Description

Technical Field

[0001] The utility model relates to a motor stator flat copper wire feeding starter and stopper, belonging to the technical field of copper wire feeding equipment. Background Art

[0002] The wire group on the stator of the brushless motor is composed of a plurality of flat copper wires arranged neatly in the shape of a "U"-shaped hairpin, and then the ends of the flat copper wires are welded to form a wire group; the cross-section of the flat copper wire is a rounded rectangle, which has good thermal and electrical conductivity. The hairpin-shaped flat copper wire is usually formed by feeding, straightening, pressing, removing paint film, bending and cutting the rolled flat copper wire. In the process of the rolled flat copper wire being transported from the material tray of the feeding mechanism to the straightening mechanism, a feeding starter and stopper will be set between the feeding mechanism and the straightening mechanism to match the feeding speed of the motor of the feeding mechanism with the straightening speed of the straightening mechanism, so as to avoid the problem that the feeding mechanism feeds the flat copper wire too slowly, which may cause the flat copper wire to be pulled, or the flat copper wire is fed too fast, which may cause the flat copper wire to be entangled with each other.

[0003] The existing feeding start and stop device includes a bottom plate, a bottom frame, a top frame, a copper wire guide and a mounting seat. The bottom plate is equipped with a bottom frame, the bottom frame is equipped with a top frame, and guide rods are symmetrically arranged between the bottom frame and the top frame. The copper wire guide is slidably installed on the guide rod. A round rod is arranged between the bottom frame and the top frame on one side of the copper wire guide, and a mounting seat is installed on the round rod at intervals through bolts. A detection in-position sensor for detecting the position of the copper wire guide is installed on the mounting seat through an assembly plate. The mounting seat is assembled by two semi-cylinders, each semi-cylinder is symmetrically provided with bolt holes, and semi-circular assembly holes are respectively arranged between the two semi-cylinders. The assembly holes are clamped with the round rod. When in use, the two semi-cylinders are clamped on the round rod by bolts, so that the position of the copper wire guide on the guide rod can be monitored, so that the motor speed of the feeding mechanism is adjusted by the program controller and the detection in-position sensor to control the feeding speed of the flat copper wire.

[0004] Although the mounting base in the above-mentioned feeding start and stop device can be fixed on the round rod by bolts, the detection position sensor is installed on the mounting base through the assembly plate, and the adjustment of the position of the mounting base on the round rod requires manual use of a screwdriver to loosen the screws for adjustment and then tighten the screws. The detection position sensor needs to be adjusted many times when it is first used. The manual loosening and tightening of the screws is troublesome, which will inevitably prolong the installation and debugging time, thereby reducing the overall feeding efficiency of the flat copper wire; at the same time, due to individual differences among employees, during the debugging and installation of the mounting base, since the mounting base is fixedly connected to the round rod through two semicircular assembly holes, the mounting base is prone to left and right deviations on the round rod, resulting in the mismatch between the detection position sensor on the mounting base and the copper wire guide, affecting the detection of the copper wire guide signal by the detection position sensor; on the other hand, when the copper wire guide slides up or down on the guide rod, it is easily affected by the swing amplitude of the flat copper wire, causing the copper wire guide to directly hit the top frame or the bottom frame, causing damage to the copper wire guide, directly affecting its service life; therefore, it is necessary to improve it.

[0020] As shown in the Figure 1-4 appendix

[0021] This motor stator flat copper wire feeding start-stop device includes a bottom plate 1, an underframe 2, a top frame 3, a copper wire guide 4 and an adjusting seat. The underframe 2 is fixedly installed on the bottom plate 1. The cross-section of the underframe 2 is in an "H" shape structure. The top frame 3 is fixedly installed on the upper surface of the underframe 2. The cross-section of the top frame 3 is in a "冂" shape structure. During operation, the cooperation of the underframe 2 and the top frame 3 effectively ensures the overall structural strength.

[0022] Adjusting blocks 5 are respectively fixedly installed on the underframe 2 and the top frame 3 by bolts. Guide rods 6 are symmetrically fixedly installed between the adjusting blocks 5 of the underframe 2 and the top frame 3. The guide rods 6 are round rods. A copper wire guide 4 is slidably installed on the guide rods 6. The copper wire guide 4 is in a long strip shape. Slide holes are symmetrically arranged on the copper wire guide 4 along the axial direction of the guide rods 6. The slide holes are in sliding connection with the guide rods 6 by cooperation. During use, the copper wire guide 4 can slide up or down along the guide rods 6.

[0023] An installation hole is opened in the center position of the copper wire guide 4 along the radial direction of the guide rod 6. A slide cylinder 7 is inserted into the installation hole. The edges of the two ends of the slide cylinder 7 with openings 15 are arc-shaped. During operation, the flat copper wire is pulled out by the feeding mechanism, passes through the slide cylinder 7, and is pulled to the straightening mechanism for straightening operation after passing through the slide cylinder 7. The copper wire guide 4 moves up or down on the guide rod 6 due to the swinging amplitude of the flat copper wire.

[0024] Limit rods 8 are arranged between the adjusting blocks 5 on one side of the guide rods 6. The limit rods 8 are long rods with a square cross-section. The two ends of the limit rods 8 are respectively fixedly connected to the adjusting blocks 5 of the underframe 2 and the top frame 3.

[0025] An upper adjustment seat 9, a middle adjustment seat 10 and a lower adjustment seat 11 are detachably installed on the limit rod 8 at intervals. The upper adjustment seat 9, the middle adjustment seat 10 and the lower adjustment seat 11 have the same structure. The adjustment seat includes a seat body 12 and a locking piece 13. A locking groove 14 is provided on the seat body 12. The locking groove 14 is in a long rectangular shape. An opening 15 is provided on the seat body 12 on one side of the locking groove 14. The locking groove 14 is connected to the opening 15. The opening 15 is inserted in cooperation with the limit rod 8. The locking groove 14 is inserted in cooperation with the limit rod 8. The purpose of such a setting is to facilitate the limit rod 8 to enter the locking groove 14 from the opening 15.

[0026] A locking member 13 is provided in the locking groove 14 on one side of the limit rod 8. The locking member 13 includes a locking rod 16, a locking head 17 and a reset spring 18. The locking rod 16 is movably inserted on the seat body 12. One end of the locking rod 16 extends to the outside of the seat body 12. The end of the locking rod 16 extending to the outside of the seat body 12 is fixedly installed with a pull handle 19. The other end of the locking rod 16 extends into the locking groove 14. The end of the locking rod 16 extending into the locking groove 14 is fixedly installed with a locking head 17. The locking head 17 is rectangular in shape. The locking head 17 is slidably connected with the locking groove 14. There is a locking rod 16 between the locking head 17 and the inner wall of the locking groove 14. A return spring 18 is provided, and the two ends of the return spring 18 are respectively in contact with the inner wall of the locking groove 14 and the lock head 17; when working, the handle 19 is pulled outward to move, so that the locking rod 16 and the lock head 17 slide from one end of the locking groove 14 to the other end. In this process, the return spring 18 is compressed and energy is stored, and the lock head 17 makes way for the opening 15, so that the limit rod 8 can enter the locking groove 14 from the opening 15. The limit rod 8 entering the locking groove 14 will be subjected to a pressure from the lock head 17 under the elastic force of the return spring 18, thereby realizing the installation of the adjustment seat on the limit rod 8.

[0027] Since the locking groove 14 is in the shape of a long rectangular strip and the limiting rod 8 is a long rod with a square cross-section, the limiting rod 8 can form a circumferential limit on the locking groove 14. The adjusting seat can slide upward or downward along the limiting rod 8 through the locking groove 14, and the adjusting seat cannot rotate on the limiting rod 8, thereby avoiding left and right deviation of the adjusting seat when adjusting the up and down position on the limiting rod 8.

[0028] Under the elastic force of the return spring 18, the lock head 17 of the locking member 13 forms a positive thrust on the limit rod 8, and the lock head 17 and the limit rod 8 maintain a contact connection. Under the elastic force of the return spring 18, the return spring 18 generates a reverse thrust on the seat body 12, so that the inner wall of the locking groove 14 of the seat body 12 maintains a contact connection with the limit rod 8. With the mutual cooperation of the lock head 17, the return spring 18 and the seat body 12, the adjustment seat is fixed on the limit rod 8.

[0029] The seat body 12 is provided with a flange 20 , which is provided with an assembly hole, and a position detection sensor 21 (model: XS7C1A1DAL2) is inserted into the assembly hole. The position detection sensor 21 is provided corresponding to the copper wire guide 4 , and the position detection sensor 21 is a commercially available part.

[0030] Buffer springs 22 are respectively provided on the corresponding adjustment blocks 5 at both ends of the guide rod 6. The buffer springs 22 are sleeved on the guide rod 6 to form a buffer for the adjustment block 5 when in use to prevent the adjustment block 5 from hitting the top frame 3 or the bottom frame 2.

[0031] The motor stator flat copper wire feeding start and stop device is provided with a controller (model PLCS7-800), which is electrically connected to the in-place detection sensors 21 on each adjustment seat and the feeding mechanism. The controller can sequentially and orderly control the in-place detection sensors 21 on each adjustment seat and the feeding mechanism to operate.

[0032] When the motor stator flat copper wire feeding starter and stopper is used, the rolled flat copper wire on the feeding mechanism material tray is first pulled in front of the feeding starter and stopper, and the flat copper wire is passed through the sliding sleeve of the copper wire guide 4, and then continued to be pulled to the straightening mechanism. After the above preparations are completed, the straightening mechanism is started, and the straightening mechanism pulls the flat copper wire forward. The feeding mechanism drives the material tray with the rolled flat copper wire to rotate through the transmission shaft of the motor to cooperate with the straightening mechanism to feed. In the process of straightening production, the flat copper wire between the straightening mechanism and the feeding mechanism will produce amplitude changes due to the influence of the next station of the straightening mechanism.

[0033] When the straightening speed of the flat copper wire by the straightening mechanism becomes faster, the flat copper wire between the straightening mechanism and the feeding mechanism will gradually straighten from a curved shape to an oblique straight shape, and the flat copper wire drives the copper wire guide 4 to move upward along the guide rod 6. At this time, when the in-position sensor 21 of the upper adjustment seat 9 detects the copper wire guide 4, the in-position signal is transmitted to the controller, and the controller controls the motor of the feeding mechanism to speed up the rotation speed of the material tray containing the rolled flat copper wire, thereby increasing the feeding speed and maintaining the balance of the feeding speed of the flat copper wire between the straightening mechanism and the feeding mechanism.

[0034] When the straightening speed of the flat copper wire by the straightening mechanism slows down, the curvature of the flat copper wire between the straightening mechanism and the feeding mechanism changes from small to large, and the flat copper wire drives the copper wire guide 4 to move downward along the guide rod 6. At this time, when the in-position sensor 21 of the middle adjustment seat 10 detects the copper wire guide 4, the in-position signal is transmitted to the controller, and the controller controls the motor of the feeding mechanism to slow down the rotation speed of the material tray containing the rolled flat copper wire, thereby reducing the feeding speed and maintaining the balance of the flat copper wire feeding speed between the straightening mechanism and the feeding mechanism.

[0035] When the straightening mechanism stops straightening the flat copper wire, the flat copper wire between the straightening mechanism and the feeding mechanism will gradually change from a small curve to a larger curve, and the flat copper wire drives the copper wire guide 4 to move downward along the guide rod 6 until the detection in-position sensor 21 of the lower adjustment seat 11 detects the copper wire guide 4, and transmits the in-position signal to the controller. The controller controls the motor of the feeding mechanism to stop rotating, and controls the brake mechanism to contact the material tray through the programmable controller, so that the material tray with the rolled flat copper wire stops rotating, and the feeding start-stop machine is realized. On the contrary, when the detection in-position sensor 21 of the lower adjustment seat 11 does not detect the copper wire guide 4, the controller controls the motor of the feeding mechanism to start, and the motor drives the material tray with the rolled flat copper wire to rotate, and the feeding start-stop machine is realized.

[0036] When the motor stator flat copper wire feeding starter and stopper is used, the locking groove 14 of the seat body 12 is clamped with the limit rod 8, and the limit rod 8 forms a limit on the seat body 12. Compared with the mounting seat 22 and the round rod 23 of the existing feeding starter and stopper, the motor stator flat copper wire feeding starter and stopper can prevent the seat body 12 from being offset left and right when it is adjusted along the limit rod 8. The locking groove 14 can be inserted into the limit rod 8 through the opening 15, and the limit rod 8 can be locked in place through the locking rod 16, the lock head 17 and the reset spring 18 of the locking member 13. It is locked in the locking groove 14 and can be quickly unlocked by pulling the handle 19, which makes it convenient for the staff to adjust the position of the detection in-position sensor 21 through the adjustment seat; the buffer spring 22 can effectively reduce the hard contact of the copper wire guide 4 on the base frame 2 and the top frame 3, reduce the risk of damage to the copper wire guide 4, and extend its service life; the motor stator flat copper wire feeding starter and stopper effectively reduces the installation and debugging time of the existing mounting seat, improves the flat copper wire feeding work efficiency, and prevents the mounting seat from shifting during the installation and debugging process.
