Description
TECHNICAL FIELD
[0001] The utility model mainly relates to the up and down material mechanism technical field, concretely relates to a laser machine auxiliary up and down material mechanism. BACKGROUND
[0002] In the traditional laser machine processing process, the up and down material work mostly relies on manual operation. The worker places the workpiece in the laser machine processing area, and then manually takes it down after processing. This way is inefficient because the speed of human operation is limited, and it is easy to get tired. For example, in a small part laser cutting workshop that needs frequent up and down material, the worker may spend a lot of time on carrying and placing parts, thereby limiting the actual working time of the laser machine and reducing the overall production efficiency.
[0003] In addition, the precision of manual operation is limited. When placing the workpiece, it is difficult to ensure that the workpiece is accurately placed in the processing position of the laser machine every time, which may cause processing errors. Moreover, when processing some high-precision workpieces, small shaking during manual carrying or deviation of the placement position may make the processed workpiece not meet the quality standard.
[0004] With the continuous improvement of the requirements of manufacturing industry on production efficiency and product quality, laser machine processing also needs more efficient and accurate up and down material method. Especially in large-scale production or in the scene where the processing precision requirement is very high, the demand for automatic up and down material mechanism is increasingly prominent. For example, in the laser micro-processing of electronic components, the part size is small and the processing precision requirement is high, so the traditional manual up and down material method is difficult to meet the production demand, and an auxiliary mechanism capable of accurate and rapid up and down material is needed.
[0005] Some existing automatic up and down material equipment may have the problems of complex structure and high cost. Although some of the equipment can realize automatic up and down material, their structure design is not compact enough, and they occupy a large space, which is not suitable for some processing workshops with limited space. Moreover, some equipment may have insufficient stability in conveying and clamping workpieces, such as workpieces falling easily during conveying or not being able to adapt well to workpieces of different shapes and sizes when clamping.

[0033] Refer to the attached Figures 1-6 A kind of auxiliary unloading mechanism of laser machine, including rack 1, feed conveyor 4 and unloading conveyor 5 are provided on rack 1, feed conveyor 4 is arranged in the directly above of unloading conveyor 5, lifting mechanism 2 is provided on rack 1, movable conveyor 3 is provided on the output end of lifting mechanism 2, clamping device 6 is symmetrically provided on rack 1, workpiece is conveyed to movable conveyor 3 by feed conveyor 4, clamping device 6 clamps and fixes the workpiece to be processed, after laser machine completes processing, lifting mechanism 2 drives movable conveyor 3 to descend to the position of unloading conveyor 5, and workpiece is conveyed to unloading conveyor 5.
[0034] The structure of feed conveyor 4, unloading conveyor 5 and movable conveyor 3 is same, in production and manufacturing process, same spare parts and manufacturing process can be used.For example, the spare parts of conveying unit 8 can be uniformly produced, which reduces the switching cost of mould and production equipment.For maintenance personnel, since being familiar with the conveying device of one structure, when fault occurs, the problem can be positioned and repaired more quickly.If certain pulley 82 or conveying belt 83 is damaged, maintenance personnel can replace it with the same spare parts, which reduces the maintenance difficulty and maintenance time.
[0035] The conveying direction of feed conveyor 4 and unloading conveyor 5 is opposite, and movable conveyor 3 can transport in two directions.In this way, a complete material flow path can be formed in space.Workpiece enters the processing area according to the set direction from feed conveyor 4, after processing, through the transfer of movable conveyor 3, the processed workpiece is conveyed out by unloading conveyor 5 in the opposite direction, which ensures the coherence and orderliness of the whole feeding and discharging process.For example, in a continuous production line, feed conveyor 4 conveys unprocessed workpiece from raw material stacking area, and unloading conveyor 5 conveys processed workpiece to finished product storage area.
[0036] The movable conveying device 3 includes a support frame 7, in which a plurality of conveying units 8 are arranged. All conveying units 8 are driven by a drive shaft 9. The conveying units 8 on the movable conveying device 3 are staggered with the feeding conveying device 4 and the unloading conveying device 5 and the conveying units 8 on the unloading conveying device 5. Figure 3 As shown, the conveying units 8 on the movable conveying device 3 partially overlap with the conveying positions of the conveying units 8 on the feed conveying device 4 and the unloading conveying device 5. This allows the workpiece to be smoothly transferred between different conveying devices. When the workpiece is transferred from the feed conveying device 4 to the movable conveying device 3, since the conveying units partially overlap, the workpiece can smoothly transition from one conveyor belt 83 to another conveyor belt 83. The staggered arrangement of the conveying units 8 allows more conveying units 8 to be arranged in a limited space, thereby improving space utilization. At the same time, through reasonable staggering and partial overlap, the workpiece can be supported and driven by multiple conveying units 8 at the same time during the conveying process, sharing the load during the conveying process, thereby improving the conveying efficiency and reducing the wear of a single conveying unit 8.
[0037] The conveying unit 8 includes a mounting frame 81 on which two pulleys 82 are rotatably mounted. A conveying belt 83 is sleeved between the two pulleys 82 . A pad 84 is provided below the conveying belt 83 . One of the pulleys 82 is connected to the drive shaft 9 .
[0038] The lifting mechanism 2 includes a screw rod 21 vertically rotatably mounted on the frame 1, a threaded sleeve 22 is provided on the screw rod 21 through a thread, and a lifting block 23 is connected to the outer side of the threaded sleeve 22. The lifting block 23 is used to install the movable conveying device 3. The frame 1 is also provided with a guide shaft 24 parallel to the screw rod 21, and a guide hole 25 is opened on the lifting block 23. The guide hole 25 is slidably mounted on the guide shaft 24 up and down.
[0039] The clamping device 6 includes a mounting plate 61, on which a first cylinder 62 is fixedly mounted. The piston rod of the first cylinder 62 extends out of the mounting plate 61 and is fixedly connected to the main clamping plate 63. A guide rod 64 is fixedly mounted on the main clamping plate 63. A linear bearing 65 is provided on the mounting plate 61. The guide rod 64 is slidably mounted in the linear bearing 65. Two second cylinders 66 are also provided on the mounting plate 61. The second cylinders 66 are located on both sides of the first cylinder 62. An auxiliary clamping block 67 is provided on the output end of the second cylinder 66.
[0040] Working principle:
[0041] First, the workpiece to be processed is conveyed by the feed conveying device 4 , which gradually transfers the workpiece to the movable conveying device 3 .
[0042] Then, the clamping device 6 symmetrically arranged on the rack 1 starts to work. The piston rod of the first cylinder 62 extends and pushes the main clamping plate 63 to move, in the process, the guide rod 64 slides along the linear bearing 65 to ensure the stability of the movement of the main clamping plate 63; at the same time, the two second cylinders 66 on both sides of the first cylinder 62 also drive the auxiliary clamping block 67 to act, and the main clamping plate 63 and the auxiliary clamping block 67 together clamp and fix the workpiece to be processed, so that the subsequent laser machine can process the workpiece.
[0043] After the workpiece is clamped and fixed, the laser machine starts to process the workpiece, and at this time, the movable conveying device 3 is kept in the corresponding position to provide stable support for the laser machine processing.
[0044] When the laser machine completes the processing of the workpiece, the lifting mechanism 2 starts to work. The screw rod 21 rotates under the drive of the motor, since the threaded sleeve 22 is threadedly connected with the screw rod 21, and the lifting block 23 is connected with the outer side of the threaded sleeve 22, and the lifting block 23 slides up and down along the guide shaft 24 parallel to the screw rod 21 through the guide hole 25 formed in the lifting block 23, so that when the screw rod 21 rotates, the threaded sleeve 22 and the lifting block 23 can be stably lowered, and in turn drive the movable conveying device 3 to descend to the position of the discharging conveying device 5.
[0045] Finally, the movable conveying device 3 conveys the processed workpiece to the discharging conveying device 5, and the discharging conveying device 5 conveys the workpiece to the designated position to complete the discharging operation.
[0046] The above-described embodiments only express certain implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application patent; it should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, the protection scope of the present application patent should be subject to the appended claims.
