Description

Technical Field

[0001] The utility model relates to the field related to touch screen production, and in particular to a fully automatic production equipment device for a touch screen exposure process. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program. It can be used to replace mechanical button panels and achieve clear display of the picture through the liquid crystal display.

[0003] The common touch screen is ITO glass touch screen. ITO touch screen technology works by using the current induction of the human body. ITO glass is used as the working surface. When the finger touches the metal layer, due to the electric field of the human body, a coupling capacitor is formed between the user and the touch screen surface. For high-frequency current, the capacitor is a direct conductor, so the finger absorbs a very small current from the contact point. The controller obtains the position of the touch point by accurately calculating the current ratio to perform corresponding actions.

[0004] The overall production steps of ITO touch screens can be generally summarized as cleaning, coating, drying, exposure, development, etching and demoulding, silk screen printing and laser. When the touch screen is exposed, a mask needs to be covered on the glass surface coated with photoresist, and ultraviolet light is selectively irradiated to make the photoresist in the illuminated area react chemically and change the solubility of this part of the film in the developer. For this purpose, exposure equipment is needed.

[0006] The above-mentioned existing exposure equipment lacks certain positioning auxiliary measures when placing materials for exposure to ensure that the material and the exposure lamp correspond to each other up and down, which makes it easier for the placement position to shift, causing errors in material exposure, and further affecting subsequent material processing activities.

[0035] Here’s how it works:

[0036] When the glass substrate 5 is to be exposed, the glass substrate 5 is coated with photoresist in the above step. After coating, it will be transported to the conveyor body 3 provided inside the machine body 1 along with the transport equipment, and can be driven by the motor 4 connected to the right side of the front end of the conveyor body 3 to realize the backward guiding activity. In this way, the glass substrate 5 can be automatically guided backward by the conveyor body 3. When it is guided to the lower end of the mask plate 7 plugged between the mask plates 7 on both sides, the conveyor body 3 is temporarily stopped, and the ultraviolet exposure lamp 8 installed in the middle of the upper end of the front side of the machine body 1 is turned on. Through the cooperation of ultraviolet irradiation and the pattern on the mask plate 7, the photoresist in the illuminated part of the glass substrate 5 will react chemically, that is, the solubility of the photoresist in the illuminated part in the subsequent developer is changed, so that the circuit picture can be displayed on the subsequent glass substrate 5 through the developer. In this way, the glass substrate 5 can complete the exposure activity and be guided backward again along with the conveyor body 3, and introduced into the next processing equipment from the rear side of the machine body 1.

[0037] When the glass substrate 5 is transmitted to the upper end of the conveyor body 3, in order to ensure that the overall position of the glass substrate 5 is centered and the glass substrate 5 corresponds to the mask plate 7 and the ultraviolet exposure lamp 8 in the upper and lower directions, an auxiliary positioning device 9 is also provided on the front side of the machine body 1, that is, by operating the transmission motor 961 of the driving assembly 96 provided on the left side of the lower end of the shell 91, the transmission motor 961 realizes the circumferential rotation of the rotating plate 962 connected to the front side, and as the rotating plate 962 rotates, the connecting rod 963 connected to the front end of the rotating plate 962 rotates, and intermittent push-pull transmission activities are realized, and the fixed block 964 connected to the outer end of the connecting rod 963 cooperates with the connecting frame 931 provided on the left side to realize intermittent reciprocating push-pull, and the left connecting frame 931 reciprocates horizontally, and the rack 932 transversely provided on the right end of the left connecting frame 931 meshes with the gear 92 connected to the lower end of the transmission, so that the gear 92 reciprocates left and right with the right rack 932 The left rack 932 meshing with the bottom of the rack 932 under the clockwise rotation of the gear 92 will be driven to realize the reciprocating transverse movement of the connecting frame 931 on the right side. In this way, the left and right connecting frames 931 will synchronously realize reciprocating relative or opposite movement. Through the synchronous relative or opposite movement of the connecting frames 931 on both sides, the positioning bars 94 correspondingly installed on the upper ends of the connecting frames 931 on both sides will cooperate with the two guide rods 95 laterally plugged into the lower end of the front side to realize synchronous movement. Therefore, when the glass substrate 5 is transmitted to the upper end of the front side of the conveyor body 3, the positioning bars 94 on both sides that move relatively can push the glass substrate 5 against each other and push the glass substrate 5 to the center position of the conveyor body 3 to ensure the accuracy of the subsequent exposure position of the glass substrate 5, thereby achieving the advantages of auxiliary positioning and centering of the glass substrate 5 and reducing the occurrence of exposure position deviation.

[0038] Secondly, under the one-time transmission of the driving assembly 96, the adjustment frames 93 on both sides can be efficiently moved relative to or oppositely, which greatly improves the production and processing efficiency and reduces the equipment cost expenditure;

[0039] At the same time, after the lateral clamping and positioning of the glass substrate 5 as a whole is completed, the stepper motors 974 provided on the front sides of the upper ends of the positioning bars 94 on both sides can be respectively operated to enable the stepper motors 974 on both sides to realize the rotation of the active rollers 972 connected to the bottom output ends, and the active rollers 972 on both sides rotate in opposite directions. In this way, when the left active roller 972 rotates counterclockwise, the right active roller 972 rotates clockwise. As a result, the anti-skid belts 971 connected to the outside of the active rollers 972 on both sides will move in the same direction as the corresponding active rollers 972, and cooperate with the driven rollers 973 connected to the rear side to achieve the stability of the forward or backward transmission state. Driven by the rotation of the anti-skid belts 971 on both sides, the glass substrate 5 clamped between the upper ends of the positioning bars 94 on both sides can be moved backward to the accurate center position, thereby reducing the occurrence of inaccurate front and rear exposure positions, and further improving the placement accuracy of the glass substrate 5.

[0040] If the positioning spacing needs to be adjusted later, the servo motor 935 provided on the outer side of the connecting frame 931 can be operated to enable the servo motor 935 to drive the screw 933 connected to the output end. When the screw 933 rotates, the movable plate 934 threadedly connected to the outer side of the screw 933 can realize transverse movement along the rectangular plate at the upper end of the connecting frame 931, that is, the movable plates 934 on both sides will synchronously drive the positioning bars 94 provided on the upper end to move transversely in opposite directions to realize the expansion of the spacing between the positioning bars 94 on both sides. In this way, as the positioning spacing between the positioning bars 94 on both sides expands, the positioning and centering requirements of larger-sized glass substrates 5 can be met, thereby achieving the advantage of flexible adjustment and expansion of the positioning spacing to meet the positioning requirements of larger-sized glass substrates 5.

[0041] The utility model provides a fully automatic production equipment device for a touch screen exposure process, by setting an auxiliary positioning device 9, that is, an adjustment frame 93 arranged on the left and right sides of a shell 91, which cooperates with a screw rod 933 and a servo motor 935 to realize the lateral adjustment of a movable plate 934, so that the positioning bars 94 at the upper ends of the movable plates 934 arranged on both sides can realize flexible adjustment of the spacing between them, thereby achieving the advantage of flexible adjustment and expansion of the positioning spacing to meet the positioning requirements of a larger size glass substrate 5, and a driving component 96 and a positioning reinforcement component 97 are set, that is, under the reciprocating push and pull of a rotating plate 962 and a connecting rod 963, the racks 932 on both sides can be meshed with the gear 92 for transmission, so that the positioning bars 94 set on both sides can quickly clamp and position the glass substrate 5, and the anti-slip belts 971 arranged on both sides can be guided forward and backward to assist in the flexible adjustment of the front and rear positions, thereby achieving the advantages of efficient centering positioning of the glass substrate 5 and reducing the occurrence of exposure position offset.
