Description

Technical Field

[0001] The utility model belongs to the technical field of chip processing devices, and particularly relates to an SMT patch conveying device. Background Technique

[0002] SMT refers to surface mount technology, which is an electronic assembly technology mainly used for directly soldering electronic components onto a printed circuit board (PCB). Compared with the traditional through-hole insertion technology, SMT has the advantages of high-density wiring, high production efficiency, and good electrical performance. At the same time, the surface mount technology supports various types of components, including chip resistors, capacitors, integrated circuits, etc., and can meet diverse design requirements.

[0003] An SMT patch conveying device is a device used in a surface mount technology (SMT) production line, mainly responsible for conveying printed circuit boards (PCBs) and patch components during the production process. The conveying device is connected to the component material station, enabling the pick-and-place machine to obtain the required components and ensuring the high efficiency of the production process. In the prior art, when conveying a circuit board, the circuit board is placed on a tray for transportation. The tray can ensure the neatness of the conveyed circuit board and facilitate subsequent patching work. However, in the prior art, the size of the tray is not fixed. When using a smaller-sized tray, the tray will sway left and right on the conveyor belt of the conveying device, causing the chips in the tray to be mixed together, which is inconvenient for subsequent processing and production. When the size of the tray is larger, the tray cannot be placed on the conveyor belt. Therefore, the conveying device in the prior art has the problem of being unable to adapt to trays of different specifications.

[0004] In a Chinese patent with the publication number CN110626813A, a fully automatic circuit board batching and conveying process device is disclosed. This conveying process device uses a tray sensor to monitor the position of the tray, facilitating the loading and unloading of the circuit board. Using a conveying device with this structure requires the use of a special tray, which cannot adapt to trays of different specifications and has poor applicability, unable to meet the processing requirements.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment:

[0030] An SMT patch conveying device, as Figure 1 shown, includes a bottom plate 1, a left half machine 6, a right half machine 2, a left conveyor belt 5, a right conveyor belt 4, and an adjusting device. The left half machine 6 and the right half machine 2 are symmetrically arranged on the bottom plate 1;

[0031] As Figure 3 shown, the left half machine 6 is fixedly connected to the bottom plate 1, the left conveyor belt 5 is connected to the left half machine 6, and the left half machine 6 is used to drive the left conveyor belt 5 to rotate; the right half machine 2 is movably connected to the bottom plate 1, the right conveyor belt 4 is connected to the right half machine 2, and the right half machine 2 is used to drive the right conveyor belt 4 to rotate. The adjusting device is connected to the right half machine 2; it should be noted that the rotation speeds of the left conveyor belt 5 and the right conveyor belt 4 should be kept consistent. During use, the tray 3 is placed above the left conveyor belt 5 and the right conveyor belt 4, and the left conveyor belt 5 and the right conveyor belt 4 with the same rotation speed can ensure the stable movement of the tray 3.

[0032] As Figure 3 shown, the adjusting device includes a mounting plate 10 and an adjusting screw rod 9; wherein, the mounting plate 10 is fixedly connected to the bottom plate 1, the adjusting screw rod 9 is rotatably connected to the mounting plate 10, and the right half machine 2 is threadedly connected to the adjusting screw rod 9. Through the threaded connection between the right half machine 2 and the adjusting screw rod 9, the right half machine 2 can be moved by rotating the adjusting screw rod 9. The self-locking ability of the adjusting screw rod 9 is utilized to ensure that the position of the adjusted right half machine 2 will not change.

[0033] Specifically, during use, first adjust the distance between the left half machine 6 and the right half machine 2 according to the specification of the tray 3, so as to facilitate placing the tray 3 on the left conveyor belt 5 and the right conveyor belt 4. Rotate the adjusting screw rod 9, and the adjusting screw rod 9 will drive the right half machine 2 to move when rotating. Adjust the distance between the left half machine 6 and the right half machine 2 according to the specification of the tray 3, so that it is just right to place the tray 3. After the adjustment is completed, place the tray 3 on the left conveyor belt 5 and the right conveyor belt 4, and place the circuit board in the tray 3 for transmission. Through this design of the present utility model, trays 3 of different specifications can be adapted to the conveying device.

[0034] In a preferred embodiment, as Figure 3As shown, a fixed plate 8 is fixedly connected to the bottom plate 1, a limit slide bar 7 is fixedly connected to the fixed plate 8, and the right half machine 2 is slidably connected to the limit slide bar 7. By providing the limit slide bar 7, a stable and controllable moving range can be provided for the right half machine 2.
