[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0039] See also Figure 1-Figure 11 The embodiment of the present invention provides a technical solution: a surface cleaning device for the production and processing of hardware tools, comprising a processing box 1, a support frame 2 is arranged inside the processing box 1, a cleaning component for cleaning the residue on the surface of the hardware tools is arranged on the surface of the support frame 2, a swing component for making the support frame 2 shake is arranged at the bottom of the support frame 2, and the processing box 1 is connected to the swing component through a cylinder 3;

[0040] The support frame 2 includes a support ring 201 and a connection cover 202. The connection cover 202 is fixedly connected to the bottom of the support ring 201. A collection box 4 with a water leakage groove is installed at the bottom of the connection cover 202.

[0041] A distribution box 5 is provided on the surface of the processing box 1, and the distribution box 5 is electrically connected to the cylinder 3 and the cleaning component through a wire.

[0042] Specifically, the cleaning component includes a supporting mesh plate 6, a first electromagnet assembly 7 and a second electromagnet assembly 8. The supporting mesh plate 6 and the first electromagnet assembly 7 are both fixedly connected to the inside of the supporting ring 201. The surface of the second electromagnet assembly 8 is provided with a through hole 9 for circulating the cleaning liquid inside the processing box 1. The second electromagnet assembly 8 is movably connected to the supporting ring 201. A blocking strip 10 is provided inside the processing box 1. A T-shaped plate 11 is fixedly connected to the surface of the second electromagnet assembly 8. A T-shaped groove 12 is provided on the surface of the supporting ring 201. The surface of the T-shaped plate 11 is movably connected to the inner side wall of the T-shaped groove 12. A reset spring 13 is fixedly connected to the surface of the supporting ring 201 through an extension block. One end of the reset spring 13 is fixedly connected to the surface of the second electromagnet assembly 8. A supporting protrusion 14 is fixedly connected to the surface of the supporting mesh plate 6. The cross-sectional shape of the supporting protrusion 14 is triangular.

[0043] In this embodiment, after the handle is placed on the supporting mesh plate 6, the supporting protrusion 14 contacts with the wrench line, so that the wrench is in a nearly suspended state. When the first electromagnet assembly 7 and the second electromagnet assembly 8 are energized, the wrench can be fixed by magnetic force, thereby preventing the wrench from falling during the shaking process. During the cleaning process, the second electromagnet assembly 8 is in a raised state, which can act as a partition to separate the wrenches, and has magnetism to fix the wrenches. The swinging component can make the supporting ring 201 shake, thereby making the cleaning component stir the water inside the treatment box 1, making it in a flowing state, and the second electromagnet assembly 8 The through hole 9 allows water to flow through during the shaking process, so that the water can flush the wrench and wash away the residue on its surface. Under the magnetic force of the first electromagnet assembly 7 and the second electromagnet assembly 8, the washed away metal residue can be adsorbed and will not float in the water. The blocking bar 10 can limit the second electromagnet assembly 8 to make it rise. During the lifting process, the reset spring 13 is pulled up. When the support ring 201 moves upward, the reset spring 13 can reset the second electromagnet assembly 8 to facilitate the subsequent collection of the wrench. When the power is on, the cleaning component can both fix the wrench and adsorb and clean the residue on its surface.

[0044] Specifically, the swing component includes a movable plate 15, a first electric push rod 16 and a second electric push rod 17, the cylinder 3 is fixedly connected to the surface of the processing box 1, one end of the output shaft of the cylinder 3 passes through the processing box 1 and is fixedly connected to the surface of the movable plate 15, the first electric push rod 16 and the second electric push rod 17 are both fixedly connected to the surface of the movable plate 15, the output shaft of the first electric push rod 16 is fixedly connected to a first connecting frame 18, the output shaft of the second electric push rod 17 is fixedly connected to a second connecting frame 19, the first connecting frame 18 and the second connecting frame 19 are symmetrically connected to both sides of the support ring 201, and a proximity switch 20 is provided on the surface of the movable plate 15 through the support plate. A dual-axis motor 21 is fixedly connected to the surface of the first connecting frame 18, and the two output shafts of the dual-axis motor 21 are movably connected to the support ring 201 and are movably connected to the first connecting frame 18. Reels 22 are fixedly sleeved on the surfaces of the two output shafts of the dual-axis motor 21. The first connecting frame 18 is movably provided with a rotating disk 23 through a fixed rod, and a connecting rope 24 is wound on the surface of the reel 22. The connecting rope 24 is fixedly connected to the surface of the support ring 201 through the rotating disk 23, and the support ring 201 is movably connected to the second connecting frame 19 on one side away from the first connecting frame 18. A limiting rod 25 is fixedly connected to the interior of the processing box 1, and the movable plate 15 is movably sleeved on the surface of the limiting rod 25.

[0045] In this embodiment, the support ring 201 descends in height, and the first connecting frame 18 and the second connecting frame 19 also descend in height under the action of the first electric push rod 16 and the second electric push rod 17. The second connecting frame 19 gradually approaches the proximity switch 20. After the proximity switch 20 is actuated, the cleaning component is actuated, and the cylinder 3 is energized, so that the movable plate 15 can reciprocate along the direction of the limit rod 25, thereby enabling the cleaning component to stir the water inside the processing box 1, and the residue on the surface of the wrench can be washed away. After the cleaning is completed, the first electric push rod 16 and the second electric push rod 17 are energized to make the support ring 201 move upward and reset. At the same time, under the action of the reset spring 13, the second electromagnet assembly 8 is reset. After that, the dual-axis motor 21 is energized to rotate the reel 22 on its output shaft, thereby reeling the connecting rope 24. The rotating disk 23 can change the direction of the connecting rope 24, thereby facilitating the support ring 201 to rotate around the output shaft of the dual-axis motor 21. The support ring 201 is tilted, and the wrench automatically slides off, which is convenient for collection.

[0046] Specifically, a screw 26 is connected to the surface of the collection box 4 , one end of the screw 26 movably passes through the edge of the collection box 4 and is threadedly connected to the connection cover 202 , and a magnet rod 27 is fixedly connected to the interior of the collection box 4 .

[0047] In this embodiment, after the cleaning component is powered off, the metal residues will enter the interior of the collection box 4 through the connecting cover 202 under the action of the water flow, and the water will be discharged through the drainage trough at the bottom. The metal residues will be adsorbed by the magnet rod 27 under the action of magnetic force and retained in the interior of the collection box 4. The collection box 4 is installed by screws 26, which can be easily disassembled and cleaned.

[0048] Specifically, a sealing ring 28 is fixedly connected to the surface of the collecting box 4 , and the surface of the sealing ring 28 is movably connected to the surface of the connecting cover 202 .

[0049] In this embodiment, a sealing ring 28 is fixedly connected to the surface of the collecting box 4. After the collecting box 4 is installed by means of screws 26, the sealing ring 28 is in close contact with the surface of the connecting cover 202, thereby preventing water leakage between the collecting box 4 and the connecting cover 202 during the process of the support ring 201 being reset upward.

[0050] When in use, place the semi-finished wrench that needs to be cleaned on the supporting mesh plate 6, and the triangular supporting protrusion 14 on the supporting mesh plate 6 can prop up the wrench, and the supporting protrusion 14 is in contact with the wrench line, so that more surfaces can be in a suspended state, and then the first electric push rod 16 and the second electric push rod 17 move downward, and the surface of the first connecting frame 18 on the first electric push rod 16 is fixedly connected with the dual-axis motor 21, and one side of the support ring 201 is movably sleeved on the two output shafts on the dual-axis motor 21, and the ends of the two output shafts are evenly movably connected to the first connecting frame 18. The first connecting frame 18 moves downward, and the height of one side of the support ring 201 can be lowered by the dual-axis motor 21, and the other side of the support ring 201 is movably connected to the second connecting frame 19, and the first connecting frame 18 and the second connecting frame 19 move synchronously, so that the support ring 201 can keep descending horizontally;

[0051] The support ring 201 descends, which drives the cleaning parts to descend. The edge of the second electromagnet assembly 8 will contact the blocking bar 10. The blocking bar 10 limits the second electromagnet assembly 8, so that it moves relative to the support ring 201. The T-shaped plate 11 and the T-shaped slot 12 can play a guiding and limiting role. The reset spring 13 is stretched. The second connecting frame 19 is made of metal. The proximity switch 20 is located directly below the second connecting frame 19. The proximity switch 20 is a position switch that can be operated without mechanical direct contact with the moving parts. When the object approaches the sensing surface to the action distance, the switch can be operated without mechanical contact or any pressure. After the proximity switch 20 is activated, the first electric push rod 16 and the second electric push rod 17 are powered off, and the support ring 201 no longer moves downward. The first electromagnet assembly 7 and the second electromagnet assembly 8 are powered on to generate magnetic force, which can adsorb the wrench and fix it. At this time, the cleaning parts are all in the water in the processing box 1. The first electromagnet assembly 7 and the second electromagnet assembly 8 can adsorb some metal residues on the surface of the wrench to make it separate from the wrench.

[0052] The cylinder 3 can be energized after the first electromagnet assembly 7 and the second electromagnet assembly 8 through the time delay relay. After the cylinder 3 is energized, the output shaft is contracted to make the movable plate 15 reciprocate along the direction of the limit rod 25, so that the support ring 201 can drive the cleaning component to move. The second electromagnet assembly 8 is provided with a through hole 9, through which water can pass, and the water can be stirred during the movement, so that the water can be in a flowing state, so that the water can rinse the surface of the wrench and wash away the residue on the wrench. The washed away metal residue can be adsorbed by the first electromagnet assembly 7 and the second electromagnet assembly 8 to clean After completion, the first electric push rod 16 and the second electric push rod 17 are started to move the support ring 201 upward. After the second connecting frame 19 is disconnected from the proximity switch 20, the first electromagnet assembly 7 and the second electromagnet assembly 8 are powered off, and both lose their adsorption effect on the metal residues. During the rising process of the support ring 201, the water flow drives the metal residues into the interior of the connecting cover 202 and is discharged through the drain groove at the bottom of the collecting box 4. The metal residues passing through the collecting box 4 will be adsorbed on its surface under the action of the magnet rod 27. The collecting box 4 also has the ability to filter, and the unabsorbed residues can be retained in the collecting box 4.

[0053] After the support ring 201 is reset upward, the dual-axis motor 21 is started, and the reel 22 is rotated through the output shaft, thereby reeling the connecting rope 24. The rotating disk 23 can reverse the connecting rope 24 to facilitate the connecting rope 24 to pull up the support ring 201. The support ring 201 rotates around the output shaft of the dual-axis motor 21, the table top is tilted, and the wrench automatically slides down for easy collection. The distribution box 5 is used to supply power to each part.
