Description

Technical Field

[0001] This invention relates to the field of welding assembly equipment technology, specifically to an automatic welding assembly equipment for shaded pole motor coils. Background Technology

[0002] The pole short-circuit ring coil of a shaded-pole motor is the core component that enables the motor to start automatically. It generates a rotating magnetic field through induced hysteresis flux, and features a simple structure, no additional starting components, low operating noise, and high reliability. These shaded-pole motors with short-circuit ring coils are widely used in small household appliances such as electric fans, heaters, and microwave ovens, where starting torque requirements are not high.

[0003] When assembling the short-circuit ring coil with the iron core of a shaded-pole motor, the U-shaped short-circuit ring coil is typically inserted into the corresponding short-circuit ring mounting hole on the iron core. After bending the end of the short-circuit ring, it is then welded to connect the beginning and end of the short-circuit ring. Since the iron core of a shaded-pole motor has a circular inner cavity for the rotor to rotate, and the short-circuit rings need to be distributed on opposite sides of the inner cavity when installed on the iron core, the short-circuit rings on the iron core of the shaded-pole motor have different widths. Consequently, conventional automatic welding and assembly equipment cannot quickly assemble the short-circuit ring coils of the shaded-pole motor. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic welding and assembly equipment for shaded-pole motor coils to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic welding and assembly equipment for shaded pole motor coils, including a workbench, a column is installed in the middle of the workbench, a support that can rotate intermittently is provided at the top of the column, and the support transports the iron core through a clamp installed at equal angles. The support and the clamp cooperate to realize the horizontal rotation and transfer of the iron core through height lifting and intermittent angle rotation.

[0006] The outer periphery of the column is provided with a feeding station, a support, a shaping station, a welding station and a unloading station. The workbench is provided with an insertion station corresponding to the support, for inserting short-circuit ring coils into the iron core placed above the support.

[0007] The forming station includes a bending mechanism for shaping the end of the short-circuit ring and a clamp for supporting the iron core. The bending mechanism for shaping the end of the short-circuit ring includes a bearing seat for abutting against and fitting the iron core from top to bottom. Through the bending mechanism of the forming station, U-shaped short-circuit rings of different widths can be quickly bent and fastened to the iron core.

[0008] The welding station consists of an inclined laser welding gun and a fixed base docked on the worktable. The welding station is used to weld and connect the connection gap of the short-circuit ring.

[0009] Preferably, a main shaft is inserted into the column and docked with the middle of the support. The cross-section of the lower end of the main shaft is a toothed structure. A rotary table is installed at the bottom of the worktable, and the output end of the rotary table is slidably connected to the lower end of the main shaft. The rotary table drives the clamp on the support to index and rotate a pair of iron cores through the main shaft.

[0010] Preferably, a cylinder is installed at the lower end of the rotary table, and the cylinder abuts against the bottom wall of the main shaft through a steel ball embedded in the top of its output end.

[0011] Preferably, the loading station includes a rotating block rotatably connected to the upper side of the workbench, and the rotating block is pushed, pulled and rotated by a telescopic rod that is laterally hinged to the upper side of the workbench;

A guide rod parallel to the output shaft of cylinder two is fixed on the upper surface of the rotating block, and the guide rod is slidably connected to the receiving rod.

[0013] Preferably, both the support and the top of the receiving rod are equipped with positioning seats for positioning the iron core.

[0014] Preferably, the insertion station comprises a Y-axis module, an X-axis module that moves along the Y-axis module, a Z-axis module that moves laterally along the X-axis module, and a second clamp that is raised and lowered via the Z-axis module. The clamping part at the bottom of the second clamp is a planar plate structure.

[0015] Preferably, a base is installed on the upper side of the workbench, and a cylinder four for driving the bending mechanism to rise and fall is connected to the base.

[0016] The tail of the clamping device three is connected to the output end of the motor one. The motor one is mounted on the workbench via a mounting base. The front end of the clamping part of the clamping device three is connected to a gasket for abutting the short-circuit ring to prevent the short-circuit ring from falling off the iron core.

[0017] Preferably, the bearing seat is connected to the output end of the cylinder four. The bottom wall of the bearing seat is integrally formed with a conical positioning pin for positioning the circular holes on opposite sides of the iron core surface. A motor is installed in the middle of the bearing seat, and the output end of the motor is connected to a pressure plate through a lead screw.

[0018] Preferably, two T-shaped rods are respectively provided at both ends of the pressure plate. One of the T-shaped rods is connected to the top wall of the other T-shaped rod by a spring. A slide rail is installed in the bearing seat. Two sets of guide blocks with wide and narrow spacing are connected in the slide rail to bend U-shaped short-circuit rings of different widths.

[0019] Preferably, the top of the fixed base is provided with a rotating seat with two protruding pins on the top wall, and a motor is installed inside the fixed base to drive the rotating seat to rotate circumferentially.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The automatic welding and assembly equipment for shaded pole motor coils, by combining the bracket and the clamp, can realize the rotation and transfer of the iron core at the feeding station, support, shaping station, welding station and unloading station through height lifting and intermittent angle rotation. After the iron core is fed at the feeding station, the short-circuit ring is clamped and inserted into the iron core above the support at the insertion station for preliminary docking. Then, the iron core is horizontally flipped and the ends of short-circuit rings of different widths are bent in succession at the shaping station, so that the iron core of the shaded pole motor and the short-circuit ring coil can be quickly fastened together. At the same time, the welding station is used to perform gap welding on the horizontally rotatable iron core, ensuring that the equipment can efficiently and quickly weld and assemble short-circuit rings of different widths onto the iron core of the shaded pole motor through continuous combination processing.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1 and Figures 3-5 This invention provides a technical solution: an automatic welding and assembly equipment for shaded-pole motor coils, including a workbench 1, a column 101 installed in the middle of the workbench 1, a support 102 that can rotate intermittently on the top of the column 101, and the support 102 transporting the iron core through a clamp 103 installed at equal angles. The clamping part of the clamp 103 is "L"-shaped, and the inner wall of the clamping part of the clamp 103 has anti-slip texture. The anti-slip texture on the wall can prevent slippage when the iron core is clamped horizontally. A main shaft 104 is inserted into the column 101 and is connected to the middle of the bracket 102. The cross-section of the lower end of the main shaft 104 is a toothed structure. A rotary table 105 is installed at the bottom of the worktable 1, and the output end of the rotary table 105 is slidably connected to the lower end of the main shaft 104. The rotary table 105 drives the clamp 103 on the bracket 102 to index and rotate the iron core through the main shaft 104.

[0034] A cylinder 106 is installed at the lower end of the rotary table 105. The cylinder 106 abuts against the bottom wall of the spindle 104 through a steel ball embedded in the top of its output end.

[0035] In this embodiment, cylinder 106 is first activated to push upward, so that cylinder 106 pushes the main shaft 104 and the output end of rotary table 105 to slide through the steel ball embedded in the output end. Since the cross-section of the lower end of the main shaft 104 is a toothed structure, the output end of rotary table 105, which slides with the lower end of the main shaft 104, can still drive the main shaft 104 to rotate when the main shaft 104 is raised and lowered.

[0036] When cylinder 106 pushes the spindle 104 and bracket 102 to a specified height, the rotary table 105 is activated to drive the spindle 104 to rotate inside the cylinder 101. The spindle 104 can then drive the gripper 103 on the outer edge of the bracket 102 to deflect at an intermittent angle. Each time the gripper 103 rotates, it will clamp the horizontally placed iron core through the "L"-shaped clamping part for multi-station transfer. When the rotary table 105 drives the gripper 103 to rotate to a predetermined angle, cylinder 106 will drive the output end to move down and reset. As a result, the bracket 102 will drive the spindle 104 to slide down and reset. Therefore, the gripper 103 will place the clamped iron core horizontally in the corresponding station, ensuring that the bracket 102 and the gripper 103 cooperate to achieve horizontal rotation and transfer of the iron core through height lifting and intermittent angle rotation.

[0037] Please see Figure 1 , Figure 3 and Figure 4 The outer periphery of the column cylinder 101 is provided with a feeding station 2, a support 3, a shaping station 5, a welding station 6, and a unloading station 7.

[0038] The loading station 2 includes a rotating block 201 rotatably connected to the upper side of the workbench 1. The rotating block 201 is pushed and pulled to rotate by a telescopic rod 202 that is horizontally hinged to the upper side of the workbench 1. A cylinder 203 with an output shaft passing through the rotating block 201 is installed at the bottom of the workbench 1. A receiving rod 204 is installed at the top of the output shaft of the cylinder 203. A guide rod parallel to the output shaft of the cylinder 203 is fixed on the upper surface of the rotating block 201, and the guide rod is slidably connected to the receiving rod 204.

[0039] In this embodiment, the receiving rod 204 is driven to descend to a predetermined height along the guide rod by the cylinder 203. Then, the rotating block 201 is pulled to rotate forward by the telescopic rod 202, which drives the receiving rod 204 away from the clamp 103. Conversely, the rotating block 201 is pushed to rotate in the opposite direction by the telescopic rod 202, which drives the receiving rod 204 closer to the clamp 103. In order to ensure that the rotating block 201 rotates to the corresponding position, two blocking blocks are installed at the predetermined positions of the rotating block 201 in the forward and reverse rotation to ensure that the rotating block 201 can be blocked and limited when it rotates forward and in the opposite direction to the corresponding position. When the rotating block 201 rotates in the opposite direction to the predetermined position, the end of the receiving rod 204 can be driven to be directly below the clamp 103 of the station.

[0040] Please see Figure 3 and Figure 4 Both the support 3 and the receiving rod 204 are equipped with positioning seats 8 for positioning and placing the iron core.

[0041] In this embodiment, cylinder 203 can drive the receiving rod 204 to descend, thereby causing the positioning seat 8 on the receiving rod 204 to descend and avoid clamp 103. Furthermore, rotating the positioning seat 8 away from clamp 103 can achieve the positioning and placement of the iron core. Conversely, cylinder 203 can drive the receiving rod 204 to rise, thereby causing the positioning seat 8 on the receiving rod 204 to rise closer to clamp 103. Therefore, the positioning seat 8 can drive the received iron core to the clamping area of ​​clamp 103.

[0042] When the receiving rod 204 rises to the predetermined height, the positioning seat 8 on the receiving rod 204 and the top positioning seat 8 of the support 3 are at the same height, ensuring that the iron core received by the feeding station 2 and the iron core placed on the support 3 are at the same height.

[0043] Please see Figure 1 and Figure 2 The workbench 1 is equipped with a plug-in station 4 corresponding to the support 3, which is used to plug in the short-circuit ring coil of the iron core placed above the support 3. The plug-in station 4 consists of a Y-axis module 401, an X-axis module 402 that moves along the Y-axis module 401, a Z-axis module 403 that moves laterally along the X-axis module 402, and a second clamp 404 that is raised and lowered by the Z-axis module 403. The clamping part at the bottom of the second clamp 404 is a flat plate structure. The second clamp 404 can stably clamp the short-circuit ring through the clamping part of the flat plate structure.

[0044] In this embodiment, the insertion station 4 moves back and forth via the Y-axis module 401, moves horizontally via the X-axis module 402, and moves up and down via the Z-axis module 403. This allows the clamping device 404 at the bottom of the Z-axis module 403 to grip the inverted U-shaped short-circuit ring at a designated position through the clamping part of the planar plate structure. When the reciprocating clamping device 404 grips the short-circuit ring multiple times, the insertion station 4 can insert the short-circuit ring into the short-circuit ring mounting hole of the iron core above the support 3 through the clamping device 404, thereby facilitating the pre-assembly and insertion of the short-circuit ring and the iron core. The three-axis linkage of the Y-axis module 401, X-axis module 402, and Z-axis module 403 of the insertion station 4 is prior art, and reference can be made to Chinese Patent No. CN206733051U.

[0045] Please see Figure 6 and Figure 9 The forming station 5 includes a bending mechanism 501 for forming the end of the short-circuit ring and a clamp 502 for flat supporting the iron core. A base is installed on the upper side of the workbench 1, and a cylinder 501a for driving the bending mechanism 501 to rise and fall is connected to the base.

[0046] The tail of the clamp 3 502 is connected to the output end of the motor 1 502a. The motor 1 502a is mounted on the workbench 1 via a mounting base. The front end of the clamping part of the clamp 3 502 is connected to a gasket 502b for abutting against the short-circuit ring to prevent the short-circuit ring from falling off the iron core.

[0047] In this embodiment, when the bracket 102 moves the iron core on the support 3 to the forming station 5 through the clamp 103, the cylinder 106 resets and drives the bracket 102 and the clamp 103 to move down. The clamping part of the clamp 3 502 will immediately clamp the iron core held by the clamp 103. At this time, when the clamp 103 releases the clamped iron core, the clamp 3 502 will press against the short-circuit ring from above through the pad 502b of the clamping part. Then, the motor 502a drives the clamp 3 502 to rotate 180° horizontally. At this time, the clamping part of the clamp 3 502 will flatly support and limit the short-circuit ring with the opening facing upward through the pad 502b rotated to the bottom of the iron core. This can prevent the short-circuit ring from falling off the iron core and can also stably support the iron core with the short-circuit ring horizontally through the clamp 3 502.

[0048] Please see Figures 6-8 The bending mechanism 501 for forming the end of the short-circuit ring includes a bearing seat 501e for abutting against the iron core from top to bottom. The bearing seat 501e is connected to the output end of the cylinder 501a. The bottom wall of the bearing seat 501e is integrally formed with a conical positioning pin 501b for positioning the circular holes on the opposite side of the iron core surface. A motor 501c is installed in the middle of the bearing seat 501e. The output end of the motor 501c is connected to a pressure plate 501d through a lead screw.

[0049] Two T-shaped rods 501d1 are respectively provided at both ends of the pressure plate 501d. One of the T-shaped rods 501d1 is telescopically connected to the top wall of the other T-shaped rod 501d1 through a spring 501d2. A slide rail 501d3 is installed in the bearing seat 501e. Two sets of guide blocks 501d4 with wide and narrow spacing are connected in the slide rail 501d3 to bend U-shaped short-circuit rings of different widths. The surfaces of the two sets of guide blocks 501d4 are provided with inclined grooves that slide and connect with the T-shaped rods 501d1.

[0050] In this embodiment, when the clamp 3 502 stably and horizontally lifts the iron core with the short-circuit ring, the cylinder 4 501a drives the bending mechanism 501 to a position close to the iron core. At this time, the positioning pin 501b on the bottom wall of the bearing seat 501e is inserted into the round hole on the opposite side of the iron core surface, so that the bending mechanism 501 and the iron core can be positioned and docked.

[0051] Then, the motor 501c drives the lead screw at the output end to thread the pressure plate 501d, causing the pressure plate 501d to press down on the two sets of T-shaped rods 501d1. Since one of the T-shaped rods 501d1 is connected to the top wall of the other T-shaped rod 501d1 via a spring 501d2, the downward-moving pressure plate 501d will first press the inclined groove of the wide-space guide block 501d4 through the first T-shaped rod 501d1 to bring them closer together. When the first T-shaped rod 501d1 moves down a certain distance and compresses the spring 501d2, The top of the first T-shaped rod 501d1 will press against the top of the second T-shaped rod 501d1. At this time, the first T-shaped rod 501d1, which continues to move downward, will simultaneously drive the second T-shaped rod 501d1 downward, so that the second T-shaped rod 501d1 will press against the inclined groove of the narrow-pitch guide block 501d4 to move closer. Thus, through the two sets of wide-pitch and narrow-pitch guide blocks 501d4, the ends of U-shaped short-circuit rings of different widths can be bent laterally, ensuring that U-shaped short-circuit rings of different widths can be bent quickly and fasten to the iron core.

[0052] Conversely, the motor 501c drives the lead screw at the output end to reverse the thread transmission with the pressure plate 501d, which enables the pressure plate 501d to drive the two sets of T-shaped rods 501d1 upward to press the two sets of wide and narrow guide blocks 501d4, so that the guide blocks 501d4 are reset.

[0053] Please see Figure 1 , Figure 3 and Figure 10 The welding station 6 consists of a laser welding gun 601 installed at an angle and a fixed seat 602 docked on the worktable 1. The top of the fixed seat 602 is provided with a rotating seat 602a with two protruding pins 602b on the top wall. A motor 602c is installed inside the fixed seat 602 to drive the rotating seat 602a to rotate in a circular motion.

[0054] In this embodiment, when the clamp 103 on the bracket 102 rotates the iron core at the shaping station 5 above the fixed seat 602, the downward-moving bracket 102 will place the iron core with the bent short-circuit ring on the rotating seat 602a through the clamp 103. The two protrusions 602b on the top wall of the rotating seat 602a are positioned and connected with the two round holes on the surface of the iron core, so that the iron core can be positioned on the rotating seat 602a. This makes it convenient for the inclined laser welding gun 601 to weld the end joint gap of one of the short-circuit rings. Then, the rotating seat 602a can be rotated by the motor 602c to drive the iron core with the short-circuit ring to deflect at an angle, so that the joint gap of the remaining short-circuit rings can be welded, ensuring that the welding station 6 can weld the connection gap of the short-circuit rings to conduct electricity.

[0055] Please see Figure 1 and Figure 3 The unloading station 7 uses a belt conveyor to export the completed welded and assembled iron core. When the rotating bracket 102 drives the clamp 103 to move the completed welded and assembled iron core to the unloading station 7, the unloading station 7 of the belt conveyor can export the iron core. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
