Description

Technical Field

[0001] This invention relates to the field of battery assembly technology, specifically to a battery bus terminal assembly device and method. Background Technology

[0002] In the battery production and assembly process, bus terminals are key components for current conduction and circuit connection between individual battery cells. The reliability of their connection directly determines the overall performance and safety stability of the battery pack. To meet the requirements of optimized internal battery structure layout, improved space utilization, and rational current path design, some bus terminals are designed with screw holes for fixed connections on the side of the terminal to adapt to the compact assembly requirements of specific battery models.

[0003] However, the screw-driving equipment widely used in the industry currently operates primarily in a vertical "up-down" manner. The screwdriver bits can only feed and tighten vertically, making it unsuitable for the horizontal screw-driving requirements of side-mounted screw holes. To address this mismatch between the equipment and the workpiece structure, current production processes typically employ a simple fixture to rotate the battery at a certain angle, aligning the side screw holes of the busbar terminals vertically upwards, thus meeting the screw-driving machine's directional requirements.

[0004] However, due to the lack of specialized equipment for this type of flipping and positioning, it is difficult to obtain stable and accurate positioning support for the flipped battery and bus terminals. Specifically, this manifests in two ways: firstly, the battery is prone to displacement or wobbling due to gravity when tilted, making it difficult to guarantee the coaxiality of the screw hole and screwdriver bit; secondly, the bus terminals themselves have limited structural strength, and without specialized clamps for fixation, the axial force generated during screw tightening can easily cause deformation or displacement of the terminals. These instabilities directly lead to quality defects such as stripped threads, inconsistent screw tightening depth, and damaged screw holes during screw tightening, not only reducing the production pass rate and increasing rework costs, but also potentially leaving safety hazards during battery pack use due to unreliable connections, severely restricting production efficiency and product quality improvement in the battery assembly process. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the difficulty of screw assembly of batteries and bus terminals in the prior art, and to provide a battery bus terminal assembly device and method.

[0010] In one embodiment of the present invention, the limiting component further includes an extension frame and a screw hole calibration plate. The extension frame is disposed on the slide plate and surrounds the abutment block. The screw hole calibration plate is connected to the extension frame and has calibration holes thereon. The screw gun can pass through the calibration holes to the screw holes of the busbar terminals to be assembled.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Example 1:

[0031] See Figure 1 As shown, this embodiment provides a battery bus terminal assembly device, which includes:

[0032] The fixing mechanism 100 includes a bearing component 120, which includes a first support frame 121 and a bearing platform 122. The support surface of the first support frame 121 is inclined, and the bearing platform 122 moves against the support surface. The battery to be assembled is supported on the bearing platform 122 and is set against the support surface so that the screw holes of the bus terminal to be assembled are vertically set.

[0033] The material transfer mechanism 200 includes at least one flipping and transferring assembly 230 and an assembly assembly 240. The flipping and transferring assembly 230 includes a first lifting frame 231, a rotary driver 232, a flipping frame 235, and at least two material transfer clamps 237. The first lifting frame 231 can move closer to / away from the support assembly 120. The rotary driver 232 is disposed on the first lifting frame 231, and its working end is connected to the flipping frame 235 to drive the flipping frame 235 to rotate around the rotation center line 1001. The material transfer clamps 237 are connected to the flipping frame 235 and can open and close relative to each other to clamp the battery. The assembly assembly 240 includes a second lifting frame 241 and a screw gun 242. The screw gun 242 is disposed on the second lifting frame 241 and moves closer to / away from the support assembly 120 through the second lifting frame 241.

[0034] It should be noted that, for ease of description, in this embodiment, the length direction of the battery bus terminal assembly equipment is defined as the first direction X, the width direction of the battery bus terminal assembly equipment is defined as the second direction Y, and the height direction of the battery bus terminal assembly equipment is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0035] The battery busbar terminal assembly equipment provided in this embodiment is specifically designed to solve industry pain points such as the mismatch between the side screw holes of the busbar terminals and the working direction of the screw-driving equipment, and unstable workpiece positioning during the current battery assembly process. In the specific operation process, the flipping and transferring assembly 230 first flips the horizontally conveyed battery and busbar terminal to be assembled synchronously as a whole. Then, the fixing mechanism 100 holds the battery and busbar terminal to be assembled and can stably maintain them in an inclined state to ensure that the screw holes of the busbar terminals are vertically set. Then, the assembly assembly assembly 240 fixes them with screws, thereby completing the assembly. Throughout the above process, the fixing mechanism 100 always maintains stable support for the battery and busbar terminals until the screws are fully tightened in place, thus completing the entire busbar terminal assembly process.

[0036] In this embodiment, the fixing mechanism 100 is the core support carrier of the entire assembly equipment. Its core function is to provide precise and stable tilt positioning for the battery to be assembled and the busbar terminal, ensuring that the screw holes of the busbar terminal always remain vertical, thus creating suitable conditions for subsequent screw fastening. Specifically, the tilt angle of the first support frame 121 needs to precisely match the angle between the side opening position of the screw hole of the busbar terminal and the vertical direction. It can typically be adjusted between 30° and 60° according to actual usage requirements. Through a preset tilt support surface, it directly provides a reference for tilting the battery. When the battery is in contact with the support surface, the screw hole of the busbar terminal, which originally faced the side, can naturally turn vertically upwards. Structurally, this solves the core problem of the mismatch between the screw hole direction and the working direction of the screw gun 242, meeting the straight-up-down fastening requirements of the screw gun 242 without additional adjustments.

[0037] The support platform 122 moves along the inclined support surface of the first support frame 121. Its support position can be flexibly adjusted via the lifting driver 123 according to the model and specifications of the battery to be assembled, ensuring that batteries of different sizes can accurately fit the support surface and preventing screw hole misalignment due to battery size differences. On the other hand, the support platform 122 provides direct support for the battery, forming a double support with the support surface, preventing the battery from sliding along the support surface due to gravity or vibration during screwing, further enhancing the stability of the inclined state. Specifically, the working end of the lifting driver 123 is connected to the support platform 122 to drive the support platform 122 to move up and down. It is preferably a linear cylinder; the specific type of lifting driver 123 is not limited in this invention.

[0038] The carrier component 120 in this embodiment also includes a first material detector 124, which is disposed on the top of the first support frame 121. The first material detector 124 can accurately identify and judge the status of the battery on the carrier platform 122. It can monitor in real time whether the battery is in place, whether the battery posture is compliant, and other information to perform safety confirmation before assembly, thereby improving assembly efficiency and safety.

[0039] Further, see Figures 2 to 4As shown, the supporting assembly 120 in this embodiment further includes a side-pressure module 126 and at least two side-pressure plates 125. The side-pressure module 126 is connected to the first support frame 121 and extends along the width direction of the first support frame 121. The side-pressure plates 125 are slidably connected to the side-pressure module 126 to move relatively closer to / away from it. Specifically, the side-pressure module 126 is used to fix and hold the battery in a tilted state. The side-pressure module 126 is connected to the first support frame 121 and extends along the width direction of the first support frame 121, thereby enabling it to accurately cover the lateral area of ​​the battery on the tilted support surface, thus ensuring that the side-pressure plates 125 can apply clamping force from both sides of batteries of different specifications. Based on this, compared with the traditional fixing method that only relies on the friction of the support platform 122, the lateral clamping force forms a three-dimensional constraint with the support surface and the support platform 122, which significantly improves the positioning accuracy of the battery in the tilted state, provides a guarantee for the accuracy of subsequent screw fastening, and further reduces quality problems such as stripping and inconsistent screw fastening depth caused by battery offset.

[0040] In this embodiment, the fixing mechanism 100 includes a limiting component 130, which includes a second support frame 132, a sliding plate 133, a limiting driver 134, and an abutment block 137. The second support frame 132 is disposed on one side of the support surface and has an adjustment module 131 extending toward the first support frame 121. The working end of the limiting driver 134 is connected to the sliding plate 133 to drive the sliding plate 133 to slide along the adjustment module 131. The abutment block 137 is disposed on the sliding plate 133 and has an abutment surface parallel to the support surface on the side facing the first support frame 121. The limiting component 130, through the coordinated cooperation of the second support frame 132, the sliding plate 133, the limiting driver 134 and the abutment block 137, further fills the end positioning deviation problem that may exist if only the bearing platform 122 supports and the side pressure module 126 clamps it laterally. It provides lateral protection for the all-round stability of the battery in the tilted state and ensures that the bus terminal screw hole is always in the preset vertical assembly position.

[0041] Specifically, the second support frame 132 provides a stable guide path for the sliding plate 133, ensuring that the limiting force of the subsequent abutment block 137 on the battery can be precisely applied to the side end of the battery. This prevents damage to the bus terminals or obstruction of screw holes due to the limiting action, thus ensuring the smoothness of the assembly process from a structural layout perspective. The sliding plate 133 can convert the power of the limit actuator 134 into linear motion along the adjustment module 131, thereby driving the abutment block 137 to move closer to or away from the battery. The limit actuator 134, as the power source of the limit assembly 130, provides driving force for the sliding plate 133 through a direct connection between its working end and the sliding plate 133.

[0042] When the flipping and transferring assembly 230 places the battery on the support platform 122, and the first material detector 124 confirms that the battery is initially in place, the limit driver 134 drives the slide plate 133 to move along the adjustment module 131 toward the side of the battery until the abutment block 137 contacts the side of the battery and applies a preset limiting force. During the screwing process, the limit driver 134 maintains a stable driving force, so that the abutment block 137 always forms a lateral constraint on the battery. After assembly, the limit driver 134 reverses the drive of the slide plate 133, moving the abutment block 137 away from the battery, making room for the flipping and transferring assembly 230 to remove the finished battery. Furthermore, the abutment block 137 has an abutment surface parallel to the support surface on the side facing the first support frame 121, thereby ensuring that when the abutment block 137 contacts the side of the battery, the abutment surface can completely fit with the side surface of the battery, avoiding the battery tilting or shifting due to uneven force, further calibrating the battery's posture, and ensuring that the vertical state of the bus terminal screw holes does not change. In different implementations, a flexible buffer layer can be added to the contact surface to avoid scratching damage to the battery casing caused by rigid contact, improve positioning stability, and effectively suppress the slight displacement of the battery caused by vibration during screwing.

[0043] Furthermore, the limiting component 130 also includes an extension frame 135 and a screw hole calibration plate 136. The extension frame 135 is disposed on the slide plate 133 and surrounds the abutment block 137. The screw hole calibration plate 136 is connected to the extension frame 135 and has a calibration hole 1361 thereon. The screw gun 242 can pass through the calibration hole 1361 to the screw hole of the bus terminal to be assembled. The extension frame 135 is fixedly connected to the slide plate 133, allowing it to move synchronously with the slide plate 133. When the limit driver 134 drives the slide plate 133 to move the abutment block 137 to the side of the battery to complete the limit, the extension frame 135 will also move precisely with the slide plate 133 to the preset position corresponding to the screw hole of the bus terminal, ensuring that the calibration hole 1361 of the subsequent screw hole calibration plate 136 can be initially aligned with the screw hole. The calibration hole 1361 on the calibration plate has a diameter and position that match the screw hole of the bus terminal to be assembled. When the screwdriver 242 performs the screw-driving action, it must first pass through the calibration hole 1361 and then align with the screw hole. The calibration hole 1361 is equivalent to providing a front guide channel for the screwdriver bit of the screwdriver 242, thereby limiting the radial displacement of the bit and ensuring that the bit accurately enters the screw hole of the bus terminal, greatly reducing the risk of stripping the thread or the bit damaging the screw hole.

[0044] In addition, the fixing mechanism 100 also includes a mounting plate 110, which extends along the first direction X. The bearing component 120 and the limiting component 130 are both disposed on the mounting plate 110. The material transfer mechanism 200 also includes a fixing frame 210 and a moving plate 220. The fixing frame 210 is disposed on one side of the mounting plate 110 and has a horizontal module 211 extending along the first direction X. The moving plate 220 is slidably connected to the horizontal module 211. The flipping and transferring component 230 and the assembly component 240 are respectively disposed on the moving plate 220, thereby constructing a structural layout in which the fixing mechanism 100 and the medical assembly mechanism can work in a highly coordinated manner.

[0045] See Figures 5 to 7 As shown, in this embodiment, the flipping and transferring assembly 230 is used to flip the batteries pre-installed with bus terminals on the horizontal transmission line and accurately transfer them to the support platform 122 of the fixing mechanism 100, realizing automated connection from horizontal loading to tilt positioning. The first lifting frame 231 serves as the lifting adjustment unit of the flipping and transferring assembly 230, solving the height adaptation problem during battery gripping and placement by moving closer to / away from the support assembly 120. During the gripping stage, the first lifting frame 231 lowers the flipping frame 235 and the transfer clamp 237 below to the battery height on the horizontal transmission line, facilitating the transfer clamp 237 to hold the battery. During the transfer stage, the first lifting frame 231 rises and moves above the support assembly 120, then lowers to smoothly place the flipped battery on the support platform 122, preventing collisions between the battery and other structures during transfer and ensuring transport safety. The rotary actuator 232 serves as the power source for the flipping and transferring assembly 230. Its working end is connected to the flipping frame 235, which can drive the flipping frame 235 to rotate around a preset rotation center line 1001. After gripping the battery, the rotary actuator 232 precisely controls the flipping angle to synchronously drive the battery and busbar terminals to complete the overall flipping, so that the screw holes of the busbar terminals can be aligned vertically in one go, improving positioning accuracy. One end of the flipping frame 235 is connected to the working end of the rotary actuator 232, and the other end is fixed to the transfer clamp 237, so as to drive the transfer clamp 237 and the battery and busbar terminals to be assembled to flip and move synchronously. At least two transfer clamps 237 clamp the battery from both sides by relatively opening and closing movement.

[0046] Furthermore, the material transfer mechanism 200 includes two flipping and transferring components 230, which are arranged along the first direction X on the moving plate 220 to respectively load components to be assembled and unload assembled components. The assembly component 240 is disposed between the two flipping and transferring components 230. The moving plate 220 is provided with two first lifting modules 221 and a second lifting module 222 extending along its height direction. The two flipping and transferring components 230 are slidably connected to the first lifting modules 221, and the assembly component 240 is slidably connected to the second lifting module 222. Thus, through the layout of the double flipping and transferring components 230 and the centrally located assembly component 240, an automated workflow integrating loading, assembly, and unloading is constructed. This not only breaks through the efficiency bottleneck of traditional single-station assembly but also, relying on a precise lifting drive structure, ensures that the actions of each component are coordinated and do not interfere with each other, providing core support for the high efficiency and stability of battery bus terminal assembly.

[0047] Two flipping and transferring components 230 are sequentially arranged on the moving plate 220 along the first direction X, forming a symmetrical workstation layout of front loading and rear unloading: one flipping and transferring component 230 is specifically responsible for loading components to be assembled, that is, grabbing the battery to be screwed from the horizontal conveyor line, adjusting it to an inclined state through a flipping action, and then accurately transferring it to the support platform 122 of the fixing mechanism 100; the other flipping and transferring component 230 is used for unloading components after assembly. After the assembly component 240 completes the screw fixing, it grabs the assembled battery from the support platform 122, flips it back to a horizontal state, and transfers it to the downstream conveyor line. This dual-component division of labor design allows the loading and unloading actions to be performed simultaneously, greatly shortening the single assembly cycle.

[0048] Furthermore, the two first lifting modules 221 on the movable plate 220 correspond to the two flipping and transferring components 230 respectively. The flipping and transferring components 230 are connected to the first lifting modules 221 by a sliding connection and can be flexibly raised and lowered along the height direction of the module. The second lifting module 222 is specially adapted to the assembly component 240. It drives the assembly component 240 to rise and fall along the height direction to precisely control the feed depth of the screwdriver 242: when screwing, the screwdriver 242 is driven down to the position of the calibration hole 1361 to ensure that the bit is accurately inserted into the calibration hole 1361 and screwed into the screw hole; after the screw is tightened, the screwdriver 242 is driven up to reset, making room for the unloading action of the flipping and transferring components 230.

[0049] In this embodiment, the tilting frame 235 adopts a built-in layout design, and is entirely set inside the first lifting frame 231. This structural layout not only saves the overall space occupied by the equipment, but also protects the tilting frame 235 through the frame structure of the first lifting frame 231, preventing external debris from interfering with the tilting action. Both ends of the tilting frame 235 are rotatably connected to the first lifting frame 231 via rotating shafts. This connection method provides stable rotational support for the tilting frame 235, allowing it to rotate flexibly around the axis of the rotating shaft as the rotation center line 1001, ensuring the smoothness of the tilting process and the accuracy of angle control.

[0050] Furthermore, the working end of the rotary actuator 232 is connected to the edge of the flipping frame 235 via a rotating connector. This connection design utilizes the lever principle, enabling efficient rotation of the flipping frame 235 with a relatively small driving force. When the rotary actuator 232 is working, its output end applies a pushing force to one side of the flipping frame 235 in the vertical direction. Under this force, the flipping frame 235 rotates around the rotation center line 1001 formed by the two rotating shafts, thereby driving the battery and busbar terminals clamped on the transfer clamp 237 to complete the flipping action from a horizontal state to a preset tilted state. This pushing drive method not only precisely controls the flipping angle, ensuring that the screw holes of the busbar terminals are vertically aligned with the requirements of each flip, but also flexibly adapts to the flipping needs of batteries of different weights by adjusting the magnitude and stroke of the driving force, ensuring the stability and reliability of the flipping process.

[0051] Specifically, in the flipping and transferring assembly 230 of this embodiment, the connecting disk 233, the sensor 234 and the sensing plate 236 together constitute a flipping angle detection and precision control unit. Through the combination of mechanical structure and sensing technology, real-time monitoring and closed-loop control of the rotation angle of the flipping frame 235 are realized to ensure that the battery can accurately reach the preset tilt posture after flipping.

[0052] The connecting plate 233 serves as the mounting carrier for the sensor 234. Through its fixed connection with the first lifting frame 231, it forms a relatively static reference structure. The mounting slot on the connecting plate 233 is parallel to the flipping path of the flipping frame 235, ensuring that the sensor 234 can stably align with the movement trajectory of the sensing element 236. It also provides adjustment space for adapting the flipping angle to different battery models, enhancing the structure's versatility. The sensor 234, installed in the mounting slot of the connecting plate 233, acts as a signal generator for angle detection. Its core function is to generate an electrical signal change through the intervention of the sensing element 236. When the sensing element 236 rotates with the flipping frame 235 and enters the detection area of ​​the sensor 234, the sensor 234 triggers a signal. This signal is transmitted in real-time to the equipment control system, serving as the basis for determining whether the flipping angle has reached the preset position.

[0053] In this embodiment, the flipping and transferring assembly 230 further includes an opening and closing driver 238 and a second material detector 239. The opening and closing driver 238 is connected to the bottom of the flipping frame 235, and the transferring clamp 237 is slidably connected to the two working ends of the opening and closing driver 238. The second material detector 239 is disposed on one side of the transferring clamp 237 and faces the clamping space of the transferring clamp 237. The placement of the opening and closing driver 238 and the second material detector 239 in the flipping and transferring assembly 230 further improves the power control and status monitoring system for battery clamping. Through the collaboration of the two and the transferring clamp 237, reliable clamping and safe transfer of the battery are ensured throughout the entire process of gripping, flipping, and transferring. The second material detector 239, disposed on one side of the transferring clamp 237 and facing the clamping space, can determine whether a battery exists in the clamping space, avoiding empty clamping action, and can also confirm whether the battery is accurately clamped, preventing battery shaking during flipping due to unstable clamping.

[0054] In this embodiment, the second lifting frame 241 in the assembly assembly 240 is used to control the screw gun 242 to move vertically closer to / away from the battery on the support assembly 120. This allows for a preset feed stroke based on the screw length and hole depth, ensuring the screw gun 242 accurately inserts into the screw hole and reaches the preset locking depth, preventing damage to the screw hole due to overfeeding or insufficient feed resulting in a loose screw. The screw gun 242 is used to directly lock the screw.

[0055] This embodiment also includes a control system. During actual production and processing, operators can adjust the above structure in real time through the control system, thereby improving the flexibility of the equipment. Parameters can also be preset through the control system, thereby improving the automation level of the equipment.

[0056] Example 2:

[0057] This embodiment provides a battery bus terminal assembly method, which uses the battery bus terminal assembly equipment described in Embodiment 1 to assemble the battery to the bus terminal, and includes:

[0058] Step S1: Transfer the connected battery and terminals to the working range of the transfer assembly 230;

[0059] Step S2: After the horizontally placed battery is clamped by the flipping and transferring assembly 230, it is flipped until the screw holes on the terminals become vertical.

[0060] Step S3: Move the terminals of the flipped battery into the carrier assembly 120;

[0061] Step S4: Assemble the battery and terminals by tightening screws using assembly component 240;

[0062] Step S5: The assembled battery and terminals are removed from the carrier assembly 120 by the flipping and transferring assembly 230, and then the assembly is readjusted to a horizontal state before being unloaded.

[0063] In summary, compared to traditional assembly technologies, this invention, through the coordinated operation of the flipping and transferring component 230, the fixing mechanism 100, and the assembly component 240, achieves a high degree of compatibility between the screw holes and the assembly component 240, fundamentally solving the compatibility problem between straight-up-down screw-driving equipment and side screw holes. Furthermore, the fully automated flipping, positioning, and assembly process significantly shortens the single assembly cycle, substantially improves the assembly quality and precision of the battery bus terminal, effectively meeting the demands of large-scale battery production for efficient, high-precision, and highly stable assembly processes, and providing reliable assurance for the safety performance and service life of the battery pack.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
