Description

Technical Field

[0001] The invention relates to a photo frame processing device, in particular to a binding device for a photo frame backboard fixing piece. Background Art

[0002] The photo frame is mainly used for positioning the four sides of the photo, which is beneficial to protect the photo from damage and also has an aesthetic effect. The photo frame is usually hollow inside. When in use, the corresponding photo is placed in the blank space, and the position of the photo is fixed by locking the back plate of the photo frame; the specific locking method is that a fixing piece is nailed on the back plate of the photo frame, and the fixing piece includes a connecting nail and a spring (or a baffle), wherein the spring is provided with a mounting hole, and the lower part of the mounting hole has a lower convex part, the nail head of the connecting nail is connected to the mounting hole, and the connecting nail and the spring can rotate freely, and the connecting nail is embedded in the back plate of the photo frame; when in use, by rotating the spring (or baffle) on the back plate, the free end of the spring is clamped on the back of the photo frame to achieve the locking of the back plate, thereby achieving the purpose of fixing the photo. Among them, the rotation tightness of the spring will affect the user experience. If the connection between the spring and the back panel is too tight, it is not easy to adjust. If the connection between the spring and the back panel is too loose, it is easy to shift, resulting in poor fixing effect. Therefore, the tightness of the connection between the spring and the back panel of the photo frame is particularly important.

[0003] The rotation tightness of the spring piece is achieved by controlling the depth of the lower convex part of the mounting hole embedded in the photo frame back plate. The deeper the lower convex part of the mounting hole is embedded in the photo frame back plate, the tighter the connection effect. In addition, since multiple fixings are generally arranged on each photo frame back plate, it is necessary to ensure that the tightness of each fixing on the photo frame back plate is consistent when binding the fixings, so as to facilitate the use of the user. At the same time, this ensures that the spacing between each spring piece and the photo frame back plate is consistent, so that each clamping point of the photo frame back plate is clamped on the photo frame evenly.

[0004] When binding the photo frame back plate and the fixing parts, the driving stroke of the driving mechanism is generally pre-set directly to ensure the pressing depth of the punch head, thereby controlling the embedding depth of the spring piece mounting hole; however, during the processing, on the one hand, both the driving mechanism and the punch head have certain stroke errors, and the driving stroke of the driving mechanism is difficult to adjust to a fixed distance, which makes it difficult to ensure that the tightness of the fixing parts on the same photo frame back plate remains uniform; on the other hand, since the photo frame back plate is made of paper material, the sizes of the photo frame back plates of different batches are not the same, and due to the influence of moisture, the sizes of the photo frame back plates of the same batch will also change at different times, making it difficult to ensure that the tightness between the spring piece and the photo frame back plate after binding is appropriate and uniform using the existing stamping assembly method with set stroke. Summary of the invention

[0005] The present invention aims to overcome the deficiencies of the prior art and provide a binding device for photo frame back plate fixings, which can ensure that the tightness of each fixing on the photo frame back plate is consistent, thereby improving the binding quality.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A binding device for a photo frame back panel fixing part, characterized in that it includes a punching head and a vertical driving mechanism for driving the punching head to move vertically; a clamping positioning part is provided on the outer side of the punching head, the clamping positioning part extends to the outside of the fixing part in the transverse direction, and the bottom of the clamping positioning part is lower than the punching head; during punching, the bottom of the punching head acts on the fixing part, and when the punching head moves to the end position, the bottom of the clamping positioning part acts on the photo frame back panel; wherein, the distance between the bottom of the clamping positioning part and the bottom of the punching head plus the depth of the lower convex part of the mounting hole on the fixing part embedded in the photo frame back panel is equal to the distance between the bottom of the punching head and the lower convex part of the mounting hole on the fixing part when the punching head moves to the end position.

[0008] The working principle of the binding device of the above-mentioned photo frame back plate fixing member is:

[0009] Before punching and binding, a manipulator or other conveying mechanism and a positioning mechanism convey the photo frame back plate and the fixing part to the bottom of the punching head and position them. At this time, the punching part (corresponding to the mounting hole) on the fixing part is located directly below the punching head, and the clamping positioning part is located on the outside of the fixing part to prevent the clamping positioning part from colliding with the fixing part during punching; then, the vertical driving mechanism drives the punching head to move downward, and the bottom of the punching head first contacts the punching part of the fixing part, and gradually punches the connecting nails on the fixing part into the photo frame back plate; when the bottom of the clamping positioning part is pressed against the photo frame back plate, the punching head cannot continue to move downward and no longer presses down on the fixing part, that is, the punching head moves to the end position, completing the entire binding process. At this time, the distance between the bottom of the clamping positioning member and the bottom of the punching head plus the depth of the lower convex part of the mounting hole on the fixing member embedded in the photo frame back plate is equal to the distance between the bottom of the punching head and the lower convex part of the mounting hole on the fixing member, that is, the distance between the bottom of the punching head and the lower convex part of the mounting hole on the fixing member minus the distance between the bottom of the clamping positioning member and the bottom of the punching head is equal to the depth of the lower convex part embedded in the photo frame back plate; and because the distance between the bottom of the clamping positioning member and the bottom of the punching head is fixed, the depth of the lower convex part embedded in the photo frame back plate after the binding is finally completed also remains unchanged, so that the rotation tightness of the fixing base of the fixing member can be guaranteed each time the binding is performed, so as to realize unified mass production. In actual production, according to the needs of different batch models of photo frame back panels and related products, the depth of the lower convex part embedded in the photo frame back panel is different. At this time, it is only necessary to adjust the distance between the clamping positioning piece and the bottom of the punch head to change the binding effect, and adjust the position between the clamping positioning piece and the punch head. The operation is convenient and simple, which is conducive to ensuring the position accuracy between the two, thereby achieving the accuracy of the embedding depth of the lower convex part.

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 This is a schematic structural diagram of one specific implementation of the binding device of the photo frame back plate 11 fixing member of the present invention. DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with examples and drawings, but the embodiments of the present invention are not limited thereto.

[0024] See also Figure 1 The binding device of the photo frame backboard fixing member of this embodiment comprises a punching head 9 arranged corresponding to the punching position of the fixing member and a vertical driving mechanism 1 driving the punching head 9 to move vertically; a pressing and positioning member 7 is arranged on the outer side of the punching head 9, and the pressing and positioning member 7 extends to the outside of the fixing member in the transverse direction, and the bottom of the pressing and positioning member 7 is lower than the punching head 9. During punching, the bottom of the punching head 9 acts on the fixing member, and when the punching head 9 moves to the end position, the bottom of the pressing and positioning member 7 acts on the photo frame backboard 11. The distance A between the bottom of the clamping positioning member 7 and the bottom of the punch head 9 plus the depth of the lower convex part 14 of the mounting hole 12 on the fixing member embedded in the photo frame back plate 11 is equal to the distance B between the bottom of the punch head 9 and the lower convex part 14 of the mounting hole 12 on the fixing member when the punch head 9 moves to the terminal position (in actual production, the distance A can be set to be slightly less than the height B, and the part of B that is more than A is the depth of the lower convex part 14 of the mounting hole 12 embedded in the photo frame back plate 11). Referring to the fixing member of the prior art, the fixing member of this embodiment includes a fixing base 10 and a connecting nail 15, wherein the fixing base 10 can be composed of a spring sheet, a hook or other parts; wherein the fixing base 10 is provided with a mounting hole 12, and the connecting nail 15 is assembled on the mounting hole 12. Specifically, the connecting nail 15 is fixed on the photo frame back plate 11, and the fixed base 10 is rotatably connected to the connecting nail 15. During binding, the lower part of the connecting nail 15 is completely inserted into the photo frame back plate 11, and the lower convex part 14 of the mounting hole 12 of the fixed base 10 is slightly embedded in the photo frame back plate 11. The embedding depth of the lower convex part 14 affects the rotation tightness of the fixed base 10.

[0025] See also Figure 1 The vertical driving mechanism 1 includes a driving assembly and a power source, and the driving assembly includes a driving member 2 and an elastic element; wherein one end of the driving member 2 is connected to the power source, and the other end is connected to the top of the punch head 9 through a connecting member 6; the elastic element is arranged between the driving member 2 and the punch head 9. By setting such a vertical driving mechanism 1, the vertical driving of the punch head 9 is realized, and at the same time, by setting the elastic element, the driving of the punch head 9 is an elastic driving, that is, the driving force is transmitted from the driving member 2 to the punch head 9 through the elastic element, avoiding rigid driving of the punch head 9, which is beneficial to protecting the binding device, reducing impact vibration, and improving the binding quality.

[0026] See also Figure 1The connecting member 6 is arranged on the punching head 9 , and a buffer connecting hole 5 is provided on the driving member 2 . The buffer connecting hole 5 is larger than the connecting member 6 , and the connecting member 6 is inserted into the buffer connecting hole 5 . Under normal conditions, under the elastic force of the elastic element, the connecting member 6 contacts the bottom of the buffer connecting hole 5 to resist the elastic force of the elastic element; during operation, driven by the power source, the driving member 2 moves downward, and at the same time, under the elastic force of the elastic element, the punch head 9 is driven downward to perform the binding operation. When the punch head 9 contacts the fixing member, the distance between the punch head 9 and the driving member 2 will be reduced, thereby compressing the elastic element. At this time, since the buffer connecting hole 5 is larger than the connecting member 6, a certain buffer gap is left in the buffer connecting hole 5, thereby providing a buffering space for the relative movement between the driving member 2 and the punch head 9; and since the connecting member 6 is inserted into the buffer connecting hole 5, when the driving member 2 completes the stapling operation and moves upward, the connecting member 6 will be suspended and driven, thereby driving the punch head 9 to move upward. In this embodiment, the connecting member 6 is a pin; the connecting member 6 can also be composed of other special-shaped rods, and the buffer connecting hole 5 is set as a special-shaped hole matching the special-shaped rod, which can effectively limit the position of the driving member 2 and avoid rotation.

[0027] See also Figure 1 The top of the punch head 9 is provided with a mounting groove 16, the bottom of the driving member 2 is provided with a connector 4 extending downward, and the two ends of the connector 6 are respectively connected to the two opposite inner walls of the mounting groove 16. In this way, the connection part of the punch head 9 and the driving member 2 can be embedded in the mounting groove 16, making the connection between the two closer, thereby making the entire structure more compact.

[0028] See also Figure 1 The elastic element is composed of a spring 3, which is sleeved on the driving member 2 and the punch head 9; one end of the spring 3 is pressed against the bottom of the power output member of the power source, and the other end is pressed against the top of the pressing positioning member 7. In this way, the elastic force of the spring 3 can be evenly applied to the punch head 9, so that the punching force on the fixing member during binding is more evenly dispersed, which is conducive to improving the binding quality.

[0029] See also Figure 1 , the power source is a device capable of outputting vertical reciprocating motion, such as a punching machine. Specifically, the power source may be a cylinder, the cylinder body of which is fixedly connected to the frame, and the telescopic member of the cylinder is connected to the top of the driving member 2. Using a cylinder as a power source is conducive to improving the buffering effect, especially compared with power sources such as motors and screw transmission mechanisms, the cylinder has a certain self-adjustment ability during driving, thereby making the driving effect better.

[0030] See also Figure 1, the bottom of the punch head 9 is arranged correspondingly to the snap ring 13 on the top surface of the connecting nail 15 of the fixing piece. Since the main process in the binding process is to insert the connecting nail 15 on the fixing piece into the photo frame back plate 11, the bottom of the punch head 9 is arranged correspondingly to the snap ring 13 on the top surface of the connecting nail 15, so that the force of the punch head 9 on the connecting nail 15 is more concentrated during the binding process, which is conducive to the connecting nail 15 being inserted into the photo frame back plate 11 smoothly and effectively; in the final binding process, the snap ring 13 on the connecting nail 15 drives the entire fixing piece to move further downward a short distance (i.e., the process of the lower convex part 14 being embedded in the photo frame back plate 11), thereby completing the entire binding process.

[0031] See also Figure 1 The pressing and positioning member 7 is cylindrical and sleeved on the outer wall of the punching head 9. The corresponding position of the pressing and positioning member 7 and the fixing member is provided with an escape groove 8 for evading the fixing member. By providing the cylindrical pressing and positioning member 7, it can be pressed on the photo frame back plate 11 around the punching part of the fixing member during binding, thereby more effectively limiting the punching head 9 from moving downward, which is conducive to improving the positioning accuracy of the punching head 9, thereby improving the binding accuracy of the fixing member.

[0032] See also Figure 1 The clamping positioning member 7 includes a plurality of positioning blocks, which are arranged at equal intervals along the outer wall of the punching head 9. By setting a plurality of positioning blocks, the plurality of positions outside the punching part of the fixing member can be clamped during binding, effectively limiting the punching head 9 from moving downward further, and improving the positioning accuracy.

[0033] See also Figure 1 The working principle of the binding device of the photo frame back plate fixing member of this embodiment is:

[0034] Before punching and binding, the photo frame back plate 11 and the fixing part are conveyed to the bottom of the punching head 9 and positioned by a manipulator or other conveying mechanism and positioning mechanism. At this time, the punching part on the fixing part (the corresponding part of the mounting hole 12) is located directly below the punching head 9, and the clamping positioning part 7 is located on the outside of the fixing part to prevent the clamping positioning part 7 from colliding with the fixing part during punching; then, the vertical driving mechanism 1 drives the punching head 9 to move downward, and the bottom of the punching head 9 first contacts the punching part of the fixing part, and gradually punches the connecting nails 15 on the fixing part into the photo frame back plate 11; when the bottom of the clamping positioning part 7 is pressed on the photo frame back plate 11, the punching head 9 cannot continue to move downward and no longer presses down on the fixing part, that is, the punching head 9 moves to the end position to complete the entire binding process. At this time, since the distance A between the bottom of the clamping positioning member 7 and the bottom of the punching head 9 plus the depth of the lower convex portion 14 of the mounting hole 12 on the fixing member embedded in the photo frame back plate 11 is equal to the distance B between the bottom of the punching head 9 and the lower convex portion 14 of the mounting hole 12 on the fixing member, that is, the distance B between the bottom of the punching head and the lower convex portion 14 of the mounting hole 12 on the fixing member minus the distance A between the bottom of the clamping positioning member 7 and the bottom of the punching head 9 is equal to the depth of the lower convex portion 14 embedded in the photo frame back plate 11; and since the distance A between the bottom of the clamping positioning member 7 and the bottom of the punching head 9 is fixed, the depth of the lower convex portion 14 embedded in the photo frame back plate 11 after the binding is finally completed also remains unchanged, so that the rotation tightness of the fixing base 10 of the fixing member can be guaranteed each time the binding is performed, so as to realize unified mass production. In actual production, the depth of the lower convex part 14 embedded in the photo frame back plate 11 is different for different batches of photo frame back plates 11 and related product needs. At this time, it is only necessary to adjust the distance between the pressing positioning member 7 and the bottom of the punch head 9 to change the binding effect, and the position between the pressing positioning member 7 and the punch head 9 is adjusted. The operation is convenient and simple, which is conducive to ensuring the position accuracy between the two, thereby achieving the precision of the embedding depth of the lower convex part 14. Specifically, the embedding depth of the lower convex part 14 is used to adjust the tightness, and its size does not need to be too large. As an example, in actual production, the embedding depth of the lower convex part 14 can be controlled between 0.01mm-0.02mm.

[0035] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
