A second gear 864 is fixedly connected to the output shaft of the second motor 861, and a first gear 863 for meshing with the second gear 864 is fixedly connected to the third screw rod 85.

The bottom end of the sliding plate 51 is fixedly connected to a fixed shaft 561, and a rack rod 563 is slidably connected to the fixed shaft 561. A first spring 5 for resetting the rack rod 563 is sleeved on the fixed shaft 561. 62, a fixed gear 564 for meshing with the rack rod 563 is fixedly connected to the second sleeve 55, one end of the first screw rod 52 is spirally connected to the first sleeve 53 rotatably connected to the housing 2, one end of the first screw rod 52 is spirally connected to the first sleeve 53, the bottom end of the housing 2 is rotatably connected to a transmission rod 865, the transmission rod 865 and the second gear 864 are rotatably connected to a transmission belt 862, the top of the transmission rod 865 is fixedly connected to a second bevel gear 866, the first sleeve 53 is fixedly connected to the first bevel gear 54 for meshing with the second bevel gear 866, a blowing assembly 7 is provided inside the housing 2, the blowing assembly 7 is used to clean impurities on the surface of the fixing plate 81 and the circuit board;

[0038] See also Figure 2 、 Figure 5-Figure 8When the cutting of the circuit board fixed above the fixed plate 81 is completed, the second motor 861 is started to drive the third lead screw 85 to rotate through the first gear 863, the third sleeve 84 is driven by the third lead screw 85 to slide down to the inside of the shell 2, and the lower bottom plate 82 slides down together with the fixed plate 81 under the limiting action of the second spring 83; when the lower bottom plate 82 slides down to the position where the lower bottom plate 82 contacts the baffle 6, the lower bottom plate 82 cannot continue to slide, the second spring 83 is compressed, and the lower elastic butt joint rod 88 on the top of the lower bottom plate 82 gradually penetrates through the fixed plate 81 and is located above the fixed plate 81 as shown in FIG. 9, so that the lower elastic butt joint rod 88 contacts the circuit board instead of the upper end surface of the fixed plate 81 and lifts the circuit board, so that a gap is generated between the circuit board and the upper end surface of the fixed plate 81, facilitating subsequent cleaning. Figure 7

[0039] When the second motor 861 drives the fixed plate 81 to slide down, the second motor 861 drives the transmission rod 865 to rotate, the transmission rod 865 drives the first bevel gear 54 to rotate through the second bevel gear 866, the first bevel gear 54 drives the first sleeve 53 to rotate, the first lead screw 52 extends from the inside of the first sleeve 53 to drive the rack bar 563 to slide, and the sliding of the rack bar 563 has two states; under the elastic force of the first spring 562, the rack bar 563 drives the sliding plate 51 to slide, and when the sliding plate 51 slides to one side of the sliding groove 4 and cannot continue to slide; at this time, the rack bar 563 compresses the first spring 562 to make the rack bar 563 slide relative to the sliding plate 51, and the sliding of the rack bar 563 drives the fixed gear 564 to rotate, the fixed gear 564 drives the second sleeve 55 to rotate, so that the second lead screw 57 drives the upper bottom plate 591 to slide down, and at this time, the lower elastic butt joint rod 592 that slides down cooperates with the lower elastic butt joint rod 88 that rises to lift the circuit board on the lower bottom plate 82 from both sides of the lower bottom plate 82, so that the circuit board is completely separated from the lower bottom plate 82, and because the lower elastic butt joint rod 88 and the upper bottom plate 591 can be stretched and contracted, the clamping effect of the lower elastic butt joint rod 88 and the upper elastic butt joint rod 592 on the circuit board is flexible fixing.

[0040] As a further scheme of the present application, the blowing assembly 7 comprises a first motor 71 fixed in the shell 2, a rotating disc 75 fixedly connected to the output shaft of the first motor 71, a convex shaft 74 fixedly connected to one end of the rotating disc 75, a sliding sleeve rod 73 sleeved outside the convex shaft 74, a fixed frame 72 fixedly connected in the shell 2, the sliding sleeve rod 73 being slidably sleeved in the fixed frame 72, a rotating seat 78 rotatably connected to one end of the sliding sleeve rod 73, a dust removal fan 79 fixedly connected to the rotating seat 78, convex rods 77 fixedly connected to the upper and lower ends of the rotating seat 78, and butt blocks 76 corresponding to the convex rods 77 fixedly connected to the upper and lower ends of the fixed frame 72.

[0041] Referring to​ Figure 4 When the rotating base 78 slides downward, the convex rod 77 on the top of the rotating seat 78 will gradually contact the docking block 76 and drive the rotating seat 78 to rotate along the docking block 76. The same effect will be produced when the rotating seat 78 slides downward, so that the blowing direction of the dust removal fan 79 is deflected downward when it rises, and the blowing direction is deflected upward when it falls, so as to clean the upper and lower end surfaces of the circuit board. After the lower elastic docking rod 88 and the upper elastic docking rod 592 fix the circuit board, the wind force of the dust removal fan 79 is enhanced to continue blowing. Since the circuit board is cut and becomes multiple parts from a whole, direct strong blowing is likely to cause the problem of partial circuit boards being blown over. The circuit board is fastened by the lower elastic docking rod 88 and the upper elastic docking rod 592 , which can prevent the circuit board from being deflected due to the strong blowing of the dust removal fan 79 .

[0042] As a further solution of the present invention, a gusset plate 3 is embedded in the front end of the shell 2, a base frame 10 is fixedly connected to the inside of the shell 2, a collection frame 11 is slidably connected to the upper end of the base frame 10, and a waste plate 9 is fixedly connected to the inside of the shell 2, the lower end of which is connected to the upper opening of the collection frame 11, and the upper end of the waste plate 9 is in contact with the outer wall of the bottom end of the lower base plate 82;

[0043] See also Figure 1 、 Figure 3 The debris blown away by the dust removal fan 79 can enter the collection frame 11 along the waste plate 9. By removing the buckle plate 3 from the shell 2, the collection frame 11 can be taken out from the shell 2, and the debris collected in the collection frame 11 can be cleaned, thereby realizing centralized processing of the debris.

[0044] As a further solution of the present invention, the upper end of the lower elastic docking rod 88 and the lower end of the upper elastic docking rod 592 are respectively fixedly connected with a cushioning layer for buffering effect;

[0045] The cushion layer is provided to further reduce the pressure, so that the pressure exerted by the lower elastic docking rod 88 and the upper elastic docking rod 592 on the surface of the circuit board is reduced, thereby avoiding extrusion and deformation of the circuit board.

[0046] As a further embodiment of the present invention, a CNC gong machining method comprises the following steps:

[0047] Step 1: Read the drill belt data, click the "Import File" option in the CNC machine software, select the required drill belt data and import it;

[0048] Step 2: Drill the PIN positioning holes. Read the drilling position according to the data, set the drilling depth, insert the drill bit into the machine spindle tool holder according to the tool magazine number, and stick adhesive tape on the diagonal positioning holes. Finally, start the machine to drill the positioning holes.

[0049] Step 3: Put the board on and insert the positioning pins, put the board to be cut on the position of the positioning pins, drive the pins into the drilled positioning holes, and use a hammer to knock the pins to fix them;

[0050] Step 4: Read the data from the gong belt and enter the parameters of the required tool into the parameter table. The required tool parameters include: tool diameter, rotation speed, tool down speed, tool travel speed, tool retraction speed, tool compensation, and tool life. Add a code after the tool diameter of each tool in advance to facilitate the CNC gong machine software to identify it. After adding, preset this parameter table in the background of the CNC gong machine software. When importing the gong belt data, the CNC gong machine software will enable its own loaded identification code function, which can automatically identify and import the parameters of the required tool according to the code;

[0051] See Figure 11-12 It can be seen that the control computer 1 is installed with CNC milling machine software. Before reading the milling belt data, it is necessary to add a two-digit code after the tool diameter to make a parameter table. Taking the tool with a diameter of 1.5 as an example, it becomes 1.501 after adding, plus the decimal point, a total of five digits, not one digit more or less. The completed parameter table is preset in the background of the CNC milling machine software. The CNC milling machine software is equipped with an identification code function, which can automatically identify the added code. When importing data, it will identify and import the parameters of the required tool according to the code. The operator only needs to check the imported parameters with the parameters on the tool table. After confirmation, the machine can be turned on to produce the first piece, thus avoiding entering incorrect parameters.

[0052] Step 5: Make the first piece and self-check. Select the area to be processed in the drawing and start the gong plate. After the first piece is made, perform self-check.

[0053] Step 6: Mass production and random inspection. After the first piece is confirmed to be OK, mass production will begin. After the first board is completed, 1SET (1PCS) board will be sampled from each axis to check the first piece.

[0054] Among them, the tool diameter is 0.8mm~2.4mm;

[0055] Among them, the tool speed is 26krpm~42krpm;

[0056] Among them, the knife lowering speed is divided into pre-gong knife lowering speed and repairing gong knife lowering speed. The pre-gong knife lowering speed is 0.6m / min~0.9m / min, and the repairing gong knife lowering speed is 1.2~2.0m / min.

[0057] The row cutter speed is divided into pre-cutting row cutter speed and finishing cutting row cutter speed, the pre-cutting row cutter speed is 0.3-0.9 m / min, and the finishing cutting row cutter speed is 1.2-2.0 m / min;

[0058] The tool compensation is divided into pre-cutting compensation and finishing cutting compensation, the pre-cutting compensation is divided into round hole compensation, inner groove compensation and outer shape compensation, the round hole compensation in the pre-cutting compensation is 0.76-1.95 mm, the inner groove compensation is 0.88-2.48 mm, and the outer shape compensation is 0.9-2.94 mm;

[0059] The tool compensation is divided into pre-cutting compensation and finishing cutting compensation, the pre-cutting compensation is divided into round hole compensation, inner groove compensation and outer shape compensation, the round hole compensation in the pre-cutting compensation is 0.76-1.95 mm, the inner groove compensation is 0.88-2.48 mm, and the outer shape compensation is 0.9-2.94 mm;

[0060] The tool compensation is divided into pre-cutting compensation and finishing cutting compensation, the pre-cutting compensation is divided into round hole compensation, inner groove compensation and outer shape compensation, the round hole compensation in the pre-cutting compensation is 0.76-1.95 mm, the inner groove compensation is 0.88-2.48 mm, and the outer shape compensation is 0.9-2.94 mm;

[0061] The tool compensation is divided into pre-cutting compensation and finishing cutting compensation, the pre-cutting compensation is divided into round hole compensation, inner groove compensation and outer shape compensation, the round hole compensation in the pre-cutting compensation is 0.76-1.95 mm, the inner groove compensation is 0.88-2.48 mm, and the outer shape compensation is 0.9-2.94 mm;

[0062] Working principle: when the circuit board fixed above the fixed plate 81 is cut, the second motor 861 is started to drive the third lead screw 85 to rotate through the first gear 863, the third sleeve 84 is driven by the third lead screw 85 to slide down to the inside of the shell 2, the lower bottom plate 82 slides down together with the fixed plate 81 under the restriction of the second spring 83, when the lower bottom plate 82 slides down to the position contacting with the baffle 6, the lower bottom plate 82 cannot continue to slide and the second spring 83 is compressed, and the lower elastic butt joint rod 88 on the top of the lower bottom plate 82 gradually penetrates through the fixed plate 81 and is located above the fixed plate 81 like Figure 7As shown, the lower elastic docking rod 88 replaces the upper end surface of the fixing plate 81 to contact the circuit board and lift the circuit board, so that a gap is generated between the circuit board and the upper end surface of the fixing plate 81. While the second motor 861 drives the fixing plate 81 to slide down, the second motor 861 drives the transmission rod 865 to rotate, and the transmission rod 865 drives the first bevel gear 54 to rotate through the second bevel gear 866. The first bevel gear 54 drives the first sleeve 53 to rotate, so that the first screw rod 52 extends from the inside of the first sleeve 53 to push the rack rod 563 to slide. The sliding of the rack rod 563 has two states; due to the first spring 562 Under the action of elastic force, the rack rod 563 drives the sliding plate 51 to slide. When the sliding plate 51 slides to one side of the sliding groove 4 and cannot slide further, the rack rod 563 compresses the first spring 562, causing the rack rod 563 to slide relative to the sliding plate 51. At this time, the sliding of the rack rod 563 drives the fixed gear 564 to rotate, and the fixed gear 564 drives the second sleeve 55 to rotate, thereby pushing the upper base plate 591 downward to slide through the second screw rod 57. At this time, the descending upper elastic docking rod 592 cooperates with the ascending lower elastic docking rod 88 to lift the circuit board on the lower base plate 82 from the upper and lower sides of the lower base plate 82.

[0063] After the fixed plate 81 drives the circuit board to slide into the inside of the shell 2, the dust removal fan 79 is started to blow air on the surface of the circuit board to remove debris. At the same time, the first motor 71 is started to drive the turntable 75 to rotate, and the turntable 75 drives the sliding sleeve rod 73 to reciprocate on the first motor 71. When the sliding sleeve rod 73 slides upward, the protruding rod 77 at the top of the rotating seat 78 will gradually contact the docking block 76 and drive the rotating seat 78 to rotate along the docking block 76. The same effect will be produced when the rotating seat 78 slides downward, so that the blowing direction of the dust removal fan 79 is deflected downward when it rises, and the blowing direction is deflected upward when it descends, thereby cleaning the upper and lower end surfaces of the circuit board.
