Description

Technical Field

[0001] This application relates to the technical field of PCB depaneling machines, and in particular to a dust collection device for mass production PCB depaneling machines. Background Technology

[0002] A PCB depaneling machine is a device used to separate circuit boards, primarily by separating connected circuit boards into individual units. PCB depaneling machines come in various types to suit different scenarios and requirements. Among them, milling cutter-type PCB depaneling machines are widely used for separating circuit boards requiring high precision and high strength because they can depanel boards of any shape, produce boards with low stress after depaneling, and have virtually burr-free cutting edges.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Traditional high-precision PCB depaneling machines generate a large amount of dust and debris during operation. Although a dust suction head is installed on the cutter holder to absorb the dust and debris, it is impossible to install the dust suction head around the circumference of the cutter due to the need to avoid the working space of the cutter. This means that only a portion of the dust and debris can be absorbed, and some dust and debris will still accumulate inside the PCB depaneling machine and disperse into the surrounding air as the PCB depaneling process proceeds. The PCB depaneling machine itself is easily affected by dust, leading to accelerated wear of parts. At the same time, the operators of the PCB depaneling machine are also prone to health threats due to excessive inhalation of dust. Utility Model Content

[0004] To address the problem that the dust collection head of traditional milling cutter-type PCB separators can only collect a portion of the dust generated during PCB separation, this application provides a dust collection device for mass-produced PCB separators.

[0005] The dust collection device for a mass production depaneling machine provided in this application adopts the following technical solution:

[0006] A dust collection device for a mass production depaneling machine includes:

[0007] The mounting base is located on the spindle seat of the PCB separator, and a dust suction hole is opened through it. The tool holder of the PCB separator passes through the dust suction hole. One end of the dust suction hole is sealed with the spindle seat of the PCB separator, and the other end of the dust suction hole is used for dust suction.

[0008] A suction pipe is located on the side wall of the mounting base and communicates with the suction hole, with one end connected to a vacuum cleaner.

[0009] A blocking mechanism is provided on the side wall of the mounting base at the dust suction end of the dust suction hole, which is used to isolate the milling space of the milling cutter and the dust suction hole from the outside world when the milling cutter is separating the plates.

[0010] The above technical solution isolates the working space of the milling cutter from the outside world. Then, the dust is sucked away along the dust suction hole through the dust suction pipe, making it difficult for the dust to drift to the outside world. Since the dust suction hole sucks up the entire working area of ​​the milling cutter, the dust generated by the milling cutter is absorbed relatively cleanly. At the same time, it makes it less likely for operators to suffer health damage due to excessive inhalation of dust.

[0011] Optionally, the blocking mechanism includes:

[0012] A mounting bracket is provided on the side wall of the mounting base and is sealed to the mounting base, through which one end of the milling cutter passes;

[0013] The bristles, arranged in a circular pattern, surround the suction end of the suction hole, and are used to isolate the milling space of the milling cutter and the suction hole from the outside world when the milling cutter is separating the plates.

[0014] Optionally, the mounting bracket is provided with a support, one end of which extends into the dust suction hole, and the end of the support located in the dust suction hole is provided with a guide hole through which a milling cutter passes. The guide hole is used to cooperate with the milling cutter to guide the mounting base during installation.

[0015] Optionally, the inner wall of the suction hole is provided with a plurality of suction ports spaced apart circumferentially, the suction ports being close to the suction end of the suction hole, and the mounting base is provided with a plurality of suction channels corresponding to the suction ports one by one, one end of each suction channel being connected to the suction pipe.

[0016] Optionally, all the suction ports are inclined toward the suction end of the suction hole.

[0017] Optionally, the mounting base has a plurality of connecting pipes on its side wall, one end of each connecting pipe being connected to a corresponding dust suction channel, and the other end of each connecting pipe being inserted into the dust suction pipe.

[0018] Optionally, the mounting base has a mounting block on its side wall, the mounting block has a connection hole, the end of the vacuum cleaner pipe away from the vacuum cleaner has a connector, one end of the connector is closed, the closed end of the connector has a plurality of insertion holes, the connecting pipe passes through the insertion holes one by one, and the connecting pipe has a fixing component for fixing the connector.

[0019] Optionally, a sliding hole is provided on one side wall of the connecting pipe, and the fixing assembly includes:

[0020] A fixing block is slidably installed in a sliding hole, with one end located inside the connecting pipe and the side facing the inside of the connecting pipe being inclined. It is used to slide out of the sliding hole and lock the inner wall of the connector end face when the airflow pushes the connecting pipe through.

[0021] Optionally, the fixing block is located at the end of the connecting pipe and on the upper side of the connecting pipe.

[0022] Optionally, the outer wall of the connector is provided with a rubber sealing layer.

[0023] In summary, this application has the effect of isolating the working space of the milling cutter from the outside world when the milling cutter is working, and then sucking away the dust along the suction hole through the dust suction pipe, so that the dust is not easy to drift to the outside world. Since the dust suction hole sucks the dust of the entire working area of ​​the milling cutter, the dust generated by the milling cutter is absorbed more cleanly. At the same time, it also makes it less likely for the operator to suffer health damage due to excessive inhalation of dust. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 —6 provides further details regarding this application.

[0033] The PCB separator in this embodiment is a milling cutter type PCB separator.

[0034] This application discloses a dust collection device for a mass production depaneling machine, referring to... Figure 1 , Figure 2 and Figure 3 It includes a mounting base 1 that is bolted to the bottom of the spindle seat of the PCB splitter, a dust suction pipe 2 located on the side wall of the mounting base 1, and a blocking mechanism 3.

[0035] Reference Figure 3 and Figure 5 The mounting base 1 has a dust suction hole 11 through it. The upper end of the dust suction hole 11 is sealed to the bottom wall of the spindle seat. The tool holder and the milling cutter coaxially pass through the dust suction hole 11.

[0036] Reference Figure 3 and Figure 5 The suction pipe 2 is connected to the suction hole 11, and the other end of the suction pipe 2 is connected to the vacuum cleaner. The dust generated by the milling cutter during plate separation is sucked away by the suction hole 11 and then enters the vacuum cleaner along the suction pipe 2.

[0037] Reference Figure 3 and Figure 5 The blocking mechanism 3 includes a ring-shaped mounting bracket 31 and bristles 32 fixedly arranged along the mounting bracket 31. The milling cutter coaxially passes through the mounting bracket 31, and the bristles 32 surround the milling cutter. When the milling cutter is split, the bristles 32 isolate the milling space of the milling cutter and the dust suction hole 11 from the outside, making it difficult for dust to be dispersed into the air during milling. The side wall of the mounting base 1 is provided with an air inlet 14 for air intake into the dust suction hole 11 to prevent the air pressure in the milling space of the milling cutter and the dust suction hole 11 from being too low.

[0038] Reference Figure 3 and Figure 4 A bracket 4 is fixedly installed on the mounting bracket 31 by bolts. One end of the bracket 4 extends into the dust suction hole 11, and the other end of the bracket 4 located in the dust suction hole 11 is provided with a guide hole 41 for passing through the milling cutter. When installing the mounting base 1, the mounting base 1 is guided by the cooperation between the milling cutter and the guide hole 41, making the installation of the mounting base 1 more convenient.

[0039] Reference Figure 3 and Figure 5 The inner wall of the suction hole 11 is provided with four suction ports 12 around its suction end. The suction ports 12 are inclined toward the suction end of the suction hole 11. Four suction channels 13 are provided in the mounting base 1. One end of the suction channel 13 is connected to the four suction ports 12 in a corresponding manner. The other end of the suction channel 13 extends to the same side wall of the mounting base 1.

[0040] Reference Figure 3 and Figure 5Four connecting pipes 5 are threaded onto the side wall of the mounting base 1. The connecting pipes 5 are square tubes. A rectangular mounting block 6 is fixed to the side wall of the mounting base 1 by bolts. A connecting hole 61 is opened through the middle of the mounting block 6, and all four connecting pipes 5 pass through the connecting hole 61.

[0041] Reference Figure 3 and Figure 6 A connector 7 is fixedly installed on one end of the vacuum tube 2. A rubber sealing layer 72 is fixedly provided on the outer wall of the connector 7. One end of the connector 7 is closed. Four insertion holes 71 are provided on the closed surface of the connector 7. The connector 7 is inserted into the connection hole 61, and the four connecting tubes 5 pass through the four insertion holes 71 respectively and are located inside the vacuum tube 2.

[0042] When the milling cutter is separating the plates, the vacuum cleaner starts to suck up dust through the four suction ports 12. Since the suction ports 12 are arranged around the milling cutter, the dust around the milling cutter can be sucked away, and the dust is not easy to accumulate at the milling cutter separation point. At the same time, since the end of the connector 7 is closed, the dust that may exist in the suction pipe 2 will not leak out from the suction pipe 2 when the suction pipe 2 is disassembled.

[0043] Reference Figure 5 and Figure 6 A sliding hole 51 is provided on the upper side of the end side wall of the connecting pipe 5. The connecting pipe 5 is provided with a fixing component 8. The fixing component 8 includes a fixing plate that is slidably installed in the sliding hole 51. The upper end of the sliding hole 51 is countersunk. Under normal conditions, the upper end of the fixing plate is fitted into the sliding hole 51.

[0044] Reference Figure 5 and Figure 6 The end of the fixing plate facing the inside of the connecting pipe 5 is beveled. When the connector 7 is inserted into the connecting hole 61, the vacuum cleaner is started, and the fixing plate slides upward under the push of the airflow. After the connector 7 is pressed tightly, the fixing plate can slide out of the sliding hole 51. After the connector 7 is released, under the action of the rubber sealing layer 72, the fixing plate presses against the end face of the connector 7 to fix the connector 7 to the mounting block 6. When disassembly is required, the connector 7 is pressed tightly again, and under the action of gravity, the fixing plate slides back into the sliding hole 51, and then the connector 7 can be pulled out from the connecting hole 61.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
