Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board processing and conveying device. Background Technique

[0002] At present, when the circuit board is moved to the quality inspection department after processing, a conveyor belt is mostly used for conveying. However, on the one hand, the conveyor belt in the prior art has a large contact area with the circuit board, resulting in a great potential hazard of generating static electricity. On the other hand, since there is no restriction on the circuit board on both sides of the conveyor belt, it is easy to cause the circuit board to displace relative to the conveyor belt during movement, resulting in the circuit board falling or colliding with the subsequent circuit boards and being damaged. Therefore, it is necessary to provide a new circuit board processing and conveying device to solve the above technical problems. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a circuit board processing and conveying device, which reduces the contact area between the circuit board and the conveyor belt during conveying, and at the same time provides side protection for the conveyor belt, improving the safety of circuit board transportation.

[0004] The circuit board processing and conveying device provided by the utility model includes a bottom plate, on which there are two L-shaped frames with the same height and the horizontal parts bent towards each other. A conveying component is installed on the L-shaped frame, and the two conveying components form a circuit board conveying structure. The conveying component includes rotating wheels arranged at both ends of the vertical part of the L-shaped frame and an anti-static rubber conveyor belt tensioned by the rotating wheels.

[0005] A driving component for driving the anti-static rubber conveyor belt is arranged on the bottom plate, including a fixed frame located outside the two L-shaped frames and fixed on the bottom plate. A rotating shaft is rotatably arranged on the fixed frame, and a servo motor for driving the rotating shaft. The middle shaft body of the rotating shaft is in a hexagonal rod structure, and two slidably connected mounting seats are sleeved on the hexagonal rod. The top surface of the mounting seat is fixedly connected to the bottom surface of the corresponding L-shaped frame. A driving wheel for tensioning and driving the anti-static rubber conveyor belt is rotatably arranged on the opposite side surfaces of the two mounting seats, and a hexagonal through hole matched with the hexagonal rod is opened at the center of the driving wheel.

[0006] Insert the circuit board between the two L-shaped frames and make the two sides of the circuit board be located above the anti-static rubber conveyor belt. Turn on the servo motor to drive the hexagonal rod on the rotating shaft to rotate. Since the driving wheel is provided with a hexagonal through hole that matches the hexagonal rod, the driving wheel can drive the anti-static rubber conveyor belt to transmit, so the circuit board can be transmitted along the L-shaped frame. Since only two sides of the circuit board are carried on the two anti-static rubber conveyor belts, the contact area between the circuit board and the conveyor belt is reduced during transportation, and the hidden danger of static electricity generated by the circuit board itself due to friction during transportation is reduced. At the same time, the anti-static rubber conveyor belt further reduces the static electricity generated during transportation of the circuit board, effectively protecting the circuit board. At the same time, the vertical parts of the two L-shaped frames can limit the displacement path of the circuit board and prevent the circuit board from deviating sideways.

[0007] Preferably, guide wheels are installed on the inner walls of the L-shaped frame on both sides of the driving wheel to abut against the anti-static rubber conveyor belt, and the connecting line between the guide wheel and the wheel center of the driving wheel is a triangular structure. The guide wheel can provide re-tensioning to ensure the transmission effect of the driving wheel on the anti-static rubber conveyor belt.

[0008] Preferably, the base plate is further provided with a distance adjustment component for adjusting the distance between the two L-shaped frames, comprising two threaded rods arranged at the same height, the threaded rods being rotatably arranged on a frame at the end of the base plate, gears being fixedly installed on the rod heads on the same side of the two threaded rods, and the two gears and chains form a sprocket transmission structure, and a driving motor is fixedly installed on one frame, and the output end of the driving motor is drivingly connected to the corresponding threaded rod;

[0009] The two ends of the threaded rod are respectively screwed with the screw holes of the connecting seat through threaded sections with opposite rotation directions, and the two connecting seats on the threaded rod are respectively fixedly installed on the two groups of L-shaped frames.

[0010] The distance between the two L-shaped frames can be flexibly adjusted according to the width of the circuit board: the drive motor is turned on to drive the threaded rod connected to it to rotate. Since the two threaded rods are connected by gears and chains, the two threaded rods rotate synchronously, and the threaded rods drive the connecting seat through the threaded sections with opposite rotation directions and drive the two L-shaped frames to slide towards or away from each other.

[0011] Since the two mounting seats on the hexagonal rod are respectively fixedly installed at the bottom of the two sets of L-shaped frames, when the two sets of L-shaped frames slide toward or away from each other, the mounting seats can drive the driving wheel to slide axially along the hexagonal rod, so that the transmission of the anti-static rubber conveyor belt is not affected when the spacing between the two sets of L-shaped frames is adjusted.

[0012] Preferably, two groups of symmetrically distributed ion blowers are installed on the bottom plate, and the air outlets of the ion blowers are arranged obliquely upward. When the circuit board is being transported, turn on the ion blowers and direct them at the circuit board. The ion blowers can generate positive and negative ions to neutralize the static charges on the surface of the circuit board, effectively eliminating static electricity.

[0013] Preferably, a shielding component is arranged between the two L-shaped frames. The shielding component includes a gantry fixing frame which is fixedly installed at one end of the two L-shaped frames. One end of an elastic corrugated shielding sleeve is connected to the inner wall of the gantry fixing frame, and a gantry sliding frame is fixedly installed at the other end of the elastic corrugated shielding sleeve. A T-shaped slider is fixedly installed at the bottom of the gantry sliding frame and is inserted into and slidably connected to a T-shaped chute opened on the upper surface of the L-shaped frame. Before the circuit board is transported, pull the gantry sliding frame along the L-shaped frame to stretch the elastic corrugated shielding sleeve and cover it above the two L-shaped frames. On the one hand, the elastic corrugated shielding sleeve can block dust and prevent it from falling onto the circuit board. On the other hand, the elastic corrugated shielding sleeve can prevent strong electromagnetic fields from interfering with the circuit board and affecting its subsequent performance.

[0020] Please refer to Figures 1 to 4, a circuit board processing and conveying device, including a bottom plate 1, on which there are two L-shaped frames 2 with equal height and horizontal parts bent towards each other. A shielding component 7 is arranged between the two L-shaped frames 2, and the shielding component 7 includes a gantry fixing frame 71. The gantry fixing frame 71 is fixedly installed at one end of the two L-shaped frames 2, and one end of an elastic corrugated shielding sleeve 72 is connected to the inner wall of the gantry fixing frame 71. The other end of the elastic corrugated shielding sleeve 72 is fixedly installed with a gantry sliding frame 73, and a T-shaped slider 731 is fixedly installed at the bottom of the gantry sliding frame 73. The T-shaped slider 731 is inserted into a T-shaped chute opened on the upper surface of the L-shaped frame 2 and is slidably connected to the T-shaped chute.

[0021] A conveying component 4 is installed on the L-shaped frame 2, and the two conveying components 4 form a circuit board conveying structure. The conveying component 4 includes rotating wheels 41 arranged at both ends of the vertical part of the L-shaped frame 2 and an anti-static rubber conveyor belt 42 tensioned by the rotating wheels 41. A driving component 5 for driving the anti-static rubber conveyor belt 42 is arranged on the bottom plate 1, including a fixing frame 51 located outside the two L-shaped frames 2 and fixedly installed on the bottom plate 1. A rotating shaft 52 is rotatably arranged on the fixing frame 51, and a servo motor 53 for driving the rotating shaft 52. The middle shaft body of the rotating shaft 52 is in the structure of a hexagonal rod 54, and two slidably connected mounting seats 55 are sleeved on the hexagonal rod 54. The top surface of the mounting seat 55 is fixedly connected to the bottom surface of the corresponding L-shaped frame 2. Driving wheels 56 for tensioning and driving the anti-static rubber conveyor belt 42 are rotatably arranged on the opposite side surfaces of the two mounting seats 55, and a hexagonal through hole matching the hexagonal rod 54 is opened at the center of the driving wheel 56. Guide wheels 43 abutted against the anti-static rubber conveyor belt 42 are installed on the inner walls of the L-shaped frames 2 on both sides of the driving wheel 56, and the guide wheels 43 and the driving wheel 56 form a triangular structure.

[0022] A distance adjusting component 3 for adjusting the distance between the two L-shaped frames 2 is also arranged on the bottom plate 1, including two equal-height threaded rods 31. The threaded rods 31 are rotatably arranged on the frames at the ends of the bottom plate 1. Gear 32 is fixedly installed on the same-side rod heads of the two threaded rods 31, and the two gears 32 and a chain 33 form a sprocket transmission structure. A driving motor 34 is fixedly installed on one frame, and the output end of the driving motor 34 is in transmission connection with the corresponding threaded rod 31. The two ends of the threaded rod 31 are respectively screwed into the threaded holes of the connecting seats 21 through threaded sections with opposite thread directions, and the two connecting seats 21 on the threaded rod 31 are respectively fixedly installed on the two groups of L-shaped frames 2.

[0023] Two groups of symmetrically distributed ion blowers 6 are installed on the bottom plate 1, and the air outlets of the ion blowers 6 are arranged obliquely upward.

[0024] The working principle of the present utility model is as follows:

[0025] The spacing between the two groups of L-shaped frames 2 is flexibly adjusted according to the width of the circuit board. The driving motor 34 is turned on to drive the threaded rod 31 connected thereto to rotate. Since the two threaded rods 31 are connected through the gear 32 and the chain 33, the two threaded rods 31 rotate synchronously, and the threaded rod 31 drives the connecting seat 21 through the threaded sections with opposite rotation directions and drives the two L-shaped frames 2 to slide toward or away from each other. Since the two mounting seats 55 on the hexagonal rod 54 are respectively fixedly installed at the bottom of the two groups of L-shaped frames 2, when the two groups of L-shaped frames 2 slide toward or away from each other, the mounting seats 55 can drive the driving wheel 56 to slide axially along the hexagonal rod 54, so that the transmission of the anti-static rubber conveyor belt 42 is not affected when the spacing between the two groups of L-shaped frames 2 is adjusted.

[0026] Insert the circuit board between the two L-shaped frames 2 so that the two sides of the circuit board are located above the antistatic rubber conveyor belt 42, turn on the servo motor 53 to drive the hexagonal rod 54 on the rotating shaft 52 to rotate, and since the driving wheel 56 is provided with a hexagonal through hole that matches the hexagonal rod 54, the driving wheel 56 can drive the antistatic rubber conveyor belt 42 to transmit, so the circuit board can be transmitted along the L-shaped frame 2. Since only two sides of the circuit board are carried on the two antistatic rubber conveyor belts 42, the contact area between the circuit board and the conveyor belt is reduced during transportation, and the hidden danger of static electricity generated by the circuit board itself due to friction during transportation is reduced. At the same time, the antistatic rubber conveyor belt 42 further reduces the static electricity generated during transportation of the circuit board, effectively protecting the circuit board. At the same time, the vertical parts of the two L-shaped frames 2 can limit the displacement path of the circuit board and prevent the circuit board from skewing sideways.

[0027] Before the circuit board is transported, the gantry sliding frame 73 is pulled outward along the L-shaped frame 2 so that the elastic pleated shielding sleeve 72 is stretched and covered above the two groups of L-shaped frames 2. On the one hand, the elastic pleated shielding sleeve 72 can block dust and prevent dust from falling onto the circuit board. On the other hand, the elastic pleated shielding sleeve 72 can prevent strong electromagnetic fields from interfering with the circuit board.
