[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1

[0023] Please see Figures 1 to 3This utility model provides a technical solution: an IC prefabrication bracket for a mobile phone display screen, including a fixture platform 1, a contoured groove 2, an IC clearance groove 3, and a quick clamp 4. A foot 12 near a corner is fixedly connected to the bottom of the fixture platform 1, and an anti-slip pad 121 is adhered to the bottom of the foot 12. The contoured groove 2 and the quick clamp 4 are both located on the top of the fixture platform 1, with the quick clamp 4 positioned on one side of the contoured groove 2. The functions of the IC clearance groove 3, the contoured groove 2, and the quick clamp 4 are the same as those of the structures mentioned in the patent documents in the background art, and will not be repeated in this application.

[0024] In this technical solution, the top of the fixture platform 1 is provided with a stepped surface 11 located on one side of the contour groove 2. The height of the stepped surface 11 is lower than the height of the contour groove 2. An annular turntable 5 is provided on the stepped surface 11. The upper surface of the annular turntable 5 is provided with IC clearance grooves 3 evenly distributed around the circumference. Positioning posts 6 are fixedly provided on the upper surface of the annular turntable 5 at both ends of the IC clearance grooves 3. One IC clearance groove 3 corresponds to two positioning posts 6. The structure and function of the positioning posts 6 are the same as those in the patent documents mentioned in the background book, that is, to position the IC adhesive tape. When the annular turntable 5 rotates, it will drive the IC adhesive tape on it to be in the pressing position in turn. It should be noted that during the pressing process of the quick clamp 4, the operator can pre-install the IC adhesive tape on the annular turntable 5 through the positioning posts 6, thereby effectively utilizing the pressing pause time of the quick clamp 4, so that after pressing, the annular turntable 5 can be directly rotated to switch to other IC adhesive tapes and quickly enter the pressing position.

[0025] The quick clamp 4 is provided with a mounting base 41, which is located inside the ring of the annular turntable 5. The top of the stepped surface 11 is fixedly connected to a support sleeve 111 fitted inside the annular turntable 5. The support sleeve 111 and the annular turntable 5 are rotatably connected. In specific implementation, a bearing can be installed between the support sleeve 111 and the annular turntable 5.

[0026] Furthermore, a control assembly 7 for controlling the rotation of the annular turntable 5 is provided on the fixture platform 1.

[0027] Specifically, the control assembly 7 includes a worm gear 71 and a worm wheel 72. The worm gear 71 is rotatably connected to the fixture platform 1, and the worm wheel 72 is fixedly mounted on the bottom of the annular turntable 5 and meshes with the worm gear 71. When the worm gear 71 rotates, it uses the meshing action to drive the worm wheel 72 to rotate, which in turn drives the annular turntable 5 to rotate.

[0028] Furthermore, a drive shaft 711 is fixedly connected to one end of the worm gear 71, and a handle 7111 is fixedly connected to one end of the drive shaft 711. An elastic telescopic limit pin 8 is provided on the stepped surface 11. The lower surface of the annular turntable 5 is provided with limit holes 51 that cooperate with the free end of the elastic telescopic limit pin 8 and are evenly distributed in the circumference. The function of the limit holes 51 is to precisely limit the position of the IC clearance slot 3. When in use, the annular turntable 5 rotates until the free end of the elastic telescopic limit pin 8 is inserted into one of the limit holes 51. At this time, one IC clearance slot 3 on the annular turntable 5 is in the pressing position. After pressing is completed, the elastic telescopic limit pin 8 is controlled to retract, and then the annular turntable 5 is controlled to rotate to switch the adjacent IC clearance slot 3 to the pressing position.

[0029] The elastic telescopic limiting pin 8 includes a guide sleeve 81, a support spring 82 located inside the guide sleeve 81, and an actuating rod 83 with one end sleeved inside the guide sleeve 81. The bottom of the guide sleeve 81 is fixedly connected to the stepped surface 11, and the top of the actuating rod 83 is inserted into the limiting hole 51. During use, a ball bearing can be set on the top of the actuating rod 83 to reduce contact friction. A pressing rod 831 is welded to one side of the actuating rod 83. The pressing rod 831 is an operating component for controlling the retraction of the actuating rod 83.

[0030] Example 2

[0031] See Figure 3 The difference between this embodiment and embodiment 1 is that one end of the worm 71 is fixedly connected to a transmission shaft 711, and a control motor 9 is fixedly connected to the stepped surface 11. The output shaft of the control motor 9 is fixedly connected to one end of the transmission shaft 711. Thus, the rotation of the worm 71 is controlled by the control motor 9, eliminating the need for the elastic telescopic limit pin 8, which facilitates the use of an external controller to achieve intelligent control of the rotation of the annular turntable 5.

[0032] Working principle: Before use, multiple IC adhesive strips are installed on the annular turntable 5 via positioning pins 6. During use, the worm gear 71 is rotated manually via lever 7111. The worm wheel 72 rotates, causing the annular turntable 5 to rotate. One of the IC adhesive strips will approach the contoured groove 2. When the top of the action lever 83 is inserted into the limiting hole 51, the annular turntable 5 cannot rotate. At the same time, one of the IC adhesive strips is in the position of being bonded to the FPC. The operator can operate to control the IC adhesive strip to be bonded to the FPC. Then, the quick clamp 4 is manually operated to press the FPC to prevent it from lifting up. After pressing, the quick clamp 4 is reset, and then the OLED hard screen can be removed. Then, the pressing lever 831 is manually pushed down, and the annular turntable 5 is rotated to switch to the next IC adhesive strip in the pressing position. Then, the manual bonding and pressing operations are performed again. During the pressing and holding process of the quick clamp 4, the operator can use this time gap to add more IC adhesive strips to the annular turntable 5.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
