[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: Figure 1-Figure 3 and Figure 10 As shown, a processing and assembly device for etching machine pallets includes a box body 100, multiple water tanks 105, two sets of flushing mechanisms 110, a pallet clamping mechanism 200 and a driving mechanism 300.

[0037] The top of the box 100 is open, and a partition is installed inside the box 100. The partition divides the interior space of the box 100 into an etching tank 101 and a rinsing tank 102. The etching tank 101 is used to hold etching liquid and is equipped with two racks 104. A drainage pipe is installed on the box 100 and communicates with the rinsing tank 102. Two guide grooves 103 are provided on the inner wall of the box 100.

[0038] The multiple water tanks 105 are all installed on the bottom surface of the box body 100; the multiple water tanks 105 are connected by connecting pipes 106, so that the multiple water tanks 105 are interconnected.

[0039] A bracket 107 is also mounted on the housing 100, which is used to hold the circuit board. Two flushing mechanisms 110 are also mounted on the housing 100. The card clamping mechanism 200 includes a clamping assembly 210 and a liquid mixing assembly 220. The clamping assembly 210 is used to clamp and secure the circuit board. A drive mechanism 300 is used to drive the card clamping mechanism 200.

[0040] Specifically, etching solution 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 mechanism 200.

[0041] Then, the driving mechanism 300 is started to drive the card board clamping mechanism 200 to move. When the card board clamping mechanism 200 moves in the etching tank 101, the etching liquid contacts the circuit board and etches the circuit board. When the card board clamping mechanism 200 moves in the etching tank 101, the liquid mixing component 220, under the influence of the rack 104, stirs the etching liquid in the etching tank 101, thereby avoiding stratification and segregation of the etching liquid and improving the etching effect.

[0042] When the card clamping mechanism 200 moves in the rinsing tank 102, the liquid mixing component 220 drives the two sets of rinsing mechanisms 110 to operate, so that the rinsing mechanisms 110 pump out water in the water tank 105 and spray it on the circuit board to rinse the circuit board after etching.

[0043] like Figure 3 and Figure 10 As shown, the card clamping mechanism 200 further includes a mounting seat 201 and two first telescopic rods 202 , and the two first telescopic rods 202 are both mounted on the bottom surface of the mounting seat 201 .

[0044] Specifically, by providing the first telescopic rod 202 , when the card clamping mechanism 200 moves along the guide groove 103 , the provision of the first telescopic rod 202 can allow the clamping assembly 210 and the liquid mixing assembly 220 to move up and down.

[0045] like Figure 3 and Figure 4 As shown, the clamping assembly 210 includes a support plate 211, two movable plates 212, a plurality of second telescopic rods 216, two clamping plates 217, a plurality of second springs 218 and an adjusting component.

[0046] The supporting plate 211 is installed on the extended ends of the two first telescopic rods 202; the two movable plates 212 are respectively slidably connected to the two supporting plates 211; multiple second telescopic rods 216 are respectively installed on the opposite sides of the two movable plates 212; two clamping plates 217 are respectively connected to the extended ends of the multiple second telescopic rods 216, and the two clamping plates 217 are used to clamp and fix the circuit board; multiple second springs 218 are respectively mounted on the multiple second telescopic rods 216; the adjusting component is used to adjust the distance between the two movable plates 212.

[0047] Specifically, the two movable plates 212 are driven to move by the adjusting component, and then the two clamping plates 217 are driven to move, so that the two clamping plates 217 can clamp and fix circuit boards of different sizes. The clamping assembly 210 clamps and buffers the circuit board through the support plate 211, the movable plate 212, the second telescopic rod 216, the clamping plate 217 and the second spring 218, ensuring the stability and safety of the clamping.

[0048] like Figure 3 and Figure 5 As shown, the liquid mixing assembly 220 includes two vertical plates 221 , two cylinders 222 , two spiral stirring rods 223 , two spiral stirring rods 223 , a crossbar 224 , two first bevel gears 225 , two second bevel gears 226 and two gears 227 .

[0049] The two vertical plates 221 are fixedly connected to the mounting base 201; the two cylinders 222 are respectively mounted on the two vertical plates 221, and the top and bottom of the cylinders 222 are both open. The two spiral stirring rods 223 are rotatably mounted in the two cylinders 222; the crossbar 224 is rotatably connected to the two vertical plates 221, and the ends of the crossbar 224 are respectively slidably connected to the guide grooves 103 provided on the inner wall of the box body 100; the two first bevel gears 225 are fixedly mounted on the crossbar 224; the two second bevel gears 226 are respectively mounted on 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 fixedly mounted on the crossbar 224, and the two gears 227 match the two racks 104.

[0050] 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 transport the etching liquid at the bottom of the cylinder 222 upward, thereby turning the etching liquid, avoiding stratification and segregation of the etching liquid, and improving the etching efficiency.

[0051] like Figure 1 、 Figure 6 and Figure 7 As shown, the flushing mechanism 110 includes a piston cylinder 111 , a semicircular tooth plate 113 , a first spring 114 , a hollow plate 117 and a plurality of spray heads 118 .

[0052] The piston cylinder 111 is installed on the box body 100, and a piston plate is slidably connected inside the piston cylinder 111. A piston rod 112 slidably connected to the piston cylinder 111 is installed on the piston plate. A water extraction pipe 115 and a water supply pipe 116 are installed at the bottom of the piston cylinder 111, and the other end of the water extraction pipe 115 is connected to the water tank 105.

[0053] The semicircular tooth plate 113 is installed on the upper end of the piston rod 112, and the semicircular tooth plate 113 matches the gear 227; the first spring 114 is sleeved on the piston rod 112; the two ends of the first spring 114 are fixedly connected to the semicircular tooth plate 113 and the piston cylinder 111 respectively.

[0054] The hollow plate 117 is installed on the box body 100 , and the hollow plate 117 is connected to the water pipe 116 ; multiple nozzles 118 are installed on the hollow plate 117 , and the multiple nozzles 118 extend into the box body 100 .

[0055] One-way valves are installed in both the water extraction pipe 115 and the water delivery pipe 116, so that the water in the water tank 105 can only enter the piston cylinder 111 in one direction through the water extraction pipe 115, and the water in the piston cylinder 111 can only enter the hollow plate 117 in one direction through the water delivery pipe 116.

[0056] Specifically, when the semicircular tooth plate 113 moves downward, it drives the piston rod 112 and the piston plate to move, thereby transporting the water in the piston cylinder 111 to the hollow plate 117 through the liquid delivery tube;

[0057] When the semicircular tooth plate 113 moves upward, it drives the piston rod 112 and the piston plate to move upward, thereby causing the piston cylinder 111 to extract water from the water tank 105 through the water extraction pipe 115 .

[0058] The semicircular tooth plate 113 can automatically reset by providing a first spring 114. By reciprocatingly pressing and releasing the semicircular tooth plate 113, the piston cylinder 111 will continuously extract water from the water tank 105 under the cooperation of the first spring 114, and continuously transport the water into the hollow plate 117, so that the air in the hollow plate 117 is sprayed out through multiple nozzles 118.

[0059] like Figure 4 As shown, the adjustment component includes two first screw nuts 213 , a first screw 214 , a first motor 215 , a third spring 2171 , an extrusion plate 2172 , a pressure sensor 2121 and a controller 219 .

[0060] The two first lead screw nuts 213 are respectively installed on the two movable plates 212; the first lead screw 214 is installed on the two first lead screw nuts 213, and the textures at both ends of the first lead screw 214 are set in opposite directions; the first motor 215 is installed on the bottom surface of the support plate 211, and the power output shaft of the first motor 215 is fixedly connected to the first lead screw 214; the third spring 2171 is installed on the clamping plate 217; the extrusion plate 2172 is fixedly connected to the third spring 2171; the pressure sensor 2121 is installed on the movable plate 212, and the pressure sensor 2121 faces the extrusion plate 2172; the controller 219 is installed on the support plate 211, and the controller 219 is used to shut down the operation of the first motor 215.

[0061] The controller 219 is used to receive 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 equidistant from the preset pressure threshold, the controller 219 controls the operation of the first motor 215 to be shut down.

[0062] Specifically, a pressure threshold is preset on the controller 219. Then, the circuit board is placed on the bracket 107, where the circuit board is located between the two clamping plates 217. The first motor 215 is started 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 movable plates 212, and further adjusting the distance between the two clamping plates 217, so that the two clamping plates 217 clamp the circuit board.

[0063] At this time, the splint 217 will also move toward the direction close to the movable plate 212, thereby driving the extrusion plate 2172 to move toward the direction close to the pressure sensor 2121, thereby causing the extrusion plate 2172 to squeeze 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 the shutdown of the first motor 215 to prevent damage to the circuit board.

[0064] It should be noted that the relationship between the extrusion force on the circuit board and the pressure on the pressure sensor 2121 can be obtained by technicians in this field based on actual conditions and a large amount of data simulation.

[0065] like Figure 8 As shown, the driving mechanism 300 includes a first frame 301 , a second frame 302 , a second motor 303 , a second lead screw 304 and a second lead screw nut 305 .

[0066] The first frame 301 is installed on one side of the box body 100; the second frame 302 is installed on the other side of the box body 100; the second motor 303 is installed on the second frame 302; the second screw 304 is installed on the power output shaft of the second motor 303, and the second screw 304 is rotatably connected to the first frame 301 and the second frame 302; the second screw nut 305 is sleeved on the second screw 304, and the second screw nut 305 is fixedly connected to the mounting base 201.

[0067] Specifically, when the second motor 303 is running, it drives 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 thereby driving the entire card clamping mechanism 200 to move.

[0068] like Figure 1 As shown, when the crossbar 224 moves along the guide groove 103, the gear 227 engages with the rack 104 and the semicircular toothed plate 113. When the gear 227 engages with the rack 104, it drives the liquid mixing assembly 220 to operate; when the gear 227 engages with the semicircular toothed plate 113, it pushes the semicircular toothed plate 113 downward, thereby driving the flushing mechanism 110 to spray water, thereby improving the automation level of the equipment.

[0069] like Figure 1 、 Figure 2 and Figure 9 As shown, the processing and assembly equipment of the etching machine pallet also includes a blower mechanism 400, which includes a fixed cylinder 401, an air guide pipe 402, an air outlet slot 403, a fixed frame 404, a third motor 405 and blades 406.

[0070] The fixed cylinder 401 is mounted on the second frame 302; the air duct 402 is mounted on the fixed cylinder 401; the air outlet slot 403 is opened on the air duct 402; the fixed frame 404 is mounted in the fixed cylinder 401; the third motor 405 is mounted on the fixed frame 404; the blade 406 is mounted on the power output shaft of the third motor 405.

[0071] Specifically, when the third motor 405 is running, it will drive the blade 406 to rotate, thereby transporting air into the air duct 402. The air in the air duct 402 will be blown out through the air outlet slot 403. The air blown out of the air outlet slot 403 will blow toward the circuit board, thereby achieving rapid drying of the circuit board and improving production efficiency.

[0072] Working principle: When in use, the circuit board to be etched is placed on the bracket 107, and the circuit board is between the two clamping plates 217;

[0073] Then, start the first motor 215 to drive the first screw 214 to rotate, thereby driving the two first screw nuts 213 to move simultaneously in opposite directions, thereby adjusting the distance between the two movable plates 212, and then 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.

[0074] Then, the second motor 303 is started. When the second motor 303 is running, it will drive the second screw 304 to rotate, thereby causing the second screw nut 305 to move horizontally, thereby driving the mounting seat 201 to move horizontally, and thereby driving the entire card clamping mechanism 200 to move along the two guide grooves 103.

[0075] When the card board clamping mechanism 200 moves in the etching tank 101, the etching liquid contacts the circuit board and etches the circuit board; and when the card board clamping mechanism 200 moves in the etching tank 101, the gear 227 in the liquid mixing component 220 will engage with the rack 104. Under the influence of the rack 104, the gear 227 will start to rotate, thereby driving the cross bar 224 to rotate, and then 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 liquid at the bottom of the cylinder 222 upward, thereby turning the etching liquid, avoiding stratification and segregation of the etching liquid, and improving the etching efficiency.

[0076] 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 semicircular tooth plate 113 and push the semicircular tooth plate 113 to move downward, thereby driving the piston rod 112 and the piston plate to move downward, and then 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.

[0077] Then, start the second motor 303, so that the second motor 303 drives the second screw 304 to rotate counterclockwise, and then drives the card clamping mechanism 200 to move toward the direction close to the first frame 301, so that the card clamping mechanism 200 is between the first frame 301 and the semicircular tooth plate 113, and then control the second motor 303 to drive the second screw 304 to rotate clockwise, so that the gear 227 will contact the semicircular tooth plate 113 and push the semicircular tooth plate 113 to move downward, so that the water sprayed from the nozzle 118 rinses the circuit board, and repeat the above operation so that the nozzle 118 continuously rinses the circuit board, thereby rinsing away the residual etching liquid on the circuit board.

[0078] Then, the second motor 303 is controlled to drive the second lead screw 304 to rotate clockwise, so that the card clamping mechanism 200 is moved out of the rinsing tank 102. The second motor 303 is then turned off, and the third motor 405 is started. When the third motor 405 is running, it drives the blade 406 to rotate, thereby conveying air into the air duct 402. The air in the air duct 402 is blown out through the air outlet slot 403. The air blown out of the air outlet slot 403 is blown toward the circuit board, thereby achieving rapid drying of the circuit board and improving production efficiency.

[0079] After the circuit board is dried, the first motor 215 is started to drive the first screw 214 to move, thereby driving the two first screw nuts 213 to move in opposite directions at the same time, thereby driving the two movable plates 212 and the clamping plate 217 to move in opposite directions, thereby facilitating the removal of the circuit board.

[0080] After completing the above operations, by starting the second motor 303, the power output shaft of the second motor 303 drives the second screw 304 to rotate counterclockwise, so that the card clamping mechanism 200 moves toward the direction close to the first frame 301, and the card clamping mechanism 200 is reset to facilitate etching of subsequent circuit boards.

[0081] Example 2: Figures 1-10 As shown, a method for using an etching machine pallet processing and assembly device includes the following steps:

[0082] 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;

[0083] Step 2: Place the circuit board to be etched on the bracket 107, ensure that the circuit board is positioned correctly, start the first motor 215, drive the first screw 214 to rotate, and then drive the two first screws 214 and nuts 213 to move in opposite directions simultaneously, thereby adjusting the distance between the two movable plates 212, and then drive the two clamping plates 217 to move until the clamping plates 217 firmly clamp the circuit board;

[0084] Step 3: Start the second motor 303 to drive the second lead screw 304 to rotate, thereby causing the nut of the second lead screw 304 to move horizontally, thereby driving the entire card clamping mechanism 200 to move along the guide groove 103; when the card clamping mechanism 200 enters the etching tank 101, the etching liquid will come into contact with the circuit board, and the etching liquid will etch the circuit board; at the same time, the gear 227 in the liquid mixing component 220 engages with the rack 104, driving the spiral stirring rod 223 to rotate. The rotating spiral stirring rod 223 transports the etching liquid in the lower part of the etching tank 101 upward, thereby turning the etching liquid, avoiding stratification and segregation of the etching liquid, and improving the etching effect;

[0085] Step 4: As the drive mechanism 300 continues to operate, the card 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 semicircular toothed plate 113 of the flushing mechanism 110 and pushes the semicircular toothed plate 113 downward. The movement of the semicircular toothed plate 113 drives the piston rod 112 and the piston plate downward, transporting the water in the piston cylinder 111 through the water pipe 116 to the hollow plate 117. The water is then sprayed out by the multiple nozzles 118 to flush the circuit board.

[0086] Step 5: Control the driving mechanism 300 to repeatedly move the card clamping mechanism 200 as needed to achieve multiple flushing to ensure that the etching solution residue on the surface of the circuit board is thoroughly rinsed;

[0087] Step 6: After the card clamping mechanism 200 is moved out of the rinsing tank 102, the second motor 303 is turned off, and the third motor 405 is started, which drives the blades 406 to rotate, transporting air into the air duct 402. The air in the air duct 402 is blown out through the air outlet slot 403 and blown toward the circuit board to achieve rapid drying. After drying, the circuit board is removed from between the two clamping plates 217.

[0088] Step 7: Start the driving mechanism 300 and reset the card clamping mechanism 200 to the initial position, preparing to process the next circuit board.
