different positions of the touch screen.

[0016] Optionally, the bottom end of the support ring is rotatably connected to a plurality of evenly distributed ball bearings.

[0017] By adopting the above technical solution, the ball bearings are used to reduce the friction between the support ring and the worktable, thereby improving the smoothness of equipment operation.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This positioning mechanism for touch screen production places the workpiece on a placement plate. Rotating the first bidirectional threaded rod moves two sliding sleeves, thereby moving the sliding plate, connecting rod, and corner clamp along the control groove. Rotating the second bidirectional threaded rod moves two control grooves, thereby moving the sliding plate, connecting rod, and corner clamp along the sliding sleeve. This facilitates the clamping and fixing of touch panels with different length-to-width ratios, thereby improving the adaptability of the equipment. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 A positioning mechanism for touchscreen production includes a worktable 1, comprising two control slots 2. A central shaft is fixedly connected to the top of the worktable 1, and a positioning seat 3 is provided at the top of the central shaft. A sliding groove 4 is formed on the lower inner side wall of the positioning seat 3. Two corresponding sliding sleeves 5 are slidably connected inside the sliding groove 4. Sliding plates 6 are slidably connected to both ends of the two sliding sleeves 5. Connecting rods 7 are fixedly connected to the tops of the four sliding plates 6 at positions away from the sliding sleeves 5. An angle clamp 8 is fixedly connected to the tops of the four connecting rods 7. The two control slots 2 are slidably connected to the two connecting rods 7 respectively. A first bidirectional threaded rod 9 and a second bidirectional threaded rod 10 are rotatably connected to the inner side wall of the positioning seat 3. The first bidirectional threaded rod 9 is threadedly connected to the two sliding sleeves 5, and the second bidirectional threaded rod 10 is rotatably connected to the two sliding sleeves 5. The threaded rod 10 is threadedly connected to two control slots 2. One end of the first bidirectional threaded rod 9 and the second bidirectional threaded rod 10 both pass through the positioning seat 3 and are connected to a handle. Four cooperating support rods 11 are fixedly connected to the inner lower side wall of the positioning seat 3. The top of the four support rods 11 is fixedly connected to a placement plate 12. When the workpiece is placed on the placement plate 12, rotating the first bidirectional threaded rod 9 drives the two sliding sleeves 5 to move, thereby driving the sliding plate 6, connecting rod 7 and corner clamp 8 to move along the control slot 2. Rotating the second bidirectional threaded rod 10 drives the two control slots 2 to move, thereby driving the sliding plate 6, connecting rod 7 and corner clamp 8 to move along the sliding sleeves 5. This facilitates the clamping and fixing of touch panels with different length and width ratios, thereby improving the adaptability of the equipment.

[0029] Reference Figure 1 and Figure 2 Each of the four corner clamps 8 has a bottom support 13 fixedly connected to its inner side wall near the bottom. The bottom support 13 is used to support the bottom of the four corners of the touch screen when the device clamps and fixes the touch screen, so as to prevent the touch screen from tilting and thus improve the stability of the touch screen.

[0030] Reference Figure 1 and Figure 2Each of the four corner clamps 8 has a buffer pad 14 on its inner sidewall. The buffer pad 14 is used to provide buffer between the corner clamps 8 and the touch screen when the device clamps and fixes the touch screen, thereby reducing the probability of the corner clamps 8 causing squeezing damage to the touch screen.

[0031] Reference Figure 3 and Figure 4 The positioning seat 3 is rotatably connected to the central shaft. A support ring 15 is fixedly connected to the bottom end of the positioning seat 3. An external toothed ring 16 is provided on the outer wall of the support ring 15. A fixed block 17 is fixedly connected to the top end of the worktable 1. A sliding rod 18 is slidably connected to the fixed block 17. An arc-shaped toothed block 19 that meshes with the external toothed ring 16 is fixedly connected to one end of the sliding rod 18. A spring 20 is provided between the arc-shaped toothed block 19 and the fixed block 17. The support ring 15 is used to support the positioning seat 3 to prevent the positioning seat 3 from shaking or tilting. Pulling the sliding rod 18 causes the arc-shaped toothed block 19 to disengage from the external toothed ring 16. At this time, the positioning seat 3 can be rotated to adjust the direction of the touch screen. The spring 20 is used to push the arc-shaped toothed block 19 and the sliding rod 18 to move, so that the arc-shaped toothed block 19 meshes with the external toothed ring 16, thereby positioning the positioning seat 3, so as to facilitate the processing or inspection of different positions of the touch screen.

[0032] Reference Figure 3 and Figure 4 The bottom end of the support ring 15 is rotatably connected with a number of evenly distributed balls 21. The balls 21 are used to reduce the friction between the support ring 15 and the worktable 1, thereby improving the smoothness of equipment operation.

[0033] In summary, the working principle and process of the positioning mechanism for touch screen production are as follows: First, the workpiece is placed on the placement plate 12. Rotating the first bidirectional threaded rod 9 moves the two sliding sleeves 5, thereby moving the sliding plate 6, connecting rod 7, and corner clamping member 8 along the control groove 2. Rotating the second bidirectional threaded rod 10 moves the two control grooves 2, thereby moving the sliding plate 6, connecting rod 7, and corner clamping member 8 along the sliding sleeves 5. This facilitates the clamping and fixing of touch panels with different length-to-width ratios, improving equipment adaptability. The bottom support 13 supports the bottom of the four corners of the touch screen during clamping and fixing, preventing tilting and improving stability. The buffer pad 14 is used for... When the device clamps and fixes the touch screen, a buffer is provided between the corner clamp 8 and the touch screen to reduce the probability of the corner clamp 8 causing squeezing damage to the touch screen. The support ring 15 is used to support the positioning seat 3 to prevent the positioning seat 3 from shaking or tilting. Pulling the sliding rod 18 causes the arc-shaped toothed block 19 to disengage from the outer toothed ring 16. At this time, the positioning seat 3 can be rotated to adjust the direction of the touch screen. The spring 20 is used to push the arc-shaped toothed block 19 and the sliding rod 18 to move, so that the arc-shaped toothed block 19 meshes with the outer toothed ring 16, thereby positioning the positioning seat 3, so as to facilitate the processing or inspection of different positions of the touch screen. The ball 21 is used to reduce the friction between the support ring 15 and the worktable 1, thereby improving the smoothness of the device operation.
