[0002] Temperature is an extremely important variable that needs to be controlled during the manufacturing process of liquid crystal substrate glass. Therefore, the production line must monitor the temperature in real time. Currently, the temperature detection instruments installed and used on the production line include PT100 thermal resistors, bimetal indicating thermal resistors, and thermocouples of various models. For areas with high temperature detection requirements, thermocouples are mostly used for detection. When installing the thermocouple in the forming area, there are strict requirements for the insertion depth of the thermocouple. Since the furnace is enclosed and the insertion depth of the thermocouple cannot be measured, before insertion, the insertion depth dimension must be marked on the thermocouple first, so that another person can see the insertion distance of the thermocouple from the far and near ends of the furnace inward, and the insertion depth of the thermocouple can be determined by means of the red mark.

[0003] There are a large number of thermocouples in the forming area, and there is no special marking tool. It is necessary to borrow a steel ruler and assist with two people for size marking. One person stabilizes the thermocouple and the steel ruler, and the other person draws a circle for marking. Due to manual operation errors, the marked size may lack accuracy; at the same time, during the manual marking process, in order to ensure the accuracy of the line drawing, the line drawing marking speed is slow and the operation efficiency is low. Therefore, in summary, in the current thermocouple size marking, due to the involvement of a large amount of manual operation, the accuracy of the size marking is insufficient, and the overall operation efficiency needs to be further improved.

[0025] How to provide a special tool for thermocouple size marking to improve the accuracy and efficiency of thermocouple size marking.

[0026] As Figure 1 and Figure 2 shown, the present invention provides a special tool for thermocouple size marking, including a tool body and a marking component disposed thereon.

The tool body is formed with a sliding area corresponding to the sliding part along the scale direction of the scale 2, and the sliding part can slide along the sliding area and be positioned; The marking end of the marking component can contact or disengage from the area to be marked of the thermocouple to be marked through adjustment, so as to mark or take out the thermocouple to be marked.

[0027] The special tool for thermocouple size marking of the present invention divides the tool into a thermocouple installation part and a marking part. The thermocouple installation part ensures the accurate positioning and vertical alignment of the thermocouple. The marking part realizes fast and stable circular marking operation through sliding adjustment and contact marking. The overall structure of the special tool of the present invention simplifies the manual operation process, avoids the errors of multi-person cooperation, and improves the accuracy and efficiency of thermocouple size marking.

[0028] In some embodiments, a damping piece is designed inside the slider 1 of the present invention. As an option, it can be but is not limited to a copper damping piece. The copper damping piece can contact the tool body to prevent the slider 1 from sliding. Through the structure of the left and right pressing pieces 5 and the long groove 10 and in combination with the first locking nut 6, the stable sliding and accurate positioning of the slider 1 are realized, and the error caused by the offset of the slider 1 during the marking process is avoided. As an option, the slider 1 of the present invention is of a groove structure and is matched with the first locking nut 6 through a screw hole, which increases the contact area between the slider 1 and the tool body and improves the stability during locking.

[0029] As a preference, the present invention designs a marker pen holder 7 and a second locking nut 8, so that the marker pen 9 can be installed and disassembled conveniently. At the same time, the nib of the marker pen 9 is fixed by radial pressure, avoiding shaking or offset during marking, and ensuring uniform pressure of the locking nut on the marker pen.

[0030] Furthermore, in the present invention, the concave structure of the placement table 4 is aligned with the zero scale of the scale 2, so that the detection end of the thermocouple 11 is directly matched with the scale reference after being placed. The concave surface is arc-shaped and adapted to the outer surface of the thermocouple 11, increasing the contact area of the detection end of the thermocouple 11 and preventing sliding or tilting. The inner diameter of the fixing tube 3 is adapted to the outer diameter of the thermocouple 11, ensuring that there is no radial offset when the thermocouple 11 vertically passes through, and improving the error caused by the tilt of the thermocouple.

[0031] The present invention also provides a working method of a special tool for thermocouple size marking, including the following steps: S1. Pass the thermocouple to be marked through the fixed tube 3 and place the detection end of the thermocouple to be marked on the placement table 4; S2. Slide the marking assembly along the direction of the scale 2 to the preset scale position of the thermocouple to be marked and position the marking assembly; S3. Adjust the marking assembly so that the marking end of the marking assembly contacts the area to be marked on the thermocouple to be marked, and the marking end of the marking assembly applies a mark along the radial direction of the thermocouple to be marked; S4. Adjust the marking assembly so that the marking end of the marking assembly disengages from the area to be marked on the thermocouple to be marked, take out the thermocouple to be marked, and complete the size marking of the thermocouple to be marked.

[0032] The whole of the special tool of the present invention is made of stainless steel, enhancing the high-temperature resistance and corrosion resistance of the tool. Combined with the above working method, it can be applied to industrial environments such as the manufacture of liquid crystal glass substrates and has a better service life.

Pass the thermocouple 11 through the fixed tube 3, place the detection end of the thermocouple 11 on the placement table 4, then move the slider 1 up and down to make the marker pen 9 reach the position where the thermocouple 11 needs to be marked, fix the slider 1, and rotate the thermocouple 11. The marker pen 9 will draw a circle of marks at the corresponding position of the thermocouple 11 to meet the relevant operation requirements. In actual working conditions, when installing the thermocouple 11 on site, a large number of thermocouples 11 need to be size-marked. The special tool provided by the present invention greatly improves the marking efficiency and accuracy, reduces the operation time, and improves the installation operation efficiency of the thermocouple.

[0035] In the present invention, the marking position is determined according to the scale 2, ensuring the accuracy of the marking. The overall height of the special tool is 20 cm, and the whole special tool is made of stainless steel. The slider 1 is located on the left side of the scale 2 and is fixed on the tool body by means of left and right pressing pieces 5 for sliding. The inside of the slider 1 is equipped with a copper damping piece. When the first locking nut 6 is tightened, the copper damping piece will prevent the slider 1 from sliding.

[0036] Screw holes are provided on the left and right pressing plates 5 and fixed to the slider 1 through screws. A marker pen holder 7 for installing a marker pen 9 is connected to the slider 1, and the marker pen 9 is fixed by a second locking nut 8. The zero scale of the scale 2 is located at the bottom, and the maximum scale is five centimeters. The scale 2 is located directly behind the placement table 4. The size of the fixing tube 3 is just large enough to pass through the thermocouple 11, and the center of the tube of the fixing tube 3 is aligned with the center of the concave surface of the placement table 4. The placement table 4 is of a rectangular structure, and there is a concave surface in the middle of the rectangular structure for placing the detection end of the thermocouple 11. The bottom of the concave surface is flush with the zero scale of the scale 2.

[0037] During the operation, the slider 1 and the left and right clamping plates 5 of the present invention are fixed to the tool body by the first locking nut 6, and the slider 1 can be fixed by rotating the first locking nut 6. The marker pen 9 is passed through the marker pen holder 7 and then fixed by the second locking nut 8. The slider 1 is slid up and down to move the marker pen 9 up and down. After moving to the position where the thermocouple 11 needs to be marked, the slider 1 is fixed.

[0038] The thermocouple 11 is passed through the fixing tube 3, and the detection end of the thermocouple 11 abuts against the placement table 4. The position of the marker pen 9 is adjusted to a suitable position with the help of the scale 2. The thermocouple 11 or the tool body is rotated to draw a line on the thermocouple 11 with the marker pen 9 to complete the marking. By means of the special tool for thermocouple size marking of the present invention, efficient and accurate thermocouple marking work can be realized, which has certain practical significance.
