[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 with 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.

[0003] Chinese patent CN216966055U discloses a material feeding and receiving device for a photo frame backboard machine, which transfers the rivets in the vibrating plate to the bottom of the punch head through a material guide mechanism with a bent front end, and the rear end of the material guide mechanism is hinged on a fixed seat. When the punch head punches the rivet, the front end of the material guide mechanism needs to rotate sideways to avoid the punch head.

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 3 The utility model discloses a photo frame back plate hanging buckle pressing device, which comprises a platform 1, a support seat 2, a punch head 3, a material guide mechanism 4, a cam 5 and a stop pin 6.

[0029] The platform 1 is a work surface firmly placed on a horizontal ground, on which a positioning plate for placing a photo frame back plate is installed.

[0030] The support base 2 is arranged on the platform 1. The support base 2 is provided with a control element and a driving mechanism for controlling the punch head 3 to move up and down.

[0031] The punch head 3 is arranged on the support seat 2 and is located above the positioning plate. The punch head 3 moves downward to perform a punching action and moves upward to reset.

[0032] The function of the material guide mechanism 4 is to feed the rivets. One end of the material guide mechanism 4 is hinged to a fixed position above the platform 1 and the other end is bent and extended to the bottom of the punch head 3. The material guide mechanism 4 is similar to a hollow flat cylinder, and its bottom surface is provided with through grooves along the extension direction of its two ends. The rivet cap is located in the material guide mechanism 4, and the rivet body falls by its own weight and is located in the through groove, so that the rivets can slide along the material guide mechanism 4 to their free ends one at a time. The free end of the material guide mechanism 4 rotates around its hinged connection part and moves away from or close to the punch head 3. Its function is that when the punch head 3 punches the rivet, the free end of the material guide mechanism 4 rotates to make way.

[0033] The cam 5 is arranged on the support seat 2 and rotates axially in a horizontal direction. The rotation axis of the cam 5 is located at the center of its base circle, the outer peripheral wall of the protruding part of the cam 5 is in contact with the outer wall of the material guide mechanism 4, and a notch 501 is provided on the edge of the cam 5, and the two ends of the notch 501 extend around the rotation axis of the cam 5 in an arc shape.

[0034] The stop pin 6 is arranged on the punch head 3 and moves synchronously with the punch head 3 .

[0035] When the above technical solution is adopted, the stop pin 6 moves downward with the punch head 3 and abuts against the inner wall of the groove 501 at one end close to the platform 1. The stop pin 6 pushes the cam 5 to rotate and causes the cam 5 to push the free end of the material guide mechanism 4 away; the stop pin 6 moves upward with the punch head 3 and abuts against the inner wall of the groove 501 at one end away from the platform 1. The stop pin 6 pushes the cam 5 to rotate in the opposite direction, and the free end of the material guide mechanism 4 rotates toward the direction close to the punch head 3. In this process, due to the presence of the notch 501 on the cam 5, when the punch head 3 moves downward for punching, the punch head 3 first moves downward to a certain height and makes its end contact with the rivet, and the stop pin 6 will contact the lower end of the notch 501. At this time, the stop pin 6 pushes the cam 5 to rotate and drives the free end of the guide mechanism 4 to rotate to make way; when the punch head 3 moves upward to reset, the punch head 3 first moves upward to a certain height, and the stop pin 6 will contact the upper end of the notch 501 to make the cam 5 rotate. As the punch head 3 gradually moves upward into place, the free end of the guide mechanism 4 rotates into place, thereby avoiding the problem that the free end of the guide mechanism 4 and the punch head 3 start to reset at the same time, and the two will directly collide during the movement.

[0036] exist Figure 4 and Figure 5 In a preferred embodiment shown, specifically, the range of up and down movement of the punch head 3 has an initial position and an end position, the punch head 3 is in the initial position, the stop pin 6 abuts against the inner wall of the end of the notch 501 away from the platform 1, the punch head 3 moves down to the end position, the stop pin 6 abuts against the inner wall of the end of the notch 501 close to the platform 1 and pushes the cam 5 to rotate a preset angle, the punch head 3 moves back to the initial position, the stop pin 6 abuts against the inner wall of the end of the notch 501 away from the platform 1 and pushes the cam 5 to rotate in the opposite direction by a preset angle, by setting this preset angle, the purpose of pushing the cam 5 to rotate by the stop pin 6 and controlling the rotation angle of the free end of the material guide mechanism 4 can be achieved.

[0037] exist Figure 4 In a preferred embodiment shown, a sliding pin 7 is also included.

[0039] One end of the sliding pin 7 is fixed on the support base 2 and the other end thereof extends horizontally and passes through the window slot 502 .

[0040] The sliding pin 7 is arranged to pass through the window groove 502, and has two functions: one is to prevent the cam 5 from rotating a full circle and make the protruding part of the cam 5 break away from the contact with the outer wall of the material guide mechanism 4; the other is to limit the rotation range of the cam 5, so as to accurately control the rotation angle of the free end of the material guide mechanism 4.

[0041] exist Figure 6In a preferred embodiment shown, a limiting member 8 is also included.

[0042] A return spring is arranged in the hinged part of the material guiding mechanism 4 to make the free end of the material guiding mechanism 4 rotate toward the direction approaching the punch head 3 and return to its original position.

[0043] The limiter 8 is arranged on the support seat 2, and abuts against the outer wall of the guide mechanism 4 after reset, and separates the free end of the guide mechanism 4 from the end of the punch head 3, so that a certain distance is always maintained between the two, thereby avoiding direct collision between the two.
