Description

Technical Field

[0001] The invention relates to the technical field of circuit board processing, and in particular to a copper column locking and rubber particle buckling device. Background Art

[0002] In some electronic products, copper pillars and colloids are typically installed on the circuit board to ensure a secure connection between the circuit board and the outer casing. These copper pillars and colloids allow the circuit board to be connected to the outer casing. Furthermore, the colloids can be used to prevent static electricity, reducing the effects of static electricity on the circuit board and electronic components, thereby improving the stability and reliability of the electronic product. In the prior art, an operator would hold a copper pillar and insert its threaded end into a mounting hole on the circuit board. The operator would then tighten a nut onto the threaded end of the copper pillar to secure the copper pillar to the circuit board, completing the locking installation of the copper pillar. The operator would then insert the snap-on end of the colloid into another mounting hole on the circuit board, snapping the colloid onto the circuit board to complete the snap-on installation of the colloid. After the copper pillars and colloids are installed, the operator would then proceed to the subsequent process of encasing the circuit board. This method of manually installing the copper pillars and colloids is slow and reduces the efficiency of copper pillar and colloid installation. Summary of the Invention

[0071] It should be explained that in the embodiments of the invention, the spring nut is a specially designed nut used to provide an additional anti-loosening function. It is usually used in equipment or structures that need to be frequently disassembled or in a vibrating environment to ensure that bolts or threaded connections will not loosen easily. The working principle of the spring nut is that through the spring structure, when subjected to vibration or external force, the spring will generate a reverse torque to prevent the nut from loosening on its own. The spring nut consists of a hexagonal nut and a spring. The edge of the spring is provided with a circle of serrations. The serrated edge can increase the friction between the spring and the contact surface to improve the locking effect and prevent the spring nut from loosening.

The adjusting block 260 can be slidably connected to the limit block 250 in the left and right directions. A second limiting groove 261 and an inclined guide groove 262 are opened on the adjusting block 260. The second limiting groove 261 is connected to the left end of the conveying groove 292 through the inclined guide groove 262. The two opposite side walls of the inclined guide groove 262 are both inclined surfaces. The wall gradually shrinks from right to left and is respectively connected with the two opposite side walls of the second limiting groove 261. The distance between the two opposite side walls of the second limiting groove 261 is equal to the distance between the two opposite side surfaces of the hexagonal nut of the spring nut. The first linear cylinder 210 can drive the adjustment block 260 to move rightward so that the two opposite side walls of the inclined guide groove 262 can abut against the hexagonal nut of the spring nut and drive the spring nut to rotate, and make the hexagonal nut of the spring nut fit the inner wall of the second limiting groove 261, so that the line between the two opposite vertices of the hexagonal nut of the spring nut is parallel to the left and right direction.

[0075] refer to Figure 10 The line between point a and point b in the figure is the line between the two opposite vertices of the hexagonal nut of the spring nut, and s in the figure is the distance between the two opposite side surfaces of the hexagonal nut of the spring nut.

[0076] As can be understood, the linear vibration track 291 conveys multiple spring-cage nuts from right to left. Because the bottom wall of the conveying trough 292 is higher than the bottom wall of the first limiting groove 251, the leftmost spring-cage nut in the conveying trough 292 can fall into the first limiting groove 251, where the inner wall of the first limiting groove 251 can abut against the spring of the spring-cage nut. After the spring-cage nut falls into the first limiting groove 251, the first linear cylinder 210 drives the adjustment block 260 to move rightward, closer to the linear vibration track 291. During the movement of the adjustment block 260 to the right, the two opposite side walls of the inclined guide groove 262 will abut against the hexagonal nut of the spring nut, and the spring of the spring nut will abut against the straight vibration track 291. The spring nut in the first limiting groove 251 begins to vibrate. Since the two opposite side walls of the inclined guide groove 262 gradually shrink from right to left, the two opposite side walls of the inclined guide groove 262 can drive the hexagonal nut of the spring nut to rotate, that is, drive the entire spring nut to rotate. Because the distance between the two opposing inner walls of the second limiting groove 261 is equal to the distance between the two opposing side surfaces of the hexagonal nut of the spring nut, and the two opposing side walls of the inclined guide groove 262 respectively connect with the two opposing inner walls of the second limiting groove 261, the spring nut stops rotating when it is at the connection between the second limiting groove 261 and the inclined guide groove 262. As the adjustment block 260 continues to move rightward, the hexagonal nut of the spring nut moves into the second limiting groove 261 and fits against the inner wall of the second limiting groove 261, completing the positioning of the spring nut so that the line connecting the two opposing vertices of the hexagonal nut of the spring nut is parallel to the left and right directions. Finally, the first linear cylinder 210 drives the adjustment block 260 to move leftward, so that the first handling device 300 can subsequently accurately clamp the spring nut.

[0077] It is not difficult to understand that the first limiting groove 251, the second limiting groove 261, the inclined guide groove 262 and the adjustment block 260 can adjust the posture of the spring nut so that the line between the two vertices of the hexagonal nut of the spring nut can be parallel to the left and right directions, thereby enabling the first conveying device 300 to accurately clamp the spring nut, avoiding the phenomenon that the first conveying device 300 cannot clamp the spring nut.

[0078] refer to Figure 5 and Figure 6The first feeding device 200 also includes a second linear cylinder 220, a third linear cylinder 230 and an obstruction rod 221. The cylinder body of the third linear cylinder 230 is arranged on the bracket, the piston rod of the third linear cylinder 230 is connected to the cylinder body of the second linear cylinder 220, and the piston rod of the second linear cylinder 220 is connected to the obstruction rod 221. The second linear cylinder 220 can drive the obstruction rod 221 to descend so that the obstruction rod 221 passes through the threaded hole on the leftmost shrapnel nut in the conveying trough 292. The third linear cylinder 230 can drive the second linear cylinder 220 to move to the right so that the leftmost shrapnel nut in the conveying trough 292 is disengaged from the abutment with the shrapnel nut in the first limiting groove 251.

[0079] It is understood that after the leftmost spring nut in the conveying trough 292 falls into the first limiting groove 251, the spring of the spring nut in the first limiting groove 251 will abut against the spring of the leftmost spring nut in the next conveying trough 292. Because the spring edge of the spring nut is provided with a circle of serrations, the leftmost spring nut in the conveying trough 292 will hinder the rotation of the spring nut in the first limiting groove 251. After the leftmost spring nut in the conveying trough 292 falls into the first limiting groove 251, the second linear cylinder 220 drives the blocking rod 221 downward, so that the blocking rod 221 passes through the threaded hole of the leftmost spring nut in the next conveying trough 292. Then the third linear cylinder 230 drives the second linear cylinder 220 to move to the right, and the second linear cylinder 220 drives the blocking rod 221 to move to the right, so that all the spring nuts in the conveying groove 292 move to the right together, thereby causing the spring nut on the far left in the conveying groove 292 to disengage from the contact with the spring nut in the first limiting groove 251, to ensure that the spring nut in the first limiting groove 251 can rotate smoothly to adjust the posture.

[0080] refer to Figure 5The first feeding device 200 also includes a fourth linear cylinder 240, and the limit block 250 can be slidably connected to the bracket in the front and rear directions. The cylinder body of the fourth linear cylinder 240 is arranged on the bracket, and the piston rod of the fourth linear cylinder 240 is connected to the limit block 250. The fourth linear cylinder 240 can drive the limit block 250 to move backward so that the spring nut in the first limit groove 251, the second limit groove 261 and the inclined guide groove 262 are away from the straight vibration track 291 and the second linear cylinder 220. It can be understood that after the spring nut moves into the second limiting groove 261 and fits against the inner wall of the second limiting groove 261, the fourth linear cylinder 240 drives the limiting block 250 to move backward, so that the first linear cylinder 210 and the adjustment block 260 move backward, and the spring nut in the first limiting groove 251, the second limiting groove 261 and the inclined guide groove 262 is away from the straight vibration rail 291 and the second linear cylinder 220. The spring nut away from the straight vibration rail 291 and the second linear cylinder 220 can stop vibrating, so that the spring nut can be separated from the vibration influence of the straight vibration rail 291, so that the subsequent first conveying device 300 can more accurately clamp the spring nut in the first limiting groove 251.

[0081] refer to Figure 5 and Figure 6 The first feeding device 200 further includes a stopper 270, which is disposed on a bracket. The stopper 270 is disposed behind the straight vibration track 291. The stopper 270 is capable of closing the opening on the right side of the first limiting groove 251. After the fourth linear cylinder 240 drives the stopper 250 to move backward, the stopper 250 is capable of closing the opening on the right side of the first limiting groove 251, thereby preventing the spring nut from being separated from the first limiting groove 251. As an embodiment of the present invention, a ball spring pin is provided on the stopper 270, and the ball of the ball spring pin is capable of abutting against the spring of the spring nut in the first limiting groove 251, so that the spring of the spring nut is pressed against the inner wall of the first limiting groove 251. It can be understood that during the backward movement of the limit block 250, the ball of the ball spring pin is compressed. After the limit block 250 moves into place, the ball extends out and abuts against the spring sheet of the spring sheet nut in the first limit groove 251, so that the spring sheet of the spring sheet nut is pressed against the inner wall of the first limit groove 251, thereby avoiding the shaking of the spring sheet nut and further improving the accuracy of the first handling device 300 in clamping the spring sheet nut.

[0082] The feeding process of the first feeding device 200 is roughly as follows:

[0083] Step 1: The leftmost spring nut in the conveying trough 292 falls into the first limiting groove 251 on the limiting block 250;

[0084] Step 2: The second linear cylinder 220 drives the blocking rod 221 downward, so that the blocking rod 221 passes through the threaded hole of the leftmost spring nut in the next conveying trough 292;

[0085] Step 3: The third linear cylinder 230 drives the second linear cylinder 220 to move rightward, so that the leftmost spring nut in the conveying groove 292 is disengaged from the spring nut in the first limiting groove 251;

[0086] Step 4: The first linear cylinder 210 drives the adjustment block 260 to move rightward, causing the spring nut in the first limiting groove 251 to abut against two opposite side walls of the inclined guide groove 262 and rotate. The spring nut moves into the second limiting groove 261 and abuts against the inner wall of the second limiting groove 261, so that the line connecting the two opposite vertices of the hexagonal nut of the spring nut is parallel to the left and right direction.

[0087] Step 5: The fourth linear cylinder 240 drives the limiting block 250 to move backward, so that the stopper 270 closes the right opening of the first limiting groove 251;

[0088] Step 6: The first transport device 300 clamps the hexagonal nut of the spring nut in the first limiting groove 251 , the second limiting groove 261 , and the inclined guide groove 262 ;

[0089] Step 7: The first linear cylinder 210 drives the adjusting block 260 to move leftward, and the first transport device 300 moves the clamped spring nut away.

[0090] refer to Figure 11 and Figure 12The first transport device 300 includes a first YZ-axis drive assembly 310, a first clamping cylinder 320 and two first clamping jaws 330. The output end of the first YZ-axis drive assembly 310 is connected to the first clamping cylinder 320, and the two output ends of the first clamping cylinder 320 are respectively connected to the two first clamping jaws 330. The first YZ-axis drive assembly 310 is used to drive the first clamping cylinder 320 to move in the left and right directions and the up and down directions. The first clamping cylinder 320 is used to drive the two first clamping jaws 330 to move closer to or away from each other so that the two first clamping jaws 330 can clamp or loosen the spring nut. It is understood that the first YZ-axis drive assembly 310 drives the first clamping cylinder 320 to move left and right and up and down, allowing the first clamping cylinder 320 to move above the discharge end of the first feeding device 200. The first clamping cylinder 320 then drives the two first clamping jaws 330 to approach each other, allowing the two first clamping jaws 330 to clamp the spring nut at the discharge end of the first feeding device 200. The first YZ-axis drive assembly 310 then drives the first clamping cylinder 320 to move left and right and up and down, causing the two first clamping jaws 330 carrying the spring ends of the spring nuts to press against the circuit board, and aligning the threaded holes of the spring nuts with the first mounting holes of the circuit board.

[0091] refer to Figure 12 The two first clamping jaws 330 each have a third limiting groove 331 formed on the opposing side thereof. The two third limiting grooves 331 are used to accommodate the spring nut, and the inner walls of the two third limiting grooves 331 are used to clamp the spring nut. The two first clamping jaws 330 each have a semicircular hole 332 formed on the opposing side thereof. The two semicircular holes 332 are respectively connected to the two third limiting grooves 331 and are used to pass the threaded end of the copper column. It is understood that when the two first clamping jaws 330 are brought close to each other, the two third limiting grooves 331 form a hexagonal groove, allowing the hexagonal body of the spring nut to be positioned within the two third limiting grooves 331. The inner walls of the two third limiting grooves 331 clamp the hexagonal body of the spring nut. The bottom walls of the two first limiting grooves are each provided with a semicircular hole 332. After the inner walls of the two third limiting grooves 331 clamp the spring nut, the two semicircular holes 332 combine to form a complete circular hole. These holes are used to allow the threaded end of the copper pillar to pass through, avoiding the threaded end of the copper pillar, allowing the copper pillar to rotate and rise smoothly. In conjunction with the first feeding device 200, the two first clamping jaws 330 can accurately clamp the spring nut.

[0092] refer to Figure 13The second handling device 500 includes a second Z-axis drive assembly 510, a second flip assembly 520, a second clamping cylinder 530 and two second clamping claws 540. The output end of the second Z-axis drive assembly 510 is connected to the second flip assembly 520, and the output end of the second flip assembly 520 is connected to the second clamping cylinder 530. The two output ends of the second clamping cylinder 530 are respectively connected to the two second clamping claws 540. The second Z-axis drive assembly 510 is used to drive the second flip assembly 520 to rise or fall, and the second clamping cylinder 530 is used to drive the two second clamping claws 540 to move closer to or away from each other, so that the two second clamping claws 540 can clamp the copper column at the discharge end of the second feeding device 400, and enable the two second clamping claws 540 to transport the copper column to the output end of the mobile rotation drive device 600. The second flip assembly 520 is used to drive the second clamping cylinder 530 to flip 180° so that the large ends of the copper columns clamped by the two second clamping claws 540 can face downward.

[0093] It is understood that the second Z-axis drive assembly 510 drives the second flip assembly 520 to rise, and the second clamping cylinder 530 drives the two second clamping jaws 540 to approach each other, so that the two second clamping jaws 540 can clamp the copper column at the discharge end of the second feeding device 400. The second flip assembly 520 then drives the second clamping cylinder 530 to flip 180°, so that the two second clamping jaws 540 and the copper column clamped by the two second clamping jaws 540 can flip 180°, so that the large end of the copper column faces downward and the threaded end of the copper column faces upward. The second Z-axis drive assembly 510 then drives the second flip assembly 520 to descend, and the second clamping cylinder 530 drives the two second clamping jaws 540 to move away from each other, so that the two second clamping jaws 540 can transport the copper column to the output end of the mobile rotation drive device 600.

[0094] It should be explained that the reference Figure 2 In the present invention, the copper post includes a threaded end and a large end. The large end is a hexagonal nut, and the threaded end is a threaded post. Because the spring nut presses against the upper surface of the circuit board, the large end of the copper post faces downward for smooth threaded engagement. After the threaded end of the copper post is threadedly connected to the spring nut, the large end of the copper post presses against the lower surface of the circuit board, and the spring nut presses against the upper surface of the circuit board, thereby securing the copper post to the circuit board.

[0095] refer to Figure 13The mobile rotation drive device 600 includes a second YZ-axis drive component 610, a motor 620 and a positioning column 630. The output end of the second YZ-axis drive component 610 is connected to the motor 620, and the output end of the motor 620 is connected to the positioning column 630. A positioning groove is provided on the upper surface of the positioning column 630, and the positioning groove is used to accommodate the large end of the copper column. The second YZ-axis drive component 610 is used to drive the motor 620 to move in the left and right directions and the up and down directions, so that the threaded end of the copper column in the positioning groove can pass through the first positioning hole on the circuit board and the threaded hole of the spring nut. The motor 620 is used to drive the positioning column 630 to rotate, so that the inner wall of the positioning groove drives the copper column to rotate, and the threaded end of the copper column can be threadedly connected to the inner wall of the threaded hole of the spring nut.

[0096] It is understandable that the positioning groove on the positioning post 630 is used to accommodate the large end of the copper post, and the second transport device 500 transports the copper post to the positioning groove on the positioning post 630. The second YZ-axis drive assembly 610 drives the motor 620 to descend and move to the right, so that the motor 620, the positioning post 630 and the copper post on the positioning post 630 move to the bottom of the circuit board on the two conveyor rails 110, and aligns the threaded end of the copper post with the first mounting hole on the circuit board. Then the second YZ-axis drive assembly 610 drives the motor 620 to rise, so that the threaded end of the copper post on the positioning post 630 can be inserted into the first mounting hole on the circuit board and the threaded hole of the spring nut. At the same time, the motor 620 drives the positioning post 630 to rotate, so that the inner wall of the positioning groove drives the copper post to rotate, and then the threaded end of the copper post is threadedly connected to the threaded hole of the elastic nut to complete the installation of the copper post.

[0097] refer to Figure 14The third handling device 800 includes a third clamping cylinder 810, a third flipping assembly 830, a third XZ-axis driving assembly 860, a fourth clamping cylinder 840, two third clamping claws 820 and two fourth clamping claws 850. The output end of the third flipping assembly 830 is connected to the third clamping cylinder 810, and the two output ends of the third clamping cylinder 810 are respectively connected to the two third clamping claws 820. The third clamping cylinder 810 is used to drive the two third clamping claws 820 to move closer to or away from each other. The third flipping assembly 830 is used to drive the third clamping cylinder 810 to flip 180° so that the two third clamping claws 820 can clamp the third The three feeding devices 700 are used to feed the rubber pellets at the discharge end, and the buckled end of the rubber pellets is facing upward. The output end of the third XZ-axis driving component 860 is connected to the fourth clamping cylinder 840. The two output ends of the fourth clamping cylinder 840 are respectively connected to the two fourth clamping jaws 850. The fourth clamping cylinder 840 is used to drive the two fourth clamping jaws 850 to move closer to or away from each other. The third XZ-axis driving component 860 is used to drive the fourth clamping cylinder 840 to move in the front-to-back direction and the up-and-down direction, so that the two fourth clamping jaws 850 can clamp the rubber pellets clamped by the two third clamping jaws 820, and transport the rubber pellets to the output end of the mobile pushing device 900.

[0098] It is understood that the third flipping assembly 830 drives the third clamping cylinder 810 and the two third clamping jaws 820 to flip 180°, so that the third clamping jaw 820 is close to the discharge end of the third feeding device 700. The third clamping cylinder 810 drives the two third clamping jaws 820 to move closer together, so that the two third clamping jaws 820 clamp the rubber pellets at the discharge end of the third feeding device 700. The third flipping assembly 830 then drives the third clamping cylinder 810 and the two third clamping jaws 820 to flip 180°, so that the interlocking ends of the rubber pellets clamped by the two third clamping jaws 820 face upward. The third XZ-axis drive assembly 860 drives the fourth clamping cylinder 840 to move in the front-to-back and up-to-down directions, so that the two fourth clamping jaws 850 move to the two third clamping jaws 820. The fourth clamping cylinder 840 drives the two fourth clamping jaws 850 to move closer together, so that the two fourth clamping jaws 850 clamp the rubber pellets clamped by the two third clamping jaws 820. The two third clamps 820 release the rubber pellets, and the third XZ-axis drive assembly 860 continues to drive the fourth clamping cylinder 840 to move in the front-to-back direction and the up-down direction, so that the two fourth clamps 850 can transport the rubber pellets to the output end of the mobile pushing device 900.

[0099] refer to Figures 14 to 16The mobile pushing device 900 includes a third Y-axis drive component 910, a lifting cylinder 920 and a pushing rod 930. The output end of the third Y-axis drive component 910 is connected to the lifting cylinder 920, and the piston rod of the lifting cylinder 920 is connected to the lower end of the pushing rod 930. The upper end of the pushing rod 930 is used to pass through the blind hole on the rubber particle. The third Y-axis drive component 910 is used to drive the lifting cylinder 920 to move in the left and right directions, and the lifting cylinder 920 is used to drive the pushing rod 930 to move in the up and down directions, so that the buckling end of the rubber particle on the pushing rod 930 can pass through the second mounting hole on the circuit board and the rubber particle is buckled to the circuit board.

[0100] It is understood that the third transport device 800 transports the plastic pellets onto the push rod 930, so that the upper end of the push rod 930 is inserted into the blind hole in the plastic pellets. The third Y-axis drive assembly 910 then drives the lifting cylinder 920 to move below the circuit boards on the two conveyor rails 110, so that the snap-on end of the plastic pellets on the push rod 930 aligns with the second mounting hole of the circuit board. The lifting cylinder 920 then drives the push rod 930 upward. Under the pushing action of the push rod 930, the snap-on end of the plastic pellets passes through the second mounting hole of the second circuit board, snapping the plastic pellets onto the circuit board.

[0101] refer to Figure 15 and Figure 16 The mobile pushing device 900 also includes a mounting plate 940 and a mounting block 950. The mounting plate 940 is connected to the output end of the third Y-axis drive assembly 910. The cylinder body of the lifting cylinder 920 is connected to the mounting plate 940. The mounting block 950 is connected to the mounting plate 940. A guide hole 952 parallel to the up and down direction is opened on the mounting block 950. The pushing rod 930 is inserted into the guide hole 952. The mounting block 950 can abut against the rubber particles. A positioning enclosure 951 is provided on the mounting block 950. The positioning enclosure 951 is used to abut against the rubber particles. It can be understood that the mounting block 950 can abut against the rubber particles, so that the mounting block 950 can support the rubber particles. The mounting block 950 can drive the rubber particles to rise, making the rubber particles more stable in the upward process. Finally, the pushing rod 930 rises and pushes the buckled end of the rubber particles through the second mounting hole of the circuit board. The positioning enclosure 951 can abut against the rubber particles, and the positioning enclosure 951 supports the rubber particles, making the rubber particles more stable when moving in the left and right directions.
