Description

Technical Field

[0001] The utility model belongs to the technical field of chip detection, and particularly relates to a chip detection device convenient for positioning. Background Technique

[0002] A chip, also known as a microcircuit, a microchip, and an integrated circuit, refers to a silicon wafer containing an integrated circuit. It is very small in size and is often part of a computer or other electronic device. A chip is a general term for semiconductor component products and is the carrier of an integrated circuit. After the chip is produced, in order to ensure the normal use of the chip, the chip is usually detected, and at this time, a chip detection device is used.

[0003] For example, in the Chinese patent document with the publication number CN214409209U and the patent name of a positioning device for chip detection, it is mentioned that "it includes a workbench, a support frame, and a horizontal support rod. A placement groove is opened inside the workbench, and the placement groove is rectangular. The upper end of the workbench is fixedly connected to an internal thread seat by welding. The internal thread seats are distributed around the workbench. A lead screw is connected inside the internal thread seat. The outside of the lead screw is connected to a rotating handle by welding. The inside of the lead screw is connected to a fixing plate by welding. The outside of the fixing plate is connected to a protective cotton by bonding". This structure adjusts the position of the fixing plate through the rotating handle to firmly fix the chip at the central position and avoid instability or shaking during detection.

[0025] In the embodiments of the present utility model, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0026] In one embodiment of the present utility model, as Figures 1 to 3 shown, there is provided a chip detection device facilitating positioning, including a workbench 10, a placement table 11, a fixing mechanism, and a pressing mechanism 60. A fixing plate 101 is provided at the top of the workbench 10, and a detection mechanism 102, which is a detector, is slidably connected to the fixing plate 101. The placement table 11 is disposed in the center of the workbench 10 for placing the chip. The fixing mechanism includes a first fixing member 20 and a second fixing member. The first fixing member 20 is disposed outside the placement table 11, and a first pressure sensor 201 is provided inside the first fixing member 20. A first sliding member 50 is provided between the first fixing member 20 and the placement table 11, and the first sliding member 50 is electrically connected to the first pressure sensor 201. The first fixing member 20 is slidably connected to the first sliding member 50. The second fixing member is fixedly disposed inside the placement table 11. The first fixing member 20 and the second fixing member are used to fix both sides of the chip. Two groups of pressing mechanisms 60 are respectively disposed at the tops of the first fixing member 20 and the second fixing member for pressing the chip onto the placement table 11. A top rod 113 extending outward is provided on one side of the placement table 11 close to the second fixing member. A buffer member 40 for buffering the clamping force is provided inside the second fixing member. The top rod 113 abuts against the buffer member 40.

[0027] By setting the first pressure sensor 201 and the buffer component 40, when the chip is positioned and clamped, the first fixed component 20 moves toward the placement table 11 under the action of the first sliding component 50, clamps the chip between the first fixed component 20 and the second fixed component, and monitors the clamping force on the first fixed component 20 through the first pressure sensor 201. If the clamping force is too large, the first pressure sensor 201 sends a feedback signal, and the first sliding component 50 stops moving to avoid the middle of the chip from tilting upward or indentations on both sides due to excessive clamping force. At the same time, when clamping, the push rod 113 first contacts the buffer component 40 to buffer the impact force when the first fixed component 20 is clamped, reduce the impact force on the side of the chip, avoid the chip tilting in the middle due to excessive impact force, and improve the production quality of the chip.

[0028] Furthermore, the first fixing component 20 includes a first fixing seat 21. The first fixing seat 21 is arranged on the workbench 10 and is located on one side of the placement platform 11. The first fixing seat 21 is provided with a first vertical plate 22 protruding upward. The clamping mechanism 60 is located at the top of the first vertical plate 22, and the first pressure sensor 201 is located in the first vertical plate 22. When the chip is clamped, the first fixing component 20 is moved toward the placement platform 11 under the action of the first sliding component 50, and moves until the first vertical plate 22 is completely in contact with the side wall of the chip, then the chip is clamped between the first fixing component 20 and the second fixing component, and the clamping force on the first vertical plate 22 is monitored by the first pressure sensor 201. If the clamping force is too large, the first pressure sensor 201 sends a feedback signal, and the first sliding component 50 stops moving to avoid the middle of the chip from warping up or indentations on both sides due to excessive clamping force.

[0029] Furthermore, a sliding cavity opening outward is provided on one side of the first fixing seat 21. The buffer component 40 is provided in the sliding cavity. The ejector rod 113 can enter or leave the sliding cavity. When clamping, the ejector rod 113 enters the sliding cavity and contacts the buffer component 40, so as to buffer the impact force when the first fixing component 20 is clamped, reduce the impact force on the side of the chip, avoid the chip from warping in the middle due to excessive impact force, and improve the production quality of the chip.

[0030] Furthermore, the buffer component 40 includes a telescopic rod 41 and a first spring 42. One end of the telescopic rod 41 is fixedly connected to the sliding cavity, and the other end is connected to the limiting portion 43. The first spring 42 is sleeved on the telescopic rod 41 and is located between the limiting portion 43 and the sliding cavity. When clamping, the ejector rod 113 enters the sliding cavity and conflicts with the limiting portion 43 of the buffer component 40. Under the action of the first spring 42, the impact force of the first fixed component 20 when clamping is buffered, reducing the impact force on the side of the chip, preventing the chip from warping in the middle due to excessive impact force, and improving the production quality of the chip.

[0031] Furthermore, the first vertical plate 22 and the first fixing base 21 form an "L"-shaped block. First protective layers 23 are provided on both the first fixing base 21 and the first vertical plate 22. By providing the first protective layers 23, the surface of the chip is protected to avoid damage to the chip surface during positioning and clamping, thereby improving the production quality of the chip.

[0032] Furthermore, the first sliding member 50 includes a first sliding driving member 51 and a first transmission shaft 52. The first sliding driving member 51 is a motor, and the first sliding driving member 51 is provided on one side of the bottom end of the workbench 10. The first transmission shaft 52 is provided in the workbench 10 and is connected to the output end of the first sliding driving member 51. The first transmission shaft 52 is connected to the first fixing base 21 through a first slider. During clamping, the first sliding driving member 51 is started, the first sliding driving member 51 drives the first transmission shaft 52 to rotate, the first transmission shaft 52 drives the first fixing member 20 to approach the placement table 11, and after the chip is clamped according to the clamping force monitoring feedback of the first pressure sensor 201, the first driving member stops operating, thereby realizing automatic clamping of the chip and improving the clamping efficiency of the chip.

[0033] Further, the second fixing member includes a second fixing base 31. The second fixing base 31 is provided on the workbench 10 and is located inside the placement table 11. The second fixing base 31 is provided with an upwardly protruding second vertical plate 32. Second protective layers 23 are provided on both the second fixing base 31 and the second vertical plate 32. The pressing mechanism 60 is located at the top end of the second vertical plate 32. During clamping, one end of the chip is placed on the second fixing base 31 and abuts against the side wall of the second vertical plate 32. Under the action of the first sliding member 50, the first vertical plate 22 of the first fixing member 20 and the second vertical plate 32 press both ends of the chip, thereby realizing positioning and clamping of both sides of the chip.

[0034] Further, the pressing mechanism 60 includes a pressing driving member 61, a pressing plate 62, and two groups of pressing rods 63. The pressure driving member is a motor, and the pressing driving member 61 is provided at the center of the top ends of the first fixing member 20 and the second fixing member. The pressing plates 62 are provided inside the first fixing member 20 and the second fixing member and are connected to the output ends of the pressing driving member 61. The two groups of pressing rods 63 are symmetrically distributed at both ends of the pressing plate 62. A second spring 64 is provided between the pressing rod 63 and the pressing plate 62. After the chip is clamped by the first fixing member 20 and the second fixing member, the pressing driving member 61 is started, the pressing driving member 61 drives the pressing plate 62 to move downward, the pressing plate 62 drives the pressing rods 63 at both ends thereof to move downward, and the top surface of the chip is pressed. At the same time, the impact force generated during pressing by the second spring 64 is also reduced, the damage to the chip during pressing is reduced, and the production quality of the chip is improved.

[0035] Further, a second sliding member 70 is provided between the detection mechanism 102 and the fixing plate 101. The second sliding member 70 includes a second sliding driving member 71 and a second transmission shaft 72. The second sliding driving member 71 is disposed on one side of the top end of the workbench 10. The second transmission shaft 72 is disposed in the workbench 10 and is connected to the output end of the second sliding driving member 71. The second transmission shaft 72 is connected to the detection mechanism 102 through a second slider. Before detection, the second sliding driving member 71 is started. The second sliding driving member 71 drives the second transmission shaft to rotate. The second transmission shaft 72 drives the detection mechanism 102 to move left or right to adjust the position of the detection mechanism 102 to adapt to the detection scenarios of different types of chips and improve the versatility of the detection device.

[0036] Further, a second pressure sensor 111 is provided at the center of the placement table 11. A third protective layer 112 is provided on the surface of the placement table 11. By providing the second pressure sensor 111, it is convenient for the staff to timely know whether a chip is placed on the placement table 11 without going to the detection device to observe. At the same time, through the third protective layer 112, the chip is protected to avoid damage to the surface of the chip during detection.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
