Description

Technical Field

[0001] The utility model relates to the technical field of SMT measurement, in particular to a horizontal SMT measurement tool. Background Art

[0002] Currently, after the circuit board is mounted, it is generally necessary to use a distance meter to detect it to ensure that the height of the mount meets the specified requirements.

[0003] An SMT measurement tool with publication number CN212041541U includes a stepping conveyor belt and a detection device. The conveying surface of the stepping conveyor belt is evenly equipped with mounting seats. The detection device includes two vertical plates, which are respectively placed on both sides of the stepping conveyor belt. The upper sides of the two vertical plates jointly support and fix the top plate. A first cylinder is installed on the upper side of the top plate. The piston rod of the first cylinder is vertically downwardly arranged and passes through the top plate. The lower end of the piston rod of the first cylinder is fixedly connected to the flat plate. Two or four rangefinders are installed on the lower side of the flat plate. The rangefinder is arranged opposite to the mounting seat. The utility model installs the circuit board in the mounting seat and transmits it through the stepping conveyor belt so that the mounting seat with the circuit board is located below the detection device. The rangefinder measures the distance between the rangefinder and the patch circuit board. When the deviation from the set value is within ±0.3mm, the rangefinder controls the connected alarm, and the rangefinder controls the alarm to sound an alarm, indicating that an unqualified product is encountered.

[0004] Although this device can easily detect unqualified products, it uses a push plate to fix the circuit boards, which requires the user to fix them one by one and remove them one by one after the measurement is completed. This is more troublesome and reduces the user's work efficiency. In addition, the device does not have a cleaning function and cannot clean the surface of the circuit board, resulting in dust or foreign matter remaining on the surface of the circuit board, which in turn affects the normal measurement of the circuit board by the distance meter. In view of this, we propose a horizontal SMT measurement tooling. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] A horizontal SMT measurement tool includes a mounting base 1. A controller is provided at the bottom of the inner wall of the mounting base 1. The controller is connected to a rangefinder 13 and a stepping conveyor belt 11 respectively. The rear surface of the inner wall of the mounting base 1 is fixedly connected to the stepping conveyor belt 11 by bolts, which is used to drive the circuit board on the top of the conveyor belt body to move to the right.

[0027] Specifically, an n-type mounting frame 12 is fixedly connected to the top of the mounting base 1 by bolts, and a distance meter 13 is fixedly connected to the top of the inner wall of the n-type mounting frame 12 by bolts for measuring the height of the patch on the top of the circuit board.

[0028] As a preferred embodiment of this embodiment, an adjustment mechanism 2 is provided above the mounting seat 1. The adjustment mechanism 2 includes an adjustment motor 21. The adjustment motor 21 is fixedly connected to the top of the n-shaped mounting frame 12 by bolts to drive the bidirectional threaded rod 22 to rotate.

[0029] Specifically, the output shaft of the adjusting motor 21 is coaxially connected to the bidirectional threaded rod 22, and the bidirectional threaded rod 22 is symmetrically provided with threads with opposite thread directions near the front and rear sides, so that when the bidirectional threaded rod 22 rotates, the two sliders 24 move in opposite directions. The front end of the bidirectional threaded rod 22 is fixedly connected to the limiting plate 23 by bolts, which is used to limit the position of the slider 24 near the front side.

[0030] Specifically, sliders 24 are symmetrically provided near the front and rear sides of the top of the n-shaped mounting frame 12 . The two sliders 24 are respectively threadedly connected to the bidirectional threaded rod 22 to drive the top plate 25 to move.

[0031] Specifically, the tops of the two sliders 24 are respectively fixedly connected to the top plates 25 by bolts, which are used to drive the connecting plate 26 to move, and the bottoms of the two top plates 25 are respectively fixedly connected to the connecting plates 26 by bolts, which are used to drive the mounting plate 27 to move.

[0032] Specifically, the bottoms of the two connecting plates 26 are fixedly connected to the mounting plates 27 by bolts, which are used to drive the mounting frame 28 to move. One end of the two mounting plates 27 passes through the front and rear ends of the n-type mounting frame 12 and is fixedly connected to the mounting frame 28 by bolts, which is used to drive the limiting rotating rod 29 to move.

[0033] Specifically, a plurality of limiting rotating rods 29 are rotatably connected to the top of the inner wall of the mounting frame 28 via bearings. The limiting rotating rods 29 are evenly arranged at equal intervals to limit the position of the circuit board.

[0034] Furthermore, a plurality of cleaning mechanisms 3 are provided at a position near the left side of the top of the mounting frame 28. The cleaning mechanisms 3 are arranged evenly and equidistantly. The cleaning mechanisms 3 include a powerful fan 31. The powerful fan 31 and the top of the mounting frame 28 corresponding to its position are fixedly connected by bolts. The powerful fan 31 inhales external air through the air intake pipe 32, and then sends the air into the nozzle 34 through the air intake pipe 32. Finally, the nozzle 34 sprays the air toward the top of the circuit board.

[0035] It should be added that the air inlet of the powerful fan 31 is connected to the air inlet pipe 32, the air outlet of the powerful fan 31 is connected to the air outlet pipe 33, one end of the air outlet pipe 33 is connected to the nozzle 34, and the nozzle 34 and the air outlet pipe 33 are connected to each other.

[0036] It is worth mentioning that the structures and working principles of the stepping conveyor belt 11 and the powerful fan 31 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0037] During specific use, the user first arranges the circuit boards in a row and places them on the top of the stepping conveyor belt 11, and turns on the adjustment motor 21. The adjustment motor 21 drives the bidirectional threaded rod 22 to rotate, thereby driving the two sliders 24 to move in the direction close to the mounting seat 1, thereby driving the two top plates 25 to move in the direction close to the mounting seat 1, thereby driving the two connecting plates 26 to move in the direction close to the mounting seat 1, thereby driving the two mounting plates 27 to move in the direction close to the mounting seat 1, thereby driving the two mounting brackets 28 to move in the direction close to the mounting seat 1, thereby driving all the limit rotating rods 29 to move in the direction close to the mounting seat 1;

[0038] Until the front and rear ends of the circuit board are in contact with the outer circumference of the limit rotating rod 29 corresponding to their positions, the position of the circuit board in the Y-axis direction is fixed, the stepping conveyor 11 and the rangefinder 13 are turned on, the stepping conveyor 11 drives all the circuit boards to move to the right, and all the powerful fans 31 are turned on. The powerful fans 31 draw in external air through the air inlet pipes 32, and then send the air into the nozzles 34 through the air inlet pipes 32. Finally, the nozzles 34 spray the air onto the top of the circuit board corresponding to its position, cleaning away the dust or foreign matter remaining on the surface of the circuit board;

[0039] When the circuit board moves to the position directly below the distance meter 13, the distance meter 13 detects the circuit board. If the circuit board fails to meet the standards, the distance meter 13 sends a signal to the controller, which controls the stepping conveyor belt 11 to be closed, and the user can remove the circuit board directly below the distance meter 13.

[0040] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
