Description

Technical Field

[0001] This utility model relates to the field of product packing aids technology, specifically to a product packing aid device. Background Technology

[0002] In the production process of cylindrical batteries, the post-repair packaging stage is a crucial step in ensuring the safe transportation and storage of the products. Currently, the packaging method used for these cylindrical batteries, due to its three-layer stacking structure, results in a complex and challenging operation. Specifically, after the cylindrical batteries have been repaired, two workers first need to move them from the workbench to the product racks in the packaging area and secure them. Subsequently, when loading them into the second and third layers of packaging, due to height restrictions, four additional workers need to stand at the four corners of the cylindrical battery rack and work together to lift the approximately 50kg product along with the rack until the rack is aligned with the slide rail inside the packaging. At this point, two workers at the front of the rack hold the rack and push the entire rack along the slide rail into the packaging. Finally, the nuts are tightened and the box door is closed to complete the packaging.

[0003] This traditional packing method has the following two drawbacks in practical applications:

[0004] 1. From the inspection workbench to the final packaging of cylindrical battery products, the entire process requires at least six people working together. This large amount of manual labor not only causes labor costs to snowball, but the cumbersome and lengthy process also severely hinders the improvement of packaging efficiency.

[0005] 2. The cylindrical battery product, combined with its bracket, weighs 50kg. Furthermore, the packaging box has a three-layer structure, requiring the product and bracket to be lifted to a considerable height for packing. This poses a significant challenge to the physical strength of the operators. Such high-intensity labor not only easily leads to operator fatigue and increases the risk of safety accidents, but also negatively impacts packing quality, thereby affecting the overall delivery efficiency and quality of the cylindrical battery product.

[0006] To address the problems existing in current technologies, it is necessary to develop a product packing assistance device that can accurately match the height of three-layer stacked packaging boxes, completely eliminating the need for heavy manual lifting operations, reducing the labor intensity of operators, thereby breaking through the bottleneck of traditional packing methods and achieving efficient, safe, and low-cost operation in the packing process. Summary of the Invention

[0007] To address the shortcomings of the existing technology, this utility model provides a product packing auxiliary device. Its lower support frame is equipped with an adjustable component to flexibly adapt to packing boxes of different heights. An upper support plate, mounted on the adjustable component, stably supports the product tray, and the inclined face facilitates smooth connection with the slide rail. A controller and drive component work together to precisely control the lifting and lowering of the support plate. Bottom casters facilitate device movement, comprehensively improving packing efficiency and reducing labor costs and intensity.

[0008] Specifically, this utility model provides a product packing auxiliary device, including: a lower support frame, wherein the lower support frame is equipped with an adjustment component for adjusting the height of the packing auxiliary device; an upper support plate is installed on the adjustment component for placing product trays; the upper support plate is provided with an inclined face interface to facilitate docking between the support plate and the packaging tray slide rail; the lower support frame is equipped with a controller and a drive component, wherein the controller and drive component cooperate to regulate the lifting stroke and speed of the upper support plate to achieve precise control of height adjustment; and casters are installed at the bottom of the lower support frame for realizing the overall position movement of the packing auxiliary device.

[0009] Furthermore, the adjusting components include a lifting frame, a connecting rod, a lower guide wheel connecting rod, a sliding screw, a guide wheel, a guide groove, and an upper guide wheel connecting rod;

[0010] The lifting frame is designed as a scissor structure, with one end connected to the upper support plate and the other end connected to the lower support frame.

[0011] Guide grooves are respectively set above the lower support frame and below the upper support plate; there are two sets of guide wheels, which are respectively installed above the lifting frame and below the lifting frame. The guide wheel above the lifting frame is slidably connected to the guide groove below the upper support plate, and the guide wheel below the lifting frame is slidably connected to the guide groove above the lower support frame; the sliding cooperation between the guide wheels and the guide grooves provides guidance for the lifting of the lifting frame.

[0012] The sliding screw is installed on the lower support frame and connected to the lifting frame through the lower guide wheel connecting rod. When the guide wheel slides along the guide groove, it drives the lifting frame to rise and fall.

[0013] The two ends of the connecting rod are connected to the lifting frame, which enhances the structural stability during the lifting process and ensures the smoothness of the lifting process;

[0014] The upper guide wheel connecting rod is installed on the lifting frame to enhance the stability of the guide wheel under the upper support plate when it slides along the guide groove under the upper support plate.

[0015] Furthermore, a controller is installed on the lower support frame to control the movement of the lower guide wheel connecting rod along the sliding screw, thereby driving the guide wheel to slide in the guide groove, thus realizing the control of the lifting action of the lifting frame.

[0016] Furthermore, a movable frame is installed on the lower support frame, and a motor is installed on the movable frame. Through the cooperation of the controller and the motor, power is provided for the movement of the lower guide wheel connecting rod along the sliding screw, so as to precisely control the lifting height and speed of the upper support plate.

[0017] Furthermore, the upper support plate is provided with guide plates, which are arranged opposite to each other on both sides of the upper support plate to prevent the bracket placed on the upper support plate from sliding left and right in the horizontal direction, thus ensuring the accuracy of the bracket's position.

[0018] Furthermore, the upper support plate is provided with a fixing pin, which is used to lock the bracket and prevent it from sliding back and forth in the horizontal direction, thereby enhancing the stability of the bracket placed on the upper support plate.

[0019] Furthermore, the mobile frame is equipped with a handle to provide the operator with a point of force to push the device forward.

[0020] Furthermore, the slope and size of the inclined surface of the interface on the upper support plate are adapted to the packaging box bracket slide rail to ensure that the product bracket can smoothly slide from the upper support plate into the packaging box bracket slide rail.

[0021] Working Principle: When the product packing auxiliary device is in operation, the operator holds the handle 301 on the moving frame 3 and moves the device to the designated position next to the cylindrical battery repair workbench using the casters 205 at the bottom of the lower support frame 2. The bracket carrying the cylindrical battery is placed on the upper support plate 1. The guide plates 101 on both sides of the upper support plate 1 limit the bracket, preventing it from sliding horizontally. Next, the fixing pin 102 on the upper support plate 1 is pushed inward to press against the bracket positioning plate, locking the bracket and preventing it from sliding back and forth, thus ensuring the bracket is stably placed on the upper support plate 1. Then, the handle 301 is pushed to move the device to the designated position near the packaging box 4 for packing.

[0022] The operator manipulates the controller 302 installed on the lower support frame 2 to issue a control command and start the motor 304 on the moving frame 3. The controller 302 precisely controls the operation of the motor according to the preset operating parameters. When the motor 304 receives the command, it outputs power and drives the lower guide wheel connecting rod 203 to start operating. The lower guide wheel connecting rod 203 cooperates with the sliding screw 204 installed on the lower support frame 2 and moves linearly along the sliding screw 204 under the drive of the motor power. The movement of the lower guide wheel connecting rod 203 causes the guide wheel 206 on the lifting frame 201 to slide in the corresponding guide groove 207. At the same time, it causes the guide wheel 206 above the lifting frame 201 to slide along the guide groove 207 below the upper support plate 1. As the guide wheel 206 slides in the guide groove 207, the scissor-type lifting frame 201 will expand or retract accordingly. When the guide wheel 206 slides along the guide groove 207 towards the moving frame 3, the lifting frame 201 gradually unfolds, causing the upper support plate 1 to rise; when the guide wheel 206 slides in the opposite direction along the guide groove 207, the lifting frame 201 gradually retracts, and the upper support plate 1 descends. During the lifting process of the lifting frame 201, the two ends of the connecting rod 202 are connected to the lifting frame 201, enhancing the overall stability of the lifting frame 201 and preventing it from swaying or twisting during the lifting process. At the same time, the upper guide wheel connecting rod 208 is installed on the lifting frame 201, further enhancing the stability of the guide wheel 206 below the upper support plate 1 when sliding along the guide groove 207 below the upper support plate 1, making the lifting process of the upper support plate 1 more stable and precise.

[0023] The operator observes and monitors the height of the upper support plate 1. Once it is confirmed that the inclined face interface 103 on the upper support plate 1 is aligned with the height of the tray slide 402 of the packaging box 4 and accurately aligned, the operator stops the motor 304 via the controller 302 to complete the height adjustment. The fixing pin 102 on the upper support plate 1 is then pushed outwards to disengage it from the tray positioning plate, unlocking the tray. Because the slope and dimensions of the inclined face interface 103 on the upper support plate 1 are compatible with the tray slide 402 of the packaging box, once the height adjustment is complete and accurately aligned, only a slight external force is needed for the tray to smoothly slide into the tray slide of the packaging box along the inclined face interface 103. Finally, bolts are used to secure the screw holes 501 on the tray to the corresponding screw holes on the packaging box 4, thus completing the packaging of the cylindrical batteries.

[0024] Beneficial effects:

[0025] 1. This utility model flexibly adjusts the height of the device through the lower support frame adjustment component, accurately adapting to packaging boxes of different stacking heights. This eliminates the need for frequent manual adjustments to the product height during the packing process, greatly improving packing efficiency and effectively reducing operational delays caused by height adaptation issues.

[0026] 2. The upper support plate of this utility model can stably place the product bracket, providing a stable bearing platform for the cylindrical battery, preventing the product bracket from shaking during the packing process, ensuring the safety of the product before packing, and reducing the risk of product damage due to shaking.

[0027] 3. The slope and dimensions of the inclined surface of this utility model are perfectly matched with the slide rail of the packaging box bracket, which allows the product bracket to slide smoothly into the packaging box, greatly simplifying the docking process between the bracket and the packaging box, reducing docking time, and improving packing efficiency.

[0028] 4. This utility model, through the coordinated operation of the controller and drive components, can precisely control the lifting stroke and speed of the upper support plate, achieving precise height control and ensuring that the upper support plate can accurately reach the height for docking with the packaging box tray slide, thereby improving the accuracy and reliability of the packing operation.

[0029] 5. This utility model has casters installed at the bottom of the lower support frame, which facilitates the movement of the entire device. Operators can easily move the device to the required position, whether near the maintenance workbench or the packaging box, which greatly improves the mobility of the device and saves time and manpower for handling the device.

[0030] 6. The lifting frame of this utility model adopts a scissor structure, which achieves smooth lifting with the cooperation of guide wheels and guide grooves, providing reliable support for the height adjustment of the upper support plate. Compared with the traditional lifting method, it has better stability and durability, and reduces the probability of failure.

[0031] 7. The connecting rods of this utility model are connected to the lifting frame at both ends, which enhances the structural stability of the lifting frame during the lifting process, ensures a smooth lifting process, avoids shaking or deformation of the lifting frame due to uneven force, and extends the service life of the device.

[0032] 8. Guide plates are provided on both sides of the upper support plate of this utility model, which effectively prevents the bracket placed on the upper support plate from sliding left and right, ensuring the accuracy of the bracket position, avoiding misalignment with the packaging box due to bracket sliding, and improving the packing efficiency and success rate.

[0033] 9. The upper support plate of this utility model is equipped with a fixing pin to prevent the bracket from slipping back and forth, which enhances the stability of the bracket placed on the upper support plate, making the product safer and more reliable during the packing process and reducing the risk of the product falling due to the instability of the bracket.

[0056] The technical solution will now be described in detail with reference to the accompanying drawings of the embodiments of this utility model.

[0057] Example 1

[0058] like Figure 1 , 2 As shown, a product packing auxiliary device includes: an upper support plate 1, a guide plate 101, a fixing pin 102, an inclined face interface 103, a lower support frame 2, a lifting frame 201, a connecting rod 202, a lower guide wheel connecting rod 203, a sliding screw 204, a universal wheel 205, a guide wheel 206, a guide groove 207, an upper guide wheel connecting rod 208, a moving frame 3, a handle 301, a controller 302, and a motor 304;

[0059] like Figure 3 As shown, the lifting frame 201 is installed on the lower support frame 2. The lifting frame bracket 201 is a scissor structure, with one end connected to the upper support plate bracket 1 and the other end connected to the lower support frame bracket 2. It is used to adjust the height of the packing auxiliary device. The upper support plate 1 is installed above the lifting frame 201 and is used to place the bracket 5. The upper support plate bracket 1 is provided with a slanted face interface bracket 103 to facilitate the docking of the support plate bracket 1 with the packaging box 4 bracket slide 402. The bottom of the lower support frame bracket 2 is equipped with a universal wheel bracket 205 to realize the overall position movement of the packing auxiliary device.

[0060] like Figure 1 , 2 As shown, guide rail brackets 207 are respectively positioned above the lower support bracket 2 and below the upper support plate bracket 1; two sets of guide wheel brackets 206 are provided, respectively installed above and below the lifting frame bracket 201. The guide wheel bracket 206 above the lifting frame bracket 201 is slidably connected to the guide rail bracket 207 below the upper support plate bracket 1, and the guide wheel bracket 206 below the lifting frame bracket 201 is slidably connected to the guide rail bracket 207 above the lower support bracket 2; the sliding engagement between the guide wheel bracket 206 and the guide rail bracket 207 provides guidance for the lifting of the lifting frame bracket 201.

[0061] The sliding screw bracket 204 is installed on the lower support bracket 2 and is connected to the lifting bracket 201 through the lower guide wheel connecting rod bracket 203. When the guide wheel bracket 206 slides along the guide groove bracket 207, it drives the lifting bracket 201 to rise and fall.

[0062] The two ends of the connecting rod bracket 202 are connected to the lifting frame bracket 201, which enhances the structural stability during the lifting process of the lifting frame bracket 201 and ensures the smoothness of the lifting process.

[0063] like Figure 2 As shown, the upper guide wheel connecting rod bracket 208 is installed on the lifting frame bracket 201 to enhance the stability of the guide wheel bracket 206 below the upper support plate bracket 1 when it slides along the guide groove bracket 207 below the upper support plate bracket 1.

[0064] like Figure 3 As shown, the controller 302 is mounted on the support bracket 2 and is used to control the lower guide wheel connecting rod bracket 203 to move along the sliding screw bracket 204, thereby driving the guide wheel bracket 206 to slide in the guide groove bracket 207, so as to control the lifting action of the lifting bracket 201.

[0065] The movable frame bracket 3 is installed on the lower support frame bracket 2. The movable frame bracket 3 is equipped with a motor bracket 304. Through the cooperation of the controller bracket 302 and the motor bracket 304, the lower guide wheel connecting rod bracket 203 is powered to move along the sliding screw bracket 204, and the lifting height and speed of the upper support plate bracket 1 are precisely controlled.

[0066] like Figure 1 As shown, the guide plate bracket 101 is mounted on the support plate bracket 1. The guide plate bracket 101 is positioned opposite to the upper support plate bracket 1 on both sides to prevent the bracket placed on the upper support plate bracket 1 from sliding left and right in the horizontal direction, thus ensuring the accuracy of the bracket's position.

[0067] like Figure 7 As shown, the fixing pin bracket 102 is mounted on the upper support plate bracket 1. The fixing pin bracket 102 is used to hold the bracket in place and prevent it from sliding back and forth in the horizontal direction, thereby enhancing the stability of the bracket placed on the upper support plate bracket 1.

[0068] like Figure 3 As shown, the handle bracket 301 is mounted on the movable frame bracket 3 to provide the operator with a point of force to move the device.

[0069] like Figure 11As shown, the inclined face interface bracket 103 is mounted on the upper support plate bracket 1, and its slope and size are adapted to the packaging box 4 bracket slide 402 to ensure that the bracket 5 can smoothly slide from the upper support plate bracket 1 into the packaging box 4 bracket slide 402.

[0070] like Figure 8-11 As shown, when the product packing auxiliary device is in operation, the operator holds the handle 301 on the moving frame 3 and, with the help of the casters 205 at the bottom of the lower support frame 2, moves the packing auxiliary device to a designated position next to the maintenance workbench near the cylindrical battery 6. The bracket 5 carrying the cylindrical battery 6 is placed on the upper support plate 1. The guide plates 101 arranged opposite each other on both sides of the upper support plate 1 will limit the bracket 5 and prevent the bracket 5 from sliding left and right in the horizontal direction. The fixing pin 102 on the upper support plate 1 is pushed inward to press against the bracket positioning plate 502, locking the bracket 5 and preventing it from sliding back and forth, thereby ensuring that the bracket 5 is stably placed on the upper support plate 1. Then, the handle 301 is pushed to move the device to the designated position for packing near the packaging box 4.

[0071] The operator manipulates the controller 302 installed on the lower support frame 2 to issue a control command and start the motor 304 on the moving frame 3. The controller 302 precisely controls the operation of the motor according to the preset operating parameters. When the motor 304 receives the command, it outputs power and drives the lower guide wheel connecting rod 203 to start operating. The lower guide wheel connecting rod 203 cooperates with the sliding screw 204 installed on the lower support frame 2 and moves linearly along the sliding screw 204 under the drive of the motor power. The movement of the lower guide wheel connecting rod 203 causes the guide wheel 206 on the lifting frame 201 to slide in the corresponding guide groove 207. At the same time, it causes the guide wheel 206 above the lifting frame 201 to slide along the guide groove 207 below the upper support plate 1. As the guide wheel 206 slides in the guide groove 207, the scissor-type lifting frame 201 will expand or retract accordingly. When the guide wheel 206 slides along the guide groove 207 towards the moving frame 3, the lifting frame 201 gradually unfolds, causing the upper support plate 1 to rise; when the guide wheel 206 slides in the opposite direction along the guide groove 207, the lifting frame 201 gradually retracts, and the upper support plate 1 descends. During the lifting process of the lifting frame 201, the two ends of the connecting rod 202 are connected to the lifting frame 201, enhancing the overall stability of the lifting frame 201 and preventing it from swaying or twisting during the lifting process. At the same time, the upper guide wheel connecting rod 208 is installed on the lifting frame 201, further enhancing the stability of the guide wheel 206 below the upper support plate 1 when sliding along the guide groove 207 below the upper support plate 1, making the lifting process of the upper support plate 1 more stable and precise.

[0072] The operator observes and monitors the height of the upper support plate 1. Once it is confirmed that the inclined face interface 103 on the upper support plate 1 is aligned with the height of the tray slide 402 of the packaging box 4 and accurately aligned, the operator stops the motor 304 via the controller 302 to complete the height adjustment. The fixing pin 102 on the upper support plate 1 is then pushed outwards to disengage it from the tray positioning plate 502, unlocking the tray 5. Because the slope and dimensions of the inclined face interface 103 on the upper support plate 1 are compatible with the tray slide 402 of the packaging box, once the height adjustment is complete and accurately aligned, only a slight external force is needed for the tray 5 to smoothly slide into the tray slide 402 of the packaging box along the inclined face interface 103. Finally, bolts are used to secure the tray 5 with the corresponding bolt holes 501 on the packaging box 4, thus completing the packaging of the cylindrical battery 6.
