The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
A fully automatic needle position self-correction system according to the present application is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 3, the fully automatic needle position self-correcting system of the present application includes a needle fixing mechanism 1, an image detecting mechanism 2, a displacement measuring mechanism 3, a position adjusting mechanism 4, and a control system 5.
The needle holding mechanism 1 is used to replaceably mount a needle 6. Wherein, the needle 6 is fixedly arranged on the needle fixing mechanism 1 or is detached from the needle fixing mechanism 1 and replaced by another needle 6 in a manual mode. The needle 6 is located above the workpiece B to be processed (e.g., a quartz crystal) in the third direction Z and is used for dispensing (i.e., dispensing) the workpiece B to be processed through the needle 6.
The image detection mechanism 2 is used for detecting and acquiring the dispensing position information of the needle 6 on the workpiece B to be processed before and after replacement. The displacement measuring mechanism 3 is used for detecting and acquiring the height between the needle head 6 before and after replacement and the dispensing position of the needle head on the workpiece B to be processed. The control system 5 is connected with the image detection mechanism 2, the displacement measurement mechanism 3 and the position adjustment mechanism 4 in a communication mode and is used for calculating the deviation between the position of the needle 6 after replacement and the position of the needle 6 before replacement. Under the control of the control system 5, the position adjustment mechanism 4 corrects the position of the needle 6 after replacement to the position of the needle 6 before replacement.
The dispensing position refers to a position of a projection point on the workpiece B to be processed when the needle 6 does not dispense the glue before and after the replacement, or a position of a dispensing point on the workpiece B to be processed after dispensing the glue.
In the full-automatic needle position self-correcting system, when the needle 6 needs to be replaced, the image detection mechanism 2 detects and acquires the dispensing position information of the needle 6 before replacement on the workpiece B to be processed, and the displacement measurement mechanism 3 detects and acquires the height between the needle 6 before replacement and the dispensing position of the needle 6 on the workpiece B to be processed, so that the spatial position information of the needle 6 before replacement is acquired; then, the needle 6 is manually replaced, the image detection mechanism 2 detects and acquires the information of the dispensing position of the replaced needle 6 on the workpiece B to be processed, and the displacement measurement mechanism 3 detects and acquires the height between the replaced needle 6 and the dispensing position of the replaced needle 6 on the workpiece B to be processed, so that the spatial position information of the replaced needle 6 is obtained. Based on the information interaction between the control system 5 and the image detection mechanism 2 and the displacement measurement mechanism 3, the control system 5 receives the spatial position information of the needle 6 before replacement and the spatial position information of the needle 6 after replacement, and calculates the position deviation between the positions of the needle 6 before and after replacement; meanwhile, based on the information interaction between the control system 5 and the position adjusting mechanism 4, the control system 5 controls the position adjusting mechanism 4 to move so as to correct the position of the needle 6 after replacement to the position of the needle 6 before replacement.
Because after the syringe needle 6 is changed manually, the full-automatic syringe needle position self-correction system of this application can carry out the automatic correction to the position of the syringe needle 6 after changing, has greatly reduced the deviation between the syringe needle 6 position before and after the change from this to improve the uniformity of the some glue positions of syringe needle 6 before and after the change, improved the qualification rate after waiting to process work piece B processing from this. In addition, this kind of correction mode of full-automatic syringe needle position self-correction system of this application is simple swift, has greatly reduced the shut down time of trading the needle to help improving production efficiency.
The third direction Z of the workpiece B to be processed is the thickness direction of the workpiece B to be processed, and the first direction X of the workpiece B to be processed, which will be described later, is the length direction or width direction of the workpiece B to be processed, and correspondingly the second direction Y of the workpiece B to be processed is the width direction or length direction of the workpiece B to be processed.
In order to facilitate the calculation of the deviation between the positions of the needle 6 before and after replacement, a three-dimensional coordinate system O-xyz is established by taking the third direction Z of the workpiece B to be processed as the Z axis, the second direction Y as the Y axis and the first direction X as the X axis. The information of the dispensing positions of the needle 6 on the workpiece B to be processed before and after replacement is the corresponding coordinates of the needle 6 on the x axis and the y axis before and after replacement, and the height between the needle 6 before and after replacement and the dispensing position of the needle 6 on the workpiece B to be processed is the coordinate of the needle 6 on the z axis before and after replacement.
In some embodiments, referring to fig. 1 and 2, the needle fixing mechanism 1 comprises a mounting base 11, a positioning barrel 12 and a fastening nut 13. The mount 11 is provided with a mounting hole and a fixing hole. The positioning cylinder 12 is arranged in the mounting hole in a penetrating manner, and the fastening nut 13 is matched with the fixing hole so as to fixedly mount the positioning cylinder 12 in the mounting seat 11. The needle 6 is replaceably mounted to the positioning barrel 12. Specifically, the needle 6 may be mounted to the positioning barrel 12 by a threaded connection.
In some embodiments, with further reference to fig. 2, the mounting base 11 is also provided with a limiting hole. The needle 6 is fixedly connected with one end of the positioning barrel 12 and is inserted into and limited in the limiting hole, so that the needle 6 and the one end of the positioning barrel 12 are fixed; and the other end of the positioning cylinder 12 is fixed in the mounting hole by the fastening nut 13, so that the other end of the positioning cylinder 12 is fixed. Because both ends of the positioning cylinder 12 and the needle 6 are fixed, the stability of the needle 6 during the dispensing operation is ensured, and the qualified rate of the workpiece B to be processed after processing is improved.
In some embodiments, the image detection mechanism 2 includes an industrial camera that detects and acquires information on the dispensing position of the needle 6 on the workpiece B to be processed before and after replacement by image processing.

After the needle 6 is replaced, based on the position deviation of the needle 6 in the third direction Z before and after replacement calculated by the control system 5, the first motor 413 drives the first slider 411 and the needle fixing mechanism 1 to move, so that the replaced needle 6 moves in the third direction Z to the position of the needle 6 in the third direction Z before replacement. In some embodiments, with further reference to FIG. 2, first adjustment assembly 41 also includes a first mounting plate 414, first mounting plate 414 being coupled to second adjustment assembly 42 described below.

The position of the replaced needle head 6 in the first direction X can be corrected by the second adjusting assembly 42 in time, so that the position deviation of the needle head 6 in the first direction X before and after replacement is greatly reduced, the consistency of the dispensing positions of the needle head 6 before and after replacement is improved, and the qualified rate of the workpiece B to be processed after processing is improved.
In some embodiments, with further reference to fig. 3, the second adjustment assembly 42 includes a second slide 421, a second guide rail 422, and a second motor 423.

In some embodiments, with further reference to fig. 3, the second adjustment assembly 42 further includes a second mounting plate 424, the second mounting plate 424 being connected to the third adjustment assembly 43.
