Description

Technical Field

[0001] This utility model relates to the technical field of resonator bonding apparatus, and in particular to a small crystal resonator bonding apparatus. Background Technology

[0002] A crystal resonator is a high-precision frequency control element that utilizes the piezoelectric effect of quartz crystals to achieve the mutual conversion between electrical signals and mechanical vibrations.

[0003] Existing crystal resonator bonding equipment includes a loading device, a low-temperature heating device, a high-temperature heating device, a cooling device, and a loading device. The low-temperature and high-temperature heating devices each have several heating tubes spaced apart. During bonding, the bonded crystal resonator is placed in the loading device, which then transports it to the low-temperature heating device, followed by the high-temperature heating device, then the cooling device, and finally the loading device. In this type of resonator bonding equipment, the low-temperature and high-temperature heating devices are located below the crystal resonator, heating only the lower part of the crystal resonator. Furthermore, the heat from the heating tubes is not concentrated, resulting in uneven heating of the crystal resonator.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:

[0005] Existing dip-extraction resonator baking devices result in uneven heating of crystal resonators. Utility Model Content

[0006] The purpose of this invention is to provide a small crystal resonator baking device, which solves the technical problem of uneven heating of crystal resonators in existing dip-extraction resonator baking devices.

[0007] Utility model solution:

[0008] This utility model provides a small crystal resonator bonding device, including a housing, a frame, an upper heating assembly, and a lower heating assembly. The housing has support legs, a switch door, and ventilation openings. The frame is located in the middle of the housing and has several first air holes. The ventilation openings are located at both ends of the frame. The switch door is hinged to the housing. The support legs are located at the bottom of the housing. The upper heating assembly includes a hot air blower, a baffle plate, and an air guide box. The hot air blower is installed in the housing. The baffle plate is fixedly installed in the housing and has a semi-circular protrusion located directly below the output end of the hot air blower. The air guide box is fixedly installed in the housing and covers the baffle plate, and has several second air holes. The lower heating assembly has the same structure as the upper heating assembly, with the upper heating assembly located above the frame and the lower heating assembly located below the frame.

[0009] Furthermore, the wind baffle is provided with a first arc-shaped portion, and the air guide box is provided with a second arc-shaped portion.

[0010] Furthermore, the air guide box is provided with an air gathering section, and a plurality of second air holes are disposed in the air gathering section.

[0011] Furthermore, the frame is provided with a limiting frame.

[0012] Furthermore, the door is equipped with a handle and a window.

[0013] Beneficial effects:

[0014] This invention provides a small crystal resonator bonding device. When bonding a small crystal resonator is required, the switch door is opened, the small crystal resonator to be bonded is placed on the rack, the switch door is closed, and the hot air fan is started. After the hot air fan delivers hot air into the chamber, due to its large impact force, the semi-circular protrusion encounters the hot air, causing the hot air to diffuse evenly around the air baffle. Then, the hot air is guided through the air guide box and enters the second air hole, thus achieving uniform bonding above and below the small crystal resonator. The hot air generated by the hot air fan in the upper heating assembly flows out from the vent above the rack, and the hot air generated by the hot air fan in the lower heating assembly flows out from the vent below the rack, avoiding the mixing of hot air from the upper and lower parts, thereby ensuring uniform bonding of the small crystal resonator. Therefore, this small crystal resonator bonding device provides relatively uniform heating of the crystal resonator. Attached Figure Description

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] This embodiment provides a small crystal resonator bonding device. Please refer to [reference needed]. Figure 1-3 As shown, the device includes a housing 100, a shelf 200, an upper heating assembly 300, and a lower heating assembly 400. The housing 100 is provided with support legs 110, a door 120, and a vent 130. The shelf 200 is located in the middle of the housing 100 and has several first air holes 210. The vents 130 are located at both ends of the shelf 200. The door 120 is hinged to the housing 100, and the support legs 110 are located at the bottom of the housing 100. The upper heating assembly 300 includes a hot air blower 310, a baffle plate 320, and an air guide box 330. The hot air blower 310 is installed in the housing 100, and the wind baffle 320 is fixedly installed in the housing 100. The wind baffle 320 has a semi-circular protrusion 321, which is located directly below the output end of the hot air blower 310. The air guide box 330 is fixedly installed in the housing 100 and covers the wind baffle 320. It has several second air holes 331. The lower heating component 400 has the same structure as the upper heating component 300. The upper heating component 300 is located above the frame plate 200, and the lower heating component 400 is located below the frame plate 200.

[0031] Specifically, the housing 100 provides a space for baking glue, and the support legs 110 support the housing 100 at a certain height to facilitate the installation of the hot air blower 310 of the lower heating assembly 400. The door 120 controls the opening or sealing of the housing 100. Four ventilation openings 130 are located on both sides of the rack plate 200. The first air hole 210 is used to improve the baking glue efficiency below the small crystal resonator. The upper heating assembly 300 is used to heat the upper part of the small crystal resonator. The hot air blower 310 is used to provide hot air. The baffle plate 320 and the air guide box 330 work together to control the flow direction of the hot air. The semi-circular protrusion 321 is set to evenly disperse the hot air that just enters the housing 100 to ensure uniform hot air output. The lower heating assembly 400 is used to heat the lower part of the small crystal resonator. When it is necessary to heat the small crystal resonator with glue, open the switch door 120, place the small crystal resonator to be heated on the rack 200, close the switch door 120, and start the hot air blower 310. After the hot air blower 310 delivers hot air into the housing 100, due to its large impact force, the semi-circular protrusion 321 meets the hot air, causing the hot air to spread evenly around the wind baffle 320. Then, the hot air is guided through the air guide box 330 and enters the second air hole 331, thus heating the small crystal resonator with glue evenly above and below. The hot air generated by the hot air blower 310 in the upper heating component 300 flows out from the vent 130 above the rack 200, and the hot air generated by the hot air blower 310 in the lower heating component 400 flows out from the vent 130 below the rack 200, avoiding the mixing of the upper and lower hot air impacts, thereby ensuring that the small crystal resonator is heated with glue evenly.

[0032] In this embodiment, the wind baffle 320 is provided with a first arc-shaped portion 322, and the air guide box 330 is provided with a second arc-shaped portion 332.

[0033] Specifically, the first arc-shaped portion 322 and the second arc-shaped portion 332 correspond to each other, so that the hot air on one side of the wind baffle 320 can smoothly enter the other side of the wind baffle 320.

[0034] In this embodiment, the air guide box 330 is provided with an air gathering part 333, and a plurality of second air holes 331 are provided in the air gathering part 333.

[0035] Specifically, the air-concentrating unit 333 is located directly above the rack 200 to reduce heat loss and improve the efficiency of baking the glue.

[0036] In this embodiment, the frame 200 is provided with a limiting frame 220.

[0037] Specifically, the setting of the limit frame 220 facilitates the positioning and limiting of the plate containing the small crystal resonator, making it convenient for operators to operate.

[0038] In this embodiment, the door 120 is equipped with a handle 121 and a window 122.

[0039] Specifically, the handle 121 is designed to facilitate the use of opening and closing the door 120, and there are two windows 122 to facilitate the viewing of the bonding status of the small crystal resonator.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
