[0002] Gluing is a key step in the PCB manufacturing process, mainly used to protect the circuit board from environmental factors such as moisture, dust and chemicals. Gluing materials usually have moisture-proof, dust-proof, insulating and high temperature resistance properties, which can effectively improve the stability and reliability of the circuit board.

[0003] When the surface of the PCB board is coated with glue, the electronic components and pins need to be shielded to prevent the glue from affecting the normal operation of the electronic components and pins. The existing operation is to shield them by sticking tapes, stickers, etc. Since the pins of the electronic component box are in many places on the surface of the PCB board, the pasting and removal process is relatively cumbersome, and the tapes and stickers are disposable, and the production cost is high.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] like Figure 1-3 As shown, the utility model proposes a PCB board gluing shaping structure, comprising a transmission platform 11, the transmission platform 11 has a movable transmission belt 12 built therein, and the transmission belt 12 is provided with PCB board racks 13 with placement slots at intervals;

[0024] A shaping table 2 is arranged above the PCB board rack 13, and a plurality of shielding covers 4 are arranged on the shaping table 2;

[0025] The shaping mechanism includes an inner support frame 31 arranged on the inner wall of the shaping table 2 and an edge banding frame 34 arranged on the outer wall of the shielding cover 4. The inner support frame 31 and the edge banding frame 34 are connected by a combination plate 32.

[0026] The lifting mechanism includes a cylinder 51 arranged outside the shaping table 2, a movable piston rod 52 is installed at the output end of the cylinder 51, and a push plate 53 is installed at the other end of the piston rod 52. The push plate 53 is connected to the side wall of the shaping table 2 through a supporting angle seat 54.

[0027] It should be noted that: the shaping table 2 and the PCB board rack 13 are arranged in parallel, and the shaping table 2 is inserted into the inner cavity of the PCB board rack 13 to clamp the PCB board in the surrounding area; wherein the electronic component part of the PCB board is inserted into the inner cavity of the shielding cover 4.

[0028] In this embodiment, since a number of electronic components of different specifications are arranged on the PCB board according to functional zoning, a matching shielding cover is arranged on the shaping table 2 according to the specifications of the electronic components on the PCB board, and a cavity with the same specifications as the electronic components on the PCB board is opened inside the shielding cover 4. Each shielding cover 4 is installed on the inner support frame 32 through the combination plate 32 and the edge banding frame 34. When the lifting mechanism works, the cylinder 51 drives the piston rod 52 to contract and drive the push plate 53 to move. At this time, the supporting angle seat 54 drives the shaping table 2 to press down, and the pins and the shell at the bottom of the electronic components are covered and shielded by the shielding cover 4. A glue coating area is reserved on the surface of the PCB board clamped by the shaping table 2 and the PCB board frame 13, and the exposed area is coated with glue by an external glue coating device to prevent the glue from affecting the electronic components and pins;

[0029] After the glue coating is completed, the shaping table 2 can be pushed upward to separate from the PCB board rack 12. During the displacement of the conveyor belt 12, the PCB board rack 12 is pushed forward, and the PCB board rack 12 that is not coated with glue is placed under the shaping table 2. The above steps are repeated to continuously coat the PCB board with glue. During the continuous coating process, the shaping table 2 and the shaping mechanism are reused and can be easily separated, which reduces production costs while improving production efficiency.

[0030] like Figure 2 As shown, inclined ramp plates 33 are provided at both ends of the combined board 32 , and the combined board 32 between the two ramp plates 33 has no contact with the PCB board.

[0031] The purpose of setting the ramp 33 is to leave a glue channel between the combined board 32 and the surface of the PCB board to prevent the combined board 32 from being directly attached to the surface of the PCB board, resulting in gaps in the glue coating.

[0032] It should be supplemented that: the shielding cover 4 adapted to each electronic component is connected to the inner support frame 31 through the combination plates 32 of different lengths, but each combination plate is provided with the same inclined ramp to facilitate the reservation of the channel.

[0033] In order to facilitate the movement of the shaping table 2, further, the supporting angle seat 54 is a "Z-shaped" structure, which rises and falls synchronously with the piston rod 52, and is symmetrically installed in pairs on the side walls of the shaping table 2 to clamp the shaping table 2 for movement.

[0034] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
