Abstract
Description
Technical Field
[0001] This utility model belongs to the field of membrane switch technology, specifically a membrane switch drying device. Background Technology
[0002] Membrane switches are integrated operating systems that combine button functions, indicating elements, and instrument panels. They are widely used in electronic communications, electronic measuring instruments, industrial control, medical equipment, the automotive industry, smart toys, and home appliances. During the manufacturing process of membrane switches, a drying process is required.
[0003] In existing technologies, drying devices are often set up with multiple different temperature control zones and low-temperature preheating zones to process the equipment in order to meet different drying needs. However, this increases the size and floor space of the drying equipment, reduces the number of drying devices that can be placed in the factory, and thus affects the drying efficiency of the membrane switch.
[0004] Therefore, this utility model provides a membrane switch drying device. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A membrane switch drying device of this utility model includes a conveying assembly; a drying box is fixedly connected to the middle of the conveying assembly; a cylinder is fixedly connected to the top of the drying box; a lifting platform is fixedly connected to the bottom of the cylinder; a heating plate is fixedly connected to the bottom of the lifting platform; and a placement plate is slidably connected to the top of the conveying assembly. During operation, the cylinder is first activated, driving the lifting platform to rise and fall, thereby moving the heating plate up and down to adjust its position. Once the heating plate is adjusted to the appropriate position, it is activated, and then the membrane switch is placed on the placement plate. Activating the conveyor assembly moves the placement plate to the bottom of the drying chamber. Under the action of the heating plate, the membrane switches on the placement plate are dried. This allows for temperature regulation of the membrane switches by adjusting the position of the heating plate, thus reducing the footprint of the drying unit while meeting usage requirements. Furthermore, by using a cylinder to control the lifting platform's movement, the position of the heating plate is adjusted, thereby regulating the distance between the heating plate and the drying chamber. This achieves temperature control during the drying process of the membrane switches, reducing the need for separate temperature zones and further minimizing the footprint of the drying unit.
[0007] Preferably, the drying chamber has two fixed frames on one side, with a connecting pipe fixedly connected to the top of the fixed frame. A first external air pipe is connected to one side of the connecting pipe, and an air outlet is opened at the bottom of the connecting pipe. During operation, the placement plate moves towards the drying chamber under the drive of the conveying assembly. Before entering the drying chamber, it passes through the fixed frame. The first external air pipe is connected to an air pump. After the airflow enters the connecting pipe, it is dispersed from the air outlet and acts on the surface of the placement plate to clean the membrane switch placed on the top of the placement plate, reducing dust accumulation on the surface of the membrane switch. By setting up the connecting pipe, the first external air pipe, and the air outlet, the membrane switch to be dried is cleaned, reducing dust accumulation on its surface and affecting product quality.
[0008] Preferably, the drying chamber has two supports on the other side. A guide plate is fixedly connected to the top of the support, and a second external air pipe is connected to the top of the guide plate. Multiple air holes are connected to the bottom of the guide plate. During operation, after drying is completed, the drying chamber moves the placement plate away from the drying chamber area. Then, it passes through the support and the second external air pipe is connected to a cold air source. The cold air enters the guide plate and is released from the air holes, acting on the dried membrane switch to cool it and facilitate subsequent storage.
[0009] Preferably, the drying chamber is provided with heat-insulating curtains at both ends. The heat-insulating curtains are fixedly connected to the drying chamber. During operation, the heat-insulating curtains block the two ends of the drying chamber, insulate the inside of the drying chamber, reduce the heat diffusion rate inside the drying chamber, and prolong the time for the heat to dry the membrane switch.
[0010] Preferably, the placement plate has multiple placement slots in the middle, and the placement slots are opened at the top of the placement plate. During operation, the membrane switch is placed inside the placement slots on the placement plate. The placement slots limit and fix the membrane switch, reducing the phenomenon of the membrane switch shaking when it is driven and conveyed on the placement plate by the conveying component.
[0011] Preferably, a protective plate is provided on the outside of the placement slot. The protective plate is fixedly connected to the placement plate. During operation, the protective plate can first protect the membrane switch placed on the placement plate, reducing the phenomenon of the membrane switch sliding off the placement plate during the movement of the placement plate. At the same time, when passing through the drying oven, the protective plate will separate the heat insulation curtain, effectively reducing the possibility of the heat insulation curtain scraping against the membrane switch during the process of the placement plate passing through the heat insulation curtain.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The membrane switch drying device of this utility model uses a cylinder to control the lifting platform to raise and lower, thereby adjusting the position of the heating plate and adjusting the distance between the heating plate and the drying chamber. This achieves temperature control during the drying operation of the membrane switch, reducing the need for separate temperature zones and thus reducing the floor space occupied by the drying device.
[0014] 2. The membrane switch drying device of this utility model cleans the membrane switch to be dried by setting up a through pipe, a first external air pipe and an air outlet, thereby reducing dust on its surface and affecting product quality. Attached Figure Description

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figs. 1-2As shown in the embodiment of this utility model, a membrane switch drying device includes a conveying assembly 1. A drying chamber 11 is fixedly connected to the middle of the conveying assembly 1. A cylinder 12 is fixedly connected to the top of the drying chamber 11. A lifting platform 13 is fixedly connected to the bottom of the cylinder 12. A heating plate 14 is fixedly connected to the bottom of the lifting platform 13. A placement plate 15 is slidably connected to the top of the conveying assembly 1. During operation, the cylinder 12 is first activated, which drives the lifting platform 13 to rise and fall. Consequently, the heating plate 14 moves up and down, adjusting its position. Once the heating plate 14 is adjusted to the appropriate position, it is activated. Then, the membrane switch is placed on the placement plate 15, and the conveying assembly is activated. The conveying component 1 drives the placement plate 15 to move, transporting the placement plate 15 to the bottom of the drying chamber 11. Under the action of the heating plate 14, the membrane switch on the placement plate 15 is dried. In this way, the position of the heating plate 14 can be adjusted to regulate the drying temperature of the membrane switch, thereby reducing the footprint of the drying device while meeting the usage requirements. By setting the cylinder 12 to control the lifting platform 13 to lift and lower, the position of the heating plate 14 can be adjusted to achieve the effect of adjusting the distance between the heating plate 14 and the drying chamber 11, thereby achieving the effect of temperature regulation during the drying operation of the membrane switch, reducing the need to set different temperature zones separately, and thus reducing the footprint of the drying device.
[0024] like Figs. 1-3 As shown, the drying chamber 11 has two fixed frames 2 on one side. A connecting pipe 21 is fixedly connected to the top of the fixed frame 2. A first external air pipe 22 is connected to one side of the connecting pipe 21. An air outlet 23 is opened at the bottom of the connecting pipe 21. During operation, the placement plate 15 moves towards the drying chamber 11 under the drive of the conveying component 1. Before entering the drying chamber 11, it will pass through the fixed frame 2. The first external air pipe 22 is connected to the air pump. After the airflow enters the connecting pipe 21, it is dispersed from the air outlet 23 and acts on the surface of the placement plate 15 to clean the membrane switch placed on the top of the placement plate 15, reducing the dust on the surface of the membrane switch. By setting the connecting pipe 21, the first external air pipe 22 and the air outlet 23, the membrane switch to be dried is cleaned, reducing the dust on its surface and affecting the product quality.
[0025] like Figs. 1-4 As shown, two supports 3 are provided on the other side of the drying chamber 11. A guide plate 31 is fixedly connected to the top of the support 3. A second external air pipe 32 is connected to the top of the guide plate 31. Multiple air holes 33 are connected to the bottom of the guide plate 31. During operation, after drying is completed, the drying chamber 11 moves the placement plate 15 away from the range of the drying chamber 11. Then, it passes through the support 3 and the second external air pipe 32 is connected to a cold air source. The cold air enters the guide plate 31 and is emitted from the air holes 33, acting on the dried membrane switch to cool it and facilitate subsequent storage.
[0026] like Figs. 1-2 As shown, the drying chamber 11 is provided with heat-insulating curtains 4 at both ends. The heat-insulating curtains 4 are fixedly connected to the drying chamber 11. During operation, the heat-insulating curtains 4 block the two ends of the drying chamber 11, keep the inside of the drying chamber 11 warm, reduce the heat diffusion rate inside the drying chamber 11, and prolong the time for heat to dry the membrane switch.
[0027] like Figs. 1-5 As shown, the placement plate 15 has a plurality of placement slots 5 in the middle. The placement slots 5 are opened on the top of the placement plate 15. During operation, the membrane switch is placed inside the placement slots 5 on the placement plate 15. The placement slots 5 limit and fix the membrane switch, reducing the phenomenon of the membrane switch shaking when it is driven and conveyed on the placement plate 15 by the conveying component 1.
[0028] like Figs. 1-5 As shown, a protective plate 6 is provided on the outside of the placement slot 5. The protective plate 6 is fixedly connected to the placement plate 15. During operation, the protective plate 6 can first protect the membrane switch placed on the placement plate 15, reducing the phenomenon that the membrane switch slides out of the placement plate 15 during the movement of the placement plate 15. At the same time, when passing through the drying oven 11, the protective plate 6 will separate the heat insulation curtain 4, effectively reducing the possibility that the heat insulation curtain 4 will scratch the membrane switch during the process of the placement plate 15 passing through the heat insulation curtain 4.
[0029] Working principle: First, cylinder 12 is activated, which drives the lifting platform 13 to rise and fall. This causes the heating plate 14 to move up and down, adjusting its position. Once the heating plate 14 is in the desired position, it is activated. Then, the membrane switch is placed on the placement plate 15, and the conveying assembly 1 is activated. The conveying assembly 1 moves the placement plate 15 to the bottom of the drying chamber 11. Under the action of the heating plate 14, the membrane switch on the placement plate 15 is dried. This allows for adjustment of the drying temperature of the membrane switch by controlling the position of the heating plate 14, thus meeting usage requirements. This reduces the footprint of the drying unit. By controlling the lifting platform 13 with cylinder 12, the position of the heating plate 14 is adjusted, thereby regulating the distance between the heating plate 14 and the drying chamber 11. This achieves temperature control during the drying operation of the membrane switch, reducing the need for separate temperature zones and further reducing the footprint of the drying unit. The placement plate 15 moves towards the drying chamber 11 under the drive of the conveying assembly 1. Before entering the drying chamber 11, it passes through the fixing frame 2. The first external air pipe 22 connects to the air pump. After the airflow enters the pipe 21, it is emitted from the air outlet 23, acting on the surface of the placement plate 15 and the membrane placed on top of the placement plate 15. The switches undergo cleaning to reduce dust accumulation on their surfaces. By using a conduit 21, a first external air pipe 22, and an air outlet 23, the membrane switches to be dried are cleaned, reducing surface dust and ensuring product quality. Once drying is complete, the drying chamber 11 moves the placement plate 15 away from its range. The cold air then passes through a support 3 and a second external air pipe 32, connecting to a cold air source. The cold air enters the air guide plate 31 and dissipates through the air holes 33, cooling the dried membrane switches for easier storage. An insulation curtain 4 separates the two ends of the drying chamber 11, insulating the interior and reducing the risk of dust accumulation. The heat diffusion rate is increased, extending the drying time of the membrane switch. The membrane switch is placed inside the placement groove 5 on the placement plate 15. The placement groove 5 limits and fixes the membrane switch, reducing the phenomenon of the membrane switch shaking when it is driven and conveyed on the placement plate 15 by the conveying component 1. The protective plate 6 can first protect the membrane switch placed on the placement plate 15, reducing the phenomenon of the membrane switch sliding off the placement plate 15 during the movement of the placement plate 15. At the same time, when passing through the drying chamber 11, the protective plate 6 will separate the heat insulation curtain 4, effectively reducing the possibility of the heat insulation curtain 4 scraping the membrane switch during the process of the placement plate 15 passing through the heat insulation curtain 4.
