For the present invention being done further explanation, lift a preferred embodiment and conjunction with figs. and be described in detail as follows.
See also Fig. 1 and Fig. 2, the point glue equipment of present embodiment comprises an adhesive dispensing device 10 and a glue tube base 20, this adhesive dispensing device 10 comprises a syringe needle 11 and a syringe 12, this syringe needle 11 is connected on the described syringe 12 mutually, and this glue tube base 20 comprises a cylinder base 21, a baffle plate 22 and a sensing apparatus.Described baffle plate 22 is fixed on the described cylinder base 21; Described sensing apparatus comprises that two sensors 23,24 are arranged on the sidewall of close syringe needle of described cylinder base 21.
Described cylinder base 21 can be a cylinder-like body, is used for the syringe 12 of ccontaining adhesive dispensing device 10.
Described baffle plate 22 can be an arc sheet baffle plate, it is fixed in cylinder base 21 near an end of syringe needles 11 and parallel with syringe needle 11, itself and cylinder base 21 are one-body molded, also can use other modes, as fixing with screw, this baffle plate 22 is used for preventing being sprayed onto at a glue process viscose glue treats a glue element central area, treats a glue element thereby avoid polluting.
Described sensing apparatus comprises two sensors 23,24.These two sensors 23,24 can be two radar range finders, it is fixed on the end section edge of cylinder base 21, and be positioned at the same side of cylinder base 21 with baffle plate 22, and be distributed in the both sides of baffle plate 22, this sensor 23,24 all is used for the distance of sensing syringe needle 11 to some glue position.
See also Fig. 3, above-mentioned point glue equipment can carry out a glue operation for a camera lens module 30.This camera lens module 30 comprises a lens barrel 31, several optical elements 32 and an if spaced ring 33.
Point glue position can be the vertical range determined fixed position of syringe needle 11 to the bee-line of the sidewall of lens barrel 31 and syringe needle 11 to the upper surface of the close syringe needle of spaced ring 33.Syringe needle 11 arrives the bee-line of lens barrel 31 inwalls and the distance of close syringe needle 11 upper surfaces that syringe needle 11 arrives spaced ring 33 is measured by sensor 23,24 respectively, and compares with standard value, adjusts syringe needle to described some glue position according to comparative result.Set as required by the predetermined point glue position that this standard value obtains.
With above-mentioned camera lens module 30 is example, and its dispensing method may further comprise the steps:
Step 1: a camera lens module 30 to be assembled is provided, and this is waited to assemble camera lens module 30 and comprises a lens barrel 31, several optical elements 32 and a spaced ring 33
