[0021] All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, unless otherwise defined. The terminology used in the description of the present invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] As shown in FIG. 1, a toothpaste device 10 for use in a kindergarten of the present invention includes: a multi-degree-of-freedom robot 100, a toothpaste clamping device 200, a toothpaste device 300, and a multi-degree-of-freedom robot 100 is provided in the toothpaste The device 200 is below the toothpaste clamping device 300.

[0023] The multi-degree-of-freedom manipulator 100 includes: a fixed base 110, a rotating arm 120, and a rotating claw 130. The fixed base 110 has a fixed connecting end 111 and a rotating swinging end 112, and the rotating swinging end 112 drives the rotating arm 120 to be fixedly connected. The end 111 is rotated, and the rotating swing end 112 and the rotating claw 130 are respectively hinged to both ends of the rotating arm 120. The rotary claw 130 has a toothbrush clamping portion 131 and a screw drive portion 132 that drives the toothbrush clamping portion 1 31 to reciprocate axially along the screw shaft.

[0024] Referring to FIG. 3 and FIG. 4 together, the toothpaste clamping device 200 includes: a rolling shaft 210, a clamping shaft 220, a rolling shaft driving motor (not shown), a mounting table 240, and the mounting base 240 has a rotating shaft mounting groove. 241, the surface of the clamping shaft 22 0 and the rolling shaft 210 is a straight knurling structure. The rolling shaft 210 and the clamping shaft 220 are disposed in the rotating shaft mounting groove 241, and a clamping gap 221 is formed between the rolling shaft 210 and the clamping shaft 220. The rolling shaft drive motor drives the rolling shaft 210 to rotate in the shaft mounting groove 241.

2, the toothpaste device 300 includes: a driving cylinder 310, an ejection mechanism 320, and a toothpaste pressing seat 330. The driving cylinder 310 is hinged with the pushing transmission mechanism 320, and the toothpaste extrusion base 330 has a toothpaste pressing portion 3. 31 and the hinged slot 332, the push-out transmission mechanism 320 includes: a swing link 321, a drive link 322, and a limit The positional link 323, the driving cylinder 322 and the swinging link 323 are hinged in the middle, the limiting link 323 is hinged at the middle of the driving link 322, and the swinging link 321 and the hinged long groove 332 are respectively hinged at both ends of the driving link 322.

When the driving cylinder 310 is operated, the swinging link 321 is rotated to drive the driving link 322 to swing under the action of the limiting link 323, and the toothpaste pressing portion 331 is pushed or extended by the hinged slot 332. return.

[0027] In the embodiment, the clamping shaft 220 of the toothpaste clamping device 200 is movably mounted in the rotating shaft mounting slot 241, and a clamping gap 221 is formed between the clamping shaft 220 and the rolling shaft 210, so as to facilitate the toothpaste. The housing is inserted between the clamping shaft 220 and the rolling shaft 210 through the clamping gap 221. Since the toothpaste housing itself has a thickness, the clamping shaft 220 and the rolling shaft 210 generate a clamping force to the toothpaste housing, and The surface of the shaft 220 and the rolling shaft 210 adopts a straight knurling structure to enhance the friction against the toothpaste shell, so that the toothpaste can be fixed between the clamping shaft 220 and the rolling shaft 210 under the frictional force, when the rolling drive drives the rolling When the pressing shaft 210 rotates, the tail portion of the toothpaste shell will steer upwardly and vertically upwardly under the frictional force, and at the same time as the toothpaste moves, the clamping shaft 220 and the rolling shaft 210 will roll the toothpaste. The toothpaste in the toothpaste case is driven to flow toward the front end of the toothpaste case until the front portion of the toothpaste case is filled, and the rolling drive stops rotating.

[0028] The starting device 吋, the rolling drive drives the rotating shaft 210 to rotate, the tail portion of the toothpaste housing moves vertically with the rolling shaft 210 under the frictional force, and at the same time the toothpaste moves, the clamping shaft 220 The toothpaste is rolled with the rolling shaft 210 to drive the toothpaste in the toothpaste case toward the front end of the toothpaste case until the front portion of the toothpaste case is filled.

[0029] The cymbal drive cylinder 310 drives the toothpaste squeeze seat 330 to extend by the push-out transmission mechanism 320, so that the toothpaste squeezing portion 331 presses the toothpaste. Simultaneously, the screw driving portion 132 on the rotary claw 130 drives the toothbrush clamping portion 131 to extend along the screw shaft so that the extruded toothpaste is evenly distributed on the toothbrush. The driving cylinder 310 is driven to retract the toothpaste pressing seat 330 by the push-out driving mechanism 320, thereby moving the toothpaste pressing portion 331 away from the toothpaste. At the same time, the base rotating end 112 drives the intermediate rotating arm 120 to rotate around the base fixed end 111, and the rotary actuator 121 on the intermediate rotating arm 120 starts to operate, so that the toothbrush fixing claw 130 is lifted up to the user, waiting for use. Remove the toothbrush.

[0030] It should be particularly noted that the shape of the toothpaste shell on the market is irregular, and the toothpaste device 300 in the present embodiment defines the stroke of the toothpaste pressing portion 331 by driving the cylinder 310, thereby making each squeeze The toothpaste has the same distance, and after each use of the toothpaste, the toothpaste will move toward the rear end of the toothpaste case under the action of atmospheric pressure. The toothpaste clamping device 200 will roll the toothpaste every time the system is started. Drive The toothpaste on the back of the toothpaste case is transferred to the front end of the toothpaste case to achieve a state in which the toothpaste is filled in the front of each toothpaste toothpaste case, and the toothpaste clamping device 200 and the toothpaste device 300 are mutually matched. The amount of toothpaste extruded each time is the same. The toothpaste clamping device 200 performs a rolling action on the toothpaste to ensure that there is no residual toothpaste at the tail of the toothpaste casing, thereby achieving the purpose of reducing waste.

[0031] A toothpaste device 10 for use in a kindergarten, by providing a multi-degree-of-freedom robot 100, a toothpaste device 200, and a toothpaste clamping device 300, realizes automatic toothpaste action, limiting the amount of toothpaste per time, reducing Waste, help children learn to brush their teeth, use the automation equipment to arouse the curiosity of children, and guide them to the enthusiasm of learning knowledge.

The above-mentioned embodiments are merely illustrative of several embodiments of the present invention, and the description thereof is more specific and detailed, but is not to be construed as limiting the scope of the invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of the invention should be determined by the appended claims.
