Description

Battery formation device and dial structure thereof

Technical Field

The present invention relates to a battery formation device and a dial structure thereof, and more particularly, to a dial structure including a detachable module and a battery formation device having the dial structure.

Background

A battery is an energy conversion and storage device that converts chemical or physical energy into electrical energy by reaction, i.e., a chemical source of electrical energy. The battery consists of two electrochemical active electrodes with different components, which are respectively composed of positive and negative electrodes, and the two electrodes are soaked in an electrolyte capable of providing a medium conduction function. When the anode and the cathode are connected to an external carrier, the chemical energy in the carrier is converted to provide electric energy. However, after the battery is manufactured, the physical and chemical properties of the electrode are not in the best applicable state, so the positive and negative electrode materials need to be activated by charging and discharging to improve the comprehensive performance of the battery, such as charging and discharging performance, self-discharging performance, storage performance and the like, and the process of activating the positive and negative electrode materials is called formation during the charging and discharging.

The existing battery formation system is mostly formed by matching and combining a base for bearing a battery, positive and negative electrode probes, a dial for bearing the probes, a temperature detection sensor and a negative pressure module. The quantity of the probes and the temperature detecting sensor and the distance between the elements are designed according to the quantity of the batteries to be detected arranged on the base and the distance between the batteries. However, as the size and specification of the battery are changed, the number of the batteries and the distance between the batteries in the battery formation system may be changed, but the conventional dial has a single specification, so that the position of the probe on the dial and the distance between the probes cannot be changed in accordance with the number of the batteries or the distance between the batteries, and thus a manufacturer needs to newly manufacture a dial of another specification, and further, the manufacturing cost of the dial is high, and the compatibility of the dial is low.

Disclosure of Invention

In view of the above problems, the present invention discloses a battery formation device and a dial structure thereof, which is helpful for solving the problem that the spacing between the probe position and the probe cannot be changed in accordance with the number of batteries or the battery spacing due to a single-specification dial.

The invention discloses a dial structure for carrying a probe for testing a battery, which comprises a bearing frame and at least two channel modules. The two channel modules are detachably arranged on the bearing frame in a way that the spacing distance between the two channel modules is adjustable, and the two channel modules are arranged in parallel.

The invention also discloses a battery formation device, which comprises the dial structure, at least two probes and a base for bearing a battery. The bearing frame of the dial structure is arranged on the base, and the two probes are respectively arranged on the two channel modules of the dial structure.

According to the needle dial structure and the battery formation device disclosed by the invention, the two channel modules are detachably arranged on the bearing frame in a manner that the spacing distance between the two channel modules is adjustable. When the number, specification or the distance between the batteries supported on the base is changed, a user can detach the channel module to adjust the distance between the two channel modules, and reinstall the channel module to the supporting frame after the distance is adjusted to meet the requirement. Therefore, the configuration of the channel module is beneficial to enabling the probes arranged on the channel module to be in good contact with the positive and negative electrodes of the battery or the temperature detection metal gasket. The needle dial structure can be used for adjusting the spacing distance between two channel modules at will according to the number of batteries, the specifications of the batteries or the distance between the batteries, so that the needle dial structure can be used for formation procedures of the batteries with various specifications or various arrangement configurations, and further has the advantages of reducing the cost, improving the universality and the like.

The foregoing summary of the invention, as well as the following detailed description of the embodiments, is provided to illustrate and explain the principles and spirit of the invention, and to provide further explanation of the invention as claimed.

Detailed Description

The detailed features and advantages of the present invention are described in detail in the embodiments below, which are sufficient for anyone skilled in the art to understand the technical contents of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by anyone skilled in the art according to the disclosure of the present specification, the protection scope of the claims and the attached drawings. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.

Please refer to fig. 1A to fig. 1C. Fig. 1A is a schematic perspective view of a battery formation apparatus according to an embodiment of the present invention. Fig. 1B is an exploded view of the battery formation device of fig. 1A. Fig. 1C is a schematic side view of the battery formation device of fig. 1A. In the present embodiment, the battery formation apparatus 1 includes a base 10, a needle plate structure 20, and a plurality of probes 30. The number of probes 30 is not intended to limit the present invention.

The base 10 is, for example but not limited to, a plastic frame, and has a carrying surface 110 at the bottom. The carrying surface 110 is formed with a plurality of positioning grooves (not shown), and the battery 2 to be formed can be disposed in the positioning grooves and carried on the carrying surface 110.

The dial structure 20 includes a carrier frame 210, a plurality of channel modules 220, and a plurality of spacers 230. The supporting frame 210 includes a frame 211 and a guiding rod 212. The frame 211 is provided on the base 10, and the frame 211 has two inner side surfaces 211a facing each other. The guide rod 212 is provided in the frame 211, and the guide rod 212 extends from one of the inner side surfaces 211a to the other inner side surface 211a along the normal direction N of the inner side surface 211 a. In the present embodiment, opposite ends of the guide rod 212 are fixed to the two inner side surfaces 211a, respectively.

The number of the channel modules 220 is the same as the number of the cells 2 to be formed, and the number of the channel modules 220 may be changed according to the increase or decrease of the number of the cells 2 to be formed. The channel modules 220 respectively have a first through hole 221, and the guide rod 212 penetrates through the first through hole 221 so that the channel module 230 is disposed on the supporting frame 210. The spacers 230 have a second through hole 231, and the guiding rod 212 is disposed through the second through hole 231, so that the spacers 230 are disposed on the supporting frame 210. In the embodiment, the channel module 220 and the spacer 230 are disposed on the frame 211 of the supporting frame 210 by the guiding rod 212, but the invention is not limited thereto. In other embodiments, the carrier frame does not have a guide rod, but the frame body of the carrier frame forms two sliding grooves on the inner side wall, and the two opposite ends of the channel module and the spacing block are respectively arranged in the two sliding grooves.

As shown in fig. 1A and 1C, each cell 2 to be formed has a thickness T1, a distance D1 is provided between two adjacent cells 2 to be formed, and the channel modules 220 and the spacers 230 are arranged in parallel between two inner side surfaces 211A in a staggered manner, that is, a spacer 230 is provided between each two channel modules 220. Each channel module 220 has a thickness S1, each spacer block 230 has a thickness S2, and the distance between each two channel modules 220 is exactly equal to the thickness S2 of the spacer block 230. In the present embodiment, the sum of the thicknesses of the channel modules 220 and the spacers 230 ([ the number of channel modules 220 ] × S1+ [ the number of spacers 230 ] × S2) is exactly equal to the spacing S3 between the two inner side surfaces 211 a. Therefore, all the channel modules 220 and the spacers 230 can be arranged closely in the area surrounded by the frame 211, and the relative position of the channel modules 220 or the spacers 230 is prevented from being shifted. In addition, each of the spacers 230 of the present embodiment is locked to the frame 211 of the frame 210, so as to avoid the problem that the channel module 220 cannot be well constrained due to the manufacturing tolerance of the spacers 230.

The probes 30 are, for example but not limited to, electrode probes or temperature detecting probes, which are respectively disposed on the channel modules 220. In detail, the channel modules 220 respectively have a top surface 222, and the channel modules 220 are recessed from the top surface 222 to form an accommodating space 223. The probe 30 is accommodated in the accommodation space 223 and penetrates through the through hole of the top surface 222 of the channel module 220 to contact with the positive and negative electrodes of the battery 2 to be formed or the temperature detecting metal gasket. The accommodation space 223 helps accommodate the probe 30 to prevent the entire volume of the channel module 220 carrying the probe 30 from becoming excessively large.

In this embodiment, the battery formation device 1 may further include other components required for battery formation, such as, but not limited to, a negative pressure vent pipe, a battery fluid injection pipe, and a suction nozzle. In addition, the size and shape of the channel module 220 and the spacer block 230 shown in fig. 1A to 1C are not intended to limit the present invention.

Fig. 1C shows an arrangement of the channel modules 220 and the spacers 230 in the dial structure 20, but the invention is not limited thereto. When the size of the battery or the distance between two batteries is changed, the user can adjust the number or arrangement of the channel modules 220 and the spacers 230 according to the change. Fig. 2 is a schematic side view of the battery formation device of fig. 1A with different cell pitches. Fig. 3 and 4 are schematic side views of the battery formation device of fig. 1A carrying batteries of different specifications.

As shown in fig. 2, a plurality of cells 2 to be formed are carried on the carrying surface 110 of the base 10, and the distance D2 between two cells 2 to be formed is greater than the distance D1 in fig. 1C, so that the configuration of the channel module 220 and the spacer 230 in fig. 1C cannot allow the probe 30 to contact the positive and negative electrodes of the two cells 2 to be formed or the temperature detecting metal gasket, and therefore, the arrangement of the channel module 220 and the spacer 230 needs to be adjusted to smoothly perform the cell forming process. First, the user can detach the channel module 220 and the spacer block 230 from the guide rod 212. Then, the arrangement of the channel modules 220 and the spacers 230 is changed to adjust the number of the spacers 230 between two of the channel modules 220, so that the distance between the two channel modules 220 is relatively proper, and the probes 30 disposed on the two channel modules 220 can contact the positive and negative electrodes of the two batteries 2 to be formed or the temperature sensing metal gasket. In fig. 2, 5 spacers 230 are disposed between the two channel modules 220, so that the two channel modules 220 are spaced apart from each other by a distance exactly equal to 5 times the thickness S2 of the spacers 230, and the other channel modules 220 are spaced apart from each other by a distance equal to 1 time the thickness S2 of the spacers 230.

As shown in fig. 3, the battery to be formed 2 is removed from the base 10 and a plurality of batteries to be formed 3 having different specifications from the battery to be formed 2 are placed instead. Each cell 3 to be formed has a thickness T2, and the thickness T2 is greater than the thickness T1 in fig. 1C. As such, the arrangement of the channel module 220 and the spacer 230 in fig. 1C does not allow the probe 30 to contact the positive and negative electrodes of the battery 3 to be formed or the temperature detecting metal gasket. In this case, the user can detach the channel modules 220 and the spacers 230 and adjust the number of the spacers 230 between each two channel modules 220 so that the distance between each two channel modules 220 is suitable for the probe 30 to contact the positive and negative electrodes of the battery 3 to be formed or the temperature sensing metal gasket. In fig. 3, 3 spacer blocks 230 are disposed between every two channel modules 220, so that every two channel modules 220 are spaced apart by a distance exactly equal to 3 times the thickness S2 of the spacer blocks 230.

As shown in fig. 4, the base 10 carries a plurality of to-be-formed batteries 4 having different specifications from those of the to-be-formed batteries 2 and 3. Each cell 4 to be formed has a thickness T3, and two adjacent cells 3 to be formed have a distance D3 therebetween. Thickness T3 is less than thickness T1 in fig. 1C and thickness T2 in fig. 2, and spacing D3 is less than spacing D1 in fig. 1C. In this case, the user can detach the channel module 220 and the spacer 230, and move the channel module 220 to make the channel modules 220 close enough to each other, so that the probe 30 can contact the positive and negative electrodes of the battery 4 to be formed or the temperature detecting metal gasket. In fig. 4, since the proper spacing distance between each two channel modules 220 is less than the thickness S2 of a single spacer block 230, the space between the channel modules 220 cannot accommodate any spacer block 230, and thus all of the spacer blocks 230 are removed. In other words, the dial structure 20 of fig. 4 does not have the spacer 230 on the guide rod 212.

In summary, in the battery formation device and the dial structure disclosed in the present invention, the two channel modules are detachably disposed on the carrying frame in a manner that the distance between the two channel modules is adjustable. When the number, specification or the distance between the batteries supported on the base is changed, a user can detach the channel module to adjust the distance between the two channel modules, and reinstall the channel module to the supporting frame after the distance is adjusted to meet the requirement. Therefore, the configuration of the channel module is beneficial to enabling the probes arranged on the channel module to be in good contact with the positive and negative electrodes of the battery or the temperature detection metal gasket. The needle dial structure can be used for adjusting the spacing distance between two channel modules at will according to the number of batteries, the specifications of the batteries or the distance between the batteries, so that the needle dial structure can be used for formation procedures of the batteries with various specifications or various arrangement configurations, and further has the advantages of reducing the cost, improving the universality and the like.

In addition, in one embodiment, the spacing distance between the two channel modules is adjusted by placing one or more spacer blocks between the two channel modules. Therefore, the spacing blocks can fill the gaps among the channel modules, and the size of the spacing distance is maintained.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
