[0024] Such as Figures 1 to 4As shown in the figure, a dispensing device with controllable dispensing volume includes a support platform 1. A two-dimensional moving platform 2 is fixedly installed on the top surface of the support platform 1. A telescopic support frame 3 is slidably connected to the surface of the two-dimensional moving platform 2. A glue feeding component 4 for supplying glue is arranged on the surface of the telescopic support frame 3. A switching component 6 is fixedly connected to the surface of the telescopic support frame 3. A plurality of dispensing head bodies 5 with different specifications are slidably connected to the surface of the switching component 6. A docking component 8 for connecting the dispensing head body 5 and the glue feeding component 4 is arranged on the surface of the switching component 6. More specifically, place the product to be dispensed on the surface of the support platform 1. The glue feeding component 4 and the dispensing head body 5 can quantitatively output glue. Then, use the two-dimensional moving platform 2 to control the movement of the telescopic support frame 3 and the dispensing head body 5, and the product can be dispensed. When different specifications of the dispensing head body 5 are needed, the docking component 8 can be used to release the limit on the dispensing head body 5, reset the dispensing head body 5 into the switching component 6, select a suitable specification of the dispensing head body 5 from the switching component 6 and slide it below the glue feeding component 4, and the docking component 8 can be used to quickly install and fix the new dispensing head body 5, thus completing the replacement.

[0025] The glue feeding component 4 includes a glue inlet pipe 401, and one end of the glue inlet pipe 401 is connected to a glue storage container. The other end of the glue inlet pipe 401 is fixedly connected to a connection seat 402, and the connection seat 402 is fixedly connected to the telescopic support frame 3. A metering valve 403 is arranged on the surface of the connection seat 402. It should be noted that the glue stored in the container can be exported through the glue inlet pipe 401 and sent into the interior of the connection seat 402. Glue can be dispensed through the dispensing head body 5. The metering valve 403 can control the amount of glue flowing out of the connection seat 402, thereby realizing the control of the dispensing volume.

[0026] The switching component 6 includes a storage rack 601, and the storage rack 601 is fixedly connected to the telescopic support frame 3. A sliding rack 602 is fixedly connected to the front side of the storage rack 601. A positioning rack 603 is fixedly connected to the front side of the sliding rack 602. The height of the storage rack 601 is greater than the height of the positioning rack 603, and the sliding rack 602 is inclined. The switching component 6 further includes a partition component 7 for blocking the storage rack 601 and the sliding rack 602. More specifically, different specifications of the dispensing head bodies 5 to be used are stored in the storage rack 601. When a certain specification of the dispensing head body 5 is needed, the blocking effect of the partition component 7 is removed, and the appropriate dispensing head body 5 is sent into the sliding rack 602, slides along the inner wall of the sliding rack 602 into the positioning rack 603, and finally slides to the leftmost end of the positioning rack 603, so that the dispensing head body 5 is aligned with the connection seat 402. Due to the height difference between the storage rack 601 and the positioning rack 603, the dispensing head bodies 5 stored in the storage rack 601 are prevented from affecting the dispensing process.

[0027] The partition component 7 includes an insertion shaft 701, and the insertion shaft 701 is movably inserted into the storage rack 601. One end of the insertion shaft 701 is fixedly connected with a dial block 702, and a spring 703 is fixedly connected between the dial block 702 and the storage rack 601. It should be noted that by pulling the dial block 702, the spring 703 is stretched, thereby driving the movement of the insertion shaft 701, so that the insertion shaft 701 releases the enclosure of the storage rack 601, and the dispensing head body 5 of the appropriate specification can be slid into the sliding rack 602. Under normal conditions, the insertion shaft 701 is used to block the storage rack 601 to prevent the dispensing head body 5 from sliding into the sliding rack 602 by itself.

[0028] The docking component 8 includes a threaded column 801, and the threaded column 801 is rotatably connected to the storage rack 601. The top end of the threaded column 801 is fixedly connected with a knob 802. An insertion rod 803 is threadedly connected to the surface of the threaded column 801. A positioning hole 804 is opened on the surface of the dispensing head body 5, and the end of the insertion rod 803 is movably inserted into the inner wall of the positioning hole 804. More specifically, when the dispensing head body 5 moves to the end of the positioning rack 603, the dispensing head body 5 is exactly located directly below the connecting seat 402, and the end of the insertion rod 803 will be inserted into the inner wall of the positioning hole 804. At this time, by rotating the knob 802, the threaded column 801 is driven to rotate, and under the action of the thread, the insertion rod 803 and the dispensing head body 5 can be driven to move upward, so that the dispensing head body 5 and the connecting seat 402 are tightly connected. By rotating the knob 802 in the reverse direction, the dispensing head body 5 can be controlled to move downward and disengage from the bottom end of the connecting seat 402, thus completing the disassembly.

[0029] An upper positioning plate 9 and a lower retaining ring 10 are fixedly sleeved on the surface of the dispensing head body 5. The upper positioning plate 9 is slidably connected to the switching component 6. There is a gap between the top surface of the lower retaining ring 10 and the switching component 6. The positioning hole 804 is opened on the surface of the upper positioning plate 9. It should be noted that by providing the upper positioning plate 9 and the lower retaining ring 10, the dispensing head body 5 is limited, so that the dispensing head body 5 can slide along the surface of the switching component 6 without detachment. By providing a gap between the lower retaining ring 10 and the switching component 6, the dispensing head body 5 has a rising space, avoiding the lower retaining ring 10 from obstructing the upward movement of the dispensing head body 5.

[0030] In summary: Place the product to be dispensed with glue on the surface of the support table 1. The glue feeding assembly 4 and the glue dispensing head body 5 can output glue quantitatively. Then, use the two-dimensional moving platform 2 to control the telescopic support frame 3 and the glue dispensing head body 5 to move, and the product can be dispensed with glue. When it is necessary to use glue dispensing head bodies 5 of different specifications, the docking assembly 8 can be used to release the limit on the glue dispensing head body 5, reset the glue dispensing head body 5 to the inside of the switching assembly 6, select a glue dispensing head body 5 of a suitable specification from the switching assembly 6 and slide it under the glue feeding assembly 4, and the docking assembly 8 can be used to quickly install and fix the new glue dispensing head body 5, thus completing the replacement. The effect of facilitating the quick replacement of the glue dispensing head of the glue dispensing device is achieved during use, so as to better meet the glue dispensing requirements for different adhesives, and the process of finding and taking the glue dispensing head is more convenient, faster, and more convenient to use.
