Description

Technical Field

[0001] The present invention relates to the technical field of automated equipment, and particularly relates to a vibrating feeding device and method for a lithium battery sealing body. Background Art

[0002] After the sealing body of a lithium battery, i.e., the battery cover, is processed, due to process limitations, the battery cover will be transferred from the processing station to the assembly station. During this process, the quality of the battery cover needs to be monitored.

[0003] In the prior art, a Chinese invention patent with a publication number of CN112660801A and a patent name of "A Battery Cover Plate Conveyor Line" discloses a technical solution including a conveyor line bracket, a cover plate carrier assembly, and a cover plate carrier positioning assembly. A first guide rail is provided on the conveyor line bracket. The cover plate carrier assembly includes a tray assembly and a jaw assembly placed on the tray assembly. The tray assembly is slidably placed on the first guide rail. One end of the jaw assembly forms a positioning drive groove, and the other end forms a jaw portion. The jaw portion is configured to clamp the battery cover plate. The cover plate carrier positioning assembly includes a positioning member configured to be able to insert into the positioning drive groove to position the jaw assembly and simultaneously drive the jaw portion to open to release the clamping of the battery cover plate.

[0004] The above-mentioned battery cover plate conveyor line has high transmission accuracy during operation and high accuracy in the placement position of the battery cover plate, thereby avoiding the occurrence of warping of the battery cover plate.

[0005] Another example is a Chinese invention patent with a publication number of CN111540940A and a patent name of "A Battery Capping Machine", which discloses a conveyor belt for conveying semi-finished batteries; and distributed in sequence along the conveying direction of the conveyor belt: a battery feeding mechanism for transferring the semi-finished battery onto the conveyor belt; an ear adjusting mechanism for adjusting the direction of the tabs of the semi-finished battery; an ear bending mechanism for bending the vertical tabs; a capping mechanism, a quality inspection mechanism for detecting the quality after welding, a defective product discharging mechanism for discharging unqualified semi-finished batteries after welding, and a transfer line mechanism for transferring the batteries that have been welded and are qualified in quality to the next process line.

[0006] Through the close connection and cooperation of the above-mentioned mechanisms, the above-mentioned solution effectively and reliably completes the welding of the battery and the battery cover, and at the same time realizes the fully automated operation of welding, greatly improving the production efficiency of the battery.

[0007] However, in the actual processing process, the battery cover needs to be transferred to the assembly station after the processing is completed. The above solution is to transport the battery cover by means of a transmission belt after processing. During the transfer, the battery cover is clamped one by one by the clamping claws to transfer the station. This transfer method is not only inefficient, but also the clamping force of the clamping claws is too large to easily cause damage to the battery cover. Therefore, how to transfer the battery cover quickly and efficiently without causing damage to the battery cover is a problem that needs to be solved urgently.

[0008] To this end, a vibration feeding device and method for a lithium battery sealing body are proposed to solve the above-mentioned problems. Summary of the invention

[0009] Technical issues solved

[0012] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0013] The present invention provides a vibrating feeding device for a lithium battery sealing body, comprising a machine body, a feeding unit, a feeding unit and a discharging track, wherein the feeding unit comprises a vibrating plate arranged on the machine body, wherein battery covers are distributed in the vibrating plate; the feeding unit comprises a feeding track connected to one side of a discharging port of the vibrating plate and used for conveying the battery covers; the discharging track is used for conveying a tray for placing the battery covers, and a material transfer suction cup for transferring the battery covers is arranged between the feeding track and the discharging track; wherein the feeding track and the discharging track are perpendicular to each other, and a transfer track is also arranged between the feeding track and the discharging track, and the transfer track comprises a first push piece and a second push piece which are symmetrically distributed and located below the material transfer suction cup, and the two push pieces can move toward each other and abut against the battery cover located therebetween.

[0014] Furthermore, the feed track and the transfer track are both vibrating tracks and extend linearly toward one side of the discharge track.

[0015] Furthermore, grooves are provided on the upper end surfaces of the feed track and the transfer track, the cross-section of the grooves is in the shape of an inverted convex letter and are used to transport the battery covers vibrated out from the vibration plate.

[0016] Furthermore, it also includes a visual monitoring module, which includes an upper lens and a lower lens vertically arranged above and below the feed track, a through slot is opened in the groove and directly below the upper lens, and the visual acquisition direction of the lower lens is directly below the through slot.

[0017] Further, a pressing strip is provided at the upper end of the feeding track and on one side of the through groove. The pressing strip is parallel to and above the battery cover and is in contact with the electrode part in the middle of the upper end of the battery cover.

[0018] Further, a plurality of arc-shaped grooves are arranged at intervals on the end face of the first pushing piece facing the battery cover. The arc-shaped grooves are adapted to the outer end face of the battery cover. The second pushing piece is connected to one side of the pressing strip and is in contact with the electrode part in the middle of the upper end of the battery cover.

[0019] Further, a third pushing piece is further included. The third pushing piece is elastically and movably installed on the transfer track, and is parallel to and directly below the second pushing piece and is tangent to the lower edge of the battery cover.

[0020] Further, a plurality of arc-shaped notch grooves are arranged at intervals on the end face of the third pushing piece facing the battery cover.

[0021] Further, the third pushing piece and the second pushing piece move away from each other through a gear set. When the first pushing piece moves towards the second pushing piece, the third pushing piece contacts the outer edge of the battery cover before the second pushing piece and stores a certain amount of elastic potential energy.

[0022] A vibration feeding method for a lithium battery sealing body is applied to a vibration feeding device for a lithium battery sealing body as described above, and includes the following steps:

[0023] Step 1: The battery cover is sent out onto the feeding track through a vibrating disc, and at the same time, the feeding track and the transfer track are used to convey the battery cover towards the discharge track one by one.

[0024] Step 2: The poses of the battery covers located between the two pushing pieces are adjusted by the opposite movement of the two pushing pieces to ensure that the axes of a plurality of battery covers are in the same plane.

[0025] Step 3: The transfer suction cup moves downwards to adsorb a plurality of battery covers with adjusted poses and send them to the tray on the discharge track.

[0026] Beneficial effects

[0027] The technical solution provided by the present invention has the following beneficial effects compared with the known public technology:

[0028] The present invention realizes the cyclic conveyance of the battery cover by setting up a feeding unit and a feeding unit, and a transfer track is also arranged between the feeding track and the discharge track.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0048] The present invention will be further described below in conjunction with embodiments.

[0049] Embodiment 1:

[0050] Refer to the appendix Figure 1-2 , this Embodiment 1 proposes a vibrating feeding device for a lithium battery sealing body.

[0051] It includes three parts: a machine body 1, a feeding unit 2, and a feeding unit 3. The feeding unit 2 includes a vibrating disk 21 provided on the machine body 1. On one side of the vibrating disk 21, there is also provided a vibrating disk storage bin 22, which can intermittently convey the battery covers into the vibrating disk 21.

[0052] It should be noted that the inside of the vibrating disk 21 in this embodiment is coated with a thin glue layer, which can increase the friction between the relatively light battery covers and the vibrating disk 21, avoid the battery covers moving too long a distance during displacement and causing congestion in the conveying channel, and improve the conveying stability to a certain extent.

[0053] The battery covers in this embodiment include two parts, and the overall shape is two cylindrical structures with different diameters up and down. Among them, the cylinder with a smaller diameter (electrode part) is coaxially located in the middle of the upper end of the cylinder with a larger diameter (battery cover carrier part). It should be noted that the inside of the battery cover carrier is hollow, and a ring-shaped shell made of a harder material than the battery cover carrier is coaxially provided at its lower end.

[0054] A plurality of battery covers are distributed and conveyed in the vibrating disk 21. During conveyance, the battery covers are conveyed one by one along the conveying direction with the electrode part facing upward, and the spacing is approximately equal.

[0055] Refer to the appendix Figure 2 , the feeding unit 3 includes a feeding track 31 connected to one side of the discharge port of the vibrating disk 21 and used for conveying the battery covers. It should be noted that the feeding track 31 in this embodiment also conveys the battery covers in a vibrating stepping manner. The feeding track 31 is a vibrating track and extends linearly along one side direction. A vibrating motor is provided below the feeding track 31. The linear vibrating conveying track is a well-known technology, and the specific setting method of the vibrating motor will not be elaborated here too much.

[0056] In addition, due to the use of the vibrating conveying method and combined with the characteristic that the battery covers themselves are relatively light in mass, in this embodiment, a groove 311 is opened on the upper end surface of the feeding track 31. The starting end of the groove 311 is connected to the discharge port of the vibrating disk 21, and the cross-section of the groove 311 is an inverted convex shape and is used for conveying the battery covers vibrated out from the vibrating disk 21.

[0057] The battery covers vibrated out from the vibrating disk 21 will "rest on" the upper two steps of the groove 311 and achieve stepping through the vibration of the feeding track 31.

[0058] In this embodiment, there is also a discharge track 5. When the battery cover is gradually conveyed to the position to be transferred for the second time, it is necessary to transfer the battery cover onto a dedicated tray 51. There are holes for placing the battery cover on the tray 51, and a transfer suction cup 10 for transferring the battery cover is provided between the feeding track 31 and the discharge track 5.

[0059] It should be noted that there is also a transfer track 6 between the feeding track 31 and the discharge track 5. The upper end surface of the transfer track 6 is also provided with a groove 311 with an inverted convex cross-section. A number of battery covers will wait at the transfer track 6 for the transfer of the transfer suction cup 10.

[0060] It is worth mentioning that in order to avoid the situation that the battery cover is prone to displacement in the groove 311 during the vibration feeding process, this displacement refers to lateral displacement and longitudinal displacement. Therefore, pressure strips 313 are provided on one side or both sides of the upper end of the feeding track 31 and located beside the through groove 312. The number of pressure strips 313 is not limited. It can directly use a whole strip to cover above the through groove 312, or several strips can be set and arranged according to actual needs.

[0061] In this embodiment, the pressure strip 313 is parallel to the upper side of the battery cover and is in contact with the outer end surface of the electrode part in the middle of the upper end of the battery cover, which can well limit the lateral displacement of the battery cover.

[0062] Pressure strips 313 can also be provided at both upper ends of the two sides of the groove 311.

[0063] It should be noted that the pressure strip 313 can also prevent the battery cover from vibrating out of the vibrating disk 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 part, it can limit the up and down movement of the battery cover and prevent the battery cover from vibrating out.

[0064] Embodiment 2:

[0065] This Embodiment 2 is based on Embodiment 1, referring to the appendix Figures 4-6 , and it further describes and explains the transfer track 6 between the feeding track 31 and the discharge track 5.

[0066] The feed track 31 is perpendicular to the discharge track 5, and the transfer track 6 includes two symmetrically distributed first push pieces 61 and second push pieces 62 located below the material transfer suction cup 10. When the battery cover moves onto the transfer track 6, since the material is conveyed in a vibration manner and in order to ensure smooth conveying, the distance between the two side end faces of the groove 311 will be greater than the diameter of the battery cover. Therefore, during vibration conveying, the axes of several battery covers are not in the same horizontal plane. Therefore, when the material transfer suction cup 10 is adsorbed, it is easy to cause multiple suction cup mouths to be not concentric and coaxial with the battery cover. Once the offset is too large, the battery cover will fall off. Therefore, the battery cover needs to be aligned before the material transfer suction cup 10 is adsorbed to facilitate the adsorption of the material transfer suction cup 10. In this embodiment, the two push pieces can move toward each other and contact the battery cover located between the two, so that several battery covers are aligned.

[0067] In order to improve the effect of pushing the battery cover, a plurality of arc grooves 611 are arranged at intervals on the end surface of the first push piece 61 facing the battery cover, and the arc grooves 611 are matched with the outer end surface of the battery cover.

[0068] Similar to the function of the pressure strip 313 , the second push piece 62 can prevent the pressure strip 313 from being displaced when vibrating forward. The second push piece 62 is also in contact with the electrode portion in the middle of the upper end of the battery cover and connected to one side of the pressure strip 313 .

[0069] In this embodiment, the first push piece 61 and the second push piece 62 are driven by telescopic motors arranged on both sides of the feeding track 31 respectively.

[0070] Embodiment 3:

[0071] Reference Figures 10-11 This embodiment is based on embodiment 2. The device in this embodiment further includes a third push piece 63. The third push piece 63 is elastically and movably mounted on the transfer track 6. When the first push piece 61 pushes the battery cover to move in the groove 311, in order to avoid the hollow battery cover from contacting the other side and causing a concave deformation, the elasticity of the third push piece 63 can ensure that the position remains consistent while providing a certain buffer to avoid damage to the battery cover caused by hard squeezing. In this embodiment, the third push piece 63 is located parallel to and directly below the second push piece 62 and is tangent to the lower edge of the battery cover.

[0072] Optionally, the third push piece 63 can also be set on the symmetrical plane of the first push piece 61, that is, on the same plane as the position where the first push piece 61 contacts. Its purpose is to contact the relatively hard outer end surface of the battery cover without directly contacting the hollow part, avoiding the possibility of slight concave deformation.

[0073] In the drawings, only the case where the third pushing piece 63 is arranged below the second pushing piece 62 is shown. In addition, also to improve the effect of pushing the battery cover, a plurality of arc-shaped notch grooves 631 are arranged at intervals on one end face of the third pushing piece 63 facing the battery cover, and the arc-shaped notch grooves 631 are adapted to the outer end face of the battery cover.

[0074] Embodiment 4:

[0075] Refer to the attached Figure 11 , this Embodiment 4 is based on Embodiment 3, and further describes and explains the action steps of the third pushing piece 63.

[0076] In this embodiment, when it is necessary to suck away the battery cover by the material transfer suction cup 10, it is necessary to release the restraint of the second pushing piece 62 on the upper end face of the battery cover. Due to the vibration of the vibrating disk 21 and the vibrating track, there is still a vibration feeling at the groove 311. And in order to avoid damaging the battery cover, the pushing force and amplitude of the first pushing piece 61 are not very large, and there is still a gap between the battery cover and the side wall of the groove 311. In order to weaken the influence of this gap on the material transfer suction cup 10, in this embodiment, when the second pushing piece 62 is withdrawn, the third pushing piece 63 will generate a thrust toward the first pushing piece 61 side, that is, a surrounding space is jointly formed by the third pushing piece 63 and the first pushing piece 61 to limit the displacement of the battery cover.

[0077] Specifically, the third pushing piece 63 and the second pushing piece 62 are movably separated through a gear set 64, and when the first pushing piece 61 moves toward the second pushing piece 62 side, the third pushing piece 63 contacts the outer edge of the battery cover prior to the second pushing piece 62 and accumulates a certain amount of elastic potential energy.

[0078] The gear set 64 includes a rotating shaft rotatably installed in the transfer track 6, a gear is sleeved on the outer side of the rotating shaft, and tooth rails meshing with the gear are respectively arranged at the lower end of the second pushing piece 62 and the upper end of the third pushing piece 63. Therefore, when the second pushing piece 62 moves toward the side away from the first pushing piece 61, the bottom of the second pushing piece 62 will make the gear rotate, and then through the cooperation of the gear and the third pushing piece 63, the third pushing piece 63 moves toward the side close to the first pushing piece 61, which can ensure that the top of the battery cover is not limited by the second pushing piece 62, and at the same time can jointly form a surrounding space with the first pushing piece 61 to limit the displacement of the battery cover.

[0079] It is worth mentioning that a visual monitoring module 4 and a material transfer suction cup 10 are also provided on one side of the feeding track 31. The material transfer suction cup 10 is movably installed on the machine body 1, and its moving path is perpendicular to the feeding track 31. The material transfer suction cup 10 can achieve displacements in both horizontal and vertical directions, that is, it can move upward above the feeding track 31 to uniformly adsorb the battery covers located on the feeding track 31 under negative pressure and transfer the battery covers through horizontal movement. Multiple material transfer suction cups 10 are provided and can perform displacement and adsorption operations simultaneously.

[0080] In this case, the length of the pushing piece 314 is greater than the length of the arrangement of the multiple material transfer suction cups 10.

[0081] The visual acquisition direction of the visual monitoring module 4 is perpendicular to the feeding track 31, and it is located between the vibrating disk 21 and the material transfer suction cup 10. It can monitor the appearance defects of the battery covers conveyed on the vibrating disk 21. When appearance defects such as incorrect dimensions or insufficient smoothness occur, they can be quickly identified by the visual monitoring module 4 and corresponding operations can be carried out.

[0082] The visual monitoring module 4 includes an upper lens 41 vertically arranged above the feeding track 31. The visual acquisition direction of the upper lens 41 is perpendicular to the midline of the groove 311, and it can perform visual acquisition from above the battery cover. The specific defect evaluation methods and logics are well-known technologies and will not be elaborated here.

[0083] A through groove 312 is opened in the groove 311 and directly below the upper lens 41. The through groove 312 penetrates the lower end surface of the feeding track 31. The visual monitoring module 4 further includes a lower lens 42 vertically arranged directly below the through groove 312. The visual acquisition direction of the lower lens 42 is directly opposite to the position directly below the through groove 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 groove 312.

[0084] This embodiment further includes an NG material discharging member 7 provided on the side of the visual monitoring module 4 away from the vibrating disk 21. The NG material discharging member 7 includes a discharging channel 71 communicating with the inside of the feeding track 31 and an NG material collection box 72.

[0085] It should be noted that the discharging operation of the discharging channel 71 in this case is carried out by adsorption, that is, negative pressure can be generated inside the discharging channel 71. When the visual monitoring module 4 detects a defective product, when the defective product moves below the collection port of the discharging channel 71, the discharging channel 71 generates negative pressure to suck the defective product into the NG material collection box 72 through the discharging channel 71 for storage.

[0086] The generation of negative pressure in the discharging channel 71 can use well-known equipment such as a vacuum pump. Its specific principle is common knowledge and will not be elaborated here.

[0087] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the present invention.
