Description

Technical Field

[0001] The utility model relates to the technical field of spray fixing devices, in particular to an inner pot fixing device and an inner pot spraying device formed by the inner pot fixing device. Background Art

[0002] When spraying the inner pot of an electric rice cooker, the inner pot needs to be fixed on the side of the spraying device and kept rotating during the spraying process so that the inner wall of the inner pot is evenly sprayed. In the prior art, in order to achieve the fixation and rotation of the inner pot, a rotating column is set on the side of the spraying production line, a suction cup is set above the rotating column, and a manipulator grabs the inner pot and places it on the rotating column. The bottom of the inner pot is fixed on the rotating column through the suction cup. During the spraying process, the rotating column drives the inner pot to rotate to achieve even spraying of the inner wall of the inner pot.

[0003] The existing spray fixing device has the following defects: after the robot arm clamps the inner pot, it cannot be accurately placed in the center position of the automatic spray rotating column, so that the suction cup on the rotating column can only suck the bottom of the inner pot off-center. During the spraying process, the inner pot is affected by the rotating centrifugal force, and there is serious shaking, which affects the consistency of the spraying thickness. For products with heavier inner pots, there is a problem of directly throwing them out, which seriously affects the spraying quality and the first-time pass rate of the inner pot. Utility Model Content

[0004] In order to overcome the problems existing in the related technology, one of the purposes of the utility model is to provide an inner pot fixing device, wherein the adsorption component in the fixed base is used to adsorb the bottom of the inner pot, and the side plate is used to limit the inner pot to ensure that the inner pot is placed in the center position of the fixed base to avoid deviation of the center of the inner pot.

[0005] An inner pot fixing device is connected to a rotating drive component, characterized in that it includes a fixed base and a side plate, wherein the fixed base and the side plate surround a placement position for the inner pot; an adsorption component is arranged in the fixed base, and the side plates are evenly distributed on the edge of the fixed base; and the device is used to limit the side wall of the inner pot.

[0006] The present application can fix the outer side of the inner pot and ensure that the center of the inner pot coincides with the center of the fixed base through the cooperation of the side panels and the adsorption assembly; at the same time, the inner pot fixing device is connected to the rotating drive member, and when the rotating drive member drives the inner pot fixing device to rotate, the inner pot, the fixed base and the side panels keep rotating synchronously. Since the centers of the inner pot and the fixed base coincide, the shaking and being thrown out problems caused by the deviation of the center of the inner pot in the prior art are avoided.

[0007] In a preferred technical solution of the utility model, the fixed base is circular, and an adsorption component is arranged in the central area of ​​the fixed base.

[0008] When the fixed base is a circular structure, the magnet can be a cylindrical structure and installed at the center of the fixed base. The reason for installing it at the center is to fix the central area of ​​the inner pot. When the inner pot is rotating and spraying, each position in the central area is evenly adsorbed, which can ensure that the axis line of the inner pot always coincides with the axis line of the fixed base during rotation.

[0009] In a preferred technical solution of the present utility model, a gasket is provided in the edge area of ​​the fixed base.

[0010] The gasket can be made of flexible material. When the inner pot is placed on the placement position, the inner pot is moved to the top of the placement position under the clamping action of the robot. When the inner pot contacts the side panel, the robot can release the clamping. At this time, the inner pot will fall under the action of gravity. The gasket can provide a buffering protection for the inner pot to prevent the inner pot from colliding with the fixed base when falling and causing scratches.

[0011] In a preferred technical solution of the present invention, there are M side panels, and the M side panels are symmetrically arranged relative to the center of the fixed base, and M is an even number greater than 0.

[0012] When the fixed base and the bottom of the inner pot are both circular, an even number of side panels are symmetrically distributed with the center of the fixed base as the center point; the reason for setting up multiple symmetrical side panels is that if the axis line of the inner pot deviates from the axis line of the fixed base during rotation, the inner pot will be affected by centrifugal force. At this time, symmetrical side panels are needed to fix the inner pot to prevent it from shaking.

[0013] In a preferred technical solution of the present utility model, the side plate is located in a slide groove, and the slide groove extends toward the center of the fixed base.

[0014] In the present application, the positions of the side panels and the center of the fixed base can be relatively changed. The side panels are located in the chute and can slide along the chute. The position of the side panels in the chute needs to be determined according to the outer diameter of the inner pot. After the outer diameter of the inner pot is determined, the position of the side panels in the chute is moved so that the distance between the side panels and the center point of the fixed base is equal to the outer diameter of the inner pot. The extension direction of the chute is from the edge of the fixed base to the center of the fixed base. For example, when the fixed base is circular, the extension direction of the chute is the radius direction of the circular fixed base. When the position of the side panels needs to be adjusted, the positions of all the side panels in the chute need to be adjusted at the same time to ensure that the distances of all the chutes from the center point of the fixed base are adapted to the size of the inner pot. The present application sets the side panels to be slidable, which can expand the application range of the fixing device. When the sizes of the inner pots to be fixed are different, the side panels only need to be moved along the chute to adapt to inner pots of different sizes. Once the size of the inner pot is determined and the position of the side panel in the slide slot is determined, the side panel can be fixed in the slide slot by tightening screws to ensure that the position of the side panel remains fixed relative to the slide slot while the inner pot of the corresponding size is being fixed.

[0015] In a preferred technical solution of the utility model, a mounting plate is provided on the edge of the fixed base, and the sliding groove is located in the mounting plate.

[0016] When the fixed base is a circular structure, the mounting plates are symmetrically arranged at the edge of the fixed base, and the mounting plates can be rectangular plate-like structures, and the adjacent fixed bases are fixed at the edge of the fixed base at 90°. The side of the mounting plate away from the fixed base can be set to an arc structure to prevent the edge of the mounting plate from being too sharp and causing damage to the staff or devices outside the fixing device. In the present application, the mounting plate and the fixed base can be an integrally formed structure. Among them, the number of mounting plates corresponds to the number of side plates one by one, which can be four, six or eight, and the multiple mounting plates are evenly distributed on the outer peripheral side of the fixed base. At the same time, the multiple mounting plates are symmetrically centered with the center point of the fixed base.

[0017] In a preferred technical solution of the utility model, the slide groove is provided with scale lines extending along a first direction, and the first direction is parallel to the extension direction of the slide groove.

[0018] When the fixed base is a circular structure, the extension direction of the chute is the radius direction of the circular fixed base, and the first direction is also the radius direction of the circular fixed base. The extension direction of the scale line itself is perpendicular to the first direction, and a fixed distance is maintained between adjacent scale lines. The scale lines can be used to indicate the distance between the current position and the center of the fixed base. When the side panel slides in the chute, you only need to see which scale line position the side panel slides to to determine the distance between the side panel and the center of the fixed base. The present application sets scale lines in each chute at the same time. By moving the side panel to a fixed scale line position, it can ensure that the distances of multiple chutes from the center of the fixed base are the same. There is no need to measure the side panel position when moving the side panel position. The scale lines can ensure that the position of the side panel is adapted to the size of the inner pot, thereby improving the efficiency of the side panel adjustment.

[0019] In a preferred technical solution of the utility model, the adsorption component is a magnet.

[0020] Correspondingly, the bottom of the inner pot is made of iron. When the inner pot is placed in the placement position, the magnet can adsorb the bottom of the inner pot, so that the position of the inner pot is uniquely fixed. The use of magnets as adsorption components has a simple structure and occupies a small area, which can ensure that the fixing device can effectively fix the inner pot.

[0021] In a preferred technical solution of the present invention, the side of the side panel close to the center of the fixed base includes a first end face and a second end face, the first end face is arranged perpendicular to the fixed base, and the first end face is located at the bottom of the side panel, the second end face is an arc-shaped structure, and the second end face extends from the top of the first end face toward a direction away from the center point of the fixed base.

[0022] In the present application, the side panels are fixed on the upper surface of the fixed base, and the bottom of the side panels refers to the side close to the fixed base in the vertical direction. The first end face is a vertical end face, which is used to abut and fix the outer wall of the inner pot, and the second end face is an arc-shaped structure, and the second end face is covered with a flexible material, such as a protective layer such as high-quality flannel. When the inner pot is placed above the placement position, the position of the inner pot is not uniquely determined. Since the arc-shaped structure expands outward, the area above the placement position is larger than the bottom cross-sectional area of ​​the inner pot. At this time, whether the inner pot is held by hand or clamped by a robotic arm, it can be adjusted and moved in the space surrounded by the arc-shaped structure. When the inner pot contacts the second end face on one of the side panels, the robotic arm releases the inner pot. At this time, under the action of gravity, the inner pot descends. During the descent, the arc-shaped second end face can adjust the position of the inner pot, so that when the bottom of the inner pot abuts against the fixed base, the axis of the inner pot coincides with the axis of the fixed base, and the position of the inner pot is uniquely fixed. The arc-shaped second end surface of the present application can facilitate the inner pot to slide into the placement position, and after being covered with the protective layer, it can prevent the outer wall of the inner pot from being scratched, thereby protecting the outer wall of the inner pot.

[0023] The second purpose of the utility model is to provide an inner pot spraying device, including the inner pot fixing device as described above.

[0024] When the bottom of the inner pot abuts against the fixed base, the adsorption assembly adsorbs and fixes the bottom of the inner pot to ensure that the center of the inner pot coincides with the center of the fixed base; the rotating drive drives the fixed base, side panels and inner pot to rotate simultaneously to achieve uniform spraying of the inner wall of the inner pot, thereby improving the spraying efficiency and uniformity.

[0025] The beneficial effects of the utility model are:

[0026] The utility model provides an inner pot fixing device, comprising a fixing base and side panels, wherein the fixing base and the side panels surround a placement position of the inner pot; an adsorption component is arranged in the fixing base, and the side panels are evenly distributed on the edge of the fixing base; and the device is used for limiting the side wall of the inner pot. When the robot grabs the inner pot and places it on the placement position, since the side panels are evenly distributed at the edge of the fixed base, the side panels can limit the position of the inner pot. Even if the robot is offset when placing the inner pot, under the action of the side panels, the inner pot can automatically adjust its position when contacting the fixed base, so that the center of the inner pot coincides with the center of the fixed base; when the bottom of the inner pot abuts against the fixed base, the adsorption component adsorbs and fixes the bottom of the inner pot to ensure that the position of the inner pot is fixed. The present application can fix the outer side of the inner pot and ensure that the center of the inner pot coincides with the center of the fixed base through the cooperation of the side panels and the adsorption component; at the same time, the inner pot fixing device is connected to the rotating drive member. When the rotating drive member drives the inner pot fixing device to rotate, the inner pot, the fixed base and the side panels keep rotating synchronously. Since the centers of the inner pot and the fixed base coincide, the shaking and throwing out problems caused by the deviation of the center of the inner pot in the prior art are avoided.

[0027] The present application also provides an inner pot spraying device, comprising the inner pot fixing device as described above, wherein, when the bottom of the inner pot abuts against the fixed base, the adsorption assembly adsorbs and fixes the bottom of the inner pot to ensure that the center of the inner pot coincides with the center of the fixed base; the rotating drive member drives the fixed base, side plate and inner pot to rotate simultaneously to achieve uniform spraying of the inner wall of the inner pot, thereby improving the spraying efficiency and uniformity.

[0041] Example 1

[0042] like Figure 1-Figure 8 As shown, an inner pot fixing device is connected to a rotating drive member, specifically comprising a fixed base 11 and a side plate 21, wherein the fixed base 11 and the side plate 21 surround a placement position for the inner pot; an adsorption component is arranged in the fixed base 11, and the side plate 21 is evenly distributed on the edge of the fixed base 11; and is used to limit the side wall of the inner pot.

[0043] In the present application, the rotary drive member is used to drive the entire fixing device to rotate. Specifically, the rotary drive member is connected to the bottom of the fixing base 11, and the side plate 21 is arranged above the fixing base 11. The rotary drive member drives the fixing base 11 to rotate around its axis, and the side plate 21 and the fixing base 11 are fixed together; when the inner pot is placed in the placement position, the side plate 21 and the adsorption assembly fix the inner pot to ensure that the inner pot and the fixing base 11 keep rotating synchronously.

[0044] In the present application, the inner pot refers to the inner pot of an electric rice cooker or the inner pot of a pressure cooker.

[0045] In the present application, the rotating driving member can be a driving structure such as a motor, and the output end of the motor is connected to the axis centerline position of the fixed base 11. When the motor runs, it drives the fixed base 11 to rotate around its axis centerline.

[0046] The present application can place the inner pot in the placement position manually or by using a robot gripper; when placed manually, it is only necessary to place the inner pot in the area between the side panels 21. Under the action of gravity, the inner pot descends and automatically adjusts its position so that the outer side of the inner pot abuts against the multiple side panels 21. When the bottom of the inner pot abuts against the fixed base 11, the adsorption component in the fixed base 11 adsorbs the inner pot. In this way, the adsorption component is used to adsorb and fix the bottom of the inner pot, and there are multiple side panels 21, which are used to fix the outer side wall of the inner pot from different positions.

[0047] The present application can ensure that when the inner pot is placed in the fixed base 11, the axis of the inner pot coincides with the axis of the fixed base 11 by symmetrically setting the position of the side plate 21. When the rotating drive member drives the fixed base 11 to rotate, the outer wall of the inner pot is limited by the side plate 21 and will not be offset. This avoids the inner pot shaking or being thrown out due to the axis offset between the inner pot and the fixed base 11 in the prior art.

[0048] When the manipulator grabs the inner pot and places it on the placement position, since the side panels 21 are evenly distributed at the edge of the fixed base 11, the side panels 21 can limit the position of the inner pot. Even if the manipulator is offset when placing the inner pot, under the action of the side panels 21, the inner pot can automatically adjust its position when it contacts the fixed base 11, so that the center of the inner pot coincides with the center of the fixed base 11; when the bottom of the inner pot abuts against the fixed base 11, the adsorption component adsorbs and fixes the bottom of the inner pot to ensure that the position of the inner pot is fixed. The present application can fix the outer side of the inner pot and ensure that the center of the inner pot coincides with the center of the fixed base 11 through the cooperation of the side panels 21 and the adsorption component; at the same time, the inner pot fixing device is connected to the rotating drive member. When the rotating drive member drives the inner pot fixing device to rotate, the inner pot, the fixed base 11 and the side panels 21 rotate synchronously. Since the centers of the inner pot and the fixed base 11 coincide, the shaking and being thrown out problems caused by the deviation of the center of the inner pot in the prior art are avoided.

[0049] Example 2

[0050] like Figure 1-Figure 8 As shown, an inner pot fixing device is connected to a rotating drive member, specifically comprising a fixed base 11 and a side plate 21, wherein the fixed base 11 and the side plate 21 surround a placement position for the inner pot; an adsorption component is arranged in the fixed base 11, and the side plate 21 is evenly distributed on the edge of the fixed base 11; and is used to limit the side wall of the inner pot.

[0051] The bottom of the inner pot in the present application is circular, so the placement position also corresponds to a circular structure. The placement position in the present application is adapted to the shape of the inner pot. The side panel 21 in the present application can be one side panel 21 distributed along the edge of the fixed base, or it can be multiple side panels 21, and the multiple side panels 21 are evenly distributed at the edge of the fixed base 11.

[0052] Specifically, when the side panel 21 is an integral part, the side panel 21 is an annular structure, extending along the edge of the fixed base 11. When the inner pot is placed in the fixed base 11, ensure that the side panel 21 just surrounds the outer peripheral side of the inner pot and abuts against the outer wall of the inner pot.

[0053] In actual operation, the side plate 21 can be a complete annular structure or a partial annular structure with an extension length greater than a semicircle, and it is only necessary to ensure that the side plate 21 can limit the position of the inner pot. In particular, when the rotating drive member drives the inner pot and the fixed base 11 to rotate, the side plate 21 needs to ensure that the axis of the inner pot always coincides with the axis of the fixed base 11 to avoid the inner pot position shifting, causing the inner pot to shake or be thrown out during rotation.

[0054] Specifically, when there are multiple side panels 21 , M side panels 21 are provided, and the M side panels 21 are symmetrically arranged relative to the center of the fixed base 11 , and M is an even number greater than 0.

[0055] When the fixed base 11 and the bottom of the inner pot are both circular, an even number of side panels 21 are symmetrically distributed with the center of the fixed base 11 as the center point; the reason for setting multiple side panels 21 to be symmetrically distributed is that if the axis line of the inner pot deviates from the axis line of the fixed base 11 during the rotation process, the inner pot will be affected by centrifugal force. At this time, the side panels 21 that are symmetrically arranged need to fix the inner pot to prevent it from shaking.

[0056] The shape of the placement position in the present application can be adapted to the shape of the inner pot. When the inner pot is cylindrical, the placement position surrounded by the fixed base 11 and the side plate 21 is a cylindrical structure. When the inner pot is a rectangular parallelepiped or other shapes, the placement position surrounded by the fixed base 11 and the side plate 21 is a corresponding rectangular parallelepiped or other shapes.

[0057] Regardless of the shape of the placement position, the side panels 21 can be used as a unified extension, or divided into an even number of side panels 21 evenly and symmetrically distributed at the edge of the fixed base 11. Figure 1 As shown, in the present application, the number of the side panels 21 can be set to four, and the four side panels 21 are symmetrically distributed at the edge positions of the fixed base 11 in a cross shape.

[0058] When the side panels 21 are separated into multiple pieces, the space enclosed by the side panels 21 and the fixed base 11 is not a sealed structure. It is only necessary to ensure that when the inner pot is placed in the placement position, the side panels 21 can limit the local side walls of the inner pot and ensure that the inner pot will not be thrown out during the rotation process. It is not required that the side panels 21 limit each position of the outer wall of the inner pot at the same time.

[0059] Furthermore, the side plate 21 is located in the slide groove 15 , and the slide groove 15 extends toward the center of the fixed base 11 .

[0060] In the present application, the position of the side plate 21 and the center of the fixed base can be relatively changed. The side plate 21 is located in the chute 15 and can slide along the chute 15. The position of the side plate 21 in the chute 15 needs to be determined according to the outer diameter of the inner pot. After the outer diameter of the inner pot is determined, the position of the side plate 21 in the chute 15 is moved so that the distance between the side plate 21 and the center point of the fixed base is equal to the outer diameter of the inner pot. The extension direction of the chute 15 is the direction from the edge of the fixed base to the center of the fixed base. For example, when the fixed base 11 is circular, the extension direction of the chute 15 is the radius direction of the circular fixed base 11. When the position of the side plate 21 needs to be adjusted, the position of all the side plates 21 in the chute 15 needs to be adjusted at the same time to ensure that the distance of all the chute 15 from the center point of the fixed base is adapted to the size of the inner pot. The present application sets the position of the side plate 21 to be slidable, which can expand the application range of the fixing device. When the size of the inner pot to be fixed is different, it is only necessary to move the side plate 21 along the chute 15 to adapt to the inner pots of different sizes. Once the size of the inner pot is determined and the position of the side panel 21 in the slide groove 15 is determined, the side panel 21 can be fixed in the slide groove 15 by tightening screws to ensure that the position of the side panel 21 remains fixed relative to the slide groove 15 while the inner pot of the corresponding size is being fixed.

[0061] Furthermore, in the present application, a mounting plate 14 is provided at the edge of the fixed base 11 , and the slide groove 15 is located in the mounting plate 14 .

[0062] When the fixed base 11 is a circular structure, the mounting plate 14 is symmetrically arranged at the edge of the fixed base 11. The mounting plate 14 may be a rectangular plate structure, and the adjacent fixed bases 11 are fixed at the edge of the fixed base 11 at 90 degrees. Figure 1 As shown, the side of the mounting plate 14 away from the fixed base 11 can be set to an arc-shaped structure to prevent the edge of the mounting plate 14 from being too sharp and causing damage to the staff or devices outside the fixing device.

[0063] In the present application, the mounting plate 14 and the fixed base 11 may be an integrally formed structure. The number of mounting plates 14 corresponds to the number of side plates 21, which may be four, six or eight, and the plurality of mounting plates 14 are evenly distributed on the outer periphery of the fixed base 11, and the plurality of mounting plates 14 are symmetrically centered around the center point of the fixed base 11.

[0064] Furthermore, the slide groove 15 is provided with scale lines 16 extending along a first direction, and the first direction is parallel to the extending direction of the slide groove 15 .

[0065] When the fixed base 11 is a circular structure, the extension direction of the chute 15 is the radius direction of the circular fixed base 11, and the first direction is also the radius direction of the circular fixed base 11. The extension direction of the scale lines 16 themselves is perpendicular to the first direction, and a fixed distance is maintained between adjacent scale lines 16. The scale lines 16 can be used to indicate the distance from the current position to the center of the fixed base 11. When the side panel 21 slides in the chute 15, the distance between the side panel 21 and the center of the fixed base 11 can be determined by looking at which scale line 16 the side panel 21 slides to.

[0066] The present application simultaneously sets scale lines 16 in each slide groove 15. By moving the side panel 21 to the fixed scale line 16 position, it can ensure that the distances between multiple slide grooves 15 and the center of the fixed base are the same. There is no need to measure the position of the side panel 21 when moving the position of the side panel 21. The scale line 16 can be used to ensure that the position of the side panel 21 is adapted to the size of the inner pot, thereby improving the efficiency of adjusting the side panel 21.

[0067] Furthermore, the side of the side panel 21 of the present application close to the center of the fixed base includes a first end face 22 and a second end face 23, the first end face 22 is arranged perpendicular to the fixed base 11, and the first end face 22 is located at the bottom of the side panel 21, the second end face 23 is an arc-shaped structure, and the second end face 23 extends from the top of the first end face 22 toward a direction away from the center point of the fixed base.

[0068] In the present application, the side plate 21 is fixed on the upper surface of the fixed base 11, and the bottom of the side plate 21 refers to the side close to the fixed base 11 in the vertical direction. The first end face 22 is a vertical end face, which is used to abut and fix the outer wall of the inner pot. The second end face 23 is an arc-shaped structure, and the second end face 23 is covered with a flexible material, such as a protective layer of high-quality flannel. When the inner pot is placed above the placement position, the position of the inner pot is not uniquely determined. Since the arc-shaped structure expands outward, the area above the placement position is larger than the bottom cross-sectional area of ​​the inner pot. At this time, whether the inner pot is held by hand or clamped by a mechanical arm, it can be adjusted and moved in the space surrounded by the arc-shaped structure. When the inner pot contacts the second end face 23 on one of the side plates 21, the mechanical arm releases the inner pot. At this time, under the action of gravity, the inner pot descends. During the descent, the arc-shaped second end face 23 can adjust the position of the inner pot, so that when the bottom of the inner pot abuts against the fixed base 11, the axis of the inner pot coincides with the axis of the fixed base 11, and the position of the inner pot is uniquely fixed. The arc-shaped second end surface 23 of the present application can facilitate the inner pot to slide into the placement position, and after being covered with the protective layer, it can prevent the outer wall of the inner pot from being scratched, thereby protecting the outer wall of the inner pot.

[0069] Example 3

[0070] like Figure 1-Figure 8As shown, an inner pot fixing device is connected to a rotating drive member, specifically comprising a fixed base 11 and a side plate 21, wherein the fixed base 11 and the side plate 21 surround a placement position for the inner pot; an adsorption component is arranged in the fixed base 11, and the side plate 21 is evenly distributed on the edge of the fixed base 11; and is used to limit the side wall of the inner pot.

[0071] In the present application, the adsorption component is used to adsorb and fix the inner pot on the placement position, which can be an adsorption component such as a magnet 12, or a vacuum adsorption component or other clamping components.

[0072] As a specific embodiment, the adsorption component in the present application is a magnet 12. Correspondingly, the bottom of the inner pot is made of iron. When the inner pot is placed in the placement position, the magnet 12 can adsorb the bottom of the inner pot, so that the position of the inner pot is uniquely fixed. The magnet 12 is used as the adsorption component, which has a simple structure and occupies a small area, and can ensure that the fixing device can effectively fix the inner pot.

[0073] like Figure 5 and Figure 6 As shown, when the fixed base 11 is a circular structure, the magnet 12 can be a cylindrical structure and installed at the center position of the fixed base 11; the reason for installing it at the center position is to fix the central area of ​​the inner pot. When the inner pot is in the process of rotating spraying, each position of the central area is evenly adsorbed, which can ensure that the axis line of the inner pot always coincides with the axis line of the fixed base 11 during the rotation process.

[0074] In actual operation, the cross-sectional area of ​​the magnet 12 can be set to be equal to the cross-sectional area of ​​the bottom of the inner pot, or it can be set to be smaller than the cross-sectional area of ​​the bottom of the inner pot; since the inner pot is a hollow structure, only the magnet 12 in the center part is needed to fix the inner pot in the fixed base 11. Therefore, the magnet 12 can be set in the center area of ​​the fixed base 11, and the gasket 13 can be set on the edge area of ​​the fixed base 11.

[0075] The gasket 13 can be made of flexible material. When the inner pot is placed on the placement position, the inner pot is moved to the top of the placement position under the clamping action of the robot. When the inner pot contacts the side panel 21, the robot can release the clamping. At this time, the inner pot will fall under the action of gravity. The gasket 13 can provide a buffering and protective effect for the inner pot, preventing the inner pot from colliding with the fixed base 11 when falling and causing scratches.

[0076] As another embodiment, the adsorption component in the present application adopts vacuum adsorption, specifically including a suction cup and a vacuum generator. The vacuum generator and the suction cup are connected through a vacuum channel. When the inner pot is in the placement position, the vacuum generator is operated, so that the suction cup generates suction on the bottom of the inner pot, thereby fixing the inner pot.

[0077] Example 4

[0078] like Figure 1-Figure 8 As shown, an inner pot spraying device includes the inner pot fixing device as described above. The inner pot fixing device is connected to a rotating driving member, and includes a fixing base 11 and a side plate 21, wherein the fixing base 11 and the side plate 21 surround a placement position of the inner pot; an adsorption component is arranged in the fixing base 11, and the side plates 21 are evenly distributed on the edge of the fixing base 11; and are used to limit the side wall of the inner pot.

[0079] In the present application, the inner pot is a hollow cylindrical structure, and the placement position is adapted to the shape of the inner pot, and the placement position is also a circular structure. The placement position is surrounded by a fixed base 11 and a side plate 21. The fixed base is a circular base, and a magnet 12 is set at the center of the fixed base 11 as an adsorption component, and a gasket 13 is set at the edge of the fixed base 11.

[0080] The magnet 12 fixes the central area of ​​the inner pot. When the inner pot is in the process of rotating spraying, each position of the central area is uniformly adsorbed, which can ensure that the axis of the inner pot always coincides with the axis of the fixed base 11 during the rotation of the inner pot. The gasket 13 can be made of a flexible material. When the inner pot is placed on the placement position, the inner pot is moved to the top of the placement position under the clamping action of the manipulator. When the inner pot contacts the side plate 21, the manipulator can release the clamping. At this time, the inner pot will fall under the action of gravity. The gasket 13 can provide a buffering protection for the inner pot to prevent the inner pot from colliding with the fixed base 11 when it falls and causing scratches.

[0081] like Figure 5 and Figure 6 As shown, the outer diameter of the magnet 12 is about 25 mm, and the center of the magnet 12 is fixed in the fixed base 11 by a fixing bolt. Figure 7 and Figure 8 As shown, the gasket 13 is an annular structure, and the outer diameter of the gasket 13 is 160 mm and the inner diameter is 100 mm. A transition zone is also provided between the gasket 13 and the magnet 12, wherein the upper surfaces of the magnet 12, the transition zone and the gasket 13 are kept flush or form an arc that matches the bottom of the inner pot, so that the inner pot and the fixed base 11 fit perfectly. Among them, the transition zone is not provided with a magnet 12 and a gasket 13, and a QR code or information such as a material number can be provided.

[0082] Furthermore, a mounting plate 14 is provided at the edge of the fixed base 11, and the slide groove 15 is located in the mounting plate 14. The mounting plate 14 can be a rectangular plate-shaped structure, and adjacent fixed bases 11 are fixed at the edge of the fixed base 11 at 90 degrees. Figure 1As shown, the side of the mounting plate 14 away from the fixed base 11 can be set as an arc structure to prevent the edge of the mounting plate 14 from being too sharp and causing damage to the staff or devices outside the fixing device. The mounting plate 14 and the fixed base 11 can be an integrally formed structure.

[0083] The slide groove 15 is located on the mounting plate 14. Since the mounting plate 14 and the fixed base 11 are an integrated structure, the slide groove 15 can extend into the fixed base 11. Figure 1 As shown, when the slide slot 15 extends into the fixed base 11 , a groove corresponding to the slide slot 15 is provided in the gasket 13 , and the groove can be understood as a part of the slide slot 15 .

[0084] The position of the side plate 21 and the center of the fixed base can be relatively changed. The side plate 21 is located in the chute 15 and can slide along the chute 15. The position of the side plate 21 in the chute 15 needs to be determined according to the outer diameter of the inner pot. After the outer diameter of the inner pot is determined, the position of the side plate 21 in the chute 15 is moved so that the distance between the side plate 21 and the center point of the fixed base is equal to the outer diameter of the inner pot. The extension direction of the chute 15 is the direction from the edge of the fixed base to the center of the fixed base. For example, when the fixed base 11 is circular, the extension direction of the chute 15 is the radius direction of the circular fixed base 11. When the position of the side plate 21 needs to be adjusted, the position of all the side plates 21 in the chute 15 needs to be adjusted at the same time to ensure that the distance of all the chute 15 from the center point of the fixed base is adapted to the size of the inner pot. The present application sets the position of the side plate 21 to be slidable, which can expand the application range of the fixing device. When the size of the inner pot to be fixed is different, it is only necessary to move the side plate 21 along the chute 15 to adapt to the inner pots of different sizes. Once the size of the inner pot is determined and the position of the side panel 21 in the slide groove 15 is determined, the side panel 21 can be fixed in the slide groove 15 by tightening screws to ensure that the position of the side panel 21 remains fixed relative to the slide groove 15 while the inner pot of the corresponding size is being fixed.

[0085] The extending direction of the chute 15 is the radial direction of the circular fixed base 11, and the first direction is also the radial direction of the circular fixed base 11. The extending direction of the scale lines 16 themselves is perpendicular to the first direction, and a fixed distance is maintained between adjacent scale lines 16. The scale lines 16 can be used to indicate the distance from the current position to the center of the fixed base 11. When the side panel 21 slides in the chute 15, the distance between the side panel 21 and the center of the fixed base 11 can be determined by looking at which scale line 16 the side panel 21 slides to.

[0086] The side panel 21 of the present application includes a first end face 22 and a second end face 23 on one side close to the center of the fixed base. The first end face 22 is arranged perpendicular to the fixed base 11 and is located at the bottom of the side panel 21. The second end face 23 is an arc-shaped structure and extends from the top of the first end face 22 in a direction away from the center point of the fixed base.

[0087] In the present application, the side plate 21 is fixed on the upper surface of the fixed base 11, and the bottom of the side plate 21 refers to the side close to the fixed base 11 in the vertical direction. The first end face 22 is a vertical end face, which is used to abut and fix the outer wall of the inner pot. The second end face 23 is an arc-shaped structure, and the second end face 23 is covered with a flexible material, such as a protective layer of high-quality flannel. When the inner pot is placed above the placement position, the position of the inner pot is not uniquely determined. Since the arc-shaped structure expands outward, the area above the placement position is larger than the bottom cross-sectional area of ​​the inner pot. At this time, whether the inner pot is held by hand or clamped by a mechanical arm, it can be adjusted and moved in the space surrounded by the arc-shaped structure. When the inner pot contacts the second end face 23 on one of the side plates 21, the mechanical arm releases the inner pot. At this time, under the action of gravity, the inner pot descends. During the descent, the arc-shaped second end face 23 can adjust the position of the inner pot, so that when the bottom of the inner pot abuts against the fixed base 11, the axis of the inner pot coincides with the axis of the fixed base 11, and the position of the inner pot is uniquely fixed. The arc-shaped second end surface 23 of the present application can facilitate the inner pot to slide into the placement position, and after being covered with the protective layer, it can prevent the outer wall of the inner pot from being scratched, thereby protecting the outer wall of the inner pot.

[0088] After the inner pot is fixed by the magnet 12 and the side plate 21, the rotary drive member drives the fixed base 11 to rotate, and the spray head is fixed on the side of the fixed base 11. The spray head is aimed at a specific area in the inner pot. By rotating the inner pot, uniform spraying of the inner pot can be achieved.
