[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] To address the problems existing in the prior art, this embodiment provides the following technical solution: a printed circuit board contact cutting device, comprising an operating table 1 and a protective box 2. The protective box 2 is installed on the upper end of the operating table 1, and the interior of the protective box 2 is a cavity. A clamping and limiting mechanism 3 is provided on the lower front side of the interior of the protective box 2. The clamping and limiting mechanism 3 can clamp and fix circuit boards of different sizes, which facilitates the improvement of the accuracy of subsequent cutting of contacts on the circuit board. At the same time, a waste residue treatment mechanism 6 is provided. The waste residue treatment mechanism 6 is located on the upper and outer sides of the clamping and limiting mechanism 3, which can assist in cleaning the contact residue remaining on the upper side after the circuit board contact cutting is completed.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, a protective box 2 is installed on the upper part of the operating table 1. A rotating door is provided on the front side of the protective box 2, and a cutting component 4 is provided on the rear side of the inside of the protective box 2. The protective box 2 is designed so that when the cutting component 4 cuts the circuit board contacts, the contacts will not scatter everywhere.

[0028] By setting a clamping and limiting mechanism 3 inside the front of the protective box 2, the clamping and limiting mechanism 3 is located on the upper side of the cavity opened inside the upper end of the operating table 1. The cavity is set to facilitate the handling of waste after the circuit board contact is cut. The clamping and limiting mechanism 3 can fix the position of the circuit board to be cut, thereby ensuring the accuracy of circuit board cutting.

[0029] The clamping and limiting mechanism 3 includes a support base plate 31, which is located on the front inside of the protective box 2. The circuit board whose contact foot needs to be cut can be placed on the upper middle part of the support base plate 31. At the same time, the output shaft of the motor body 5 is fixedly connected to the left and right sides of the middle outer side of the support base plate 31. The motor body 5 is installed on the left and right sides of the front outside of the protective box 2, that is, the support base plate 31 is limited and installed on the front inside of the protective box 2.

[0030] Meanwhile, clamping plates 32 are symmetrically slidably arranged on the left and right sides of the middle of the support base plate 31. The lower end of the clamping plate 32 is located in the groove opened in the middle of the support base plate 31. In addition, the outer ends of connecting rods 33 are rotatably connected to the left and right sides of the outer side of the clamping plate 32. The inner ends of the connecting rods 33 are rotatably connected to the upper and lower sides of the outer side of the rotating plate 34. The connecting rods 33 are centrally symmetrically arranged on the outer side of the rotating plate 34. Furthermore, the inner side of the middle of the rotating plate 34 is rotatably connected to the front and rear sides of the middle of the support base plate 31. A first electric push rod 35 is arranged at the lower end of the middle of the support base plate 31. The right end of the first electric push rod 35 is fixed to the lower right side of the support base plate 31. The output end of the first electric push rod 35 is fixedly connected to the lower left side of the clamping plate 32 arranged on the left side of the support base plate 31.

[0031] The first electric push rod 35 can be opened, and the output end of the first electric push rod 35 can pull the connected clamping plate 32 to move. The left end of the connecting rod 33 is connected to the outside of the clamping plate 32. The other end of the connecting rod 33 is rotatably connected to the lower end of the rotating plate 34, which is rotatably set on the outer side of the middle of the support base plate 31. That is, when the clamping plate 32 on the left side of the support base plate 31 moves, the connecting rod 33 connected to it will rotate, and the rotating plate 34 connected to the connecting rod 33 will also rotate. When the rotating plate 34 rotates, it will pull the connecting rod 33 connected to the upper right side to rotate together, and then the clamping plate 32 connected to the right end of the connecting rod 33 will also move.

[0032] The rotation of the rotating plate 34 can drive the clamping plates 32 set on the left and right sides of the upper side of the support base plate 31 to move synchronously. That is, the clamping plates 32 can slide inward and outward on the upper middle part of the support base plate 31. When the clamping plates 32 move inward, they can fit tightly with the left and right ends of the circuit board placed on the upper middle part of the support base plate 31, thereby limiting the circuit board. By moving the clamping plates 32 synchronously, the circuit board can be fixed and limited above the middle part of the support base plate 31.

[0033] like Figure 3 As shown, after the circuit board is positioned, the contacts on the circuit board can be effectively cut by the cutting component 4 set inside the rear of the protective box 2. The cutting component 4 is composed of a cutting blade, a motor, an electric push rod and an electromagnetic slide rail.

[0034] The cutting blade is installed on the output shaft of the motor. When the motor is started, it can drive the cutting blade to rotate. At the same time, the output end of the electric push rod is fixedly connected to the rear side of the motor. When the electric push rod is opened, it can push the motor and the cutting blade installed on the output shaft to move forward, so that the two can be moved to the upper side of the clamping and limiting mechanism 3.

[0035] Meanwhile, a slider is installed at the rear end of the electric push rod one. The slider is located inside the electromagnetic slide rail. The left and right sides of the rear end of the electromagnetic slide rail are slidably connected to the rear side of the inner side of the protective box 2. Secondly, an electric push rod two is installed at the upper middle part of the electromagnetic slide rail. The top of the electric push rod two is fixedly connected to the rear side of the inner side of the protective box 2 for limiting. When the electric push rod two is opened, its output end can push the connected electromagnetic slide rail to move up and down. That is, when the electromagnetic slide rail moves, it can drive the motor, electric push rod one and cutting blade set at its front side to move together. The height of the cutting blade can be adjusted so that it contacts the contact pin on the circuit board.

[0036] At this point, the motor can be turned on to make the cutting blade rotate and cut the contact pins. At the same time, the controller can make the slider installed at the rear end of the electric push rod move left and right inside the electromagnetic slide rail, so as to easily adjust the left and right movement of the cutting blade and make it easy for the cutting blade to cut the contact pins on the circuit board.

[0037] The connection between the cutting components 4 is existing technology, and its function is to facilitate the adjustment of the cutting blade to fully cut the contact feet;

[0038] like Figure 2 and Figure 3 As shown, after the contact pins are cut, the cutting component 4 can be moved back to its original position and return to the rear of the inner side of the protective box 2. The waste residue of the cut contact pins will remain on the upper side of the circuit board. If it is not cleaned, it will cause damage to the circuit board when the cut circuit boards are taken out and stacked later.

[0039] After the tentacles are cut, the circuit board is located on the upper part of the support base plate 31, above the cavity opened at the upper end of the operating table 1. A waste bin 7 is set below the cavity opened at the operating table 1. At the same time, the output shaft of the motor body 5 is fixedly connected to the left and right sides of the middle outer end of the support base plate 31. By opening the motor body 5, the support base plate 31 can be rotated. The motor body 5 is set to rotate in both directions with a rotation angle of 90°. The two motor bodies 5 can be synchronized through synchronous control technology, which can make the support base plate 31 rotate from the initial horizontal state to the vertical state. The support base plate 31 can rotate forward, and the circuit board will also rotate 90°. At this time, the large tentacles waste residue remaining on the circuit board will fall from the surface of the circuit board into the cavity opened inside the operating table 1 into the waste bin 7. The waste bin 7 can collect the large tentacles waste. The size of the cavity opened inside the operating table 1 is larger than the size of the support base plate 31, so it does not affect the rotation of the support base plate 31.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, a waste residue treatment mechanism 6 is provided on the upper side of the interior of the protective box 2. The waste residue treatment mechanism 6 is located a little distance in front of the middle upper side of the clamping and limiting mechanism 3, and the height of the waste residue treatment mechanism 6 will not affect the rotation of the support base plate 31.

[0041] After the large contact waste on the circuit board is collected in the waste bin 7, some small waste remains on the surface of the circuit board. The waste treatment mechanism 6 includes a suction port 61, which is set at equal intervals on the lower side of the support frame 62. The suction ports 61 are set at a slight angle, and the direction of their suction holes corresponds to the surface of the vertical circuit board. The upper left and right sides of the support frame 62 are equipped with second electric push rods 63. The top of the second electric push rods 63 is fixedly connected to the upper side of the inside of the protective box 2, which can limit the position of the support frame 62. At the same time, a telescopic hose 64 is installed above each set of suction ports 61. The telescopic hose 64 has telescopic characteristics. The upper end of the telescopic hose 64 is connected to a connecting pipe 65. The lower rear side of the middle of the connecting pipe 65 is fixedly connected to an air pump 66, model DQE1480-55.

[0042] The air pump 66 can be turned on, generating suction. This suction is transmitted to the inside of the telescopic hose 64 through the connecting pipe 65. The telescopic hose 64 then transmits the suction to the chip suction port 61, which can suck up small debris from the surface of the circuit board. At the same time, the second electric push rod 63 can be turned on. The two second electric push rods 63 are synchronized by a synchronous controller, so they can start synchronously. The output end of the second electric push rod 63 can push the connected support frame 62 to move up and down, which in turn moves the chip suction port 61. At this time, the telescopic hose 64 installed on the upper side of the chip suction port 61 will stretch and contract, allowing the chip suction port 61 to efficiently absorb the debris adhering to the surface of the circuit board along the vertical direction of the circuit board. The absorbed debris can be transmitted to the air pump 66 through the telescopic hose 64 and the connecting pipe 65. The air pump 66 then transmits the debris to the waste bin connected to the rear, thus enabling the unified collection of small debris.

[0043] After the circuit board contacts have been cut and the debris has been cleaned up, the circuit board can be removed.

[0044] The motor model mentioned above is Z4-180-21, and the electric linear actuator model is HB-DJ801.

[0045] The working principle of the printed circuit board contact cutting equipment is as follows: A clamping and limiting mechanism 3 is set on the front side inside the protective box 2. The circuit board to be cut is placed on the upper end of the support base plate 31 set in the clamping and limiting mechanism 3. Then, the circuit board can be limited by the clamping and limiting mechanism 3. After the circuit board is limited, the cutting component 4 set on the rear side inside the protective box 2 can be used to cut the contact of the circuit board. After the contact of the circuit board is cut, the large waste residue and small waste chips left after the contact of the circuit board are cut can be effectively processed by the motor body 5 set on the outside of the support base plate 31 and the waste residue treatment mechanism 6 set on the upper side of the clamping and limiting mechanism 3.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
