Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing technology, specifically to an automatic feeding device for PCB manufacturing. Background Technology

[0002] PCBs are the carriers for electrical connections of electronic components and are an indispensable basic component in electronic devices. Among them, automatic feeding devices for PCB production are key equipment for realizing automated production in the field of electronic manufacturing. Automatic feeding devices for PCB production are usually composed of storage modules, conveying modules, positioning modules, drive modules, control modules, etc. Automatic feeding devices for PCB production are mainly used in the fields of smartphone production, automotive electronics manufacturing, and multilayer PCB processing.

[0003] For example, Chinese patent CN222081784U, entitled "A Feeding Device for PCB Board Processing," includes a conveyor belt. A feeding seat is installed on one side of the top of the conveyor belt, and a feeding groove is opened inside the feeding seat. Elastic plates are installed on both inner walls of the feeding groove, and a feeding box is installed on the top of the feeding seat. Mounting blocks are installed on one side of both sides of the conveyor belt, and side plates are installed on one end of both sets of mounting blocks. Sliding grooves are opened on the inner sides of both sets of side plates near the top. Electric push rods are installed on both sides of the top of the feeding seat, and the tops of both sets of electric push rods are installed with the bottom of the mounting plate.

[0004] While the existing technologies can achieve PCB board feeding, in practical use, the feeding and unloading of PCB boards are not efficient enough. Usually, PCB board feeding and unloading require segmented operations, which means that feeding can only be performed after the unloading operation is completed, thus reducing the efficiency of PCB board feeding. On the other hand, the clamping mechanism is not flexible enough. The clamping mechanism usually uses bolt drive, which causes the PCB board to wobble due to the insufficient movement accuracy of the bolts, thus reducing the stability of PCB board clamping. Therefore, it does not meet the current requirements. In response, we propose an automatic feeding device for PCB production. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding device for PCB production, so as to solve the problems mentioned in the background art of insufficient PCB feeding and unloading effect and insufficient flexibility of clamping mechanism adjustment.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can perform loading and unloading operations on PCB boards through the first moving frame and the second moving frame. When loading the PCB board, the PCB board has been clamped and fixed by the clamping mechanism. At this time, the first servo motor is turned on, so that the output shaft of the first servo motor drives the first lead screw to rotate. The first lead screw drives the connecting seat to move in the first slide groove. At the same time, the first moving frame fixed outside the connecting seat moves together. The PCB board is moved to a suitable position by the first moving frame. When unloading the PCB board, the PCB board has been clamped and fixed by the clamping mechanism. At this time, the first hydraulic telescopic device is turned on, so that the telescopic end of the first hydraulic telescopic device extends. The extension of the telescopic end of the first hydraulic telescopic device pushes the second moving frame to move inside the second slide groove until the second moving frame is moved to a suitable position. At this time, the clamping mechanism on the second moving frame is directly above the PCB board. The PCB board is then removed by the clamping mechanism on the second moving frame, thereby improving the efficiency of PCB loading and unloading.

[0015] (2) This utility model can stably clamp PCB boards through the second servo motor and the clamping plate. When loading PCB boards, the clamping mechanism on the first moving frame is adjusted according to the size of the PCB board. At this time, the second servo motor is turned on, so that the output shaft of the second servo motor drives the third lead screw to rotate. The third lead screw drives the clamping plate to move inside the clamping cavity until the rubber pad on the clamping plate contacts the side of the PCB board, completing the fixing of the PCB board before loading. Then the PCB board feeding operation is carried out. When unloading PCB boards, the clamping mechanism on the second moving frame is adjusted, and the fixing of the PCB board is released at the same time. The clamping plate is driven by the servo motor to clamp the PCB board, and then the PCB board is moved out from the support platform, thereby improving the clamping accuracy of the clamping mechanism on the PCB board.

[0016] (3) This utility model can fix the PCB board by means of a fixed plate and a third hydraulic telescopic device. When the PCB board is being processed, the PCB board is placed on the support platform and the outer sides of the PCB board are suspended. At this time, the operator opens the third hydraulic telescopic device, so that the telescopic end of the third hydraulic telescopic device extends. The extension of the telescopic end of the third hydraulic telescopic device drives the fixed plate to move towards each other in the third slide groove until the rubber pad on the fixed plate contacts the side of the PCB board, so that the PCB board is fixed on the support platform. Then the subsequent processing of the PCB board is carried out, thereby improving the stability of the PCB board processing. Attached Figure Description
