Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to an adjustable speed glass substrate conveying device. Background Technology

[0002] Glass substrates are essential components in display equipment. In automated production, conveying devices are typically used to move glass substrates from one workstation to another. The conveying device includes a chamber and multiple conveying rollers disposed within the chamber. The chamber has an inlet and an outlet, and the multiple conveying rollers are arranged at intervals between the inlet and outlet. The rotation of the conveying rollers transports the glass substrate from the inlet to the outlet.

[0003] A search revealed existing technology (publication number: CN219314007U), which describes "a glass substrate conveying device, including an installation platform and a conveying chamber disposed on the installation platform. The lower surface of the installation platform is provided with an air pump and a filter box. The conveying chamber has an inlet and an outlet at both ends. The upper and lower inner walls of the conveying chamber are respectively provided with a first mounting plate and a second mounting plate. Multiple hollow conveying rollers are mounted on the surfaces of the first and second mounting plates via supports. The side walls of the conveying rollers have ventilation holes communicating with the internal cavity. The beneficial effect of this invention is that by having the conveying rollers of the first and second mounting plates contact the two sides of the glass substrate, they contact the surface of the glass substrate during movement. The airflow output from the ventilation holes quickly cleans the surface of the glass substrate. The cleaned dust enters the dust collection plate along with the airflow and is collected by the filter box, thereby effectively ensuring the cleanliness of the glass substrate surface."

[0004] While existing glass substrate conveying devices achieve dust removal during the conveying process, they still have some shortcomings: During conveying, the friction between the conveyor rollers and the glass substrates can lead to wear. Furthermore, during rolling contact with the glass substrates, relative movement between the glass substrates and conveyor rollers may occur at the moment of chain skipping or emergency braking, potentially causing collisions and damage between adjacent glass substrates. Additionally, existing conveyor belt devices are not suitable for rapid glass substrate conveying, resulting in low efficiency. Moreover, the ventilation holes cannot direct dust flow during air blowing, causing dust to spread and create secondary pollution, thus degrading the dust removal effect. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, an adjustable speed glass substrate conveying device is provided to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, an adjustable-speed glass substrate conveying device is provided, comprising: a conveying table, a support on the upper side of the conveying table, a conveyor belt connected to the upper end of the support, and a silicone suction cup and rubber baffle on the surface of the conveyor belt, a drive assembly at one end of the conveyor belt, a lower dust removal assembly at the other end of the conveyor belt, an upper dust removal assembly on the upper side of the conveyor belt, a robotic arm connected to the outer side of the upper dust removal assembly, and a suction cup robotic hand connected to the lower side of the robotic arm.

[0007] Furthermore, the silicone suction cups are arranged in a matrix on the conveyor belt, and the rubber baffles are installed at equal intervals in the gaps between the silicone suction cups.

[0008] Furthermore, the drive assembly includes a frequency converter and a servo motor mounted on the upper side of the conveyor platform, and the servo motor is connected to a drive roller via a synchronous belt and a synchronous pulley, and the drive roller is connected to one end of the conveyor belt.

[0009] Furthermore, the lower dust removal assembly includes a first fixed plate, and a lower dust suction plate is connected to the upper end of the first fixed plate, and a photoelectric sensor is installed on the side of the first fixed plate facing the conveyor belt.

[0010] Furthermore, a first suction pump is connected to the lower side of the lower suction plate via a pipe, and a first dust collection box is connected to the lower side of the first suction pump via a pipe.

[0011] Furthermore, the upper dust removal assembly includes a second fixing plate, and an electric push rod is connected to the upper side of the second fixing plate, and an upper dust suction plate is connected to the lower side of the electric push rod.

[0012] Furthermore, a second suction pump is provided on the upper side of the second fixed plate, and the second suction pump is connected to the upper dust suction plate through a pipe, and a second dust collection box is connected to the outside of the second suction pump through a pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In use, place the glass substrate on the conveyor belt. The weight of the glass substrate presses against the silicone suction cup, thereby squeezing the air inside the silicone suction cup and achieving an adsorption effect with the glass substrate. Then, by starting the servo motor included in the drive assembly, the speed of the servo motor can be adjusted by the frequency converter, which facilitates the adjustment of the movement speed of the conveyor belt. When the glass substrate is stably adsorbed on the conveyor belt, the speed of the servo motor can be increased, which improves the conveying efficiency of the glass substrate and reduces the friction and wear of the glass substrate. In addition, due to the rubber baffle, collision damage between adjacent glass substrates can be prevented when the glass substrate moves relative to the conveyor belt.

[0015] 2. During the glass substrate conveying process, the upper dust removal component is positioned on the upper side of the conveyor belt by moving the robotic arm. Then, the distance between the upper dust suction plate and the upper surface of the glass substrate is adjusted by the electric push rod. This allows the dust on the upper surface of the glass substrate to be sucked up when the first suction pump is turned on. Then, the glass substrate is adsorbed and removed from the conveyor belt by the suction cup robotic arm, so that its lower side is close to the lower dust suction plate included in the lower dust removal component. Then, the second suction pump is turned on to suck up the dust on the lower surface of the glass substrate, thereby achieving a more comprehensive dust removal effect. Attached Figure Description

[0021] Reference Figures 1 to 4 As shown, this utility model provides an adjustable speed glass substrate conveying device, including: a conveying table 1, a support 11 on the upper side of the conveying table 1, and a conveyor belt 2 connected to the upper end of the support 11. The surface of the conveyor belt 2 is provided with silicone suction cups 21 and rubber baffles 22. The silicone suction cups 21 are arranged in a matrix on the conveyor belt 2, and the rubber baffles 22 are equidistantly installed in the gaps between the silicone suction cups 21. One end of the conveyor belt 2 is provided with a drive assembly 7. The drive assembly 7 includes a frequency converter 71 and a servo motor 72 installed on the upper side of the conveying table 1. The servo motor 72 is connected to a drive roller 73 through a synchronous belt and a synchronous pulley. The drive roller 73 is connected to one end of the conveyor belt 2. The other end of the conveyor belt 2 is provided with a lower dust removal assembly 3. The upper side of the conveyor belt 2 is provided with an upper dust removal assembly 6. A robotic arm 4 is connected to the outside of the upper dust removal assembly 6, and a suction cup robotic hand 5 is connected to the lower side of the robotic arm 4.

[0022] In this embodiment, the conveyor table 1, conveyor belt 2, lower dust removal component 3, robotic arm 4, suction cup robotic arm 5, upper dust removal component 6, and drive component 7 constitute the main structure of the adjustable speed glass substrate conveying device involved in this application.

[0023] Among them, the robotic arm 4 and the suction cup robotic hand 5 are commonly used technical devices under existing known technology, and the suction cup robotic hand 5 includes a vacuum pump to achieve a vacuum effect on the suction cup, so that the adsorption force generated after adsorption with the glass substrate is greater than the adsorption force between the glass substrate and the silicone suction cup 21.

[0024] Specifically, the width between the rubber baffles 22 can accommodate various sizes of glass substrates, meaning that the glass substrates are not necessarily arranged at equal intervals, but the rubber baffles 22 are located between adjacent glass substrates.

[0025] Specifically, the frequency converter 71 and the servo motor 72 are electrically connected, and the synchronous pulley connected to the outer end of the drive roller 73 and the synchronous pulley connected to the output shaft end of the servo motor 72 are connected and driven by a synchronous belt.

[0026] like Figure 1 , Figure 3 and Figure 4 In the middle, the lower dust removal assembly 3 includes a first fixed plate 31, and a lower dust suction plate 33 is connected to the upper end of the first fixed plate 31. A photoelectric sensor 32 is installed on the side of the first fixed plate 31 facing the conveyor belt 2. A first suction pump 34 is connected to the lower side of the lower dust suction plate 33 through a pipe, and a first dust collection box 35 is connected to the lower side of the first suction pump 34 through a pipe. The upper dust removal assembly 6 includes a second fixed plate 61, and an electric push rod 62 is connected to the upper side of the second fixed plate 61. An upper dust suction plate 63 is connected to the lower side of the electric push rod 62. A second suction pump 64 is provided on the upper side of the second fixed plate 61. The second suction pump 64 is connected to the upper dust suction plate 63 through a pipe, and a second dust collection box 65 is connected to the outer side of the second suction pump 64 through a pipe.

[0027] Specifically, the lower suction plate 33 and the upper suction plate 63 have the same structure and are both hollow rectangular plates. The rectangular plates have multiple through holes on the side facing the glass substrate, and soft bristles are provided between the through holes. The inner cavity of the rectangular plate generates a negative pressure suction effect through a suction pump. When the soft bristles are in contact with the glass substrate, they can be used to remove dust from its surface.

[0028] In a preferred embodiment, by setting a photoelectric sensor 32, the glass substrate can be detected when it is transported to the end of the conveyor belt 2. Then, the photoelectric sensor 32 is electrically connected to the servo motor 72 through an external controller, and the servo motor 72 is controlled to stop, thereby stopping the movement of the conveyor belt 2.

[0029] During use, the glass substrate is conveyed on the conveyor belt, and its upper side is cleaned by the upper dust suction plate which is adjusted to a certain distance. Then, when it reaches the end of the conveyor belt, it is removed by a robotic arm and a suction cup robotic hand and placed on the upper side of the lower dust suction plate for dust removal on its bottom.

[0030] In use, the glass substrate is placed on the conveyor belt. The weight of the glass substrate presses against the silicone suction cup, squeezing out the air inside the suction cup and achieving an adsorption effect on the glass substrate. Then, by activating the servo motor included in the drive assembly, the speed of the servo motor is adjusted via a frequency converter, which facilitates the adjustment of the conveyor belt's movement speed. When the glass substrate is stably adsorbed on the conveyor belt, the servo motor speed can be increased, improving the conveying efficiency of the glass substrate while reducing friction and wear on the glass substrate. Furthermore, the rubber baffles prevent collision damage between adjacent glass substrates during relative movement between the glass substrate and the conveyor belt.

[0031] The adjustable speed glass substrate conveying device of this invention can effectively solve the problems mentioned in the background technology. Based on the existing adjustable speed glass substrate conveying device technology, it has the advantages of preventing glass substrate friction and wear, collision damage, improving conveying efficiency, and enhancing dust removal effect.
