Description

Manual optical coupling type shield cover flatness detection instrument

Technical Field

The utility model belongs to the technical field of the metal product detects and specifically relates to shield cover flatness detection equipment.

Background

At present, a shielding case manufacturer needs to detect the flatness of the shielding case before shipment, and part of the detection process is seen by artificial eyes and the other part is detected by an optical coupling type automatic detection machine. The manual detection is easy to have misjudgment, and has low precision and low efficiency. The automatic machine table is used, the occupied plant area is large, the operation and debugging are complex, the product replacement is troublesome, the problems in the use process are not easy to be eliminated by general operators, and the dependence on related technicians in the machine table production process is strong. This increases the machine use and maintenance costs. In the general development and production of the shielding case, small-batch proofing is firstly carried out, and then batch production is carried out, during the proofing period, because of multiple product types, the replacement is frequent, a great deal of time is consumed in the debugging process, the capacity of an automatic machine cannot be fully exerted, and the risk of defective product outflow exists when the manual detection efficiency is low. In addition, the shielding cover has various sizes, the automatic machine with strong universality is high in price, the debugging is more troublesome, and the automatic machine with low universality is too small or too large, or the product which is not suitable for automatic conveying cannot be used. With the gradual rise of labor cost and rent of factory buildings, the cost pressure of small and medium-sized shielding case manufacturers in the detection link is higher and higher.

Disclosure of Invention

For solving the shield cover and detecting the link, the erroneous judgement appears easily in artifical measuring, and the precision is low, and is inefficient, and the automatic board occupies factory building area big, and the operation debugging is complicated, changes the trouble scheduling problem of product, the utility model designs a manual opto-coupler formula shield cover plane degree detecting instrument.

The utility model provides a technical scheme that its technical problem adopted is: install computer accessories and detecting system accessory integration in a mainframe box, detection achievement platform passes through hinge connection with the mainframe box, expandes when using, and the time spent is folding more. The keyboard, the mouse and the detection jig are placed in the detection workbench, covered by two rotatable flat plates and locked by a door stopper. Go up unloading by the manual work, use opto-coupler detecting system to detect. During operation, an operator puts the shielding case into a fixture in the middle of the detection workbench, the instrument rapidly detects the shielding case, after detection is completed, a detection result is displayed, and when the detection result is OK, a sound is made. The product of not good getting of part is released through the push rod of tool bottom, and operating personnel places the shield cover according to instrument cue signal classification, just accomplishes the testing process. 4 groups of mounting holes are designed at the mounting positions of the jigs, enough space is reserved around the mounting holes, and the design size of the middle hole of the cover plate of the workbench is larger and the jigs with different sizes are compatible.

The beneficial effects of the utility model are that, as long as operating personnel puts and waits to detect the shield cover and get into detection tool, opto-coupler detecting system accomplishes the detection voluntarily to output shows the testing result signal, operating personnel takes away classification according to the detected signal and just accomplishes the testing process. The operation is simple, the precision is high, the efficiency is high, when the product is to be replaced, the operation bedplate is opened, the jig screws are loosened, the corresponding jig is installed, and the operation bedplate is turned over again to complete the product replacement work. And a complex debugging process is not needed, and the product can be quickly replaced. When the instrument is not used, the workbench can be turned by 90 degrees and combined with the instrument host, so that the space is saved, and dust pollution is prevented. The workstation can install the tool of equidimension not, and the instrument is compatible strong, and is with low costs. The keyboard cover plate and the operation table plate which can be turned over are used as the operation table top, so that the use is convenient, and the efficiency is improved.
