Description

Technical Field

[0001] The invention belongs to the technical field of steel ball screening, and in particular relates to a device for screening tiny steel ball particles. Background Art

[0002] During the electroplating process, a large number of tiny steel ball particles are added. These particles increase the conductivity of the resistor in the plating solution, thereby achieving uniform and high-quality plating. During the electroplating process, some of the particles will absorb the metal ions produced by the plating process, causing the particles to become irregular. Furthermore, after each bath of electroplating, the particles recovered will be partially worn and contain some substrate debris. The recovered particles need to be screened to select the regular particles for the next electroplating use, otherwise the electroplating conductivity will be affected.

[0003] Conventional screening devices are mainly composed of screening plates. During screening, a receiving box for multiple steel balls of different particle sizes can be set at the bottom of the screening plate. The steel balls are screened through filter screens with different sizes of filter holes by tilting the screening plate. During the entire screening process, only one specification and regular steel ball can be screened at a time, and it is impossible to screen steel balls of different specifications at the same time. The overall screening efficiency is low.

[0004] At the same time, when screening the steel balls, some steel balls with larger diameters and substrate debris will remain above the filter screen. After long-term use, there is a risk of clogging the filter screen, resulting in a decrease in screening efficiency. At this time, the machine must be shut down and manually cleaned, which seriously affects the overall screening efficiency. Summary of the Invention

[0005] The object of the present invention is to provide a tiny steel ball particle screening device to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tiny steel ball particle screening device, comprising a machine base, a material guide plate fixedly installed on the inner cavity of the machine base near the rear end, a first screening part located inside the machine base fixedly installed on the front end of the material guide plate, a second screening part located inside the machine base fixedly installed on the front end of the first screening part, a third screening part located inside the machine base fixedly installed on the front end of the second screening part, an auxiliary screening component fixedly installed on the middle part of the top end of the machine base, mounting slots are provided inside the first screening part, the second screening part and the third screening part, a receiving box is provided directly below the first screening part, the second screening part and the third screening part, the top end of the receiving box is in contact with the bottom end of the machine base, and the bottom end of the receiving box is on the same horizontal plane.

[0007] Before screening the steel ball particles, the receiving box at the bottom corresponds to the first screening part, the second screening part and the third screening part in sequence, and ensures that there is no gap between the two. At the same time, it is necessary to ensure that the bottom ends of the three receiving boxes are on the same plane, and the steel balls for screening are prepared, and the auxiliary screening component is reset to complete the preliminary preparations before screening.

[0008] As a further technical solution of the present invention, an oblique material conveying plate is installed between the first screening part and the second screening part, and between the second screening part and the third screening part.

[0009] As a further technical solution of the present invention, the mounting slots located inside the first screening part, the second screening part and the third screening part are movably connected with the first screen, the second screen and the third screen in sequence, and the first screen, the second screen and the third screen are all located directly above the receiving box.

[0010] As a further technical solution of the present invention, the filter hole diameters inside the first screen, the second screen and the third screen increase successively, a locking frame is fixedly installed at the rear end of the machine base, and a feed tank located directly above the guide plate is fixedly sleeved inside the locking frame.

[0011] Before screening the steel balls, you can select three different specifications of the first screen, the second screen, and the third screen according to the particle size requirements of the steel balls, and ensure that the particle sizes of the first screen, the second screen, and the third screen meet the three different steel ball particle size specifications. Then, install the first screen, the second screen, and the third screen on the installation slots on the first screening part, the second screening part, and the third screening part respectively, and ensure that they are flush with their surfaces. The whole preparation process is completed; When screening steel balls, steel ball particles can be put into the feed tank. At this time, the steel ball particles enter the interior of the guide plate and first enter the interior of the first screening part through the guide of the guide plate, and are filtered and screened through the first screen. After the filtration and screening is completed, the steel ball particles with a particle size larger than the filter hole diameter of the first screen can enter the interior of the second screening part along the feed plate and be filtered and screened through the second screen. The steel ball particles with a particle size larger than the hole diameter of the second screen can enter the interior of the third screening part along the feed plate and be filtered and screened through the third screen. Finally, the steel ball particles that meet the three particle size specifications enter the interior of the receiving box below in turn, completing the simultaneous screening process of particles of different specifications.

[0012] By utilizing the cooperation of the first screening part, the second screening part, the third screening part, the conveying plate and the bottom receiving box, the steel ball particles can roll along the predetermined path after being released, and be filtered through the first screen, the second screen and the third screen along the way, so that three different specifications of steel balls can be screened in relay at the same time. The whole screening process is completed automatically without the need for traditional devices to tilt multiple times and screen in sequence. Steel ball particles of different specifications can be screened at the same time, thereby improving screening efficiency.

[0013] As a further technical solution of the present invention, the auxiliary screening component includes an extended frame, the bottom end of the extended frame is connected to the top of the machine base, a longitudinal electric push rod is fixedly installed in the middle of the inner side of the extended frame, the output end of the longitudinal electric push rod is fixedly installed with a fixed frame, and the inner side of the fixed frame is fixedly installed with a fixed guide rail.

[0014] As a further technical solution of the present invention, the interior of the fixed guide rail is movably connected with a second guide block and a first guide block in sequence. The second guide block is located directly above the second screening part, and the first guide block is located directly above the first screening part. The second guide block and the first guide block are both displaced forward and backward relative to the fixed guide rail.

[0015] As a further technical solution of the present invention, a transverse electric push rod is fixedly installed at the front end of the fixed guide rail inner cavity, the output end of the transverse electric push rod is connected to one side of the second guide block, and a synchronization plate is fixedly connected between the second guide block and the first guide block.

[0016] As a further technical solution of the present invention, guide brushes are fixedly installed on the bottom ends of the first guide block and the second guide block. When the longitudinal electric push rod is in the extreme extension state, the bottom ends of the two guide brushes are in contact with the top of the first screening part and the top of the second screening part respectively. When the transverse electric push rod is in the initial state, the two guide brushes are respectively located on the top of the first screening part and the second screening part close to the side of the material guide plate.

[0017] When a large amount of steel ball particles accumulate on the surface of the first screen and the second screen, and affect normal screening, the longitudinal electric push rod can be turned on to drive the fixed guide rail to move downward. When the fixed guide rail moves downward, the first guide block and the second guide block move downward accordingly, until the guide brush is driven to move downward. When the two guide brushes contact the surfaces of the first screening part and the second screening part respectively, the transverse electric push rod can be turned on to shorten it, and the first guide block and the second guide block can be driven to move toward the front side of the machine base at the same time. At this time, the two guide brushes at the bottom can clean the surfaces of the first screening part and the second screening part respectively, and guide the excess steel ball particles to the next screening position, completing the self-maintenance process.

[0018] By utilizing the coordination between the auxiliary screening component and the first screening part, the second screening part and the third screening part, and utilizing the active action of the auxiliary screening component, the device can automatically perform cleaning and maintenance when blockage occurs, thereby avoiding the problem that traditional devices are prone to blockage and affect screening efficiency after being used for a period of time. The device can automatically perform cleaning regularly during the screening process, effectively improving the screening efficiency and reducing the difficulty of maintenance. It is suitable for use in batch screening of steel ball particles.

[0019] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the cooperation of the first screening part, the second screening part, the third screening part, the feed plate and the bottom receiving box, so that the steel ball particles can roll along a predetermined path after being released, and are filtered by the first screen, the second screen and the third screen along the way, so that three different specifications and regular steel balls can be screened at the same time. The whole screening process is completed automatically, without the need for the traditional device to tilt multiple times and screen in sequence. Steel ball particles of different specifications can be screened at the same time, thereby improving the screening efficiency.

[0020] (2) The present invention utilizes the cooperation between the auxiliary screening component and the first screening part, the second screening part, and the third screening part, and utilizes the active function of the auxiliary screening component to enable the device to automatically perform cleaning and maintenance when blockage occurs, thereby avoiding the problem that traditional devices are prone to blockage and affect screening efficiency after being used for a period of time. The device can automatically perform cleaning regularly during the screening process, effectively improving the screening efficiency and reducing the difficulty of maintenance. It is suitable for use in batch screening of steel ball particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Working principle and usage process: Before screening the steel ball particles, the receiving box 7 at the bottom corresponds to the first screening part 3, the second screening part 4 and the third screening part 5 in sequence, and ensures that there is no gap between them. At the same time, it is necessary to ensure that the bottom ends of the three receiving boxes 7 are on the same plane, and the screened steel balls are prepared, and the auxiliary screening assembly 13 is reset to complete the preliminary preparation before screening; Before screening the steel balls, three different specifications of the first screen 8, the second screen 9, and the third screen 10 can be selected according to the particle size requirements of the steel balls, and the particle sizes of the first screen 8, the second screen 9, and the third screen 10 can be ensured to meet the three different steel ball particle size specifications.

After the filtering and screening is completed, the steel ball particles with a particle size larger than the filter hole diameter of the first screen 8 can follow the material conveying plate to enter the interior of the second screening part 4, and be filtered and screened through the second screen 9. The steel ball particles with a particle size larger than the hole diameter of the second screen 9 can follow the material conveying plate to enter the interior of the third screening part 5, and be filtered and screened through the third screen 10. Finally, the steel ball particles that meet the three particle size specifications enter the interior of the receiving box 7 below in turn, completing the simultaneous screening process of particles of different specifications. When a large amount of steel ball particles accumulate on the surface of the first screen 8 and the second screen 9, and affect normal screening, the longitudinal electric push rod 132 can be turned on to drive the fixed guide rail 134 to move downward. When the fixed guide rail 134 moves downward, the first guide block 135 and the second guide block 136 move downward accordingly, until the guide brush 137 is driven to move downward. When the two guide brushes 137 contact the surfaces of the first screening part 3 and the second screening part 4 respectively, the transverse electric push rod 139 can be turned on to drive it to shorten, and the first guide block 135 and the second guide block 136 can be driven to move toward the front side of the machine base 1 at the same time. At this time, the two guide brushes 137 at the bottom can clean the surfaces of the first screening part 3 and the second screening part 4 respectively, and guide the excess steel ball particles to the next screening position, completing the self-maintenance process.
