Description

Technical Field

[0001] The invention relates to the field of PCB printing and production, and in particular to a single-guide movable printing table and a screen printer. Background Art

[0002] With the development of science and technology, printed circuit boards (PCBs) are widely used in military, communications, medical, electric power, automobiles, industrial control, smart phones, wearables and other high-tech fields. As an important electronic component, PCBs are the support of electronic components. Due to its important role in the field of electronic components, it is called "electronic aircraft carrier" by many people. Therefore, the production technology level of PCBs has gradually become an important indicator to measure the scientific and technological level of a country.

[0003] With the rapid development of IT industry and electronic equipment manufacturing invested by countries around the world in China, PCB companies from all over the world have also made large-scale investments in China. China's PCB industry has experienced more than 20 years of rapid development from the mid-to-late 1980s to the present. It has gone through three development stages with state-owned economy, Sino-foreign joint ventures and wholly foreign-owned enterprises as the mainstream. It has become a world-class scale, and its output and output value are among the best in the world.

[0004] After decades of development, the PCB industry has become a global industry. In recent years, the output value of the global PCB industry accounts for more than 1 / 4 of the total output value of the electronic component industry. It is the largest industry in the electronic component sub-industry and occupies a unique position. As the new generation of electronic products requires printed circuit boards with higher density and more stable performance, printed circuit boards are gradually moving towards high density, high integration, fine lines, small apertures, and large capacity. With the development of thinness and lightness, the technical content and complexity are constantly increasing, and the market demand for high-precision printing equipment will continue to increase.

[0005] At present, the environmental and resource issues and sustainable development issues of the PCB industry have been placed at an unprecedented strategic height. The development of China's PCB industry must strengthen governance and put it on the circular economy track of clean production, so that the PCB industry can become a resource-saving and environmentally friendly industry. Therefore, PCB companies must actively face this situation, accelerate technological innovation and industrial revolution in traditional PCB production, and truly achieve energy conservation and emission reduction, and even pollution-free production.

[0023] The first base plate 101 is fixedly connected to the slider 3 and is arranged on the guide rail 2. The slider 3 can drive the first base plate 101 to slide freely. The first mounting plate 102 is fixedly arranged on the first base plate 101. The first guide rail 103 is arranged on the first mounting plate 102. The first slider 104 is arranged on the first guide rail 103 and can slide freely. The bearing seat 105 is arranged on the first slider 104. The screw nut 107 is arranged on the bearing seat 105. The screw 106 cooperates with the screw nut 107 to move. A pulley is arranged at the first end of the screw 106. A mobile printing table 110 is arranged at the second end of the screw 106. The lifting motor 109 controls the first pulley 108 symmetrically arranged in pairs through a synchronous belt, thereby driving the screw 106 to rotate. The rotation of the screw 106 drives the mobile printing table 110 to rise and fall freely.

[0024] The discharge platform 200 includes a second base plate 201, a second mounting plate 202, a guide shaft 203, a guide shaft sleeve 204, a cylinder 205, and a movable discharge platform 206; the guide shaft 203 and the guide shaft sleeve 204 are symmetrically arranged in pairs; the second base plate 201 is fixedly connected to the slider 3 and is arranged on the guide rail 2, and the slider 3 can drive the second base plate 201 to slide freely on the guide rail 2, and the second mounting 202 is arranged on the second base plate 201 through studs, and the guide shaft 203 and the guide shaft sleeve 204 are arranged in coordination and symmetrically arranged in pairs at both ends of the second mounting plate 202, the cylinder 205 is arranged on the second mounting plate 202, and the cylinder 202 drives the guide shaft 203 to rise and fall freely, and the movable discharge platform 206 is arranged at the end of the guide shaft 203.

[0025] By providing a single-track movable printing table, the superposition of the resistance of the slider during the movement of the printing table 100 is reduced, so that the printing table can be quickly prepared and positioned, achieving high-quality printing effects.

[0026] A connecting plate 301, a second pulley 302 and a driving motor 303 are arranged between the printing table 100 and the discharge table 200. The connecting plate 301 connects the first base plate 101 and the second base plate 201. The printing table 100 and the discharge table 200 are connected as a whole through the connecting plate 301. A synchronous belt connecting plate 304 is arranged on the connecting plate 301. The second pulley 302 and the driving motor 303 are arranged on the middle plate 1.

[0029] The table top of the movable discharging table 206 is a frosted layer, which increases the friction between the product and the table top during the discharging process and prevents the product from slipping.

[0030] A buckle is provided on the table of the mobile printing body 110, through which the product to be printed is clamped in during the working process, thereby preventing the product to be printed from falling off.

[0031] The single-track mobile printing table workflow of the present invention is as follows:

[0032] The driving motor 303 drives the printing table 100 and the discharging table 200 to the right end of the guide rail 2, and materials are loaded on the printing table 100. After loading is completed, the driving motor 303 drives the printing table 100 to the printing position for printing. After printing is completed, the product is lifted, and the driving motor 303 drives the printing table 100 and the discharging table 200 to the right end of the guide rail 2. The discharging table 200 receives the lifted product, and the printing table 100 loads materials. Then, the driving motor 303 drives the printing table 100 and the discharging table 200 to the printing position for printing, and the discharging table 200 performs the discharging action.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
