Description

Technical Field

[0001] This invention belongs to the technical field of copper strip processing devices in the chip lead frame production process, and particularly relates to a copper strip handling device, which is suitable for handling a whole bundle of copper strips during the chip lead frame manufacturing process. Background Technology

[0002] A patent titled "A Copper Strip Coil Transport Trolley" is disclosed in the existing Chinese patent database, with application number CN202022776882.4 and application date of 2020-11-26. This patent includes a trolley body with two symmetrically vertically connected column bodies on its surface. Each column body has a movable column inside. The top of each movable column is rotatably connected to a fixed box via a pivot. Movable boxes are symmetrically slidably connected to both sides of the fixed box. The fixed box has a groove, and slide rails are fixedly connected to both sides of the movable boxes, slidingly connecting the slide rails to the grooves. A sliding block is fixedly connected to the bottom of each movable box. The trolley body surface is equipped with movable boxes, fixed boxes, a two-way lead screw, a handwheel, a sliding block, slide rails, and through holes to facilitate the fixing of copper strip coils of different diameters. The column bodies, movable columns, magnets, limit blocks, tensioning springs, and pull rods are installed on the surface of the columns to ensure the stability of the copper strip coils when the trolley is going up or down slopes.

[0003] Copper sheet is a metal component with good ductility, high thermal conductivity and electrical conductivity. Therefore, it is the most commonly used material in cables and electrical and electronic components, and can also be used as a building material. The produced copper sheet needs to be wound and fixed by a rotating shaft. After being fixed, it forms a cylindrical copper strip before being transported.

[0004] During normal production and processing, copper strips often require transshipment for loading due to different processes. Existing transportation devices require workers to climb onto trolleys to secure copper strips at higher locations, which is time-consuming and labor-intensive. Furthermore, unloading requires unloading one strip at a time, resulting in low efficiency. Therefore, this invention provides a copper strip handling device that can quickly complete the loading of copper strips at higher locations and the batch unloading of copper strips. Summary of the Invention

[0005] To address the technical problems mentioned in the background section, the present invention provides a copper strip handling device.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] A copper strip handling device includes a frame-shaped body. Short connecting rods and long connecting rods are hinged to the lower two sides of the frame-shaped body, respectively. A long strip block for holding the copper strip is disposed inside the frame-shaped body. The upper end of the short connecting rod is hinged to one end of the long strip block, and the upper end of the long connecting rod is hinged to the other end of the long strip block. The short connecting rod, long connecting rod, long strip block, and lower part of the frame-shaped body cooperate to form a parallel four-bar linkage. An upwardly inclined lever is hinged to the free end of the long connecting rod extending to the bottom of the frame-shaped body. The lever is U-shaped. A horizontal waist-shaped groove is formed on the lower side of the frame-shaped body. A pin is provided on the inner side of the ear plate section of the lever, and the pin is slidably connected in the waist-shaped groove. Arc-shaped limiting seats are provided on both sides of the lower part of the frame-shaped body, with limiting holes on the limiting seats. A pin hole is formed on the long connecting rod, and the pin hole and the limiting hole are connected by a limiting rod. Wheels are provided at the bottom of the frame-shaped body.

[0008] During operation, when loading is required, the lever is rotated clockwise, causing the long connecting rod to rotate clockwise. The long strip block in the upper part of the frame body rotates to the bottom. The limiting rod passes through the limiting hole under the limiting seat to fix the long strip block to the limiting seat. The operator uses hoisting equipment to move the copper strip onto the long strip block. After the moving is completed, the lever is rotated counterclockwise to rotate the long strip block back to its original position. Then, the copper strip in the lower part of the frame body is laid. After the laying is completed, it is transported.

[0009] Compared with the prior art, the beneficial effects of the present invention are: due to the coordinated arrangement of the short connecting rod, the long connecting rod and the bending rod, the feeding operation of multi-layer coiled copper strip can be completed, saving the lateral space required for transportation and improving the efficiency of copper strip handling. The device is suitable for industrial production and has strong practicality.

[0010] As a preferred embodiment, the frame body is provided with a feeding mechanism, which includes a reducer. A horizontal rotating shaft is provided in the width direction of the frame body, and the free end of the rotating shaft is axially connected to the reducer. A first bevel gear is rotatably sleeved on both ends of the rotating shaft. A vertical lead screw is rotatably connected inside both sides of the frame body. A second bevel gear that meshes with the first bevel gear is rotatably sleeved at the lower end of the lead screw. A lead screw nut is connected to the lead screw, and a connecting ear plate extends from the side of the lead screw nut. The frame body is also provided with a guide member in the shape of a scoop. A sliding groove is provided on the side of the frame body located on the guide member. The connecting ear plate passes through the sliding groove. The two sides of the guide member are connected to the corresponding connecting ear plates. The bottom surface of the guide member is inclined downward. During unloading, the guide component is controlled to move upward by the unloading mechanism. When the inner bottom surface of the guide component touches the coiled copper strip, the guide component is controlled to move upward, so that the central shafts on both sides of the coiled copper strip are disengaged from the groove. Using the inclination of the bottom of the guide component and the gravity of the coiled copper strip itself, the coiled copper strip rolls down to the external storage device. After the lower layer of the coiled copper strip in the frame is unloaded, the lever is rotated to continue unloading the upper layer of the coiled copper strip. Due to the setting of the unloading mechanism, multiple layers of coiled copper strip can be unloaded layer by layer. It works in conjunction with the parallel four-bar linkage composed of the short connecting rod, the long connecting rod and the lever to efficiently complete the unloading of the coiled copper strip.

[0011] As a preferred embodiment, the bottom surface of the guide member has an inclination angle of 3-5°.

[0012] As a preferred embodiment, the guide member is provided with connecting protrusions on both sides, and a vertical stud is inserted between the connecting protrusion and the connecting ear plate, and a lock nut is screwed onto both ends of the bolt.

[0013] As a preferred embodiment, the upper surface of the long strip is provided with several semi-circular grooves spaced apart, and a central shaft is inserted into the copper strip, with the two ends of the central shaft protruding from the copper strip overlapping in the grooves.

[0014] As a preferred embodiment, a connecting rod is provided on the front side of the frame. Attached Figure Description

[0018] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-2 As shown, a copper strip handling device includes a frame-shaped frame 1. Short connecting rods 2 and long connecting rods 3 are hinged to the lower two sides of the frame-shaped frame 1, respectively. A long strip block 4 for placing copper strips is arranged inside the frame-shaped frame 1. The upper end of the short connecting rod 2 is hinged to one end of the long strip block 4, and the upper end of the long connecting rod 3 is hinged to the other end of the long strip block 4. The short connecting rod 2, long connecting rod 3, long strip block 4, and the lower part of the frame-shaped frame 1 cooperate to form a parallel four-bar linkage mechanism. The free end of the long connecting rod 3 extends to the bottom of the frame-shaped frame 1. The frame 1 has an upwardly inclined lever 5 with a U-shaped rod. The lower side of the frame 1 has a horizontal waist-shaped groove 6. The inner side of the ear plate section of the lever 5 has a pin, which is slidably connected in the waist-shaped groove 6. The lower sides of the frame 1 have arc-shaped limiting seats 7 with limiting holes 8. The long connecting rod 3 has a pin hole 9, which is connected to the limiting hole 8 by a limiting rod. The bottom of the frame 1 has a wheel 10.

[0020] Specifically, a feeding mechanism is provided inside the frame 1. The feeding mechanism includes a reducer 11. A horizontal rotating shaft 12 is provided in the width direction inside the frame 1. The free end of the rotating shaft 12 is axially connected to the reducer 11. A first bevel gear 13 is rotatably sleeved on both ends of the rotating shaft 12. A vertical lead screw 16 is rotatably connected inside both sides of the frame 1. A second bevel gear 14 that meshes with the first bevel gear 13 is rotatably sleeved at the lower end of the lead screw 16. A lead screw nut 15 is connected to the lead screw 16. A connecting ear plate 17 extends from the side of the lead screw nut 15. A guide member 18 is also provided in the shape of a scoop. A sliding groove 19 is provided on the frame 1 located on the side of the guide member 18. The connecting ear plate 17 is provided through the sliding groove 19. The two sides of the guide member 18 are connected to the corresponding connecting ear plate 17. The bottom surface of the guide member 18 is inclined downward. The bottom surface of the guide 18 is inclined at an angle of 3-5°. The angle of the guide 18 should not be too large to avoid the rolling speed of the coiled copper strip being too fast, which would cause damage to the coiled copper strip during the feeding process. Both sides of the guide 18 are provided with connecting protrusions 20. Vertical studs are inserted between the connecting protrusions 20 and the connecting ear plates 17. Locking nuts are screwed on both ends of the bolts. The connecting protrusions 20 and the connecting ear plates 17 are connected by locking with studs. This method has low cost and good locking effect. Several semi-circular grooves 21 are spaced apart on the upper surface of the long strip 4. A central shaft is inserted in the copper strip. The two ends of the central shaft protruding from the copper strip overlap in the grooves 21. A connecting rod 22 is provided on the front side of the frame 1. The setting of the connecting rod 22 facilitates the connection between the entire frame 1 and the external traction equipment, and improves the applicability of the entire device.

[0021] During the loading operation, the lever 5 is rotated clockwise, which drives the long connecting rod 3 to rotate clockwise, and the long strip 4 in the upper part of the frame 1 rotates to the bottom. Using the limiting rod passing through the limiting hole 8 below the limiting seat 7, the long strip 4 is fixed to the limiting seat 7. The operator uses the lifting equipment to move the copper strip onto the long strip 4. After the moving is completed, the lever 5 is rotated counterclockwise to rotate the long strip 4 back to its original position. Then, the copper strip is laid in the lower layer inside the frame 1. During the unloading operation, the guide 18 is controlled to move upward. When the inner bottom surface of the guide 18 touches the coiled copper strip, the guide 18 is controlled to move upward, so that the central shafts on both sides of the coiled copper strip are disengaged from the groove 21. Using the inclination of the bottom of the guide 18 and the gravity of the coiled copper strip itself, the coiled copper strip rolls down to the external storage device. After the lower layer of the coiled copper strip in the frame 1 is unloaded, the lever 5 is rotated to continue unloading the upper coiled copper strip.
