Description

Technical Field

[0001] This disclosure relates to the field of glass processing technology, and in particular to a transfer device and a glass production line for a glass production line. Background Technology

[0002] In the glass production process, including cutting, grinding and polishing, a series of steps are involved. After completing the previous step, the glass needs to be picked up from the previous step's workstation and transferred to the next step's workstation by a transfer device.

[0003] The prior art proposes a glass transfer suction cup mounting structure and its suction cup machine (CN 108946168 A). It includes a square suction cup mounting plate with a square upright rod vertically mounted on its upper part. The suction cup mounting plate has slide rails evenly spaced along its diagonals, centered on the square upright rod. Dovetail-shaped sliders are slidably connected within each slide rail. An adjustment component is fixedly connected between the sliders and the square upright rod. A suction cup assembly is mounted on top of the sliders. A dustproof component covering the vacuum suction cup is snapped into the bottom of the suction cup mounting plate. Adjustment is performed by adjusting the engagement depth between the sleeve rod and the sleeve, using the scale lines on the suction cup mounting plate as a reference, and employing the locking bolts in the adjustment component. This allows the slider to move appropriately within the slide rails. After adjustment, the locking bolts are tightened.

[0004] While the existing technology achieves glass transfer, for larger pieces of glass, multiple suction cups need to be installed on the adsorption plate to ensure safety. These suction cups should be evenly distributed to ensure the glass is firmly adhered to the plate and that all parts of the glass experience balanced adsorption force, preventing damage due to uneven adsorption. However, due to the unevenness of the glass surface during processing, some suction cups may not fully adhere to the glass, necessitating a further reduction in the distance between the adsorption plate and the glass to ensure all suction cups are fully in contact. This inevitably leads to excessive pressure from the suction cups that initially contact the glass, potentially causing damage. Therefore, how to ensure all suction cups fully adhere to the glass and exert adsorption force to firmly attach it to the adsorption plate while preventing damage is a problem that those skilled in the art need to consider, especially when dealing with uneven glass surfaces. Utility Model Content

[0005] One of the technical problems this disclosure aims to solve is how to ensure that all suction cups can fully contact the glass and exert an adhesive force on the glass when the glass surface is uneven, so as to firmly adsorb the glass onto the suction plate, while avoiding damage to the glass.

[0006] To address the aforementioned technical problems, this disclosure provides a transfer device for a glass production line, comprising: a moving mechanism; an adsorption plate connected to the moving end of the moving mechanism; an adsorption assembly for adsorbing glass, comprising a suction cup, a base, and an elastomer, wherein the suction cup is mounted on the base, one end of the elastomer is connected to the base, and the other end is connected to the adsorption plate, and multiple adsorption assemblies are evenly distributed on the adsorption plate; an air extraction mechanism comprising an air extractor and an air extraction pipe, wherein the air extractor is connected to the suction cup through the air extraction pipe to extract air from the suction cup, thereby causing a change in the air pressure inside the suction cup; and an air pressure sensor installed inside the suction cup to monitor changes in the air pressure inside the suction cup.

[0007] In some embodiments, the elastomer includes a spring.

[0008] In some embodiments, a first connecting plate is connected to one end of the spring, and the first connecting plate is connected to the base by a first bolt.

[0009] In some embodiments, a second connecting plate is connected to the other end of the spring, and the second connecting plate is connected to the adsorption plate by a second bolt.

[0010] In some embodiments, the suction tube is retractable.

[0011] In some embodiments, the moving mechanism includes a robotic arm, with an adsorption plate attached to the moving end of the robotic arm.

[0012] In some embodiments, the elastomer further includes a rubber rod, one end of which is connected to the base and the other end to the adsorption plate, with a spring sleeved on the rubber rod.

[0013] In some embodiments, the transfer device further includes an alarm, which is mounted on the base and connected to a pressure sensor.

[0014] In addition, this disclosure also provides a glass production line, including the aforementioned glass production line transfer device.

[0015] In some embodiments, the transfer device includes multiple transfer devices distributed along the process flow direction of the glass production line.

[0016] According to the above technical solution, this disclosure provides a transfer device and a glass production line for a glass production line. The transfer device connects the adsorption plate and the suction cups through an elastomer, enabling all suction cups to simultaneously abut against the glass. The negative pressure formed within the suction cups firmly adsorbs the glass onto the adsorption plate. Simultaneously, the buffering effect of the elastomer prevents some suction cups from exerting excessive pressure on the glass, thus avoiding damage. A pressure sensor further ensures the safety of the glass. The first connecting plate, first bolt, second connecting plate, and second bolt facilitate the assembly and disassembly of the suction cups and the elastomer. The spring and rubber rod form an elastomer, which, while being elastic and deformable, also possesses a certain degree of rigidity, thereby ensuring the safety of the glass.

[0029] As mentioned in the background section, while existing technologies have enabled glass transfer, when transferring large-sized glass pieces, multiple suction cups need to be installed on the adsorption plate to ensure glass safety. These suction cups are evenly distributed on the adsorption plate to ensure the glass is firmly adhered to it, and to ensure that all parts of the glass receive a balanced adsorption force, preventing damage due to uneven adsorption. However, because the surface of glass can be uneven during processing, some suction cups may fully contact the glass while others fail to do so. This necessitates further reducing the distance between the adsorption plate and the glass to ensure all suction cups are fully in contact. This inevitably leads to the suction cups that initially contact the glass exerting significant pressure on the contact area, potentially causing damage. Based on this, the inventors of this application provide a transfer device and a glass production line in one or more embodiments. The transfer device connects the suction plate and the suction cups via an elastomer, enabling all suction cups to simultaneously abut against the glass. The negative pressure formed within the suction cups firmly adheres the glass to the suction plate. Simultaneously, the buffering effect of the elastomer prevents some suction cups from exerting excessive pressure on the glass, thus avoiding damage. It is believed that this solution addresses one or more problems in the prior art.

[0030] To address the aforementioned technical problems, this utility model provides a transfer device for a glass production line, such as... Figure 1 As shown, it includes: a moving mechanism 1; an adsorption plate 2 connected to the moving end of the moving mechanism 1; an adsorption assembly for adsorbing glass 12, including a suction cup 3, a base 4, and an elastomer 5, the suction cup 3 being mounted on the base 4, one end of the elastomer 5 being connected to the base 4, and the other end being connected to the adsorption plate 2, the adsorption assembly including multiple components evenly distributed on the adsorption plate 2; an air extraction mechanism including an air extractor and an air extraction pipe 6, the air extractor being connected to the suction cup 3 through the air extraction pipe 6 to extract air from the suction cup 3, thereby causing a change in the air pressure inside the suction cup 3; and an air pressure sensor installed inside the suction cup 3 to monitor changes in the air pressure inside the suction cup 3.

[0031] Specifically, after the glass 12 completes the previous process, the moving mechanism 1 moves the adsorption plate 2 above the glass 12, making the adsorption plate 2 parallel to the glass 12. The moving mechanism 1 then moves the adsorption plate 2 downwards. Because the surface of the glass 12 is uneven, as the adsorption plate 2 moves downwards, some of the suction cups 3 first come into complete contact with the glass 12. The moving mechanism 1 continues to move the adsorption plate 2 downwards until all the suction cups 3 are completely in contact with the glass 12. Then, the suction mechanism is activated to evacuate the suction cups 3, creating a negative pressure inside them, thereby adsorbing the glass 12 onto the suction cups 3. Since the adsorption plate 2 and the suction cups 3 are connected by an elastic body 5, after some of the suction cups 3 come into contact with the glass 12, as the adsorption plate 2 continues to move downwards, the deformation of the elastic body 5 helps to reduce the increased pressure on the glass 12 at the contact point, thus preventing damage to the glass 12 due to increased pressure. After the suction mechanism completes the evacuation of the suction cups 3, the air pressure sensor installed in each suction cup 3 detects the air pressure value and sends it to the controller of the transfer device. When the air pressure values ​​in all suction cups 3 meet the design value for negative pressure, the controller instructs the moving mechanism 1 to transfer the glass 12 to the next process station. The air pressure sensor further ensures the safety of the glass 12 during the transfer process, avoiding the problem of the glass 12 falling off the suction plate 2 and being damaged due to insufficient negative pressure or insufficient negative pressure in some suction cups 3.

[0032] Compared with the prior art, the glass production line transfer device of this application connects the adsorption plate 2 and the suction cup 3 through the elastomer 5, so that all the suction cups 3 can simultaneously abut against the glass 12, and the negative pressure formed in the suction cup 3 can firmly adsorb the glass 12 onto the adsorption plate 2. At the same time, the buffering effect of the elastomer 5 avoids the problem of some suction cups 3 exerting too much pressure on the glass 12 and causing damage to the glass 12; and the air pressure sensor further ensures the safety of the glass 12.

[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, the elastic body 5 includes a spring 7. The elastic deformation of the elastic body 5 is achieved by the spring 7. Specifically, the dimensions and elastic modulus of the spring 7 can be obtained through experiments.

[0034] In some embodiments, such as Figure 2 As shown, a first connecting plate 8 is connected to one end of the spring 7, and the first connecting plate 8 is connected to the base 4 by a first bolt 9. The first connecting plate 8 and the first bolt 9 enable a detachable connection between the spring 7 and the suction cup 3, which facilitates the replacement of the suction cup 3 and the spring 7 when the suction cup 3 malfunctions or the spring 7 is damaged or fails.

[0035] In some embodiments, such as Figure 1As shown, a second connecting plate 10 is connected to the other end of the spring 7, and the second connecting plate 10 is connected to the adsorption plate 2 by a second bolt 11. The second connecting plate 10 and the second bolt 11 enable a detachable connection between the spring 7 and the adsorption plate 2, making it easy to remove and replace the damaged spring 7 from the adsorption plate 2 when it fails.

[0036] In some embodiments, the suction pipe 6 is retractable. Specifically, the vacuum pump can be placed on the ground, and during the movement of the moving mechanism 1, the extension and retraction of the suction pipe 6 can coordinate with the movement of the suction cup 3.

[0037] In some embodiments, the moving mechanism 1 includes a robotic arm, and an adsorption plate 2 is connected to the moving end of the robotic arm. The robotic arm enables the moving function of the moving mechanism 1.

[0038] In some embodiments, the elastomer 5 further includes a rubber rod (not shown in the figure), one end of which is connected to the base 4 and the other end to the adsorption plate 2, and a spring 7 is sleeved on the rubber rod. The spring 7 and the rubber rod together form the elastomer 5, which makes the elastomer 5 elastically deformable while also having a certain rigidity, thereby ensuring the safety of the glass 12.

[0039] In some embodiments, the transfer device further includes an alarm (not shown in the figure), which is mounted on the base 4 and connected to a pressure sensor. When the vacuum pump finishes pumping air and the pressure sensor detects that the negative pressure value has not reached the design value, the alarm sounds. When the number of alarms that sound exceed a set ratio, the transfer device is set to fail to grasp the glass 12 and needs to be grasped again.

[0040] In addition, this utility model also provides a glass production line, including the aforementioned glass production line transfer device.

[0041] In some embodiments, the transfer device includes multiple devices distributed along the process flow direction of the glass production line. By setting up multiple transfer devices, continuous flow operation of the glass production line along its process flow direction is achieved, thereby improving the production efficiency of the glass production line.

[0042] In summary, compared with the prior art, this disclosure provides a transfer device and a glass production line for a glass production line. The transfer device connects the adsorption plate 2 and the suction cups 3 via an elastomer 5, enabling all suction cups 3 to simultaneously abut against the glass 12. The negative pressure formed within the suction cups 3 firmly adsorbs the glass 12 onto the adsorption plate 2. Simultaneously, the buffering effect of the elastomer 5 prevents some suction cups 3 from exerting excessive pressure on the glass 12, thus avoiding damage to the glass 12. A pressure sensor further ensures the safety of the glass 12. The first connecting plate 8, the first bolt 9, the second connecting plate 10, and the second bolt 11 facilitate the assembly and disassembly of the suction cups 3 and the elastomer 5. The spring 7 and the rubber rod form the elastomer 5, which is elastic and deformable while also possessing a certain degree of rigidity, thereby ensuring the safety of the glass 12.
