Technical Field

[0001] The utility model relates to the technical field of touch screen production, in particular to a positioning device for touch screen production and attachment. Background Art

[0002] Touch screen technology is the most acceptable computer input method for ordinary people after keyboard, mouse, handwriting board and voice input. With this technology, users can operate the host computer by simply touching the icons or text on the computer screen with their fingers, making human-computer interaction more straightforward. This technology greatly facilitates users and is a very attractive new multimedia interactive device.

[0003] In the prior art, a touch screen is usually formed by stacking multiple components such as a protective layer, a light-emitting layer, and a filter layer together and then pressing them together. Adhesive is also filled between the multiple components for fixation. There is still space between the touch screens before pressing, which will cause errors after the components are stacked and affect the pressing effect. Utility Model Content

[0004] According to the shortcomings of the prior art, the purpose of the present invention is to provide a positioning device for touch screen production and attachment, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A positioning device for touch screen production and attachment comprises a base, wherein a motor is fixedly connected to the bottom center of the base, an output shaft of the motor is connected to a feed unit via a transmission unit, a slide groove is provided on the top of the base, and a push plate matched with the feed unit is connected in the slide groove.

[0007] By adopting the above technical solution, the operation of all feeding units can be synchronously controlled by the set transmission unit, and then the push plate can be brought close to the center of the base. The stacked touch screen elements can be pushed to the center of the base through the synchronous movement of the push plate, and then the edges of multiple touch screen elements can be kept flush through the squeezing of the push plate, so that no error will occur when the touch screen is pressed, thereby improving the quality of the touch screen.

[0008] In a preferred example, the utility model can be further configured as follows: the transmission unit includes a driving gear and a driven gear, a circular groove is opened in the middle of the base, a driving gear is arranged at the bottom of the circular groove, the bottom of the driving gear is fixedly connected to the output shaft of the motor, and four driven gears are arranged at equal intervals on the top of the driving gear, and the four driven gears are all meshed with the driving gear.

[0009] By adopting the above technical solution, the rotation of the set active gear can simultaneously drive multiple driven gears to operate, so that each driven gear synchronously controls the movement of the corresponding feed unit, so that the push plate is close to the center of the base, and the touch screen is moved to the middle of the base to wait for hot pressing.

[0010] In a preferred example, the utility model can be further configured as follows: the feeding unit includes a screw, a slider and an electromagnet, one end of the screw is fixedly connected to the driven gear, the outer wall of the screw is sleeved with a slider, a ball is rollingly arranged in the slider and contacts with the spiral groove of the screw, an electromagnet is embedded in the top of the slider, and a permanent magnet that attracts the electromagnet is embedded in the push plate.

[0011] By adopting the above technical solution, the permanent magnet and the electromagnet are arranged to cooperate, so that when the slider moves due to the rotation of the screw, the push plate is pushed forward by the magnetic force, and when the touch screen is pushed to the center and cannot move further, the push plate and the slider are disconnected, effectively preventing the push plate from excessively squeezing the touch screen and causing the touch screen to break.

[0012] In a preferred example, the utility model can be further configured as follows: a support plate portion is formed on a protrusion on one side of the push plate close to the center of the base, and the top surface of the support plate portion is flush with the top surface of the base.

[0013] By adopting the above technical solution, the support plate portion is provided to provide support for the touch screen during hot pressing after the touch screen is positioned, so as to avoid the bottom side of the touch screen being suspended in the air, resulting in poor hot pressing effect.

[0014] In a preferred example, the utility model can be further configured as follows: a buffer pad is fixedly connected to one side of the push plate above the support plate portion, and the corners of the top of the push plate close to one side of the support plate portion are processed into bevels.

[0015] By adopting the above technical solution, the push plate can be in flexible contact with the edge of the touch screen through the provided buffer pad, and the provided bevel angle can avoid the heat press when the heat press presses the touch screen.

[0016] In a preferred example, the utility model can be further configured as follows: a plurality of second balls are evenly distributed on the bottom of the push plate, and a gap for the second balls to roll is reserved between the bottom of the push plate and the inner bottom wall of the slide groove.

[0017] By adopting the above technical solution, the setting of ball bearing 2 can reduce the friction force generated when the push plate is pulled by magnetic force, making the movement of the push plate more flexible. In addition, the setting of ball bearing 2 can reduce the sliding wear of the push plate and increase the service life of the push plate.

[0018] In summary, the utility model includes at least one of the following beneficial technical effects:

[0019] 1. A positioning device for production and attachment of a touch screen can make multiple push plates move synchronously through the cooperation of a transmission unit and a feeding unit. The synchronous movement of the push plates can push the stacked touch screen elements to the center of the base. Then, the edges of the multiple touch screen elements can be kept flush through the extrusion of the push plates, so that there will be no error when the touch screen is pressed together, thereby improving the quality of the touch screen. Moreover, by connecting the feeding unit and the push plate to each other through magnetic force, when the push plate pushes the touch screen to the middle of the base and cannot continue to push, the push plate is disconnected from the slider, thereby effectively preventing the push plate from excessively extruding the touch screen and causing the touch screen to break.

[0020] 2. This positioning device for touch screen production and attachment can provide support for the touch screen during hot pressing through the provided support plate part to avoid the edge of the touch screen hanging in the air, which will cause the hot pressing effect to deteriorate.

[0021] 3. This positioning device for touch screen production and attachment can reduce the friction generated when the push plate is pulled by the magnetic force by the setting of the second ball, making the movement of the push plate more flexible. The setting of the second ball can also reduce the sliding wear of the push plate and increase the service life of the push plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0028] Reference Figure 1 - Figure 3 The utility model discloses a positioning device for touch screen production and attachment, including a base 1, a motor 2 is fixedly connected to the bottom center of the base 1, the output shaft of the motor 2 is connected to a feeding unit 4 through a transmission unit 3, a slide groove 5 is opened on the top of the base 1, and a push plate 6 matched with the feeding unit 4 is connected in the slide groove 5.

[0029] In this embodiment, the touch screen components are stacked and placed on the base 1, and then the motor 2 is started, and the motor 2 drives the driving gear 31 to rotate, so that the multiple driven gears 32 run synchronously. Figure 2 It can be found that each driven gear 32 is individually connected to a feed unit 4, so when the driven gear 32 rotates, the corresponding screw 41 will rotate, causing the corresponding slider 42 to move along the axis of the screw 41, and the top of the slider 42 is connected to an electromagnet 43, which attracts the permanent magnet 9 through the magnetic force of the electromagnet 43, and then pushes the push plate 6 to move in the slide groove 5 through the permanent magnet 9, so that multiple push plates 6 run synchronously, pushing the touch screen to the center of the top of the base 1, and when pushing, the push plate 6 will also squeeze the edge of the touch screen, thereby flattening the edge of the touch screen, keeping the edge of the touch screen horizontal, reducing the error caused by hot pressing of the touch screen, and improving the quality of the touch screen.

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, the transmission unit 3 includes a driving gear 31 and a driven gear 32. A circular groove 7 is opened in the middle of the base 1, and a driving gear 31 is arranged at the bottom of the circular groove 7. The bottom of the driving gear 31 is fixedly connected to the output shaft of the motor 2, and four driven gears 32 are arranged at equal intervals on the top of the driving gear 31. The four driven gears 32 are all meshed with the driving gear 31.

[0031] In this embodiment, since a plurality of push plates 6 for pushing the touch screen are provided on the top of the base 1, in order to position the touch screen at the center of the base 1 and to make the plurality of push plates 6 run synchronously, a driving gear 31 connected to the motor 2 is provided, so that when the motor 2 runs, the rotation of the driving gear 31 drives the plurality of driven gears 32 to rotate synchronously, thereby achieving the synchronous operation of the plurality of push plates 6, so that the push plates 6 can position the touch screen at the top center of the base 1.

[0032] In a further preferred embodiment of the present invention, Figure 3As shown, the feeding unit 4 includes a screw 41, a slider 42 and an electromagnet 43. One end of the screw 41 is fixedly connected to the driven gear 32. The outer wall of the screw 41 is sleeved with a slider 42. A ball 8 is rolled in the slider 42 and contacts the spiral groove of the screw 41. The top of the slider 42 is embedded with an electromagnet 43, and the push plate 6 is embedded with a permanent magnet 9 that attracts the electromagnet 43.

[0033] In this embodiment, when the motor 2 runs and causes the driven gear 32 to rotate, the screw 41 connected to the driven gear 32 will rotate synchronously, so that the ball bearing 8 is pushed by the rotation of the spiral groove so that the ball bearing 8 drives the slider 42 to move along the axis of the screw 41, and then the push plate 6 moves synchronously, and the touch screen is pushed to the center of the top of the base 1 through the push plate 6.

[0034] The touch screen is formed by stacking and pressing multiple components. Therefore, before hot pressing, the pressure-bearing capacity of each component of the touch screen is poor. If the motor 2 is not stopped in time after the push plate 6 pushes the touch screen to the center of the base 1, the push plate 6 will exert pressure on the touch screen, causing damage to the components of the touch screen. Therefore, the slider 42 is connected to the push plate 6 by magnetic force. Through the magnetic drive, the push plate 6 can push the touch screen normally when it pushes it to the center of the base 1. When the touch screen cannot be pushed further after being pushed to the center, if the motor 2 is not stopped in time, the slider 42 will continue to move with the rotation of the screw 41, but the push plate 6 will be disconnected from the slider 42 because it cannot move forward, thereby preventing the push plate 6 from excessively squeezing the touch screen and causing damage to the touch screen.

[0035] When the slider 42 is disconnected from the push plate 6, the magnetic force of the electromagnet 43 and the magnetic field of the permanent magnet 9 will not disappear, so there is still a certain attraction between them. Therefore, a traction force can be applied to the permanent magnet 9 by the electromagnet 43 to prevent the push plate 6 from loosening after the slider 42 is disconnected, causing the touch screen to deviate from the center of the base 1, thereby effectively ensuring the accuracy of hot pressing.

[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, a support plate portion 10 is formed on one side of the push plate 6 close to the center of the base 1 , and the top surface of the support plate portion 10 is flush with the top surface of the base 1 .

[0037] In this embodiment, in order to prevent the push plate 6 from being offset during movement and affecting the centering of the touch screen, a slide groove 5 is provided to limit the movement of the push plate 6. However, the provision of the slide groove 5 will cause the edge of the touch screen to be suspended in the air. Therefore, when the touch screen is pressed by the hot press, the edge of the touch screen cannot be well pressed due to the suspension, resulting in the deterioration of the quality of the touch screen. Therefore, a support plate portion 10 is provided on the push plate 6 to support the edge of the touch screen, thereby improving the effect of hot pressing and effectively improving the quality of the touch screen.

[0038] In a further preferred embodiment of the present invention, Figure 3 As shown, a buffer pad 11 is fixedly connected to one side of the push plate 6 located above the support plate portion 10 , and the corner of the top of the push plate 6 close to one side of the support plate portion 10 is processed into a bevel 12 .

[0039] In this embodiment, when the push plate 6 pushes the touch screen to the top center of the base 1, because there is still a weak magnetic attraction between the push plate 6 and the slider 42, the push plate 6 will apply a small pressure to the edge of the touch screen. Therefore, a buffer pad 11 is provided to make the contact surface of the push plate 6 and the touch screen in flexible contact, thereby reducing the pressure on the touch screen as much as possible and improving the quality of the touch screen. Subsequently, when the touch screen is pressed by the heat press, in order to achieve a better pressing effect, the effective hot pressing area of ​​the heat press will cover the entire touch screen. Therefore, the push plate 6 in contact with the edge of the touch screen will interfere with the downward pressing of the heat press. Therefore, a bevel 12 is provided on the top of the push plate 6. When the hot press is pressed downward, the push plate 6 slides in the slide groove 5 by squeezing the bevel 12 by the hot press, so that the push plate 6 can avoid the hot press.

[0040] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of balls 13 are evenly distributed on the bottom of the push plate 6 , and a gap for the balls 13 to roll is reserved between the bottom of the push plate 6 and the inner bottom wall of the slide groove 5 .

[0041] In this embodiment, no matter the push plate 6 is pulled by the slider 42 or squeezed by the hot press and slides in the slide groove 5, the push plate 6 will rub against the slide groove 5, which will cause the push plate 6 to wear when moving. Therefore, a ball bearing 13 is arranged at the bottom of the push plate 6 to reduce the wear of the push plate 6 when moving. At the same time, the setting of the ball bearing 13 can also reduce the friction force of the push plate 6 when moving, thereby making it easier for the slider 42 to pull the push plate 6 and improving the response speed of the push plate 6.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
