Detailed Implementation

[0019] 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.

[0020] Example 1 like Figure 1-8 As shown, a training assembly device for circuit board assemblies includes a workbench 1, a feeding mechanism 2, a picking mechanism 3, a welding mechanism 4, a screw-locking mechanism 1 5, a screw-locking mechanism 2 6, and a unloading mechanism 7. The picking mechanism 3 is located in the middle of the workbench 1 and is used to transport materials between the feeding mechanism 2, the welding mechanism 4, and the unloading mechanism 7. The feeding mechanism 2, the welding mechanism 4, the screw-locking mechanism 2 6, and the unloading mechanism 7 are arranged around the picking mechanism 3. The feeding mechanism 2 is used to feed materials to be assembled (circuit boards and end caps). The welding mechanism 4 is used for soldering or simulating soldering of circuit boards. The screw-locking mechanism 1 5 is located between the welding mechanism 4 and the screw-locking mechanism 2 6 and is used to fix the circuit board. The unloading mechanism 7 is used to feed and unload semi-finished motor products and cooperates with the picking mechanism 3 to install the end cap. The screw-locking mechanism 2 6 is located above the unloading mechanism 7 and is used to fix the end cap.

[0021] like Figure 1 As shown, the top of the workbench 1 is equipped with an outer frame for covering the equipment. The outer frame has a transparent door panel, which is aesthetically pleasing, clean and safe during the assembly process, and has a high level of safety. The bottom of the workbench 1 is equipped with a control box for centralized control.

[0022] This invention can operate in two modes: training mode and production mode. In training mode, the welding mechanism 4 mainly simulates soldering, and the circuit board being fed is a pre-soldered circuit board. In a few cases, the circuit board being fed is the circuit board substrate, and the welding mechanism 4 automatically solders it, allowing students to observe and learn the circuit board manufacturing process. In production mode, the circuit board being fed is a pre-manufactured circuit board, which is directly installed on the semi-finished motor without soldering, thus improving production efficiency.

[0023] This invention features a reasonable and compact structure with an attractive appearance. It can automatically assemble circuit board components, achieving a high degree of automation and improving assembly efficiency and quality. Furthermore, it adopts both training and production operation modes, facilitating practical teaching and enhancing students' understanding of articulated motors and bionic robots. It is suitable for both industrial production and practical teaching.

[0024] like Figure 2-3 As shown, the feeding mechanism 2 includes a first feeding component 21 and a second feeding component 22 arranged side by side on one side of the workbench. The first feeding component 21 includes a transfer conveyor belt 211 and a first material tray 212 disposed on the transfer conveyor belt 211. The second feeding component 22 includes a transfer conveyor belt 211 and a second material tray 221 disposed on the transfer conveyor belt 211.

In addition, the feeding mechanism 2 also includes a transfer platform 23, which is disposed on the side of the second feeding component 22 near the unloading mechanism 3, for temporarily storing the materials loaded on the second feeding component 22 to improve feeding efficiency.

[0025] like Figure 2-3 As shown, the material handling mechanism 3 includes at least one robot 31. Each robot 31 has a corresponding quick-change bracket 32 ​​on one side. The output end of the robot 31 is movably connected to multiple material handling grippers on the corresponding quick-change bracket 32. In this embodiment, two robots are provided, which can work alternately to improve production efficiency.

[0026] like Figure 1-3 As shown, the unloading mechanism 7 includes a platform conveyor belt 71 and a tray 72. One end of the platform conveyor belt 71 is located on the workbench 1, and the other end is connected to the conveyor line 73 located outside the workbench 1. The tray 72 is provided with at least one positioning platform, which is used to position and load the motor semi-finished product. The platform conveyor belt 71 unloads and loads the motor semi-finished product through the conveyor tray 72.

[0027] like Figure 2-4As shown, the welding mechanism 4 includes a conveying component 41, a soldering component 42, and a temporary storage platform 43. The conveying component 41 is located outside the material handling mechanism 3 and is used to convey and store circuit boards to be soldered. In this embodiment, the conveying component 41 is a narrow conveyor belt. The soldering component 42 is located at the discharge end of the conveying component 41 and is used for soldering or simulating soldering of circuit boards. It includes a soldering gun, a digital solder breaker, and a temperature controller. The temporary storage platform 43 is located between the conveying component 41 and the soldering component 42. The temporary storage platform 43 is provided with multiple positioning seats for temporarily storing motor semi-finished products, including motor semi-finished products with unassembled circuit boards and assembled motor semi-finished products. In addition, multiple ionizers 44 are provided on the side of the temporary storage platform 43 away from the conveying component 41 to purify the air and eliminate electrostatic interference, preventing electrostatic accumulation from damaging electronic components on the circuit board and improving welding safety.

[0028] like Figure 5 As shown, the screw-locking mechanism 5 includes a screw-locking assembly 51, which includes a screw-locking mounting base 511, a linear module 512, a linear module 513, a lifting assembly 514, and a screw gun 515. The screw-locking mounting base 511 is located above the workbench 1, with the linear module 512 at its upper end. The moving end of the linear module 512 has the linear module 513 arranged perpendicularly thereto, and the moving end of the linear module 513 has the lifting assembly 514. The moving end of the lifting assembly 514 has the screw gun 515. In this embodiment, the linear modules 512 and 513 are both linear movement structures combining a lead screw and a slide rail, and the lifting assembly 514 is a linear movement structure combining a cylinder and a slide rail, but it is not limited to these.

[0029] like Figure 2-7 As shown, the screw-locking mechanism 5 also includes a conveying component 2 52, which is located between the soldering component 42 and the screw-locking component 51. It includes a linear module 3 521 and a fixture 53 located at the moving end of the linear module 3 521. The fixture 53 is used to position the motor semi-finished product and the circuit board. It includes a fixture base plate 531 and a positioning base 532, a quick clamp 533, and a pressure cover assembly located above the fixture base plate 531. The positioning base 532 has a positioning hole for positioning the motor semi-finished product, and a positioning pin is provided in the positioning hole to position the circumferential position of the motor semi-finished product. The pressure cover assembly is located on one side of the positioning base 532 and is used to position the circuit board. The quick clamp 533 is located on the other side of the positioning base 532 and is used to hold the pressure cover assembly. The quick clamp 533 and the pressure cover assembly cooperate to elastically hold the circuit board above it.

[0030] In the above structure, such as Figure 6-7As shown, the cap assembly includes a cap rotating seat 534, a cap 535, positioning blocks 536, and a pressure rod 537. The cap rotating seat 534 is fixed to one side of the tooling base plate 531, and its upper end is provided with a cap 535 rotatably connected to it. A tension spring 538 connected to the cap is also provided on one side of the cap rotating seat 534. The bottom surface of the cap 535 is provided with multiple positioning blocks 536 corresponding to openings on the circuit board. Each positioning block 536 is at least partially inserted into the corresponding opening on the circuit board. Multiple positioning blocks 536 position the circuit board circumferentially, preventing rotation and displacement during transport. The pressure cover 535 has openings corresponding to the screw positions. The bottom surface of the pressure cover 535 also has multiple elastic pads 539. These pads 539 press down on blank areas of the circuit board when the pressure cover 535 is pressed down, reducing the pressure area and minimizing damage to the circuit board. The top surface of the pressure cover 535 also has a pressure rod 537. The handle of the quick clamp 533 has an arc-shaped pressing part that cooperates with the pressure rod 537. Furthermore, a locking block 5310 is located at the end of the pressure cover 535 away from the pressure cover rotating seat 534. A locking block seat 5311 is located on the side of the positioning base 532 near the quick clamp 533. The top of the locking block seat 5311 has a latching part that cooperates with the locking block 5310. By configuring the locking block 5310 and locking block seat 5311, the position of the pressure cap 535 can be initially positioned before the quick clamp 533 presses it in place. Furthermore, it prevents the pressure cap from springing open directly under the action of the tension spring when the quick clamp is released, thus improving operational safety and stability. In summary, the pressure cap assembly can accurately position the circuit board while minimizing damage to it.

[0031] Example 2 Based on the structure of Example 1, such as Figure 2-3 and Figure 8 As shown, the screw-locking mechanism 26 includes a screw-locking assembly 261, which includes a screw-locking mounting base 2611, a linear module 4 612, a linear module 5 613, a lifting assembly 2 614, and a screw gun 2 615.

The moving end of the linear module 4 612 is provided with a horizontal support plate 616. The horizontal support plate 616 is provided with a linear module 5 613 that is perpendicular to the linear module 4 612. The moving end of the linear module 5 613 is provided with a linear module 617 that is perpendicular to it. The moving end of the linear module 617 is provided with a lifting assembly 2 614, and the moving end of the lifting assembly 2 614 is provided with a screw gun 2 615.

[0032] In this embodiment, linear modules 612 and 613 are linear movement structures combining lead screws and slide rails, while linear module 617 and lifting assembly 614 are linear movement structures combining cylinders and slide rails, but are not limited to these. Linear modules 612, 613, and 617 enable the screw gun 615 to move in the XYZ directions, providing good flexibility.

[0033] The screw-locking mechanism 6 also includes a guide assembly 62, which includes a guide support 621 and a lifting cylinder 622. The guide support 621 is arranged parallel to the horizontal support plate 616, and the lifting cylinder 622 is located on the side of the guide support 621 closest to the horizontal support plate 616. The output end of the lifting cylinder 622 is provided with a guide seat 623, which is correspondingly arranged with the screw gun 615 to guide the screw-locking position of the screw gun 615. When locking the screw, the semi-finished motor on the tray to be locked moves to directly below the guide seat 623. The guide seat 623 has openings corresponding to the screw-locking positions on the end cap, guiding the screw gun 615 to lock the screw-locking end cap.

[0034] In addition, such as Figure 2-3 As shown, two screw feeders 63 are arranged side by side above the workbench 1. The two screw feeders 63 are located close to the screw fastening assembly 61. The two screw feeders 63 are connected to screw gun 1 515 and screw gun 2 615 respectively through the feeding pipe to feed screw gun 1 515 and screw gun 2 615.

Assembling the circuit board includes the following steps: S21, Soldering: The material handling mechanism 3 picks up the circuit board and places it onto the conveying component 41 in sequence. Then, the robot 31 works with the soldering component 42 to complete the soldering of the circuit board. At the same time, the material handling mechanism 3 places the semi-finished motor into the temporary storage table 43. S22. Assembly: The material handling mechanism 3 places the semi-finished motor and the welded circuit board onto the tooling 53 of the screw-locking mechanism 5. The tooling 53 clamps and positions the semi-finished motor and the circuit board. The screw-locking assembly 51 locks the screws to fix the circuit board onto the semi-finished motor. Then, the material handling mechanism 3 places the assembled semi-finished motor onto the unloading mechanism 7. S3. Assemble the end cap.
