Description

Technical Field

[0001] This invention relates to the field of etching processing equipment technology, and more particularly to an etching frame and its processing equipment and process. Background Technology

[0002] An etched frame is formed by etching a substrate to create a substrate with leads, facilitating the integration of electronic components. During the etching process, an etching solution chemically reacts with the pre-treated substrate, corroding the untreated areas and thus completing the etching operation.

[0003] Chinese invention application number CN202111012626.0 discloses a precision etching module and precision etching apparatus and the etching process of the apparatus. The substrate is loaded and removed from the mounting slot of the module frame by a clamping device. In this method, the substrate cannot be installed at the same time as it is removed, which reduces the output rate, makes it impossible to form a production line etching operation, and reduces the etching efficiency. Summary of the Invention

[0019] Preferably, the bearing assembly includes an electric telescopic rod and a bearing plate. Two electric telescopic rods are symmetrically installed on both sides of the sealing block.

[0021] Preferably, the etching assembly includes a linear motor, a mounting bracket, a nozzle, and a connecting pipe. The linear motor is installed in the etching tank, and the output end of the linear motor is fixedly connected to the mounting bracket. The mounting bracket is slidably connected to the etching tank. The nozzle is fixedly connected to the mounting bracket, and one end of the nozzle is connected to the connecting pipe. The connecting pipe is a three-way pipe, and a first solenoid valve is installed at the three-way position. The first solenoid valve is a three-way solenoid valve. The end of the connecting pipe away from the nozzle is connected to an external etching solution supply source, and the other end is connected to an external cleaning solution supply source.

[0022] Preferably, the end of the nozzle away from the connecting pipe is connected to an air supply pipe, a second solenoid valve is installed on the air supply pipe, and the end of the air supply pipe away from the nozzle is connected to the output end of an external fan.

[0023] A processing method for an etching frame processing device includes the following steps:

[0024] S1: Place the pre-treated etched frame into the placement slot inside the sealing frame, and then place the sealing frame into the working slot on the sealing block;

[0025] S2: Two drive motors are started synchronously. The two drive motors drive two transmission belts through transmission rollers. The two transmission belts squeeze and contact the two sides of the sealing frame, thereby driving the sealing frame to move downward when the transmission belts move.

[0026] S3: Start the two electric telescopic rods. The output ends of the two electric telescopic rods are temporarily extended, pushing the support plate into the working groove. The drive motor works to move the sealing frame downwards until it falls on the support plate. At this time, the sealing frame forms a sealing effect on the bottom of the working groove.

[0027] S4: The external etching solution supply source is working. Etching solution is input into the nozzle through the connecting pipe. The linear motor drives the mounting frame to move linearly back and forth. During the first downward movement, the etching solution is sprayed on both sides of the etched frame from top to bottom to complete the etching operation.

[0028] S5: After the etching operation is completed, the external cleaning fluid supply source starts working, and during the first upward return stroke at the output end of the linear motor, the cleaning fluid is sprayed onto the etched frame after etching through the connecting pipe and the nozzle to complete the cleaning operation.

[0029] S6: After the cleaning operation is completed, the external fan works, and its output end outputs airflow downward through the air supply pipe and spray pipe to the etched frame after cleaning. In the second downward process at the output end of the linear motor, it blows away the water stains on the surface of the sealing frame and the etched frame, completing the water removal operation.

[0030] S7: The two drive motors continue to work, driving the sealing frame downwards through the transmission belt to move it out of the working groove and mating groove. The external collection device collects directly through the mating groove.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. This invention, by setting up a transmission mechanism, drives the sealing frame containing the etching frame to move through the working groove and the mating groove during operation, and completes the etching operation. There is no need to use a clamping device to clamp and remove the etched frame after etching. The etched frame can be directly pushed out through the working groove and the mating groove under the control of the transmission mechanism, which improves the output rate and can form a production line etching operation, thereby improving etching efficiency.

[0033] 2. This invention features multiple sealing blocks. When the sealing frame containing the etching frame is inside the working tank, it forms a seal at the bottom of the working tank, effectively preventing the etching liquid and cleaning liquid from leaking from the working tank. Multiple etching frames can be etched simultaneously, improving etching efficiency. Furthermore, the sealing blocks and corresponding etching components are set independently, allowing for targeted repairs in case of damage without affecting other components, facilitating maintenance and reducing the impact on production efficiency.

Separators 8 are provided at the four corners of the square central unit 3, and the four separators 8 are spaced apart from the four pins.

[0050] Reference Figures 3-6 An etching frame processing apparatus, comprising:

[0051] An etching tank 12 is provided, and multiple sealing blocks 13 are fixedly connected inside the etching tank 12. A working groove 14 is provided through the sealing block 13, and a mating groove 15 communicating with the working groove 14 is provided at the bottom of the etching tank 12.

[0052] The sealing block 13 is U-shaped. The working groove 14 includes a sliding groove 141 and a discharge groove 142. The two sliding grooves 141 are correspondingly opened on the inner sides of the top two ends of the sealing block 13. The discharge groove 142 is opened through the bottom of the sealing block 13. The bottoms of the two sliding grooves 141 and the discharge groove 142 are interconnected, which facilitates the rapid discharge operation through the sliding groove 141, the discharge groove 142 and the mating groove 15, and facilitates continuous processing operations, thereby improving processing efficiency.

[0053] The sealing frame 16, multiple sealing frames 16 and multiple working grooves 14 are sealed and slidably fitted one-to-one. The sealing frame 16 has a placement groove 17, which is used to place the etching frame, as described above.

[0054] When the sealing frame 16 is in working condition, it is located at the sliding groove 141, and the bottom of the sealing frame 16 is sealed to the top of the unloading groove 142, thereby effectively preventing the etching solution and cleaning solution from leaking into the unloading groove 142 and avoiding affecting the subsequent unloading operation.

[0058] Reference Figures 5-6 The transmission mechanism includes two symmetrical transmission components, each including a drive motor 21, a transmission roller 22, and a transmission belt 23. The drive motor 21 is mounted on the top of the etching tank 12. There are two transmission rollers 22 rotating on both sides of the etching tank 12. The same transmission belt 23 is sleeved on the two transmission rollers 22 on the same side. The output end of the drive motor 21 is coaxially and fixedly connected to one of the transmission rollers 22 on the same side. The two transmission belts 23 pass through the working groove 14 on both sides and abut against the sealing frame 16.

[0059] The etching components are connected in the etching tank 12 and correspond to the multiple sealing blocks 13. The output end of the etching components faces the etching frame on the sealing frame 16.

[0060] Both transmission belts 23 have an extrusion layer 24 fixedly connected to their inner sides. The extrusion layer 24 is extruded and fitted with the inner walls of the sliding groove 141 and the unloading groove 142. The extrusion layer 24 further increases the extrusion contact force between the transmission belt 23 and the sealing frame 16, thereby improving the driving control effect on the sealing frame 16.

[0061] Reference Figure 7 The etching assembly includes a linear motor 25, a mounting bracket 26, a nozzle 27, and a connecting pipe 28. The linear motor 25 is installed inside the etching tank 12. The output end of the linear motor 25 is fixedly connected to the mounting bracket 26, which is slidably connected inside the etching tank 12.

The end of the connecting pipe 28 away from the nozzle 27 is connected to an external etching solution supply source, and the other end is connected to an external cleaning solution supply source. The nozzle 27 has multiple nozzles, and the output direction of the multiple nozzles points to the etching frame on the sealing frame 16. When the first solenoid valve 29 is working, it controls the conduction state of the three-way connecting pipe 28.

[0062] The nozzle 27 is connected to an air supply pipe 30 at the end away from the connecting pipe 28. A second solenoid valve 31 is installed on the air supply pipe 30. The end of the air supply pipe 30 away from the nozzle 27 is connected to the output end of an external fan. The second solenoid valve 31 controls the conduction state of the air supply pipe 30.

[0064] S1: Place the pre-treated etched frame into the placement groove 17 inside the sealing frame 16, and then place the sealing frame 16 into the working groove 14 on the sealing block 13.

[0065] Among them, the front-mounted etching frame and sealing frame 16 can be operated by an external robotic arm, improving automation;

[0066] S2: Two drive motors 21 are started synchronously. The two drive motors 21 drive two transmission belts 23 through transmission rollers 22. The two transmission belts 23 press against both sides of the sealing frame 16, thereby driving the sealing frame 16 to move downward when the transmission belts 23 move.

[0067] S3: Start the two electric telescopic rods 18. The output ends of the two electric telescopic rods 18 are temporarily extended, pushing the support plate 19 into the working groove 14. The drive motor 21 works to drive the sealing frame 16 to move downwards until it falls on the support plate 19. At this time, the sealing frame 16 forms a sealing effect on the bottom of the working groove 14.

[0068] The support plate 19 is equipped with an induction switch. The contact between the sealing frame 16 and the support plate 19 is sensed, and the feedback control of the drive motor 21 is stopped to improve the accuracy of the working position of the sealing frame 16.

[0069] S4: The external etching solution supply source is working. Etching solution is input into the nozzle 27 through the connecting pipe 28. The linear motor 25 drives the mounting frame 26 to move linearly back and forth. During the first downward movement, the etching solution is sprayed on the etching frame on the sealing frame 16 from top to bottom to complete the etching operation.

[0070] Among them, two etching components correspond to one sealing block 13, forming a correspondence between the two sides of the etching frame body inside the sealing frame 16 on the sealing block 13. When the etching operation is performed, the first solenoid valve 29 works to connect the external etching liquid supply source and the nozzle 27.

[0071] S5: After the etching operation is completed, the external cleaning fluid supply source starts working, and during the first upward return stroke at the output end of the linear motor 25, the cleaning fluid is sprayed onto the etched frame after etching through the connecting pipe 28 and the nozzle 27 to complete the cleaning operation.

[0072] During the cleaning operation, the first solenoid valve 29 operates to connect the external cleaning material supply source and the nozzle 27.

[0073] S6: After the cleaning operation is completed, the external fan works, and its output end outputs airflow downward through the air duct 30 and the nozzle 27 to the etched frame after cleaning. In the second downward process at the output end of the linear motor 25, the water stains on the surface of the sealing frame 16 and the etched frame are blown away, and the water removal operation is completed.

[0074] During the dewatering operation, the first solenoid valve 29 closes the connecting pipe, and the second solenoid valve 31 connects the external fan output end and the nozzle 27.

[0075] S7: The two drive motors 21 continue to work, and drive the sealing frame 16 to move downward through the transmission belt 23 to move out of the working groove 14 and the mating groove 15. The external collection device collects directly through the mating groove 15.

[0076] After the dewatering operation is completed, the electric telescopic rod 18 drives the bearing plate 19 to retract from the working trough 14, making it convenient for material discharge.
