[0035] When the workpiece is heated, the workpiece is placed on the load bearing plate 4, the box door is closed, the heating device 2 is controlled to heat the inside of the box body 1, the workpiece and the elastic member 3 are heated, and the temperature at the bottom of the workpiece is higher than the temperature at the upper part of the workpiece, when the elastic member 3 reaches the deformation temperature, the elastic member 3 drives the load bearing plate 4 to move up in the box body 1 under the limitation of the light rod 5, when the load bearing plate 4 moves to the predetermined position, the positioning mechanism arranged on both sides of the box body 1 first clamps the workpiece, then the positioning mechanism arranged on the top of the box body 1 drives the load bearing plate 4 to move down, so that the load bearing plate 4 and the workpiece are separated, and then the positioning mechanism arranged on both sides of the box body 1 overturns the workpiece, and the load bearing plate 4 is reset so that the workpiece falls on the load bearing plate 4.

[0036] The application first controls the heating of the bottom of the workpiece by using the temperature at which the elastic member 3 deforms. After a period of heating, the temperature inside the box body 1 increases to make the elastic member 3 reach the deformation temperature. The elastic member 3 drives the bearing plate 4 to move upwards. Under the action of the positioning mechanism, the workpiece is turned over. Then the temperature inside the box body 1 is lowered to reset the elastic member 3, and the bearing plate 4 moves downwards, so that the other end of the workpiece can be effectively heated. Through the above arrangement, the heating efficiency of the oven of the application is much higher than that of the industrial oven on the market. At the same time, it can effectively avoid the damage of the workpiece end due to long heating time, realize the heating of different workpieces, and has wide adaptation range.

[0037] In one embodiment, the positioning mechanism includes a turnover tool arranged on both sides of the box body 1 and a limiting tool arranged on the top of the box body 1.

[0038] The turnover tool includes a support 611 and a servo motor 612 arranged thereon. The protruding shaft end of the servo motor 612 is provided with a first driving cylinder 613.

[0039] The limiting tool includes a limiting tube 621 and a second driving cylinder 622. The limiting tube 621 is installed on the light pole 5. The second driving cylinder 622 is installed on the top of the box body 1. The second driving cylinder 622 connects the limiting tube 621 through a connecting rod 623.

[0040] Referring to Figures 1 to 3 , the two turnover tools are the same structure and are arranged on both sides of the box body 1. The turnover tool includes a support 611, a servo motor 612, a first driving cylinder 613 and a clamping member 614. The limiting tool includes a limiting tube 621, a second driving cylinder 622 and a connecting rod 623. The limiting tube 621 has two, and the two limiting tubes 621 are sleeved on the two light poles 5 away from the box door. The connecting rod 623 is used to connect the two limiting tubes 621. The protruding shaft end of the second driving cylinder 622 is installed on the connecting rod 623.

[0041] When the workpiece needs to be clamped, first control the first drive cylinder 613 to drive the clamping piece 614 to move towards the workpiece to form clamping of the workpiece, then control the second drive cylinder 622 to extend the shaft to make the connecting rod 623 drive the limiting tube 621 to move downward, the lower end of the limiting tube 621 abuts on the bearing plate 4, so that the bearing plate 4 moves downward against the elastic force of the elastic element 3, so that the bearing plate 4 is separated from the workpiece, then control the servo motor 612 to drive the second drive cylinder 622 and the workpiece to rotate 180°, so that the other end of the workpiece can face downward, then control the second drive cylinder 622 to reset the limiting tube 621, under the action of the elastic element 3, the bearing plate 4 can reset upward and contact the workpiece, then control the temperature inside the box body 1 to be lower than the temperature at which the elastic element 3 deforms, so that the bearing plate 4 moves downward to approach the heating device 2, so that the workpiece can be quickly heated, effectively improving the production efficiency of the present application.

[0042] In an embodiment, the clamping piece 614 is detachably mounted on the extending shaft end of the first drive cylinder 613.

[0043] It can be understood that the clamping piece 614 can be mounted on the extending shaft end of the first drive cylinder 613 by bolts, so as to realize detachable connection of the clamping piece 614. Through this kind of setting, the type of the clamping piece 614 can be replaced according to different products, so as to meet the clamping needs of different workpieces of the present application and improve the adaptation range of the present application.

[0044] In an embodiment, the connecting rod 623 is arc-shaped curved away from the bearing plate 4.

[0045] The connecting rod 623 is arc-shaped arranged, and the connecting rod 623 is curved away from the bearing plate 4, which can increase the space for turning over the workpiece, avoid the problem that the workpiece collides with the connecting rod 623 during turning over, and improve the use effect of the present application.

[0046] In an embodiment, a limiting lug 7 is mounted on the inner wall of the box body 1, and the light rod 5 passes through the limiting lug 7, and the limiting lug 7 is located above the limiting tube 621.

[0047] Referring to Figure 3 , the limiting lug 7 is used to limit the height of upward movement of the limiting tube 621, and further limit the height of upward movement of the bearing plate 4, so as to effectively avoid the problem that the workpiece placed on the bearing plate 4 abuts on the top wall of the box body 1; it can be understood that the height of the limiting lug 7 is adjustable, so as to realize adjustable maximum upward height of the bearing plate 4, and improve the use effect of the present application.

[0048] In an embodiment, a through hole 8 is formed in the bearing plate 4, and the through hole 8 is distributed on the side of the bearing plate 4 with the central axis of the bearing plate 4 as the center.

[0049] Referring toFigure 2 By opening the through hole 8 on the bearing plate 4, the heating efficiency on the workpiece can be effectively improved.

[0050] In an embodiment, the elastic member 3 is a spring or elastic steel.

[0051] Referring to Figure 2 When the elastic member 3 is a spring, the bottom end of the elastic member 3 is installed on the bottom of the box body 1 through the rotating disc.

[0052] When the spring is deformed, the rotating disc rotates under the action of the spring, thereby offsetting the torque when the spring is deformed, reducing the damage to the spring, and improving the service life of the spring.

[0053] In an embodiment, the top surface of the bearing plate 4 is movably installed with a positioning block 9, which is used to form positioning on the workpiece.

[0054] Referring to Figure 2 A waist hole is opened on the positioning block 9, and correspondingly, a corresponding slot hole is also opened on the bearing plate 4. The positioning block 9 is installed on the bearing plate 4 through bolts, and is adjustable on the bearing plate 4 to meet the clamping and fixing of different workpieces in the present application, thereby avoiding the problem of deviation of the workpiece when moving up and down.

[0055] In an embodiment, a sleeve 11 is installed on the top of the box body 1, and the light rod 5 passes through the sleeve 11. The material of the sleeve 11 is copper or aluminum, and the part of the light rod 5 vertically moving in the sleeve 11 is provided with a rubidium magnet.

[0056] The rubidium magnet is arranged inside the light rod 5, and the sleeve 11 is long enough to keep the rubidium magnet inside the sleeve 11 at all times. The sleeve 11 is preferably made of aluminum.

[0057] When the temperature inside the box body 1 reaches the deformation temperature of the elastic member 3, the elastic member 3 drives the bearing plate 4 to move up in the box body 1, and the light rod 5 drives the rubidium magnet to move up in the sleeve 11. According to the law of Lenz, because the cross-sectional magnetic flux of the sleeve 11 below the rubidium magnet decreases in the process of the rubidium magnet rising, the cross-sectional magnetic flux of the sleeve 11 above the rubidium magnet increases. As long as the magnetic flux in the upper and lower cross sections changes, an induced current can be generated. Because the magnetic field of the induced current always hinders the change of the magnetic field of the rubidium magnet and hinders the movement of the rubidium magnet, the rubidium magnet slowly rises inside the sleeve 11, that is, the light rod 5 slowly rises in the sleeve 11, and the bearing plate 4 slowly rises in the box body 1, thereby effectively ensuring the stability of the movement of the product on the bearing plate 4, effectively avoiding the problem of the workpiece falling due to the too fast upward movement of the bearing plate 4 in the box body 1 caused by the too fast deformation speed of the elastic member 3, and effectively improving the heating efficiency on the workpiece.

[0058] Correspondingly, when the bearing plate 4 moves downward in the box 1, that is, the rubidium magnet moves downward in the copper sleeve 11, according to the Lenz law, the rubidium magnet can move slowly in the sleeve 11, so as to ensure the stability of the movement of the bearing plate 4.

[0059] It can be understood that the movement speed of the rubidium magnet in the copper sleeve 11 is higher than that in the aluminum sleeve 11, and by selecting the sleeve 11 made of different materials, the movement speed of the bearing plate 4 can be controlled, and the selection of the material of the sleeve 11 is not limited.

[0060] In an embodiment, the material of the bearing plate 4 is copper or aluminum. By this arrangement, the rapid heating of the bearing plate 4 can be realized, and the baking and drying efficiency of the workpiece is improved.

[0061] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable the person skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
