Technical Field

[0002] A circuit board punching machine, also known as a PCB punching machine, is a device specially designed for use in the manufacturing process of electronic printed circuit boards. The main function of a circuit board punching machine is to punch holes on a PCB so that components can be inserted or circuits can be connected at appropriate locations. These holes can be used to insert electronic components, solder pins, connect wires, etc. It is an indispensable step in the circuit board manufacturing process.

[0003] As a necessary part of various electrical equipment, circuit boards need to be punched during processing, and a punching machine is needed for punching. In the process of punching, the punching needle needs to rise after passing through the circuit board. If the friction between the punching needle and the circuit board is too large during the rising process, the punching needle will drive the circuit board to rise, and the circuit board will be carried. The operator also needs to manually remove the circuit board, which reduces the efficiency of punching the circuit board. To this end, we propose a punching machine for circuit board processing.

A blocking rod 2110 is fixedly installed inside the punching machine body 11, and one end of the blocking rod 2110 penetrates into the inner cavity of the mounting frame 13 and contacts with the top of the movable block 2108.

By setting an automatic disengagement unit 21, it is possible to avoid the phenomenon of the punching needle 2107 carrying the board during the rising process, and the operator does not need to manually remove the circuit board, thereby ensuring the separation effect between the punching needle 2107 and the circuit board, and at the same time increasing the efficiency of punching the circuit board; The inner cavity of the mounting mold 2103 is provided with a groove 2117, and the number of the grooves 2117 is two.

[0023] The specific implementation of this embodiment is as follows: when the user needs to punch a circuit board, the user installs the required mounting die 2103 on the mounting frame 13 through the hexagonal bolt 2105 and the mounting plate 2104. The user can install different mounting dies 2103 through the hexagonal bolt 2105 and the mounting plate 2104, so as to adapt to different circuit board punching requirements. At this time, the user places the circuit board on the workbench of the punching machine body 11, and uses the external control switch and power supply to start the electric telescopic rod 2101. The start of the electric telescopic rod 2101 drives the extrusion rod 2102 to move, so that the extrusion rod 2102 2 is exposed. At this time, the user uses the control box 12 to start the punching machine body 11, and the hydraulic cylinder in the punching machine body 11 drives the mounting frame 13 to move. The movement of the mounting frame 13 drives the mounting mold 2103 to move. The movement of the mounting mold 2103 drives the movable block 2108 to move. The movement of the movable block 2108 drives the punching needle 2107 to move, so that the punching needle 2107 punches the circuit board. When the mounting mold 2103 is about to move to the position of the circuit board, the extrusion rod 2102 enters the inner cavity of the mounting mold 2103 through the through hole 2106, so as to squeeze the limit block 2109. The bottom of the limit block 2109 is arranged in an inclined surface. When the limit block 2109 is squeezed by the squeezing rod 2102, it will move. The movement of the limit block 2109 drives the dovetail block 2112 to move in the inner cavity of the dovetail groove 2116, and at the same time squeezes the first spring 2111, so that the limit block 2109 is separated from the limit of the movable block 2108. At this time, the reaction force of the tension spring 2115 drives the sliding sleeve 2113 to move on the surface of the sliding rod 2114, and the movement of the sliding sleeve 2113 drives the movable block 2108 to move, and the movement of the movable block 2108 drives the punching needle 2107 to move, so that the punching needle 2107 07 moves into the inner cavity of the installation mold 2103. At this time, the installation mold 2103 contacts the circuit board to position the circuit board, and the punching needle 2107 can be separated from the circuit board first. After the punching needle 2107 completely enters the inner cavity of the installation mold 2103, the hydraulic cylinder inside the punching machine body 11 moves the mounting frame 13 to the original position to complete the punching of the circuit board, thereby avoiding the phenomenon of the punching needle 2107 carrying the board during the rising process. The operator does not need to manually remove the circuit board, which ensures the separation effect between the punching needle 2107 and the circuit board, and at the same time increases the efficiency of punching the circuit board.

Each group of nozzles 306 is sleeved on the surface of each group of smear rods 2218. One end of the smear rod 2218 contacts the bottom of the oil outlet shell 305. The input end of the extruder 303 is fixedly connected to an oil suction pipe 304. The top of the movable block 2108 is provided with a refueling port, which is connected to the oil box 302. The inner cavity plunger of the refueling port has a cover 301. By setting the refueling port and the cover 301 in cooperation, it is convenient for the user to add liquid lubricating oil into the oil box 302. By setting up the lubrication unit 22 and the oil injection mechanism 3 for use together, the punching needle 2107 can be lubricated during the process of punching the circuit board. The operator no longer needs to manually apply lubricating oil to the surface of the punching needle 2107. At the same time, the lubrication effect between the punching needle 2107 and the circuit board can be ensured, and the punching effect and quality during punching can be ensured. At the same time, during the rising process of the punching needle 2107, the friction between the punching needle 2107 and the circuit board can be reduced, so that the circuit board and the punching needle 2107 can be better separated, thereby further ensuring the punching efficiency.

[0026] The specific implementation of this embodiment is as follows: after punching of the circuit board is completed, the mounting frame 13 is driven to rise by the punching machine body 11. During the rising process, since the movable block 2108 rises due to the reaction force of the tension spring 2115, there is a certain space between the movable block 2108 and the mounting mold 2103. During the rising process of the movable block 2108, the shell 2205 is driven to move. Through the reaction force of the second spring 2215, the movable plate 2216 is kept in the original position, the connecting rod 2210 is also kept in a stationary state, and the support plate 2211 is also kept in a stationary state. When the movable block 2108 is completely moved to the required position, and the punching needle 2107 is also completely entered into the inner cavity of the mounting mold 2103, the smear rod 2218 is When the mounting frame 13 is raised, the mounting mold 2103 is driven to move, and the movement of the mounting mold 2103 drives the movable block 2108 to move. When the gear 2203 is meshed with one of the tooth plates 2223, the gear 2203 is driven by the tooth plate 2223 to rotate a certain angle. When the mounting frame 13 continues to rise, the rotation of the gear 2203 drives the rotating rod 2202 to rotate, and the rotation of the rotating rod 2202 drives the multiple telescopic rod 2208 to rotate. The multiple telescopic rod 2208 rotates through the first bearing 2204. At the same time, the multiple telescopic rod 2208 drives the transmission rod 2207 to move during the rotation process. The movement of the transmission rod 2207 passes through the transmission groove 220 9 drives the transmission plate 2206 to move, the movement of the transmission plate 2206 drives the shell 2205 to move, the movement of the shell 2205 drives the guide sleeve 2214 to move on the surface of the guide rod 2213, the movement of the shell 2205 drives the connecting rod 2210 to move, the movement of the connecting rod 2210 drives the support plate 2211 to move, the movement of the support plate 2211 drives the smear rod 2218 to move, each group of smear rods 2218 will continue to move when it contacts a punching needle 2107, the two smear rods 2218 in each group will be blocked by the punching needle 2107 and move in opposite directions, the movement of the smear rod 2218 drives the positioning block 2219 to move, the movement of the positioning block 2219 The first elastic sheet 2221 is squeezed, and through the elastic property of the first elastic sheet 2221, the smear rod 2218 will fit with the punching needle 2107 when passing through the punching needle 2107, so that the liquid lubricant can be applied to the surface of the punching needle 2107. When the gear 2203 passes through the first tooth plate 2223, the housing 2205 will move from one side in front of the movable block 2108 to the other side in front. Then, when the gear 2203 is meshed with the second tooth plate 2223, the smear rod 2218 will move to the initial position in the above-mentioned moving state. When the movable block 2108 moves to the position in contact with the blocking rod 2110, it will continue to rise, and the blocking rod 2110 will squeeze the movable block 2108 to keep the movable block 2108 motionless.When the installation mold 2103 moves, it will drive the limit block 2109 to contact with the movable block 2108. Since the top of the limit block 2109 is set as an inclined surface, the limit block 2109 will be squeezed and moved. When the inner wall of the installation mold 2103 is completely moved to the position in contact with the movable block 2108, the limit block 2109 will be reset by the reaction force of the first spring 2111, so that the limit block 2109 enters the inner cavity of the movable block 2108, so that the movable block 2108 can be positioned so that the movable block 2108 will not move. Since the application rod 2218 has returned to the initial position and the bottom of the movable block 2108 is in contact with the inner wall of the installation mold 2103, the application rod 2218 will enter the movable block 2108 again. The inner cavity of the punching needle 2107, when passing through the mounting die 2103 again, will pass through the uniform coating ring 2201, and the uniform coating ring 2201 will evenly coat the liquid lubricating oil on the surface of the punching needle 2107. When the coating rod 2218 enters the inner cavity of the movable block 2108, the oil shell 305 will be squeezed out, and the movement of the oil shell 305 drives the extruder 303 to work. The operation of the extruder 303 transports the liquid lubricating oil inside the oil box 302 to the inner cavity of the oil shell 305 through the oil suction pipe 304, and then sprays it out from the nozzle 306. The amount of each spray is a small amount, which can meet the punching of the circuit board once. The sprayed liquid lubricating oil will soak the coating rod 2218 until the coating rod 2218 completely enters the movable block 2108. The inner cavity, when punching the next circuit board, the hydraulic cylinder on the punching machine body 11 moves the mounting frame 13 downward, the movement of the mounting frame 13 drives the mounting die 2103 to move, the movement of the mounting die 2103 drives the mounting rod 2222 to move, the movement of the mounting rod 2222 drives the fixing plate 2228 to move, the movement of the fixing plate 2228 drives the fixing shaft 2231 to move, the movement of the fixing shaft 2231 drives the extrusion plate 2229 to move, when the extrusion plate 2229 moves to the inclined surface at the top of the matching plate 2224, the matching plate 2224 is squeezed by the inclined surface at the top of the matching plate 2224, and the extrusion plate 2229 is prevented from rotating upward by the limiting position of the baffle plate 2230, and the matching plate 2224 is The movement drives the tooth plate 2223 to move, and the movement of the tooth plate 2223 drives the positioning rod 2225 to move, and at the same time squeezes the third elastic sheet 2227, so that the tooth plate 2223 moves to a position where it cannot mesh with the gear 2203. Since the length of the matching plate 2224 is longer than the length of the tooth plate 2223, after the squeezing plate 2229 is out of contact with the matching plate 2224, even if the tooth plate 2223 resets the gear 2203, it will not mesh with the tooth plate 2223. When the gear 2203 passes the second tooth plate 2223, it will also move according to the above principle, so that the gear 2203 will not mesh with the tooth plate 2223 during the downward movement. During the rising process of the gear 2203, the squeezing plate 2229 will be squeezed by the matching plate 2224 and rotate.The rotation of the extrusion plate 2229 squeezes the second elastic sheet 2232. When the extrusion plate 2229 is not in contact with the matching plate 2224, the reaction force of the second elastic sheet 2232 causes the extrusion plate 2229 to rotate to the initial state again. The elastic coefficient of the second elastic sheet 2232 is smaller than the elastic coefficient of the third elastic sheet 2227. Therefore, when the extrusion plate 2229 moves to the side of the matching plate 2224, the matching plate 2224 will not move. Then, the above steps are repeated to lubricate the punching needle 2107 during the punching of the circuit board. The operator does not need to manually apply lubricating oil to the surface of the punching needle 2107. At the same time, the lubrication effect between the punching needle 2107 and the circuit board can be ensured, and the punching effect and quality during punching can be ensured. At the same time, the punching needle 2107 can reduce the friction between the circuit board during the rising process, so that the circuit board and the punching needle 2107 can be better separated, thereby further ensuring the efficiency of punching.
