Description

Technical Field

[0001] This invention relates to the field of smartwatch assembly technology, and more particularly to a vacuum bonding device. Background Technology

[0002] With the advancement of technology, smartwatches have become increasingly popular due to their exquisite design, attractive appearance, and rich functionality. The watch face of a smartwatch typically consists of a lower dial housing and an inner lining, which need to be securely connected during the assembly process.

[0003] The lower dial of the smartwatch has a square structure with rounded corners and recessed interiors forming an open, fitted area. This area is divided into two parts: a flat, centrally located planar portion and a curved, recessed portion surrounding the planar portion. The inner lining has raised, platform-like fitted areas that align with the lower dial's fitted area. The inner lining's fitted area completely covers the planar portion of the lower dial, with some parts contacting the curved area. Both the inner lining and the lower dial are made of transparent glass.

[0004] The traditional method of connecting the lower dial and the inner liner is to glue them together with double-sided tape. However, due to issues such as efficiency and connection quality, this method has been replaced by adhesive dispensing. However, existing adhesive dispensing devices, when bonding the two, need to adhere the inner liner and the lower dial without contacting the first and second bonding areas, making it difficult to ensure uniform adhesion between the inner liner and the lower dial, resulting in bonding quality problems. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the difficulty of ensuring the bonding quality of the lower dial and the inner lining by existing dispensing bonding devices, and to provide a vacuum bonding device that can make the lower dial and the inner lining bond evenly, with no air bubbles or impurities in the adhesive, thus ensuring high bonding quality.

[0006] This invention provides a vacuum bonding device for bonding a lower dial and an inner liner. The lower dial has a first bonding area, and the inner liner has a second bonding area adapted to the first bonding area. The vacuum bonding device includes a vacuum chamber bonding apparatus, which includes a vacuum chamber housing, comprising a vacuum containing cavity and a chamber opening communicating with the vacuum containing cavity; a vacuum door, comprising a door body, a door moving assembly, and a door platform, the door body being connected to the door moving assembly and the door platform respectively, the door moving assembly driving the door platform into the vacuum containing cavity and sealing the chamber opening with the door body; and an ultraviolet curing lamp, which is movably disposed within the vacuum containing cavity. The first fixing component includes a lower dial fixing fixture and a fixing drive component, the fixing drive component being disposed on the door platform, and the lower dial fixing fixture being connected to the fixing drive component; the second fixing component includes an inner lining fixing fixture, a fixing rotating component, and a fixing lifting component, the fixing lifting component being disposed on the door platform, and the fixing rotating component being connected to the fixing lifting component; the inner lining fixing fixture includes a fixture connecting plate and an inner lining fixing component, the fixture connecting plate being connected to the fixing rotating component and the inner lining fixing component respectively, and the fixture connecting plate having multiple through holes around the inner lining fixing component, the through holes being used for the light from the ultraviolet curing lamp to pass through and form a pre-fixation when the inner lining and the lower dial are attached.

[0007] In one embodiment of the present invention, the door moving assembly includes a first door moving component, a door upright plate, and a second door moving component. The first door moving component is fixedly disposed, and the door upright plate is connected to the first door moving component and the second door moving component respectively. The second door moving component is connected to the door body.

[0008] In one embodiment of the present invention, the door moving assembly further includes a blocking component, which includes a blocking cylinder, a blocking guide rod, and a blocking guide sleeve. The blocking cylinder is fixedly disposed, the blocking guide rod is connected to the driving end of the blocking cylinder, and the blocking guide sleeve is connected to the door upright plate. When the first door moving component moves into position, the blocking cylinder drives the blocking guide rod to abut against the blocking guide sleeve, thus limiting the position of the door upright plate. The second door moving component drives the door body to seal the opening of the box.

[0009] In one embodiment of the present invention, a bonding image acquisition device is further included. The bonding image acquisition device is disposed above the vacuum chamber and is used for positioning detection of the lower dial and the inner liner before and after bonding. A viewing window adapted to the bonding image acquisition device is provided on the vacuum chamber, and an alignment platform is provided between the lower dial fixing fixture and the fixing drive component. Before the ultraviolet curing lamp performs pre-curing, the bonding image acquisition device detects the relative center position of the lower dial and the inner liner through the viewing window and through-hole, and adjusts the relative center position of the lower dial and the inner liner through the alignment platform. After the ultraviolet curing lamp completes full curing, the ultraviolet curing lamp moves away, and the bonding image acquisition device detects the relative center position of the lower dial and the inner liner through the viewing window.

[0010] In one embodiment of the present invention, a laser inspection device is further included. The laser inspection device is disposed above the vacuum chamber and is used for inspection before and after the lower dial and the inner liner are bonded. A height adjustment platform is provided between the lower dial fixing fixture and the fixing drive component. Before dispensing adhesive, the laser inspection device inspects the thickness of the lower dial and the inner liner, as well as the distance between the lower dial and the inner liner, and adjusts the distance between the lower dial and the inner liner using the height adjustment platform. After the ultraviolet curing lamp has completed full curing, the laser inspection device inspects the distance between the lower dial and the inner liner after bonding.

[0011] In one embodiment of the present invention, a feeding device and a picking device are further included. The picking device is used for picking and transporting materials before the lower dial and the inner lining are glued, and for unloading and transporting materials after bonding is completed. The feeding device includes a first material tray for accommodating the lower dial and a second material tray for accommodating the inner lining. Both the first material tray and the second material tray are provided with multiple material positions. Each material position is provided with a feeding clearance space for the picking device to pick up materials. When the lower dial and the inner lining are located at the material positions, both the first bonding area and the second bonding area are vertically upward.

[0012] In one embodiment of the present invention, the feeding device includes a feeding bracket, a material plate driving component, a first material tray carrier plate, and a second material tray carrier plate. The feeding bracket is fixedly arranged, and the first material tray carrier plate and the second material tray carrier plate are sequentially arranged on the feeding bracket along the height direction and are respectively connected to the material plate driving component. The material plate driving component is used to drive the first material tray carrier plate and the second material tray carrier plate to move along the horizontal direction of the feeding bracket. The first material tray carrier plate and the second material tray carrier plate are each provided with a first material tray and a second material tray.

[0013] In one embodiment of the present invention, a feeding image acquisition device is further included, which is connected to the feeding device and is used for detection during feeding of the lower dial and the lining.

[0014] In one embodiment of the present invention, a cleaning device is further included. The cleaning device includes a cleaning drive component and a cleaning assembly. The cleaning assembly is fixedly disposed. The cleaning drive component is used to transport the lower dial and the inner lining to the cleaning assembly and to clean the first bonding area and the second bonding area before loading the material through the cleaning assembly.

[0015] In one embodiment of the present invention, a dispensing device is further included. The dispensing device includes a dispensing driving component, a dispensing image acquisition component, and a dispensing assembly. The dispensing driving component is fixedly disposed, and the dispensing image acquisition component and the dispensing assembly are both connected to the dispensing driving component. Specifically, before dispensing, the dispensing driving component drives the dispensing image acquisition component to move above the lower dial for positioning, and then the dispensing assembly performs the dispensing.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] The vacuum bonding equipment of this invention provides a vacuum environment for adhesive dispensing through the vacuum chamber and vacuum chamber door in the vacuum chamber bonding device, ensuring that the adhesive evenly and fully covers the required portion of the first bonding area. The movable ultraviolet curing lamp, in conjunction with the first and second curing components, enables step-by-step curing and bonding of the lining and lower dial without contacting the first and second bonding areas, guaranteeing uniform adhesive dispensing, no air bubbles or impurities, and high-quality bonding.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0034] This invention discloses a vacuum bonding device for bonding the lower dial 10 and the inner liner 20. (Refer to...) Figure 2As shown, the lower dial 10 has a first fitting area 11, and the inner liner 20 has a second fitting area 21 that matches the first fitting area 11. Both the lower dial 10 and the inner liner 20 are made of transparent glass. The first fitting area 11 includes a flat, centrally located planar portion and an arc-shaped recessed portion surrounding the planar portion. The second fitting area 21 is configured as a boss-like structure that matches the first fitting area 11. It should be noted that... Figure 2 The lower dial 10 and inner lining 20 shown are merely schematic diagrams created for the purpose of understanding the technical solution.

[0035] Reference Figure 1 As shown, the vacuum bonding equipment of the present invention includes a vacuum cavity bonding device 30. The vacuum cavity bonding device 30 includes a vacuum chamber 31, which includes a vacuum containing cavity 311 and a chamber opening 312 communicating with the vacuum containing cavity 311; a vacuum door 32, which includes a door body 321, a door moving assembly 322, and a door platform 323. The door body 321 is connected to the door moving assembly 322 and the door platform 323 respectively. The door moving assembly 322 is used to drive the door platform 323 into the vacuum containing cavity 311 and to seal the chamber opening 312 with the door body 321; an ultraviolet curing lamp 33, which is movably disposed within the vacuum containing cavity 311; and a first fixing assembly 34, which includes a lower dial fixing fixture 341 and a fixing drive component 342. The fixing drive component 342 is disposed within the vacuum containing cavity 311. On the door platform 323, the lower dial fixing fixture 341 is connected to the fixing drive component 342; the second fixing component 35 includes an inner lining fixing fixture 351, a fixing rotating component 352, and a fixing lifting component 353. The fixing lifting component 353 is disposed on the door platform 323, and the fixing rotating component 352 is connected to the fixing lifting component 353; the inner lining fixing fixture 351 includes a fixture connecting plate 3511 and an inner lining fixing component 3513. The fixture connecting plate 3511 connects the fixing rotating component 352 and the inner lining fixing component 3513 respectively, and the fixture connecting plate 3511 has a plurality of through holes 3512 around the inner lining fixing component 3513. The through holes 3512 are used for the light from the ultraviolet curing lamp 33 to pass through and form a pre-fixation when the inner lining 20 and the lower dial 10 are attached.

[0036] The vacuum bonding device is used for vacuum bonding of the lower dial 10 and the inner liner 20. The vacuum bonding device includes a vacuum chamber 31, a vacuum chamber door 32, an ultraviolet curing lamp 33, a first fixing component 34, and a second fixing component 35. (Refer to...) Figure 1 and Figure 7As shown, the vacuum chamber 31 provides a vacuum environment for bonding the lower dial 10 and the inner liner 20. In a vacuum environment, the adhesive has lower viscosity and a certain degree of fluidity, thus ensuring uniform and sufficient coverage of the required area in the first bonding area 11, guaranteeing even adhesive application. The required area in the first bonding area 11 can be configured according to actual bonding requirements; preferably, it covers the entire planar portion of the first bonding area 11 and a portion of the curved surface, ensuring sufficient bonding without adhesive overflow and high bonding quality. Specifically, the vacuum chamber 31 includes a vacuum chamber 311 and a chamber opening 312 communicating with the vacuum chamber 311, allowing the lower dial 10 and the inner liner 20 to enter the vacuum chamber 311 through the chamber opening 312 for bonding. Preferably, it also includes a vacuum pump, a vacuum gauge, and a vacuum breaking component, all of which are existing technologies, and their principles and functions will not be described in detail. (Refer to...) Figure 1 and Figure 3 As shown, the vacuum chamber door 32 includes a door body 321, a door moving assembly 322, and a door platform 323. The door body 321 is connected to both the door moving assembly 322 and the door platform 323. The door moving assembly 322 drives the door platform 323 into the vacuum chamber 311 and seals the door body 321 to form the opening 312 of the chamber. The door platform 323 serves as a support platform for the corresponding components. This structure ensures that the vacuum chamber 311 can achieve a good vacuum, providing a good environment for bonding after dispensing and ensuring high and uniform bonding quality. The door moving assembly 322 can be configured according to actual needs, as long as it can seal the door body 321 and the opening 312 of the chamber; for example, a combination of a cylinder, motor, and lead screw. (Refer to...) Figure 3 As shown, the ultraviolet curing lamp 33, also known as a UV lamp, is an existing technology used for curing adhesives. The ultraviolet curing lamp 33 is movable within the vacuum chamber 311 via a curing lamp drive component 331. This structure effectively coordinates with two fixed components to achieve curing of the lower dial 10 and the inner liner 20 after dispensing, ensuring that every part of the lower dial 10 and the inner liner 20 receives sufficient ultraviolet irradiation, guaranteeing a firm bond while relatively improving bonding efficiency. Depending on different needs, the curing lamp drive component 331 can be configured to allow the ultraviolet curing lamp 33 to move within the vacuum chamber 311, such as through a combination of a cylinder, motor, and lead screw.

[0037] Reference Figure 4 and Figure 5As shown, the first fixing component 34 includes a lower dial fixing fixture 341 and a fixing drive component 342. The fixing drive component 342 is disposed on the door platform 323, and the lower dial fixing fixture 341 is connected to the fixing drive component 342. The lower dial fixing fixture 341 is used to fix the lower dial 10, and the fixing drive component 342 is used to move the lower dial fixing fixture 341. Preferably, the lower dial fixing fixture 341 is a combination of an electrostatic chuck and a fixture plate. The electrostatic chuck can provide a firm adsorption for the lower dial 10 in the vacuum environment of the vacuum chamber 311, avoiding the problem that the vacuum chuck is difficult to effectively adsorb in a vacuum environment. When the lower dial 10 is placed on the lower dial fixing fixture 341, its first bonding area 11 is vertically upward, which facilitates the handling and fixing before dispensing, facilitates rapid dispensing, and facilitates subsequent bonding with the inner liner 20, thereby improving the efficiency of the entire dispensing and bonding process. The fixture plate is provided with a fixed clearance space 3411. By providing the fixed clearance space 3411, it is convenient to handle the material during loading, and the first bonding area 11 is not touched during the handling process. This directly avoids problems such as uneven glue dispensing and uneven bonding caused by damage to the first bonding area 11 due to contact with it. The setting of the fixed drive component 342 allows the lower dial fixing fixture 341 and the inner liner fixing fixture 351 to be set in different positions. This facilitates glue dispensing before bonding and allows the lower dial fixing fixture 341 to be moved below the inner liner fixing fixture 351 for bonding after glue dispensing. The fixed drive component 342 can be set according to actual needs, such as a combination of cylinder, motor and lead screw, etc., as long as it can move the lower dial fixing fixture 341 to facilitate glue dispensing and bonding.

[0038] Reference Figure 4 and Figure 6As shown, the second fixing component 35 includes an inner lining fixing fixture 351, a fixing rotating component 352, and a fixing lifting component 353. The fixing lifting component 353 is mounted on the door platform 323 for raising and lowering the inner lining fixing fixture 351, thereby attaching the inner lining 20 to the lower dial 10. Simultaneously, it allows for precise control of the descent height through sensors, further ensuring the quality of the attachment. The fixing lifting component 353 can be configured according to actual needs, such as using a combination of a cylinder, motor, and lead screw. The fixing rotating component 352 is connected to the fixing lifting component 353 and is used for rotating the inner lining fixing fixture 351. During the loading and handling of the liner 20, its second bonding area 21 must not come into contact with any external solid objects. Therefore, before bonding with the first bonding area 11, the second bonding area 21 is always placed vertically upwards. By setting a fixed rotating component 352, the second bonding area 21 can be flipped from vertically upwards to vertically downwards, thus bonding with the lower dial 10. Simultaneously, sensors can be installed to precisely control the flipping angle, further ensuring bonding quality. The fixed rotating component 352 can be configured according to actual needs, such as a motor. The inner lining fixing fixture 351 includes a fixture connecting plate 3511 and an inner lining fixing component 3513. The fixture connecting plate 3511 connects the fixing rotating component 352 and the inner lining fixing component 3513 respectively. The fixture connecting plate 3511 has multiple through holes 3512 around the inner lining fixing component 3513. The through holes 3512 are used for the light from the ultraviolet curing lamp 33 to pass through and form a pre-fixation when the inner lining 20 and the lower dial 10 are attached. Preferably, the inner lining fixing component 3513 is set as an electrostatic chuck. The electrostatic chuck can provide a firm adsorption for the inner lining 20 in the vacuum environment of the vacuum cavity 311, avoiding the problem that vacuum chucks are difficult to effectively adsorb in a vacuum environment. When the inner liner 20 is placed on the inner liner fixing component 3513, its second bonding area 21 is vertically upward, which facilitates handling and fixing before dispensing and avoids problems such as uneven dispensing and uneven bonding caused by damage to the second bonding area 21 due to contact with it. When the inner liner 20 needs to be bonded to the lower dial 10, it can be flipped by the fixing rotating component 352 and then lowered by the fixing lifting component 353. The fixture connecting plate 3511 provides a connection support for the inner liner fixing component 3513 and the fixing rotating component 352. The multiple through holes 3512 opened around the inner liner fixing component 3513 can be well adapted to the ultraviolet curing lamp 33. Preferably, the vacuum chamber 31 is also provided with an electrostatic elimination component 313 directly above the chamber opening 312 to eliminate static electricity and ensure bonding quality.

[0039] Specifically, when the first bonding area 11 is glued, the entire door platform 323 enters the vacuum containment cavity 311, and the door body 321 forms a seal for the door opening 312, the fixed drive component 342 drives the lower dial fixing fixture 341 to move directly below the inner liner fixing fixture 351, the fixed rotation component 352 drives the inner liner fixing fixture 351 to flip, and the fixed lifting component 353 drives the inner liner fixing fixture 351 to descend, thereby bonding the inner liner 20 and the lower dial 10. Simultaneously, the ultraviolet curing lamp 33, driven by the curing lamp drive component 331, moves to directly above the inner liner fixing fixture 351, and the ultraviolet light passes through the through hole 3512 to pre-cur the inner liner 20 and the lower dial 10. After pre-curing is completed, the inner liner 20 and the lower dial 10 are initially fixed together. At this time, the force of the inner liner fixing fixture 351 is removed, and the pre-cured inner liner 20 and the lower dial 10, as well as the ultraviolet curing lamp 33, are moved by the fixing drive component 342 and the curing lamp drive component 331, so that the ultraviolet curing lamp 33 can completely irradiate the inner liner 20 and the lower dial 10 without being blocked by the inner liner fixing fixture 351, thereby achieving full curing of the inner liner 20 and the lower dial 10 and ensuring that the two are firmly bonded.

[0040] Existing bonding devices often come into contact with the bonding surface of products during bonding, causing some damage such as scratches, dust adhesion, etc. This results in problems like the adhesive not fully contacting every surface to be bonded, uneven adhesive distribution, air bubbles, and impurities within the adhesive, all of which affect the bonding quality. The vacuum bonding equipment described in this invention provides a vacuum environment for adhesive dispensing through the vacuum chamber 31 and vacuum door 32 in the vacuum chamber bonding device 30, ensuring that the adhesive evenly and fully covers the required area in the first bonding area 11. The movable ultraviolet curing lamp 33, in conjunction with the first and second curing components, ensures step-by-step curing and bonding of the inner liner 20 and the lower dial 10 without contacting the first and second bonding areas 11 and 21, guaranteeing uniform adhesive dispensing and bonding without air bubbles or impurities, resulting in high-quality bonding.

[0041] Reference Figure 7 and Figure 8As shown, in some embodiments of the vacuum bonding equipment of the present invention, the door moving assembly 322 includes a first door moving component 3221, a door upright plate 3222, and a second door moving component 3223. The first door moving component 3221 is fixedly installed, and the door upright plate 3222 is connected to both the first door moving component 3221 and the second door moving component 3223. The second door moving component 3223 is connected to the door body 321. This structure ensures a complete seal between the door body 321 and the opening 312, guaranteeing the vacuum in the vacuum chamber 311, providing a good environment for bonding after adhesive application, and ensuring bonding quality. The first door moving component 3221 and the second door moving component 3223 can be configured according to actual needs, as long as the corresponding components are positioned relatively closer to or further away from the vacuum chamber 31. Preferably, the first door moving component 3221 is configured as a combination of a motor and a lead screw, thereby enabling the other components to move relatively closer to or relatively farther away from the vacuum chamber 31; and by setting a guide rail, it can both guide the movement and improve the stability of the structure. Preferably, the second door moving component 3223 is configured as a moving cylinder 32231, which is fixedly mounted on the door upright plate 3222, and its piston rod is connected to the door body 321; at the same time, the door upright plate 3222 and the door body 321 are provided with moving guide rods 32232, which can both guide the movement of the door body 321 relative to the door upright plate 3222 and improve the stability of the structure; in addition, the two door moving components also form a range-extending structure, improving space utilization. Preferably, both the door upright plate 3222 and the vacuum chamber 311 are provided with door buffer components 324 to provide buffering for the door body 321 during displacement sealing, ensuring that the door body 321 will not make hard contact with the door upright plate 3222 and the vacuum chamber 31, thus ensuring service life.

[0042] Specifically, when sealing and vacuuming are required, the first door moving component 3221 drives the door upright plate 3222 and other components to move closer to the vacuum chamber 31. Once the position is reached, the first door moving component 3221 stops, and simultaneously, the second door moving component 3223 drives the door body 321 to move closer to the vacuum chamber 31, thus achieving a seal between the door body 321 and the chamber opening 312. When only one moving component drives the opening and closing of the door, due to structural characteristics, it is difficult to balance space utilization and the sealing of the vacuum chamber 311. To ensure space utilization, the upper part of the door body 321 cannot always fully contact the vacuum chamber 31, making it difficult to guarantee the seal of the vacuum chamber 311. With only one moving component, to ensure full contact with the door body 321, the moving component needs to be large, making it difficult to balance space utilization. This structure, by setting a second door moving component 3223 and cooperating with the door upright plate 3222, ensures that the door body 321 fully abuts against the vacuum chamber 31, which can guarantee the sealing performance and thus the fitting quality, while also taking into account the space utilization rate.

[0043] Furthermore, refer to Figure 7 and Figure 8As shown, in some embodiments of the vacuum bonding equipment of the present invention, the door moving assembly 322 further includes a blocking component 325. The blocking component 325 includes a blocking cylinder 3251, a blocking guide rod 3252, and a blocking guide sleeve 3253. The blocking cylinder 3251 is fixedly installed, the blocking guide rod 3252 is connected to the driving end of the blocking cylinder 3251, and the blocking guide sleeve 3253 is connected to the door upright plate 3222. By providing the blocking component 325, the reaction force generated by the door upright plate 3222 on the first door moving assembly 3221 when the second door moving assembly 3223 abuts against the door body 321 can be reduced, thereby ensuring the service life of each component. Although the second door moving component 3223 effectively ensures a tight seal between the door body 321 and the opening 312, it generates a significant reaction force when it comes into contact with the door body 321. This reaction force can damage the first door moving component 3221, which is the primary driving force for the door body 321's movement. Repairing or replacing the first door moving component 3221 would incur unnecessary costs and time. Therefore, by installing a blocking component 325, the force exerted by the door upright 3222 on the first door moving component 3221 is transferred to the blocking component 325. This way, even if the blocking component 325 is damaged, only the corresponding blocking component 325 needs to be replaced, saving costs and ensuring the service life of other components. When the first door moving component 3221 moves into position, the blocking cylinder 3251 drives the blocking guide rod 3252 to abut against the blocking guide sleeve 3253, thus limiting the door upright plate 3222; the second door moving component 3223 drives the door body 321 to seal the door opening 312. In this way, the reaction force generated by the second door moving component 3223 driving the door body 321 will be applied to the blocking component 325, rather than to the first door moving component 3221, thus ensuring service life.

[0044] Reference Figure 9 and Figure 10As shown, in some embodiments, the vacuum bonding equipment of the present invention further includes a bonding image acquisition device 40, which is disposed above the vacuum chamber 31. The bonding image acquisition device 40 is used for positioning detection before and after bonding of the lower dial 10 and the inner liner 20. Preferably, the bonding image acquisition device 40 is a CCD camera (CCD is an abbreviation for charge coupled device). The bonding image acquisition device 40 is prior art, and its working principle will not be described in detail. A viewing window 314 adapted to the bonding image acquisition device 40 is provided on the vacuum chamber 31. The setting of the viewing window 314 avoids the bonding image acquisition device 40 from being placed inside the vacuum cavity 311, thereby improving the space utilization rate inside the vacuum cavity 311 and avoiding damage to it from the vacuum environment. An alignment platform 36 is provided between the lower dial fixing fixture 341 and the fixing drive component 342. By setting the bonding image acquisition device 40 through the viewing window 314, the entire bonding process of the lower dial 10 and the inner lining 20 is monitored in real time, and the alignment platform 36 adjusts the position of the lower dial 10 relative to the inner lining 20 in a timely manner, thereby ensuring bonding quality. Specifically, before the ultraviolet curing lamp 33 performs pre-curing, the bonding image acquisition device 40 detects the relative center position of the lower dial 10 and the inner lining 20 through the viewing window 314 and the through hole 3512, and adjusts the relative center position of the lower dial 10 and the inner lining 20 through the alignment platform 36 to ensure accurate pre-curing of the lower dial 10 and the inner lining 20, thus ensuring bonding quality. After the ultraviolet curing lamp 33 has completed full curing, the ultraviolet curing lamp 33 is moved away to avoid obstructing the detection of the bonding image acquisition device 40. The bonding image acquisition device 40 then detects the relative center position of the lower dial 10 and the inner lining 20 through the viewing window 314 to re-check the bonding quality. Preferably, the bonding image acquisition device 40 is connected to the bonding image acquisition driving component 41. The bonding image acquisition driving component 41 adjusts the relative height of the bonding image acquisition device 40, thereby better realizing the detection of the relative center position. Preferably, the alignment platform 36 is set as an XY axis alignment platform 36 to adjust the position of the lower dial 10 in two horizontal directions, thereby realizing the adjustment of the relative center position of the lower dial 10 and the inner lining 20. Preferably, reference... Figure 4As shown, a first light source 3412 providing backlighting for the lower dial 10 and a second light source 3414 providing backlighting for the inner liner 20 are provided below the lower dial fixing fixture 341 to improve detection accuracy. Considering the structure of the lower dial fixing fixture 341, a hollow portion is opened in the fixture plate, and a light-transmitting glass 3413 is provided below it to ensure the backlighting of the first light source 3412. During detection, regardless of whether the second bonding area 21 of the inner liner 20 is facing upwards or downwards, the presence of the through hole 3512 allows the bonding image acquisition device 40 to perform detection.

[0045] Reference Figure 9 and Figure 10 As shown, in some embodiments of the vacuum bonding equipment of the present invention, a laser detection device 50 is further included. The laser detection device 50 is disposed above the vacuum chamber 31 and is used for detection before and after the lower dial 10 and the inner liner 20 are bonded. A height adjustment platform 37 is provided between the lower dial fixing fixture 341 and the fixing drive component 342. Preferably, the laser detection device 50 is connected to the laser detection drive component 51, which is used to drive the laser detection device 50 to move above the corresponding lower dial 10 and inner liner 20 and to detect them. Through this structure, the height adjustment platform 37 and the fixing lifting component 353 of the second fixing component 35 can be effectively linked to adjust the distance between the lower dial 10 and the inner liner 20, controlling the glue filling distance within the range of 0.5±0.05mm to ensure the quality of the glue bonding. Before dispensing, the laser detection device 50 detects the thickness of the lower dial 10 and the inner liner 20, as well as the distance between them. Since both the lower dial 10 and the inner liner 20 are made of transparent glass, taking the inner liner 20 as an example, the laser detection device 50 emits light to illuminate the inner liner 20, and the two surfaces of the inner liner 20 reflect the light at different times; the thickness is detected by measuring this time difference. The height adjustment platform 37 adjusts the level of the lower dial 10 to ensure that the normal of the first bonding area 11 and the normal of the second bonding area 21 are parallel, thus ensuring uniform bonding. After obtaining the data on the thickness and distance, the amount of adhesive dispensed during dispensing and the height to which the second fixed lifting component 353 drives the inner liner 20 to descend can be controlled, further ensuring bonding quality. After the ultraviolet curing lamp 33 has completed curing, the laser inspection device 50 inspects the gap between the lower dial 10 and the inner lining 20 after they have been bonded. By inspecting again, the quality of the adhesive bonding is ensured and defective products are screened out.

[0046] Reference Figure 9 and Figure 11As shown, the vacuum bonding equipment of the present invention, in some embodiments, further includes a feeding device 60 and a picking device 70. The picking device 70 is used for picking and transporting the lower dial 10 and inner liner 20 before adhesive application, and for unloading and transporting them after bonding is completed. The picking device 70 can be configured according to actual needs, such as a robotic arm working with grippers. Preferably, the picking device 70 is configured as a combination of a robotic arm and an electric gripper, capable of gripping different models of lower dial 10 and inner liner 20 without touching the two bonding areas, and gripping from both sides to ensure bonding quality. The feeding device 60 includes a first tray 61 for accommodating the lower dial 10 and a second tray 62 for accommodating the inner lining 20. Both the first tray 61 and the second tray 62 are provided with multiple material positions 63, and each material position 63 is provided with a feeding clearance space 631 for the feeding device 70 to pick up the material. When the lower dial 10 and the inner lining 20 are located at a material position 63, the first bonding area 11 and the second bonding area 21 are both vertically upwards. This structure, by providing the feeding clearance space 631, prevents the feeding device 70 from touching the two bonding areas during material handling, ensuring bonding quality. The vertical upward orientation of the first bonding area 11 and the second bonding area 21 also prevents the two bonding areas from contacting external structures and affecting the dispensing bonding quality.

[0047] Furthermore, in some embodiments of the vacuum bonding equipment of the present invention, the feeding device 60 includes a feeding bracket 64, a material plate driving component 65, a first material tray carrier 66, and a second material tray carrier 67. The feeding bracket 64 is fixedly installed to support the other components. The first material tray carrier 66 and the second material tray carrier 67 are sequentially arranged on the feeding bracket 64 along the height direction and are respectively connected to the material plate driving component 65. The material plate driving component 65 is used to drive the first material tray carrier 66 and the second material tray carrier 67 to move horizontally along the feeding bracket 64. The material plate driving component 65 can be configured according to different needs, such as a combination of a cylinder, a motor, and a lead screw, etc., which will not be described in detail here. The first material tray carrier 66 and the second material tray carrier 67 are each provided with a first material tray 61 and a second material tray 62. This structure enables continuous feeding of the inner liner 20 and the lower dial 10 without stopping the machine. After the inner liner 20 and the lower dial 10 are transported by the first material tray carrier 66, the material tray drive component 65 drives the first material tray carrier 66 to move and replenish the material. Meanwhile, the second material tray carrier 67 can continue to provide materials to the material handling device 70, thereby improving the efficiency of the entire process.

[0048] Furthermore, in some embodiments, the vacuum bonding equipment of the present invention further includes a loading image acquisition device 68, which is connected to the loading device 60. The loading image acquisition device 68 is used for detection during the loading of the lower dial 10 and the inner liner 20. By setting the loading image acquisition device 68, the lower dial 10 and the inner liner 20 can be effectively positioned during the loading process, thereby ensuring that they can be better positioned in the corresponding fixtures for the corresponding processes, and ensuring the quality of adhesive bonding.

[0049] Reference Figure 9 and Figure 12 As shown, in some embodiments of the vacuum bonding equipment of the present invention, a cleaning device 80 is further included. The cleaning device 80 includes a cleaning drive component 81 and a cleaning assembly 82. The cleaning assembly 82 is fixedly disposed. The cleaning drive component 81 is used to transport the lower dial 10 and the inner liner 20 to the cleaning assembly 82 and to clean the first bonding area 11 and the second bonding area 21 before loading materials. Preferably, the cleaning drive component 81 is provided with a cleaning fixing fixture, which is used to fix the lower dial 10 and the inner liner 20 during the process of transporting them to the cleaning assembly 82 for cleaning. The cleaning fixing fixture has a cleaning clearance space 811 to prevent the material handling device 70 from touching the two bonding areas during the handling process, thus ensuring the bonding quality. The cleaning component 82 includes an ultrasonic component 821 and an air extraction component 822. The ultrasonic component 821 emits ultrasonic waves to vibrate dust and other particles in the two bonding areas, while the air extraction components 822 on both sides extract and remove the dust and other particles to avoid secondary pollution. This effectively cleans the lower dial 10 and the inner lining 20 and ensures bonding quality.

[0050] Reference Figure 9 and Figure 13As shown, in some embodiments of the vacuum bonding equipment of the present invention, a dispensing device 90 is further included. The dispensing device 90 includes a dispensing drive component 91, a dispensing image acquisition component 92, and a dispensing component 93. The dispensing drive component 91 is fixedly installed. The dispensing image acquisition component 92 and the dispensing component 93 are both connected to the dispensing drive component 91. The dispensing drive component 91 drives the dispensing image acquisition component 92 and the dispensing component 93. Preferably, the dispensing drive component 91 is a three-axis drive component to achieve displacement in two horizontal directions and in the height direction. The dispensing image acquisition component 92 is used for positioning before dispensing to ensure accurate dispensing and thus guarantee the final dispensing and bonding quality. The dispensing component 93 is prior art and is used for dispensing, so it will not be described in detail. Specifically, before dispensing, the dispensing drive component 91 drives the dispensing image acquisition component 92 to be positioned above the lower dial 10, and then the dispensing component 93 performs the dispensing. Preferably, during dispensing, the adhesive is applied in a zigzag, a zigzag, or an x-shaped trajectory formed by a combination of an inverted c and a regular c, to ensure that the adhesive can fully and evenly cover the required area in a vacuum environment, thus guaranteeing bonding quality. Preferably, the system also includes an adhesive wiping device for cleaning the dispensing assembly 93.

[0051] The working principle of the vacuum bonding equipment described in this invention is as follows:

[0052] The material handling device 70 picks up materials from the feeding device 60. After being detected by the feeding image acquisition device 68, it transports the lower dial 10 and the inner liner 20 to the cleaning device 80, where the cleaning component 82 cleans the two mating areas. After cleaning, the material handling device 70 transports the lower dial 10 and the inner liner 20 to the lower dial fixing fixture 341 and the inner liner fixing fixture 351, respectively. The laser detection device 50 measures the thickness of the lower dial 10 and the inner liner 20, as well as the distance between them, and adjusts the level of the lower dial 10 using the height adjustment platform 37 to ensure that it is parallel to the normal of the inner liner 20. After completion, the glue dispensing device 90 applies glue. Subsequently, with the cooperation of the first door moving component 3221, the second door moving component 3223, and the blocking component 325, the door body 321 and the box opening 312 are sealed, and the vacuum chamber 311 is evacuated. Within the vacuum chamber 311, the fixed drive component 342 drives the lower dial fixing fixture 341 to move directly below the inner liner fixing fixture 351. The relative center positions of the lower dial 10 and the inner liner 20 are detected and adjusted by the bonding image acquisition device 40 and the alignment platform 36. After adjustment, the inner liner 20 and the lower dial 10 are bonded together with the cooperation of the fixed rotation component 352 and the fixed lifting component 353. The ultraviolet curing lamp 33, driven by the curing lamp drive component 331, moves to directly above the inner liner fixing fixture 351. Ultraviolet light passes through the through hole 3512 and pre-cures the inner liner 20 and the lower dial 10. After pre-curing, the inner liner 20 and the lower dial 10 are initially fixed together. At this point, the force of the inner liner fixing fixture 351 is removed, and the pre-cured inner liner 20 and lower dial 10, as well as the ultraviolet curing lamp 33, are moved by the fixing drive component 342 and the curing lamp drive component 331, respectively. This allows the ultraviolet curing lamp 33 to completely irradiate the inner liner 20 and lower dial 10 without being blocked by the inner liner fixing fixture 351, thereby achieving full curing of the inner liner 20 and lower dial 10 and ensuring a firm bond between them. After bonding is completed, the vacuum is broken and the vacuum chamber door 32 is opened. Subsequently, the thickness of the bonded product is checked again by the laser detection device 50, and then the material is unloaded.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
