Description

Technical Field

[0001] The utility model relates to the technical field of photo frame corner nailing machines, and specifically relates to a photo frame corner nailing machine. Background Art

[0002] In the assembly of various angle joints such as photo frames, picture frames, mirror frames, cabinets, and wooden door buckles, an angle nailing machine is usually required to nail V-shaped angle nails into the joints to fix the two adjacent frame strips.

[0003] In practice, corner nailing machines typically use a pair of presser feet, which press downward from above, to press the exposed surface of the frame strips. However, picture frames come in a wide variety of sizes and shapes, and even the outer surfaces of the frame strips may have curved transition areas. Especially for wide frame strips, a single pair of presser feet cannot guarantee 100% compression. If the frame strips are not securely pressed, the corner nails may shift or warp at the edges when driving into the joints, resulting in improper installation of the corner nails. Furthermore, if the presser feet apply too much force, indentations may appear on the exposed surface of the frame strips, affecting the product's appearance. Therefore, improvements and optimizations to existing technologies are needed. Utility Model Content

[0039] In the utility model, specifically including a workbench, a main presser foot, an auxiliary presser foot, a cross frame, a slide seat one and a slide seat two; the main presser foot includes a slide rod, a foot seat, a pressure frame seat and a spring; wherein the number of the foot seat, the pressure frame seat and the springs are all several. In this embodiment, the number of the foot seat and the pressure frame seat is preferably two respectively, the number of the springs is preferably four, and each foot seat and pressure frame seat corresponds to two springs; when working, it is determined whether to use the auxiliary presser foot according to the size and model of the frame strip; the operation process is described by taking the simultaneous selection of the main presser foot and the auxiliary presser foot as an example.

[0040] Before use, adjust the slide bar up and down to position the frame press seat appropriately according to the shape and thickness of the frame strip. Simultaneously, slide the auxiliary presser foot up and down to the appropriate height. Adjust the spacing between slides 1 and 2 to accommodate the desired frame strip. Two springs, one above and one below, are located between the foot and the frame press seat. The lower spring is compressed, while the upper spring is extended or in its natural state.

[0041] During use, the cut frame strips are placed on the workbench and the joints of the frame strips are aligned; then slide one is driven to slide until slide one is located above the outer corner of the joints of the two frame strips; slide two is driven to slide until slide two is located above the inner corner of the joints of the two frame strips; then with the help of the built-in linear drive one on the workbench, the linear drive one is preferably a cylinder; the workbench is built with a pressure-stabilizing air bag (or air tank) in the prior art to provide a pressure-stable air source for the linear drive one; the pressure-stabilizing air bag is connected to the linear drive one through a connecting air pipe (not shown in the accompanying drawings) and provides a stable air source.

[0042] Once the linear actuator is activated, the cross frame, slides 1 and 2, and the main and auxiliary presser feet simultaneously slide downward until the frame and auxiliary presser feet come into contact with the frame strip. The frame strip is then compressed and secured with the main and auxiliary presser feet. After the frame and the exposed surface of the frame strip are in contact, the frame holder slides toward the cross frame on the footrest. The spring below gradually releases its accumulated force, while the spring above gradually shortens and accumulates its force until the frame holder can no longer slide on the footrest. The sliding of the frame holder and the expansion and contraction of the springs cushion the impact between the frame holder and the frame strip, preventing it from leaving marks on the exposed surface of the frame strip while maintaining the required compression force on the frame strip. The two footrests are typically angled 90 degrees apart. For unusually angled frames, the main and auxiliary presser feet can be adjusted to different angles. This ensures stable compression of the frame strip, preventing uneven force on the frame strip, which can lead to poor nailing results or failure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0051] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0052] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0053] Example 1, refer to Figures 1 to 3 , which is the first embodiment of the utility model, provides a photo frame corner nailing machine.

[0054] In this embodiment, it specifically includes a workbench 1, a main presser foot 2, an auxiliary presser foot 3, a cross frame 4, a slide 1 5 and a slide 2 6; the main presser foot 2 includes a slide rod 7, a foot seat 8, a pressure frame seat 9 and a spring 10; wherein the number of the foot seat 8, the pressure frame seat 9 and the spring 10 are all several. In this embodiment, the number of the foot seat 8 and the pressure frame seat 9 is preferably two respectively, and the number of the spring 10 is preferably four, and each foot seat 8 and the pressure frame seat 9 corresponds to two springs 10; when working, whether to use the auxiliary presser foot 3 is determined according to the size and model of the frame strip; the operation process is explained by taking the simultaneous selection of the main presser foot 2 and the auxiliary presser foot 3 as an example.

[0055] Before use, adjust the slide bar 7 up and down to the desired position of the frame press seat 9, depending on the shape and thickness of the frame strip. Simultaneously, adjust the auxiliary presser foot 3 up and down to the desired height. Adjust the spacing between slides 1 and 2 to accommodate the desired frame strip. Two springs 10 are located between foot 8 and the frame press seat 9, one above and one below. The lower spring 10 is compressed, while the upper spring 10 is extended or in its natural state.

[0056] During use, the cut frame strips are placed on the workbench 1 and the joints of the frame strips are aligned; then the slide 1 5 is driven to slide until the slide 1 5 is located above the outer corner of the joints of the two frame strips; the slide 2 6 is driven to slide until the slide 2 6 is located above the inner corner of the joints of the two frame strips; then with the help of the linear drive 1 built into the workbench 1, the linear drive 1 is preferably a cylinder; the workbench 1 is equipped with a pressure-stabilizing air bag (or an air tank) in the prior art to provide a pressure-stable air source for the linear drive 1; the pressure-stabilizing air bag is connected to the linear drive 1 through a connecting air pipe (not shown in the drawing) and provides a stable air source.

[0057] After the linear actuator is activated, the horizontal frame 4, slide 1 5, slide 2 6, main presser foot 2, and auxiliary presser foot 3 simultaneously slide downward until the frame and auxiliary presser foot 3 come into contact with the frame strip. The frame strip is then compressed and secured with the help of the main presser foot 2 and auxiliary presser foot 3. After the frame and the exposed surface of the frame strip are in contact, the frame seat 9 slides on the footrest 8 toward the horizontal frame 4. At this time, the lower spring 10 gradually releases the elastic force accumulated by compression, while the upper spring 10 gradually shortens and accumulates elastic force until the frame seat 9 can no longer slide on the footrest 8. The sliding of the frame seat 9 and the expansion and contraction of the spring 10 cushion the impact force between the frame seat 9 and the frame strip, preventing the frame seat 9 from leaving an indentation on the exposed surface of the frame strip while ensuring the compression force on the frame strip. The two footrests 8 generally form a 90-degree angle. When encountering a photo frame with a special angle, the main presser foot 2 and auxiliary presser foot 3 can be replaced at different angles. This will achieve stable compression of the frame strips and avoid uneven force on the frame strips, resulting in poor nailing effect or failure.

[0058] Example 2, refer to Figure 1~Figure 2 This is the second embodiment of the present invention. Based on the angle nailing machine comprising a workbench 1, a main presser foot 2, and an auxiliary presser foot 3, this embodiment further adds a main rubber pad 11 and an auxiliary rubber pad 12. During use, the main rubber pad 11 and the auxiliary rubber pad 12 prevent the main presser foot 2 and the auxiliary presser foot 3 from directly pressing against the exposed surface of the frame strip, thereby preventing indentations on the exposed surface of the frame strip. This improves the surface quality of the frame strip after nailing.

[0059] Example 3, refer to Figures 1 to 4This is the third embodiment of the present invention. Based on the corner nailing machine comprising a workbench 1, a main presser foot 2, and an auxiliary presser foot 3, this embodiment further comprises a nail storage unit 13, a nailing unit 14, a conveyor belt 15, and a nail-pushing unit 16. During operation, the workbench 1 includes a built-in rotary actuator 1, a linear actuator 2, and a linear actuator 3. Rotary actuator 1 is preferably an electrically driven motor, while linear actuators 2 and 3 are preferably pneumatic cylinders. Linear actuator 2 provides power to nailing unit 14, while linear actuator 3 provides power to nail-pushing unit 16. The workbench 1 also includes a built-in pressure-stabilizing airbag (or air tank) to provide a stable air source for linear actuators 2 and 3. It also includes a built-in high-speed exhaust valve to ensure air pressure for rapid nailing. The pressure-stabilizing airbag is connected to the high-speed exhaust valve, linear actuators 2 and 3 via a connecting air pipe (not shown in the drawings) to provide a stable air source.

[0060] The conveyor belt 15 is driven by the power output by the rotary driver 1, which in turn drives the nail storage member 13, the nail driving member 14 and the nail pushing member 16 to move synchronously, so that the corner nails are aligned with different positions of the overlapping parts of the frame strips. The nailing operation is carried out with the help of the power output by the linear driver 2, and a row of corner nails are driven into the overlapping parts of the two frame strips. With the help of the power output by the linear driver 3, the corner nails arranged in the nail storage groove are always pushed to ensure that there are always corner nails above the nail driving member 14, thereby avoiding interruption of the nailing operation, and realizing the continuity of the corner nailing operation.

[0061] Example 4, refer to Figures 1 to 3, which is the fourth embodiment of the present utility model. On the basis of the angle nailing machine including the workbench 1, the main presser foot 2, and the auxiliary presser foot 3, this embodiment adds a side pressure piece 17 and a rotating piece 18 for large photo frames. Each side pressure piece 17 is provided with a rotating piece 18. When in use, the two frame strips are placed on the workbench 1, aligned with the overlapping area, and then the main presser foot 2 and the auxiliary presser foot 3 are adjusted to press the frame strips; at the same time, the built-in rotating driver 2 of the workbench 1 is started. The rotating driver 2 is preferably an electric-driven motor. The power output by the rotating driver 2 drives one of the side pressure pieces 17 (this side pressure piece 17 is defined as side A, and the other side pressure piece 17 is defined as side B) to rotate, and side A is rotated by corresponding and mutually engaged The teeth drive side B to rotate, and side A and side B are symmetrically distributed on the workbench 1. At the same time, the rotating parts 18 on side A and side B gradually approach the side edges of the two frame bars, and the rotation directions of side A and side B are opposite; until the rotating part 18 is squeezed into contact with the side edges of the frame bar; when the rotating part 18 is squeezed into contact with the frame bar, with the help of the frame bar, the rotating part 18 starts to rotate on the side pressure part 17, and the rotation directions of the rotating part 18 and the side pressure part 17 are opposite; the rotating part 18 is provided with a limiting boss, and when the limiting boss is squeezed into contact with the edge of the side pressure part 17, the rotating part 18 stops swinging. At this time, the angle between the planes on the two swinging parts in contact with the frame bar is ninety degrees, which is suitable for conventional rectangular photo frames.

[0062] The lateral pressure member 17 and the rotating member 18 adjust the overlap angle of the two frame strips to ensure consistency. The rotating member 18 also provides a buffer during rotation, preventing direct impact between the lateral pressure member 17 and the frame strips, thereby preventing damage to the side strip surface quality. The simultaneous contact between the lateral pressure member 17 and the swinging member squeezes and limits the side strips, improving stability during the nailing operation.

[0063] Furthermore, an angle adjusting piece 19 is added; when the Dingding photo frame is not a conventional rectangular photo frame, but a pentagonal or even more polygonal photo frame, the angle adjusting piece 19 is selected to be used, and the swinging piece is adjusted according to the actual situation, and can be selected not to be used; according to the specific overlap angle between two adjacent frame strips on the photo frame, an external force is applied to drive the angle adjusting piece 19 to slide on the side pressure piece 17, and the position of the angle adjusting piece 19 on the side pressure piece 17 is adjusted so that the end of the angle adjusting piece 19 exceeds the end of the side pressure piece 17. When the side pressure piece 17 rotates, the exposed end of the angle adjusting piece 19 is squeezed and contacted with the frame strip, thereby adjusting the angle between the two frame strips, realizing the side squeezing of the frame strip, and combining the main pressure foot 2 and the auxiliary pressure foot 3 to complete the overall fixation of the frame strip, thereby improving the stability of the operation.

[0064] Example 5, refer to Figures 1 to 3, which is the fifth embodiment of the present utility model, the angle nailing machine includes a workbench 1, a main presser foot 2, and an auxiliary presser foot 3. In this embodiment, a fixed angle piece 20 and a fixed angle piece 22 are further added, wherein the fixed angle piece 1 and the fixed angle piece 22 are both detachably arranged on the workbench 1. When working, according to the size of the photo frame model, one of the fixed angle piece 1 and the fixed angle piece 22 is selected for operation. The fixed angle piece 1 suitable for small photo frame operations is taken as an example for explanation. The overlapping area of ​​the two frame strips is just located within the inner corner 1 21. With the help of the inner corner 1 21, the angle of the photo frame corner is limited to ensure the accuracy of the angle.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
