[0002] In the manufacturing process of PCB boards, various electronic components need to be assembled and welded on the PCB boards, including capacitors, which are installed at corresponding positions on the PCB boards through PCB capacitor welding and assembly equipment. In existing PCB capacitor welding and assembly equipment, the capacitor feeding mechanism usually includes a vibration plate and a direct vibration conveying device, through which the scattered capacitors are conveyed one by one to the direct vibration material path of the direct vibration conveying device, and then the capacitors are conveyed forward to the feeding station along a straight line by the direct vibration conveying device. In actual production, the pins of the capacitors are usually preliminarily bent before feeding, and the existing capacitor feeding mechanism, although it can realize the sorting and feeding of capacitors to the feeding station one by one, cannot guarantee that the bottom of each capacitor transported to the feeding station is uniform in orientation and the bending direction of the pins is uniform. Therefore, it is usually necessary for a manipulator or other device to detect the pins of the capacitors and adjust their positions to make the bottom orientation of the capacitors uniform and the bending direction of the pins uniform, resulting in low feeding efficiency.

[0032] like Figure 7 As shown, at the two ends of the capacitor 700 in the axial direction, one end of the lead pin 710 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 has been preliminarily bent before loading, and the pin 710 usually has one or two bends to Figure 7 Taking the capacitor 700 as an example, the pin 710 of the capacitor 700 has two bends, wherein the pin 710 is led out from the bottom of the capacitor 700 along the axial direction of the capacitor 700, then bent in the radial direction of the capacitor 700, and then bent in the axial direction of the capacitor 700. Figure 7 When the pin 710 of the capacitor 700 is bent at one place, the pin 710 is led out from the bottom of the capacitor 700 along the axial direction of the capacitor 700 and then bent in the radial direction of the capacitor 700.

[0033] Reference Figures 1 to 5According to the first aspect of the present invention, the automatic capacitor feeding mechanism includes a vibration plate 100, a direct vibration conveying device, a hanging plate 250 and a guide structure 260. The vibration plate 100 is used to place the capacitor 700, and the vibration plate 100 is provided with a discharge port 110; the direct vibration conveying device includes a straight vibrator 210 and a first receiving plate 220 and a second receiving plate 230 installed on the straight vibrator 210. The first receiving plate 220 and the second receiving plate 230 are arranged at an angle, and one end of the second receiving plate 230 is connected to one end of the first receiving plate 220 or close to each other, so that the first receiving plate 220 and the second receiving plate 230 surround The straight vibration material channel 240 is formed together, and the straight vibration material channel 240 is connected to the discharge port 110. The first material receiving plate 220 is inclined relative to the horizontal direction. The first material receiving plate 220 is used to support the peripheral side wall of the capacitor 700, and the second material receiving plate 230 is used to support the top of the capacitor 700; the hanging plate 250 is arranged at one end of the first material receiving plate 220 away from the second material receiving plate 230, and the hanging plate 250 is used to suspend the pins 710 of the capacitor 700; the guide structure 260 is arranged on one side of the first material receiving plate 220, and the guide structure 260 is used to make the pins 710 of the capacitor 700 be suspended on the hanging plate 250 according to a uniform bending direction.

[0034] Exemplarily, the length direction of the second material receiving plate 230 is the extension direction of the straight vibrating material channel 240, and the lower end of the second material receiving plate 230 is connected to or close to the lower end of the first material receiving plate 220. After the capacitor 700 is input into the straight vibrating material channel 240, the first material receiving plate 220 is below the capacitor 700 to support the peripheral side wall of the capacitor 700, and the second material receiving plate 230 supports the top of the capacitor 700, that is, 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. Therefore, the straight vibrating material channel 240 transports the capacitor 700 along the radial direction of the capacitor 700.

[0035] During the operation of the automatic capacitor feeding mechanism provided by the present invention, the vibrating plate 100 can input the capacitors 700 stored therein into the straight vibration channel 240 one by one from the discharge port 110, and the straight vibration channel 240 can convey the capacitors 700 along the radial direction of the capacitors 700. When the capacitors 700 have not reached the hanging plate 250, due to the friction resistance between the first receiving plate 220 and the peripheral side wall of the capacitors 700, the capacitors 700 can roll on the first receiving plate 220, wherein the capacitors 700 with their bottoms facing the hanging plate 250 can rotate and hang to the hanging plate 250 when rolling to the hanging plate 250. On the board, and under the action of the guiding structure 260, the pins 710 of the capacitor 700 will be hung on the hanging plate 250 in a uniform bending direction. Therefore, the automatic capacitor feeding mechanism provided by the present invention can transport the capacitor 700 to the straight vibration material channel 240 and use the hanging plate 250 to screen out the capacitors 700 with uniform bottom orientation and uniform bending direction of the pins 710, so that the downstream mechanism can take away the capacitors 700 with the pins 710 hanging on the hanging plate 250 from the straight vibration material channel 240, eliminating the step of the downstream mechanism adjusting the capacitor 700 to make the bottom orientation of the capacitor 700 and the bending direction of the pins 710 uniform, thereby improving the feeding efficiency.

[0036] According to some embodiments of the present invention, the direct vibration conveying device is provided with a separation structure, which is used to separate the capacitor 700 whose bottom is away from the hanging plate 250 from the straight vibration material channel 240, so that the capacitor 700 conveyed to the end of the straight vibration material channel 240 away from the vibration disk 100 are all capacitors 700 with their bottoms facing the hanging plate 250 and their pins 710 suspended on the hanging plate in a uniform bending direction, so that the downstream mechanism can take materials from the end of the straight vibration material channel 240 away from the vibration disk 100 without distinguishing the capacitors 700.

[0037] According to some embodiments of the present invention, the separation structure includes a capacitor blanking port 231, which is disposed on the second receiving plate 230, and the capacitor blanking port 231 is disposed opposite to the hanging plate 250, and a capacitor recovery device 400 is disposed on the side of the capacitor blanking port 231 away from the hanging plate 250. Figure 2In the orientation shown in FIG. 2 , the capacitor blanking opening 231 is located below the hanging plate 250, and the capacitor recovery device 400 is located at the lower side of the capacitor blanking opening 231. Through the above arrangement, when the capacitor 700 is conveyed by the straight vibration channel 240, when the capacitor 700 with the bottom facing away from the hanging plate 250 passes through the capacitor blanking opening 231, since the pins 710 are not suspended on the hanging plate 250, these capacitors 700 with the bottom facing away from the hanging plate 250 will fall from the capacitor blanking opening 231 into the capacitor recovery device 400, so as to separate the capacitor 700 with the bottom facing away from the hanging plate 250 from the straight vibration channel 240, so that the capacitors 700 conveyed to the end of the straight vibration channel 240 away from the vibration disk 100 are all capacitors 700 with the bottom facing the hanging plate 250 and the pins 710 suspended on the hanging plate 250 in a uniform bending direction, so that the downstream mechanism can take the material from the end of the straight vibration channel 240 away from the vibration disk 100.

[0038] Of course, it is conceivable that in other embodiments, the above-mentioned separation structure may also be arranged in other ways. For example, the separation structure includes a separation groove, which is arranged on a side surface of the second receiving plate 230 facing the hanging plate 250, and the separation groove is inclined relative to the length direction of the first receiving plate 220 near the inner wall of the first receiving plate 220. Therefore, during the process of conveying the capacitor 700 by the straight vibration channel 240, the pin 710 of the capacitor 700 with the bottom facing away from the hanging plate 250 will fall into the separation groove, and then the separation groove is close to the inner wall of the first receiving plate 220 and abuts against the pin 710 of the capacitor 700 with the bottom facing away from the hanging plate 250, so as to push the bottom of the capacitor 700 with the bottom facing away from the hanging plate 250 away from the second receiving plate 230, thereby separating the capacitor 700 with the bottom facing away from the hanging plate 250 from the straight vibration channel 240.

[0039] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, a feeding port 241 is provided at one end of the straight vibration material channel 240 away from the material outlet 110, and a material blocking device 300 for opening and closing the feeding port 241 is provided at the feeding port 241. Therefore, when the downstream mechanism does not take the material, the material blocking device 300 closes the feeding port 241, so that the capacitor 700 transported to the feeding port 241 is temporarily stored in the feeding port 241, waiting for the next material taking by the downstream mechanism. 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 can load the material at a fixed point, which is more convenient for the downstream mechanism to take the material.

[0040] It is conceivable that in other embodiments, the downstream mechanism may also determine the position of the capacitor 700 where the pin 710 is suspended on the mounting plate 250 through a visual camera device and then take the material. In this case, the above-mentioned separation structure and material blocking device 300 may not be required.

[0041] According to some embodiments of the present invention, the first material receiving plate 220 and the second material receiving plate 230 are vertically arranged, so that the first material receiving plate 220 can be supported on the peripheral side wall of the capacitor 700, and the second material receiving plate 230 can be attached to the top of the capacitor 700 with the bottom facing the hanging plate 250, thereby, the straight vibration channel 240 can transport the capacitor 700 more smoothly.

[0042] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the first material receiving plate 220 is vertically arranged to the hanging plate 250, and the hanging plate 250 includes a connecting section 250a and a hanging section 250b that are connected to each other, the connecting section 250a is connected to the first material receiving plate 220, and the hanging section 250b protrudes from the first material receiving plate 220 for hanging the pin 710 of the capacitor 700, and the width of the hanging section 250b protruding from the first material receiving plate 220 is smaller than the radius of the capacitor 700, so that when the pin 710 of the capacitor 700 with the bottom facing the hanging plate 250 is hung on the hanging plate 250, the peripheral side wall of the capacitor 700 is also used to contact the first material receiving plate 220, thereby ensuring that the capacitor 700 with the pin 710 hung on the hanging plate 250 can be smoothly transported to the upper material port 241 by the straight vibration channel 240.

[0043] Reference Figure 1 and Figure 2 In some embodiments, the guiding structure 260 includes a guiding piece 261, which is disposed on the side of the hanging plate 250 away from the second receiving plate 230, and a guiding gap is provided between the guiding piece 261 and the hanging plate 250 for the pins 710 of the capacitor 700 to pass through. The length direction of the hanging plate 250 is along the conveying direction of the straight vibration channel 240, and the guiding piece 261 is disposed along the length direction of the hanging plate 250. Therefore, for the capacitor 700 with two bends in the pins 710, the guiding piece 261 can press the second bends of the two pins 710 of the capacitor 700 to the side of the guiding piece 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 achieving the unification of the bending directions of the pins 710 of the capacitor 700.

[0044] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the guide piece 261 is connected to the mounting plate 262, and the mounting plate 262 is mounted on the direct vibration conveying device through a first adjustment structure, and the first adjustment structure is used to adjust the position of the guide piece 261 along the width direction of the hanging plate 250. Therefore, the position of the guide piece 261 can be appropriately adjusted according to the distance between the second bending part of the pin 710 and the center of the capacitor 700.

[0045] In some embodiments, the first adjustment structure may include a locking bolt and a strip hole provided on the mounting plate 262, the locking bolt is passed through the strip hole and is screwed to the direct vibration conveying device, and the length direction of the strip hole is along the width direction of the hanging plate 250. Of course, in other embodiments, the first adjustment structure may also be arranged in other ways, for example, the direct vibration conveying device is provided with a magnetic mounting seat, the mounting plate 262 is slidably mounted on the magnetic mounting seat, the first adjustment structure includes a magnetic seat, the magnetic seat is mounted on the mounting plate 262, the mounting plate 262 can be fixed on the magnetic mounting seat by the magnetic force between the magnetic seat and the magnetic mounting seat, and when the knob of the magnetic seat is turned to make the magnetic force between the magnetic seat and the magnetic mounting seat disappear, the mounting plate 262 can be slid.

[0046] During the specific implementation process, the mounting plate 262 is located on the side of the hanging plate 250 away from the first material receiving plate 220, and the mounting plate 262 is located between the hanging plate 250 and the vibration plate 100. The side of the mounting plate 262 close to the first material receiving plate 220 is inclined relative to the guide plate 261. Therefore, the side of the mounting plate 262 close to the first material receiving plate 220 can guide the second bending part of the two pins 710 of the capacitor 700 to the side of the guide plate 261 close to the first material receiving plate 220.

[0047] It is conceivable that in other embodiments, the above-mentioned guide piece 261 can also be set in other ways. For example, the guide piece 261 is set above the upper end of the hanging plate 250, and the guide piece 261 and the upper end of the hanging plate 250 are surrounded to form a guide groove. Therefore, when the pin 710 of the capacitor 700 is hung on the hanging 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 hanging plate 250, thereby achieving the unification of the bending direction of the pin 710 of the capacitor 700. With this setting, no matter whether the pin 710 of the capacitor 700 has passed through one or two bends, the guide piece 261 can achieve the unification of the bending direction of the pin 710 of the capacitor 700 hung on the hanging plate 250.

[0048] Reference Figure 1 and Figure 2According to some embodiments of the present invention, the guiding structure 260 includes a magnet 263, which is mounted on a side of the hanging plate 250 away from the second receiving plate 230, and the magnet 263 is extended along the length direction of the hanging plate 250. When the pin 710 of the capacitor 700 is hung on the hanging plate 250, the magnet 263 is located on one side of the pin 710 of the capacitor 700 to attract the pin 710 of the guiding capacitor 700. Therefore, when the two pins 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 pins 710 of the capacitor 700, so that the two pins 710 of the capacitor 700 are arranged along the length direction of the hanging plate 250, thereby achieving the unification of the bending direction of the pins 710 of the capacitor 700. In addition, the pins 710 of the capacitor 700 can also be restricted from falling off from the hanging plate 250.

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

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

[0051] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, the blocking device 300 includes a blocking piece 310 rotatably mounted on the loading port 241, a reset structure 320 is provided between the blocking piece 310 and the direct vibration conveying device, the blocking piece 310 can rotate between the blocking position and the avoidance position, and the reset structure 320 is used to drive the blocking piece 310 to rotate from the avoidance position to the blocking position. Therefore, when the PCB capacitor welding assembly equipment takes the capacitor 700 from the loading port 241, the capacitor 700 can push the blocking piece 310 to rotate from the blocking position to the avoidance position so that the capacitor 700 can leave the loading port 241. After the capacitor 700 leaves the loading port 241, the blocking piece 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 blocking device 300 does not require additional control and is convenient to use.

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

[0053] It is conceivable that the above-mentioned material blocking device 300 can also be set up in other ways. For example, the material blocking device 300 can include two symmetrically arranged spring top beads. When the pressure of the capacitor 700 on the spring top beads is large enough, the capacitor 700 can push the spring top beads to contract. Therefore, when the PCB capacitor welding assembly equipment takes the capacitor 700 from the loading port 241, the capacitor 700 can push the spring top beads to contract to open the loading port 241. After the PCB capacitor welding assembly equipment takes away a capacitor 700, the spring top bead automatically pops out, thereby closing the loading port 241.

[0054] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, the vibrating disk 100 has a spiral feeding track 120, the upper end of the spiral feeding track 120 extends to the discharge port 110, the straight vibration channel 240 is arranged along the feeding direction of the upper end of the spiral feeding track 120, the first receiving plate 220 is connected to the spiral feeding track 120 through the guide and diverter 500, and the guide and diverter 500 is used to guide the axial direction of the capacitor 700 from the feeding direction along the upper end of the spiral feeding track 120 to the width direction along the first receiving plate 220. Through the above arrangement, the capacitor 700 output from the discharge port 110 can enter the straight vibration channel 240 in the posture of the axial direction along the width direction of the first receiving plate 220, so as to achieve the goals of the pins 710 of the capacitor 700 being hung on the hanging plate 250 and the pins 710 being guided.

[0055] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, the guide and steering member 500 includes a transition portion 510 and a guide and steering portion 520. The transition portion 510 has a transition groove 511 that is connected to the straight vibration material channel 240. The inner wall of the transition groove 511 and the lower side wall of the discharge port 110 are in an arc transition. The upper and lower projections of the guide and steering portion 520 are in an arc shape. The lower end of the guide and steering portion 520 is connected to the inner wall of the transition groove 511. Thus, the guide and steering portion 520 and the transition portion 510 are enclosed to form an arc-shaped upper and lower projection. The turning channel 521, the spiral feeding track 120 is connected to the turning channel 521. Through the above arrangement, the capacitor 700 output by the spiral feeding track 120 can smoothly pass through the turning channel 521 into the transition groove 511 and then into the straight vibration channel 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 is turned from the feeding direction along the upper end of the spiral feeding track 120 to the width direction along the first receiving plate 220.

[0056] Of course, it is conceivable that in some embodiments, the first receiving plate 220 can be directly extended to the upper end of the spiral feeding track 120, and then the lower end of the above-mentioned guide and steering portion 520 can be connected to the first receiving plate 220. At this time, the above-mentioned transition portion 510 may not be set.

[0057] It is conceivable that in other embodiments, the straight vibration channel 240 is arranged perpendicular to the feeding direction of the upper end of the spiral feeding track 120, and the straight vibration channel 240 is connected to the upper end of the spiral feeding track 120, that is, the first receiving plate 220 and the second receiving plate 230 extend to the upper end of the spiral feeding track 120, and the first receiving plate 220 is on the lower side of the capacitor 700 transported to the upper end of the spiral feeding track 120. At this time, the upper end of the spiral feeding track 120 can push the capacitor 700 into the straight vibration channel 240 in the horizontal direction. Since the first receiving plate 220 is inclined relative to the horizontal direction, during this process, the capacitor 700 rotates and tilts under the action of gravity until it is supported by the first receiving plate 220, thereby the axial rotation of the capacitor 700 is along the width direction of the first receiving plate 220.

[0058] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the capacitor recovery device 400 is provided with a capacitor recovery channel 410, and one end of the capacitor recovery channel 410 close to the vibration disk 100 is connected to the inside of the vibration disk 100, and the capacitor recovery channel 410 is used to return the capacitor 700 located in the capacitor recovery channel 410 to the inside of the vibration disk 100. Through the above configuration, the capacitor 700 dropped from the capacitor drop opening 231 into the capacitor recovery device 400 can be returned to the vibration disk 100 through the capacitor recovery channel 410 and then re-loaded.

[0059] In a specific implementation process, the capacitor recovery channel 410 can be set to be inclined or curved, so that the capacitor recovery channel 410 can send the capacitor 700 located in the capacitor recovery channel 410 back to the inside of the vibration disk 100.

[0060] The PCB capacitor welding assembly equipment according to the second aspect of the embodiment of the present invention includes the above-mentioned capacitor automatic feeding mechanism.

[0061] The PCB capacitor welding assembly equipment provided by the present invention can realize conveying the capacitor 700 to the straight vibration material channel 240 through the above-mentioned capacitor automatic feeding mechanism and use the hanging plate 250 to screen out the capacitors 700 with uniform bottom orientation and uniform bending direction of the pins 710, so that the downstream mechanism can take away the capacitors 700 with the pins 710 suspended on the hanging plate 250 from the straight vibration material channel 240, eliminating the step of the downstream mechanism adjusting the capacitors 700 to make the bending direction of the pins 710 of the capacitors 700 uniform, thereby improving the feeding efficiency.

[0062] Reference Figure 6 In some embodiments, the PCB capacitor welding assembly equipment may include a frame (not shown in the figure), a pin shaping mechanism 610, a material moving mechanism, a welding mechanism (not shown in the figure) and a PCB loading mechanism 630. The pin shaping mechanism 610, the material moving mechanism, the welding mechanism and the PCB loading mechanism 630 are arranged on the frame, and a welding station is arranged on the frame. Therefore, the PCB loading mechanism 630 can transport the PCB board to the welding station, and the material moving mechanism can transfer the capacitor 700 whose pins 710 at the straight vibration channel 240 are suspended on the hanging plate 250 to the pin shaping mechanism 610 and the PCB board on the welding station in turn. The pin shaping mechanism 610 is used to accurately bend and shape the pins 710 of the capacitor 700, and the welding mechanism is used to weld the capacitor 700 on the welding station to the PCB board.

[0063] Reference Figure 6 In some embodiments, in order to improve the shaping efficiency, a transfer positioning device 640 for positioning the capacitor 700 is also provided on the frame, and the material moving mechanism includes a first material moving device 620 and a second material moving device (not shown in the figure), the first material moving device 620 is used to transfer the capacitor 700 from the capacitor automatic feeding mechanism to the transfer positioning device 640, and the second material moving device can transfer the capacitor 700 from the transfer positioning device 640 to the pin shaping mechanism 610 and the welding station in sequence. Thus, while the previous capacitor 700 is being shaped at the pin shaping mechanism 610, the next capacitor 700 can be transported to the transfer positioning device 640 for positioning, and when the positioned capacitor 700 is transferred to the pin shaping mechanism 610, the pin shaping mechanism 610 can clamp the capacitor 700 faster and then shape the pin 710.
