Detailed Implementation
[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings.
[0035] Example 1
[0036] A device for detecting the tin content in a solution during circuit board manufacturing, such as Figures 1-6 As shown, it includes an isolation cylinder 1, a buffer base 2, a protective door 3, a positioning pin 4, a corrosion-resistant bottom cylinder 5, a fixing frame 6, a liquid inlet button 71, a liquid outlet button 72, a liquid storage mechanism 8, and a liquid dispensing mechanism 9. The buffer base 2 is provided at intervals on the bottom of the isolation cylinder 1. The protective door 3 is hinged at the rear of the isolation cylinder 1. Positioning pins 4 are symmetrically arranged on the front of the protective door 3. The fixing frame 6 is fixed to the bottom of the inner side of the isolation cylinder 1.

The liquid outlet button 72 is provided at the lower part of the front side of the isolation cylinder 1. The liquid storage mechanism 8 is provided on the isolation cylinder 1. The liquid dispensing mechanism 9 is provided between the isolation cylinder 1 and the corrosion-resistant bottom cylinder 5.
[0037] The liquid storage mechanism 8 includes an inlet pipe 81, a water pump 82, a first liquid level sensor 83, a filter plate 84, and a first ball solenoid valve 85. The inlet pipe 81 is located on the left side of the front part of the anti-corrosion bottom cylinder 5 and is connected to it. The water pump 82 is located on the lower left side of the outer front side of the anti-corrosion bottom cylinder 5. The water pump 82 cooperates with the inlet pipe 81. The first liquid level sensor 83 is fixedly connected to the middle of the inner rear side of the anti-corrosion bottom cylinder 5. The filter plate 84 is fixedly connected to the lower part of the inner side of the anti-corrosion bottom cylinder 5. The first ball solenoid valve 85 is located on the lower left side of the outer rear side of the anti-corrosion bottom cylinder 5 and is connected to it.
[0038] The liquid dispensing mechanism 9 includes an electric push rod 91, a liquid dispensing cylinder 92, a positioning frame 93, a connecting bow plate 94, an up button 95, and a down button 96. An electric push rod 91 is fixedly connected to the middle of the top of the anti-corrosion bottom cylinder 5. The electric push rod 91 slides through the anti-corrosion bottom cylinder 5 and is connected to the connecting bow plate 94. A positioning frame 93 is fixedly connected to the connecting bow plate 94. The liquid dispensing cylinder 92 is placed inside the positioning frame 93.

The down button 96 is located below the up button 95.
[0039] People press the main power switch to power on the detection device. The first liquid level sensor 83, with its slotted roller, is activated. First, the operator connects the inlet pipe 81 and presses the inlet button 71 once. The inlet button 71 sends a signal, which the control module receives and controls the water pump 82 to operate. The water pump 82 draws the solution into the anti-corrosion bottom cylinder 5 through the inlet pipe 81. The first liquid level sensor 83 monitors the water level. When the first liquid level sensor 83 detects a water level higher than the rated value in the control module, it sends a signal. The control module receives the signal and controls the water pump 82 to stop. Then, an appropriate amount of precipitant is added to the anti-corrosion bottom cylinder 5, and after a period of reaction, the lowering button 96 is pressed once. The lowering button 96 sends a signal, which the control module receives and controls the electric push rod 91 to extend. The electric push rod 91... The connecting bow-shaped plate 94 moves downward, which in turn moves the positioning frame 93 downward. The positioning frame 93 moves downward, which in turn moves the liquid collection cylinder 92 downward. The liquid collection cylinder 92 moves downward and fills in an appropriate amount of solution. Then, the up button 95 is pressed once. The up button 95 sends a signal, and after receiving the signal, the control module controls the electric push rod 91 to retract. The connecting bow-shaped plate 94 then moves the liquid collection cylinder 92 upward to reset via the positioning frame 93. The liquid collection cylinder 92 is removed for further processing of the solution. The drain button 72 is pressed once. The drain button 72 sends a signal, and after receiving the signal, the control module controls the first ball solenoid valve 85 to open for 1 minute. The first ball solenoid valve 85 stops limiting the corrosion-resistant bottom cylinder 5, and the solution is discharged. After 1 minute, the control module controls the first ball solenoid valve 85 to close.
[0040] Example 2
[0041] Based on Example 1, such as Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, it also includes a positioning liquid storage mechanism 10, which includes a fixed plate 101, a positioning guide post 102, a magnetic strip 103, a liquid outlet pipe 104, a sealing frame 105, a reset spring 106, a sealing base plate 107, a first pressure sensor 108, an electromagnetic block 109, a liquid-blocking baffle 1010, and a spring guide post 1011. Fixed plates 101 are provided on both the front and rear sides of the corrosion-resistant bottom cylinder 5. Positioning guide posts 102 are fixedly connected to the inner surface of the fixed plates 101. Magnetic strips 103 are provided inside the positioning guide posts 102. A liquid outlet pipe 104 is provided on the upper right side of the corrosion-resistant bottom cylinder 5 for liquid outlet. The tube 104 is connected to the liquid collection cylinder 92. An electromagnetic block 109 is slidably provided inside the positioning guide post 102. The electromagnetic block 109 cooperates with the magnetic strip 103. A sealing frame 105 is fixed between the electromagnetic blocks 109 on the front and rear sides. A sealing base plate 107 is slidably provided on the sealing frame 105. A return spring 106 is provided between the inside of the sealing base plate 107 and the inner side of the sealing frame 105. A first pressure sensor 108 is provided at the lower part of the electric push rod 91. Spring guide posts 1011 are symmetrically provided on the right side of the liquid collection cylinder 92. A liquid blocking baffle 1010 is slidably provided between the spring guide posts 1011 on the front and rear sides.
[0042] It also includes a testing mechanism 11, which comprises a positioning base plate 111, a testing box 112, a heating module 113, a second ball solenoid valve 114, a pressurized chlorine tank 115, an exhaust pipe 116, a second liquid level sensor 117, a lifting measuring plate 118, a limit post 119, a second pressure sensor 1110, and a testing button 1111. The positioning base plate 111 is located on the lower part of the outer right side of the corrosion-resistant base cylinder 5. The testing box 112 is fixedly connected to the top center of the positioning base plate 111. The heating module 113 is located on the lower part of the outer right side of the testing box 112, and the testing box 112 is located on the upper center. The second spherical solenoid valve 114 has a pressurized chlorine tank 115 on the top front side of the positioning base plate 111. The pressurized chlorine tank 115 is fixedly connected to and communicates with the detection box 112. The upper rear side of the detection box 112 has an exhaust pipe 116 that is connected to it. The lower rear side of the detection box 112 has a second liquid level sensor 117 fixedly connected to it. The bottom of the detection box 112 has limit posts 119 spaced apart. The lifting measuring plate 118 is slidably connected between the limit posts 119. The middle of the bottom of the detection box 112 has a second pressure sensor 1110 fixedly connected to it. The lower front side of the isolation cylinder 1 has a detection button 1111.
[0043] When the detection device is powered on, the first pressure sensor 108 starts working. Pressing the descent button 96 once sends a signal. After receiving the signal, the control module controls the electric push rod 91 to extend, causing the connecting bow plate 94 to move downward, thus moving the sealing frame 105 downward. Meanwhile, the electromagnetic block 109 slides within the positioning guide post 102. When an appropriate amount of solution is filled into the liquid collection cylinder 92, pressing the ascending button 95 once sends a signal. After receiving the signal, the control module controls the electric push rod 91 to retract. The electric push rod 91 retracts a certain distance and contacts the first pressure sensor 108. The first pressure sensor 108 sends a signal, and after receiving the signal, the control module controls the electromagnetic block 109 to be energized. The electromagnetic block 109 attracts the magnetic strip 103, thus limiting the sealing base plate 107. The connecting bow plate 94 then moves the positioning frame 93 upward, which in turn moves the liquid collection cylinder 92 downward. The liquid cylinder 92 moves upward, and the liquid collection cylinder 92 moves upward to contact the sealing frame 105. Then, the sealing base plate 107 makes the liquid collection cylinder 92 in a sealed state. The return spring 106 is compressed. The liquid collection cylinder 92 continues to move upward, so that the liquid blocking baffle 1010 contacts the liquid outlet pipe 104. The liquid outlet pipe 104 drives the liquid blocking baffle 1010 to move downward. The liquid blocking baffle 1010 stops moving downward and stops limiting the liquid collection cylinder 92. The solution is discharged through the liquid outlet pipe 104 and can be collected in a collection container for further processing. When the electric push rod 91 is fully retracted and reset, it no longer contacts the first pressure sensor 108. The first pressure sensor 108 sends a signal again. After receiving the signal, the control module controls the electromagnetic block 109 to stop. Due to the action of the return spring 106, the sealing base plate 107 also moves upward and resets to stop sealing. In this way, the liquid collection capacity of the liquid collection cylinder 92 can be controlled.
[0044] Initially, the second ball solenoid valve 114 does not limit the outlet pipe 104, but it does limit the pressurized chlorine tank 115 and the exhaust pipe 116. When the detection device is powered on, the second liquid level sensor 117 and the second pressure sensor 1110 begin to operate. The liquid-blocking baffle 1010 contacts the outlet pipe 104 and moves downwards, stopping the limitation on the liquid collection cylinder 92. The solution then flows through the outlet pipe 104 into the detection box 112. The second liquid level sensor 117 monitors the water level. When the second liquid level sensor 117 detects that the water level is higher than the rated value in the control module, it sends a signal. After receiving the signal, the control module controls the second ball solenoid valve 114 to rotate forward. The forward rotation limits the outlet pipe 104, while the second ball solenoid valve 114 does not limit the pressurized chlorine tank 115 and the exhaust pipe 116. The pressurized chlorine tank 115 discharges chlorine into the detection chamber 112, and then discharges it from the exhaust pipe 116. At the same time, after receiving the signal, the control module also controls the heating module 113 to work. The heating module 113 heats the detection chamber 112, and the solution is evaporated, causing the tin to fall onto the lifting measuring plate 118. The lifting measuring plate 118 contacts the second pressure sensor 1110, and the second pressure sensor 1110 sends a signal. After receiving the signal, the control module controls the second ball solenoid valve 114 to reverse and reset. People can then record the number sent by the second pressure sensor 1110. In this way, people can easily measure the tin content of the solution.
[0045] Example 3
[0046] Based on Examples 1 and 2, such as Figures 12-14 As shown, it also includes a sedimentation mechanism 12, which includes a sedimentation tank 121, a water flow sensor 122, a spray pipe 123, a servo motor 124, a drive shaft 125, a first transmission assembly 126, a bevel gear assembly 127, a second transmission assembly 128, and a stirring spiral plate 129. The sedimentation tank 121 is located on the upper left side of the outer front side of the corrosion-resistant bottom cylinder 5, the water flow sensor 122 is located on the upper part of the liquid inlet pipe 81, and the spray pipe 123 is located on the upper part of the inner side of the corrosion-resistant bottom cylinder 5. The spray pipe 123 and the sedimentation tank 125 are connected to the sedimentation tank 121. The sedimentation tank 121 is fixedly connected and communicated. A servo motor 124 is provided on the lower left side of the anti-corrosion bottom cylinder 5. A drive shaft 125 is connected to the output shaft of the servo motor 124. A bevel gear assembly 127 is rotatably provided on the lower left side of the anti-corrosion bottom cylinder 5. A first transmission assembly 126 is circumferentially connected between the bevel gear assembly 127 and the drive shaft 125. A stirring spiral plate 129 is rotatably provided at the bottom of the anti-corrosion bottom cylinder 5. A second transmission assembly 128 is provided between the lower circumferential part of the stirring spiral plate 129 and the bevel gear assembly 127.
[0047] It also includes an emission filtration mechanism 13, which includes a filter cylinder 131, a filter carbon plate 132, an opening and closing baffle 133, and a pressing bent rod 134. The filter cylinder 131 is provided on the upper right side of the outer rear side of the anti-corrosion bottom cylinder 5. The filter cylinder 131 is fixedly connected to and communicates with the exhaust pipe 116. The filter carbon plate 132 is provided circumferentially at intervals on the inner side of the filter cylinder 131. The opening and closing baffle 133 is hinged at the rear of the filter cylinder 131. The pressing bent rod 134 is symmetrically provided on the upper and lower sides of the outer side of the filter cylinder 131.
[0048] Initially, the precipitant tank 121 contains an appropriate amount of precipitant, which is discharged into the anti-corrosion bottom cylinder 5 through the spray pipe 123. When the detection device is powered on, the water flow sensor 122 starts working. Pressing the liquid inlet button 71 once sends a signal. After receiving the signal, the control module controls the water pump 82 to work. The water pump 82 draws the solution into the anti-corrosion bottom cylinder 5 through the liquid inlet pipe 81. The water flow sensor 122 detects the water flow and sends a signal. After receiving the signal, the control module controls the servo motor 124 to work. The servo motor 124 drives the drive shaft 125 to rotate. The rotation of the drive shaft 125 drives the first transmission assembly 126 to rotate. The rotation of the moving component 126 drives the bevel gear assembly 127 to rotate, which in turn drives the second transmission assembly 128 to rotate. The rotation of the second transmission assembly 128 drives the stirring spiral plate 129 to rotate, which stirs the solution and precipitant. When the first liquid level sensor 83 detects that the water level is higher than the rated value in the control module, the first liquid level sensor 83 sends a signal. After receiving the signal, the control module controls the water pump 82 to stop, and the water flow sensor 122 detects that the water is no longer flowing. The water flow sensor 122 sends a signal again, and after receiving the signal, the control module controls the servo motor 124 to turn off. In this way, the solution and precipitant can be fully mixed.
[0049] When chlorine gas is discharged from the exhaust pipe 116, the filter carbon plate 132 filters the chlorine gas. After the filter carbon plate 132 has been used for a period of time, the clamping rod 134 can be twisted to open the opening and closing baffle 133, remove the filter carbon plate 132, install a new filter carbon plate 132, close the opening and closing baffle 133 and twist the clamping rod 134. In this way, the chlorine gas can be filtered to avoid affecting the surrounding environment.
[0050] like Figure 1 , Figure 15 and Figure 16As shown, it also includes an electrical control box 7, which is embedded in the lower front left side of the isolation cylinder 1. The electrical control box 7 includes a switching power supply, a power module, and a control module. The switching power supply supplies power to the entire device. The power module is connected to the main power switch via a line. The control module and the power module are electrically connected. The control module is connected to a DS1302 clock circuit and a 24C02 circuit. The liquid inlet button 71, liquid outlet button 72, lower button 96, upper button 95, detection button 1111, first liquid level sensor 83, second liquid level sensor 117, first pressure sensor 108, second pressure sensor 1110, and water flow sensor 122 are all electrically connected to the control module.
