Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a bottom tray material hopper mechanism and battery production equipment. Background Technology

[0002] Batteries are a common energy storage device. In the assembly and production process of square aluminum-cased batteries, it is usually necessary to assemble a base plate to the insulating film.

[0003] The hopper can hold multiple base plates. To ensure the accuracy of the base plate loading position, the gap between the base plate and the inner wall of the hopper is small. The base plate is lifted upward by a lifting mechanism, which facilitates the robotic arm to grasp and load the base plate. However, during the lifting process and the robotic arm's retrieval, the base plate may be squeezed against the inner wall of the hopper, causing wear. Furthermore, due to the smooth surface of the base plate, a negative pressure layer can easily form between two adjacent base plates, causing them to adhere to each other and become unable to separate during loading, affecting the loading effect. During the debugging process, it is difficult to adjust the horizontal position of the hopper, resulting in a long debugging time and a complex debugging process, leading to problems such as low base plate loading efficiency and poor loading effect. Utility Model Content

[0004] The purpose of this utility model is to provide a bottom tray material hopper mechanism and battery production equipment to solve the problems of low bottom tray material feeding efficiency and poor feeding effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, a bottom support piece hopper mechanism is connected to a lifting mechanism. The bottom support piece hopper mechanism includes: a hopper body, the hopper body including a first positioning plate, a second positioning plate, and a lifting block, the first positioning plate and the second positioning plate enclosing a hopper space for accommodating the bottom support piece; the lifting mechanism is connected to the lifting block so that the lifting block is slidably disposed inside the hopper space along a first direction; the lifting block is clearance-fitted with both the first positioning plate and the second positioning plate; an anti-slip piece device disposed at the output end of the hopper space; and an adjustment device disposed below the hopper body to adjust the position of the hopper body in a second direction and a third direction; the first direction is the thickness direction of the bottom support piece, the second direction is the length direction of the bottom support piece, and the third direction is the width direction of the bottom support piece.

[0007] Preferably, the gap between the lifting block and the first positioning plate is 0.2mm-0.5mm; and / or, the gap between the lifting block and the second positioning plate is 0.2mm-0.5mm.

[0008] Preferably, the adjustment device includes an operating table, a first adjustment plate, and a second adjustment plate. The first adjustment plate is slidably disposed on the operating table along the second direction, and the second adjustment plate is slidably disposed on the first adjustment plate along the third direction. The hopper body moves synchronously with the second adjustment plate.

[0009] Preferably, one of the first adjusting plate and the second adjusting plate is provided with a limiting block, and the other is provided with a limiting groove corresponding to the position of the limiting block, the limiting groove extending along the third direction.

[0010] Preferably, the adjusting device further includes an adjusting member, wherein the first adjusting plate has a first adjusting groove and the second adjusting plate has a second adjusting groove, and the adjusting member can be selectively connected to the first adjusting groove or the second adjusting groove to limit the position of the first adjusting plate or the second adjusting plate.

[0011] Preferably, both the first adjusting plate and the second adjusting plate are provided with through holes for the lifting mechanism to pass through, and the cross-sectional area of ​​the through holes is smaller than the cross-sectional area of ​​the lifting block.

[0012] Preferably, the anti-slip plate device includes an arc-shaped portion, the cross-sectional area of ​​which gradually increases along the direction close to the output end of the hopper space, and the arc-shaped portion is smoothly connected to the first positioning plate.

[0013] Preferably, there are two first positioning plates, which are symmetrically arranged on both sides of the lifting block along its length. There are also two anti-slip plate devices, with the arc-shaped portions of the two anti-slip plate devices facing each other.

[0014] Preferably, the output end of the hopper space is equipped with a lifting position detection sensor.

[0015] In a second aspect, a battery production apparatus includes a lifting mechanism, a wafer picking mechanism, and a bottom wafer hopper mechanism as described above, wherein the lifting mechanism is connected to the lifting block to move the lifting block along the first direction.

[0016] The beneficial effects of this utility model are:

[0017] A bottom support sheet hopper mechanism is connected to a lifting mechanism. The bottom support sheet hopper mechanism includes a hopper body, an anti-slip sheet device, and an adjusting device. The hopper body includes a first positioning plate, a second positioning plate, and a lifting block. The first positioning plate and the second positioning plate enclose a hopper space for accommodating the bottom support sheet. The lifting mechanism is connected to the lifting block so that the lifting block is slidably disposed inside the hopper space along a first direction. The lifting block is clearance-fitted with both the first and second positioning plates. The anti-slip sheet device is disposed at the output end of the hopper space. The adjusting device is disposed below the hopper body to adjust the position of the hopper body in a second direction and a third direction. The first direction is the thickness direction of the bottom support sheet, the second direction is the length direction of the bottom support sheet, and the third direction is the width direction of the bottom support sheet.

[0018] In this way, the contact between the bottom support plate and the anti-slip plate device breaks the negative pressure layer between adjacent bottom support plates, allowing the plate-grabbing mechanism to accurately clamp the top bottom support plate and achieve single-piece grabbing. Furthermore, the hopper space formed by the first positioning plate and the second positioning plate restricts the movement of the lifting block, preventing the lifting block from shifting when the lifting mechanism moves it. This allows the bottom support plate supported by the lifting block to rise stably in the first direction. The adjustment device can easily adjust the position of the hopper space in the second and third directions, improving feeding efficiency and feeding effect. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] See Figure 1This utility model provides a bottom support sheet hopper mechanism connected to a lifting mechanism (not shown in the figure). The bottom support sheet hopper mechanism includes a hopper body 1, an anti-slip sheet device 2, and an adjusting device 3. The hopper body 1 includes a first positioning plate 11, a second positioning plate 12, and a lifting block 14. The first positioning plate 11 and the second positioning plate 12 enclose a hopper space 13 for accommodating the bottom support sheet. The lifting mechanism is connected to the lifting block 14 so that the lifting block 14 is slidably disposed inside the hopper space 13 along the first direction Z. The lifting block 14 is clearance-fitted with the first positioning plate 11 and the second positioning plate 12. The anti-slip sheet device 2 is disposed at the output end of the hopper space 13. The adjusting device 3 is disposed below the hopper body 1 to adjust the position of the hopper body 1 in the second direction X and the third direction Y. The first direction Z is the thickness direction of the bottom support sheet, the second direction X is the length direction of the bottom support sheet, and the third direction Y is the width direction of the bottom support sheet.

[0030] In this embodiment, the lifting mechanism moves synchronously with the lifting block 14, enabling the lifting block 14 to move vertically along the first direction Z within the hopper space 13. The first positioning plate 11 and the second positioning plate 12 both extend along the first direction Z, causing the hopper space 13 to extend along the first direction Z, forming a channel for the lifting block 14 to move. The top of the hopper space 13 is the output end, and the piece-retrieving mechanism is located at the output end of the hopper space 13 to facilitate the removal of the bottom tray piece conveyed to the output end. The adjusting device 3 is connected to the end of the hopper body 1 that is away from the output end.

[0031] It should be noted that multiple bottom support pieces are assembled into the hopper space 13 and placed on the lifting block 14. The lifting mechanism can push the lifting block 14 upward within the hopper space 13 to the discharge end. Under the action of the anti-slip device 2, a single bottom support piece is grabbed by the piece-retrieving mechanism, while the remaining bottom support pieces are still placed on the lifting block 14, thus realizing the feeding of single bottom support pieces.

[0032] Thus, the anti-slip device 2 can abut against and break the negative pressure layer between adjacent bottom trays when the bottom tray is being fed, so that the tray picking mechanism can accurately clamp the top bottom tray, improving feeding efficiency and effect. In addition, the hopper space 13 formed by the first positioning plate 11 and the second positioning plate 12 can restrict the movement of the lifting block 14, so that the lifting block 14 can move stably along the first direction Z, preventing the lifting block 14 and the bottom tray supported by the lifting block 14 from shifting or falling off when the lifting mechanism lifts the lifting block 14. The adjustment device 3 can easily adjust the position of the hopper body 1 in the second direction X and the third direction Y, which is convenient for debugging.

[0033] See Figure 1 In some embodiments, the gap between the lifting block 14 and the first positioning plate 11 is in the range of 0.2mm-0.5mm, and the gap between the lifting block 14 and the second positioning plate 12 is in the range of 0.2mm-0.5mm.

[0034] In this embodiment, the gap between the lifting block 14 and the first positioning plate 11 can be any value between 0.2mm and 0.5mm or any range between two values, such as 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc., and the gap between the lifting block 14 and the second positioning plate 12 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0035] Thus, the lifting block 14 is fitted with the first positioning plate 11 and the second positioning plate 12 with a clearance, which can prevent the lifting block 14 from excessively rubbing or colliding with the first positioning plate 11 and the second positioning plate 12 during the movement, thereby improving the lifting stability of the base plate.

[0036] It is understandable that the gaps between the lifting block 14 and the first positioning plate 11, as well as the gaps between the lifting block 14 and the second positioning plate 12, cannot be too large. If they are too large, the first positioning plate 11 and the second positioning plate 12 will not be able to guide the movement direction of the lifting block 14. The gaps between the lifting block 14 and the first positioning plate 11, as well as the gaps between the lifting block 14 and the second positioning plate 12, cannot be too small either. If they are too small, it will affect the smooth movement of the lifting block 14 in the hopper space.

[0037] See Figure 1 In some embodiments, the adjustment device 3 includes an operating table (not shown in the figure), a first adjustment plate 31 and a second adjustment plate 32. The first adjustment plate 31 is slidably disposed on the operating table along the second direction X, and the second adjustment plate 32 is slidably disposed on the first adjustment plate 31 along the third direction Y. The hopper body 1 moves synchronously with the second adjustment plate 32.

[0038] See Figure 2 and Figure 3 In this embodiment, the cross-sectional area of ​​the first adjusting plate 31 is larger than that of the second adjusting plate 32. The first positioning plate 11 and the second positioning plate 12 are vertically arranged on the side of the second adjusting plate 32 away from the first adjusting plate 31. There are two first positioning plates 11 and four second positioning plates 12. One second positioning plate 12 is arranged on each side of one first positioning plate 11, so that the first positioning plates 11 and the second positioning plates 12 enclose a square hopper space 13. Multiple connecting grooves 111 are arranged at intervals along the first direction Z on the first positioning plate 11. Multiple U-shaped connecting holes 121 are opened on the second positioning plate 12 corresponding to the connecting grooves 111. The first positioning plate 11 and the second positioning plate 12 are detachably connected by bolts (not shown in the figure). The bolts pass through the connecting holes 121 and are threadedly connected to the connecting grooves 111.

[0039] Thus, the first positioning plate 11 and the second positioning plate 12 are detachably connected, which facilitates the assembly of the hopper body 1 according to the size of the bottom support plate. By sliding the first adjusting plate 31 along the second direction X and the second adjusting plate 32 along the third direction Y, the position of the lifting block 14 can be quickly adjusted, shortening the debugging time of the hopper body 1, simplifying the debugging process, and improving the feeding efficiency and effect of the bottom support plate.

[0040] It is understandable that the first positioning plate 11 and the second positioning plate 12 can also be detachably connected through structures such as snap-fit, or the first positioning plate 11 and the second positioning plate 12 can be fixedly connected. The connection method of the first positioning plate 11 and the second positioning plate 12 can be adjusted according to actual needs, and will not be listed in detail here.

[0041] See Figure 1 In some embodiments, one of the first adjusting plate 31 and the second adjusting plate 32 is provided with a limiting block 321, and the other is provided with a limiting groove 311 corresponding to the position of the limiting block 321. The limiting groove 311 extends along the third direction Y.

[0042] In this embodiment, the limiting block 321 is fixedly disposed on the side of the second adjusting plate 32 facing the first adjusting plate 31. The side of the first adjusting plate 31 facing the second adjusting plate 32 is correspondingly provided with a limiting groove 311, so that the limiting block 321 slides in the third direction Y within the limiting groove 311. The limiting block 321 and the limiting groove 311 are provided in a one-to-one correspondence. There are two limiting blocks 321, which are respectively disposed on both sides of the lifting block 14 in the width direction.

[0043] Thus, the limiting block 321 slides within the limiting groove 311, which can restrict the movement direction of the second adjusting plate 32, prevent the second adjusting plate 32 from shifting during movement and thus affecting the positioning accuracy. This allows the staff to adjust the position of the hopper body 1 by adjusting the second adjusting plate 32, thereby achieving precise feeding and improving the feeding efficiency and effect of the bottom support plate.

[0044] It is understandable that the number and position of the limit blocks 321 can be adjusted according to actual needs, as long as the second adjustment plate 32 can be moved stably along the third direction Y. No further details are provided here.

[0045] See Figure 1 In some embodiments, the adjusting device 3 further includes an adjusting member (not shown in the figure), a first adjusting groove 312 is provided on the first adjusting plate 31, and a second adjusting groove 322 is provided on the second adjusting plate 32. The adjusting member can be selectively connected to the first adjusting groove 312 or the second adjusting groove 322 to limit the position of the first adjusting plate 31 or the second adjusting plate 32.

[0046] In this embodiment, the adjusting component is a bolt. A plurality of holes corresponding to the first adjusting groove 312 are provided on the operating table so that the first adjusting plate 31 can be fixedly mounted on the operating table by bolts. A plurality of holes corresponding to the second adjusting groove 322 are provided on the first adjusting plate 31 so that the second adjusting plate 32 can be fixedly mounted on the first adjusting plate 31 by bolts.

[0047] In this way, the adjusting components can limit the position of the first adjusting plate 31 on the operating table and the position of the second adjusting plate 32 on the first adjusting plate 31, thereby improving the stability of the hopper body 1 and preventing the first adjusting plate 31 and the second adjusting plate 32 from shifting during the feeding process and affecting the feeding effect.

[0048] It is understandable that the adjusting component can also be a locating pin or other structure, or a cylinder connected to the first adjusting plate 31 and the second adjusting plate 32 can be set on the operating table and the first adjusting plate 31 respectively to drive the first adjusting plate 31 and the second adjusting plate 32 to move. The specific structure of the adjusting component can be adjusted according to actual needs, and will not be listed in detail here.

[0049] See Figure 1 In some embodiments, both the first adjusting plate 31 and the second adjusting plate 32 are provided with through holes (not shown in the figure) for the lifting mechanism to pass through, and the cross-sectional area of ​​the through holes is smaller than the cross-sectional area of ​​the lifting block 14.

[0050] In this embodiment, the cross-sectional area of ​​the through hole on the first adjusting plate 31 is larger than the cross-sectional area of ​​the through hole on the second adjusting plate 32, and the lifting mechanism is located below the first adjusting plate 31.

[0051] In this way, the output end of the lifting mechanism can be easily connected to the lifting block 14 through the through hole, and drive the lifting block 14 to move along the first direction Z, making the overall structure of the bottom tray material bin mechanism more compact, effectively utilizing the space below the first adjusting plate 31, avoiding interference between structures, and improving the feeding effect of the bottom tray.

[0052] See Figure 1 In some embodiments, the anti-slip device 2 includes an arc-shaped portion 21. Along the direction close to the output end of the hopper space 13, the cross-sectional area of ​​the arc-shaped portion 21 gradually increases, and the arc-shaped portion 21 is smoothly connected to the first positioning plate 11.

[0053] In this embodiment, one end of the arc-shaped portion 21 is flush with one end of the second positioning plate 12 away from the adjustment device 3, and the other end smoothly transitions with the first positioning plate 11. The cross-sectional area of ​​the arc-shaped portion 21 facing the adjustment device 3 is smaller than the cross-sectional area of ​​the end away from the adjustment device 3.

[0054] Thus, when the picking mechanism extends into the hopper space 13 to grab the topmost bottom support piece, the two ends of the bottom support piece remain in contact with the anti-slip device 2 during its ascent, and gradually bend under the guidance of the arc-shaped part 21. Due to the different deformation amounts of adjacent bottom support pieces, the negative pressure layer between the topmost bottom support piece and the bottom support piece below it is broken. The topmost bottom support piece is grabbed by the picking mechanism and moved to the outside of the hopper space 13. The bottom support pieces below it fall back into the hopper space 13 under their own gravity after losing the adsorption force with the topmost bottom support piece, thus realizing the feeding of a single bottom support piece. This avoids the bottom support pieces being unable to separate due to mutual adsorption, which affects the feeding effect, reduces damage to the bottom support pieces, and improves the feeding efficiency of the bottom support pieces. Since the side wall of the arc-shaped part 21 is smooth and smoothly transitions with the first positioning plate 11, the bottom support piece is less likely to collide or be scratched with the inner wall of the first positioning plate 11 or the inner wall of the arc-shaped part 21 during the process guided by the arc-shaped part 21, thus improving the feeding effect of the bottom support piece.

[0055] It is understood that the anti-slip device 2 can be integrally formed with the first positioning plate 11 or can be detachably set with the first positioning plate 11. The connection method between the anti-slip device 2 and the first positioning plate 11 can be adjusted according to actual needs, and will not be listed in detail here.

[0056] See Figure 1 In some embodiments, two first positioning plates 11 are symmetrically arranged on both sides of the lifting block 14 along its length, and two anti-slip plate devices 2 are correspondingly provided, with the arc-shaped portions 21 of the two anti-slip plate devices 2 facing each other.

[0057] In this embodiment, four second positioning plates 12 are symmetrically arranged on both sides of the lifting block 14 in the width direction.

[0058] In this way, the anti-slip device 2 can perform anti-slip treatment on each bottom tray piece grabbed by the tray picking mechanism, so as to prevent adjacent bottom tray pieces from adsorbing each other and affecting the feeding effect.

[0059] It is understood that the anti-slip plate device 2 can also be set on the second positioning plate 12, and only one anti-slip plate device 2 can be set, which is sufficient to break the negative pressure layer between adjacent bottom support plates. In this embodiment, the anti-slip plate device 2 is symmetrically set at both ends of the bottom support plate in order to make the force at both ends of the bottom support plate more uniform and improve the feeding effect. The setting position and number of anti-slip plate devices 2 can be adjusted according to actual needs, and will not be listed in detail here.

[0060] See Figure 1 and Figure 4 In some embodiments, a lifting position detection sensor (not shown in the figure) is provided at the output end of the hopper space 13.

[0061] In this embodiment, the arc-shaped part 21 of the anti-slip device 2 is provided with a detection groove 211, and the lifting position detection sensor is set in the detection groove 211. The lifting position detection sensor and the lifting mechanism are connected to each other through the control module. When the lifting position detection sensor detects that the bottom support piece has been lifted to the position, the control module controls the lifting mechanism to stop lifting so that the piece-grabbing mechanism can grab the top bottom support piece.

[0062] Thus, by setting up a lifting position detection sensor, the lifting block 14 can be prevented from being over-lifted or under-lifted, so that the lifting block 14 can lift the bottom tray to the target position, so that the tray grabbing mechanism can grab the top bottom tray and make the bottom tray pass through the arc-shaped part 21 of the anti-slip tray device 2, realizing single-piece grabbing, avoiding mutual adsorption due to the negative pressure layer between adjacent bottom trays, and improving the feeding effect.

[0063] It is understandable that the lifting position detection sensor can be a photoelectric sensor, a proximity sensor, a pressure sensor, etc. The specific type of lifting position detection sensor can be adjusted according to actual needs. It is sufficient to detect whether the lifting block 14 and the base plate it supports have been lifted into position. No further examples will be listed here.

[0064] See Figure 1 This utility model also provides a battery production equipment, including a lifting mechanism, a wafer picking mechanism, and a bottom wafer hopper mechanism. The lifting mechanism is connected to a lifting block 14 so that the lifting block 14 can move along a first direction Z. In this embodiment, the wafer picking mechanism is a robotic arm equipped with a vacuum suction cup.

[0065] It is understandable that the lifting mechanism can be a cylinder or a linear drive mechanism such as a linear motor. The specific structure of the lifting mechanism and the plate-taking mechanism can be adjusted according to actual needs, as long as they can move synchronously with the lifting block 14 along the first direction Z. Not much will be listed here.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
