SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a dispensing device that can avoid the occurrence of a striker 〇 095129527 Form No. 101 0101 Page 3 / Total 11 Page 1003262324-0 [0005] 1352627 100 July 07 Correction Replacement [0006] A dispenser includes a syringe and a needle in communication with the barrel, the needle including an elastic portion and a needle tip, the needle tip being in communication with the barrel through the elastic portion. [0007] A dispensing device comprising one of the above dispensers and a holding mechanism. The syringe of the dispenser is connected to the holding mechanism, and the holding mechanism is used for fixing and controlling the dispenser to perform the dispensing operation.

[0008] The dispensing device can change the position of the needle when the needle is in contact with the component to be dispensed, and the needle can be returned to the original position after the external force disappears, thereby avoiding damage to the needle or waiting. Dispensing components to reduce costs and improve product yield. [Embodiment] In order to further clarify the present invention, the following preferred embodiments are described in detail below with reference to the drawings. [0010] Embodiment 1:

Referring to FIG. 1, a dispensing device 100 in an embodiment of the present invention includes a dispenser 10 and a holding mechanism 13. The dispenser 10 includes a needle 11 and a syringe 12. The needle 11 is in communication with the syringe 12. The syringe 12 is coupled to a holding mechanism 13. [0012] The needle 11 includes an elastic portion 111 and a needle tip portion 112. The elastic portion 111 is integrally formed with the needle tip portion 112 and is hollow to facilitate the flow of the adhesive. [0013] Both ends of the elastic portion 111 are respectively connected to the syringe 12 and the tip portion 112, and the elastic portion 111 may be a spring structure. When the needle 11 is in contact with the component to be dispensed, the tip 112 can be deflected away from the phase contact while 095129527 Form No. A0101 Page 4 of 11 1003262324-0 1352627 Correction replacement page of July 19, 100 After the external force disappears, the needle tip portion 11 2 is returned to the original position. [0014] The needle tip portion 112 is used to dispense glue to perform a dispensing operation on the dispensing component. [0015] The holding mechanism 13 can be a three-axis controller for fixing and controlling the dispenser 10 to facilitate dispensing operations. [0016] Referring to FIG. 2, a dispensing operation can be performed for a lens module 20 by using the dispensing device 100. The lens module 20 includes a lens barrel 21, a plurality of optical elements 22, and a plurality of spacer rings 23.

[0017] Taking the first embodiment as an example, the dispensing position may be a shortest distance from the needle 11 to the side wall of the lens barrel 21 and a fixed position determined by the vertical distance of the needle 11 to the spacer ring 23 near the upper surface of the needle. This fixed position is set as needed. [0018] Taking the lens module 20 as an example, the dispensing method includes the following steps: [0019] Step 1: providing a lens module 20 to be assembled, the lens module 20 to be assembled includes a lens barrel 21, and a plurality of Optical element 22 and a plurality of spacer rings 23. [0020] Step 2: Providing a dispensing device 100 as described above. [0021] Step 3: The needle 11 of the dispensing device 100 is inserted into the lens barrel 21, the needle 11 is adjacent to the upper surface of the spacer ring 23 and the inner wall of the lens barrel 21, and the upper surface of the needle 11 and the spacer ring 23 and the inner wall of the lens barrel 21 There is a gap for dispensing glue. [0022] Step 4: Adjust the needle 11 of the dispensing device 100 to a predetermined dispensing position, that is, adjust and fix the needle 11 of the dispenser 10 to a predetermined dispensing position by the holding mechanism. 095129527 Form No. A0101 Page 5 of 11 1003262324-0 1352627 Correction Replacement Page of July 19, 100 [0023] Step 5: After fixing the dispensing device 100, while the lens module 20 is rotating, the dispensing device 100 uniformly presses an appropriate amount of glue on the dispensing position. [0024] Step 6: The dispensing device 100 is taken out to complete the dispensing operation. [0025] Embodiment 2: [0026] Referring to FIG. 3, the dispensing device 300 of the second embodiment of the present invention includes a dispenser 30 and a holding mechanism 33. The needle 31 of the dispenser 30 includes an elastic The portion 311, the set of contacts 312, and a tip portion 313. The socket portion 312 is integrally formed with the needle tip portion 313. [0027] The socket portion 312 is a columnar body for connecting the elastic portion 311 and the needle tip portion 313 to facilitate the replacement of the needle tip portion 31 3 . The elastic portion 311 is used for the needle 31 to deflect the needle 31 away from the phase contact when in contact with the component to be dispensed, and to return the needle 31 to the home position after the external force disappears.

[0029] The elastic portion 311, the socket portion 312, and the needle tip portion 313 of the needle 31 are all hollow, facilitating the outflow of the glue. The socket portion 312 of the needle 31 in the second embodiment may be adhered to the elastic portion 312 by an adhesive, or may be connected to the elastic portion 311 by providing a screw on the socket portion 312. [0031] During the dispensing process of the lens module 20, the dispensing device 100, 300 can effectively avoid the occurrence of a striker due to the action of the elastic portions 111, 311. [0032] In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above is only a preferred embodiment of the present invention, the present invention 095129527 Form No. A0101 Page 6 / Total 11 pages 1003262324-0 1352627 100 July 19, the scope of the shuttle replacement page is not implemented as described above The equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
