DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0040] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0042] The following describes the energy storage battery box pressure test tool according to the embodiment of the present application with reference to the accompanying drawings.

[0043] See also Figure 1-Figure 14 According to the embodiment of the present application, the energy storage battery box pressure test tooling includes: an equipment frame mechanism 1, a pressure-resistant equipment host 2, a battery box clamping and conveying mechanism 3, a test pressing mechanism 4 and a pressing and positioning mechanism 5.

[0044] The equipment frame mechanism 1 is used to support and install the battery box clamping and conveying mechanism 3, the test pressing mechanism 4 and the holding and positioning mechanism 5, and the battery box is subjected to a pressure test through the cooperation of the pressure-resistant equipment host 2 and the test pressing mechanism 4. The holding and positioning mechanism 5 replaces the original cylinder setting, which can realize a more convenient battery box clamping operation.

[0045] See also Figure 1-Figure 5 and Figure 8 The equipment frame mechanism 1 includes a base frame 11 and a chassis 12. The chassis 12 is arranged in the middle above the base frame 11, and the battery box loading station and unloading station are respectively arranged above the base frame 11 on both sides of the chassis 12. A guide rail 13 and a beam plate 14 are installed above the base frame 11. The pressure-resistant equipment host 2 is located on one side of the equipment frame mechanism 1. The battery box clamping and conveying mechanism 3 includes a base plate 31 and a motor 32. A guide seat 34 matching the guide rail 13 is arranged at the bottom of the base plate 31, and the motor 32 is installed at the bottom of the base plate 31, and a pressure wheel 33 in contact with the beam plate 14 is fixedly provided at the output shaft end of the motor 32. A first limit assembly 35 and two sets of second limit assemblies 36 arranged oppositely are respectively arranged at three positions above the base plate 31. The test pressing mechanism 4 is installed inside the chassis 12 to press down and detect the battery box. The holding and positioning mechanism 5 includes a support 51, a fixed seat 53, an elastic support portion 54 and a support arm 55. The support arm 55 is fixed on the upper side of the bottom plate 31 away from the first limit assembly 35. The elastic support portion 54 penetrates the fixed seat 53 to connect the support 51 and the support arm 55. A guide clamping plate 52 is provided on the side of the support 51 away from the elastic support portion 54. A damping seat 6 is installed on the guide rail 13. The end of the support arm 55 away from the elastic support portion 54 is connected to the damping seat 6.

[0046] When preparing to load the battery box, the battery box clamping and conveying mechanism 3 is located at the loading station above the bottom frame 11 on one side of the chassis 12. The battery box is placed between the first limit assembly 35, the second limit assembly 36 and the guide clamp 52 above the bottom plate 31. At this time, the guide clamp 52 is pulled away from the side wall of the battery box by the elastic support part 54, that is, there is a certain gap between the guide clamp 52 and the outer wall of the placed battery box. After the loading of the battery box in the loading section is completed, the motor 32 drives the pressure wheel 33 at the end of the output rod to rotate. Since the rotating pressure wheel 33 is in contact with the beam plate 14, the rotating pressure wheel 33 also drives the motor 32 and the bottom plate 31 to move along the guide rail 13 at the same time. In the path where the bottom plate 31 drives the upper battery box to move to the bottom of the test pressing mechanism 4, the moving bottom plate 31 drives the fixed seat 53 to move synchronously. Due to the resistance of the damping seat 6, when the guide clamp 52 does not contact the side wall of the battery box, the damping seat 6 sliding on the guide rail 13 is slower than the bottom plate 31 moving on the guide seat 34, that is, a speed difference is generated during movement. The speed difference during movement eventually becomes a displacement difference. After the guide clamp 52 gradually approaches until it is finally clamped on the side wall of the battery box, the damping seat 6 and the bottom plate 31 will move forward synchronously. The specific direction of movement of the damping seat 6 and the bottom plate 31 at this time is from the loading station to the testing station (refer to the attached Figure 2 , the left side above the chassis 11 is the loading station, the middle part above the chassis 11 is the testing station, and the right side above the chassis 11 is the unloading station), and finally the battery box is fed to the bottom of the test pressing mechanism 4 in a clamped and fixed manner. The test pressing mechanism 4 cooperates with the pressure-resistant equipment host 2 to test the battery box, and after the test is completed. The motor 32 continues to drive the clamped battery box above the bottom plate 31 to move to the unloading station above the chassis 11. After the tested battery box moves to the unloading station, the motor 32 drives the pressure wheel 33 to rotate in the opposite direction for a small distance, and the bottom plate 31 and the battery box both move backward a short distance. Due to the resistance of the damping seat 6, the damping seat 6 will not move backward synchronously with the bottom plate 31. Due to the lag in the movement of the damping seat 6, a gap is generated between the guide clamp 52 and the battery box again, and the battery box above the bottom plate 31 can be taken out at this time. After the battery box is taken out, the motor 32 drives the battery box clamping and conveying mechanism 3 to move as a whole and reset to the loading station. When the battery is reset and moved to the loading station, under the resistance of the damping seat 6, the battery box can be loaded again between the guide clamping plate 52 and the first limiting assembly 35 to complete the above-mentioned cycle operation.

[0047] The energy storage battery box pressure test fixture adopts the combination of the pressure holding positioning mechanism 5 and the damping seat 6 to replace the traditional cylinder clamping method, and the clamping and control are carried out while the battery box clamping and conveying mechanism 3 moves, which is more convenient to control. Compared with the method of installing multiple sensors and coordinating control systems, it can effectively save the cost of equipment clamping operation.

[0048] In the above specific implementation, please refer to Fig.10 The damping seat 6 includes a seat shell 61, a first piston plate 63, a second piston plate 64, a first roller 65 and a cover plate 66. An upper oil storage chamber 621 is provided on the top of the seat shell 61, and a lower oil storage chamber 622 is provided inside the seat shell 61 near the slot opening. The upper oil storage chamber 621 and the lower oil storage chamber 622 are connected through a guide hole 623. The first piston plate 63 is located inside the upper oil storage chamber 621. A cover plate 66 is fixed on the top of the upper oil storage chamber 621. The cover plate 66 and the seat shell 61 are detachably fixed by bolts. An adjusting bolt 67 is threadedly provided on the cover plate 66, that is, a threaded hole that is threadedly matched with the adjusting bolt 67 is provided on the cover plate 66, and the bottom end of the adjusting bolt 67 is rotatably arranged with the first piston plate 63, the second piston plate 64 is located inside the lower oil storage chamber 622, and multiple groups of first rollers 65 are installed on the side of the second piston plate 64 close to the slide groove mouth, and the bottom end of the support arm 55 is fixed to the seat shell 61 by welding.

[0049] The seat shell 61 can slide with the guide rail 13 through the slot opening at the lower middle part, and the first roller 65 at the side of the slot opening contacts the side of the guide rail 13. The upper oil storage chamber 621 on the seat shell 61 is pre-filled with oil, and the adjusting bolt 67 is turned to drive the first piston plate 63 to gradually move downward inside the upper oil storage chamber 621 to compress the oil inside the upper oil storage chamber 621. The oil inside the upper oil storage chamber 621 is consistent with the pressure of the oil in the lower oil storage chamber 622 through the guide hole 623. When the oil inside the upper oil storage chamber 621 is pressurized, the oil inside the lower oil storage chamber 622 is also pressurized to squeeze the second piston plate 64 and the first roller 65 on one side, so that the first roller 65 can be more firmly attached to the side of the guide rail 13, and the seat shell 61 has greater friction when moving on the guide rail 13. The displacement difference between the bottom plate 31 and the seat shell 61 is achieved when the bottom plate 31 moves from the loading station to the detection station. Similarly, when the bottom plate 31 and the seat shell 61 move synchronously to the unloading station and then move in the opposite direction for a short distance, a certain displacement difference will be generated between the bottom plate 31 and the seat shell 61. The displacement difference generated adjusts the distance between the guide clamp 52 and the side wall of the battery box.

[0050] Furthermore, the side of the seat shell 61 is provided with an oil filling end pipe 68 connected to the upper oil storage chamber 621, and a one-way valve 69 is provided outside the oil filling end pipe 68. Additional oil can be injected into the upper oil storage chamber 621 through the oil filling end pipe 68.

[0051] For details, please refer to Figure 5 and Figure 6The first limiting assembly 35 and the second limiting assembly 36 have the same structural specifications. The first limiting assembly 35 includes a frame 351 and a limiting block 352. The frame 351 is fixed to the top of the bottom plate 31. The limiting block 352 is arranged on the side of the frame 351 close to the battery box. The back of the frame 351 is provided with a belly plate 353. The limiting block 352 in the first limiting assembly 35 is used to limit the battery box.

[0052] For specific settings, see Figure 7 The test pressing mechanism 4 includes a pressure test plate 41, a hydraulic cylinder 42 and a fixing frame 44. The hydraulic cylinder 42 is installed on the top of the chassis 12, and the fixing frame 44 connects the output rod end of the hydraulic cylinder 42 and the pressure test plate 41. The output rod end of the hydraulic cylinder 42 drives the pressure test plate 41 to move in the vertical direction, and can press down to test the battery box below. The test pressing mechanism 4 also includes a guide column 43, the bottom end of the guide column 43 is fixedly connected to the fixing frame 44, and the guide column 43 moves through the top wall of the chassis 12. The setting of the guide column 43 is to improve the stability of the pressure test plate 41 when it moves in the vertical direction.

[0053] In the above specific implementation, please refer to Fig. 9 The elastic support part 54 includes a seat block 541, a push rod 542 and a first spring 543. The two ends of the push rod 542 are respectively connected to the support 51 and the seat block 541, the seat block 541 is fixedly connected to the top of the support arm 55, and the first spring 543 is sleeved on the outside of the push rod 542. The side of the fixed seat 53 is provided with a through hole matched with the push rod 542, and the first spring 543 is sleeved on the outside of the push rod 542 located between the fixed seat 53 and the seat block 541. The push rod 542, the seat block 541 and the support arm 55 form a connecting rod for connecting the support 51 and the damping seat 6. Since the elastic support part 54 between the fixed seat 53 and the seat block 541 plays a certain buffering role, it prevents the guide splint 52 from being too rigid to squeeze the battery box above the bottom plate 31, and has a good protective effect on the tested battery box.

[0054] For details, please refer to Figure 8 The upper section of the guide clamp plate 52 is tilted outwards, and the overall structure is an obtuse V-shaped structure. The upper section of the guide clamp plate 52 is an outward tilted section, which has a certain guiding effect on the loading battery box, that is, it makes it easier to place the loading battery box on the bottom plate 31 between the first limit assembly 35, the second limit assembly 36 and the guide clamp plate 52. The lower section of the guide clamp plate 52 is a vertical section, which is used to cooperate with the first limit assembly 35 to clamp the battery box.

[0055] The first roller 65 in the damping seat 6 of the energy storage battery box pressure test fixture is in long-term rolling contact with the side wall of the guide rail 13. In order to reduce the wear between the first roller 65 and the guide rail 13, it is necessary to manually apply lubricating oil to the first roller 65 after a period of time. Manual operation to apply lubricating oil is not only inconvenient, but also there are multiple groups of first rollers 65, and it is difficult to quickly and evenly apply lubricating oil to the roller surfaces of multiple groups of first rollers 65.

[0056] See also Figure 10-Figure 14 The energy storage battery box pressure test fixture also includes a pressure relief lubrication assembly 7, which includes a second roller 71, a pin 72, and a second spring 73. The first roller 65 includes a wheel seat 651 and a wheel 652, and the wheel 652 is rotatably mounted on the wheel seat 651. The wheel seat 651 is fixed to the side of the second piston plate 64, and the wheel seat 651 and the second piston plate 64 can be connected by welding. The side of the wheel seat 651 is provided with an end side through hole 654, and the side of the wheel seat 651 is provided with a connecting pipe that penetrates the second piston plate 64. The wheel seat 651 is vertically provided with a guide groove 653 connected with the guide groove 653, the top wall of the lower oil storage chamber 622 is provided with a mounting groove 611, the mounting groove 611 is directly above the guide groove 653, the second spring 73 is provided inside the mounting groove 611, the pin 72 is slidably provided inside the guide groove 653, and the side of the pin 72 is provided with a connecting hole 74 connected with the end side through hole 654. The second roller 71 is installed at the bottom of the pin 72, the bottom frame 11 is provided with a supporting horizontal plate 16, and the supporting horizontal plate 16 is provided with a pad plate 15, and the two ends of the pad plate 15 are designed with a slope surface 151 structure.

[0057] The present application also provides an embodiment in which lubricating oil is added to the upper oil storage chamber 621 and the lower oil storage chamber 622. The adjusting bolt 67 is rotated to drive the first piston plate 63 to move downward inside the upper oil storage chamber 621 to pressurize the lubricating oil inside the upper oil storage chamber 621, so that the lubricating oil inside the lower oil storage chamber 622 is pressurized synchronously, and the second piston plate 64 moves slightly inside the seat shell 61, so that the first roller 65 on one side of the second piston plate 64 can be pressed against the side of the guide rail 13 with greater force.

[0058] When the seat shell 61 moves above the guide rail 13, the second roller 71 in the pressure relief lubrication assembly 7 at the bottom of the seat shell 61 also rolls above the supporting cross plate 16. At this time, under the elastic force of the second spring 73, the connecting hole 74 on the side of the pin 72 is misaligned with the end side through hole 654 on the wheel seat 651. At this time, the lubricating oil inside the lower oil storage chamber 622 will not be discharged outward through the connecting pipe and the end side through hole 654. When it is necessary to add lubricating oil to the wheel 652 in the wheel seat 651, the battery box clamping and conveying mechanism 3 needs to be at the loading station. The motor 32 drives the bottom plate 31, the seat shell 61 and the pressure relief lubrication assembly 7 at the bottom of the seat shell 61 to move on the guide rail away from the test pressing mechanism 4, that is, the outer end of the loading station moves a certain distance until the second roller 71 in the pressure relief lubrication assembly 7 moves along the supporting cross plate 16 to the top of the pad plate 15, and the slope 151 at the end of the pad plate 15 plays a role in guiding the movement of the second roller 71. When the second roller 71 moves to the top of the pad strip 15, the second roller 71 will drive the pin 72 on the top to move upward, and at the same time, the connecting hole 74 on the side of the pin 72 will be aligned and connected with the end side through hole 654 on the side of the wheel seat 651, and part of the lubricating oil inside the lower oil storage chamber 622 will be applied to the surface of the wheel 652 through the end side through hole 654. The wheel seat 651 is set as an arc surface near the wheel 652. The oil leaking from the end side through hole 654 can quickly apply the lubricating oil to the surface of each group of wheels 652 with the rotation of the wheel 652, so that the first roller 65 can be quickly and evenly lubricated. Compared with the traditional method of manually adding lubricating oil, the structural linkage can realize the rapid and even application of lubricating oil on the first roller 65, with higher application efficiency, and better protection for the first roller 65 and the side of the guide rail 13.

[0059] The motor 32 drives the bottom plate 31 and the second roller 71 in the pressure relief lubrication assembly 7 at the bottom of the seat shell 61 to quickly move to the top of the pad plate 15 and then quickly move in the opposite direction to land on the supporting cross plate 16. When the second roller 71 is located above the supporting cross plate 16, under the gravity of the second roller 71 and the pin 72 itself and the elastic force of the second spring 73, the pin 72 quickly moves downward inside the guide groove 653, and the connecting hole 74 and the end side through hole 654 are quickly misaligned to block the end side through hole 654, preventing the lubricating oil inside the lower oil storage chamber 622 from leaking out. If the pressure between the first roller 65 and the side wall of the guide rail 13 is too low, resulting in insufficient friction of the damping seat 6, the first piston plate 63 can be adjusted by adjusting the adjusting bolt 67 to squeeze the lubricating oil inside the upper oil storage chamber 621, thereby increasing the friction between the first roller 65 and the guide rail 13.
