Description

Technical Field

[0001] This utility model relates to the technical field of PCB board production equipment, specifically to a PCB board mounting and feeding cart. Background Technology

[0002] A PCB, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. The main function of a PCB is to miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and the optimization of appliance layout. Various electronic components, such as resistors, capacitors, inductors, diodes, transistors, and integrated circuits, can be mounted on a PCB to achieve specific circuit functions.

[0003] Before the surface mount technology (SMT) process, PCBs have numerous connecting wires and solder pads for soldering electronic components. During transport, existing PCB loading trolleys may experience friction between PCBs, causing scratches on the connecting wires and solder pads. This affects the performance and reliability of the PCBs. Furthermore, existing PCB loading trolleys typically use single-layer storage racks for easy loading and unloading, resulting in low transport efficiency. Therefore, we propose a new PCB loading trolley to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a PCB board mounting and loading cart to solve the problems mentioned in the background art. Before the mounting process, there are many connecting wires and solder pads for electronic components on the PCB board. During the transportation process, the PCB boards may rub against each other, causing scratches on the connecting wires and solder pads, which will affect the performance and reliability of the PCB board. In addition, the existing PCB board mounting and loading carts usually use a single-layer storage rack for easy loading and unloading of PCB boards, resulting in low transportation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PCB board mounting and loading cart includes a base, with multiple omnidirectional wheels evenly spaced at the bottom of the base and a placement rack at the top of the base. Multiple guide rods are symmetrically arranged on both sides of the inner ends of the placement rack. Two V-shaped lifting plates are spaced apart on the multiple guide rods. Two electric push rods are symmetrically arranged at both ends of the bottom of the two V-shaped lifting plates. Multiple conical rubber rods are symmetrically and evenly spaced on both sides of the bottom of the V-shaped lifting plates.

[0007] The width of the tapered rubber rod at the end near the V-shaped lifting plate is smaller than the width at the end away from the V-shaped lifting plate.

[0008] Furthermore, the base includes a mounting base plate, and a push handle is provided at one end of the top of the mounting base plate, the push handle being fixedly connected to the mounting base plate.

[0009] Furthermore, the plurality of the casters are fixedly connected to the bottom of the mounting base plate, and the placement rack is fixedly connected to the top of the mounting base plate.

[0010] Furthermore, the multiple guide rods are fixedly connected to the placement frame.

[0011] Furthermore, the V-shaped lifting plate includes a V-shaped placement plate, with two sliding plates symmetrically arranged at both ends of the V-shaped placement plate. Multiple placement slots are symmetrically and evenly spaced on both sides of the V-shaped placement plate. The two sliding plates are fixedly connected to both ends of the V-shaped placement plate, and the two ends of the sliding plates are slidably connected to two guide rods. The bottom of the sliding plate is fixedly connected to the top of the electric push rod.

[0012] Furthermore, the bottom of the electric push rod at the bottom of the upper V-shaped lifting plate is fixedly connected to the top of the lower V-shaped lifting plate, and the bottom of the electric push rod at the bottom of the lower V-shaped lifting plate is fixedly connected to the mounting base plate. Multiple conical rubber rods are fixedly connected to the bottom of the V-shaped placement plate on both sides of the placement groove, and the conical rubber rods are set perpendicular to the placement groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a V-shaped lifting plate with multiple tapered rubber rods symmetrically and evenly spaced on both sides of its bottom. The width of each tapered rubber rod near the V-shaped lifting plate is smaller than the width of the rod away from it. During this process, when a PCB board is placed on the V-shaped lifting plate, the tapered rubber rods on both sides of the bottom of the plate can clamp the bottom of PCB boards of different sizes and separate adjacent PCB boards, preventing scratches.

[0015] 2. This utility model features a base with a placement rack on top. Multiple guide rods are symmetrically arranged on both sides of the placement rack's interior. Two V-shaped lifting plates are spaced apart on each guide rod, and two electric push rods are symmetrically arranged at the bottom ends of the two V-shaped lifting plates. By using two V-shaped lifting plates, the number of PCBs that can be transported can be increased, and loading and unloading of PCBs is easier. Simultaneously, by using the electric push rods to push the V-shaped lifting plates along the guide rods, the space between the upper and lower V-shaped lifting plates can be adjusted for loading and unloading PCBs, facilitating the process.

[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] Please see Figures 1-4 This utility model provides a technical solution: a PCB board mounting and loading cart, including a base 1, a plurality of universal wheels 2 evenly spaced at the bottom of the base 1, a placement rack 3 at the top of the base 1, a plurality of guide rods 4 symmetrically arranged on both sides of the inner ends of the placement rack 3, two V-shaped lifting plates 5 spaced apart on the plurality of guide rods 4, two electric push rods 6 symmetrically arranged at the bottom ends of the two V-shaped lifting plates 5, and a plurality of conical rubber rods 7 symmetrically and evenly spaced on both sides of the bottom of the V-shaped lifting plates 5;

[0023] The width of the tapered rubber rod 7 at the end near the V-shaped lifting plate 5 is smaller than the width at the end away from the V-shaped lifting plate 5.

[0024] The base 1 includes a mounting base plate 101, and a push handle 102 is provided at one end of the top of the mounting base plate 101. The push handle 102 is fixedly connected to the mounting base plate 101. In this example, by providing the push handle 102, it is easy to drag the multiple casters 2 at the bottom of the mounting base plate 101 to roll and transport the PCB board to the designated position.

[0025] Multiple casters 2 are fixedly connected to the bottom of the mounting base 101, and the placement rack 3 is fixedly connected to the top of the mounting base 101.

[0026] Multiple guide rods 4 are fixedly connected to the placement frame 3. In this example, by setting multiple guide rods 4, the V-shaped lifting plate 5 can be raised and lowered smoothly, improving the stability of the equipment.

[0027] The V-shaped lifting plate 5 includes a V-shaped placement plate 501. Two sliding plates 502 are symmetrically arranged at both ends of the V-shaped placement plate 501. Multiple placement slots 503 are symmetrically and evenly spaced on both sides of the V-shaped placement plate 501. The two sliding plates 502 are fixedly connected to both ends of the V-shaped placement plate 501, and both ends of the sliding plates 502 are slidably connected to two guide rods 4. The bottom of the sliding plates 502 is fixedly connected to the top of the electric push rod 6. In this example, by setting the V-shaped placement plate 501, the number of PCB boards that can be transported can be increased. At the same time, the outward tilt facilitates the loading and unloading of PCB boards.

[0028] The bottom of the electric push rod 6 at the bottom of the upper V-shaped lifting plate 5 is fixedly connected to the top of the lower V-shaped lifting plate 5. The bottom of the electric push rod 6 at the bottom of the lower V-shaped lifting plate 5 is fixedly connected to the mounting base plate 101. Multiple tapered rubber rods 7 are fixedly connected to the bottom of the V-shaped placement plate 501 on both sides of the placement groove 503, and the tapered rubber rods 7 are set perpendicular to the placement groove 503. In this example, by setting the electric push rods 6, it is easy to push the V-shaped lifting plate 5 and adjust the distance between the V-shaped lifting plates 5, which facilitates the loading and unloading of PCB boards.

[0029] Working principle: By pushing the handle 102, the multiple casters 2 at the bottom of the mounting base 1 are pushed to the designated position. The electric push rod 6 pushes the sliding plate 502 up and down along the guide rod 4, thereby adjusting the distance between the upper and lower V-shaped placement plates 501. The PCB board is loaded and inserted into the placement slot 503. The PCB board slides between the tapered rubber rods 7 on both sides of the bottom of the V-shaped placement plate 501, thereby locking and fixing it. After loading is completed, the electric push rod 6 retracts for easy transportation.
