Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing equipment technology, and in particular to a magnetic transmission structure for PCB board drying equipment. Background Technology

[0002] In the wet process of printed circuit boards, a drying device is usually used to dry the PCB board surface sequentially. During the transmission process, tiny dust or particles are generated when gear parts come into contact with each other. As the device is used for a long time, the dust or particles will spread. When the dust on the PCB board surface exceeds a certain range, it will have a negative impact on the quality. Although some devices use a non-contact magnetic rotation structure (such as Chinese utility model patent application number CN202322509829.1), the magnetic transmission structure of the drying device is usually installed inside the device for product transportation. This makes the magnetic wheels in the high-temperature drying section of the device susceptible to high temperature, which affects their performance and reduces the service life of the magnetic wheels in that area. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing drying equipment where the magnetic drive structure is typically installed throughout the equipment for product transport. This makes the magnetic wheels in the high-temperature drying section of the equipment susceptible to high temperatures, affecting their performance and reducing their lifespan. Therefore, this invention proposes a magnetic drive structure for PCB board drying equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A magnetic drive structure for a PCB board drying equipment includes a drying equipment body and a conveying device penetrating the drying equipment body. The conveying device includes a magnetic wheel conveying assembly and a roller conveying assembly. A dust cover is installed on the outside of the magnetic wheel conveying assembly. A movable door is provided on the dust cover. An air receiving assembly is installed on the outside of the movable door. The air receiving assembly includes a shell and a filter core assembly. Air outlet assemblies are installed at both ends of the dust cover. A series of powerful blowers and a heating box are installed inside the drying equipment body. The air outlet and air inlet ends of the powerful blowers are equipped with T-joints.

[0006] Furthermore, a replacement port is provided on the side of the outer casing. The opening size of the replacement port is the same as the cross-sectional size of the filter element assembly. A sealing plate is provided outside the replacement port, and a sealing strip is provided between the sealing plate and the replacement port.

[0007] Furthermore, the air inlet end of the outer casing is equipped with a pipe connector, which is connected to a tee connector via a flexible hose. A valve is installed on the flexible hose to regulate the gas flow rate.

[0008] Furthermore, the dust cover has a rectangular structure, and the dust cover is hinged to the movable door for a movable connection.

[0009] Furthermore, the length of the movable door is the same as the long side of the dust cover, and a locking device is provided between the movable door and the dust cover.

[0010] Furthermore, support rods are provided on both sides of the inner wall of the movable door, and exhaust pipes are installed on the support rods. Ventilation holes are equidistantly opened on the surface of the exhaust pipe facing the magnetic wheel conveying assembly.

[0011] Furthermore, the magnetic wheel conveying assembly includes a main drive magnetic wheel and a passive magnetic wheel, with a drive component connected to the main drive magnetic wheel.

[0012] Furthermore, the main drive magnetic wheel and the dust cover are movably connected through the main drive shaft, and the main drive magnetic wheel and the driven magnetic wheel are connected by orthogonal transmission. The driving component includes a drive motor, a drive wheel, and a driven wheel mounted on the main drive shaft.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the air intake component, the air outlet component and the powerful blower work together to continuously divert the gas output by the powerful blower and introduce it into the dust cover for heat dissipation and cooling. The air outlet component then discharges the airflow, which is conducive to quickly and efficiently cooling the magnetic wheel in the high-temperature drying section of the equipment. This avoids the performance and service life of the magnetic wheel being affected by high temperature, and has high practicality.

[0015] 2. In this utility model, by setting the filter core group on the air receiving component, the gas introduced into the dust cover is filtered by the filter core group, which can filter out moisture or small impurities in the gas, avoid excessive humidity or the presence of fine impurities in the gas, thereby affecting the performance and service life of the magnetic wheel, and thus reducing the conveying efficiency of the product, which has high practicality.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-5 A magnetic drive structure for a PCB board drying equipment includes a drying equipment body 1 and a conveying device 13 that passes through the drying equipment body 1. The conveying device 13 includes a magnetic wheel conveying assembly 2 and a roller conveying assembly 4. A dust cover 6 is installed on the outside of the magnetic wheel conveying assembly 2. A movable door 14 is provided on the dust cover 6. An air receiving assembly 7 is installed on the outside of the movable door 14. The air receiving assembly 7 includes a shell 701 and a filter core assembly 702. Air outlet assemblies 8 are installed at both ends of the dust cover 6. A series of high-power blowers 3 and a heating box 5 are installed inside the drying equipment body 1. A three-way connector 10 is installed at both the air outlet and air inlet ends of the high-power blowers 3.

[0025] By adopting the above technical solution, the air intake component 7 and air outlet component 8 on the dust cover 6 cooperate with the powerful blower 3 to circulate the introduced gas within the dust cover 6. This allows for heat dissipation of the magnetic wheel conveying component 2, which is located in the high-temperature drying section of the equipment. Furthermore, the gas circulation accelerates the cooling rate of this area. The filter core group 702 on the air intake component 7 can filter out moisture or minute impurities in the gas, preventing excessive humidity or the presence of minute impurities that could affect the service life of the magnetic wheel. This structural design effectively improves the service life of the magnetic wheel and has high practicality.

[0026] Specifically, the material used to filter moisture from the gas in the filter element assembly 702 is a solid adsorbent. The filter element assembly 702 includes a square box composed of filter screens. The shape of the square box matches the shape of the outer shell 701. A fixed adsorbent is installed inside the square box to adsorb moisture from the air. Through the arrangement of the square box composed of filter screens and the filter element assembly 702 composed of solid adsorbent, moisture or small impurities in the gas passing through can be successfully filtered out, avoiding excessively high gas humidity or the presence of fine impurities adhering to the magnetic wheel and affecting its use.

[0027] The outer casing 701 has a replacement port 703 on its side. The opening size of the replacement port 703 is the same as the cross-sectional size of the filter element assembly 702. A sealing plate is provided outside the replacement port 703, and a sealing strip is provided between the sealing plate and the replacement port 703.

[0028] By adopting the above technical solution, fasteners are provided between the sealing plate and the replacement port 703, which makes it easy to open the sealing plate on the replacement port 703, thereby facilitating the replacement of the internal filter element assembly 702.

[0029] The air inlet end of the housing 701 is equipped with a pipe connector 11, which is connected to the tee connector 10 via a hose 15. A valve is provided on the hose 15 to regulate the gas flow.

[0030] By adopting the above technical solution, the three-way connector 10 is connected to the outer shell 701 of the air receiving component 7, so that the powerful blower 3 can smoothly send strong air into the dust cover 6 to perform heat dissipation and cooling operations on the magnetic wheel conveying component 2, which has high practicality.

[0031] The dust cover 6 has a rectangular structure and is connected to the movable door 14 by a hinge.

[0032] Furthermore, the length of the movable door 14 is the same as the long side of the dust cover 6, and a locking device is provided between the movable door 14 and the dust cover 6.

[0033] Specifically, the locking mechanism on the movable door 14 and the dust cover 6 allows the dust cover 6 to be closed to form a dustproof shell, providing a dustproof function for the magnetic wheel conveying assembly 2. When it is necessary to inspect or replace the magnetic wheel conveying assembly 2, the locking mechanism on the movable door 14 can be operated to open the movable door 14, thereby facilitating the maintenance or repair of the magnetic wheel conveying assembly 2.

[0034] Support rods 12 are provided on both sides of the inner wall of the movable door 14. Exhaust pipes 9 are installed on the support rods 12. Ventilation holes are equidistantly opened on the surface of the exhaust pipes 9 facing the magnetic wheel conveying assembly 2.

[0035] By adopting the above technical solution, the gas filtered by the air intake component 7 is discharged from the vent on the exhaust pipe 9, which cools down the magnetic wheel conveying component 2 inside the dust cover 6, thus improving the service life of the magnetic wheel.

[0036] Furthermore, the magnetic wheel conveying assembly 2 includes a main drive magnetic wheel 201 and a passive magnetic wheel 202, with a drive component 203 connected to the main drive magnetic wheel 201.

[0037] Driven by the drive unit 203, the main drive magnetic wheel 201 drives the passive magnetic wheel 202 to perform transmission, enabling the roller conveyor assembly 4 connected to the passive magnetic wheel 202 to transport products.

[0038] Specifically, the main drive magnetic wheel 201 and the dust cover 6 are movably connected through the main drive shaft. The main drive magnetic wheel 201 and the passive magnetic wheel 202 are orthogonal drives. The drive component 203 includes a drive motor, a drive wheel, and a driven wheel mounted on the main drive shaft.

[0039] Furthermore, the drive wheel and driven wheel are driven by magnetic wheels. The driven wheel and drive wheel mounted on the main drive shaft are in the form of a cone drive. Another cone drive assembly is set at the bottom of the drive wheel. The cone drive assembly includes a main drive wheel, a driven wheel, and a drive shaft. The drive shaft is provided with a gear groove that mates with the gear at the output end of the drive motor, so that the drive motor works and drives the cone drive wheel assembly to drive. The cone drive wheel assembly drives the drive wheel and the driven wheel to drive, so that the main drive magnetic wheel 201 and the driven magnetic wheel 202 perform orthogonal transmission, so that the roller conveyor assembly 4 can transport the product.

[0040] Working Principle: The dust cover 6 on the outside of the magnetic wheel conveyor assembly 2 provides dust protection. Then, the air inlet component 7 on the dust cover 6, in conjunction with the hose 15, connects to the tee connector 10 at the output end of the powerful blower 3. This allows the air output from the powerful blower 3 to be diverted and introduced into the dust cover 6 of the magnetic wheel conveyor assembly 2 in the drying section, thus dissipating heat and preventing the magnetic wheels in the high-temperature drying section from operating at high temperatures for extended periods, which would affect their performance and lifespan. Furthermore, the air inlet component 7... The filter element assembly 702 facilitates the filtration of moisture and impurities from the introduced gas, allowing clean gas to be delivered into the dust cover 6 through the vent of the exhaust pipe 9. This prevents excessively humid gas or gas containing fine impurities from adhering to the magnetic wheel, thus affecting its service life. Furthermore, the air outlet assembly 8 on the dust cover 6, in conjunction with the powerful blower 3, connects the air inlet assembly 7, the air outlet assembly 8, and the air inlet and outlet pipes of the powerful blower 3, forming a gas circulation within the dust cover 6. This facilitates faster cooling of the magnetic wheel conveying assembly 2 and demonstrates high practicality.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
