Description

Technical Field

[0001] This invention belongs to the field of battery production line technology, and specifically relates to a battery connection mechanism. Background Technology

[0002] With the development of technology, batteries are used in more and more fields, and the market demand for batteries is gradually increasing. While increasing battery production, it is also necessary to ensure the output of high-quality batteries.

[0003] Traditional cleaning machines often experience battery buffer buildup before battery connection, causing batteries to bump and squeeze against each other in the channel, resulting in scratches or dents on the battery surface and affecting the battery yield. Summary of the Invention

[0004] The purpose of this invention is to provide a battery connection mechanism to solve one or more technical problems existing in the prior art.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: This invention discloses a battery connection mechanism, comprising: A rotating assembly includes a rotating shaft that is pulsatorically connected to a drive assembly, a fixed shaft seat that is rotatably connected to a base and fixedly fixed thereto, and a fixed cam connected to the fixed shaft seat, the fixed cam having a cam groove. A central turntable, which is coaxially connected to the rotation shaft, and the central turntable is provided with a plurality of central fixtures arranged in a circular pattern along its edge; A floating turntable is coaxially connected to the rotating shaft. The floating turntable has multiple floating fixtures arranged in a circle along its edge. The floating fixtures are movably connected to the floating turntable and are slidably connected to the cam groove. The battery connection mechanism is configured to include a first connection end and a second connection end. When the floating turntable rotates relative to the fixed cam, the floating turntable drives multiple floating fixtures to perform circular motion, and the floating fixtures slide along the cam groove and perform circular motion relative to the floating turntable, so that the floating fixtures corresponding to the first connection end and the center fixture are arranged in a straight line in the vertical direction, and the floating fixtures corresponding to the second connection end and the center fixture are arranged in an alternating manner.

[0006] The present invention has at least the following beneficial effects: the floating fixture and the central fixture corresponding to the first docking end are arranged in a straight line in the vertical direction, so that the battery docking mechanism can neatly and orderly input or output multiple batteries at the first docking end through the floating fixture and the central fixture.

[0007] The floating fixture and the central fixture corresponding to the second docking end are arranged in an alternating manner, so that the battery docking mechanism can output or input multiple batteries at the second docking end in a staggered manner through the floating fixture and the central fixture.

[0008] The drive component drives the rotating shaft to rotate, which in turn drives the central turntable and floating turntable, which are coaxially connected to the rotating shaft, to rotate. This, in turn, drives multiple central fixtures and multiple floating fixtures to move in a circular motion around the rotating shaft, thereby realizing the transfer of the battery between the first and second connection ends.

[0009] The rotating shaft is rotatably connected to a fixed shaft seat that is fixed relative to the machine base. The fixed shaft seat is connected to a fixed cam, and the fixed cam has a cam groove. The floating fixture is movably connected to the floating turntable, and the floating fixture is slidably connected to the cam groove. Therefore, while the floating turntable drives multiple floating fixtures to make circular motion, the floating fixture slides along the cam groove and makes circular motion relative to the floating fixture, realizing the transformation between the floating fixture and the center fixture in a straight line arrangement and an alternating arrangement.

[0010] When multiple batteries are input in a straight line at the first docking end, the battery docking mechanism can arrange them in a staggered, stepped manner according to the requirements of the subsequent docking station, so as to output the batteries at the second docking end; when multiple batteries are input in an alternating manner at the second docking end, the battery docking mechanism can arrange the multiple batteries in a straight line and then dock them with the subsequent station at the first docking end for output.

[0011] By rearranging multiple batteries, battery buffering is prevented from piling up. A battery connection mechanism replaces the existing buffer channel, avoiding scratches or dents caused by batteries squeezing or colliding within the buffer channel, thus improving battery yield. Furthermore, the battery connection mechanism enables rapid, continuous, and precise battery handling, allowing the first and second connection ends of the batteries to be arranged in different configurations, providing transitional transport for multi-channel cleaning and unloading or turret merging and splitting.

[0012] As a further improvement to the above technical solution, the floating fixture is rotatably connected with a first meshing member and a second meshing member, the first meshing member and the second meshing member are connected in a transmission manner, the first meshing member meshes with the floating turntable, and the floating fixture is slidably connected with a third meshing member, one end of the third meshing member meshes with the second meshing member, and the other end of the third meshing member is engaged in the cam groove.

[0013] As a further improvement to the above technical solution, the floating turntable is connected to a plurality of fixed gears arranged circumferentially with the rotating shaft as the array center. The meshing end of the fixed gear extends circumferentially with the axis of the rotating shaft as the center. The first meshing member is a movable gear, which meshes with the fixed gear.

[0014] As a further improvement to the above technical solution, the second meshing member is an interlocking gear that meshes with the movable gear, and the third meshing member is a rack extending radially along the rotation axis. The rack and the floating fixture are connected by a guide rail.

[0015] As a further improvement to the above technical solution, the floating fixture is rotatably connected with a first transmission tooth and a second transmission tooth that are meshed together. The first transmission tooth is coaxially connected to the movable gear, and the second transmission tooth is coaxially connected to the interlocking gear.

[0016] As a further improvement to the above technical solution, the floating turntable is provided with a plurality of circumferentially extending limiting grooves along its edge, and the plurality of limiting grooves correspond one-to-one with the plurality of floating fixtures, and the floating fixtures are connected to support members that pass through the limiting grooves.

[0017] As a further improvement to the above technical solution, two fixed shaft seats and two fixed cams are provided, with the two cam grooves facing the central turntable. Two floating turntables are provided and are located above and below the central turntable, respectively. The central fixture corresponding to the second docking end is located between the two floating fixtures corresponding to the second docking end in the vertical projection.

[0018] As a further improvement to the above technical solution, the shapes of the two fixed cams are aligned vertically, the vertex of the fixed cam corresponds to the first connecting end, and the minimum radius of the profile of the fixed cam corresponds to the second connecting end.

[0019] As a further improvement to the above technical solution, the arrangement direction of the upper interlocking gear and the rack is opposite to that of the lower interlocking gear and the rack.

[0020] As a further improvement to the above technical solution, the first connecting end and the second connecting end are the two ends of a horizontal straight line passing through the axis of rotation. Attached Figure Description

[0028] In existing technology, multiple batteries in a buffer channel are fed by a feeding machine, with adjacent batteries being fed sequentially through mutual collision and compression. However, the collision and compression between adjacent batteries can cause scratches or dents on the battery surface, affecting battery quality.

[0029] Reference Figures 1 to 4 Several embodiments of the battery connection mechanism of the present invention are given below.

[0030] like Figures 1 to 4 As shown, the battery connection mechanism 100 of this embodiment includes a rotating component, a central turntable 400 and a floating turntable 500.

[0031] It is understood that the rotating assembly includes a rotating shaft 200, such as Figures 1 to 4 As shown, the rotating shaft 200 is connected to an external drive assembly, which drives the rotating shaft 200 to rotate relative to the machine base. A fixed bearing 300 is fitted over the rotating shaft 200, and the two are rotatably connected. Figure 1 and Figure 2 As shown, the fixed shaft seat 300 is connected to the machine base, so that the two are relatively fixed. Therefore, the fixed shaft seat 300 can not only provide support for the rotating shaft 200, but also avoid interfering with the rotational movement of the rotating shaft 200.

[0032] It is understandable that the fixed shaft seat 300 is connected to a fixed cam 310, and the fixed cam 310 has a cam groove 311 along its edge, such as... Figure 1 and Figure 3 As shown. The cam groove 311 is a horizontal annular groove with one end protruding outward.

[0033] It is understandable that the central turntable 400 is mounted on the rotating shaft 200, and the two are coaxially connected. Multiple central fixtures 410 are provided along the edge of the central turntable 400, such as... Figure 1 and Figure 2 As shown, multiple center fixtures 410 are arranged circumferentially with the axis of the rotation shaft 200 as the array center, that is, the multiple center fixtures 410 are arranged in a circle, and the included angle between any two adjacent center fixtures 410 is the same. Thus, when the rotation shaft 200 rotates, it drives the central turntable 400 to rotate, which in turn drives the multiple center fixtures 410 to perform circular motion.

[0034] Understandably, the floating turntable 500 is also mounted on the rotating shaft 200, and the two are coaxially connected. The floating turntable 500 has multiple floating fixtures 510 along its edge, such as... Figures 1 to 3As shown, multiple floating fixtures 510 are arranged circumferentially around the axis of the rotation shaft 200. The floating fixtures 510 are movably connected to the floating turntable 500 and slidably connected to the cam groove 311. With this configuration, when the drive assembly drives the rotation shaft 200 to rotate, the rotation shaft 200 drives the central turntable 400 and the floating turntable 500 to rotate. The central turntable 400 drives multiple central fixtures 410 to rotate in a circular motion, and the floating turntable 500 drives multiple floating fixtures 510 to rotate in a circular motion. At this time, the floating fixtures 510, driven by the floating turntable 500 to rotate in a circular motion, slide along the cam groove 311 and rotate relative to the floating turntable 500, thereby changing the relative position of the floating fixtures 510 and the floating turntable 500.

[0035] In addition, the battery connection mechanism 100 also includes a first connection end 110 and a second connection end 120 for conveying cylindrical batteries, such as Figure 4 As shown. When the rotating shaft 200 drives the central fixture 410 and the floating fixture 510 to rotate to the first connecting end 110, the central fixture 410 and the floating fixture 510 are arranged in a straight line in the vertical direction, that is, the central fixture 410 and the floating fixture 510 at the first connecting end 110 are aligned vertically, as shown. Figure 4 As shown, with the rotation of the rotating shaft 200, the angle between the central fixture 410 and the floating fixture 510 gradually increases in the upper and lower projections. When the central fixture 410 and the floating fixture 510 rotate to the second connecting end 120, the central fixture 410 and the floating fixture 510 are arranged in an alternating pattern, as shown. Figure 4 As shown.

[0036] In some embodiments, multiple cylindrical batteries are arranged in a straight line and input into the battery connection mechanism 100 at the first connection end 110, and then output to the docking station at the second connection end 120 in an alternating arrangement. After the battery handover is completed, the rotating shaft 200 rotates again, and the corresponding central fixture 410 and floating fixture 510 rotate back to the first connection end 110 and are arranged in a straight line for feeding again.

[0037] In other embodiments, multiple cylindrical batteries are input at the second docking end 120 in an alternating arrangement, and then output at the first docking end 110 in a straight line arrangement to the docking station. After the battery handover is completed, the rotating shaft 200 rotates again, and the corresponding central fixture 410 and floating fixture 510 rotate back to the second docking end 120 and are fed again in an alternating arrangement.

[0038] In this way, the battery connection mechanism 100 can quickly, continuously and accurately carry out the handling of steel-cased batteries, realizing the arrangement of batteries in different forms during the transportation and handover process. It provides transitional transportation for multi-channel cleaning and unloading or turret splitting and merging. During the transportation process, the batteries correspond one-to-one with the central fixture 410 or floating fixture 510, avoiding scratches or bumps to the batteries in the buffer channel and improving the yield of batteries.

[0039] Understandably, the central fixture 410 and the floating fixture 510 clamp the battery from the fixture, thereby completing the battery input.

[0040] It is understandable that the floating fixture 510 is rotatably connected to a first meshing member and a second meshing member. The first meshing member is meshed with the floating turntable 500, and the first and second meshing members are connected by transmission. Therefore, the floating fixture 510 and the floating turntable 500 are movably connected, which is actually a meshing connection between the floating fixture 510 and the floating turntable 500.

[0041] It is understandable that the floating fixture 510 is slidably connected to a third engaging member, one end of which engages with the second engaging member. Therefore, the slidable connection between the floating fixture 510 and the cam groove 311 is actually achieved by the other end of the third engaging member, which is slidably connected to the floating fixture 510, being engaged within the cam groove 311.

[0042] With this configuration, when the floating turntable 500 drives multiple floating fixtures 510 to perform circular motion, one end of the third meshing member slides relative to the floating fixture 510 as the circularly moving floating fixture 510 slides within the cam groove 311, thereby driving the second meshing member to rotate relative to the floating fixture 510. Since the first and second meshing members are connected by a transmission, the rotating second meshing member drives the first meshing member to rotate relative to the floating fixture 510. Because the first meshing member is engaged with the floating fixture 510, the first meshing member, rotating relative to the floating fixture 510, moves along the floating turntable 500, thereby achieving relative circular motion between the floating fixture 510 and the floating turntable 500, changing the relative position between the floating fixture 510 and the floating turntable 500, and thus causing the floating fixture 510 and the central fixture 410 to be staggered at the second connecting end 120.

[0043] It is understandable that, on the rotation path of the floating fixture 510 from the second docking end 120 to the first docking end 110, the third meshing member slides along the cam groove 311 and slides in the opposite direction relative to the floating fixture 510. At this time, the relative circumferential motion direction between the floating fixture 510 and the floating turntable 500 from the second docking end 120 to the first docking end 110 is opposite to the relative circumferential motion direction between the first docking end 110 and the second docking end 120. The floating fixture 510, which is staggered with the central fixture 410, returns to the first docking end 110 with the circumferential motion of the floating fixture 510, and also makes a circumferential motion relative to the floating fixture 510 and gradually approaches the central fixture 410, thereby realizing that the floating fixture 510 and the central fixture 410 are arranged in a line above and below the first docking end 110.

[0044] It is understandable that the floating turntable 500 is connected to multiple fixed gears 520 arranged circumferentially with the rotation axis 200 as the array center, such as... Figure 1 and Figure 3 As shown, the fixed gears 520 and the floating fixture 510 correspond one-to-one, and the included angle between any two adjacent fixed gears 520 is equal. The meshing ends 521 of the multiple fixed gears 520 extend in an arc with the axis of the rotating shaft 200 as the center and with the same radius, as shown. Figure 3 As shown. The first meshing element is a movable gear 610, which meshes with the fixed gear 520, as follows. Figure 1 and Figure 3 As shown, when the rotating sliding gear moves relative to the meshing end 521 of the fixed gear 520, it drives the floating fixture 510 to make a circular motion relative to the floating turntable 500 with the axis of the rotating shaft 200 as the center.

[0045] In this embodiment, the fixed gear 520 has sector teeth, and the meshing end 521 of the fixed gear 520 is the arc edge of the sector teeth, such as... Figure 3 As shown, the fixed gear 520 is fixed to the floating turntable 500 by bolts. The movable gear 610 is rotatably connected to the floating fixture 510 via bearings.

[0046] It is understandable that the transmission connection between the first and second meshing components is actually a meshing connection. The second meshing component is an interlocking gear 620 that meshes with the movable gear 610. Through their meshing, the rotating interlocking gear 620 can drive the movable gear 610 to rotate. The third meshing component is a rack 630, and the rack 630 extends in the radial direction of the rotating shaft 200, such as... Figure 1 and Figure 4 As shown.

[0047] Thus, when the floating fixture 510 is driven by the floating turntable 500 to perform circular motion, since the rotating shaft 200 is coaxial with the floating turntable 500, the rack 630, which slides along the cam groove 311, also moves radially along the floating turntable 500, thereby driving the interlaced gear 620 to rotate. The rack 630 and the floating fixture 510 are connected by a guide rail 640, which extends in the radial direction of the floating turntable 500, guiding the relative sliding of the rack 630 and the floating fixture 510.

[0048] Understandably, to avoid interference between the meshing of the fixed gear 520 and the movable gear 610 and the meshing of the interlocking gear 620 and the rack 630, the floating fixture 510 is rotatably connected with a first transmission gear 710 and a second transmission gear 720, such as... Figure 1 As shown. Specifically, the first transmission gear 710 is coaxially connected to the movable gear 610, as shown. Figure 1 As shown; the second transmission gear 720 is coaxially connected to the interlocking gear 620, as... Figure 4 As shown. The first transmission gear 710 and the second transmission gear 720 are meshed together. The meshing connection between the movable gear 610 and the interlocking gear 620 is actually the meshing connection between the first transmission gear 710 and the second transmission gear 720.

[0049] With this configuration, the meshing positions of the fixed gear 520 and the movable gear 610, the meshing positions of the first transmission gear 710 and the second transmission gear 720, and the meshing positions of the interleaved gear 620 and the rack 630 are located at different heights. This configuration enables the transmission of the movable gear 610 and the interleaved gear 620 while avoiding interference. Furthermore, it allows the use of the vertical space of the floating fixture 510 to install components such as the movable gear 610, preventing insufficient horizontal space on the floating turntable 500, which would reduce the number of floating fixtures 510 connected to the floating turntable 500 and affect the efficiency of the connecting and conveying process.

[0050] Understandably, the floating fixture 510 is also slidably connected to the floating turntable 500 to guide the circular motion of the floating fixture 510 relative to the floating turntable 500 and prevent deviation. Specifically, the floating turntable 500 has multiple limiting grooves 530 along its circumferential edge, such as... Figure 1 and Figure 3 As shown, the number of limiting grooves 530 is the same as the number of floating fixtures 510. The limiting grooves 530 extend in the vertical direction and connect the upper and lower end faces of the floating turntable 500. Multiple limiting grooves 530 are arranged circumferentially with the axis of the rotation shaft 200 as the array center. The limiting grooves 530 also extend in an arc with the axis of the rotation shaft 200 as the center. The floating fixture 510 is connected to a support member, which extends in the vertical direction. The middle part of the support member passes through the limiting groove 530, and both the upper and lower ends of the support member are connected to the floating fixture 510.

[0051] Thus, when the floating fixture 510 moves in a circular motion relative to the floating turntable 500, the support member moves within the arc-extended limiting groove 530, thereby guiding the movement of the floating fixture 510. Furthermore, the support member also supports the floating fixture 510, preventing it from falling off the floating turntable 500, and ensuring that the movable gear 610 of the floating fixture 510 remains engaged with the meshing end 521 of the fixed gear 520.

[0052] Understandably, the support member can be connected to the floating fixture 510 by screws or bolts. Both ends of the support member are respectively connected to the inner groove surface of the limiting slide 530 to stably support the floating fixture 510.

[0053] In this embodiment, two fixed bearing seats 300, two fixed cams 310, and two floating turntables 500 are provided, such as... Figure 1 and Figure 2 As shown. A floating turntable 500 is connected to four floating fixtures 510, as follows. Figure 3 As shown. The central turntable 400 has four central fixtures 410, as... Figure 4 As shown.

[0054] It is understandable that the two fixed bearing seats 300 are respectively fitted onto the upper and lower ends of the rotating shaft 200 and are respectively connected and fixed to the machine base, and the central turntable 400 is located between the two fixed bearing seats 300.

[0055] Understandably, the two fixed cams 310 are arranged vertically. The upper fixed cam 310 is connected and fixed to the lower end of the upper fixed shaft seat 300, and its cam groove 311 is set towards the central turntable 400, that is, the opening of the cam groove 311 is set downward. The lower fixed cam 310 is connected and fixed to the upper end of the lower fixed shaft seat 300, and its cam groove 311 is set towards the central turntable 400, that is, the opening of the cam groove 311 is set upward.

[0056] Understandably, the two floating turntables 500 are located above and below the central turntable 400, respectively. The rack 630 of the upper floating turntable 500 is engaged in the upper cam groove 311, and the rack 630 of the lower floating turntable 500 is engaged in the lower cam groove 311. The central fixture 410 corresponding to the first connecting end 110 is located between the two floating fixtures 510 corresponding to the first connecting end 110 in the vertical direction. The central fixture 410 corresponding to the second connecting end 120 is located between the two floating fixtures 510 corresponding to the second connecting end 120 in the vertical projection.

[0057] It is understandable that the shapes of the two fixed cams 310 are aligned vertically. Specifically, the vertex of the fixed cam 310 is located at the first connecting end 110, and the minimum radius of the profile of the fixed cam 310 is located at the second connecting end 120. Figure 4 As shown, the cam groove 311 is provided along the horizontal wall of the fixed cam 310. Thus, when the floating fixture 510 drives the battery to rotate from the first connection end 110 to the second connection end 120, the rack 630 corresponding to the floating fixture 510 slides in the cam groove 311 with a gradually decreasing radius; when the floating fixture 510 rotates from the second connection end 120 to the first connection end 110, the rack 630 corresponding to the floating fixture 510 slides in the cam groove 311 with a gradually increasing radius.

[0058] It is understandable that the arrangement direction of the upper interlocking gear 620 and rack 630 is opposite to that of the lower interlocking gear 620 and rack 630.

[0059] Thus, when the rotating shaft 200 rotates, the two floating turntables 500 rotate in the same direction. The direction in which the upper rack 630 drives the interlaced gear 620 to rotate is opposite to the direction in which the lower rack 630 drives the interlaced gear 620 to rotate. This causes the two corresponding floating fixtures 510 to rotate in opposite directions relative to the two corresponding floating turntables 500. Therefore, the rotation amplitude of one floating fixture 510 will be greater than that of the corresponding central fixture 410, and the rotation amplitude of the other floating fixture 510 will be less than that of the corresponding central fixture 410. This achieves an interlaced arrangement of the two floating fixtures 510 and the central fixture 410 corresponding to the second connecting end 120.

[0060] In this embodiment, the upper interlocking gear 620 and rack 630 are arranged in opposite directions to the rotation direction of the rotating shaft 200, while the lower interlocking gear 620 and rack 630 are arranged in the rotation direction of the rotating shaft 200.

[0061] It is understandable that the two corresponding limiting grooves 530 have overlapping ends in the vertical direction, and the two support members of the two floating fixtures 510 corresponding to the first connecting end 110 are located at the overlapping ends, ensuring that the two floating fixtures 510 are vertically aligned. The two support members of the two floating fixtures 510 corresponding to the second connecting end 120 are located at the end of the two limiting grooves 530 away from the overlapping ends. At this time, the distance between the two vertically corresponding floating fixtures 510 is the largest.

[0062] It is understood that the first connection end 110 and the second connection end 120 are the two ends of a horizontal straight line passing through the axis of the rotating shaft 200. When the rotating shaft 200 rotates 180 degrees, the floating fixture 510 and the central fixture 410 can be switched between the first connection end 110 and the second connection end 120 to realize the transport of multiple batteries. The included angle between two adjacent central fixtures 410 in the central turntable 400 is 90 degrees.

[0063] It is understood that both the floating fixture 510 and the central fixture 410 include clamping ends for holding the battery. This invention does not improve the structure of the clamping ends of the floating fixture 510 and the central fixture 410. Therefore, those skilled in the art should understand the specific structure and working principle of the clamping ends, which will not be explained in detail here.

[0064] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
