DETAILED DESCRIPTION

[0032] The specific embodiments of the present application will be further described below with reference to the drawings. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0033] Combination Figures 1 to 15The automatic hook-and-loop riveting machine shown includes: a machine body 1, with a placement area 2 for placing a photo frame back panel; a lifting device 3 is installed on one side of the inner wall of the placement area 2, which is used to lift the photo frame back panel in the placement area 2 upwards; a photo frame back panel transverse moving device 4 is provided on one side of the upper end of the placement area 2, the photo frame back panel transverse moving device 4 includes a transversely movable negative pressure suction cup 21, which is used to adsorb the upwardly lifted photo frame back panel; a photo frame back panel alignment device 5 is provided on one side of the photo frame back panel transverse moving device 4, so that the photo frame back panel adsorbed and placed on the photo frame back panel alignment device 5 is aligned in position; a multi-axis robot (not shown) is provided on one side of the machine body 1, the multi-axis robot is a six-axis robot, and a negative pressure suction device is installed at the end of the six-axis robot. A six-axis robot arm is positioned near the frame back panel alignment device 5 to adsorb the frame back panel and place it in the designated position. A hook-and-stick stamping device 8 is located on the other side of the frame back panel lateral movement device 4. The six-axis robot arm adsorbs the aligned frame back panel into the hook-and-stick stamping device 8. A hook-and-stick feeding device 6 is located on one side of the hook-and-stick stamping device 8. The hook-and-stick feeding device 6 includes a vibratory feeder 34 and a conveying channel 39. The output end of the vibratory feeder 34 is connected to the conveying channel 39. A vibrator 36 is installed at the lower end of the conveying channel 39 and mounted on a vibrator seat 35. The vibrator seat 35 is mounted on the machine body 1. A hook-and-stick detection sensor 41 is located outside the output end of the conveying channel 39. A hook-and-stick positioning crossbar is located directly below the hook-and-stick detection sensor 41. The moving assembly and hook positioning transverse moving assembly are used to receive the hooks 51 output from the conveying channel 39, and move them laterally after positioning the received hooks 51. A hook feeding device 7 is located on one side of the hook feeding device 6. The hook feeding device 7 includes a hook adsorption assembly 63 that can move back and forth, used to adsorb the laterally moved hooks and move them to the photo frame back panel inside the hook stamping device 8. In this embodiment, the lifting device 3 raises the photo frame back panel in the placement area 2, so that the photo frame back panel is adsorbed by the negative pressure suction cup 21 on the photo frame back panel transverse moving device 4. Then, the photo frame back panel is placed on the photo frame back panel alignment device 5 for centering, so that the multi-axis robot can place the photo frame back panel into the hook stamping device 8 to ensure a uniform position of the photo frame back panel. Simultaneously, the hooks 51... The hooks 51 are arranged in the conveying channel 39 via the vibrating plate 34. The hook positioning and lateral movement assembly waits for the hooks 51 to enter at the output end of the conveying channel 39. Once the hook detection sensor 41 detects the output of the hooks 51 and it enters the designated position of the hook positioning and lateral movement assembly, the hook positioning and lateral movement assembly moves the hooks 51 laterally to the hook adsorption assembly 63. The hook adsorption assembly 63 adsorbs the hooks 51 that have been positioned at the correct angle, and then sends the hooks 51 into the hook stamping device 8, so that the hooks 51 are located on the back panel of the frame. This makes it convenient for the hook stamping device 8 to stamp and fix the hooks 51 on the back panel of the frame. The whole process can effectively position and convey the hooks 51, improve the assembly qualification rate of the hooks 51, and eliminate the need for manual operation, greatly improving the assembly production efficiency.

[0034] The lifting device 3 in this embodiment includes a first guide rail seat 9 installed on the inner wall of one side of the placement area 2. A first linear motor module 10 is installed on the first guide rail seat 9. The first linear motor module 10 is vertically arranged. A tray seat 11 is slidably installed on the first linear motor module 10. A tray 12 located in the placement area 2 is installed on the tray seat 11. Multiple photo frame back panels are placed on the upper end of the tray seat 11. The first linear motor module 10 drives the tray seat 11 to lift upward, so that the photo frame back panels rise until they are adsorbed by the negative pressure suction cup 21 on the photo frame back panel horizontal moving device 4, so as to facilitate transfer and centering. There is no need for manual loading of photo frame back panels, and the degree of automation is higher.

[0035] The frame back panel horizontal moving device 4 in this embodiment also includes a second guide rail seat 13. A second linear motor module 14 is installed on the second guide rail seat 13. The second linear motor module 14 is installed from the placement area 2 toward the frame back panel alignment device 5. A curved arm seat 15 is slidably installed on the second linear motor module 14. A curved arm 16 is installed on the curved arm seat 15. A suction cylinder 17 is installed at one end of the curved arm 16. A suction cup mounting plate 18 is installed on the cylinder shaft at the lower end of the suction cylinder 17. A plurality of negative pressure suction cups 19 are installed on the suction cup mounting plate 18. The plurality of negative pressure suction cups 19 are located directly above the placement area 2. After the frame back panel is raised, the negative pressure suction cups 19 are driven by the suction cylinder 17 to press against the frame back panel and adsorb it. Then, after retracting and resetting, they are moved by the second linear motor module 14 to move the adsorbed frame back panel to the frame back panel alignment device 5 and then lower the frame back panel.

[0036] Specifically, the frame back panel alignment device 5 includes a frame back panel support plate 21, a third linear motor module 26, and a fourth linear motor module 30. The top view projections of the third linear motor module 26 and the fourth linear motor module 30 are perpendicular. A first sliding plate 27 is slidably mounted on the third linear motor module 26, and a first alignment bracket 28 is mounted on the first sliding plate 27. At least one first alignment vertical plate 29 is provided on the first alignment bracket 28. A second sliding plate 31 is slidably mounted on the fourth linear motor module 30, and a second alignment bracket 32 ​​is mounted on the second sliding plate 31. At least one second alignment vertical plate 33 is provided on the second alignment bracket 32. The frame back panel support plate 21 is located between the third linear motor module 26 and the fourth linear motor module 30. The frame back panel support plate 21 is mounted on the frame 1 via a support rod 20. One side of plate 21 is provided with a first strip hole 25 corresponding to the first aligned vertical plate 29. One side of the frame back panel support plate 21 is provided with a second strip hole 24 corresponding to the second aligned vertical plate 33. The side opposite to the first strip hole 25 is provided with a first baffle 22 located on the frame back panel support plate 21. The side opposite to the second strip hole 24 is provided with a second baffle 23 located on the frame back panel support plate 21. After the frame back panel is placed on the frame back panel support plate 21, the first aligned vertical plate 29 moves into the first strip hole 25, and at the same time, the second aligned vertical plate 33 moves into the second strip hole 24, so that the frame back panel is attached to the first baffle 22 and the second baffle 23, so that the frame back panel is aligned on the frame back panel support plate 21, so as to ensure that the frame back panel is in the correct angle and position before being placed into the hook punching device 8.

[0037] It is worth noting that the output end of the conveying channel 39 in this embodiment is provided with a partition 45. The lower end of the partition 45 is connected to a partition cylinder 44. The partition cylinder 44 is fixedly installed at the lower end of the conveying channel 39 through the base 43. The partition 45 is located on the side of the hook detection sensor 41 away from the hook positioning transverse moving component. The partition 45 can be raised and lowered by the partition cylinder 44, so that the hook 51 vibrates through the vibrator 36, thereby arranging and moving in the conveying channel 39. Since the hook 51 forms a notch on the side close to the anti-slip teeth 38, before the hook 51 is output from the conveying channel 39, the partition 45 extends upward into the adjacent notch of the hook 51 to be output, separating the two adjacent hooks 5 and preventing two hooks 51 from being output at the same time.

[0038] The hook detection sensor 41 is installed on the side of the sensor mounting base 40. The hook detection sensor 41 is an infrared sensor. The sensor mounting base 40 is suspended above the output end of the conveying channel 39 by a support rod. The sensor mounting base 40 is also equipped with a hook top surface limiting piece 42. The hook top surface limiting piece 42 is provided with a detection hole, which is located directly below the hook detection sensor 41. This ensures that after the hook piece 51 is output to the hook positioning and lateral movement assembly, the hook detection sensor 41 needs to detect the hook piece 51 within the detection hole range to determine that it has reached the designated position. At the same time, the hook top surface limiting piece 42 can prevent the hook piece 51 from entering the hook positioning and lateral movement assembly and causing a large range of jumping, thereby improving the positional accuracy of the hook piece 51.

[0039] The hook positioning transverse component of this embodiment includes a support 46, a third guide rail seat 47 mounted on the upper end of the support 46, a first slide rail slider 48 mounted on the third guide rail seat 47, a transverse sliding plate 49 mounted on the first slide rail slider 48, a transverse cylinder 50 mounted on one end of the third guide rail seat 47, the cylinder shaft of the transverse cylinder 50 being connected to the transverse sliding plate 49, a gripper cylinder 52 mounted on the upper end of the transverse sliding plate 49, and grippers 53 on both sides of the upper end of the gripper cylinder 52 being equipped with a receiving device for the conveyor belt. The hook support 54 of the hook 51 output from the conveying channel 39 allows the hook support 54 to switch positions between the output end of the conveying channel 39 and the hook adsorption assembly 63. The position can be switched by the transverse cylinder 50 driving the gripper cylinder 52. The hook supports 54 on both sides form hook receiving grooves, so that after the hook 51 is output from the conveying channel 39, it can fall between the hook supports 54 on both sides and then be clamped by the gripper cylinder 52 to prevent position displacement during movement.

[0040] Specifically, a protrusion 55 is provided on the upper side of the middle end of the hook support 54 away from the two sides of the gripper 53. A third baffle 57 is provided on the side of the protrusion 55 away from the hook input direction. A limiting plate 56 is provided on the upper end of the protrusion 55 near the third baffle 57. One end of the limiting plate 56 extends into the upper part of the hook support 54. After being clamped by the protrusions 55 on both sides, the hook 51 is positioned between the protrusions 55 on both sides. At the same time, under the action of the limiting plate 56, the hook 51 is prevented from jumping during the clamping process, thus improving the positioning accuracy.

[0041] The hook feeding device 7 in this embodiment also includes a support base 58. A fourth guide rail base 59 is installed on the upper end of the support base 58. A second slide rail slider 60 is installed on the upper end of the fourth guide rail base 59. A slide rod 62 is slidably installed on the second slide rail slider 60. A hook adsorption assembly 63 is installed on one end of the slide rod 62. The other end of the slide rod 62 is connected to a slide rod cylinder 61. The cylinder body of the slide rod cylinder 61 is installed on the fourth guide rail base 59. After the hook 51 is clamped by the gripper cylinder 52 and the work position is switched, the slide rod 62 is driven by the slide rod cylinder 61, so that the hook adsorption assembly 63 moves between the protrusions 55 on both sides, thereby facilitating the adsorption of the hook 51.

[0042] Specifically, the hook-and-loop adsorption assembly 63 includes an adsorption base 64, with a pressure groove 65 at the upper end of the adsorption base 64. A magnet groove 66 is formed within the pressure groove 65, and a magnet 67 is installed within the magnet groove 66. A pressure block 68 is installed within the pressure groove 65. The lower end of the adsorption base 64 has an adsorption groove 69 that corresponds vertically to the magnet 67. A limiting protrusion 70 is provided on one side of the adsorption groove 69, and both ends of the adsorption groove 69 have limiting ramps 71 that match the shape of the hook-and-loop 51. The pressure block 68 can be installed in the pressure groove 65 with screws for easy replacement. Adjust magnet 67 so that the adsorption seat 64 moves between the two protrusions 55. The gripper cylinder 52 opens the gripper. Under the action of magnet 67, hook 51 is adsorbed into adsorption groove 69. At the same time, under the action of limiting inclined platform 71, the inclined pieces 78 on both sides of hook 51 are attached to the limiting inclined platform 71, so that hook 51 is aligned in adsorption groove 69. The stamping piece 79 on hook 51 protrudes from the two side surfaces of adsorption seat 64. After adsorbing hook 51, adsorption seat 64 moves hook 51 into hook stamping device 8 for subsequent stamping.

[0043] The hook-and-loop stamping device 8 includes a stamping base 72 composed of two side plates. A stamping cylinder 73 is mounted on the upper end of the stamping base 72. A cylinder shaft at the lower end of the stamping cylinder 73 is connected to a stamping head 74. The stamping head 74 is provided with a receiving groove 75 with an open lower end. The receiving groove 75 corresponds to the adsorption seat 64, allowing the adsorption seat 64 to extend into the receiving groove 75. Stamping protrusions 76 are provided on both sides of the receiving groove 75. A hook-and-loop fastener located below the stamping protrusions 76 is installed inside the stamping base 72. The worktable 77 and the receiving groove 75 allow the adsorption seat 64 to extend into the worktable, so that the stamping plate 79 on the hook 51 is directly below the stamping protrusion 76. The stamping protrusion 76 is driven to press down by the stamping cylinder 73, so that the stamping protrusion 76 presses against the stamping plate 79, thus fixing the stamping plate 79 to the back of the photo frame. Since the hook 51 is magnetically attracted in the adsorption groove 69, the hook 51 will automatically detach during the stamping process, so that the adsorption seat 64 can return to re-adsorb a new hook 51.

[0044] Throughout the entire process of this embodiment, the operator only needs to place the back panel of the photo frame in the placement area 2. Compared with the traditional assembly method, this greatly reduces the labor intensity of the operator, has a high degree of automation, and improves assembly efficiency.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
