Description

Technical Field

[0001] This utility model relates to the field of mobile phone mid-frame lamination technology, and in particular to a mobile phone mid-frame lamination device. Background Technology

[0002] In the manufacturing process of mobile phone frames, after surface coating, a protective film is used to wrap the side edges of the product to prevent scratches or contamination of the high-gloss surface during subsequent processing. Especially in the precision engraving process, the film-coated product needs to be placed on a precision engraving fixture for positioning. However, the coating and precision engraving processes are usually handled by different production departments, with a 10-15 day material turnover and storage interval between them. During this process, the protective film may experience insufficient adhesion or peeling at both ends due to decreased adhesion or environmental factors, leading to a decrease in positioning accuracy on the precision engraving fixture and consequently, processing defects. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mobile phone frame pressing device capable of re-pressing a peeling protective film onto the mobile phone frame.

[0004] A mobile phone frame pressing device according to an embodiment of the present invention includes a frame, a positioning fixture, and a pressing mechanism. The positioning fixture is slidably mounted on the frame along a first horizontal direction and is used to position the mobile phone frame. The pressing mechanism is mounted on the frame and is located on one side of the positioning fixture. The pressing mechanism includes a first pressing member, a second pressing member, and a contouring limiting block. The first pressing member and the second pressing member are distributed along a vertical direction, and a pressing area is formed between the first pressing member and the second pressing member. The contouring limiting block is provided with a contouring groove, and the contouring groove and the pressing area are distributed along the first horizontal direction. Under the action of external force, the positioning fixture can slide along the first horizontal direction so that the side frame of the mobile phone frame passes through the contouring groove and the pressing area in sequence, and the groove wall of the contouring groove initially presses the opposite ends of the protective film on the side frame to the front end face and the back end face of the mobile phone frame, respectively, and the first pressing member and the second pressing member completely press the protective film onto the front end face and the back end face, respectively.

[0005] A mobile phone mid-frame pressing device according to an embodiment of the present utility model has at least the following technical effects: In the mobile phone mid-frame lamination device of this application, the mobile phone mid-frame is first placed on the positioning fixture, and the positioning fixture is used to position the mobile phone mid-frame to prevent the position of the mobile phone mid-frame from moving during the subsequent lamination process, thereby affecting the lamination effect. Then, the positioning fixture is driven by external force to slide along the first horizontal direction on the frame, so that the positioning fixture drives the mobile phone mid-frame to slide along the first horizontal direction. This causes the side frame of the mobile phone mid-frame to pass through the contouring groove and the pressing area of ​​the contouring limiting block in sequence along the first horizontal direction. The protective film on the side frame is initially pressed onto the front end face and the back end face of the mobile phone mid-frame by the groove wall of the contouring groove.

[0022] The following is for reference. Figure 1 and Figure 2 A detailed description of a mobile phone mid-frame pressing device according to an embodiment of the present invention will be provided.

[0023] refer to Figure 1 and Figure 2 According to an embodiment of the present invention, a mobile phone mid-frame lamination device includes a frame 100, a positioning fixture 200, and a lamination mechanism 300. The positioning fixture 200 is slidably mounted on the frame 100 along a first horizontal direction and is used to position the mobile phone mid-frame. The lamination mechanism 300 is mounted on the frame 100 and is located on one side of the positioning fixture 200. The lamination mechanism 300 includes a first pressing member 310, a second pressing member 320, and a contouring limiting block 330. The first pressing member 310 and the second pressing member 320 are distributed along a vertical direction, and the first pressing member 310 and the second pressing member 320 are... A pressing area 300a is formed between the pressing parts 320, and a contouring groove 330a is provided on the contouring limiting block 330. The contouring groove 330a and the pressing area 300a are distributed along the first horizontal direction. The positioning fixture 200 can slide along the first horizontal direction under the action of external force, so that the side frame of the mobile phone frame passes through the contouring groove 330a and the pressing area 300a in sequence, and the groove wall of the contouring groove 330a initially presses the opposite ends of the protective film on the side frame to the front end face and the back end face of the mobile phone frame, respectively. The first pressing part 310 and the second pressing part 320 completely press the protective film on the front end face and the back end face, respectively.

[0024] In the mobile phone mid-frame lamination device of this application, the mobile phone mid-frame is first placed on the positioning fixture 200. The positioning fixture 200 positions the mobile phone mid-frame to prevent the position of the mobile phone mid-frame from moving during the subsequent lamination process, thereby affecting the lamination effect. Then, the positioning fixture 200 is driven by external force to slide along the first horizontal direction on the frame 100, so that the positioning fixture 200 drives the mobile phone mid-frame to slide along the first horizontal direction. This causes the side frame of the mobile phone mid-frame to pass through the contour groove 330a and the pressing area 300a of the contour limiting block 330 in sequence along the first horizontal direction. The groove wall of the contour groove 330a is used to initially press the opposite ends of the protective film on the side frame onto the front end face and the back end face of the mobile phone mid-frame. Then, the first pressing member 310 and the second pressing member 320 are used to completely press the protective film onto the front end face and the back end face, respectively. As can be seen from the above, this application achieves pre-positioning of the protective film through the contoured groove 330a, avoiding the offset caused by direct pressing. Then, the first pressing member 310 and the second pressing member 320 tightly press the protective film onto the mobile phone frame, further improving the pressing efficiency. This application can effectively solve the problem of the protective film on the mobile phone frame lifting after long-term placement.

[0025] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the film pressing mechanism 300 further includes a first driving structure 340, which is connected to the first pressing member 310 and the second pressing member 320 respectively, and is used to drive the first pressing member 310 and the second pressing member 320 to move closer or further apart in the vertical direction. It can be understood that by driving the two pressing members to move towards or away from each other in the vertical direction through the first driving structure 340, the gap of the pressing area 300a is adjusted, thereby achieving the pressing of protective films on the side frames of mobile phone frames of different thicknesses.

[0026] Specifically, the first drive structure 340 adopts a finger cylinder, and the two grippers of the finger cylinder are respectively connected to the first pressing member 310 and the second pressing member 320, and can drive the first pressing member 310 and the second pressing member 320 to move closer or further away from each other at the same time.

[0027] like Figure 1 and Figure 2As shown, in some embodiments, the film pressing mechanism 300 further includes a second driving structure 350, which is drivenly connected to the contouring limiting block 330 and is used to drive the contouring limiting block 330 closer to or further away from the positioning fixture 200, so that the side frame enters or leaves the contouring groove 330a. It can be understood that when the positioning fixture 200 approaches the molding mechanism, the second driving structure 350 drives the contouring limiting block 330 to approach the positioning fixture 200 along a second horizontal direction, thereby allowing the side frame of the phone frame to accurately extend into the contouring groove 330a of the contouring limiting block 330. Then, the groove wall of the contouring groove 330a initially presses the opposite ends of the protective film on the side frame onto the front and back end faces of the phone frame, respectively. After the entire protective film on the side frame is pressed, the second driving structure 350 drives the contouring limiting block 330 away from the positioning fixture 200 along a second horizontal direction to avoid the contouring limiting block 330 interfering with subsequent processes.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, the pressing mechanism 300 further includes a slide 360, a first driving structure 340 and a contouring limiting block 330 respectively disposed on the slide 360, and a second driving structure 350 drivenly connected to the slide 360 ​​and used to drive the slide 360 ​​to move closer to or away from the positioning fixture 200. It can be understood that by disposing of both the first driving structure 340 and the contouring limiting block 330 on the slide 360, and then driving the slide 360 ​​to move via the second driving structure 350, the slide 360 ​​can drive the first pressing member 310, the second pressing member 320 and the contouring limiting block 330 as a whole to move closer to or away from the positioning fixture 200, thus achieving the coordinated forward and backward movement of the pressing mechanism 300.

[0029] refer to Figure 1 and Figure 2 In some embodiments of this utility model, both the first pressing member 310 and the second pressing member 320 are rollers, which are rotatably arranged about a horizontal axis. It is understood that by using rollers for both the first pressing member 310 and the second pressing member 320, the friction between the first pressing member 310 and the second pressing member 320 and the protective film on the side frame can be effectively reduced, thus preventing wear on the protective film. Specifically, the rollers rotate about a horizontal axis parallel to the second horizontal direction.

[0030] refer to Figure 1 and Figure 2In some embodiments of this utility model, two pressing mechanisms 300 are provided, respectively located on opposite sides of the positioning fixture 200 in the second horizontal direction, which intersects with the first horizontal direction. It can be understood that the two pressing mechanisms 300 are symmetrically installed on both sides of the positioning fixture 200 in the second horizontal direction. When the positioning fixture 200 slides, the two side frames of the middle frame in the second horizontal direction sequentially enter the corresponding pressing mechanism 300 to complete the pressing. The simultaneous processing of multiple sides through the two pressing mechanisms effectively improves the pressing efficiency. Furthermore, the symmetrical arrangement of the two pressing mechanisms 300 balances the force on the positioning fixture 200 and reduces sliding resistance.

[0031] Specifically, the second horizontal direction is perpendicular to the first horizontal direction.

[0032] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the positioning fixture 200 is provided with a positioning post 210, which is used to position the middle frame of the mobile phone. It can be understood that by providing the positioning post 210 on the positioning fixture 200 and passing the positioning post 210 through the positioning hole on the middle frame of the mobile phone, the middle frame of the mobile phone can be positioned quickly and accurately.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, an adsorption element 220 is provided on the positioning fixture 200, which is used to adsorb and fix the mobile phone frame. It is understood that by providing the adsorption element 220 on the positioning fixture 200 to adsorb the mobile phone frame, the mobile phone frame can be stably attached to the positioning fixture 200, thereby effectively preventing the possibility of the mobile phone frame lifting during movement and affecting the film pressing effect. Specifically, the adsorption element 220 is a suction cup and is connected to a vacuum generator.

[0034] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the mobile phone mid-frame pressing device further includes a driving mechanism 400. The driving mechanism 400 is disposed on the frame 100 and is drivenly connected to the positioning fixture 200. The driving mechanism 400 is used to drive the positioning fixture 200 to slide along a first horizontal direction. It can be understood that after the mobile phone mid-frame is placed in the positioning fixture 200, the driving mechanism 400 drives the positioning fixture 200 to slide along the first horizontal direction, and the side frame of the mobile phone mid-frame passes through the contoured groove 330a and the pressing area 300a distributed along the first horizontal direction in sequence, thereby completing the automatic pressing of the protective film on the side frame of the mobile phone, further improving the pressing efficiency.

[0035] Specifically, the drive mechanism 400 includes a motor and a slide rail. The slide rail extends along a first horizontal direction, and the motor drives the positioning fixture 200 to move along the slide rail so that the positioning fixture 200 can slide stably along the first horizontal direction.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the mobile phone frame laminating device further includes a feeding mechanism. The frame 100 is provided with a feeding position and a laminating position. A drive mechanism 400 drives the positioning fixture 200 to move between the feeding position and the laminating position. The feeding mechanism is used to feed the mobile phone frame to the positioning fixture 200 located at the feeding position. It can be understood that initially, the positioning fixture 200 is located at the feeding position. The feeding mechanism places the mobile phone frame from the tray onto the positioning fixture 200. Then, the drive mechanism 400 drives the positioning fixture 200 to slide along the first horizontal direction to the laminating position. The laminating mechanism 300 then presses the protective film on the side frame of the mobile phone frame. Finally, the drive mechanism 400 transports the positioning fixture 200 back to the feeding position for unloading. This fully automated process reduces manual intervention, enables continuous production, and greatly improves laminating efficiency.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
