Referring to FIG. 1 , FIG. 2 and FIG. 3 , the method for measuring the dispensing amount of the embodiment includes: Step 1 : providing a dispensing device 1 and a component to be dispensed. The dispensing device 10 includes a dispensing tip u, a dispensing syringe 12, and a controller 13, the controller 13 including a holding device 14 and a recorder. The dispensing needle u and the dispensing syringe 12 are connected and fixed to the 12-end of the dispensing syringe, and the dispensing needle 12 is fixed to the holding device 14. The holding device 14 controls the cartridge 12 and the dispensing needle 11 to move or rotate in various directions. The recorder 15 can record the coordinate value of the dispensing needle 11 at any position. The controller may further include an image sensor 16 for transmitting and amplifying the image of the dispensing needle and its surroundings to a control monitoring screen to facilitate positioning control and monitoring of the dispensing needle 1; The image sensor 16 may be a cCD (Charge-Couple Device) image sensor, a CMOS (Complementary Metal-Oxide Semiconductor) image sensor, or the like. The component to be dispensed can be any component of the lens module that needs to be glued and fixed. In this embodiment, the component to be dispensed is a spacer ring 21. The lens module 20 includes a spacer ring 21, a lens barrel 22, a lens 23, and a stop ring 24. The spacer ring 21 is sleeved on the inner wall of the lens barrel 22 and has a through hole 25. The spacer ring 21 may be annular and has an outer diameter equivalent to the inner diameter of the lens barrel 21, the thickness of which may be set according to the optical requirements of the camera lens. The lens 23 is disposed between the spacer ring 21 and the stop ring 24. Specifically, the spacer ring 21, the lens 23 and the stop ring 24 are sequentially housed inside the lens barrel 22, and are preferably disposed coaxially. In addition, the lens module 20 can be controlled to rotate. For example, the lens module 20 is placed on a rotating flat a to be rotated by the rotating platform. Step 2, using the dispensing device 1 to treat the dispensing component to point 3. The holding device 14 controls the dispensing needle 11 to move, and fixes it to the / temple dispensing position, for example, above the top surface of the spacer ring 21乂λ # Near the inside of the barrel 22. After positioning, the rotating lens pole set 20 and the control point are glued, and the glue 30 facilitates coating a circle on the top surface of the spacer ring 21. The head is wrongly glued by the top surface of the spacer ring 21, and other optical components such as filters can be adhered to the top of the spacer ring 21. The glue 30 should have a certain bonding strength, and it can be an ultraviolet (UV) glue or a thermosetting glue. In a third step, a reference point is determined on the axis of the lens module, and the -, point is used as a reference to determine the three-axis coordinate value of the position of the dispensing needle 11 . M. This reference In the present embodiment, the "dispensing element" is a spacer ring 21, the top surface of which is a toroidal surface, the toroidal point κ is located on the axis of the lens module, and the defect point is determined as a reference point. a, with the lens module axis as ice, which = any point to the outer circumference of the torus surface w ^ The first (four) ^ red axis perpendicular to the first radial direction γ axis. Therefore, the position of the dispensing point can be X, Y, 7r: the shell il is represented by any one of the shaft seat values, and the &## meter 15 records the value of the three-axis coordinate. The process of this field record 200813507 4 ^ to the edge point 31 can be transmitted to the orphan screen of the controller 13 by the image sensor i6, thereby facilitating the monitoring of the measurement process. J 0 " #一五五, control the needle n from the first edge point 31 to the edge point 32 of the glue 3〇 and record the third (four) value of the point, the first edge point ^, the second side ^ point 32 and the lens module The axis of 20 lies in a plane. In the example, the control state 13 controls the needle 11 to move from the younger-edge point 31 to the intersection line f of the surface of the glue 3〇 and the top surface of the spacer ring 21 by the holding device 14 and with the needle 11 and the intersection line. The contact point is the second edge point 32, the edge point 31, the second edge point 32, and the axis of the lens module 2A are located on a plane, and the recorder 15 records the three-axis coordinate value of the second edge point 32. During the process of the field, the measurement process can be monitored by the image sensor 16. The path of the clicker needle 11 moving from the first edge point 31 to the second edge point 32 may be a straight line or a curve. Preferably, the needle 11 moves the φ path to move first along the perpendicular line of the first edge point 31 to the axis to above the second edge point 32, and then parallel to the axial direction (four) to the second edge point 32. In step 6, according to the three-axis coordinate values of the first edge point 31 and the second edge point 32, the distribution amount of the glue 3 〇 in the parallel direction of the axis and the distribution amount of the vertical direction of the axis are obtained. In this embodiment, it is apparent that the amount of glue Mp on the plane of the first edge point 31, the second edge point 32, and the axis of the lens module 2G in the direction parallel to the axis of the lens module 20 is The first edge point weaves the second side 11 200813507 The Z-axis coordinate difference between the edge points 32 can be recorded as. The amount of glue 3 on the plane perpendicular to the axis can be calculated by the X-axis coordinate difference of the first edge point μ and the first edge point 32 and the Y-axis coordinate difference. The difference between the X-axis coordinate of the first edge point 31 and the second edge point 32 is that the coordinate difference of the γ-axis is AY:. Then, the distribution amount bi of the glue 30 in the vertical direction of the axis can be calculated by the Pitt's reason AXi and Δγ: specifically (ΔχΛδυ!2) 1/2. Step 7: Rotate the lens module 20 and repeat steps 4-6 to obtain a plurality of distributions of the glues 30 in the parallel direction and the vertical direction of the axis of the lens module 20, thereby evaluating the distribution of the glue 30. In this embodiment, the lens module 20 can be rotated by a moderate rotation, for example, the lens module 20 is rotated by 15 degrees, 30 degrees, or 60 degrees, and the first edge point is repeatedly moved from the first edge point to the second edge point. The process, after a plurality of rotations and measurement, can obtain a plurality of distribution amounts hi, h...hn of the glue 30 in the parallel direction of the axis of the lens module 20, and the glue 30 is perpendicular to the axis φ of the lens module 2 A plurality of distribution quantities bi, b2 ... bn. Comparing the distribution of a plurality of glues in the vertical direction of the axis, the distribution of the glue 3〇 in the direction can be obtained, and the distribution of the plurality of glues 3 in the parallel direction of the axis can be obtained in the direction of the glue 30. Distribution status. Tian Ran, the measurement process can be monitored by the image sensor during the whole measurement process. According to the distribution state of the glue obtained in the embodiment, the accurate correction of the dispensing parameters can be made, so that the dispensing condition of the next module is better, and the glue overflow, the amount of glue is too small, or the dispensing is uneven. The situation of the sentence. 12 200813507 This measurement method is directly with a needle.
