Description

Technical Field

[0001] The present invention relates to the technical field of chip mounters, and in particular to an automatic chip mounter for electronic components. Background Art

[0002] A fully automatic chip mounter is a device used to achieve high-speed and high-precision fully automatic placement of components. It is the most critical and complex device in the entire SMT production. The chip mounter is the main device in the SMT production line. The chip mounter has developed from the early low-speed mechanical chip mounter to a high-speed optical centering chip mounter, and is developing towards multi-function and flexible connection modularization.

[0003] The chip mounter works by moving the mounting head to accurately place the surface-mounted components on the PCB pads. The mounting head, through intelligent control, sucks the components in the feeder tray and accurately places them on the PCB pads. After placement, the mounting head needs to move to the feeder tray area again to suck the components and then place the components on the PCB pads.

[0004] In the existing chip mounter, there is a feeder tray. The feeder tray contains components for the mounting head to suck and then perform the chip mounting work on the PCB pads. If the components placed in the feeder tray are used up, it is necessary to stop the operation of the chip mounter, and then replace the feeder tray or replenish the components in the feeder tray. This replenishment method is extremely troublesome, wastes production time, increases the time cost, and reduces the production efficiency.

[0005] In view of this, the present invention provides an automatic chip mounter for electronic components to solve the above technical problems. Summary of the Invention

Specific embodiments

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] The embodiment of the present invention provides an automatic mounter for electronic components, which solves the technical problem in the prior art that in the long-term operation of the mounter, if the components placed in the loading box (tray) are used up, it is necessary to frequently replace the loading box (tray), and during the process of replacing the loading box or replenishing the components in the tray, the equipment must stop running. This replacement (replenishment) method is extremely troublesome, wastes production time, and reduces production efficiency;

[0053] The technical solution in the embodiment of the present invention to solve the above technical problem is generally as follows: by adding components such as a feeding mechanism, cylinder 2, conveying rail, slide rail, and cylinder 1 to the equipment, when all the components in the loading box are used up, start cylinder 1 to push the topmost loading box (the internal components have all been used) onto the slide rail, and make it slide down along the slide rail to complete the recycling. Then start cylinder 2 to push the stacked loading boxes upward, and transport the brand-new loading box to the topmost position for the mounter to continue working, reducing labor costs and improving production efficiency;

[0054] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0055] Please refer to Figures 1 to 6 , the present invention provides a technical solution:

[0056] An automatic component mounter, comprising a base 11, and an upper plate 12 is fixedly installed on the upper end surface of the base 11;

[0057] A mounter main body 7 is arranged on the upper end surface of the upper plate 12;

[0058] The interior of the base 11 is designed to be hollow;

[0059] A feeding mechanism 2 is arranged on the front side inside the base 11.

[0060] During operation, the moving mounting head in the mounter main body 7 performs the chip mounting work on the upper plate 12 and picks up components from the tray. When all the components in the tray are used up, the feeding mechanism 2 is operated, and the feeding mechanism 2 can perform fully automatic feeding work, greatly saving labor costs, improving production efficiency, and reducing time costs.

[0061] As an embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the feeding mechanism 2 includes a first rod 21, a supporting movable block 22, and a second cylinder 24; a second cylinder 24 is fixedly installed on the front side of the lower end inside the base 11; two groups of supporting columns 4 are fixedly installed at positions on the left and right sides of the second cylinder 24 at the lower end inside the base 11; a top block 241 is fixedly installed at the output end of the second cylinder 24; the first rods 21 are rotatably installed between the two groups of supporting columns 4 at equal intervals and evenly distributed; the supporting movable blocks 22 are rotatably installed on the front and rear sides of the first rod 21; a conveying rail 1 is arranged above the second cylinder 24; the end of the conveying rail 1 extends above the top block 241; loading boxes 6 are transported on the conveying rail 1 at equal intervals and evenly distributed; the loading boxes 6 are placed on the upper end surfaces of the supporting movable blocks 22, and one end of the supporting movable block 22 far from the second cylinder 24 is designed as a large inverted triangle and the other end is designed as a small inverted triangle; a limiting groove 221 is opened on the upper end surface of the end of the supporting movable block 22 designed as a small inverted triangle; a fixing rod 23 is fixedly installed at a position passing through the limiting groove 221 between the two groups of supporting columns 4, and a limiting rod 25 in an L shape is fixedly installed on the outer surface of the supporting column 4 on the side close to the second cylinder 24; the L-shaped notch of the limiting rod 25 matches the corner of the loading box 6, and the upper width of the loading box 6 is greater than the distance between a pair of left and right supporting movable blocks 22; the width of the top block 241 is less than the width of the conveying rail 1, and limiting rings 8 are arranged at positions on the front and rear sides of the supporting movable block 22 on the outer circumferential surface of the first rod 21; a limiting screw 81 is threadedly connected to the upper end of the limiting ring 8; the limiting ring 8 is fixedly installed on the outer circumferential surface of the first rod 21 through the limiting screw 81, and a rubber sleeve 222 is bonded to the outer surface of the end of the supporting movable block 22 designed as a large inverted triangle; the limiting rod 25 is made of hard rubber material.

[0062] During operation, loading boxes 6 (trays) filled with components are evenly placed at equal intervals on the conveying rail 1 (the conveying rail 1 is not fully shown). The loading box 6 is conveyed by the conveying rail 1 to the upper part of the second cylinder 24 (the conveying rail 1 is manually controlled by the console or programmed in advance). When the loading box 6 moves to the upper part of the second cylinder 24, the second cylinder 24 is started, and the output end of the second cylinder 24 moves upward, driving the top block 241 to move upward. The upward movement of the top block 241 will push the loading box 6 located above the top block 241 upward. The loading box 6 moves upward under the thrust. The upper half of the loading box 6 will collide with the large inverted triangle end of the supporting movable block 22. The loading box 6 squeezes the supporting movable block 22 along the inclined plane and flips it upward. When the two are completely separated and no longer collide, the supporting movable block 22 resets. Then the second cylinder 24 stops operating and no longer pushes the loading box 6. The loading box 6 stops moving. The upper half of the loading box 6 will be supported by the upper end of the supporting movable block 22. Since the fixing rod 23 passes through the limiting groove 221 in the small inverted triangle of the supporting movable block 22 and the fixing rod 23 is fixedly installed with the supporting column 4, the fixing rod 23 will limit the supporting movable block 22 from being squeezed by the loading box 6 and flipping downward, thus completing the support of the loading box 6 and enabling the loading box 6 to move to the upper end of the supporting movable block 22 on the upper layer. At the same time, limiting rings 8 fixedly connected by limiting screws 81 are arranged on both the front and rear sides of the supporting movable block 22. The limiting rings 8 are used to fix the supporting movable block 22 to prevent deformation and offset during long-term operation. At the same time, if a component is damaged, the limiting screw 81 can be unscrewed and the limiting ring 8 can be removed for replacement, without replacing the entire first rod 21 and the components on the first rod 21, saving maintenance costs. The function of the limiting rod 25 is to prevent the loading box 6 from offsetting during the upward movement, and the limiting rod 25 is made of rubber to reduce the collision wear with the loading box 6; a rubber sleeve 222 is glued to the large inverted triangle end of the supporting movable block 22, also reducing the collision wear with the loading box 6. When the next loading box 6 moves to the upper part of the second cylinder 24, the second cylinder 24 is started again. Similarly, the second cylinder 24 pushes the bottom loading box 6 upward. It should be noted that the height of the loading box 6 is the same as the height between each layer of supporting movable blocks 22 and the distance of each movement of the second cylinder 24. During the upward movement of the bottom loading box 6, it will push the upper loading box 6. The movement process is the same as above, and it repeats until the top loading box 6 moves to the top supporting movable block 22, which is convenient for the pick-and-place machine to grab the components in the loading box 6 for chip placement work.

[0063] As an embodiment of the present invention, as Figure 2 and Figure 3As shown, a first cylinder 3 is fixedly installed on the inner surface of the front end of the upper plate 12 at a position behind the uppermost loading box 6; the first cylinder 3 is at the same height as the lower half of the uppermost loading box 6; a slide rail 5 is arranged at a position below the front side of the upper half of the uppermost loading box 6, and the slide rail 5 is designed as a slowly downward arc track; a connecting rod 9 is fixedly connected between the ends of the large inverted triangle ends of the uppermost support movable block 22; a leather sleeve made of rubber is glued to the end of the output end of the first cylinder 3; the upper end of the limit rod 25 extends below the uppermost loading box 6, and the lower end extends above the top block 241 of the lowermost loading box 6.

[0064] During operation, based on the above embodiment, when all the components in the uppermost loading box 6 are used up, the first cylinder 3 is driven, and the output end of the first cylinder 3 will push the uppermost loading box 6, causing it to slowly move onto the slide rail 5 (the slide rail 5 is not fully drawn), and then slide down along the slide rail 5 for recycling. A connecting rod 9 is fixedly connected between the ends of the large inverted triangle ends of the uppermost support movable block 22 to prevent the loading box 6 from falling when it is pushed, so that the loading box 6 has an external force to support it throughout the process. The upper end of the limit rod 25 extends below the uppermost loading box 6, enabling the loading box 6 to smoothly move onto the slide rail 5. A leather sleeve made of rubber is glued to the end of the output end of the first cylinder 3 to reduce the wear caused by collisions and lower the maintenance cost. After the uppermost loading box 6 slides down through the slide rail 5, the second cylinder 24 is driven to push the next layer of loading box 6 to the top, which facilitates the smooth operation of the pick-and-place machine, saves a large amount of time and labor costs, and improves the production efficiency.

[0065] Working principle: On the conveying rail 1 (the conveying rail 1 is not fully drawn), there are evenly placed loading boxes 6 (trays) filled with components at equal intervals. The loading boxes 6 are conveyed to the upper part of the second cylinder 24 through the conveying rail 1 (the conveying rail 1 is manually controlled by the console or programmed in advance). When the loading box 6 moves to the upper part of the second cylinder 24, the second cylinder 24 is started, and the output end of the second cylinder 24 moves upward, driving the top block 241 to move upward. The upward movement of the top block 241 will push the loading box 6 located above the top block 241 upward. The loading box 6 moves upward under the thrust. The upper half of the loading box 6 will collide with the large inverted triangle end of the supporting movable block 22. The loading box 6 squeezes the supporting movable block 22 along the inclined plane and flips it upward. When the two are completely separated and no longer collide, the supporting movable block 22 resets. Then the second cylinder 24 stops operating and no longer pushes the loading box 6. The loading box 6 stops moving. The upper half of the loading box 6 will be supported by the upper end of the supporting movable block 22. Since the fixing rod 23 passes through the limiting groove 221 in the small inverted triangle of the supporting movable block 22 and the fixing rod 23 is fixedly installed with the supporting column 4, the fixing rod 23 will limit the supporting movable block 22 from being squeezed by the loading box 6 and flipping downward, thus completing the support of the loading box 6 and enabling the loading box 6 to move to the upper end of the supporting movable block 22 on the upper layer. At the same time, limiting rings 8 fixedly connected by limiting screws 81 are arranged on both the front and rear sides of the supporting movable block 22. The limiting rings 8 are used to fix the supporting movable block 22 to prevent deformation and deviation during long-term operation. At the same time, if a component is damaged, the limiting screw 81 can be unscrewed and the limiting ring 8 can be removed for replacement without replacing the entire first rod 21 and the components on the first rod 21, saving maintenance costs. The function of the limiting rod 25 is to prevent the loading box 6 from deviating during the upward movement, and the limiting rod 25 is made of rubber to reduce the collision wear with the loading box 6;One end of the large inverted triangle supporting the movable block 22 is adhesively connected with a rubber sleeve 222, which also reduces the collision and wear between the rubber sleeve and the loading box 6. When the next loading box 6 moves above the second cylinder 24, the second cylinder 24 is started again. Similarly, the second cylinder 24 pushes the bottom loading box 6 upward. It should be noted that the height of the loading box 6 is the same as the height between each layer of supporting movable blocks 22 and the distance of each movement of the second cylinder 24. During the upward movement of the bottom loading box 6, it will push the upper loading box 6. The movement process is the same as the above, and it repeats until the top loading box 6 moves onto the top supporting movable block 22, which is convenient for the pick-and-place machine to grab the components in the loading box 6 for soldering work. When all the components in the top loading box 6 are used up, the first cylinder 3 is driven. The output end of the first cylinder 3 will push the top loading box 6, making it slowly move onto the slide rail 5 (the slide rail 5 is not fully drawn), and then slide down along the slide rail 5 for recycling. A connecting rod 9 is fixedly connected between the ends of the large inverted triangle of the top supporting movable block 22 to prevent the loading box 6 from falling when it is pushed, so that the loading box 6 is supported by an external force throughout the process. The upper end of the limiting rod 25 extends below the top loading box 6, enabling the loading box 6 to move onto the slide rail 5 smoothly. The end of the output end of the first cylinder 3 is adhesively connected with a rubber leather sleeve to reduce the wear caused by collision and lower the maintenance cost. After the top loading box 6 slides down through the slide rail 5, the second cylinder 24 is driven to push the next layer of loading box 6 to the top, which is convenient for the pick-and-place machine to work smoothly, saving a large amount of time and labor costs and improving production efficiency.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
