DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example

[0029] like Figure 1 , Figure 2 As shown, Figure 1 What is shown is a schematic diagram of the main view of the crystal curing furnace in the embodiment; Figure 2 Shown is a cross-sectional schematic diagram of a crystal curing furnace in an embodiment;

[0030] The device includes:

[0031] The curing furnace 10, the conveying assembly 20 and the crystal support seat 40, the curing furnace 10 includes an input port 13 and an output port 14 arranged opposite to each other; the conveying assembly 20 is mounted at the lower end of the curing furnace 10; the crystal support seat 40 is placed on the conveying assembly 20 for conveyance.

[0032] The sizes of the input port 13 and the output port 14 match the crystal support 40 and can allow the crystal support 40 to pass through. The crystal to be cured is placed on the crystal support 40 and transported from the input port 13 into the curing furnace 10 through the conveying assembly 20 for curing, and then output from the output port 14.

[0033] like Figure 2 As shown, Figure 2 Shown is a cross-sectional schematic diagram of a crystal curing furnace in an embodiment;

[0034] The curing furnace 10 includes an internal curing chamber 11 and a dust removal chamber 12 located outside the curing chamber 11. A heating element 111 is disposed inside the curing chamber 11. The heating element 111 is disposed at the top and front and rear sides of the curing chamber 11. A plurality of nitrogen injection ports 112 are also disposed inside the curing chamber 11. A fan 121 is disposed in the dust removal chamber 12.

[0035] Specifically, the heating element 111 is a heating tube, and four nitrogen injection ports 112 are set for injecting nitrogen into the curing chamber 11. The fan 121 is symmetrically arranged at the top of both sides of the dust removal chamber 12, connected to the outside world, and draws out the air in the dust removal chamber 12 to achieve dust removal.

[0036] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, Figure 2 Shown is a cross-sectional schematic diagram of a crystal curing furnace in an embodiment; Figure 3 It is shown that Figure 2 A schematic diagram of the structure enlargement at point A; Figure 4 What is shown is a top view schematic diagram of the cooperation between the crystal placement seat and the tooth plate; Figure 5 Shown is a schematic structural diagram of a crystal placement seat.

[0037] The conveying assembly 20 includes a conveying belt 21;

[0038] The limiting plate 30 is also included. The limiting plate 30 is symmetrically arranged on the side wall of the curing furnace 10, and the limiting plate 30 is located above the conveyor belt 21. The limiting plate 30 does not contact the upper end surface of the conveyor belt 21; a limiting channel is formed between the limiting plates 30;

[0039] The crystal support 40 is also included. The crystal support 40 is placed on the conveying assembly 20 and is conveyed along the limiting channel.

[0040] The crystal support seat 40 includes a counterweight base 41, a rotating shaft 42 is arranged at the middle part of the top of the counterweight base 41, a bearing net box 43 is arranged at the other end of the rotating shaft 42, and a gear 44 is sleeved on the outer wall of the bearing net box 43;

[0041] A tooth plate 50 is provided on the inner wall of the curing chamber 11. The tooth plate 50 is arranged parallel to the conveyor belt 21 and is matched with the height of the gear 44. After the crystal support seat 40 enters the curing chamber 11, the tooth plate 50 is meshed with the gear 44, and the meshing section of the tooth plate 50 drives the gear 44 to rotate continuously, that is, the supporting mesh box 43 rotates continuously during the conveying process.

[0042] The limit plate 30 disposed above the conveyor belt 21 guides the crystal support 40 transported on the conveyor belt 21, so that it is transported according to the limit channel, so that the tooth plate 50 and the gear 44 are smoothly meshed, and the crystal support 40 can be prevented from falling off the conveyor belt 21; the limit plate 30 is disposed on the front and rear side walls of the curing furnace 10, and is installed to the corresponding position by the installation rod; the setting height of the limit plate 30 is slightly lower than the height of the counterweight base 41;

[0043] The carrying net box 43 is a U-shaped net for placing the crystal; the carrying net box 43 is rotatably arranged on the top of the counterweight base 41, and the gear 44 arranged outside the carrying net box 43 cooperates with the tooth plate 50 arranged in the curing chamber 11, so that after the crystal support seat 40 is transported to the curing chamber 11, under the action of the tooth plate 50, the carrying net box 43 can be continuously rotated while the crystal support seat 40 is being transported;

[0044] Specifically, during transportation, the friction force between the counterweight base 41 and the conveyor belt 21 must be greater than the force of the rotation of the load-bearing net box 43 to ensure that the counterweight base 41 does not rotate with the rotation of the load-bearing net box 43 and maintains the forward state of transportation.

[0045] The continuous rotation of the carrier mesh box 43 in the curing chamber 11 during the conveying process can, on the one hand, help to evenly distribute the heat inside the curing chamber 11, so that the crystals on the carrier mesh box 43 receive more even heat, reduce temperature gradients, reduce stress in the crystals, and reduce defects; on the other hand, it can evenly distribute the nitrogen inside the curing chamber 11, thereby improving the overall quality and consistency of the crystals.

[0046] like Figure 2 , Figure 3 As shown, Figure 2 Shown is a cross-sectional schematic diagram of a crystal curing furnace in an embodiment; Figure 3 It is shown that Figure 2 A schematic diagram of the structure enlargement at point A;

[0047] The input port 13 and the output port 14 of the curing oven 10 are both hingedly provided with flap doors 15;

[0048] The flap doors 15 are respectively arranged inside the input port 13 and outside the output port 14. The flap doors 15 naturally block the input port 13 and the output port 14 under the action of gravity. When the crystal support seat 40 is transported to the input port 13, the crystal support seat 40 resists and flips up the flap door 15, which does not affect the crystal support seat 40 entering the curing furnace 10. After the crystal support seat 40 is completely entered, the flap door 15 will naturally fall down to close the input port 13, and the same applies to the flap door 15 at the output port 14.

[0049] By providing the flap door 15 , the airtightness of the interior of the curing oven 10 can be enhanced, and interference from dust and impurities and heat loss during the curing process can be further avoided.

[0050] A clamping cavity 113 is arranged in the side wall of the curing cavity 11; the arranged clamping cavity 113 can form an isolation layer in the side wall of the curing cavity 11 to reduce the influence of the external environment on the temperature of the inner cavity, which helps to maintain the stability and uniformity of the temperature of the inner cavity and reduce temperature fluctuations; it also makes the curing cavity 11 have good thermal insulation performance, can reduce heat conduction, and make the temperature in the curing cavity 11 easier to control.

[0051] like Figure 2 As shown, Figure 2 Shown is a cross-sectional schematic diagram of a crystal curing furnace in an embodiment;

[0052] The conveying assembly 20 includes a fixed plate 22, a driving wheel 1 23 and a driving wheel 2 24. The fixed plate 22 is arranged on both sides of the curing furnace 10, and the driving wheel 1 23 is arranged at the other end of the fixed plate 22. The outer edges of the driving wheel 1 23 and the driving wheel 2 24 are connected by a belt 25. A motor 26 is also provided, and the output shaft of the motor 26 is connected to the driving wheel 2 24. The conveying belt 21 is sleeved on the outer side of the driving wheel 1 23 on both sides.

[0053] The motor 26 is a stepper motor that can be used in conjunction with a microcontroller or a PLC (programmable logic controller) to achieve complex motion control. This allows the motion mode of the conveyor assembly 20 to be flexibly adjusted according to different production requirements; for example, the speed during the curing stage can be appropriately lowered to achieve the best curing effect.

[0054] Working principle: When the device is in use, first turn on the equipment operation switch, then connect the nitrogen injection port 112 to the nitrogen storage device, inject nitrogen into the curing chamber 11, and simultaneously turn on the heating element 111 to heat the inner cavity of the curing chamber 11. After the temperature reaches the set value, the crystal support seat 40 is placed on the conveying assembly 20 and is conveyed along the limiting channel formed by the limiting plate 30. After the crystal support seat 40 is transported to the curing chamber 11, under the action of the gear 44 and the tooth plate 50, the crystal support seat 40 is transported while the supporting mesh box 43 will rotate continuously, so that the crystal on the supporting mesh box 43 is evenly heated and cured.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
