[0061] This embodiment provides a dispensing device, such as Figure 1-Figure 7As shown, the dispensing device includes a frame body 11 and a dispensing mechanism. The dispensing mechanism is connected to the frame body 11 and includes a needle assembly 21, a glue cylinder 22, and a conductor 23. The glue cylinder 22 is connected to the frame body 11 and can hold glue liquid. The needle assembly 21 is connected to the lower end of the glue cylinder 22 and is in communication with the glue cylinder 22. The lower end of the needle assembly 21 is a glue outlet. The conductor 23 is connected to the frame body 11 and is arranged around the outer periphery of the needle assembly 21. The conductor 23 is used to connect to high voltage electricity. When the dispensing device is operating, a high voltage electric field is applied between the conductor 23 and the dispensing plate supporting the component to be dispensed, and the needle assembly 21 and the dispensing plate are caused to move relative to each other. Under the action of the high voltage electric field, the glue liquid in the needle assembly 21 is deposited on the dispensing component, forming micro / nano fibers or droplets. The dispensing device is driven by the high voltage electric field to perform non-contact printing and has the characteristics of high resolution, high precision, high material compatibility, low cost, and high efficiency.

[0062] In this embodiment, Figure 1 As shown, the needle assembly 21 includes a needle 211 and a connector 212. The needle 211 is connected to the rubber cylinder 22 via the connector 212 to achieve a stable outflow of the rubber liquid. Optionally, the connector 212 is a Luer connector.

[0063] like Figure 1 As shown, the dispensing device also includes a fastening hoop 13, which includes two semicircular annular hoops, one end of the two semicircular annular hoops is respectively connected to the frame body 11, and the other ends of the two semicircular annular hoops are matched and connected. The two semicircular annular hoops surround the outer circumference of the rubber cylinder 22, and when matched and connected, the rubber cylinder 22 can be fixed on the frame body 11. When the semicircular annular hoops are opened, the lock on the rubber cylinder 22 can be released, which facilitates the disassembly and replacement of the rubber cylinder 22.

[0064] like Figure 1 As shown, the dispensing device also includes a liquid level sensor 16, which is mounted on the frame body 11 and is used to detect the level of the glue liquid within the glue cartridge 22. When the glue liquid in the glue cartridge 22 is insufficient, the liquid level sensor 16 can send a signal to the alarm component, which issues a prompt message, prompting the operator to replace the glue cartridge 22. In this embodiment, the liquid level sensor 16 is a capacitive type, which prevents the sensor from directly contacting the glue liquid. In other embodiments, the liquid level sensor 16 can also be a photoelectric type, which is not specifically limited here.

[0065] like Figure 1 As shown, the dispensing device further includes a curing lamp 15, which is disposed on the frame body 11 and is used to cure the glue liquid after dispensing. The glue liquid cures quickly after dispensing, thereby improving the working efficiency of the dispensing device.

[0066] like Figure 1-Figure 4As shown, the dispensing device also includes an observation assembly 5, which is connected to the frame body 11 and is used to capture images of the glue outlet, allowing the user to observe the glue dispensing status of the glue outlet in real time. In the prior art, the camera is directly mounted on the frame body 11. However, when the dispensing device is replaced with a needle assembly 21 of a different size, the camera may not be aligned with the glue outlet and cannot be focused. Adjusting the camera to align and focus with the glue outlet of the new needle assembly 21 is difficult.

[0067] In this regard, in this embodiment, the dispensing device also includes a first adjustment component 3, the first adjustment component 3 includes a support member 31, a first slide 32 and a second slide 33, the support member 31 is connected to the frame body 11, the first slide 32 is connected to the support member 31, and can slide or lock relative to the support member 31 along a first direction, the second slide 33 is connected to the first slide 32, and can slide or lock relative to the first slide 32 along a second direction, the observation component 5 is connected to the second slide 33, and the first direction is perpendicular to the second direction.

[0068] The dispensing device of this embodiment is provided with a first adjustment component 3 that can adjust the position of the observation component 5 observing the glue outlet along the first direction and the second direction. This ensures that after the needle assembly 21 of the dispensing device is replaced, the observation component 5 can be conveniently and flexibly adjusted to align with the glue outlet of the current needle assembly 21 and focus, thereby accurately and clearly capturing an image of the glue outlet, thereby improving the flexibility and reliability of the dispensing device. In this embodiment, the needle assembly 21 is mounted on the frame body 11.

[0069] like Figure 4 As shown, the observation component 5 includes a camera 51 and a fixing part 52. One side of the fixing part 52 is connected to the second slide 33, and the other side is connected to the camera 51. When the fixing part 52 moves with the second slide 33, it drives the camera 51 to move. The camera 51 can observe the dispensing port of the needle assembly 21 and can transmit image information to the computer, which is convenient for the operator to monitor. In this embodiment, the observation direction of the camera 51 is set at an angle to the first direction, which is convenient for observing the glue outlet of the needle assembly 21. Optionally, the angle can be 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, etc., which is not specifically limited here. It is sufficient to be able to better observe the glue outlet of the needle assembly 21.

[0070] like Figure 1-Figure 2 As shown, in order to cooperate with the specific application of the observation component 5, the dispensing device also includes a light source 17. The light source 17 is mounted on the frame body 11 and fixed relative to the frame body 11. The irradiation direction of the light source 17 is set at an angle to the first direction, and continuously irradiates the glue outlet of the needle assembly 21 to provide light support for the observation component 5, so that the observation effect of the observation component 5 is better.

[0071] like Figure 4-Figure 5As shown, the support member 31 is provided with a first groove 311 extending in the first direction, and the second slide 33 is provided with a second groove 323 extending in the second direction. The first slide 32 includes a first sliding portion 321 extending in the first direction and a second sliding portion 322 extending in the second direction. The first sliding portion 321 slidably cooperates with the first groove 311 to enable the first slide 32 to slide relative to the support member 31 in the first direction, and drives the second slide 33 to slide synchronously in the first direction relative to the support member 31, thereby adjusting the position of the observation component 5 in the first direction. The second sliding portion 322 is protruding from the side of the first sliding portion 321 facing the second slide 33 and slidably cooperates with the second groove 323 to enable the second slide 33 to slide relative to the first slide 32 in the second direction, thereby adjusting the position of the observation component 5 in the second direction. The first slide 32 is roughly a cross-shaped structure with a sophisticated structure, which facilitates the adjustment of the position of the observation component 5 in the first and second directions.

[0072] like Figure 5 As shown, the first adjustment assembly 3 further includes a first fastener 361 and a second fastener 362. The first fastener 361 is used to connect the support member 31 and the second sliding portion 322 of the first slide 32, thereby locking the first slide 32 in the first direction. The second fastener 362 is used to connect the first sliding portion 321 and the second slide 33, thereby locking the second slide 33 in the second direction. This locks the position of the observation assembly 5, ensuring stable observation of the glue outlet.

[0073] like Figure 5 As shown, the first adjustment component 3 also includes a first guide member 34 and a second guide member 35. The first guide member 34 includes a first guide sleeve portion 341 and a first guide column portion 342. The first guide sleeve portion 341 is connected to the support member 31, the first guide column portion 342 is connected to the first slide 32 and extends along the first direction, and the first guide column portion 342 slides in cooperation with the first guide sleeve portion 341. The second guide member 35 includes a second guide sleeve portion 351 and a second guide column portion 352. The second guide sleeve portion 351 is connected to the first slide 32, the second guide column portion 352 is connected to the second slide 33 and extends along the second direction, and the second guide column portion 352 slides in cooperation with the second guide sleeve portion 351. The first slide 32 slides smoothly in the first direction, and the second slide 33 slides smoothly in the second direction, so that the observation component 5 can be stably adjusted in the first and second directions. The structure of the first adjustment component 3 is ingenious, which improves the reliability of the dispensing device.

[0074] Specifically, the first guide column portion 342 is connected to the second sliding portion 322 and is disposed below the second sliding portion 322. The second guide sleeve portion 351 is connected to the first sliding portion 321 and is disposed on the side of the first sliding portion 321.

[0075] like Figure 1-Figure 4 As shown, the dispensing device also includes a second adjustment assembly 4, which is connected to the frame body 11. The first adjustment assembly 3 is connected to the second adjustment assembly 4. The second adjustment assembly 4 can rotate or lock relative to the frame body 11 around the axis of the needle assembly 21. The observation assembly 5 rotates around the axis of the needle assembly 21 and can be aligned with different positions of the glue outlet for observation, thereby flexibly selecting the desired observation position.

[0076] like Figure 1 and Figure 4 As shown, the frame body 11 is provided with an annular boss 111 surrounding the rubber cylinder 22. The upper end of the rubber cylinder 22 passes through the annular boss 111, and the axis of the annular boss 111 is collinear with the axis of the rubber cylinder 22. The second adjustment component 4 is provided with a clearance hole 42 that cooperates with the annular boss 111. The clearance hole 42 is sleeved on the annular boss 111 to enable the second adjustment component 4 to rotate around the axis of the needle assembly 21 relative to the frame body 11. In this embodiment, the second adjustment member 4 is also provided with an arc hole 43. The axis of the arc hole 43 is collinear with the axis of the annular boss 111. A fastener can pass through the arc hole 43 and connect to the frame body 11 to lock the second adjustment member 4 relative to the frame body 11.

[0077] like Figure 1 and Figure 4 As shown, to provide a reference for the operator during the rotation and adjustment of the second adjustment assembly 4, the dispensing device further includes an indicator 14. The indicator 14 is mounted on the frame body 11 and remains fixed relative to the frame body 11. Correspondingly, a scale plate 41 is provided on the second adjustment assembly 4. When the second adjustment assembly 4 rotates about the axis of the needle assembly 21, the scale plate 41 rotates, and the scale indicated by the indicator 14 on the scale plate 41 changes. The scale value on the scale plate 41 indicated by the indicator 14 when the observation effect is good is recorded to facilitate the next adjustment of the position of the observation assembly 5.

[0078] like Figure 7 and Figure 8 As shown, the frame body 11 includes an insulating shell 112, which is arranged to cover the outer periphery of the conductor 23. This effectively prevents operators from being injured by accidentally touching high voltage electricity. The conductor 23 includes a main body 231 and an end 232. The cross-sectional area of ​​the main body 231 is larger than the cross-sectional area of ​​the end 232. The main body 231 is provided with a through hole 2311, and a fastener can pass through the through hole 2311 and connect to the insulating shell 112 to fix the conductor 23. The main body 231 is also provided with a connecting hole 2312, and the connecting hole 2312 is used to connect high voltage electricity. The end 232 is provided with a threaded hole 2321, and a fastener can pass through the threaded hole 2321 to further fix the connector 212 of the needle assembly 21.

[0079] like Figure 7 and Figure 8 As shown, the dispensing device further includes a first heating element 61 and a second heating element 62. The first heating element 61 is used to heat the glue liquid in the glue cartridge 22, and the second heating element 62 is used to heat the glue liquid in the needle assembly 21. The ability to heat the glue liquid in the glue cartridge 22 and keep the glue liquid in the needle assembly 21 warm allows the dispensing device to be used with fluids of varying viscosities.

[0080] In this embodiment, the first heating element 61 is mounted on the frame body 11 and in close contact with the rubber sleeve 22. A first mounting hole 2313 is defined within the main body 231 of the conductor 23, and the second heating element 62 is at least partially disposed within the first mounting hole 2313. Due to the excellent thermal conductivity of the conductor 23, the adhesive within the needle assembly 21 is effectively heated. In other embodiments, the second heating element 62 may be positioned externally to the conductor 23, although this is not a specific limitation.

[0081] like Figure 7 As shown, the dispensing device further includes two insulating and heat-insulating members 12. The insulating and heat-insulating members 12 are disposed on the frame body 11, wherein one insulating and heat-insulating member 12 is used to isolate the first heating member 61 from the frame body 11, and the other insulating and heat-insulating member 12 is used to isolate the second heating member 62 from the frame body 11. In addition, the insulating and heat-insulating members 12 cooperate with the insulating shell 112 to more fully cover the conductor 23.

[0082] like Figure 7 and Figure 8 As shown, the dispensing device also includes a first temperature measuring component 71 and a second temperature measuring component 72. The first temperature measuring component 71 is used to measure the temperature of the glue in the glue barrel 22, and the first temperature measuring component 71 is electrically connected to the first heating component 61; the second temperature measuring component 72 is used to measure the temperature of the glue in the needle assembly 21, and the second temperature measuring component 72 is electrically connected to the second heating component 62. For glues of different viscosities and types, the temperature measuring component can monitor the glue temperature in a timely manner so as to adaptively adjust the heating power of the heating component to ensure that the glue temperature is appropriate and meet the process requirements of dispensing. A second mounting hole (not shown in the figure) is opened in the main body 231 of the conductor 23. The second temperature measuring component 72 is at least partially arranged in the second mounting hole to facilitate the detection of the temperature of the glue in the needle assembly 21.
