Description

Technical Field

[0001] This utility model belongs to the technical field of soldering equipment, and in particular relates to a varistor soldering equipment for IPM iron core motor rotor assembly. Background Technology

[0002] A motor, also known as an electric motor or engine, rotates a starter rotor by means of an energized coil rotating in a magnetic field. A small gear on the rotor drives the engine flywheel, which in turn rotates the crankshaft to start the engine. Innovations include a new type of low-cost spark plug with a ceramic core base and a starter. The iron-core motor rotor assembly includes a rotor and a varistor. Currently, the varistor is typically welded to the rotor manually. This involves first fitting the varistor onto the rotor and then welding it in place. This traditional production method is not only inefficient and costly in terms of labor, but also prone to incomplete soldering between the varistor and the rotor. Utility Model Content

[0003] In view of the fact that the traditional production methods mentioned above are not only inefficient and costly, but also prone to problems such as missing solder joints between the varistor and the rotor, this utility model provides a varistor soldering device for IPM core motor rotor assembly.

[0007] Preferably, the clamping assembly includes clamping plates, first springs, and movable columns. There are two clamping plates, and two sets of first springs and movable columns. The two sets of first springs are respectively fixed to the two clamping plates and the inner wall of the through groove, and the two sets of movable columns are respectively fixed to the two clamping plates.

[0008] Preferably, the soldering assembly includes a bracing plate, an electric push rod, and a soldering head. The bracing plate is fixed to a fixed plate, the electric push rod is fixedly mounted on the bracing plate, and the output end of the electric push rod is fixed to the soldering head.

[0009] Preferably, a second spring is fixedly provided on the inner side of the sleeve, and the pressure block is fixed to the bottom end of the second spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The motor drives the first rotating shaft to rotate, which in turn drives the first turntable and the first synchronous pulley to rotate. The first synchronous pulley drives the second synchronous pulley to rotate via a synchronous belt, which in turn drives the second turntable to rotate. When the first and second turntables rotate to their corresponding positions, the pressure block presses down on the corresponding varistor, causing the varistor to detach from the two clamping plates. The electric push rod then moves the solder head forward to perform soldering. By rotating the first and second turntables by a fixed angle each time, the soldering process is performed continuously.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 A pressure-sensitive soldering device for an IPM core motor rotor assembly includes a workbench 1, on which a first rotating shaft 2 and a second rotating shaft 3 are rotatably mounted. A first turntable 4 is fixedly mounted at the top of the first rotating shaft 2, and a second turntable 5 is fixedly mounted at the top of the second rotating shaft 3. A motor 6 is fixedly mounted at the bottom of the workbench 1, and the output end of the motor 6 is fixed to the first rotating shaft 2. A transmission assembly is provided between the first rotating shaft 2 and the second rotating shaft 3. The transmission assembly includes a first synchronous pulley 16, a second synchronous pulley 17, and a synchronous belt 18. The first synchronous pulley 16 is fixedly mounted on the first rotating shaft 2, and the second synchronous pulley 17 is fixedly mounted on the second rotating shaft 3. The first synchronous pulley 16 and the second synchronous pulley 17 are connected by the synchronous belt 18.

[0019] The first turntable 4 has multiple placement slots 7, and the second turntable 5 has multiple through slots 8 that are adapted to the placement slots 7.

[0020] Specifically, by placing the rotor in multiple placement slots 7, the motor 6 drives the first rotating shaft 2 to rotate, the first rotating shaft 2 drives the first rotating disk 4 and the first synchronous pulley 16 to rotate, the first synchronous pulley 16 drives the second synchronous pulley 17 to rotate via the synchronous belt 18, and the second synchronous pulley 17 drives the second rotating disk 5 to rotate, so that the first rotating disk 4 and the second rotating disk 5 rotate at a fixed angle.

[0021] Furthermore, clamping components are provided in multiple through slots 8 on the second turntable 5. The clamping components include clamping plates 19, first springs 20, and movable columns 21. There are two clamping plates 19, and two sets of first springs 20 and movable columns 21. The two sets of first springs 20 are fixed to the two clamping plates 19 and the inner wall of the through slots 8, respectively. The two sets of movable columns 21 are fixed to the two clamping plates 19, respectively. By placing the varistor in the through slot 8, the two clamping plates 19 clamp the varistor under the restoring force of the two sets of first springs 20.

[0022] In addition, an L-shaped frame 9 is fixedly installed on the workbench 1. A hydraulic rod 10 is fixedly installed on the upper end of the L-shaped frame 9. A sleeve 11 is fixedly installed at the output end of the hydraulic rod 10. A pressure block 12 is installed at the bottom end of the sleeve 11. A second spring 25 is fixedly installed inside the sleeve 11. The pressure block 12 is fixed to the bottom end of the second spring 25. The output end of the hydraulic rod 10 drives the sleeve 11 to move downward, which in turn drives the pressure block 12 to move downward, so that the pressure block 12 presses down on the corresponding varistor, causing the varistor to detach from the two clamps 19 and be placed on the upper end of the rotor. By setting the second spring 25, the pressure block 12 will not excessively press the varistor.

[0023] In addition, a fixing plate 13 is fixedly installed on the side end of the L-shaped frame 9. A soldering assembly is installed on the fixing plate 13. The soldering assembly includes a diagonal brace 22, an electric push rod 23, and a soldering head 24. The diagonal brace 22 is fixed to the fixing plate 13, and the electric push rod 23 is fixedly installed on the diagonal brace 22. The output end of the electric push rod 23 is fixed to the soldering head 24.

[0024] Finally, four support pillars 14 are fixedly installed at the bottom of the workbench 1, and each of the four support pillars 14 is equipped with a self-locking wheel 15 at its bottom. By setting the self-locking wheel 15, it is convenient to move the entire device.

[0025] The operating principle of this utility model is described as follows: By placing the rotor in multiple placement slots 7 and then placing the varistor in the through slot 8, the two clamping plates 19 clamp the varistor under the restoring force of the two sets of first springs 20. The motor 6 drives the first rotating shaft 2 to rotate, which in turn drives the first rotating disk 4 and the first synchronous wheel 16 to rotate. The first synchronous wheel 16 drives the second synchronous wheel 17 to rotate via the synchronous belt 18, which in turn drives the second rotating disk 5 to rotate. When the first rotating disk 4 and the second rotating disk 5 rotate to the corresponding positions, the output end of the hydraulic rod 10 drives the sleeve 11 to move downward, which in turn drives the pressure block 12 to move downward. The pressure block 12 presses down on the corresponding varistor, causing the varistor to detach from the two clamping plates 19 and be placed on the upper end of the rotor. The electric push rod 23 drives the solder head 24 to move forward for soldering. By rotating the first rotating disk 4 and the second rotating disk 5 by a fixed angle each time, the soldering process is performed continuously.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
