[0041] Specifically, at least one of the pin shaft structures 20 is connected to the mounting plate 10. The driving mechanism 30 is provided on the plurality of pin shaft structures 20, and the driving mechanism 30 drives the plurality of pin shaft structures 20 to rotate. The first adjustment mechanism 40 is provided on the mounting plate 10, and the first adjustment mechanism 40 adjusts the relative positions of the plurality of pin shaft structures 20 in a first direction. The second adjustment mechanism 50 is provided on the mounting plate 10, and the second adjustment mechanism 50 adjusts the relative positions of the plurality of pin shaft structures 20 in a second direction, and the first direction and the second direction are different.

[0042] In other words, see Figures 1 to 5 The variable pitch rotation device 100 according to the embodiment of the present invention is mainly composed of a mounting plate 10, a plurality of pin shaft structures 20, a driving mechanism 30, a first adjustment mechanism 40 and a second adjustment mechanism 50. Figure 1 and Figure 5 As shown, at least one of the plurality of pin shaft structures 20 is connected to the mounting plate 10, and the pin shaft structure 20 is used as a reference to facilitate the relative position adjustment of other pin shaft structures 20 relative to the pin shaft structure 20. Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the driving mechanism 30 is installed on multiple nail shaft structures 20, and the driving mechanism 30 can drive multiple nail shaft structures 20 to rotate at the same time, so as to adjust the position angle of the nail shaft structure 20. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the first adjustment mechanism 40 is mounted on the mounting plate 10, and the first adjustment mechanism 40 can adjust the relative positions of the plurality of nail shaft structures 20 in the first direction. Figures 2 to 5As shown, the second adjustment mechanism 50 is installed on the mounting plate 10, and the second adjustment mechanism 50 can adjust the relative positions of the multiple nail shaft structures 20 in the second direction. The multiple nail shaft structures 20 are controlled by the first adjustment mechanism 40 and the second adjustment mechanism 50 to achieve variable pitch, and multiple positions can be positioned at the same time, which is convenient for adjusting the spacing between the multiple nail shaft structures 20, thereby realizing a multi-axis synchronous operation mode and effectively improving work efficiency. Among them, the directions of the first direction and the second direction are different. In the present invention, if Figure 1 As shown by the direction of the middle arrow, the first direction may be the X-axis direction, and the second direction may be the Y-axis direction.

[0043] Therefore, according to the variable pitch rotation device 100 of the embodiment of the present invention, multiple nail shaft structures 20 are provided at the same time, and the multiple nail shaft structures 20 are driven to rotate by the driving mechanism 30. And the multiple nail shaft structures 20 are controlled by the first adjustment mechanism 40 and the second adjustment mechanism 50 to achieve variable pitch, and multiple positions can be positioned at the same time, so that the position angles and spacings of the multiple nail shaft structures 20 can be adjusted, thereby realizing a multi-axis synchronous operation mode and effectively improving work efficiency.

[0044] Of course, in the present invention, the variable pitch rotating device 100 can not only be used for inserting and removing nails, but also for the variable pitch and rotation functions required in the process of taking and discharging materials. The variable pitch function can adjust the spacing of materials, and the rotation function can adjust the position angle of materials.

[0045] According to one embodiment of the present invention, a plurality of nail shaft structures 20 are arranged on a first side of a mounting plate 10, a first adjustment mechanism 40 and a second adjustment mechanism 50 are arranged on a second side of the mounting plate 10, a slide rail 11 extending along a first direction is provided on the mounting plate 10, the first adjustment mechanism 40 drives the nail shaft structure 20 to slide along the slide rail 11, and the second adjustment mechanism 50 is directly connected to the nail shaft structure 20.

[0046] That is to say, Figure 1 and Figure 2 As shown, a plurality of pin shaft structures 20 are mounted on the first side of the mounting plate 10, and a first adjustment mechanism 40 and a second adjustment mechanism 50 are mounted on the second side of the mounting plate 10. The first side and the second side of the mounting plate 10 are opposite sides in the thickness direction of the mounting plate 10. A slide rail 11 is provided on the mounting plate 10, and the slide rail 11 extends along a first direction. The first adjustment mechanism 40 drives the pin shaft structure 20 to slide along the slide rail 11, so that the pin shaft structure 20 can change the distance in the first direction. The second adjustment mechanism 50 is directly connected to the pin shaft structure 20, and the second adjustment mechanism 50 realizes the distance change of the pin shaft structure 20 in the second direction. By controlling the first adjustment mechanism 40 and the second adjustment mechanism 50 to realize the distance change of the pin shaft structure 20, multiple positions can be positioned at the same time, which is convenient for adjusting the distance between multiple pin shaft structures 20, thereby realizing a multi-axis synchronous operation mode and effectively improving work efficiency.

[0047] According to an embodiment of the present invention, a plurality of load mounting blocks 12 are disposed on the slide rail 11 , each of the pin shaft structures 20 corresponds to a load mounting block 12 , and the first adjustment mechanism 40 is connected to the load mounting block 12 .

[0048] In other words, Figure 1 and Figure 5 As shown, a plurality of load mounting blocks 12 are mounted on the slide rail 11, and each of the other pin shaft structures 20 except the pin shaft structure 20 directly connected to the mounting plate 10 corresponds to a load mounting block 12. The first adjustment mechanism 40 is connected to the load mounting block 12, and the load mounting block 12 is driven to move along the slide rail 11 by the first adjustment mechanism 40, thereby driving the pin shaft structure 20 to move its position, thereby realizing the variable distance between the plurality of pin shaft structures 20.

[0050] In other words, Figure 1 and Figure 5 As shown, the plugging shaft structure 20 can be set to three, and the three plugging shaft structures 20 can be arranged in a row. The plugging shaft structure 20 located in the middle is connected to the mounting plate 10, and the other plugging shaft structures 20 are based on the plugging shaft structure 20 located in the middle. The two plugging shaft structures 20 located on both sides are respectively connected to the first adjustment mechanism 40 through a load mounting block 12. And the second adjustment structure is respectively connected to the two plugging shaft structures 20 located on both sides. The first adjustment mechanism 40 and the second adjustment mechanism 50 respectively drive the two plugging shaft structures 20 located on both sides to change the pitch relative to the plugging shaft structure 20 located in the middle, and three positions can be positioned at the same time. After the pitch change is completed, the three plugging shaft structures 20 can be driven by a driving mechanism 30 to rotate. This motion characteristic can change the single-axis operation mode in the prior art to a three-axis synchronous operation mode, greatly improving the work efficiency. In the following embodiments of the present invention, three plugging shaft structures 20 are mainly used for specific description to describe the variable pitch rotation device 100 in the present invention. Of course, in the variable pitch rotation device 100 of the present invention, the specific number of the nail shaft structures 20 can be set according to actual needs and will not be described in detail in the present invention.

[0051] According to one embodiment of the present invention, the driving mechanism 30 includes a first driving motor 31 , a first synchronous wheel 32 , a tensioning wheel 33 and a first synchronous belt 34 .

[0053] That is to say, Figure 1 , Figure 2 and Figure 5 As shown, the driving mechanism 30 is mainly composed of a first driving motor 31, a first synchronous wheel 32, a tensioning wheel 33 and a first synchronous belt 34. For the convenience of description, the present invention takes the variable pitch rotating device 100 of three nailing shaft structures 20 as an example for specific description. The first driving motor 31 is installed on the top of the nailing shaft structure 20. The first driving motor 31 can be a rotary motor. Each first synchronous wheel 32 is respectively installed on the corresponding nailing shaft structure 20, and the first driving motor 31 is connected to the first synchronous wheel 32 to drive the first synchronous wheel 32 to rotate. Two tensioning wheels 33 are respectively installed on the nailing shaft structures 20 located on both sides.

The first driving motor 31, the first synchronous wheel 32, the tensioning wheel 33 and the first synchronous belt 34 cooperate with each other to drive the nailing shaft structure 20 to rotate during the nailing process to ensure the nailing effect.

[0054] According to an embodiment of the present invention, the driving mechanism 30 further includes an elastic member 35 , one end of the elastic member 35 is connected to the nail shaft structure 20 , and the other end of the elastic member 35 is connected to one of the tensioning wheels 33 .

A tension spring screw 37 is installed at the rear end of the two nail shaft structures 20. One end of the elastic member 35 (tension spring) can be connected to the nail shaft structure 20 through the tension spring screw 37, and the other end is connected to one of the tension wheels 33. Under the tension of the tension spring, it can be ensured that the nail shaft structure 20 changes pitch in the X and Y directions while the rotating synchronous belt (first synchronous belt 34) and the rotating synchronous wheel (first synchronous wheel 32) are always in meshing state, ensuring that the nail shaft structure 20 can be controlled to rotate while changing pitch.

[0056] According to one embodiment of the present invention, the driving mechanism 30 also includes: a positioning wheel 36, which is arranged on a pin shaft structure 20 located in the middle, the positioning wheel 36 is connected to the first synchronous belt 34, and the positioning wheel 36 is connected to another tensioning wheel 33 through an elastic member 35.

[0057] That is to say, Figure 1 , Figure 4 and Figure 5 As shown, the driving mechanism 30 also includes a positioning wheel 36, which is installed on a central pin shaft structure 20, connected to the first synchronous belt 34, and connected to another tensioning wheel 33 via an elastic member 35. Two of the four elastic members 35 (tension springs) are connected to the tensioning wheels 33 and the tension spring screws 37 on the pin shaft structures 20 on both sides, and the other two are connected to the tensioning wheels 33 and the positioning wheel 36 of the central pin shaft structure 20, to control the pin shaft structure 20 to rotate.

[0058] Of course, in the present invention, structures such as belts, chains and sprockets can also be used to replace the first synchronous belt 34 and the first synchronous wheel 32. As long as the design can realize the rotation of the motor-driven nail shaft structure 20, it should fall within the protection scope of the present invention.

[0059] According to one embodiment of the present invention, the first adjustment mechanism 40 includes a second drive motor 41 and a first adjustment member 42. Specifically, the second drive motor 41 is disposed on the mounting plate 10. One end of the first adjustment member 42 is connected to the second drive motor 41, and the other end of the first adjustment member 42 is connected to the load mounting block 12.

[0060] In other words, the first adjustment mechanism 40 is mainly composed of a second drive motor 41 and a first adjustment member 42, wherein the second drive motor 41 is mounted on the mounting plate 10. One end of the first adjustment member 42 can be directly connected to the second drive motor 41. The other end of the first adjustment member 42 can be connected to the load mounting block 12. The first adjustment member 42 can be a screw rod, which is driven by the second drive motor 41 to drive the screw rod to move, drive the load mounting block 12 to move along the slide rail 11, and then drive the plugging shaft structure 20 to move, thereby realizing the variable pitch of the plugging shaft structure 20.

[0061] In some specific embodiments of the present invention, the first adjusting mechanism 40 includes a second driving motor 41 , a first adjusting member 42 , a second synchronous wheel 43 and a second synchronous belt 44 .

[0062] Specifically, the second synchronous wheels 43 are respectively arranged on the second driving motor 41 and the second synchronous wheels 43. The second synchronous belt 44 connects the two second synchronous wheels 43. One end of the first adjusting member 42 is connected to the second synchronous wheel 43, and the other end is connected to the load mounting block 12.

[0063] That is to say, Figure 1 , Figure 2 and Figure 5 As shown, the first adjustment mechanism 40 is mainly composed of a second drive motor 41, a first adjustment member 42, a second synchronous wheel 43 and a second synchronous belt 44. Among them, the second synchronous wheel 43 is respectively installed on the second drive motor 41 and the second synchronous wheel 43.

The first adjustment member 42 can adopt a tension spring, one end of the first adjustment member 42 is connected to the second synchronous wheel 43, and the other end of the first adjustment member 42 is connected to the load mounting block 12. The two nail shaft structures 20 located on both sides correspond to a set of second drive motor 41, first adjustment member 42, second synchronous wheel 43 and second synchronous belt 44, respectively, to form two sets of Y-direction adjustment mechanisms, thereby realizing the Y-direction pitch change of the nail shaft structure 20.

[0064] According to one embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, there are two second drive motors 41 and two first adjusting members 42. The two second drive motors 41 are arranged opposite to each other, and the two first adjusting members 42 are arranged opposite to each other. Second synchronous wheels 43 are respectively installed on the second drive motor 41 and the first adjusting members 42 located on the same side, and the second synchronous wheels 43 on the second drive motor 41 and the first adjusting members 42 located on the same side are connected by a second synchronous belt 44, thereby forming two sets of X-axis adjustment mechanisms, thereby realizing X-axis pitch variation of the nail shaft structure 20.

[0065] According to one embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the two sets of X-axis adjustment mechanisms in the first adjustment mechanism 40 are respectively installed on opposite sides of the mounting plate 10. The second adjustment mechanism 50 is installed in the middle position of the mounting plate 10.

[0066] In summary, according to the variable pitch rotation device 100 of the embodiment of the present invention, multiple nail shaft structures 20 are provided at the same time, and the multiple nail shaft structures 20 are driven to rotate by the driving mechanism 30. And the multiple nail shaft structures 20 are controlled by the first adjustment mechanism 40 and the second adjustment mechanism 50 to achieve variable pitch, and multiple positions can be positioned at the same time, which is convenient for adjusting the position angle and spacing of the multiple nail shaft structures 20, thereby realizing a multi-axis synchronous operation mode and effectively improving work efficiency. The present invention can realize the action requirements of multi-axis variable pitch and rotating nails, improve the efficiency of nailing, and ensure the tightness of the nails and the nail openings.

[0067] Of course, for those skilled in the art, other structures and working principles of the variable pitch rotation device 100 are understandable and achievable, and will not be described in detail in the present invention.

[0068] According to a second aspect of an embodiment of the present invention, a nailing device is provided, comprising the variable pitch rotating device 100 in the above embodiment. Figures 1 to 5 Taking the three-axis pitch change as an example, the pitch change rotation device 100 is the main structure of the nailing equipment, installed on the three-axis mechanical structure of the gantry, and then equipped with a visual positioning system, a side distance system, a nail feeding system and a matching product positioning structure to form a complete nailing equipment. The three sets of nailing shaft structures 20 installed in the present invention can achieve three-axis high-precision positioning of the nails according to the coordinates provided by the visual positioning system under the action of the adjustment motor, and the function of the three-axis synchronous rotation can ensure the reliability of the nailing action process.

[0069] After the nail-plugging shaft structure 20 has finished taking nails under the drive of the three-axis mechanical structure of the gantry, it receives the coordinate signal of the visual system, and then the variable pitch rotating device 100 of the present invention starts to move. Taking the middle nail-plugging shaft structure 20 as the reference, the X-adjusting motor structure (first adjusting mechanism 40) first drives the second synchronous wheel 43 and the second synchronous belt 44 to drive the screw rod (first adjusting member 42) to drive the nail-plugging shaft structures 20 on both sides to move in the X direction, and at the same time, the Y-adjusting motor structure (second adjusting mechanism 50) directly drives the screw rod (second adjusting member 52) to move in the Y direction. After the X and Y coordinate positions move to the right position, the downward pressing nail-plugging action is started under the action of the Z axis of the three axes of the gantry. At the same time, the rotating motor component (first driving motor 31) drives the rotating synchronous belt (first synchronous belt 34) and the rotating synchronous wheel (first synchronous wheel 32), thereby driving the three nail-plugging shaft structures 20 to rotate at the same time, realizing the downward pressing and rotating nail-plugging action. The nailing device of the present invention can control multiple nailing shaft structures 20 to achieve variable pitch, can simultaneously locate multiple positions, and is convenient for adjusting the position angles and spacings of multiple nailing shaft structures 20, thereby realizing a multi-axis synchronous operation mode and effectively improving work efficiency. The nailing device can realize the action requirements of multi-axis variable pitch and rotating nailing, and can improve the efficiency of nailing and the tightness between the nailing and the nailing opening.

[0070] Of course, for those skilled in the art, other structures and working principles of the nailing device are understandable and achievable, and will not be described in detail in the present invention.

[0071] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
