In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0035] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0036] like Figure 1As shown, an embodiment of the utility model relates to a low-temperature oscillating trimming machine suitable for the inner ring of a perfluoroether O-ring, comprising a stand 1, on which a cryogenic tube 2 and an operating mechanism 3 are provided. The outer peripheral wall of the cryogenic tube 2 is suitable for sleeved with an O-ring. One end of the cryogenic tube 2 is connected to the operating mechanism 3, and the other end is connected to the stand 1. The machine also comprises a driving member 4 for driving the operating mechanism 3 to rotate and driving the cryogenic tube 2 to rotate. The stand 1 is also provided with a nitrogen channel 5, which is connected to the cryogenic tube 2. Perfluoroether O-ring products involved in the semiconductor field have very high surface requirements. For small-sized O-rings (for example, ID less than 5mm), the inner ring is difficult to repair. Using low-temperature cooling to remove burrs can easily damage the surface of the inner ring of the product in the process. This tooling takes into account both the protection of the product at room temperature and the removal of burrs in the low-temperature working area, effectively solving this problem. During application, the small-sized perfluoroether O-ring product is first sleeved on the cryogenic tube 2, the inner ring of the small-sized perfluoroether O-ring product contacts the cryogenic tube 2, and nitrogen enters the cryogenic tube 2 through the nitrogen pipeline, so that the cryogenic tube 2 is in a low-temperature state. Then, the driving member 4 drives the operating mechanism 3 to rotate, and the operating mechanism 3 drives the cryogenic tube 2 to rotate to generate centrifugal force, so that the small-sized perfluoroether O-ring product sleeved on the cryogenic tube 2 performs centrifugal motion, and the burrs can be removed under the premise of protecting the small-sized perfluoroether O-ring product.

[0037] In the low-temperature oscillating trimming machine provided by the utility model, Figure 3 The operating mechanism 3 includes a first rotating wheel 31, a second rotating wheel 32, and a belt 33. The belt 33 is used to connect the first rotating wheel 31 and the second rotating wheel 32. The first rotating wheel 31 is connected to the driving member 4, and the second rotating wheel 32 is connected to the cryogenic tube 2. During operation, the driving member 4 drives the first rotating wheel 31 to rotate, and the transmission is transmitted to the first rotating wheel 31 via the belt 33. The first rotating wheel 31 also rotates, thereby driving the cryogenic tube 2 connected to the first rotating wheel 31 to rotate.

[0038] In the low-temperature oscillating trimming machine provided by the present invention, the driving component 4 may be, for example, a motor.

[0039] In the low-temperature oscillating trimming machine provided by the present invention, the low-temperature tube 2 includes a first tube body 21, a second tube body 22, and a third tube body 23 connected in sequence. The first tube body 21 and the second tube body 22 are detachably connected, and the second tube body 22 and the third tube body 23 are detachably connected. The detachable connection facilitates the placement of the O-ring product on the low-temperature tube 2.

[0040] Furthermore, the first tube body 21 and the third tube body 23 are respectively arranged parallel and perpendicular to the second tube body 22, and the second tube body is parallel to the bottom of the stand.

[0041] Furthermore, the detachable connection can be fixed and detached by screws, for example. Specifically, the first tube body 21 and the second tube body 22 are detachably connected by screws, and the second tube body 22 and the third tube body 23 are detachably connected by screws.

[0042] In the low-temperature oscillating trimming machine provided by the present invention, an exhaust fan is also provided on the stand 1 .

[0043] In the low-temperature oscillation trimming machine provided by the present invention, in order to better realize automatic control, it also includes a control unit. The low-temperature tube 2 is provided with a temperature detector, and the nitrogen channel 5 is provided with a flow valve 6. The control unit includes a controller and an operation panel. The operation panel is provided on the stand 1. The control unit is respectively connected to the drive member 4, the temperature detector, and the flow valve 6 by signal.

[0044] The control unit is a conventional controller. Those skilled in the art will appreciate that the controller's calculation, comparison, judgment, and command output processes can all be implemented using integrated circuit modules, programmable logic devices, other hardware, or by installing corresponding software modules in the prior art. The control unit is used to input and display various parameters and automatically adjust the nitrogen valve flow rate to control temperature. The parameter setting table on the operation panel includes the upper temperature limit, lower temperature limit, set speed, and set time. The parameter display table includes the actual temperature, rotation countdown, ammeter, actual nitrogen flow rate, etc.

[0045] The temperature of cryogenic tube 2 is detected by a temperature detector. When the temperature of cryogenic tube 2 is above or below a set temperature range, the temperature detector feeds back a temperature signal to the control unit. The control unit receives the signal and sends an adjustment signal to the liquid nitrogen valve to adjust the valve size, thereby adjusting the liquid nitrogen flow rate. When the temperature reaches the average of the brittle temperature and the glass transition temperature, the rotary button is turned on. The temperature detector feeds back the temperature signal to the control unit, which sends a drive signal to a drive element. After receiving the drive signal, the drive element, such as a motor, drives the operating mechanism 3 to rotate, thereby driving the rotation of cryogenic tube 2, causing the small-sized perfluoroether O-ring product to undergo centrifugal motion, thereby trimming the inner ring of the O-ring without causing collisions between adjacent O-rings.

[0046] The working process of the low-temperature oscillation trimming machine of this utility model:

[0047] 1. Check whether the surface of the cryogenic tube 2 is smooth. After the inspection is completed, put the perfluoroether small-size O-ring product on the second tube body 22 of the cryogenic tube 2, and then install the second tube body 22 symmetrically with the first tube body 21 and the third tube body 23 respectively, and fix them with bolts.

[0048] 2. Set the temperature, speed, and operation time. The temperature should be higher than the brittle temperature of the material and lower than the glass transition temperature Tg of the material.

[0049] 3. Open the flow valve, and liquid nitrogen enters the cryogenic tube 2 through the liquid nitrogen pipeline. The liquid nitrogen flow rate will be adjusted in time through the control unit according to the temperature feedback.

[0050] 4. When the temperature reaches the average value of the brittle temperature and the glass transition temperature, turn on the rotation button, and then use the control unit to drive the motor to drive the first rotating wheel 31 to rotate. The transmission is transmitted to the first rotating wheel 31 through the belt 33. The first rotating wheel 31 also rotates, thereby driving the low-temperature tube 2 connected to the first rotating wheel 31 to rotate, so that the low-temperature tube 2 and the perfluoroether small-size O-ring product are in working state (i.e., performing centrifugal motion).

[0051] 5. After the rotation time is over, turn off the liquid nitrogen valve, open the exhaust system (exhaust fan), put on gloves, and when the temperature reaches room temperature, turn off the rotation button, remove the cryogenic tube 2, remove the sample, and clean the cryogenic tube 2.

[0052] 6. Return the cryogenic tube 2 to its original position. Figure 1 .

[0053] In summary, the low-temperature oscillating trimming machine provided in the embodiment of the present invention is suitable for trimming the inner rings of small-sized perfluoroether O-rings. By utilizing the heat conduction effect of low-temperature nitrogen, the centrifugal force is generated when the O-ring product rotates around the cryogenic tube 2, so that the inner ring of the O-ring product can be evenly stressed and heat-transferred. When the temperature is above the brittle temperature (below the glass transition temperature), the flash can be removed while protecting the product without damaging other adjacent O-ring products.

[0054] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
