In the production process of smart toilets, the final process includes assembly, testing, cleaning and other processes. However, due to the weight of smart toilets, repeated handling in different processes will greatly reduce production efficiency, waste manpower and operation time, and it is difficult to achieve high efficiency and achieve the goal of automated production. If the assembly, aging test, safety inspection, water removal, cleaning and other processes of smart toilets are designed on the same intelligent production line, this will greatly improve production efficiency, save time, and reduce the labor intensity of workers; at the same time, in order to improve the recycling and reuse of test water, it is also a current problem. Summary of the invention
[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a smart toilet assembly and testing line with good detection effect, simple structure, convenient recycling of detection water and strong practicality.
[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a smart toilet assembly and testing line, comprising a frame and a conveying track arranged on the frame, the frame being provided with a loading circulation lifting platform, a plurality of assembly stations, a grounding resistance detection station, a semi-finished product leakage detection station, a semi-finished product performance detection station and a unloading circulation lifting platform in sequence, the frame being provided with a drainage recovery mechanism arranged on the semi-finished product leakage detection station, the drainage recovery mechanism comprising a suction chamber arranged on the frame, a piston arranged in the suction chamber, a driving cylinder for driving the piston to reciprocate in the suction chamber, a water collecting tank arranged below the conveying track, a first connecting pipe connected to the suction chamber at one end and placed in the water collecting tank at the other end, a first on-off valve arranged on the first connecting pipe, a second connecting pipe connected to the other side of the suction chamber and having an output end connected to the drain port of the toilet to be inspected, and a second on-off valve arranged on the second connecting pipe.
[0005] The present invention is further configured as follows: the driving cylinder is connected to a buffer oil circuit, which includes a hydraulic tank, a hydraulic pump arranged in the hydraulic tank, a pressure-relief oil circuit structure and a three-position four-way reversing valve. The three-position four-way reversing valve includes port A, port B, port P and port T. Port A is connected to the rod chamber of the driving cylinder, port B is connected to the rodless chamber of the driving cylinder, port T is connected to the hydraulic pump, port P is the oil return port, and the pressure-relief oil circuit structure is arranged between the three-position four-way reversing valve and the hydraulic pump.
[0006] The present invention is further configured as follows: the pressure relief oil circuit structure includes a piston pressure relief valve and an on-off valve, the piston pressure relief valve includes an A port, a P port and a T port, the A port of the piston pressure relief valve is connected to the T port of the three-position four-way reversing valve, the P port of the piston pressure relief valve is connected to the hydraulic pump, one end of the on-off valve is connected to the T port of the piston pressure relief valve, the other end of the on-off valve is placed in the hydraulic groove, and a pressure relief valve core is provided in the valve cavity of the piston pressure relief valve.
[0007] The present invention is further configured as follows: the pressure-relief valve core divides the valve cavity into an output cavity and a pressure-relief cavity; the pressure-relief valve core includes a table-shaped portion located in the output cavity and a plane portion located in the pressure-relief cavity; the table surface area of the table-shaped portion is smaller than that of the plane portion; a plurality of through holes connecting the output cavity and the pressure-relief cavity are provided on the pressure-relief valve core; a pressure-relief spring is provided in the pressure-relief cavity.
[0008] The present invention is further configured such that when the pressure relief valve core seals the port A of the piston pressure relief valve, the ratio of the axial length of the pressure relief cavity to the axial length of the piston pressure relief valve cavity occupied by the valve core is between 2 / 3 and 3 / 4.
[0009] By adopting the above technical scheme, the beneficial effects are as follows: 1. In order to improve the recovery and recycling of the detection water, a drainage recovery mechanism is provided on the frame and arranged on the semi-finished product leakage detection station, and the drainage recovery mechanism is arranged to include a suction chamber arranged on the frame, a piston arranged in the suction chamber, and a driving cylinder for driving the piston to reciprocate in the suction chamber. By adopting the above structural arrangement, the driving cylinder drives the piston as a power source, and then a suction effect is formed in the suction chamber to accelerate the detection speed. At the same time, through a water collecting pool arranged under the conveying track, a first connecting pipe connected to the suction chamber at one end and placed in the water collecting pool at the other end, a circulation treatment effect is formed through the water collecting pool and the first connecting pipe, and then through a second connecting pipe connected to the other side of the suction chamber and the output end connected to the drain port of the toilet to be detected, a first on-off valve arranged on the first connecting pipe and a second on-off valve arranged on the second connecting pipe are formed, so that the piston absorbs and discharges water from the suction chamber, thereby accelerating the detection effect;
[0010] 2. By connecting the driving oil cylinder with a buffer oil circuit, the speed is gradually slowed down when the piston is pumping, which is convenient for forming the suction stability during the suction, ensuring that the water can fill the suction chamber, thereby ensuring a good circulation and water pressure detection effect;
[0011] 3. By setting the pressure relief oil circuit structure to include a piston pressure relief valve and an on-off valve, the piston pressure relief valve includes an A port, a P port and a T port, the A port of the piston pressure relief valve is connected to the T port of the three-position four-way reversing valve, the P port of the piston pressure relief valve is connected to the hydraulic pump, one end of the on-off valve is connected to the T port of the piston pressure relief valve, and the other end of the on-off valve is placed in the hydraulic groove, and a pressure relief valve core is provided in the valve cavity of the piston pressure relief valve, because the pressure relief valve core divides the valve cavity into an output cavity and a pressure relief cavity, the pressure relief valve core includes a table-shaped part located in the output cavity and a plane part located in the pressure relief cavity, the table area of the table-shaped part is smaller than the plane part, and a plurality of through holes connecting the output cavity and the pressure relief cavity are provided on the pressure relief valve core, and a pressure relief valve core is provided in the pressure relief cavity. There is a pressure-relief spring. When the on-off valve is closed, the pressure-relief spring provides a force to the pressure-relief valve core, so that the pressure-relief spring closes the A port of the piston pressure-relief control valve; when the through-end valve is opened, the pressure-relief chamber is depressurized. When the hydraulic pump supplies oil, because less hydraulic oil enters the through hole, the pressure-relief valve core is pushed open, and the hydraulic oil flows out from the A port of the piston pressure-relief valve, forming the oil supply of the oil circuit, realizing the suction effect of the piston, and then by closing the on-off valve, the subsequent slow suction of the hydraulic cylinder is realized. Similarly, when the reversing valve is started, the on-off valve is opened again, the hydraulic pump is started, the hydraulic pressure is reversed, the piston rod is reset, and then the on-off valve is closed to achieve the pressure-relief effect. It has strong practicality and simple structure.
[0012] A detection method applicable to the above-mentioned smart toilet assembly detection line includes the following steps: (1) automatic production: using the ground resistance detection station, it is necessary to turn the blocking direct rotation button to the open position, when the movement flows to this station and the movement rises, connect the red clip to the grounding pin of the leakage plug, and then press the start test on the touch screen. After the detection is completed, the ground resistance detection instrument will make a beeping sound and ask you to remove the red connection line. In the case that there is no movement at the printing barcode station, when the movement flows to this station, the movement flows directly to the printing barcode station;
[0013] (2) Movement data storage: When the movement data is directly stored, print the barcode station and turn on the blocking direct rotation button. When the movement flows to this station, the operator generates two copies of the barcode according to the configuration of the movement, one for the cover staff and one on the movement. Then use the barcode scanner to scan the current barcode. After the barcode is successfully scanned, the data is automatically stored and the first line of data is deleted on the touch screen, and the cylinder is automatically released;
[0014] (3) Movement data storage: When the movement data is not directly stored, the barcode printing station will turn on the blocking direct rotation button. When the movement flows to this station, manually copy the data of the unqualified movement or write a qualified mark and stick it on the movement. Then, take the movement away, press the release button, and wait for the next movement to arrive;
[0015] (4) Check whether the material is in place: When the number of empty positions displayed on the computer monitor is not equal to zero, press the red stop button first to stop the upper belt and then put the movement on the upper belt. The movement will automatically move to the station where the movement is needed and stop. The touch screen of the corresponding station will display that the movement has arrived;
[0016] (5) Cover operation: When the computer monitor shows that there is a workstation calling for cover or the movement inspection is about to be completed, search for the cover first according to the movement barcode on the table. After the inspection, press the red stop button to stop the upper belt and then put the cover on the upper belt. Then use the barcode scanner at this workstation to scan the barcode on the cover. After that, the upper belt will start running, move the cover to the required workstation and stop. The touch screen of the corresponding workstation will display that the cover has arrived.
[0017] (6) Leakage and performance testing: Control the temperature and water pressure to test the leak prevention and performance of the toilet, and record the number of qualified and unqualified ones respectively;
[0018] (7) Packaging and unloading.
[0019] By adopting the above technical scheme, the beneficial effect is achieved. The present invention is an improvement of the production process, and the traditional workstation production in the customer's factory is combined into an assembly line, which is a fully automatic assembly line integrating production, assembly, coding, testing, aging, packaging, transportation, and warehousing. All workstations are neatly arranged in appropriate positions, and each workstation is assigned a worker to operate. This saves labor costs compared to the original workstations. The mechanical automated assembly line is simple to operate, and the workers work more easily. The toilet cover and the movement can be transmitted through the belt in the middle of the assembly line, saving transportation time. They can be transported to the designated workstation, and then the workers take them down and put them in the workstation for aging or testing. The toilet cover and the movement are paired in the form of barcode scanning, which greatly reduces the error rate of manual search. The detection equipment communicates with the computer configuration software, directly transmits the detection data value to the computer configuration software for display and saves it in the database, and the historical bill can be queried at any time. If there is a fault in the production process, the fault can also be saved in the database, so that the next time the fault occurs again, it can be checked whether it has been repaired at that time.
