The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figures 1 to 3 The nailing device of the first embodiment of the present invention includes: a lower mold 210 mechanism, including a base 220 and a lower mold 210, the lower mold 210 is provided with a riveting platform 217, the riveting platform 217 is protruding with a round table 213 matching the rivet, the round table 213 protrudes radially to form a plurality of cutters 212, and the plurality of cutters 212 are arranged along the circumference of the round table 213; an upper mold 130 mechanism is arranged on the upper side of the lower mold 210, and the upper mold 130 mechanism drives the rivet to abut against the round table 213 and the cutter 212.

[0027] After the rivet is delivered by a conveying mechanism, such as a vibrating plate, the upper die 130 mechanism drives the rivet to move toward the lower die 210, pressing the rivet down to the round table 213, and the round table 213 bends the edge of the rivet to achieve riveting of the rivet. At the same time, the bent portion is cut by the cutter 212, so that the bent portion is divided into multiple pieces, so that the bent portion can be flattened, reducing the thickness of the bent portion, reducing the thickness of the circuit board, and improving the performance of the circuit board. It should be noted that the conveying mechanism can use a vibrating plate for conveying. The vibrating plate conveying one by one is an existing conventional technology and will not be described in detail here.

[0028] It is understandable that, referring to Figure 2 The lower die 210 is provided with a positioning post 211 and a spring 216. The positioning post 211 is movably provided on the lower die 210. The positioning post 211 passes through the truncated cone 213. One end of the positioning post 211 protrudes from the truncated cone 213 and matches the rivet. The spring 216 drives the positioning post 211 to move upward. The upper die 130 mechanism drives the rivet to abut against the positioning post 211, so that the rivet and the positioning post 211 are sleeved to achieve the positioning of the rivet. After the positioning post 211 abuts the rivet, the upper die 130 mechanism continues to drive the rivet. In order to make the rivet abut against the truncated cone 213, the positioning post 211 moves downward, and the spring 216 is compressed. While achieving positioning, it avoids affecting the contact between the rivet and the truncated cone 213, thereby improving the accuracy of riveting.

[0029] It is understandable that, referring to Figure 2 The positioning post 211 is provided with a first limiting portion 215 protruding radially. The lower side of the first limiting portion 215 abuts against one end of the spring 216. The lower die 210 is provided with a second limiting portion 214. The second limiting portion 214 cooperates with the first limiting portion 215 to limit the travel of the positioning post 211. The abutment of the spring 216 with the first limiting portion 215 enables the spring 216 to smoothly drive the positioning post 211 to move. At the same time, the second limiting portion 214 cooperates with the first limiting portion 215 to limit the upward movement of the positioning post 211, preventing the positioning post 211 from separating from the lower die 210 and improving stability.

[0030] It is understandable that, referring to Figure 4 The base 220 is provided with a cover 221, and the lower die 210 is disposed within the cover 221. The cover 221 has an escape hole for the upper die 130 mechanism, through which the positioning post 211 passes. The base 220 has a waste removal passage 222, which communicates with the interior of the cover 221. The cover 221 protects the lower die 210 from damage and allows the debris generated by the cutter 212 when cutting the rivets to remain within the cover 221, preventing the debris from being scattered. The debris is then removed through the waste removal passage 222, keeping the environment clean.

[0031] It is understandable that, referring to Figure 4The nailing mechanism also includes a base 230. The base 220 is arranged on the base 230. The base 230 has a groove 231. The groove 231 is connected to the waste cleaning channel 222. The groove 231 can be closed and then connected to the external negative pressure air source to continuously remove the debris in the groove 231 and at the same time remove the debris in the waste cleaning channel 222 to avoid clogging the waste cleaning channel 222.

[0032] It is understandable that, referring to Figure 5 The upper mold 130 mechanism includes a driving component and an upper mold 130. The upper mold 130 is arranged on the upper side of the lower mold 210. The driving component drives the upper mold 130 to move toward the lower mold 210. The driving component includes a motor 110 and a transmission member. The motor 110 drives the upper mold 130 to move in the vertical direction through the transmission member.

[0033] Specifically, refer to Figure 5 The transmission part includes a shell 120, in which a guide block 123, a first rotating shaft 122 and a second rotating shaft 121 are arranged. The motor 110 drives the first rotating shaft 122 to rotate, the first rotating shaft 122 is sleeved with the second rotating shaft 121, the first rotating shaft 122 is threadedly connected with the second rotating shaft 121, the second rotating shaft 121 is sleeved with the guide block 123, and a sliding groove 124 matching the guide block 123 is opened in the shell 120, the guide block 123 is slidably connected to the sliding groove 124, and the upper mold 130 is arranged at the lower end of the second rotating shaft 121. The shell 120 protects the guide block 123, the first rotating shaft 122 and the second rotating shaft 121, reducing the risk of damage. The motor 110 drives the first rotating shaft 122 to rotate, and the guide block 123 is slidably connected with the slide groove 124, so that the rotational motion of the first rotating shaft 122 is converted into the linear motion of the second rotating shaft 121. The guide block 123 slides along the slide groove 124, so that the second rotating shaft 121 moves in the vertical direction. At the same time, the motor 110 can realize the rapid movement of the upper mold 130, thereby improving efficiency.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
