Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment technology, and in particular to an intelligent robotic arm for cutting electronic components. Background Technology

[0002] In the electronics manufacturing industry, PCB boards are the core carriers connecting various electronic components. As electronic products develop towards miniaturization and high density, the layout of components on PCB boards is becoming increasingly compact, which places extremely high demands on the precision and efficiency of PCB depaneling.

[0003] However, existing PCB shearing equipment still has problems in actual operation. First, in the positioning and clamping stage, traditional equipment uses an independent clamping mechanism to fix the PCB board on the worktable. However, the PCB board is prone to slight deformation due to temperature changes or its own weight during processing. The fixed clamping points cannot adaptively fit the board surface, resulting in the mechanical stress generated at the moment of shearing not being effectively released. This stress concentration can easily cause the micro-cracks on the edge of the PCB board to expand, and even cause breakage failure during subsequent use. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing an intelligent robotic arm for cutting electronic components.

[0005] The technical solution of the present invention: an intelligent robotic arm for cutting electronic components, including a robotic arm chassis and a robotic arm positioning component mounted on one side of the robotic arm chassis, and further including a mechanical positioning component mounted on one side of the robotic arm positioning component and a cutting component mounted on one side of the mechanical positioning component; The shearing assembly includes a first clamping block and a second clamping block. A second hydraulic telescopic frame is fixedly installed inside the first clamping block. A shearing block is fixedly installed at the output end of the second hydraulic telescopic frame. A telescopic rod is fixedly installed at the bottom of the second hydraulic telescopic frame. An upper flow divider and a lower flow divider are fixedly installed at the top of the second clamping block. The telescopic rod is slidably installed inside the upper flow divider. A second inclined insert is fixedly installed at one end of the telescopic rod extending into the second clamping block. Two sets of baffles are slidably installed between the lower flow divider and the upper flow divider. A fixing plate is fixedly installed on one side of the baffle. A first inclined insert is fixedly installed at the bottom of one set of fixing plates. The first inclined insert and the second inclined insert are slidably installed together. A multi-layer flow transfer frame is fixedly installed at the bottom of the lower flow divider.

[0006] Optionally, the robot positioning assembly includes a deflection positioning frame fixedly installed on one side of the robot chassis. The output end of the deflection positioning frame is fixedly installed with a robot main body plate. The robot main body plate is hinged to one side of the robot chassis. A first hydraulic telescopic frame is hinged to one side of the robot chassis. The robot main body plate is located on the outside of the first hydraulic telescopic frame.

[0007] Optionally, the robotic arm positioning assembly further includes a robotic arm extension hinged to the side of the robotic arm main plate away from the deflection positioning frame, and the output end of the first hydraulic telescopic frame is fixedly installed on the outside of the robotic arm extension.

[0008] Optionally, the mechanical positioning component includes a third motor fixedly installed at one end of the robot arm extension, a square frame fixedly installed at the output end of the third motor, and a second motor fixedly installed inside the square frame.

[0009] Optionally, a bidirectional positioning plate is fixedly installed at the output end of the second motor, a first motor is fixedly installed on the outer side of the bidirectional positioning plate, and two sets of second bidirectional hinge rods are rotatably installed inside the bidirectional positioning plate, with the output end of the first motor fixedly installed on the outer side of the second bidirectional hinge rods.

[0010] Optionally, the bidirectional positioning plate is internally hinged with two sets of first bidirectional hinge rods. One set of the first bidirectional hinge rods and the second bidirectional hinge rod are hinged to the outside of the first clamping block, and the other set of the first bidirectional hinge rods and the second bidirectional hinge rod are hinged to the outside of the second clamping block.

[0011] Optionally, limit brackets are fixedly installed on both sides of the bottom inner wall of the first clamping block, and an adaptive positioning clamp is slidably installed inside the limit bracket.

[0012] Optionally, a spring is fixedly installed between the adaptive positioning clamp and the limiting bracket, and the adaptive positioning clamp is in contact with both sides of the shearing block under normal conditions.

[0013] Optionally, there are two sets of fixing plates. Hollow racks are fixedly installed on the bottom of the multi-layer flow frame in both sets of fixing plates. The two sets of hollow racks are slidably installed inside the second clamping block. Two sets of auxiliary gears are rotatably installed on the inner wall of the second clamping block. The auxiliary gears are meshed with the hollow racks.

[0014] Optionally, an extended hollow block is fixedly installed at the bottom of the second inclined insert, the first inclined insert is slidably installed inside the extended hollow block, and a piston rod is fixedly installed on the outside of the extended hollow block, the piston rod being slidably installed inside the multi-layer flow rack.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. By pressing down the shearing block, the first and second inclined insert blocks cause the baffle plate to move inward synchronously. At the same time as shearing, the air passage area is automatically reduced to enhance the adsorption stability of the PCB board. After shearing, the air passage automatically switches to the blowing mode and the baffle plate moves outward to expand the blowing range. This can quickly dissipate heat from the high-temperature area of ​​shearing and provide separation thrust for the separated PCB board, thus realizing continuous automation of shearing and separation. 2. By using adaptive positioning clamps on both sides of the shearing block and being pushed outward by the oblique force of the blade during the shearing process, the spring force is overcome and the block moves outward along the limit bracket, so that its movement trajectory matches the separation trajectory of the PCB board after it is cut. This further releases the shearing stress and automatically scrapes off the residual debris on the blade during the reset process, ensuring the cutting accuracy of continuous operation. 3. The upper shunt plate uses negative pressure to adsorb the PCB board, forming a surface contact support. This allows it to adapt to the micro-deformation of the PCB board caused by temperature or its own weight, effectively releasing the mechanical stress during shearing, avoiding the generation and expansion of micro-cracks on the PCB board edge, and improving the yield rate.

[0018] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] like Figures 1 to 2 As shown, the present invention proposes an intelligent robotic arm for cutting electronic components, including a robotic arm chassis 1 and a robotic arm positioning assembly 2 mounted on one side of the robotic arm chassis 1, a mechanical positioning assembly 3 mounted on one side of the robotic arm positioning assembly 2, and a shearing assembly 4 mounted on one side of the mechanical positioning assembly 3. The robotic arm positioning assembly 2 includes a deflection positioning frame 202 fixedly mounted on one side of the robotic arm chassis 1, a robotic arm main body plate 201 fixedly mounted on the output end of the deflection positioning frame 202, the robotic arm main body plate 201 being hinged to one side of the robotic arm chassis 1, a first hydraulic telescopic frame 203 being hinged to one side of the robotic arm chassis 1, the robotic arm main body plate 201 being disposed on the outside of the first hydraulic telescopic frame 203, and the robotic arm positioning assembly 2 also includes a robotic arm extension 204 hinged to the side of the robotic arm main body plate 201 away from the deflection positioning frame 202, the output end of the first hydraulic telescopic frame 203 being fixedly mounted on the outside of the robotic arm extension 204.

[0024] In one implementation, for different electronic component installation positions, the fourth motor mounted on the deflection adjustment frame 202 drives the deflection adjustment frame 202 to deflect along the connection point with the robot chassis 1. During the deflection process, the deflection adjustment frame 202 uses the robot main plate 201 to drive the first hydraulic telescopic frame 203 to deflect synchronously. This causes the first hydraulic telescopic frame 203 to move the mechanical positioning component 3 and the shearing component 4 towards the position of the electronic component through the robot extension 204, so as to adapt to different installation angles of the PCB board. At the same time, the robot may be responsible for multiple production lines. If the PCB board is far away from the robot, the output end of the first hydraulic telescopic frame 203 extends and drives the robot extension 204 to deflect along the robot main plate 201. The robot extension 204 drives the mechanical positioning component 3 and the shearing component 4 to move to a more distant production line for processing, which improves the practicality of the robot.

[0025] like Figures 3 to 7As shown, in this embodiment, the mechanical positioning component 3 includes a third motor 307 fixedly installed at one end of the robot arm extension 204. A square frame 301 is fixedly installed at the output end of the third motor 307. A second motor 306 is fixedly installed inside the square frame 301. A bidirectional positioning plate 302 is fixedly installed at the output end of the second motor 306. A first motor 305 is fixedly installed on the outside of the bidirectional positioning plate 302. Two sets of second bidirectional hinge rods 304 are rotatably installed inside the bidirectional positioning plate 302. The output end of the first motor 305 is fixedly installed on the outside of the second bidirectional hinge rods 304. Two sets of first bidirectional hinge rods 303 are hinged inside the bidirectional positioning plate 302. One set of first bidirectional hinge rods 303 and second bidirectional hinge rods 304 are hinged to the outside of the first clamping block 401, and the other set of first bidirectional hinge rods 303 and second bidirectional hinge rods 304 are hinged to the outside of the second clamping block 402.

[0026] Furthermore, all motors in this application are reversible motors, and there are two first motors 305. One first motor 305 drives the first second bidirectional hinge rod 304 to deflect in the forward direction, while the other first motor 305 drives the second second bidirectional hinge rod 304 to rotate, causing the first clamping block 401 and the second clamping block 402 to move toward the surface of the PCB board. At the same time, a portion of the first clamping block 401 and the second clamping block 402 are respectively hinged by the first bidirectional hinge rod 303, which limits the first clamping block 401 and the second clamping block 402. During the deflection of the second bidirectional hinge rod 304 and the first motor 305, the first clamping block 401 and the second clamping block 402 will not deflect, but will move up and down, thereby ensuring that the first clamping block 401 and the second clamping block 402 will not be disturbed during the clamping of the PCB board, and improving the stability of the shearing assembly 4 in clamping and cutting operations.

[0027] like Figures 5 to 10 As shown, the shearing assembly 4 includes a first clamping block 401 and a second clamping block 402. A second hydraulic telescopic frame 403 is fixedly installed inside the first clamping block 401. A shearing block 414 is fixedly installed at the output end of the second hydraulic telescopic frame 403. A telescopic rod 404 is fixedly installed at the bottom of the second hydraulic telescopic frame 403. An upper diverter plate 405 and a lower diverter plate 406 are fixedly installed at the top of the second clamping block 402. The telescopic rod 404 is slidably installed inside the upper diverter plate 405. 04 A second inclined insert 416 is fixedly installed at one end extending into the second clamping block 402. Two sets of baffles 407 are slidably installed between the lower diverter plate 406 and the upper diverter plate 405. A fixing plate 408 is fixedly installed on one side of the baffle plate 407. A first inclined insert 415 is fixedly installed at the bottom of one set of fixing plates 408. The first inclined insert 415 and the second inclined insert 416 are slidably installed. A multi-layer flow frame 411 is fixedly installed at the bottom of the lower diverter plate 406.

[0028] It is worth noting that in the positioning and clamping stage, traditional equipment often uses an independent clamping mechanism to fix the PCB board on the worktable. Because the PCB board is prone to slight deformation due to temperature changes caused by hard contact with the cutting tool during the cutting process, the fixed clamping points cannot adaptively conform to the board surface, resulting in the ineffective release of mechanical stress generated during shearing. This stress concentration can easily cause the propagation of micro-cracks at the edges of the PCB board. In contrast, the device of this application first uses the mechanical positioning component 3 to move the first clamping block 401 and the second clamping block 402 towards the PCB board. At this time, the upper surface of the second clamping block 402 is in contact with the lower surface of the PCB board. The surface of the second clamping block 402 has a piezoelectric sensor, which detects the pressure signal and reacts accordingly. Feedback is sent to the central controller, which then instructs the air pump built into the multi-layer flow rack 411 to start the suction mode. At this time, due to the suction force of the air pump, the upper flow divider plate 405 and the PCB board are brought into close contact, and the contact area between the two is sealed. The upper flow divider plate 405 and the PCB board form a negative pressure adsorption, which initially adsorbs and fixes the PCB board. At the same time, the output end of the second hydraulic telescopic frame 403 drives the shearing block 414 to move towards the specified cutting position of the PCB board. The position of the second hydraulic telescopic frame 403 away from the cutting point drives the telescopic rod 404 to move downward. During the downward movement of the telescopic rod 404, since the telescopic rod 404 is telescopic, the friction between the second inclined insert 416 and the first inclined insert 415 is greater than the telescopic force. The thrust of the telescopic rod 404 during retraction keeps the second inclined insert 416 stationary. The telescopic rod 404 then retracts to its shortest state, with the distance between the shearing block 414 and the PCB board cutting point between 5cm and 8cm. As the second hydraulic telescopic frame 403 continues to move the telescopic rod 404, the telescopic rod 404 moves downwards along the upper diverter plate 405. The telescopic rod 404 drives the second inclined insert 416 at its end to slide down the slope of the first inclined insert 415. During this process, the second inclined insert 416 generates a horizontal component force on the first inclined insert 415. The first inclined insert 415 drives the baffle plate 407 to move along the lower diverter plate 406 towards the middle of the upper diverter plate 405. The inward movement of the baffle plate 407 causes the upper diverter plate 405 to intersect with the lower diverter plate 405. The reduced cross-sectional area of ​​the airflow channel between plates 406, according to fluid mechanics principles, leads to increased flow velocity and decreased static pressure when the air pump's suction power remains constant. This significantly enhances the adsorption force of the upper diverter plate 405 on the PCB board, ensuring the PCB board remains motionless under shearing impact. Simultaneously, the second inclined insert 416 drives the extended hollow block 413 and piston rod 412 downwards, compressing the gas within the multi-layer flow frame 411, further increasing the negative pressure value within the system and creating a dual pressure stabilization effect. As the shearing block 414 moves downwards to shear, the PCB board breaks. Due to the negative pressure adsorption method of fixation, compared to traditional clamping fixation, the PCB board is not damaged due to stress contact with the clamping components when it is cut.It can reduce the stress and impact generated during PCB board cutting. Meanwhile, the waste material falling from the middle of the cut PCB board is attracted by the upper diverter plate 405 and propelled away from the PCB board, improving the cutting quality. When the shearing block 414 moves upward away from the cutting range of the PCB board, the first inclined insert 415, under the pulling force of the second inclined insert 416, drives the baffle plate 407 outward through the fixed plate 408, causing the airflow area between the upper diverter plate 405 and the lower diverter plate 406 to increase. The central controller controls the air pump to instantly switch from suction mode to blowing mode. Simultaneously, the blowing range between the lower diverter plate 406 and the upper diverter plate 405 widens, meaning the airflow passing through the PCB board cutting point widens, providing thrust for the PCB board to separate, accelerating the separation and improving the separation efficiency after cutting. At the same time, the airflow is ejected at high speed through the expanded flow channel, rapidly dissipating heat from the PCB board cutting area and preventing deformation due to localized high heat after cutting.

[0029] In this configuration, a limit bracket 417 is fixedly installed on both sides of the bottom inner wall of the first clamping block 401. An adaptive positioning clip 418 is slidably installed inside the limit bracket 417. A spring is fixedly installed between the adaptive positioning clip 418 and the limit bracket 417. Under normal conditions, the adaptive positioning clip 418 is in contact with both sides of the shearing block 414. There are two sets of fixing plates 408. Hollow racks 409 are fixedly installed on both sets of fixing plates 408 at the bottom of the multi-layer flow frame 411. The two sets of hollow racks 409 are slidably installed inside the second clamping block 402. Two sets of auxiliary gears 410 are rotatably installed on the inner wall of the second clamping block 402. The auxiliary gears 410 are meshed with the hollow racks 409.

[0030] Furthermore, when the telescopic rod 404 moves a baffle 407 via the first inclined insert 415, the fixing plate 408 on one side of the first inclined insert 415 drives the hollow rack 409 to slide horizontally along the inner wall of the second clamping block 402. The auxiliary gear 410 rotates by meshing with the hollow rack 409. The other hollow rack 409 drives another baffle 407 to slide via another fixing plate 408. The two baffles 407 move in opposite directions. By utilizing the symmetrical change of the airflow flow area between the lower diverter plate 406 and the upper diverter plate 405, the stability of the PCB board affected by airflow changes is improved.

[0031] Simultaneously, when the shearing block 414 and the adaptive positioning clamp 418 come into contact with the PCB board, the adaptive positioning clamp 418, as the upper surface clamping component of the PCB board, generates a shearing motion as the shearing block 414 moves downward. Since the blade surface of the shearing block 414 is inclined, the adaptive positioning clamp 418 is pushed by the inclined blade surface of the shearing block 414, overcomes the elastic force of the spring, and moves outward along the limit bracket 417. The adaptive positioning clamp 418 generates an outward pushing force on the PCB board, and its movement trajectory matches the trajectory of the shearing block 414 shearing the PCB board, causing the PCB board to be divided into two pieces and move outward. This reduces the mechanical stress generated at the moment of shearing the PCB board, allowing the shearing plate of the PCB board to be released to a certain extent. At the same time, when the shearing block 414 is retracted, the shearing block 414 and the inner wall of the adaptive positioning clamp 418 come into relative contact, causing the residual material of the PCB board cut by the shearing block 414 to be scraped off, avoiding the shearing block 414 from being affected in subsequent cutting.

[0032] The above specific embodiments are merely several optional embodiments of the present invention.
