Description

Technical Field

[0001] The present application relates to the technical field of handling equipment, and in particular to a suction cup device, a suction cup frame and glass production equipment. Background Art

[0002] At present, most of the production lines for cover glass adopt float process. There are two types of stacking of finished glass at the cold end: vertical stacking and flat stacking. Whether it is vertical stacking or flat stacking, the suction cup is indispensable for grabbing the glass on the conveyor roller. There are two types of suction cups in the industry: flat suction cups and accordion suction cups. When these two types of suction cups are used to produce glass thicker than 0.33mm, the glass will bend less after the suction cups suck the glass, and they can be used normally. The thicker the glass, the smaller the deformation.

[0003] However, when producing ultra-thin glass such as 0.25mm and 0.33mm, if the commonly used flat suction cup or accordion suction cup is used, the following problems will occur:

[0004] Since the roller spacing of the production line is 150mm to 160mm, the flat suction cup needs the pressure of the spring to hold the glass. The spring on the suction cup column will bend and deform the glass, causing the suction cup to leak and the vacuum to be insufficient, resulting in glass falling and failure of grabbing and transferring. When the stress of the glass fluctuates, it will directly crush the glass on the conveyor roller. The accordion suction cup is a heavy-duty suction cup with greater suction force than the flat suction cup. This type of suction cup directly uses strong suction force to deform and bend the glass inside the suction cup until the glass explodes. Utility Model Content

[0005] A technical problem to be solved by the present application is that when producing ultra-thin glass, when using existing flat suction cups or accordion suction cups, it is easy for the suction force to be too small to cause the glass to fall off, or the suction force to be too large to cause the glass to crack.

[0006] In order to solve the above technical problems, the embodiment of the present application provides a suction cup device, including: a vacuum suction cup, a rubber diaphragm, a suction cup seat and a vacuum regulator;

[0014] One end of the spring is arranged in the through hole of the core shaft and abuts against the step, and the other end is arranged in the through hole of the adjusting knob and abuts against the sealing steel ball, so that the air inlet of the adjusting knob is blocked by the sealing steel ball;

[0015] A filter is provided outside the air inlet of the adjustment knob;

[0038] Reference Manual Attached Figure 1 , showing a schematic structural diagram of a suction cup device disclosed in an embodiment of the present application.

[0039] An embodiment of the present application provides a suction cup device, comprising: a vacuum suction cup 1, a rubber diaphragm 2, a suction cup seat 3 and a vacuum regulator 4.

[0040] One end of the suction cup seat 3 is connected to the suction cup column, and the other end is connected to the vacuum suction cup 1.

[0041] The vacuum regulator 4 is disposed in the first mounting hole 5 of the suction cup seat 3 .

[0042] It should be noted that the function of the vacuum regulator 4 is to adjust the vacuum degree in the suction cup cavity of the vacuum suction cup 1, so as to select the appropriate suction force according to the actual situation, reduce the squeezing of the glass during grasping, and avoid the glass falling due to too little suction or the glass cracking due to too much suction.

[0043] The rubber diaphragm 2 is arranged in the suction cup cavity of the vacuum suction cup 1 .

[0044] It should be noted that the function of the rubber partition 2 is to ensure the elasticity of the suction cup itself and to forcibly limit the deformation of the ultra-thin glass in the suction cup cavity after being sucked, without affecting the suction force, so as to prevent the glass from being sucked and bursting.

[0045] In the utility model, the vacuum degree in the suction cup cavity of the vacuum suction cup can be adjusted by a vacuum regulator, so that the appropriate suction force can be selected according to the actual situation, and the squeezing of the glass can be reduced when grabbing, so as to avoid the glass falling due to too small suction force or the glass bursting due to too large suction force. At the same time, a rubber partition is arranged in the suction cup cavity of the vacuum suction cup to reduce the deformation and bending of the glass inside the suction cup without weakening the suction force, so as to further avoid the glass bursting.

[0046] In some embodiments, the vacuum regulator 4 includes: a core shaft 41 , an adjusting knob 42 , a sealing ring 43 , a spring 44 , a sealing steel ball 45 and a filter 46 .

[0047] One end of the core shaft 41 is threadedly connected to the first mounting hole 5 of the suction cup seat 3, and the other end is threadedly connected to the mounting hole of the adjusting knob.

[0048] Optionally, the outer surface of the adjusting knob 42 is processed into a knurled shape to increase the manual friction force. The vacuum degree in the vacuum chuck 1 can be fine-tuned by turning the adjusting knob 42 .

[0049] A sealing ring 43 is provided between the outer surface of the core shaft 41 and the inner wall surface of the mounting hole of the adjusting knob 42 .

[0050] It should be noted that the sealing ring 43 is used for active vacuum sealing when the adjusting knob 42 is turned, and the adjusting knob 42 is self-locked after adjustment by friction.

[0051] The core shaft 41 is provided with a through hole having a step.

[0052] One end of the spring 44 is disposed in the through hole of the core shaft and abuts against the step, and the other end is disposed in the through hole of the adjusting knob 42 and abuts against the sealing steel ball 45 , thereby sealing the air inlet of the adjusting knob 42 .

[0053] A filter 46 is disposed outside the air inlet of the adjusting knob 42 .

[0054] It should be noted that the filter 46 is used to filter air impurities when air is inhaled.

[0055] By rotating the adjusting knob 42, the vacuum degree in the suction cup cavity of the vacuum suction cup 1 is adjusted, thereby controlling the suction force and the deformation amount of the glass after being sucked.

[0056] The working principle of the vacuum regulator 4 is described below:

[0057] When the adjustment knob 42 is rotated counterclockwise, the elastic force of the spring 44 decreases, and the spring thrust of the sealing steel ball 45 also decreases. When the outward thrust of the spring 44 received by the sealing steel ball 45 is less than the atmospheric pressure suction force received by the sealing steel ball 45, the air will push the sealing steel ball 45 into the vacuum suction cup 1, reduce the vacuum degree inside the vacuum suction cup 1, and reduce the vacuum suction force on the glass. Conversely, when the adjustment knob 42 is rotated clockwise, the outward thrust of the spring 44 pushing the sealing steel ball 45 gradually increases, which can reduce the outside air from entering the vacuum suction cup 1, increase the vacuum degree inside the vacuum suction cup 1, and increase the vacuum suction force on the glass.

[0058] Furthermore, when used for the first time, the adjusting knob 42 should be tightened clockwise to keep the spring 44 compressed sufficiently, so as to push the sealing steel ball 45 to be strictly sealed with the air inlet hole in the center of the adjusting knob 42 and maintain the original vacuum degree of the vacuum system.

[0059] In the utility model, a flexible and reliable way is provided to control the suction force of the suction cup, so that it is suitable for glass of different types and thicknesses, and can effectively improve production efficiency and product quality.

[0060] In some embodiments, a gap is left between the rubber diaphragm 2 and the inner wall surface of the vacuum suction cup 1 .

[0061] It should be noted that a gap is left between the rubber diaphragm 2 and the inner wall surface of the vacuum suction cup 1 to ensure that the rubber diaphragm 2 does not affect the elastic force of the vacuum suction cup 1 .

[0062] In the present invention, by leaving a gap, it can be ensured that the rubber diaphragm 2 does not affect the elasticity of the vacuum suction cup 1. In this way, the original elasticity and adsorption performance of the vacuum suction cup 1 can be maintained, ensuring that the vacuum suction cup 1 can effectively adhere to the glass surface.

[0063] In some embodiments, the rubber diaphragm 2 is provided with through holes.

[0064] It should be noted that the rubber diaphragm 2 is provided with a through hole to ensure the penetration of the internal cavity of the vacuum suction cup 1 .

[0065] In some embodiments, the rubber diaphragm includes a first rubber diaphragm 21 and a second rubber diaphragm 22. The first rubber diaphragm 21 and the second rubber diaphragm 22 are stacked and arranged in the suction cup cavity of the vacuum suction cup 1.

[0066] Optionally, the first rubber diaphragm 21 and the second rubber diaphragm 22 have different sizes, and the sizes of the first rubber diaphragm 21 and the second rubber diaphragm 22 can be set according to the conditions of the suction cup cavity.

[0067] In the present invention, two rubber partitions 2, one large and one small, are designed to facilitate installation and adapt to the internal structure of the suction cup cavity, thereby reducing the manufacturing cost of the suction cup.

[0068] In some embodiments, the suction cup device further comprises: a vacuum gauge; the vacuum gauge is disposed in the second mounting hole 6 of the suction cup seat 3, and the vacuum gauge is used to monitor the pressure in the vacuum suction cup 1. The vacuum gauge can provide a reference for adjusting the vacuum degree.

[0069] In some embodiments, the vacuum regulator 4 includes: one end of the suction cup seat 3 is connected to the suction cup column through a third mounting hole, and a sealing gasket 7 is arranged between one end of the suction cup seat 3 and the suction cup column.

[0070] Optionally, a screw is provided in the third mounting hole 8 to connect one end of the suction cup seat 3 to the suction cup column.

[0071] In some embodiments, the other end of the suction cup seat 3 is connected to the vacuum suction cup 1 through a screw 9.

[0072] By adopting the suction cup device provided by the utility model, the glass will no longer fail to be sucked or cracked during the production process, which completely solves the technical problem of grabbing and stacking in the production process of ultra-thin cover glass below 0.33 mm and improves the yield rate by more than 10%.

[0073] An embodiment of the present application provides a suction cup rack, comprising a plurality of the above-mentioned suction cup devices, each of which independently adjusts the vacuum degree in the suction cup cavity of the vacuum suction cup.

[0074] Optionally, the suction cup frame includes at least eight suction cup devices, each of which can adjust its vacuum degree according to the deformation of the glass after being sucked. When the glass is severely deformed, adjusting the vacuum regulator knob counterclockwise can suck outside air into the suction cup cavity to reduce the suction force, and vice versa, adjusting the vacuum regulator knob clockwise can reduce the outside air entering the suction cup cavity and increase the suction force of the suction cup until it is closed.

[0075] An embodiment of the present application provides a glass production equipment, including the above-mentioned suction cup device, or the above-mentioned suction cup frame.

[0076] Through the above technical scheme, the suction cup device, suction cup rack and glass production equipment provided by the present application can adjust the vacuum degree in the suction cup cavity of the vacuum suction cup through the vacuum regulator, so as to facilitate the selection of appropriate suction force according to actual conditions, reduce the squeezing of the glass during grasping, avoid the glass falling due to too little suction or the glass cracking due to too much suction, and at the same time, a rubber partition is arranged in the suction cup cavity of the vacuum suction cup to reduce the deformation and bending of the glass inside the suction cup without weakening the suction force, thereby further avoiding the glass cracking.
