Description

Technical Field

[0001] The utility model relates to the technical field of IC chip processing, in particular to an IC chip suction mechanism. Background Art

[0002] An IC chip (Integrated Circuit) is an integrated circuit formed by placing a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic substrate to make a chip. Almost all chips seen today can be called IC chips.

[0003] In the prior art, an IC chip suction mechanism is used to suck the chip and cooperate with the movement of the relevant manipulator to realize the movement of the chip. When a conventional suction mechanism sucks the IC chip, it is necessary to attach the suction mechanism to the IC chip. However, there is an unstable bonding force between the suction mechanism and the IC chip. There is a problem that the bonding is not tight and cannot be sucked, or the bonding force is too large, causing damage to the IC chip. At the same time, the traditional suction mechanism has only one suction cavity. When there is a gap between the suction cavity and the IC chip, the IC chip cannot be sucked and the suction is unstable. Utility Model Content

[0004] The utility model provides an IC chip suction mechanism to solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an IC chip suction mechanism, comprising a top plate, the four corners of the lower surface of the top plate are rectangular and fixedly installed with a buffer mechanism, a cross plate is fixedly installed between the lower surfaces of the buffer mechanism, an adsorption head is fixedly installed on the lower surface of the cross plate, four adsorption cavities are opened between the surrounding sides of the adsorption head and the lower surface, and connecting mechanisms are fixedly installed on the surrounding sides of the adsorption head corresponding to the adsorption cavity, and the upper side ends of the connecting mechanisms are connected to the air pipe joints, and the air pipe joints are fixedly installed on the lower side wall of the top plate.

[0008] Furthermore, a rubber pad is fixedly mounted on the lower surface of the adsorption head, and adsorption holes are provided on the rubber pad at positions corresponding to the four adsorption cavities.

[0009] Furthermore, the connecting mechanism includes a first hose, a solenoid valve and a second hose. The first hose is fixedly installed on the side of the adsorption head corresponding to the adsorption chamber. The upper end of the first hose is connected to the solenoid valve. The solenoid valve is installed on the upper surface of the horizontal plate. The upper port of the solenoid valve is connected to the air pipe joint through the second hose.

[0010] Furthermore, a through hole for the first hose to pass through is provided on the transverse plate at a position corresponding to the first hose.

[0011] Compared with the prior art, the utility model provides an IC chip suction mechanism, which has the following beneficial effects:

[0012] 1. The IC chip suction mechanism monitors the upward force of the horizontal plate by setting a buffer mechanism, that is, the upward force of the suction head on the lower surface of the horizontal plate is monitored, so that the bonding force between the suction mechanism and the IC chip can be monitored to make the bonding force between the two moderate, avoiding the problem that the bonding suction head and the IC chip are not tightly bonded and cannot be sucked, or the bonding force is too large to damage the IC chip, thereby ensuring the stability of suction.

[0020] Specifically, a mounting frame 8 is fixedly mounted on the upper surface of the top plate 1 , and a mounting hole 9 is formed on the upper side wall of the mounting frame 8 .

[0021] In this embodiment, the mounting holes 9 on the mounting frame 8 are conveniently connected to the manipulator via screws, so that the manipulator drives the suction mechanism to move.

[0022] Specifically, the buffer mechanism 2 includes a spring 201, a pressure sensor 202, a guide rod 203 and a guide hole 204. The spring 201 is fixedly installed on the lower surface of the top plate 1, the pressure sensor 202 is fixedly installed on the lower surface of the spring 201, the guide rod 203 is fixedly installed on the upper surface of the pressure sensor 202, and a guide hole 204 is opened on the top plate 1 corresponding to the guide rod 203, and the guide rod 203 is movably inserted in the guide hole 204.

[0023] In this embodiment, the spring 201 pushes the pressure sensor 202 to move downward, so that the pressure sensor 202 monitors the upward force of the horizontal plate 3, that is, monitors the upward force of the adsorption head 4 on the lower surface of the horizontal plate 3. The guide rod 203 moves up and down in the guide hole 204 with the pressure sensor 202, so that the up and down movement process of the pressure sensor 202 is stable, that is, the up and down movement process of the adsorption head 4 on the lower surface of the horizontal plate 3 is stable.

[0027] In this embodiment, the solenoid valve 602 is opened, and the air pipe connector 7 can evacuate the air in the adsorption chamber 5 through the first hose 601 and the second hose 603 .

Then, the IC chip applies an upward force to the suction head 4 on the upper surface of the rubber pad 10, so that the pressure sensor 202 monitors the upward force of the suction head 4 on the lower surface of the cross plate 3. When the forces of the two reach the set value, the information is fed back to the controller, and the controller stops the manipulator from moving downward, so that the suction The fitting strength between the mechanism and the IC chip is monitored to ensure that the fitting strength between the two is moderate, to avoid the problem that the fitting adsorption head 4 and the IC chip are not tightly fitted and cannot be adsorbed, or the fitting strength is too large to damage the IC chip, to ensure the stability of absorption, the air pipe joint 7 is connected to the vacuum assembly, the solenoid valve 602 in the connecting mechanism 6 is opened, and the four adsorption chambers 5 are evacuated through the air pipe joint 7 and the first hose 601 and the second hose 603 in the four connecting mechanisms 6, so that the IC chip is adsorbed on the adsorption hole 11, and the four adsorption chambers 5 are connected to the air pipe joint 7 through a separate connecting mechanism 6, so that the adsorption head 4 has four adsorption chambers 5, when there is an adsorption chamber 5 that can adsorb the IC chip, the IC chip can be adsorbed, so that the IC chip absorption is more stable and efficient.

[0031] In summary, the IC chip suction mechanism can monitor the fitting strength between the suction mechanism and the IC chip through the buffer mechanism 2, so that the fitting strength between the two is moderate, avoiding the problems of loose fitting and excessive fitting strength that damages the IC chip. At the same time, it has four adsorption chambers 5. When there is an adsorption chamber 5 that can adsorb the IC chip, the IC chip can be sucked, making the IC chip suction more stable and efficient.
