Description

Technical Field

[0001] The present invention relates to the technical field of insulating glass production and manufacturing, and particularly to a plate pressing method for insulating glass. Background Art

[0002] Currently, the insulating glass plate pressing device and the corresponding working principle are generally as follows: Open the right opening and closing sealing plate of the insulating glass inflating plate press, and convey the first piece of glass of the insulating glass to a specified position inside the insulating glass inflating plate press through the bottom sealing conveying device. The bottom conveying sealing device moves upward, the front moving plate of the insulating glass inflating plate press moves backward, the front moving plate in the insulating glass inflating plate press adsorbs and fixes the first piece of glass through a suction cup, the front moving plate moves forward to reset, and the bottom conveying sealing device moves downward to reset; Then, the second piece of glass and the aluminum frame strip coated with butyl rubber connected to the second piece of glass are conveyed to a position matching the first piece of glass inside the insulating glass inflating plate press through the bottom sealing conveying device. The aluminum frame strip coated with butyl rubber is located between the first piece of glass and the second piece of glass. The bottom sealing conveying device moves upward, closes the right opening and closing sealing plate, and then fills argon gas into the gap between the first piece of glass and the second piece of glass through an inflating device. Stop when the set inflating time or inflating concentration is reached, and then drive the front moving plate to move backward, so that the first piece of glass, the aluminum frame strip coated with butyl rubber, and the second piece of glass are tightly pressed together. Finally, open the left opening and closing sealing plate, the front moving plate is separated from the first piece of glass, and the bottom sealing conveying device moves downward to reset to output the pressed insulating glass.

[0003] In order to ensure the synchronism at different positions when driving the front moving plate to move backward and form a predetermined pressure, ball screws are installed at the four corners of the front moving plate, which are connected in series through a synchronous belt and then connected to a servo motor. The above structure is relatively complex and costly. Summary of the Invention

[0046] In order to solve the problems of complex structure and high cost caused by pressing the first glass sheet and the second glass sheet to form a predetermined pressure in the prior art method for pressing insulating glass, a method for pressing the insulating glass is proposed in this application. This method for pressing the insulating glass can be applied to a gravity pressing device for insulating glass. Figure 2 FIG. is a schematic structural diagram of the gravity pressing device for insulating glass in an embodiment of the present invention. As shown in Figure 2 the figure, the gravity pressing device for insulating glass may include components such as a support mechanism 2, a pressing mechanism 3, a lifting mechanism 4, etc. Of course, the method for pressing the insulating glass in this application can also be applied to other devices, and no limitation is made thereto in this application.

[0047] As shown in Figure 2 the figure, the support mechanism 2 may have a support surface 21 facing upward and used for placing the insulating glass 1. The cross-section of the support surface 21 in the horizontal direction may be larger than that of the insulating glass 1, so as to ensure that all positions of the insulating glass 1 are fully supported. To ensure the uniformity of the force on the insulating glass 1 when the support mechanism 2 and the pressing mechanism 3 press the insulating glass 1, preferably, the support surface 21 may be exactly facing upward. The support mechanism 2 includes a plurality of support feet and a plate pressing platform connecting the upper ends of the support feet. The plate pressing platform may be made of a material with relatively high hardness and strength. Therefore, in order to reduce the possibility of the glass being broken when it touches the plate pressing platform, a first protective layer 9 for protecting the glass is provided on the support surface 21. As feasible, the first protective layer 9 may at least include one of the following, a wooden layer, a plastic layer, a rubber layer and other material layers with relatively low hardness. Further, in order to prevent the glass from directly contacting the first protective layer 9, a layer of felt 11 may be laid above the first protective layer 9, and the insulating glass 1 may be placed on the felt 11.

[0048] The pressing mechanism 3 has a plate pressing surface 31 which is used to press the upper end surface of the insulating glass 1. In one way, the pressing mechanism 3 can be used to load counterweights. The counterweights can be placed above the plate pressing surface 31. There can be one or more counterweights, so that the weights for different requirements can be adjusted. In another way, the pressing mechanism 3 can have a first storage unit 32 which is used to store fluid. By adjusting the amount of the fluid, the weight of the pressing mechanism 3 can be changed, so as to adjust the pressure applied to the insulating glass 1 per unit area. The first storage unit 32 can be formed inside the pressing mechanism 3. For example, the pressing mechanism 3 itself can form a cavity structure which can be used as the first storage unit 32. The first storage unit 32 can also be an independent component placed above the plate pressing surface 31.

[0049] As feasible, the first storage unit 32 can cover most areas of the plate pressing surface 31, so as to ensure that the pressures applied to the upper surface of the insulating glass 1 in various areas of the plate pressing surface 31 are relatively uniform. The first storage unit 32 can be located above the plate pressing surface 31 so that the weight of the first storage unit 32 can be directly applied to the plate pressing surface 31.

[0050] The pressing mechanism 3 can include a plate body having a plate pressing surface 31. Hangers are connected to the four sides of the plate body. On the one hand, the hangers can be used to connect to the lifting mechanism 4. On the other hand, the hangers can enclose the first storage unit 32 or the counterweights to limit them and prevent them from falling out. Further, the plate body can be made of a rigid material, such as high-strength metal, so as to evenly distribute the weight of the first storage unit 32 or the counterweights to the plate pressing surface 31.

[0051] In order to reduce the possibility of the glass being broken when it touches the plate body, a second protective layer 10 for protecting the glass is provided on the lower end surface of the plate pressing surface 31. As feasible, the second protective layer 10 can at least include one of the following: a wooden board layer, a plastic layer, a rubber layer and other material layers with relatively low hardness. In order to avoid the glass directly contacting the second protective layer 10, further, a layer of felt 11 can be laid below the second protective layer 10, and the second protective layer 10 is pressed onto the insulating glass 1 through the felt 11.

[0052] The lifting mechanism 4 is connected to the pressing mechanism 3. Under the action of the lifting mechanism 4, the pressing mechanism 3 can move up and down to press the insulating glass 1 on the supporting surface 21 by gravity. The lifting mechanism 4 and the pressing mechanism 3 can be non-rigidly connected, so as to avoid the lifting mechanism 4 applying an additional downward force on the pressing mechanism 3.

[0053] As feasible, the gravity plate pressing device for insulating glass may include: a supply unit 5. The supply unit 5 can be connected to the first storage unit 32 through a pipeline to convey fluid to the first storage unit 32 and / or recover the fluid in the first storage unit 32, so that the weight of the pressing mechanism 3 can be changed conveniently and quickly at any time.

[0054] As feasible, the supply unit 5 includes a second storage unit 51 for storing fluid; a fluid supply pipe 53 connected to the first storage unit 32 and a pump device 52 connected to the fluid supply pipe 53. Under the action of the pump device 52, the fluid in the second storage unit 51 can be input into the first storage unit 32 through the fluid supply pipe 53.

[0055] As feasible, the supply unit 5 may include: a discharge pipe 54 provided with an opening and closing valve 55. One end of the discharge pipe 54 is connected to the first storage unit 32, and the other end of the discharge pipe 54 is used to discharge the fluid in the first storage unit 32 to the second storage unit 51 or directly discharge the fluid in the first storage unit 32. The opening and closing valve 55 can be an electric opening and closing valve 55, so as to realize remote automatic control.

[0056] The gravity plate pressing device for insulating glass may include: a bracket mechanism 6 having a mounting portion 61 with a preset height. The lifting mechanism 4 is installed at the mounting portion 61 of the bracket mechanism 6. The preset height is higher than the height of the insulating glass 1 placed on the support surface 21. The lifting mechanism 4 is connected to multiple positions of the pressing mechanism 3 through a locking device 7, so that the pressing mechanism 3 can move up and down smoothly. The lifting mechanism 4 can be one, and one lifting mechanism 4 simultaneously controls the connection of multiple locking devices 7 to multiple positions of the pressing mechanism 3. The lifting mechanism 4 can also be multiple, and multiple lifting mechanisms 4 respectively control the connection of multiple locking devices 7 to multiple positions of the pressing mechanism 3. For example, one lifting mechanism 4 controls one locking device 7.

[0057] The lifting mechanism 4 can control the lifting and lowering of the locking device 7. For example, the lifting mechanism 4 may include a motor and a drum, and the motor controls the rotation of the drum so that the locking device 7 is wound around the drum. The locking device 7 can adopt a chain, a rope body, etc. Further, in order to ensure the strength of the rope body, the rope body can be selected as a steel wire rope.

[0058] As feasible, the first storage unit 32 can adopt a flexible bag body, which is convenient for expanding and contracting according to the amount of fluid. The air in the flexible bag body loaded with fluid is discharged as much as possible, so that to a certain extent, the degree of the fluid sloshing back and forth in the first storage unit 32 can be reduced.

[0059] As feasible, a weight measuring unit 8 is connected to the locking device 7, and the weight measuring unit 8 is used to weigh the weight of the pressing mechanism 3. The weight of the pressing mechanism 3 measured by the weight measuring unit 8 can be used to calculate the pressure borne by the insulating glass 1 per unit area, so as to meet the required pressing pressure of the design. If the weight of the pressing mechanism 3 is too small, the pump device 52 can be directly controlled to start, and fluid is input into the first storage unit 32 to increase the weight. If the weight of the pressing mechanism 3 is too large, the on-off valve 55 can be directly controlled to open to discharge part of the fluid in the first storage unit 32.

[0060] A method for pressing plates of an insulating glass proposed in this application, as Figure 1 shown, the method for pressing plates of the insulating glass may include the following steps:

[0061] S101: Place the insulating glass 1 to be plate-pressed on the support surface 21 of the support mechanism 2.

[0062] When it is necessary to press two pieces of glass of the insulating glass 1, the first piece of glass can be placed on the support surface 21 of the support mechanism 2, and then the second piece of glass with a spacer bar can be placed on the first piece of glass. The spacer bar can be coated with a sealant so that both sides of the spacer bar are adhered to and sealed with the first piece of glass and the second piece of glass respectively, thereby forming the insulating glass to be plate-pressed. In other feasible embodiments, the insulating glass to be plate-pressed can also be directly placed on the support surface of the support mechanism. The support surface needs to cover all areas of the first piece of glass, so as to ensure that the support surface can form pressure on all areas of the first piece of glass.

[0063] S102: Press the plate-pressing surface 31 of the pressing mechanism 3 on the insulating glass 1 on the support surface 21 by gravity, and the weight of the pressing mechanism 3 reaches the preset weight.

[0064] In this step, in a feasible embodiment, the weight on the pressing mechanism 3 can be increased to reach the preset weight, and then the pressing mechanism 3 is lowered by the lifting mechanism 4, so that the plate-pressing surface 31 of the pressing mechanism 3 is pressed on the insulating glass 1 on the support surface 21 by gravity.

[0065] For example, when the pressing mechanism 3 is used to load counterweights, increasing the weight on the pressing mechanism 3 to reach the preset weight may specifically include: adding counterweights to the pressing mechanism 3 so that the weight on the pressing mechanism 3 reaches the preset weight; then, the pressing mechanism 3 is lowered by the lifting mechanism 4 so that the plate-pressing surface of the pressing mechanism 3 is pressed on the insulating glass 1 on the support surface 21 by gravity.

[0066] For another example, when the pressing mechanism 3 has a first storage unit 32 for loading fluid, increasing the weight on the pressing mechanism 3 to reach a preset weight may specifically include: inputting fluid into the first storage unit 32 until the weight on the pressing mechanism 3 reaches the preset weight.

[0067] Specifically, the pump device 52 can be turned on, and the fluid in the second storage unit 51 can be input into the first storage unit 32 through the fluid supply pipe, so that the weight on the pressing mechanism 3 reaches the preset weight.

[0068] In some embodiments, the weight measurement unit 8 on the lock 7 can be used to determine that the weight of the pressing mechanism 3 reaches the preset weight. When the weight measurement unit 8 detects that the weight on the pressing mechanism 3 reaches the preset weight, the pump device 52 is controlled to close to stop inputting fluid into the first storage unit 32.

[0069] Through the cooperation of the pump device 52 and the weight measurement unit 8, the weight on the pressing mechanism 3 can be quickly and conveniently adjusted to any required preset weight. The whole process can be fully automated, with high precision and low cost.

[0070] In another feasible embodiment, the pressing mechanism 3 can be lowered first by the lifting mechanism 4, so that the plate pressing surface of the pressing mechanism 3 is pressed on the insulating glass 1 on the supporting surface 21 by gravity, and then the weight on the pressing mechanism 3 is increased to reach the preset weight.

[0071] S103: After the plate pressing surface 31 of the pressing mechanism 3 presses on the insulating glass 1 on the supporting surface 21 and meets the preset conditions, the plate pressing surface 31 of the pressing mechanism 3 is removed from the insulating glass 1 on the supporting surface 21.

[0072] In this step, in some embodiments, before or during the process of removing the plate pressing surface 31 of the pressing mechanism 3 from the insulating glass 1 on the supporting surface 21, the weight on the pressing mechanism 3 can be reduced. In this way, if the pressing mechanism is lifted by the lifting mechanism 4, the power of the lifting mechanism 4 can be reduced, especially when the total weight on the pressing mechanism 3 is large.

[0073] When the weight on the pressing mechanism 3 is reduced to having no counterweight blocks or no fluid in the first storage unit 32 before the plate pressing surface of the pressing mechanism 3 is removed from the insulating glass 1 on the supporting surface 21, the power of the lifting mechanism 4 can be maximally reduced, thereby reducing the cost of the lifting mechanism 4.

[0074] When the pressing mechanism 3 has a first storage unit 32 for loading fluid, it is convenient and fast to reduce the weight of the pressing mechanism 3 during the process of moving the plate pressing surface 31 of the pressing mechanism 3 away from the insulating glass 1 on the supporting surface 21, and only the pump device 52 needs to be turned on.

[0075] When the pressing mechanism 3 has a first storage unit 32 for loading fluid, before moving the plate pressing surface 31 of the pressing mechanism 3 away from the insulating glass 1 on the supporting surface 21 or during the process of moving the plate pressing surface 31 of the pressing mechanism 3 away from the insulating glass 1 on the supporting surface 21, the on-off valve 55 can be opened to discharge the fluid in the first storage unit 32 to the second storage unit 51 or directly discharge the fluid in the first storage unit 32, so as to reduce the weight of the pressing mechanism 3.

[0076] In the way of discharging the fluid in the first storage unit 32 to the second storage unit 51, the fluid can be recycled to avoid fluid waste and achieve the purpose of cost saving.

[0077] In this step, the preset conditions may include that the plate pressing surface 31 of the pressing mechanism 3 presses on the insulating glass 1 on the supporting surface 21 and the time for maintaining the weight of the pressing mechanism 3 to reach the preset weight reaches the preset time length. Generally speaking, the preset time length can be between 2 seconds and 8 seconds, and can be specifically determined according to factors such as the size of the insulating glass 1, the degree of pressing required, and the weight of the pressing mechanism 3.

[0078] In the embodiment of lowering the pressing mechanism 3 by using the lifting mechanism 4, the preset conditions may include that the lock 7 does not bear the weight of the pressing mechanism 3. In this way, it can be ensured that the weight of the plate pressing surface 31 of the pressing mechanism 3 pressing on the insulating glass 1 is the weight of the pressing mechanism 3, and the lock 7 does not have a pulling force on the pressing mechanism 3. After that, the weight of the pressing mechanism 3 itself can be directly used to apply force to press the first glass and the second glass. Further, since the fluid in the first storage unit 32 can be relatively evenly distributed above the plate pressing surface 31, the applied force is relatively uniform. The structure of the insulating glass gravity pressing device required for the plate pressing method of the insulating glass in the present application is simple and does not require any high-precision mechanism. Compared with the method of using multiple servo motors to drive multiple ball screws to press the first glass and the second glass in the prior art, the whole process of pressing the first glass and the second glass in the present application does not require high coordination and cooperation between different mechanisms, has low precision requirements, and low costs.

[0079] In addition, the plate pressing method of the insulating glass in the present application only presses the first glass sheet and the second glass sheet by using the weight of the pressing mechanism 3, and the fluid in the first storage unit 32 of the pressing mechanism 3 can be adjusted at will by the supply unit 5. Therefore, this device has the advantage of being easy to expand. Especially for large-area insulating glass 1 or extra-large-area insulating glass 1, only the supporting surface 21 of the supporting mechanism 2 and the plate pressing surface 31 of the pressing mechanism 3 need to be enlarged, and the production cost of the whole device is low and simple.
