[0113] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0114] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0115] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0116] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0117] In the drawings herein, any one of direction X, direction Y and direction Z is perpendicular to the other two directions, wherein direction Z is parallel to the height direction.

[0118] In a first aspect, an embodiment of the present application provides a film assembly, which is used to bond a workpiece to a diaphragm. The workpiece may be a part that needs to be protected, such as a housing, screen, battery, or lens of an electronic or electrical device. The diaphragm includes a connected substrate and an adhesive film, wherein the substrate and the adhesive film are separable. After the user uses the film assembly to bond the diaphragm to the workpiece, the user can tear off the substrate so that the adhesive film is bonded to the workpiece, and the adhesive film can play at least one of the following roles: anti-friction, anti-puncture, anti-corrosion, anti-oxidation, and heat dissipation.

[0119] Please refer to Figure 1 As shown, the film sticking assembly 10 includes a base body 1, a cover body 2 and a first positioning member 3. Figure 2-Figure 3 As shown, the base 1 has a pressing position 111a for pressing the diaphragm. The cover 2 is detachably connected to the base 1, and the cover 2 is used to press the workpiece against the diaphragm located at the pressing position 111a so that the workpiece and the diaphragm are attached. The first positioning member 3 is connected to the base 1, and the first positioning member 3 includes the following Figure 3 The positioning portion 3a shown in the figure can move relative to the base body 1 to a position as shown in the figure. Figure 3 The first position shown or Figure 4 The second position shown. When the positioning portion 3a is located at Figure 3 In the first position shown in FIG. 1 , the positioning portion 3a is higher than the plane where the pressing position 111a is located, and the diaphragm is positioned by the positioning portion 3a. Figure 4 In the second position shown, one end of the positioning portion 3a close to the pressing position 111a is lower than the plane where the pressing position 111a is located.

[0120] During the film application process, the user first operates the positioning portion 3a of the first positioning member 3 to move relative to the base body 1 to a position as shown in FIG. Figure 3 The first position shown in the figure, and then the user places the film at the pressing position 111a. Since the positioning portion 3a is higher than the plane where the pressing position 111a is located, that is, the positioning portion 3a is raised relative to the plane where the pressing position 111a is located, the positioning portion 3a can be used to position the film. Among them, the base material of the film can be provided with a positioning hole, and the positioning portion 3a can be inserted into the positioning hole. After the film is positioned at the preset position, the user can operate the positioning portion of the first positioning member 3 to move relative to the base body 1 to the position as shown in the figure. Figure 4 The second position shown, the user can then place the workpiece on the diaphragm, and finally the user can operate the cover 2 to press the workpiece against the diaphragm so that the workpiece and the diaphragm fit tightly. Compared with the positioning member used for positioning the diaphragm in the prior art film assembly, which is prone to structural interference with the workpiece during the process of laminating the diaphragm and the workpiece, the film assembly 10 of the embodiment of the present application has a positioning portion 3a of the first positioning member 3 that can move relative to the seat 1, so that the positioning portion 3a of the first positioning member 3 is not prone to structural interference with the workpiece during the process of laminating the diaphragm and the workpiece, and the workpiece is not easily squeezed and damaged by the positioning portion 3a, and the yield rate of the prepared workpiece is relatively high.

[0121] Among them, the film sticking component 10 can also include a structure for negative pressure adsorption of the diaphragm. At least after the positioning portion 3a moves to the first position and before the workpiece is pressed against the diaphragm by the cover body 2, the film sticking component 10 maintains the state of negative pressure adsorption of the diaphragm, so that the diaphragm can still remain motionless relative to the pressing position 111a after the positioning portion 3a moves to the second position, thereby improving the accuracy of the bonding position between the diaphragm and the workpiece.

[0122] In addition, the film laminating assembly 10 may further include a second positioning member 14 for positioning the workpiece. After the workpiece is placed on the diaphragm and before the workpiece is pressed against the diaphragm by the cover 2, the workpiece is positioned by the second positioning member 14 so that the workpiece is immobile relative to the diaphragm, thereby improving the accuracy of the laminating position between the diaphragm and the workpiece. The number of second positioning members 14 provided may be at least two.

[0123] Furthermore, the first position and the second position are arranged opposite to each other along the direction Z, and the second position is located below the first position. Accordingly, the positioning portion 3a can move in a direction parallel to the direction Z.

[0124] In addition, the number of the first positioning members 3 may be at least two.

[0125] Optionally, the base body 1 has at least two pressing positions 111a, each pressing position 111a is used to press a film and a corresponding workpiece. Therefore, the film laminating assembly 10 of the embodiment of the present application can press at least two films and corresponding workpieces at the same time, and the laminating efficiency is relatively high.

[0126] Optionally, see Figure 3-Figure 5As shown, the seat body 1 is provided with a first passage 121, and the first passage 121 includes a first port 121a and a second port 121b. The first port 121a is used to communicate with the air source device (not shown in the figure), and the first positioning member 3 is arranged through the second port 121b. The air source device can change the air pressure in the first passage 121. Under the condition that the air source device increases the air pressure in the first passage 121, when the air pressure in the first passage 121 is greater than the preset value, the positioning portion 3a of the first positioning member 3 can move from the second position to the first position under the action of the air pressure; under the condition that the air source device reduces the air pressure in the first passage 121, when the air pressure in the first passage 121 is less than the preset value, the positioning portion 3a of the first positioning member 3 can move from the first position to the second position under the action of the air pressure. Compared with the hydraulic drive structure and the electric drive structure, the air path structure for driving the positioning portion 3a of the first positioning member 3 in this embodiment has the advantages of lower manufacturing process difficulty, lower assembly difficulty and lower maintenance difficulty.

[0127] The first port 121a may be directly connected to the gas source device, or the first port 121a may be indirectly connected to the gas source device through other gas paths.

[0128] In other embodiments (not shown in the figure), the film attaching assembly 10 may include an electric drive structure, which can drive the positioning portion 3a of the first positioning member 3 to move between the first position and the second position. Alternatively, the film attaching assembly 10 may include a hydraulic drive structure, which can drive the positioning portion 3a of the first positioning member 3 to move between the first position and the second position.

[0129] Optionally, see Figure 3-Figure 5 As shown, the first positioning member 3 includes a slidingly connected cylinder 31 and a positioning column 32, the cylinder 31 is detachably connected to the seat body 1, the cylinder 31 is fixed relative to the seat body 1, and the cylinder 31 is penetrated through the second port 121b. The cylinder 31 is provided with a second passage 311, the second passage 311 includes a third port 311a and a fourth port 311b, the third port 311a is connected to the second port 121b, and the positioning column 32 is penetrated through the fourth port 311b. The positioning column 32 has the positioning portion 3a described above. The air source device can increase the air pressure in the first passage 121 and the air pressure in the second passage 311. After the air pressure in the second passage 311 is greater than the preset value, the positioning portion 3a of the positioning column 32 can move from the second position to the first position. The air source device can also reduce the air pressure in the first passage 121 and the air pressure in the second passage 311. After the air pressure in the second passage 311 is less than the preset value, the positioning portion 3a of the positioning column 32 can move from the first position to the second position. Since the positioning column 32 is a local structure of the first positioning member 3 , less energy is required to drive the positioning column 32 , so the energy consumption of the air source device is lower.

[0130] Among them, the first positioning member 3 can be a standard pneumatic structural member, and the seat body 1 only needs to include a structure that is detachably connected to the cylinder 31, so that the seat body 1 has the advantages of low manufacturing process difficulty, low assembly precision requirements and low maintenance difficulty.

[0131] In addition, the user can replace different types of first positioning members 3 to meet the needs of positioning different types of diaphragms.

[0132] Furthermore, the positioning column 32 may include a colloid portion 321 and a column 322 connected to each other, the column 322 is slidably connected to the cylinder 31, and the colloid portion 321 is installed on the top of the column 322. In this embodiment, at least part of the structure of the colloid portion 321 can be used as the positioning portion 3a described above, that is, the colloid portion 321 is used to position the diaphragm, the material of the colloid portion 321 is relatively soft, and the colloid portion 321 is not easy to damage the diaphragm. In other embodiments, the colloid portion 321 can also be replaced by a metal part or an injection molded part, and at least part of the structure of the metal part or at least part of the structure of the injection molded part can be used as the positioning portion 3a described above.

[0133] In other embodiments (not shown in the figures), the positioning column 32 may be an integrally formed structural member, wherein the end of the positioning column 32 facing away from the cylinder 31 may serve as the positioning portion 3a described above.

[0134] In addition, the first positioning member 3 may further include a second sealing ring 33, the second sealing ring 33 surrounds the outer wall of the cylinder 31, and the fourth inner wall 121c (curved structural wall) in the seat body 1 for enclosing and forming the first passage 121 can be sealed and connected with the outer wall of the cylinder 31 through the second sealing ring 33, so as to improve the sealing degree of the air path between the first passage 121 and the second passage 311. Therefore, the working reliability of the film sticking assembly 10 is high, and the energy consumption of the air source device is also low.

[0135] In other embodiments (not shown in the figure), the first positioning member 3 may be an integrally formed columnar structure, the first positioning member 3 may be slidably connected to the base 1, and the top end of the first positioning member 3 (the end of the first positioning member 3 in the opposite direction Z) may serve as the positioning portion 3a described above. Under the action of air pressure, the first positioning member 3 may slide relative to the base 1, so that the positioning portion 3a moves between the first position and the second position.

[0136] Optionally, see Figure 5 As shown, the seat body 1 is provided with a first sliding hole 112a, and the seat body 1 includes a first inner wall 112aa (curved structure wall) for enclosing and forming the first sliding hole 112a. Figure 4The positioning column 32 shown is slidably connected. This structural setting is conducive to the positioning portion 3a of the positioning column 32 to accurately slide to the first position along the set direction, thereby improving the positioning accuracy of the positioning column 32. Accordingly, the accuracy of the fitting position between the diaphragm and the workpiece is higher, and the yield rate of the prepared workpiece is higher.

[0137] When the positioning portion 3a of the positioning column 32 (for example, the top end of the colloid portion 321) is located at the first position, the positioning portion 3a of the positioning column 32 extends to the outside of the first sliding hole 112a. When the positioning portion 3a of the positioning column 32 is located at the second position, the positioning portion 3a of the positioning column 32 is located inside the first sliding hole 112a.

[0138] In addition, the number of the first sliding holes 112 a corresponds to the number of the first positioning members 3 .

[0139] Optionally, see Figure 5 As shown, the seat body 1 is provided with a first mounting hole 112 b. The first mounting hole 112 b is used to accommodate at least a part of the structure of the cylinder 31.

[0140] The first mounting hole 112b may be communicated with the first sliding hole 112a, and the first mounting hole 112b may be located below the first sliding hole 112a.

[0141] In addition, the second inner wall 112 ba (curved structure wall) in the seat body 1 for enclosing and forming the first mounting hole 112 b may be provided with threads, that is, the second inner wall 112 ba may be threadedly connected to the outer wall of the cylinder 31 .

[0142] In addition, the number of the first mounting holes 112 b corresponds to the number of the first positioning members 3 .

[0143] Optionally, see Figure 3-Figure 7As shown, the seat body 1 is provided with a third passage 13, the third passage 13 includes a first section 131 and at least two second sections 132, the first section 131 is connected with at least two second sections 132, the end of the first section 131 away from the second section 132 is a fifth port 1311, the end of the second section 132 away from the first section 131 is a sixth port 132a, the fifth port 1311 is used to communicate with the air source device, and the sixth port 132a extends to the pressing position 111a. The air source device can put the third passage 13 in a negative pressure state to generate a negative pressure adsorption effect on the diaphragm placed in the pressing position 111a, so that the diaphragm can still remain motionless relative to the pressing position 111a without being positioned by the first positioning member 3, thereby improving the accuracy of the fitting position between the diaphragm and the workpiece. Secondly, at least two second sections 132 in a negative pressure state can produce a negative pressure adsorption effect on at least two different parts of the diaphragm, and the reliability of the diaphragm being positioned at the pressing position 111a is higher, thereby better improving the accuracy of the fitting position between the diaphragm and the workpiece. Furthermore, the connection structure of "connecting a first section 131 to an air source device" has the advantages of quick assembly and quick disassembly.

[0144] The first section 131 may include at least one of a columnar hole, a cubic cavity, and a bent hole. Similarly, the second section 132 may include at least one of a columnar hole, a cubic cavity, and a bent hole.

[0145] In addition, due to different sectional positions, Figure 3-Figure 5 It is mainly used to show the first section 131 of the third passage 13 and the second section. Figure 6-Figure 7 Mainly used to display the first section 131 of the third passage 13, comprehensive Figure 3-Figure 7 , this article also provides Figure 8 A brief schematic diagram of the third passage 13 is shown to facilitate the clarification of the gas path of the third passage 13 .

[0146] In other embodiments (not shown in the figures), the seat body 1 may also be provided with a plurality of independent third passages 13 , each third passage 13 is a single passage, and the air source device may include a plurality of interfaces, each interface being connected to a corresponding third passage 13 .

[0147] Optionally, see Figure 3-Figure 8As shown, the seat body 1 includes a detachably connected bearing member 11 and a first adapter member 12, the bearing member 11 has a press-fit position 111a, and the first adapter member 12 is detachably connected to the cover body 2. The first section 131 is arranged on the first adapter member 12, and the second section 132 is arranged on the bearing member 11. A sinking groove 122 is arranged at one end of the first adapter member 12 facing the bearing member 11, and the sinking groove 122 encloses to form a groove space 1312. The first section 131 includes at least part of the groove space 1312, and the groove space 1312 is connected to at least two second sections 132. For diaphragms of different structures or different sizes, users can replace bearing members 11 of different structures or different sizes. Although the position of the second section 132 relative to the groove space 1312 is changed and the number of the second sections 132 is changed, since the area of ​​the cross section of the groove space 1312 perpendicular to the direction Z is larger than the area of ​​the cross section of the second section 132 perpendicular to the direction Z, the groove space 1312 can still be connected to at least two second sections 132, so that the film assembly 10 of this embodiment can still adsorb films of different structures or different sizes. Therefore, the film assembly 10 of this embodiment has the advantage of high universality.

[0148] The first adapter 12 may be installed with at least two carriers 11 to have at least two pressing positions 111 a.

[0149] In addition, the bearing member 11 may be provided with the first sliding hole 112a and the first mounting hole 112b described above. The first adapter member 12 may be provided with the first passage 121 described above.

[0150] Furthermore, the detachable connection between the carrier 11 and the first adapter 12 facilitates the assembly of the cylinder 31 inside the seat body 1 .

[0151] Optionally, the bearing member 11 may include a first bearing portion 111 and a second bearing portion 112, the first adapter 12 is detachably connected to the second bearing portion 112, the second bearing portion 112 is detachably connected to the first bearing portion 111, and the first bearing portion 111, the second bearing portion 112 and the first adapter 12 are stacked. The first bearing portion 111 has a pressing position 111a, and the second bearing portion 112 is provided with a first sliding hole 112a and a first mounting hole 112b. The material of the first bearing portion 111 may be a material with relatively low hardness such as rubber, plastic, etc., so as to reduce the possibility of the first bearing portion 111 squeezing and damaging the diaphragm and the workpiece. The second bearing portion 112 may be detachably connected to the second positioning member 14 described above.

[0152] The first bearing part 111 may be provided with a first through hole 111b, and the second bearing part 112 may be provided with a second sliding hole 112c. The seat body 1 may also include a support tube 15, which extends outward from the second sliding hole 112c, and is passed through the first through hole 111b until the support tube 15 extends to the plane where the pressing position 111a is located or a position higher than the plane where the pressing position 111a is located, and the third inner wall 112ca (curved surface structure wall) in the second bearing part 112 for enclosing and forming the second sliding hole 112c is slidably connected to the support tube 15. The seat body 1 also includes a first elastic member 16, and the first adapter 12 supports the bottom of the support tube 15 through the first elastic member 16. When the diaphragm is pressed against the top of the support tube 15 by the workpiece, the support tube 15 slides along the direction Z, and the first elastic member 16 is compressed and deformed, so that the first elastic member 16 generates an elastic force in the direction opposite to the direction Z on the support tube 15, so that the support tube 15 applies a force in the direction opposite to the direction Z to the bottom of the diaphragm, so that the diaphragm and the workpiece can be closely attached. In particular, since the area of ​​the end surface of the support tube 15 is smaller than the bearing area of ​​the pressing position 111a, the flatness of the end surface of the support tube 15 is easy to be higher than the flatness of the pressing position 111a, and the support tube 15 can more reliably press any part of the adhesive film of the diaphragm against the workpiece, so as to reduce the possibility of deformation of the diaphragm due to negative pressure adsorption, thereby reducing the possibility of partial failure of the diaphragm to be attached to the workpiece or partial failure of the diaphragm to be attached to the workpiece flatly. Therefore, the working reliability of the film attachment assembly 10 of the embodiment of the present application is higher. The number of support tubes 15 provided corresponds to the number of second sections 132 provided.

[0153] Please refer to Fig. 9 As shown, the support tube 15 may also be provided with a second through hole 1511, and the second through hole 1511 has an air inlet 1511a and an air outlet 1511b. The second through hole 1511 may serve as at least part of the second section 132 described above, the air inlet 1511a serving as the sixth port 132a, and the air outlet 1511b communicating with the groove space 1312 of the first section 131.

[0154] Please refer to Fig. 9 As shown, the support tube 15 may include a tube body 151 and a first step 152. The tube body 151 is provided with the second through hole 1511 described above, and the first step 152 is arranged around the tube body 151. Figure 5 As shown, the second bearing portion 112 includes a second step 112d, and the first step 152 and the second step 112d are limitedly matched to limit the support tube 15 from being separated from the bearing member 11 along the direction opposite to the Z direction.

[0155] In other embodiments (not shown in the figure), the support tube 15 can be replaced by a support member with a through groove, and the through groove is arranged along the extension direction of the support member (a direction parallel to the direction Z). The space enclosed by the through groove is connected to the first through hole 111b, and the two can form the second section 132 described above.

[0156] In other embodiments (not shown in the figures), the seat body 1 may not include the support tube 15 and the first elastic member 16, and the second sliding hole 112c and the first through hole 111b are connected to each other, and the two may constitute the second section 132 described above.

[0157] Please refer to Figure 5 As shown, the bottom wall of the sink 122 is a stepped structure, so that the groove space 1312 can be divided into a first space 1312a and a second space 1312b, and the second space 1312b surrounds the first space 1312a. Among them, the first space 1312a is used to communicate with the second section 132. The seat body 1 can also include a third sealing ring 17, and the third sealing ring 17 can be placed in the second space 1312b. The first adapter 12 can be sealed and connected to the carrier 11 through the third sealing ring 17 to improve the sealing degree of the air path between the first section 131 and the second section 132. Therefore, the working reliability of the film assembly 10 is high, and the energy consumption of the air source device is also low.

[0158] Please refer to Figure 5 As shown, the bottom wall of the sink 122 is further provided with a second mounting hole 123 , which is a blind hole and is used to locate and accommodate the bottom of the first elastic member 16 .

[0159] In other embodiments, the carrier 11 may be an integral part, and the carrier 11 may be provided with only two through holes, one of which may be equivalent to the second section 132, and the other may be equivalent to the first sliding hole 112a and the first mounting hole 112b.

[0160] Optionally, see Figure 1 As shown, the film sticking assembly 10 further includes a locking member 4, which is rotatably connected to the base 1, and can move to a loose position and a locked position relative to the base 1. When the locking member 4 is in the loose position, the locking member 4 has no limiting effect on the cover 2, and the cover 2 can be separated from the base 1. When the locking member 4 is in the locked position, the locking member 4 is pressed against the end of the cover 2 that is away from the base 1, so that the cover 2 can reliably press the workpiece against the film at the pressing position 111a.

[0161] Please refer to Figure 10-11As shown, the locking member 4 may include a first connecting rod 41 and a second connecting rod 42. The first connecting rod 41 is rotatably connected to the cover body 2, and the second connecting rod 42 is rotatably connected to the first connecting rod 41. The user may first operate the first connecting rod 41 to rotate relative to the cover body 2 around the rotation axis O1 so that the second connecting rod 42 is close to the cover body 2, and the user may then operate the second connecting rod 42 to rotate relative to the first connecting rod 41 around the rotation axis O2 so that the eccentric wheel rim 421 of the second connecting rod 42 abuts against the end of the cover body 2 away from the seat body 1. The user continues to operate the second connecting rod 42 to rotate so that the eccentric wheel rim 421 slides relative to the cover body 2, and accordingly, the contact position of the eccentric wheel rim 421 and the cover body 2 is changed from the first contact portion 421a to the second contact portion 421b. Under the condition that the first connecting rod 41 is stationary relative to the cover body 2, the rotation axis O2 is also relatively stationary. Since the distance between the first contact portion 421a and the rotation axis O2 is smaller than the distance between the second contact portion 421b and the rotation axis O2, the squeezing force between the eccentric rim 421 and the cover body 2 gradually increases during the process of the contact position between the eccentric rim 421 and the cover body 2 changing from the first contact portion 421a to the second contact portion 421b. Accordingly, the pressure applied by the cover body 2 to the workpiece also gradually increases, so that the workpiece and the diaphragm can fit tightly. When the contact position between the eccentric rim 421 and the cover body 2 is located at the second contact portion 421b, the static friction between the eccentric rim 421 and the cover body 2 is relatively large, that is, the eccentric rim 421 and the cover body 2 can achieve self-locking, and the user does not need to manually press the cover body 2 continuously, and the user's operation intensity is relatively low.

[0162] There are at least two locking members 4 .

[0163] In other embodiments (not shown in the figure), the locking member 4 can be a threaded member, and the cover body 2 is threadedly connected to the base body 1 through the threaded member. The user can rotate the threaded member to make the cover body 2 press the workpiece against the diaphragm located on the base body 1.

[0164] Optionally, see Fig.12 As shown, the cover body 2 includes a cover body 21, a second adapter 22, a pressing portion 23, a second elastic member 24 and a handle 25. The handle 25 is connected to the cover body 21, and the cover body 21 is slidably connected to the second adapter 22. The cover body 21 is also connected to the second adapter 22 through the second elastic member 24, and the second adapter 22 and the pressing portion 23 are detachably connected. The user can grasp the handle 25 to move the cover body 2, and the user can connect the locking member 4 to the end of the cover body 21 that is away from the seat body 1, and use the locking member 4 to apply pressure to the cover body 21, so that the pressing portion 23 presses the workpiece against the diaphragm located on the seat body 1. The second elastic member 24 plays a buffering role, reducing the possibility of the workpiece being squeezed and damaged by the cover body 2.

[0165] Among them, for workpieces with different structures or different sizes, the user can replace the pressing part 23 with different structures or different sizes. Therefore, the cover body 2 has the advantage of high universality.

[0166] In addition, the number of the second adapters 22 and the number of the pressing portions 23 are both at least two, so as to adapt to at least two pressing positions 111 a.

[0167] In a second aspect, an embodiment of the present application provides a film sticking device, the film sticking device comprising: Fig.13 The base 20 shown in Fig.13 The proximity sensor 30 shown and the film assembly 10 described above. The seat body 1 of the film assembly 10 is detachably connected to the base 20, and the proximity sensor 30 is arranged on the base 20. The proximity sensor 30 is used to sense whether the seat body 1 is installed on the base 20. Under the condition that the proximity sensor 30 senses that the seat body 1 has been installed on the base 20, the proximity sensor 30 can send a first signal, and the first signal is used to control the positioning portion 3a of the first positioning member 3 to move from the second position to the first position.

[0168] The first positioning member 3 may include an electric driving structure, and the electric driving structure may directly control the positioning portion 3a of the first positioning member 3 to move from the second position to the first position according to the first signal.

[0169] Alternatively, the film sticking device may include a controller, and after receiving the first signal, the controller may control the pneumatic structure or the electric structure to drive the positioning portion 3a of the first positioning member 3 to move from the second position to the first position. For example, if the first positioning member 3 includes the slidingly connected cylinder 31 and the positioning column 32 described above, after receiving the first signal, the controller may control the air source device to use air pressure to move the positioning column 32 from the second position to the first position.

[0170] Furthermore, the proximity sensor 30 may be a capacitive proximity sensor, an inductive proximity sensor, or a photoelectric proximity sensor.

[0171] In addition, the detachable connection between the seat body 1 and the base 20 may be a quick detachable connection, so that the user can quickly place the seat body 1 on the base 20, or the user can quickly remove the seat body 1 from the base 20. In detail, the base 20 has at least two guide limit portions 204, and the guide limit portions 204 may have guide surfaces, which can guide the seat body 1 to align with a preset position placed on the base 20. The at least two guide limit portions 204 can also limit the seat body 1 to limit the seat body 1 from deviating from the base 20.

[0172] Optionally, see Fig.14As shown, the base 20 is provided with a fourth passage 201, and the fourth passage 201 is connected to the first passage 121 of the base body 1 described above. The fourth passage 201 is used to be connected to the air source device. The air source device can change the air pressure of the fourth passage 201 and the air pressure of the first passage 121, so that the positioning portion 3a of the first positioning member 3 can be moved between the first position and the second position by utilizing the air pressure.

[0173] The seventh port 201 a of the fourth passage 201 is directly or indirectly connected to the gas source device, and the eighth port 201 b of the fourth passage 201 is connected to the first port 121 a of the first passage 121 .

[0174] Optionally, see Fig.15 As shown, the base 20 is provided with a fifth passage 202, which is connected to the third passage 13 of the seat body 1 described above, and is used to communicate with the gas source device, which can make the fifth passage 202 and the third passage 13 in a negative pressure state, so that the diaphragm can be negatively adsorbed to the seat body 1 by the negative pressure effect. Secondly, since the number of the first section 131 of the third passage 13 can be one, correspondingly, the number of the fifth passage 202 can also be one, and the connection structure of "for connecting one third passage 13 with one fifth passage 202" has the advantages of quick assembly and quick disassembly.

[0175] The ninth port 202 a of the fifth passage 202 is directly or indirectly connected to the gas source device, and the tenth port 202 b of the fifth passage 202 is connected to the fifth port 1311 of the third passage 13 .

[0176] Optionally, see Figure 14-15 As shown, the film sticking device also includes a first sealing ring 40, and the base 20 is sealed and connected to the seat body 1 through the first sealing ring 40. Under this setting, the air path between the fourth passage 201 and the first passage 121 is relatively sealed. Similarly, the air path between the fifth passage 202 and the third passage 13 is relatively sealed. The air source device can provide effective air pressure to the film sticking device, the working reliability of the film sticking device is high, and the energy consumption of the air source device is low.

[0177] In which, the base 20 can be provided with at least two annular mounting grooves 203, each mounting groove 203 can be installed with an annular first sealing ring 40, part of the annular mounting groove 203 and the annular first sealing ring 40 surround the seventh port 201a set in the fourth passage 201, and the other part of the annular mounting groove 203 and the annular first sealing ring 40 surround the ninth port 202a set in the fifth passage 202.

[0178] In addition, the first sealing ring 40 is raised relative to the surface of the base 20 facing the base body 1 , so that the first sealing ring 40 can reliably abut against the surface of the base body 1 facing the base 20 .

[0179] Any of the ports described above in this document has a respective length dimension in the direction Z, and the length dimensions of different ports may be the same or different.

[0180] The features described in the above content of this article, such as "port", "through hole", "sliding hole", "mounting hole", "positioning hole", "passage", "air inlet", "air outlet" and "space", are all spatial features (virtual features), not physical structural features included in the non-film-sticking device.

[0181] The working process of the film sticking device in the embodiment of the present application is as follows:

[0182] Step 1: Please refer to Fig.16 As shown, user a first places the seat body 1 on the base 20. After the proximity sensor 30 arranged on the base 20 senses that the seat body 1 has been placed on the base 20, the proximity sensor 30 sends a first signal to the controller. The controller that receives the first signal controls the air source device to perform a pressurization operation to increase the air pressure in the fourth passage 201, the air pressure in the first passage 121, and the air pressure in the second passage 311. The positioning portion 3a moves from the second position to the first position under the action of the air pressure.

[0183] Step 2: Please refer to Fig.17 As shown, user a places the diaphragm 50 on the seat 1, and the positioning hole 502a of the diaphragm 50 is penetrated by the positioning portion 3a, so that the diaphragm 50 is positioned by the positioning portion 3a.

[0184] Process 3: User a can manually operate the controller to control the air source device to perform decompression work, so that the air pressure in the fifth passage 202 and the air pressure in the third passage 13 are reduced, so that the diaphragm 50 is adsorbed to the seat body 1 by negative pressure.

[0185] Of course, a program may also be set so that after the positioning portion 3 a is located at the first position, the controller automatically controls the gas source device to perform a decompression operation so that the diaphragm 50 is adsorbed to the seat body 1 by negative pressure.

[0186] Step 4: Please refer to Fig.18 As shown, user a then manually controls the air source device to cancel the pressurization operation by operating the controller, so that the air pressure in the fourth passage 201, the air pressure in the first passage 121, and the air pressure in the second passage 311 are reduced, and the positioning portion 3a moves from the first position to the second position under the action of air pressure and gravity to cancel the positioning effect of the first positioning member 3 on the diaphragm 50. Since the diaphragm 50 is still adsorbed to the seat body 1 by the negative pressure, the diaphragm 50 is still immobile relative to the seat body 1.

[0187] Of course, a program can also be set, after the positioning portion 3a is located at the first position, after a set time has passed, the controller automatically controls the air source device to perform a decompression operation, so that the positioning portion 3a moves from the first position to the second position. Within the set time range, the user a can complete the process of placing the diaphragm 50 on the seat body 1 and having the diaphragm 50 positioned by the positioning portion 3a.

[0188] Step 5: Please refer to Fig.19 As shown, user a places the workpiece 60 on the diaphragm 50 , and positions the workpiece 60 by the second positioning member 14 .

[0189] Step 6: Please refer to Fig. 20 As shown, user a places the cover 2 on the base 1, which makes the locking member 4 still in the released position. Fig.21 As shown, the user moves the locking member 4 to the locking position to lock the cover body 2 and the base body 1 using the locking member 4 , so that the cover body 2 presses the workpiece 60 against the diaphragm 50 located on the base body 1 .

[0190] Step 7: Please refer to Fig. 22 As shown, user a separates the film assembly 10 with the film sheet 50 and the workpiece 60 from the base 20, and places the film assembly 10 with the film sheet 50 and the workpiece 60 on a first conveying device, which transfers the film assembly 10 with the film sheet 50 and the workpiece 60 to another user b.

[0191] During the process of transferring the film assembly 10 with the film 50 and the workpiece 60, the film 50 and the workpiece 60 are still in a pressed state, so that the film 50 and the workpiece 60 can be reliably bonded. The time length of pressing the film 50 and the workpiece 60 is greater than or equal to the time length of transfer, and the transfer time length can range from 20 seconds to 40 seconds. Accordingly, the time length of pressing the film 50 and the workpiece 60 can also range from 20 seconds to 40 seconds, specifically 20 seconds, 25 seconds, 30 seconds, 35 seconds or 40 seconds.

[0192] During the process of transferring the film laminating assembly 10 with the film sheet 50 and the workpiece 60, the user a can also use another film laminating assembly 10 to perform the above process 1 to process 7 to press another film sheet 50 and another workpiece 60 together. Therefore, the work efficiency of the user a is higher.

[0193] After another user b receives the film sheet 50 and the workpiece 60, the film assembly 10 is disassembled to separate the film sheet 50 and the workpiece 60. Fig.23The workpiece 60 and the film 50 that are bonded together are taken out from the film assembly 10, and then the base material 502 of the film 50 is torn off, so that the adhesive film 501 of the film 50 is attached to the workpiece 60. User b places the disassembled film assembly 10 on the second conveying device, and the second conveying device then conveys the disassembled film assembly 10 to user a, so that user a uses the disassembled film assembly 10 to perform the above process 1 to process 7. User b places the disassembled film assembly 10 on the second conveying device, and the second conveying device then conveys the disassembled film assembly 10 to user a, so that user a uses the disassembled film assembly 10 to perform the above process 1 to process 7. Fig.24 The workpiece 60 with the adhesive film 501 is placed on the third transport device, and the third transport device transports the workpiece 60 with the adhesive film 501 to another location.

[0194] It can be seen from the above content that the structural setting and working process setting of the film pasting device in the embodiment of the present application can improve the film pasting efficiency.
