[0002] Copper strip is a widely used metallic material in electronics, construction, packaging, aerospace, marine engineering, and other fields. Due to its excellent electrical conductivity, corrosion resistance, and high thermal conductivity, copper strip plays an irreplaceable role in many critical applications.

[0003] In the current copper strip packaging process, after the copper strip is wound into a copper coil, the copper coil needs to be conveyed to the next packaging workflow, and this conveying process requires the use of a feeding rack. However, the existing feeding racks used to connect the upstream copper strip feed (i.e., copper coil) and the downstream material handling and turning station are not accurately positioned, which affects the efficiency of copper strip packaging.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, as Figures 1 to 8As shown, a cross-arm feeding rack includes a base 1, a material-picking cross-arm mechanism 2, and a lifting and braking mechanism 3. The material-picking cross-arm mechanism 2 is provided on the top of the base 1. A slewing bearing 4 is provided between the base 1 and the material-picking cross-arm mechanism 2, and the slewing bearing 4 is provided on the top surface of the base 1 through a bearing mounting seat 5. The lifting and braking mechanism 3 is provided on the base 1 to limit the material-picking cross-arm mechanism from continuing to rotate whenever it rotates 90°, so as to achieve precise positioning and improve the work efficiency of packaging copper strips.

[0030] Furthermore, such as Figure 3 and Figure 5 As shown, a bracket 6 is provided on either side of the bearing mounting seat 5 by bolts (or welding); an encoder 7 is provided on the bracket 6 by bolts, and a cylindrical gear 8 that meshes with the slewing bearing 4 is provided on the top of the encoder 7 via a rotating shaft. This gear is used to preset and measure the movement distance of the slewing bearing. When the movement distance reaches the preset value of the encoder, the cylindrical gear stops, thereby forcing the slewing bearing to stop rotating.

[0031] Furthermore, such as Figure 4 and Figure 6 , Figure 7 As shown, the material handling cross arm mechanism 2 consists of a material arm mounting base 201, material arms 202, a cover plate 203, and reinforcing ribs 204. The base plate of the material arm mounting base 201 is bolted to the top surface of the slewing bearing 4, and the cover plate 203 is provided on the material arm mounting base 201. Four material arms 202 are evenly distributed on the side plate of the material arm mounting base 201, and a fixing block 205 is embedded between each material arm 202 and the material arm mounting base 201. The base of the material arm 202 is connected to the cover plate 203 through reinforcing ribs 204. Four limiting blocks 206 are evenly distributed on the side plate of the material arm mounting base 201, and the four limiting blocks 206 and the four material arms 202 are distributed in a cross pattern to facilitate stopping the rotation of the material handling cross arm mechanism by means of a lifting brake mechanism. During installation, it should be noted that the lower part of the base of the material arm 202 is bolted to the outer wall of the material arm mounting base 201, and the upper part of the base of the material arm 202 is bolted to the vertical plate in the L-shaped reinforcing rib. Furthermore, the horizontal plate in the L-shaped reinforcing rib is placed on the cover plate 203, and bolts are used to connect it to the material arm mounting base 201 by passing through the horizontal plate and the cover plate from top to bottom.

[0032] In addition, such as Figures 1 to 4 As shown, the material is hung on the material arm 202.

[0033] Furthermore, such as Figure 1 , Figure 2 and Figure 8As shown, the lifting brake mechanism 3 consists of a hydraulic cylinder 301, a fixing plate 302, a fixing seat 303, a floating joint 304, a lifting cutter bar 305, and a flange 306. The fixing seat 303 is bolted (or welded) onto the base 1, with its bottom extending into the base 1. A through groove is provided on either side plate of the base 1 near the fixing seat 303 to facilitate the installation of the hydraulic cylinder and the fixing plate. The hydraulic cylinder 301 is mounted on the bottom surface of the fixing seat 303 via the fixing plate 302. The lifting cutter bar 305 and the floating joint 304 are arranged sequentially from top to bottom inside the fixing seat 303. The drive shaft in the hydraulic cylinder 301 extends into the fixing seat 303 and connects to the floating joint 304. The flange 306 is bolted to the top of the fixing seat 303, and the top of the lifting cutter bar 305 passes through the flange 306 and inserts into the limiting block 206 in the material arm mounting seat 202. In this system, a floating joint 304 is provided between the lifting cutter bar 305 and the hydraulic cylinder 301. When the cross arm mechanism needs to stop during rotation, the hydraulic cylinder 301 pushes the floating joint 304, which releases the shearing force and pushes the lifting cutter bar 305 upward to insert into the limiting block 206, thus stopping the cross arm mechanism. The floating joint 304 is characterized by its small size, easy installation, high durability, and high pressure resistance. It can play a role in buffering, vibration reduction, and improving the dynamic performance of the shaft system. It prevents the direction of force and the point of force application from being misaligned when the cylinder extends, and prevents the shaft from deforming / breaking, thus ensuring the life of the hydraulic cylinder and reducing the failure rate of the equipment.

[0034] Furthermore, the hydraulic cylinder 301 is a ROB standard medium and low pressure hydraulic cylinder.

[0035] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, a reduction motor 9 is bolted to the bottom surface of the side fixing seat in the bearing mounting seat 5, and a drive gear 10 that meshes with the slewing bearing 4 is provided on the top of the side fixing seat; the reduction motor 9 is connected to the drive gear 10 through a rotating shaft, and is used to drive the slewing bearing to rotate, thereby driving the material picking cross arm mechanism to rotate, so as to facilitate the material arm docking station.

[0036] Furthermore, the geared motor 9 is a helical geared motor, used to achieve efficient power transmission and deceleration.

[0037] Furthermore, such as Figure 5 As shown, the slewing bearing 4 is a single-row crossed roller slewing bearing; the slewing bearing 4 is rotatably connected to the bearing mounting seat 5 via a shaft; the bearing mounting seat 5 is detachably connected to the base 1 via bolts.

[0038] Working principle: The operator controls the start of the geared motor via a remote control console. The motor drives the drive gear to rotate, which in turn drives the slewing bearing to rotate. The rotation of the slewing bearing then drives the material handling cross arm mechanism to rotate. When the angular displacement reaches the preset value of the encoder, the encoder generates an interruption, causing the cylindrical gear to stop and the slewing bearing to stop rotating. At the same time, the hydraulic cylinder is activated. The piston rod in the hydraulic cylinder extends upward to push the floating joint. The floating joint moves upward to push out the lifting blade, so that the top of the lifting blade inserts into the limit block in the material arm mounting seat, thereby positioning and stopping the rotation of the material handling cross arm mechanism. At this time, the material handling cross arm mechanism has rotated 90°. One of the material arms with material hanging on it accurately connects to the downstream material handling and flipping station, while the other material arm with material hanging on it (i.e., copper coil) accurately connects to the upstream material receiving station. The accurate docking position improves the efficiency of packaging copper strips.
