Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery shaping equipment, in particular to a double-module pressing and shaping table. BACKGROUND

[0002] In the current new energy battery module and PACK production and manufacturing field, the pressing and shaping of the module is a crucial process. This process aims to combine multiple cells in an orderly and compact manner into a unified module module. Its core function is to ensure that the glue area between the cells inside the module is stable and uniform by applying external pressure, and to ensure that the size of all output modules is strictly consistent. A successful pressing and shaping process is directly related to the tightness of the module inside, and is the basic physical guarantee for ultimately improving the energy density, safety performance and endurance of the battery PACK package. At present, various pressing and shaping equipment is commonly used in the industry to perform this process.

[0003] However, the existing module pressing and shaping equipment and technology still has many shortcomings. First, many devices have poor compatibility and are difficult to flexibly adapt to the production needs of single, double or multi-column modules of different specifications, resulting in complex and time-consuming adjustments when switching products on the production line. Second, the degree of automation and intelligence of the device is limited, and there are bottlenecks in pressure control accuracy and positioning accuracy, which affects the further improvement of the consistency of the module size, and still requires more manual intervention in the entire process, such as manual labeling, which not only low efficiency, but also risks human error. In addition, the existing equipment often lacks full-process data tracing capability, and processing information cannot be automatically uploaded to the management system, which is not conducive to product quality monitoring and process optimization. These shortcomings together result in the existing technology being unable to meet the growing demand for high-performance battery PACK in the market in terms of production efficiency, stability, maintenance cost and product consistency.

[0069] New energy batteries have the advantages of high efficiency, cleanliness, safety, and reliability, and have become the focus of current energy development. With the rapid development of the new energy electric vehicle industry, people's demand for the safety and endurance of new energy vehicles has become the most core demand, and continuously improving the safety performance and energy density of PACK packages not only puts higher requirements on the production process of batteries, but also puts higher challenges on the production process of modules and PACK.

[0071] In summary, there is an urgent need for a module shaping and pressing equipment that is environmentally friendly, energy efficient, stable, and low maintenance cost.

[0072] The technical solutions provided by the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0075] The conveying system 2 comprises a tray 21, a conveying line 22, a blocking mechanism 23, a spring pressing mechanism 24 and a trapezoidal screw mechanism installed on the side of the tray 21, and the tray 21 is placed on the conveying line 22; the blocking mechanism 23 is arranged in the conveying direction of the conveying line 22 and is used for limiting the tray 21 to a preset station; the spring pressing mechanism 24 is arranged in the width direction of the tray 21 and is used for pressing and fixing the modules on the tray 21 in the width direction; the trapezoidal screw mechanism is arranged in the length direction of the tray 21 and is used for fixing the modules on the tray 21 in the length direction; the tray unlocking mechanism 3 is connected with the spring pressing mechanism 24 and is used for driving the spring pressing mechanism 24 to release the modules before press shaping; the width direction press shaping mechanism 4 is arranged on both sides of the conveying system 2 and is used for applying pressure to the two sides of the width of the modules for shaping, which comprises a reference side 41 and a non-reference side 42, the extension position of the reference side 41 is fixed, and the extension position of the non-reference side 42 can be adaptively adjusted according to the width of the modules; the length direction press shaping mechanism 5 is located above the conveying system 2 and can move to the direction where the conveying system 2 is located, and is used for applying pressure to the end face of the modules for shaping and length fixing; the servo locking mechanism 6 is arranged above the conveying system 2 and is located on one side of the length direction press shaping mechanism 5, and is used for locking the length of the product modules after the length direction press shaping is completed; the automatic labeling system 7 is arranged on one side of the conveying system 2 and is used for automatically printing and pasting labels after the press shaping of the product modules is completed.

[0076] The conveying system 2 is the core transmission unit for the modules to enter and exit the processing station, and the conveying line 22 is a three-speed double-layer conveying line 22 to improve the conveying capacity; the tray 21 is the bearing carrier of the modules, and the spring pressing mechanism 24 in the width direction and the trapezoidal screw mechanism in the length direction are integrated thereon.

[0077] The conveying system 2 realizes the efficient entry and exit of the modules to the station through the three-speed double-layer conveying line 22, and the spring pressing mechanism 24 and the trapezoidal screw mechanism of the tray 21 respectively fix the modules from the width and length directions to avoid displacement of the modules during transmission; the blocking mechanism 23 stops the tray 21 to the preset station through the pneumatic blocking cylinder, and the mechanical non-return structure 232 prevents the tray 21 from rebounding, thereby jointly ensuring that the modules accurately and stably reach the processing position.

[0078] As shown in the drawings, Figure 2As shown, the spring pressing mechanism 24 is installed in the width direction of the tray 21, is a width direction assembly for fixing the mold group on the tray 21, and presses the mold group in the width direction by the elastic force of the spring, so as to press and fix the mold group in the width direction by the spring elastic force before and after the mold group is transported and pressure shaping, prevent the mold group from deviating due to vibration or external force during transportation, ensure the stability of the initial position of the mold group, and provide a reference for subsequent pressure shaping in the width direction.

[0079] Specifically, the spring pressing mechanism 24 includes a spring and a pressing block that presses the mold group under the elastic force of the spring, and the pressing block has a tendency to move towards the mold group under the elastic force of the spring to press the mold group when it is not unlocked.

[0080] The trapezoidal screw mechanism is installed at both ends of the tray 21 in the length direction, is a length direction assembly for fixing the mold group on the tray 21, adjusts the position of the pressing block through the screw transmission, is used for fixing the mold group in the length direction by adjusting the pressing block through the trapezoidal screw before and after the mold group is transported and pressure shaped, avoids displacement of the mold group in the length direction, at the same time provides a structural basis for subsequent docking of the length of the servo locking mechanism 6, ensures the initial fixing accuracy of the mold group in the length direction.

[0081] As shown, Figure 4 The blocking mechanism 23 is arranged along the conveying direction of the conveying line 22 and is composed of a pneumatic blocking structure 231 (including a blocking cylinder with a buffer function) and a mechanical non-return structure 232. The pneumatic blocking cylinder slows down the tray 21 to a preset station through the buffer function to avoid impact damage, and the mechanical non-return structure 232 prevents the tray 21 from rebounding to cause the pin of the pneumatic jacking positioning mechanism 8 to be misaligned, ensures the accurate and stable positioning of the tray 21, and guarantees the position accuracy of subsequent jacking positioning, pressure shaping and other processes.

[0082] Specifically, the pneumatic blocking structure 231 is arranged downstream of the preset station of the tray 21 and is used for stopping or releasing the tray 21; the mechanical non-return structure 232 is arranged upstream of the preset station and is used for avoiding the tray 21 from rebounding after being stopped.

[0083] More specifically, the pneumatic blocking structure 231 includes a blocking cylinder and a control valve for controlling the blocking cylinder. The mechanical non-return structure 232 includes a fixed seat 2321 and a blocking block 2322, the fixed seat 2321 is fixed upstream of the preset station, and the blocking block 2322 is arranged on the fixed seat 2321. The blocking block 2322 includes a first state and a second state; when the tray 21 passes through the blocking block 2322, the blocking block 2322 rotates / turns from the first state to the bottom end of the fixed seat 2321 to the second state to release the tray 21; after the tray 21 passes through the blocking block 2322, the blocking block 2322 rotates / turns from the second state to the first state to avoid the tray 21 from rebounding.

[0084] As shown, Figure 2As shown, the tray unlocking mechanism 3 is connected with the spring pressing mechanism 24, which is composed of an unlocking cylinder 31 and a pull block 32, and is used to drive the spring pressing mechanism 24 to release the module before pressure shaping, so that the module is completely released in the width direction, avoiding the interference of the friction force of the spring pressing mechanism 24 in the length direction of the module, ensuring the accuracy of the length direction pressure monitoring, and improving the length pressure shaping accuracy.

[0085] Specifically, the tray unlocking mechanism includes an unlocking cylinder 31 and a pull block 32; the output shaft of the unlocking cylinder 31 is connected with the pull block 32, and the pull block 32 is connected with the spring pressing mechanism 24; wherein the unlocking cylinder 31 can pull the pressing block of the spring pressing mechanism 24 away from the module through the pull block 32.

[0086] For example, the pull block 32 is connected with the pressing block of the spring pressing mechanism 24, and the pull block 32 drives the pressing block to move away from the module and compress the spring under the action of the unlocking cylinder 31.

[0087] As shown in Figure 5 The width direction pressure shaping mechanism 4 is arranged on both sides of the conveying system 2, the reference side 41 is fixed in the extended position by a hard limiting mechanism (such as a fixed limiting block), and the non-reference side 42 is limited by the module itself, and the extended position is self-adaptively adjusted according to the width of the module; both sides are driven by pneumatic actuators, and the gas inlet end is provided with a precision pressure reducing valve. Among them, the reference side 41 provides a fixed width reference, and the non-reference side 42 is self-adaptively adjusted according to the size of the module, and cooperates with the diameter difference of the cylinders on both sides and the precision pressure reducing valve, to ensure that the modules of different width sizes are uniformly pressed in the width direction, effectively eliminating the gap in the width direction of the module, correcting the size deviation, ensuring the consistency of the width size of the module, and adapting to the width shaping requirements of single, double and multiple modules.

[0088] Specifically, the reference side 41 and the non-reference side 42 are both driven by a pressurizing cylinder 43, and are guided by a sliding block and a corresponding sliding rail, and the gas inlet end of the pressurizing cylinder 43 is provided with a pressure reducing valve for controlling and monitoring the output force of the pressurizing cylinder 43; wherein the cylinder diameter ratio of the pressurizing cylinder 43 of the reference side 41 is greater than the cylinder diameter ratio of the pressurizing cylinder 43 of the non-reference side 42.

[0089] As shown in Figure 6 The length direction pressure shaping mechanism 5 is located above the conveying system 2 and can move along the Z axis (towards the conveying system 2), and after moving to the position by the Z axis, the floating tool 53 is driven by a servo cylinder to press the end face of the module, so as to realize shaping and length fixing.

[0090] Specifically, the length direction pressing and shaping mechanism 5 includes a Z-axis KP lock air cylinder 51, an end face servo cylinder pressing and fixed length structure 52, and a floating tool 53. The Z-axis KP lock air cylinder 51 is used to drive the length direction pressing and shaping mechanism 5 to move up and down along the Z-axis. The end face servo cylinder pressing and fixed length structure 52 is connected with the Z-axis KP lock air cylinder 51 and is powered by a servo motor and an electric cylinder, and is used to press and shape and fix the length of the module. The floating tool 53 is connected with the execution end of the end face servo cylinder pressing and fixed length structure 52, is used to contact the end face of the module, and is internally configured with a pressure sensor system. The floating tool 53 can press and shape the module under the driving of the end face servo cylinder pressing and fixed length structure 52.

[0091] Through the torque monitoring of the servo motor, the stroke monitoring of the electric cylinder, and the pressure monitoring of the pressure sensor system, the length direction of the module is accurately pressed and shaped and fixed.

[0092] The Z-axis KP lock air cylinder 51 can self-lock the air cylinder guide rod in the abnormal condition of power-off and air-off of the equipment, to ensure that the Z-axis movement stops. The end face servo cylinder provides stable pressing power. The floating tool 53 is attached to the end face of the module and monitors the pressure in real time through the pressure sensor. Combined with the torque of the servo motor and the stroke monitoring of the electric cylinder, the length direction of the module is accurately pressed and shaped and fixed, to ensure that the length of the module is consistent and meet the subsequent PACK package assembly precision requirements.

[0093] As shown in Figure 7 The servo locking mechanism 6 is located above the conveying system 2 and on one side of the length direction pressing and shaping mechanism 5. The servo locking mechanism 6 is driven by the X / Z-axis mechanism to connect with the trapezoidal screw of the tray 21 through the servo tightening structure 61, to rotate the screw to lock the length of the module. The laser ranging sensor 63 detects the length in real time.

[0094] After the length pressing and shaping is completed, the servo locking mechanism 6 locks the length of the module by connecting with the trapezoidal screw, to prevent the size deviation caused by the rebound of the module. The laser ranging sensor 63 feeds back the length data in real time, to ensure the fixed length accuracy and provide the final guarantee for the length stability of the module, to avoid the length change in the subsequent process.

[0095] Specifically, the servo locking mechanism 6 further includes the servo tightening structure 61, a multi-dimensional motion structure 62, and the laser ranging sensor 63. The multi-dimensional motion structure 62 is used to drive the servo tightening structure 61 to move in space. The multi-dimensional motion structure 62 at least includes an X-axis extension and retraction mechanism and a Z-axis lifting mechanism. The laser ranging sensor 63 is used to detect the length change of the module in real time during the locking process. The multi-dimensional motion structure 62 is configured to drive the servo tightening structure 61 to connect with the trapezoidal screw mechanism on the tray 21, and the trapezoidal screw mechanism is rotated by the servo tightening structure 61 to perform the fixed length locking action. The laser ranging sensor 63 provides length feedback for the fixed length locking action.

[0096] As shown in Figure 8 The automatic labeling system 7 is arranged on one side of the conveying system 2, and is used to print a module code according to line MES information, and the robot scans and checks, and then sucks and pastes the label. The automatic labeling system 7 can automatically complete the printing, checking and pasting of the module code, without manual intervention, thereby improving the production efficiency; the pneumatic sliding table avoids the interference between the robot and the printer, the code reader ensures that the label information is complete and readable and writable, the overpressure protection prevents the mechanism from being hard interfered when the label is pasted, thereby ensuring the accuracy and reliability of the labeling, and realizing the traceability of the module information and meeting the data management requirements of the production line.

[0097] Specifically, the automatic labeling system 7 comprises an automatic label printer 71, a labeling collaborative robot 72 and an end clamp 73. The automatic label printer 71 is provided with a pneumatic sliding table mechanism at the label outlet, which is used to receive the printed module code; the labeling collaborative robot 72 is arranged on one side of the automatic label printer 71; and the end clamp 73 is installed on the mechanical arm of the labeling collaborative robot 72; wherein the end clamp 73 is integrated with a code reader and a vacuum suction mechanism, and the vacuum suction mechanism is provided with an overpressure protection mechanism, which comprises a buffer spring and an overpressure sensor for detecting the compression amount of the spring.

[0098] Specifically, after the automatic product module press shaping is completed, the automatic module code printing module transmits the product information to the label printer device according to the line MES for printing the module code. After the printing of the module code is completed, the collaborative robot scans and reads the module code through the code reader carried by the end clamp 73. After the scanning and reading are correct, the vacuum suction mechanism of the end clamp 73 sucks and pastes the module code to the specified position above the product module.

[0099] The pneumatic sliding table mechanism arranged on the automatic label printer 71 is used to receive the module code printed by the label printer, thereby avoiding the interference between the end clamp 73 of the collaborative robot and the label printer. The end clamp 73 of the collaborative robot is provided with a code reader for verifying that the module code printed by the automatic label printer 71 is not damaged and is readable and writable.

[0100] The vacuum suction mechanism of the end clamp 73 of the collaborative robot is provided with an overpressure spring mechanism and an overpressure sensor for detecting, which is used to avoid the hard interference problem of the mechanism caused by the position and other reasons when the label module code is sucked and pasted. When the overpressure buffer spring is compressed to a specified maximum amount, the sensor detects and alarms and stops.

[0101] In some embodiments, the dual-module press shaping table further comprises a dual-cylinder pneumatic lifting positioning mechanism 8 arranged below the preset work station for lifting and positioning the tray 21; the dual-cylinder pneumatic lifting positioning mechanism 8 is provided with a set of positioning pins for cooperating with the corresponding pin holes on the bottom of the tray 21; the dual-cylinder pneumatic lifting positioning mechanism 8 is further provided with an RFID read-write head for reading and writing the module information in the chip on the tray 21.

[0102] The dual-cylinder pneumatic lifting positioning mechanism 8 is the core component for accurately positioning the tray 21; the core function is to complete the “lifting + positioning” action of the tray 21 by the power provided by the dual-cylinder after the tray 21 is stopped at the preset work station by the pneumatic blocking structure 231, so that the tray 21 is separated from the conveying line 22 and fixed at the accurate position required for processing.

[0103] The positioning pins include cylindrical pins and prismatic pins, which are arranged at the top of the dual-cylinder pneumatic lifting positioning mechanism 8 and accurately matched with the corresponding pin holes on the bottom of the tray 21, so as to realize the mechanical positioning of the tray 21 through “pin-hole cooperation”.

[0104] The RFID read-write head is installed on the dual-cylinder pneumatic lifting positioning mechanism 8 to read the chip on the tray 21 to obtain the information of the current module, and write the module process information into the chip after the processing is completed.

[0105] In some embodiments, the dual-module press shaping table further comprises a pneumatic three-in-one system for providing filtered, pressurized and lubricated compressed air to the cylinders in the tray unlocking mechanism 3 and the width direction press shaping mechanism 4.

[0106] The following is the processing process of the dual-module press shaping table:

[0107] The module is placed on the tray 21 and conveyed to the processing work station of the module press shaping table by the triple-speed double-layer conveying line 22 (speed chain) of the conveying system 2. At this time, the pneumatic blocking structure 231 (including blocking cylinder and mechanical non-return structure 232) in the conveying system 2 acts to accurately stop the tray 21; then the dual-cylinder pneumatic lifting positioning mechanism 8 is started to lift the tray 21 upward and complete the positioning (positioning method: the mechanism is provided with a set of cylindrical pins and prismatic pins which are accurately matched with the corresponding pin holes on the bottom of the tray 21 to realize the stable positioning of the tray 21).

[0108] The RFID read-write head installed on the dual-cylinder pneumatic lifting positioning mechanism 8 synchronously reads the current module information stored in the memory of the chip on the tray 21; at the same time, the tray unlocking mechanism 3 acts to drive the pull block 32 through the pneumatic actuator to pull open the spring compression mechanism 24 in the width direction of the tray 21, so that the module is in a completely open and unconstrained state in the width direction, avoiding the interference of friction force in the subsequent length press.

[0109] The width direction reference side 41 press shaping mechanism first extends and reaches a preset fixed position, then the width direction non-reference side 42 press shaping mechanism extends, and the extension distance is adaptively adjusted according to the actual width of the mold set, so that the other side of the mold set in the width direction is extruded, and the uniform press shaping in the width direction is completed.

[0110] The length direction press shaping mechanism 5 is lowered along the Z axis to the working position, then the end face servo cylinder at both ends is used to press the fixed length structure 52 and the floating tool 53, so that the pressure on both ends of the mold set in the length direction is applied, and the real-time monitoring of the pressure sensor is combined to complete the accurate press shaping and length fixing in the length direction.

[0111] After the above press shaping action is completed, the servo locking mechanism 6 is first lowered along the Z axis, and then is extended along the X axis to be accurately connected with the trapezoidal screw on the tray 21; then the servo motor is used to drive the trapezoidal screw to rotate, so that the screw nut and the pressing block are moved until the pressing block is tightly attached to the end face of the mold set in the length direction, and the length of the mold set is locked (the laser ranging sensor 63 detects the length change in real time to ensure the length fixing accuracy).

[0112] Then, the end face servo cylinder of the length direction press shaping mechanism 5 is retracted, and the whole is lifted along the Z axis to reset, and the reference side 41 and the non-reference side 42 press shaping mechanisms in the width direction are retracted to reset. The automatic label printer 71 prints the corresponding mold code according to the mold information read by the RFID read-write head and the task instruction issued by the production line MES system; the labeling collaborative robot 72 carries the code reader on the end gripper 73 to scan and verify the printed mold code, and after confirming that the mold code is intact and readable, the vacuum suction mechanism of the end gripper 73 is used to suck the mold code and paste it to the specified position above the mold set.

[0113] After the above procedures are all completed, the RFID read-write head writes the information that the mold set completes the process into the chip carried by the tray 21; then the double-cylinder pneumatic lifting positioning mechanism 8 is lowered to reset, the pneumatic blocking structure 231 is retracted to reset, the tray 21 is sent out by the conveying system 2 and leaves the station; finally, the pneumatic blocking structure 231 is extended to the position again, and the equipment enters the next processing cycle.

[0114] The present application not only has the functions of shaping, pressing and length fixing for single-row mold sets, double-row mold sets and multi-row mold sets, but also has the functions of automatically printing mold codes and automatically pasting mold codes. The whole device has the characteristics of high compatibility, full automation, man-machine cooperation, automatic data receiving and uploading, safety and reliability, stability and efficiency.

Especially, for the product embodiment described later, since it is corresponding to the method, the description is simple, and the relevant part is referred to the part of the system embodiment.

Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
