Description

Technical Field

[0001] This invention relates to the field of PCB boards, and more particularly to a handling arm for PCB substrates. Background Technology

[0002] A PCB, also known as a printed circuit board, is a provider of electrical connections for electronic components. Printed circuit boards are often referred to as "PCBs" rather than simply "PCB boards." The design of a PCB primarily involves layout design. The main advantages of using PCBs are significantly reduced wiring and assembly errors, improved automation, and increased production efficiency. PCBs can be categorized by the number of layers: single-sided, double-sided, four-layer, six-layer, and other multi-layer PCBs. Because PCBs are not typically end products, their terminology is somewhat ambiguous. For example, the motherboard used in personal computers is called a motherboard, not simply a circuit board. Although motherboards contain circuit boards, they are not the same. Therefore, while related, they are not identical when evaluating the industry. Furthermore, because integrated circuit components are mounted on the circuit board, the media refers to it as an IC board, but this is not the same as a printed circuit board. The PCB we usually refer to is a bare board, i.e., a circuit board without any components mounted on it.

[0003] PCB board inspection typically measures the impedance characteristics between test points to check for continuity. It can be mainly divided into two categories: visual testing and electrical testing. Visual testing uses a magnifying glass or a calibrated microscope to determine whether the board is qualified by visual inspection by the operator and to determine when correction operations are needed. Electrical performance testing identifies manufacturing defects and tests analog, digital and mixed signal components to ensure they meet specifications.

[0004] Traditional visual testing methods have the main advantage of low initial cost. When inspecting PCB boards, the manual person places the PCB board on the table and uses instruments to inspect it. When inspecting a large number of PCB boards, manual handling increases labor intensity and is quite cumbersome.

[0005] Therefore, it is necessary to provide a handling arm for PCB substrates to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a handling arm for PCB substrates, which solves the problem that when manually placing PCB boards on a table and using instruments to inspect them, the manual handling of a large number of PCB boards increases labor intensity and is quite cumbersome.

[0007] To solve the above-mentioned technical problems, the present invention provides a handling arm for a PCB substrate, comprising: a mounting plate;

[0008] A fixing device is fixedly installed on one side of the bottom of the mounting plate. The fixing device is provided with a pushing device inside, and the bottom of the pushing device is fixedly installed with an installation device.

[0009] A drive device is rotatably mounted inside the mounting device, and both sides of the surface of the drive device are threaded with threaded devices.

[0010] Preferably, the fixing device includes a fixing column, a setting hole is provided in the middle of the bottom of the fixing column, and sliders are fixedly installed on both sides of the inner cavity of the setting hole.

[0011] Preferably, the pushing device includes a mounting column, a telescopic cylinder is fixedly installed inside the mounting column, a push plate is fixedly connected to the top of the output shaft of the telescopic cylinder, and sliding grooves are provided on both sides of the outer surface of the mounting column.

[0012] Preferably, the mounting device includes a mounting block, and a movable groove is provided in the middle of the bottom of the mounting block.

[0013] Preferably, the threaded device includes a clamping plate, a movable block is fixedly mounted on the top of the clamping plate, and a threaded hole is provided inside the movable block.

[0014] Preferably, the driving device includes a first servo motor, and the output shaft of the first servo motor is fixedly connected to a reciprocating lead screw.

[0015] Preferably, a fixing plate is fixedly installed on one side of the mounting plate, a base is fixedly installed on the bottom of the fixing plate, and a storage battery is fixedly installed in the middle of the top of the base.

[0016] During operation, the user first controls the output shaft of the first servo motor to rotate via an external power source, which in turn drives the reciprocating lead screw to rotate. The reciprocating lead screw rotates and engages with the threaded holes of the moving blocks on the left and right sides of the outer surface. The two moving blocks are restricted by the moving slots and can only approach each other at the same speed, so that the two moving blocks clamp the two sides of the PCB board.

[0017] The battery controls the movement of the base's wheels to move the clamped PCB board. Once the board is in the correct position, the output shaft of the telescopic cylinder is pushed upwards by the external power supply to lower the height of the mounting device. The output shaft of the first servo motor is then rotated in the opposite direction by the external power supply, causing the reciprocating screw to rotate in the opposite direction and engage the threaded hole of the moving block. This causes the left and right moving blocks to move away from each other at the same speed and in the opposite direction, thus releasing the PCB board.

[0018] Preferably, the top of the mounting plate is provided with a meshing device, the meshing device includes a mounting box, a second servo motor is fixedly connected inside the mounting box, the output shaft of the second servo motor is fixedly connected to a drive gear, and a rotating device is meshed on one side of the meshing device.

[0019] Preferably, the rotating device includes a rotating wheel, a rotating rod is fixedly connected to the middle of the rotating wheel, and a driven gear is fixedly connected to the middle of the outer surface of the rotating wheel.

[0020] Preferably, a protective device is fixedly connected to one side of the clamping plate. The protective device includes a protective pad, and a protrusion is fixedly connected to the surface of the protective pad.

[0021] Compared with related technologies, the PCB substrate handling arm provided by the present invention has the following advantages:

[0022] This invention provides a handling arm for PCB substrates. The output shaft of the first servo motor is controlled by an external power source to rotate, which drives the reciprocating lead screw to rotate and engage the clamping plates on the left and right sides of the outer surface. The plates move towards the center to clamp the PCB board or separate and lower the PCB board at the same time. This device has a simple structure and is highly practical. It can clamp and move PCB boards of different sizes, using machinery to replace manual labor and reduce the labor intensity of manual handling.

[0023] This invention provides a handling arm for PCB substrates. The output shaft of a second servo motor is controlled by an external power source to rotate, which drives the drive gear to mesh with the driven gear. The rotation of the rotating device drives the threaded device to rotate. The clamping angle can be adjusted according to the size of the PCB board to be clamped. This device has a simple structure and is highly practical. The clamping angle can be adjusted according to the angle at which the PCB board is placed. At the same time, the placement angle can also be adjusted during placement, which improves the practicality and flexibility of the device during handling.

[0024] This invention provides a handling arm for PCB substrates. By fixing a rubber protective pad to the side of two clamping plates that are close to each other, this device has a simple structure and strong practicality. It can increase the protection of the PCB board when clamping, avoid excessive clamping force that could damage the PCB board, and improve the safety of handling the PCB board.

[0038] The fixing device 2 includes a fixing post 21, and a setting hole 22 is provided in the middle of the bottom of the fixing post 21. Slider 23 is fixedly installed on both sides of the inner cavity of the setting hole 22.

[0039] Two sliders 23 are fixed on the left and right sides of the bottom of the inner cavity of the setting hole 22, respectively.

[0041] The output shaft of the telescopic cylinder 32 is connected to the push plate 34 facing upwards. The push plate 34 is fixed to the top of the inner cavity of the setting hole 22. Two sliding grooves 33 are respectively set on the left and right sides of the outer surface of the mounting column 31.

[0042] The mounting device 4 includes a mounting block 41, and a movable groove 42 is provided in the middle of the bottom of the mounting block 41.

[0043] The threaded device 5 includes a clamping plate 51, and a movable block 52 is fixedly installed on the top of the clamping plate 51. The movable block 52 has a threaded hole 53 inside.

[0044] The movable slot 42 and the movable block 52 are adapted to each other, restricting the movable block 52 to move left and right only inside the movable slot 42.

[0045] The moving block 52 is threadedly engaged with the outer surface of the reciprocating lead screw 62 through the threaded hole 53.

[0046] The drive device 6 includes a first servo motor 61, and the output shaft of the first servo motor 61 is fixedly connected to a reciprocating lead screw 62.

[0047] As the output shaft of the first servo motor 61 rotates, it drives the reciprocating lead screw 62 to rotate. When the reciprocating lead screw 62 rotates, the threads engage with the threaded holes 53 of the moving blocks 52 on the left and right sides of the outer surface, and the two moving blocks 52 move closer to each other or separate from each other.

[0052] The battery 9 can control the movement of the base 8's moving wheels to move the clamped PCB board. After moving it to the appropriate position, the output shaft of the telescopic cylinder 32 is pushed upward by the external power supply to lower the height of the mounting device 4. The output shaft of the first servo motor 61 is rotated in the opposite direction by the external power supply, and the reciprocating screw 62 rotates in the opposite direction to engage the threaded hole 53 of the moving block 52, so that the left and right moving blocks 52 move away from each other at the same speed and in the opposite direction, releasing the PCB board.

The output shaft of the first servo motor 61 is controlled by an external power source to rotate, which drives the reciprocating lead screw 62 to rotate and engage the clamping plates 51 on the left and right sides of the outer surface. At the same time, the plates move towards the center to clamp the PCB board or separate and put the PCB board down. This device has a simple structure and is highly practical. It can clamp and move PCB boards of different sizes, using machinery to replace manual labor and reduce the labor intensity of manual handling.

The top end of rotating rod 112 is rotatably connected to mounting plate 1. The bottom end of rotating rod 112 is connected to fixed column 21.

[0061] The working principle of the PCB substrate handling arm provided by this invention is as follows:

[0062] During operation, the output shaft of the second servo motor 102 is first controlled by an external power source to rotate, which drives the drive gear 103 to rotate.

[0069] The working principle of the PCB substrate handling arm provided by this invention is as follows:

[0070] During operation, the protective pad 121 first uses the softness of the rubber material to reduce the strength of the clamping plate 51 on the PCB board.
