Description

Technical Field

[0001] This invention relates to the field of secondary battery manufacturing technology, specifically to a new energy power battery direct cooling plate base assembly machine. Background Technology

[0002] In the field of new energy vehicles, the main power source is the new energy power battery pack. To ensure the stable operation of the battery pack, a direct cooling plate is required during battery assembly to achieve temperature control and heat dissipation of the battery cells. The battery direct cooling plate needs to be pre-fixed on the base to form a cooling integrated assembly. In the existing assembly process, multiple positioning lugs are integrally formed on both sides of the direct cooling plate, and the base has corresponding slots. The conventional assembly method relies on manual placement of the direct cooling plate into the corresponding fixture, and then controlling the drive pressure component to bend the lugs. Each bend can only be operated on one end. When completed, the operator needs to switch the battery to the other end, then reposition the base, and control the drive pressure component to bend the lugs again. Multiple operations affect the assembly efficiency of the direct cooling plate.

[0003] Meanwhile, the pressure-driven components are usually set as fixed-shape push block structures. They use pushing pressure to drive the ear plate to bend. After the ear plate is bent, the push block and the ear plate tend to be parallel, resulting in poor subsequent plastic shaping effect of the push block on the ear plate. This can easily cause the ear plate to warp due to metal springback, thereby reducing the ear plate's fit with the groove and causing the base to have a risk of loosening. Summary of the Invention

[0016] 2. This new energy power battery direct cooling plate base assembly machine, through the cooperation of the end pressure plate and the end bending mechanism, allows the movable pressure plate to not only directly bend the ear plate used to fix the base block, but also, when the stop protrusion of the movable pressure plate contacts the ear plate, the bending pressure block can directly form a pressing force that tends to be perpendicular to the ear plate at the movable head of the ear plate. At this time, the stop protrusion directly acts on the bending point of the ear plate, forming a multi-point continuous pressing state, ensuring the shaping effect of the ear plate, thereby effectively improving the bending effect of the ear plate, avoiding the possibility of the ear plate lifting due to direct pushing of the ear plate, and enabling the bent ear plate to fit closely to the slot of the base block, thereby effectively ensuring the assembly quality of the battery direct cooling plate and the base block.

[0017] 3.

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example Please see Figures 1-13 A new energy power battery direct cooling plate base assembly machine includes an installation base plate 1, a workpiece bearing mechanism 2, a lateral positioning mechanism 3, a lateral pushing and bending mechanism 5, and an end multi-station bending mechanism 6. The mounting base plate 1 is the equipment bearing base, and the workpiece bearing mechanism 2, the lateral positioning mechanism 3, the lateral pushing and bending mechanism 5 and the end multi-station bending mechanism 6 are modularly fixedly installed on the top of the mounting base plate 1. The workpiece carrying mechanism 2 includes a mounting bracket and a top carrying plate. The top carrying plate is installed in the middle of the mounting base plate 1, and a battery direct cooling plate 7 is placed on the top of the workpiece carrying mechanism 2. The lateral positioning mechanism 3 is disposed on both sides of the workpiece bearing mechanism 2. The lateral positioning mechanism 3 is used to press down and fix both sides of the battery direct cooling plate 7 to achieve the fixation of the battery direct cooling plate 7. The multi-station bending mechanism 6 is installed on both sides of the battery direct cooling plate 7. The multi-station bending mechanism 6 includes a sliding support 61 and a bottom slide rail 62. The bottom slide rail 62 is fixedly installed on the top of the mounting base plate 1. The sliding support 61 is slidably connected to the top of the bottom slide rail 62. A clamping block 69 is fixedly connected inside the sliding support 61. The clamping block 69 clamps the base block 8. The sliding support 61 controls the base block 8 at both ends of the battery direct cooling plate 7 through the clamping block 69. The ear plates of the battery direct cooling plate 7 and the slots of the base block 8 are matched one-to-one. The sliding support 61 is also provided with several sets of end bending mechanisms 68. The end bending mechanism 68 is adapted to the number of ear plates and is used to synchronously press and clamp the ear plates into the slots. The lateral pushing and bending mechanism 5 is arranged at the four corners of the battery direct cooling plate 7, and the lateral pushing and bending mechanism 5 is used to push and bend the lateral ear plates of the battery direct cooling plate 7.

[0023] It should be noted that the mounting base plate 1 has several slots and mounting holes. The workpiece bearing mechanism 2, the lateral positioning mechanism 3, the lateral pushing and bending mechanism 5, and the end multi-station bending mechanism 6 are all installed through the slots or mounting holes, and the lateral positioning mechanism 3, the lateral pushing and bending mechanism 5, and the end multi-station bending mechanism 6 are arranged symmetrically.

[0024] In an optional embodiment, a correction push block 4 is installed on the top of the mounting base plate 1, and a correction motor is provided on the outside of the correction push block 4. The correction motor is fixedly connected to the top of the mounting base plate 1 through a motor bracket. The lateral positioning mechanism 3 includes a support frame 31, and a guide push block 32 and a side pressure plate 33 are provided on the top of the support frame 31. A side pressure connecting rod 34 for deflection transmission is provided between the guide push block 32 and the side pressure plate 33. A pneumatic motor 35 is fixedly installed on the top of the support frame 31, and the output end of the pneumatic motor 35 is used to push the guide push block 32.

[0025] It should be noted that the battery direct cooling plate 7 is placed on top of the workpiece bearing mechanism 2 by a robotic arm, and then the lateral position of the battery direct cooling plate 7 is adjusted by the correction push block 4 so that the end of the battery direct cooling plate 7 is matched with the position of the base block 8. Start the pneumatic motor 35, which drives the guide block 32 to move upward. The guide block 32 drives the side pressure plate 33 to deflect to the side and downward through the side pressure connecting rod 34 until the side pressure plate 33 presses against the top of the battery direct cooling plate 7, thus fixing the battery direct cooling plate 7 and ensuring the stability of the battery direct cooling plate 7 when assembling the base block 8.

[0026] refer to Figures 1-4In an optional embodiment, the sliding support 61 is rotatably connected to a control lever 63, the control lever 63 is movably connected to a transmission link 64, and the end of the transmission link 64 away from the control lever 63 is rotatably connected to an adjustment lever 65, which is rotatably mounted on the top of the mounting base 1.

[0027] It should be noted that the control lever 63, the transmission link 64, and the adjustment lever 65 constitute a crank-rocker mechanism. The adjustment lever 65 is equipped with an operating handle, which is used to drive the adjustment lever 65 to rotate. During the rotation of the adjustment lever 65, the transmission link 64 is driven to rotate. The transmission link 64 drives the sliding support seat 61 to slide on the top of the bottom slide rail 62 through the control lever 63.

[0028] Specifically, the base block 8 is snapped into the clamping block 69 to fix the base block 8. At the same time, after the battery direct cooling plate 7 is placed and fixed, the control rod 65 is used to drive the sliding support 61 to move towards the battery direct cooling plate 7, so that the base block 8 and the end of the battery direct cooling plate 7 are in contact, and at this time the ear plate of the battery direct cooling plate 7 is adapted to the slot of the base block 8.

[0029] refer to Figure 4 In an optional embodiment, the sliding support 61 is internally connected to an end pressure plate 66, which is provided in two sets, upper and lower. The two sets of end pressure plates 66 are respectively provided on the upper and lower sides of the clamping block 69. An end pressing motor 67 is provided on the outside of each set of end pressure plates 66. Several end bending mechanisms 68 are installed on the outside of the end pressure plates 66. Side positioning pressure rods 610 are provided on both sides of the sliding support 61, and the side positioning pressure rods 610 are clamped on both sides of the base block 8.

[0030] It should be noted that the end pressing motor 67 is used to drive the two sets of end pressing plates 66 to move in the same direction or in opposite directions respectively. When the two sets of end pressing plates 66 move in the same direction, the end pressing plates 66 bend the ear plates of the battery direct cooling plate 7 through the end bending mechanism 68, and drive the ear plates to bend into the slot of the base block 8, thereby completing the assembly operation of the battery direct cooling plate 7 and the base block 8.

[0031] Furthermore, sliding support seats 61 with synchronous drive are set on both sides, and both are driven by control rods 65. At the same time, the sliding support seats 61 are provided with end pressure plates 66 and end bending mechanisms 68 distributed vertically. The end bending mechanisms 68 on both sides simultaneously bend the upper and lower ear plates of the battery direct cooling plate 7, and complete the bending and snap-fit ​​assembly of all ear plates in one go, which effectively improves the assembly efficiency. Moreover, the end bending mechanisms 68 on both sides simultaneously apply pressure to the battery direct cooling plate 7, which effectively ensures the force balance on both sides of the battery direct cooling plate 7 and reduces the damage to the battery direct cooling plate 7 during the assembly process.

[0032] By using sliding support seats 61 at both ends and end bending mechanisms 68 distributed vertically on the sliding support seats 61, the ear plates at both ends of the battery direct cooling plate 7 are simultaneously bent and controlled, allowing the base block 8 to be assembled simultaneously at both ends of the battery direct cooling plate 7. At the same time, the ear plate at one end of the battery direct cooling plate 7 is bent and controlled to be in the slot of the base block 8 in one go. Several ear plates are bent and engaged in the slot simultaneously, thereby effectively improving the ear plate pressing efficiency of the battery direct cooling plate 7. Furthermore, the simultaneous assembly of the battery direct cooling plate 7 at both ends reduces the end positioning of the battery direct cooling plate 7. It is only necessary to control the battery direct cooling plate 7 to be placed on top of the workpiece bearing mechanism 2, and then the positioning operation can be completed by the lateral positioning mechanism 3, reducing the overall positioning and clamping requirements.

[0033] It should be noted that the side positioning pressure rod 610 is used to laterally position the base block 8. The side positioning pressure rod 610 and the sliding support seat 61 are slidably inserted. A side positioning spring is provided between the side positioning pressure rod 610 and the sliding support seat 61. The side positioning pressure rod 610 presses against both sides of the movable base block 8. When the pressure of the side positioning springs on both sides is balanced, the side positioning pressure rod 610 clamps the base block 8 at the center position of the sliding support seat 61, thereby ensuring the accuracy of the clamping block 69 clamping the base block 8 and facilitating the docking of the base block 8 and the battery direct cooling plate 7.

[0034] refer to Figure 8 and Figure 10 In an optional embodiment, the end bending mechanism 68 includes a movable pressure plate 681 and a drive plate 682, which are slidably connected to each other. The drive plate 682 is fixedly installed outside the end pressure plate 66. A top pressure spring 683 is provided between the movable pressure plate 681 and the drive plate 682. A guide groove 684 is fixedly connected to the side of the movable pressure plate 681. A bending block 685 is slidably connected to the outside of the guide groove 684. A pushing rod 686 is rotatably connected to the top of the bending block 685. The end of the pushing rod 686 away from the bending block 685 is rotatably connected to the drive plate 682. A stop protrusion is provided on the outside of the movable pressure plate 681.

[0035] It should be noted that when the end bending mechanism 68 bends the ear plate, the end pressure plate 66 drives the drive plate 682 to move towards the ear plate. The drive plate 682 drives the movable pressure plate 681 to move downward through the top pressure spring 683. Then the movable pressure plate 681 contacts the ear plate of the battery direct cooling plate 7, driving the ear plate to bend into the slot of the base block 8.

[0036] Furthermore, when the stop protrusion of the movable pressure plate 681 contacts the ear plate, the movement of the movable pressure plate 681 is restricted by the stop protrusion. At this time, when the end pressure plate 66 continues to move downward, the end pressure plate 66 drives the drive plate 682 to move closer to the ear plate relative to the movable pressure plate 681. Then the drive plate 682 compresses the top pressure spring 683. At the same time, the drive plate 682 drives the bending pressure block 685 to slide along the guide groove 684 closer to the ear plate through the push rod 686. At the same time, the bending pressure block 685 acts as a lever under the action of the push rod 686, so that the movable end of the bending pressure block 685 has a synchronous pushing force towards the movable pressure plate 681, so that the bending pressure block 685 acts perpendicularly to the bent ear plate. During bending, the pressure is maintained for 2-5 seconds to complete the plastic shaping of the ear plate and suppress the amount of metal springback.

[0037] Furthermore, through the cooperation of the end pressure plate 66 and the end bending mechanism 68, the movable pressure plate 681 can not only directly bend the ear plate used to fix the base block 8, but also, when the stop protrusion of the movable pressure plate 681 contacts the ear plate, the bending pressure block 685 can directly form a pressing force that tends to be perpendicular to the ear plate at the movable head of the ear plate. At this time, the stop protrusion directly acts on the bending point of the ear plate, forming a multi-point continuous pressing state, ensuring the shaping effect of the ear plate, thereby effectively improving the bending effect of the ear plate, avoiding the possibility of the ear plate lifting due to direct pushing of the ear plate, and enabling the bent ear plate to fit more closely in the slot of the base block 8, thereby effectively ensuring the assembly quality of the battery direct cooling plate 7 and the base block 8.

[0038] In an optional embodiment, the width of the movable pressure plate 681 and the bending pressure block 685 is adapted to up to two sets of ear plates, the number of movable pressure plates 681 and the bending pressure block 685 is adapted to the number of ear plates, and several movable pressure plates 681 slide independently outside the end pressure plate 66.

[0039] refer to Figure 4 , Figure 6 , Figure 7 and Figure 9In an optional embodiment, the lateral pushing and bending mechanism 5 includes a lateral pushing motor 51, which is fixedly mounted on the top of the mounting base plate 1 via a mounting plate and a bracket. A drive slider 52 is fixedly connected to the output end of the lateral pushing motor 51. A lateral bending mechanism 53 is mounted outside the drive slider 52. The lateral bending mechanism 53 includes a lateral pushing and bending plate 531, with a bending jaw 532 at its end and a lateral pressing guide groove 533 on its outer surface. A movable slide plate 534 is slidably connected to the outside of the side pressure guide groove 533. A side pressure block 538 is fixedly connected to one end of the movable slide plate 534. A hinge plate 536 is rotatably connected to the other end of the movable slide plate 534. A tail push plate 535 is rotatably connected to the end of the hinge plate 536 away from the movable slide plate 534. The tail push plate 535 and the side push folding plate 531 are slidably connected. The tail push plate 535 is fixedly installed on the outside of the drive slider 52. A push plate spring 537 is provided between the tail push plate 535 and the side push folding plate 531.

[0040] refer to Figure 9 It should be noted that when the end ear plates of the battery direct cooling plate 7 and the base block 8 are pressed together, the side ear plates of the battery direct cooling plate 7 and the base block 8 are bent and pressed together.

[0041] Specifically, the side push motor 51 starts, and the side push motor 51 drives the tail push plate 535 to move towards the side ear plate of the battery direct cooling plate 7 via the drive slider 52. The tail push plate 535 pushes the side push folding plate 531 via the push plate spring 537. The side push folding plate 531 bends the ear plate via the bending jaw 532. When the bottom groove of the bending jaw 532 contacts the ear plate, the drive slider 52 continues to slide closer to the ear plate. The drive slider 52 drives the tail push plate 535 to move closer to the side push folding plate 531. The tail push plate 535 compresses the push plate spring 537. The tail push plate 535 pushes the movable slide plate 534 to move closer to the ear plate via the hinge plate 536. At the same time, the movable slide plate 534 slides along the side pressure guide groove 533, and the hinge plate 536 forms a lever effect on the movable slide plate 534, so that the movable slide plate 534 drives the side pressure block 538 to form pressure in the direction perpendicular to the plane of the bent ear plate.

[0042] With the combined use of the side-pushing folding plate 531 and the side-pressing block 538, the side-pushing folding plate 531 initially pushes and folds the ear plate, pressing the ear plate into the slot of the base block 8. When the ear plate is pressed into the slot, the side-pressing block 538 further applies pressure in the direction perpendicular to the ear plate, effectively improving the pushing and pressing effect on the side ear plate, preventing the side ear plate of the battery direct cooling plate 7 from warping, and ensuring that after the ear plate is bent, the side ear plate of the battery direct cooling plate 7 can completely fit the base block 8, thereby further improving the assembly effect of the battery direct cooling plate 7 and the base block 8.

[0043] refer to Figure 13In an optional embodiment, both the end multi-station bending mechanism 6 and the lateral pushing bending mechanism 5 are provided with a bending execution display mechanism 11. The bending execution display mechanism 11 includes an oil injection plunger rod 111. An oil inlet 112 is provided at the end of the oil injection plunger rod 111. A driven piston block 113 is movably connected inside the oil injection plunger rod 111. A pressure gauge rod 114 is fixedly connected to the outside of the driven piston block 113. A gauge sleeve 115 is threadedly connected to the other end of the oil injection plunger rod 111. The gauge sleeve 115 is fitted onto the outside of the pressure gauge rod 114. A color bar is provided on the outside of the pressure gauge rod 114, and the color bar is marked with different colors.

[0044] In an optional embodiment, the oil injection plunger rod 111 is provided with several sets, which are respectively adapted to the end multi-station bending mechanism 6 and the lateral push bending mechanism 5. The bending execution shaping mechanism 11 also includes a pressure measuring rod 116 fixedly connected to the outside of the tail push plate 535. The pressure measuring rod 116 has an internal movable oil pressure piston block 117. An oil pressure push rod 118 is fixedly connected to the outside of the oil pressure piston block 117. The oil outlet end of the pressure measuring rod 116 is provided with an oil outlet 119. A connecting oil pipe is connected between the oil outlet 119 and the oil inlet 112.

[0045] In an optional embodiment, the pressure measuring rod 116 is fixedly connected to the tail push plate 535, the oil pressure push rod 118 is fixedly connected to the side push baffle 531, and the pressure measuring rod 116 is fixedly connected to the drive plate 682, and the oil pressure push rod 118 is fixedly connected to the movable pressure plate 681.

[0046] It should be noted that the bending execution display mechanism 11 is used to visually display the bending test status of the bending mechanism 68 and the side bending mechanism 53 at different ends. It judges the matching status of the ear plate and the slot by detecting the pressure data. When the detected pressure exceeds the preset safety setting value or is lower than the setting value, the assembly is abnormal and manual observation or adjustment is required to further ensure the matching status of the ear plate and the slot.

[0047] The preset safety setting value is the ear plate bending pressure required by the workers, which is within the safe bending error range of the ear plate during the ear plate bending process.

[0048] Specifically, the movable pressure plate 681 and the end bending pressure block 685 are matched with the number of ear plates. When the movable pressure plate 681 and the end bending pressure block 685 work together to press the ear plate, the distance between the drive plate 682 and the movable pressure plate 681 is reduced. Then the oil pressure push rod 118 pushes the oil pressure piston block 117. The hydraulic oil inside the pressure measuring rod 116 is pushed into the oil injection plunger rod 111 through the connecting oil pipe. Its hydraulic oil pushes the driven piston block 113 to slide upward. The driven piston block 113 drives the pressure measuring rod 114 to move upward, so that the end of the measuring rod sleeve 115 points to different color block areas of the pressure measuring rod 114. The working state of the entire set of end bending mechanisms 68 is determined by judging the color block area pointed to by the pressure measuring rod 114.

[0049] Similarly, when the side bending mechanism 53 is working, the hydraulic oil inside the oil injection plunger rod 111, which is adapted to the side bending mechanism 53, synchronously pushes the pressure gauge rod 114 to realize the pressure detection of the side bending mechanism 53.

[0050] When the ear plate is missing or the ear plate is not pressed, when the normal end bending pressure block 685 is pressed, the end bending pressure block 685 of the missing part is relatively less compressed. The distance between its movable pressure plate 681 and drive plate 682 is greater than the distance during normal pressing. As a result, the pressure gauge rod 114 of the bending execution display mechanism 11 points to different color block areas, making it easy to see the assembly effect of the battery direct cooling plate 7 and the base block 8 with the naked eye.

[0051] When the ear plate is subjected to torque or folding, the thickness of the ear plate increases. Due to the increased pressure, the indicator color block area of ​​the bending execution display mechanism 11 changes synchronously. By using the change in the directional color gamut, the bending state can be quickly determined.

[0052] By setting up the bending execution display mechanism 11, the assembly status of the battery direct cooling plate 7 and the base block 8 can be effectively and quickly reflected intuitively, which facilitates quick judgment of assembly quality, reduces the trouble of subsequent secondary inspection, and improves the overall assembly quality and device efficiency of the battery direct cooling plate 7 and the base block 8.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
