Description

Technical Field

[0001] This utility model belongs to the field of PCB board processing technology, specifically relating to a PCB board encoding and transfer device. Background Technology

[0002] A laser engraving machine is a machine that cuts, engraves, and labels materials. It uses laser technology to achieve high-precision engraving and cutting of patterns, text, and designs on various materials, including wood, plastic, leather, metal, glass, and ceramics.

[0003] The PCB board processing often requires laser engraving to encode the PCB board. After encoding, the PCB board needs to be transferred to the receiving rack of the receiving machine. With the development of automation and artificial intelligence, the transfer of PCB boards has evolved into the use of robotic arms. That is, tooling fixtures are installed at the operating end of the robotic arm to clamp the PCB board. When clamping the PCB board, the rigidity of the clamping process needs to be considered to avoid damage to the PCB board due to rigid clamping. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PCB board encoding and transfer device. During the clamping process of the PCB board, the buffer plate and the spring play a buffering role, which reduces the rigid clamping between the buffer plate and the clamping plate to a certain extent, thereby protecting the PCB board.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A PCB board encoding and transfer device, including:

[0007] A substrate, wherein a bidirectional lead screw is disposed below the substrate, and the two ends of the bidirectional lead screw are rotatably connected to the two ends of the substrate.

[0008] The movable plate has two sets of movable plates threadedly connected to different helical directions of a bidirectional lead screw. Fixed plates are fixedly connected to both ends of the movable plate, and a connecting plate is fixedly connected to the lower end of the fixed plate. A support plate is fixedly connected to the side of the connecting plate. Slide rods are provided at both ends below the support plate. A slider is slidably connected to the slide rod, and a spring is also sleeved on the slide rod. A connecting rod is rotatably connected to the lower end of the slider, and a buffer plate is rotatably connected to the other end of the connecting rod.

[0009] A clamping plate is disposed below a buffer plate. A cylinder is fixedly connected to the connecting plate. The telescopic end of the cylinder passes through the connecting plate and is fixedly connected to the clamping plate. The vertical downward projection of the buffer plate coincides with the clamping plate.

[0010] The principles and technical effects of the above technical solution are as follows:

[0011] The substrate is mounted on the operating end of the robot arm. After the PCB board is coded, the robot arm moves the operating substrate directly above the PCB board, with the clamping plates positioned on both sides of the PCB board. The PCB board is placed on the worktable, with its sides extending out of the worktable to facilitate insertion between the clamping plates and the buffer plate. The drive source drives the bidirectional lead screw to rotate, causing the two sets of moving plates to move towards the center of the bidirectional lead screw. The moving plates drive the fixed plate to move, the fixed plate drives the connecting plate to move, the connecting plate drives the support plate to move, the support plate drives the slide bar to move, the slide bar drives the slider to move, the slider drives the connecting rod to move, and the connecting rod drives the buffer plate to move. Simultaneously, the connecting plate drives the cylinder to move, the cylinder drives the clamping plate to move, and the buffer plate and clamping plate move synchronously towards the PCB board until the side of the PCB board is between the buffer plate and the clamping plate. The bidirectional lead screw stops rotating, and then the driving cylinder drives the clamping plate to move upward until the buffer plate and clamping plate clamp the PCB board. During the clamping process, as the buffer plate moves upward toward the support plate, the connecting rod pushes the slider to slide. At this time, the spring is compressed and contracts. During this process, the elasticity of the spring plays a buffering role, which to a certain extent reduces the rigid clamping between the buffer plate and the clamping plate, thereby protecting the PCB board.

[0012] In a preferred embodiment, the present invention can be further configured such that a raised flange mounting base is fixedly connected to the upper end of the substrate.

[0013] In a preferred embodiment, the present invention can be further configured such that: a plurality of first ear plates are fixedly connected to both ends of the substrate, and both ends of the bidirectional lead screw are rotatably connected to the first ear plates.

[0014] In a preferred embodiment, the present invention can be further configured such that: guide rods are arranged parallel to each other on both sides of the bidirectional lead screw, the guide rods pass through the movable plate so that the guide rods are slidably connected to the movable plate, and the two ends of the guide rods are fixedly connected to the first ear plate.

[0015] In a preferred embodiment, the present invention can be further configured such that: a motor is fixedly connected to the upper surface of one end of the substrate, a first synchronous pulley is fixedly connected to the output end of the motor, a second synchronous pulley is fixedly connected to the end of the bidirectional lead screw, and a synchronous belt meshes between the first synchronous pulley and the second synchronous pulley.

[0016] In a preferred embodiment, the present invention can be further configured such that: a second ear plate is fixedly connected to both ends of the slide rod, and the second ear plate is fixedly connected to the support plate.

[0017] In a preferred embodiment, the present invention can be further configured such that: the upper end of the clamping plate is fixedly connected to limit rods on both sides of the cylinder, and the limit rods pass through the connecting plate so that the limit rods are slidably connected to the connecting plate.

[0018] In a preferred embodiment, the present invention can be further configured such that the slider and the support plate are in contact with each other.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0020] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0021] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0022] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0023] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together as one unit.

[0024] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.

[0025] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] The beneficial effects of this utility model are:

[0027] During the clamping process of the PCB board, the buffer plate and spring play a buffering role, which reduces the rigid clamping between the buffer plate and the clamping plate to a certain extent, thereby protecting the PCB board. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Based on the concept of this application, combined with Figures 1 to 3 This describes an embodiment of a PCB board encoding and transfer device. Specifically, the PCB board encoding and transfer device is constructed as a split structure, comprising a substrate 1, a moving plate 3, and a clamping plate 12. Through the cooperation of a slider 8, a spring 9, a connecting rod 10, and a buffer plate 11, the substrate 1 is mounted on the operating end of a robotic arm. After the PCB board 23 is encoded, the robotic arm moves the substrate 1 to directly above the PCB board 23, with the clamping plates 12 positioned on both sides of the PCB board 23. Figure 1As shown, PCB board 23 is located on worktable 24, with both sides of PCB board 23 extending out of worktable 24, facilitating insertion of both sides of PCB board 23 between clamping plate 12 and buffer plate 11. A drive source drives bidirectional lead screw 2 to rotate, causing two sets of moving plates 3 to move towards the center of bidirectional lead screw 2. Moving plate 3 drives fixed plate 4 to move, fixed plate 4 drives connecting plate 5 to move, connecting plate 5 drives support plate 6 to move, support plate 6 drives slide rod 7 to move, slide rod 7 drives slider 8 to move, slider 8 drives connecting rod 10 to move, connecting rod 10 drives buffer plate 11 to move. Simultaneously, connecting plate 5 drives cylinder 13 to move, cylinder 13 drives clamping plate 12 to move, and the buffer plate 11... The punch plate 11 and the clamping plate 12 move synchronously toward the PCB board 23 until the side of the PCB board 23 is between the buffer plate 11 and the clamping plate 12. The bidirectional lead screw 2 stops rotating, and then the drive cylinder 13 drives the clamping plate 12 to move upward until the buffer plate 11 and the clamping plate 12 clamp the PCB board 23. During the clamping process, as the buffer plate 11 moves upward toward the support plate 6, the connecting rod 10 pushes the slider 8 to slide. At this time, the spring 9 is compressed and contracts. During this process, the elasticity of the spring 9 plays a buffering role, which to a certain extent reduces the rigid clamping between the buffer plate 11 and the clamping plate 12, thereby protecting the PCB board 23.

[0035] like Figure 1-3 As shown, the PCB board coding and transfer device includes:

[0036] A substrate 1 is provided on the bottom of the substrate 1, and the two ends of the bidirectional lead screw 2 are rotatably connected to the two ends of the substrate 1.

[0037] The movable plate 3 has two sets of movable plates 3 threadedly connected to the two-way lead screw 2 in different directions. The two ends of the movable plate 3 are fixedly connected to the fixed plate 4. The lower end of the fixed plate 4 is fixedly connected to the connecting plate 5. The side of the connecting plate 5 is fixedly connected to the support plate 6. The two ends below the support plate 6 are provided with slide rods 7. The slide rods 7 are fitted with sliding sliders 8. The slide rods 7 are also fitted with springs 9. The lower end of the slider 8 is rotatably connected to the connecting rod 10. The other end of the connecting rod 10 is rotatably connected to the buffer plate 11.

[0038] A clamping plate 12 is located below the buffer plate 11. A cylinder 13 is fixedly connected to the connecting plate 5. The telescopic end of the cylinder 13 passes through the connecting plate 5 and is fixedly connected to the clamping plate 12. The vertical downward projection of the buffer plate 11 coincides with the clamping plate 12.

[0039] In use, the substrate 1 is mounted on the operating end of the robot arm. After the PCB board 23 is encoded, the robot arm moves the substrate 1 to directly above the PCB board 23, with the clamping plates 12 positioned on both sides of the PCB board 23. Figure 1As shown, PCB board 23 is located on worktable 24, with both sides of PCB board 23 extending out of worktable 24, facilitating insertion of both sides of PCB board 23 between clamping plate 12 and buffer plate 11. A drive source drives bidirectional lead screw 2 to rotate, causing two sets of moving plates 3 to move towards the center of bidirectional lead screw 2. Moving plate 3 drives fixed plate 4 to move, fixed plate 4 drives connecting plate 5 to move, connecting plate 5 drives support plate 6 to move, support plate 6 drives slide rod 7 to move, slide rod 7 drives slider 8 to move, slider 8 drives connecting rod 10 to move, connecting rod 10 drives buffer plate 11 to move. Simultaneously, connecting plate 5 drives cylinder 13 to move, cylinder 13 drives clamping plate 12 to move, and the buffer plate 11... The punch plate 11 and the clamping plate 12 move synchronously toward the PCB board 23 until the side of the PCB board 23 is between the buffer plate 11 and the clamping plate 12. The bidirectional lead screw 2 stops rotating, and then the drive cylinder 13 drives the clamping plate 12 to move upward until the buffer plate 11 and the clamping plate 12 clamp the PCB board 23. During the clamping process, as the buffer plate 11 moves upward toward the support plate 6, the connecting rod 10 pushes the slider 8 to slide. At this time, the spring 9 is compressed and contracts. During this process, the elasticity of the spring 9 plays a buffering role, which to a certain extent reduces the rigid clamping between the buffer plate 11 and the clamping plate 12, thereby protecting the PCB board 23.

[0040] In one embodiment of this utility model, a raised flange mounting base 14 is fixedly connected to the upper end of the base plate 1. The raised flange mounting base 14 is used to be installed at the operating end of the robot arm, providing a suitable operating distance between the base plate 1 and the robot arm to avoid structural conflicts during the operation of the robot arm.

[0041] In one embodiment of this utility model, a plurality of first ear plates 15 are fixedly connected to both ends of the substrate 1, and both ends of the bidirectional lead screw 2 are rotatably connected to the first ear plates 15. The first ear plates 15 are provided to connect the bidirectional lead screw 2, so that the bidirectional lead screw 2 can rotate smoothly.

[0042] In one embodiment of this utility model, guide rods 16 are arranged parallel to each other on both sides of the bidirectional lead screw 2. The guide rods 16 pass through the movable plate 3, so that the guide rods 16 and the movable plate 3 are slidably connected. The two ends of the guide rods 16 are fixedly connected to the first ear plate 15. When the movable plate 3 moves, the two ends of the movable plate 3 slide along the guide rods 16, so that the movable plate 3 can move smoothly, which facilitates the insertion of both sides of the PCB board between the clamping plate 12 and the buffer plate 11.

[0043] In one embodiment of this utility model, a motor 17 is fixedly connected to the upper surface of one end of the substrate 1. A first synchronous pulley 18 is fixedly connected to the output end of the motor 17, and a second synchronous pulley 19 is fixedly connected to the end of the bidirectional lead screw 2. A synchronous belt 20 meshes between the first synchronous pulley 18 and the second synchronous pulley 19. The motor 17, as a drive source, drives the first synchronous pulley 18 to rotate. Through the transmission of the synchronous belt 20 and the second synchronous pulley 19, the bidirectional lead screw 2 is driven to rotate. The rotation of the bidirectional lead screw 2 drives the two moving plates 3 to move towards each other, so that the buffer plate 11 and the clamping plate 12 move synchronously towards the PCB board, thereby allowing the side of the PCB board to be inserted between the buffer plate 11 and the clamping plate 12, facilitating subsequent clamping.

[0044] In one embodiment of this utility model, second ear plates 21 are fixedly connected to both ends of the slide rod 7, and the second ear plates 21 are fixedly connected to the support plate 6. By fixing the slide rod 7 and the support plate 6 together, when the support plate 6 moves, it can drive the buffer plate 11 to move.

[0045] In one embodiment of this utility model, the upper end of the clamping plate 12 is fixedly connected to the two sides of the cylinder 13 with limiting rods 22. The limiting rods 22 pass through the connecting plate 5, so that the limiting rods 22 and the connecting plate 5 are slidably connected. When the clamping plate 12 moves up and down, the limiting rods 22 slide with the connecting plate 5. The setting of the limiting rods 22 improves the stability of the clamping plate 12 when it is raised and lowered.

[0046] In one embodiment of this invention, the slider 8 and the support plate 6 are in close contact with each other. This design reduces the gap between the slider 8 and the support plate 6, thereby reducing the wobbling of the slider 8 and improving its stability when it moves.
