DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The following describes in detail a technical solution for providing a retractable portable mirror according to various embodiments of the present invention in conjunction with the accompanying drawings.

[0026] Reference Figures 1 to 6 As shown, an embodiment of the present invention provides an adjustable chip fixing fixture for chip processing equipment, which is used for positioning chips in the chip processing production process, such as chip detection, welding, testing and other processes, and specifically includes: an upper seat 4 and a rotatable adjustable lower pressure piece 9. A first square hole 6 is provided on the top of the upper seat 4, and a second square hole 7 is provided on the bottom of the upper seat 4. The first square hole 6 is connected to the second square hole 7. The channel formed by the first square hole 6 and the second square hole 7 is used for specific operations of detection, welding, testing and other processes. Two groups of circular transverse holes 8 are provided on the side of the upper seat 4. The two groups of circular transverse holes 8 are distributed on the side positions parallel to one group of the second square holes 7. The rotatable adjustable lower pressure piece 9 is rotatably installed on the inner side of the circular transverse hole 8.

[0027] Specifically, when the fixing fixture is used, it is installed on a driving component that can move up and down. During the downward movement of the upper seat 4, the rotatable adjustable pressing member 9 is driven to move downward, and the fixing part designed on the side of the chip is pressed down by the action part on the rotatable adjustable pressing member 9, thereby achieving the chip being pressed and fixed.

[0028] Specifically, through the specific design of the rotatable adjustable down-pressing member 9, it includes a rotatable adjustable tensioning shaft 901, a rotating body 905 is provided on the sliding sleeve of the tensioning shaft 901, and a number of connecting parts distributed in a circular array are fixedly provided on the outside of the rotating body 905. A down-pressing member 906 is fixedly installed at each connecting part. The action parts of the down-pressing members 906 corresponding to the several connecting parts have different vertical distances from the tensioning shaft 901, and the rotating body 905 and the tensioning shaft 901 are fixedly connected by transverse screws.

[0029] Specifically, before the fixing jig is used to press down and fix the chip, the pulling shaft 901 is rotated and adjusted so that the pulling shaft 901 drives the rotating body 905 and the pressing piece 906 to rotate together, and one of the pressing pieces 906 is pointed downward (for pressing down the chip). It is selected according to the edge position of the chip, which can adapt to the clamping and fixing of chips of different sizes. The user can also loosen the horizontal screw and slide the position of the rotating body 905 on the pulling shaft 901 to make the action part of the pressing piece 906 correspond to the clamping point designed on the side edge of the chip (the clamping position designed on the side of the circuit board); when in use, based on the above two adjustment methods, it can adapt to the fixation of chips of different sizes and different clamping points, improve the versatility of the fixing jig, reduce the frequency of replacing jigs or repositioning in the actual production process, improve production efficiency, and reduce the production cost of chips.

[0030] In one embodiment, a lower seat 1 , a bottom support member 3 and a lifting assembly 5 are also designed.

[0031] A chip slot 2 is provided at the top of the lower seat 1. The chip slot 2 can be designed to be larger to meet the placement requirements of most chips, and two groups of symmetrically arranged bottom support members 3 are installed on the inner side of the chip slot 2. A positioning slot 305 is provided at the top of the bottom support member 3 and close to the inner side of the chip slot 2. The actual size of the bottom support member 3 is adapted to the outer edge size of the chip. The chip is actually supported by the bottom support member 3. Through the designed positioning slot 305, the chip can be better positioned. The lifting component 5 is fixedly installed on the side of the lower seat 1, and the telescopic end of the lifting component 5 is fixedly installed on the upper seat 4.

[0032] Specifically, after determining the size of the chip and the position of the clamping point, the user replaces the bottom support 3 of the required size and adjusts the rotatable adjustable lower pressure member 9 to ensure that the produced chip can be fixedly clamped. The robot grabs the chip and places it on the positioning groove 305 on the bottom support 3. The lifting component 5 drives the upper seat 4 to move downward. During the downward movement of the upper seat 4, the rotatable adjustable lower pressure member 9 is driven to move downward. The action part on the rotatable adjustable lower pressure member 9 presses down the fixed part designed on the side of the chip, thereby pressing and fixing the chip.

[0033] In one embodiment, the bottom support member 3 includes a platform 301 , a rubber pad 304 , a first rotating shaft 303 , and a tail plate 302 .

[0034] Specifically, a tail plate 302 is fixedly provided at the tail of the block 301, and the tail plate 302 is rotatably connected to the side wall of the chip slot 2 through the first rotating shaft 303. An installation step opening is provided at the bottom of the block 301, and a rubber pad 304 is fixedly connected to the inside of the installation step opening. A positioning groove 305 is provided at the top of the block 301.

[0035] like Figure 4、 Figure 6 As shown in the figure, under the elastic support of the rubber pad 304, the block 301 is tilted upward as a whole, so that the distance between the positioning grooves 305 of the two bottom support members 3 is increased, which can adapt to the small error of the robot in placing the chip. In the subsequent fixing link, the block 301 is pressed downward and rotated, and the side of the positioning groove 305 rotates inward to perform secondary positioning of the chip 10.

[0036] Specifically, the lifting assembly 5 includes a telescopic member 502, a vertical frame 504, and a connecting plate 503. A connecting frame 501 is fixedly installed on the side of the lower seat 1. The connecting frame 501 is designed as a T-shaped structure. The side of the connecting frame 501 is fixedly connected to the telescopic member 502. The bottom end of the vertical frame 504 is fixedly connected to the top flange of the upper seat 4. A threaded head is provided at the top of the vertical frame 504, and a step is formed between the threaded head and the vertical frame 504. The top telescopic end of the telescopic member 502 is fixedly connected with a connecting plate 503. The connecting plate 503 is sleeved on the threaded head, and the connecting plate 503 is fixed to the threaded head by relying on a tightening nut 505 threadedly installed on the threaded head.

[0037] Specifically, an upward step is formed at the intersection of the first square hole 6 and the second square hole 7. If the fixed fixture is used for the detection link (visual inspection), a transparent glass protection sheet can be installed at the step position at the intersection of the first square hole 6 and the second square hole 7 to protect the chip.

[0038] Specifically, side plates 903 are sleeved on both ends of the tensioning shaft 901 and located on the outside of the upper seat 4. Nuts are threadedly connected at both ends of the tensioning shaft 901 and located on the outside of the side plates 903. After the nuts at both ends are tightened, the tensioning shaft 901 is fixed by the clamping force of the tension. A hexagonal rod segment 902 is provided on the tensioning shaft 901, and a hexagonal hole is opened on the side plate 903 to cooperate with the hexagonal rod segment 902. The design of the hexagonal rod segment 902 can prevent the tensioning shaft 901 from rotating relative to the side plate 903.

[0039] When adjusting the rotation of the tension shaft 901, it is necessary to loosen the nuts at both ends, then move the side plates 903 outward so that the side plates 903 slide away from the hexagonal rod segments 902 on the tension shaft 901, rotate the tension shaft 901, and then reinstall the side plates 903 and nuts.

[0040] Specifically, a limiting block 904 is fixedly connected to the outer side of the upper seat 4 and located on the side of the side plate 903. The limiting block 904 is used to limit the rotation of the side plate 903 to prevent the side plate 903 from rotating together with the tension shaft 901.

[0041] Specifically, the pressing pieces 906 corresponding to the several connecting parts are: a first pressing piece 906a, a second pressing piece 906b, and a third pressing piece 906c. The first pressing piece 906a, the second pressing piece 906b, and the third pressing piece 906c all have connecting plates corresponding to the connecting parts. The active part of the first pressing piece 906a is located on the inner side of the connecting plate of the first pressing piece 906a, the active part of the second pressing piece 906b is located on the middle side of the connecting plate of the second pressing piece 906b, and the active part of the third pressing piece 906c is located on the outer side of the connecting plate of the third pressing piece 906c. The first pressing piece 906a, the second pressing piece 906b, and the third pressing piece 906c are all made of metal, and are covered with a plastic layer on the outside to ensure rigidity during the clamping process, and they need to protect the chip clamping part.

[0042] When in use, the pull shaft 901 is rotated to adjust one of the pressing members 906 to the working position. Specifically, one of the first pressing member 906a, the second pressing member 906b, and the third pressing member 906c is adjusted to the working position according to the outline size of the chip 10 (see FIG. 1 ). Figure 6 The second hold-down member 906b is shown in a horizontal position and is in a working position).

[0043] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
