In the alignment device, during the alignment operation, firstly, the driving assembly drives the sliding base 13 to move along the first direction X through the first transmission structure 221 until the alignment assembly 12 is driven to move to the picking position, so that the alignment assembly 12 picks up the cap A3. Then, the driving assembly drives the transferring base 14 to move along the first preset direction B1 through the second transmission structure 223 until the aligning assembly 12 is driven to move from the picking position to the aligning position, so that the cap A3 on the aligning assembly 12 is aligned with the end of the steel shell A1. Finally, the alignment assembly 12 releases the cap A3 and returns to the initial position under the driving of the driving assembly.

So, compare with the needs of adopting a plurality of power supplies among the prior art, the utility model discloses an owing to first drive structure 221 and second drive structure 223's setting in the aligning device, realized utilizing a drive assembly can drive the slide 13 of counterpoint subassembly 12 and move respectively with carrying seat 13 and accomplish the action of counterpointing to reduce the quantity of power supply, simplified the structure, and reduced equipment cost.

Optionally, the sliding seat 13 is provided with a second sliding rail 132 extending lengthwise along the first preset direction B1, and the transferring seat 14 is provided with a second sliding block 141 sliding-engaged with the second sliding rail 132. In this way, the movement of the transfer base 14 in the first predetermined direction B1 with respect to the slide base 13 is guided by the sliding of the second slider 141 along the second slide rail 132.

Referring to fig. 6 to 7, in an embodiment, the driving assembly includes a driving shaft 211 and a rotary driving member (not shown). The driving shaft 211 is rotatably disposed with respect to the fixed base 11. The rotary drive is drivingly connected to the drive shaft 211 to drive the drive shaft 211 in rotation. Alternatively, the rotary drive may be an electric motor.

The driving shaft 211 is in transmission connection with the sliding seat 13 through a first transmission structure 221, so as to convert the rotation motion of the driving shaft 211 into the movement of the sliding seat 13 along the first direction X, i.e. to drive the sliding seat 13 to move along the first direction X. The driving shaft 211 is in transmission connection with the transferring base 14 through the second transmission structure 223, so as to convert the rotation motion of the driving shaft 211 into the movement of the transferring base 14 along the first preset direction B1, that is, to drive the transferring base 14 to move along the first preset direction B1.

In some embodiments, the first transmission structure 221 includes a first swing arm 2210, a first cam structure (not shown), and a first link structure (not shown). The first swing arm 2210 has a first end a1 and a second end a2. The first end a1 of the first swing arm 2210 is rotatably disposed relative to the fixing seat 11. A first cam structure is drivingly connected between the drive shaft 211 and the first swing arm 2210 to convert a rotational motion of the drive shaft 211 into a swinging motion of the first swing arm 2210 about its first end a1. The second end a2 of the first swing arm 2210 is drivingly connected to a first linkage structure, which is drivingly connected to the slider 13, so as to transform the swinging motion of the first swing arm 2210 into a movement of the slider 13 along the first direction X. Thus, the driving shaft 211 can rotate to drive the first swing arm 2210 to swing around the first end a1 through the first cam structure, and when the first swing arm 2210 swings around the first end a1, the first swing arm 2210 can drive the slide carriage 13 to move along the first direction X through the first link structure, so that the slide carriage 13 drives the alignment assembly 12 to move between the initial position and the pick-up position along the first direction X.

In particular embodiments, the first cam structure includes a first cam 2211 and a first roller 2211a. The first cam 2211 is mounted on the driving shaft 211 and rotates in synchronization with the driving shaft 211. The first roller 2211a is mounted on the first swing arm 2210 and is in rolling fit with the first cam 2211, so that the first cam 2211 drives the first swing arm 2210 to swing around the first end a1 through the first roller 2211a during the rotation process of the first cam 2210. Therefore, the driving shaft 211 is used to drive the first cam 2211 to rotate, when the first cam 2211 rotates, the first roller 2211a rolls along the first cam 2211, so as to drive the first roller 2211a to drive the first swing arm 2210 to swing around the first end a1, and further drive the sliding seat 13 to move along the first direction X through the first connecting rod structure.

It should be noted that the rotation motion of the first cam 2211 drives the first swing arm 2210 to periodically swing to drive the slide seat 13 to move along the first direction X, so as to drive the alignment assembly 12 to periodically move between the initial position and the pick-up position, which is beneficial to achieving continuous alignment operation and improving production efficiency.

Further, the first cam structure further includes a first elastic component 2217, one end of the first elastic component 2217 is connected to the second end a2 of the first swing arm 2210, and the other end is fixedly disposed on the opposite fixing seat 11, so that the first elastic component 2217 provides a pre-tightening force for making the first swing arm 2210 drive the first roller 2211a to keep abutting against the first cam 2211. In this way, the first elastic member 2217 is disposed such that the first roller 2211a can always contact with the first cam 2211, thereby ensuring that the first roller 2211a can drive the first swing arm 2210 to periodically swing during the rotation of the first cam 2211.

With continued reference to fig. 3 to 5, in an embodiment, the alignment mechanism 10 further includes a first guiding seat 2212 mounted on the sliding seat 13, such that the first guiding seat 2212 moves along with the sliding seat 13 along the first direction X. The first guide holder 2212 has a first guide groove d1 (see fig. 4), and the first guide groove d1 extends in a second direction Y intersecting the first direction X. Preferably, the second direction Y is perpendicular to the first direction X. Specifically, in the embodiment shown in fig. 3, the first direction X is a left-right direction, and the second direction Y is an up-down direction.

The first link structure includes a first link 2213, a first drive rod 2214, and a second roller 2216. The first link 2213 is rotatably disposed relative to the fixing base 11 and has a third end a3 and a fourth end a4. One end of the first driving rod 2214 is hinged to the second end a2 of the first swing arm 2210, and the other end of the first driving rod 2214 is hinged to the third end a3 of the first link 2213. The second roller 2216 is rotatably connected to the fourth end a4 of the first link 2213 and is in rolling engagement with the first guide groove d 1. Thus, when the alignment assembly 12 needs to be driven to move along the first direction X, the driving shaft 211 is controlled to rotate to drive the first cam 2211 to rotate, the first cam 2211 drives the first swing arm 2210 to swing around the first end a1 through the first roller 2211a, the first swing arm 2210 drives the first driving rod 2214 to move, the first driving rod 2214 drives the first link 2213 to rotate, the first link 2213 drives the second roller 2216 thereon to roll along the first guiding slot d1, so as to drive the first guiding seat 2212 and the sliding seat 13 to move together along the first direction X, and the sliding seat 13 drives the loading seat 14 and the alignment assembly 12 thereon to move between the initial position and the picking position along the first direction X.

In an embodiment, the position of the first guide seat 2212 relative to the sliding seat 13 in the first direction X is adjustable, so as to adjust the positions of the sliding seat 13 and the alignment assembly 12 in the first direction X, so as to use steel shells A1 with different specifications, thereby improving the compatibility of the equipment.

The first adjusting screw 2215 is rotatably connected to the slider 13 and is threadedly coupled to the first guide 2212. As such, when the position of the first guide holder 2212 needs to be adjusted, first, the locking member is loosened so that the first guide holder 2212 can move in the first direction X relative to the slider 13. Then, the first adjusting screw 2215 is screwed to drive the first guide holder 2212 to perform position adjustment in the first direction X relative to the slide base 13. When the position of the first guide holder 2212 is adjusted to the right position, the first adjusting screw 2215 is turned off, and the locking member is tightened to lock the first guide holder 2212 on the sliding base 13. Alternatively, the retaining member may be a retaining screw.

Referring to fig. 6 and 7, in some embodiments, the second transmission structure 223 includes a second swing arm 2230, a second cam structure (not shown), and a second link structure (not shown), and the second swing arm 2230 has a fifth end a5 and a sixth end a6. The fifth end a5 of the second swing arm 2230 is rotatably disposed relative to the fixed seat 11. The second cam structure is drivingly connected between the driving shaft 211 and the second swing arm 2230 to convert the rotational movement of the driving shaft 211 into the swinging movement of the second swing arm 2230 about the fifth end a 5. The second link structure is connected between the sixth end a6 of the second swing arm 2230 and the transfer seat 14 in a transmission manner, so as to convert the swing motion of the second swing arm 2230 into the movement of the transfer seat 14 along the first preset direction B1, and further drive the alignment assembly 12 to move between the pickup position and the alignment position along the first preset direction B1.

Optionally, the transmission assembly 22 further includes a mounting shaft F and a supporting seat, the supporting seat is relatively fixed to the fixing seat 11, and the mounting shaft F is fixedly mounted on the supporting seat. A first end a1 of the first swing arm 2210 is bearing-mounted on the mounting shaft F so that the first swing arm 2210 can swing around the mounting shaft F. The fifth end of the second swing arm 2230 may also be bearing mounted on this mounting shaft F, so that the second swing arm 2230 is also able to swing about the mounting shaft F.

Specifically, in the embodiment, the second cam structure includes a second cam 2231 and a third roller (not shown), and the second cam 2231 is mounted on the driving shaft 211 and rotates synchronously with the driving shaft 211, that is, the driving shaft 211 can drive the second cam 2231 to rotate synchronously when rotating. The third roller is installed on the second swing arm 2230 and is in rolling fit with the second cam 2231, so that the second cam 2231 drives the second swing arm 2230 to swing around the fifth end a5 through the third roller in the rotating process. Thus, the driving shaft 211 is used to drive the second cam 2231 to rotate, and when the second cam 2231 rotates, the third roller rolls along the second cam 2231, so as to drive the third roller to drive the second swing arm 2230 to swing around the fifth end a5, and further drive the moving seat 14 and the alignment assembly 12 on the moving seat 14 to move along the first predetermined direction B1 through the second link structure.

It should be noted that the second swing arm 2230 is driven by the rotation of the second cam 2231 to periodically swing, and the moving seat 14 is driven to move along the first preset direction B1, so as to drive the alignment assembly 12 to periodically move between the picking position and the alignment position, thereby facilitating the continuous alignment operation and improving the production efficiency.

Further, the second cam structure further includes a second elastic element 2239, one end of the second elastic element 2239 is connected to the sixth end a6 of the second swing arm 2230, and the other end of the second elastic element 2239 is fixed to the fixing seat 11, so that the second elastic element 2239 provides a pre-tightening force for the second swing arm 2230 to drive the third roller to keep abutting against the second cam 2231. In this way, the second elastic member 2239 enables the third roller to always keep abutting against the second cam 2231, so as to ensure that the third roller can drive the second swing arm 2230 to periodically swing during the rotation of the second cam 2231.

With continued reference to fig. 3 to fig. 5, in an embodiment, the alignment mechanism 10 further includes a second guiding seat 2232 mounted on the carriage 14, and the second guiding seat 2232 has a second guiding groove d2 extending along a second predetermined direction B2 intersecting the first predetermined direction B1.

The second link structure includes a second link 2233, a fourth roller 2234, a third guide 2235, a fifth roller (not shown), a fourth guide (not shown), a sixth roller E, and a second driving rod 2237. The second link 2233 is rotatably connected to the slider 13 and has a seventh end a7 and an eighth end a8. The fourth roller 2234 is rotatably connected to the eighth end a8 of the second link 2233 and is in rolling fit with the second guide slot d2, so that when the second link 2233 rotates, the fourth roller 2234 is driven to roll along the second guide slot d2, and the second guide 2232 and the transferring seat 14 are driven to move together along the first predetermined direction B1. The third guide seat 2235 is movably coupled to the slide base 13 in the second direction Y, and has a third guide groove (not shown) and a fourth guide groove d3 both extending in the first direction X. The fifth roller is rotatably connected to the seventh end a7 of the second link 2233 and is in rolling fit with the third guide groove, so that the sliding base 13 can be driven to move along the third guide groove when moving along the first direction X, and because the third guide groove also extends along the first direction X, the sliding base 13 cannot cause the second link 2233 to rotate when moving along the first direction X, and further cannot cause the transfer base 14 and the alignment assembly 12 to move along the first preset direction B1.

The fourth guide seat is movably disposed along the second direction Y relative to the fixed seat 11, the sixth roller E is rotatably connected to the fourth guide seat, and is in rolling fit with the fourth guide groove d3 of the third guide seat 2235, so that the sliding seat 13 can drive the sixth roller E to roll along the fourth guide groove d3 when moving along the first direction X, and because the fourth guide groove d3 also extends along the first direction X, the sliding seat 13 cannot cause the third guide seat 2235 to move along the second direction Y when moving along the first direction X, and cannot cause the second link 2233 to rotate, and further cannot cause the second guide seat 2232, the transfer seat 14, and the alignment assembly 12 to move along the first preset direction B1.

One end of the second driving rod 2237 is hinged to the sixth end a6 of the second swing arm 2230, and the other end of the second driving rod 2237 is hinged to the fourth guide seat. Thus, when the alignment assembly 12 needs to move along the first preset direction B1, the driving shaft 211 rotates to drive the second cam 2231 to rotate, the second cam 2231 drives the second swing arm 2230 to swing around the fifth end a5 through the third roller, the second swing arm 2230 drives the fourth guide seat to move along the second direction Y through the second driving rod 2237, the fourth guide seat drives the third guide seat 2235 to move along the second direction Y through the sixth roller E, the third guide seat 2235 drives the second connecting rod 2233 to rotate through the fifth roller, the second connecting rod 2233 drives the second guide seat 2232 to move along the first preset direction B1 through the fourth roller 2234, the second guide seat 2232 drives the transfer seat 14 and the alignment assembly 12 to move together along the first preset direction B1, so as to move the alignment assembly 12 between the pickup position and the alignment position.

Preferably, the central axis is parallel to the first direction X.

In this way, the at least two clamping jaws 121 are used for clamping the cap A3 together, so that the cap A3 is picked up at the picking position on the one hand, and the cap A3 is positioned on the other hand, that is, when the cap A3 is clamped, the center line of the cap A3 is collinear with the central axis surrounded by the at least two clamping jaws 121, and then when the alignment assembly 12 moves to the alignment position, the center line of the cap A3 is collinear with the center line of the steel shell A1, and at this time, the alignment of the cap A3 and the end of the steel shell A1 is completed. Preferably, the number of the jaws 121 is three.

In the specific embodiment, the alignment assembly 12 further has a positioning portion 122 located in the clamping space 124, and the positioning portion 122 is used for stopping the cap A3 entering the clamping space 124 in the first direction X, so as to position the cap A3 in the first direction X. In this way, during the process that the alignment assembly 12 moves toward the cap A3 along the first direction X, the cap A3 gradually enters the clamping space 124 between the at least two clamping jaws 121 (the at least two clamping jaws 121 are in the open state), until the cap A3 contacts the positioning portion 122 (i.e., the positioning portion 122 stops the cap A3), and at this time, the alignment assembly 12 is located at the picking position. Then, at least two jaws 121 clamp the cap A3 together, at which time the picking up of the cap A3 is completed.

Further, the aligning assembly 12 further includes a clamping jaw driving member 123, and the clamping jaw driving member 123 is fixedly installed on the transferring base 14 to move along with the transferring base 14. The jaw driver 123 has at least two driving ends, each of which has a jaw 121 mounted thereon, so that the jaw driver 123 can drive the respective jaw 121 to clamp or unclamp the cap A3. Alternatively, the jaw driver 123 may employ a jaw 121 cylinder.

Optionally, one side of each clamping jaw 121 facing the clamping space 124 is provided with a positioning surface matched with the circumferential surface of the cap A3, and the positioning surface of each clamping jaw 121 is attached to the circumferential surface of the cap A3 in the clamping state, so that the center line of the cap A3 is collinear with the central axis around which each clamping jaw 121 surrounds, and the positioning effect on the cap A3 is ensured.

Further, the outer peripheral surface of the cap A3 is a circumferential surface. The positioning surfaces of the clamping jaws 121 are all arc surfaces, and when the clamping jaws 121 are in a clamping state, the positioning surfaces of the clamping jaws 121 are located on the same circumferential surface, so that the clamping space 124 formed by jointly splicing is in a circular hole shape, that is, the outer circumferential surface of the cap A3 clamped by the clamping jaws 121 is tightly attached to the positioning surfaces of the clamping jaws 121, the central axis surrounded by the clamping jaws 121 and the central line of the cap A3 are ensured to be collinear, and the cap A3 is accurately positioned.

It should be noted that, in some cases, both ends of the steel shell A1 may have openings, both ends of the electric core are welded with the current collecting plates A2, and the two current collecting plates A2 respectively extend out of the steel shell A1 through the openings at both ends of the steel shell A1. The two caps A3 are respectively welded at the end parts of the two current collecting discs A2 extending out of the steel shell A1, and the two caps A3 extend towards the lower part of the steel shell A1. Therefore, in order to weld the two caps A3 to the two ends of the steel shell A1, respectively, it is necessary to move the two caps A3 to positions aligned with the two ends of the steel shell A1, respectively. Referring to fig. 3, fig. 4, fig. 6 and fig. 7, in an embodiment of the present invention, the two aligning mechanisms 10 are disposed oppositely along the first direction X, so that an aligning station F for the steel shell A1 to pass through is formed between the aligning assemblies 12 of the two aligning mechanisms 10. The number of the transmission assemblies 22 is two, and the two transmission assemblies 22 correspond to the two aligning mechanisms 10 one by one. The driving shafts 211 include two driving shafts 211, and the two driving shafts 211 rotate synchronously and correspond to the two aligning mechanisms 10 one to one. The first transmission structure 221 of each transmission assembly 22 is in transmission connection between the corresponding driving shaft 211 and the slide seat 13 of the alignment mechanism 10, and the second transmission structure 223 of each transmission assembly 22 is in transmission connection between the corresponding driving shaft 211 and the transfer seat 14 of the alignment mechanism 10.

In this way, the rotation motion output by one of the driving shafts 211 is converted into the movement of the slide 13 of one of the alignment mechanisms 10 along the first direction X by the first transmission structure 221, and is converted into the movement of the carriage 14 of the alignment mechanism 10 along the first preset direction B1 by the second transmission structure 223. The rotary motion output by the other driving shaft 211 is converted into the movement of the slide base 13 of the other alignment mechanism 10 along the first direction X by the first transmission structure 221, and is converted into the movement of the carriage 14 of the alignment mechanism 10 along the first preset direction B1 by the second transmission structure 223. That is to say, the two driving shafts 211 are used to respectively drive the aligning assemblies 12 of the two aligning mechanisms 10 to align the caps A3 at the two ends of the steel shell A1.

It should be noted that, in this embodiment, the driving assembly utilizes the two driving shafts 211 that rotate synchronously to drive the aligning assemblies 12 of the two aligning mechanisms 10 to align the two caps A3, so as to avoid configuring two driving assemblies to drive the aligning assemblies 12 of the two aligning mechanisms 10 to move, further reduce the number of power sources, facilitate simplifying the structure, and reduce the equipment cost.

It can be understood that, since the alignment assemblies 12 of the two alignment mechanisms 10 respectively pick up different caps A3 and bring the picked caps A3 into alignment with different ends of the steel shell A1, the respective picking positions and alignment positions of the alignment assemblies 12 of the two alignment mechanisms 10 are different. Therefore, it cannot be understood that the aligning assemblies 12 of the two aligning mechanisms 10 pick up the caps A3 at the same picking position, and align with the end of the steel shell A1 at the same position. It should be understood that the pick-up positions of the aligning members 12 of the two aligning mechanisms 10 are different, and the aligning positions of the aligning members 12 of the two aligning mechanisms 10 are also different.

Specifically, in the embodiment shown in fig. 3, the first direction X is a left-right direction, the first predetermined direction B1 of the alignment component 12 of the left alignment mechanism 10 is a rightward and upward inclined direction, and the first predetermined direction B1 of the alignment component 12 of the right alignment mechanism 10 is a leftward and upward inclined direction. During the alignment process, initially, the alignment assemblies 12 of the two alignment mechanisms 10 are located at their initial positions. First, the driving assembly drives the aligning assembly 12 of the left aligning mechanism 10 and the aligning assembly 12 of the right aligning mechanism 10 to approach each other until reaching the respective picking positions, so that the aligning assembly 12 of the left aligning mechanism 10 picks up the left cap A3 (see fig. 1) at its own picking position, and the aligning assembly 12 of the right aligning mechanism 10 picks up the right cap A3 (see fig. 1) at its own picking position. Then, the driving assembly drives the alignment assembly 12 of the left alignment mechanism 10 to move towards the left end of the steel shell A1 along a rightward and upward tilting direction (i.e. the first preset direction B1 of the alignment assembly 12 of the left alignment mechanism 10) until reaching the alignment position of the left end of the steel shell a, so that the cap A3 on the alignment assembly 12 of the left alignment mechanism 10 is aligned with the left end of the steel shell A1; meanwhile, the driving component drives the alignment component 12 of the alignment mechanism 10 on the right side to move towards the right end of the steel shell A1 along the leftward and upward inclined direction (i.e. the first preset direction B1 of the alignment component 12 of the alignment mechanism 10 on the right side) until reaching the alignment position of the right end of the steel shell A1, so that the caps A3 on the alignment component 12 of the alignment mechanism 10 on the right side are aligned with the right end of the steel shell A1, and at this time, the alignment processing of the two caps A3 at the two ends of the steel shell A1 and the two ends of the steel shell A1 respectively is completed.

In particular embodiments, the driving assembly further comprises a third transmission structure, which is drivingly connected between the two driving shafts 211, such that when one of the driving shafts 211 rotates, the other of the driving shafts 211 also rotates synchronously. The rotary drive member is drivingly connected to either of the two drive shafts 211, such that when the rotary drive member drives the drive shaft 211 to which it is drivingly connected to rotate, the other drive shaft 211 is also able to rotate synchronously. Alternatively, the third transmission structure may be a belt transmission structure, a gear transmission structure, a chain transmission structure, or the like, as long as the simultaneous rotation of the two driving shafts 211 can be realized, which is not limited herein.

Specifically, in the embodiment, the alignment device further comprises a conveying line for conveying the steel shell A1, a battery cell is contained in the steel shell A1, current collecting discs A2 are connected to two ends of the battery cell, and the two current collecting discs A2 extend out of the steel shell A1 from openings at two ends of the steel shell A1 and are connected with caps A3. The steel shell A1 is conveyed by the conveying line to pass through the aligning station F. When the steel shell A1 reaches the alignment station F, the alignment assemblies 12 of the two alignment mechanisms 10 respectively perform alignment treatment on the two caps A3 at the two ends of the steel shell A1. Therefore, the steel shells A1 are continuously aligned through the alignment station F under the conveying action of the conveying line, and the alignment treatment is favorably improved. Alternatively, the conveyor line may be a belt conveyor line, or may be another type of conveyor line, which is not limited herein.

Referring to fig. 5, in an embodiment, a plurality of alignment assemblies 12 are disposed on the transfer base 14 of each alignment mechanism 10, wherein the plurality of alignment assemblies 12 on the transfer base 14 of one alignment mechanism 10 correspond to the plurality of alignment assemblies 12 on the transfer base 14 of another alignment mechanism 10 one by one.
