Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a placing and conveying rack for PCB circuit board plug-in components. Background Art

[0002] A printed circuit board (PCB), as a basic electronic component, is a carrier for supporting electronic components and electrical connection. Almost every electronic device that has electronic components such as integrated circuits needs to use a printed circuit board.

[0003] The manufacturing process of a printed circuit board involves manual plug-in, that is, inserting the components processed by chip mounting into the corresponding positions of the PCB to prepare for wave soldering.

[0004] The existing manual plug-in is completed by workers on a traditional manual workbench. First, the components to be inserted are classified and placed in a placement box. When performing the plug-in work, the components are taken out from the placement box and then inserted into the circuit board. Thus, the placement boxes for placing components are placed randomly without a fixing device for fixing them, which is prone to accidental touch and dropping, and it is not convenient to transport the placement boxes.

[0022] The following specific implementation content provides various different embodiments or examples for implementing the present utility model. Of course, these are only embodiments or examples and are not intended to be restrictive. In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0023] Such as Figures 1 - 3A placement conveyor rack for PCB circuit board plug-ins, as shown, includes a frame body 1. There are rectangular frames 2 spaced vertically above and below the frame body 1. A conveying roller shaft 3 is installed in the rectangular frame 2. An n-shaped frame 4 is clamped at the front end of the rectangular frame 2. A hook 5 is provided on the n-shaped frame 4, and the hook 5 is used to hang a placement box 6 for placing plug-ins.

[0024] In the present utility model, the placement box 6 can be hung in the hook 5, so as to fix the placement box 6, avoid accidental touching and dropping, and improve the stability and safety during production.

[0025] In addition, a conveying roller shaft 3 is provided on the rectangular frame 2, so that it is convenient for the operator to convey the placement box 6 from the previous station to the hook 5 through the conveying roller shaft 3, improving the usability and flexibility during production.

[0026] At the same time, multiple placement boxes 6 can be hung on the frame body 1, which is convenient for management and transportation.

[0027] See Figure 1 As shown, the frame body 1 includes a bottom frame 21. Side frames 22 are spaced left and right on the bottom frame 21. The rectangular frame 2 is arranged between the two side frames 22; the side frames 22 are fixed to the bottom frame 21 by welding.

[0028] See Figure 1 、 Figure 2 As shown, the two rectangular frames 2 are both inclined. Among them, rotating shafts 31 are arranged on both sides of the rear end of the rectangular frame 2. The rotating shafts 31 are rotatably installed between the two side frames 22. T-shaped chutes 32 are arranged along the length direction on both sides of the front end of the rectangular frame 2. Bolts 33 slide in the T-shaped chutes 32. Vertical chutes 34 are arranged on the side frames 22. The screw heads of the bolts 33 slide in the T-shaped chutes 32, and the threaded sections of the bolts 33 slide in the vertical chutes 34 and are threadedly connected with fixing nuts 35.

[0029] When installing the rectangular frame 2, first rotatably install the rotating shafts 31 on the side frames 22, and then slide the bolts 33 in the T-shaped chutes 32 and the vertical chutes 34 to adjust the inclination angle of the rectangular frame 2. After the adjustment is completed, tighten the fixing nuts 35 to directly place the placement box 6 from the previous station on the conveying roller shaft 3 of the rectangular frame 2. Due to the straight body weight of the placement box 6, it rolls down to the hook 5, facilitating the placement box 6 to be hung in the hook 5.

[0030] Furthermore, in order to prevent the placement box 6 from sliding forward in the conveying roller shaft 3, a limiting plate 41 protruding upward is also provided on the n-shaped frame 4, so as to limit the placement box 6 through the limiting plate 41.

[0031] SeeFigure 2 As shown, the front ends of the two rectangular frames 2 spaced up and down both extend forward. The length of the forward extension of the upper rectangular frame 2 is A, and the length of the forward extension of the lower rectangular frame 2 is B. The length of B is longer than the length of A. Thus, when the worker performs the plug-in work on the workbench 100, the placement box 6 hung above will not obstruct the placement box 6 hung below, facilitating the worker to take out the electronic components from the placement box 6.

[0032] In the present utility model, movable wheels 61 with brakes are provided at the four corners of the bottom frame 21, and a handle 71 is provided at the rear side of the side frame 22. Thus, it is convenient to move the frame body 1.

[0033] See Figure 1 As shown, a stop bar 81 is connected to the lower sides of the two side frames 22. Thus, the bottom frame 21 can be used to place items, and the stop bar 81 can be used to prevent the items from falling, improving the practicability and flexibility of the frame body 1.

[0034] Combined with the accompanying drawings and the above display and description of the basic principles, main features and advantages of the present utility model, those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
