Description

Technical Field

[0001] The present invention relates to the technical field of battery cell detection and sorting, and in particular to a battery cell feeding device and battery pack packaging equipment. Background Art

[0002] With the development of science and technology, the application of batteries has become more and more extensive, especially the application of cylindrical dry batteries in electric vehicles has become more and more popular, and the production of batteries has gradually increased.

[0003] In the process of producing batteries, a battery cell inspection machine is needed to inspect the battery cells during transportation (for example, on a conveyor belt), including inspection of stains, scratches, wrinkles, pinholes, bloating, folded edges, deformation, unqualified inkjet printing, etc. Currently, the battery cell inspection machine is fed with materials (i.e., providing battery cells) manually, which is inefficient and labor-intensive for workers, and cannot meet the growing production needs. Summary of the invention

[0004] In order to solve the problem of low efficiency of the feeding method in the related art, the embodiment of the present invention provides a battery cell feeding device and a battery pack packaging device. The technical solution is as follows:

[0005] In a first aspect, a battery cell loading device is provided, the battery cell loading device comprising a battery cell extraction device, a power transmission device and a first blocking device, wherein:

[0006] The battery cell extraction device extracts a row of battery cells from the battery cell storage device to the first input end of the power transmission device and transmits them;

[0007] The first blocking device is disposed at a first output end of the power transmission device, and the first blocking device regulates the battery cells transported on the power transmission device.

[0008] By using a battery cell extraction device to extract the battery cells in the battery cell storage device to the first input end of the power transmission device, and using a first blocking device to regularize the battery cells transported on the power transmission device, the problem of low efficiency of the loading method in the related art is solved, and the effect of reducing the work intensity of workers and improving the loading efficiency is achieved.

[0009] Optionally, the battery cell feeding device further includes a ramp output device and a second blocking device, wherein:

[0010] The second input end of the ramp output device is opposite to the first output end, and the second output end of the ramp output device is lower than the second input end;

[0011] The second blocking device is located at the second output end, and the second blocking device regulates the battery cells transported on the slope output device.

[0012] Optionally, the first blocking device includes: a first rotating shaft, a first connecting plate, a first shielding plate and two side plates, wherein:

[0013] The first rotating shaft is located above the first output end of the power transmission device, and the lower plane of the first rotating shaft is fixedly connected to the first connecting plate;

[0014] Both sides of one end of the first connecting plate close to the first output end are respectively connected to the side plate bolts, the lower ends of the two side plates are connected to the first shielding plate, and waist-shaped holes for adjusting the inclination angle of the first connecting plate are provided on the two side plates;

[0015] The angle between the first shielding plate and the transmission direction of the power transmission device is less than 90 degrees, and the distance from the first shielding plate to the power transmission device is less than twice the diameter of a battery cell.

[0016] Since the distance from the first shielding plate to the conveyor belt of the power transmission device is less than twice the diameter of a battery cell, stacked battery cells are prevented from being output from the first output end of the power transmission device. In addition, waist-shaped holes for adjusting the inclination angle of the first connecting plate are provided on both side plates, so that technicians can adjust the distance from the lower end of the first shielding plate to the conveyor belt of the power transmission device according to the diameter of the battery cell being transmitted, so that the first blocking device can prevent battery cells of various sizes from being output from the first output end of the power transmission device in a stacked form.

[0017] Optionally, the first blocking device further comprises: a first linkage block, a first spring and a support platform, wherein:

[0018] The upper plane of the first rotating shaft is fixedly connected to the lower plane of the first linkage block, and a mounting hole is provided at one end of the first linkage block close to the first output end, and the mounting hole is interference-fitted with a bolt, and the screw tail of the bolt is fixed to the support platform;

[0019] The first spring extending toward the support platform is disposed at one end of the first linkage block away from the first shielding plate;

[0020] When the first spring is in an initial state, the distance from the lower end of the first shielding plate to the power transmission device is smaller than the diameter of the battery cell, and the first blocking device regulates the battery cells output from the first output end.

[0021] When a battery cell passes independently from under the first baffle plate, the lower end of the first baffle plate cannot be lifted; usually, the battery cell is squeezed by the battery cell behind it on the conveyor belt to pass under the first baffle plate. Since the battery cell is squeezed by the battery cell behind it and blocked by the first baffle plate at the same time, the posture of the battery cell after passing through the first baffle plate is a preset posture, thereby achieving the regularity of the battery cells on the conveyor belt. The cylindrical surface of the battery cell in the preset posture mentioned here is usually parallel to the transmission direction of the power transmission device.

[0022] Optionally, the second blocking device includes: a second rotating shaft, a second linkage block, and a second shielding plate, wherein:

[0023] The second rotating shaft is located above the second output end of the ramp output device, the second shielding plate is located on a side of the second rotating shaft close to the second output end, the distance between the second shielding plate and the ramp output device is smaller than the diameter of the battery cell, and the lower plane of the second rotating shaft is fixedly connected to the upper plane of the second shielding plate;

[0025] Since the distance from the second baffle plate to the slope output device is smaller than the diameter of the battery cell, the battery cell is blocked by the second baffle plate when passing under the second baffle plate, and the battery cell behind the battery cell pushes the battery cell when the slope output device slides down, so that the cylindrical surface of the battery cell is tightly blocked by the second baffle plate with the largest contact area, thereby achieving the regularity of the battery cell and enabling the battery cell to be output from the second output end of the slope output device in a preset posture.

[0026] Optionally, the battery cell extraction device includes a power unit and a pulling unit connected to the power unit, the pulling unit is provided with an extraction head with a battery cell adsorption function, the power unit drives the pulling unit to pull, so that the battery cell in the battery cell storage device is extracted to the first input end of the power transmission device by using the extraction head.

[0027] Since the power part drives the pulling part to pull, the battery cell in the battery cell storage device is pulled to above the first input end of the power transmission device by using the extraction head on the pulling part.

[0028] Optionally, a plurality of magnets or suction cups are provided on the extraction head.

[0029] Optionally, the battery cell extraction device and the battery cell storage device are respectively located on both sides of the power transmission device, and a conveying baffle is provided on one side of the power transmission device close to the battery cell extraction device, and the conveying baffle is provided along the transmission direction of the power transmission device;

[0030] The conveying baffle is provided with an opening matched with the extraction head, the height of the opening is smaller than the diameter of the battery core, and the extraction head can pass through the opening when the pulling part is pulled.

[0031] During the retraction of the pulling part, the extraction head can pass through the opening and be extracted from the power transmission device, and the diameter of the battery cell is higher than the opening and is separated from the extraction head, thereby falling off to the first input end of the power transmission device; the battery cell extraction device extracts the battery cell in the battery cell storage device to the first input end of the power transmission device.

[0032] Optionally, the battery cell feeding device further comprises an adjusting device for adjusting the inclination angle of the ramp output device, the adjusting device comprising a lifting plate and a supporting member, wherein:

[0033] The upper plane of the lifting plate is fixedly connected to the lower plane of the second input end of the ramp output device;

[0034] One end of the lifting plate close to the first output end is rotatably connected to the power transmission device;

[0035] One end of the lifting plate close to the second output end is connected to the supporting member, and the inclination angle of the ramp output device is changed by changing the posture of the supporting member.

[0036] By adjusting the inclination angle of the slope output device, the second output end of the slope output device can be connected to conveyor lines at different horizontal heights, thereby increasing the use range of the battery cell feeding device.

[0037] In a second aspect, a battery pack packaging device is provided, which includes the battery cell loading device involved in the first aspect and any optional implementation manner of the first aspect.

[0038] The battery cell feeding device of the present invention solves the problem of low efficiency of the feeding method in the prior art, thereby achieving the effects of reducing the work intensity of workers and improving the feeding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0050] Figure 1It is a structural schematic diagram of a battery cell loading device provided in one embodiment of the present invention, and the battery cell loading device includes: a battery cell extraction device 10, a power transmission device 20 and a first blocking device 30, wherein: the battery cell extraction device 10 extracts a row of battery cells in the battery cell storage device 40 to the first input end 21 of the power transmission device 20 and transmits them; the first blocking device 30 is arranged at the first output end 22 of the power transmission device 20, and the first blocking device 30 regularizes the battery cells transported on the power transmission device 20. In this way, by using the battery cell extraction device 10 to extract a row of battery cells in the battery cell storage device 40 to the first input end 21 of the power transmission device 20 and transmit them, and using the first blocking device 30 to regularize the battery cells transported on the power transmission device 20, the operation of manual loading is omitted, and the loading efficiency is improved.

[0051] In addition, it should be noted that the embodiment of the present invention uses a cylindrical battery cell for schematic illustration, and the battery cell involved in the present invention may also be a battery cell of other shapes, such as a square battery cell.

[0052] In one possible implementation, Figure 1 As shown, the battery cell extraction device 10 and the battery cell storage device 40 are respectively arranged on both sides of the first input end 21 of the power transmission device 20 .

[0053] In one possible implementation, Figure 2 As shown, the battery cell extraction device 10 includes a power unit 11 and a pulling unit 12 connected to the power unit 11. The pulling unit 12 is provided with a pulling head 13 with a battery cell adsorption function. The power unit 11 drives the pulling unit 12 to pull, so that the pulling head 13 is used to extract the battery cells in the battery cell storage device 40 to the first input end 21 of the power transmission device 20. The pulling unit 12 is driven to pull by the power unit 11; when the pulling unit 12 is extended to make the pulling head 13 close to a row of battery cells in the battery cell storage device 40, the pulling head 13 can adsorb a row of battery cells in the battery cell storage device 40; when the pulling unit 12 is retracted, the pulling head 13 adsorbs the row of battery cells, so that the row of battery cells is moved to the upper side of the first input end 21 of the power transmission device 20, thereby realizing that a row of battery cells in the battery cell storage device 40 is extracted to the upper side of the first input end 21 of the power transmission device 20.

[0054] Among them, a plurality of magnets or suction cups may be provided on the extraction head; the power unit 11 may be a power-driven structure such as a telescopic cylinder, an electric cylinder, a servo module, etc., and this embodiment does not specifically limit the power unit 11.

[0055] Further, such as Figure 1 As shown in the figure, a conveying baffle 50 is provided on one side of the power conveying device 20 close to the battery cell extraction device 10, and the conveying baffle 50 is provided along the conveying direction of the power conveying device 20; Figure 3-1As shown, the conveying baffle 50 is provided with an opening 51 that cooperates with the extraction head 13, and the height of the opening 51 is smaller than the diameter of the battery cell. Figure 3-2 As shown, when the pulling part 12 is pulled, the extraction head 13 can pass through the opening 51. After the row of battery cells is moved to the top of the first input end 21 of the power delivery device 20, the pulling part 12 continues to retract, and since the extraction head 13 can pass through the opening 51 and be pulled out of the power delivery device 20, and since the diameter of the battery cell is higher than the opening 51, it is separated from the extraction head 13, so that the row of battery cells falls off to the first input end 21 of the power delivery device 20. It can be seen from the above content that the battery cell extraction device 10 can extract a row of battery cells in the battery cell storage device 40 to the first input end 21 of the power delivery device 20.

[0056] In one possible implementation, Figure 1 As shown, the power transmission device 20 includes a transmission motor 23 and a horizontal conveyor belt (not shown in the figure). The transmission motor 23 drives the horizontal conveyor belt to work so that the battery cells at the first input end 21 are transported to the first output end 22 of the power transmission device 20.

[0057] The first blocking device 30 is disposed at the first output end 22 of the power delivery device 20, and the first blocking device 30 regulates the cells delivered on the power delivery device 20. In a possible implementation, Figure 4 As shown, the first blocking device 30 includes: a first rotating shaft 31, a first connecting plate 32, a first shielding plate 33 and two side plates 34, wherein:

[0058] like Figure 1 As shown, the first rotating shaft 31 is located above the first output end 22 of the power transmission device 20; Figure 4 As shown, the lower plane of the first rotating shaft 31 is fixedly connected to the first connecting plate 32; the two sides of the end 35 of the first connecting plate 32 close to the first output end 22 are respectively bolted to a side plate 34, the lower ends of the two side plates 34 are connected to the first baffle plate 33, and the two side plates 34 are provided with waist-shaped holes 36 for adjusting the inclination angle of the first connecting plate; the angle between the first baffle plate 33 and the transmission direction of the power transmission device 20 is less than 90 degrees, and the distance from the first baffle plate 33 to the conveyor belt of the power transmission device 20 is less than twice the diameter of a battery cell.

[0059] Since the distance from the first shielding plate 33 to the conveyor belt of the power transmission device 20 is less than twice the diameter of a battery cell, the stacked battery cells are prevented from being output from the first output end 22 of the power transmission device 20. Moreover, waist-shaped holes 36 for adjusting the inclination angle of the first connecting plate are provided on both side plates 34, so that the technicians can adjust the distance from the lower end of the first shielding plate 33 to the conveyor belt of the power transmission device 20 according to the diameter of the battery cell being transmitted, so that the first blocking device 30 can block battery cells of various sizes from being output from the first output end 22 of the power transmission device 20 in a stacked form.

[0060] Further, such as Figure 4 As shown, the first blocking device 30 further includes a first linkage block 35, a first spring 36 and a support platform 37, wherein:

[0061] The upper plane of the first rotating shaft 31 is fixedly connected to the lower plane of the first connecting block 35. The end 38 of the first connecting block 35 close to the first output end is provided with a mounting hole, and the mounting hole is interference fit with a bolt, and the tail of the bolt is on the support platform 37; a first spring 36 extending toward the support platform 37 is provided at the end of the first connecting block 35 away from the first baffle plate 33; when the first spring 36 is in the initial state, the distance from the lower end of the first baffle plate 33 to the conveyor belt of the power transmission device 20 is slightly smaller than the diameter of the battery cell, and the first blocking device 30 regularizes the battery cells output from the first output end 22.

[0062] It should be noted that, in the embodiment of the present invention, the screw tail of the bolt and the first spring 36 are connected to the same support platform. In actual implementation, the screw tail of the bolt and the first spring 36 can be fixed to different support platforms respectively.

[0063] When the first spring 36 is in the initial state, the distance from the lower end of the first baffle plate 33 to the conveyor belt of the power transmission device 20 is slightly smaller than the diameter of the battery cell; when the battery cell passes under the first baffle plate 33, the lower end of the first baffle plate 33 is lifted; at this time, the lower end of the first baffle plate 33 is lifted to drive one end 39 of the first linkage block 35 to move downward, and to drive one end 38 of the first linkage block to be lifted; after the battery cell is detached from the first baffle plate 33, one end 39 of the first linkage block is lifted upward by the return force of the first spring 36, thereby restoring the lower end of the first baffle plate 33 to its original position, and at this time, the distance from the lower end of the first baffle plate 33 to the conveyor belt of the power transmission device 20 is slightly smaller than the diameter of the battery cell.

[0064] In addition, when a battery cell passes independently from under the first shielding plate 33, the lower end of the first shielding plate 33 cannot be lifted; usually, the battery cell is squeezed by the battery cell behind it on the conveyor belt to pass under the first shielding plate 33. Since the battery cell is squeezed by the battery cell behind it and shielded by the first shielding plate 33 at the same time, the posture of the battery cell after passing through the first shielding plate 33 is a preset posture, thereby achieving the regularization of the battery cells on the conveyor belt. The cylindrical surface of the battery cell in the preset posture mentioned here is usually parallel to the transmission direction of the power transmission device 20.

[0065] It should be noted that the first blocking device 30 further includes two support frames disposed on both sides of the power transmission device 20 , and the two support frames are used to support the first rotating shaft 31 . The embodiment of the present invention does not specifically limit the two support frames.

[0066] In one possible implementation, Figure 5 As shown, the battery cell loading device also includes a slope output device 60 and a second blocking device 70, wherein: the second input end 61 of the slope output device 60 is opposite to the first output end 21 of the power transmission device 20, and the second output end 62 of the slope output device 60 is lower than the second input end 61; the second blocking device 70 is located above the second output end, and the second blocking device 70 regulates the battery cells transported on the slope output device.

[0067] In a possible implementation, the second blocking device 70 includes: a second rotating shaft 71, a second linkage block 72, and a second shielding plate 73, wherein: (eg Figure 5 or Figure 6 As shown in FIG. 1 , the second rotating shaft 71 is located above the second output end 62 of the ramp output device 60, and the second shielding plate 73 is located on the side of the second rotating shaft 71 close to the second output end 62. The distance from the second shielding plate 73 to the ramp output device 60 is less than the diameter of the battery cell; Figure 6 As shown, the lower plane of the second rotating shaft 71 is fixedly connected to the upper plane of the second baffle plate 73; the lower plane of the second linking block 72 is fixedly connected to the upper plane of the second rotating shaft 71, and the end 74 of the second linking block 72 close to the second output end 62 is connected to the support frame base 75 of the second rotating shaft 71 through a second spring 76.

[0068] In actual implementation, Figure 6 As shown, the second blocking device 70 may be a symmetrical structure, and its symmetry axis is parallel to the conveying direction of the ramp output device 60. In addition, since the distance from the second shielding plate 73 to the ramp output device 60 is smaller than the diameter of the battery cell, the battery cell is blocked by the second shielding plate when passing under the second shielding plate 73, as shown in FIG. Figure 7As shown, the battery cell 82 behind the battery cell 81 pushes the battery cell 81 when the ramp output device 60 slides down, so that the cylindrical surface of the battery cell 81 is tightly blocked by the second baffle plate 73 with the largest contact area, thereby achieving the regularity of the battery cell 81 and allowing the battery cell 81 to be output from the second output end 62 of the ramp output device 60 in a preset posture.

[0069] In addition, the battery cell 71 passes under the second shielding plate in a preset posture under the impact of the battery cell 82, and is output from the second output end 62 of the ramp output device 60 in a preset posture. The cylindrical surface of the battery cell in the preset posture is parallel to the transmission direction of the ramp output device 60.

[0070] Moreover, when the battery cell passes under the second baffle plate 73, the second baffle plate 73 is lifted, thereby driving one end 74 of the second linkage block to be lifted; after the battery cell passes under the second baffle plate 73, the one end 74 of the second linkage block is driven by the return force of the second spring to reset the second baffle plate 73, so that the second baffle plate 73 can block a battery cell behind the passing battery cell.

[0071] It should be noted that the two support brackets of the second automatic device 70 are respectively arranged on both sides of the second output end 62 of the ramp output device 60. The two support brackets are used to support the second rotating shaft 71. This embodiment does not specifically limit the two support brackets.

[0072] In a possible implementation, the battery cell loading device also includes an adjustment device 90 for adjusting the inclination angle of the ramp output device 60, and the adjustment device 90 includes a lifting plate 91 and a supporting member 92, wherein: the upper plane of the lifting plate 91 is fixedly connected to the lower plane of the second input end 61 of the ramp output device 60; an end 93 of the lifting plate 91 close to the first output end is rotationally connected to the conveying motor 23 in the power transmission device 20; an end of the lifting plate 91 close to the second output end 62 is connected to the supporting member 92, and the inclination angle of the ramp output device 60 is changed by changing the posture of the supporting member 92.
