Description

[0002] A circuit board, also known as a printed circuit board (PCB) or a printed wiring board, is a support body and a carrier for electrical connection of electronic components. In the production process of a circuit board, glue is usually filled in the circuit board to enhance its resistance to external impact and vibration and improve the insulation performance between internal circuits. After the glue is filled, the circuit board is usually pressed to tightly combine the glue and the circuit board and form stable electrical connection and mechanical support.

[0003] In the process of filling glue in a circuit board according to the prior art, if the amount of glue applied is too much or uneven, excess glue will be generated. However, in the process of pressing the circuit board filled with glue according to the prior art, only pressure is applied to the surface of the circuit board, and the excess glue on the surface of the circuit board cannot be scraped off. Therefore, with the presence of the excess glue, the glue will gradually cover or penetrate into the electrical connection part, resulting in a decrease in electrical performance or short circuit. In addition, the excess glue will form irregular protrusions or residues on the circuit board, thereby increasing the mechanical stress of the circuit board during use and affecting the appearance quality of the circuit board.

[0051] Compared with the prior art, through the moving scraping mechanism, the excess glue on the circuit board can be scraped off before the pressing plate 5 is pressed to the circuit board, so as to avoid the existence of the excess glue which covers or penetrates into the electrical connection part, resulting in the electrical performance decline or short circuit, and the scraping of the excess glue can also effectively prevent the excess glue from forming irregular protrusions or residues on the circuit board, so as to reduce the mechanical stress of the circuit board in use and improve the appearance quality of the circuit board.

[0053] Compared with the prior art, the guiding and collecting mechanism can guide and collect the excess glue scraped off the circuit board by the moving scraping mechanism, avoid the influence of the subsequent processing and use of the circuit board due to the excess glue left on the surface of the workbench 2, thereby maintaining the cleanliness of the surface of the workbench 2, and the collection of the glue can also facilitate the recycling of the glue, thereby reducing the use cost of the glue and unnecessary waste of resources, and being conducive to environmental protection.

[0054] In other aspects, the embodiment also provides a synchronous cleaning mechanism, as shown in Figure 1 Figure 7 As shown, the synchronous cleaning mechanism comprises a scraper 705 fixedly connected to the bottom of the linkage frame 703, a fixed plate 901 is fixedly connected to the bottom of the linkage frame 703 symmetrically with the scraper 705 as the center, and a cleaning plate 903 is also symmetrically and slidably connected to the bottom of the linkage frame 703 with the scraper 705 as the center, the cleaning plate 903 is provided as two and is located on both sides of the scraper 705, and can clean both sides of the scraper 705 when started subsequently, and the glue adhered to both sides of the scraper 705 is removed, thereby ensuring the cleanliness of the scraper 705 and avoiding the influence of the subsequent scraping work of the excess glue on the surface of the circuit board due to the glue left on the scraper 705.

[0055] In the embodiment, as shown in Figure 4 ​As shown, the fixed plate 901 is fixedly connected with an electric telescopic rod 902, one end of the electric telescopic rod 902 away from the fixed plate 901 is clamped with a cleaning plate 903, the top of the sliding frame 704 is provided with a connecting groove, the bottom of the linkage frame 703 is fixedly connected with a connecting block, and the connecting block is slidingly connected in the connecting groove, one end of one of the connecting grooves towards the gear 601 is provided with a switch, and the switch is electrically connected with the electric telescopic rod 902, so when the linkage frame 703 is driven to move to the left side of the workbench 2 (i.e. close to the gear 601), the connecting block installed at the bottom of the linkage frame 703 will slide in the connecting groove, and finally move to the switch to touch and open the switch, at this time, the switch can drive the electric telescopic rod 902 to start running synchronously, driving the cleaning plate 903 to slide at the bottom of the linkage frame 703, cleaning the outer walls on both sides of the scraper 705, it should be noted that when the linkage frame 703 moves from the side away from the gear 601 to the side close to the gear 601, the scraper 705 will be located above the collecting box 802, at this time, the glue residues cleaned by the cleaning plate 903 will fall into the collecting box 802 for collection.

[0056] Compared with the prior art, through the synchronous cleaning mechanism, the outer walls on both sides of the scraper 705 can be cleaned synchronously during the continuous pressing of the pressing plate 5, so as to ensure the cleanliness of the surface of the scraper 705, avoid the residual glue on the scraper 705, and make the glue harden and firmly adhere to the surface of the scraper 705 over time to affect the next scraping work of the excess glue on the surface of the circuit board.

[0057] The working process and principle involved in the above embodiment are as follows:

[0058] In use, the worker can first clamp the circuit board on the upper surface of the workbench 2 through the existing clamp, and then use the glue pouring equipment to pour glue on the surface of the circuit board, it is known that the manufacturing steps of the circuit board also need to be pressed, therefore, when the device is used, the auxiliary plate 4 fixedly connected with the output end of the cylinder 3 can be driven to move downward synchronously by the starting of the cylinder 3, since the auxiliary plate 4 is clamped with the limiting plate 607 through the fixed block 610, the downward movement of the auxiliary plate 4 can drive the extension rod 606 fixedly connected with the limiting plate 607 to move downward synchronously, at this time, the extension rod 606 will drive one of the push rods 605 to move towards the screw rod 602 under the action of downward movement, and synchronously drive the other push rod 605 to move towards the inside of the sleeve 612, and since the inner surface of the screw rod 602 is provided with a threaded groove, as Figure 5As shown, a driving block 603 is fixed to the bottom of the push rod 605 corresponding to the threaded rotating rod 602, and a sliding ball 604 adapted to the thread groove is installed on the outer surface of the driving block 603. Therefore, when the push rod 605 moves downward, the sliding ball 604 will slide synchronously inside the thread groove. As the sliding ball 604 continues to move, the threaded rotating rod 602 will rotate synchronously on the base frame 1, as shown in FIG. Figure 2 As shown, since a gear 601 is fixed on the outer surface of the threaded rotating rod 602, and the gear 601 is meshed and connected with the gear ring 701, when the gear 601 rotates, the gear ring 701 is meshed and driven to rotate synchronously on the base frame 1, and at this time the mobile scraping mechanism is activated and starts to operate, as shown below;

[0059] When the gear ring 701 is driven to rotate on the base frame 1, the lever 702 on the gear ring 701 moves synchronously. Figure 2 As shown, it can be seen that the center of the lever 702 and the gear ring 701 are not in the same position. The lever 702 is installed off-axis. Therefore, when the gear ring 701 rotates, it can drive the lever 702 to rotate off-axis, and drive the linkage frame 703 slidably connected to its surface to move between the two slides 704 in the direction of the gear 601. Because a scraper 705 is fixed to the bottom of the linkage frame 703 and the height of the linkage frame 703 is higher than the workbench 2, when the linkage frame 703 moves, it can drive the scraper 705 to move synchronously above the workbench 2 to scrape off excess glue on the surface of the placed circuit board;

[0060] like Figures 1 to 3 As shown, a guide and collection mechanism is provided on the left side of the workbench 2 (i.e., the end close to the gear 601), and a collection box 802 in the guide and collection mechanism is attached to the side of the workbench 2, and a guide plate 803 is installed on the collection box 802. When in use, the higher end of the guide plate 803 can be attached to the edge of the circuit board, so that when the scraper 705 moves to scrape off excess glue on the circuit board, the glue is introduced into the collection box 802 through the guide plate 803, and the excess glue is collected, so as to prevent the glue from remaining on the surface of the workbench 2 and affecting the subsequent processing and use of the circuit board;

[0061] It should be noted that a connecting slot is provided at the top of the slide 704, and a connecting block is symmetrically fixedly connected to the bottom of the linkage frame 703, and the connecting block is slidably connected to the connecting slot. A switch is provided at one end of the connecting slot facing the gear 601, and the switch is electrically connected to the electric telescopic rod 902;

[0062] Therefore, when the linkage frame 703 is driven to move to the left side of the workbench 2 (i.e., close to the gear 601) by the rotating movement of the dial lever 702, the connecting block installed at the bottom of the linkage frame 703 will slide in the connecting groove and finally move to the switch to touch and open the switch. At this time, the switch can drive the electric telescopic rod 902 to start running synchronously, and the cleaning plate 903 slides at the bottom of the linkage frame 703 to clean the outer walls on both sides of the scraper 705. It should be noted that when the linkage frame 703 moves from the side away from the gear 601 to the side close to the gear 601, the scraper 705 is above the collection box 802. At this time, the glue residues cleaned by the cleaning plate 903 will fall into the collection box 802 for collection.

[0063] Due to the limited length of the threaded rotating rod 602, and the auxiliary plate 4 is clamped on the limiting plate 607 through the fixed block 610, during the process of the cylinder 3 driving the auxiliary plate 4 to move downward, the driving block 603 is first driven to move downward in the threaded rotating rod 602. When the driving block 603 reaches the bottom of the threaded rotating rod 602, the driving block 603 will be limited by space and cannot continue to move. At this time, under the continuous pushing action of the cylinder 3, the spring positioning blocks 611 installed on both sides of the fixed block 610 will be pushed and separated from the inside of the positioning groove 609, and the clamping connection with the limiting plate 607 is lost. At this time, as shown in Figure 6 and Figure 7 The fixed block 610 will slide downward in the sliding groove 608 under the pushing action of the downward movement of the auxiliary plate 4, and finally make the pressing plate 5 installed at the bottom of the auxiliary plate 4 contact with the circuit board to press the circuit board. It should be noted that the driving block 603 is in a static state during this process, so the gear 601 does not rotate, and the linkage frame 703 stays at the end of the sliding frame 704 close to the gear 601, so that the connecting block at the bottom of the linkage frame 703 contacts with the switch in the connecting groove of the sliding frame 704 to start the electric telescopic rod 902 to run and scrape off the excess glue on both sides of the scraper 705.

[0064] After the circuit board is pressed and combined, the worker can take out the circuit board from the clamp, and then use the cylinder 3 to reversely contract to drive the auxiliary plate 4 to move upward. At the initial stage of the reverse operation of the cylinder 3, the fixed block 610 will slide upward in the sliding groove 608. When the fixed block 610 slides to the upper end of the sliding groove 608, the spring positioning blocks 611 will be clamped with the positioning groove 609, and then through the clamping with the limiting plate 607, the driving block 603 will move upward from the inside of the threaded rotating rod 602. At this time, the dial lever 702 rotates reversely to push the linkage frame 703 away from the gear 601, so as to complete the position recovery work of the linkage frame 703.
