Adjustable-type precise sorting fixture

Abstract

The invention relates to an adjustable-type precise sorting fixture. The adjustable-type precise sorting fixture comprises a fixture loading plate, a driving mechanism, an adjusting mechanism and twoor more grabbing units, wherein the driving mechanism, the adjusting mechanism and the two or more grabbing units are arranged on the fixture loading plate. The driving mechanism is arranged on the fixture loading plate. The adjusting mechanism comprises a guiding plate sliding on the fixture loading plate. The driving mechanism drives the guiding plate to slide along the Z axis in a reciprocatingmode. Each grabbing unit comprises a transplanting bracket sliding on the fixture loading plate. The guiding plate is provided with guiding grooves matched with the grabbing units. The transplantingbrackets are provided with adjusting action parts. The adjusting action parts slide in the guiding grooves in a reciprocating mode. When the guiding plate slides along the Z axis, one or more grabbingunits simultaneously slide along the Y axis in the same direction under the traction action of the guiding grooves on the adjusting action parts, and all the grabbing units are close to or away fromone another. According to the adjustable-type precise sorting fixture, all the grabbing units can simultaneously slide in the same direction, the position adjustment effect that the grabbing units areclose to or away from one another is achieved, the adjustable-type precise sorting fixture can effectively adapt to different types of workpieces, and universality and practicability are high.

Description

technical field [0001] The invention relates to a robot fixture, in particular to an adjustable precision sorting fixture. Background technique [0002] For the grasping work in the PCB board production process, the existing technology is to observe with the naked eye first, and then grasp it with bare hands. In the actual grasping process, the rhythm of grasping is required to be relatively fast, so it is difficult for manual grasping to keep up with the rhythm. It leads to low output, and workers need to carry out grasping work for a long time, resulting in high labor intensity of workers; in order to solve the above-mentioned problems of low output, failure to keep up with the pace and high labor intensity, the existing solutions are generally by sending additional workers to Increase throughput, keep up with picking tempo, and share labor, but at the expense of increased labor costs. With the development of the industry, it is the general trend for robots to replace wor...

[0002] For the grasping work in the PCB board production process, the existing technology is to observe with the naked eye first, and then grasp it with bare hands. In the actual grasping process, the rhythm of grasping is required to be relatively fast, so it is difficult for manual grasping to keep up with the rhythm. It leads to low output, and workers need to carry out grasping work for a long time, resulting in high labor intensity of workers; in order to solve the above-mentioned problems of low output, failure to keep up with the pace and high labor intensity, the existing solutions are generally by sending additional workers to Increase throughput, keep up with picking tempo, and share labor, but at the expense of increased labor costs

With the development of the industry, it is the general trend for robots to replace workers. Therefore, some robot fixtures for grabbing PCB boards have gradually appeared in the market to increase production and realize automated work. However, due to the variety of PCB board models, different types of PCB boards The board shapes are different, including: 45*30~6*8mm, 45~200*6~30, 200*200~80*80 and other sizes, so it is difficult for the current robot fixture to meet different needs. Replacement or adjustment Change the position of the suction cup to adapt to different types of PCB boards, but each replacement or adjustment needs to be stopped and done manually, which is troublesome to operate and has certain safety hazards
