[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0035] The preferred embodiment of the present invention is an in-mold automatic staple feeder, such as... Figure 1-12 As shown, the nail feeding machine includes a horizontally arranged guide trough body 10, a feeding mechanism 20 for loading workpieces 1000 into the guide trough body 10, a pushing mechanism 30 for pushing the workpieces 1000 located at the front end of the guide trough body 10 upward out of the guide trough body 10, a picking mechanism 40 for picking up the workpieces 1000 pushed out by the pushing mechanism 30, and a transfer mechanism 50 for driving the picking mechanism 40 to send the workpieces 1000 into the mold 2000. Specifically, the workpiece 1000 is cylindrical and has an annular step 1001 recessed on its upper outer side wall. The picking mechanism 40 is located above the guide trough body 10, and the transfer mechanism 50 is arranged parallel to the guide trough body 10. Through the cooperation of the transfer mechanism 50 and the picking mechanism 40, the present invention can transfer the workpiece on the guide trough body 10 to the corresponding position in the nail mold. Compared with the traditional method of manually placing the nail in the mold, the present invention is safer, lower in cost, more efficient, and has a higher yield.

[0036] In this embodiment, the pickup mechanism 40 includes a fixed clamping arm 401 and a movable clamping arm 402 arranged horizontally opposite each other. The pickup mechanism 40 also includes a suction nozzle 403 vertically disposed between the fixed clamping arm 401 and the movable clamping arm 402 for adsorbing workpieces. The pickup mechanism 40 further includes a first drive unit 404 that drives the movable clamping arm 402 horizontally away from or towards the suction nozzle 403. The first drive unit 404 is a cylinder, but it can also be a linear mechanism such as a lead screw motor or a motor rack module. By adsorbing the workpiece through the suction nozzle 403 while simultaneously clamping it with the fixed clamping arm 401 and the movable clamping arm 402, the stability of workpiece handling is doubled, preventing the workpiece from falling.

[0037] In this embodiment, the suction nozzle 403 includes a vertically arranged suction shaft 4031. The lower end of the suction shaft 4031 is provided with a suction groove 40311 for adsorbing the workpiece, which is adapted to the upper end of the workpiece. Specifically, a cylindrical boss 40312 adapted to the inner cavity of the workpiece is also provided in the center of the bottom surface of the suction groove 40311, which is used to seal the inner cavity of the workpiece and also serves to further position the workpiece. When the annular step 1001 at the upper end of the workpiece extends into the suction groove 40311, the fixed clamping arm 401 and the movable clamping arm 402 simultaneously clamp the lower outer wall of the workpiece. The bottom surface of the suction groove 40311 is provided with a positive pressure air passage 60 and a negative pressure air passage 70 located at both ends of the same diameter of the suction groove 40311. The negative pressure air passage 70 is used to connect to a negative pressure source when adsorbing the workpiece, thereby adsorbing and fixing the workpiece in the suction groove 40311. The positive pressure airway 60 is used to connect to the positive pressure source so that the workpiece can be quickly blown out of the adsorption tank 40311 by airflow when it is necessary to release the workpiece. The upper ends of both the positive pressure airway 60 and the negative pressure airway 70 penetrate the upper sidewall of the adsorption shaft 4031. The upper end of the adsorption shaft 4031 is provided with an air nozzle adapter 80 corresponding to the positive pressure airway 60 and the negative pressure airway 70 so as to connect to the air pipes of the negative pressure source and the positive pressure source respectively. The suction nozzle 403 also includes an air passage transition ring assembly 4032 disposed in the adsorption tank 40311. On the bottom surface of the air passage transition ring assembly 4032, a plurality of positive pressure air ports 322 and negative pressure air ports 323 are respectively provided for the positive pressure air passage 60 and the negative pressure air passage 70. The plurality of positive pressure air ports 322 and the plurality of negative pressure air ports 323 are arranged alternately in the circumferential direction. The air passage transition ring divides the negative pressure air passage 70 and the positive pressure air passage 60 into a plurality of positive pressure air ports 322 and negative pressure air ports 323 that are arranged alternately in a ring. This makes the workpiece circumferential pressure even during adsorption and release, and avoids the workpiece from being tilted and jammed.

[0038] In this embodiment, the airway transition ring assembly 4032 includes an upper air cushion 40321 and a lower air cushion 40322 that are stacked vertically. Multiple positive pressure air ports 322 and multiple negative pressure air ports 323 are evenly arranged in a ring on the upper surface of the lower air cushion 40322. An annular ventilation groove 90 is provided on the lower surface of the upper air cushion 40321 corresponding to the multiple annularly distributed positive pressure air ports. A positive pressure channel opening 100 is provided on the bottom surface of the annular ventilation groove 90 corresponding to the positive pressure airway 60. An arc-shaped connecting groove 110 communicating with the negative pressure airway 70 is provided on the upper surface of the upper air cushion 40321. Multiple negative pressure air pipes 120 are longitudinally arranged through the bottom surface of the arc-shaped connecting groove 110 corresponding to the multiple negative pressure air ports 323. The negative pressure air pipes 120 pass through the negative pressure air ports 323 and are flush with the bottom surface of the lower air cushion 40322. When picking up a workpiece, the negative pressure air passage 70 is connected to multiple negative pressure air pipes 120 through an arc-shaped connecting groove 110, thereby simultaneously adsorbing multiple positions on the upper end face of the workpiece, ensuring balanced force on the upper end of the workpiece during pickup and preventing tilting and jamming. When the workpiece is placed on the workstation inside the mold, multiple positive pressure air ports 322 and negative pressure air ports 323 are connected to the positive pressure air passage 60 through an annular ventilation groove 90 and positive pressure channel opening 100, thereby causing all negative pressure air ports 323 and positive pressure air ports 322 on the lower air pad 40322 to blow out high-pressure airflow, thus simultaneously blowing out various positions on the upper end of the workpiece, preventing jamming during material release.

[0039] In this embodiment, the picking mechanism 40 further includes a horizontally arranged movable support 405 and a lifting unit 406 for driving the movable support 405 to rise and fall. Specifically, the movable support 405 is a horizontally arranged horizontal plate, and a vertical plate 130 is vertically arranged on the movable terminal of the transfer mechanism 50. The horizontal plate is slidably arranged on the vertical plate 130. The lifting unit 406 is located on the movable terminal of the transfer mechanism 50. The first drive unit 404, the fixed clamping arm 401, and the suction nozzle 403 are all located on the movable support 405. Through the cooperation of the transfer mechanism 50, the lifting unit 406, and the first drive unit 404, the automated operation of picking up, feeding, and unloading workpieces can be realized, with high operational safety and efficiency. The lifting unit 406 is a cylinder, but it can also be a linear mechanism such as a lead screw motor or a motor rack module.

[0040] In this embodiment, the nail feeding machine also includes a limiting plate 140 disposed above the adsorption shaft 4031. The limiting plate 140 is connected to a movable bracket 405. A fixed seat 150 is provided on the movable bracket 405 below the limiting plate 140. The adsorption shaft 4031 is longitudinally slidably disposed on the fixed seat 150. A buffer spring 160 is coaxially disposed at the upper end of the adsorption shaft 4031, and the upper end of the buffer spring 160 abuts against the limiting plate 140. During the material picking and unloading process, the up-and-down movement of the adsorption shaft 4031 and the cooperation of the buffer spring 160 can prevent the adsorption shaft 4031 from colliding hard with the workpiece and causing damage to both.

[0041] In this embodiment, the ejector mechanism 30 includes a receiving seat 301 located at the front end of the guide trough body 10. The upper surface edge of the receiving seat 301 is provided with a stopping groove 3011 for the workpiece to slide into the guide trough body 10. A ejector hole 3012 is vertically provided through the bottom surface of the stopping groove 3011. The ejector mechanism 30 also includes an ejector shaft 302 passing through the ejector hole 3012, and an ejector drive unit 303 for driving the ejector shaft 302 to rise and fall. The ejector drive unit 303 is a cylinder, but can also be a linear mechanism such as a lead screw motor or a motor rack module. During operation, the ejector shaft 302 ejects the workpiece out of the stopping groove 3011, allowing the movable clamping arm 402 and the fixed clamping arm 401 to easily hold the lower end of the workpiece. When the ejector shaft 302 is not ejecting, the workpiece is ensured to remain completely within the stopping groove 3011, preventing it from falling.

[0042] In this embodiment, the transfer mechanism 50 includes a feeding guide rail 501 for the picking mechanism 40 to reciprocate toward the interior of the mold, and a feeding drive unit 502 for driving the picking mechanism 40 to move along the feeding guide rail 501. The feeding drive unit 502 is a cylinder, but it can also be a linear mechanism such as a motor rack and pinion module or a lead screw motor module. A slider 511 is provided on the feeding guide rail 501, and the picking mechanism 40 is mounted on the slider 511, with the slider forming the movable terminal of the feeding mechanism. Through the cooperation of the transfer mechanism 50, the movable bracket 405 can be driven to move rapidly between the workstation inside the mold and the workstation of the guide trough body 10, achieving efficient and safe material feeding.

[0043] In this embodiment, the feeding mechanism 20 is a vibratory feeder to achieve stable and efficient feeding.

[0044] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
