Description

Technical Field

[0001] This utility model relates to the technical field of material handling devices, and in particular to a magnetic material handling device. Background Technology

[0002] In the battery pack assembly process, the potential for damage from drops or scratches on the casing during cell handling has become a key factor affecting product yield and customer satisfaction. Especially in the context of large-scale, automated production in the new energy battery industry, traditional manual cell handling is not only inefficient but also prone to surface scratches, deformation from drops, and short circuits, severely restricting battery production efficiency, reliability, and quality consistency. Therefore, it is necessary to develop novel cell handling devices to optimize cell handling and systematically manage quality risks during the process. Designing such devices is a pressing technical challenge in the battery manufacturing industry. Utility Model Content

[0003] This utility model provides a magnetic material handling device, which mainly solves the technical problem of how to optimize the handling and placement of battery cells to improve the handling and placement efficiency and reduce the risk of surface scratches, deformation from falling to the ground, or short circuits of battery cells.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A magnetic material handling device includes a hand-held base, a sliding bracket, an elastic element, and multiple magnets;

[0006] The sliding bracket is slidably connected to the handheld base along the first direction. The elastic element is connected between the handheld base and the sliding bracket. The sliding bracket is subject to the elastic force of the elastic element and has a tendency to slide relative to the handheld base along the first direction. The plurality of magnets are fixed to one end of the sliding bracket along the first direction and are used to magnetically attract the object to be picked up.

[0007] Let the end face of the handheld base along the first direction be the first end face. The first end face is provided with a clearance hole for avoiding the reciprocating movement of the magnet along the first direction. The first end face also serves as a limiting surface for restricting the object from entering the clearance hole along the opposite direction of the first direction following the magnet.

[0008] In one of the technical solutions, the handheld base includes a handle, a guide rod, and a contact bracket arranged sequentially along the first direction;

[0009] The guide rod is fixedly connected to the handle and the contact bracket respectively. The sliding bracket is located between the handle and the contact bracket and is slidably connected to the guide rod. The elastic element is connected between the handle and the contact bracket. A plurality of magnets are fixed to the end of the sliding bracket facing away from the handle. The end face of the contact bracket facing away from the handle is the first end face.

[0010] In one of the technical solutions, two guide rods are fixed between the handle and the contact bracket, and the sliding bracket is slidably connected to the two guide rods respectively. The elastic element is sleeved on both guide rods.

[0011] In one of the technical solutions, a plurality of the magnets are arranged between the two guide rods.

[0012] In one of the technical solutions, the sliding bracket includes a sliding plate, a left side plate, a right side plate, and a mounting plate;

[0013] The slide plate is slidably connected to the two guide rods respectively. The mounting plate is located in the first direction of the slide plate. The left side plate fixes one end of the slide plate and the mounting plate respectively. The right side plate fixes the other end of the slide plate and the mounting plate respectively, so that the slide plate, the left side plate, the right side plate and the mounting plate together form an annular structure with a central hole inside. The elastic element is located between the slide plate and the handle. The multiple magnets are all fixed to the mounting plate.

[0014] In one of the technical solutions, two linear bearings are fixed on the slide plate, and two guide rods are inserted into the two linear bearings in a corresponding manner.

[0015] In one of the technical solutions, the mounting plate has multiple mounting holes on the side facing the slide plate, and each mounting hole is used for bolting a corresponding magnet.

[0016] In one of the technical solutions, the mounting plate is provided with a through hole to allow the guide rod to pass through.

[0017] In one technical solution, the end face of the contact bracket facing the handle is designated as the second end face. When the sliding bracket is pressed against the second end face by the elastic force of the elastic element, the plurality of magnets are flush with the first end face or extend beyond the first end face along the first direction.

[0018] In one of the technical solutions, the number of clearance holes is the same as the number of magnets, the positions of the multiple clearance holes correspond one-to-one with the positions of the multiple magnets, and the size of the clearance holes is smaller than the outer dimensions of the object to be picked up.

[0019] Compared with the prior art, the magnetic material handling device provided by this utility model has at least the following beneficial effects:

[0020] Taking battery cells as an example, when using this solution, the operator holds the handheld base and moves the picking device above multiple battery cells, and uses multiple magnets to magnetically attract the multiple battery cells. Then, holding the handheld base, the entire picking device with multiple magnetically attracted battery cells is moved to the required unloading position. Then, by manually pulling the sliding bracket in the opposite direction of the first direction, the multiple magnets are completely received into the clearance hole. At this time, because the multiple battery cells are restricted by the first end face on the handheld base and cannot follow the corresponding magnet into the clearance hole, the multiple battery cells will separate from the corresponding magnets, thereby achieving the purpose of unloading multiple battery cells to the designated position. When the sliding bracket is released, the sliding bracket will, under the elastic force of the elastic element, reliably reset the multiple magnets to the initial position in the positive direction of the first direction, so that the multiple magnets can magnetically pick up other battery cells again.

[0021] The magnetic material handling device using this solution can handle multiple battery cells more conveniently, reliably, and stably, thereby improving the efficiency of cell handling. In addition, since the operator's hands do not directly contact the battery cells, the risk of scratches on the battery cell casing, deformation from falling, or short circuits caused by manual contact with the battery cells is greatly reduced, ensuring the integrity, safety, reliability, and quality consistency of the battery cells.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please refer to the following: Figure 1 and Figure 2This utility model provides a magnetic material picking device, which mainly includes a hand-held base 1, a sliding bracket 2, an elastic element 3, and multiple magnets 4. The sliding bracket 2 is slidably connected to the hand-held base 1 along the first direction Z. The elastic element 3 is preferably a spring and is disposed between the hand-held base 1 and the sliding bracket 2. The sliding bracket 2 is subjected to the elastic force of the elastic element 3 and has a tendency to slide relative to the hand-held base 1 along the first direction Z. The multiple magnets 4 are all fixed to the end of the sliding bracket 2 facing away from the elastic element 3 and are used to magnetically pick up the object to be picked up. To illustrate more clearly, let's assume that the end face of the handheld base 1 along the first direction Z is the first end face 131. The first end face 131 is provided with a clearance hole 132. This clearance hole 132 is used to prevent the magnet 4 from reciprocating along the first direction Z, so that the magnet 4 can magnetically attract the object to be picked up. In addition, the number of clearance holes 132 is the same as the number of magnets 4. The positions of multiple clearance holes 132 correspond one-to-one with the positions of multiple magnets 4, and the size of each clearance hole 132 is smaller than the outer dimensions of the object to be picked up, so that the first end face 131 can serve as a limiting surface for restricting the object from following the magnet 4 into the clearance hole 132 in the opposite direction of the first direction Z.

[0033] Specifically, taking battery cell 5 as an example, when using this solution, if... Figure 2 As shown, the operator holds the handheld base 1 and moves the material handling device above multiple battery cells 5, and uses multiple magnets 4 to magnetically attract the multiple battery cells 5. Then, holding the handheld base 1, the operator moves the entire material handling device with multiple magnetically attracted battery cells 5 to the required unloading position. Then, by manually pulling the sliding bracket 2 in the opposite direction of the first direction Z, the multiple magnets 4 are completely received into the clearance hole 132. At this time, because the multiple battery cells 5 are restricted by the first end face 131 on the handheld base 1, they cannot follow the corresponding magnets 4 into the clearance hole 132. Therefore, the multiple battery cells 5 will separate from the corresponding magnets 4, thereby achieving the purpose of unloading multiple battery cells 5 to the designated position. When the sliding bracket 2 is released, the sliding bracket 2 will, under the elastic force of the elastic member 3, reliably reset the multiple magnets 4 to the initial position in the positive direction of the first direction Z, so that the multiple magnets 4 can magnetically attract other battery cells 5 again.

[0034] Please refer to it again. Figure 1The handheld base 1 specifically includes a handle 11, a guide rod 12, and a contact bracket 13 arranged sequentially along the first direction Z. The guide rod 12 is fixedly connected to both the handle 11 and the contact bracket 13. The aforementioned sliding bracket 2 is designed between the handle 11 and the contact bracket 13 and is slidably connected to the guide rod 12. The aforementioned elastic element 3 is connected between the handle 11 and the contact bracket 13. Multiple magnets 4 are actually fixed to the end of the sliding bracket 2 facing away from the handle 11. The end face of the contact bracket 13 facing away from the handle 11 is actually the aforementioned first end face 131. By designing the handheld base 1 in this way, the operator can hold the handle 11 to operate the entire material handling device. Furthermore, it facilitates the sliding connection between the handheld base 1 and the sliding bracket 2. Moreover, the sliding bracket 2 can be placed in the middle area of ​​the handheld base 1, thereby allowing the first end face 131 of the handheld base 1 to serve as a limiting surface. Preferably, two guide rods 12 are fixed between the handle 11 and the contact bracket 13. Correspondingly, the sliding bracket 2 is slidably connected to the two guide rods 12 to improve the stability of the sliding bracket 2 relative to the handheld base 1. Based on this, the aforementioned elastic element 3 is sleeved on both guide rods 12, so that the guide rods 12 not only play a guiding role but also play a role in restricting the elastic element 3, ensuring that the elastic direction of the elastic element 3 is mainly oriented towards the first direction Z. More preferably, multiple magnets 4 are arranged between the two guide rods 12 to ensure that the distance between the two guide rods 12 is large enough to further improve the sliding stability of the sliding bracket 2.

[0035] Please refer to it again. Figure 1 Let the end face of the contact bracket 13 facing the handle 11 be the second end face 133. When the sliding bracket 2 is not pulled, it is pressed against the second end face 133 by the elastic force of the elastic element 3, so that the contact bracket 13 also has the function of limiting the position of the sliding bracket 2 to prevent the sliding bracket 2 from sliding off the guide rod 12. More specifically, when the sliding bracket 2 is pressed against the second end face 133 by the elastic force of the elastic element 3, the multiple magnets 4 are flush with the first end face 131 or extend beyond the first end face 131 along the first direction Z, so as to ensure that the multiple magnets 4 can reliably attract the corresponding battery cell 5.

[0036] Please refer to the following: Figure 1 and Figure 2The sliding bracket 2 specifically includes a slide plate 21, a left side plate 22, a right side plate 23, and a mounting plate 24. The slide plate 21 is slidably connected to two guide rods 12. The mounting plate 24 is located on the slide plate 21 in the first direction Z. The left side plate 22 fixes one end of the slide plate 21 and the mounting plate 24, and the right side plate 23 fixes the other end of the slide plate 21 and the mounting plate 24, so that the slide plate 21, the left side plate 22, the right side plate 23, and the mounting plate 24 together form an annular structure with a central hole 25 inside. In use, the operator's fingers can be inserted into this central hole 25, making it easier to lift the sliding bracket 2 in the opposite direction of the first direction Z while holding the handle 11, thereby further improving the convenience of operation. In fact, the elastic element 3 mentioned above is located between the slide plate 21 and the handle 11, and the multiple magnets 4 mentioned above are all fixed on the mounting plate 24. Preferably, the mounting plate 24 has multiple mounting holes 241 on the side facing the slide plate 21, and these mounting holes 241 are all used for bolting a corresponding magnet 4. Preferably, two linear bearings 26 are fixed on the slide plate 21, and two guide rods 12 are correspondingly inserted into the two linear bearings 26. This design helps to improve the smoothness of the sliding support 2. Preferably, the mounting plate 24 is provided with a through hole 242, which avoids the guide rods 12 from passing through, so as to make the overall volume of the material handling device more compact and reasonable.

[0037] In summary, the magnetic material handling device using this solution can handle multiple battery cells 5 more conveniently, reliably, and stably, thereby improving the efficiency of battery cell handling. In addition, since the operator's hands do not directly contact the battery cells 5, the risk of scratches on the battery cell 5 casing, deformation from falling, or short circuits caused by manual contact with the battery cells 5 is greatly reduced, ensuring the integrity, safety, reliability, and quality consistency of the battery cells 5.

[0038] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
