Description

Smart handheld tool

The present invention relates to a hand-held tool, especially a hand-held tool with a warning function.

When using an electric screwdriver or wrench to perform the locking operation, the user generally only operates according to predetermined processing conditions. For example, the processing conditions include locking the screws in sequence, each screw must be installed according to the torque/angle required by the design, and there are no problems such as missing screws and locking defects at the end of the work cycle. Although some of the aforementioned problems can be improved by using standard operating procedures (SOP) for processing quality verification, torque adjustable tools, and manual marking inspections. However, the aforementioned methods depend on the active execution of the operator, but in practice, it is often difficult to perform effectively due to human negligence, such as missing locks, not locking properly (the torque is not reached/unlocked to the end), or not being locked in sequence. , so that the abnormal product will still flow out.

In view of the problems in the prior art, one objective of the present invention is to provide a smart hand-held tool, which can judge the movement trajectory of the smart hand-held tool and issue a warning according to the situation, thereby preventing abnormal product from flowing out.

A smart hand-held tool according to the present invention includes a hand-held body, a processing mechanism, a trajectory detection module, a control module and a warning module. The processing mechanism is exposed on the handheld body. The track detection module is arranged on the handheld body. The control module is disposed on the handheld body and is electrically connected to the trajectory detection module. The control module determines, through the trajectory detection module, trajectory data of a plurality of processing positions of the processing mechanism in time sequence during processing. The warning module is disposed on the handheld body and is electrically connected with the control module. The warning module generates a warning message according to the result of the control module judging the trajectory data of the processing mechanism. Thereby, the smart hand-held tool can actively generate a warning effect when the trajectory data of the processing mechanism does not meet expectations. In practice, the processed objects can be properly disposed of according to the warning message, such as rework, scrapping, etc., so as to avoid the outflow of abnormal products and solve the problems of the prior art.

The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings.

Please refer to Figure 1 and Figure 2. According to an embodiment of the present invention, a smart handheld tool 1 includes a handheld body 12 and a processing mechanism 14 , and the processing mechanism 14 is exposed on the handheld body 12 . A user (eg, a production line operator) holds the hand-held body 12 to operate the smart hand-held tool 1 and process objects through the processing mechanism 14 . In this embodiment, the smart handheld tool 1 is an electric screwdriver (or a wrench), and the processing mechanism 14 includes a replaceable screwdriver bit 142 (or a sleeve), which is exposed on the handheld body 12 . The user can use the smart handheld tool 1 to rotate the screwdriver bit 142 (or the sleeve) (eg by triggering the switch 14a on the handheld body 12 ) to lock the screw (or nut) to the object, eg to fix the cover to the case body.

The control circuit of the smart handheld tool 1 includes a control module 16 , a track detection module 18 and a warning module 20 , all of which are disposed on the handheld body 12 . The control circuit can be implemented by one or more circuit board modules and matched electronic components. The control module 16 is electrically connected with the track detection module 18 and the warning module 20 to control the operation of the track detection module 18 and the warning module 20 . The trajectory detection module 18 is used to detect the position or movement state of the processing mechanism 14 ; in practice, the trajectory detection module 18 may include a position sensor, a gyroscope, an accelerometer or an image capture device. The control module 16 can receive position data or movement data about the processing mechanism 14 from the trajectory detection module 18 . The warning module 20 can generate a warning message S1 according to the result of judging the trajectory data of the processing mechanism 14 by the trajectory detection module 18 . Wherein, in practice, the processing position of the processing mechanism 14 may be the relative position of a plurality of processing positions (for example, the three positions are distributed in a regular triangle), or may be relative to the position of the object to be processed (for example, using image capture means 182 to determine the position of the processing mechanism 14 relative to the object). In addition, in practice, it can be determined whether the position of the processing mechanism 14 belongs to the processing position by judging whether the processing mechanism 14 is processing (for example, when the processing mechanism 14 rotates the screwdriver bit 142 as processing), whether the position of the processing mechanism 14 belongs to the processing position, or is only in the process of moving Temporary suspension in .

Please also refer to FIG. 3 , which shows the movement trajectory of the smart handheld tool 1 according to an example. In this example, the user sequentially moves the smart handheld tool 1 to a plurality of processing positions P1 to P5 according to processing requirements (eg, recorded on the work order) to lock the object. During this operation, the control module 16 will evaluate the processing quality according to a processing instruction S2. For example, the machining instruction S2 includes a machining sequence. The control module 16 determines, through the trajectory detection module 18, the trajectory data of a plurality of processing positions P1-P5 of the processing mechanism 14 in time sequence during processing; wherein, as shown in FIG. 3, the movement sequence of the processing mechanism 14 is: It starts from the processing position P1, passes through the processing positions P2~P4 in sequence, and ends at the processing position P5 (that is, as shown by the thin solid line with the arrow in Fig. 3). If the machining sequence is also sequentially moved to the machining positions P1-P5, the movement track of the smart hand tool 1 (or the machining positions P1-P5) shown in FIG. 3 conforms to the machining sequence. If the control module 16 determines that the plurality of processing positions P1 to P5 do not conform to the processing sequence (for example, the processing sequence (shown in Fig. 3 by a dotted line with arrows) is moved to the processing positions P1, P4, P2, and P5 in sequence. , P3, which is inconsistent with the movement track shown in FIG. 3), the control module 16 controls the warning module 20 to generate a warning message S1. The warning message S1 can be sound, light, vibration, text, graphics, etc., all of which can remind the user. In practice, the warning module 20 may include a vibrating element (such as an eccentric motor, a piezoelectric sheet or other devices that can generate vibration), an optical indicator 202 (such as one or more point light sources, array light sources, liquid crystal screens, etc.) , a sounding element 204 (such as a speaker or other devices that can generate sound) or other devices that can prompt the user to present the warning message S1.

In addition, in practice, the processing order is not limited to the order of standardizing all the processing positions P1 to P5. For example, taking the processing positions P1 to P5 shown in FIG. 3 as an example, the processing sequence may only require that part of the processing positions P1 , P2 , and P5 in the movement track of the smart hand tool 1 should be arranged in sequence. For this processing sequence, the movement trajectory shown in Figure 3 meets the requirements; the movement trajectory shown in Figure 4 (smart hand tool 1 moves to processing positions P1, P2, P5, P4, and P3 in sequence, with arrows The solid line shown in the figure also meets the requirements; the movement trajectory shown in Figure 5 (the smart hand tool 1 moves to the processing positions P1, P2, P3, P5, P4 in sequence, is shown in the figure by a thin solid line with an arrow). ) also meet the requirements.

In this embodiment, as shown in FIG. 2 , the control circuit of the smart handheld tool 1 includes a communication module 22 , which is disposed on the handheld body 12 and is electrically connected to the control module 16 . The control module 16 can receive the processing instruction S2 via the communication module 22, for example, the control module 16 is connected to an external server via wireless communication (such as but not limited to wireless local area network, Bluetooth, near field communication, etc.) or Wired connection, and receive processing instruction S2 from the server. In this way, the smart hand-held tool 1 can use corresponding processing instructions to evaluate the processing quality for different processing requirements (eg, different processing operations for different objects).

In addition, in this embodiment, as shown in FIG. 2 , the control module 16 is electrically connected to the processing mechanism 14 , so that the control module 16 can control the operation of the processing mechanism 14 . When the machining instruction S2 includes a machining parameter, the control module 16 can control the action of the machining mechanism 14 according to the machining parameter. In this embodiment, the processing mechanism 14 includes a motor 144 (eg, a servo motor), a rotary head 146 coupled to the motor 144 , and a torque sensor 148 coupled to the rotary head 146 . The rotating head 146 is exposed on the handheld body 12 , and the screwdriver bit 142 is detachably mounted on the rotating head 146 . The control module 16 can control the rotation of the motor 144 (including the rotation speed, the number of turns, etc.). The control module 16 can sense the actual torque of the rotary head 146 through the torque sensor 148, and make the rotary head 146 provide the required torque through feedback control. In practice, the processing parameter may include a locking torque, a locking number of turns or a locking rotational speed.

In addition, in this embodiment, the control module 16 can also obtain a plurality of actual machining parameters S3 (such as locking torque, locking turns or locking speed, etc.) of the machining mechanism 14 when the machining mechanism 14 is in the plurality of machining positions P1-P5 etc.), the control module 16 transmits the plurality of actual processing parameters S3 to the external server via the communication module 22 to facilitate production management (eg, rework or scrap the processed object). In practice, the control module 16 can also compare the actual machining parameter S3 with the machining parameter (of the machining instruction) to evaluate the machining quality. For example, when the control module 16 determines that the actual locking torque is insufficient or excessive, the number of locking turns is insufficient or excessive, and the rotation speed of the rotating head 146 is too slow or too fast, the warning module 20 can be controlled to generate the warning message S1.

In addition, in this embodiment, as shown in FIG. 2 , the control circuit of the smart handheld tool 1 includes a gesture detection module 24 , which is disposed on the handheld body 12 and is electrically connected to the control module 16 . The attitude detection module 24 may include a horizontal or vertical sensor, or a gyroscope. The control module 16 obtains the posture of the processing mechanism 14 through the posture detection module 24 . Similarly, in practice, the processing parameters may include the attitude requirements of the processing mechanism 14 during processing (such as maintaining a vertical or inclined angle range, such as +/-10 degrees), and the control module 16 may detect the attitude during processing. The module 24 compares the attitude of the processing mechanism 14 with the attitude requirements of the processing parameters to evaluate the processing quality. Similarly, when the control module 16 determines that the actual posture does not meet the posture requirements of the processing parameters, it can control the warning module 20 to generate a warning message S1.

In addition, in practice, when the control module 16 judges that the processing quality is qualified, the control module 16 can also control the warning module 20 to generate a warning message S1 ′ to instruct the user that the operation is qualified. In practice, the aforementioned evaluation of the processing quality can be classified into levels, and the warning messages S1 and S1 ′ can also have multiple presentation levels correspondingly. For example, a green light indicates a qualified operation, for example, the smart hand-held tool 1 performs processing according to the processing sequence or processing parameters; yellow light indicates a defective operation, for example, the smart hand-held tool 1 does not perform processing accurately according to the processing sequence or processing parameters (for example, the processing mechanism 14 Unstable operation trajectory, working attitude, locking torque, etc.); red light indicates wrong operation, for example, smart hand tool 1 obviously deviates from the processing sequence or processing parameters to perform processing (such as sequence operation error, torque, number of turns, attitude , the speed is out of the setting range...etc).

In addition, the power source of the smart handheld tool 1 can be a battery or a common power source (connected by a power cord). The power source for the processing mechanism 14 may also be a battery, a common power source, or compressed gas. In addition, the above-mentioned smart hand tool 1 is described by taking an electric screwdriver (or wrench) as an example, but in practice, the smart hand tool of the present invention can also be applied to other processing processes. For example, if the rotating head 146 of the smart hand tool 1 includes a chuck to hold a rotary tool (such as a drill bit, a grinding wheel blade, a saw blade), the smart hand tool 1 can also be used for drilling, grinding, cutting, sawing and other machining operations . For another example, the smart handheld tool may be a welding gun, and the corresponding processing instructions (including the processing sequence and processing parameters) may include welding temperature, welding speed, welding posture, welding sequence, and the like. For another example, the smart hand-held tool may be an electric/pneumatic nail gun, and the corresponding processing instructions (including processing sequence and processing parameters) may include speed, pressure, fixed sequence, and the like.

As described above, the smart handheld tool 1 can evaluate the processing quality according to the processing instructions (including the processing sequence and processing parameters), and actively generate a warning message to remind the user, thereby preventing defective processed objects from remaining on the production line and increasing the consumption of subsequent processing. The cost and the management cost of manufacturing defective products (such as the cost of detection and recovery) can effectively solve the problem of abnormal product outflow in the prior art due to human negligence or failure to effectively implement processing standard operating procedures. In addition, the smart handheld tool 1 is convenient to move and can easily adapt to different work fields (for example, processing is performed indoors, outdoors, inside or outside the factory), and the smart handheld tool 1 can also actively control the processing according to the processing parameters of the processing instruction. The action of the mechanism 14 can achieve the effect of partial automation. The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
