[0044] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0045] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0046] It should be understood that the terms "length," "width," "upper," "lower," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of this application. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0047] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0048] An embodiment of the present application proposes a riveting device for riveting a motor and an eccentric block to form a riveted workpiece, that is, the riveted workpiece includes a motor and an eccentric block fixedly connected. Since the motor and the eccentric block are riveted at a riveting station far away from the operator, the safety hazards that may be caused to the operator during the riveting process can be avoided.

[0049] Wherein, the motor shaft of the motor passes through the eccentric block, and after riveting, the eccentric block is fixedly connected to the motor shaft.

[0050] Please refer to Figures 1 to 4 In one embodiment of the present application, the riveting device 100 includes a punch 10, a rivet head 20, a mounting mechanism 30, a conveying mechanism 40 and a blanking mechanism 50, wherein the mounting mechanism 30, the conveying mechanism 40 and the blanking mechanism 50 are all arranged on the punch 10.

[0051] The punch press 10 is provided with a riveting area. The rivet head 20 is located above the riveting area and is slidably connected to the punch press 10 along a first direction (Z direction in the figure). The first direction is a vertical direction.

[0052] The mounting mechanism 30 is used to accommodate the motor 201 and the eccentric mass 202. It is understood that the mounting mechanism 30 should be provided with mounting slots for the motor 201 and the eccentric mass 202 to respectively position the motor 201 and the eccentric mass 202. The operator places the motor 201 and the eccentric mass 202 on the mounting mechanism 30 in advance outside the riveting area.

[0053] The conveying mechanism 40 is used to drive the installation mechanism 30 to move in a second direction (the X direction in the figure) perpendicular to the first direction to move toward or away from the riveting area, thereby bringing the eccentric weight 202 and the motor 201 closer to the riveting area. In other words, the motor 201 and the eccentric weight 202 can be moved to the riveting area with the installation mechanism 30 to complete the loading, and the riveting is completed in the riveting area by the rivet head 20. This can avoid safety accidents that may occur due to accidental touch or machine malfunction when the operator manually places the motor 201 and the eccentric weight 202 in the riveting area, thereby improving safety.

[0054] The unloading mechanism 50 includes a stripper plate 51 and a clamping member 52. The clamping member 52 can be connected to the riveted workpiece and drives the riveted workpiece to rotate toward the stripper plate 51 for stripping. It is understood that the clamping member 52 and the riveted workpiece are detachably connected. For example, the clamping member 52 can be connected to the riveted workpiece by means of a magnetic connection or a snap connection.

[0055] The riveting device 100 can drive the installation mechanism 30 via the transmission mechanism 40 to deliver the motor 201 and the eccentric block 202 to the riveting area. Since the motor 201 and the eccentric block 202 can be manually placed in advance outside the riveting area, it can avoid safety accidents that may be caused by accidental touch or machine failure when the operator manually places the motor 201 and the eccentric block 202 in the riveting area, thereby improving safety. In addition, the riveting device 100 can realize the automation of the loading, riveting, and unloading processes through the coordinated work of the installation mechanism 30, the transmission mechanism 40, and the unloading mechanism 50, eliminating the need for too many operators to perform various operations during the riveting process, saving labor costs, and improving production efficiency, thereby effectively solving the technical problems of large safety hazards, high labor costs, and low production efficiency in the existing riveting production process of the motor 201 and the eccentric block 202.

[0056] It can be understood that the riveting device 100 further includes a control mechanism (not shown) electrically connected to the conveying mechanism 40 and the rivet head 20 for controlling the movement of the conveying mechanism 40 and the rivet head 20 .

[0057] The riveting process is as follows: first, the operator places the motor 201 and the eccentric block 202 on the mounting mechanism 30; then, the operator can start the control mechanism by stepping on the foot switch or manually triggering the switch; secondly, the control mechanism controls the conveying mechanism 40 to drive the mounting mechanism 30 to move to the riveting area along the second direction, and triggers the rivet head 20 to work along the first direction, and the rivet head 20 returns to the initial position after completing riveting; secondly, the clamping member 52 rotates and drives the riveted workpiece to rotate to disengage from the mounting mechanism 30 until it rotates to the stripping plate 51 for stripping. At the same time, the mounting mechanism 30 is reset to facilitate the operator to place a new product to be processed again.

[0058] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the transmission mechanism 40 includes a connected driving member 41 and a connecting member 42. The side of the connecting member 42 facing away from the driving member 41 is connected to the mounting mechanism 30. The driving member 41 is used to drive the connecting member 42 and the mounting mechanism 30 to move in the second direction. In this way, the driving member 41 does not directly act on the mounting mechanism 30 to drive it to reciprocate in the second direction. Instead, the connecting member 42 acts as a bridge and transmits the force exerted by the driving member 41 to the mounting mechanism 30. In other words, the connecting member 42 acts as a buffer.

[0059] The driving member 41 is a driving cylinder, and the driving shaft of the driving cylinder is connected to the connecting member 42. It is understood that in other embodiments of the present application, the driving member 41 can also be a linear driving member such as an electric cylinder or a hydraulic cylinder, but is not limited thereto.

[0060] It is understandable that in other embodiments of the present application, the connecting member 42 may also be omitted, and the driving member 41 is directly connected to the mounting mechanism 30 and drives the mounting mechanism 30 to reciprocate along the second direction, which is not limited here.

[0061] Please refer to Figures 1 to 3 In one embodiment of the present application, the transmission mechanism 40 further includes a gear 43 and a rack 44 in transmission connection, and the gear 43 and the rack 44 are meshed. The gear shaft 431 of the gear 43 extends along a third direction perpendicular to the first direction and the second direction (the Y direction in the figure), the pressing member 52 is provided on the gear shaft 431, the rack 44 extends along the second direction and one end of the rack 44 is fixedly connected to the connecting member 42, and the driving member 41 can also drive the rack 44 to move along the second direction through the connecting member 42 to drive the gear 43 and the pressing member 52 to rotate, and is used to drive the riveted workpiece to rotate to the stripper plate 51 for stripping.

[0062] In other words, the driver 41 can drive the rack 44 to reciprocate linearly in the second direction. Since the gear 43 is meshed with the rack 44, the rack 44 can drive the gear 43 to rotate. In this way, the driver 41 can both drive the mounting mechanism 30 to reciprocate in the second direction to move the motor 201 and the eccentric weight 202 to the riveting area, and can also drive the gear 43 to rotate, moving the pressing member 52 and the riveted workpiece from the riveting area to the stripper plate 51, thereby completing the unloading process. In this way, the same driver 41 can achieve both loading and unloading, saving power and making the entire process highly automated, thereby improving work efficiency.

[0063] The connecting member 42 may be fixedly connected to the end of the rack 44 by screw connection, snap connection, or the like.

[0064] It is understandable that in other embodiments of the present application, the gear 43 can also be driven to rotate by another driving member 41 alone. In this case, the gear 43 does not need to be engaged with the rack 44, that is, the movement of the gear 43 and the rack 44 are independent, which is not limited here.

[0065] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7In one embodiment of the present application, the transmission mechanism 40 further includes a limiting member 45 and an elastic member 46. The ends of the elastic member 46 are respectively connected to the mounting mechanism 30 and the connecting member 42. A strip-shaped hole 61 is defined in one of the mounting mechanism 30 and the rack 44, and a stop post 62 is defined in the other. The stop post 62 is inserted into the strip-shaped hole 61. In this way, when one of the mounting mechanism 30 and the rack 44 is stationary, the other of the mounting mechanism 30 and the rack 44 can move a preset adjustment distance. That is, the mounting mechanism 30 and the rack 44 can have relative movement of the preset adjustment distance. It will be understood that the preset adjustment distance of the relative movement depends on the length of the strip-shaped hole 61 along the second direction.

[0066] The side of the mounting mechanism 30 facing away from the connecting member 42 can abut against the limiting member 45. That is, after the rack 44 drives the mounting mechanism 30 to move a certain distance, the mounting mechanism 30 can abut against the limiting member 45. If the rack 44 continues to move in the subsequent process, the mounting mechanism 30 will remain stationary. Since the connecting member 42 is fixedly connected to the rack 44, the connecting member 42 can also continue to move and compress the elastic member 46 located between the connecting member 42 and the mounting mechanism 30. The compression deformation of the elastic member 46 continues to increase. At the same time, the gear 43 rotates and drives the pressing member 52 to rotate toward the motor 201.

[0067] Furthermore, when the mounting mechanism 30 abuts the stopper 45, the eccentric weight 202 is in the riveting zone, and the connecting member 42 and the rack 44 can continue to move in the second direction under the drive of the driving member 41 until the pressing member 52 rotates to above the motor 201 and connects to the motor 201, and the rivet head 20 rivets the motor 201 and the eccentric weight 202 to form a riveted workpiece. In other words, the motor 201 and the eccentric weight 202 first move to the riveting zone, and then the pressing member 52 rotates to directly above the motor 201 and connects to the motor 201. The two actions are sequentially timed, which can avoid jamming caused by interference between the pressing member 52 and the mounting mechanism 30.

[0068] For details, please refer to Figure 1 and Figure 2 The transmission mechanism 40 further includes a limiting post 47, which is disposed on a side of the rack 44 facing away from the driving member 41 and can abut against the rack 44. After the mounting mechanism 30 remains stationary, the connecting member 42 and the rack 44 can continue to move in the second direction under the drive of the driving member 41 until the rack 44 abuts against the limiting post 47. At this time, the pressing member 52 rotates to above the motor 201 and is connected to the motor 201. The rivet head 20 rivets the motor 201 and the eccentric block 202 to form a riveted workpiece.

[0069] Among them, when the clamping member 52 is connected to the motor 201, the clamping member 52 can clamp the motor 201 provided on the mounting mechanism 30, thereby avoiding relative displacement between the motor 201 and the eccentric block 202. When the rivet head 20 is pressed down under the action of the press, the accuracy of the riveting position of the motor 201 and the eccentric block 202 can be improved, thereby improving the product stability of the riveted workpieces in the same batch.

[0070] For details, please refer to Figures 1 to 3 、 Figure 6 and Figure 7 In the embodiment of the present application, a channel 63 extending along the second direction is opened on the mounting mechanism 30, the rack 44 is movably arranged in the channel 63, the strip hole 61 is opened on the side wall of the mounting mechanism 30 and is connected to the channel 63, and the stop column 62 is protruded on the side wall of the rack 44.

[0071] It can be understood that in other embodiments of the present application, the strip hole 61 can also be opened on the side wall of the rack 44. Accordingly, the stop column 62 is protruded on the inner wall of the channel 63, and the stop column 62 can also be passed through the strip hole 61 to achieve stroke adjustment.

[0072] It can be understood that in other embodiments of the present application, the channel 63 can also be omitted. When the strip hole 61 is opened on the mounting mechanism 30, the strip hole 61 is a blind hole; when the strip hole 61 is opened on the side wall of the rack 44, the stop column 62 is protruded on the outer wall of the mounting mechanism 30, and the stop column 62 can also be passed through the strip hole 61 for stroke adjustment, thereby realizing relative movement between the mounting mechanism 30 and the rack 44.

[0073] Please refer to Figures 1 to 5 In one embodiment of the present application, the riveting device 100 further includes a support plate 64, and the gear shaft 431 passes through the support plate 64 and extends outward, so that the relative position between the gear 43 and the support plate 64 does not change, that is, the gear 43 only rotates in the vertical plane and does not move along the second direction. One end of the clamping member 52 is fixedly connected to the gear shaft 431, and the other end is provided with a connecting magnet 521. The clamping member 52 can be connected to the motor 201 by magnetic attraction to drive the riveted workpiece to rotate and disengage from the mounting mechanism 30. In this way, the original structure of the motor 201 can be used to achieve the connection between the motor 201 and the clamping member 52, without the need for an additional connecting structure. The connection relationship between the clamping member 52 and the motor 201 is simple and not prone to failure.

[0074] Specifically, the unloading mechanism 50 also includes a clamping member 53, which is sleeved on and fixedly connected to the gear shaft 431. The pressing member 52 is strip-shaped and one end of which is fixedly connected to the clamping member 53 by a screw. The end of the pressing member 52 away from the clamping member 53 is provided with a slot 522 that matches the shape of the motor 201 to limit the position of the motor 201. When the pressing member 52 rotates above the motor 201 and connects to the motor 201, the motor 201 can be partially accommodated in the slot 522. Correspondingly, a connecting magnet 521 is provided on the other side of the pressing member 52 away from the slot 522 to ensure that the magnetic attraction between it and the motor 201 is moderate.

[0075] Please refer to Figure 1 and Figure 3 In one embodiment of the present application, a clearance groove 54 is formed on the stripper plate 51. The size of the riveted workpiece is larger than the size of the clearance groove 54, and the clearance groove 54 can be penetrated at the end of the pressing member 52 away from the gear shaft 431. In this way. During the rotation of the gear 43, the clearance groove 54 can be penetrated at the end of the pressing member 52 away from the gear shaft 431, and the riveted workpiece is stopped by the stripper plate 51 due to its size limitation. As the pressing member 52 continues to rotate, the riveted workpiece is separated from the pressing member 52 and the material is stripped.

[0076] Furthermore, the stripper plate 51 forms a preset angle with the horizontal plane, so that after the riveted workpiece is separated from the pressing member 52, the riveted workpiece can slide along the stripper plate 51 under the action of its gravity to complete the unloading. No additional power drive is required, saving power consumption.

[0077] Specifically, the stripper plate 51 is fixed to a fixing block 65 by screws, so as to facilitate adjustment of the angle of the preset angle between the stripper plate 51 and the horizontal plane. It is understood that the installation position and number of the screws can be set according to the needs and are not limited here.

[0078] Please refer to Figure 1 、 Figure 2 and Figure 5 In one embodiment of the present application, a punching machine 10 includes a table 11 and a base 12 disposed on the table 11. The riveting area, the mounting mechanism 30, the conveying mechanism 40, and the blanking mechanism 50 are all disposed on the base 12. A T-shaped connecting groove 13 is formed on the table 11, and the base 12 is fixed to the table 11 via screws disposed in the connecting groove 13. Furthermore, the position of the base 12 can be easily changed, thereby adjusting the positions of the riveting area, the mounting mechanism 30, the conveying mechanism 40, and the blanking mechanism 50 to ensure the accuracy of the relative position of the rivet head 20 and the eccentric block 202.

[0079] The base 12 is provided with two side pressure plates 66 spaced apart from each other. Guide grooves 67 extending along the second direction are defined on the side pressure plates 66. The connector 42 and the mounting mechanism 30 are partially received in the guide grooves 67. Thus, the side pressure plates 66 guide the movement of the connector 42 and the mounting mechanism 30, preventing them from deviating from the second direction.

[0080] It can be understood that the connecting member 42 , the mounting mechanism 30 , the rack 44 , and the limiting member 45 are all located between the two side pressure plates 66 .

[0081] Please refer to Figures 1 to 4 In one embodiment of the present application, the mounting mechanism 30 includes a connecting seat 31 , a first mounting seat 32 and a second mounting seat 33 .

[0082] The connecting seat 31 is connected to the connecting member 42 and can be slidably disposed on the base 12 along the second direction under the action of the connecting member 42. Accordingly, the channel 63 is also opened on the connecting seat 31, and the side wall of the connecting seat 31 can abut against the limiting member 45.

[0083] The first mounting seat 32 is fixedly mounted on the connecting seat 31 and is used to place the eccentric mass 202. The second mounting seat 33 is arranged on the first mounting seat 32 so as to be liftable along a first direction and is used to place the motor 201. In this way, the installation height of the motor 201 can be adjusted so that the motor shafts 2011 of motors 201 of different sizes are maintained at the same height, which has strong applicability. The base 2012 of the motor 201 and the eccentric mass 202 have a preset distance on the mounting mechanism 30, wherein the preset distance refers to the minimum distance between the base 2012 and the eccentric mass 202 along the third direction, that is, the eccentric mass 202 is riveted to the motor shaft 2011 of the motor 201, and there is no contact between the eccentric mass 202 and the base 2012 of the motor 201.

[0084] In this way, when the connecting member 42 drives the installation mechanism 30 to move, the force acts directly on the connecting seat 31 until the connecting seat 31 abuts against the limit member 45. Then the first mounting seat 32 and the second mounting seat 33 can be smoothly transported to the riveting area, and the positions of the first mounting seat 32 and the second mounting seat 33 can be easily adjusted, which has strong applicability.

[0085] Specifically, in this embodiment, please refer to Figures 1 to 4 、 Figure 8 The connecting seat 31 has a recessed receiving groove 311 on the side away from the base 12. The first mounting seat 32 includes a first mounting plate 321 extending along the first direction. The first mounting plate 321 has a first mounting groove 322 for placing the eccentric block 202 on one end away from the base 12. The second mounting seat 33 can be lifted and lowered on the first mounting plate 321 and has a recessed second mounting groove 331 for placing the motor 201 on the side away from the base 12. The first mounting groove 322 is coaxial with the second mounting groove 331.

[0086] A fixed magnet 34 is disposed within the second mounting base 33. One end of the fixed magnet 34 is exposed from the second mounting base 33 and is flush with the bottom wall of the second mounting slot 331, thereby securing the motor 201 and preventing it from moving. To ensure that the pressing member 52 can smoothly remove the motor 201 from the second mounting slot 331, the force between the connecting magnet 521 on the pressing member 52 and the motor 201 should be greater than the force between the motor 201 and the fixed magnet 34 within the second mounting base 33. This can be achieved by, but is not limited to, using magnets of different sizes.

[0087] The second mounting base 33 can be connected to fixing holes at different positions on the first mounting plate 321 by screws to achieve lifting. It is understood that in other embodiments of the present application, the second mounting base 33 can also be slidably connected to the first mounting plate 321 and fixed by fasteners such as fixing bolts, but is not limited thereto.

[0088] For further information, please refer to Figures 1 to 4 、 Figure 8 The mounting mechanism 30 also includes a second mounting plate 35 and a stop plate 36 extending along the first direction and disposed on opposite sides of the first mounting plate 321. Opposite sides of the second mounting plate 35 are respectively attached to the first mounting plate 321 and the second mounting seat 33. The second mounting plate 35 has a predetermined thickness to provide a predetermined distance between the base 2012 of the motor 201 and the eccentric mass 202. This distance between the base 2012 and the eccentric mass 202 can be adjusted by replacing second mounting plates 35 of different thicknesses. A third mounting groove 351 is defined at the end of the second mounting plate 35 facing away from the base 12. The radius of the third mounting groove 351 is smaller than that of the first mounting groove 322. The motor shaft 2011 of the motor 201 passes through the third mounting groove 351 and the eccentric mass 202. Thus, the third mounting groove 351 also serves to limit the eccentric mass 202.

[0089] It is understood that the stop plate 36 and the second mounting plate 35 are arranged opposite and parallel to each other, and both limit the eccentric mass 202. In this embodiment, a clearance notch is provided on the stop plate 36 to allow the motor shaft 2011 of the motor 201 to pass through. The size of the clearance notch and the size of the third mounting groove 351 are both smaller than the size of the first mounting groove 322. It is understood that in other embodiments of the present application, the clearance notch may be omitted, and the stop plate 36 may be a plastic plate with a certain degree of deformability.

[0090] Among them, the first mounting seat 32 also includes a third mounting plate (not shown) that is bent and connected to the first mounting plate 321. The third mounting plate fits the bottom wall of the accommodating groove 311 and can be fixedly connected by screws, that is, the first mounting seat 32 is L-shaped as a whole. This structural design can enhance the connection between the first mounting seat 32 and the connecting seat 31, and the structure is stable.

[0091] In one embodiment, the operation process of the riveting device 100 includes:

[0092] First, please refer to Figures 2 to 4 The operator places the motor 201 and the eccentric block 202 on the mounting mechanism 30 outside the riveting area. After the placement is completed, the operator activates the switch to start the control program, and the driving member 41 starts to work and its driving shaft extends along the second direction.

[0093] Then, the extension of the drive shaft drives the connecting member 42 forward, pushing the elastic member 46 forward. This pushes the mounting mechanism 30 forward as well. Because the connecting member 42 is fixedly connected to the rack 44, the rack 44 also moves forward synchronously. Because the rack 44 of the mounting mechanism 30 can only move forward within the guidance of the left and right pressure plates 66, the strip-shaped holes 61 designed in the connecting seat 31 allow for a relative movement distance from the rack 44. As the rack 44 continues to move forward, the strip-shaped holes 61 in the connecting seat 31 function to prevent the mounting mechanism 30 from moving. At this point, the rack 44 continues to move forward under the forward movement of the driving member 41, driving the gear 43 to rotate. Simultaneously, the clamping member 53 fixed to the gear shaft 431 also rotates synchronously with the gear 43. When the driving member 41 pushes the rack 44 forward, driving the mounting mechanism 30 forward, and its forward movement is limited by the stopper 45, the mounting mechanism 30 stops moving forward and remains below the rivet head 20, i.e., in the riveting area.

[0094] Secondly, under the action of the driving member 41, although the installation mechanism 30 no longer moves forward and stays below the rivet head 20, the driving member 41 and the rack 44 continue to move forward, and the pressing member 52 also continues to press down. This travel action is achieved by using the elastic member 46 placed between the connecting member 42 connected to the driving member 41 and the installation mechanism 30, which can be compressed. The driving member 41 continues to move forward, pushing the rack 44 forward at the same time, until the rack 44 is pushed to abut against the limit column 47 and cannot move further, that is, Figure 5 In the state shown, the position at this time is that the pressing member 52 presses the motor 201, and the rivet head 20 rivets the eccentric block 202 downward, and the riveting is completed.

[0095] Secondly, after the motor 201 and the eccentric block 202 are riveted together, because the motor 201 is fixed in the second mounting groove 331 of the second mounting seat 33 and is attracted by the connecting magnet 521, in order to be able to remove it smoothly, the second mounting seat 33 needs to be stationary first, and the connecting magnet 521 on the pressing member 52 attracts the motor 201, that is, Figure 6 As shown. At this time, the driving member 41 is moving back, and at the same time, it drives the rack 44 and the connecting member 42 to move back. At this time, the bar-shaped hole 61 on the mounting mechanism 30 plays a role, which can ensure that the driving member 41, the rack 44, the gear 43, and the pressing member 52 are all moving respectively, so that the pressing member 52 can first remove the riveted workpiece, that is, the motor 201 is removed from the second mounting seat 33. After the pressing member 52 removes the motor 201, the adjustment distance of the bar-shaped hole 61 on the connecting seat 31 is completed, and then the connecting seat 31 also moves together with the rack 44 under the drive of the driving member 41. When the connecting magnet 521 attracts the motor 201 and rotates to the stripping plate 51 with the pressing member 52, that is, Figure 8 As shown, because the clearance groove 54 on the stripper plate 51 can only allow the clamping member 52 to pass through, the riveted workpiece will be separated from the clamping member 52 after it hits the stripper plate 51, causing the motor 201 to disengage the clamping member 52, thereby achieving the purpose of disengaging the material distribution. At this time, the riveted workpiece slides to the bottom along the stripper plate 51 due to gravity, and the remaining parts also make corresponding movements until the travel of the driving member 41 is completed, each part is reset, and the second mounting seat 33 completely leaves the riveting area. The operator can then place the motor 201 and the eccentric block 202 in a safe area. Because of the second mounting plate 35, the gap between the base 2012 of the motor 201 and the eccentric block 202 will not change. In addition, there is a limit plate 36 on the other side of the first mounting plate 321, and the eccentric block 202 is restricted from moving, which can control the product quality. After placement is completed, the operator activates the switch to start the control program and start the next cycle.

[0096] The riveting device 100 can drive the installation mechanism 30 via the conveying mechanism 40 to deliver the motor 201 and the eccentric weight 202 to the riveting area. Since the motor 201 and the eccentric weight 202 can be manually placed in advance outside the riveting area, this can avoid safety accidents that may occur due to accidental contact or machine failure when the operator manually places the motor 201 and the eccentric weight 202 in the riveting area, thereby improving safety. In addition, the riveting device 100 can achieve automation of the loading, riveting, and unloading processes through the coordinated operation of the installation mechanism 30, the conveying mechanism 40, and the unloading mechanism 50, thereby saving labor costs and improving production efficiency.
