DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0017] The bonding device provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0018] like Figures 1 to 10 As shown, the embodiment of the present application provides a laminating device, which includes an operating platform 100 and a rolling device 200, a feeder feeding device 300, a vacuum suction device 400 and a carrying table 600 for carrying a product 510 arranged on the operating platform 100. It should be noted that the feeder feeding device 300 is used to convey auxiliary materials 520 (such as protective films, etc.) instead of conveying products 510. Optionally, the auxiliary materials conveyed by the feeder feeding device 300 can be rolled auxiliary materials 520 or sheet-shaped auxiliary materials 520, and the embodiment of the present application does not specifically limit this.

[0019] The operating platform 100 has a material picking position and a bonding position. The vacuum suction device 400 includes a connected rotating drive component 410 and a vacuum mesh plate 420. The rotating drive component 410 can drive the vacuum mesh plate 420 to rotate relative to the operating platform 100, and the vacuum mesh plate 420 can be raised and lowered relative to the operating platform 100. The material picking position and the bonding position are arranged around the rotating drive component 410 and at intervals along the rotation direction of the rotating drive component 410.

[0020] When the vacuum mesh plate 420 is located at the material picking position, the vacuum mesh plate 420 absorbs the auxiliary material 520 pre-peeled by the feeder feeding device 300; when the vacuum mesh plate 420 and the carrier platform 600 are both located at the bonding position, the vacuum mesh plate 420 is located above the carrier platform 600, and the rolling device 200 can be pressed on the vacuum mesh plate 420 and move relative to the vacuum mesh plate 420 to make the auxiliary material 520 bonded to the product 510 carried by the carrier platform 600.

[0021] When the vacuum mesh plate 420 is located at the material picking position, the vacuum mesh plate 420 descends, the vacuum mesh plate 420 absorbs the auxiliary material 520, and then the vacuum mesh plate 420 rises; then, the rotating drive member 410 drives the vacuum mesh plate 420 to rotate to the bonding position, and the vacuum mesh plate 420 descends to approach the supporting platform 600 so that the auxiliary material 520 and the product 510 are almost in contact or there is a gap of about 0.5 mm. When the auxiliary material 520 is bonded to the product 510, the vacuum mesh plate 420 continues to descend a distance of about 0.5 mm, thereby adsorbing the product 510 onto the vacuum mesh plate 420.

[0022] In the embodiment of the present application, the auxiliary material 520 is sucked by the vacuum mesh plate 420. Since the vacuum mesh plate 420 is relatively large, the auxiliary material 520 can be attached to the vacuum mesh plate 420, thereby fixing the auxiliary material 520, which can prevent the auxiliary material 520 from bending; and the rolling and pasting device 200 is pressed on the vacuum mesh plate 420, rolling and pasting at the same time, realizing rolling and pasting in one, which can prevent the auxiliary material 520 from bending during the process of pasting the auxiliary material 520, thereby improving the pasting accuracy of the auxiliary material 520. Therefore, the embodiment of the present application can solve the problem of poor pasting accuracy of the auxiliary material 520 by the current pasting equipment.

[0023] In an optional embodiment, the vacuum screen 420 includes a screen body 421 and a connecting bracket 422 connected to each other. The screen body 421 is connected to the output shaft of the rotating drive member 410 through the connecting bracket 422. The screen body 421 includes a main frame 421a, a sealing plate 421b, a middle frame 421c and a screen 421d stacked in sequence. The main frame 421a is connected to the connecting bracket 422, that is, the main frame 421a is connected to one end of the connecting bracket 422, and the other end of the connecting bracket 422 is connected to the output shaft of the rotating drive member 410. The sealing plate 421b, the middle frame 421c and the screen 421d are stacked in sequence. The plate 421b and the mesh plate 421d are both sealed and connected to the middle frame 421c. The sealing plate 421b, the middle frame 421c and the mesh plate 421d form a cavity. The middle frame 421c is provided with an exhaust port 421c1 connected to the cavity. The cavity here can specifically be a vacuum cavity. The vacuum pump is connected to the exhaust port 421c1 through an air duct. The mesh plate 421d is used to absorb the auxiliary material 520. When the vacuum mesh plate 420 needs to absorb the auxiliary material 520, the vacuum pump absorbs the air in the cavity to form a vacuum, so that the mesh plate 421d absorbs the auxiliary material 520. The sealing plate 421b and the mesh plate 421d are both deformable parts. When the vacuum mesh plate 420 and the supporting platform 600 are both in the bonding position, the rolling device 200 can be pressed on the sealing plate 421b and move relative to the sealing plate 421b. The sealing plate 421b and the mesh plate 421d are both deformed to make the auxiliary material 520 bonded to the product 510.

[0024] Optionally, the thickness of the cavity may be about 5 mm, and of course it may be selected according to actual needs, and no specific limitation is made here.

[0025] After the vacuum mesh plate 420 absorbs the auxiliary material 520 at the material picking position, the rotating driving part 410 drives the vacuum mesh plate 420 to rotate so that the vacuum mesh plate 420 is located at the fitting position. At the same time, the supporting platform 600 moves to the fitting position, and then the rolling device 200 presses on the sealing plate 421b and moves relative to the sealing plate 421b. At this time, the sealing plate 421b is deformed, and further the sealing plate 421b contacts the mesh plate 421d. The rolling device 200 presses the mesh plate 421d through the sealing plate 421b, so that the mesh plate 421d is also deformed, thereby fitting the auxiliary material 520 to the product 510. In this solution, since the mesh plate 421d is a deformable part, during the process of laminating the auxiliary material 520, there is soft contact between the mesh plate 421d and the auxiliary material 520, which can protect the auxiliary material 520 and prevent the auxiliary material 520 from being damaged; and, during the process of laminating the auxiliary material 520, a pressing force is applied to the mesh plate 421d by the rolling device 200, so that the mesh plate 421d is deformed, and the auxiliary material 520 is also subjected to a certain pressing force, which can improve the bonding firmness between the auxiliary material 520 and the product 510.

[0026] Optionally, the mesh body 421 further includes a sealing cover 421e, which is sealingly disposed at the air extraction port 421c1 of the middle frame 421c, and the air guide tube is connected to the air extraction port 421c1 through the sealing cover 421e. The setting of the sealing cover 421e can improve the sealing performance at the air extraction port 421c1. Optionally, the number of the air extraction ports 421c1 is at least two, and the sealing cover 421e and the air guide tube are both disposed in a one-to-one correspondence with the air extraction ports 421c1, thereby improving the efficiency of extracting air in the cavity, and further improving the working efficiency of the vacuum mesh 420 in absorbing the auxiliary material 520.

[0027] Optionally, the tension of the sealing plate 421b is less than the tension with the mesh plate 421d. At this time, the deformation of the sealing plate 421b is larger, so that the sealing plate 421b is pressed against the mesh plate 421d; further optionally, the tension of the sealing plate 421b can be 10~15N, and the tension of the mesh plate 421d can be 25~30N. Of course, it can also be selected according to actual needs, and the embodiment of the present application does not make specific restrictions on this.

[0028] In a further optional embodiment, the sealing plate 421b and the mesh plate 421d both include a mesh and a sealing layer, and the sealing layer is embedded in the mesh holes of the mesh so that the sealing layer and the mesh are arranged on the same layer, and the sealing plate 421b is a fully sealed structure, that is, each area of ​​the mesh of the sealing plate 421b is embedded with a sealing layer; the sealing layer of the mesh plate 421d has an avoidance area, and the mesh plate 421d absorbs the auxiliary material 520 through the avoidance area, and the sealing layer of the mesh plate 421d is only embedded in a partial area of ​​the mesh, such as the edge area of ​​the mesh, thereby forming an avoidance area in the central area of ​​the mesh, and the cavity is connected to the external environment through the mesh holes in the avoidance area. This solution forms a sealing plate 421b and a mesh plate 421d with deformation properties through mesh and a sealing layer. Since the mesh has good elasticity and wrinkle resistance, it is not only convenient to make the sealing plate 421b and the mesh plate 421d, but also more durable. In addition, the mesh has good air permeability, which is conducive to improving the working efficiency of the mesh plate 421d in absorbing the auxiliary material 520, and the auxiliary material 520 has good stability after absorbing the auxiliary material 520. Of course, the mesh plate 421d can also be a rigid structure.

[0029] Optionally, the mesh of the sealing plate 421b can be made of one of polyester, silicone, and rubber, and the embodiment of the present application does not impose any specific restrictions on this; optionally, the mesh of the mesh plate 421d can be made of polyester, which has the characteristics of high elasticity and wear resistance, and of course it can also be made of other materials, and the embodiment of the present application does not impose any specific restrictions on this.

[0030] Optionally, the sealing layer may be made of optical adhesive, and of course may also be made of other materials, which is not specifically limited in the embodiments of the present application.

[0031] In another optional embodiment, the vacuum suction device 400 also includes a rotating bracket 430, and the output shaft of the rotating drive member 410 is connected to the vacuum mesh plate 420 through the rotating bracket 430. Optionally, the number of vacuum mesh plates 420 can be one; or, in other optional embodiments, the number of vacuum mesh plates 420 is at least two, and each vacuum mesh plate 420 is connected to the rotating bracket 430, and each vacuum mesh plate 420 is arranged at intervals around the rotating bracket 430. The rotating drive member 410 can drive each vacuum mesh plate 420 to rotate together through the rotating bracket 430, so that each vacuum mesh plate 420 can cycle between the material picking position and the bonding position in turn. During the laminating process, multiple vacuum mesh plates 420 can work simultaneously, for example, the first vacuum mesh plate 420 is located at the material taking position to absorb the auxiliary material 520, the second vacuum mesh plate 420 is located at the laminating position, the rolling device 200 laminates the auxiliary material 520 onto the product 510, and then the rotating drive member 410 drives each vacuum mesh plate 420 to rotate together through the rotating bracket 430, so that the first vacuum mesh plate 420 rotates to the laminating position, and the auxiliary material 520 is laminated onto the product 510 through the rolling device 200, and the second vacuum mesh plate 420 rotates to the material taking position to absorb the auxiliary material 520, and the cycle is repeated in sequence. This solution sets multiple vacuum mesh plates 420 to work simultaneously, which is conducive to improving the working efficiency of laminating equipment laminating auxiliary materials 520. Optionally, the vacuum suction device 400 further includes a pneumatic slip ring 460 , which is disposed on the rotating bracket 430 , and the pneumatic slip ring 460 is communicated with the cavity of the vacuum mesh plate 420 .

[0032] In a further optional embodiment, each vacuum mesh plate 420 is slidably connected to the rotating bracket 430 along the extension direction of the rotation center axis of the rotating bracket 430. Optionally, one of the outer peripheral surfaces of the vacuum mesh plate 420 and the rotating bracket 430 is provided with a slider 423, and the other is provided with a slide rail. The slider 423 slides with the slide rail to make the vacuum mesh plate 420 slidably connected to the rotating bracket 430.

[0033] The vacuum suction device 400 also includes at least two first lifting drive members 440. Optionally, each first lifting drive member 440 can be arranged on the rotating bracket 430; or, each first lifting drive member 440 is arranged on the operating platform 100. The material picking position and the bonding position are both provided with a first lifting drive member 440. The first lifting drive member 440 located at the material picking position can be connected to the vacuum mesh plate 420 located at the material picking position, and drive the vacuum mesh plate 420 located at the material picking position to rise and fall. The first lifting drive member 440 located at the bonding position can be connected to the vacuum mesh plate 420 located at the bonding position, and drive the vacuum mesh plate 420 located at the bonding position to rise and fall.

[0034] When the vacuum mesh plate 420 is located at the material picking position, the first lifting drive component 440 arranged at the material picking position is connected to the vacuum mesh plate 420, the first lifting drive component 440 drives the vacuum mesh plate 420 to descend, the vacuum mesh plate 420 absorbs the auxiliary material 520, and then the first lifting drive component 440 drives the vacuum mesh plate 420 to rise again; then, the rotary drive component 410 drives the vacuum mesh plate 420 to rotate to the fitting position, the first lifting drive component 440 located at the fitting position is connected to the vacuum mesh plate 420, the first lifting drive component 440 drives the vacuum mesh plate 420 to descend to approach the supporting platform 600, so that the auxiliary material 520 is almost in contact with the product 510 or there is a gap of about 0.5 mm, when the auxiliary material 520 is attached to the product 510, the first lifting drive component 440 continues to drive the vacuum mesh plate 420 to descend a distance of about 0.5 mm, thereby adsorbing the product 510 onto the vacuum mesh plate 420. In this solution, each first lifting driving member 440 is disposed on the operating platform 100 , which can reduce the load of the rotating bracket 430 , thereby saving the driving force output by the rotating driving member 410 .

[0035] Optionally, a support plate 431 is further provided on the outer peripheral surface of the rotating bracket 430, and the vacuum suction device 400 also includes an elastic driving member 450. A mounting groove is provided on the side of the slider 423 facing the support plate 431, and at least a portion of the elastic driving member 450 is arranged in the mounting groove. One end of the elastic driving member 450 abuts against the bottom of the mounting groove, and the other end of the elastic driving member 450 abuts against the support plate 431, thereby improving the stability of the vacuum mesh plate 420 during the lifting process; at the same time, the vacuum mesh plate 420 can be driven to rise, thereby saving the driving force of the first lifting driving member 440.

[0036] In an optional embodiment, each vacuum mesh plate 420 includes a connected mesh plate body 421 and a connecting bracket 422, one end of the connecting bracket 422 is slidably connected to the rotating bracket 430 along the extension direction of the rotation center axis of the rotating bracket 430, and the other end of the connecting bracket 422 is connected to the mesh plate body 421, and the connecting bracket 422 is provided with a first connecting portion 422b on the side facing the operating platform 100, and the first connecting portion 422b is provided with an avoidance opening 422b1, and the output shaft of each first lifting drive member 440 is provided with a second connecting portion 441, and the rotating drive member 410 can drive each connecting bracket 422 to rotate together through the rotating bracket 430, so that the flange portion 441a of the second connecting portion 441 is inserted into the avoidance opening 422b1 to connect the vacuum mesh plate 420 with the first lifting drive member 440. The first connection part 422b and the second connection part 441 in this solution are connected by plug-in matching, which has good stability and is conducive to improving the stability of the vacuum mesh plate 420 during the lifting process and the process of laminating the auxiliary material 520. Of course, the vacuum mesh plate 420 and the first lifting drive member 440 can also be connected by magnetic connection.

The first plate segment and the third plate segment extend along opposite sides of the second plate segment respectively. The first plate segment is connected to the bracket body of the connecting bracket 422. The flange portion 441a of the second connecting portion 441 can be inserted into the avoidance opening 422b1, and the flange portion 441a can be positioned and matched with the top surface or the bottom surface of the internal space of the avoidance opening 422b1, thereby driving the vacuum mesh plate 420 to rise and fall. In another optional embodiment, the bonding device further includes a feeding device 710 and a deviation correction device 720 disposed on the operating platform 100, wherein the feeding device 710 is used to place the product 510 on the carrier 600. Optionally, the feeding device 710 includes a conveying member 711 and a manipulator 712, wherein the conveying member 711 is used to convey the product 510, and the manipulator 712 is used to place the product 510 conveyed by the conveying member 711 on the carrier 600. The carrier 600 is disposed on the deviation correction device 720, and the deviation correction device 720 is used to adjust the position of the carrier 600 so that the carrier 600 is located at the bonding position. That is to say, the carrying platform 600 can move relative to the operating platform 100. When the feeding device 710 places the product 510 on the carrying platform 600, the correcting device 720 can adjust the position of the carrying platform 600 so that the carrying platform 600 moves to the bonding position. At the same time, the vacuum mesh plate 420 moves to the bonding position. At this time, the auxiliary material 520 sucked by the vacuum mesh plate 420 is directly opposite to the product 510 carried by the carrying platform 600, so that the auxiliary material 520 can be accurately bonded to the product 510; in addition, since the carrying platform 600 can move relative to the operating platform 100, when the feeding device 710 places the product 510 on the carrying platform 600, the carrying platform 600 can be staggered from the bonding position, which can avoid interference between the manipulator 712 and other structures at the bonding position. Of course, the correcting device 720 can also be not provided, and the carrying platform 600 can be fixed at the bonding position.

[0039] In a further optional embodiment, the operating platform 100 further has a first image acquisition position and a second image acquisition position arranged at intervals, and the material taking position, the first image acquisition position and the bonding position are arranged in sequence at intervals around the rotating driving member 410 and along the rotation direction of the rotating driving member 410. The bonding device also includes a first image acquisition member 730, a second image acquisition member 740 and a control member arranged on the operating platform 100. Optionally, the first image acquisition member 730 and the second image acquisition member 740 can both be cameras. The first image acquisition member 730 is located at the first image acquisition position of the operating platform 100, and the second image acquisition member 740 is located at the second image acquisition position of the operating platform 100. The image acquisition component 740 is located at the second image acquisition position of the operating platform 100. The first image acquisition component 730, the second image acquisition component 740 and the correction device 720 are all electrically connected to the control component. The first image acquisition component 730 is used to obtain the first image information of the vacuum screen 420 and the auxiliary material 520 sucked therein, and the second image acquisition component 740 is used to obtain the second image information of the carrier platform 600 and the product 510 carried thereon. The control component can control the correction device 720 to move according to the first image information and the second image information to adjust the position of the carrier platform 600 so that the carrier platform 600 is located in the bonding position.

[0040] After the vacuum mesh plate 420 absorbs the auxiliary material 520, the rotary driving member 410 drives the vacuum mesh plate 420 to rotate to the first image acquisition position first, and the first image acquisition member 730 acquires the first image information of the vacuum mesh plate 420 and the auxiliary material 520 absorbed by it, and then the rotary driving member 410 drives the vacuum mesh plate 420 to rotate to the bonding position again; at the same time, when the feeding device 710 places the product 510 on the carrier 600, the correction device 720 first drives the carrier 600 to move to the second image acquisition position, and the second image acquisition member 740 acquires the second image information of the carrier 600 and the product 510 it carries, and then the control member controls the correction device 720 to continue working according to the first image information and the second image information, and the correction device 720 drives the carrier 600 to move to the bonding position again, so that the product 510 is directly opposite to the auxiliary material 520, thereby improving the accuracy of the auxiliary material 520 being bonded to the product 510.

[0041] In another optional embodiment, the correcting device 720 includes a first driving member 721, a second driving member 722 and a third driving member 723. The first driving member 721 is arranged on the operating platform 100, the second driving member 722 is connected to the output shaft of the first driving member 721, the third driving member 723 is connected to the output shaft of the second driving member 722, and the supporting platform 600 is connected to the output shaft of the third driving member 723. The first driving member 721 can drive the second driving member 722, the third driving member 723 and the supporting platform 600 to move together along the first direction, the second driving member 722 can drive the third driving member 723 and the supporting platform 600 to move together along the second direction, and the third driving member 723 can drive the supporting platform 600 to move along the third direction, wherein the first direction and the second direction are both perpendicular to the third direction, and the third direction is perpendicular to the supporting surface of the operating platform 100. In this solution, the first driving member 721, the second driving member 722 and the third driving member 723 respectively drive the carrying platform 600 to move in three directions, and the position of the carrying platform 600 can be flexibly adjusted in three-dimensional space, which is conducive to improving the accuracy of the relative position of the product 510 and the auxiliary material 520, so that the auxiliary material 520 can be accurately attached to the product 510. Of course, one of the first driving member 721 and the second driving member 722 can also be omitted.

[0042] Optionally, at least one of the first driving member 721 , the second driving member 722 and the third driving member 723 may be a motor, a cylinder, a hydraulic cylinder, etc., and this embodiment of the present application does not impose any specific limitation on this.

[0043] In a further optional embodiment, the first driving member 721 is a double-headed linear motor having two output shafts, which can move independently. Of course, it can also be set as two independent first driving members 721. There are two second driving members 722, each of which is arranged at intervals along the length direction of the first driving member 721, and each of the second driving members 722 is connected to each output shaft of the first driving member 721 in a one-to-one correspondence, and the third driving member 723 and the carrier 600 are both set in a one-to-one correspondence with the second driving member 722. In this scheme, there are two carriers 600, including a first carrier and a second carrier arranged at intervals. When the first carrier is located at the loading position, the manipulator 712 of the feeding device 710 places the product 510 on the conveying member 711 on the first carrier, and then the deviation correction device 720 drives the first carrier to move to the bonding position, so that the auxiliary material 520 is bonded to the product 510 on the first carrier; at the same time, the second carrier moves to the loading position under the drive of the deviation correction device 720, and the manipulator 712 of the feeding device 710 places the product 510 on the conveying member 711 on the second carrier. When the first carrier leaves the bonding position, the second carrier carries the product 510 to the bonding position, and the first carrier returns to the loading position, and the cycle is repeated. This scheme sets two carriers 600 so that the loading process (i.e., product) and the bonding process of the auxiliary material 520 are carried out simultaneously, thereby improving the working efficiency of the bonding equipment bonding the auxiliary material 520. Of course, the number of carriers 600 can also be one.

[0044] In another optional embodiment, the operating platform 100 also has a discharging position, and the material taking position, the bonding position and the discharging position are arranged around the rotating driving member 410 and in sequence along the rotation direction of the rotating driving member 410. The bonding equipment also includes a discharging device 750 arranged on the operating platform 100, and the discharging device 750 is located at the discharging position. When the vacuum mesh plate 420 is located at the discharging position, the vacuum mesh plate 420 breaks the vacuum so that the product 510 is placed on the discharging device 750. The vacuum breaking here specifically refers to the introduction of air into the cavity of the vacuum mesh plate 420 (for example, an air inlet is opened on the middle frame 421c) to balance the air pressure in the cavity, so that the pressure difference inside and outside the cavity is reduced or even equalized. After the vacuum mesh plate 420 absorbs the product 510, the vacuum mesh plate 420 rises, and then the rotary drive member 410 drives the vacuum mesh plate 420 to rotate to the discharge position, and then the vacuum mesh plate 420 descends to make the product 510 contact the discharge device 750, and then the vacuum mesh plate 420 breaks the vacuum to place the product 510 on the discharge device 750. In this solution, the discharge position and the bonding position are staggered, which not only facilitates the arrangement of the discharge device 750, but also reduces the time that the vacuum mesh plate 420 stays at the bonding position, thereby improving the working efficiency of bonding the auxiliary material 520.

[0045] In an embodiment in which the vacuum suction device 400 also includes at least two first lifting drive members 440, the operating platform 100 also has a discharge position, and the material taking position, the bonding position and the discharge position are arranged in sequence around the rotating drive member 410 and along the rotation direction of the rotating drive member 410. The discharge position is provided with a first lifting drive member 440. When the vacuum mesh plate 420 is located at the discharge position, the first lifting drive member 440 located at the discharge position can be connected to the vacuum mesh plate 420 located at the discharge position, and drive the vacuum mesh plate 420 located at the discharge position to rise and fall.

[0046] Optionally, both the conveying member 711 and the discharging device 750 can be conveyor belt conveying devices, which move more smoothly to facilitate the conveyance of the product 510.

[0047] In an optional embodiment, the rolling device 200 includes a device body 210, a rolling drive member 220, a second lifting drive member 230 and a rolling member 240. Optionally, at least one of the rolling drive member 220 and the second lifting drive member 230 can be a motor, a cylinder, a hydraulic cylinder, etc., and the embodiment of the present application does not impose specific restrictions on this. The device body 210 is arranged on the operating platform 100, the rolling drive member 220 is arranged on the device body 210, the second lifting drive member 230 is connected to the output shaft of the rolling drive member 220, and the rolling member 240 is connected to the output shaft of the second lifting drive member 230. The rolling member 240 can be pressed on the vacuum mesh plate 420, and the rolling drive member 220 can drive the second lifting drive member 230 and the rolling member 240 to move together relative to the vacuum mesh plate 420. The second lifting drive member 230 can drive the rolling member 240 to rise and fall so that the rolling member 240 is close to or away from the vacuum mesh plate 420. The vacuum mesh plate 420 includes a connected mesh plate body 421 and a connecting bracket 422. The mesh plate body 421 is connected to the output shaft of the rotating drive member 410 through the connecting bracket 422. The connecting bracket 422 is provided with a guide structure 422a, and the guide structure 422a is overlapped with the mesh plate body 421. The rolling member 240 can be guided and matched with the guide structure 422a.

[0048] When the vacuum mesh plate 420 and the carrier 600 are both located at the bonding position, the second lifting drive 230 drives the rolling member 240 to descend, so that the rolling member 240 is pressed on the vacuum mesh plate 420, and then the rolling drive 220 drives the second lifting drive 230 and the rolling member 240 to move together relative to the vacuum mesh plate 420, so as to bond the auxiliary material 520 to the product 510. During the movement of the rolling member 240 relative to the vacuum mesh plate 420, the rolling member 240 cooperates with the guide structure 422a to prevent the rolling member 240 from tilting, thereby improving the working efficiency of bonding the auxiliary material 520. Of course, the guide structure 422a may not be provided.

[0049] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
