Description

Technical Field

[0001] The present application relates to the field of detection devices, and in particular to a spring-loaded plate detection mechanism. Background Art

[0002] A spring is a mechanical component that works by using elasticity. After being deformed by an external force, it can return to its original shape by its own elasticity when the external force disappears. The application of springs is extremely wide. The spring can be connected between two workpieces to make a spring carrier 100. Figure 1 The spring carrier plate 100 includes a first carrier plate 110, a second carrier plate 130 and a plurality of springs 120. The springs 120 are located between the first carrier plate 110 and the second carrier plate 130. The first carrier plate 110, the second carrier plate 130 and the springs 120 are fixed together by riveting.

[0003] In order to ensure the quality and performance of the spring carrier 100, it is usually necessary to test the strength of the spring 120, whether the spring 120 is missing, whether the spring 120 is not riveted into place, and whether the left-right spiral spring 120 is installed incorrectly.

[0004] Most of the existing inspection methods rely on manual operation. The staff manually puts the spring carrier 100 on the inspection device for inspection. Whether the spring 120 is missing, whether the spring 120 is riveted in place, and whether the left-right spiral spring 120 is installed incorrectly are inspected by the staff's naked eye. This is not only inefficient, but also easily affected by human factors, resulting in unstable inspection results, causing defective products in the final product, and reducing the overall quality of the product.

DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0036] The embodiment of the present application discloses a spring load plate detection mechanism.

[0037] Reference Figure 2 and Figure 3 A spring carrier plate detection mechanism includes an optical detection device 1, a mechanical detection device 2, a recovery box 3, a manipulator 4 and a feeding mechanism 5. The optical detection device 1 is used to detect the assembly status of the spring carrier plate 100, the mechanical detection device 2 is used to detect the strength of the spring in the spring carrier plate 100, and the manipulator 4 is used to grab and move the spring carrier plate 100. The optical detection device 1, the mechanical detection device 2, the recovery box 3 and the feeding mechanism 5 surround the manipulator 4 to facilitate the operation of the manipulator 4. A feeding device 6 is also provided on the side of the recovery box 3 away from the manipulator 4, which is used to feed the spring carrier plate 100 to be detected into the system.

[0038] The robot 4 grabs the spring carrier 100 transported from the previous process through the feeding device 6, and then places the spring carrier 100 on the optical detection device 1 for detection. If the detection fails, the robot 4 places the spring carrier 100 in the recycling box 3. If the detection passes, the robot 4 places the spring carrier 100 on the mechanical detection device 2 for detection. If the mechanical detection device 2 fails the detection, the robot 4 places the spring carrier 100 in the recycling box 3. If the detection passes, the robot 4 places the spring carrier 100 on the unloading mechanism 5 and sends it to the next process, and the above operations are repeated in sequence.

[0039] Reference Figure 3 and Figure 4 Specifically, the optical inspection device 1 includes a visual camera 11, a mounting platform 12, a testing platform 13 and a motor 14. The visual camera 11 is fixed to the upper end surface of the mounting platform 12, and is used to detect the spring carrier 100 on the testing platform 13. The lens of the visual camera 11 is arranged above the testing platform 13 and is directly opposite to the axis of the rotating shaft of the motor 14 in the horizontal direction to judge whether the spring is missing, whether the spring is riveted in place, and whether the left and right spiral springs are installed incorrectly. The testing platform 13 is located above the mounting platform 12 and is fixedly connected to the rotating shaft of the motor 14, so that the motor 14 can drive the testing platform 13 to rotate, so that the visual camera 11 can fully capture the assembly of the spring carrier 100 on the testing platform 13. In order to improve the stability of the rotation of the testing platform 13, a support seat 121 is also provided on the mounting platform 12, and the testing platform 13 is located on the upper end surface of this support seat 121. The rotating shaft of the motor 14 passes through the support seat 121 and is rotatably connected to the support seat 121. Such a design further enhances the stability of the testing platform 13 when rotating.

[0040] Reference Figure 4 and Figure 5 , a plurality of balls 122 are arranged on the upper end surface of the support seat 121, and the balls 122 are rotatably connected to the support seat 121, and the lower end surface of the detection platform 13 abuts against the balls 122. Such a design converts the sliding friction between the detection platform 13 and the support seat 121 into rolling friction, thereby reducing the resistance of the detection platform 13 when rotating, and making the detection platform 13 rotate more smoothly.

[0041] Reference Figure 3 and Figure 6 The mechanical detection device 2 includes a workbench 21, a sensor 22, a lifting plate 23, an upper pressure plate 24 and a lower pressure plate 25. A through slot 211 is provided on the side of the workbench 21 close to the manipulator 4, and the lifting plate 23 is slidably connected with the workbench 21 in the vertical direction in the through slot 211. A hydraulic cylinder 212 is installed on the upper end surface of the through slot 211, and the output end of the hydraulic cylinder 212 is fixedly connected to the lifting plate 23, so as to drive the lifting plate 23 to move up and down in the through slot 211.

[0042] Reference Figure 6 The sensor 22 is mounted on the lower end surface of the lifting plate 23 to detect pressure changes. The upper pressure plate 24 is located at the lower end surface of the sensor 22 and moves together with the sensor 22. The lower pressure plate 25 is fixed on the lower end surface of the through groove 211 to cooperate with the upper pressure plate 24 to clamp and detect the strength of the spring in the spring carrier 100.

[0043] Reference Figure 3 and Figure 6 In order to facilitate the manipulator 4 to take and place the spring carrier 100, a cylinder 213 is further provided on the lower end surface of the through slot 211. The output end of the cylinder 213 is fixedly connected to the side of the lower pressure plate 25 away from the manipulator 4, so that the lower pressure plate 25 can be slidably connected to the workbench 21 along the through direction of the through slot 211. Under the push of the cylinder 213, the lower pressure plate 25 can be moved out of the through slot 211 to provide space for the operation of the manipulator 4.

[0044] Reference Figure 3 and Figure 6 In order to improve the stability of the movement of the lower platen 25, a slide rail 214 is further provided on the lower end surface of the through slot 211, and a slider 251 adapted to the guide rail is provided on the lower end surface of the lower platen 25. One end of the slide rail 214 extends out of the through slot 211 and extends in the direction in which the output end of the cylinder 213 extends, so that during the movement of the lower platen 25, the slider 251 always slides on the slide rail 214, ensuring the stability and accuracy of the movement of the lower platen 25.

[0045] Reference Figure 3 and Figure 7 The lower end surface of the recycling box 3 is provided with a plurality of moving wheels 31, which facilitates the movement and transportation of the recycling box 3. The recycling box 3 is close to the feeding device 6 for conveying the spring carrier 100 to be inspected, so that the manipulator 4 can quickly grab another spring carrier 100 from the feeding device 6 after putting the unqualified spring carrier 100 into the recycling box 3.

[0046] The implementation principle of a spring carrier plate detection mechanism in the embodiment of the present application is as follows: the manipulator 4 grabs the spring carrier plate 100 transported from the previous process through the feeding device 6, and then places the spring carrier plate 100 on the optical detection device 1 for detection. If the detection fails, the manipulator 4 places the spring carrier plate 100 in the recycling box 3. If the detection passes, the manipulator 4 places the spring carrier plate 100 on the mechanical detection device 2 for detection; after the mechanical detection device 2 fails the detection, the manipulator 4 places the spring carrier plate 100 in the recycling box 3. After the detection passes, the manipulator 4 places the spring carrier plate 100 on the unloading mechanism 5. The above actions are repeated cyclically to detect the quality of the spring carrier plate 100, and automation is achieved. The optical detection device 1 is used to detect the assembly status of the spring carrier plate 100, without manual detection, which improves the detection efficiency and accuracy. The automated operation of the manipulator 4 reduces manual intervention, further improves the automation level of the detection process, improves the detection efficiency and accuracy, and improves product quality.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
