Electronic component pick-up unit and working equipment for its application

Abstract

The invention discloses an electronic element pickup unit. The electronic element pickup unit comprises a body, at least one taking and placing piece and a drawing structure, wherein the body is provided with at least one bearing and sliding part; the at least taking and placing piece is mounted on the bearing and sliding part of the body; a suction nozzle is arranged on the bottom surface of the taking and placing piece; a vent which is communicated with the suction nozzle is formed in the outer peripheral surface of the taking and placing piece; according to the drawing structure, at least one drawing device is arranged between the body and the taking and placing piece, and the at least one drawing device is communicated with the vent of the taking and placing piece and an air extractor, so that the drawing device can directly suck the air at the suction nozzle of the taking and placing piece, the suction nozzle of the taking and placing piece is enabled to have suction to suck up and move an electronic element, and the taking and placing piece can be rapidly moved and reset when the reactive force pushing of the electronic element does not exist. The element configuration of the pickup unit can be reduced, the taking and placing piece is enabled to absorb the electronic element to move and realize the positive resetting, and the practical benefits that the cost is reduced and the application efficiency is promoted are realized.

Description

technical field [0001] The invention relates to an electronic component pick-up unit that can reduce the component configuration of the pick-up unit, and ensure that pick-and-place parts absorb the displacement of electronic components and operate and reset, thereby saving costs and improving use efficiency. Background technique [0002] Nowadays, pick-up units with pick-and-place parts are used in different operating equipment for pick-and-place and transfer of electronic components, please refer to figure 1 , is the pick-up unit 10 of the existing material transfer mechanism applied to the operation equipment. The pick-up unit 10 is provided with a body 11 assembled on the connecting piece 20 of the material transfer mechanism (not shown in the figure), and can be used as the first, second, and Displacement in three directions (such as X, Y, Z directions), the interior of the body 11 is provided with a step-shaped accommodation hole 111, and an air suction port 112 connect...

Problems solved by technology

[0003] However, this pick-up unit 10 is provided with a spring 14 sleeved on the pick-and-place piece 13 in order to make the pick-and-place piece 13 quickly reset in the third direction when pushed by the reaction force of no electronic components. In the main body 11, a step-like accommodation hole 111 is processed and manufactured. Not only is the accommodation hole 111 difficult to manufacture and the precision is low, but also a retaining edge 133 must be processed on the outside of the pick-and-place part 13 to accommodate the spring 14, thereby increasing the number of components. Cost and production are inconvenient; and because the air extraction pipe 12 is connected to the air intake 112 of the body 11, in order to prevent the air vent 132 of the pick-and-place part 13 from leaking, it is necessary to add a second defense at the top and bottom of the air vent 132 of the pick-and-place part 13. The O-rings 151, 152 used for leaking are more costly for components and time-consuming and inconvenient to assemble; in addition, when the outer ring surfaces of the two O-rings 151, 152 are closely attached to the inner wall of the housing hole 111 of the body 11, they can prevent leakage. However, when the pick-and-place part 13 is displaced in the third direction, there will be a large frictional force between the two O-rings 151, 152 and the receiving hole 111, so it is not easy to quickly perform retraction displacement or protruding reset in the third direction. Causes the absence of affecting the accuracy of picking and placing electronic components; and when the picking and placing piece 13 is pushed by the reaction force of the electronic component, and the compression spring 14 moves upward in the third direction, the picking and placing piece 13 will be pressed by its own weight and the force of the spring 14. The relatively large downward force formed by the reaction force and the friction force of the two O-rings 151 and 152 presses against the electronic component, so that the electronic component is damaged due to excessive downward force, resulting in the loss of the electronic component that is easy to be damaged; Or, when the two O-rings 151, 152 of the pick-up unit 10 cannot be attached to the inner wall surface of the housing hole 111 of the main body 11 due to deformation or wear after a period of time, the vent 132 of the pick-and-place part 13 will Leaked air, so that the suction nozzle 131 of the pick-and-place part 13 cannot vacuum the electronic components, which in turn affects the material transfer operation, resulting in the lack of inconvenient operation
