Creation Instructions (i) ^ Position-[Technical Field to which New Types belong] Machine-based creation is about a semi-automatic solder paste printing machine, which is more than 100% suitable for use with steel plates with a large range of printing patterns. ▲ ^, especially suitable for small batch, low cost and high efficiency production. Heart that the printing is too small

The brush machine installed in the steel sheet on page 5 is mostly used for small batch production processes. Therefore, the know-how of half a while, and some of the know-how transfer the substrates to be printed, but still made previously, and the low-auto tin semi-automatically gained a lot by manual presentation. The same product name may not be used in batches to reduce the single steel technology by only managing the production method.] Generally speaking, the cost of paste printing, solder paste printing, control technology, and different products are the same. The cost of paste printing is convenient. 'So the pattern is only opened in the veneer, and the development of conventional production or machine parts is usually complicated. The production process that requires complex names is the most common. The process is most common and can be simplified. Equipped with a matching set of crescent moon, especially the product, but the process is exhausting the brain as an example, the treatment of omission of the needle production process solder paste printing test simply set the belt master. For the special shipments, equipment juices to avoid most of the methods, the different industries and different types of brush patterns can be used. Most of the products are not high in the industry, and the production of fixtures is semi-automatic. It is a uniform production of steel. The reduction of steel requirements of traditional steel plates is also caused by the manufacturer's order, or even the cost of the solder paste printed steel plate, the printing method of the other plate, and the gradual interpretation of the printed empty plate may be connected, because all materials are high; Production size with small brush machine, it is not easy or uniform to dispose of a brush pattern, which is easy because of the cost of materials, M261957 IV. Creation instructions (2) And multiple substrates can be printed in the same process, which can increase production output and Increase productivity. Please refer to the first figure, which is a perspective view of a conventional semi-automatic solder paste printing machine.

The two sensors 3 1 a and 3 2 a installed on the conventional semi-automatic solder paste printing machine are used respectively for {测测 刀 2 1 a (or 2 2 a ) Whether it is in place or away depends on the size of the steel plate 40 a or the size of the printed pattern 4 3 1 a opened in the steel plate 40 a. The two sensors 3 1 a and 3 2 a need to be adjusted to an appropriate position. The scraper blade 2 1 a (or 2 2 a) can be walked until the printing pattern 4 3 1 a is completed; but because the pair of left and right scraper blades 2 1 a and 2 2 a are separated by a fixed predetermined distance d > (please (Refer to the third picture A), and the elastic piping 4 2 a of the steel plate 40 a has approximately the same width s > (see the third picture A), when the steel plate 4 a is opened because of the printed pattern 4 3 1 The range of a is so large that the predetermined distance g / reduction between the ® elastic piping 4 2 a and the printed pattern 4 3 1 a, when one of the scrapers 2 1 a (or 2 2 a) walks to reach the predetermined distance g > sensor 3 1 a (or 3 2 a) will cause the scraper 2 la (or 22a) to rise and another scraper 22a (or 2 1 a) to fall at the same time. The distance g > is not sufficient to cover the predetermined distance d > between the pair of left and right scrapers, and the falling scraper 2 2 a (or 2 1 a) will fall on its elastic bead 4 2 a, which is easy to make. Damage, reducing the service life of the steel plate 40 a. Please refer to the third diagram A to the third diagram F. The schematic diagram of the operation of the conventional semi-automatic solder paste printing machine j is shown; the two sensors 3 1 a and 3 2 a are positioned on the left and right sides, respectively, and the two sensors 3 1 a and 3 2 a are used to detect the robot arm 12 a holding the pair of left and right scrapers 21 a and 22 a, as shown in the third figure A.

Creation instructions (4) The printing range P 1 'in order to make sure that the printed picture is completely scraped when the right to the knife 2 2 a is turned left to back, the range d-of 4 3 1 a, and to avoid After the printed solder paste is collapsed and covered on the printed pattern 4 3 1 3, the right scraper blade 2 2 a must be dropped, and the steel plate 4 0a has the predetermined distance g / li, but the predetermined distance g / Insufficient to cover the predetermined distance d > between the pair of left and right scrapers 2 ia and 2 2 a, the left scraper 2 1 3 is bound to fall on the elastic piping 4 2 a; as shown in the third figure B, the left scraper 2 1 a continuously walks to the right after falling; as shown in Figures 3C and 3d, the right sensor 3 2 a is set to 1 to sense the height of the robot arm 1 2 a, and is set to a position that just makes the The left scraper 2 1 a falls at an appropriate position of the predetermined distance S > of the steel plate 40 a and cooperates with the control unit 1 3 a. When the sensor 3 2 a on the right side senses the robot arm 1 2 a, Immediately return the response signal to the control unit 1 3 a. The control unit 1 3 a causes the robot arm 1 2 a to stop moving, causes the left scraper 2 1 a to rise, and causes the right scraper 2 2 a to fall. Lower and the robot arm 1 2 a move to the left; as shown in Figures 3 and 3 F, the right scraper 2 2 a continues to move to the left 'until the left sensor 3 1 a senses the robot arm 1 2 a 'The robot arm 1 2 Γ stops moving, the right scraper 2 2 a is raised, the left scraper 2 1 a is dropped, and the robot arm 1 2 a is moved to the right'. After repeating this cycle, the left scraper 2 Please refer to P 1 and P 2 for the printing stroke of 1 a and the right scraper 2 2 a. Therefore, no matter whether one of the pair of left and right scrapers 2 1 a and 2 2 a is dropped, the elasticity of the steel plate 4 oa is unavoidably damaged; the edge 4 2 a ′ shortens the service life of the steel plate 40 a.

Page 8 M261957 IV. Creation instructions (5) When one of the knives 2 1 a and 2 2 a reaches the elastic piping 4 2 a of the steel plate 40 a, it walks to the printed pattern that needs to be scraped with solder paste 4 3 1 The distance of a is too long, it is easy to leave too much solder paste, not only wasting solder paste, but the problem that the residual solder paste is easily deteriorated, but also increases the frictional resistance between the scraper 2 1 a (or 2 2 a) and the steel plate 40 a, which affects The life of the scraper blade 2 1 a (or 2 2 a). The traditional solution is generally to increase the steel plate 40a. Since the width s > of the elastic piping 42a is approximately fixed, the predetermined distance g > can be lengthened to avoid the above problems. However, due to the aforementioned considerations of small batches and multiple product names, the usage rate of 40 a per steel plate is not high; and due to the difference in the range D / of the printed pattern 4 3 1 a, even if the steel plate 4 of the same size is used 0 a, also has a different predetermined distance g — when the predetermined distance g > is sufficiently large, the scraper blade 2 1 a (or 2 2 a) will not be pressed down to the elastic rim 4 2 a when it falls, then At this time, it is not necessary to increase the size of the steel plate 40 a. Therefore, the method of increasing the size of the steel plate 40 a in the same product is only to increase the cost and management burden of the steel plate. The reason is that the creator feels the above-mentioned shortcomings. It is an intensive study and the application of theories to propose a rational design and effectively improve the above-mentioned original creations.
