Description

Technical Field

[0001] The utility model relates to the technical field of chip clamping tooling, in particular to a chip clamping device. Background Art

[0002] A chip refers to an integrated circuit, which is a way to miniaturize circuits and is often manufactured on the surface of a semiconductor wafer. Strictly speaking, the true meaning of a chip refers to a tiny semiconductor chip inside an integrated circuit package, that is, a die.

[0003] When the chips are tested in small batches, a simple workbench is generally used to fix the chips. For example, the existing patent with publication number CN219189888U discloses a chip testing clamping tool. The tool can clamp and fix chips of different widths for testing through a first clamp and a first spring. Through the cooperation of the first clamp and the second clamp, longer chips can be fixed and tested. In this way, chips of different specifications can be tested. The application range is wide, and the clamping friction is increased by an anti-slip plate to prevent the chip from slipping out of the clamp.

[0004] However, in the above technical solution, when the user uses the first clamp and the first spring to clamp the chip, it is difficult for the user to control the preload force of the spring. When the first clamp abuts against the chip, the preload force of the first spring is too large, so the chip may be damaged. Therefore, it is a common goal of technical personnel in this field to invent a chip clamping device that can clamp the chip nearly without damage. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative labor are within the scope of protection of the utility model.

[0026] Example: See Figures 1 to 5 The embodiment of the utility model provides a technical solution: a chip clamping device, including a workbench 1 and a core body 2, a first plate body 3 and a second plate body 4 are arranged on the workbench 1 at intervals along the height direction of the workbench 1, and also includes a clamping structure 5, the clamping structure 5 includes: an electric push rod 6, which is arranged on the first plate body 3, and its output end is arranged toward the second plate body 4; a first clamping plate 7, which is fixed on the output end of the electric push rod 6 and is suitable for placing the core body 2; a second clamping plate 8, which is arranged on the second plate body 4 and is arranged relative to the first clamping plate 7; and at least two pressure sensors 9, which are arranged on the first clamping plate 7 and the second clamping plate 8 relative to each other, and are connected to the electric push rod 6 and an external power supply through a controller 10.

[0027] When implementing the above scheme, the user first places the core 2 vertically upward on the first clamping plate 7, and then drives the electric push rod 6, and uses the electric push rod 6 to drive the first clamping plate 7 to move the core 2 toward the second clamping plate 8 until the core 2 abuts against the second clamping plate 8. At this time, the two ends of the core 2 will apply pressure to the pressure sensors 9 at both ends of the core 2 as the electric push rod 6 advances. When the two pressure sensors 9 sense that the pressure reaches the pressure preset by the user, the pressure sensor 9 will control the electric push rod 6 to stop advancing through the controller 10 to prevent the first clamping plate 7 and the second clamping plate 8 from clamping and damaging the chip.

[0028] In this embodiment, rubber discs 11 are provided on the first clamping plate 7 and the second clamping plate 8; when the first clamping plate 7 and the second clamping plate 8 clamp the core 2 through the electric push rod 6, the rubber discs 11 on the clamping plates will reduce the pressure on the core 2, further reducing the probability of the first clamping plate 7 and the second clamping plate 8 damaging the core 2.

[0029] In this embodiment, a notch 12 is further provided on the rubber disc 11, the length and width of the notch 12 match the length and width of the chip, and is suitable for the core 2 to be at least partially inserted into the notch 12; when the core 2 is placed on the first clamping plate 7, by placing the core 2 in the notch 12, the first clamping plate 7 and the second clamping plate 8 are more stable when clamping the core 2.

[0030] In this embodiment, a trapezoidal hole 13 is formed on the rubber disc 11, and the trapezoidal hole 13 is formed on the top of the slot 12, and the trapezoidal hole 13 is suitable for the core 2 to be at least partially inserted into the trapezoidal hole 13; when the core 2 is placed in the slot 12, the core 2 can be placed into the slot 12 more easily through the trapezoidal hole 13 on the first clamping plate 7.

[0031] In this embodiment, a motor 14 is provided on the second plate body 4, and the output end of the motor 14 is arranged toward the first clamping plate 7, and the second clamping plate 8 is arranged on the output end. A deep hook ball bearing 15 is installed on the first plate body 3, and the inner ring of the deep hook ball bearing 15 is coaxially fixed with the electric push rod 6, and the motor 14 is connected to an external power supply; when it is necessary to detect the two sides of the core body 2, the second clamping plate 8 is driven by the driving motor 14 to rotate, and the second clamping plate 8 drives the core body 2 to rotate. Since the inner ring of the deep hook ball bearing 15 is coaxially fixed with the electric push rod 6, when the chip rotates, it will drive the electric push rod 6 and the first clamping plate 7 to rotate together, so that the user can detect each side of the core body 2 by controlling the rotation angle of the motor 14.

[0032] In this embodiment, the first plate body 3 is driven by two cylinders 16 and can be moved along the height direction of the workbench 1; when it is necessary to detect core bodies 2 of different lengths, the first plate body 3 is moved along the height direction of the workbench 1 by the two cylinders 16, so that cores of different heights can be clamped.

[0033] Working principle: When the core 2 needs to be clamped, the user first places the core 2 vertically upward on the rubber disc 11 at the first clamping plate 7, inserts the core 2 into the slot 12 more easily through the trapezoidal hole 13, and then drives the electric push rod 6, and uses the electric push rod 6 to drive the first clamping plate 7 to move the core 2 toward the second clamping plate 8 until the core 2 abuts against the second clamping plate 8. At this time, the two ends of the core 2 will apply pressure to the pressure sensors 9 at both ends of the core 2 as the electric push rod 6 advances. When the two pressure sensors 9 sense that the pressure reaches the pressure preset by the user, the pressure sensor 9 will control the electric push rod 6 to stop advancing through the controller 10 , preventing the first clamping plate 7 and the second clamping plate 8 from clamping and damaging the chip; when it is necessary to inspect the two sides of the core 2, the second clamping plate 8 is driven to rotate by the driving motor 14, and the second clamping plate 8 then drives the core 2 to rotate. Since the inner ring of the deep hook ball bearing 15 is coaxially fixed with the electric push rod 6, when the chip rotates, it will drive the electric push rod 6 and the first clamping plate 7 to rotate together, so that the user can detect each side of the core 2 by controlling the rotation angle of the motor 14; when it is necessary to inspect cores 2 of different lengths, the first plate 3 is moved along the height direction of the workbench 1 by two cylinders 16, which has the function of clamping cores 2 of different heights.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
