[0012] The frame box material receiving mechanism comprises: a material receiving longitudinal moving mechanism, a material receiving lifting mechanism installed on the material receiving longitudinal moving mechanism, and a frame box clamping mechanism installed on the material receiving lifting mechanism, wherein the frame box clamping mechanism is used to clamp and move the frame box.

[0013] When the frame box clamping mechanism drives the frame box to move to a predetermined position, the frame pushing mechanism is used to move the frame in the frame box to the frame transmission mechanism.

[0014] In a further embodiment, the frame transmission mechanism includes: a frame transfer track, a frame longitudinal movement component, a track rotation component, a frame placement track, a frame lateral movement component, a frame vertical movement component and a frame clamping component.

[0015] The frame transfer track is arranged on the side of the frame box material receiving mechanism away from the frame pushing mechanism, the frame longitudinal moving component is arranged on the side of the frame transfer track away from the frame box material receiving mechanism, the track rotating component is installed on the frame longitudinal moving component, the frame placement track is installed on the track rotating component, and the frame longitudinal moving component is used to drive the frame placement track to move in the direction of the second transverse path.

[0023] In a further embodiment, the feeding mechanism includes: a silo, a fixed plate, a push plate and a power member.

[0024] A plurality of the fixed plates are arranged in sequence between the material bin and the material discharge mechanism in a stepped manner, a push plate is arranged between every two of the fixed plates, and the power member is connected to the push plate.

[0029] The distance between the height baffle plate and the conveyor belt is greater than the diameter of the rubber particles, and the distance between the height baffle plate and the conveyor belt is less than the height of the rubber particles. The height baffle plate can be used to block the rubber particles standing on the conveyor belt to the return channel.

[0030] In a further embodiment, the rack transfer device includes: a transfer transverse moving mechanism, a transfer transverse frame, a transfer longitudinal moving mechanism, a transfer longitudinal frame and a transfer vertical moving mechanism connected in sequence.

[0032] The two transfer transverse frames are installed on the transfer transverse moving mechanism, and the two groups of transfer longitudinal moving mechanisms, the transfer longitudinal frame and the transfer vertical moving mechanism are respectively installed on the transfer transverse frame.

[0033] The transfer transverse movement mechanism is extended along the second transverse path.

[0034] The transfer longitudinal movement mechanism is used to drive the transfer vertical movement mechanism to move between the second transverse path and the first transverse path.

[0035] The material rack loading device is installed on one transfer vertical moving mechanism, and the material rack unloading device is installed on another transfer vertical moving mechanism.

[0036] In a further embodiment, the transfer longitudinal movement mechanism includes a transfer longitudinal gear rack mechanism and a transfer longitudinal guide rail mechanism installed on the transfer transverse frame, and a transfer longitudinal motor installed on the transfer longitudinal gear rack mechanism.

[0037] The racks and guide rails of the longitudinal gear and rack mechanism and the longitudinal guide rail mechanism are installed on both sides of the inner wall of the transverse frame of the transfer, the gears and guides of the longitudinal gear and rack mechanism and the longitudinal guide rail mechanism are installed on both sides of the longitudinal frame of the transfer, the rack and guide rail are arranged between the gears and the guide rails, and the longitudinal motor of the transfer is installed at the end of the longitudinal frame of the transfer away from the first transverse path. Compared with the prior art that extends the rack and guide rail into the first transverse path, through the cooperation between the motor, rack, guide rail, gear and guide rail, the rack and guide rail can realize the transfer of the frame and the rubber particles without extending into the first transverse path, further releasing the space above the sheet feeding device and the rubber particle feeding device.

[0038] In a further embodiment, the preheating device is installed on a transfer transverse frame, and the preheating device is arranged under the transfer longitudinal moving mechanism. The transfer longitudinal moving mechanism, the transfer vertical moving mechanism and the material rack loading device cooperate to place the frame on the preheating device for preheating. The preheating device is moved to a position cooperating with the hot pressing device through the transfer transverse moving mechanism, and then the frame on the preheating device is moved to the hot pressing device through the material rack loading device and the material rack transfer device. Preheating is performed during the movement, thereby reducing the preheating waiting time and improving the processing efficiency.

[0039] In a further embodiment, the material rack loading device includes: a frame clamping mechanism installed on the material rack transfer device.

[0040] The frame clamping mechanism comprises: a frame clamping frame, a vertical elastic member, a vertical movable plate, a transverse cylinder and a clamping claw assembly.

[0042] When the claw assembly contacts the lower surface of the frame, the vertical elastic member applies a downward force to the upper surface of the frame through the vertical movable plate. Compared with the prior art, the cooperation of the vertical elastic member and the claw assembly can reduce the use of one vertical cylinder, which not only reduces the cost, but also reduces the weight borne by the cantilever structure formed when the transfer longitudinal frame extends to the first horizontal path, thereby improving the working stability of the material rack transfer device.

[0043] The beneficial effect of the present invention is as follows: the present application installs the material rack loading device and the material rack unloading device on the material rack transferring device, so that the material rack transferring device is used to drive the material rack loading device and the material rack unloading device to move between the second transverse path and the first transverse path. When the material rack transferring device drives the material rack loading device to move to the second transverse path, the preheating device, the hot pressing device and the cutting and unloading device, the space above the sheet loading device and the pellet loading device can be released, which solves the problem that the space above the frame transmission device and the material transmission device in the prior art is small, which is not conducive to the adjustment and maintenance of the plastic sealing system, so that the plastic sealing system can meet the production requirements of the silicon carbide module.

[0054] The present application discloses a fully automatic silicon carbide module plastic sealing system, which is provided with control devices such as sensors and PLCs. The sensors, electric components and pneumatic components are connected to the control devices, and are controlled by the control devices to perform automatic plastic sealing. The material rack feeding device is installed on the material rack transfer device, so that the material rack transfer device drives the material rack feeding device to move, thereby releasing the space above the sheet feeding device and the granule feeding device, solving the problem that the space above the frame transmission device and the material transmission device in the prior art is small, which is not conducive to the adjustment and maintenance of the plastic sealing system, so that the plastic sealing system can meet the production requirements of the silicon carbide module.

[0059] The rack loading device 1 and the rack unloading device 8 are installed on the rack transfer device 2, and the rack transfer device 2 is used to drive the rack loading device 1 and the rack unloading device 8 to move between the second transverse path 200 and the first transverse path 100.

[0060] Regarding the frame loading device 3, as Figure 1-3 The frame loading device 3 shown includes: a frame box, a frame box material rack 31, a frame box material receiving mechanism 32, a frame pushing mechanism 33 and a frame transmission mechanism 34.

[0061] The frame box is arranged in the frame box material rack 31 , the frame box receiving mechanism 32 is arranged on one side of the frame box material rack 31 , the frame pushing mechanism 33 is arranged on one side of the frame box receiving mechanism 32 , and the frame transmission device is arranged on the other side of the frame box receiving mechanism 32 .

[0063] When the frame box clamping mechanism drives the frame box to move to a predetermined position, the frame pushing mechanism 33 is used to move the frame in the frame box to the frame transport mechanism 34 .

[0064] The frame box material rack 31 includes a full material rack and an empty material rack, and both the full material rack and the empty material rack are provided with a frame box longitudinal conveying mechanism. The full material rack drives the frame box to move toward the frame box receiving mechanism 32 through the frame box longitudinal conveying mechanism, and the empty material rack drives the frame box to move away from the frame box receiving mechanism 32 through the frame box longitudinal conveying mechanism. The frame box longitudinal conveying mechanism can be a synchronous belt mechanism, or it can be a conveying mechanism such as a screw mechanism, a gear rack mechanism, etc.

[0065] The frame box receiving mechanism 32 and the frame pushing mechanism 33 belong to the prior art and are not limited here.

[0070] exist Figure 2 In the illustrated embodiment, a frame transfer rail 341 and two frame placement rails 343 are provided. When two frames are placed on one frame placement rail 343, a frame transverse moving assembly 344 is used to drive the other frame placement rail 343 to align with the frame transfer rail 341. When a frame is placed on each of the two frame placement rails 343, the frame placement rails 343 are extended a predetermined distance in the direction of the second transverse path 200 by the frame longitudinal moving assembly 342, and then the two frame placement rails 343 are driven to rotate by the rail rotating assembly so that the position of the frame matches the material rack loading device 1.

[0073] Compared with the square positioning groove 3432 of the frame placement rack in the prior art, the rail groove 3431 cooperates with the frame clamping assembly 346 to clamp the frame from the thickness direction of the frame, so that when the frame is long, the frame clamping assembly 346 can support the side of the frame away from the frame clamping assembly 346 when clamping the frame.

[0087] like Figure 5 The side wall of the height baffle plate 433 is set at an obtuse angle to the forward direction of the conveyor belt 432. When the upright rubber particles move to the height baffle plate 433, they will be blocked by the height baffle plate 433 and move into the return channel 434, and then move into the material bin 411 of the loading mechanism through the return channel 434.
