DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

A punching machine for circuit board production comprises: a workbench 1;

[0030] A support plate 2, wherein the support plate 2 is fixedly mounted on the top of the workbench 1;

[0031] The fixing frame 3 is fixedly installed on the front side of the supporting plate 2, an electric telescopic rod 31 is fixedly installed on the top of the fixing frame 3, a moving plate 32 is fixedly installed on the moving end of the electric telescopic rod 31, and side plates 33 are fixedly installed on both ends of the bottom of the moving plate 32, the bottom of the side plate 33 passes through the bottom of the inner side of the fixing frame 3 and extends to the bottom, a limiting groove 34 is arranged inside the side plate 33, a sliding rod 35 is fixedly installed on the inner side of the limiting groove 34, a sliding block 37 is slidably connected to the outer side of the sliding rod 35, a spring 36 is also sleeved on the outer side of the sliding rod 35, a positioning plate 38 is fixedly installed on one side of the sliding block 37, a pressing plate 39 is slidably connected to the outer side of the positioning plate 38, a locking screw 30 is internally threadedly connected to one end of the top of the pressing plate 39, and the bottom of the locking screw 30 is arranged on the top of the positioning plate 38;

[0032] The punching assembly 5 is fixedly installed on the bottom of the fixing frame 3 .

[0033] The punching assembly 5 includes a telescopic member and a punch. When in use, the punch is driven downward by the telescopic member to punch holes in the circuit board.

[0034] A first slide groove 11 is provided on the top of the workbench 1, and a second slide groove 12 is also provided on the top of the workbench 1. One end of the inner side surface of the second slide groove 12 is rotatably connected to a threaded rod 13. One end of the threaded rod 13 passes through the other end of the inner side surface of the second slide groove 12 and extends to the front side of the workbench 1. A handle 15 is fixedly installed on one end of the threaded rod 13, and the outer side surface of the threaded rod 13 is threadedly connected to a limiting plate 14.

[0035] A limiting rod 4 is fixedly mounted on the bottom of the pressing plate 39 , and the bottom of the outer side surface of the limiting rod 4 is arranged on the inner side surface of the first sliding groove 11 .

[0036] The limiting plate 14 is disposed on a side close to the supporting plate 2 .

[0037] The spring 36 is disposed on the top of the slider 37 .

[0038] When the electric telescopic rod 31 is in use, it can drive the movable plate 32 to move up and down, thereby limiting the position of the circuit board;

[0039] After the pressing plate 39 is pressed on the top of the circuit board, the slider 37 can slide upward on the outer side of the slide bar 35 to squeeze the spring 36, thereby playing a buffering role to avoid excessive pressure and damage to the circuit board;

[0040] When punching circuit boards of different sizes, the user can first place the circuit board on the workbench 1, and then rotate the handle 15 so that the handle 15 drives the threaded rod 13 to rotate, so that the threaded rod 13 is threadedly connected inside the limit plate 14, and the limit plate 14 is moved on the top of the workbench 1, thereby limiting the back position of the circuit board, and then the user moves the position of the pressing plate 39. When adjusting the position of the pressing plate 39, the two limit rods 4 need to be moved to the two sides of the circuit board, thereby limiting the two sides of the circuit board. Since the top of the limit rod 4 and the fixed position of the pressing plate 39 are still a certain distance away from the end face of the pressing plate 39, the circuit board can be pressed and limited through the gap. In this way, when punching the same batch of circuit boards in the future, it is only necessary to place the back of the circuit board against the front of the limit plate 14, and make the two sides of the circuit board on one side of the two limit rods 4, thereby positioning the circuit board that needs to be punched.

[0041] The working principle of a punching machine for circuit board production provided by the utility model is as follows:

[0042] When in use, the user places the circuit board to be punched on the workbench 1, and makes the back of the circuit board on one side of the limit plate 14, and makes the two sides of the circuit board in the middle of the two limit rods 4, so as to limit the circuit board. Then the user starts the electric telescopic rod 31, so that the moving end of the electric telescopic rod 31 drives the moving plate 32 and the side plate 33 to move downward. When the side plate 33 moves downward, it drives the positioning plate 38 and the pressing plate 39 to move downward until the bottom of the pressing plate 39 is pressed on the top of the circuit board, and at the same time the slider 37 moves upward, so that the slider 37 slides on the outer side of the slide rod 35 and squeezes the spring 36, so as to play a certain buffering force.

[0043] When limiting the position of circuit boards of different sizes, the user can rotate the locking screw 30 so that the locking screw 30 is threadedly connected inside the top of the pressure plate 39, and then move the bottom of the locking screw 30 away from the top of the positioning plate 38, so that the position of the pressure plate 39 can be adjusted to meet the use of circuit boards of different sizes.

[0044] Compared with the related art, the punching machine for circuit board production provided by the utility model has the following advantages:

[0045] Beneficial effects:

[0046] Through the cooperation of structures such as the side plate 33, the limiting groove 34, the sliding rod 35, the spring 36, the slider 37, the positioning plate 38, the pressing plate 39 and the locking screw 30, when in use, the user slides the pressing plate 39 on the outer side of the positioning plate 38, so as to adjust the position of the pressing plate 39, so as to limit the circuit boards of different sizes, thereby increasing the adaptability of the equipment.

[0047] Second embodiment

[0048] Please refer to Figure 5 Based on the punching machine for circuit board production provided in the first embodiment of the present application, the second embodiment of the present application proposes another punching machine for circuit board production. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0049] Specifically, the second embodiment of the present application provides a punching machine for circuit board production, which is different in that a punching machine for circuit board production has a limit frame 6 on the bottom of the side panel 33, and the interiors of both sides of the limit frame 6 are threadedly connected with mounting screws 61.

[0050] One end of the mounting screw 61 is disposed on a side surface of the side plate 33 .

[0051] The working principle of a punching machine for circuit board production provided by the utility model is as follows:

[0052] After long-term use, when the elasticity of the spring 36 decreases, the user can rotate the mounting screw 61 to move one end of the mounting screw 61 away from one side of the side plate 33, thereby moving the limit frame 6 downward and removing the limit frame 6 from the bottom of the side plate 33. Then, the user slides the slider 37 and the spring 36 down from the outer side of the slide rod 35 to replace the spring 36.

[0053] Compared with the related art, the punching machine for circuit board production provided by the utility model has the following advantages:

[0054] Beneficial effects:

[0055] By cooperating with each other through structures such as the limit frame 6 and the mounting screws 61, the limit frame 6 can be disassembled by rotating the mounting screws 61 during use, so that it is convenient for subsequent users to replace the spring 36 whose elasticity has decreased after long-term use.

[0056] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
