[0069] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0070] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0072] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0073] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0074] like Figures 1 to 4As shown, this embodiment provides a glue dispensing device 1, which includes a base 11, a follower assembly 12, a colloid receiving member 14 and a glue dispensing member 13. The base 11 is provided with a receiving space 111, and the follower assembly 12 is arranged on the base 11. The follower assembly 12 includes a first follower 121, a second follower 122 and a first elastic member 123. The first follower 121 is located in the receiving space 111 and can move relative to the base 11 along a first direction Z. The first follower 121 and the second follower 122 are distributed along the first direction Z. The first follower 121 and the second follower 122 are connected by the first elastic member 123. The first elastic member 123 is annular. The first elastic member 123 wraps part of the first follower 121 and part of the second follower 122. The second follower 122 can move relative to the first follower 121 along the second direction Y and the third direction X. The colloid receiving member 14 is used to contain colloid, and the dispensing member 13 is connected to the colloid receiving member 14 so as to transport the colloid to the dispensing member 13 through the colloid receiving member 14. The dispensing member 13 is also connected to the second follower 122 so that the dispensing member 13 moves relative to the base 11 along the first direction Z, the second direction Y and the third direction X to achieve dispensing of the three-dimensional dispensing structure. The first direction, the second direction and the third direction are perpendicular to each other.

[0075] The follower component 12 of this embodiment can move relative to the base 11, and the dispensing component 13 is connected to the follower component 12 so that the dispensing component 13 can move relative to the base 11, so that the dispensing component 13 can automatically adjust the needle position as the three-dimensional dispensing structure changes, thereby realizing follow-up dispensing and reducing the risks of scraping the needle or blocking the needle when the dispensing component 13 is dispensing the three-dimensional dispensing structure.

[0076] like Figure 1 As shown, in this embodiment, the dispensing component 13 and the colloid receiving component 14 are connected through the air pipe 19 rather than directly connected, so that the dispensing component 13 is connected to the follower component 12 and can realize active dispensing of the three-dimensional dispensing structure in cooperation with the follower component 12.

[0077] It should be noted that the dispensing member 13 moves along the second direction Y and the third direction X, which does not mean that the dispensing member 13 can only move along the two directions, but the second direction Y and the third direction X form a plane, that is, the dispensing member 13 can move in all directions.

[0078] In this embodiment, the end of the dispensing member 13 away from the needle is connected to the second follower 122, and the second follower 122 is connected to the first follower 121 through the first elastic member 123. When the dispensing member 13 contacts the three-dimensional dispensing structure higher than the dispensing port in the second direction Y or the third direction X, the dispensing member 13 will deviate with the movement to reduce the risk of the dispensing member 13 scraping the needle. At this time, the second follower 122 is pushed by the dispensing member 13 to move relative to the first follower 121 and stretch the first elastic member 123. With the movement, when the dispensing member 13 is away from the three-dimensional dispensing structure, the pulling force applied to the first elastic member 123 can be released, and the first elastic member 123 drives the second follower 122 to reset through its own resilience, thereby realizing the reset of the dispensing member 13.

[0079] The first follower 121 is disposed in the accommodating space 111 of the base 11 and can move relative to the base 11. When the dispensing member 13 contacts the three-dimensional dispensing structure in the first direction Z, the dispensing member 13 pushes the first follower 121 to move upward through the second follower 122 to reduce the risk of the dispensing member 13 being scraped. As the dispensing member 13 moves away from the three-dimensional dispensing structure, the second follower 122 can be pushed downward to achieve the reset of the dispensing member 13.

[0080] Furthermore, in order to realize the first follower 121 driving the dispensing member 13 to reset in the first direction Z, as shown in FIG. Figures 2 to 4 As shown, the dispensing device 1 further includes a first limiter 15, which is located in the accommodating space 111 and connected to the base 11, and there is a spacing between the first follower 121 and the first limiter 15 along the first direction Z. The follower assembly 12 further includes a second elastic member 124, one end of the second elastic member 124 is connected to the first limiter 15, and the other end is connected to the first follower 121, so that the first follower 121 can move along the first direction Z relative to the base 11.

[0081] In this embodiment, when the first follower 121 is pushed by the dispensing member 13, the first follower 121 moves upward by compressing the second elastic member 124. When the dispensing member 13 is away from the three-dimensional dispensing structure, the pressure applied to the second elastic member 124 can be released, and the second elastic member 124 drives the first follower 121 to reset through its own resilience, thereby resetting the dispensing member 13.

[0082] The second elastic member 124 may be a spring.

[0083] like Figure 4As shown, a receiving cavity 151 is provided on the side of the first position-limiting member 15 facing the first follower 121, and a portion of the second elastic member 124 away from the first follower 121 is located in the receiving cavity 151. In this embodiment, by providing the receiving cavity 151 in the first position-limiting member 15, a portion of the second elastic member 124 is disposed in the receiving cavity 151, thereby reducing the space occupied by the second elastic member 124, which is conducive to miniaturization of the dispensing device 1. At the same time, the second elastic member 124 is limited by the receiving cavity 151, thereby reducing the risk of bending and deformation of the second elastic member 124 when compressed, and extending the service life of the second elastic member 124.

[0084] like Figure 5 and Fig.11 As shown, a limiting groove 121b is provided on one side of the first follower 121 facing the first limiting member 15, and a portion of the second elastic member 124 away from the first limiting member 15 is located in the limiting groove 121b. In this embodiment, the second elastic member 124 is limited by the limiting groove 121b, thereby reducing the risk of bending and deformation of the second elastic member 124 when compressed, and extending the service life of the second elastic member 124.

[0085] like Figures 4 to 6 As shown, in some embodiments, the base 11 is provided with an annular boss 112, and the middle of the annular boss 112 is a through hole 113, and part of the follower assembly 12 can extend out of the accommodation space 111 along the through hole 113 so as to be connected with the dispensing member 13. The first follower 121 also includes a limiting portion 121c, which is overlapped on the annular boss 112 to limit the follower assembly 12 from completely leaving the accommodation space 111.

[0086] Specific as Figure 5 and Figure 6 As shown, the portion of the first follower 121 connected to the second follower 122 extends out of the accommodation space 111 and is located in the through hole 113, and the first follower 121 and the second follower 122 are connected in the through hole 113. The diameter of the through hole 113 is defined to be larger than the maximum outer diameter of the first elastic member 123, so that the second follower 122 can move relative to the first follower 121 in the through hole 113.

[0087] like Figure 4 , Figure 8 and Fig. 9 As shown, the first limiter 15 is mounted on the annular boss 112, and the first limiter 15 is provided with an escape portion 152, and the escape portion 152 is used to escape the limiter 121c. In this embodiment, by providing the escape portion 152 on the first limiter 15, a space is reserved for the overlapped cooperation between the limiter 121c and the annular boss 112. In addition, the height of the escape portion 152 is greater than the thickness of the limiter 121c, so as to reserve space for the first follower 121 to move along the first direction Z. Figure 5As shown, the limiting portion 121c can be set to a triangular structure, that is, the first limiting portion 121c and the annular boss 112 have three connection positions to ensure that the first limiting portion 121c and the annular boss 112 are firmly connected.

[0088] like Figure 6 and Figure 7 As shown, in some embodiments, the dispensing device 1 further includes a second stopper 16, which is mounted on the annular boss 112 and is used to limit the rotation of the follower assembly 12 when it is reset along the first direction Z, to ensure that the follower assembly 12 returns to the initial position, and to reduce the risk of friction between the first follower 121 and the first stopper 15 when the first follower 121 moves due to the contact between the stopper 121c of the first follower 121 and the first stopper 15 when the follower assembly 12 rotates. In addition, by limiting the rotation of the follower assembly 12, the dispensing component 13 is limited to rotate, so as to reduce the risk of twisting of the air pipe 19 between the dispensing component 13 and the colloid receiving component 14 after the dispensing component 13 rotates.

[0089] Specifically, the second stopper 16 may be a spherical structure, such as a steel ball. Figure 7 As shown, the annular boss 112 is provided with a first recessed portion 112a, the second stopper 16 is located in the first recessed portion 112a, and a portion of the second stopper 16 protrudes out of the first recessed portion 112a, and the second stopper 16 can rotate relative to the first recessed portion 112a. Fig.12 As shown, the limiting portion 121c is provided with a second recessed portion 121c1. When the follower assembly 12 is reset along the first direction Z, the second limiting member 16 can cooperate with the second recessed portion 121c1.

[0090] In this embodiment, the second position limiting member 16 is arranged in the first recessed portion 112a. Since the second position limiting member 16 is a spherical structure, the part of the second position limiting member 16 protruding from the first recessed portion 112a is arc-shaped, and the structure of the second recessed portion 121c1 corresponds to the protruding part of the second position limiting member 16, so that when the first follower 121 is reset, the protruding part of the second position limiting member 16 can guide the second recessed portion 121c1, so that when the first follower 121 is reset, the protruding part of the second position limiting member 16 can cooperate with the second recessed portion 121c1, thereby realizing the reset of the first follower 121.

[0091] like Figure 7 As shown, the annular boss 112 is provided with a support portion 112b, the second stopper 16 is overlapped on the support portion 112b, and the first recessed portion 112a is provided on the support portion 112b. Part of the support portion 122b extends above the through hole 113, increasing the contact area with the stopper 121c and improving the support force on the first follower 121.

[0092] like Figures 10 to 14As shown, in some embodiments, along the circumference of the dispensing device 1, the outer wall of the first follower 121 is provided with a first mounting groove 121a, and the outer wall of the second follower 122 is provided with a second mounting groove 122a. The first elastic member 123 is a rubber ring with a C-shaped cross section, and is provided with an upper edge portion 123a, a middle portion 123c and a lower edge portion 123b, the middle portion 123c connects the upper edge portion 123a and the lower edge portion 123b, and the upper edge portion 123a and the lower edge portion 123b are bent and protruded inwardly of the ring relative to the middle portion 123c. The upper edge portion 123a is clamped in the first mounting groove 121a, and the lower edge portion 123b is clamped in the second mounting groove 122a.

[0093] In this embodiment, the upper edge 123a of the first elastic member 123 is clamped in the first mounting groove 121a, and the lower edge 123b of the first elastic member 123 is clamped in the second mounting groove 122a, so that the first elastic member 123 is connected to the first follower 121 and the second follower 122, which is convenient for the assembly and disassembly of the two. In addition, because the first elastic member 123 is a rubber ring, it has a certain elasticity, and the first follower 121 and the second follower 122 are distributed along the first direction Z, so that when the second follower 122 is pushed along the second direction Y and the third direction X, it can move relative to the first follower 121, and under the rebound force of the first elastic member 123, drive the second follower 122 to reset. In this embodiment, the first elastic member 123 can realize the connection between the first follower 121 and the second follower 122, and can also realize the movement of the second follower 122 relative to the first follower 121 and reset the second follower 122.

[0094] like Figure 2 and Figure 6 As shown, the base 11 is provided with an installation opening 114, and the installation opening 114 is communicated with the accommodating space 111. The glue dispensing device 1 also includes an end cover 17, and the end cover 17 is fixedly connected to the base 11 so that the end cover 17 can cover the installation opening 114. By providing the installation opening 114 on the base 11, the first limit member 15, the first follower 121, the second elastic member 124 and other parts can be installed in the accommodating space 111 along the installation opening 114.

[0095] like Figure 2 As shown, the dispensing device 1 further includes a support seat 18, and the base 11 and the colloid receiving member 14 are mounted on the support seat 18. Specifically, the support seat 18 can be provided with a first mounting hole and a second mounting hole, and part of the base 11 is connected to the support seat 18 through the first mounting hole, and part of the colloid receiving member 14 is connected to the support seat 18 through the second mounting hole.
