Description
Technical Field
[0001] This utility model relates to the field of quality inspection equipment, specifically a bidirectional guiding device with adjustable distance and height. Background Technology
[0002] Many manufacturing industries are placing increasingly higher demands on the quality control of the precision parts they process. Currently, during part inspection, inspectors need to perform full-dimensional measurements, i.e., 100% inspection of the product, to achieve quality control. However, manual inspection is often inefficient and prone to errors, resulting in poor adaptability for mass production. In this context, the inspection of parts' appearance, quality defects, and critical dimensions is now largely achieved through rapid screening using visual inspection equipment. The material to be inspected is transported to the visual inspection area by a transport mechanism. Then, a camera captures images projected onto the surface of the part by a laser emitter, which are then distorted by surface modulation. The camera transmits the captured image data to a computer for analysis and comparison, allowing qualified parts to be selected.
[0003] Current visual inspection methods aim to place a single material to be inspected at the center of the inspection equipment's field of view. Therefore, a device is needed that can adjust the material to be inspected to be positioned along the path of the visual inspection equipment's center of field of view. Utility Model Content

Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Embodiments of this utility model, such as Figures 1 to 6 A bidirectional guiding device with adjustable distance and height is provided, including a flow guiding module and a speed regulating module. When the material to be tested passes through the flow guiding module, it is driven by friction to adjust its forward direction.

[0028] The distance adjustment unit includes a distance adjustment motor 4, a reducer 41, a coupling 42, a lead screw 43, a transmission nut 44, and a guide block 45. The distance adjustment motor 4 is mounted on the base 1, located between the two direction adjustment units. The reducer 41 is a dual-output reducer 41, with its two output shafts facing each other. The input end of the reducer 41 is connected to the distance adjustment motor 4, and the two output shafts of the reducer 41 respectively drive the direction adjustment units on both sides. The output shafts of the reducer 41 transmit power to the corresponding lead screws 43 via the coupling 42.

[0029] The speed control module includes a connecting conveyor belt 5, a conveyor motor, and a pressure roller 51. The connecting conveyor belt 5 is located outside the direction adjustment unit. The conveyor motor drives the connecting conveyor belt 5 to rotate. The pressure roller 51 is mounted on the frame and abuts against the connecting conveyor belt 5 from above.
[0030] It also includes a conveying device, which includes a conveyor belt 6 and a conveyor motor 61. The conveyor motor 61 drives the conveyor belt 6, and the conveying device moves the material to be tested to the position of the flow guiding module.
[0031] A production line working device for use with the aforementioned height-adjustable bidirectional guiding device includes a hoist 7, which is equipped with a hopper, a lifting belt, and a lifting motor.

The side of the diversion block and the edge of the conveying mechanism are provided with a width space to allow only a single piece of material to be tested to pass through in the horizontal direction. Other materials exceeding the width of a single piece of material to be tested are pushed away from the edge of the conveying mechanism and reach the return mechanism.
[0034] The system also includes a detection module 73, which comprises a sensor and a detector. The detector uses image recognition to detect the material to be tested on the connecting conveyor belt 5 below it. The sensor is positioned in front of the detector to sense the arrival of the material to be tested. After detection, the material to be tested is classified and categorized by a classification module 74 according to the detection results. The technical solutions of the detection module 73 and the classification module 74 are well known to those skilled in the art and will not be described in detail here. The material to be tested is typically a gasket, washer, or sealing ring.
[0035] Working process: First, the material to be tested is placed into the hopper of the elevator 7. The elevator 7 lifts the material to be tested onto the conveying device. The conveying device moves the material to be tested to the screening module. During screening, stacked or contacting materials that may affect the testing are separated. At this point, a single piece of material, upon contact with the guide turntable 2, is subjected to the combined forces of friction and the conveying direction, moving to the guide plate 24. Then, driven by the conveying device, it falls onto the connecting conveyor belt 5 along the guiding direction of the guide plate 24. It is then tested by the testing module 73, and finally sorted and stored according to its quality.
[0036] This guiding device is fixedly installed at the installation position of the inspection production line. Then, the specific dimensions and error range parameters of the material to be inspected are input into the control unit. The control unit then generates specific control commands, and the distance adjustment motor 4, as specified in the control commands, rotates to make the guide turntable 2 reach the designated guiding position. At the same time, the guide wheel drive motor 23 drives the guide turntable 2 to rotate, thereby moving the product passing through this point to the optimal inspection area on the connecting conveyor belt 5, and then conveying it at a preset speed via the connecting conveyor belt 5.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
