Those skilled in the art can certainly combine the embodiments of the present application without creative labor to obtain other embodiments, and these embodiments are also within the protection scope of the present application.

[0021] The inventors of this application have discovered that the traditional power box lid sealing process mainly relies on manual operation. Operators need to hold a screwdriver and individually screw screws into the threaded holes of the power box body and lid to seal the lid and body. In practice, this method is inefficient and slow due to its complete reliance on manual operation. Furthermore, operators need to concentrate on tightening each screw, ensuring the accuracy of the tightening force and position. The work speed is limited by the operator's skill level, physical strength, and concentration, making it difficult to meet the demands of large-scale, high-efficiency production. This inefficient sealing method not only increases production costs but may also extend the production cycle, failing to meet the large market demand for power boxes in a timely manner. Therefore, this application discloses a power box lid sealing device and its application method, mainly employing the following solution: This application discloses a cover packaging device for a power supply box. (Refer to...) Figure 1 The device includes a frame 1, a conveying mechanism 2, a moving frame 11, a lifting frame 12, a clamping assembly 3, a screw conveying module 4, a mounting frame 13, and a drive assembly 5. The frame 1 serves as the supporting foundation for the entire device. The conveying mechanism 2 is responsible for conveying the power box and its cover to the designated position. The moving frame 11 slides horizontally on the frame 1. The lifting frame 12 moves vertically. The clamping assembly 3 is mounted on the lifting frame 12 to clamp screws. The screw conveying module 4 is used to convey screws to the clamping assembly 3. The mounting frame 13 slides vertically on the lifting frame 12. The drive assembly 5 drives the mounting frame 13 to slide vertically.

[0022] Reference Figure 2Multiple sets of conveying mechanisms 2 can be set to improve processing efficiency. Specifically, the conveying mechanism 2 includes a conveyor frame 21, a linear motor 22, and a mold box 23. The conveyor frame 21 is slidably mounted on the machine frame 1 in a horizontal direction, and the sliding direction of the conveyor frame 21 is perpendicular to the sliding direction of the moving frame 11. The linear motor 22 is mounted on the machine frame 1 to drive the conveyor frame 21 to move, providing stable and accurate linear motion. Multiple limit blocks 211 are also fixedly set on the conveyor frame 21, and the limit blocks 211 together form a placement area for placing the mold box 23. The mold box 23 is placed within the placement area formed by the limit blocks 211. The conveyor frame 21 is generally made of metal, which has good strength and stability. Its shape is a frame structure, which facilitates the installation of other components. The linear motor 22 can be a permanent magnet linear synchronous motor, etc., which has the characteristics of fast response speed and high precision. The mold box 23 can be customized according to the shape and size of the power box, and its interior is provided with a groove adapted to the power box to ensure the stability of the power box. The limiting block 211 ensures that the mold box 23 is placed in an accurate position and prevents it from shifting during the conveying process. The limiting block 211 can be a metal block or a plastic block, and its shape can be square, round, etc. It is fixed to the conveyor frame 21 by bolts or other means.

[0023] Reference Figure 2 Multiple rotary lifting cylinders 212 are fixedly installed on the conveyor frame 21. Each rotary lifting cylinder 212 has a pressure plate 213 fixedly installed at its output end. The pressure plate 213 is used to press the cover tightly against the power supply box. The rotary lifting cylinder 212 can realize the rotation and lifting action of the pressure plate 213, allowing the cover to accurately and tightly fit against the power supply box. The rotary lifting cylinder 212 can be a thin rotary cylinder, etc., characterized by its small size and flexible operation. The pressure plate 213 is generally made of rubber or other materials with a smooth surface to avoid damage to the cover and power supply box.

[0024] Reference Figure 3 The movable frame 11 is generally welded from metal profiles, which has good rigidity and strength. The frame 1 is provided with a first driving member 14 for driving the movable frame 11 to slide. Specifically, the first driving member 14 can be a cylinder, an electric push rod, a linear motor 22, etc., to provide a horizontal driving force, so as to drive the movable frame 11 to slide horizontally on the frame 1.

[0025] Reference Figure 3 The lifting frame 12 is also welded from metal profiles, giving it good rigidity and strength. The movable frame 11 is equipped with a second driving component 15 for driving the lifting frame 12 to move up and down vertically. Specifically, the second driving component 15 can be a cylinder, an electric push rod, a linear motor 22, etc., to provide vertical driving force, causing the lifting frame 12 to slide vertically on the movable frame 11.

[0026] Reference Figure 3 A guide rail 121 is fixedly mounted on the lifting frame 12. The length direction of the guide rail 121 is vertical, and the mounting frame 13 is slidably mounted on the guide rail 121. The drive assembly 5 includes a transmission screw 51 and a servo motor 52. The transmission screw 51 is rotatably mounted on the lifting frame 12, and the length direction of the transmission screw 51 is parallel to the length direction of the guide rail 121. The transmission screw 51 is threadedly engaged with the mounting frame 13. The servo motor 52 is fixedly mounted on the lifting frame 12, and the output shaft of the servo motor 52 is coaxially and fixedly connected to the transmission screw 51. When the servo motor 52 rotates, it drives the transmission screw 51 to rotate, thereby causing the mounting frame 13 to slide in the vertical direction. The transmission screw 51 can be a trapezoidal screw or a ball screw, which has high transmission efficiency and precision. The servo motor 52 can be selected with different power and speed as needed to meet the motion requirements of the mounting frame 13.

[0027] Reference Figure 3 and Figure 4 The clamping assembly 3 includes a mounting base 31, a first clamping block 32, a second clamping block 33, and an elastic element. The mounting base 31 is fixed to the lifting frame 12 by bolts. The first clamping block 32 and the second clamping block 33 are both rotatably mounted on the mounting base 31, and the first clamping block 32 and the second clamping block 33 deflect in a direction that approaches or moves away from each other. The elastic element is used to drive the first clamping block 32 and the second clamping block 33 to deflect in a direction that approaches each other. Specifically, the elastic element includes a compression spring 34. Two compression springs 34 are provided, and they correspond one-to-one with the first clamping block 32 and the second clamping block 33, respectively, for deflecting the first clamping block 32 and the second clamping block 33 in a direction that approaches each other. An installation section 35 for placing screws is provided between the first clamping block 32 and the second clamping block 33. The sidewall of the installation section 35 is inclined and adapted to the screw to be installed. The transmission rod 6 and the screwdriver head 61 rotatably pass through the mounting base 31 and are located between the first clamping block 32 and the second clamping block 33. The screw is conveyed to the mounting interval 35 between the first clamping block 32 and the second clamping block 33 by the screw conveying module 4. The mounting interval 35 initially limits the screw. Then, the mounting bracket 13 drives the transmission rod 6 to descend vertically. The motor 131 drives the transmission rod 6 to rotate, so that the screwdriver head 61 aligns with the screw, thereby screwing the screw into the threaded hole on the cover and the power box, fixing the cover and the power box. During the tightening process, the pressure of the screw, combined with the inclined side wall of the mounting interval 35, causes the first clamping block 32 and the second clamping block 33 to open slowly, while always maintaining an elastic clamping force on the screw, positioning the screw and ensuring that the screw is accurately screwed into the threaded hole on the cover and the power box, improving the packaging efficiency and quality.

[0028] Reference Figure 1 , 5The screw conveying module 4 includes a pneumatic screw feeder 41 and a screw conduit 42 connected to the pneumatic screw feeder 41. A feeding channel 311 is provided on the mounting base 31, which is connected to the installation section 35 between the first clamping block 32 and the second clamping block 33. The screw conduit 42 is connected to the feeding channel 311. The pneumatic screw feeder 41 can use air pressure to quickly and accurately convey screws through the screw conduit 42 to the installation section 35. The screw conduit 42 is generally made of transparent plastic tubing, which has good wear resistance and corrosion resistance.

[0029] Reference Figure 3 and Figure 5 A transmission rod 6 is vertically rotatably mounted on the mounting bracket 13. A motor 131 is mounted on the mounting bracket 13 to drive the transmission rod 6 to rotate. A screwdriver head 61 is provided at the end of the transmission rod 6. This combination enables the equipment to automatically complete the sealing work of the power box cover, improving the sealing efficiency and accuracy. The transmission rod 6 is generally made of metal shaft with a surface treated to reduce friction and wear. The motor 131 can be an AC motor 131 or a DC motor 131, with stable speed and large torque. The shape and size of the screwdriver head 61 are selected according to the type of screw, such as a Phillips screwdriver head 61 or a flathead screwdriver head 61.

[0030] Reference Figure 5 A buffer sleeve 62 is slidably fitted onto the end of the transmission rod 6 along its length. A screwdriver head 61 is fixedly mounted on the end of the buffer sleeve 62. An elastic element 63 is provided on the transmission rod 6 to drive the buffer sleeve 62 to move away from the transmission rod 6. A stud 611 is fixedly mounted on the end of the screwdriver head 61. An internal thread adapted to the stud 611 is provided inside the buffer sleeve 62. The screwdriver head 61 is threadedly connected to the buffer sleeve 62 through the stud 611. The elastic element 63 is a spring, which is located inside the buffer sleeve 62, and its two ends abut against the transmission rod 6 and the stud 611, respectively. The buffer sleeve 62 and the elastic element 63 can buffer the screw during the screwdriver head 61 docking with the screw and screwing in, so as to avoid the screw stripping due to the mismatch between the descending speed of the mounting bracket 13 and the thread on the screw during the tightening process; or due to the inaccurate alignment of the screw with the threaded hole on the cover, the screw and the cover will have a rigid collision, causing damage to the surface of the cover and affecting the quality of the finished product.

[0031] The implementation principle of a power box cover packaging device according to an embodiment of this application is as follows: This power box cover packaging device automates the power box cover packaging process through the coordinated operation of various mechanisms. The conveying mechanism 2 transports the power box and cover to the packaging station. The screw conveying module 4 transports screws to the clamping assembly 3. With the movement of the moving frame 11 and the lifting frame 12, the screws on the clamping assembly 3 are accurately aligned with the threaded connection holes on the cover. The motor 131 drives the transmission rod 6 to rotate, and with the descent of the mounting frame 13, the screwdriver head 61 engages with the screw, allowing the screw to be screwed into the threaded holes of the cover and the power box. Compared to traditional manual packaging methods, this improves packaging efficiency and quality, reduces production costs, reduces reliance on operators, and meets the needs of large-scale production.

[0032] This application also discloses an application method for a power supply box cover packaging device, including the following steps: S1. Place the power supply box inside the mold box 23, and place the box cover on top of the power supply box, ensuring accurate alignment of the threaded holes on the box cover with those on the power supply box. Activate the rotary lifting cylinder 212 to press the box cover firmly onto the power supply box using the pressure plate 213. In this step, the operator needs to accurately place the power supply box into the mold box 23, ensuring its stable position. Then, place the box cover on top of the power supply box, carefully aligning the threaded holes. Activate the rotary lifting cylinder 212 to lower and rotate the pressure plate 213, firmly pressing the box cover onto the power supply box, preparing for subsequent packaging work.

[0033] S2. Start the linear motor 22 to transport the mold box 23 to the packaging station via the conveyor frame 21. After the linear motor 22 starts, it drives the conveyor frame 21 to move horizontally, transporting the mold box 23 containing the power supply box and the lid to the designated packaging station. During the transport process, ensure that the movement of the conveyor frame 21 is smooth to prevent the mold box 23 from shaking and causing the power supply box and lid to shift.

[0034] S3. The screws are conveyed to the clamping assembly 3 via the screw conveying module 4. The pneumatic screw feeder 41 in the screw conveying module 4 conveys the screws through the screw pipe 42 to the feeding channel 311 of the mounting base 31, and then into the mounting interval 35 between the first clamping block 32 and the second clamping block 33.

[0035] S4. The first drive unit 14 moves the moving frame 11 horizontally above the power supply box, and the second drive unit 15 drives the lifting frame 12 to descend, so that the screws on the clamping assembly 3 are accurately aligned with the threaded connection holes on the pressure cap. This step requires precise control of the moving distance and position of the conveyor frame 21, the moving frame 11, and the lifting frame 12 to ensure that the subsequent screw installation is accurate.

[0036] S5. The mounting bracket 13 is driven to descend vertically, coordinating with the motor 131 to rotate the transmission rod 6, causing the screwdriver head 61 to engage with the screw. As the mounting bracket 13 continues to descend, the screwdriver head 61 screws the screw into the threaded holes on the cover and power supply box, securing the cover and power supply box. This step requires precise control of the rotation speed of the transmission rod 6 and the moving speed of the mounting bracket 13 to ensure that the screw can be stably screwed into the corresponding threaded holes on the power supply box and cover.

[0037] S6. Next, repeat steps S2-S5 until all screws are connected to the threaded holes on the cover and power supply box, thus achieving automated encapsulation of the cover on the power supply box. Based on the number and position of the threaded holes on the power supply box and cover, continuously adjust the positions of the conveyor frame 21 and the moving frame 11, repeating the above steps until all screws are installed in all threaded holes, completing the entire encapsulation process.

[0038] S7. After packaging is completed, the packaged power supply box is sent out using the conveyor 21. After packaging is completed, the conveyor 21 transports the packaged power supply box to the designated discharge position for subsequent processing.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

S5: The drive assembly (5) drives the mounting bracket (13) to descend vertically, and the motor (131) drives the transmission rod (6) to rotate, so that the screwdriver head (61) and the screw are connected. As the mounting bracket (13) continues to descend, the screwdriver head (61) screws into the threaded holes on the cover and the power box, and fixes the cover and the power box. S6: Then, repeat steps S2-S5 until all screws are connected to the threaded holes on the cover and the power box, thus achieving automated encapsulation of the cover on the power box. S7: After the packaging is completed, the packaged power box is sent out using the conveyor (21).
