Description

[Technical field]

[0001] The utility model relates to a transfer technology of a PCB board, in particular to a board frame for carrying and transferring a PCB board. [Background technology]

[0002] In the process of PCB board processing and production, a large number of specialized machines and equipment are needed to process and assemble PCB boards. Especially in the process of loading and unloading PCB boards, a large number of board loaders and board delivery machines are needed to facilitate the automatic transmission of PCB boards.

[0003] However, in the existing PCB preparation process, firstly, it is required that PCB boards cannot collide with each other and can only be placed on trays or fixtures; secondly, due to the increasing use of high-precision plate output equipment such as gravure plates, pad printing plates and precision etching, the PCB boards are generally carried one by one by the board loading machine and the board feeding machine on the production line through the corresponding process workstation. This requires that each PCB board be positioned and fixed one by one by a tray or fixture before etching or cleaning, so as to facilitate automatic up and down transportation, automatic fast and accurate detection and positioning during plasma etching or plasma cleaning.

[0004] However, in the current processing, the existing pallets or fixtures cannot effectively guarantee the assembly quality of the PCB boards, and various problems arise during the transportation process. [Utility Model Content]

[0005] The embodiment of the utility model provides a plate frame for carrying PCB boards for transportation, which can carry multiple PCB boards at one time, facilitates automatic positioning and loading and unloading transportation of the main plate frame, saves manpower and material resources, and effectively improves processing quality and processing efficiency.

[0006] The technical solution adopted by at least one embodiment of the utility model is:

[0007] A plate frame for carrying PCB board transfer, used for synchronous transfer after supporting and fixing multiple PCB boards, including a main plate frame:

[0008] The plate surface of the main body frame is provided with at least four square through holes distributed in an array and respectively supporting and fixing each PCB board, and the periphery of the outer edge of the square through hole forms a step-shaped stepped table surface that cooperates with the periphery of each PCB board and fixes and limits the periphery of each PCB board in the horizontal direction;

[0009] At least three groups of PCB board self-locking clamps evenly distributed along the circumferential direction are arranged on the circumferential side edges of each square through hole on the main body frame. All the PCB board self-locking clamps around each square through hole are opened and synchronously made way under the drive of external force to overcome the self-locking torque and are used to place the PCB board on the stepped table surface on the main body frame, and are synchronously pressed and locked to the PCB board placed on the main body frame under the action of their own self-locking torque.

[0010] Preferably, the front and rear edges of the main body plate frame along the transport direction are respectively provided with two traction holes for pulling the entire plate body to move forward and backward during transport.

[0011] Preferably, at least two evenly distributed limit locking holes are provided in the middle of the main body frame, which are used to facilitate the upward limit locking of the main body frame by external force when all the PCB board self-locking clamps overcome the self-locking torque and open under the drive of external force.

[0012] Preferably, each group of the PCB board self-locking clamps includes a hinged pressure plate and a self-locking torsion spring, and the self-locking torsion spring is installed at the hinge of the hinged pressure plate. The self-locking torsion spring self-expands and drives the front free end of the hinged pressure plate to press and lock the PCB board placed on the stepped table on the main body frame.

[0013] Preferably, a strip-shaped round convex pressing head for pressing the PCB board is provided on the lower side of the front free end, which protrudes downward relative to the stepped platform.

[0014] Preferably, the main body frame is a square frame-shaped plate body, and the four corners of the stepped table of each square through hole are respectively recessed with avoidance grooves to prevent contact with the four corners of the PCB board.

[0015] Preferably, each of the square through holes is respectively provided with four recessed grooves at the four corners of the outer edge thereof for making way for the PCB board, facilitating the passage of the gripper component, and used for clamping and lifting and shifting the PCB board after the PCB board self-locking clamp releases the lock on the PCB board.

[0016] The beneficial effects of the utility model are:

[0017] All the PCB self-locking clamps on the outer edge of each square through hole on the main body frame cooperate effectively to fix the PCB in each square through hole. During the transportation of the PCB, the PCB is effectively protected to prevent damage to the PCB caused by various collisions.

[0018] Moreover, the main body frame effectively improves the flatness and stability of the PCB board, making it easier to position the PCB board during subsequent processing, thereby effectively improving subsequent processing accuracy and efficiency.
