Description

Technical Field

[0001] The present disclosure relates to a mold-type secondary battery pouch cell terrace folding device, and more particularly to a mold-type secondary battery pouch cell terrace folding device, which can adjust a roller spacing and a press unit spacing by replacing a stopper of an edge of a secondary battery pouch cell used for folding and sealing. Background Art

[0002] A pouch-type secondary battery includes an electrode assembly, a pouch case housing the electrode assembly, and an electrode tab extending from the electrode assembly and protruding to the outside. The pouch case includes a case body providing a space in which the electrode assembly can be accommodated and a case cover covering the case body, and the edges of the case body and the case cover are usually bonded to each other by hot pressing.

[0003] After the edge of the pouch-type secondary battery is sealed, the sealed edge is folded. The purpose of folding the edge of the pouch-type secondary battery is to prevent corrosion of the sealed portion and to improve the rigidity of the pouch. In addition, folding the edge of the secondary battery can also reduce the overall size of the secondary battery and minimize the space occupied by the secondary battery.

[0004] Since the folding process performed in the sealing part of the pouch type secondary battery is to fold the pouch sealing part by passing the sealing part through a plurality of rollers mounted on the upper plate and the lower plate of the folding part, it is very important to adjust the folding roller spacing suitable for the thickness of the pouch sealing part. However, the current folding roller spacing adjustment adopts a manual setting method by the operator, so it is impossible to adjust an accurate value, and its accuracy depends on the ability of the operator.

[0051] The present disclosure can be modified in various ways and can have many embodiments, so specific embodiments are shown in the drawings and described in detail. However, this does not mean that the present disclosure is limited to specific embodiments, but should be understood to include all modifications within the concept and technical scope of the present disclosure.

[0052] Unless otherwise defined, all terms including technical or scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which the present disclosure belongs.

[0053] Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant art, and should not be interpreted as an ideal or overly formal meaning unless expressly defined in this application.

[0054] The present disclosure will be described in detail below with reference to the accompanying drawings. However, this is merely exemplary, and the present disclosure is not limited to the specific embodiments exemplarily described.

[0055] Figure 1 1 is a front view of a secondary battery bag cell platform folding device according to an embodiment of the present disclosure. Figure 1 , a secondary battery bag cell platform folding device, the secondary battery bag cell platform is folded when passing between an upper roller 111 and a lower roller 121, the secondary battery bag cell platform folding device comprising: an upper mounting seat 110, the upper roller 111 is arranged on the upper mounting seat 110 along the length direction; a lower mounting seat 120, the lower roller 121 is arranged on the lower mounting seat 120 along the length direction; a support frame 30, which is vertically arranged on the upper surface of a lower plate 20 and penetrates the upper mounting seat 110 to enable the upper mounting seat 110 to move up and down; and a block B, which is arranged between the upper mounting seat 110 and the lower mounting seat 120 to adjust the distance between the upper roller 111 and the lower roller 121.

[0056] The lower plate 20 is disposed such that its lower surface contacts the ground or a table. The support frame 30 is vertically disposed on the upper surface of the lower plate 20. The upper plate 10 is disposed on the upper end of the support frame 30 and is horizontal to the lower plate 20.

[0057] The lower mount 120 is coupled to the upper surface of the lower plate 20 to fix the position. The lower mount 120 is disposed to be penetrated by the support frame 30. A plurality of rollers are disposed at the front of the lower mount 120 along the length direction.

[0058] The upper mounting seat 110 is disposed between the upper plate 10 and the lower mounting seat 120. In addition, the upper mounting seat 110 is penetrated by the support frame 30 and moves along the support frame 30 in the height direction, and its movement in the length direction and the width direction is restricted. A plurality of upper rollers 111 are disposed in the length direction at the front of the upper mounting seat 110. The upper rollers 111 and the lower rollers 121 are disposed in pairs. The shapes and positions of the lower rollers 121 and the upper rollers 111 are designed as a terrace for folding the secondary battery, and the shapes and positions of the lower rollers 121 and the upper rollers 111 may be changed according to the folding method.

[0059] The upper roller 111 and the lower roller 121 are disposed to be spaced apart so that when the lower surface of the upper mount 110 and the upper surface of the lower mount 120 are in contact, the upper roller 111 and the lower roller 121 are not in contact or damaged.

[0060] When the platform portion of the secondary battery is folded, the upper mount 110 may be fixed in position by a load to maintain quality. At this time, an additional weight may be placed on the upper end of the upper mount 110 as needed.

[0061] The upper mounting seat 110 further includes a connection portion 130, which is connected to an external power device to move the upper mounting seat 110 up and down. The connection portion 130 is formed on the upper surface of the upper mounting seat 110. The connection portion 130 is connected to the cylinder 400 or a motor or the like through a connecting member to make the upper mounting seat 110 rise and fall. In addition, the connection portion 130 can be formed in the form of a handle for manual operation.

[0062] The secondary battery bag cell platform folding device further includes a stopper 200, which is disposed on the guide member 300 and disposed between the upper mounting seat 110 and the upper plate 10. The stopper 200 is configured to limit the rising height of the upper mounting seat 110, and can prevent the upper mounting seat 110 from being directly contacted with the upper plate 10 and damaged when rising.

[0063] Figure 2 is a front view of an embodiment with a block inserted. Figure 2 The upper plate 10 and the lower plate 20 are spaced apart in the height direction, one or more guide members 300 are disposed between the upper plate 10 and the lower plate 20 , and the upper plate 10 and the lower plate 20 are connected by the guide members 300 .

[0064] The lower mount 120 is coupled to the upper surface of the lower plate 20. The upper mount 110 is provided on the upper side of the lower mount 120 to move up and down along the guide 300. The lower mount 120 is coupled to the lower plate 20 to fix the position. The upper mount 110 receives an external force through the connection part 130 formed at the upper end thereof and rises.

[0065] A connection portion 130 connected to an external device is formed at the upper end of the upper mount 110. The upper mount 110 receives an external force through the connection portion 130 and rises to be spaced apart from the lower mount 120. A block B having a predetermined height is provided between the upper mount 110 and the lower mount 120. The upper mount 110 and the lower mount 120 are spaced apart by a height corresponding to the block B, while the lower roller 121 and the upper roller 111 are spaced apart by a height corresponding to the block B.

[0066] At this time, the upper mount 110 is raised by the external device. A stopper 200 may be provided between the upper plate 10 and the upper mount 110 to prevent the upper mount 110 from excessively rising. The stopper 200 is provided on the guide member 300. In order to prevent the rising upper mount 110 from colliding with the upper plate 10 and being damaged, the upper mount 110 is made of an elastic material such as rubber to absorb the impact.

[0067] After the block B is inserted, the raised upper mount 110 descends and contacts the upper surface of the block B. The upper mount 110 descends by its own weight or by the force of an external device. The lowered upper mount 110 is fixed in position by its own weight or by the continuous force of an external device. In addition, the position may be fixed by a coupling member (not shown) coupling the upper mount 110 and the lower mount 120. The coupling member is provided at the rear or side of the upper mount 110 and the lower mount 120 so as not to hinder folding.

[0068] The block B can be formed into a rectangular parallelepiped, a cylinder with horizontal upper and lower surfaces, etc., and the position is fixed by one or more of the weight of the upper mounting seat 110, the pressure of external equipment, and the binding force of the coupling parts. In addition, the shape of the block B can be changed according to convenience. For example, one or more blocks B are formed into a U-shape with an insertion portion in the center, and are configured to contact the outer surface of the guide member 300 exposed between the upper mounting seat 110 and the lower mounting seat 120. The insertion portion of the block B corresponds to the cross-sectional shape of the guide member 300. The advantage is that the block B can be easily installed and disassembled by the insertion portion, and the guide member 300 serves as a reference for the position of the block B, which is convenient for operation instructions.

[0069] In addition, at least one of the blocks may be spaced apart from the guide and disposed on the upper surface of the lower mounting seat. The blocks may be fixed by the load of the upper mounting seat.

[0070] In another example of the shape of the block B, a concave-convex is formed on at least one of the upper surface of the block B that contacts the upper mounting seat 110 and the lower surface of the block B that contacts the lower mounting seat 120. The upper mounting seat 110 and the lower mounting seat 120 have shapes corresponding to the concave-convex of the block B. The block B is formed into a rectangular parallelepiped with a certain height, a cylinder with a horizontal upper surface and a horizontal lower surface, etc., and the convex part formed on the upper surface of the block B is combined with the concave part corresponding to the convex part on the lower surface of the upper mounting seat 110. In this way, the position of the block B can be fixed, so that the distance between the upper mounting seat 110 and the lower mounting seat 120 and the distance between the upper roller 111 and the lower roller 121 are maintained for a long time.

[0071] A fixing member may be further included, the fixing member fixing the block B and the upper mounting seat 110 or the block B and the lower mounting seat 120 to prevent the set block B from being separated to the outside. The fixing member is coupled to the outer side surface of the block B and the outer side surface of the upper mounting seat 110 or the lower mounting seat 120 to prevent the block B from being separated.

[0072] Figure 3 It is a schematic diagram of the use of the present disclosure. Figure 3 The present disclosure can be used as a multi-purpose pressing device by using the upper mounting seat 110 and the lower mounting seat 120 from which the upper roller 111 and the lower roller 121 are removed. The height of the pressed shape is limited by the block B disposed between the upper mounting seat 110 and the lower mounting seat 120. The shape, insertion and fixing method of the block B are the same as those of the above-mentioned folding device example.

[0073] The upper mounting seat 110 is connected to an external device through a connection portion 130 formed at the upper end thereof, and receives the force required for ascending and descending from the external device. An example of the external device is a cylinder 400 having a piston 410. The cylinder is controlled so that the driving component pressurizes the connection portion. The pressurizing force depends on the performance of the external device including the cylinder.

[0074] The upper mount 110 and the lower mount 120 may be interchangeable, and the shape of the surface of the pressed material may be changed according to the shapes of the lower surface of the upper mount 110 and the upper surface of the lower mount 120 .

[0075] The embodiments of the present invention are further described below with reference to other specific embodiments. The embodiments are only examples of the present invention and do not limit the scope of the appended claims. It is obvious to those skilled in the art that various changes and modifications can be made to the embodiments within the scope of the present invention and the technical concept, and these changes and modifications belong to the scope of the appended claims.

[0076] Figure 4 2 is a front view of another embodiment. Figure 4, a secondary battery bag cell platform folding device, the secondary battery bag cell platform is folded when passing between an upper roller 111 and a lower roller 121, the secondary battery bag cell platform folding device comprising: a lower plate 20, coupled to a lower mounting seat 120 provided with the lower roller 121 along the length direction; an upper plate 10, spaced apart from the lower plate 20 in the height direction by a support frame 30 vertically provided on the lower plate 20; a guide member 300, which is provided through the upper plate 10, and one end of the guide member 300 is coupled to a connecting portion 130 of an upper mounting seat 110 provided with an upper roller 111, and the other end is coupled to a head 310 in contact with the upper surface of the upper plate 10; and a block B, which is provided between the upper surface of the upper plate 10 and the lower surface of the head 310 to adjust the spacing between the upper roller 111 and the lower roller 121.

[0077] The upper plate 10 and the lower plate 20 are spaced apart in the height direction. One end of the support frame 30 is coupled to the upper plate 10 and the other end is coupled to the lower plate 20. A lower mounting seat 120 having a lower roller 121 is coupled to the upper surface of the lower plate 20.

[0078] The upper plate 10 is formed with a plurality of through holes, and guide members 300 corresponding to the diameter of the through holes are inserted into the through holes. The upper end of the guide member 300 is coupled to a head 310 having a diameter greater than the diameter of the through hole of the upper plate 10. The lower surface of the head 310 is disposed to contact the upper surface of the upper plate 10. The lower end of the guide member 300 is coupled to a connection portion 130 disposed between the lower mount 120 and the upper plate 10. The lower surface of the connection portion 130 is coupled to the upper mount 110 having the upper roller 111.

[0079] The upper surface of the connection part 130 protrudes to form a protrusion 131. The protrusion 131 is connected to an external device provided at the upper end of the upper plate 10 to receive a force in the ascending direction. The cylinder 400 as an example of the external device includes a piston 410 and a driving member 420 coupled to the end of the piston 410. The protrusion 131 is formed in a handle shape in which a space in which the driving member 420 can be provided is formed, and a hole is formed on the upper surface of the protrusion 131, and the diameter of the hole is smaller than the driving member 420 and larger than or corresponding to the diameter of the piston 410.

[0080] The piston 410 penetrates the upper plate 10 and is inserted into the hole of the protrusion 131. The end of the piston 410 is combined with a driving member 420, which is larger than the diameter of the hole of the protrusion 131. When the piston 410 rises, the driving member 420 contacts the upper surface of the inner part of the protrusion 131 and transmits the ascending force to the connection part 130. When the piston 410 descends, the driving member 420 is spaced apart from the upper surface of the inner part of the protrusion 131.

[0081] The upper mounting seat 110, the upper roller 111, the guide 300 and the head 310 directly or indirectly coupled to the connecting portion 130 are raised by the operation of the cylinder 400. At this time, the horizontal movement of the connecting portion 130 is restricted by the plurality of guides 300, and the connecting portion 130 moves in the height direction.

[0082] By rising, the block B is disposed in the spaced-apart space between the head 310 and the upper plate 10. The block B may be shaped to contact or surround the guide 300 as described above, and may be deformed in various shapes.

[0083] The upper plate 10 includes a sensor 500 for measuring the height of the upper roller, upper mount, and connection 130. If a jam occurs between the rollers during operation, the height of the upper roller, upper mount, and connection changes. The sensor senses the height change and senses the jam during operation. This has the advantage that the operation can be interrupted by sensing the jam, preventing major problems in advance.

[0084] In addition, the sensor 500 can prevent the connection part 130 and the upper plate 10 from being damaged due to excessive lifting of the connection part 130. In addition, the sensor 500 can measure the thickness of the block B, whether the block is set, and the interval between the upper roller 111 and the lower roller 121 by measuring the position of the connection part 130.

[0085] In addition, the block is formed with at least one sensing hole of different shape, number and position according to the thickness, and the sensor is set on the upper plate and identifies the sensing hole formed on the block to sense the thickness of the block and whether the block is set. For example, if a sensing hole is formed per 1t on the block, the sensor can identify the thickness of the installed block by the number of identified sensing holes. As another example, the sensing holes are formed into a circle, a quadrilateral, a triangle, etc. according to the thickness of the block, and the sensor can identify the thickness of the installed block by the shape of the sensing holes. As yet another example, the positions of the sensing holes of the block are different from each other based on the center of the block according to the thickness, and the sensor can identify the thickness of the block according to the position of the sensing hole.

[0086] Figure 5 is a side view of another embodiment. Figure 5 , the upper plate 10 and the lower plate 20 are spaced apart in the height direction by the support frame 30, and the lower mounting seat 120 and the lower roller 121 are provided on the upper surface of the lower plate.

[0087] A plurality of guide members 300 are arranged through the upper plate 10 in the height direction. A head 310 is formed at the upper end of each guide member 300, and the lower end of the guide member 300 is coupled to the connection part 130. The connection part 130 is coupled to the plurality of guide members 300, and a groove is formed on its side to be spaced apart from the support frame 30.

[0088] An upper mounting seat 110 and an upper roller 111 are provided at the lower end of the connecting portion 130. A cylinder 400 running in the height direction is provided on the upper surface of the upper plate 10, and the connecting portion 130 is moved in the height direction by the cylinder 400, and a block B is provided between the head 310 and the upper plate 10 to adjust the spacing between the upper roller 111 and the lower roller 121.

[0089] The upper roller 111 is raised by the cylinder 400, and when the cylinder 400 is lowered, the upper roller 111 is lowered by its own weight. In addition, the connection part 130 is lowered by the tension of the spring provided on the guide 300 and provided between the upper plate 10 and the connection part 130.

[0090] The descending height of the connection part 130 descending by its own weight or the tension of the spring is limited by the head 310 and the block B. More specifically, the diameter of the head 310 is larger than the diameter of the through hole of the upper plate 10, and the head 310 is arranged to contact the upper surface of the upper plate 10 to limit the descending height of the connection part 130, the upper mounting seat 110, and the upper roller 111. At this time, the descending height is reduced by the height equivalent to the block B, and the upper roller 111 and the lower roller 121 are further spaced apart by the height equivalent to the block B.

[0091] The diameters of the upper roller 111 and the lower roller 121 may be formed in various diameters. The diameters of the upper roller 111 and the lower roller 121 may be greater than the heights of the upper mounting seat 110 and the lower mounting seat 120, so that the platform portion having a larger width may be folded.

[0092] Figures 6 to 9 Schematic diagram showing the driving sequence of the secondary battery bag cell platform folding device. For ease of explanation, the upper mounting seat, the lower mounting seat, the upper roller and the lower roller are omitted, and the description will be based on the position of the connecting portion. The spacing between the upper roller and the lower roller changes according to the change of the spacing between the connecting portion and the lower plate. Figure 6 This is the initial stage. The head 310 and the upper plate 10 are set to be in contact. The connecting part 130 and the lower plate 20 are closest. The connecting part is lowered by the load of the connecting part and the spring provided on the guide member 300.

[0093] Figure 7 The connecting part 130 is connected to the cylinder 400 formed at the upper end of the upper plate, and the connecting part 130 is raised by the operation of the cylinder. Specifically, a protrusion 131 is formed at the upper end of the connecting part, and a driving component 420 disposed inside the protrusion is connected to the cylinder. By the operation of the cylinder, the driving component, the protrusion and the connecting part are raised together.

[0094] Figure 8It is the block setting stage. The connecting part 130 rises by the cylinder, and the guide member coupled to the connecting part also rises together. The head 310 formed at the upper end of the guide member is spaced apart from the upper plate 10. The block B is set in the separated space to adjust the descending height of the connecting part. The block can be set to contact or surround the guide member exposed between the head and the upper plate.

[0095] Fig. 9 The driving part is lowered by the lowering operation of the cylinder 400, and the guide and the connecting part 130 are lowered. At this time, the head 310 is also lowered and contacts the upper surface of the block B. The spacing between the connecting part and the lower plate is further spaced by the height of the block. At this time, the connecting part is fixed in position by the continuous descending force applied by the spring provided on the guide.

[0096] The above contents are merely examples of applying the technology of the present disclosure, and other configurations may also be included without departing from the scope of the present invention.
