Description

Technical Field

[0001] This invention relates to the field of motor packaging technology, and more specifically to an automated motor packaging production line. Background Technology

[0002] Electric motors, as a type of electric drive device, are widely used in various fields. For most motors, packaging is required after production. Traditional manual packaging methods are inefficient, have inconsistent quality, and are labor-intensive, so they are gradually being replaced by automated packaging production lines.

[0003] Currently, there are two main types of automated packaging production lines for small and medium-sized motors on the market: semi-automatic packaging lines and fully automatic packaging lines. In the semi-automatic packaging line, the motor is transported to the packaging station via a conveyor belt. Then, manual labor places cushioning pads into the packaging box, seals the motor with film, and places it in the box. Finally, the box is sealed with tape. While this method improves efficiency to some extent compared to manual packaging, some processes still involve manual processes, resulting in overall low packaging efficiency.

[0004] A fully automated packaging production line mainly includes equipment such as motor conveyor belts, packaging robots, box conveyor belts, box sealing machines, and labeling machines. The motor conveyor belt transports the motors from the production line to the packaging station. The packaging robot is responsible for gripping the motors into the packaging boxes and precisely positioning and placing them. The box conveyor belt transports the packaging boxes containing the motors to the next station. The box sealing machine automatically seals the packaging boxes, and the labeling machine affixes labels to the boxes, identifying relevant motor information such as brand, model, and batch number. Due to its high degree of automation, this production line can achieve efficient and continuous packaging operations, reducing manual intervention and improving production efficiency. Simultaneously, it can achieve precise motor positioning and placement, reducing damage to packaging boxes and motor displacement, improving packaging quality. Furthermore, the reduced manual intervention also lowers the probability of production accidents, improving production safety.

[0005] However, existing fully automated packaging lines transport motors and packaging boxes from the preceding workstation to the packaging workstation via conveyor belts. Once at the packaging workstation, a robotic arm or vacuum suction cup removes the motor from the conveyor belt and places it into the packaging box. The packaging box containing the motor is then placed back onto the conveyor belt, where an automatic box-sealing machine seals it with tape. Finally, the packaged motor is sent to the next workstation or transport area. In this process, the motor needs to go through at least six steps: transport, gripping, placing, returning, sealing, and transporting out to complete the packaging. Furthermore, the gripping, placing, and returning steps require positioning operations, which consume additional time and result in low packaging efficiency.

[0006] Therefore, there is an urgent need for a high-performance, highly applicable, and automated motor-driven automatic packaging production line to overcome the above problems. Summary of the Invention

[0007] The technical problem to be solved by the present invention is that the existing motor packaging production line requires multiple packaging processes and repeated positioning during the process, resulting in low efficiency in packaging motors.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This invention provides an automatic motor packaging production line, comprising an input unit, a combination unit, a clamping mechanism, an auxiliary input unit, a packaging unit, an output unit, and a control component. The input unit is used to input the motor to be packaged and the buffer required for packaging the motor. A combination unit is provided at the end of the input unit, which is used to align the motor and install the buffer onto the motor. A clamping mechanism is provided below the combination unit, which is used to clamp the box plate and place the box plate supporting the motor stably onto the packaging unit. Auxiliary input units are provided on both sides of the clamping mechanism, which are used to input the box plate required for packaging the motor. A packaging unit is fixedly installed at the center of the clamping mechanism, which is used to package the box plate into a motor packaging box and package the motor with the buffer installed into the motor packaging box. An output unit is provided below the packaging unit, which is used to deliver the packaged motor and affix a label to the packaging box. The input unit, combination unit, clamping mechanism, auxiliary input unit, packaging unit, and output unit are all electrically connected to the control component.

[0010] The input unit includes a motor input unit, an upper buffer component conveying mechanism, and a lower buffer component conveying mechanism. The motor input unit is located on one side of the assembly unit and is used to transport the finished motor from the assembly station to the assembly unit. The upper buffer component conveying mechanism is fixedly installed above the assembly unit, and the lower buffer component conveying mechanism is fixedly installed on the other side of the assembly unit. The upper and lower buffer component conveying mechanisms are used to convey the upper and lower buffer components to the assembly unit, respectively.

[0011] Furthermore, the motor input unit includes a motor transmission belt, reduction rollers, and limiting plates. The motor transmission belt is fixed on a plane and is used to transport the finished motor from the installation station to the packaging station. The end of the motor transmission belt is equipped with reduction rollers, which are used to reduce the speed of the motor leaving the motor transmission belt, so that the motor can leave the motor conveying unit smoothly and reduce the initial kinetic energy of the motor when entering the assembly unit. Limiting plates are symmetrically arranged on both sides of the motor transmission belt and the reduction rollers. The front end of the limiting plates is bent outward at a certain angle to facilitate the entry of misaligned motors into the channel constrained by the limiting plates, so as to initially limit the motors.

[0012] Both the upper and lower buffer conveyor mechanisms are rectangular structures, with buffer conveyor push rods at their bottom ends. These push rods are electrically connected to the control assembly. The upper buffer conveyor mechanism is fixedly installed diagonally above the assembly unit to provide the upper buffer for packaging the motor. The lower buffer conveyor mechanism is fixedly installed on one side of the assembly unit to provide the lower buffer for packaging the motor. Both mechanisms are rectangular, and the upper and lower buffers to be installed are vertically stored inside from top to bottom. The upper buffer component conveying mechanism has an upper buffer component output port at its bottom for outputting the upper buffer component to the assembly unit. A buffer component conveying push rod is provided behind the upper buffer component output port for pushing the bottommost upper buffer component from the upper buffer component conveying mechanism into the assembly unit. The lower buffer component conveying mechanism has a lower buffer component output port at its bottom for outputting the lower buffer component to the assembly unit. A buffer component conveying push rod is also provided behind the lower buffer component output port for pushing the bottommost lower buffer component from the lower buffer component conveying mechanism into the assembly unit.

[0013] The assembly unit includes an assembly positioning frame, alignment elements, buffer mounting push rods, and support components. The assembly positioning frame is rectangular, with a buffer mounting push rod positioned directly above it. This push rod is used to push the upper buffer onto the motor. The assembly positioning frame has a motor input port at its connection to the motor conveying unit, and upper and lower buffer input ports at its connection to the buffer conveying unit. The upper buffer input port is located above the motor input port. Alignment elements are slidably mounted on the four corners of the assembly positioning frame. These alignment elements include four retractable alignment rods that can extend and retract horizontally along the assembly positioning frame. Positioning blocks, each with a rounded corner facing the center, are used to align the motor so that the upper and lower buffer components can be installed on the motor later. The top of the positioning element is flush with the bottom of the motor input port. Below the positioning element is a hollow structure for placing the lower buffer component. A support assembly is set at the bottom of the assembly unit. A pressure sensor is installed in the support assembly and is electrically connected to the buffer component mounting push rod. When the motor is completely placed on the support assembly, the pressure sensor transmits an electrical signal to the buffer component mounting push rod, causing the push rod to press down on the upper buffer component, so that the upper buffer component is installed on the motor.

[0014] It should be noted that, since motors come in various shapes, when the motor packaging surface is not a regular shape such as square or round, the positioning block can also be made into an angled shape. Compared with rounded corners, since the slope of the angled corner is the same at every point, it is more adaptable and can better adapt to the positioning of motors with irregular shapes, thus making it easier to install buffers and pack them.

[0015] Furthermore, the support assembly includes four openable support plates and is electrically connected to the control assembly. After the motor completes the installation of the buffer, the support plates can open and close in all directions under the action of the control assembly, so that the motor leaves the assembly unit and returns to the closed state after the motor leaves the assembly unit.

[0016] The clamping mechanism includes slide rails, electric sliders, rotating rods, support rods, adjusting plates, and electrically controlled clamps. Four slide rails are fixedly installed around the packaging unit. Each slide rail has an electric slider slidably connected to it. During the packaging process, the electric slider drives the components mounted on it to move towards the center along the slide rail. When the packaging is complete, it returns to its initial position along the same path. A rotating rod is rotatably mounted on the left-side electric slider. After completing one packaging cycle, the rotating rod rotates 180°, allowing for the exchange of positions on both sides. Identical adjusting plates are rotatably connected to both ends of the rotating rod, and each adjusting plate is fixedly connected to an electrically controlled clamp. The electrically controlled clamp near the packaging unit is used to grip one side panel of the semi-finished box panel during the packaging process. The electrically controlled clamp on the other side is used to prepare for gripping the semi-finished box panel required for the next packaging from the auxiliary input unit. Support rods are fixedly installed on the electric sliders on the other three sides (excluding the left side). Adjustment plates are rotatably connected to the ends of the support rods. Electrically controlled clamps are fixedly installed on the adjustment plates. The electrically controlled clamps on these three sides, together with the electrically controlled clamp on the left side, are used to grip one side panel of the semi-finished box panel during the motor packaging process, so that all four sides of the semi-finished box panel are subjected to the same support force, maintaining the safety and stability of the packaging process.

[0017] After the motor leaves the assembly unit, the clamping mechanism picks up the motor with the buffer installed on it by holding the semi-finished box plate with electric grippers. Under the action of the control component, the electric sliders around the perimeter move towards the center along the slide rail, causing the side plates of the semi-finished box plate to bend from the horizontal to the vertical direction. At the same time, the bottom plate of the semi-finished box plate and the motor placed on the bottom plate move downward until the semi-finished box plate and the motor placed on it smoothly reach the packaging unit.

[0018] In addition, the right-side adjustment plate is equipped with electrically controlled clamps in two directions, with an included angle of 90° between the two directions. The electrically controlled clamp in the horizontal direction is used to clamp the right side plate of the semi-finished box when the electrically controlled clamp on the left side of the clamping mechanism is clamped from the auxiliary input unit to the center of the clamping mechanism. The electrically controlled clamp in the vertical direction is used to clamp the top plate from the auxiliary input unit. Both the electrically controlled clamps in the horizontal and vertical directions are fixedly connected to the adjustment plate to maintain synchronous rotation. When the electrically controlled clamp in the horizontal direction rotates 90° during the packaging process, the electrically controlled clamp in the vertical direction also rotates 90° to achieve the effect of bringing the top plate into the packaging unit.

[0019] The auxiliary input unit includes a box panel conveyor belt and a box cover conveyor belt. The box panel conveyor belt is located on the left side of the clamping mechanism and is used to transport the semi-finished box panels required for packaging motors to the left side of the clamping mechanism. The box cover conveyor belt is located on the right side of the clamping mechanism and is used to transport the top plate required for packaging motors to the right side of the clamping mechanism. Since the width of the semi-finished box panels is greater than the width of the top plate, the width of the box panel conveyor belt is greater than the width of the box cover conveyor belt.

[0020] The packaging unit includes a packaging limiting frame, a lifting plate, and a nailing mechanism. The packaging limiting frame has a rectangular structure with a ramp at the motor inlet at its upper end. The ramp is used to allow the side panels of the semi-finished box to rotate continuously and stably from a horizontal to a vertical position when the clamping mechanism moves the semi-finished box panel from all sides towards the center. Below the ramp is a vertical rectangular groove, which is used to limit the packaging box that has entered the groove and facilitate nailing. A lifting plate is slidably installed inside the vertical rectangular groove. The lifting plate can slide along the vertical rectangular groove and is used to send the motor and packaging box panel that have entered the vertical rectangular groove out of the packaging unit and provide support for them during the process. Multiple through holes are opened on the side wall of the vertical rectangular groove, and a nailing mechanism is fixedly installed in the through holes. The nailing mechanism is used to nail the packaged box.

[0021] It is worth noting that, in order to ensure that the fixing nails can accurately seal the motor packaging box, the plane where the central axis of the through hole is located should coincide with the plane where the side plate of the box enters the vertical rectangular groove. That is, the installation position of the nailing mechanism should correspond to the position of the two side plates.

[0022] Furthermore, the lifting plate is provided with two pieces. A hinge is provided on one side of the lifting plate. The hinge connects the lifting plate and the packaging limit frame. The lifting plate is electrically connected to the control component. When the lifting plate slides along the vertical rectangular groove to the bottom, the lifting plate opens and closes from the middle, allowing the packaged motor to leave the packaging unit. Under the action of the control component, the lifting plate that releases the motor returns to its original position and rises again to the top of the vertical rectangular groove, completing the bidirectional stroke cycle.

[0023] The output unit includes an output conveyor belt and a labeling mechanism. The starting point of the output conveyor belt is located directly below the packing mechanism. The output conveyor belt is used to send the packaged motor out of the packaging station. Since the packaged motor still needs to be labeled, a labeling mechanism is set on the path of the output conveyor belt. The labeling mechanism is located directly above the output conveyor belt and is equipped with a signal plate. When the motor packaging box passes the labeling mechanism, the signal plate drives the rotating shaft to rotate, and the labeling machine at the top receives the signal to realize automatic labeling.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The present invention discloses an automatic motor packaging production line. By vertically fixing the upper and lower buffer conveyor mechanisms on the assembly unit, the transportation time of the buffer components is saved, and the buffer components can be in place before the motor arrives, saving packaging time. The motor packaging process is locked within the time and space between the motor descending from the motor conveyor belt to the output conveyor belt. This reduces the motor packaging process from at least 6 steps (transportation, gripping, placement, return, sealing, and dispatch) in traditional automatic motor packaging production lines to only 4 steps (transportation, positioning, descent, and dispatch). Traditional robotic arms still require time for positioning operations during gripping, placement, and return, resulting in low efficiency for each individual step. In contrast, the present invention achieves initial positioning on the motor conveyor belt using limit plates, consuming virtually no additional time. Furthermore, positioning in the assembly unit using aligning elements is combined with the motor's descent process, minimizing time consumption. The present invention improves efficiency in transportation, positioning, and packaging, thereby increasing overall packaging efficiency.

[0026] 2. The present invention provides an automatic motor packaging production line. By setting a packaging mechanism below the assembly unit and fixing clamping mechanisms around the packaging mechanism, the packaging box can be prepared in place before the motor enters the packaging mechanism. When the motor with the buffer installed descends onto the prepared packaging box, the clamping mechanisms converge towards the center, so that the box panels around the motor are attached to the motor. Then, the box panels are fixed by a nailing mechanism, thereby realizing automatic packaging of the motor. This avoids the problems caused by the traditional method of manually or by using a robotic arm to transfer the motor into the packaging box. At the same time, the motor is absolutely safe and reliable during the packaging process, achieving a stable packaging effect.

[0027] 3. The automatic motor packaging production line of the present invention enables automatic position correction of motors of different sizes and specifications by setting a positioning element in the combination unit. A lower buffer pad for pre-packaging the motor is preset below it, so that the motor can be directly installed on the lower buffer pad by its own weight, without the need for the use of a robot or manual placement of the buffer into the packaging box as in the traditional packaging method. In this way, the present invention realizes automatic packaging of motors of different sizes or types. Attached Figure Description

[0044] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0045] Example 1: As Figures 1 to 3 As shown, the present invention provides an automatic motor packaging production line, comprising an input unit 1, a combination unit 2, a clamping mechanism 3, an auxiliary input unit 4, a packaging unit 5, an output unit 6, and a control component 7. The input unit 1 is used to input the motor to be packaged and the buffer required for packaging the motor. The combination unit 2 is located at the end of the input unit 1. The combination unit 2 is used to align the motor and install the buffer onto the motor. The clamping mechanism 3 is located below the combination unit 2. The clamping mechanism 3 is used to clamp the box plate and smoothly place the box plate supporting the motor onto the packaging unit 5. The auxiliary input unit 4 is provided on both sides of the clamping mechanism 3. The auxiliary input unit 4 is used to input the box plate required for packaging the motor. The packaging unit 5 is fixedly installed in the center of the clamping mechanism 3. The packaging unit 5 is used to package the box plate into a motor packaging box and package the motor with the buffer installed into the motor packaging box. The output unit 6 is provided below the packaging unit 5. The output unit 6 is used to send out the packaged motor and affix a label to the packaging box. The input unit 1, the combination unit 2, the clamping mechanism 3, the auxiliary input unit 4, the packaging unit 5 and the output unit 6 are all electrically connected to the control component 7.

[0046] When the motor is packaged, the input unit 1 first transports the motor to be packaged and the cushioning components required for packaging the motor to the assembly unit 2. In the assembly unit 2, the motor is positioned and the cushioning components are installed. The motor with the cushioning components installed then leaves the assembly unit 2 and reaches the semi-finished box plate held by the clamping mechanism 3. Subsequently, the clamping mechanism 3 moves towards the center, causing the side panels of the semi-finished box plate to bend. At the same time, the motor begins to fall along with the bottom plate of the semi-finished box plate. When it falls to the packaging unit 5, the packaging unit 5 continues to descend with the box plate containing the motor. When the semi-finished box plate is attached to the motor until a three-dimensional packaging box is formed, the packaging unit 5 reinforces it with nails. The packaged motor falls to the output unit 6, where the labeling operation is performed, thus completing the entire packaging process.

[0047] Existing technologies for motor packaging mostly rely on manual labor or robotic arms to place the motor and cushioning components into the packaging box. This method is not only inefficient and costly in terms of labor, but also prone to damage when the motor is heavy due to insufficient gripping. Compared with traditional motor packaging methods, this invention, through the combination unit 2, allows the cushioning components to be installed on the motor simultaneously with its positioning, saving time on cushioning component installation. Furthermore, the clamping mechanism 3 and the packaging unit 5 bring the semi-finished box panel closer to the motor, eliminating the need for handling the motor during packaging and reducing the risk of accidental damage. Moreover, because this invention employs a fully automated packaging method under the control component 7, it improves work efficiency and ensures a stable and controllable packaging process.

[0048] like Figure 4 and Figure 7As shown, the input unit 1 includes a motor input unit 11, an upper buffer conveying mechanism 12, and a lower buffer conveying mechanism 13. The motor input unit 11 is located on one side of the combined unit 2. The upper buffer conveying mechanism 12 is fixedly installed diagonally above the combined unit 2, and the lower buffer conveying mechanism 13 is fixedly installed on the other side of the combined unit 2. The motor input unit 11 includes a motor transmission belt 111, a reduction roller 112, and a limiting plate 113. The motor transmission belt 111 is fixed on a plane and is used to transport finished motors from the installation station to the packaging station. The reduction roller 112 is provided at the end of the motor transmission belt 111. To enhance the deceleration effect, two reduction rollers 112 are provided. The limiting plate 113 is symmetrically arranged on both sides of the motor transmission belt 111 and the reduction roller 112. The front end of the limiting plate 113 is bent outward at a certain angle to facilitate the entry of misaligned motors into the channel constrained by the limiting plate 113. When the motor is transported on the motor conveyor belt 111, it enters the space constrained by the limiting plate 113 through the bent part set at the front end of the limiting plate 113, so that the originally uneven motors are arranged into a straight line, realizing the initial limiting of the motor. Since the motor has gained kinetic energy on the motor conveyor belt 111, the motor can decelerate when passing the deceleration roller 112 at the end, so that the motor can leave the motor input unit 11 smoothly and reduce the initial kinetic energy of the motor when entering the next station.

[0049] like Figure 1 and Figure 7As shown, both the upper buffer conveying mechanism 12 and the lower buffer conveying mechanism 13 are rectangular structures, and both have a buffer conveying push rod 121 at their bottom ends. The buffer conveying push rod is electrically connected to the control component 7. The upper buffer conveying mechanism 12 is fixedly installed diagonally above the combined unit 2 to provide the combined unit 2 with an upper buffer for packaging the motor. The lower buffer conveying mechanism 13 is fixedly installed on one side of the combined unit 2 to provide the combined unit 2 with a lower buffer for packaging the motor. Both the upper buffer conveying mechanism 12 and the lower buffer conveying mechanism 13 are rectangular structures, and the upper and lower buffers to be installed are vertically stored inside them from top to bottom. The bottom end of the upper buffer conveying mechanism 12 has an opening for conveying the upper buffer... The punch is output to the upper buffer output port of the combined unit 2. The upper buffer output port is provided with a buffer conveying push rod 121. The upper buffer conveying mechanism 12 stores multiple upper buffers. When there are no upper buffers in the combined unit 2, the buffer conveying push rod will automatically push the bottom upper buffer into the combined unit 2. The bottom end of the lower buffer conveying mechanism 13 is provided with a lower buffer output port for outputting lower buffers to the combined unit 2. The buffer conveying push rod 121 is also provided behind the lower buffer output port. When there are no lower buffers in the combined unit 2, the buffer conveying push rod 121 will automatically push the bottom lower buffer from the lower buffer conveying mechanism 13 into the combined unit 2.

[0050] like Figures 5 to 7As shown, the assembly unit 2 includes an assembly positioning frame 21, a positioning element 22, a buffer mounting push rod 23, and a support assembly 24. The assembly positioning frame 21 has a rectangular structure. It has a motor input port 211 at its connection with the motor input unit 11, and an upper buffer input port 212 and a lower buffer input port 213 at its connections with the upper buffer input mechanism 12 and the lower buffer input mechanism 13, respectively. The buffer mounting push rod 23 is positioned directly above the assembly positioning frame 21, and the positioning element 22 is slidably mounted on the four corners of the assembly positioning frame 21. The positioning element 22 includes four positioning blocks 221 that can extend and retract along the assembly positioning frame 21. Each positioning block 221 has a rounded corner facing the center. The top of the positioning element 22 is flush with the bottom of the motor input port 211. The positioning element 22 can extend and retract in the horizontal direction. Below the positioning element 22 is a hollow structure for placing the lower buffer component. The bottom of the assembly positioning frame 21 is provided with the support assembly 24. The support assembly 24 is provided with a pressure sensor and is electrically connected to the buffer component mounting push rod 23. The support assembly 24 includes four openable support plates 241. After the motor enters the assembly unit 2, it pauses briefly above the positioning element 22, and then presses the positioning element 22 to the left and right under its own weight, enabling the motor to automatically correct its position. Once the motor has corrected its position, it falls onto the lower buffer directly below the positioning element 22, achieving automatic installation of the lower buffer and the motor. When the motor falls onto the lower buffer, the pressure sensor in the support assembly 24 below the lower buffer senses the pressure, causing the buffer installation push rod 23 to move downwards, installing the upper buffer onto the motor. Then, the support plate 241 opens and closes to send the motor with the buffer installed out of the assembly unit 2. Compared with the traditional robotic arm for installing buffers, this invention only requires a unique installation station structure and the setting of the buffer installation push rod 23 to achieve the installation of buffers, saving a large number of control units, reducing costs, and improving efficiency.

[0051] like Figures 8 to 11As shown, the clamping mechanism 3 includes a slide rail 31, an electric slider 32, a rotating rod 33, a support rod 34, an adjusting plate 35, and an electrically controlled clamp 36. Four slide rails 31 are provided, each fixedly installed around the packaging unit 5. An electric slider 32 is slidably connected to each slide rail 31. The rotating rod 33 is rotatably mounted on the left electric slider 32, with the adjusting plate 35 rotatably connected to both ends of the rotating rod 33. The electrically controlled clamp 36 is fixedly connected to the adjusting plate 35. Support rods 34 are fixedly mounted on the electric sliders 32 on the other three sides, with the adjusting plate 35 rotatably connected to the end of the support rod 34. The electrically controlled clamp 36 is fixedly mounted on the adjusting plate 35. The right-side adjusting plate 35 has electrically controlled clamps 36 arranged in two directions, with an included angle of 90° between the two directions. The horizontal electrically controlled clamps 36 and the vertical electrically controlled clamps 36 rotate synchronously. When the horizontal electrically controlled clamps 36 rotate 90° during packaging, the vertical electrically controlled clamps 36 also rotate 90°. When the motor enters the semi-finished box plate held by the clamping mechanism 3, the clamping mechanism 3 moves towards the center along the slide rails 31 fixedly installed around the perimeter via the electric slider 32. At the same time, the adjusting plate 35, along with the electrically controlled clamps 36 fixedly connected to it, rotates downward with the side plates of the semi-finished box plate. This allows the side plates of the semi-finished box plate to converge towards the motor during descent, saving packaging time. When the side plates of the semi-finished box plate are completely bent from a horizontal state to a vertical state, the clamping mechanism 3, originally positioned on the right side... The electrically controlled clamp 36, which is vertically positioned and holding the top plate, rotates exactly 90°. At this point, the top plate is directly above the motor. The electrically controlled clamp 36 releases, and the top plate falls onto the top of the packaging box, sealing the box. Then, the remaining electrically controlled clamps 36 release the side plates they are holding. The clamping mechanism 3 returns to its initial position via the electric slider 32 along the slide rail 31. Simultaneously, the rotating rod 33 on the left side of the clamping mechanism 3 rotates 180°, removing the next semi-finished box panel from the auxiliary input unit 4 to the packaging station.

[0052] like Figure 9 and Figure 10 As shown, the auxiliary input unit 4 includes a box panel conveyor belt 41 and a box cover conveyor belt 42. The box panel conveyor belt 41 is located on the left side of the clamping mechanism 3, and the box cover conveyor belt 42 is located on the right side of the clamping mechanism 3. The width of the box panel conveyor belt 41 is greater than the width of the box cover conveyor belt 42. During motor packaging, the box panel conveyor belt 41 is used to transport the semi-finished box panels required for packaging the motor to the left side of the clamping mechanism 3, while the box cover conveyor belt 42 is used to transport the top plate required for packaging the motor to the right side of the clamping mechanism 3.

[0053] like Figure 12 and Figure 13 As shown, the packaging unit 5 includes a packaging limiting frame 51, a lifting plate 52, and a nailing mechanism 53. The packaging limiting frame 51 has a rectangular structure with ramps 511 around the motor inlet at its upper end. When the motor is sealed, the side panels of the semi-finished box will bend from a horizontal to a vertical position. The ramps 511 make this process smoother. Below the ramps 511 is a vertical rectangular groove 512, and the lifting plate 52 is slidably installed inside the vertical rectangular groove 512. Two lifting plates 52 are provided. The side wall of the vertical rectangular groove 512 has multiple through holes, and the nailing mechanism 53 is fixedly installed in the through holes. When the motor descends to the vertical rectangular groove 512, the lifting plate 52 carries the motor with the box panel and moves downward along the vertical rectangular groove 512. Due to the constraint of the groove, the side panel of the wooden box is fixed. At this time, the nailing mechanism 53 nails it and fixes it. When it slides to the lowest point, the switch is triggered to open the middle of the two lifting plates 52, so that the packaged motor leaves the packaging unit 5.

[0054] like Figure 14 As shown, the output unit 6 includes an output conveyor belt 61 and a labeling mechanism 62. The starting point of the output conveyor belt 61 is located directly below the packing mechanism. Since the packaged motors still need to be labeled, the labeling mechanism 62 is arranged along the path of the output conveyor belt 61, and the labeling mechanism 62 is located directly above the output conveyor belt 61. The labeling mechanism 62 is equipped with a signal guard plate 621, which is located on the path that the packaging box will pass through. After the motor completes the sealing of the box, it enters the output conveyor belt 61. When the packaging box passes the signal guard plate 621, the signal guard plate 621 drives the rotating shaft to rotate, and the labeling machine at the top receives the signal and can automatically perform the labeling operation.

[0055] Example 2: Since motors vary in size and model in actual production, when it is necessary to package motors with irregular shapes, the centering block 221 of the centering element 22 in the combination unit 2 can be angled at one corner. Compared with the rounded corner of the centering block 221 in Example 1, since the slope of the angle is the same at every point, it is more adaptable and can better adapt to the positioning of motors with irregular shapes, so that buffers can be installed and the motors can be boxed and packaged.

[0056] Example 3: When the aspect ratio of the motor to be packaged is larger than that of a general motor, the angle between the upper slope 511 of the packaging limit frame 51 and the horizontal plane can be adjusted accordingly. A smaller angle means a gentler slope. During the process of the semi-finished wooden board carrying the motor descending from the packaging unit 5, the bending process of its side plate is also more stable, ensuring the safety and reliability of the motor packaging process.

[0057] In the operation of this invention, the motor to be packaged is first transported from the installation station to the assembly unit 2 via the motor conveyor belt 111. During the transportation process, the motor to be packaged is initially limited by the limiting plate 113. When the motor to be packaged enters the assembly unit 2 from the motor input unit 11, the positioning element 22 automatically corrects it so that it falls accurately onto the lower buffer piece preset below the positioning element 22. At the same time, the upper buffer piece preset above the assembly positioning frame 21 is installed onto the motor to be packaged by the buffer piece mounting push rod 23. Thus, the motor to be packaged is pre-packaged.

[0058] After pre-packaging is completed, the support component 24 installed below the assembly positioning frame 21 opens outwards, allowing the pre-packaging motor with the buffer installed to fall onto the bottom plate of the semi-finished box panel held by the clamping mechanism 3. Then, the clamping mechanism holds the four side panels of the semi-finished box panel and moves them towards the center, bending the four side panels. When the semi-finished wooden board carrying the pre-packaging motor lands on the packaging unit 5, the lifting plate 52 inside the packaging unit 5 moves downwards along the packaging limiting frame 51 with the semi-finished wooden board carrying the pre-packaging motor until all four side panels of the semi-finished box panel are bent 90°, thus transforming the semi-finished box panel into a three-dimensional packaging box. At this point, the clamping... The electrically controlled clamp on the right side of mechanism 3 also rotates 90°, and the top plate it holds falls directly above the three-dimensional packaging box, thus sealing the pre-packaged motor. At the same time, the electrically controlled clamp in clamping mechanism 3 releases the side plate in the semi-finished wooden board. As the lifting plate 52 continues to descend, the nailing mechanism 53 nails the three-dimensional packaging box in place. When the lifting plate 52 moves to the bottom of the packaging limiting frame 51, the middle of the lifting plate 52 opens, allowing the packaging box containing the motor to fall onto the output conveyor belt 61. The packaging box is labeled by the labeling mechanism 62 while being transported on the output conveyor belt 61. Thus, the packaging of the motor is completed.
