Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to an iron-removing magnetic rod device and coating equipment. Background Art

[0002] Battery electrodes are an important component of batteries. During the production process, such as the coating process, impurities such as iron filings are usually stuck to the surface of the electrode. If the iron filings are not removed in time, the performance and stability of the battery will be seriously affected.

[0003] Currently, a magnetic rod device is usually installed in the coating equipment to absorb the iron filings on the surface of the pole piece and remove the iron filings on the surface of the pole piece. The magnetic rod device generally includes a magnetic rod mechanism, and two mounting brackets are respectively provided at both ends of the magnetic rod mechanism. The two mounting brackets are respectively installed on the adjacent side of the two side plates by screws. In actual application, the pole piece passes over the magnetic rod mechanism, and the magnetic rod mechanism absorbs the iron filings on the surface of the pole piece. When there are a large amount of iron filings on the magnetic rod mechanism, the iron filings on the magnetic rod mechanism need to be cleaned. The specific operation is to first stop the machine, then remove the two mounting brackets and the magnetic rod mechanism from the two side plates, and then clean the iron filings on the magnetic rod mechanism. The need to stop the machine increases the production time of the pole piece, reduces production efficiency, and increases production costs. Utility Model Content

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0028] Please refer to Figures 1 to 4 An embodiment of the present invention provides a magnetic rod device for removing iron, comprising a base 10 , two magnetic rod mechanisms 20 and a driving mechanism 30 .

[0029] The base 10 is arranged between the first side plate and the second side plate. The driving mechanism 30 is connected to one end of the base 10 and is used to drive the base 10 to rotate.

[0030] In this embodiment, a first rotating shaft 11 and a second rotating shaft 12 are respectively provided at one end and the other end of the base 10. The first rotating shaft 11 and the second rotating shaft 12 are respectively used to be set on the side close to the first side plate and the second side plate. Specifically, a through hole is respectively provided on the side of the first side plate close to the second side plate and the side of the second side plate close to the first side plate. The first rotating shaft 11 is used to pass through the through hole of the first side plate. The outer periphery of the first rotating shaft 11 is provided with a first bearing. The first bearing is used to be provided in the through hole of the first side plate to provide rotational support for the first rotating shaft 11. The end of the second rotating shaft 12 away from the base 10 is used to be rotatably provided in the through hole of the second side plate. The outer periphery of the end of the second rotating shaft 12 away from the base 10 is provided with a second bearing. The second bearing is used to be provided in the through hole of the second side plate to provide rotational support for the second rotating shaft 12.

[0031] The drive mechanism 30 includes a drive member 31 mounted on an L-shaped base 311. The base 311 is positioned on a side of the first side panel away from the second side panel to provide mounting support for the drive member 31. The end of the output shaft of the drive member 31 is connected to the end of the first rotating shaft 11 away from the base 10 via a universal joint 312. The drive member 31 is used to rotate the first rotating shaft 11, thereby driving the base 10 and the second rotating shaft 12 to rotate.

[0032] The driving member 31 is preferably a rotary cylinder. It is understandable that the driving member 31 can also be a motor or the like.

[0033] Two magnetic rod mechanisms 20 are removably mounted at the top and bottom ends of the base 10, symmetrically about the longitudinal centerline of the base 10. Rotation of the base 10 drives the two magnetic rod mechanisms 20 to rotate, swapping their positions. The magnetic rod mechanisms 20 are used to attract iron filings from the pole piece surface.

[0034] Specific, combined Figures 5 to 8 As shown, two support members 13 are provided at the top and bottom ends of the base 10, respectively. The two support members 13 correspond to the two magnetic bar mechanisms 20 and are symmetrical about the longitudinal centerline of the base 10. The longitudinal direction of the support members 13 is the same as that of the base 10. The support members 13 are provided with through slots 131 extending through both ends. An opening 132 is provided on the side of the support member 13 away from the base 10, communicating with the through slot 131. The width of the opening 132 is smaller than that of the through slot 131.

[0035] In this embodiment, Figure 6 As shown, the support member 13 includes a base plate 13a, two vertical plates 13b, and two horizontal plates 13c. The base plates 13a of the two support members 13 are disposed at the top and bottom ends of the base 10. Two recesses are provided on the side of the base plate 13a away from the base 10. The two recesses are symmetrical about the centerline of the length of the base plate 13a and extend to either side of the length of the base plate 13a. The two vertical plates 13b are disposed at the bottom of the two recesses and are positioned opposite each other. Portions of the two vertical plates 13b protrude from the side of the base plate 13a away from the base 10, forming the aforementioned through-slot 131 between the two vertical plates 13b. The two horizontal plates 13c are disposed on the side of the two vertical plates 13b away from the base 13a and are positioned opposite each other. The width of the horizontal plate 13c is greater than that of the vertical plates 13b, and the aforementioned opening 132 is formed between the two horizontal plates 13c.

[0036] The bottom plate 13a, the two vertical plates 13b and the two horizontal plates 13c may be integrally formed or separately formed.

[0037] The magnetic bar mechanism 20 includes a guide rail 21, a mounting seat 22, a magnetic bar 23, and a protective cover 24. The length directions of the guide rail 21, the mounting seat 22, the magnetic bar 23, and the protective cover 24 are all the same as the length direction of the support member 13. The guide rail 21 slides in engagement with the through slot 131 of the corresponding support member 13. The mounting seat 22 is disposed on the side of the guide rail 21 away from the base 10, and a portion of the mounting seat 22 extends from the opening 132 of the corresponding support member 13. The height of the portion of the mounting seat 22 extending from the opening 132 of the corresponding support member 13 can be set according to actual conditions. The magnetic bar 23 is disposed on the side of the mounting seat 22 away from the guide rail 21. The protective cover 24 is U-shaped and can be removably mounted on the outside of the magnetic bar 23. The protective cover 24 is preferably a sheet metal part. The protective cover 24 protects the magnetic bar 23 from damage. In addition, the protective cover 24 is provided to facilitate the cleaning of iron filings. Specifically, when the pole piece passes over the protective cover 24, the iron filings on the surface of the pole piece can be adsorbed on the protective cover 24 under the magnetic effect of the magnetic bar 23. After the protective cover 24 is removed from the magnetic bar 23, the protective cover 24 is not magnetic and thus no longer adsorbs the iron filings. At this time, the iron filings on the protective cover 24 can be directly shaken off, thereby achieving the cleaning of the iron filings, which is simple and quick.

[0038] A handle 211 is provided on the side of the guide rail 21 away from the base 10. The handle 211 partially extends from the opening 132 of the corresponding support member 13, and the handle 211 is adjacent to the end of the guide rail 21 away from the drive mechanism 30. The handle 211 is convenient for grasping, thereby facilitating the removal of the guide rail 21 from the through slot 131 of the corresponding support member 13 or the insertion of the guide rail 21 into the through slot 131 of the corresponding support member 13, thereby facilitating the assembly and disassembly of the magnetic bar mechanism 20.

[0039] A screw hole 212 is provided on one side of the guide rail 21 away from the base 10. Figure 8 As shown, the screw hole 212 is located between the handle 211 and the mounting base 22. The knob plunger 213 is threadedly installed in the screw hole 212. The bottom of the through groove 131 is provided with a through hole 1311 corresponding to the screw hole 212. The tail end of the knob plunger 213 extends from the screw hole 212 and is inserted into the through hole 1311 of the corresponding through groove 131. The knob plunger 213 is an existing structure, such as Figure 8As shown, the knob plunger 213 mainly includes a plunger body 2131, a pin 2132, a locking nut 2133, a spring and a knob 2134. The outer wall of the plunger body 2131 is provided with an external thread, and the plunger body 2131 is threadedly mounted in the screw hole 212 through its external thread. The top end of the plunger body 2131 extends from the opening 132 of the corresponding support member 13. The bottom end of the knob 2134 abuts against the top end of the plunger body 2131. The pin 2132 is located in the plunger body 2131, and the head of the pin 2132 extends from the top end of the plunger body 2131 and is connected to the bottom end of the knob 2134. The tail end of the pin 2132 protrudes from the bottom end of the plunger body 2131 and extends from the screw hole 212, and is inserted into the through hole 1311 of the corresponding through groove 131. The locking nut 2133 is threadedly engaged with the plunger body 2131 and abuts against the side of the guide rail 21 away from the base 10 to lock the plunger body 2131 and the guide rail 21 together. A spring is provided in the plunger body 2131 and sleeved on the outer circumference of the pin 2132. One end of the spring is connected to the outer wall of the pin 2132, and the other end of the spring is connected to the top inside the plunger body 2131. The knob plunger 213 is provided to fix the guide rail 21 and the corresponding support member 13 together, thereby preventing the guide rail 21 from sliding in the corresponding through slot 131, and further preventing the magnetic bar mechanism 20 from moving along the length direction of the base 10. In actual application, by pulling the knob 2134 in the direction away from the plunger body 2131, the pin 2132 can be retracted into the plunger body 2131. At this time, the pin 2132 is separated from the corresponding through hole 1311 of the through groove 131 and the spring is compressed. When the knob 2134 is released, the pin 2132 can be driven back to its original position under the reset drive of the spring. At this time, the tail end of the pin 2132 is reinserted into the through hole 1311 of the corresponding through groove 131.

[0040] A stopper 133 is provided at the bottom of the through slot 131. The stopper 133 partially protrudes from the end of the support member 13 near the drive mechanism 30. The end of the guide rail 21 near the drive mechanism 30 abuts against the stopper 133. The stopper 133 serves to limit the corresponding guide rail 21.

[0041] When it is necessary to remove the two magnetic rod mechanisms 20 from the top and bottom ends of the base 10, for example, taking the magnetic rod mechanism 20 installed at the top end of the base 10 as an example, first pull the knob 2134 of the knob plunger 213 in the direction away from the guide rail 21, thereby driving the pin 2132 of the knob plunger 213 to retract into the plunger body 2131 of the knob plunger 213. At this time, the pin 2132 is separated from the through hole 1311 of the corresponding through groove 131, the spring is compressed, and then it is pulled away from the driving mechanism 30. By pulling the handle 211, the guide rail 21 can be driven to slide in the corresponding through slot 131 in the direction away from the driving mechanism 30, and then the mounting seat 22, the magnetic bar 23 and the protective cover 24 can be driven to move in the direction away from the driving mechanism 30 until the guide rail 21 moves out of the corresponding through slot 131, and then the knob 2134 of the knob plunger 213 is released. Driven by the return of the spring, the pin 2132 can be driven to return to its original position, and the magnetic bar mechanism 20 is removed from the top of the base 10. When the magnetic rod mechanism 20 needs to be installed on the top of the base 10, the end of the guide rail 21 close to the driving mechanism 30 is first inserted into the corresponding through slot 131, and then the knob 2134 of the knob plunger 213 is pulled in the direction away from the guide rail 21, thereby driving the pin 2132 of the knob plunger 213 to retract into the plunger body 2131 of the knob plunger 213, and at the same time, the handle 211 is pushed in the direction close to the driving mechanism 30, thereby driving the guide rail 21 in the corresponding through slot 131 toward the driving mechanism 30. 0, thereby driving the mounting base 22, the magnetic rod 23 and the protective cover 24 to move toward the driving mechanism 30 until the end of the guide rail 21 close to the driving mechanism 30 abuts against the limit block 133, and then releasing the knob 2134 of the knob plunger 213. Driven by the reset of the spring, the pin 2132 is driven to return to its original position. At this time, the tail end of the pin 2132 is re-inserted into the through hole 1311 of the corresponding through slot 131, and the magnetic rod mechanism 30 is thus installed on the top of the base 10.

[0042] A groove 214 is provided on the side of the guide rail 21 away from the base 10, and the mounting seat 22, screw hole 212 and handle 211 are respectively arranged at the bottom of the groove 214, and the locking nut 2133 of the knob plunger 213 is against the bottom of the groove 214. This method can reduce the overall height of the demagnetizing rod device.

[0043] The bottom of the through slot 131 is provided with a first chamfer 1312 at one end away from the driving mechanism 30 (i.e., the side of the bottom plate 13a away from the base 10, which is the end away from the driving mechanism 30). The inner walls on both sides of the opening 132 are provided with two second chamfers 1321 at one end away from the driving mechanism 30 (i.e., the side of the two horizontal plates 13c close to each other, which is the end away from the driving mechanism 30). Figure 6The first chamfer 1312 and the second chamfer 1321 are provided to facilitate inserting the end of the guide rail 21 close to the driving mechanism 30 into the corresponding through slot 131 during the installation of the magnetic bar mechanism 20 .

[0044] The protective cover 24 is detachably mounted on the outside of the magnetic rod 23. Specifically, Figure 8 As shown, a first hole 231 is provided on one side of the magnetic bar 23, and a first avoidance hole 241 corresponding to the first hole 231 is provided on one side of the protective cover 24. The first fastener 25 is installed in the first hole 231, the head of the first fastener 25 passes through the first avoidance hole 241 and is provided with a first fastener cap 251 by means of a threaded connection, and the first fastener cap 251 abuts against one side of the protective cover 24. A second hole is provided on the other side of the magnetic bar 23, and a second avoidance hole 242 corresponding to the second hole is provided on the other side of the protective cover 24. The second fastener 26 is installed in the second hole, the head of the second fastener 26 passes through the second avoidance hole 242 and is provided with a second fastener cap 261 by means of a threaded connection, and the second fastener cap 261 abuts against the other side of the protective cover 24. The first hole 231 and the second hole are both threaded holes, and the first fastener 25 and the second fastener 26 are both screws.

[0045] In this embodiment, the first avoidance hole 241 and the second avoidance hole 242 are both L-shaped, and the first avoidance hole 241 and the second avoidance hole 242 both include a vertical through hole 241a and a horizontal through hole 241b. Figure 8 As shown, one end of the vertical through hole 241a extends to the end of the protective cover 24 near the corresponding support member 13, and the other end of the vertical through hole 241a is connected to one end of the transverse through hole 241b. The other ends of the transverse through holes 241b both extend in a direction away from the drive mechanism 30. The head of the first fastener 25 passes through the other end of the transverse through hole 241b of the first avoidance hole 241, and the head of the second fastener 26 passes through the other end of the transverse through hole 241b of the second avoidance hole 242. The cross-sectional shape of the other end of the transverse through hole 241b of the first avoidance hole 241 matches the cross-sectional shape of the first fastener 25, and the cross-sectional shape of the other end of the transverse through hole 241b of the second avoidance hole 242 matches the cross-sectional shape of the second fastener 26. This structure does not require the first fastener 25 or the second fastener 26 to be disassembled when disassembling the protective cover 24, making disassembly and assembly convenient.

[0046] When the protective cover 24 needs to be removed from the magnetic rod 23, first loosen the first fastener cap 251 and the second fastener cap 261 to separate the first fastener cap 251 and the second fastener cap 261 from the protective cover 24, and then push the protective cover 24 in the direction away from the driving mechanism 30, so that the first fastener 25 is located in one end of the transverse through hole 241b of the first avoidance hole 241, and the second fastener 26 is located in one end of the transverse through hole 241b of the second avoidance hole 242. At this time, the vertical through hole 241a of the first avoidance hole 241 and the vertical through hole 241a of the second avoidance hole 242 respectively avoid the first fastener 25 and the second fastener 26, and then pull the protective cover 24 upward to remove the protective cover 24 from the magnetic rod 23. When the protective cover 24 needs to be installed on the magnetic rod 23, the protective cover 24 is first placed above the magnetic rod 23 and the vertical through hole 241a of the first avoidance hole 241 and the vertical through hole 241b of the second avoidance hole 242 are aligned with the first fastener 25 and the second fastener 26 respectively, and then the protective cover 24 is moved downward. In this way, the protective cover 24 is sleeved on the outside of the magnetic rod 23. At this time, the first fastener 25 is located in one end of the horizontal through hole 241b of the first avoidance hole 241, and the second fastener 26 is located in the horizontal through hole 241b of the second avoidance hole 242. One end of the through hole 241b, and then pull the protective cover 24 toward the direction close to the driving mechanism 30 until the first fastener 25 is located in the other end of the transverse through hole 241b of the first avoidance hole 241 and the second fastener 26 is located in the transverse through hole 241b of the second avoidance hole 242, and then tighten the first fastener cap 251 so that the first fastener cap 251 is against one side of the protective cover 24, and tighten the second fastener cap 261 so that the second fastener cap 261 is against the other side of the protective cover 24, so that the protective cover 24 is installed.

[0047] In this embodiment, there are two first holes 231 and two second holes, respectively. The two first holes 231 and the two second holes are close to the two ends of the magnetic rod 23. The number of first fasteners 25 and first avoidance holes 241 corresponds to the number of first holes 231, and the number of second fasteners 26 and second avoidance holes 242 corresponds to the number of second holes. It can be understood that the number of first holes 231, second holes, first fasteners 25, first avoidance holes 241, second fasteners 26, and second avoidance holes 242 can be set according to actual conditions.

[0048] In actual application of the present invention, for the convenience of description, the magnetic rod mechanism 20 installed at the top of the base 10 is named as the top magnetic rod mechanism 20, and the magnetic rod mechanism 20 installed at the bottom of the base 10 is named as the bottom magnetic rod mechanism 20. In the initial state, the pole piece passes over the top magnetic rod mechanism 20. Under the action of the magnetic rod 23 of the top magnetic rod mechanism 20, the magnetic rod 23 of the top magnetic rod mechanism 20 can adsorb iron filings on the surface of the pole piece onto the protective cover 24 of the top magnetic rod mechanism 20. When a large amount of iron filings are already on the protective cover 24 of the top magnetic bar mechanism 20, the base 10 is driven by the driving member 31 to rotate 180 degrees so that the bottom magnetic bar mechanism 20 and the top magnetic bar mechanism 20 are swapped. At this time, the bottom magnetic bar mechanism 20 is located above the base 10 and below the pole piece, and the top magnetic bar mechanism 20 is located below the base 10. Under the action of the magnetic bar 23 of the bottom magnetic bar mechanism 20, the magnetic bar 23 of the bottom magnetic bar mechanism 20 can adsorb the iron filings on the surface of the pole piece onto the protective cover 24 of the bottom magnetic bar mechanism 20. The top magnetic bar mechanism 20 is then removed from the base 10, and the protective cover 24 of the top magnetic bar mechanism 20 is then removed from the magnetic bar 23 of the top magnetic bar mechanism 20. Since the protective cover 24 is not magnetic, the iron filings on the protective cover 24 of the top magnetic bar mechanism 20 can be directly shaken off, thereby achieving the cleaning of the iron filings on the protective cover 24 of the top magnetic bar mechanism 20. After cleaning, reinstall the top magnetic rod mechanism 20 on the top of the base 10. When there are a lot of iron filings on the protective cover 24 of the bottom magnetic rod mechanism 20, proceed as described above. In this way, the iron filings on the surface of the pole piece can be removed.

[0049] In other embodiments, the number of the magnetic bar mechanisms 20 can be other, such as three, four, etc. When there are three magnetic bar mechanisms 20, two of them are detachably mounted on the top and bottom ends of the base 10, respectively, and the other one is detachably mounted on one side of the base 10. When there are four magnetic bar mechanisms 20, two of them are detachably mounted on the top and bottom ends of the base 10, respectively, and the other two are detachably mounted on both sides of the base 10. It can be understood that the number of the magnetic bar mechanisms 20 can be set according to actual conditions.

[0050] The utility model can absorb the iron filings on the surface of the pole piece through the magnetic bar mechanism 20 provided, thereby removing the iron filings on the surface of the pole piece, ensuring the performance and stability of the battery. Moreover, when one of the magnetic bar mechanisms 20 absorbs the iron filings on the surface of the pole piece located above it, when the amount of iron filings absorbed by the magnetic bar mechanism 20 is relatively large, the base 10 and the two magnetic bar mechanisms 20 are driven to rotate by the driving mechanism 30, so that the two magnetic bar mechanisms 20 can be exchanged. In this way, the iron filings on the surface of the pole piece can continue to be absorbed by the other magnetic bar mechanism 20, and the magnetic bar mechanism 20 that has absorbed the iron filings can be disassembled for cleaning the iron filings. This process does not require shutdown operation, shortens the production time of the pole piece, improves production efficiency, and reduces production costs.

[0051] The utility model also provides a coating device, comprising the above-mentioned iron removal magnetic rod device.

Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
