Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a battery formation device. Background Technology

[0002] In the manufacturing process of new energy batteries, the batteries are charged through a formation device to activate their activity. During the continuous charging process, chemical reactions occur inside the battery, producing gas. If these gases are not removed in time, the battery will swell due to the pressure difference between the inside and outside, affecting the yield and reducing production capacity.

[0003] To address this, a negative pressure system is integrated into the formation equipment. Specifically, each battery is equipped with a negative pressure formation nozzle. When extracting gas, the injection hole is usually used as the exhaust port for formation. The gas discharged under negative pressure contains electrolyte, and the gaseous electrolyte will crystallize inside the nozzle after cooling.

In the past, these nozzles were installed manually one by one. The difficulties encountered were the limited installation space and the thousands of negative pressure formation nozzles, which resulted in low replacement efficiency and reduced production capacity.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] This application provides a battery formation device that solves the problem in related technologies where crystals appear on the negative pressure nozzles of battery formation devices, requiring manual installation and cleaning of each nozzle individually, or the need to import cleaning equipment for cleaning, resulting in low replacement efficiency and reduced production capacity.

[0045] See Figures 1 to 7 As shown in the figure, this application provides a battery formation apparatus, including:

[0046] The battery formation assembly 10 includes a frame 11, on which probes 12 for docking battery electrodes are provided. The probes 12 are divided into positive probes and negative probes, wherein the positive probes are used to dock the positive terminal of the battery, the negative probes are used to dock the negative terminal of the battery, and a negative pressure suction nozzle 13 is used to dock the battery filling port.

[0047] The battery formation assembly 10 performs a formation test after docking with the positive and negative terminals of the battery under test via positive and negative probes. During the formation test, a chemical reaction occurs inside the battery, generating gas. The battery formation assembly 10 integrates a negative pressure suction nozzle 13. When extracting gas, the battery liquid filling port is usually used as the venting port for the formation process.

[0048] The nozzle cleaning assembly 20 includes a cleaning nozzle 21 for cleaning the negative pressure nozzle 13. After the cleaning nozzle 21 is connected to the negative pressure nozzle 13, it uses negative pressure to suction out the electrolyte remaining on the inner wall of the negative pressure nozzle 13, thereby cleaning the negative pressure nozzle 13. The nozzle cleaning assembly 20 also includes a drive component that drives the cleaning nozzle 21 to move below the negative pressure nozzle 13 and connect with it.

[0049] The drive assembly is used to move the cleaning nozzle 21 from the cleaning station to the cleaning station where the negative pressure nozzle 13 is being cleaned. The drive assembly includes a lifting component connected to the frame 11 that drives the cleaning nozzle 21 to move up and down, and a translation component that drives the cleaning nozzle 21 to move closer to or away from the negative pressure nozzle 13. When the drive assembly moves the cleaning nozzle 21 to the cleaning station, it prevents the cleaning nozzle 21 from interfering with the normalization of the probe 12 and the negative pressure nozzle 13 during operation.

[0050] The battery formation equipment of this application embodiment integrates a nozzle cleaning component 20 on the battery formation component 10 for automatically cleaning the negative pressure nozzle 13. The nozzle cleaning component 20 performs a suction operation on the electrolyte solvent remaining in the negative pressure nozzle 13 after the cleaning nozzle 21 is connected to the negative pressure nozzle 13, thereby automatically cleaning the electrolyte solvent remaining in the negative pressure nozzle 13 and preventing it from crystallizing in the negative pressure nozzle 13.

[0051] The drive assembly is used to move the cleaning nozzle 21 to a position below the negative pressure nozzle 13 and dock with it after battery formation is complete. During battery formation, the cleaning nozzle 21 is driven away from the negative pressure nozzle 13, so that the cleaning nozzle 21 does not interfere with the normal operation of the negative pressure nozzle 13 or the probe 12. This application realizes automatic cleaning of the negative pressure nozzle 13 of the formation equipment, thereby improving production efficiency.

[0052] In some alternative embodiments: see Figures 1 to 3 As shown in the figure, this application embodiment provides a battery formation apparatus. Below the battery formation component 10 of the battery formation apparatus is a lifting platform 14 for placing a battery tray 15. The battery tray 15 is placed on the lifting platform 14. The lifting platform 14 is used to move the battery tray 15 and the batteries placed on the battery tray 15 up and down.

[0053] A first lifting mechanism 16 is provided between the lifting platform 14 and the frame 11 to drive the lifting platform 14 and the battery tray 15 to move synchronously up and down. The first lifting mechanism 16 is preferably, but not limited to, a cylinder, hydraulic cylinder, electric cylinder, or linear module, etc., and is used to drive the lifting platform 14 and the battery tray 15 to move towards or away from the negative pressure suction nozzle 13 and the probe 12. When the first lifting mechanism 16 drives the lifting platform 14 to move upward to a set height, the positive terminal, negative terminal, and battery filling port of the battery are respectively connected to the probe 12 and the negative pressure suction nozzle 13.

[0054] A guide mechanism 17 is provided between the lifting platform 14 and the frame 11 to guide the lifting movement of the lifting platform 14, and a limiting mechanism 18 to limit the lifting height of the lifting platform 14. The guide mechanism 17 is preferably, but not limited to, a cylindrical guide rod. One end of the cylindrical guide rod is fixedly connected to the frame 11, and a linear bearing that is slidably connected to the cylindrical guide rod is fixedly connected to the lifting platform 14, thereby causing the lifting platform 14 to move vertically up and down along the height direction of the cylindrical guide rod.

[0055] The limiting mechanism 18 is preferably, but not limited to, a vertical limiting rod fixed to the top of the lifting platform 14. A buffer rubber block is provided at the top of the vertical limiting rod. When the lifting platform 14 rises to the set height, the buffer rubber block at the top of the vertical limiting rod contacts the frame 11, thereby limiting the lifting platform 14 from continuing to move the battery tray upward, and preventing the probe 12 and the negative pressure suction nozzle 13 from colliding with the battery and damaging the product or equipment.

[0056] In some alternative embodiments: see Figure 4 and Figure 5As shown in the illustration, this application provides a battery formation apparatus. A first mounting plate for fixing a probe 12 and a second mounting plate for fixing a negative pressure nozzle 13 are connected to the frame 11 of the battery formation apparatus. Both the first and second mounting plates are rectangular plates of a predetermined length. The first and second mounting plates provide mounting and positioning for the probe 12 and the negative pressure nozzle 13 on the frame 11.

[0057] There are multiple probes 12, the specific number of which is determined by the number of batteries to be tested in a single formation test. One positive probe and one negative probe are required for each battery. The multiple probes 12 are arranged alternately along the length of the first mounting plate. There are multiple negative pressure nozzles 13, the specific number of which is determined by the number of batteries to be tested in a single formation test. One negative pressure nozzle 13 is required for each battery. The multiple negative pressure nozzles 13 are arranged alternately along the length of the second mounting plate.

[0058] In this embodiment, multiple probes 12 and multiple negative pressure nozzles 13 are respectively arranged and installed on the first mounting plate and the second mounting plate. When the battery formation equipment performs the formation test, several batteries can be simultaneously formed and tested at one time, realizing batch unified testing and greatly improving battery production efficiency.

[0059] In some alternative embodiments: see Figure 6 and Figure 7 As shown, this application embodiment provides a battery formation device. The lifting assembly of the battery formation device includes a third mounting plate 22 and a second lifting mechanism 23 connected to the frame 11 and driving the third mounting plate 22 to move up and down. The second lifting mechanism 23 is preferably, but not limited to, a cylinder, hydraulic cylinder, electric cylinder, or linear module.

[0060] The second lifting mechanism 23 is used to drive the cleaning nozzle 21 to move vertically up and down. When the cleaning nozzle 21 is in the cleaning state, the second lifting mechanism 23 adjusts the position height of the cleaning nozzle 21 to below the negative pressure nozzle 13, so that the position height of the cleaning nozzle 21 is lower than that of the negative pressure nozzle 13 when it is in the cleaning state. When the cleaning nozzle 21 is in the waiting-to-be-cleaned state, the second lifting mechanism 23 adjusts the position height of the cleaning nozzle 21 to above the negative pressure nozzle 13, thereby preventing the cleaning nozzle 21 from interfering with the normal operation of the negative pressure nozzle 13.

[0061] The translation assembly includes multiple swing arms 28 rotatably connected to the third mounting plate 22, and multiple cleaning nozzles 21 are provided and respectively connected to each swing arm 28. The multiple swing arms 28 are arranged sequentially and at intervals along the length of the third mounting plate 22, so that the multiple cleaning nozzles 21 respectively clean the multiple negative pressure nozzles 13. The third mounting plate 22 is also provided with a swing assembly that drives each swing arm 28 to swing synchronously on the third mounting plate 22.

[0062] Specifically, the swing assembly includes a rack 24 slidably connected to the third mounting plate 22, and driven gears 27 meshing with the rack 24 and driving each swing arm 28 to rotate. Multiple driven gears 27 are provided, each corresponding to one swing arm 28. When the rack 24 reciprocates on the third mounting plate 22, the rack 24 converts linear motion into rotational motion that drives the driven gears 27. The driven gears 27 then drive the swing arms 28 to swing through this rotational motion.

[0063] The third mounting plate 22 is also provided with a drive gear 25 that meshes with the rack 24. The drive gear 25 is connected to a rotary drive mechanism 26. The rotary drive mechanism 26 is preferably, but not limited to, a rotary cylinder, a motor, etc. The rotary drive mechanism 26 drives the drive gear 25 to rotate in both directions, thereby driving the rack 24 to slide back and forth on the third mounting plate 22, and thus synchronously driving multiple swing arms 28 to synchronously drive each cleaning nozzle 21 to swing synchronously.

[0064] The third mounting plate 22 is equipped with a linear guide rail that slides a rack 24. The rack 24 is slidably connected to the linear guide rail via a slider. The linear guide rail is fixed to the third mounting plate 22, and the slider is fixed to the rack 24, allowing the rack 24 to move along the set trajectory of the linear guide rail. Each cleaning nozzle 21 is connected to a vacuum line, which is connected to a vacuum suction device. The vacuum suction device is connected to each cleaning nozzle 21 through the vacuum line, using negative pressure vacuum to remove residual electrolyte from the negative pressure nozzle 13, achieving the purpose of cleaning.

[0065] In some alternative embodiments: see Figure 6 and Figure 7 As shown in the figure, this application embodiment provides a battery formation device. The swing assembly of the battery formation device includes a motor (not shown) or a rotary cylinder (not shown) respectively connected to a third mounting plate 22. Multiple motors or rotary cylinders are provided, and the number of motors or rotary cylinders is the same as the number of swing arms 28. The output shaft of the motor or rotary cylinder is fixedly connected to each swing arm 28. Each motor or rotary cylinder can independently control the swing state of each swing arm 28.

[0066] In some alternative embodiments: see Figure 6 and Figure 7As shown, this application embodiment provides a battery formation device. The lifting assembly of the battery formation device includes a third mounting plate 22 and a second lifting mechanism 23 connected to the frame 11 and driving the third mounting plate 22 to move up and down. The second lifting mechanism 23 is preferably, but not limited to, a cylinder, hydraulic cylinder, electric cylinder, or linear module.

[0067] The translation component includes a push plate (not shown) slidably connected to the third mounting plate 22. Multiple cleaning nozzles 21 are provided and connected to the push plate via connecting plates (not shown). The third mounting plate 22 is provided with a linear mechanism (not shown) that pushes the push plate to move the cleaning nozzles 21 closer to or further away from the negative pressure nozzle 13. The linear mechanism is preferably, but not limited to, a cylinder, hydraulic cylinder, electric cylinder, or linear module.

[0068] In some alternative embodiments: see Figures 1 to 5 As shown in the illustration, this application provides a battery formation apparatus. The probe 12 and negative pressure nozzle 13 of this apparatus are both slidably connected to the frame 11 in a vertical direction. Both the probe 12 and the negative pressure nozzle 13 are floatingly connected to the frame 11 via springs. The outlet of the negative pressure nozzle 13 is connected to a residual electrolyte cup 19. Both the cleaning nozzle 21 and the negative pressure nozzle 13 are flexible suction cups, with the lip of the cleaning nozzle 21 facing upwards and the lip of the negative pressure nozzle 13 facing downwards.
