Grading mechanism of surface mounted type electronic component testing and sorting machine

Abstract

The invention provides a grading mechanism of a surface mounted type electronic component testing and sorting machine, which is used in a fully-automatic surface mounted type electronic component testing and sorting machine in the field of semiconductor manufacture. The grading mechanism comprises a first synchronous belt conveying device, a second synchronous belt conveying device which is in mutual transmission connection with the first synchronous belt conveying device, a separating device which is in transmission connection with the first synchronous belt conveying device or the second synchronous belt conveying device, and a collecting device arranged below the separating device and used for receiving electronic components, wherein the motion region of the separating device is an inner wall of the separating device. The invention has the advantages of low cost, simple structure, multiple grading number, high speed and stable operation, and improves the quality and the efficiency of producing products by a machine.

Description

technical field [0001] The invention relates to the field of semiconductor manufacturing, and more specifically relates to a sorting mechanism for a fully automatic surface-mounted electronic component testing and sorting machine. Background technique [0002] The fully automatic surface mount electronic component testing and sorting machine is one of the key equipments of the surface mount electronic component production line. An automatic production equipment that classifies the test results of parameters or electrical parameters. It is mainly composed of six major mechanisms, including vibrating feeding mechanism, single picking mechanism, turntable or linear track transmission mechanism, product centering mechanism, grading mechanism and sorting receiving mechanism. The grading mechanism is one of the main mechanisms of the test sorting machine. The main function is to send the components to the receiving pipes of each receiving mechanism according to the classification...

Problems solved by technology

[0005] The second is to place two motors of the X and Y axes on the reference platform; one of the motors drives the platform to move back and forth, and the other motor is connected to a spline shaft to drag the upper platform to move left and right. The movement principle is as follows figure 1 As shown, the characteristic of this spline shaft is that it can both translate and rotate, so there is no need to place a motor on the middle platform, but it still needs to install a guide device, so the load is relatively small and the moving inertia is smaller than that of the first type. At the same time, the structure is simpler, and the assembly is also very easy, but the spline shaft used in this method is expensive, and it is also easy to wear, causing machine vibration and unstable operation, thus affecting the quality of the product.
