Description

Technical Field

[0001] This utility model relates to the field of industrial testing equipment, and in particular to an automatic stud testing machine. Background Technology

[0002] In modern industrial production, studs are widely used basic components, and their quality inspection is crucial. Traditional stud inspection methods reveal many drawbacks when dealing with studs of different lengths, such as short screws and long bolts.

[0003] Currently, when switching between testing studs of different lengths, operators have to manually replace the receiving frame or adjust the equipment structure. Because the receiving frames vary in height, it's difficult to accurately align them with the feed inlet during operation. This easily leads to material spillage due to minor operational errors, causing waste, significantly impacting production efficiency, and increasing production costs. Furthermore, frequent manual intervention and equipment adjustments can easily lead to inconsistent testing standards due to human factors, thus affecting product quality stability. Therefore, an automatic stud testing machine is proposed.

[0004] With the trend of industrial production towards automation and efficiency, there is an urgent need for an automatic stud detection machine that can automatically detect studs of different lengths, avoid frequent manual replacement of receiving frames or adjustment of equipment structure, and accurately connect to the material inlet to prevent material spillage, so as to improve the efficiency and accuracy of stud detection and ensure the continuity and stability of production. Utility Model Content

Example

[0034] Please see Figure 1-5 An automatic stud inspection machine, comprising:

[0035] Rack 1;

[0036] The feeding mechanism is mounted on frame 1;

[0037] The visual inspection mechanism 2 is located on one side of the feeding mechanism, and its bottom is provided with a discharge port 3;

[0038] The height adjustment assembly includes a fixed plate 4 and a lifting mechanism 6. The lifting mechanism 6 is symmetrically arranged on both sides of the frame 1 and connected to the fixed plate 4.

[0039] The receiving frame 5 is detachably installed on the fixing plate 4 and is located directly below the discharge port 3.

[0040] The automatic stud inspection machine of this application is mainly composed of a frame 1, a vision inspection mechanism 2, a discharge port 3, a fixing plate 4, a receiving frame 5, and a lifting mechanism 6. The following is a detailed description of its structure and working principle.

[0041] I. Detailed Structure and Connection Methods of Each Component

[0042] Equipment Assembly: Install and secure the frame 1 as the basic support structure. Install the feeding mechanism on the frame 1 to stably and accurately transport the studs to the inspection position. Install the vision inspection mechanism 2 on one side of the feeding mechanism, ensuring the accurate positioning of the outlet 3 of the vision inspection mechanism 2, which includes both a waste outlet and a qualified product outlet. Symmetrically arrange the lifting mechanism 6 on both sides of the frame 1, with its fixed end firmly connected to the frame 1 and its telescopic end connected to the fixed plate 4 via guide blocks 7. The guide blocks 7 can move along the outside of the frame 1 to ensure the smoothness of the lifting process of the fixed plate 4.

[0043] A parallel slide rail 401 is installed on the upper surface of the fixed plate 4. A groove is provided at the bottom of the receiving frame 5 to cooperate with the slide rail 401, so that the receiving frame 5 can slide smoothly along the slide rail 401. A limiting plate 9 is installed at the front end of the fixed plate 4. A first magnetic suction member 10 is installed on the inner side of the limiting plate 9. A second magnetic suction member 11 that cooperates with the first magnetic suction member 10 is installed at the rear end of the receiving frame 5. The receiving frame 5 is inserted into the fixed plate 4 by cooperating with the parallel slide rail 401 on the fixed plate 4 through its bottom groove. At this time, the first magnetic suction member 10 and the second magnetic suction member 11 attract each other magnetically, positioning the receiving frame 5 on the fixed plate 4 and directly below the discharge port 3. The receiving frame 5 consists of a main frame and a side frame plate 501 connected to the main frame by a hinge. The main frame is provided with a positioning hole, and the side frame plate 501 is provided with a positioning rod 502 that cooperates with the positioning hole.

[0044] A weight sensor 8 is integrated on the fixed plate 4, and the weight sensor 8 is connected to the alarm module of the control system.

[0045] The alarm threshold setting for the weight sensor 8 is as follows: Based on the capacity of the receiving frame 5 and the approximate weight of the studs, the alarm threshold of the weight sensor 8 is set through the control system. For example, the weight of the empty receiving frame 5 is first measured, and then the weight value when fully loaded is calculated based on the maximum number of studs that the receiving frame 5 is expected to hold and the average weight of a single stud. On this basis, an appropriate adjustment is made, such as reserving a certain margin to prevent false alarms, and the adjusted weight value is set as the alarm threshold.

[0046] Material and Magnetic Force Requirements for Magnetic Components: The first magnetic component 10 and the second magnetic component 11 can be made of neodymium iron boron permanent magnet material. This material has the characteristics of high remanence, high coercivity, and high energy product, providing a strong and stable magnetic force. Regarding the magnetic force requirements, it must be ensured that under normal operating conditions, the receiving frame 5 can be firmly attached to the fixing plate 4 and will not fall off due to vibrations during equipment operation. Simultaneously, when it is necessary to remove the receiving frame 5, the operator should be able to apply appropriate external force, such as a force that can be easily pulled by hand. The specific force can be adjusted based on actual operating experience to overcome the magnetic force and pull it out.

[0047] II. Working Principle

[0048] Inspection and feeding: The feeding mechanism slowly conveys the stud to the vision inspection mechanism 2 for inspection. The vision inspection mechanism 2 inspects and judges various parameters of the stud, such as length, diameter, and appearance defects.

[0049] Material discharge and receiving: If the visual inspection mechanism 2 determines that the stud is unqualified, the inspection software controls the corresponding actuator to directly discharge the unqualified stud from the waste port in the discharge port 3 into the corresponding receiving frame 5. The qualified stud is brought out from the qualified product port in the discharge port 3 and falls into the corresponding receiving frame 5. There are multiple receiving frames 5 to collect both unqualified and qualified studs.

[0050] Weight monitoring and alarm: The weight sensor 8 monitors the weight of the studs in the receiving frame 5 in real time. When the weight of the studs in the receiving frame 5 reaches the preset alarm threshold, the weight sensor 8 sends a signal to the alarm module of the control system. The alarm module then issues an alarm prompt, such as an audible and visual alarm, to remind the operator that the receiving frame 5 is about to be filled.

[0051] Material receiving frame 5 replacement: After receiving the alarm, the operator controls the telescopic end of the lifting mechanism 6 to move the fixed plate 4 up and down, causing the material receiving frame 5 to move away from the discharge port 3. When the material receiving frame 5 moves to the appropriate position, the restriction on it is released, such as overcoming the magnetic force between the first magnetic suction component 10 and the second magnetic suction component 11, and the operator pulls the material receiving frame 5 outward. The side frame plate 501 of the material receiving frame 5 is connected to the main frame through a hinge. After being pulled out, the fixing of the positioning rod 502 to the side frame plate 501 can be released, and the side frame plate 501 can be flipped open to facilitate the discharge of materials. Then, the empty material receiving frame 5 can be inserted through its bottom groove, aligned with the parallel slide rail 401 on the fixed plate 4, until it is on the fixed plate 4. At this time, the first magnetic suction component 10 and the second magnetic suction component 11 generate magnetic attraction, repositioning the material receiving frame 5 on the fixed plate 4. Then, the lifting mechanism 6 is controlled to move the material receiving frame 5 closer to the discharge port 3 to continue the material receiving operation.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
