Description

Semi-automatic vacuum test tool

Technical field

The present invention relates to a kind of semi-automatic vacuum test tool, relate in particular to the leak resistance measurement jig of a kind of cell phone cameras, computer photography machine.

Background technology

The leak resistance measurement jig of existing cell phone cameras, computer photography machine mainly comprises owing to place the upper die and lower die of test products.In the test process of product; At first test products is placed in the die cavity of patrix, starts power supply then, move through cylinder drive patrix and test products; Fitting to upper die and lower die sealings forms closed chamber, and test products is positioned at closed chamber and can carries out the leak resistance test.Because the location of test products in last model cavity is difficult to hold, be prone to cause that the erroneous judgement of test products causes reporting to the police and suspending; And patrix is fixed through compressive plate and cylinder, when patrix contacts with counterdie, owing to there is not buffer structure, can and place the test products in it to cause damage to whole measurement jig; In addition,, all need cylinder to move upward,, drive very inconvenience of cylinder repeatedly, and seriously reduced detection efficiency because in the test process, it is very frequent manually to change product to picking and placeing of product because test products is placed in the patrix.

Summary of the invention

Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of semi-automatic vacuum test tool that can effectively improve testing efficiency, reduce False Rate, is used for the leak resistance of cell phone cameras, computer photography machine is tested.

Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:

Semi-automatic vacuum test tool comprises support, upper die component, following membrane module, rectilinear motion attitude reference device and test end box; Box and support are fixed at the bottom of the said test; In test end box, be provided with test circuit; Upper side at test end box is provided with the test starting button often opened and the button protection piece that is positioned at the test starting button outside, and circuit is connected between test circuit and the test starting button; Said down membrane module comprises counterdie and tuning plate, and said counterdie is provided with the die cavity of placing test products, in die cavity, is provided with calibrating terminal, and counterdie is fixed on the upper side of test end box through tuning plate, and circuit is connected between calibrating terminal and the test circuit; Said upper die component comprises patrix, compressive plate and cylinder, and the cylinder body of said cylinder is fixed on the support, and its output shaft is vertically fixed towards counterdie and with compressive plate, and patrix is fixed on the side of compressive plate towards counterdie; Said rectilinear motion attitude reference device comprises supporting slide rail and slide block, and said slide rail is fixed perpendicular to counterdie direction and support, and said slide block and compressive plate are fixed; When the air cylinder driven patrix is descending when putting in place, the upper die and lower die sealing is fitted and is formed closed chamber, and compressive plate touches test starting pushbutton enable test circuit.

This measurement jig is placed on test products in the die cavity of counterdie earlier in use, starts cylinder; Let patrix move downward, fit to the upper die and lower die sealing, compressive plate touches test starting pushbutton enable test circuit simultaneously; Can carry out the leakproof test to test products, simple to operate.

Preferably, this measurement jig also comprises counter, and said counter presses number of times to count to the point of test starting button.Every like this detection once, counter will be counted once.

This measurement jig also comprises folding handles, preferably folding handles is fixed on the test end box.

Beneficial effect: semi-automatic vacuum test tool provided by the invention is placed on test products in the counterdie, and passes through the mobile-initiated test circuit of upper die component, simple to operate, stable testing.
