DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] The embodiment of the present application provides an automatic quantitative liquid discharging and filling robot for coffee brewing, which solves the problem that the existing liquid discharging and filling robots are usually composed of a robotic arm, a pump group and a solenoid valve. When controlling the liquid discharge, the quantity is mainly controlled by controlling the time of the solenoid valve. During actual use, due to the inconsistency of the pressure of the pump group, the flow control is not accurate enough. In addition, the liquid discharge is carried out by relying on the solenoid valve, which may malfunction and cause large deviations in the liquid discharge volume, which cannot meet the demand.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The utility model discloses an automatic quantitative liquid dispensing and filling robot for coffee brewing. Figure 1-4 As shown, it includes a robot movable arm 1, a docking seat 3 is movably connected to the robot movable arm 1, and a quantitative unit 4 is provided on the docking seat 3;

[0025] The quantitative unit 4 includes a quantitative container 41 and an electric push rod 42 arranged on the docking seat 3. The output end of the electric push rod 42 is connected to the piston inside the quantitative container 41.

[0026] The quantitative container 41 is provided with a main delivery pipe 43, which is connected to a first one-way valve 431, and a filling nozzle 432 is provided on the first one-way valve 431. The main delivery pipe 43 is connected to a suction pipe 44, and a second one-way valve 441 is provided on the suction pipe 44; the suction pipe 44 is connected to an external container for brewing coffee.

[0027] The automatic quantitative liquid discharging and filling robot for coffee brewing uses a quantitative unit 4 to achieve quantitative filling of an external container for coffee brewing during use. The quantitative unit 4 replaces the traditional electromagnetic valve to control the discharge volume. On the one hand, quantitative measurement is performed by the quantitative container 41, ensuring more accurate quantitative measurement. On the other hand, the problem of uncontrollable discharge volume and large error caused by failure of the electromagnetic valve itself is avoided. The quantitative container 41 is placed on the movable arm 1 of the robot, which has good stability and is easy to visually observe the discharge volume.

[0028] When discharging and filling are required, the electric push rod 42 is directly used to provide power. The electric push rod 42 first drives the piston inside the quantitative container 41 to move, so that the piston generates negative pressure, and the liquid in the external container is sucked into the quantitative container 41 through the main delivery pipe 43 and the suction pipe 44. At this time, the first one-way valve 431 is in the closed state, and the second one-way valve 441 is in the open state;

[0029] After a fixed amount of liquid is sucked into the quantitative container 41 through the electric push rod 42 and the piston, the electric push rod 42 is pushed in the opposite direction and the filling nozzle 432 is aligned with the coffee brewing container, so that the piston pushes the fixed amount of liquid inside the quantitative container 41 and presses it out from the main delivery pipe 43 and the filling nozzle 432 in sequence. At this time, the first one-way valve 431 is in the open state and the second one-way valve 441 is in the closed state.

[0030] A sleeve 2 is fixedly connected to the robot's movable arm 1, and a locking column 31 is provided on the docking seat 3. The locking column 31 is movably inserted into the inside of the sleeve 2. The device makes it easy to install the docking seat 3 and the quantitative unit 4 on the robot's movable arm 1 through the clamping connection between the sleeve 2 and the locking column 31. The docking seat 3 and the quantitative unit 4 are easy to disassemble and assemble, so it is convenient to quickly replace quantitative containers 41 of various capacities, thereby making the device suitable for use in different fields.

[0031] The sleeve 2 is provided with a locking mechanism 5 for locking the position of the locking column 31. The locking mechanism 5 includes an embedding groove 51 provided on the sleeve 2 and a claw 53 movably engaged with the inside of the embedding groove 51. The locking column 31 is provided with a slot 32. The claw 53 is movably engaged with the slot 32. A rotating plate 52 for supporting the claw 53 is rotatably connected to the inside of the embedding groove 51. A spring 54 is fixedly connected between the rotating plate 52 and the inner wall of the embedding groove 51. A notch 55 corresponding to the position of the claw 53 is provided in the embedding groove 51.

[0032] The device is designed with a locking mechanism 5, which makes it easy to lock the sleeve 2 and the locking column 31;

[0033] When the sleeve 2 and the docking seat 3 need to be installed, the rotating plate 52 is first pressed, so that the rotating plate 52 drives the claw 53 to tilt up and squeeze the spring 54 at the same time. At this time, the sleeve 2 and the locking column 31 are clamped. After they are fully clamped, release the rotating plate 52, the spring 54 resets and pushes the rotating plate 52 to rotate, and the rotating plate 52 drives the claw 53 to clamp in the slot 32, so that the position of the sleeve 2 and the docking seat 3 is fixed, which is easy to operate.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
