Description

Technical Field

[0001] This utility model belongs to the technical field of material distribution devices, specifically, it relates to an improvement in the structure of a material distribution device. Background Technology

[0002] Patent document CN 106081506 B discloses an electronic component dispensing device, which discloses: a base; and a feeding mechanism having a discharge end, the feeding mechanism being used to convey multiple electronic components toward the discharge end, wherein the electronic components include a first electronic component and a second electronic component; the electronic component dispensing device further includes: a dispensing mechanism disposed on the base and including a first support member movable back and forth on the base, the first support member being used to carry the first electronic component; a second support member movable back and forth on the base, the second support member being used to carry the second electronic component; a connecting rod, one end of the connecting rod being connected to the first support member, the other end of the connecting rod having a flange portion; and an elastic element, the elastic element being... An elastic element is sleeved on the connecting rod, with its two ends abutting against the second support member and the flange, respectively. A stop member is disposed on the base, and a driving unit is used to drive the first support member and the second support member to move back and forth between a material picking position and a material dispensing position. When moving to the material picking position, the first support member and the second support member move closer to each other, while when moving to the material dispensing position, the first support member and the second support member move further apart. The second support member pushes the connecting rod by compressing the elastic element to drive the first support member to move. When the first support member stops moving due to being stopped by the stop member, the driving unit drives the second support member to continue moving.

[0003] This material distribution device uses two cooperating first and second support members to distribute materials. The entire material distribution device has a complex structure. Furthermore, the material distribution device only separates electronic components without a positioning structure after separation. If the locking mechanism with clamping power moves to the first and second support members, it will cause the electronic components to shift, resulting in poor positioning accuracy.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0059] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0060] In some embodiments of this application, a material dispensing device is proposed, including: a support base 100, a material dispensing component, and a material dispensing drive mechanism 400 for driving the material dispensing component to move along the support base 100.

[0061] The support base 100 is used to form the foundation of the entire material distribution device, so as to support and fix the material distribution device. A receiving position 130 and a feeding position 140 are provided on its side.

[0062] The receiving position 130 and the discharge port position of the feeding device used for conveying the bridge rectifier are respectively set.

[0063] When the material distribution component is moved to the receiving position 130 by the material distribution drive mechanism 400, it can receive the conveyed bridge stack from the discharge port of the feeding device.

[0064] The feeding position 140 is used to supply bridge stacks to the adsorption mechanism that picks up the material. When the bridge stacks are transferred to the feeding position 140 by the dispensing component, the locking adsorption mechanism can move to the feeding position 140 to pick up the bridge stacks.

[0065] By setting up a material distribution device, the bridge stack output by the feeding device can be received inside it, and the material distribution drive mechanism 400 drives the material distribution component to the feeding position 140 to distribute the material to the locking and adsorption mechanism.

[0066] In some embodiments of this application, the material dispensing component includes:

[0067] The material distribution substrate 210 includes:

[0068] The main body 211 extends vertically and is a main body plate, which is arranged vertically.

[0069] An extension portion 212 is formed on the main body portion 211 and extends horizontally, and a receiving portion 213 is formed within the extension portion 212.

[0070] The extension 212 is an extension plate provided vertically to the base body 211, and it can be integrally formed with the base body 211.

[0071] The receiving portion 213 is a receiving cavity formed in the extension portion 212 and is provided to extend through the extension portion 212 from top to bottom.

[0072] The material distribution component 220 is slidably connected to the material distribution base 210, and multiple material receiving positions 221 are provided on the material distribution component 220. Specifically, the material distribution component 220 is slidably sliding along the material distribution base 210 so that it can rise or fall relative to the material distribution base 210, so that the material receiving positions inside it can receive the material conveyed by the feeding device and the locking and adsorption mechanism can grab the material.

[0073] In some embodiments of this application, a first sliding assembly is provided between the substrate body 211 and the material distribution component 220. The first sliding assembly includes a first sliding groove provided on the material distribution component 220 and a first sliding rail provided on the substrate body 211.

[0074] Multiple material receiving positions 221 are provided, which can accommodate multiple materials at once, thereby improving the material distribution efficiency.

[0075] In some embodiments of this application, the material holding position includes a first material holding position and a second material holding position, that is, the material dispensing component 220 is provided with two material holding positions.

[0076] The first material receiving position is a first receiving groove formed by an inward recess on the material distribution component 220;

[0077] The second material receiving position includes a second receiving groove formed recessed from the material distribution component 220 and a second clearance groove arranged on one side of the second receiving groove to avoid the pipe feet of the bridge rectifier. The second clearance groove is disposed between the first receiving groove and the second receiving groove.

[0078] The second receiving slot can be used to receive the main body of the bridge rectifier, while the second clearance slot can be used to avoid the bent pipe sections of the bridge rectifier.

[0079] The first receiving slot is used to accommodate the main body of the bridge rectifier, while its feet can extend to the outer area.

[0080] In some embodiments of this application, the material dispensing component includes a positioning unit for positioning the material dispensing component 220 located at the first receiving position 130.

[0081] In some embodiments of this application, the positioning unit includes two positioning blocks 510, which are fixed on both sides of the distributing base 210, extending from the distributing base 210 to the position below the distributing component 220, so as to support and position the distributing component 220 that is slidably connected to the support base 100.

[0082] In some embodiments of this application, the material distribution component includes a material distribution positioning unit 300, which is liftable. When it rises to a preset position, at least part of the positioning material extends out of the material position 221 and simultaneously abuts against the material distribution component 220, driving it to move to the feeding position 140.

[0083] The material distribution and positioning unit 300 is vertically connected to the material distribution base 210 and can move up and down relative to the material distribution base 210. During its upward movement, it will continuously extend a part from the material receiving position 221 to position the material entering the material receiving position 221.

[0084] When the material distribution and positioning unit 300 rises to the preset position, it will abut against the bottom of the material distribution component 220. At this time, it will drive the material distribution component 220 to rise together, so as to drive the material distribution component 220 to the feeding position 140.

[0085] When the material distribution component 220 is docking with the feeding device to receive materials, the material distribution component 220 is positioned by the positioning unit at a position slightly lower than the outlet of the feeding device to receive materials. At this time, the material distribution positioning unit 300 does not operate.

[0086] After receiving the material, when feeding is required, the material distribution and positioning unit 300 can be moved upward. After moving, the material distribution and positioning unit 300 extends from the material position 221 into the insertion hole of the bridge rectifier above it to position the bridge rectifier. At the same time, it drives the material distribution component 220 to move upward and lifts the material distribution component 220 to the feeding position 140 to feed the material.

[0087] The material distribution drive mechanism 400 is connected to the material distribution base 210 for driving the material distribution component to move. It has a first working mode and a second working mode. The first working mode corresponds to the receiving mode, and the second working mode corresponds to the feeding mode.

[0088] When the material distribution drive mechanism 400 is in the first working mode, it drives the material distribution component to move so that multiple material holding positions 221 move to the receiving position 130 to receive materials. By driving the material distribution component to move through the material distribution drive mechanism 400, multiple material holding positions 221 on the material distribution component 220 can receive materials, and multiple materials can be received at one time.

[0089] When the material distribution drive mechanism 400 is in the second working mode, it drives the material distribution component to move between the receiving position 130 and the feeding position 140.

[0090] After all the material receiving positions 221 have received the material, the material distribution drive mechanism 400 can drive the material distribution component to move from the receiving position 130 to the feeding position 140, so that the subsequent locking and adsorption mechanism can pick up the material, thus realizing the transfer of multiple materials at one time.

[0091] After the material at the feeding position 140 is picked up, the material distribution drive mechanism 400 can be activated again to move the material distribution component from the feeding position 140 to the receiving position 130 to continue receiving the material.

[0092] In this embodiment, the material distribution device is configured to cooperate with the material distribution positioning unit 300 by setting a material distribution component 220 that is slidably connected to the material distribution base 210. The lifting and moving of the material distribution component 220 ensures perfect docking and cooperation with the locking and adsorption mechanism. At the same time, the material distribution positioning unit 300 can also extend into the material holding position to position the bridge stack when the material is conveyed to the feeding position 140, ensuring the positional accuracy of the bridge stack when the locking and adsorption mechanism picks up the bridge stack.

[0093] In addition, the material distribution component 220 is equipped with multiple material receiving positions 221. Through the cooperation of the material distribution drive mechanism 400 and the material distribution assembly, the multiple material receiving positions 221 on the material distribution component 220 are moved to pick up materials in sequence, realizing the one-time picking up of multiple materials. At the same time, after picking up the materials, the material distribution drive mechanism 400 drives the material distribution assembly to move from the receiving position 130 to the feeding position 140, and transports the multiple materials obtained at one time to the feeding position 140 at one time. This realizes the reception and transfer of multiple materials at one time, greatly improving the material distribution and transportation efficiency.

[0094] In some embodiments of this application, the material distribution base 210 includes an assembly part 214, which is an assembly plate connected to the bottom of the base body 211.

[0095] In some embodiments of this application, the dispensing device includes:

[0096] A pre-blocking member 600 is connected to the side of the material distribution member 220 near the receiving position 130, and is used to press the part of the bridge extending from the discharge port of the discharge device into the discharge device. A first guide portion 610 is formed on the side of the pre-blocking member 600 near the discharge device.

[0097] The pre-separator includes a connecting part, which is connected to one side of the material distribution component 220;

[0098] The partition is provided perpendicular to the connecting part and has a partition surface facing the discharge port of the feeding device.

[0099] The first guide portion 610 is a first guide surface formed at the end of the partition portion.

[0100] When the feeding device is conveying materials, it drives the materials to move forward along its internal track through vibration. Due to the vibration, the material at the discharge port will protrude 1-2mm from the discharge port. If the material distribution component 220 moves directly to the discharge port, it will damage the material. The pre-separation component 600 can press the protruding part of the material into the feeding device.

[0101] When multiple material receiving positions 221 on the material distribution component 220 receive materials sequentially along the direction that moves away from the feeding position 140, the pre-blocking member 600 first moves to the discharge port. Through the guiding action of the first guide part 610 of the blocking part, it smoothly contacts the material and presses the material into the feeding device.

[0102] In some embodiments of this application, the material distribution component 220 includes:

[0103] Multiple material distribution main bodies 226 are arranged alternately with multiple material receiving positions, that is, the material distribution main body 226 is provided on both sides of each material receiving position 221.

[0104] The material distribution main body 226 is used to press a portion of the bridge stack extending from the discharge port of the discharge device into the discharge device, and a second guide portion 2261 is formed on the side of the material distribution main body 226 near the discharge device.

[0105] When the material distribution component 220 has multiple material holding positions 221, after the first material holding position 221 finishes receiving the material, the material at the outlet of the feeding device will also extend out. At this time, the material at the outlet can be pressed into the feeding device by the material distribution main body 226 between the two material holding positions 221.

[0106] To achieve smooth contact with the material, a second guide section 2261 is also provided on each material distribution body 226.

[0107] The second guide section 2261 is the second guide surface.

[0108] By using the material distribution main body 226 arranged alternately with the multiple material holding positions 221 and the second guide part 2261 provided on the multiple material distribution main body 226, it is ensured that the feeding device can continuously feed materials to the multiple material holding positions.

[0109] In some embodiments of this application, the support base 100 includes a first support base and a second support base. The first support base and the second support base are L-shaped fixing seats.

[0110] The material distribution support 150 is connected to the first support base and the second support base and extends along the moving direction of the material distribution assembly.

[0111] One end of the material distribution support 150 is arranged above the first support base 110 and is locked and fixed to the first support base 110 by screws.

[0112] A support connection portion is formed on one side of the material distribution support 150, and the second support base 120 and the support connection portion are locked and fixed by screws.

[0113] The material distribution stop 520 is used to stop and limit the bridge tack. It is set on the material distribution support 150 and is arranged along the moving direction of the material distribution assembly. A notch is formed between it and the material distribution support 150. The material receiving position 130 is located at the position corresponding to the notch.

[0114] The material separating stop 520 is a material separating stop bar, which is vertically fixed on the material separating support 150. Its length is less than that of the material separating support 150 so that a notch is formed between it and the material separating support 150. The notch is formed at the material receiving position 130.

[0115] The gap is mainly to ensure that the material conveyed by the feeding device can be moved to the material receiving position 221 of the material distribution component 220, so as to avoid the material sent out by the feeding device.

[0116] In some embodiments of this application, the dispensing component includes:

[0117] The sensing unit 530 is assembled onto the material distribution base 210 and is used to sense whether there is a bridge stack in the multiple material storage positions 221.

[0118] The sensing unit 530 includes a sensing assembly plate and a plurality of contact switches 531 mounted in the sensing assembly plate. The plurality of contact switches 531 correspond to a plurality of material holding positions to sense whether there is material in the plurality of material holding positions.

[0119] The sensing assembly plate includes an upper sensing mounting plate and a lower sensing mounting plate, which are mated together to form multiple mounting slots, and multiple contact switches 531 are installed in the multiple mounting slots.

[0120] In some embodiments of this application, the material receiving position 221 is formed with:

[0121] Input bridge rectifier first feed port 223;

[0122] A second feed port 224 is disposed opposite to the first feed port 223.

[0123] The first feed inlet 223 is the first feed inlet, and the second feed inlet 224 is the second feed inlet.

[0124] When the material dispensing assembly moves from the receiving position 130 to the feeding position 140, the first material inlet 223 and the second material inlet 224 are respectively limited by the material dispensing stop 520 and the sensing unit 530.

[0125] During the process of the material distribution component moving from the receiving position 130 to the feeding position 140, the first material inlet 223 can move in contact with the material distribution stop 520, and the second material inlet 224 is limited by the sensing unit 530 to ensure that the material in the receiving position 221 will not fall out or move during the movement of the material distribution component, thus achieving accurate feeding.

[0126] When the material distribution component moves to the feeding position 140, the material distribution positioning unit 300 rises, causing the material distribution component 220 to move upward and protrude from the sensing unit 530 and the material distribution blocking component 520.

[0127] When the material is moved to the feeding position 140, the locking and adsorption mechanism will move to the feeding position 140 to pick up the material. The material distribution and positioning unit 300 will drive the material distribution component 220 to protrude the sensing unit 530 and the material distribution stop 520. At this time, the first material port 223 and the second material port 224 at the material receiving position 221 of the material distribution component 220 are not limited, so the locking and adsorption mechanism can easily perform the material clamping operation.

[0128] In some embodiments of this application, the material dispensing and positioning unit 300 includes:

[0129] The positioning base 310 is slidably connected to the material distribution base 210.

[0130] To achieve a sliding connection between the positioning base 310 and the material distribution base 210, a second sliding component is provided between the positioning base 310 and the material distribution base 210. The second sliding component includes a second sliding groove provided on the positioning base 310 and a second sliding rail provided on the material distribution base 210.

[0131] The material distribution and positioning unit 300 includes multiple positioning pins 320, which are fixed on the positioning base 310.

[0132] The material dispensing lifting component 330 is connected to the positioning base 310 and is used to drive the positioning base 310 to move the positioning pin 320 up and down.

[0133] The material dispensing and lifting component 330 is a material dispensing and lifting cylinder, which is connected to the positioning base 310 and drives the positioning base 310 to move up and down. The positioning pin 320 is fixed on the positioning base 310 and is also driven to move up and down.

[0134] To achieve adaptive positioning of the bridge rectifier, the shape of the positioning pin 320 is set to match the shape of the positioning hole on the bridge rectifier.

[0135] In some embodiments of this application, the material receiving position 221 is formed on the material dispensing main body 226, and a blocking protrusion is provided below the material dispensing main body 226 for abutting and cooperating with the positioning base 310.

[0136] When the positioning base 310 moves upward to the preset position, it abuts against the blocking protrusion and drives the material dispensing body 226 to move upward.

[0138] A second fixing part 225 is provided on the material distribution component 220;

[0139] An elastic connector, with one end connected to the first fixing part 311 and the other end connected to the second fixing part 225, is used to reset the material distribution component 220.

[0140] After the material distribution component 220 completes the feeding by being lifted up by the material distribution positioning unit 300, the material distribution positioning unit 300 will move downward to prevent the material distribution component 220 from getting stuck and unable to return to its initial position. An elastic connector is connected between the positioning base 310 and the material distribution component 220, and the material distribution component 220 is pulled back to its initial position by the elastic connector.

[0141] Furthermore, by connecting an elastic connector between the material distribution component 220 and the positioning base 310, the elastic force of the elastic connector can be used to adapt to the constantly changing distance between the material distribution component 220 and the positioning base 310.

[0142] The first fixing part 311 is a first locking bolt or a first positioning pin fixed to the positioning base 310;

[0143] The second fixing part 225 is a second locking bolt or a second positioning pin fixed to the material distribution part 220.

[0147] The positioning arm 313 is provided with the positioning pin 320. The material distribution component 220 is provided with the positioning channel 222, which is connected to the material receiving position.

[0148] The positioning base 310 is arranged below the material distribution component 220, and a moving space is formed between the positioning base 310 and the material distribution component 220.

[0151] 720 feed screw;

[0152] The material distribution nut assembly 730 is threadedly engaged with the material distribution screw, slidably connected to the material distribution support 150, and fixedly connected to the material distribution base 210.

[0153] The material distribution power component 710 is a material distribution motor, which is connected to the material distribution screw via a coupling.

[0154] To support the feed screw, a first screw support seat and a second screw support seat are provided, both of which are assembled onto the support base 100. The feed screw passes through the first screw support seat and the second screw support seat and is rotatably connected to the first screw support seat and the second screw support seat.

[0155] A third sliding component is provided between the material distribution support 150 and the material distribution nut assembly 730.

[0156] The third sliding assembly includes a third slider 734 and a third slide rail. The third slide rail is disposed on the material distribution support 150, and the third slider 734 is slidably connected to the third slide rail and connected to the material distribution nut assembly 730.

[0157] The third sliding component allows the material distribution nut assembly 730 to slide along the material distribution support 150.

[0158] In some embodiments of this application, the material distribution nut assembly 730 includes:

[0159] The material distribution nut 731 is threadedly connected to the material distribution screw.

[0160] The material distribution nut seat 732 is sleeved on the material distribution nut 731 and fixedly connected to the material distribution nut seat 732;

[0161] The connecting component 733 is connected to the third slider 734, the material distribution nut seat 732 and the material distribution base 210.

[0162] The connecting member 733 is arranged between the third slider 734 and the material distribution nut seat 732, and has a first threaded connection hole and a second threaded connection hole on its upper part, which are used to lock and fix with the third slider 734 and the material distribution nut seat 732 respectively.

[0163] The connecting member 733 extends to the extension 212 of the material distribution base 210, and a snap-fit ​​is formed on its upper part. The connecting member 733 is snapped onto the extension 212 through the snap-fit ​​and is fixedly connected to the material distribution base 210 by screws.

[0164] The material distribution nut seat 732, the material distribution base 210 and the third slider 734 are connected by the connecting component 733. When the material distribution nut seat 732 moves linearly, power is transmitted to the connecting component 733. The connecting component 733 is connected to the material distribution base 210. The connecting component 733 will drive the material distribution base 210 to move linearly along the third slide rail through the third slider 734, thereby realizing the linear movement of the material distribution component.

[0165] The material distribution drive mechanism 400 adopts a material distribution screw and material distribution nut assembly 730 to achieve high-precision position movement control and ensure the accuracy of position switching between each material receiving position 221.

[0166] In some embodiments of this application, a locking forming machine is proposed, including the material dispensing device described in the above embodiments.

[0167] How to use the material distribution device:

[0168] The material distribution drive mechanism 400 operates, controlling the material distribution component to move towards the receiving position 130, until it moves to the first receiving position 221 closest to the receiving position 130 and corresponds to the discharge port position of the feeding device, and the material distribution component 220 is positioned slightly lower than the first receiving position 130 of the feeding device and the sensing unit 530 to receive the material.

[0169] In the initial position, the material distribution component 220 is positioned by the positioning unit. At this time, it is located below the position of the sensing unit 530 and the feeding device to facilitate material receiving. At the initial receiving position 130, the material distribution positioning unit 300 and the material distribution component 220 do not move. When the bridge trolley enters the material receiving position, its two sides are limited by the side wall of the material receiving position, and its rear side is limited by the sensing unit 530.

[0170] After the first material receiving position 221 completes receiving, the material distribution drive mechanism 400 drives the material distribution component to move a preset distance away from the feeding position 140 to the next material receiving position 221 and the corresponding material outlet of the feeding device to receive material. This process is repeated until all material receiving positions 221 have completed receiving.

[0171] After the first material receiving position 221 finishes receiving material, the material distribution drive mechanism 400 continues to drive the material distribution component to move until it moves to the next material receiving position 221 and continues to receive material. By driving the material distribution component to move a small distance through the material distribution drive mechanism 400, all material receiving positions 221 can be completed.

[0172] After receiving the material, the material distribution drive mechanism 400 moves the material distribution component along the direction close to the feeding position 140 to the feeding position 140.

[0173] During the process of moving towards the feeding position 140 after receiving the material, the first material inlet 223 is blocked by the material distribution stop 520, and the second material inlet 224 is limited by the sensing unit 530, so that the material will not fall during the movement.

[0174] The material distribution and positioning unit 300 rises, driving the material distribution component 220 to rise to the second feeding position 140, which is higher than the material distribution stop 520 and the sensing unit 530, for feeding.

[0175] After moving to the feeding position 140, the material distribution component 220 needs to be raised to release the limiting effect of the material distribution blocking component 520 and the sensing unit 530 on the bridge stack, so as to facilitate subsequent gripping. However, after the limiting effect is removed, the position of the bridge stack will change during gripping, resulting in a gripping position deviation.

[0176] Therefore, when moving to the feeding position 140, the material distribution and positioning unit 300 needs to rise to insert the positioning pin 320 into the bridge stack. This achieves the lifting of the material distribution component 220 while simultaneously positioning the bridge stack through the positioning pin 320, ensuring the positional accuracy during gripping.

[0177] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
