Description

Technical Field

[0001] This utility model relates to the field of vacuum sealing technology, and in particular to a graphite plate structure for high-temperature vacuum sealing that facilitates precise temperature detection and control. Background Technology

[0002] High-temperature vacuum sealing equipment is an advanced device that performs welding in a high-temperature and vacuum environment. It is mainly used to weld precision parts that need to be sealed in an oxygen-free and pollution-free environment. High-temperature vacuum sealing equipment sets a high temperature under vacuum conditions so that the product placed on the graphite plate can complete the melting of solder and mold closing. The temperature requirements are very high, and the accuracy of the temperature is also very strict. Therefore, the temperature detection system of the equipment must be accurate enough.

[0003] However, the current temperature measurement of the thermocouple temperature sensor and graphite plate in the equipment is limited by the contact-type indirect point temperature measurement, which leads to a certain slight error in the temperature of the graphite plate being detected. Therefore, those skilled in the art have provided a high-temperature vacuum sealing graphite plate structure that facilitates accurate temperature detection and control in order to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a graphite plate structure for high-temperature vacuum sealing that facilitates precise temperature detection and control. This structure allows the contact point of a thermocouple temperature sensor to be inserted into the graphite plate, enabling direct contact temperature measurement and achieving accurate temperature measurement, thus ensuring the accuracy of the sealing temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a graphite plate structure for high-temperature vacuum sealing welding that facilitates precise temperature detection and control, comprising a box body and a door, wherein the door is rotatably connected to the front end face of the box body, a bracket is fixedly connected to the center of the lower inner wall of the box body, a graphite plate is fixedly connected to the upper end face of the bracket, a groove is formed at one side of the center of the front end face of the graphite plate, a limiting groove is formed at the front of the groove, an installation groove is formed at the front of the limiting groove, and a detection structure is provided inside the groove;

[0006] The detection structure includes a thermocouple temperature sensor, which is slidably connected inside the groove. A limiting block is fixedly sleeved on the outer wall of the groove inside the limiting groove. Limiting plates are provided on both sides inside the mounting groove. Through holes are opened at the center of the adjacent end faces of the two limiting plates. The two through holes are sleeved on the outside of the thermocouple temperature sensor. Limiting screws are provided at the center of the front end faces of the two limiting plates.

[0007] Through the above technical solution, the contact point of the thermocouple temperature sensor can be inserted into the groove on the front end of the graphite plate, thereby realizing a direct contact temperature measurement method, which can achieve a direct and accurate temperature measurement effect, thus ensuring the accuracy of the sealing temperature.

[0008] Furthermore, a connecting rod is fixedly connected to the center of the front end face of the thermocouple temperature sensor, and a multi-stage conductive slip ring is sleeved on the end of the connecting rod;

[0009] By using the above technical solution, the connection between the device and the thermocouple temperature sensor is made possible by multi-stage conductive slip rings. This prevents damage to the connection wires due to angles at the connection points between the connection wires and the connecting rods, thus extending the service life of the device.

[0010] Furthermore, the fixed end of the multi-stage conductive slip ring is fixedly connected to the connecting rod, and the rotating end of the multi-stage conductive slip ring is fixedly connected to a spring connecting wire;

[0011] The above technical solution ensures that the connection via spring connecting wires will not affect installation and disassembly, and the spring connecting wires will not be scattered inside the enclosure after installation.

[0012] Furthermore, an observation window is fixedly connected to the center of the front end face of the box door;

[0013] The above technical solution facilitates observation of the internal situation.

[0014] Furthermore, the two limiting screws respectively penetrate the front end face of the two limiting plates and extend to the rear end of the two limiting plates, and their ends are threaded to the rear inner wall of the mounting groove;

[0015] The above technical solution uses two limiting screws that pass through the two limiting plates and are threaded onto the inner rear wall of the mounting groove, which facilitates installation.

[0016] Furthermore, both of the aforementioned limiting screws, the limiting block, and the limiting plate are all made of graphite;

[0017] Through the above technical solutions, graphite has excellent high-temperature stability and can maintain its physical and chemical properties unchanged in high-temperature environments. In high-temperature vacuum sealing equipment, the internal temperature of the equipment may reach thousands of degrees Celsius, and graphite can work normally at this high temperature without softening, deforming or decomposing.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the high-temperature vacuum sealing graphite plate structure, which facilitates precise temperature detection and control, allows the contact point of the thermocouple temperature sensor to be inserted into the groove on the front end of the graphite plate, thereby achieving a direct contact temperature measurement method. This results in a direct and accurate temperature measurement effect, ensuring the accuracy of the sealing temperature.

[0020] 2. In this utility model, during disassembly, two limiting screws are removed, and two limiting plates are taken out along with the two limiting screws. Then, the thermocouple temperature sensor is pulled out. During the removal and installation process, the connection through the spring connecting wire will not affect the installation and disassembly, and the spring connecting wire will not be scattered inside the box after installation.

[0021] 3. In this utility model, the device and the thermocouple temperature sensor are connected by a multi-stage conductive slip ring, which prevents damage to the spring connecting wire due to the angle at the connection position between the spring connecting wire and the connecting rod, thus improving the service life of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-4This utility model provides an embodiment of a high-temperature vacuum sealing graphite plate structure for easy and precise temperature detection and control, comprising a housing 1 and a door 4. The door 4 is rotatably connected to the front end face of the housing 1. A bracket 2 is fixedly connected to the center of the lower inner wall of the housing 1. A graphite plate 5 is fixedly connected to the upper end face of the bracket 2. A groove 8 is provided on one side of the center of the front end face of the graphite plate 5. A limiting groove 10 is provided at the front of the groove 8. An installation groove 6 is provided at the front of the limiting groove 10. A detection structure 9 is provided inside the groove 8. The detection structure 9 is set inside the groove 8 to fit the graphite plate 5 more closely for detection.

[0030] The detection structure 9 includes a thermocouple temperature sensor 901, which is slidably connected inside the groove 8. A limiting block 902 is fixedly sleeved on the outer wall of the groove 8 inside the limiting groove 10. Limiting plates 905 are provided on both sides inside the mounting groove 6. Through holes 906 are opened at the center of the adjacent end faces of the two limiting plates 905. The two through holes 906 are sleeved on the outside of the thermocouple temperature sensor 901. Limiting screws 907 are provided at the center of the front face of the two limiting plates 905 so that the contact point of the thermocouple temperature sensor 901 can be inserted into the groove 8 on the front face of the graphite plate 5, thereby realizing a direct contact temperature measurement method, which can achieve a direct and accurate temperature measurement effect, thus ensuring the accuracy of the sealing temperature.

[0031] A connecting rod 903 is fixedly connected to the center of the front end face of the thermocouple temperature sensor 901. A multi-stage conductive slip ring 904 is sleeved on the end of the connecting rod 903. The device is connected to the thermocouple temperature sensor 901 through the multi-stage conductive slip ring 904. The connection of the connecting wire and the connecting rod 903 will not be damaged due to the corner of the connection position, thus improving the service life of the device.

[0032] The fixed end of the multi-stage conductive slip ring 904 is fixedly connected to the connecting rod 903. The rotating end of the multi-stage conductive slip ring 904 is fixedly connected to the spring connecting wire 7. The connection through the spring connecting wire 7 will not affect the installation and disassembly, and the spring connecting wire 7 will not fall into the box 1 after installation.

[0033] An observation window 3 is fixedly connected to the center of the front face of the box door 4, which facilitates observation of the internal situation.

[0034] Two limiting screws 907 pass through the front end face of the two limiting plates 905 and extend to the rear end face of the two limiting plates 905 respectively. The ends of the two limiting screws 907 are threaded to the rear inner wall of the mounting groove 6, which facilitates installation.

[0035] The two limit screws 907, the limit block 902, and the limit plate 905 are all made of graphite. Graphite has excellent high-temperature stability and can maintain its physical and chemical properties unchanged in high-temperature environments. In high-temperature vacuum sealing equipment, the internal temperature of the equipment may reach thousands of degrees Celsius. Graphite can work normally at this high temperature without softening, deforming, or decomposing.

[0036] Working principle: During installation, first insert the thermocouple temperature sensor 901 into the groove 8, and the limiting block 902 into the limiting groove 10. Then, merge the two limiting plates 905 so that the two through holes 906 fit against the outside of the thermocouple temperature sensor 901. Then, use two limiting screws 907 to pass through the two limiting plates 905 and thread them onto the rear inner wall of the mounting groove 6 for easy installation.

[0037] The contact point of the thermocouple temperature sensor 901 can be inserted into the groove 8 on the front end of the graphite plate 5, thereby achieving a direct contact temperature measurement method. This can achieve a direct and accurate temperature measurement effect, thus ensuring the accuracy of the sealing temperature.

[0038] During disassembly, remove the two limit screws 907 and simultaneously remove the two limit plates 905. Then, pull out the thermocouple temperature sensor 901. During the removal and installation process, the connection via the spring connecting wire 7 will not affect the installation and disassembly. After installation, the spring connecting wire 7 will not be scattered inside the housing 1. After installation, the device and the thermocouple temperature sensor 901 are connected via the multi-stage conductive slip ring 904. This prevents damage to the spring connecting wire 7 due to the angle at the connection point between the spring connecting wire 7 and the connecting rod 903, thus improving the service life of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
