Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of touch screen drying, and particularly relates to a drying device for touch screen production. Background Art
[0002] A touch screen refers to a touch screen installed at the front end of a display that is touched with a finger or other object, and then the system locates and selects information input according to the icon or menu position touched by the finger. The touch screen consists of a touch detection component and a touch screen controller;
[0003] During the production process of a touch screen, drying is an important step, especially when coating, bonding, or encapsulation steps are involved in the manufacturing process. The main purpose of drying the touch screen is to remove moisture or solvents in the coating or adhesive, promote the curing of materials, and ensure the flatness and quality of the touch screen;
[0004] Regarding the drying equipment in touch screen production, dryers or ovens with temperature control and precise time management are usually used. These devices can ensure that the touch screen is subjected to uniform and appropriate temperature treatment during the drying process, thus avoiding problems such as overheating, deformation, or damage;
[0005] However, most of the existing drying devices are of a closed structure. The general steps are as follows: place the touch screen in the oven, close the oven, wait for drying, open the oven, and take out the touch screen. Repeated drying requires repeating the above steps;
[0006] First of all, in the above drying method, the equipment is in a stopped state during the opening process of the box body. In order to facilitate the taking out of the touch screen, the box door is generally large. After the box door is opened, the temperature inside the box body will quickly drop. During the process of taking out and re - placing, the temperature inside the oven is almost the same as the outside. When drying again, the oven needs to be heated again, which obviously increases energy consumption and requires re - heating, thus prolonging the drying time. Secondly, after the touch screen enters the oven, it needs to wait for drying. Therefore, in actual use, multiple ovens need to be purchased to coordinate the time difference, which obviously increases the cost of the drying process;
[0007] To solve the above problems, a drying device for touch screen production is proposed in this application. Summary of the Utility Model
[0008] The purpose of the utility model is to provide a drying device for touch screen production, which solves the problems raised in the above background art.
[0009] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0010] The utility model relates to a drying device for touch screen production, which comprises a drying box. The drying box is circularly arranged and has a cavity formed inside. A notch communicating with the cavity is formed on the drying box. A turntable is arranged at the bottom of the cavity of the drying box. A driving mechanism for driving the turntable to rotate is arranged on the drying box. A drying mechanism capable of circulating air inside it is arranged in the drying box. A self-rotation mechanism is arranged between the inner side of the drying box and the upper end of the turntable. A clamping mechanism is arranged at the upper end of the turntable through the self-rotation mechanism. Supporting feet are fixed at the bottom of the drying box.
[0011] Further, the drying mechanism comprises a base fixed in the drying box and an arc-shaped air outlet pipe formed in the base.

The arc-shaped air outlet pipe and the vertical air inlet pipe are both in two symmetrical groups, and the side surface of the arc-shaped air outlet pipe and the upper end of the vertical air inlet pipe communicate with the inside of the drying box.
[0012] Further, the drying mechanism further comprises two fans fixed at both ends of the vertical air inlet pipe and a heating wire fixed in the vertical air inlet pipe and located between the two fans.
[0013] Further, the self-rotation mechanism comprises a self-rotating disc rotatably installed on the turntable and a partial gear fixed on the inner side wall of the drying box and meshing with the self-rotating disc. The self-rotating disc and the partial gear are meshed through the rotation of the turntable inside the drying box.
[0014] Further, the clamping mechanism comprises a fixing seat fixed at the upper end of the self-rotating disc, clamping seats symmetrically distributed at the upper end of the fixing seat and slidable, and clamping plates elastically connected to the clamping seats. The clamping plates are arranged in an "L" shape. A linear guide rod penetrating and sliding in the clamping seat is fixed on the outer side of the clamping plate. A clamping spring for clamping the touch screen is arranged between the linear guide rod and the clamping seat.
[0015] Further, the fixing seat and the clamping seat are slidably installed through a slide rail. An internally threaded block is fixed at the bottom of the clamping seat. A bidirectional lead screw screwed to the internally threaded block is rotatably arranged on the fixing seat.
[0016] Further, the driving mechanism comprises a driven gear ring fixed at the bottom of the turntable and located below the drying box and a motor installed on the drying box. A driving gear meshing with the driven gear ring is fixed at the output end of the motor.
[0017] The utility model has the following beneficial effects:
[0018] By arranging the rotating turntable in cooperation with the drying mechanism, the drying mechanism can form a circulating heating air flow channel inside the drying box, and then cooperate with the rotation and feeding of the turntable to realize the continuous drying of the touch screen, carry out loading and unloading and drying at the same time, improve the drying efficiency, and at the same time, the equipment does not need to stop when there is no fault, effectively avoiding heat loss.
[0019] The utility model is provided with a rotation mechanism that cooperates with the rotation of the turntable, and then a clamping mechanism that cooperates with the turntable is provided. The clamping mechanism can be adjusted, so as to facilitate the clamping of touch screens of different models. At the same time, the clamping mechanism can also quickly clamp and remove the touch screen through the clamping plate and the clamping spring, ensuring the working efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.
[0030] Please refer to Figures 1-4 As shown, the present utility model is a drying device for touch screen production, including a drying box 1. The drying box 1 is circularly arranged and a cavity is formed inside. A notch communicating with the cavity is opened on the drying box 1. A turntable 2 is provided at the bottom of the cavity of the drying box 1. A driving mechanism 7 for driving the turntable 2 to rotate is provided on the drying box 1. A drying mechanism 3 capable of circulating air inside is provided in the drying box 1. A self-rotation mechanism 5 is arranged between the inner side of the drying box 1 and the upper end of the turntable 2. A clamping mechanism 6 is arranged on the upper end of the turntable 2 through the self-rotation mechanism 5. Supporting feet 4 are fixed at the bottom of the drying box 1.
[0031] Among them, the drying mechanism 3 includes a base 31 fixed in the drying box 1 and an arc-shaped air outlet pipe 32 formed in the base 31. A vertical air inlet pipe 33 communicating with the arc-shaped air outlet pipe 32 is also formed in the base 31. Both the arc-shaped air outlet pipe 32 and the vertical air inlet pipe 33 are in two symmetrical groups. The side of the arc-shaped air outlet pipe 32 and the upper end of the vertical air inlet pipe 33 communicate with the inside of the drying box 1. In this embodiment, by setting the arc-shaped air outlet pipe 32 and the vertical air inlet pipe 33 in two symmetrical groups, after the two airflows are discharged from the arc-shaped air outlet pipes 32 in two directions, they finally collide above the vertical air inlet pipe 33. At this time, the airflow formed by the operation of the fan 34 follows the cycle again, having the advantages of good circulation and drying effects and less heat loss. At the same time, it will not affect the loading and unloading at the notch position of the drying box 1.
[0032] Among them, the drying mechanism 3 further includes two blowers 34 fixed at both ends of the vertical air inlet pipe 33 and a heating wire 35 fixed in the vertical air inlet pipe 33 and located between the two blowers 34. In this embodiment, the two blowers 34 drive the air flow to enter from the top opening of the vertical air inlet pipe 33 and flow downward through the arc-shaped air outlet pipe 32. The air flow flows out of the arc-shaped air outlet pipe 32 in a direction of flowing back toward the upper end of the vertical air inlet pipe 33. Along the internal path of the drying box 1, the air flow will flow through the vertical air inlet pipe 33 and the arc-shaped air outlet pipe 32 again. The arranged heating wire 35 can clamp the flowing gas, so as to achieve the purpose of drying the touch screen.
[0033] Among them, the self-rotation mechanism 5 includes a self-rotating disk 51 rotatably installed on the turntable 2 and a partial gear 52 fixed on the inner side wall of the drying box 1 and meshing with the self-rotating disk 51. The self-rotating disk 51 and the partial gear 52 are rotationally meshed through the rotation of the turntable 2 inside the drying box 1. In this embodiment, on the basis of the turntable 2 driving the clamping mechanism 6 to revolve, the self-rotation is realized through the self-rotation mechanism 5, which has the effect of improving the drying uniformity of the touch screen.
[0034] Among them, the clamping mechanism 6 includes a fixed seat 63 fixed at the upper end of the self-rotating disk 51, clamping seats 61 symmetrically distributed at the upper end of the fixed seat 63 and slidable, and clamping plates 62 elastically connected to the clamping seats 61. The clamping plates 62 are arranged in an "L" shape. A linear guide rod 67 penetrating and sliding in the clamping seat 61 is fixed on the outer side of the clamping plate 62. A clamping spring 68 for clamping the touch screen is arranged between the linear guide rod 67 and the clamping seat 61. In this embodiment, by arranging the elastic clamping plates 62 on the adjustable clamping seats 61, the clamping spring 68 can realize the quick clamping and loosening of the touch screen, which can not only ensure the stability during drying, but also facilitate the loading and unloading work.
[0035] Among them, the fixed seat 63 and the clamping seat 61 are slidably installed through a slide rail 64. An internally threaded block 65 is fixed at the bottom of the clamping seat 61. A bidirectional lead screw 66 screwed to the internally threaded block 65 is rotatably provided on the fixed seat 63. In this embodiment, through the cooperation of the internally threaded block 65 and the bidirectional lead screw 66, the distance between the two clamping seats 61 can be adjusted, so as to adapt to the clamping of touch screens of different sizes, and further make this drying device have better adaptability and practicability.
[0036] Among them, the driving mechanism 7 includes a driven gear ring 71 fixed at the bottom of the turntable 2 and located below the drying box 1 and a motor 72 installed on the drying box 1. A driving gear 73 meshing with the driven gear ring 71 is fixed at the output end of the motor 72. In this embodiment, the motor 72 is fixed to the bottom of the drying box 1 through a bracket. The contact surfaces of the turntable 2 with the drying box 1 and the drying mechanism 3 can adopt rolling connections, which can reduce the noise generated when the turntable 2 rotates.
[0037] It can be understood that, first, a drying box forms a circular channel and is provided with a rotating turntable, which can realize the continuous feeding and discharging of the touch screen. Then, a drying mechanism for circulating heat is arranged in the circular channel, which can effectively dissipate heat while the touch screen is being conveyed. Secondly, the clamping mechanism arranged can adapt to the clamping of touch screens of different sizes and ensure the stability of the touch screen during drying. Finally, the self-rotation mechanism arranged can drive the independent touch screen to rotate while the turntable revolves, thereby improving the drying uniformity of the touch screen.
[0038] A specific application of this embodiment is as follows:
[0039] The working state of the drying mechanism 3 is as follows: As Figure 3 shown, the air flow generated by the operation of the two fans 34 in each vertical air inlet pipe 33 all flows downward. After the air flow passes through the arc-shaped air outlet pipe 32, it flows upward along the side wall of the drying box 1, and then enters the vertical air inlet pipe 33 and the arc-shaped air outlet pipe 32 again under the action of the fan 34, thereby realizing circulation. The heating wire 35 in the vertical air inlet pipe 33 heats the circulating gas to dry the touch screen located on the turntable 2;
[0040] During actual use, first adjust the clamping mechanism 6 according to the size of the touch screen. After rotating the bidirectional lead screw 66, the spiral drive with the internal thread block 65 drives the clamping seats 61 and the clamping plates 62 at both ends to slide synchronously in opposite directions. Place the touch screen between the two clamping plates 62, and then clamp the touch screen under the action of the clamping spring 68. A notch is provided on the drying box 1, and this notch can accommodate two groups of clamping mechanisms 6 at the same time, providing sufficient space for loading and unloading.
[0041] The motor 72 outputs and drives the turntable 2 to rotate inside the drying box 1 through the driving gear 73 and the driven gear ring 71. The turntable 2 drives all the clamping mechanisms 6 to revolve. After the clamping mechanism 6 enters the inside of the drying box 1, the self-rotation disk 51 meshes with the partial gear 52 to drive the clamping mechanism 6 and the touch screen at its upper end to rotate. During the rotation of the touch screen inside the drying box 1, it is dried through the heat channel formed by the drying mechanism 3, and finally returns to the notch position. The staff removes the dried touch screen and places the touch screen to be dried again.
