Description

Technical Field

[0001] The utility model relates to the technical field of circuit board detection, in particular to an automatic defective product receiving guide rail. Background Art

[0002] In existing circuit board production workshops, circuit boards are transported through guide rails and inspected by external inspection equipment. When defective products are found in the front of the guide rail, they will automatically stop on the guide rails for processing and need to be manually processed before the guide rails can resume normal operation. Since the existing guide rails lack a temporary storage mechanism, the defect of a single circuit board often causes the entire guide rail machine to stop operating for a long time. At the same time, in large-scale production processes, it is easy for manual labor to frequently remove materials from the guide rail machine, which is not only time-consuming and labor-intensive, but also seriously affects the normal operation of the guide rail machine, making it inconvenient to use.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 4 A guide rail for automatically collecting defective products includes a guide rail body 1. Conveying wheels 2 are installed on both side wall surfaces of the conveying end of the guide rail body 1. A temporary storage mechanism is installed on the surface of the guide rail body 1. The temporary storage mechanism includes a lifting plate 3. An electric push rod 31 is fixedly connected to the outer wall surface of the guide rail body 1. The upper surface of the electric push rod 31 is fixedly connected to the lower surface of the lifting plate 3. The lifting plate 3 is located on the upper surface of the guide rail body 1. The lower surface of the lifting plate 3 is fixedly connected to the mounting plate 32. A slot is opened on the side wall surface of the conveying end of the guide rail body 1. The inner wall of the slot is connected to the outer wall of the mounting plate 32. The surface is slidably connected to the inner wall of the slot, and a lifting block 33 is fixedly connected to the side wall surface of the mounting plate 32. The lifting block 33 is located between two adjacent conveying wheels 2. Multiple lifting blocks 33 are distributed in a linear array on the side wall surface of the mounting plate 32. The height of each lifting of the electric push rod 31 is the distance between adjacent lifting blocks 33. The electric push rod 31 is connected to the guide rail body 1 by signal and programmed through the PCB circuit board. After multiple lifting blocks 33 are used, the guide rail body 1 alarms to seek manual help, and then the temporarily stored circuit boards are collected.

[0024] In order to clean and maintain the surface of the conveying wheel 2, a mounting groove is provided on the side wall surface of the lower end of the lifting block 33, and the inner wall of the mounting groove is rotatably connected to the rotating shaft 34. A retaining spring 35 is installed on the surface of the rotating shaft 34 through the groove, and one end of the retaining spring 35 is tightly pressed against the inner wall of the mounting groove. The groove is provided on the surface of the rotating shaft 34 to limit the installation of the retaining spring 35, so that the retaining spring 35 pushes the rotating shaft 34, and then drives the rotating shaft 34 to deflect. The two ends of the rotating shaft 34 are fixedly sleeved with mounting rods 36, and the lower end side wall surface of one of the mounting plates 32 is rotatably connected to a cleaning roller 37 through a rotating shaft. The outer surface of the cleaning roller 37 rubs against the surface of the conveying wheel 2, so as to facilitate cleaning of impurities on the surface of the conveying wheel 2.

[0025] In order to install the cleaning roller 37, a limiting pad 38 is rotatably connected to the side wall of one end of the cleaning roller 37 through a rotating shaft. The material of the limiting pad 38 is rubber, and the lower end side wall surface of the other mounting plate 32 is rotatably connected to the side wall surface of the limiting pad 38 through a rotating shaft. The diameter of the limiting pad 38 is larger than the diameter of the cleaning roller 37, so that the limiting pad 38 can easily limit the circuit board below to prevent the circuit board below from shaking too much. A protective box 4 is fixedly connected to the side wall surface of the transport end of the guide rail body 1. The protective box 4 is open on the upper surface, and the lifting block 33 is located inside the protective box 4. The protective box 4 is used to wrap and protect multiple unused cleaning rollers 37, so as to prevent a large amount of impurities from adhering to the cleaning roller 37 itself.

[0026] By installing a temporary storage mechanism on the surface of the guide rail body 1, and installing the lifting block 33 in the temporary storage mechanism below the conveying wheel 2, when defective products are conveyed to the top of the lifting block 33, the defective products are lifted by the lifting block 33, and the cleaning blocks on both sides of the lower end of the lifting block 33 rub the surface of the conveying wheel 2 and clean the impurities on the surface of the conveying wheel 2, thereby making it convenient for the temporary storage mechanism to temporarily store defective products and facilitate the cleaning and maintenance of the conveying wheel 2.

[0027] A baffle 5 is fixedly connected to the upper surface of the conveying end of the guide rail body 1, and one lifting plate 3 is located inside the baffle 5. The lifting plate 3 is used to lift inside the baffle 5, thereby avoiding affecting the use of the lifting plate 3.

[0028] Working principle:

[0029] When in use, the guide rail body 1 transports the circuit board via the transport wheel 2;

[0030] When defective products are transported to the top of the lifting block 33, the electric push rod 31 is activated, and the electric push rod 31 lifts the lifting block 33 through the lifting plate 3 and the mounting plate 32, and the upper surface of the lifting block 33 lifts the lower surface edge of the circuit board;

[0031] At the same time, the cleaning roller 37 at the lower end of the lifting block 33 is exposed from the protective box 4. The surface of the cleaning roller 37 loses the squeezing of the inner wall of the protective box 4. The retaining spring 35 pushes the rotating shaft 34. The rotating shaft 34 drives the cleaning roller 37 to deflect upward through the mounting rod 36. The surface of the extended cleaning roller 37 contacts the surface of the conveying wheel 2. As the lifting block 33 rises, the cleaning roller 37 rubs against the surface of the conveying wheel 2 and sweeps away impurities on the surface of the conveying wheel 2. Repeat the above actions. After circuit boards are temporarily stored on the surfaces of multiple lifting blocks 33, the guide rail body 1 alarms and seeks manual help.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
