Description

Technical Field

[0001] The utility model relates to the technical field of carriers, in particular to a carrier for PCB boards. Background Art

[0002] During the production process of PCB boards, PCB boards that are to be processed or have been processed need to be stored in preparation for the production of the next process. Patent No. CN201320788886.1 discloses a PCB board placement box, including a PCB board placement rack and a PCB board placement box assembly. The PCB board placement rack includes a support plate and two clamping plates arranged on the support plate. The support plate is provided with a bottom leg below. Two symmetrical slide grooves are provided on the support plate. The clamping plates are slidably installed on the slide grooves by sliders provided on the bottom of the clamping plates and cooperating with the slide grooves. The two clamping plates are provided with a slot for clamping the PCB board between the two clamping plates on the opposite sides. The PCB board placement box assembly includes a shell for placing the PCB board placement rack, which is composed of a bottom plate, two side plates welded to the bottom plate, and a top plate welded to the two side plates. When removing the PCB board, the blocking rod 4 can be removed and the PCB board can be pulled out from the clamping plate 3-1. Since the PCB board and the clamping plate are in surface-to-surface contact, the surface of the PCB board may be scratched and worn during the process of extracting the PCB board. When removing the material, the blocking rod needs to be completely detached, which may easily lead to the loss of the blocking rod. Therefore, the utility model provides a carrier for PCB boards. Utility Model Content

[0008] Preferably, a plurality of supporting rods perpendicular to the panel surface are provided on the inner side of the rear panel along its vertical midline.

[0009] The beneficial effects of the technical solution of this utility model are:

[0010] The slots provided on the inner sides of the two side panels and the support rods provided on the rear panel provide support for the PCB, which can reduce the contact area between the PCB and the carrier. Only three inactive areas on the printed surface of the PCB come into contact with the jig, preventing wear on the printed surface during placement and removal.

[0011] The L-shaped plate is connected to the side plate by fastening bolts and can slide down the mountain. The L-shaped plate is provided with an avoidance notch matching the slot. The slot can be opened and closed by adjusting the position of the L-shaped plate. The PCB board can be accessed without removing the entire L-shaped plate. The operation is convenient and not easy to lose. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] Example:

[0018] like Figure 1 and Figure 2As shown, the utility model is a carrier for PCB boards, including a placement box and a placement rack arranged on the inner side thereof, the placement box includes a frame 1, a bottom plate 2 welded to the bottom of the frame 1, two side panels 3 welded to the bottom plate 2 and a rear panel 4 welded to the rear sides of the two side panels 3, the front of the side panels 3 is provided on the blocking member, and it is characterized in that: the placement rack includes a plurality of connecting blocks 5 connected to the inner walls of the two side panels 3, and slots 6 are provided on the opposite surfaces of the connecting blocks 5 on both sides, and the blocking member can be slidably connected to the side panels 3.

[0019] The blocking member includes an L-shaped plate 7, one side of the L-shaped plate 7 is close to the side surface of the side panel 3, and the other half extends to the front of the slot 6. The front of the L-shaped plate 7 is provided with a plurality of avoidance notches 8, and a baffle is formed between two of the notches 8. The L-shaped plate 7 is connected to the side panel 3 by fasteners.

[0020] The fastener includes a plurality of vertical slots 9 provided on the side of the L-shaped plate 7. The L-shaped plate 7 is connected to the side plate 3 by fastening bolts 10 passing through the slots 9. One end of a spring 11 is connected to the top of the side of the L-shaped plate 7, and the other end of the spring 11 is connected to the top of the frame 1.

[0021] A shift rod 12 is connected to the side surface of the L-shaped plate 7 , and one end of the spring 11 is connected to the shift rod 12 .

[0022] The inner side of the rear panel 4 is provided with a plurality of supporting rods 13 perpendicular to the panel surface along its vertical midline.

[0023] The working process of the utility model is as follows: when the carrier is in an unloaded state, the avoidance gap 8 is aligned with the slot 6, and the spring 11 is in a stretched state. When loading the PCB board, the PCB board is inserted into the slot 6 in sequence by an automatic loader or a manipulator. After loading is completed, the fastening bolts 10 are loosened, and the L-shaped plate 7 moves upward under the pulling force of the spring 11. The part between the two notches 8 blocks the end of the slot 6, thereby preventing the PCB board from sliding out. The fastening bolts 10 are tightened to fix the L-shaped plate 7 to the side plate 3; when the PCB board needs to be taken out, the fastening bolts 10 are loosened, the lever 12 is pushed downward to align the notch 8 with the slot 6, and then the fastening bolts 10 are tightened to facilitate the removal of the PCB board.

[0024] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
