Description

Technical Field

[0001] This invention relates to the technical field of bolt processing, and specifically to a pre-cleaning device for bolt processing. Background Technology

[0002] Bolts are frequently used in electronic products, mechanical equipment, and digital products. To ensure product quality, bolts often need to be cleaned using pre-cleaning equipment.

[0003] According to patent application CN202111567237.4, a bolt processing cleaning device with pre-cleaning function is disclosed. This cleaning device includes a base, a cleaning mechanism, and a loading pre-cleaning mechanism. The base is equipped with a vertical rod and a drive mechanism for rotating the vertical rod. Multiple circumferentially distributed connecting rods are mounted on the vertical rod, and each connecting rod is connected to a cleaning cylinder. The base has loading and cleaning stations arranged sequentially along the rotation direction of the vertical rod. The loading pre-cleaning mechanism is located at the loading station and is used to pre-clean the workpiece and load the pre-cleaned workpiece into the cleaning cylinder at the loading station. The cleaning mechanism is located at the cleaning station and is used to clean the workpiece inside the cleaning cylinder at the cleaning station. This invention provides a bolt processing cleaning device with pre-cleaning function, which can classify and clean bolts, making the bolt cleaning more thorough.

[0004] The above-mentioned bolt cleaning device has a pre-cleaning function and can classify and clean bolts. Traditional bolt cleaning devices often use a cleaning cylinder to hold the bolts for cleaning, but the cleaning cylinder lacks the ability to organize the bolts, making it difficult to clean the bolts evenly. Summary of the Invention

[0005] The present invention mainly provides a pre-cleaning device for bolt processing to solve the technical problems mentioned in the background art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A pre-cleaning device for bolt processing includes a cleaning tank, wherein a material conveying and cleaning mechanism is provided inside the cleaning tank, and an auxiliary cleaning mechanism is provided outside the cleaning tank.

[0008] The material conveying and cleaning mechanism includes a support base installed inside the cleaning tank, a rotating disk rotatably connected to the top of the support base, a connecting rod installed on the outer surface of the rotating disk and surrounding the rotating disk, and a bolt straightening assembly connected to the end of the connecting rod away from the support base.

[0009] The bolt straightening assembly includes a vibratory plate installed on the end of the connecting rod away from the rotating disk, a spiral rising ramp installed inside the top of the vibratory plate, and a return rail installed at the discharge end of the spiral rising ramp.

[0010] The bolt straightening assembly also includes a first ultrasonic vibrator installed on the top of the vibratory plate, and a plurality of second ultrasonic vibrators disposed between the lower surface of the spiral ramp and the inner wall of the top of the vibratory plate. The plurality of second ultrasonic vibrators are installed on the lower surface of the spiral ramp and are arranged along the spiral ramp.

[0011] Furthermore, the material conveying and cleaning mechanism also includes a rotary joint installed on the upper surface of the rotating disk and inserted into the rotating disk. The liquid outlet end of the rotary joint is connected to a water outlet pipe, and one end of the water outlet pipe extending into the vibrating disk is connected to a water spray head. In this invention, water is supplied to the water outlet pipe through the rotary joint, and the water outlet pipe sprays water through the water spray head so that the fluid descends along the spiral ascending ramp, so that the bolts on the spiral ascending ramp are immersed in the water.

[0012] Furthermore, the auxiliary cleaning mechanism includes a discharge assembly, a brushing assembly, and a feed assembly arranged around the cleaning tank. The brushing assembly includes a first base mounted on one side surface of the cleaning tank and a first hydraulic cylinder mounted on the upper surface of the first base. The piston rod of the first hydraulic cylinder is connected to a lifting frame, and a motor is connected to the upper surface of the lifting frame. The output shaft of the motor passes through the lifting frame and is connected to a brush head. In this invention, the motor drives the brush head to rotate, and the brush head enters the vibratory plate to clean the bolts inside the vibratory plate.

[0013] Furthermore, the feeding assembly includes a support cylinder installed on the outer surface of the cleaning tank and a material cylinder installed on the upper surface of the support cylinder. A discharge ladder is installed at the bottom of the outer surface of the material cylinder. In this invention, the support cylinder provides support for the material cylinder, the material cylinder collects bolts, and the discharge ladder guides the bolts inside the material cylinder to be discharged.

[0014] Furthermore, the discharge assembly includes a second base mounted on the outer surface of the cleaning tank, a second hydraulic cylinder mounted on the upper surface of the second base, and a magnetic separation conveyor belt mounted on the piston rod of the second hydraulic cylinder. In this invention, the magnetic separation conveyor belt extends into the vibrating plate to adsorb and transport the bolts inside the vibrating plate, thereby discharging the cleaned bolts.

[0015] Furthermore, a first outlet pipe is connected to the bottom of the cleaning tank, and a filter is connected to the end of the first outlet pipe away from the cleaning tank. A second outlet pipe is connected to the outlet end of the filter, and the end of the second outlet pipe away from the filter extends to the top of the inside of the cleaning tank. In this invention, the filtered cleaning liquid enters the second outlet pipe under the action of the pump. Since the second outlet pipe extends to the top of the inside of the cleaning tank, the cleaning liquid inside the cleaning tank can be recycled.

[0016] Furthermore, a spiral baffle is installed at one end of the upper surface of the spiral ramp, and the upper surface of the spiral ramp is provided with anti-slip texture. In this invention, the anti-slip texture increases the friction between the bolt and the spiral ramp, which facilitates the conveying of the bolt in the vibratory feeder.

[0017] Furthermore, the bolt straightening assembly also includes multiple liquid guide tubes passing through the top housing of the vibratory feeder. One end of the liquid guide tube extends into the interior of the vibratory feeder and penetrates the housing of the spiral ramp. In this invention, excess cleaning fluid in the vibratory feeder is discharged through the liquid guide tubes to prevent excessive cleaning fluid from increasing the buoyancy of the bolts in the vibratory feeder and affecting the bolt conveying.

[0018] Furthermore, the lower surface of the vibratory feeder is equipped with multiple casters, and the vibratory feeder is slidably connected to the inner wall of the cleaning tank through the casters. In this invention, the vibratory feeder slides on the inner wall of the cleaning tank through the casters at its bottom end to reduce friction between the vibratory feeder and the inner wall of the cleaning tank.

[0019] Furthermore, the bottom of the inner end of the material cylinder is provided with an inclined surface. In this invention, the material cylinder guides the bolts inside to concentrate through its bottom inclined surface, so that the bolts can be concentrated near the discharge ladder to facilitate the discharge of the bolts.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] Firstly, this invention can guide the arrangement of bolts during the bolt cleaning process to facilitate cleaning and improve cleaning efficiency. Specifically, the bolts not only rise continuously through the spiral ramp on the vibrating plate, causing the miscellaneous bolts to be arranged on the spiral ramp for sorting, but also the first ultrasonic vibrator cleans the miscellaneous bolts concentrated at the bottom of the vibrating plate, and the second ultrasonic vibrator cleans the bolts on the spiral ramp.

[0022] Secondly, this invention can drive the vibratory feeder through the feeding assembly, the washing assembly, and the discharging assembly in sequence. The bolts inside the material cylinder are guided out by the discharge ladder. The first hydraulic cylinder drives the lifting frame to rise, so that the lifting frame drives the motor on it to rise and fall. The brush head enters the vibratory feeder to clean the bolts inside the vibratory feeder. The second hydraulic cylinder drives the magnetic separation conveyor belt to rise and fall, so that the magnetic separation conveyor belt extends into the vibratory feeder to attract and transport the bolts inside the vibratory feeder, thereby discharging the cleaned bolts to facilitate the circulation and cleaning of bolts in the vibratory feeder.

[0023] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0036] For an example, please refer to the appendix. Figure 1-8 A pre-cleaning device for bolt processing includes a cleaning tank 10, with a material conveying and cleaning mechanism 20 inside the cleaning tank 10 and an auxiliary cleaning mechanism 30 outside the cleaning tank 10.

[0037] The material conveying and cleaning mechanism 20 includes a support base 21 installed inside the cleaning tank 10, a rotating disk 23 rotatably connected to the top of the support base 21, a connecting rod 22 installed on the outer surface of the rotating disk 23 and arranged around the rotating disk 23, and a bolt straightening assembly 24 connected to the end of the connecting rod 22 away from the support base 21.

[0040] For details, please refer to the appendix.

The piston rod of the first hydraulic cylinder 322 is connected to a lifting frame 323. A motor 324 is connected to the upper surface of the lifting frame 323. The output shaft of the motor 324 passes through the lifting frame 323 and is connected to a brush head 325.

[0042] The feeding assembly 33 includes a support cylinder 331 installed on the outer surface of the cleaning tank 10, and a material cylinder 332 installed on the upper surface of the support cylinder 331. A discharge ladder 333 is installed at the bottom of the outer surface of the material cylinder 332.

[0043] The discharge assembly 31 includes a second base 311 installed on the outer surface of the cleaning tank 10, a second hydraulic cylinder 312 installed on the upper surface of the second base 311, and a magnetic separation conveyor belt 313 installed on the piston rod of the second hydraulic cylinder 312.

[0044] It should be noted that in this embodiment, water is supplied to the outlet pipe 26 through the rotary joint 25, and the outlet pipe 26 sprays water through the spray head 27 so that the fluid descends along the spiral ramp 242 so that the bolts on the spiral ramp 242 are immersed in the water.

[0045] Furthermore, the first base 321 provides support for the first hydraulic cylinder 322, and the first hydraulic cylinder 322 drives the lifting frame 323 to rise, so that the lifting frame 323 drives the motor 324 on it to rise and fall, and the motor 324 drives the brush head 325 to rotate, and the brush head 325 enters the vibrating plate 241 to clean the bolts inside the vibrating plate 241.

[0046] Furthermore, the support cylinder 331 provides support for the material cylinder 332, the material cylinder 332 collects the bolts, and the discharge ladder 333 guides the bolts inside the material cylinder 332 to be discharged.

[0047] Furthermore, the second base 311 provides support for the second hydraulic cylinder 312, and the second hydraulic cylinder 312 drives the magnetic separation conveyor belt 313 to rise and fall, so that the magnetic separation conveyor belt 313 extends into the vibrating plate 241 to adsorb and transport the bolts in the vibrating plate 241, thereby discharging the cleaned bolts.

[0048] For details, please refer to the appendix. Figure 4 and 7 The bottom end of the cleaning tank 10 is connected to a first outlet pipe 11. The end of the first outlet pipe 11 away from the cleaning tank 10 is connected to a filter 12. The outlet end of the filter 12 is connected to a second outlet pipe 13. The end of the second outlet pipe 13 away from the filter 12 extends to the top of the interior of the cleaning tank 10.

[0049] A spiral baffle 244 is installed at one end of the upper surface of the spiral ramp 242, and the upper surface of the spiral ramp 242 is provided with anti-slip texture.

[0050] The bolt straightening assembly 24 also includes a plurality of liquid guide tubes 245 passing through the top housing of the vibratory plate 241, and one end of the liquid guide tube 245 extending into the interior of the vibratory plate 241 penetrates the housing of the spiral ascending ramp 242.

[0051] The lower surface of the vibratory feeder 241 is equipped with a plurality of casters 2411, and the vibratory feeder 241 is slidably connected to the inner wall of the cleaning tank 10 through the casters 2411.

[0052] The bottom of the inner part of the material cylinder 332 is provided with a slope;

[0053] It should be noted that in this embodiment, the cleaning liquid in the cleaning tank 10 is guided into the filter 12 for filtration through the first outlet pipe 11. The filtered cleaning liquid enters the second outlet pipe 13 under the action of the pump. Since the second outlet pipe 13 extends to the top of the cleaning tank 10, the cleaning liquid inside the cleaning tank 10 can be recycled.

[0054] Furthermore, the spiral baffle 244 blocks the bolts, reducing the bolts from falling off, and the anti-slip texture increases the friction between the bolts and the spiral rising ramp 242, facilitating the conveying of the bolts within the vibratory feeder 241.

[0055] Furthermore, excess cleaning fluid in the vibratory plate 241 is discharged through the liquid guide pipe 245 to prevent excessive cleaning fluid from increasing the buoyancy of the bolts in the vibratory plate 241 and affecting the bolt conveying.

[0056] Furthermore, the vibratory feeder 241 slides on the inner wall of the cleaning tank 10 via the universal wheels 2411 at its bottom end to reduce the friction between the vibratory feeder 241 and the inner wall of the cleaning tank 10.

[0057] Furthermore, the material cylinder 332 guides the internal bolts to concentrate through its bottom inclined surface, so that the bolts can be concentrated near the discharge ladder 333 to facilitate the discharge of the bolts.

[0058] The specific operation method of this invention is as follows:

[0059] When the bolts are cleaned to facilitate subsequent processing and improve product quality, the rotating disk 23 is rotated by a motor connected to the rotating disk 23. The rotating disk 23 drives the connecting rod 22 to make angular displacement. The connecting rod 22 drives the vibrating disk 241 to pass through the feeding assembly 33, the brushing assembly 32 and the discharging assembly 31 in sequence.

[0060] As the vibratory plate 241 passes sequentially through the feeding assembly 33, the washing assembly 32, and the discharging assembly 31, the support cylinder 331 provides support for the material cylinder 332, the material cylinder 332 collects the bolts, and the discharging ladder 333 guides the bolts inside the material cylinder 332 out. The first hydraulic cylinder 322 drives the lifting frame 323 to rise, so that the lifting frame 323 drives the motor 324 on it to rise and fall. The motor 324 drives the brush head 325 to rotate, and the brush head 325 enters the vibratory plate 241 to clean the bolts inside the vibratory plate 241. The second hydraulic cylinder 312 drives the magnetic separation conveyor belt 313 to rise and fall, so that the magnetic separation conveyor belt 313 extends into the vibratory plate 241 to adsorb and transport the bolts inside the vibratory plate 241, thereby discharging the cleaned bolts.

[0061] As the bolts in the vibratory feeder 241 are cleaned sequentially by the feeding assembly 33, the brushing assembly 32, and the discharge assembly 31, water is supplied to the water outlet pipe 26 through the rotary joint 25. The water outlet pipe 26 sprays water through the spray nozzle 27, causing the fluid to descend along the spiral ascending ramp 242, immersing the bolts on the spiral ascending ramp 242 in the water. During this process, the bolts not only continuously rise through the spiral ascending ramp 242 on the vibratory feeder 241, causing the miscellaneous bolts to be arranged on the spiral ascending ramp 242 for sorting, but also the first ultrasonic vibrator 246 cleans the miscellaneous bolts concentrated at the bottom of the vibratory feeder 241, and the second ultrasonic vibrator 247 cleans the bolts on the spiral ascending ramp 242. At this time, since the spiral ascending ramp 242 is connected to the return rail 243, the bolts are circulated and cleaned within the vibratory feeder 241.

[0062] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
