[0002] In daily life, people record their lives by taking photos to leave commemorations and memories of a period of life. After the photos are developed, they are usually placed in photo frames. Photo frames need a back plate to fix the photos and have a certain moisture-proof function. During production, the back plate needs to be installed with accessories to fix it to the photo frame, and the triangular hook is one of them. At present, when installing the triangular hook into the back plate of the photo frame, the back plate of the photo frame is manually placed under the punching head of the machine, and then the triangular hook is placed in the reserved position of the back plate, and then the triangular hook is stamped and riveted to the back plate by rivets.

DETAILED DESCRIPTION

[0027] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, combined Figure 2 and Figure 3 The utility model discloses a feeding device for a photo frame backboard machine, comprising a platform 1, a material dropping mechanism 2, a slide block 3 and a rotary block 4.

[0029] The platform 1 is a work surface firmly placed on a horizontal ground, on which a positioning plate for placing the back plate of the photo frame, a rivet feeding mechanism for feeding rivets, and a punching mechanism for riveting the hook 10 to the back plate by rivet punching are installed. The platform 1 is provided with a first position 101, a second position 102, and a third position 103 at intervals. The first position 101 is a blanking position where the hook 10 is separated from the blanking mechanism 2, the second position 102 is a position where the slider 3 transfers the hook 10 and docks with the adsorption portion 41 of the rotary block 4, and the third position 103 is a position where the rotary block 4 transfers the hook 10 to the top of the positioning plate where the back plate of the photo frame is placed for riveting.

[0030] The material dropping mechanism 2 is disposed on the platform 1 and is located above the first position 101. The material dropping mechanism 2 is used to drop the hooks 10 onto the slide block 3 one at a time at the first position 101.

[0031] The slider 3 is disposed on the platform 1 and is located between the blanking mechanism 2 and the platform 1. The slider 3 moves horizontally between the first position 101 and the second position 102 relative to the platform 1 and is used to transfer the hook 10 from the first position 101 to the second position 102.

[0032] The rotary block 4 is arranged on the platform 1 and rotates axially in the horizontal plane. The rotary block 4 can be a rectangular block or a structure similar to a turntable; at least two adsorption parts 41 are arranged around the rotating shaft of the rotary block 4 on the end surface of the rotary block 4 facing the slider 3, and the adsorption parts 41 adsorb the hook 10. Since the hook 10 is usually made of metal material, the adsorption part 41 can be an electromagnetic sheet that generates magnetic attraction when powered; the adsorption part 41 rotates synchronously with the rotary block 4 and transfers the hook 10 from the second position 102 to the third position 103. Before the hook 10 is stamped and riveted to the back plate, it needs to be adsorbed on the adsorption part 41 all the time. The hook 10 will naturally detach from the adsorption part 41 when it is stamped, so the adsorption part 41 can also be a permanent magnet. In addition, the rotary block 4 is installed on a rotating base, and a rotating motor is installed in the rotating base to drive the rotary block 4 to rotate.

[0033] When the above technical solution is adopted, the hook 10 is first dropped from the dropping mechanism 2 at the first position 101 onto the slider 3, and then the slider 3 moves forward to the second position 102, so that one of the adsorption parts 41 of the rotary block 4 adsorbs the hook 10, and then the adsorption part 41 rotates to the third position 103 with the rotation of the rotary block 4. At this time, the hook 10 is located between the back plate and the rivet, and the punching head is at the top. The punching mechanism rivets the hook 10 to the back plate by punching.

[0034] exist Figure 4 In a preferred embodiment shown, in order to prevent the position deviation of the hook 10 when it falls on the slider 3, a first groove 301 is provided on the end of the slider 3 facing the second position 102 and away from the end surface of the platform 1; the slider 3 moves relative to the platform 1 and moves the first groove 301 to the first position 101, the blanking mechanism 2 aligns with the first groove 301 and makes the hook 10 fall into the first groove 301, and the hook 10 is limited by the first groove 301, so that the blanking position of each hook 10 is consistent. It should be noted that the hook 10 in the drawings of the present application is a triangular hook, and its structure includes a triangular hanging frame and a spring installed on one of the sides of the hanging frame, and a through hole for passing the rivet is provided on the spring, so the inner contour of the first groove 301 in this embodiment matches the outer shape of the triangular hook, but the feeding device of the present application is also applicable to hooks 10 of other shapes, and the corresponding first groove 301 can also be adjusted accordingly.

[0035] exist Figure 3 In a preferred embodiment shown, the slider 3 moves relative to the platform 1 and moves the first groove 301 to the second position 102, and one of the adsorption portions 41 of the rotary block 4 rotates synchronously with the rotary block 4 and passes over the first groove 301, and the adsorption portion 41 is arranged on the end surface edge of the rotary block 4 facing the platform 1 and aligned with the first groove 301.

[0036] exist Figure 6In a preferred embodiment shown, at least two second grooves 401 are provided on the end edge of the rotary block 4 facing the platform 1, and the adsorption portion 41 is arranged in the grooves. The adsorption portion 41 is aligned with the first groove 301 and adsorbs the hook 10, and one end of the hook 10 enters the second groove 401 and the other end of the hook 10 extends horizontally in a direction away from the adsorption portion 41. Since the hook 10 in the first groove 301 of the slider 3 needs to be adsorbed from above, the position of the rotary block 4 needs to be slightly higher than the slider 3, but the height difference between the two should not be greater than the thickness of one hook 10, so as to avoid the situation where the magnetic attraction of the adsorption portion 41 is insufficient to adsorb the hook 10.

[0037] exist Figure 2 In a preferred embodiment shown, the material dropping mechanism 2 includes a vibration plate 21 and a material guiding cylinder 22 .

[0038] The vibration plate 21 is disposed on the platform 1 and close to the first position 101. The vibration plate 21 is used to allow the hooks 10 to enter the guide barrel 22 in an orderly manner.

[0039] One end of the guide barrel 22 is connected to the vibration plate 21 and receives the hook 10 output by the vibration plate 21. The other end of the guide barrel 22 extends toward the platform 1 and is aligned with the first position 101. The guide barrel 22 guides the hook 10 to fall into the first groove 301. The slider 3 is arranged between the end of the guide barrel 22 facing the platform 1 and the platform 1. In the present application, the hook 10 includes a frame and a spring with a through hole, so a guide rod is inserted into the guide barrel 22, so that the frame of the hook 10 entering the guide barrel 22 is strung on the guide rod, and at the same time, a window groove that runs through from top to bottom is opened on the side wall of the guide barrel 22, so that the spring of the hook 10 extends out of the window groove.

[0040] exist Figure 3 In a preferred embodiment shown in the figure, in order to prevent multiple hooks 10 from falling onto the slider 3 at the same time, the interval between the top of the first groove 301 and the end of the guide barrel 22 facing the platform 1 is no greater than the thickness of the hook 10. Therefore, only one hook 10 falls into the first groove 301 at a time, and the other hook 10 on it is always in the guide barrel 22 during the process of the slider 3 moving forward to feed the material to the rear empty slot for reset.

[0041] exist Figure 4 In a preferred embodiment shown, the two adsorption parts 41 rotate synchronously with the rotary block 4 and rotate to the second position 102 and the third position 103 at the same time, so that the rotary block 4 can complete the feeding of a hook 10 every half a circle, which greatly improves the feeding efficiency.

[0042] exist Figure 4 In a preferred embodiment shown, the first position 101, the second position 102 and the third position 103 are arranged along a straight line to facilitate reasonable workstation arrangement and layout.

[0043] exist Figure 5 In a preferred embodiment shown, in order to realize the forward and backward movement of the slider 3, a guide rail 5 and a telescopic rod 6 are also included.

[0044] The guide rail 5 is disposed on the platform 1 and has two ends extending toward the first position 101 and the second position 102 respectively. The slider 3 is disposed on the guide rail 5 .

[0045] The telescopic rod 6 can be a hydraulic rod or a cylinder rod, and the telescopic rod 6 is arranged on the platform 1 and located at the end of the guide rail 5 away from the second position 102; the free end of the telescopic rod 6 is connected to the slider 3 and drives the slider 3 to move. The telescopic rod 6 is telescopic and movable, driving the slider 3 to move back and forth on the guide rail 5.

[0046] exist Figure 5 In a preferred embodiment shown, the telescopic rod 6 is connected to the end of the slider 3 away from the first groove 301, and the maximum stroke of the telescopic rod 6 is the same as the spacing between the first position 101 and the second position 102, which helps to accurately control the moving distance of the slider 3. When the telescopic rod 6 is retracted to the minimum stroke, the hook 10 in the blanking mechanism 2 can accurately fall into the first groove 301; and when the telescopic rod 6 is extended to the maximum stroke, the first groove 301 is located just below the adsorption portion 41.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
