Description

Technical Field

[0001] This utility model relates to the field of antenna spraying and curing technology, and in particular to an antenna spraying and curing device. Background Technology

[0002] Antenna coating and curing is a key process to ensure antenna performance and durability. The core is to first uniformly cover the surface of the antenna substrate (such as metal, plastic, etc.) with a functional coating (commonly including anti-corrosion coating, conductive coating, insulating coating, etc.) using spraying technology, and then use a specific curing method (such as hot air curing, ultraviolet curing, infrared curing, etc.) to cause physical or chemical changes in the resin, curing agent and other components in the coating, transforming them from a liquid or semi-liquid state to a stable solid state, and finally forming a protective layer or functional layer with strong adhesion, dense structure and qualified performance on the antenna surface.

[0003] Existing airflow delivery methods are often relatively simple and may not be able to accurately direct airflow to all corners inside the enclosure, resulting in uneven air circulation. This causes inconsistent heating of different parts of the antenna, and some areas may not cure completely, affecting the overall performance of the antenna. In terms of air pressure regulation, manual operation of exhaust valves is often required. In actual production, manual operation is difficult to achieve real-time and precise control. If exhaust is not timely, the air pressure inside the enclosure will be too high, which will not only affect the coating curing effect but may also pose a safety hazard. Therefore, we propose an antenna spraying and curing device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antenna spraying and curing device, comprising a high-temperature resistant chamber and a drying and curing mechanism disposed on its back and top, wherein the high-temperature resistant chamber is provided with a placement and adjustment mechanism, and the drying and curing mechanism comprises a centrifugal fan, a temperature controller and an exhaust rack, wherein a fan cover is fixedly installed at the air outlet of the centrifugal fan, and heating cables are fixedly connected to both ends of the temperature controller, wherein a sliding sleeve is connected to the exhaust rack via a fixed rod, and an air plug is fixedly installed at the bottom of the sliding sleeve, wherein an air passage is opened at the center of the bottom of the air plug, and an air outlet groove is opened on the side of the air plug.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set drying and curing mechanism, the heating cable can stably output heat under the control of the temperature controller. The centrifugal fan can quickly deliver airflow, and with the help of the fan hood, the airflow can be precisely guided into the high-temperature resistant chamber, accelerating the air circulation inside the chamber and ensuring that the temperature inside the chamber is always maintained within the optimal range required for antenna spray coating curing. This avoids quality problems such as bubbles and cracks in the antenna coating caused by temperature fluctuations. The coordinated design of the exhaust rack, air plug, sliding sleeve, limit spring and other components realizes intelligent adjustment of the air pressure inside the chamber without manual intervention. This can not only avoid the air pressure inside the chamber being too high and affecting the coating curing effect, but also keep the inside of the chamber clean and provide a stable internal environment for antenna spray coating curing.

Detailed Implementation

[0022] 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.

[0023] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 - Appendix Figure 7 An antenna coating curing device includes a high-temperature resistant chamber 1 and a drying and curing mechanism 7 disposed on its back and top. The high-temperature resistant chamber 1 is provided with a placement and adjustment mechanism 6. The drying and curing mechanism 7 includes a centrifugal fan 701, a temperature controller 703 and an exhaust rack 706. A fan cover 702 is fixedly installed at the air outlet of the centrifugal fan 701. Heating cables 704 are fixedly connected to both ends of the temperature controller 703. The exhaust rack 706 is connected to a sliding sleeve rod 709 through a fixed rod 707. An air plug 710 is fixedly installed at the bottom of the sliding sleeve rod 709. An air passage 711 is opened at the center of the bottom of the air plug 710. An air outlet groove 712 is opened on the side of the air plug 710.

[0024] Centrifugal fan 701 is an industrial fan that evenly guides airflow into the high-temperature resistant chamber 1 through the fan shroud 702, accelerating the circulation of internal hot air and preventing incomplete curing due to localized low temperatures. Temperature controller 703 is a digital display temperature controller that can preset the curing temperature. By monitoring the internal temperature in real time, it controls the on / off state of the heating cable 704 to prevent the coating from burning due to excessive temperature or the curing time from being prolonged due to excessively low temperature.

[0025] A vent 2 is provided at the center of the upper end of the high-temperature resistant chamber 1. Perforations 3 are provided on both sides of the upper end near the back of the high-temperature resistant chamber 1. Mounting holes 4 are provided at the center of the upper end near both sides of the high-temperature resistant chamber 1. Sliding grooves 5 are provided on both sides of the interior of the high-temperature resistant chamber 1.

[0026] The air outlet of the fan cover 702 is fixedly installed on the back of the high-temperature resistant chamber 1. The temperature controller 703 is fixedly installed on the upper surface of the high-temperature resistant chamber 1 near the back. The heating cable 704 is inserted into the through hole 3. A fastener 705 is sleeved on the outer wall of the heating cable 704. The fastener 705 is fixedly installed on the inner wall of the high-temperature resistant chamber 1.

[0027] The air outlet of the fan shroud 702 is fixed to the pre-set air vent on the back of the high-temperature resistant chamber 1 with bolts to ensure that the airflow enters completely and to avoid air leakage that would lead to heat waste. After the cable passes through the through hole 3, the outer wall is fitted with a fixing piece 705, which is locked to the inner wall of the high-temperature resistant chamber 1 with screws to prevent the cable from shaking under the impact of airflow and from being damaged by friction with the chamber wall. At the same time, it ensures that the cable is evenly distributed in the chamber, improving the uniformity of heating.

[0028] The exhaust bracket 706 is fixedly installed on the upper end of the exhaust port 2. The upper end of the fixing rod 707 is fixedly installed on the inner top of the exhaust bracket 706. The sliding sleeve rod 709 is slidably connected to the outer wall of the fixing rod 707. The upper end of the sliding sleeve rod 709 and the inner top of the exhaust bracket 706 are fixedly connected to the limiting spring 708. The limiting spring 708 is sleeved on the outer wall of the fixing rod 707. The air plug 710 is slidably connected to the inside of the exhaust bracket 706. The air passage 711 and the air outlet groove 712 are connected.

[0029] Fixed to the upper end of the exhaust port 2 by welding or bolting, the internal structure is a hollow cylinder and serves as the core channel for exhaust. A fixing rod 707 is vertically fixed to the top of the exhaust frame 706, and a sliding sleeve rod 709 is fitted over the fixing rod 707, allowing for smooth up-and-down sliding along the fixing rod 707. This provides guidance for the movement of the air plug 710, preventing it from shifting and causing sealing failure. The limiting spring 708 is made of stainless steel. In its initial state, the limiting spring 708 is in its natural extension, pushing the air plug 710 to press against the exhaust port 2, achieving a seal on the high-temperature resistant chamber 1. When the internal air pressure increases, the air pressure pushes the air plug 710 upwards, compressing the limiting spring 708, exposing the exhaust groove 712, and allowing gas to escape. When the air pressure decreases, the limiting spring 708 returns to its original position, and the air plug 710 re-seals, requiring no manual intervention.

[0030] Specifically, under the control of the temperature controller 703, the heating cable 704 can stably output heat, the centrifugal fan 701 can quickly deliver airflow, and together with the fan cover 702, the airflow can be precisely guided into the high-temperature resistant chamber 1, accelerating the air circulation inside the chamber and ensuring that the temperature inside the chamber is always maintained within the optimal range required for antenna coating curing. This avoids quality problems such as bubbles and cracks in the antenna coating caused by temperature fluctuations. The coordinated design of the exhaust bracket 706 with components such as the air plug 710, sliding sleeve rod 709, and limit spring 708 realizes intelligent adjustment of the air pressure inside the high-temperature resistant chamber 1 without manual intervention. This not only avoids excessive air pressure inside the chamber from affecting the coating curing effect, but also keeps the inside of the chamber clean, providing a stable internal environment for antenna coating curing.

[0031] Please see the appendix Figure 1 - Appendix Figure 4The placement adjustment mechanism 6 includes two sets of threaded rods 601, which are fixedly installed inside two sets of mounting holes 4. Multiple sets of placement frames 603 are slidably connected to the outer walls of the two sets of threaded rods 601. Adjustment nuts 602 are threadedly connected to the outer walls of the two sets of threaded rods 601 at the bottom of the placement frames 603.

[0032] The placement rack 603 is made of high-temperature resistant plastic, and has through holes at both ends that match the threaded rod 601. It can slide up and down along the threaded rod 601 to achieve flexible adjustment of the placement height.

[0033] Multiple sets of placement racks 603 are fixedly installed on both sides with sliding blocks 604. The sliding blocks 604 are slidably connected inside the sliding groove 5. The upper surface of the multiple sets of sliding blocks 604 is provided with a slot 605. A V-shaped frame 606 is slidably connected inside the slot 605.

[0034] The sliding block 604 is made of wear-resistant and high-temperature resistant nylon and is fixedly connected to both sides of the placement frame 603 by screws. Its shape is adapted to the sliding groove 5, and it can move up and down during sliding to guide the placement frame 603 and prevent it from shifting left and right when sliding along the threaded rod 601, thus avoiding collision between the antenna and the box wall and damaging the coating. The V-shaped frame 606 is made of elastic high-temperature resistant plastic and is adapted to the edge of the rod antenna or flat antenna. It can slide along the slot 605 to adjust the spacing, ensuring that the antenna always maintains the preset posture during the curing process and ensuring that the coating is uniformly heated and cured.

[0035] Specifically, rotating the adjusting nut 602 can cause the placement rack 603 to slide up and down along the threaded rod 601, thereby changing the spacing between two adjacent sets of placement racks 603. This allows for control of the placement height according to the spraying and curing requirements of antennas of different sizes and types within a certain range, preventing the antennas from colliding or the coating from sticking together due to insufficient space during the curing process. At the same time, multiple sets of antennas can be placed in the same batch of processing, improving the space utilization and batch processing capacity of the equipment. The V-shaped frame 606 can be adjusted in position according to the shape of the antenna, providing a stable limiting effect for the antenna and ensuring that the antenna always maintains the preset posture during the drying and curing process.

[0036] The working principle of this utility model is as follows: This utility model is an antenna spraying and curing device. Rotating the adjusting nuts 602 on the outer wall of the two sets of threaded rods 601 causes the adjusting nuts 602 to move up and down along the threaded rods 601. According to the height of the antenna to be cured, multiple sets of placement racks 603 are pushed to slide along the threaded rods 601. At the same time, the sliding blocks 604 on both sides of the placement racks 603 slide synchronously along the sliding grooves 5 inside the high-temperature resistant box 1 until the spacing between adjacent placement racks 603 is adapted to the antenna height.

[0037] Tighten the adjusting nut 602 to support and fix the position of the placement bracket 603 from the bottom; slide the V-shaped bracket 606 along the slot 605 on the upper surface of the sliding block 604, adjust the spacing of the V-shaped bracket 606, put the sprayed antenna into the V-shaped opening of the V-shaped bracket 606, and fix the antenna by the elastic clamping force of the V-shaped bracket 606 to prevent the antenna from shifting.

[0038] Close the door of the high-temperature resistant chamber 1 to ensure that the chamber is sealed. Turn on the temperature controller 703 and preset the temperature required for the antenna coating curing. After the temperature controller 703 is activated, the heating cables 704 connected to its two ends start to heat up and transfer heat into the high-temperature resistant chamber 1. At the same time, turn on the centrifugal fan 701. The airflow generated by the centrifugal fan 701 is guided into the chamber through the air outlet shroud 702, accelerating the air circulation inside the chamber and making the temperature inside the chamber rise evenly to the preset value.

[0039] The temperature controller 703 monitors the temperature inside the high-temperature resistant chamber 1 in real time. When the temperature is lower than the preset value, it controls the heating cable 704 to continue heating. When the temperature is higher than the preset value, it cuts off the power to the heating cable 704 to maintain a stable temperature inside the chamber and ensure that the antenna coating is cured evenly.

[0040] During the curing process, the water vapor and volatile solvents generated by heating inside the chamber cause the internal air pressure to rise. The high-pressure gas pushes the air plug 710 inside the exhaust frame 706 upward, and the sliding sleeve 709 at the top of the air plug 710 slides synchronously along the fixed rod 707, simultaneously compressing the limiting spring 708 sleeved on the outer wall of the fixed rod 707. After the air plug 710 moves upward, its side air outlet groove 712 communicates with the internal space of the exhaust frame 706. The high-pressure gas inside the chamber enters the air outlet groove 712 through the air passage 711 at the bottom center of the air plug 710, and then exits the chamber through the exhaust frame 706. When the internal air pressure drops to the normal range, the limiting spring 708 returns to its original position, pushing the sliding sleeve 709 and the air plug 710 downward. The air outlet groove 712 is blocked by the inner wall of the exhaust frame 706, thus resealing the chamber.

[0041] After the antenna coating has cured, first turn off the power to the heating cable 704, and keep the centrifugal fan 701 running until the temperature inside the high-temperature chamber 1 drops to room temperature. Turn off the centrifugal fan 701 and the temperature controller 703, open the chamber door, and take out the cured antenna.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
