Description

Technical Field

[0001] This utility model relates to the field of precision screw manufacturing technology, and in particular to an automatic feeding device for precision screw manufacturing. Background Technology

[0002] Precision screws are screws with high manufacturing precision, small dimensional tolerances, excellent materials, and fine surface treatment. They are typically used in fields with strict requirements for fasteners, such as electronic products, precision instruments, medical devices, aerospace, and the automotive industry.

[0003] Referring to the patent document with application number "CN202020569668.9" entitled "An Automatic Feeding Device for Precision Screw Production", this patent document uses a cleaning brush at the lower end of the feeding hopper to clean the dust and debris on the surface of the metal blank, preventing the dust and debris on the surface of the blank from affecting the production of screws, which is conducive to improving the production precision of screws. The waste collection mechanism can facilitate workers to collect unqualified blanks and waste materials when the device is in use, thereby improving the efficiency of the device.

[0004] Existing technology uses cleaning brushes suspended in the feed hopper to clean metal debris from the screw surface. While this effectively prevents screws from being cleaned inside the feed hopper and reduces the number of screws carrying metal debris, the cleaning brushes are vertically positioned at the feed hopper's outlet. Screws fall from the feed hopper onto the cleaning brushes, which can damage the brushes over time. Furthermore, multiple screws colliding and falling together can quickly pass over the cleaning brushes, resulting in many screws not being effectively cleaned and affecting subsequent processing.

[0005] To address this, we designed an automatic feeding device for the production of precision screws. Utility Model Content

[0006] The purpose of this invention is to provide an automatic feeding device for the production of precision screws, which addresses the problem of low cleaning efficiency in existing technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automatic feeding device for precision screw production includes a base, a support seat disposed on top of the base, a feeding assembly disposed on top of the support seat, and a conveyor disposed on top of the base; and further includes:

[0009] The cleaning assembly includes a rotating drum, a plurality of hard-bristled brushes arranged in a ring inside the rotating drum, a wiping body and a wiping strip, a support plate on top of the base, a bracket on top of the support plate, and a vacuuming component on top of the bracket.

[0010] An anti-clogging component is provided on both sides of a guide body located at the top of the conveyor.

[0011] Preferably, the feeding assembly includes a vibrator disposed on top of the support base and a screw input pipe disposed at an incline on top of the vibrator, the output end of the screw input pipe being connected to the rotating drum.

[0012] Preferably, the anti-clogging component includes push blocks disposed on both sides of the guide body, a traction rod disposed on the inner wall of the guide body for pulling the push blocks, a push rod disposed on the top of the push blocks, and drive rods symmetrically disposed at the bottom of the vacuuming component.

[0013] Preferably, the end of the rotating drum away from the vibrator is provided with a drive assembly, which includes a first gear disposed at the end of the rotating drum away from the vibrator, a first motor disposed on the side wall of the support base, and a second gear disposed on the output shaft of the first motor and meshing with the first gear.

[0014] Preferably, the sidewall of the support plate is provided with a plurality of second motors, and the output shafts of the plurality of second motors are respectively connected to the end of the transmission roller on the inner side of the conveyor.

[0015] Preferably, the inner wall of the guide body is provided with a plurality of irregularly arranged auxiliary rods.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the setting of a rotating drum and a hard brush, ensures that when the screw in the screw input tube is about to roll into the conveyor, the screw will first come into contact with the hard brush and multiple wiping bodies, reducing the metal debris attached to the screw. At the same time, the continuous rotation of the drum can prevent the screw from getting stuck and causing blockage. In addition, the connection between the rotating drum and the screw input tube and the conveying method can effectively prevent the screw from being unable to complete the cleaning work due to excessive speed. Compared with the prior art, it can effectively reduce the cleaning process due to excessive screw speed, and improve the cleanliness of the screw before entering the conveyor.

[0018] 2. This utility model, through the setting of the guide body and push rod, ensures that the screws fall correctly into the conveyor after the cleaning process, preventing the screws from being thrown out of the conveyor's transport range due to the rotational force of the drum. It also avoids increasing the waste of workers picking up the screws. In order to prevent the screws from being stuck on the guide body under the action of force, the push rod pushes the screws within the effective working area, which can effectively reduce the phenomenon of screws being stuck on the guide body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 An automatic feeding device for precision screw production includes a base, a support seat on top of the base, a feeding assembly on top of the support seat, and a conveyor 4 on top of the base. It also includes a cleaning assembly and an anti-clogging assembly. The cleaning assembly includes a rotating drum 101, a plurality of hard brushes 103 arranged in a ring inside the rotating drum 101, a wiping body 104 and a wiping strip 105, a support plate 3 on top of the base, a bracket on top of the support plate 3, and a dust collection component 301 on top of the bracket. The conveyor 4 has a guide body 5 on top, and the anti-clogging assembly is located on both sides of the guide body 5. The feeding assembly includes a vibrator 1 on top of the support seat and a screw input pipe 102 inclined on top of the vibrator 1. The output end of the screw input pipe 102 is connected to the rotating drum 101.

[0027] Before feeding the screws, a simple cleaning of metal debris is required. The screws are first placed in the screw input pipe 102, and then vibrated by the vibrator 1, causing them to roll along the inclined screw input pipe 102 into the rotating drum 101. Normal screw conveying is mainly achieved through the vibration of the vibrator 1, which is a conventional vibrating device driven by an external power supply. It primarily conveys the screws through vibration, which loosens metal debris on the screw surface and prevents the screws from being damaged by excessive impact during falling. The cleaning process is omitted. The rotating drums 101 are arranged horizontally on one side of the vibrator 1. The rotating drums 101 mainly cause the screws to rub repeatedly inside by rotating, causing metal debris on the screw surface to fall off and be collected by the rotating drums 101 for later unified cleaning. After the screws have been cleaned, the conveyor 4 at the bottom of the rotating drums 101 completes the feeding process. In order to reduce the speed and direction of the screws falling from the rotating drums 101, the semi-circular open guide body 5 can effectively reduce the kinetic energy of the screws during the falling process. After the kinetic energy of the screws is dissipated, the guide body 5 can effectively reduce the kinetic energy of the screws during the falling process. The screws smoothly fall onto the conveyor 4 to complete the loading process. The cleaning components inside the rotating drum 101 improve the cleaning efficiency of the screw surface under the support of rotation, reducing the situation where the screws carry metal debris. At the same time, the guide body 5 mainly reduces the kinetic energy of the screws falling, and the anti-clogging component mainly prevents the screws from losing kinetic energy and remaining on their surface, instead of slipping onto the conveyor 4. The interior of the rotating drum 101 is mainly composed of multiple hard brushes 103, wiping bodies 104, and wiping strips 105. The hard brushes 103 are cleaning components with relatively hard and upright bristles in the prior art, and they are arranged in a ring on the rotating drum. Inside the drum 101, the wiping body 104 is a wiping cloth used for wiping metal materials in the prior art. The wiping cloth is made of fiber material and is fixed inside the drum 101 by stacking. The wiping strips 105 arranged on the wiping body 104 are existing wiping sticks, which are made of sponge material. In order to avoid the phenomenon of screw debris flying during the cleaning process, the dust collection component 301 symmetrically arranged on the side wall of the drum 101 can effectively reduce the flying debris and the dust carried by the screw. The dust collection component 301 is a small vacuum cleaner in the prior art.

[0028] The anti-clogging component includes push blocks 501 disposed on both sides of the guide body 5, a traction rod 502 disposed on the inner wall of the guide body 5 for pulling the push blocks 501, a push rod 503 disposed on the top of the push blocks 501, and a drive rod 302 symmetrically disposed at the bottom of the vacuuming component 301.

[0029] When screws become stuck on the guide body 5, both guide bodies 5 are provided with grooves. The push block 501 and the push rod 503 on top of the push block 501 set in the groove can scrape off the surface of the guide body 5 uniformly, reducing the phenomenon of screws getting stuck. At the same time, in order to reduce the possibility of the push block 501 falling off or deviating from the sliding direction, the traction rod 502 set inside the groove can effectively pull the push block 501 to move, further improving the sliding direction of the push rod 503. In order to reduce the need for manual intervention to resolve the problem of screws getting stuck, the drive rods 302 symmetrically set at the bottom of the vacuuming component 301 can improve the pushing efficiency of the push block 501, allowing the operator to drive the push block 501 and the vacuuming component 301 away from the device.

[0030] It should be noted that when a stuck screw appears on the guide body 5, the drive rod 302 will be activated to slide in the groove.

[0031] In addition, the vibrator 1 is provided with a screw input pipe 102, which is connected to the rotating drum 101. The screw input pipe 102 is the pipe through which screws enter the output range of the vibrator 1 and the rotating drum 101. It is connected to the screw storage mechanism. The end of the screw input pipe 102 away from the vibrator 1 is inserted into the rotating drum 101 and does not rotate with the rotating drum 101.

[0032] A drive assembly is provided at the end of the rotating drum 101 away from the vibrator 1. The drive assembly includes a first gear 106 disposed at the end of the rotating drum 101 away from the vibrator 1, a first motor 2 disposed on the side wall of the support base, and a second gear 107 disposed on the output shaft of the first motor 2 and meshing with the first gear 106.

[0033] Since the rotating drum 101 is a screw cleaning component, it needs to rotate to clean the metal debris on the screw surface. The first gear 106 fixedly installed on the back side of the rotating drum 101 is existing technology and rotates synchronously with the rotating drum 101. The first motor 2 set next to the vibrator 1 is existing equipment and is driven by an external power supply. The second gear 107 set at the output shaft of the first motor 2 meshes with the first gear 106, so that the rotating drum 101 can rotate on the screw input tube 102.

[0034] The support plate 3 has several second motors on its side wall, and the output shafts of the second motors are respectively connected to the ends of the transmission rollers inside the conveyor 4. When the second motors are started, they drive the transmission rollers inside the conveyor 4 to rotate, which in turn drives the conveyor belt to move, making it easier to transport the screws that fall onto the conveyor 4.

[0035] The inner wall of the guide body 5 is provided with a number of irregularly arranged auxiliary rods 504; the auxiliary rods 504 mainly prevent the screws, whose kinetic energy is not reduced by the guide body 5, from having their kinetic energy reduced by the auxiliary rods 504.

[0036] The working principle of this utility model is as follows:

[0037] After the staff connects the screw storage device to the screw input pipe 102, the first motor 2 is started to rotate the drum 101. The cleaning components on the inner wall of the drum 101 are arranged correctly. The screws then enter the output range of the vibrator 1 through the screw input pipe 102 and move to the drum 101 in the form of vibration. After the screws have finished cleaning, they fall to the guide body 5 under the continuous rotation of the drum 101. The screws fall into the conveyor 4 when the impact energy is reduced by the guide body 5. The screws that are stuck in the guide body 5 due to loss of kinetic energy need to be driven by the drive rod 302 on the second motor. With the drive rod 302 driving the push rod 503, the screws stuck in the guide body 5 are pushed onto the conveyor 4. The setting of the drum 101 and the hard brush 103 can effectively improve the cleaning of metal debris on the surface of the screws, thereby improving the cleanliness of the screws entering the conveyor 4.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
