Description

Technical Field

[0001] The present invention relates to the technical field of thermostat production, and in particular to a thermostat setting fine-tuning device and a thermostat production line. Background Art

[0002] A thermostat is a series of automatic control components that physically deform within a switch in response to ambient temperature changes, producing specific effects and switching the device on or off. These components are also called temperature-controlled switches, temperature protectors, temperature controllers, or simply thermostats. Alternatively, the temperature protector transmits the temperature to the temperature controller, which then issues a switch command, thereby controlling the device's operation to achieve the desired temperature and energy savings. Thermostats have a wide range of applications, including applications in home appliances, motors, refrigeration, heating, and other products, depending on the type of thermostat.

[0003] The Chinese invention patent application document with publication number CN114899044A discloses a liquid expansion thermostat structure, including a thermostat body, a liquid-sealed power system and a temperature adjustment component.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0036] On the one hand, if Figure 1 and Figure 2 、 Figure 3 、 Figure 4 As shown, a temperature controller setting fine-tuning device in one embodiment of the present invention, the temperature controller includes a temperature control body 101, a temperature sensing tube and a capillary connecting the temperature control body 101 and the temperature sensing tube, the temperature control body 101 is provided with a liquid-sealed power system, and an input adjustment shaft 102 for adjusting the temperature control range, the setting fine-tuning device includes a constant temperature device 1, a setting fine-tuning device 2 and a signal processing device 3; the constant temperature device 1 is provided with a constant temperature water tank 11 for placing the temperature sensing tube of the thermostat, the setting fine-tuning device 2 includes a placement seat 21, a locking component 22, an adjustment component 23 and an output component; the input adjustment shaft 102 is provided with an adjusting nut 103 for adjusting the hydraulic pressure of the liquid-sealed power system.

[0037] like Figure 3 and Figure 4 As shown, by improving the thermostat structure, an adjusting nut 103 for adjusting the hydraulic pressure of the liquid-sealed power system is positioned on the input adjustment shaft 102. Rotation of the adjusting nut 103 causes the input adjustment shaft 102 to move along its centerline, thereby controlling the hydraulic pressure of the liquid-sealed power system using the top contact point at the top of the input adjustment shaft 102 as the set point. This thermostat has a simple structure and strong continuous operability in actual production, facilitating improved efficiency in thermostat setting and fine-tuning.

[0038] The above-mentioned thermostat setting fine adjustment device is configured by placing the thermostat temperature sensing tube into the constant temperature water tank 11, placing the temperature control body 101 into the mounting limit groove of the placement seat 21, and locking the temperature control body 22 onto the placement seat 21. After a predetermined time has passed and the constant temperature water tank 11 has heated the thermostat temperature sensing tube to a preset temperature, the adjustment component 23 rotates the adjustment nut 103 of the input adjustment shaft 102 so that the top end of the input adjustment shaft 102 presses against the liquid-sealed power system. The signal processing device 3 receives the temperature signal sent by the temperature control body 101, compares the temperature signal of the thermostat with the preset heating temperature value of the constant temperature device 1, and thereby sends an adjustment signal to the adjustment component 23. The adjustment component 23 rotates the adjustment nut 103 to adjust the reference pressure value of the liquid-sealed power system, thereby adjusting the temperature control reference value of the thermostat. The entire setting fine adjustment process is highly automated, saving time and effort. Human error is reduced during the setting process, thereby facilitating improved setting accuracy of the thermostat.

[0039] Specifically, after the temperature-sensing tube is placed in a constant-temperature water bath 11 and soaked for a period of time, the top of the input adjustment shaft 102 is twisted to its highest point and then held stationary. The thermostat is then controlled on and off by adjusting the adjustment nut 103 on the input adjustment shaft 102. In case one, if the thermostat is on, the adjustment nut 103 is driven downward, moving the input adjustment shaft 102 until the thermostat is just off, and then stopping. In case two, if the thermostat is off, the adjustment nut 103 is driven upward, turning the thermostat on, and the steps in case one are repeated.

[0040] like Figure 3 and Figure 4 As shown in one embodiment, the adjustment assembly includes an adjustment drive 231, an adjustment transmission unit 232, an adjustment drum 233, and a fixed shaft drum 234 coaxially connected to the adjustment drum 233. The fixed shaft drum 234 is provided with a positioning hole adapted for the input adjustment shaft 102. The adjustment drum 233 is provided with a stopper adapted for the adjustment nut 103. After the input adjustment shaft is inserted into the positioning hole, the input adjustment shaft is connected to the hub of the fixed shaft drum 234. Thus, the adjustment drive 231 drives the adjustment drum 233 to rotate via the adjustment transmission unit 232, thereby driving the adjustment nut 103 and the input adjustment shaft 102 to rotate relative to each other. Since the adjustment nut 103 is rotationally connected to the temperature control body 101, it can only rotate and cannot move, thereby causing the input adjustment shaft 102 to move up and down along the central axis. The temperature control reference value of the thermostat is adjusted by changing the contact position of the top end of the input adjustment shaft 102.

[0041] In one embodiment, the input adjustment shaft 102 and the fixed axis cylinder 234 utilize a limiting guide unit to restrict the circumferential displacement of the input adjustment shaft 102. The limiting guide unit comprises an axially beveled surface on the input adjustment shaft 102 and a limiting inner wall on the fixed axis cylinder 234, the limiting inner wall aligning with the axial beveled surface. Thus, the axial beveled surface and the limiting inner wall cooperate to constrain the input adjustment shaft 102, once inserted into the fixed axis cylinder 234, to move only up and down along its central axis, preventing rotation.

[0042] In one embodiment, the end surface of the adjusting nut 103 is provided with a positioning notch, and the upper surface of the adjusting drum 233 is provided with a positioning protrusion adapted to the positioning notch. In this way, the adjusting drum 233 and the adjusting nut 103 are connected to the hub by the cooperation of the positioning protrusion and the positioning notch.

[0043] In one embodiment, the fixed-axis cylinder 234 is fixedly connected to the placement seat 21, and the adjusting rotary cylinder 233 is rotatably connected to the fixed-axis cylinder 234 via a first bearing unit 235. The adjusting rotary cylinder 233 is rotatably connected to the placement seat 21 via a second bearing unit 236. In this way, the first bearing unit 235 and the second bearing unit 236 ensure stable rotation of the adjusting rotary cylinder 233 during fine-tuning of the setting, thereby improving the setting accuracy of the thermostat.

[0044] In one embodiment, the locking component 22 includes at least two locking assemblies, and the adjusting component 23 includes at least two adjusting assemblies. The placement seat 21 is provided with at least two mounting limit slots. This allows for multiple sets of locking and adjusting assemblies to work together, facilitating fine-tuning of temperature control reference values ​​for multiple thermostats, further improving the efficiency of thermostat fine-tuning.

[0045] In one embodiment, the locking assembly includes a locking driver 221 and a locking pressure block 222 that is driven by the locking driver 221 to move up and down. The locking pressure block 222 is adapted to fit the temperature control body. Specifically, the locking pressure block 222 has an elastic contact surface adapted to fit the outer shell of the temperature control body 101.

[0046] In one embodiment, the temperature controller is provided with a mounting bend edge, and the mounting limit groove is adapted to accommodate the mounting bend edge; the locking drive 221 is a pneumatic cylinder, and the adjustment drive 231 is a servo motor. Specifically, the output portion of the temperature control body 101 is provided with a contact electrode head, and the placement seat 21 is provided with an electrode contact. Thus, the mounting bend edge defines the placement position of the temperature control body 101 within the mounting limit groove, and the locking pressure block 222 is pressed against the contact electrode head of the temperature control body 101 by the pneumatic cylinder to close contact with the electrode contact, thereby ensuring that the temperature control body 101 can stably transmit temperature signals to the temperature control body 101.

[0047] In one embodiment, the constant temperature device 1 further includes a mounting bracket 12 and a heating component. The constant temperature water tank 11 is disposed on the mounting bracket 12 . The heating component is used to heat the water in the constant temperature water tank 11 at a constant temperature.

[0048] The working principle of the thermostat setting fine adjustment device is as follows:

[0049] By placing the temperature controller temperature sensing tube into the constant temperature water tank 11, the temperature control body 101 is placed into the installation limit groove of the placement seat 21, and the locking component 22 locks the temperature control body onto the placement seat 21; after a predetermined time has passed and the constant temperature water tank 11 heats the temperature controller temperature sensing tube to a preset temperature, the adjusting component 23 rotates the adjusting nut 103 of the input adjusting shaft 102 so that the top end of the input adjusting shaft 102 presses the liquid-sealed power system, and the signal processing device 3 receives the temperature signal sent by the temperature control body 101, thereby sending an adjustment signal to the adjusting component 23, and the adjusting component 23 rotates the adjusting nut 103 to adjust the reference pressure value of the liquid-sealed power system, thereby adjusting the temperature control reference value of the thermostat.

[0050] On the other hand, Figure 5 As shown, a temperature controller production line in one embodiment of the present invention includes a conveying device 4 and a temperature controller setting fine-tuning device; the conveying device 4 is used to move the temperature controller body to the placement seat 21.

[0051] In one embodiment, the conveying device 4 includes a conveying device 5 and a conveying robot 6; the conveying device 5 includes a conveying component and a material moving component 51, the conveying component is used to convey the temperature control body to the loading position, and the material moving component 51 is used to move the temperature control body at the loading position to the placement seat 21; the conveying robot 6 clamps the capillary of the temperature controller and places the temperature-sensing tube into the constant temperature water tank 11. Specifically, the conveying component includes a conveying track. In this way, the temperature control body is conveyed to the loading position by the conveying component, and the material moving component 51 moves the temperature control body at the loading position to the placement seat 21, and the conveying robot 6 clamps the capillary of the temperature controller and places the temperature-sensing tube into the constant temperature water tank 11, thereby realizing the loading action of the temperature controller.

[0052] In one embodiment, the conveying device 4 further includes a material unloading robot, which clamps the capillary tube of the thermostat to remove the temperature-sensing tube from the constant-temperature water tank 11. Thus, after the temperature control reference value of the thermostat is set, the locking component 22 releases the temperature control body, and the material unloading robot clamps the capillary tube of the thermostat to remove the temperature-sensing tube from the constant-temperature water tank 11.

[0053] like Figure 5 and Figure 6As shown, in one embodiment, the locking component 22 includes two locking assemblies, the adjusting component 23 includes two adjusting assemblies, the placement seat 21 is provided with two mounting limit slots, and the conveying track is provided with a first loading position and a second loading position; the material moving component 51 includes a material moving seat 52, four material moving fixtures 53 spaced apart on the material moving seat 52, a lifting and lowering material moving assembly 54 that drives the material moving seat 52 to move up and down, a conveying and lowering material moving assembly 55 that drives the lifting and lowering material moving assembly 54 to move along the conveying direction of the conveying track, and a horizontal material moving assembly 56 that drives the conveying and lowering material moving assembly 55 to move perpendicular to the conveying direction of the conveying track. Specifically, the first loading position and the second loading position are spaced apart by a first distance value, and the distance between adjacent material moving fixtures 53 and the distance between the two mounting limit slots are equal to the first distance value. In this way, by setting four material transfer jigs 53 at intervals on the material transfer seat 52, and utilizing the four material transfer jigs 53 to be divided into two material transfer groups, the two temperature control bodies on the first loading position and the second loading position are moved to the two installation limit slots respectively, and at the same time, the two temperature control bodies that have been set and fine-tuned are moved out of the two installation limit slots. The structure is simple and reliable, and it is convenient to improve the setting and fine-tuning efficiency.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.

[0055] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
