Description

Technical Field

[0001] The utility model belongs to the technical field of square lithium battery clamp assembly, and specifically relates to a square battery intelligent locking and torque pressure monitoring device. Background Art

[0002] The assembly and installation process of the square lithium battery fixture is as follows: the worker places the square lithium battery between the upper and lower clamping plates, and then passes the bolts and nuts through the upper and lower clamping plates. This completes the manual assembly of the fixture and pre-locks the nuts.

[0003] In traditional processes, after pre-locking the nuts, they are manually tightened and the flatness is checked after tightening. Manually tightening the nuts requires a lot of hand strength and high physical strength of the workers. Working for a long time may cause fatigue to the workers. Compared with mechanical automation, manual operation is slower and difficult to mass produce. It is also easy to cause a decrease in efficiency due to improper manual operation. Manual flatness inspection is limited by personal technical level and operational stability, and there may be errors, which will affect the performance of the battery fixture. Manual operation cannot ensure the consistency of the quality of the fixture for each assembly, which may cause quality fluctuations between product batches. When manually operating the nuts and checking the flatness, workers may face safety risks such as sharp edges and slipping. Manual tightening may cause inaccurate nut position, affecting the appearance of the fixture. Process data cannot be accurately recorded, which is not conducive to later tracking.

[0004] To overcome these defects, modern production lines usually use automated equipment to complete the assembly and testing of battery fixtures, thereby improving production efficiency, ensuring product quality, reducing labor intensity, and improving work safety. In view of this, we propose a square battery intelligent locking and torque pressure monitoring device. Utility Model Content

The prismatic battery is first manually placed on the fixture base plate of the lower frame. A QR code is then scanned and uploaded to the Manufacturing Execution System (MES), or the assembled fixture is removed from the lower frame. The fixture transfer mechanism then automatically transfers the fixture from the manual loading and unloading station to the nut locking station. The front-to-back centering push block mechanism adjusts the fixture's position. After the pressure plate mechanism presses the fixture into position, the nut locking mechanism automatically tightens the fixture's nuts.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The following is combined with Figure 1-11 To further explain this application,

[0040] The embodiment of the present application discloses a square battery intelligent locking and torque pressure monitoring device, comprising a lower frame 1 and an upper frame 2 located on the top of the lower frame 1, a manual loading and unloading position 13 is provided on the top of the lower frame 1 and on one side of the upper frame 2, a fixture transfer mechanism 3 for moving a manually assembled fixture for loading or unloading is provided on the top of the lower frame 1, a front and rear centering pushing block mechanism 4 for adjusting the square battery on the fixture transfer mechanism 3 forward and backward so that the square battery is located in the middle of the pressure plate, and a nut locking mechanism 5 for simultaneously locking the nut and controlling the torque or pressure, a pressure plate mechanism 6 for pressing the fixture to position it on the fixture transfer mechanism 3, and a flatness detection mechanism 7 located at a flatness testing station and used to test the flatness of the fixture;

[0041] The fixture is used to clamp square batteries. After the fixture is placed on the fixture transfer mechanism 3, it is transferred to the locking nut station through the fixture transfer mechanism 3. At the locking nut station, the square battery is adjusted to the center position and aligned with the middle of the pressure plate on the pressure plate mechanism 6 through the front and rear centering push block mechanism 4. After the fixture is pressed and positioned by the pressure plate mechanism 6, the nut locking mechanism 5 automatically locks the nut of the fixture. The locked fixture is transferred to the flatness test station under the action of the fixture transfer mechanism 3, and the flatness of the fixture is detected by the flatness detection mechanism 7.

[0042] The manual loading and unloading position 13 is used to manually place square batteries into the fixture of the upper frame 2, or to remove the assembled fixture from the lower frame 1. The fixture transfer mechanism 3 automatically transfers the fixture from the manual loading and unloading position 13 to the locking nut position. At the locking nut position, the front-to-back centering push block mechanism 4 adjusts the fixture to the front-to-back center position of the middle of the pressure plate to ensure that the fixture is accurately aligned in the pressure plate and the nut locking mechanism 5. The pressure plate mechanism 6 presses the fixture into position to ensure that the fixture does not move when the nut is locked. The nut locking mechanism 5 automatically locks the nut on the fixture. This mechanism can control the locking torque or pressure to ensure that the nut is locked to the specified accuracy. The flatness detection mechanism 7 is used to detect the flatness of the fixture after locking to ensure that the quality of the fixture meets the requirements.

[0043] The top plate of the upper frame 2 is provided with louver holes 8 and a three-color light 9, the front side of the upper frame 2 is provided with a door panel 10, and the side of the upper frame 2 and the side close to the manual loading and unloading position 13 are provided with a display screen 11 and a touch screen 12.

[0044] The louver holes 8 are used to prevent battery fires, release pressure within the device, and ensure that the internal components of the device will not overheat due to the heat generated by long-term operation. At the same time, they can also provide a certain shielding effect to protect the internal components from being contaminated or damaged by external debris.

[0045] The three-color light 9 is usually used to indicate the working status of the device. For example, red may represent stop or warning, yellow may represent attention or standby, and green may represent normal operation. Such a design allows the operator to quickly understand the status of the device and make corresponding measures in time.

[0046] The presence of the door panel 10 can protect the operator from being hurt by the internal moving parts, and can also prevent external debris from entering the interior of the equipment and affecting the normal operation of the equipment. When maintaining and repairing, opening the door panel 10 can easily access the internal components.

[0047] Display screen 11 and touch screen 12 provide intuitive operation and information feedback for operators. Touch screen 12 allows operators to directly control the device, simplifying the process and improving efficiency. Display screen 11 also displays device operating parameters, fault diagnosis information, and other relevant information, helping operators better control and manage the device.

[0048] The fixture transfer mechanism 3 includes a ball screw linear module 301 fixed on the top of the lower frame 1, and a fixture carrier 303 fixed on the movable slide of the ball screw linear module 301 and slidably connected to the linear guide rail 302 on the top of the lower frame 1.

[0049] The fixture carrier plate 303 includes a fixed base plate 304 fixed on the movable slide, a fixture fixing plate 305 fixed on the top of the fixed base plate 304 , and limit blocks 306 fixed on four sides of the fixture fixing plate 305 .

[0050] The ball screw linear module 301 is a precision transmission assembly consisting of a screw and a drive motor. The motor rotates the screw, which in turn moves the movable slide, attached to the screw, along the linear guide 302, achieving precise positioning of the fixture. The fixture carrier 303 is fixed to the movable slide and slides along the linear guide 302 to the guide rail on the top of the lower frame 1. This allows the fixture carrier 303 to move along the guide rail, transferring the fixture from one location to another.

[0051] The fixture carrier 303 is composed of a fixed base plate 304, a fixture fixing plate 305, and a stop block 306. The fixed base plate 304 provides stable support, the fixture fixing plate 305 secures the fixture, and the stop block 306 ensures the fixture's positional accuracy during movement, preventing it from moving beyond a set range.

[0052] The front and rear centered pushing block mechanism 4 includes two sets of lifting frames 402 that are movable through the lower frame 1 and fixedly connected to the two limit push plates 401 above the lower frame 1, two sets of servo linear modules 403 fixed on the inner side of the lower frame 1, and moving plates 404 that are respectively fixedly connected to the moving seats on the two sets of servo linear modules 403. A servo screw module 405 is installed on the moving plate 404 and drives the lifting frame 402 and the limit push plate 401 to move up and down, and a limit guide rail 406 is fixed on the inner side of the lower frame 1 and cooperates with the two moving plates 404 to guide the sliding.

[0053] The lifting frame 402 is movable throughout the lower frame 1 and is fixedly connected to the upper limit push plate 401, which enables the limit push plate 401 to achieve lifting and lowering motion. Two sets of servo linear modules 403 fixed on the inner side of the lower frame 1 provide power to drive the movable seat and movable plate 404 to perform linear motion. The servo screw module 405 installed on the movable plate 404 drives the lifting frame 402 and the limit push plate 401 to move up and down, and the limit push plate 401 can move left and right, achieving precise control. The limit guide rail 406 cooperates with the movable plate 404 to ensure the linear motion trajectory of the movable plate 404 and ensure the precise positioning of the fixture.

[0054] The high-precision positioning of the fixture is achieved through the cooperation of the servo linear module 403 and the servo screw module 405, and the front and rear centering push block mechanism 4 places the battery in the middle of the pressure plate.

[0055] The pressure plate mechanism 6 includes a servo electric cylinder 601 fixed on the inner side of the lower frame 1, a pressure sensor 602 fixed on the end of the output shaft of the servo electric cylinder 601, and a lifting assembly 603 and a pressure plate assembly 604 driven by the servo electric cylinder 601 above the pressure sensor 602. The guide rod 605 at the bottom of the pressure plate assembly 604 moves along the linear bearing 606 embedded in the lower frame 1.

[0056] A servo cylinder 601, mounted on the inside of the lower frame 1, provides power to drive the lifting and lowering motion of the pressure plate assembly 604. A pressure sensor 602, mounted on the output shaft of the servo cylinder 601, monitors the pressure of the pressure plate in real time, ensuring the stability of the fixture. The servo cylinder 601 drives the lifting and positioning of the pressure plate. A guide rod 605, which moves along a linear bearing 606 on the lower frame 1, ensures the accurate movement of the pressure plate assembly 604.

[0057] Precise control of the servo cylinder 601 and pressure sensor 602 enables precise clamping of the fixture. Integration with automated control systems allows precise pressure control and improves production efficiency. Pressure sensor 602 monitors the pressure of the pressure plate in real time to ensure fixture stability. This system can accommodate fixtures of varying sizes and types, offering excellent flexibility.

[0058] The nut locking mechanism 5 is provided with eight sets of tightening mechanisms 501, and the tightening mechanisms 501 are symmetrically installed on the bracket 502 on both sides. The tightening mechanism 501 includes a vertical servo module 503 installed on the bracket 502, a lifting platform 504 fixed on the lifting seat of the vertical servo module 503, a locking servo motor 506 fixed on the lifting platform 504 and used in conjunction with the torque sensor 505, a buffer tightening rod 507 rotatably arranged on the lifting platform 504, a synchronous wheel A508 arranged on the buffer tightening rod 507, a synchronous wheel B509 rotatably arranged at the end of the output shaft of the locking servo motor 506, a synchronous wheel B509 rotatably arranged on the lifting platform 504, a synchronous belt driven by the synchronous wheel A508, the synchronous wheel B509, and the synchronous wheel C510, and a standard sleeve 511 that is detachable and replaceable and is arranged at the bottom end of the buffer tightening rod 507.

[0059] The lower frame 1 is provided with a longitudinal linear module 512 that drives the bracket 502 to translate. The longitudinal linear module 512 drives the bracket 502 to slide on the adjustment shaft 513 at the top of the lower frame 1, and the bracket 502 is locked and fixed on the adjustment shaft 513 by a locking bolt.

[0060] Each tightening mechanism 501 comprises a vertical servo module 503, a lifting platform 504, a locking servo motor 506, and a buffer tightening rod 507. Synchronous motion of the buffer tightening rod 507 is achieved through the coordination of a synchronous pulley and a synchronous belt. A torque sensor 505, working in conjunction with the locking servo motor 506, monitors and controls tightening torque in real time, ensuring the nut is tightened to the desired value. The removable and replaceable standard sleeve 511 facilitates the replacement and maintenance of nuts of varying specifications. A longitudinal linear module 512 drives the bracket 502 in translation, allowing it to slide along a guided adjustment shaft 513 at the top of the lower frame 1, facilitating adjustment and positioning.

[0061] The tightening mechanism 501 in the nut locking mechanism 5 is divided into 8 groups. The locking height is controlled by the vertical servo module 503. The locking servo with torque sensor 505 performs real-time torque monitoring and locking of the nut. The maximum torque is 10NM. The standard sleeve 511 can be quickly replaced. The eight groups of tightening mechanisms 501 provide high torque output to ensure that the nut is firmly locked. The synchronous transmission ensures the synchronous movement of each tightening mechanism 501 and improves the consistency of assembly. The torque sensor 505 realizes precise torque control and ensures the quality of nut locking. The detachable and replaceable standard sleeve 511 reduces the difficulty and cost of maintenance. Through the adjustment of the longitudinal linear module 512, it can adapt to the installation requirements of different fixtures.

[0062] like Figure 7 As shown, the eight sets of tightening mechanisms 501 are divided into two sets, and the two sets move synchronously in the Y direction with the center of the fixture as the reference. A single tightening mechanism 501 can move in the X and Z directions. The minimum spacing of the locking heads in the X direction is Xmin = 40 mm, the maximum spacing of the locking heads in the X direction is Xmax = 250 mm, the minimum distance of the locking heads in the Y direction is Ymin = 85 mm, and the maximum distance of the locking heads in the Y direction is Ymax = 600 mm.

[0063] The flatness detection mechanism 7 includes a transverse linear module 702 fixed on a top support seat 701 of the lower frame 1 and a displacement sensor 703 fixed on a moving seat of the transverse linear module 702 .

[0064] The displacement sensor 703 can achieve high-precision flatness detection and be integrated with the automated control system to achieve precise control and monitoring of the fixture flatness. By detecting the fixture flatness in real time, the consistency and reliability of assembly quality can be ensured.

[0065] This square battery intelligent locking and torque pressure monitoring equipment is an automated equipment that can work continuously, improving production speed and efficiency. The automated equipment can accurately position and lock the fixture, ensuring the assembly accuracy of the product, reducing the need for manual operation, and reducing the cost and potential errors caused by manual operation. Workers do not need to directly contact and operate dangerous machines, which improves workplace safety. The automated equipment ensures the consistency of each operation and improves the consistency of product quality. Through this automated square battery intelligent locking and torque pressure monitoring equipment, the production process becomes more efficient, accurate and reliable, while also saving human resources for the factory and improving the level of safe production.
