Description

Technical Field

[0001] The utility model relates to the technical field of transmitter processing, in particular to a production tool for a single crystal silicon transmitter. Background Art

[0002] At present, in the production process of single crystal silicon core, the process of determining the amount of silicone oil inside the product is relatively simple. Since the silicone oil is added under vacuum, the amount of oil added cannot be controlled. The only way is to fill the core inner line with oil, and then squeeze the diaphragms on both sides of the core through air pressure or other means to expel the excess silicone oil into the oil-fixing pipe. Then, the pressure on both sides of the core is stopped, and the oil level in the oil-fixing pipe drops back. The oil fixing of the core is achieved by manually controlling the amount of silicone oil falling back.

[0003] However, with regard to the existing technology, in actual operation, the extrusion method to control the amount of oil inside the core requires the cooperation of at least two workers, that is, one person fixes the seal of the transmitter and applies air pressure, and the other person needs to hold the fixed oil pipe to keep it vertical and control the amount of silicone oil falling back in the fixed oil pipe. In this way, the control of the fixed oil amount inside the core depends entirely on the cooperation between the workers, and the production efficiency is low. If the two people do not cooperate well, there will be product quality risks.

[0011] Preferably, the second fixture is further equipped with a rotation drive source and a gear mounted on the output shaft of the rotation drive source, the gear is meshed with the tooth groove on the sealing block, and the rotation of the driving gear drives the sealing block to move along the slide groove.

[0012] Preferably, the second tooling is further provided with an avoidance area, and the first tooling and the core mounted on the first tooling are at least partially located in the avoidance area.

[0013] Preferably, the first tooling includes a base plate, a support portion and two clamping blocks, the support portion is fixedly mounted on the base plate, the support portion is provided with a support surface that fits the core body, and a positioning pin is arranged on the support surface, the positioning pin is plugged into the positioning hole on the core body, the support portion is located between the two clamping blocks, one of the clamping blocks is fixedly mounted on the base plate, and the other clamping block is slidably mounted on the base plate through a linear slide rail to adjust the distance between the two clamping blocks.

[0015] At least one of the above technical solutions adopted in this practical embodiment can achieve the following beneficial effects:

[0016] First, by providing two vertically extending mounting slots on the second fixture, the two oil pipes are inserted into the two mounting slots to secure them vertically. This eliminates the need for a separate worker to hold the oil pipes upright during the subsequent oiling process, allowing the entire process to be completed by one person. This eliminates the need for two people to coordinate and affect oiling accuracy, while also improving production efficiency.

[0017] Secondly, automatic oil control avoids operational errors in manual oil setting (mainly due to the error of delayed response when observing the oil amount by eye, and when the actual amount of oil set deviates greatly from the required amount, it will lead to product accuracy deviation, and in severe cases, the product will be scrapped), thereby improving efficiency and ensuring the processing consistency of core products.

DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of this utility more clear, the following will be combined with the specific embodiments of this utility and the corresponding drawings to clearly and completely describe the technical solutions of this utility. Obviously, the embodiments described are only part of the embodiments of this utility, not all of them. Based on the embodiments of this utility, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility.

[0030] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1 to 8 As shown, this practical embodiment provides a production tool for a single crystal silicon transmitter, which is used for the core 2 of the single crystal silicon transmitter and mainly includes a first tool 1, a fixed oil pipe 3 and a second tool 4.

[0032] The first tooling 1 is used to fix the core 2 and keep the oil drain port 21 of the core 2 (in some practical applications, the core 2 has two oil drain ports 21 ) open vertically upward, and to discharge the silicone oil inside the core 2 by pressurizing the core 2 .

[0033] In some practical applications, such as Figure 1 and Figure 5 As shown, the first tooling 1 includes a base plate 11, a support portion 12 and two clamping blocks 13. The base plate 11 serves as the basic part of the entire tooling and is used to support the structure and operation of the entire tooling. The support portion 12 is fixedly mounted on the base plate 11 and is located between the two clamping blocks 13, and is used to carry the core 2; specifically, the support portion 12 is provided with a support surface 121 that fits the core 2, and a positioning pin 122 provided on the support surface 121, the support surface 121 is used to fit the outer contour of the core 2 to ensure that the core 2 is stably placed in the tooling, and the positioning pin 122 is provided on the support surface 121, and is used to plug and cooperate with the positioning hole 23 on the core 2 to ensure the correct position of the core 2 and ensure that its oil discharge port 21 is set vertically upward. One of the clamping blocks 13 is fixedly mounted on the base plate 11, and the other clamping block 13 is slidably mounted on the base plate 11 through a linear slide rail to adjust the distance between the two clamping blocks 13.

[0034] In some practical applications, such as Figure 1 、 Figures 5 to 8 As shown, the first tooling 1 is also formed with a pressurized channel, one end of which is used to communicate with an external air source, and the other end is directly opposite the core 2, so as to pressurize the core 2 and discharge the silicone oil inside the core 2. Specifically, the clamping block 13 is provided with an air inlet pipe 14 and an air inlet channel 132 connected to the air inlet pipe. When the core 2 is clamped by the clamping block 13, the clamping block 13 and the core 2 are in sealed contact, forming a chamber 131 connected to the air inlet channel 132, so that the core diaphragm 22 is pressurized through the air inlet pipe 14 to discharge the silicone oil inside the core 2. The air inlet pipe 14 and the air inlet channel 132 connected to the air inlet pipe constitute the aforementioned pressurized channel.

[0035] During actual operation, the staff places the core body 2 on the supporting surface 121 of the supporting part 12, and inserts the positioning pin 122 into the positioning hole 23 on the core body 2 to ensure that the position of the core body 2 is correct. At this time, one of the clamping blocks 13 abuts against the left end face of the core body 2, and the position of the other clamping block 13 is adjusted by the linear slide rail so that the two clamping blocks 13 respectively abut against the left and right ends of the core body 2.

[0036] When the two clamping blocks 13 are respectively against the left and right ends of the core 2, the clamping blocks 13 are in sealed contact with the core 2 to form a chamber 131 connected to the air inlet channel 132, and the diaphragms 22 at the left and right ends of the core 2 are respectively located in the two chambers 131. In this way, the diaphragms 22 on both sides of the core 2 can be squeezed by passing gas into the two air inlet pipes 14. After the diaphragms 22 are squeezed, the silicone oil is discharged from the oil drain port 21 under the action of the squeezing force; in other practical applications, an elastic gasket is added to the inner end chamber 131 of the clamping block 13. The elastic gasket can better adapt to the curved surface shape of the core 2 when the clamping block 13 is against the two ends of the core 2, thereby improving the sealing effect.

[0037] Two fixed oil pipes 3 are provided and are connected to the two oil discharge ports 21 respectively, for collecting or temporarily storing the silicone oil discharged from the oil discharge ports 21 .

[0038] The second fixture 4 is positioned adjacent to the first fixture 1 and is provided with two vertically extending mounting slots 41. The two oil pipes 3 are inserted into the respective mounting slots 41 to secure them in a vertical position. This eliminates the need for a separate worker to hold the oil pipes 3 upright during the subsequent oiling process. The entire process can be completed by a single person, eliminating the need for two personnel to coordinate and affect oiling accuracy, while also improving production efficiency.

[0039] In some practical applications, such as Figures 1 to 3 As shown, the fixed oil pipe 3 and the oil discharge port 21 connected thereto are coaxially arranged. Both mounting grooves 41 are configured as long rectangular grooves. The fixed oil pipe 3 is inserted into the corresponding mounting groove 41 by means of interference fit to achieve fixation of the fixed oil pipe 3. This method also facilitates the removal and installation of the fixed oil pipe 3 by the staff. Each fixed oil pipe 3 is connected to the corresponding oil discharge port 21 by a hose 31. The design of the hose 31 is mainly to facilitate the positioning of the core 2. That is, the core 2 can be fixed by the first tooling 1 first, and then the flexible characteristics of the hose 31 can be used to install the fixed oil pipe 3 in the corresponding mounting groove 41, avoiding the inconvenience caused to the staff by fixing the fixed oil pipe 3 and the core 2 at the same time.

[0040] In some practical applications, the oil setting link of the core 2 can be assisted by at least the following structures or methods:

[0041] First, the oil-fixing pipe 3 is sealed manually, and the specific operation is as follows: the core body 2 is fixed by the first tooling 1, the oil-fixing pipe 3 is fixed in the mounting groove 41, and air is added through the air inlet pipe 14. The diaphragm 22 of the core body 2 is pressurized to discharge the silicone oil inside the core body 2. When the excess silicone oil in the core body 2 is discharged into the oil-fixing pipe 3, that is, the silicone oil is no longer discharged, a sealing paper is pasted on the top open end of each oil-fixing pipe 3 to achieve sealing, and then the air addition is stopped. Subsequently, the steel ruler is aligned with the upper end of the oil-fixing pipe 3, the sealing paper is removed, and the silicone oil in the oil-fixing pipe 3 falls back. After reaching the set required scale line, the oil-fixing pipe 3 is pulled out, thereby completing the oil fixing operation.

[0042] Secondly, compared with the above manual method, this method requires the addition of mechanical structure to realize automatic oil setting, such as Figures 1 to 3 As shown, it is first necessary to ensure that the top openings of the two fixed oil pipes 3 are flush when they are respectively fixed in their corresponding mounting grooves 41. The production tooling also includes a sealing block 5 that can be moved between a first position and a second position. In the second position, the sealing block 5 seals the top opening of the fixed oil pipe 3. In the first position, the sealing block 5 is released from sealing contact with the top opening of the fixed oil pipe 3. The specific operation is as follows: the core 2 is fixed by the first tooling 1. After the fixed oil pipe 3 is fixed in the mounting groove 41, air is added through the air inlet pipe 14, pressurizing the diaphragm 22 of the core 2 to expel the silicone oil inside the core 2. When the silicone oil stops being discharged, the air supply is stopped, and the silicone oil returns to a low level. When the oil level returns to the target scale value, the sealing block 5 (which acts like the sealing paper) is moved to seal the top openings of the two fixed oil pipes 3 (the sealing block is in the second position). The fixed oil pipe 3 is then quickly removed, completing the oiling operation. It should be noted that the amount of oil drop is controlled by a preset time, that is, after stopping the gas filling for a certain period of time, the sealing block 5 moves to the second position to seal the top open end of the fixed oil pipe 3. The specific time is obtained through a large number of experiments and analysis of the core oil storage capacity in the core 2; if necessary, a ruler can be used, or scale lines can be directly engraved on the second tooling 4 to review the remaining silicone oil amount in the fixed oil pipe 3 to ensure the accuracy of the fixed oil.

[0043] Therefore, in this embodiment, automatic oil control avoids the operational errors of manual oil setting (mainly because the oil amount is observed by eye, there is a reaction delay misunderstanding, and when the actual amount of oil setting deviates greatly from the required amount, it will cause product accuracy deviation, and in severe cases, the product will be scrapped), improves efficiency, and ensures the processing consistency of the core 2 product.

[0044] In other practical applications, such as Figure 2 and Figure 3As shown, based on the above-mentioned automated mechanical structure for oil determination, a slide groove 42 is also provided on the second tooling 4, and the end face of the top open end of the oil determination pipe 3 is flush with the bottom surface of the slide groove 42. The sealing block 5 is slidably connected in the slide groove 42 to realize its movement between the first position and the second position.

[0045] The second fixture 4 is also provided with a rotation drive source 43 and a gear 44 installed on the output shaft of the rotation drive source 43 . The gear 44 is meshed with the tooth grooves on the sealing block 5 , and the sealing block 5 is driven to move in the slide groove 42 by the rotation of the gear 44 .

[0046] In this embodiment, the sealing block 5 slides horizontally (perpendicular to the axial direction of the fixed oil pipe). After the two fixed oil pipes 3 are installed in the corresponding installation grooves 41, and the top open end of the fixed oil pipe 3 is flush with the bottom end of the slide groove 42, the gear 44 is driven to rotate by the rotating drive source 43, thereby driving the sealing block 5 to move to the action position, and then the sealing block 5 seals the tops of the two fixed oil pipes 3, so as to control the amount of silicone oil in the fixed oil pipe 3.

[0047] Based on the above, the second tooling 4 is further provided with an avoidance area 45 (such as Figure 1 ), the first tooling 1 and the core 2 mounted on the first tooling 1 are at least partially located in the avoidance area 45.

[0048] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
