Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to an automatic feeding device for a circuit board drilling machine. Background Art

[0002] When using a circuit board drill to drill holes in a circuit board, you need to place a pad under the circuit board to prevent the drill bit from hitting the bottom and damaging the equipment. Cover the top of the circuit board with aluminum foil to assist in heat dissipation and suppress burrs on the top surface. In addition, you need to stick tape on both sides of the aluminum foil to fix it to the pad.

[0003] In this process, Figure 2 The backing plate 4 shown has several fixing holes 41 around it for fixing it on the workbench 31 of the circuit board drilling machine. However, the backing plate 4 plays a protective role at the bottom and is thick enough so that it does not need to be replaced frequently. The two ends of the upper end surface of the backing plate 4 have several positioning holes 42 respectively. The positioning holes 42 are used to position the circuit board. Figure 3 As shown, before drilling begins, an automatic pinning machine is used to drive pins 51 into each end of the plate 5. When drilling is ready, the pins 51 are inserted into the positioning holes 42 to position the plate 5. Therefore, during the loading phase of the drilling process, frequent manual operations are required, including: securing the pinned circuit board to the backing plate, covering the circuit board with aluminum foil, and applying tape partially to the sides of the aluminum foil and partially to the backing plate to secure the backing plate, circuit board, and aluminum foil. These operations must be performed manually before each batch of circuit boards is automatically drilled, requiring considerable manpower. Summary of the Invention

Then, the aluminum foil is placed flat on the circuit board inside the machine, and the tape part is adhered to the pad. Then, the tape is cut and the application assembly is removed.

[0039] Working method:

[0040] First, the pad 4 is fixed to the workbench 31 of the circuit board drilling machine through the fixing hole 41, and then the preparatory work is carried out: first, a new roll of aluminum foil 7 loaded by the first I-shaped wheel 6 is set on the rotating frame 222, and then one end of the rotating frame 222 is inserted into the circular hole opened on the supporting seat 223 through the ninth linear mechanism 22, and then the aluminum foil 7 is pulled out a certain distance and passed between the table 23 and the pressure roller 231; then new tape 9 loaded by the second I-shaped wheel 8 is set on the two rotating rollers 282 respectively, and then the screw 285 is screwed and tightened with the screw hole 283. At this time, one end face of the third circular plate 284 is tightly against one end face of the second I-shaped wheel 8, so that the second I-shaped wheel 8 is clamped between the second circular plate 281 and the third circular plate 284, and then the tape 9 is pulled out a certain distance and passed to the outside of one side of the support plate 269.

[0041] Next, the staff places each plate 5 on the conveying starting end of the conveyor belt conveyor 11 in sequence. For example, in this embodiment, the number of plate 5 is five, which are used for distribution on five pads 4.

[0042] Preferably, the moving range of the first linear mechanism 12 not only covers the part outside the workpiece area of ​​the circuit board drilling machine 3, but also extends a certain distance to one end. The moving range of the eighth linear mechanism 21 not only covers the part outside the workpiece area of ​​the circuit board drilling machine 3, but also extends a certain distance to the other end. Therefore, the components on it can be moved to one end first by the eighth linear mechanism 21, that is, as shown in the attached figure. Figure 1 The end near the lower right corner shown in the figure avoids blocking the operation of the plate loading unit 1.

[0043] Then, the plate 5 is loaded into the circuit board drilling machine 3 through the plate loading unit 1. Take the first plate 5 as an example, and the following ones are similar: first, the sliding end is moved by the first linear mechanism 12 so that it is located at the position corresponding to the outer end of the pad 4 in the circuit board drilling machine 3. First, the output shaft of the fifth linear mechanism 152 is raised, so that the plate 5 can pass under the L-shaped plate 154 under the transportation of the conveyor belt 11. If the plate 5 is offset or deflected, the guide plate 156 can be used to guide the plate 5. At the same time, after the plate 5 reaches the area between the two guide plates 156, it can be pushed down by the fifth linear mechanism 152, and then the fourth linear mechanism 15 is used to control the long side direction of the L-shaped plate 154 close to the C-shaped plate 155, further guiding Toward, and clamp and lift the plate 5; then, the plate 5 is lifted by the third linear mechanism 14, and then the plate 5 is pushed into the circuit board drilling machine 3 by the second linear mechanism 13, and then the plate 5 is in the assembly position, that is, when the pin 51 is located above the positioning hole 42, the plate 5 is lowered again. When the plate 5 is about to approach the pad 4, each vacuum pump 132 is started, and air is extracted through the suction cup 191, and the suction cup 191 is lowered through the seventh linear mechanism 17 to make it contact the plate 5, and then the L-shaped plate 154 is pushed away by the fourth linear mechanism 15 and at the same time the support plate 163 is pushed away by the sixth linear mechanism 16 so that the lower end of the plate 5 is unobstructed, and then the plate 5 is lowered by the seventh linear mechanism 17, the pin 51 falls into the positioning hole 42, and the plate 5 is fixed on the pad 4.

[0044] After each plate 5 is loaded, the components thereon can be moved to the other end by the first linear mechanism 12, that is, as shown in the attached Figure 1 The end close to the upper left corner shown in the figure avoids blocking the operation of the auxiliary part loading unit 2.

[0045] Then, the aluminum foil 7 and the tape 9 are loaded onto the plates 5 in the circuit board drilling machine 3 through the auxiliary loading unit 2. Taking the first set of aluminum foil 7 and tape 9 as an example, the following are analogous: first, the bottom plate 211 is moved by the eighth linear mechanism 21 to a position corresponding to the outer end of a plate 5 in the circuit board drilling machine 3, and then the air clamp 251 is controlled by the twelfth linear mechanism 25 to drag the aluminum foil 7 on the table 23 from the side so that the length after cutting is greater than or equal to the length of the plate 5, and then the aluminum foil 7 is cut by the tenth linear mechanism 25. The linear mechanism 232 raises the receiving plate 234 so that its upper end surface is flush with the upper end surface of the table 23. Then, the eleventh linear mechanism 24 uses the first cutter 241 to cut the aluminum foil 7 into a rectangular piece. Then, the receiving plate 234 is lowered, and the air clamp 251 is moved back to a position close to the pressing roller 231. Next, the second rotary motor 28 rotates the second spool 8 to make the tape 9 fall until it just touches the rectangular aluminum foil. Then, the first rotary motor 264 rotates the rotating plate 265. At this time, The adhesive tape 9 will gradually be lowered, and a part of the adhesive tape 9 will be attached to the side of the aluminum foil 7. The rotating plate 265 will rotate until the position where the adhesive tape 9 is attached to the aluminum foil 7 is close to one end of the rectangle. Then, the rotating plate 265 will be rotated again by the first rotating motor 264. At this time, the adhesive tape 9 on the side of the aluminum foil 7 will also lift the rectangular aluminum foil 7. Next, the aluminum foil 7 and the adhesive tape 9 will be sent as a whole to the upper part of the inner end of the plate 5 in the circuit board drilling machine 3 by the thirteenth linear mechanism 26, so that the aluminum foil 7 can cover the inner end of the plate 5 in the circuit board drilling machine 3. The plate 5 is then rotated by the second rotary motor 28 to make the tape 9 fall a short distance so that it contacts the pad 4, and then the aluminum foil 7 and the tape 9 are rotated down as a whole by the first rotary motor 264. At this time, the originally idle part of the adhesive surface of the tape 9 can be pasted on the pad 4. After the aluminum foil 7 is covered on the plate 5, the tape 9 is cut by the second cutter 271 through the fourteenth linear mechanism 27. At this time, the adhesive effect of the tape 9 and the abutment of the support plate 269 can make the tape 9 taut during cutting, which is convenient for cutting.

[0046] The above are only some of the embodiments listed in this application and are not intended to limit this application.
