Description

Technical Field

[0001] The invention relates to the field of anti-glare glass production, and in particular to a feeding device for processing an anti-glare glass display screen. Background Art

[0002] Anti-glare glass is a glass sheet that has been specially processed on both sides or one side to have a lower reflectance than ordinary glass, reducing the light reflectance from 8% to less than 1%, using technology to create a clear and transparent visual effect. The existing method of preparing anti-glare glass can be to spray a layer of optical light-scattering particles on the surface of the glass through a spraying process; or to use atomized coating technology to make it have the effect of absorbing and deflecting the direction of light, so as to achieve the effect of anti-reflection and anti-glare.

[0003] At the same time, the anti-glare glass needs to be transported during the preparation process, and it may be randomly inspected during the transportation process. The method of random inspection is to grab and lift the anti-glare glass on the conveying line through the detection device, and then put the anti-glare glass back on the conveying line after the inspection is completed. The surface of the anti-glare glass is very fragile. At the moment when the anti-glare glass is put back on the conveying line after the detection device is completed, because the conveying line is still in the conveying state, the anti-glare glass is subjected to the vertical grasping force of the detection device and the horizontal conveying force of the conveying line. The conveying line will cause a large friction force on the surface of the anti-glare glass at this moment, thereby wearing the anti-reflection layer of the anti-glare glass. After the spot check of the existing anti-glare glass is completed, the conveying line needs to be stopped and the anti-glare glass is lowered, resulting in a slowdown in production efficiency.

[0004] The purpose of the present invention is to design a feeding device for processing an anti-glare glass display screen in view of the above-mentioned problems in the prior art. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a feeding device for processing an anti-glare glass display screen, which can effectively solve the problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A feeding device for processing an anti-glare glass display screen, comprising:

[0008] An active conveyor belt, the active conveyor belt comprises a plurality of active rotating rollers, and the active rotating roller fixed sleeve is provided with a driving wheel;

[0009] An adsorption device is arranged at the lower side of the active conveyor belt, and the adsorption device comprises a frame, and the frame is provided with a plurality of passive wheels on its upper end surface, and the wheel surface of the passive wheel is provided with a circle of adsorption mechanism, and the adsorption mechanism is connected to a negative pressure source;

[0010] A detection device, arranged on the frame;

[0011] The lifting device includes a plurality of driving cylinders for driving the adsorption device and the detection device to move up and down.

[0012] Furthermore, the passive wheel is a hollow structure, the passive wheel is connected to the negative pressure source, the adsorption mechanism includes a suction cup, the base of the suction cup is connected to the inside of the passive wheel, the disk surface of the suction cup faces the outer periphery of the passive wheel, and the base is made of soft material.

[0013] Furthermore, the passive wheel is axially connected to the frame through a rotating joint, and the rotating joint is connected to the negative pressure source, so that the passive wheel is connected to the negative pressure source, and the passive wheel and the driving wheel have the same direction.

[0014] Furthermore, a sealing tube and a pressure relief tube are provided on the side wall of the base of the adsorption mechanism. When the adsorption mechanism is in a natural state, the sealing tube and the pressure relief tube cooperate to seal the side wall of the base. After the adsorption mechanism is stretched toward the pressure relief tube, the pressure relief tube extends into the sealing tube to break the negative pressure state inside the adsorption mechanism.

[0015] Furthermore, the sealing tube is made of rubber material, the sealing tube connects the inside and outside of the base, the end of the pressure relief tube extending into the sealing tube is a sealing structure, and when the adsorption mechanism is in a natural state, the pressure relief tube is blocked in the sealing tube to isolate the inside and outside of the base.

[0016] Furthermore, the pressure relief pipe is arranged on one side of the sealing tube, the pressure relief pipe passes through the sealing tube, the part of the pressure relief pipe located outside the sealing tube is provided with a first vent, and the side wall of the pressure relief pipe located inside the sealing tube is provided with a second vent, after the adsorption mechanism is stretched toward the pressure relief pipe, the sealing tube moves toward the pressure relief pipe so that the pressure relief pipe further extends into the sealing tube, and the second vent is exposed to the interior of the adsorption mechanism, thereby breaking the negative pressure inside the adsorption mechanism.

[0017] Furthermore, the pressure relief pipe is an L-shaped structure, one end of the pressure relief pipe extends into the sealing pipe, and the other end of the pressure relief pipe is fixedly connected to the passive wheel.

[0018] Furthermore, the detection device includes one or more of a gloss detector, a haze detector, a roughness detector, and a transmittance detector.

[0019] Furthermore, the adsorption device comprises five passive wheels, and the passive wheels are distributed at four corners and a center point of the frame.

[0020] Therefore, the present invention provides the following effects and / or advantages:

[0021] Through the cooperation of the lifting device and the adsorption device, the present application can make the adsorption device protrude from the active conveyor belt, thereby lifting the anti-glare glass that needs to be inspected. During this process, there is no need to stop the operation of the active conveyor belt, which can improve production efficiency.

[0022] In this application, when the anti-glare glass is lowered back to the driving wheel after inspection, the driving wheel is in a rotating state, and the adsorption mechanism is still adsorbed under the anti-glare glass. At this time, a lateral friction force will be generated on the anti-glare glass to drive the anti-glare glass to start lateral transportation, and the anti-glare glass starts to move to the right under the friction of the driving wheel. After that, the anti-glare glass moves to the right and the adsorption mechanism moves to the right under the drive of the anti-glare glass. The passive wheel also rotates clockwise at a certain angle, and the adsorption mechanism is stretched to the right. After the sealing tube moves toward the pressure relief tube so that the pressure relief tube further extends into the sealing tube, the second vent is exposed to the interior of the adsorption mechanism, thereby breaking the negative pressure inside the adsorption mechanism, and the adsorption mechanism in place immediately releases the anti-glare glass. Therefore, in the process of lowering the anti-glare glass back to the conveyor belt, the anti-glare glass can start running immediately after it contacts the driving wheel, and the adsorption mechanism naturally releases the anti-glare glass, and the friction of the driving wheel will not scratch the lower surface of the anti-glare glass.

[0023] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0032] refer to Figure 1 -5. A feeding device for processing an anti-glare glass display screen, comprising:

[0033] An active conveyor belt 1, wherein the active conveyor belt 1 comprises a plurality of active rotating rollers 101, and the active rotating rollers 101 are fixedly sleeved with active wheels 102;

[0034] In this embodiment, the active conveyor belt 1 is a prior art. In addition, the active conveyor belt 1 also includes a rotating motor (not shown), which is used to drive the active rotating roller 101. Figure 1 , the rotating motor drives the transmission roller lowered by the active transmission roller 101, and the transmission roller is connected to the active rotating roller shaft 101 by means of a belt connection. The active rotating roller shafts 101 are arranged in a plurality and in parallel, and each active rotating roller shaft 101 is connected to the transmission roller by a belt to realize the function of a conveyor belt. In addition, the active rotating roller shaft 101 is fixedly sleeved with a driving wheel 102, and the wheel surface of the driving wheel 102 is set to a material such as rubber, which can be used to generate a certain friction on the anti-glare glass and protect the anti-glare glass.

[0035] The adsorption device 2 is arranged on the lower side of the active conveyor belt 1, and the adsorption device 2 includes a frame 201, and the frame 201 is provided with a plurality of passive wheels 202 on its upper end surface, and the wheel surface of the passive wheel 202 is provided with a circle of adsorption mechanism 203, and the adsorption mechanism 203 is connected to a negative pressure source (not shown); further, the adsorption device 2 includes five passive wheels 202, and the passive wheels 202 are distributed at the four corners and the center point of the frame 201.

[0036] In this embodiment, the frame 201 can be a square frame. Since the existing detection method generally detects the four corners of the glass and the center of the glass, a total of five points, the present application is also supported on the five points of the anti-glare glass by the passive wheel 202, so as to facilitate the detection of the detection device. Since the adsorption device 2 is arranged on the lower side of the active conveyor belt 1, and the active conveyor belt 1 is a wheel surface structure, the adsorption device 2 can pass through the active conveyor belt 1 to reach the active conveyor belt 1, and the passive wheel 202 can extend above the active conveyor belt 1, thereby lifting the anti-glare glass, which is convenient for the operator to start various detection devices to detect it. The adsorption mechanism 203 is arranged on the wheel surface of the passive wheel 202, so when the anti-glare glass needs to be lifted, when the anti-glare glass is lifted by the passive wheel 202, the adsorption mechanism 203 can be firmly adsorbed on the bottom surface of the anti-glare glass, thereby preventing the anti-glare glass from shifting and other problems. The negative pressure source is used to generate negative pressure on the adsorption mechanism 203 so that it can be adsorbed.

[0037] A detection device is arranged on the frame; further, the detection device includes one or more of a gloss detector, a haze detector, a roughness detector, and a transmittance detector.

[0038] Among them, gloss testers, haze testers, roughness testers, and transmittance testers are all existing technologies and can be purchased directly.

[0039] The gloss tester consists of an emitter and a receiver. The emitter consists of an incandescent light source and a group of lenses, which produces a certain required incident light beam. The receiver consists of a lens and a photosensitive element, which is used to receive the cone light beam reflected from the sample surface. Gloss is the property of directional selective reflection on the surface of an object, showing different bright spots on the surface or forming an image of an object overlapping the surface. Gloss is the ability of the surface to reflect light when the object is exposed to light.

[0040] The haze detector is used when light enters a certain medium. Due to the uneven structure of the medium, the presence of impurities and bubbles, etc., the light will diffuse and deflect. This part of the light is often called scattered light. Haze is the ratio of the scattered light flux that deviates from the direction of the incident light by more than 2.5 degrees to the transmitted light flux. It is expressed as a percentage. The greater the haze, the lower the gloss and transparency of the film, especially the imaging degree. The concept of haze is understood as the ability to scatter light.

[0041] When the roughness tester measures the surface roughness of a workpiece, the sensor is placed on the surface to be measured. The driving mechanism inside the instrument drives the sensor to slide along the surface to be measured at a constant speed. The sensor senses the roughness of the surface to be measured through the built-in sharp stylus. At this time, the roughness of the surface to be measured causes the stylus to displace, and this displacement causes the inductance of the sensor's inductance coil to change.

[0042] The transmittance tester measures the transmittance as the percentage of the tested luminous flux to the luminous flux incident on the sample.

[0043] The lifting device 3 includes a plurality of driving cylinders for driving the adsorption device 2 and the detection device to move up and down.

[0044] In this embodiment, the lifting device 3 is one or more of a pneumatic cylinder, an oil cylinder, and an electric cylinder. In other embodiments, it can also be any cylinder that can play a driving role, which is not limited here.

[0045] Further, refer to Figure 2 -3, the passive wheel 202 is a hollow structure, the passive wheel 202 is connected to the negative pressure source, the adsorption mechanism 203 includes a suction cup 2031, the base of the suction cup 2031 is connected to the inside of the passive wheel 202, the disk surface of the suction cup 2031 faces the outer periphery of the passive wheel 202, and the base is made of soft material. The passive wheel 202 is axially connected to the frame 201 through a rotating joint 204, and the rotating joint 204 is connected to the negative pressure source, so that the passive wheel 202 is connected to the negative pressure source, and the passive wheel 202 and the driving wheel 102 are in the same direction.

[0046] The rotary joint 204 is a prior art, and realizes the function of the shaft and can also be connected to the passive wheel 202. The corresponding function can be realized by connecting the air pipe to the rotary joint 204.

[0047] The passive wheel 202 and the active wheel 102 have the same orientation, so when the active wheel 102 is conveying the anti-glare glass, the passive wheel 202 can convey the anti-glare glass together with the active wheel 102 at the moment when the passive wheel 202 lifts up the anti-glare glass. The passive wheel 202 continues to lift up the anti-glare glass. Under the action of gravity and the adsorption mechanism 203, the anti-glare glass is tightly grasped by the adsorption mechanism 203 and detached from the upper end surface of the active wheel 102. The shape of the suction cup 2031 is that the end away from the passive wheel 202 is a trumpet-shaped open structure, and the end close to the passive wheel 202 is a circular tubular structure. Under such a structure, the base of the tubular structure of the suction cup 2031 can extend into the hollow part of the passive wheel 202, thereby receiving the negative pressure source, and the open structure of the suction cup 2031 can receive the pressure of the anti-glare glass and adsorb it to provide adsorption force. In addition, the adsorption mechanism 203 is arranged on the wheel surface of the passive wheel 202. During the rotation of the passive wheel 202, the adsorption mechanism 203 at the top of the passive wheel 202 can cooperate with the passive wheel 202 to be adsorbed to the anti-glare glass in turn, providing a structural basis for the simultaneous realization of adsorption grasping and rotation transmission.

[0048] Furthermore, a sealing tube 205 and a pressure relief tube 206 are provided on the side wall of the base of the adsorption mechanism 203. When the adsorption mechanism 203 is in a natural state, the sealing tube 205 and the pressure relief tube 206 cooperate to seal the side wall of the base. After the adsorption mechanism 203 is stretched toward the pressure relief tube 206, the pressure relief tube 206 extends into the sealing tube 205 to break the negative pressure state inside the adsorption mechanism 203.

[0049] Furthermore, the sealing tube 205 is made of rubber material, the sealing tube 205 communicates with the inside and outside of the base, and the adsorption mechanism 203 is in a natural state. The sealing tube 205 is made of rubber material, the sealing tube 205 communicates with the inside and outside of the base, the end of the pressure relief tube 206 extending into the sealing tube 205 is a sealing structure, and the adsorption mechanism 203 is in a natural state, and the pressure relief tube 206 is blocked in the sealing tube 205 to isolate the inside and outside of the base.

[0050] In this embodiment, the natural state of the adsorption mechanism 203 refers to the state when it is not subjected to the external force in the horizontal direction, and at this time, it maintains its inherent shape. Figure 5 The left end of the pressure relief pipe 206 is a sealing structure, which extends into the sealing pipe 205 and does not protrude from the sealing pipe 205, so that the pressure relief pipe 206 can block the sealing pipe 205 in this case. Therefore, the adsorption mechanism 203 can continuously provide negative pressure for adsorbing the corresponding anti-glare glass.

[0051] Furthermore, the pressure relief pipe 206 is arranged on one side of the sealing tube 205, and the pressure relief pipe 206 passes through the sealing tube 205. The part of the pressure relief pipe 206 located on the outside of the sealing tube 205 is provided with a first air vent 2061, and the side wall of the pressure relief pipe 206 located on the inside of the sealing tube 205 is provided with a second air vent 2062. After the adsorption mechanism 203 is stretched toward the pressure relief pipe 206, the sealing tube 206 moves toward the pressure relief pipe 206 so that the pressure relief pipe 206 further extends into the sealing tube 205, and the second air vent 2062 is exposed to the interior of the adsorption mechanism 203, thereby breaking the negative pressure inside the adsorption mechanism 203.

[0052] In this embodiment, the pressure relief pipe 206 is provided with two vents, and the two vents are connected. Therefore, when the pressure relief pipe 206 extends into the sealing pipe 205 and does not protrude from the sealing pipe 205, the second vent 2062 is closed by the sealing pipe 205, and cooperates with the sealing structure of the end of the pressure relief pipe 206 to block the sealing pipe 205, making it unable to ventilate, and thus adsorbed on the lower side of the anti-glare glass. Figure 6When the sealing tube 206 moves toward the pressure relief tube 206 so that the pressure relief tube 206 further extends into the sealing tube 205, the second vent 2062 is exposed to the interior of the adsorption mechanism 203, thereby breaking the negative pressure inside the adsorption mechanism 203. At this time, the adsorption mechanism 203 that breaks the negative pressure loses its adsorption force, thereby detaching from the lower side of the corresponding anti-glare glass.

[0053] Furthermore, the pressure relief pipe 206 is an L-shaped structure, one end of the pressure relief pipe 206 extends into the sealing pipe 205 , and the other end of the pressure relief pipe 206 is fixedly connected to the driven wheel 202 .

[0054] The beneficial effect of this is that when the anti-glare glass is put back to the driving wheel 102 after the inspection, the driving wheel 102 is in a rotating state. Figure 6 At this time, the adsorption mechanism 203 is still adsorbed under the anti-glare glass. At this time, a lateral friction force is generated on the anti-glare glass to drive the anti-glare glass to start lateral transportation. Under the friction force of the active wheel 102, the anti-glare glass starts to move to the right. After that, the anti-glare glass moves to the right and the adsorption mechanism 203 moves to the right under the drive of the anti-glare glass. The passive wheel 202 also rotates clockwise by a certain angle. Figure 7 , the adsorption mechanism 203 is stretched to the right, the sealing tube 206 moves toward the pressure relief tube 206 so that the pressure relief tube 206 further extends into the sealing tube 205, and the second vent 2062 is exposed to the interior of the adsorption mechanism 203, thereby breaking the negative pressure inside the adsorption mechanism 203, and the adsorption mechanism 203 immediately releases the anti-glare glass. Therefore, in the process of lowering the anti-glare glass back to the conveyor belt, the anti-glare glass can start running immediately after contacting the driving wheel 102, and the adsorption mechanism 203 naturally releases the anti-glare glass, and the friction of the driving wheel will not scratch the lower surface of the anti-glare glass.
