[0037] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] refer to Figure 1 and Figure 2, an embodiment of the present application provides a loading platform for a thermal furnace, comprising: a support table 1, a rotating table 2, a first driving assembly 3, a pushing plate 4 and a pushing assembly 7. The support table 1 is the bottom supporting structure of the loading platform. The rotating table 2 is rotatably disposed on the support table 1. The first driving assembly 3 is disposed between the rotating table 2 and the support table 1, and is used to drive the rotating table 2 to rotate circumferentially relative to the support table 1. The pushing plate 4 is movably disposed on the rotating table 2, and is used to move horizontally relative to the rotating table 2 to deliver the workpiece placed thereon to the target position. The pushing assembly 7 is disposed on the pushing plate 4, and is used to push the workpiece out. When using the above-mentioned loading platform for loading, the workpiece to be processed can be placed on the pushing plate 4 first, and then the workpiece can be pushed into the furnace cavity of the thermal furnace by the pushing plate 4 and the pushing rod. Furthermore, since the turntable can rotate circumferentially relative to the support table 1, the pushing plate 4 can change the pushing direction when the turntable rotates, which enables the loading platform to adjust the pushing direction without moving, thereby making it convenient for the loading platform to load thermal furnaces in other positions, which is beneficial to improving convenience and work efficiency.

[0039] It should be noted that the workpiece recorded in the embodiments of the present application may be the workpiece itself to be processed, or may be a carrier loaded with the workpiece, such as a pallet.

[0040] In some embodiments, the support platform 1 includes a base 110 and a mounting seat 120. The mounting seat 120 is movably disposed on the upper surface of the base 110 and is used to mount the rotating platform 2, that is, the rotating platform 2 is rotatably disposed on the upper surface of the mounting seat 120. This arrangement allows the height of the rotating platform 2 to be adjustable, thereby adjusting the pushing height of the pushing plate 4, so that the loading platform can be suitable for loading thermal furnaces with different furnace mouth heights.

[0041] Furthermore, in order to realize the design of the mounting seat 120 being liftable, an electric telescopic rod 130 can be provided between the base 110 and the mounting seat 120, and the electric telescopic rod 130 is used to extend and retract to control the lifting and lowering of the mounting seat 120 relative to the base 110. In specific use, when the electric telescopic rod 130 is extended, the mounting seat 120 can be raised, and when the electric telescopic rod 130 is retracted, the mounting seat 120 can be lowered. In this way, the design of the mounting seat 120 being liftable can be realized, so that the pushing height of the pushing plate 4 can be adjusted, so that the loading platform can be suitable for loading thermal furnaces with different furnace mouth heights.

[0042] In some embodiments, a guide structure is provided between the rotating platform 2 and the mounting seat 120 to guide the rotating platform 2 when the rotating platform 2 rotates in a circumferential direction. This arrangement can ensure that the rotating platform 2 rotates smoothly and accurately and maintains good positioning accuracy.

[0043] In some embodiments, the guide structure includes an annular groove 121 and a slide bar 201. One of the annular groove 121 and the slide bar 201 is provided on the rotating table 2, and the other is provided on the mounting seat 120. The annular groove 121 and the slide bar 201 are slidably matched when the rotating table 2 rotates. Specifically, the annular groove 121 is provided on the upper surface of the mounting seat 120, and a plurality of slide bars 201 are evenly distributed on the lower surface of the rotating table 2 along the circumference thereof. In the assembled state, the slide bar 201 is inserted into the annular groove 121. When the rotating table 2 rotates, the plurality of slide bars 201 slide in the annular groove 121 to achieve the guiding effect on the rotating table 2. However, the embodiments of the present application do not make any limitation to this.

[0044] Further, in order to reduce the friction between the annular groove 121 and the slide bar 201, the slide bar 201 may be provided with a ball 202, which is used to contact the inner surface of the annular groove 121 and can rotate relative to the slide bar 201 when the rotating table 2 rotates. In other words, when the rotating table 2 rotates, the ball 202 and the inner surface of the annular groove 121 are rolled together. In this way, rolling friction can be used instead of sliding friction, which is conducive to reducing the friction between the annular groove 121 and the slide bar 201. In this embodiment, the ball 202 is located at the lower end of the slide bar 201, that is, when the rotating table 2 rotates, the ball 202 and the inner bottom surface of the annular groove 121 are rolled together to reduce the friction between the slide bar 201 and the inner bottom surface of the annular groove 121. Of course, in a specific implementation, the ball 202 can also be located at other positions of the slide bar 201, and this embodiment of the present application does not make any limitation.

[0045] In other possible embodiments, the slide bar 201 can rotate circumferentially relative to the rotating table 2. In this way, the sliding fit between the slide bar 201 and the inner side of the annular groove 121 can be converted into a rolling fit, thereby reducing the friction between the slide bar 201 and the inner side of the annular groove 121.

[0046] In some embodiments, the first driving assembly 3 includes a transmission shaft 301, a first gear 302, a second gear 303 and a motor 304. The transmission shaft 301 (the upper end thereof) is connected to the lower surface of the rotating table 2, and the axis of the transmission shaft 301 coincides with the axis of the rotating table 2. The first gear 302 is sleeved on the transmission shaft 301. The second gear 303 is rotatably disposed on the mounting seat 120 and meshes with the first gear 302. The motor 304 is disposed on the mounting seat 120 and is connected to the second gear 303 (through a coupling). In specific use, the second gear 303 can be driven to rotate circumferentially by starting the motor 304, and the first gear 302 can be driven to rotate circumferentially when the second gear 303 rotates, and the rotating table 2 can be driven to rotate circumferentially through the transmission shaft 301 when the first gear 302 rotates circumferentially, thereby realizing that the first driving assembly 3 drives the rotating table 2 to rotate circumferentially relative to the support table 1. However, the embodiments of the present application do not make any limitation to this.

[0047] Furthermore, in order to ensure the stability between the rotating table 2 and the mounting seat 120, the lower end of the transmission shaft 301 is rotatably connected to the mounting seat 120 through a bearing. In this way, the rotating table 2 and the mounting seat 120 can be connected through the transmission shaft 301, which is beneficial to improve the stability between the rotating table 2 and the mounting seat 120.

[0048] Further, in order to reduce the distance between the rotating platform 2 and the mounting seat 120 and lower the center of gravity, part or all of the parts of the first driving assembly 3 can be located in the groove 122 provided on the upper surface of the mounting seat 120. For example, in the assembled state, the transmission shaft 301, the first gear 302 and the second gear 303 of the first driving assembly 3 are located in the groove 122, and the motor 304 is located on the lower surface of the mounting seat 120.

[0049] In some embodiments, the mounting seat 120 is provided with an electric slide rail 5, and the push plate 4 is provided on the electric slide rail 5. When used, the electric slide rail 5 is activated to drive the push plate 4 to move linearly, thereby sending the workpiece placed thereon to the target position (inside the furnace chamber of the thermal furnace). It should be understood that, when specifically set, the movement direction of the electric slide rail 5 is consistent with the pushing direction of the push plate 4.

[0050] In some embodiments, the loading platform further includes at least two limit blocks 401, which are arranged relative to the push plate 4 and are used to limit the workpiece placed on the push plate 4. In this embodiment, the limit blocks 401 are L-shaped, and there are four limit blocks 401, which are respectively located at the four corners of the workpiece to limit the horizontal movement of the workpiece. This arrangement can ensure the position accuracy of the workpiece.

[0051] In some embodiments, a slide groove 402 is provided on the push plate 4, and at least two limit blocks 401 are slidably provided in the slide groove 402. In this embodiment, two slide grooves 402 parallel to each other are provided on the push plate 4, and two limit blocks 401 are provided in each slide groove 402. In specific use, the limit block 401 can slide in the slide groove 402 to adjust the distance and position of the limit block 401. In this way, the limit block 401 can move after the workpiece is placed to limit the workpiece. Compared with the fixed limit block 401, the operation of placing the workpiece on the push plate 4 is more flexible, and it can be applied to achieve the limit of workpieces of different sizes.

[0052] In some embodiments, the loading platform further includes a second driving assembly 6, which is disposed on the pushing plate 4 and connected to at least two limit blocks 401, and is used to drive at least two limit blocks 401 to slide toward or away from each other along the slide groove 402. In this way, it is convenient to realize automatic adjustment of the position of the limit block 401.

[0053] Furthermore, in order to realize automatic adjustment of the position of the limit block 401, the driving assembly includes two connecting plates 601, two racks 602, a toothed disc 603 and an electric push rod 604. The two connecting plates 601 are movably arranged on the push plate 4 and are respectively connected to at least two limit blocks 401. The two racks 602 are respectively connected to the two connecting plates 601. The toothed disc 603 is rotatably arranged on the push plate 4 and is respectively engaged with the two racks 602. The electric push rod 604 is arranged on the push plate 4 and is connected to one of the two connecting plates 601. In the specific setting, the two connecting plates 601 are respectively connected to two opposite limit blocks 401, that is, two limit blocks 401 located in the same slide groove 402. During use, by starting the electric push rod 604, the electric push rod 604 can move the connecting plate 601 connected thereto, and the connecting plate 601 can drive the limit block 401 connected thereto to slide in the slide groove 402 when moving. At the same time, the connecting plate 601 can also drive the rack 602 connected thereto to move, and the rack 602 can drive another rack 602 to move by cooperating with the toothed disc 603. When the other rack 602 moves, it can drive another connecting plate 601 to move, thereby driving another limit block 401 connected thereto to slide in the slide groove 402. In this way, the second drive assembly 6 can realize automatic adjustment of the position of the limit block 401, and the second drive assembly 6 only needs one electric push rod 604 to realize the position adjustment of the two limit blocks 401, thereby reducing the number of components used and saving installation space.

[0054] Further, in order to save space, the push plate 4 is provided with an assembly groove 403 connected to the slide groove 402, and some or all components of the second drive assembly 6 are arranged in the assembly groove 403. In this embodiment, the connecting plate 601, the rack 602 and the toothed disc 603 of the second drive assembly 6 are all arranged in the assembly groove 403 of the push plate 4, and the electric push rod 604 is arranged on the side of the push plate 4.

[0055] In some embodiments, the push assembly 7 includes a mounting plate 701 and a power push rod 702. The mounting plate 701 is arranged on the side of the push plate 4. The power push rod 702 is arranged on the mounting plate 701 and can move axially to push the workpiece out. It should be understood that in a specific implementation, the power push rod 702 can be an electrically or hydraulically driven push rod.

[0056] The method for using the loading platform for a thermal furnace in the embodiment of the present application includes:

[0057] 1. The first driving assembly 3 is controlled to make the rotating table 2 rotate in a circumferential direction until the pushing direction of the pushing plate 4 is consistent with the target direction.

[0058] 2. The height of the mounting seat 120 is adjusted by controlling the electric telescopic rod 130 until the pushing direction of the pushing plate 4 is aligned with the furnace opening of the target thermal furnace.

[0059] 3. Place the workpiece to be processed on the push plate 4, and control the second drive assembly 6 to move the limit block 401 until the limit block 401 abuts against the side of the workpiece.

[0060] 4. The push plate 4 is moved horizontally by controlling the electric slide rail 5 until the push plate 4 extends into the inner cavity of the thermal furnace.

[0061] 5. The second driving assembly 6 is controlled to move the limit block 401 away from the workpiece, so as to release the limit of the workpiece by the limit block 401.

[0062] 6. Push the workpiece on the pushing plate 4 out by controlling the pushing assembly 7 so that it falls onto the bracket in the thermal furnace.

[0063] The loading platform for the thermal furnace in the embodiment of the present application sets the pushing plate 4 on a rotating table that can rotate circumferentially. The pushing direction of the pushing plate 4 can be adjusted by controlling the circumferential rotation of the rotating table. This makes it possible to adjust the pushing direction without moving the loading platform, thereby making it convenient for the loading platform to load thermal furnaces in other orientations, which is beneficial to improving convenience and work efficiency.
