Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing technology, specifically to a board feeding mechanism and PCB board separating equipment. Background Technology

[0002] PCB boards are the main carriers for controlling electronic products. The original PCB boards used to load electronic components are generally large-sized board structures, and their size mainly depends on factors such as the supplier and the transfer conditions of the board. Therefore, in the production process, it is often necessary to first cut the large-sized original PCB boards into smaller PCB sub-boards.

[0003] In existing technologies, belt conveyor mechanisms are mainly used to achieve the feeding and discharging of PCB boards, which generally has the following problems:

[0004] 1. The complex structure of belt conveyor mechanisms not only requires a large space in equipment layout, resulting in an increase in the overall size of the equipment, but also makes maintenance more difficult, thus increasing equipment maintenance costs.

[0005] 2. The contact area between the belt conveyor and the PCB board is relatively large. Because the PCB board itself is thin, it tends to stick tightly to the belt surface when placed on it. If the equipment malfunctions and needs to be stopped for maintenance, it often requires manual prying up the edges of the board or pushing it off the belt to unload it, resulting in low efficiency and convenience. This is especially true when conveying large PCB boards, which have considerable weight, making it even more difficult to manually pry up the edges or push the board for unloading. Utility Model Content

[0006] To address the shortcomings of the prior art, this utility model provides a board feeding mechanism that combines a roller-type or ball-bearing feeding conveyor with a belt-type or roller-type discharging conveyor to transport PCB boards before and after slitting. Compared to the prior art, which uniformly uses belt conveyors, this mechanism not only effectively reduces the contact area with the PCB board while transporting it, thus facilitating PCB board unloading, but also has a simple overall structure, effectively reducing the overall size and maintenance difficulty of the mechanism.

[0007] This utility model provides a PCB board separating device, which combines the above-mentioned board feeding mechanism with the separating device body.

[0053] 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. The described embodiments are some, but not all, of the embodiments of this utility model.

[0054] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0055] Example 1:

[0056] Please see the appendix Figure 1 The feeding mechanism 10 of this utility model embodiment includes a feeding conveying assembly 100 disposed at the feeding end of the PCB splitting equipment, and a discharging conveying assembly 200 disposed at the discharging end of the PCB splitting equipment. The feeding conveying assembly 100 is used for feeding and conveying the original PCB board to be split, and is preferably a roller conveying assembly or a ball bearing conveying assembly; the discharging conveying assembly 200 is used for discharging and conveying the split PCB board, and is preferably a belt conveying assembly or a roller conveying assembly.

[0057] The board feeding mechanism 10 of this embodiment is formed by combining a roller-type or ball-type feeding conveyor assembly 100 with a belt-type or roller-type discharging conveyor assembly 200 to transport PCB boards before and after slitting. Compared with the prior art, which uniformly uses belt conveyor, it can not only effectively reduce the contact area with the PCB board while realizing the PCB board transportation, so as to facilitate the unloading of the PCB board, but also has a simple overall structure, which can effectively reduce the overall volume of the mechanism and reduce the difficulty of overall maintenance.

[0058] In particular, the roller-type or ball-bearing type feeding conveyor assembly 100 can effectively solve the problem of manually prying up the edges of the PCB board or pushing the PCB board to achieve unloading when conveying large-sized and heavy PCB boards. Since the size of the PCB board after cutting is small, the belt-type or roller-type discharging conveyor assembly 200 can be used to transport it, which can effectively prevent the PCB board from falling into the gaps of the conveyor assembly.

[0059] Please refer to the appendix for further details. Figure 2In some embodiments, when the feeding conveying assembly 100 is a roller conveying assembly, its specific structure includes a roller mounting frame 110 disposed at the feeding end of the PCB depaneling equipment for mounting and limiting the roller units 120, and multiple sets of roller units 120 arranged side-by-side on the roller mounting frame 110 for rolling conveying of the PCB raw boards to be depaneled. Please refer to the appendix for further details. Figure 3 The roller unit 120 includes multiple roller mounting shafts 121 mounted on a roller mounting bracket 110, multiple rollers 122 spaced apart on the roller mounting shafts 121, and roller limiting sleeves 123 located between two adjacent rollers 122 and fitted onto the roller mounting shafts 121. The roller mounting shafts 121 are used to mount the rollers 122; the rollers 122 are used to achieve rolling conveying of the PCB raw boards to be cut, and the multiple rollers 122 mounted on the multiple roller mounting shafts 121 can form a rolling conveying platform for conveying the PCB raw boards to be cut; the roller limiting sleeves 123 are used to space and limit the rollers 122 to prevent uneven bearing force applied to the PCB raw boards by different parts of the conveying platform due to roller displacement, thereby affecting the accuracy of the PCB raw boards feeding into the PCB depaneling equipment and thus affecting the PCB board cutting quality.

[0060] Preferably, the width of the roller 122 does not exceed 5% of the length of the roller mounting shaft 121; this further reduces the contact area with the PCB board while enabling rolling transport of the PCB, thus facilitating unloading of the PCB board in case of equipment failure. More preferably, the distance between two adjacent rollers 122 is at least 5% of the length of the roller mounting shaft 121; since the PCB boards to be cut are generally large, using rollers 122 with a larger adjacent distance for transport not only effectively reduces the contact area between the rollers 122 and the PCB board, further facilitating unloading of the PCB board in case of equipment failure, but also effectively reduces the production and maintenance costs of the components, thereby effectively reducing the overall production and maintenance costs of the mechanism.

[0061] Please refer to the appendix for further details. Figure 4In some embodiments, when the feeding and conveying assembly 100 is a ball bearing conveying assembly, its specific structure includes a ball bearing mounting plate 130 disposed at the feeding end of the PCB splitting equipment, and a plurality of ball bearing units 140 arranged in a matrix on the ball bearing mounting plate 130. The ball bearing mounting plate 130 is used for limiting and mounting the ball bearing units 140; the ball bearing units 140 are used to realize the rolling conveying of the PCB original boards to be split. Preferably, the interval between two adjacent ball bearing units 140 is at least 10 cm. Since the PCB original boards to be split are generally large, using ball bearing units 140 with a spacing of at least 10 cm for conveying them not only effectively reduces the contact area between the ball bearing units 140 and the PCB original board while realizing the rolling conveying of the PCB original board, thus further facilitating the unloading of the PCB original board in case of equipment failure, but also effectively reduces the production and maintenance costs of the assembly, thereby effectively reducing the overall production and maintenance costs of the mechanism.

[0062] Please refer to the appendix for further details. Figure 5 In some embodiments, when the discharge conveying assembly 200 is a belt conveyor assembly, its specific structure includes a belt mounting frame 210 disposed at the discharge end of the PCB separating equipment, a conveyor belt 220 mounted on the belt mounting frame 210, and a belt drive unit 230 disposed on the belt mounting frame 210. The belt mounting frame 210 is used for mounting the conveyor belt 220 and the belt drive unit 230; the conveyor belt 220 is used for discharging the PCB boards after separation; and the belt drive unit 230 is used to drive the conveyor belt 220 to discharge the PCB boards. The overall structure of the belt conveyor assembly is not the main inventive point of this technical solution, and therefore will not be described in detail here. Alternatively, existing belt assemblies capable of conveying PCB boards can also be used.

[0063] Please refer to the appendix for further details. Figure 6 In some embodiments, when the discharge conveying assembly 200 is a roller conveying assembly, its specific structure includes a roller mounting frame 240 disposed at the discharge end of the PCB separating equipment, and multiple rollers 250 arranged side by side on the roller mounting frame 240 for conveying the PCB boards after separation; and the tops of the multiple rollers 250 are parallel, forming a PCB board conveying platform parallel to the horizontal direction. Furthermore, the outer periphery of the rollers 250 is wrapped with an electrostatic buffer pad to achieve shock absorption and anti-slip conveying of the PCB boards.

[0064] Example 2:

[0065] Please see the appendix Figure 1The PCB board splitting equipment of this utility model includes a splitting equipment body 20 for splitting the original PCB board into PCB boards of a preset size, and a board feeding mechanism 10 of embodiment 1 for realizing the feeding and conveying of the original PCB board to be split and the discharging and conveying of the split PCB board; and the feeding and conveying component 100 is disposed at the feeding end of the splitting equipment body 20, and the discharging and conveying component 200 is disposed at the discharging end of the splitting equipment body 20.

[0066] The PCB board separating equipment in this embodiment is formed by combining the board feeding mechanism 10 of embodiment 1 with the separating equipment body 20. It can not only effectively facilitate the unloading of PCB boards and improve the efficiency and convenience of PCB board unloading, but also the overall size of the equipment is small and easy to maintain.

[0067] As can be seen from the technical solutions of the above embodiments, this utility model provides a board feeding mechanism, which not only effectively facilitates the unloading of PCB boards and improves the efficiency and convenience of PCB board unloading, but also has a small overall size and is easy to maintain. This utility model also provides a PCB board separating device using this board feeding mechanism, which similarly not only effectively facilitates the unloading of PCB boards and improves the efficiency and convenience of PCB board unloading, but also has a small overall size and is easy to maintain.

[0068] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0070] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.
