Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a separate double-leveling heating device. Background Art

[0002] Most existing heating devices use a pallet that lifts the material to a designated position, heating the material while clamping it up and down at the designated position to ensure good heating efficiency. However, when the pallet is heavy, it is prone to deformation, resulting in uneven adhesion of the material, which in turn causes poor heating of the material in the unevenly adhered position. In addition, the existing heating platform is tightly connected to other structures. The heat radiation from the heating platform can cause deformation of surrounding parts, rapidly reducing the accuracy of the heating device. This is especially true for the cylinders around the heating platform that drive the pallet up and down, as well as the linear bearings and guide rods that guide the pallet. These components are prone to deformation due to their close proximity to the heating platform, which has a certain impact on the pallet's guidance accuracy. Utility Model Content

[0003] The purpose of the utility model is to provide a separate double-leveling heating device, which mainly solves the technical problem of how to ensure the reliability of heating a large surface of the material and improve the stability of the use of the heating device.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

The plurality of first leveling mechanisms are used to jointly support the heating platform relative to the base and jointly adjust the parallelism of the heating platform relative to the base.

[0007] The pressing mechanism includes a driver, a lifting seat, and a pressing plate connected in sequence. The driver is connected to the base and is used to drive the lifting seat and the pressing plate to move together in the vertical direction. A plurality of second leveling mechanisms are connected between the lifting seat and the pressing plate. The plurality of second leveling mechanisms are used to jointly support the pressing plate relative to the lifting seat and jointly adjust the parallelism of the pressing plate relative to the heating platform. The pressing plate is located above the heating platform, and the descent of the pressing plate is used to clamp the material together with the heating platform.

[0008] In one of the technical solutions, the first leveling mechanism includes a connected support rod and a pad located at the upper end of the support rod, the support rod is fixed on the base, the height of the pad relative to the support rod is adjustable, and the heating platform is simultaneously connected to multiple pads of the first leveling mechanism.

[0009] In one technical solution, the second leveling mechanism includes a pad block, a first adjustment block, a second adjustment block and a screw;

[0010] The screw passes through the pressure plate, the first adjusting block, the second adjusting block, and the raising block in sequence and is threadedly connected to the lifting seat. The first adjusting block is threadedly connected to the second adjusting block, and when the first adjusting block is rotated, the second adjusting block moves closer to or away from the first adjusting block in the vertical direction.

[0011] In one of the technical solutions, the heating platform includes a heating body and a heater and a temperature sensor connected to the heating body. The heating body is provided with a working surface for carrying materials, and the working surface is used to clamp the material together with the pressing plate. The heater is used to heat the heating body, and the temperature sensor is used to detect the temperature of the heating body. The temperature sensor is connected to the heater signal.

[0012] In one of the technical solutions, the heating platform includes multiple groups of heating components connected to the heating body, and each group of heating components includes a pair of temperature sensors and heaters that are signal-connected to each other.

[0014] In one of the technical solutions, a plurality of adsorption holes for adsorbing materials are provided on the working surface, and a plurality of air outlet holes for spraying protective gas are also provided on the working surface.

When the pressing plate and the working surface jointly clamp the material, the upper surface of the pressing plate is higher than the working surface, and the cover plate is opposite to the working surface and a gap is left between the cover plate and the working surface, so that the working surface, the pressing plate and the cover plate are jointly enclosed to form a chamber.

[0015] In one of the technical solutions, two pressing plates are connected to the lifting seat, and both of the pressing plates are used to clamp the material together with the heating platform, and the opposite sides of the two pressing plates are both blocking surfaces for limiting the deviation of the material.

Moreover, the multiple second leveling mechanisms are also used to jointly adjust the parallelism of the pressure plate relative to the heating platform to ensure that the material can be flatly attached to the heating platform over a large area after the pressure plate presses down on the material, so as to improve the quality of large-surface heating of the material.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Please also refer to Figures 1 to 5This embodiment provides a separate, dual-leveling heating device, comprising a base 1, a heating platform 2, and a material pressing mechanism 3. The material pressing mechanism 3 specifically comprises a driver 31, a lifting seat 32, and a pressing plate 33, which are connected in sequence. The heating platform 2 is used to carry the material and heat it to a specified temperature. The driver 31 is used to drive the lifting seat 32 and the pressing plate 33 to move vertically together. The pressing plate 33 is located above the heating platform 2. When the pressing plate 33 descends, it is used to clamp the material together with the heating platform 2, so that the material is flatly attached to the heating platform 2 over a large area. Compared with the traditional method of pressing the material upward with a support plate, the method of pressing the material downward with the pressing plate 33 in this solution can better ensure the reliability of the material being flatly attached to the heating platform 2. The driver 31 is preferably a low-cost single-axis cylinder, and the lifting seat 32 is preferably connected to the base 1 via a cross-roller guide 34 to improve the accuracy of the vertical movement of the lifting seat 32 and the pressing plate 33.

[0032] In this embodiment, a plurality of first leveling mechanisms 4 are connected between the base 1 and the heating platform 2. The plurality of first leveling mechanisms 4 are used to jointly support the heating platform 2 relative to the base 1, so that the distance between the heating platform 2 and the external components is farther, and the components outside the heating platform 2 are prevented from being subjected to excessive heat radiation, thereby ensuring that the components outside the heating platform 2 can still maintain better accuracy after long-term use, and ensuring that the heating device still has better stability after long-term work. Since the heating platform 2 is supported, the first leveling mechanism 4 is also used to adjust the parallelism of the heating platform 2 relative to the base 1, ensuring the stability of the heating platform 2 horizontally supporting the material. In addition, this solution also A plurality of second leveling mechanisms 35 are connected between the lifting seat 32 and the pressing plate 33. The plurality of second leveling mechanisms 35 are used to jointly support the pressing plate 33 relative to the lifting seat 32 to prevent the components outside the pressing plate 33 from being subjected to excessive heat radiation, thereby ensuring that the components outside the pressing plate 33 can maintain good precision after long-term use, and further ensuring that the heating device still has good stability after long-term operation. Moreover, the plurality of second leveling mechanisms 35 are also used to jointly adjust the parallelism of the pressing plate 33 relative to the heating platform 2 to ensure the reliability of the material being able to fit flatly on the heating platform 2 over a large area after the pressing plate 33 presses down the material, so as to improve the quality of large-surface heating of the material.

[0033] In this embodiment, the first leveling mechanism 4 specifically includes a connected support rod 41 and a pad 42. The pad 42 is located at the upper end of the support rod 41. The heating platform 2 is simultaneously connected to the pads 42 of multiple first leveling mechanisms 4. The support rod 41 is fixed on the base 1. The pad 42 holds the support rod 41 in a clamping manner. The height position of the pad 42 is adjusted by the height at which it is clamped on the support rod 41. By adjusting the height position of the pad 42 on each first leveling mechanism 4, the parallelism of the heating platform 2 relative to the base 1 can be adjusted.

[0034] In this embodiment, the second leveling mechanism 35 specifically includes a padding block 351, a first adjusting block 352, a second adjusting block 353 and a screw (not shown in the figure), wherein the screw passes through the pressure plate 33, the first adjusting block 352, the second adjusting block 353 and the padding block 351 in sequence and is locked on the lifting seat 32. The padding block 351 is used to pad the pressure plate 33 higher to solve the problem of excessive heat radiation from the pressure plate 33 to the components below. The first adjusting block 352 is threadedly connected to the second adjusting block 353 so that when the first adjusting block is rotated, the second adjusting block 353 is screwed to the first adjusting block 351. 352, the second adjusting block 353 can be close to or away from the first adjusting block 352 in the vertical direction. By rotating the first adjusting block 352 on each second leveling mechanism 35 respectively, the parallelism of the pressing plate 33 relative to the heating platform 2 can be adjusted; in addition, the top surface of the lifting seat 32 is provided with an adjusting groove 321, and a nut for screw locking can be placed in the adjusting groove 321. By sliding the nut in the adjusting groove 321, the position of the entire second leveling mechanism 35 can be adjusted, thereby being compatible with the clamping of products of different widths.

[0035] Most existing heating platforms are structures in which a working surface and a heating body are integrated. In order to ensure the accuracy and strength of the heating platform, the thermal conductivity of the material used is not high, and it has the disadvantages of slow heating and uneven temperature. This will cause uneven heating of the material, affect the subsequent welding process, and cause poor welding. In this regard, the present solution specifically designs the heating platform 2 as a separate heating body 21, a heater 22, and a temperature sensor 23, wherein the heater 22 is used to heat the heating body 21, and a working surface 211 is provided on the heating body 21. This working surface 211 is used to carry the material and directly heat the material. When heating, the working surface 211 will clamp the material together with the above-mentioned pressing plate 33 so that the material can be attached to the working surface 211 over a large area when heated, and the temperature sensor 23 is used to detect the temperature of the heating body 21. The temperature sensor 23 is connected to the heater 22 signal. The heater 22 adjusts the heat of the heating body 21 in real time according to the actual temperature data fed back by the temperature sensor 23, so that the temperature of the heating body 21 is more accurate. This solution can improve the heating efficiency of the heating body 21 by splitting the heating platform 2 into a heating body 21 and a plurality of heaters 22 .

[0036] Specifically, the heating platform 2 of this embodiment includes multiple groups of heating components 20 connected to a heating body 21. Each group of heating components 20 includes a pair of temperature sensors 23 and heaters 22 that are signal-connected to each other. By providing multiple independently controlled heating components 20, the problem of uneven heating of the working surface 211 is resolved, allowing the working surface 211 to heat the material more evenly over a large area under the heating of multiple independent heating components 20. To improve the heating efficiency and temperature accuracy of the heating body 21, the heaters 22 in all heating components 20 of this embodiment are in surface contact with the heating body 21.

[0037] In this embodiment, a plurality of adsorption holes 2111 are provided on the working surface 211. The adsorption holes 2111 are used to adsorb the material, so that the material is more tightly attached to the working surface 211, while also preventing the material from shifting on the working surface 211. In addition, a plurality of air outlet holes 2112 are provided on the working surface 211 for ejecting a shielding gas (such as nitrogen or helium). The pressing mechanism 3 also includes a cover plate 36 connected to the pressing plate 33. When the pressing plate 33 and the working surface 211 jointly clamp the material, the upper surface of the pressing plate 33 is higher than the working surface 211, and the cover plate 36 faces the working surface 211 with a gap between them. This allows the working surface 211, the pressing plate 33, and the cover plate 36 to jointly form a chamber. This chamber allows the shielding gas to remain for a period of time, preventing it from rapidly flowing out. The shielding gas is used to protect the material and prevent oxidation of the material after prolonged heating.

[0038] In this embodiment, two pressure plates 33 are connected to the lifting seat 32. Both pressure plates 33 are used to clamp the material together with the heating platform 2. The opposite sides of the two pressure plates 33 are both blocking surfaces 331 for limiting the deviation of the material. When the material enters or moves out, the blocking surfaces 331 on the two pressure plates 33 can guide the material, solving the problem of the material running off in the process of gradually entering the heating platform 2 or gradually leaving the heating platform 2.

[0039] The above is merely a preferred embodiment of the present invention and only specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be imagined by those skilled in the art without inventive effort, shall be included within the scope of protection of the present invention.
