Description

Technical Field

[0001] This utility model relates to the field of PCB depaneling machines, and in particular to a cutting mechanism for a PCB depaneling machine. Background Technology

[0002] A sliding-blade PCB separator is a new type of machining equipment used for cutting electronic substrates such as PCBs with V-grooves and aluminum substrates. Its cutting structure mainly consists of a combination of an upper circular blade and a lower straight blade. The upper circular blade cuts the V-grooves horizontally to separate the boards. Conventional sliding-blade PCB separators require the operator to hold the PCB board on one side for support during cutting; this lack of support can lead to operator fatigue during prolonged operation. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a cutting mechanism for a PCB depaneling machine, which features an adjustable base plate for support, reducing fatigue.

[0004] The technical solution of this utility model is as follows:

[0005] A cutting mechanism for a PCB depaneling machine includes:

[0006] The tool feed mechanism includes a column, a translation mechanism, a housing, and an upper circular cutter. The column is respectively located on both sides of the machine base. The translation mechanism is mounted on the column. The housing is connected to the bottom of the translation mechanism. A first motor connected to the upper circular cutter is provided on the housing.

[0007] The lower blade, aligned with the cutting path of the upper circular blade, is positioned on the machine base;

[0008] The lifting seat includes a seat plate, a first lead screw, a guide post, and a connecting sleeve. The seat plate is located on one side of the lower cutting tool. The seat plate is provided with a first screw hole and a guide hole. The connecting sleeve is located on the machine base opposite the first screw hole. The bottom end of the first lead screw is rotatably connected to the connecting sleeve, and the top end passes through the first screw hole. The guide post is parallel to the first lead screw and is located on the machine base. The top end passes through the guide hole.

[0009] In a further technical solution, the housing is a flat housing with an open bottom, its long side being parallel to the upper circular blade, the upper circular blade being disposed inside the housing, and its bottom extending to the outer side of the bottom of the housing; the first motor is disposed on the outer wall opposite the long side of the housing, and the shaft of the first motor passes through the housing and connects to the upper circular blade.

[0010] In a further technical solution, the bottom of both sides of the wide side of the housing is provided with a stop block.

[0011] In a further technical solution, the side of the stop block facing the upward circular blade is arc-shaped to fit the contour of the upward circular blade, a dust suction chamber is provided inside the stop block, an opening communicating with the dust suction chamber is provided on one side of the arc-shaped edge of the stop block, and a dust suction connector for connecting a negative pressure dust collection device is provided on the side of the stop block away from the opening.

[0012] In a further technical solution, the translation mechanism includes a mounting shell, a second lead screw, a second motor, a connecting block, and a guide rail. The two ends of the mounting shell are respectively connected to the top of the column. The second motor is located inside one end of the mounting shell. After the second lead screw is connected to the second motor, its end is rotatably connected to the other end of the mounting shell. The middle of the connecting block has a second screw hole that engages with the second lead screw. The inner side of the mounting shell has a guide rail, and the connecting block is slidably connected to the guide rail. The bottom of the mounting shell has a strip-shaped opening, and the bottom of the connecting block extends through the strip-shaped opening and connects to the top of the casing.

[0013] In a further technical solution, the lower cutting tool includes a mounting plate and a lower straight blade. The mounting plate has vertically oriented oblong holes on both sides, and the lower straight blade has connecting holes aligned with the oblong holes. Bolts are inserted through the oblong holes and the connecting holes.

[0014] The beneficial effects of this utility model are:

[0015] 1. Before cutting, the height of the base plate can be adjusted by the first lead screw so that when the V-groove of the PCB board is aligned with the cutting tool, the top surface of the base plate is in contact with the bottom surface of the PCB board to provide support. When cutting PCB boards of the same specification, only the PCB board needs to be pressed down by hand for cutting, which reduces fatigue.

[0016] 2. The blocks on both sides of the machine casing can prevent accidental contact. The dust suction connector of the block can be connected to a negative pressure dust collection device to suck away the fine chips generated during cutting from the dust collection chamber.

[0017] 3. The lower straight cutter can be adjusted up and down along the oblong hole after the bolt is loosened to adjust the cutting gap and adapt to the V-groove depth of the PCB board. Attached Figure Description

[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0026] Example:

[0027] like Figures 1-4 As shown, a cutting mechanism for a PCB depaneling machine includes a base 10, a feed tool, a lower tool 30, and a lifting seat. The feed tool includes a column 21, a translation mechanism 22, a housing 23, and an upper circular blade 24 (a circular cutting blade). The column 21 is located on both sides of the base 10. The translation mechanism 22 is mounted on the column 21. The housing 23 is connected to the bottom of the translation mechanism 22. The housing 23 is driven by the translation mechanism 22 to slide horizontally for cutting. The translation mechanism 22 can be selected from the existing feed tool type PCB depaneling machine mechanism.

[0028] The housing 23 can be a flat housing with an open bottom, its long side being parallel to the upper circular blade 24. The upper circular blade 24 is located inside the housing 23, and its bottom extends to the outer side of the bottom of the housing 23. The first motor 25 is located on the outer wall opposite the long side of the housing 23, and the shaft of the first motor 25 passes through the housing 23 and connects to the upper circular blade 24. The lower blade 30 includes a mounting plate 31 and a lower straight blade 32 located on the mounting plate 31. The mounting plate 31 is located on the base 10, and the lower straight blade 32 is aligned with the cutting path of the upper circular blade 24.

[0029] The lifting base includes a base plate 41, a first lead screw 42, a guide post 43, and a connecting sleeve 44. The base plate 41 is located on one side of the lower cutter 30. A first screw hole is opened in the middle of the side of the base plate 41 away from the lower straight cutter 32, and guide holes are opened on both sides of the side closer to the lower straight cutter 32. The connecting sleeve 44 is located on the machine base 10 opposite to the bottom of the first screw hole. The bottom end of the first lead screw 42 is rotatably connected to the connecting sleeve 44, and the top end is set through the first screw hole. The guide post 43 is parallel to the first lead screw 42 and is set on the machine base 10, and the top end is set through the guide hole.

[0030] The working principle of the above technical solution is as follows:

[0031] Before cutting, the first lead screw 42 is rotated to adjust the height of the base plate 41 so that when the V-groove of the PCB board is aligned with the lower straight blade 32, the top surface of the base plate 41 is in contact with the bottom surface of the PCB board for support. At this time, the PCB board can be pressed down to be close to the base plate 41, and the translation mechanism 22 and the first motor 25 are started. The first motor 25 drives the upper circular blade 24 to rotate, and the translation mechanism 22 drives the upper circular blade 24 to slide horizontally, cutting the PCB board through the V-groove. This mechanism can be adapted to support different PCB boards, and compared with using the PCB board as support for cutting, it is less tiring.

[0032] In another embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the bottom of both sides of the wide side of the housing 23 is provided with a stop block 26; the side of the stop block 26 facing the upper circular blade 24 is arc-shaped to fit the contour of the upper circular blade 24, and there is a gap between this side and the upper circular blade 24; a dust suction chamber 261 is opened in the stop block 26, and an opening communicating with the dust suction chamber 261 is provided on one side of the arc-shaped side of the stop block 26, and a dust suction connector 262 for connecting a negative pressure dust suction device is provided on the side of the stop block 26 away from the opening.

[0033] The baffles 26 on both sides of the housing 23 can prevent accidental contact. The dust suction connector 262 of the baffle 26 can be connected to a negative pressure dust suction device to suck away the fine chips generated during cutting from the dust suction chamber 261.

[0034] In another embodiment, such as Figure 3 As shown, the translation mechanism 22 may include a mounting shell 221, a second lead screw 222, a second motor 223, a connecting block 224, and a guide rail 225. The second motor 223 is a servo motor, which can be controlled by the existing control system of a sliding-blade type PCB separator. The two ends of the mounting shell 221 are respectively connected to the top of the column 21. The second motor 223 is located inside one end of the mounting shell 221. After the second lead screw 222 is connected to the second motor 223, its end is rotatably connected to the other end of the mounting shell 221. The middle of the connecting block 224 has a second screw hole that fits into the second lead screw 222. The top of the inner side of the mounting shell 221 is provided with a guide rail 225. The connecting block 224 is slidably connected to the guide rail 225. The bottom of the mounting shell 221 has a strip-shaped opening. The bottom of the connecting block 224 extends through the strip-shaped opening and connects to the top of the housing 23.

[0035] After the second motor 223 starts, it drives the second lead screw 222 to rotate. Guided by the guide rail 225, the connecting block 224 drives the upper circular knife 24 inside the machine housing 23 to move smoothly and accurately.

[0036] In another embodiment, such as Figure 4 As shown, the mounting plate 31 has vertically oriented oblong holes 311 on both sides, and the lower straight blade 32 has connecting holes aligned with the oblong holes 311. Bolts are inserted through the oblong holes 311 and the connecting holes.

[0037] The lower straight blade 32 can be adjusted up and down along the oblong hole 311 after the bolt is loosened to adjust the cutting gap, adapt to the V-groove depth of the PCB board, and facilitate the replacement of the lower straight blade 32.

[0038] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
