A magnetically driven interleaved roller conveyor for printed circuit boards

Abstract

This utility model discloses a magnetically driven interlaced roller conveyor for printed circuit boards, relating to the field of printed circuit board manufacturing equipment technology. It includes two sets of interlaced conveyor assemblies, each consisting of a main drive assembly and three slave drive assemblies. Power transmission between the main and slave drive assemblies is achieved through magnetic coupling. In the main drive assembly, a motor drives the main magnetic ring to rotate, which in turn drives the main drive shaft, slave drive shaft, and end drive shaft to rotate sequentially via multiple magnetic transmission pairs, enabling the main drive roller and end drive roller to work collaboratively. The interlaced rollers of the two conveyor assemblies form a conveying surface, enabling stable conveying and vertical lifting of the printed circuit board. This device uses magnetic drive instead of traditional belt drive, eliminating the problem of belt aging, shedding, and contamination. It has a simple and reliable structure, facilitating the development of refined printed circuit board circuitry.

Description

Technical Field

[0001] This utility model relates to the field of printed circuit board manufacturing equipment technology, specifically a magnetically driven interlaced roller conveyor for printed circuit boards. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), horizontal production lines need to transfer PCBs between different process units, with vertical lifting being a common transfer requirement. Currently, devices that achieve vertical lifting mainly include direct gripping devices, fully accepting conveyor systems, and staggered accepting conveyor systems.

[0003] Interleaved conveyor systems are widely used in various dry and wet processes due to their high efficiency and compact structure. However, traditional interleaved conveyor systems mostly use belt drives, with the belts in direct contact with the printed circuit boards (PCBs). Over long-term use, the belts are prone to aging and shedding, leading to PCB contamination. This not only increases the difficulty of debris control on the production floor but also hinders the development of PCBs towards finer circuitry, hindering cost reduction and product quality improvement. Therefore, those skilled in the art have proposed a magnetically driven interleaved roller conveyor system for PCBs to address the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetically driven interleaved roller conveyor for printed circuit boards to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A magnetically driven interleaved roller conveying device for printed circuit boards includes two sets of interleaved conveying assemblies. Each conveying assembly includes a main drive assembly and three sets of slave drive assemblies. The main drive assembly and the slave drive assemblies achieve power transmission through magnetic coupling. The slave drive main magnetic ring of the main drive assembly and the slave drive slave magnetic ring of the slave drive assembly achieve synchronous rotation through magnetic field coupling, thereby driving the slave drive shaft and the end drive roller. The main drive roller of the main drive assembly and the end drive roller of the slave drive assembly are arranged alternately to jointly form the conveying surface of the printed circuit board, so as to achieve stable conveying and vertical lifting motion.

[0007] As a further embodiment of this utility model: the main drive assembly includes a base plate, a motor, a motor mounting base, a main drive magnetic ring, a main drive shaft, a main drive bearing, a main drive shaft retainer, and a fixing plate. The motor is fixedly connected to the base plate via the motor mounting base. The main drive magnetic ring is fixedly connected to the drive shaft of the motor. The main drive shaft is rotatably connected to the fixing plate via the main drive bearing and passes through the main drive shaft retainer. One end of the main drive shaft retainer is fixed to the base plate.

[0008] As a further embodiment of this utility model, the main drive assembly also includes a main drive slave magnetic ring, a main drive roller, and a slave drive main magnetic ring, all of which are fixedly connected to the main drive shaft.

[0009] As a further embodiment of this utility model: the driven assembly includes a base, side plates, a driven shaft retainer, a driven shaft, an end drive main magnetic ring, an end drive driven slave magnetic ring, an end drive roller, an end drive shaft, an end drive shaft retainer plate, and a driven slave magnetic ring. The base has side plates fixedly connected to both sides, and one end of the base is fixedly connected to the base plate. The driven shaft is fixedly connected to the base through the driven shaft retainer.

[0010] As a further embodiment of this utility model: both the driven magnetic ring and the end driven main magnetic ring are fixedly connected to the driven shaft; both the end driven roller and the end driven magnetic ring are fixedly connected to the end driven shaft, and the two ends of the end driven shaft are fixedly connected to the side plate through the end driven shaft retaining plate.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This device uses magnetic drive to achieve roller conveying, completely replacing the traditional belt drive method, avoiding the problem of printed circuit board contamination caused by belt aging and shedding, and thus improving product quality. Furthermore, power transmission is achieved through the magnetic field of the magnetic ring, reducing mechanical contact wear, lowering the device's failure rate, and extending its service life. The two staggered conveyor assemblies of this device can flexibly achieve vertical lifting, moving away, and moving closer, adapting to the conveying needs of printed circuit boards between different process units. While reducing contamination, it also reduces interference with the printed circuit board circuitry, providing equipment support for the development of printed circuit boards towards finer circuitry and helping to reduce manufacturing costs.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1-3A magnetically driven interleaved roller conveyor for printed circuit boards includes two sets of interleaved conveyor assemblies. Each conveyor assembly includes a main drive assembly and three sets of slave drive assemblies. The main drive assembly and the slave drive assemblies transmit power through magnetic coupling. The slave drive main magnetic ring 108 of the main drive assembly and the slave drive slave magnetic ring 209 of the slave drive assembly rotate synchronously through magnetic field coupling, thereby driving the slave drive shaft 203 and the end drive roller 206. The main drive roller 109 of the main drive assembly and the end drive roller 206 of the slave drive assembly are arranged interleaved to form the conveying surface of the printed circuit board, so as to achieve stable conveying and vertical lifting motion.

[0021] The main drive assembly includes a base plate 100, a motor 101, a motor mounting base 102, a main drive magnetic ring 103, a main drive shaft 105, a main drive bearing 106, a main drive shaft retainer 107, and a mounting plate 110. The motor 101 is fixedly connected to the base plate 100 via the motor mounting base 102. The main drive magnetic ring 103 is fixedly connected to the drive shaft of the motor 101. The main drive shaft 105 is rotatably connected to the mounting plate 110 via the main drive bearing 106 and passes through the main drive shaft retainer 107. One end of the main drive shaft retainer 107 is fixed to the base plate 100.

[0022] The main drive assembly also includes a main drive slave magnetic ring 104, a main drive roller 109, and a slave drive main magnetic ring 108, all of which are fixedly connected to the main drive shaft 105.

[0023] The device is powered by a motor 101 in the main drive assembly, which is securely mounted on the base plate 100 via a motor mounting bracket 102. When the motor 101 starts, its drive shaft drives the main drive magnetic ring 103, which is fixedly connected to it, to rotate synchronously. The main drive magnetic ring 103 and the main drive driven magnetic ring 104 mounted on the main drive shaft 105 form a magnetic coupling relationship. Under the action of the magnetic field, the main drive driven magnetic ring 104 rotates synchronously with the main drive magnetic ring 103, thereby driving the main drive shaft 105 to rotate. The main drive shaft 105 is mounted on the fixed plate 110 via a main drive bearing 106 and passes through a main drive shaft retainer 107. The main drive shaft retainer 107 supports and positions the main drive shaft 105, ensuring its stable rotation.

[0024] The driven assembly includes a base 200, side plates 201, a driven shaft retainer 202, a driven shaft 203, an end drive master magnetic ring 204, an end drive slave magnetic ring 205, an end drive roller 206, an end drive shaft 207, an end drive shaft retainer 208, and a driven slave magnetic ring 209. The side plates 201 are fixedly connected to both sides of the base 200, and one end of the base 200 is fixedly connected to the base plate 100. The driven shaft 203 is fixedly connected to the base 200 through the driven shaft retainer 202.

[0025] The drive magnetic ring 209 and the end drive main magnetic ring 204 are both fixedly connected to the drive shaft 203; the end drive roller 206 and the end drive magnetic ring 205 are both fixedly connected to the end drive shaft 207, and the two ends of the end drive shaft 207 are fixedly connected to the side plate 201 through the end drive shaft retaining plate 208.

[0026] A driven main magnetic ring 108 fixedly mounted on the main drive shaft 105 and a driven slave magnetic ring 209 on the driven drive shaft 203 in the driven drive assembly form a first magnetic transmission pair. When the main drive shaft 105 rotates, the driven main magnetic ring 108 rotates accordingly. Under the action of magnetic field coupling, the driven slave magnetic ring 209 rotates synchronously, thereby driving the driven shaft 203 to rotate. The driven shaft 203 is mounted on the base 200 through a driven shaft retainer 202, ensuring stability during rotation. An end drive main magnetic ring 204 is also fixedly mounted on the driven shaft 203, which forms a second magnetic transmission pair with the end drive slave magnetic ring 205 on the end drive shaft 207. As the driven shaft 203 rotates, the end drive main magnetic ring 204 drives the end drive slave magnetic ring 205 to rotate synchronously, thereby driving the end drive shaft 207 to rotate. The two ends of the end drive shaft 207 are fixedly connected to the side plate 201 through the end drive shaft retaining plate 208. The side plate 201 is installed on both sides of the base 200, which together provide stable support for the end drive shaft 207.

[0027] The main drive roller 109 mounted on the main drive shaft 105 rotates together with the main drive shaft 105, and the end drive roller 206 mounted on the end drive shaft 207 rotates together with the end drive shaft 207. Since the main drive roller 109 of the main drive assembly and the end drive roller 206 of the driven assembly are arranged in an alternating manner, they together form the conveying surface of the printed circuit board. When the printed circuit board is placed on the conveying surface, the rotating main drive roller 109 and the end drive roller 206 drive the printed circuit board forward through friction, achieving stable conveying. Simultaneously, since the device includes two sets of alternating conveying assemblies, by controlling the relative position changes of the two sets of conveying assemblies, the vertical lifting motion of the printed circuit board can be achieved, meeting the conveying requirements between different process units.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
