Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a resin plugging structure for a circuit board. Background Technology

[0002] In the process of circuit board manufacturing, buried vias are usually required. Resin plugging simply means that after the hole wall is plated with copper, the via is filled with epoxy resin and then copper is plated on the surface. With resin plugging process, there are no dents on the surface of the circuit board, the hole can conduct electricity and does not affect the soldering. Therefore, it is favored for some products with high layer count and large board thickness.

[0003] In the prior art, when resin plugging is performed on circuit boards, the circuit boards are usually placed manually in the filling area of ​​the filling equipment for filling. When resin plugging is performed on circuit boards, a large number of circuit boards usually need to be filled. Manual loading is time-consuming, labor-intensive, and affects work efficiency. Therefore, a loading structure for resin plugging on circuit boards is proposed to solve the above problems. Utility Model Content

[0008] Furthermore, a storage cavity is formed on the front of the body, the groove is connected to the interior of the storage cavity, a cylinder is fixed to the inner bottom wall of the storage cavity, a support plate is fixed to the outer side of the cylinder output shaft, the support plate is slidably connected in the storage cavity, and a gap is left between it and the inner top wall of the storage cavity.

[0009] Furthermore, the support plate moves linearly within the storage cavity, and the length and width of the support plate are adapted to the length and width of the inner cavity of the storage cavity.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] 1.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Example 1:

[0019] Please see Figure 1-2This embodiment describes a resin plugging structure for a circuit board, comprising a body 1 corresponding to a conveyor. The body 1 has several horizontally oriented grooves 2 and a filler 3. A conveyor assembly is provided on the body 1 corresponding to each groove 2. The conveyor assembly includes a motor 42, rotating rods 46, and pulleys 45. Several rotating rods 46 are rotatably connected to the top surface of the body 1. These rotating rods 46 are evenly spaced horizontally corresponding to the grooves 2 and symmetrically distributed on the front and rear sides of the grooves 2. A sprocket 44 is fixed to the outer side of each rotating rod 46. A chain 43 is driven to the outer side of each sprocket 44 on the same horizontal axis. The top of one of the rotating rods 46 is connected to the output shaft of the motor 42. A pulley 45 is fixed to the rotating rod 46, and a circuit board conveying channel is formed between the front and rear pulleys 45.

[0020] In application, the circuit board is transported to the top surface of the machine body 1 via a conveyor and moves into the circuit board transport channel. At this time, the motor 42 operates, driving one of the rotating rods 46 to rotate. After the rotating rod 46 rotates, the corresponding sprocket 44 and pulley 45 rotate synchronously. This sprocket 44, via the chain 43, drives other sprockets on the same horizontal axis to rotate. After the other sprockets 44 rotate, their corresponding rotating rods 46 and pulleys 45 also rotate synchronously. After all the pulleys 45 have rotated, the circuit board located in the circuit board transport channel contacts the pulleys 45 and moves within the channel under the action of the pulleys 45. After moving into the groove 2, the circuit board will fall into the groove 2. At this time, the top surface of the circuit board is flush with the top surface of the machine body 1. After the first circuit board enters the groove 2, the subsequent circuit board will pass through the circuit board and fall into the next groove 2. After all the circuit boards have entered the groove 2, the conveyor and motor 42 stop working, and other circuit boards are no longer conveyed. The filling part 3 on the machine body 1 can perform resin plugging work on the circuit boards in the groove 2. The circuit boards are conveyed by rotating pulley 45. It is no longer necessary to manually place the circuit boards into the groove 2, which effectively reduces labor input, reduces production costs, and improves the efficiency of circuit board loading.

[0021] Example 2:

[0022] The basic content is from Example 1, the difference being:

[0023] Please see Figure 1-2 In this embodiment, a mounting plate 41 is fixed on the body 1, and a motor 42 is fixed on the mounting plate 41. The mounting plate 41 is an L-shaped plate. The sprocket 44 is located above the pulley 45. A gap is formed between the bottom surface of the pulley 45 and the top surface of the body 1. The side wall of the groove 2 near the pulley 45 is flush with the outer side of the pulley 45 near the groove 2.

[0024] In application, the motor 42 mounted on the mounting plate 41 drives the pulley 45 to rotate via the drive rod 46, which allows the circuit board to move within the circuit board transmission channel. When the pulley 45 rotates and drives the circuit board to move, the gap formed between the pulley 45 and the machine body 1 allows the pulley 45 to rotate more smoothly, thereby improving the transmission effect of the circuit board.

[0025] Example 3:

[0026] The basic content is from Example 1, the difference being:

[0027] Please see Figure 1 and Figure 3 In this embodiment, the front of the body 1 has a storage cavity 6. The groove 2 is connected to the interior of the storage cavity 6. A cylinder 7 is fixed to the inner bottom wall of the storage cavity 6. A support plate 5 is fixed to the outer side of the output shaft of the cylinder 7. The support plate 5 is slidably connected in the storage cavity 6 and has a gap with the inner top wall of the storage cavity 6. The support plate 5 makes an upward linear movement in the storage cavity 6. The length and width of the support plate 5 are adapted to the length and width of the inner cavity of the storage cavity 6.

[0028] During application, the circuit board that enters the groove 2 will fall onto the support plate 5 and be supported by the support plate 5. After the circuit board on the support plate 5 is filled with resin, the cylinder 7 operates and drives its output shaft to retract, causing the support plate 5 to move downward. The circuit board on the support plate 5 also moves with it. After the support plate 5 moves the circuit board out of the groove 2, the operator takes out the circuit board with the resin-filled hole completed. Then the cylinder 7 resets the support plate 5, and the conveyor and motor 42 work again to convey other circuit boards into the groove 2. The support plate 5 supports these circuit boards again, and then the resin filling work can be performed on these circuit boards.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
