[0040] The soft-to-hard bonding device suitable for the OCA bonding machine of the present invention belongs to a step in the bonding process of the OCA bonding machine. Specifically, the wearable display module is automatically and accurately fed to the designated position by the LCM automatic feeding unit, and then the silicone glue is accurately applied to the wearable display module in the glue dispensing unit, and then the dried product is transferred to the soft-to-hard bonding unit to bond the wearable display module with the OCA optical glue to obtain the wearable display module / OCA optical glue, and then it is hard-to-hard bonded with the wearable glass cover plate cleaned by the CG automatic feeding unit and the film tearing and cleaning unit to obtain the display module / OCA optical glue / glass cover plate bonding product; finally, the AOI precision detection unit is used to detect the accuracy of the obtained bonding product. Specifically, the soft-to-hard bonding unit completes the entire process flow through the soft-to-hard bonding equipment in the present invention, and the approximate process flow of the soft-to-hard bonding unit is: after tearing off the protective film on the bonding surface of the wearable display module, the semi-finished product delivered by the upstream dispensing unit - the dispensing and drying wearable display module, is bonded with the OCA optical adhesive with the light release film torn off by steel belt bonding, and the finished product after bonding is automatically unloaded to the downstream hard-to-hard bonding unit.

[0041] like Figures 1 to 11 The soft-to-hard bonding device of the present invention, which is suitable for an OCA bonding machine, comprises a flip loading unit 1 for loading a first material, a material taking unit 2 for transferring a second material, a bonding unit 3 for bonding the first material and the second material, and a finished product unloading unit 4 for unloading finished products, which is arranged on one side of the bonding unit 3. Here, the soft in the soft-to-hard bonding device refers to soft materials such as OCA optical glue, and the hard refers to hard materials such as wearable display modules after glue spotting and drying. The device bonds the soft material to the hard material, so it is a soft-to-hard bonding device.

[0042] Among them, Figures 7 to 10As shown, the laminating unit 3 includes a first laminating mechanism 30 arranged on one side of the flip loading unit 1 and cooperating with the flip loading unit 1, a protective film tearing mechanism 31 cooperating with the first laminating mechanism 30 for tearing off the protective film of the first material, a second laminating mechanism 32 arranged opposite to the first laminating mechanism 30 and cooperating with the material taking unit 2, and a light release film tearing mechanism 33 cooperating with the second laminating mechanism 32 for tearing off the light release film on the second material; the protective film tearing mechanism 31 is arranged beside the first laminating mechanism 30, and the light release film tearing mechanism 33 is arranged beside the second laminating mechanism 32. Here, the specific position of the side is not limited, as long as it can ensure that the protective film tearing mechanism 31 and the first laminating mechanism 30, and the light release film tearing mechanism 33 and the second laminating mechanism 32 can better cooperate with each other. Here, the first material is a wearable display module after glue spotting and sun drying, and the second material is OCA optical glue. Specifically, the first laminating mechanism 30 carries the first material, and cooperates with the protective film tearing mechanism 31 to tear off the protective film on the first material; the second laminating mechanism 32 carries the second material, and cooperates with the light release film tearing mechanism 33 to tear off the light release film on the second material; and then, through the cooperation between the first laminating mechanism 30 and the second laminating mechanism 32, the second material after the light release film is torn off is pasted on the first material after the protective film is torn off. The present invention does not specifically limit the number of the first laminating mechanism 30, the protective film tearing mechanism 31, the second laminating mechanism 32, and the light release film tearing mechanism 33. For example, in this embodiment: the laminating unit 3 adopts a symmetrical layout, that is, the first laminating mechanism 30, the protective film tearing mechanism 31, the second laminating mechanism 32, and the light release film tearing mechanism 33 are each provided with two, such as Figure 1 As shown, during operation, the mechanisms on both sides can operate simultaneously, or one side can operate alone, thereby improving work efficiency.

[0043] It should be noted that the bonding unit 3 may also include a positioning photography visual mechanism and a bonding visual correction mechanism for visual alignment compensation; the positioning photography visual mechanism includes a camera, a lens, a light source, an industrial computer, and a visual alignment software to achieve light source lighting, and obtain the real-time position of the first material in the first bonding mechanism 30 under the camera's large field of view imaging, and then feed back the displacement value to be compensated to the X, Y, and Z axes involved in the alignment and bonding operation through the visual software algorithm (the X, Y, and Z axis directions are referenced Figure 1The coordinates in the image are used to realize precise alignment and lamination, and the first laminating mechanism 30 carries the first material to the laminating position to wait for lamination with the second material. The laminating visual correction mechanism also includes a camera, a lens, a light source, an industrial computer, and visual alignment software. The real-time position of the second material in the second laminating mechanism 32 is obtained by imaging with a large field of view of the camera, and then the displacement value to be compensated is fed back to the X, Y, and Z axes involved in the alignment and laminating operation through the visual software algorithm, and the second laminating mechanism 32 carries the second material to the laminating position to wait for lamination with the first material. The laminating unit 3 is provided with an alignment photography visual mechanism and a laminating visual correction mechanism, which is conducive to achieving precise lamination and improving positioning accuracy through visual alignment compensation.

[0044] The soft-to-hard bonding device of the present invention is suitable for an OCA bonding machine, and the general working process is as follows: first, the flip loading unit 1 delivers the first material from the upstream dispensing unit to the first bonding mechanism 30 of the bonding unit 3, and at the same time, the material taking unit 2 loads the second material to the second bonding mechanism 32 of the bonding unit 3. Then, the first bonding mechanism 30 carries the first material and moves to a position opposite to the protective film tearing mechanism 31, and under the coordinated operation of the protective film tearing mechanism 31 and the first bonding mechanism 30, the protective film on the bonding surface of the corresponding first material is torn off; at the same time, the second bonding mechanism 32 carries the second material and moves to a position opposite to the light release film tearing mechanism 33, and under the coordinated operation of the light release film tearing mechanism 33 and the second bonding mechanism 32, the light release film on the corresponding second material is torn off. Then, the first laminating mechanism 30 continues to move with the first material after the protective film is torn off, and the second laminating mechanism 32 continues to move with the second material after the light release film is torn off, until the first laminating mechanism 30 is opposite to the second laminating mechanism 32, so as to realize the laminating operation of the first material and the second material; after the laminating operation is completed, the second laminating mechanism 32 is reset to the initial position, waiting for the next laminating operation, and the finished product after laminating is stored in the second laminating mechanism 32. Finally, the second laminating mechanism 32 continues to carry the finished product to the finished product unloading unit 4, and the finished product unloading unit 4 realizes the unloading of the product, and the finished product is transferred to the downstream hard-to-hard laminating unit to continue the subsequent operation. The equipment includes a flip loading unit 1, a material taking unit 2, a laminating unit 3, and a finished product unloading unit 4. Through the cooperation of each part, the manual loading, unloading, and laminating methods are replaced, and the loading and unloading process and the laminating process are realized. The automated production can greatly improve the production efficiency, reduce the labor intensity of workers, meet the requirements of factory batch production, and have a broad market space. In addition, a visual positioning unit is added to the equipment, which uses a wide field of view to visually locate the position of material products, so that the materials can be automatically and accurately moved to the designated position, further improving the positioning accuracy.

[0045] Further, such as Figure 7As shown, in some specific embodiments of the present invention, the first bonding mechanism 30 includes a first Y-axis moving component 301, a first Z-axis moving component 302 installed on the sliding table of the first Y-axis moving component 301, and a first vacuum adsorption platform 303 installed on the first Z-axis moving component 302. Specifically, the first vacuum adsorption platform 303 is installed on the sliding table of the first Z-axis moving component 302; when working, the first vacuum adsorption platform 303 is used to carry materials, and the first material is placed in the first vacuum adsorption platform 302 accordingly. The first Y-axis moving component 301 and the first Z-axis moving component 302 form a cross slide structure, which can drive the first vacuum adsorption platform 303 to move along the Y-axis and Z-axis directions, so as to realize the precise movement of the first vacuum adsorption platform 303 and facilitate precise material collection. It should be noted that the specific structure of the first Y-axis moving component 301 and the first Z-axis moving component 302 is not limited in the present invention. A belt linear module, a screw linear module, or a cylinder-driven slide structure can be used. There is no specific limitation in the present invention, and technical personnel in this field can choose according to actual needs.

[0046] Further, such as Figure 8As shown, in some specific embodiments of the present invention, the protective film tearing mechanism 31 includes a second X-axis moving component 311, a second Z-axis moving component 312 installed on the second X-axis moving component 311, and a first film removal component 313 installed on the second Z-axis moving component 312; the first film removal component 313 cooperates with the first bonding mechanism 30 to tear off the protective film of the first material. When working, the second X-axis moving component 311 and the second Z-axis moving component 312 form a cross slide structure, which can drive the first film removal component 313 to slide along the X-axis and Z-axis to achieve docking with the first bonding mechanism 30, and cooperate with the first bonding mechanism 30 to tear off the protective film on the first material. Similarly, the specific structure of the second X-axis moving component 311 and the second Z-axis moving component 312 is not limited in the present invention. A belt linear module or a lead screw linear module can be used. The present invention does not make specific limitations, and the technicians in this field can choose according to actual needs. The same is true for other moving components later, which will not be repeated in the present invention. Specifically, the first film removal component 313 is used to tear off the protective film on the first material. The first film removal component 313 includes a rotary film tearing structure installed on the sliding table of the second Z-axis moving component 312, and an easy-to-tear sticker feeding structure located below the rotary film tearing structure and cooperating with the rotary film tearing structure. The rotary film tearing structure can be composed of components such as a cylinder to achieve angle adjustment of the rotary film tearing structure, which is conducive to the coordinated operation with the easy-to-tear sticker feeding structure. When in use, the easy-tear sticker feeding structure is used to feed the easy-tear sticker, and through the second X-axis moving component 311, the second Z-axis moving component 312, and the rotary film-tearing structure, the easy-tear sticker clamping piece in the rotary film-tearing structure is adjusted to a suitable angle, and the easy-tear sticker provided by the easy-tear sticker feeding structure is pasted by the easy-tear sticker clamping piece in the rotary film-tearing structure, and then moved to the position corresponding to the first vacuum adsorption platform 303 carrying the first material, and the protective film on the corresponding first material is torn off; and the easy-tear sticker with the protective film is transported to the waste box of the easy-tear sticker feeding structure, thereby realizing the tearing off of the protective film on the first material. Of course, the first film removal component 313 in the present invention can also be replaced by other structures, as long as it can realize the tearing off of the protective film on the first material, and the present invention does not make specific limitations.

When working, the roller laminating component 323 carries the second material, and by driving the third X-axis moving component 321 to move linearly along the X-axis, the laminating rotating platform 322 rotates, thereby realizing the precise feeding operation of the second material. Specifically, the roller laminating assembly 323 includes a laminating bracket installed on the laminating rotating table 322, a steel belt installed on the top of the laminating bracket for placing the second material, a mobile platform installed on the laminating bracket for realizing the movement of the second material, a laminating lifting member installed on the mobile platform, and a pressing roller member installed at the lifting end of the laminating lifting member. At the same time, the mobile platform, the laminating lifting member, and the pressing roller member are all located below the steel belt; when working, the second material is placed on the corresponding steel belt, and the lifting and lowering of the laminating lifting member are driven to realize the lifting of the second material, which is conducive to laminating and installing the second material on the first material; the mobile platform is driven to drive the pressing roller member to slide, thereby realizing the rolling pressing operation, and laminating the first material and the second material together by laminating the steel belt. Of course, the rolling laminating assembly 323 can also adopt other structural designs, as long as it can realize the laminating and installing of the second material on the first material, and the present invention does not make specific restrictions.

When in use, the fourth Y-axis moving component 331 and the fourth Z-axis moving component 332 form a cross sliding table structure, driving the second film removal component 333 to move to a suitable position to wait for the film tearing operation; the second film removal component 333 and the second bonding mechanism 32 structure work together to tear off the light release film on the second material. The second film removal component 333 in the present invention can adopt the same structural design as the first film removal component 313, or other structural designs, as long as it can achieve the tearing of the light release film on the second material, and no specific design is made in the present invention.

The flip loading mechanism 10 includes a fifth Y-axis moving component 101, a loading flip component 102 installed on the fifth Y-axis moving component 101, and a second vacuum adsorption platform 103 installed on the loading flip component 102 for placing the first material. The transfer platform mechanism 11 includes a sixth X-axis moving component 111, a transfer rotation component 112 installed on the sixth X-axis moving component 111, and a third vacuum adsorption platform 113 installed on the transfer rotation component 112 for placing the first material. During operation, the first material supplied by the upstream unit is placed on the second vacuum adsorption platform 103, and the first material is slid and flipped along the Y axis through the fifth Y-axis moving component 101 and the feeding flip component 102, so as to realize flipping and feeding, and the material is transferred to the first bonding mechanism 30 of the bonding unit 3 accordingly. The feeding flip component 102 drives the second vacuum adsorption platform 103 to perform a flipping operation to realize the flipping operation of the material. The specific structure of the feeding flip component 102 is limited in the present invention. For example, in this embodiment, a cylinder is used to drive the rotating shaft to rotate, and the second vacuum adsorption platform 103 is installed on the rotating shaft accordingly. Of course, the feeding flip component 102 can also adopt other structures, and the present invention does not make any limitation.

[0050] It should be noted that the flip loading unit 1 may also include a first loading visual correction mechanism for visual alignment compensation, which includes a camera, a lens, a light source, an industrial computer, and visual alignment software, to achieve light source lighting, and obtain the real-time position of the first material in the third vacuum adsorption platform 113 through the camera's wide field of view imaging, and then feed back the displacement value that needs to be compensated to the first bonding mechanism 30 involved in the alignment through the visual software algorithm, and the first bonding mechanism 30 accurately obtains the first material in the third vacuum adsorption platform 113, and then performs subsequent operations. The first loading visual correction mechanism is added to the flip loading unit 1, and visual alignment compensation is used to facilitate accurate loading.

[0051] Further, such as Figure 1 , 2, 3 and 5, in some specific embodiments of the present invention, the material taking unit 2 includes a feeding mechanism 20 for providing a second material, and a material taking mechanism 21 arranged beside the feeding mechanism 20 and cooperating with the feeding mechanism 20.

[0052] It should be noted that the material picking unit 2 may also include a second material loading visual correction mechanism for visual alignment compensation, which includes a camera, a lens, a light source, an industrial computer, and visual alignment software. By cooperating with the backlight source on the fourth vacuum adsorption platform 213, the light source is illuminated, and the real-time position of the second material in the fourth vacuum adsorption platform 213 is obtained through the camera's wide field of view imaging, and then the displacement value to be compensated is fed back to the second bonding mechanism 32 involved in the alignment through the visual software algorithm, and the second bonding mechanism 32 accurately obtains the second material in the fourth vacuum adsorption platform 213, and then performs subsequent operations. The second material loading visual correction mechanism is added to the material picking unit 2, and visual alignment compensation is used to facilitate accurate material loading.

[0053] Further, such as Fig.11As shown, in some specific embodiments of the present invention, the finished product unloading unit 4 includes an unloading transfer mechanism 40 matched with the first laminating mechanism 30, and a finished product unloading mechanism 41 installed on one side of the unloading transfer mechanism 40. The unloading transfer mechanism 40 moves the finished product material on the first laminating mechanism 30 to the unloading transfer mechanism 40, and the unloading operation of the finished product is realized through the finished product unloading mechanism 41. Among them, the unloading transfer mechanism 40 includes a ninth X-axis moving component 401, and a fifth vacuum adsorption platform 402 for storing finished product materials installed on the ninth X-axis moving component 401. The ninth X-axis moving component 401 can drive the fifth vacuum adsorption platform 402 to move along the X-axis, move to the bottom of the first laminating mechanism 30, and transfer the finished product material. The finished product unloading mechanism 41 includes a tenth Y-axis moving component 411, a tenth Z-axis moving component 412 installed on the tenth Y-axis moving component 411, a unloading and flipping component 413 installed on the tenth Z-axis moving component 412 for realizing material flipping, and a sixth vacuum adsorption platform 414 installed on the unloading and flipping component 413. The tenth Y-axis moving component 411 and the tenth Z-axis moving component 412 form a cross slide, which controls the sixth vacuum adsorption platform 414 to move to an appropriate position, and realizes the flipping operation of the sixth vacuum adsorption platform 414 through the unloading and flipping component 413, thereby realizing the flipping of the finished material, and transporting the finished material to a position relative to the downstream hard-to-hard bonding unit to realize the unloading of the finished material. Similarly, the specific structure of the unloading and flipping component 413 in the present invention is not limited. For example, in this embodiment, a cylinder + flipping axis form is adopted to realize the flipping of the unloading and flipping component 413, and other forms can also be adopted. There is no limitation in the present invention, as long as the flipping operation can be realized.

[0054] Furthermore, the soft-to-hard bonding device may also include a central control unit, which is respectively connected to the flip loading unit 1, the material taking unit 2, the bonding unit 3, and the finished product unloading unit 4 to achieve automatic control of the device.

[0055] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in the field after reading this specification are all within the scope of protection of the present invention.
