Therefore, during circular dispensing, the distance between the first glue dot and the last glue dot will be different from the distance between the other two adjacent glue dots. With reference to Figure 1, the dispenser moves in a clockwise direction, and the glue point PF is the first glue to be dispensed, and when the glue is dispensed according to the spacing distance corresponding to the preset torque, when the last glue point PL is dispensed Although the distance between the last glue point PL and the previous glue point P is still equal to the interval distance, the distance between the glue point PF and the last glue point PL is not equal to the interval distance.

Referring to FIG. 2, an embodiment of the glue dispensing system 100 of the present invention is configured to be electrically connected to a dot glue graphic editing terminal 200. The dispensing graphics editing terminal 200 is, for example, a personal computer, and is used to generate a dispensing path. The dispensing path can be a straight line, a curved line, a closed graphic, or, for example, a non-closed graphic, and the point can be adjusted according to the needs of the user. The shape of the glue path.

In this embodiment, the dispensing path is described as a circle. The user can set a radius by operating the dispensing graphics editing terminal 200, and specify the glue in the circle drawn by the radius. According to the number of points, the dispensing graphics editing terminal 200 calculates the circumference of the circle according to the radius, and then obtains multiple preset dispensing positions corresponding to the number of glue points based on the circumference and the number of glue points . Furthermore, since the glue dots are evenly distributed according to the arc length of the dispensing path under the condition of a given radius, the coordinates of the glue dots (taking rectangular coordinates as an example) are likely to be infinitely non-circular. Decimals, therefore, in this embodiment, rounding is used to obtain the preset dispensing positions where the smallest unit of coordinates is, for example, 0.1 mm (in other embodiments, the smallest unit may also be 1 mm).

Moreover, after the dispensing pattern editing terminal 200 calculates the preset dispensing positions, the user can set a continuous dispensing start position and a continuous dispensing position by operating the dispensing pattern editing terminal 200 The dispensing end position and the multiple dispensing times corresponding to the preset dispensing positions, and after the user’s setting, the dispensing graphics editing terminal 200 generates the preset dispensing positions, the The glue injection time, the start position of the continuous glue dispensing and the glue data of the end position of the continuous glue dispensing. In this embodiment, the glue injection times can all be the same or different, and the glue injection Glue time refers to the time it takes to inject the viscose into the capsule rather than the time to inject the glue.

In addition, the user can assemble a dispensing pattern by setting multiple dispensing data. And each dispensing data can also include multiple continuous dispensing start positions and multiple continuous dispensing end positions, which are not limited to the above-mentioned one continuous dispensing starting position and one continuous dispensing end position. Note that Yes, the user does not have to set the continuous dispensing start position, the continuous dispensing end position, and the glue injection time, and can selectively set only one or a few of them, or not set them at all, depending on actual application requirements. In the case that the user has not set the continuous dispensing start position and the continuous dispensing end position, the dispensing data generated by the dispensing graphics editing terminal 200 only includes the preset dispensing positions, and will compare You should wait for the time of the preset dispensing position to be set to the preset dispensing time (for example, 1 millisecond).

In addition, after the user sets the start position of continuous dispensing and the end position of continuous dispensing, the dispensing graphics editing terminal 200 will define the boundary between the continuous dispensing start position and the continuous dispensing according to the dispensing path. One or more preset dispensing positions between the end positions are deleted.

In this embodiment, the glue dispensing system 100 includes a mobile device 10, a glue dispensing device 20, and a control device 30 electrically connected to the mobile device 10 and the glue dispensing device 20.

The control device 30 includes, but is not limited to, a digital signal processor (DSP), for example, and is electrically connected to the dispensing pattern editing terminal 200 to receive and store the dots from the dispensing pattern editing terminal 200 Glue information.

After storing the dispensing data, the control device 30 can add and/or delete preset dispensing positions according to a user's operation or a request from the dispensing graphics editing terminal 200, more specifically , The control device 30 can be based on a glue point addition request from the glue dispensing graphic editing terminal 200 and including a new glue dispensing position and a new glue injection time corresponding to the newly added glue position and the glue dispensing Data, in the dispensing data, add the newly-added dispensing position and the newly-added dispensing time, or the control device 30 can edit the terminal 200 according to the dispensing pattern and include the preset dispensing A glue point deletion request of one of the positions and the glue data, in the glue data, remove one of the preset glue positions and the corresponding glue injection time for the user to further fine-tune the glue The location of the point.

The glue dispensing device 20 includes, but is not limited to, a dot glue head (not shown), and is installed on the mobile device 10. The moving device 10 includes, but is not limited to, a three-axis slide rail (not shown), a driving unit 11, a motor unit 12, and an encoder unit 13 for example. The driving unit 11 is controlled by the control device 30 and used to drive the motor unit 12 to move the glue dispensing device 20. When the motor unit 12 is driven by the driving unit 11 to operate, the encoder unit 13 generates a corresponding position code data according to the rotation angle information of the motor unit 12, and periodically transmits the position code data to the control device 30, so that the control device 30 can learn the current position of the glue dispensing device 20 according to the position code data.

Furthermore, the mobile device 10 can move in a one-dimensional, two-dimensional or three-dimensional space. Taking the mobile device 10 moving on a two-dimensional plane as an example, the motor unit 12 of the mobile device 10 includes, but is not limited to, two servo motors (not shown) for controlling the vertical and horizontal directions respectively, and the encoder unit 13 includes Corresponding to the two encoders (not shown in the figure) of the servo motors respectively, the drive unit 11 drives the servo motors to control the dispensing device 20 in the vertical direction (the Y axis on the rectangular coordinates) and the horizontal direction (rectangular coordinates). The position encoding data generated by the encoder unit 13 integrates the encoding data generated by the encoders according to the corresponding servo motors. In other words, if the moving device 10 moves in the three-dimensional space, the motor unit 12 includes three servo motors, and the encoder unit 13 includes three encoders corresponding to the servo motors.

2 and 3, the following describes how the control device 30 of this embodiment controls the mobile device 10 to move along the dispensing path from the dispensing graphics editing terminal 200, and at the same time, according to the dispensing data The glue dispensing procedure is executed, and the glue dispensing procedure includes steps S1 to S9. In this embodiment, the control device 30 controls the mobile device 10 to move and start the glue dispensing procedure at the same time.

First, in step S1, the control device 30 acquires one of the preset dispensing positions included in the dispensing data. More specifically, the preset dispensing positions extend the dispensing path. Sequentially, at the beginning of the execution of the glue dispensing program, the control device 30 obtains the first preset glue dispensing position.

Next, in step S2, the control device 30 determines whether the preset dispensing position is consistent with the continuous dispensing starting position, if yes, then proceed to step S7, if not, then proceed to step S3.

If the judgment result in step S2 indicates that the preset dispensing position does not match the continuous dispensing starting position, the control device 30 then executes step S3,

In step S3, the control device 30 receives the position code data from the mobile device 10 indicating the current position of the glue device 20, and determines the glue device 20 based on the position code data and the moving speed of the mobile device 10 Whether the time required to move from the current position to the preset glue dispensing position is not greater than a glue injection time corresponding to the preset glue dispensing position.

If the judgment result in step S3 indicates that the time required for the dispensing device 20 to move to the preset dispensing position is greater than the dispensing time, the control device 30 continues periodically (in this embodiment, the period For example, it is 0.1 millisecond/time) to repeat step S3 to obtain a new position coding data and make a judgment.

When the judgment result in step S3 indicates that the time required for the dispensing device 20 to move to the preset dispensing position is not greater than the dispensing time, the control device 30 executes step S4 to control the dispensing device 20 to execute The glue injection action in the glue dispensing operation.

More specifically, the glue dispensing operation described in this embodiment essentially covers glue injection and glue spraying. In detail, before the glue is sprayed, the glue dispensing device 20 needs to perform a glue injection action to inject the glue into the capsule. The aforementioned glue injection time is the duration of the glue injection into the capsule. The glue spraying action means that after the glue injection is completed, the glue dispensing device 20 sprays the glue from the capsule.

Incidentally, the length of the glue injection time will affect the amount of glue sprayed when the glue is sprayed. The longer the glue injection time, the more glue will be sprayed, and vice versa. The user can adjust the amount of glue for each glue point by setting the glue injection time of each glue point, so that when actually dispensing, a different amount of glue is given to each glue point according to actual needs. In addition, the glue dispensing device 20 of this embodiment will continue to heat the glue before the glue is injected, so that the glue is in a non-cured state and can be injected into the capsule, and the glue is sprayed on the glue device 20. When glueing, the glue can be ejected from the capsule through high-pressure gas. The above-mentioned heating method and the smooth dispensing of high-pressure gas are conventional techniques and are not the focus of the improvement of this case, so I will not repeat them.

Next, the control device 30 executes step S5 during the glue injection operation of the glue dispensing device 20. The control device 30 receives the position code data from the mobile device 10 indicating the current position of the glue dispensing device 20, and According to the position code data and the preset glue dispensing position, it is determined whether the position of the glue dispensing device 20 matches the preset glue dispensing position.

When the judgment result in step S5 indicates that the position of the glue dispensing device 20 does not conform to the preset glue dispensing position, the control device 30 will continue to periodically acquire new position code data as described above, and again according to the new position code data. The position code data and the preset glue dispensing position determine whether the position of the glue dispensing device 20 matches the preset glue dispensing position.

When the judgment result in step S5 indicates that the position of the dispensing device 20 matches the preset dispensing position, the control device 30 then executes step S6 to control the dispensing device 20 to execute the dispensing operation included in the dispensing operation. The glue spraying action points the glue at the preset glue dispensing position.

For example, if the glue injection time is 2 milliseconds, the control unit will determine in step S3 that the time required for the glue dispensing device 20 to move from the current position to the preset glue position is not more than 2 milliseconds, Control the glue dispensing device 20 to inject glue. In other words, if the moving speed is 0.6 mm/msec, the distance between the current position of the glue dispensing device 20 and the preset glue position does not exceed The glue injection starts at 1.2 mm (2 milliseconds*0.6 mm/millisecond), and when the control device 30 determines that the glue dispensing device 20 has been located at the preset glue dispensing position, the glue dispensing device 20 is controlled to perform the glue spraying action.

After the control device 30 controls the dispensing device 20 to execute the dispensing action, it then executes step S10 to determine whether the current preset dispensing position is the last preset dispensing position in the dispensing data, if so, then The dispensing procedure is ended, if not, step S1 is then executed.

When the judgment result in step S10 indicates that the current preset dispensing position is not the last preset dispensing position, the control device 30 then returns to step S1 to obtain the next preset dispensing position and execute it again In this dispensing procedure, the dispensing is completed until all preset dispensing positions are completed.

It is worth mentioning that in other embodiments, referring to FIG. 4, in step S21, the control device 30 determines the dispensing according to the position code data from the mobile device 10 and the moving speed of the mobile device 10 Whether the time required for the device 20 to move from the current position to the preset glue dispensing position is not greater than a glue injection time corresponding to the preset glue dispensing position (as in step S3 above), and when the judgment result of step S21 indicates The time required for the glue dispensing device 20 to move to the preset glue dispensing position is not greater than the glue injection time, and the control device 30 executes step S22 to control the glue dispensing device 20 to perform the glue injection action in the glue dispensing operation. In this embodiment, after the glue dispensing device 20 completes the glue injection action that lasts for the glue injection time, it directly executes the glue spraying action (step S23), without waiting for the control device 30 to determine the glue in step S5 The position of the glue dispensing device 20 is located at the preset glue dispensing position.

Referring again to FIG. 3, if the judgment result in step S2 indicates that the position of the dispensing device 20 matches the continuous dispensing start position, the control device 30 then executes step S7 to receive a point from the mobile device 10 indicating the point According to the position code data of the current position of the glue device 20, and according to the position code data and the starting position of the continuous glue, it is determined whether the position of the glue device 20 matches the starting position of the continuous glue.

Like the above steps S3 and S4, when the control device 30 determines whether the time required for the dispensing device 20 to move from the current position to the continuous dispensing start position is not greater than the corresponding glue injection time, the control device 30 will The glue dispensing device 20 is controlled to perform the glue injection action, and when the glue dispensing device 20 reaches the starting position of the continuous glue dispensing, the glue dispensing device 20 is controlled to perform the glue spray action.

If the judgment result of step S7 indicates that the position of the dispensing device 20 does not match the starting position of the continuous dispensing, the control device 30 periodically repeats step S7 (at this time, the mobile unit continues to dispense Path movement) to receive the position code data from the mobile device 10, and determine whether the position of the glue dispensing device 20 matches the starting position of the continuous glue dispensing according to the newly acquired position code data.

When the judgment result of step S7 indicates that the position of the dispensing device 20 matches the continuous dispensing starting position, the control device 30 executes step S8 to control the dispensing device 20 to start continuous dispensing. The continuous glue dispensing refers to the glue dispensing device 20 repeatedly performing glue injection and glue spraying actions. That is to say, starting from the position of the dispensing device 20 moving to the starting position of the continuous dispensing, the dispensing device 20 will continue to perform dispensing without the control device 30 determining the current position and position code data To determine whether to dispense glue.

While the dispensing device 20 continues to dispense, the mobile device 10 (and the dispensing device 20) are still advancing along the dispensing path, and at the same time, the control device 30 periodically moves from the mobile device 10 The position code data is received, and step S9 is executed to determine whether the current position of the glue dispensing device 20 matches the continuous glue end position according to the received position code data and the continuous glue dispensing end position.

If the judgment result of step S9 indicates that the position of the dispensing device 20 does not match the continuous dispensing end position, the control device 30 continues to perform step S9, and the dispensing device 20 continues to dispense while judging the point Whether the glue device 20 has reached the continuous dispensing end position, if the judgment result of step S9 indicates that the position of the dispensing device 20 matches the continuous dispensing end position, the control device 30 controls the dispensing device 20 to stop dispensing Glue, and execute step S10 to determine whether the continuous dispensing end position is the last preset dispensing position, if yes, the procedure is ended, if not, step S1 is executed.

That is to say, between the continuous glue dispensing start position and the continuous glue dispensing end position, the glue dispensing device 20 will continuously dispense glue, so as to achieve the effect of improving the bonding effect for the specific part of the glue dispensing path.

In addition, if the dispensing data only includes the continuous dispensing start position but not the continuous dispensing end position, the dispensing device 20 will start from the continuous dispensing start position and continuously dispense to The last preset dispensing position.

With reference to Figure 5, the following example illustrates the above-mentioned glue dispensing procedure. First, the user can first set the continuous glue starting position, the continuous glue ending position, and the glue injection time of each preset glue position. The following table is an example. Continuous glue starting position P' End position of continuous dispensing P" P injection time 1 millisecond P''' injection time 2 milliseconds

After the setting is completed, the control device 30 starts to control the mobile device 10 to move along the dispensing path (Figure 5 takes a circle as an example, and moves clockwise), and obtains the first preset dispensing position PF (step S1), after obtaining the preset dispensing position, determine whether the first preset dispensing position PF is consistent with the continuous dispensing starting position P'(step S2), and after judging that it does not match, it is determined that the dispensing device 20 Whether the time required for the current position to move to the preset dispensing position is not greater than the dispensing time corresponding to the first preset dispensing position PF (step S3), if yes, the control device 30 controls the dispensing device 20 Perform a glue injection action (step S4), and when it is determined that the position of the glue dispensing device 20 is consistent with or similar to the preset glue dispensing position (step S5), control the glue dispensing device 20 to perform a glue spray action (step S6), In order to eject the glue dots at the first preset dispensing position PF.

In the above process, the mobile device 10 continuously moves along the dispensing path, the control device 30, and after completing the dispensing action of the first preset dispensing position PF, the control device 30 continues according to other presets. Set the dispensing position P to execute the above steps S1 to S6, and then, when the control device 30 determines that the preset dispensing position matches the continuous dispensing starting position P'according to the current preset dispensing position P, the control After determining that the position of the dispensing device 20 matches the continuous dispensing start P'position (step S7), the device 30 continuously controls the dispensing device 20 to dispense (step S8) until the dispensing device 20 is determined The position of the device 20 conforms to the continuous dispensing end position P" (step S9). As a result, there will be multiple continuous dots between the continuous dispensing start position P'and the continuous dispensing end position P” Glue point.

Next, the control device 30 obtains the preset glue dispensing position P''', and acquires the glue injection time corresponding to the preset glue dispensing position P''' according to the dispensing data, which is different from the above step S3 However, since the glue injection time corresponding to the preset glue dispensing position P''' is longer than other preset glue dispensing positions P, therefore, the control device 30 will be compared with other preset glue dispensing positions P. Control the glue dispensing device 20 to inject glue in advance, so that more glue can be injected into the capsule, and make the glue dots that the glue dispensing device 20 dispenses when it moves to the preset glue dispensing position P" It is larger than the glue dots located at other preset dispensing positions P. It can be seen from the foregoing that the present invention can be more flexible by setting the continuous dispensing start position P', the continuous dispensing end position P", and the different injection time corresponding to the desired glue dot size. Adjust the amount of glue at each dispensing position. And, after all the glue dots are dispensed, the distance between the glue dot at the first preset dispensing position PF and the glue dot at the last preset dispensing position PL It is also the same (or very close to) the distance between any two adjacent preset dispensing positions P.

In addition, after the dispensing is completed, the control device 30 can increase the amount of glue at a specific dispensing position through a user's operation or a request from the dispensing graphics editing terminal 200. More specifically, the The control device controls the mobile device 10 to move to the glue replenishing position according to a glue replenishment request from the glue dispensing graphic editing terminal 200 and including one of the preset glue positions as a glue replenishing position, and After the position of the glue dispensing device 20 matches the glue replenishing position, the glue dispensing device 20 is controlled to perform a glue dispensing operation to increase the amount of glue at one of the preset glue dispensing positions. In other embodiments, the glue replenishing position It can also be any point that does not fall on the dispensing path.

In particular, according to an embodiment of the present invention, when judging whether the position of the dispensing device 20 matches the preset dispensing position based on the position code data, the control device 30 can be based on the position coding data, The predetermined dispensing position, a first predetermined distance, and a second predetermined distance are generated by first and second judgment results to make a judgment, wherein the first predetermined distance is smaller than the second predetermined distance.

In detail, when judging whether the position of the dispensing device 20 matches the preset dispensing position, the control device 30 will first make a first judgment result, if the first judgment result indicates the position indicated by the position code data The distance between the position and the preset dispensing position is less than the first preset distance, the control device 30 determines that the position of the dispensing device matches the preset dispensing position, and controls the dispensing device 20 to dispense .

If the first judgment result indicates that the distance between the position indicated by the position code data and the preset dispensing position is greater than the first preset distance and not greater than the second preset distance, the control device 30 Acquire again the next position code data from the mobile device 10 and generate a second judgment result.

If the second judgment result indicates that the distance between the position indicated by the next position code data and the preset dispensing position is less than the second preset distance and greater than the first preset distance, or the next position The distance between the position indicated by the code data and the preset dispensing position is less than the first preset distance, then the control device 30 determines that the position of the dispensing device matches the preset dispensing position, and controls the dispensing The device 20 dispenses glue.

In this embodiment, the first predetermined distance is, for example, 0.5 mm, and the second predetermined distance is, for example, 1 mm. If the first judgment result indicates that the current position is within the first preset distance from the preset dispensing position, the control device 30 controls the dispensing device 20 to spray glue. If the first judgment result and the second The judgment results all indicate that the current distance is less than the second preset distance and greater than the first preset distance. Even if the current distance is not less than the first preset distance, the control device 30 still controls the glue dispensing device 20 to spray glue. , Because when the mobile device 10 is constantly moving, if the two consecutive judgment distances are both greater than the first preset distance and less than the second preset distance, it is likely that the dispensing device 20 is moving away from the The glue dispensing position is preset. Therefore, when dispensing glue at this time, the glue dot can still be spotted within the error range without being too far away from the preset glue dispensing position.

In addition, it is judged whether the position of the glue dispensing device 20 conforms to the continuous glue starting position, the continuous glue end position, and the time required to move to the preset glue dispensing position is not greater than the glue injection time At this time, the above-mentioned method can be used to improve the accuracy of the position determination, which will not be repeated here.

In the implementation state where the user does not set the continuous dispensing start position, the continuous dispensing end position, and the glue injection time, as mentioned above, the dispensing data only includes the preset dispensing positions, and the dispensing system 100 When the dispensing process is executed according to the dispensing data and the dispensing path is circular, a plurality of glue dots with substantially the same spacing, uniform size, and circular arrangement as shown in FIG. 6 will be spotted.

To sum up, the dispensing system 100 of the present invention uses the dispensing device 20 to move to the preset dispensing position to dispense to ensure that the dispensing can be performed at each preset dispensing position, so that the In the dispensing system 100 of the embodiment, when the dispensing path is circular, the distance between any two adjacent glue dots can be the same. Furthermore, the control device 30 moves to the preset when the dispensing device 20 is When the time required for the glue dispensing position is not greater than the glue injecting time, the glue dispensing device 20 is controlled to inject glue so that it can spray glue directly when it reaches the preset glue position, thereby improving the efficiency of glue dispensing. The control device 30 controls the glue dispensing device 20 to continuously dispense glue from the continuous glue dispensing start position to the continuous glue dispensing end position, and changes the amount of glue injected into the capsule by the glue dispensing device 20 according to different glue injection times, and then Changing the amount of glue sprayed can more flexibly control the amount of glue in different positions on the dispensing path according to actual needs, so it can indeed achieve the goal of new cost.

However, the above are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
