[0038] In one embodiment of the present invention, Figures 1 to 10As shown, a production and testing line for a flat transformer is provided, which includes an assembly jig 10, a front-end assembly line 20, a middle-end assembly line 30, a rear-end test line 40 and a width-adjustable conveying device 50. An installation station is provided on the assembly jig 10; the front-end assembly line 20 includes a magnetic core assembly device 21 for loading and assembling a magnetic core on the assembly jig 10 to form a workpiece, a PCB mounting device 22 for loading and assembling a PCB board on the workpiece, a glue dispensing device 23 for dispensing glue on the workpiece and a magnetic core scraping glue assembly device 24 for scraping glue on the magnetic core after dispensing glue; the assembly jig 10 passes through the magnetic core assembly device 21, the PCB mounting device 22, the glue dispensing device 23 and the magnetic core scraping glue assembly device 24 in sequence; the middle-end assembly line 30 includes an automatic sheath assembly station 31 for loading and assembling a sheath on a workpiece, a body assembly station 32 for loading and assembling a body on a workpiece and a cover loading and assembling station 24 for loading and assembling a cover. An upper cover assembly station 33 for assembling the upper cover on the workpiece to form a product; an automatic assembly sleeve station 31, a main body assembly station 32 and an upper cover assembly station 33 are arranged in sequence; the final test line 40 includes a test fixture 41 for placing products, a horizontal reflux conveying device 42 for conveying the test fixture 41, a laser coding scanner 43 for coding the product on the test fixture 41 and scanning the code to generate a corresponding product identification code, an inspection station 44 for inspecting the product and a discharge device 45 for classifying and unloading the inspected products; the front-end assembly line 20 and the middle-end assembly line 30 are both provided with a width-adjustable conveying device 50; the width-adjustable conveying device 50 is used to convey the assembly fixture 10.

[0039] Specifically, the assembly jig 10 is the core part of the production line, which is used to fix and support the workpiece to ensure the stability and accuracy of the workpiece during the assembly process. The assembly jig 10 is provided with an installation station for carrying and positioning the workpieces transported by each station. The assembly jig 10 passes through the core assembly device 21, the PCB installation device 22, the glue dispensing device 23 and the core scraping glue assembly device 24 on the front assembly line 20 to complete the preliminary assembly of the workpiece. The assembled workpiece passes through the width-adjustable conveying device 50 and enters the automatic assembly sheath station 31, the body assembly station 32 and the upper cover assembly station 33 of the middle assembly line 30 in turn to complete the final assembly of the product. The assembled products enter the final test line 40 through the width-adjustable conveying device 50 for testing and coding and scanning. The qualified products are classified and unloaded through the unloading device 45 to complete the entire production test process.

[0040] In the front-end assembly line 20, the magnetic core assembly device 21 automatically loads the magnetic core and accurately assembles it onto the assembly fixture 10 to form the basic structure of the workpiece. After the magnetic core is assembled, the PCB installation device 22 automatically loads the PCB board and assembles it onto the workpiece to achieve circuit connection. The glue dispensing device 23 performs glue dispensing on the assembled workpiece to fix the PCB board and other components. After dispensing, the magnetic core scraping glue assembly device 24 scrapes the magnetic core to ensure that the colloid is evenly distributed, thereby improving the assembly quality and the sealing of the product.

[0041] In the middle assembly line 30, the automatic jacket assembly station 31 automatically loads and assembles the jacket onto the workpiece to provide additional protection and insulation. The body assembly station 32 automatically loads and assembles the body onto the workpiece to complete the assembly of the main structure. The upper cover assembly station 33 automatically loads and assembles the upper cover onto the workpiece to form the final product.

[0042] In the final test line 40, the test fixture 41 is used to place the assembled products for subsequent testing. The horizontal reflux conveyor 42 is used to convey the movement of the test fixture 41 on the production line to ensure that the product enters the test phase smoothly. The laser code scanner 43 codes and scans the product to generate the corresponding product identification code for easy product tracking and management. The inspection station 44 performs quality inspection on the product to ensure that the product meets the quality standards. Unloading device 45: Classify and unload the qualified products for packaging or shipment.

[0043] Automated assembly and testing lines reduce manual operations and significantly improve production efficiency. Automated assembly and testing processes reduce human errors and improve product consistency and reliability. The width-adjustable conveyor 50 can be adjusted according to different product sizes, improving the adaptability and flexibility of the production line. The product identification code generated by the laser coding scanner 43 facilitates product tracking and management, improving the efficiency of production management. The compact production line layout saves production space and reduces production costs. Automated operation reduces the chances of workers directly contacting dangerous parts and improves workplace safety.

[0044] In this example, a baking device 60 is provided between the front-end assembly line 20 and the middle-end assembly line 30, and between the middle-end assembly line 30 and the final test line 40, for drying the workpiece on the assembly jig 10. Specifically, after the workpiece is initially assembled on the front-end assembly line 20, it will be transported to the baking device 60 for drying. After baking, the workpiece will be transported to the middle-end assembly line 30, and after the workpiece completes all assembly steps on the middle-end assembly line 30, it will enter the baking device 60 again for drying. After drying, the workpiece will be transported to the final test line 40 for subsequent processing such as product quality inspection and coding and scanning. The main working principle of the baking device 60 is to use thermal energy to dry the workpiece on the assembly jig 10. In this process, the baking device 60 generates heat through the heating element, and the heat is evenly distributed through the hot air circulation system to ensure that all parts of the workpiece can be fully dried.

[0045] In this example, the width-adjustable conveying device 50 includes a first conveying mechanism 51 and a second conveying mechanism 52 with opposite conveying directions, and the first conveying mechanism 51 is arranged above the second conveying mechanism 52; the length of the first conveying mechanism 51 is less than the length of the second conveying mechanism 52. Specifically, the design of the width-adjustable conveying device 50 allows it to adapt to assembly jigs 10 and workpieces of different sizes. The device is composed of two conveying mechanisms, a first conveying mechanism 51 and a second conveying mechanism 52, which have opposite conveying directions. The first conveying mechanism 51 is located above the second conveying mechanism 52, which can save space and allow a more flexible layout. The length of the second conveying mechanism 52 is longer than the first conveying mechanism 51, and is used to receive (manually or by setting mechanical equipment) the assembly jig 10 used by the first conveying mechanism 51.

[0046] In this example, the first conveying mechanism 51 includes a fixed bracket 511, a first conveying component 512, a second conveying component 513, a driving element 514 and a width adjustment module 515; the first conveying component 512 and the second conveying component 513 are arranged on the width adjustment module 515 in parallel and at intervals, and a conveying position for conveying the assembly jig 10 is formed between the first conveying component 512 and the second conveying component 513; the width adjustment module 515 is arranged on the fixed bracket 511, and is used to adjust the spacing between the first conveying component 512 and the second conveying component 513; the driving element 514 is used to drive the first conveying component 512 and the second conveying component 513 to operate and realize conveying. Specifically, the two conveying components are arranged on the width adjustment module 515 in parallel and at intervals, and a conveying position for conveying the assembly jig 10 is formed between them. These conveying components may be composed of a series of rollers, chains or belts, which can carry and move the assembly jig 10. This module is mounted on a fixed bracket 511, allowing the spacing between the first conveying component 512 and the second conveying component 513 to be adjusted to accommodate assembly jigs 10 of different widths. A driving element 514 (such as a motor and a gear system) is used to drive the operation of the first conveying component 512 and the second conveying component 513 to achieve the conveying of the assembly jig 10.

[0047] In this example, the width adjustment module 515 includes a mounting base 5151, a moving plate 5152, a screw 5153 and a turntable 5154; the mounting base 5151 is fixed on the fixed base 5311 bracket; the first conveying assembly 512 is mounted on the mounting base 5151, and the second conveying assembly 513 is mounted on the moving plate 5152; the screw 5153 is rotatably connected to the mounting base 5151, and the moving plate 5152 is threadedly connected to the screw 5153; and the turntable 5154 is connected to the screw 5153. Specifically, the mounting base 5151 is fixed on the fixed bracket 511 to provide a stable mounting base for the width adjustment module 515. The second conveying assembly 513 is mounted on the moving plate 5152, and the moving plate 5152 can move on the thread of the screw 5153, thereby changing the spacing between the second conveying assembly 513 and the first conveying assembly 512. The screw rod 5153 is rotatably connected to the mounting base 5151, and the rotation of the screw rod 5153 causes the movable plate 5152 to move along the thread of the screw rod 5153, thereby adjusting the spacing between the first conveying assembly 512 and the second conveying assembly 513. The turntable 5154 is connected to the screw rod 5153, and the operator can drive the rotation of the screw rod 5153 by rotating the turntable 5154, thereby controlling the position of the movable plate 5152 and adjusting the spacing between the conveying assemblies. The threaded connection mode of the movable plate 5152 and the screw rod 5153 makes the adjustment mechanism compact and occupies little space, which is suitable for a production line environment with limited space. The mechanical connection mode of the screw rod 5153 and the turntable 5154 is relatively simple and durable, reducing the risk of production line shutdown caused by failure of the adjustment mechanism. Since the structure of the width adjustment module 515 is relatively simple, the maintenance and replacement costs are low, which helps to reduce the overall production cost.

[0048] In this example, the width-adjustable conveying device 50 further includes a lifting mechanism 53, which includes a lifting component 531, a detection sensor 532, and a stop component 533; the lifting component 531 is installed below the first conveying mechanism 51 and is used to separate the assembly jig 10 from the conveying surface of the first conveying mechanism 51; the detection sensor 532 and the stop component 533 are electrically connected; after the detection sensor 532 detects that the assembly jig 10 has passed, one end of the stop component 533 moves upward and prevents the assembly jig 10 from moving. Specifically, the detection sensor 532 is arranged at one end of the lifting component 531 along the conveying direction, and is used to detect the position of the assembly jig 10 to ensure the accuracy of the lifting action. The stop component 533 is located at the other end of the detection sensor 532. When the detection sensor 532 detects that the assembly jig 10 has passed, one end of the stop component 533 moves upward to prevent the assembly jig 10 from moving further, so as to prevent the jig conveyed behind from affecting the jig in front from being lifted in the correct position. The lifting assembly 531 is electrically connected to the detection sensor 532 and the stop assembly 533 to form a control loop to ensure the coordination and accuracy of the lifting action. The detection sensor 532 and the stop assembly 533 are sequentially arranged at both ends of the lifting assembly 531 along the conveying direction to ensure the sequential execution of the lifting action.

[0049] In this example, the lifting assembly 531 includes a fixed seat 5311, a lifting cylinder 5312 and a lifting plate 5313. The fixed seat 5311 is installed on the first conveying mechanism 51, the lifting cylinder 5312 is installed on the fixed seat 5311, and the lifting plate 5313 is connected to the moving end of the lifting cylinder 5312; when the assembly jig 10 is detected, the detection sensor 532 transmits a signal to control the start of the lifting cylinder 5312. Specifically, when the assembly jig 10 reaches a predetermined position, the detection sensor 532 can detect and send a signal. The lifting plate 5313 is connected to the moving end of the lifting cylinder 5312. When the lifting cylinder 5312 is started, the lifting plate 5313 rises or falls accordingly, thereby realizing the lifting or lowering of the assembly jig 10. The detection sensor 532 is electrically connected to the lifting cylinder 5312 for controlling the start of the lifting cylinder 5312. The lifting cylinder 5312 is mounted on the fixed seat 5311, and its movable end is mechanically connected to the lifting plate 5313 to transmit the lifting action. The fixed seat 5311 is directly mounted on the first conveying mechanism 51 to provide support for the lifting component 531. The detection sensor 532 can accurately detect the position of the assembly fixture 10, ensuring that the lifting action is performed at the right time, thereby improving the assembly accuracy.

[0050] In this example, both the front-end assembly line 20 and the middle-end assembly line 30 are provided with a jig elevator 70, which is used to receive the assembly jig 10 conveyed by the second conveying mechanism 52 and convey it to the first conveying mechanism 51. Specifically, the jig elevator 70 first receives the assembly jig 10 conveyed by the second conveying mechanism 52, and prepares to transfer it to the first conveying mechanism 51. The jig elevator 70 adjusts the height of the jig through a lifting mechanism (such as a hydraulic or pneumatic system) to match the conveying surface of the first conveying mechanism 51. After the jig elevator 70 lifts the assembly jig 10 to an appropriate height, it moves it to the conveying surface of the first conveying mechanism 51 to ensure that the jig smoothly transitions to the next assembly stage. The safety risks of operators in the process of transferring jigs are reduced, and the safety of the production line is improved.

[0051] In this example, both the front-end assembly line 20 and the middle-end assembly line 30 include a baking feeding station 80, which receives the assembly jig 10 conveyed by the width-adjustable conveying device 50 and conveys the assembly jig 10 to the baking device 60. Specifically, the baking feeding station 80 first receives the assembly jig 10 conveyed by the width-adjustable conveying device 50 and prepares to transfer it to the baking device 60. The baking feeding station 80 ensures a smooth transition of the assembly jig 10 between different production stages, reducing delays or damage that may be caused by manual jig transfer.

[0052] In this example, the baking feeding station 80 includes a docking bracket 81, and a squaring mechanism 82 and a roller conveying mechanism 83 both arranged on the docking bracket 81; one end of the roller conveying mechanism 83 is docked with the width-adjustable conveying device 50, and the other end is docked with the baking device 60, and the conveying surface of the roller conveying mechanism 83 is inclined downward in the conveying direction; the squaring mechanism 82 is located above the roller conveying mechanism 83, and is used to squaring the assembly jig 10 located on the roller conveying mechanism 83. Specifically, the docking bracket 81 serves as the basic structure of the baking feeding station 80, and the docking bracket 81 supports the squaring mechanism 82 and the roller conveying mechanism 83 and ensures that they are properly docked. The roller conveying mechanism 83 is composed of a series of rollers, which are responsible for conveying the assembly jig 10 from the width-adjustable conveying device 50 to the baking device 60. The conveying surface of the roller conveying mechanism 83 is inclined downward, which helps to guide the assembly jig 10 to move smoothly, while reducing the risk of damage caused by friction or jamming. The alignment mechanism 82 ensures the correct position and orientation of the assembly jig 10 before entering the baking device 60, thereby improving the quality and consistency of the baking process.

[0053] In this example, the alignment mechanism 82 includes a transverse drive module 821, a vertical drive module 822 and an alignment plate 823; the transverse drive module 821 is arranged on the docking bracket 81; the vertical drive module 822 is installed at the moving end of the transverse drive module 821 and can be driven to move horizontally; the alignment plate 823 is installed at the lifting end of the vertical drive module 822 and can be driven to move in the vertical direction, and the bottom of the alignment plate 823 is arranged parallel to the conveying surface of the roller conveying mechanism 83. Specifically, the transverse drive module 821 is arranged on the docking bracket 81, and is responsible for driving the alignment plate 823 to move in the horizontal direction to adapt to the assembly jig 10 in different positions. The vertical drive module 822 is installed at the moving end of the transverse drive module 821 and can be driven to move horizontally. This module is responsible for moving the alignment plate 823 to the correct position after detecting the assembly jig 10. The alignment plate 823 is mounted on the lifting end of the vertical drive module 822 and can move in the vertical direction. The bottom of the alignment plate 823 is arranged parallel to the conveying surface of the roller conveying mechanism 83 to ensure that the alignment plate 823 can contact and align the assembly jig 10.

[0054] In this example, the horizontal reflux conveying device 42 includes two sets of parallel and spaced horizontal conveying mechanisms, the conveying surfaces of the two sets of horizontal conveying mechanisms are located on the same horizontal plane, and the conveying directions are opposite. Specifically, the design of the horizontal reflux conveying device 42 realizes the conveying of products in two directions, so that the products can be returned or diverted to different processing stations after testing.

Vibration can promote the movement of the jackets and ensure that they can enter the feeding guide rail 3112 continuously. The feeding guide rail 3112 is docked with the discharge port of the vibrating feeding assembly 3111 to form a channel for conveying the sheath from the vibrating feeding assembly 3111 to the sheath receiving mechanism 312. The design of the guide rail helps to guide and stabilize the conveying path of the sheath. The stop module 3113 is arranged at the discharge end of the feeding guide rail 3112 to control the discharge of the sheath. The stop module 3113 can be mechanically or electronically controlled, and can stop or release the sheath as needed to ensure that the sheath enters the sheath receiving mechanism 312 according to a predetermined rhythm. The discharge port of the vibrating feeding assembly 3111 is directly docked with the feeding guide rail 3112 to ensure that the sheath can be smoothly conveyed from the material tray to the guide rail. The discharge end of the feeding guide rail 3112 is arranged close to the sheath receiving mechanism 312 so that the sheath can directly enter the receiving mechanism. The material stopping module 3113 is installed at the discharge end of the feeding guide rail 3112, and cooperates with the sheath receiving mechanism 312 to control the discharge time and quantity of the sheath.
