[0037] like Figure 1-Figure 7 As shown, this embodiment provides an assembly tool with a flexible circuit board display screen, including a rear shell positioning seat 1, a display screen positioning plate 2, a lifting component 3 and a vacuum generator, one end of the rear shell positioning seat 1 has a positioning groove 5, the other end of the rear shell positioning seat 1 is fixedly connected to the lifting component 3, the lifting part of the lifting component 3 is hinged to the display screen positioning plate 2, and makes the display screen positioning plate 2 approach or move away from the rear shell positioning seat 1, the display screen positioning plate 2 has an adsorption hole on the side facing the rear shell positioning seat 1, and the vacuum generator is connected and communicated with the adsorption hole.

[0038] The display screen with flexible circuit board is positioned by adsorption with the display screen positioning plate through the vacuum generator, and the product back shell is placed in the positioning groove of the back shell positioning seat. The staff manually flips the display screen positioning plate until it is parallel to the back shell positioning seat. The horizontal position of the display screen with flexible circuit board and the product back shell is determined by the display screen positioning plate and the positioning groove. The flexible circuit board of the display screen with flexible circuit board is accurately aligned with the through holes of the product back shell one by one, and then the lifting assembly is driven to drive the display screen positioning plate and the flexible circuit board close to the back shell positioning seat, so that the flexible circuit board of the display screen on the display screen positioning plate passes through the through holes of the product back shell one by one. The operation is simple and effective, and it can effectively improve the production efficiency and stability of product quality.

[0039] Specifically, the display screen 11 with a flexible circuit board and the display screen positioning plate 2 are positioned by adsorption by a vacuum generator, that is, when the vacuum generator draws vacuum through the adsorption hole, the display screen 11 with a flexible circuit board is adsorbed, and the product rear shell 12 is engaged and positioned with the positioning groove 5.

[0040] Among them, Figure 2 As shown, four flexible circuit boards are fixed at intervals on one side of the flexible circuit board display screen 11, and one side of the product rear shell 12 has four through holes, and the four flexible circuit boards pass through the four through holes one by one.

[0041] On the basis of the above scheme, the lifting assembly 3 includes a fixed plate 301, a lifting plate 302, a sliding rod 303, a screw 304 and a handle 305, one end of the sliding rod 303 is fixedly connected to the fixed plate 301, the other end of the sliding rod 303 is fixedly connected to the rear shell positioning seat 1, the lifting plate 302 is slidably connected to the sliding rod 303, one end of the screw 304 rotates through the fixed plate 301 and the lifting plate 302 in turn, and is rotatably connected to the rear shell positioning seat 1, the screw 304 is threadedly connected to the lifting plate 302, the other end of the screw 304 is fixedly connected to the handle 305, and one end of the lifting plate 302 is hinged to the display screen positioning plate 2.

[0042] The staff rotates the handle 305 clockwise or counterclockwise, and the rotation of the handle 305 drives the rotation of the screw 304, and the rotation of the screw 304 drives the lifting plate 302 to move upward or downward along the slide bar 303 in the vertical direction, thereby driving the display screen positioning plate 2 away from or close to the rear shell positioning seat 1.

[0043] Optionally, there are one or more slide bars 303. Specifically, Figure 3 As shown, the lifting assembly 3 includes four sliding bars 303 , and the four sliding bars 303 are arranged at intervals along the circumference of the fixing plate 301 .

[0044] The screw rod 304 rotates through the middle of the fixed plate 301 and the lifting plate 302 in sequence, and when the staff rotates the handle 305, the balance of the entire device can be maintained.

[0045] In addition, the lifting plate 302 is a lifting part of the lifting assembly 3 .

[0046] Based on the above scheme, a plurality of magnets 6 are fixed at intervals at one end of the display screen positioning plate 2 close to the lifting plate 302, and a plurality of suction blocks 7 are fixed at one end of the lifting plate 302. The plurality of suction blocks 7 are attracted or separated with the plurality of magnets 6 in a one-to-one correspondence.

[0047] When the staff manually flips the display screen positioning plate 2 to be parallel to the rear shell positioning seat 1, multiple suction blocks 7 and multiple magnets 6 can press one end of the lifting plate 302 and one end of the display screen positioning plate 2 tightly to ensure the stability of the lifting plate 302 and the display screen positioning plate 2 in the vertical direction.

[0048] Specifically, Figure 2 As shown, four suction blocks 7 are fixed at intervals on one side of the lifting plate 302, and one end of the display screen positioning plate 2 has four magnets 6, and the four magnets 6 and the four suction blocks 7 are attracted or separated one by one.

[0049] On the basis of the above scheme, it also includes an elastic component 4, which includes a fixed block 401, two first screws 402, a spring 403, two second screws 405 and a limit block 404. The fixed block 401 is fixedly connected to the display screen positioning plate 2, and the limit block 404 is located on the side of the fixed block 401 facing the rear shell positioning seat 1. The two first screws 402 are arranged at intervals, and the two second screws 405 are arranged one-to-one with the two first screws 402. One end of the first screw 402 slides through the fixed block 401, and one end of the second screw 405 slides through the limit block 404 and is fixedly connected to the other end of the first screw 402. One end of the spring 403 abuts against the fixed block 401, and the other end of the spring 403 abuts against the limit block 404, and applies an elastic force to the limit block 404 to keep it away from the fixed block 401.

[0050] When the display screen 11 with a flexible circuit board on the display screen positioning plate 2 moves in the vertical direction to abut against the product back shell 12 of the back shell positioning seat 1, and the flexible circuit board passes through the through hole of the product back shell 12, the elastic component 4 is used to fit with the back shell positioning seat 1, buffer the collision between the display screen positioning plate 2 and the back shell positioning seat 1 when it descends, and make the display screen positioning plate 2 fit tightly with the back shell positioning seat 1, ensuring that the display screen 11 with a flexible circuit board and the product back shell 12 fit perfectly with zero gap, thereby improving product quality.

[0051] Specifically, two ends of the fixing block 401 are fixedly connected to the display screen positioning plate 2 by screws.

[0052] Among them, after the flexible circuit board with the flexible circuit board display screen 11 passes through the through hole of the product back shell 12, the lifting assembly continues to be driven, and the flexible circuit board display screen 11 is displaced downward in the vertical direction. At this time, the limit block 404 abuts against the back shell positioning seat 1, and the back shell positioning seat 1 exerts an upward force on the limit block 404 and the spring 403, so that the spring 403 is in a compressed state, and the first screw 402 and the second screw 405 slide upward in the vertical direction. As the display screen positioning plate 2 descends, the limit block 404 slides upward in the vertical direction, buffering the impact of the display screen positioning plate 2 on the back shell positioning seat 1, and making the display screen positioning plate 2 close to the back shell positioning seat 1, ensuring that the flexible circuit board display screen 11 and the product back shell 12 fit perfectly with zero gap.

[0053] On the basis of the above solution, the display screen positioning plate 2 is fixed with two elastic components 4 along the X-axis direction, and the display screen positioning plate 2 is fixed with two elastic components 4 along the Y-axis direction.

[0054] Elastic components 4 are arranged along the X-axis direction and the Y-axis direction to further buffer the collision between the display screen positioning plate and the rear shell positioning seat when the display screen positioning plate descends.

[0055] Optionally, elastic components 4 may be fixed at intervals around the display screen positioning plate 2 .

[0056] Specifically, the elastic component 4 is located on the outer side of the display screen 11 with a flexible circuit board.

[0057] On the basis of the above solution, the positioning groove 5 is a U-shaped groove penetrating through the end wall of one end of the rear shell positioning seat 1 .

[0058] The U-shaped groove facilitates positioning the product rear shell 12 on the rear shell positioning seat 1 .

[0059] Specifically, the size of the U-shaped groove corresponds to the size of the product rear shell 12 one by one.

[0060] On the basis of the above scheme, it also includes an air pipe interface 8, which is fixedly connected to the display screen positioning plate 2, one end of the air pipe interface 8 is connected to the adsorption hole, and the other end of the air pipe interface 8 is connected and connected to the vacuum generator.

[0061] By controlling the vacuum generator, the display screen 11 with the flexible circuit board can be adsorbed on the display screen positioning plate 2 or released from the display screen positioning plate 2 through the air pipe interface 8 .

[0062] On the basis of the above scheme, a foot valve 9 is further included. The other end of the air pipe interface 8 is connected to the vacuum generator through a connecting pipe, and the foot valve 9 is arranged on the connecting pipe.

[0063] The staff can control the pedal valve 9 according to the actual situation to connect or disconnect the connecting pipeline, so as to control the vacuum generator to adsorb, position or release the display screen 11 with a flexible circuit board.

[0064] On the basis of the above solution, it further comprises a tool identification plate 10 , and the tool identification plate 10 is fixed on the rear shell positioning seat 1 .

[0065] It is convenient for staff to identify the models of different tooling.

[0066] Specifically, the tool identification plate 10 may include information such as machine model, fixture name, production date, version, manufacturer and fixture code, so as to facilitate identification by the staff.

[0067] On the basis of the above solution, it further comprises a plurality of pulleys 13 , and the plurality of pulleys 13 are all fixedly connected to the rear shell positioning seat 1 .

[0068] The staff can move the tool to any position through the pulley 13 according to the actual situation.

[0069] Specifically, in this embodiment, there are four pulleys 13 , and the four pulleys 13 are respectively located around the bottom of the rear shell positioning seat 1 .

[0070] In this embodiment, when in use, first, the staff controls the foot valve 9 to connect the vacuum generator with the adsorption hole, and the display screen 11 with the flexible circuit board is adsorbed and positioned with the display screen positioning plate 2 through the vacuum generator, and the product rear shell 12 is placed in the positioning groove 5 in the rear shell positioning seat 1;

[0071] Secondly, the staff manually flips the display screen positioning plate 2 downward until it is parallel to the rear shell positioning seat 1, and matches the multiple magnets 6 at one end of the display screen positioning plate 2 with the multiple suction blocks 7 at one end of the lifting plate 302 one by one, ensuring that the lifting plate 302 and the display screen positioning plate 2 are on the same horizontal line. Then, the handle 305 is turned to drive the screw 304 to rotate, thereby driving the lifting plate 302 to move downward until the flexible circuit board with the flexible circuit board display 11 is aligned with the through hole of the product rear shell 12 one by one. Then, the handle 305 is continued to be turned to make the lifting plate 302 continue to move downward, so that the flexible circuit boards of the flexible circuit board display 11 pass through the through holes of the product rear shell 12 one by one, and the elastic component 4 is used to ensure that the display screen positioning plate 2 is in close contact with the rear shell positioning seat 1;

[0072] Finally, the staff controls the foot valve 9 again to disconnect the vacuum generator from the adsorption hole, and the adsorption hole returns to normal pressure, so that the flexible circuit board display screen 11 loses adsorption and separates from the display screen positioning plate 2. The assembly of the flexible circuit board display screen 11 and the product back shell 12 is completed, and the assembled product is placed in the designated area, and then the display screen positioning plate 2 is moved upward and turned over until it is perpendicular to the back shell positioning seat 1, so as to wait for the next set of flexible circuit board display screens 11 and product back shells 12 to be aligned and perforated.
