Description

Technical Field

[0001] This utility model relates to the field of automated installation technology of picture frame support legs, and in particular to an automated installation machine for picture frame support legs. Background Technology

[0002] Picture frame supports are an important accessory for tabletop picture frames, used to support the frame and keep it in a stable tilted position when placed. Automatic installation machinery is an automated device designed for the installation of picture frame supports, integrating functional modules such as material storage, feeding, gripping, positioning, and riveting.

[0003] The equipment used in installing picture frame legs mainly falls into two categories: manual assistance and semi-automatic machinery. One type involves stand-alone frames with legs attached to the back panel using metal fittings and rivets. These fittings are typically installed manually or with simple machines. The process involves first installing the back panel at the bottom, then placing the metal fittings in the middle, and finally placing the legs on top and hammering them in place. The other type uses machinery. This also requires first placing the back panel under the machine's pressing device, then the machine delivers the back clips, and finally, the person manually places the legs on top of the back clips before starting the machine.

[0004] Existing automatic frame support installation devices have significant shortcomings. The process requires repeating the above steps for each frame, and the manual positioning accuracy is unstable. If the frame is not positioned correctly or the operation is improper, the product may be damaged. During manual operation, the hands need to be close to the stamping area, and there is a lack of effective isolation and protection, which can easily lead to hand injuries. In addition, the efficiency is also low. Therefore, an automatic frame support installation machine is proposed to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic frame support foot installation machine, including a frame 1, with multiple core functional mechanisms fixedly connected to the top. The top of the frame 1 is fixedly connected to a back plate hardware vibratory feeder direct vibration feeding mechanism 2, a back buckle pushing mechanism 3, a back plate storage bin 4, a support foot storage bin 5, a support foot robotic gripping mechanism 6, a back plate servo pushing mechanism 7, a riveting mechanism 8, and a support foot pushing assembly 9. The mechanisms work together to achieve a fully automated installation process for the frame support feet.

[0036] The riveting mechanism 8 includes a riveting motor 81, which is externally and fixedly connected inside the riveting mechanism 8. An off-axis reducer 84 is fixedly connected to the drive end of the riveting motor 81. The reducer converts the high-speed rotational motion of the motor into low-speed, high-torque power suitable for riveting. A downward pressing link 82 is fixedly connected to the drive end of the off-axis reducer 84. The link converts the rotational motion of the reducer into linear downward pressing motion. A riveting module 83 is fixedly connected to the bottom of the downward pressing link 82. When the link presses down, riveting occurs. Module 83 acts directly on the joint between the back buckle, the support leg, and the back plate, and completes the riveting and fixing through stamping. The support leg pushing component 9 includes a second pushing cylinder 92. The top of the second pushing cylinder 92 is on the top of the frame 1. The drive end of the second pushing cylinder 92 is fixedly connected to the support leg pushing module 91. When the robot places the support leg on the pushing module, the second pushing cylinder 92 is activated to push the support leg pushing module 91 to move along a preset trajectory, and finally send the support leg to the riveting station above the back buckle to prepare for the subsequent riveting action.

[0037] Reference Figure 2 and Figure 3 The backplate hardware vibratory feeder direct vibration feeding mechanism 2 includes a backplate hardware vibratory feeder vibrator 21, which is externally fixedly connected to the top of the frame 1. A hardware product vibratory feeder 22 is externally fixedly connected to the backplate hardware vibratory feeder vibrator 21. The mechanism mainly includes the backplate hardware vibratory feeder vibrator 21 and the hardware product vibratory feeder 22. The back buckle pushing mechanism 3 includes a pushing cylinder 31, which is externally fixedly connected to the top of the frame 1. The pushing cylinder 31 is the driving core. The drive end of the air delivery cylinder 31 is fixedly connected to the push module 32. The bottom of the push module 32 is slidably connected to the slide rail 34 to ensure stable guidance during the pushing process. The push module 32 is fixedly connected to the front module suction head 33, which is a gripping component. A strong magnet is built into the front of the front module suction head 33. When the back buckle is transported from the straight vibration track to the gripping position, the bottom of the push module 32 is slidably connected to the slide rail 34. After the magnet attracts the back buckle, the push module 32 continues to push along the slide rail to accurately place the back buckle in the preset position of the back plate.

[0038] The back panel storage bin 4 includes a module base plate 41. The bottom of the module base plate 41 is fixedly connected to the top of the back panel servo pushing mechanism 7. The back panel storage bin 4 is used to store the back panels of the picture frame to be processed and to realize size adaptation and adjustment. A back panel limiting module 42 is fixedly connected to the outside of the module base plate 41. A movable slider 45 is fixedly connected to the bottom of the module base plate 41. A screw 46 is fixedly connected to the bottom of the movable slider 45, so that the movable slider 45 can be adjusted in position by rotating the screw 46. An adjusting rocker arm 43 is fixedly connected to the right side of the screw 46. Shaking the adjusting rocker arm 43 drives the screw 46 to rotate. The movable slider 45 slides along the base plate as the screw 46 rotates. Module baffles 44 are fixedly connected to the top left and right sides of the module base plate 41, which drive the module baffles 44 to open or close synchronously, so that the back panel is in a stable state waiting to be pushed in the storage bin.

[0039] Reference Figures 4 to 6 The support-leg storage bin 5 includes a second modular base plate 51, the bottom of which is fixedly connected to the top of the frame 1. Support-leg limiting guide posts 52 are fixedly connected to the top of the second modular base plate 51. The second modular base plate 51 serves as the load-bearing foundation. Support-leg limiting guide posts 52, made of strip-shaped steel columns, are provided in three directions at the top, forming a closed-loop limiting mechanism for the support legs. An adjusting rocker arm 53 is fixedly connected to the front of each support-leg limiting guide post 52. Shaking the adjusting rocker arm 53 changes the spacing between the guide posts, thus adapting to different specifications of support legs and ensuring that the support legs are neatly stacked within the storage bin for easy gripping by the robotic arm. The support-leg robotic arm gripping mechanism 6 includes upper and lower... The vertical moving cylinder 62 is externally fixed to the top of the frame 1 and fixed to the horizontal moving component. The drive end is directly connected to the robotic suction cup 63 to control the lifting and lowering of the suction cup. The drive end of the vertical moving cylinder 62 is fixedly connected to the robotic suction cup 63. The top of the frame 1 has a horizontal moving cylinder 61. The horizontal moving cylinder 61 is installed on the top of the frame 1 and its drive end is connected to the horizontal moving component of the robotic suction cup 63 to realize the horizontal movement of the suction cup between the storage bin and the pushing component. One end of the robotic suction cup 63 is outside the horizontal moving cylinder 61.

[0040] The other end of the robotic suction cup 63 is fixedly connected to the bottom of the up-and-down moving cylinder 62. The suction cup is moved above the support leg storage bin 5 by the left-and-right moving cylinder 61. It is then moved by both the left-and-right moving cylinder 61 and the up-and-down moving cylinder 62, ultimately placing the support leg on the pushing module. The backplate servo pushing mechanism 7 includes a servo motor 71, which is externally fixedly connected to the top of the frame 1. The servo motor 71 is a precision drive component. A second screw 74 is fixedly connected to the drive end of the servo motor 71. A pushing stop 73 is fixedly connected to the outside of the second screw 74. A second slide rail 72 is slidably connected to the bottom of the pushing stop 73. To ensure stable pushing trajectory, the external fixed connection of the off-axis reducer 84 is to the front of the riveting motor 81, and the external fixed connection of the off-axis reducer 84 is to the rear of the pressing link 82. The pushing stop 73 is a specially made template with two fin-shaped protrusions. When pushing the bottom back plate, the fin-shaped vertical surface fits against the back plate and pushes it along the slide rail to the bottom of the riveting mechanism. After being pushed into place, the servo motor 71 reverses and drives the stop to retract. At this time, the rear arc surface of the stop faces upward to avoid scraping other back plates in the storage bin when retracting. After completing one riveting, the mechanism pushes the next back plate again, and at the same time pushes the processed back plate into the finished product basket to achieve continuous operation.

[0041] Working principle: When the machine is started, the vibrator 21 of the back plate metal vibratory feeder in the back plate metal vibratory feeder 2 performs a vibratory pushing motion. The servo motor 71 in the back plate servo pushing mechanism 7 at the bottom of the back plate storage bin 4 is started, causing the screw 74 to rotate, which drives the pushing block 73 to slide against the bottom slide rail 72, pushing the back plate to the bottom of the riveting mechanism 8. The pushing cylinder 31 is started, pushing the front module suction head 33 to move along the slide rail 34 to the bottom of the riveting mechanism 8. The left and right moving cylinder 61 and the up and down moving cylinder 61 are then activated. When cylinder 62 is activated, the robotic arm suction cup 63 picks up the support foot and moves it to the bottom of the support foot pushing assembly 9. The support foot is placed on top of the support foot pushing module 91. The support foot is pushed to the position of the back buckle pushing mechanism 3 by activating the second pushing cylinder 92. The riveting motor 81 is activated, and the connecting off-axis reducer 84 drives the pressing rod 82 to move, so that the riveting module 83 fixes the back buckle and support foot at the bottom. After the fixation is completed, the back plate servo pushing mechanism 7 pushes the back plate to send the next back plate to the bottom position of the riveting mechanism 8.

[0042] Place the back plate into the back plate storage bin 4. By adjusting the rotation of rocker arm 1 43, the screw 1 46 rotates, driving the movable slider 45 and module baffle 44 to move. Under the back plate limiting module 42, adjust the back plate to a suitable position in the back plate storage bin 4. Place the support foot into the support foot storage bin 5. Adjust the support foot limiting guide post 52 to a suitable support foot size by adjusting rocker arm 2 53. Subsequently, it is necessary to replace the riveting motor 81 and only need to replace the corresponding hardware product vibratory plate 22 and riveting module 83 to complete the adaptation. This realizes the replacement of repetitive picking and positioning actions in traditional manual and semi-automatic operations, avoiding product damage and work injury risks caused by improper operation, and improving production stability and safety.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
