Description

Technical Field

[0001] This utility model relates to the field of electrical equipment manufacturing technology, and in particular to a copper busbar assembly and feeding mechanism for switchgear. Background Technology

[0002] In the manufacturing and assembly of switchgear, copper busbars are widely used as an important conductive component. Due to their considerable weight and volume, and smooth surface, traditional manual handling or simple mechanical conveying methods present several problems during assembly and loading: firstly, they are inefficient and labor-intensive; secondly, during conveying, especially during inclined loading, copper busbars are prone to slipping off the conveying mechanism due to inertia or vibration, potentially causing damage to the busbars themselves, affecting product quality, and posing significant safety hazards, such as injuring operators or damaging other equipment. Existing conveying mechanisms often lack effective positioning and anti-slip measures, cannot adapt to the stable conveying requirements of copper busbars of different specifications, and are difficult to adjust positions at multiple angles during conveying, resulting in inconsistent assembly accuracy. Furthermore, the rigid structural design of traditional conveying mechanisms easily leaves scratches on the copper busbar surface, affecting product appearance quality and service life. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a switchgear copper busbar assembly and feeding mechanism that can realize copper busbar feeding operation, improve the stability of copper busbar conveying, and reduce the risk of slippage.

[0004] This utility model is implemented using the following method: a switch cabinet copper busbar assembly and feeding mechanism, including U-shaped support frames at both ends, a support plate at the rear end between the U-shaped support frames at both ends, a first gantry frame at the rear end of the upper surface between the U-shaped support frames at both ends, a first telescopic cylinder embedded in the middle of the horizontal plate of the first gantry frame, a first U-shaped plate at the end of the telescopic rod of the first telescopic cylinder, a first conveying roller rotatably mounted inside the first U-shaped plate via a first bearing, support blocks at both ends of the upper surface of the support plate, a support conveying roller rotatably mounted between the support blocks at both ends via a second bearing, a strip-shaped groove opened on the inner side of the horizontal plate of the U-shaped support frame, a synchronous motor mounted inside the strip-shaped groove, a screw connected to the output end of the synchronous motor, a moving rod spirally mounted on the screw, and multiple conveying rollers equidistantly mounted between the moving rods at both ends.

[0005] Furthermore, a strip-shaped limiting opening is provided on the side of the strip-shaped groove, and a guide block is provided on the outer side of the moving rod that is embedded in the strip-shaped limiting opening.

[0006] Furthermore, a second gantry frame is provided at the rear end between the moving rods at the left and right ends. A second telescopic cylinder is embedded in the middle of the horizontal plate of the second gantry frame. A second U-shaped plate is provided at the end of the telescopic rod of the second telescopic cylinder. A second conveying roller is rotatably provided between the two vertical plates of the second U-shaped plate via a third bearing. A third conveying roller is rotatably connected between the lower end of the two vertical plates of the second gantry frame via a fourth rotating shaft.

[0007] The beneficial effects of this utility model are as follows: This utility model achieves stable conveying and height adjustment of copper busbars through the coordinated action of U-shaped support frame, first telescopic cylinder and multiple sets of conveying rollers. Combined with the synchronous motor driven moving rod structure, it realizes adaptive adjustment of conveying width, effectively preventing copper busbars from slipping during inclined feeding, and improving assembly efficiency and safety.

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] Please see Figures 1 to 3 As shown, this utility model provides an embodiment: a copper busbar assembly and feeding mechanism for a switch cabinet, including U-shaped support frames 1 at both ends, a support plate 2 at the rear end between the U-shaped support frames 1 at both ends, a first gantry frame 3 at the rear end of the upper surface between the U-shaped support frames 1 at both ends, a first telescopic cylinder 31 embedded in the middle of the horizontal plate of the first gantry frame 3, a first U-shaped plate 32 at the end of the telescopic rod of the first telescopic cylinder 31, a first conveying roller 33 rotatably disposed in the first U-shaped plate 32 via a first bearing, support blocks 34 at both ends of the upper surface of the support plate 2, a support conveying roller 35 rotatably disposed between the support blocks 34 at both ends via a second bearing, a strip groove 4 opened on the inner side of the horizontal plate of the U-shaped support frame 1, a synchronous motor (not shown) disposed in the strip groove 4, a screw 41 connected to the output end of the synchronous motor, a moving rod 42 spirally sleeved on the screw 41, and multiple conveying rollers 43 equally spaced between the moving rods 42 at both ends.

[0013] The U-shaped support frame refers to a frame structure with a U-shaped cross-section, which can be formed by bending steel plates, and is used to provide stable foundation support for the conveying mechanism. The first telescopic cylinder is a drive element that can extend and retract vertically, which can be a pneumatic cylinder or a hydraulic cylinder, used to adjust the height of the first conveying roller to accommodate different tilt angles. The support conveying roller is a cylindrical rotating component horizontally installed between the support blocks, which can be a metal roller with a rubber-coated surface, used to support the copper busbar and reduce sliding friction. The strip-shaped groove is a long, strip-shaped cavity extending along the inner side of the U-shaped support frame, which can be formed by milling, and is used to house the synchronous motor and transmission components. The synchronous motor is an electric motor whose speed is synchronized with the power supply frequency, which can be a permanent magnet synchronous motor, used to precisely control the rotational speed of the screw. The moving rod is a linear motion component with internal threads, which can be machined from aluminum alloy profiles, used to convert the rotational motion of the screw into horizontal displacement. Conveyor rollers are cylindrical conveying components arranged in parallel between moving rods. Specifically, steel rollers with anti-slip textures on the surface can be used to form a continuous conveying plane and restrict the lateral movement of the copper busbars.

[0014] Specifically, when the synchronous motor drives the screw to rotate, the moving rod moves horizontally along the strip groove, causing the conveyor roller assembly to form a conveying channel with an adjustable width. When the copper busbar is placed on the conveying plane formed by the support conveyor roller and the conveyor roller, the first telescopic cylinder adjusts the height of the first conveyor roller according to the feeding angle, so that the copper busbar receives auxiliary support in the inclined section. The spacing between the conveyor rollers can be automatically matched according to the length of the copper busbar, dispersing the load pressure through multi-point contact. During the movement of the copper busbar, the anti-slip texture and the rubber coating work together to increase the coefficient of friction, preventing displacement due to inertia.

[0015] Compared to existing technologies, traditional fixed conveying devices require manual adjustment of the roller spacing, while this solution achieves automatic adjustment of the conveying width through a synchronous motor and screw mechanism. Conventional conveying mechanisms only have a single row of rollers in the inclined section, while this solution uses a liftable first conveying roller and a support conveying roller to form a dual-point positioning, significantly improving the stability of the copper busbar. Existing technologies often rely on increasing friction materials for anti-slip measures; this solution achieves active anti-slip by dynamically adjusting the width of the conveying plane and using a multi-point contact design, maintaining conveying efficiency while achieving active anti-slip.

[0016] Through the above technical solution, this application effectively solves the slippage problem of copper busbars during inclined conveying, and adapts to the conveying needs of copper busbars of different sizes through an adjustable conveying plane. The multi-point support structure reduces local pressure and avoids indentation damage to the copper busbar surface. The automated adjustment function reduces the number of manual interventions, improves the continuity of assembly operations, and eliminates the risk of drops caused by manual handling.

[0017] Please continue reading. Figure 1 and Figure 2As shown, in one embodiment of the present invention, the strip groove 4 has a strip-shaped limiting opening 44 on its side, and the outer side of the moving rod 42 is provided with a guide block 45 that is embedded in the strip-shaped limiting opening 44.

[0018] Among them, the strip-shaped limiting port refers to a through opening opened along the length of the strip-shaped groove. Specifically, it can be formed into a through groove structure on the side of the U-shaped support frame by mechanical processing. Its width matches the size of the guide block and is used to limit the lateral displacement of the moving rod.

[0019] The guide block is a protruding structure fixed to the outer side of the moving rod. It can be rigidly connected to the moving rod by welding or bolting. Its cross-sectional shape is clearance-fitted with the inner wall of the strip-shaped limiting port, which can provide sliding guidance when the moving rod moves along the screw axis.

[0020] Specifically, when the synchronous motor drives the screw to rotate, the moving rod undergoes horizontal displacement under the helical transmission of the screw. At this time, the guide block is embedded in the strip-shaped limiting slot and slides along the length of the limiting slot, so that the movement trajectory of the moving rod is strictly limited to a preset straight path. This structure avoids radial swaying of the moving rod due to uneven force during transmission, thereby ensuring that the conveying plane composed of the conveying rollers always remains horizontal and preventing slippage of the copper busbar due to vibration of the conveying mechanism during inclined feeding.

[0021] Compared to existing technologies, traditional conveying mechanisms typically rely solely on screw drives for displacement control of moving parts, lacking constraints on the trajectory of the moving rod. When carrying heavy loads or moving at high speeds, the moving rod is prone to radial offset, causing the conveying plane to tilt or vibrate. This solution utilizes the sliding engagement of a strip-shaped limiting slot and a guide block to create a dual motion constraint mechanism, significantly improving the axial movement accuracy and anti-eccentric load capacity of the moving rod, and preventing it from detaching from the strip-shaped groove.

[0022] Through the above technical solution, this application can eliminate the unexpected displacement of the moving rod during the conveying process, ensuring that the copper busbar remains stable throughout the conveying process. The cooperation between the guide block and the limiting port effectively suppresses the impact of the conveying mechanism vibration on the position of the copper busbar, reduces equipment damage and safety hazards caused by the copper busbar slipping due to inertia, and at the same time reduces the frequency of manual intervention and improves the continuity of the feeding operation.

[0023] Please continue reading. Figures 1 to 3As shown, in one embodiment of the present invention, a second gantry frame 5 is provided at the rear end between the moving rods 42 at the left and right ends. A second telescopic cylinder 51 is embedded in the middle of the horizontal plate of the second gantry frame 5. A second U-shaped plate 52 is provided at the end of the telescopic rod of the second telescopic cylinder 51. A second conveying roller 53 is rotatably provided between the two vertical plates of the second U-shaped plate 52 via a third bearing. A third conveying roller 54 is rotatably connected between the lower end of the two vertical plates of the second gantry frame 5 via a fourth rotating shaft.

[0024] The second gantry frame is a frame structure consisting of a horizontal plate and two vertical plates on both sides, which can be achieved by welding or bolting. It is used to support the installation of the second telescopic cylinder and the second conveyor roller. The second telescopic cylinder is a drive component that can move linearly in the vertical direction. It can be implemented using a pneumatic cylinder or a hydraulic cylinder. It adjusts the height of the second conveyor roller by pushing the second U-shaped plate through a telescopic rod. The third bearing is a mechanical component that supports the rotation of the second conveyor roller. It can be implemented using a deep groove ball bearing or a needle roller bearing, which keeps the second conveyor roller rotating when in contact with the copper busbar to reduce friction. The fourth shaft is a rotating shaft that connects to the third conveyor roller. It can be made of carbon steel or alloy steel and is fixed at both ends to the vertical plates of the second gantry frame to provide stable support for the third conveyor roller.

[0025] Specifically, the second gantry frame is fixed to the rear end of the moving rod to form a stable support structure. The second telescopic cylinder drives the second U-shaped plate to adjust the vertical displacement of the second conveyor roller. When the copper busbar moves on the conveyor roller to the area of ​​the second gantry frame, the second conveyor roller forms a clamping area with the third conveyor roller through a downward pressing action, and the copper busbar is restricted between the two rollers to complete directional conveying. The third bearing keeps the second conveyor roller rotating in sync when in contact with the copper busbar, and the fourth rotating shaft supports the third conveyor roller to rotate synchronously. The two work together to eliminate the sliding friction on the surface of the copper busbar, and at the same time, the clamping action counteracts the displacement tendency of the copper busbar caused by inertia or vibration.

[0026] Compared to existing technologies, traditional conveying mechanisms rely solely on a single layer of rollers to support the copper busbars, lacking vertical constraint during inclined loading and leading to a risk of slippage. This solution integrates an adjustable-height second conveyor roller into a second gantry frame, forming a dynamic clamping structure with a fixed-position third conveyor roller. This provides continuous vertical restraint during conveying. Compared to simply increasing roller density, this structure can adjust the clamping gap in real-time according to the copper busbar thickness, avoiding excessive compression that could cause surface damage and effectively suppressing copper busbar slippage.

[0027] Through the above technical solution, this application forms an adjustable vertical clamping area during the copper busbar conveying process, eliminating the risk of the copper busbar slipping during inclined conveying, reducing surface impact damage caused by copper busbar displacement, and reducing the safety hazard of operators being injured by slipping copper busbars.

[0028] The telescopic cylinder and synchronous motor in this utility model are both existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0029] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
