Description

Technical Field

[0001] This invention relates to the field of electric rice cooker manufacturing equipment technology, and in particular to an automatic pressing and bending device and method for lid clamps. Background Technology

[0002] An electric rice cooker, also known as a rice pot, is a very common cooking appliance in daily life, saving manpower and energy. An electric rice cooker typically consists of a pot body and a keep-warm lid mounted on the pot body. The keep-warm lid includes a lid assembly, which usually includes a support frame, a lid fixed to the support frame, and a sealing ring. The lid is secured to the support frame by multiple clips, and the sealing ring covers the clips. During manufacturing, the multiple clips are pressed together to secure the lid and support, preventing the lid from becoming detached.

[0003] The existing assembly process for the cover plate and bracket is as follows: the bracket and cover plate are placed on a positioning fixture, and workers use tools to bend the cover plate's clamping feet, causing the clamping feet to lock into the bracket's grooves. This production method is inefficient and cannot guarantee production quality. It is easy for the bending angle of the clamping feet to be too large or too small, ultimately resulting in substandard quality insulation covers and reduced enterprise profits.

[0004] Therefore, improving the assembly efficiency of the cover plate and the bracket and ensuring the assembly quality are of great significance to rice cooker manufacturers. Summary of the Invention

[0041] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0042] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0043] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] like Figures 1-8 As shown, the present invention provides an automatic pressing and bending device for cover plate clamps. The device includes a main body 1, on which a pressing mechanism 200 and a placement position 100 for placing cover plates and supports are provided. The pressing mechanism 200 includes a first bending device 210 and a second bending device 220.

[0045] The cover plate is provided with a locking foot. The first bending device 210 is used to bend the locking foot once, and the second bending device 220 is used to bend the locking foot a second time. After the first bending and the second bending, the locking foot is fastened to the bracket.

[0046] Specifically, the first bending device 210 is disposed around the placement position 100, and the bending is a horizontal bending of the clamp foot.

[0047] The second bending device 220 is disposed on the first bending device 210, and the secondary bending is a vertical bending of the clamp foot.

[0048] In practical applications, the cover plate is provided with multiple locking feet, and each locking foot needs to be pressed and bent.

[0049] Therefore, multiple first bending devices 210 and second bending devices 220 need to be set up to ensure that each clamping foot has one corresponding first bending device 210 and one second bending device 220. During the clamping foot pressing and bending operation, each of the first bending devices 210 and the second bending device 220 is activated simultaneously to press and bend multiple clamping feet at the same time, so that each clamping foot is fastened to the bracket at the same time, which can improve production efficiency and ensure production quality.

[0050] In a more specific embodiment, eight clamping feet are provided on the cover plate, and both the first bending device 210 and the second bending device 220 are provided with eight feet each, so as to simultaneously press and bend each clamping foot. In a more specific embodiment, after the cover plate and the bracket are placed on the placement position 100, they need to be fixed. This application also claims protection for a placement position 100 for a cover plate and a bracket. Specifically: the placement position 100 includes a contour plate 110 and a clamping cylinder 120. The contour plate 110 is fixed on the main body 1, and the clamping cylinder 120 is disposed around the contour plate 110. The contour plate 110 is used to place the cover plate and the bracket, and the clamping cylinder 120 is used to press the cover plate and the bracket onto the contour plate 110.

[0051] The shapes of the cover plate and the bracket are adapted to the shape of the contour plate 110, so that the cover plate and the bracket can be effectively fixed on the contour plate 110. The piston rod axis of the clamping cylinder 120 is vertical. When the piston rod of the clamping cylinder 120 extends, the operator places the cover plate and the bracket on the contour plate 110. Then the piston rod of the clamping cylinder 120 retracts. A pressure plate can be provided on the piston rod of the clamping cylinder 120 to clamp the cover plate and the bracket. It should be noted that this application can also be configured with an automatic feeding robot to realize the loading and unloading of the cover plate and the bracket.

[0052] The aforementioned automatic pressing and bending device for cover plate feet includes a pressing mechanism 200 and a placement position 100 for placing the cover plate and the bracket on the main body 1. The pressing mechanism 200 includes a first bending device 210 and a second bending device 220. The cover plate has feet. In use, after the cover plate and the bracket are placed on the placement position 100 and fixed, the first bending device 210 is activated to bend the feet once. After the first bend, the feet are fastened to the bracket, but the cover plate and the bracket are not completely fixed. After the first bend, the second bending device 220 is activated to bend the feet a second time. After the second bend, the feet are fully fastened to the bracket, and the cover plate and the bracket are completely fixed, thus completing the assembly of the cover plate and the bracket. This device requires no manual operation during the pressing and bending process of the feet, resulting in a high degree of automation and high production efficiency. Moreover, the bending force of the feet is controllable, ensuring the assembly quality of the cover plate and the bracket.

[0053] In one specific embodiment, the first bending device 210 includes a first driving device 2101 and a first pressing block 2102. The first driving device 2101 is disposed around the placement position 100, and the first pressing block 2102 is fixed to the output end of the first driving device 2101. The first driving device 2101 drives the first pressing block 2102 to move in the horizontal direction, so that the first pressing block 2102 moves away from or closer to the center of the placement position 100.

[0054] The first driving device 2101 can be a cylinder or a push rod motor. The first driving device 2101 includes a piston rod, and the horizontal movement of the first pressure block 2102 is achieved by driving the extension and retraction of the piston rod. It should be noted that the axis of the piston rod of the first driving device 2101 is parallel to the horizontal plane.

[0055] Furthermore, the second bending device 220 includes a second driving device 2201 and a second pressing block 2202. The second driving device 2201 is fixed on the first pressing block 2102, and the second pressing block 2202 is disposed at the output end of the second driving device 2201. The second driving device 2201 drives the second pressing block 2202 to move in the vertical direction, so that the second pressing block 2202 moves closer to or further away from the placement position 100.

[0056] It should be noted that after the second driving device 2201 is fixed on the first pressing block 2102, the second pressing block 2202 should not interfere with the first pressing block 2102 when it is driven by the second driving device 2201. In one specific embodiment, the first driving device 2101 is located at the outer edge of the placement position 100. When the cover plate and the bracket are placed on the placement position 100, the first pressing block 2102 corresponds to the locking foot but does not contact it. The second pressing block 2202 is located above the locking foot of the cover plate. When pressing is required, the first driving device 2101 is activated, pushing the first pressing block 2102 to bend the locking foot, so that the locking foot is bent from a horizontal position into an "L" shape. After the first pressing block 2102 is bent, the second driving device 2201 drives the second pressing block 2202 to bend the locking foot a second time, so that the "L"-shaped locking foot is completely fastened to the bracket. Since a cover plate has multiple clamping feet, multiple first bending devices 210 are provided around the placement position 100, and each first bending device 210 is provided with a second bending device 220.

[0057] Furthermore, a clamping device 400 is provided above the placement position 100;

[0058] The cover plate is provided with a sealing ring, which covers the locking foot;

[0059] The clamping device 400 is used to clamp the sealing ring before bending the clamp foot and expose the clamp foot; after the clamp foot is exposed outside the sealing ring, the first bending device 210 and the second bending device 220 perform the clamp foot bending operation.

[0060] The keep-warm lid of a rice cooker serves two purposes: improving the sealing performance and enhancing its aesthetics. However, during the assembly of the lid and the support, the sealing ring must be clamped up first, exposing the retaining feet, before the retaining feet can be pressed and bent. Therefore, this application includes a clamping device 400 to clamp the sealing ring, facilitating the operation of the first bending device 210 and the second bending device 220.

[0061] More specifically, a support frame 300 is provided above the placement position 100, and the clamping device 400 is provided on the support frame 300; the support frame 300 includes a support rod 310, a fixed plate 330, and a movable plate 320; the support rod 310 is vertically arranged on the main body 1, the fixed plate 330 is fixed to the top of the support rod 310, and the movable plate 320 is movably arranged on the support rod 310; a lifting drive device 340 is provided on the fixed plate 330, the output end of the lifting drive device 340 is fixedly connected to the movable plate 320, the lifting drive device 340 drives the movable plate 320 to move up and down on the support rod 310, and the clamping device 400 is provided on the movable plate 320.

[0062] Four support rods 310 are provided on the main body 1, and the fixing plate 330 is fixed to the top of the four support rods 310. The movable plate 320 is connected to the support rods 310 through a linear bearing, so that the lifting drive device 340 can drive the movable plate 320 to move up and down on the support rods 310. The up-and-down movement of the movable plate 320 can change the distance between the clamping device 400 and the placement position 100.

[0063] Furthermore, the clamping device 400 includes a rotary cylinder 410, a cam turntable 420, a guide plate 430, and a pneumatic gripper 440. The rotary cylinder 410 and the guide plate 430 are both fixed on the movable plate 320. The cam turntable 420 is disposed between the rotary cylinder 410 and the guide plate 430. The pneumatic gripper 440 is disposed below the guide plate 430 and connected to the cam turntable 420. The rotary cylinder 410 drives the cam turntable 420, and rotating the cam turntable 420 causes the pneumatic gripper 440 to move radially along the guide plate 430.

[0064] In a more specific embodiment, the cam turntable 420 is provided with a guide rod 4201, and the guide disk 430 is provided with a guide groove 4301. The guide rod 4201 passes through the guide groove 4301 and is fixedly connected to the pneumatic gripper 440. When the rotary cylinder 410 drives the cam turntable 420 to rotate, the cam turntable 420 drives the guide rod 4201 to move radially along the guide disk 430.

[0065] Both the rotary cylinder 410 and the cam turntable 420 are bolted to the movable plate 320. The guide plate 430 and the cam turntable 420 are both cylindrical structures. Multiple pneumatic grippers 440 are provided. More specifically, the number of pneumatic grippers 440 is the same as the number of clamping feet on the cover plate. The working process of the clamping device 400 is as follows: When the cover plate and the bracket are placed on the placement position 100, the sealing ring on the cover plate covers the clamping feet, thus preventing bending operations. At this time, the lifting drive device 340 drives the movable plate 320 to move from top to bottom above the placement position 100, causing the clamping device 400 to approach the placement position 100. After the clamping device 400 moves into position, the rotary cylinder 410 is activated, driving the cam turntable 420 to rotate, causing each of the pneumatic grippers 440 to extend. After the pneumatic grippers 440 extend into position, they clamp the sealing ring. Then the rotary cylinder 410 rotates in the opposite direction, causing the pneumatic gripper 440 to retract inward, exposing the clamping feet. After the clamping feet are exposed, each bending device can perform bending operations.

[0066] More specifically, the pneumatic gripper 440 includes a fixing module 4401, a gripper cylinder 4402, and a pneumatic clamp 4403. The fixing module 4401 is fixedly connected to the guide rod 4201. The gripper cylinder 4402 is fixed to the fixing module 4401. The pneumatic clamp 4403 is connected to the gripper cylinder 4402 and is driven by the gripper cylinder 4402. The fixing module 4401 may be a plate-like structure and is fixedly connected to the guide rod 4201 by bolts. The pneumatic clamp 4403 is mounted on the gripper cylinder 4402.

[0067] In a preferred embodiment, a damping buffer 500 is provided around the placement position 100. The damping buffer 500 is disposed on the main body 1 and corresponds to the movable plate 320. The buffer damper has a built-in compression spring, which limits the movement of the movable plate 320. It can provide resistance to the movable plate 320 when the movable mounting plate is pressed down, preventing the movable plate 320 from colliding with the main body 1 and damaging the parts. The damping buffer 500 has a fixed stroke. When the movable plate 320 is pressed down to the minimum stroke of the damping buffer 500, it is the working position that the movable plate 320 needs to reach. At this time, the damping buffer 500 has reached the minimum stroke and cannot be compressed further, thus limiting the movement of the movable plate 320.

[0068] like Figure 9 As shown, the present invention also provides an automatic pressing and bending method for cover plate clamps based on the above-mentioned automatic pressing and bending device for cover plate clamps, the method comprising the following steps:

[0069] S100. Place the cover plate and bracket on the placement position 100, and expose the clips on the cover plate.

[0070] S200, Bend the clamping foot once so that the clamping foot is bent in the horizontal direction;

[0071] S300. The clamping foot that is bent in the horizontal direction is bent again, so that the clamping foot is bent again in the vertical direction, and the bent clamping foot is fastened to the bracket.

[0072] This method has high efficiency in pressing and bending the clamps, and can ensure the pressing and bending quality of the clamps, thereby improving the assembly efficiency of the cover plate and the bracket and ensuring production quality.
