Detailed Description
The invention will be further described with reference to the accompanying drawings and the detailed description below:
as shown in fig. 1-8, a high precision dispensing apparatus includes a machine body 10, a dispensing assembly 30 and a detecting assembly, wherein the dispensing assembly 30 and the detecting assembly are both mounted on the machine body 10. The dispensing assembly 30 includes a needle 31 and a needle driving mechanism, and the needle 31 can move along the X-axis direction, the Y-axis direction and the Z-axis direction under the driving of the needle driving mechanism.
In addition, the detection assembly comprises a weighing platform 20 and a weighing sensor, the weighing sensor is arranged at the bottom end of the weighing platform 20, and the weighing platform 20 is positioned on the motion track of the rubber needle 31. The weighing platform 20 can receive the glue solution of the glue needle 31; the weighing sensor is used for detecting the weight of the glue solution on the weighing platform 20 and transmitting a weight signal; the rubber needle driving mechanism can drive the rubber needle 31 to move according to the weight signal.
The calibration assembly 50 includes a calibration platform 51, an X-axis calibrator, a Y-axis calibrator and a Z-axis calibrator, and the X-axis calibrator is specifically configured to calibrate the glue needle 31 in the X-axis direction; the Y-axis calibrator is used for calibrating the glue needle 31 in the Y-axis direction. The Z-axis calibrator is disposed on the calibration platform 51, and is configured to calibrate the Z-axis direction of the glue needle 31.
On the basis of the structure, when the high-precision dispensing device is used, the weight of the glue solution with the preset dispensing time can be preset in the control system of the machine body 10, before dispensing, the glue needle driving mechanism drives the glue needle 31 to move to the weighing platform 20 in the X-axis direction and the Y-axis direction, then the glue needle driving mechanism drives the glue needle 31 to move along the Z-axis direction, namely to move up and down, so that the dispensing height is adjusted, the glue needle 31 is dispensed to the weighing platform 20 in the dispensing time, the weighing sensor can detect the change of the glue solution of the weighing platform 20, and a weight signal is transmitted to the control system of the machine body 10.
When the weight signal detected by the weighing sensor is the same as the preset weight of the glue solution or has a slight difference, it indicates that the glue needle 31 is not affected. At this time, the glue needle driving mechanism can drive the glue needle 31 to move to the workpiece position in the X-axis direction and the Y-axis direction, and the glue needle driving mechanism can drive the glue needle 31 to move in the Z-axis direction, so that the glue dispensing height can be adjusted to complete the glue dispensing.
However, when the weight signal detected by the weighing sensor is greatly different from the preset weight of the glue solution, it indicates that the glue needle 31 is contaminated by the residual glue, and the glue cleaning operation needs to be performed at this time, so that the glue needle driving mechanism can drive the glue needle 31 to move to the position of the glue cleaning mechanism in the X-axis direction and the Y-axis direction to perform the glue cleaning operation.
After dispensing is completed, the glue needle driving mechanism can drive the glue needle 31 to move to the weighing platform 20, the glue needle 31 dispenses glue to the weighing platform 20, the weight of the glue dispensed on the weighing platform 20 is unchanged under the condition that the dispensing time is fixed every time, if the weight is changed, whether the glue is polluted or not is indicated, the glue needle 31 needs to be cleaned, and therefore the cleanliness of the glue needle 31 can be detected in real time, and the dispensing quality is improved.
In addition, before and after dispensing, the adhesive needle 31 is driven by the adhesive needle driving mechanism to move to the calibration platform 51, and is calibrated under the action of the X-axis calibrator, the Y-axis calibrator and the Z-axis calibrator respectively, so that the adhesive can be automatically calibrated before and after dispensing each time, and the dispensing precision is improved.
It should be noted that, since the contamination of the glue needle 31 is detected before and after each dispensing operation, the dispensing glue solution can be prevented from being contaminated, and the dispensing quality and the dispensing precision can be controlled according to the contamination of the glue needle 31. Meanwhile, in cooperation with the calibration of the glue needle 31 in the X-axis direction, the Y-axis direction and the Z-axis direction, the trajectory of each movement of the glue needle 31 is relatively stable, and the deviation of the dispensing position is reduced, so that the dispensing quality and the dispensing precision can be controlled from the position precision of the glue needle 31.
Furthermore, the two dispensing assemblies 30 may be provided in two sets, and the two dispensing assemblies 30 may be spaced apart from each other in the X-axis direction, so that the two dispensing assemblies 30 may alternately perform dispensing operation. On the basis of the structure, the detection assembly further comprises a weighing platform driving mechanism, and the weighing platform driving mechanism is used for driving the weighing platform 20 to move along the X-axis direction.
Of course, in the case that the dispensing assembly 30 is provided with two sets, the calibration assemblies 50 may also be provided with two sets, and the two corresponding sets of calibration assemblies 50 may calibrate the glue needles 31 of the two dispensing assemblies 30.
Therefore, the weighing platform 20 can be driven by the weighing platform driving mechanism to be transported to one group of dispensing assemblies 30 along the X-axis direction, the corresponding glue needle driving mechanism in the group of dispensing assemblies 30 can drive the glue needle 31 to move to the weighing platform 20 for weighing, and after weighing is completed, the dispensing driving mechanism can drive the workpiece to be dispensed. At this time, the weighing platform driving mechanism can drive the weighing platform 20 to move to another group of dispensing assemblies 30, and when the previous group of dispensing assemblies 30 performs dispensing operation, the other group of dispensing assemblies 30 can perform contamination detection of the glue needles 31 to prepare for dispensing. The dispensing and the detection of the glue needle 31 are performed alternately in such a reciprocating way, so that the efficiency is improved.
More specifically, the driving mechanism of the weighing platform may include a synchronous motor, a synchronous belt and two synchronous wheels, wherein the two synchronous wheels are distributed at intervals in the X-axis direction and are all pivoted to the machine body 10 through the synchronous wheels. The synchronous belt is synchronously wound outside the two synchronous wheels, and a rotating shaft of the synchronous motor is connected with one of the two synchronous wheels; the weighing platform 20 is fixed with the horizontal conveying section of the synchronous belt.
When the weighing platform 20 is driven to move, the synchronous motor can be started, the synchronous motor drives one of the synchronous wheels to rotate, the other synchronous wheel can rotate under the transmission action of the synchronous belt, the synchronous belt is positioned between the two synchronous wheels and can transmit the horizontal transmission section, the weighing platform 20 is driven to move in the X-axis direction, and the weighing platform 20 can be driven to reciprocate by the forward rotation or the reverse rotation of the synchronous motor.
Of course, the weighing platform driving mechanism can be replaced by a screw rod transmission mechanism or other linear motion output mechanisms such as an air cylinder in the prior art.
Further, a slide rail 11 may be disposed on the machine body 10, the slide rail 11 extends along the X-axis direction, and a slide block is correspondingly disposed on the weighing platform 20, and the slide block is in sliding fit with the slide rail 11. When the weighing platform 20 moves along the X-axis direction, the sliding block is slidably engaged with the sliding rail 11 to guide the weighing platform 20 to move stably.
Further, in this embodiment, the glue needle driving mechanism includes a first electric sliding table 321, a second electric sliding table 322, and a third electric sliding table 323, the first electric sliding table 321 is installed on the machine body 10, and the first electric sliding table 321 is disposed along the Y-axis direction.

The third electric sliding table 323 is mounted on the sliding table of the second electric sliding table 322, and the third electric sliding table 323 is arranged along the Z-axis direction. The glue needle 31 is mounted on the slide table of the third electric slide table 323.
Therefore, the first electric sliding table 321, the second electric sliding table 322 and the third electric sliding table 323 can respectively drive the rubber needle 31 to move in the X-axis direction, the Y-axis direction and the Z-axis direction, the electric sliding table can be directly purchased from the existing market, the specific structure and the working principle of the electric sliding table do not belong to the technical content to be protected in the present application, and those skilled in the art can directly know the electric sliding table from the prior art, which is not described in detail herein. Of course, the rubber needle driving mechanism can be realized by a multi-axis robot in the prior art.
Further, the dispensing assembly 30 further includes a dispensing frame 33 and a height detector 34, the height detector 34 is used for checking the height of the glue pin 31, and the height detector 34 and the glue pin 31 are both mounted on the dispensing frame 33. Therefore, the glue pin driving mechanism can drive the glue dispensing frame 33 to move, and further drive the height detector 34 and the glue pin 31 on the glue dispensing frame 33 to move, when the glue dispensing frame 33 moves to the position above the workpiece or the weighing platform 20, the height detector 34 can determine the vertical height of the glue dispensing position, and further determine the glue dispensing height of the glue pin 31. The specific height detector 34 can be a laser height detector 34 in the prior art, and the glue dispensing efficiency is further improved by utilizing the characteristics of high reaction speed and accuracy of the laser height detector 34.
In this embodiment, the X-axis collimator is a first grating switch 52, and an optical path of the first grating switch 52 extends along the X-axis direction; the rubber needle driving mechanism is used for driving the rubber needle 31 to enter the first grating switch 52 along the Y-axis direction so as to block the light path of the first grating switch 52.
When the detection of the X-axis direction is carried out, the adhesive needle 31 can be driven by the adhesive needle driving mechanism to enter the first grating switch 52 along the Y-axis direction, if the light path of the first grating switch 52 is blocked, the first grating switch 52 can transmit signals in time, it is indicated that the adhesive needle 31 does not deviate in the X-axis direction, and if the light path of the first grating switch 52 is not blocked in time or signal feedback occurs, it is indicated that the adhesive needle 31 deviates, and the feedback cannot be obtained in time under the original fixed route. Therefore, the rubber needle driving mechanism can be adjusted according to the feedback signal.
Similarly, the Y-axis calibrator is a second grating switch 53, and the optical path of the second grating switch 53 extends along the Y-axis direction; the glue needle driving mechanism is used for driving the glue needle 31 to enter the second grating switch 53 along the X-axis direction so as to block the light path of the second grating switch 53.

Therefore, the rubber needle driving mechanism can be adjusted according to the feedback signal.
Further, the Z-axis calibrator is a micro switch 54, the micro switch 54 is disposed below the calibration platform 51, and the specific glue needle driving mechanism can drive the glue needle 31 to press the calibration platform 51 downwards along the Z-axis direction, so as to trigger the micro switch 54.
Therefore, when the calibration is performed in the Z-axis direction, the plastic pin 31 can be driven by the plastic pin driving mechanism to press downwards on the calibration platform 51 along the Z-axis direction, and if the plastic pin 31 does not deflect in the Z-axis direction, that is, the verticality remains unchanged, the point of pressing down the plastic pin 31 each time can touch the micro switch 54. If the micro switch 54 is not touched or the reaction is not timely, it indicates that the deviation occurs, and the rubber needle driving mechanism drives the rubber needle 31 to adjust.
The glue needle 31 can be adjusted back and forth, left and right, and up and down according to the offset, so that the glue needle 31 can perform glue dispensing on a relatively unchanged track. Of course, the grating switch may be replaced by a laser sensor or an infrared sensor.
Further, the calibration assembly 50 may further include an adjusting mechanism, and the adjusting mechanism is configured to adjust an included angle formed between the end surface of the calibration platform 51 and the horizontal plane, that is, when performing the calibration in the Z-axis direction, the included angle formed between the end surface of the calibration platform 51 and the horizontal plane is 00And the calibration platform 51 is parallel to the horizontal plane, and the rubber needle 31 is vertically pressed down to perform calibration. When the included angle between the end surface of the calibration platform 51 and the horizontal plane is large, the calibration platform 51 is not horizontal any more, and at this time, the adjustment can be performed through the adjusting mechanism.
Specifically, the adjusting mechanism includes three adjusting bolts 55, and the three adjusting bolts 55 are screwed on the machine body 10; the top end of the adjusting bolt abuts against the bottom end face of the calibration platform 51; three adjusting bolt is around calibration platform 51's central axis circumference interval distribution, so, accessible adjusting bolt's rotation, adjustment adjusting bolt's up-and-down motion can upwards push up calibration platform 51's bottom, and three adjusting bolt 55's top bears calibration platform 51 jointly, and up-and-down motion alright makes calibration platform 51's terminal surface obtain the adjustment.

The specific discharging mechanism 41 can roll the clear adhesive tape, the traction mechanism is used for providing traction force, and the clear adhesive tape can sequentially pass through the guide mechanism 42, the clamping mechanism 43 and the guide mechanism 42 under the action of the traction force.
In addition, the clamping mechanism 43 may include two first clamping blocks 431, two second clamping blocks 433, a first clamping block driving part 432, and a second clamping block driving part 434, where the two first clamping blocks 431 are distributed at intervals in the X-axis direction, the two second clamping blocks 433 are distributed at intervals in the Y-axis direction, the first clamping block driving part 432 may drive the two first clamping blocks 431 to approach to each other or to be away from each other, and the second clamping block driving part 434 may drive the two second clamping blocks 433 to approach to each other or to be away from each other.
So, after glue needle 31 point was glued to weighing platform 20 on, weighing platform 20 weighed the glue solution, and weight takes place great change, and glue needle 31 receives the pollution promptly, and glue needle actuating mechanism can receive above-mentioned weight signal this moment, drives glue needle 31 and moves to fixture 43 department, and fixture 43 alright centre gripping glue needle 31.
