Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0023] Please see Figure 1 This application provides a film-applying device 100, which includes a feeding assembly 10, a feed assembly 20 disposed near the feeding assembly 10, a transfer assembly 30 disposed on one side of the feeding assembly 10, and two sets of film-applying assemblies 40 respectively connected to the transfer assembly 30. The film-applying device 100 can use the two sets of film-applying assemblies 40 to respectively pick up films in opposite directions and adjust the films to the same direction to apply the adjusted films to a preset area of ​​the workpiece, eliminating the need for manual film application and thus improving film-applying efficiency. The workpiece can be a mobile phone or tablet computer, and the film can be a release film.

[0024] To facilitate understanding and explanation of the embodiments of this application, a three-dimensional coordinate system has been established in some of the accompanying drawings, with the first direction being... Figure 1 The Z-axis direction shown is... Figure 2 The direction shown is that the linkage 441 points towards the adsorbent 442, and the second direction is... Figure 1 The Y-axis direction shown is... Figure 1 The extension direction of the feeding assembly 10 shown is, in the third direction, ... Figure 1 The X-axis direction shown is... Figure 2 The lifting component 41 shown points in the direction of the rotating drive component 43, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0025] Please see Figure 1 The feeding assembly 10 is located on one side of the feeding assembly 20. The feeding assembly 10 is configured to provide a tape with multiple sets of films attached, each set of films including two films, and the two films are oriented in opposite directions. The feeding assembly 10 can be any feeding element, feeding body, or similar feeding part capable of providing a tape with multiple sets of films attached.

[0026] Please see Figure 1The feed assembly 20 is disposed on one side of the feed assembly 10 and configured to convey multiple workpieces to a predetermined area. The multiple workpieces are in the same direction, and the predetermined area is the location where a film-coating operation is performed on the workpieces. In this embodiment, the feed assembly 20 can be any feed section, feed body, or similar feed belt that conveys multiple workpieces.

[0027] Please see Figure 1 The transfer assembly 30 includes a first transfer member 31 disposed on one side of the supply assembly 20, a second transfer member 32 perpendicularly connected to the first transfer member 31, and a third transfer member 33 perpendicularly connected to the second transfer member 32. The first transfer member 31 is disposed along a first direction and connected to the two sets of film-applying assemblies 40 respectively; the second transfer member 32 is disposed along a second direction and connected to the first transfer member 31; and the third transfer member 33 is disposed along a third direction and connected to the second transfer member 32. In this embodiment, the first transfer member 31, the second transfer member 32, and the third transfer member 33 are all servo slides.

[0028] Thus, through the above configuration, the transfer component 30, in cooperation with the first transfer member 31, the second transfer member 32 and the third transfer member 33, drives the film application component 40 to move in three-dimensional space, thereby improving the range of motion and flexibility of the film application component 40, making the film application device 100 adaptable to different types of workpieces and films, thereby improving the stability and applicability of film application.

[0029] Please see Figure 1 and Figure 2 There are two sets of film application components 40, and the two sets of film application components 40 are respectively connected to the first transfer member 31 of the transfer component 30. Each set of film application components 40 includes a lifting member 41 connected to the first transfer member 31, a support member 42 connected to the lifting member 41, a rotation drive member 43 disposed on the support member 42, an adsorption member 44 connected to the rotation drive member 43, a fixing member 45 connected to the lifting member 41, a limiting member 46 connected to the support member 42, and an elastic member 47 abutting between the limiting member 46 and the fixing member 45.

[0030] The lifting member 41 is connected to the first transfer member 31 and the support member 42 respectively. The rotary drive member 43 is located on the support member 42 and connected to the adsorption member 44. The adsorption members 44 of the two sets of film-applying assemblies 40 are configured to adsorb two films in opposite directions in the same set of films, and rotate to a preset direction under the drive of the corresponding rotary drive member 43, thereby adjusting the two films to the same direction so that the transfer assembly 30 and the lifting member 41 cooperate to drive the two adsorption members 44 to attach the films to two adjacent workpieces. The fixing member 45 is generally U-shaped and connected to one side of the lifting member 41. The fixing member 45 has a receiving groove 451 on the side facing the adsorption member 44, and a placement groove 452 communicating with the receiving groove 451 is opened on the groove wall of the receiving groove 451. The limiting member 46 is generally rod-shaped and moves through the receiving groove 451 along the X-axis and is connected to the support member 42. The limiting member 46 has a receiving groove 461 on the side near the placement groove 452. The two ends of the elastic member 47 are respectively inserted into the placement groove 452 and the receiving groove 461. The elastic member 47 elastically abuts against the limiting member 46 and the fixing member 45, and the limiting member 46 compresses the elastic member 47 against the groove wall of the receiving groove 451. In this embodiment, the rotary drive member 43 is a motor and the elastic member 47 is a spring.

[0031] Thus, through the above configuration, the adsorption members 44 of the two sets of film-applying components 40 respectively adsorb two films facing opposite directions within the same set of films, and rotate to a preset direction under the drive of the corresponding rotation drive member 43, thereby adjusting the two films to the same direction. No manual adjustment of the film orientation is required. The transfer component 30 then drives the adsorption member 44 to move above the workpiece, and the lifting member 41 drives the adsorption member 44 to move closer to the workpiece, so that the adsorption member 44 attaches the film to the preset area of ​​the workpiece, achieving rapid completion of the film-applying operation, avoiding manual application, and thus improving application efficiency. The adsorption member 44 attaches the film to the workpiece. When the film is applied, the support member 42 drives the limiting member 46 to compress the elastic member 47 to the fixing member 45, so that the adsorption member 44 drives the film to make flexible contact with the workpiece, preventing damage to the workpiece, thereby improving the film application accuracy and the quality of the workpiece; the elastic member 47 abuts between the placement groove 452 and the storage groove 461 to limit the elastic member 47, so that the elastic member 47 is always compressed or provided with elastic force in the first direction, ensuring that the elastic member 47 is stably compressed by the limiting member 46 when applying the film, and driving the limiting member 46 to reset after the film application is completed, thereby ensuring the stable operation of the film application assembly 40 and improving the film application stability.

[0032] Please see Figure 1 and Figure 2The lifting component 41 includes a lifting body 411 connected to the first transfer component 31, a connecting body 412 connected to the lifting body 411, and a guide body 413 connected to the connecting body 412. The lifting body 411 is connected to the end of the first transfer component 31 away from the second transfer component 32. The connecting body 412 is generally plate-shaped, and the guide body 413 is generally rod-shaped. The guide body 413 is located on the side of the connecting body 412 facing the support component 42 and is slidably connected to the support component 42. The guide body 413 is configured to guide the support component 42 to move the adsorption component 44 closer to the workpiece. In this embodiment, the lifting body 411 is a servo slide.

[0033] Thus, through the above configuration, the guide body 413 guides the movement direction of the support member 42, so that the support member 42 drives the adsorption member 44 to always move along the first direction, which is conducive to the adsorption member 44 accurately attaching the film to the workpiece, thereby improving the film application accuracy.

[0034] Please see Figure 2 The support member 42 includes a support body 421 connected to the lifting body 411 and a support body 422 connected to the support body 421. The support body 421 is generally plate-shaped and is slidably connected to the guide body 413, while also being connected to the lifting body 411. The support body 422 is generally plate-shaped and is located on the side of the support body 421 opposite to the guide body 413, and is perpendicularly connected to the support body 421. The support body 422 is connected to the rotary drive member 43 to support the rotary drive member 43.

[0035] Thus, through the above arrangement, the support body 421 and the support body 422 are vertically connected, forming a receiving space between the support body 421 and the support body 422 to accommodate the rotating drive component 43, thereby making the film application assembly 40 reasonably arranged to optimize the structure of the film application assembly 40.

[0036] Please see Figure 2 and Figure 3 The adsorption component 44 includes a linkage body 441 vertically connected below the rotary drive component 43 and an adsorption body 442 connected to the linkage body 441. The linkage body 441 is generally frame-shaped and movably passes through the support body 422 along a first direction and is connected to the rotary drive component 43. The adsorption body 442 is generally block-shaped and is located at the end of the linkage body 441 away from the rotary drive component 43 and is vertically connected to the linkage body 441. The side of the adsorption body 442 away from the rotary drive component 43 has multiple adsorption holes 4421. The multiple adsorption holes 4421 are evenly arranged and connected to an external air source. The multiple adsorption holes 4421 are configured as one of two membranes in the same group. The adsorption body 442 has a clearance groove 4422. The clearance groove 4422 is located on the side of the adsorption body 442 away from the rotary drive component 43 and is configured to avoid part of the workpiece.

[0037] Thus, by setting the linkage body 441 and the adsorption body 442 vertically connected, the structural layout of the adsorption component 44 is optimized, creating a clearance space between the linkage body 441 and the adsorption body 442. This allows the adsorption component 44 to avoid interference with the support component 42 and adjacent adsorption components when driven to rotate by the rotation drive component 43, thereby improving the stability of the film application. Furthermore, by providing multiple adsorption holes 4421 on the adsorption body 442, the number of adsorption points for the film is increased, ensuring stable adsorption of the film and preventing it from falling off during transfer, thus improving the adsorption stability of the adsorption component 44. Additionally, by providing clearance grooves 4422, the workpiece is partially obstructed during film application, preventing collisions between the workpiece and the adsorption body 442, further improving the stability of the film application.

[0038] Please see Figure 1 The film application device 100 further includes an image acquisition assembly 50, which includes a first image acquisition element 51 disposed on one side of the first transfer member 31, a second image acquisition element 52 disposed on one side of the supply member assembly 20, and a controller 53 electrically connected to the first image acquisition element 51 and the second image acquisition element 52. The first image acquisition element 51 is disposed near the supply member assembly 10 and located on one side of the first transfer member 31, and is configured to acquire an image of the film adsorbed by the adsorption member 44. The second image acquisition element 52 is disposed adjacent to the supply member assembly 20, and is configured to acquire an image of the workpiece provided by the supply member assembly 20. The controller 53 is electrically connected to the first image acquisition element 51, the second image acquisition element 52, the first transfer member 31, the second transfer member 32, and the third transfer member 33, respectively, and is configured to control the transfer member 30 to drive the two adsorption members 44 to attach two films of the same group to two adjacent workpieces. In this embodiment, both the first image sensor 51 and the second image sensor 52 are industrial cameras.

[0039] Thus, through the above settings, the first image sensor 51 acquires an image of the film adsorbed by the adsorption element 44, the second image sensor 52 acquires an image of the workpiece provided by the supply component 20, and the controller 53, based on the image of the first image sensor 51 and the image of the second image sensor 52, controls the transfer component 30 to drive the two adsorption elements 44 to attach the two films of the same group to the preset areas of the two adjacent workpieces, thereby improving the film application accuracy.

[0040] The working process of the above-mentioned film application device 100 is roughly as follows: First, the feeding assembly 10 provides a strip with multiple diaphragms attached, and the feeding assembly 20 conveys multiple workpieces to a predetermined area; Then, the adsorption members 44 of the two sets of film-applying components 40 adsorb two films with opposite directions in the same set of films respectively, and rotate to the preset direction under the drive of the corresponding rotation drive member 43, thereby adjusting the two films to the same direction without the need for manual adjustment of the film direction; Finally, the first image sensor 51 acquires an image of the film adsorbed by the adsorption element 44, and the second image sensor 52 acquires an image of the workpiece provided by the supply component 20. Based on the images of the first image sensor 51 and the second image sensor 52, the controller 53 controls the transfer component 30 to drive the two adsorption elements 44 to attach the two films of the same group to the preset areas above the two adjacent workpieces respectively. Then, the lifting element 41 drives the adsorption element 44 to move closer to the workpiece so that the adsorption element 44 attaches the film to the preset area of ​​the workpiece. No manual film application is required, thereby improving the film application efficiency.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
