Technical Field

[0001] The present application relates to the technical field of battery production, and in particular to a calibration device and battery production equipment. Background Art

[0002] During the battery production and processing, there is a process that requires batches of batteries to be stably placed on corresponding workstation slots so that subsequent processing steps such as liquid injection, helium inspection, and formation can be carried out on the batches of batteries.

[0003] In the related art, when the battery enters the work slot, there is a problem of inaccurate insertion, which makes it difficult for the battery to normally complete the corresponding processing steps in the work slot, affecting the processing quality and production efficiency of the battery. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides a correction device and a battery production device, wherein the correction device can correct the position of the battery on the corresponding station slot so that the battery remains horizontal relative to the station slot, thereby improving the processing quality and production efficiency of the battery.

[0005] In a first aspect, the present application provides a calibration device, comprising:

[0006] A correction assembly, comprising a base and a plurality of correction units arranged on the base at intervals along a preset direction, wherein the correction units include at least two pressure heads at the same height;

[0007] A driving mechanism is connected to the base, and the driving mechanism drives the base to move so that the pressing head on each correction unit presses the battery on the corresponding station slot to a horizontal state.

[0008] The calibration device according to the first aspect of the present application has at least the following beneficial effects:

[0009] When the correction device of the present application corrects the position of the battery on the work station slot, the driving mechanism drives the base to move in the direction close to the work station slot, so that the base drives all the correction units thereon to move in the direction close to the corresponding work station slot, so that the pressure head on the correction unit contacts the inclined battery on the corresponding work station slot, and presses the inclined battery to a horizontal state relative to the work station slot, so that the batteries on all the work station slots are in a stable horizontal state, thereby realizing the position correction of batch batteries, so that the batteries on all the work station slots can accurately and smoothly complete subsequent processing steps such as liquid filling, helium inspection, and formation, thereby improving the processing quality and production efficiency of the batteries.

[0010] In some embodiments, the pressure head has a flexible portion for contacting the battery.

[0011] With such a configuration, the flexible portion can buffer the battery when the pressure head corrects the tilted battery on the work station slot to a horizontal state, thereby protecting the battery top cover, reducing the risk of hard damage or friction damage to the battery top cover, and maintaining the stability of the battery structure.

[0012] In some embodiments, the correction unit further comprises a mounting plate disposed on the base, and all of the pressure heads on the correction unit are arranged on the mounting plate at intervals along a direction perpendicular to the preset direction.

[0013] With such arrangement, the pressing head aligned with the tilted portion of the battery can accurately press the tilted portion of the battery relative to the station slot, so that the positions of the batteries on different station slots can be corrected.

[0014] In some embodiments, the distance between two adjacent correction units along a preset direction can be adjusted.

[0015] Such a setting can achieve adaptation to different battery processing production lines and batteries of different specifications and sizes, thereby improving the compatibility and versatility of the correction device.

[0016] In some embodiments, a slide groove extending along a preset direction is provided on the base, and all the correction units are slidably installed in the slide groove.

[0017] With such arrangement, the distance between any two correction units can be adjusted so that the arrangement of all correction units on the base is consistent with the distribution of batteries in all station slots.

[0018] In some embodiments, the correction device further includes a first sensor disposed on the base, and the first sensor is configured to detect the parallelism between the base and the workstation slot when the base moves.

[0019] This arrangement makes it convenient for the operator to monitor and adjust the connection status between the drive mechanism and the base and the installation status of the base itself in real time, adjust the parallelism between the base and the work station slot to within a preset value range, keep the base and the work station slot relatively parallel, and accurately and stably correct the battery position on the work station slot.

[0020] In some embodiments, the calibration device further includes a second sensor disposed on the base, and the second sensor is configured to detect a position of the base relative to the workstation slot when the base moves.

[0021] Such an arrangement keeps the displacement of the base within a controllable range, reduces the probability of structural damage due to excessive pressing of the battery by the pressing head, and further improves the accuracy and stability of battery position correction.

[0022] In some embodiments, there are two driving mechanisms, and the two driving mechanisms are respectively connected to the two ends of the base.

[0023] With such an arrangement, the synchronous action of the two driving mechanisms can make the movement of the base more stable, reduce the risk of tilting of the base during movement, and further improve the accuracy and stability of battery position correction.

[0024] In a second aspect, an embodiment of the present application provides a battery production device, wherein the battery production device includes the correction device described above.

[0025] The battery production equipment according to the second aspect of the present application has at least the following beneficial effects:

[0026] The battery production equipment of the present application therefore also has the same technical effect brought by the correction device, that is, it can press the inclined batteries on the work station slots to a horizontal state relative to the work station slots, so that the batteries on all the work station slots are in a stable horizontal state, thereby realizing the position correction of batch batteries, so that the batteries on all the work station slots can accurately and smoothly complete subsequent processing steps such as liquid filling, helium inspection, formation, etc., thereby improving the processing quality and production efficiency of the batteries.

[0027] In some embodiments, the battery production equipment further includes a conveying platform, on which a plurality of workstation slots for placing batteries are provided at intervals along the preset direction.

[0028] With such an arrangement, after a batch of batteries to be processed are placed on the corresponding workstation slots on the conveyor table, the conveyor table can transport the batch of batteries thereon to the corresponding position correction station so that the correction device can perform position correction on the batch of batteries, so that the batteries on all the workstation slots can accurately and smoothly complete subsequent processing procedures, thereby improving the processing quality and production efficiency of the batteries.

[0038] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0042] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0043] The battery is composed of one or more battery cells. For each battery, the battery cells that make up the battery can be connected in series, in parallel, or in mixed connection. Mixed connection means that the battery cells are connected in series and in parallel.

[0044] The battery cell is the smallest unit that makes up the battery, and in the structure of the battery cell, it includes a shell, an electrolyte and an electrode assembly. The electrode assembly is a component in the battery cell where the electrochemical reaction occurs, and the electrode assembly includes a positive electrode sheet, a negative electrode sheet and a diaphragm. The shell is a structure with one end open and a hollow interior. The electrode assembly is arranged inside the shell, and the end cover is arranged at the opening of the shell. The internal environment of the battery cell is formed by covering the opening with the end cover at the opening. Of course, the end cover and the shell can also be integrated. Specifically, the end cover and the shell can form a common connection surface before other components are put into the shell, and when the interior of the shell needs to be encapsulated, the end cover is covered with the shell. The shell can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell can be determined according to the specific shape and size of the electrode assembly. The material of the shell can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose special restrictions on this.

[0045] During the battery production and processing, there is a process that requires batches of batteries to be stably placed on corresponding workstation slots so that subsequent processing steps such as liquid injection, helium inspection, and formation can be carried out on the batches of batteries.

[0046] In the related art, a robot is generally used to clamp multiple batteries at the same time and place them in the corresponding work slots. Since the robot clamp is a moving part, it is difficult to ensure the accuracy of each battery. As a result, the battery is tilted relative to the work slot after being placed, and the battery cannot remain horizontal relative to the work slot, making it difficult to complete the subsequent processing of the battery normally, affecting the processing quality and production efficiency of the battery.

[0047] For example, when the battery in the corresponding work station slot is being injected with liquid, if the battery top cover is tilted relative to the work station slot, when the injection equipment moves down to inject liquid into the battery, the injection nozzle of the injection equipment cannot be effectively connected with the injection port on the top of the battery, causing the injection nozzle of the injection equipment to collide with other parts of the battery top cover and be damaged, resulting in electrolyte spraying out of the injection nozzle, thereby causing contamination of the battery surface and affecting the injection quality of the battery. At the same time, the electrolyte sprayed on the battery surface will also increase the workload of manual cleaning of the battery appearance, affecting the battery production efficiency.

[0048] In order to address the problem that batteries are currently not accurately positioned when entering a work station slot, which makes it difficult for the batteries to normally complete the corresponding processing steps on the work station slot, thereby affecting the processing quality and production efficiency of the batteries, a correction device is provided in one or more embodiments of the present application, wherein a correction component and a drive mechanism are provided, and the drive mechanism drives multiple correction units on the correction component to move, so that the correction device as a whole can perform position correction on the batteries on the battery processing production line, so that the batteries on the work station slots on the battery processing production line can accurately and smoothly complete subsequent processing steps such as liquid injection, helium inspection, and formation, thereby improving the processing quality and production efficiency of the batteries.

[0049] See also Figure 1 and Figure 2 The present application provides a correction device, which includes a correction component 100 and a driving mechanism 200.

[0050] The calibration assembly 100 includes a base 110 and a plurality of calibration units 120 arranged on the base 110 at intervals along a preset direction X. The calibration unit 120 includes at least two pressing heads 121 at the same height.

[0051] The driving mechanism 200 is connected to the base 110 , and the driving mechanism 200 drives the base 110 to move so that the pressing head 121 on each correction unit 120 presses the battery on the corresponding station slot 510 to a horizontal state.

[0052] It should be noted that, in the calibration device of the present application, the base 110 may be a frame structure, or a regular or irregular plate structure, without specific limitation.

[0053] The preset direction X corresponds to the arrangement direction of all the station slots 510 on the battery processing production line, so that all the correction units 120 on the base 110 can correspond to all the station slots 510 one by one. For example, in one embodiment, all the station slots 510 on the battery processing production line are distributed along a straight line, and correspondingly, the preset direction X is a straight line, that is, a plurality of correction units 120 are arranged on the base 110 at intervals along the straight line. In another embodiment, all the station slots 510 on the battery processing production line are distributed along an arc line, and correspondingly, the preset direction X is an arc line, that is, a plurality of correction units 120 are arranged on the base 110 at intervals along the arc line.

[0054] That the correction unit 120 includes at least two pressure heads 121 at the same height can be understood as follows: ends of all pressure heads 121 on the correction unit 120 are on the same horizontal line or plane.

[0055] In addition, it should be noted that in the correction device of the present application, the drive mechanism 200 can be configured as a linear drive such as a pneumatic cylinder, an electric cylinder, a ball screw mechanism, a linear slide module, etc., so that the drive mechanism 200 drives the base 110 to move, so that the base 110 drives all the correction units 120 thereon to move. Of course, the drive mechanism 200 can also be configured as a manual drive, such as a linear drive mechanism with a rocker and a lifting platform, so that the operator can manually operate the drive mechanism 200 according to the actual needs of the battery processing production line, so as to realize the action of the base 110 driving all the correction units 120 thereon to move.

[0056] It can be understood that when the correction device of the present application performs position correction on the battery in the work station slot 510, the driving mechanism 200 drives the base 110 to move in the direction close to the work station slot 510, so that the base 110 drives all the correction units 120 thereon to move in the direction close to the corresponding work station slot 510, so that the pressure head 121 on the correction unit 120 contacts the inclined battery on the corresponding work station slot 510, and presses the inclined battery to a horizontal state relative to the work station slot 510, so that the batteries on all the work station slots 510 are in a stable horizontal state, thereby realizing the position correction of batch batteries, so that the batteries on all the work station slots 510 can accurately and smoothly complete subsequent processing steps such as liquid filling, helium inspection, and formation, thereby improving the processing quality and production efficiency of the batteries.

[0057] See also Figure 1 and Figure 2 In some embodiments of the present application, the pressure head 121 has a flexible portion 1211 for contacting the battery 900 .

[0058] Specifically, the pressure head 121 is rod-shaped, and the flexible part 1211 is made of elastic material such as polyurethane, rubber, and plastic. The flexible part 1211 is detachably arranged at the end of the pressure head 121 by bonding, sleeve connection, etc. to facilitate the disassembly, assembly and replacement of the flexible part 1211.

[0059] It can be understood that when the base 110 drives the correction unit 120 thereon to move toward the direction close to the corresponding work station slot 510, the flexible portion 1211 on the pressure head 121 on the correction unit 120 contacts the battery top cover. In this way, the flexible portion 1211 can buffer the battery during the process in which the pressure head 121 corrects the tilted battery on the work station slot 510 to a horizontal state, thereby protecting the battery top cover, reducing the risk of hard damage or friction damage to the battery top cover, and maintaining the stability of the battery structure.

[0060] In other embodiments, the flexible portion 1211 can be constructed in a dot shape, a spherical shape or a circular block shape, and the flexible portion 1211 protrudes relative to the end of the pressure head 121. In this way, the contact area between the pressure head 121 and the battery top cover can be reduced, thereby reducing the friction between the pressure head 121 and the battery top cover, further reducing the risk of the battery top cover being hard damaged or frictionally damaged.

[0061] See also Figure 3 and Figure 4 In some embodiments of the present application, the correction unit 120 further includes a mounting plate 122 disposed on the base 110, and all the pressure heads 121 on the correction unit 120 are spaced apart on the mounting plate 122 along a direction perpendicular to the preset direction X.

[0062] Specifically, the battery on the station slot 510 is a square shell battery. The base 110 is plate-shaped, and the preset direction X is the length direction of the base 110. The mounting plate 122 is vertically arranged with the base 110, and the correction unit 120 includes two pressing heads 121, which are respectively arranged at opposite ends of the mounting plate 122 and aligned with the opposite ends of the station slot 510 up and down.

[0063] It can be understood that when the battery in the work station slot 510 is in a tilted state, one end of the battery will be higher than the other end of the battery, that is, the top of the battery will be tilted relative to the work station slot 510. Based on this, the base 110 drives all the correction units 120 thereon to move toward the direction close to the corresponding work station slot 510 under the power of the driving mechanism 200, so that a pressing head 121 on the mounting plate 122 will contact the part of the battery that is tilted relative to the work station slot 510. As the base 110 moves, the pressing head 121 can completely press the battery into the work station slot 510, thereby keeping the battery level with the work station slot 510.

[0064] Since the positions of the batteries on different work station slots 510 that are tilted relative to the work station slots 510 are different, when the base 110 drives the correction unit 120 thereon to move toward the direction close to the corresponding work station slot 510, the pressing head 121 aligned with the tilted position of the battery above and below can accurately press the tilted position of the battery relative to the work station slot 510, so that the positions of the batteries on different work station slots 510 can all be corrected.

[0065] See also Figure 1 and Figure 2 In some embodiments of the present application, along a preset direction X, the distance between two adjacent correction units 120 can be adjusted.

[0066] It should be noted that batteries of different sizes have different lengths and widths, and different overall shapes, such as square batteries, cylindrical batteries, etc. Correspondingly, the shapes and sizes of the station slots 510 used to support and place batteries on the battery processing production line are also different.

[0067] In addition, on all the workstation slots 510 of the battery processing production line, the robot will selectively place the batteries to be processed in the preset workstation slots 510 according to the actual production needs and operation settings. For example, only one workstation slot 510 of two adjacent workstation slots 510 has a battery placed in it, and the other workstation slot 510 is idle.

[0068] Based on the above situation, the present application sets the spacing between two adjacent correction units 120 along the preset direction X in an adjustable manner, so that the operator can adjust the spacing between two adjacent correction units 120 according to the spacing on all the station slots 510 of the actual battery processing production line, the distribution of batch batteries in all the station slots 510, and the specifications and sizes of the batteries, so that the arrangement of all the correction units 120 on the base 110 is consistent with the distribution of batteries in all the station slots 510, so that the correction units 120 on the base 110 accurately correspond to the batteries in the station slots 510. In this way, the adaptation to different battery processing production lines and batteries of different specifications and sizes is achieved, and the compatibility and versatility of the correction device are improved.

[0069] Further, see Figure 3 and Figure 4 A slide groove 111 extending along a preset direction X is provided on the base 110 , and all the correction units 120 are slidably installed in the slide groove 111 .

[0070] Specifically, the mounting plate 122 of the correction unit 120 is slidably embedded in the sliding groove 111 through a slider to maintain the stability of the correction unit 120 as a whole on the base 110 .

[0071] When it is necessary to adjust the distance between any two correction units 120, the operator can directly push the mounting plate 122 so that the mounting plate 122 drives all the pressure heads 121 thereon to slide along the slide groove 111, and thus adjust the distance between any two correction units 120 so that the arrangement of all the correction units 120 on the base 110 is consistent with the distribution of the batteries in all the station slots 510. Under the power of the driving mechanism 200, the correction unit 120 on the base 110 can press the tilted and raised batteries on the corresponding station slots 510 to a horizontal state, thereby accurately realizing the position correction of batch batteries, so that the batteries on all the station slots 510 can accurately and smoothly complete subsequent processing procedures such as liquid injection, helium inspection, and formation, thereby improving the processing quality and production efficiency of the batteries.

[0072] Of course, in other embodiments, a plurality of first connection holes (not shown in the figure) are provided on the slide slot 111, and second connection holes (not shown in the figure) corresponding to the first connection holes are provided on the mounting plate 122, and the first connection holes are detachably connected to the second connection holes through fasteners (not shown in the figure). Specifically, the first connection holes and the second connection holes are both configured as threaded holes, and the fasteners are fastening bolts or screws.

[0073] When the position of the mounting plate 122 is slidably adjusted to the preset position on the slide slot 111, the corresponding first connecting hole on the slide slot 111 and the second connecting hole on the mounting plate 122 can be connected and fixed by fasteners, so as to lock the position of the mounting plate 122 and realize the overall fixation of the correction unit 120, thereby reducing the risk of the correction unit 120 slipping relative to the base 110 when correcting the position of the battery on the corresponding workstation slot 510, and improving the accuracy and stability of the battery position correction.

[0074] In some embodiments of the present application, see Figure 1 and Figure 2 The calibration device further includes a first sensor 300 disposed on the base 110 , and the first sensor 300 is configured to detect the parallelism between the base 110 and the workstation slot 510 when the base 110 moves.

[0075] Specifically, the base 110 and the work station slot 510 are both regular cube or column structures. The first sensor 300 may be, but is not limited to, an inclination sensor, a parallelism measuring instrument, etc., and the base 110 has at least two first sensors 300 to improve the accuracy of detection. An alarm (not shown in the figure) is also provided on the base 110, and the alarm is electrically connected to the first sensor 300 and the driving mechanism 200. The alarm may be, but is not limited to, a buzzer, an audible and visual alarm, etc., that is, the alarm can achieve the alarm effect by emitting a buzzer and / or an easily identifiable color light.

[0076] It should be noted that when the parallelism between the base 110 and the work station slot 510 exceeds the preset value, if the base 110 continues to drive all the correction units 120 thereon to move toward the work station slot 510 on the battery processing production line, the pressure head 121 on the correction unit 120 will find it difficult to accurately contact and press-fit the inclined battery on the corresponding work station slot 510.

[0077] Based on this, the present application sets a first sensor 300 on the base 110. When the base 110 drives all the correction units 120 thereon to move toward the work station slot 510 on the battery processing production line under the power of the driving mechanism 200, the first sensor 300 detects the parallelism between the base 110 and the work station slot 510 in real time. When the parallelism between the base 110 and the work station slot 510 exceeds the preset value, the alarm emits an alarm signal such as a buzzer. At the same time, the driving mechanism 200 stops moving. At this time, the operator can detect and adjust the connection status between the driving mechanism 200 and the base 110 and the installation status of the base 110 itself, and adjust the parallelism between the base 110 and the work station slot 510 to within the preset value range, so that the base 110 and the work station slot 510 remain relatively parallel. In this way, the battery position correction on the work station slot 510 can be accurately and stably corrected.

[0078] In some embodiments of the present application, see Figure 1 and Figure 2 The calibration device further includes a second sensor 400 disposed on the base 110 , and the second sensor 400 is configured to detect the position of the base 110 relative to the workstation slot 510 when the base 110 moves.

[0079] Specifically, the second sensor 400 is a displacement sensor, such as a grating sensor, an induction synchronizer, etc.

[0080] It can be understood that when the base 110 drives all the correction units 120 thereon to move toward the work station slot 510 on the battery processing production line under the power of the driving mechanism 200, the second sensor 400 detects the position of the base 110 relative to the work station slot 510 in real time, that is, it detects the position of the pressure head 121 on the correction unit 120 relative to the base 110 in real time, so that the displacement of the base 110 is within a controllable range, reducing the probability of the battery being over-pressed by the pressure head 121 and structural damage, and further improving the accuracy and stability of the battery position correction.

[0081] See also Figure 1 In some embodiments of the present application, there are two driving mechanisms 200, and the two driving mechanisms 200 are respectively connected to the two ends of the base 110 for driving.

[0082] Specifically, the driving mechanism 200 can be, but is not limited to, a linear drive such as a pneumatic cylinder, an electric cylinder, a ball screw mechanism, a linear slide module, etc., so that the driving mechanism 200 drives the base 110 to move, so that the base 110 drives all the correction units 120 thereon to move.

[0083] The correction device of the present application respectively sets two driving mechanisms 200 at both ends of the base 110. The synchronous operation of the two driving mechanisms 200 can make the movement of the base 110 more stable, reduce the risk of tilting of the base 110 during movement, and further improve the accuracy and stability of battery position correction.

[0084] In addition, see Figure 1 and Figure 2 , an embodiment of the present application also provides a battery production device, the battery production device includes the above-mentioned correction device.

[0086] The battery production equipment of the present application, since it is equipped with the above-mentioned correction device, also has the same technical effect brought by the correction device, that is, it can press the inclined batteries on the work station slots 510 to a horizontal state relative to the work station slots 510, so that the batteries on all the work station slots 510 are in a stable horizontal state, thereby realizing the position correction of batch batteries, so that the batteries on all the work station slots 510 can accurately and smoothly complete subsequent processing steps such as liquid filling, helium inspection, formation, etc., thereby improving the processing quality and production efficiency of the batteries.

[0087] Furthermore, in some embodiments of the present application, the battery production equipment further includes a conveying platform 500 , on which a plurality of workstation slots 510 for placing batteries are provided at intervals along a preset direction X.

[0088] Specifically, the conveying platform 500 is a conveyor belt, and the trajectory of the conveyor belt can be, but is not limited to, a straight line, an arc, a circular ring, etc., and is not specifically limited.

[0089] It is not difficult to understand that after the robot places the batch of batteries to be processed on the corresponding workstation slots 510 on the conveyor table 500, the conveyor table 500 then conveys the batch of batteries thereon to the corresponding position correction station so that the correction device can perform position correction on the batch of batteries, so that the batteries on all the workstation slots 510 can accurately and smoothly complete the subsequent processing steps, thereby improving the processing quality and production efficiency of the batteries.
