Description

Automatic large-scale pneumatic lift platform of locking

Technical Field

With the increasing market demand, how to improve the productivity is always a key concern for all electronic manufacturers. Improving the efficiency of functional testing is undoubtedly an effective means to shorten the production cycle of the product. Therefore, electronic manufacturers continuously introduce automatic test equipment for improving production efficiency, and integrated automatic test equipment capable of testing multiple products simultaneously is more favored. The integrated test platform has larger volume than a tool which can only test a single product, the carrier plate for placing the product has larger volume and heavier weight, and the problem that how to transport the carrier plate among various work stations and fix the carrier plate at a test position is also solved.

In the existing automatic testing equipment, the testing process generally includes placing the product into the carrier plate, transporting the carrier plate to the vicinity of the testing jig by the transport belt, grabbing the carrier plate by the manipulator and placing the carrier plate into a specific position of the testing jig, and finally moving the carrier plate and the product to the testing position by the testing jig and fixing the carrier plate and the product for testing. For the automatic test equipment which needs to transport large-scale heavy-duty carrier plates, the robot is difficult to grasp the carrier plates with large sizes to keep balance, and the robot occupies a large volume and has high cost. Or some testing equipment adopts a semi-automatic scheme, the support plate is directly placed on the testing jig through manpower, the support plate is moved to a testing position after being fixed by the pneumatic mechanism, and then testing is carried out. The difficulty of this approach is that heavy carrier plates are difficult to transport by hand, and have high requirements on operators. Meanwhile, in the above test scheme, the fixing of the carrier plate on the jig is completed by a mechanism driven independently.

In the face of large and heavy carrier plates required by testing, if full-automatic testing equipment is adopted, in order to meet the requirements of grabbing carrier plates with larger sizes and bearing larger weight, the manipulator needs to be capable of balancing the carrier plates and has higher strength, so that the cost required by the manipulator is greatly increased. If adopt semi-automatization's test equipment, the heavy carrier plate of artifical transport size weight can very consume physical power, has the potential damage product of misoperation a little, therefore operates very difficultly. In addition, no matter the existing full-automatic test equipment or semi-automatic test equipment needs to be provided with a carrier plate fixing module driven independently, the production cost of the test equipment is undoubtedly increased, the fixing action and other actions are independent, a part of time needs to be occupied independently to finish the action, the time required by the test is also increased, and the working efficiency is reduced.

After the test is finished, the carrier plate platform moves upwards under the pushing of the double-rod cylinder 10, meanwhile, the linkage block 9 does not abut against the lower hook of the locking hook 17 any more, under the action of the spring 15, the upper hook of the locking hook 17 starts to rotate in the opposite direction of the carrier plate supporting leg 1, and finally, the upper hook is not located above the bevel groove 61 of the strut 6, namely, the whole carrier plate platform is loosened. This locking mechanism can prevent that the tool from producing the displacement because of the grafting of gas circuit or circuit in the test procedure, and the locking force that leans on the cylinder is not enough, because the cylinder is when receiving great external force, the cylinder pole has certain displacement, causes each grafting module not hard up easily, consequently adds a rigid locking module and is very necessary.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
