[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] like Figure 1As shown, an automatic loading and unloading production line of this utility model includes a fixture loading mechanism 1, a multi-station production line 2, a material unloading and pushing mechanism 3, and an automatic unloading mechanism 4. The multi-station production line 2 includes a station operation control component, and each station of the multi-station production line 2 is connected to the station operation control component. The loading end of the multi-station production line 2 is connected to the fixture loading mechanism 1, and the unloading end of the multi-station production line 2 is connected to the automatic unloading mechanism 4. The material unloading and pushing mechanism 3 is connected to the unloading end of the multi-station production line 2 and is used to push the material at the unloading end of the multi-station production line 2 into the automatic unloading mechanism 4.
[0027] The jig loading mechanism 1 is used to load multi-layer material jigs 5 and automatically deliver them one by one to the multi-station production line 2. The multi-station production line 2 is used to transport the material jigs 5 to each station for personnel to assemble and process. The station operation control component is used to block the material jigs 5 at the corresponding station. After the assembly at each station is completed, the material jigs 5 are released. When all the materials in the material jigs 5 are assembled, they are sent to the unloading end of the multi-station production line 2. The unloading and pushing mechanism 3 then pushes the material jigs 5 into the automatic unloading mechanism 4. The automatic unloading mechanism 4 then completes the automatic stacking of the material magazines.
[0028] like Figures 2 to 4 As shown, the jig loading mechanism 1 includes a loading lifting cylinder 11, a loading lifting platform 12, a loading bin 13, and an alternating clamping cylinder assembly 14. The loading bin 13 is used to store material jigs 5. The alternating clamping cylinder assembly 14 is installed at the bottom of the loading bin 13 and alternately fixes the material jigs 5 of each layer. The loading lifting cylinder 11 is installed below the loading bin 13. The loading lifting platform 12 is connected to the output end of the loading lifting cylinder 11. The loading lifting cylinder 11 drives the loading lifting platform 12 to catch the falling material jigs 5 and transfer them to the multi-station production line 2.
[0029] Multi-layer material jigs 5 are stacked from top to bottom in the loading bin 13, and the bottom material jig 5 is fixed by the alternating clamping cylinder assembly 14. When the material is dropped, the alternating clamping cylinder assembly 14 is activated to release the bottom material jig 5. At the same time, the loading lifting cylinder 11 drives the loading lifting platform 12 to pass through the multi-station production line 2 to catch the falling material jig 5. Then the loading lifting cylinder 11 drives the loading lifting platform 12 to descend and place the material jig 5 onto the multi-station production line 2.
[0030] The alternating clamping cylinder assembly 14 includes a first clamping cylinder 15 and a second clamping cylinder 17. The output end of the first clamping cylinder 15 is connected to a first clamping arm 16, and the output end of the second clamping cylinder 17 is connected to a second clamping arm 18. Both the first clamping cylinder 15 and the second clamping cylinder 17 are connected to the bottom of the feeding bin 13. The first clamping arm 16 and the second clamping arm 18 are staggered to form a height difference, and the height difference between the first clamping arm 16 and the second clamping arm 18 corresponds to the distance between the two layers of material fixtures 5. The first clamping cylinder 15 and the second clamping cylinder 17 extend or retract alternately. The height difference between the first clamping arm 16 and the second clamping arm 18 facilitates the alternating fixation of the two layers of material fixtures 5. Before the material fixture 5 is to be dropped, the first clamping cylinder 15 drives the first clamping arm 16 to extend and fix the bottom layer of material fixture 5. When dropping, the second clamping cylinder 17 drives the second clamping arm 18 to extend and fix the next bottom layer of material fixture 5. At the same time, the first clamping cylinder 15 drives the first clamping arm 16 to retract, and the bottom layer of material fixture 5 loses support and falls onto the loading lifting platform 12.
[0031] like Figure 1 As shown, the workstation operation control component includes a blocking cylinder 21 and a control button 22. The blocking cylinder 21 is connected to the multi-station production line 2. A blocking arm is provided at the output end of the blocking cylinder 21. When the multi-station production line 2 starts, the blocking cylinder 21 drives the blocking arm to extend onto the production line 2. The control button 22 is connected to and controls the blocking cylinder 21. Operating the control button 22 causes the blocking cylinder 21 to retract. The blocking cylinder 21 and control button 22 work together to stop the material fixture 5 at each workstation when it slides to that station, facilitating assembly. After assembly, operating the control button 22 retracts the blocking cylinder 21, allowing the material fixture 5 to continue flowing.
[0032] like Figure 5 As shown, the feeding and pushing mechanism 3 includes a pushing bracket 31, a pushing transverse cylinder 32, a pushing lifting cylinder 33, and a pushing arm 34. The pushing bracket 31 is installed on the multi-station production line 2. The pushing transverse cylinder 32 is connected to the pushing bracket 31. The pushing lifting cylinder 33 is connected to the output end of the pushing transverse cylinder 32. The pushing arm 34 is connected to the output end of the pushing lifting cylinder 33. When pushing, the pushing lifting cylinder 33 drives the pushing arm 34 to contact the material fixture 5 of the multi-station production line 2.
[0033] Before the material fixture 5 reaches the unloading end, the pushing lifting cylinder 33 drives the pushing arm 34 to rise so that the material fixture 5 can pass normally. After the material fixture 5 reaches the unloading end, the pushing lifting cylinder 33 drives the pushing arm 34 to fall so as to contact one end of the material fixture 5. At the same time, the pushing transverse cylinder 32 drives the pushing lifting cylinder 33 to move towards the automatic unloading mechanism 4. The material fixture 5 falls into the automatic unloading mechanism 4 under the action of the pushing arm 34.
[0034] like Figure 6 and Figure 7 As shown, the automatic unloading mechanism 4 includes an unloading bin 41, an unloading lifting module 42, an unloading tray 43, and a single-layer material presence sensor 44. The unloading tray 43 is connected to the unloading lifting module 42, and the unloading bin 41 is connected to the unloading tray 43. The unloading bin 41 is connected to the unloading end of the multi-station production line 2. The single-layer material presence sensor 44 is connected to the top of the unloading lifting module 42. When the single-layer material presence sensor 44 detects a material fixture 5 on the top of the automatic unloading mechanism 4, it will provide feedback to control the unloading lifting module 42 to lower the unloading tray 43 by one layer of material fixture 5, making room for the next unloading material fixture 5 to be stacked.
[0035] The automatic feeding mechanism 4 also includes a feeding tray 43 equipped with a hopper clamp 45 and a material presence sensor 46, both of which are connected to the feeding tray 43. The hopper clamp 45 is used to clamp the feeding hopper 41 that is in contact with the feeding tray 43 to prevent the feeding hopper 41 from slipping. The material presence sensor 46 is used to sense whether there is a material fixture 5 on the feeding tray 43.
[0036] like Figure 1 As shown, the multi-station production line 2 includes a production line support 23, a conveyor motor 24, and a conveyor chain 25 for conveying material fixtures 5. The conveyor motor 24 is connected to the production line support 23, and the conveyor chain 25 is slidably connected to the production line support 23. The conveyor chain 25 is connected to the output end of the conveyor motor 24. The loading end of the production line support 23 is connected to the fixture loading mechanism 1, and the unloading end of the production line support 23 is connected to the automatic unloading mechanism 4. The unloading and pushing mechanism 3 and the station operation control components are all installed on the production line support 23. The conveyor motor 24 drives the conveyor chain 25, which in turn drives the material fixtures 5 to complete the automated operation from loading, assembly, and unloading.
[0037] The multi-station production line 2 also includes a loading position sensor 26 and a discharging position sensor 27, which are respectively connected to the loading end and the unloading end of the production line support 23. The loading position sensor 26 is used to sense whether there is a material fixture 5 output to the multi-station production line 2 from the fixture loading mechanism 1. The discharging position sensor 27 is used to sense whether the material fixture 5 has moved to the unloading end of the multi-station production line 2, so as to provide feedback to the unloading and pushing mechanism 3 to perform a pushing action.
[0038] The automated loading and unloading production line also includes a material placement table 6, which is installed on the side of the multi-station production line 2. The material placement table 6 is used to place the parts that need to be assembled at each station, making it convenient for personnel to pick them up and assemble them.
[0039] The working principle of an automated loading and unloading production line is as follows:
[0040] S1. When the equipment power is turned on, the operator clicks the start button. After the equipment is reset and started normally, the operator manually puts the material jig 5 into the jig feeding mechanism 1. The spring clip sensor of the feeding bin 13 of the jig feeding mechanism 1 senses the material and the bottom alternating clamping cylinder assembly 14 clamps and fixes the bin.
[0041] S2. When the material loading sensor 26 has no material signal, the material loading lifting cylinder 11 drives the material loading lifting platform 12 to rise, the second clamping cylinder 17 drives the second clamping arm 18 to extend, the first clamping cylinder 15 drives the first clamping arm 16 to retract, the bottom material fixture 5 falls to the material loading lifting platform 12, and the material loading lifting cylinder 11 descends.
[0042] S3. When the production line starts, the blocking cylinder 21 is activated. After the material fixture 5 moves to the first station, it stops. After the personnel pick up the material and assemble it, they press the stop control button 22. The blocking cylinder 21 descends. After the material fixture 5 flows to the second station, the blocking cylinder rises and blocks the next material fixture 5 again. After the workers at the second station finish their work, the previous actions are repeated.
[0043] S4. The material fixture 5 moves to the unloading end of the multi-station production line 2, and after the material fixture 5 flows to the unloading position sensor, the pushing lifting cylinder 33 descends, the pushing transverse cylinder 32 moves, and pushes the material fixture 5 to the unloading bin 41 of the automatic unloading mechanism 4. Then the pushing transverse cylinder 32 retracts, and the pushing lifting cylinder 33 rises.
[0044] S5. The automatic feeding mechanism 4's feeding tray 43 descends one layer, the pushing and traversing cylinder 32 repeats its action, and the feeding tray 43 stops descending after the feeding bin 41 is full, and the bin clamp 45 is released from the clamping state.
[0045] S6. Personnel manually remove the unloading bin 41, repeatedly place the empty unloading bin 41 into the automatic unloading mechanism 4, and then personnel repeatedly load materials.
[0046] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
