Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, and in particular to riveting components and riveting systems. Background Technology

[0002] In the product manufacturing process, there are often situations where two parts need to be press-fitted together. For example, in the assembly of electronic atomizing devices, a battery holder needs to be press-fitted into a battery sleeve to form the product. Related technologies use manual methods with jigs to install the battery holder into the battery sleeve. This manual pressing method is inefficient and cannot effectively control the riveting pressure, resulting in inconsistent assembly accuracy. Utility Model Content

[0003] Embodiments of this application provide riveting assemblies and riveting systems that can improve the efficiency and accuracy of riveting.

[0004] In a first aspect, embodiments of this application provide a riveting assembly. The riveting assembly includes a fixed base, a pressure head assembly, and a sensor. The pressure head assembly includes a connector and a riveting member, the riveting member being mounted on the connector, and the connector being movably connected to the fixed base. The sensor is disposed between the fixed base and the pressure head assembly for measuring the pressure between the fixed base and the pressure head assembly.

[0005] Optionally, the riveting component includes a riveting part and a mounting part. The mounting part is connected to the connector. The riveting part is located on the side of the mounting part away from the fixed base. The sensor is disposed between the mounting part and the fixed base.

[0006] Optionally, the riveting assembly includes an elastic element, one end of which abuts against the fixed seat and the other end of which abuts against the pressure head assembly. The elastic element is at least used to provide resistance that prevents the pressure head assembly from approaching the fixed seat.

[0007] Optionally, the riveting assembly includes a connecting post, an elastic element sleeved on the connecting post, and the connecting post being slidably connected to at least one of the fixed seat and the pressure head assembly.

[0008] Alternatively, the sensor may be mounted on either the pressure head assembly or the mounting base;

[0009] In the non-operating state, the sensor is spaced apart from the other of the pressure head assembly and the mounting base;

[0010] Alternatively, one end of the sensor abuts against the pressure head assembly, and the other end abuts against the mounting base.

[0011] Optionally, the fixed seat and the pressure head assembly are slidably connected in the longitudinal direction. The fixed seat includes a seat body and a sliding part, and the sliding part is slidably engaged with the connecting member.

[0012] Optionally, two sliding parts are provided, and the two sliding parts are arranged at a distance from each other.

[0013] Optionally, the pressure head assembly also includes a positioning post that protrudes from the side of the pressure head assembly away from the mounting base.

[0014] Secondly, embodiments of this application provide a riveting system. The riveting system includes the aforementioned riveting assembly, a drive assembly, and a moving module. The riveting assembly is mounted on the drive assembly, which drives the riveting assembly to move along the fixed base toward the pressure head assembly. The drive assembly is mounted on the moving module, which drives the drive assembly to move.

[0015] Optionally, the riveting system also includes a detection module, which is mounted on the mobile module.

[0016] The beneficial effects of this application are as follows: Unlike existing technologies, the riveting component can contact the workpiece to apply pressure and achieve workpiece assembly. Through the movable connection between the connector and the fixed base, the pressure head assembly can move closer to the fixed base under the riveting reaction force during the riveting process. In this case, by placing a sensor between the fixed base and the pressure head assembly, the pressure between them can be detected during the riveting process. The sensor, through feedback on the pressure between the fixed base and the pressure head assembly, can reflect the magnitude of the riveting pressure. Therefore, the riveting pressure can be controlled based on the measured pressure value. This method improves the safety of the riveting process and increases the efficiency and accuracy of riveting.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Combination Figure 1This application provides a riveting system 1. The riveting system 1 includes a riveting assembly 10, a driving assembly 20, and a moving module 30. The riveting assembly 10 is mounted on the driving assembly 20, and the driving assembly 20 is used to drive the riveting assembly 10 along the fixed base 11 (connected to...). Figure 2 ) Towards the pressure head assembly 12 (combined) Figure 2 The drive assembly 20 moves in the direction of the riveting component 10. During the riveting process, the drive assembly 20 can drive the riveting component 10 downwards and provide riveting force. The riveting component 10 requires high precision control of movement and driving force during the downward pressing process. The drive assembly 20 can be, for example, a drive device such as an electric cylinder. The electric cylinder has high displacement accuracy, which helps improve the assembly accuracy of the riveting component 10 during riveting. Furthermore, the electric cylinder receives a signal from the sensor 15 (in conjunction with...). Figure 2 It can also quickly adjust its movement trend after receiving feedback, which makes it easier to control the pressure.

[0022] The drive assembly 20 is mounted on the movable module 30. The movable module 30 is used to drive the drive assembly 20 to move. The riveting assembly 10 can follow the drive assembly 20 and move under the drive of the movable module 30. For example, if the X, Y, and Z directions are set to orthogonal, the direction of the fixed base 11 toward the pressure head assembly 12 is the Z direction. The movable module 30 can drive the drive assembly 20 to move in the X direction. The movable module 30 can also drive the drive assembly 20 to move in the Y direction. The movable module 30 can also drive the drive assembly 20 to move in both the X and Y directions respectively. By driving the drive assembly 20 to move, the movable module 30 can align the riveting assembly 10 with the workpiece to be riveted, so that the drive assembly 20 can press the workpiece by pressing down on the riveting assembly 10.

[0023] In some embodiments, multiple riveting assemblies 10 may be provided, thereby enabling the riveting system 1 to rivet multiple workpieces simultaneously.

[0024] In some embodiments, the riveting system 1 further includes a detection module 40, which is mounted on the movable module 30. After the riveting assembly 10 rivets, the movable module 30 can drive the detection module 40 to align with the workpiece, thereby detecting whether the riveting is successful. The detection module 40 can be, for example, a laser detector or a pressure detector. Taking the riveting of a battery bracket and a battery sleeve as an example, the distance between the battery bracket and the detection module 40 differs depending on whether the battery bracket and battery sleeve are riveted properly or not. The laser detector can determine whether the battery bracket is riveted properly by detecting the distance between the battery bracket and the laser detector. The pressure detector, for example, can drive the riveting assembly 20 to move downwards at a certain speed, and then determine whether the battery bracket is riveted properly based on the contact time between the pressure detector and the battery bracket.

[0025] Combination Figure 2 and Figure 3 This application provides a riveting assembly 10. The riveting assembly 10 includes a fixed base 11, a pressure head assembly 12, and a sensor 15. The fixed base 11 can be connected to a drive assembly 20. The pressure head assembly 12 is movably connected to the fixed base 11. Specifically, the pressure head assembly 12 includes a connector 121 and a riveting member 122. The riveting member 122 is mounted on the connector 121, and the connector 121 is movably connected to the fixed base 11. The sensor 15 is disposed between the fixed base 11 and the pressure head assembly 12 and is used to measure the pressure between the fixed base 11 and the pressure head assembly 12. The connector 121 and the fixed base 11 can be rotatably connected or slidably connected, which is not specifically limited here. The following embodiments will describe the two as slidably connected.

[0026] The riveting component 122 contacts the workpiece to apply pressure and assemble it. The connecting component 121 is movably connected to the fixed base 11, allowing the pressure head assembly 12 to move closer to the fixed base 11 under the reaction force during riveting. In this case, by placing a sensor 15 between the fixed base 11 and the pressure head assembly 12, the pressure between them can be detected during riveting. The sensor 15 provides feedback on the pressure between the fixed base 11 and the pressure head assembly 12, reflecting the magnitude of the riveting pressure. This allows for control of the riveting pressure based on the measured pressure value. This method improves the safety of the riveting process and increases its efficiency and accuracy.

[0027] In some embodiments, the riveting member 122 includes a riveting portion 1221 and a mounting portion 1222. The mounting portion 1222 is connected to the connector 121. The riveting portion 1221 is located on the side of the mounting portion 1222 facing away from the fixed base 11. The sensor 15 is disposed between the mounting portion 1222 and the fixed base 11. During the riveting process, when the drive assembly 20 drives the riveting assembly 10 to descend, the riveting portion 1221 can abut against the workpiece and apply pressure to the workpiece. The reaction force of the workpiece on the riveting portion 1221 can push the riveting member 122 towards the fixed base 11. During the movement, the mounting portion 1222 and the fixed base 11 clamp the sensor 15. During further riveting, the mounting portion 1222 will further tend to move towards the fixed base 11. Under this tendency, the sensor 15 can detect the pressure between the riveting member 122 and the fixed base 11. The drive assembly 20 can control the riveting process according to the detected pressure. For example, the riveting pressure can be controlled below a certain value, or an alarm can be triggered if it exceeds a certain value. In other embodiments, the sensor 15 can be disposed between the connector 121 and the mounting base 11.

[0028] In some embodiments, the riveting assembly 10 further includes an elastic element 13, one end of which abuts against the fixed base 11 and the other end against the pressure head assembly 12. The elastic element 13 at least provides resistance to prevent the pressure head assembly 12 from approaching the fixed base 11. Without the elastic element 13 or other components, during riveting, the support between the riveting member 122 and the fixed base 11 relies solely on the sensor 15 (the support at the end of the sliding stroke creates a movement limit, preventing the sensor 15 from sensing pressure changes). This could reduce the lifespan of the sensor 15. To improve this, the elastic element 13 provides support between the pressure head assembly 12 and the fixed base 11 without completely restricting the pressure head assembly 12 from approaching the fixed base 11. This reduces the pressure on the sensor 15 while supporting the pressure head assembly 12 without affecting the sensor's ability to sense pressure changes. In this case, the pressure value displayed by the sensor 15 may decrease, but the sensor 15 can still detect pressure changes, allowing control of riveting accuracy through these pressure variations.

[0029] Combination Figure 3 In some embodiments, the riveting assembly 10 further includes a connecting post 14, with an elastic element 13 sleeved on the connecting post 14. The connecting post 14 is slidably connected to at least one of the fixed base 11 and the pressure head assembly 12. The elastic element 13 can be, for example, a spring. By positioning the connecting post 14 between the springs, the stability of the spring during deformation can be increased, and the spring's deflection can be reduced. Specifically, the connecting post 14 can be fixedly connected to the fixed base 11 at one end and slidably connected to the pressure head assembly 12 at the other end. Alternatively, the connecting post 14 can be fixedly connected to the pressure head assembly 12 at one end and slidably connected to the fixed base 11 at the other end. Or, the connecting post 14 can be slidably connected to both the pressure head assembly 12 and the fixed base 11 at both ends. By setting the connecting post 14 to be slidably connected to at least one of the fixed base 11 and the pressure head assembly 12, the connecting post 14 can increase the stability of the spring without affecting the relative sliding of the pressure head assembly 12 relative to the fixed base 11.

[0030] In some embodiments, the sensor 15 is mounted on either the pressure head assembly 12 or the mounting base 11. The sensor 15 may be mounted on the mounting portion 1222 of the pressure head assembly 12 or on the connector 121 of the pressure head assembly 12. The sensor 15 may also be mounted on the mounting base 11, corresponding to the mounting portion 1222 or the connector 121.

[0031] In some embodiments, in the non-operating state, the sensor 15 is spaced apart from the other of the pressure head assembly 12 and the mounting base 11. This allows the sensor 15 to be free from pressure when not riveting, thus increasing its service life. During riveting, the pressure head assembly 12 moves closer to the mounting base 11, reducing the aforementioned distance until it comes into contact with the pressure head assembly 12, thereby enabling normal detection of the pressure between the pressure head assembly 12 and the mounting base 11. In other embodiments, one end of the sensor 15 abuts against the pressure head assembly 12, and the other end abuts against the mounting base 11.

[0032] In some embodiments, the fixing base 11 and the pressure head assembly 12 are slidably connected in the longitudinal direction. The fixing base 11 includes a base body 111 and a sliding part 112, which is slidably engaged with the connecting member 121. Further, the sliding part 112, the connecting member 121, the elastic member 13, and the sensor 15 are located between the base body 111 and the mounting part 1222. This arrangement allows for a more compact layout of the riveting assembly 10, which helps reduce interference during the riveting process and facilitates the arrangement of multiple pressure head assemblies 12, thereby improving riveting efficiency.

[0033] In some embodiments, two sliding portions 112 are provided, and the two sliding portions 112 are arranged relatively apart. The arrangement of two sliding portions 112 helps to increase the stability of the sliding connection between the fixed base 11 and the pressure head assembly 12. Further, two elastic members 13 are provided, and the two elastic members 13 are arranged relatively apart. The sensor 15 is located between the two sliding portions 112 and between the two elastic members 13. In this way, the sensor 15 can be surrounded between the elastic members 13 and the sliding portions 112, which can reduce the impact of the movement offset of the fixed base 11 and the pressure head assembly 12 on the detection accuracy of the sensor 15.

[0034] In some embodiments, the pressure head assembly 12 further includes a positioning post 123, which protrudes from the side of the pressure head assembly 12 away from the fixing base 11. The workpiece to be riveted can be fixed by a fixture. The fixture may be provided with positioning holes corresponding to the positioning post 123. During the riveting process, by extending the positioning post 123 into the positioning hole, the riveting part 1221 can be aligned with the workpiece, thereby achieving precise riveting.

[0035] Furthermore, at least two positioning posts 123 are provided, with at least one positioning post 123 provided on each of the opposite sides of the riveting part 1221. Providing at least two positioning posts 123 increases the positioning accuracy. By providing positioning posts 123 on each of the opposite sides of the riveting part 1221, positioning can be achieved on both sides of the riveting part 1221, further facilitating the alignment of the riveting part 1221 with the workpiece.

[0036] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
