Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of thermos cup production and testing equipment, specifically to an energy-saving thermos cup vacuum degree testing device. Background Technology
[0002] The heat preservation performance of a thermos cup mainly depends on the degree to which it isolates the contents from the heat of the external environment. When testing the heat preservation performance of a thermos cup, which is also the vacuum degree of the cup wall, it is necessary to heat the inside of the thermos cup and measure the temperature of the outer wall to determine its heat preservation performance.
[0003] According to the invention patent application with publication number CN110726752B and publication date of 2024-12-10, a thermos cup testing device is disclosed, including a hot air blower, a circulating air duct, a control valve, and a testing chassis. The circulating air duct includes a first air duct and a second air duct. The hot air blower has an air outlet for blowing out hot air and an air inlet for drawing in hot air. The air outlet is connected to the first air duct, and the air inlet is connected to the second air duct. The testing chassis has an air outlet for blowing out hot air and an air inlet for drawing in hot air. Both the first and second air ducts are connected to the control valve. The first air duct is connected to the air outlet through the control valve, and the second air duct is connected to the air inlet through the control valve. The control valve can control the first and second air ducts to be connected to each other and close the air inlet and air outlet, or the first and second air ducts to be disconnected and the air inlet and air outlet to be opened. Its main technical effect is that the circulating air duct formed by the first and second air ducts controlled by the control valve connects the air outlet and air inlet of the hot air blower, avoiding energy loss and blower damage caused by switching the hot air blower on and off.
[0004] In existing technologies, hot air is used to test the vacuum degree and heat preservation performance of thermos cups. However, the hot air needs to be kept on continuously during the test, resulting in high energy consumption. Therefore, an energy-saving thermos cup vacuum degree testing device is proposed to solve the problem of high energy consumption in existing technologies that use hot air for vacuum degree testing. Utility Model Content
[0005] The purpose of this invention is to provide an energy-saving vacuum testing device for thermos cups, aiming to solve the problem of high energy consumption in existing technologies that use hot air for vacuum testing.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An energy-saving vacuum cup testing device includes a frame and a robotic arm, as well as a heating water tank disposed inside the frame and a testing unit disposed on the frame. The robotic arm is equipped with a temperature sensor. The testing unit includes a base and an expansion bladder. The base is fixedly installed on the frame, and the expansion bladder is fixedly connected to the base. The base is connected to the heating water tank, and a water pump is disposed between the base and the heating water tank.
[0008] Preferably, an inner tube is fixedly installed on the base, and the inner tube has several water-permeable holes. The expansion bladder is fixedly installed on the outside of the inner tube, and the inner tube is connected to the heating water tank.
[0009] Preferably, the system also includes a connecting valve, which is fixedly installed inside the frame. One end of the connecting valve is connected to the base, and the other end is connected to the water pump. The end of the water pump away from the connecting valve is connected to the heating water tank.
[0010] Preferably, the outer wall of the expansion bladder is provided with an exhaust groove.
[0011] Preferably, the robotic arm is equipped with a visual inspection probe.
[0012] The above-mentioned technical solution provides an energy-saving vacuum testing device for thermos cups, which has the following beneficial effects:
[0013] This invention uses a water pump to deliver hot water from a heating tank to a base, which then delivers it to an expansion bladder. The expansion bladder expands and adheres to the inner wall of the thermos, thus heating the thermos. After testing, a robotic arm removes the thermos from the base. Because the expansion bladder is heated by hot water from the heating tank, and the hot water can be recycled after heating, energy consumption is significantly reduced. At the same time, a temperature sensor on the robotic arm can detect the temperature of the outer wall of the thermos, allowing the robotic arm to test the thermos's insulation performance while removing the thermos, greatly improving the efficiency of thermos testing.

Detailed Implementation
[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] Please see Figure 1 —6, an energy-saving thermos cup vacuum degree testing device, including a frame 1 and a robot arm 2, and also including a heating water tank 3 set inside the frame 1 and a test unit 4 set on the frame 1. The robot arm 2 is equipped with a temperature sensor 5. The test unit 4 includes a base 41 and an expansion bladder 42. The base 41 is fixedly installed on the frame 1, the expansion bladder 42 is fixedly connected to the base 41, the base 41 is connected to the heating water tank 3, and a water pump 6 is provided between the base 41 and the heating water tank 3.
[0025] The robotic arm 2 is a conventional robotic arm in the prior art. It can grasp insulated cups and place them on or remove them from the testing unit 4. The robotic arm 2 enables automatic loading and unloading of insulated cups. Several testing units 4 are arranged in an array on the frame 1. As a further embodiment of this utility model, such as... Figure 1 As shown, there are two sets of test units 4, both of which are linearly arrayed on the rack 1. The linear array distribution of the test units 4 allows for the simultaneous testing of multiple thermos cups, thus improving testing efficiency.
[0026] Test unit 4 includes a base 41 and an expansion bladder 42. The base 41 is fixedly connected to the frame 1 by bolts and is connected to the heating water tank 3. The expansion bladder 42 is fixedly installed on the base 41. Specifically, the expansion bladder 42 is made of one piece of rubber and can expand to a certain extent. The base 41 is connected to the heating water tank 3, and a water pump 6 is provided between the base 41 and the heating water tank 3. The water pump 6 can draw hot water from inside the heating water tank 3 and transport it into the expansion bladder 42 in the base 41, thereby allowing the expansion bladder 42 to... The expansion bladder 42 expands and adheres to the inner wall of the thermos cup to be tested. The expansion bladder 42 heats the thermos cup by adhering to the inner wall. When the robotic arm 2 grasps the thermos cup, the temperature sensor 5 on the robotic arm 2 detects the temperature of the outer wall of the thermos cup. If the temperature sensor 5 detects a temperature exceeding a certain value, it indicates that the vacuum layer of the thermos cup is damaged, and heat can be transferred from the inside of the thermos cup to the outer wall, meaning the thermos cup's insulation performance is substandard. Subsequently, the control unit can control the robotic arm 2 to place the substandard thermos cup at a designated location. Preferably, the temperature sensor 5 is located on the gripper part of the robotic arm 2.
[0027] It should be noted that the liquid inside the heating water tank 3 can be water or other liquids with good thermal conductivity.
[0028] To improve detection accuracy, multiple temperature sensors 5 can be set.
[0029] It should be noted that using robotic arm 2 to grab the thermos cup and place it at the designated location is a conventional technical method in the prior art, and will not be elaborated here.
[0030] After the test is completed, the hot water inside the expansion bladder 42 can be pumped back into the heating water tank 3 by the water pump 6, which reduces the heat loss of the hot water outside the heating water tank 3, thereby reducing energy consumption and improving economic efficiency.
[0031] It should be noted that the dimensions of the base 41 and the expansion bladder 42 can be designed according to the production of different models and sizes of thermos cups. Furthermore, the base 41 is fixedly connected to the frame 1 by bolts, so that different sizes of base 41 and expansion bladder 42 can be replaced when it is necessary to change the model of thermos cups to be produced.
[0032] This utility model uses a water pump 6 to transport hot water from the heating tank 3 to the base 41, and then from the base 41 to the expansion bladder 42. This causes the expansion bladder 42 to expand and fit against the inner wall of the thermos cup, thus heating the thermos cup. After testing, the thermos cup is removed from the base 41 by a robotic arm 2. Because the expansion bladder 42 is heated by the hot water from the heating tank 3, and the hot water can be recycled after heating, energy consumption can be greatly reduced. At the same time, the temperature sensor 5 on the robotic arm 2 can detect the temperature of the outer wall of the thermos cup, thus enabling the robotic arm 2 to test the thermos cup's insulation performance while removing the cup, greatly improving the efficiency of thermos cup testing.
[0033] As a further embodiment provided by this utility model, such as Figure 2 As shown, an inner tube 43 is fixedly installed on the base 41. Several water-permeable holes 44 are formed on the outer wall of the inner tube 43. The inner tube 43 is connected to the water pump 6 through the bottom of the base 41. An expansion bladder 42 is fixedly installed outside the inner tube 43. During use, the water pump 6 draws hot water from the heating water tank 3 and delivers it to the base 41. The hot water then enters the expansion bladder 42 through the water-permeable holes 44 on the inner tube 43, causing the expansion bladder 42 to expand and adhere to the inner wall of the thermos. After testing, the water pump 6 pumps the water inside the expansion bladder 42 back into the heating water tank 3, causing the expansion bladder 42 to contract, making it easier for the expansion bladder 42 to be inserted into the next thermos. Simultaneously, the recovered water is reheated to ensure the water temperature meets requirements for the next test. Furthermore, since the recovered water already has a certain temperature, the energy consumption required for heating in the heating water tank 3 is reduced, achieving energy saving.
[0034] As a further embodiment provided by this utility model, such as Figure 4 As shown, it also includes a connecting valve 7, which is installed inside the frame 1. Specifically, the connecting valve 7 is fixedly installed outside the heating water tank 3. The connecting valve 7 is connected to the base 41 and the water pump 6 respectively. The opening and closing of the connecting valve 7 can be controlled by the control module. The connecting valve 7 is connected to multiple bases 41 through connecting pipes 9.
[0035] As an embodiment provided by this utility model, such as Figure 1As shown, multiple bases 41 are arranged in two rows on the frame 1. There are two water pumps 6 and two connecting valves 7. The two connecting valves 7 and the water pumps 6 are symmetrically arranged. One of the connecting valves 7 is a three-way valve. The connecting pipes 9 include a first main pipe 91, a second main pipe 92, a connecting branch pipe 93, and an auxiliary connecting pipe 94. Specifically, the first main pipe 91 and the second main pipe 92 are connected to both ends of one of the connecting valves 7. The other end of one of the connecting valves 7 is connected to the water pump 6. There are several connecting branch pipes 93. One end of each of the several connecting branch pipes 93 is connected to the first main pipe 91 or the second main pipe 92, and the other end is connected to a single base 41. The connecting branch pipe 93 has multiple ports. The connecting branch pipe 93 is connected to the first main pipe 91, the second main pipe 92, and several connecting branch pipes 93 through the multiple ports. The connecting branch pipe 93 is connected to another connecting valve 7.
[0036] To further reduce heat loss, insulation material can be wrapped around the outer wall of the connecting pipe 9 to reduce heat loss during hot water flow.
[0037] By using two sets of water pumps 6 and connecting valves 7, multiple bases 41 can be filled or pumped out simultaneously to improve testing efficiency.
[0038] It should be noted that the design of the connecting pipe 9 is not limited to the one mentioned above. It is acceptable as long as it can be connected to the base 41 and can be used to transport water through the water pump 6 and to pump water from the base 41 back into the heating water tank 3.
[0039] As an embodiment provided by this utility model, such as Figure 3 As shown, an venting groove 45 is provided on the outer wall of the expansion bladder 42. Through the design of the venting groove 45, when the expansion bladder 42 expands inside the thermos, the air inside the thermos can escape through the venting groove 45, thus ensuring that the expansion bladder 42 can fit snugly against the inner wall of the thermos. In actual use, the movement state of the expansion bladder 42 is referenced... Figure 6 , Figure 5 and Figure 3 This process involves the expansion of the material from its initial state to its final fit against the inner wall of the thermos.
[0040] As an embodiment of the present invention, a vision detection probe 8 is provided on the robotic arm 2. The robotic arm 2 can perform visual detection on the thermos cup through the vision detection probe 8 and grasp it, which helps the robotic arm 2 to accurately pick up and put down the thermos cup and insert the thermos cup into the base 41.
[0041] It should be noted that the visual inspection probe 8 installed on the robotic arm 2 is existing technology. Visual recognition and object grasping through the visual inspection probe 8 is a conventional technical means in the existing technology. Its specific structure and principle will not be described in detail here.
[0042] Working principle:
[0043] The robot arm 2 identifies and picks up the thermos cup using the vision detection probe 8, and then inserts the thermos cup into the base 41.
[0044] Then, the hot water inside the heating water tank 3 is extracted by the water pump 6 and transported to the inner tube 43 of the base 41 through the connecting valve 7 and connecting pipe 9, which inflates the expansion bladder 42 so that the expansion bladder 42 fits against the inner wall of the thermos cup to heat the thermos cup.
[0045] Then, the water pump 6 recovers the hot water inside the expansion bladder 42 into the heating water tank 3. Then, the robotic arm 2 removes the thermos cup from the base 41. When the temperature sensor 5 on the robotic arm 2 comes into contact with the outer wall of the thermos cup, it can detect the temperature. When the detected temperature exceeds a certain value, it indicates that the vacuum layer of the thermos cup is damaged, and heat can be transferred from the inside of the thermos cup to the outer wall of the insulation. That is, the insulation performance of the thermos cup is unqualified. Then, the control unit can control the robotic arm 2 to place the unqualified thermos cup in a designated location, and the qualified thermos cup can also be placed in a designated location by the robotic arm 2.
[0046] Those skilled in the art will understand that other similar connection methods can also achieve this utility model. For example, welding, bonding, or screwing.
[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
