Description

Technical Field

[0001] The present application relates to the technical field of battery shaping, and in particular to a battery shaping device. Background Art

[0002] Rechargeable batteries are also called rechargeable batteries or storage batteries. The shapes of rechargeable batteries are mainly divided into square and cylindrical. Square rechargeable batteries are usually packaged in aluminum or steel shells, with simple structures and manufacturing processes including winding and lamination. Cylindrical rechargeable batteries are mainly steel shells, using winding technology, with a high degree of automation and stable product quality.

[0003] In the related technology, during the production of square secondary batteries, the frequent battery clamping and movement, negative pressure formation, etc. will cause the large surface of the battery to sag, affecting the subsequent coating process and reducing the coating yield. At the same time, rework and quality reduction will increase the consumption of manpower and resources, affecting the subsequent battery production efficiency and product quality. Therefore, it is necessary to provide a battery shaping device to solve the above technical problems. Summary of the invention

[0004] The embodiment of the present application provides a battery shaping device to solve the problem of battery surface depression during the battery production process.

[0005] The present application provides a battery shaping device, comprising:

[0006] An adsorption mechanism, the adsorption mechanism comprising a negative pressure box, and an adsorption tube having one end extending into the negative pressure box and connected to the negative pressure box in a sliding and sealing manner, the adsorption tube being provided with a block for preventing the adsorption tube from escaping from the negative pressure box, and a sealing member for opening or closing the adsorption tube being provided in the negative pressure box;

[0007] The shaping mechanism comprises a clamping seat for clamping the battery and a driving member for driving the clamping seat to move closer to or away from the adsorption tube.

[0008] In some embodiments, there are multiple adsorption tubes, and the multiple adsorption tubes are distributed in an array.

[0009] In some embodiments, the adsorption tube is a hard straight tube, and one end of the hard straight tube away from the negative pressure box is fixedly connected to a suction cup connected to the hard straight tube.

[0010] In some embodiments, the sealing member is an inner wall of the negative pressure box or a platform fixed inside the negative pressure box.

[0011] In some embodiments, the platform includes a connecting seat fixedly connected to the inner wall of the negative pressure box, and a sealing baffle fixedly connected to the connecting seat, and the sealing baffle is made of hard plastic.

[0012] In some embodiments, a limiting block located outside the negative pressure box is provided on the adsorption tube. When the limiting block abuts against the negative pressure box, one end of the adsorption tube contacts the sealing member and is sealed by the sealing member.

[0013] In some embodiments, a fixing plate is provided on the side wall of the negative pressure box, and the adsorption tube passes through the fixing plate and is slidably connected to the fixing plate.

[0014] In some embodiments, the clamping seat includes a vertical plate connected to the driving member, and two transverse plates symmetrically arranged at both ends of the vertical plate, and the two transverse plates are each provided with a clamping block for transversely clamping the battery.

[0015] In some embodiments, the shaping mechanism further includes a guide member connected to the negative pressure box, and the guide member is used to guide the clamping seat to move in a straight line.

[0016] In some embodiments, the guide member is a linear guide rail, which includes a slide rail fixedly connected to the negative pressure box, and a slider slidably connected to the slide rail and fixedly connected to the clamping seat.

[0017] The beneficial effects of the technical solution provided by this application include:

[0018] An embodiment of the present application provides a battery shaping device, including an adsorption mechanism and a shaping mechanism. Since the adsorption mechanism includes a negative pressure box and an adsorption tube with one end extending into the negative pressure box and slidingly and sealingly connected to the negative pressure box, a block is provided on the adsorption tube to prevent the adsorption tube from detaching from the negative pressure box, and a closing member is provided in the negative pressure box for opening or closing the adsorption tube; the shaping mechanism includes a clamping seat for clamping the battery, and a driving member for driving the clamping seat to move closer to or away from the adsorption tube.

[0019] Therefore, after the concave surface of the battery approaches and contacts the adsorption tube, the adsorption tube can be sucked tightly onto the concave surface of the battery by drawing negative pressure on the negative pressure box and the adsorption tube. When the battery is away from the negative pressure box, the block on the adsorption tube is used to abut the negative pressure box to provide a reaction force, so that the adsorption tube pulls the concave surface of the battery to pull and correct the concave surface of the battery.

[0020] Also, because the travel distances of the adsorption tube driven by the concave part and the flat part of the battery surface are different, when the flat part of the battery surface drives the adsorption tube to abut and seal with the sealing part, the distance driven by the concave part of the battery surface to move the adsorption tube will not cause the adsorption tube to be closed by the sealing part. Therefore, when negative pressure is drawn to the negative pressure box, the adsorption tube corresponding to the concave area will be sucked tightly onto the battery surface, so that when the battery is away from the negative pressure box, only the concave part of the battery surface will be pulled and corrected.

[0021] That is, the present application can utilize the stroke difference of the adsorption tube caused by the concave and flat parts of the battery surface to automatically identify the concave parts on the battery surface, and adsorb the concave parts on the battery surface, and at the same time cooperate with the shaping mechanism to pull the concave parts on the battery surface, thereby achieving correction of the concave parts on the battery surface, thereby solving the problem of battery surface concave parts during the battery production process.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a battery shaping device to solve the problem of battery surface depression during the battery production process.

[0031] See also Figures 1 to 4 As shown, the embodiment of the present application provides a battery shaping device, comprising:

[0032] The adsorption mechanism includes a negative pressure box 1, and an adsorption tube 2 with one end extending into the negative pressure box 1 and slidably and sealedly connected to the negative pressure box 1, a stopper 3 is provided on the adsorption tube 2 to prevent the adsorption tube 2 from being separated from the negative pressure box 1, and a sealing member 4 is provided in the negative pressure box 1 to open or close the adsorption tube 2;

[0033] The shaping mechanism includes a clamping seat 5 for clamping the battery, and a driving member 6 for driving the clamping seat 5 to move closer to or away from the adsorption tube 2.

[0034] The battery shaping device of the embodiment of the present application is provided with an adsorption mechanism and a shaping mechanism, the adsorption mechanism includes a negative pressure box 1 and an adsorption tube 2, one end of the adsorption tube 2 extends into the negative pressure box 1 and is slidably and sealingly connected to the negative pressure box 1, and at the same time, the adsorption tube 2 is also fixedly connected to a block 3 located in the negative pressure box 1, a closing member 4 is provided in the negative pressure box 1, and the shaping mechanism includes a clamping seat 5 and a driving member 6.

[0035] Therefore, when the driving member 6 drives the clamping seat 5 to move toward the adsorption tube 2, the recessed surface of the battery on the clamping seat 5 can be made to contact with the adsorption tube 2, while the closing member 4 does not contact with the adsorption tube 2, and then by drawing negative pressure into the negative pressure box 1, the adsorption tube 2 is drawn with negative pressure to be sucked tightly onto the recessed surface of the battery, and then the driving member 6 drives the clamping seat 5 and the battery away from the negative pressure box 1, and the block 3 on the adsorption tube 2 is used to abut against the negative pressure box 1 to provide a reaction force, so that the adsorption tube 2 pulls the recessed surface of the battery to pull and correct the recessed surface of the battery.

[0036] Exemplarily, the closing member 4 is a platform fixed in the negative pressure box 1, the side of the platform facing the adsorption tube 2 is a plane, the negative pressure box 1 is pumped with negative pressure by an external negative pressure pump 10, the driving member 6 adopts a pneumatic push rod and is driven by an external air pump 11, the corresponding corrected battery is a square battery, and the battery is provided with a starting position and an end position in the moving direction.

[0037] When the battery moves from the starting position to the end position with the shaping mechanism, if the mouth of the adsorption tube 2 contacts the sealing member 4 and is sealed, the battery surface in contact with the adsorption tube 2 is a flat surface. Since the mouth of the adsorption tube 2 is sealed, when the negative pressure is drawn in the negative pressure box 1, the negative pressure will not be drawn in the adsorption tube 2, and the adsorption tube 2 will not be sucked tightly on the battery surface. Therefore, when the battery returns to the starting position with the shaping mechanism, the adsorption tube 2 will not move with the battery and pull the battery surface.

[0038] When the battery moves to the final position with the shaping mechanism, if the mouth of the adsorption tube 2 is not in contact with the closure 4, the surface of the battery in contact with the adsorption tube 2 is a concave surface. Since the mouth of the adsorption tube 2 is not closed, when negative pressure is drawn in the negative pressure box 1, negative pressure will be drawn into the adsorption tube 2, so that the adsorption tube 2 is sucked tightly on the concave surface of the battery. Therefore, when the battery returns with the shaping mechanism, the adsorption tube 2 will move with the battery. After the stopper 3 on the adsorption tube 2 contacts the negative pressure box 1, the adsorption tube 2 stops moving and the battery continues to move, so that the adsorption tube 2 pulls the concave surface of the battery, thereby pulling and correcting the concave surface of the battery.

[0039] It should be noted that, since the driving member 6 of the shaping mechanism can drive the battery on the clamping seat 5 to approach the adsorption tube 2, the battery can drive the adsorption tube 2 to approach the sealing member 4, and the adsorption tube 2 can close the tube opening of the adsorption tube 2 by contacting the sealing member 4. In addition, under the premise that the battery moves a certain distance, the flat surface of the battery contacts the adsorption tube 2 earlier than the concave surface, and the distance driven by the flat surface of the battery to move the adsorption tube 2 is greater than the distance driven by the concave surface of the battery to move the adsorption tube 2.

[0040] If the distance that the adsorption tube 2 moves when the battery surface is flat is just enough to make the adsorption tube 2 be closed by the sealing member 4, then the distance that the adsorption tube 2 moves when the battery surface is concave will not make the adsorption tube 2 be closed by the sealing member 4. Only when the adsorption tube 2 is not closed by the sealing member 4, the adsorption tube 2 will be sucked tightly on the battery surface when the negative pressure box 1 is pumped with negative pressure, and then when the battery is returned, the battery surface can be pulled and corrected by the adsorption tube 2. Therefore, the starting position and the end position of the battery can be set, and the concave part of the battery surface can be automatically identified by whether the sealing member 4 closes the adsorption tube 2, and only the concave part of the battery surface can be pulled and corrected.

[0041] That is, the adsorption mechanism of the present application can automatically identify the depressions on the battery surface and realize the adsorption of the depressions on the battery surface. At the same time, it can cooperate with the shaping mechanism to pull the depressions on the battery surface, and then realize the correction of the depressions on the battery surface, thereby solving the problem of battery surface depressions during the battery production process.

[0042] In some alternative embodiments: See Figures 1 to 4As shown, an embodiment of the present application provides a battery shaping device, which has a plurality of adsorption tubes 2, and the plurality of adsorption tubes 2 are distributed in an array.

[0043] There are multiple adsorption tubes 2 in the embodiment of the present application, and the multiple adsorption tubes 2 are distributed in an array. The array distribution area of ​​the multiple adsorption tubes 2 can basically cover the large surface of the square battery. When repairing the battery, the battery is clamped and fixed on the clamping seat 5 and the large surface of the battery is exposed. The clamping seat 5 is driven by the driving member 6 to move toward the adsorption tube 2, so that the large surface of the battery contacts the multiple adsorption tubes 2, and the flat surface of the battery drives the adsorption tube 2 to move and makes the adsorption tube 2 abut against the closing member 4 and be closed, thereby limiting the battery from continuing to approach the negative pressure tube.

[0044] Since the concave part of the battery surface contacts the adsorption tube 2 later than the flat part, the distance driven by the concave part of the battery surface to move the adsorption tube 2 will not cause the adsorption tube 2 to be closed by the sealing member 4. Therefore, when negative pressure is drawn to the negative pressure box 1, the adsorption tube 2 corresponding to the concave area will be sucked tightly onto the battery surface. Then, when the battery returns with the clamping seat 5, the battery can drive this part of the adsorption tube 2 to move, and the block 3 on the adsorption tube 2 is used to abut the negative pressure box 1 to provide a reaction force, so that this part of the adsorption tube 2 can pull the concave surface of the battery to pull and correct the concave surface of the battery.

[0045] It should be noted that, since the adsorption tube 2 driven by the flat surface of the battery is closed by the sealing member 4, when the negative pressure box 1 is pumped with negative pressure, the adsorption tube 2 in this part will not be pumped with negative pressure, so when the battery returns with the shaping mechanism, the adsorption tube 2 will not move with the battery and pull the battery surface. That is, this embodiment can use the stroke difference of the adsorption tube 2 caused by the concave part and the flat part of the battery surface to automatically identify the concave part of the battery surface, and realize the pulling correction of only the concave part of the battery surface.

[0046] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, in which the adsorption tube 2 of the battery shaping device is a hard straight tube, and one end of the hard straight tube away from the negative pressure box 1 is fixedly connected with a suction cup 21 connected to the hard straight tube.

[0047] The adsorption tube 2 of the embodiment of the present application is a hard straight tube, which can better transmit the pulling force when correcting the depression on the battery surface. Specifically, the hard straight tube can be made of metal or non-metallic materials under the premise of ensuring tensile strength, which is not specifically limited here. Furthermore, in order to facilitate the hard straight tube to suck the battery surface tightly, the end of the hard straight tube away from the negative pressure box 1 is fixedly connected with a suction cup 21 connected to the hard straight tube. When the suction cup 21 contacts the battery surface, negative pressure is drawn on the hard straight tube, so that the suction cup 21 can be sucked tightly on the battery surface. Exemplarily, the suction cup 21 can be made of rubber material.

[0048] It should be noted that the purpose of installing the suction cup 21 in the present embodiment is to enable the tube mouth of the adsorption tube 2 to better contact the battery surface, so that when negative pressure is drawn in the adsorption tube 2, the adsorption tube 2 is sucked tightly on the battery surface. At the same time, when negative pressure is not drawn in the adsorption tube 2, the adsorption tube 2 will not be sucked tightly on the battery surface, that is, in this case, when the battery is away from the negative pressure box 1, the adsorption tube 2 will not pull the battery surface. Based on this, technical personnel in this field can adaptively adjust the size, shape and material of the suction cup 21 according to the usage scenario and test conditions.

[0049] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, in which the closing member 4 of the battery shaping device is the inner wall of the negative pressure box 1 or a platform fixed inside the negative pressure box 1 .

[0050] The sealing member 4 of the embodiment of the present application is the inner wall of the negative pressure box 1, and the inner wall of the negative pressure box 1 is the wall surface on one side facing the tube mouth of the adsorption tube 2. By reasonably designing the size of the negative pressure box 1 and the sliding stroke of the adsorption tube 2, it is possible to use the inner wall of the negative pressure box 1 to contact and seal the tube mouth of the adsorption tube 2. Specifically, when the adsorption tube 2 approaches and abuts against the inner wall of the negative pressure box 1, the tube mouth of the adsorption tube 2 can be sealed by the inner wall of the negative pressure box 1. When there is a gap between the tube mouth of the adsorption tube 2 and the inner wall of the negative pressure box 1, the adsorption tube 2 remains connected to the negative pressure box 1 and can be pumped with negative pressure together with the negative pressure box 1. In some other embodiments, the sealing member 4 can be a platform fixed in the negative pressure box 1, and the surface of the platform is used to contact and seal the tube mouth of the adsorption tube 2 to prevent the adsorption tube 2 from hitting the inner wall of the negative pressure box 1.

[0051] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, the platform of which includes a connecting seat 41 fixedly connected to the inner wall of the negative pressure box 1, and a sealing baffle 42 fixedly connected to the connecting seat 41, and the sealing baffle 42 is made of hard plastic.

[0052] The platform of the embodiment of the present application includes a connecting seat 41 fixedly connected to the inner wall of the negative pressure box 1, and a sealing baffle 42 fixedly connected to the connecting seat 41. The sealing baffle 42 can be set according to the surface shape of the battery to be shaped. If it is the large surface of a square battery to be shaped, the sealing baffle 42 can be set as a flat plate. If it is the cylindrical surface of a cylindrical battery to be shaped, the sealing baffle 42 can be set as an arc plate consistent with the radius of the cylindrical surface.

[0053] Furthermore, the sealing baffle 42 in this embodiment is made of hard plastic, which has good viscoelastic recovery properties and a good ability to return to its original state after being subjected to external force. In the process where the tube mouth of the adsorption tube 2 repeatedly contacts and squeezes the surface of the sealing baffle 42, the permanent damage caused by repeated collisions of the adsorption tube 2 can be reduced.

[0054] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, in which an adsorption tube 2 is provided with a limit block 7 located outside the negative pressure box 1. When the limit block 7 abuts against the negative pressure box 1, one end of the adsorption tube 2 contacts the closure 4 and is closed by the closure 4.

[0055] The adsorption tube 2 of the embodiment of the present application is provided with a limit block 7 located outside the negative pressure box 1, and the limit block 7 can limit the movement of the adsorption tube 2 into the negative pressure box 1. When the upper limit block 7 on the adsorption tube 2 abuts against the negative pressure box 1, one end of the adsorption tube 2 contacts the closure 4 and is closed by the closure 4. Therefore, it can be avoided that the adsorption tube 2 is excessively squeezed on the surface of the closure 4 when moving with the battery.

[0056] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, in which a fixing plate 8 is provided on the side wall of the negative pressure box 1 of the battery shaping device, and the adsorption tube 2 passes through the fixing plate 8 and is slidably connected to the fixing plate 8.

[0057] A fixing plate 8 is fixed on the side wall of the negative pressure box 1 in the embodiment of the present application. The fixing plate 8 can increase the strength of the side wall of the negative pressure box 1 and facilitate the penetration of the adsorption tube 2. When the thickness of the side wall of the negative pressure box 1 is small, the fixing plate 8 can be installed to facilitate the sliding and guiding of the adsorption tube 2 after installation.

[0058] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, wherein a clamping seat 5 of the battery shaping device includes a vertical plate 51 connected to a driving member 6, and two transverse plates 52 symmetrically arranged at both ends of the vertical plate 51, and both transverse plates 52 are provided with clamping blocks 53 for transversely clamping the battery.

[0059] The clamping seat 5 of the embodiment of the present application includes a vertical plate 51 fixedly connected to the driving member 6, and the two ends of the vertical plate 51 are fixedly connected to the horizontal plate 52, and the horizontal plate 52 is equipped with a clamping block 53 for clamping the battery on the vertical plate 51. Exemplarily, the clamping block 53 can be slidably connected to the horizontal plate 52 and connected to the vertical plate 51 by bolts, thereby achieving the pulling and clamping of the battery on the vertical plate 51. Alternatively, a screw rod is installed on the horizontal plate 52 to drive the clamping block 53, so that the battery is pressed against the vertical plate 51 by the clamping block 53.

[0060] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, wherein the shaping mechanism of the battery shaping device further includes a guide member 9 connected to the negative pressure box 1, and the guide member 9 is used to guide the clamping seat 5 to move in a straight line.

[0061] The shaping mechanism of the embodiment of the present application further includes a guide member 9 connected to the negative pressure box 1, and the guide member 9 can guide the clamping seat 5 during the movement of the battery to ensure that the battery moves in a straight line to approach or move away from the negative pressure box 1. Exemplarily, the guide member 9 can be a linear guide rail or a limit slideway matched with the clamping seat 5.

[0062] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a battery shaping device, in which the guide member 9 of the battery shaping device is a linear guide rail, which includes a slide rail fixedly connected to the negative pressure box 1, and a slider slidably connected to the slide rail and fixedly connected to the clamping seat 5.

[0063] The guide member 9 of the embodiment of the present application is a linear guide rail, the slide rail of the linear guide rail is fixedly connected to the negative pressure box 1, and the slider on the slide rail is fixedly connected to the transverse plate 52 on the clamping seat 5, thereby constraining the clamping seat 5 to move along the slide rail. For example, to ensure the reliability of the guide, the linear guide rails can be installed at both the upper and lower ends of the clamping seat 5.
