Description

Technical Field

[0001] The utility model relates to a grabbing and anti-stacking device, in particular to a sheet material stacking and anti-stacking device, belonging to the technical field of stacking and grabbing. Background Art

[0002] When stamping some stacked products, the stacked materials are often grabbed by a robot and placed on the punch press. However, since some products will be adsorbed together, they will be stacked on the punch press during the grabbing process, affecting the stamping effect of the mold, so a grabbing and anti-stacking device is needed.

[0003] According to the patent number CN217497888U, an automatic stacking and feeding conveying mechanism for hardware sheets is disclosed, which includes a lifting rack, a grabbing robot arm, an adjustable conveyor belt and a pressure plate assembly; the lifting rack is equipped with hardware sheets to be loaded, the adjustable conveyor belt is arranged at the side end of the grabbing robot arm, the grabbing robot arm is arranged between the lifting rack and the adjustable conveyor belt, the pressure plate assembly is retractably arranged above the adjustable conveyor belt, and the adjustable conveyor belt includes a frame, a roller conveyor belt, a lateral adjustment assembly and a first lifting assembly.

[0004] The above scheme avoids the tediousness of people manually moving workstations during continuous stamping operations during implementation. However, it is difficult to issue an early warning of raw material stacking during implementation. When the robot grabs the stacked materials, due to vacuum, oil pressure and other reasons, two identical pieces may be adsorbed together and mistakenly grabbed into the mold, which may easily cause the mold to explode and result in cost losses. To this end, we provide a sheet stacking grabbing and anti-stacking device to solve the above problem. Utility Model Content

[0026] The embodiment of the utility model provides a sheet material stacking grabbing and anti-overlapping device.

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including an operating platform 1, the manipulator 12, the air pressure tube 13, the cylinder, the pressure scale 2, the buzzer alarm 3 and the punching machine involved in this application are all prior arts, and will not be described in detail in this application.

[0028] See also Figure 1 The top surface of the working platform 1 is fixedly connected with a placement plate 4, and a movable slide rail 11 is arranged above the placement plate 4. A group of manipulators 12 are slidably connected inside the movable slide rail 11. A pneumatic tube 13 is fixedly installed inside each manipulator 12. The pneumatic tube 13 is connected to an external cylinder. Through the push of the cylinder, the manipulator 12 can slide inside the movable slide rail 11 according to the set route, so as to grab the production materials. The height of the movable slide rail 11 from the placement plate 4 and the size of the manipulator 12 are all based on the actual production requirements. This application is only for style reference and is not a production standard.

[0029] A support frame 10 is provided below the working platform 1, and the pressure scale 2 is fixedly connected to the support frame 10. The support frame 10 can support multiple pressure scales 2 so that the device can remain stable when stamping the raw materials, thereby ensuring the normal operation of the device and improving the working efficiency.

[0030] See also Figure 1 and Figure 2 A pressure scale 2 is fixedly connected to the bottom surface of the working platform 1, and a buzzer alarm 3 is fixedly installed on the outer surface of the pressure scale 2. The pressure scale 2 is electrically connected to the buzzer alarm 3 and the punching machine through a data line. The staff first sets the single-piece weight value of the feeding on the pressure scale 2. If the feeding grabbing error occurs and the weight is overweight, the pressure scale 2 will automatically transmit the signal to the buzzer alarm 3. The buzzer alarm 3 starts to alarm after receiving the signal. At the same time, the pressure scale 2 will also transmit the signal to the punching machine, and the punching machine will automatically suspend the operation to avoid the punching operation from blowing up the wrong mold and reducing the loss of production costs.

[0031] See also Figure 1 , Figure 2 and Figure 3 A group of slide grooves 6 are provided on the top surface of the placement plate 4, and a fixing bolt 7 is slidably connected inside each slide groove 6. A group of threaded holes 8 are provided on the top surface of the working platform 1, and each fixing bolt 7 is threadedly connected to the threaded hole 8. The bottom end of the fixing bolt 7 is provided with a thread matching the threaded hole 8. The top of the fixing bolt 7 is a limiting cap, and the diameter of the limiting cap is larger than the groove width of the slide groove 6. When the fixing bolt 7 is threadedly connected to the threaded hole 8, the limiting cap at the top of the fixing bolt 7 will limit the placement plate 4, so that the placement plate 4 and the working platform 1 remain stably connected. When the placement plate 4 needs to be moved, the fixing bolt 7 can be turned out from the threaded hole 8.

[0032] A group of placement columns 9 are fixedly connected to the top surface of the placement plate 4. The placement columns 9 are made of rubber material and can support the placed production raw materials, thereby reducing the probability of excessive pressure during the stamping process causing damage to the raw materials.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A plurality of clamping mechanisms 5 are arranged above the placement plate 4, and the clamping mechanisms 5 include an adjusting block 501, and the adjusting block 501 is slidably connected to the placement plate 4. The staff can adjust the clamping mechanisms 5 according to the specifications of the raw materials required for the stamping operation, so that the clamping mechanisms 5 can clamp the raw materials, so that the raw materials can remain stable during the stamping operation, and avoid shaking that affects the normal progress of the stamping operation.

[0034] An adjusting slide 502 is provided inside the adjusting block 501, and a fixing bolt 503 is slidably connected inside the adjusting slide 502. A clamping block 504 is fixedly connected to the top surface of the adjusting block 501. The clamping block 504 can limit the production raw materials to keep the raw materials stable during the stamping process. The sliding of the fixing bolt 503 inside the adjusting slide 502 can change the position of the fixing bolt 503 limiting the adjusting block 501, so that the adjusting block 501 can slide on the top surface of the placement plate 4, and finally change the relative positions of multiple clamping blocks 504, so that the clamping blocks 504 can clamp production raw materials of various specifications, thereby improving the applicability of the device.

[0035] Please refer again Figure 3 A group of threaded holes 505 are provided on the top surface of the placement plate 4, and each fixing bolt 503 is threadedly connected to the corresponding threaded hole 505. A thread matching the threaded hole 505 is provided at the bottom end of the fixing bolt 503, and a limiting cap for limiting and fixing the adjustment block 501 is installed on the top of the fixing bolt 503. The diameter of the limiting cap is larger than the groove width of the adjustment slide 502. When the fixing bolt 503 is threadedly connected to the threaded hole 505, the limiting cap at the top of the fixing bolt 503 will squeeze the adjustment block 501, so that the adjustment block 501 and the placement plate 4 remain stably connected.

[0036] When the utility model is in use: the staff first fixes the placement plate 4 on the top surface of the working platform 1 through the fixing bolt 2 7 and the threaded hole 2 8, then sets the single-piece weight value of the feeding on the pressure scale 2, and then adjusts the relative position of the adjustment block 501 through the fixing bolt 1 503, so that the clamping block 504 can clamp the raw material that needs to be stamped, and then starts the manipulator 12, the manipulator 12 will grab the stacked production raw materials, and then place the raw materials between the clamping blocks 504, the clamping blocks 504 will clamp the raw materials, which is convenient for subsequent stamping operations. When the raw materials are placed on the placement column 9, the pressure scale 2 will weigh the placed raw materials. If the weight exceeds the set single-piece weight value, the pressure scale 2 will automatically transmit a signal to the buzzer alarm 3, and the buzzer alarm 3 will start to alarm after receiving the signal. At the same time, the pressure scale 2 will also transmit a signal to the punch press, and the punch press will automatically suspend the operation to avoid the stacked molds being blown up by the stamping operation and increase the loss of production costs.
