Description

Technical Field

[0001] This utility model relates to a positioning device, specifically a chip positioning mechanism. Background Technology

[0002] A chip is a silicon wafer containing integrated circuits, used to perform calculations and process tasks. Chips are used in many areas of our daily lives and are a core cornerstone of high-end manufacturing. After manufacturing, chips need to be flashed with software; this process is called programming or firmware. Programming requires specialized equipment. Besides the precise positioning required during programming, other processes such as coding, OCR recognition, and information writing detection also require precise chip positioning. Therefore, chip positioning is extremely important in the programming process.

[0003] Existing positioning mechanisms primarily push the chip in two mutually perpendicular directions to the designated position, thus completing the positioning process. Furthermore, because the chip needs to be pushed in two mutually perpendicular directions, two sets of active driving mechanisms are required, resulting in a complex structure and high cost. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a chip positioning mechanism that has the advantages of simple structure and low cost.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A chip positioning mechanism includes a positioning base, a chip holder, an X-axis positioning component, and a Y-axis positioning component;

[0007] The positioning base is provided with a mounting groove;

[0008] The chip holder is fixedly installed in the middle of the mounting slot of the positioning base;

[0009] The X-axis positioning component includes two X-axis positioning sliders and an X-axis driving component for moving the two X-axis positioning sliders. The two X-axis positioning sliders are arranged opposite to each other in the mounting slot, and the chip holder is located between the two X-axis positioning sliders.

[0010] The Y-axis positioning component includes two Y-axis positioning sliders, which are disposed opposite to each other in the mounting slot, and the chip holder is located between the two Y-axis positioning sliders. The Y-axis positioning sliders are connected to the X-axis positioning sliders through a linkage structure. When the X-axis driving component drives the X-axis positioning sliders to move in the X direction, the linkage structure causes the Y-axis positioning sliders to move in the Y direction.

[0011] In a preferred embodiment of this utility model, the linkage structure includes a linkage sliding groove and a linkage sliding part. The linkage sliding groove is formed on the X-axis positioning slider, and the opening of the linkage sliding groove is not parallel to the X-axis. The linkage sliding part is disposed on the Y-axis positioning slider and engages with the linkage sliding groove. With this structure, when the X-axis positioning slider moves in the X-axis direction, the linkage sliding part of the Y-axis positioning slider is subjected to an inclination force from the linkage sliding groove. This inclination force can be decomposed into an X-axis component and a Y-axis component. The X-axis component cancels out the movement of the X-axis positioning slider, while the Y-axis component drives the Y-axis positioning slider to move in the Y-axis, thus positioning the chip in the Y-axis direction.

[0012] In a preferred embodiment of this invention, an X-axis sliding guide structure is provided between the X-axis positioning slider and the mounting groove. This X-axis sliding guide structure includes an X-axis sliding guide portion and an X-axis sliding guide groove. The X-axis sliding guide portion is disposed on the X-axis positioning slider, and the X-axis sliding guide groove is formed on the side wall of the mounting groove. This structure provides a guide for the sliding of the X-axis positioning slider, resulting in more precise positioning.

[0013] In a preferred embodiment of this utility model, the Y-axis positioning slider is connected to the positioning base via a Y-axis sliding guide structure. This Y-axis sliding guide structure includes a Y-axis sliding guide rod and a Y-axis sliding guide hole. The Y-axis sliding guide rod passes through the Y-axis sliding guide hole, one end of which is fixedly connected to the Y-axis positioning slider, and the other end of which is provided with a limiting head that limits movement outside the Y-axis sliding guide hole. This structure provides a guide for the sliding of the Y-axis positioning slider, resulting in more precise positioning.

[0014] In a preferred embodiment of this utility model, the chip holder is provided with a negative pressure hole, which is connected to a negative pressure channel.

[0015] In a preferred embodiment of this invention, the X-axis driving assembly includes an X-axis driving cylinder, X-axis driving arms, and push blocks. The X-axis driving cylinder is a double-rod cylinder. Two X-axis driving arms are provided and arranged opposite each other, with each arm fixedly connected to a telescopic rod of the double-rod cylinder. Two push blocks are provided and respectively mounted on the two X-axis driving arms. With this structure, driven by the X-axis driving cylinder, the two X-axis driving arms, carrying the two push blocks, approach the two X-axis positioning sliders, pushing them towards each other, thereby pushing the chip on the chip holder to the designated position and achieving X-axis positioning.

[0016] Furthermore, the bottom of the mounting groove is provided with a spring groove, and the X-direction positioning slider is provided with a spring action part extending into the spring groove;

[0017] The X-axis drive assembly also includes an X-axis return spring, which is disposed in the spring groove. The two ends of the X-axis return spring abut against the spring action portion of the X-axis positioning slider and the inner wall of the spring groove, respectively. With this structure, when the X-axis drive cylinder drives the X-axis positioning slider for X-axis positioning, the X-axis return spring is compressed and stores energy. When the X-axis drive cylinder drives the push block to reset, the X-axis return spring releases its potential energy to drive the X-axis positioning slider to reset.

[0018] In a preferred embodiment of this invention, the mounting groove is provided with two pins arranged along the X-axis, and the chip holder is located between the two pins. This limits the movement of the two X-axis positioning sliders, preventing excessive sliding and thus avoiding damage to the chip.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The chip positioning mechanism of this utility model has a linkage structure. When the X-axis driving component drives the X-axis positioning slider to move in the X direction, the linkage structure causes the Y-axis positioning slider to move in the Y direction. Therefore, the Y-axis driving component can be eliminated, the structure is simpler, and the cost is lower. Attached Figure Description

[0024] Figure 4 This is a three-dimensional structural diagram of the positioning base of this utility model. Detailed Implementation

[0025] To enable those skilled in the art to fully understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] Combination Figures 1-4 The chip positioning mechanism of this embodiment includes a positioning base 1, a chip holder 2, an X-axis positioning component, and a Y-axis positioning component; the positioning base 1 is provided with a mounting groove 101; the chip holder 2 is fixedly disposed in the middle position of the mounting groove 101 of the positioning base 1, wherein the chip holder 2 is provided with a negative pressure hole, which is connected to a negative pressure channel.

[0027] Combination Figures 1-4 The X-axis positioning component includes two X-axis positioning sliders 3 and an X-axis driving component for moving the two X-axis positioning sliders 3. The two X-axis positioning sliders 3 are disposed opposite each other in the mounting groove 101, and the chip holder 2 is located between the two X-axis positioning sliders 3. The Y-axis positioning component includes two Y-axis positioning sliders 4, which are disposed opposite each other in the mounting groove 101, and the chip holder 2 is located between the two Y-axis positioning sliders 4. The Y-axis positioning sliders 4 are connected to the X-axis positioning sliders 3 through a linkage structure. When the X-axis driving component drives the X-axis positioning sliders 3 to move in the X direction, the linkage structure causes the Y-axis positioning sliders 4 to move in the Y direction.

[0028] Combination Figures 1-4 The linkage structure includes a linkage sliding groove 301 and a linkage sliding part 401. The linkage sliding groove 301 is formed on the X-direction positioning slider 3, and the opening of the linkage sliding groove 301 is not parallel to the X-direction. The linkage sliding part 401 is disposed on the Y-direction positioning slider 4 and fits in the linkage sliding groove 301. With the above structure, when the X-direction positioning slider 3 moves in the X direction, the linkage sliding part 401 of the Y-direction positioning slider 4 will be subjected to the tilting force of the linkage sliding groove 301. This tilting force can be decomposed into an X-direction component and a Y-direction component. The X-direction component cancels out the movement of the X-direction positioning slider 3, while the Y-direction component drives the Y-direction positioning slider 4 to move in the Y direction, thereby positioning the chip in the Y direction.

[0029] Combination Figures 1-4 An X-axis sliding guide structure is provided between the X-axis positioning slider 3 and the mounting groove 101. This X-axis sliding guide structure includes an X-axis sliding guide portion 302 and an X-axis sliding guide groove 102. The X-axis sliding guide portion 302 is disposed on the X-axis positioning slider 3, and the X-axis sliding guide groove 102 is formed on the side wall of the mounting groove 101. This structure provides a guide for the sliding of the X-axis positioning slider 3, resulting in more precise positioning.

[0030] Combination Figures 1-4 The Y-axis positioning slider 4 is connected to the positioning base 1 via a Y-axis sliding guide structure. This Y-axis sliding guide structure includes a Y-axis sliding guide rod 5 and a Y-axis sliding guide hole 103. The Y-axis sliding guide rod 5 passes through the Y-axis sliding guide hole 103. One end of the Y-axis sliding guide rod 5 is fixedly connected to the Y-axis positioning slider 4, and the other end of the Y-axis sliding guide rod 5 is provided with a limiting head that limits its movement outside the Y-axis sliding guide hole 103. This structure provides a guide for the sliding of the Y-axis positioning slider 4, resulting in more precise positioning.

[0031] Combination Figures 1-4The X-axis drive assembly includes an X-axis drive cylinder 6, X-axis drive arms 7, and push blocks 8. The X-axis drive cylinder 6 is a double-rod cylinder. Two X-axis drive arms 7 are provided and arranged opposite each other, with each arm fixedly connected to a telescopic rod of the double-rod cylinder. Two push blocks 8 are provided and respectively mounted on the two X-axis drive arms 7. Through this structure, driven by the X-axis drive cylinder 6, the two X-axis drive arms 7, carrying the two push blocks 8, approach the two X-axis positioning sliders 3, pushing them towards each other, thereby pushing the chip on the chip holder 2 to the designated position, achieving X-axis positioning.

[0032] Furthermore, the bottom of the mounting groove 101 is provided with a spring groove 104, and the X-axis positioning slider 3 is provided with a spring action part 303 extending into the spring groove 104; the X-axis drive assembly also includes an X-axis return spring 9, which is disposed in the spring groove 104, and its two ends abut against the spring action part 303 of the X-axis positioning slider 3 and the inner wall of the spring groove 104, respectively. With the above structure, when the X-axis drive cylinder 6 drives the X-axis positioning slider 3 for X-axis positioning, the X-axis return spring 9 is compressed and stores energy; when the X-axis drive cylinder 6 drives the push block 8 to reset, the X-axis return spring 9 releases potential energy to drive the X-axis positioning slider 3 to reset.

[0033] Combination Figures 2-3 The mounting groove 101 is provided with two pins 10, which are arranged along the X-direction, and the chip holder 2 is located between the two pins 10. In this way, the two X-direction positioning sliders 3 can be limited to prevent them from sliding excessively and thus damaging the chip.

[0034] Combination Figures 1-4 The working principle of the above-mentioned chip positioning mechanism is as follows:

[0035] During operation, the chip is first placed on the chip holder 2. Then, driven by the X-axis drive cylinder 6, the two X-axis drive arms 7, carrying two push blocks 8, approach the two X-axis positioning sliders 3 respectively, pushing the two X-axis positioning sliders 3 towards each other. This causes the two push blocks 8 to simultaneously approach the chip, thereby pushing the chip on the chip holder 2 to the designated position, achieving X-axis positioning. At the same time, as the X-axis positioning slider 3 moves in the X direction, the linkage sliding part 401 of the Y-axis positioning slider 4 is subjected to the tilting force of the linkage sliding groove 301. This tilting force can be decomposed into an X-axis component and a Y-axis component. The X-axis component cancels out the movement of the X-axis positioning slider 3, while the Y-axis component drives the Y-axis positioning slider 4 to move in the Y direction, thus positioning the chip in the Y direction.

[0036] Furthermore, during the positioning process described above, the X-axis reset spring 9 is compressed and stores energy; after positioning is completed, the X-axis drive cylinder 6 drives the push block 8 to reset, and at the same time, the X-axis reset spring 9 releases potential energy to drive the X-axis positioning slider 3 and the Y-axis positioning slider 4 to reset; thus, one round of chip positioning is completed.

[0037] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
