[0017] The present invention will be further described below with reference to the accompanying drawings:
[0018] like Figure 1-4As shown, an automatic casing loading and unloading forming equipment includes a feeding conveyor belt mechanism 1 and a servo hydraulic press 2; at least two servo hydraulic presses 2 are arranged side-by-side; the feeding conveyor belt mechanism 1 is located in front of the servo hydraulic presses 2, including a mounting frame 11 and at least two sets of conveyor belt assemblies 12 arranged front-to-back on the mounting frame 11; the number of conveyor belt assemblies 12 is the same as the number of servo hydraulic presses 2; the left ends of all conveyor belt assemblies 12 are located in the same longitudinal direction; the length of the conveyor belt assemblies 12 gradually increases from back to front, feeding different servo hydraulic presses 2 respectively; each set of conveyor belt assemblies 12 is provided with a limiting device 121 on its left end; each servo hydraulic press... The press 2 is equipped with a handling robot arm 3 and a material storage and changing mechanism 4 on the front side and the rear side corresponding to the feeding conveyor belt mechanism 1. The power output end of the handling robot arm 3 is connected to a first mounting plate 31 and a loading and unloading handling assembly 32 and a unloading and handling assembly 33 mounted on the first mounting plate 31. The loading and unloading handling assembly 32 is used to pick up materials from the conveyor belt assembly 12 and place them into the servo hydraulic press 2. The unloading and handling assembly 33 is used to remove the processed workpieces from the servo hydraulic press 2 and place them into the material storage and changing mechanism 4. The material storage and changing mechanism 4 includes a frame 41 and a material storage and handling robot arm 42 and two sets of material storage and lifting devices 43 mounted on the frame 41. The conveyor belts are arranged in a front-to-back configuration for placing stacked trays and controlling their lifting. The tray handling robot 42 moves trays from the rear tray lifting device 43 to the front tray lifting device 43. In this design, the right ends of the multiple conveyor belt assemblies 12 are located in the same longitudinal direction. Therefore, feeding can be achieved by having one operator place the workpiece onto the multiple conveyor belt assemblies 12 from the right end of the feeding conveyor belt mechanism 1. The conveyor belt assemblies 12 control the workpiece to move to the left, and the limiting device 121 restricts the workpiece's position. Each conveyor belt assembly 12 feeds one servo hydraulic press 2, while the handling robot arm 3 in front of each servo hydraulic press 2 controls the loading and unloading. The positions of the conveyor assembly 32 and the unloading and handling assembly 33 enable the loading of materials from the conveyor belt assembly 12 into the servo hydraulic press 2, and the removal of the processed workpieces from the servo hydraulic press 2 and their placement in the material tray at the upper end of the material tray lifting device 43 behind the material storage and changing mechanism 4. During normal operation, the loading and handling assembly 32 first picks up the workpiece to be processed from the conveyor belt assembly 12, the unloading and handling assembly 33 removes the processed workpiece from the servo hydraulic press 2, the loading and handling assembly 32 places the workpiece to be processed into the servo hydraulic press 2, and the unloading and handling assembly 33 places the processed workpiece into the material tray. When the material tray is full of workpieces, it is transported to the material tray lifting device 43 at the front by the material tray handling robot 42.
[0019] In this design, three servo hydraulic presses 2 are provided; three sets of conveyor belt assemblies 12 are provided; three sets of handling robotic arms 3 and material storage and changing mechanisms 4 are provided, and one operator can feed materials to three servo hydraulic presses 2 at the same time.
[0020] The limiting device 121 includes two first Z-axis cylinders 1211, a second mounting plate 1212, an X-axis cylinder 1213, and a baffle plate 1214. The two first Z-axis cylinders 1211 are fixed on the front and rear sides of the conveyor belt assembly 12, and their power output ends are connected to the second mounting plate 1212. The X-axis cylinder 1213 is mounted on the second mounting plate 1212, and its power output end is connected to the baffle plate 1214. When the workpiece is transported to the left, it is blocked and limited by the baffle plate 1214. After the sensor in the conveyor belt assembly 12 senses that there is material at this position, the conveyor belt assembly 12 stops running. The X-axis cylinder 1213 controls the baffle plate 1214 to push the workpiece to the right to the designated position. Then, the first Z-axis cylinder 1211 and the X-axis cylinder 1213 work together to control the baffle plate 1214 to reset, waiting for the loading and conveying assembly 32 to pick up the material.
[0021] The loading and handling assembly 32 includes a fixed base 321, a movable base 322, an elastic connecting assembly 323, and a pneumatic gripper 324. The fixed base 321 is fixed to the bottom of the first mounting plate 31. The movable base 322 is installed below the fixed base 321 through the elastic connecting assembly 323. The pneumatic gripper 324 is fixed to the bottom of the movable base 322. By setting the elastic connecting assembly 323 between the fixed base 321 and the movable base 322, damage to the workpiece or equipment is avoided when picking up and placing the workpiece.
[0022] The elastic connection assembly 323 includes two limiting screws 3231, a square post 3232, and two springs 3233. The heads of the two limiting screws 3231 abut against the top of the fixed seat 321, and the tails pass through the fixed seat 321 and are threadedly connected to the movable seat 322. The square post 3232 is mounted on the fixed seat 321 and slidably connected to the movable seat 322. The two springs 3233 are respectively mounted on the limiting screws 3231. The two ends of the springs 3233 abut against the fixed seat 321 and the movable seat 322 respectively. The structure of the unloading and conveying assembly 33 is the same as that of the loading and conveying assembly 32. The limiting screws 3231 are used to control the elastic movement stroke of the movable seat 322, and the square post 3232 is used as a guide for higher stability.
[0023] The material storage and pallet changing mechanism 4 is located on the left side of the handling robot arm 3; the right side of the frame 41 has two U-shaped mounting ports 411 distributed front and back; the two sets of material tray lifting devices 43 are respectively installed at the positions of the U-shaped mounting ports 411; the material tray handling robot arm 42 includes a Y-axis module 421 installed on the upper right side of the frame 41, a second Z-axis cylinder 422 installed on the power output end of the Y-axis module 421, and a material tray clamping cylinder 423 installed on the power output end of the second Z-axis cylinder 422. The material tray lifting device 43 includes a servo screw lifting drive device and a tray installed on the power output end of the servo screw lifting drive device. The material trays are stacked on top of the tray. After each material tray is taken out / placed, the servo screw lifting drive device controls the tray to rise / fall by the thickness of one material tray to ensure that the height position of the uppermost material tray remains unchanged, which facilitates the material tray handling robot arm 42 to pick up and place the material trays. Two U-shaped mounting ports 411 are set on the right side of the frame 41 for installing the material tray lifting device 43, which facilitates the operator to pick up and place the material trays.
[0024] The above description does not limit the technical scope of this invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this invention shall still fall within the scope of the technical solution of this invention.
