Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of capacitor feeding, and particularly relates to a capacitor automatic feeding mechanism and a PCB capacitor welding assembly device. BACKGROUND

[0002] In the manufacturing process of a PCB, various electronic components, including capacitors, need to be assembled and welded on the PCB, and the capacitors are installed on the corresponding positions of the PCB by a PCB capacitor welding assembly device. In the existing PCB capacitor welding assembly device, the capacitor feeding mechanism usually comprises a vibrating disc and a straight-vibration conveying device. The scattered capacitors are conveyed one by one to the straight-vibration conveying device by the vibrating disc, and then the capacitors are conveyed forward to the feeding station along a straight line by the straight-vibration conveying device. In actual production, the pins of the capacitors are usually preliminarily bent before feeding. Although the existing capacitor feeding mechanism can realize the one-by-one sorting and feeding of the capacitors to the feeding station, it cannot guarantee that the bottoms of the capacitors conveyed to the feeding station are uniformly oriented and the pin bending directions are uniform. Therefore, it is usually necessary to detect and adjust the positions of the pins of the capacitors by a mechanical hand or other devices to make the bottoms of the capacitors uniformly oriented and the pin bending directions uniform, which results in low feeding efficiency.

[0032] As shown in Figure 7 , the capacitor 700 has two ends in the axial direction, one end of which is the bottom end of the capacitor 700 and the other end is the top end of the capacitor 700. In actual production, the pin 710 of the capacitor 700 is preliminarily bent before feeding, and the pin 710 usually has one bend or two bends to Figure 7 The capacitor 700 shown is an example, the pin 710 of the capacitor 700 has two bends, one of which is bent from the bottom of the capacitor 700 along the axial direction of the capacitor 700 and then bent to the radial direction of the capacitor 700 and then bent to the axial direction of the capacitor 700. Referring to Figure 7 , the pin 710 of the capacitor 700 has one bend, which is bent from the bottom of the capacitor 700 along the axial direction of the capacitor 700 and then bent to the radial direction of the capacitor 700.

[0033] Referring to Figures 1 to 5The capacitor automatic feeding mechanism according to the first aspect embodiment of the application comprises a vibrating disc 100, a straight-vibration conveying device, a hanging plate 250 and a guide structure 260. The vibrating disc 100 is used for placing capacitors 700, and is provided with a discharge port 110. The straight-vibration conveying device comprises a straight vibrator 210 and a first material receiving plate 220 and a second material receiving plate 230 mounted on the straight vibrator 210. The first material receiving plate 220 and the second material receiving plate 230 are arranged at an angle. One end of the second material receiving plate 230 is connected to one end of the first material receiving plate 220 or is close to the one end of the first material receiving plate 220, so that the first material receiving plate 220 and the second material receiving plate 230 form a straight-vibration material channel 240. The straight-vibration material channel 240 is in communication with the discharge port 110. The first material receiving plate 220 is arranged to be inclined relative to the horizontal direction. The first material receiving plate 220 is used for supporting the circumferential side wall of the capacitor 700. The second material receiving plate 230 is used for supporting the top end of the capacitor 700. The hanging plate 250 is arranged at the end of the first material receiving plate 220 away from the second material receiving plate 230. The hanging plate 250 is used for suspending the pin 710 of the capacitor 700. The guide structure 260 is arranged at one side of the first material receiving plate 220. The guide structure 260 is used for making the pin 710 of the capacitor 700 be suspended on the hanging plate 250 in a uniform bending direction.

[0034] For example, the length direction of the second material receiving plate 230 is the extension direction of the straight-vibration material channel 240. The lower end of the second material receiving plate 230 is connected to the lower end of the first material receiving plate 220 or is close to the lower end of the first material receiving plate 220. After the capacitor 700 is input into the straight-vibration material channel 240, the first material receiving plate 220 supports the circumferential side wall of the capacitor 700 below the capacitor 700, and the second material receiving plate 230 supports the top end of the capacitor 700. The axial direction of the capacitor 700 is along the width direction of the first material receiving plate 220, and the radial direction of the capacitor 700 is along the length direction of the first material receiving plate 220. Thus, the straight-vibration material channel 240 conveys the capacitor 700 in the radial direction of the capacitor 700.

[0035] The automatic capacitor feeding mechanism provided by the application can feed the capacitors 700 to the straight-vibration material channel 240 from the discharge port 110 one by one in the working process, the straight-vibration material channel 240 can transport the capacitors 700 along the radial direction of the capacitors 700, and the capacitors 700 can roll on the first material receiving plate 220 due to the frictional resistance between the first material receiving plate 220 and the circumferential wall of the capacitors 700 when the capacitors 700 do not reach the hanging plate 250, wherein the pin 710 on the bottom of the capacitor 700 with the bottom facing the hanging plate 250 can be hung on the hanging plate 250 when the capacitor 700 rolls to the hanging plate 250, and the pin 710 of the capacitor 700 will be hung on the hanging plate 250 in a unified bending direction under the action of the guide structure 260, so that the automatic capacitor feeding mechanism provided by the application can transport the capacitors 700 to the straight-vibration material channel 240 and screen out the capacitors 700 with the bottom facing the unified direction and the pin 710 bending direction unified by using the hanging plate 250, so that the downstream mechanism can take away the capacitors 700 with the pin 710 hung on the hanging plate 250 from the straight-vibration material channel 240, and the step of adjusting the capacitors 700 to make the bottom of the capacitors 700 face the unified direction and the pin 710 bending direction unified is omitted, thereby improving the feeding efficiency.

[0036] According to some embodiments of the application, the straight-vibration conveying device is provided with a separation structure for separating the capacitors 700 with the bottom away from the hanging plate 250 from the straight-vibration material channel 240, so that the capacitors 700 transported to the end of the straight-vibration material channel 240 away from the vibration disc 100 are all capacitors 700 with the bottom facing the hanging plate 250 and the pin 710 hanging on the hanging plate in a unified bending direction, so that the downstream mechanism does not need to distinguish the capacitors 700 and can take the material from the end of the straight-vibration material channel 240 away from the vibration disc 100.

[0037] According to some embodiments of the application, the separation structure comprises a capacitor discharge port 231, the capacitor discharge port 231 is arranged on the second material receiving plate 230, the capacitor discharge port 231 is arranged opposite to the hanging plate 250, and a capacitor recycling device 400 is arranged on the side of the capacitor discharge port 231 away from the hanging plate 250. Referring to Figure 2In the orientation shown in FIG. 1, the capacitor drop port 231 is located below the hanging plate 250, and the capacitor recycling device 400 is located below the capacitor drop port 231. Through the above arrangement, during the process of conveying the capacitor 700 by the straight-vibration material channel 240, the capacitor 700 with the bottom part away from the hanging plate 250 will fall into the capacitor recycling device 400 from the capacitor drop port 231, because the pin 710 is not hung on the hanging plate 250, thereby separating the capacitor 700 with the bottom part away from the hanging plate 250 from the straight-vibration material channel 240, so that the capacitors 700 conveyed to the end of the straight-vibration material channel 240 away from the vibration disc 100 are all the capacitors 700 with the bottom part toward the hanging plate 250 and the pin 710 hung on the hanging plate 250 in a uniform bending direction, which facilitates the downstream mechanism to take the material from the end of the straight-vibration material channel 240 away from the vibration disc 100.

[0038] Of course, it can be imagined that in other embodiments, the above separation structure can also be arranged in other ways, for example, the separation structure includes a separation groove arranged on the side of the second material receiving plate 230 facing the hanging plate 250, and the separation groove is arranged obliquely relative to the length direction of the first material receiving plate 220 near the inner wall of the first material receiving plate 220. Thus, during the process of conveying the capacitor 700 by the straight-vibration material channel 240, the pin 710 of the capacitor 700 with the bottom part away from the hanging plate 250 will fall into the separation groove, and then the inner wall of the separation groove near the first material receiving plate 220 abuts against the pin 710 of the capacitor 700 with the bottom part away from the hanging plate 250 to push the bottom part of the capacitor 700 with the bottom part away from the hanging plate 250 away from the second material receiving plate 230, thereby separating the capacitor 700 with the bottom part away from the hanging plate 250 from the straight-vibration material channel 240.

[0039] Referring to Figure 1 and Figure 3 According to some embodiments of the present application, the end of the straight-vibration material channel 240 away from the discharge port 110 is provided with a feeding port 241, and the feeding port 241 is provided with a material blocking device 300 for opening and closing the feeding port 241. Thus, when the downstream mechanism does not take the material, the material blocking device 300 closes the feeding port 241, so that the capacitors 700 conveyed to the feeding port 241 are temporarily stored in the feeding port 241, waiting for the next time of taking the material by the downstream mechanism, and when the downstream mechanism takes the material, the material blocking device 300 opens the feeding port 241. Through the above arrangement, the capacitor automatic feeding mechanism feeds the capacitors 700 at a fixed point, which is more convenient for the downstream mechanism to take the material.

[0040] It can be imagined that in other embodiments, the downstream mechanism can also determine the position of the capacitor 700 with the pin 710 hung on the hanging plate 250 through a visual photographing device and then take the material, in which case the above separation structure and the material blocking device 300 can not be arranged.

[0041] According to some embodiments of the present application, the first receiving plate 220 is arranged perpendicularly to the second receiving plate 230, so that the first receiving plate 220 can be supported on the circumferential wall of the capacitor 700, and the second receiving plate 230 can be attached to the top of the capacitor 700 facing the hanging plate 250, thereby the straight-vibration material channel 240 can stably transport the capacitor 700.

[0042] With reference to Figure 2 and Figure 3 , according to some embodiments of the present application, the first receiving plate 220 is arranged perpendicularly to the hanging plate 250, the hanging plate 250 comprises a connecting section 250a and a hanging section 250b connected to each other, the connecting section 250a is connected to the first receiving plate 220, and the hanging section 250b protrudes from the first receiving plate 220 for the pins 710 of the capacitor 700 to hang on, the width of the hanging section 250b protruding from the first receiving plate 220 is less than the radius of the capacitor 700, so that when the pins 710 of the capacitor 700 hanging on the hanging plate 250 from the bottom, the circumferential wall of the capacitor 700 is also used to contact the first receiving plate 220, thereby ensuring that the capacitor 700 with the pins 710 hanging on the hanging plate 250 can be stably transported by the straight-vibration material channel 240 to the upward material port 241.

[0043] With reference to Figure 1 and Figure 2 , in some embodiments, the guide structure 260 comprises a guide sheet 261 arranged on the side of the hanging plate 250 away from the second receiving plate 230, and the guide sheet 261 has a guide gap with the hanging plate 250 for the pins 710 of the capacitor 700 to pass through. Wherein, the length direction of the hanging plate 250 is along the conveying direction of the straight-vibration material channel 240, and the guide sheet 261 is arranged along the length direction of the hanging plate 250. So for the capacitor 700 with two bending positions of the pins 710, the guide sheet 261 can press the second bending position of the two pins 710 of the capacitor 700 to the side of the guide sheet 261 close to the first receiving plate 220, so that the two pins 710 of the capacitor 700 are arranged along the length direction of the hanging plate 250, thereby realizing the unification of the bending direction of the pins 710 of the capacitor 700.

[0044] With reference to Figure 1 and Figure 2 , according to some embodiments of the present application, the guide sheet 261 is connected to a mounting plate 262, and the mounting plate 262 is mounted on the straight-vibration conveying device through a first adjusting structure, and the first adjusting structure is used to adjust the position of the guide sheet 261 along the width direction of the hanging plate 250. Thus, the position of the guide sheet 261 can be adjusted according to the distance between the second bending position of the pin 710 and the center of the capacitor 700.

[0045] In some embodiments, the first adjusting structure can include a locking bolt and a strip-shaped hole provided on the mounting plate 262, the locking bolt is threaded through the strip-shaped hole and screwed with the linear vibration conveying device, the length direction of the strip-shaped hole is along the width direction of the abutting plate 250. Of course, in other embodiments, the first adjusting structure can also be provided in other ways, for example, the linear vibration conveying device is provided with a magnetic mounting seat, the mounting plate 262 is slidingly mounted on the magnetic mounting seat, the first adjusting structure includes a magnetic force seat, the magnetic force seat is mounted on the mounting plate 262, and the mounting plate 262 can be fixed on the magnetic mounting seat through the magnetic force between the magnetic force seat and the magnetic mounting seat. When the knob of the magnetic force seat is turned to make the magnetic force between the magnetic force seat and the magnetic mounting seat disappear, the mounting plate 262 can be slid.

[0046] In the specific implementation process, the mounting plate 262 is located on the side of the abutting plate 250 away from the first material receiving plate 220, and the mounting plate 262 is located between the abutting plate 250 and the vibration disc 100. The side surface of the mounting plate 262 close to the first material receiving plate 220 is inclinedly arranged relative to the guide piece 261. Therefore, the side surface of the mounting plate 262 close to the first material receiving plate 220 can guide the second bending position of the two pins 710 of the capacitor 700 to the side of the guide piece 261 close to the first material receiving plate 220.

[0047] It can be imagined that in other embodiments, the guide piece 261 described above can also be provided in other ways, for example, the guide piece 261 is arranged above the upper end of the abutting plate 250, and the guide piece 261 and the upper end of the abutting plate 250 enclose a guide groove. In this way, when the pins 710 of the capacitor 700 are hung on the abutting plate 250, the roots of the two pins 710 of the capacitor 700 are located in the guide groove, so that the two pins 710 of the capacitor 700 are arranged along the length direction of the abutting plate 250, thereby realizing the unification of the bending direction of the pins 710 of the capacitor 700. With this arrangement, whether the pins 710 of the capacitor 700 have been bent once or twice, the guide piece 261 can realize the unification of the bending direction of the pins 710 of the capacitor 700 hung on the abutting plate 250.

[0048] Referring to Figure 1 and Figure 2According to some embodiments of the present invention, the guiding structure 260 includes a magnet 263, which is mounted on one side of the mounting plate 250 away from the second receiving plate 230. The magnet 263 extends along the length of the mounting plate 250. When the leads 710 of the capacitor 700 are suspended on the mounting plate 250, the magnet 263 is located on one side of the leads 710 of the capacitor 700 to attract and guide the leads 710 of the capacitor 700. Thus, when the two leads 710 of the capacitor 700 are made of iron, cobalt, nickel, or other materials that can be attracted by the magnet 263, the magnet 263 can hold the two leads 710 of the capacitor 700, so that the two leads 710 of the capacitor 700 are arranged along the length of the mounting plate 250, thereby achieving uniformity in the bending direction of the leads 710 of the capacitor 700. In addition, it can also prevent the leads 710 of the capacitor 700 from falling off the mounting plate 250.

[0049] Reference Figure 2 According to some embodiments of the present invention, the end of the hanging section 250b near the discharge port 110 is provided with a guiding slope 251 or a guiding arc surface, so that the pin 710 of the capacitor 700 with its bottom facing the hanging plate 250 can be more easily rotated and attached to the hanging plate 250.

[0050] In the specific implementation process, the mounting plate 250 is installed on the first receiving plate 220 through the second adjustment structure to adjust the width of the mounting section 250b protruding from the first receiving plate 220. The second adjustment structure can refer to the setting method of the first adjustment structure, and will not be described in detail here.

[0051] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, the material blocking device 300 includes a material blocking plate 310 rotatably mounted on the loading port 241. A reset structure 320 is provided between the material blocking plate 310 and the direct vibration conveyor. The material blocking plate 310 can rotate between a blocking position and a clearance position. The reset structure 320 is used to drive the material blocking plate 310 to rotate from the clearance position to the blocking position. Thus, when the PCB capacitor soldering assembly equipment takes a capacitor 700 from the loading port 241, the capacitor 700 can push the material blocking plate 310 to rotate from the blocking position to the clearance position so that the capacitor 700 can leave the loading port 241. After the capacitor 700 leaves the loading port 241, the material blocking plate 310 automatically rotates to the blocking position under the action of the reset structure 320 to close the loading port 241. In this way, the material blocking device 300 does not require additional control and is convenient to use.

[0052] In specific implementation, the reset structure 320 can be set as a torsion spring, tension spring or magnetic reset structure, etc.

[0053] It can be imagined that the above-mentioned material blocking device 300 can also be arranged in other ways. For example, the material blocking device 300 can include two symmetrically arranged spring beads. When the pressing force of the capacitor 700 on the spring beads is large enough, the capacitor 700 can push the spring beads to retract. Thus, when the PCB capacitor welding assembly device takes the capacitor 700 from the feeding opening 241, the capacitor 700 can push the spring beads to retract to open the feeding opening 241. After the PCB capacitor welding assembly device takes away one capacitor 700, the spring beads automatically pop out, thereby closing the feeding opening 241.

Through the above arrangement, the capacitor 700 output from the discharging opening 110 can enter the straight vibration track 240 in the posture of the axial direction along the width direction of the first material receiving plate 220, so as to achieve the subsequent goals of hanging the pin 710 of the capacitor 700 on the hanging plate 250 and guiding the pin 710.

[0055] With reference to Figure 4 and Figure 5 According to some embodiments of the present application, the material guiding and turning part 500 includes a transition part 510 and a guiding and turning part 520, the transition part 510 has a transition groove 511 connected to the straight vibration track 240, the inner wall of the transition groove 511 is circularly transitioned between the lower side wall of the discharging opening 110, and the upper and lower projections of the guiding and turning part 520 are arc-shaped, the lower end of the guiding and turning part 520 is connected to the inner wall of the transition groove 511, so that the guiding and turning part 520 and the transition part 510 together form a turning channel 521 with arc-shaped upper and lower projections, the spiral feeding track 120 is connected to the turning channel 521, and through the above arrangement, the capacitor 700 output from the spiral feeding track 120 can smoothly pass through the turning channel 521, enter the transition groove 511 and then enter the straight vibration track 240. When the capacitor 700 moves along the turning channel 521, under the guidance of the turning channel 521, the axial direction of the capacitor 700 changes from the feeding direction along the upper end of the spiral feeding track 120 to the width direction of the first material receiving plate 220.

Through the above-mentioned arrangement, the capacitor 700 dropped into the capacitor recovery device 400 from the capacitor discharge port 231 can be returned to the vibration disc 100 through the capacitor recovery channel 410 and then reloaded.

[0059] In the specific implementation process, the capacitor recovery channel 410 can be arranged obliquely or curvedly, so that the capacitor recovery channel 410 sends the capacitor 700 located in the capacitor recovery channel 410 back to the inside of the vibration disc 100.
