[0001] The utility model relates to the field of composite material devices, in particular to a device for depositing copper-based composite materials. Background Art
[0002] As a commonly used metal material, copper has limited application scope due to its low strength. Graphene has excellent comprehensive properties and has attracted widespread attention as a highly potential reinforcement. Graphene-reinforced copper-based composites have the excellent properties of both copper and graphene and have become an important research object; the chemical vapor deposition method uses polymethyl methacrylate (PMMA) or carbon-containing organic matter such as methane as a carbon source, and directly generates graphene on the surface of copper-based metal under certain reaction conditions to obtain a composite powder or graphene film, and then sintering to obtain a composite material. By adjusting the deposition parameters of the chemical vapor deposition method, a high-quality graphene reinforcement with a controllable number of layers can be prepared. The graphene has a large two-dimensional plane size and is well bonded to the base metal, which is conducive to the composite material obtaining higher electrical and thermal conductivity;
[0003] In the prior art, a deposition furnace is generally used to sinter the composite powder. However, the existing deposition furnace uses an integrated heater. Once the integrated heater is cracked, the entire heater will no longer be usable, which increases the production cost. In order to solve the problems existing in the prior art, a utility model with publication number CN219731055U discloses a ring heater for a deposition furnace (hereinafter referred to as: prior art 1), which is characterized in that it includes a heating rod, an upper connecting ring, a lower connecting ring and a graphite electrode, the upper connecting ring and the lower connecting ring are respectively composed of a group of circumferentially arranged graphite bent plates, and gaps are left between the graphite bent plates at the ends; the graphite bent plates in the upper connecting ring are staggered with the graphite bent plates in the lower connecting ring; the heating rods are a group, and their upper and lower ends are respectively fixed on the upper connecting ring and the lower connecting ring, thereby forming a heater with a cylindrical shape as a whole; the graphite electrode is connected to two separated graphite bent plates on the upper connecting ring.
[0004] Although the prior art 1 provides a ring heater that is easy to disassemble and assemble, in the prior art, since both ends of the heating rod are fixed between the upper connecting ring and the lower connecting ring by bolts, the heating rod will expand due to heat, which may cause cracks or breakage in the heating rod. Utility Model Content
[0005] The purpose of the utility model is to provide a device for depositing copper-based composite materials, which, in actual use, can solve the problem in the prior art that when both ends of a heating rod are fixed between an upper connecting ring and a lower connecting ring by bolts, the heating rod expands due to heat, which may cause cracks or breakage in the heating rod.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0007] A device for depositing a copper-based composite material, comprising a vapor deposition furnace and a graphite electrode for connecting to a water-cooled electrode of the vapor deposition furnace, and further comprising:

[0010] A lower mounting ring, wherein the lower mounting ring is provided with a positioning groove for positioning an end of the heating rod away from the upper mounting ring, and the lower positioning ring is connected to the graphite electrode;
[0011] Wherein, a moving component is slidably installed in the positioning groove, and the moving component is used to press against the outer surface of the end of the heating rod away from the upper mounting ring.
[0012] Preferably, the heating rod is cylindrical with a thick middle and thin ends.

[0014] Preferably, the moving assembly includes a moving part and a spring, the moving part is slidably installed in the positioning groove, and the moving part and the positioning groove are connected by the spring.
[0015] Preferably, a ball cavity is provided on the moving part, and a ball is rotatably installed in the ball cavity.
[0016] Preferably, one end of the graphite electrode is provided with a threaded hole for cooperating with the water-cooled electrode, and the other end of the graphite electrode is connected to the upper mounting ring and the lower mounting ring through bolts.
[0017] Preferably, the upper mounting ring and the lower mounting ring are both connected to support rods, and the upper mounting ring and the lower mounting ring are connected to the meteorological deposition furnace through the support rods.
[0018] Preferably, the support rods are all made of carbon steel.

[0021] Compared with the prior art, the utility model has the following beneficial effects:
[0022] In the utility model, the graphite electrode is connected with the water-cooled electrode to form a loop.

When the heating rod is damaged, the heating rod can be disassembled and a single component can be replaced, thereby reducing maintenance costs. The other end of the heating rod is slidably installed in the positioning groove, so that the heating rod will not be broken due to the compression between the heating rod and the lower mounting ring during the heating process due to thermal expansion, thereby increasing the service life of the heating rod.
[0024] During the expansion of the heating rod, the moving component that is slidably installed in the positioning groove and arranged vertically to the heating rod is always pressed against the side of the heating rod. While ensuring that the current in the lower mounting ring can be distributed to the heating rod to ensure the heating effect, the moving component can also further limit the heating rod after the heat expansion.

[0037] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0038] Example
[0039] See also Figure 1-Figure 3 The present embodiment discloses a device for depositing copper-based composite materials, and specifically discloses a heating device for a vapor deposition furnace, including a vapor deposition furnace and a graphite electrode 101 for connecting to a water-cooled electrode of the vapor deposition furnace, and also includes a heating rod 102, an upper mounting ring 103 and a lower mounting ring 104, wherein the heating rod 102 is used to heat a reaction chamber arranged in the vapor deposition furnace; the upper mounting ring 103 is detachably connected to the heating rod 102, and the upper mounting ring 103 is connected to the graphite electrode 101; a positioning groove 105 is provided on the lower mounting ring 104 for positioning one end of the heating rod 102 away from the upper mounting ring 103, and the lower positioning ring is connected to the graphite electrode 101; wherein a moving component 106 is slidably installed in the positioning groove 105, and the moving component 106 is used to press against the outer surface of the end of the heating rod 102 away from the upper mounting ring 103.
[0040] In this embodiment, the graphite electrode 101 is connected to the water-cooled electrode to form a circuit. The current introduced by the graphite electrode 101 is evenly distributed to the heating rod 102 after passing through the upper mounting ring 103 and the lower mounting ring 104, which can make the heating rod 102 heat up and achieve heating of the thermal field in the deposition furnace. One end of the heating rod 102 is detachably connected to the upper mounting ring 103. When the heating rod 102 is damaged, the heating rod 102 can be disassembled and the individual components can be replaced, thereby reducing maintenance costs; the other end of the heating rod 102 is slidably installed in the positioning groove 105, so that the heating rod 102 will not break due to the compression between the heating rod 102 and the lower mounting ring 104 during the heating process, thereby increasing the service life of the heating rod 102; during the expansion process, the heating rod 102 is slidably installed in the positioning groove 105. 5 and the movable assembly 106 vertically arranged with respect to the heating rod 102 is always pressed against the side of the heating rod 102, and while ensuring that the current in the lower mounting ring 104 can be distributed to the heating rod 102 to ensure the heating effect, the movable assembly 106 can also further limit the heating rod 102 after the heating expansion; the upper mounting ring 103, the lower mounting ring 104 and the heating rod 102 in this embodiment are made of graphite, and the number and length of the heating rods 102 can be adjusted according to the space of the thermal field in the deposition furnace and the requirements of the heating temperature.
[0041] Specifically, the heating rod 102 is cylindrical and thick in the middle and thin at both ends. During the process of heating the materials in the vapor deposition furnace by the heating rod 102, since the middle area of the vapor deposition furnace is the heating temperature concentration area, the temperature in the furnace cavity gradually decreases from the middle to the surroundings, and the temperature uniformity of the thermal field is poor; by setting the cylindrical heating rod 102 with a thick middle and thin ends, the difference in the diameter of the heating rod 102 can be used to achieve resistance compensation, so that the heating temperature at both ends of the heating rod is higher than the heating temperature in the middle position, solving the problem of temperature decreasing from the middle heating area to the surroundings.
[0042] Specifically, the lower mounting ring 104 is provided with a clearance groove 107, which is coaxially arranged with the positioning groove 105 and communicated with the positioning groove 105. The diameter of the clearance groove 107 is larger than the diameter of the middle end of the heating rod 102. By providing the clearance groove 107, the middle end of the heating rod 102 that has expanded due to heat can be given way after moving downward, so as to prevent the middle section of the heating rod 102 from being squeezed and damaged by the lower mounting ring 104 after expansion.
[0043] Specifically, the moving assembly 106 includes a moving part 108 and a spring 109. The moving part 108 is slidably installed in the positioning groove 105, and the moving part 108 is connected to the positioning groove 105 through the spring 109. The moving part 108 and the spring 109 are both made of graphite material, and the moving part 108 is always in contact with the positioning groove 105 during the sliding process; before the heating rod 102 is heated and expanded, the current in the lower mounting ring 104 is distributed to the heating rod 102 through the moving part 108 to ensure the heating effect. After the heating rod 102 is heated and expanded, the moving part 108 is squeezed, and the spring 109 connecting the moving part 108 and the positioning groove 105 is compressed. Under the action of the spring 109, it can be ensured that the moving part 108 is always in contact with the bottom end of the heating rod 102; there are multiple moving parts 108, and the multiple moving parts 108 are installed in the positioning groove 105 at equal intervals along the circumferential direction of the positioning groove 105.
[0044] Specifically, the moving part 108 is provided with a ball cavity, in which a ball 110 is rotatably mounted. The heating rod 102 will move downward during the process of thermal expansion, and the ball 110 can be provided to avoid the heating rod 102 and the moving part 108 from being damaged by large friction.
[0045] Specifically, one end of the graphite electrode 101 is provided with a threaded hole for matching with the water-cooled electrode, and the other end of the graphite electrode 101 is connected to the upper mounting ring 103 and the upper mounting ring 103 by bolts. By connecting the upper mounting ring 103 and the lower mounting ring 104 to the graphite electrode 101 by bolts, the upper mounting ring 103 or the lower mounting ring 104 can be easily replaced.
[0046] Specifically, the upper mounting ring 103 and the lower mounting ring 104 are both connected with support rods, and the upper mounting ring 103 and the lower mounting ring 104 are connected to the atmospheric deposition furnace through the support rods. The support rods can ensure the stability of the upper mounting ring 103 and the lower mounting ring 104 during use.
[0047] Specifically, the support rods are all made of carbon steel material. By using carbon steel material to make the support rods, the support rods can withstand a larger load and meet the high temperature use environment.
[0048] Specifically, the heating rods 102 are arranged at equal intervals along the circumferential direction of the upper mounting ring 103 and the lower mounting ring 104. By arranging the heating rods 102 at equal intervals, it can be ensured that the heating rods 102 can heat the materials in the furnace evenly.
[0049] Specifically, a resistance adjustment ring is sleeved on the outer side of the heating rod. The resistance adjustment ring is interference-fitted with the heating rod, and its diameter, length and position installed on the heating rod need to be determined according to the temperature in the graphene growth area during actual use. The resistance adjustment ring can change the local heating temperature of the heating rod, thereby realizing local temperature adjustment.
[0050] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
