Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing, and in particular to a circuit board production transfer feeding device. Background Technology

[0002] In the production process of printed circuit boards (PCBs), it is often necessary to transfer and load PCB substrates. Currently, the common loading method is to use automated loading equipment, which can greatly improve work efficiency. The loading method involves placing multiple layers of PCBs arranged vertically in a loading box. As the lifting mechanism gradually moves the loading box upward, a pushing mechanism on one side pushes the PCBs to achieve the purpose of automatic loading. However, since the sides of the PCBs are placed in C-shaped slots, the sides of the PCBs will continuously rub against the slots during the gradual movement of the PCBs. This can cause scratches and wear on the ends of the PCBs, resulting in defective boards, which in turn affects subsequent PCB processing. Therefore, to address the above problems, a PCB production transfer and loading device is proposed. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a feeding device for circuit board production, in which the supporting mechanism and the bottom limiting component work together to automatically lift the circuit board to a certain height, so that the two sides of the circuit board do not contact or only slightly contact the inside of the circuit board placement frame, thus ensuring the quality of the circuit board.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a circuit board production transfer feeding device, including a feeding box and casters;

[0005] The bottom of the loading box is equipped with multiple casters for rolling;

[0006] The inner wall of the feeding box is equipped with symmetrically distributed circuit board placement frames, and each of the opposite end faces of the circuit board placement frames is provided with a limiting groove for placing the circuit board.

[0007] The bottom of each circuit board placement frame is equipped with a bottom limiting component, and the inner side of the bottom limiting component is equipped with a support mechanism for supporting the circuit board upward during the circuit board loading process.

[0008] The supporting mechanism includes push plates with both ends set inside the bottom limiting member and slidably connected thereto. A moving rod is fixedly connected to the center of the push plate. A second guide groove is opened on both sides of the moving rod. A second placement groove opened on both sides of the moving rod is also connected to one side of the second guide groove.

[0009] Fixed rods are slidably connected to both sides of the movable rod, and the other end of the fixed rod is fixedly connected to the bottom limiting member.

[0010] During the production of circuit boards, it is often necessary to transfer and load circuit boards. Currently, the common loading method is to use automatic loading equipment, which can greatly improve work efficiency. The loading method involves placing multiple layers of circuit boards distributed vertically in the loading box. As the lifting mechanism gradually moves the loading box upward, the pushing mechanism on one side pushes the boards to achieve the purpose of automatic loading. However, since the sides of the circuit boards are placed in C-shaped grooves, during the gradual movement of the circuit boards, the sides of the circuit boards will continuously rub against the grooves, resulting in scratches and wear on the ends of the circuit boards, leading to defective boards, which in turn affects subsequent circuit board processing steps.

[0011] In the technical solution of this application, by setting bottom limiting components and supporting mechanisms at the bottom of the circuit board placement frames on both sides, when the circuit board is pushed, its supporting mechanism and bottom limiting components cooperate to automatically lift the circuit board to a certain height, so that the two sides of the circuit board do not contact or only slightly contact the inside of the circuit board placement frame. Furthermore, ball bearings are set on the upper surface of the moving rod, which can reduce the wear of the circuit board during loading and ensure the quality of subsequent processing of the circuit board.

[0012] Furthermore, the bottom limiting component includes a limiting frame that is fixedly connected to the circuit board placement frame on the outside. A first guide groove and a first placement groove are provided on one side of the limiting frame, and one end of the first guide groove is connected to the first placement groove.

[0013] One side of the limiting frame is fixedly connected to the supporting mechanism.

[0014] Furthermore, a return spring is fixedly connected to one side of each fixed rod, and the other end of each return spring is fixedly connected to the push plate.

[0015] Furthermore, the upper surface of the moving rod is fitted with evenly distributed balls, and the upper surface of the balls is raised relative to the upper surface of the moving rod.

[0016] Furthermore, the first placement slot is set at an angle.

[0017] Furthermore, the second placement slot is set at an angle.

[0018] When the supporting mechanism is moved by the external pushing mechanism, the two ends of its push plate slide out through the first placement groove and move upward. At the same time, the fixed rods on both sides of the moving rod disengage from the second placement groove inside the moving rod and enter the second guide groove. At this time, the moving rod can be moved upward as a whole, and the circuit board above it can be moved upward. The two sides of the circuit board separate from the inner wall of the circuit board placement frame or make slight contact. During its pushing process, its friction is greatly reduced, ensuring the quality of the circuit board.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. By setting bottom limiting components and supporting mechanisms at the bottom of the circuit board placement frames on both sides, when the circuit board is pushed, its supporting mechanism and bottom limiting components cooperate to automatically lift the circuit board to a certain height, so that the sides of the circuit board do not contact or only slightly contact the inside of the circuit board placement frame. Furthermore, ball bearings are set on the upper surface of the moving rod, which can prevent scratches and wear on the circuit board during loading, and ensure the quality of subsequent processing of the circuit board.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] like Figure 1-4 As shown, a circuit board production transfer feeding device includes a feeding box 1 and casters 2;

[0029] The bottom of the feeding box 1 is equipped with multiple casters 2 for movement;

[0030] The inner wall of the feeding box 1 is equipped with symmetrically distributed circuit board placement frames 3, and each of the opposite end faces of the circuit board placement frames 3 is provided with a limiting groove 4 for placing the circuit board.

[0031] The bottom of each circuit board placement frame 3 is equipped with a bottom limiting component 5, and the inner side of the bottom limiting component 5 is equipped with a supporting mechanism 6 for supporting the circuit board upward during the circuit board loading process.

[0032] The supporting mechanism 6 includes a push plate 601 with both ends set inside the bottom limiting member 5 and slidably connected thereto. A moving rod 602 is fixedly connected to the center of the push plate 601. A second guide groove 603 is opened on both sides of the moving rod 602. A second placement groove 604 opened on both sides of the moving rod 602 is also connected to one side of the second guide groove 603.

[0033] Fixed rods 605 are slidably connected to both sides of the movable rod 602, and the other end of the fixed rod 605 is fixedly connected to the bottom limiting member 5.

[0034] During the production of circuit boards, it is often necessary to transfer and load circuit boards. Currently, the common loading method is to use automatic loading equipment, which can greatly improve work efficiency. The loading method involves placing multiple layers of circuit boards distributed vertically in the loading box. As the lifting mechanism gradually moves the loading box upward, the pushing mechanism on one side pushes the boards to achieve the purpose of automatic loading. However, since the sides of the circuit boards are placed in C-shaped grooves, during the gradual movement of the circuit boards, the sides of the circuit boards will continuously rub against the grooves, resulting in scratches and wear on the ends of the circuit boards, leading to defective boards, which in turn affects subsequent circuit board processing.

[0035] In the technical solution of this application, by providing bottom limiting members 5 and supporting mechanisms 6 at the bottom of the circuit board placement frame 3 on both sides, when the circuit board is pushed, the supporting mechanism 6 and the bottom limiting members 5 cooperate to automatically lift the circuit board to a certain height, so that the two sides of the circuit board do not contact or only slightly contact the inside of the circuit board placement frame 3. Furthermore, a ball bearing 607 is provided on the upper surface of the moving rod 602, which can reduce the wear of the circuit board during loading and ensure the quality of subsequent processing of the circuit board.

[0036] The bottom limiting member 5 includes a limiting frame 501 that is fixedly connected to the circuit board placement frame 3 on the outside. A first guide groove 502 and a first placement groove 503 are provided on one side of the limiting frame 501. One end of the first guide groove 502 is connected to the first placement groove 503.

[0037] One side of the limiting frame 501 is fixedly connected to the supporting mechanism 6.

[0038] The first placement slot 503 is set at an angle.

[0039] Each side of the fixed rod 605 is fixedly connected with a return spring 606, and the other end of the return spring 606 is fixedly connected to the push plate 601.

[0040] The upper surface of the moving rod 602 is equipped with evenly distributed balls 607, and the upper surface of the balls 607 is raised relative to the upper surface of the moving rod 602.

[0041] The second placement slot 604 is set at an angle.

[0042] When the supporting mechanism 6 is moved by the external pushing mechanism, the two ends of its push plate 601 slide out through the first placement groove 503 and move upward. At the same time, the fixed rods 605 on both sides of the moving rod 602 disengage from the second placement groove 604 inside the moving rod 602 and enter the second guide groove 603. At this time, the moving rod 602 can be moved upward as a whole, and the circuit board above it can be moved upward. The two sides of the circuit board separate from or slightly contact the inner wall of the circuit board placement frame 3. During its pushing process, its friction is greatly reduced, ensuring the quality of the circuit board.

[0043] Both the first placement groove 503 and the second placement groove 604 are inclined. When the circuit board is being loaded, the push plate 601 and the fixing rod 605 are guided into the first guide groove 502 and the second guide groove 603 respectively by the action of the first placement groove 503 and the second placement groove 604, so as to realize the upward movement of the moving rod 602, which can support the circuit board and ensure that the two sides of the circuit board are not damaged by friction with the inner wall of the circuit board placement frame 3 when the circuit board is being loaded. The moving rod 602 is provided with a ball bearing 607. When the circuit board is guided into the conveying mechanism, the ball bearing 607 changes the friction between the moving rod 602 and the circuit board to rolling friction, which greatly reduces the friction and ensures the quality of the circuit board.

[0044] After the circuit board is loaded, the reset spring 606 can push the push plate 601 back into the second placement slot 604, which is convenient for the equipment to be used repeatedly. The reset spring 606 has bending properties, which can ensure that the push plate 601 is back into the second placement slot 604.

[0045] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
