Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, and in particular to a PCB lifting multi-tank immersion device. Background Technology

[0002] In PCB manufacturing, multi-tank immersion equipment with a PCB lifting mechanism is commonly used to immerse PCBs in various chemicals. Current technology often employs static immersion for this process. This static immersion method can easily lead to insufficient contact between the PCB's holes and the chemicals, thus reducing PCB quality. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a PCB lifting multi-tank immersion device, which enables the holes on the PCB to fully contact the solution, thereby helping to ensure the quality of the PCB.

[0004] A PCB lifting multi-tank immersion device according to an embodiment of the present invention includes a frame, a basket, a lifting and moving device, a swinging device, and multiple immersion chambers. Each of the multiple immersion chambers is used to hold a solution, and the multiple immersion chambers are evenly distributed on the frame from back to front. The basket is used to hold the PCB. The lifting and moving device is mounted on the frame and is used to drive the basket to move in the front-back direction and the up-down direction, so that the basket can be sequentially immersed in the solution in the multiple immersion chambers from back to front, and the PCB in the basket can be sequentially immersed in the solution in the multiple immersion chambers. The swinging device is used to drive the basket to swing back and forth, so that the holes on the PCB in the basket can fully contact the solution.

[0005] It has at least the following beneficial effects:

[0006] When PCBs need to be soaked, operators place the PCBs to be soaked into a basket. A lifting and moving device then moves the basket vertically and horizontally, allowing it to be sequentially immersed in the chemicals in multiple soaking chambers. This process completes multiple soaking steps for the PCBs. During immersion, a swinging device causes the basket and the PCBs within it to swing back and forth. This swinging motion moves the basket and the surrounding chemicals, creating a localized water flow. This flow continuously washes the surface and holes of the PCB. Compared to static soaking, this increases the relative speed between the chemicals and the PCB, allowing the chemicals to penetrate the holes more quickly. It also removes diluted or reacted chemicals from the holes, constantly replenishing them with fresh chemicals. This ensures thorough contact between the chemicals and the PCB, thus guaranteeing PCB quality.

[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model discloses a PCB lifting type multi-tank soaking equipment, including a frame 400, a basket 300, a lifting and moving device 200, a swinging device 100, and multiple soaking chambers 410.

[0033] Multiple soaking chambers 410 are used to hold chemicals, and the multiple soaking chambers 410 are evenly distributed on the frame 400 from back to front. A basket 300 is used to hold PCBs. A lifting and moving device 200 is provided on the frame 400, and the lifting and moving device 200 is used to drive the basket 300 to move in the front-back direction and the up-down direction, so that the basket 300 can be sequentially immersed in the chemicals in the multiple soaking chambers 410 from back to front, and so that the PCBs in the basket 300 can be sequentially immersed in the chemicals in the multiple soaking chambers 410. A swinging device 100 is used to drive the basket 300 to swing back and forth, so that the holes on the PCBs in the basket 300 can fully contact the chemicals.

[0034] It's important to clarify that PCB (Printed Circuit Board) is a type of PCB. Currently, static immersion is commonly used to soak PCBs. This method results in slow chemical flow, making it difficult for the chemicals to quickly and fully penetrate the PCB's holes, especially deep or small holes. This leads to insufficient contact between the holes and the chemicals. If the holes don't fully contact the chemicals during the electroplating stage, the copper plating thickness on the hole walls will be insufficient or uneven, easily causing poor conductivity and affecting the stability of signal transmission, thus reducing the overall quality of the PCB.

[0035] Multiple soaking chambers 410 are evenly distributed from back to front on the frame 400, each containing chemicals for different processes. A lifting and moving device 200 is mounted on the frame 400, and its output end is connected to a basket 300. The lifting and moving device 200 can drive the basket 300 to move in the front-back and up-down directions, allowing it to move sequentially into multiple soaking chambers 410. Specifically, the lifting and moving device 200 first drives the basket 300 to descend, immersing it in the chemicals in the last soaking chamber 410. After the PCB has reached the specified soaking time, the lifting and moving device 200 drives the basket 300 to rise and move it forward, placing it above the next soaking chamber 410. Next, the lifting and moving device 200 lowers the basket 300, immersing it in the solution in the next soaking chamber 410. This process is repeated, allowing the basket 300 to be sequentially immersed in the solution in multiple soaking chambers 410 from back to front, ensuring that the PCBs inside the basket 300 are sequentially immersed in the solution. Further details are omitted here. The basket 300 is a box structure composed of multiple grid panels, capable of holding multiple PCBs. The solution can flow into or out of the basket 300, ensuring sufficient contact between the solution and the PCBs inside.

[0036] In this embodiment of the invention, the multiple immersion chambers 410 represent multiple immersion positions. As one embodiment of the invention, the PCB lifting-type multi-tank immersion device includes five immersion chambers 410, which can be used for PCB immersion gold plating. The five immersion chambers 410, from back to front, correspond to water washing, acid immersion, electroless nickel plating, electroless gold plating, and water washing processes, respectively. The solutions in the five immersion chambers 410 are all common solutions used in PCB immersion gold plating processes, and will not be further described here. The PCB lifting-type multi-tank immersion device can also be used for other PCB immersion processes, which will not be further described here.

[0037] Understandably, when PCB immersion treatment is required, the operator can place the PCB to be immersed in the basket 300. Then, the lifting and moving device 200 can drive the basket 300 to move vertically and horizontally, allowing it to be sequentially immersed in the chemical solution within multiple immersion chambers 410. This ensures the PCB in the basket 300 is sequentially immersed in the chemical solution within the multiple immersion chambers 410, completing the multiple immersion process for the PCB. During the PCB immersion process, the swinging device 100 can drive the basket 300 and the PCB within it to swing back and forth. During the swinging of the basket 300, the basket 300 and the PCB within it will move the surrounding chemical solution, creating a localized water flow. The water flow generated by the chemical solution can continuously wash the surface and holes of the PCB. Compared with static soaking, it increases the relative speed of the chemical solution and the PCB, allowing the chemical solution to enter the holes of the PCB more quickly. At the same time, it can also promptly remove the diluted or reacted chemical solution from the PCB holes, allowing fresh chemical solution to be continuously replenished. This achieves full contact between the holes of the PCB and the chemical solution, thus helping to ensure the quality of the PCB.

[0038] On the other hand, the swinging motion of the PCB caused by the 300 basket makes it easier to expel air from the holes on the PCB. Once the air is expelled, the solution can more smoothly fill the internal space of the holes, thereby increasing the contact area between the solution and the hole wall. This ensures sufficient contact between the solution and the holes on the PCB, which in turn helps to guarantee the quality of the PCB.

[0039] refer to Figure 3 and Figure 4The swing device 100 includes a base 110 and a rotary drive assembly 120. The base 110 is connected to the output end of the lifting and moving device 200. The rotary drive assembly 120 is disposed on the base 110, and the suspended basket 300 is rotatably connected to the base 110. The rotary drive assembly 120 is used to drive the suspended basket 300 to swing. The rotary drive assembly 120 includes a first rotary drive member 121, a drive sprocket 122, a driven sprocket 123, and a chain 124. The first rotary drive member 121 is disposed on the base 110. The drive sprocket 122 is connected to the output end of the first rotary drive member 121. The driven sprocket 123 is connected to the suspended basket 300. The chain 124 is wound around the drive sprocket 122 and the driven sprocket 123. The first rotary drive member 121 is used to drive the drive sprocket 122 to rotate. It is understood that during the process of immersing the basket 300 and the PCB in the solution within the immersion chamber 410, the first rotary drive 121 can drive the drive sprocket 122 to reciprocate, causing the drive sprocket 122 to drive the chain 124 and the driven sprocket 123 to reciprocate. Since the basket 300 is rotatably connected to the base 110 and is connected to the driven sprocket 123, the driven sprocket 123 can drive the basket 300 to swing back and forth. It should be explained that in this utility model, reciprocating rotation refers to rotation alternately in two directions. In this embodiment of the utility model, the first rotary drive 121 can be a first motor. It should be explained that during the PCB immersion process, the basket 300, the driven sprocket 123, the lower part of the base 110, and the lower part of the chain 124 are all simultaneously immersed in the solution, while the drive sprocket 122 and the first rotary drive 121 are both located above the solution.

[0040] refer to Figures 4 to 6The lifting and moving device 200 includes a slide table 240, a first lifting component 210, a second lifting component 220, and a moving drive component 230. The slide table 240 is slidably connected to the frame 400 in the front-back direction and is located above multiple soaking chambers 410. The first lifting component 210 and the second lifting component 220 are both located on the slide table 240. The output ends of the first lifting component 210 and the second lifting component 220 are respectively connected to the left and right sides of the basket 300. The first lifting component 210 and the second lifting component 220 are used to simultaneously drive the basket 300 to rise and fall. The moving drive component 230 is located on the frame 400 and is used to drive the slide table 240 to move in the front-back direction. Understandably, the output ends of the first lifting component 210 and the second lifting component 220 on the slide table 240 are both connected to the suspended platform 300. When the suspended platform 300 needs to be raised or lowered, the first lifting component 210 and the second lifting component 220 are activated simultaneously, enabling them to simultaneously drive the suspended platform 300 to rise or fall. When the suspended platform 300 needs to be moved forward or backward, the movement drive component 230 drives the slide table 240 and the first lifting component 210 and the second lifting component 220 on the slide table 240 to move in the forward or backward direction, thereby enabling the suspended platform 300 connected to the output ends of the first lifting component 210 and the second lifting component 220 to move in the forward or backward direction.

[0041] refer to Figure 5 and Figure 6 The moving drive assembly 230 includes a second rotary drive component 231, two first driving pulleys 232, two first driven pulleys 233, and two first belts 234. The second rotary drive component 231 is mounted on the frame 400. The two first driving pulleys 232 are rotatably connected to the frame 400 and are respectively located on the left and right sides of the frame 400. The two first driven pulleys 233 are rotatably connected to the frame 400 and are respectively located on the left and right sides of the frame 400. On both sides, two first driven pulleys 233 are located in front of two first driving pulleys 232. Two first belts 234 are respectively wound around the first driving pulley 232 and the first driven pulley 233 located on the same side. The two first belts 234 are parallel to the front-back direction. The left and right sides of the slide table 240 are respectively connected to the two first belts 234. The second rotary drive member 231 is used to drive the two first driving pulleys 232 to rotate synchronously, so that the two first belts 234 synchronously drive the slide table 240 to move in the front-back direction.

[0042] It is understood that the two first driven pulleys 233 are located directly in front of the two first driving pulleys 232, and the two first belts 234 are respectively wound around the first driving pulley 232 and the first driven pulley 233 on the same side, where "the same side" refers to the left or right side. Both first belts 234 are parallel to the front-back direction. When the basket 300 needs to be moved forward or backward, the second rotary drive 231 drives the two first driving pulleys 232 to rotate synchronously, so that the two first driving pulleys 232 can drive the two first belts 234 to rotate synchronously. Since the two first belts 234 are connected to the left and right sides of the slide 240 respectively, the two first belts 234 can synchronously drive the slide 240 to move along the front-back direction on the frame 400. It should be explained that the direction of movement of the slide 240 depends on the direction of rotation of the two first driving pulleys 232 driven by the second rotary drive 231, which will not be further elaborated here. In this embodiment of the present invention, the second rotary drive 231 can be a second motor. refer to Figure 1 and Figure 2 The upper end of the frame 400 has a slide groove 420 parallel to the front-back direction. A slider 241 is provided on the slide table 240, and the slider 241 is slidably connected to the slide groove 420 in the front-back direction. In this embodiment of the invention, the upper end of the frame 400 has two slide grooves 420 parallel to the front-back direction. Slider 241s are provided on both the left and right sides of the slide table 240. The two sliders 241 are slidably connected to the two slide grooves 420 in the front-back direction, and are respectively connected to two first belts 234.

[0043] refer to Figure 5The mobile drive assembly 230 also includes a drive shaft 235, a second drive pulley 236, a second driven pulley 237, and a second belt 238. The left and right ends of the drive shaft 235 are respectively connected to two first drive pulleys 232. The second drive pulley 236 is connected to the output end of the second rotary drive member 231. The second driven pulley 237 is mounted on the drive shaft 235. The second belt 238 is wound around the second drive pulley 236 and the second driven pulley 237. The second rotary drive member 231 drives the second drive pulley 236 to rotate, so that the drive shaft 235 drives the two first drive pulleys 232 to rotate synchronously. It can be understood that the drive shaft 235 is parallel to the left-right direction, the two first drive pulleys 232 are connected by the drive shaft 235, and the second driven pulley 237 is located in the middle of the drive shaft 235. The second rotary drive component 231 drives the second drive pulley 236 to rotate, causing the second drive pulley 236 to drive the second belt 238 and the second driven pulley 237 to rotate, which in turn causes the second driven pulley 237 to drive the drive shaft 235 to rotate. Since the left and right ends of the drive shaft 235 are respectively connected to the two first drive pulleys 232, the drive shaft 235 rotating around its own axis can simultaneously drive the two first drive pulleys 232 to rotate, thus enabling the two first drive pulleys 232 to rotate synchronously. In this embodiment of the present invention, the mobile drive assembly 230 includes two drive shafts 235, and the two first driven pulleys 233 are also connected by drive shafts 235, so that the two first driven pulleys 233 can also rotate synchronously.

[0044] refer to Figure 6The first lifting assembly 210 includes a third rotary drive 211, a connecting shaft 212, two winches 213, and two cables 214. The third rotary drive 211 is mounted on a slide table 240. Both winches 213 are rotatably connected to the slide table 240. The connecting shaft 212 is parallel to the front-rear direction, and the two winches 213 are connected to each other via the connecting shaft 212. One end of each cable 214 is connected to one of the two winches 213, and the other end of each cable 214 is connected to the suspended platform 300. The third rotary drive 211 drives the connecting shaft 212 to rotate, so that the two winches 213 can unwind or wind the two cables 214 respectively. It can be understood that the other ends of the two cables 214 are connected to the front and rear ends of the right side of the suspended platform 300, respectively, and the two winches 213 are used for winding the two cables 214. When the suspended platform 300 needs to be raised, the third rotary drive 211 drives the connecting shaft 212 to rotate clockwise around its own axis, causing the connecting shaft 212 to simultaneously drive the two winches 213 to rotate. Under the action of the two winches 213, the two cables 214 are wound around the two winches 213 respectively, causing the two winches 213 to wind up the two cables 214 respectively. At this time, the two cables 214 exert an upward pulling force on the suspended platform 300, thus raising the suspended platform 300. When the suspended platform 300 needs to be lowered, the third rotary drive 211 drives the connecting shaft 212 to rotate counterclockwise around its own axis, causing the connecting shaft 212 to simultaneously drive the two winches 213 to rotate. Under the action of the two winches 213, the two cables 214 are released from the two winches 213 respectively, causing the two winches 213 to unwind the two cables 214 respectively, thus lowering the suspended platform 300. In this embodiment of the present invention, the third rotary drive 211 can be a third motor.

[0045] refer to Figure 6 The first lifting assembly 210 also includes two support wheels 215, both of which are rotatably connected to the slide table 240. Two cables 214 are respectively wound around the two support wheels 215. A limiting groove is formed on the outer wall of each support wheel 215 for the cables 214 to extend into. It is understood that the two cables 214 are respectively wound around the two support wheels 215 so that the support wheels 215 can support the two cables 214, ensuring that the cables 214 can move stably. The limiting groove on the outer wall of the support wheel 215 allows the cables 214 to extend into the limiting groove and abut against the inner bottom wall of the limiting groove. The inner side wall of the limiting groove can limit the movement of the cables 214, preventing them from swaying during movement and ensuring that the suspended platform 300 can rise and fall smoothly. In this embodiment of the present invention, reference is made to… Figure 5The second lifting component 220 has the same structure as the first lifting component 210, and the two lifting components 220 and the first lifting component 210 are symmetrical in the left-right direction. The other ends of the two cables 214 in the second lifting component 220 are respectively connected to the front and rear ends of the left side of the suspended platform 300, which will not be further described here. Specifically, in this embodiment of the present invention, the two cables 214 in the first lifting component 210 are respectively connected to the front and rear ends of the right side of the base 110, and the two cables 214 in the second lifting component 220 are respectively connected to the front and rear ends of the left side of the base 110. In this embodiment of the present invention, the output end of the lifting moving device 200 is connected to the swing device 100, and the output end of the swing device 100 is connected to the suspended platform 300. In this embodiment of the present invention, the slide table 240 has two clearance holes, one clearance hole for the two cables 214 in the first lifting component 210 to pass through, and the other clearance hole for the two cables 214 in the second lifting component 220 to pass through.
