Description

Technical Field

[0001] This utility model belongs to the field of circuit board equipment technology, and in particular relates to a circuit board marking and coding mechanism. Background Technology

[0002] With the development of modern technology, traditional inkjet marking methods are gradually being phased out. This is because inkjet marking requires direct contact with the product surface, which not only increases production costs but also makes the marks easily erasable and has a significant environmental impact. Conversely, laser marking technology is becoming the industry's preferred choice due to its unique advantages: it uses a non-contact marking method, causing no damage to the product; its environmentally friendly characteristics reduce the burden on the natural environment; laser marking also provides higher processing precision and durable marks that are not easily removed and have a longer lifespan; furthermore, this technology can improve processing efficiency. Therefore, laser marking technology occupies an increasingly important position in the marking industry.

[0003] For example, prior art CN211280262U discloses an automatic laser marking machine for printed circuit boards, including a frame and an electrical control box mounted on the frame. A carbon dioxide laser is installed at the front end of the electrical control box, and a conveyor belt is arranged below the carbon dioxide laser. A partition is installed on the surface of the conveyor belt, and a frame is installed on the outside of the conveyor belt. Support frames are installed at both ends of the frame. A discharge tube and a power supply are installed inside the carbon dioxide laser. An electrode is arranged inside the discharge tube, and the power supply is electrically connected to the electrode. A total internal reflection concave mirror is installed at one end of the discharge tube, and a reflecting flat mirror is installed at the other end of the discharge tube. A directional reflector is installed on one side of the reflecting flat mirror, and a focusing lens is installed at the bottom of the directional reflector. A nozzle is installed on the outside of the focusing lens.

[0004] Although existing technologies use laser marking to replace the original spraying and grinding marking, the shaping process and the marking process are carried out by two separate mechanisms. Due to the existence of two mechanisms, there are technical problems such as high space occupancy and low work efficiency. In addition, the existing marking mechanism equipment has very low adaptability to circuit boards of different sizes. Utility Model Content

[0030] like Figure 2 As shown, the shaping assembly 1 includes a pressure plate 100, an extrusion plate 101, and an extrusion plate driving member 102 connected to the extrusion plate 101. The pressure plate 100 and the extrusion plate 101 cooperate to extrude and shape the circuit board on the circuit board conveying assembly 3. The pressure plate 100 has a partially light-transmitting part for marking the circuit board with the laser of the laser marking assembly 2. Preferably, the pressure plate 100 is a light-transmitting plate that is entirely light-transmitting.

[0031] Furthermore, such as Figure 3 As shown, the extrusion plate drive component 102 includes a first support plate 103, a second support plate 104, a push rod 105, a lead screw nut 106, and a motor 108 connected to the lead screw 107. The first support plate 103 is fixedly installed and located above the second support plate 104. The push rod 105 and the lead screw nut 106 are fixedly installed on the second support plate 104. The push rod 105 passes through the first support plate 103, and the top end of the push rod 105 is fixedly installed on the bottom surface of the extrusion plate 101. The lead screw nut 106 is sleeved on the lead screw 107. The motor 108 connected to the lead screw 107 is located below the second support plate 104.

[0032] Furthermore, a first sliding part 109 is fixedly provided below the first support plate 103 in the vertical direction along the conveying direction of the circuit board. The first sliding part 109 can be of any structure. Preferably, the first sliding part 109 includes a slider disposed below the first support plate 103 and a fixed slide rail. The slider and the slide rail slide together to facilitate the position adjustment of the shaping component 1.

The guide post 110 passes through the second support plate 104, and the top end of the guide post 110 is fixedly installed on the bottom surface of the first support plate 103 to guide the movement of the extrusion plate 101.

[0034] Furthermore, the first support plate 103 and the second support plate 104 are respectively provided with sleeves that slide in cooperation with the push rod 105 and the guide post 110, in order to improve the service life of the push rod 105 and the guide post 110.

[0035] like Figure 4 As shown, the circuit board conveying assembly 3 includes two transmission parts 300, which are arranged side by side. The extrusion plate 101 is located between the two transmission parts 300 and is used to lift the circuit board to be shaped.

The tensioning wheel assembly 304 is sleeved on the conveyor belt 302, and the drive wheel 305 of the tensioning wheel assembly 304 of the two transmission units 300 is connected to the drive shaft of the same driving component, to ensure the synchronous transmission of the circuit board by the conveyor belt 302.

[0039] Working principle:

[0040] Defective circuit boards after inspection are sent to shaping assembly 1 via circuit board conveying assembly 3. Motor 108 drives lead screw 107 to rotate, causing motor 108 and the second support plate 104 to move upwards. Push rod 105 on the second support plate 104 pushes extrusion plate 101. Extrusion plate 101 cooperates with pressure plate 100 to extrude and shape the defective circuit boards. Simultaneously or after shaping, laser marking assembly 2 emits laser light, which passes through the light-transmitting part of pressure plate 100 to mark the circuit boards. When processing circuit boards of different sizes, the transmission part 300 of circuit board conveying assembly 3 can move along the second sliding part 301 to adjust the distance between the two transmission parts 300. Simultaneously, the extrusion plate 101 of shaping assembly 1 can move along the first sliding part 109 to keep it in the middle position between the two transmission parts 300, facilitating circuit board shaping.

[0041] Therefore, this utility model achieves reduced space occupancy by integrating the shaping component 1 and the laser marking component 2; it achieves marking while shaping by cooperating with the shaping component 1 and the laser marking component 2, thus improving work efficiency; and it enables shaping and marking of circuit boards of different sizes by adjusting the spacing of the circuit board conveying component 3 and the position of the shaping component 1.
