[0002] In the tube loading and unloading mechanism of the chip testing and sorting machine, the track is often used to load and unload the chips. In the unloading mechanism, the compressed air is blown out by the front air blowing block to push the chip into the track, and the track outlet is aligned with the tube, and the chip enters the tube.
[0003] At present, in actual testing, the front-end blowing block will generate a vacuum at the outlet, sucking the chip back, and may cause unstable blowing. In addition, due to the manufacturing errors of the chip, the manufacturing errors of the track, the position changes of the front-end chip, etc., the chip cannot move at a fixed speed and trajectory, so it is necessary to ensure that the front-end blowing pressure is sufficient to ensure that all chips have enough power and each chip can enter the material tube.

Therefore, both the connecting rod position fine-tuning assembly and the tension spring fine-tuning assembly can indirectly adjust the downward pressure of the roller 108, thereby achieving the effect of decelerating the moving chip.
[0048] Actual Fig.10 As shown, in the default state of the chip deceleration device 100, the roller 108 is pulled down by the tension spring 109, and the roller 108 is in an overpressure state relative to the chip. The roller 108 is made of antistatic soft material, which can protect the roller 108 from damaging the chip itself when pressing down the chip.
[0049] Specifically, in this embodiment, the track assembly 200 includes a track cover 201, a bottom rail 202, a blowing block 203, a material receiving block 204, and a blowing assembly. The track cover 201 is installed on the bottom rail 202, and a blowing conveying track for the chip 1 is formed between the two. The blowing block 203 and the material receiving block 204 are both installed on the bottom rail 202. The chip 1 is placed on the material receiving block 204 by a feeding mechanism. The blowing block 203 is arranged on the right end face of the bottom rail 202. The blowing assembly includes a plurality of first air joints 205 and second air joints 206. The second air joint 206 is installed on the blowing block 203. The air pipe of the second air joint 206 The passage is connected with the vertical chamber inside the blowing block 203. A blowing hole 2 is provided at the connection between the blowing block 203 and the blowing conveying track. The outer diameter of the blowing hole 2 is tangent to the upper wall of the vertical chamber. A 1 mm air avoidance distance is provided at the front end of the blowing hole 2. The length of the blowing hole 2 is related to the diameter of the blowing hole 2. The first air joint 205 is evenly arranged on the track cover 201. Oblique air holes 3 of the same size are provided at the connection between the track cover 201 and the first air joint 205. The inclination direction of the oblique air holes 3 points to the direction of movement of the chip 1. The roller 108 of the chip deceleration device 100 falls into the deceleration groove provided on the track cover 201.
[0050] In the embodiment, each air joint is provided with an oblique air hole pointing to the movement direction of the chip, and compressed air is blown in to assist the movement of the chip. When the chip moves, the compressed air enters the vertical chamber inside the blowing block 203 from the second air joint 206. When the air passes through the reduced flow section from the large pipe diameter, the flow velocity increases, and the explosive gas blown out from the blowing hole 2 pushes the chip to move. The air hole length of the blowing hole 2 affects the size of the blowing force at the outlet end. The longer the length, the smaller the force of the compressed air blown out, so the length of the blowing hole 2 should be shortened as much as possible. In the embodiment, when the diameter of the blowing hole is 0.5mm, the length of the blowing hole 2 is 0.25mm.
[0051] The upper wall of the vertical chamber inside the blowing block 203 is tangent to the outer diameter of the blowing hole, which can avoid air turbulence. When blowing, a vacuum area will be formed at the outlet end of the blowing hole 2 in the blowing block 203, such as Figure 8 As shown in the middle wave position, a 1mm gap is designed at the front end of the blowing block to prevent the chip from being sucked back by the blowing block when the feeding position of the front feeding mechanism is offset, so that the chip can be blown into the track normally.
[0052] Specifically, in this embodiment, according to the movement direction of the chip, the first air connector 205 in the blowing assembly is connected to six air inlets from right to left in sequence, and the air inlets include the second air inlet 402, the third air inlet 403, the fourth air inlet 404, the fifth air inlet 405, the sixth air inlet 406, and the seventh air inlet 407. The first air inlet 401 supplies air to the blowing block 203, and the seventh air inlet 407 supplies air to the cylinder 105 and the leftmost first air connector 205 on the track cover 201 at the same time;
[0053] A timing unit is provided in the air supply control system, and a delayed air supply duration and a continuous air supply duration are provided for any air inlet. Based on the air supply of the first air inlet 401, air is supplied to the air inlets from right to left in sequence to the sixth air inlet 406;
[0054] For any two adjacent air inlets, when the previous air inlet starts to supply air, the timing unit counts the air supply duration of this air inlet, and when the timing unit reaches the delayed air supply duration, the next adjacent air inlet starts to supply air, and the air supply process of the subsequent air inlets is sequentially carried out to the sixth air inlet 406;
[0055] When the air supply duration for any air inlet reaches the continuous air supply duration, the air supply to this air inlet is terminated.
[0056] Specifically, in this embodiment, a first air supply duration for the seventh air inlet 407 is also provided in the air supply control system. When the timing unit starts timing the air supply duration of the first air inlet 401 and reaches the first air supply duration, the air supply control system supplies air to the seventh air inlet 407.
[0057] In the embodiment, since the air inlets are arranged according to the first air joint 205 evenly arranged on the track cover 201, the seven air inlets are, from right to left, the first air inlet 401, the second air inlet 402, the third air inlet 403, the fourth air inlet 404, the fifth air inlet 405, the sixth air inlet 406, and the seventh air inlet 407, and the distances between adjacent air inlets are equal.
[0058] During the actual air intake process, the chip moves between any two adjacent air inlets for 40ms. When the chip is blown by the first air inlet 401, it reaches the second air inlet 402 after 40ms, and controls the air intake of the second air inlet 402 to push the chip forward. After 40ms, it reaches the third air inlet 403, and the third air inlet 403 blows the chip, and so on to the sixth air inlet 406. The above process is set in the air supply control system, that is, the air supply time of the second air inlet 402 relative to the first air inlet 401 is delayed by 40ms, and the air supply time of the third air inlet 403 relative to the first air inlet 401 is delayed by 80ms, and so on to the sixth air inlet 406. It takes 240ms to go from the first air inlet 401 to the seventh air inlet 407. Since the seventh air inlet 407 is the first air connector 205 on the leftmost side of the track cover 201, the first air connector 205 here is located at the left side of the track cover 201 and is bent downward. The deceleration device decelerates the chip here. Therefore, the blowing delay of the seventh air inlet 407 relative to the first air inlet 401 needs to be greater than 240ms. In the embodiment, the first air supply duration is set to 300ms, the continuous air supply duration is 100ms, and the delayed air supply duration is 40ms.
[0059] The chip 1 is placed on the receiving block 204 by the feeding mechanism, blown into the track by the blowing block 203, and reaches the chip deceleration device 100 after 240ms. If the chip speed is fast, the tension spring force can be directly overcome to lift the roller 108. After passing the roller 108, the chip is decelerated and slides into the material tube 300 by gravity and the original remaining thrust. After 300ms, the air inlet 7 blows, the cylinder is pressed down, the roller is lifted, and at the same time, the oblique air hole of the seventh air inlet 407 blows air.
[0060] If the chip speed is too slow to overcome the tension spring force, the chip is blocked by the roller. After 300ms, the air inlet 7 supplies air, presses down the cylinder, lifts the roller, and at the same time, the oblique air holes of the seventh air inlet 407 blow air to blow the chip into the material tube 300. The air blowing assembly, the chip deceleration device and the air supply control system are combined to adjust the chip position during the air blowing and conveying process of the chip, ensuring the stability of the chip during the air blowing and conveying process, protecting the chip from damage caused by strong impact between chips, and reducing the machine alarm rate caused by chip jamming, thereby improving the efficiency of the test, improving the stability of the machine, reducing the defective rate, and improving the quality of the product.
[0061] Specifically, in this embodiment, when the diameter of the blowing hole 2 is 0.5 mm, the length of the blowing hole 2 is 0.25 mm.
[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
