Description

Technical Field

[0001] This invention relates to the field of circuit board depaneling technology, and more specifically, to a fully automatic online depaneling and unloading system. Background Art

[0002] PCB (Printed Circuit Board), also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. To meet the needs of mass production, multiple PCBs are usually connected together during the manufacturing process. Therefore, in subsequent processing steps, these connected PCBs need to be separated.

[0003] A typical circuit board depaneling machine on the market has a structure similar to that shown in patent document CN202410783562.1, entitled "A Circuit Board Cutting Equipment." It includes a frame body and a feeding section and a cutting section mounted on the frame body. The frame body also has a tray-loading section. The feeding section includes a feeding structure and a picking structure for retrieving materials from the feeding structure. The cutting section includes a cutting mechanism and at least two sets of transport mechanisms and pressing mechanisms to transport circuit boards to the area below the cutting mechanism. The tray-loading section includes a handling mechanism and a tray-loading mechanism, which places each circuit board transported by the handling mechanism to the next workstation. However, the loading and unloading of this equipment is entirely performed by a single robotic arm, and the spacing between the workstations is large, resulting in a long movement time of the circuit boards between different workstations. There is significant room for improvement in the equipment's efficiency. Furthermore, the layout of the workstations is not optimal.

[0004] Therefore, it is necessary to research and upgrade the structure of automated circuit board depaneling machines. Summary of the Invention

[0005] To address the issues of long loading and unloading times, complex programming, large equipment size, and unreasonable structural layout in current circuit board depaneling machines on the market, we provide a fully automatic online depaneling and unloading system.

[0006] The fully automatic online plate sorting and unloading system includes a plate picking assembly, which includes a translational lifting arm. The translational lifting arm is equipped with a feeding suction cup and a discharging suction cup. Below the translational lifting arm, along the translational conveying direction, a plate feeding assembly, a cutting platform, and a discharge assembly are arranged in sequence. The feed plate assembly includes left and right symmetrical fixed guide rails and translation guide rails. The bottom of the translation guide rail is connected to a translation slide table. Both the fixed guide rail and the translation guide rail are equipped with push belts on their inner sides. A circuit board holder is detachably installed in the cutting platform, and a cutting robotic arm is installed above the cutting platform; The discharge assembly includes a discharge conveyor belt, which is installed on the front and rear slides along the translational conveying direction, and a waste recycling trough is provided below the discharge conveyor belt; The distance between the feeding assembly and the cutting platform, and the distance between the cutting platform and the discharge assembly are equal to the distance between the feeding suction cup and the unloading suction cup.

[0007] Furthermore, the loading suction cup, unloading suction cup, and translational lifting arm are respectively connected via lifting servo units.

[0008] Furthermore, both the loading suction cup and the unloading suction cup include a suction cup frame, and multiple vacuum suction cups are detachably installed on the inner side of the suction cup frame.

[0009] Furthermore, the cutting platform includes a reciprocating guide rail, a circuit board holder is detachably mounted on the reciprocating guide rail, and a board picking assembly and a cutting robotic arm are respectively disposed above both ends of the reciprocating guide rail.

[0010] Furthermore, a cutting mold is provided above the circuit board holder, and the cutting mold is detachably connected to the front end of the switch push rod.

[0011] Furthermore, the cutting robot arm includes a second translational lifting arm, on which a slitting cutter is mounted.

[0012] Furthermore, the board cutting blade is wrapped with a dust suction hood, and the bottom of the dust suction hood and the circuit board holder are both connected to an industrial dust collector through a dust suction hose.

[0013] Furthermore, one or more cutting platforms are arranged between the feeding assembly and the discharging assembly.

[0014] Furthermore, the plate picking assembly, plate feeding assembly, cutting platform, and discharge assembly are all installed in the equipment body and are electrically connected to the industrial control computer, which is located at the front end of the equipment body.

[0015] Furthermore, a protective door is provided on the outside of the equipment body, and a door closing sensor is provided on the inside of the protective door. The door closing sensor is electrically connected to the industrial control computer.

[0016] The advantages of this invention are: 1. The circuit board processing equipment is laid out in a straight line, which shortens the transfer time between the equipment stations, effectively reducing the time spent transporting circuit boards and improving equipment efficiency.

[0017] 2. The board picking and placing can be carried out simultaneously, the board picking assembly does not need to be moved frequently, and the equipment operates with low noise.

[0018] 3. The discharge conveyor belt is integrated with a switchable waste recycling trough, which allows for convenient selection of whether to activate the recycling trough as needed. The forward and backward movement design of the discharge conveyor belt can shorten the travel distance of the plate picking assembly.

[0019] 4. The cutter and circuit board holder are equipped with a unified dust collection system, and the entire equipment is isolated from the outside world. The equipment has little impact on the surrounding environment during operation, and the dust and waste generated during cutting can be properly recycled, making it highly environmentally friendly.

[0023] To address the issues of long loading and unloading times, complex programming, large equipment size, and unreasonable structural layout in current circuit board depaneling machines on the market, we provide a fully automatic online depaneling and unloading system.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that the terms such as “inner,” “middle,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as part of the scope of the invention, and this is hereby stated.

[0026] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0027] like Figures 1 to 6 As shown, this embodiment provides a fully automatic online plate sorting and unloading system, including a plate picking assembly 1. The plate picking assembly 1 includes a translational lifting arm 101, on which a feeding suction cup 102 and a discharging suction cup 103 are installed. Below the translational lifting arm 101, along the translational conveying direction, a plate feeding assembly 2, a cutting platform 3, and an unloading assembly 4 are arranged in sequence. The feed plate assembly 2 includes a fixed guide rail 201 and a sliding guide rail 202 that are symmetrical on the left and right sides. The bottom of the sliding guide rail 202 is connected to a sliding slide 203. A push belt 5 is provided on the inner side of both the fixed guide rail 201 and the sliding guide rail 202. A circuit board holder 301 is detachably installed in the cutting platform 3, and a cutting robot arm is provided above the cutting platform 3; The discharge assembly 4 includes a discharge conveyor belt 401, which is installed on the front and rear slides 402 along the translational conveying direction. A waste recycling trough 403 is provided below the discharge conveyor belt 401. The distance between the feeding assembly 2 and the cutting platform 3, and the distance between the cutting platform 3 and the discharging assembly 4 are both equal to the distance between the feeding suction cup 102 and the discharging suction cup 103.

[0028] The board feeding assembly 2 can adjust the distance between the fixed guide rail 201 and the sliding guide rail 202 according to the width of the circuit board, thereby quickly adapting to circuit boards of different specifications. Combined with the replaceable circuit board holder 301, it enables rapid setup of different production products. The movable discharge conveyor belt 401 allows the waste recycling tank 403 to be opened and closed as needed, avoiding the need for the sliding lifting arm 101 to cross the waste recycling tank 403 for unloading when it is not in use, thus reducing transportation time; it also prevents materials from accidentally falling into the waste recycling tank 403. Since the distance between the loading and unloading suction cups is equal to the distance between the two workstations, after the loading suction cup 102 aligns with one workstation, the unloading suction cup 103 will align with the next workstation, allowing the loading and unloading processes to run simultaneously.

[0029] The loading suction cup 102, unloading suction cup 103, and translational lifting arm 101 are respectively connected via a lifting servo 6. The loading suction cup 102 and unloading suction cup 103 can be lifted and lowered independently, resulting in high operating efficiency.

[0030] Both the loading suction cup 102 and the unloading suction cup 103 include a suction cup frame 11, and multiple vacuum suction cups 12 are detachably installed on the inner side of the suction cup frame 11. The loading suction cup 102 and the unloading suction cup 103 can also be configured with different suction cup styles according to the specifications of the circuit board, which facilitates quick adaptation to the production of different products.

[0031] The cutting platform 3 includes a reciprocating guide rail 302, and a circuit board holder 301 is detachably mounted on the reciprocating guide rail 302. The board picking assembly 1 and the cutting robotic arm are respectively located above both ends of the reciprocating guide rail 302. Since the cutting robotic arm is located at the other end, the cutting robotic arm can simultaneously perform board splitting and cutting when the board picking assembly 1 is running, and the various workstations will not interfere with each other, resulting in high work efficiency.

[0032] A cutting mold 303 is provided above the circuit board holder 301, and the cutting mold 303 is detachably connected to the front end of the switch push rod 304. The detachable and replaceable cutting mold 303 facilitates the adaptation to different circuit board specifications and avoids dust generated during board separation and cutting from splashing into the outside.

[0033] The cutting robotic arm includes a second translational lifting arm 305, on which a slitting cutter 306 is mounted. The second translational lifting arm 305 can use the same components as the translational lifting arm 101, which is highly versatile and facilitates the setting of the operating path and maintenance.

[0034] The PCB cutter 306 is encased in a dust collection hood 7. Both the dust collection hood 7 and the bottom of the circuit board holder 301 are connected to an industrial dust collector (not shown in the figure) via a suction hose 8. During PCB cutting, the dust collection hood 7 and the bottom of the circuit board holder 301 can simultaneously suction dust from above and below via the suction hose 8, effectively removing dust generated during PCB cutting, preventing dust contamination of the equipment, and keeping the circuit board surface clean.

[0035] One or more cutting platforms 3 are arranged between the feeding assembly 2 and the discharging assembly 4. Since plate cutting is generally time-consuming, the plate picking assembly 1 will have a long standby time after loading. In order to improve work efficiency, multiple cutting platforms 3 can be set up at the same time, and one plate picking assembly 1 can be used for loading and unloading.

[0036] The board picking assembly 1, board feeding assembly 2, cutting platform 3, and discharging assembly 4 are all installed in the equipment body 9 and electrically connected to the industrial control computer 10, which is located at the front end of the equipment body 9. The equipment body 9 isolates the board separating system from the external environment, preventing interference from the external environment during equipment operation. The industrial control computer 10 can be a commonly used product on the market (such as Nodajia NP-6116), which facilitates the management of the operating parameters of each workstation.

[0037] A protective door 901 is provided on the outer side of the equipment body 9, and a door closing sensor 902 is provided on the inner side of the protective door 901. The door closing sensor 902 is electrically connected to the industrial control computer 10. The door closing sensor 902 can be a commonly used proximity switch. The equipment can only start after detecting that the protective door 901 is closed, which ensures high safety.

[0038] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
