Description

Technical Field

[0001] This application relates to the field of fastener processing technology, and in particular to fastener rust prevention treatment devices and methods. Background Technology

[0002] After fasteners such as screws, bolts, and washers are manufactured, their surfaces are usually treated with rust prevention to extend their service life.

[0003] Currently, an oiling mechanism is generally used to apply rust-preventive oil to fasteners to achieve rust prevention. See also Figure 1 The oiling mechanism includes an oil storage tank 1a and a screen barrel 1b. Several through holes are provided at the bottom of the screen barrel 1b. The oil storage tank 1a stores rust-preventive oil. A gantry frame 1c is mounted on the oil storage tank 1a, with its lower end fixed to the ground. An electric hoist 1f is installed on the gantry frame 1c. A connecting rod 1e is horizontally fixed above the screen barrel 1b, and the steel cable of the electric hoist 1f is fixedly connected to the connecting rod 1e. When rust prevention treatment is required for fasteners, the fasteners are first placed in the screen barrel 1b. The electric hoist 1f releases its steel cable to lower the screen barrel 1b into the oil storage tank 1a, immersing the fasteners in the rust-preventive oil. After the required immersion time is met, the electric hoist 1f lifts the screen barrel 1b by rewinding its steel cable, and then the fasteners in the screen barrel 1b are emptied, thus achieving rust prevention treatment for the fasteners.

[0004] In the above technology, the fasteners after rust prevention treatment go directly into the packaging process. During the packaging process, the packaging bag is first placed on a weighing machine, and then a number of fasteners are poured into the packaging bag while the weight measured by the weighing machine is observed to make a preliminary estimate of the number of fasteners contained in the packaging bag. However, during the process of pouring the fasteners into the packaging bag, excess rust-preventive oil enters the packaging bag along with the fasteners, which brings a large error to the weighing data of the packaging bag. Therefore, it needs to be improved. Summary of the Invention

[0005] This application provides a fastener rust prevention treatment device and treatment method, which helps to reduce the impact of the weight of the rust-preventive oil on the fastener weighing data.

[0006] The first objective of this invention is achieved through the following technical solution:

[0009] Optionally, the oil screening assembly comprises a mounting frame, a screening bed and a screening moving structure, the two sides of the screening bed are respectively provided with a plurality of connecting pieces, the screening bed is movably arranged on the mounting frame through the connecting pieces, the upper surface of the screening bed is arranged in an open manner, and the bottom of the inner side of the screening bed is arranged in an inclined downward manner from the inlet side to the outlet side; one side of the screening bed is an inlet side, the other side of the screening bed is an outlet side, the bottom of the screening bed is provided with an oil outlet structure, and the screening moving structure is arranged on the inlet side of the screening bed and connected with the screening bed and used for driving the screening bed to move.

[0010] By adopting the above technical scheme, the fastener enters the sieve bed from the feeding side, the sieve moving structure drives the sieve bed to move, the sieve bed moves on the mounting frame through the connecting piece, the sieve bed drives the fastener to move, and the sieve bed screens out the excess rust-proof oil on the surface of the fastener through the oil screening structure, thereby realizing the function of automatically screening out the rust-proof oil. Moreover, the inner bottom of the sieve bed is inclined downward from the feeding side to the discharging side, so that the fastener slides from the feeding side to the discharging side during the movement of the sieve bed, and the fastener is more easily moved to the discharging side to realize discharging.

[0011] Optionally, the connecting piece comprises a supporting shaft and a hanging arm, one end of the supporting shaft is mounted on the side wall of the sieve bed, the other end of the supporting shaft is rotationally connected with one end of the hanging arm, the other end of the hanging arm is rotationally connected with the mounting frame, and the bottom of the sieve bed is higher than the ground.

[0012] By adopting the above technical scheme, the sieve moving structure is provided with the supporting shaft and the hanging arm, on the one hand, the bottom of the sieve bed is higher than the ground, so as to further reduce the friction during the movement of the sieve bed and make the movement of the sieve bed more smooth, and on the other hand, the one end of the hanging arm is rotationally connected with the mounting frame, and the other end of the hanging arm is rotationally connected with the supporting shaft, so that the hanging arm is beneficial to the stability of the movement of the sieve bed relative to the mounting frame.

[0014] By adopting the above technical scheme, the motor drives the connecting shaft to rotate through a pair of belt pulleys, the connecting shaft drives the eccentric wheel to rotate, the eccentric wheel drives the traction part to move, and the traction part drives the sieve bed to shake. Since the inner bottom of the sieve bed is inclined from the feeding side to the discharging side, and the traction part is located at the feeding side of the sieve bed, the power source provided by the sieve moving structure for the sieve bed is derived from the feeding side of the sieve bed, so that the direction of the shaking of the sieve bed is the same as the inclination direction of the inner bottom of the sieve bed. Therefore, on the basis of the sieve moving function of the sieve bed for realizing the oil screening function, the discharging efficiency of the fastener is further improved.

[0015] Optionally, the traction part comprises a mounting rod and a connecting rod, the mounting rod is fixedly mounted on the outer side wall of the feeding side of the sieve bed, the connecting rod is rotationally connected with the mounting rod, one side of the eccentric wheel away from the belt pulley is provided with an eccentric shaft, and the connecting rod is rotationally connected with the eccentric shaft.

[0017] Preferably, the loading box is fixedly provided with a rotating shaft, two ends of the rotating shaft penetrating through opposite two side walls of the loading box, the driving assembly comprises a rack and a driving member, the rack is arranged on one side of the oil storage pool, the driving member is arranged on the rack, one end of the rotating shaft is provided with a connecting block, the driving member drives the rotating shaft to move towards or away from the inside of the oil storage pool through the connecting block, the rack is provided with a turnover station, the turnover station is located above the oil storage pool, and the driving assembly further comprises a rotating structure, the rotating structure is used for driving the rotating shaft to rotate into the turnover station.

[0018] By adopting the above scheme, since the rotating shaft penetrates through the side wall of the loading box, when the driving member drives the rotating shaft to move towards or away from the inside of the oil storage pool through the connecting block, the loading box can move synchronously with the rotating shaft, so that the loading box can move stably, and it is not necessary to arrange the driving assembly on both sides of the loading box; and the rotating structure can drive the rotating shaft to rotate, since the rotating shaft is fixedly connected with the loading box, the rotating shaft drives the loading box to overturn when the rotating shaft rotates, so that the loading box is overturned to discharge materials.

[0019] Preferably, the rotating structure comprises a first rack and a gear, one end of the first rack is arranged on one side of the rack and located in the turnover station, and the length direction of the first rack is parallel to the moving direction of the loading box, the gear is fixedly arranged coaxially on the rotating shaft, and the first rack is used for guiding the gear to rotate to overturn the loading box.

[0020] By adopting the above scheme, during the process that the driving member drives the loading box into the turnover station, the gear is engaged with the first rack, the first rack guides the gear to rotate, the gear drives the rotating shaft to rotate, the loading box is overturned with the rotating shaft, and the function of automatically overturning and discharging materials of the loading box is realized.

[0022] By adopting the technical scheme, when the driving member drives the charging box to enter the inside of the oil storage pool, the second rack adjusts the direction of the charging box, so that the charging box keeps a vertical state and the bottom of the charging box faces the inside of the oil storage pool, and the charging box is more accurately aligned and enters the inside of the oil storage pool.

[0023] The second application purpose of the application is achieved by the following technical scheme.

[0024] The fastener rust-proof treatment method is implemented by the fastener rust-proof treatment device, and the method comprises the following steps:

[0025] Obtaining current position information of the charging box;

[0026] Based on the current position information, it is judged whether the charging box is located at an initial position, and the initial position is that the bottom of the charging box enters the inside of the oil storage pool and is located above the rust-proof oil surface of the oil storage pool;

[0027] When it is determined that the charging box is located at the initial position, first bearing information in the charging box is obtained;

[0028] When the first bearing information is lower than a first preset bearing threshold, feeding reminding information is generated;

[0029] When the first bearing information meets the first preset bearing threshold, rust-proof treatment execution information is generated;

[0030] The rust-proof treatment execution information is sent to the driving assembly and the oil immersion timing is started;

[0031] When the timing duration reaches a preset time threshold, oil screening execution signals are generated; the oil screening execution signals comprise oil draining sub-signals and oil screening sub-signals;

[0032] The oil screening execution signals are sent to the oil screening assembly.

[0033] Before the rust-proof treatment, it is necessary to confirm whether the loading box is in the initial position, so that the worker can judge whether it can be directly fed. When the bottom of the loading box enters the rust-proof oil, if it is directly fed at this time, it is easy to splash the rust-proof oil. Therefore, the bottom of the loading box is located in the oil storage pool and above the rust-proof oil surface of the oil storage pool as the initial position, which can facilitate the worker to pour a batch of fasteners into the loading box, and at the same time, avoid the splashing of rust-proof oil when pouring. On this basis, the first bearing information in the loading box is obtained to judge whether the fasteners are loaded in the current loading box. When the first bearing information is equal to the first preset bearing threshold, the rust-proof treatment execution information is sent to the driving assembly, and the driving assembly drives the loading box to act, thereby starting the rust-proof treatment, and at the same time, starting the timing, so as to accurately obtain the time length of the fasteners for rust-proof treatment, so as to avoid that the rust-proof time is too long or too short to affect the rust-proof treatment effect; When the timing time length reaches the preset time threshold, the oil screening execution information is sent to the oil screening assembly, and the oil screening assembly screens the fasteners after the rust-proof treatment at this time, thereby separating the excess rust-proof oil from the fasteners, thereby reducing the excess rust-proof oil on the surface of the fasteners, thereby helping to reduce the influence of the weight of the rust-proof oil on the weighing data of the fasteners.

[0034] Preferably, the step of sending the oil screening execution signal to the oil screening assembly comprises:

[0035] The oil screening sub-signal is sent to the oil screening assembly to start the oil screening assembly;

[0036] The oil draining sub-signal is sent to the driving assembly, and oil draining timing is started;

[0037] When the oil draining timing reaches the preset oil draining time length, the oil draining discharge information is generated;

[0038] The oil draining discharge information is sent to the driving assembly;

[0039] Based on the oil draining discharge information, the second bearing information of the loading box is obtained in real time;

[0040] When the second bearing information is lower than the second preset bearing threshold, the reset information associated with the loading box is generated;

[0041] The reset information is sent to the driving assembly.

[0042] When the anti-rust treatment process is completed, the oil screening signal is sent to the oil screening assembly, so that the oil screening assembly works to make the oil screening action before the fastener to be screened enters the oil screening assembly, and the oil draining information is sent to the driving assembly, at this time the driving assembly acts and makes the charging box separate from the anti-rust oil of the oil storage pool and makes the charging box stand above the oil storage pool. Since the charging box has a oil permeable hole at the bottom, the excess anti-rust oil in the charging box can drip into the oil storage pool through the oil permeable hole at this time, thereby realizing the oil draining operation. When the oil draining is completed, the oil draining discharge information is sent to the driving assembly, and the driving assembly drives the charging box to overturn to realize the pouring of the fastener after oil draining into the oil screening assembly, and the oil screening assembly can immediately screen the fastener, further improving the oil screening efficiency.

[0043] In summary, the beneficial technical effects of the present application are:

[0044] 1. The charging box is movably installed in the oil storage pool by the driving assembly. When the fastener to be treated is placed in the charging box, the driving assembly drives the charging box to move downward until the anti-rust oil in the oil storage pool enters the charging box through the oil permeable hole, thereby making the fastener in the charging box soak in the anti-rust oil. When the soaking is completed, the driving assembly drives the charging box to rise to leave the oil storage pool. Since there is still a lot of anti-rust oil in the charging box at this time, the driving assembly drives the charging box to rise to a certain height and stops driving the charging box to continue rising. In this process, the excess anti-rust oil in the charging box drips into the oil storage pool through the oil permeable hole. When the standing is completed, the oil storage pool is arranged on the feeding side of the oil screening assembly. Next, the controller controls the driving assembly to drive the charging box to overturn to make the discharge port of the charging box communicate with the feeding port of the oil screening assembly. At this time, the fastener in the charging box falls into the oil screening assembly, and the controller controls the oil screening assembly to screen the fastener, thereby separating the excess anti-rust oil from the fastener, thereby reducing the excess anti-rust oil on the surface of the fastener, thereby helping to reduce the influence of the weight of the anti-rust oil on the weighing data of the fastener.

[0045] 2. Before the rust-proof treatment, it is necessary to confirm whether the loading box is in the initial position, so that the worker can judge whether it can be directly fed. When the bottom of the loading box enters the rust-proof oil, if it is directly fed at this time, it is easy to splash the rust-proof oil. Therefore, the initial position is that the bottom of the loading box is located in the oil storage pool and above the rust-proof oil surface of the oil storage pool, which can facilitate the worker to pour a batch of fasteners into the loading box, and at the same time, avoid the splashing of rust-proof oil when pouring. On this basis, the first bearing information in the loading box is obtained to judge whether the fasteners are loaded in the current loading box. When the first bearing information is equal to the first preset bearing threshold, the rust-proof treatment execution information is sent to the driving assembly, the driving assembly drives the loading box to act, and the rust-proof treatment starts. At the same time, the timing starts to accurately obtain the time length of the fasteners for rust-proof treatment, so as to avoid that the rust-proof time is too long or too short to affect the rust-proof treatment effect; when the timing length reaches the preset time threshold, the oil screening execution information is sent to the oil screening assembly, and the oil screening assembly screens the fasteners after the rust-proof treatment at this time, so as to separate the excess rust-proof oil from the fasteners, thereby reducing the excess rust-proof oil on the surface of the fasteners, and thereby helping to reduce the influence of the weight of the rust-proof oil on the weighing data of the fasteners.

[0059] The following Figures 2-10 The application is further described in detail.

[0060] In the rust-proof treatment process of fasteners, the fasteners can be completed rust-proof treatment after being soaked in rust-proof oil for a period of time. However, in actual processing, there is often excess rust-proof oil on the surface of the fasteners, and when the batch of fasteners containing rust-proof oil are packed, the excessive oil content of the fasteners has a certain influence on the judgment of the net content of the fasteners in the packing bag. Therefore, the fastener rust-proof treatment device provided in the embodiments of the application is applied to the rust-proof treatment processing procedure of screws, gaskets and other fasteners, and is beneficial to solve the problem that the excess rust-proof oil in the related art affects the accuracy of the weight of the packed fasteners.

[0061] Reference Figure 2The rust-proof treatment device comprises an oil storage tank 1 and a loading box 2. The oil storage tank 1 is used for storing rust-proof oil. The loading box 2 is provided with an opening on the top, which is used for the fastener to enter or exit the loading box 2. The lower part of the loading box 2 is provided with a plurality of oil holes 21, the size of the oil holes 21 is smaller than the minimum size of the fastener, so that the oil holes 21 are only used for rust-proof oil to pass through. One side of the oil storage tank 1 is provided with a driving assembly for driving the loading box 2 to move up and down and overturn, and the loading box 2 is movably installed on the oil storage tank 1 through the driving assembly. The treatment device further comprises a oil screening assembly 3, one side of the oil screening assembly 3 is an inlet side, and the other side of the oil screening assembly 3 is an outlet side. The oil storage tank 1 is located on the inlet side of the oil screening assembly 3. When the loading box 2 is in an overturned state, the opening of the loading box 2 is communicated with the inlet of the oil screening assembly 3, and the outlet side of the oil screening assembly 3 is provided with a containing assembly. Therefore, the cooperation of the driving assembly, the oil storage tank 1 and the loading box 2 realizes the rust-proof treatment and oil draining treatment of the fastener. The cooperation of the loading box 2, the driving assembly and the oil screening assembly 3 helps to screen out the excess rust-proof oil on the fastener, thereby reducing the excess rust-proof oil on the surface of the fastener, and thereby helping to reduce the influence of the weight of the rust-proof oil on the weighing data of the fastener.

[0062] The treatment device further comprises a controller, the driving assembly is connected with the controller, so that the controller controls the start and stop of the driving assembly. The oil screening assembly 3 is connected with the controller, so as to control the start and stop of the oil screening assembly 3.

[0063] Since the fastener needs to be subjected to rust-proof treatment before being subjected to oil screening treatment, in the embodiment, the rust-proof treatment part and the oil screening treatment part are described according to the processing sequence of the fastener.

[0064] Referring to Figure 3 and Figure 4 , the driving assembly comprises a rack 61 and a driving piece 62. The rack 61 is arranged on one side of the oil storage tank 1, and the driving piece 62 is installed on the top of the rack 61. In the embodiment, the driving piece 62 is a telescopic cylinder, and the piston rod of the telescopic cylinder faces downward. The loading box 2 is fixedly installed with a rotating shaft 22. The rotating shaft 22 is transversely arranged on the loading box 2, and the two ends of the rotating shaft 22 penetrate through the opposite two side walls of the loading box 2. The end of the rotating shaft 22 close to the rack 61 penetrates out of the loading box 2 and is fixedly installed with a connecting block 221. The piston rod of the telescopic cylinder is fixedly connected with the top of the connecting block 221, so as to realize the driving of the rotating shaft 22 to move up and down through the connecting block 221, so that the loading box 2 can move towards or away from the inside of the oil storage tank 1, thereby realizing the movable installation of the loading box 2 on the oil storage tank 1.

[0065] In order to further improve the stability of the movement of the charging box 2, the anti-rust treatment equipment comprises a guide for guiding the movement of the connecting block 221 and the charging box 2 more stably. The guide comprises a guide column 81 and a sliding sleeve 82. The upper end and the lower end of the guide column 81 are both mounted to the rack 61, and the length direction of the guide column 81 is consistent with the movement direction of the charging box 2. The sliding sleeve 82 is fixedly connected to the side wall of the connecting block 221 away from the gear 72, and the sliding sleeve 82 is in sliding fit with the guide column 81 to guide the lifting of the connecting block 221, thereby making the lifting of the charging box 2 more stable.

[0066] It should be noted that when the charging box 2 is in an idle state, the charging box 2 is in an initial position, which means that the bottom of the charging box 2 enters the oil storage pool 1 and is located above the anti-rust oil level of the oil storage pool 1. Before the fasteners are subjected to anti-rust treatment, the charging box 2 needs to be placed in the initial position, and then the charging box 2 in the initial position is filled with the fasteners to avoid the splashing of the anti-rust oil during the filling of the fasteners.

[0067] After the fasteners are filled into the charging box 2, the controller controls the driving member 62 to drive the charging box 2 to descend, and the anti-rust oil in the oil storage pool 1 penetrates into the charging box 2 through the oil penetration holes 21 and immerses the fasteners in the charging box 2, at this time, the anti-rust oil adheres to the surface of the fasteners, thereby realizing the anti-rust treatment.

[0068] During the anti-rust treatment process, a large amount of anti-rust oil penetrates into the charging box 2 through the oil penetration holes 21, and thus after the anti-rust treatment is completed, the telescopic cylinder drives the charging box 2 to ascend until the bottom of the charging box 2 is higher than the anti-rust oil level, at this time, the controller controls the telescopic cylinder to stop, at this time, the charging box 2 is stationary at the current position, and a large amount of anti-rust oil in the charging box 2 drips into the oil storage pool 1 through the oil penetration holes 21, thereby realizing the oil draining operation.

[0069] After the oil draining is completed, the fasteners in the charging box 2 need to be poured into the oil screening assembly 3 for oil screening treatment. Specifically, the rack 61 is provided with a turnover station located above the oil storage pool 1. The driving assembly further comprises a rotating structure for guiding the turnover of the charging box 2. After the oil draining operation is completed, the controller controls the cylinder to continue driving the charging box 2 to ascend and enter the turnover station under the guidance of the rotating structure. The rotating assembly guides the turnover of the charging box 2, and the fasteners are poured out of the charging box 2 and into the oil screening assembly 3, thereby making the fasteners enter the oil screening process from the oil draining process.

[0070] Referring to Figure 3 and Figure 5The rotating structure includes a first rack 71 and a gear 72. One end of the first rack 71 is fixedly mounted on one side of the frame 61 and located at the flipping station. The length direction of the first rack 71 is parallel to the moving direction of the loading box 2. In this embodiment, the length direction of the first rack 71 is consistent with the vertical direction. The gear 72 is fixedly coaxially mounted on the rotating shaft 22 and is located between the outer wall of the loading box 2 and the connecting block 221. The gear 72 is used to mesh with the first rack 71 so that the first rack 71 can guide the gear 72 to rotate, thereby flipping the loading box 2 into the flipping station.

[0071] Figure 3 The diagram shows the state of the loading box 2 preparing to enter the tilting station. When the loading box 2 is below the tilting station and needs to enter, the controller controls the cylinder to drive the loading box 2 to rise, moving towards the tilting station. When the loading box 2 rises to a certain height, the first rack 71 and the gear 72 begin to mesh. Since the first rack 71 is fixed to the frame 61, it guides the gear 72 to rotate in the forward direction. The gear 72 drives the rotating shaft 22 to rotate, which in turn drives the loading box 2 to tilt, allowing it to enter the tilting station. At this time, the loading box 2 is in a tilted state, realizing the function of the fasteners inside the loading box 2 entering the oil screening assembly 3. When the loading box 2 needs to leave the tilting station, the controller controls the cylinder to drive the loading box 2 to descend. During this process, the first rack 71 guides the gear 72 to rotate in the reverse direction, and the gear 72 drives the loading box 2 to tilt in the reverse direction, changing the loading box 2 from the tilted state to the vertical state and leaving the tilting station.

[0072] like Figure 6 As shown, the rotation angle of the first rack 71 and the guide gear 72 is set as α. α is formed by the combination of auxiliary lines L1 and L2 in the figure. The range of α is 0°-120°, thereby realizing the function of flipping the loading box 2 and emptying the fasteners.

[0073] After the fasteners enter the oil screening assembly 3, the loading box 2 needs to return to its initial position. To facilitate a smoother return of the loading box 2 to the oil storage tank 1, please refer to [reference needed]. Figure 6 The rotating structure includes a connecting part 73 and a second rack 74. One end of the connecting part 73 is fixedly connected to the end of the first rack 71 away from the frame 61, and the other end of the connecting part 73 is fixedly connected to one end of the second rack 74. The other end of the second rack 74 is fixedly connected to the bottom of the frame 61 and located on one side of the oil storage tank 1. The length directions of both the connecting part 73 and the second rack 74 are vertical to ensure that the loading box 2 always moves towards or away from the oil storage tank 1. The connecting part 73 is configured to cooperate with the frame 61 to improve the stability of the engagement between the gear 72 and the first rack 71 and the second rack 74.

[0074] The controller controls the cylinder to drive the charging box 2 to descend. When the bottom of the charging box 2 enters the inside of the oil storage pool 1, the second rack 74 engages with the gear 72 and guides the gear 72 to rotate by a certain angle. The rotating shaft 22 drives the charging box 2 to overturn by a certain angle, so as to adjust the direction of the charging box 2 and make the charging box 2 align with the oil storage pool 1, thereby facilitating the charging box 2 to enter the inside of the oil storage pool 1. In the embodiment, the length of the second rack 74 is less than the length of the first rack 71, and the second rack 74 guides the gear 72 to rotate by an angle range of 0°-5°, so that the bottom of the charging box 2 can be adjusted to face any direction, without the need to realize large-amplitude overturning of the charging box 2. At the same time, when the charging box 2 is in the initial position, the cylinder stops working, and at this time, the second rack 74 engages with the gear 72, so that the charging box 2 can be stably kept in the initial position.

[0075] For the convenience of understanding, the side of the charging box 2 close to the oil screening assembly 3 is set as the discharging side, and the side of the charging box 2 is set as the feeding side. The worker pours the fasteners to be treated for rust prevention into the charging box 2 from the feeding side of the charging box 2. When the charging box 2 overturns to discharge, the fasteners fall from the discharging side of the charging box 2 to the oil screening assembly 3. In order to facilitate the charging box 2 to discharge the fasteners, a guide part is installed at the opening of the charging box 2, see Figure 3 and Figure 4 The guide part includes two enclosing plates 23 and a guide plate 24. The guide plate 24 is installed on the outer side wall of the charging box 2 at the discharging side, and is used to guide the fasteners poured out of the charging box 2. The two enclosing plates 23 are respectively installed on the two sides of the guide plate 24, and the enclosing plates 23 make the poured fasteners more gathered on the guide plate 24. The two enclosing plates 23 and the guide plate 24 enclose to form a discharging opening. The charging box 2 is filled with fasteners from the feeding side, and the fasteners are guided to fall out of the discharging opening through the guide plate 24 when discharging. The enclosing plates 23 make the fasteners being discharged more gathered at the discharging opening, thereby further improving the accuracy of the discharging operation.

[0076] The outer side wall of the charging box 2 at the feeding side is fixedly provided with a blocking plate 25. In the process of pouring the fasteners into the charging box 2, the fasteners can be more accurately poured into the charging box 2 under the limiting action of the blocking plate 25, so that the efficiency of discharging is higher.

[0077] Looking back at Figure 3 In the embodiment, an avoiding groove is provided on the opening side of the oil storage pool 1. The avoiding groove is used to avoid the cooperation with the rotating shaft 22. When the charging box 2 enters the inside of the oil storage pool 1, the avoiding groove is used to provide a placing space for the rotating shaft 22, so that the oil passing hole of the charging box 2 is closer to the bottom of the oil storage pool 1, thereby making more rust-proof oil penetrate into the charging box 2, and improving the availability of the rust-proof oil in the oil storage pool 1.

[0078] The fasteners in the charging box 2 still have a large amount of rust-proof oil on the surface after the oil draining operation, and therefore need to be screened at the oil screening assembly 3, wherein the oil screening assembly 3 comprises a mounting frame 31, a screening bed 32 and a screening moving structure 4. The screening bed 32 is movably mounted on the mounting frame 31 through a plurality of connecting pieces arranged on both sides of the screening bed 32. The bottom of the screening bed 32 is provided with an oil outlet structure for flowing the rust-proof oil on the screening bed 32 out, which in this embodiment is composed of a plurality of oil outlet holes. The screening moving structure 4 is connected with a controller and the screening bed 32, and the controller can drive the screening bed 32 to shake horizontally by controlling the screening moving structure 4, thereby screening the excess rust-proof oil on the surface of the fasteners.

[0079] In order to more accurately pour the fasteners from the feeding side into the screening bed 32, the top end of the side wall of the screening bed 32 at the feeding side is provided with a feeding piece for guiding the fasteners into the screening bed 32, referring to Figure 3 , the feeding piece comprises a guide plate 321 and two baffles 322. The guide plate 321 is mounted on the top end of the side wall of the screening bed 32 at the feeding side, and is arranged obliquely downward from the side away from the screening bed 32 to the screening bed 32, facilitating the sliding of the fasteners into the screening bed 32. One side of each of the two baffles 322 is fixedly connected with one side of the guide plate 321, and the two baffles 322 gather the fasteners on the guide plate 321. The two baffles 322 and the guide plate 321 form a feeding port, which is in communication with the opening of the upper surface of the screening bed 32, facilitating the more accurate entry of the fasteners into the screening bed 32.

[0080] It should be noted that the screening bed 32 has a certain length, one side of the screening bed 32 is the feeding side, and the other side of the screening bed 32 is the discharging side. The upper surface of the screening bed 32 is arranged in an open manner. The bottom of the inner side of the screening bed 32 is arranged obliquely downward from the feeding side of the screening bed 32 to the discharging side of the screening bed 32. The screening moving structure 4 is mounted on the feeding side of the screening bed 32, so that when the screening moving structure 4 drives the screening bed 32 to shake horizontally, the shaking direction of the screening bed 32 is basically the same as the oblique direction of the inner bottom of the screening bed 32. This arrangement on the one hand promotes the shaking of the fasteners on the screening bed 32, thereby further improving the oil screening efficiency, and on the other hand facilitates the movement of the fasteners from the feeding side of the screening bed 32 to the discharging side, thereby improving the discharging efficiency.

[0081] In order to improve the stability of the connection between the screening bed 32 and the mounting frame 31, the number of connecting pieces is arranged in several groups, and the several groups of connecting pieces are equally distributed on both sides of the screening bed 32. Referring to Figure 7 and Figure 8The connecting piece comprises a supporting shaft 51 and a hanging arm 52. The supporting shaft 51 is horizontally arranged and fixedly installed at one end of the outer side wall of the sieve bed 32. The supporting shaft 51 is sleeved with a bearing. The two ends of the connecting arm are provided with mounting holes. The supporting shaft 51 is rotationally connected with the mounting hole at one end of the connecting arm through the bearing. The other end of the supporting shaft 51 is rotationally connected with one end of the hanging arm 52. The other end of the hanging arm 52 is rotationally connected with the mounting frame 31. The mounting frame 31 is provided with a mounting shaft for mounting the connecting arm on the side wall facing the sieve bed 32. The end of the mounting shaft away from the supporting rod is provided with an external thread. The mounting shaft is sleeved with a bearing. The mounting shaft is rotationally connected with the mounting hole at the end of the connecting arm away from the supporting shaft 51 through the bearing, so as to rotationally connect the connecting arm with the supporting rod and the sieve bed 32 respectively. When the sieve bed 32 is installed on the mounting frame 31, the bottom of the sieve bed 32 is higher than the ground, thereby reducing the friction received by the sieve bed 32 during horizontal shaking.

[0082] Referring to Figure 8 and Figure 9 , the sieve moving structure 4 comprises a motor 41, a connecting shaft 42, an eccentric wheel 43 and a traction part 44. The motor 41 is installed on one side of the mounting frame 31. The connecting shaft 42 is rotationally installed on the mounting frame 31 and transversely arranged on the feeding side of the sieve bed 32. The motor 41 drives the connecting shaft 42 to rotate through a pair of belt pulleys. The end of the connecting shaft 42 away from the belt pulley is fixedly connected with the central shaft of the eccentric wheel 43. The connecting shaft 42 is fixedly connected with the central shaft of the eccentric wheel 43, so that the connecting shaft 42 can drive the eccentric wheel 43 to rotate. Under the cooperation of the eccentric wheel 43 and the traction part 44, the connecting shaft 42 drives the sieve bed 32 to horizontally shake through the traction part 44.

[0083] Specifically, the eccentric wheel 43 further comprises an eccentric shaft located on the side of the eccentric wheel 43 away from the belt pulley. The sieve moving structure 4 comprises the traction part 44. The sieve moving structure 4 drives the sieve bed 32 to move through the traction part 44. Specifically, the traction part 44 comprises a mounting rod 441 and a connecting rod 442. The two ends of the connecting rod 442 are respectively provided with sleeve holes. The mounting rod 441 is transversely installed on the outer side wall of the feeding side of the sieve bed 32. The sleeve hole at one end of the connecting rod 442 is sleeved on the mounting rod 441. The connecting rod 442 is rotationally connected with the mounting rod 441 through the sleeve hole. The eccentric shaft of the eccentric wheel 43 is rotationally connected with the sleeve hole at the other end of the connecting rod 442. The motor 41 drives the connecting shaft 42 to rotate through a pair of belt pulleys. The connecting shaft 42 drives the eccentric wheel 43 to rotate. The eccentric wheel 43 can drive the connecting rod 442 to reciprocate to realize the function of driving the sieve bed 32 to horizontally shake. The combined structure of the eccentric wheel 43 and the connecting rod 442 is simple, so that the maintenance cost of the sieve moving structure 4 is lower.

[0084] In order to collect the rust-proof oil screened out by the sieve bed 32 and reuse it, the sieve oil assembly 3 is provided with a guide oil piece for collecting the rust-proof oil screened out by the sieve bed 32. Referring to Figure 3 andFigure 7 The oil guide includes an oil guide plate 91 and two side plates 92, the upper sides of the two side plates 92 are fixedly connected with the two outer sidewalls of the sieve bed 32 respectively, the lower sides of the two side plates 92 are fixedly connected with the two sides of the oil guide plate 91 respectively, the oil guide plate 91 and the two side plates 92 enclose an oil loading cavity 93, the oil loading cavity 93 is located below the oil outlet holes and communicates with the oil outlet holes, and the oil loading cavity 93 is used for receiving the rust-proof oil flowing out of the oil outlet holes. The oil guide plate 91 is arranged obliquely from the feeding side to the discharging side, so that the rust-proof oil can be guided to the discharging side. The two side plates 92 and the oil guide plate 91 enclose an oil outlet at the discharging side of the sieve bed 32, the oil outlet communicates with the oil loading cavity 93, and an oil tank 112 is arranged below the oil outlet, so that the rust-proof oil can be collected.

[0085] In order to collect the fasteners at the discharging side of the sieve bed 32, a discharging element is arranged at the discharging side of the sieve bed 32, referring to Figure 3 The discharging element includes a discharging plate 101 and two inclined plates 102, the discharging side of the sieve bed 32 is arranged in an open manner, the discharging plate 101 is fixedly connected with the outer bottom side of the discharging side of the sieve bed 32, one side of each of the two inclined plates 102 is fixedly connected with the two sides of the discharging plate 101, and the two inclined plates 102 and the discharging plate 101 enclose a discharging opening, the discharging opening communicates with the opening of the discharging side of the sieve bed 32, and the sieve bed 32 is conveniently discharged. The receiving assembly is located below the discharging opening, and in this embodiment, the receiving assembly is a collection box 111, which is used for collecting the fasteners after oil screening, so that the subsequent packaging of batches of fasteners can be facilitated.

[0086] As a further optimization of the oil screening function of the sieve bed 32, the oil screening assembly 3 includes a deoiling structure, referring to Figure 3 The deoiling structure includes a fan 121, an air pipe 122, an air cover 123 and a supporting lever 124, and the fan 121 is arranged on the ground. The supporting lever 124 is horizontally arranged above the sieve bed 32 and is fixedly connected with the sieve bed 32, one side of the air cover 123 is fixedly connected with the supporting lever 124 by bolts, and the air outlet of the air cover 123 faces the inside of the sieve bed 32. One end of the air pipe 122 is connected with and communicates with the fan 121, and the other end of the air pipe 122 communicates with the inside of the air cover 123. The air pipe 122 communicates with the inside of the air cover 123, the air pipe 122 guides the air of the fan 121 to the inside of the air cover 123, and the air cover 123 blows the air to the sieve bed 32, so that the rust-proof oil on the sieve bed 32 can enter more quickly. In this embodiment, the air cover 123 is arranged in a strip shape and has a length equal to the width of the sieve bed 32, so that the air cover 123 can sufficiently blow the excess rust-proof oil on the surface of the fasteners to the oil outlet holes.

[0087] In this embodiment, the deoiling structure is provided with two groups, and the two groups of deoiling structures share one fan 121 for blowing.

[0088] The working principle of the embodiment of the application is:

[0089] When the loading box 2 is filled with fasteners to be treated, the cylinder drives the loading box 2 to move downward until the rust-proof oil in the oil pool 1 enters the loading box 2 through the oil hole 21, so that the fasteners in the loading box 2 are soaked in the rust-proof oil for a period of time to achieve rust-proof treatment.

[0090] When the soaking is completed, the cylinder drives the loading box 2 to rise to leave the oil pool 1, and since there is still a lot of rust-proof oil in the loading box 2 at this time, the cylinder drives the loading box 2 to stop rising after rising to a certain height, and at this time, the loading box 2 is in the oil draining process, and in this oil draining process, the excess rust-proof oil in the loading box 2 drips into the oil pool 1 through the oil hole 21.

[0091] When the oil draining is completed, the controller controls the driving assembly to drive the loading box 2 to overturn so that the discharge port of the loading box 2 is communicated with the feeding port of the oil screening assembly 3, and at this time, the fasteners in the loading box 2 fall into the oil screening assembly 3, and the controller controls the oil screening assembly 3 to perform oil screening operation on the fasteners, so that the excess rust-proof oil is separated from the fasteners, thereby reducing the excess rust-proof oil on the surface of the fasteners, thereby helping to reduce the influence of the weight of the rust-proof oil on the weighing data of the fasteners.

[0092] The embodiment of the application also discloses a fastener rust-proof treatment method, which is implemented based on the fastener rust-proof treatment device in the above embodiment. The following method is executed by the controller in the rust-proof treatment device.

[0093] Referring to Figure 10 , the method comprises:

[0094] S1, obtaining current position information of the loading box 2.

[0095] Since the loading box 2 needs to be adjusted to the initial position before rust-proof treatment, the staff can pour a batch of fasteners into the loading box 2, and the rust-proof oil splashing during pouring can be avoided.

[0096] S2, judging whether the loading box 2 is located at the initial position based on the current position information, the initial position being that the bottom of the loading box 2 enters the oil pool 1 and is located above the rust-proof oil surface of the oil pool 1.

[0097] In the embodiment, the side wall of the rack 61 is provided with an infrared emitter, and the side wall of the connecting block 221 is provided with an infrared receiver for receiving the infrared emitted by the infrared emitter, and the infrared receiver is connected with the controller. When the charging box 2 is in the initial position, the infrared receiver of the connecting block 221 receives the light emitted by the infrared emitter of the oil storage tank 1, and sends a to-position signal to the controller, and the controller responds to the to-position signal and determines that the charging box 2 is currently in the initial position. When the charging box 2 is in a non-initial position, the infrared receiver of the connecting block 221 does not receive the light emitted by the infrared emitter of the oil storage tank 1, and at this time the infrared receiver sends a non-to-position signal to the controller, and the controller responds to the non-to-position signal and determines that the charging box 2 is not in the initial position at this time, and returns to step S1 at this time.

[0098] It should be noted that when the controller continuously receives the to-position signal, for example, within a period of time (such as 5S), the to-position signal is received, it is determined that the charging box 2 is in the initial state at this time, and such setting is beneficial to improve the accuracy of determining that the charging box 2 is in the initial position.

[0099] S3, when it is determined that the charging box 2 is in the initial position, the first load information in the charging box 2 is obtained.

[0100] The first pressure sensor is installed in the charging box 2, and the first pressure sensor is connected with the controller. The first pressure sensor is used to obtain the first load information, and the first pressure sensor can send the first load information to the controller.

[0101] S3-1, when the first load information is lower than the first preset load threshold, a feeding reminder information is generated.

[0102] The first preset load threshold can be pre-set according to the actual processing condition.

[0103] For example, the first preset load threshold is 30kg, and the first load information is 0kg, so the first load information is lower than the first preset load threshold, and the feeding reminder information is generated.

[0104] The side wall of the rack 61 is provided with a warning light group, and the warning light group is connected with the controller. The warning light group includes a red light and a green light, and when the anti-rust treatment device is started and the first load information is lower than the first preset load threshold, the controller controls the green light of the warning light group to light up, thereby reminding the staff to feed.

[0105] S3-2, when the first load information meets the first preset load threshold, an anti-rust treatment execution information is generated.

[0106] For example, the first preset bearing threshold is 30-35 kg, and the first bearing information is 30 kg. Therefore, the first bearing information meets the range of the first preset bearing threshold, and the anti-rust treatment execution information is generated.

[0107] For example, the first preset bearing threshold is 30-35 kg, and the first bearing information is 34 kg. Therefore, the first bearing information meets the range of the first preset bearing threshold, and the anti-rust treatment execution information is generated.

[0108] For example, the first preset bearing threshold is 30-35 kg, and the first bearing information is 36 kg. Therefore, the first bearing information exceeds the range of the first preset bearing threshold, and the red light of the warning light group is turned on to remind the staff to reduce the number of fasteners in the charging box 2.

[0109] S4, send the anti-rust treatment execution information to the driving assembly and start the oil immersion timing.

[0110] When the first bearing information meets the first preset bearing threshold, the anti-rust treatment execution information is sent to the driving assembly, and the driving assembly drives the charging box 2 to start the anti-rust treatment, and simultaneously starts the timing to accurately obtain the duration of the fasteners for anti-rust treatment, so as to avoid that the anti-rust time is too long or too short to affect the anti-rust treatment effect.

[0111] S5, when the timing duration reaches the preset time threshold, generate a screen oil execution signal.

[0112] The preset time threshold can be set according to the actual processing condition, for example, the preset time threshold can be set to 3 minutes, 5 minutes, etc.

[0113] S6, send the screen oil execution signal to the screen oil assembly 3.

[0114] In some possible embodiments, in order to further improve the screen oil efficiency, the screen oil execution signal is divided into a draining oil sub-signal and a screen oil sub-signal, and draining oil is performed before screen oil to reduce the situation that too much anti-rust oil is poured into the screen bed 32 when the charging box 2 pours material into the screen bed 32.

[0115] In this case, step S6 includes:

[0116] S61, send the screen oil sub-signal to the screen oil assembly 3 to start the screen oil assembly 3.

[0117] Before the fasteners are poured into the screen bed 32, the screen bed 32 is started first, so that in the subsequent pouring process of the charging box 2, the fasteners that fall into the screen bed 32 first can timely follow the screen bed 32 to shake, so as to improve the screen oil efficiency of the screen bed 32 on the fasteners.

[0118] S62, send the draining oil sub-signal to the driving assembly and start the draining oil timing.

[0119] The oil draining sub-information is sent to the driving assembly, at this time the driving assembly acts and makes the charging box 2 separate from the rust-proof oil in the oil storage pool 1 and makes the charging box 2 rest above the oil storage pool 1, since the charging box 2 has the oil permeation hole 21, at this time the excess rust-proof oil in the charging box 2 can drip into the oil storage pool 1 through the oil permeation hole 21, thereby realizing the oil draining operation. Considering the processing time of the rust-proof treatment, it is necessary to time the oil draining operation.

[0120] S63, when the oil draining timing reaches the preset oil draining time, the oil draining discharge information is generated.

[0121] The preset oil draining time can be set according to the actual production situation, for example, the preset oil draining time is set to 1 minute, 2 minutes, etc.

[0122] S64, the oil draining discharge information is sent to the driving assembly.

[0123] When the oil draining is finished, the oil draining discharge information is sent to the driving assembly, and the driving assembly drives the charging box 2 to overturn to realize pouring the fasteners after oil draining into the sieve bed 32.

[0124] S65, based on the oil draining discharge information, the second bearing information of the charging box 2 is acquired in real time.

[0125] Since the fasteners in the charging box 2 are more likely to concentrate after the oil draining process, the guide plate 321 of the sieve bed 32 can concentrate to receive the fasteners from the charging box 2. Therefore, the second pressure sensor is arranged at the guide plate 321 of the sieve bed 32, and the second bearing information is acquired through the second pressure sensor to judge whether the charging box 2 is finished discharging.

[0126] S66-1, when the second bearing information is lower than the second preset bearing threshold, the reset information associated with the charging box 2 is generated.

[0127] S66-2, when the second bearing information is higher than the second preset bearing threshold, the alarm information is generated.

[0128] The sidewall of the sieve bed 32 is provided with an alarm, the alarm is connected with the controller, and the alarm includes but is not limited to a buzzer, when the second bearing information is higher than the second preset bearing threshold, the controller generates the alarm information and controls the alarm to alarm, so as to remind the staff to check in time.

[0129] S67, the reset information is sent to the driving assembly.

[0130] When the loading of the loading box 2 is completed, the second bearing information is lower than the second preset bearing threshold, at this time, the controller generates reset information associated with the loading box 2, and sends the reset information to the driving assembly, and the driving assembly drives the loading box 2 to reset, so as to facilitate the next round of fastener rust prevention treatment.

[0131] It should be noted that the step S61 and the step S62 can be executed synchronously, so as to improve the efficiency of the fastener rust prevention treatment.

[0132] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0133] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
