[0057] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] Example:

[0059] like Figure 1 to Figure 5 As shown, an embodiment of the present application discloses an automatic screw arrangement and supply device, which can realize multi-channel screw supply continuously and stably, and its specific structure includes: a machine table 1, a storage box 2, a straight vibrator 3, a plurality of feed plates 4, a plurality of screening plates 5, a first driving member 6 and a one-by-one supply mechanism 7.

[0060] The machine 1 is a box-like structure with an internal cavity for accommodating and installing components; and telescopically adjustable height pads are installed at the four corners of the bottom to keep the top surface level.

[0061] The material storage box 2 is installed on the top of the machine platform 1 and has a material storage bin 21 with an upper opening; the material storage box 2 is composed of a square enclosure and a bottom plate installed in the square enclosure, which is convenient for production and assembly.

[0062] The straight vibrator 3 is installed on the top of the machine platform 1 ; the straight vibrator 3 is a device for generating high-frequency linear vibration so that the screws can be uniformly transported to the supply mechanisms 7 one by one along the screening channel 51 .

[0063] A plurality of conveying plates 4 are arranged horizontally side by side and spaced apart, and are vertically installed on the top of the straight vibrator 3, with one end inserted into the storage bin 21. The top surface of each conveying plate 4 is provided with a conveying channel 41 with two ends open; the conveying plate 4 is provided with a plurality of hollow grooves to reduce the overall weight.

[0064] A plurality of screening plates 5 are vertically arranged in the storage bin 21, and correspond one to one with the feed plate 4 and are fitted with each other at the end. The bottom end of the screening plate 5 passes through the storage box 2 and extends into the machine 1. A screening channel 51 is provided on the top surface of the screening plate 5. Both ends of the screening channel 51 are open and inclined. One end of the screening channel 51 close to the feed plate 4 is lower than the other end.

[0065] The first driving member 6 is installed in the machine 1 and is in driving connection with the plurality of screening plates 5 for driving the screening plates 5 to reciprocate vertically; wherein, when the screening plates 5 are at the highest position, the screening channels 51 are connected to the feeding channels 41 .

[0066] The one-by-one supply mechanism 7 is disposed at the other end of the plurality of feeding plates 4 and is used for feeding the screws in the feeding channel 41 one by one.

[0067] In this embodiment, two channels are set, so the feed plate 4 and the screening plate 5 are correspondingly set in two pieces; but it is not limited to this, and it can also be three channels, four channels or more. In actual production, corresponding settings are made according to production needs, so no specific limitation is made.

[0068] It should be noted that, since the travel path of the screw is a straight line, the depth of the screening channel 51 and the feeding channel 41 can be deepened, thereby achieving a large allowable space for the screw length from 4MM to 30MM.

[0069] The main operation process of the above technical solution is:

[0070] When the device is working, a batch of screws are placed in the storage bin 21 on the top of the storage box 2; and the first driving member 6 is started to drive multiple screening plates 5 to move up and down synchronously, so as to continuously sink into or extend out of the screw pile. During the rising process of the screening plate 5, the studs of some screws just fall into the screening channel 51, so after the screening plate 5 extends out of the screw pile, the screws of this part will not fall back into the bolt pile, but will slide along the screening channel 51 to the side close to the feed plate 4 until they are blocked by the end face of the feed plate 4. Afterwards, when the screening plate 5 rises to the highest position, the screening channel 51 docks with the feed channel 41, so the screws will slide onto the feed channel 41; then, under the action of the high-frequency linear vibration generated by the straight vibrator 3, the screws approach the supply mechanism 7 one by one along the feed channel 41; finally, the screws are output to the use device one by one by the supply mechanism 7.

[0071] The utility model forms a multi-channel by arranging a plurality of one-to-one corresponding feed plates 4 and screening plates 5, so that multiple screws can be supplied simultaneously, and a straight channel is designed from feeding to separation. It has the advantages of simple structure, fast feeding speed, good continuous stability, small space occupation, etc., and meets the use requirements of industrial automation production.

[0072] In some embodiments, Figures 4 to 8 As shown, the supply mechanism 7 comprises: a support frame 71, an L-shaped plate 72, a plurality of pipe joints 73, a side plate 74, a movable block 75, a plurality of slide plates 76, a plurality of guide blocks 77, two end plates 78, a top plate 79 and a second driving member 7A.

[0073] The support frame 71 is installed on the top of the machine 1; the support frame 71 is composed of two L-shaped parts, which form a U-shaped structure, and the two are connected by linear grooves and bolts, so as to conveniently adjust the height of the L-shaped plate 72 and facilitate assembly and debugging.

[0074] The L-shaped plate 72 is installed on the support frame 71; the two sides of the bottom of the L-shaped plate 72 are connected to the support claw bolts on the support frame 71, which ensures the installation stability and will not interfere with the arrangement of the pipe joint 73; and a plurality of plug-in through holes corresponding to the pipe joint 73 are opened at the bottom to realize the plug-in connection between the two.

[0075] A plurality of pipe joints 73 are inserted into the bottom surface of the L-shaped plate 72; the lower end of the pipe joint 73 is used to install a flexible hose, so that the screws can be transported to the use equipment through the flexible hose.

[0076] The side plate 74 is installed on the L-shaped plate 72 and forms a concave structure therewith. The side plate 74 is located at the other end of the multiple feed plates 4, and a plurality of transfer grooves 741 are opened on the top surface. The transfer grooves 741 correspond to and are connected with the feed trough 41 one by one. The top surface of the side plate 74 is kept flush with the end of the feed plate 4, so that when the screw enters the transfer groove 741 from the feed trough 41, it can smoothly transition, which improves the conveying stability.

[0077] The movable block 75 is slidably fitted between the side plate 74 and the L-shaped plate 72. A plurality of discharge grooves 751 are provided on the side of the movable block 75 close to the side plate 74. A plurality of limiting slide grooves 752 are provided on the top surface of the movable block 75. The discharge grooves 751 and the limiting slide grooves 752 correspond to each other and are connected.

[0078] A plurality of slide plates 76 are slidably installed in the limiting slide groove 752 one by one, and a slot 761 is provided at one end of the slide plate 76 close to the side plate 74; the width of the slot 761 matches the stud of the screw, thereby ensuring the limiting effect.

[0079] A plurality of guide blocks 77 are mounted one by one on the top surface of the slide plate 76; the guide blocks 77 are cylindrical and rotatably mounted on the slide plate 76, which reduces the resistance encountered when sliding in the guide groove 791 and improves the smoothness of movement.

[0080] Two end plates 78 are mounted on both ends of the side plate 74 respectively.

[0081] The top plate 79 is horizontally arranged between the two end plates 78 and is located above the movable block 75, and a plurality of guide grooves 791 are provided at the bottom. The guide grooves 791 correspond to the guide blocks 77 one by one and slide together. The guide grooves 791 are in a bent linear structure, which improves the conveying stability.

[0082] The second driving member 7A is installed on an end plate 78 and is connected to the movable block 75 for driving the movable block 75 to move back and forth laterally, and at the beginning of the stroke, the limiting slide groove 752 corresponds to and is connected with the pipe joint 73 one by one, and at the end of the stroke, the discharge groove 751 corresponds to and is connected with the pipe joint 73 one by one; the second driving member 7A is a cylinder, and its output shaft passes through the end plate 78 and is threadedly connected with the T-block. A T-slot is provided at one end of the movable block 75, and the T-slot is engaged with the T-block, which ensures stable transmission and is easy to disassemble and maintain, thereby improving the use effect.

[0083] When the movable block 75 is at the beginning of its stroke, the screw moves from the transfer slot 741 to the slot 761, and the lower end extends into the discharge slot 751; thereafter, the second driving member 7A drives the movable block 75 to move toward the end of its stroke, so that the guide block 77 slides along the guide slide slot 791 at the same time, thereby driving the slide plate 76 to slide in the limiting slide slot 752, so that the slot 761 gradually stops engaging the screw; when the movable block 75 is at the end of its stroke, the screw falls from the slot 761 and falls into the discharge slot 751, and then falls into the corresponding pipe joint 73 through the insertion through hole, and is finally transported to the use equipment through the flexible hose.

[0084] Through the above arrangement, a reciprocating motion of the movable block 75 can be used to feed multiple screw channels one by one at the same time, with high speed and high efficiency, and has the advantages of compact structure, stable operation, and convenient disassembly and assembly, and has good practical application effect.

[0085] In some embodiments, Figure 1 and Figure 3 to Figure 8 As shown, it also includes: a plurality of support plates 8, a plurality of support blocks 9, a plurality of strips 10 and a plurality of stop blocks 11.

[0086] Multiple support plates 8 are alternately arranged one by one between multiple feed plates 4 and installed on the top of the straight vibrator 3. Both sides of the support plates 8 are fitted with adjacent feed plates 4. The support plates 8 can limit and clamp the feed plates 4 to improve vertical stability and increase structural strength.

[0087] A plurality of support blocks 9 are mounted one by one on the top surface of the support plate 8 ; the support blocks 9 are T-shaped, and both sides are connected to the strip plates 10 by bolts, so as to support and fix the strip plates 10 .

[0088] A plurality of strips 10 correspond to the feed plates 4 one by one, are arranged in parallel just above the feed trough 41, and are installed on adjacent support blocks 9; the strips 10 are used to press and limit the screws on the feed trough 41 to avoid separation due to vibration and ensure smooth flow of the screws.

[0089] A plurality of blocks 11 are installed one by one at the end of the strip 10 and are arranged directly above the transfer slot 741; the block 11 is L-shaped, and one end is installed at the end of the strip 10 through a connecting plate, wherein the block 11 and the connecting plate are connected by a linear groove and a bolt, so that the height of the block 11 can be conveniently adjusted, which is convenient for assembly and debugging.

[0090] Through the above arrangement, the screws in transit can be pressed and limited to prevent them from falling off due to vibration, thereby ensuring smooth flow of the screws, and the overall structure is stable and has a long service life.

[0091] In some embodiments, Figure 1 As shown, it includes: a reject plate 12 and a third driving member 13.

[0092] The rejecting plate 12 is vertically arranged above one end of the conveying plate 4 close to the screening plate 5, and a plurality of through openings 121 are provided at the bottom, and the through openings 121 correspond to and engage with the conveying plate 4 one by one.

[0093] The third driving member 13 is installed on the material storage box 2 and is in driving connection with the rejecting plate 12 for driving the rejecting plate 12 to reciprocate along the conveying plate 4 .

[0094] When the screws that exceed the specifications slide from the screening trough 51 to the material conveying trough 41, the third driving member 13 drives the rejection plate 12 to reciprocate along the material conveying plate 4. Therefore, the screws that exceed the specifications will not be able to pass through the through opening 121, and will be pushed out of the material conveying trough 41 by the rejection plate 12, causing it to fall back into the storage bin 21.

[0095] Through the above arrangement, abnormal screws can be filtered so that screws that exceed the specification are pushed back into the storage bin 21, thereby avoiding the situation where abnormal screws cause material jamming and flow into the assembly process.

[0096] Exemplarily, the first driving member 6, the second driving member 7A and the third driving member 13 are all small-diameter cylinders, which have the advantages of extremely low energy consumption and no noise pollution, and are convenient for practical use; but are not limited to this, and can also be servo electric cylinders, hydraulic cylinders or other driving members without specific limitation.

[0097] In some embodiments, Figure 3 As shown, the bottom of the storage bin 21 has a V-shaped groove 211 , and the contact surfaces of the feed plate 4 and the screening plate 5 are in the same vertical plane as the bottom edge of the V-shaped groove 211 .

[0098] Preferably, the screening channel 51 and the bottom slope of one side of the V-shaped groove 211 have the same inclination, so that the first slope 52 can be fully sunk into the screw pile, thereby improving the feeding effect.

[0099] Through the above arrangement, the V-shaped groove 211 can be used to gather the screws, thereby reducing accumulation, and the screws located at the bottom of the V-shaped groove 211 can be fed, thereby greatly improving the feeding efficiency and ensuring the feeding speed.

[0100] In some embodiments, Figure 5 As shown, the material conveying trough 41 is arranged obliquely, and one end of the material conveying trough 41 close to the transfer trough 741 is lower in height than the other end.

[0101] By setting the material conveying channel 41 tilted, the screws can slide down along the material conveying channel 41 by utilizing gravity during the vibration process, thereby significantly improving the material conveying efficiency.

[0102] In some embodiments, Figure 2 As shown, the top surface of the screening plate 5 has first inclined surfaces 52 on both sides of the screening channel 51 ; the top surface of one end of the conveying plate 4 close to the screening plate 5 has second inclined surfaces 42 on both sides of the conveying channel 41 .

[0103] By setting the first inclined surface 52, the screws that have not fallen into the screening channel 51 can be guided to slide off the top surface of the screening plate 5, and the second inclined surface 42 can be set to guide the screws that have not fallen into the feed channel 41 to slide off the top surface of the feed plate 4, which reduces the probability of material jamming and improves the conveying efficiency and operation stability.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details.
