Abstract

This application relates to a bolt feeder, including a lifting and feeding module for lifting screws, a screening module for vibratingly screening screws, and a vibrating motor on the bottom surface of a feed trough. The vibrating motor vibrates the screws in the feed trough to the lifting and feeding module, while simultaneously receiving defective screws screened out by the screening module. The screws screened by the screening module enter a linear feeding module from the feeding track, which vibrates and supplies them to the next process. A take-up module removes the screws supplied by the linear feeding module one by one. The feeding track has a defective product redirection channel and a good product direct channel on both sides, creating a height difference. This causes large-headed screws to tilt towards the inclined hanging surface, thus securing the screws to one side of the connector. Screws that do not meet the position requirements will fall down into the defective product redirection channel in the middle of the track, without affecting normal screw feeding.

Description

Technical Field

[0001] This application belongs to the field of screw processing technology, and in particular relates to a bolt feeder. Background Technology

[0002] In industrial assembly, specially shaped screws are often used to connect components. Due to the unusual shapes of some screws, traditional feeders are prone to jamming or difficulty in feeding during the feeding process, which seriously affects the normal operation of the equipment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a bolt feeder to overcome the shortcomings of the prior art in that the feeding chuck is difficult to feed.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A bolt feeder, comprising:

[0006] The lifting and feeding module is used to lift screws.

[0007] The screening module is a vibratory screw screening module. It includes a connecting body, a screw feeding track, a redirecting plate, a guide plate, and a vibration platform. The vibration platform drives the connecting body to vibrate. The screw feeding track is located on the connecting body, with one end connected to the discharge end of the lifting and feeding module. The redirecting plate is installed in the middle of the screw feeding track, dividing it into a defective product redirection channel and a good product direct current channel. A space is formed between the redirecting plate and the good product direct current channel, allowing screws to pass through. The connecting body has an inclined hanging surface corresponding to this space, which easily retains screws. Both ends of the inclined hanging surface are twistedly connected to the screw feeding track. One end is used to twist and tilt the screws to create a height difference, facilitating the screening of screws of unqualified sizes. The other end lifts and straightens the screws to continue feeding. The defective product redirection channel is located opposite the connecting body to the inclined hanging surface, allowing screws that fail to hang on the inclined hanging surface to flow out through the defective product redirection channel. The guide plate is located above the end of the good product direct current channel to limit the movement space of the screws.

[0008] The material trough has a vibration motor installed on the bottom surface. The vibration motor vibrates the screws in the material trough and sends them to the lifting and feeding module, while receiving and screening the defective screws screened out by the receiving and screening module.

[0009] The linear feeding module, where the screws screened by the screening module enter the linear feeding module from the screw feeding track, and the linear feeding module vibrates to supply the next process.

[0010] The material handling module removes the screws supplied by the linear feeding module one by one.

[0011] Furthermore, the linear feeding module includes a second vibration platform, a vibrating feeding body, and a screw detection component. The vibrating feeding body has a feeding channel, one end of which is connected to the screw feeding track. The second vibration platform drives the vibrating feeding body to vibrate, and the screw detection component detects whether there are screws in the feeding channel.

[0012] Furthermore, the screw detection assembly includes an adjustable height bracket and two sensors. The adjustable height bracket is fixed on the vibrating feeder, and the two sensors are respectively installed on both sides of the adjustable height bracket. The two sensors are configured to detect the presence of screws from both directions of the feeding channel.

[0013] Furthermore, it also includes a pause feeding component, which includes a base, a drive cylinder, and a stop rod. The drive cylinder is mounted on the base, and the stop rod is mounted on the extended end of the drive cylinder. The stop rod is driven by the drive cylinder to extend into the feeding channel to prevent the screw from moving, or it can be retracted from the feeding channel without obstructing the movement of the screw.

[0014] Furthermore, the material handling module includes a linear motion component and two sets of clamping components. The linear motion component drives the two sets of clamping components to move and switch positions, and the two sets of clamping components clamp the screws in the feeding channel in sequence.

[0015] Furthermore, the linear motion component includes a linear module, and the two clamping components are two electric grippers that match the shape of the screw.

[0016] Furthermore, it also includes a linear drive assembly that moves the linear motion component. The linear drive assembly includes a linear guide and a moving cylinder. The linear guide is installed below the linear motion component, and the moving cylinder drives the linear motion component to move.

[0017] Furthermore, the lifting and feeding module includes a housing, two moving plates, two fixed plates, and a lifting cylinder. The two fixed plates are fixedly positioned inside the housing with a staggered vertical arrangement. One of the moving plates is located in the gap between the two fixed plates, and the other moving plate is located at the bottom front of the lower fixed plate. The lifting cylinder is installed on the back of the fixed plate and drives the two moving plates to move up and down.

[0018] Furthermore, the top surfaces of both moving plates and both fixed plates are inclined, and screws are fixed obliquely between the top of the adjacent moving plates and the fixed plates.

[0019] Furthermore, the housing and feed trough are tilted in a direction that facilitates screw feeding.

[0020] The beneficial effects of this invention are:

[0021] 1. The screw feeding track has a defective product reversing channel and a good product direct channel on both sides, which creates a height difference. This causes the large-headed screws to tilt towards the inclined hanging surface, so that the screws are stuck on one side of the connector. Screws that do not meet the position requirements will fall off the defective product reversing channel in the middle of the track, without affecting the normal screw feeding.

[0022] 2. The screw will return to a horizontal position after being restricted by the guide plate and lifted by the feeding track section at the rear of the feeding track. After passing through the linear feeding module, it will be clamped by two specially designed clamping components and transported to the next step. The feeding process is simple and easy to use.

[0035] Example

[0036] This embodiment provides a bolt feeder, including a lifting and feeding module 10, a screening module 20, a material trough 30, a linear feeding module 40, and a material picking module 50;

[0037] First, the screws are poured into the material trough 30. The bottom surface of the material trough 30 is equipped with a vibration motor 31. The vibration motor 31 vibrates the screws in the material trough 30 to the lifting and feeding module 10, and at the same time, it receives the defective screws screened out by the receiving and screening module 20.

[0038] Next, the screw is lifted by the lifting and feeding module 10, which is used to lift the screw. Optionally, it can be used to lift long strips or tubular lifting and feeding machines.

[0039] The screws lifted by the lifting feeder enter the screening module 20. The screening module 20 vibrates to screen the screws. The screening module 20 includes a connecting body 21, a screw feeding track 22, a redirecting plate 23, a guide plate 24, and a vibrating platform 25. The vibrating platform 25 is installed below the connecting body 21 and drives the connecting body 21 to vibrate. The screw feeding track 22 is located on the connecting body 21, allowing the screw head to be located on the connecting body 21, with the rest located on the screw feeding track 22. One end of the screw feeding track 22 is connected to the discharge end of the lifting feeder module 10. The redirecting plate 23 is installed in the middle of the screw feeding track 22. The redirecting plate 23 divides the screw feeding track 22 into a defective product redirection channel 26 and a good product direct channel 27. The redirecting plate 23 and the good product direct channel 27 are connected. A space is formed between the flow channels 26 to allow screws to pass through. The connector 21 has an inclined hanging surface 28 that is easy to retain the screws 21 in the space. The two ends of the inclined hanging surface 28 are twistedly connected to the screw feeding track 22. One end is used to twist and tilt the screw to form a height difference, which is convenient to screen out screws of unqualified size. The other end lifts the screw and straightens it to continue feeding. The defective product deflection channel 26 is set at the opposite position of the connector 21 and the inclined hanging surface 28, allowing screws that cannot be hung on the inclined hanging surface 28 to flow out from the defective product deflection channel 26. The guide plate 24 is set above the end of the good product direct flow channel 26 to limit the movable space of the screws, so that the screws can be straightened from the inclined hanging surface 28 and fed into the screw feeding track 22.

[0040] Screws that pass the screening by the screening module 20 enter the linear feeding module 40 from the screw feeding track 22. The linear feeding module 40 vibrates to feed the material picking module 50.

[0041] The linear feeding module 40 includes a second vibration platform 41, a vibrating feeding body 42, and a screw detection component 43. The vibrating feeding body 42 has a feeding channel 44, one end of which is connected to the screw feeding track 22. The second vibration platform 41 drives the vibrating feeding body 42 to vibrate, which vibrates and feeds the screws in the feeding channel 44 out. The screw detection component 43 detects whether there are screws in the feeding channel 44 so as to issue an alarm and replenish the screws in time.

[0042] The screw detection assembly 43 includes an adjustable height bracket 431 and two sensors 432. The adjustable height bracket 431 is fixed on the vibrating feeder 42. The two sensors 432 are respectively installed on both sides of the adjustable height bracket 431. The two sensors 432 are set accordingly to detect the presence of screws from both directions of the feeding channel, which is more accurate and clear.

[0043] It also includes a pause feeding component 45, which includes a base 451, a drive cylinder 452, and a stop rod 453. The drive cylinder 452 is mounted on the base 451, and the stop rod 453 is mounted on the extended end of the drive cylinder 452. The stop rod 453 is driven by the drive cylinder 452 to extend into the feeding channel 44 to prevent the screw from moving, or it can be retracted from the feeding channel 44 without obstructing the movement of the screw.

[0044] The material handling module 50 removes the screws supplied by the linear feeding module 40 one by one. The material handling module 50 includes a linear moving component 51 and two sets of clamping components 52. The linear moving component 51 drives the two sets of clamping components 52 to move and switch positions. The two sets of clamping components 52 clamp the screws in the feeding channel 44 in sequence. The linear moving component 51 includes a linear module. The two sets of clamping components 52 are two electric grippers. The electric grippers match the shape of the screws.

[0045] It also includes a linear drive assembly 53 that drives the linear motion assembly 51 to move. The linear drive assembly 53 includes a linear rail 531 and a moving cylinder 532. The linear rail 531 is installed below the linear motion assembly 51, and the moving cylinder 532 drives the linear motion assembly 51 to move.

[0046] As an embodiment of the present invention, the lifting and feeding module 10 may include a housing 11, two movable plates 12 that can move up and down, two fixed plates 13, and a lifting cylinder 14. The material trough 30 is installed outside the housing 11, and the two fixed plates 13 are fixed inside the housing 11 with a vertical offset. One movable plate 12 is located in the gap between the two fixed plates 13, and the other movable plate 12 is located at the bottom front of the lower fixed plate 13. The lifting cylinder 14 is installed on the back of the fixed plate 12. The lifting cylinder 14 drives the two movable plates 12 to move up and down. The screws in the material trough 30 roll into the lowest movable plate 12. The lifting cylinder 14 drives the movable plate 12 to be lifted to the fixed plate 13 at the middle, and then falls from the fixed plate 13 into the movable plate 12 at the middle. Then the lifting cylinder 14 drives the movable plate 12 at the middle to lift and send the screws into the outlet and finally into the screw feeding track 22.

[0047] The top surfaces of the two moving plates 12 and the two fixed plates 13 are all inclined, and the screws are fixed obliquely between the top of the adjacent moving plate 12 and the fixed plate 13.

[0048] The housing 11 and the feed trough 30 are inclined in a direction that is conducive to the feeding of screws, which makes it easier for the screws to fall into the feed trough 30 near the moving plate 12 under their own weight, and then the moving plate 12 lifts the screws.

[0049] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
