[0002] An integrated circuit chip is an electronic component consisting of a silicon substrate, at least one circuit, a fixed sealing ring, a grounding ring, and at least one guard ring. The basic manufacturing process for integrated circuit chips often requires the use of a printing device. However, most existing printing devices cannot effectively secure the chip. The chip is easily displaced during printing, resulting in inaccurate printing positions and poor printing results. Furthermore, the printing process for different chip sizes requires the use of different equipment, resulting in relatively low printing efficiency for integrated circuit chips.

DETAILED DESCRIPTION

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Example 1: A printing device for processing integrated circuit chips, such as Figure 1 and Figure 2 As shown, it includes a base frame, a placement plate, a fixing frame, a clamping component, a printing component and a positioning component. A placement plate is welded to the upper part of the base frame, and the upper part of the base frame is connected to the fixing frame by rivets. The clamping component is arranged on the fixing frame, the silk-screen component is arranged on the base frame, and the positioning component is arranged on the base frame, and the positioning component is connected to the silk-screen component.

[0014] Furthermore, the clamping component includes a motor, a screw, a guide rod, a slider, a fixed plate, a splint, an electric push rod and a push block. The motor is welded on the fixed frame, and the fixed frame is rotatably connected to the screw rod. The screw rod is provided with two threads, and the two threads of the screw rod rotate in opposite directions. The screw rod is fixedly connected to the output shaft of the motor. The fixed frame is connected to the guide rod by bolts. Two sliders are slidably connected to the fixed frame. The two sliders are symmetrically arranged. Both sliders are connected to the screw rod by threads. Both sliders pass through the guide rod. Both sliders are welded with fixed plates. The lower parts of the two fixed plates are connected to splints by bolts, and both splints are in contact with the placement plate.

[0015] Furthermore, the printing components include a bracket, a long rod, a long plate, a second motor, a threaded rod, a limiting rod, a moving block, a moving frame, an electric push rod 2 and a laser print head. Two brackets are welded on the upper part of the base frame. The two brackets are connected by a long rod through bolts. The upper part of the base frame is connected to a long plate through rivets. The long plate is fixedly connected to the placement plate. The second motor is welded on the long plate. The long plate is rotatably connected to the threaded rod, which is fixedly connected to the output shaft of the second motor. A limiting rod is provided on the long plate. The moving block is slidably connected to the long plate. The moving block is threadedly connected to the threaded rod. The moving block passes through the limiting rod. A moving frame is provided on the moving block. The moving frame is slidably connected to the long rod. The electric push rod 2 is welded on the moving frame. The telescopic rod of the second electric push rod passes through the moving frame. A laser print head is provided on the telescopic rod of the second electric push rod.

[0016] Furthermore, the positioning component includes a scale plate and a triangular pointer block. The scale plate is connected to the base frame by rivets, and the scale plate is provided with scales. The triangular pointer block is welded on the moving block, and the triangular pointer block is in contact with the scale plate.

[0017] First, manually place the chip on the placement plate, and then manually start motor 1, motor 2, electric push rod 1 and electric push rod 2. The output shaft of motor 1 drives the screw to rotate, and the rotation of the screw drives the two sliders to move toward each other, and the two sliders drive the two fixed plates and the two splints to move toward each other, and the two splints will clamp the chip. Then the telescopic rod of electric push rod 1 will extend, and the telescopic rod of electric push rod 1 will drive the push block to move, and the push block will contact the chip, and the push block will drive the chip to move, and the chip will contact the long plate. Then the output shaft of motor 2 will drive the threaded rod to rotate, and the rotation of the threaded rod will drive the moving block and the triangular pointer block to move, and the moving block drives the moving frame, electric push rod 2 and laser print head to move. When the triangular pointer block moves to the appropriate scale, motor 2 will stop rotating, the telescopic rod of electric push rod 2 will extend, and the telescopic rod of electric push rod 2 will drive the laser print head to move downward, and the laser print head will print at the appropriate position on the chip. Then the telescopic rod of electric push rod 2 will retract, and the telescopic rod of electric push rod 2 will When the laser print head moves upward, the output shaft of motor 2 starts to rotate in the opposite direction, and the output shaft of motor 2 drives the threaded rod to rotate in the opposite direction. The reverse rotation of the threaded rod will drive the moving block and the triangular pointer block to move in the opposite direction, and the moving block drives the moving frame, electric push rod 2 and laser print head to move in the opposite direction. Then the telescopic rod of electric push rod 1 will shrink, and the telescopic rod of electric push rod 1 drives the push block to move in the opposite direction, and the push block is separated from the chip. The output shaft of motor 1 drives the screw rod to rotate in the opposite direction, and the screw rod rotation drives the two sliders to move away from each other. The two sliders drive the two fixed plates and the two clamping plates to move away from each other, and the two clamping plates no longer clamp the chip. Then the chip is manually removed and replaced on the placement plate. This reciprocating process can clamp the chip, making the chip more accurate when printing. At the same time, through the movement of the triangular pointer block on the scale plate, the laser print head can be moved to the printing position more accurately, thereby making the printing effect of the chip better, and can also adapt to chips of different sizes, making the printing efficiency of the chip higher.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
