An electromagnetic coil in the transformer is wound on the iron core, and connectors at two ends of the coil are respectively connected with a power supply lead. In the prior art, devices such as a transformer coil bobbin winding and encapsulation integrated machine are provided which automatically wind a wire onto a core and sleeve an insulating sleeve over the wire or at the joints of the two ends of the wire. The transformer coil poling, winding and encapsulation all-in-one machine comprises a poling assembly, a shearing assembly, a winding assembly and a controller for controlling automatic operation of each assembly. The poling assembly includes a first conveying mechanism and a second conveying mechanism. In the process of manufacturing the transformer by using a winding and encapsulation integrated machine for the transformer coil, firstly, a wire is straightened and clamped on a first conveying mechanism, and the first conveying mechanism clamps the wire and can convey the wire along a straight line direction; the insulating sleeve to be sleeved on the wire is straightened and clamped on the second conveying mechanism, and the second conveying mechanism clamps the insulating sleeve and can convey the insulating sleeve in a straight line direction. Because the wire and the insulating sleeve have hardness, the wire and the insulating sleeve can be kept in a straight line state, the end part of the wire, which is required to be sleeved with the insulating sleeve, is conveyed to a sleeve conveying operation point and is in an extending state, the wire conveyed to the sleeve conveying operation point is aligned with the coaxial wire of the insulating sleeve, and then the second conveying mechanism continues to convey the insulating sleeve forwards, so that the insulating sleeve can be sleeved on the wire. When the insulating sleeve is displaced to the required sleeving length, the controller enables the shearing assembly to act according to the corresponding set time length, the insulating sleeve is sheared, the wire clamping device of the winding assembly clamps the end part of the wire sleeved with the insulating sleeve and pulls the end part of the wire to the pin of the transformer for winding and fixing, and then the winding assembly winds the rest part of the wire on the iron core.
In fig. 1, a conveying mechanism in the prior art is shown, an insulating sleeve 10 is clamped in two opposite rollers 20, and the rollers 20 are driven by a power device to rotate, so that the insulating sleeve 10 moves linearly to complete the production operation of sleeving a wire. In this process, the transport length of the insulating sleeve 10 is an important technical element. If the insulating sleeve 10 is not sleeved into the wire and generates resistance due to touching the wire or other components, or resistance is generated in the sleeving process of the insulating sleeve 10, the insulating sleeve 10 and the roller 20 can slip, the insulating sleeve 10 can not move forward any more, when the cutting assembly cuts the insulating sleeve 10 according to the set time, the insulating sleeve 10 on the wire can not reach the required sleeving length, a controller or a person can not know that the equipment still performs the step-down operation, and the production error is caused.
In view of this, there is a need to solve the problems that in the prior art, when the existing equipment is used to produce the bushing and winding of the transformer, the insulation bushing may not reach the required sleeving length, and the equipment or personnel cannot know in time that the adjustment results in higher production error rate.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
The aim of this embodiment is to provide a sleeve pipe conveying detection mechanism, whether it is used for detecting the sleeve pipe and carries length in place and send the signal according to the detection condition to in time carry out follow-up adjustment processing, improved work efficiency, and the precision is high, makes the production error rate show and reduces. The purpose of this particular embodiment is still to provide a transformer coil poling coiling machine including above-mentioned sleeve pipe transport detection mechanism.
Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the content of the invention described in the claims. The whole contents of the constitution shown in the following examples are not limited to the solution of the invention described in the claims.
Referring to fig. 1-4, the sleeve detection mechanism provided in this embodiment is used for detecting the displacement size of the sleeve 10 driven by the conveying mechanism, and can be used for winding production of the sleeve 10 of the transformer coil, and also can be used in other scenes where the displacement size of a moving member is required to be detected, and is not limited to production of the transformer coil. The casing 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 casing 10, an inductor assembly used for outputting detection signals, and a controller used for receiving the detection signals and sending prompt signals.
Wherein, the rotating wheel assembly is rotatably connected to the fixed seat 1. The sleeve conveying detection mechanism is positioned on a conveying path of the sleeve 10, the outer side wall of the rotating wheel assembly is used for being abutted against the outer side wall of the sleeve 10, and a large friction force exists between the rotating wheel assembly and the sleeve 10, and when the sleeve 10 is pulled and conveyed by the conveying mechanism to generate movement, the rotating wheel assembly rotates along with the sleeve 10 and stops when the sleeve 10 stops moving. The rotating wheel assembly rotates along the self-rotation central axis.
The sensor assembly includes a rotating member 4 rotating in synchronization with the rotating wheel assembly, and a sensor 5 acting on the rotating member 4 to cause the sensor assembly to emit a detection signal. The inductor 5 is provided with an induction field for the movement of the rotating member 4. Movement of the rotating member 4 within the induction field causes the sensor to generate a detection signal. The rotating members 4 are connected to the rotating wheel assembly and synchronously rotate therewith, the rotating members 4 are provided with a plurality of rotating members evenly 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 sleeve 10 operation. Each time the sleeve 10 is operated, the initial displacement position of the sleeve 10 has a corresponding rotating member 4. The shearing position of the sleeve 10 may be taken as a starting position, which is fixed. When the rotating member 4 corresponding to the position moves, the detecting signal is generated by the action of the induction field of the inductor 5 and the induction field, the inductor can send out the detecting signal when the sleeve 10 starts to move, and the signal output is stopped when the sleeve 10 stops moving, and the rotating member 4 moves in the induction field, so that the detecting signal sent out by the inductor has a quantitative relation with the displacement size of the sleeve 10.
For example, each time the casing 10 is conveyed, there are a plurality of rotating members 4 corresponding to the rotating members, the distance between every two adjacent rotating members 4 is set to be smaller, the size of the induction field on the displacement path is set to be smaller, each rotating member 4 passes through the induction field when moving, the inductor 5 sends out a plurality of switching signals uniformly and continuously, the controller records the times of the switching signals sent out by the inductor when the casing 10 moves, and compares the times with the times which should be sent out in the preset displacement size, so as to know whether the actual displacement size of the casing 10 reaches the preset displacement size.
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 out a normal signal or not send out 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 abnormal signal so as to timely provide the operator with knowledge and timely stop the subsequent operation of the device when the actual displacement size of the sleeve 10 is smaller than the required preset size. Therefore, production adjustment can be timely carried out when the problem that the sleeve 10 is not sleeved in place in length each time occurs, the error rate of production and overall products 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 can simultaneously stop the conveying mechanism when an alarm or abnormal signal is sent out, so that the situation that the sleeve 10 and the conveying mechanism slip more seriously along with the longer service time is avoided.
The controller can be a singlechip or a PLC with the model of Siemens 7-200smart in the prior art, and also can be an integrated circuit or control software. The prompt signal can be displayed through a display screen, or can be sent through an electric connection signal prompt device, such as a buzzer or a motor. The sensor component sending out the signal is connected on the input terminal of PLC, and signal prompt device is connected on the output terminal of PLC.
According to the detection mode: each time the casing 10 is transported, there are a plurality of rotating members 4 corresponding thereto. The rotating wheel assembly 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 is in abutment with the outer side wall of the sleeve 10 and when the sleeve 10 is moved, 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, and the closed annular 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 uniformly arranged in the circumferential direction. The sensor 5 is arranged as a sensor with a sensing space, which is in communication with the controller, the sensing space forming an induction field. The distance between the upper part of the sensing space and the rotating end of the rotating member 4 for fixed connection is smaller than the length of the rotating member 4, and the other end of the rotating member 4 can extend into the sensing space. The other end of each rotating member 4 passes through the induction field in turn as the wheel 2 rotates. The sensor 5 sends out signals when each rotating member 4 passes by, the controller records the number of times of the signals sent by the sensor 5 in each sleeve 10 conveying operation, and according to the proportional relation between the number of times and displacement, whether the actual displacement size of the sleeve 10 reaches the preset size can be known.
The rotor 4 may be a blade and the inductor 5 may be a photoelectric switch. The inductor 5 is connected to the fixing base 1 by bonding or fastening. If the photoelectric switch is a groove type photoelectric switch, the groove type photoelectric switch can be used. 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 irradiation direction of the light beam is made to intersect the rotation direction of the blade, preferably perpendicularly. When one blade enters the induction field, the light beam is blocked, so that the photoelectric switch sends out a signal, when the blade passes out of the induction field, the blocking is removed, the light beam is recovered, the next blade enters to block the light beam again, and the photoelectric switch sends out a signal again. The controller records the number of signals of the photoelectric switch in each sleeve 10 conveying operation, 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 rotation stroke of the blades.
The rotating member 4 may also be a magnet block or a magnet sheet, and the sensor 5 is a hall sensor, and magnetic lines of force of the hall sensor are emitted to form a magnetic field, so that the magnetic field forms an induction field in this embodiment, and an extending direction of the magnetic lines of force intersects with a rotating direction of the magnet block. When the magnet blocks sequentially pass through the induction field to cause magnetic force change of the magnetic field, voltage output by the Hall sensor changes, the controller records the voltage change times of the sensor, and the total rotation stroke of the magnet blocks can be known, and the linear displacement of the sleeve 10 can be converted.
Both of these structural conditions are detected based on the number of induced fields that the rotating member 4 passes through in each stroke, and the distance between every two adjacent rotating members 4 is small. When the rotary member 4 is a magnet block, the magnet blocks may be located on one circular piece, and may be spaced apart in the circumferential direction of the circular piece. When the circular plate rotates, the magnet blocks and the spacing can cause the signal of the induction field to change, causing the inductor 5 to output a continuously changing signal.
When the rotor 4 is a blade, the connection ends of the respective blades are adjacent to each other with a gap at the other end, so that detection is better achieved. In this embodiment, as shown in fig. 2, the connection ends of the blades are sequentially connected and are in an integral structure, so that each blade forms a circular sensing piece. A gap exists between the other ends of every two adjacent blades. When the sensor blade rotates, the blade and notch may cause the signal of the sensor field to change, causing the sensor 5 to output a continuously changing signal. The induction piece can be connected to the rotating wheel 2, the rotating wheel 2 is rotatably connected with the rotating shaft 3 through a bearing, and the rotating shaft 3 is fixedly connected with the fixing seat 1. Or the induction piece is connected to 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 with a notch along the circumferential direction, and the notch forms 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 reversely displaced under certain requirements, the rotating wheel 2 is reversely rotated, and the blades or the magnet blocks reversely pass through the induction field, so that the inductor 5 outputs a change signal, and the controller outputs an unsuitable prompting signal. To prevent this, in the present embodiment, the casing conveyance detecting mechanism is further provided with a structure for preventing the turning wheel 2 from turning upside down. As shown in fig. 2 and 4, the fixing base 1 is connected with a blocking piece 6, the blocking piece 6 is located on the rotating path of the rotating piece 4, the vertical distance between the blocking piece 6 and the connecting end of the rotating piece 4 is set to be smaller than the length of the rotating piece 4, and then one end of the blocking piece 6 is clamped between two adjacent rotating pieces 4. And two mutually perpendicular faces of the one end are set as a single face 61 and an end face 62, respectively. The plane 61 is perpendicular to the plane of the rotor 4 and perpendicular to the respective radial directions of the rotor 2, and the plane 61 extends in the thickness direction of the rotor 4 by a dimension greater than the thickness of the rotor 4. The blocking piece 6 can be elastically deformed in the radial direction of the rotating wheel 2, and cannot be elastically deformed in other directions. The end face 62 is perpendicular to the plane of the rotor 4 and parallel to a radial direction of the rotor 2. In the rotating process of the rotating member 4, the end part of the rotating member 4, which is used for passing through the induction field, can be propped against the surface 61 of the blocking piece 6 at a certain position, and along with the continuous rotation of the rotating member 4, the end part of the rotating member 4 can push the blocking piece 6 to enable the blocking piece 6 to generate elastic deformation, and one end of the rotating member is far away from the displacement of the rotating member 4. When the rotary member 4 rotates out of contact with the one surface 61 of the blocking piece 6, the blocking piece 6 returns to its elastic deformation, and the one end returns to the original position and is caught between the two rotary members 4. If the rotating wheel 2 rotates reversely, the rotating member 4 will abut against the end face 62 of the blocking piece 6, and the rotation is blocked by the blocking piece 6.
The blocking piece 6 may be a leaf spring which is characterized by a simple bending in one direction only, the plane of minimum stiffness, and a large tensile and bending stiffness in the other direction. One end of the spring piece is bonded with the fixing seat 1 or connected with a fastener, and the other end is clamped between the two rotating pieces 4.
