The lens of the mobile phone 13 includes a lens outer cylinder 131 and a lens 132 embedded in the outer lens casing 131. When dispensing, the mobile phone lens 13 is clamped on the jig 11, and the fixture 11 drives the mobile phone lens 13 to rotate. The dispensing squeegee 12 is dispensed between the outer edge of the lens 141 and the inner wall of the lens outer cylinder 131. As shown in Fig. 2, when dispensing, the ideal condition is that the center 130 of the mobile phone lens 13 (at the top corner of the triangle in the figure) coincides with the rotation center of the jig u (the center of the small circle in the center of the figure), and dispenses. The muzzle 121 of the grab 12 can be dispensed completely along the outer edge of the lens 132. In recent years, as the size of the mobile phone lens 13 is getting smaller and smaller, the processing accuracy is also getting higher and higher, as shown in FIG. 3, when the mobile phone lens 13 is clamped on the jig 11, and the mobile phone The center 13 of the lens 13 does not coincide with the center 110 of the jig 11 and the error amount is small when the error distance is generated. Since the size of the lens 13 of the mobile phone is small, the lens of the mobile phone 13 is rotated to perform dispensing. In the process, it will also cause the 201008661 nozzle of the rubber to grab the I] and move to the lens outer tube 13ι, and then move to the lens 132', so that the glue can not be exactly on the periphery of the lens Π2.

The point is executed, the method includes the following steps: Step 5 !: Obtain the error distance of the rotation center 231 of the jig 23 and the center 40 of the to-be-adhesive member 4 of the household G. Please refer to Fig. 7 Fig. 8 ® 1G, Fig. u' for dispensing. The component to be dispensed is placed on the tool 23, and the axis platform 241 is driven to be displaced, so that the image capturing unit π! is displaced directly above the component to be dispensed 4, and the fixture 23 is used to obtain the fixture 23 and The top view image of the dispensing member 4 (i.e., on the χ γ plane, then the image is transmitted to the recognition software 262, and the center of rotation 231 of the jig 23 and the center of the component to be dispensed 4 are detected by the identification soft boat 262. The error distance between 〇 is D. 0 Step 52: Displace the dispensing 27 to the position after the correction. Refer to Figure 7, Figure 9, Figure m, because theoretically, the + heart of the adhesive 4 40 should coincide with the center of rotation 231 of the jig 23 and the glue grab 27 is 'moved to the original dispensing position A (as indicated by A in Figure U) and the dispensing begins, but due to the dispensing of the glue 4 There is an error relationship between the center 4〇 and the rotation of the fixture 〜231. Therefore, it is necessary to correct the dispensing η to move to a corrected dispensing position 'such as the circle u point The position shown by the needle 271 can be correctly dispensed. 201008661 Therefore, the error distance d obtained by the recognition software 262 in step 51 is transmitted to the calculation unit 2〇2 of the control module 20 for the calculation unit. 202 calculates an axis correction amount and an axis correction amount 疋dx according to the following formula - do one cos(y41 + N) sin(^l + ^) 8Ϊη(^1 + ΛΓ)Τ〇Λ:-£^' Sin(^l + 7V)J[〇^-cy cy

Therefore, after the image capturing unit 261 obtains the image of the jig 23 and the component to be dispensed 4, the control unit 201 moves the image capturing unit 261 through the motor driving the yoke platform 241, and simultaneously corrects the y-axis according to the X-axis. The amount, so that the dispensing grab 27 is moved to the corrected dispensing position (ie [pX+dx, py+dy]), which is the position where the dispensing can be performed correctly. Step 53: The fixture 23 is driven to rotate the glue member 4 in the XY plane, and the glue grab 27 is synchronized with the rotation of the jig 23 by the offset position of the original dispensing center a with the error distance D as the center. Displace and dispense on the XY plane. Referring to Figure 7 and Figure U, when the glue grab 27 is moved to the school 10 201008661 two glue:, the fixture 23 starts to drive the glue to be rotated 4; sound 2 = a unit angle (the unit angle referred to here has Possible bit angle 订 end view setting), calculation software 2G2 is based on

The __ area turn-circle dispensing operation is completed. Note that in the above formula, the value of the Μ angle taken in the next calculation is the angle value of 上1+Ν of the upper-order, in other words, in each calculation, Α1 is added and one is added. Unit angle Ν. In total. In the process of the tool 23 driving the glue member 4 to rotate and dispensing the glue to perform the dispensing process, the corrected displacement amount is calculated through the calculation unit 2G2 with the error distance D, so that the glue can be grabbed 27 with the fixture. The rotation of 23 is performed in synchronization with the position correction and the knee is performed. Therefore, by the above method, even if an error distance D is generated between the rotation center 231 of the jig 23 and the center 4 of the adhesive member 4, the dispensing operation is still completed 6 without dispensing. error. And as shown in Fig. 11, as a whole, when the jig 23 drives the glue component 4 to rotate for one week, the displacement track after the glue correction 4 is shaped to be centered on the original dispensing position a, and the error distance D Rotated for a radius for a week. 11 201008661 and as shown in FIG. 9 , in the embodiment, the setting of the dispensing grab 27 is such that the dispensing needle 271 is inclined at an angle to avoid when the dispensing grab 27 is driven downward to move adjacent to the dispensing piece " ; it is easy to interfere with the adhesive member 4 to make the dispensing needle 271 more difficult to extend at the corner between the outer edge of the lens 42 and the inner wall of the lens outer cylinder 41. In summary, the present invention is to obtain the error distance D between the center of rotation 231 of the jig 23 and the center 40 of the component to be dispensed 4, and then use the error distance D to calculate the dispensing when the jig 23 rotates by one unit angle. The gun 27 needs to follow the displacement amount of the offset, and when the jig 23 drives the rotation of the glue member 4, the glue grab 27 is synchronized with the rotation of the center 231 of the center of the glue member 4 around the rotation center 231 of the jig 23 The displacement 'allows the distance between the glue grab 27 and the center 40 of the glue piece* to be relatively immobile, and the problem of dispensing error can be solved. In summary, the present invention compensates for the offset of the displacement of the center 40 of the adhesive member 4 and the center of rotation of the tool 23, 231 when the error occurs. Conventional (4) Dispensing 12 can not correctly point to the problem of the periphery of the lens 132.
