[0063] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0064] In some embodiments of this application, a screw distributor is proposed, which is connected to a linear vibrating feeder 500 to distribute screws output from the linear vibrating feeder 500.

[0065] The screw distributor includes a distribution base 100 and multiple distribution cylinders 200 assembled on the distribution base 100. The multiple distribution cylinders 200 are respectively connected to the locking nozzles of multiple locking mechanisms through air pipes.

[0066] The screw pick-and-place unit 300 is mainly used for picking up and placing screws.

[0067] The material distribution drive mechanism 330 is assembled on the material distribution base 100 and connected to the screw picking and placing unit 300. It drives the screw picking and placing unit 300 to move and change its position to perform material picking or placing operations.

[0068] Specifically, the material distribution base 100 is provided with a material inlet 110 and a material receiving part 170 for accommodating the direct vibration feeder 500. The material receiving part 170 is a material receiving notch, which is formed by recessing from the material distribution base 100. The material inlet 110 and the material receiving part 170 are connected.

[0069] The direct vibration feeder 500 extends into the material receiving section 170 near the direct vibration discharge port. The direct vibration discharge port and the material receiving port 110 above it are positioned correspondingly and connected to the material receiving port 110.

[0070] The screw output from the direct vibratory feeder 500 enters the feed port 110. When setting it up, the width of the direct vibratory feeder 500's output port can be set to be greater than the width of the feed port 110.

[0071] Multiple material distribution cylinders 200 are provided and assembled on the material distribution base 100. Each material distribution cylinder 200 is provided with a discharge port 210 for inserting screws. The material distribution cylinder 200 is connected to the locking nozzle of the locking mechanism through an air pipe for conveying the screws that have entered into it to the corresponding locking nozzle of the locking mechanism.

[0072] In some embodiments of this application, a feeding sensing element 120 is provided at the location corresponding to the feeding port 110 to detect whether there is material at the feeding port 110. The feeding sensing element 120 is a feeding sensing sensor.

[0073] In some embodiments of this application, the screw dispenser includes a screw picking and placing unit 300, which includes a screw picking and placing base 310 and a screw picking and placing component 320.

[0074] Multiple screw pick-and-place components 320 are provided and assembled side by side on the screw pick-and-place base 310, with the same spacing between adjacent screw pick-and-place components 320.

[0075] The screw pick-and-place component 320 can reciprocate along a first direction relative to the screw pick-and-place base 310 to pick up screws at the pick-up port 110 and place screws at the discharge port 210.

[0076] The screw pick-and-place component 320 can move relative to the screw pick-and-place base 310 in a first direction. The first direction reciprocating movement includes an extension movement near the pick-and-place port 110 and a retraction movement away from the place-and-place port 210.

[0077] The screw pick-and-place component 320 can pick up screws from the pick-and-place port 110 by extending it into the pick-and-place port 110.

[0078] It can retract and release screws from the discharge port 210 by moving relative to the discharge port 210.

[0079] The material dispensing drive mechanism 330 is connected to the screw pick-and-place base 310 and is used to drive the screw pick-and-place base 310 to reciprocate relative to the material dispensing base 100 along the second direction so that the multiple screw pick-and-place components 320 switch positions between the pick-and-place port 110 and the multiple discharge ports 210, wherein the first direction is perpendicular to the second direction.

[0080] When the material distribution drive mechanism 330 is activated, it can drive the screw pick-and-place base 310 and the multiple screw pick-and-place components 320 above it to move synchronously along the second direction. When the multiple screw pick-and-place components 320 move back and forth along the second direction, they will move sequentially to the material pick-up port 110 so that they can pick up materials from the material pick-up port 110. They can also move to the multiple material discharge ports 210 respectively so that they can place screws.

[0081] In some embodiments of this application, the screw picking and placing component 320 has a picking mode, a conveying mode, and a placing mode;

[0082] When the screw picking and placing component 320 is in the picking mode, the picking part 321 moves closer to the picking port 110 to pick up the screw at the picking port 110;

[0083] When the screw picking and placing component 320 is in the material conveying mode, the screw picking and placing component 320 moves from the material picking port 110 to the material dispensing port 210 along the wall of the material dispensing base 100 under the drive of the material dispensing drive mechanism 330.

[0084] When the screw pick-and-place component 320 is in the feeding mode, it moves in a direction away from the feeding port 210 so that the screw slides into the guide limit portion 230 and slides into the dispensing cylinder 200 along the guide limit portion 230.

[0085] In this embodiment, the screw distributor is equipped with a distribution drive mechanism 330. The distribution drive mechanism 330 drives multiple screw picking and placing components 320 to reciprocate along the second direction, thereby switching the positions of the multiple screw picking and placing components 320 between the picking port 110 and the multiple placing ports 210. This allows the multiple screw picking and placing components 320 to move to the picking port 110 respectively and to move to the corresponding placing port 210 after picking up the screw. This realizes the switching of the screw picking components between the picking port 110 and the placing port 210.

[0086] The screw pick-and-place component 320 is configured to be relative to the screw pick-and-place base 310, so that it can perform screw pick-and-place and screw placement actions by reciprocating relative to the screw pick-and-place base 310 along a first direction.

[0087] The automatic feeding of screws is achieved by the cooperation of the screw picking and placing component 320 and the powder driving mechanism. Multiple screw picking and placing components 320 pick up materials from the feeding port 110 and move them to their corresponding feeding port 210, so that multiple screws can be fed at one time, which meets the screw fastening requirements of the multi-fastening mechanism.

[0088] In some embodiments of this application, there are two discharge ports 210, which are respectively arranged on both sides of the feed port 110. The discharge port 210 located on the left side of the discharge port 210 is the first discharge port 210, and the discharge port 210 located on the right side of the discharge port 210 is the second discharge port 210.

[0089] Two screw-picking and placing components 320 are provided and are slidably connected to the screw-picking and placing base 310.

[0090] The screw pick-and-place component 320 located on the left is the first screw pick-and-place component 320, and the one on the right is the second screw pick-and-place component 320.

[0091] The material distribution drive mechanism 330 has an extended state and a retracted state;

[0092] When the material distribution drive mechanism 330 is in the retracted state, one of the screw picking and placing components 320 picks up material at the picking port 110, and the other screw picking and placing component 320 places material at the discharging port 210.

[0093] When the material distribution drive mechanism 330 is in the extended state, the material picking screw component 320 is at the material dispensing port 210 to dispense material, and the material picking screw component 320 is at the material picking port 110 to pick up material.

[0094] The material dispensing drive mechanism 330 is a material dispensing drive cylinder, which is connected to the pick-and-place screw base 310 through a cylinder rod.

[0095] The first direction is the front-to-back direction, and the second direction is the left-to-right direction.

[0096] When the material distribution drive cylinder retracts, the second pick-and-place screw component 320 is at the material pick-and-place port 110 and extends forward to pick up the material, while the first pick-and-place screw component 320 is at the first material discharge port 210 and moves backward to discharge the material. After the material is picked up, the cylinder rod extends, and the second pick-and-place screw component 320, having picked up the material, moves to the second material discharge port 210 and moves backward to discharge the material. The first pick-and-place screw component 320 moves from the first material discharge port 210 to the material pick-and-place port 110 and moves forward to pick up the material. The material is picked up and placed by continuously reciprocating in the left-right direction and reciprocating in the front-back direction.

[0097] In some embodiments of this application, the screw dispenser further includes a screw pick-and-place drive 340, which is connected to the screw pick-and-place component 320 and drives the screw pick-and-place component 320 to move to pick up and place screws.

[0098] The screw pick-and-place drive unit 340 is a screw pick-and-place drive cylinder, which is connected to the screw pick-and-place component 320 and drives the screw pick-and-place component 320 to perform telescopic movements.

[0099] Multiple screw pick-and-place drive units 340 are provided, each connected to a multiple screw pick-and-place component 320, so as to achieve the effect of driving multiple screw pick-and-place components 320 individually.

[0100] In some embodiments of this application, the screw mounting base 310 includes:

[0101] First matrix 311;

[0102] The second base is fixedly mounted on the first base 311, and the screw pick-and-place drive 340 and the guide rail for moving the screw pick-and-place component 320 are mounted on the second base.

[0103] The second substrate includes a second substrate 312 and a bending plate 313, one end of which is connected to the top of the second substrate 312 and the other end is connected to the screw drive 340.

[0104] The guide rail is disposed within the second substrate 312.

[0105] In some embodiments of this application, a sliding connection assembly is provided between the material distribution base 100 and the first base 311. The sliding connection assembly includes a sliding block 420 connected below the first base 311 and a sliding track 430 connected on the material distribution base 100. The material distribution drive mechanism 330 is connected to the first base.

[0106] The material distribution drive mechanism 330 drives the first base 311 to slide along the material distribution base 100, causing the second base connected to the first base 311, as well as the screw picking and placing component 320 and the screw picking and placing drive component 340 assembled on the second base, to slide relative to the material distribution base 100, thereby realizing the change of position of multiple screw picking and placing components 320.

[0107] In some embodiments of this application, a limiting component 410 is disposed on the material distribution base 100 at both sides of the second base, and is used to limit the movement position of the screw pick-up and put-down base 310.

[0108] The limiting component 410 is a limiting block, which is fixed on the material distribution base 100 to limit the left and right movement of the screw picking and placing unit 300.

[0109] In some embodiments of this application, the end of the screw pick-and-place component 320 is recessed to form a material pick-and-place portion 321, and a limiting portion 322 is formed at the end of the screw pick-and-place component 320 opposite to the material pick-and-place portion 321.

[0110] The material handling section 321 is a material handling groove formed at the end of the screw handling component 320, which can be used to clamp materials.

[0111] The limiting part 322 is a limiting protrusion. When the screw picking and placing component 320 slides along the picking guide rail, the limiting part 322 above it can abut against the second base plate 312 to limit the movement position of the screw picking and placing component 320 relative to the screw picking and placing base 310.

[0112] In some embodiments of this application, a plurality of mounting portions are formed on the material distribution base 100, and a material distribution cylinder 200 is assembled in each of the mounting portions. The mounting portion is a mounting groove formed on the material distribution base 100, and the material distribution cylinder 200 is inserted into the mounting groove during assembly.

[0113] A notch 220 is formed on the dispensing cylinder 200 for inserting the screw pick-and-place component 320; and

[0114] A guide limiting part 230 is formed on the material distribution cylinder 200 segment opposite to the notch part 220. The guide limiting part 230 is located above the discharge port 210 and is used to cooperate with the screw picking and placing component 320 during material feeding to guide the screws carried on the screw picking and placing component 320 into the discharge port 210.

[0115] The notch 220 is used to avoid the screw picking and placing component 320, so that the screw picking and placing component 320 can extend into the material dispensing cylinder 200 to release the material into the discharge port 210.

[0116] The guide limit part 230 is used to limit and guide the screw as it is lowered. It is opposite to the notch part 220. When the screw picking and placing part 320 extends into the notch part 220 and releases the screw, it can slide down along the guide limit part 230 to the discharge port 210 located at the lower position. This ensures that the screw will not deviate from its path during the downward movement and can slide smoothly to the discharge port 210 and enter the interior of the dispensing cylinder 200.

[0117] In some embodiments of this application, the dispensing cylinder 200 includes a dispensing outer cylinder 251 and a dispensing inner cylinder 252. The dispensing inner cylinder 252 is disposed through the dispensing outer cylinder 251 from top to bottom, and its bottom extends out from the bottom of the dispensing outer cylinder 251 for connection to the user and the air pipe.

[0118] A first notch 220 is provided above the material distribution outer cylinder 251. An outer cylinder slide section and an air nozzle mounting section 240 are formed on the material distribution outer cylinder 251 at the position corresponding to the first notch 220.

[0119] The first notch 220 is a first notch formed on the outer cylinder 251, the outer cylinder sliding part is an outer cylinder sliding channel formed at a position opposite to the first notch, and the air nozzle mounting part 240 is formed at the lower position of the outer cylinder 251 and is an air nozzle mounting groove for mounting the air nozzle.

[0120] A second notch 220 is formed above the inner material distribution cylinder 252. A guide limiting part 230 is formed on the inner material distribution cylinder 252 at the location corresponding to the second notch 220. The guide limiting part 230 is adapted to the contour of the outer cylinder slide and fits the outer cylinder slide.

[0121] The second notch 220 is a second notch formed on the inner material distribution cylinder 252, and the guide limiting part 230 is a guide limiting slide groove that fits the outer cylinder sliding channel. The second notch and the first notch form the notch 220.

[0122] When set up, the guide limiting part 230 is set as an arc-shaped guide limiting groove, which extends from top to bottom along the height direction of the distributing cylinder 200.

[0123] An air nozzle, connected to an air blowing device, is obliquely mounted inside the air nozzle mounting part 240 and communicates with the material distributing inner cylinder 252, and is used to drive the screw in the material distributing inner cylinder 252 to move.

[0124] The air blowing device adopts an existing structure, which is connected by an air pipe and an air blowing nozzle to transmit airflow to the inside of the material distribution inner cylinder 252 to drive the screw inside the material distribution inner cylinder 252 to move.
