[0053] Example 1

[0054] like Figures 1 to 10As shown in the illustration, this application provides a battery assembly auxiliary vehicle 01, including: a frame 011, multiple floor wheels 012, and multiple track wheels 013. A battery guide seat a and a battery positioning seat b are provided on the frame 011. Each floor wheel 012 is rotatably disposed on the bottom of the frame 011, and each track wheel 013 is rotatably disposed on the bottom of the frame 011. Each track wheel 013 includes a wheel body and a track limiting edge disposed at one end of the wheel body. Specifically, in the direction perpendicular to the frame 011, the distance between the track wheel 013 and the frame 011 is less than the distance between the floor wheels 012 and the frame 011.

[0055] The battery assembly auxiliary vehicle 01 provided in this application can move sequentially to various loading areas on the production line to assemble different parts of the battery box 100, significantly improving assembly efficiency. The battery box production line can include guide rails 02, and the frame 011 is equipped with floor wheels 012 and track wheels 013, supporting both movement on the guide rails 02 and on the ground, expanding the driving area of ​​the auxiliary vehicle 01 and solving the problem of difficult transfer without a track. The battery assembly auxiliary vehicle 01 of this application is safe, efficient, lightweight, and flexible. By setting a battery guide seat a, the battery box can be easily hoisted and placed; by setting a battery positioning seat b, the battery box can be stably supported, ensuring product quality and production safety from the source. At the same time, it greatly shortens the process connection time and significantly improves the production cycle.

[0056] The guide rail 02 has an I-shaped cross-section, including two flanges and a web plate located between the two flanges. The cylindrical surface of the wheel body of the track wheel 013 is supported on the upper surface of the flange, while the track limiting edge is located on one side of the flange along the width direction to cooperate with the flange limiting edge. The structure of the track wheel and the cooperation structure between the guide rail 02 and the track wheel 013 are widely disclosed in the prior art, and their structures will not be described in detail in this application.

[0057] The lower edge of the track wheel 013 is higher than the landing wheel 012. When the battery assembly auxiliary vehicle 01 is traveling on the ground, the landing wheel 012 is supported on the ground. When the battery assembly auxiliary vehicle 01 is traveling on the guide rail 02, the track wheel 013 is supported on the guide rail 02, while the landing wheel 012 is suspended in the air.

[0058] The battery guide seat a has a guide ramp, which is used to guide the bottom frame of the battery box as it is placed on the frame 011 from top to bottom, so that the bottom frame 11 of the battery box can be smoothly supported on the appropriate part of the frame 011.

[0059] Positioning holes can be provided on the bottom frame 11. When the bottom frame 11 of the battery box is placed on the frame 011, the battery positioning seat b and the positioning hole are inserted and engaged to position the bottom frame 11 of the battery box, so that the battery box is stably supported on the frame 011 and will not tip over.

[0060] In some possible implementations, each of the track wheels 013 is arranged on both sides of each of the ground wheels 012 along the width direction of the frame 011. The ground wheels 012 are located in the middle, while the track wheels 013 are located on both sides of the ground wheels 012, with the ground wheels 012 positioned between each of the track wheels 013. The spacing between the ground wheels 012 is small along the width direction of the frame 011, making the vehicle body move more flexibly and turn more easily, without affecting the arrangement of the track wheels 013.

[0061] In some possible implementations, the frame 011 has four corners, and a track wheel 013 and a ground wheel 012 are respectively provided at each of the four corners of the frame 011. The frame 011 is generally rectangular, and the track wheel 013 and ground wheel 012 at each of the four corners enable the vehicle to move smoothly whether it is on the ground or on the guide rail 02.

[0062] In some possible implementations, the battery assembly auxiliary vehicle 01 includes an extension rod 014, which is disposed at both ends of the frame 011 along the direction of travel. When the battery box is seated on the frame 011, the extension rod 014 extends out of the battery box.

[0063] In this implementation scheme, extension rods 014 are respectively provided at both ends of the frame 011 along its length direction, which can forcibly limit the distance between adjacent battery assembly auxiliary vehicles 01 and avoid rigid collisions between battery boxes on adjacent battery assembly auxiliary vehicles 01.

[0064] In some possible implementations, the extension rod 014 includes a rod body and a buffer element, with one end of the rod body fixed to the frame 011 and the buffer element disposed at the other end of the rod body. The buffer element can be made of rubber, silicone, a spring plate, or other structural components. This application does not limit the specific structure of the buffer element.

[0065] In some possible implementations, at least two battery guide seats a are provided along the edge of the frame 011. Each battery guide seat a includes a support plate a1 and a guide block a2, both of which are mounted on the frame 011. The guide block a2 is located on one side of the support plate a1, and the side of the guide block a2 facing the support plate a1 has an inclined guide surface. The inclined guide surface guides the bottom frame 11 of the falling battery box, ensuring that the battery frame 031 ultimately rests on the support plate a1.

[0066] In some possible implementations, the battery positioning seat b includes a base and a guide post b3. The base is disposed on the vehicle frame 011, and the guide post b3 is disposed on the base. At least one end of the guide post b3 opposite to the base has a guide portion, wherein the outer diameter of the guide portion gradually decreases in the direction from the base to the guide post b3. The guide portion is generally cone-shaped, allowing for easy insertion into a positioning hole on the bottom frame 11.

[0067] In some possible implementations, the battery assembly auxiliary vehicle 01 includes a first fixing auxiliary component c and a second fixing auxiliary component d. The base includes a base plate b1 and a seat body b2. The base plate b1 is fixed to the frame 011. The base plate b1 has a first directional groove b11, through which fasteners pass and are connected to the frame 011. The first fixing auxiliary component c is fixed to the frame 011 and is connected to a first directional limiting rod (not shown), which abuts against the base plate b1. Similarly, the seat body b2 has a second directional groove b21, through which fasteners pass and are connected to the base plate b1. The second fixing auxiliary component d is fixed to the base plate b1 and is connected to a second directional limiting rod (not shown), which abuts against the seat body b2. A guide post b3 is connected to the seat body b2.

[0068] The fastener can be a bolt. The first directional groove b11 can have at least two sections. If the fastener is not securely fixed, the base plate b1 may move along the first direction. The first directional limiting rod extends in the same direction as the first directional groove and abuts against the base plate b1, restricting its movement and improving its installation accuracy and reliability. A through hole can be provided on the first fixing auxiliary component c, through which the first directional limiting rod passes. The first directional limiting rod has external threads, on which two nuts can be threaded. The two nuts are located on opposite sides of the first fixing auxiliary component c. By tightening the two nuts, the extension length of the first directional limiting rod can be adjusted, ensuring that the first directional limiting rod accurately abuts against the base plate b1.

[0069] Similarly, the second directional groove b21 has at least two sections. When the fastener is not securely fixed, the base may move along the second direction. The second directional limiting rod extends in the same direction as the second directional groove and abuts against the base b2, thus limiting the movement of the base b2 and improving the installation accuracy and reliability of the base b2. A through hole can be provided on the second fixing auxiliary component d, through which the second directional limiting rod passes. The second directional limiting rod has external threads, on which two nuts can be threaded. The two nuts are located on both sides of the second fixing auxiliary component d. By tightening the two nuts, the extension length of the second directional limiting rod can be adjusted, so that the second directional limiting rod accurately abuts against the base b2.

[0070] The installation accuracy of the guide post b3 is improved by the inclusion of the first fixing auxiliary component c and the second fixing auxiliary component d. The guide post b3 is connected to the base body b2, and the guide post b3 can be integrally formed with the base body b2. The first directional limiting rod and the second directional limiting rod are perpendicular to each other. A tapered guide portion can be provided at the top of the guide post b3.

[0071] In some possible implementations, the battery assembly auxiliary vehicle 01 includes multiple push rods 015, each of which is vertically connected to the upper surface of the frame 011. The lower surface of the frame 011 is provided with insertion holes 0111. Multiple battery assembly auxiliary vehicles 01 can be stacked sequentially along the height direction. In two adjacent battery assembly auxiliary vehicles 01, the end of one's push rod 015 is inserted into the insertion hole 0111 of the other. The ability to stack multiple battery assembly auxiliary vehicles 01 sequentially along the height direction reduces space occupation and facilitates storage and transportation.

[0072] In some possible implementations, the battery assembly auxiliary vehicle 01 includes a force-applying frame 016, which is detachably connected to the frame 011. When the battery assembly auxiliary vehicle 01 moves to a structure detached from the guide rail 02 and without a battery box, the force-applying frame 016 can be installed to facilitate gripping and applying force to move the battery assembly auxiliary vehicle 01. The force-applying frame 016 may include a riser tube, which is sleeved on a top rod 015 when the force-applying frame 016 is connected to the frame 011. The riser tube does not require any other connecting structure to the frame 011, making the assembly and disassembly of the force-applying frame 016 and the frame 011 simpler and more convenient to use.

[0073] Example 2

[0074] like Figures 1 to 10 As shown, this application embodiment provides a battery box production line, including: a guide rail 02, two side frames 03, a lifting guide block 04, and several assembly mechanisms. The guide rail 02 is disposed on a supporting surface (such as the ground). The two side frames 03 are each located at one end of the guide rail 02 and are respectively disposed on both sides of the guide rail 02 along its width direction, forming a connecting channel between the two side frames 03. Multiple rollers 033 are disposed on the opposite side of each of the two side frames 03. The lifting guide block 04 is disposed at the end of the guide rail 02 and is located between the two side frames 03. The lifting guide block 04 has a lifting guide surface 042 extending from one side of the supporting surface towards the top of the guide rail 02. Each of the assembly mechanisms is arranged sequentially along the length direction of the guide rail 02.

[0075] The battery box production line of this application has a guide rail 02, which facilitates the movement of the battery assembly auxiliary vehicle 01 along the guide rail 02 and sequentially to each assembly mechanism, so as to cooperate with the assembly mechanism to assemble the various parts of the battery box in sequence, which significantly improves the assembly efficiency.

[0076] In this application, the two side frames 03 form a connecting channel in the middle, guiding the battery assembly auxiliary vehicle 01 and restricting its horizontal position, ensuring that the track wheels 013 of the battery assembly auxiliary vehicle 01 are aligned horizontally with the guide rail 02. The lifting guide block 04 provides vertical guidance, allowing the battery assembly auxiliary vehicle 01 to move upwards along the lifting guide block 04 and smoothly support the track wheels 013 on the guide rail 02. In this application, the lifting guide block 04 and the two side frames 03 guide the battery assembly auxiliary vehicle 01, enabling it to move smoothly from the ground onto the guide rail 02.

[0077] In some possible implementations, the side frame 03 has a frame 031 and a guide body 032. The frame 031 is located on one side of the guide rail 02, and the guide body 032 is disposed on the side of the frame 031 close to the guide rail 02. The guide body 032 extends along the length direction of the guide rail 02, and each roller 033 is disposed on the guide body 032, and the rollers 033 are arranged sequentially along the length direction of the guide body 032. After the battery assembly auxiliary vehicle 01 moves to the rail connection channel, it contacts the corresponding rollers 033 on both sides along the width direction, changing the original sliding contact with the guide body 032 into rolling contact, reducing wear, significantly reducing frictional resistance, reducing manpower requirements, and saving manpower.

[0078] In some possible implementations, the guide body 032 has a guide segment 03212 at least at one end away from the guide rail 02, and the distance between the guide segment 03212 and the extension line of the guide rail 02 gradually increases in the direction from the guide rail 02 to the guide body 032.

[0079] The spacing between the guide sections 03212 of the guide bodies 032 on both sides of the guide rail 02 gradually decreases, which is beneficial for the battery assembly auxiliary vehicle 01 to be gradually and precisely adjusted in position as it travels along the rail connection channel, so that each track wheel 013 is aligned with the two rails of the guide rail 02.

[0080] In some possible implementations, the guide body 032 includes two guide plates 0321, which are arranged sequentially along the height direction of the frame 031. The roller 033 includes a wheel body 0331 and a shaft body 0332, with the wheel body 0331 located between the two guide plates 0321 and the two ends of the shaft body 0332 connected to the two guide plates 0321 respectively.

[0081] In this embodiment, both guide plates 0321 are horizontally arranged, with their thick end faces facing away from the frame 031 close to the battery assembly auxiliary vehicle 01. The two guide plates 0321 are spaced apart along the height of the frame 031, forming a gap between them to accommodate the wheel 0331. Part of the wheel 0331 is located in the gap between the two guide plates 0321, and part of the wheel 0331 protrudes from the two guide plates 0321 to facilitate rolling contact with the frame 011 of the battery assembly auxiliary vehicle 01.

[0082] In some possible implementations, the guide plate 0321 is provided with a plurality of notches 03211 along the length direction, and the two ends of the shaft 0332 pass through the notches on the two guide plates 0321 respectively.

[0083] By providing notches 03211, it is convenient for both ends of the shaft 0332 to be mounted on the two guide plates 0321. The shaft 0332 can be mounted on the notches 03211, while the wheel 0331 is rotatably mounted on the shaft 0332. Alternatively, the shaft 0332 can be rotatably connected to the corresponding notch, while the wheel 0331 is fixed to the shaft 0332.

[0084] For example, a cap is provided at one end of the shaft 0332, and an external thread is provided at the other end. The middle of the shaft 0332 is a smooth shaft. The shaft 0332 passes through the notch 03211 of two guide plates 0321. The cap is confined on one of the guide plates 0321, and a nut is threadedly connected to the end of the shaft 0332 with the external thread, and the nut is confined on the other guide plate 0321. A washer can be provided between the nut and the corresponding guide plate 0321. A wheel 0331 is rotatably fitted onto the smooth shaft.

[0085] In some possible implementations, frame 031 includes an upper frame and a plurality of legs vertically connected to the upper frame. A guide 032 is located on the side of the upper frame near the guide rail 02 and is fixed to the upper frame. The bottom of the legs can be secured to the ground with fasteners. The arrangement of the legs increases the height of the upper frame and guide plate 0321 to match the frame 011 of the battery assembly auxiliary vehicle 01.

[0086] In some possible implementations, the battery box production line includes two lifting guide blocks 04, and the guide rail 02 includes two rails spaced apart. The two lifting guide blocks 04 are respectively disposed at the ends of the two rails, and the lifting guide surfaces 042 on the two lifting guide blocks 04 extend toward the top of the two rails respectively.

[0087] The lifting guide surface 042 is at least partially an inclined surface that gradually extends upwards. The lower edge of the lifting guide surface 042 is higher than the support surface, which can be understood as the ground. The track wheel 013 can contact the lower edge of the lifting guide surface 042 when the ground wheel of the battery assembly auxiliary vehicle 01 is in contact with the support surface.

[0088] In some possible implementations, a transition surface 041 is provided at the top of one end of the lifting guide block 04 near the rail. The transition surface 041 is flush with or has a small height difference from the upper surface of the rail, and the end of the lifting guide surface 042 is connected to the transition surface 041. The transition surface 041 can be a straight surface, with a height flush with or similar to the upper surface of the rail. When the track wheel 013 is supported on the transition surface 041, it can easily and smoothly roll onto the upper surface of the rail (or guide rail 02).

[0089] In some possible implementations, the battery box production line includes process equipment, which comprises multiple industrial computer platforms arranged sequentially along the length of the guide rail 02. Each industrial computer platform has an identification device for identifying materials. The industrial computer platforms can be located in various loading areas on the guide rail 02, and during or after the loading and assembly process, the identification device identifies the corresponding material workpieces to record each assembly process.

[0090] In some possible implementations, the battery box production line includes a battery assembly auxiliary vehicle 01 having track wheels 013 that are rotatably supported on the guide rail 02.

[0091] Example 3

[0092] like Figures 1 to 10 As shown in the illustration, this application provides a battery testing station 07, including a first bracket 071, a second bracket 072, and a charge / discharge integrated machine 073. The first bracket 071 is provided with a battery positioning seat b, a charging interface 0711, and a discharging interface 0712. When the test battery box 100a is seated on the first bracket 071, the battery positioning seat b and the test battery box 100a are in a limiting fit, and the charging interface 0711 and the discharging interface 0712 are electrically connected to the test battery box 100a. The second bracket 072 is provided with a test-fit battery box 100b. The charge / discharge integrated machine 073 has several charging ports, some of which are detachably connected to the charging interface 0711 or the discharging interface 0712, and some of which are electrically connected to the test-fit battery box 100b to perform power transfer between the test-fit battery box 100b and the test battery box 100a.

[0093] The test battery box 100b can be a larger energy storage battery, for example, a specially manufactured large-size battery box, or a reused energy storage battery box used in heavy-duty trucks. The test battery box 100b can include a frame and multiple battery packs housed within the frame. This test battery box 100b can be a new battery box or an existing one, as long as the stored energy meets the charge-discharge test requirements.

[0094] The charge / discharge integrated machine 073 uses a bidirectional energy conversion system to achieve mutual energy transfer between the test battery box 100a and the test auxiliary battery box 100b, enabling charging and discharging of the test battery box 100a. The charging / discharging integrated machine 073 includes a power-taking gun and a power-discharging gun. During discharge testing, the test battery box 100a is first hoisted onto the first bracket 071. An external debugging harness and CAN module are used to establish a communication connection between the test computer and the test battery box 100a, facilitating control and data acquisition. Power is drawn from the charging / discharging unit 073 by connecting its power-taking gun to the discharge interface 0712 on the first bracket 071. The discharge gun of the charging / discharging unit 073 is then connected to the test battery box 100b for energy recovery. The test computer sends a discharge command to activate the output relay of the test battery box 100a. The charging / discharging power and various protection parameters of the charging / discharging unit 073 can then be set. The charging / discharging unit 073 is then started to verify the discharge function of the test battery box 100a. The discharged energy is then transferred to the test battery box 100b for recovery. During charging tests, power can be drawn from the test battery box 100b and connected to the charging interface 0711 on the first bracket 071 via the charging gun of the charging / discharging unit. The energy in the test battery box 100b is then transferred to the battery box under test for charging function verification.

[0095] It should be noted that the charging and discharging machine 073 has two charging guns: a power-on gun and a power-off gun. The charging and discharging machine 073 can automatically switch between the types of charging guns, meaning that at least some of the charging guns can be used as both power-on and power-off guns, without the need for frequent disassembly and reassembly of the charging guns.

[0096] It should be noted that the structure and principle of the charging and discharging integrated machine 073 have long been publicly available technology. This application does not improve the structure and principle of the charging and discharging integrated machine 073, and can directly adopt the products already on the market.

[0097] In some possible implementations, the first bracket 071 has an electrical connector e in its middle, which is electrically connected to the charging interface 0711 and the discharging interface 0712, respectively. When the test battery box 100a is seated on the first bracket 071, the electrical connector e is electrically connected to the test battery box 100a. The electrical connector e may include a charging connector and a discharging connector; the charging connector is connected to the charging interface 0711, and the discharging connector is connected to the discharging interface 0712.

[0098] In some possible implementations, the charging interface 0711 and the discharging interface 0712 are located on opposite sides of the first bracket 071. This facilitates wiring between the interfaces and the electrical connector e, does not interfere with the placement of the test battery box 100a, and makes full use of space.

[0099] In some possible implementations, at least two charging ports 0711 are provided on one side of the first bracket 071, and at least two discharging ports 0712 are provided on the other side of the first bracket 071. By providing two charging ports 0711 and two discharging ports 0712, the charging efficiency and discharging efficiency are improved.

[0100] In some possible implementations, the first support 071 includes an upper frame, a lower frame, and multiple columns. The upper and lower frames are spaced apart, and the columns are located between the upper and lower frames, connecting the upper and lower frames respectively. The battery positioning seat b, charging interface 0711, and discharging interface 0712 are all located on the upper frame. The lower frame can be stably supported on the ground. The design of the columns increases the height of the upper frame, facilitating the insertion and removal of the charging gun.

[0101] In some possible implementations, the first support 071 is also provided with a plurality of battery guide seats a, and the battery guide seats a are provided with inclined guide surfaces. As the test battery box 100a gradually approaches the first support 071 from top to bottom, it can contact the inclined guide surfaces, and the inclined guide surfaces guide the test battery box 100a to sit on the first support 071.

[0102] In some possible implementations, the second bracket 072 includes at least two bracket bodies 0721, which are spaced apart and arranged in parallel. Each bracket body 0721 is provided with an electrical connector e, a battery positioning seat b, and a battery guide seat a. Each bracket body 0721 can be equipped with a test-fit battery box 100b.

[0103] In this embodiment, the second bracket 072 is provided with two bracket bodies 0721, which can simultaneously hold two test battery boxes 100b, increasing the overall power capacity. The two test battery boxes 100b can be used in conjunction with one test battery box 100a for charge-discharge testing. Alternatively, the two test battery boxes 100b can be used separately with the two test battery boxes 100a for testing, improving testing efficiency.

[0104] In some possible implementations, the second support 072 includes a plurality of connecting beams 0722, each of which is located between two adjacent support bodies 0721 and is connected at both ends to the two adjacent support bodies 0721. The connecting beams 0722 connect the two support bodies 0721 to form a single unit.

[0105] In some possible implementations, the battery testing station 07 includes a housing 074, within which multiple power connectors are disposed. Each power connector is electrically connected to the test battery box 100b and is used to connect to the charging / discharging gun of the integrated charging / discharging machine 073. The power connector includes a charging interface and a discharging interface. The housing 074 integrates the charging and discharging interfaces of two test battery boxes 100b in the same location, facilitating connection to the charging / discharging gun.

[0106] The battery test station 07 may also include a charger for recharging the test battery box 100b when the total power is reduced due to multiple power switching during multiple test cycles, so that the test battery box 100b can continue to effectively cooperate with the test battery box 100a for charge and discharge tests.

[0107] This application also provides a battery box assembly system, including: a battery box production line and the aforementioned battery testing station 07. The battery box production line includes a guide rail 02 and several assembly mechanisms, each of which is arranged sequentially along the length of the guide rail 02. The battery testing station 07 is located at the end of the guide rail 02.

[0108] Example 4

[0109] like Figures 1 to 10 As shown, this application embodiment provides a battery box assembly system, including: a guide rail 02, several assembly mechanisms, a battery assembly auxiliary vehicle 01, a battery testing station 07, and process control equipment. Each of the assembly mechanisms is arranged sequentially along the length of the guide rail 02. The battery assembly auxiliary vehicle 01 has track wheels 013 that can roll along the guide rail 02. The battery testing station 07 is located at the end of the guide rail 02. The process control equipment includes multiple industrial computer platforms, each of which is arranged sequentially along the length of the guide rail 02. At least some of the industrial computer platforms have identification devices for identifying materials.

[0110] Identification marks, such as QR codes or other identification structures, can be set on each material and structural component. The identification device of the industrial control computer platform can be a barcode scanner, which can directly scan and identify key material components. The battery box assembly system of this application uses guide rail 02 as the core support throughout the entire production line. The orderly flow of the entire production line is realized through battery assembly auxiliary vehicle 01. Real-time collection of key node information is realized through process equipment, realizing visual monitoring and full-process traceability of the production process. This not only ensures information collaboration between processes, but also provides data support for quality control and problem investigation.

[0111] In some possible implementations, the battery pack assembly system includes a bottom frame loading area offset from the guide rail 02, and a battery assembly auxiliary vehicle 01 with landing wheels 012, which can drive off the guide rail 02 and proceed to the bottom frame loading area to load the bottom frame.

[0112] The bottom frame of the battery box requires pre-assembly of the high-voltage box and related cables, which is time-consuming. By setting the bottom frame loading area outside the guide rail 02, a larger and more abundant assembly space for the bottom frame can be provided outside the guide rail 02, accelerating the assembly efficiency of the bottom frame and avoiding the impact of the bottom frame assembly on the progress of the entire production line, thus improving the production cycle time. The battery assembly auxiliary vehicle 01 of this application has floor wheels 012 and track wheels 013, which support both movement on the guide rail 02 and movement on the ground, expanding the driving area of ​​the auxiliary vehicle 01, solving the problem of difficult transfer off the track, significantly shortening the process connection time, and greatly improving the production cycle time.

[0113] In some possible implementations, the battery pack assembly system includes a rail guide device disposed at one end of the guide rail 02 away from the battery test station 07. The rail guide device forms a rail channel that connects to the guide rail 02. When the battery assembly auxiliary vehicle 01 travels to the rail channel, the rail guide device restricts the travel direction of the battery assembly auxiliary vehicle 01, so that the track wheels 013 of the battery assembly auxiliary vehicle 01 are supported on the guide rail 02.

[0114] In some possible implementations, the battery pack assembly system includes a battery loading area and a top frame loading area, which are arranged sequentially along the length of the guide rail 02. Each assembly mechanism includes a battery assembly mechanism 051 and a top frame assembly mechanism 052, which are arranged sequentially along the extension direction of the guide rail 02. The battery assembly mechanism 051 is located in the battery loading area and is used to transfer the battery pack to the battery assembly auxiliary vehicle 01. The top frame loading area is located in the top frame loading area and is used to transfer the top frame 12 to the battery assembly auxiliary vehicle 01.

[0115] The battery pack is relatively heavy, so it needs to be loaded using the battery assembly mechanism 051 in the battery loading area to transfer the battery pack to the bottom frame 11. Then, operators or automated machinery assemble the battery pack and the bottom frame 11. The top frame 12 is also relatively heavy, so it needs to be transferred to the top of the battery pack using the top frame assembly mechanism 052. Then, operators or automated machinery fix the top frame 12 in place.

[0116] In some possible implementations, the process equipment includes a first industrial control computer platform 061, a second industrial control computer platform 062, a third industrial control computer platform 063, and a fourth industrial control computer platform 064. The first industrial control computer platform 061 is located on one side of the beginning of the guide rail 02 and is used to collect material information of each material in the bottom frame and the battery pack. The second industrial control computer platform 062 is located on one side of the guide rail 02 section of the top frame 12 of the battery box being assembled on the guide rail 02 and is used to collect material information of the top frame 12. The third industrial control computer platform 063 is located on the side of the guide rail 02 near the end and is used to collect material information of the auxiliary components. The fourth industrial control computer platform 064 is located on one side of the battery testing station 07 and is used to collect test information of the battery pack.

[0117] A high-voltage box is installed on the bottom frame 11. When the battery assembly auxiliary vehicle 01, carrying the bottom frame, travels to the beginning of the guide rail 02, the identification device of the first industrial control computer platform 061 can scan the high-voltage box, high-voltage lines (power supply lines), and low-voltage lines (communication lines) and bind the data. Subsequently, after the battery packs are assembled, the identification device of the first industrial control computer platform 061 identifies the battery packs and binds the data. The battery assembly auxiliary vehicle 01 travels to the top frame loading area. After the top frame 12 is assembled, the identification device of the second industrial control computer platform can scan each structural component in the top frame 12, such as obtaining data information of the water-cooled unit and related pipelines. Next, the battery assembly auxiliary vehicle 01 travels to a position close to the end of the guide rail 02. This position is the installation position for auxiliary components, including sealing plates, B-BOXs, and water-cooling pipes, etc. After the auxiliary components are installed, the identification device of the third industrial control computer platform can scan each auxiliary component to obtain its information. Finally, the battery assembly auxiliary vehicle 01 moves off the guide rail to the battery testing station 07 to conduct battery testing. After the test is completed, the test information can be input into the fourth industrial control computer platform 064, thereby completing the information binding of all structural components of the battery box.

[0122] After the bottom frame 11 is assembled, the battery assembly auxiliary vehicle 01 can drive to the guide rail 02 to assemble other structural components.

[0133] On the outside of guide rail 02, the water-cooled unit is first installed on the top frame 12. The assembly of the water-cooled unit and the top frame 12 requires considerable time. By pre-assembling the water-cooled unit and the top frame 12 on the outside of guide rail 02, the assembly of the top frame 12 and the water-cooled unit can avoid affecting the progress of the entire production line, thus improving production cycle time. The water-cooled unit and the top frame 12 can be hoisted onto the top frame 12 using a mobile truss hoisting device.

[0134] The assembly process involves transferring the top frame 12 to the top of the battery pack and assembling it using an assembly mechanism, including:

[0138] In this step, the industrial control computer platform collects information on the high-voltage box, high-voltage line, and low-voltage line.
