Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a welding device for forming shelf panels. Background Technology

[0002] As a core component of modern warehousing and logistics systems, the manufacturing quality of shelving shelves directly affects the load-bearing capacity, stability, and service life of the shelves. Traditional shelving shelves are mostly formed by folding steel plates and welding reinforcing ribs inside to increase the strength of the shelving shelves. A welding device for forming shelf panels, as disclosed in patent application number 202011456119.1, includes a fixed base and a positioning plate. The positioning plate is movably mounted on the upper outer surface of the fixed base. A side-rotating plate is movably mounted on one side of the positioning plate, and a connecting rod is provided between the positioning plate and the side-rotating plate. Two sets of sliding buckles are fixedly mounted on the lower outer surface of the positioning plate, and a first locking wheel is movably mounted on the inner side of the sliding buckles. A positioning bolt is movably mounted on the inner surface of the positioning plate near the sliding buckles. Traditional welding equipment often relies on manual placement of reinforcing ribs onto the surface of the shelf panel for positioning. This method is prone to deviations, resulting in inaccurate welding point positions, which affects the structural strength and safety of the shelf panel. Furthermore, due to the varying specifications of the reinforcing ribs on the shelf panel, fixed spot welders are less practical. Therefore, we propose a welding device for forming shelf panels. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a welding device for forming shelf panels. The device uses a sliding and adjustable positioning plate in conjunction with a pressure rod to automatically position the reinforcing ribs placed on the top surface of the shelf panel, thereby preventing welding deviations during subsequent spot welding. At the same time, the spacing between the spot welders can be easily adjusted, making it suitable for welding shelf panels of different specifications. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a welding device for forming shelf panels, comprising a frame and a frame; The frame has two fixedly mounted first linear motors on both sides inside. Each side of the first linear motor's moving part is provided with a bracket. The top of the bracket is connected to one side of the bottom surface of the placement frame. The placement frame is slidably installed inside the frame. Baffles are fixed on both the left and right sides of the top surface of the frame. A top plate is fixed between the two baffles. An adjustment unit is provided on the bottom surface of the top plate. An adjustment seat is slidably installed inside the adjustment unit. The frame is fixed to the surface of the adjustment seat. A pneumatic push rod is installed inside the frame. The bottom end of the pneumatic push rod is fixedly connected to the top surface of the spot welder. A positioning unit is provided inside the baffle. The device also includes a controller, which is fixed to the front side of the frame. The input ends of the first linear motor, pneumatic push rod, and spot welder are electrically connected to the output end of the controller, and the input end of the controller is electrically connected to the output end of an external power supply.

[0005] The first linear motor is started to adjust the distance between the two placement racks, so as to place the shelf panels of different specifications. Meanwhile, the pneumatic push rod drives the spot welder to descend and spot weld the reinforcing ribs on the top surface of the shelf panel.

[0006] Furthermore, the adjustment unit includes a second linear motor, a fixed frame, an electric telescopic rod, a sliding rod, a support frame, a fixed rail, and a limiting rod. The second linear motor is fixed to the bottom surface of the top plate. A fixed frame is provided on the bottom surface of the second linear motor's moving part. An electric telescopic rod is installed inside the fixed frame. The bottom end of the electric telescopic rod is connected to the middle of the top surface of the support frame. Sliding rods are provided on both sides of the top surface of the support frame and are slidably installed with the sliding grooves inside the fixed frame. Limiting rods are fixed at both ends of the inner side of the fixed rail. The limiting rods are slidably installed with the limiting grooves on the surface of the support frame. The outer side of the fixed rail is slidably installed with the adjustment seat. The input ends of the second linear motor and the electric telescopic rod are electrically connected to the output end of the controller. The electric telescopic rod is activated to adjust the height of the spot welder, while the second linear motor drives the spot welder to move horizontally to automatically spot weld multiple reinforcing ribs on the top surface of the shelf, thereby increasing the welding efficiency of the welding device.

[0007] Furthermore, the adjustment unit also includes a handle, a plug rod, a screw, and a socket. The bottom surface of the handle is fixed with a plug rod, and the sockets are evenly spaced on the top surface of the fixed rail. The plug rod passes through the through hole on the top surface of the adjustment seat and is inserted into the corresponding socket. The screw is rotatably mounted on one end of the inner side of the fixed rail and is threadedly connected to the screw hole on the surface of the support frame. Rotating the screw adjusts the spacing between the corresponding spot welders on the left and right sides to meet the welding requirements of the reinforcing rib widths on different shelf shelves. The plug rod is inserted into the socket to adjust the spacing between the spot welders, thereby controlling the distance between the weld points and improving the practicality of the welding device.

[0008] Furthermore, the positioning unit includes a third linear motor, a lifting plate, a fourth linear motor, a bracket, a main adjusting frame, a main bolt, and a positioning plate. The third linear motor is fixed inside the right side baffle. The surface of the moving part of the third linear motor is provided with a lifting plate that is slidably installed with the sliding groove inside the right side baffle.

The main adjusting frame has a screw hole with internal thread for the main bolt. The bottom surface of the main adjusting frame is fixed with a positioning plate. The input ends of the third and fourth linear motors are electrically connected to the output end of the controller. Rotating the main bolt installs the main adjusting frame in a suitable position outside the bracket. The third and fourth linear motors then drive the installed positioning plate to descend and move to the top surface of the shelf, thereby positioning the reinforcing ribs on the top surface of the shelf.

[0009] Furthermore, the positioning unit also includes an electric push rod, a fixed rod, a secondary bolt, a secondary adjusting bracket, and a pressure rod. The electric push rod is fixed inside the bracket, and a fixed rod is installed at the end of the electric push rod. A secondary adjusting bracket is slidably installed on the outside of the fixed rod, and a pressure rod is fixed on the bottom surface of the secondary adjusting bracket. The pressure rod is slidably installed in a through groove on the bottom surface of the bracket. A secondary bolt is installed in the threaded hole on the surface of the secondary adjusting bracket. The input end of the electric push rod is electrically connected to the output end of the controller. Rotating the secondary bolt installs the secondary adjusting bracket on the outside of the fixed rod. Activating the electric push rod drives the pressure rod to work with the positioning plate to automatically position the reinforcing ribs placed on the top surface of the shelf, thus preventing the problem of deviation that is easy to occur when manually positioning.

[0010] Furthermore, it also includes a placement base and a distance sensor. The placement base is fixed to the front side of the mounting frame, and the distance sensor is snapped into the interior of the placement base. The output of the distance sensor is electrically connected to the input of the controller. The distance sensor can detect the horizontal movement distance of the spot welder, thereby causing a shift in the placement spot welding position.

The insertion rod is inserted into the insertion hole to adjust the spacing between the spot welders, thereby controlling the distance between the weld points and improving the practicality of the welding device.

[0013] 3. The position of the positioning plate and the pressure bar are adjusted by the main adjustment frame and the auxiliary adjustment frame.
