[0002] In the battery production process, there are many steps or logistics lines that require positioning or resetting the batteries. However, existing positioning mechanisms can only position square batteries in the horizontal direction, and the positioning effect of square batteries in the vertical direction is poor.

The stop is fixed to the movable end of the drive assembly and can enter and exit the conveying channel of the battery conveying line in a second direction, tilted backward relative to the front side of the battery, under the drive of the drive assembly. This square battery positioning mechanism provides a way to avoid wear on the battery during resetting after positioning. The positioning mechanism in the aforementioned patent can only position square batteries horizontally; its positioning effect in the vertical direction is poor. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0024] Please see Figure 1-4A square battery positioning device according to an embodiment of the present invention includes a positioning base 1, a pressure block 7, two positioning rods 2, two first pushers for moving the two positioning rods 2 closer to or further away in the horizontal direction, a second pusher for moving the pressure block 7 closer to or further away from the positioning base 1 in the vertical direction, a controller 22 for controlling the first pushers and the second pushers, and a battery 23 for supplying power to the first pushers, the second pushers, and the controller 22. When the square battery is placed in a first position on the positioning base 1, the two first pushers move the two positioning rods 2 closer to the square battery, so that the two positioning rods 2 abut against the left and right sides of the square battery respectively. The second pusher moves the pressure block 7 closer to the square battery, so that the pressure block 7 abuts against the top surface of the square battery.

[0025] Here, two positioning rods 2 are respectively set on both sides of the first position of the positioning base 1. The square battery is placed on the first position of the positioning base 1, with the left and right sides of the square battery facing each other. One positioning rod 2 is located on one side of the left side of the square battery, and the other positioning rod 2 is located on one side of the right side of the square battery. The two first pushing members drive the two positioning rods 2 respectively, and the two positioning rods 2 move towards the square battery. After the two positioning rods 2 have moved a certain distance, the two positioning rods 2 abut against the left and right sides of the square battery respectively, that is, one positioning rod 2 abuts against the left side of the square battery and the other positioning rod 2 abuts against the right side of the square battery. The second pushing member drives the pressing block 7, and the pressing block 7 moves towards the square battery. After the pressing block 7 has moved a certain distance, the pressing block 7 abuts against the top surface of the square battery. Through the combined action of the two positioning rods 2 and the pressing block 7, the square battery is positioned well.

[0026] There can be two pressure blocks 7, and two second pushers are respectively set to correspond to the two pressure blocks 7. The two positioning rods 2, the two first pushers, the two pressure blocks 7, and the two second pushers are all symmetrically arranged about the center of the top of the positioning seat 1.

[0027] Specifically, the two second pushing members drive the two pressing blocks 7 to move towards the square battery, and the two pressing blocks 7 move towards the top surface of the square battery, so that the two pressing blocks 7 abut against the top surface of the square battery. The two pressing blocks 7 are symmetrically arranged about the center of the top of the positioning seat 1, so one pressing block 7 abuts against the left end of the top surface of the square battery and the other pressing block 7 abuts against the right end of the top surface of the square battery. The two second pushing members can be connected to the two positioning rods 2 respectively.

[0028] The first pushing component may include a drive wheel 13, an adjusting shaft 12, a drive motor 20, and a first spring 21. The drive wheel 13 is disposed above the positioning seat 1, and the side of the drive wheel 13 abuts against the positioning rod 2. One end of the adjusting shaft 12 is eccentrically connected to the drive wheel 13, and the other end is connected to the output end of the drive motor 20. The two ends of the first spring 21 are respectively connected to the positioning seat 1 and the positioning rod 2. The drive motor 20 is controlled by the controller 22. The drive motor 20 is used to drive the adjusting shaft 12, so that the adjusting shaft 12 drives the drive wheel 13 to rotate.

[0029] Specifically, the positioning seat 1 is horizontally positioned, the drive wheel 13 is parallel to the top surface of the positioning seat 1, the positioning rod 2 can be vertically positioned, and the adjusting shaft 12 can be vertically positioned. One end of the adjusting shaft 12 is eccentrically connected to the drive wheel 13, and the other end is connected to the output end of the drive motor 20. The drive motor 20 drives the adjusting shaft 12, and the adjusting shaft 12 drives the drive wheel 13 to rotate. During the process from the first part of the drive wheel 13 near the adjusting shaft 12 abutting the positioning rod 2 to the second part of the drive wheel 13 away from the adjusting shaft 12 abutting the positioning rod 2, the thrust applied by the drive wheel 13 to the positioning rod 2 gradually increases, thereby pushing the positioning rod 2 to abut against the square battery. The first driving wheel 13 pushes the first positioning rod 2 to abut against the left side of the square battery, and the second driving wheel 13 pushes the second positioning rod 2 to abut against the right side of the square battery.

[0030] The first pushing component may further include an air pump 19, an air intake ring 17, a guide pipe 18, a second spring 16, a locking block 15, a first mounting groove located at a first eccentric position within the drive wheel 13, a first insertion groove located within the drive wheel 13 and communicating with the first mounting groove, a second mounting groove located inside the adjusting shaft 12, a first insertion through hole located at the side end of the adjusting shaft 12 and communicating with the second mounting groove, and a guide groove 14 located inside the adjusting shaft 12 and communicating with the second mounting groove. The air pump 19 is controlled by a controller 22. The length of one end of the locking block 15 is greater than the length of the first insertion through hole, and the length of the other end is less than the length of the first insertion through hole. One end of the second spring 16 is connected to the side wall of the first mounting groove, and the other end is connected to... One end of the block 15 is connected to the guide pipe 18; both ends of the guide pipe 18 are connected to the air pump 19 and the air intake ring 17 respectively. The air intake ring 17 is rotatably connected to the outer circumference of the adjusting shaft 12 and is connected to the guide groove 14. The air pump 19 delivers gas to the first mounting groove through the guide pipe 18, the air intake ring 17 and the guide groove 14 in sequence, so that the gas pushes the block 15 to move towards the drive wheel 13 until the other end of the block 15 passes through the first insertion hole and is inserted into the first insertion groove. The air pump 19 extracts the gas in the first mounting groove through the guide pipe 18, the air intake ring 17 and the guide groove 14 in sequence, so that the second spring 16 pulls the block 15 to move away from the drive wheel 13 until the other end of the block 15 disengages from the first insertion groove.

[0031] Specifically, the air pump 19 can be a miniature air pump. The locking block 15 may include a first insertion part and a first stop part connected to the first insertion part. The length of the first insertion part is less than the length of the first insertion through hole, so that the first insertion part can pass through the first insertion through hole. The length of the first stop part is greater than the length of the first insertion through hole, so that the first stop part cannot pass through the first insertion through hole. The air pump 19 delivers gas to the first mounting groove in sequence through the guide pipe 18, the air inlet ring 17, and the guide groove 14. The gas pushes the locking block 15 to move towards the drive wheel 13, that is, the gas pushes the first insertion part of the locking block 15 to move towards the first insertion groove. At this time, the locking block 15 moves against the tension of the second spring 16 until the first insertion part of the locking block 15 is engaged. The first part of the positioning rod 2 is inserted into the first insertion slot and abuts against the side wall of the first insertion slot and / or the first stop part of the locking block 15 abuts against the side wall of the first mounting slot near the first insertion through hole. The second spring 16 is in a stretched state, realizing the fixed connection between the positioning rod 2 and the drive wheel 13. The air pump 19 sequentially extracts the gas in the first mounting slot through the guide pipe 18, the air inlet ring 17, and the guide groove 14. The second spring 16 pulls the locking block 15 to move away from the drive wheel 13, that is, the second spring 16 pulls the first insertion part of the locking block 15 to move away from the first insertion slot until the first insertion part of the locking block 15 disengages from the first insertion slot, realizing the separation of the positioning rod 2 and the drive wheel 13.

[0032] Specifically, it also includes two first receiving slots, two second receiving slots, two third receiving slots, and two fourth receiving slots set in the positioning seat 1. The two second receiving slots correspond one-to-one with the two first receiving slots, the two third receiving slots correspond one-to-one with the two second receiving slots, and the two fourth receiving slots correspond one-to-one with the two second receiving slots. Each second receiving slot is connected to its corresponding first receiving slot, each third receiving slot is connected to its corresponding second receiving slot, and each fourth receiving slot is connected to its corresponding first receiving slot. The top of the positioning rod 2 is inserted into the first... The first receiving groove is inserted into the bottom of the groove. The drive motor 20 is vertically set in the fourth receiving groove. The output end of the drive motor 20 is connected to the bottom end of the positioning rod 2. The air intake ring 17 is set in the second receiving groove. The air pump 19 and the guide pipe 18 are both vertically set in the third receiving groove. The bottom end of the guide pipe 18 is connected to the air pump 19 and the top end is connected to the air intake ring 17. The air intake ring 17 is rotatably connected to the outer circumference of the adjusting shaft 12. The air intake ring 17 is provided with a first air guide hole. The part of the adjusting shaft 12 connected to the air intake ring 17 is provided with a second air guide hole that communicates with the first air guide hole. The second air guide hole communicates with the guide groove 14. The air intake ring 17 will not rotate when the positioning rod 2 rotates.

[0033] The first insertion slot can be two symmetrically arranged, the locking block 15 is two corresponding to the two first insertion slots, and the second spring 16 is multiple corresponding to the two locking blocks 15.

[0034] Specifically, if there are two symmetrically arranged second springs 16 corresponding to one locking block 15, then there are two first insertion slots for the second springs 16 in one first pushing member, two locking blocks 15, and four second springs 16.

[0035] The second pushing component may include a sliding seat 5, a first lifting structure connected to the positioning rod 2 for moving the sliding seat 5 up and down in the vertical direction, and a first rotating structure for rotating the pressure block 7. The first rotating structure is connected to the sliding seat 5 and the pressure block 7 respectively. The first lifting structure and the first rotating structure are both controlled by the controller 22. The first lifting structure moves the sliding seat 5 upward to a first preset height, the first rotating structure moves the pressure block 7 to rotate parallel to the top surface of the square battery, and the first lifting structure moves the sliding seat 5 downward to a second preset height, so that the pressure block 7 abuts against the top surface of the square battery.

[0036] Specifically, when it is necessary to position the top surface of the square battery, the first lifting structure first moves the sliding seat 5 upward to the first preset height, then the first rotating structure moves the pressure block 7 to be parallel to the top surface of the square battery, and then the first lifting structure moves the sliding seat 5 downward to the second preset height, so that the pressure block 7 abuts against the top surface of the square battery, thus realizing the positioning of the top surface of the square battery by the pressure block 7; when the positioning of the top surface of the square battery is completed, the first lifting structure first moves the sliding seat 5 upward to the first preset height, and then the first rotating structure moves the pressure block 7 to be perpendicular to the top surface of the square battery.

[0037] The first lifting structure may include an electric slide rail 3 connected to the positioning rod 2, a slide table 4 mounted on the electric slide rail 3, a sliding seat 5 connected to the slide table 4, and the electric slide rail 3 used to drive the slide table 4 to move up and down in the vertical direction.

[0038] Specifically, the electric slide rail 3 is controlled by the controller 22. The electric slide rail 3 drives the slide table 4 to move up and down in the vertical direction, which in turn drives the slide seat 5 to move up and down in the vertical direction.

[0039] The first rotating structure may include a rotating shaft 6, a traction rope 9, a winding motor 11 connected to a sliding seat 5, a winding shaft 10 connected to the output end of the winding motor 11, and a spiral spring 8 disposed inside the pressure block 7. One end of the rotating shaft 6 is connected to the sliding seat 5, and the other end is rotatably connected to the pressure block 7. One end of the traction rope 9 is wound around the winding shaft 10, and the other end is connected to the pressure block 7. The winding motor 11 drives the winding shaft 10 to rotate along a first preset direction to wind up the traction rope 9, so that the traction rope 9 tightens the pressure block 7. The winding motor 11 drives the winding shaft 10 to rotate along a second preset direction to unwind the traction rope 9. The spiral spring 8 drives the pressure block 7 to rotate along a third preset direction, so that the pressure block 7 rotates to be parallel to the top surface of the square battery.

[0040] Specifically, the first preset direction can be clockwise, the second preset direction can be counterclockwise, and the third preset direction can be counterclockwise. When the winding motor 11 drives the winding shaft 10 to rotate along the first preset direction, the winding shaft 10 winds up the traction rope 9, causing the traction rope 9 to tighten the pressure block 7. At this time, the spiral spring 8 cannot drive the pressure block 7. When the winding motor 11 drives the winding shaft 10 to rotate along the second preset direction, the winding shaft 10 unwinds the traction rope 9, causing a portion of the traction rope 9 to detach from the winding shaft 10. The traction rope 9 then releases the pressure block 7. At this time, the spiral spring 8 can drive the pressure block 7 to rotate along the third preset direction, allowing the pressure block 7 to rotate to a position parallel to the top surface of the square battery.

[0041] Specifically, positioning rods 2 are slidably connected to both sides of the top center of positioning seat 1. An electric slide rail 3 is fixedly connected inside the positioning rod 2. A slide table 4 is installed on the outer wall of the electric slide rail 3 and inside the positioning rod 2. A sliding seat 5 is fixedly connected to the outer wall of the slide table 4 on the side away from the electric slide rail 3. A rotating shaft 6 is fixedly connected inside the sliding seat 5. A pressure block 7 is rotatably connected to the outer wall of the rotating shaft 6 and inside the sliding seat 5. A spiral spring 8 is fixedly connected inside the pressure block 7. A traction rope 9 is fixedly connected to the outer wall of the pressure block 7. A winding shaft 10 is fixedly connected to the outer wall of the traction rope 9 at the end away from the pressure block 7. A winding motor 11 is fixedly connected to the top of the winding shaft 10. The winding motor 11 is fixedly connected to the sliding seat 5, and the spiral spring 8 is fixedly connected to the rotating shaft 6. The sliding seat 5, the slide table 4, and the pressure block 7 are all slidably connected to the positioning rod 2.

[0042] Specifically, an adjusting shaft 12 is rotatably connected inside the positioning seat 1 near the positioning rod 2. A drive wheel 13 is slidably connected to the outer wall of the adjusting shaft 12. A guide groove 14 is formed inside the adjusting shaft 12. A locking block 15 is slidably connected inside the guide groove 14 and inside the drive wheel 13. A second spring 16 is fixedly connected to the outer wall of the locking block 15 and inside the guide groove 14. An air intake ring 17 is rotatably connected to the outer wall of the adjusting shaft 12 and below the drive wheel 13. A guide pipe 18 is fixedly connected inside the air intake ring 17. An air pump 19 is fixedly connected to the bottom end of the guide pipe 18. The bottom end of the adjusting shaft 12 is fixedly connected to the drive motor 20. The outer wall of the positioning rod 2 and the inside of the positioning seat 1 are fixedly connected to the first spring 21. The connection between the locking block 15 and the drive wheel 13 is a sliding connection. The first spring 21, the air intake ring 17, the air pump 19, the drive motor 20 and the positioning seat 1 are all fixedly connected. The front of the positioning seat 1 is fixedly connected to the controller 22. The bottom of the positioning seat 1 is equipped with a storage battery 23. The storage battery 23, the drive motor 20, the air pump 19, the electric slide rail 3 and the winding motor 11 are all electrically connected to the controller 22.

[0043] As a square battery positioning device in this embodiment, it may also include two first sliding grooves 24 disposed on the top of the positioning base 1, a plurality of third mounting grooves disposed on the positioning base 1 and respectively communicating with the corresponding first sliding grooves 24, the bottoms of the two positioning rods 2 respectively inserted into the two first sliding grooves 24, one end of the first spring 21 of a first pusher is connected to the part of the positioning rod 2 inserted into the first sliding groove 24, and the other end extends into the third mounting groove and is connected to the side wall of the third mounting groove.

[0044] Specifically, there can be two first springs 21 in a first pusher, and there are two third mounting slots connected to a first slide groove 24, with one first spring 21 installed in one third mounting slot.

[0045] As a square battery positioning device in this embodiment, it may also include a fourth mounting groove disposed in the positioning rod 2, a first connecting through hole disposed on one side of the positioning rod 2 away from the drive wheel 13, the first connecting through hole communicating with the fourth mounting groove, an electric slide rail 3 connected to the bottom wall and / or top wall of the fourth mounting groove, a slide table 4 disposed in the fourth mounting groove, and one end of the sliding seat 5 passing through the first connecting through hole and connected to the slide table 4.

[0046] Specifically, the positioning seat 1 is installed on the square battery conveyor line. The controller 22 starts the air pump 19. The air pump 19 draws air out of the guide groove 14 through the guide pipe 18 and the air inlet ring 17. The second spring 16 drives the locking block 15 to move inward. The inward-moving locking block 15 disengages from the drive wheel 13 and no longer locks the drive wheel 13. The appropriately sized drive wheel 13 is then placed back on the adjusting shaft 12. The air pump 19 sends air into the guide groove 14 through the guide pipe 18 and the air inlet ring 17. The air entering the guide groove 14 pushes the locking block 15 outward. The outward-moving locking block 15 re-inserts into the new drive wheel 13 and locks the new drive wheel 13 again. When the conveyor line conveys square batteries, the controller 22 starts the drive motor 20. The drive motor 20 drives the drive wheel 13 to rotate through the adjusting shaft 12. The rotating drive wheel 13 pushes the positioning rod 2 outward, causing it to approach and press against the square battery, thus positioning the square battery horizontally. Simultaneously, the controller 22 activates the electric slide rail 3, which, through the slide table 4, drives the sliding seat 5 upward. The upward-moving sliding seat 5 moves the pressure block 7 above the square battery. The controller 22 then activates the winding motor 11, which drives the winding shaft 10 to rotate. The rotating winding shaft 10 releases the traction rope 9, which no longer pulls the pressure block 7. The spiral spring 8 then drives the pressure block 7 to rotate outward until it reaches a horizontal position. The electric slide rail 3, through the slide table 4, drives the sliding seat 5 downward, causing the pressure block 7 to descend and press against the square battery, thus positioning the square battery vertically. This provides a better positioning of the square battery.

[0047] Specifically, the air pump 19 is started by the controller 22. The air pump 19 draws air out of the guide groove 14 through the guide pipe 18 and the air intake ring 17. The second spring 16 drives the locking block 15 to move inward. The locking block 15 moves out of the drive wheel 13 and no longer locks the drive wheel 13. The drive wheel 13 of the appropriate size is placed back on the adjusting shaft 12. The air pump 19 sends air into the guide groove 14 through the guide pipe 18 and the air intake ring 17. The air entering the guide groove 14 pushes the locking block 15 to move outward. The outward-moving locking block 15 will re-insert into the new drive wheel 13 and lock the new drive wheel 13 again. This makes it easy to replace drive wheels 13 of different sizes and can position square batteries of different sizes.
