Description

Technical Field

[0001] This invention relates to the field of industrial production equipment technology, and in particular to a double-sided riveting device. Background Technology

[0002] In industrial production, riveting is frequently required for products (such as boxes). For example, in industries like home appliances, machinery, and hardware, small shafts (pins) are often riveted. Riveting is typically done using a riveting machine. Previously, for products requiring double-sided riveting, one side was riveted, the product was flipped over, and then the other side was riveted. This method is time-consuming, labor-intensive, inefficient, and affects riveting accuracy. To address this, double-sided riveting machines have been invented. For instance, Chinese utility model patent CN201520708484.5 discloses a novel double-sided riveting machine that uses a pneumatic-hydraulic booster cylinder to press down, simultaneously moving the upper and lower pressure heads to rivet the workpiece, thus achieving simultaneous, non-discriminatory riveting on both sides of the workpiece and improving production efficiency. However, this double-sided riveting machine is relatively rudimentary and can only handle small, simple products that do not require switching between multiple riveting positions.

[0003] Meanwhile, existing double-sided riveting machines cannot assist in changing rivet heads (die heads). When changing rivet heads, it is necessary to manually remove the entire riveting arm along with the riveting rod (die base), and then take the rivet head from another device for replacement. This is prone to confusion and is not conducive to timely, orderly, and smooth rivet head replacement, resulting in low replacement efficiency.

[0004] Furthermore, traditionally, riveting processes typically involve manual feeding, where the riveted parts are placed manually on the die head, positioned, and then riveted. This traditional feeding method is inefficient and physically demanding for operators. Although automated feeding mechanisms for riveting processes have been invented, current devices cannot properly handle the task of suspending the riveted parts on the guide pin at the top of the riveting head during the lower feeding process. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a double-sided riveting device with a reasonable structural design, high double-sided riveting efficiency, the ability to perform double-sided riveting on various products, and the ability to assist in changing the riveting head.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a double-sided riveting device, comprising a machine body, an electrical control mechanism, a lower riveting mechanism, a lower feeding mechanism, an upper riveting mechanism, an upper feeding mechanism, and a feeding device. The upper and lower riveting mechanisms are vertically opposite each other, the lower riveting mechanism is connected to the lower feeding mechanism, the upper riveting mechanism is connected to the upper feeding mechanism, and the lower and upper feeding mechanisms are respectively connected to the feeding device; the lower riveting mechanism has a lower riveting head, and the upper riveting mechanism has an upper riveting head; a movable support capable of three-dimensional spatial movement is installed on the machine body via a movable guide rail. The mechanism includes a workpiece placed on a movable support mechanism and positioned between an upper and lower riveting head. A riveting head carrying mechanism is installed on the upper feeding mechanism. The riveting head carrying mechanism includes a carrying rod with several slots for placing the riveting heads. The carrying rod is mounted on a carrying bracket, with both sides of the carrying bracket movably mounted on both sides of the upper feeding mechanism, positioning the carrying rod in front of and close to the upper riveting mechanism. A driving component is installed on the upper feeding mechanism and connected to the carrying bracket to drive the carrying rod to move in position.

[0007] This invention, through the coordinated operation of an upper riveting mechanism, a lower riveting mechanism, an upper feeding mechanism, a lower feeding mechanism, and a movable support mechanism for carrying the product workpiece, enables efficient and orderly double-sided riveting of products of various sizes and structural complexities without the need to flip the products, significantly improving riveting efficiency. Simultaneously, the riveting equipment is equipped with a riveting head carrying mechanism, which can hold various commonly used riveting heads for easy replacement, assisting in riveting head changes and ensuring timely, efficient, orderly, and smooth riveting head replacement.

[0008] In addition, for the lower feeding mechanism, by mounting the lower gripper on the Y-axis mechanism, the Y-axis mechanism on the Z-axis mechanism, and the Z-axis mechanism on the X-axis mechanism, and setting a feeding tube to connect the lower gripper to the riveting part feeding device (such as a vibratory feeder), and by setting through-beam sensors (inductors) on both sides of the front end of the lower gripper to detect whether the riveting part is properly hooked, the riveting part can be quickly and accurately conveyed to the lower riveting head of the lower riveting mechanism, and the riveting part is ensured to be hooked on the guide pin at the top of the lower riveting head, thereby achieving efficient and precise lower feeding operation.

Detailed Implementation

[0022] In this embodiment, refer to Figure 1-5 , Figure 10-11The double-sided riveting equipment includes a machine body 1, an electrical control mechanism 9, a lower riveting mechanism 2, a lower feeding mechanism 3, an upper riveting mechanism 5, an upper feeding mechanism 6, and a feeding device. The upper riveting mechanism 5 and the lower riveting mechanism 2 are positioned vertically opposite each other and can simultaneously rivet the workpiece 10 (such as a box) from both the top and bottom. The lower riveting mechanism 2 is connected to the lower feeding mechanism 3, and the upper riveting mechanism 5 is connected to the upper feeding mechanism 6. The lower feeding mechanism 3 and the upper feeding mechanism 6 are respectively connected to the feeding device. The lower riveting mechanism 2 has a lower riveting head 22, and the upper riveting mechanism 5 has an upper riveting head 53. A movable support mechanism 4 capable of three-dimensional spatial movement is installed on the machine body 1 via movable guide rails 12 (in a grid structure in the X-axis and Y-axis directions). After the workpiece 10 is placed on the movable support mechanism 4, it is located between the upper riveting head 53 and the lower riveting head 22. The movable support mechanism 4 can carry the workpiece 10 and perform three-dimensional movements in the forward, backward, left, right, up, and down directions to align the upper riveting head 53 and the lower riveting head 22 for riveting operations. After the upper riveting component is placed on the product 10 at the position where it needs to be riveted, the upper riveting mechanism 5 controls the upper moving head 53 to move downward, thereby riveting the upper riveting component onto the product 10. A riveting head bearing mechanism 7 is installed on the upper feeding mechanism 5. The riveting head bearing mechanism 7 includes a bearing rod 72, which is provided with several placement slots 73 for placing the upper riveting head 53. The bearing rod 72 is mounted on a bearing bracket 71, and the two sides of the bearing bracket 71 are movably mounted on both sides of the upper feeding mechanism 6, so that the bearing rod 72 is located in front of the upper feeding mechanism 6 and close to the upper riveting mechanism 5. A driving component is installed on the upper feeding mechanism 6. The driving component is connected to the bearing bracket 71 to drive the bearing rod 72 to move in position so as to align it with the upper riveting rod 52.

[0023] The upper feeding mechanism 6 includes a mounting frame 64, a plurality of upper grippers 61 (e.g., 12, also known as hinges), and a plurality of vertically penetrating receiving heads 62 (e.g., 12). Each receiving head 62 is connected to a feeding device and installed in a material head rod 63. The material head rod 63 is fixed on the mounting frame 64. Each upper gripper 61 is installed on a gripper plate 65 and located below the material head rod 63. The gripper plate 65 is movably installed on the mounting frame 64 and is connected to a driving mechanism. The driving mechanism drives the gripper plate 65 to move the upper grippers 61 to the required position, thereby placing the upper riveting part on the workpiece 10 at the required riveting position. The mounting frame 65 is movably installed on a linear module 67 to form a structure that can move along the X-axis. The linear module 67 is suspended on two support seats 60. The two support seats 60 are movably installed at both ends of a support rod 68 through a driving device to form a structure that can adjust the height of the linear module 67 vertically.

[0024] The drive device uses an adjusting screw 69 (a cylinder or motor can also be used; when a cylinder or motor is used, the height position of the linear module 67 can be automatically adjusted by driving the support 60). By manually turning the adjusting screw 69, the support 60 can be driven to move up and down, thereby manually adjusting the height position of the linear module 67, and then adjusting the height positions of the upper jaw 61 and the bearing rod 72. This is mainly to accommodate workpieces 10 with different heights.

[0025] The driving mechanism employs a gripper moving cylinder 66. A gripper moving cylinder 66 is connected to each end of the gripper plate 65. The two gripper moving cylinders 66 drive the gripper plate 65, carrying the upper gripper 61, to move along the Y-axis. The driving component connecting the support bracket 71 employs a rivet head changing cylinder 74. The rivet head changing cylinder 74, in conjunction with the linear module 67, drives the support bracket 71, carrying the support rod 72, to move until the rivet head to be replaced aligns with the upper riveting rod 52 of the upper riveting mechanism 5. The upper riveting rod 52 is mounted via the riveting arm 51. The head 53 can be installed at the bottom of the upper riveting rod 52 via a plug-in magnetic attraction method (an electromagnet is installed inside the upper riveting rod 52) or a vacuum adsorption method. First, the upper riveting head 53 at the bottom of the upper riveting rod 52 is manually removed (or the vacuum adsorption is removed, allowing the upper riveting head 53 to fall into the placement groove 73). When the rivet head to be replaced is moved to be aligned with the upper riveting rod 52, the upper riveting rod 52 moves downwards, causing the corresponding rivet head to be inserted into the mounting hole at the bottom of the upper riveting rod 52 and held in place by a magnet or vacuum negative pressure, thus completing the automatic rivet head replacement. A CCD detection device 54 is installed next to the upper riveting rod 52 to inspect the riveting area to ensure that the riveting is qualified.

[0026] The feeding device uses a vibratory feeder 8. The lower feeding mechanism 3 is connected to several vibratory feeders 8 through several conduits, and the upper feeding mechanism 6 is connected to the remaining vibratory feeders 8 through several conduits.

[0027] Specifically, a mounting base 13 is provided at the middle rear part of the machine body 1. The mounting base 13 extends forward and outward above the table surface of the machine body 1. The upper riveting mechanism 5 and the upper feeding mechanism 6 are installed at the top front end of the mounting base 13. An upper support 14 and a lower support 15 are respectively provided on both sides of the mounting base 13. The vibratory feeder 8 connected to the lower feeding mechanism 3 is installed on the lower support 15, and the vibratory feeder 8 connected to the upper feeding mechanism 6 is installed on the upper support 14 to realize separate feeding.

[0028] A protective frame 11 is installed around the platform of the machine body 1, which encloses the mobile support mechanism 4.

[0029] Reference Figure 1 , Figures 6-9Both the lower riveting mechanism 2 and the lower feeding mechanism 3 are mounted on the machine body 1. The lower feeding mechanism 3 includes a lower gripper 31 and a moving mechanism. The lower gripper 31 is mounted on the moving mechanism to hold the riveting parts A (such as rivets, rivet shafts, etc.), and the lower gripper 31 is connected to the riveting part feeding device (such as the vibratory feeder 8). The moving mechanism includes a Y-axis mechanism 33 for forward and backward movement, a Z-axis mechanism 34 for lifting and lowering movement, and an X-axis mechanism 35 for lateral movement. The X-axis mechanism 35 is mounted on... On a support plate 36, a Z-axis mechanism 34 is mounted on an X-axis mechanism 35, and a Y-axis mechanism 33 is mounted on a Z-axis mechanism 34, with the Y-axis mechanism 33 at the highest point of the moving mechanism. A lower gripper 31 is mounted on the front end of the Y-axis mechanism 33, and the Y-axis mechanism 33 carries the lower gripper 31 forward to complete the feeding operation. A sensor 32 is also mounted on the front end of the Y-axis mechanism 33, located on the front side of the lower gripper 31, and the sensor 32 detects the information that the rivet A has been fed into place.

[0030] The Y-axis mechanism 33 includes a Y-axis slide plate 331 and a Y-axis motor 332. A mounting base 311 is fixed on the Y-axis slide plate 331, and the lower gripper 31 is mounted on the mounting base 311 and extends forward.

[0031] A feeding trough 312 is provided on the mounting base 311. The front end of the feeding trough 312 leads to the lower clamping jaw 31. The rivet A is fed into the lower clamping jaw 31 through the feeding trough 312. The tail end of the feeding trough 312 is connected to the rivet feeding device through the feeding pipe 337. For example, the vibratory plate 8 is connected to the feeding pipe 37 through the conduit. The feeding pipe 37 is mounted on the Y-axis slide plate 331.

[0032] A Y-axis guide rail 333 is provided on the bottom surface of the Y-axis slide plate 331. The Y-axis guide rail 333 is mounted on the Z-axis mechanism 34 via a Y-axis slide block 334 to enable forward and backward sliding. A Y-axis motor 332 is installed at the tail of the Y-axis slide plate 331 and is connected to a lead screw. The lead screw is screwed to a lead screw nut installed on the Z-axis mechanism 34. The Y-axis motor 332 drives the lead screw to rotate, thereby driving the Y-axis slide block 334 to move forward and backward, thus enabling the Y-axis slide plate to move forward and backward. Of course, this drive structure itself is prior art and therefore is not shown in detail.

[0033] The Z-axis mechanism 34 includes a Z-axis slide plate 341 and a Z-axis motor 342. A Z-axis guide rail 343 is provided on the back of the Z-axis slide plate 341. The Z-axis guide rail 343 is mounted on the X-axis mechanism 35 via a Z-axis slide block to allow for vertical sliding. A Y-axis slide block 334 is mounted on the top of the Z-axis slide plate 341. The Z-axis motor 342 is mounted on the X-axis mechanism 35 and connected to a gear and rack assembly. The gears of the gear and rack assembly are connected to the Z-axis motor 342, and the rack is fixed to the back of the Z-axis slide plate 341. The Z-axis motor 342 drives the Z-axis slide plate 341 to move vertically via the gear and rack assembly. This drive structure is also prior art and therefore is not illustrated in detail.

[0034] A horizontally oriented X-axis guide rail 361 is mounted on the front side of the support plate 36. The X-axis mechanism 35 is mounted on the X-axis guide rail 361 via a slide block to form a horizontal lateral movement structure.

[0035] The X-axis mechanism 35 includes an X-axis slide plate 351 and an X-axis motor 352. The X-axis slide plate 351 is mounted on the X-axis guide rail 361 via a slide block. The X-axis motor 352 is mounted on a support plate 36, and the Z-axis motor 342 is mounted on the X-axis slide plate 351. The X-axis motor 352 is connected to a gear and rack assembly 353. The gears of the gear and rack assembly 353 are connected to the X-axis motor, and the rack is fixed to the back of the X-axis slide plate 351. The X-axis motor 352 drives the X-axis slide plate 351 to move horizontally through the gear and rack assembly 353. This drive structure, as described for the Z-axis mechanism, is also prior art and therefore is not illustrated in detail.

[0036] Sensor brackets 321 are installed on both sides of the front end of the Y-axis slide plate 331. Sensors 32 are installed on the inner sidewalls of the two sensor brackets 321 respectively. The two sensors 32 form a photosensitive structure, and the lower gripper 31 is located in the range between the two left and right sides.

[0037] The number of lower grippers 31 may be one or more, such as three in this embodiment. When there are multiple lower grippers 31, they are arranged side by side evenly.

[0038] During operation, rivet A is fed into the feed tube 37 via air blowing, and then enters the lower gripper 31 through the feed groove 312. Then, the X-axis mechanism 35, Z-axis mechanism 34, and Y-axis mechanism 33 operate according to positional requirements, causing the lower gripper 31 to move upward and forward above the riveting disc 21 of the lower riveting mechanism 2, aligning it with the lower riveting head 2 on the riveting disc 21 and the guide pin 23 at the top of the lower riveting head 22. Then, the Z-axis mechanism moves the lower gripper 31 slightly downward, allowing rivet A to be hooked onto the guide pin 23. Afterward, the Y-axis mechanism 33 moves the lower gripper 31 slightly backward, and the sensor 32 detects whether rivet A is in place via a photoelectric sensor. Once confirmed to be in place, the X-axis mechanism 35, Z-axis mechanism 34, and Y-axis mechanism 33 retract the lower gripper 31 to its original position, completing one feeding operation. Finally, the movable support mechanism 4 carries the workpiece 10 to the position where it needs to be riveted, aligns with and contacts the guide pin 23, and completes the riveting operation of the riveted part A under the pressing action of the upper riveting head 53.

[0039] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
