Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a bidirectional compatible probe component and a charging and discharging device. Background Art

[0002] At present, the production process of lithium-ion batteries will go through processes such as formation and capacity separation. In a series of battery preparation processes, lithium batteries need to be charged and discharged for a long or short time, which requires the use of charging and discharging equipment. The existing lithium battery production lines produce a single battery model. Although in the early stage of the construction of the charging and discharging production line, the compatibility of the probe components of the charging and discharging equipment will be considered based on the existing battery models, this compatibility range is very limited. The normal compatibility range is ±5mm, but this compatibility range cannot meet the needs of the existing charging and discharging production lines. Based on the experience of existing charging and discharging production lines, after the construction of the new production line is completed, the battery model may be changed to meet the customer's requirements for battery size. However, due to the limitations of existing equipment, the existing probe components are not compatible with the new model batteries. On this basis, a lot of manpower and material resources are needed to transform the production line, and the transformation cost is high. Utility Model Content

[0003] Based on this, in order to solve the technical problem that the probe components of current charging and discharging equipment are not highly compatible and cannot meet the needs of new battery models, resulting in high production line modification costs, the utility model provides a bidirectionally compatible probe component and charging and discharging equipment.

[0004] The utility model provides a bidirectional compatible probe assembly, which includes a mounting frame and multiple fixing plates. The multiple fixing plates are installed side by side on the mounting frame, and the distance between any two adjacent fixing plates can be adjusted.

[0005] The utility model provides a plurality of fixing plates on the mounting frame and a plurality of charging and discharging probes on each fixing plate. When the equipment is replaced, the lateral spacing between the charging and discharging probes can be adjusted by adjusting the position of the fixing plate on the mounting frame. The longitudinal spacing between the charging and discharging probes can be adjusted by adjusting the position of the charging and discharging probe on the fixing plate. The number of charging and discharging probes can also be reduced or increased to meet the annular charging and discharging requirements of the equipment. Compared with the past, the compatible range of the equipment is increased, and the function of adding and reducing the charging and discharging probes is realized.

Each transverse mounting plate has a through slot extending along its length, and multiple adjustment bolts are slidably mounted within the through slot. Each fixing plate is positioned below the two transverse mounting plates at both ends, and each fixing plate has adjustment screw holes at both ends. The multiple adjustment bolts within the through slots extend through the adjustment screw holes of the multiple fixing plates and are then tightened by multiple adjustment nuts.

The top of the charging and discharging probe is connected to a metal copper wire through an adjusting nut, and the metal copper wire is connected to a copper busbar. When the charging and discharging equipment is in operation, the probe is pressed together and the compression distance of the spring 1 is adjusted by adjusting the stroke of the cylinder to prevent the top of the charging and discharging probe from protruding. The voltage needle mainly collects the voltage value of the indentation depth on the surface of the battery pole and feeds it back to the host computer for display. The charging and discharging probe is connected to the copper busbar through the metal copper wire, and the copper busbar is connected to the external wire to form a circuit to realize the charging and discharging circuit of the lithium battery.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model provides a plurality of fixing plates on the mounting frame and a plurality of charging and discharging probes on each fixing plate.

[0028] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] Reference Figures 1-4 This embodiment provides a bidirectional compatible probe assembly, including a mounting frame and four fixing plates 1.

[0031] Four fixed plates 1 are arranged side by side at intervals. Each fixed plate 1 has a through slot 2 7 extending along its length. Six fixed bases 1 8 are spaced apart in the through slot 2 7. The fixed bases 1 8 pass through the through slot 2 7 and can slide within the through slot 2 7. The bottom of the fixed base 8 has four fixing screw holes 801 along the edge and along the circumference of the edge. The fixed base 1 8 can be detachably mounted on the fixed plate 1 through the four fixing screw holes 801 and using four adjusting bolts 2. Figure 5 Each fixed base 8 is provided with a mounting hole 1 extending through it. A charge-discharge probe 2 is provided through this hole. A voltage probe 201 is provided at the bottom of the charge-discharge probe 2. A spring 9 is sheathed around the charge-discharge probe 2. The ends of the spring 9 are connected to the fixed base 8 and the bottom of the charge-discharge probe 2, respectively. The top of the charge-discharge probe 2 extends beyond the top of the fixed base 8 and is connected to a metal copper wire 11 via a fastening nut 10. The metal copper wire 11 is connected to a copper busbar 12. Because the fixed base 8 can move within the through slot 2 7, the longitudinal distance between any two adjacent charge-discharge probes 2 on the fixed plate 1 can be adjusted. In this embodiment, there are four fixed plates 1, and the number of charge-discharge probes 2 on each fixed plate 1 is six. Of course, in other embodiments, there can be three, five, or other numbers of fixed plates 1, and the number of charge-discharge probes 2 on each fixed plate 1 can be five, eight, or other numbers. The specific number can be appropriately designed based on actual needs. In this embodiment, each fixed plate 1 is provided with adjustment screw holes 5 extending through both ends, for a total of eight adjustment screw holes 5.

[0032] The mounting frame is used to mount the fixed plate 1. In this embodiment, the mounting frame includes two transverse mounting plates 3 and four longitudinal mounting plates 19. The two transverse mounting plates 3 are positioned above the ends of the fixed plate 1 and perpendicular to the fixed plate 1. The ends of the transverse mounting plates 3 are fixed inside the storage area of ​​the charging and discharging equipment such as the chemical component storage. Both transverse mounting plates 3 are provided with a through slot 4 extending along their length. Four adjustment bolts 1 are spaced apart within the through slot 4, for a total of eight adjustment bolts 1, and the adjustment bolts 1 can slide within the through slot 4. The eight adjustment bolts 1 extend through eight adjustment screw holes 5 and are threadedly connected to eight adjustment nuts, thereby securing the ends of the fixed plate 1 to the two transverse mounting plates 3. With this structure, since the adjustment bolts 1 can slide within the through slot 4, the distance between any two adjacent fixed plates 1 can be adjusted, and thus the lateral distance between any two adjacent charge-discharge probes 2 on any two fixed plates 1 can be adjusted. The longitudinal mounting plate 19 has an inverted U-shaped structure. The four longitudinal mounting plates 19 are fixedly connected to the tops of the four fixing plates 1, respectively. The tops of the longitudinal mounting plates 19 are mounted and fixed within the storage area of ​​the charging and discharging equipment, such as the chemical component storage area, thereby securing the entire probe assembly to the charging and discharging equipment. In this embodiment, the longitudinal mounting plates 19 are also equipped with multiple vertically arranged connecting rods 20 at intervals. The bottoms of the connecting rods 20 are connected to the tops of the fixing plates 1. The provision of the connecting rods 20 enhances the mechanical strength of the overall structure of the bidirectionally compatible probe assembly of this embodiment.

[0033] Combine Figure 6-Figure 8The bidirectional compatible probe assembly of this embodiment also includes two fixing plates 2 13. The two fixing plates 2 13 are respectively arranged on one side of two of the fixing plates 1 1. Both ends of the fixing plates 2 13 are connected to connecting plates 18, and the connecting plates 18 are fixed to the fixing plates 1 1. The fixing plates 2 13 are penetrated by through slots 3 15 arranged along their length direction. Six fixing bases 2 16 are penetrated at intervals in the through slots 3 15. The fixing bases 2 16 are detachably mounted on the fixing plates 2 13 by adjusting bolts 3. Each fixing base 2 16 is penetrated by a mounting through hole 2. A temperature probe 14 is penetrated in the mounting through hole 2. The top is penetrated by multiple mounting through holes 2 of the fixing bases 2 16, and each temperature probe 14 is fitted with a spring 2 17. The two ends of the spring 2 17 are respectively connected to the fixing base 2 16 and the bottom of the temperature probe 14. In this embodiment, there are two fixing plates 2 13, and there are six temperature probes 14 on each fixing plate 2 13. Of course, in other embodiments, the number of second fixing plates 13 may be three, four, or other numbers, and the number of temperature probes 14 on each second fixing plate 13 may be five, eight, or other numbers. The specific number can be reasonably designed based on actual needs. With the above structural arrangement, since the second fixing base 16 can move within the third through-slot 15, the longitudinal distance between any two adjacent temperature probes 14 on the second fixing plate 13 can be adjusted. Furthermore, since the second fixing plate 13 is mounted on the first fixing plate 1, the position of the temperature probes 14 can also be adjusted by adjusting the position of the first fixing plate 1.

[0034] Through the above structural setting, during the equipment transformation and remodeling process, the charging and discharging probes 2 and the temperature probe 14 can be moved longitudinally at equal intervals by dismantling the fixed base 1 8 and the fixed base 2 16 to adjust the longitudinal spacing of the charging and discharging probes 2 and the temperature probe 14. At the same time, the charging and discharging probes 2 and the temperature probe 14 can be increased or decreased according to the actual remodeling requirements to meet the remodeling requirements; when adjusting the lateral spacing of the charging and discharging probes 2, the equidistant spacing can be adjusted according to the scale 6 feet; thereby realizing the longitudinal and lateral two-way adjustment of the probe assembly, and the adjustment spacing is controllable, and the adjustment range far exceeds the compatibility range of the existing charging and discharging probe 2 needle plate, which has met the various needs of the existing production line for equipment transformation.

[0035] In this embodiment, when the charging and discharging equipment is in operation, the probe is pressed together and the compression distance of the spring 9 is adjusted by adjusting the cylinder stroke to prevent the top of the charging and discharging probe 2 from protruding. The depth of the indentation on the surface of the battery pole is measured. The voltage needle 201 mainly collects the voltage value and feeds it back to the host computer for display. The charging and discharging probe 2 is connected to the copper bus 12 through the metal copper wire 11, and the copper bus 12 is connected to the external wire to form a circuit to realize the lithium battery charging and discharging circuit.
