The camera is taken in the correct position. The fine-tuning drive assembly adjusts the position of the phone's middle frame based on the photo's position information, so that the phone's middle frame precisely corresponds to the bottom of the screen. After the alignment is completed, the positioning cylinder drives the positioning column to retract upward, or a hole for accommodating the positioning column is set on the carrier so that the positioning column does not collide with the carrier when pressing down. Then, under the action of the flip drive assembly, the flip pressure plate moves downward. As the flip pressure plate presses on the carrier, the screen is pressed tightly against the phone's middle frame and assembled. During the downward pressing process, the buffer device allows the carrier to move downward a certain distance, acting as a buffer to prevent damage to the workpiece during assembly. After assembly is completed, the adsorption platform no longer adsorbs the screen, the screen assembly assembly resets, and the assembled phone workpiece can be removed. The advantage of this design is that the carrier and positioning column are used to perform preliminary positioning of the phone's middle frame and screen respectively, and then the photo positioning assembly is used to accurately position both, resulting in higher assembly accuracy of the phone's middle frame and screen.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 5 As shown, a mobile phone folding screen alignment assembly device includes a frame 1, an installation middle plate 2, a fine-tuning drive component 3, a middle frame clamping platform 4, a flip drive component 5, a screen assembly component 6 and a photo positioning component 7. The installation middle plate 2 is fixed to the middle of the frame 1, and an air avoidance hole is opened on the installation middle plate 2. The fine-tuning drive component 3 is fixed to the frame 1, and the lower end of the middle frame clamping platform 4 is fixed to the power output end of the fine-tuning drive component 3. The upper end of the middle frame clamping platform 4 is passed through the air avoidance hole. The flip drive component 5 is fixed to the rear side of the installation middle plate 2, one end of the screen assembly is fixed to the power output end of the flip drive component 5, and the photo positioning component 7 is fixed to the frame 1 and corresponds to the top of the middle frame clamping platform 4;

[0023] The middle frame clamping platform 4 includes a buffer device 41, a mounting bracket 42, a carrier 43 and a pressing device 44. The lower end of the buffer device 41 is fixed to the power output end of the fine-tuning drive assembly 3, the mounting bracket 42 is fixed above the buffer device 41, the carrier 43 is fixed to the middle of the mounting bracket 42, and the pressing device 44 is fixed on the mounting bracket 42 with the pressing end corresponding to the upper part of the carrier 43. The pressing devices 44 are provided in multiple groups and are evenly distributed on the periphery of the carrier 43.

[0024] The screen assembly component 6 includes a rocker arm 61, a flip pressure plate 62, an adsorption platform 63, a positioning cylinder 64 and a positioning column 65. One end of the rocker arm 61 is fixed to the power output end of the flip drive component 5. Two groups of rocker arms 61 are arranged. The left and right ends of the flip pressure plate 62 are respectively fixed on the two groups of rocker arms 61. The adsorption platform 63 is fixed on the flip pressure plate 62 and the front end is the adsorption end. The positioning cylinder 64 is fixed on the flip pressure plate 62. The positioning column 65 is fixed to the power output end of the positioning cylinder 64 and passes through the adsorption platform 63. The front end of the positioning column 65 corresponds to the front side of the adsorption platform 63. The positioning cylinder 64 and the positioning column 65 are arranged in two groups longitudinally on the left side of the adsorption platform 63, and the positioning cylinder 64 and the positioning column 65 are arranged in two groups transversely on the lower side of the adsorption platform 63.

[0025] The mobile phone folding screen alignment assembly equipment of this design is used to automatically assemble the mobile phone middle frame and screen, and place the mobile phone middle frame on the carrier 43. Since the mobile phone middle frame has a folding structure, the middle frame may be tilted and uneven when placed on the carrier 43. At this time, the outer periphery of the mobile phone middle frame is pressed down by the pressing device 44 to make the mobile phone middle frame flat on the carrier 43. The pressing device 44 is reset, and then the screen is placed on the screen assembly component 6. At this time, the flip pressure plate 62 is in a vertical state. The screen is placed on the positioning column 65 on the lower side and in contact with the positioning column 65 on the left side, thereby preliminarily positioning the screen. Then, the adsorption carrier 43 adsorbs the screen, and under the action of the flip drive component 5, the flip pressure plate 62 is flipped to a horizontal position. The photo positioning component 7 takes a photo of the position of the screen and the mobile phone middle frame, and fine-tunes The drive assembly 3 adjusts the position of the phone's middle frame based on the position information of the photo, so that the phone's middle frame accurately corresponds to the bottom of the screen. After the alignment is completed, the positioning cylinder 64 drives the positioning column 65 to retract upward, or a hole is set on the carrier 43 to accommodate the positioning column 65, so that the positioning column 65 will not collide with the carrier 43 when pressing down. Then, under the action of the flip drive assembly 5, the flip pressure plate 62 moves downward. As the flip pressure plate 62 presses on the carrier 43, the screen is pressed tightly against the phone's middle frame and assembled. During the downward pressing process, the buffer device 41 allows the carrier 43 to move downward a certain distance, acting as a buffer to prevent damage to the workpiece during assembly. After assembly is completed, the adsorption platform 63 no longer adsorbs the screen, the screen assembly assembly 6 is reset, and the assembled phone workpiece can be removed. The advantage of this design is that the mobile phone middle frame and screen are initially positioned by the carrier 43 and the positioning column 65 respectively, and then the photo positioning assembly 7 accurately positions both, making the assembly accuracy of the mobile phone middle frame and screen higher.

[0026] The fine-tuning drive assembly 3 includes an X-axis drive component 31, a Y-axis drive component 32 and a rotation drive component 33. The X-axis drive component 31 is fixed on the frame 1, the Y-axis drive component 32 is fixed to the power output end of the X-axis drive component 31, the rotation drive component 33 is fixed to the power output end of the Y-axis drive component 32, and the lower end of the buffer device 41 is fixed to the power output end of the rotation drive component 33.

[0027] The fine-tuning drive assembly 3 is used to adjust the position and angle of the middle frame clamping platform 4. The X-axis drive component 31 drives the Y-axis drive component 32 to move left and right, the Y-axis drive component 32 drives the rotation drive component 33 to move forward and backward, and the rotation drive component 33 drives the buffer device 41 to rotate a certain angle on the horizontal plane.

[0028] The buffer device 41 includes a first mounting plate 411, a second mounting plate 412, a third mounting plate 413, a first vertical slide 414, a second vertical slide 415, an elastic component 416 and a pressure sensor 417. The first mounting plate 411 is fixed to the power output end of the rotation drive component 33, the second mounting plate 412 corresponds to the top of the first mounting plate 411, the lower end of the first vertical slide 414 is fixed to the first mounting plate 411, the upper end of the second vertical slide 415 is fixed to the second mounting plate 412, and the first vertical slide 414 is fixed to the second mounting plate 412. The straight slide 414 and the second vertical slide 415 are slidably connected. The first vertical slide 414 and the second vertical slide 415 are each provided with four groups and correspond to the four sides of the first mounting plate 411 respectively. The upper and lower ends of the elastic component 416 are respectively fixed on the second mounting plate 412 and the first mounting plate 411. The third mounting plate 413 corresponds to the top of the second mounting plate 412. The pressure sensor 417 is fixed between the second mounting plate 412 and the third mounting plate 413. The mounting bracket 42 is fixed above the third mounting plate 413.

[0029] During the assembly of the screen and the middle frame of the mobile phone, the second mounting plate 412 and the third mounting plate 413 both move downward, and the elastic component 416 is compressed, thereby buffering the assembly process. The first vertical slide 414 and the second vertical slide 415 slide relative to each other, so that the second mounting plate 412 descends vertically and steadily. During the descent, the pressure sensor 417 is used to detect the downward pressure. When the pressure reaches a specific value, the equipment stops to prevent the ring workpiece from being pressed.

[0030] In this design, a pressure maintaining component 8 is also included. The pressure maintaining component 8 includes a clamping cylinder 81 and a pressure block 82. The clamping cylinder 81 is fixed above the installation middle plate 2. Two groups of clamping cylinders 81 are set and correspond to the left and right sides of the flip pressure plate 62 respectively. The pressure block 82 is fixed at the power output end of the clamping cylinder 81. The clamping cylinder 81 drives the pressure block 82 to rotate and press down.

[0031] After the flip driving assembly 5 drives the flip pressure plate 62 to press down on the carrier 43, the clamping cylinder 81 drives the pressure block 82 to rotate above the flip pressure plate 62 and press down on the flip pressure plate 62 to maintain pressure on the screen and improve assembly reliability.

[0032] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
