DETAILED DESCRIPTION

[0044] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0046] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0047] Figure 1 and Figure 2 A bonding and pressure-maintaining device is provided in an embodiment of the present application, which includes a positioning mechanism 1 and a bonding and pressure-maintaining mechanism 2. The positioning mechanism 1 is used to provide positioning support for the workpiece 2000 to be processed, and the pressure-maintaining bonding mechanism 2 is used to bond auxiliary materials and perform pressure-maintaining operations on the workpiece 2000 to be processed.

[0048] Among them, the positioning mechanism 1 includes a plurality of support bosses 12 arranged at intervals, and the support bosses 12 are used to place the workpiece 2000 to be processed, so as to play a positioning and supporting role for the workpiece 2000 to be processed; the material of the side of the support boss 12 facing the workpiece 2000 to be processed is a flexible material, so that the contact between the support boss 12 and the workpiece 2000 is soft contact, which can avoid hard contact between the support boss 12 and the workpiece 2000, and play a protective role for the workpiece 2000 to be processed.

[0049] The fitting and pressure-maintaining mechanism 2 includes a fitting and pressure-maintaining component 22, which is arranged corresponding to the supporting boss 12, and the material of the side of the fitting and pressure-maintaining component 22 facing the supporting boss 12 is a flexible material; after the workpiece 2000 to be processed is placed on the supporting boss 12, the fitting and pressure-maintaining component 22 abuts against the side of the workpiece 2000 to be processed that is away from the supporting boss 12, and presses the workpiece 2000 to perform fitting auxiliary materials and pressure-maintaining operations on the workpiece 2000.

[0050] In this application, the support boss 12 and the laminating and pressure-maintaining assembly 22, which contact the workpiece 2000, are both made of a flexible material. This allows for flexible contact between the support boss 12 and the workpiece 2000, as well as between the laminating and pressure-maintaining assembly 22 and the workpiece 2000. This prevents damage to the workpiece 2000 caused by hard contact with the workpiece 2000 during laminating or pressure-maintaining. The flexible material also accommodates a variety of auxiliary materials during pressure-maintaining, enabling simultaneous pressure-maintaining of multiple materials. This is particularly suitable for laminating and pressure-maintaining thin, easily deformed, and irregularly shaped auxiliary materials.

[0051] This bonding and pressure-maintaining device is used in the production process of the workpiece 2000 to be processed, referring to Figure 1 The positioning mechanism 1 further comprises a positioning assembly 11, which comprises a fixed seat 111 and a positioning turntable 112, wherein the fixed seat 111 is connected to the positioning turntable 112. The supporting boss 12 is convexly arranged on a side of the positioning turntable 112 away from the fixed seat 111. When it is necessary to bond auxiliary materials to the workpiece 2000, the workpiece 2000 to be bonded with the auxiliary materials can be placed on the supporting boss 12; then the positioning turntable 112 is grabbed by the robot, and the positioning turntable 112 is fixedly assembled on the fixing seat 111, and the positioning turntable 112 is positioned and fixed by the fixing seat 111, and the bonding and pressure holding mechanism 2 is used there to bond auxiliary materials and perform pressure holding operations on the workpiece 2000. After the auxiliary material bonding and pressure holding processes are completed, the positioning turntable 112 is grabbed by the robot and placed on the assembly line to continue to complete the next process of the workpiece 2000. In this way, the workpiece 2000 can be always placed in the positioning turntable 112 during the processing flow of the workpiece 2000. There is no need to take out the workpiece 2000. The automated flow can be completed by grabbing the positioning turntable 112 by the robot, and at the same time, it is avoided that the robot grabs the workpiece 2000 and causes damage to the workpiece 2000.

[0052] Of course, in the actual processing and production process, the positioning turntable 112 can also be first fixedly assembled on the fixing seat 111, and then the workpiece 2000 to be processed and the auxiliary materials to be bonded can be placed on the positioning turntable 112.

[0053] For example, Figure 12 and Figure 13The workpiece 2000 shown is a camera decorative part. For example, the camera decorative part includes a material-attaching portion 2100 in the middle and an outer edge convex portion 2200 arranged around the material-attaching portion 2100, so as to enclose a first abutting groove 2003 and a second abutting groove 2004 on two opposite sides, wherein the second abutting groove 2004 can be pasted with auxiliary materials. Figure 13 The outer periphery of the outer edge protrusion 2200 has a serrated right-angled surface, eliminating the need for additional materials. The camera decorative piece includes a flash; the flash is an additional material. The flash structure of the workpiece 2000 is small, and the material is susceptible to cracking and damage when subjected to stress.

[0054] Support boss 12 is inserted Figure 12 The first abutment groove 2003 of the camera decorative part shown in the figure serves to position and support the material-attaching part 2100 of the camera decorative part, so that the outer edge protrusion 2200 that does not need to be attached with auxiliary materials is suspended in the air. In this way, the workpiece 2000 is prevented from contacting the edges of the workpiece 2000 when the auxiliary materials are attached and the pressure is maintained, thereby avoiding damage to the appearance of the workpiece 2000. At the same time, the size of the supporting boss 12 and the fitting and pressure-maintaining component 22 can also be reduced, thereby reducing costs.

[0055] Preferably, the inner diameter of the first abutment groove 2003 of the workpiece 2000 to be processed is equal to or slightly larger than the outer diameter of the support boss 12. In this way, combined with the support boss 12 protruding from the positioning turntable 112, the outer edge protrusion 2200 can be ensured to be in a suspended state.

[0056] For example, the side of the support boss 12 facing the workpiece 2000 is made of 70U hardness rubber, with a deformation of ≤0.2mm, which can provide a buffering and protective effect when in contact with the workpiece 2000. The side of the support boss 12 in contact with the workpiece 2000 can also be made of other flexible materials, which is not limited here.

[0057] refer to Figure 5 In this embodiment, two spaced support bosses 12 are provided on the positioning turntable 112. In this way, the two workpieces 2000 to be processed can be simultaneously subjected to the laminating and pressure-maintaining operations on the two support bosses 12, thereby improving the production and processing efficiency.

[0058] In other embodiments, the number of the supporting bosses 12 may be one, three, four, or more.

[0059] like Figure 6As shown, in the technical solution of this embodiment, the positioning turntable 112 is provided with a mounting groove 112a, and the support boss 12 is disposed within the mounting groove 112a, and the support boss 12 protrudes from the notch of the mounting groove 112a. The mounting groove 112a provides a mounting and positioning base for the support boss 12, and the support boss 12 is designed to be detachable from the positioning turntable 112. According to actual needs, the support boss 12 of different heights can be replaced to avoid hard contact between the workpiece 2000 and the positioning turntable 112.

[0060] In this embodiment, the groove wall of the mounting groove 112a and the support boss 12 are first connected by adhesive to achieve initial positioning, and then connected by screws to improve connection stability. In other embodiments, the mounting groove 112a and the support boss 12 can also achieve initial positioning through positioning and then be fixedly connected by screws. The positioning and matching can be achieved by the matching of a protrusion and a groove.

[0061] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, the positioning assembly 11 further includes a first positioning column 113, the first positioning column 113 protrudes from the side of the support boss 12 away from the positioning turnover table 112; the workpiece 2000 is provided with a first positioning hole 2001, reference Figure 12 The first positioning hole 2001 is provided in the material-applying portion 2100 of the workpiece 2000 to be processed. The first positioning post 113 is positioned and engaged with the first positioning hole 2001. This allows the workpiece 2000 to be positioned and limited on the support boss 12, ensuring the positional stability of the workpiece 2000 during material-applying and pressure-maintaining. Optionally, the first positioning post 113 is provided through the support boss 12 and connected to the positioning turntable 112. Alternatively, in other embodiments, the first positioning post 113 is connected to the support boss 12.

[0062] like Figure 5 As shown, in the technical solution of this embodiment, the support boss 12 is provided with at least two first positioning posts 113, and the two first positioning posts 113 have different sizes. Accordingly, the workpiece 2000 to be processed has two first positioning holes 2001 of different sizes. By providing two first positioning posts 113 of different sizes and cooperating with the two first positioning holes 2001 of different sizes, a foolproof effect can be achieved.

[0063] Some of the workpieces 2000 to be processed have a relatively brittle or thin structure and are prone to breakage, such as Figure 12 and Figure 13 In the figure, the flash of the camera decoration is the fragile object 2002. The fragile object 2002 can withstand less pressure than other auxiliary materials of the patch part 2100 of the workpiece 2000 to be processed. If the supporting boss 12 directly abuts against the fragile object 2002, it is easy to cause the fragile object 2002 to break.

[0064] To solve this problem, Figure 6 As shown, in the technical solution of this embodiment, the positioning assembly 11 has a first through hole 11a, which passes through the supporting boss 12 and the positioning turntable 112. The first through hole 11a is used to correspond to the fragile object 2002 of the workpiece 2000 to be processed. An elastic support platform 114 is provided in the first through hole 11a for elastically abutting the fragile object 2002. When a thinner and more fragile auxiliary material (such as a flash lamp) is attached to the workpiece 2000 and during the pressure holding process, the fragile object 2002 abuts against the elastic support platform 114, which acts as an elastic buffer for the fragile object 2002. In this way, the same supporting boss 12 at the same workstation can meet the different pressure requirements when attaching the fragile object 2002 and other auxiliary materials, allowing different auxiliary materials to be attached and pressure-held at the same workstation, without the need for separate attachment and pressure-holding operations for the fragile auxiliary material. This embodiment completes the pressure maintenance of all auxiliary materials in one piece, which can effectively ensure that quality, efficiency, and yield are greatly improved, personnel operations are comfortable, and personnel costs are rapidly reduced.

[0065] like Figure 6 As shown, in the technical solution of this embodiment, the elastic support platform 114 includes a support head 1141, a base plate 1142, and an elastic member 1143. The support head 1141 is disposed in the first through hole 11a and is used to abut against the fragile object 2002. The base plate 1142 is disposed on the side of the positioning turntable 112 facing the fixed seat 111 and is arranged corresponding to the first through hole 11a. The elastic member 1143 is disposed in the first through hole 11a, and the two ends of the elastic member 1143 abut against the support head 1141 and the base plate 1142 respectively. The support head 1141 is used to support the fragile object 2002, and the support head 1141 is movable and limited in the first through hole 11a, playing a guiding role, thereby solving the problem of deformation and deviation under stress. The elastic member 1143 can be any one of a spring, a washer, and a rubber bearing, as long as it can play an elastic supporting role and ultimately achieve a buffering effect.

[0066] The bottom plate 1142 is sealed and fixed to the side of the positioning turntable 112 facing the fixed seat 111, and is used to support the support head 1141 and the elastic member 1143. The bottom plate 1142 is detachably arranged on the positioning turntable 112. Different elastic support platforms 114 can be replaced according to the shapes of different fragile objects 2002 and different pressure requirements, thereby effectively achieving the purpose of separately disassembling, debugging and replacing auxiliary materials on the positioning turntable 112, so as to improve the scope of application of the positioning turntable 112.

[0067] For the fragile object 2002, it includes a fragile area and a stress-bearing area. The stress-bearing area can withstand greater pressure than the fragile area. Therefore, when the support head 1141 is brought into contact with the fragile object 2002, the support head 1141 is usually brought into contact with the stress-bearing area. Figure 6 A contoured protrusion 1412 is provided on the side of the support head 1141 facing the fragile object 2002. The contoured protrusion 1412 is adapted to the shape of the force-bearing area of ​​the fragile object 2002 so that the contoured protrusion 1412 abuts against the force-bearing area and avoids the fragile area.

[0068] The contoured protrusion 1412 provides a buffering and protective effect on the fragile object 2002. The contoured protrusion 1412 is made of silicone, which ensures wear resistance, deformation resistance, precision, hardness, resistance to biological aging, high strength, high elasticity, and long life. To improve stability, the support head 1141 can be made of steel.

[0069] Taking the flash of a camera trim as an example, the flash's edge is a stress-bearing area and can withstand high pressure. The CD surface of the flash is a vulnerable area. The flash's edge is attached to the camera trim via adhesive. During pressure maintenance, under a certain pressure, the adhesive on the flash's edge can be activated, allowing the flash to adhere tightly to the camera trim. The contoured protrusion 1412 is designed to correspond to the shape of the flash's edge, avoiding the CD surface. This ensures that the CD surface of the flash is not damaged during the bonding and pressure maintenance process. During pressure maintenance, the flash's edge is clamped by the contoured protrusion 1412 and the bonding and pressure maintenance assembly 22, and the pressure it experiences is greater than the pressure on the CD surface. This satisfies the conditions for activating the adhesive while simultaneously reducing the pressure on the CD surface, ensuring that the CD surface of the flash is not damaged during pressure maintenance.

[0070] In one embodiment, the contoured protrusion 1412 is formed by injection molding. Specifically, an insert mold is used to inject silicone raw material to form the contoured protrusion 1412 on the support head 1141. The shape of the contoured protrusion 1412 needs to be contoured to the wall of the flash lamp, avoiding the CD texture surface of the flash lamp.

[0071] like Figure 6 As shown, in the technical solution of this embodiment, a buffer groove is provided at one end of the support head 1141 away from the contoured protrusion 1412 , and the elastic member 1143 is inserted into the buffer groove.

[0072] In order to facilitate the positioning of the turnover table 112 during the circulation process, the positioning turnover table 112 and the fixed seat 111 are quickly positioned and matched. Figure 3 and Figure 7In the technical solution of this embodiment, the fixed seat 111 has a first positioning structure; the positioning turntable 112 has a second positioning structure, and the second positioning structure is positioned and matched with the first positioning structure; in this way, the fixed seat 111 and the positioning turntable 112 are designed to be separable structures, and the fixed seat 111 and the positioning turntable 112 can be quickly positioned and connected through positioning matching, which can facilitate the transfer of the positioning turntable 112 to different fixed seats 111 through a robot.

[0073] The positioning component 11 of the present application can be used to fix the workpiece 2000 that is not foolproof, uneven, thin, easily deformed, irregularly shaped, or has high requirements on appearance, and the positioning turntable 112 can carry the workpiece 2000 to be processed for turnover on the assembly line, and then use an automated suction nozzle or a robot to take the positioning turntable 112 on the assembly line, and then fix it on the fixed seat 111. The positioning turntable 112 is guided and limited by the second positioning structure of the fixed seat 111 to realize automated operation.

[0074] The first positioning structure is a positioning block or positioning hole provided on the side of the fixed seat 111 facing the positioning turntable 112, and the second positioning structure is a positioning hole or positioning block correspondingly provided on the side of the positioning turntable 112 facing the fixed seat 111, and the positioning block is provided in the positioning hole.

[0075] For example, Figure 4 and Figure 7 As shown, in the technical solution of this embodiment, the first positioning structure includes a second positioning post 1111, which protrudes from the side of the fixed seat 111 facing the positioning turntable 112; the second positioning structure includes a second positioning hole 112b, which is provided on the side of the positioning turntable 112 facing the fixed seat 111; the second positioning hole 112b is positioned and matched with the second positioning post 1111 to achieve rapid matching between the fixed seat 111 and the positioning turntable 112. Optionally, to protect the second positioning hole 112b, a first sleeve 115 is provided within the second positioning hole 112b, and the first sleeve 115 is positioned and matched with the second positioning post 1111.

[0076] For example, refer to Figure 2 and Figure 4 The fixing seat 111 is provided with a first mounting hole 111a, and one end of the second positioning column 1111 is inserted into the first mounting hole 111a; the other end of the second positioning column 1111 protrudes from the side of the fixing seat 111 facing the positioning turntable 112, and is positioned and matched with the first sleeve 115.

[0077] In other embodiments, the positions of the second positioning post and the first positioning hole may be interchanged, that is, the second positioning structure includes the second positioning post, and the first positioning structure includes the second positioning hole.

[0078] In this embodiment, reference Figure 4 , the number of the first mounting holes 111a is two, the number of the second positioning columns 1111 is two, and the outer circumferential dimensions of the two first matching portions are different; Figure 7 , the number of the second positioning holes 112b is two.

[0079] There are two first sleeves 115 , and the inner diameters of the two first sleeves 115 are different. Each first sleeve 115 is adapted to the outer dimensions of the first matching portion of a second positioning column 1111 , so that fast assembly and positioning can be achieved while preventing mistakes.

[0080] In other embodiments, the number of the first mounting holes 111a may be one, three, four, or more. Correspondingly, the number of the second positioning holes 112b may be one, three, four, or more.

[0081] In the technical solution of this embodiment, the first mounting hole 111a is a non-circular hole, and the shape of the portion of the second positioning post 1111 inserted into the first mounting hole 111a is adapted to the shape of the first mounting hole 111a. In this way, it can play a limiting role, preventing the second positioning post 1111 and the fixing seat 111 from rotating relative to each other. The inner cavity of the first sleeve 115 is a non-circular hole, which can play a limiting role, preventing the second positioning post 1111 and the positioning turntable 112 from rotating relative to each other. In other words, the edge of the second positioning post 1111 cooperates with the first sleeve 115 and the second positioning hole 112b to play a limiting role, which can effectively solve the problem of precision shaking and improve the stability of the matching position of the positioning turntable 112 and the fixing seat 111.

[0082] In this embodiment, the second positioning column 1111 is made of metal. In other embodiments, the second positioning column 1111 may also be made of other materials and is not limited to metal.

[0083] In the technical solution of this embodiment, all first sleeves 115 used have a certain thickness, which can effectively ensure accuracy and wear cycle. In a specific embodiment, the thickness of the first sleeve 115 is 2.5 mm.

[0084] like Figure 4 As shown, in the technical solution of this embodiment, at least two guide blocks 1112 are provided on the side of the fixed seat 111 facing the positioning turntable 112, and the two guide blocks 1112 are both L-shaped; the two guide blocks 1112 are arranged at intervals and enclosed with the surface of the fixed seat 111 to form an assembly groove 111b.

[0085] like Figure 4 and Figure 7As shown, the positioning turntable 112 is located in the assembly groove 111b. The assembly groove 111b plays a positioning and limiting role for the positioning turntable 112.

[0086] It is understood that the two L-shaped guide blocks 1112 are designed to prevent overall fooling, and the two guide blocks 1112 are designed diagonally to prevent fooling and avoid positioning deviation of the turntable 112. In one embodiment, the guide blocks 1112 are made of white steel.

[0087] In order to ensure the precise positioning of the bonding and pressure-maintaining mechanism and the positioning mechanism of the workpiece to be processed and to ensure the position stability of the bonding and pressure-maintaining device when bonding the auxiliary materials and maintaining the pressure, the technical solution of this embodiment refers to Figure 1 and Figure 2 The fitting and pressure-maintaining mechanism 2 also includes an installation component 21 and a first guide structure 23. The fitting and pressure-maintaining component 22 is arranged on the installation component 21. The installation component 21 is guided and cooperated with the positioning component 11 through the first guide structure 23. The first guide structure 23 can guide the movement of the installation component 21.

[0088] When performing the laminating and pressure-maintaining operations, the mounting assembly 21 drives the laminating and pressure-maintaining assembly 22 to move toward the support boss 12 until the laminating and pressure-maintaining assembly 22 abuts against the side of the workpiece 2000 facing away from the support boss 12 and presses the workpiece 2000.

[0089] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the mounting assembly 21 is guided and matched with the fixing seat 111 through the first guide structure 23. The fixing seat 111 can be fixed on the machine plane to fix the positioning turntable 112 and guide the laminating and pressure-maintaining assembly 22. The positioning turntable 112 can be shared by multiple fixing seats 111 during turnover.

[0090] like Figure 1 As shown, in the technical solution of this embodiment, the mounting assembly 21 is connected to the fixing seat 111 through the first guide structure 23. The mounting assembly 21 is provided with a first guide hole, referring to Figure 3 The fixing seat 111 is provided with a third positioning hole 111c; the two ends of the first guide structure 23 are respectively inserted into the third positioning hole 111c and the first guide hole. Optionally, the first guide structure 23 is a guide column.

[0091] It is understandable that the first guide structure 23 cooperates with the third positioning hole 111c to achieve the connection and fixation of the fitting and pressure-maintaining mechanism 2 and the positioning mechanism 1, thereby playing an overall guiding role when the installation component 21 drives the fitting and pressure-maintaining component 22 to move.

[0092] Optionally, in order to protect the third positioning hole 111c, refer to Figure 4 A second sleeve 116 is provided in the third positioning hole 111 c , and the first guide structure 23 passes through the second sleeve 116 .

[0093] like Figure 5 As shown, in the technical solution of this embodiment, a fourth positioning hole 112c is further provided on the side of the positioning turntable 112 away from the fixing seat 111. The number of the fourth positioning holes is not limited. A third sleeve 117 is provided in the fourth positioning hole. The provision of the third sleeve 117 can improve the contact smoothness and make the fourth positioning hole less prone to wear, thereby solving the problem of poor precision caused by wear of the fourth positioning hole. The material of the third sleeve 117 is copper. Figure 5 As shown, for example, the positioning turntable 112 has protrusions at both ends of the side facing away from the fixing base 111, and the fourth positioning holes are provided in the protrusions. Each protrusion is provided with a plurality of fourth positioning holes 112c. During the auxiliary material lamination and pressure holding process, to ensure the accuracy of the auxiliary material lamination position, the fourth positioning holes 112c can serve as a correction guide and positioning function.

[0094] The part of the fitting and pressure-maintaining component 22 that contacts the workpiece 2000 is made of flexible material, which will increase the adhesion between the fitting and pressure-maintaining component 22 and the workpiece 2000 to a certain extent. It may cause the workpiece 2000 to stick to the fitting and pressure-maintaining component 22 when the fitting and pressure-maintaining component 22 are separated from the workpiece 2000, causing the workpiece 2000 to be driven by the fitting and pressure-maintaining component 22 to shake or detach from the supporting boss 12, causing the workpiece 2000 to shift or fall off.

[0095] To solve this technical problem, Figure 2As shown, in the technical solution of this embodiment, the fitting and pressure-keeping mechanism 2 has a second through hole 2a; the second through hole 2a passes through the fitting and pressure-keeping component 22 and the mounting component 21; the second through hole 2a is arranged corresponding to the support boss 12; the fitting and pressure-keeping mechanism 2 also includes a push mold 25, and the mounting component 21 includes a mounting seat 211, and the mounting seat 211 is located on the side of the positioning turntable 112 away from the fixed seat 111, and the fitting and pressure-keeping component 22 is arranged on the side of the mounting seat 211 facing the positioning turntable 112; the second through hole 2a passes through the fitting and pressure-keeping component 22 and the mounting seat 211; the push mold 25 is arranged in the second through hole 2a; the push mold 25 is used to elastically abut against the workpiece 2000 to be processed. The mounting seat 211 drives the laminating and pressure-maintaining component 22 to move toward the supporting boss 12 until the laminating and pressure-maintaining component 22 is pressed against the workpiece 2000 to perform the laminating and pressure-maintaining operations. After the laminating and pressure-maintaining operations are completed, the laminating and pressure-maintaining component 22 moves in the opposite direction to separate from the workpiece 2000. In order to prevent the workpiece 2000 from sticking to the laminating and pressure-maintaining component 22 during the separation process, a push mold 25 is provided to hold the workpiece 2000 against the laminating and pressure-maintaining component, thereby ensuring smooth separation of the laminating and pressure-maintaining component 22 from the workpiece 2000.

[0096] refer to Figure 9 、 Figure 10 and Figure 11 In the technical solution of this embodiment, the ejection mold member 25 includes a connecting portion 251, an elastic portion 253, and a movable portion 252. The connecting portion 251 is connected to the mounting seat 211; one end of the movable portion 252 protrudes from the fitting and pressure-maintaining assembly, and the other end is disposed within the second through hole 2a. The elastic portion 253 is disposed between the connecting portion 251 and the movable portion 252, with the two ends of the elastic portion 253 respectively connected to the connecting portion 251 and the movable portion 252. The movable portion 252 is configured to abut against the workpiece 2000. When the fitting and pressure-maintaining assembly 22 presses against the workpiece 2000, the movable portion 252 is squeezed and moved by the reaction force of the workpiece 2000, thereby squeezing the elastic portion 253, causing the elastic portion 253 to deform and accumulate elastic potential energy. When the bonding and pressure-maintaining component 22 is separated from the workpiece 2000, the elastic portion 253 releases elastic potential energy, thereby causing the movable portion 252 to continue to press against the workpiece 2000 and exerting a force on the workpiece 2000 that is away from the moving direction of the bonding and pressure-maintaining component 22, so that the workpiece 2000 is smoothly separated from the bonding and pressure-maintaining component 22, thereby preventing the workpiece 2000 from being stuck to the bonding and pressure-maintaining component 22 and moving.

[0097] Optionally, refer to Figure 11A buckle 254 is provided on the end of the connecting portion 251 away from the elastic portion 253. This buckle 254 secures the connecting portion 251 to the mounting base 211. This facilitates installation and removal of the ejector 25, and allows replacement of the elastic portion 253 with different elastic coefficients or the movable portion 252 with a different material as needed. Preferably, the movable portion 252 is made of a material with low viscosity or no adhesion to the workpiece 2000.

[0098] In the technical solution of this embodiment, the side of the fitting and pressure-maintaining component 22 facing the supporting boss 12 includes a plurality of buffer members, and the plurality of buffer members are arranged in a one-to-one correspondence with the plurality of supporting bosses 12 .

[0099] For example, Figure 9 As shown, in the technical solution of this embodiment, the fitting and pressure-maintaining component 22 also includes a first buffer 221 and a second buffer 222. The first buffer 221 is provided on the side of the mounting seat 211 facing the positioning turntable 112; the second buffer 222 is provided on the side of the first buffer 221 facing the positioning turntable 112, and the second buffer 222 is provided one-to-one with the support boss 12; the side of the second buffer 222 facing the support boss 12 is adapted to the workpiece 2000 to be processed; wherein, the first buffer 221 and the second buffer 222 are both made of flexible material. The first buffer 221 and the second buffer 222 can be integrally formed or separately designed. The size of the second buffer 222 is smaller than that of the first buffer 221. The second buffer 222 is provided corresponding to the support boss 12 to form a convex structure. The convex structure can play a role in concentrating force, so that the force point is concentrated at the convex position, thereby solving the problem of interference force on steps on different surfaces. The first buffer member 221 serves to disperse and cushion the forces acting on the second buffer member 222. Optionally, the laminating and pressure-maintaining component 22 is made of silicone, which deforms when applied to the workpiece 2000. Optionally, the first buffer member 221 and the second buffer member 222 may be made of different flexible materials.

[0100] Exemplarily, the second buffer member 222 is designed to correspond to the second abutment groove 2004 of the camera decorative member. The outer diameter of the second buffer member 222 is equal to or slightly smaller than the inner diameter of the second abutment groove 2004. When fitting the auxiliary materials and maintaining the pressure, the second buffer member 222 is inserted into the second abutment groove 2004. The edge of the second buffer member 222 is retracted a certain distance relative to the outer edge protrusion 2200 of the workpiece 2000 to be processed. Firstly, it can ensure that the horizontal force of the workpiece 2000 to be processed is concentrated to ensure the pressure holding effect. Secondly, during assembly, it can also avoid contact with the outer edge protrusion 2200 to avoid affecting the appearance of the workpiece 2000 to be processed, and can solve the variation defects caused by the contact of the appearance of the workpiece 2000 to be processed.

[0101] like Figure 8 and Figure 9 As shown, in the technical solution of this embodiment, the mounting assembly 21 includes an adapter block 2111 and a mounting block 2112. The mounting block 2112 is provided with a first guide hole, and the first guide structure 23 is inserted into the first guide hole. The adapter block 2111 is connected to the mounting block 2112. The adapter block 2111 is used to connect to an external structure, so that it can be used in various machines. Optionally, the materials of the adapter block 2111 and the mounting block 2112 are both hardware. The fitting and pressure-maintaining assembly 22 is installed on the side of the mounting block 2112 away from the adapter block 2111. Specifically, the first buffer member 221 is installed on the side of the mounting block 2112 away from the adapter block 2111.

[0102] like Figure 9 As shown, in the technical solution of this embodiment, the laminating and pressure-maintaining assembly 22 further includes a second guide structure 24, and the mounting block 2112 and the first buffer member 221 are guided by the second guide structure 24. Optionally, the second guide structure 24 is a guide column.

[0103] For example, due to the need to simultaneously ensure accuracy, performance, and appearance, the second buffer 222 and the support boss 12 can be made of different types of flexible materials. The second buffer 222 is designed with TPU soft rubber, and is convex in a downward manner so that the convex structure fits and presses the workpiece 2000 against the bottom surface of the second abutment groove 2004 of the workpiece 2000, and interferes with the workpiece 2000. That is, the surface of the second buffer 222 facing the workpiece 2000 is pressed against the material-attaching portion 2100 of the workpiece 2000, so that the adhesive on the back of the workpiece 2000 is activated by force, and the auxiliary material can be attached and pressure maintained. The material of the side of the support boss 12 facing the workpiece 2000 is selected from flexible silicone or polyurethane. When the second buffer 222 is pressed down, the flexible second buffer 222 and the flexible support boss 12 deform to produce an extrusion effect, preventing the workpiece 2000 from deformation and local unevenness, and playing a role in maintaining pressure and solidifying the buffer.
