Hardware products are of various types and specifications, and play an irreplaceable role in home decoration. Choosing good hardware accessories can make many decorative materials safer and more convenient to use.

[0003] In traditional hardware production and processing, a robotic arm device is used to drill holes in the hardware. In the process of the robotic arm device drilling holes in the hardware, hardware debris will fall and accumulate on the work surface.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes an adjusting displacement mechanism 4 and a fixing mechanism 5. The first mounting frame 21 is provided with an adjusting displacement mechanism 4, and the adjusting displacement mechanism 4 includes a bearing 41, a screw rod 42 and a knob 43. The left part of the first mounting frame 21 is fixedly connected with the bearing 41, and the screw rod 42 is rotatably connected to the bearing 41, and the screw rod 42 is threadedly connected to the limit frame 32; the front end of the screw rod 42 is fixedly connected with a knob 43 for rotating the screw rod 42; the drill bit 103 is provided with a fixing mechanism 5, and the fixing mechanism 5 includes a second mounting frame 51, a fixing member 52 and a second elastic member 53. The lower part of the drill bit 103 is fixedly connected with the second mounting frame 51, and the fixing member 52 is slidably connected to the second mounting frame 51 up and down, and the fixing member 52 is made of hard rubber. Four second elastic members 53 are connected between the second mounting frame 51 and the fixing member 52 through spring seats.

[0030] like Figure 1 , Figure 7 and Figure 8 As shown, the automatic forward movement mechanism 6 is also included. The first mounting frame 21 is provided with the automatic forward movement mechanism 6. The automatic forward movement mechanism 6 includes a lower pressure rod 331, a third mounting frame 61, a second rotating shaft 62, a large gear 63, a small gear 64, a vertical rack 66, a third guide rod 65 and a third elastic member 67. The lower pressure rod 331 is fixedly connected to the fixed rod 33. The upper part of the first mounting frame 21 is connected to the third mounting frame 61. The front part of the third mounting frame 61 is rotatably connected to the second rotating shaft 62. The left and right sides of the second rotating shaft 62 The first mounting frame 21 is connected to a large gear 63, which is meshed with the horizontal rack 231 respectively.

The lower part of the first mounting frame 21 is symmetrically connected to two third guide rods 65 on the left and right sides. The third guide rods 65 on the same side are slidably connected to a vertical rack 66, which is in an inverted L shape. A third elastic member 67 is connected between the third guide rod 65 and the vertical rack 66 through a spring seat.

[0031] When the present invention is to be used, first place the hardware that needs to be drilled on the four workstations, then turn on the laser assembly 321, and rotate the laser assembly 321 so that the laser emitted by the laser assembly 321 is located on the hole position that needs to be drilled on the hardware, so that the present invention can accurately locate the hole position that needs to be drilled; drive the mechanical arm assembly 101, and the mechanical arm assembly 101 will move forward with the drilling assembly 102 and the drill bit 103 to the top of the hardware that needs to be drilled. At this time, the tail end of the laser emitted by the drill bit 103 and the laser assembly 321 is located on the same vertical line, and the mechanical arm assembly 101 will press down with the drilling assembly 102 and the drill bit 103. At the same time, the fixing rod 33, the pressing rod 331 and the fixing mechanism 5 will also be moved forward. When the pressing rod 331 contacts the vertical rack 66, the pressing rod 331 will press down with the vertical rack 66, and the third elastic member 67 will be compressed. During the pressing process of the vertical rack 66, it will contact and mesh with the pinion 64 and rotate clockwise with the gear teeth of the pinion 64. During this process, the rotating shaft 62 will not rotate. When the fixing rod 33 contacts the limiting frame 32, the fixing rod 33 will follow the inclined surface of the limiting block to enter the bottom of the limiting frame 32, so that the drill bit 103 will not deviate, thereby enabling the device to achieve accurate drilling of hardware. When the fixing part 52 contacts the surface of the hardware, the mechanical arm assembly 101 continues to move downward, and the second mounting frame 51 will be fixed on the fixing part. When the drill bit 103 contacts with the hardware and drills a hole thereon, the hardware will vibrate and move. When the fixing member 52 contacts with the surface of the hardware, it will apply force to it, thereby fixing the hardware so that it will not vibrate and move significantly, thereby ensuring the accuracy of the drilling position. After the drilling of the first hole is completed, the mechanical arm assembly 101 will move up with the drilling assembly 102 and the drill bit 103, and the lower pressure rod 331 will also move up together. At this time, the third elastic member 67 loses the force to compress it, and thus it will rebound together with the vertical rack 66. Reset, when the vertical rack 66 is in contact with the pinion 64 during the upward movement, the vertical rack 66 will drive the gear teeth of the pinion 64 to rotate counterclockwise, and at the same time, the gear teeth of the pinion 64 will drive the ratchet inside the pinion 64 to rotate together, thereby driving the shaft 62 to rotate together, and when the shaft 62 rotates, it will drive the large gear 63 to rotate, and when the large gear 63 rotates, it will drive the mounting plate 23 forward through the horizontal rack 231, and when the mounting plate 23 moves forward, the first elastic member 24 will be compressed, and at the same time, the push plate 25 will also move forward together, and push the debris on the work surface forward to clean it, so that the present invention can automatically clean the work surface, greatly improving the pass rate when producing hardware;When the vertical rack 66 is disengaged from the pinion 64, the pinion 64 loses the force to drive it to rotate, and the first elastic member 24 will rebound and reset with the mounting plate 23. At the same time, the horizontal rack 231 will also move backward and reset. When the horizontal rack 231 moves backward, it will reset the shaft 62 and the large gear 63 together. Turn the knob 43, the knob 43 will rotate with the screw rod 42. When the screw rod 42 rotates, the limit frame 32 will move backward on the screw rod 42 and the second guide rod 31. When the knob 43 is rotated once, the limit frame 32 will move backward a fixed distance, so that the present invention can ensure that the distances between the holes drilled on the hardware are equal and it is not easy to produce errors according to this characteristic. In the subsequent work, the mechanical arm assembly 101 is driven to rotate to the other three stations, and the above steps are repeated. After the work is completed, the device is closed and cleaned. ;

[0032] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
