Description

Technical Field

[0001] This utility model relates to the field of patch material bonding technology, and in particular to a patch bonding device. Background Technology

[0002] Currently, factory operators use a manual blind application method. When using the patch, the operator must attach it to the surface of the cover plate system to be applied, such as a mobile phone screen. After application, the operator uses a roller to roll up and down twice at the application position to achieve a complete fit, and then removes the release film from the patch.

[0003] This blind application method has significant drawbacks. When applied manually, the patches cannot be accurately aligned, resulting in misaligned or uneven patches. In particular, flexible patches are prone to wrinkling, which can lead to air bubbles around the product. Summary of the Invention

[0004] In view of this, the purpose of this utility model embodiment is to provide a patch bonding device that can achieve accurate alignment, neat patch bonding, and reduce air bubbles.

[0005] To address one of the aforementioned problems, this utility model proposes a patch bonding device, comprising:

[0006] The bonding device includes a sealing plate, a product placement plate, and a suction component. The sealing plate and the product placement plate are bonded together to form a suction clamp. A suction cavity is formed between the sealing plate of the suction clamp and the product placement plate. The suction cavity is connected to the suction component.

[0007] The product placement plate is provided with a patch positioning groove, which is connected to the air intake cavity.

[0008] The air intake component is connected to the air intake cavity.

[0009] Optionally, a sealing ring is provided on the sealing plate, and the sealing ring is attached to the product placement plate.

[0010] Optionally, the size of the sealing ring is greater than or equal to the size of the intake chamber.

[0011] Optionally, the sealing ring includes at least one layer of rubber.

[0012] Optionally, the product placement plate is provided with a product positioning groove, and the patch positioning groove is located within the product positioning groove.

[0013] Optionally, the bonding device further includes a pressing assembly and a base. The pressing assembly is disposed on the base, and the base has a placement platform for placing the suction clamp. The pressing assembly can be moved to a position where it presses against the suction clamp.

[0014] Optionally, the pressing assembly includes a gas pressure regulating valve, a cylinder, a first gas pipe, and a pressure head; the cylinder is fixed on the base.

[0015] One end of the first air tube is connected to the gas pressure regulating valve, and the other end of the first air tube is connected to the cylinder; the pressure head is connected to the cylinder, and the pressure head can be moved to a position where it is pressed against the suction clamp.

[0016] Optionally, the bottom of the pressure head has at least one layer of flexible material.

[0017] Optionally, the pressing assembly further includes a gas source control switch, a gas pipe connection assembly, and a second gas pipe; the gas source control switch is fixed on the base.

[0018] The gas source control switch is connected to one end of the second gas pipe, the other end of the second gas pipe is connected to the gas pipe connection assembly, and the gas pipe connection assembly is connected to the gas pressure regulating valve.

[0019] Optionally, the bonding device further includes a cylinder support plate and a cylinder fixing plate, the cylinder is fixed on the cylinder fixing plate, the cylinder support plate and the cylinder fixing plate are fixed on the base, and the cylinder support plate and the cylinder fixing plate are connected by screws.

[0021] This invention offers the following advantages: An air intake chamber is formed between the sealing plate and the product placement plate. This chamber is connected to the air intake component. The product placement plate has a patch positioning groove that communicates with the air intake chamber. When using this device, placing the patch into the patch positioning groove aligns the patch with the groove, achieving edge alignment and reducing the possibility of misalignment or unevenness, thus improving bonding accuracy. Then, the air intake component is activated. It absorbs gas from the air intake chamber, reducing the pressure inside the chamber to be lower than the pressure outside the product placement plate, thus adsorbing and fixing the patch flat and securely in the patch positioning groove, reducing patch wrinkles and air bubbles.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. It is worth noting that in this utility model, "a number" means "one" or more.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0035] To address the technical problems existing in the current technology, the following will be combined with the appendix. Figures 1 to 10 The patch bonding device provided in the embodiments of this utility model will be described in detail.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of an assembly of a bonding device provided by this utility model. Figure 2 This is a structural schematic diagram of a product placement plate; the bonding device provided by this utility model includes a sealing plate, a product placement plate, and an air suction component. The sealing plate and the product placement plate are bonded together to form an air suction clamp. An air suction cavity is formed between the sealing plate of the air suction clamp and the product placement plate, and the air suction cavity is connected to the air suction component.

[0037] The product placement plate is equipped with a patch mounting slot, which is connected to the suction chamber; the suction component is connected to the suction chamber.

[0038] The sealing plate and the product placement plate can be bonded together to form the suction clamp in one piece or by using an adhesive material. The suction component can be, but is not limited to, a suction valve.

[0039] Specifically, such as Figure 3 As shown, Figure 3This is a structural diagram of a sealing plate. When the sealing plate and the product placement plate are not integrally formed, a sealing ring is provided on the sealing plate. The sealing ring adheres to the product placement plate. Optionally, the size of the sealing ring can be greater than or equal to the size of the suction chamber, where the size includes the length of each side. The shape of the sealing ring can be the same as or different from the shape of the suction chamber. For example, the sealing ring can be a circular sealing ring with a diameter of 2mm, and the suction chamber can be a polyhedron with a width of 2.2mm and a depth of 1.8mm. The sealing ring may include at least one layer of rubber.

[0040] In this superior solution, adding a sealing ring to the sealing plate improves gas sealing and reduces gas leakage due to poor sealing during adsorption.

[0041] Specifically, such as Figure 1-2 As shown, the product placement plate is provided with product positioning slots, and the patch positioning slots are located inside the product positioning slots.

[0042] The patch mounting slot has several through holes, each penetrating the product placement plate and connecting to the suction chamber. The patch mounting slot is used to place and hold the patch, which can be, but is not limited to, a flexible material patch. The product mounting slot is used to place and fix the product to be patched. The product mounting slot can be composed of several protruding parts on the product placement plate, or it can be integrally formed with the product placement plate, for example, by chiseling a groove into the product placement plate.

[0043] The surface mount mounting slot is located within the product mounting slot, and the size of the surface mount mounting slot can be smaller than or equal to the size of the product mounting slot. For example... Figure 1 For example, the patch mounting slot is located at the upper end of the product mounting slot, and the size of the patch mounting slot is smaller than that of the product mounting slot.

[0044] Product alignment slots can be used for product edge alignment, and patch alignment slots can be used for patch edge alignment. This double alignment not only ensures the patch is flat and not skewed, reducing air bubbles, but also improves the accuracy of the patch's adhesion to the product. Edge alignment can be explained as aligning the patch with one or more sides of the patch alignment slot, or aligning the product with one or more sides of the patch alignment slot.

[0045] After the suction component is activated, the suction chamber forms a negative pressure, which adsorbs the patch through the through hole of the patch positioning groove, making it flat and adhered to the groove; when the pressing component is activated, the cylinder drives the pressure head to press down with constant pressure, and the flexible material layer evenly distributes the pressure to prevent the patch from shifting.

[0046] In a better solution, several through holes are evenly distributed to achieve uniform air intake and make the patch flatter.

[0047] The aforementioned bonding device features a simplified structural design, making parts assembly and replacement convenient and reducing the operator's assembly time.

[0048] like Figure 4-5 As shown, Figure 4 This is a diagram of a bonding device after the patch is aligned to the edge. Figure 5 This is a diagram of a bonding device for aligning a product with its edge. The bonding device can align the patch with the product.

[0049] In some embodiments, such as Figure 6-7 As shown, Figure 6 This is a front view diagram of another bonding device. Figure 7 This is a schematic diagram of the back structure of another bonding device. This utility model also provides another bonding device, which includes the aforementioned bonding clamp, suction component, pressing component and base, and can realize automatic patch application by using the pressing component.

[0050] The pressing assembly is mounted on a base, which has a platform for placing the suction clamp. The pressing assembly can be moved to a position where it presses against the suction clamp. For example, the platform can be, but is not limited to, a base plate, which can be locked to the base using, but is not limited to, screws or other locking devices.

[0051] Specifically, the pressing assembly includes a gas pressure regulating valve, a cylinder, a first air pipe, and a pressing head; the cylinder is fixed on the base; one end of the first air pipe is connected to the gas pressure regulating valve, and the other end of the first air pipe is connected to the cylinder; the pressing head is connected to the cylinder, and the pressing head can be moved to a position where it is pressed against the suction clamp.

[0052] The first air pipe includes at least three air pipes. One end of one air pipe is connected to a gas pressure regulating valve, and the other end is connected to two other air pipes, enabling multi-channel adjustment of the air pressure within the cylinder. The other two air pipes are connected to the cylinder at their respective ends. The gas in the cylinder drives the pressure head to move, and the gas pressure in the cylinder is used to regulate the pressure of the pressure head on the suction clamp. The gas pressure regulating valve and the cylinder maintain pressure on the bonded products, achieving the effect of maintaining stable pressure on each product under the same pressure.

[0053] In a better solution, the pressure head is first fixed to the adapter plate, and the adapter plate is then locked to the cylinder using screws or other locking devices.

[0054] The bottom of the pressure head has at least one layer of flexible material to reduce scratches on the product. The flexible material layer can be a cotton pad, a soft rubber, or a combination of several layers of cotton pad and several layers of soft rubber.

[0055] In some embodiments, such as Figure 8 As shown, Figure 8This is a schematic diagram of the installation of a pressing assembly in a base. The pressing assembly also includes an air source control switch, an air pipe connection assembly, and a second air pipe; the air source control switch is fixed on the base.

[0056] The gas source control switch is connected to one end of the second gas pipe, the other end of the second gas pipe is connected to the gas pipe connection assembly, and the gas pipe connection assembly is connected to the gas pressure regulating valve and the first gas pipe.

[0057] The second air pipe has at least three air pipes. The gas source in the cylinder is adjusted by the air source control switch and the air pipe connection assembly. The air source control switch can open one air pipe to supply air, or it can open two air pipes to supply air, or it can open three air pipes to supply air.

[0058] The gas source connection assembly and gas source control switch can be fixed to the base with screws.

[0059] In some embodiments, such as Figure 6 and 7 As shown, the bonding device also includes a cylinder support plate and a cylinder fixing plate. The cylinder is fixed on the cylinder fixing plate, and the cylinder support plate and the cylinder fixing plate are fixed on the base. The cylinder support plate and the cylinder fixing plate are connected by screws.

[0060] Specifically, the cylinder support plate and the cylinder fixing plate can be fixed to the base with screws or other locking devices. The cylinder fixing plate can be fixed to the cylinder support plate with screws or other locking devices to provide support. The cylinder can also be fixed to the cylinder fixing plate with screws or other locking devices.

[0061] In some embodiments, the sealing plate, product placement plate, suction component, and base are all made of aluminum alloy. Other components of the pressing assembly, except for the pressure head, can also be made of aluminum alloy. Using aluminum alloy can improve the service life of the device.

[0062] like Figure 9-10 As shown, Figure 9 This is a schematic diagram of a patch product structure. Figure 10 This is a structural diagram of a flexible gasket. Taking a flexible gasket and a glass cover as examples, the application process of this bonding device can be as follows:

[0063] Place the flexible gasket with the release film into the mounting slot of the suction fixture, with the release film facing down and aligned against the edge of the mounting slot. After aligning, open the suction valve to fix the flexible gasket in place. Place the glass cover plate into the product mounting slot of the suction fixture and align it to the flexible gasket.

[0064] Move the suction clamp holding the glass cover to the right-angled edge of the placement table, adjust the appropriate pressure, turn on the air source control switch, and move the pressure head downwards to press. After pressing, turn off the air source control switch, move the pressure head upwards, remove the laminated glass cover, and peel off the release film.

[0065] This utility model provides a bonding device, and it should be noted that this utility model has the following beneficial effects:

[0066] 1. When using this device, place the patch into the patch alignment slot to align the patch with the slot, achieving edge alignment and reducing the possibility of patch misalignment or unevenness, thus improving bonding accuracy. Then, turn on the suction component. The suction component can absorb the gas in the suction chamber, making the pressure in the suction chamber lower than the outside of the product placement plate, thus suctioning the patch and fixing it flat and in place in the patch alignment slot, reducing patch wrinkles and thus reducing air bubbles.

[0067] 2. Adding a sealing ring to the sealing plate improves gas sealing and reduces gas leakage due to poor sealing during adsorption.

[0068] 3. Product positioning grooves can be used for product edge alignment, and patch positioning grooves can be used for patch edge alignment. This double alignment not only ensures that the patch is flat and not skewed, reducing air bubbles, but also improves the accuracy of the patch being attached to the product.

[0069] 4. Use cylinders and gas pressure regulating valves to control the pressure head to maintain pressure on the pasted products, so that each product is stably pasted under the same pressure.

[0070] 5. The bottom of the pressure head has at least one layer of flexible material, which can reduce scratches on the product.

[0071] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
