Description

Technical Field

[0001] The utility model belongs to the technical field of post-treatment of copper sheet cutting, and more specifically relates to a vision-assisted purging device. Background Art

[0002] Laser cutting is achieved by focusing a laser beam through a lens to form an extremely small light spot at the focal point. When a beam of sufficient power irradiates an object, the light energy is rapidly converted into heat energy, generating local high temperature to instantaneously melt or even vaporize the workpiece, thereby cutting the workpiece to the required depth or cutting through it.

[0003] PI film (i.e., polyimide film) is a polymer film with excellent high-temperature stability and chemical stability, and is usually used to prevent surface oxidation and protect the metal surface. Currently, residual PI film usually remains after laser cutting of copper sheets. Before use, the residual PI film on the copper sheets usually needs to be cleaned off. During the cleaning process, it is usually purged by manually holding an air gun. This purging method has a long purging time and low working efficiency, and needs to be improved. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a vision-assisted purging device, which has the advantages of reducing the purging duration and improving the purging efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A vision-assisted purging device includes a base. Along the length direction of the base, two guide rail frames are installed. Guide rails are installed on the guide rail frames. A clamping assembly for clamping a copper sheet is slidably installed on the guide rails. A driving assembly for driving the clamping assembly is installed below the base.

[0007] A loading table, a transfer table and an unloading table are installed between the two guide rails. A vision detection assembly is installed directly above the loading table. An inverted U-shaped frame is installed on the base frame. The inverted U-shaped frame is located between the loading table and the transfer table. A purging assembly is installed on the inverted U-shaped frame.

[0008] The advantages of this solution are at least as follows: When purging a copper sheet after laser cutting, place the cut copper sheet on the loading table, start the clamping assembly to clamp the copper sheet. At this time, the vision detection assembly detects and records the position of the PI film on the copper sheet. Then start the driving assembly to drive the clamping assembly to move on the guide rail. When the driving assembly drives the clamping assembly to move directly below the purging assembly, the purging assembly purges the detected position of the PI film on the copper sheet, reducing the purging duration and improving the purging efficiency.

[0009] The present utility model is further configured as follows: The clamping assembly includes two vertical plates fixedly installed on the driving assembly, and pneumatic grippers are installed on the side walls of the vertical plates.

[0010] The advantages of this solution are at least as follows: The pneumatic gripper can accurately control the clamping force, has a small volume, is easy to operate, has good stability, and has relatively low difficulty in later maintenance.

[0011] The present utility model is further configured as follows: The purging assembly includes a mounting plate and a blowing plate, the mounting plate and the blowing plate are integrally formed, several through holes are formed in the blowing plate, one end of each through hole is connected to a nozzle, the other end is connected to a trachea through a trachea joint, a pneumatic solenoid valve is provided at the end of the trachea, the input end of the pneumatic solenoid valve is connected to an air compressor through a trachea, and the pneumatic solenoid valve and the vision detection assembly are electrically connected through an electric wire and a controller.

[0012] The advantages of this solution are at least as follows: After the vision detection assembly detects and records the position of the PI film, the recorded position of the vision detection assembly is transmitted to the controller, and the pneumatic solenoid valve is controlled by the controller to accurately purge the PI film on the copper sheet, reducing the purging time and improving the purging efficiency.

[0013] The present utility model is further configured as follows: High-quality rubber pads are pasted on the contact surfaces of the two output ends of the pneumatic gripper.

[0014] The advantages of this solution are at least as follows: The high-quality rubber pads prevent the output ends of the pneumatic gripper from directly contacting the product, thereby avoiding damage to the product caused by excessive clamping force during the clamping process of the pneumatic gripper.

[0015] The present utility model is further configured as follows: A proximity switch sensor is installed on the base, the proximity switch sensor includes a first proximity switch, a second proximity switch and a third proximity switch, and an induction sheet is installed on the drive.

[0016] The advantages of this solution are at least as follows: The settings of the first proximity switch and the second proximity switch facilitate the detection of the extreme positions of the driving assembly and play a role in limiting the driving assembly, while the setting of the third proximity switch facilitates the control of releasing the clamping assembly to ensure that the copper sheet can be accurately placed on the transfer table and the blanking table after the clamping assembly is released.

[0017] The present utility model is further configured as follows: The proximity switch sensor and the driving assembly and the clamping assembly are electrically connected through an electric wire and a controller.

[0018] In summary, the present utility model has at least the following advantages:

[0019] 1. By setting up a clamping component, a driving component, a vision detection component, and a purging component, when it is necessary to purge the copper sheet after laser cutting, place the cut copper sheet on the loading table, start the clamping component to clamp the copper sheet. At this time, the vision detection component detects and records the position of the PI film on the copper sheet. Then start the driving component to drive the clamping component to move on the guide rail. When the driving component drives the clamping component to move directly below the purging component, the purging component purges the detected position of the PI film on the copper sheet, reducing the purging duration and improving the purging efficiency.

[0020] 2. By setting up a blowing plate, air nozzles, and pneumatic solenoid valves and combining them with the vision detection component, after the vision detection component detects and records the position of the PI film, transmit the recorded position to the controller, and control the pneumatic solenoid valves through the controller to accurately purge the PI film on the copper sheet, reducing the purging duration and improving the purging efficiency.

[0021] 3. By setting up urethane rubber pads, the urethane rubber pads prevent the output end of the pneumatic gripper from directly contacting the product, thus avoiding damage to the product caused by excessive clamping force during the clamping process. The setting of the first proximity switch and the second proximity switch facilitates the detection of the limit positions of the driving component and plays a role in limiting the driving component. The setting of the third proximity switch facilitates controlling the release of the clamping component to ensure that the copper sheet can be accurately placed on the transfer table and the unloading table after the clamping component is released.

Detailed implementation

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] A vision-assisted purging device, as Figure 1 , Figure 2 shown, includes a base 1, on which two guide rail frames 2 are installed along its length direction. A guide rail 3 is installed on the guide rail frame 2, and a clamping assembly 4 for clamping the copper sheet 15 is slidably installed on the guide rail 3. A drive assembly 5 for driving the clamping assembly 4 is installed below the base 1. The drive assembly 5 is composed of a motor, a lead screw key-connected to the motor, and a slider threadedly connected to the lead screw and only capable of linear movement in cooperation with the slide rail. In other embodiments, the drive assembly 5 can also be a cylinder or an oil cylinder.

[0030] A loading table 6, a transfer table 7, and an unloading table 8 are installed between the two guide rails 3. A vision inspection assembly 9 is installed directly above the loading table 6. The vision inspection assembly 9 belongs to the prior art and will not be elaborated here. An inverted U-shaped frame 10 is installed on the base frame, and the inverted U-shaped frame 10 is located between the loading table 6 and the transfer table 7. A purging assembly 11 is installed on the inverted U-shaped frame 10.

[0031] As Figure 2 , Figure 3 shown, the clamping assembly 4 includes: two vertical plates 401 fixedly installed on the drive assembly 5. A pneumatic gripper 402 is installed on the side wall of the vertical plate 401. The pneumatic gripper 402 makes the clamping assembly 4 easy to operate, has good stability, and has less difficulty in later maintenance. It is worth mentioning that urethane rubber pads 12 are pasted on the contact surfaces of the two output ends of the pneumatic gripper 402, and the urethane rubber pads 12 can prevent the pneumatic gripper 402 from damaging the product due to excessive clamping force during the clamping process.

[0032] As Figure 4As shown, in order to ensure that the purging assembly 11 can accurately purge the PI film on the copper sheet 15, in some embodiments, the purging assembly 11 includes a mounting plate 1101 and a blowing plate 1102. The mounting plate 1101 and the blowing plate 1102 are integrally formed. A plurality of through holes 1103 are formed in the blowing plate 1102. One end of each through hole 1103 is connected to a nozzle 1104, and the other end is connected to a trachea 1105 through a trachea joint (not shown in the figure). The end of the trachea 1105 is communicated with an air compressor (not shown in the figure) through a pneumatic solenoid valve (not shown in the figure). The pneumatic solenoid valve is electrically connected to the vision detection assembly 9 and the controller through wires.

[0033] As Figure 5 shown (refer to Figure 2 ), in order to ensure that the clamping assembly 4 can accurately place the purged copper sheet 15 on the transfer table 7 and the blanking table 8, in some embodiments, a proximity switch sensor 13 is installed on the base 1. The proximity switch sensor 13 includes a first proximity switch 1301, a second proximity switch 1302, and a third proximity switch 1303. An induction sheet 14 is installed on the driving assembly 5. The proximity switch sensor 13 is electrically connected to the driving assembly 5 and the clamping assembly 4 through wires and the controller.

[0034] The working process and beneficial effects of the present utility model are as follows:

[0035] When it is necessary to purge the copper sheet 15 after laser cutting, the cut copper sheet 15 is placed on the loading table 6, and the pneumatic gripper 402 is started to clamp the copper sheet 15. The vision detection assembly 9 detects and records the position of the PI film on the copper sheet 15. Then the driving assembly 5 is started to drive the clamping assembly 4 to move on the guide rail 3. At this time, the driving assembly 5 drives the clamping assembly 4 to move to directly below the blowing plate 1102, and transmits the position recorded by the vision detection assembly 9 to the controller. The pneumatic solenoid valve is controlled by the controller to accurately purge the PI film on the copper sheet 15 through the nozzle 1104, reducing the purging duration and improving the purging efficiency.

[0036] When the driving assembly 5 moves to a certain position, the induction sheet 14 on the driving assembly 5 is sensed by the third proximity switch 1303. The driving assembly 5 is controlled by the controller to stop moving and the clamping assembly 4 is controlled to release, placing the purged copper sheet 15 on the transfer table 7 and continuing to move forward. When the induction sheet 14 is sensed by the second proximity switch 1302, the driving assembly 5 reverses and returns to the starting position. When the induction sheet 14 is sensed by the first proximity switch 1301, it stops moving. Repeat the above actions. When clamping the copper sheet 15 to be purged, the purged copper sheet 15 on the transfer table 7 will be clamped at the same time. The copper sheet 15 to be purged is moved to below the blowing plate 1102 for purging. When moving the purged copper sheet 15 to the transfer table 7, the copper sheet 15 on the transfer table 7 is also moved to the blanking table 8.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
