Technical Field

[0001] This utility model relates to the technical field of riveting machines, specifically to an automatic double riveting machine for picture frame back panels. Background Technology

[0002] During the production of picture frame back panels, hooks and other hardware need to be installed on the back panels. There are many types of hardware; some hardware needs to be riveted to the picture frame back panel with individual rivets, while others have their own riveting structure.

[0003] When designing for automation, separate feeding mechanisms for the picture frame back panels and hardware components need to be set up. Hardware components can be fed via a vibratory feeder and its associated rails. The same type of hardware component can typically be adapted to various sizes of picture frame back panels, usually eliminating the need to consider the compatibility of the vibratory feeder and its rails with different hardware components. However, for picture frame back panels of different sizes, when using the same type of hardware, the design of the conveyor mechanism for the picture frame back panels needs to consider its compatibility with different sizes of picture frame back panels.

The hardware feeding mechanisms are used to transport the hardware parts one by one to the corresponding hardware loading station. A backplate conveying mechanism is used to convey a horizontally placed backplate and pass it through a riveting station. Two stamping mechanisms are respectively located in the two riveting stations. The stamping mechanism is used to grab the hardware at the hardware feeding station corresponding to the riveting station and rivet the hardware to the back plate at the riveting station. The backplate conveying mechanism includes a drive unit and two conveying tracks. The conveying tracks are horizontally arranged on the frame and are parallel to each other. The two conveying tracks are spaced apart along a first direction, which is horizontal and perpendicular to the length of the track. The riveting station is located between the two conveying tracks and is spaced apart along the length of the conveying track. Of the two conveying tracks, one of the conveying tracks can move relative to the frame along the first direction, while the other conveying track is fixed. The driving component is located between the two conveying tracks. The driving component can move along the length of the conveying tracks to drive the back plate supported on the two conveying tracks to move along the length of the conveying tracks. The driving component can also move relative to the frame in a first direction. The movable conveying tracks and the driving component are connected by a linkage structure. When the movable conveying tracks move, the driving component is driven to move through the linkage structure so that the distance between the driving component and the two conveying tracks in the first direction remains the same.

[0006] Preferably, the linkage structure includes a linkage block disposed on the frame. The linkage block is movable relative to the frame along the length direction of the conveying track and in a first direction. The linkage block and the two conveying tracks are respectively connected by linkage rods. The linkage rods are horizontally arranged, and their two ends are rotatably connected to the linkage block and the conveying track, respectively. The rotation axis is vertical. The two linkage rods are of the same length and form the same angle with the length direction of the conveying track.

The driving block moves along the direction in which the height of the guide slope gradually decreases until it contacts the back plate supported on the two conveying tracks, at which point the back plate contacts the guide slope.

[0008] Preferably, there are two driving components, which are spaced apart along the length of the conveying track, and each driving component can move independently along the length of the conveying track.

[0009] Preferably, the frame is further provided with a back plate loading station, which is located between the two conveying tracks, and the back plate loading station and the riveting station are distributed at intervals along the length of the conveying tracks; The backplate loading station is equipped with a backplate feeding mechanism, which is used to place the backplates one by one on the two conveying tracks.

[0010] Preferably, the backplate feeding mechanism includes: Two support platforms are respectively disposed on two conveying tracks. The support platforms are located above the conveying tracks. The two support platforms cooperate with each other to support a back plate that is horizontally arranged and stacked from bottom to top. Each of the two support platforms is provided with a pushing component. The pushing component on each support platform is used to drive the bottommost back plate to move along a first direction until it is detached from the support platform.

One of the material stoppers is spaced apart from the support surface of the support platform below, and the distance between them is greater than the thickness of a single back plate but less than the sum of the thicknesses of the two back plates.

[0012] Preferably, the material stop includes a baffle, which is vertical and parallel to the length direction of the conveying track.

[0013] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: This application utilizes a hardware feeding mechanism to supply hardware to the hardware loading station, a backplate conveying mechanism to transport the backplate through the riveting station, a stamping mechanism to grip the hardware at the hardware loading station, and a riveting mechanism to rivet the hardware onto the backplate at the riveting station, thus automating the riveting process. Two riveting mechanisms can perform riveting simultaneously, improving processing efficiency. The backplate conveying mechanism employs two conveyor tracks and a drive component. The conveyor tracks support the backplate, and the drive component moves the backplate for transport. One of the conveyor tracks is movable, allowing for adjustable spacing between the two tracks. This spacing can be adjusted according to different backplate specifications to ensure stable support and transport of the backplate. The distance between the drive component and the two conveyor tracks adjusts synchronously with the adjustment of the track spacing, ensuring that the distance between the drive component and the two conveyor tracks remains constant in the first direction. The drive component always remains between the two conveyor tracks, and when moving, it drives the backplate from the center, ensuring stable transport of the backplate. Attached Figure Description

[0021] Reference Figure 1 As shown, this application provides an automatic double riveting machine for picture frame back panels, including a frame 1 and a hardware feeding mechanism 2, a back panel conveying mechanism 3, and a stamping mechanism 4 disposed on the frame 1. The frame 1 is provided with a riveting station 11 and a hardware loading station 12. The hardware feeding mechanism 2 is used to convey hardware parts one by one to the hardware loading station 12. The back panel conveying mechanism 3 is used to convey the horizontally placed back panel and make the back panel pass through the riveting station 11. The stamping mechanism 4 is disposed in the riveting station 11 and is used to grab the hardware parts at the hardware loading station 12 and rivet the hardware parts to the back panel at the riveting station 11.

[0022] Reference Figure 1 and Figure 2 As shown, the frame 1 includes a horizontally arranged operating table 13, a riveting station 11 and a hardware loading station 12, which are distributed at intervals on the surface of the operating table 13.

[0023] Reference Figure 1 and Figure 3 As shown, the hardware feeding mechanism 2 includes a vibratory feeder 21 and a guide rail 22 adapted to the hardware. The hardware output from the vibratory feeder 21 is sequentially conveyed to the hardware loading station 12 along the guide rail 22. In this embodiment, the hardware has a built-in riveting shaft. The hardware is output from the guide rail 22 with the riveting shaft vertical and facing downwards.

[0024] Reference Figure 3 As shown, specifically, a hardware part positioning gripper 23 is provided at the hardware part loading station 12. The two fingers of the positioning gripper move horizontally, and a positioning groove adapted to the hardware part is provided between the two fingers, so that the hardware part maintains a vertical and downward orientation of the riveting shaft when gripped by the positioning gripper. The hardware part loading station 12 specifically includes receiving positions and waiting positions distributed horizontally. The positioning gripper can reciprocate between the receiving position and the waiting position. Hardware parts output from the hardware part guide rail 22 arrive at the receiving position to wait for the positioning gripper to receive them. The positioning gripper moves to the receiving position to receive and clamp the hardware part, and then moves to the waiting position to wait for the stamping mechanism 4 to grab the hardware part. The reciprocating movement of the positioning gripper between the receiving position and the waiting position can be achieved by a cylinder drive, and a linear module is set for guidance and limitation. Thus, the function of feeding hardware parts one by one to the waiting position to wait for the stamping mechanism 4 to grab is realized, that is, the automatic loading of hardware parts is achieved.

[0025] Reference Figure 1 and Figure 4 As shown, the stamping mechanism 4 includes a punch 41 and a stamping drive mechanism. The punch 41 can be vertically raised and lowered, and can also move horizontally back and forth between the riveting station 11 and the hardware loading station 12, specifically, it can move horizontally back and forth between the riveting station 11 and the waiting position. The stamping drive mechanism is used to drive the punch 41 to be raised, lowered, and moved horizontally.

[0026] Reference Figure 4 As shown, specifically, the punch 41 is configured with a magnetic head at the lower end, using magnetic force to grip the hardware at the desired position. A lower support column 42 is provided on the frame 1 at the riveting station 11. When the back plate is conveyed to the riveting station 11, it is positioned above the lower support column 42. The punch 41 can move above the lower support column 42, so that by descending the punch 41 and engaging with the lower support column 42, the hardware is riveted to the back plate.

[0027] The stamping drive mechanism can employ a combination of a cylinder and an electric lead screw mechanism. The cylinder drives the punch 41 to rise and fall, achieving the stamping action of the punch 41. The punch 41 and the cylinder are mounted on the slider of the electric lead screw mechanism, which drives the punch 41 to move horizontally, realizing the function of horizontal reciprocating movement of the stamping head between the riveting station 11 and the waiting position. A corresponding linear module is also provided to guide and limit the movement of the punch 41.

[0028] Reference Figure 1 and Figure 5 As shown, the back panel conveying mechanism 3 includes a drive assembly and two conveying tracks 31. The conveying tracks 31 are horizontally arranged on the frame 1. The two conveying tracks 31 are parallel to each other and are spaced apart along a horizontal direction perpendicular to the track length. The riveting station 11 is located between the two conveying tracks 31. The drive assembly is used to drive the back panel supported on the two conveying tracks 31 to move along the length direction of the conveying tracks 31.

[0029] Reference Figure 5 As shown, the top of the conveying track 31 is provided with a horizontal track surface, the back plate is supported on the track surface, and a cover plate 311 is provided on the top of the conveying track 31. The cover plate 311 is above the track surface and spaced apart from the track surface. When the back plate is supported on the conveying track 31, it is located between the cover plate 311 and the support surface 621 to limit the range of up and down movement of the back plate and improve the conveying stability of the back plate.

[0030] Reference Figure 5 As shown, the drive assembly includes a drive member located between two conveying tracks 31. The drive member can move along the length of the conveying tracks 31 to drive the back plate supported on the two conveying tracks 31 to move.

[0031] Reference Figure 5 As shown, specifically, the driving component includes a driving block 32, the highest point of which is higher than the bottom surface of the back plate supported on the two conveying tracks 31, so that when the driving block 32 moves from one end of the conveying track 31 to the other end, it can abut against the back plate supported on the two conveying tracks 31, thereby driving the back plate to move in that direction.

[0032] Reference Figure 5 and Figure 6 As shown, the top of the drive block 32 is provided with a guide slope 321. In the length direction of the conveying track 31, the height of the guide slope 321 gradually decreases from one end to the other. The height of the highest point of the guide slope 321 is higher than the height of the bottom surface of the back plate supported on the two conveying tracks 31, and the highest point of the guide slope 321 is the highest point of the drive block 32. The drive block 32 moves in the direction where the height of the guide slope 321 gradually decreases until it contacts the back plate supported on the two conveying tracks 31, at which point the back plate contacts the guide slope 321.

[0033] Specifically, the drive block 32 is configured as a vertical surface on one side of the conveying track 31 along its length. The top of this vertical surface connects to the highest point of the guide slope 321 via a horizontal plane. As the drive block 32 moves in the direction where the height of the slope gradually increases, the vertical surface and the back plate abut against each other, thereby driving the back plate to move. The drive block 32 moves in the direction where the height of the guide slope 321 gradually decreases until it contacts the back plate supported on the two conveying tracks 31. At this point, under the guiding action of the guide slope 321, the back plate is driven to move upward by a small amplitude. The drive block 32 lifts the back plate and moves from below the back plate until it passes over the back plate.

[0034] The two ends of the conveyor track 31 are designated as the upstream end and the downstream end, respectively. With the highest point of the guide slope 321 close to the downstream end, the stroke of the drive block 32 moving from the upstream end to the downstream end of the conveyor track 31 is the conveying stroke, and the stroke moving from the downstream end to the upstream end of the conveyor track 31 is the return stroke. During the conveying stroke, the drive block 32 can drive the back plate to move, while during the return stroke, it will not drive the back plate to move. During the process of the drive block 32 driving a back plate to the riveting station 11, subsequent back plates can be directly fed onto the conveyor track 31 without waiting for the drive block 32 to return and reset, thereby realizing continuous feeding of back plates and improving efficiency.

[0035] Reference Figure 5 As shown, two drive blocks 32 are arranged and spaced apart along the length of the conveying track 31. The two drive blocks 32 can move independently along the length of the conveying track 31. The two drive blocks 32 operate separately, driving the movement of two adjacent back plates distributed along the length of the track, avoiding the downstream back plate from obstructing the movement of the upstream back plate, and ensuring the smooth and continuous conveying of the back plates.

[0036] Reference Figure 5 As shown, the movement of the drive block 32 is achieved through a belt mechanism driven by a motor. Specifically, a drive frame 33 is set on the bottom surface of the operating table 13. A linear module along the length of the conveyor track 31 is mounted on the drive frame 33 to guide and limit the movement of the drive block 32. The drive block 32 is mounted on the slider of the linear module through a mounting frame 34 passing through the operating table 13. The belt mechanism is mounted on the drive frame 33. The mounting frame 34 is fixedly connected to the belt in the belt mechanism through a connecting block, so that when the belt rotates, it drives the mounting frame 34 and the drive block 32 to move, realizing the function of the drive block 32 moving along the length of the conveyor track 31.

[0037] Specifically, the two drive blocks 32 are equipped with motors and belt mechanisms respectively to achieve independent operation.

[0038] Reference Figure 7As shown, further, in order to adapt the back panel conveying mechanism 3 to the conveying requirements of back panels of different specifications, the distance between the two conveying tracks 31 is adjustable. Specifically, one of the conveying tracks 31 can move relative to the frame 1 along the first direction, while the other conveying track 31 is fixed.

[0039] The movable track is movably installed on the operating table 13 via a linear module, and the conveying track 31 is moved by an electric screw mechanism to achieve electric adjustment of the distance between the two conveying tracks 31.

[0040] Furthermore, the drive component is designed to move relative to the frame 1 in the first direction. The movable conveyor track 31 and the drive component are connected by a linkage structure 5. When the movable conveyor track 31 moves, it drives the drive component to move through the linkage structure 5, ensuring that the distance between the drive component and the two conveyor tracks 31 remains the same in the first direction. This arrangement ensures that the drive component is always positioned between the two conveyor tracks 31. When the drive component moves, it drives the back plate from the middle, ensuring the stability of the back plate conveying.

[0041] Reference Figure 8 As shown, specifically, in this embodiment, the drive frame 33 is configured to be movable relative to the frame 1 in the first direction. Correspondingly, a linear module along the first direction is provided at the bottom of the operating table 13 for the drive frame 33 to be installed. The movement of the drive frame 33 allows the drive block 32 to move along the first direction.

[0042] Reference Figure 7 As shown, in order to realize the linkage between the drive block 32 and the conveying track 31, the linkage structure 5 includes a linkage block 51. The linkage block 51 is mounted on the frame 1. The linkage block 51 can move relative to the frame 1 along the length direction of the conveying track 31 and the first direction. The linkage block 51 and the two conveying tracks 31 are respectively connected by linkage rods 52. The linkage rods 52 are horizontally arranged. The two ends of the linkage rods 52 are rotatably connected to the linkage block 51 and the conveying track 31 respectively. The rotation axis is vertical. The two linkage rods 52 have the same length and the same angle with the length direction of the conveying track 31. The drive component is connected to the linkage block 51 and is fixed relative to it in the first direction.

[0043] Specifically, the linkage block 51 is installed on the operating table 13. The linkage block 51 is installed on the operating table 13 through two linear modules. One linear module is set along the first direction, and the other linear module is set along the track length direction and installed on the slider of the linear module set along the first direction. The linkage block 51 is installed on the slider of the linear module set along the track length direction.

[0044] Reference Figure 8 As shown, the drive frame 33 is fixed to the track of the linear module arranged along the track length direction by a connecting plate 331, so that the drive frame 33 can move along the linear module in the first direction.

[0045] When the movable conveying track 31 moves, the linkage rod 52 drives the linkage block 51 to move along the length of the track and along the first direction. The drive frame 33 and the drive block 32 move with the linkage block 51 in the first direction. The linkage block 51 always stays in the middle of the two conveying tracks 31, so that the drive block 32 always stays in the middle of the two conveying tracks 31.

[0046] Reference Figure 8 As shown, a fixed cylinder 35 is further provided on the drive frame 33. The piston rod of the fixed cylinder 35 is set vertically upward. After the drive frame 33 moves to the set position with the conveying track 31, the piston rod of the fixed cylinder 35 extends and presses against the bottom surface of the operating table 13 so that the drive frame 33 is kept in the adjusted position.

[0047] Reference Figure 2 and Figure 9 As shown, the frame 1 further includes a backplate loading station 14, located between two conveyor tracks 31. The backplate loading station 14 and the riveting station 11 are spaced apart along the length of the conveyor tracks 31. The backplate loading station 14 is equipped with a backplate feeding mechanism 6, which places the backplates one by one onto the two conveyor tracks 31. This arrangement is for automatic feeding of the backplates onto the conveyor tracks 31.

[0048] Reference Figure 9 and Figure 10 As shown, the backplate feeding mechanism 6 includes two support platforms 61 and a baffle assembly. The two support platforms 61 are respectively mounted on two conveying tracks 31, with the support platforms 61 positioned above the conveying tracks 31. The two support platforms 61 cooperate to support backplates that are horizontally arranged and stacked from bottom to top. Each support platform 61 is equipped with a pushing assembly. The pushing assembly on each support platform 61 is used to drive the bottommost backplate to move along a first direction until it detaches from the support platform 61, and when the backplate detaches from the support platform 61, it falls onto the conveying track 31 on that support platform 61. The baffle assembly is used to restrict the horizontal movement of backplates other than the bottommost backplate.

[0049] The back panels to be loaded are stacked sequentially on two support platforms 61. When it is necessary to load them onto the conveyor rail 31, a pushing component first drives the bottom back panel to move along the first direction until it detaches from the support platform 61. At this time, one side of the bottom back panel falls onto the conveyor rail 31 corresponding to the support platform 61, and the other side of the back panel is supported by another support platform 61. Then, the pushing component on the support platform 61 that is still supporting the back panel is activated to drive the back panel to detach from the support platform 61. The other side of the back panel falls onto the conveyor rail 31 corresponding to the support platform 61. That is, both sides of the back panel fall onto the two conveyor rails 31 respectively, realizing the function of loading the back panels one by one onto the conveyor rail 31.

[0050] Reference Figure 9 and Figure 10 As shown, specifically, the support platform 61 is configured to extend along the length of the conveyor track 31 to stably support the back plate. The support platform 61 is provided with a support surface 621 for supporting the back plate, and a support plate 62 is provided on the side of the two support platforms 61 that are close to each other, with the top of the support plate 62 serving as the support surface 621.

[0051] Reference Figure 9 and Figure 10 As shown, the pushing assembly includes a pushing plate 63 and a driving structure. The pushing plate 63 is horizontally positioned on one side of the two support platforms 61 that are far apart from each other. A pushing groove 611 extending through the support platform 61 in a first direction is provided. The pushing plate 63 passes through the pushing groove 611 and can move along the first direction. It can move to partially pass through the pushing groove 611 and be located on one side of the two support platforms 61 that are close to each other. This allows the pushing plate 63 to drive the back plate supported on the support plate 62 to move away from the support plate 62. Specifically, the pushing plate 63 is attached to the support surface 621 and its thickness is no greater than the thickness of a single back plate, so that when the pushing plate 63 moves, it only pushes the lowermost back plate.

[0052] Reference Figure 10 As shown, the drive structure is used to drive the pusher plate 63 to move along a first direction. It includes a drive base 64 and a drive cylinder. The drive base 64 is located on one side of the two support platforms 61 that are far apart from each other. The drive base 64 is configured to move along the length of the conveying track 31, and the drive cylinder is used to drive the drive base 64 to move along this direction. A drive groove 631 is provided on the pusher plate 63. The two ends of the drive groove 631 are spaced apart in the first direction and are also spaced apart on the conveying track 31. A drive column 65 is connected to the drive base 64 and embedded in the drive groove 631. When the drive base 64 moves, the drive column 65 moves in the drive groove 631. Under the guidance of the drive groove 631, the drive column 65 generates a component force on the pusher plate 63 along the first direction, thereby driving the pusher plate 63 to move along the first direction.

[0053] Reference Figure 9 and Figure 11 As shown, the material-stopping assembly includes two material-stopping members 66, which are respectively disposed on two support platforms 61. The material-stopping members 66 are located above the support platforms 61. A back plate supported on the two support platforms 61 is located between the two material-stopping members 66. Among the back plates supported on the two support platforms 61, except for the lowermost back plate, the movement of the back plates along the first direction is restricted by the two material-stopping members 66. One of the material-stopping members 66 is spaced apart from the support surface 621 of the lower support platform 61, and the distance between them is greater than the thickness of a single back plate but less than the sum of the thicknesses of the two back plates.

[0054] Reference Figure 11 As shown, in this embodiment, of the two baffles 66, one baffle 66 abuts against the support surface 621 of the lower support platform 61, and the support platform 61 is referred to as the first support platform 61. The baffle 66 is provided with a through hole for the pusher plate 63 to pass through. The other baffle is spaced apart from the support surface 621 of the lower support platform 61, and the support platform 61 is referred to as the second support platform 61. Because a gap is provided between the support surface 621 of the second support platform 61 and the stop member 66 thereon, allowing a single backplate to pass through, during loading, the pushing assembly on the first support platform 61 is activated first, pushing the bottommost backplate towards the second support platform 61. This allows the backplate to pass through the gap between the support surface 621 and the stop member 66 of the second support platform 61 until it detaches from the first support platform 61 and falls onto the lower conveyor track 31. Then, the pushing assembly on the second support platform 61 is activated next, pushing the backplate towards the first support until it detaches from the second support platform 61. At this point, the backplate is completely on both conveyor tracks 31, completing the loading of a single backplate. Repeating the above process allows for the loading of backplates one by one.

[0055] In this embodiment, the baffle 66 is a baffle plate, which is vertical and parallel to the length direction of the conveying track 31.

[0056] With the above settings, automatic feeding of hardware parts, automatic feeding of back plates, and automatic stamping can be achieved, thus automating the riveting process.

[0057] Reference Figure 1 and Figure 2 As shown, in this embodiment, there are two riveting stations 11 and two hardware loading stations 12, corresponding to each other. Two hardware feeding mechanisms 2 supply hardware to the two hardware loading stations 12 respectively. The two riveting stations 11 are spaced apart along the length of the conveyor track 31. Correspondingly, two stamping mechanisms 4 are also provided, each located within one of the two riveting stations 11. The punch 41 of each stamping mechanism 4 reciprocates between its respective riveting station 11 and the corresponding hardware loading station 12 to grip the hardware and perform stamping processing. The position of the lower support column 42 in the two stamping mechanisms 4 is determined according to the riveting position of the hardware on the back plate. The two stamping mechanisms can perform stamping processing simultaneously, and the riveting machine can rivet hardware at two locations on the back plate at once, improving processing efficiency.

[0058] Reference Figure 4As shown, in this embodiment, one riveting position on the back plate is located in the middle of the first direction below the back plate. Correspondingly, the lower support column 42 in one of the stamping mechanisms 4 is positioned between the two conveying tracks 31 in the first direction. The lower support column 42 is designed to be connected to the movable conveying track 31 via a linkage structure 5. When the movable conveying track 31 moves, it drives the lower support column 42 to move via the linkage structure 5, ensuring that the distance between the lower support column 42 and the two conveying tracks 31 in the first direction remains constant. The position of the lower support column 42 is adjusted with the conveying track 31, eliminating the need for separate adjustment of the lower support column 42's position.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
