[0002] Automatic cooking equipment is a kind of kitchen cooking appliance that can realize automatic feeding and automatic stir-frying. When the automatic cooking equipment is frying dishes, it is generally necessary to set up multiple material boxes to store the various raw materials needed for the dishes. The feeding mechanism of the automatic cooking equipment will clamp and transfer the material boxes containing the corresponding ingredients to the pouring position in the corresponding order according to the preset program, and flip the material box to pour the ingredients into the wok through the opening of the material box.

[0051] Figures 1 to 27 The structure diagram of the material box clamp transmission mechanism and the fixed clamp and the movable clamp shown in some embodiments of the present application is as follows. Figures 1 to 27 The material box clamp transmission mechanism, fixed clamp and movable clamp involved in this application are introduced. It should be noted that: Figures 1 to 27 This is only an example, and does not limit the specific shapes and structures of the material box clamp transmission mechanism and the fixed clamp and movable clamp.

[0052] See also Figures 1 to 4 In this embodiment, the material box clamp transmission mechanism includes a nut assembly 2, a clamp seat 1 and a screw 6; the nut assembly 2 includes a rotating sleeve 201, a connecting shaft 202 and a nut sleeve 203; the connecting shaft 202 passes through the rotating sleeve 201 and is clearance-matched with the rotating sleeve 201, and when the connecting shaft 202 rotates, it can drive the rotating sleeve 201 to rotate; a guide groove 3 is provided on the outer periphery of the nut sleeve 203, and the guide groove 3 includes a linear groove 301 and a spiral groove 302; the clamp seat 1 includes a base 103 and a side plate 101, and a blocking rod 5 is provided on the base 103, and the end of the blocking rod 5 extends into the guide groove 3; a through hole is opened on the side plate 101, and the rotating sleeve 201 is rotatably installed in the through hole; a threaded hole is provided at the end of the nut sleeve 203 for connecting with the screw 6, and the screw 6 can be driven to rotate by the driving mechanism 4.

[0053] In this embodiment, the transmission principle of the material box transmission mechanism is: the driving mechanism 4 drives the screw 6 to rotate, and since the screw hole is threadedly connected with the nut sleeve 203, the end of the blocking rod 5 extends into the guide groove 3 to limit the nut sleeve 203, and a screw-like structure is formed between the screw 6, the nut assembly 2 and the blocking rod 5. And since the guide groove 3 provided on the outer periphery of the nut sleeve 203 includes a linear groove 301 and a spiral groove 302, the nut sleeve 203 has the following two motion forms under the drive of the screw 6:

[0054] First, when the blocking rod 5 is located in the linear groove 301, the nut sleeve 203 performs linear motion, and because the connecting shaft 202 and the rotating sleeve 201 are clearance-matched, the linear motion of the nut sleeve 203 will drive the connecting shaft 202 to perform linear motion, and the rotating sleeve 201 does not rotate at this time;

[0055] Second, when the blocking rod 5 is located in the spiral groove 302, the nut sleeve 203 will rotate while performing linear motion. At this time, since the rotation of the connecting shaft 202 can drive the rotating sleeve 201 to rotate, the connecting shaft 202 will also synchronously drive the rotating sleeve 201 to rotate while performing linear motion.

[0056] Specifically, in order to enable the connecting shaft 202 to drive the rotating sleeve 201 to rotate, the connecting shaft 202 can be set as a prism structure and be installed in cooperation with the prism hole set in the rotating sleeve 201. Figure 3 In the structure shown, an assembly plane is cut on the connecting shaft 202. After the connecting shaft 202 under this structure is matched with the rotating sleeve 201, it can also drive the rotating sleeve 201 to rotate.

[0057] Preferably, see Figure 4 The rotating sleeve 201 is rotatably mounted on the through hole of the side plate 101 through the bearing 102. The bearing 102 can reduce the resistance of the rotating sleeve 201 when rotating, and improve its service life and reliability.

[0058] Preferably, the driving mechanism 4 is a motor, which is fixedly mounted on the base 103 , and the output shaft of the motor is fixedly connected to the screw 6 .

[0059] Specifically, the motor output shaft and the screw rod 6 may be connected by a coupling, screws or welding.

[0060] Specifically, in order to more accurately control the rotation stroke of the screw rod 6, a servo motor may be used as the motor.

[0061] Preferably, the fixture seat 1 is provided with an outer cover 11 for wrapping the nut assembly 2, the screw rod 6 and the drive mechanism 4. After the outer cover 11 wraps the nut assembly 2, the screw rod 6 and the drive mechanism 4, it can play the role of dustproof, waterproof and anti-accidental touch, and can also make the entire material box fixture transmission mechanism more beautiful.

[0062] The above-mentioned material box 8 clamp transmission mechanism has a simple structure, which can effectively reduce the initial production cost and the later maintenance cost. And its relatively simple structure can also reduce the probability of its failure and improve its reliability.

[0063] The following will describe the fixed clamp, movable clamp, and eccentric clamp formed by the above-mentioned material box clamp transmission mechanism. As known from the prior art, the feeding mechanism of the existing automatic cooking equipment generally includes a material box conveying mechanism and a feeding mechanism with a material box clamp, wherein the material box conveying mechanism is used to convey the material box 8 to the position to be clamped, so that the feeding mechanism can clamp it. In addition to the material box clamp, the feeding mechanism is also provided with a transfer mechanism, which is used to transfer the clamped material box 8 to the pouring position. Specifically, the transfer mechanism can be a robotic arm.

[0064] See also Figures 5 and 6 In this embodiment, the fixed clamp includes a fixed clamp 7 and any one of the above-mentioned material box clamp transmission mechanisms, and the fixed clamp 7 is fixedly connected to the rotating sleeve 201.

[0065] In this embodiment, combined with Figure 7 The fixed clamp has a material box 8 structure and its operating principle is: first, the material box conveying mechanism can be used to adjust the position of the material box 8 or the material feeding mechanism can be used to adjust the position of the clamp, so that the fixed clamp head 7 of the clamp is clamped into the clamping groove of the material box 8. Subsequently, the material box clamp transmission mechanism is started, and at this time, the connecting shaft 202 first makes a linear motion and extends into the clamping hole 802 set in the material box 8, and the connecting shaft 202 cooperates with the fixed clamp head 7 to complete the clamping action of the material box 8.

[0066] The clamped material box 8 is then transferred to the pouring position through the transfer mechanism, and the material box 8 clamp transmission mechanism is started again. At this time, the connecting shaft 202 will simultaneously drive the rotating sleeve 201 to rotate while performing linear motion. The rotation of the rotating sleeve 201 will drive the fixed clamp 7 fixed thereon to rotate, so that under the cooperation of the fixed clamp 7 and the connecting shaft 202, the clamped material box 8 is turned over, so that the cooking ingredients in the material box 8 are poured into the pot, completing the turning action.

[0067] Furthermore, since the connecting shaft 202 will continue to make linear motion while rotating when flipping, in order to avoid interference of the material box 8 with the connecting shaft 202, the depth of the clamping hole 802 should leave a margin for the connecting shaft 202 to move.

[0068] After the material is poured, the material box 8 can be put back to the starting position by reversing the above operation.

[0069] Specifically, from the above embodiment, it can be known that in order to enable the connecting shaft 202 to drive the rotating sleeve 201 to rotate, the connecting shaft 202 is a non-cylindrical body, so the clamping hole 802 adapted thereto is also a non-circular hole shape. In this way, when the clamp seat 1 rotates, the connecting shaft 202 can drive the material box 8 to flip.

[0070] See also Figures 8 to 12 In some embodiments, the fixed chuck 7 is fixedly connected to the rotating sleeve 201 through the chuck seat 10, and the fixed chuck 7 is located at the top of the chuck seat 10; a limiting groove 1002 and a reversing seat 14 fixedly connected to the connecting shaft 202 are provided in the chuck seat 10, a reversing rod 13 is provided in the limiting groove 1002, and a reversing groove 1401 is provided on the side of the reversing seat 14; a pin shaft 1301 extending into the reversing groove 1401 is provided at the lower end of the reversing rod 13, and the reversing seat 14 drives the reversing rod 13 to move in the vertical direction through the reversing groove 1401 and the pin shaft 1301.

[0071] In this embodiment, the reversing structure is formed by the reversing seat 14 and the reversing rod 13, thereby forming an eccentric fixed clamp, and its operating principle is: first, the position of the material box 8 can be adjusted by the material box conveying mechanism or the position of the clamp can be adjusted by the feeding mechanism, so that the fixed clamp head 7 of the clamp is clamped into the clamping groove set in the material box 8. Subsequently, the material box clamp transmission mechanism is started, and at this time, the connecting shaft 202 first makes a linear motion to extend to the inner side of the clamp seat 1, and the extended connecting shaft 202 drives the reversing seat 14 at its end to move synchronously. As can be seen from the figure, the reversing groove 1401 provided on the other side of the reversing seat 14 cooperates with the reversing rod 13 through the pin 1301, so that the reversing rod 13 moves upward and extends into the clamping hole 802 set in the material box 8, and the reversing rod 13 cooperates with the fixed clamp head 7 to complete the clamping action of the material box 8.

[0072] The subsequent connecting shaft 202 will synchronously drive the rotating sleeve 201 to rotate while performing linear motion. The rotation of the rotating sleeve 201 will drive the chuck seat 10 fixed thereon to rotate, so that under the cooperation of the chuck seat 10 and the fixed chuck 7, the clamped material box 8 will be flipped, so that the cooking ingredients in the material box 8 are poured into the pot, completing the flipping action.

[0073] Preferably, since the connecting shaft 202 will continue to make linear motion while rotating when flipping, in order to avoid the interference of the material box 8 on the connecting shaft 202, the reversing groove 1401 provided on the side of the reversing seat 14 is composed of two parts, namely an oblique groove and a horizontal groove. When the connecting shaft 202 makes linear motion, the pin 1301 is placed in the oblique groove and cooperates with the oblique groove to make the reversing rod 13 move in the vertical direction; when the connecting shaft 202 makes rotational motion and linear motion, the pin 1301 is placed in the horizontal groove, so that the reversing seat 14 will not drive the reversing rod 13 to move while moving.

[0074] Preferably, the fixing clamp 7 is in a T-shaped, L-shaped or trapezoidal structure. In addition, the material box 8 is provided with a slot adapted to the shape of the fixing clamp 7 .

[0075] See also Figures 13 to 18 and Figures 20 to 25In this embodiment, the movable clamp includes a chuck seat 10, a pull rod 12, two movable chucks 9 and any one of the above-mentioned material box 8 clamp transmission mechanisms; the chuck seat 10 is fixedly connected to the rotating sleeve 201, and the connecting shaft 202 extends into the chuck seat 10; the movable chuck 9 includes a guide portion 901 and a clamping portion 903, and the guide portion 901 is provided with a guide groove 902, and the pull rod 12 extends into the guide groove 902; the connecting shaft 202 can drive the pull rod 12 to move so that the movable chuck 9 is closed or unfolded around the rotating axis 1001 provided in the joint seat.

[0076] Among them, see Figures 13 to 18 In some embodiments, the pull rod 12 is disposed at the end of the connecting shaft 202 , and the movable chuck 9 is located in the front opening of the chuck seat 10 .

[0077] In this embodiment, combined with Fig.19 The structure of the material box 8, the operating principle of the movable clamp is: first, the material box conveying mechanism can be used to adjust the position of the material box 8 or the material feeding mechanism can be used to adjust the position of the clamp, so that the clamp seat 1 is aligned with the first clamping groove 801 at the rear end of the material box 8. Subsequently, the material box clamp transmission mechanism is started, and at this time, the connecting shaft 202 first makes a linear movement to shrink toward the inside of the clamp seat 1, and the shrinking connecting shaft 202 drives the pull rod 12 at its end to shrink synchronously. Since the pull rod 12 is located in the guide groove 902 of the movable clamp 9, the movement of the pull rod 12 will drive the movable clamp 9 to rotate around the rotating shaft 1001 set in the joint seat so that the clamping parts 903 of the two movable clamps 9 are closed to complete the clamping action of the material box 8.

[0078] The clamped material box 8 is then transferred to the dish pouring position through the transfer mechanism, and the material box clamp transmission mechanism is started again. At this time, the connecting shaft 202 will simultaneously drive the rotating sleeve 201 to rotate while performing linear motion. The rotation of the rotating sleeve 201 will drive the chuck seat 10 fixed thereon to rotate, so that under the cooperation of the chuck seat 10 and the movable chuck 9, the clamped material box 8 is turned over, so that the cooking ingredients in the material box 8 are poured into the pot, completing the turning action.

[0079] Furthermore, since the connecting shaft 202 will continue to make linear motion while rotating when flipping, in order to avoid interference of the movable clamp 9 with the connecting shaft 202, the guide groove 902 of the guide portion 901 of the movable clamp 9 is composed of two parts, namely, a rotation groove and a transition groove. When the connecting shaft 202 makes linear motion, the pull rod 12 is placed in the rotation groove and cooperates with the rotation groove to make the movable clamp 9 rotate around the rotation axis 1001; when the connecting shaft 202 makes rotational motion and linear motion, the pull rod 12 is placed in the transition groove, and at this time the transition groove is parallel to the connecting shaft 202, so that the pull rod 12 will not drive the movable clamp 9 to move while moving, and the movement of the movable clamp 9 stops and remains in a clamping state.

[0080] Among them, see Figures 20 to 25In some embodiments, a limit groove and a reversing seat fixedly connected to the connecting shaft are provided in the chuck seat, a reversing rod is provided in the limit groove, and a reversing groove is provided on the side of the reversing seat; a pin shaft extending into the reversing groove is provided at the lower end of the reversing rod, and the reversing seat drives the reversing rod to move in the vertical direction through the reversing groove and the pin shaft; the movable chuck is located in the upper opening of the chuck seat, and the pull rod is provided at the upper end of the reversing rod.

[0081] In this embodiment, combined with Figures 26 and 27 The material box 8 structure is formed by the reversing seat 14 and the reversing rod 13 to form an eccentric movable clamp. Its operating principle is: first, the material box conveying mechanism can be used to adjust the position of the material box 8 or the clamp position can be adjusted by the feeding mechanism, so that the clamp seat 1 is aligned with the second clamping groove 803 at the lower end of the material box 8. Subsequently, the material box clamp transmission mechanism is started, and at this time, the connecting shaft 202 first makes a linear motion to shrink to the inside of the clamp seat 1, and the shrinking connecting shaft 202 drives the reversing seat 14 at its end to move synchronously. Fig.23 It can be seen that the reversing seat 14 is an L-shaped structure, and the reversing groove 1401 provided on the other side of the reversing seat 14 cooperates with the reversing rod 13 through the pin shaft 1301, so that the reversing rod 13 moves downward. When the reversing rod 13 moves downward, it drives the upper end pull rod 12 to move. Since the pull rod 12 is located in the guide groove 902 of the movable clamp 9, the movement of the pull rod 12 will drive the movable clamp 9 to rotate around the rotating shaft 1001 provided in the joint seat so that the clamping parts 903 of the two movable clamps 9 are closed to complete the clamping action of the material box 8.

[0082] The clamped material box 8 is then transferred to the dish pouring position through the transfer mechanism, and the material box clamp transmission mechanism is started again. At this time, the connecting shaft 202 will simultaneously drive the rotating sleeve 201 to rotate while performing linear motion. The rotation of the rotating sleeve 201 will drive the chuck seat 10 fixed thereon to rotate, so that under the cooperation of the chuck seat 10 and the movable chuck 9, the clamped material box 8 is turned over, so that the cooking ingredients in the material box 8 are poured into the pot, completing the turning action.

[0083] Furthermore, since the connecting shaft 202 will continue to make linear motion while rotating during flipping, in order to avoid interference of the movable clamp 9 with the connecting shaft 202, the reversing groove 1401 provided on the side of the reversing seat 14 is composed of two parts, namely an oblique groove and a horizontal groove. When the connecting shaft 202 makes linear motion, the pin 1301 is placed in the oblique groove and cooperates with the oblique groove to make the reversing rod 13 move in the vertical direction; when the connecting shaft 202 makes rotational motion and linear motion, the pin 1301 is placed in the horizontal groove, so that the reversing seat 14 will not drive the reversing rod 13 to move while moving, and the movement of the movable clamp 9 stops and remains in a clamping state.

[0084] The three different types of material box clamps, namely the fixed clamp, the movable clamp and the eccentric clamp, can complete all operations of clamping and flipping the material box 8 with only one power element by relying on the transmission mechanism of the material box clamp, and the overall structure is simple and reliable. Compared with the existing material box clamps that need to use multiple sets of power elements to complete the clamping and flipping actions, the control method of the material box clamp of the present invention is also simpler.
