Existing dispensing devices typically lack level detection capabilities, requiring operators to constantly monitor the glue level in the cartridge. Neglecting this can lead to dispensing valve interruption, affecting subsequent dispensing operations. Furthermore, when operators replace the cartridge after it has run out of glue, a gap often exists between the old and new glue, impacting the quality and precision of subsequent dispensing. Utility Model Content

[0003] The purpose of this invention is to provide a dispensing device that can monitor the amount of glue in the glue tube, so as to avoid affecting subsequent dispensing work due to insufficient glue.

Detailed Implementation

[0023] To illustrate the technical features, objectives, and effects of this utility model in detail, the following description, in conjunction with the accompanying drawings and embodiments, provides a further detailed explanation. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0024] Please see the appendix Figure 1-3 A dispensing device includes a base 1; a dispensing valve 3, mounted on the base 1, for continuously or quantitatively dispensing adhesive; a drive source 2, connected to the dispensing valve 3 and controlling the dispensing action of the dispensing valve 3; an adhesive cartridge 4, connected to the dispensing valve 3 and inputting adhesive into the dispensing valve 3; and a liquid level monitoring module, mounted on the base 1, for monitoring the amount of adhesive in the adhesive cartridge 4.

[0025] In the above embodiments, the base 1 is used to install the dispensing device onto the dispensing equipment, and the dispensing valve 3 is used to perform the dispensing action. When used in equipment that requires continuous dispensing, such as dams, the dispensing valve 3 can be a screw valve. When used in dispensing equipment that has high requirements for dispensing volume, such as chip dispensing machines, the dispensing valve 3 can be a metering valve. The drive source 2 is used to control the dispensing action of the dispensing valve 3. The liquid level monitoring module is used to monitor the amount of glue in the glue cartridge 4 in real time. When the amount of glue in the glue cartridge 4 is lower than a certain threshold, it sends a warning signal to the dispensing equipment, so that the dispensing equipment can issue a warning in time and the operator can replace the glue cartridge 4 in time, thereby avoiding the impact of insufficient glue on subsequent dispensing work. At the same time, timely replacement of the glue cartridge 4 can also avoid the inability to continue between the old and new glue, which would cause glue breakage and affect the subsequent dispensing quality and accuracy.

[0026] Based on the above embodiments, the liquid level monitoring module includes an adapter plate 61 mounted on the base 1 and a liquid level sensor 6 mounted on the adapter plate 61. The sensing part of the liquid level sensor 6 is close to the lower end of the glue cartridge 4. For example, the adapter plate 61 is L-shaped, with its short side fixed to the base 1 and its long side extending to the outside of the glue cartridge 4 near its lower end. This makes the sensing position of the liquid level sensor 6 close to the end of the liquid level in the glue cartridge 4. When the operator hears the equipment warning signal, they can immediately begin preparing to replace the glue cartridge 4, avoiding a long waiting time that would affect the replacement efficiency of the glue cartridge 4. At the same time, the remaining glue in the glue cartridge 4 can support the dispensing work during the preparation for replacing the glue cartridge 4, avoiding glue breakage that would affect the dispensing quality and accuracy.

[0027] Based on the above embodiments, the adapter plate 61 has an oblong hole 611, and the liquid level sensor 6 is mounted on the oblong hole 611. Using the oblong hole 611 to mount the liquid level sensor 6 facilitates adjustment of the liquid level sensor 6's mounting position.

[0028] Based on the above embodiments, a vision module mounting base 11 is provided on the base 1, and a vision module 5 is mounted on the vision module mounting base 11. A lens 51 is provided at the lower end of the vision module 5. The vision module 5 identifies and positions the workpiece to be dispensed, and integrating the vision module 5 into the dispensing device can ensure the accuracy of positioning.

[0029] Based on the above embodiment, the base 1 is provided with a light source fixing seat 12, and a light source 7 is installed on the light source fixing seat 12. The light source 7 is located directly below the lens 51. Adding a light source 7 below the lens 51 can illuminate the lens 51 when acquiring images, thereby improving the imaging quality and improving the positioning accuracy.

[0030] Based on the above embodiments, the light source 7 is a coaxial light source. Using a coaxial light source enables the lens 51 to obtain images with higher contrast and clarity, further improving positioning accuracy.

[0031] Based on the above embodiments, the base 1 is provided with a positioning seat 9, the dispensing valve 3 passes through the positioning seat 9, the side of the positioning seat 9 has a glue inlet hole 92, and a glue tube connector 8 is installed on the side of the positioning seat 9. The glue tube connector 8 has a glue inlet channel 81, and the two ends of the glue inlet channel 81 are respectively connected to the glue inlet hole 92 and the glue outlet of the glue tube 4. The glue tube connector 8 connects the dispensing valve 3 and the glue tube 4, so that the glue tube 4 can be kept in a vertical state, which facilitates glue dispensing, and at the same time makes the overall structure of the dispensing device more compact.

[0032] Based on the above embodiments, one end of the glue tube connector 8 is provided with a positioning platform 83, and the positioning seat 9 has a positioning groove 91 that matches the size of the positioning platform 83. The glue inlet hole 92 is opened in the positioning groove 91, and the glue tube connector 8 has a mounting hole 82 that extends through to the positioning platform 83. A threaded hole 93 is opened in the positioning groove 91 at a position corresponding to the mounting hole 82. The mounting hole 82 and the threaded hole 93 are used to fix the glue tube connector 8 on the positioning seat 9, and the positioning groove 91 is used to position the positioning platform 83 to improve installation efficiency and provide support for the side of the positioning platform 83.

[0033] Based on the above embodiments, the glue cartridge connector 8 is connected to the glue cartridge 4 via a Luer connector 84. Using the Luer connector 84 ensures that the glue inlet channel 81 remains closed during glue cartridge 4 replacement, preventing air from entering the glue inlet channel 81 and causing the glue to solidify, thus affecting the dispensing quality and accuracy.

[0034] Based on the above embodiments, a first needle connector 32 is installed at the lower end of the dispensing valve 3. The first needle connector 32 is a hollow structure and its inner cavity is connected to the inner cavity of the dispensing valve 3. The lower end of the first needle connector 32 is provided with a tapered limiting end 321. A second needle connector 33 is installed at the lower end of the first needle connector 32. A space is formed between the inner cavity of the second needle connector 33 and the outer surface of the limiting end 321 to accommodate the wall thickness of the dispensing needle (not shown in the figure). The first needle connector 32 is fixed at the lower end of the dispensing valve 3 by a fixing sleeve 31. The limiting end 321 is tapered, allowing its outer wall to fully fit against the inner wall of the dispensing needle to increase sealing. The second needle connector 33 further limits the outer wall of the dispensing needle, improving the stability and sealing of the dispensing needle installation. For example, the second needle connector 33 has a groove 331 for limiting the flange of the dispensing needle, further improving the installation stability of the dispensing needle and preventing it from falling off. The fixing sleeve 31 and the dispensing valve 3, as well as the first needle connector 32 and the second needle connector 33, can be connected by internal and external threads to improve installation efficiency and reduce installation space.
