Description

Technical Field

[0001] This utility model relates to the field of circuit board insertion machine technology, specifically a circuit board insertion device. Background Technology

[0002] An insertion machine is a machine that automatically installs tape-and-reel electronic components onto a printed circuit board according to a program. In the traditional electronics assembly industry, workers mainly rely on manually inserting electronic components onto the circuit board. Since machines began mass production, the shortcomings of manual insertion, such as slow speed and poor process, have been exposed. Using an insertion machine to automatically install electronic components onto the circuit board can save labor costs and improve the insertion process. The operation of an insertion machine basically includes components such as capacitors, inductors, and connectors. The engineers in the design process will divide the insertion parts of each station according to the workload and rationality. Each machine is only responsible for installing a few components and repeating the same operation to minimize the chance of errors.

[0003] Chinese patent CN201821474646.3 discloses a plug-in machine that can be used for inserting various circuit boards. This device drives the slide rails to move via a cylinder, thereby changing the distance between the two slide rails to clamp and fix circuit boards of different sizes, thus enabling the processing of various circuit boards. However, because the circuit boards are thin and brittle, it is difficult to control the clamping force during fixing. Over-clamping can easily cause the circuit board to bend and deform, which not only damages the circuit board but also affects the accuracy of the plug-in positioning, causing positioning deviation and affecting the normal use of the device. In view of the above situation, a technical innovation is made on the basis of the existing circuit board plug-in device. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board insertion device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board insertion device, comprising:

[0006] The insertion machine has two sets of concave plates evenly placed on the top of its machine base, arranged in a mirror-symmetrical pattern. A base plate is provided at the bottom of the inner sidewall of each concave plate. A clamping plate is provided on the opposite side of each base plate. Buffer pads are provided on the top of the base plates and on the opposite sides of the clamping plates. A set of connecting posts is provided on both the left and right sides of each clamping plate. An indicator rod is provided between the two sets of connecting posts, located on the top of the concave plate. A warning strip is printed in red on the top of the concave plate, and the indicator rod corresponds to the warning strip. Two sets of guide rods are evenly arranged on the side of the clamping plate away from the base plate, with springs placed around their outer rings. Two sets of through holes are evenly provided on the opposite sides of each of the two concave plates. The end of the guide rod away from the clamping plate passes through the through hole and is connected to a limiting plate. The spring is positioned between the concave plate and the limiting plate.

[0007] Preferably, the top of the insertion machine is provided with two sets of sliding grooves, and a bidirectional lead screw is provided in the sliding groove. Two sets of internal threaded sliders are evenly screwed to the outer wall of the bidirectional lead screw, and the two sets of concave plates are respectively provided on the top of the two sets of internal threaded sliders.

[0008] Preferably, the top of the insertion machine is provided with a clearance groove, which is located behind the slide groove. Two sets of worm gears are evenly arranged in the clearance groove, and the rear side of the bidirectional lead screw passes through the slide groove and the clearance groove and is connected to the worm gears.

[0009] Preferably, a servo motor is provided on the top of the insertion machine, and a worm gear is provided on the left side of the output end of the servo motor.

[0010] Preferably, the outer ring of the worm gear is uniformly fitted with two sets of bearing seats, and the two sets of bearing seats are evenly arranged on the top of the insertion machine.

[0011] Preferably, the worm is located above the two sets of worm wheels, and the worm meshes with the two sets of worm wheels.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a servo motor to drive two sets of concave plates to move inward synchronously, thereby enabling the clamping plate located inside the concave plates to clamp the circuit board. The buffer pad prevents scratches when the circuit board comes into contact with the base plate and the clamping plate. At the same time, the elasticity of the spring and the buffer pad can provide a cushioning effect when the clamping plate clamps the circuit board. Furthermore, the self-locking property of the worm gear can improve the clamping stability of the clamping plate on the circuit board.

[0014] When the concave plate moves, it will cause the warning strip to move synchronously. When the warning strip is aligned with the indicator rod, it can alert the worker to stop the servo motor, preventing the servo motor from driving the clamping plate to apply excessive clamping force to the circuit board and damaging the circuit board.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4A circuit board insertion device includes an insertion machine 1. Two sets of concave plates 11 are evenly placed on the top of the machine base of the insertion machine 1. The two sets of concave plates 11 are symmetrically distributed front and back. A base plate 23 is slidably disposed on the bottom of the inner sidewall of the concave plates 11. A clamping plate 24 is fixedly disposed on the opposite sides of the two sets of base plates 23. Buffer pads 25 are fixedly disposed on the top of the base plates 23 and on the opposite sides of the two sets of clamping plates 24. A circuit board is placed between the two sets of concave plates 11, with the circuit board positioned on top of the two sets of base plates 23. When the two sets of concave plates 11 move inward, they will cause the two sets of clamping plates 24 to clamp the front and back sides of the circuit board. The buffer pads 25 prevent scratches when the circuit board contacts the base plates 23 and clamping plates 24. A set of connecting posts 2 are fixedly disposed on the left and right sides of the clamping plates 24. An indicator rod 21 is fixedly disposed between the two sets of connecting posts 2. The indicator rod 21 is located on the concave plate 1. At the top of the concave plate 11, a warning strip 22 is printed with red paint. The indicator rod 21 corresponds to the warning strip 22. Two sets of guide rods 26 are evenly fixed on the side of the clamping plate 24 away from the base plate 23. A spring 27 is placed on the outer ring of the guide rod 26. Two sets of through holes are evenly opened on the opposite sides of the two sets of concave plates 11. The end of the guide rod 26 away from the clamping plate 24 passes through the through hole and is connected to the limiting plate 12. When the concave plate 11 drives the base plate 23 and the clamping plate 24 to clamp the circuit board, the base plate 23 and the clamping plate 24 are blocked by the circuit board, causing the concave plate 11 to slide along the guide rod 26 on the outside of the base plate 23 and the clamping plate 24, and pulling the spring 27 to extend. The elasticity of the spring 27 and the buffer pad 25 can make the clamping plate 24 produce a buffering effect when clamping the circuit board. The spring 27 is fixedly set between the concave plate 11 and the limiting plate 12.

[0022] The top of the insertion machine 1 is evenly provided with two sets of sliding grooves. A bidirectional lead screw 17 is rotatably installed in the sliding groove. Two sets of internally threaded sliders 18 are evenly screwed onto the outer wall of the bidirectional lead screw 17. Two sets of concave plates 11 are respectively fixed on the top of the two sets of internally threaded sliders 18. The top of the insertion machine 1 is provided with a clearance groove, which is located behind the sliding groove. Two sets of worm gears 16 are evenly rotatably installed in the clearance groove. The rear side of the bidirectional lead screw 17 passes through the sliding groove and the clearance groove and connects to the worm gears 16. A servo motor 13 is fixedly installed on the top of the insertion machine 1. The output end of the servo motor 13 is fixedly installed on the left side. A worm gear 15 is provided, and two sets of bearing seats 14 are evenly sleeved on the outer ring of the worm gear 15. The two sets of bearing seats 14 are evenly fixed on the top of the insertion machine 1. The bearing seats 14 support the rotation of the worm gear 15. The worm gear 15 is located above the two sets of worm wheels 16 and meshes with the two sets of worm wheels 16. The worm gear 15 is driven to rotate by the servo motor 13. The worm gear 15 drives the worm wheels 16 to rotate. The worm wheels 16 drive the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17 drives the two sets of internal thread sliders 18 to move inward synchronously, which in turn drives the two sets of concave plates 11 to move inward synchronously.

[0023] Working Principle: The insertion machine 1 is a common piece of machinery in the circuit board production process. Its working principle is well-established and will not be elaborated upon here. The servo motor 13 drives the worm gear 15 to rotate, which in turn drives the worm wheel 16. The worm wheel 16 then drives the bidirectional lead screw 17, which in turn drives two sets of internal thread sliders 18 to move inward synchronously. This, in turn, drives two sets of concave plates 11 to move inward synchronously, placing the circuit board between the two sets of concave plates 11 and positioning it on top of the two sets of base plates 23. When the two sets of concave plates 11 move inward, they drive two sets of clamping plates 24 to clamp the front and rear sides of the circuit board. The buffer pad 25 prevents scratches from occurring when the circuit board contacts the base plate 23 and clamping plates 24. When plate 11 drives base plate 23 and clamping plate 24 to clamp the circuit board, the base plate 23 and clamping plate 24 are blocked by the circuit board, causing concave plate 11 to slide along guide rod 26 on the outside of base plate 23 and clamping plate 24, and pulling spring 27 to extend. The elasticity of spring 27 and buffer pad 25 can generate a buffering effect when clamping plate 24 clamps the circuit board. When concave plate 11 slides on the outside of base plate 23 and clamping plate 24, it will drive warning strip 22 to move synchronously. When warning strip 22 is aligned with indicator rod 21, it indicates that clamping plate 24 is located at the innermost side of concave plate 11, thereby warning the worker to stop servo motor 13 to prevent servo motor 13 from driving clamping plate 24 to apply excessive clamping force to circuit board and damage circuit board.
