Description

Technical Field

[0001] This application relates to the field of PCB depaneling machine technology, specifically PCB depaneling machines. Background Technology

[0002] PCB, or Printed Circuit Board, is a carrier for the electrical connection of electronic components. A PCB depaneling machine is a device that performs professional segmentation of a complete PCB board.

[0003] An existing patent (publication number: CN222360248U) discloses a PCB board production and processing depaneling machine, relating to the field of depaneling machine technology. This application includes a base with a groove at one end of its top. Two transmission rollers are rotatably arranged on opposite sides of the inner wall of the groove, and a transmission belt is driven around the two transmission rollers. A bracket is located on the top of the base, and an electric push rod is mounted on the bracket. A movable frame is mounted on the piston end of the electric push rod, and a guide rod with its end sliding through the bracket is mounted on the movable frame. A rotating shaft is rotatably mounted on the movable frame, and the rotating shaft corresponds to one of the transmission rollers. In this application, the PCB board is placed on the transmission belt. The electric push rod performs work, causing the movable frame to move downwards, thereby pressing the PCB board on the transmission belt with a pressure cylinder. A drive mechanism drives the transmission rollers and the rotating shaft to rotate synchronously in opposite directions, so that the transmission belt and pressure cylinder can not only transport the PCB board but also clamp and fix it, ensuring the stability of the transport and the quality of the depaneling.

[0004] While the devices described in the aforementioned comparative documents can ensure the quality of cutting and separating the boards, they cannot conveniently collect the waste generated during the separation process. In order to further optimize the separation process, a PCB separation machine has been proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a PCB depaneling machine that can conveniently collect waste generated during the depaneling process and reliably remove the depaneled PCB boards, making it more practical.

[0006] To achieve the above objectives, this application provides the following technical solution: a PCB depaneling machine, comprising a base, a depaneling mechanism, and an auxiliary mechanism. The depaneling mechanism includes a processing chamber fixedly connected to the upper surface of the base and an electric slide rail fixedly connected to the bottom wall of the processing chamber. The inner wall of the electric slide rail is equipped with a depaneling groove. The auxiliary mechanism includes two inclined plates fixedly connected to the bottom wall of the processing chamber. The bottom wall of the processing chamber is equipped with two symmetrical material collection channels. A cavity is opened inside the base. The bottom of the two material collection channels are connected to the interior of the cavity. A material collection frame is placed on the inner wall of the cavity.

[0007] A conveyor belt and a pre-installed cover are installed at one end of the processing chamber. The pre-installed cover is located above the conveyor belt. A first cylinder is fixedly connected to the inner wall of the pre-installed cover. An installation plate is fixedly connected to the output end of the first cylinder. A second cylinder and an air pump are installed on the upper surface of the installation plate. A base plate is welded to the output end of the second cylinder. Multiple suction cups are installed on both sides of the bottom surface of the base plate. Two ventilation boxes are installed on the upper surface of the base plate. The multiple suction cups are respectively connected to the two ventilation boxes. A flexible air tube is connected to the top of each ventilation box. The tops of the two flexible air tubes are respectively installed on both sides of the air pump.

[0008] The above solution allows for stable cutting and separation of PCBs using a separate PCB separation mechanism. An auxiliary mechanism collects waste generated during the separation process and allows for the stable and rapid removal of multiple separated PCBs. Waste separated by the mechanism falls through two inclined plates into two collection channels, which then collect it into a collection frame. The suction cups, ventilation boxes, flexible air tubes, and air pump work together to lift the separated PCBs and transfer them to a conveyor belt, effectively optimizing the separation process.

[0009] Furthermore, baffles are fixedly connected to the two material collection channels on their opposite sides.

[0010] The above-mentioned solution can reduce the chance of waste splashing and optimize the waste collection effect.

[0011] Furthermore, four limiting rods are fixedly connected to the upper surface of the base plate, and all four limiting rods are slidably sleeved in the inner wall of the mounting plate.

[0012] The above solution allows the limiting rod to make the base plate more stable when moving up and down, which is beneficial for stable material handling and feeding.

[0013] Furthermore, a limiting block is fixedly connected to the inner top wall of the reserved cover, and two crossbars are fixedly connected to one side of the mounting plate. The two crossbars are slidably sleeved on the inner walls of the two limiting blocks, and a plug is fixedly connected to the same end of the two crossbars.

[0014] The above scheme allows the limiting blocks and crossbars to make the mounting plate more stable when it moves, and the plugs can limit the range of movement of the mounting plate, facilitating precise material handling.

[0015] Furthermore, a threaded rod is rotatably connected to the inner wall of the processing chamber, and a servo motor is fixedly connected to the outer surface of the processing chamber. The output shaft end of the servo motor is fixedly connected to the rotating shaft end of the threaded rod.

[0016] With the above solution, the servo motor can drive the threaded rod to rotate when it starts.

[0017] Furthermore, a U-shaped frame is threadedly connected to the outer surface of the threaded rod, a guide rod is fixedly connected to the inner wall of the processing chamber, the other side of the U-shaped frame is slidably sleeved on the outer surface of the guide rod, and two dividing plates are installed on the inner bottom wall of the U-shaped frame.

[0018] With the above solution, when the threaded rod rotates, the U-shaped frame can move along the guide rod inside the processing chamber, thereby enabling the PCB board placed on the partition slot to be cut and partitioned by the two partition plates.

[0019] Furthermore, a PLC controller and an operation panel are mounted on the upper surface of the base. The operation panel is electrically connected to the PLC controller, and the electrical components in the splitting mechanism and auxiliary mechanism are all electrically connected to the PLC controller.

[0020] The above scheme enables the PLC controller to easily achieve industrial automation control, optimizes the PCB separation process, and the operation panel allows staff to easily operate the device for PCB separation.

[0021] Furthermore, the inner wall of the cavity is equipped with a double door, and support columns are fixedly connected to the four corners of the base.

[0022] The above-mentioned design provides a certain degree of protection for the components inside the cavity and facilitates the regular cleaning of waste materials collected inside the collection frame. The support columns also allow the device to be placed more stably on the ground.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This PCB depaneling machine features a depaneling mechanism that allows for stable cutting and depaneling of PCBs. An auxiliary mechanism collects waste generated during the depaneling process and efficiently removes multiple depaneled PCBs quickly and stably. Waste falls through two inclined plates into two collection channels, ultimately being collected in a collection frame. Simultaneously, the device utilizes suction cups, ventilation boxes, flexible air hoses, and an air pump to lift and transfer the depaneled PCBs to a conveyor belt for rapid transport, optimizing the entire depaneling process and improving work efficiency.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figure 1 , Figure 2 and Figure 3The PCB depaneling machine in this embodiment includes a base 1, a depaneling mechanism 2, and an auxiliary mechanism 3. The depaneling mechanism 2 includes a processing chamber 201 fixedly connected to the upper surface of the base 1 and an electric slide rail 202 fixedly connected to the inner bottom wall of the processing chamber 201. A depaneling groove 203 is installed on the inner wall of the electric slide rail 202. A threaded rod 204 is rotatably connected to the inner wall of the processing chamber 201. A servo motor 205 is fixedly connected to the outer surface of the processing chamber 201. The output shaft end of the servo motor 205 is fixedly connected to the rotating shaft end of the threaded rod 204. When the servo motor 205 is started, it can... The threaded rod 204 is rotated. A U-shaped frame 207 is threadedly connected to the outer surface of the threaded rod 204. A guide rod 206 is fixedly connected to the inner wall of the processing chamber 201. The other side of the U-shaped frame 207 is slidably sleeved on the outer surface of the guide rod 206. Two partition plates 208 are installed on the inner bottom wall of the U-shaped frame 207. When the threaded rod 204 rotates, the U-shaped frame 207 can move along the guide rod 206 inside the processing chamber 201, so that the PCB board placed on the partition slot 203 can be cut and partitioned by the two partition plates 208.

[0035] Please see Figure 2 , Figure 3 and Figure 4 The auxiliary mechanism 3 includes two inclined plates 301 fixedly connected to the bottom wall of the processing chamber 201. Two symmetrical material collection channels 302 are installed on the bottom wall of the processing chamber 201. A cavity 303 is opened inside the base 1. The bottom of the two material collection channels 302 are connected to the inside of the cavity 303. A material collection frame 304 is placed on the inner wall of the cavity 303. A baffle 305 is fixedly connected to the side of the two material collection channels 302 that are far apart from each other. The baffle 305 can reduce the probability of waste splashing and optimize the waste collection effect. The waste generated during the process of separating the PCB board by the two separating plates 208 will fall into the two material collection channels 302 through the two inclined plates 301. The waste is then transported to the material collection frame 304 for centralized collection through the two material collection channels 302, which simplifies the waste collection process and makes it more practical.

[0036] Please see Figure 2 , Figure 5 and Figure 6A conveyor belt 306 and a pre-installed cover 307 are installed at one end of the processing chamber 201. The pre-installed cover 307 is located above the conveyor belt 306. A first cylinder 308 is fixedly connected to the inner wall of the pre-installed cover 307. A mounting plate 309 is fixedly connected to the output end of the first cylinder 308. When the first cylinder 308 is started, the horizontal position of the mounting plate 309 can be adjusted. A second cylinder 310 and an air pump 315 are installed on the upper surface of the mounting plate 309. A base plate 311 is welded to the output end of the second cylinder 310. When the second cylinder 310 is started, the vertical position of the base plate 311 can be adjusted. Multiple suction cups 312 are installed on both sides of the bottom surface of the base plate 311. Two ventilation boxes 313 are installed on the upper surface of the base plate 311. The multiple suction cups 312 are connected to the two ventilation boxes 313 respectively. The top of each ventilation box 313 is connected to a flexible air tube 314. The tops of the two flexible air tubes 314 are installed on both sides of the air pump 315. When the air pump 315 is started, the multiple suction cups 312 can be pumped through the two flexible air tubes 314 and the two ventilation boxes 313, so that multiple PCB boards that have been separated can be picked up by the multiple suction cups 312, which facilitates fast and stable material picking.

[0037] Please see Figure 2 , Figure 5 and Figure 6 Four limiting rods 316 are fixedly connected to the upper surface of the base plate 311. The four limiting rods 316 are slidably sleeved in the inner wall of the mounting plate 309. The limiting rods 316 make the base plate 311 more stable when moving up and down, which is beneficial to the stable material picking and unloading work. The inner top wall of the reserved cover 307 is fixedly connected to the limiting block 317. Two crossbars 318 are fixedly connected to one side of the mounting plate 309. The two crossbars 318 are slidably sleeved in the inner wall of the two limiting blocks 317 respectively. A plug 319 is fixedly connected to the same end of the two crossbars 318. The limiting block 317 and the crossbars 318 make the mounting plate 309 more stable when moving. The plug 319 can limit the range of movement of the mounting plate 309, which facilitates the precise material picking work.

[0038] Please see Figure 1 , Figure 2 and Figure 4The upper surface of the base 1 is equipped with a PLC controller 4 and an operation panel 5. The operation panel 5 is electrically connected to the PLC controller 4. The electrical components in the PCB separation mechanism 2 and the auxiliary mechanism 3 are all electrically connected to the PLC controller 4. The PLC controller 4 can easily achieve the effect of industrial automation control and optimize the PCB separation process. The operation panel 5 allows the operator to easily operate the device to perform PCB separation work. The inner wall of the cavity 303 is equipped with a double door 6. The four corners of the bottom surface of the base 1 are fixedly connected with support columns 7. The double door 6 can provide a certain degree of protection for the components inside the cavity 303, and also facilitates the periodic cleaning of the waste material collected inside the collection frame 304. The support columns 7 can make the device more stable to be placed on the ground.

[0039] In this embodiment, the PCB depaneling machine can stably cut and depanel PCBs through the depaneling mechanism 2, while the auxiliary mechanism 3 can collect the waste generated during the depaneling process. At the same time, it can stably and quickly remove multiple PCBs after depaneling. The waste cut by the depaneling mechanism 2 will fall into two collection channels 302 through two inclined plates 301, and then fall into the collection frame 304 for collection through the two collection channels 302. The suction cup 312, the ventilation box 313, the flexible air tube 314 and the air pump 315 work together to pick up multiple PCBs after depaneling and transfer them to the conveyor belt 306 for transportation, effectively optimizing the depaneling process.

[0040] The working principle of the above embodiment is as follows: The PCB board to be separated is placed on the separation slot 203. Then, the electric slide rail 202 is activated to move the separation slot 203 and the PCB board between the two inclined plates 301. Next, the servo motor 205 is activated. When the servo motor 205 is activated, it drives the threaded rod 204 to rotate. The rotation of the threaded rod 204 causes the U-shaped frame 207 to move along the guide rod 206. The movement of the U-shaped frame 207 towards the separation slot 203 allows the two separation plates 208 to separate the PCB board on the separation slot 203. When the U-shaped frame 207 moves to the entrance of the processing chamber 201, the servo motor 205 stops. Waste generated during the separation process falls through the two inclined plates 301 into the collection channel 302, and is then transferred to the collection frame 304 via the two collection channels, achieving convenient material collection. Then, the electric slide rail 202 is activated again to move the electric slide rail 205. The slide rail 202 moves the PCBs separated in the PCB separation slot 203 and the multiple PCBs separated on the PCB separation slot 203 to the outlet end of the processing chamber 201. At the same time, the first cylinder 308 is activated to move the mounting plate 309 above the PCB separation slot 203. Then, the second cylinder 310 is activated to move the base plate 311 down to a suitable position. Then, the air pump 315 is activated to pump air, so that multiple suction cups 312 can pick up the multiple PCBs below. Then, the second cylinder 310 moves the base plate 311 up to a suitable position, and the first cylinder 308 is activated to move the mounting plate 309 back to its original position. After the reset is completed, the second cylinder 310 can be activated to move the base plate 311 down, and the air pump 315 can be stopped. In this way, the multiple PCBs will fall onto the conveyor belt 306 and be transported out by the conveyor belt 306, thus completing the PCB separation work. After that, the above components can be reset to reuse the device for efficient PCB separation work.
