For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0078] As Figure 1-6 shown, the present invention provides a roller riveting device, including:

[0079] The base 100 is arranged at the place of use as required; in the present invention, 4 legs are further arranged at the lower part of the base 100, and the base 100 is supported by the legs; the legs can be made of rubber material, which can buffer the force generated during operation; at the same time, suction cups or the like can be arranged at the bottom of the legs; during the use stage, the suction cups are used to adsorb to the place of use to improve the stability during the overall operation;

[0080] An installation plate 200 is vertically arranged on the base 100. The installation plate 200 includes a first installation surface 201 and a second installation surface 202; in addition, a vertical plate 902 is arranged between the base 100 and the installation plate 200 to increase the stability of the installation plate 200. Preferably, vertical plates 902 are arranged on both sides of the installation plate 200;

[0081] The workpiece placement mechanism 300 is arranged on the first mounting surface 201; the positioning mechanism 400 is arranged on the base 100; when the connector 903 is placed on the workpiece placement mechanism 300, the positioning mechanism 400 presses the connector 903 onto the workpiece placement mechanism 300; a plurality of riveting mechanisms 500 are arranged on the first mounting surface 201 and are arranged around the workpiece placement mechanism 300; wherein, a wheel set 600 is arranged at one end of the riveting mechanism 500 adjacent to the workpiece placement mechanism 300; in the use state, a plurality of riveting mechanisms 500 move on the first mounting surface 201 and drive the wheel set 600 to move along an arc to flatten the elastic piece of the connector 903 placed on the workpiece placement mechanism 300; in the present invention, the movement sequence of a plurality of riveting mechanisms 500 can be set according to needs to improve the overall adaptability. Preferably, a riveting mechanism 500 is arranged on each of the four sides of the workpiece placement mechanism 300, and the four sides of the connector 903 placed on the workpiece placement mechanism 300 are respectively riveted.

[0082] The technical solution of the present invention forms an overall support structure through the cooperation of the base 100 and the mounting plate 200, and the workpiece placement mechanism 300 is arranged on the mounting plate 200. An operator places the buckled connector 903 on the workpiece placement mechanism 300, and the positioning mechanism 400 presses the connector 903 to prevent the connector 903 from displacing on the workpiece placement mechanism 300. The actions of a plurality of riveting mechanisms 500 use the wheel sets 600 on the plurality of riveting mechanisms 500 to rivet the elastic pieces at different positions of the connector 903 placed on the workpiece placement mechanism 300, improving the accuracy and efficiency of riveting; in addition, when riveting is performed by the riveting mechanism 500, the contact between the wheel set 600 and the elastic piece reduces the friction force generated on the connector 903, thereby reducing the damage to the connector 903; compared with the prior art, the technical solution of the present invention is reasonable, can improve the accuracy of the elastic piece riveting of the connector 903 while reducing labor costs, and at the same time avoid problems such as elastic piece deformation caused by uneven force during manual operation.

[0083] Such as Figure 3As shown, the workpiece placement mechanism 300 includes a fixed table 301 and a profiling block 302. The fixed table 301 is arranged on the first mounting surface 201; the profiling block 302 is arranged on the fixed table 301 and fixed by a first pressing plate 303. In the present invention, the fixed table 301 is fixed to the mounting plate 200 by bolts, and after fixing, the fixed table 301 is placed on the first mounting surface 201. At the same time, a groove is provided on the fixed table 301, and the profiling block 302 is arranged and fixed in the groove on the fixed table 301, and then the profiling block 302 is further pressed by the first pressing plate 303. It should be noted that the profiling block 302 has the same internal shape as the connector 903, which can ensure the stability of the connector 903 after being placed on the profiling block 302. At the same time, when riveting the connector 903, the profiling block 302 supports the inside of the connector 903 to prevent the connector 903 from being overly deformed during the riveting process. It should be noted that for different connectors 903, the profiling block 302 can be replaced according to the specific actual situation, and the present invention will not further limit it.

[0084] As Figure 1 shown, the positioning mechanism 400 includes a driving device 401 and a positioning arm 402. The driving device 401 is vertically arranged on the base 100; the positioning arm 402 is arranged on the driving device 401 and moves in the vertical direction under the drive of the driving device 401. When the connector 903 is placed on the workpiece placement mechanism 300, the driving device 401 drives the positioning arm 402 to move and presses the connector 903 onto the workpiece placement mechanism 300. In the present invention, preferably, the driving device 401 is a cylinder and is connected to the air source through an air pipe (not shown in the figure). Since the air pipe and the air source are prior arts, the present invention will not further describe them. After the connector 903 is placed on the workpiece placement mechanism 300, the driving device 401 drives the positioning arm 402 to act, so that the positioning arm 402 contacts the connector placed on the workpiece placement mechanism 300 and applies a pressing force to the connector 903 to ensure that the connector 903 will not be displaced on the workpiece placement mechanism 300.

[0085] As Figure 5As described above, the riveting mechanism 500 includes a first driving group 501, a second driving group 502, and a third driving group 503. Specifically, the first driving group 501 is disposed on the first mounting surface 201, the second driving group 502 is disposed on the first driving group 501, and the third driving group 503 is disposed on the second driving group 502. The wheel group 600 is disposed on the third driving group 503. In the use state, the second driving group 502 and the third driving group 503 act simultaneously, and drive the wheel group 600 to move along an arc to flatten the elastic piece of the connector 903 placed on the workpiece placing mechanism 300. In the actual use stage, after the position is adjusted by the first driving group 501, the second driving group 502 and the third driving group 503 can act; or the first driving group 501, the second driving group 502, and the third driving group 503 can act simultaneously, so as to realize the riveting of the connector 903 after the wheel group 600 moves along an arc.

[0086] Among them, the first driving group 501 includes a first fixing seat 511, a first actuating device 512, and a first moving plate 513. The first fixing seat 511 is disposed on the first mounting surface 201. The first actuating device 512 is inserted through the first fixing seat 511. The first moving plate 513 is connected to the first actuating device 512 through a first joint 514. And the first moving plate 513 is disposed on a first slide rail 515 on the first mounting surface 201. When in use, the first actuating device 512 pushes the first moving plate 513 to perform a linear motion on the first slide rail 515, thereby driving the second driving group 502 and the third driving group 503 to perform a linear motion simultaneously following the first moving plate 513, so that the second driving group 502 and the third driving group 503 move closer to the connector 903 on the workpiece placing mechanism 300.

[0087] The second driving group 502 includes a second actuating device 521 and a second moving plate 522. The second actuating device 521 is inserted through the first moving plate 513. The second moving plate 522 is connected to the second actuating device 521 through a second joint 523. And the second moving plate 522 is disposed on a second slide rail 524 on the first moving plate 513. After the first driving group 501 is adjusted or when the first driving group 501 acts, the second actuating device 521 pushes the second moving plate 522 to perform a linear motion on the second slide rail 524.

[0088] The third driving group 503 includes a second fixed seat 531, a third actuating device 532, and a third moving plate 533. The second fixed seat 531 is disposed on the second moving plate 522; the third actuating device 532 is disposed on the second fixed seat 531; the third moving plate 533 is connected to the third actuating device 532 through a third joint 534, and the third moving plate 533 is disposed on a third slide rail 535 on the second fixed seat 531; while the second driving group 502 is operating, the third actuating device 532 pushes the third moving plate 533 to perform a linear motion on the third slide rail 535. Since the wheel set 600 is disposed on the third moving plate 533, during the movement of the third moving plate 533, the wheel set 600 contacts the connector 903, and under the action of the third moving plate 533, the elastic piece on the connector 903 is flattened; in the present invention, to ensure the stability of the second fixed seat 531, a reinforcing plate 536 is preferably provided. The reinforcing plate 536 is disposed at the connection between the second fixed seat 531 and the second moving plate 522, and there are two reinforcing plates 536, which are oppositely disposed at the connection between the second moving plate 522 and the second fixed seat 531.

[0089] In the present invention, the first moving plate 513 and the third moving plate 533 perform lateral movements, and the second moving plate 522 performs a vertical movement; and the third moving plate 533 and the second moving plate 522 act simultaneously, so that the wheel set 600 on the third moving plate 533 moves on an arc from bottom to top; and during the movement, it contacts the elastic piece on the connector 903 and flattens the contacted elastic piece; in the present invention, preferably, the first actuating device 512, the second actuating device 521, and the third actuating device 532 are all air cylinders.

[0090] It should be noted that the four riveting mechanisms 500 in the present invention have the same structure. The two riveting mechanisms 500 arranged up and down are mirror images of each other, and the riveting mechanisms arranged left and right are also mirror images of each other; the difference is that for different connectors 903, the number of rollers in the wheel set 600 on the riveting mechanism 500 is different. The specific number of rollers is subject to the actual connector 903 to be riveted, and the present invention will not further limit it.

[0091] As Figure 5 shown, the present invention further includes a first shaping mechanism 701 and a second shaping mechanism 702; the first shaping mechanism 701 and the second shaping mechanism 702 are oppositely disposed on the first mounting surface 201 and are placed on both sides of the workpiece placing mechanism 300; specifically, the first shaping mechanism 701 and the second shaping mechanism 702 are vertically disposed on both sides of the workpiece placing mechanism 300; and after the riveting mechanism 500 rivets the connector 903, they act simultaneously to adjust the riveted connector 903; ensuring the flatness of the upper and lower surfaces of the connector 903.

[0092] Among them, the first shaping mechanism 701 includes a third fixed seat 711, a mounting body 712, a fourth actuating device 713 and a limiting group 718. The third fixed seat 711 is arranged on the first mounting surface 201; the mounting body 712 is arranged on the third fixed seat 711; the fourth actuating device 713 is arranged on the mounting body 712 and is connected to a second pressing plate 717 inside a slider 716 arranged on the mounting body 712 through a fourth joint 715; the limiting group 718 is arranged on the second pressing plate 717; after the over-riveting mechanism 500 finishes riveting the connector 903, the fourth actuating device 713 drives the second pressing plate 717 to perform a linear motion inside the slider 716, and simultaneously drives the limiting group 718 to act through the second pressing plate 717. The limiting group 718 contacts one surface of the connector 903 and adjusts the flatness of this surface.

[0093] In addition, the mounting body 712 includes a first plate body 721 and a second plate body 722, and the first plate body 721 is vertically connected to the second plate body 722; the first plate body 721 is arranged on the third fixed seat 711, and the slider 716 is arranged on the first plate body 721; the fourth actuating device 713 is arranged on the second plate body 722, and the output shaft of the fourth actuating device 713 passes through the second plate body 722 and is connected to the second pressing plate 717 through a fourth joint 715; through the arrangement of the first plate body 721 and the second plate body 722, the output shaft of the fourth actuating device 713 can be higher than the first plate body, so that the connection between the fourth actuating device 713 and the second pressing plate 717 can be better realized, and the second pressing plate 717 can be driven to perform a linear motion inside the slider 716.

[0094] The limiting group 718 includes a first connecting block 781, a second connecting block 782, a first limiting plate 783, a second limiting plate 784 and a plurality of finishing blocks 785. The first connecting block 781 is connected to the second pressing plate 717; the second connecting block 782 is connected to the first connecting block 781; the first limiting plate 783 and the second limiting plate 784 are relatively arranged and penetrate through the second connecting block 782; a plurality of finishing blocks 785 are arranged on the second connecting block 782 and are placed between the first limiting plate 783 and the second limiting plate 784; under the drive of the second pressing plate 717, the plurality of finishing blocks 785 contact the connector 903 and adjust the flatness of the connector 903; during the flatness adjustment process, the first limiting plate 783 and the second limiting plate 784 limit the movement distance of the plurality of finishing blocks 785 to prevent the plurality of finishing blocks 785 from over-adjusting the connector 903; preferably, 4 finishing blocks 785 are provided, and the number and distance between the finishing blocks 785 can be adjusted according to needs, specifically subject to the actual situation, and the present invention will not be further limited.

[0095] Specifically, a first movable slot and a second movable slot are oppositely arranged on the second connection block 782; the first limiting plate 783 and the second limiting plate 784 are respectively arranged in the first movable slot and the second movable slot, and protrusions are oppositely arranged on both sides of one end of the first limiting plate 783 and the second limiting plate 784 placed in the first movable slot and the second movable slot for limiting, so as to prevent the first limiting plate 783 and the second limiting plate 784 from falling off the first movable slot and the second movable slot respectively; when the first connection block 781 and the second connection block 782 are fixed, the moving distances of the first limiting plate 783 and the second limiting plate 784 are blocked by the first connection block 781; at the same time, return springs are arranged between the first limiting plate 783 and the second limiting plate 784 and the first connection block 781; during actual operation, the first limiting plate 783 and the second limiting plate 784 contact the connector 903, and as the fourth actuating device 713 continues to act, the first limiting plate 783 and the second limiting plate 784 will retract into the first movable slot and the second movable slot. When compressed to a certain extent, the first limiting plate 783 and the second limiting plate 784 stop being compressed after contacting the first connection block 781 respectively. At this time, the first limiting plate 783 and the second limiting plate 784 are in a static state, realizing the maximum distance limit for the movement of several finishing blocks 785;

[0096] It should be noted that when the first limiting plate 783 and the second limiting plate 784 move towards the position where the first connection block 781 is located, the return springs will be compressed; when the first limiting plate 783 and the second limiting plate 784 are separated from the connector 903, under the action of the return springs, the first limiting plate 783 and the second limiting plate 784 move away from the first connection block 781 to achieve reset; in addition, the second shaping mechanism 702 has the same structure as the first shaping mechanism 701. To save space, the specific structure of the second shaping mechanism 702 will not be further described in the present invention.

[0097] As Figure 6 shown, the present invention further includes a material discharging mechanism 800. The material discharging mechanism 800 is arranged on the second mounting surface 202, and one end passes through the mounting plate 200 and is placed in the material discharging slot 304 in the profiling block 302, and the movement track of one end of the material discharging mechanism 800 in the material discharging slot 304 is restricted by the first pressing plate 303; when the connector 903 is processed by the riveting mechanism 500, the first shaping mechanism 701 and the second shaping mechanism 702, the material discharging mechanism 800 acts and pushes the connector 903 to move a certain distance on the workpiece placing mechanism 300, and the riveted connector 903 is taken off manually, and the next connector 903 is placed on the workpiece placing mechanism 300 for riveting operation.

[0098] Among them, the material discharging mechanism 800 includes a fourth fixed seat 801, a fifth actuating device 802 and a plurality of ejector rods 804.

When discharging materials, the fifth actuating device 802 pushes the fourth moving plate 803 to move horizontally, and the fourth moving plate 803 drives a plurality of ejector rods 804 to move in the material discharging groove 304. When the ejector rod 804 contacts the connector 903, the connector 903 is driven to move on the profiling block 302 to complete the material discharging operation. In the present invention, in order to ensure the stability of the movement of the connector 903 on the profiling block 302, preferably two ejector rods 804 are provided. The two ejector rods 804 are oppositely arranged on the fourth moving plate 803 and move linearly simultaneously with the fourth moving plate 803 under the drive of the fifth actuating device 802. In the present invention, the fifth actuating device 802 is preferably a cylinder. In addition, a protective cover 901 is also arranged on the mounting plate 200 to protect the material discharging mechanism 800 through the protective cover 901 to prevent the outside from contacting the material discharging mechanism 800.

[0099] It should be noted that a controller is also provided in the present invention to control the positioning mechanism 400, a plurality of riveting mechanisms 500, the positioning mechanism 400 and the material discharging mechanism 800 to act respectively. Among them, the controller adopts the prior art, such as a controller including a single-chip microcomputer chip or a PLC control board, etc. Since the prior art is adopted, the present invention will not further describe the controller. In the actual installation stage, the controller can be fixed in the installation box 904 to protect the controller through the installation box 904.
