[0030] Please see Figures 1 to 6 As shown, this embodiment provides an automatic feeding device for a C-type nail gun. The C-type nail gun 10 includes a guide rod 11 and a retaining spring tab 12. The guide rod 11 is configured to mount at least one C-type nail strip 20. The retaining spring tab 12 is configured to press one end of the C-type nail strip 20 on the guide rod 11. The automatic feeding device for the C-type nail gun includes a base 30 and at least one set of automatic feeding components 40, wherein:

[0031] The automatic feeding assembly 40 includes a hopper assembly 41 and a pusher assembly 42. The hopper assembly 41 is disposed on the base 30. The hopper assembly 41 includes a first drive member 410 and a nail bar hopper 411. The nail bar hopper 411 is provided with a receiving cavity 412 extending along a first direction for storing at least one C-shaped nail bar 20. The drive end of the first drive member 410 is connected to the nail bar hopper 411. The first drive member 410 is configured to drive the nail bar hopper 411 to reciprocate along a second direction, so that the nail bar hopper 411 alternately moves to the first position or the second position. The first direction (X direction in the figure) is perpendicular to the second direction (Y direction in the figure).

[0032] The feeding assembly 42 is disposed on the base 30 and located on one side of the hopper assembly 41. The feeding assembly 42 includes a second driving member 420 and a push rod 421. The driving end of the second driving member 420 is connected to the push rod 421. The second driving member 420 is configured to drive the push rod 421 to reciprocate along a first direction, so that the push rod 421 alternately moves to a third position or a fourth position.

[0033] When the nail bar hopper 411 moves to the first position, it avoids the push rod 421 moving to the third position. When the push rod 421 moves to the third position, the receiving cavity 412 of the nail bar hopper 411 in the second position corresponds to the push rod 421 in the first direction. The drive end of the conveying mechanism (not shown in the figure) is connected to the C-type nail gun 10. The conveying mechanism carries the C-type nail gun 10 to the first preset position of the base 30, so that the guide rod 11, the receiving cavity 412 and the push rod 421 correspond in the first direction. The second drive member 420 drives the push rod 421 to move from the third position to the fourth position, so that at least one C-type nail bar 20 in the receiving cavity 412 is fitted onto the guide rod 11.

[0034] Specifically, the first driving component 410 and the second driving component 420 are either pneumatic cylinders or electric cylinders.

[0035] Specifically, the first position is the initial position of the nail bar hopper 411, the second position is the feeding position of the nail bar hopper 411, the third position is the initial position of the push rod 421, and the fourth position is the end position after the push rod 421 pushes out the nail bar from the nail bar hopper 411.

[0036] Specifically, the first preset position is the feeding position of the C-type nail gun 10. At this time, the guide rod 11, the receiving cavity 412 and the push rod 421 are on the same straight line.

[0037] Specifically, the handling mechanism can be a robotic arm.

[0038] As can be seen, the first driving component 410 drives the nail bar hopper 411 to be pushed from the first position to the second position, so that the discharge port 414 of the receiving cavity 412 is connected to one end of the push rod 421. The second driving component 420 drives the push rod 421 to be pushed from the third position to the fourth position, which can push the nail bar in the nail bar hopper 411 located in the second position to the guide rod 11, realizing the automated supply of nail bar from the nail bar hopper 411 to the C-type nail gun 10, reducing manual intervention and greatly improving the feeding efficiency.

[0039] In one embodiment, the automatic feeding assembly 40 also includes at least one lever 43, which is vertically fixed on the base 30. The lever 43 is configured to cooperate with the conveying mechanism to press the snap ring 12 against the pressing end of the C-shaped nail strip 20 on the guide rod 11.

[0040] Specifically, the transport mechanism transports the C-type nail gun 10 to the second preset position of the base 30, causing the snap ring 12 to interfere with the guide rod 11 in the first direction. The transport mechanism then drives the C-type nail gun 10 to move along the first direction, causing the snap ring 12 to move close to the pressing end of the C-type nail bar 20 on the guide rod 11 and press against the pressing end.

[0041] Specifically, the second preset position is the paddle position of the C-type nail gun 10, at which time the snap ring paddle 12 is located on the rear side of the guide rod 11.

[0042] As can be seen, the lever 43 is vertically fixed on the base 30 and is used to cooperate with the conveying mechanism to press the snap ring 12 onto the pressing end of the C-shaped nail strip on the guide rod 11, ensuring that the C-shaped nail strip is fixed on the guide rod 11, preventing the nail strip from loosening or falling off during subsequent use, and ensuring the normal operation of the C-shaped nail gun.

[0043] In one implementation, two levers 43 are provided, which are spaced apart along the first direction, and the two levers 43 correspond to the two ends of the retaining spring plate in the first direction, respectively. 。

[0044] Specifically, the gap between the two levers 43 is greater than the width of the C-shaped nail guide groove.

[0045] It can be seen that the two levers 43 cooperate with the conveying mechanism to move the snap ring 12 to the back of the nail bar and press it tightly, which further ensures the efficiency of the snap ring 12 and improves the stability and reliability of the feeding device.

[0046] In one embodiment, the nail bar hopper 411 is also provided with a clearance groove 413 located on one side of the receiving cavity 412. The clearance groove 413 is connected to the receiving cavity 412 and extends along the second direction. The clearance groove 413 is configured to avoid the push rod 421 in the second direction.

[0047] Specifically, the inner side of the clearance groove 413 is symmetrically chamfered.

[0048] Specifically, a limiting surface is provided on the other side of the receiving cavity 412 along the first direction, one end of the nail bar abuts against the limiting surface, and the other end of the nail bar is provided at the discharge port 414.

[0049] Specifically, the silo shell can be semi-transparent. By changing the material of the silo shell, the conventional silo shell can be changed into a transparent silo shell, making it easier for personnel or vision to intuitively determine whether there is material.

[0050] It is evident that the arrangement of the receiving cavity 412, the discharge port 414, and the clearance groove 413 is adapted to the workflow of the entire automatic feeding device. The nail strips are stably stored in the receiving cavity 412. After being pushed to the feeding station by the first driving component 410, the push rod 421 can smoothly push the nail strips out of the discharge port 414 through the clearance groove 413, realizing the orderly supply of nail strips and improving the working efficiency and reliability of the feeding device.

[0051] In one embodiment, the push rod 421 has an overall "L" shaped structure. The push rod 421 includes a fixing part and a push part. The first end of the fixing part is fixedly installed on the moving end of the second driving member, and the push part is vertically arranged at the second end of the fixing part.

[0052] As can be seen, the push rod 421 has a simple structure, and the installation method of the fixing part and the second driving component 420 is clear, which facilitates the installation and disassembly of the push rod 421. During equipment maintenance and repair, the push rod 421 can be easily inspected and replaced, reducing the maintenance cost and difficulty of the equipment and improving the maintainability of the equipment.

[0053] In one implementation, at least two sets of automatic feeding components 40 are provided, and the at least two sets of automatic feeding components 40 are arranged parallel to each other on the base 30 along the first direction.

[0054] As can be seen, the automatic feeding device for the C-type nail gun 10 is equipped with three sets of equidistant parallel automatic feeding components 40, which can simultaneously feed multiple C-type nail guns 10 or provide more C-type nail strips 20 to a C-type nail gun 10 in a short period of time, greatly improving the feeding capacity. In high-demand production environments, it can meet the needs of rapid and large-volume feeding and improve overall production efficiency.

[0055] In one embodiment, the snap ring paddle 12 includes a paddle 120, a limiting plate 121, and a coil spring 122. The limiting plate 121 is mounted on the gun body of the C-type nail gun 10 extending in a second direction. The paddle 120 is slidably disposed on the limiting plate 121. The first end of the coil spring 122 is fixed to the gun body, and the second end of the coil spring 122 is connected to the paddle 120.

[0056] As can be seen, the paddle 120 of the snap ring 12 can reciprocate along the second direction. The abutting end of the paddle 120 abuts against the C-shaped nail bar 20 on the guide rod 11. The coil spring 122 can drive the paddle 120 to reset along the limiting plate 121, pushing the abutting C-shaped nail bar 20 to the working end of the C-shaped nail gun 10. This realizes the automatic pushing of the C-shaped nail bar 20 on the guide rod 11, ensuring that the C-shaped nail gun 10 can continuously and stably acquire the C-shaped nail bar 20 during operation, thus improving the working efficiency and continuity of the C-shaped nail gun 10.

[0057] The working principle of the above-mentioned C-type nail gun automatic feeding device is as follows:

[0058] The robotic arm controls the working position and feeding position of the C-type nail gun 10. When the robotic arm controls the C-type nail gun 10 to the feeding position, the first drive unit 410 pushes the nail strip hopper 411 to connect with the guide rod 11. The second drive unit 420, in conjunction with the push rod 421, pushes the nail strips located in the nail strip hopper 411 onto the guide rod 11. The robotic arm moves the retaining spring lever 12 to the rear side of the lever 43, and then drives the C-type nail gun 10 to move along the first direction, moving the retaining spring lever 12 to the rear side of the nail strip. The retaining spring lever 12 controls the automatic feeding of the nail strips on the guide rod 11. The robotic arm controls the C-type nail gun 10 to leave, completing the automatic installation.
