[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 4 In the utility model, a positioning device of a manual dispensing machine includes a dispensing machine body 1 and a mounting base 2 installed on the top thereof, the top of the mounting base 2 is detachably connected to a positioning base 3, two expansion slots 4 are provided on the inner wall of the positioning base 3, a limiting component 5 is arranged inside the expansion slot 4, a mounting slot 6 is provided on the inner bottom wall of the positioning base 3, a screw rod is rotatably connected on the inner wall of the mounting slot 6, the limiting component 5 is connected to the screw rod, a driving motor 7 is fixedly installed on the inner wall of the mounting slot 6, the output shaft of the driving motor 7 is connected to the screw rod through a gear transmission, a supporting plate 8 is fixedly connected to the inner wall of the positioning base 3, the supporting plate 8 is located at the top of the mounting slot 6, a processor 9 is integrated inside the positioning base 3, and the limiting component 5 and the driving motor 7 are both connected to the processor 9 signal;

[0024] The limiting assembly 5 includes a synchronous seat 501, which is threadedly connected to the screw rod. The synchronous seat 501 is provided with evenly distributed air cavities 502. A piston seat 503 is slidably installed inside the air cavity 502. A limiting rod 504 is fixedly connected to the piston seat 503. The end of the limiting rod 504 away from the piston seat 503 passes through the air cavity 502 and extends to the outside of the synchronous seat 501. A micro air pump 505 connected to the interior of the synchronous seat 501 is fixedly installed on the synchronous seat 501, and an air pressure sensor 506 is fixedly installed on the inner wall of the synchronous seat 501.

[0025] A pressure sensor 10 is fixedly mounted on the top of the support plate 8, and the pressure sensor 10 is connected to the processor 9 for signal connection;

[0026] The bottom of the synchronous seat 501 is fixedly connected with a slider 13, which is located inside the mounting groove 6 and is threadedly connected to the screw rod. The slider 13 is slidably connected to the inner wall of the mounting groove 6; the piston seat 503 and the inner wall of the air cavity 502 are slidingly sealed.

[0027] When a dispensing machine is needed for dispensing operations, the workpiece needs to be positioned first through the positioning seat 3 on the top of the mounting seat 2. The user lifts the workpiece to the top of the positioning seat 3 and then moves the workpiece downward until the bottom of the workpiece is in contact with the top of the support plate 8. At this time, the pressure sensor 10 on the support plate 8 is triggered, and the processor 9 controls the operation of the drive motor 7 and the limit assembly 5 after receiving the signal from the pressure sensor 10. The driving motor 7 transmits the transmission to the screw rod through the gear so that the screw rod starts to rotate, and the synchronous seat 501 threadedly connected to the screw rod starts to move out from the inside of the expansion groove 4 and gradually approaches the workpiece. At this time, the micro air pump 505 in the limit assembly 5 starts to operate, and the micro air pump 505 generates suction to send external gas into the interior of the synchronous seat 501, and the air flow enters the air cavity 502. As the air pressure gradually increases, the piston seat 503 is pushed to move inside the air cavity 502, and the limit rod 504 moves accordingly to extend to the outside. When the set value is reached, the micro air pump 505 closes. At this time, the air pressure sensor 506 will record the value, and multiple sets of limit rods 504 are also fully extended. As the drive motor 7 continues to operate, the limit rod 504 extending from the synchronous seat 501 contacts the workpiece. At this time, the thrust is greater than the internal pressure of the synchronous seat 501, and the limit rod 504 moves into the air cavity 502, thereby compressing the gas and generating an opposite force. The value of the air pressure sensor 506 increases and transmits a signal to the processor 9. At this time, the processor 9 determines the clamping force of the limit rod 504 on the workpiece based on the value. Multiple groups of piston seats 503 that can slide inside the air cavity 502 can be positioned in different positions according to the surface state of the workpiece, so that multiple groups of limit rods 504 can also achieve a good positioning effect for the side profiles of the workpiece. When the value sent back by the air pressure sensor 506 reaches the set value, the processor 9 controls the drive motor 7 to stop operating. At this time, the positioning of the workpiece is completed and the subsequent dispensing operation can be carried out. After the dispensing is completed, the drive motor 7 is controlled to rotate in the opposite direction to drive the synchronous seat 501 to separate from the workpiece through the screw rod, and then the workpiece can be taken out.

[0028] In the present invention, the positioning of the workpiece is achieved by setting a positioning seat 3 on the top of the dispensing machine body 1, and the positioning process is automated through the cooperation of the sensor and the processor 9, so that the workpiece positioning is achieved conveniently and quickly, and the workpiece is positioned by the horizontal movement of the limiting component 5. The limiting rod 504 is supported by air pressure in the limiting component 5, so that efficient positioning can be achieved for workpieces of different specifications and shapes during the positioning process.

[0029] See also Figure 1 and 4 , wherein: a signal light 11 is fixedly installed on the left side of the positioning seat 3, and the signal light 11 is connected to the processor 9 signal.

[0030] In the present invention, when the positioning seat 3 performs positioning operation on the workpiece, the processor 9 will control the indicator light 11 to flash in real time. The indicator light 11 can serve as a reminder to the user so that the user can understand the equipment status in time and perform subsequent operations.

[0031] See also Figure 2 and 3 , wherein: one end of the limiting rod 504 located outside the air cavity 502 is fixedly connected to the soft pad 12, and the soft pad 12 is made of rubber material.

[0032] In the present invention, when the limiting rod 504 is close to the workpiece, the rubber cushion 12 can further increase the clamping force on the workpiece without causing significant wear on the workpiece.
