It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
An object of the present embodiment is to provide a casing transportation detection mechanism, which is used to detect whether the transportation length of a casing is in place and send a signal according to the detection condition, and perform subsequent adjustment processing in time, thereby improving the working efficiency, having high accuracy, and significantly reducing the production error rate. The purpose of this embodiment is also to provide a transformer coil threading and winding machine including the above bushing conveying and detecting mechanism.
Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the contents of the invention recited in the claims. The entire contents of the configurations shown in the following embodiments are not limited to those required as solutions of the inventions described in the claims.
Referring to fig. 1 to 4, the sleeve detecting mechanism provided in this embodiment is used for detecting the displacement size of the sleeve 10 driven by the conveying mechanism, and may be used for winding the sleeve 10 of the transformer coil, or in other scenes where the displacement size of a moving member needs to be detected, and is not limited to the production of the transformer coil. The sleeve conveying detection mechanism comprises a fixed seat 1 for providing fixed support, a rotating wheel assembly connected to the fixed seat 1 and used for rotating along with the movement of a sleeve 10, a sensor assembly used for outputting a detection signal, and a controller used for receiving the detection signal and sending a prompt signal.
Wherein, the rotating wheel component is rotationally connected on the fixed seat 1. The sleeve conveying detection mechanism is positioned on the conveying path of the sleeve 10, the outer side wall of the rotating wheel assembly is used for abutting against the outer side wall of the sleeve 10, so that a large friction force exists between the rotating wheel assembly and the sleeve 10, and when the sleeve 10 is dragged by the conveying mechanism to move, the rotating wheel assembly rotates along with the sleeve and stops when the sleeve 10 stops moving. The rotating wheel assembly rotates along the self rotating central axis.
The sensor assembly comprises a rotating part 4 which rotates synchronously with the rotating wheel assembly and a sensor 5 which is acted on by the rotating part 4 and enables the sensor assembly to send out a detection signal. The sensor 5 has a sensing field for moving the rotating member 4. Movement of the rotatable member 4 within the field of influence causes the sensor to generate a detection signal. The rotating member 4 is connected to the rotating wheel assembly and rotates synchronously therewith, the rotating member 4 is provided with a plurality of rotating members which are uniformly distributed along the circumferential direction of the rotating path, and the initial displacement point of each rotating member 4 can correspond to the initial displacement position of the sleeve 10 for each operation of the sleeve 10. The initial displacement position of the casing 10 has a rotor 4 associated with it each time the casing 10 is worked. The shear position of the casing 10 can be used as a starting position, which is fixed. When the rotating member 4 corresponding to the position moves, the rotating member is in or can generate a detection signal through the action of the induction field of the sensor 5 and the induction field, the sensor can send out the detection signal when the sleeve 10 starts to move, and stops outputting the signal when the sleeve 10 stops moving, and the detection signal sent by the sensor and the displacement size of the sleeve 10 have a quantitative relation due to the fact that the rotating member 4 moves in the induction field.
For example, each time the sleeve 10 is conveyed, a plurality of rotating parts 4 correspond to the rotating parts, the distance between every two adjacent rotating parts 4 is set to be small, the size of the induction field on the displacement path is set to be small, each rotating part 4 can penetrate through the induction field when moving, the inductor 5 can send out a plurality of opening and closing signals uniformly and continuously, the controller records the times of the opening and closing signals sent by the inductor when the sleeve 10 moves, and the times of the opening and closing signals sent by the inductor when the sleeve 10 moves are compared with the times which should be sent in the preset displacement size, so that whether the actual displacement size of the sleeve 10 reaches the preset displacement size or not can be.
The controller can know the actual displacement size of the sleeve 10 through the detection signal, compares the actual displacement size with the required preset displacement size, and sends out a prompt signal according to the comparison result. If the comparison result shows that the actual displacement size reaches the preset displacement size, the controller can display or send a normal signal or not send a signal; if the comparison result shows that the actual displacement size is smaller than the preset displacement size, the controller can display an alarm or an abnormal signal so as to be timely known by an operator and enable the equipment to timely stop subsequent operation when the actual displacement size of the casing 10 is smaller than the required preset size. Therefore, the production adjustment can be performed in time when the problem that the sleeve 10 is not in place in length is caused at every time, the error rate of production and the whole product is obviously reduced, and the accuracy and the working efficiency are improved.
The controller can also be electrically connected with a power device of the conveying mechanism of the sleeve 10, and when an alarm or an abnormal signal is sent out, the conveying mechanism can be stopped at the same time, so that the situation that the sliding between the sleeve 10 and the conveying mechanism is more serious along with the longer service time is avoided.
The controller can be a single chip microcomputer or a PLC with the model number of Siemens 7-200smart in the prior art, and can also be an integrated circuit or control software. The prompt signal can be sent by a display screen for information display, or by an electrically connected signal prompt device, such as a buzzer or a motor, for sending a buzzing or vibrating signal. The sensor assembly that sends out the signal is connected on PLC's input terminal, and signal prompt device connects on PLC's output terminal.
According to the above detection method: each time the sleeve 10 is fed, there are a plurality of rotating members 4 corresponding thereto. The rotating wheel component comprises a rotating shaft 3 connected with the fixed seat 1 and a rotating wheel 2 sleeved on the rotating shaft 3. The wheel 2 abuts against the outer side wall of the sleeve 10, and when the sleeve 10 moves, the friction between the sleeve 10 and the wheel 2 will cause the wheel 2 to rotate. The rotating member 4 may be connected to the rotating wheel 2 or the rotating shaft 3 and rotates synchronously with the rotating wheel 2, so that the closed circular path of the rotating wheel assembly is the circumferential direction of the rotating wheel 2 or the rotating shaft 3. The plurality of rotating members are arranged uniformly in the circumferential direction. The sensor 5 is configured as a sensor having a sensing space, the sensor being in communication with the controller, the sensing space forming a sensing field. The distance between the connecting ends of the sensing space and the rotating part 4 for fixed connection is less than the length of the rotating part 4, and the other end of the rotating part 4 can extend into the sensing space. As the wheel 2 rotates, the other end of each rotor 4 passes through the field in turn. The sensor 5 sends out a signal when each rotating part 4 passes by, the controller records the signal times sent out by the sensor 5 in each sleeve 10 conveying operation, and whether the actual displacement size of the sleeve 10 reaches the preset size can be known according to the proportional relation between the times and the displacement.
The rotating member 4 may be a blade and the sensor 5 may be an opto-electronic switch. The inductor 5 is connected to the fixed seat 1 through bonding or fastening pieces. If the photoelectric switch is a groove-type photoelectric switch. The light beam of the photoelectric switch is emitted from one end of the groove to the other end, and the groove forms an induction field. The direction of irradiation of the light beam is made to intersect the direction of rotation of the blade, preferably perpendicularly. When one blade enters the induction field, a light beam can be shielded, so that the photoelectric switch sends a signal, when the blade penetrates out of the induction field, the shielding is removed, the light beam is recovered, the next blade enters the sensor to shield the light beam again, and the photoelectric switch sends the signal again. The controller records the signal number of the photoelectric switches in the conveying operation of each sleeve 10, so that the passing number of the blades can be known, and the linear displacement of the sleeve 10 can be converted according to the angle of the total rotating stroke of the blades.
The rotating member 4 may also be a magnet block or a magnet piece, the sensor 5 is a hall sensor, and the magnetic lines of force of the hall sensor are emitted to form a magnetic field, which forms the induction field in the embodiment, so that the extending direction of the magnetic lines of force intersects with the rotating direction of the magnet block. When the magnet block passes through the induction field in sequence, the magnetic force of the magnetic field changes, the voltage output by the Hall sensor changes, the controller records the voltage change times of the sensor, the total rotation stroke of the magnet block can be known, and the linear displacement of the sleeve 10 can be converted.
In both cases, the distance between two adjacent rotating members 4 is small, which is detected according to the number of the rotating members 4 passing through the induction field in each stroke. When the rotating member 4 is a magnet block, the magnet blocks may be located on one circular piece at intervals in the circumferential direction of the circular piece. As the circular plate rotates, the magnet blocks and the spacing may cause a signal change in the induced field, causing the inductor 5 to output a continuously changing signal.
When the rotating member 4 is a vane, the connecting ends of the respective vanes are adjacent to each other with a gap at the other end to achieve better detection. In this embodiment, as shown in fig. 2, the connecting ends of the blades are connected in sequence and are in an integrated structure, so that each blade forms a circular sensing piece. And a gap is formed between the other ends of every two adjacent blades. As the sensing plate rotates, the vanes and notches may cause a signal change in the sensing field, causing the sensor 5 to output a continuously changing signal. The response piece can be connected on runner 2, and runner 2 passes through the bearing and rotationally is connected with pivot 3, pivot 3 and 1 fixed connection of fixing base. Or the induction sheet is connected at the end part of the rotating shaft 3, and the rotating shaft 3 is rotatably connected with the fixed seat 1 through a bearing, is fixedly connected with the inner hole of the rotating wheel 2 and synchronously rotates along with the rotating wheel 2.
Of course, the magnet blocks may be connected to a circular plate having a notch in the circumferential direction, the notch forming a space between two adjacent magnet blocks. The magnet blocks are connected to the circular sheet by bonding or embedding.
When the sleeve 10 is displaced in the reverse direction under certain requirements, the rotating wheel 2 is caused to rotate in the reverse direction, and the vanes or the magnet blocks reversely pass through the induction field, so that the sensor 5 is caused to output a change signal, and the controller outputs an improper prompt signal. To prevent this, in this embodiment, the cannula-feeding detecting mechanism is further provided with a structure for preventing the reverse rotation of the rotary wheel 2. As shown in fig. 2 and 4, the fixed seat 1 is connected with a blocking piece 6, the blocking piece 6 is located on the rotation path of the rotation piece 4, and if the vertical distance between the blocking piece 6 and the connection end of the rotation piece 4 is set to be smaller than the length of the rotation piece 4, one end of the blocking piece 6 is clamped between two adjacent rotation pieces 4. And two mutually perpendicular surfaces of the one end are set as a sheet surface 61 and an end surface 62, respectively. The face 61 is perpendicular to the plane of the rotor 4 and to each radial direction of the rotor 2, the face 61 extending in the direction of the thickness of the rotor 4 and having a dimension greater than the thickness of the rotor 4. The blocking sheet 6 can generate elastic deformation along the radial direction of the runner 2 and cannot generate elastic deformation in other directions. The end face 62 is perpendicular to the plane of the rotor 4 and parallel to one of the radial directions of the rotor 2.
