Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a PCB board transfer platform. Background Art

[0002] PCB is the abbreviation of printed circuit board, which is a basic component used to support and connect electronic components. PCB board is usually a board made of insulating material, covered with a circuit pattern formed by conductive material, which is used to connect and support electronic components such as resistors, capacitors, integrated circuits, etc. These electronic components are connected to the wires, pads or jacks on the PCB board by welding or insertion to form a complete circuit.

[0003] At present, in the processing of PCB boards, a transfer platform is needed to turn over the PCB boards. The PCB boards are mainly clamped and fixed by a flippable fixture, then flipped 180 degrees and placed on a conveyor line for transportation. Then, the PCB boards are rotated 180 degrees in the opposite direction to return to the initial position to turn over the next PCB board. However, the process of flipping the fixture back and forth takes a long time, resulting in low efficiency and difficulty in achieving the purpose of continuous operation. Utility Model Content

[0004] The utility model aims to provide a PCB board transfer platform which can realize fast and efficient turning over of the PCB board.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A PCB board transfer platform includes two vertical uprights arranged along the width direction thereof, a conveyor belt is installed between the two uprights, mounting plates are evenly arranged on the outer surface of the conveyor belt, a fixed clamp is installed on the outer surface of the mounting plate, and a movable clamp is arranged on the outer surface of the mounting plate through an elastic mechanism, and the movable clamp and the fixed clamp are arranged parallel to each other. First wedge blocks are installed on both sides of the upper surface of the movable clamp along the width direction, and both sides of the two uprights along the thickness direction are provided with an extrusion mechanism that can be extruded and matched with the first wedge block. Support seats are provided at the bottom of the two uprights, and the uprights are inserted into the inside of the support seats. A lifting mechanism that can drive the two uprights to rise and fall at the same time is commonly provided inside the two support seats, and the thickness direction is perpendicular to the width direction and the vertical direction.

[0007] It can be seen that the conveyor belt drives multiple mounting plates to perform intermittent rotational motion. When the conveyor belt is aligned with one side of the conveyor line, the movable clamp can be driven to lift up through the setting of the extrusion mechanism and the first wedge block, and then the PCB board on the conveyor line can be sent between the movable clamp and the fixed clamp, and then the PCB is clamped and fixed by the elastic mechanism. When the PCB board rotates 180 degrees to correspond to the conveyor line on the other side, the extrusion mechanism drives the movable clamp to open, and the PCB board is placed on the conveyor line on the other side for transportation, thereby completing the purpose of turning over the PCB board, and this transfer platform can turn over multiple PCB boards at the same time, and the interval time between two adjacent PCB boards is short, so the purpose of continuous and efficient operation can be achieved, and the work efficiency can be improved. Through the setting of the lifting mechanism, the height of the transfer platform can be adjusted, which is convenient for use with conveyor lines of different heights. The overall size of the scheme in the thickness direction is small, and multiple PCBs are lifted, effectively utilizing the height space to reduce the floor space.

[0008] Furthermore, the elastic mechanism includes two sliding grooves opened on the outer surface of the mounting plate, two sliders are installed on the side of the movable splint facing the mounting plate, and the sliders are arranged in the sliding grooves, a sliding rod is vertically installed inside the sliding grooves, and the sliders are slidably installed on the outer surface of the sliding rod, and a spring is sleeved on the outer surface of the sliding rod, and the two ends of the spring are respectively abutted against the top wall of the sliding groove and the slider.

[0009] When the conveyor belt drives the conveyor belt to align with one side of the conveyor line, the conveyor belt stops moving, and then the first wedge block is squeezed by the squeezing mechanism, thereby driving the first wedge block to move away from the fixed clamping plate, and driving the slider to slide on the slide rod to compress the spring. As the conveyor line drives the PCB board to be inserted between the fixed clamping plate and the movable clamping plate, the squeezing mechanism cancels the squeezing of the first wedge block. At this time, the compressed spring pushes the slider to move, and then drives the movable clamping plate to move back toward the fixed clamping plate, thereby achieving the purpose of clamping and fixing the PCB board, so that the PCB board remains stable during the rotation process.

[0010] Furthermore, the extrusion mechanism includes a fixed sleeve installed on the outer surface of the vertical plate, an electric push rod is installed inside the fixed sleeve, a second wedge block is installed at the end of the telescopic end of the electric push rod, and the second wedge block is extruded and matched with the first wedge block.

[0011] By starting the electric push rod to drive its telescopic end to extend outward, the second wedge block can be driven to squeeze the first wedge block, driving the first wedge block to move away from the fixed clamping plate. At this time, the fixed clamping plate and the movable clamping plate remain in an open state, so that the PCB board can enter between the two, and then the PCB board is clamped and fixed under the action of the elastic mechanism.

[0012] Furthermore, the lifting mechanism includes bearing seats respectively installed inside the two support seats, a threaded rod is sleeved inside the bearing seat, a threaded hole is opened at the bottom of the vertical plate, and the upper end of the threaded rod is arranged in the threaded hole, a motor is installed on the outer surface of one side of the support seat, the end of the motor output shaft is connected to a connecting shaft, and the end of the connecting shaft passes through the interior of the other side support seat and is rotatably connected to its inner wall, a first bevel gear is installed at the bottom of the two threaded rods, two second bevel gears are installed on the outer surface of the connecting shaft, and the second bevel gear is meshed with the first bevel gear.

[0013] By starting the motor, the connecting shaft can be driven to rotate, and then the two second bevel gears on its surface can be driven to rotate. Since the second bevel gear and the first bevel gear are meshed with each other, the two threaded rods can be driven to rotate at the same time. Since the threaded rods and the threaded holes are threadedly connected, the two vertical plates can be driven to rise and fall at the same time, and the height of the transfer platform can be adjusted, so that it can be used in conjunction with conveyor lines of different heights.

[0014] Furthermore, a sleeve is connected between the two support seats, and the sleeve is sleeved on the outer surface of the connecting shaft.

[0015] By setting the sleeve, the connecting shaft can be hidden inside it, avoiding the situation where the connecting shaft is damaged or deformed due to collision, thereby increasing its service life.

[0016] Furthermore, both inner walls of the support seat are provided with limiting grooves, limiting blocks are arranged inside the limiting grooves, and the ends of the limiting blocks are connected to the outer surface of the conveyor belt.

[0017] By setting the limit groove and the limit block, the rising height of the conveyor belt can be limited to prevent it from falling off from the inside of the support seat and causing overturning. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a PCB board transfer platform comprises two vertical upright plates 100 arranged along the width direction thereof, a conveyor belt 101 is installed between the two upright plates 100, mounting plates 102 are evenly arranged on the outer surface of the conveyor belt 101, a fixed clamping plate 103 is installed on the outer surface of the mounting plate 102, a movable clamping plate 104 is arranged on the outer surface of the mounting plate 102 through an elastic mechanism 200, and the movable clamping plate 104 and the fixed clamping plate 103 are arranged parallel to each other. First wedge blocks 105 are installed on both sides of the upper surface of the movable clamping plate 104 along the width direction, and a pressing mechanism 300 capable of pressing and cooperating with the first wedge block 105 is arranged on both sides of the two upright plates 100 along the thickness direction. Support seats 106 are arranged at the bottom of the two upright plates 100, and the upright plates 100 are inserted inside the support seats 106, and a lifting mechanism 400 capable of driving the two upright plates 100 to rise and fall at the same time is arranged inside the two support seats 106. The thickness direction is perpendicular to the width direction and the vertical direction.

[0026] When in use, the transfer platform is first placed between the first positions of the two conveyor lines, and the transfer platform is adjusted to a suitable height by the lifting mechanism 400. The conveyor belt 101 drives the mounting plate 102 on its surface to rotate intermittently, and then the PCB board is transported by the front conveyor line. At this time, the first wedge block 105 is squeezed by the squeezing mechanism 300, and then the first wedge block 105 drives the movable clamping plate 104 to move away from the fixed clamping plate 103, so that the movable clamping plate 104 and the fixed clamping plate 103 are kept in an open state, and the front conveyor line transports the PCB board to between the movable clamping plate 104 and the fixed clamping plate 103, and then the squeezing mechanism 300 cancels the squeezing of the first wedge block 105, and under the action of the elastic mechanism 200, The movable clamping plate 104 is driven to move toward the fixed clamping plate 103 again, and the PCB board is clamped and fixed between it and the fixed clamping plate 103. Then the conveyor belt 101 drives the PCB board to rotate intermittently. During this process, the subsequent PCB board enters between other fixed clamping plates 103 and the movable clamping plate 104 and is clamped and fixed. When the PCB board rotates 180 degrees to correspond to the conveying line on the other side, the squeezing mechanism 300 drives the movable clamping plate 104 to open, and the PCB board is placed on the conveying line on the other side for transportation, thereby completing the purpose of turning over the PCB board. Since the transfer platform can turn over multiple PCB boards at the same time, and the interval time between two adjacent PCB boards is short, it can achieve the purpose of continuous and efficient operation, thereby improving the operation efficiency.

[0027] Specifically, the elastic mechanism 200 includes two slide grooves 201 provided on the outer surface of the mounting plate 102, two sliders 202 are installed on the side of the movable clamping plate 104 facing the mounting plate 102, and the sliders 202 are arranged in the slide grooves 201, a slide bar 203 is vertically installed inside the slide grooves 201, and the sliders 202 are slidably installed on the outer surface of the slide bar 203, and a spring 204 is sleeved on the outer surface of the slide bar 203, and the two ends of the spring 204 are respectively in contact with the top wall of the slide groove 201 and the slider 202. When the conveyor belt 101 drives the conveyor belt 101 to align with one side of the conveyor line, the conveyor belt 101 stops moving, and then passes through the extruder The mechanism 300 squeezes the first wedge block 105, thereby driving the first wedge block 105 to move away from the fixed clamping plate 103, and drives the slider 202 to slide on the slide bar 203, compressing the spring 204. As the conveyor line drives the PCB board to be inserted between the fixed clamping plate 103 and the movable clamping plate 104, the squeezing mechanism 300 cancels the squeezing of the first wedge block 105. At this time, the compressed spring 204 pushes the slider 202 to move, and then drives the movable clamping plate 104 to move back toward the fixed clamping plate 103, thereby achieving the purpose of clamping and fixing the PCB board, so that the PCB board remains stable during the rotation process.

[0028] Specifically, the squeezing mechanism 300 includes a fixed sleeve 301 installed on the outer surface of the vertical plate 100, an electric push rod 302 is installed inside the fixed sleeve 301, and a second wedge block 303 is installed at the end of the telescopic end of the electric push rod 302, and the second wedge block 303 is squeezed and matched with the first wedge block 105. By starting the electric push rod 302 to drive its telescopic end to extend outward, the second wedge block 303 can be driven to squeeze the first wedge block 105, driving the first wedge block 105 to move away from the fixed clamping plate 103. At this time, the fixed clamping plate 103 and the movable clamping plate 104 remain in an open state, so that the PCB board can enter between the two, and then the PCB board is clamped and fixed under the action of the elastic mechanism 200.
