Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of PCB board production, specifically relates to a PCB board carrier tray. BACKGROUND

[0002] In the PCB board production, test or repair process, the carrier tray is a core auxiliary tool for fixing, transporting and positioning multiple PCB boards. The traditional tray usually adopts the clamping structure of flexible card grid to realize the side-by-side loading of multiple PCB boards. However, in actual application, such tray often needs the operator to manually take and place each PCB board one by one in the plate removal link, which is low in efficiency and easy to cause PCB board scratch or buckle structure damage due to operation error.

[0003] Therefore, further, the prior art sets up the plate lifting capable of lifting on the card format tray, and the edge and corner of multiple PCB boards are contacted with the lifting plate at the same time, and then the plate is removed in batches by lifting the lifting plate.

[0004] However, the plate removal mode of the lifting plate usually applies force on the two end edges of the PCB, so that in actual use, the plate body cannot be completely taken off due to uneven force on both sides, resulting in low plate removal efficiency. UTILITY MODEL CONTENTS

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 2 As shown, this utility model provides a PCB board carrier tray, including a pair of symmetrically arranged frame plates 1. The frame plates 1 are made of high-strength engineering plastic or metal materials to ensure structural stability and durability. Multiple locking strips 2 are equidistantly arranged along the length of the upper surface of the frame plates 1. The number of locking strips 2 can be adjusted according to the actual loading requirements of the PCB boards, for example, one, two, or more. Each locking strip 2 is provided with a slot 3, which is a groove structure whose shape and size are adapted to the edge of the PCB board to be loaded. Adjacent locking strips 2 are connected and fixed to the PCB board through the slot 3, thereby realizing the side-by-side loading of multiple PCB boards.

[0023] A movable rod 4 is fixedly connected to the corner of the frame plate 1. The movable rod 4 is preferably a cylindrical metal rod, and its top end is fixed to the bottom of the frame plate 1 by welding or threading. An elastic element is connected to the bottom end of the movable rod 4. The elastic element can be a spring or a rubber elastomer, used to provide compression and reset functions. The elastic element is set inside the fixed sleeve rod 5. The fixed sleeve rod 5 is a hollow cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the movable rod 4, so that the movable rod 4 can slide axially within the fixed sleeve rod 5. A flat plate 6 is fixedly installed at the bottom of the fixed sleeve rod 5.

[0024] Multiple lifting blocks 7 are evenly spaced on the upper surface of the planar plate 6. The number of lifting blocks 7 corresponds to the number of gaps between adjacent clips 2. For example, if there are 10 gaps between clips 2, then 10 lifting blocks 7 are provided. The height and width of the lifting blocks 7 are designed according to the size of the PCB board. The top of the lifting block 7 is preferably set as an arc shape with a buffer pad to avoid scratching the PCB board during the lifting process. The multiple lifting blocks 7 are respectively set in the gaps between adjacent clips 2. When the operator presses the frame plate 1 to move the clips 2 downward, the movable rod 4 compresses the elastic element and slides along the fixed sleeve rod 5, so that the lifting blocks 7 lift the middle main body of the PCB board upward, thereby realizing the batch unloading of the PCB board.

[0025] like Figure 1As shown, the side of the frame plate 1 is provided with a wing block 8, which is rectangular, trapezoidal or semicircular structure, fixed to the side of the frame plate 1 by bolts or one-piece, for easy to grasp the frame plate 1 to achieve the down. The bottom of the wing block 8 is rotatably connected with a support column 9 through a rotating joint, which can be a hinge or a rotating shaft structure, so that the support column 9 can rotate around the symmetry axis of the width direction of the flat plate 6. When the card strip 2 needs to be pressed down, the support column 9 is rotated to one side to smoothly press down the frame plate 1 and the card strip 2. When normal loading and unloading, the support column 9 is rotated to the vertical state, connected with the flat plate 6, forming a support for the frame plate 1, thereby providing support force for the PCB board on the one hand, and preventing accidental touch on the other hand, causing false unloading.

[0026] The bottom end face of the support column 9 is provided with a magnetic sheet 10, which is made of permanent magnet material, such as neodymium iron boron magnet. The flat plate 6 is provided with a connecting sheet 11 at a position corresponding to the bottom end face of the support column 9, which is made of ferromagnetic material and can be adsorbed with the magnetic sheet 10. When the support column 9 is rotated to contact with the flat plate 6, the magnetic sheet 10 and the connecting sheet 11 are adsorbed and fixed, so that the support column 9 returns to the vertical state more conveniently without manual adjustment.

[0027] As shown in Figure 1 The edge of the flat plate 6 is provided with a fixed rod 12, which is a vertical cylindrical rod, and the bottom end is fixed on the flat plate 6 by welding or bolt. The top end of the fixed rod 12 is provided with a T-shaped sliding block 13. The T-shaped sliding block 13 is slidably provided with an inverted bottom plate 14, which is a rectangular plate structure with a width and length sufficient to cover all the card strips 2. The inverted bottom plate 14 is slidably connected with the T-shaped sliding block 13 through the sliding groove on the side of the inverted bottom plate 14, so as to slide in the horizontal direction on the T-shaped sliding block 13 to cover or expose the card strips 2.

[0028] As shown in Figure 2 When the PCB board needs to be unloaded, the entire tray can be turned over, so that the PCB board falls on the inverted bottom plate 14, and then the T-shaped sliding block 13 and the inverted bottom plate 14 are slidably connected, and the entire tray is slid to one side, so that all the unloaded PCB boards on the inverted bottom plate 14 are exposed, making it more convenient to observe, take and load after unloading.

[0029] Further, the surface of the inverted bottom plate 14 is provided with a flexible pad 15, which can be a silica gel pad or a foam pad, and the thickness is preferably -mm, which is used to provide buffer protection when the PCB board falls on the inverted bottom plate 14, to avoid scratching or damaging the surface of the PCB board.

[0030] The above examples are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also considered to fall within the protection scope of the present application.
