Detailed Description
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
In the description of the present invention, unless otherwise specified and limited, it is to be noted that the term "connected" is to be interpreted broadly, and may be, for example, a mechanical connection or an electrical connection, or a communication between two elements, or may be a direct connection or an indirect connection through an intermediate medium, and a specific meaning of the term may be understood by those skilled in the art according to specific situations.
The traditional measuring point is manually, and the research and development personnel can easily think of measuring the distance between the scissors and the fixed end of the object to be cut by using the distance sensor, but in the actual measurement, the fixed end of the object to be cut is usually clamped on the clamp at random, as shown in the combination of fig. 1, when the object to be cut is clamped obliquely, the direction of the clamp is different from the direction of the fixed end of the object to be cut, and in order to clamp the object to be cut, the object to be cut usually needs to extend into the clamp, if the scissors directly use the clamp, the distance L between the scissors and the clamp is detected by using the distance sensor, and the distance L is taken as the distance between the scissors and the fixed end of the object to be cut, so that the measurement accuracy is obviously. Therefore, the invention designs the auxiliary distance measuring device for cutting, which reflects the correct direction of the fixed end of the object to be cut, thereby accurately measuring the distance between the scissors and the fixed end of the object to be cut.
Referring to fig. 2, a front view of an embodiment of the auxiliary distance measuring device for cutting according to the present invention is shown. As shown in fig. 3, the auxiliary distance measuring device for clipping may include two layers of defining closed brackets 210 with the same structure and an auxiliary board 220 positioned in the defining closed brackets 210, each layer of defining closed brackets 210 includes two parallel cross bars 211 and two vertical bars 212 connecting corresponding ends of the two cross bars 211, the upper and lower layers of defining closed brackets 210 are connected by a connecting bar 213, the first cross bar positioned on the same side in the defining closed brackets 210 for each layer, on the side facing said auxiliary plate 220, an array of protrusions 214 is distributed, defining for each layer a second cross bar of the closed support 210 located on the same side, one side of the auxiliary plate 220 facing the auxiliary plate is movably connected with one end of the auxiliary plate 220, the other opposite end of the auxiliary plate 220 faces the first cross bar and is clamped between the protrusions of the protrusion array 214, the auxiliary plate 220 extends out from the closed shelf defined in the next layer to the closed shelf defined in the upper layer. After the scissors are attached to the auxiliary plate 220, the auxiliary plate 220 is driven to move so that the auxiliary plate 220 is aligned with the fixed end of the object to be cut, and after the scissors are separated from the auxiliary plate 220, the auxiliary plate 220 is kept aligned with the fixed end of the object to be cut under the action of the protrusion array 214.
In order to ensure that the scissors can move the auxiliary plate 220 and the auxiliary plate 220 is kept in the same direction by the protrusion array after the scissors leave the auxiliary plate 220, the second cross bar can be hinged to one end of the auxiliary plate 220, and the first cross bar is an arc with a radius equal to the length of the auxiliary plate 220, as shown in fig. 3. When the user uses the auxiliary distance measuring device, the user can first fix the object to be cut on the clip, and then use the scissors to touch the auxiliary board 220 in the auxiliary distance measuring device for cutting, so that the direction of the auxiliary board 220 changes with the change of the direction pointed by the scissors, when the user determines that the direction pointed by the scissors overlaps with the direction of the fixed end of the object to be cut, the user releases the auxiliary board 220, and the other opposite end of the auxiliary board 220 moves among the protrusions of the protrusion array 214 during the movement of the auxiliary board 220 driven by the scissors. Since one end of the auxiliary plate 220 is hinged to the second cross bar and the protrusion array 214 acts as a limit for the other opposite end of the auxiliary plate 220, even if the user releases the auxiliary plate 220, the direction of the auxiliary plate 220 is not changed and remains the same as the fixed end of the object to be cut.
It can be seen from the above embodiments that, by providing the auxiliary plate, one end of the auxiliary plate is movably connected to the second cross bar, and the other opposite end is fixed under the action of the protruding array on the first cross bar, the scissors can drive the auxiliary plate to move until the auxiliary plate is aligned with the direction of the fixed end of the object to be cut, and after the scissors leave the auxiliary plate, the auxiliary plate is kept aligned with the direction of the fixed end of the object to be cut, so that when measuring distance, if the scissors and the fixed end of the object to be cut face the same direction, the distance between the scissors and the auxiliary plate, which is detected by the first infrared distance sensor arranged on the scissors, is equal to the distance between the cutting end and the fixed end of the object to be cut, and the whole measurement is realized based on the sensor, rather than manually measuring a standard point, so that the accuracy and efficiency of; and the present invention is applicable even if the cut size exceeds the arm length range. In addition, the distance measuring auxiliary device for clipping is provided with two layers of limiting closed brackets, so that the auxiliary plate is convenient to fix, and the first infrared distance sensor on the scissors can measure the distance between the first infrared distance sensor and the auxiliary plate through the gap between the two layers of limiting closed brackets.
Although the auxiliary distance measuring device for clipping in the first embodiment of the auxiliary distance measuring device can ensure that the auxiliary plate 220 is moved by the scissors and the direction of the auxiliary plate 220 is kept unchanged by the protrusion array after the scissors leave the auxiliary plate 220, since the auxiliary plate 220 is hinged to the first cross bar 211 (the auxiliary plate 220 can only do circular arc motion with the hinged end as a circular point), if the extension line of the fixed end of the object to be clipped intersects with the hinged end of the auxiliary plate 220 as shown in fig. 4(a), the auxiliary plate 220 can be aligned with the direction of the fixed end of the object to be clipped without moving the auxiliary distance measuring device, but if the extension line of the fixed end of the object to be clipped does not intersect with the hinged end of the auxiliary plate 220 as shown in fig. 4(b), the entire auxiliary distance measuring device needs to be moved. To this end, the present invention further designs an auxiliary distance measuring device for cutting, as shown in fig. 5, an auxiliary board 220 is connected to the second cross bar 211 through a spring 215, so that both ends of the auxiliary board 220 can move, and a first distance sensor 216 and a first electric telescopic rod 218 are disposed on the first vertical rod on the same side in each layer of the limiting closed support 210, and a second distance sensor 217 and a second electric telescopic rod 219 are disposed on the second vertical rod on the same side.
The first distance sensor 216 is used for measuring the horizontal distance between the first electric telescopic rod 218 and the auxiliary board 220 on the corresponding layer defined closing bracket, the second distance sensor 217 is used for measuring the horizontal distance between the second electric telescopic rod 219 and the auxiliary board 220 on the corresponding layer defined closing bracket, and the first distance sensor 216 and the second distance sensor 217 are respectively connected with the controller and are used for transmitting the corresponding horizontal distance information to the controller. In the present invention, by designing the position relationship between the first distance sensor and the first electric telescopic rod and the position relationship between the second distance sensor and the second electric telescopic rod, the distance information detected by the first distance sensor can be used to represent the horizontal distance between the first electric telescopic rod and the auxiliary plate, and the distance information detected by the second distance sensor can be used to represent the horizontal distance between the second electric telescopic rod and the auxiliary plate.
After confirming that the scissors are aligned with the fixed end of the object to be cut, the controller controls the first electric telescopic rod 218 and the second electric telescopic rod 219 according to the corresponding horizontal distance information detected by the first distance sensor 216 and the second distance sensor 217 to fix one end of the auxiliary plate, wherein the other opposite end of the auxiliary plate is fixed under the action of the protrusions in the protrusion array, and when the two ends of the auxiliary plate are fixed, even if the scissors are separated from the auxiliary plate, the auxiliary plate is aligned with the fixed end of the object to be cut. The controller firstly judges whether the latest horizontal distance detected by the first distance sensor and the second distance sensor is greater than the corresponding preset distance before the scissors are aligned with the direction of the fixed end of the object to be cut, when the latest horizontal distance detected by the first distance sensor 216 is greater than the corresponding preset distance, the auxiliary plate 220 is deviated to the right, and the auxiliary plate 220 tends to move to the left, so that the controller controls the first electric telescopic rod 218 to extend the corresponding horizontal distance to fix one end of the auxiliary plate 220; when the latest horizontal distance detected by the second distance sensor 217 is greater than the corresponding preset distance, it indicates that the auxiliary board 220 is shifted to the left, and the auxiliary board 220 tends to move to the right, so that the controller controls the second electric telescopic rod 219 to extend the corresponding horizontal distance to fix one end of the auxiliary board 220. The preset distance may be a distance between the auxiliary board 220 and the corresponding vertical bar 212 when the auxiliary board 220 is not actuated.
It can be seen from the above embodiments that, the present invention can move both ends of the auxiliary plate by connecting one end of the auxiliary plate to the first cross bar through the spring, and can fix one end of the auxiliary plate by arranging the first distance sensor, the second distance sensor, the first electric telescopic rod and the second electric telescopic rod, and since the other opposite end of the auxiliary plate is fixed under the action of the protrusion array, the present invention can fix both ends of the auxiliary plate, so that the scissors can drive the auxiliary plate to move until the auxiliary plate is aligned with the fixed end of the object to be cut, and the auxiliary plate is aligned with the fixed end of the object to be cut after the scissors leave the auxiliary plate, therefore, when measuring distance, if the direction of the scissors is the same as that of the fixed end of the object to be cut, the distance between the scissors and the auxiliary plate detected by the first infrared distance sensor arranged on the scissors is equal to the distance between the cut end and the fixed end of the object to be cut, the whole measurement is realized based on a sensor instead of manually measuring the punctuation, so the accuracy and the efficiency of the measurement are higher, and the invention is also applicable even if the cutting size exceeds the range of the arm length; in addition, the auxiliary distance measuring device is also suitable for the condition that the extension line of the fixed end of the object to be cut is not intersected with the hinged end of the auxiliary plate on the premise of no movement, so that the auxiliary distance measuring device can realize the auxiliary distance measuring of various scenes on the premise of no movement, and has the advantages of wide application range and high flexibility.
When the auxiliary distance measuring device is used for measuring distance, the direction of the scissors and the direction of the fixed end of the object to be cut are required to be the same during distance measurement, and therefore the scissors are designed. As shown in fig. 6 and 7, the scissors may include a scissors head 110 and a handle 120 connected together, the scissors head 110 is connected together by a rotating shaft 130, and the handle 120 is provided with a first angle sensor 121 and an angle display 122; the first angle sensor 121 and the angle display 122 are respectively connected with the controller; the first angle sensor 121 is used for detecting the orientation angle of the scissor head 110 when the scissors are vertically arranged and sending the orientation angle to the controller; the controller confirms that the scissors is aimed at with the orientation that waits to cut the thing stiff end towards the back, will be before confirming the scissors and waiting to cut the thing stiff end towards the orientation alignment, the newest orientation angle that first angle sensor 121 detected sets up to the positive direction, and it is after receiving the orientation angle that first angle sensor 121 detected afterwards, calculates the contained angle between orientation angle and the positive direction to show this contained angle on angle display 122, from this angle display 122 will show the scissors and the contained angle of waiting to cut the thing stiff end towards the orientation, treat the contained angle between thing cutting end and the stiff end promptly. In the distance measuring process, a user can judge whether the scissors and the fixed end of the object to be cut face the same direction or not according to the angle displayed on the angle display.
When the user aligns the scissors and the fixed end of the object to be cut, the alignment between the scissors and the fixed end of the object to be cut can be realized by directly using the scissors body, but the alignment accuracy is low. For this purpose, the rotating shaft 130 of the present invention is provided with the infrared emitter 112, and the controller is configured to control the infrared emitter 112 to emit the infrared ray having the same orientation as the scissor head 110. The handle is further provided with a starting button connected with the controller, the starting button is pressed, the controller receives a starting signal, and the infrared emitter is controlled to emit infrared rays in the same direction as the direction of the scissors. According to the invention, the starting button is arranged, and the infrared emitter is controlled to emit infrared rays only when the starting button is pressed, so that the energy consumption can be reduced.
After the alignment of the scissors and the fixed end of the object to be cut is completed, the user needs to perform a corresponding operation to inform the controller that the alignment is completed. The scissors are normally in a closed state when the scissors are not used, and the scissors head is required to be in an open state when cutting is performed, so that the opening and closing states of the scissors head are utilized to confirm whether the scissors are aligned with the fixed end of the object to be cut. For this purpose, the scissor head 110 of the present invention is provided with a second angle sensor 111, the second angle sensor 111 is configured to detect an opening and closing angle of the scissor head 110 and send information of the opening and closing angle to the controller, and the controller determines whether the scissor head 110 is switched from the closed state to the open state according to a change of the opening and closing angle detected by the second angle sensor 111, wherein if the opening and closing angle is gradually increased, the controller may determine that the scissor head 110 is switched from the closed state to the open state, and if the opening and closing angle is gradually decreased, the controller may determine that the scissor head 110 is switched from the open state to the closed state. When the controller confirms that the scissor heads are converted from the closed state to the open state, the alignment of the scissors and the direction towards which the fixed end of the object to be cut faces is confirmed.
According to the invention, the scissor head is switched from the closed state to the open state to serve as a trigger condition for determining whether the scissors are aligned with the direction of the fixed end of the object to be cut, and a user only needs to operate the scissors according to normal habits in determining the direction of the fixed end and the cutting process without performing additional operation, so that good user experience can be provided, and the intelligent degree is higher. Because the scissors head is manually operated in the process of converting from the closed state to the open state, if the orientation angle detected by the first angle sensor is taken as the positive direction after the scissors head is converted from the closed state to the open state, the problem of low accuracy can exist, and similarly, if the horizontal distance detected by the first distance sensor and the second distance sensor in the auxiliary distance measuring device is controlled by the first electric telescopic rod and the second electric telescopic rod after the scissors head is converted from the closed state to the open state, the error of the orientation of the auxiliary plate and the fixed end of the object to be cut can be large, therefore, the latest orientation angle detected by the first angle sensor is set as the positive direction before the scissors head is converted from the closed state to the open state, and the accuracy of determining the orientation of the scissors in the distance measuring and cutting processes can be improved, and before the scissor head is converted from the closed state to the open state, the latest horizontal distance detected by the first distance sensor and the second distance sensor is used as a basis for controlling the first electric telescopic rod and the second electric telescopic rod, so that the alignment accuracy of the auxiliary plate and the fixed end of the object to be cut can be ensured.
In order to realize the sensor distance measurement, the auxiliary distance measuring device for cutting is arranged at the fixed end side of the object to be cut, a first infrared distance sensor is arranged on one side of the scissors facing the fixed end of the object to be cut, a distance display is arranged on one side of the handle facing a user when the scissors are vertically arranged, the first infrared distance sensor and the distance display are respectively connected with a controller, the first infrared distance sensor is used for measuring a first distance between the scissors and the auxiliary plate and transmitting the first distance information to the controller, the controller controls the distance display to display the first distance, and when the scissors and the fixed end of the object to be cut face in the same direction, the distance display displays the distance between the cutting end and the fixed end of the object to be cut.
When the device is used, a user can firstly fix the object to be cut at will, and presses the start button, at this time, the controller controls the infrared emitter 112 to emit infrared rays, the user attaches the scissors to the auxiliary plate 220 in the auxiliary distance measuring device to drive the auxiliary plate 220 to move, and in the process of driving the auxiliary plate 220 to move, the scissors are aligned with the fixed end of the object to be cut according to the alignment condition of the infrared rays and the fixed end of the object to be cut. When the scissors are aligned with the fixed end of the object to be cut, the user opens the scissors to enable the scissors to be converted into an open state from a closed state, at the moment, before the controller converts the scissor head into the open state from the closed state, the latest orientation angle detected by the first angle sensor is set to be the positive direction, and the auxiliary distance measuring device controls the first electric telescopic rod and the second electric telescopic rod according to the corresponding horizontal distance detected by the first distance sensor and the second distance sensor before the scissor head is converted into the open state from the closed state. Afterwards, the user ranges for distance, move the scissors to the side of tailorring, whether the angle on the at first observation angle display is zero at the ranging process, if, then for waiting to tailor thing stiff end translation, and observe the distance value that shows on the distance display, satisfy the requirement when the distance value, and the angle on the angle display is zero, it accomplishes to show the range finding, the user only need at this moment according to this moment the scissors towards the direction tailor can, the user keeps the angle on the angle display to be zero when tailorring, alright from this alright tailor out the rectangle cloth.
It can be seen from the above embodiments that the conventional cutting method requires at least twice measuring the punctuation and delineating the lines before cutting, and the user needs to perform two steps of fixing and infrared alignment before cutting, so the invention can improve the cutting efficiency. In addition, the traditional cutting mode is to cut based on manually drawn lines during cutting, the accuracy of cutting is low due to the introduction of manual factors, and the cutting accuracy can be ensured by cutting based on the angle information and the distance information detected by the sensor. In addition, the controller controls to turn off the infrared emission 112 after determining that the scissor head is switched from the closed state to the open state, whereby power consumption can be reduced. To facilitate the user's view of the angle on the angle display during cutting, the angle display is provided on the side of the handle 120 facing the user when the scissors are upright.
