Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of batteries, in particular to a turnover riveting die and a battery production line. BACKGROUND

[0002] In the production and manufacturing process of the battery pack shell box, the turnover riveting nut needs to be installed on the battery pack shell box through the turnover riveting machine, and the installation quality directly affects the structural stability, use safety and air tightness of the battery pack shell box.

[0003] In the related art, the turnover riveting machine has poor turnover riveting consistency, and the nuts after turnover riveting often appear to be skewed. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems, the present application provides a turnover riveting die and a battery production line, which can solve the problem of poor turnover riveting consistency of the existing turnover riveting machine in use, and the nuts after turnover riveting often appear to be skewed.

[0005] To solve the above technical problems, in a first aspect, the present application provides a turnover riveting die, comprising:

[0006] A first die has a working surface and a mounting surface;

[0007] A bearing table is provided on the working surface, and the bearing table is provided with a positioning member and a placing groove, the positioning member is configured to position the shell box, and the placing groove is configured to place the turnover riveting nut;

[0008] A supporting plate is provided on the mounting surface and is configured to support the shell box to be turnover riveted;

[0009] A second die is provided with a clearance hole, and the clearance hole cooperates with the positioning member.

[0010] In the technical scheme of the present application, the positioning member on the bearing table cooperates with the hole on the shell box, so that the shell box can be accurately positioned, and the stability of the shell box position when manually held can be ensured. At the same time, when the shell box is supported on the supporting plate and tightly attached to the surface of the bearing table, the second die moves towards the first die until the second die is pressed on the shell box, so that the shell box can be pressed and limited, preventing it from moving during turnover riveting, and ensuring that the shell box is always in a parallel and stable state. In this way, the whole process does not need to manually hold the shell box, reducing the influence of the operation force and the difference in hand stability of the workers on the turnover riveting operation, improving the consistency of the turnover riveting, and avoiding the problem of skewed nuts after turnover riveting.

[0011] In some embodiments, the rivet turning die further comprises a pressure plate, the pressure plate is arranged on the second die, and the avoiding hole is arranged on one side of the pressure plate facing the first die.

[0012] In some embodiments, one side of the bearing table facing the pressure plate is fitted with the side of the shell box to be rivet turned.

[0013] Since one side of the bearing table facing the pressure plate is fitted with the side of the shell box to be rivet turned, the bearing table can be used to accurately position the shell box to be rivet turned, thereby improving the rivet turning qualification rate.

[0014] In some embodiments, one side of the pressure plate facing the bearing table is provided with a clamping groove, one side of the bearing table facing the pressure plate is provided with a protruding part, and the protruding part is matched with the clamping groove.

[0015] In this way, the pressure plate can be accurately placed on the bearing table to accurately press the shell box on the bearing table.

[0016] In some embodiments, one side of the pressure plate facing the first die is provided with a positioning groove, one side of the first die facing the pressure plate is provided with a first limiting piece, and the first limiting piece is matched with the positioning groove.

[0017] In this way, when the second die moves the pressure plate towards the first die, the pressure plate can be accurately placed on the first die through the cooperation of the positioning groove and the first limiting piece, so as to avoid the deviation of the pressure plate during the pressing process.

[0018] In some embodiments, a plurality of positioning pieces are arranged on the bearing table, a plurality of avoiding holes are arranged on the pressure plate, and the positions of the avoiding holes correspond to the positions of the positioning pieces.

[0019] In this way, the accurate positioning of the shell box can be realized through the cooperation of the plurality of positioning pieces with each hole on the shell box.

[0020] In some embodiments, the rivet turning die further comprises an elastic buffer, and the elastic buffer is arranged between the pressure plate and the second die.

[0021] In this way, the elastic buffer can buffer the instantaneous pressure of the pressure plate on the rivet nut during the pressing process of the pressure plate, so as to avoid rigid collision between the two.

[0022] In some embodiments, the length of the supporting plate is adjustable.

[0023] In this way, the length of the supporting plate can be adjusted according to actual needs to adapt to shell boxes of different sizes.

[0024] In some embodiments, the surface of the tray is provided with a flexible layer. This ensures that when the tray supports the outer casing, the flexible layer on the tray contacts the corresponding outer casing, thereby preventing scratches on the surface of the outer casing.

[0025] In some embodiments, the positioning element is detachably connected to the support platform. This allows for the replacement of the positioning element with one of corresponding dimensions when the model of the housing to be riveted changes, thus enabling the positioning of different housing models.

[0026] In some embodiments, the inner wall of the placement groove is provided with anti-slip texture or elastic padding, configured to prevent the riveting nut from rotating or shifting during the pressing process.

[0027] This prevents the riveting nut from rotating or shifting during the pressing process, thereby improving the accuracy of the riveting nut during pressing.

[0028] In some embodiments, the first mold is provided with through holes. This reduces the weight of the first mold.

[0029] In some embodiments, the first mold includes a bottom surface, the area of ​​which is greater than the area of ​​the working surface, wherein the working surface and the bottom surface are located on opposite sides of the first mold.

[0030] In this way, since the area of ​​the bottom surface is larger than the area of ​​the working surface, the overall first mold is trapezoidal, which improves the stability of the overall first mold with the support of the bottom surface.

[0031] In some embodiments, the riveting mold further includes a second limiting member disposed on the mounting surface;

[0032] The second limiting member can move closer to or further away from the mounting surface. When the outer casing to be riveted is hung on the tray, the second limiting member abuts against the inner wall of the outer casing.

[0033] In this way, the second limiting member abuts against the inner wall of the outer casing, preventing the outer casing from tilting under the support of the tray.

[0034] In some embodiments, the second limiting member includes a plug-in plate, a snap-in block, a slide bar, and a pull plate;

[0035] The first mold is provided with an insertion groove and a sliding cavity. The sliding cavity extends along a first direction. One end of the sliding cavity is connected to the insertion groove, and the other end is connected to the outside.

[0036] The plug plate is disposed in the plug slot, the slide rod is located in the slide cavity, the snap block is slidably connected to the plug plate, one end of the slide rod is connected to the snap block, and the other end is connected to the pull plate. The pull plate is located outside the first mold and is configured to drive the snap block to move relative to the slide cavity along the first direction.

[0037] In this way, by pulling the pull plate relative to the plug-in plate to the preset position, the pull plate abuts against the inner wall of the outer casing supported on the support plate, thus preventing the entire outer casing from tilting.

[0038] In some embodiments, the plug plate has a groove on the side facing the sliding cavity, and the snap-fit ​​block is at least partially located within the groove.

[0039] In some embodiments, the second limiting member further includes a fixing plate and an elastic member. The fixing plate is fixed inside the sliding cavity, and the elastic member is sleeved on the sliding rod. One end of the elastic member abuts against the snap-fit ​​block, and the other end abuts against the fixing plate.

[0040] Secondly, this application proposes a battery production line, including a riveting mold as described in any one of the embodiments of this application.

[0058] In the manufacturing process of battery pack housings for new energy vehicles, the installation of riveting nuts is a critical step, and its installation quality directly affects the structural stability, safety, and airtightness of the battery pack housing.

[0059] Currently, the industry standard for installing riveting nuts on battery pack housings is to use a riveting machine to rivet each nut individually. However, because new energy vehicle battery pack housings are generally large and heavy, two workers are needed to hold the housing in place during the riveting process to complete the riveting operation.

[0060] Due to the obvious drawbacks of manual operation, it is difficult for two workers to ensure that the box remains in a parallel and stable state during the riveting process. Furthermore, the different operating forces and hand stability of different workers can lead to poor riveting consistency, which directly causes the nuts to be crooked after riveting.

[0061] Based on the above considerations, in order to solve the problem of poor riveting consistency and the frequent skewness of riveted nuts when using existing riveting machines, this application proposes a riveting mold. The riveting mold includes a first mold, a support platform, a tray, and a second mold. The first mold has a working surface and a mounting surface. The support platform is set on the working surface and is provided with a positioning element and a placement groove. The positioning element is configured to position the outer shell, and the placement groove is configured to place the riveted nut. The tray is set on the mounting surface and is configured to support the outer shell to be riveted. The second mold is provided with a clearance hole, which cooperates with the positioning element.

[0062] In the technical solution of this application embodiment, the positioning component on the support platform engages with the hole on the outer casing, thereby enabling precise positioning of the outer casing and avoiding the difficulty in maintaining its position when manually handled. Simultaneously, when the outer casing is supported on the pallet and pressed against the surface of the support platform, the second mold moves towards the first mold until it presses onto the outer casing, thus pressing and limiting the outer casing to prevent movement during the riveting process and ensuring that the outer casing remains parallel and stable. In this way, the entire process eliminates the need for manual handling of the outer casing, reducing the impact of differences in operator strength and hand stability on the riveting operation, improving the consistency of riveting, and preventing the problem of misaligned nuts after riveting.

[0063] According to some embodiments of this application, Figure 1 This is a schematic diagram of the riveting mold in this application. Figure 2 This is a schematic diagram of the connection structure between the second mold and the pressure plate in this application. Figure 1 and combined Figure 2 As shown, this application provides a riveting mold, which includes a first mold 10, a support platform 11, a support plate 12, and a second mold 13. The first mold 10 has a working surface 102 and a mounting surface 107. The support platform 11 is disposed on the working surface 102 and is provided with a positioning element 111 and a placement groove 112. The positioning element 111 is configured to position the outer shell, and the placement groove 112 is configured to place the riveting nut. The support plate 12 is disposed on the mounting surface 107 and is configured to support the outer shell to be riveted. The second mold 13 is provided with a clearance hole 141 on the side facing the first mold 10. When the second mold 13 moves toward the first mold 10, the positioning element 111 extends into the clearance hole 141.

[0064] refer to Figure 1 As shown, in this embodiment, the mounting surface 107 is located on the left side of the first mold 10 in the X-axis direction, and the working surface 102 is located on the upper side of the first mold 10 in the Y-axis direction. Here, the X-axis direction is defined as the first direction, the Y-axis direction is defined as the second direction, and the X-axis and Y-axis are perpendicular to each other.

[0065] In this embodiment, the support platform 11 can be fixed to the working surface 102 of the first mold 10 by bolts or snap-fit. The specific method can be determined according to the actual situation, and this embodiment does not limit it.

[0066] In this embodiment, the positioning element 111 can be a positioning pin, a tapered column, etc., and the positioning element 111 mates with a hole on the outer casing. The positioning element 111 can be integrally formed with the support platform 11, or the positioning element 111 can be snapped onto the support platform 11; there is no limitation here.

[0067] Two or three positioning elements 111 can be provided on the side of the support platform 11 away from the first mold 10. At the same time, the number of placement grooves 112 is equal to the number of nuts to be riveted, and the specific number can be determined according to the actual situation. This specification does not limit this aspect in the embodiments.

[0068] This embodiment may include one or two equal support plates 12, which can be bolted to the mounting surface 107. When the side of the outer casing that needs to be riveted is placed on the support platform 11, the inside of the outer casing abuts against the support plate 12.

[0069] In this embodiment, the number of clearance holes 141 on the second mold 13 is equal to the number of positioning members 111. When the cylinder drives the second mold 13 to move downward along the Y-axis, after the second mold 13 is pressed onto the first mold 10, the positioning members 111 extend into the clearance holes 141 accordingly.

[0070] In the technical solution of this application embodiment, the positioning element 111 on the support platform 11 engages with the hole on the outer casing, thereby enabling precise positioning of the outer casing and avoiding the difficulty in maintaining the stability of the outer casing position when manually handled. Simultaneously, when the outer casing is supported on the tray 12 and pressed tightly against the surface of the support platform 11, the second mold 13 moves along the Y-axis towards the first mold 10 until it presses against the outer casing, thus providing a pressing and limiting function for the outer casing, preventing it from moving during the riveting process and ensuring that the outer casing remains parallel and stable. In this way, the entire process eliminates the need for manual handling of the outer casing, reducing the impact of differences in operator strength and hand stability on the riveting operation, improving the consistency of riveting, and thus avoiding the problem of misaligned nuts after riveting.

[0071] According to some embodiments of this application, such as Figure 1and combined Figure 2 As shown, the riveting mold also includes a pressure plate 14, which is disposed on the side of the second mold 13 facing the first mold 10, and a clearance hole 141 is disposed on the side of the pressure plate 14 facing the first mold 10.

[0072] In this embodiment, the pressure plate 14 can be bolted to the side of the second mold 13 facing the first mold 10, and the clearance hole 141 is provided on the side of the pressure plate 14 facing the first mold 10.

[0073] In use, the cylinder drives the second mold 13 to move downward along the Y-axis. At this time, the pressure plate 14 moves downward along the Y-axis. After the pressure plate 14 presses onto the first mold 10, the positioning part 111 extends into the clearance hole 141. The pressure plate 14 applies a force downward along the Y-axis to the nut to be riveted, so that the nut to be riveted is riveted to the corresponding outer casing.

[0074] According to some embodiments of this application, such as Figure 1 As shown, the side of the support platform 11 facing the pressure plate 14 is properly fitted with the side of the outer casing to be riveted.

[0075] Since the side of the bearing platform 11 facing the pressure plate 14 fits perfectly with the side of the outer shell box to be riveted, the bearing platform 11 can accurately position the outer shell box to be riveted, thereby improving the riveting qualification rate.

[0076] According to some embodiments of this application, such as Figure 2 and combined Figure 1 , Figure 3 As shown, the pressure plate 14 is provided with a slot 142 on the side facing the support platform 11, and the support platform 11 is provided with a protrusion 113 on the side facing the pressure plate 14, which cooperates with the slot 142.

[0077] In this embodiment, the protrusion 113 can be a protrusion, a bump, etc. The number of protrusions 113 is equal to the number of slots 142, and there is no limitation here.

[0078] When in use, when the pressure plate 14 is pressed onto the corresponding support platform 11, the pressure plate 14 can fall accurately onto the support platform 11, so as to achieve precise pressing of the outer casing on the support platform 11 by the pressure plate 14.

[0079] According to some embodiments of this application, such as Figure 2 and combined Figure 1 As shown, the pressure plate 14 is provided with a positioning groove 143 on the side facing the first mold 10, and the first mold 10 is provided with a first limiting member 103 on the side facing the pressure plate 14. The first limiting member 103 cooperates with the positioning groove 143.

[0080] In this embodiment, one or two equal positioning grooves 143 may be provided on the side of the pressure plate 14 facing the first mold 10, as shown in the reference. Figure 2 As shown, the positioning groove 143 can be located around the pressure plate 14. The specific location can be determined according to the actual situation. This specification does not limit this embodiment.

[0081] In this embodiment, the first limiting member 103 can be a protrusion, a limiting post, etc. The first limiting member 103 can be snapped onto the first mold 10, or the first limiting member 103 can be connected to the first mold 10 by bolts. The number of the first limiting members 103 can be equal to the number of the positioning grooves 143, which is not limited here.

[0082] When in use, when the second mold 13 moves the pressure plate 14 toward the first mold 10, the positioning groove 143 and the first limiting member 103 cooperate to ensure that the pressure plate 14 falls accurately onto the first mold 10, thus preventing the pressure plate 14 from shifting during the pressing process.

[0083] According to some embodiments of this application, a plurality of positioning elements 111 are provided on the bearing platform 11, and a plurality of clearance holes 141 are provided on the pressure plate 14, wherein the position of the clearance hole 141 corresponds to the position of the positioning element 111.

[0084] The structure of the positioning element 111 and the connection structure between the positioning element 111 and the support platform 11 in this embodiment can be referred to the above description, and will not be repeated here.

[0085] In this embodiment, two or three positioning elements 111 can be provided on the support platform 11, and two or three clearance holes 141 can be provided on the pressure plate 14. The number of positioning elements 111 is equal to the number of clearance holes 141.

[0086] In this way, by having multiple positioning elements 111 engage with the various holes on the outer casing, precise positioning of the outer casing can be achieved.

[0087] According to some embodiments of this application, the riveting die further includes an elastic buffer disposed between the pressure plate 14 and the second die 13.

[0088] The elastic buffer in this embodiment can be a spring, a rubber pad, etc., and is not limited here.

[0089] In this embodiment, the elastic buffer can be connected between the pressure plate 14 and the second mold 13 by bolts or snap-fit.

[0090] During use, when the pressure plate 14 is pressed downward along the Y-axis, the elastic buffer can buffer the instantaneous pressure of the pressure plate 14 on the rivet nut when the pressure plate 14 contacts the bearing platform 11, thus avoiding a rigid collision between the two.

[0091] According to some embodiments of this application, such as Figure 1 As shown, the length of the tray 12 is adjustable, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0092] In this embodiment, the tray 12 is a housing along a third direction, wherein the third direction is as follows: Figure 1 The Z-axis direction is defined in the diagram, where the X-axis, Y-axis, and Z-axis are all perpendicular to each other.

[0093] In this embodiment, the tray 12 may include multiple strips, and two adjacent strips are connected together along the Z-axis by bolts. In this way, the length of the tray 12 along the Z-axis can be adjusted by increasing or decreasing the number of corresponding strips.

[0094] It should be noted that the above-described pallet structure is merely an example. Other alternative structures can also be used. For instance, the pallet may include two slidably connected strips, and the length of the pallet can be adjusted by adjusting the sliding position of the two strips. This application does not impose any special restrictions on the specific structure of the pallet, as long as the above structure achieves the purpose of this application.

[0095] When in use, the length of the tray 12 along the Z-axis can be adjusted according to actual needs to adapt to different sizes of outer casings.

[0096] According to some embodiments of this application, the surface of the tray 12 is provided with a flexible layer.

[0097] The flexible layer in this embodiment can be made of rubber, plastic, etc., and is not limited here.

[0098] When in use, when the tray 12 supports the outer casing, the flexible layer on the tray 12 contacts the corresponding outer casing, thereby preventing the surface of the outer casing from being scratched.

[0099] According to some embodiments of this application, the positioning element 111 is detachably connected to the support platform 11.

[0100] In this embodiment, the positioning component 111 can be connected to the support platform 11 by bolts or snap-fit. In this way, when the model of the outer casing to be riveted changes, the positioning component 111 of the corresponding size can be replaced to achieve positioning of different models of outer casings.

[0101] According to some embodiments of this application, the inner wall of the placement groove 112 is provided with anti-slip texture or elastic pad, which is configured to prevent the riveting nut from rotating or shifting during the pressing process.

[0102] The elastic pad in this embodiment can be a rubber pad, a foam pad, etc., and is not limited here.

[0103] Since the inner wall of the placement groove 112 is provided with anti-slip texture or elastic pad, when the riveting nut is placed in the placement groove 112, the anti-slip texture or elastic pad can prevent the riveting nut from rotating or shifting during the pressing process, thereby improving the accuracy of the riveting nut during the pressing process.

[0104] According to some embodiments of this application, such as Figure 1 As shown, the first mold 10 is provided with a through hole 101.

[0105] In this embodiment, one or two through holes 101 can be provided on the first mold 10, but this is not limited here.

[0106] By providing through holes 101 on the first mold 10, the weight of the first mold 10 can be reduced.

[0107] According to some embodiments of this application, such as Figure 1 As shown, the first mold 10 includes a bottom surface 104, the area of ​​which is larger than the area of ​​the working surface 102. The working surface 102 and the bottom surface 104 are located on opposite sides of the first mold 10 along the second direction.

[0108] The second direction in this embodiment can be referred to the description above, and will not be repeated here.

[0109] Since the area of ​​the bottom surface 104 is larger than the area of ​​the working surface 102, the overall first mold 10 is trapezoidal, which improves the stability of the overall first mold 10 under the support of the bottom surface 104.

[0110] According to some embodiments of this application, such as Figure 4 and combined Figure 5 As shown, the riveting mold also includes a second limiting member 15, which is disposed on the mounting surface 107. The second limiting member 15 can move closer to or further away from the mounting surface 107. When the outer shell to be riveted is hung on the tray 12, the second limiting member 15 abuts against the inner wall of the outer shell.

[0111] In this embodiment, the second limiting member 15 can move closer to or further away from the mounting surface 107 along the X-axis direction.

[0112] In this embodiment, the second limiting member 15 can be a screw, an electric telescopic rod, etc. The specific one can be determined according to the actual situation, and this specification does not limit it in this embodiment.

[0113] When in use, when the outer casing is hung on the tray 12 and the outer casing is in contact with the corresponding support platform 11, the second limiting member 15 also abuts against the inner wall of the outer casing. In this way, under the limitation of the second limiting member 15, the outer casing can be prevented from tilting in the vertical direction.

[0114] According to some embodiments of this application, such as Figure 5 and combined Figure 4 As shown, the second limiting member 15 includes a plug-in plate 151, a snap-fit ​​block 152, a slide rod 153, and a pull plate 155. The first mold 10 is provided with a plug-in groove 105 and a sliding cavity 106. The sliding cavity 106 extends along a first direction. One end of the sliding cavity 106 is connected to the plug-in groove 105, and the other end is connected to the outside. The plug-in plate 151 is disposed in the plug-in groove 105. The slide rod 153 is located in the sliding cavity 106. The snap-fit ​​block 152 is slidably connected to the plug-in plate 151. One end of the slide rod 153 is connected to the snap-fit ​​block 152, and the other end is connected to the pull plate 155. The pull plate 155 is located outside the first mold 10 and is configured to drive the snap-fit ​​block 152 to move relative to the sliding cavity 106 along the first direction.

[0115] In this embodiment, the plug plate 151 is snapped into the corresponding plug slot 105, and the slide rod 153 is slidably disposed in the slide cavity 106. One end of the slide rod 153 is connected to the snap block 152 by bolts, and the other end is connected to the pull plate 155 by bolts. The pull plate 155 is located outside the first mold 10.

[0116] In use, by pulling the pull plate 155 to the left relative to the plug-in plate 151 along the X-axis, the pull plate 155 drives the locking block 152 to slide relative to the plug-in plate 151 along the X-axis via the slide rod 153. After the pull plate 155 is pulled to a position that can abut against the inner wall of the housing, the pull plate 155 stops moving. At this time, the housing is hung on the support plate 12, and at the same time, the housing fits against the corresponding support platform 11, and the pull plate 155 also abuts against the inner wall of the housing. In this way, under the constraint of the pull plate 155, the housing can be prevented from tilting in the vertical direction.

[0117] According to some embodiments of this application, such as Figure 5 As shown, the plug plate 151 has a groove 1511 on the side facing the sliding cavity 106, and the snap-fit ​​block 152 is at least partially located in the groove 1511.

[0118] By providing a sliding groove 1511 on the plug-in plate 151, it is convenient to slide the snap-fit ​​block 152 together with the plug-in plate 151.

[0119] According to some embodiments of this application, such as Figure 5 As shown, the second limiting member 15 also includes a fixing plate 154 and an elastic member 156. The fixing plate 154 is fixed in the sliding cavity 106, and the elastic member 156 is sleeved on the sliding rod 153. One end of the elastic member 156 abuts against the snap-fit ​​block 152, and the other end abuts against the fixing plate 154.

[0120] In this embodiment, the elastic element 156 can refer to a component that can deform under the action of external force and return to its original shape after the external force is removed. The elastic element 156 can be elastically compressed in the X-axis direction. The elastic element 156 can be made of metal or non-metal, such as leaf spring, coil spring, gas spring, rubber spring, etc. The specific type can be determined according to the actual situation, and this embodiment does not limit it.

[0121] In this embodiment, the fixing plate 154 can be bolted to the inner wall of the sliding cavity 106, which is not limited here.

[0122] In use, by pulling the pull plate 155 to the left relative to the plug-in plate 151 along the X-axis, the pull plate 155 drives the locking block 152 to slide relative to the plug-in plate 151 along the X-axis via the slide rod 153. Since one end of the elastic element 156 abuts against the locking block 152 and the other end abuts against the fixed plate 154, when the fixed plate 154 is fixed in position, when the locking block 152 slides to the left along the X-axis, it will simultaneously compress the corresponding elastic element 156. In this way, the pull plate 155 will be subjected to the reaction force of the elastic element 156.

[0123] After the pull plate 155 is pulled to a position where it can abut against the inner wall of the housing, a pad is used to secure the pull plate 155 to the left side of the first mold 10 along the X-axis, thus fixing the position of the pull plate 155. At this time, the housing is hung on the support plate 12, and the housing is in contact with the corresponding support platform 11, while the pull plate 155 also abuts against the inner wall of the housing.

[0124] Because the pull plate 155 is subjected to the reaction force of the elastic element 156, the position of the pull plate 155 is relatively stable under the limitation of the pad block, thereby preventing the pull plate 155 from moving along the X-axis when it comes into contact with the inner wall of the outer casing.

[0125] This application also provides a battery production line, including a riveting mold as described in any of the embodiments of this application.
