Description

Technical Field

[0001] This utility model belongs to the field of battery production equipment technology, specifically relating to a box-loading device suitable for battery packs of different sizes. Background Technology

[0002] In the large-scale production process of new energy power batteries, the packaging process after battery pack assembly is a core step in ensuring the safety of battery pack transportation and storage. This process requires the smooth transfer of the battery pack into the packaging box, and there are rigid requirements for the accuracy and efficiency of the packaging operation. If the battery pack collides with the inner wall of the packaging box or if there is a positioning deviation during the packaging process, it will directly lead to damage to the outer shell of the battery pack and damage to the internal cells, resulting in product quality defects and subsequent safety hazards. Inefficient packaging operations will create a bottleneck in production line capacity and restrict the improvement of the efficiency of large-scale production.

[0003] With the iteration of power battery technology, the size and weight parameters of different battery pack specifications (such as the Pack 2.0 series and Pack 3.0 series) vary significantly. Specifically, the Pack 3.0 battery pack is 50-80mm longer, 30-50mm wider, and 10-15kg heavier than the Pack 2.0. Furthermore, in actual production scenarios, there are differences in the stacking height of packaging boxes and the height of production line conveyors, and the required loading height for different battery pack specifications varies, further posing diverse requirements for the height adaptability of the loading device.

[0004] A review of existing technologies revealed two major technical deficiencies in current battery pack loading devices: First, low loading accuracy and operational efficiency. Some devices lack reliable positioning and guiding mechanisms, leading to battery pack misalignment and jamming during transport to the packaging box. This not only reduces the number of packs loaded per unit time but also fails to guarantee precise centered placement within the box, significantly increasing the risk of damage. Second, limited height adaptability. Existing battery pack loading devices often employ fixed-height designs or only allow for minor height adjustments through mechanical disassembly, failing to flexibly adapt to diverse height requirements in different scenarios. Even those few devices with height adjustment capabilities suffer from cumbersome and time-consuming processes. Furthermore, limited by their single-specification compatibility, switching battery pack specifications requires 2-3 operators to disassemble and replace core components such as the positioning unit and conveyor rollers, taking 1.5-2 hours and disrupting production. This reduces overall production efficiency and increases labor costs and component wear probability.

[0005] The aforementioned technical deficiencies mean that existing battery pack loading devices cannot meet the flexible production requirements of precise loading, efficient operation, and wide range of height adaptability in large-scale production. Utility Model Content

[0057] The application principle of this utility model will be described in detail below with reference to the accompanying drawings.

[0058] Example 1

[0059] This invention provides a battery pack loading device suitable for different sizes, such as... Figures 1-4 As shown, it includes:

[0060] Mounting base 1;

[0061] The lifting assembly 4 is connected to the mounting base 1 and can be raised and lowered relative to the mounting base 1 in the Z-axis direction;

[0062] A positioning component is provided on the top surface of the lifting component 4, including multiple coaxially arranged positioning units. Each positioning unit extends along the X-axis direction and is detachably connected to the lifting component 4, and is used to position battery packs of different sizes.

[0063] The conveying component is slidably connected to the lifting component 4 and can move along the lifting component 4 in the X-axis direction to push the battery pack located in the positioning unit into the box.

[0064] The detection component is used to detect whether the lifting component 4 and the conveying component have moved to the preset position;

[0065] The control unit 7 is connected to the lifting assembly 4, the detection assembly, and the conveying assembly, respectively.

[0066] Based on the above solution, when positioning (i.e., limiting) large-sized battery packs is required, the positioning unit used for positioning smaller-sized packs can be directly removed. This enables precise placement of battery packs of different sizes into the box without disassembling or replacing core components. Specification switching takes only 15-20 minutes, significantly reducing changeover time, minimizing production interruptions, and greatly improving the efficiency of the box-loading operation. Furthermore, the detection components can monitor the positions of the lifting assembly 4 and the conveying assembly in real time, and work in conjunction with the control unit 7 to coordinate the control of the lifting assembly 4 and the conveying assembly. This allows for precise placement of battery packs of different sizes into the box and effectively improves the stability and safety of the box-loading process, preventing battery pack collision damage.

[0067] In one specific embodiment of this utility model, such as Figure 3 As shown, each positioning unit has the same structure and includes:

[0068] The first positioning plate 19 and the second positioning plate 20 are positioned opposite each other, and the distance between them is consistent with the width of the battery pack to be placed in the box.

[0069] The lateral positioning block 21 is connected to the conveying assembly and is used to contact the end of the battery pack to be placed in the box along its length.

[0070] In the above scheme, the structure of the positioning unit is specifically defined. In the specific implementation process, the first positioning plate 19 and the second positioning plate 20 are both perpendicular to the top surface of the lifting assembly 4. The top surface of the lifting assembly 4 is provided with several positioning holes (not shown in the figure). The first positioning plate 19 and the second positioning plate 20 can be detachably connected to the top surface of the lifting assembly 4 by the cooperation of bolts with the positioning holes. When it is necessary to position (i.e. limit) a large-sized battery pack, the bolts on the first positioning plate 19 and the second positioning plate 20 included in the corresponding small-sized positioning unit can be removed directly without disassembling and replacing the core components. The specification switch only takes 15-20 minutes, which greatly shortens the switchover time and reduces production interruption. The number of the transverse positioning blocks 21 is preferably an even number (such as 4 or 6). The even number of transverse positioning blocks 21 are symmetrically arranged to facilitate the cooperation of the conveying assembly to push the battery pack to slide along the X-axis direction in the positioning unit. For example, when it is necessary to adapt to both Pack 2.0 and Pack 3.0 battery packs at the same time, only two sets of positioning units need to be set up. In one set of positioning units, the distance between the first positioning plate 19 and the second positioning plate 20 is adapted to the width of the Pack 2.0 battery pack; in the other set of positioning units, the distance between the first positioning plate 19 and the second positioning plate 20 is adapted to the width of the Pack 3.0 battery pack.

[0071] In one specific embodiment of this utility model, the lateral positioning block 21 is made of a flexible material.

[0072] In the above solution, by making the material of the lateral positioning block 21 a flexible material, the end of the battery pack can be buffered and positioned to avoid collision damage to the battery pack. In specific implementation, the lateral positioning block 21 can be made of rubber or other materials with flexible properties, which can be selected according to actual needs.

[0073] In one specific embodiment of this utility model, the conveying assembly includes a conveying frame 22 and a conveying frame and a conveying assembly driving component. The conveying frame 22 is provided with a sliding groove for cooperating with the sliding rail provided on the lifting assembly 4.

[0074] The conveying component drive unit is mounted on the lifting component 4, and its output end is connected to the conveying frame to drive the conveying frame to slide along the X-axis on the lifting component. Its control end is connected to the control unit 7. In specific implementation, the conveying component drive unit can be implemented by an electric cylinder.

[0075] In the above scheme, the structure of the conveying assembly is specifically defined. The conveying frame 22 extends along the Y-axis and is perpendicular to the transverse positioning block 21. By providing a sliding groove at the bottom of the conveying frame 22, it can be slidably connected with the lifting assembly 4. The conveying assembly driving component drives the conveying frame 22 to move.

[0076] In one specific embodiment of this utility model, such as Figure 1 As shown, the lifting assembly 4 includes:

[0077] The lifting platform 8 is equipped with a slide rail for cooperating with the slide groove on the conveyor frame 22;

[0078] The lead screw drive component 3 is mounted on the mounting base 1, and its control end is electrically connected to the control unit 7.

[0079] The lifting screw 23 is connected to the screw drive component 3 and the lifting platform 8. The screw drive component 3 drives the lifting screw 23 to adjust the height of the lifting platform 8 (i.e., controls the movement of the lifting platform 8 in the Z-axis direction), thereby adjusting the height of the battery pack entering the box. In specific implementation, the screw drive component 3 includes a lifting motor 12 and multiple steering gears 25 connected to the lifting motor 12. Each steering gear 25 is connected to its corresponding lifting screw 23.

[0080] In the above solution, the structure of the lifting component 4 is specifically defined, which can lift the battery pack to a specified height, cover a wider range of box entry heights, automatically lift and lower to a specified height position, accurately connect with packaging boxes of different stacking heights, and adapt to diverse production scenario needs.

[0081] In one specific embodiment of this utility model, such as Figure 3As shown, the lifting platform 8 is also provided with a number of rollers 24 arranged sequentially along the X-axis at the part corresponding to the positioning unit. The rollers 24 are used to support the battery pack to be put into the box.

[0082] In the above solution, the roller 24 is used in conjunction with the conveying component to reduce the resistance of pushing the battery pack and improve the pushing efficiency.

[0083] In one specific embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the battery pack loading device further includes a support leg assembly 5, which includes:

[0084] The support leg is connected to the mounting base 1;

[0085] The outrigger drive component has its output end connected to the outrigger (the connection between the two is existing technology and will not be described in detail in this utility model), and is used to drive the outrigger to move the mounting base 1 up and down in the Z-axis direction. Its control end is electrically connected to the control unit 7.

[0086] In the above solution, the lifting component 4 and the support leg assembly 5 work together to lift the battery pack to be placed in the box to a preset height, which can cover a wider range of box placement heights, automatically lift and lower to a specified height position, accurately connect to packaging boxes of different stacking heights, and adapt to the needs of diverse production scenarios.

[0087] In one specific embodiment of this utility model, such as Figure 1 As shown, the detection component includes: a leg proximity switch 9, which is installed on the extension and retraction path of the leg, and its output terminal is electrically connected to the control unit 7. The leg proximity switch 9 is used to detect the extension and retraction distance of the leg in real time, and when the leg reaches the set extension and retraction amount, it feeds back a signal to the control unit 7.

[0088] In the above scheme, the outrigger proximity switches 9 can prevent overtravel and achieve precise height positioning. In specific implementation, the outrigger assembly 5 includes four outriggers, defined as outrigger 1, outrigger 2, outrigger 3, and outrigger 4. Outriggers 1-4 correspond to the left front outrigger, left rear outrigger, right front outrigger, and right rear outrigger, respectively. Each outrigger is installed at one of the four corners of the mounting base 1. The outrigger assembly 5 uses the extension and retraction of each outrigger to assist in adjusting the overall height and leveling of the container. Four outrigger proximity switches 9 are correspondingly provided, defined as: outrigger 1 retracted position proximity switch K7, outrigger 2 retracted position proximity switch K8, outrigger 3 retracted position proximity switch K9, and outrigger 4 retracted position proximity switch K10. Each proximity switch is installed on the corresponding outrigger, preferably at the bottom of each outrigger, to detect the outrigger retracted position signal and feed it back to the control unit 7.

[0089] In one specific embodiment of this utility model, such as Figures 1-2 As shown, the detection component includes:

[0090] The limit switch 6, which is installed on the mounting base 1, is used to detect whether the lifting assembly 4 has been raised to the preset position and to feed the detection result back to the control unit 7.

[0091] And / or, the limit switch 18, which is installed at the bottom of the mounting base 1, is used to detect whether the lifting assembly 4 has fallen to the preset position and to feed the detection result back to the control unit 7;

[0092] And / or, the grating sensor 2 is installed around the mounting base 1 to detect the entry of an object into the box device and to provide feedback to the control unit 7; in specific implementation, the grating sensor 2 is preferably installed on the entrance side of the entire box device to detect whether the battery pack has entered the conveying area.

[0093] And / or, laser light 16, installed on the edge of lifting assembly 4, to detect whether the lifting assembly is in a horizontal state;

[0094] And / or, receive the position limit switch 17, which is installed on the conveying assembly, to detect whether the conveying assembly has moved to the preset recycling position and to feed back to the control unit 7;

[0095] And / or, a push-to-position proximity switch 15 is installed on the conveying assembly to detect whether the conveying assembly has moved to a preset working position and to provide feedback to the control unit 7; the retraction position and the working position are the two ends of the moving path of the conveying assembly along the X-axis, respectively; in the specific implementation process, the receive-to-position limit switch 17 and the push-to-position proximity switch 15 are respectively installed at the extension limit position of the conveying assembly drive component 10 to detect the state of the conveying frame 22 being pushed to the working position and retracted to the initial position, respectively, to ensure accurate positioning.

[0096] The above solution enables precise positioning of the lifting component 4 and the conveying component, facilitating the accurate placement of the battery pack into the container.

[0097] In one specific embodiment of this utility model, the mounting base includes: a mounting frame, and a base plate with a hollow structure located below the mounting frame; the battery pack loading device further includes: a lifting component drive component 11;

[0098] The lifting component drive unit 11 is mounted on the base plate, and its output end is connected to the mounting frame to drive the lifting component to move along the Y-axis direction with the conveying component; in specific implementation, the lifting component drive unit 11 can be implemented by a motor.

[0099] The detection component includes:

[0100] The first stop limit switch 14 is installed on the lifting assembly 4 and is used to detect whether the conveying assembly has run to the preset first stop position in the Y-axis direction and to feed the detection result back to the control unit 7.

[0101] And / or, the second stop limit switch 13 is installed on the lifting assembly 4 to detect whether the conveying assembly has moved to the preset second stop position in the Y-axis direction and to feed back the detection result to the control unit 7; the first stop position and the second stop position are respectively set on both sides of the lifting assembly 4, and are the two ends of the moving path of the conveying assembly along the Y-axis; when the conveying assembly moves to the extreme positions on both sides in the Y-axis direction, the first stop limit switch 14 or the second stop limit switch 13 is triggered and the power supply of the lifting assembly drive component 11 is cut off to prevent overtravel damage.

[0102] In the above scheme, the position of the battery pack in the Y-axis direction can be adjusted by using the lifting component drive component 11 so as to better utilize the conveying component to push the battery pack into the box.

[0103] In one specific embodiment of this utility model, the control unit 7 includes a main control box and an operation panel. The main control box is installed on one side of the mounting base 1 and contains a PLC controller. The operation panel is embedded in the surface of the main control box and has specification selection buttons (such as Pack 2.0 button and Pack 3.0 button), start / stop buttons, and a parameter display area. The PLC controller is electrically connected to the detection component, the conveying component, the lifting component 4, and the support leg assembly 5 to realize automated control and status monitoring of the device.
