Description

Technical Field

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

[0002] During the screen bonding process, two flat platforms are typically brought close together, and pressure is used to press the two products together. Most existing bonding equipment achieves screen bonding through the relative movement of two flat platforms. However, due to the inherent flatness errors caused by different screens, and the fact that both platforms of the bonding equipment move in a linear fashion, even if the flatness of the pressing surfaces of the two platforms can be guaranteed, problems with the flatness of the screen after bonding may still occur in actual operation.

[0003] Therefore, there is an urgent need to provide a bonding device to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a bonding device to optimize the structure of the bonding device to a certain extent and solve the technical problem that the alignment and parallelism of the upper and lower platforms are not easy to adjust during the screen bonding process.

[0005] The bonding device provided by this utility model includes an upper platform mechanism and a lower platform mechanism; the upper platform mechanism includes an upper platform body, a first electromagnetic component and a second electromagnetic component, and the lower platform mechanism includes a lower platform body, a third electromagnetic component and a fourth electromagnetic component; the first electromagnetic component is disposed within the platform body, the third electromagnetic component is disposed within the lower platform body, the second electromagnetic component is disposed around the upper platform body, and the fourth electromagnetic component is disposed around the lower platform body.

[0006] The first electromagnetic component includes a first electromagnet and a first electromagnetic wire. A first receiving cavity is formed inside the upper platform body. The first electromagnet is embedded in the first receiving cavity, and the first electromagnetic wire is wound around the first electromagnet.

[0007] Specifically, there are multiple first electromagnets, which are evenly distributed within the upper platform body, and the first electromagnetic wires are arranged in a one-to-one correspondence with the first electromagnets.

[0008] Specifically, the second electromagnetic component includes a plurality of second electromagnets and a second electromagnetic line; the plurality of second electromagnets are evenly distributed circumferentially along the side of the upper platform body, and the second electromagnetic line is arranged in a one-to-one correspondence with the second electromagnet.

[0009] The third electromagnetic component includes a third electromagnet and a third electromagnetic wire. A second receiving cavity is formed within the lower platform body. The third electromagnet is embedded in the second receiving cavity, and the third electromagnetic wire is wound around the third electromagnet.

[0010] Specifically, there are multiple third electromagnets, which are evenly distributed within the lower platform body, and the third electromagnetic lines are arranged in a one-to-one correspondence with the third electromagnets.

[0011] Specifically, the fourth electromagnetic component includes a plurality of fourth electromagnets and a fourth electromagnetic line; the plurality of fourth electromagnets are evenly distributed circumferentially along the side of the lower platform body, and the fourth electromagnetic line is arranged in a one-to-one correspondence with the fourth electromagnet.

[0012] The bonding device provided by this utility model further includes a bonding cavity, in which the upper platform mechanism and the lower platform mechanism are both disposed. The second electromagnetic component is embedded in the wall of the bonding cavity corresponding to the position of the upper platform body around the circumference of the upper platform body. The fourth electromagnetic component is embedded in the wall of the bonding cavity corresponding to the position of the lower platform body around the circumference of the lower platform body.

[0013] Specifically, both the upper platform body and the lower platform body have a plate-like structure.

[0014] Specifically, the upper platform body has a positioning recess, and the lower platform body has a mating protrusion corresponding to the position of the positioning recess, the mating protrusion being able to enter the positioning recess.

[0015] Compared with the prior art, the bonding device provided by this utility model has the following advantages:

[0016] The bonding device provided by this utility model includes an upper platform mechanism and a lower platform mechanism; the upper platform mechanism includes an upper platform body, a first electromagnetic component and a second electromagnetic component, and the lower platform mechanism includes a lower platform body, a third electromagnetic component and a fourth electromagnetic component; the first electromagnetic component is disposed within the platform body, the third electromagnetic component is disposed within the lower platform body, the second electromagnetic component is disposed around the upper platform body, and the fourth electromagnetic component is disposed around the lower platform body.

[0017] This analysis shows that by using a first electromagnetic component located within the upper platform and a second electromagnetic component located within the lower platform, when both components are energized, a movement occurs between the upper and lower platform bodies, causing them to approach or move away from each other. This achieves the pressing and bonding of the screen between the upper and lower platform bodies. It can be understood that controlling the input current increases the magnetic force, thereby adjusting the pressure during the pressing process and ensuring a tight bond.

[0018] Furthermore, by further configuring the third electromagnetic component circumferentially around the upper platform body and the fourth electromagnetic component circumferentially around the lower platform body in this application, the positions of the upper platform body and the lower platform body in the horizontal direction can be limited and changed.

[0019] When the electromagnetic forces provided by the third electromagnetic component surrounding the upper platform are all equal, the upper platform can maintain its predetermined position. Similarly, when the electromagnetic forces provided by the fourth electromagnetic component surrounding the lower platform are all equal, the lower platform can maintain its predetermined position; that is, the upper and lower platform bodies maintain corresponding and parallel positions. When a pressing operation is required, by energizing the first and / or second electromagnetic components with different current directions, different magnetic fields are generated by the first and second electromagnetic components. Based on the principle that opposite magnetic fields attract and like magnetic fields repel, the upper and lower platform bodies can approach each other and achieve stable pressing.

[0020] When there is an error in the flatness of the pressed screen, the pressure between the two components can be adjusted by changing the current supplied to the first and second electromagnetic components. This allows the upper and lower platform bodies to adapt to the screen's error, meaning that the levelness of both the upper and lower platform bodies can be adjusted. This ensures the pressing quality and avoids the problem of unqualified products after pressing due to screen errors. Attached Figure Description

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0026] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, or be held in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The following reference Figure 1 As shown, this utility model provides an upper platform mechanism and a lower platform mechanism; the upper platform mechanism includes an upper platform body 1, a first electromagnetic component and a second electromagnetic component, and the lower platform mechanism includes a lower platform body 5, a third electromagnetic component and a fourth electromagnetic component; the first electromagnetic component is disposed within the platform body, the third electromagnetic component is disposed within the lower platform body 5, the second electromagnetic component is disposed around the upper platform body 1, and the fourth electromagnetic component is disposed around the lower platform body 5.

[0031] Compared with the prior art, the bonding device provided by this utility model has the following advantages:

[0032] The bonding device provided by this utility model, through a first electromagnetic component disposed in the upper platform body 1 and a second electromagnetic component disposed in the lower platform body 5, enables the upper platform body 1 and the lower platform body 5 to move closer or further apart when energized, thereby achieving the pressing and bonding of the screen between the upper platform body 1 and the lower platform body 5. It can be understood that by controlling the magnitude of the input current, the magnetic force can be increased, thereby adjusting the pressure during the screen pressing process and ensuring a tight bond.

[0033] Furthermore, by further providing a third electromagnetic component circumferentially arranged on the upper platform body 1 and a fourth electromagnetic component circumferentially arranged around the lower platform body 5 in this application, the positions of the upper platform body 1 and the lower platform body 5 in the horizontal direction can be limited and changed.

[0034] When the electromagnetic forces provided by the third electromagnetic components surrounding the upper platform body 1 are all equal, the upper platform body 1 can be maintained in a predetermined position. Similarly, when the electromagnetic forces provided by the fourth electromagnetic components surrounding the lower platform body 5 are all equal, the lower platform body 5 can be maintained in a predetermined position. That is, the upper platform body 1 and the lower platform body 5 are maintained in corresponding and parallel positions. When a pressing operation is required, by energizing the first electromagnetic component and / or the second electromagnetic component with different current directions, the first electromagnetic component and the second electromagnetic component can generate different magnetic fields. According to the principle that opposite magnetic fields attract and like magnetic fields repel, the upper platform body 1 and the lower platform body 5 can be brought closer together and pressed stably.

[0035] When there is an error in the flatness of the pressed screen, the pressure between the two can be adjusted by changing the current supplied to the first electromagnetic component and the second electromagnetic component. This allows the upper platform body 1 and the lower platform body 5 to adapt to the error of the screen, meaning that the levelness of both the upper platform body 1 and the lower platform body 5 can be adjusted. This ensures the pressing quality and avoids the problem of unqualified products after pressing due to screen errors.

[0036] It should be further explained here that the distance between the upper platform body 1 and the lower platform body 5 in this application is maintained such that when the upper platform body 1 is freed from the influence of the magnetic field generated by the third magnetic field component, it can just make contact with the screen. That is, the bonding device provided in this application is only affected by the first and second electromagnetic components installed inside itself during the pressing process. It can be understood that when the lower platform body 5 does not move, the fourth electromagnetic component does not generate a magnetic field, and therefore will not affect the pressing process of the upper platform body 1. After the pressing operation is completed, by changing the current direction of the upper platform body 1 or the lower platform body 5, the first and second electromagnetic components can generate the same magnetic poles, and then the electromagnetic repulsion force can be used to move the upper platform body 1 away from the lower platform body 5, waiting for the next pressing operation.

[0037] Optionally, such as Figure 1 As shown, the first electromagnetic component in this application includes a first electromagnet 2 and a first electromagnetic wire 3. A first receiving cavity is formed in the upper platform body 1, the first electromagnet 2 is embedded in the first receiving cavity, and the first electromagnetic wire 3 is wound around the first electromagnet 2.

[0038] By winding the first electromagnetic wire 3 around the first electromagnet 2, the first electromagnet 2 can form a magnetic field after being energized, thereby achieving the above-mentioned function. Different magnetic fields can be formed by passing current in different directions, thereby realizing the screen pressing operation by utilizing the principle of like poles repelling and unlike poles attracting.

[0039] By providing a first receiving cavity within the upper platform body 1, the first electromagnet 2 can have a stable installation space. Preferably, the volume of the first receiving cavity in this application is adapted to the volume and outline of the first electromagnet 2, thereby preventing the first electromagnet 2 from moving around within the first receiving cavity and causing the magnetic field to shift.

[0040] Optionally, such as Figure 1 As shown, there are multiple first electromagnets 2 in this application, and the multiple first electromagnets 2 are evenly distributed in the upper platform body 1, and the first electromagnetic wires 3 are arranged in a one-to-one correspondence with the first electromagnets 2.

[0041] A more uniform magnetic field can be formed by multiple first electromagnets 2 evenly distributed within the upper platform body 1. Since the first electromagnetic wires 3 are set one-to-one with the first electromagnets 2, the magnitude and direction of the magnetic field can be adjusted according to specific operational requirements, thereby better adapting to the screen body, reducing the impact of screen body errors on the pressing process, and improving the product qualification rate.

[0042] Optionally, such as Figure 1As shown, the second electromagnetic component in this application includes a plurality of second electromagnets 4 and a second electromagnetic line; the plurality of second electromagnets 4 are evenly distributed circumferentially along the side of the upper platform body 1, and the second electromagnetic line is arranged in a one-to-one correspondence with the second electromagnet 4.

[0043] The outline of the upper platform body 1 in this application can be rectangular or circular. A regular shape makes it easier to process and manufacture and distribute the magnetic field. Correspondingly, by using the second electromagnet 4 evenly distributed around the upper platform body 1 in the circumference, the force on the upper platform body 1 can be more uniform and the adjustment process can be more stable. At the same time, it can also realize the horizontal movement of the upper platform body 1.

[0044] Taking the cross-section of the platform body 1 as a rectangle as an example, the second electromagnet 4 in this application can be arranged at the center positions of the four sides. When it is necessary to make the upper platform body 1 move horizontally, the magnetic field formed by the two second electromagnets 4 corresponding to the two parallel sides of the upper platform body 1 can be formed according to the magnetic field formed by the first electromagnet 2 in the upper platform body 1.

[0045] Understandably, with Figure 1 Taking the direction shown in the diagram as an example, when the upper platform body 1 needs to move to the left, and the magnetic field formed by the first electromagnet 2 inside the upper platform body 1 is the left-end S pole and the right-end N pole, then the second electromagnet 4 corresponding to the left-end S pole forms an S pole magnetic field, and the second electromagnet 4 corresponding to the right-end N pole also forms an S pole magnetic field, thus enabling the upper platform body 1 to move to the left. Similarly, when it needs to move to the right, the direction of the magnetic field can be adjusted.

[0046] It should be noted that in this application, there are multiple first electromagnets 2 in the upper platform body 1 and multiple third electromagnets 6 in the lower platform body 5, and multiple layers can be set. That is, the layer in the upper platform body 1 that is close to the lower platform body 5 only participates in the vertical movement of the upper platform body 1. Therefore, the first electromagnets 2 in this layer can be set along the vertical direction, so as to form a more obvious magnetic field direction and magnetic pole orientation, which facilitates the control of vertical movement.

[0047] The upper layer only participates in the horizontal movement of the upper platform body 1. Therefore, taking the upper layer as an example with four first electromagnets 2 and the upper platform body 1 being rectangular, two first electromagnets 2 are arranged opposite each other at both ends of the upper platform body 1 along the length direction of the upper platform body 1, while the other two first electromagnets 2 are arranged opposite each other on both sides of the upper platform body 1 along the width direction of the upper platform body 1, forming an approximately cross-shaped arrangement, thereby enabling the upper platform body 1 to move horizontally.

[0048] Therefore, when it is necessary to move the upper platform body 1 in the horizontal direction, the upper first electromagnet 2 can be used first. After it is moved into place, the lower first electromagnet 2 can be used to move it in the vertical direction.

[0049] Optionally, such as Figure 1 As shown, the third electromagnetic component in this application includes a third electromagnet 6 and a third electromagnetic wire 7. A second receiving cavity is formed in the lower platform body 5. The third electromagnet 6 is embedded in the second receiving cavity, and the third electromagnetic wire 7 is wound around the third electromagnet 6.

[0050] The third electromagnet 6 installed inside the lower platform body 5 can work with the first electromagnet 2 to form a more uniform magnetic field during actual operation, while also supplementing the pressure on the screen to ensure a good fit.

[0051] Optionally, such as Figure 1 As shown, there are multiple third electromagnets 6 in this application. The multiple third electromagnets 6 are evenly distributed in the lower platform body 5, and the third electromagnetic wires 7 are arranged in a one-to-one correspondence with the third electromagnets 6.

[0052] By setting multiple third electromagnets 6 inside the lower platform body 5, and setting the third electromagnetic wires 7 in a one-to-one correspondence with the third electromagnets 6, a more flexible adjustment method can be achieved, making the compatibility between the lower platform body 5 and the upper platform body 1 higher. Moreover, the one-to-one correspondence arrangement ensures that the multiple third electromagnets 6 do not affect each other, making it easier to control the magnetic field.

[0053] Optionally, such as Figure 1 As shown, the fourth electromagnetic component in this application includes a plurality of fourth electromagnetic bodies 8 and a fourth electromagnetic wire; the plurality of fourth electromagnetic bodies 8 are evenly distributed circumferentially along the side of the lower platform body 5, and the fourth electromagnetic wire is arranged in a one-to-one correspondence with the fourth electromagnetic body 8.

[0054] In this application, the lower platform body 5 is preferably consistent with the outline and size of the upper platform body 1, so as to better control the positional correspondence. The arrangement and number of the third electromagnet 6 inside the lower platform body 5 and the corresponding fourth electromagnet 8 on the side circumferential direction are the same as those of the first electromagnet 2 and the second electromagnet 4 mentioned above, so as to ensure the uniformity of force distribution, which will not be elaborated here.

[0055] Optionally, the film-applying device provided by this utility model further includes an applicating cavity, with both the upper platform mechanism and the lower platform mechanism disposed within the applicating cavity, and the second electromagnetic component being embedded in the wall of the applicating cavity at the position corresponding to the upper platform body 1 around the circumference of the upper platform body 1; and the fourth electromagnetic component being embedded in the wall of the applicating cavity at the position corresponding to the lower platform body 5 around the circumference of the lower platform body 5.

[0056] The bonding cavity provides a stable installation space for the upper and lower platform mechanisms. Furthermore, the bonding cavity in this application can also form a vacuum, which can isolate external impurities to a certain extent and improve the bonding effect.

[0057] Based on the above structure, such as Figure 1 As shown, both the upper platform body 1 and the lower platform body 5 in this application have a plate-like structure.

[0058] The upper platform body 1 and the lower platform body 5, which are plate-shaped, can be adapted to the flat screen structure, providing a better pressing effect for the plate-shaped screen.

[0059] In another embodiment of this application, the upper platform body 1 has a positioning recess, and the lower platform body 5 has a mating protrusion at the position corresponding to the positioning recess, and the mating protrusion can enter the positioning recess.

[0060] The positioning recess in this application has a space that is nearly arched. Correspondingly, the shape of the mating protrusion formed by the lower platform body 5 is the same as the shape of the positioning recess, so as to correspond to the curved screen body and realize the pressing of the curved screen body.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
