Description

Technical Field

[0001] This utility model relates to the field of new energy technology, and in particular to a shell transfer device and battery production equipment. Background Technology

[0002] Before assembly, the steel casings of cylindrical batteries need to be fed into a feeding device and subjected to sequential operations such as inspection, flipping, and dust removal. To improve feeding efficiency, the feeding device in this technology uses a whole-tray picking method to retrieve the steel casings from the tray. However, the steel casings picked from the whole tray are arranged in multiple rows on the feeding device, which is not conducive to the smooth execution of inspection, flipping, and dust removal operations, nor is it convenient for the next process. Therefore, it is necessary to consolidate the multiple rows of steel casings into a single row. Utility Model Content

[0003] Therefore, it is necessary to provide a casing transfer device and battery production equipment that can form a single row of casings into a single row to address the above problems.

[0004] A housing transfer device, comprising:

[0005] A conveying assembly has an inlet end and an outlet end spaced apart along a preset direction, the conveying assembly being capable of carrying and conveying the housing along the preset direction; and

[0006] The shaping assembly includes a baffle and a drive member. The baffle is configured to form a shaping channel that extends along the preset direction and allows the housing to pass through. The shaping channel narrows from the inlet end to the outlet end. The drive member can drive the baffle to vibrate.

[0007] In one embodiment, a gap is formed between the bottom edge of the retaining edge and the bearing surface of the conveying assembly.

[0008] In one embodiment, each of the flanges is rotatable about an axis perpendicular to the bearing surface of the conveying assembly.

[0009] In one embodiment, the position of each of the drive members is adjustable along the width direction of the conveying assembly, and each of the drive members is rotatable about an axis perpendicular to the bearing surface of the conveying assembly.

[0010] In one embodiment, a magnetic suction component is also included, which is disposed on the side of the conveying component facing away from the bearing surface and is capable of adsorbing the housing carried on the conveying component.

[0011] In one embodiment, the magnetic attraction assembly includes a plurality of permanent magnets arranged along the preset direction.

[0012] In one embodiment, a first sensor and a second sensor are further included, the first sensor and the second sensor being distributed on at least one side edge in the width direction of the conveying assembly, and the height of the first sensor being smaller than that of the second sensor in the height direction perpendicular to the bearing surface of the conveying assembly.

[0013] In one embodiment, the assembly further includes a baffle and a third sensor disposed at the feed end, the baffle being distributed on both sides of the conveying assembly in the width direction.

[0014] In one embodiment, a cleaning component is also included for cleaning the bearing surface of the conveying component.

[0015] In one embodiment, the cleaning component includes a roller brush arranged in the conveying path of the conveying component and in contact with the bearing surface of the conveying component.

[0016] In one embodiment, a material handling mechanism is also included, which includes a transfer component and a suction cup component. The suction cup component has an adsorption surface for adsorbing the housing, and the transfer component can drive the adsorption component to reciprocate.

[0017] In one embodiment, the suction cup assembly includes an electromagnet and a controller. The electromagnet provides an adsorption force to the adsorption surface, and the controller controls the on / off state of the electromagnet and adjusts the magnitude of the current flowing through the electromagnet.

[0018] A battery production apparatus includes a casing transfer device as described in any of the preferred embodiments above.

[0019] In the aforementioned casing transfer device and battery production equipment, the portion of the shaping channel located at the discharge end can be configured to be approximately the same size as a single casing. Multiple casings, collected in a tray, are first placed on the bearing surface of the conveying assembly and transported from the inlet to the outlet end under the drive of the conveying assembly. As the casings are transported along with the conveying assembly, they pass through the shaping channel and are compressed towards the center of the channel by the action of the baffles. Furthermore, the driving component vibrates the baffles, causing the casings to vibrate and preventing them from jamming within the shaping channel. Therefore, during the passage through the shaping channel, the multiple casings are gradually shaped into a single row under the guidance of the baffles and the vibration, and are ultimately output from the outlet end.

[0033] Please see Figure 1 This utility model provides a housing transfer device 100, which can shape multiple rows of housings 20 into a single row during the conveying process and output them one by one to the next process. The housings 20 can be square, cylindrical, or other non-standard shapes. Specifically, in this embodiment, the housings 20 are cylindrical, suitable for cylindrical batteries.

[0034] In addition, this utility model also provides a battery production equipment, which includes the aforementioned casing transfer device 100. The casings 20, which are formed into a single row by the casing transfer device 100, can be assembled into batteries after a series of operations such as testing and dust removal.

[0035] Please refer to the following: Figure 2 and Figure 3 In one embodiment of the present invention, the housing transfer device 100 includes a conveying component 110 and a shaping component 120.

[0036] The conveying assembly 110 is capable of carrying and conveying the housing 20 in a preset direction, which refers to... Figure 3 The horizontal direction is shown. The cylindrical housing 20 is placed vertically on the bearing surface of the conveying assembly 110 with its opening facing upwards. The conveying assembly 110 has an inlet end and an outlet end, which are spaced apart along a preset direction. The incoming housing 20 is first placed at the inlet end and then conveyed by the conveying assembly 110 to the outlet end.

[0037] Specifically, the conveying assembly 110 includes a belt, rollers, and a power element. The rollers include at least two sets, respectively installed at both ends of the bracket 130 of the housing transfer device 100 along a predetermined direction; the belt is fitted over the rollers at both ends of the bracket 130 to support the housing 20; the power element, such as a motor, drives the belt to circulate around the rollers, thereby conveying the housing 20. The surface of the belt is flat, and the housing 20 is not easily tipped over when placed on the belt surface. Of course, in other embodiments, the conveying assembly 110 may also take other forms, such as a conveyor chain or a conveyor plate.

[0038] The shaping assembly 120 includes a retaining edge 121 and a driving member 122. The retaining edge 121 surrounds a shaping channel 101 extending along a predetermined direction. The retaining edges 121 are distributed on both sides of the conveying assembly 110 in the width direction, and each side may have a single long retaining plate 121 or multiple short retaining edges 121 connected end-to-end. The retaining edges 121 are located above the bearing surface of the conveying assembly 110, allowing the housing 20 conveyed by the conveying assembly 110 to pass through the shaping channel 101. Furthermore, the shaping channel 101 narrows from the inlet end to the outlet end. That is, the closer to the outlet end, the smaller the width of the shaping channel 101. Therefore, as multiple housings 20 are conveyed by the conveying assembly 110 towards the outlet end, they can be squeezed towards the center of the shaping channel 101 under the action of the retaining edges 121 on both sides.

[0039] The portion of the shaping channel 101 near the discharge end can be configured to be approximately the same size as a single housing 20. That is, the width of the portion of the shaping channel 101 at the discharge end is approximately the same as the diameter of a single housing 20, generally slightly larger than the diameter of a single housing 20 but smaller than the diameter of two housings 20. Therefore, the shaping channel 101 only allows housings 20 to pass through in a single row.

[0040] The drive component 122 can be a structure that combines a cylinder, an electric cylinder, or a motor with a cam, capable of driving the retaining edge 121 to vibrate. During the process of the conveying assembly 110 driving the housing 20 along the forming channel 101, the drive component 122 drives the retaining edge 122 to vibrate, thereby causing the housing 20 to vibrate as well. This prevents the housing 20 from jamming when pressed into the center of the forming channel 101. Ultimately, multiple housings 20 are gradually shaped into a single row under the guidance and vibration of the retaining edge 121, and are finally output one by one from the discharge end of the conveying assembly 110.

[0041] In this embodiment, each retaining edge 121 is rotatable about an axis perpendicular to the bearing surface of the conveying assembly 110. Specifically, the retaining edge 121 can be mounted on the bracket 130 via a support plate 131, and the retaining edge 121 and the support plate 131 are connected by a rotating shaft. The driving member 122 can drive the retaining edge 121 to reciprocate around the axis to achieve vibration, so the vibration amplitude of the retaining edge 121 is larger and the vibration effect is more obvious.

[0042] It should be noted that in other embodiments, the baffle 121 may also be fixed to the bracket 130, and the drive member 122 may achieve vibration by driving the baffle 121 to deform.

[0043] In this embodiment, the position of each drive member 122 is adjustable along the width direction of the conveying assembly 110, and each drive member 122 is capable of rotating about an axis perpendicular to the bearing surface of the conveying assembly 110.

[0044] The width direction is perpendicular to the preset direction, that is... Figure 3 As shown in the vertical direction. By adjusting the position of the drive member 122 along the width direction, the distance between the drive member 122 and the stop edge 121 can be adjusted. By rotating the drive member 122, the angle between the drive end of the drive member 122 and the stop edge 121 can be adjusted. In this way, it is convenient for the drive member 122 and the stop edge 121 to be smoothly connected.

[0045] Specifically, the drive component 122 can be mounted on the bracket 130 via the connecting plate 132. The drive component 122 and the connecting plate 132 are connected by a rotating shaft, allowing the drive component 122 to rotate. Furthermore, the connecting plate 132 has a slotted hole (not shown in the figure), and the connecting plate 132 is mounted on the bracket 130 through the slotted hole and a threaded fastener, so that the connecting plate 132 can drive the drive component 122 to move along the width direction of the conveying assembly 110.

[0046] Furthermore, in this embodiment, a gap is formed between the bottom edge of the retaining edge 121 and the bearing surface of the conveying assembly 110 (not shown).

[0047] Specifically, the height of this gap is generally slightly larger than the diameter of a single housing 20. On the one hand, since the retaining edge 121 does not contact the bearing surface of the conveying assembly 110, it does not affect the normal conveying of the conveying assembly 110. On the other hand, when the housing 20 tilts, the housing 20 can be squeezed out of the shaping channel 101 through the gap between the retaining edge 121 and the bearing surface of the conveying assembly 110, thereby preventing the tilted housing 20 from blocking the shaping channel 101 and ensuring the continuous transfer of the housing 20.

[0048] Please refer to the following: Figure 4 In this embodiment, the housing transfer device 100 further includes a magnetic suction component 140, which is disposed on the side of the conveying component 110 facing away from the bearing surface and is capable of adsorbing the housing carried on the conveying component 110.

[0049] Specifically, the bracket 130 is provided with a mounting plate 133 extending in a preset direction, and the magnetic suction component 140 is disposed on the mounting plate 133. The magnetic suction component 140 can provide an attractive force for the housing 20 conveyed by the conveying component 110, effectively preventing the housing 20 from tipping over during transportation. Moreover, the magnetic suction component 140 can position the housing 20 through its attractive action, thus eliminating the need for a cup holder in traditional equipment, thereby simplifying the structure of the housing transfer device 100 and reducing costs.

[0050] Furthermore, in this embodiment, the magnetic attraction component 140 includes a plurality of permanent magnets 141 arranged along a preset direction. The permanent magnets 141 are magnetic without being energized, thus eliminating the need for additional wiring harnesses and further simplifying the structure of the housing transfer device 100. Moreover, the positions of the plurality of permanent magnets 141 are adjustable, thereby allowing for adjustment of the magnitude of the adsorption force on the bearing surface of the conveying component 110 as needed.

[0051] Please refer to it again. Figure 2 In this embodiment, the housing transfer device 100 further includes a first sensor 150 and a second sensor 160. The first sensor 150 and the second sensor 160 are distributed on at least one side edge in the width direction of the conveying assembly 110, and in the height direction perpendicular to the bearing surface of the conveying assembly 110, the height of the first sensor 150 is smaller than that of the second sensor 160.

[0052] Both the first sensor 150 and the second sensor 160 can be electrical sensors. The first sensor 150 is used to detect the bottom of the housing 20 to monitor the conveying progress of the housing 20 in real time; while the second sensor 160 is used to detect the top of the housing 20 to determine whether the housing 20 has tipped over.

[0053] Furthermore, in this embodiment, the housing transfer device 100 also includes a baffle 170 and a third sensor 180 disposed at the feed end. The baffle 170 is distributed on both sides of the conveying assembly 110 in the width direction. The baffle 170 can prevent the housing 20 fed to the feed end from slipping off the bearing surface of the conveying assembly 110, while the third sensor 180 can detect whether the housing 20 is in place.

[0054] Please refer to the following: Figure 5 In this embodiment, the housing transfer device 100 further includes a cleaning component 190, which is used to clean the bearing surface of the conveying component 110. The cleaning component 190 can keep the bearing surface of the conveying component 110 clean, thereby preventing the housing 20 from being secondary contaminated during the conveying process.

[0055] Furthermore, in this embodiment, the cleaning component 190 includes a roller brush 191, which is arranged in the conveying path of the conveying component 110 and contacts the bearing surface of the conveying component 110. The axis of rotation of the roller brush 191 is approximately parallel to the bearing surface of the conveying component 110 and approximately perpendicular to a preset direction. As the conveying component 110 continues to operate, it will drive the roller brush 191 to rotate continuously, thereby achieving automatic cleaning of the bearing surface.

[0056] It should be noted that in other embodiments, the cleaning component 190 may also clean the bearing surface of the conveying component 110 by other means, such as blowing air.

[0057] Please refer to it again. Figure 1 In this embodiment, the housing transfer device 100 further includes a material picking mechanism 200. The material picking mechanism 200 is used to pick up the housing 20 from the tray (not shown) and load the picked-up housing 20 into the housing transfer device 100.

[0058] The material handling mechanism 200 can grasp the shells 20 in the tray using methods such as negative pressure adsorption, mechanical clamping, and magnetic adsorption. Optionally, the material handling mechanism 200 can grasp the entire tray, that is, grasp all the shells 20 in the tray at once. Therefore, the number of times the material handling mechanism 200 reciprocates between the tray and the shell transfer device 100 can be significantly reduced throughout the entire production process.

[0059] For more details, please refer to the following: Figure 6 The material handling device 200 includes a transfer component 210 and an adsorption component 220. The adsorption component 220 has an adsorption surface for adsorbing the housing 20. The transfer component 210 can drive the adsorption component 220 to move back and forth.

[0060] The transfer assembly 210 drives the adsorption assembly 220 to reciprocate between the tray (picking position) and the feeding end (loading position) of the housing transfer device 100, thereby achieving the gripping and loading of the housing 20. Specifically, the transfer assembly 210 includes three line drive modules, which can drive in three mutually perpendicular directions, thereby driving the adsorption assembly 220 to move in three degrees of freedom. Each line drive module can adopt the same structure and can be driven by an electric cylinder or a pneumatic cylinder. Of course, the transfer assembly 210 can also be a multi-axis robot.

[0061] The adsorption surface of the adsorption component 220 increases its contact area with the housing 20, thereby facilitating the gripping of the entire housing 20. The adsorption surface of the adsorption component 220 can adsorb the housing 20 through negative pressure or magnetic attraction, thus achieving the gripping of the housing 20. In this way, the material handling mechanism 200 will not squeeze the housing 20 during the gripping process, thus minimizing the risk of damage to the housing 20.

[0062] Furthermore, in this embodiment, the adsorption component 220 includes an electromagnet 221 and a controller (not shown). The electromagnet 221 can provide adsorption force to the adsorption surface, and the controller can control the on / off state of the electromagnet 221 and adjust the magnitude of the current flowing through the electromagnet 221.

[0063] When current flows through electromagnet 221, it generates a magnetic force that attracts the housing 20. Disconnecting the current causes the magnetic force of electromagnet 221 to dissipate, releasing the attracted housing 20. In other words, the controller can grasp and release the housing 20 by controlling the on / off state of electromagnet 221, thereby reducing the complexity of the material handling device 200 structure. Furthermore, the controller can adjust the magnitude of the attraction force by regulating the current flowing through electromagnet 221, thus expanding its applicability.

[0064] Of course, in other embodiments, adsorption holes communicating with a negative pressure device (not shown) can be opened on the adsorption surface, and the housing 20 can be adsorbed by negative pressure. The gripping and releasing of the housing 20 can be achieved by controlling the on and off of the negative pressure device, and the magnitude of the adsorption force can be adjusted by adjusting the magnitude of the negative pressure of the negative pressure device.

[0065] In the aforementioned housing transfer device 100 and battery production equipment, the portion of the shaping channel 101 located at the discharge end can be configured to be approximately the same size as a single housing 20. Multiple housings 20, collected from a tray, are first placed on the bearing surface of the conveying assembly 110 and conveyed from the inlet to the outlet under the drive of the conveying assembly 110. During the conveying process with the conveying assembly 110, the multiple housings 20 pass through the shaping channel 101 and are pressed towards the center of the shaping channel 101 by the action of the retaining edge 121. Furthermore, the driving member 122, by driving the retaining edge 121 to vibrate, causes the housings 20 to vibrate, thereby preventing the housings 20 from getting stuck in the shaping channel 101. Therefore, during the process of passing through the shaping channel 101, the multiple housings 20 will be gradually shaped into a single row under the guidance and vibration of the retaining edge 121 and finally output from the outlet end.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
