DETAILED DESCRIPTION

[0038] In order for those skilled in the art to better understand the present application, the technical solutions of the present application are further described below in combination with the drawings and examples.

[0039] Figures 1 to 4 A metal plate turning device is shown, comprising a conveying frame 100, a turnover device for turning over plates is installed on the conveying frame 100, conveying roller sets 200 are arranged at the front and rear ends of the turnover device;

[0040] The conveying frame 100, the turnover device and the conveying roller set 200 are integrated into a modularized conveying and turnover module;

[0041] The turnover device comprises a rotating plate 300 and a turnover mechanism for driving the turnover of the rotating plate 300;

[0042] The turnover mechanism comprises a rotating shaft 403, the rotating shaft 403 is fixedly connected with rotating discs 400 at both ends, transmission shaft heads 405 are rotatably installed on the outer sides of the rotating discs 400, and the transmission shaft heads 405 are in transmission connection with first driving devices 404;

[0043] The rotating plate 300 is slidingly installed on opposite surfaces of the rotating disc 400, so that the rotating plate 300 slides downward to lower the center of gravity during the turnover of the metal plate;

[0044] The rotating plate 300 is provided with an adsorption assembly 301 for adsorbing and fixing the metal plate, the adsorption assembly 301 can be magnetic adsorption or pneumatic adsorption, and specifically can be an electromagnetic array or a pneumatic suction cup, which can be realized by using the existing technology, and the existing technology personnel should understand that it is not necessary to make more description here.

[0045] The specific way of sliding installation of the rotating plate 300 is as follows: a sliding groove 401 for matching the sliding of the rotating plate 300 is formed in the rotating disc 400, and first sliding blocks are arranged on the two sides of the rotating plate 300.

[0046] One end of the sliding groove 401 bearing the weight of the metal plate is provided with a buffer energy storage assembly 402;

[0047] The buffer energy storage assembly 402 includes a second sliding block 4021 slidingly installed along the direction of the sliding groove 401 and a first spring assembly connected thereto, which is used for buffering during the process of lowering the gravity center and pushing the metal plate forward after the turnover is completed. The buffer energy storage assembly 402 stores potential energy by using the first spring assembly during the turnover of the metal plate, and converts the potential energy into kinetic energy of the metal plate moving forward at the moment when the turnover is about to be completed, so as to push the metal plate to move forward and make it move smoothly onto the front conveying roller set 200.

[0048] The turnover plate 300 is provided with a baffle 302 near the front side, which is used for blocking the metal plate before turnover, supporting the metal plate during turnover, and providing a force point for the buffer energy storage assembly 402 to provide a reaction force when the turnover is about to be completed, playing the role of a “pushing hand”.

[0049] The position sensor 600 for detecting the position of the metal plate is arranged on the side of the rack near the baffle 302, which can be a contact sensor and a proximity sensor, but the proximity sensor is the most optimal choice. The first driving device 404 is started by automatically judging the position of the metal plate to start the turnover process.

[0050] The first spring assembly includes a spring body 4022 and a mounting seat 4023, which serves as a support for the spring body 4022 and can be fixedly installed at the end of the sliding groove 401 by a threaded fastener.

[0051] The receiving device 500 is arranged between the front conveying roller set 200, which is used for receiving and buffering the metal plate after turnover and plays a role in protecting the metal plate and the conveying roller set 200.

[0052] The receiving device 500 includes a bottom plate 501, a buffer plate 502, and a second spring assembly (not shown in the figure); the bottom plate 501 is fixed on the rack, the buffer plate 502 is located above the bottom plate 501 and is slidingly installed on the rack by cooperating with a third sliding block and a third sliding groove 503401 (opened on the conveying rack 100), and the second spring assembly is located between the bottom plate 501 and the buffer plate 502. The metal plate first falls on the buffer plate 502 after turnover, and the top side of the buffer plate 502 is provided with a buffer layer made of rubber, silicone or plastic material, which helps to play a better protection role.

[0053] The conveying roller is driven by the second driving device 201, and the first driving device 404 and the second driving device 201 can both be motors, of which the stepper motor is the most optimal choice.

[0054] In this embodiment, the control and working process of the metal plate turning device is as follows:

[0055] S1, plate feeding: the metal plate enters the turning device through the front end conveying roller group 200. During the entering process, the position sensor 600 detects the position of the plate and transmits the signal to the control system.

[0056] S2, start the turning process: when the position sensor 600 confirms that the plate has reached the predetermined position, the control system automatically starts the first driving device 404 to begin the turning operation. At this time, the adsorption assembly 301 (such as an electromagnetic array or a pneumatic suction cup) is activated to ensure that the metal plate is firmly fixed on the turning plate 300.

[0057] S3, turning operation: with the start of the first driving device 404, the rotating shaft 403 drives the two rotating discs 400 to rotate, so that the turning plate 300 installed thereon and the metal plate attached thereto begin to turn. In this process, the turning plate 300 will slide down along the sliding groove 401 on the rotating disc 400 to lower the center of gravity and reduce the kinetic and potential energy generated during turning, while the first spring assembly in the buffer energy storage assembly 402 absorbs part of the energy to play a buffering role.

[0058] S4, center of gravity adjustment and energy conversion: as the turning process proceeds, when the metal plate approaches the completion of turning, the energy stored in the buffer energy storage assembly 402 is gradually released to push the metal plate to move forward, so that it is smoothly transferred to the front conveying roller group 200. The baffle 302 plays a key role in this process, not only preventing the plate from sliding before turning, but also providing additional support during turning and providing a force point for the buffer energy storage assembly 402 to provide a reaction force when the turning is about to be completed.

[0059] S5, receiving and buffering: the turned metal plate first falls onto the receiving device 500 located between the front conveying roller group 200. The receiving device 500 includes a bottom plate 501, a buffer plate 502, and a second spring assembly, wherein the buffer layer is provided on the top side of the buffer plate 502, effectively relieving the impact when the plate falls, protecting the plate and conveying equipment.

[0060] S6, plate continues to advance: after being buffered by the receiving device 500, the metal plate is continuously transported forward by the conveying roller group 200 driven by the second driving device 201, preparing for subsequent processing or inspection operation.
