Description

Technical Field

[0001] The invention relates to a press-joining mechanism for a heat-insulating cover plate of a rice cooker. Background Art

[0002] At present, the design method of the heat preservation cover of the rice cooker is that the bracket and the heat preservation cover press the sealing ring, and 11 clamping feet are designed around the heat preservation cover to fix the bracket, and the 11 clamping feet are used to prevent the sealing ring, the cover and the bracket from falling off;

[0003] The original processing method is to place the cover plate assembly on the positioning tooling. The cover plate assembly includes a cover plate and a bracket. A flat-blade screw is used to manually bend the cover plate foot at 90 degrees so that the cover plate foot is clamped on the bracket groove. Because the cover plate has 11 foot clips, they need to be pressed one by one, and the assembly efficiency is low. Manual pressing can only produce about 60 cover plates per hour. Because a single cover plate has 11 buckles, manual pressing requires pressing 660 buckles per hour. The number of buckles is large and the labor intensity is high. At the same time, the strength and angle of manual hand pressing are uncontrollable, resulting in uncontrolled consistency of the 90° bending angle. If the foot clip is tilted up and not pressed into place, the entire cover plate leaks, and the rice cooker has performance problems. At the same time, some of the foot clips are bent too much due to excessive force by the operator, resulting in excessive bending angles, cracks on the bending surface, scratches on the foot clips and brackets, and the appearance is judged to be unqualified.

[0019] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] In the description of the present invention, the orientation or positional relationship indicated by terms such as "end portion" and "bottom" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0021] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "arrangement" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, which can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] As Figures 1 to 5 shown, it is a crimping mechanism for the heat preservation cover plate of a rice cooker, including a frame 1, and a positioning station 2 is arranged on the frame 1; it also includes more than three crimping mechanisms;

[0023] The crimping mechanism includes a base 3, a slide rail 4, a first driving device 6, a push block structure 7, a second driving device 8 and a pressing arm 9; the base 3 is respectively installed on the frame 1 and surrounds the positioning station 2, the first driving device 6 and the slide rail 4 are respectively installed on the base 3, and the slide rail 4 extends towards the center of the positioning station 2; the push block structure 7 includes a push block 71, the bottom of the push block 71 is matched with the slide rail 4 and can move on the slide rail 4, the driving end of the first driving device 6 drives the push block 71 to move and be positioned on the slide rail 4, the end portion of the push block 71 extends towards the center of the positioning station 2 to form two flat push rods 72, a gap 73 is left between the two flat push rods 72, and two flat push columns 74 are arranged at the end of the flat push rods 72; the second driving device 8 is installed on the push block 71, and the driving end of the second driving device 8 is connected to the pressing arm 9 to drive the pressing arm 9 to move towards the center position of the positioning station 2 and be positioned for bending the cover plate clamping feet.

[0024] During operation, in the first step, the first driving device 6 drives the push block 71 to move along the direction of the slide rail 4 towards the central position of the positioning station 2. When the movement is in place, the two flat push columns 74 abut against the sealing ring and push the sealing ring open, exposing the locking feet of the heat preservation cover plate. In the second step, the second driving device 8 pushes the pressing arm 9 to move, and the pressing arm 9 bends the locking feet of the cover plate so that the locking feet are clamped tightly in the support groove.

[0025] The pressing arms 9 of multiple crimping mechanisms simultaneously bend the locking feet of the heat preservation cover plate under the drive of the second driving device 8. The bending angles of the locking feet are consistent, which improves the working efficiency, reduces the labor intensity and the labor cost.

[0026] Two flat push columns 74 are added to the end of the flat push rod 72.
