[0002] In the fields of electronics industry such as semiconductor manufacturing and circuit board production, etching technology is a crucial processing technology, which is widely used in the manufacture of microcircuit structures. With the miniaturization and high integration of electronic products, the requirements for etching accuracy and efficiency are also increasing day by day.

[0003] In recent years, the development of etching technology has experienced a transformation from traditional manual operation to semi-automation and then to full automation. However, there are still some deficiencies in the existing processing and assembly devices for etching machine chuck boards: First, during the etching process, the etching solution is prone to stratification due to long-term static placement, resulting in inconsistent etching effects and affecting product quality. Currently, the common method to solve this problem is to manually stir the etching solution regularly during the etching process, but this not only increases the operation complexity but also makes it difficult to ensure the uniformity and timeliness of stirring.

Detailed implementation manners

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: As Figures 1 - 3 and Figure 10 shown, a processing and assembling device for an etching machine card includes a box body 100, a plurality of water tanks 105, two groups of flushing mechanisms 110, a card clamping mechanism 200, and a driving mechanism 300.

[0022] The top of the box body 100 is open, and a partition is installed inside the box body 100. The partition divides the internal space of the box body 100 into an etching tank 101 and a flushing tank 102. The etching tank 101 is used to contain etching liquid, and two racks 104 are installed in the etching tank 101; a drain pipe is installed on the box body 100, and the drain pipe is communicated with the flushing tank 102. Two guiding grooves 103 are provided on the inner wall of the box body 100.

[0023] A plurality of water tanks 105 are all installed on the bottom surface of the box body 100; the plurality of water tanks 105 are connected by a connecting pipe 106, so that the plurality of water tanks 105 communicate with each other.

[0024] A bracket 107 is also installed on the box body 100, and the bracket 107 is used to place the circuit board. Two sets of flushing mechanisms 110 are both installed on the box body 100; the clamping plate clamping mechanism 200 includes a clamping component 210 and a liquid mixing component 220, and the clamping component 210 is used to clamp and fix the circuit board. The driving mechanism 300 is used to drive the clamping plate clamping mechanism 200 to move.

[0025] Specifically, etching liquid is added into the etching tank 101, and clean water is added into the water tank 105. Then, the circuit board to be etched is clamped and fixed by the clamping plate clamping mechanism 200.

[0026] Then, the driving mechanism 300 is started to drive the clamping plate clamping mechanism 200 to move. When the clamping plate clamping mechanism 200 moves in the etching tank 101, the etching liquid contacts the circuit board and etches the circuit board; and when the clamping plate clamping mechanism 200 moves in the etching tank 101, the liquid mixing component 220 will stir the etching liquid in the etching tank 101 under the influence of the rack 104, so as to avoid the layering and segregation of the etching liquid and improve the etching effect.

[0027] When the clamping plate clamping mechanism 200 moves in the flushing tank 102, the liquid mixing component 220 will drive the two sets of flushing mechanisms 110 to operate, so that the flushing mechanisms 110 pump out the water in the water tank 105 and spray it on the circuit board to flush the circuit board after etching is completed.

[0028] As Figure 3 and Figure 10 shown, the clamping plate clamping mechanism 200 further includes a mounting seat 201 and two first telescopic rods 202, and the two first telescopic rods 202 are both installed on the bottom surface of the mounting seat 201.

[0029] Specifically, by setting the first telescopic rod 202, when the clamping plate clamping mechanism 200 moves along the guide groove 103, the setting of the first telescopic rod 202 allows the clamping component 210 and the liquid mixing component 220 to move up and down.

[0030] As Figure 3 and Figure 4 shown, the clamping component 210 includes a bearing plate 211, two moving plates 212, a plurality of second telescopic rods 216, two clamping plates 217, a plurality of second springs 218 and an adjusting component.

[0031] The bearing plate 211 is installed on the extension ends of two first telescopic rods 202; two moving plates 212 are respectively slidably connected to the two bearing plates 211; a plurality of second telescopic rods 216 are respectively installed on the opposite sides of the two moving plates 212; two clamping plates 217 are respectively connected to the extension ends of the plurality of second telescopic rods 216, and the two clamping plates 217 are used for clamping and fixing the circuit board; a plurality of second springs 218 are respectively sleeved on the plurality of second telescopic rods 216; the adjusting member is used for adjusting the distance between the two moving plates 212.

[0032] Specifically, the adjusting member drives the two moving plates 212 to move, and then drives the two clamping plates 217 to move, so that the two clamping plates 217 can clamp and fix circuit boards of different sizes. The clamping assembly 210 realizes the clamping and buffering of the circuit board through the bearing plate 211, the moving plate 212, the second telescopic rod 216, the clamping plate 217 and the second spring 218, ensuring the stability and safety of clamping.

[0033] As Figure 3 and Figure 5 As shown in, the liquid mixing assembly 220 includes two vertical plates 221, two cylinders 222, two spiral stirring rods 223, two spiral stirring rods 223, a cross bar 224, two first bevel gears 225, two second bevel gears 226 and two gears 227.

[0034] Both of the two vertical plates 221 are fixedly connected to the mounting base 201; the two cylinders 222 are respectively installed on the two vertical plates 221, and the top and bottom of the cylinder 222 are both open. The two spiral stirring rods 223 are respectively rotatably installed in the two cylinders 222; the cross bar 224 is rotatably connected to the two vertical plates 221, and the two ends of the cross bar 224 are respectively slidably connected to the guide grooves 103 formed on the inner wall of the box body 100; the two first bevel gears 225 are both fixedly sleeved on the cross bar 224; the two second bevel gears 226 are respectively installed at the lower ends of the two spiral stirring rods 223, and the two second bevel gears 226 are respectively meshed with the two first bevel gears 225; the two gears 227 are both fixedly sleeved on the cross bar 224, and the two gears 227 are matched with the two racks 104.

[0035] Specifically, when the gear 227 rotates, it will drive the cross bar 224 to rotate, and then drive the spiral stirring rod 223 to rotate through the first bevel gear 225 and the second bevel gear 226. The rotating spiral stirring rod 223 will convey the etching solution at the lower part of the cylinder 222 upward, so as to agitate the etching solution, avoid the layering and segregation of the etching solution, and improve the etching efficiency.

[0036] As Figure 1 , Figure 6 and Figure 7As shown, the flushing mechanism 110 includes a piston cylinder 111, a semi-circular toothed plate 113, a first spring 114, a hollow plate 117, and a plurality of spray nozzles 118.

[0037] The piston cylinder 111 is installed on the box body 100. A piston piece is slidably connected inside the piston cylinder 111. A piston rod 112 slidably connected to the piston cylinder 111 is installed on the piston piece. A water suction pipe 115 and a water delivery pipe 116 are installed at the bottom of the piston cylinder 111. The other end of the water suction pipe 115 is connected to the water tank 105.

[0038] The semi-circular toothed plate 113 is installed at the upper end of the piston rod 112, and the semi-circular toothed plate 113 is matched with the gear 227; the first spring 114 is sleeved on the piston rod 112; both ends of the first spring 114 are fixedly connected to the semi-circular toothed plate 113 and the piston cylinder 111 respectively.

[0039] The hollow plate 117 is installed on the box body 100, and the hollow plate 117 is connected to the water delivery pipe 116; a plurality of spray nozzles 118 are all installed on the hollow plate 117, and a plurality of spray nozzles 118 all extend into the box body 100.

[0040] One-way valves are installed in both the water suction pipe 115 and the water delivery pipe 116, so that the water in the water tank 105 can only enter the piston cylinder 111 unidirectionally through the water suction pipe 115, and the water in the piston cylinder 111 can only enter the hollow plate 117 unidirectionally through the water delivery pipe 116.

[0041] Specifically, when the semi-circular toothed plate 113 moves downward, it will drive the piston rod 112 and the piston piece to move, and then deliver the water in the piston cylinder 111 to the hollow plate 117 through the liquid delivery pipe; When the semi-circular toothed plate 113 moves upward, it will drive the piston rod 112 and the piston piece to move upward, and then the piston cylinder 111 will draw the water in the water tank 105 through the water suction pipe 115.

[0042] By setting the first spring 114, the semi-circular toothed plate 113 can be automatically reset. By repeatedly pressing and releasing the semi-circular toothed plate 113, with the cooperation of the first spring 114, the piston cylinder 111 will continuously draw the water in the water tank 105 and continuously deliver the water to the hollow plate 117, so that the air in the hollow plate 117 is sprayed out through a plurality of spray nozzles 118.

[0043] As Figure 4 shown, the adjusting component includes two first lead screw nuts 213, a first lead screw 214, a first motor 215, a third spring 2171, a pressing plate 2172, a pressure sensor 2121, and a controller 219.

[0044] Two first lead screw nuts 213 are respectively installed through two moving plates 212; a first lead screw 214 is installed through two first lead screw nuts 213, and the thread patterns at both ends of the first lead screw 214 are arranged in the opposite direction; a first motor 215 is installed on the bottom surface of the bearing plate 211, and the power output shaft of the first motor 215 is fixedly connected to the first lead screw 214; a third spring 2171 is installed on the clamping plate 217; a pressing plate 2172 is fixedly connected to the third spring 2171; a pressure sensor 2121 is installed on the moving plate 212, and the pressure sensor 2121 faces the pressing plate 2172; a controller 219 is installed on the bearing plate 211, and the controller 219 is used to shut down the operation of the first motor 215.

[0045] The controller 219 is used to receive the pressure data sent by the pressure sensor 2121, and compare the pressure data with a preset pressure threshold. When the pressure data is greater than or equal to the preset pressure threshold, the controller 219 will control to shut down the operation of the first motor 215.

[0046] Specifically, a pressure threshold is preset on the controller 219. Then, by placing the circuit board on the bracket 107, at this time the circuit board is located between two clamping plates 217. By starting the first motor 215, the first lead screw 214 is driven to rotate, and then the two first lead screw nuts 213 are driven to move simultaneously in the opposite directions, thereby adjusting the distance between the two moving plates 212, and further adjusting the distance between the two clamping plates 217, so that the two clamping plates 217 clamp the circuit board.

[0047] At this time, the clamping plate 217 will also move in the direction close to the moving plate 212, and then drive the pressing plate 2172 to move in the direction close to the pressure sensor 2121, so that the pressing plate 2172 presses the pressure sensor 2121. The controller 219 receives the pressure data received by the pressure sensor 2121, and compares the pressure data with the preset pressure threshold. When the pressure data is equal to the preset pressure threshold, the controller 219 will control to shut down the operation of the first motor 215, thereby preventing the circuit board from being damaged.

[0048] It should be noted that the relationship between the extrusion force received by the circuit board and the pressure received by the pressure sensor 2121 can be obtained by those skilled in the art according to the actual situation and a large amount of data simulation.

[0049] As Figure 8 shown, the driving mechanism 300 includes a first frame body 301, a second frame body 302, a second motor 303, a second lead screw 304 and a second lead screw nut 305.

[0050] The first frame body 301 is installed on one side of the box body 100; the second frame body 302 is installed on the other side of the box body 100; the second motor 303 is installed on the second frame body 302; the second lead screw 304 is installed on the power output shaft of the second motor 303, and the second lead screw 304 is rotationally connected to the first frame body 301 and the second frame body 302; the second lead screw nut 305 is sleeved on the second lead screw 304, and the second lead screw nut 305 is fixedly connected to the mounting seat 201.

[0051] Specifically, when the second motor 303 operates, it will drive the second lead screw 304 to rotate, thereby causing the second lead screw nut 305 to move horizontally, further driving the mounting seat 201 to move horizontally, and further driving the entire clamping mechanism 200 of the chuck to move.

[0052] As Figure 1 shown, when the cross bar 224 moves along the guide groove 103, the gear 227 will mesh with the rack 104 and the semi-circular toothed plate 113. When the gear 227 meshes with the rack 104, it will drive the liquid mixing assembly 220 to operate; when the gear 227 meshes with the semi-circular toothed plate 113, it will push the semi-circular toothed plate 113 to move downward, thereby driving the flushing mechanism 110 to spray water, improving the automation degree of the equipment.

[0053] As Figure 1 、 Figure 2 and Figure 9 shown, the processing and assembly equipment for the etching machine chuck further includes a blowing mechanism 400, and the blowing mechanism 400 includes a fixed cylinder 401, a duct 402, an air outlet groove 403, a fixed bracket 404, a third motor 405 and blades 406.

[0054] The fixed cylinder 401 is installed on the second frame body 302; the duct 402 is installed on the fixed cylinder 401; the air outlet groove 403 is opened on the duct 402; the fixed bracket 404 is installed in the fixed cylinder 401; the third motor 405 is installed on the fixed bracket 404; the blades 406 are installed on the power output shaft of the third motor 405.

[0055] Specifically, when the third motor 405 operates, it will drive the blades 406 to rotate, thereby delivering air into the duct 402. The air in the duct 402 will be blown out through the air outlet groove 403, and the air blown out from the air outlet groove 403 will blow onto the circuit board, realizing rapid drying of the circuit board and improving the production efficiency.

[0056] Working principle: During specific use, by placing the circuit board to be etched on the bracket 107, at this time the circuit board is located between the two clamping plates 217; Then, start the first motor 215 to drive the first lead screw 214 to rotate, thereby driving the two first lead screw nuts 213 to move simultaneously in opposite directions, thereby adjusting the distance between the two moving plates 212, and further adjusting the distance between the two clamping plates 217, so that the two clamping plates 217 clamp the circuit board, and then turn off the first motor 215.

[0057] Then, start the second motor 303. When the second motor 303 runs, it will drive the second lead screw 304 to rotate, thereby causing the second lead screw nut 305 to move horizontally, thereby driving the mounting seat 201 to move horizontally, and further driving the entire card clamping mechanism 200 to move along the two guide grooves 103.

[0058] When the card clamping mechanism 200 moves in the etching tank 101, the etching solution contacts the circuit board and etches the circuit board; and when the card clamping mechanism 200 moves in the etching tank 101, the gear 227 in the mixing component 220 will engage with the rack 104. Under the influence of the rack 104, the gear 227 will rotate, thereby driving the cross bar 224 to rotate, and further driving the spiral stirring rod 223 to rotate through the first bevel gear 225 and the second bevel gear 226. The rotating spiral stirring rod 223 will transport the etching solution at the lower part of the cylinder body 222 upward, thereby turning over the etching solution, avoiding the stratification and segregation of the etching solution, and improving the etching efficiency.

[0059] As the second motor 303 continues to run, the card clamping mechanism 200 and the circuit board will enter the flushing tank 102. When the card clamping mechanism 200 moves in the flushing tank 102, the gear 227 will contact the semi-circular toothed plate 113 and push the semi-circular toothed plate 113 downward, thereby driving the piston rod 112 and the piston piece to move downward, and further squeezing the water in the piston cylinder 111 into the hollow plate 117. The water in the hollow plate 117 will be sprayed out through multiple nozzles 118, and the sprayed water will fall on the circuit board, thereby flushing the circuit board.

[0060] Then, start the second motor 303 to drive the second lead screw 304 to rotate counterclockwise, thereby driving the card clamping mechanism 200 to move towards the direction close to the first frame body 301, so that the card clamping mechanism 200 is located between the first frame body 301 and the semi-circular toothed plate 113. Then control the second motor 303 to drive the second lead screw 304 to rotate clockwise, so that the gear 227 will contact the semi-circular toothed plate 113 and push the semi-circular toothed plate 113 downward, so that the water sprayed by the nozzles 118 flushes the circuit board. Repeat the above operation to continuously flush the circuit board with the nozzles 118, so as to flush the residual etching solution on the circuit board clean.

[0061] Then, control the second motor 303 to drive the second lead screw 304 to rotate clockwise, so that the clamping plate clamping mechanism 200 is moved out of the flushing tank 102. Then, turn off the second motor 303 and start the third motor 405. When the third motor 405 operates, it will drive the blade 406 to rotate, thereby delivering air into the air duct 402. The air in the air duct 402 will be blown out through the air outlet groove 403, and the air blown out from the air outlet groove 403 will blow onto the circuit board, realizing the rapid drying of the circuit board and improving the production efficiency.

[0062] After the circuit board is dried, start the first motor 215 to drive the first lead screw 214 to move by the first motor 215, and then drive the two first lead screw nuts 213 to move in opposite directions at the same time, and then drive the two moving plates 212 and the clamping plates 217 to move in opposite directions, so as to facilitate the removal of the circuit board.

[0063] After completing the above operations, start the second motor 303 to drive the power output shaft of the second motor 303 to drive the second lead screw 304 to rotate counterclockwise, so that the clamping plate clamping mechanism 200 moves towards the direction close to the first frame 301, and reset the clamping plate clamping mechanism 200 to etch the subsequent circuit boards.

[0064] Embodiment 2: As Figures 1 - 10 shown, a method for using an etching machine clamping plate processing and assembling device includes the following steps: Step 1: Add an appropriate amount of etching solution into the etching tank 101 to ensure that the liquid level reaches the specified height; add clean water into the water tank 105 for flushing the circuit board. Step 2: Place the circuit board to be etched on the bracket 107 to ensure the correct position of the circuit board. Start the first motor 215 to drive the first lead screw 214 to rotate, and then drive the two first lead screw 214 nuts 213 to move in opposite directions at the same time, and then adjust the distance between the two moving plates 212, and then drive the two clamping plates 217 to move until the clamping plates 217 firmly clamp the circuit board. Step 3: Start the second motor 303 to drive the second lead screw 304 to rotate, and then the second lead screw 304 nut moves horizontally, and then drives the entire clamping plate clamping mechanism 200 to move along the guide groove 103; when the clamping plate clamping mechanism 200 enters the etching tank 101, the etching solution will contact the circuit board, and the etching solution will etch the circuit board; at the same time, the gear 227 in the liquid mixing assembly 220 meshes with the rack 104 to drive the spiral stirring rod 223 to rotate, and the rotating spiral stirring rod 223 conveys the etching solution at the lower part of the etching tank 101 upwards, and then stirs the etching solution to avoid stratification and segregation of the etching solution and improve the etching effect. Step 4: As the driving mechanism 300 continues to operate, the clamping mechanism 200 drives the circuit board into the flushing tank 102. Inside the flushing tank 102, the gear 227 in the liquid mixing assembly 220 contacts the semi-circular toothed plate 113 of the flushing mechanism 110 and pushes the semi-circular toothed plate 113 downward. The movement of the semi-circular toothed plate 113 drives the piston rod 112 and the piston piece downward, delivering the water in the piston cylinder 111 to the hollow plate 117 through the water delivery pipe 116 and then spraying it out through multiple nozzles 118 to flush the circuit board. Step 5: Control the driving mechanism 300 to repeatedly move the clamping mechanism 200 as needed to achieve multiple flushes and ensure that the residual etching solution on the surface of the circuit board is completely flushed away. Step 6: After the clamping mechanism 200 is removed from the flushing tank 102, turn off the second motor 303, then start the third motor 405 to drive the blade 406 to rotate, delivering air into the air guide pipe 402. The air in the air guide pipe 402 is blown out through the air outlet groove 403 and blown onto the circuit board to achieve rapid drying. After drying, take out the circuit board from between the two clamping plates 217. Step 7: Start the driving mechanism 300 to reset the clamping mechanism 200 to its initial position, preparing to process the next circuit board.
