[0008] When this technology is used, the controller starts the reduction motor, the reduction motor drives the bidirectional screw to rotate, and the bidirectional screw drives the two threaded sleeves to move closer to each other under the action of the thread transmission force. The connecting bar causes the positioning side bar to move right, the positioning side bar moves right along the upper inclined surface of the positioning sleeve, and the other positioning side bar moves left.

[0009] Preferably, the top positioning precision conveying assembly includes a sliding sleeve frame fixedly arranged on one side of the inclined bracket; the inner wall of the sliding sleeve frame is rotatably connected with a connecting screw, and one end of the sliding sleeve frame is fixedly installed with a driving motor, the driving motor is used to drive the connecting screw to rotate, the outer wall of the connecting screw is threadedly connected with a sleeve recess, and the sleeve recess is slidably connected to the sliding sleeve frame.

[0015] 1. The present invention positions and delivers components through transverse intervals. The controller starts the reduction motor, which drives the bidirectional screw to rotate. The bidirectional screw drives the two threaded sleeves to approach each other under the action of the thread transmission force. The threaded sleeve drives the connecting strip to move right. The connecting strip causes the positioning side strip to move right. The positioning side strip moves right along the upper inclined surface of the positioning sleeve, while the other positioning side strip moves left.

When the distance value sensed by the vertical distance sensor is the same as the distance value set by the controller, the driving motor is turned off by the controller, and the top of the care liquid pump head can be accurately positioned and conveyed according to the specified distance, thereby avoiding the deviation of the conveying center of gravity of the care liquid pump head and greatly improving the stability of the care liquid pump head delivery.

[0017] 3. The present invention uses a positioning guide mechanism. When the positioning side bar moves to the right, it will drive the sliding sleeve to move to the right, and the other positioning side bar will drive the other sliding sleeve to move to the left. The sliding sleeve will be guided to move to the right along the inner wall of the guide frame. In this way, both sliding sleeves can realize guided sliding operations along the inner wall of the guide frame. When the distance value sensed by the lateral distance sensor is the same as the distance set by the controller, the reduction motor is turned off by the controller, thereby increasing the use stability of the guide sleeve, avoiding the deviation of the delivery center of gravity of the care liquid pump head, and greatly improving the delivery stability of the care liquid pump head.

[0018] The above-mentioned multiple functions interact with each other. First, the two positioning side strips can accurately position and transport the two sides of the care liquid pump head at a specified distance. Secondly, the hinge block drives the top positioning strip to move down and squeeze, and the top positioning strip accurately positions and transports the top of the care liquid pump head. Then, when the distance value sensed by the lateral distance sensor is the same as the distance set by the controller, the reduction motor is turned off by the controller to increase the stability of the guide sleeve. In summary, the two sides of the care liquid pump head can be accurately positioned and transported at a specified distance, and the top of the care liquid pump head can be accurately positioned and transported at a specified distance, avoiding the deviation of the center of gravity of the care liquid pump head and greatly improving the stability of the care liquid pump head.

[0038] The working principle of the gravity center-stabilized lifting, positioning and conveying device for the care liquid pump head of the present invention is as follows:

[0039] Step 1: When transporting in horizontal interval positioning, two support base frames 12 are supported by the support concave plate 13, the support base frame 12 supports the inclined bracket 1, and the inclined bracket 1 supports the sleeve frame 2, thereby increasing the high stability of the sleeve frame 2 when in use. At the same time, the controller 14 starts the reduction motor 4, the reduction motor 4 drives the bidirectional screw 3 to rotate, and the bidirectional screw 3 drives the two threaded sleeve blocks 5 to approach each other under the action of the thread transmission force. The threaded sleeve block 5 moves right along the inner wall of the sleeve frame 2, and the threaded sleeve block 5 drives the connecting bar 6 to move right, the connecting bar 6 causes the positioning side bar 7 to move right, and the positioning side bar 7 moves right along the upper inclined surface of the positioning sleeve 10, while the other positioning side bar 7 moves left.

[0040] Step 2: When the top is positioned and precisely conveyed, the controller 14 starts the driving motor 19 at the same time. The driving motor 19 drives the connecting screw 18 to rotate. The connecting screw 18 drives the sleeve concave block 20 to move right under the action of the thread transmission force. The sleeve concave block 20 drives the push rod 21 to move right. The push rod 21 drives the top of the sleeve rod 22 to move right, and the sleeve rod 22 drives the linkage shaft 23 to move downward. At the same time, the linkage shaft 23 drives the hinge block 24 to move downward, and the hinge block 24 drives the top positioning bar 25 to move downward and squeeze, and the top positioning bar 25 drives the guide rod 26 to move downward, and the guide rod 26 slides down along the inner wall of the sleeve slider 27. At the same time, the vertical distance sensor 28 realizes distance sensing of the top positioning bar 25. When the distance value sensed by the vertical distance sensor 28 is the same as the distance value set by the controller 14, the driving motor 19 is turned off by the controller 14.

[0041] Step 3, during positioning and guiding, when the positioning side bar 7 moves to the right, it will drive the sliding sleeve 30 to move to the right, and the other positioning side bar 7 will drive the other sliding sleeve 30 to move to the left, and the sliding sleeve 30 drives the lateral distance sensor 31 to move to the right, and the sliding sleeve 30 slides along the outer wall of the slide bar 32, and the sliding sleeve 30 moves to the right along the inner wall of the guide frame 29, so that both sliding sleeves 30 can realize the guided sliding operation along the inner wall of the guide frame 29. The distance of the sensing block 33 is sensed by the lateral distance sensor 31. When the distance value sensed by the lateral distance sensor 31 is the same as the distance set by the controller 14, the reduction motor 4 is turned off by the controller 14.

[0042] Step 4, during lifting and conveying, insert the care liquid pump head into the pump head positioning hole 11 inside the positioning sleeve 10, and realize the positioning operation of the care liquid pump head through the pump head positioning hole 11. At the same time, the care liquid pump head can realize the positioning and conveying on both sides through the two positioning side strips 7, and the tilting bracket 1 supports the transmission motor 16, and the controller 14 starts the transmission motor 16, and the transmission motor 16 drives the belt roller 15 to transmit, and the belt roller 15 drives the conveying belt 8 to realize the transmission and conveying operation, so that the conveying belt 8 drives the two limiting strips 9 to transmit, and the limiting strip 9 drives the positioning sleeve 10 to tilt upward, and the positioning sleeve 10 drives the care liquid pump head to tilt upward, so that the care liquid pump head can be accurately positioned and conveyed along the two positioning side strips 7, and the top of the care liquid pump head can be guided and tilted upward along the lower clear surface of the top positioning strip 25, and the lifting and conveying of the care liquid pump head is more stable.
