Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of nail feeding machines, and in particular to a double-station nail cutting mechanism and a nail feeding machine. Background Art

[0002] In the manufacturing industry on the existing market, when assembling structural parts, nailing machines and nail feeders are used in conjunction with each other to automatically realize the screw connection between structural parts. This can effectively save manpower and material resources and improve assembly efficiency.

[0003] In current nail feeding machines, a nail cutting device is provided at the end of the linear track, but the nail cutting device can only take out one nail at a time, which negatively affects the nail feeding efficiency, nailing efficiency and subsequent assembly efficiency. Utility Model Content

[0004] The utility model provides a double-station nail cutting mechanism and a nail feeding machine which can support the removal of two screws at a time, so that the two screws can be tightened simultaneously in one tightening cycle, thereby improving the tightening efficiency and the assembly efficiency.

[0005] In order to solve the above technical problems, the embodiment of the utility model provides a double-station nail cutting mechanism, which is applied to a nail feeding machine. The double-station nail cutting mechanism includes:

[0006] The shell is provided with a screw inlet;

[0007] A first nail cutter is disposed in the housing and is movable relative to the housing to adjust its position relative to the screw feed opening to expose the screw feed opening or to cover the screw feed opening;

[0008] A second nail cutter is disposed in the housing and is movable relative to the housing;

[0009] Among them, the first nail cutter is provided with a first nail removing mechanism, and the second nail cutter is provided with a second nail removing mechanism. When the first nail cutter mechanism moves to the first position, the screw feed opening is blocked. When the first nail cutter mechanism moves to the second position, the screw feed opening is exposed and corresponds to the first nail removing mechanism to achieve the removal and fixation of the screw. When the second nail cutter moves to push the first nail cutter to move to the third position, the second nail removing mechanism corresponds to the screw feed opening to achieve the removal and fixation of the screw.

[0010] As an optional embodiment, the shell includes a bottom shell and a cover plate, the cover plate is detachably connected to the bottom shell, the first nail cutter and the second nail cutter are arranged in the bottom shell, and the screw feed port is opened on the side wall of the bottom shell.

[0011] As an optional embodiment, the first nail cutter further includes a first driver, which is used to drive the first nail cutter to move to the first position or the second position;

[0012] The second nail cutter also includes a second driver, which is used to drive the second nail cutter to move, so that the second nail cutter pushes the first nail cutter to move to a third position, and at the same time makes the second nail removal mechanism correspond to the screw feeding port.

[0013] As an optional embodiment, the first nail cutter structure is elastically connected to the shell. When the first nail cutter structure completes nail removal, the first driver drives the first nail cutter to move from the second position to the first position. When the second nail cutter removes the nail, the second driver drives the second nail cutter to move and pushes the first nail cutter to move to a third position, so that the screw feed port is exposed and corresponds to the second nail removal mechanism. When the second nail removal mechanism completes nail removal, the second driver drives the second nail cutter to reset, and the first nail cutter resets elastically.

[0014] As an optional embodiment, the first nail cutter includes a first body, the first nail removal mechanism includes a first clamping driver mounted on the first body, and a first clamping assembly located in the first body and connected to the first clamping driver, the first body is U-shaped, and its U-shaped opening faces the side of the shell where the screw feed port is opened, so that when the first nail removal mechanism corresponds to the screw feed port, it is connected to the screw feed port, and the first clamping assembly is used to clamp and remove the screw from the screw feed port under the drive of the first clamping driver.

[0015] As an optional embodiment, the first clamping assembly includes two clamping petals that are relatively positioned and rotatably arranged in the first body, and a push block connected to the first clamping driver. When driven by the first clamping driver, the push block can push the two clamping petals to rotate, thereby allowing the two clamping petals to rotate and open and cooperate to clamp the screw located at the screw feed port.

[0016] As an optional embodiment, the two clamping petals are elastically connected at one end away from the screw feeding port, so that the elastically connected ends of the two clamping petals are close to each other, and the other ends for clamping the screws are away from each other;

[0017] The push block is a wedge-shaped push block, and its smaller end is located between one end of the two elastically connected clamping petals. When the push block moves under the drive of the first clamping driver, the length of the push block extending between the two clamping petals is increased, thereby pushing one end of the two elastically connected clamping petals away from each other and the other end closer to each other, thereby clamping and fixing the screw.

[0018] As an optional embodiment, the second nail cutter includes a second body, a second clamping driver, and a second clamping assembly. The second body has the same structure as the first body, the second clamping driver has the same structure as the first clamping driver, and the second clamping assembly has the same structure as the first clamping assembly.

[0019] As an optional embodiment, the double-station nail cutting mechanism further includes:

[0020] The first sensor assembly is used to sense whether there are screws waiting to be fed at the screw feeding port;

[0021] a second sensor assembly, for sensing whether a screw is in place in the first nail cutter or the second nail cutter;

[0022] A controller connected to the first sensor assembly, the second sensor assembly, the first driver, the second driver, the first clamping driver, and the second clamping driver, so as to control the first driver or the second driver to operate to receive the screw when it is determined that there is a screw waiting to be fed at the screw feeding port, and to control the first clamping driver or the second clamping driver to operate to clamp and fix the screw when it is determined that there is a screw in place in the first nail cutter or the second nail cutter;

[0023] The controller is also used to respond to the received target signal and control the first clamping driver or the second clamping driver to operate when the nail removal device is matched and connected with the screw, so as to release the clamping fixation of the screw and allow the nail removal device to remove the screw.

[0024] Another embodiment of the present invention also provides a nail feeding machine, comprising the double-station nail cutting mechanism as described in any one of the embodiments above.

[0025] Based on the disclosure of the above embodiments, it can be known that the beneficial effects of the embodiments of the utility model include being able to simultaneously deliver two screws in one tightening cycle of the nailing machine, thereby improving the nail delivery efficiency, nailing efficiency and subsequent assembly efficiency. Moreover, the first nail cutter and the second nail cutter are both provided with the functions of removing nails and fixing screws. Based on this, when the nail removing device recognizes and extracts the screws, it can effectively avoid the screws rotating together with the nail removing device when recognizing the cap, causing the problem of difficulty in recognizing the cap and a long time for recognizing the cap, thereby improving the efficiency of recognizing the cap and reducing the difficulty of recognizing the cap.

[0040] Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it should be understood that the disclosed embodiments are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant details. Therefore, the specific structural and functional details disclosed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present disclosure in a variety of ways with substantially any suitable detailed structure.

[0041] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0042] Below, the embodiments of the utility model are described in detail with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a double-station nail cutting mechanism, which is applied to a nail feeding machine. The double-station nail cutting mechanism includes:

[0044] The housing 1 is provided with a screw feed port 5, the screw feed port 5 is connected to a screw delivery channel of a nail delivery machine, and a plurality of screws are arranged on the screw delivery channel;

[0045] The first nail cutter 2 is disposed in the housing 1 and can move relative to the housing 1 to adjust its position relative to the screw feed opening 5 to expose the screw feed opening 5 or to cover the screw feed opening 5;

[0046] A second nail cutter 3 is disposed in the housing 1 and is movable relative to the housing 1;

[0047] Among them, the first nail cutter 2 is provided with a first nail removing mechanism, and the second nail cutter 3 is provided with a second nail removing mechanism. When the first nail cutter 2 moves to the first position, the screw feed opening 5 is blocked. When the first nail cutter 2 moves to the second position, the screw feed opening 5 is exposed and corresponds to the first nail removing mechanism to achieve the removal and fixation of the screw. When the second nail cutter 3 moves to push the first nail cutter 2 to move to the third position, the second nail removing mechanism corresponds to the screw feed opening 5 to achieve the removal and fixation of the screw.

[0048] Based on the above content, it can be known based on the disclosure of the above embodiments that the beneficial effects possessed by the embodiments of the utility model include the ability to simultaneously deliver two screws within one tightening cycle of the nailing machine, thereby improving the nail delivery efficiency, nailing efficiency, and subsequent assembly efficiency. Moreover, the first nail cutter 2 and the second nail cutter 3 are both provided with the functions of removing nails and fixing screws. Based on this, when the nail removing device recognizes and extracts the screw, it can effectively avoid the problem that the screw rotates together with the nail removing device when recognizing the cap, causing difficulty in recognizing the cap and a long time for recognizing the cap, thereby improving the efficiency of recognizing the cap and reducing the difficulty of recognizing the cap. Especially for the recognition of hexagonal screws, the solution of this embodiment can effectively solve the problem that the screw rotates together with the nail removing device when recognizing the cap, affecting the recognition of the cap.

[0049] In addition, in this embodiment, by configuring the first nail cutter 2 and the second nail cutter 3 to be movable relative to the housing 1, the moving strokes of the first nail cutter 2 and the second nail cutter 3 can be adjusted, thereby providing a basis for simultaneously extracting two screws within the same tightening cycle without changing the structural dimensions of the original nail feeder. The screw distance can be adjusted, and the problem of limited installation space for the nail cutter in the nail feeder can be solved.

[0050] Combination Figure 1 and Figure 3 As shown, the housing 1 in this embodiment includes a bottom shell and a cover plate 4. The bottom shell can be, for example, a cube with a rectangular cross section, and its upper side is open. The cover plate 4 is detachably connected to the bottom shell to cover the open end of the bottom shell. The first nail cutter 2 and the second nail cutter 3 are arranged in the bottom shell, and the screw feed port 5 is opened on the side wall of the bottom shell. The cover plate 4 is provided with a notch corresponding to the screw feed port 5 to facilitate the screw to be inserted into the corresponding nail cutter.

[0051] The screw in this embodiment is always in a vertical state when located at the feed port, with the nut facing upward, and the screw feed port 5 is T-shaped, matching the shape of the screw, wherein at least the vertical portion is similar in size to the screw, so as to limit the screw and prevent it from tilting or changing its position and shape, which would affect the subsequent successful insertion of the screw.

[0052] Furthermore, the first nail cutter 2 in this embodiment further includes a first driver 6, which is used to drive the first nail cutter 2 to move to the first position or the second position;

[0053] The second nail cutter 3 also includes a second driver 7, which is used to drive the second nail cutter 3 to move, so that the second nail cutter 3 pushes the first nail cutter 2 to move to the third position, and at the same time makes the second nail removal mechanism correspond to the screw feeding port 5.

[0054] For example, the positions to be fed of the first nail cutter 2 and the second nail cutter 3 are the first position and the fourth position respectively. The first nail cutter 2 in the first position blocks the screw feed port 5 so that the screw is limited at the screw feed port 5. When the first nail cutter 2 moves to the second position, the screw feed port 5 is exposed and corresponds to the first nail removal mechanism of the first nail cutter 2, that is, the first nail cutter 2 moves to a position so that the first nail removal mechanism corresponds to the screw feed port 5, thereby exposing the screw feed port 5. At this time, the screw limited at the screw feed port 5 is no longer blocked and will be pushed into the first nail removal mechanism under the action of the travel force of the subsequent screw in the screw delivery channel. The distance between the first nail removal mechanism and the screw feed port 5 is small, and the screw to be inserted only needs a small movement to be inserted, that is, moved into the first nail removal mechanism.

[0055] In order to enable the second nail cutter 3 to smoothly move to the position corresponding to the screw feed opening 5 without increasing the overall size of the nail feeder, in this embodiment, the first nail cutter 2 is elastically connected to the housing 1, for example, the first nail cutter 2 can be connected to the end of the housing 1 away from the second nail cutter 3 through a spring. When the first nail cutter 2 completes the nail removal, the first driver 6 drives the first nail cutter 2 to move from the second position to the first position, that is, drives the first nail cutter 2 to reset. At this time, the screw feed opening 5 is blocked by the first nail cutter 2 again, and the screw to be fed is limited at the screw feed opening 5. At this time, the second nail cutter 3 performs a nail removal operation, for example, the second driver 7 drives the second nail cutter 3 to move from the current fourth position to the direction close to the first nail cutter 2, and pushes the first nail cutter 2 to move in the direction of the compression spring until the first nail cutter 2 moves to the third position, so that the screw feed port 5 is exposed and corresponds to the second nail removal mechanism of the second nail cutter 3. The current position of the second nail cutter 3 is the fifth position, that is, when the second nail cutter 3 is driven to the fifth position, its second nail removal mechanism corresponds to the screw feed port 5, and the nail removal can be completed. When the second nail removal mechanism completes the nail removal, the second driver 7 drives the second nail cutter 3 to reset to the fifth position. As the second nail cutter 3 moves away from the first nail cutter 2, the second nail cutter 3 no longer pushes the first nail cutter 2. At this time, the first nail cutter 2 is reset to the first position under the elastic force of the spring.

[0056] Combination Figure 3 As shown, the first nail cutter 2 in this embodiment includes a first body 8, and the first body 8 has a mounting groove 13. The mounting groove 13 is open toward the side of the housing 1 where the screw feed port 5 is opened and toward the side of the back plate, so that when the first nail removal mechanism corresponds to the screw feed port 5, it is connected with the screw feed port 5 and the notch on the cover plate 4. The first nail removal mechanism includes a first clamping driver 9 installed on the side of the first body 8 away from the screw feed port 5, and its telescopic arm passes through the first body 8 and extends into the mounting groove 13. The first nail removal mechanism also includes a first clamping assembly located in the first body 8 and connected to the telescopic arm of the first clamping driver 9, and the first clamping assembly is used to clamp and remove the screw from the screw feed port 5 under the drive of the first clamping driver 9.

[0057] Specifically, the first clamping assembly in this embodiment includes two clamping flaps 10 that are relatively positioned and rotatably arranged in the first body 8, and a push block 11 connected to the first clamping driver 9. The two clamping flaps 10 can be rotatably arranged in the mounting groove 13 of the first body 8 based on the shaft, wherein the shaft is arranged in the middle of the clamping flaps 10, and the ends of the two clamping flaps 10 away from the screw feed port 5 are elastically connected so that the ends of the two clamping flaps 10 that are elastically connected are close to each other, and the other ends for clamping the screws are away from each other. In actual application, for example, it is possible to choose to set a protrusion on the upper surface of the end of the two clamping flaps 10, and then set and fix an elastic ring 14 on the two protrusions to achieve elastic connection of one end of the two clamping flaps 10 (note that the rear end of the clamping flap 10 is elastically connected). When the nail is not removed, the rear ends of the two clamping flaps 10 are tightened and the front ends are open. The push block 11, driven by the first clamping driver 9, can push the rear ends of the two clamping flaps 10, thereby driving the two clamping flaps 10 to rotate, so that the front ends of the two clamping flaps 10 can rotate and tighten and cooperate to clamp the screws located at the screw feed port 5.

[0058] like Figure 3As shown, the push block 11 in this embodiment is a wedge-shaped push block 11, having a smaller end and a larger end. Of course, it may not be a wedge-shaped push block 11, but a triangular push block 11 or other structures having gradually tightened ends from large to small. The smaller end of the wedge-shaped push block 11 is located between the ends of the two clamping petals 10 that are elastically connected, that is, between the rear ends of the two clamping petals 10. When the first clamping driver 9 is running, the push block 11 is driven by the telescopic arm of the first clamping driver 9 to move, and the length extending between the two clamping petals 10 is increased. Since the push block 11 has a large rear end width, it will push the ends of the two clamping petals 10 that are elastically connected to each other away from each other, while the other ends are close to each other, that is, the front ends of the two clamping petals 10 will be close to each other, so that the screws can be clamped and fixed in the installation slot 13, waiting for the nail removal device to recognize the cap and remove the screws.

[0059] The second nail cutter 3 in this embodiment includes a second body, a second clamping driver, and a second clamping assembly. The second body has the same structure as the first body 8, the second clamping driver has the same structure as the first clamping driver 9, and the second clamping assembly has the same structure as the first clamping assembly. That is, the second nail cutter 3 has the same structure as the first nail cutter 2, so it will not be described in detail.

[0060] In order to automatically control the operation of the first nail cutter 2 and the second nail cutter 3 and ensure that the movement stroke, movement timing and movement position of the first nail cutter 2 and the second nail cutter 3 match the actual required situation, the double-station nail cutting mechanism in this embodiment also includes:

[0061] The first sensor component, the second sensor 12 component and the controller, the controller can be a master controller device in the nail feeding machine, or an independently set controller, such as an embedded chip, etc., the specific details are uncertain.

[0062] The first sensor assembly includes at least two first sensors, which are used to sense whether there are screws waiting to be fed at the screw feed port 5. The first sensors can be arranged near the screw feed port 5, and the specific arrangement position is not fixed.

[0063] The second sensor 12 assembly includes at least two second sensors 12 , which are used to sense whether a screw is in place in the first nail cutter 2 or the second nail cutter 3 , that is, whether the screw is moved and located in the installation slot 13 .

[0064] The controller is connected to the first sensor component, the second sensor 12 component, the first driver 6, the second driver 7, the first clamping driver 9, and the second clamping driver. When the first sensor component determines that there is a screw to be fed at the screw feed port 5, the controller controls the first driver 6 to drive the first nail cutter 2 to move to the second position. At this time, the screw is inserted into the installation slot 13 of the first nail cutter 2. When the second sensor 12 component detects that a screw is in place, the controller controls the first clamping driver 9 to drive the first clamping component to clamp the screw in place, and then controls the first driver 6 to drive the first nail cutter 2 to reset to the first position, so that the first nail cutter 2 completes the nail removal. When the first sensor component determines that the screw is at the screw feed port 5 waiting for feeding, the second driver 7 is controlled to drive the second nail cutter 3 to move to the position corresponding to the screw feed port 5. When the screw is determined to be in place based on the information uploaded by the second sensor 12, the second clamping driver is controlled to run, so that the second clamping component clamps the screw in place, and then the second driver 7 is controlled to drive the second nail cutter 3 to reset. After being reset, the first nail cutter 2 and the second nail cutter 3 are always in a state of clamping and fixing the screws, waiting for the nail removal device to complete the cap recognition. When the controller obtains the signal that the nail removal device has completed the cap recognition, it controls the first clamping driver 9 and the second clamping driver to run to loosen the screws and allow the nail removal device to remove the screws.

[0065] Another embodiment of the present invention also provides a nail feeding machine, comprising the double-station nail cutting mechanism as described in any one of the embodiments above.

[0066] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
