Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing production lines, in particular to a transmission device for a glue dispensing production line for an ultra-large-size touch screen. Background Art

[0002] In the manufacturing process of super-large touch screens (usually over 75 inches, and also 98 inches and 110 inches), there is a process in which, after the TP conductive film is attached to the glass cover plate, glue needs to be dispensed around the periphery of the TP conductive film. The conventional dispensing method is to place the glass cover plate flat on a vertical carrier and then transfer it to a dispensing device for dispensing. Due to the large size of the glass cover plate, the dispensing device and its conveyor belt (or conveying channel) occupy a large area. Moreover, such a dispensing method is extremely inefficient. In addition, before dispensing, the glass cover plate with the TP conductive film needs to be moved onto the vertical carrier on the conveyor belt, and the vertical carrier transfers the glass cover plate to the dispensing device for dispensing. After the dispensing is completed, the glass cover plate needs to be removed from the vertical carrier and transferred to the next assembly process. Such a process of moving up and down is troublesome, time-consuming and labor-intensive. Therefore, it is necessary to study a new solution. Summary of the invention

[0003] In view of this, the present invention aims at the defects of the prior art, and its main purpose is to provide a transmission device for an ultra-large touch screen dispensing production line, which is used to solve the above-mentioned problems.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: A transmission device for a dispensing production line of an extra-large touch screen includes a vertical carrier, two planar tracks arranged opposite to each other, and a transfer device for driving the vertical carrier to move on the two planar tracks, wherein a slide rail is arranged on the outer side wall of each planar track; The vertical carrier includes a load-bearing base frame and a side leaning frame. The bottom of the load-bearing base frame is provided with a first caster that can move on the ground and a second caster that can move on the two aforementioned planar rails. Slide blocks are provided on both sides of the load-bearing base frame, and the two slide blocks respectively correspond to the two aforementioned slide rails. In addition, a lower fixing structure for fixing the bottom of the glass cover plate is provided on the load-bearing base frame, and the side leaning frame is vertically arranged at one side edge of the load-bearing base frame. The top of the side leaning frame is provided with an upper fixing structure for fixing the top of the glass cover plate.

[0005] As a preferred solution, the transfer device includes a conveyor belt body and a motor driving the conveyor belt body to move along a conveying direction, and the conveyor belt body is provided with a plurality of through holes of preset length and preset width at intervals.

[0006] As a preferred solution, a strip-shaped driving portion is protruded between two adjacent through holes on the conveyor belt body, and correspondingly, a strip-shaped follower portion is protruded from the bottom of the supporting frame. When working, the strip-shaped driving portion rests on the strip-shaped follower portion and pushes the strip-shaped follower portion to move.

[0007] As a preferred solution, the lower fixing structure includes a pressing strip for pressing the bottom of the glass cover plate and a screw for controlling the pressing strip to move closer to / away from the side support frame, and the pressing strip is arranged opposite to the side support frame.

[0008] As a preferred solution, the upper fixing structure includes two groups of clamping assemblies, each group of clamping assemblies is respectively arranged at the two ends of the top of the side leaning frame, each clamping assembly includes a clamping arm, a clamping member, and a screw bolt, the first end of the clamping arm is rotatably connected to the side leaning frame, the screw bolt is screwed into the second end of the clamping arm and extends toward the glass cover plate, and the clamping member is connected to the screw bolt and faces the side leaning frame.

[0009] As a preferred solution, the first caster is a universal wheel, the second caster is a unidirectional wheel, and the rolling direction of the second caster is consistent with the conveying direction.

[0010] As a preferred embodiment, the side support frame includes a first plate frame, which is used to support the glass cover plate. The first plate frame includes three transverse rods arranged at intervals up and down and two connecting rods arranged at intervals left and right, and the two connecting rods are away from the ends of the transverse rods so that a space is formed between the ends of the three transverse rods.

[0011] As a preferred solution, the side frame also includes a second frame, which is located at the edge of the supporting base frame. The first frame and the second frame are arranged at a preset distance and are located on the inner side of the second frame, and a storage space is formed between the first frame and the second frame.

[0012] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that the main advantages are: By designing a vertical carrier, in practice, the glass cover plate can be placed vertically on the vertical carrier so that the dispensing device can dispense glue on multiple glass cover plates. It should be noted that when in use, multiple partition plates are required. The partition plates can effectively separate different glass cover plates to avoid the glass cover plates being too close. Support parts are convexly provided at the four corners of each partition plate. Along the circumference of the partition plate, a movable space for the needle tube of the dispensing head to enter and exit is formed between two adjacent support parts. This vertical carrier combined with the corresponding dispensing method can reduce the floor space occupied; In one step, the vertical carrier has a first caster wheel, which can move freely on the ground. The vertical carrier has a second caster wheel, which can move on the plane track and bear most of the pressure of the vertical carrier. Furthermore, by cooperating with the slider and the slide rail between the vertical carrier and the plane track, the vertical carrier can be accurately limited to ensure accurate glue dispensing. With this structure, after the glue dispensing is completed, the vertical carrier can be directly pulled to other processes. The whole process reduces the action of removing the glass cover once, which is very convenient and saves time and effort.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0018] See also Figures 1 to 7 The embodiment of the present invention provides a transmission device for a dispensing production line of an ultra-large touch screen, comprising a vertical carrier 10, two planar rails 20 arranged opposite to each other, and a transfer device 30 for driving the vertical carrier 10 to move on the two planar rails 20, and a slide rail 21 is provided on the outer wall of each planar rail 20; the vertical carrier 10 comprises a bearing frame 11 and a side frame 12, the bottom of the bearing frame 11 is provided with a first caster 13 movable on the ground and a second caster 14 movable on the two planar rails 20, both sides of the bearing frame 11 are provided with sliders 15, and the two sliders 15 are respectively matched with the two slide rails 21, and the bearing frame 11 is provided with a lower fixing structure 40 for fixing the bottom of the glass cover plate, the side frame 12 is vertically arranged at one side of the bearing frame 11, and the top of the side frame 12 is provided with an upper fixing structure 50 for fixing the top of the glass cover plate.

[0019] By designing a vertical carrier 10, in practice, the glass cover plate can be placed vertically on the vertical carrier 10 so that the glue dispensing device can dispense glue on multiple glass cover plates. It should be noted that when in use, multiple partition plates 70 are required. The partition plates 70 can effectively separate different glass cover plates to avoid the glass cover plates being too close. Support parts are convexly provided at the four corners of each partition plate 70. Along the circumference of the partition plate 70, an activity space 71 for the needle tube of the glue dispensing head to enter and exit is formed between two adjacent support parts. This vertical carrier 10 can reduce the floor space when combined with the corresponding glue dispensing method; further, the The vertical carrier 10 has a first caster 13 that can move freely on the ground. The vertical carrier 10 has a second caster 14 that can move on the plane track 20 and bear most of the pressure of the vertical carrier 10. Furthermore, by cooperating with the slider 15 and the slide rail 21 between the vertical carrier 10 and the plane track 20, the vertical carrier 10 can be accurately limited to ensure accurate glue dispensing. With such a structure, after the glue dispensing is completed, the vertical carrier 10 can be directly pulled to other processes. The whole process reduces the action of removing the glass cover once, which is very convenient and saves time and effort.

[0020] In addition, the dispensing device includes four groups of dispensing mechanisms 60, which are arranged in the up, down, left, and right directions corresponding to the four sides of the TP conductive film, and the dispensing heads of the four groups of dispensing mechanisms 60 are used to dispense glue on the four sides of the TP conductive film respectively.

[0021] Furthermore, the transfer device 30 includes a conveyor belt 31 and a motor (not shown) for driving the conveyor belt 31 to move along the conveying direction. A plurality of through holes 32 of preset length and preset width are arranged at intervals on the conveyor belt 31. The preset length extends along the conveying direction and is greater than the bottom edge of the glass cover plate, and the preset width is greater than the thickness when multiple glass cover plates are arranged side by side on the supporting chassis 11, so that the glue dispensing needle of the glue dispensing head can extend to the bottom edge of the TP conductive film and complete the glue dispensing, thereby avoiding interference of the conveyor belt 31 on the glue dispensing operation.

[0022] Furthermore, a strip-shaped toggle portion 33 is protruded between two adjacent through holes 32 on the conveyor belt body 31, and correspondingly, a strip-shaped follower portion 16 is protruded from the bottom of the carrying chassis 11. When working, the strip-shaped toggle portion 33 abuts against the strip-shaped follower portion 16 and pushes the strip-shaped follower portion 16 to move. In this way, the vertical carrier 10 can be transferred. This design ensures the stability of the vertical carrier 10 during the transmission process. The contact area between the strip-shaped toggle portion 33 and the strip-shaped follower portion 16 is relatively large, which can provide sufficient thrust to enable the vertical carrier 10 to move smoothly, thereby avoiding shaking or deviation of the vertical carrier 10 during the movement.

[0023] Furthermore, the lower fixing structure 40 includes a pressing bar 41 for pressing the bottom of the glass cover plate and a screw 42 for controlling the pressing bar 41 to move closer to / away from the side frame 12. The pressing bar 41 is arranged opposite to the side frame 12. The combination of the pressing bar 41 and the screw 42 can effectively press the bottom of the glass cover plate. By screwing the screw 42, the pressing bar 41 can be controlled to move closer to or away from the side frame 12, thereby adapting to glass cover plates of different thicknesses. This adjustability enables the transmission device to be applicable to the production of ultra-large touch screens of various specifications, thereby improving the versatility of the device.

[0024] Furthermore, the upper fixing structure 50 includes two groups of clamping assemblies, each group of clamping assemblies is respectively arranged at the two ends of the top of the side leaning frame 12, each clamping assembly includes a clamping arm 51, a clamping member 52, and a screw bolt 53, the first end of the clamping arm 51 is rotatably connected to the side leaning frame 12, the screw bolt 53 is screwed into the second end of the clamping arm 51 and extends toward the glass cover plate, the clamping member 52 is connected to the screw bolt 53 and faces the side leaning frame 12, the two groups of clamping assemblies are respectively arranged at the two ends of the top of the side leaning frame 12, and the top of the glass cover plate can be fixed from two positions to ensure the stability of the glass cover plate on the carrier.

[0025] Furthermore, the first caster 13 is a universal wheel, and the second caster 14 is a unidirectional wheel. The rolling direction of the second caster 14 is consistent with the conveying direction. The flexibility of the universal wheel makes it more convenient for the vertical carrier 10 to transfer the glass cover plate. Whether on the conveyor belt inside the production line or on the ground outside the production line, this carrier can adapt to different movement requirements. The directional rolling of the unidirectional wheel ensures the stable movement of the vertical carrier 10 in the production line.

[0026] Furthermore, the side support frame 12 includes a first plate frame 121, which is used to support the glass cover plate. The first plate frame 121 includes three horizontal rods arranged at intervals up and down and two connecting rods arranged at intervals left and right, and the two connecting rods are away from the ends of the horizontal rods so that a space is formed between the ends of the three horizontal rods. This design allows people to easily grab the edge of the glass cover plate with their hands when carrying the glass cover plate. The existence of the space provides sufficient operating space for the hands, making the carrying easier and more convenient.

[0027] Furthermore, the side frame 12 further includes a second plate frame 122, the second plate frame 122 is located at the edge of the load-bearing base frame 11, the first plate frame 121 and the second plate frame 122 are arranged at a preset distance and are located in the inner direction of the second plate frame 122, and a storage space 123 is formed between the first plate frame 121 and the second plate frame 122. For an oversized glass cover, the vertical carrier 10 is prone to imbalance when carrying. By providing the first plate frame 121 and the second plate frame 122 and arranging them at a preset distance, the balance performance of the carrier can be effectively enhanced. The second plate frame 122 is located at the edge of the load-bearing base frame 11, providing an additional The support reduces the risk of the carrier tilting or overturning. At the same time, the cooperation between the first plate frame 121 and the second plate frame 122 can significantly improve the strength of the side frame 12. The design of the double plate frames can disperse the pressure, increase the overall rigidity and stability of the side frame 12, and ensure that it will not be deformed or damaged during transportation and operation. In addition, the storage space 123 formed between the first plate frame 121 and the second plate frame 122 has multiple uses and can be used to store some small tools, accessories or spare materials related to the glass cover, so that the operator can use them at any time when needed. In addition, the storage space 123 can also play a certain buffering role and reduce the impact of external impact on the glass cover.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
