[0003] When the glue pump is pumping glue, it injects a fixed amount of glue at one time. Since the panels that need to be glued have different areas, the amount of water used each time is different. Sometimes there is not enough glue, and sometimes there is excess glue, making it impossible to quantitatively dispense glue. Utility Model Content

[0014] like Figure 1-3 The automatic dispensing machine with adaptive function shown in the figure includes a body 1 and a distance measuring assembly mounted on the body 1. The body 1 includes a movable platform 2 and a gantry 3. The movable platform 2 is mounted at the bottom of the body 1. The gantry 3 is mounted above the movable platform 2. A movable block 4 is movably mounted on the gantry 3. The distance measuring assembly is mounted on the outer wall of the movable block 4. The distance measuring assembly includes a cylinder 5, a fixed tube 6, a rotating wheel 12, and an encoder 13. The cylinder 5 is fixedly mounted on the outer wall of the movable block 4, with the output end of the cylinder 5 facing the movable platform 2. A telescopic rod 7 is movably mounted at the bottom of the fixed tube 6. A rotating wheel 12 is movably mounted at the bottom of the telescopic rod 7. An encoder 13 is mounted on the outside of the rotating wheel 12, and the rotating wheel 12 is transmission-connected to the output end of the encoder 13. A guide plate 8 is fixedly mounted on the outer wall of the movable block 4. The guide plate 8 is mounted below the cylinder 5. The output end of the cylinder 5 is fixedly connected to the fixed tube 6 via a connecting plate, one end of which is in contact with the guide plate 8.

[0015] A slot 9 is defined on the outer wall of the fixed tube 6. The top of the telescopic rod 7 is embedded within the fixed tube 6. A slider is fixedly mounted on the outer wall of the top of the telescopic rod 7, which is embedded within the slot 9. A spring 10 is fixedly mounted between the top of the telescopic rod 7 and the top of the inner wall of the fixed tube 6. A motor 11 is fixedly mounted on the bottom of the telescopic rod 7. A protective housing is sleeved over the outer wall of the rotating wheel 12. The output end of the motor 11 is fixedly connected to the top outer wall of the protective housing. An encoder 13 is fixedly mounted on the outer wall of the protective housing. The output end of the encoder 13 passes through the protective housing and is fixedly connected to the axis of the rotating wheel 12. The rotating wheel 12 is connected to the outer wall of the protective housing on the side where the encoder 13 is not mounted via a bearing.

[0016] Example: The panel to be glued is fixed to the movable platform 2. Before the glue is applied to the machine body 1 using the glue injection hose, the movable block 4 will first move horizontally on the gantry 3. Initially, the output end of the cylinder 5 is in a retracted state. After the panel is fixed, the cylinder 5 is activated, lowering the wheel 12 to a certain height. The outer wall of the guide plate 8 is provided with a groove, which adapts to the end of the connecting plate between the cylinder 5 and the fixed tube 6, providing stability for the operation of the cylinder 5 output end. The bottom edge of the rotating wheel 12 is lower than the panel, and then the moving block 4 is started, driving the cylinder 5 to move, and the cylinder 5 drives the fixed tube 6 to move, and the fixed tube 6 drives the telescopic rod 7 to move, and the telescopic rod 7 drives the rotating wheel 12 to move. After the rotating wheel 12 contacts the edge of the panel, the rotating wheel 12 moves to the outer wall above the panel, and the slider at the top of the telescopic rod 7 slides upward in the slide groove 9. The spring 10 is compressed and deformed. At the same time, the spring 10 exerts a reaction force on the telescopic rod 7, so that the outer wall of the bottom end of the rotating wheel 12 fits the panel. As the moving block 4 moves at a uniform speed, the rotating wheel 12 continues to rotate at a uniform speed due to friction with the surface of the panel. The rotation of the rotating wheel 12 drives the output end of the encoder 13 to rotate. At this time, the encoder 13 will record the number of rotations of the rotating wheel 12 until the rotating wheel 12 is separated from the panel. The length of the panel can be calculated based on the recorded number of rotations and the circumference of the rotating wheel 12. When measuring the width of the panel, the motor 11 drives the protective shell outside the rotating wheel 12 and the rotating wheel 12 to rotate ninety degrees together. The moving block 4 drives the rotating wheel 12 to the center line position of the panel. Then the moving platform 2 drives the panel to move, so that the rotating wheel 12 slides on the center line of the panel. The width of the panel is calculated by the number of rotations.

[0017] After obtaining the approximate length and width data of the panel at the control end of the machine body 1, the area can be calculated. After the area calculation is completed, the glue is quantitatively delivered according to the area of ​​the panel to reduce glue waste.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
