Description

Technical Field

[0001] The utility model relates to pressurizing equipment technology, in particular to a modular pressurizing equipment compatible with multiple models of products. Background Art

[0002] Currently, the production of new energy batteries requires adhesive bonding of battery cell modules. After the adhesive bonding process is complete, the module is pressurized to ensure that the adhesive is evenly applied to the battery cell. This pressure is maintained for a period of time to allow the adhesive to solidify, increasing the overall strength of the cured module, preventing loosening, and improving the battery's shock resistance and durability.

[0003] In existing processes, a vertical pressurizing mechanism is typically used to press the module downward and maintain pressure for a period of time to meet the process requirements for pressure application and holding. The modules within the PACK can be arranged in either a 2x2 or 2x3 configuration. These different layouts require different positioning of the pressure plate. When the module blueprint process changes, the pressure holding equipment needs to replace the pressure plate to accommodate the different battery modules. The replaced pressure plate requires re-processing, assembly, and commissioning, which increases time and costs, and reduces production line efficiency. Summary of the Invention

[0037] When pressurizing, the reaction force exerted on the pressurizing part of the adjustable-spacing pressurizing assembly 4 is fed back to the corresponding first pressure sensor assembly 3 and the second pressure sensor assembly respectively. The first pressure sensor assembly 3 and the second pressure sensor assembly respectively output the collected reaction force to the controller for adjusting the pressurizing pressure of the first pressing mechanism 2 and / or the pressing part of the second pressing mechanism.

[0038] The aforementioned pressure member is preferably a pressure plate with a compatible structure.

[0039] like Figure 2 As shown in FIG, in this embodiment, the first and second transverse support portions have the same structure, namely, a first support beam 10 and a second support beam 11, and the first and second movable portions have the same structure, namely, a first transverse slide 12 and a second transverse slide 13. Of course, other structures for achieving the transverse movement function may also be used, which will not be described in detail again.

[0040] like Figure 2 As shown in , this embodiment further includes a first fixed longitudinal beam 15 and a second fixed longitudinal beam 16, and the two ends of the first fixed longitudinal beam 15 and the second fixed longitudinal beam 16 are respectively connected to the corresponding ends of the first supporting beam 10 and the second supporting beam 11 to form a fixed support installation structure.

[0041] In this embodiment, a transverse driving structure 14 (preferably a driving motor) for driving the first transverse slide 12 and the second transverse slide 13 is provided on the first fixed longitudinal beam 15 or the second fixed longitudinal beam 16 .

[0042] Operation Description: The drive motor drives the sliding components on the first transverse slide 12 and second transverse slide 13 to move laterally via the drive shaft. The drive motor drives the front and rear drive shafts synchronously through the transfer case, synchronizing the speeds of the two drive shafts and ensuring synchronized movement of the moving components on the first transverse slide 12 and second transverse slide 13.

[0043] like Figure 5 As shown in , in this embodiment, the guide rail 40 is provided with an adjustment slot (not shown in the figure), and each of the pressure members 41 is fixed to the guide rail 40 by a fastener 42. Furthermore, the guide rail 40 is provided with a position sensor 43 for detecting the position of the pressure member 41.

[0044] Operation Description: Adjustable guide rail 40 is equipped with an adjustment slot. After loosening the clamping plate's fasteners 42, the clamping plate can slide on the guide rail 40 to adjust its position. After the position is adjusted, fasteners 42 are tightened to secure the clamping plate. Position sensor 43 detects the clamping plate's position to match the corresponding operating module.

[0045] like Figure 4 As shown in , in this embodiment, the first pressure sensor assembly 3 and the second pressure sensor assembly have the same structure, and both include an upper connecting plate 30 and a lower connecting plate 31 arranged relatively to each other, a pressure sensor 32 and a sensor controller 33, the pressure sensor 32 is arranged between the upper connecting plate 30 and the lower connecting plate 31, and the sensor controller 33 is arranged on the upper connecting plate 30 or the lower connecting plate 31.

[0046] like Figure 4 As shown in , further, in order to achieve uniformity and reliability in detecting the reaction force, the pressure sensors 32 are respectively provided on the four opposite corners of the upper connecting plate 30 and the lower connecting plate 31.

[0047] Operation Description: During the downward pressure of the first or second pressing mechanism, the guide rail and pressure plate contact the battery module, generating a downward pressure support reaction force. As the downward pressure distance increases, the downward pressure support reaction force gradually increases. The downward pressure support reaction force is transmitted to the four pressure sensors via the pressure plate and the lower connecting plate of the pressure sensor. The sensor controller 33 collects the signals from the four pressure sensors, integrates the pressure and value, and transmits them to the upper controller. If a pressure sensor fails, the sensor controller can monitor and detect the pressure sensor failure, display a fault alarm, and report it to the upper controller.

[0048] like Figure 3As shown in FIG, in this embodiment, the first pressing mechanism 2 and the second pressing mechanism have the same structure, and each includes a pressing bracket 20 and a pressing cylinder 21.

[0049] like Figure 3 As shown in , in this embodiment, an inspection pin shaft A is also included.

[0050] Instructions for use of the above inspection pin:

[0051] The first pressing mechanism and the second pressing mechanism are each provided with a set of maintenance pins.

[0052] During normal pressurization operation, the inspection pin is inserted into the sleeve on the pressurization bracket and the inspection pin does not work.

[0053] During maintenance, with the down-pressing mechanism retracted, remove the inspection pin from the sleeve on the pressure bracket and insert it into the inspection hole of the pressure bracket and the corresponding inspection hole of the down-pressing mechanism. This connects the pressure bracket and the down-pressing mechanism via the inspection pin, preventing the down-pressing mechanism from moving downward. The down-pressing mechanism and down-pressing cylinder (e.g., electric down-pressing cylinder) can then be disassembled for maintenance.

[0054] After the inspection is completed and the equipment is installed, the inspection pin is pulled out from the inspection port and inserted into the sleeve on the pressure bracket, and the pressing mechanism works normally.

[0055] A proximity sensor is installed at the manhole to detect the presence of a maintenance pin, providing safety protection. If a maintenance pin is detected, the system will shut down the cylinder. The cylinder will not resume its downward movement until the proximity sensor detects the absence of the maintenance pin.

[0056] The working principle of this utility model is briefly described as follows:

[0057] Action description: Take a 2x2 layout battery module as an example to explain, using a one-time pressing process.

[0058] Before operation, adjust the spacing between the pressure plates according to the size of the module poles and tighten the fasteners of the pressure plates to secure them.

[0059] After the battery module enters the workstation, the machine positions and fixes the battery module. The first transverse slide 12 and the second transverse slide 13 respectively drive the first pressing mechanism 2 and the second pressing mechanism to move above the battery module, and the two pressing mechanisms respectively drive the two sets of pressing plates to press down.

[0060] During the downward pressure process, the first pressure sensor assembly 3 and the second pressure sensor assembly respectively detect their respective downward pressures. After reaching the preset pressure, the downward pressure stops and the pressure maintenance begins. During the pressure maintenance period, the pressure sensor monitors the pressure value of the pressure plate in real time and adjusts the action of each downward pressure mechanism according to the monitored pressure value (when the pressure value is insufficient, the downward pressure mechanism moves downward to increase the downward pressure; when the pressure value is too large, the downward pressure mechanism moves upward to reduce the downward pressure) to ensure reasonable pressure. After the pressure is maintained for the set time, the downward pressure mechanisms are lifted up respectively, driving the pressure plate to separate from the battery module, completing the pressure-increasing and pressure-maintaining operation of the two groups of battery modules.

[0061] Taking the battery module with 2x3 layout as an example, the step-by-step pressing process is used.

[0062] Before operation, adjust the distance between the pressing plates according to the size of the module poles, and tighten the pressing plate fasteners 42 to fix the pressing plates.

[0063] After the battery module enters the workstation, the machine positions and fixes the battery module. The first transverse slide 12 and the second transverse slide 13 drive the first pressing mechanism 2 and the second pressing mechanism to move to the top of the two groups of battery modules on one side. The two pressing mechanisms respectively drive the two groups of pressure plates to press down for the first time. During the pressing process, the first pressure sensor assembly 3 and the second pressure sensor assembly respectively detect the pressing pressure. After reaching the preset pressure, the pressing is stopped and the two groups of modules begin to maintain pressure. During the pressure maintenance period, the pressure sensor 33 monitors the pressure value of the pressure plate in real time, and adjusts the action of the pressing mechanism according to the monitored pressure value to ensure reasonable pressure. After the pressure is maintained for the set time, the pressing mechanisms are lifted up respectively, driving the pressure plate to separate from the battery module.

[0064] The first transverse slide 12 moves again, causing the pressure plate of the first pressing mechanism 2 to move to above a group of battery modules that have not been pressed down, and the second pressing mechanism remains stationary. The pressure plate of the first pressing mechanism 2 is pressed down for the second time under the drive of the first pressing mechanism 2. During the pressing process, the pressure sensor 32 of the first pressure sensor assembly 3 detects the pressing pressure, stops pressing after reaching the preset pressure, and starts to maintain pressure. During the pressure maintenance period, the pressure sensor 32 monitors the pressure value of the pressure plate in real time, and adjusts the action of the pressing mechanism according to the monitored pressure value to ensure reasonable pressure. After maintaining pressure for the set time, the first pressing mechanism 2 is lifted up, driving the pressure plate of the first pressing mechanism 2 to separate from the battery module, completing the pressurization and pressure maintenance operation of the three groups of battery modules. The utility model realizes the pressing and pressurizing actions of modules with different layout forms, and realizes the rapid switching of the production of different modules without the need to replace new pressurizing parts, saving equipment costs, improving the adaptability of the equipment, solving compatibility problems, and improving the efficiency of production line operations.
