Description

Technical Field

[0001] The present invention relates to the field of battery manufacturing, and in particular to a square lithium battery capacity conversion device. Background Art

[0002] In the production process of prismatic lithium batteries, both formation and capacity grading are important. Formation can activate the battery activity, ensuring its performance and lifespan, while capacity grading can reduce the short board effect after the battery is assembled. Currently, battery formation and capacity grading equipment uses multiple sets of probe modules to test the prismatic batteries in the tray. To maximize the use of the equipment, batteries of different models and sizes are usually used. This requires adjusting the distance between the probe modules to ensure compatibility of the equipment. In addition, when components such as the probe module are damaged and require repair, in order to not affect the utilization rate of the equipment, the probe module needs to be removed from the equipment and replaced with a new spare module to meet continuous production.

The "first" and "second" used are only used to distinguish names and do not represent specific quantities and orders.

[0067] like Figures 1 to 9 As shown, a preferred embodiment of a square lithium battery capacity conversion device according to the present invention.

[0068] like Figure 1 and Figure 2As shown, a square lithium battery capacity conversion device includes: a top frame mechanism 3, a bottom frame mechanism 2, a lifting and positioning mechanism 4, a tray material frame 5 and a probe module 1; the top frame mechanism 3 is connected to the bottom frame mechanism 2, the probe module 1 is detachably connected to the top frame mechanism 3, the lifting and positioning mechanism 4 is arranged above the bottom frame mechanism 2, and the tray material frame 5 is placed on the bottom frame mechanism 2; wherein, the probe module 1 includes a module frame 110, a sliding assembly 120, a positive probe assembly 130 and a negative probe assembly 140, the sliding assembly 120 includes a slide rail 121 and a slider 122 adapted to the slide rail 121, the slide rail 121 is connected to the module frame 110; the slider 122 is connected to the positive probe assembly 130 and the negative probe assembly 140.

[0069] When the equipment is running, the external equipment sends the pallet material frame 5 into the bottom frame mechanism 2 for positioning, confirms that the pallet material frame 5 is accurately positioned left and right in the bottom frame mechanism 2, and the pallet material frame 5 is placed on the pallet support guide of the bottom frame mechanism 2 when it is in the waiting state, and the power mechanism 320 drives the lifting and positioning mechanism 4 to move upward and position the pallet material frame 5 front and back once, that is, the pallet material frame 5 is placed on the lifting and positioning mechanism 2 when it is in the working state, and the lifting and positioning mechanism 4 continues to drive the pallet material frame 5 to move upward, and uses the asymmetric positioning pin 415 to perform secondary positioning and anti-reverse detection on the pallet material frame 5. After the secondary positioning is successful, it continues to lift upward until the probe, suction nozzle and other components in the integrated probe module 1 mechanism contact the battery, and then the battery process flow is carried out. After the process is completed, the power mechanism 320 reverses to reset the equipment, and the external equipment takes the pallet material frame 5 out to the next process. If the secondary positioning fails, the power mechanism 320 reverses to reset the equipment, and the external equipment takes the pallet material frame 5 out to the manual processing position.

[0070] In a preferred embodiment, reference Figure 3 and Figure 4 The module frame 110 of the probe module 1 includes a module top plate 111 and a guide fixing plate 112, and the guide fixing plate 112 is connected to both sides of the module top plate 111; the guide fixing plate 112 is also connected to a plurality of guide wheels 113, and the plurality of guide wheels 113 are arranged in sequence along the depth direction of the probe module 1; the two ends of the slide rail 121 are connected to the guide fixing plate 112; the positive probe assembly 130 includes a positive probe support plate 132 and a positive probe 131 connected to the positive probe support plate 132, and the positive probe support plate 132 is connected to the slider 122; the negative probe assembly 140 includes a negative probe support plate 142 and a negative probe 141 connected to the negative probe support plate 142, and the negative probe support plate 142 is connected to the slider 122.

[0071] The probe module 1 includes a temperature probe assembly 150 and a negative pressure docking assembly 160. The temperature probe assembly 150 includes a probe mounting seat 152 and a temperature probe 151 connected to the probe mounting seat 152. The probe mounting seat 152 is connected to the slider 122. The negative pressure docking assembly 160 includes a negative pressure mounting seat 162 and a negative pressure nozzle 161 connected to the negative pressure mounting seat 162. The negative pressure mounting seat 162 is connected to the slider 122. The temperature probe assembly 150 and the negative pressure docking assembly 160 slide on the module frame 110 via the slider 122. The probe mounting seat 152 has a connector 153, which connects the probe mounting seat 152 to the negative probe support plate 142.

[0072] Both ends of the module frame 110 are provided with slide rails 121; the probe module 1 also includes a transverse slide groove 123, and the probe module 1 includes multiple transverse slide grooves 123, and the transverse slide grooves 123 are arranged in parallel with the slide rails 121; the module frame 110 is provided with transverse slide grooves 123 at both ends and the middle. The transverse slide groove 123 is an aluminum profile, and there is a slide groove on the transverse slide groove 132. There are multiple waist-shaped holes on the positive probe support plate 132, the negative probe support plate 142, the probe mounting seat 152 and the negative pressure mounting seat 162. The locking screw is inserted into the slide groove of the transverse slide groove 132 through the waist-shaped hole. When the battery is replaced, the locking screw is loosened, and the position change of the probe assembly, negative pressure assembly, etc. can be completed without completely removing the screw. After moving, it is locked, and the probe assembly, negative pressure assembly, etc. cannot move anymore. The multiple waist-shaped holes on the positive probe support plate 132, the negative probe support plate 142, the probe mounting seat 152 and the negative pressure mounting seat 162 facilitate fine-tuning of the positive probe assembly 130, the negative probe assembly 140, the temperature probe assembly 150 and the negative pressure docking assembly 160 in the depth direction of the probe module.

[0073] A scale 124 is provided on the transverse sliding grooves 123 set at both ends of the module frame 110, and a pointer 125 is provided on the positive probe support plate 132, the negative probe support plate 142, the probe mounting seat 152 and the negative pressure mounting seat 162, and the pointer 125 points to the scale 124.

[0075] Both the positive probe assembly 130 and the negative probe assembly 140 consist of a probe support plate with a pointer 125 fixed at each end. The tip of pointer 125 is aligned with the probe position, allowing for direct adjustment based on battery size without the need for secondary calculations. The probes are arranged on the probe support plate according to the number of channels. The probes are connected to the power module 170 via a braided cord, effectively resolving the problem of poor contact between the probe and the battery caused by factors such as the bend radius of the power cable and gravity when connecting the probes directly to the battery. The difference between the positive probe assembly 130 and the negative probe assembly 140 lies in the different fixing directions of the braided cord.

[0076] The temperature probe assembly 150 consists of a probe mount 152, on which temperature probes 151 are arranged according to the number of channels. The probes 151 are then connected to the negative electrode probe support plate 142 using connectors 153. Connectors 153 have two horizontal holes to allow the temperature probes 151 to be adjusted to accommodate changes in position during battery configuration changes.

[0077] The negative pressure docking assembly 160 is composed of a negative pressure mounting base 162 with pointers 125 fixed at both ends. The tip of pointer 125 is aligned with the negative pressure nozzle 161, allowing for direct adjustment based on battery size without requiring secondary calculations.

The negative pressure cup and the welded confluence pipe are fixed by a negative pressure hose and a branch pipe buckle nut. The confluence pipe outlet is fixed to the externally connected negative pressure main pipe using a confluence pipe buckle nut. The negative pressure suction nozzle 161 is separated from the negative pressure liquid storage confluence assembly 180, which solves the problem of low space utilization in traditional integrated designs and is more suitable for integrated modules. The negative pressure cup is made by injection molding the negative pressure cup cover and the cup cover pipe joint, and then the negative pressure cup body and the cup body pipe joint. They are ultrasonically welded (or hot-melt) together, and then the pipe buckle nut is screwed on.

The pneumatic combination of an induction check valve, exhaust throttle valve, and cylinder used as the power mechanism 320 ensures stable contact pressure between the probe and the battery during operation. A cylinder adapter plate is installed at the rear of the cylinder, allowing for easier disassembly and assembly when the cylinder reaches its lifespan or needs replacement due to damage.

[0084] The limiting mechanism 330 consists of a limiting flange seat, a locking nut, and a limiting screw. The limiting flange seat is equipped with an observation port and scale lines, and multiple sets of limiting mechanisms 330 on the equipment can be quickly adjusted according to the position of the scale lines, greatly shortening the changeover time. The anti-loosening nut is used to lock the screw in place, which can effectively prevent the limiting screw from loosening.

[0091] The lifting and positioning mechanism 4 uses a lifting frame 410 that is formed in one step as the main body, which can better ensure the positioning accuracy of the positioning pin 415 and the guide position; a reflective sticker is set on the front side, and before the external device sends the pallet material frame 5 into the device, the sensor installed on the external device re-tests whether the lifting and positioning mechanism 4 is in a normal state, and then sends it into the device after re-testing and confirmation, which can further solve the problem of the battery and related structural parts being crushed due to the malfunction of the delivery device; the pallet material frame 5 has completed one positioning in the left and right directions before the lifting and positioning mechanism 4 moves, and the lifting and positioning mechanism 4 moves upward. During the process, the front guide plate 413 and the rear limiting guide plate 414 of the tray complete the primary positioning in the front-to-back direction, and then the two diagonal positioning pins 415 complete the secondary positioning and asymmetric anti-reverse detection. The front side of the heat dissipation component 411 is fixed with a downward buckle, which allows the fan assembly to be pulled out from the rear for maintenance without stopping the entire line, thereby improving the efficiency of the entire line. The fan of the heat dissipation component 411 is arranged directly below the tray material frame 5 and evenly arranged corresponding to the batteries. During the charging and discharging process, it can dissipate heat from the batteries, making the battery charging and discharging more uniform and avoiding capacity differences caused by battery temperature differences. At the same time, a line cover is set at the routing position to effectively prevent the cooling fan cable from being corroded by the electrolyte.

[0092] The pallet frame 5 is composed of a pallet base, side panels, end panels, a pallet liner, and battery spacers. The pallet base features asymmetric locating pin holes to ensure relative positioning of the batteries within the device and prevent them from reversing. The pallet frame 5 is constructed from high-temperature, corrosion-resistant insulating materials and connected with stainless steel fasteners, effectively protecting it from the high temperatures and electrolytes of the formation process. A simple combination of a liner and spacers limits the battery's position. Even with a single battery size change, flexible production is achieved by replacing only a single component, addressing the high cost of pallets for highly flexible production lines.

[0093] Combine Figure 9 The equipment also includes a fire sprinkler pipe 6, which includes multiple high-pressure pipes 610 and atomizing nozzles 611; the fire sprinkler pipe 6 is connected to the support column 212, and the height of the fire sprinkler pipe 6 is the same as the probe height.

[0094] The number of atomizing nozzles 611 can be flexibly changed according to actual needs to ensure the initial fire protection effect of lithium batteries. Fire sprinkler pipe 6

[0095] The use of high-pressure resistant pipe 610 and compression joints facilitates pipeline installation after equipment assembly, and can adapt to the internal fire-fighting needs of various equipment with different structural complexities. At the same time, it reduces manual labor while ensuring pressure resistance. The nozzle adopts atomizing nozzle 611, which is compatible with various fire-fighting media such as liquid water, gaseous perfluorohexanone, and gaseous carbon dioxide.

[0096] The equipment provided by the present invention is used in processes such as negative pressure formation, capacity division, and load adjustment of square batteries. When the equipment is running, the external equipment sends the tray material frame 5 (battery carrier) into the tray positioning mechanism for positioning, confirming that the tray material frame 5 is accurately positioned left and right in the bottom frame mechanism 2 once, and the power mechanism 320 drives the lifting positioning mechanism 4 to move upward and positions the tray material frame 5 front and back once, and the lifting positioning mechanism 4 continues to move upward, and uses the asymmetric positioning pin 415 to perform secondary positioning and anti-reverse detection on the tray material frame 5. After the secondary positioning is successful, it continues to lift upward until the probe, suction nozzle and other components in the integrated probe module 1 contact the battery, and then the battery process flow is carried out. After the process is completed, the power mechanism 320 reverses to reset the equipment, and the external equipment takes out the tray material frame 5 to the next process. If the secondary positioning fails, the power mechanism 320 reverses to reset the equipment, and the external equipment takes out the tray material frame 5 to the manual processing position.

[0097] First, the stepless adjustment of various mechanisms and the convenient pull-out design of the modules enhance the equipment's flexible production capabilities, resolving the relatively difficult maintenance and model change issues of traditional equipment. Furthermore, the integration of power module 170 and probe module 1 reduces power loss in the equipment's high-power cables and improves the equipment's charging and discharging efficiency. The positive probe assembly 130, negative probe assembly 140, temperature probe assembly 150, negative pressure docking assembly 160, power module 170, and negative pressure liquid storage manifold assembly 180 can be configured to meet the process requirements of different steps, such as formation, volume separation, and load adjustment, allowing for flexible and interchangeable use to meet diverse needs.

[0098] The equipment consists of an integrated probe module 1, a bottom frame mechanism 2, a top frame mechanism 3, a lifting and positioning mechanism 4, a pallet material frame 5, and a fire sprinkler pipe 6. The bottom frame mechanism 2 and the top frame mechanism 3 constitute the main body of the equipment. The integrated probe module 1 slides, positions, and locks on the top frame mechanism 3. The lifting and positioning mechanism 4, driven by a power mechanism 320 within the top frame mechanism 3, drives the pallet material frame 5 up and down. The equipment components used in the three processes are highly standardized and can be flexibly used interchangeably between different processes, significantly reducing equipment repair and maintenance costs for enterprises.
