[0037] The present invention provides a dispensing device 100. Specifically, please refer to Figures 1 to 2 In this embodiment, the glue dispensing device 100 includes a base 1, a glue storage cylinder 2, a valve body structure 3 and a cooling structure 4. A glue guide channel 11 is formed on the base 1, and a glue outlet 12 is formed at one end of the glue guide channel 11; the glue storage cylinder 2 is arranged on the base 1, and the glue storage cylinder 2 is connected to the glue guide channel 11; the valve body structure 3 is arranged on the base 1 and is used to adjust the glue output at the glue outlet 12; the cooling structure 4 is arranged on one side of the valve body structure 3 and is used to cool the valve body structure 3.

[0038] In this embodiment, the glue storage cylinder 2 is used to store glue, and the glue storage cylinder 2 is connected to the glue guide channel 11 on the base 1, and the glue can flow into the glue guide channel 11 to flow out from the glue outlet 12; by providing a valve body structure 3, the glue output at the glue outlet 12 can be controlled by the valve body structure 3 to ensure that the glue output is within a suitable dispensing range; and the valve body structure 3 can be cooled by the cooling mechanism, and then after the valve body structure 3 has been working for a long time, the temperature on the valve body structure 3 can be effectively reduced by the cooling mechanism to ensure that the temperature at the valve body structure 3 is always maintained within a suitable temperature range, so as to ensure the accuracy of the adjustment of the valve body structure 3, so that the dispensing device 100 maintains a stable glue output and continuously ensures a better dispensing effect.

[0039] It should be noted that when the glue dispensing device 100 is operating normally, the glue storage cylinder 2 is mounted on the base 1, and the opening of the glue storage cylinder 2 is inserted into the glue guide channel 11. The opening of the glue storage cylinder 2 is located at the bottom of the glue storage cylinder 2, allowing the glue to flow into the glue guide channel 11 more effectively under the action of gravity. The valve body structure 3 is mounted on the base 1, and the glue outlet 12 is located at the bottom of the base 1. The descriptions of the orientations in this utility model are to be understood as such unless otherwise specified.

[0040] Preferably, combined Figure 2 and Figure 3As shown, the valve body structure 3 includes a shell 31, a top glue rod 32, a crimping part and an adjusting part 34. The shell 31 is arranged on the base 1; the top glue rod 32 is movably arranged on the shell 31, and at least a part of the top glue rod 32 can extend from the shell 31 to extend into the glue outlet 12. The top glue rod 32 has an axial movable stroke along the glue outlet 12. Preferably, the top glue rod 32 is extended in the up-down direction, the bottom of the top glue rod 32 extends into the glue outlet 12, and the top of the top glue rod 32 is arranged in the housing 31; the crimping piece is rotatably arranged in the housing 31 and crimped on the top glue rod 32; the adjusting piece 34 is movably arranged in the housing 31 and is in contact with the crimping piece. The adjusting piece 34 is moved by an external force to drive the crimping piece to rotate, so that the crimping piece can crimp on the top glue rod 32 to adjust the depth of the top glue rod 32 extending into the glue outlet 12. During operation, by adjusting the adjusting piece 34 and thereby driving the crimping piece to move, the top glue rod 32 moves to adjust the depth of the top glue rod 32 extending into the glue outlet 12. That is, the farther the glue ejecting rod 32 is from the glue outlet end of the glue outlet 12, the more glue is in the glue outlet 12. Therefore, when the glue is ejected from the glue outlet 12 by the glue ejecting rod 32, the more glue is ejected. On the contrary, the closer the glue ejecting rod 32 is to the glue outlet end of the glue outlet 12, the less glue is in the glue outlet 12. Therefore, when the glue is ejected from the glue outlet 12 by the glue ejecting rod 32, the less glue is ejected, thereby controlling the glue output of the glue dispensing device 100.

[0041] Further, if Figure 3 As shown in , the crimping member includes a crimping rod 33, one end of which is crimped onto the top glue rod 32. Preferably, the crimping rod 33 is crimped onto the top of the top glue rod 32, and the adjusting member 34 is crimped onto the other end of the crimping rod 33. The middle portion of the crimping rod 33 is rotatably connected to the housing 31. When the adjusting member 34 is pressed onto the crimping rod 33 by an external force, the crimping rod 33 rotates to move the top glue rod 32 toward the direction of withdrawing the glue outlet 12. The crimping rod 33 forms a crimping lever, and the adjusting member 34 is crimped onto one end of the crimping rod 33, so that the other end of the crimping rod 33 can move in the opposite direction.

[0042] It can be understood that the adjustment member 34 can be moved manually, or the adjustment member 34 can be driven by a driving device.

[0043] In one embodiment, the adjusting member 34 is configured as a telescopic rod. The adjusting member 34 is extended to press against the pressing rod 33, causing the push rod 32 to move toward the direction of being withdrawn from the glue outlet 12. The adjusting member 34 is retracted to move away from the pressing rod 33, causing the push rod 32 to move toward the direction of being inserted into the glue outlet 12. The telescopic movement of the telescopic rod can be driven by a driver so that the telescopic rod presses against the pressing rod 33, thereby adjusting the position of the push rod 32 to adjust the glue output or prevent glue from flowing out.

[0044] Preferably, the adjusting member 34 is configured as a piezoelectric ceramic member. According to the properties of the piezoelectric ceramic material, the piezoelectric ceramic has the property of spontaneous polarization, and the spontaneous polarization can be transformed under the action of an external electric field. When an external electric field identical to the spontaneous polarization is applied, it is equivalent to enhancing the polarization intensity. The increase in polarization intensity causes the piezoelectric ceramic member to stretch along the polarization direction. On the contrary, if a reverse electric field is applied, the piezoelectric ceramic member shortens along the polarization direction. The adjusting member 34 can be electrically connected to the power supply device. When the adjusting member 34 is connected to an electric field, the direction of the electric field is adjusted to deform the adjusting member 34 to achieve expansion and contraction in the up and down directions, and then the crimping action can be applied to the crimping rod 33. This makes the structure of the adjusting member 34 simpler, thereby making the internal structure of the valve body structure 3 simpler, which is beneficial to the heat dissipation of the valve body structure 3.

[0045] Moreover, the end surface of the adjusting member 34 in contact with the pressing rod 33 is arranged in an adaptive arc shape, so that the adjusting member 34 is not easy to slip when pressing the pressing rod 33, and the contact is more stable, so that the pressing of the adjusting member 34 on the pressing rod 33 is more stable, making the glue output more accurate.

[0046] like Figure 3 As shown in FIG, a limit pin 36 is further provided within the housing 31. When the adjusting member 34 presses the pressing rod 33 to a preset position, the pressing rod 33 abuts the limit pin 36. Specifically, when the adjusting member 34 presses downwardly against the pressing rod 33 and the adjusting member 34 is at its lowest position, the pressing rod 33 abuts the limit pin 36. The limit pin 36 controls the downward pressure of the adjusting member 34, thereby controlling the highest position of the glue-lifting rod 32 and achieving the maximum glue output. Of course, the specific maximum glue output can be set based on the size and requirements of the actual equipment and is not specifically limited here.

[0047] In addition, combined Figure 2 and Figure 3As shown, the valve body structure 3 also includes an elastic telescopic member 35, which is sleeved on the outside of the top glue rod 32 and respectively abuts between the shell 31 and the top glue rod 32. The elastic telescopic member 35 can be set as a telescopic spring. For example, when the adjusting member 34 is not crimping the crimping rod 33, the top glue rod 32 is in an initial position. When the adjusting member 34 is crimping the crimping rod 33, the elastic telescopic member 35 is in an extended state. When the adjusting member 34 moves upward, the pressure on the crimping rod 33 gradually decreases. The crimping rod 33 can rotate under the elastic restoring force of the elastic telescopic member 35, so that the top glue rod 32 can be restored to the initial position. The resetting of the top glue rod 32 does not require additional driving force, the operation is simpler, and the structure is also simpler.

[0048] When the adjustment member 34 is a piezoelectric ceramic, the piezoelectric ceramic will generate significant heat when energized. Therefore, in order to dissipate heat more effectively and quickly, the cooling structure 4 preferably includes a heat dissipation structure and a fan 44. The heat dissipation structure is disposed outside the housing 31 and corresponding to the adjustment member 34. The fan 44 is disposed on the side of the heat dissipation structure facing away from the housing 31. The heat dissipation structure can dissipate heat within the valve body structure 3, and the fan 44 can quickly dissipate the heat, thereby achieving effective and rapid heat dissipation and ensuring cooling of the valve body structure 3.

[0049] Further, combined with Figure 2 and Figure 4 As shown, the heat dissipation structure includes a cooling block 41, a cooling fin 42, and a semiconductor heat dissipation block 43. The cooling block 41 is arranged in contact with the shell 31, and the semiconductor heat dissipation block 43 is arranged in contact with the cooling block 41. The cooling fin 42 is arranged in a groove formed between the cooling block 41 and the semiconductor heat dissipation block 43. The fan 44 is located on the outside of the heat dissipation block. The cold side of the semiconductor heat dissipation block 43 is in contact with the cooling fin 42 and the cooling block 41, which can quickly dissipate the heat in the valve body structure 3. The heat dissipation end of the semiconductor heat dissipation block 43 is opposite to the fan 44, and the fan 44 can quickly blow away the heat on the semiconductor heat dissipation block 43. The heat dissipation efficiency is high, so as to ensure that the valve body structure 3 always remains within the appropriate working range, thereby ensuring the working stability and accuracy of the valve body structure 3, and allowing the dispensing device 100 to maintain a stable glue output.

[0050] The present invention also provides a dispensing device, which includes the above-mentioned dispensing device 100. The dispensing device 100 enables the dispensing device to achieve continuous and stable dispensing, has a longer working life, better working stability, and better dispensing effect.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
