Description

Technical Field

[0001] The present invention relates to the technical field of product detection, and in particular to a contact-type temperature measuring device for a thermos cup. Background Art

[0002] After the thermos is produced, its heat preservation performance needs to be tested. Currently, the heat preservation performance of the thermos is usually tested by heating the inner wall and then testing the outer wall temperature. The detection methods in the prior art include: one is to use manual sampling, that is, manually place the thermos cup to be inspected on a heating table, heat the inside of the thermos cup, and then touch the outer shell of the thermos cup with a hand. If the outer shell does not heat up, it proves that the insulation performance is good and the heat inside the thermos cup is not transferred to the outside, then the thermos cup is judged to be qualified for insulation. Otherwise, it proves that the thermos cup is unqualified, and manual experience is needed to determine whether it is qualified. The other is to use an infrared temperature sensor. After heating the inside of the thermos cup for a certain period of time, a non-contact single-point infrared temperature sensor is used to measure the outer wall of the thermos cup. If the temperature of the outer wall is higher than the set value, it proves that the heat heated inside the thermos cup is transferred to the outer wall of the thermos cup, and the insulation performance of the thermos cup is unqualified. Otherwise, it proves that the thermos cup is qualified. One of the above two types relies on manual touch judgment, which has errors, and the other is a single-point temperature measurement of the outer wall of the thermos cup, which has the problem of incomplete measurement and inability to measure multiple areas of the thermos cup, which leads to inaccurate detection.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide a contact-type temperature measuring device for a thermos cup, so as to solve the problems existing in the above-mentioned prior art and improve the detection accuracy of the thermos cup.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] At present, when testing the thermal insulation performance of thermos cups, the human hand touch detection or infrared sensor single-point non-contact detection method used has low efficiency and is prone to inaccurate detection. In order to solve this problem, the present invention provides a contact temperature measurement device for thermos cups, such as Figures 1 to 6 As shown, it includes a frame 1, on which a closed conveyor chain group 5 is provided. The conveyor chain group 5 moves along the length direction of the frame 1. A mounting hole 502 is provided on the chain plate 501 of the conveyor chain group 5. The inverted thermos cup 7 can be placed on the mounting hole 502; a heating mechanism 6 is arranged in the frame 1, which has a vertically arranged air outlet pipe 605. When the mounting hole 502 drives the thermos cup 7 to move to just above the air outlet pipe 605, the heating mechanism 6 can blow hot air into the thermos cup 7 through the air outlet pipe 605, thereby increasing the internal temperature of the thermos cup 7 to simulate the state of holding hot water; an inlet temperature measuring mechanism 3 and an outlet temperature measuring mechanism 4 are respectively provided at the top two ends of the frame 1. Before heating, the temperature measuring mechanism 3 can clamp the outer wall of the thermos cup 7 on the conveyor chain group 5 and measure its temperature, and the dimensional value is transmitted to the control end; the outlet temperature measuring mechanism 4 can clamp the thermos cup 7 after heating on the conveyor chain group 5 and measure its temperature. The measured temperature value can be transmitted to the control end. The control end can detect the thermal insulation performance of the thermos cup 7 by comparing the two temperature differences. When the two temperature differences are within a reasonable range, it proves that the thermal insulation performance of the thermos cup 7 is good and the temperature inside the cup after being heated by hot air is not transmitted to the outer wall of the cup; if the two temperature differences are large and exceed the reasonable range, it proves that the thermal insulation performance of the thermos cup 7 is poor and the temperature inside the cup is transmitted to the outer wall of the cup. The control end uses a computer with a built-in known mature software program that can compare and analyze the two temperature measurement values. When unqualified products are detected, a signal can be sent in time to facilitate the subsequent removal of defective products.

[0034] In order to facilitate positioning during loading, an upper piece positioning baffle 2 is fixedly provided at one end of the top of the frame 1 near the inlet temperature measuring mechanism 3. The upper piece positioning baffle 2 is horizontally arranged on the top of the conveying chain group 5, and a plurality of arc-shaped positioning grooves are provided on the inner side of the upper piece positioning baffle 2; the vertical projection of the virtual circle where the plurality of arc-shaped positioning grooves are located can coincide one by one with the plurality of mounting holes 502 on the strip plate moved to the bottom of the upper piece positioning baffle 2. When the detection starts, the thermos cup 7 to be tested is arranged in accordance with the arc-shaped positioning groove, and the bottom opening of the thermos cup 7 can be placed on the mounting hole 502 on the chain plate 501 moved here.

[0035] In order to place the thermos cup 7 stably, the chain plate 501 of this embodiment adopts a plurality of strip plates hinged in sequence, and the plurality of strip plates are connected in sequence to form a ring, and a plurality of mounting holes 502 are provided on the strip plates. The opening of the thermos cup 7 can be stably buckled on the mounting hole 502, and an air outlet hole 505 is provided at the center of the mounting hole 502. An air return hole 506 is provided around the outer side of the air outlet hole 505. After the thermos cup 7 is buckled on the mounting hole 502, the thermos cup The opening of 7 can be buckled with the air outlet hole 505 and the return air hole 506, so that the air outlet pipe 605 can blow hot air into the thermos cup 7 through the air outlet hole 505 to achieve heating of the thermos cup 7. At the same time, after the hot air enters the bottom of the thermos cup 7, it flows downward through the inner wall of the cup and is discharged through the return air hole 506 arranged around the outer side of the air outlet hole 505, avoiding excessive high pressure of the hot air in the cup. In order to achieve smooth transportation of the thermos cup 7, the conveying chain group 5 of this embodiment includes a first The sprocket 503, the second sprocket 504 and the chain plate 501 are provided with two equal-height first sprockets 503 above the frame 1, and two equal-height second sprockets 504 are provided below the frame 1. One end of the closed chain plate 501 is connected to a closed chain, and the chain is closed and wound around the first sprocket 503 and the second sprocket 504; one of the second sprockets 504 is connected to a driving motor for transmission, so that the driving motor rotates, which can drive the second sprocket 504 to rotate, and then drive the chain to rotate, and the chain can drive the chain plate 501 to rotate. When the strip plate of the chain plate 501 rotates between the two first sprockets 503, it is in a horizontal state. This is the working position of the chain plate 501. At this time, the thermos cup 7 can be placed and transported. The position of the inlet temperature measuring mechanism 3 is set at one end of the frame 1 and close to the position of one of the first sprockets 503; the outlet temperature measuring mechanism 4 is located at the other end of the frame 1 near the other first sprocket 503. In order to make the operation of the chain plate 501 more stable, a closed chain is provided on both sides of the chain plate 501, and the two chains have their own corresponding first sprocket 503 and second sprocket 504, so that the two ends of the chain plate 501 are synchronously driven by the two chains, and the operation is more stable; when the inspection of the thermos cup 7 is completed, a temporary storage table is set at the end of the frame 1, and the inspected thermos cup 7 can be placed on the temporary storage table for subsequent manual or mechanical hands to store good and defective products separately. After the thermos cup 7 is placed on the temporary storage table, the chain will bypass the position of the first sprocket 503 there and drive the chain plate 501 to continue to rotate downward, and finally return to the position of the first sprocket 503 near the inlet temperature measuring mechanism 3, so that the chain plate 501 can be re-participated in placing the thermos cup 7 for inspection.

[0036] In order to improve the heating efficiency, the heating mechanism 6 of this embodiment includes a heating box 601 fixedly arranged in the frame 1, and a heating device is arranged in the heating box 601. The heating device of this embodiment adopts an electric heating pipe 603; an air outlet box 602 is arranged in the heating box 601, and the air outlet box 602 is relatively small and is located above the electric heating pipe 603. A heating circulation fan 604 is arranged at one end of the heating box 601, and the air inlet of the heating circulation fan 604 is communicated with the interior of the heating box 601, and the air outlet of the heating circulation fan 604 is communicated with the interior of the air outlet box 602, so the heating circulation fan 60 4 can send the hot air heated by the electric heating tube 603 in the heating box 601 into the air outlet box 602; a plurality of air outlet ducts 605 are arranged in a row along the length direction of the rack 1, and the number of air outlet ducts 605 in each row is the same as the number of mounting holes 502 on the strip plate. After the top opening of the air outlet duct 605 passes through the top of the heating box 601, it can be in contact with the bottom of the air outlet hole 505 to achieve simultaneous heating of the interior of multiple thermos cups 7 in each row; a return air duct opening 606 is opened on the top of the heating box 601, and the return air duct opening 606 surrounds the The top of the air outlet 605 is connected to the bottom of the air return hole 506, and the top opening of the air outlet 605 passes through the top of the heating box 601 and is at the same height as the top of the heating box 601, so that there is no large height difference between the top opening of the air outlet 605 and the return air channel opening 606. In a preferred embodiment, there is no height difference between the two. The top of the air outlet 605 is connected to the bottom of the air outlet hole 505 moved thereto, and hot air can be sent to the thermos cup 7 through the air outlet hole 505. The return air channel opening 606 is connected to the return air hole 506, and the inside of the thermos cup 7 is connected to the return air hole 506. After the hot air circulates, it will enter the return air channel opening 606 through the return air hole 506, and finally enter the heating box 601, and participate in the next circulation after reheating; in order to avoid the wind force being too small, the return air channel opening 606 and the return air hole 506 are not sealed and connected, and there is a gap between the two, so under the suction of the heating circulation fan 604, in addition to the hot air in the thermos cup 7 circulating and entering the return air channel opening 606 through the return air hole 506, some of the outside air will also enter the heating box 601 through the return air channel opening 606, be heated, and then enter the heating circulation fan 604.

[0037] The inlet temperature measuring mechanism 3 of this embodiment includes an inlet temperature measuring frame 301 fixed to one end of the top of the frame 1, and the inner sides of the two side walls of the inlet temperature measuring frame 301 are provided with a vertically arranged lifting slide 8, and a slider is provided on the lifting slide 8, and the slider is connected to a slider driving mechanism, and the slider driving mechanism is a driving motor.

The clamp parallel cylinder 9 can drive the two sensor clamps 10 to move toward or away from each other. When the two clamp parallel cylinders 9 move toward each other, the arc-shaped clamping grooves corresponding to the two clamps can be clamped on the side wall of the thermos cup 7, thereby fixing the thermos cup 7. A plurality of sensor contacts 11 are provided at different positions of the arc-shaped clamping groove, so that the plurality of sensor contacts 11 can contact-detect the temperature at different positions of the side wall of the thermos cup 7. The detection accuracy is improved by detecting multiple points. The sensor contact 11 adopts a contact temperature sensor, which can measure the temperature of the outer wall of the thermos cup 7 after contacting the outer wall of the thermos cup 7.

[0038] The outlet temperature measuring mechanism 4 of this embodiment has the same principle as the inlet temperature measuring mechanism 3, except that the outlet temperature measuring mechanism 4 also includes an outlet transfer slide 401 arranged on the top of the frame 1 away from one end of the inlet temperature measuring frame 301, and the outlet transfer slide 401 is arranged on both sides of the conveyor chain group 5 and arranged along the length direction of the frame 1, and the end of the outlet transfer slide 401 is located above the temporary storage table; a sliding seat is provided on the outlet transfer slide 401, and the seat is driven by a horizontal cylinder, a hydraulic cylinder or a screw nut pair and can move horizontally, and an outlet temperature measuring frame 402 is fixed on the seat; the inner sides of the two side walls of the outlet temperature measuring frame 402 are provided with a vertically arranged lifting slide 8, and a slider is provided on the lifting slide 8, and the slider is connected to a slider driving mechanism; a plywood parallel cylinder 9 is provided on the slider, and the plywood parallel cylinder 9 is connected to two symmetrically arranged The sensor clamp 10 is arranged, and an arc-shaped clamping groove is provided on the inner side of the sensor clamp 10.

The arc-shaped clamping groove is provided with a sensor contact 11, which is the contact of the temperature sensor. The sensor contact 11 can detect the temperature of the side wall of the thermos cup 7. When the heated thermos cup 7 moves to a position close to the exit transfer slide 401, the base drives the exit temperature measuring rack 402 to move to the thermos cup 7 and clamps the heated thermos cup 7. Then, after it is detached from the mounting hole 502, it is moved to the position above the temporary storage table. At this time, the secondary temperature measurement starts. After the temperature measurement is completed, the clamped thermos cup 7 can be placed on the temporary storage table.

[0039] In order to better distinguish qualified good products from unqualified defective products, in a preferred embodiment, a marking actuator 12 is provided on one of the sensor clamps 10 of the outlet temperature measuring mechanism 4. The marking actuator 12 includes a telescopic cylinder fixed to the outside of the arc-shaped clamping groove. The end of the cylinder rod of the telescopic cylinder is connected to a benchmark. The benchmark is engraved with a marking pattern at the end away from the telescopic cylinder. The marking pattern is coated with paint. The telescopic cylinder is connected to the control end. The two temperature measurement data are input into the mature software of the control end for comparison and analysis. When the control end finds defective products, it can control the corresponding telescopic cylinder to extend. The control process adopts a mature numerical control method, and then the telescopic cylinder can drive the benchmark to print the marking pattern on the side wall of the unqualified thermos cup 7, so that the side wall of the unqualified thermos cup 7 is printed with an unqualified pattern, which is convenient for subsequent distinction.

[0040] When the present invention is working, the above positioning baffle 2 is used as a reference to place the thermos cup 7 to be tested; after placement, the mature control program of the control end is used to advance the conveyor chain group 5 for one beat to reach the initial measurement inlet temperature measuring mechanism 3, and the slider of the inlet temperature measuring mechanism 3 is lowered to the set height. The sensor clamping plate 10 is tightened to the inner side of the thermos cup 7 under the action of the clamping plate parallel cylinder 9, so that the contact of the temperature sensor is in close contact with the outer wall of the thermos cup 7, and the initial temperature data is collected and stored. Then the clamping plate parallel cylinder 9 is released, the slider rises and resets, and waits for the next A row of products; after the initial temperature measurement, the products arrive at the heating position and start to be heated. During the heating process, the electric heating tube 603 heats the air, and the heating circulation fan 604 blows the hot air into the air outlet box 602, and then blows it out from the air outlet pipe 605, into the interior of the thermos cup 7. After the interior of the thermos cup 7 is filled, it overflows along the return air hole 506 into the return air channel 606, and then enters the heating box 601, and is heated again by the electric heating tube 603. The cycle is repeated to keep the thermos cup 7 filled with hot air that has reached the set temperature. The heating is repeated six times. Figure 6 The arrows in the figure indicate the hot air circulation state. After six heating cycles, there are three natural static positions without interference. At this time, the conveyor chain group 5 is stationary, simulating the process of the thermos cup 7 being filled with hot water for three minutes and the heat naturally conducting to the shell of the thermos cup 7.

[0041] After the rest time is over, the thermos cup 7 enters the secondary temperature measurement position, that is, the outlet temperature measurement position, the slider of the outlet temperature measurement mechanism 4 drops to the set height, the clamping plate parallel cylinder 9 works, and pushes the installed sensor contact 11 to closely contact the outer wall of the thermos cup 7, collects and stores the temperature data of the secondary temperature measurement, and then the clamping plate parallel cylinder 9 does not release, the slider drives the clamped thermos cup 7 to rise to the set transfer height, the outlet transfer slide 401 works, so that the outlet temperature measurement mechanism 4 moves the thermos cup 7 as a whole horizontally, and the thermos cup 7 is transferred to the next process conveyor line as a whole. In this embodiment, it is transferred to the temporary storage at the end of the rack 1. At the storage station, when the outlet temperature measuring mechanism 4 moves the product to the designated position, the data processor at the control end processes the temperature measurement data collected twice before and after, determines whether the multiple thermos cups 7 corresponding to each column are qualified, and gives instructions to the marking actuator 12. For unqualified thermos cups 7, the corresponding marking actuator 12 is actuated and an unqualified label is applied to them. Similarly, qualified products are not marked. When the marking is completed, the entire temperature measurement process is completed. At this time, the splint parallel cylinder 9 in the outlet temperature measuring mechanism 4 is released, the slider rises and resets, and at the same time the outlet transfer slide 401 returns and resets, waiting for the next process, and so on.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
