Description

Technical Field

[0001] This invention relates to the field of circuit board processing equipment technology, and specifically to a circuit board processing flipping machine. Background Technology

[0002] In the production and processing of circuit boards, flipping is required to perform double-sided processing (such as soldering, mounting, etching, etc.). As a key piece of equipment in the circuit board processing production line, the performance of the flipping machine directly affects the processing efficiency, accuracy, and product qualification rate.

[0003] Currently, existing circuit board flipping machines have several shortcomings. First, in the substrate conveying stage, most flipping machines use a single conveyor belt, lacking effective positioning and stabilization mechanisms. This causes the substrate to easily shift and shake during transport, affecting the accuracy of subsequent gripping and flipping. Especially for thin circuit boards, this can lead to substrate wrinkling and damage. Second, in terms of flipping mechanism design, some flipping machines use a simple cylinder-driven flipping structure, resulting in low precision in flipping angle control. They cannot achieve precise 180-degree flipping, and the substrate is prone to detachment and displacement during flipping, affecting processing quality. Third, existing flipping machines lack adequate safety protection measures and effective protective structures. During operation, operators are prone to collisions with moving parts, posing safety hazards. Furthermore, the equipment has poor adaptability, unable to be flexibly adjusted for different circuit board specifications, limiting its applicability. In addition, the overall structural design of existing flipping machines is unreasonable, with messy wiring. This not only affects the aesthetics of the equipment but also easily leads to wire wear, short circuits, and other malfunctions, reducing the equipment's operational stability and lifespan.

[0004] For example, Chinese utility model patent CN215620887U discloses a flipping device for circuit board processing, including a frame, a conveying mechanism, and a flipping mechanism. The conveying mechanism includes conveying rollers and a drive motor, and the flipping mechanism includes a flipping frame and a cylinder. Although this device achieves the basic conveying and flipping functions of circuit boards, it still has the following problems in practical applications: First, the conveying mechanism only uses conveying rollers and lacks a positioning structure, resulting in poor stability of the substrate conveying; second, the flipping mechanism is driven by a cylinder, resulting in low flipping angle accuracy, which cannot meet the requirements of high-precision processing; third, it lacks an effective safety protection structure, resulting in insufficient safety; and fourth, it cannot adapt to circuit boards of different specifications, resulting in a narrow range of applications. Summary of the Invention

[0005] The purpose of this invention is to provide a circuit board processing flipping machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a circuit board processing flipping machine, comprising a base frame, a top frame, a protective shell, and a vertical frame.

[0009] Furthermore, the circuit board surface processing flipping unit also includes a flipping part, which includes a mounting frame. The mounting frame is fixedly mounted on one side of the vertical frame by bolts. A telescopic cylinder is horizontally mounted on the side of the mounting frame away from the vertical frame. A moving frame is fixed to the moving end of the telescopic cylinder by a flange. A fixed frame is integrally formed on one side of the moving frame. A stepper motor is mounted on the fixed frame by a motor mount. A turntable sleeve is installed through the surface of the moving frame.

A rotating frame is fixedly mounted on the other rotating end of the turntable sleeve.

[0010] Furthermore, the flipping part also includes strip-shaped blocks, which are symmetrically arranged in two groups. The two groups of strip-shaped blocks are symmetrically installed on the side of the rotating frame away from the turntable sleeve. A vertical guide rail is installed on the surface of the strip-shaped blocks along the length direction. A slider is slidably installed on the moving end of the vertical guide rail. A latch is detachably installed on one side of the slider by a buckle. A pressure plate is fixedly installed on one side of the latch. A fixing seat three is welded to one side of the pressure plate. An embedded groove is opened on the surface of the pressure plate. An electric drive roller two is installed on one side of the fixing seat three. A top mounting plate is fixedly installed on the rotating end of the electric drive roller two. An electromagnetic chuck two is embedded in the surface of the top mounting plate, and the electromagnetic chuck two is arranged vertically corresponding to the electromagnetic chuck one.

[0011] Furthermore, the protective shell is made of transparent acrylic material, and an openable inspection door is hinged to one side of the protective shell. The inspection door is equipped with a safety lock and an observation window, and multiple sets of buffer pads are evenly installed on the inner wall of the protective shell.

[0012] Furthermore, adjustable support feet are installed at the four corners of the bottom of the base frame. Each adjustable support foot includes a screw and a foot pad.

A wire outlet is provided on one side of the base frame, and a protective sleeve is installed at the wire outlet.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, a dedicated bottom conveying unit for circuit board processing substrates is set up. Two sets of parallel guide rails drive the moving disk to move, and multiple sets of electrically driven rollers drive the rotating arm and bottom mounting disk to rotate, realizing multi-directional conveying and angle adjustment of the substrate. At the same time, the electromagnetic chuck on the surface of the bottom mounting disk can adsorb and position the substrate, effectively preventing the substrate from shifting or shaking during conveying, improving conveying stability, especially suitable for conveying thin circuit boards, reducing the risk of substrate damage. The setting of the balance block can adjust the balance performance of the bottom mounting disk, avoiding the conveying tilt problem caused by uneven substrate weight, further improving conveying stability. 2. In use, the system employs a coordinated design between the moving and flipping sections. The moving section, driven by guide rails, moves the moving disk, working in conjunction with a vacuum suction cup to precisely grip the substrate. The flipping section, driven by a telescopic cylinder, moves the moving frame, causing the rotating frame to move closer to or away from the substrate. A stepper motor drives the turntable sleeve and rotating frame to rotate, achieving substrate flipping. An angle encoder is installed to detect the flipping angle in real time and feed it back to the controller, achieving 180-degree precise flipping, improving flipping accuracy and meeting high-precision processing requirements. Furthermore, the strip blocks, vertical guide rails, and sliders in the flipping section allow adjustment of the height of the top mounting plate, adapting to circuit boards of different thicknesses and enhancing the equipment's compatibility. 3. When in use, the transparent acrylic material does not affect the operator's observation of the equipment's operating status, and can effectively isolate moving parts to prevent collision accidents; the installation of inspection doors and safety locks facilitates equipment inspection and maintenance, while improving equipment safety; the buffer pad can absorb vibration during equipment operation, reduce component wear, and extend the equipment's service life. 4. During use, the position sensor can detect the movement position of the second moving disk in real time. When the second moving disk moves to the extreme positions at both ends of the second guide rail, the sensor sends a signal to the controller to control the second moving disk to stop moving, preventing damage from collisions and improving the safety and stability of the equipment operation.

[0023] Please see Figure 1-6 The present invention provides a technical solution: like Figure 1-6 As shown, this embodiment provides a circuit board processing flipping machine, including a base frame 1, a top frame 2, a protective shell 3, and a vertical frame 6. The top frame 2 is fixedly installed on the top of the base frame 1 by bolts. The protective shell 3 covers and is installed on the outside of the base frame 1 and the top frame 2. The protective shell 3 is made of transparent acrylic material, which has good transparency and impact resistance, making it convenient for operators to observe the internal operating status of the equipment and effectively protecting the internal components. A hinged maintenance door is connected to one side of the protective shell 3. The maintenance door is equipped with a safety lock and an observation window. The safety lock prevents the maintenance door from being accidentally opened during equipment operation, improving safety; the observation window further facilitates operators to observe the details of equipment operation. Multiple sets of buffer pads are evenly installed on the inner wall of the protective shell 3. The buffer pads are made of rubber material and can absorb vibration during equipment operation, reduce collision and wear between components, and extend the service life of the equipment.

[0024] Adjustable support feet are installed at each of the four corners of the base frame 1. Each adjustable support foot consists of a screw and a foot pad. One end of the screw is threaded to the bottom of the base frame 1, and the other end is rotatably connected to the foot pad via a bearing. Rotating the screw adjusts the height of the adjustable support foot, thereby adjusting the overall height of the equipment according to the flatness of the site and ensuring the stability of the equipment operation. The foot pads are made of rubber with anti-slip textures on the bottom, enhancing the friction between the equipment and the ground and preventing displacement of the equipment during operation.

[0025] The vertical frame 6 is fixedly installed in the center area of ​​the top of the top frame 2 by welding, and is used to install the flipping part structure. This flipping machine also includes a circuit board processing substrate bottom conveying unit and a circuit board surface processing flipping unit. The circuit board processing substrate bottom conveying unit is located in the bottom area of ​​the base frame 1 and is used to convey and transfer the substrate required for circuit board processing; the circuit board surface processing flipping unit is located in the surface area of ​​the top frame 2 and is used to grasp and transfer the substrate material required for processing after conveying it, and flip it after processing to achieve the purpose of flipping the substrate material.

[0026] The circuit board processing substrate bottom conveying unit includes guide rail 4, which is a linear guide rail, arranged in two parallel sets. The two sets of guide rail 4 are symmetrically mounted on the surface of the base frame 1 by bolts. A movable disk 41 is fixedly mounted on the moving end of adjacent guide rail 4 by bolts. The guide rail 4 can drive the movable disk 41 to move along the length of the guide rail. Multiple sets of electrically driven rollers 42 are evenly mounted on the movable disk 41. The electrically driven rollers 42 are fixed to the movable disk 41 by motor mounts. A rotating arm 43 is fixedly mounted on the rotating end of the electrically driven roller 42 by a key connection. The electrically driven roller 42 can drive the rotating arm 43 to rotate around its axis. A bottom mounting plate 8 is bolted to the end of the rotating arm 43 away from the electrically driven roller 42. An electromagnetic chuck 81 is embedded in the surface of the bottom mounting plate 8. The electromagnetic chuck 81 is electrically connected to an external power source. When energized, it generates magnetic force to attract and position the substrate, preventing the substrate from shifting or shaking during transport. The bottom mounting plate 8 has a fixed base 82 integrally formed at one end. The side of the fixed base 82 away from the bottom mounting plate 8 is detachably mounted with a balance block 83 by bolts. The balance block 83 is made of cast iron. The number and installation position of the balance block 83 can be adjusted according to the weight and specifications of the substrate to adjust the balance performance of the bottom mounting plate 8 and avoid the problem of conveying tilt caused by uneven weight of the substrate.

[0027] The circuit board surface processing flipping unit includes a moving part, which includes a second guide rail 5. The second guide rail 5 is also a linear guide rail, symmetrically mounted on the surface of the top frame 2 and arranged perpendicular to the first guide rail 4. A second moving disk 51 is fixedly mounted on the moving end of the adjacent second guide rail 5 by bolts. The second guide rail 5 can drive the second moving disk 51 to move along the length of the guide rail, realizing the lateral transport of the substrate. A second fixing seat 52 is welded to one side of the second moving disk 51 to enhance the structural strength of the second moving disk 51. Several sets of fixed suction cups 53 are evenly arranged on the surface of the second moving disk 51 facing the substrate. The fixed suction cups 53 are vacuum suction cups, which are connected to an external negative pressure device through air pipes. When the negative pressure device is working, a negative pressure is generated in the fixed suction cups 53, thereby adsorbing the substrate and realizing the gripping of the substrate.

[0028] The top frame 2 is also equipped with position sensors, which include infrared transmitters and receivers. These are mounted on both ends of the guide rail 2 5 via brackets, and the position sensors are configured to correspond to the movement trajectory of the moving disk 2 51. The position sensors are electrically connected to an external controller. When the moving disk 2 51 moves to the extreme positions at both ends of the guide rail 2 5, the infrared signal emitted by the infrared transmitter is blocked by the moving disk 2 51, and the infrared receiver cannot receive the signal. At this time, the position sensor sends a signal to the controller, and the controller controls the guide rail 2 5 to stop working, preventing the moving disk 2 51 from colliding with the ends of the guide rail 2 5, thus improving the safety and stability of the equipment operation.

[0029] The circuit board surface processing flipping unit also includes a flipping section, which includes a mounting frame 7. The mounting frame 7 is fixedly mounted on one side of the vertical frame 6 by bolts. A telescopic cylinder 71 is horizontally mounted on the side of the mounting frame 7 away from the vertical frame 6. A moving frame 9 is fixed to the moving end of the telescopic cylinder 71 by a flange. When the telescopic cylinder 71 is working, it can drive the moving frame 9 to move horizontally, causing the flipping section to move closer to or away from the substrate. A fixed frame 91 is integrally formed on one side of the moving frame 9. A stepper motor 92 is mounted on the fixed frame 91 by a motor mount. The stepper motor 92 is a high-precision stepper motor, which has the characteristics of high control accuracy and stable operation. A turntable sleeve 911 is installed through the surface of the moving frame 9. The turntable sleeve 911 is rotatably connected to the moving frame 9 by bearings. One rotating end of the turntable sleeve 911 is fixedly connected to the rotating end of the stepper motor 92 by a coupling. The other rotating end of the turntable sleeve 911 is fixedly mounted to a rotating frame 93 by bolts. When the stepper motor 92 is working, it drives the turntable sleeve 911 to rotate through the coupling, which in turn drives the rotating frame 93 to rotate, thereby realizing the flipping of the substrate.

[0030] An angle encoder is installed on the rotating frame 93. The angle encoder is fixed on the rotating frame 93 by a bracket. The angle encoder is electrically connected to the stepper motor 92. It is used to detect the flip angle of the rotating frame 93 in real time and feed the detection signal back to the controller. The controller adjusts the rotation angle of the stepper motor 92 according to the feedback signal to achieve precise control of the flip angle and ensure that the substrate can be flipped 180 degrees accurately.

[0031] The flipping section also includes strip blocks 94, which are symmetrically arranged in two groups. The two groups of strip blocks 94 are symmetrically installed on the side of the rotating frame 93 away from the turntable sleeve 911 by bolts. Vertical guide rails 95 are bolted to the surface of the strip blocks 94 along their length. A slider 96 is slidably installed on the moving end of the vertical guide rail 95, and the slider 96 can move up and down along the vertical guide rail 95. A latch 98 is detachably installed on one side of the slider 96 via a clip 97. A pressure plate 981 is bolted to one side of the latch 98. By adjusting the position of the slider 96 on the vertical guide rail 95, the height of the pressure plate 981 and the top mounting plate 99 can be adjusted to accommodate circuit boards of different thicknesses, enhancing the equipment's adaptability. A fixing seat 982 is welded to one side of the pressure plate 981. An embedded groove 983 is formed on the surface of the pressure plate 981, which can be used to accommodate some components, saving installation space. One side of the fixed base 982 is equipped with an electrically driven roller 984 via a motor mount. A top mounting plate 99 is fixedly mounted on the rotating end of the electrically driven roller 984 via a key connection. An electromagnetic chuck 991 is embedded in the surface of the top mounting plate 99. The electromagnetic chuck 991 is electrically connected to an external power source and is vertically aligned with the electromagnetic chuck 81. When the substrate is transported to the flipping position, the electromagnetic chuck 991 is energized to generate magnetic force, which, in conjunction with the electromagnetic chuck 81, attracts and fixes the substrate vertically, preventing displacement or detachment during the flipping process and further improving flipping stability and accuracy.

[0032] The base frame 1 has an internal wiring channel for storing the wiring harnesses of various electric drive components, such as electric drive roller 1, electric drive roller 2, stepper motor, telescopic cylinder, and sensors such as position sensors and angle encoders. Several sets of wire clips, made of plastic, are installed inside the wiring channel and are bolted to the inner wall of the channel. This allows for the categorized and secure fixing of the wire harnesses, preventing wear, short circuits, and other malfunctions caused by tangled wires. A cable exit is located on one side of the base frame 1, fitted with a rubber protective sleeve. This sleeve protects the wire harness from wear and tear at the exit edge, further improving the equipment's operational stability and lifespan.

[0033] Working principle: First, the operator adjusts the equipment parameters according to the specifications of the circuit board to be processed. The height of the equipment is adjusted by rotating the screws of the adjustable support feet to ensure stable placement. The height of the top mounting plate 99 is adjusted by adjusting the position of the slider 96 on the vertical guide rail 95 to match the substrate thickness. The number and installation position of the balance blocks 83 are adjusted according to the substrate weight to ensure the balance of the bottom mounting plate 8. The substrate to be processed is placed on the bottom mounting plate 8, and the electromagnetic chuck 81 is energized to generate magnetic force, adsorbing and positioning the substrate. Subsequently, the controller controls the guide rail 4 to work, driving the moving disk 41 to move along the length of the guide rail 4, conveying the substrate to the gripping position. During this process, the electrically driven roller 42 can drive the rotating arm 43 to rotate as needed, adjusting the angle of the substrate to ensure precise alignment. When the substrate reaches the gripping position, the guide rail 5 operates, driving the moving disk 51 to move above the substrate. The external negative pressure device operates, generating negative pressure inside the fixed suction cup 53 to adsorb the substrate and achieve gripping. At the same time, the electromagnetic chuck 81 is de-energized, releasing the adsorption on the substrate. Then, the guide rail 5 continues to work, conveying the substrate to the flipping position. The position sensor detects the position of the moving disk 51 in real time. When the moving disk 51 reaches the flipping position, the position sensor sends a signal to the controller, and the controller controls the guide rail 5 to stop working. Then, the telescopic cylinder 71 operates, driving the moving frame 9 and the rotating frame 93 to move towards the substrate, bringing the top mounting plate 99 close to the substrate. The electromagnetic chuck 991 is energized to generate magnetic force, adsorbing and fixing the substrate. Simultaneously, the external negative pressure device stops working, the fixing chuck 53 releases its adsorption of the substrate, and the guide rail 5 drives the moving plate 51 to reset. Afterwards, the stepper motor 92 operates, driving the turntable sleeve 911 and the rotating frame 93 to rotate via the coupling, causing the substrate to flip. The angle encoder detects the flip angle in real time and feeds it back to the controller. When the substrate flips to 180 degrees, the controller stops the stepper motor 92. After the flip is complete, the telescopic cylinder 71 operates, driving... The rotating frame 93 resets, and the guide rail 2 5 drives the moving disk 2 51 to move above the substrate. The fixed suction cup 53 adsorbs the substrate, and the electromagnetic suction cup 2 991 is de-energized, releasing the adsorption on the substrate. Finally, the guide rail 2 5 drives the moving disk 2 51 to transport the flipped substrate to the next processing step. At the same time, the guide rail 1 4 drives the moving disk 1 41 to reset, preparing for the next substrate transport. This cycle is repeated to achieve continuous flipping processing of the circuit board. During the entire operation of the equipment, the protective shell 3 effectively isolates the moving parts to prevent collision accidents for the operator. The buffer pad absorbs equipment vibration and reduces component wear. The wiring trough and wire clips store and fix the wire bundles to ensure stable operation of the equipment.
