In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0036] In the production process of a circuit board, some equipment requires an automatic board loading and unloading machine. However, manual board handling is still needed for the transfer of the circuit board between different processing equipment of the circuit board, or manual board handling is required when unloading the board after automatic board collection. During the process of manual board handling and placing, there is an easy risk of product scratching, resulting in the generation of defective products, which is not conducive to production.

[0037] For this reason, as Figures 1 to 3As shown, a circuit board storage and transportation device proposed by the utility model includes a frame 100, a moving wheel 110 arranged at the bottom of the frame 100, a telescopic rod group 200 installed on the frame 100 and telescopically arranged on the frame 100 along the vertical direction, a receiving component 300 installed on the top of the telescopic rod group 200, a handle frame 400 rotatably installed on the front end of the frame 100, and a transmission connecting rod group 500 respectively connected to the telescopic rod group 200 and the handle frame 400. Specifically, the moving wheels 110 enable the frame 100 to be easily moved on the ground. The worker holds the handle frame 400 and pushes the frame 100 to the bottom of the circuit board that needs to be transported. Then, the handle frame 400 is rotated toward the end away from the center of the frame 100. Through the transmission connecting rod group 500, the telescopic rod group 200 is driven to extend upward, and the receiving component 300 and the top of the telescopic rod group 200 are lifted upward together. The receiving component 300 receives the circuit board and lifts it upward. Then, the frame 100 is manually pulled outward to transport the circuit board to the target area.

[0038] It should be noted that the frame 100 can move on the ground through the moving wheels 110, and when the handle frame 400 is pulled outward, the telescopic rod group 200 can be driven to extend upward through the transmission connecting rod group 500, so that the receiving assembly 300 is synchronously lifted upward to receive the circuit board coming out of the board placing machine or the stacked circuit board, and then, the frame 100 is manually pulled to transfer the circuit board to the next workstation, thereby avoiding direct manual contact and handling of the circuit board, and conveniently realizing the transportation of the circuit board, avoiding the risk of human-caused scratches on the circuit board surface, and is suitable for application in production and transportation.

[0039] The frame 100 is a rectangular frame, and the four corners of the bottom of the frame 100 are respectively provided with moving wheels 110, so that the frame 100 moves more stably. In addition, the frame 100 includes a front bottom bar 120, and the handle frame 400 is provided with a matching bottom bar 410, which is rotatably installed inside the front bottom bar 120, and the front bottom bar 120 is provided with a threaded hole 1201, and the threaded hole 1201 is screwed with a twisting stud 130, and the twisting stud 130 is suitable for extending into the interior of the front bottom bar 120 to press and fix the matching bottom bar 410. Furthermore, in addition to pulling the handle frame 400 when it is in a rotatable state, the user can lock the handle frame 400 by twisting the stud 130 before pulling, so that the handle frame 400 is in a non-rotatable state to pull the frame 100, thereby improving the safety of the transportation of circuit boards during transit. It is easy to understand that the handle frame 400 rotates toward the side away from the center of the frame 100 to receive the circuit board, and after the frame 100 is pulled out of the original position of supporting the circuit board, the user can rotate the handle frame 400 toward the side of the center of the frame 100 to reset it, and then the telescopic rod group 200 telescopes downward to drive the receiving assembly 300 to move downward. At this time, the handle frame 400 is locked according to the needs of the operation. It is easy to understand that placing the circuit board to be transported at a lower height during transportation can improve the safety and stability during transportation and meet the operating specifications. It should be noted that the front end of the frame 100 generally refers to the end where the user stands relative to the frame 100 when the user holds the handle frame 400. Further, the front bottom rod 120 is provided with a limiting groove 1202, and the limiting groove 1202 includes a first limiting wall 12021 and a second limiting wall 12022. The handle frame 400 rotates between the first limiting wall 12021 and the second limiting wall 12022, and the range of rotation of the handle frame 400 can be limited, and the overall use is more convenient. For example, when the handle frame 400 abuts against the first limiting wall 12021, the handle frame 400 is in a vertical position. Optionally, when the width of the handle frame 400 is set to be small, the handle frame 400 can prevent the circuit board located on the receiving assembly 300 from sliding out from the front end of the frame 100.

[0040] like Figures 1 to 3 As shown, the telescopic rod group 200 includes a first rotating rod 210 and a second rotating rod 220 arranged crosswise, the middle part of the first rotating rod 210 is hinged to the middle part of the second rotating rod 220, the upper and lower ends of the first rotating rod 210 are respectively hinged to the receiving assembly 300 and the frame 100, and the upper and lower ends of the second rotating rod 220 are respectively connected to the receiving assembly 300 and the frame 100 in horizontal sliding connection. The common scissor-type connection structure can be referred to. The drawings of this application are only for illustration. A single set of scissor-type structures is used to drive the receiving assembly 300 installed on the top of the telescopic rod group 200, and the structure is simple and compact. In addition, there are two groups of telescopic rod groups 200, and the two groups of telescopic rod groups 200 are respectively connected to the two sides of the receiving assembly 300, which can drive the receiving assembly 300 to rise and fall more smoothly.

[0041] Furthermore, the transmission link group 500 includes a first transmission rod 510 and a second transmission rod 520, the opposite ends of the first transmission rod 510 and the second transmission rod 520 are hinged by a rotating pin, and the opposite ends are respectively hinged to the handle frame 400 and the frame 100, and the first rotating rod 210 is provided with a transmission groove 2101, which extends along the length direction of the first rotating rod 210, and the rotating pin is slidably arranged in the transmission groove 2101. The transmission link group 500 adopts a connecting rod structure, with the handle frame 400 as a driving source, driving the telescopic rod group 200 to telescope and extend, and the structure is simple and compact, so that the handle frame 400 can not only pull the frame 100 to move, but also control the telescopic movement of the telescopic rod group 200 in a linkage manner, and the design is more ingenious.

[0042] Refer to Figures 1 to 3, in some embodiments of the present utility model, the receiving assembly 300 includes a receiving fork 310 and a roller 320. The roller 320 is rotatably installed in the middle of the receiving fork 310. The upper end of the roller 320 protrudes upward from the upper end surface of the receiving fork 310 to support the circuit board and rollingly cooperate with the bottom surface of the circuit board. In this regard, the receiving fork 310 can be conveniently inserted under the circuit board, and the roller 320 can better support the circuit board. Moreover, the circuit board can roll on the roller 320 and is not easily scratched. Optionally, the roller 320 is made of a material with a relatively low hardness, such as plastic or rubber. In addition, the lower end of the roller 320 protrudes downward from the lower end surface of the receiving fork 310. A fixing plate 340 is arranged below the receiving fork 310. Among them, the fixing plate 340 is relatively fixed to the receiving fork 310. For example, the fixing plate 340 is fixedly connected to the receiving fork 310, and the upper end surface of the fixing plate 340 is located below the lower end surface of the receiving fork 310. A friction plate 330 is adapted to be inserted between the receiving fork 310 and the fixing plate 340. The friction plate 330 is adapted to press against the bottom end of the roller 320 to stop the roller 320. Furthermore, the circuit board can be placed more stably on the upper end of the roller 320, reducing the risk of the circuit board slipping out. Optionally, the friction plate 330 is a rubber plate, and after being inserted, both end faces are respectively pressed and fixed to the roller 320 and the fixing plate 340. Further, the receiving assembly 300 includes a first limiting plate 350 and a second limiting plate 360. The first limiting plate 350 and the second limiting plate 360 are arranged opposite to each other on both sides of the receiving fork 310 to limit the lateral movement of the circuit board and improve the safety during transportation. In addition, the first limiting plate 350 is provided with a first adjustment groove 3501, and the first adjustment groove 3501 is adapted to adjust the distance between the first limiting plate 350 and the second limiting plate 360. The second limiting plate 360 is provided with a second adjustment groove, and the second adjustment groove is adapted to adjust the distance between the second limiting plate 360 and the first limiting plate 350. Optionally, the receiving fork 310 is provided with a first threaded fixing hole corresponding to the first adjustment groove 3501 and a second threaded fixing hole corresponding to the second adjustment groove. The first limiting plate 350 is fixed by a first screw located in the first adjustment groove 3501 and the first threaded fixing hole, and the second limiting plate 360 is fixed by a second screw located in the second adjustment groove and the second threaded fixing hole.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field to which it belongs, various changes can be made without departing from the purpose of the present utility model.
