Description

Technical Field

[0001] The present invention relates to a feeding device for transporting high-precision products, especially for the transportation and feeding of electronic components in the semiconductor testing and packaging industry. Background Art

[0002] Semiconductor devices (i.e., chips) need to undergo a series of test operations before taping. Currently, there is no integrated device on the market that can simultaneously complete the test and taping operations, resulting in very low production efficiency for semiconductor device test taping. In addition, due to the small size and light weight of semiconductor devices, it is not suitable to use a conveyor belt for transportation, so it is difficult to achieve stable and continuous feeding.

[0003] Currently, the conveying tracks of some high-precision products have single-row air blowing holes, and the air blowing is uneven, which will cause products or electronic components to jam in the track. There is no reverse blowing mechanism, and only manual removal of the products is possible. There is no outlet track to suck the products on the track, but instead, the products are pressed on the track, which is likely to cause damage to the products.

[0004] For example, Chinese Patent CN201920705376.0, a feeding air rail mechanism for a chip test sorter; CN201521135797.2, a feeding device based on an air track. Using a single air blowing port and without a reverse blowing design, not only is it easy to jam the material, but also after jamming, the products must be manually removed, affecting production efficiency and being very inconvenient.

[0010] Further, for the electronic component loading and conveying air rail according to the above design scheme, it is characterized in that a reverse blowing gas guiding block is provided on the outlet track; the reverse blowing gas guiding block includes a left reverse blowing gas guiding block and a right reverse blowing gas guiding block.

[0011] Further, for the electronic component loading and conveying air rail according to the above design scheme, it is characterized in that the sliding strip is arranged along the material conveying direction; at least two sliding strips are provided; the sliding strips are arranged parallel to each other.

[0012] Further, for the electronic component loading and conveying air rail according to the above design scheme, it is characterized in that the vibration device includes a mounting plate, an electromagnet, and an adjusting mounting bracket; the mounting plate is fixedly connected to the support bottom plate through a connecting piece; the adjusting mounting brackets are evenly distributed on the mounting plate; the electromagnet is arranged on the adjusting mounting bracket; the adjusting mounting bracket is used for adjusting the distance between the electromagnet and the upper cover plate of the track.

[0013] Further, for the electronic component loading and conveying air rail according to the above design scheme, it is characterized in that a mounting chute is provided on the mounting plate; the adjusting mounting bracket is arranged in the mounting chute; the adjusting mounting bracket can slide freely and be adjusted in the mounting chute and is fixed by a bolt; a rubber head is provided on the vibration head of the electromagnet; the rubber head is in close contact with the upper cover plate of the track.

[0015] The technical effects of the present invention are as follows: The present invention has developed a new type of conveying air rail for electronic components. The main body of the rail has double-row staggered air holes, which can blow air evenly to transport the products to the outlet rail. When the positive pressure gas used in ordinary factories is passed through the bottom plate, the reverse blowing gas guide block will blow the products back to the feeding mechanism to prevent product jamming.

When it is necessary to pause the feeding, the products can be fixed by suction; when it is necessary to resume the feeding, the products are blown out by blowing to resume the feeding.

[0017] At the same time, the conveying air rail of the prior art is prone to material jamming and stopping at the feeding end, and at this time, it can only be taken out manually, which is not conducive to production. For this reason, this application is provided with a reverse blowing gas guide block on the outlet rail. The reverse blowing gas guide block includes a left reverse blowing gas guide block and a right reverse blowing gas guide block, which can blow the products back to the feeding mechanism after material jamming.

[0018] In addition, this application also adds vibration-assisted feeding. By setting a vibration device on the upper cover plate of the rail, the entire rail is vibrated to assist in product conveying and prevent product jamming. BRIEF DESCRIPTION OF THE DRAWINGS
