Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a pressure-applying and probe-automatic positioning device compatible with the charging and discharging of different blade batteries. Background Technology

[0002] Currently, the global energy transition and the new energy vehicle industry are developing rapidly. As a core component, the production technology of power batteries is crucial. Blade batteries, with their high safety and other advantages, are widely used. However, their ultra-long, thin-film structure presents challenges to downstream processes such as capacity testing. During capacity testing and charging / discharging, the battery expands and deforms due to electrochemical reactions. If the battery tray and the batteries on it are not effectively restrained, quality problems or even thermal runaway may occur. Therefore, applying appropriate clamping force is critical. However, current industry-standard capacity testing fixture systems have significant drawbacks: poor versatility (due to variations in blade battery size, existing fixtures lack adaptation mechanisms, leading to cumbersome changeovers); low pressure control precision (traditional methods lack precise control and real-time feedback); and insufficient capacity to cope with expansion (rigid fixtures cannot adaptively adjust, making it difficult to achieve "constant pressure" restraint and providing continuous, stable, and uniform protection).

[0022] The following is a reference appendix. Figure 1-7 This application describes a pressurization and probe automatic positioning device compatible with the charging and discharging of different blade batteries.

[0023] A pressure-applying and probe-automatic positioning device compatible with charging and discharging of different blade batteries, such as... Figure 1 As shown, the device includes a mounting base plate 1, a tray support mechanism 2 connected to the mounting base plate 1, and a restraint and pressurization mechanism 3 connected to the mounting base plate 1. The restraint and pressurization mechanism 3 is located on both sides of the tray support mechanism 2 in the first direction X to restrain and fix the battery tray and the battery on the battery tray. A probe positioning and pressing mechanism 4 is connected to the mounting base plate 1 and is located on both sides of the tray support mechanism 2 in the second direction Y. The probe positioning and pressing mechanism 4 is provided with probes 42313 that are connected to the battery. The probe positioning and pressing mechanism 4 positions the battery on the battery tray and aligns the battery terminals on the battery with the probes 42313. Specifically, the battery tray is fixed on the tray support mechanism 2, the restraint and pressurization mechanism 3 clamps the battery tray and the battery on it, and then positions it with the probe positioning and pressing mechanism 4, and finally makes the probes 42313 accurately connected to the battery terminals, so that the device is compatible with the positioning, pressurization and charging and discharging of different types of blade batteries.

[0024] As a preferred option, such as Figure 2 As shown, the probe positioning and pressing mechanism 4 includes a pushing mechanism 41, which is fixedly connected to the mechanism mounting base plate 1. A probe group adjustment mechanism 42 is slidably connected to the pushing mechanism 41. The probe 42313 is located on the probe group adjustment mechanism 42. The pushing mechanism 41 drives the probe group adjustment mechanism 42 to move in the first direction X. Specifically, the pushing mechanism 41 drives the probe group adjustment mechanism 42 to perform a clamping movement relative to the mechanism mounting base plate 1, so that the probe 42313 is precisely aligned with the battery terminal of the battery on the battery tray.

[0025] As a preferred option, such as Figure 2 As shown, an over-width detection mechanism 5 is provided between the propulsion mechanisms 41 to measure whether the battery tray is over-width.

[0026] As a preferred option, such as Figure 2 As shown, the propulsion mechanism 41 includes a slide rail base 411 and a drive cylinder 412. Both the slide rail base 411 and the drive cylinder 412 are fixedly connected to the mechanism mounting base plate 1. A mechanism slide plate 413 is slidably connected to the slide rail base 411. The mechanism slide plate 413 is screwed and fixed to the probe group adjustment mechanism 42. The piston end of the drive cylinder 412 is fixedly connected to the probe group adjustment mechanism 42 to drive the probe group adjustment mechanism 42 to move in the first direction X. Specifically, the drive cylinder 412 serves as the power source of the propulsion mechanism 41. The probe group adjustment mechanism 42 moves relative to the mechanism mounting base plate 1 in the first direction X under the action of the drive cylinder 412 through the sliding guide structure formed by the slide rail base 411 and the mechanism slide plate 413.

[0027] As a preferred option, such as Figure 3 As shown, the probe group adjustment mechanism 42 includes a frame 421, which is screwed to a mechanism slide plate 413. The frame 421 is fixedly connected to a drive cylinder 412. A linear guide rail 422 in the second direction Y is provided on the frame 421. A probe group positioning mechanism 423 and a first guide mechanism 424 are slidably connected on the linear guide rail 422. The probe 42313 is located on the probe group positioning mechanism 423. A first spring 425 is connected between the first guide mechanism 424 and the probe group positioning mechanism 423, so that the first guide mechanism 424 drives the probe group positioning mechanism 423 to position the battery tray and battery terminal. Specifically, the movement of the first guide mechanism 424 drives the probe group positioning mechanism 423 to move in the second direction Y through the first spring 425. The first spring 425 is used to adjust the gap between the first guide mechanism 424 and the probe group positioning mechanism 423 to match the structure of the battery tray, thereby facilitating the positioning of the probe group positioning mechanism 423.

[0028] As a preferred option, such as Figure 3 and Figure 4As shown, the first guiding mechanism 424 includes a guide plate 4241, which is slidably connected to a linear guide rail 422. The guide plate 4241 is connected to the probe group positioning mechanism 423 via a first spring 425. An adjusting cylinder 4242 is fixedly connected to the frame 421. The piston end of the adjusting cylinder 4242 is fixedly connected to the guide plate 4241 to drive the guide plate 4241 to slide along the linear guide rail 422 in the second direction Y, thereby driving the probe group positioning mechanism 423 to slide along the linear guide rail 422 in the second direction Y. Specifically, the first guiding mechanism 424 adjusts the gap between the first guiding mechanism 424 and the probe group positioning mechanism 423 by driving the guide plate 4241 through the adjusting cylinder 4242. A guide cylinder 4243 is fixedly connected to the upper part of the guide cylinder 4243. A first guide block 4244 is fixedly connected to the piston end of the guide cylinder 4243. A guide rod 4245 in the first direction X is provided between the first guide block 4244 and the guide plate 4241, so that the first guide block 4244 moves in the first direction X. The first guide block 4244 matches the end structure of the battery tray, thereby assisting the probe group positioning mechanism 423 in positioning the battery tray and the battery terminal. Specifically, under the action of the guide cylinder 4243, the first guide block 4244 moves in the first direction X and is engaged above the battery tray, so that the first guide block 4244 is in close contact with the end structure of the battery tray on the side near the battery, thereby realizing the gap positioning of the probe group positioning mechanism 423.

[0029] As a preferred option, such as Figure 3 and Figure 5 As shown, the probe group positioning mechanism 423 includes multiple single probe positioning mechanisms 4231, all of which are slidably connected to the linear guide rail 422. Adjacent single probe positioning mechanisms 4231 are connected by a second spring 4232. Each single probe positioning mechanism 4231 is provided with a probe 42313. Specifically, the multiple single probe 42313 mechanisms are arranged on the linear guide rail 422, and adjacent single probe 42313 mechanisms are connected by a second spring 4232. When the first guide block 4244 moves in the first direction X and is engaged above the battery tray, the second spring 4232 between the single probe positioning mechanisms 4231 also extends during the movement of the guide plate 4241 driven by the adjusting cylinder 4242, so that each single probe positioning mechanism 4231 reaches a suitable position, thereby aligning each single probe positioning mechanism 4231 with each blade battery on the battery tray.

[0030] As a preferred option, such as Figure 3 and Figure 5As shown, the single probe positioning mechanism 4231 includes a single probe mounting plate 42311, which is slidably connected to a linear guide rail 422. Adjacent single probe mounting plates 42311 are connected by a second spring 4232. A flexible guide mechanism 42312 and a probe 42313 are provided on the single probe mounting plate 42311. The flexible guide mechanism 42312 has a positioning notch 42314, which matches the structure of the battery tray. The probe 42313 is aligned with the battery on the battery tray through the positioning notch 42314. Specifically, when the first guide block 4244 moves in the first direction X and is engaged above the battery tray, the gap between the single probe positioning mechanisms 4231 has been pulled to a suitable position by the second spring 4232. At this time, the drive cylinder 412 moves in the first direction X, and the single probe positioning mechanism 4231 is precisely aligned through the positioning notch 42314 of the flexible guide mechanism 42312 under the action of the drive cylinder 412, so that the battery terminal on the battery tray is precisely aligned with the probe 42313, thereby achieving precise pressing between the battery terminal and the probe 42313.

[0031] As a preferred option, such as Figure 5 As shown, the flexible guiding mechanism 42312 includes a connecting rod 100. One end of the connecting rod 100 is fixedly connected to a limiting block 200, and the other end of the connecting rod 100 away from the limiting block 200 is fixedly connected to a second guiding block 300. A positioning notch 42314 is located on the second guiding block 300. A first sliding hole 400 is provided on the single probe mounting plate 42311. The first sliding hole 400 is slidably connected to the connecting rod 100. A third spring 500 is sleeved on the connecting rod 100. The third spring 500 is located between the second guiding block 300 and the single probe mounting plate 42311, thereby realizing the extension, retraction and reset of the flexible guiding mechanism 42312 relative to the single probe mounting plate 42311. The probe 42313 is connected to the single probe mounting plate 42311 via a sliding plate 600. The single probe mounting plate 42311 has a sliding groove 700, which is installed on the sliding plate 600. The sliding plate 600 has a second sliding hole 800, which is slidably connected to the probe 42313. The probe 42313 is fitted with a fourth spring 900 and a fifth spring 1000. The fourth spring 900 is located between the head end of the probe 42313 and the sliding plate 600, and the fifth spring 1000 is located between the tail end of the probe 42313 and the sliding plate 600. This allows the probe 42313 to extend, retract, and return relative to the single probe mounting plate 42311. The sliding groove 700 is a long groove, and the sliding plate 600 can be adjusted up and down within the sliding groove 700 to facilitate installation and debugging by personnel.

[0032] As a preferred option, such as Figure 2 and Figure 5As shown, the two flexible guide mechanisms 42312 at the beginning and the two flexible guide mechanisms 42312 at the end can be set to be longer than the other flexible guide mechanisms 42312, so as to facilitate the precise alignment of all flexible guide mechanisms 42312.

[0033] As a preferred option, such as Figure 3 As shown, a fixed handle 426 is provided at one end of the frame 421, and a current adapter plate 427 is provided on the frame 421. The current line of the probe 42313 is installed on the current adapter plate 427. Specifically, by loosening the bolts between the frame 421 and the mechanism slide plate 413, the operator can directly pull out the frame 421 through the fixed handle 426 for maintenance.

[0034] As a preferred option, such as Figure 6 As shown, the mounting base plate 1 and the tray support mechanism 2 are connected by a flexible sliding member 21 to buffer the battery tray when the restraint and pressure mechanism 3 restrains it, preventing damage to the battery tray. A bracket 22 is fixedly connected to the flexible sliding member 21, and a limit plate 23 is provided on the bracket 22 to limit the edge of the battery tray. A positioning pin 24 is provided on the bracket 22, which matches the pin hole of the battery tray. A micro switch 25 is provided on the bracket 22 to detect the position of the battery tray. Optionally, the flexible sliding member 21 can be a damping slide rail to achieve the buffering effect; it can also be a slide rail and slider cooperation structure with a spring, specifically: the slide rail has a limit structure at both ends, a slider is slidably connected to the slide rail, the slide rail is fixedly connected to the mounting base plate 1, the slider is fixedly connected to the bracket 22, and a spring is connected between the slider and the limit structure, thereby achieving the buffering effect between the slide rail and the slider through the spring.

[0035] As a preferred option, such as Figure 7As shown, the restraint and pressurization mechanism 3 includes a pressurization support mechanism 31 and a support plate 32. Both the pressurization support mechanism 31 and the support plate 32 are fixedly connected to the mechanism mounting base plate 1. A drive motor 33 and two symmetrically arranged lead screws 34 are fixedly connected to the pressurization support mechanism 31. The drive motor 33 is driven by the two lead screws 34 to drive the lead screws 34 to rotate. The sliders of the two lead screws 34 are fixedly connected to the same drive plate 35. A limiting rod 36 in the second direction Y is provided between the support plate 32 and the pressurization support mechanism 31. The drive plate 35 is slidably connected to the limiting rod 36. A top head 37 is fixedly connected to the drive plate 35 to abut against the battery on the battery tray. The restraint and pressurization mechanism 3 includes a blocking mechanism 38. The blocking mechanism 38 is fixedly connected to the mechanism mounting base plate 1. A blocking cylinder 381 is provided on the top of the blocking mechanism 38. A pressure plate 382 is fixedly connected to the piston end of the blocking cylinder 381, and a blocking plate 383 is fixedly connected to the pressure plate 382. The blocking plate 383 is used to abut against the battery tray. Specifically, after the battery tray is loaded, it is fixed on the tray support mechanism 2. Under the action of the blocking cylinder 381, the pressure plate 382 and the blocking plate 383 fall to the same height as the battery tray. Then, under the drive of the drive motor 33, the lead screw 34 moves, thereby causing the drive plate 35 to move. The drive plate 35 constrains and pressurizes the battery in the battery tray through the top head 37 in the second direction Y. The battery tray first presses against the blocking plate 383, and then the batteries in the battery tray are gradually pressurized to a suitable gap. The probe positioning and pressing mechanism 4 then starts to operate. After the probe 42313 completes its work, the constraining and pressing mechanism 3 gradually resets.

[0036] Preferably, the same drive source is used in the restraint and pressurization mechanism 3, so that the pressurization pressure is uniform and synchronous, effectively avoiding battery damage or inaccurate positioning caused by bias. At the same time, two symmetrical left-hand and right-hand lead screws 34 are used to generate pressure in the same direction. The pressure acts entirely on the center line of the battery, ensuring the stability of the pressurization process and resisting the huge force generated during the pressurization process. Furthermore, the drive plate 35 is a double-layer plate, and the two layers are fixedly connected by a pressure sensing mechanism, thereby realizing the motor-driven movement of the lead screw 34. At the same time, in conjunction with the pressure sensing closed-loop control system, the closed-loop control system can apply and accurately control the restraint pressure on the battery in real time.

[0037] In one specific embodiment, this utility model is used to restrain a battery tray with a convex V-shaped structure. Blade batteries are installed on the battery tray, and the diagonal pin holes of the battery tray are aligned with the positioning pins 24 on the bracket 22. Simultaneously, the four corners of the battery tray are limited and fixed by the limiting plates 23. Under the action of the blocking cylinder 381, the pressure plate 382 and the blocking plate 383 fall to the same height as the battery tray. Then, driven by the drive motor 33, the lead screw 34 moves, thereby causing the drive plate 35 to move. The drive plate 35, in the second direction Y, restrains and pressurizes the batteries in the battery tray through the top head 37. The battery tray first presses against the blocking plate 383, and then the batteries in the battery tray are gradually pressurized to a suitable gap. At this time, the adjusting cylinder 4242 drives the guide plate 4241 to move in the second direction Y. The first guiding mechanism 424 and the probe group... The gap between the positioning mechanisms 423 is opened to a suitable position, and at the same time, the gap between the single probe positioning mechanisms 4231 in the probe group positioning mechanism 423 is also opened to a suitable position. At this time, the guide cylinder 4243 drives the first guide block 4244 to extend into the battery tray, so that the first guide block 4244 is close to the battery side and tightly attached to the first convex V-shaped structure at the end of the battery tray. Then, under the action of the drive cylinder 412, the positioning notch 42314 with a V-shaped notch on the single probe positioning mechanism 4231 is inserted into the convex V-shaped structure on the battery tray and cooperates, guiding the single probe mounting plate 42311 so that the probe 42313 can be accurately aligned with the battery terminal. As the flexible guide mechanism 42312 is continuously compressed, the probe 42313 is pressed onto the battery terminal to work. After the probe 42313 completes its work, the device is reset in sequence.

[0038] This invention overcomes the problem of poor versatility of existing capacity-matching fixtures, enabling quick and easy switching of blade battery models and providing flexible positioning functionality with probe 42313.

[0039] This invention provides a high-precision, real-time adjustable pressure restraint mechanism to adapt to the optimal process pressure requirements of different battery models.

[0040] This invention dynamically suppresses battery expansion throughout the entire charging and discharging process, maintaining stable and uniform restraint force, thereby greatly improving safety and the quality of the finished battery.

[0041] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
