Technical Field
[0001] This utility model relates to the field of quality testing equipment, specifically a differential distance adjustment device. Background Technology
[0002] Many manufacturing industries are placing increasingly higher demands on the quality control of the precision parts they process. Currently, during component 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 component appearance, quality defects, and critical dimensions is now largely achieved through rapid screening using visual inspection equipment. Materials to be inspected are transported to the visual inspection area, where the inspection camera transmits the captured image data to a computer for analysis and comparison, selecting qualified components.
[0003] Current visual inspection methods require placing a single material to be inspected at the center of the inspection equipment's field of view, ensuring no other materials interfere. Furthermore, due to the use of assembly line inspection, materials need to be arranged with appropriate spacing between them. Therefore, a device is needed that can adjust the speed at which the material enters the inspection device's field of view. Utility Model Content

Detailed Implementation
[0020] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.
[0021] Embodiments of this utility model, such as Figures 1 to 6 A differential distance adjustment device is provided, including a conveying mechanism, a distance adjustment mechanism, and a guiding module. When the material to be tested is driven on the conveying mechanism and passes through the guiding module, it is guided and diverted to the distance adjustment mechanism. The distance adjustment mechanism adjusts the distance between the material to be tested before and after by adjusting the operating conveying speed.
[0022] Specifically, the conveying mechanism includes a conveyor belt 3 and a conveyor motor 31. The conveyor motor 31 drives the conveyor belt 3. The conveyor belt 3 is mounted on the base 1 via rotating rollers. The conveying mechanism moves the material to be tested to the position of the guide module.
[0023] The distance adjustment mechanism includes a connecting conveyor belt 5 and a conveyor motor 4. The connecting conveyor belt 5 is located outside the guide module, and the conveyor motor 4 drives the connecting conveyor belt 5 to rotate. The pressure roller 51 is fixedly mounted on the frame by a fixing bracket. The conveyor motor 4 is equipped with a driver, and the start, stop, and speed of the conveyor motor 4 are controlled by a control system. The connecting conveyor belt 3 is rotatably mounted on the mounting frame 6 via a drive roller. Preferably, the output shaft of the conveyor motor 4 is coaxially provided with synchronous teeth, and the synchronous teeth are also coupled with a synchronous toothed belt, the other end of which is connected to the drive roller. The connecting conveyor belt 5 is light-transmitting, which facilitates background illumination of the material to be detected on the connecting conveyor belt 5 by a light source positioned below the detection module 73. The distance adjustment mechanism also includes a pressure roller 51, which is mounted on the mounting frame 6 and rolls from above the connecting conveyor belt 5, abutting against the upper surface of the connecting conveyor belt 5.
[0024] The guiding module includes a guide turntable 2, a guide wheel motor mounting platform 21, a guide wheel motor mounting plate, and a guide wheel drive motor 22. The guide turntable 2 is rotatably mounted above the conveyor belt 3, and the connecting conveyor belt 5 is provided on the side of the guide turntable 2. The guide shaft of the guide turntable 2 is connected to the guide wheel drive motor 22. Specifically, the guide wheel drive motor 22 drives the guide shaft through a height coupling, and a connecting block is sleeved at the bottom of the guide shaft. The guide turntable 2 is fixed to the bottom of the connecting block with screws. The guide wheel motor mounting platform 21 is located above the guide turntable 2, and a guide wheel motor mounting plate is mounted on the guide wheel motor mounting platform 21. The guide wheel drive motor 22 is mounted on the guide wheel motor mounting plate. The guide wheel drive motor 22 controls the rotation state of the guide turntable 2 by adjusting its speed. A guide plate 23 is provided on the outer side of the feed turntable 2. The guide plate 23 assists the material to be tested in adjusting its movement direction at the rear of the feed turntable 2.
[0025] As needed, when a person skilled in the art sets up one set of the guiding modules, the guiding module is configured with a guiding component on only one side to guide the material to be tested onto the connecting conveyor belt 5 on one side. When two sets of the guiding modules are set up, such as Figure 1-3 As shown, the guiding components are arranged in opposite directions from the center, guiding the detected materials to separate from the center and onto the connecting conveyor belt 5 on the side closest to them. Those skilled in the art can adjust the above settings to match the width of the guiding module and the conveyor belt according to their needs; further details are omitted here.
[0026] A production line working device for use with the differential distance adjustment device includes a hoist 7, which is equipped with a hopper, a lifting belt, and a lifting motor. The hopper is positioned at the initial position of the diversion and return device, and is bucket-shaped, with its upper part connected to the screening module. The bottom of the lifting belt is located in the lower part of the hopper, and its top is located on the upper part of the screening module. The lifting belt lifts the material to be tested to the initial position of the screening module. The lifting motor drives the lifting belt.
[0027] The screening module includes a height screening mechanism 71 and a horizontal screening mechanism 72. The height screening mechanism 71 includes a baffle plate and a baffle support. The baffle plate is mounted above the conveying mechanism via the baffle support. The gap between the baffle plate and the conveying mechanism is adjusted to the height of the material to be tested in the detection direction, so as to block materials to be tested that are stacked beyond the height of a single workpiece.
[0028] The horizontal screening mechanism 72 includes a mounting frame 6, a guiding unit, and a diversion unit. The guiding unit includes a guide block, which is mounted on one end of the mounting frame 6. The guide block is positioned in front of the direction in which the material to be tested is driven by the conveying mechanism. The bottom of the guide block is lower than the height of the material to be tested in the detection direction than the height of the material to be tested. A guide ramp is provided on the side of the guide block, which guides the material to be tested to the diversion unit. The diversion unit includes a diversion block, and the side of the diversion block and the edge of the conveying mechanism have a width space that allows only a single piece of material to be tested to pass through in the horizontal direction. Any other material exceeding the width of a single piece of material to be tested is pushed away from the edge of the conveying mechanism and reaches the return mechanism.
[0029] 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.
[0030] Working process: First, the material to be tested is fed into the hopper of the elevator 7. The elevator 7 lifts the material to be tested onto the conveying mechanism. The conveying mechanism moves the material to be tested to the screening module. As it passes through the screening module, stacked or contacting materials that might 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 23. Then, driven by the conveying mechanism, it falls onto the connecting conveyor belt 5 along the guiding direction of the guide plate 23. It is then tested by the testing module 73, and finally classified according to quality.
[0031] This device is fixedly installed at the installation position on the inspection production line. The specific dimensions and error range of the material to be inspected are input into the control unit. The control unit generates specific control commands, which are then used to transport the material at a preset speed via the connecting conveyor belt 5. The speed of the connecting conveyor belt 5 is greater than that of the conveyor belt 3, facilitating image acquisition and inspection by the visual inspection device within the inspection module 73. When the needs of the inspection module 73 are met, the running speed of the connecting conveyor belt 5 can be adjusted to increase or decrease, causing the distance between adjacent materials to be inspected that fall along the guide belt 5 to change accordingly, facilitating subsequent inspection and classification module 74 operations.
[0032] 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.
[0033] 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.
