Description

Technical Field

[0001] The invention relates to the technical field of plug-in machines, and in particular to an improved vertical plug-in machine based on a pin bending structure. Background Art

[0002] An insertion machine is a machine that automatically installs taped electronic components on printed circuit boards according to a program. The traditional electronic assembly industry mainly relies on workers to insert electronic components on circuit boards. Since the machines began to be mass-produced, the speed of manual insertion has been slow and the defects of poor workmanship have been exposed. Using an insertion machine to automatically install electronic components on circuit boards can save labor costs and improve the level of insertion technology.

[0003] Before inserting the pins of electronic components into the circuit board, the traditional vertical plug-in machine needs to position and install the circuit board through positioning tools such as positioning fixtures or jigs, and then transport it to the plug-in station of the plug-in machine. In order to ensure the positioning accuracy of the circuit board, the positioning size of the positioning tool needs to be consistent with the size of the circuit board, which makes it difficult for the circuit board positioning tool to adapt to different positioning sizes and has poor versatility.

[0063] See also Figure 1-Figure 5 , the principle and advantages of the improved vertical plug-in machine based on the pin bending structure:

[0064] First, the positioning pins 33 are adjusted according to the spacing of the positioning holes of the circuit board. During the adjustment, the circuit board is placed on the top of the positioning pins 33 so that the positioning pins 33 provide preliminary support for the circuit board. Then, the precision screw rod 34 on the outside of the electric slide frame 3 is rotated to drive the screw rod sleeve 35 to move, so that the screw rod sleeve 35 drives the wedge-shaped tooth block 37 to move through the fixed block 36, and then the positioning pins 33 are driven to move along the slide hole A32 through the wedge-shaped tooth block 37. When the positioning pins 33 move into the positioning holes of the circuit board, the positioning pins 33 are automatically inserted into the positioning holes of the circuit board. Then, the precision screw rod 34 is continued to be rotated until all the positioning pins 33 are located in the positioning holes of the circuit board. The circuit board will fall into the positioning hole at this time, and the positioning hole and the positioning pin 33 of the circuit board will be positioned under the action of the conical sleeve 312, so that the positioning pin 33 is located at the center of the positioning hole of the circuit board, and then the circuit board on the top of the support table 31 is driven to move into the housing 12 by the electric slide frame 3, and at the same time, the neatly arranged electronic components are input into the housing 12 by the electronic component conveying equipment installed on the mounting frame 18, so that the plug-in assembly 2 inside the housing 12 inserts the electronic components transported by the conveying equipment on the circuit board; it should be noted that before the insertion, the U-shaped plate 15 is pushed by the electric push rod A14 The U-shaped plate 15 pushes the lifting plate 13 to approach the counterweight block 311 until the counterweight block 311 is pushed up a certain distance, so that the counterweight block 311 drives the intermediate gear 39 to rotate through the vertical gear block 310, and drives the wedge-shaped gear block 37 to slide along the guide rail B38 through the intermediate gear 39. Since the inclined surface of the wedge-shaped gear block 37 moves along the tangential direction of the intermediate gear 39, the positioning pin 33 moves downward as the wedge-shaped gear block 37 moves downward, and the positioning pin 33 approaches the inner wall of the positioning hole of the circuit board, so that the positioning pin 33 fixes the circuit board in place. At the same time, when the positioning pin 33 descends, it drives the connecting sleeve 31 through the sliding sheet 331 4 descends together and slides horizontally along the inner side of the connecting sleeve 314 to ensure the downward movement trajectory of the positioning pin 33, and at the same time, the connecting sleeve 314 drives the conical sleeve 312 to be located at the bottom of the support platform 31, releases the support for the circuit board, and makes the circuit board be located on the top of the support platform 31 for insertion, so as to ensure that the distance between the bending component 4 and the circuit board remains unchanged during the insertion; after the insertion, the circuit board is driven by the electric slide frame 3 to move out of the interior of the housing 12 for unloading, at which time the other electric slide frame 3 has completed unloading, and then the two electric slide frames 3 move in the opposite direction, so that the new circuit board is located inside the housing 12 for insertion processing.

[0065] The advantage is that by setting the precision screw rod 34 to adjust the distance between the positioning pins 33 on both sides, the circuit board can be placed on the top of the positioning pin 33 for support before unloading, and then the electric slide frame 3 is adjusted to move. When the electric slide frame 3 is inserted into the positioning hole of the circuit board, the positioning hole is supported by the conical sleeve 312 on the outside of the positioning pin 33, so that the positioning pin 33 and the center of the circuit board positioning hole are positioned, and finally the circuit board and the plug-in station of the plug-in component 2 are positioned by the positioning pin 33; and after the position of the positioning pin 33 is determined, when the circuit board is unloaded, since the diameter of the positioning pin 33 is smaller than the inner diameter of the circuit board positioning hole, the circuit board can be sleeved on the outside of the positioning pin 33. Before plug-in, the lifting plate 13 is raised to drive the positioning pins 33 away from each other and press against the inner wall of the positioning hole to realize the positioning and fixation of the circuit board. On this basis, the plug-in component 2 is plugged into the inside of the casing 12.

[0066] See also Figure 1-Figure 10 After inserting the pins of electronic components into the circuit board, the traditional vertical plug-in machine will bend the pins through the bending structure at the bottom of the circuit board to meet the plug-in requirements of the electronic components; however, in order to reduce the space occupied by the bending structure at the bottom of the circuit board and prevent the surrounding electronic component pins from being affected, the bending structure is usually two fixed-size clamps. For the current 4-pin, 8-pin and 16-pin double-row pin electronic components, as the number of pins increases, the width requirements of the clamping blocks in the bending direction are different, and it is difficult to quickly bend multiple pins synchronously during the plug-in, and multiple bending actions are required after one plug-in action, resulting in a decrease in the plug-in efficiency of the plug-in machine.

[0067] In order to overcome the above-mentioned defects, the bending assembly 4 in the improved vertical insertion machine based on the pin bending structure of the present application drives the pulley 419 to rotate through the motor B422 on the outside of the bending block 48 before bending, so that the pulley 419 synchronously drives the two adjusting disks 410 to rotate through the belt 421. Every time the adjusting disk 410 rotates a certain angle, the guiding inclined surface at one end of the arc plate 413 will be driven to approach the bottom of the ball head rod 414, so that the guiding inclined surface guides the ball head rod 414 to the top of the arc plate 413, and the arc plate 413 is used to lift the ball head rod 414, so that the ball head rod 414 pushes the corresponding sliding plate 411 to slide upward on the inside of the sliding sleeve 417, thereby making the bending portion 412 at the top of the sliding plate 411 aligned with the bending part 41. It is worth mentioning that as the rotation angle of the adjusting disk 410 increases, the sliding plates 411 close to the two sides of the bending part 41 will be driven to slide first, and so on, and the bending of the bending part 41 can be gradually extended. Width, realizes the bending work of multiple groups of double-row pins, so that when the mechanical clamp 212 is inserted, the bending component 4 can quickly bend the pins; it should be noted that when the bending piece 41 is bent, the electric push rod D49 drives the bending block 48 to slide on the top of the rotating table 47, and the two bending blocks 48 slide relative to each other to drive the bending piece 41 to realize the bending action. At this time, the distance between the two adjustment disks 410 is reduced, causing the belt 421 to rotate. In order to prevent the belt 421 from falling off, a tensioning wheel 420 is arranged on the top of the other bending block 48 to tension the belt 421 during the bending process. Since the tensioning structure and principle of the tensioning wheel 420 adopt the existing technology, they are not repeated here. For different plug-in angles, the motor A44 drives the gear A45 to rotate, so that the gear A45 drives the rotating table 47 on the top of the gear B46 to rotate, so as to adjust the bending direction of the bending piece 41 to ensure the efficiency of the bending work.

[0068] It is worth mentioning that the above bending method has the following advantages:

[0069] Advantage 1: The bending width of the bending piece 41 can be adjusted according to the number of double-row pins of the electronic component to ensure that when the plug-in assembly 2 is plugged in, the pins are quickly bent under the action of the mechanical clamp 212 clamping the electronic component, thereby ensuring the bending efficiency of the double-row pins.

[0070] Advantage 2: When adjusting the bending width range of the bending part 41, the sliding plate 411 is driven to slide and rise by rotating the adjusting disk 410, so that the bending portion 412 at the top of the sliding plate 411 is flush with the bending part 41, thereby adjusting the bending range of the bending part 41. When adjusting, the bending portions 412 close to both sides of the bending part 41 are slid and aligned first to ensure the neatness after adjustment and alignment.
