Description

Technical Field

[0001] This utility model relates to the field of electrical automation loading and unloading technology, specifically an electrical automation loading and unloading device with a current diversion structure. Background Technology

[0002] In manufacturing, the loading and unloading process is a key link on the production line, and its efficiency directly affects the speed and quality of the entire production process. Traditional electrical automated loading and unloading devices mostly adopt a single clamping structure, that is, the same clamping mechanism is responsible for both picking up materials from the raw material area and sending them to the processing area, and also for removing the materials from the processing area and placing them in the designated position after processing. Although this design has achieved automation to a certain extent, it still has many shortcomings in actual operation.

[0003] Firstly, traditional equipment requires frequent changes of clamping targets during the loading and unloading process. That is, the material is first clamped from the raw material area and sent to the processing area. After processing is completed, the material is removed from the processing area and sent to the designated location. While the clamping mechanism is sending the processed material to the designated location, the production equipment is in a waiting state, which is the so-called "gap period". The existence of this gap period significantly reduces the overall speed of processing and production, which seriously restricts the efficiency of the production line. Therefore, an electrically automated loading and unloading device with a diversion structure is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an electrically automated loading and unloading device with a current diversion structure to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An electrically automated loading and unloading device with a diversion structure includes a fixed platform, a processing table on top of the fixed platform, two conveyor belts on the top of the fixed platform located behind the processing table, a diversion unloading mechanism above the two conveyor belts, and a six-axis robot on the right side of the processing table on top of the fixed platform.

[0007] The diversion and feeding mechanism includes two side support plates fixedly installed on the top of the fixed platform. The two side support plates are respectively located on the outer sides of the two conveyor belts. Two first crossbars located above the two conveyor belts are fixedly installed between the two side support plates. Moving blocks are slidably installed on the outside of the two first crossbars. A U-shaped frame is fixedly installed on the rear surface of the moving block. Two second crossbars are fixedly installed between the U-shaped frame and the moving block. Connecting plates are slidably installed on the outside of the two second crossbars. A material clamping mechanism is provided at the bottom of the connecting plate. Two electric push rods are fixedly installed at the end of the U-shaped frame away from the moving block. The telescopic ends of the two electric push rods are fixedly connected to the connecting plate. A drive structure for driving the moving blocks to move left and right is provided between the two side support plates.

[0008] The beneficial effects of this utility model are: the drive mechanism drives the moving block to move the clamping mechanism left and right, the electric push rod pushes the connecting plate and the clamping mechanism forward to clamp the material on the processing table. After clamping, the electric push rod retracts, driving the clamping mechanism and the material to move backward, freeing up space for the six-axis robot to clamp new materials to the processing table, thus improving production efficiency.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the material clamping mechanism includes a hollow slot plate fixedly installed at the bottom of the connecting plate. A No. 1 motor is fixedly installed on the left side of the hollow slot plate. A bidirectional screw is fixedly installed at the output end of the No. 1 motor. The bidirectional screw is rotatably installed inside the hollow slot plate. Two sliders are slidably installed inside the hollow slot plate and are threaded on the external threads of the bidirectional screw. Clamping plates are fixedly installed on the surfaces of the two sliders.

[0011] Furthermore, the drive structure includes a second motor fixedly installed on the top of the moving block, a gear fixedly installed at the output end of the second motor, and a rack fixedly installed between the two side support plates, with the gear meshing with the rack.

[0012] Furthermore, side support plates are fixedly installed on the front surfaces of the two side support plates, and infrared sensors are fixedly installed inside the side support plates. The infrared sensors correspond to the position of the processing table. A signal receiver is fixedly installed on the front surface of the moving block, and a PLC controller electrically connected to the signal receiver is fixedly installed on the top of the moving block. The PLC controller is electrically connected to the second motor.

[0013] Furthermore, rubber plates are fixedly installed on opposite sides of both clamping plates, and the surface area of ​​the rubber plates is smaller than that of the clamping plates.

[0014] Furthermore, the width of the conveyor belt is greater than the maximum distance between the two clamps when they are fully extended. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1, such as Figures 1-4 As shown, an electrically automated loading and unloading device with a diversion structure includes a fixed platform 1, a processing table 2 on the top of the fixed platform 1, two conveyor belts 3 located behind the processing table 2 on the top of the fixed platform 1, a diversion unloading mechanism above the two conveyor belts 3, and a six-axis robot 4 located on the right side of the processing table 2 on the top of the fixed platform 1.

[0024] Specifically, the diversion and feeding mechanism includes two side support plates 5 fixedly installed on the top of the fixed platform 1. The two side support plates 5 are located on the outer sides of the two conveyor belts 3 respectively. Two first crossbars 6 located above the two conveyor belts 3 are fixedly installed between the two side support plates 5. Moving blocks 7 are slidably installed on the outside of the two first crossbars 6. A U-shaped frame 8 is fixedly installed on the rear surface of the moving block 7. Two second crossbars 9 are fixedly installed between the U-shaped frame 8 and the moving block 7. Connecting plates 10 are slidably installed on the outside of the two second crossbars 9. A material clamping mechanism is provided at the bottom of the connecting plate 10. Two electric push rods 11 are fixedly installed at the end of the U-shaped frame 8 away from the moving block 7. The telescopic ends of the two electric push rods 11 are fixedly connected to the connecting plate 10. A drive structure for driving the moving block 7 to move left and right is provided between the two side support plates 5.

[0025] Two first crossbars 6 are supported above the two conveyor belts 3 by two side support plates 5. The two first crossbars 6 restrict the moving block 7 to slide between the two side support plates 5. The connecting plate 10 is restricted to slide inside the C-shaped frame 8 by two second crossbars 9. The moving block 7 can be driven by the set drive mechanism to move the clamping mechanism left and right. At this time, the two electric push rods 11 unfold and push the connecting plate 10 and the clamping mechanism forward. The set clamping mechanism can clamp the processed material on the top of the processing table 2. After the material is clamped, the two electric push rods 11 retract and pull the connecting plate 10 backward. The connecting plate 10 drives the clamping mechanism and the material to move backward at the same time. After that, the drive mechanism drives the moving block 7 and the clamping mechanism to move left and right, so that the processed material can be diverted and placed on the top of the two conveyor belts 3 for transmission to the next station. When the two electric push rods 11 drive the clamping mechanism and the material to move backward simultaneously through the connecting plate 10, the six-axis robot 4 can start to clamp the unprocessed material and place it on the top of the processing table 2 to start a new round of processing operations, which significantly improves the overall speed of processing and production.

[0026] It should be noted that the specific model of the six-axis robot 4 is: KUKA KR 16 / 210. This robot supports a variety of end effectors (such as pneumatic grippers, vacuum suction cups, and welding guns).

[0027] Example 2, as Figures 3-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0028] The material clamping mechanism includes a hollow slot plate 12 fixedly installed at the bottom of the connecting plate 10. A No. 1 motor 13 is fixedly installed on the left side of the hollow slot plate 12. A bidirectional screw 14 is fixedly installed at the output end of the No. 1 motor 13. The bidirectional screw 14 is rotatably installed inside the hollow slot plate 12. Two sliders 15 are slidably installed inside the hollow slot plate 12 on the external threads of the bidirectional screw 14. Clamping plates 16 are fixedly installed on the surface of both sliders 15.

[0029] With this configuration, the No. 1 motor 13 drives the bidirectional screw 14 to rotate forward and backward inside the empty slot plate 12, which can make the two sliders 15 move closer and further away from each other. As the two sliders 15 move closer and further away from each other, they can drive the two clamping plates 16 to move closer and further away from each other, thereby enabling the two clamping plates 16 to perform the function of clamping and releasing materials.

[0030] Example 3, as Figures 1-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0031] The drive structure includes a second motor 17 fixedly mounted on the top of the moving block 7. A gear 18 is fixedly mounted on the output end of the second motor 17. A rack 19 is fixedly mounted between the two side support plates 5. The gear 18 meshes with the rack 19.

[0032] With this setup, the second motor 17 drives the gear 18 to rotate forward and backward on the surface of the rack 19, which in turn drives the moving block 7 to move left and right along the surface of the first crossbar 6.

[0033] Example 4, as Figure 1 and Figure 5 As shown, this embodiment is a further improvement based on embodiment 3, and its specific details are as follows:

[0034] Side support plates 20 are fixedly installed on the front surface of the two side support plates 5. Infrared sensors 21 are fixedly installed inside the side support plates 20. The infrared sensors 21 are positioned corresponding to the processing table 2. A signal receiver 22 is fixedly installed on the front surface of the moving block 7. A PLC controller 23 electrically connected to the signal receiver 22 is fixedly installed on the top of the moving block 7. The PLC controller 23 is electrically connected to the second motor 17.

[0035] With this configuration, when the moving block 7 moves, it can drive the signal receiver 22 to move. When the signal receiver 22 receives the signal from the infrared sensor 21, it will transmit the signal to the PLC controller 23. Then, the PLC controller 23 will control the second motor 17 to stop driving. After the second motor 17 stops driving, the clamping mechanism under the moving block 7 will be located directly behind the processing table 2, thereby improving the accuracy of the clamping mechanism in clamping the material.

[0036] Example 5, as Figure 4 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0037] Rubber plates (not shown in the figure) are fixedly installed on opposite sides of the two clamping plates 16. The surface area of ​​the rubber plates is smaller than that of the clamping plates 16.

[0038] This configuration, with rubber plates installed on opposite sides of the two clamping plates 16, prevents materials from slipping.

[0039] Example 6, as Figures 1-2 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0040] The width of conveyor belt 3 is greater than the maximum distance between the two clamping plates 16 when they are unfolded.

[0041] This design allows the conveyor belt 3 to easily catch the material released from the two clamping plates 16.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
