Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a chip fixing device for a chip scanner. Background Art

[0002] In today's technological landscape, chips, as core components of electronic devices, are crucial for performance and quality testing. A chip scanner is a device specifically designed for precise chip testing and analysis. It can quickly and accurately obtain a variety of chip information, such as circuit structure and performance parameters.

[0003] In early chip scanners, chip fixation was relatively simple. Typically, a simple mounting slot was set up on the scanner's workbench, and the chip was placed directly into the slot. The shape and size of the slot controlled the chip's position, securing it. This fixation method, to a certain extent, met the basic chip fixation requirements of chip scanners.

[0004] This traditional fixing method exposes a problem during use: the chip is placed in the installation slot and is not easy to take out. On the one hand, because the chip and the installation slot fit tightly, the friction between the two is large after the chip is placed in the installation slot, resulting in the staff needing to spend a lot of effort to remove the chip from the installation slot when the chip needs to be taken out. Especially for some miniaturized, high-precision chips, which are small in size and light in weight, they are more susceptible to damage from external forces during the removal process. On the other hand, in some scenarios where chips need to be frequently replaced for testing, this inconvenient fixing method greatly reduces work efficiency and increases the time cost of testing. Moreover, if the chip is stuck too tightly in the installation slot, forced removal may also cause damage to the installation slot of the chip scanner, affecting the service life of the equipment.

[0005] To solve these problems, researchers began to work on developing a new chip fixing device that can not only ensure the stability and accuracy of the chip during the operation of the scanner, but also facilitate the removal and replacement of the chip to meet the ever-evolving chip detection needs. Utility Model Content

[0006] Aiming at the problem that it is difficult to remove a chip after it is placed in a mounting groove in the prior art, the utility model proposes a chip fixing device for a chip scanner.

[0007] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0008] A chip fixing device for a chip scanner includes a base, an upper end surface of the base is provided with a chip placement cavity, the center position of the bottom wall of the chip placement cavity protrudes upward to form a mounting seat, the mounting seat is elongated, the left and right side walls of the mounting seat are in contact with the left and right inner walls of the chip placement cavity, the distance between the front and rear side walls of the mounting seat is smaller than the distance between the front and rear side walls of the chip placement cavity, and the height of the mounting seat is lower than the upper end surface of the base.

[0009] When in use, place the chip on the mounting seat. Since the mounting seat is set at the center of the bottom wall of the chip placement cavity, the chip can remain balanced on the mounting seat. When the chip needs to be removed, the chip is tilted to one side by hand or with tools, which makes it easier for the staff to remove the chip.

[0010] Preferably, a cavity is provided in the mounting seat, micropores communicating with the cavity are evenly provided on the upper end surface of the mounting seat, and an air extraction mechanism communicating with the cavity is also provided on the mounting seat.

[0011] In order to improve the stability of the chip on the mounting base, micropores are set on the mounting base, and air is pumped out through an exhaust mechanism to achieve the purpose of using the micropores to adsorb the chip, thereby better improving the stability of the chip on the mounting base.

[0012] Preferably, the exhaust mechanism includes an exhaust hole base having an exhaust hole connected to the cavity at the lower end surface, and an exhaust pipe is provided at the exhaust hole. The exhaust pipe extracts air from the cavity through the exhaust hole, so that the air pressure inside the cavity is lower than the external air pressure.

[0013] Preferably, a sealing groove is provided in the base which is staggered with the exhaust holes. The cross section of the sealing groove is rectangular and is arranged horizontally. A sealing plate which can move horizontally in the sealing groove is provided in the sealing groove. The sealing plate is used to control the opening and closing of the exhaust holes.

[0014] The opening and closing of the exhaust hole is controlled by moving the sealing plate in the sealing groove. When the chip needs to be taken out, the exhaust hole is closed using the sealing plate, making it easier for the staff to take out the chip.

[0015] Preferably, the upper end surface of the base is provided with an installation groove which is staggered with the sealing groove. The cross-section of the installation groove is rectangular and is vertically arranged. An adjusting rod is provided in the installation groove. The lower end of the adjusting rod is provided with a first inclined surface facing the sealing plate. The side wall of the sealing plate is provided with a second inclined surface, and the first inclined surface and the second inclined surface are abutted against each other.

[0016] When the chip needs to be taken out, the staff presses the fixing column downward, and through the cooperation between the first inclined surface and the second inclined surface, the sealing plate moves toward the side of the sealing hole, thereby closing the sealing hole.

[0017] Preferably, a spring is fixed on the side wall of the sealing groove far from the mounting groove. The spring is arranged horizontally, and the other end of the spring is fixed on the sealing plate. When the sealing plate blocks the exhaust hole, the spring is in a compressed state.

[0018] After taking out the chip, the staff no longer presses the fixing column, and uses the spring to move the sealing plate away from the exhaust hole, so that the exhaust hole is reconnected.

[0019] A fixing column with one end extending out of the mounting slot is fixed on the upper end surface of the adjusting rod, and a limiting portion for limiting the position of the adjusting rod is provided at the notch of the mounting slot.

[0020] A limiting portion is provided at the notch of the installation slot to limit the adjusting rod and prevent the adjusting rod from sliding out of the installation slot.

[0021] The upper end surface of the mounting seat is provided with a plurality of through slots.

[0022] When the sealing plate blocks the exhaust hole, the cavity is no longer connected to the exhaust mechanism, but the cavity itself still maintains a negative pressure state, and the micropores still have a certain adsorption effect on the chip. Therefore, multiple through-slots are opened on the upper end surface of the mounting base to allow external air to enter the cavity through the through-slots, thereby balancing the negative pressure within the cavity. The slots are shallow in depth and narrow in width, which limits the speed at which external air enters the cavity through the through-slots, ensuring that the exhaust pipe can maintain a continuous negative pressure state in the cavity when the chip is installed on the mounting base.

[0030] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0031] Example

[0032] like Figure 1-5 As shown, a chip fixing device for a chip scanner includes a base 110. A chip placement cavity 120 is defined on the upper end surface of the base 110. A mounting seat 130 is formed by an upward protrusion at the center of the bottom wall of the chip placement cavity 120. The mounting seat 130 is elongated, with the left and right sidewalls of the mounting seat 130 aligned with the left and right inner sidewalls of the chip placement cavity 120. The distance between the front and rear sidewalls of the mounting seat 130 is less than the distance between the front and rear sidewalls of the chip placement cavity 120, and the height of the mounting seat 130 is lower than the upper end surface of the base 110. A cavity 1301 is defined within the mounting seat 130, and micropores 1302 are uniformly distributed on the upper end surface of the mounting seat 130, communicating with the cavity 1301. The mounting seat 130 is also provided with an exhaust mechanism communicating with the cavity 1301.

[0033] A cavity 1301 is provided in the mounting base 130, and micropores 1302 connected to the cavity 1301 are evenly provided on the upper end surface of the mounting base 130. A plurality of through grooves 1303 are provided on the upper end surface of the mounting base 130. The through grooves 1303 are shallow in depth and small in width, thereby limiting the speed at which external air enters the cavity 1301 through the through grooves 1303, ensuring that when the chip is mounted on the mounting base 130, the exhaust pipe 160 can keep the cavity 1301 in a continuous negative pressure state.

[0034] The mounting base 130 is also provided with an exhaust mechanism connected to the cavity 1301. The exhaust mechanism includes an exhaust hole 1101. The lower end surface of the base 110 is provided with an exhaust hole 1101 connected to the cavity 1301. An exhaust pipe 160 is provided at the exhaust hole 1101. The exhaust pipe 160 extracts air from the cavity 1301 through the exhaust hole 1101, making the internal pressure of the cavity 1301 lower than the external pressure.

[0035] The base 110 is provided with a blocking groove 1102 staggered with the air extraction hole 1101. The blocking groove 1102 has a rectangular cross-section and is arranged horizontally. A blocking plate 1103 is provided in the blocking groove 1102 and can move horizontally in the blocking groove 1102. The blocking plate 1103 is used to control the opening and closing of the air extraction hole 1101. The upper end surface of the base 110 is provided with a mounting groove 1104 staggered with the blocking groove 1102. The mounting groove 1104 has a rectangular cross-section and is arranged vertically. An adjusting rod 140 is provided in the mounting groove 1104. The lower end of the adjusting rod 140 is provided with a first inclined surface 1401 facing the blocking plate 1103. The side wall of the blocking plate 1103 is provided with a second inclined surface 1106. The first inclined surface 1401 and the second inclined surface 1106 abut against each other. A limiting portion 1105 is provided at the notch of the installation slot 1104 to limit the adjustment rod 140 and prevent the adjustment rod 140 from sliding out of the installation slot 1104 .

[0036] A spring 150 is fixed on the side wall of the sealing groove 1102 on the side far from the mounting groove 1104. The spring 150 is arranged horizontally, and the other end of the spring 150 is fixed on the sealing plate 1103. When the sealing plate 1103 blocks the exhaust hole 1101, the spring 150 is in a compressed state.

[0037] The specific operation process of the chip fixing device in this embodiment is as follows: Before use, the exhaust mechanism (not shown in the figure) is turned on, so that the exhaust pipe 160 extracts the gas in the cavity 1301, causing the cavity 1301 to be in a negative pressure state, and the chip is placed on the mounting base 130, thereby achieving the installation and fixation of the chip; when the chip needs to be removed, the staff presses the fixing column 1402, thereby using the blocking plate 1103 to block the exhaust hole 1101, so that the cavity 1301 and the exhaust pipe 160 are no longer connected; the outside air can enter the cavity 1301 through the through groove 1303, thereby balancing the negative pressure in the cavity 1301. At this time, the micropore 1302 no longer attracts the chip, and the staff uses a tool to tilt the chip to one side, making it more convenient to remove the chip. After removing the chip, the staff no longer presses the fixing column 1402, and the blocking plate 1103 moves under the action of the spring 150, so that the cavity 1301 and the exhaust pipe 160 are connected again.

[0038] In short, the above is only a preferred embodiment of this embodiment, and all equivalent changes and modifications made according to the scope of the patent application of this embodiment should fall within the scope of coverage of the patent of this embodiment.
