Description

[0001] The invention relates to the field of semiconductors, and in particular to an automatic tinning device for chip pins. Background Art

[0002] The main purpose of tinning the chip pins is to cover the pin surface with a layer of tin to increase its soldering contact performance and corrosion resistance. Through tinning, it can ensure a reliable connection between the pins and the circuit board or other components, and improve the stability and reliability of the overall circuit.

[0003] Most of the existing methods for tinning chip pins use immersion tinning, which mainly involves using liquid solder (solder) to wet the surface of the metal to be soldered to form a bonding layer that is different from both the metal to be soldered and the solder.

[0039] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0040] The present invention provides a chip pin automatic tinning device, such as Figure 1 , 2 , 4, 5, including:

[0041] The base 1 has a top surface on which a flux placement tank 2, a cleaning tank 3 and a tinning tank 4 are arranged in sequence from front to back;

[0042] The electric control box 5 is designed as a sealed structure, and two cooling fans 53 are arranged on the top of the electric control box 5. The electric control box 5 also includes an MES system 51 and a PLC system 52. The MES system 51 controls the production process and connects with the PLC system 52 to achieve real-time control and data collection of the production process, thereby improving production efficiency and product quality.

[0043] Two brackets 6 are fixedly mounted on the electric control box 5, and a Y-axis linear motion module 7 and a Z-axis linear motion module 8 are disposed on the top of the two brackets 6, and a touch screen 10 is also disposed at the front end of the Y-axis linear motion module 7;

[0044] The clamping jaw 9 is hinged at the bottom of the Z-axis linear motion module 8;

[0045] The guide plate 13 is arranged between the cleaning tank 3 and the tinning tank 4 to receive the dripping tin water and tin slag. The bottom of both ends of the guide plate 13 are provided with a collection box 14;

[0046] The bottom of the Z-axis linear motion module 8 is located just above the clamping jaw 9 and is detachably equipped with an air knife 19. Both ends of the top of the air knife 19 are connected to an elastic telescopic hose 20. The other end of the elastic telescopic hose 20 is connected to the electric control box 5. In the operating state, the airflow generated by the cooling fan 53 on the top of the electric control box 5 is transported to the air knife 19 through the elastic telescopic hose 20 to blow off the excess tin water and tin slag on the clamping jaw 9 and the chip.

[0047] The heat dissipation airflow generated by the heat dissipation fan 53 of the electric control box 5 is collected and discharged by using the elastic telescopic hose 20 and the wind knife 19, and then the tin water and tin slag remaining on the surface of the tin-plated chip and the clamp 9 are blown off, and at the same time, the guide plate 13 is used to receive them to avoid unnecessary pollution caused by dripping on the tin-plating equipment, and blowing off the excess residual tin water and tin slag is beneficial to the cleaning effect of the cleaning tank 3.

[0048] The back of the Z-axis linear motion module 8 is connected to the electric control box 5 with a blower mechanism 22, the active end of the blower mechanism 22 is connected to the Z-axis linear motion module 8, and the other end is connected to the electric control box 5. When the Y-axis linear motion module 7 drives the Z-axis linear motion module 8 to move horizontally, the active end of the blower mechanism 22 follows the Z-axis linear motion module 8 to move forward to realize airflow compression and transmit it to the electric control box 5 for increasing the airflow speed of the wind knife 19 in a short time. Among them, a "human" shaped filter 131 is provided on the guide plate 13, and the filter 1 The two ends of 31 point to the collecting box 14 respectively, a drain port 132 is provided in the middle of the rear end of the guide plate 13, and wind wheels 133 are also provided at both ends of the guide plate 13. A knocking rod 134 is hinged in the middle of the blades of the wind wheel 133, wherein one end of the knocking rod 134 connected to the blade is a rod-shaped structure, and the other end is a spherical structure for knocking the filter 131. The high-speed airflow blows the wind wheel 133 to rotate, so that the knocking rod 134 knocks the filter 131, thereby causing the filter 131 to vibrate and shake the tin slag on its surface into the collecting box 14.

[0049] A blowing mechanism 22 is additionally provided between the Z-axis linear motion module 8 and the electric control box 5. When the Z-axis linear motion module 8 moves forward to drive the clamping claw 9 and the chip to be transported to the cleaning tank 3, the movable end of the blowing mechanism 22 follows the movement of the Z-axis linear motion module 8 to squeeze the internal gas thereof and transport it toward the inside of the electric control box 5, thereby increasing the amount of gas inside the electric control box 5, and then increasing the air volume and air speed of the wind knife 19. The high-speed airflow drives the wind wheel 133 to rotate, so that the knocking rod 134 runs to knock the filter 131, causing the filter 131 to vibrate. The vibrating filter 131 cooperates with the high-speed airflow to discharge the tin slag accumulated on the surface of the filter 131 into the collection box 14. It is only necessary to clean the collection box 14 regularly, and to clean and maintain the tin plating equipment in the later stage. At the same time, the wind knife 19 after increasing the air volume and air speed blows and dries the cleaned chips, which is convenient for subsequent detection work.

[0050] The blowing mechanism 22 includes an air cylinder 221 connected to the electric control box 5 and an air rod 223 connected to the Z-axis linear motion module 8, wherein the air cylinder 221 is internally slidably connected to a piston 222, one end of the air cylinder 221 is detachably equipped with a cylinder cover 224, one end of the air rod 223 passes through the cylinder cover 224 and is connected to the piston 222, and a gas one-way valve 225 is provided on both the cylinder cover 224 and the piston 222, and the air inlet of the gas one-way valve 225 points to the electric control box 5.

[0051] When the Z-axis linear motion module 8 moves forward, the gas rod 223 is pulled, and the piston 222 squeezes the gas at the front end of the gas cylinder 221, and the gas is transported to the inside of the electric control box 5 under the action of the gas one-way valve 225, thereby increasing the air volume and air speed of the wind knife 19. When the Z-axis linear motion module 8 moves backward and resets, the outside world enters the front end of the gas cylinder 221 under the action of the gas one-way valve 225, and the piston 222 squeezes the gas at the rear end of the gas cylinder 221 again, so that the gas is transported to the inside of the electric control box 5 again, thereby increasing the air volume and air speed of the wind knife 19 again, and the cleaned chips are blown dry to facilitate subsequent detection work.

When tinning, the protective cover 17 is pulled down to completely cover the front end part of the equipment to prevent the staff from accidentally touching the moving module or the tin water and causing unnecessary dangerous accidents.

[0058] In this embodiment, if Fig. 9 As shown, the Y-axis linear motion module 7 includes a first motor 71, a first pulley 72, a first belt 73, a first guide rail 74 and a first slide 75, wherein the first motor 71 drives the first pulley 72 and the first belt 73 to operate, the first slide 75 is slidably installed on the first guide rail 74 and one end of which is fixedly connected to the first belt 73, so that the operating first belt 73 drives the first slide 75 to move horizontally, and the Z-axis linear motion module 8 is fixedly installed on the first slide 75 to realize that the Y-axis linear motion module 7 drives the Z-axis linear motion module 8 to move horizontally.

[0061] The working principle of the present invention is as follows: the clamping jaw 9 clamps the chip and immerses the chip into the tinning tank 4 for tinning through the Y-axis linear motion module 7 and the Z-axis linear motion module 8. After the tinning structure is formed, the chip is transported to the cleaning tank 3 for cleaning. During the transportation process, the heat dissipation airflow generated by the cooling fan 53 of the electric control box 5 is collected and discharged by using the elastic telescopic hose 20 and the wind knife 19, and then the tin-plated chip and the tin water and tin slag remaining on the surface of the clamping jaw 9 are blown off.

At the same time, when the Z-axis linear motion module 8 moves forward, the cooling airflow generated by the cooling fan 53 of the electric control box 5 is collected and discharged. When the clamping jaws 9 and the chip are moved to the cleaning tank 3, the movable end of the blowing mechanism 22 follows the movement of the Z-axis linear motion module 8 to squeeze the internal gas and transport it to the inside of the electric control box 5, thereby increasing the amount of gas inside the electric control box 5, and then increasing the air volume and air speed of the wind knife 19, and blowing the tin water and tin slag accumulated on the guide plate 13 into the collection box 14 for collection. When the chip enters the cleaning tank 3, the ultrasonic generator 31 is turned on for cleaning. After cleaning, the cleaned chip is still dried by the wind knife 19 with increased air volume and air speed, and finally the visual inspection equipment 12 is used for appearance inspection.
