Detailed description of the invention
Now with specific embodiment, the utility model technical scheme required for protection is described in further detail by reference to the accompanying drawings.
As shown in Fig. 1 to Fig. 3, a kind of Low emissivity high-frequency seal machine of the present embodiment comprises high cyclic-wave generator 1, high-frequency tuning output device 2, head screening arrangement 3, wherein, head screening arrangement 3 is casings 31 with chamber door 32 that a metal is made, wherein adopt separate type to reduce installation difficulty between the base plate 313 in the portion of casing 31 and casing 31, first base plate 313 being placed on when mounted in the corresponding breach on workbench 4 makes base plate 313 contact with the metal shell of high-frequency tuning output device 2, casing 31 is installed again above base plate 313, and head screening arrangement 3 is connected with head 5.After installation, the high frequency output contact pin 21 having die holder 6 and high-frequency tuning output device 2 is covered in head screening arrangement 3 inside; High cyclic-wave generator 1 and high-frequency tuning output device 2 are provided with the metal shell be connected to each other, and the metal shell ground connection of high cyclic-wave generator 1, the base plate 313 of head screening arrangement 3 is connected with the metal shell of high-frequency tuning output device 2, because base plate 313 three of the metal shell of high cyclic-wave generator 1, the metal shell of high-frequency tuning output device 2 and head screening arrangement 3 is metal material and is directly connected, therefore this three also has the annexation of electric connection.
As shown in Figure 4 and Figure 5, case mouth 311 and the chamber door 32 of casing 31 form and are slidably connected, described chamber door 32 is driven by lift cylinder 33 and carries out elevating movement, and realize the open and close of chamber door 32 thus, impact failure is subject to when declining and touching the end in order to prevent chamber door 32, the metal clips 34 being provided with lateral bend in chamber door 32 on the upper edge of chamber door 32 and lower edge cushions chamber door 32 in impact when touching the end that declines, and metal clips 34 can also increase chamber door 32 and between casing 31 and base plate 313, contact area makes to form good electric connection between its three in addition; After chamber door 32 is closed completely, head screening arrangement 3 will become a closed conductor, the metal shell of high cyclic-wave generator 1, the metal shell of high-frequency tuning output device 2 and head screening arrangement 3 integral ground and be confined bed body structure, by the high-frequency electric field of the principle of electrostatic screen shielding from high cyclic-wave generator 1, high-frequency tuning output device 2, head 3, die holder 6 and high frequency output contact pin 21, because the high-frequency electric field of Low emissivity high-frequency seal machine is mainly from these parts, therefore to the high-frequency electric field amount of radiation that significantly can reduce complete machine after its shielding.
In order to the situation of casing 31 inside still can be observed after closing chamber door 32, chamber door 32 arranges the observation window 321 for observing casing 31 inside, and non-browning glass is set on observation window 321 and radiation proof net avoids high-frequency electric field radiation to leak from observation window 321;
The lamina tecti 312 at casing 31 top is provided with limit switch 35, when chamber door 32 falls closedown completely, the catch being arranged at edge on chamber door 32 can be depressed the connecting rod of limit switch 35 thus close lift cylinder 33, lift cylinder 33 is avoided to continue chamber door 32 toward drop-down damage chamber door, in addition, limit switch 35 also can be electrically connected with indicator lamp thus detect the closed condition of chamber door 32.
In use, start lift cylinder 33 chamber door 32 opened is landed closedown, Low emissivity high-frequency seal machine carries out welding to material, after welding completes, startup lift cylinder 33 rises the chamber door 32 of closing to open and take out the finished product after welding, and the fusion bonding process completing a Low emissivity high-frequency seal machine thus circulates.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
