[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0026] The term "perpendicular" is used to describe an ideal state. In actual production or use, a state approximately perpendicular to the vertical may exist. The term "parallel" is used to describe an ideal state. In actual production or use, a state approximately parallel may exist.

[0027] It should be noted that when an element is referred to as being "fixed" to another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected" to another element, it may be directly connected to the other element or there may be an intermediate element. When an element is referred to as being "disposed on" another element, it may be directly disposed on the other element or there may be an intermediate element.

[0028] As production capacity continues to increase in the photovoltaic semiconductor industry chain, the diameter of furnace tubes in furnace cabinets is increasing, and the furnace doors attached to the tubes are also becoming larger and heavier. The furnace tubes are equipped with mounting arms, and the furnace doors are fixed to the mounting arms with bolts.

[0029] In the related art, the operator carries the furnace door, raises the furnace door assembly to the same height as the installation arm of the furnace tube, and then fixes it with bolts. However, the furnace door is heavy, which increases the operator's workload and makes installation more difficult.

[0030] An embodiment of the present application provides a furnace door auxiliary device that can move and raise and lower the furnace door to reduce the workload of the operator. The furnace door auxiliary device includes a base, a supporting member, and a lifting member. A plurality of movable wheels are provided at the bottom of the base. The supporting member includes a frame and at least two supporting blocks. The frame is provided on the base, and the two supporting blocks are connected to the side of the frame facing away from the base at intervals. The two supporting blocks are used to support the outer peripheral surface of the furnace door. The lifting member connects the base and the frame and is used to drive the frame to move relative to the base, thereby driving the furnace door to rise or fall.

[0031] In the above embodiment, the furnace door is supported by two support blocks to prevent it from rolling relative to the frame. The support blocks also space the furnace door from the frame to prevent damage to the furnace door caused by contact between the furnace door and the frame. The base drives the support member to move by rolling on the moving wheels, thereby moving the position of the furnace door. The support member is driven to move relative to the base by the lifting member, thereby raising or lowering the furnace door. The above auxiliary device is applied to the installation of the furnace door. After the furnace door is transferred to the bottom of the furnace tube via the base and moving wheels, the furnace door is raised to the same height as the installation arm of the furnace tube via the lifting member so that the furnace door can be connected to the installation arm of the furnace tube to complete the installation of the furnace door. The movement and lifting of the furnace door are both performed by the furnace door auxiliary equipment, which reduces the workload of the operator.

[0032] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0033] See also Figure 1 An embodiment of the present application provides a furnace door 200 auxiliary device 100 for assisting the movement and lifting of the furnace door 200.

[0034] The auxiliary device 100 of the furnace door 200 includes a base 10, a bearing member 20 and a lifting member 30 (see Figure 2 ). See Figure 1 and see Figure 2, the lifting member 30 connects the base 10 and the bearing member 20. The bearing member 20 is used to support the furnace door 200. A plurality of moving wheels are provided at the bottom of the base 10 to facilitate the base 10 to drive the bearing member 20 and the furnace door 200 to move, so that the furnace door 200 can be transferred to the bottom of the furnace tube. The lifting member 30 is used to drive the bearing member 20 to move relative to the base 10, thereby driving the furnace door 200 to rise or fall, so that the furnace door 200 can rise to the same height as the installation arm of the furnace tube, so that the furnace door 200 can be connected to the installation arm of the furnace tube to realize the installation of the furnace door 200. Therefore, the furnace door 200 auxiliary device 100 can assist the operator in moving and lifting the furnace door 200, reducing the operator's workload.

[0035] See also Figure 2 The furnace door 200 is cylindrical. The outer circumference of the furnace door 200 is a cylindrical surface. The support member 20 includes a frame 21 and two support blocks 22. The frame 21 is connected to the base 10 via a lifting member 30. The two support blocks 22 are spaced apart along the first direction X and connected to the side of the frame 21 facing away from the base 10. The two support blocks 22 are used to support the outer circumference of the furnace door 200. When the two support blocks 22 support the furnace door 200, the two support blocks 22 are located on either side of the center 200a of the furnace door to prevent the furnace door 200 from rolling relative to the frame 21 in the direction of the spacing between the two support blocks 22 after the furnace door 200 is installed on the support member 20. The two support blocks 22 support the furnace door 200 and also space the furnace door 200 from the frame 21, preventing contact between the furnace door 200 and the frame 21 and causing damage to the furnace door 200. This protects the furnace door 200 and prevents the furnace door 200 from interfering with the raising and lowering of the frame 21.

[0036] When using the furnace door 200 auxiliary device 100 to complete the installation of the furnace door 200, the furnace door 200 is placed on the two supporting blocks 22, the furnace door 200 is supported and the base 10 is moved. The base 10 drives the furnace door 200 to move to the bottom of the furnace tube under the action of the moving wheels, and the frame 21 is raised by the lifting member 30. The furnace door 200 is raised to the same height as the furnace tube and aligned with the installation arm of the furnace tube. The furnace door 200 and the installation arm are connected by bolts to complete the installation of the furnace door 200. Finally, the furnace door 200 auxiliary device 100 is removed.

[0037] When the furnace door 200 is disassembled, the frame 21 is raised by the lifting member 30 so that the bottom of the furnace door 200 contacts the two supporting blocks 22. The furnace door 200 is supported and the bolts are removed. The base 10 is moved to complete the disassembly of the furnace door 200.

[0038] In some embodiments, the support block 22 is made of a soft material. The support block 22 is made of polyurethane, which has good softness and can protect the oven door 200 and prevent the oven door 200 from being damaged.

[0039] In some embodiments, the base 10 , the frame 21 , the lifting member 30 and the guide member 40 are all made of metal and have good rigidity and can bear the weight of the oven door 200 .

[0040] In some embodiments, the moving wheel is a universal wheel.

[0041] In some embodiments, the spacing direction of the two supporting blocks 22 is configured as a first direction X. The direction in which the furnace door 200 rises or falls is configured as a vertical direction Z. The center 200a of the furnace door is parallel to the vertical direction Z.

[0042] See also Figure 3 In some embodiments, the lifting member 30 includes a screw rod 31 and a nut 32 connected to each other. The screw rod 31 is rotatably connected to the base 10 and extends in the vertical direction Z. The nut 32 is fixedly connected to the frame 21. The screw rod 31 rotates relative to the base 10, causing the nut 32 to drive the frame 21 to rise or fall in the vertical direction Z, thereby raising or lowering the furnace door 200.

[0043] In some embodiments, the auxiliary device 100 further includes a guide member 40. The guide member 40 is fixedly connected to the base 10. The guide member 40 is disposed through the frame 21 and is capable of sliding relative to the frame 21. The guide member 40 extends in the vertical direction Z to guide the frame 21 in the vertical direction Z. The guide member 40 guides the movement of the frame 21, preventing the frame 21 from swinging or shaking during the lifting process, ensuring stable lifting and lowering.

[0044] In some embodiments, the guide member 40 includes two guide rods 41. The two guide rods 41 are respectively provided on opposite sides of the screw rod 31 along the first direction X, and can support both ends of the frame 21 along the first direction X, making the frame 21 more stable during the lifting process.

[0045] See also Figure 3 and Figure 4 The guide rod 41 and the screw rod 31 are respectively arranged on opposite sides of the support block 22 along the second direction Y, and can support both ends of the frame 21 along the second direction Y, so that the frame 21 can bear the weight of the furnace door 200 and drive the furnace door 200 to rise and fall smoothly.

[0046] In some embodiments, the first direction X and the second direction Y are two perpendicular horizontal directions, wherein the horizontal direction is perpendicular to the vertical direction Z.

[0047] In some embodiments, the lifting member 30 is configured as an electric lifting member 30 , and the lead screw 31 is coaxially connected to the motor to drive the lead screw 31 to rotate.

[0048] See also Figures 1 to 4In some embodiments, the lifting member 30 is configured to adjust the lifting of the frame 21 through the adjusting member 50. The adjusting member 50 is connected to the screw rod 31. The adjusting member 50 is used to drive the screw rod 31 to rotate. The rotation of the screw rod 31 can cause the nut 32 to drive the frame 21 to rise or fall.

[0049] By adjusting the height of the frame 21 through the adjusting member 50 , the operator can conveniently operate the frame 21 while observing the height of the furnace door 200 , thereby preventing the furnace door 200 from being raised or lowered too high or too low.

[0050] In some embodiments, the adjustment member 50 is a forward / reverse ratchet adjustment bolt. When the forward / reverse ratchet adjustment bolt is set to the clockwise direction to raise the frame 21, driving the screw 31 clockwise causes the frame 21 to rise. Rotating it counterclockwise prevents the screw 31 from rotating, allowing the adjustment member 50 to rotate back to its original position. This prevents the adjustment member 50 from interfering with the frame 21 or the oven door 200, resulting in adjustment failure. Conversely, when the forward / reverse ratchet adjustment bolt is set to the counterclockwise direction to lower the frame 21, driving the screw 31 counterclockwise causes the frame 21 to descend. Rotating it clockwise prevents the screw 31 from rotating, allowing the adjustment member 50 to rotate back to its original position. Thus, the forward / reverse ratchet adjustment bolt provides a greater adjustment range and flexibility.

[0051] In some embodiments, the adjusting member 50 is coaxially and fixedly connected to the screw rod 31, which is convenient for the operator to adjust at any time to prevent the adjusting member 50 from being lost. In addition, the adjusting member 50 can also be detachably connected to the screw rod 31, which is not limited here.

[0052] See also Figure 3 and Figure 4 In some embodiments, the frame 21 includes a flat plate 211 and two inclined plates 212. The two inclined plates 212 are respectively connected to the two ends of the flat plate 211. The flat plate 211 extends along a first direction. The extension direction of the inclined plates 212 forms a first angle α with the extension direction of the flat plate 211. The first angle α is an obtuse angle, so that the two inclined plates 212 can adapt to the outer periphery of the disc-shaped furnace door 200. Each inclined plate 212 is connected to a support block 22 at one end away from the flat plate 211, so that the two support blocks 22 support the furnace door 200, thereby spacing the furnace door 200 from the frame 21 (see Figure 2 ). See Figure 2 When the two supporting blocks 22 support the furnace door 200, the furnace door 200 has two supporting points. The setting of the first angle α enables the two supporting blocks 22 to provide a clamping force for the furnace door 200, which can prevent the furnace door 200 from rolling relative to the frame 21 along the first direction X.

[0053] In some implementations, the inclined plate 212 is connected to the center of the flat plate 211 along the second direction Y, so that the frame 21 is more stable when the supporting block 22 supports the furnace door 200 .

[0054] See also Figure 3 and Figure 4 In some embodiments, the base 10 includes a bottom plate 12, two connecting members 13, and two mounting members 14. The two connecting members 13 are respectively connected to both ends of the bottom plate 12. One end of each connecting member away from the bottom plate 12 is connected to a mounting member 14.

[0055] See also Figure 4 The bottom plate 12 extends in a first direction, thereby adapting to the shape of the flat plate 211. The mounting member 14 extends in the first direction to facilitate the installation and fixation of the movable wheel. The extension direction of the connecting member 13 forms a second angle β with the extension direction of the bottom plate 12. This second angle β is obtuse, thus adapting to the shape of the inclined plate 212. Thus, the base 10 is adapted to the shape of the frame 21, making the overall structure of the furnace door 200 auxiliary device 100 compact.

[0056] In some embodiments, the connector 13 has a hollow portion 101. The support block 22 and the inclined plate 212 are located directly above the hollow portion 101. When the inclined plate 212 is deformed under the pressure of the furnace door 200 under special circumstances, the inclined plate 212 and the support block 22 can pass through the hollow portion 101 to prevent the frame 21 from colliding with the base 10.

[0057] In some embodiments, the bottom plate 12 is larger than the flat plate 211, thereby providing sufficient support for the flat plate 211. The first angle α is greater than the second angle β, thereby increasing the distance between the bottom plate 12 and the support block 22, preventing the inclined plate 212 from deforming under special circumstances and being on the same level as the flat plate 211, so that the inclined plate 212 directly passes through the hollow portion 101 and contacts the ground.

[0058] In some embodiments, the connector 13 includes two ribs 131. The two ribs 131 are connected to the base plate 12 at intervals along the second direction Y. The mounting member 14 includes two connecting blocks 141 for mounting the movable wheels, thereby providing the base 10 with four movable wheels at the bottom, thereby facilitating stable movement of the base 10. Each rib 131 is connected to a connecting block 141 at one end away from the base plate 12, so that the base plate 12, the two ribs 131, and the two connecting blocks 141 form a hollow portion 101.

[0059] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
