Description

Technical Field

[0001] This utility model relates to a receiving platform, and more particularly to a receiving platform for a robotic welding workstation. Background Technology

[0002] Robotic welding workstations, especially welding robot workstations, are an important component of modern automated welding production. They feature high precision, high efficiency, high safety, and flexibility, and are widely used in automobile manufacturing, home appliance manufacturing, and other fields.

[0003] Robotic welding workstations typically use conveyor belts to transport and weld workpieces, and then transport them away via the same conveyor belt after welding. Chinese patent application number 202320790926X discloses a robotic welding workstation comprising two support plates. Two transmission wheels are rotatably connected between the two support plates via a rotating shaft and bearings, and a conveyor belt is driven between the two transmission wheels. Multiple material unloading clamping assemblies are fixedly connected to the top of the conveyor belt. This patent utilizes an extrusion plate and extrusion wheels. The extrusion plate drives a sliding column to move via the extrusion wheels, which in turn drives a clamping plate to move. The two clamping plates approach each other and clamp and limit the workpiece, ensuring stability during welding and improving welding quality. When the extrusion wheel disengages from the extrusion plate, a first spring drives the clamping plate to reset via a sliding sleeve. The two clamping plates release the clamping force on the workpiece, which then moves with the conveyor belt and falls into a receiving box at the bottom. This achieves automatic material unloading, improving mechanization and processing efficiency. However, after the conveyor belt moves the workpiece above the receiving box, the workpiece falls directly into the receiving box. If the receiving box is too close to the conveyor belt, the number of workpieces that the receiving box can receive is limited. If the receiving box is too far from the conveyor belt, the workpiece is easily damaged when it falls into the receiving box. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a receiving platform for a robotic welding workstation that can change its position according to the amount of workpieces received, making it convenient for collection.

[0005] The technical solution is as follows: A receiving platform for a robotic welding workstation includes a base, support frames, an electric slide rail, a tray, a pressure sensor, a connecting frame, a moving plate, and omnidirectional brake wheels. The workstation is equipped with a conveyor belt and a welding robot. An electric clamping assembly is installed on the conveyor belt to clamp the workpiece. The conveyor belt then moves the workpiece to the welding station for welding by the welding robot. A base is installed at the front of the bottom of the workstation, located below and in front of the conveyor belt. Two support frames are symmetrically installed on both the front and rear sides of the base. An electric slide rail is installed inside the support frame. A support plate is connected between the sliding parts of the electric slide rail on the left and right sides. A pressure sensor is installed on the support plate. The pressure sensor is connected to the electric slide rail via a controller. A groove adapted to the support plate is opened on the base. When the support plate is moved to the bottom, it can move into the groove, so that the top of the support plate is at the same height as the top of the base. A universal brake wheel is installed at the bottom of the connecting frame. The connecting frame can be moved onto the base via the universal brake wheel. A movable plate is slidably connected to the connecting frame. The movable plate can receive and place the workpiece conveyed by the conveyor belt.

[0006] Furthermore, it also includes a pressing assembly. The pressing assembly is provided on the top of the support frame. The pressing assembly is used to stabilize the position of the connecting frame. The pressing assembly includes a fixed plate, a guide rod, a contact plate, and a return spring. The fixed plate is connected to the top of the support frame. The guide rod is connected to the fixed plate. The contact plate is slidably connected to the guide rod. The contact plate can contact the connecting frame. A return spring is connected between the contact plate and the fixed plate. The return spring is wrapped around the outside of the guide rod.

[0007] Furthermore, it also includes a limiting plate, which is connected to the rear top of the base and limits the rearward movement of the connecting frame.

[0008] Furthermore, it also includes a sponge pad. The top of the moving plate is equipped with a sponge pad, which has a cushioning effect and protects the falling workpiece from damage.

[0009] Furthermore, it also includes baffles. Baffles are connected to the lower parts of the front and rear sides of the connecting frame. The baffles slide through the moving plate and can block the workpiece on the moving plate to prevent the workpiece from falling off the moving plate.

[0010] Furthermore, it also includes a handle; a handle is installed on the upper front side of the connecting frame, which allows the connecting frame to be moved easily.

[0011] The beneficial effects of this utility model are as follows: This utility model uses an electric slide rail to move the pallet to its highest point, bringing the moving plate close to the conveyor belt. The moving plate can then collect the workpieces falling from the conveyor belt without damaging them. As the number of workpieces on the moving plate increases, the pressure sensor detects the pressure change and the controller can control the electric slide rail to move the pallet downward, causing the moving plate to move down a certain distance. In this way, the moving plate can automatically move downward according to the amount of workpieces received, thereby receiving more workpieces. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example: A receiving platform for a robotic welding workstation, such as... Figure 1-3As shown, the workstation includes a base 2, support frame 3, electric slide rail 4, pallet 5, pressure sensor 6, connecting frame 7, moving plate 8, universal brake wheel 9, limit plate 11, and sponge pad 12. The workstation 1 is equipped with a conveyor belt 102 and a welding robot 101. An electric clamping assembly 103 is installed on the conveyor belt 102 to clamp the workpiece. The conveyor belt 102 then moves the workpiece to the welding station for welding by the welding robot 101. The base 2 is installed at the front bottom of the workstation 1, located below and in front of the conveyor belt 102. Two support frames 3 are symmetrically installed on both the front and rear sides of the base 2. The electric slide rail 4 is installed inside the support frame 3. The pallet 5 connects the sliding parts of the electric slide rail 4 on both sides. The pressure sensor is installed on the pallet 5. 6. The pressure sensor 6 is connected to the electric slide rail 4 via a controller. The base 2 has a groove adapted to the pallet 5. When the pallet 5 is moved to the bottom, it can move into the groove, so that the top of the pallet 5 is at the same height as the top of the base 2. The bottom of the connecting frame 7 is equipped with the universal brake wheel 9. The connecting frame 7 can be moved onto the base 2 via the universal brake wheel 9. The top rear side of the base 2 is connected to the limiting plate 11, which limits the backward movement of the connecting frame 7. The moving plate 8 is slidably connected to the connecting frame 7. The moving plate 8 can receive and place the workpiece conveyed by the conveyor belt 102. The top of the moving plate 8 is provided with the sponge pad 12, which has a cushioning effect and protects the falling workpiece from damage.

[0019] like Figure 1 and Figure 4 As shown, it also includes a pressing component 10. The pressing component 10 is provided on the top of the support frame 3. The pressing component 10 is used to stabilize the position of the connecting frame 7. The pressing component 10 includes a fixing plate 1001, a guide rod 1002, a contact plate 1003, and a return spring 1004. The top of the support frame 3 is connected to the fixing plate 1001. The guide rod 1002 is connected to the fixing plate 1001. The contact plate 1003 is slidably connected to the guide rod 1002. The contact plate 1003 can contact the connecting frame 7. The return spring 1004 is connected between the contact plate 1003 and the fixing plate 1001. The return spring 1004 is wrapped around the outside of the guide rod 1002.

[0020] like Figure 1As shown, it also includes a baffle 13. The baffle 13 is connected to the lower parts of the front and rear sides of the connecting frame 7. The baffle 13 slides through the moving plate 8 and can block the workpiece on the moving plate 8 to prevent the workpiece from falling off the moving plate 8.

[0021] like Figure 1 As shown, it also includes a handle 14, which is installed on the upper front side of the connecting frame 7, allowing the connecting frame 7 to be moved easily via the handle 14.

[0022] Initially, the connecting frame 7 is located on the base 2, and the electric slide rail 4 drives the pallet 5 to its highest position. After the welding robot 101 finishes welding the workpiece, the conveyor belt 102 moves the workpiece forward. After the workpiece moves above the moving plate 8, the electric clamping assembly 103 releases the workpiece, and then the workpiece falls down onto the moving plate 8. The pressure sensor 6 can detect the pressure on the moving plate 8. As the number of workpieces on the moving plate 8 increases, the pressure value detected by the pressure sensor 6 also changes. When the pressure value reaches a preset value... When the pressure sensor 6 receives the signal from the pressure sensor 6 (five preset values ​​are set in this embodiment, and the pressure sensor 6 will send a signal when each preset value is reached), the controller controls the electric slide rail 4 to move the pallet 5 downwards a certain distance, and the moving plate 8 follows. In this way, the position of the moving plate 8 can be automatically moved downwards according to the number of workpieces placed on it, which can prevent workpieces from falling from a height and causing damage, and also ensure that the moving plate 8 can receive more workpieces; after the moving plate 8 has finished receiving the workpieces, and the pallet 5 is in use, the controller controls the electric slide rail 4 to move the pallet 5 downwards a certain distance, and the moving plate 8 follows. 5. Move the tray 5 into the groove (if the tray 5 is not moved into the groove, the electric slide rail 4 can be controlled to move the tray 5 downward), then unlock the brake of the universal brake wheel 9, and then pull the connecting frame 7 forward through the handle 14, so that it is moved off the base 2 through the universal brake wheel 9, so that the workpiece on the moving plate 8 can be transferred or collected. At the same time, push another connecting frame 7 onto the base 2. When the connecting frame 7 moves onto the base 2, the connecting frame 7 can squeeze the contact plate 1003 to move upward, and the return spring 100 4. Deformation occurs, and the connecting frame 7 is pressed by the contact plate 1003, so that it can be stably pushed onto the base 2. When the connecting frame 7 moves to contact the limiting plate 11, the pushing of the connecting frame 7 stops, and the brake of the universal brake wheel 9 is released. Then, the electric slide rail 4 is controlled to drive the pallet 5 to move upward, thereby driving the moving plate 8 to move upward and close to the conveyor belt 102. The contact plate 1003 can prevent the connecting frame 7 from moving upward with the moving plate 8, thereby reducing the distance the workpiece falls from the conveyor belt 102 and preventing the workpiece from falling and being damaged.
