Description
Technical Field
[0001] This utility model relates to the field of quality inspection equipment, specifically a workpiece diversion and return device for quality inspection equipment. Background Technology
[0002] With the improvement of domestic manufacturing level and the intensification of market competition, many manufacturing industries have put forward increasingly higher requirements for the quality control of the precision parts they process. Currently, during parts inspection, inspectors need to perform full-dimensional measurements on the parts, that is, 100% inspection of the product to achieve product quality control. Usually, due to the low efficiency and large error of manual inspection, its adaptability is not high when mass production. Under such circumstances, the current inspection of the appearance, quality defects and key dimensions of parts is mostly carried out by visual inspection equipment for rapid identification and screening. The products to be inspected are transported to the visual inspection area by a transportation agency, and then the installed camera captures the image projected onto the surface of the part to be tested by a laser emitter and deformed by surface modulation. The camera transmits the captured image data to a computer for analysis and comparison processing, and the qualified parts are screened out.
[0003] Existing testing devices often experience accumulation issues when handling materials, especially annular or sheet-shaped materials such as sealing rings and gaskets, entering the testing area, affecting testing accuracy. Therefore, sieving is required based on the material's entry state. However, materials in unsuitable positions after sieving need to be returned to their starting point, impacting testing efficiency and pace. Furthermore, the sieving device's specifications or position need to be adjusted to handle materials of different sizes. Therefore, a workpiece diversion and return device is needed that can efficiently sieve materials in suitable positions, promptly return excess materials to their initial position, and be easily adjustable for different batch sizes.

Detailed Implementation
[0024] 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.
[0025] Embodiments of this utility model provide, as follows: Figures 1 to 7 A workpiece diversion and return device for quality inspection equipment is provided, including a lifting module, through which the material to be inspected is lifted into a screening channel, and a screening module, through which individual materials to be inspected are screened out and allowed to pass to the next position, while the remaining workpieces return to the initial position of the lifting module.
[0026] Specifically, the lifting module includes a lifting machine 1, which is equipped with a hopper 11, a lifting belt 12, and a lifting motor 13. The hopper 11 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 12 is located inside the lower part of the hopper 11, and its top is located above the screening module. The lifting belt 12 lifts the material to be tested to the initial position of the screening module. The lifting motor 13 drives the lifting belt 12.
[0027] The screening module includes a conveying mechanism, a height screening mechanism, a horizontal screening mechanism, and a return mechanism. The conveying mechanism carries the material to be tested, lifted by the lifting module, forward. The conveying mechanism includes a horizontal conveyor belt 2 and a conveyor drive motor 21, which drives the horizontal conveyor belt 2.
[0028] The height screening mechanism includes a baffle plate 3 and a baffle support 31. The baffle plate 3 is set above the conveying mechanism through the baffle support 31. The gap between the baffle plate 3 and the conveying mechanism is adjusted to the height of a single 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.
[0029] The horizontal screening mechanism includes a separator mounting plate 43, a separator bracket 4, a guide unit, a diversion unit, and an adjustment unit. The separator mounting plate 43 is mounted on the frame, and the separator bracket 4 is fixedly mounted below the separator mounting plate 43.
[0030] The guiding unit includes a guide block 41, which is fixedly installed on the feed end of the separator bracket 4 facing the material to be tested. Specifically, the guide block 41 is positioned in front of the material's running direction, driven by the conveying mechanism. The height distance between the bottom of the guide block 41 and the running surface of the conveying mechanism is less than the height of the material in the testing direction. A guide ramp 411 is provided on the side of the guide block 41, which guides the material to be tested to the diversion unit position.
[0031] The diversion unit is equipped with a material distribution plate 42. The side of the material distribution plate 42 and the edge of the conveying mechanism have a width space in the horizontal direction that allows only a single material to be tested to pass through. Other materials to be tested that exceed the width of a single material to be tested are pushed away from the edge of the conveying mechanism and reach the position of the return mechanism.
[0032] The adjustment unit includes a height adjustment unit and a width adjustment unit. The height adjustment unit includes a support rod 45 and adjusting screws 44. The separator mounting plate 43 is mounted on the frame via the adjusting screws 44. The support rod 45 is vertically fixed below the separator mounting plate 43, and the separator bracket 4 is fixedly sleeved onto the support rod 45. The height and level of the separator mounting plate 43 are adjusted by adjusting the four sets of adjusting screws 44, thereby adjusting the height of the separator bracket 4.
[0033] The width adjustment unit includes a width adjustment screw 5 and a width adjustment motor 51. The width adjustment motor 51 is disposed on the side of the separator bracket 4 and is connected to the width adjustment screw 5. The width adjustment screw 5 is threadedly connected to a screw nut 54 fixed above the material distribution plate 42. The material distribution plate 42 is simultaneously sleeved on a guide optical shaft 52, which is fixedly disposed within the separator bracket 4 and is parallel to the width adjustment screw 5. The width adjustment motor 51 drives the material distribution plate 42 to move horizontally along the direction of the guide optical shaft 52, thereby enabling the width adjustment screw 5 to adjust the distance between the material distribution plate 42 and the edge of the conveying mechanism through the width adjustment motor 51.
[0034] The reflux mechanism includes a reflux conveyor belt 6 and a reflux motor 61. The reflux conveyor belt 6 is driven by the reflux motor 61. The feed end of the reflux conveyor belt 6 is arranged parallel to the material distribution plate 42. The discharge end of the reflux conveyor belt 6 is arranged above the lifting module, specifically, the discharge end of the reflux conveyor belt 6 is located above the hopper 11.
[0035] The reflux mechanism also includes a reflux baffle 62, which is mounted on the frame and above the reflux conveyor belt 6. The reflux baffle 62 blocks the diverted material to be tested, preventing it from deviating from the equipment due to excessive speed, and guides the blocked workpiece onto the reflux conveyor belt 6.
[0036] Example 2, based on the technical solution of Example 1, describes a screening module that forms two detection lines through flow diversion. The guide block 41 in the guide unit, fixedly installed on the separator bracket 4, includes two symmetrically arranged guide ramps 411, guiding the material to be detected to the diversion unit. The diversion unit includes two symmetrically arranged distribution plates 42, with a distance adjustment unit between them. The distance adjustment unit includes a width adjusting screw 5 and a width adjusting motor 51. The width adjusting screw 5 is located at the lower part of the separator bracket 4, with the threads of the two width adjusting screws 5 having opposite directions, and connected by a coupling 53. The width adjusting screw 5 is threadedly connected to a screw nut 54 fixedly installed on the corresponding distribution plate 42. The distribution plate 42 is simultaneously sleeved on a guide optical shaft 52, and moves along the direction of the guide optical shaft 52. The width adjustment motor 51 is connected to the width adjustment lead screw 5, and the width adjustment motor 51 synchronously controls and adjusts the distance between the material distribution plate 42 and the edge of the conveying mechanism.
[0037] The reflux mechanism is located on both sides of the screening module, and the two sets of reflux mechanisms on both sides are respectively connected to the hopper 11.
[0038] Usage: Preferably, taking an annular sealing ring as an example, the material to be tested is lifted by the elevator 1 and placed onto the horizontal conveyor belt 2. The horizontal conveyor belt 2 moves the material to be tested. When the material to be tested passes through the height screening mechanism, the material to be tested that is stacked together and exceeds the height limit of the baffle 3 will be blocked from moving forward by the baffle 3, thereby separating it from the bottom layer of material to be tested and blocking the blank space between the materials falling onto the horizontal conveyor belt 2, thus realizing the passage of a single layer of material to be tested through the height screening mechanism.
[0039] When the material to be tested is driven to the horizontal screening mechanism, it first comes into contact with the guide block 41. As the material to be tested continues to move, the guide block 41 and the two sides of the horizontal conveyor belt 2 gradually narrow. At this time, part of the material to be tested in the same layer is squeezed by the guide block from the horizontal direction, and thus falls to the return mechanism. It is then re-transported by the return conveyor belt 6 and put into the hopper 11.
[0040] By pre-adjusting the distance between the edge of the distribution plate 42 and the edge of the horizontal conveyor belt 2, a width is formed at this position that allows a single piece of material to be tested to pass through. At this time, excess material to be tested on the same row is squeezed and falls to the return mechanism, is re-transported by the return conveyor belt 6 and put into the hopper 11.
[0041] 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.
[0042] 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.
