Description

Technical Field

[0001] This utility model relates to the field of tin-immersion equipment technology, and in particular to an automatic tin-immersion testing machine. Background Technology

[0002] A motor, also known as an electric motor, is an electrical device that converts electrical energy into mechanical energy, which can then be used to generate kinetic energy to drive other devices. There are many types of electric motors, but their basic structure consists of a stator and a rotor. The stator is stationary in space, while the rotor rotates around its axis and is supported by bearings. There is a certain air gap between the stator and rotor to ensure the rotor can rotate freely. When coils are wound around the stator and rotor and current is passed through them, a magnetic field is generated, creating an electromagnet. With the rapid development of the electronics, electrical appliances, and industrial equipment industries, a wide variety of electrical appliances are available, with diverse functions and applications. The realization of most of these functions relies on the use of electric motors, making them one of the most important electrical components in modern industrial technology. The manufacturing process of motors is complex; the production of the motor stator alone involves multiple steps. To facilitate subsequent assembly and further processing, the pins on the pin holders of the motor stator frame need to be tinned. Current technology involves manually placing the stator into a tinning furnace, which results in slow operation, low production efficiency, increased labor costs, and negatively impacted economic benefits for enterprises. Therefore, most stators are now tinned using fully automatic or semi-automatic tinning equipment.

[0003] For example, a motor stator tin-dipping testing integrated device with patent number CN201820255558.8 uses an automatic tin-dipping method. Although this solves the problem of low automation, the process of handling and transferring the stator in this solution is relatively complex, resulting in low production efficiency. Therefore, there is an urgent need for a new type of tin-dipping machine to solve the above problems. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] like Figure 1-3 As shown, the automatic tin-dipping tester of this utility model includes a frame 1, a worktable 2 and a protective cover 3, as well as an automatic tin-dipping test mechanism set on the worktable. The worktable 2 is provided with a motor 21 and a turntable 22. The output shaft of the motor 21 is connected to the middle of the turntable 22 to drive the turntable 22 to rotate. The edge of the turntable is provided with multiple sets of grippers 23.

[0027] This utility model discloses an automatic tin-dipping testing mechanism, which mainly includes a frame 1, a worktable 2, a protective cover 3, and the automatic tin-dipping testing mechanism itself. The worktable 2 is mounted on the frame 1 to support the automatic tin-dipping testing mechanism, and the protective cover is located on the outside of the worktable 2 for safety protection. A motor 21 and a turntable 22 are located in the center of the worktable 2. Multiple sets of grippers 23 are arranged along the edge of the turntable, specifically eight sets of grippers 23. Each gripper can hold one stator 100. During processing, the motor 21 drives the turntable 22 to rotate, which in turn rotates the stator on the grippers 23, moving it to the designated workstation for the corresponding processing operation. This ensures that the stator is easily and conveniently handled and transferred during processing, further improving processing efficiency.

[0028] Reference Figure 2 and Figure 3 The automatic tin-dipping test mechanism of the automatic tin-dipping test machine includes eight stations: loading station 4, flux dipping station 5, tin dipping station 6, cooling station 7, two testing stations 8, defective product removal station 9, and unloading station 10. These stations are arranged around the turntable 22 in sequence, and each station corresponds to a set of grippers 23, which can be operated simultaneously.

[0029] The loading station 4 is located directly in front of the workbench 2, allowing for manual or automated loading by a robotic arm. The loading station 4 is equipped with a loading base 41, a drive motor 42, and a material tray 43. The loading base 41 is located on the workbench 2, and the drive motor 42 is located on the loading base 41. Its output shaft is connected to the center of the material tray 43, driving the tray 43 to rotate. The material tray 43 is octagonal and can hold eight stators 100. A set of grippers 23 clamps two stators at a time for tinning. The material tray 43 can rotate. When a stator near the grippers is removed, the drive motor 42 drives the material tray 43 to rotate, and the motor 21 drives the turntable 22 to rotate, causing the stator on the other side of the material tray 43 to rotate to the position of the previous set of stators. Simultaneously, the grippers 23 also rotate to the position of the previous set of grippers, continuing to clamp and tin-dip the stators, ensuring continuous loading and high production efficiency.

[0030] The flux immersion station 5 is equipped with a support 51 and a flux storage box 52 mounted on the support. A cylinder 53 is located on the outside of the flux storage box 52. A first lifting plate 54 is mounted on the telescopic rod of the cylinder 53, and a flux box 55 is connected to the first lifting plate 54. Flux is placed inside the flux storage box 52 of the flux immersion station 5. The flux box 55 is located inside the flux storage box 52 via the first lifting plate 54. When the stator that needs to be immersed in flux rotates to this station, the cylinder 53 drives the first lifting plate 54 and the flux in the flux box 55 to rise to the bottom of the stator pins for immersion. After immersion, the cylinder 53 drives the first lifting plate 54 and the flux box 55 to descend to the designated position to wait for the next set of stators to be immersed. The operation is simple and convenient.

[0031] The tin-dipping station 6 is equipped with a tin-dipping base 61, a tin-dipping furnace 62, and a lifting mechanism 63.

The upper end of the lifting mechanism 63 is equipped with a second lifting plate 64, and a solder box 65 is connected to the second lifting plate 64. The tin-dipping furnace 62 in this tin-dipping station contains solder flux, and the solder box 65 is located inside the tin-dipping furnace 62 via the second lifting plate 64. When the stator to be tinned rotates to this station, the lifting mechanism 63 drives the second lifting plate 64 and the solder flux in the solder box 65 to rise to the bottom of the stator pins for immersion. After immersion, the lifting mechanism drives the second lifting plate 64 and the solder box 65 to descend to the designated position to wait for the next set of stators to be tinned. The operation is simple and convenient. It should be noted that the lifting mechanism 63 can adopt an existing linear module or other existing lifting device, which is not limited here and will not be described in detail.

[0032] Cooling station 7 is equipped with a cooling base and a coolant box 71, with the coolant box 71 located on the cooling base; testing station 8 is equipped with a testing bracket, with a drive cylinder and a tester mounted on the testing bracket 81; defective product removal station 9 is also equipped with [missing information]. Cooling station 7 is used to cool the stator after tinning; there are two testing stations 8 to ensure double testing of the tinned stator, guaranteeing a high yield rate. If the flux and solder coating are incomplete, or if there is a partial lack of solder, it will affect the quality of the finished motor stator, thus it is judged as a defective product and placed in the defective product collection box 91 for recycling.

[0033] This automatic tin-dipping tester can run eight stations at once, eliminating the problem of insufficient or missing materials, ensuring high tin-dipping efficiency and good results, and improving the quality of finished stator products.

[0034] In a preferred embodiment, refer to Figure 2 and 3The automatic tin-dipping testing machine has an octagonal turntable 22 with a set of grippers 23 on each side, each gripper 23 holding two stators 100 to be tin-dipped. The material tray 43 is also octagonal, with four sets of stators 100 to be tin-dipped placed on its sides. The stators are placed on the mounting holes of the material tray by a robotic arm or a feeding device. Specifically, the grippers 23 on the turntable 22 are used to hold the stators 100 to be tin-dipped, and a rotary process is used to transfer and transport the stators, ensuring that stators are operated at each station, thus guaranteeing the processing efficiency of the stators.

[0035] In a preferred embodiment, refer to Figure 2 and 3 The first lifting plate 54 and the second lifting plate 64 of the automatic tin-dipping tester are both "7" shaped.

The storage box 13 is located at the bottom of the frame and is used to store items used in production and processing.

[0037] The working principle of this automatic tin-immersion testing machine is as follows:

[0038] The drive motor 42 of the loading station 4 drives the material tray 43 to rotate, and the motor 21 in the middle of the worktable 2 drives the turntable 22 to rotate, so that the grippers 23 on the turntable 22 hold a set of stators 100 to the flux immersion station 5. After the stators are immersed in flux, the turntable 22 continues to drive the stators to the tin immersion station 6. After the tin immersion is completed, the turntable 22 continues to drive the stators to the cooling station 7. After the stators are cooled, the turntable 22 continues to drive the stators to the testing station 8. There are two testing stations. After the stators are tested, the defective products are carried to the defective product removal station 9, and the qualified products are carried to the unloading station 10 for collection. During the rotation of the turntable 22, the grippers 23 on the turntable 22 will continuously hold the stators to perform the above operations, ensuring the production efficiency of the tin immersion machine.
