Abstract
Description
Technical Field
[0001] This application relates to the field of temperature measurement technology, and more specifically, to a hot plate temperature measuring device. Background Technology
[0002] The hot plate inside the photoresist coating and developing equipment is a key module in semiconductor manufacturing. It is mainly used for substrate heating in the photolithography process. Through precise temperature control, it enables processes such as drying after photoresist coating and hardening after exposure. Its uniformity and stability directly affect the pattern transfer quality of the photoresist.
[0003] During use, the hot plate may experience a deviation between the set temperature and the actual temperature. Since the coating and developing equipment cannot calculate and measure this error, an external temperature measuring tool is needed to calculate and measure it to correct the error. Existing temperature measuring tools fix the temperature probe and the handheld lever together, and the temperature is measured by gripping the lever. When measuring by hand, the shaking during the grip can easily cause the temperature probe to lose contact with the hot plate, resulting in inaccurate temperature readings. Utility Model Content

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0032] Existing hot plate temperature measuring tools work by fixing a temperature probe to a handheld handle. The operator grips the handle to bring the probe's measuring surface into contact with the surface of the hot plate to be measured. However, due to the operator's field of vision and fatigue from prolonged operation, the probe is prone to shaking during the measurement process, making it difficult to maintain constant contact with the hot plate and resulting in inaccurate temperature readings.
[0033] Based on the above technical issues, such as Figures 1 to 3 As shown, one aspect of this application provides a hot plate temperature measuring device 100, including a base 110, a measuring plate 120, and a temperature probe 130. The base 110 is placed inside a machine tool 200 and located above a hot plate 210 inside the machine tool 200. A fixing hole 1101 is provided on the base 110. The measuring plate 120 is installed in the fixing hole 1101. A temperature measuring hole 121 is provided on the measuring plate 120. The temperature probe 130 is installed on the measuring plate 120 and passes through the temperature measuring hole 121 to contact the hot plate 210. The temperature probe 130 is used to measure the temperature of the hot plate 210.
[0034] Specifically, the hot plate temperature measuring device 100 includes a base 110, a measuring plate 120, and a temperature probe 130. The base 110 is located inside the machine base 200 and positioned above the hot plate 210. It should be noted that... Figure 1 The middle section represents part of the structure of the machine tool 200. A certain gap exists between the base 110 and the hot plate 210, allowing only the temperature probe 130 to contact the hot plate 210 during temperature measurement. A fixing hole 1101 is provided on the base 110, and the measuring plate 120 is installed within the fixing hole 1101. For example, the measuring plate 120 and the fixing hole 1101 can be press-fitted together or overlapped and limited by a subsequent step 1102. A temperature measuring hole 121 is provided on the measuring plate 120 for mounting the temperature probe 130. The temperature probe 130 passes through the temperature measuring hole 121 and through the measuring plate 120, allowing it to contact the surface of the hot plate 210 below the base 110 to measure the temperature of the surface being measured. It should be noted that the measuring plate 120 is made of a high-temperature resistant material and will not be damaged by the heat of the hot plate 210. The temperature probe 130 is installed through the temperature measuring hole 121 on the measuring plate 120. During the temperature measurement process, the temperature probe 130 is supported by the base 110 and the measuring plate 120 placed inside the machine 200. It does not require hand-holding and makes it easy for the temperature probe 130 to keep in contact with the surface of the hot plate 210 to be measured, thereby improving the accuracy of the temperature measurement results.
[0035] This application involves mounting a temperature probe 130 onto a measuring plate 120, which is then installed within a fixing hole 1101 on a base 110. The base 110 is positioned above the hot plate 210. The temperature probe 130 passes through a temperature measuring hole 121 on the measuring plate 120 and contacts the hot plate 210 to measure its temperature. Furthermore, the temperature probe 130 can be connected to a processor via wired or wireless connection. The processor converts the temperature signal measured by the probe 130 into a digital signal and displays the temperature value on a screen, providing a clear visual representation of the temperature of the surface of the hot plate 210 to be measured. The processor can be an internal processor of the machine 200 or an external processor.
[0036] In some embodiments, the measuring plate 120 and the fixing hole 1101 can be connected by screws, rivets, hinges, or other means, and the specific connection is not limited.
[0037] In some embodiments, multiple temperature measuring holes 121 may be provided on the measuring plate 120. The number, area, and specific arrangement of the temperature measuring holes 121 can be set according to specific circumstances and are not limited here. The number of temperature measuring probes 130 may be one or more, and their number may be equal to or less than the number of temperature measuring holes 121. For example, when monitoring the temperature of the hot plate 210, only one temperature measuring probe 130 may be set to perform single-point measurement of the hot plate 210 through one temperature measuring hole 121, or two or more temperature measuring probes 130 may be set, with each temperature measuring probe 130 contacting the hot plate 210 through its corresponding temperature measuring hole 121, thereby performing multi-point measurement.
[0038] Optionally, such as Figures 1 to 3 As shown, the base 110 includes a movable part 111 and a fixed part 112. The fixed part 112 is fixedly disposed on the machine base 200, and the movable part 111 is slidably disposed on the fixed part 112 so as to move closer to or away from the hot plate 210.
[0039] Specifically, the fixed part 112 is located on one side of the opening of the machine base 200 and is fixedly connected to the machine base 200. The movable part 111 is slidably connected to the fixed part 112 on the side away from the opening of the machine base 200. The fixed hole 1101 is provided on the movable part 111. The movable part 111 is located directly above the hot plate 210. The movable part 111 can move closer to or away from the hot plate 210 by sliding on the fixed part 112.
[0040] When temperature measurement is required, the measuring plate 120 is placed in the fixing hole 1101 of the moving part 111, and the temperature probe 130 is placed in the temperature measuring hole 121 of the measuring plate 120. The base 110 is placed inside the machine tool 200. The fixing part 112 is fixedly set on the machine tool 200. At this time, the moving part 111 is away from the hot plate 210. By controlling the moving part 111 to slide relative to the fixing part 112, the measuring plate 120 and the temperature probe 130 on the moving part 111 gradually approach the hot plate 210 until the temperature probe 130 is in contact with the surface of the hot plate 210 to be measured. In this way, the temperature of the hot plate 210 can be measured. Since the entire hot plate temperature measuring device 100 is supported by the fixing part 112 and the machine tool 200 during the entire temperature measurement process, there is no need to hold it. Therefore, it can be ensured that the temperature probe 130 and the surface of the hot plate 210 to be measured are always in contact. When temperature measurement is not required, the moving part 111 slides in the opposite direction to the fixed part 112, causing the measuring plate 120 and temperature probe 130 on the moving part 111 to gradually move away from the hot plate 210. Then, the base 110 and the measuring plate 120 and temperature probe 130 located on the base 110 are removed from the machine 200 to complete the temperature measurement. By sliding the moving part 111 relative to the fixed part 112, the moving part 111 has the function of moving closer to or away from the hot plate 210. This setting ensures that during the entire process of installing the hot plate temperature measuring device 100 into the machine 200, the moving part 111 in the hot plate temperature measuring device 100 is always away from the hot plate 210, reducing the risk of unintended contact with the hot plate 210 during the installation of the fixed part 112. Only after the fixed part 112 is fixed is the moving part 111 controlled to slide to achieve contact between the temperature probe 130 and the surface of the hot plate 210 to be measured.
[0041] In some embodiments, the connection between the fixing part 112 and the machine base 200 can be a snap-fit connection 114, a threaded connection, or a plug-in connection, etc., and is not limited here. For example Figure 2 As shown, a buckle 114 is fixedly provided on the side of the fixed part 112 away from the moving part 111. A slot that cooperates with the buckle 114 is provided on the machine base 200. When the base 110 is installed into the machine base 200, the base 110 and the machine base 200 can be fixed by inserting the buckle 114 into the slot.
[0042] Optionally, such as Figure 1 and Figure 4 As shown, the base 110 also includes a drive assembly 113, which is disposed on the fixed part 112 and drivenly connected to the moving part 111.
[0043] Specifically, the moving part 111 is moved relative to the fixed part 112 by the drive assembly 113. When temperature measurement is required, the drive assembly 113 drives the moving part 111 to move closer to the hot plate 210; when the temperature measurement is completed, the drive assembly drives the moving part 111 to move away from the hot plate 210.
[0044] In some implementations, the drive component 113 can be an automatic component or a manual component. For example, when the drive component 113 is an automatic component, it can be a linear motor, a hydraulic cylinder, or a pneumatic cylinder, and there is no specific limitation.
[0045] Optionally, such as Figure 1 and Figure 4 As shown, the drive assembly 113 includes an active member 1131 and a driven member 1132. The active member 1131 is slidably disposed on the fixed part 112. The active member 1131 is drivenly connected to the driven member 1132 via the connecting member 1133. The driven member 1132 is fixed to the moving part 111.
[0046] Specifically, the driving member 1131 slides on the fixed part 112. For example, a first slide rail is provided on the fixed part 112, and the driving member 1131 is slidably mounted on the first slide rail to achieve movement of the driving member 1131 relative to the fixed part 112. As the driving member 1131 moves, the moving part 111, which is fixedly connected to the driven member 1132, also slides relative to the fixed part 112 through the connecting member 1133, so that the moving part 111 moves closer to or away from the hot plate 210. It should be understood that the extension direction of the first slide rail is the sliding direction of the driving member 1131. Therefore, it can be reasonably set according to actual needs, for example... Figure 1 In the middle, the first slide rail can extend in the direction indicated by arrow A.
[0047] Optionally, such as Figure 1 and Figure 4 As shown, the drive assembly 113 also includes a guide wheel 1134 rotatably disposed on the fixed part 112, the connecting member 1133 is a flexible member, the sliding direction of the active member 1131 is parallel to the plate surface of the measuring plate 120, the sliding direction of the moving part 111 intersects with the sliding direction of the active member 1131, and the flexible member and the guide wheel 1134 are in contact and cooperate.
[0048] Specifically, the driving member 1131 and the driven member 1132 are connected by a connecting member 1133, which is a flexible member. By utilizing the cooperation between the guide wheel 1134 and the flexible member, it is possible to accommodate the driving member 1131 and the driven member 1132 moving in different directions, for example... Figure 4The driving member 1131 moves in the direction indicated by arrow A, and the driven member 1132 moves in the direction indicated by arrow B. Driving the driving member 1131 causes the connecting member 1133 to drive the driven member 1132 to move. The sliding direction of the driving member 1131 is parallel to the surface of the measuring plate 120, and the sliding direction of the moving part 111 is towards or away from the hot plate 210. The sliding direction of the moving part 111 intersects with the sliding direction of the driving member 1131, for example, perpendicular to the surface of the measuring plate 120.
[0049] For example, the active component 1131 along such Figure 1 and Figure 4 Moving in the direction indicated by arrow A, the driving component 1131 drives the connecting component 1133 to move, and the transmission direction is changed through the guide wheel 1134, so that the connecting component 1133 drives the driven component 1132 along... Figure 4 The moving part 111 moves away from the hot plate 210 in the direction indicated by arrow B; the driving member 1131 moves along the direction indicated by arrow B. Figure 4 The movement in the direction indicated by arrow C changes the transmission direction via guide wheel 1134, causing connecting member 1133 to drive driven member 1132 along... Figure 4 The moving part 111 moves in the direction indicated by the arrow D, that is, the moving part 111 moves closer to the hot plate 210. This design reduces the space occupied by the drive assembly 113, and also facilitates the movement of the moving part 111 by driving the driven member 1132.
[0050] In some embodiments, the connector 1133 can be a track, belt, or rope, and there is no specific limitation.
[0051] Optionally, such as Figure 1 and Figure 4 As shown, the fixing part 112 includes an inner cavity 1121, and a strip hole 1122 communicating with the inner cavity 1121 is provided on the side of the fixing part 112 away from the hot plate 210. The driving assembly 113 is located in the inner cavity 1121, and the active member 1131 has a toggle part 1135, which extends to the outside of the fixing part 112 through the strip hole 1122.
[0052] Specifically, the drive assembly 113 is disposed within the inner cavity 1121 of the fixing part 112, thus protecting the drive assembly 113 from interference by external components during its operation. A strip-shaped hole 1122 is provided on the fixing part 112, located on the side opposite to the hot plate 210 and communicating with the inner cavity 1121. The actuating part 1135 on the driving member 1131 protrudes outward from the fixing part 112 through the strip-shaped hole 1122. On one hand, when driving the driving member 1131, only the actuating part 1135 protruding outward from the fixing part 112 needs to be driven, avoiding the cumbersome process of extending into the strip-shaped hole 1122 to drive the driving member 1131, thus facilitating the driving of the driving member 1131. On the other hand, the strip-shaped hole 1122 allows the driving member 1131 to move along the extension direction of the strip-shaped hole 1122, enabling the driving member 1131 to move along... Figure 4 Moving in the direction indicated by arrow A or arrow C facilitates the movement of the moving part 111 relative to the hot plate 210, allowing it to move closer to or further away from the hot plate.
[0053] Optionally, such as Figure 1 and Figure 6 As shown, a latch 1123 is provided on the fixed part 112. After the driving member 1131 drives the moving part 111 away from the hot plate 210 via the driven member 1132, the driving member 1131 and the latch 1123 engage and lock together.
[0054] Specifically, when the moving part 111 needs to move away from the hot plate 210, the driving member 1131 drives the driven member 1132, which is fixedly connected to the moving part 111, to move. The driving member 1131 is engaged and fixed with the latch 1123 provided on the fixed part 112. At this time, the moving part 111 moves to the furthest point away from the hot plate 210 and can remain in this position without external force. Conversely, when it needs to move closer to the hot plate 210, the driving member 1131 is grasped, driving the driving member 1131 to disengage from the latch 1123. With the help of its own weight, the moving part 111 tends to move closer to the hot plate 210. As the driving member 1131 gradually moves, the moving part 111 can move closer to the hot plate 210 by its own weight. When the active member 1131 and / or the moving part 111 are blocked after moving to the limit position, the moving part 111 moves to the closest point to the hot plate 210, and the temperature probe 130 is in contact with the surface of the hot plate 210 to be measured, for measuring the temperature of the hot plate 210.
[0055] In some embodiments, two drive components 113 may be provided. The arrangement of the strip hole 1122, the latch 1123, and the first slide rail corresponds to the number of drive components 113. The two drive components 113 jointly drive the moving part 111 to move closer to or away from the hot plate 210. It should be noted that the directions of the two driving members 1131 when driving the moving part 111 to move closer to or away from the hot plate 210 can be the same or opposite.
[0056] In some embodiments, a second slide rail is fixedly mounted on the fixed part 112, and a slider is fixedly mounted on the moving part 111. The slider is slidably mounted on the second slide rail, thereby achieving a sliding arrangement between the moving part 111 and the fixed part 112. The extension direction of the second slide rail is perpendicular to the surface of the hot plate 210.
[0057] In some embodiments, a guide rod is fixedly mounted on the fixed part 112, and a bushing is fixedly mounted on the moving part 111. The bushing is slidably sleeved on the outer periphery of the guide rod, thereby realizing the sliding arrangement of the moving part 111 and the fixed part 112. The guide rod can be arranged in a direction perpendicular to the surface of the hot plate 210.
[0058] Optionally, such as Figure 2 and Figure 3 As shown, the temperature probe 130 includes a temperature measuring head 131 and a limiting part 132 connected at an angle; the limiting part 132 contacts the plate surface of the measuring plate 120, and the temperature measuring head 131 passes through the measuring plate 120 through the temperature measuring hole 121 and contacts the hot plate 210.
[0059] Specifically, the temperature probe 130 includes a temperature measuring head 131 and a limiting part 132. The temperature measuring head 131 and the limiting part 132 are fixedly connected at an angle, which should be noted as 90° or approximately 90°. The limiting part 132 overlaps with the upper surface of the measuring plate 120. This overlap between the measuring plate 120 and the limiting part 132 provides support for the entire temperature probe 130, and the temperature measuring head 131 contacts the hot plate 210. The limiting part 132 facilitates the movement of the moving part 111 as it approaches or moves away from the hot plate 210, thereby driving the temperature measuring head 131 fixedly connected to the limiting part 132.
[0060] Optionally, such as Figure 5 As shown, the temperature probe 130 includes a temperature measuring head 131 and a limiting part 132 connected at an angle; the temperature measuring hole 121 includes a first sub-hole 1211 and a second sub-hole 1212 connected to each other, a limiting platform 1213 is provided at the connection between the first sub-hole 1211 and the second sub-hole 1212, the limiting part 132 is located in the first sub-hole 1211 and abuts against the limiting platform 1213, the temperature measuring head 131 passes through the second sub-hole 1212 to pass through the measuring plate 120 and contacts the hot plate 210.
[0061] Specifically, the temperature measuring hole 121 includes a first sub-hole 1211 and a second sub-hole 1212, which are connected at an angle. It should be noted that this angle is used to accommodate the temperature measuring head 131 and the limiting part 132, which are connected at an angle. A limiting platform 1213 is provided at the connection between the first sub-hole 1211 and the second sub-hole 1212. When the temperature measuring probe 130 is placed inside the temperature measuring hole 121, the limiting part 132 abuts against the limiting platform 1213, and the temperature measuring head 131 contacts the hot plate 210. This arrangement, by setting the first sub-hole 1211 to partially or completely accommodate the limiting part 132, avoids the limiting part 132 being too high and causing it to collide with the top wall of the machine 200 during movement.
[0062] Optionally, such as Figure 1 As shown, the inner wall of the fixing hole 1101 is provided with a step 1102, which overlaps with the measuring plate 120. A guide surface 1103 is provided between the step 1102 and the inner wall of the fixing hole 1101. The guide surface 1103 is used to guide the measuring plate 120 to overlap with the step 1102.
[0063] Specifically, step 1102 is fixedly arranged around the inner wall of fixing hole 1101, and measuring plate 120 is placed on step 1102. A guide surface 1103 is provided around the outer periphery of step 1102, so that measuring plate 120 can slide into step 1102 located on the inner wall of fixing hole 1101 through guide surface 1103.
[0064] In some embodiments, a notch is provided around the periphery of the upper surface of the step 1102 to facilitate the removal of the measuring plate 120 from the step 1102. The number of notches is set according to the specific situation and is not limited.
[0065] In some embodiments, a protrusion is fixedly provided on the upper surface of the step 1102, and a limiting port is provided on the measuring plate 120. When the measuring plate 120 is placed on the step 1102, the protrusion and the limiting port cooperate to limit the step 1102 and the measuring plate 120, thereby preventing the measuring plate 120 from moving during the temperature measurement process and improving the accuracy of the temperature measurement.
[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
