Description

Technical Field

[0001] This utility model relates to the technical field of surface treatment equipment, and in particular to a servo-driven crane with a bellows cover. Background Technology

[0002] Currently, side-wall cranes on the market use ordinary motors to drive lifting and lateral movement. They are driven without protection and have the advantages of simple control and low cost. However, the disadvantages are that the movement process cannot achieve soft start and soft stop, which causes the hanging parts to swing violently. The workpieces hanging on the hanging parts are easy to fall off. At the same time, due to the violent swing of the hanging parts, the width and length of the bag equipment need to be larger, which increases the manufacturing cost and floor space of the equipment. During the lifting process, the moving parts of the boom are easily corroded by the electroplating environment, which affects the life of the crane. Utility Model Content

[0003] One objective of this invention is to provide a servo-driven crane with a bellows cover, which can achieve soft start and soft stop, reduce the swing of the hanger, save on equipment manufacturing costs and floor space, and effectively extend the service life of the crane in electroplating work environments.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A servo-driven crane with a bellows cover includes a frame and a traverse assembly, a lifting assembly, a sealing plate assembly, and an electrical control assembly mounted on the frame;

[0006] The lifting assembly includes a lifting servo motor, a lifting servo reducer, a lifting guide rail, and a lifting boom. The lifting servo motor is installed on the top of the lifting guide rail, and the drive end of the lifting servo motor is connected to the lifting servo reducer. The lifting servo reducer drives the lifting boom to move up and down along the lifting guide rail.

[0007] The traverse assembly includes a traverse servo motor, a traverse servo reducer, and a traverse slot. The traverse slot is connected to the drive end of the lifting servo reducer. The traverse servo motor is located above the traverse slot. The drive end of the traverse servo motor is connected to the traverse servo reducer. One end of the lifting boom is connected to the traverse slot.

[0008] The sealing plate assembly includes a PVC sealing plate and a bellows-style protective cover. The PVC sealing plate surrounds the outside of the frame, and the bellows-style protective cover is connected between the frame and the lifting boom.

[0009] The electronic control components include a rotating warning light.

[0010] As a preferred technical solution, a lower transverse guide wheel is rotatably connected to the bottom of the frame, a transverse bearing seat is installed at the rear end of the transverse groove, and an upper transverse guide wheel is rotatably connected to the lower end of the transverse bearing seat.

[0011] As a preferred technical solution, transverse PU wheels are installed on both sides of the transverse groove, and the drive end of the transverse servo reducer drives the rotation of the transverse PU wheels.

[0012] As a preferred technical solution, a lifting bearing seat is installed at the upper end of the frame, the drive end of the lifting servo reducer is connected to the lifting bearing seat, a lifting belt is connected to the drive end of the lifting servo reducer, the transverse groove is fixed on the lifting belt, the frame is provided with a lifting linear slide rail in the vertical direction, and the transverse groove slides along the lifting guide groove on the lifting linear slide rail.

[0013] As a preferred technical solution, the upper end of the frame is equipped with an anti-sling reverse winding limit switch and a front and rear over-limit switch, and the lower end of the frame is equipped with an anti-overlap photoelectric switch.

[0014] As a preferred technical solution, the frame is equipped with an upper over-limit sensor, a lower over-limit sensor, an upper positioning sensor, and a lower positioning sensor.

[0015] The beneficial effects of this utility model are as follows: It provides a servo-driven crane with a bellows cover. This servo-driven crane with a bellows cover can achieve soft stop in both lateral movement and lifting. When pneumatically moving and stopping, the vibration of the hanger is small, the workpiece is not easy to fall off, and the movement time is shortened. At the same time, the enclosed drive structure effectively protects the structure from corrosion in the electroplating environment and extends the service life of the crane.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3 As shown in this embodiment, a servo-driven crane with an accordion cover includes a frame 1 and a traversing assembly, a lifting assembly, a sealing plate assembly, and an electrical control assembly mounted on the frame 1. The lifting assembly includes a lifting servo motor 2, a lifting servo reducer, a lifting guide slot 3, and a lifting boom 4. The lifting servo motor 2 is mounted on the top of the lifting guide slot 3, and the drive end of the lifting servo motor 2 is connected to the lifting servo reducer. The lifting servo reducer drives the lifting boom 4 to move up and down along the lifting guide slot 3. The traversing assembly includes a traversing servo motor 5, a traversing servo reducer, and a traversing slot 6. The traversing slot 6 is connected to the drive end of the lifting servo reducer. The traversing servo motor 5 is located above the traversing slot 6, and the drive end of the traversing servo motor 5 is connected to the traversing servo reducer. One end of the lifting boom 4 is connected to the traversing slot 6. The sealing plate assembly includes a PVC sealing plate 7 and an accordion-style protective cover 8.

[0024] PVC, polyvinyl chloride, is a polymer formed by the free radical polymerization of vinyl chloride monomer under the initiation of peroxides, azo compounds, or under the action of light and heat. It appears as a white powder, non-toxic and odorless, with a relative molecular mass generally ranging from 50,000 to 110,000 (industrially produced pure PVC), and a relative density of 1.35 to 1.45. It has very low water absorption and air permeability (pure PVC), and is insoluble in water, gasoline, alcohol, and vinyl chloride, but soluble in ketones, esters, and chlorinated hydrocarbon solvents. PVC has good chemical resistance and electrical insulation, but poor impact resistance and is unstable to oxygen and heat, readily degrading.

[0025] In the vertical direction, the lifting servo motor 2, together with the lifting servo reducer, controls the lifting of the lifting boom 4, so that the lifting boom 4 can slide up and down along the lifting guide groove 3 under the drive of the transverse sliding groove 6; in the horizontal direction, the transverse sliding servo motor 5, together with the transverse sliding servo reducer, moves the transverse sliding groove 6 laterally. During the process of the transverse sliding groove 6 driving the lifting boom 4 to move, the bellows-style protective cover 8 effectively protects the drive structure from the corrosive effects of the electroplating environment. The entire frame 1 is surrounded by PVC sealing plate 7 for protection, which enhances the anti-corrosion effect.

[0026] In a more specific structure, a lower transverse guide wheel 10 is rotatably connected to the bottom of the frame 1, a transverse bearing seat 11 is installed at the rear end of the transverse groove 6, and an upper transverse guide wheel 12 is rotatably connected to the lower end of the transverse bearing seat 11; transverse PU wheels 13 are installed on both sides of the transverse groove 6, and the drive end of the transverse servo reducer drives the transverse PU wheels 13 to rotate; in the transverse state, the upper transverse guide wheel 12 and the lower transverse guide wheel 10 drive the frame 1 to move along the edge of the equipment.

[0027] PU wheels, also known as polyurethane wheels, are tires made of polyurethane (PU). Polyurethane is a polymer material with properties such as high elasticity, wear resistance, tear resistance, and impact resistance. PU wheels are typically made from polyurethane cast elastomer raw materials, and depending on the raw materials used, they vary in terms of yellowing resistance, wear resistance, transparency, and hardness.

[0028] A lifting bearing seat 14 is installed at the upper end of the frame 1. The drive end of the lifting servo reducer is connected to the lifting bearing seat 14. A lifting belt 15 is connected to the drive end of the lifting servo reducer. A transverse groove 6 is fixed on the lifting belt 15. A lifting linear slide rail 16 is provided along the vertical direction of the frame 1. The transverse groove 6 slides along the lifting guide groove 3 on the lifting linear slide rail 16. An anti-sling reverse winding limit switch 17 and a front and rear over-limit switch 18 are installed at the upper end of the frame 1. The lower end of the frame 1... An anti-overlap photoelectric switch 19 is installed at the end; an upper over-limit sensor 20, a lower over-limit sensor 21, an upper positioning sensor 22, and a lower positioning sensor 23 are installed on the frame 1; during lifting and lowering, the lifting belt 15 pulls the horizontal sliding groove 6 to lift and lower, and moves along the lifting linear slide rail 16. The upper positioning sensor 22 and the lower positioning sensor 23 sense the high and low positions. When the limit position is exceeded, the upper over-limit sensor 20 and the lower over-limit sensor 21 sense it and then perform an emergency stop.

[0029] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto.
