Description

Technical Field

[0001] The utility model relates to the technical field of electric heating, in particular to a vacuum evaporation source heating component. Background Art

[0002] During the use of the coating equipment, the coating raw materials need to be vacuum evaporated and heated, so a vacuum evaporation source heating component is required.

[0003] For example, the patent publication number CN210560695U is a vacuum evaporation source heating component, which is placed outside the insulating shell through a wire. The insulating shell is provided with a groove reserved for fixing the heating wire and connecting the wire. The evaporation source heating wire is covered with an insulating shell, and the heating wire is sealed in the insulating shell. When heating, the heating wire can maintain its status and heat stably and evenly, preventing deformation at high temperature and causing a short circuit.

[0004] However, in actual use of the above-mentioned vacuum evaporation source heating assembly, since the entire device is completely heated by the heating wire, when a certain part of the heating wire is damaged, the entire heating wire needs to be replaced, which increases the maintenance cost of the device. For this reason, the applicant proposes a vacuum evaporation source heating assembly. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum evaporation source heating component to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum evaporation source heating component, comprising two protective shells, the opposite surfaces of the two protective shells are respectively threadedly clamped with heating mechanisms, the heating mechanisms include two heat-conducting sleeves, the opposite surfaces of the two heat-conducting sleeves are respectively fixed with a plurality of heat transfer frames, a plurality of copper rods are fixed between the two groups of heat transfer frames, a plurality of heat-conducting rods are respectively fixed on both sides of the copper rods, and the opposite ends of the two adjacent groups of heat-conducting rods are commonly fixed with uniformly distributed rods.

[0007] Preferably, the height of the uniformly distributed rod is smaller than the height of the copper rod, and is larger than the sum of the heights of each group of heat-conducting rods.

[0008] Preferably, the inner walls of the two heat-conducting sleeves are respectively provided with a plurality of grooves, and the opposite surfaces of the plurality of grooves are in contact with the heating wire.

[0009] Preferably, the length of the heating wire is greater than the length of the heat-conducting sleeve.

[0010] Preferably, a plurality of the copper rods and a plurality of groups of heat-conducting rods are clamped with a plurality of heat-absorbing strips on one side, a heat-conducting drum is clamped with a heat-conducting drum on one side of the outer walls of the two heat-conducting sleeves, and the outer wall of the heat-conducting drum is fixed to a plurality of heat-absorbing strips on one side.

[0011] Preferably, the other sides of the outer walls of the two heat-conducting sleeves are commonly clamped with an outer shell, and the top and bottom of the outer wall of the outer shell are respectively threadedly clamped with the opposite surfaces of the two protective shells.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The vacuum evaporation source heating component has a heating mechanism, in which a heat-conducting sleeve and a heat-transfer frame are added. The heat-conducting sleeve can absorb the heat of the heating wire and transfer it to the heat-transfer frame. The heat-transfer frame absorbs the heat of the heat-conducting sleeve through a plurality of heat-transfer frames, and the absorbed heat is concentratedly transferred to one end of the heat-conducting frame, thereby improving the thermal conductivity of the device and reducing the cost of maintaining and replacing the heating wire.

[0014] At the same time, heat conducting rods and dispersion rods are installed in the heating mechanism. The heat conducting rods can disperse the heat on the copper rods. At the same time, the dispersion rods will absorb the heat from several heat conducting rods and transfer the heat evenly to several heat conducting rods again, thereby improving the heating uniformity of the device and further reducing the cost of maintenance and replacement of the heating wire.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] When coating various products with coating equipment, the coating raw materials need to be vacuum evaporated and heated, so a vacuum evaporation source heating component is needed. Most traditional vacuum evaporation source heating components are assembled using a large number of heating wires during actual use to achieve the purpose of heating the device. However, when the performance of the heating wire is reduced due to long-term operation, or a certain part is damaged, the heating wire of the entire device needs to be replaced, which increases the maintenance cost of the device. For this reason, the applicant proposes a vacuum evaporation source heating component.

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a vacuum evaporation source heating component, comprising two protective shells 1, the two protective shells 1 are respectively threaded with heating mechanisms 2, the heating mechanism 2 comprises two heat-conducting sleeves 201, the two heat-conducting sleeves 201 are respectively fixed with a plurality of heat-conducting frames 202 on the opposite surfaces, a plurality of copper rods 203 are fixed between the two groups of heat-conducting frames 202, a plurality of heat-conducting rods 204 are respectively fixed on both sides of the copper rods 203, and the opposite ends of the two adjacent groups of heat-conducting rods 204 are commonly fixed with uniformly distributed rods 205, and the height of the uniformly distributed rods 205 is less than the height of the copper rods 203, and is greater than the sum of the heights of each group of heat-conducting rods 204. And, the inner walls of the two heat-conducting sleeves 201 are respectively provided with a plurality of grooves 206, and the opposite surfaces of the plurality of grooves 206 are in contact with a heating wire 207, the length of the heating wire 207 is greater than the length of the heat-conducting sleeve 201, and a plurality of copper rods 203 and a plurality of groups of heat-conducting rods 204 are clamped with a plurality of heat-absorbing strips 208 on one side, and a heat transfer reel 209 is clamped with one side of the outer walls of the two heat-conducting sleeves 201, and the outer wall of the heat transfer reel 209 is fixed to one side of the plurality of heat-absorbing strips 208, and the other side of the outer walls of the two heat-conducting sleeves 201 is clamped with a shell 210, and the top and bottom of the outer wall of the shell 210 are respectively threadedly clamped with the opposite surfaces of the two protective shells 1.

[0023] It should be noted that during the use of the device, firstly, the heat absorbing strips 208 on the outer wall of the heat transfer roll 209 are clamped onto the copper rods 203 and the heat conducting rods 204. Then, the top and bottom of the outer wall of the heat transfer roll 209 are clamped onto the two heat conducting sleeves 201. Then, the two heating wires 207 are passed through the inside of the two heat conducting sleeves 201, and the two ends of the heating wires 207 are pulled out and connected to the terminals. Then, the top and bottom of the inner wall of the protective shell 1 and the other ends of the two heat conducting sleeves 201 are clamped onto the outer wall of the protective shell 1. The two sides are clamped to each other, and then the protective shell 1 is threadedly clamped to the top and bottom of the shell 210, and then the device is installed at the evaporation source. Then, the terminal is started to make the two heating wires 207 perform heating operation. The heat of the heating wires 207 will first be absorbed by the heat-conducting sleeve 201. Because the multiple grooves 206 set on the inner wall of the heat-conducting sleeve 201 can increase the heat absorption area of ​​the heat-conducting sleeve 201, the heat of the heat-conducting sleeve 201 will be absorbed by the multiple heat transfer frames 202, and the multiple heat transfer brackets of the heat transfer frame 202 will absorb the heat. The collected heat is concentratedly transferred to one end of the heat transfer frame 202 and transferred to the copper rod 203. Subsequently, several groups of heat-conducting rods 204 absorb the heat from the copper rod 203. When a heat-conducting rod 204 at a certain location is not heated in time due to the height of the device being too high or other reasons, the evenly dissipating rod 205 transfers the heat absorbed from other heat-conducting rods 204 to the heat-conducting rod 204 at that location, thereby accelerating the uniformity of the heat dissipation of the device. At the same time, several copper rods 203 and several groups of heat-conducting rods 204 transfer the heat to several heat-absorbing rods 204. 208, the heat transfer reel 209 will absorb the heat from the several heat absorbing strips 208. When maintaining the device, it is only necessary to detach the two heat-conducting sleeves 201 from the clamping joints with the outer shell 210, and detach the heat transfer reel 209 and the two heat-conducting sleeves 201 and the clamping joints between the several copper rods 203 and the several groups of heat-conducting rods 204, so as to complete the disassembly and maintenance operations of the device. The two protective shells 1 can protect the heat-conducting sleeves 201 from direct contact with the outside world, thereby improving the cleanliness and service life of the heat-conducting sleeves 201.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
