Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board conveying device that prevents it from falling. Background Technology

[0002] In the processing flow of circuit boards, the conveying equipment is a key link, undertaking the important task of accurately transporting the circuit boards to each processing station, and is an important support for ensuring the efficient and orderly progress of the processing procedures.

[0003] However, current technologies generally use ordinary conveyor belts as the conveying tool, which has significant drawbacks. Because ordinary conveyor belts are not very effective at securing circuit boards, circuit boards are prone to shifting or even falling off the conveyor belt during transport. This not only leads to damage to the circuit boards and economic losses, but may also affect the normal operation of subsequent processing steps. Utility Model Content

The adjusting component is provided with a limiting component for limiting the circuit board. The adjusting component adjusts the limiting component. The adjusting component is provided with a conveying component for conveying the circuit board.

[0006] Preferably, the adjustment assembly includes a fixed base, a guide rod, a mounting base, a double-acting screw, a geared motor, and a mounting plate. Fixed bases are symmetrically fixed to the front and rear sides of the top of the platform. Guide rods are fixedly connected between two adjacent fixed bases.

[0007] Preferably, the limiting assembly includes a rotating shaft, a connecting rod, a pulley, a servo motor, and a conveyor belt. The front and rear sides of the two mounting plates are rotatably connected to the rotating shafts, and the two adjacent rotating shafts are slidably connected to the connecting rod.

Detailed Implementation

[0016] 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.

[0017] Example: A circuit board conveying device to prevent falling, such as Figures 1-3As shown, it includes a bracket 1, a table panel 2, an adjustment component, a limiting component, and a conveying component. The table panel 2 is welded and fixed between the tops of the two brackets 1. An adjustment component is provided on the top of the table panel 2. The adjustment component is provided with a limiting component for limiting the circuit board. The adjustment component adjusts the limiting component. The adjustment component is provided with a conveying component for conveying the circuit board.

[0018] like Figure 1 and Figure 2 As shown, the adjustment assembly includes a fixed base 31, a guide rod 32, a mounting base 33, a double-acting screw 34, a geared motor 35, and a mounting plate 40. Fixed bases 31 are symmetrically welded and fixed on both the front and rear sides of the top of the platform 2. Guide rods 32 are welded and fixed between adjacent fixed bases 31. Mounting bases 33 are symmetrically welded and fixed in the middle of the top of the platform 2. A double-acting screw 34 is rotatably connected between the two mounting bases 33. A geared motor 35 is bolted to the right side of the platform 2. The output shaft end of the geared motor 35 is fixedly connected to the right end of the double-acting screw 34. Two mounting plates 40 are slidably arranged between the two guide rods 32. The double-acting screw 34 passes through the two mounting plates 40 and is threaded to both. When the double-acting screw 34 rotates, it can drive the two mounting plates 40 to move closer or further apart.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the limiting assembly includes a rotating shaft 41, a connecting rod 42, a pulley 43, a servo motor 44, and a conveyor belt 45. The rotating shaft 41 is rotatably connected to the front and rear sides of the two mounting plates 40. The connecting rod 42 is slidably connected between two adjacent rotating shafts 41. The connecting rod 42 is made of high-strength steel and can withstand large torque. The pulley 43 is fixed to the rotating shaft 41 by bolts. The conveyor belt 45 is sleeved between two pulleys 43 adjacent to the same mounting plate 40. The servo motor 44 is bolted to the front of the right mounting plate 40. The output shaft end of the servo motor 44 is fixedly connected to the right end of the adjacent rotating shaft 41. Multiple square openings 46 are spaced apart on the side of the two conveyor belts 45 that are close to each other.

[0020] like Figure 1 As shown, the conveying assembly includes a mounting frame 52 and an electric conveying roller 53. Mounting frames 52 are welded and fixed on both the left and right sides of the top of the platform 2. Multiple electric conveying rollers 53 are spaced apart between the upper parts of the two mounting frames 52. The upper sides of the two mounting plates 40 are provided with strip-shaped openings 51. The electric conveying rollers 53 can pass through the two strip-shaped openings 51. The electric conveying rollers 53 are in contact with the conveyor belt 45. The conveying speed of the electric conveying rollers 53 is the same as the conveying speed of the conveyor belt 45.

[0021] In use, the operator first starts the servo motor 44 and the electric conveyor roller 53. The servo motor 44 drives the connected shaft 41 to start rotating. The shaft 41 drives the other shaft 41 to rotate synchronously through the connecting rod 42, thereby making the two conveyor belts 45 run synchronously. The operator places the circuit board on the electric conveyor roller 53 and ensures that the circuit board is located between the adjacent square openings 46 of the two conveyor belts 45, thereby limiting the circuit board and effectively preventing it from falling during the conveying process. When different models of circuit boards need to be conveyed, the operator starts the reduction motor 35. The reduction motor 35 drives the bidirectional lead screw 34 to rotate, causing the two mounting plates 40 to move closer or further apart under the guidance of the guide rod 32, thereby adjusting the distance between the two conveyor belts 45 to meet the limiting requirements of different models of circuit boards.

[0022] like Figure 3 As shown, it also includes a return spring 6, and a return spring 6 is connected between the connecting rod 42 and the adjacent rotating shaft 41.

[0023] By setting a return spring 6, when two adjacent rotating shafts 41 approach each other during the adjustment of the spacing of the mounting plates 40, the return spring 6 connected to the same connecting rod 42 will be compressed simultaneously, so that the connecting rod 42 can be kept in the middle of the two rotating shafts 41, thereby ensuring the stability of the connecting rod 42.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
