Description

Technical Field

[0001] The utility model relates to a sealing machine, in particular to a steel ball sealing machine for batteries. Background Art

[0002] After injecting liquid into the battery, it is usually necessary to seal the liquid injection port. A common method is to use a sealing machine to install steel balls at the liquid injection port of the battery to achieve the effect of plugging. For example, Chinese Utility Model CN201038199Y discloses a sealing device for an automatic battery sealing machine. The sealing device is provided with a pusher moving plate electrode connected to a feeding driver and a positioning clamping moving plate electrode connected to a positioning driver. The two electrodes are used to clamp the battery to form precise positioning. After positioning, a thimble is used to suck the steel ball and install it into the liquid injection port of the battery.

[0003] However, the above method of installing steel balls has the problem that the steel balls are not stably sucked and may fall off. In this regard, a sealing device for steel ball conveying and pressing into a lithium-ion battery disclosed in Chinese Utility Model Application CN101038956A has a ball holding cavity on the upper template, a steel ball inlet hole on the lower template, and a sliding plate between the upper template and the lower template. The steel ball (i.e., the steel ball) falls from the ball holding cavity into the ball transfer hole of the sliding plate, and the steel ball is transferred to the steel ball inlet hole by moving the sliding plate, and the steel ball is pressed into the liquid injection port of the battery by a needle hammer.

[0004] However, since the battery needs to be positioned before installing the steel ball, the positioning process will cause extrusion to the battery, and when the battery is extruded, its electrolyte will overflow through the liquid injection port, thereby polluting the needle hammer, the ball holding cavity and even the outside of the sealing machine.

[0005] In addition, as Figure 1 shown, the ear 102 of the existing battery 100 is located on the upper surface of the battery 100 and near the liquid outlet 101, resulting in that the steel ball inlet hole of the sealing device disclosed in Chinese Utility Model Application CN101038956A cannot be close to the liquid outlet 101, that is, the steel ball cannot be smoothly pressed into the liquid outlet 101.

[0006] In addition, the sealing device disclosed in Chinese Utility Model CN201038199Y uses a pusher moving plate electrode to push the next battery to be sealed to move and push the previously sealed battery to the discharge port. During this process, the two batteries will collide. Most of the side walls of the existing battery 100 are made of aluminum alloy material, and the hardness of the aluminum alloy is relatively small, while the force of the driver is usually large and the speed is usually fast. The above collision process is likely to cause damage to the side wall of the battery 100. Summary of the Utility Model

[0007] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the present utility model is to design a steel ball sealer for batteries, which can block the electrolyte overflowing from the liquid outlet during battery positioning, thereby avoiding the pollution problem caused by electrolyte overflow.

[0008] To achieve the above object, the present utility model provides a steel ball sealer for batteries, comprising: a feeding device, a transfer and positioning device, a sealing device and a discharging device, wherein the transfer range of the transfer and positioning device covers the feeding device, the sealing device and the discharging device;

[0009] The sealing device includes: a steel ball input mechanism, a transfer block, a sliding propulsion mechanism and a top ball propulsion mechanism. The transfer block is provided with a transfer channel and an output channel. The transfer channel is provided with a steel ball input position and a steel ball output position, and the upper port of the output channel is located directly below the steel ball output position;

[0010] The steel ball input mechanism is communicated with the transfer block to transfer steel balls to the steel ball input position;

[0011] The sliding propulsion mechanism includes: a sliding plate and a sliding driver. The sliding plate is inserted into the transfer channel. The sliding plate is provided with a steel ball hole, and the sliding driver is connected to the sliding plate to drive the steel ball hole to move between the steel ball input position and the steel ball output position;

[0012] The top ball propulsion mechanism includes: a top pin and a top ball driver. The top ball driver is connected to the top pin to drive the top pin to move and press the steel ball from the steel ball output position through the output channel into the liquid injection port of the battery;

[0013] When the steel ball hole is located at the steel ball input position, the sliding plate blocks the output channel.

[0014] Furthermore, the steel ball input mechanism includes: an input pipe and a containing box. The input pipe is communicated with the containing box, and the input pipe extends from the containing box to the steel ball input position of the transfer block. Among them, the setting of the containing box can contain a large number of steel balls to meet the sealing operation of a large number of batteries.

[0015] Furthermore, the transfer block is further provided with a limiting channel and a guiding channel. The input pipe is inserted into the limiting channel, and the top pin is inserted into the guiding channel. Among them, the setting of the limiting channel can limit the position of the input pipe to enable the steel ball to accurately enter the steel ball input position; the setting of the guiding channel can play a guiding role for the top pin to ensure that the top pin accurately pushes the steel ball.

[0016] Further, the sealing device further includes: a vertical adjustment mechanism, a bracket, and a horizontal adjustment mechanism. The transfer block and the sliding propulsion mechanism are both disposed on the vertical adjustment mechanism to adjust the vertical position of the transfer block. The top bead propulsion mechanism and the vertical adjustment mechanism are both disposed on the bracket, and the bracket is disposed on the horizontal adjustment mechanism to adjust the horizontal position of the transfer block. Among them, the vertical adjustment mechanism and the horizontal adjustment mechanism are provided to adjust the three-dimensional position of the transfer block, so that the steel ball sealing machine can be applicable to batteries of different models (i.e., different sizes).

[0017] Further, the feeding device includes: a motor, a plurality of belt shafts, a belt, and a feeding stopper. The motor is connected to one of the belt shafts, the belt is wound around the plurality of belt shafts, the feeding stopper is located on the belt, and the feeding stopper is provided with a vertical surface for fitting the battery. Among them, the feeding stopper is provided to maintain the battery on the belt in a vertical state for subsequent transfer and positioning operations.

[0018] Further, the transfer and positioning mechanism includes: a transfer propulsion mechanism, a positioning block, a pressing propulsion mechanism, and a receiving propulsion mechanism. The positioning block is provided with a positioning space. The transfer range of the transfer propulsion mechanism covers the feeding device and the positioning space. When the battery is located in the positioning space, the positioning block fits against two adjacent side walls of the battery. The transfer propulsion mechanism and the pressing propulsion mechanism respectively cooperate with the positioning block to clamp the battery. The receiving propulsion mechanism receives the battery, and at least a part of the discharging device is located directly below the positioning space. Among them, the receiving propulsion mechanism can receive the battery and drop the battery into the discharging device. It is not necessary to use a driver to push the latter battery to move and cause the former battery to move to achieve the battery output operation, which can avoid the collision of the side walls of two batteries due to the push of the driver, thereby better protecting the battery.

[0019] Further, the transfer propulsion mechanism includes: a transfer block and a transfer driver. The transfer driver is connected to the transfer block to drive the transfer block to approach or move away from the positioning space in the horizontal direction. The moving range of the transfer block covers the feeding device and the positioning space. Among them, driving the transfer block to move by the transfer driver can not only achieve the transfer operation of the battery but also achieve the positioning operation of the battery, so that the transfer propulsion mechanism has both the functions of transfer and pressing at the same time.

[0020] Further, the pressing propulsion mechanism includes: a pressing block, a pressing driver, a baffle, a spring, and a push plate. The pressing driver is connected to both the pressing block and the push plate to drive the pressing block and the push plate to approach or move away from the positioning space in the horizontal direction. The two ends of the spring are respectively abutted against the baffle and the push plate. Among them, the spring is provided to play a buffering role to avoid damaging the battery due to the too fast moving speed of the pressing block.

[0021] Further, the receiving and advancing mechanism includes: a receiving block and a receiving driver, where the receiving driver is connected to the receiving block to drive the receiving block to approach or move away from directly below the positioning space in the horizontal direction. When the receiving block is directly below the positioning space, the receiving block is located in the discharging device. Among them, using the receiving driver to drive the receiving block can not only achieve the dropping of the battery but also realize the feeding operation of the battery in the discharging device, and there is no need to set other drivers in the discharging device, thus reducing the cost.

[0022] Further, the discharging device includes: a discharging track and a discharging stopper. The discharging track is provided with a step, and the step is located directly below the positioning space. The discharging stopper is arranged on the discharging track, and the discharging stopper is provided with an inclined surface for fitting the battery. Among them, since the discharging track is provided with a step, when the receiving block returns to directly below the positioning space, it can push the battery to fall backward, and then smoothly leave the step, avoiding the situation of battery blockage; the inclined surface of the discharging stopper exactly maintains the fallen battery in an inclined state.

[0023] After adopting the above technical solution, the beneficial effect is that: since the steel ball sealer of the present invention can block the output channel by using the sliding plate before sealing, even if the electrolyte overflows from the liquid injection port during the battery positioning process, the electrolyte can be maintained in the output channel and pushed back into the battery interior during the sealing process, thus avoiding the problem of pollution.

Detailed implementation manners

[0033] The technical solution of the present utility model will be further described below through embodiments:

[0034] The present utility model provides a steel ball sealing machine for a battery, as Figure 2 shown. The steel ball sealing machine includes: a feeding device 1, a transfer and positioning device 2, a sealing device 3, and a discharging device 4. The transfer range of the transfer and positioning device 2 covers the feeding device 1, the sealing device 3, and the discharging device 4. When the steel ball sealing machine works, first, the feeding device 1 is used to input the battery 100 from front to back, then the transfer and positioning device 2 is used to transfer the battery 100 to the sealing device 3 along the left and right directions, then the sealing device 3 is used to press the steel ball downward into the liquid outlet 101 of the battery 100, and finally the transfer and positioning device 2 is used to transfer the battery 100 downward to the discharging device 4, and the discharging device 4 is used to output the battery 100 backward.

[0035] Specifically, as Figure 3As shown in the figure, the feeding device 1 includes: a motor 11, a plurality of belt shafts 12, a belt 13, and a feeding stopper 14. The motor 11 is connected to one belt shaft 12. The belt 13 is wound around a plurality of belt shafts 12. The feeding stopper 14 is located on the belt, and the feeding stopper 14 is provided with a vertical surface for fitting the battery 100. When the feeding device 1 is working, the motor 11 drives one belt shaft 12 to rotate, thereby driving the belt 13 to move around a plurality of belt shafts 12. A plurality of batteries 100 are placed on the belt 13 in a row, and the feeding stopper 14 and the plurality of batteries 100 move along with the movement of the belt 13. The feeding stopper 14 fits the battery 100 at the frontmost position.

[0036] Although in this embodiment, the feeding device 1 realizes the battery 100 input operation by driving the belt 13 to move with the motor 11, in other embodiments, the feeding device 1 may also adopt other structures, such as setting a linear module, a push plate, and a feeding track, and using the linear module to drive the push plate to move from front to back to promote the battery 100 to move in the feeding track, so as to realize the battery 100 input operation, as long as it can realize the linear transmission action of the battery.

[0037] In this embodiment, there are two belt shafts 12, while in other embodiments, the number of belt shafts 12 can also be three or more.

[0038] Specifically, as Figure 4 shown, the transfer and positioning mechanism 2 includes: a transfer propulsion mechanism 21, a positioning block 22, a pressing propulsion mechanism 23, and a receiving propulsion mechanism 24. The positioning block 22 is provided with a positioning space 220. The transfer range of the transfer propulsion mechanism 21 covers the feeding device 1 and the positioning space 220. When the battery 100 is located in the positioning space 220, the positioning block 22 fits the two adjacent side walls of the battery 100. The transfer propulsion mechanism 21 and the pressing propulsion mechanism 23 cooperate with the positioning block 22 respectively to clamp the battery 100. The receiving propulsion mechanism 24 receives the battery 100, and at least a part of the discharging device 4 is located directly below the positioning space 220. When the transfer and positioning mechanism 2 is working, the transfer propulsion mechanism 21 can transfer the battery 100 to be sealed to the positioning space 220. At this time, the transfer propulsion mechanism 21 and the pressing propulsion mechanism 23 cooperate with the positioning block 22 respectively to clamp the battery 100, so as to realize the positioning of the battery 100 in the horizontal direction. The receiving propulsion mechanism 24 supports the lower surface of the battery 100 to cooperate with the sealing operation. When the sealing is completed, the receiving propulsion mechanism 24 no longer receives the battery 100, and the battery 100 falls to the discharging device 4.

[0039] In this embodiment, the positioning block 22 is L-shaped. When the battery 100 is located in the positioning space 220, the two inner surfaces of the positioning block 22 respectively fit the two adjacent side walls of the battery 100.

[0040] More specifically, the transfer propulsion mechanism 21 includes: a transfer block 211 and a transfer driver 212. The transfer driver 212 is connected to the transfer block 211 to drive the transfer block 211 to approach or move away from the positioning space 220 in the horizontal direction. The moving range of the transfer block 211 covers the feeding device 1 and the positioning space 220. When the transfer propulsion mechanism 21 works, the transfer driver 212 is used to drive the transfer block 211 to move, push the battery 100 on the feeding device 1 into the positioning space 220, and cooperate with the positioning block 22 to clamp the battery 100 in the left-right direction.

[0041] More specifically, the pressing propulsion mechanism 23 includes: a pressing block 231, a pressing driver 232, a baffle 233, a spring 234, and a push plate 235. The pressing driver 232 is connected to both the pressing block 231 and the push plate 235 to drive the pressing block 231 and the push plate 235 to approach or move away from the positioning space 220 in the horizontal direction. The two ends of the spring 234 are respectively abutted against the baffle 233 and the push plate 235. When the pressing propulsion mechanism 23 works, the pressing driver 232 can be used to drive the pressing block 231 to move towards the positioning space 220, and cooperate with the positioning block 22 to clamp the battery in the front-rear direction. At this time, the spring 234 is compressed under the combined action of the baffle 233 and the push plate 235.

[0042] In this embodiment, the pressing block 231, the baffle 233, and the push plate 235 are arranged in sequence from back to front, and the pressing block 231 is located at a position closer to the positioning space 220 than the baffle 233.

[0043] More specifically, the receiving propulsion mechanism 24 includes: a receiving block 241 and a receiving driver 242. The receiving driver 242 is connected to the receiving block 241 to drive the receiving block 241 to approach or move away from directly below the positioning space 220 in the horizontal direction. When the receiving block 241 is directly below the positioning space 220, the receiving block 241 is located in the discharging device 4. When the receiving propulsion mechanism 24 works, the receiving driver 242 can be used to drive the receiving block 241 to move directly below the positioning space 220, so as to support the lower surface of the battery 100; after the sealing is completed, the receiving driver 242 is used to drive the receiving block 241 to move away from directly below the positioning space 220, and the battery 100 drops into the discharging device 4. In addition, when the receiving block 241 returns to directly below the positioning space 220 again, it will push the battery 100 in the discharging device 4 to move, realizing the output operation of the battery 100.

[0044] Specifically, as Figure 5As shown, the sealing device 3 includes: a steel ball input mechanism 31, a transfer block 32, a sliding propulsion mechanism 33, a top ball propulsion mechanism 34, a vertical adjustment mechanism 35, a bracket 36, and a horizontal adjustment mechanism 37. The sliding propulsion mechanism 33 is inserted into the transfer block 32 to transfer the steel balls from a steel ball input position of the transfer block 32 to a steel ball output position. The steel ball input mechanism 31 is communicated with the transfer block 32 to transfer the steel balls to the steel ball input position. The top ball propulsion mechanism 34 is inserted into the transfer block 32 to press the steel balls from the steel ball output position into the liquid injection port 101 of the battery 100. Both the transfer block 32 and the sliding propulsion mechanism 33 are arranged on the vertical adjustment mechanism 35 to adjust the vertical position of the transfer block 32. Both the top ball propulsion mechanism 34 and the vertical adjustment mechanism 35 are arranged on the bracket 36, and the bracket 36 is arranged on the horizontal adjustment mechanism 37 to adjust the horizontal position of the transfer block 32. When the sealing device 3 is working, the battery 100 is located directly below the transfer block 32. First, the steel ball input mechanism 31 is used to transfer the steel balls to the steel ball input position, then the sliding propulsion mechanism 33 is used to transfer the steel balls from the steel ball input position to the steel ball output position, and then the top ball propulsion mechanism 34 is used to press the steel balls from the steel ball output position into the liquid outlet 101 of the battery 100. In addition, the three-dimensional position of the transfer block 32 can be adjusted by using the vertical adjustment mechanism 35 and the horizontal adjustment mechanism 37.

[0045] More specifically, as Figure 6 shown, the steel ball input mechanism 31 includes: an input pipe 311 and a containing box 312. The input pipe 311 is communicated with the containing box 312, and the input pipe 311 extends from the containing box 312 to the steel ball input position. When the steel ball input mechanism 31 is working, the containing box 312 is used to contain the steel balls, and the steel balls are transferred to the steel ball input position of the transfer block 32 through the input pipe 311. Among them, the inner diameter of the input pipe 311 is slightly larger than the diameter of the steel ball, that is, the input pipe 311 only inputs one steel ball each time.

[0046] In this embodiment, the side wall of the containing box 312 is also provided with an air blowing hole, and the air blowing hole is communicated with an air pump. Blowing air by using the air pump can prompt the steel balls in the containing box 312 to fall into the input pipe 311, reducing the possibility of blockage.

[0047] More specifically, the sliding propulsion mechanism 33 includes: a sliding plate 331 and a sliding driver 332. The sliding plate 331 is provided with a steel ball hole 3310. The sliding plate 331 is inserted into the transfer block 32, and the sliding driver 332 is connected to the sliding plate 331 to drive the steel ball hole 3310 to move between the steel ball input position and the steel ball output position. When the sliding propulsion mechanism 33 is working, the sliding driver 332 can be used to drive the sliding plate 331 to move, so that the steel ball hole 3310 moves between the steel ball input position and the steel ball output position, thereby realizing the transfer of the steel balls. Among them, the inner diameter of the steel ball hole 3310 is slightly larger than the diameter of the steel ball, that is, each steel ball hole 3310 just contains one steel ball.

[0048] More specifically, the top bead pushing mechanism 34 includes a thimble 341 and a top bead driver 342. The thimble 341 is inserted into the transfer block 32, and the top bead driver 342 is connected to the thimble 341 to drive the thimble 341 to push out the beads at the bead output position. When the top bead pushing mechanism 34 works, the top bead driver 342 can be used to drive the thimble 341 to move, so as to press the beads at the bead output position into the liquid injection port 101 of the battery 100.

[0049] More specifically, as Figure 7 shown, the transfer block 32 is provided with a convex column 320, a transfer channel 321, an output channel 322, a limiting channel 323 and a guiding channel 324. The convex column 320 protrudes downward from the lower surface of the transfer block 32. The transfer channel 321 is provided with the above-mentioned bead input position and bead output position. The limiting channel 323 is located directly above the bead input position. The upper port of the output channel 322 is located directly below the bead output position. The guiding channel 324 is located directly above the bead output position. The lower port of the output channel 322 is located on the lower surface of the convex column 320. The sliding plate 331 is inserted into the transfer channel 321, and when the bead hole 3310 is located at the bead input position, the sliding plate 331 blocks the output channel 322. The thimble 341 is inserted into the guiding channel 324, and the input pipe 311 is inserted into the limiting channel 323. When the transfer block 32 works, the sliding plate 331 moves in the transfer channel 321 to realize the transfer of the beads between the bead input position and the bead output position. The thimble 341 moves in the guiding channel 324 and the output channel 322 to press the beads at the bead output position into the liquid injection port 101 of the battery 100. Among them, the convex column 320 can avoid the ear 102 of the battery 100, so that the output channel 322 can reach directly above the liquid injection port 101 smoothly.

[0050] In this embodiment, the transfer channel 321 is horizontally arranged, the output channel 322 is vertically arranged, and the inner diameters of the transfer channel 321 and the output channel 322 are both slightly larger than the diameter of the bead, that is, the transfer channel 321 and the output channel 322 each output only one bead at a time.

[0051] More specifically, please continue to refer to Figure 6 shown, the vertical adjustment mechanism 35 includes a lifting block 351 and a lifting driver 352. The transfer block 32 and the sliding pushing mechanism 33 are both arranged on the lifting block 351. The lifting driver 352 is connected to the lifting block 351 to adjust the vertical position of the lifting block 351. When the vertical adjustment mechanism 35 works, the lifting driver 352 is used to drive the lifting block 351 to move, so as to adjust the vertical position of the transfer block 32.

[0052] More specifically, please continue to refer to Figure 5As shown, the horizontal adjustment mechanism 37 includes: a lower adjustment block 371, an intermediate block 372, an upper adjustment block 373, a first screw rod 374 and a second screw rod 375. The lower surface and the upper surface of the intermediate block 372 are respectively provided with a lower guide groove and an upper guide groove, and the lower guide groove and the upper guide groove are perpendicular to each other. The lower adjustment block 371 and the upper adjustment block 373 are respectively movably arranged in the lower guide groove and the upper guide groove, the bracket 36 is fixed to the upper adjustment block 373, the intermediate block 372 is provided with a first nut, and the upper adjustment block 373 is provided with a second nut. The first screw rod 374 is meshed with the first nut and forms a rotation connection with the lower adjustment block 371, and the second screw rod 375 is meshed with the second nut and forms a rotation connection with the intermediate block 372. When the horizontal adjustment mechanism 37 is working, rotating the first screw 374 can cause the middle block 372 to move relative to the lower adjustment block 371, and rotating the second screw 375 can cause the upper adjustment block 373 to move relative to the middle block 372, thereby adjusting the horizontal position of the bracket 36 and further adjusting the horizontal position of the transfer block 32.

[0053] Specifically, if Figure 8 As shown, the discharge device 4 includes: a discharge track 41 and a discharge block 42. The discharge track 41 is provided with a step 410, and the step 410 is located directly below the positioning space 220.
