Description

Technical Field

[0001] The utility model relates to the technical field of transfer tray devices, in particular to a printed circuit board transfer tray. Background Art

[0002] A circuit board can be called a printed circuit board or a printed circuit board. It is generally composed of a substrate (non-conductive material), a wiring layer (a conductive metal layer used to connect circuits, equivalent to a wire), a solder mask, a silk screen printing layer, vias, and pads. Its basic function is to fix and connect devices according to a pre-designed circuit to achieve certain functions, miniaturize and visualize the circuit, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Due to the small and complex parts of the printed circuit board itself, its various upper and lower components cannot withstand strong extrusion, so it needs to be fully protected during transportation to ensure the safety of the printed circuit board itself.

[0003] For example, a circuit board transfer device with publication number CN209634537U includes a base, a traveling wheel arranged at the bottom of the base, a bracket fixedly arranged on the upper part of the base, a material receiving mechanism arranged on one side of the bracket, a handle fixedly arranged on the other side of the bracket and a lifting mechanism arranged on the upper part of the base, the material receiving mechanism includes a support plate, a first material receiving device fixedly arranged on one side of the support plate, a second material receiving device arranged at the lower part of the first material receiving device and fixedly connected to the support plate, a first position plate arranged at the other side of the support plate, a second position plate arranged at the lower part of the first position plate and fixedly connected to the support plate, a limit plate arranged at the lower part of the support plate and a threaded sleeve arranged on the first position plate and the second position plate.

[0004] The above device is provided with a material holder, and the rollers provided in addition can be pushed in and pulled out conveniently, which increases its convenience in transportation. However, due to its relatively simple design, the protective effect on the printed circuit board is reduced. If it is driven on a winding road, it is a heavy test for the printed circuit board. In addition, the device itself lacks the function of fixing the printed circuit board. Due to the wide variety of printed circuit boards, their shapes or structures are more or less different. Different printed circuit boards also require different fixing ends, and the lack of them may cause instability and damage to components. Utility Model Content

[0005] The utility model aims to provide a printed circuit board transfer tray to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a printed circuit board transfer tray, including a lower chassis and a column transverse shifting plate, a plurality of tray holes are arranged on the side of the chassis, and a circulation plate is arranged on the upper surface of the lower chassis, and a plurality of leakage openings are arranged on the circulation plate, a low bar plate is arranged at the rear end of the lower chassis, and a high bar plate is arranged at the front end of the lower chassis, a fixed sleeve plate is arranged on the upper end surface of the column transverse shifting plate, and a plurality of recessed openings are arranged on the fixed sleeve plate, and a recessed opening is also arranged on the column transverse shifting plate.

[0007] Preferably, a column is arranged in a recessed opening on the column transverse displacement plate, and a movable end is arranged at the lower end of the column, and the movable end is actively fixed inside the recessed opening.

[0008] Preferably, an embedded opening is arranged on the fixed sleeve plate, and a sliding rod is arranged inside the recessed opening on the fixed sleeve plate, and a telescopic arm is arranged on the sliding rod and placed at the embedded opening.

[0009] Preferably, a spiral column is arranged at the front end of the telescopic arm, and a bolt is arranged at the top end of the spiral column, and a deep recess is arranged in the inner opening near the bolt.

[0010] Preferably, an angled transverse plate is provided at the tail of the telescopic arm, and a soft cushion is placed at the bottom of the fixed sleeve plate.

[0011] Preferably, a straight column is arranged inside the recessed opening at the upper end of the fixed sleeve plate, and an inwardly concave transverse plate is arranged at the inward portion of the straight column.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Compared with other transfer pallet devices, this device is designed with multiple parts for structurally fixing printed circuit boards. The reinforcement of the parts prevents the printed circuit boards from being damaged due to changes in the site or environment during transportation. The buffering and stabilizing effect at special positions allows this transfer pallet to be used for printed circuit boards of different models, which is another great advantage in terms of range.

[0014] 2. Multiple pallet holes are added at the bottom of the device, which provides good transportation support points for multiple transportation methods. In addition, the inclined high and low bars allow the printed circuit board to be naturally supported downward by gravity, further ensuring the stability of the circuit board during transportation.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a printed circuit board transfer tray, including a lower chassis 1 and a column transverse shifting plate 6, a plurality of tray holes 3 are arranged on the side of the lower chassis 1, and a circulation plate 4 is arranged on the upper surface of the lower chassis 1, and a plurality of leaks 2 are arranged on the circulation plate 4. Because printed circuit boards are usually transported in multiples, the designed square transfer trays are easy to block the tray holes 3 when they are close to each other. The circulation plate 4 is designed to ensure smooth air flow and to make it easier to clean the internal dust. A low bar plate 14 is arranged at the rear end of the lower chassis 1, and a high bar plate 5 is arranged at the front end of the lower chassis 1. A soft pad 13 is arranged at the bottom of the fixed sleeve plate 7. The arrangement of the high and low bars allows the circuit boards transported on the device to naturally show a downward trend due to gravity, and the soft pad 13 at the bottom therefore bears more pressure support, so that this pressure and the front and rear thrust generated by transportation offset each other, thereby avoiding the left and right swinging caused by the fixation and causing damage;

[0022] A fixed sleeve plate 7 is arranged on the upper end surface of the column transverse moving plate 6, and recessed openings 10 are arranged on both sides of the column transverse moving plate 6. A column 8 is arranged in the recessed openings 10 on the column transverse moving plate 6, and a movable end 9 is arranged at the lower end of the column 8. At the same time, the movable end 9 is actively fixed inside the recessed opening 10. Some models of printed circuit boards have semicircular recesses on the side, and the soft fixation of the column 8 ensures its stability during transportation and transfer;

[0023] The fixing sleeve 7 is provided with recessed openings 10 on both sides, the fixing sleeve 7 is provided with an embedded opening 19, and the inside of the recessed opening 10 on the fixing sleeve 7 is provided with a sliding rod 12, and a telescopic arm 16 is provided on the sliding rod 12 and arranged at the embedded opening 19, a spiral column 17 is provided at the front end of the telescopic arm 16, and a bolt 18 is arranged at the top of the spiral column 17, and a deep recess is provided in the embedded opening 19 near the bolt 18, and an angle horizontal plate 15 is provided at the tail of the telescopic arm 16, and the telescopic arm 16 can be arranged along the sliding rod 12. Rotate and slide on it, the angled horizontal plate 15 at the bottom ensures that the turning angle of the telescopic arm 16 is vertical, the spiral column 17 and the bolt 18 at the top cooperate with each other, and are effectively installed according to the fixing holes on the circuit board. The fixation with the bolt 18 ensures the stability of transportation, and a straight column 21 is arranged inside the recessed opening 10 at the upper end of the fixed sleeve 7, and an inwardly recessed horizontal plate 20 is arranged at the inward part of the straight column 21. This part has the same effect as the above, and the upper support helps to increase the fixing height of the circuit board to prevent it from fitting with the fixed sleeve 7.

[0024] In actual use, the telescopic arms 16 and the straight columns 21 of the recessed openings 10 at the upper and side ends of the fixing sleeve 7 are adjusted to a right angle, the bolts 18 above are rotated down, the bottom end of the circuit board is first placed on the cushion 13, and the telescopic arms 16 and the straight columns 21 are slid to their respective positions in the fixing holes on the circuit board to be transported, and they are inserted and fixed according to the fixing holes, and then the bolts 18 are re-installed to ensure stability. If there are no fixing holes for different models, the fixing circles on both sides are effectively fixed with the columns 8, and finally the tray holes 3 of the lower chassis 1 are used for effective placement and transportation.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
