In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0042] The embodiment provides a laminating device, which comprises a first carrier plate 101, a second carrier plate 102, a driving device (not shown in the figure) and a parallelism adjusting device, the first carrier plate 101 can fix a product body, the second carrier plate 102 can fix a product cover plate, the driving device is connected with the parallelism adjusting device, and the driving device is used for driving the parallelism adjusting device and the first carrier plate 101 to be close to or away from the second carrier plate 102. During operation, the driving device first separates the first carrier plate 101 from the second carrier plate 102, leaves enough operation space, facilitates an operator to take out the laminated product body and product cover plate, and fixes the non-laminated product body and product cover plate on the corresponding first carrier plate 101 and second carrier plate 102 respectively. After the product body and the product cover plate are placed, the driving device drives the first carrier plate 101 to be close to the second carrier plate 102, and stops when the product cover plate and the body are about to be laminated. Then, the parallelism adjusting device accurately adjusts the parallelism of the first carrier plate 101, ensures that the product body and the product cover plate are closely and flatly laminated, and guarantees the laminating quality. Through the above-mentioned cyclic operation, efficient product lamination is realized.

[0043] Specifically, the first carrier plate 101 and the second carrier plate 102 adopt an adsorption mode to fix the product body and the product cover plate. The adsorption fixing mode enhances the stability of the product body and the product cover plate during lamination, reduces the lamination error caused by external interference, and further improves the lamination precision and product quality. In other embodiments, the first carrier plate 101 can also fix the product cover plate, and the second carrier plate 102 can also fix the product body.

[0044] It is worth noting that the driving device belongs to the prior art known in the art, and therefore the specific structure thereof will not be described here.

[0045] As shown in FIG. 1, Figures 1-6 The parallelism adjusting device can adjust the parallelism of the first carrier plate 101 and the second carrier plate 102, the parallelism adjusting device is connected with the side of the first carrier plate 101 away from the second carrier plate 102, the parallelism adjusting device comprises a mounting seat 1, three angle self-adapting mechanisms and three lifting mechanisms 3, the mounting seat 1 can be arranged in a spaced manner with the first carrier plate 101; the three angle self-adapting mechanisms are connected with the first carrier plate 101 and arranged in a triangular shape; the three lifting mechanisms 3 are connected with the mounting seat 1, the number and positions of the lifting mechanisms 3 and the angle self-adapting mechanisms are one-to-one corresponding, the angle self-adapting mechanisms are connected with the output ends of the lifting mechanisms 3, and the lifting mechanisms 3 are used for driving the angle self-adapting mechanisms to move along the arrangement direction of the first carrier plate 101 and the second carrier plate 102, so that the first carrier plate 101 reaches a preset position and is parallel to the second carrier plate 102. The preset position here refers to the lamination position of the product body and the product cover plate.

[0046] The interval of the mounting seat 1 is arranged to provide the non-interference operation space for each angle self-adapting mechanism and the lifting mechanism 3, and ensure the independent work of each mechanism; since the three angle self-adapting mechanisms are arranged in a triangle, the stable geometric structure can provide stable support and angle adjustment basis for the first carrier plate 101. When the lifting mechanism 3 works, the output end drives the corresponding angle self-adapting mechanism to move along the arrangement direction of the first carrier plate 101 and the second carrier plate 102. Since there are three independently adjustable lifting mechanisms 3 and angle self-adapting mechanisms, by controlling the different lifting amounts of different lifting mechanisms 3, the height of the first carrier plate 101 at different positions can be changed, and then the angle of the first carrier plate 101 can be adjusted. Through the overall structure and cooperative working mode, the parallelism adjusting device can realize high-precision parallelism adjustment, solve the problem of low precision in the traditional adjustment mode, and is stable and reliable in operation, avoiding the change of parallelism after adjustment. This makes the first carrier plate 101 and the second carrier plate 102 closely and flatly adhere, effectively reduces the problems of not closely adhering, bubbles, uneven stress, etc., significantly improves the product adhesion quality, reduces the defective rate in mass production, and then reduces the production cost.

[0047] As shown in Figures 1-5 The three angle self-adapting mechanisms are respectively a first angle self-adapting mechanism 21, a second angle self-adapting mechanism 22 and a third angle self-adapting mechanism 23. The first angle self-adapting mechanism 21 comprises a first joint bearing assembly 211 and a first guide assembly 212, the first joint bearing assembly 211 is connected with the first carrier plate 101, and the first guide assembly 212 is arranged between the lifting mechanism 3 and the first joint bearing assembly 211. The first guide assembly 212 is used for moving the first joint bearing assembly 211 relative to the corresponding lifting mechanism 3 along the first direction. The second angle self-adapting mechanism 22 comprises a second joint bearing assembly 221 and a second guide assembly 222, the second joint bearing assembly 221 is connected with the first carrier plate 101, and the second guide assembly 222 is arranged between the lifting mechanism 3 and the second joint bearing assembly 221. The second guide assembly 222 is used for moving the second joint bearing assembly 221 relative to the corresponding lifting mechanism 3 in the plane arranged at an angle with the first direction. The third angle self-adapting mechanism 23 comprises a third joint bearing assembly 231, and the third joint bearing assembly 231 is connected with the first carrier plate 101.

[0048] The device can flexibly adjust the angle of the first carrier plate 101 in multiple directions through the cooperative operation of the three angle adaptive mechanisms, ensuring that it always remains parallel during the fitting process, effectively improving the fitting precision and product quality. During the specific adjustment process, first, adjust the third angle adaptive mechanism 23 to make the force between the first carrier plate 101 and the second carrier plate 102 at this position reach the preset value. Then, adjust the second angle adaptive mechanism 22 and the first angle adaptive mechanism 21 in turn, so that the force between the first carrier plate 101 and the second carrier plate 102 at the corresponding position also reaches the preset value. When the three detection mechanisms 4 detect that the forces are equal, it indicates that the first carrier plate 101 and the second carrier plate 102 have reached a parallel state, and at this time, the fitting force between the product body and the product cover plate meets the fitting quality requirements. During the adjustment process, the first angle adaptive mechanism 21 and the second angle adaptive mechanism 22 are adjusted based on the third angle adaptive mechanism 23, and at the same time, the first guide assembly 212 and the second guide assembly 222 can effectively prevent the occurrence of suffocation.

[0049] Specifically, during adjustment, the first guide assembly 212 guides the first joint bearing assembly 211 connected thereto, allowing it to only move linearly in the first direction, driving the first carrier plate 101 to change its position in this direction to adjust the angle. The second guide assembly 222 is more flexible, allowing the second joint bearing assembly 221 to move in a plane that is arranged at an angle to the first direction. The second joint bearing assembly 221 can move in two directions (the second direction and the third direction) that are at an angle to each other within this plane, driving the first carrier plate 101 to change its position in both directions to precisely adjust the angle. The first direction is perpendicular to the movement direction of the lifting mechanism 3, i.e., perpendicular to the arrangement direction of the first carrier plate 101 and the second carrier plate 102. The angle between this plane and the first direction ranges from 0 to 180 degrees, such as 15 degrees, 30 degrees, 45 degrees, 90 degrees, 120 degrees, 145 degrees, etc. The angle between the second direction and the third direction can be 15 degrees, 30 degrees, 45 degrees, 90 degrees, 120 degrees, 145 degrees, etc. As can be seen, the first direction mainly focuses on providing basic displacement for angle adjustment of the first carrier plate 101 in a single vertical direction, while the cooperative action of the two mutually angled directions (the second direction and the third direction) within the plane of the second guide assembly 222 enriches the dimensions of the adjustment, precisely regulating the angle of the first carrier plate 101 from multiple directions, and together ensuring that the first carrier plate 101 and the second carrier plate 102 always remain parallel during the fitting process, greatly improving the fitting precision and quality of the product.

[0050] As Figure 3As shown, in this embodiment, the first guide component 212 includes a first guide rail 2121 and a first slider 2122. The first slider 2122 is connected to the output end of the lifting mechanism 3, and the first guide rail 2121 is connected to the first joint bearing assembly 211. The first slider 2122 is slidably disposed on the first guide rail 2121 along a first direction. During the angle adjustment of the first platform 101, if the first guide component 212 is not present, when the lifting mechanism 3 drives the first joint bearing assembly 211 and the first platform 101 to move, their movement direction may be uncontrolled, causing the movement trajectories of each component to intersect and interfere with each other. In this case, unreasonable stress concentration will occur between the components, resulting in mutual squeezing and jamming of the components, leading to a jamming phenomenon. The first guide component 212 limits the movement direction of the first joint bearing assembly 211 and the first platform 101 to the first direction, avoiding the component jamming problem caused by chaotic movement trajectories. At the same time, the degree of freedom of movement of the first joint bearing assembly 211, combined with the guiding effect, further reduces the possibility of jamming. This not only ensures smooth operation of the parallelism adjustment device, improving equipment reliability and stability, but also makes angle adjustment more precise. This helps improve the parallelism adjustment accuracy of the first carrier plate 101 and the second carrier plate 102 and the product bonding quality. Furthermore, it reduces abnormal wear of components, lowers the equipment failure rate, extends the service life of the bonding equipment, and reduces maintenance costs. In other embodiments, the first slider 2122 is connected to the first joint bearing assembly 211, and the first guide rail 2121 is connected to the lifting mechanism 3. The first slider 2122 is slidably disposed on the first guide rail 2121 along a first direction.

[0051] like Figure 3 As shown, the first joint bearing assembly 211 includes a first joint bearing 2111, a first connecting rod 2112, and a first connecting seat 2113. The first connecting seat 2113 is connected to the first guide rail 2121. The first joint bearing 2111 is mounted on the first connecting seat 2113. One end of the first connecting rod 2112 is connected to the first joint bearing 2111, and the other end is bolted to the first platform plate 101. When the angle of the first platform plate 101 is adjusted, the first joint bearing 2111 can adapt to small angle changes, avoiding stress concentration and jamming caused by rigid connection, making motion transmission more flexible, ensuring smooth operation of the angle adaptive mechanism, and more accurately controlling the motion trajectory and angle of the first platform plate 101, reducing adjustment errors, and improving the parallelism adjustment accuracy of the first platform plate 101 and the second platform plate 102 and the product bonding quality.

[0052] like Figure 4As shown, the second guide assembly 222 includes a first connecting piece 2221 and a slide rail 2222, the slide rail 2222 is connected with the second joint bearing assembly 221, the first connecting piece 2221 is connected with the lifting mechanism 3, the first connecting piece 2221 is provided with a sliding groove 22211, the distance between the two side walls of the sliding groove 22211 is greater than the distance between the two side walls of the slide rail 2222, and the slide rail 2222 abuts against the bottom wall of the sliding groove 22211. When the lifting mechanism 3 drives the first connecting piece 2221 to move, the movement is transmitted to the second joint bearing assembly 221 and the first carrier plate 101 through the abutment of the slide rail 2222 and the bottom wall of the sliding groove 22211. The movement space provided by the sliding groove 22211 for the slide rail 2222 enables the slide rail 2222 to adaptively move and adjust the angle when the angle is adjusted, avoids being stuck due to slight deviation, and ensures the movement flexibility. At this time, the distance between the two side walls of the sliding groove 22211 is slightly greater than the distance between the two side walls of the slide rail 2222, which allows the slide rail 2222 to adaptively move and adjust the angle, while limiting the slide rail 2222 from appearing a larger displacement deviation; and the abutment of the slide rail 2222 and the bottom wall of the sliding groove 22211 ensures stable transmission of force and provides movement stability. This design combining flexibility and stability enables the second angle adaptive mechanism 22 to have multi-directional adjustment capability, more accurately adjusts the angle of the first carrier plate 101, corrects the angle deviation, ensures that the first carrier plate 101 and the second carrier plate 102 have higher parallelism when they are attached, and further improves the product attachment precision and quality.

[0053] As shown in Figure 4 The second joint bearing assembly 221 includes a second joint bearing 2211, a second connecting seat 2213 and a second connecting seat 2213. The second connecting seat 2213 is connected with the slide rail 2222, the second joint bearing 2211 is installed on the second connecting seat 2213, one end of the second connecting rod 2212 is connected with the second joint bearing 2211, and the other end is bolted with the first carrier plate 101. When the angle of the first carrier plate 101 is adjusted, the second joint bearing 2211 can adapt to slight angle changes, avoid stress concentration and choking phenomenon caused by rigid connection, make movement transmission more flexible, ensure smooth operation of the angle adaptive mechanism, and also can more accurately control the movement trajectory and angle of the first carrier plate 101, reduce adjustment error, and improve the parallelism adjustment precision of the first carrier plate 101 and the second carrier plate 102 and the product attachment quality.

[0054] As shown in Figure 5As shown, the third angle adaptive mechanism 23 comprises a third joint bearing assembly 231, which comprises a third joint bearing 2311 and a third connecting rod 2312. The third joint bearing 2311 is mounted on the lifting mechanism 3, and one end of the third connecting rod 2312 is connected with the third joint bearing 2311, and the other end is bolted with the first stage plate 101. When the first stage plate 101 is adjusted in angle, the third joint bearing 2311 can adapt to the small angle change, avoid stress concentration and death, flexibly transfer the motion, ensure the operation of the angle adaptive mechanism, accurately control the first stage plate 101, and improve the parallelism adjustment precision and product fitting quality.

[0055] As shown in Figures 1-6 The lifting mechanism 3 comprises a fine thread screw 31 and a second connecting piece 32. The second connecting piece 32 is connected with the angle adaptive mechanism, and the fine thread screw 31 is connected with the mounting base 1. The fine thread screw 31 is used to drive the second connecting piece 32 to move along the arrangement direction of the first stage plate 101 and the second stage plate 102. The fine thread screw 31 has small pitch, which makes the displacement change of the second connecting piece 32 small under the same rotation angle, and can finely adjust the position of the first stage plate 101. The fine thread screw 31 has good self-locking property, and can keep the position of the second connecting piece 32 stable after stopping rotation. This makes the movement of the lifting mechanism 3 accurate and controllable, ensures the stability of the first stage plate 101 when it approaches, meets the high-precision fitting requirement, reduces the fitting problem, improves the product fitting quality, reduces the scrap rate, and enhances the controllability and flexibility of operation.

[0056] Specifically, as shown in Figures 3-6 The end of the fine thread screw 31 close to the first stage plate 101 is provided with an adjusting part. The upper surface of the adjusting part is provided with angle scales. Through these angle scales, the operator can more accurately fine-tune the angle of the first stage plate 101. In actual operation, the worker can rotate the fine thread screw 31 according to the specific parallelism requirement and the angle scale, so as to accurately control the position of the first stage plate 101.

[0057] As shown in Figures 3-6As shown, the lifting mechanism 3 also includes a first elastic element 33 and a base 36. The base 36 is connected to the mounting base 1. One end of the first elastic element 33 is connected to the second connecting element 32, and the other end of the first elastic element 33 is connected to the base 36 or the mounting base 1. When the fine-pitch screw 31 drives the second connecting element 32, the equipment is susceptible to vibration and impact. The first elastic element 33 is a tension spring. The first elastic element 33 absorbs and disperses energy through elastic deformation, buffering vibration and impact, and preventing vibration and impact from being directly transmitted to the first platform 101, thus avoiding positional deviation of the first platform 101. Specifically, the number of tension springs can be set to one, two, or three, etc., as long as the tension spring layout can cover the key stress area and the number is adapted to the degree of vibration and impact generated.

[0058] like Figures 1-5 As shown, in this embodiment, the lifting mechanism 3 further includes a third guide component 35, which includes a second guide rail 351 and a second slider 352 that are slidably disposed. The second guide rail 351 is connected to the base 36, and the second slider 352 is connected to the second connecting member 32. When the fine-pitch screw 31 rotates to drive the second connecting member 32 to move, the third guide component 35 constrains its movement, causing the second connecting member 32 to move along the predetermined path of the second guide rail 351 (i.e., along the arrangement direction of the first platform 101 and the second platform 102), accurately converting the rotational motion of the fine-pitch screw 31 into linear motion. This enhances motion stability and provides a guarantee for high-quality product bonding. In other embodiments, the second guide rail 351 is connected to the second connecting member 32, and the second slider 352 is connected to the base 36.

[0059] like Figure 6 As shown, the lifting mechanism 3 also includes a second elastic element 34, and the second connecting member 32 includes a threaded hole 321 arranged along the arrangement direction of the first platform 101 and the second platform 102. A limiting hole 322 is formed on the side wall of the threaded hole 321, and the second elastic element 34 is disposed within the limiting hole 322. One end of the second elastic element 34 abuts against the fine-pitch screw 31, and the other end abuts against the bottom wall of the limiting hole 322. When the fine-pitch screw 31 rotates, driving the second connecting member 32 to move, there may be gaps between the threaded pairs, and external vibrations and impacts can affect transmission stability. The second elastic element 34 applies elastic force to eliminate the effects of gaps, making the fit tighter, and can also absorb and buffer energy through elastic deformation, reducing interference from external factors. This improves transmission accuracy, precisely controls the position of the first platform 101, and improves the bonding quality; enhances transmission stability, making the first platform 101 move smoothly; extends the service life of components and reduces maintenance costs; and ensures the accuracy of the force detection of the fine-pitch screw 31 by the detection mechanism 4, which helps to further improve bonding accuracy.

[0060] Specifically, such as Figure 6As shown, the second elastic member 34 includes a stepped column 341 and a spring 342, one end of the spring 342 is connected to the large-diameter end of the stepped column 341, the other end of the spring 342 abuts against the bottom wall of the limiting hole 322, and the small-diameter end of the stepped column 341 abuts against the fine-threaded screw rod 31. The side wall of the limiting hole 322 is provided with a limiting protrusion, which can prevent the second elastic member 34 from coming out of the limiting hole 322.

[0061] As shown in Figure 1 , Figures 3-5 As shown, the parallelism adjusting device further includes at least three detection mechanisms 4, one-to-one correspondence between the detection mechanisms 4, the lifting mechanism 3 and the angle adaptive mechanism, and the detection mechanisms 4 are used to detect the interaction force between the first carrier plate 101 and the second carrier plate 102 at the position of the corresponding angle adaptive mechanism. The first carrier plate 101, the product body, the product cover plate and the carrier plate 102 abut in turn, and when the first carrier plate 101 and the second carrier plate 102 are parallel, the fitting force (the interaction force between the first carrier plate 101 and the second carrier plate 102) detected by each position detection mechanism 4 is equal in size, and the detection mechanism 4 can feedback the stress condition in the adjustment process in real time, thereby further improving the fitting precision and stability and reducing the rate of defective products caused by uneven stress.

[0062] Specifically, as shown in Figures 3-5 One end of the detection mechanism 4 is connected with the mounting seat 1, and the other end is provided with a bearing seat (not shown in the figure), and the fine-threaded screw rod 31 is connected with the bearing seat. The fine-threaded screw rod 31 serves as a transmission component of the lifting mechanism 3 and can drive the first carrier plate 101 to move in the arrangement direction. During the fitting process, the interaction force between the first carrier plate 101 and the second carrier plate 102 is transmitted to the detection mechanism 4 through the fine-threaded screw rod 31. The detection mechanism 4 can convert the received force into a measurable physical quantity, and by detecting the stress change of the fine-threaded screw rod 31, the distribution of the interaction force between the first carrier plate 101 and the second carrier plate 102 is indirectly reflected, and then the parallelism state of the first carrier plate 101 and the second carrier plate 102 is accurately inferred. This connection mode can accurately feedback the parallelism information and realize real-time dynamic adjustment.

[0063] Specifically, as shown in Figure 1 , Figures 3-5 The detection mechanism 4 includes a pressure sensor 41 and a base 42, the base 42 is connected with the mounting seat 1, and the pressure sensor 41 is installed on the base 42. Through real-time monitoring of the pressure sensor 41, the interaction force between the first carrier plate 101 and the second carrier plate 102 can be accurately controlled, the stability and consistency of the fitting process can be ensured, and the fitting quality can be further improved.

[0064] In an optional embodiment, the two ends of the detection mechanism 4 are connected with the angle self-adapting mechanism and the first carrier plate 101 respectively.
