[0002] The diaphragm compressor is a machine for air compression by repeated deformation of the diaphragm. In order to improve the fatigue strength of the diaphragm, it needs to be heat treated. The existing diaphragm heat treatment is to put multiple diaphragms into a crucible, and then place the crucible in a vacuum furnace for heat treatment. This heat treatment method is time-consuming and laborious for diaphragm feeding and removal. The existing vacuum furnace is large in size, uses traditional heat radiation heating form, and has slow heating and long time consumption.

[0041] In the embodiment, the driving device 7 comprises a driving motor 71, the driving motor 71 is fixedly connected with the rack 1, and the output shaft of the driving motor 71 is fixedly connected with a driving gear 72, the two sides of the driving gear 72 are engaged with racks 73, and the two racks 73 are respectively fixedly connected with the two sealing furnaces 8.

[0042] Working process and principle:

[0043] The initial two sealing furnaces 8 are in a state of moving away from each other, and the driving wheels 59 on the uppermost positioning assembly 5 are flush with the upper surface of the conveying line 9, the conveying line 9 runs, the outer side of the conveying line 9 is provided with a baffle for limiting the film sheet 10 on the conveying line 9, when the film sheet 10 passes through the conveying line 9 to the positioning assembly 5 and the uppermost proximity switch 11 detects that the film sheet 10 reaches above the positioning assembly 5, the conveying line 9 is paused.

[0044] The lifting motor 21 drives the gear two 27 to rotate the gear one 26, so that the driving block 22 rotates to drive the screw to rise, thereby driving the lifting plate 24 to rise by a certain height, and the film sheet 10 enters between the four driving wheels 59 and is supported by the disc 58.

[0045] As shown in Figure 4 At this time, the four driving wheels 59 have not contacted with the edges of the film sheet 10, and only play a role of preliminarily limiting the film sheet 10, the unopened positioning assembly 5 can smoothly pass through the middle of the conveying line 9, and the two driving strips 51 are in a state of moving away from each other and abutting against the fixed blocks 521.

[0046] After the driving wheel 59 on the second positioning assembly 5 also rises to the same level as the upper surface of the conveying line 9, the conveying line 9 is started again, so that the second film sheet 10 enters the upper side of the two positioning assemblies 5, and so on, so that all the film sheets 10 are placed between the four driving wheels 59 of the same positioning assembly 5, the initial positioning of all the film sheets 10 is completed, and finally the lifting plate 24 continues to rise to the area where the entire support frame 3 can be sealed by the sealing furnace 8.

[0047] Subsequently, the driving motor 71 is started, so that the driving gear 72 rotates, drives the two racks 73 to move the two sealing furnaces 8 close to each other, and the contact surfaces of the two sealing furnaces 8 are provided with sealing pads to assist sealing.

[0048] In the process of moving the two sealing furnaces 8 close to each other, the push plates 65 on the support frame one 63 and the support frame two 64 act on the driving bars 51 on different sides of the same positioning assembly 5, so that the two driving bars 51 slide on the guide rods 52 and move close to each other, the springs 53 are compressed, the driving bars 51 move close to each other, the sliding grooves 511 act on the sliding columns 541, and also make the rotating rods 54 rotate around the rotating shafts 56, drive the connecting rods 57 to open from the middle of the two conveying lines 9 to both sides, so that the driving wheels 59 which do not contact the film sheets 10 move to the position contacting the film sheets 10, thereby clamping the film sheets 10 between the four driving wheels 59, and realizing the positioning of the film sheets 10.

[0049] When the driving wheels 59 move close to the film sheets 10, the driving rollers 43 also move close to the discs 58 under the driving of the sealing furnaces 8, and finally the discs 58 contact the driving rollers 43, and the driving wheels 59 contact the film sheets 10.

[0050] Initially, the induction coil one 61 and the induction coil two 62 are in a separated state, and the circuit is not conducted, when the two sealing furnaces 8 move close to each other, the induction coil one 61 and the induction coil two 62 also move close to each other, the film sheets 10 are inserted into the middle area of the induction coil one 61 and the induction coil two 62, and finally the film sheets 10 are sleeved in the complete induction coil after the induction coil one 61 and the induction coil two 62 are connected.

[0051] Subsequently, the air in the cavity of the two sealing furnaces 8 is exhausted, so as to avoid that the oxygen remaining in the air oxidizes the film sheets 10 when the film sheets 10 are heated.

[0052] After the air is exhausted, the rotating motor 42 is started, all the driving rollers 43 rotate synchronously, drive all the discs 58 to rotate, and the discs 58, the driving wheels 59 and the film sheets 10 are in contact, so that the film sheets 10 rotate.

[0053] The current flows from the induction coil one 61 to the induction coil two 62 and then flows out from the induction coil one 61, forming a closed loop, at this time, the complete induction coil can perform induction heating on the diaphragm 10. The induction coil can cover the entire diameter area of the diaphragm 10, when the diaphragm 10 rotates, all diaphragms 10 and each position of the diaphragm 10 can be heated simultaneously. Avoid the disadvantage that when the diaphragm 10 is stacked, the deeper diaphragm 10 and the area cannot be heated synchronously, facilitate the uniform heating time and intensity of each diaphragm 10.

[0054] After the diaphragm 10 is heated, nitrogen is introduced into the diaphragm 10 by the gas source to cool the diaphragm 10, after cooling, the sealing furnace 8 is away from each other, the driving strip 51 is reset under the action of the spring 53, the connecting rod 57 is close to the middle of the two conveying boxes, the driving wheel 59 is away from the edge of the diaphragm 10 and the driving roller 43, the diaphragm 10 is loosened and stopped rotating.

[0055] Then the support frame 3 is lowered by a certain height each time, so that the diaphragm 10 returns to the conveying line 9, the conveying line 9 is started in reverse, driving the diaphragm 10 to separate from the positioning assembly 5, realizing the automatic unloading of the diaphragm 10.

[0056] From the common technical knowledge, the present application can be realized by other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above disclosed embodiments are only examples, and are not the only ones. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
