Description

Technical Field

[0001] The utility model relates to the technical field of PCB board manufacturing, in particular to a PCB board gluing device. Background Art

[0002] PCB, Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, the support of electronic components, and the carrier for the electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board, and its production process involves painting. Specifically, the purpose of painting PCB boards is to form a protective coating on their surface to provide waterproof, moisture-proof, dust-proof, corrosion-proof, mildew-proof, and enhance the insulation performance of the circuit board.

[0003] However, the PCB board may contain some components that are sensitive to spray paint or specific chemicals, such as LED lights, connectors, power switches, etc. If these components are covered with spray paint, their performance may be degraded or damaged. Therefore, before spray painting, you need to stick adhesive tape on these sensitive components to prevent the spray paint from contacting them.

[0004] At present, a Chinese patent with the announcement number CN219019151U discloses a PCB board gluing device, including a carrier, an electric telescopic seat is slidably provided on the carrier through an electric slide rail, a roller is provided on the ejection end of the electric telescopic seat, and the tape used for gluing is installed on the roller. In addition, an extension seat is also provided on the side wall of the ejection end of the electric telescopic seat, and an electric cutter is provided on the extension seat. When in use, the PCB board is conveyed to the bottom of the electric telescopic seat, and then the electric telescopic seat ejects the tape tightly against the board body and slides synchronously, so that the tape is attached to the board body; finally, the electric cutter ejects and cuts the tape. However, the tape of the above-mentioned gluing device relies on the electric cutter to complete the cutting, and the use of the electric cutter increases the number of driving parts of the device, which not only increases the energy consumption, but also increases the system complexity of the device, and reduces the reliability of the device. Utility Model Content

As the electric telescopic seat is transferred, when the protrusion is opposite to the connecting rod, the blade is ejected to cut the tape.

[0008] The protrusion is configured with a driving arc surface for ejecting the connecting rod.

[0009] A guide wheel is rotatably arranged on the end of the connecting rod away from the blade.

[0010] The protrusion is adapted to be movable on the mounting bracket to change the ejection position of the connecting rod.

[0011] A connecting plate is provided at the end of the mounting frame, an airbag is provided between the connecting plate and the electric telescopic seat, the airbag can be squeezed as the electric telescopic seat is shifted, an injection pipe is connected to the airbag, and the injection pipe extends to the injection end opposite to the rotating shaft.

[0014] The mounting frame is provided with a slide rail, the protrusion is slidably adapted to the slide rail, and the protrusion is provided with a magnet, and the electric telescopic seat is provided with an electromagnet, which can absorb the magnet when energized, thereby driving the protrusion to move synchronously with the electric telescopic seat.

[0015] The beneficial effect of the utility model is that after the electric telescopic seat completes the gluing of the PCB board with the rotating shaft, the connecting rod will gradually face the protrusion, and under the abutment of the protrusion, the connecting rod will drive the blade to push out and complete the cutting of the tape. Compared with the prior art, the PCB board gluing device of the utility model can achieve the cutting of the tape without additional power through the cooperation of the connecting rod, the blade and the protrusion, so the energy consumption of the device is controlled, the system complexity is reduced, and the reliability of use is correspondingly improved.

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , Figure 2 As shown, a PCB board gluing device comprises a mounting frame 1, an electric slide rail is arranged on the mounting frame 1, and an electric telescopic seat 2 is arranged on the transfer component of the electric slide rail. Among them, a rotating shaft 3 is rotatably arranged on the ejection end of the electric telescopic seat 2, and the adhesive tape used for gluing is installed on the rotating shaft 3. When gluing, the PCB board is conveyed to the bottom of the electric telescopic seat 2, and then the electric telescopic seat 2 ejects the adhesive tape tightly against the board body, and the electric telescopic seat 2 slides synchronously under the action of the electric slide rail, and the rotating shaft 3 rotates to gradually stick the adhesive tape on the board body.

[0021] In order to achieve the cutting of the adhesive tape, in the present disclosure, a resilient connecting rod 4 is provided on the side wall of the electric telescopic seat 2. For example, a mounting seat is provided on the side wall of the electric telescopic seat 2, and the connecting rod 4 and the mounting seat are resiliently connected via an elastic member, so that the connecting rod 4 can be resilient to one side of the adhesive tape. In more detail, a blade 5 is provided on the end of the connecting rod 4, and a protrusion 6 is provided on the mounting frame 1. In the process of the electric telescopic seat 2 being transferred for adhesive application, the connecting rod 4 will gradually approach the protrusion 6 until the connecting rod 4 is opposite to the protrusion 6, and under the contact of the protrusion 6, the connecting rod 4 will drive the blade 5 to push out to complete the cutting of the adhesive tape.

[0022] In a preferred example, the side wall of the protrusion 6 facing the connecting rod 4 is configured as a driving arc surface 7, or the side wall can also be configured as an inclined surface. When the connecting rod 4 abuts against the protrusion 6, under the guidance of the driving arc surface 7, the connecting rod 4 can eject the blade 5 more smoothly and stably. For example, a guide wheel 8 is preferably rotatably provided on the end of the connecting rod 4 away from the blade 5, and the sliding friction between the connecting rod 4 and the protrusion 6 can be converted into rolling friction through the guide wheel 8, thereby further improving the ejection stability of the connecting rod 4.

[0023] In some embodiments, the protrusion 6 is also adapted to be able to move on the mounting frame 1. For example, a lead screw 12 is rotatably provided on the mounting frame 1, and the protrusion 6 is mounted on the nut of the lead screw 12. Among them, the transmission of the lead screw 12 is a prior art, and its specific principle and structure are not repeated in this disclosure. In short, as the lead screw 12 rotates, the nut can drive the protrusion 6 to move axially, thereby changing the relative position of the protrusion 6 on the mounting frame 1, and finally realizing the adjustment of the ejection position of the connecting rod 4.

[0024] Therefore, when the size of the PCB board to be glued changes or the size of the area to be glued changes, the protrusion 6 can be adjusted to change the ejection position of the connecting rod 4 to achieve cutting of the tape after different transfer strokes of the electric telescopic seat 2.

[0025] As another solution, the mounting seat is further provided with a slide rail, the protrusion 6 is slidably adapted to the slide rail, and a magnet (not shown) is provided on the protrusion 6, and an electromagnet 13 is correspondingly provided on the electric telescopic seat 2. It can be understood that when the electromagnet 13 is energized, it can generate an adsorption force on the magnet, thereby driving the protrusion 6 to move synchronously with the movement of the electric telescopic seat 2.

[0026] In this scheme, when the size of the PCB board to be glued changes or the size of the area to be glued changes, the electromagnet 13 can be controlled to be energized to attract the magnet, and the protrusion 6 can be transferred to the expected ejection position of the connecting rod 4 by the transfer of the electric telescopic seat 2, and then the electromagnet 13 is controlled to be de-energized. Compared with the above-mentioned form of transmission by the lead screw 12, the adjustment of the ejection position of the protrusion 6 is achieved by electromagnetic adsorption, which not only utilizes the transfer power of the original electric slide rail, but also reduces the complexity of mechanical assembly, making the PCB board gluing device disclosed in this disclosure more reliable.

[0027] It should be noted that the sliding between the protrusion 6 and the slide rail can be adapted to have a certain damping, so that when the connecting rod 4 abuts against the protrusion 6, it is not easy to push the protrusion 6 to slide.

[0028] In some embodiments, a connecting plate 9 is provided at the end of the mounting frame 1, and an airbag 10 is provided between the connecting plate 9 and the electric telescopic seat 2. In detail, an air jet tube 11 is provided in communication with the airbag 10, and the jet end of the air jet tube 11 extends to be opposite to the rotating shaft 3. For example, along with the adhesive transfer direction of the electric telescopic seat 2, the connecting rod 4, the air jet tube 11 and the rotating shaft 3 are arranged in sequence. When the electric telescopic seat 2 transfers the adhesive, the airbag 10 will be squeezed between the connecting plate 9 and the electric telescopic seat 2, and then the gas in the airbag 10 can be sprayed to the tape, thereby generating positive pressure on the tape to assist the tape to adhere to the PCB board.

[0029] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
