Description

Slider automatic adjustment device, system and method of use

This invention is applied to the technical field of machine tools, and particularly relates to an automatic adjustment device, system, and method of use capable of quickly adjusting a slide.

It is common knowledge that machine tools with slide motion, such as punch presses and powder metallurgy machines, require the slide to be adjusted to a preset position when installing different molds to facilitate subsequent processing.

To help operators easily identify the current position of the slider and the set upper and lower limits, a slider indicator is installed on the machine. This slider indicator includes a display panel that displays the current relative position of the slider, the upper and lower limits of the slider, and a processor chip and sensors. During initial calibration of the slider, an experienced operator can manually adjust the slider position based on actual conditions, thereby calibrating the slider to the optimal setting, i.e., the optimal operating position, effectively completing the initial calibration process.

However, the aforementioned slider indicators still have their shortcomings. Due to the uncertainty in product manufacturing during the operation, molds may often need to be replaced due to the production schedule. After each mold change, the slider position needs to be recalibrated. Since the parameters of the adjusted molds cannot be recorded, the adjustment time is affected, resulting in wasted processing time.

Furthermore, since the slider position can only be adjusted manually during the calibration process, the calibration time is relatively increased.

The inventors of this invention have discovered that the previously used slider adjustment method still fails to improve adjustment efficiency in actual use, thereby reducing production speed. They have therefore invented this invention to improve it.

The primary objective of this invention is to provide a slider automatic adjustment device, system, and method for use thereof. This device, through automatic adjustment, enables the slider to more accurately and quickly reach a preset set point. Adjusting the slider position in this manner can effectively shorten adjustment time.

A secondary object of the present invention is to provide an automatic slider adjustment device, system, and method of use. By memorizing the parameters of the slider settings required for different molds, the device can increase the efficiency of slider adjustment and significantly shorten the lead time of machining operations.

To achieve the aforementioned objectives, the present invention utilizes a technical approach to provide an automatic slider adjustment device for installation on a machine tool having a slider and a motor for driving the slider's linear movement. The device comprises a slider indicator and a slider controller. The slider indicator comprises a first display panel, a sensor, a first processor chip, a first power source, and a first communication chip. The first power source provides power to the slider indicator. The sensor detects the slider's position, providing the first processor chip with a calculation to display the current value of the slider's corresponding position on the first display panel. The slider controller comprises a housing, a display panel, and a control module. The housing is disposed on one side of the machine tool and has an outer shell. The control module is disposed in the outer shell and is electrically connected to the display panel. The control module includes a power supply, a processor chip, a communication chip, a forward motor relay, a reverse motor relay, and a reverse motor relay. The power supply supplies power to the control module. The processor chip is electrically connected to the display panel, which displays various numerical outputs and messages from the control module. A preset value is input to the processor chip, and by controlling the processor chip to perform calculations, the control module can control the slider to perform corresponding lifting and lowering movements. The communication chip is electrically connected to the first communication chip of the slider indicator, allowing the slider indicator value to be transmitted to the processor chip of the control module via the communication chip for calculation, and then the slider value parameter is displayed on the display panel. The forward motor relay is respectively The processor chip and the machine tool's drive motor are connected to each other, allowing the processor chip to control the motor's forward motion via the forward motor relay. The reverse motor relay is also connected to each of the processor chip and the machine tool's drive motor, allowing the processor chip to control the motor's reverse motion via the reverse motor relay. When in automatic adjustment mode, the forward motor relay and the reverse motor relay cooperate to move the slider to a position corresponding to a set value. The module adjustment switch is also connected to each of the processor chips to control the control module's on/off state.

In one embodiment of the present invention, the above-mentioned automatic slider adjustment device has at least one button exposed on the outer shell, and the control module is electrically connected to the button.

In one embodiment of the present invention, the aforementioned automatic slider adjustment device has a processor chip with language switching, metric/imperial switching, and four-digit or five-digit display switching functions. The displayed digits can control the adjustment accuracy to the micron level.

In one embodiment of the present invention, the processor chip in the aforementioned automatic slider adjustment device has the function of selecting the motor's rotation direction (commonly known in the industry as R-type or L-type switching). This function switches the motor's forward and reverse rotation to correspond to the slider's rise or fall, in accordance with the machine tool's motor gear position.

In one embodiment of the present invention, the aforementioned automatic slider adjustment device includes a control module for the slider controller further comprising a manual forward motor switch and a manual reverse motor switch. The manual forward motor switch is connected to the processor chip and the drive motor of the machine tool, respectively, for manual operation. The processor chip controls the motor to rotate in the forward direction when the motor is driven. The manual reverse motor switch is connected to the processor chip and the machine tool's drive motor, respectively, for manual operation. The processor chip controls the motor to reverse when driven. When in manual adjustment mode, the manual forward motor switch and the manual reverse motor switch cooperate to move the slider to the position corresponding to the set value.

In order to achieve the aforementioned purpose of the invention, the technical means used by the present invention is to provide a slider automatic adjustment system for being installed on a machine tool, wherein the machine tool has a slider and a motor that drives the slider to move linearly, including a processing unit, an automatic adjustment unit, a manual adjustment unit and a change unit. The processing unit is used to calculate and control the motor and is electrically connected to a display panel. A set value is input into the processing unit, corresponding to a preset position of the slider. The automatic adjustment unit is controlled by the processing unit to automatically adjust the position of the machine tool slider to a position corresponding to the set value. The manual adjustment unit is manually controlled by the processing unit to manually adjust the position of the machine tool slider to a position corresponding to the set value. The switching unit controls whether the processing unit is activated.

To achieve the aforementioned objectives, the present invention utilizes a method for using a slider automatic adjustment device. The method utilizes the aforementioned device, including switching the module adjustment switch to the on position to activate the control module, inputting a preset setting value into the slider controller, and controlling the control module to activate the automatic adjustment mode. When the control module activates the automatic adjustment mode, the processor chip controls the operation of the machine tool's drive motor and communicates with the slider indicator via the communication chip. The first communication chip transmits information to compare the slider's position with the set value. When the slider's current value approaches the set value, the processor chip controls the drive motor to stop. The processor chip then controls the forward motor relay or the reverse motor relay to intermittently and slowly control the drive motor, fine-tuning the slider's position until the slider moves to the preset position corresponding to the set value, as configured by the slider controller. The control module is then shut down by controlling the module's adjustment switch to switch off.

In one embodiment of the present invention, a method for using the aforementioned automatic slider adjustment device is provided. After the slider has been moved to the set value, if the set value still deviates from the desired position, the user can adjust the set value input by the slider controller using the aforementioned method. This process is repeated until the slider is moved to the optimal position corresponding to the set value.

In order to achieve the aforementioned purpose of the invention, the technical means used by the present invention is to provide a method for using a slider automatic adjustment device. The method uses the above-mentioned device, including switching the module adjustment switch to start to start the control module, and inputting the preset setting value into the slider controller in advance. The user can control the manual forward motor switch or the manual reverse motor switch by long pressing or short pressing through visual means, and long pressing the manual forward motor switch or the manual reverse motor switch. The manual forward motor switch or the manual reverse motor switch continuously controls the forward or reverse movement of the machine tool's drive motor via the processor chip, thereby continuously moving the slider up or down. Similarly, a short press of the manual forward motor switch or the manual reverse motor switch intermittently controls the slider to move to the position corresponding to the set value. The control module is then turned off by switching the module adjustment switch to off.

In one embodiment of the present invention, the aforementioned automatic slider adjustment device employs a method in which, when the slider moves to the position corresponding to the optimal setting, the processor chip is controlled to record the corresponding value, i.e., the setting value corresponding to this calibration. Later, as needed, the recorded setting value in the processor chip can be retrieved to directly adjust the slider.

Figure 1 is a schematic diagram of an embodiment of the present invention.

Figure 2 is a system block diagram of the slider indicator of the present invention.

Figure 3 is a system block diagram of the slider controller of the present invention.

As shown in Figures 1 to 3, the automatic slider adjustment device of the present invention is used to be connected to a machine tool (not shown).

The machine tool includes a drive motor (not shown) to drive a slider (not shown) to move vertically.

The slider automatic adjustment device of the present invention includes a slider indicator 10 and a slider controller 20.

The slider indicator 10 comprises a first display panel 11, a sensing element 12, a first processor chip 13, a first power source 14, and a first communication chip 15. The first power source 14 provides power to the slider indicator 10, and the sensing element 12 can sense the slider's movement. The sensing element 12 can be selected from a sensor, preferably an angle sensor with a speedometer and tilt angle sensing module. The sensing element 12 is provided to the first processor chip 13 for calculation, and the slider's current value 110, an upper limit value 111, and a lower limit value 112 are displayed on the first display panel 11.

The slider controller 20 of the present invention comprises a housing 21, a display panel 22, and a control module 23.

The housing 21 is disposed on one side of the machine tool and has an outer shell 210 and at least one button 211 or knob 212 exposed from the outer shell 210.

The control module 23 is disposed within the housing 210 and includes a power supply 230, a processor chip 231, a communication chip 232, a forward motor relay 233, a reverse motor relay 234, a module adjustment switch 235, a manual forward motor switch 236, and a manual reverse motor switch 237.

The power supply 230 supplies power to the control module 23.

The processor chip 231 is electrically connected to the display panel 22 and the button 211 of the housing 21. The display panel 22 is used to display various numerical outputs and messages provided by the control module 23, such as the current value 110, upper limit 111, and lower limit 112 of the slider, as well as the corresponding functions of the button 211 and the knob 212.

In other embodiments, the display panel 22 may be a touch display panel, and the button 211 may be directly displayed on the touch display panel.

In this embodiment, the button 211 is used to control the processor chip 231 to perform calculations and switch various functions. The processor chip 231 inputs a set value (not shown) via the button 211. The set value is the slider required to move to the optimal processing position of the mold for the processor chip 231 to perform calculations, which facilitates the subsequent control of various actions of the slider. In addition, the processor chip 231 has language switching, metric and imperial switching, and a four-digit display (i.e., the accuracy can be set to millimeters). ) or five-digit (i.e., precision can be set down to microns) switching. Furthermore, the processor chip 231 also features direction switching (commonly known in the industry as R-type or L-type switching). This allows for the motor gear of the machine tool to be positioned on the left or right side. This means that different machine tools may produce different forward and reverse rotations corresponding to different slider movements. The processor chip 231 of this embodiment features selective direction switching, enabling it to switch to the desired direction based on the operator's needs.

The communication chip 232 is used to electrically connect to the first communication chip 15 of the slider indicator 10, allowing the slider indicator 10's value to be transmitted via the communication chip 232 to the processor chip 231 of the control module 23 for calculation, and then the slider value parameter is displayed via the display panel 22.

The forward motor relay 233 is connected to the processor chip 231 and the drive motor of the machine tool, respectively, so that the processor chip 231 controls the motor via the forward motor relay 233 to achieve forward motion when driven.

The reverse motor relay 234 is connected to the processor chip 231 and the machine tool's drive motor, respectively. The processor chip 231 controls the motor via the reverse motor relay 234 to cause reverse motion when driven. The forward motor relay 233 and the reverse motor relay 234 work together to move the slider to the position corresponding to the set value.

The module adjustment switch 235 is connected to the processor chip 231 to control the control module 23 to be on or off.

The manual forward motor switch 236 is connected to the processor chip 231 and the machine tool's drive motor, respectively, to allow for manual control of the manual forward motor switch 236. The processor chip 231 controls the motor to rotate forward when driven.

The manual reverse motor switch 237 is connected to the processor chip 231 and the machine tool's drive motor, allowing for manual control of the manual reverse motor switch 237. The processor chip 231 controls the motor to reverse when driven. The manual forward motor switch 236 and the manual reverse motor switch 237 cooperate to move the slider to the position corresponding to the set value.

As shown in Figures 1 to 3, the slider automatic adjustment system of the present invention includes:

A processing unit A is used for computational control and is electrically connected to a display panel 22. A setting value (not shown) is input into the processing unit A. This setting value is the desired position for the slider to move to.

An automatic adjustment unit B, controlled by the processing unit A, is used to automatically adjust the position of the slider of the machine tool to move the slider to the position corresponding to the set value.

A manual adjustment unit C manually controls the processing unit A to manually adjust the position of the slider of the machine tool to move the slider to the position corresponding to the set value.

All switching units D control whether the processing unit A is started.

As shown in Figures 1 to 3, when the automatic slider adjustment device of this embodiment is used to calibrate the slider of the machine tool, the method for using the automatic slider adjustment includes:

Switch the module adjustment switch 235 to start to activate the control module 23.

A preset setting value (not shown) is input into the slider controller 20 in advance. This setting value is the value at which the slider needs to move to the optimal processing position.

When the control module 23 activates the automatic adjustment mode, for example, via the button 211 or the knob 212, the processor chip 231 controls the machine tool's drive motor. The processor chip 231 transmits information to the first communication chip 15 of the slider indicator 10 via the communication chip 232 to compare the slider's current value 110 with the set value. When the slider approaches the set value, the processor chip 231 stops the drive motor.

The processor chip 231 then controls the forward motor relay 233 or the reverse motor relay 234 to intermittently and slowly control the drive motor, fine-tuning the slider position until the slider reaches the desired setting value set by the slider controller 20, thereby moving the slider to the position corresponding to the setting value. Furthermore, if the machine operator mistakenly inputs a value greater than the upper limit 111 or lower limit 112 allowed by the slider, the processor chip 231 controls the forward motor relay 233 or the reverse motor relay 234 to disable the drive motor, effectively preventing damage to the machine caused by improper operation.

If the preset setting value still has an error relative to the actual desired position, the user can adjust the setting value input by the slider indicator 10 using the above method, repeatedly adjusting the slider to the optimal position corresponding to the setting value.

When the control module 23 is controlled to activate the manual adjustment mode, for example, the control is performed via the button 211 or the knob 212.

At this point, the user can visually control the manual forward motor switch 236 or the manual reverse motor switch 237 by long pressing or short pressing. Long pressing the manual forward motor switch 236 or the manual reverse motor switch 237 continuously controls the machine tool's drive motor to move forward or reverse via the processor chip 231, thereby continuously moving the slider up or down. Similarly, short pressing the manual forward motor switch 236 or the manual reverse motor switch 237 intermittently controls the slider to move to the optimal position corresponding to the set value.

When the slider moves to the position corresponding to the optimal setting value, it can control the processor chip 231 to record the relevant value, that is, record the setting value corresponding to this calibration.

In the future, when using the same mold, the set value recorded in the processor chip 231 can be retrieved and the slider can be adjusted directly, which can significantly reduce adjustment time and, in turn, manufacturing time.

When the set value is calibrated, the module adjustment switch 235 can be switched to off to shut down the control module 23, thereby preventing malfunction during subsequent machining operations and providing a protective effect.

The present invention has been described through the above-mentioned embodiments and variations. All embodiments and variations of the present invention are merely illustrative. Based on the essential spirit and scope of the present invention, various variations of the automatic slider adjustment device, system, and method of use that include the above-mentioned features are encompassed by the present invention.
