Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a placement tray for batch inspection of circuit boards. Background Technology

[0002] Inspection is a crucial part of the circuit board (PCB) production process. Before inspection, batches of PCBs are arranged into appropriate trays for rapid testing. However, existing PCB support trays often have fixed dimensions for each positioning support area, limiting their applicability to specific PCB sizes and models. This makes them unsuitable for diverse applications. Therefore, there is an urgent need to develop a more versatile PCB batch inspection tray that is easily adjustable, can support PCBs of different sizes and models, and has broader applicability. This would overcome the current shortcomings and meet broader requirements. Utility Model Content

[0003] The purpose of this invention is to provide a tray for batch inspection of circuit boards, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tray for batch inspection of circuit boards includes a housing, movable frames, a forward and backward adjustment mechanism, a fixed frame, and a positioning support mechanism. Multiple movable and fixed frames are provided. The movable frames are movably mounted within the housing, and the fixed frames are fixedly mounted within the housing. Each movable frame faces one fixed frame. Multiple positioning support mechanisms are installed on both the movable and fixed frames. The cooperation of these positioning support mechanisms on the movable and fixed frames supports the circuit boards. The positions of the positioning support mechanisms on the movable and fixed frames can be adjusted laterally. A forward and backward adjustment mechanism for moving the multiple movable frames forward and backward is installed within the housing.

[0006] Preferably, the positioning support mechanism includes: a round rod, a baffle, an external thread, a nut, a positioning block, and a positioning groove. The baffle is fixed to the rear end of the round rod, and the external thread is provided at the front end of the round rod. A nut is installed on the outer side of the external thread. The round rod is fixed to the positioning block. Positioning grooves are provided at the four apex corners of the top of the positioning block. A first sliding groove for moving the round rod is provided on the movable frame. A second sliding groove for moving the positioning block is provided on the movable frame. A third sliding groove for moving the round rod is provided on the fixed frame. A fourth sliding groove for moving the positioning block is provided on the fixed frame.

[0007] Preferably, the outer side of the positioning block is coated with an antistatic coating.

[0008] Preferably, the bottom of the fixing frame is fixed with a support plate that is fixed to the outer shell.

[0009] Preferably, the forward and backward movement adjustment mechanism includes a threaded rod, a threaded sleeve, a sliding sleeve, and a guide rod. The threaded rod is rotatably connected to the outer casing, and the guide rod is fixedly installed in the outer casing. Multiple threaded sleeves are installed on the threaded rod, and multiple sliding sleeves are slidably installed on the guide rod. The right end of each movable frame is fixed to a threaded sleeve, and the left end of each movable frame is fixed to a sliding sleeve.

[0010] Preferably, the front end of the threaded rod is fixed with a rotating handle, which is located on the outside of the outer casing.

[0011] The beneficial effects of this utility model are as follows: This tray for batch inspection of circuit boards allows the circuit board to be positioned by placing its four corners into the positioning slots on four different positioning blocks, thus providing positioning support for subsequent testing. Furthermore, tightening the nut secures it against the movable or fixed frame, generating significant friction that prevents the round rod and positioning blocks from sliding. Loosening the nut allows the round rod and positioning blocks to slide, adjusting the lateral distance between the multiple positioning support mechanisms to support circuit boards of different widths. Manual rotation of the handle rotates the threaded rod, which in turn moves the threaded sleeve back and forth, which in turn moves the movable frame back and forth, adjusting the distance between the positioning support mechanisms on the movable and fixed frames to support circuit boards of different lengths and sizes. In summary, this utility model is easy to adjust, can support circuit boards of different sizes, and has wider applicability. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] See Figures 1-6 In this embodiment of the utility model, the placement tray for batch inspection of circuit boards includes a housing 1, a movable frame 2, a front-to-back adjustment mechanism 3, a fixed frame 4, and a positioning support mechanism 5. There are multiple movable frames 2 and multiple fixed frames 4. The movable frame 2 is movably disposed within the housing 1, and the fixed frame 4 is fixedly disposed within the housing 1. A support plate 403 fixed to the bottom of the fixed frame 4 and attached to the housing 1 is fixed thereto. Each movable frame 2 faces one fixed frame 4. Multiple positioning support mechanisms 5 are installed on both the movable frame 2 and the fixed frame 4. The positioning support mechanisms 5 work together to support the circuit board. The position of the positioning support mechanism 5 on the movable frame 2 and the fixed frame 4 can be adjusted laterally to support circuit boards of different widths. The outer shell 1 is equipped with a forward and backward movement adjustment mechanism 3 for driving multiple movable frames 2 to move back and forth. In use, the circuit board is positioned and supported by multiple positioning support mechanisms 5. The forward and backward movement adjustment mechanism 3 drives the movable frame 2 to move back and forth, thereby adjusting the forward and backward distance between the positioning support mechanisms 5 on the movable frame 2 and the fixed frame 4 to position and support circuit boards of different lengths.

[0023] The forward and backward movement adjustment mechanism 3 includes: a threaded rod 301, a threaded sleeve 302, a sliding sleeve 303, and a guide rod 304. The threaded rod 301 is rotatably connected to the outer shell 1, and the guide rod 304 is fixedly installed inside the outer shell 1. Multiple threaded sleeves 302 are installed on the threaded rod 301, and multiple sliding sleeves 303 are slidably installed on the guide rod 304. The right end of each movable frame 2 is fixed to a threaded sleeve 302, and the left end of each movable frame 2 is fixed to a sliding sleeve 303. A rotating handle 3011 is fixed to the front end of the threaded rod 301. The rotating handle 3011 is located on the outside of the outer shell 1. In use, a person rotates the rotating handle 3011 by hand to drive the threaded rod 301 to rotate. The rotation of the threaded rod 301 drives the threaded sleeves 302 to move forward and backward, and the threaded sleeves 302 drive the movable frame 2 to move forward and backward.

[0024] The positioning support mechanism 5 includes: a round rod 501, a baffle 502, an external thread 503, a nut 504, a positioning block 505, and a positioning groove 506. The baffle 502 is fixed to the rear end of the round rod 501, and the external thread 503 is provided at the front end of the round rod 501. A nut 504 is installed on the outer side of the external thread 503. The round rod 501 is fixed to the positioning block 505. Positioning grooves 506 are provided at the four top corners of the positioning block 505, and the positioning grooves 506 are used to support the top corners of the circuit board. The outer side of the positioning block 505 is coated with an anti-static coating to prevent static electricity from being generated when the positioning block 505 contacts the circuit board. The movable frame 2 is provided with a first sliding groove 201 for the movement of the round rod 501, and a second sliding groove 202 for the movement of the positioning block 505. The fixed frame 4 is provided with a useful... The third slide groove 401 on which the round rod 501 moves, and the fourth slide groove 402 on the fixed frame 4 for the movement of the positioning block 505, the round rod 501 passes through the first slide groove 201 or the third slide groove 401, the baffle 502 is located on the rear side of the first slide groove 201 or the third slide groove 401, the nut 504 is located on the front side of the first slide groove 201 or the third slide groove 401, and the positioning block 505 passes through the second slide groove 202 or the fourth slide groove 402. When the nut 504 is tightened, it is pressed against the movable frame 2 or the fixed frame 4, and a large frictional force is generated between the nut 504 and the movable frame 2 or the fixed frame 4, so that the round rod 501 and the positioning block 505 cannot slide. After the nut 504 is loosened, the round rod 501 and the positioning block 505 can slide, thereby adjusting the lateral distance between the multiple positioning support mechanisms 5 so as to provide positioning support for circuit boards of different widths.

[0025] Working principle: This tray for batch inspection of circuit boards is used by placing the four corners of the circuit board into the positioning slots 506 on four different positioning blocks 505, thereby positioning and supporting the circuit board for subsequent testing. When the nut 504 is tightened, it presses against the movable frame 2 or fixed frame 4, generating significant friction between the nut 504 and the movable frame 2 or fixed frame 4, preventing the round rod 501 and positioning blocks 505 from sliding. Loosening the nut 504 allows the round rod 501 and positioning blocks 505 to slide, adjusting the lateral distance between the multiple positioning support mechanisms 5 to provide positioning support for circuit boards of different widths. Manually rotating the handle 3011 rotates the threaded rod 301, which in turn moves the threaded sleeve 302 back and forth, which in turn moves the movable frame 2 back and forth, adjusting the distance between the positioning support mechanisms 5 on the movable frame 2 and fixed frame 4 to provide positioning support for circuit boards of different lengths and sizes.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
