Detailed Description

The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.

As shown in fig. 1 and 2, the dish gripper comprises two gripping fingers, and the gripping fingers are movably arranged on the fixing piece, so that the two gripping fingers can move relatively to move to close or move away from each other to open by moving the gripping fingers, and the accommodating hole is correspondingly reduced or enlarged. The opposite sides of the two grabbing fingers are sunken to form a concave part, the concave parts of the two grabbing fingers are matched to form a containing hole used for containing a bowl and a dish, the bottom of the concave part is circular, the diameter of the bottom of the concave part is greater than or equal to 50mm and less than or equal to 160mm, and the diameter of the bottom of the concave part can be 50mm, 60mm, 70 mm, 80 mm, 90mm, 100 mm, 110 mm, 120 mm, 130mm, 140 mm or 150 mm. If the diameter of the bottom of the concave part is too large, only two parts of the bowl and dish may contact with the hand grip after the bowl and dish are gripped if the diameter of the bowl and dish is smaller than the diameter of the bottom of the concave part, so that the bowl and dish are easily shaken, and therefore, the diameter of the bottom of the concave part is preferably smaller than the diameter of the bowl and dish to be gripped.

The grasping fingers are movably arranged on the fixing piece, can be arranged on the fixing piece in a pivoting mode, can be arranged on the fixing piece in a linear motion mode along a certain direction, or can be arranged on the fixing piece in other motion modes as long as the two grasping fingers can move relatively to move to be closed or move back to be opened.

The grabbing fingers are movably arranged on the fixing piece, the fixing piece comprises an upper plate and a lower plate, the upper plate and the lower plate are arranged in parallel and spaced, the connecting end parts of the two grabbing fingers are arranged in a space formed by the upper plate and the lower plate in a spaced mode, the grabbing fingers are arranged on the upper plate in a pivoting mode, specifically, the lower surface of the upper plate is fixedly provided with two pivot shafts, the connecting end parts of the grabbing fingers are provided with shaft holes, and the two pivot shafts are respectively matched with the two shaft holes; be provided with the elliptical plate between grabbing finger and the upper plate, grab and be provided with the gyro wheel on the finger, the gyro wheel is arranged between grabbing the shaft hole of finger and grabbing the unsettled tip of finger, and two gyro wheels cooperate with the side of elliptical plate to, the distance of two gyro wheels is less than the length of elliptical plate and is greater than the width of elliptical plate so that when the elliptical plate rotated, thereby the elliptical plate extrusion gyro wheel makes grabbing the finger rotate around pivot or shaft hole.

In order to ensure that the idler wheel is always attached to the side face of the elliptical plate, an elastic piece is arranged between the two grabbing fingers, one end of the elastic piece is fixed to one grabbing finger, the other end of the elastic piece is fixed to the other grabbing finger, the fixed positions of the elastic piece and the grabbing fingers are located between the idler wheel and the suspended end portion of the grabbing fingers, the elastic piece is always in a stretching state, namely under the action of the elastic piece, the two grabbing fingers tend to be folded, the two idler wheels are tightly attached to the side face of the elliptical plate, folding and unfolding of the two grabbing fingers can be achieved as long as the elliptical plate is driven to rotate, and the elastic piece can also guarantee that the grabbing fingers can hold the bowl plate tightly in real time. Specifically, the elastic member may be a spring or a rubber band, but may also be other members having elasticity. The center of rotation of the elliptical plate is the central axis of the elliptical plate. From this, can two grab finger simultaneous movement of synchronous drive, simultaneously, can also guarantee to grab and hold bowl dish tightly that the finger can be tight, compare in traditional gear drive, this application does not need the motor to last the power supply action after firmly grasping the bowl dish, can be energy-conserving to, more reliable.

Of course, the elastic member may be provided in another manner. Specifically, the elastic component is in compression state, and the shaft hole setting is between the unsettled tip of elastic component and grabbing finger, the one end and a grabbing finger of elastic component are fixed, the other end and another grabbing finger of elastic component are fixed, and the elastic component is in compression state, therefore the elastic component makes two unsettled tips of grabbing finger have the trend of folding, two grab fingers can firmly grasp the elliptical plate always promptly, in addition can not adopt the gyro wheel, but the elliptical plate directly with grab two medial surface contacts of finger can, it is rolling friction to adopt the gyro wheel to mainly be become sliding friction, reduce frictional force.

Of course, the gripping fingers are pivotally arranged on the fixed part, and there may be other driving means, such as a gear driving means, besides the above-mentioned cam cooperating with the elastic member to drive the gripping fingers to rotate to close/open. Besides the above-mentioned gripping fingers moving in a rotating manner, the two gripping fingers can also move linearly to close and hold or open, and the specific driving manner can be seen in the driving manner of various mechanical claws.

As shown in fig. 1 and 2, each grabbing finger is provided with 3V-shaped clamps, the opening of each V-shaped clamp on one grabbing finger faces to the other grabbing finger, so that the V-shaped clamps of the two grabbing fingers face to each other, the opening of the V-shaped clamp can hold the edge of the opening of the bowl when the grabbing fingers are folded, as shown in fig. 1 and 2, the V-shaped clamps are arranged on the side faces of the grabbing fingers opposite to the other grabbing finger, the V-shaped clamps can only accommodate the bowl turned over from the edge of the opening, and the edge of the opening of the bowl after the two grabbing fingers are closed to hold the bowl is only held by the V-shaped clamps, so that the bowl cannot fall off and cannot be turned over.

The material of grabbing finger is stainless steel, resin, plastics, silica gel or melamine, the material of V type card is stainless steel, resin, plastics, silica gel or melamine.

Regarding the specific structure of the V-shaped clip, two forms can be adopted according to different bowl mouth shapes. The bowl mouth mainly has a reverse mouth shape and an inclined mouth shape, the reverse mouth shape means that the mouth edge of the bowl is outwards turned to be different from the inclination of the bowl body, and the bowl is the reverse mouth shape as shown in figure 4; the bevel-mouth bowl refers to a bowl with the mouth edge not turned outwards and the outer side surface of the bowl mouth is inclined, and the bowl shown in figure 6 is the bevel-mouth bowl.

As shown in fig. 1-4, the structure form of the V-shaped card is a structure form of a V-shaped card, specifically, the inner side surface of the upper claw is arranged obliquely upwards and has an included angle of R1 with the horizontal plane, R1 is equal to or larger than 30 degrees and equal to or smaller than 65 degrees, R1 can be 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees or 65 degrees, the inner side surface of the lower claw is arranged obliquely downwards and has an included angle of R2 with the horizontal plane, R2 is equal to or larger than 30 degrees and equal to or smaller than 65 degrees, and both the V-shaped card in the scheme can be used for grabbing a bowl with a reversed mouth shape and an oblique mouth shape, and. As shown in figure 4, after the grabbing finger with the V-shaped clamp tightly holds the bowl, the upper claw of the V-shaped clamp is in contact with the upper semi-circular arc surface of the mouth edge of the bowl, the lower claw is in contact with the lower semi-circular arc surface of the mouth edge of the bowl, the lower claw bears the gravity of the bowl, the upper claw bears the pressure of tightly holding the bowl, and the upper claw and the lower claw act together to tightly hold the bowl, so that the bowl cannot vertically shake in the grabbing finger, and the bowl can be better and more stably grabbed.

Certainly, in the above scheme, the inner side surface of the lower jaw is completely attached to the lower side surface of the mouth edge of the bowl, so that the lower jaw is in surface-to-surface contact, and the grasping is firmer, but because the mouth edge of the bowl with the inverted mouth shape is turned outwards, the outer side surface of the mouth edge is a surface approximate to a circular arc, if the complete attachment is achieved, the side surface of the lower jaw of the V-shaped clamp needs to be made into a surface approximate to a circular arc, the processing difficulty is very high, the cost is very high, and therefore, the side door surface of the lower jaw is preferably a plane, and the inner side surface of the lower jaw shown in fig. 4 is a plane.

Of course, if the bowl is a bevel-mouth bowl, as shown in fig. 5, the lower jaw of the V-shaped clamp is a plane, the inner side surface of the lower jaw is arranged obliquely downward and has an included angle R2 with the horizontal plane, R2 is greater than or equal to 10 degrees and less than or equal to 65 degrees, and R2 can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees or 65 degrees. For the upper jaw of the V-shaped card, the inner side of the upper jaw is preferably horizontal. The V-shaped clamp is used for accommodating the mouth edge of a bowl and a plate, the mouth edge of the bowl and the plate is clamped through the V-shaped clamp to grab the bowl and the plate, the V-shaped clamp is generally adopted as shown in figure 4, however, due to the problem of the processing precision of the bowl and the plate, the roundness of the bowl and the plate is generally difficult to achieve very accurately, and therefore when the V-shaped clamp in figure 4 is adopted to contact the mouth edge of the bowl and the plate, due to poor roundness precision of the bowl and the plate, only 3V-shaped clamps are needed to actually grab the bowl and the plate after grabbing, and the food filled in the bowl and the plate is easily scattered under the condition that the bowl and the plate shake in the grabbing and moving path. Compare in the circularity precision of bowl dish, the levelness precision of bowl dish mouth border upper surface is better, and processing is guaranteed more easily, from this, the medial surface level of last claw sets up to with the last side contact on bowl dish mouth border, thereby grab the bowl dish that can be more firm with bowl dish contact more V type card on the finger, splendid attire food in the bowl dish is difficult to unrestrained.
