Description
Technical Field
The present invention relates to a lock state prompting system, a lock state prompting method and a processing machine, and more particularly to a lock state prompting system, a lock state prompting method and a processing machine suitable for a screw lock.
Background
Generally, various components on a circuit board are fixed to the circuit board by screws. In addition, in order to increase the processing efficiency and save the labor cost, most of the screws are locked on the circuit board by matching the processing machine and the electric screwdriver. Specifically, the processing machine is used for carrying and conveying the circuit board, and after the processing machine conveys the circuit board to a specific position, the controller can control the electric screw driver to lock the screw on the screw hole on the circuit board.
However, the screws may not be locked by the electric driver due to the misalignment between the screws and the screw holes on the circuit board. Moreover, if the operator cannot know the situation of the screw not locked from the processing machine, it will take a lot of time and manpower to review the locked state of the screw. Therefore, it is necessary for the technician to provide a technique for detecting the screw locking state in real time and issuing a warning according to the screw locking state.
Disclosure of Invention
The present invention provides a locking state prompting system, a locking state prompting method and a processing machine, which can detect the locking state of a screw in real time and send out a warning according to the locking state of the screw.
The locking state prompting system provided by an embodiment of the invention is used for detecting and prompting whether a locking piece is in a locking state or not, and comprises a locking device, at least one sensor, a controller and an output device. The locking device is used for locking the locking piece. The at least one sensor is electrically connected to the locking device and senses at least one locking data of the locking device. The controller is electrically connected to the locking device and the at least one sensor. The output device is electrically connected to the controller. The controller is used for comparing at least one locking data and at least one reference value to judge whether the locking piece is in a locking state. When the controller judges that the locking piece is not in the locking state, the controller controls the output device to output a warning signal.
In another embodiment of the present invention, a locking state prompting method for detecting and prompting whether a locking member is in a locking state includes the following steps: sensing at least one locking data of a locking device for locking the locking member by at least one sensor; comparing at least one locking data and at least one reference value by a controller to judge whether the locking piece is in a locking state; when the controller judges that the locking piece is not in the locking state, the controller controls an output device to output a warning signal.
In another embodiment of the present invention, a processing machine for carrying a workpiece with a locking member and electrically connecting to a locking status indication system includes a base, a carrying base, a controller, and a telescopic cylinder. The bearing seat is movably arranged on the base and is used for bearing a workpiece provided with a locking piece. The controller is arranged on the base and is used for being electrically connected with the locking state prompting system. The telescopic cylinder comprises a driving part and a movable part. The movable part is movably arranged on the driving part and is provided with a stopping position and an abdicating position. The driving part is fixed on the base and electrically connected with the controller. When the movable part is located at the stopping position, the movable part is stopped at one side of the bearing seat. When the movable part is at the abdicating position, the movable part is far away from the bearing seat. The controller is used for controlling the driving part according to the locking data sensed by the comparing and locking state prompting system and a reference value, so that the movable part moves between the stop position and the yielding position, and the locking state prompting system judges whether the locking piece is in a locking state according to the locking data.
According to the locking state prompting system and the locking state prompting method provided by the embodiment, the controller compares the locking data with the reference value to judge whether the locking piece is in the locking state, and controls the output device to output the warning signal when the locking piece is judged not to be in the locking state. Therefore, the operator can immediately receive the warning when the screw is not locked. Therefore, a large amount of labor and time are not required to be consumed for checking the locking state of the screw.
In addition, according to the processing machine provided by the above embodiment, since the controller controls the driving portion according to the comparison between the locking data and the reference value, the controller moves the movable portion between the stopping position and the yielding position according to whether the locking member is in the locking state. Therefore, the movable part can stop the circuit board with the screw not locked, and further prevent the circuit board with the screw not locked from entering the subsequent processing stage due to carelessness of an operator.
The foregoing description of the present disclosure and the following description of the embodiments are provided to illustrate and explain the principles of the present disclosure and to provide further explanation of the scope of the invention as claimed.

Detailed Description
The detailed features and advantages of the present invention are described in detail in the following embodiments, which are sufficient for anyone skilled in the art to understand the technical content of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by anyone skilled in the art according to the contents, claims and drawings provided in the present specification. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.
Please refer to fig. 1. Fig. 1 is a block diagram of a locking status prompting system according to an embodiment of the present invention.
The locking state prompting system 10 is used for detecting and prompting whether a locking piece is in a locking state according to the locking data. In the present embodiment, the locking member is, for example, a screw, and the locking data is, for example, a torque value and a locking time.
In the present embodiment, the lock status indication system 10 includes a locking device 100, a torque sensor 200, a timer 250, a first controller 300, an output device 400 and a counter 500.
The locking device 100 is, for example, an electric screwdriver for locking the locking member.
In the present embodiment, the torque sensor 200 is electrically connected to the locking device 100 to sense the torque value of the locking device 100. In the present embodiment, the timer 250 is electrically connected to the locking device 100 to sense the locking time of the locking device 100. It should be noted that the torque value sensed by the torque sensor 200 and the locking time sensed by the timer 250 are the locking data of the locking device 100.
The first controller 300 is electrically connected to the locking device 100, the torque sensor 200, the timer 250, the output device 400 and the counter 500.
For example, the output device 400 is a display, an audio device, or a warning light, which can send out a warning signal.
The counter 500 stores a count value indicating the number of the locking members in the locked state.
Referring to fig. 1 and fig. 2, fig. 2 is a flowchart illustrating a locking state prompting method according to an embodiment of the present invention.
The following describes a lock status prompting method performed by the lock status prompting system 10.
First, in step S201, the first controller 300 uses the torque sensor 200 to sense the torque value of the locking member through the locking device 100.
Next, step S202 is executed, and the first controller 300 determines whether the locking member is in the locking state according to the sensed torque value. In detail, the first controller 300 compares the torque value with a first reference value. When the torque value is lower than the first reference value, the first controller 300 determines that the locking member is in the non-locking state; when the torque value is equal to or higher than the first reference value, the first controller 300 determines that the locking member is in the locked state.
Further, if the first controller 300 determines that the locking member is not in the locking state, the first controller 300 executes step S203 to control the output device 400 to output a warning signal. If the first controller 300 determines that the locking member is in the locked state, the first controller 300 continues to perform step S204 to sense the locking time of the locking member by the timer 250 through the locking apparatus 100.
Next, step S205 is executed, and the first controller 300 determines whether the locking member is in the locking state according to the sensed locking time. In detail, the first controller 300 compares the locking time with a second reference value. When the locking time is lower than the second reference value, the first controller 300 may determine that the locking member is not in the locking state; when the locking time is higher than the second reference value, the first controller 300 determines that the locking member is in the locking state.
Further, if the first controller 300 determines that the locking member is not in the locking state, the first controller 300 executes step S206 to control the output device 400 to output the warning signal. If the first controller 300 determines that the locking member is in the locking state, the first controller 300 will continue to execute step S207.
In step S207, the first controller 300 updates the count value stored in the counter 500 and provides the updated count value to the output device for output.
However, the present invention is not limited to using the locking data (i.e. the torque value and the locking time) detected by the torque sensor and the timer to determine whether the locking member is in the locked state. In other embodiments, the locking status notification system may only include the torque sensor and not the timer, and only use the locking data (i.e. the torque value) sensed by the torque sensor to determine whether the locking member is in the locking status. In other embodiments, the locking state prompting system may also include a position sensor instead of the torque sensor and the timer, and determine whether the locking member is in the locking state according to the locking data sensed by the position sensor, where the locking data sensed by the position sensor is, for example, the position data of the locking member.
In addition, in other embodiments, the lock status indication system may not need to include a counter, and the lock status indication method may not need to include the step S207 of updating the count value.
Referring to fig. 3 and 4, fig. 3 is a side view of a movable portion of a telescopic cylinder of a processing machine provided in an embodiment of the invention at a stop position, and fig. 4 is a side view of the movable portion of the telescopic cylinder of the processing machine provided in an embodiment of the invention at an abduction position.
The processing machine 30 is configured to carry a workpiece 50 having a locking member 40, and is configured to be electrically connected to the locking state indicating system, wherein the locking member 40 is, for example, a screw, and the workpiece 50 is, for example, a circuit board. The processing machine 30 includes a base 300, a supporting base 310, a second controller 320, and a telescopic cylinder 330.
The carrier 310 is movably disposed on the base 300 and is used for carrying the workpiece 50 with the locking member 40.
The second controller 320 is disposed on the base 300 and electrically connected to the locking state indicating system.
The telescopic cylinder 330 includes a driving portion 3300 and a movable portion 3301. The movable portion 3301 is movably disposed on the driving portion 3300 and has a stopping position and an avoiding position. The driving unit 3300 is fixed to the base 300 and electrically connected to the second controller 320.
The second controller 320 is used for controlling the driving part 3300 according to the locking data and the reference value sensed by the comparative locking state prompting system, so that the movable part 3301 moves between the stop position and the yielding position. The locking data sensed by the locking state prompting system are, for example, a torque value and a locking time, and the reference values are, for example, a first reference value and a second reference value.
Specifically, as shown in fig. 3, when the second controller 320 determines that the locking member 40 is not in the locking state, the second controller 320 moves the movable portion 3301 to the stop position. In this way, the movable portion 3301 will stop at one side of the carrying seat 310, and block the workpiece 50 with the locking element 40 from advancing in the forward direction D.
As shown in fig. 4, when the second controller 320 determines that the locking member 40 is in the locking state, the second controller 320 moves the movable portion 3301 to the yielding position. In this way, the movable portion 3301 is separated from the carrying seat 310, so that the workpiece 50 with the locking member 40 can advance in the advancing direction D.
According to the locking state prompting system and the locking state prompting method provided by the embodiment, the controller compares the locking data with the reference value to judge whether the locking piece is in the locking state, and controls the output device to output the warning signal when the locking piece is judged not to be in the locking state. Therefore, the operator can immediately receive the warning when the screw is not locked. Therefore, a large amount of labor and time are not required to be consumed for checking the locking state of the screw.
In addition, according to the processing machine provided by the above embodiment, since the controller controls the driving portion according to the comparison between the locking data and the reference value, the controller moves the movable portion between the stopping position and the yielding position according to whether the locking member is in the locking state. Therefore, the movable part can stop the circuit board with the screw not locked, and further prevent the circuit board with the screw not locked from entering the subsequent processing stage due to carelessness of an operator.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
