Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a vibratory feeding mechanism for conveying battery caps. Background Technology

[0002] After the lithium battery cap is manufactured, due to process limitations, it is transferred from the processing station to the assembly station. During this process, the quality of the battery cap needs to be monitored.

[0003] For example, in the Chinese invention patent with announcement number CN112660801 B, entitled "A Battery Cover Conveying Line", it is specifically disclosed that the conveying line includes a conveying line bracket, a cover carrier assembly, and a cover carrier positioning assembly. The conveying line bracket is provided with a first guide rail. The cover carrier assembly includes a tray assembly and a gripper assembly placed on the tray assembly. The tray assembly is slidably placed on the first guide rail. One end of the gripper assembly forms a positioning drive groove, and the other end forms a gripper portion. The gripper portion is configured to grip the battery cover. The cover carrier positioning assembly includes a positioning member, which is configured to be able to be inserted into the positioning drive groove to position the gripper assembly, and at the same time drive the gripper portion to open to release the gripping of the battery cover.

[0004] The battery cover conveyor line described above has high transmission accuracy during operation and high accuracy in placing the battery cover, thereby avoiding the occurrence of battery cover warping.

[0005] For example, Chinese invention patent CN111540940A, entitled "A Battery Covering Machine," discloses a system comprising: a conveyor belt for conveying semi-finished batteries; and, sequentially distributed along the conveyor belt's conveying direction, a battery feeding mechanism for transferring semi-finished batteries onto the conveyor belt; a tab adjusting mechanism for adjusting the tab direction of the semi-finished batteries; a tab bending mechanism for bending vertical tabs; a cover welding mechanism; a quality inspection mechanism for detecting the quality after welding; a defect removal mechanism for eliminating substandard semi-finished batteries; and a transfer mechanism for transferring welded and qualified batteries to the next process on a conveyor line.

[0006] The above solution, through the close connection and cooperation of the above mechanisms, effectively and reliably completed the welding of the battery and the battery cover, and also realized the fully automated welding operation, which greatly improved the battery production efficiency.

[0007] However, in actual processing, the above solutions involve transporting multiple battery covers via a conveyor belt after processing. Multiple workers are then assigned to the side of the conveyor belt to visually inspect the quality of the battery covers. This quality monitoring and transmission method significantly reduces processing efficiency and also requires additional labor costs.

[0008] To address these issues, a vibratory feeding mechanism for conveying battery caps is proposed. Utility Model Content

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.

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Example 1:

[0040] See attached document Figure 1-6 This embodiment 1 proposes a vibratory feeding mechanism for conveying battery caps.

[0041] It includes three parts: body 1, feeding unit 2 and feeding unit 3. The feeding unit 2 includes a vibratory plate 21 installed on the body 1. A vibratory plate storage bin 22 is also installed on one side of the vibratory plate 21, which can intermittently transport battery covers into the vibratory plate 21.

[0042] It should be noted that the vibratory feeder 21 in this embodiment is covered with a thin adhesive layer, which can increase the friction between the lightweight battery cover and the vibratory feeder 21, and prevent the battery cover from moving too far during displacement, thus avoiding congestion of the conveying channel and improving the conveying stability to a certain extent.

[0043] The battery cover in this embodiment includes two parts, which are cylindrical structures with different diameters. The smaller diameter cylinder (electrode part) is coaxially located at the upper middle part of the larger diameter cylinder (battery cover carrier part).

[0044] Multiple battery covers are distributed and conveyed in the vibratory feeder 21. During conveying, the battery covers are conveyed one by one along the conveying direction with the electrode part facing upward, and the spacing between them is close to equal.

[0045] Example 2:

[0046] This embodiment 2 is based on embodiment 1, and further describes and explains the feeding unit 3.

[0047] See attached document Figure 2 The feeding unit 3 includes a feeding track 31 connected to the discharge port side of the vibratory feeder 21 and used for conveying the battery cover. It is worth noting that the feeding track 31 in this embodiment also uses a vibration stepping method to convey the battery cover. The feeding track 31 is a vibratory track and extends in a straight line along one side. A vibration motor is provided below the feeding track 31. The linear track for vibration conveying is a known technology. The specific setting of the vibration motor will not be described in detail here.

[0048] In addition, due to the use of vibration conveying and the lightweight nature of the battery cover itself, a groove 311 is provided on the upper surface of the feeding track 31 in this embodiment. The starting end of the groove 311 is connected to the discharge port of the vibratory plate 21, and the cross-section of the groove 311 is an inverted convex shape and is used to convey the battery cover vibrated out of the vibratory plate 21.

[0049] The battery cover vibrating out of the vibratory plate 21 will "rest" on the two steps above the groove 311, and will move forward by the vibration of the feed track 31.

[0050] Example 3:

[0051] This embodiment 3 is based on embodiment 2, and further describes and explains the feeding track 31.

[0052] See attached document Figure 2-3 The upper end of the feeding track 31 and one or both sides of the through groove 312 are provided with pressure strips 313. The number of pressure strips 313 is not limited. A whole strip can be used to cover the top of the through groove 312, or several strips can be set up and distributed according to actual needs.

[0053] In this embodiment, the pressure strip 313 is positioned parallel above the battery cover and is in contact with the outer end face of the electrode portion in the middle of the upper end of the battery cover, which can effectively limit the lateral displacement of the battery cover.

[0054] Alternatively, pressure strips 313 can be provided on the upper ends of both sides of the groove 311.

[0055] It is worth noting that the pressure strip 313 can also prevent the battery cover from vibrating off the vibrating plate 21. Since the pressure strip 313 is parallel to the groove 311 and the lower end surface of the pressure strip 313 is higher than the upper end surface of the battery cover, it can limit the up and down movement of the battery cover and prevent the battery cover from vibrating off.

[0056] When a pressure strip 313 is used on one side, a pusher 314 parallel to the pressure strip 313 is also provided at the upper end of the feeding track 31. The side end face of the battery cover is located on the moving path of the pusher 314. The pusher 314 is located on the other side of the through groove 312 and can reciprocate towards the pressure strip 313. A drive structure such as an electric push rod or motor is provided on one side of the pusher 314, which can uniformly push the battery cover towards the pressure strip 313, thereby ensuring that the battery cover is on the same horizontal line.

[0057] Optionally, the distance between the pressure strip 313 and the groove 311 is adjustable.

[0058] To improve the effect of pushing the battery cover, the pusher 314 has several arc-shaped grooves 3141 spaced apart on one side of the end face facing the battery cover, and the arc-shaped grooves 3141 are adapted to the outer end face of the battery cover.

[0059] Example 4:

[0060] This embodiment 4 is based on embodiment 3, and further describes and explains the visual monitoring module 4.

[0061] See attached document Figure 1-3It is worth mentioning that a visual monitoring module 4 and a transfer suction cup 10 are also provided on one side of the feeding track 31. The transfer suction cup 10 is movably installed on the machine body 1 and its movement path is perpendicular to the feeding track 31. The transfer suction cup 10 can achieve displacement in both horizontal and vertical directions, that is, it can move upward towards the feeding track 31 to uniformly adsorb the battery cover located on the feeding track 31 under negative pressure and transfer the battery cover by moving laterally. Multiple transfer suction cups 10 are provided and can perform displacement and adsorption operations simultaneously.

[0062] In this case, the length of the pusher plate 314 is greater than the length of the multiple material transfer suction cups 10 arranged in rows.

[0063] The visual acquisition direction of the visual monitoring module 4 is perpendicular to the feeding track 31 and it is located between the vibrating plate 21 and the transfer suction cup 10. It can monitor the appearance defects of the battery cover conveyed on the vibrating plate 21. When appearance defects such as incorrect size or insufficient smoothness occur, the visual monitoring module 4 can quickly identify them and perform corresponding operations.

[0064] The visual monitoring module 4 includes an upper lens 41 vertically positioned above the feed track 31. The visual acquisition direction of the upper lens 41 is perpendicular to the center line of the groove 311, enabling visual acquisition from above the battery cover. The specific defect assessment method and logic are well-known technologies and will not be elaborated upon here.

[0065] A through slot 312 is provided in the groove 311 and directly below the upper lens 41. The through slot 312 passes through the lower end face of the feeding track 31. The visual monitoring module 4 also includes a lower lens 42 that is vertically arranged directly below the through slot 312. The visual acquisition direction of the lower lens 42 is directly below the through slot 312, and it can perform visual image acquisition and monitoring of the bottom of the battery cover located on the feeding track 31 through the through slot 312.

[0066] This embodiment also includes an NG material ejector 5 located on the side of the visual monitoring module 4 away from the vibratory feeder 21. The NG material ejector 5 includes an ejection channel 51 and an NG material collection box 52 connected inside the feed track 31.

[0067] It should be noted that the material return channel 51 in this case uses an adsorption method for material return operation. That is, negative pressure can be generated inside the material return channel 51. When the visual monitoring module 4 detects a defective product, when the defective product moves to the area below the collection port of the material return channel 51, the material return channel 51 generates negative pressure to suck the defective product into the NG material collection box 52 for storage.

[0068] The negative pressure in the unloading channel 51 can be generated using known equipment such as a vacuum pump. The specific principle is common knowledge and will not be elaborated on here.

[0069] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
