Description

Technical Field

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

[0002] At present, most battery top covers are generally fixed by riveting after pre-assembly. However, the existing riveting tooling has the problem of insufficient positioning accuracy when placing the battery top cover, which makes the battery top cover easily riveted off-center during the subsequent riveting process, increasing the probability of defects or poor quality of the finished battery top cover. Summary of the invention

[0003] The present application provides a riveting device, which aims to solve the problem of insufficient yield of riveting battery top covers by existing riveting tooling.

[0004] In order to solve the above problems, the present application provides a riveting device on the one hand, which includes: a riveting mechanism, a fixing mechanism and a limiting mechanism; the riveting mechanism is arranged opposite to the fixing mechanism and is slidably connected to the fixing mechanism; the side of the fixing mechanism facing the riveting mechanism is configured to place the product to be riveted, and the product to be riveted is located on the sliding path of the riveting mechanism; the limiting mechanism includes: two limiting components slidably arranged on the side of the fixing mechanism facing the riveting mechanism, and the two limiting components are respectively located on opposite sides of the product to be riveted, and can clamp the product to be riveted together after sliding.

[0005] In the above scheme, two slidable stopper assemblies are arranged on the side of the fixing mechanism facing the riveting mechanism, and the two stopper assemblies are respectively located on the opposite sides of the product to be riveted, and can clamp the product to be riveted together after sliding, so that the product to be riveted can be guided and positioned under the clamping of the two stopper assemblies. Such an arrangement can not only reduce the probability of scratching the product to be riveted and the stopper assemblies, but also improve the positioning accuracy of the riveting device for placing the product to be riveted, thereby reducing the probability of defects or defects in the finished product of the product to be riveted.

[0006] In one embodiment, the limiting assembly includes: a first limiting member and a second limiting member; the first limiting member and the second limiting member are both slidably disposed on a side of the fixing mechanism facing the riveting mechanism, and the first limiting member is located between the second limiting member and the fixing mechanism; wherein the first limiting members of the two limiting assemblies can jointly clamp the product to be riveted after sliding; and the second limiting members of the two limiting assemblies can jointly clamp the product to be riveted after sliding.

[0007] Therefore, the first limiting member and the second limiting member of the two limiting assemblies can be used to clamp the product to be riveted respectively, so that the product to be riveted can be better positioned and guided, thereby further reducing the probability of the product to be riveted being offset.

[0008] In one embodiment, the first limit member and the second limit member are slidably connected; when the two first limit members jointly clamp the product to be riveted, the two second limit members slide on the two first limit members respectively, and jointly clamp the product to be riveted after sliding.

[0009] Therefore, the sliding connection between the first limiting member and the second limiting member can be utilized to reduce the avoidance space required for the sliding of the first limiting member and the second limiting member, thereby reducing the space occupied by the limiting assembly on the fixing mechanism.

[0010] In one embodiment, the first stopper has a first notch on a side facing the product to be riveted, and the second stopper has a second notch on a side facing the product to be riveted; wherein the first notch and the second notch are configured to accommodate the product to be riveted.

[0011] Thus, the first limiting member and the second limiting member of the two limiting assemblies can respectively accommodate the product to be riveted by using the first notch and the second notch, so as to reduce the probability of positional displacement of the product to be riveted when being clamped.

[0012] In one embodiment, a side of the second limiting member in contact with the product to be riveted has a plurality of spaced grooves.

[0013] Therefore, the groove can be used to reduce the contact area between the second limiting member and the product to be riveted, so as to reduce the probability of overall deformation of the edge of the product to be riveted that contacts the second limiting member.

[0014] In one embodiment, the second limiting member is in point contact or line contact with the product to be riveted.

[0015] Therefore, the contact area between the second stopper and the product to be riveted can be further reduced by using point contact or line contact, so as to reduce the probability of cross contamination between the second stopper and the product to be riveted.

[0016] In one embodiment, the limiting mechanism further includes: a driving component; the driving component is disposed on the fixing mechanism and is respectively connected to the two limiting components, and the driving component can drive the two limiting components to slide.

[0017] Therefore, the driving component can be used to automatically drive the limiting component to improve the production efficiency of the riveting device.

[0018] In one embodiment, the driving assembly includes: two driving members; the two driving members are both arranged on the fixing mechanism and are respectively connected to the two limiting assemblies, and the two driving members can respectively drive the two limiting assemblies to slide.

[0019] Therefore, the two driving members can be used to automatically drive the limit assembly respectively, so as to improve the driving flexibility of the limit assembly.

[0020] In one embodiment, the limiting assembly includes: a first limiting member and a second limiting member; the first limiting member is slidably disposed on the fixing mechanism, and the first limiting member is located between the second limiting member and the fixing mechanism, and is slidably connected to the second limiting member; the two driving members are respectively connected to the second limiting members of the two limiting assemblies, and the driving member can drive the second limiting member to drive the first limiting member to slide, so that the first limiting members of the two limiting assemblies jointly clamp the product to be riveted; when the two first limiting members jointly clamp the product to be riveted, the driving member can also drive the second limiting member to slide on the first limiting member, so that the second limiting members of the two limiting assemblies jointly clamp the product to be riveted.

[0021] Therefore, a single driving member can utilize the sliding connection between the first limit member and the second limit member to control the first limit member and the second limit member in a linkage manner, so as to reduce the sliding stroke required to be designed for the first limit member while realizing automatic driving of the first limit member and the second limit member, thereby reducing the space occupied by the limit assembly on the fixing mechanism.

[0022] In one embodiment, the fixing mechanism includes: a bearing component and a positioning component; the bearing component is arranged opposite to the riveting mechanism and is slidably connected to the riveting mechanism; the positioning component is arranged on a side of the bearing component facing the riveting mechanism, and is configured to place the product to be riveted, and the positioning component can also position the placed product to be riveted.

[0023] Therefore, the positioning component can be used to position the placed product to be riveted, so as to reduce the probability of positional deviation of the product to be riveted during the clamping process of the limited position component.

[0024] In one embodiment, the positioning component includes: a placement table and an adsorption component; the placement table is arranged on the supporting component and is configured to place the product to be riveted; the adsorption component is arranged on the placement table and can adsorb the product to be riveted.

[0025] Therefore, the adsorption member can be used to adsorb and position the product to be riveted placed on the placement table, so as to reduce the probability of positional deviation of the product to be riveted during the clamping process of the limited position component.

[0026] In one embodiment, the positioning assembly further includes: a stop member; the stop member is disposed on the mounting platform and is located between the two limit assemblies, and when the two limit assemblies jointly clamp the product to be riveted, the stop member also contacts the two limit assemblies respectively.

[0027] Therefore, the stopper can be used to limit the sliding stroke of the two limit assemblies, so as to reduce the probability of damage to the product to be riveted due to unlimited clamping of the limit assemblies.

[0028] In one embodiment, the riveting mechanism includes: a sliding component and a riveting component; the sliding component is arranged opposite to the fixing mechanism and is slidably connected to the fixing mechanism; the riveting component is arranged on a side of the sliding component facing the fixing mechanism, and the product to be riveted is located on the sliding path of the riveting component

[0029] Therefore, the sliding assembly can be used to drive the riveting assembly to slide, so as to rivet the product to be riveted placed on the fixing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0049] At present, most battery top covers are generally pre-assembled on the riveting tool and then fixed by riveting. However, since the position and size of the existing riveting tool are fixed, there is a problem of insufficient positioning accuracy when the battery top cover (the product to be riveted) is placed on the riveting tool. That is, since the position and size of the positioning groove of the riveting tool used to place the battery top cover are fixed, the battery top cover is not only prone to scratches with the riveting tool during the placement process, but also prone to deviation after placement, which in turn causes the battery top cover to be riveted off-center during the subsequent riveting process, which undoubtedly increases the probability of defects or poor quality of the finished battery top cover.

[0050] In order to solve the above technical problems, the embodiment of the present application provides a riveting device, which is provided with two slidable limiter components on a fixing mechanism for placing the product to be riveted (such as a battery top cover), and the two limiter components are also located on opposite sides of the product to be riveted, and can clamp the product to be riveted together after sliding, so that the product to be riveted can be guided and positioned under the clamping of the two limiter components. Such a setting can not only reduce the probability of scratching the product to be riveted and the limiter components, but also improve the positioning accuracy of the riveting device for placing the product to be riveted, thereby reducing the probability of defects or defects in the finished product of the product to be riveted.

[0051] See also Figures 1 to 3 , Figure 1 is a schematic structural diagram of a riveting device 10 provided in an embodiment of the present application, Figure 2 yes Figure 1 The structural diagram of the riveting mechanism 100 is shown in FIG. Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure of the middle riveting device 10 along V-V.

[0052] The riveting device 10 can be used to place the product 20 to be riveted and perform riveting on the placed product 20 to be riveted to complete the assembly of the product 20 to be riveted. Figure 1 to Figure 2 As shown, the riveting device 10 may include: a riveting mechanism 100, a fixing mechanism 200 and a limiting mechanism 300. The riveting mechanism 100 is arranged opposite to the fixing mechanism 200 and is slidably connected to the fixing mechanism 200. The side of the fixing mechanism 200 facing the riveting mechanism 100 can be used to place the product 20 to be riveted, and the product 20 to be riveted can also be located on the sliding path of the riveting mechanism 100. The limiting mechanism 300 may include: two limiting components 310 slidably arranged on the side of the fixing mechanism 200 facing the riveting mechanism 100, and the two limiting components 310 are also respectively located on the opposite sides of the product 20 to be riveted, and can clamp the product 20 to be riveted together after sliding.

[0053] The riveting mechanism 100 can slide in a direction close to or away from the fixing mechanism 200, and when the riveting mechanism 100 slides in a direction close to the fixing mechanism 200, the riveting mechanism 100 can perform riveting on the product 20 to be riveted preassembled on the fixing mechanism 200. After the riveting of the product 20 to be riveted is completed, the riveting mechanism 100 can slide in a direction away from the riveting mechanism 100 to reset, so as to prepare for the next riveting, and the product 20 to be riveted that has completed riveting can be taken out from the fixing mechanism 200.

[0054] The fixing mechanism 200 may have a riveting position on the side facing the riveting mechanism 100, and the product 20 to be riveted may be placed on the riveting position, so that the product 20 to be riveted may be located on the sliding path of the riveting mechanism 100. At the same time, the fixing mechanism 200 may also position the product 20 to be riveted on the riveting position to reduce the probability that the product 20 to be riveted moves away from the riveting position during the clamping process of the two limiting components 310. In addition, the fixing mechanism 200 may also support the product 20 to be riveted placed on the riveting position, so that the product 20 to be riveted may be deformed under the riveting of the riveting mechanism 100, so as to achieve riveting fixation of the product 20 to be riveted.

[0055] The two stopper assemblies 310 can be arranged opposite to each other and spaced apart, and can slide in a direction close to or away from each other, and the riveting position (the product to be riveted 20) can be located between the two stopper assemblies 310. When the two stopper assemblies 310 slide in a direction close to each other, the two stopper assemblies 310 can clamp the product to be riveted 20 together, and align and position the product to be riveted 20 for riveting by the riveting mechanism 100. When the product to be riveted 20 is riveted, the two stopper assemblies 310 can slide in a direction away from each other to reset, so as to prepare for the next clamping, and the product to be riveted 20 that has been riveted can be taken out from the fixing mechanism 200.

[0056] In the above scheme, two slidable stopper assemblies 310 are arranged on the fixing mechanism 200 for placing the product 20 to be riveted, and the two stopper assemblies 310 are respectively located on opposite sides of the product 20 to be riveted, and can clamp the product 20 to be riveted together after sliding, so that the product 20 to be riveted can be guided and positioned under the clamping of the two stopper assemblies 310. Such an arrangement can not only reduce the probability of scratching the product 20 to be riveted and the stopper assemblies 310, but also improve the positioning accuracy of the riveting device 10 for placing the product 20 to be riveted, thereby reducing the probability of defects or defects in the finished product 20 to be riveted.

[0057] The riveting mechanism 100 can slide in a direction close to the fixing mechanism 200 to perform riveting on the product 20 to be riveted at the riveting position. Figures 2 to 3As shown, the riveting mechanism 100 may include: a sliding assembly 110 and a riveting assembly 120. The sliding assembly 110 may be arranged opposite to the fixing mechanism 200 and may be slidably connected to the fixing mechanism 200. The riveting assembly 120 may be arranged on a side of the sliding assembly 110 facing the riveting mechanism 100, and the product 20 to be riveted may be located on the sliding path of the riveting assembly 120.

[0058] In order to achieve a sliding connection with the fixing mechanism 200, the sliding assembly 110 may include: a sliding plate 111 and a guide sleeve 112. Figures 2 to 3 As shown, the sliding plate 111 can be arranged opposite to the fixing mechanism 200, and can slide in a direction close to or away from the fixing mechanism 200. At the same time, the side of the sliding plate 111 facing the fixing mechanism 200 can be connected to the riveting assembly 120 to drive the riveting assembly 120 to slide in a direction close to or away from the fixing mechanism 200. In addition, the side of the sliding plate 111 away from the fixing mechanism 200 can also be connected to a driving structure such as a cylinder or a motor to provide a driving force for the sliding of the sliding plate 111.

[0059] The guide sleeve 112 may be disposed on the sliding plate 111, and the guide sleeve 112 may be slidably connected to the fixing mechanism 200, so that the sliding plate 111 may slide through the guide sleeve 112. At the same time, the number of the guide sleeves 112 may be two, and the two guide sleeves 112 may be respectively arranged on opposite ends of the sliding plate 111, so as to improve the sliding stability of the sliding plate 111 by using the two guide sleeves 112. For example, the guide sleeve 112 may be embedded in the sliding plate 111, and have a guide hole 1121 exposed on the side of the sliding plate 111 facing the fixing mechanism 200, and the corresponding structural member of the fixing mechanism 200 may be slidably inserted into the guide hole 1121, so as to realize the sliding connection between the sliding plate 111 and the fixing mechanism 200.

[0060] The riveting assembly 120 is disposed on the side of the sliding plate 111 facing the fixing mechanism 200, and the riveting assembly 120 can slide along with the sliding plate 111 to perform riveting on the product 20 to be riveted at the riveting position. Figures 2 to 3 As shown, the riveting assembly 120 may include: a riveting member 121, a connecting member 122, and a pressing member 123. The riveting member 121 may be arranged on the side of the sliding plate 111 facing the fixing mechanism 200, and may slide with the sliding plate 111 in a direction close to the fixing mechanism 200 to rivet the product 20 to be riveted. The connecting member 122 is arranged on the side of the riveting member 121 away from the sliding plate 111, and may slide with the riveting member 121. The pressing member 123 is arranged on the side of the connecting member 122 away from the sliding plate 111, and may slide with the sliding plate 111 in a direction close to the fixing mechanism 200 to press the product 20 to be riveted against the fixing mechanism 200.

[0061] The riveted part 121 may include: a fixing portion 1211 and a riveted portion 1212. The fixing portion 1211 is disposed on a side of the sliding plate 111 facing the fixing mechanism 200, and may slide with the sliding plate 111. The riveted portion 1212 is connected to a side of the fixing portion 1211 away from the sliding plate 111, and the riveted portion 1212 may also be disposed opposite to the riveting position, and may rivet the product 20 to be riveted after sliding with the fixing portion 1211. In this embodiment, the fixing portion 1211 and the riveted portion 1212 may be made of a metal material with a relatively high hardness, so as to improve the structural strength of the fixing portion 1211 and the riveted portion 1212, and ensure that the product 20 to be riveted can be deformed under the riveting of the riveted portion 1212.

[0062] The connecting member 122 may include: a first connecting portion 1221, an elastic portion 1222 and a second connecting portion 1223. The first connecting portion 1221 is arranged on a side of the fixed portion 1211 away from the sliding plate 111, the elastic portion 1222 is arranged on a side of the first connecting portion 1221 away from the sliding plate 111, and the second connecting portion 1223 is arranged on a side of the elastic portion 1222 away from the sliding plate 111. At the same time, the first connecting portion 1221, the elastic portion 1222 and the second connecting portion 1223 can all be arranged around the riveting portion 1212 to avoid the riveting portion 1212. That is, one end of the riveting portion 1212 away from the fixed portion 1211 can be penetrated by the first connecting portion 1221, the elastic portion 1222 and the second connecting portion 1223.

[0063] The pressing member 123 may include: a pressing portion 1231 and an adapter portion 1232. The pressing portion 1231 and the adapter portion 1232 may be arranged on the side of the elastic portion 1222 away from the sliding plate 111, and the adapter portion 1232 may also be arranged around the pressing portion 1231. The second connecting portion 1223 may be arranged around the adapter portion 1232 and may be connected to the adapter portion 1232. At the same time, one end of the pressing portion 1231 away from the elastic portion 1222 may also protrude from the side of the second connecting portion 1223 away from the sliding plate 111. In addition, the pressing portion 1231 may also be arranged around the riveting portion 1212 to avoid the riveting portion 1212. That is, one end of the riveting portion 1212 away from the fixing portion 1211 may be penetrated by the first connecting portion 1221, the elastic portion 1222, the second connecting portion 1223 and the pressing member 123.

[0064] When the riveting mechanism 100 needs to perform riveting on the product 20 to be riveted, the sliding plate 111 can slide in the direction close to the fixing mechanism 200, and drive the end of the pressing portion 1231 away from the elastic portion 1222 to press the product 20 to be riveted, so as to press the product 20 to be riveted tightly against the fixing mechanism 200. At the same time, the sliding plate 111 can also continue to slide in the direction close to the fixing mechanism 200, so as to drive the riveting portion 1212 to perform riveting on the product 20 to be riveted pressed by the pressing portion 1231, and in this process, the pressing portion 1231 can drive the second connecting portion 1223 to press the elastic portion 1222 through the adapter portion 1232, so that the elastic portion 1222 undergoes elastic deformation to avoid the pressing portion 1231, the adapter portion 1232 and the second connecting portion 1223.

[0065] In the above scheme, the riveting mechanism 100 can be slidably connected to the fixing mechanism 200 by using the sliding component 110, and can use the riveting component 120 arranged on the side of the sliding component 110 facing the fixing mechanism 200 to rivet the product 20 to achieve the riveting fixation of the riveting mechanism 100 on the product 20 to be riveted.

[0066] In some embodiments, the specific structure of the riveting mechanism 100 can be adaptively adjusted according to the design requirements, and is not limited to the scheme shown in the aforementioned embodiment. For example, the sliding plate 111 can also be slidably connected to the fixing mechanism 200 through other sliding structures such as slide rails or slide grooves, rather than being slidably connected to the fixing mechanism 200 through the guide sleeve 112. For another example, the elastic portion 1222 can be an elastic body arranged between the first connecting portion 1221 and the second connecting portion 1223, or a spring arranged between the first connecting portion 1221 and the second connecting portion 1223. For another example, the pressing portion 1231 can also be arranged on the side of the second connecting portion 1223 away from the sliding plate 111, rather than being arranged on the side of the elastic portion 1222 away from the sliding plate 111. Of course, in addition to the above scheme, there can be a variety of deformation embodiments of the riveting mechanism 100, which are not listed one by one in this embodiment.

[0067] Please combine Figure 3 See also Figures 4 to 5 , Figure 4 yes Figure 1 The structural diagram of the fixing mechanism 200 is shown in FIG. Figure 5 yes Figure 4 A local enlarged schematic diagram of point A in the middle.

[0068] The fixing mechanism 200 can be arranged opposite to the riveting mechanism 100 and can be slidably connected to the riveting mechanism 100, and the side of the fixing mechanism 200 facing the riveting mechanism 100 can also be used to place the product 20 to be riveted. Figure 3 to Figure 4As shown, the fixing mechanism 200 may include: a bearing assembly 210 and a positioning assembly 220. The bearing assembly 210 may be arranged opposite to the riveting mechanism 100 and may be slidably connected to the riveting mechanism 100. The positioning assembly 220 may be arranged on a side of the bearing assembly 210 facing the riveting mechanism 100 and may be used to place the product 20 to be riveted, and the positioning assembly 220 may also position the product 20 to be riveted.

[0069] In order to achieve a sliding connection with the riveting mechanism 100, the bearing assembly 210 may include: a bearing plate 211 and a sliding rod 212. Figure 3 to Figure 4 As shown, the bearing plate 211 can be arranged opposite to the sliding plate 111, and a positioning assembly 220 can be provided on the side of the bearing plate 211 facing the sliding plate 111. One end of the sliding rod 212 can be connected to the bearing plate 211, and the other end can be slidably inserted into the guide hole 1121, so that the sliding plate 111 can slide along the sliding rod 212 through the guide sleeve 112 to achieve the sliding connection between the sliding plate 111 and the bearing plate 211. At the same time, the number of the sliding rod 212 can be two, and the two sliding rods 212 can be matched with the two guide sleeves 112 respectively to improve the sliding stability of the sliding plate 111.

[0070] In some embodiments, the bearing assembly 210 may further include: a connecting block 213 and two limiting blocks 214. Figure 4 As shown, the connecting block 213 can be slidably arranged on the side of the bearing plate 211 facing the sliding plate 111, and the side of the connecting block 213 away from the bearing plate 211 can be provided with a positioning assembly 220. Two limiting blocks 214 can be respectively arranged on opposite sides of the connecting block 213, and both of the limiting blocks 214 can be slidably connected with the connecting block 213, and can provide limiting and guiding for the sliding of the connecting block 213. For example, one of the connecting block 213 and the limiting block 214 can be provided with a slider, and the other can be provided with a slide groove for accommodating the slider, and the connecting block 213 and the limiting block 214 can be slidably connected by the slider and the slide groove. With such a configuration, the sliding of the connecting block 213 can be used to adjust the position of the positioning assembly 220 on the bearing plate 211.

[0071] In some embodiments, the bearing assembly 210 may further include: a connecting rod 215 and a push-pull rod 216. Figure 4 As shown, the two opposite ends of the connecting rod 215 can be connected to the connecting block 213 and the push-pull rod 216 respectively, and the number of the connecting rods 215 can be two. The push-pull rod 216 can be arranged spaced apart from the connecting block 213 in the sliding direction of the connecting block 213, and the push-pull rod 216 can be held by an operator to push and pull, so as to drive the connecting block 213 to slide on the carrying plate 211. Of course, in addition to the above-mentioned manual driving solution, the connecting block 213 can also be driven by electric drive.

[0072] In some embodiments, the bearing assembly 210 may further include a stop block 217. Figure 4 As shown, the stop block 217 can be arranged on the side of the connection block 213 away from the carrier plate 211, and the stop block 217 can contact the second connection part 1223 after sliding to limit the sliding stroke of the second connection part 1223, thereby protecting the positioning assembly 220 arranged on the connection block 213 and the product to be riveted 20 placed on the positioning assembly 220. There can be two stop blocks 217, and the two stop blocks 217 can be arranged on the connection block 213 at intervals, and the positioning assembly 220 can be arranged between the two stop blocks 217.

[0073] The positioning assembly 220 may be disposed on a side of the connection block 213 away from the carrier plate 211, and the positioning assembly 220 may also be located on the sliding path of the riveting member 121, and may have the aforementioned riveting position for placing the product 20 to be riveted. At the same time, the positioning assembly 220 may also position the product 20 to be riveted placed on the riveting position, so as to reduce the probability of positional displacement of the product 20 to be riveted during the process of being clamped by the two limiting assemblies 310.

[0074] In the above scheme, the fixing mechanism 200 can be slidably connected to the riveting mechanism 100 by using the bearing assembly 210, and can place and position the product 20 to be riveted by using the positioning assembly 220 arranged on the side of the bearing assembly 210 facing the riveting mechanism 100, so as to reduce the probability of positional displacement of the product 20 to be riveted during the process of being clamped by the two limiting assemblies 310, thereby improving the positioning accuracy of the riveting device 10 for placing the product 20 to be riveted.

[0075] In some embodiments, the positioning assembly 220 may include: a placement table 221 and an adsorption member 222. Figure 3 and Figure 5 As shown, the placement platform 221 can be disposed on the bearing assembly 210 and can be used to place the product 20 to be riveted. The adsorption member 222 can be disposed on the placement platform 221 and can adsorb the product 20 to be riveted.

[0076] The placement platform 221 can be arranged on the side of the connection block 213 away from the carrier plate 211 and between the two stop blocks 217, and the placement platform 221 has a concave mold 2211 (riveting position) for placing the product 20 to be riveted on the side away from the connection block 213. The adsorption member 222 can be arranged on the concave mold 2211, and the adsorption member 222 can adsorb the product 20 to be riveted placed on the concave mold 2211 to locate the position of the product 20 to be riveted on the concave mold 2211, thereby reducing the probability of positional displacement of the product 20 to be riveted during the process of being clamped by the two limiting components 310. Among them, the adsorption member 222 can be a structural member with adsorption capacity such as a vacuum suction cup.

[0077] In the above scheme, a placement table 221 is provided for placing the product 20 to be riveted, and an adsorption member 222 provided on the placement table 221 is used to adsorb the product 20 to be riveted, so that the product 20 to be riveted can be positioned on the placement table 221, so as to reduce the probability of positional displacement of the product 20 to be riveted during the process of being clamped by the two limiting components 310, thereby improving the positioning accuracy of the riveting device 10 for placing the product 20 to be riveted.

[0078] In some embodiments, the positioning assembly 220 may further include a stopper 223. Figure 3 and Figure 5 As shown, the stopper 223 can be disposed on the mounting platform 221 and can be located between two limiting components 310 , and when the two limiting components 310 jointly clamp the product 20 to be riveted, the stopper 223 can contact the two limiting components 310 respectively.

[0079] The stopper 223 may be a convex column embedded in the placement platform 221, and may be protruded from the side of the placement platform 221 away from the connecting block 213. At the same time, the number of the stopper 223 may be two, and the two stopper 223 may be respectively located on opposite sides of the die 2211. When the two limit assemblies 310 clamp the product 20 to be riveted together, the stopper 223 may be located between the two limit assemblies 310, and may contact the two limit assemblies 310 respectively, so as to limit the sliding stroke of the limit assemblies 310, thereby protecting the product 20 to be riveted clamped by the two limit assemblies 310.

[0080] In the above scheme, a stop member 223 is arranged on the placement table 221, and the stop member 223 can contact the two limit components 310 respectively after the two limit components 310 jointly clamp the product 20 to be riveted, so that the stop member 223 can limit the sliding stroke of the limit component 310 to reduce the probability of damage to the product 20 to be riveted due to unlimited clamping of the limit component 310.

[0081] See also Figures 6 to 8, Figure 6 yes Figure 1 A schematic diagram of the connection structure of the fixing mechanism 200 and the limiting mechanism 300, Figure 7 yes Figure 6 A schematic diagram of the connection structure of the fixing mechanism 200 and the limiting mechanism 300 in another state, Figure 8 yes Figure 6 A partial enlarged schematic diagram of point B in the middle. Fig. 9 yes Figure 7 A partial enlarged schematic diagram of point C in the middle.

[0082] The limiting mechanism 300 can be used to clamp the product 20 to be riveted, so as to guide and position the product 20 to be riveted placed on the fixing mechanism 200. Figure 6 to Figure 7 As shown, the limiting mechanism 300 may include: two limiting components 310 slidably arranged on the side of the fixing mechanism 200 facing the riveting mechanism 100, and the two limiting components 310 are also respectively located on the opposite sides of the product 20 to be riveted, and can clamp the product 20 to be riveted together after sliding.

[0083] For example, when the two stopper assemblies 310 are in the initial position, there can be a large space between the two stopper assemblies 310, so that the product 20 to be riveted and pressed can be placed on the fixing mechanism 200, thereby reducing the probability of scratching the product 20 to be riveted and the stopper assemblies 310. After the two stopper assemblies 310 slide in the direction close to each other, the two stopper assemblies 310 can push the product 20 to be riveted and pressed from both sides, and clamp the product 20 to be riveted and pressed together after sliding to the predetermined position. In this process, if the product 20 to be riveted and pressed has a problem of being placed off-center, the stopper assemblies 310 can push the product 20 to be riveted and pressed to correct and return it to its original position, and clamp and position the product 20 to be riveted and pressed after the product 20 to be riveted and pressed has returned to its original position.

[0084] In the above scheme, two slidable stopper assemblies 310 are arranged on the fixing mechanism 200 for placing the product 20 to be riveted, and the two stopper assemblies 310 are respectively located on opposite sides of the product 20 to be riveted, and can clamp the product 20 to be riveted together after sliding, so that the product 20 to be riveted can be guided and positioned under the clamping of the two stopper assemblies 310. Such an arrangement can not only reduce the probability of scratching the product 20 to be riveted and the stopper assemblies 310, but also improve the positioning accuracy of the riveting device 10 for placing the product 20 to be riveted, thereby reducing the probability of defects or defects in the finished product 20 to be riveted.

[0085] The position limiting assembly 310 can be used to guide and position the product 20 to be riveted, and the position limiting assembly 310 can include: a first position limiting member 311 and a second position limiting member 312. Figures 6 to 8As shown, the first stopper 311 and the second stopper 312 are both slidably disposed on the side of the fixing mechanism 200 facing the riveting mechanism 100, and the first stopper 311 is also located between the second stopper 312 and the fixing mechanism 200. The first stopper 311 of the two stopper assemblies 310 can jointly clamp the product 20 to be riveted after sliding, and the second stopper 312 of the two stopper assemblies 310 can also jointly clamp the product 20 to be riveted after sliding.

[0086] The first stoppers 311 of the two stopper assemblies 310 can be arranged oppositely and spaced apart on the carrier plate 211, and respectively located on opposite sides of the product 20 to be riveted, and the two first stoppers 311 can slide in a direction approaching or moving away from each other. Similarly, the second stoppers 312 of the two stopper assemblies 310 can be arranged oppositely and spaced apart on a side of the first stopper 311 away from the carrier plate 211, and respectively located on opposite sides of the product 20 to be riveted, and the two second stoppers 312 can also slide in a direction approaching or moving away from each other.

[0087] When the two first stoppers 311 slide in a direction approaching each other, that is, in a direction approaching the product 20 to be riveted, the two first stoppers 311 can clamp the product 20 to be riveted together to guide and position the product 20 to be riveted, so that the riveting mechanism 100 can perform riveting. When the two first stoppers 311 slide in a direction away from each other, that is, in a direction away from the product 20 to be riveted, the two first stoppers 311 can be spaced apart so that the product 20 to be riveted after riveting can be taken out of the fixing mechanism 200. When the two first stoppers 311 clamp the product 20 to be riveted together, the two first stoppers 311 also contact the stoppers 223 respectively, so that the stoppers 223 can be used to limit the two first stoppers 311 from continuing to slide.

[0088] When the two second stoppers 312 slide in a direction approaching each other, that is, in a direction approaching the product 20 to be riveted, the two second stoppers 312 can clamp the product 20 to be riveted together to guide and position the product 20 to be riveted, so that the riveting mechanism 100 can perform riveting. When the two second stoppers 312 slide in a direction away from each other, that is, in a direction away from the product 20 to be riveted, the two second stoppers 312 can be spaced apart so that the product 20 to be riveted after riveting can be taken out of the fixing mechanism 200. When the two second stoppers 312 clamp the product 20 to be riveted together, the two second stoppers 312 also contact the stoppers 223 respectively, so that the stoppers 223 can be used to limit the two second stoppers 312 from sliding further.

[0089] In the above scheme, the limiting component 310 may include: a first limiting member 311 and a second limiting member 312. The first limiting member 311 and the second limiting member 312 can be used to clamp the product 20 to be riveted respectively to meet the positioning requirements of the product 20 to be riveted, so that the product 20 to be riveted can be better positioned and guided, thereby further reducing the probability of the product to be riveted being offset.

[0090] In some embodiments, the first stopper 311 and the second stopper 312 may also be linked. Figures 6 to 8 As shown, the first limit member 311 and the second limit member 312 can be slidably connected, and when the two first limit members 311 jointly clamp the product 20 to be riveted, the two second limit members 312 can slide on the two first limit members 311 respectively, and can jointly clamp the product 20 to be riveted after sliding.

[0091] The first stopper 311 and the second stopper 312 can be slidably connected by a sliding structure such as a slide rail, a slide rod or a slide groove. At the same time, an elastic member can be provided between the first stopper 311 and the second stopper 312, and the elastic member can abut against the first stopper 311 and the second stopper 312 respectively. In addition, before the second stopper 312 slides relative to the first stopper 311, the orthographic projection of the second stopper 312 on the first stopper 311 can be located within the coverage range of the first stopper 311, so that the second stopper 312 can lag behind the first stopper 311 to clamp the product 20 to be riveted.

[0092] For example, the two second stoppers 312 can be driven to slide in the direction close to the product 20 to be riveted, and can push the two first stoppers 311 to slide in the direction close to the product 20 to be riveted through the elastic member. After sliding, the two first stoppers 311 can first clamp the product 20 to be riveted, and after clamping the product 20 to be riveted, they are restricted by the stopper 223 and cannot continue to slide. At this time, the two second stoppers 312 can continue to be driven to slide in the direction close to the product 20 to be riveted, and the elastic member will be elastically deformed under the pressure of the first stopper 311 and the second stopper 312 to avoid the sliding of the second stopper 312, so that the two second stoppers 312 can clamp the product 20 to be riveted together after sliding, and the two first stoppers 311 will also maintain the clamping state of the product 20 to be riveted under the reaction force of the elastic member.

[0093] In the above scheme, by setting the first limit member 311 and the second limit member 312 to be slidably connected, the first limit member 311 and the second limit member 312 can be linked to reduce the avoidance space required for the sliding of the first limit member 311 and the second limit member 312, thereby reducing the space occupied by the limit assembly 310 on the fixing mechanism 200.

[0094] In some embodiments, in addition to the first limiting member 311 clamping the product 20 to be riveted first, the second limiting member 312 can also clamp the product 20 to be riveted first, and the first limiting member 311 clamps the product 20 to be riveted later. It is only necessary that before the second limiting member 312 slides relative to the first limiting member 311, the positive projection of the first limiting member 311 on the second limiting member 312 can be located within the coverage range of the second limiting member 312, so that the first limiting member 311 can lag behind the second limiting member 312 to clamp the product 20 to be riveted.

[0095] For example, the two first stoppers 311 may be driven to slide toward the direction of the product 20 to be riveted, and the two second stoppers 312 may be pushed by the elastic member to slide toward the direction of the product 20 to be riveted. After sliding, the two second stoppers 312 may first clamp the product 20 to be riveted, and after clamping the product 20 to be riveted, they are restricted by the stopper 223 and cannot continue to slide. At this time, the two first stoppers 311 may continue to be driven to slide toward the direction of the product 20 to be riveted, and the elastic member may be elastically deformed under the pressure of the first stoppers 311 and the second stoppers 312 to avoid the sliding of the first stoppers 311, so that the two first stoppers 311 may clamp the product 20 to be riveted together after sliding, and the two second stoppers 312 may also maintain the clamping state of the product 20 to be riveted under the reaction force of the elastic member.

[0096] In some embodiments, in addition to realizing the sequential clamping of the first stopper 311 and the second stopper 312 by an elastic member, the sequential clamping of the first stopper 311 and the second stopper 312 can also be realized by other locking structures. That is, the first stopper 311 and the second stopper 312 can be fixed by a locking structure, and when the first stopper 311 slides into place (after clamping the product 20 to be riveted), the locking of the locking structure can be released, so that the second stopper 312 can continue to be driven to slide in a direction close to the product 20 to be riveted. The locking and unlocking of the locking structure can be controlled by the control center (such as the main board) of the riveting device 10.

[0097] In some embodiments, in addition to the first stopper 311 and the second stopper 312 clamping the product 20 to be riveted and pressed successively, the first stopper 311 and the second stopper 312 can also clamp the product 20 to be riveted and pressed simultaneously. For example, one of the first stopper 311 and the second stopper 312 can be driven to slide relative to the other, and after sliding to the corresponding position (such as the end of the slide rail), drive the other to slide in the direction close to the product 20 to be riveted and pressed, so as to clamp the product 20 to be riveted and pressed simultaneously after sliding. Alternatively, the first stopper 311 and the second stopper 312 can be connected to form a whole, so as to clamp the product 20 to be riveted and pressed after being driven to slide synchronously.

[0098] like Figure 8 As shown, in order to improve the clamping stability of the two first stoppers 311 and the two second stoppers 312 on the product 20 to be riveted, the first stopper 311 may have a first notch 3111 on the side facing the product 20 to be riveted, and the second stopper 312 may have a second notch 3121 on the side facing the product 20 to be riveted. The first notch 3111 and the second notch 3121 may both be used to accommodate the product 20 to be riveted.

[0099] When the two first stoppers 311 slide in a direction close to the product 20 to be riveted, a part of the product 20 to be riveted can be located in the first notches 3111 of the two first stoppers 311, so that the first notches 3111 are used to limit the product 20 to be riveted, thereby reducing the probability of displacement of the product 20 to be riveted during the clamping process of the two first stoppers 311. Similarly, when the two second stoppers 312 slide in a direction close to the product 20 to be riveted, a part of the product 20 to be riveted can also be located in the second notches 3121 of the two second stoppers 312, so that the second notches 3121 are used to limit the product 20 to be riveted, thereby reducing the probability of displacement of the product 20 to be riveted during the clamping process of the two second stoppers 312.

[0100] In some embodiments, after the two first stoppers 311 clamp the product 20 to be riveted, the two first stoppers 311 can also be spliced ​​together, so that the first notches 3111 of the two first stoppers 311 can jointly form a stop groove to accommodate the complete product 20 to be riveted. Similarly, after the two second stoppers 312 clamp the product 20 to be riveted, the two second stoppers 312 can also be spliced ​​together, so that the second notches 3121 of the two second stoppers 312 can jointly form another stop groove to accommodate the complete product 20 to be riveted. Such a configuration can reduce the probability of positional displacement of the product 20 to be riveted after being clamped and positioned.

[0101] In the above scheme, a first notch 3111 is provided on a side of the first limiting member 311 facing the product 20 to be riveted, and a second notch 3121 is provided on a side of the second limiting member 312 facing the product 20 to be riveted, and the first notch 3111 and the second notch 3121 are both used to accommodate the product 20 to be riveted, so that the product 20 to be riveted can be limited by the first notch 3111 and the second notch 3121 during the clamping process, so as to reduce the probability of positional displacement of the product 20 to be riveted during the clamping process.

[0102] like Fig. 9As shown, in order to reduce the probability of overall deformation of the edge of the product 20 to be riveted due to clamping by the second stopper 312 , the side of the second stopper 312 in contact with the product 20 to be riveted may also have a plurality of spaced grooves 3122 .

[0103] The second stopper 312 has a contact surface 3123 located in the second notch 3121, and the contact surface 3123 can contact the product 20 to be riveted. A plurality of grooves 3122 can be provided on the contact surface 3123, and the plurality of grooves 3122 can be arranged at intervals in the direction surrounding the product 20 to be riveted, so as to form continuous protrusions and depressions on the contact surface 3123. When the second stopper 312 slides in the direction approaching the product 20 to be riveted, the plurality of protrusions on the contact surface 3123 can contact the product 20 to be riveted, so as to reduce the contact area between the second stopper 312 and the product 20 to be riveted.

[0104] In the above solution, the groove 3122 provided on the contact surface 3123 can be used to reduce the contact area between the second stopper 312 and the product 20 to be riveted, so as to reduce the probability that the edge of the product 20 to be riveted and pressed in contact with the second stopper 312 is deformed as a whole due to clamping. At the same time, the reduction in the contact area between the second stopper 312 and the product 20 to be riveted can also further reduce the probability of cross contamination between the second stopper 312 and the product 20 to be riveted. That is, contaminants that may exist on the second stopper 312 and / or the product 20 to be riveted are not easily cross-transferred.

[0105] In order to further reduce the probability of cross contamination between the second stopper 312 and the product to be riveted 20 , the second stopper 312 and the product to be riveted 20 may also be in point contact or line contact.

[0106] For example, the multiple continuous protrusions on the contact surface 3123 may be arranged in an angular shape, and the edges of the protrusions may be used to contact the product 20 to be riveted, so as to achieve line contact between the second stopper 312 and the product 20 to be riveted. Similarly, the multiple continuous protrusions on the contact surface 3123 may be arranged in a pyramid shape, and the cone tips of the protrusions may be used to contact the product 20 to be riveted, so as to achieve point contact between the second stopper 312 and the product 20 to be riveted.

[0107] In the above scheme, the point contact or line contact between the second limiter 312 and the product to be riveted 20 can be used to further reduce the contact area between the second limiter 312 and the product to be riveted 20, which can not only reduce the probability of the edge of the product to be riveted 20 being clamped and deformed as a whole, but also reduce the probability of cross-contamination between the second limiter 312 and the product to be riveted 20.

[0108] In some embodiments, the side of the first limiting member 311 that contacts the product 20 to be riveted may also be provided with a groove 3122 like the second limiting member 312 to reduce the contact area between the first limiting member 311 and the product 20 to be riveted.

[0109] In order to improve the automation level of the riveting device 10, the limiting mechanism 300 may further include: a driving component 320. Figure 6 to Figure 7 As shown, the driving assembly 320 can be disposed on the fixing mechanism 200 and can be connected to the two limiting assemblies 310 respectively, and the driving assembly 320 can drive the two limiting assemblies 310 to slide.

[0110] The driving assembly 320 can provide a driving force after being powered on to drive the two limiting assemblies 310 to slide. The driving assembly 320 can be connected to the two second limiting members 312, and can drive the two second limiting members 312 to slide in the direction close to the product 20 to be riveted, so as to drive the two first limiting members 311 to slide in the direction close to the product 20 to be riveted. After sliding, the two first limiting members 311 can first clamp the product 20 to be riveted, and the two second limiting members 312 can slide relative to the two first limiting members 311 respectively under the drive of the driving assembly 320, so as to continue to slide in the direction close to the product 20 to be riveted, so as to clamp the product 20 to be riveted together after sliding. Of course, in some embodiments, the driving assembly 320 can also be connected to the two first limiting members 311 to drive the first limiting member 311 to drive the second limiting member 312 to slide.

[0111] In the above scheme, a driving component 320 is provided to be connected to two limit components 310 respectively, and the two limit components 310 can slide under the drive of the driving component 320, so that the riveting device 10 can use the driving component 320 to automatically drive the limit component 310 to slide, so as to clamp the riveted product 20, thereby improving the production efficiency of the riveting device 10.

[0112] When the two limiting components 310 are independently driven by the driving component 320, the driving component 320 may include: two driving members 321. Figure 6 to Figure 7 As shown, the two driving members 321 can be disposed on the fixing mechanism 200 and can be respectively connected to the two limiting components 310 , and the two driving members 321 can respectively drive the two limiting components 310 to slide.

[0113] The two driving members 321 can be respectively arranged on the two limiting blocks 214, and the following description will be given by taking a single driving member 321 as an example. Figure 6 to Figure 7As shown, the driving member 321 may include: a driving portion 3211 and a transmission portion 3212. The driving portion 3211 may be disposed on a side of the limit block 214 away from the carrier plate 211, and the driving portion 3211 may provide a driving force after being powered on. The transmission portion 3212 may be connected to the driving portion 3211 and the limit assembly 310, respectively, and may slide under the drive of the driving portion 3211, and the sliding direction of the transmission portion 3212 is also parallel to the sliding direction of the limit assembly 310.

[0114] In some embodiments, the driving part 3211 may be a cylinder, and the transmission part 3212 may be a guide rod connecting the driving part 3211 and the position limiting assembly 310. Of course, the driving part 3211 may not be limited to a cylinder, and the driving part 3211 may also be other structures such as a motor that can provide driving force, and the transmission part 3212 may not be limited to a guide rod, as long as the transmission part 3212 can drive the position limiting assembly 310 to slide under the drive of the driving part 3211.

[0115] In the above scheme, the driving component 320 includes two driving members 321, and the two driving members 321 can be respectively connected to the two limiting components 310, and can respectively drive the two limiting components 310 to slide, so that the sliding of the two limiting components 310 can remain independent, so as to improve the driving flexibility of the limiting components 310.

[0116] like Figure 6 to Figure 7 As shown, in order to enable the two limit assemblies 310 to clamp the product 20 to be riveted and pressed under the drive of the two driving members 321, the two driving members 321 can be respectively connected to the second limit members 312 of the two limit assemblies 310, and the driving member 321 can drive the second limit member 312 to drive the first limit member 311 to slide, so that the first limit members 311 of the two limit assemblies 310 jointly clamp the product 20 to be riveted and pressed. After the two first limit members 311 jointly clamp the product 20 to be riveted and pressed, the driving member 321 can also drive the second limit member 312 to slide on the first limit member 311, so that the second limit members 312 of the two limit assemblies 310 jointly clamp the product 20 to be riveted and pressed.

[0117] The transmission part 3212 of the driving member 321 can be connected to the second limiting member 312, and the two driving members 321 can respectively drive the two second limiting members 312 to slide in the direction close to the product 20 to be riveted, and the two second limiting members 312 can respectively drive the two first limiting members 311 to slide in the direction close to the product 20 to be riveted. At the same time, the two first limiting members 311 can first clamp the product 20 to be riveted after sliding, and the two second limiting members 312 can continue to slide relative to the two first limiting members 311 under the drive of the two driving members 321, and can clamp the product 20 to be riveted after sliding. Among them, the process of the first limiting member 311 and the second limiting member 312 clamping the product 20 to be riveted in sequence is referred to the above embodiment of the limiting assembly 310, which will not be repeated here.

[0118] In the above scheme, a single driving member 321 can utilize the sliding connection between the first limit member 311 and the second limit member 312 to drive the first limit member 311 and the second limit member 312 in a linkage manner, so as to realize the automatic driving of the first limit member 311 and the second limit member 312 while reducing the avoidance space required for the sliding of the first limit member 311 and the second limit member 312, thereby reducing the space occupied by the limit assembly on the fixing mechanism.

[0119] In some embodiments, the first position-limiting member 311 and the second position-limiting member 312 can slide independently in addition to being linked. For example, the number of the driving members 321 can be four, and two driving members 321 can be connected to the two first position-limiting members 311 respectively, and the remaining two driving members 321 can be connected to the two second position-limiting members 312 respectively, so that the first position-limiting member 311 and the second position-limiting member 312 can be driven independently, without being limited to the above-mentioned linkage scheme.

[0120] In some embodiments, in addition to being driven by an independent driven component 320, the two limit components 310 can also be driven by a synchronous driven component 320. For example, the drive component 320 may include: a motor, a synchronous gear, and two racks. The synchronous gear may be connected to the output end of the motor and may be meshed with the two racks, respectively, and the two racks may also be connected to the two limit components 310, respectively. When the motor drives the synchronous gear to start rotating, the two racks meshed with the synchronous gear may respectively drive the two limit components 310 to slide synchronously in the direction of approaching or moving away from each other. Of course, in addition to the scheme shown in the above embodiment, the drive component 320 may have a variety of drive forms, and the drive component 320 only needs to drive the two limit components 310 to slide, which are not listed one by one in this embodiment.

When the two first stoppers 311 complete the clamping, the two second stoppers 312 can be driven to slide in a direction close to the product 20 to be riveted, and after sliding, they jointly clamp the riveting block 26 to improve the positioning accuracy of the riveting block 26. When the riveted product 20 is positioned as a whole, the pressing portion 1231 can slide toward the direction close to the riveting block 26 and press the riveting block 26, the upper plastic 25, the top cover sheet 24 and the lower plastic 23 against the die 2211, while the riveting portion 1212 can slide toward the direction close to the pole 21 and rivet the end of the pole 21 away from the adsorption piece 222, so that the end of the pole 21 is deformed and fixed to the riveting block 26.
