Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Example 1
A non-contact continuous high-precision length detecting and sorting device comprises: the device comprises a feeding chute 2, a positioning guard ring 3, a positioning material-distributing ratchet 4, a ratchet rotating shaft 5, a sorting valve 6, a left laser range finder 7, a right laser range finder 8 and a detection site 9. The feeding chute 2 and the positioning retainer 3 are fixed; the positioning guard ring 3, the positioning material-distributing ratchet 4 and the ratchet rotating shaft 5 are all cylindrical, and the axes are superposed; the feeding chute 2 is connected at the corresponding connecting position on the circumferential wall of the positioning guard ring 3, the ratchet rotating shaft 5 is fixed relative to the positioning and distributing ratchet wheel 4, the positioning and distributing ratchet wheel 4 rotates along with the ratchet rotating shaft 5, when the ratchet rotating shaft 5 drives the positioning and distributing ratchet wheel 4 to rotate clockwise, the product 1 in the feeding chute 2 enters the cylindrical groove on the positioning and distributing ratchet wheel 4 and is limited by the inner ring of the positioning guard ring 3, and therefore the product moves along with the rotation of the positioning and distributing ratchet wheel 4. The left laser distance measuring instrument 7 and the right laser distance measuring instrument 8 measure the distance between two ends of the product 1.
Example 2
Left laser range finder 7, right laser range finder 8 rely on the laser irradiation to carry out non-contact's detection at two terminal surfaces of product, and the measurement accuracy can reach 0.001mm at the highest. The method comprises the following specific steps: calibrating the length by using a standard product with the actual length of X +/-0.005 mm, irradiating two end faces of the standard product by using a left laser range finder 7 and a right laser range finder 8 to obtain two values of Y and Z, calculating Y-Z as M, wherein M is the relative detection length, and setting M as X; when a common product moves to a detection position, the left laser range finder 7 and the right laser range finder 8 irradiate the end faces of the two products to obtain two values Y1 and Z1, the system automatically calculates Y1-Z1 to M1, then calculates the value of M-M1 to t1, the actual length of the product is X + t1 at the moment, and the like, and the actual lengths of the rest products are obtained through measurement.
When the product 1 moves to a detection position along with the rotation of the positioning material distribution ratchet wheel 4, the left laser range finder 7 and the right laser range finder 8 detect the length of the product, and the system automatically compares the detected length with a qualified value set by the system to obtain whether the length of the product 1 is qualified. Unqualified products are transmitted to the sorting valve 6, the sorting valve 6 is opened, and the unqualified products fall out; qualified products are conveyed to the position of the sorting valve 6, and the sorting valve 6 is not opened until the left lower end leaves from the opening. Thereby completing the length detection and sorting.
Example 3
Product A divides material ratchet 4 through the location that feeding spout 2 got into 3 inner circles of location protective shroud, through product A self gravity, drives ratchet pivot 5 and rotates, then when detecting the position, left laser range finder 7, right laser range finder 8 detect the length at product A both ends, the standard numerical range of contrast reference. The product A continues to move to the distributing opening 6. As shown in figure 3, when the product A reaches the position 70 degrees shown in the figure at the lower end of the device, the sorting valve 6 rotates anticlockwise to the right side to open, and when the next qualified product reaches the position 70 degrees shown in the figure, the sorting valve 6 rotates anticlockwise to close to the left side. As shown in fig. 4, after product a exits the apparatus from the sorting gate, product a of unacceptable length exits the apparatus from the sorting gate 6 and product B, C, D of acceptable length exits from the lower left-hand notch position.
