Description

Technical Field

[0001] The utility model relates to the technical field of SMT processing, in particular to an SMT complete line equipment. Background Art

[0002] SMT complete line equipment includes printers, dispensing machines, placement machines, reflow ovens and wave soldering machines, etc. In addition, there are also testing, rework, cleaning, drying and material storage equipment, etc. According to the degree of automation and scale, SMT production lines can be divided into fully automatic and semi-automatic production lines, as well as large, medium and small SMT production lines.

[0003] The Chinese patent with publication number CN220160389U provides an SMT patch dispensing machine. When the device is working, the first electric telescopic rod is extended so that the pipe can touch the device normally. When the pipe touches the device, the pipe drives the slide plate to move upward to shorten the spring. When it rises to a certain position, the convex tube will push open the baffle. At this time, the colloid will flow normally from the inside of the convex tube into the inside of the pipe, so that the colloid can be normally applied to the device. When the first electric telescopic rod is contracted, the fixed column will rise. At this time, the pipe is removed from the device. Through the reset of the spring, the slide plate and the convex tube are returned to the normal position. The baffle, which is no longer affected by the convex tube, will normally close the inner hole, which can effectively prevent the continuous outflow of the colloid and avoid the waste of the colloid.

[0004] In addition to the above-mentioned advantages, this utility model patent still has some shortcomings: First, since the device of the existing dispensing machine is directly placed on the automatic dispensing machine and fixed by its own gravity, the device is easy to move when the automatic dispensing machine is dispensing glue on the device. At this time, the dispensing effect of the device is easily affected, thereby reducing the dispensing efficiency of the device. Second, during the dispensing process of the existing dispensing machine, the dispensing head of the dispensing machine will have drawing and tailing phenomena, which will affect the quality of dispensing, affect the final effect of the product, and increase the later cost.

[0025] In this embodiment, please refer to Figure 2 A clamping groove is provided on the inner side of the clamping strip 46, and a rubber pad 461 is provided on one side of the inner wall of the clamping groove, which is conducive to fixing the product in the clamping groove after the two clamping strips 46 are brought close to each other. The rubber pad 461 is provided to protect both ends of the product to avoid damage to the product due to excessive pressure.

[0026] In this embodiment, please refer to Figure 2 A slide groove 411 is respectively provided on both sides of the inner wall of the fixed frame 41, and a slide bar 421 is fixedly connected to the contact surface between the movable bar 42 and the fixed frame 41. The inner wall of the slide groove 411 and the outer side of the slide bar 421 are adapted to each other, which is beneficial when the movable bar 42 moves along the inner wall of the fixed frame 41.

[0028] In this embodiment, please refer to Figure 4 The inner wall of the fixed sleeve 51 and the outer edge of the positioning plate 52 have an interference fit, the inner wall of the fixed sleeve 51 and the outer edge of the shift plate 53 have a transition fit, and the corresponding surfaces of the positioning plate 52 and the shift plate 53 have a transition fit, which is beneficial to prevent the colloid from passing through the gap between the fixed sleeve 51, the positioning plate 52, and the shift plate 53, thereby affecting the normal dispensing of the equipment.

[0029] Working principle of this utility model:

[0030] Step 1, in the utility model, by starting the second motor 7, the second motor 7 provides power to control the rotation of the driving shaft 44, and the rotation of the driving shaft 44 drives the driving gear 43 to rotate. Since the outer edge of the driving gear 43 is meshed with the corresponding surfaces of the two movable bars 42, by controlling the driving gear 43 to rotate counterclockwise, the two movable bars 42 can be driven to move toward each other. Driven by the two movable bars 42, the two linkage frames 45 drive the two clamping bars 46 to move closer to each other. After the distance between the two clamping bars 46 gradually decreases, the product can be clamped in the clamping groove of the clamping bar 46, so that the product is successfully fixed under the glue nozzle 3. When the product completes the dispensing process, according to the above principle, by controlling the driving gear 43 to rotate clockwise, the two clamping bars 46 can be separated from each other, and the clamping and fixing of the product can be stopped, so that the product can be removed;

[0031] Step 2, in the utility model, by starting the first motor 6, the first motor 6 is used to give power to control the power rod 57 to rotate, and the rotation of the power rod 57 drives the second bevel gear 56 to rotate. Since the outer edge of the second bevel gear 56 is meshed with the outer edge of the first bevel gear 55, when the second bevel gear 56 rotates, it drives the first bevel gear 55 to rotate, and the rotation of the first bevel gear 55 drives the shift plate 53 to rotate along the inner wall of the fixed sleeve 51. When the shift plate 53 rotates, the overlapping area of ​​the flow opening 54 opened on its surface and the flow opening 54 opened on the surface of the positioning plate 52 changes. When the overlapping area of ​​the two flow openings 54 gradually becomes smaller, the inner diameter of the glue nozzle 3 becomes smaller, thereby increasing the pressure of the glue nozzle 3 when dispensing glue. When the overlapping area of ​​the two flow openings 54 gradually becomes larger, the dispensing inner diameter of the glue nozzle 3 becomes larger, thereby reducing the pressure during dispensing glue. Therefore, the dispensing glue pressure can be flexibly adjusted according to product requirements to avoid the phenomenon of drawing and tailing in dispensing glue.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. The utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
