The heat-sensitive resistor carrying jig according to the embodiment includes a plurality of heat-sensitive resistor carrying areas for carrying square heat-sensitive resistor sheets 20, and the heat-sensitive resistor carrying areas include carrying portions corresponding to the shapes of the heat-sensitive resistor sheets 20 in orthographic projection. The carrying portions correspond to the square shapes of the heat-sensitive resistor sheets 20, and the square carrying portions are enclosed figures surrounded by a long side group and a wide side group. The long side group includes at least two long sides, and the wide side group includes at least two wide sides. The two ends of the long sides are connected to the two wide sides, respectively. Figure 3As shown, a first square groove 1 and a first square groove 5 are provided at the end of each long side, with a second square groove 3 provided between the first and second square grooves 3. The first and second square grooves 1 and 3 are connected by a supporting edge 2, and the second and first square grooves 3 and 5 are connected by a supporting edge 4. A third groove 7 and a third groove 9 are provided at the end of each wide side, with a supporting edge 8 provided between the third groove 7 and the third groove 9, and the third groove 7 and the third groove 9 are connected by the supporting edge 8. In this embodiment, the first square groove 1, the supporting edge 2, the second square groove 3, the supporting edge 4, the first square groove 5, the third groove 7, the supporting edge 8, and the third groove 9 are interconnected, collectively forming a thermistor bearing area. The first square groove 1, the second square groove 3, the first square groove 5, the third square groove 7, and the third square groove 9 are all connected to the support portion. The groove depths of the first square groove 1, the second square groove 3, the first square groove 5, the third square groove 7, and the third square groove 9 are the same as the depth of the support portion. The first square groove 1 is connected and integrated with the adjacent third square groove, and the first square groove 5 is connected and integrated with the adjacent third square groove 7. Moreover, the groove directions of the first square groove 1, the second square groove 3, the first square groove 5, the third square groove 7, and the third square groove 9 are all in the direction away from the support portion and the orthogonal projection area of the thermistor 20. In this embodiment, the first square groove 1, the second square groove 3, the first square groove 5, the third square groove 7, and the third square groove 9 are arranged. In addition to the orthogonal projection area of the thermistor 20 corresponding to the support portion, extended square grooves are provided at the four corners and the middle area of the long side, thereby expanding the area of the support portion in specific areas. The design of the support edges 2, 4, and 8 can be used to locate the position of the thermistor 20. The thermistor supporting fixture of this embodiment can effectively avoid the problem of thermistors having different sizes around and in the center of the supporting portion not being able to fit into the supporting portion. In addition, because the first square groove, the second square groove, and the third square groove on the edge of the supporting portion are provided for air release and provide operating space, loading and unloading the thermistor is also more convenient. The main dimensions of the supporting portion can be designed to be closer to the product specifications of the thermistor, thus avoiding the problem of large electrode eccentricity during thermistor printing.
[0021] Based on the specific dimensions of the thermistor sheet and the overall design of the thermistor support fixture, in this embodiment, the widths of the first square groove 1, the second square groove 3, the first square groove 5, the third square groove 7, and the third square groove 9 are 1 to 3 mm. The lengths of the first square groove 1, the second square groove 3, and the first square groove 5 are 10% to 40% of the length of the long side. The lengths of the third square groove 7 and the third square groove 9 are 15% to 40% of the length of the wide side. The lengths and widths of the first square groove 1, the second square groove 3, the first square groove 5, the third square groove 7, and the third square groove 9 can be adjusted vertically based on the specific dimensions of the thermistor sheet 20.
[0022] In actual application, if the length of the thermistor chip 20 is too long, multiple second square grooves can be arranged, and the multiple second square grooves are connected through the support edges. In actual application, if the width of the thermistor chip 20 is too long, a fourth square groove can be arranged between two third square grooves, the fourth square groove can be arranged with one or multiple, and the third square groove and the fourth square groove are connected through the support edges.
[0023] As shown in Figure 3 The first square groove 1, the support edge 2, the second square groove 3, the support edge 4, the first square groove 5, the third square groove 7, the support edge 8, and the position where the third square groove 9 is connected are all provided with a round corner: the position where the first square groove 1 and the support edge 2 are connected is provided with a round corner 11; the position where the second square groove 3 and the support edge 4 are connected is provided with a round corner 10; and the position where the first square groove 5 and the third square groove 7 are connected is provided with a round corner 6. On the one hand, the design of the round corner can effectively avoid dust accumulation and make it more convenient to clean the dust. On the other hand, the design of the round corner can avoid hand scratches caused by sharp connection positions during the processing of the thermistor chip 20, and can also avoid scratches of the thermistor chip 20 caused by the collision of the thermistor chip 20 and the corners, which can cause appearance or performance defects. In actual application, the radius of the round corner is set to 0.5 to 2.5 mm, which can be flexibly adjusted as needed.
[0024] Therefore, compared with the prior art, the thermistor carrying jig of the present embodiment is more convenient to load and unload, and the size of the carrying part for placing the thermistor chip can be designed to be closer to the specifications of the product. In addition, the thermistor carrying jig of the present embodiment can effectively reduce the eccentricity of the electrode when printing the electrode of the thermistor chip on the ceramic chip.
[0025] In order to prove that the thermistor carrying jig of the present embodiment can significantly reduce the performance and appearance defects of the thermistor chip during the processing of the thermistor, effectively avoid the placement of the thermistor chip into the carrying part, and has the advantages of the prior art thermistor carrying jig, the thermistor carrying jig of the present embodiment and the prior art thermistor carrying jig are used to process thermistor chips with a ceramic chip specification length of 24±0.2mm and a width of 15±0.2mm, and the printing screen size is 22±0.1mm in length and 13±0.1mm in width. Each batch has 1000 pieces, and the results of electrode eccentricity, appearance defects, and placement into the carrying jig are shown in Table 1. The thermistor carrying jig of the present embodiment can reduce the defects by about 3%, and the corners are visually free of dust after multiple uses.
[0026] Table 1 The heat-sensitive resistance bearing jig of the present application is provided with open square grooves, namely first square groove, second square groove and third square groove, around the four edges and in the middle of the heat-sensitive resistance bearing part corresponding to the heat-sensitive resistance bearing area, and the first square groove, the second square groove and the third square groove are all arranged in the direction away from the heat-sensitive resistance sheet in the bearing part orthographic projection area, so as to expand the area of the bearing part in a specific area, which can effectively avoid the problem that the heat-sensitive resistance sheet with size difference around and in the middle of the bearing part cannot be put into the bearing part, and because the first square groove, the second square groove and the third square groove around the edge of the bearing part can vent and provide operation space, the feeding and discharging of the heat-sensitive resistance sheet is also more convenient, the main size design of the bearing part can be closer to the product specification of the heat-sensitive resistance, and the problem of large electrode eccentricity during printing of the heat-sensitive resistance can be avoided.
