Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the device with positive and negative identification comprises a bracket 1 fixed on a workbench on one side of a conveying belt, a lifting driving part 2 is fixed on the top of the bracket 1, an output shaft of the lifting driving part 2 is arranged downwards, a plate-shaped fixing plate 3 is horizontally fixed at the lower end of the output shaft, a plurality of anti-reflection blocks 4 are fixed on the lower side of the fixing plate 3, and the lower end of each anti-reflection block 4 is provided with a convex and/or concave anti-reflection part for being spliced with the top of a workpiece. In this embodiment, the lifting driving member 2 is a cylinder, and a motor and the like can be selected as required; the anti-reverse blocks 4 are all cylindrical, external threads are arranged on the outer sides of the upper ends of the anti-reverse blocks 4, the upper ends of the anti-reverse blocks 4 penetrate through the fixing plate 3 and clamp the fixing plate 3 through nuts in threaded connection with the anti-reverse blocks 4 and are fixed, and the anti-reverse blocks 4 are evenly distributed on the fixing plate 3 along the square shape.

A plurality of guide polish rods 5 are arranged on the support 1 in a penetrating manner along the vertical direction, and the lower ends of the guide polish rods 5 are fixed with the fixing plate 3 and can lift along the vertical direction along with the movement of the fixing plate 3. In this embodiment, the guide polish rod 5 is at least three vertical, and preferably four vertical.

In order to make this take positive and negative discernment device adapt to the different user demands of different positions, main part and the level that straight strip spout was seted up including the top of support 1 set up in the slide at main part top, and the slide is fixed with the main part through the fastener that passes slide and spout, and lift driving piece 2 is fixed on the slide, and a plurality of guide polished rod 5 all wears to establish on the slide. When the position deviation occurs, the fastener can be disassembled, the position of the sliding plate can be adjusted along the length direction of the sliding chute, and then the sliding plate is fixed again by the fastener.

In order to improve the accuracy of reverse recognition, the device with the forward and reverse recognition function further comprises a position sensor, a controller and an alarm, wherein the position sensor is fixed on the support 1 or the lifting driving piece 2 and can detect the descending height of the fixing plate 3, and the controller can receive a reverse signal sent by the position sensor and control the alarm to give an alarm. For example, the position sensor is fixed on one side of the bracket 1 facing the fixing plate 3, and when the lifting driving piece 2 drives the fixing plate 3 to descend to the position sensor, the controller does not control the alarm to give an alarm; on the contrary, when the lifting driving piece 2 drives the fixing plate 3 to move downwards and the position sensor does not detect the fixing plate 3, the workpiece is judged to be reversed, and the controller controls the alarm to give an alarm.

In order to facilitate the operation, the device with forward and backward recognition further comprises an operating button, the operating button and the lifting driving piece 2 are both connected with a controller, and the controller can control the operation of the lifting driving piece 2 when the operating button is operated. And in order to avoid false alarm, a time delay device can be connected to the controller, and when the operation button is pressed and is delayed to set time, the position sensor still does not send a proper signal to the controller, the controller controls the alarm to alarm.

When the device with the forward and reverse identification function is used, a plurality of workpieces are fed to a feeding station below the fixed plate 3, the operating button is pressed, the lifting driving piece 2 drives the fixed plate 3 to descend, whether the workpieces are reversed is identified by the mode that the reverse prevention part at the lower end of each reverse prevention block 4 is inserted into the top of the workpiece, if the workpieces are reversed, the sizes of the reverse prevention parts and the tops of the workpieces are not corresponding, the reverse prevention parts and the tops of the workpieces cannot be inserted into each other, the fixed plate 3 cannot descend to the lowest position, the alarm can be controlled to alarm by the controller to receive signals sent by the position sensor, the condition that the workpieces are reversed can be quickly judged, and the workpiece can be timely adjusted.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
