Description

Technical Field

[0001] The present invention relates to the technical field of product detection in the production process of a hair dryer, a full-function integrated detection machine in an intelligent manufacturing production line of a hair dryer and a detection method thereof. Background Art

[0002] A hair dryer is a small electrical appliance that can dry hair or other wet items. It does this by generating hot air to speed up the evaporation of moisture, thereby drying hair or other objects quickly. A hair dryer usually consists of a motor, a fan, and a heating element. When you turn on the hair dryer, the motor drives the fan to rotate, thereby creating airflow. At the same time, the heating element heats the air entering the hair dryer, making it hot. In this way, the hot air is blown out through the fan and can be directly aimed at the hair or other wet items to speed up the evaporation of moisture. Hair dryers usually have different power and temperature settings, and the wind force and hot air temperature can be adjusted as needed. Generally speaking, higher power and temperature can dry hair faster, while lower settings are suitable for gentle air drying or styling.

[0003] Hair dryers have a short-time heating function, so their starting power and peak power are generally more than 1000W. They are high-power electrical appliances, so there are very strict requirements for safety during use.

[0004] Common hair dryer testing items include wind pressure test, negative ion test, insulation withstand voltage test, etc., but the testing equipment and methods are single. A single test device only has a single detection function and cannot achieve comprehensive testing.

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0061] Embodiment 1

[0062] Reference Figures 1 to 9 A full-function integrated testing machine in a hair dryer intelligent manufacturing production line includes: a frame 1, on which an electric control device 2 and a control display screen 21 electrically connected to the electric control device 2 are arranged. The control display screen 21 is used as an information board, and the parameters and test data of the whole machine can be displayed on the control display screen 21; secondly, it is used as an operating element, that is, the user can operate through the button control or touch mode on the control display screen 21.

[0063] The power socket 11 is installed on the frame 1 and is used to provide power to the hair dryer 10. The power socket 11 is electrically connected to the electric control device 2, and the power socket 11 is connected to a power leakage short-circuit switch; the power leakage short-circuit switch can prevent line leakage in time, and will trip and cut off power when the leakage current reaches a certain value.

[0064] There are several inspection stations 12, and each inspection station 12 is provided with an independent product positioning tool 3 for placing the hair dryer 10; wherein, each inspection station 12 is provided with an independent product positioning tool 3, so that the full-function integrated inspection machine can inspect multiple hair dryers 10 at the same time, greatly improving the inspection efficiency.

[0065] Wind blocking mechanism 4, refer to Figure 2 , which is movably arranged on the frame 1 and can contact the hair dryer 10 on the product positioning tooling 3 to block the air inlet 104 of the hair dryer 10; the negative ion detection mechanism 5, which is movably arranged on the frame 1 and can be connected with the air outlet 103 of the hair dryer 10 and conduct; the wind pressure detection mechanism 6, which is movably arranged on the frame 1 and can be connected with the air outlet 103 of the hair dryer 10 and conduct; the insulation withstand voltage detection mechanism 7, which is electrically connected to the electronic control device 2 and is contactably connected to the shell of the hair dryer 10; the voltage, current and power detection instrument 8, which is electrically connected to the electronic control device 2 and is in communication connection with the electronic control device 2; the alarm indicator light mechanism 9, which is fixed on the frame 1 and is in communication connection with the electronic control device 2.

[0066] The above content is the basic structural scheme of the present invention, wherein the more specific structural schemes of each mechanism are as follows:

[0067] 1. Product positioning tooling 3: Reference Figure 2 to Figure 4 , Fig. 9 , including a fixed base 31, a movable limit bracket 32 ​​located above the fixed base 31, a tool lifting cylinder 33 acting on the movable limit bracket 32, a plurality of switch pneumatic fingers 34 arranged on the movable limit bracket 32, a tool cylinder 35 arranged on one side of the fixed base 31, and a switch block 36 fixed on the tool cylinder 35. Preferably, the switch pneumatic fingers 34 are located above the hair dryer 10, and the switch block 36 is located below the hair dryer 10.

[0068] It should be noted that the switch pneumatic finger 34 is mainly adapted to the button-type switch of the hair dryer 10, and the number of the switch pneumatic finger 34 can be one or more, and each of them is connected to an external control air source. When any switch pneumatic finger 34 needs to work, the corresponding external control air source is turned on, so that the switch pneumatic finger 34 operates and contacts the switch at the upper end of the hair dryer 10 to be detected, thereby realizing the switch / gear adjustment function of the upper switch.

[0069] On the other hand, the switch block 36 is mainly adapted to the toggle switch of the hair dryer 10, and the number of the switch block 36 can be one or more, and the switch block 36 is moved in the horizontal position by the tooling cylinder 35. When any switch block 36 needs to work, the tooling cylinder 35 is started, so that the switch block 36 runs and contacts the switch at the lower end of the hair dryer 10 to be tested, so as to realize the switch / gear adjustment function of the lower end switch.

[0070] Preferably, the movable limiting bracket 32 ​​includes a rectangular bracket body 321, and a plurality of limiting pressure blocks 322 disposed downward on the rectangular bracket body 321 and having semicircular grooves 3221. The rectangular bracket body 321 has a relatively regular shape, which is convenient for the transition connection between the front and rear structural members; the limiting pressure blocks 322 press against the upper end of the hair dryer 10 during operation, playing an effective limiting role to prevent the hair dryer 10 from leaving the detection position. It is worth mentioning that the handle portion 101 of the existing hair dryer 10 is cylindrical and easy for the user to hold, so the structure of the semicircular groove 3221 on the limiting pressure block 322 is adapted to the handle portion 101 of the hair dryer 10, forming a better limiting effect, and will not oppress the hair dryer 10. Furthermore, if the size of the handle part 101 of the hair dryer 10 is larger, the tooling lifting cylinder 33 will shorten the descending stroke when in use to prevent the limiting pressure block 322 from pressing the hair dryer 10; if the size of the handle part 101 of the hair dryer 10 is smaller, the tooling lifting cylinder 33 will lengthen the descending stroke when in use to prevent an excessively large gap from being generated between the limiting pressure block 322 and the hair dryer 10, resulting in a poor limiting effect.

[0071] Furthermore, the fixed base 31 includes a first fixed bracket 311 and a second fixed bracket 312, wherein the first fixed bracket 311 is used to support the handle portion 101 of the hair dryer 10, and the second fixed bracket 312 is used to support the head portion 102 of the hair dryer 10. The first fixed bracket 311 is provided with a through hole 3111 for the switch block 36 to pass through; on the other hand, the second fixed bracket 312 is provided with an air guide 3121, and a guide cover 3122 is provided at the air guide 3121. The air guide 3121 is aligned and connected with the air outlet 103 of the hair dryer 10 through the guide cover 3122, and the guide cover 3122 guides and converges the wind blown out of the air outlet 103 of the hair dryer 10, thereby preventing the occurrence of inaccurate test results due to wind turbulence.

[0072] 2. Wind blocking mechanism 4: Reference Figure 2 , including a plurality of interchangeable wind shields 41, and the movable limiting bracket 32 ​​is detachably connected to any wind shield 41. The hair dryers 10 on the market and produced in factories have various shapes and styles. Therefore, in order to make the wind shield mechanism 4 in a single device multi-purpose and adapt to different hair dryers 10, it has a plurality of replaceable wind shields 41, each of which has a different shape and is adapted to different hair dryers 10 to achieve a wind shielding effect.

[0073] 3. Negative ion detection mechanism 5: Reference Figure 2 , including a negative ion cylinder 51, a negative ion mounting bracket 52 acted upon by the negative ion cylinder 51, a negative ion detector 53 disposed on the negative ion mounting bracket 52, and a flow guide tube 54 connecting the negative ion detector 53 and the air outlet 103 of the hair dryer 10. Among them, the negative ion detector 53 is an outsourced part, and its use is relatively conventional, and will not be described one by one here. The negative ion cylinder 51 is activated to realize the position movement function of the negative ion mounting bracket 52 (negative ion detector 53).

[0074] 4. Wind pressure detection mechanism 6: Reference Figure 6 , including a wind pressure cylinder 61, a wind pressure mounting bracket 62 acted upon by the wind pressure cylinder 61, and a wind pressure detector 63 arranged on the wind pressure mounting bracket 62. Among them, the wind pressure detector 63 is an outsourced part, and its use is relatively conventional, which will not be described in detail here. The wind pressure cylinder 61 can realize the position movement function of the wind pressure mounting bracket 62 (wind pressure detector 63) by starting.

[0075] 5. Insulation withstand voltage testing mechanism 7: Refer to Figure 7 to Figure 9, including an insulation withstand voltage tester 71, a conductive detection block 72 connected to the insulation withstand voltage tester 71 through a cable 75, a pressure-resistant cylinder 73 acting on the conductive detection block 72, and a conductive detection probe 74 connected to the fixed base 31 and capable of abutting against the shell of the hair dryer 10. Among them, the insulation withstand voltage tester 71 is an outsourced part, and its use is relatively conventional. The insulation withstand voltage tester is a device that performs insulation strength tests on various high-voltage electrical equipment, electrical components, and insulating materials under power frequency or DC high voltage. The leakage current value is adjusted by the coarse adjustment and fine adjustment knobs, and the test voltage is automatically cut off when the leakage current exceeds the tolerance. The start of the pressure-resistant cylinder 73 can realize the position movement function of the conductive detection block 72, so that the conductive detection probe 74 is in contact with the conductive detection block 72 (circuit conduction) or separated (circuit disconnection).

[0076] More preferably, one of the conductive detection probes 74 is arranged at the end of the handle portion 101 of the hair dryer 10 and is always connected to the insulation withstand voltage tester 71, and the other conductive detection probes 74 are arranged at the intersection of the handle portion 101 of the hair dryer 10 and the head portion 102, so that a certain distance is left between the conductive detection probes 74, that is, the detection coverage area is larger (almost covering the entire handle portion 101 of the hair dryer 10), so that the detection result is more accurate.

[0077] 6. Air filter pressure reducing valve 13, refer to Figure 1 The frame 1 is also provided with an air filter pressure reducing valve 13, which is connected to the switch pneumatic finger 34 through an air pipe. The main function of the air filter pressure reducing valve 13 is achieved through two main components: a filter and a pressure reducing valve. The filter component is responsible for removing solid particles, liquids and other impurities in the air to protect subsequent equipment and systems from damage. The pressure reducing valve component is responsible for reducing the high-pressure gas to the required working pressure range to ensure that the equipment (switch pneumatic finger 34) can operate normally.

[0078] Embodiment 2

[0079] It should be noted that another technical solution is provided in this embodiment, a hair dryer 10 detection method, which is applied to the full-function detection integrated machine in the hair dryer 10 intelligent manufacturing production line as described above, referring to Figure 10 to Figure 14 , including the following steps:

[0080] S1. Place the hair dryer 10 to be tested into the product positioning fixture 3, power on the all-in-one testing machine, start the fixture lifting cylinder 33 and descend, so that the movable limiting bracket 32 ​​moves toward the fixed base 31 to clamp and limit the hair dryer 10; the descending stroke of the fixture lifting cylinder 33 is adjustable to meet the positioning requirements of hair dryers 10 of different sizes. Once the hair dryer 10 is clamped and limited by the product positioning fixture 3, it can provide an effective limiting effect, so that when the hair dryer 10 is started and various mechanisms are tested, the hair dryer 10 can be kept in a relatively stable position to ensure normal testing.

[0081] S2, connect the cable 75 of the hair dryer 10 to be tested to the power socket 11, select the model of the hair dryer 10 in the electric control device 2, call up the detection parameter setting of the hair dryer 10 to be tested, and assemble the wind blocking mechanism 4 with the wind blocking cover 41 adapted to the hair dryer 10 to be tested; wherein, the detection parameter setting of the hair dryer 10 is the data set in the electric control device 2, if a new product is added, the user can add or delete the preset detection parameter setting in the electric control device 2. In other words, each model of the hair dryer 10 has different production requirements, so there is a one-to-one corresponding detection parameter setting in the electric control device 2 of the detection device.

[0082] S3, early cut-off detection, the electronic control device 2 adjusts the output voltage of the power socket 11 to 110V-240V (the specific output voltage depends on the model of the hair dryer 10), starts the hair dryer 10 by switching the pneumatic finger 34 and / or the switch block 36, and records the cut-off time when the hair dryer 10 automatically shuts down; if the hair dryer 10 does not automatically shut down within the set early cut-off time T1, the electronic control device 2 cuts off the power supply circuit of the power socket 11.

[0083] When the hair dryer 10 is in use, if the voltage of the mains input is too high, in order to protect the hair dryer 10 from damage, it is necessary to quickly detect and cut off the circuit in advance to provide protection for the hair dryer 10 and prevent damage to internal components. Early cut-off detection is to detect whether the early cut-off function of the hair dryer 10 is operating normally before leaving the factory, and timely screen and eliminate defective products.

[0084] The early cutting time T1 can be set accordingly according to different models of hair dryers 10 .

[0085] S4, detection of power, current and voltage, starting the hair dryer 10 and switching the gears by means of the switch pneumatic finger 34 and / or the switch dial block 36, and recording the voltage, current and power data of the hair dryer 10 at each gear within the circuit detection time T2 by means of the voltage, current and power detection instrument 8.

[0086] Through the detection of power, current and voltage, firstly, the working state and performance of the power supply system of the hair dryer 10 can be evaluated. By measuring the power supply current, the output power, efficiency, stability and other information of the power supply system can be obtained to determine whether the power supply is working properly. The power supply current test can be used to evaluate the performance and reliability of the power supply system, and provide a reference for the production and maintenance of the hair dryer 10. Secondly, it can meet the comprehensive measurement needs of AC and DC current signals. With the popularization of various high-power power electronic equipment, it is necessary to observe the waveform and analyze the harmonics of AC and DC current signals, as well as measure the effective value, DC value, AC value and other parameters. Thirdly, it can realize the isolated measurement of current and the measurement of large current. The use of shunts, mutual inductors, current sensors and the like can realize the isolated measurement of current and expand the measurement range to large current. Fourthly, it can realize the automatic adjustment of voltage, current and power, and improve the accuracy of measurement.

[0087] In summary, the detection of power, current and voltage is mainly used to evaluate power supply performance, meet comprehensive measurement requirements, achieve isolation and large current measurement, and provide functions such as automatic adjustment and multi-machine communication. These detection purposes are helpful for the production, maintenance and performance evaluation of the hair dryer 10.

[0088] The circuit detection time T2 can be set accordingly according to different models of hair dryers 10 .

[0089] S5, negative ion detection, the wind pressure cylinder 61 is started to reset the wind pressure detector 63 and make space, the negative ion cylinder 51 moves the guide tube 54 to the air outlet 103 of the hair dryer 10, the hair dryer 10 is started and the negative ion function is turned on by switching the pneumatic finger 34 and / or the switch block 36, and the negative ion data of the hair dryer 10 within the negative ion detection time T3 is recorded by the negative ion detector 53.

[0090] In this step, the air pressure cylinder 61 is used to adjust the position of the guide tube 54 so that the guide tube 54 is docked with the air outlet 103 (such as the guide cover 3122) of the hair dryer 10 to prevent the air volume from escaping and causing inaccurate detection. When the negative ion detector 53 is moved into place, the negative ion detector 53 purchased externally is directly used to detect the negative ion content of the airflow ejected by the hair dryer 10.

[0091] The negative ion detection time T3 can be set accordingly according to different models of hair dryers 10 .

[0092] S6, wind pressure detection, the wind pressure cylinder 61 is started to move the wind pressure detector 63 to the air outlet 103 of the hair dryer 10, the hair dryer 10 is started and the gear is switched by the switch pneumatic finger 34 and / or the switch block 36, and the wind pressure data of the hair dryer 10 at each gear within the wind pressure detection time T4 is recorded by the wind pressure detector 63.

[0093] The wind pressure index is one of the main performance indicators of the hair dryer 10, which can reflect the wind speed and effect of the hair dryer 10, and is also an indicator that consumers pay more attention to. In this step, the wind pressure of the hair dryer 10 is directly detected by using an external wind pressure detector 63.

[0094] Furthermore, since each hair dryer 10 is set up differently, specifically, the time from being turned on to the maximum air pressure may be long or short, so when setting the air pressure detection time T4, it is necessary to ensure that the hair dryer 10 to be detected can be turned on to output the maximum air pressure within the T4 time period.

[0095] S7, backwash cleaning detection, start the hair dryer 10 and turn on the backwash cleaning function by switching the pneumatic finger 34 and / or the switch block 36, and record the negative pressure data of the hair dryer 10 within the backwash cleaning detection time T5 through the wind pressure detector 63.

[0096] Conventional hair dryers 10 are equipped with a filter at the air inlet 104 to intercept dust, hair and other impurities on the air flow path to keep the inside of the hair dryer 10 clean. However, when a certain amount of impurities accumulate on the filter, the user needs to remove the filter and clean it by himself, otherwise it will cause obstruction, affecting the air intake and air pressure, and the impurities will pollute the air flow, making the blown air easily carry bacteria and viruses, which is not good for the health of the user.

[0097] Therefore, the more multifunctional hair dryer 10 has a backwash cleaning function, so this function needs to be tested before leaving the factory. When the backwash cleaning function of the hair dryer 10 is turned on (the internal high-speed motor reverses), the airflow enters from the air outlet 103 and then sprays out from the air inlet 104. Therefore, the wind pressure detector 63 is also used to record the negative pressure wind pressure data of the hair dryer 10 (at the air outlet 103) during the backwash cleaning detection time T5, so as to compare whether the wind pressure under the backwash cleaning function meets the requirements of the preset parameters and determine whether the backwash cleaning function is qualified.

[0098] The backwash cleaning detection time T5 can be set accordingly according to different models of hair dryers 10.

[0099] S8, delayed-cut detection, the wind blocking hood 41 is pressed against the air inlet 104 of the hair dryer, the hair dryer 10 is started by the switch pneumatic finger 34 and / or the switch dial block 36, and the cut-off time is recorded when the hair dryer 10 automatically shuts down; if the hair dryer 10 does not automatically shut down within the set delayed-cut time T6, the electronic control device 2 cuts off the power supply circuit of the power socket 11.

[0100] The delayed cut-off detection simulates improper use by the user, that is, the user blocks the air inlet 104 and the internal heating element continues to heat. Due to insufficient air volume, the internal temperature of the hair dryer 10 will rise rapidly. If it is not disconnected in time, it is very easy to burn the internal components. Unqualified products will pose a great safety hazard.

[0101] During the delayed-cut detection process, once the internal temperature of the hair dryer 10 reaches the set temperature critical value and does not automatically shut down within the set delayed-cut time T6, it is determined that the delayed-cut function of the hair dryer 10 currently being detected is abnormal, and an NG signal is output; once the internal temperature of the hair dryer 10 reaches the set temperature critical value and can automatically shut down within the set delayed-cut time T6, it can be determined that the delayed-cut function of the hair dryer 10 currently being detected is normal.

[0102] The internal temperature of the hair dryer 10 is generally detected and controlled by a temperature control detection switch provided in the hair dryer 10 , and the specific temperature critical value is not particularly limited herein.

[0103] The delayed cutting time T6 can be set accordingly according to different models of hair dryers 10 .

[0104] S9, insulation withstand voltage test, the withstand voltage cylinder 73 is started to make the conductive detection block 72 contact with the conductive detection probe 74, the hair dryer 10 is started and the gear is switched by the switch pneumatic finger 34 and / or the switch block 36, then the insulation withstand voltage tester 71 is started and the voltage value on the housing of the hair dryer 10 is detected within the insulation withstand voltage test time T7, and the staff observes whether the appearance of the hair dryer 10 changes;

[0105] S10. In steps S3-S9, the detected data are compared with the qualified parameters preset for the hair dryer 10 model in the electric control device 2; if the data does not meet the qualified parameters, the electric control device 2 outputs an NG signal, and the alarm indicator mechanism 9 flashes red; if the data meets the qualified parameters, the electric control device 2 outputs an OK signal, and the alarm indicator mechanism 9 flashes green. The staff can observe whether the hair dryer 10 currently being tested is qualified through the alarm indicator mechanism 9, and can judge whether the hair dryer 10 currently being tested is qualified through the NG signal / OK signal output by the electric control device 2 (displayed on the control display screen 21). Then, the qualified hair dryers 10 and the unqualified hair dryers 10 are shipped separately.

[0106] S11. After the test of the hair dryer 10 is completed, the tooling lifting cylinder 33 is started and rises, so that the movable limit bracket 32 ​​moves away from the fixed base 31 to release the hair dryer 10. The staff unplugs the cable 75 from the power socket 11 and removes the hair dryer 10 on the product positioning tooling 3, and then puts a new batch of hair dryers 10 to be tested into the product positioning tooling 3 to start a new round of testing.

[0107] It should be noted that steps S3, S4 and S5 can be performed simultaneously, thereby eliminating the interval time between some detection items and shortening the overall detection time.

[0108] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment according to the technical essence of the invention still falls within the protection scope of the technical solution of the present invention.
