[0068] In order to more clearly understand the purpose, features and advantages of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless there is a conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. The embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0069] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0072] An embodiment of the present invention provides a glue filling device, which includes a glue filling mechanism, a glue discharge component and a driving component. The glue filling device is used for glue filling in a vacuum environment to fill the glue onto a product. The product can be a transformer, a relay, a power supply, a motor coil, a motor stator and rotor, etc. It can reduce the pressure loss during the flow of the glue and reduce the length of the glue filling channel to avoid the glue in the glue filling channel being affected by the external pressure and temperature, thereby accurately controlling the glue discharge amount of the glue to improve the glue filling accuracy.

[0073] Specifically, the glue filling mechanism includes: a glue filling component for accommodating the glue, the glue filling component is provided with a first glue outlet; a stopper, provided with a stop portion and a glue passage, the stop portion and the glue passage are spaced apart, the stopper is connected to the glue filling component, and the glue passage is connected to the first glue outlet; a glue outlet component, provided with a glue outlet channel and a second glue outlet, the stopper is movably provided in the glue outlet channel, and the glue outlet channel is respectively connected to the glue passage and the second glue outlet; and a driving component, connected to the glue filling mechanism, used to drive the glue filling mechanism to move relative to the glue outlet component, the stopper can move toward a direction close to the second glue outlet so that the stopper is pressed against the second glue outlet to block the second glue outlet, or can move toward a direction away from the second glue outlet so that the glue flows out from the second glue outlet.

[0074] When the above-mentioned glue filling device is filling glue, the driving part drives the glue filling mechanism to move in a direction away from the second glue outlet, so that the stop part disengages from the second glue outlet to cancel the blockage of the second glue outlet, and the glue in the glue filling assembly flows from the first glue outlet to the glue passing channel, and flows from the glue passing channel to the glue outlet channel, and the glue is discharged from the second glue outlet; after the glue filling is completed, the driving part drives the glue filling mechanism to move in a direction close to the second glue outlet, so that the stop part presses against the second glue outlet to block the second glue outlet, and the glue stops discharging from the second glue outlet.

[0075] The above-mentioned glue filling device achieves the effect that the glue can pass through the inside of the stopper by arranging a glue passage on the stopper. In this way, the stopper is connected to the bottom of the glue filling component, so that the glue in the glue filling component flows out from the first glue outlet and directly enters the glue passage of the stopper without passing through a bent channel, thereby reducing the pressure loss during the flow of the glue. At the same time, since the stopper is directly arranged under the glue filling component, the length of the glue flow channel can also be reduced, thereby reducing the amount of glue in the glue flow channel. When the external pressure and temperature change, since there is less glue in the glue flow channel, the change caused by the external influence is also smaller, so that the difference between the glue output amount of the glue filling component and the actual glue filling amount is smaller, which is convenient for precise control of the glue amount and improves the glue filling accuracy.

[0076] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0077] See also Figure 1 In some embodiments, the glue dispensing device 100 includes a glue dispensing mechanism 10, a glue dispensing assembly 20, and a driving member 30. Figure 2 The glue filling mechanism 10 includes a glue filling component 11 and a stopper 12. The glue filling component 11 is used to accommodate the glue. Figure 3 The glue filling assembly 11 is provided with a first glue outlet 111. The stopper 12 is provided with a stopper portion 121 and a glue passage 122. The stopper portion 121 and the glue passage 122 are spaced apart. The stopper 12 is connected to the glue filling assembly 11, and the glue passage 122 is connected to the first glue outlet 111. The glue discharge assembly 20 is provided with a glue discharge passage 21 and a second glue outlet 22. The stopper 12 is movably provided in the glue discharge passage 21, and the glue discharge passage 21 is respectively connected to the glue passage 122 and the second glue outlet 22. The driving member 30 is connected to the glue filling mechanism 10 and is used to drive the glue filling mechanism 10 to move relative to the glue discharge assembly 20. The stopper 12 can move toward the direction close to the second glue outlet 22 so that the stopper portion 121 presses against the second glue outlet 22 to block the second glue outlet 22, or can move toward the direction away from the second glue outlet 22 so that the glue flows out from the second glue outlet 22.

[0078] The operation process of the glue filling device 100 is roughly as follows:

[0079] When the glue filling device 100 is filling glue, the driving member 30 drives the glue filling mechanism 10 to move in a direction away from the second glue outlet 22, so that the stopper 121 is disengaged from the second glue outlet 22, so that the stopper 12 cancels the blocking of the second glue outlet 22 and forms a certain glue discharge gap, and the glue contained in the glue filling component 11 flows directly from the first glue outlet 111 to the glue feeding channel 122, and flows from the glue feeding channel 122 to the glue discharge channel 21, and the glue is discharged from the second glue outlet 22; after the glue filling is completed, the driving member 30 drives the glue filling mechanism 10 to move in a direction close to the second glue outlet 22, so that the stopper 121 is pressed against the second glue outlet 22, so that the stopper 121 blocks the second glue outlet 22, and the glue stops discharging from the second glue outlet 22.

[0080] The above-mentioned glue filling device 100 achieves the effect that the glue can pass through the inside of the stopper 12 by setting a glue passage 122 on the stopper 12. In this way, the stopper 12 is connected to the bottom of the glue filling component 11, so that the glue in the glue filling component 11 flows out from the first glue outlet 111 and directly enters the glue passage 122 of the stopper 12 without passing through a bent channel, thereby reducing the pressure loss during the flow of the glue. At the same time, since the stopper 12 is directly set below the glue filling component 11, the length of the glue flow channel can also be reduced, thereby reducing the amount of glue in the glue flow channel. When the external pressure and temperature change, since there is less glue in the glue flow channel, the change caused by the external influence is also smaller, so that the difference between the glue output amount of the glue filling component 11 and the actual glue filling amount is smaller, which is convenient for precise control of the glue amount and improves the glue filling accuracy.

[0081] See also Figure 2 In some embodiments, the glue potting assembly 11 includes a glue potting component 112, a glue injection component 113, and a conveying component 114. The glue potting component 112 is connected to the driving component 30 and the stopper 12 respectively. Figure 3 The glue filling component 112 is provided with a glue filling channel 1121 and a first glue outlet 111. The glue injection component 113 is in communication with the glue filling channel 1121 of the glue filling component 112 to allow the glue to be injected into the glue filling component 112. The conveying component 114 is at least partially disposed in the glue filling channel 1121 and is used to convey the glue in the glue filling channel 1121 to the first glue outlet 111.

[0082] In this way, by setting the glue injection part 113 to be connected to the glue filling channel 1121 of the glue filling part 112, the glue filling channel 1121 is continuously replenished with glue through the glue injection part 113, so that the glue filling device 100 can continue the glue filling operation, thereby improving the glue filling stability; by the conveying part 114 being at least partially arranged in the glue filling channel 1121, the colloid in the glue filling channel 1121 can be quickly conveyed to the first glue outlet 111, thereby improving the glue filling efficiency. In application, the glue injection part 113 can be a glue filling joint, which is connected to an external glue storage device, and the colloid in the glue storage device enters the glue filling channel 1121 through the glue injection part 113. Of course, it can also be a glue storage structure, in which colloid is stored, which is directly connected to the glue filling channel 1121, and the colloid is conveyed to the glue filling channel 1121.

[0083] It is understandable that the length of the conveying member 114 in the glue pouring channel 1121 can be adjusted according to the conveying requirements of the glue, so that the conveying member 114 can contact the glue in the glue pouring channel 1121 and convey the glue in the glue pouring channel 1121 to the first glue outlet 111.

[0084] See also Figure 4 In some embodiments, the glue filling channel 1121 of the glue filling component 112 includes a connected accommodating portion 1121a and a channel portion 1121b, the cross-sectional area of ​​the accommodating portion 1121a is larger than the cross-sectional area of ​​the channel portion 1121b, the accommodating portion 1121a is connected to the glue injection component 113, and the conveying component 114 is arranged in the accommodating portion 1121a, and the channel portion 1121b is connected to the glue passing channel 122 of the stopper 12.

[0085] In this way, since the conveying member 114 needs to be at least partially arranged in the glue pouring channel 1121, by setting the cross-sectional area of ​​the accommodating portion 1121a to be larger than the cross-sectional area of ​​the channel portion 1121b, the accommodating portion 1121a can stably accommodate the conveying member 114, and the channel portion 1121b is only used to transport the colloid, so it does not need to be set with a larger cross-sectional area. Moreover, the cross-sectional area of ​​the channel portion 1121b is smaller, and the colloid that can be accommodated in the channel portion 1121b is also less, thereby being able to further reduce the influence of external air pressure and temperature on the colloid.

[0086] In some embodiments, the glue filling component 112 further includes a detection channel 1124, which is in communication with the channel portion 1121b. The glue filling device 100 further includes a pressure sensor 40, which is connected to the glue filling component 112 and partially disposed in the detection channel 1124 to detect the pressure of the glue in the detection channel 1124. In this embodiment, the pressure sensor 40 may be a hydraulic pressure sensor.

[0087] In this way, by setting the detection channel 1124 to be connected with the channel part 1121b, part of the colloid in the channel part 1121b can flow into the detection channel 1124, so that the pressure sensor 40 can detect the pressure of the colloid in the detection channel 1124. The operator adjusts the pressure of the conveying member 114 according to the detection information obtained by the pressure sensor 40, thereby accurately controlling the glue output of the glue filling device 100 to reach the preset standard, thereby improving the glue filling accuracy. In this solution, the detection channel 1124 is configured to be connected to the channel portion 1121b. On the one hand, it can detect the pressure of the colloid conveyed from the accommodating portion 1121a by the conveying member 114. On the other hand, the function of the channel portion 1121b is to be connected to the detection channel 1124 and the glue passage 122 of the stop member 12. Therefore, when setting the detection channel 1124, it is only necessary to meet the above two requirements, so that the designed length of the detection channel 1124 can be short enough, so that the position where the pressure sensor 40 is set is closer to the second glue outlet 22, and the pressure measured by the pressure sensor 40 is closer to the actual pressure, so that the glue output amount can be more accurately controlled.

[0088] See also Figure 2 In some embodiments, the glue potting component 112 includes a first glue potting portion 1122 and a second glue potting portion 1123. The first glue potting portion 1122 and the second glue potting portion 1123 are detachably connected. The first glue potting portion 1122 is connected to the glue injection component 113, and the second glue potting portion 1123 is connected to the stopper 12. To ensure the sealing of the accommodating portion 1121a, grooves constituting the accommodating portion 1121a are provided on the first glue potting portion 1122 and the second glue potting portion 1123. After assembly, the junction of the first glue potting portion 1122 and the second glue potting portion 1123 is located in the middle of the accommodating portion 1121a, facilitating sealing of the gap. At the same time, to further ensure the sealing of the accommodating portion 1121a, a cylindrical bushing can be provided in the accommodating portion 1121a, and the conveying member 114 is provided in the hole in the middle of the cylindrical bushing. The detection channel 1124 is provided on the second glue potting portion 1123. In this embodiment, considering that the cross-sectional area of ​​the glue potting channel 1121 on the glue potting member 112 varies, the glue potting member 112 is provided as a split structure to facilitate the processing and production of the glue potting member 112. It is understood that the glue potting member 112 can also be an integrally molded structure, which provides better sealing performance.

[0089] See also Figure 3 In some embodiments, the conveying member 114 includes a conveying drive unit 1141 and a conveying unit 1142. The conveying drive unit 1141 is connected to the glue pouring member 112, and the conveying unit 1142 is connected to the conveying drive unit 1141 and is rotatably disposed in the glue pouring channel 1121. In this embodiment, the conveying drive unit 1141 can be a rotary motor, and the conveying unit 1142 can be a screw.

[0090] In this way, by rotatably positioning the conveying portion 1142 within the glue dispensing passage 1121, the conveying portion 1142 can be driven by the conveying drive portion 1141 to rapidly rotate and generate a pressing force, thereby rapidly conveying the glue to the first glue outlet 111 under the drive of the conveying portion 1142, thereby improving glue dispensing efficiency. Furthermore, the speed of the conveying drive portion 1141 can be adjusted as needed to adjust the glue dispensing pressure.

[0091] See also Figure 2 In some embodiments, the glue potting assembly 11 further includes a first connecting member 115 , which is sleeved on the outside of the glue potting member 112 and the stopper 12 to connect the glue potting member 112 and the stopper 12 .

[0092] In this way, the first connecting member 115, which is sleeved on the outside of the glue filling member 112 and the stopper 12, defines the position of the glue filling member 112 and the stopper 12, and can stably connect the glue filling member 112 to the stopper 12 within the first connecting member 115, thereby preventing positional deviation or separation between the glue filling member 112 and the stopper 12. This ensures that the glue filling channel 1121 is accurately connected to the glue feeding channel 122, allowing the glue to be stably transported from the glue filling channel 1121 to the glue feeding channel 122, preventing the glue from overflowing from the connection between the glue filling member 112 and the stopper 12, and improving the glue filling stability. In this embodiment, the first connecting member 115 is threadedly connected to the glue filling member 112, thereby facilitating the assembly and disassembly of the glue filling assembly 11.

[0093] See also Figure 4 In some embodiments, the glue pouring mechanism 10 further includes a first sealing member 13 , which is disposed between the stopper 12 and the glue pouring member 112 .

[0094] In this way, by arranging the first sealing member 13 between the stop member 12 and the glue pouring member 112, a sealing structure can be formed between the stop member 12 and the glue pouring member 112, thereby preventing the glue from overflowing from the connection between the stop member 12 and the glue pouring member 112, so that the glue can be stably transported from the glue pouring channel 1121 to the glue passing channel 122, thereby improving the glue pouring stability.

[0095] Please refer again Figure 2 In some embodiments, the driving member 30 includes a support portion 31 and a driving portion 32. The support portion 31 is connected to the glue outlet assembly 20. The driving portion 32 is disposed on the support portion 31 and connected to the glue filling member 112, and is configured to drive the glue filling member 112 to move relative to the glue outlet assembly 20, thereby driving the stopper 12 to move toward or away from the second glue outlet 22.

[0096] In this way, by providing the support portion 31 connected to the glue outlet assembly 20, and the driving portion 32 located on the support portion 31 and the glue filling member 112, the relative position of the glue filling member 112 and the glue outlet assembly 20 is stabilized, thereby enabling the driving portion 32 to stably drive the glue filling member 112 to move relative to the glue outlet assembly 20, preventing the driving portion 32 from shaking when driving the glue filling member 112 to move, and allowing the stopper 12 to stably move toward or away from the second glue outlet 22, thereby preventing the stopper 12 from colliding with other components, thereby improving the glue filling stability. At the same time, during use, if the glue filling position changes, when moving the glue filling device 100, an external power can be used to drive the glue filling device 100 to move, making it easier to operate and use.

[0097] In some embodiments, the support portion 31 includes a first support body 311, a second support body 312, and a slide rail 313. The glue dispensing assembly 20 is disposed on the first support body 311. The second support body 312 is spaced apart from the glue dispensing assembly 20 and connected to the first support body 311. The slide rail 313 is disposed on one side of the second support body 312 and extends along the glue filling assembly 11 toward the glue dispensing assembly 20. The driving portion 32 includes a driving body 321 and a sliding body 322. The driving body 321 is disposed on the second support body 312 and connected to the sliding body 322. The sliding body 322 is slidably disposed on the slide rail 313 and connected to the glue filling component 112. The driving body 321 drives the sliding body 322 to move the glue filling component 112 relative to the glue dispensing assembly 20. In this embodiment, the driving body 321 may be a cylinder.

[0098] In this way, by arranging the glue discharging assembly 20 and the driving part 32 on the first support body 311 and the second support body 312 respectively, the support part 31 can stably support the glue dispensing mechanism 10 and the glue dispensing assembly 20, preventing the glue dispensing mechanism 10 from shaking when moving relative to the glue dispensing assembly 20, thereby improving the glue dispensing stability; by arranging the slide rail 313 to extend in the direction from the glue dispensing assembly 11 to the glue dispensing assembly 20 to limit the movement direction of the glue dispensing member 112, the stopper 12 connected to the glue dispensing member 112 always reciprocates in the direction from the glue dispensing assembly 11 to the glue dispensing assembly 20, so that the stopper 121 accurately moves toward or away from the second glue outlet 22, thereby improving the glue dispensing accuracy. In other embodiments, the glue dispensing assembly 20 and the driving part 30 can also be arranged as two separate, unconnected structures.

[0099] See also Figure 2 and Figure 4In some embodiments, the glue discharging assembly 20 includes an adapter 23 and a glue discharging member 24. The adapter 23 has a first channel 231 for accommodating the stopper 12 and communicating with the glue passage 122. The glue discharging member 24 is connected to the adapter 23 and has a second channel 241 and a second glue outlet 22. The second channel 241 communicates with the first channel 231 and the second glue outlet 22, respectively. The second channel 241 and the first channel 231 form the glue discharging channel 21.

[0100] In this way, by setting the second channel 241 to connect with the first channel 231 to form the glue outlet channel 21, the first channel 231 and the second channel 241 can limit the flow path of the colloid in the glue outlet channel 21, so that the colloid flows along the extension direction of the first channel 231 and the second channel 241, so that the colloid can stably flow from the second glue outlet 22 to the product to be glued, thereby improving the glue pouring stability.

[0101] To ensure the tightness of the colloid flow channel, a fourth sealing member 28 is provided on the adapter 23. The fourth sealing member 28 seals the gap between the stopper 12 and the first channel 231, thereby preventing glue from overflowing when the stopper 12 moves. In this embodiment, the fourth sealing member 28 is sleeved on the stopper 12.

[0102] In some embodiments, the glue discharge component 20 further includes a second connecting member 25, which is sleeved on the outside of the glue discharge member 24 and the adapter 23 to connect the glue discharge member 24 and the adapter 23, and the second connecting member 25 is adapted to the adapter 23 and the glue discharge member 24.

[0103] In this way, the second connecting member 25 is sleeved on the glue outlet member 24 and the adapter member 23. The second connecting member 25 defines the positions of the glue outlet member 24 and the adapter member 23, so that the adapter member 23 can be stably connected to the glue outlet member 24 in the second connecting member 25, avoiding misalignment between the adapter member 23 and the glue outlet member 24, so that the first channel 231 is accurately connected to the second channel 241, so that the colloid is stably transported from the first channel 231 to the second channel 241, avoiding the colloid from overflowing from the connection between the glue outlet member 24 and the adapter member 23, and improving the stability of glue pouring.

[0104] In some embodiments, the glue discharging assembly 20 further includes a second sealing member 26 , which is disposed between the adapter 23 and the second connecting member 25 .

[0105] In this way, by arranging the second sealing member 26 between the adapter 23 and the second connecting member 25, a sealing structure can be formed between the adapter 23 and the second connecting member 25, thereby preventing external contaminants from entering the first channel 231 through the gap between the adapter 23 and the second connecting member 25, thereby improving the glue pouring stability. In addition, the second sealing member 26 also increases the friction between the adapter 23 and the second connecting member 25, so that the adapter 23 presses the glue outlet member 24 into the second connecting member 25, so that the adapter 23 is stably connected to the glue outlet member 24, preventing the glue from overflowing from the connection between the adapter 23 and the glue outlet member 24, thereby further improving the glue pouring stability.

[0106] In some embodiments, the glue discharging assembly 20 further includes a third sealing member 27. The third sealing member 27 is disposed between the adapter 23 and the glue discharging member 24, and can stably connect the adapter 23 to the glue discharging member 24, so that the first channel 231 connects to the second channel 241 to form the glue discharging channel 21, thereby ensuring stable flow of the glue in the glue discharging channel 21 and improving glue dispensing stability.

[0107] See also Figure 7 In some embodiments, the stopper 12 includes a main body 123 and a stopper 121. The cross-sectional area of ​​the main body 123 is larger than that of the stopper 121. The glue passage 122 is provided in the main body 123. The main body 123 is movably provided in the first passage 231. The stopper 121 is movably provided in the second passage 241. The cross-sectional area of ​​the first passage 231 is larger than that of the second passage 241. In this embodiment, since the main body 123 needs to be provided with the glue passage 122, the main body 123 needs to have a larger cross-sectional area while meeting the structural strength requirements. The stopper 121 only needs to meet the structural strength and stopping functions. In addition, the glue injection needle, that is, the second glue outlet 22 in this solution, is also very small. Therefore, the cross-sectional area of ​​the stopper 121 is smaller than that of the main body 123 to meet the requirements. Because the main body 123 is located within the first channel 231, the cross-sectional area of ​​the first channel 231 must be larger than that of the main body 123 to facilitate smooth flow of the colloid. The second channel 241, in conjunction with the stopper 121, has a smaller cross-sectional area than the first channel 231. This ensures a reasonable gap between the stopper 121 and the second channel 241, minimizing the amount of colloid contained within the gap and further reducing the effects of external temperature and pressure on the colloid.

[0108] In some embodiments, the cross-sectional area of ​​the second channel 241 is greater than the cross-sectional area of ​​the second glue outlet 22 . A conical transition structure 2411 is provided between the second channel 241 and the second glue outlet 22 , and the stopper 121 is structurally compatible with the conical transition structure 2411 .

[0109] See also Figure 5When the glue dispensing device 100 is in a closed state, the stopper 121 is driven by the stopper 12 to stably press against the conical transition structure 2411, so that the stopper 121 completely blocks the second glue outlet 22, thereby preventing the glue in the second channel 241 from flowing out through the second glue outlet 212;

[0110] See also Figure 6 When the glue pouring device 100 is in the glue pouring state, the stopper 121 is driven by the stopper 12 to separate from the conical transition structure 2411, so that the stopper 121 is separated from the second glue outlet 22, so that the glue is stably transported from the second channel 241 to the second glue outlet 212.

[0111] In this way, since the stop portion 121 is adapted to the conical transition structure 2411, the stop portion 121 can be accurately pressed against the conical transition structure 2411 to effectively block the second glue outlet 22, thereby accurately controlling the glue filling device 100 to stop glue discharge and avoiding glue discharge under the action of negative pressure after the second glue outlet 22 is blocked, thereby improving the glue filling accuracy.

[0112] See also Figure 8 In some embodiments, the stopper 12 is a columnar structure, a blind hole 124 is provided at one end of the stopper 12, and at least one through hole 125 connected to the blind hole 124 is provided on the side wall of the stopper 12 to form a glue passage 122, and the other end of the stopper 12 is a stop portion 121.

[0113] In this way, by providing a blind hole 124 at one end of the stopper 12 and providing a through hole 125 on the side wall of the stopper 12 that is connected to the blind hole 124, the colloid in the glue filling channel 1121 can flow directly into the glue passing channel 122 through the blind hole 124, so that the colloid passes through the inside of the stopper 12, avoiding the colloid passing through the bending channel, reducing the pressure loss during the flow of the colloid, and improving the glue filling accuracy; by setting the other end of the stopper 12 as the stopper 121, and setting it at a different position of the stopper 12 with a gap from the through hole 125, the stopper 121 can be stably pressed against the second glue outlet 22 when the glue filling device 100 is in a closed state, avoiding the colloid flowing out of the through hole 125 from flowing out of the second glue outlet 22, and further improving the glue filling accuracy.

[0114] It is understandable that the number of through holes 125 can be two, three, four, etc., and multiple through holes 125 are spaced apart on the side wall of the stopper 12 and connected to the blind hole 124. In this way, by providing multiple through holes 125, the glue in the glue passage 122 can be quickly transported to the glue outlet passage 21, avoiding pressure loss during the glue flow process, thereby further improving the glue dispensing accuracy.

[0115] The working process of the glue filling device 100 is roughly as follows:

[0116] First, the operator injects the glue into the glue pouring channel 1121 through the glue injection part 113;

[0117] Next, the driving unit 32 drives the glue filling component 112 to move in a direction away from the second glue outlet 22 , and the stopper 121 disengages from the conical transition structure 2411 to open the second glue outlet 22 .

[0118] Then, the colloid is directly transported from the glue filling channel 1121 to the glue passing channel 122 under the drive of the conveying member 114. After passing through the glue channel 122, the colloid is transported from the second glue outlet 22 to the product to be glued.

[0119] Finally, after the glue filling is completed, the driving unit 32 drives the glue filling component 112 to move toward the second glue outlet 22 , and the stopper 121 presses against the conical transition structure 2411 to block the second glue outlet 22 , and the glue stops flowing out of the second glue outlet 22 .

[0120] The above-mentioned glue filling device 100 is provided with a glue passage 122 on the stopper 12, so that the glue in the glue filling passage 1121 flows directly to the inside of the stopper 12, avoiding the glue passing through too many bends and reducing the pressure loss during the flow of the glue. Moreover, since the stopper 12 is connected to the bottom of the glue filling part 112, the flow path length of the glue is further reduced, so that the glue is less affected by the external pressure and temperature, so that the glue filling device 100 can accurately control the glue output of the glue, thereby improving the glue filling accuracy.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
