DETAILED DESCRIPTION

[0050] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0051] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, indicating the orientation and position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0052] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0053] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0054] When assembling magnets, the magnets need to be separated from the magnet assembly. The separation method used is to slide the single magnet and the magnet assembly relative to each other along the surface of the magnet to separate the two. However, when the two slide relative to each other, scratches will appear on the surface of the magnet. When scratches appear on the surface of the magnet, the electroplated metal layer on the surface of the magnet is damaged, and the internal material of the magnet leaks out. After long-term use, the interior of the magnet is prone to rust and corrosion.

[0055] The present application provides a magnetic separation device 100, the magnetic separation device 100 is as follows Figure 1As shown, the magnetic separation device 100 includes: a silo unit 130, a first clamping unit 110, a magnetic sub-bin 140, a second clamping unit 120 and a first driving unit 150. The silo unit 130 is used to accommodate a magnet assembly 101, which is suitable for moving along a first direction Q1 in the silo unit 130. The magnet assembly 101 includes a plurality of magnets. When the magnet assembly 101 is accommodated in the silo unit 130, the plurality of magnets are arranged in sequence along the first direction Q1, and the end face of each magnet is in contact with the end face of the adjacent magnet; the first clamping unit 110 is used to clamp or loosen the magnet assembly 101 in the silo unit 130, and the first clamping unit 110 clamps the magnet assembly 101 by acting on the side of the magnet; the magnetic sub-bin 140 is arranged opposite to the outlet of the silo unit 130 along the first direction, and the magnetic sub-bin 140 is suitable for accommodating at least one magnet When the first clamping unit 110 releases the magnet combination 101, the magnet combination 101 moves along the first direction Q1 in the silo unit 130, so that at least one magnet facing the sub-magnetic bin 140 enters the sub-magnetic bin 140; the second clamping unit 120 is used to clamp or release at least one magnet in the sub-magnetic bin 140, and the second clamping unit 120 clamps the magnet by acting on the side of the magnet; the first driving unit 150 is used to drive the silo unit 130 or the sub-magnetic bin 140 to move along the first direction Q1 to move away from each other, so that the magnet combination 101 in the silo unit 130 and the at least one magnet in the sub-magnetic bin 140 are separated along the first direction Q1.

[0056] In some embodiments, as Figure 2As shown, the silo unit 130 is arranged along the first direction Q1, and a plurality of magnets are stored in the silo unit 130, and the plurality of magnets are stacked along the first direction Q1 to form a magnet combination 101. The first clamping unit 110 and the silo unit 130 cooperate with each other to clamp the magnet combination 101 from the side of the magnet combination 101 to prevent the magnet combination 101 from falling and damaging the magnet surface. It can be understood that the first clamping unit 110 and the silo unit 130 jointly clamp the side of the partial magnet adjacent to at least one magnet to be separated, and the partial magnet includes one or more magnets. The sub-magnetic bin 140 and the silo unit 130 are arranged relative to each other along the first direction Q1, and at least one magnet can enter the sub-magnetic bin 140 from the silo unit 130, thereby separating at least one magnet and the magnet combination 101 from each other along the first direction Q1. After at least one magnet enters the sub-magnetic bin 140, the second clamping unit 120 and the sub-magnetic bin 140 are arranged opposite to each other along the second direction Q2, and the second clamping unit 120 can move toward the position of the sub-magnetic bin 140. The two together clamp the side of at least one magnet in the sub-magnetic bin 140 along the second direction Q2 to avoid clamping the end face of the magnet, so that the magnet and the magnet combination 101 are separated from each other along the first direction Q1, avoiding the mutual sliding between the magnet surface and the surface of the magnet combination 101 along the second direction Q2 during the separation of the magnet from the magnet combination 101, that is, avoiding friction between the magnet surface and the lower surface of the magnet combination 101, thereby solving the problem of scratches on the magnet surface during separation.

[0057] In some embodiments, the end faces of multiple magnets are fitted together to form a magnet assembly 101. The end faces of the magnets are connected to the side faces of the magnets, and there is an angle between the end faces and the side faces, which is preferably 90°. The end face area of ​​the magnet is larger than the side face area of ​​the magnet. The magnet assembly 101 is arranged along the first direction Q1 and placed in the silo unit 130, which can reduce the space occupied by the silo unit 130 in the second direction Q2 and further reduce the space occupied by the magnet separation device 100 along the second direction Q2. The space utilization is more reasonable, so that during separation, position interference with other processing stations is avoided.

[0058] In some embodiments, the first direction Q1 is a vertical direction, the second direction Q2 is a horizontal direction, and the first direction Q1 and the second direction Q2 are perpendicular to each other.

[0059] In some embodiments, the magnetic separation chamber 140 may accommodate only one magnet, or two magnets, or three magnets, which is not limited here and is subject to actual magnetic separation requirements.

[0060] In some embodiments, as Figure 2As shown, the first drive unit 150 is used to drive the hopper unit 130 to move upward in the first direction Q1 to move away from each other, thereby completing the separation of the magnets; alternatively, the first drive unit 150 drives the magnetic separation chamber 140 to move downward in the first direction Q1 to move away from each other, without limitation herein. Specifically, the first drive unit 150 drives the hopper unit 130 and the magnetic separation chamber 140 to move away from each other in the first direction Q1 when at least one magnet and the magnet assembly 101 are both clamped.

[0061] In some embodiments, when the first driving unit 150 drives the magnetic separation chamber 140 to move downward along the first direction Q1, the equipment table needs to be raised so that the magnetic separation chamber 140 has space to move downward. A bracket can be set at the bottom of the equipment table to further raise the equipment table.

[0062] In some embodiments, the magnetic separation device 100 further includes a counterweight unit 170, such as Figure 3 As shown, the counterweight unit 170 is movably arranged on one side of the silo unit 130, and is suitable for reciprocating movement along the first direction Q1, where the first direction Q1 is a vertical direction. At least a portion of the counterweight unit 170 is arranged on the top of the magnet assembly 101, and is suitable for utilizing the gravity of the counterweight unit 170 to drive the magnet assembly 101 to move downward along the first direction Q1 in the silo unit 130.

[0063] In some embodiments, when the silo unit 130 is filled with magnets, the counterweight unit 170 is set on the top of the magnet assembly 101. The gravity of the counterweight unit 170 can be converted into continuous and stable downward pressure to ensure that the magnet assembly 101 moves smoothly in the vertical direction in the silo unit 130, thereby preventing equipment shutdown due to the jamming of the magnet assembly 101.

[0064] Moreover, compared with using active driving components such as motors and cylinders to push the magnet assembly 101 to move, the counterweight unit 170 applies pressure naturally through gravity without the need for an additional power source, avoiding mechanical problems such as motor failure and cylinder leakage, and reducing the maintenance frequency and cost of the equipment.

[0065] In some embodiments, the counterweight unit 170 includes a counterweight block 171, a pressure magnet 172, and a counterweight guide rail 173. The counterweight guide rail 173 is arranged adjacent to the silo unit 130 along the first direction Q1. The pressure magnet 172 is fixed on the counterweight block 171, and as shown in FIG. Figure 3 As shown, the counterweight block 171 is slidably mounted on the counterweight guide rail 173 , and at least a portion of the magnetic pressure member 172 extends into the silo unit 130 to push the magnet assembly 101 in the silo unit 130 to move downward along the first direction Q1 .

[0066] In some embodiments, the counterweight 171 is provided with an adsorption magnet, and the pressure magnet 172 is made of a magnetic conductive material, so that when the counterweight unit 170 presses the magnet assembly 101 downward, the pressure magnet 172 can always be adsorbed with the counterweight 171 to prevent the two from separating from each other. Figure 8 As shown, the counterweight 171 has a first through hole 1711, the pressure magnet 172 passes through the first through hole 1711, and the counterweight 171 is provided with two adsorption magnets, which are respectively arranged on both sides of the first through hole 1711 along the first direction Q1, so that the pressure magnet 172 is attracted by the adsorption magnet, so that the stop surface 1725 of the pressure magnet 172 is in contact with the side of the counterweight 171.

[0067] In some embodiments, as Figure 3 as well as Figure 5 As shown, the counterweight block 171 is slidably installed on the counterweight guide rail 173, thereby driving the pressure magnet part 172 to slide back and forth. The counterweight block 171 slides along the extension direction of the counterweight guide rail 173, which can strictly limit its movement trajectory, ensuring that the counterweight unit 170 only reciprocates along the first direction Q1, that is, the vertical direction, to avoid the counterweight block 171 from being offset or tilted due to the lateral magnetic force of the magnet combination 101 or the vibration of the equipment.

[0068] In some embodiments, when the counterweight block 171 slides to the bottom of the counterweight guide rail 173, the operator is required to manually push the counterweight block 171 upward so that the magnetic pressure piece 172 abuts against the top of the magnet assembly 101 in the replaced silo unit 130.

[0069] In some embodiments, as Figure 6 As shown, the magnetic pressure component 172 is provided with a magnetic pressure sheet 1721, which extends into the silo unit 130 to push the magnet combination 101 to move downward. The thickness of the magnetic pressure sheet 1721 is relatively small and can adapt to the space inside the silo unit 130 to avoid position interference in the silo unit 130, which causes the magnet combination 101 to move stuck.

[0070] Furthermore, if Figure 8 and Figure 9As shown, the counterweight 171 is further provided with a second through hole 1712 for passing a second locking member 1726. The second locking member 1726 passes through the second through hole 1712 and the second sliding slot 1724, so that the pressure magnet 172 can slide relative to the counterweight 171 along the first sliding slot 1722, thereby allowing the pressure magnet 172 to extend into or out of the silo unit 130, thereby facilitating the installation of the magnet assembly 101 in the silo unit 130 and preventing the pressure magnet 172 from being separated from the counterweight 171. For example, when the magnet assembly 101 in the silo unit 130 is separated and a new magnet assembly 101 needs to be installed, the pressure magnet 172 slides relative to the counterweight 171 along the second sliding slot 1724 to separate the pressure magnet 172 from the silo unit 130. After a new magnet assembly 101 is installed on the silo unit 130 , the magnetic pressing member 172 slides along the second sliding groove 1724 again to extend into the silo unit 130 .

[0071] Furthermore, if Figure 8 and Figure 9 As shown, the extending direction of the first through hole 1711 is perpendicular to the extending direction of the second through hole 1712 , and the extending direction of the second sliding groove 1724 is the same as the extending direction of the first through hole 1711 .

[0072] Furthermore, if Figure 6 As shown, the magnetic element 172 is further provided with a stop surface 1725 . When the magnetic element 172 and the counterweight 171 are mounted on each other, the side surface of the counterweight 171 abuts against the stop surface 1725 to limit the sliding of the counterweight 171 .

[0073] In this example, the counterweight block 171 is also provided with an adsorption magnet, and the pressure magnet component 172 is a magnetic conductive material. The pressure magnet component 172 can ensure that its position does not loosen under the attraction of the adsorption magnet, thereby ensuring that the pressure magnet component 172 can always press the magnet during the downward movement of the counterweight unit 170.

[0074] In one implementation, Figure 7 As shown, the magnetic member 172 is further provided with a first sliding groove 1722 , so that the magnetic sheet 1721 can slide along the first sliding groove 1722 relative to the counterweight 171 to adjust the length of the magnetic sheet 1721 extending into the silo unit 130 .

[0075] Furthermore, if Figure 7 As shown, the pressure magnet component 172 is also provided with a first locking component 1723. The first locking component 1723 passes through the pressure magnet sheet 1721 and then cooperates with the matching hole of the pressure magnet component 172, so that the first locking component 1723 can adjust the length of the pressure magnet sheet 1721 extending into the hopper unit 130. After the length adjustment is completed, the pressure magnet sheet 1721 is fixed in the first sliding groove 1722 by the first locking component 1723.

[0076] In this implementation, the length of the magnetic pressure plate 1721 extending into the silo unit 130 is adjustable to accommodate magnet assemblies 101 of varying sizes. For example, for larger magnet assemblies 101, the length of the magnetic pressure plate 1721 extending into the silo is correspondingly longer to better apply the weight of the counterweight 171 to the magnet assembly 101.

[0077] In another implementation, Figure 8 As shown, the counterweight 171 is provided with a plurality of second through holes 1712 along the extension direction of the first sliding slot 1722. These second through holes 1712 are used to adjust the length of the magnetic pressure plate 1721 extending into the silo unit 130. When the second locking member 1726 passes through the second through hole 1712 closer to the silo unit 130, the magnetic pressure plate 1721 extends shorter into the silo unit 130. When the second locking member 1726 passes through the second through hole 1712 farther from the silo unit 130, the magnetic pressure plate 1721 extends longer into the silo unit 130.

[0078] In some embodiments, as Figure 2 As shown, the first clamping unit 110 is equipped with a mounting plate 113 and a photoelectric switch 114. The photoelectric switch 114 is used to detect the position of the piezo-magnetic element 172. The mounting plate 113 is disposed at the lower end of the counterweight unit 170. The photoelectric switch 114 and the piezo-magnetic element 172 vertically overlap. Furthermore, the piezo-magnetic element 172 is thinner in the portion that vertically overlaps the photoelectric switch 114.

[0079] It can be understood that a silo body 131 is provided in the silo unit 130, and the silo body 131 is filled with a magnet combination 101. When the silo body 131 is full of magnets, the piezoelectric component 172 is located at the end of the counterweight guide rail 173 away from the first clamping unit 110. When the magnets in the silo body 131 continue to decrease, the height of the piezoelectric component 172 also continues to decrease. When the silo body 131 is empty, part of the piezoelectric component 172 falls between the receiving end and the transmitting end of the photoelectric switch 114, blocking the signal between the receiving end and the transmitting end of the photoelectric switch 114, thereby triggering the photoelectric switch 114, and then reminding the operator to replace the silo body 131.

[0080] In other embodiments, the photoelectric switch 114 can also be mounted on the inner wall of the silo body 131, adapted to monitor whether the silo unit 130 is empty. The photoelectric switch 114 includes a transmitter and a receiver, with the transmitter emitting an electrical signal and the receiver receiving the signal. Specifically, the photoelectric switch 114 is mounted on the inner wall near the silo outlet, with the transmitter and receiver respectively disposed on two opposing side walls of the silo body 131. It should be understood that the height of the magnet assembly 101 in the first direction Q1 is related to the number of magnets. When the number of magnets in the silo unit 130 is small, the height of the magnet assembly 101 will be low, and the signal emitted by the transmitter will be received by the receiver, thereby signaling a shortage of material in the silo unit 130. However, when the number of magnets in the silo unit 130 is large, the receiver will be blocked by the magnet assembly 101 and unable to receive the electrical signal from the transmitter, indicating that the number of magnets in the silo unit 130 is sufficient.

[0081] In some embodiments, as Figure 5 As shown, the silo unit 130 further includes: a silo body 131, a cover plate 132 and a fixing member 134. Figures 10 and 11 As shown, the hopper body 131 is provided with a first accommodating groove 1311, which is suitable for accommodating the magnet combination 101. The cover 132 covers at least a portion of the first accommodating groove 1311, and the cover 132 has a gap, so that at least a portion of the magnetic pressure part 172 can pass through the gap and contact the top of the magnet combination 101.

[0082] In some embodiments, the silo unit 130 includes a silo body 131 and a cover plate 132, the cover plate 132 covers at least a portion of the first receiving groove 1311. Figure 5 It can be seen that there is a gap between the cover plates 132, so that the pressure magnetic sheet 1721 can pass through the gap, and then the pressure magnetic sheet 1721 and the top of the magnet combination 101 are pressed against each other, so as to rely on the gravity of the counterweight block 171 to push the magnet combination 101 to move, which can ensure that the driving force of the pressure magnetic sheet 1721 directly acts on the magnet combination 101, and can limit the shaking of the magnet combination 101 through the cover plate 132 to prevent the magnet combination 101 from escaping from the first accommodating groove 1311.

[0083] In some embodiments, as Figure 1 As shown, the silo unit 130 further includes a fixing member 134. Figure 12 As shown, the fixing member 134 is provided with a fixing groove 1342, and the fixing member 134 is sleeved on the outside of the silo body 131, so that the silo body 131 and the cover plate 132 are installed in the fixing member 134, wherein, as shown in FIG. Figure 12As shown, a protrusion 13421 is provided in the fixing groove 1342. When the silo body 131 is placed in the fixing groove 1342, the end of the silo body 131 abuts against the protrusion 13421 to limit the downward movement of the silo body 131 along the first direction Q1, thereby preventing the silo body 131 from separating from the fixing member 134.

[0084] Alternatively, the protrusion 13421 is not provided at the bottom of the fixing member 134, so that the hopper body 131 passes through the fixing member 134. When separating the magnet, the first accommodating groove 1311 of the hopper body 131 can be arranged relative to the second step 142 along the first direction Q1, thereby separating the magnet and the magnet combination 101 from each other.

[0085] In some embodiments, as Figure 13 As shown, the fixing member 134 is also provided with a fixing cover plate 1343, thereby limiting the silo body 131 in the fixing groove 1342; wherein, there is a gap between the fixing cover plates 1343 to prevent the fixing cover plates 1343 from interfering with the position of the pressure magnetic sheet 1721, and the gap of the fixing cover plates 1343 is larger than the gap of the cover plate 132, so that the fixing member 134 can cooperate with more silo bodies 131, avoiding the situation where the gap of the fixing cover plates 1343 is too small and the pressure magnetic sheet 1721 cannot extend into the silo body 131.

[0086] In some embodiments, the hopper unit 130 is provided with a clamping window 1341, which is arranged opposite to the hopper body 131 along a first direction Q1. The clamping window 1341 is provided with a second receiving groove 13411 for receiving the magnet assembly 101, and the bottom of the clamping window 1341 forms an exit of the hopper unit 130. The magnet assembly 101 is adapted to move downward from the first receiving groove 1311 along the first direction Q1 into the second receiving groove 13411. The first clamping unit 110 includes a first clamping block 111 and a first clamping cylinder 112. The first clamping block 111 is arranged opposite to the clamping window 1341 along a second direction Q2. The first clamping cylinder 112 is configured to drive the first clamping block 111 to move along the second direction Q2 toward the clamping window 1341 to clamp the side of the magnet assembly 101. The first direction Q1 and the second direction Q2 are perpendicular to each other. Specifically, the bottom of the clamping window 1341 and the bottom of the first clamping block 111 are located on the same horizontal plane.

[0087] In some embodiments, the first receiving groove 1311 of the hopper body 131 and the second receiving groove 13411 of the clamping window 1341 are arranged relative to each other along a first direction Q1, so that at least a portion of the magnet assembly 101 in the hopper body 131 slides into the clamping window 1341, preventing the magnet assembly 101 from getting stuck during the sliding process. The clamping window 1341 is provided at the end of the hopper unit 130 near the first clamping block 111. The first clamping cylinder 112 drives the first clamping block 111 to move along the second direction Q2 toward the clamping window 1341 to clamp the side of the magnet assembly 101.

[0088] In some embodiments, chamfers are provided in the first accommodating groove 1311 and the second accommodating groove 13411 to reserve space for avoiding the corners of the magnet. When the magnet combination 101 is in the first accommodating groove 1311 and the second accommodating groove 13411, the two corners of the magnet are prevented from contacting each other with the inside of the accommodating groove, thereby preventing the corners of the magnet from cracking.

[0089] In some embodiments, as Figure 3 As shown, the first clamping cylinder 112 drives the first clamping block 111 to move by air pressure. Compared with other driving methods such as motors, it has the characteristics of rapid action and stable output force. When the magnet assembly 101 needs to be clamped, the first clamping cylinder 112 can quickly push the first clamping block 111 to move along the second direction Q2 and apply stable pressure; it can also quickly reset when released. The clamping and loosening process does not require complex transmission, and the response time is short, which is suitable for scenarios that require high-frequency clamping or loosening in the magnet separation device 100. In addition, the output force of the first clamping cylinder 112 can be adjusted by adjusting the size of the air pressure, and the appropriate clamping force can be set according to the material, strength and other characteristics of the magnet assembly 101, which not only ensures that the magnet assembly 101 will not loosen or shift during subsequent separation or movement when clamped, but also avoids deformation, fragmentation or scratching of the magnet due to excessive clamping force.

[0090] In some embodiments, as Figure 15 As shown, the first clamping block 111 is provided with a clamping surface 1111, and the clamping surface 1111 and the fixing member 134 are arranged opposite to each other along the second direction Q2. Figure 12 As shown, the clamping window 1341 is specifically provided on the fixing member 134, and the fixing member 134 is further provided with a fixing groove 1342. The hopper body 131 is provided in the fixing groove 1342, thereby limiting the setting position of the hopper body 131; when the first clamping unit 110 and the hopper unit 130 are close to each other, the clamping surface 1111 and the clamping window 1341 are close to each other, so that the two cooperate with each other to jointly clamp the magnet assembly 101, as shown in FIG. Figure 13 and Figure 14 As shown. Figure 4As shown, the magnet assembly 101 protrudes relative to the plane where the clamping window 1341 is located, so that the clamping surface 1111 and the side surface of the magnet assembly 101 abut against each other, thereby clamping the magnet assembly 101.

[0091] Preferably, the side surface of the magnet assembly 101 protrudes from the plane where the clamping window 1341 is located. The distance between the side surface of the magnet assembly 101 and the plane where the clamping window 1341 is located can be determined by the size of the magnet assembly 101. For example, the distance is 0.1 mm. Alternatively, for a larger magnet assembly 101, the distance can be 0.2 mm.

[0092] In some embodiments, if the protrusion 13421 is not provided on the fixing member 134 and the hopper body 131 passes through the fixing member 134 , the clamping window 1341 is recessed on the hopper body 131 , and the clamping surface 1111 and the clamping window 1341 are close to each other to jointly clamp the magnet assembly 101 .

[0093] In one implementation, when the position of the pressure magnet 172 is lower than the preset position, the pressure magnet 172 of the counterweight unit 170 blocks the photoelectric switch 114, and the photoelectric switch 114 triggers a loading reminder for the silo body 131. The photoelectric switch 114 feeds back a signal to the device, and the device outputs a signal that loading is required and alarms to stop the machine, waiting for the operator to replace the silo body 131. When the pressure magnet 172 reaches the preset position, the height of the lower surface of the pressure magnet sheet 1721 (i.e., the upper surface of the magnet assembly 101) is lower than the lower surface of the silo body 131 (i.e., the upper surface of the clamping window 1341). At this time, the magnet assembly 101 no longer exists in the silo body 131, so the photoelectric switch 114 can trigger a loading reminder for the silo body 131.

[0094] Specifically, when the magnetic pressure element 172 reaches the preset position, the height difference between the lower surface of the magnetic pressure piece 1721 and the lower surface of the hopper body 131 is 2mm to 3mm. In other words, the height difference between the upper surface of the magnet assembly 101 in the clamping window 1341 and the lower surface of the hopper body 131 is 2mm to 3mm. This prevents damage to the magnets in the hopper body 131 caused by vertical drop after replacement.

[0095] In some embodiments, the silo unit 130 is further provided with a magnetic block 133, which is arranged at the top of the silo unit 130 so that the magnetic block 133 generates a magnetic attraction force on the magnet combination 101 to prevent the magnet combination 101 from shifting in the silo unit 130 when there is no external force.

[0096] Optionally, the setting position of the magnetic block 133 can be set according to the height of the magnet combination 101. It can be understood that the magnetic block 133 can slide in the silo unit 130 along the first direction Q1, and then cooperate with the magnet combinations 101 of different heights.

[0097] It should be understood that if Figure 10 and Figure 11 As shown, Figure 11 yes Figure 10 The enlarged view of the middle area B shows that when the hopper body 131 is replaced, the magnet assembly 101 inside the hopper body 131 is not clamped. Therefore, in order to prevent the magnet assembly 101 from falling during the replacement process, a magnetic attraction block 133 is provided. The magnetic attraction block 133 generates a magnetic attraction force on the magnet assembly 101. When the hopper body 131 is installed in the fixing member 134, the magnet assembly 101 falls, and the top of the magnet assembly 101 separates from the magnetic attraction block 133, thereby weakening the magnetic attraction force on the magnet assembly 101. Furthermore, the counterweight unit 170 is also used to separate the magnet assembly 101 from the magnetic attraction block 133 to achieve subsequent automatic feeding.

[0098] In some embodiments, as Figure 16 as well as Figure 17 As shown, the magnetic sub-bin 140 includes: a first step 141 and a second step 142. The first step 141 and the second step 142 are connected by a connecting side 145. The connecting side 145 abuts against the side of at least one magnet. The first step 141 is suitable for abutting against the bottom of the silo unit 130, and the second step 142 is suitable for abutting against at least one magnet. The plane where the first step 141 is located is higher than the plane where the second step 142 is located.

[0099] In some embodiments, the magnetic separation chamber 140 is provided with a first step 141 and a second step 142 connected by a connecting side surface 145, and there is a height difference between the first step 141 and the second step 142, and the height difference is smaller than the height of at least one magnet to be separated, and the magnet in the magnetic separation chamber 140 is placed on the second step 142. Figure 4 As shown, the distance between the side of the magnet assembly 101 away from the first clamping block 111 and the side wall of the silo unit 130 away from the first clamping block 111 along the second direction Q2 is b; Figure 16As shown, the distance between the limiting surface 1411 of the first step 141 and the connecting side surface 145 along the second direction Q2 is a, and b is equal to a. When separating the magnets, the bottom of the hopper unit 130 is placed on the first step 141. At this time, the counterweight unit 170 pushes the magnet assembly 101 downward. Due to the height difference between the first step 141 and the second step 142, the magnet assembly 101 can be placed on the second step 142, thereby allowing the magnet to separate from the magnet assembly 101 along the first direction Q1.

[0100] In some embodiments, b is equal to a, so that the end of the magnet assembly 101 can be arranged opposite to the second step 142 along the first direction Q1, avoiding misalignment between the magnet assembly 101 and the second step 142 and affecting the separation of the magnets.

[0101] In some embodiments, as Figure 17 As shown, the height of the connecting side surface 145 is less than the height of at least one magnet. This prevents the second step 142 and the second clamping block 122 from clamping adjacent magnets and causing them to be separated incorrectly when the magnets are separated. The length of the second step 142 along the second direction Q2 is less than the length of at least one magnet along the second direction Q2, allowing the connecting side surface 145 to cooperate with the first side surface 1221 of the second clamping block 122, thereby stably clamping the magnets. Figure 19 As shown, during the clamping process, the first side surface 1221 will approach the mating surface 144, but will not fit together, thereby stably clamping the magnet; if the length of the second step 142 is greater than or equal to the length of the magnet, the first side surface 1221 and the mating surface 144 will fit together, resulting in the magnet not being able to fully receive the clamping force, and the magnet will easily shake during separation, affecting the efficiency of magnetic separation.

[0102] In some embodiments, the first step 141 has a limiting surface 1411, such as Figure 16 As shown, the limiting surface 1411 is arranged on the side away from the second step 142. When the bottom of the silo unit 130 is placed on the first step 141, the side of the silo unit 130 and the limiting surface 1411 abut against each other to determine the position of the silo unit 130, ensuring that the magnet can be placed on the second step 142 to prevent misalignment.

[0103] In some embodiments, as Figure 16 As shown, the magnetic compartment 140 is provided with a mating surface 144, as shown in FIG. Figure 18 As shown, the second clamping block 122 is provided with a first side surface 1221. When the magnetic sub-chassis 140 and the second clamping unit 120 cooperate with each other to clamp the magnet, as shown in FIG. Figure 18 As shown, the first side surface 1221 and the mating surface 144 are close to each other, wherein Figure 17As shown, the side surface of the magnet protrudes from the mating surface 144 , so that the second clamping block 122 can cooperate with the connecting side surface 145 to clamp the magnet.

[0104] Preferably, the distance between the side of the magnet and the mating surface 144 can be 0.1mm, 0.15mm or 0.2mm, which is not limited here. Since the magnetic compartment 140 can accommodate at least one magnet, the thickness of the portion of the magnet protruding from the mating surface 144 can be 0.1mm, 0.2mm or 0.3mm.

[0105] In some embodiments, the second step 142 has a rounded corner 1421, such as Figure 17 As shown, the rounded corner 1421 is provided on the side of the second step 142 close to the first step 141, and the rounded corner 1421 is recessed relative to the plane where the second step 142 is located, thereby avoiding the corners of the magnet. Magnets are usually brittle, and the corners of the magnet are weak areas where stress is concentrated. If the magnet is placed on the second step 142, the corners of the magnet are in direct contact with the second step 142, which may easily cause the corners of the magnet to crack or fall off, affecting the magnetic properties and service life. Therefore, the recessed setting of the rounded corner 1421 reserves space to avoid the corners of the magnet, reduces the direct contact between the corners of the magnet and the second step 142, and reduces the risk of collision damage to the magnet.

[0106] In some embodiments, the magnetic separation device 100 further includes a second driving unit 160, which is used to drive the magnetic separation chamber 140 and the second clamping unit 120 to move along the second direction Q2 to the magnet assembly position. Figure 1 As shown, the second driving unit 160 is arranged on one side of the magnetic separation bin 140 and the second clamping unit 120, thereby pushing the two to move to the assembly position for assembly, reducing the intermediate links between the separation and assembly of the magnets. During the movement, the two always clamp the magnets to prevent them from falling during the movement, avoiding the adsorption of impurities due to falling during transportation, and improving production efficiency.

[0107] In some embodiments, the second clamping unit 120 includes a second clamping block 122 and a second clamping cylinder 121. The second clamping block 122 and the magnetic sub-bin 140 are arranged opposite to each other along the second direction Q2. The second clamping cylinder 121 drives the second clamping block 122 to slide back and forth along the second direction Q2. The first side surface 1221 of the second clamping block 122 and the connecting side surface 145 and the second step 142 form a clamping space 143 to clamp at least one magnet.

[0108] In some embodiments, as Figure 19As shown, the second clamping unit 120 includes a second clamping cylinder 121 and a second clamping block 122. The second clamping cylinder 121 can drive the second clamping block 122 to move toward the direction where the magnetic sub-bin 140 is located, so that a clamping space 143 is formed between the second clamping block 122, the second step 142 and the connecting side 145. Figure 20 As shown, the magnet is then confined on the magnetic separation chamber 140, completing the separation of the magnet and the magnet assembly 101. Specifically, the lower surface of the second clamping block 122 and the first step 141 are on the same horizontal plane.

[0109] In some embodiments, as Figure 21 As shown, the first driving unit 150 includes: a first driving cylinder 151 and a limit member 152. The first driving cylinder 151 drives the silo unit 130 to move back and forth along the first direction Q1. The limit member 152 is arranged at the end of the silo unit 130 close to the sub-magnetic bin 140. The limit member 152 is used to adjust the gap between the silo unit 130 and the sub-magnetic bin 140 when the magnet at the end of the magnet combination 101 falls on the second step 142, or the limit member 152 is used to adjust the gap between the first clamping block 111 and the second clamping block 122 to prevent the first clamping block 111 from clamping the end magnet and to prevent the second clamping block 122 from clamping the second magnet. It can be understood that the limit member 152 is used to adjust the minimum gap between the bottom of the silo unit 130 and the magnetic separation bin 140, specifically the minimum gap between the bottom of the clamping window 1341 and the first step 141, or the limit member 152 is used to adjust the minimum gap between the first clamping block 111 and the second clamping block 122, which can limit the maximum height of the silo unit 130 falling, prevent the silo unit 130 from colliding with the magnetic separation bin 140 when falling, and prevent the first clamping block 111 from clamping at least one magnet that needs to be separated, and prevent the second clamping block 122 from clamping other magnets that do not need to be separated.

[0110] In some embodiments, when the magnetic separation bin 140 and the second clamping unit 120 clamp the magnet, and the silo unit 130 and the first clamping unit 110 clamp the magnet assembly 101, the first drive cylinder 151 drives the silo unit 130 to move back and forth along the first direction Q1 to complete the separation of the magnet and the magnet assembly 101. By driving the silo unit 130 to move by the cylinder, the response time is short, and the speed of the silo unit 130 movement can be adjusted by adjusting the air pressure of the cylinder. Furthermore, the silo unit 130, the first clamping unit 110, and the counterweight unit 170 can be driven as a whole by the first drive cylinder 151.

[0111] In some embodiments, as Figure 21As shown, the limiting member 152 is fixed to the mounting member 153. The limiting member 152 protrudes relative to the surface on which the mounting member 153 is located. This causes the silo unit 130, the first clamping unit 110, and the counterweight unit 170 to contact the end of the limiting member 152 when moving downward along the first direction Q1, thereby limiting the maximum downward movement distance of the silo unit 130. By adjusting the height of the limiting member 152 relative to the mounting member 153, the maximum downward movement distance of the silo unit 130 is adjusted, thereby adjusting the minimum gap between the silo unit 130 and the magnetic sub-bin 140, thereby preventing the silo unit 130 from colliding with the magnetic sub-bin 140.

[0112] Preferably, the minimum gap between the lower surface of the silo unit 130 and the first step 141 of the magnetic sub-bin 140 is 0.1mm, 0.15mm or 0.2mm, or the minimum gap between the lower surface of the first clamping unit 110 and the upper surface of the second clamping unit 120 is 0.1mm, 0.15mm or 0.2mm.

[0113] In some embodiments, as Figures 22A-22B As shown, the magnet combination 101 includes a first magnet 1011 and a second magnet 1012. The end face of the first magnet 1011 and the end face of the second magnet 1012 are in contact with each other along the first direction Q1. The first magnet 1011 and the magnetic separation bin 140 are closest to each other in the vertical direction. When the magnetic separation bin 140 accommodates the first magnet 1011, the silo unit 130 accommodates the second magnet 1012.

[0114] It should be understood that: Figures 22A-22B As shown, the magnet of the magnet assembly 101 close to the magnetic separation chamber 140 is the first magnet 1011, and the magnet that is in contact with the first magnet 1011 is the second magnet 1012. When the magnet is separated from the magnet assembly 101, the magnetic separation chamber 140 and the second clamping unit 120 clamp the first magnet 1011, and the clamping window 1341 and the first clamping block 111 clamp the second magnet 1012 and other magnets adjacent to the second magnet 1012.

[0115] In some embodiments, the separation method of the magnetic separation device 100 provided in the present application is as follows: the first driving unit 150 drives the silo unit 130 to move downward along the first direction Q1. At this time, the first clamping unit 110 cooperates with the silo unit 130 to clamp the magnet assembly 101 in the silo unit 130 to prevent the magnet assembly 101 from falling. The second clamping unit 120 and the sub-magnetic bin 140 move away from each other, and the silo unit 130 moves to the top of the sub-magnetic bin 140. Due to the restriction of the limiter 152, the collision between the silo unit 130 and the sub-magnetic bin 140 is avoided. The first clamping unit 110 is loosened, causing the magnet assembly 101 to fall onto the second step 142 of the sub-magnetic bin 140. Since the gap between the silo unit 130 and the sub-magnetic bin 140 is small, the magnet assembly 101 will not be scratched after it falls. When a magnet is placed on the second step 142, the second clamping unit 120 moves toward the direction of the sub-magnetic bin 140, so that the second clamping block 122 cooperates with the second step 142 to clamp the magnet, and the first clamping unit 110 approaches the silo unit 130 again to clamp the remaining magnet combination 101. After being clamped in place, the first drive unit 150 drives the silo unit 130 and the first clamping unit 110 to move upward along the first direction Q1, so that the magnet and the magnet combination 101 are separated from each other along the first direction Q1, thereby avoiding relative sliding of the ends of the magnet and the magnet combination 101 along the second direction Q2, thereby solving the problem that the surface of the magnet is easily scratched during separation. After the silo unit 130 and the sub-magnetic bin 140 move away from each other, the second drive unit 160 drives the sub-magnetic bin 140 to move to the assembly position along the second direction Q2, completing the separation of the magnet and the magnet combination 101.

[0116] In some embodiments, when the hopper body 131 is replaced, magnets are still present in the clamping window 1341. The first clamping block 111 and the clamping window 1341 jointly clamp the remaining magnets, and the magnetic pressure element 172 is pulled along the second sliding groove 1724, causing the magnetic pressure piece 1721 to disengage from the fixing groove 1342. This prevents the hopper body 131 from colliding with the magnetic pressure piece 1721 when the hopper body 131 is installed, and the hopper body 131 is then pulled out of the fixing member 134. After the hopper body 131 is filled with the magnet assembly 101, it is installed on the fixing member 134 again. After the installation of the silo body 131 is completed, the counterweight unit 170 is pulled upward so that the pressure magnetic sheet 1721 is at the same height as the top of the magnet combination 101 in the first direction Q1, and then the pressure magnetic sheet 1721 is pushed into the first accommodating groove 1311 along the second sliding groove 1724.
