2 sets of light curtains are mounted on servo platform two sides by the utility model, and servo platform detects product movement to needs Point, computing controller root Ju product blocks the amount of light curtain, automatic to calculate product width value, essence in the case where not contact product It spends up to 0.002mm, is 5~10 times of traditional detection method precision, because using servo platform, speed is also traditional detection method 3 times, and can be detected with multiple spot.It is applicable to any wide detection of 3C Product shell, and is not influenced by bloom or transparent material.
The human-computer interaction interface includes the control button being arranged in the control cabinet shell and measures number for showing According to LED display.
The bracket is hollow bracket, is equipped with conducting wire in the bracket.
The article carrying platform is the plate body that top view is I-shaped.
The fixture is four clips, and the front-end and back-end of the article carrying platform are respectively provided with two.
The transmitter copper is bolted on the bracket and the connecting plate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the top view of the utility model servo platform;
Fig. 3 is the partial circuit block diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of light curtain measuring device, including light curtain device 1, servo platform 2 and control cabinet 3, it watches Take platform 2 include an article carrying platform 21 and one be connected with driving motor 22 shaft 23, be equipped with for solid above article carrying platform 21 The fixture 24 of fixed shell to be measured, the lower section of article carrying platform 21 are fixed with a sliding block 25, and 23 connection sliding block 25 of shaft simultaneously passes through sliding block 25 driving article carrying platforms 21 are moved forward and backward;The two sides of servo platform 2 are fixed with two vertical brackets 4, the top of two brackets 4 It is fixed with two pieces of connecting plates 41;Light curtain device 1 includes two transmitters 11 and two receivers 12, every bracket 4 and two pieces of companies A transmitter 11 is fixed between fishplate bar 41, receiver 12 is arranged on servo platform 2, and is located at the underface of transmitter 11;It drives Dynamic motor 22 connects control cabinet 3 by conducting wire with light curtain device 1, and control cabinet 3 connects a power supply by the power supply line with plug; Control system 5 is equipped in control cabinet 3, control system 5 includes computing controller 51, programmable controller 52 (PLC) and man-machine friendship Mutual interface 53, light curtain device 1 connect the signal input part of computing controller 51, the signal output end connection of computing controller 51 PLC 52, driving motor 22 connect PLC 52, the connection human-computer interaction interface 53 of PLC 52.
