[0073] In this embodiment, the fixing member 112 is arranged in a vertical direction. When it is necessary to adjust the angle of the linkage body 1211 relative to the fixing member 112, the locking body 1212 is first rotated to loosen the linkage body 1211 and the fixing member 112, and then the linkage body 1211 is driven to rotate relative to the fixing member 112 manually or through an automated mechanism to adjust the inclination angle of the linkage body 1211 relative to the fixing member 112.

Specifically, if the structure to be dispensed is a straight groove, the needle 1322 with a straight structure can be installed on the dispensing tube 1321; if the structure to be dispensed is a groove with a small opening and a large inner cavity, the needle 1322 with a folded line structure can be installed on the dispensing tube 1321.

[0078] See also Figure 3 The floating body 1223 includes four spring pieces 1223a which are accommodated in the sleeve 1221 and symmetrically arranged with the glue dispensing tube 1321 as the center. In this embodiment, each spring piece 1223a includes a horizontal portion 1223b and a vertical portion 1223c in a wave shape, one end of the horizontal portion 1223b is connected to the glue dispensing tube 1321, and the two ends of the vertical portion 1223c are respectively connected to the other end of the horizontal portion 1223b and the inner wall of the sleeve 1221, and the elastic force direction of the vertical portion 1223c is perpendicular to the elastic force direction of the horizontal portion 1223b.

[0079] See also Figure 1 and Figure 2 The rotating assembly 140 includes a rotating driving member 141 installed on the side of the bracket 111 away from the card slot 111a, a transmission member 142 that is rotatably connected to the linkage body 1211 and is in transmission cooperation with the driven body 1222, and a telescopic member 143 that is roughly strip-shaped and has two ends that are rotatably connected to the rotating driving member 141 and the transmission member 142. In this embodiment, the rotating driving member 141 is a servo motor, which is used to drive the telescopic member 143 to rotate.

[0080] In this embodiment, the transmission member 142 includes a transmission body 1421 rotatably connected to the linkage body 1211 and substantially cylindrical, and a driving gear 1422 connected to the transmission member 142 and meshing with the driven body 1222 .

[0081] See also Figure 1 and Figure 2In this embodiment, the telescopic member 143 includes a telescopic rod 1431 and two movable pins 1432 in a cross structure. One of the movable pins 1432 is movably provided at one end of the telescopic rod 1431 and the output end of the rotary drive member 141, and the other movable pin 1432 is movably provided at the other end of the telescopic rod 1431 and the transmission body 1421. The rotation axis of the telescopic member 143 relative to the rotary drive member 141 is the first axis, the rotation axis of the telescopic member 143 relative to the transmission member 142 is the second axis, and the rotation axis of the linkage member 121 relative to the fixed member 112 is the third axis. The first axis, the second axis, and the third axis are parallel to each other, and the first axis is perpendicular to the rotation axis of the telescopic member 143 when it rotates under the drive of the rotary drive member 141.

[0082] The dispensing device 100 can select the corresponding needle 1322 structure based on the structure to be dispensed, and the function of the rotating driving member 141 driving the telescopic member 143 to drive the transmission member 142 to rotate can be selectively used based on the structure of the needle 1322. Specific examples are as follows:

[0083] like Figure 4 As shown, the needle 1322 is a linear structure, and the linkage member 121 and the fixing member 112 are both in a vertical state. On this basis, the needle 1322 can be driven to move linearly through the above-mentioned dispensing device 100 to achieve dispensing operations on regular open structures such as grooves.

[0084] like Figure 1 As shown, the needle 1322 is a broken line structure, and the linkage member 121 is inclined relative to the fixing member 112. Figure 4 In the dispensing device 100, the telescopic rod 1431 in the dispensing device 100 is stretched. On this basis, the dispensing device 100 can drive the needle 1322 to move linearly, and cooperate with the rotating driving member 141 to drive the telescopic member 143 to drive the transmission member 142 to rotate, so that the driving gear 1422 of the transmission member 142 drives the driven body 1222 to rotate, so that the driven body 1222 drives the sleeve 1221 and the needle 1322 to rotate, so as to realize the dispensing operation of complex structures such as small openings and large inner cavities.

[0085] Taking the dispensing operation of complex structures such as small openings and large inner cavities as an example, the working process of the above-mentioned dispensing device 100 is roughly as follows: first adjust the angle of the linkage part 121 relative to the fixed part 112 to adapt to the required structure to be dispensed, and then drive the dispensing device 100 to move through the fixed seat 110 so that the needle 1322 extends into the structure to be dispensed, and finally, the rotating drive part 141 drives the telescopic part 143 to drive the transmission part 142 to rotate, so that the driving gear 1422 of the transmission part 142 drives the sleeve 1221 and the needle 1322 to rotate through the driven body 1222, thereby realizing the dispensing operation of complex structures such as small openings and large inner cavities.

[0086] Therefore, in the above-mentioned dispensing device 100, the needle 1322 rotates under the drive of the mounting member 122, and can implement dispensing on grooves with curved side walls and structures with small openings and large inner cavities, thereby improving the applicability of the dispensing device 100.

[0087] It is obvious 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 present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
