Description

Technical Field

[0001] This utility model relates to the field of PCB production and processing equipment, specifically to an automatic PCB code reading, conveying, and sorting device. Background Technology

[0002] In modern printed circuit board (PCB) production processes, PCBs are typically identified and classified. PCBs are printed with QR codes or barcodes that contain key information such as the board's model, batch number, production data, and whether it is a good or defective product.

[0003] These QR codes or barcodes are read quickly and accurately, and the PCBs are automatically sorted to different flows based on the reading results (e.g. qualified products flow into the next process, and unqualified products enter the rework area).

[0004] Currently, many factories still rely heavily on manual operation in this stage. Workers need to manually pick up each PCB, read the barcode using a handheld scanner, and then place it onto different carts or pallets based on system prompts or experience. Manual operation is extremely inefficient and labor-intensive; errors in manual identification and sorting are unavoidable, easily leading to product mixing and incorrect flow; furthermore, workers may cause scratches, electrostatic damage, or physical impacts to the delicate PCBs during frequent handling. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic PCB code reading, conveying, and sorting device, comprising a frame, with an infeed flow line, a glass platform, an outfeed flow line, a connecting flow line, a buffer device, and a lower code reading module arranged on the lower side of the frame; the frame is equipped with an loading robot, an upper code reading module, and an unloading robot; the output ends of the loading robot and the unloading robot are fixedly connected to a base; an adjustable adsorption component is arranged on the base; the glass platform is located between the infeed flow line and the outfeed flow line; the connecting flow line is connected to one outlet of the outfeed flow line; the upper code reading module and the lower code reading module have the same structure; the lower code reading module includes an XY movement module, a camera, and an adjustment platform.

[0007] Furthermore, the glass platform includes a platform base, a glass plate, and positioning blocks. The platform base is fixedly connected to the frame, and the glass plate and positioning blocks are detachably connected to the platform base. The positioning blocks are located around the glass plate.

[0008] Furthermore, the buffer device includes a buffer platform and an automatic paper feeding mechanism, both of which are fixedly connected to the frame.

[0009] Furthermore, the adjustable adsorption component includes a linear module, and a floating adsorption mechanism is fixedly connected to both the base and the moving platform of the linear module.

[0010] Furthermore, the floating adsorption mechanism includes a floating seat, a spring, an adsorption seat plate, and a vacuum nozzle. The adsorption seat plate is slidably connected to the floating seat, the spring is located between the floating seat and the adsorption seat plate, and the vacuum nozzle is fixedly connected to the adsorption seat plate.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] Please see Figure 1-5 The illustrated PCB automatic barcode reading, conveying, and sorting equipment includes a frame. The frame has an infeed flow line 1, a glass platform 2, an outfeed flow line 3, a connecting flow line 4, a buffer device 5, and a lower barcode reading module 6. The frame also includes an loading robot 7, an upper barcode reading module 8, and an unloading robot 10. The output ends of both the loading robot 7 and the unloading robot 10 are fixedly connected to a base 11. An adjustable adsorption component 9 is mounted on the base 11. The glass platform 2 is located between the infeed flow line 1 and the outfeed flow line 3. The connecting flow line 4 is connected to one of the outfeed ports of the outfeed flow line 3. The upper barcode reading module 8 and the lower barcode reading module 6 have the same structure. The lower barcode reading module 6 includes an XY motion module 601, a camera 602, and an adjustment platform 603.

[0022] The glass platform 2 includes a platform base 201, a glass plate 202, and a positioning block 203. The glass plate 202 is used to place PCB products, and the glass plate is a transparent material to facilitate the scanning of the code by the code reading module 6. The positioning block 203 is used to position the PCB material.

[0023] The buffer device 5 includes a buffer platform 501 and an automatic paper feeding mechanism 502. The buffer platform 501 is used to store defective PCBs, and the automatic paper feeding mechanism 502 is used to store stacked paper dividers and automatically lift the paper dividers to achieve feeding.

[0024] The adjustable adsorption assembly 9 includes a linear module 901, and a floating adsorption mechanism is fixedly connected to the base 11 and the moving platform of the linear module 901.

[0025] The distance between the two floating adsorption mechanisms can be adjusted by the linear module 901 to achieve adsorption and transfer of PCBs of different sizes. When picking up and putting down materials, the adsorption seat plate 904 can float up and down relative to the floating seat 902.

[0026] The adjustment platform 603 is fixedly connected to the moving stage of the XY moving module 601, and the adjustment platform 603 can finely adjust the position and angle of the camera 602.

[0027] The working principle of this utility model is as follows: After the PCB flows into the feeding flow line, the adjustable adsorption component 9 driven by the feeding robot 7 adsorbs the PCB and transfers it to the glass plate 202. The upper barcode reading module 8 and the lower barcode reading module 6 respectively take pictures and read the barcodes on both sides of the PCB. According to the barcode information, if the PCB is a qualified product, the adjustable adsorption component 9 driven by the feeding robot 7 adsorbs the PCB and transfers it to the discharge flow line 3. It is then transported to the connecting flow line 4 through one discharge end of the discharge flow line 3. If the PCB is a defective product, the adjustable adsorption component 9 driven by the unloading robot 10 adsorbs the PCB and transfers it from the other discharge end of the discharge flow line 3 to the buffer platform 501 for reset. Then, the unloading robot 10 drives the adjustable adsorption component 9 to move to the automatic paper feeding mechanism 5 to adsorb a paper and place it on the PCB to wait for the next defective PCB to be placed.
