[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figures 1 to 3 , is the first embodiment of the utility model, which provides a technical solution: a feeding mechanism of a target drilling machine, comprising

[0023] The frame 1 is mounted on one side of the feed port of the target drilling machine body 4, and the feeding conveyor belt 2 is installed on the inner side of the frame 1. The frame 1 and the feeding conveyor belt 2 constitute a common belt conveyor, which can be driven by a motor to realize the transportation of materials. The specific structural principles are all existing technologies and will not be described in detail here.

[0024] The two guide limit mechanisms installed on the top of the frame 1 include a limit guide plate 31, two guide posts 32 welded and fixed at both ends of the limit guide plate 31, and a guide seat 33 welded and fixed on the top surface of the frame 1 and corresponding to the guide posts 32. The guide posts 32 movably penetrate the guide seats 33 and can play a guiding and supporting role when the position of the limit guide plate 31 is adjusted subsequently. A center base plate 34 is welded and fixed at the center of the limit guide plate 31, and a U-shaped base 35 that fits the center base plate 34 is welded and fixed on the top surface of the frame 1. A limiting structure is provided between the U-shaped base 35 and the center base plate 34 for limiting the position of the limit guide plate 31 during daily use. The two limit guide plates 31 located at the top of the feeding conveyor belt 2 can effectively guide and limit the PCB to be processed transported on the top of the feeding conveyor belt 2, thereby improving the feeding stability. In the future, the spacing between the two limit guide plates 31 can be adaptively adjusted according to products of different sizes to meet different feeding requirements.

[0025] The top of the limit rod 372 passes through one of the limit holes 373, which can realize stable limitation of the center base 34 and the limit guide plate 31. The limit structure also includes side sliding grooves 374 on the inner walls of both sides of the U-shaped base 35. Side sliding blocks 375 are fixed on both sides of the pressure block 371, and the side sliding blocks 375 slide in the side sliding grooves 374. A reset spring 376 is connected between the top surface of the side sliding block 375 and the inner wall of the top end of the side sliding groove 374. Under the pull of the reset spring 376, the top end of the limit rod 372 can be stably stuck in the limit hole 373 during daily use, ensuring the center base 34 When the locking cam 375 is in the locked state, the locking cam 376 is released and the locking cam 377 is in the locked state, so that the locking cam 377 is in the locked state.

[0026] The top end of the return spring 376 is fixed to the top inner wall of the side sliding groove 374 , and the bottom end of the return spring 376 is fixed to the top surface of the side sliding block 375 .

[0027] A round hole is formed on the top surface of the U-shaped base 35 for the limiting rod 372 to pass through, and a plurality of supporting legs are provided on the bottom of the frame 1 .

[0028] Example 2

[0029] See also Figures 1 to 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but differs in that a rubber plate 36 is installed on the other side surface of the limiting guide plate 31. The rubber plate 36 is made of rubber material and has a soft texture. It can prevent the limiting guide plate 31 from directly contacting the PCB to be processed, thereby playing a protective role. A disassembly structure is provided between the rubber plate 36 and the limiting guide plate 31.

[0030] The disassembly and assembly structure includes two hollow rubber columns 361 arranged on the surface of the rubber plate 36, and the surface of the limiting guide plate 31 is provided with two rectangular through-holes 311 corresponding to the hollow rubber columns 361. The ends of the hollow rubber columns 361 pass through the rectangular through-holes 311, and two limiting rubber heads 362 are provided on the end surface of the hollow rubber columns 361. After the ends of the hollow rubber columns 361 pass through the rectangular through-holes 311, the two limiting rubber heads 362 will be stuck on the other side surface of the limiting guide plate 31, and are used for limiting the position of the hollow rubber columns 361 after they pass through. To ensure the stable installation of the rubber plate 36, the rubber plate 36, the hollow rubber column 361 and the limiting rubber head 362 are an integrated structure and are all made of rubber material. They will undergo elastic deformation when squeezed. When the rubber plate 36 needs to be removed later, it is only necessary to press the hollow rubber column 361 to cause it to undergo elastic deformation and make the limiting rubber head 362 no longer on the other side surface of the limiting guide plate 31. At this time, the hollow rubber column 361 can be pulled out of the rectangular through-hole 311, thereby realizing the rapid removal of the rubber plate 36 and facilitating subsequent disassembly and replacement.

[0031] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
