Description

Technical Field

[0001] The utility model relates to the field of semiconductors, in particular to a tin stripping machine. Background Art

[0002] At present, the detinning operation of products is all controlled manually. The manually controlled detinning operation will result in the inability to monitor the detinning time in real time. When the detinning time is too short, the detinning will not be clean; when the detinning time is too long, the copper material will be corroded after detinning. Therefore, when the staff performs the detinning operation, the detinning time must be strictly controlled. The detinning time must not be too short or too long. However, the subjective judgment of the staff cannot accurately control the time. Secondly, when the temperature of the chemical is too high, the copper material will be corroded after detinning. Therefore, the detinning temperature also needs to be strictly controlled and cannot exceed 35 degrees. However, the temperature of the detinning cannot be strictly controlled by the measurement of the thermometer alone. Therefore, it is necessary to design a machine that can automatically detinn, which can realize the automation of detinning and ensure the quality of detinned products. Summary of the invention

[0030] In this embodiment, the feeding mechanism 7 includes: a feeding area 71, a pushing area 72 and an empty material box placement area 73. The feeding area 71, a feeding conveyor belt 74 is arranged along the feeding area 71, the pushing area 72 and the empty material box placement area 73, a material box (not shown in the drawings) is placed on the feeding conveyor belt 74, the feeding area 71 is used to place the product 6 that needs to be detinned into the material box, the pushing area 72 is used to move the product 6 out of the feeding mechanism 7, and the empty material box placement area 73 is used to place the empty material box.

The receiving area 92 is used to receive the tested product 6, the discharging area 91 is used to convey the qualified product 6 out of the tin stripping machine, and the product to be confirmed area 93 is used to store the unqualified product 6.

[0031] In this embodiment, an alarm device (not shown in the drawings) is also included. When the tin stripping process is abnormal, the alarm device sounds an alarm and stops the ongoing process. The alarm device includes a first alarm device arranged in the feeding mechanism 7 and a second alarm device arranged in the unloading mechanism 9. When the tin stripping process is abnormal, the first alarm device and the second alarm device are triggered to sound an alarm and stop the process, prompting the staff to perform timely maintenance.

[0032] In this embodiment, the first pushing mechanism 81 is used to clamp the product 6 in the pushing area 72 to the conveying device 1, and the second pushing mechanism 82 is used to clamp the inspected product 6 to the unloading mechanism 9. The product 6 that needs to be detinned is placed in the material box on the conveyor belt in the feeding area 71, and is transported to the pushing area 72 by the loading conveyor belt 74. The first pushing mechanism 81 clamps the product 6 to the conveyor 1, and the remaining empty material box in the pushing area 72 is further transported to the empty material box placement area 73 by the loading conveyor belt 74. After the product 6 after the detinning process is inspected by the inspection device 5, it is transported to the receiving area 92 by the second pushing mechanism 82, and the qualified product 6 is transported to the discharging area 91 by the unloading conveyor belt 94, and the unqualified product 6 is transported to the product confirmation area 92 by the unloading conveyor belt 94 for further inspection.

[0033] In this embodiment, the tin stripping tank 21 includes an upper tin stripping tank 211 and a lower tin stripping tank 212, and the upper tin stripping tank 211 and the lower tin stripping tank 212 are connected by a liquid inlet pipe 221 and a liquid outlet pipe 222. The tin stripping liquid can circulate between the upper tin stripping tank 211 and the lower tin stripping tank 212 through the liquid inlet pipe 221 and the liquid outlet pipe 222, and the product 6 that needs to be stripped can be placed in the upper tin stripping tank 211 for tin stripping. The tin stripping liquid located in the lower tin stripping tank 212 is input into the upper tin stripping tank 211 through the liquid inlet pipe 221, and the tin stripping liquid located in the upper tin stripping tank 211 is input into the lower tin stripping tank 212 through the liquid outlet pipe 222, thereby completing the circulation of the tin stripping liquid in the upper tin stripping tank 211 and the lower tin stripping tank 212.

[0034] In this embodiment, the process parameter monitoring unit includes a tin stripping time monitoring sensor 23 and a temperature sensor 24 .

[0035] If the product 6 is removed from the tin stripping device 2 before the set time point, that is, the tin stripping time is too short, it will lead to incomplete tin stripping, so that there will still be tin layer residue on the surface of the product 6. If the product 6 is removed from the tin stripping device 2 after the set time point, that is, the tin stripping time is too long, side reactions will occur, corroding the copper substrate of the product to cause thin feet, reducing the reliability of the product. Therefore, the utility model monitors the tin stripping time by setting a tin stripping time monitoring sensor 23, thereby ensuring the tin stripping quality and reliability of the product. The tin stripping time monitoring sensor 23 includes a first probe 231 and a second probe 232 arranged on the product transmission path. The tin stripping machine uses the time difference between the product passing through the first probe 231 and the second probe 232 to monitor the tin stripping processing time of the product 6. The tin stripping machine is also equipped with a time control device for setting the tin stripping time of the product. The dual protection of the time control device and the tin stripping time monitoring sensor 23 prevents the product from being incompletely stripped due to too short tin stripping time, and the product from being excessively corroded due to too long tin stripping time.

[0036] If the temperature of the tin stripping solution is too high, a side reaction will occur, corroding the copper substrate of the product to cause thin feet. Therefore, the present invention provides the temperature sensor 24 to monitor the temperature of the tin stripping solution. In some embodiments, the temperature sensor 24 is provided in the tin stripping lower tank 212.

[0037] In some embodiments, the tin stripping device 2 also includes a condensation component 25, which is arranged in the tin stripping lower tank 212 and is used to adjust the temperature of the tin stripping liquid. This prevents the tin stripping liquid in the tin stripping tank 21 from rising sharply due to continuous tin stripping, causing side reactions, corroding the copper substrate to cause thin feet, and then causing the product 6 to be scrapped. When the temperature sensor 24 detects that the temperature of the tin stripping liquid exceeds the preset value of the tin stripping machine, the condensation component 25 cools the tin stripping liquid in time to reduce the temperature of the tin stripping liquid and avoid excessive corrosion of the product 6.

[0038] In this embodiment, the tin stripping device 2 also includes an emptying unit (not shown in the accompanying drawings). When the tin stripping time monitoring sensor 23 detects that the product 6 has not been moved out of the tin stripping device 2 at the set time point, the emptying unit triggers the alarm device, the tin stripping machine stops, and the tin stripping liquid is discharged from the tin stripping upper tank 211 at the same time, so that the liquid level of the tin stripping liquid drops to a level that does not contact the product 6, thereby protecting the product 6 from excessive corrosion.

[0039] In this embodiment, the cleaning tank 31 includes an upper cleaning tank 311 and a lower cleaning tank 312, and the upper cleaning tank 311 and the lower cleaning tank 312 are connected by an inlet pipe 321 and an outlet pipe 322. The cleaning liquid can circulate between the upper cleaning tank 311 and the lower cleaning tank 312 through the inlet pipe 321 and the outlet pipe 322, and the product after the tin stripping treatment can be placed in the upper cleaning tank 311 for cleaning. The cleaning liquid contained in the cleaning tank 31 can complete the circulation between the upper cleaning tank 311 and the lower cleaning tank 312 through the inlet pipe 321 and the outlet pipe 322, ensuring that the cleaning liquid in the cleaning tank 31 is always in an overflow state, so as to fully clean the product 6. The cleaning liquid can be deionized water.

[0040] In this embodiment, the cleaning device 3 further includes a bubbling device 34, which is disposed in the lower cleaning tank 312 and is used to inject gas into the cleaning liquid of the cleaning device 3 to improve the cleaning efficiency. The cleaning liquid in the cleaning tank 31 of the cleaning device 3 is always in a circulating flow state, and the bubbling device 34 is provided to ensure that the tin stripping liquid residue on the surface of the product 6 is thoroughly cleaned.

[0041] In this embodiment, the cleaning device 3 further includes a cleaning time monitoring sensor 33. The cleaning time monitoring sensor 33 includes a third probe 331 and a fourth probe 332 on the product conveying path, and uses the time difference between the product 6 passing through the two probes to monitor the cleaning time of the product 6. By monitoring the cleaning time of the product 6, it can be ensured that the product 6 is thoroughly cleaned, thereby avoiding the tin stripping liquid residue on the surface of the product 6.

[0042] In this embodiment, the drying device 4 includes an upper drying tank 411, a lower drying tank 412, and an air generator 43. The upper drying tank 411 and the lower drying tank 412 are connected by an air inlet pipe 42. The air generator 43 is placed in the lower drying tank 412. The hot air generated by the air generator 43 can enter the upper drying tank 411 through the air inlet pipe 42 to dry the product 6. After the cleaning, the product 6 is transported to the upper drying tank 411 of the drying device 4 by the conveying device 1. The air generator 43 provides hot air of 100-130°C from the lower drying tank 412 to the upper drying tank 411 through the air inlet pipe 42 to dry the product 6. The drying device 4 can reduce the transportation process of the product 6, thereby saving the circulation time of the product 6 and improving efficiency.

[0043] In this embodiment, the inspection device 5 can inspect whether the product 6 has abnormal tin stripping problems through a CCD automatic detection device, thereby improving inspection efficiency.

[0044] In this embodiment, the desoldering machine also includes a control system, which controls the time and temperature of the desoldering device 2, the cleaning device 3, the drying device 4 and the inspection device 5. When the desoldering process of the product 6 is abnormal, the control system controls the alarm device to sound an alarm and stop the ongoing process of the desoldering machine.

[0045] The above technical solution is provided with a conveying device, a tin stripping device, a cleaning device, a drying device, and a detection device. After the product is transmitted from the tin stripping device by the conveying device, it is sequentially transmitted to the cleaning device and the drying device, and then transmitted to the detection device for detection to determine whether the tin layer on the surface of the product has been completely stripped. The tin stripping machine can ensure the quality of the product while automating the tin stripping process. In the utility model, the tin stripping device also includes a process parameter monitoring unit for monitoring the process parameters of the tin stripping process, which can avoid insufficient or excessive tin stripping and improve the reliability of the product.
