[0025] As Figure 1-2 shown, a loading device for integrated circuit current testing in this embodiment includes a base 241, a bending channel 242 and a horizontal channel 243. The horizontal channel 243 is parallel to the left - right direction and is fixedly arranged on the base 241. The bending channel 242 is connected to the right end of the horizontal channel 243. A stop block 244 is arranged at the left end of the horizontal channel 243. A first blowing pipe 245 is arranged on the bending channel 242, and a second blowing pipe 246 is arranged on the horizontal channel 243. Two clamping units 247 are arranged on the base 241, and the two clamping units 247 are symmetrically arranged on the front and rear sides of the horizontal channel 243. During operation, the material pipe is arranged obliquely, so that the products in the material pipe slide obliquely downward under the action of gravity into the bending channel 242. Due to the light weight of the products, the products stop moving after sliding into the bending channel 242 by gravity. At this time, air is blown out through the first blowing pipe 245 and acts on the products in the bending channel 242, so that the products in the bending channel 242 are transported into the horizontal channel 243 under the action of the air flow. Then, the second blowing pipe 246 blows out air and acts on the products in the horizontal channel 243. Under the action of the air flow, the products in the horizontal channel 243 move to the right and abut against the stop block 244. Then, through the two clamping units 247, the products at the stop block 244 are clamped in the front - rear direction, that is, the top of the products is clamped, which is convenient for the nozzle 53 to suck the products at the stop block 244 and move them to the subsequent detection mechanism. Moreover, by the action of air on the products, the impurities on the products can be blown away, thereby improving the detection accuracy;

[0026] Among them, the stop block 244 is made of flexible material, which can play a buffering effect when the products abut against the stop block 244. At the same time, the air flow generated by the second blowing pipe 246 acts on the products, so that the products always abut against the stop block 244, realizing the positioning of the stop block 244 in the left - right direction;

[0027] The clamping unit 247 includes a clamping block 2471 and a clamping cylinder 2472. The cylinder body of the clamping cylinder 2472 is fixedly arranged on the base 241, and the clamping block 2471 is fixedly connected to the piston end of the clamping cylinder 2472. The clamping block 2471 is driven by the clamping cylinder 2472 to move in the front - rear direction. After the products abut against the stop block 244, the clamping cylinder 2472 is started, so that the two clamping blocks 2471 move closer to clamp the products, that is, the positioning of the products is realized, which is convenient for improving the accuracy of grasping the products;

[0028] The positioning component 24 further includes two sets of fixing units 249. The two sets of fixing units 249 respectively correspond to the bending channel 242 and the horizontal channel 243. Each set of fixing units 249 is provided with two, and the two fixing units 249 in the same group are symmetrically arranged front and back. The two sets of fixing units 249 are respectively used to fix the horizontal channel 243 and the bending channel 242.

[0029] The fixing unit 249 includes a connecting block 2491. A tightening screw 2492 is threadedly connected to the connecting block 2491. By using the two tightening screws 2492 to press against the horizontal channel 243 or the bending channel 242 front and back, the fixing of the horizontal channel 243 or the bending channel 242 is realized. Moreover, when it is necessary to adjust the position of the horizontal channel 243 or the bending channel 242, loosen the tightening screw 2492. After the position of the horizontal channel 243 or the bending channel 242 is adjusted, then tighten the tightening screw 2492.

[0030] An air hole 2431 is provided at the top of the horizontal channel 243. One end of the second blow pipe 246 is inserted into the air hole 2431, and the air discharged from the second blow pipe 246 is conveyed into the horizontal channel 243 through the air hole 2431.

[0031] The bending angle of the bending channel 242 is 120 degrees.

[0032] A sensor 248 is provided on the base 241 to detect whether the product abuts against the stopper 244.

[0033] In summary, by providing the first blow pipe 245 and the second blow pipe 246, not only the power required for the movement of the product is provided, but also the impurities on the product can be blown off, thereby improving the detection accuracy. Secondly, by clamping the product in the front and back directions at the stopper 244, the accuracy of grasping the product is improved, that is, it is convenient to improve the accuracy of conveying the product to the subsequent detection mechanism.

[0034] In addition to the above embodiments, the present invention also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present invention.
