Description

Technical Field

[0001] The invention belongs to the field of plate exposure, and in particular relates to size-adaptive double-sided plate exposure equipment and a double-sided exposure method. Background Art

[0002] Sheet material exposure is one of the important processes in sheet material processing. For example, PCB (Printed Circuit Board) is an important carrier of various electronic components. Both sides of the PCB need to be exposed separately, such as laser direct writing exposure or photolithography of LDI.

[0003] Since both sides of the PCB board need to be exposed separately, after one side of the board is exposed, the board needs to be flipped using a flipping mechanism to expose the other side. The existing automated exposure equipment is too large in overall size, occupies a large area, the connection action CT is too long, and the overall production capacity is low. The exchange board process is complicated and two devices are required to expose both sides AB of the product. Moreover, traditional double-sided exposure machines generally target fixed board models or sizes, or require shutdown to manually change the distance to replace the corresponding picking or clamping mechanism for several different sizes, which undoubtedly leads to poor versatility and low efficiency of the equipment. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a size-adaptive double-sided exposure device and a double-sided exposure method for a plate, which can solve the above-mentioned problems.

[0005] Design principle: A dual-platform supporting single machine is used to expose both sides A and B of the product and directly produce the finished product; after the A side is exposed inside the single machine, the arm is connected and turned over to make the B side; a variable distance mechanism is used to automatically adjust and adapt to plates of different sizes.

[0006] A size-adaptive double-sided plate exposure device comprises a first loading and unloading station, a first conveying module, an exposure station, a second conveying module, and a second loading and unloading station; a flip module and a flip docking module are arranged between the first conveying module and the second conveying module; and an automatic size adjustment mechanism is arranged on the first conveying module, the second conveying module, the flip module, and the flip docking module.

[0007] Furthermore, the first loading and unloading station and the second loading and unloading station both include a roller streamline assembly, an in-position stop assembly and a clamping and positioning mechanism, which are used for rolling transmission and positioning of the plate; the first conveying module is arranged at the first loading and unloading station, and the second conveying module is arranged at the second loading and unloading station, which are used for picking up and conveying the plate between the loading and unloading station and the exposure station.

[0008] Furthermore, the flipping module is arranged adjacent to the inner side of the first loading and unloading station or the second loading and unloading station, and is used for picking up the plate with the first side exposed and flipping the plate; one side of the flipping and docking module is arranged adjacent to the downstream side of the flipping module, and the other side of the flipping and docking module is arranged adjacent to the second loading and unloading station or the first loading and unloading station, and the second transport module is used for picking up the plate with the second side exposed and transporting the plate for unloading.

[0009] Furthermore, the first transport module, the second transport module, the flip module and the flip docking module all include a lifting mechanism and a plate picking mechanism, and a transverse movement mechanism is also provided on the first transport module, the second transport module and the flip docking module.

[0010] Furthermore, the automatic size adjustment mechanism includes an adjustment motor, a screw rod and a slider. The automatic size adjustment mechanism is arranged at the picking profile frame of the plate picking mechanism. A fixed picking row group is arranged below the picking profile frame near the adjustment motor, and a sliding adjustment picking row group that slides with the slider is arranged below the slider.

[0011] The present invention also provides a double-sided exposure method for a plate. The double-sided exposure method is implemented based on the aforementioned double-sided exposure device for a plate. The double-sided exposure method includes the following steps.

[0012] S1, loading, the plate is transported from the loading car to the first loading and unloading station and positioned on the first loading and unloading station.

[0013] S2, material transfer: the first transport module picks up the plate on the first loading and unloading station and transports it to the first side to be exposed.

[0014] S3, front exposure: the transfer mechanism of the exposure station moves to the first side to be exposed position, picks up the plate on the first transfer module, and transfers it to the exposure position of the exposure station for front exposure.

[0015] S4, material transfer: the transfer mechanism of the exposure station transfers the plate after the front exposure to the first side to be exposed, the flip module picks up the plate and flips it, the flip docking module picks up the plate flipped by the flip module, and transports the flipped plate to the second side to be exposed.

[0016] S5, reverse side exposure: the transfer mechanism of the exposure station moves to the second side exposure position to dock and pick up the plate supplied by the flip docking module, and transfers it to the exposure position of the exposure station for reverse side exposure.

[0017] S6, material transfer: the transfer mechanism of the exposure station transfers the plate with the back side exposed to the second side to be exposed. The second transport module moves horizontally to pick up the plate with the back side exposed and transfers it to the second loading and unloading station.
