Description

Technical Field

[0001] This application relates to the field of varistor manufacturing technology, and in particular to a varistor drying device. Background Technology

The zinc oxide nonlinear resistive element is a compound semiconductor element made using ceramic technology with zinc oxide as the main material and the addition of various other trace elements. After being coated with solder paste, the varistor chip is sent to a drying device for drying, and the dried varistor chip is cooled by a fan.

[0003] Existing varistor drying equipment often cannot dry both sides of the varistor. After drying one side, it needs to be turned over by the operator, which results in relatively low drying efficiency and inconvenience in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a varistor drying device that overcomes the deficiencies of existing technologies. It aims to solve the problem that existing varistor drying devices often cannot dry both sides of the varistor, requiring workers to flip it after drying only one side, resulting in relatively low drying efficiency and inconvenience during use.

[0005] To achieve the above objectives, this application provides the following technical solution: a varistor drying device, comprising a drying frame, a drying trough above the drying frame, a drying chamber fixedly connected to the top of the drying frame, a conveying mechanism rotatably connected inside the drying trough, the conveying mechanism including a drying conveyor belt, the drying conveyor belt having multiple sets of through holes inside, a cooling frame at one end of the drying frame, a cooling conveyor belt rotatably connected to the top of the cooling frame, multiple sets of cooling components above the cooling frame, each of the multiple cooling components including a movable frame, multiple sets of cooling fans inside the movable frame, a bottom drying device inside the drying trough, the bottom drying device including a first fixed frame, multiple sets of infrared heating elements above the first fixed frame, and the bottom drying device located inside the conveying mechanism.

[0006] By adopting the above technical solution and setting up a conveying mechanism, the varistor is placed above the drying conveyor belt during use. After entering the drying tank, the drying chamber quickly dries the top of the varistor. As the varistor moves forward, the infrared heating element at the bottom continuously heats up. The drying conveyor belt has multiple through holes, allowing the infrared heating element to dry the bottom of the varistor. After drying, the varistor is quickly cooled by the cooling component at the top of the cooling conveyor belt. This drying chamber can quickly coordinate with the bottom drying device to achieve simultaneous drying of both sides of the varistor, further improving drying efficiency. Subsequent turning by operators is unnecessary, making it more convenient to use and enhancing the practicality of the device.

[0009] As a preferred technical solution of this application, two sets of supports are provided on one side of the cooling frame, and a bearing plate is fixedly connected to the bottom of each set of supports.

[0010] By adopting the above technical solution and setting up a bracket, the collection box can be placed directly on top of the support plate during use, which can better collect the varistor resistors and make it more convenient to use.

[0011] As a preferred technical solution of this application, a control panel is provided on one side of the drying rack, and the control panel is electrically connected to the bottom drying device, the cooling rack, the cooling component and the drying chamber.

[0014] By adopting the above technical solution and setting up the installation slot, the drying tank can be shielded during use, ensuring a stable internal temperature, reducing heat loss, and improving drying efficiency.

[0015] As a preferred technical solution of this application, a connecting plate is provided on one side of the cooling frame, and the other side of the connecting plate is located on one side of the conveying mechanism.

[0016] By adopting the above technical solution and setting a connecting plate, the stability of the pressure-sensitive resistor entering the cooling conveyor belt from above the conveying mechanism is ensured during use, thus improving the practicality of the device.

[0017] As a preferred technical solution of this application, the drying conveyor belt is provided with guards on both sides, and the drying frame is provided with observation windows on both sides.

[0018] By adopting the above technical solution and setting the protective edge, the overall stability of the drying conveyor belt can be ensured when transporting the varistor resistor, preventing the varistor resistor from falling off. The observation window allows for external observation of the drying effect, making it more convenient to use.

[0019] As a preferred technical solution of this application, the bottom of both the drying frame and the cooling frame are provided with multiple sets of support legs.

[0021] The beneficial effects of this application are: 1. By setting up a conveyor mechanism, the varistor is placed above the drying conveyor belt during use. After entering the drying chamber, the drying chamber quickly dries the top of the varistor. As the varistor moves forward, the infrared heating element at the bottom continuously heats up. The drying conveyor belt has multiple through holes, allowing the infrared heating element to dry the bottom of the varistor. After drying, the varistor is quickly cooled by the cooling component at the top of the cooling conveyor belt. This drying chamber can quickly coordinate with the bottom drying device to achieve simultaneous drying of both sides of the varistor, further improving drying efficiency. Subsequent flipping by operators is unnecessary, making it more convenient to use and enhancing the practicality of the device.

By setting a sliding groove, the position of the cooling component can be easily changed during use, better matching it with the pressure-sensitive resistor that needs to be cooled, making it more convenient during infusion and improving the practicality of the device.

Two sets of supports 204 are provided on one side of the cooling frame 2, and a bearing plate 205 is fixedly connected to the bottom of each set of supports 204.

[0027] By setting up the conveyor mechanism 4, during use, the varistor is placed above the drying conveyor belt 401. After entering the drying tank 101, the drying chamber 3 quickly dries the top of the varistor. As the varistor moves forward, the infrared heating element 502 at the bottom continuously heats up. Multiple through holes 402 are opened inside the drying conveyor belt 401, allowing the infrared heating element 502 to dry the bottom of the varistor. After drying, the varistor is quickly cooled by the cooling component 6 at the top of the cooling conveyor belt 202. This arrangement allows the drying chamber 3 to quickly coordinate with the bottom drying device 5, achieving simultaneous drying of both sides of the varistor, further improving drying efficiency. Subsequent flipping by personnel is unnecessary, making it more convenient to use and enhancing the device's practicality. By setting up the bracket 204, the collection box can be placed directly on top of the support plate 205 during use, allowing for better collection of the varistor and further enhancing convenience.

[0029] Reference Figure 1-5 The drying chamber 3 has mounting slots 302 at both ends, and each mounting slot 302 has a shielding and protective component 7 inside. The shielding and protective component 7 includes a second fixing frame 701, and a shielding curtain 702 is installed inside the second fixing frame 701.

The drying conveyor belt 401 has guardrails 403 on both sides, and the drying frame 1 has guardrails 403 on both sides. The observation window 102, with its protective edge 403, ensures the overall stability of the drying conveyor belt 401 when transporting the varistor resistor, preventing the resistor from falling off.

[0030] Working principle: By setting up the conveyor mechanism 4, the pressure-sensitive resistor is placed above the drying conveyor belt 401 during use. After entering the drying tank 101, the drying box 3 will quickly dry the top of the pressure-sensitive resistor. As the pressure-sensitive resistor moves forward, the infrared heating element 502 at the bottom will continuously heat up. The drying conveyor belt 401 has multiple sets of through holes 402, so that the infrared heating element 502 can dry the bottom of the pressure-sensitive resistor. After drying, the pressure-sensitive resistor will be quickly cooled by the cooling component 6 at the top of the cooling conveyor belt 202. This setting allows the drying box 3 to quickly cooperate with the bottom drying device 5 to achieve the effect of drying both sides of the pressure-sensitive resistor at the same time, further improving the drying efficiency. Afterwards, there is no need for the operator to flip it over, making it more convenient to use and improving the practicality of the device. By setting up the slide 201, the position of the cooling component 6 can be easily changed during use to better match the pressure-sensitive resistor that needs to be cooled, making it more convenient during infusion and improving the practicality of the device. Among them, by setting the bracket 204, the collection box can be placed directly on the top of the support plate 205 during use, which can better collect the varistor resistors and make it more convenient to use. By setting the control panel 8, the device can be better controlled during use, and the drying temperature data can be adjusted, making it more convenient to use and improving the practicality of the device. Meanwhile, by setting the mounting slot 302, the drying tank 101 can be shielded during use, ensuring that the internal temperature of the drying tank 101 is stable, reducing heat loss, and improving drying efficiency. In addition, by setting the connecting plate 203, the stability of the varistor as it enters the cooling conveyor belt 202 from above the conveying mechanism 4 is ensured during use, improving the practicality of the device. By setting the guard edge 403, the overall stability of the drying conveyor belt 401 is ensured when conveying the varistor during use, preventing the varistor from falling off. The observation window 102 allows for external observation of the drying effect, making it more convenient to use. By setting the support legs 103, the overall load-bearing capacity is improved, the overall stability is enhanced, and the practicality of the device is further improved.
