Description

Technical Field

[0001] The invention belongs to the field of digital workshops, and in particular relates to a digital workshop assembly line simulation system. Background Art

[0002] As the complexity of modern products increases, their processes become more complex. Traditional assembly lines cannot meet the production processes of many specific products. This requires the design of the production line layout, process, and logistics to avoid waste of efficiency and cost. Production system simulation focuses on the simulation of production lines, processes, logistics, etc. to achieve optimization of workshop assembly lines.

[0003] After planning is completed, the workshop needs to simulate the use of the assembly line equipment to calculate the maximum working time of the assembly line equipment to avoid damage to the assembly line equipment due to excessive use. However, the following deficiencies exist in the actual operation process:

[0004] 1. When combining assembly line equipment, two sets of assembly line equipment are often brought together. This method can easily cause the goods to skew when passing between the conveyor belts of the two sets of assembly line equipment. In the existing technology, most of the time, the goods are straightened manually by staff or by mechanical adjustment, which has the problems of low efficiency and high operating costs.

[0005] 2. During the simulation operation, cameras are required to monitor and take photos to facilitate staff management. However, since the transportation distance of goods on the assembly line equipment is long and the position of the surveillance cameras is fixed, multiple sets of surveillance equipment are required, which is costly.

[0006] 3. When the assembly line transfers goods, the debris on the goods is easy to adhere to the surface of the conveyor belt, which will easily increase the wear of the conveyor belt over time, thereby aggravating the wear of the conveyor belt and shortening the frequency of maintenance and replacement. Summary of the Invention

[0007] The purpose of the present invention is to provide a digital workshop assembly line simulation system to solve the problems of low operating efficiency and high cost raised in the above background technology.

[0044] like Figure 1-6 As shown, a digital workshop assembly line simulation system includes:

[0045] A first support plate 1, a second support plate 2, a motor 3 and a plurality of conveying rollers 4 are provided on the first support plate 1. The first support plate 1 and the second support plate 2 are fixedly connected by a connecting plate 5. A plurality of conveying rollers 4 are covered with a conveyor belt 6.

[0046] The aligning mechanism 7 is used to straighten the goods that have deviated on the conveyor belt 6. There are two sets of aligning mechanisms 7, which are symmetrically arranged on the first support plate 1 and the second support plate 2. Each set of aligning mechanisms 7 includes a side support plate 71, a sector gear 72, a worm gear 73, a worm 74, a gear rod 75, a No. 1 spring 76, a guide rod 77, a fixing plate 78, a pressure wheel 79 and a straightening plate 710.

[0047] The monitoring mechanism 8 is installed above the first support plate 1 and is used to monitor the goods on the conveyor belt 6 in real time. The monitoring mechanism 8 includes a reciprocating screw 81, a sliding nut 82, a driven gear 83, a one-way bearing 84, a bracket 85 and a camera 86;

[0048] Cleaning mechanism 9, which is mounted on connecting plate 5 and is used to clean conveyor belt 6, includes a fixed rod 91, a sliding sleeve 92, a cleaning brush 93, a second spring 94 and an electromagnet 95;

[0049] The variable resistance component 96 is arranged on the pressure wheel 79. The variable resistance component 96 includes a spiral coil 961 and a power connection plate 962. The power connection plate 962 is electrically connected to the electromagnet 95. The spiral coil 961 is electrically connected to the external power supply. The electromagnet 95 and the spiral coil 961 are connected to the circuit in series.

[0050] The motor 3 is fixedly mounted on the first support plate 1 , and the output shaft of the motor 3 is connected to the conveying roller 4 . The conveying roller 4 is driven to rotate by the motor 3 , and the goods are then transported through the conveyor belt 6 .

[0051] The side support plate 71 is fixedly connected to the first support plate 1, and the sector gear 72 is rotatably connected to the side support plate 71. The gear rod 75 is slidably provided on the side support plate 71 along the length direction of the side support plate 71. The gear rod 75 has a tooth groove on the side wall near the sector gear 72 and meshes with the sector gear 72.

[0052] The sector gear 72 includes a rotating shaft for providing power, a worm gear 73 is fixedly connected to the rotating shaft, and a worm 74 is coaxially fixedly connected to the roller shaft of one of the conveying rollers 4, and the worm gear 73 and the worm 74 are meshed with each other;

[0053] The centralizing plate 710 is hinged to the side wall of the first support plate 1 by a hinge. The gear rod 75 is set through the first support plate 1, and the pressure wheel 79 is rotatably connected to the end of the gear rod 75. The pressure wheel 79 presses and rolls on the side wall of the centralizing plate 710.

[0054] The guide rod 77 is fixedly connected to the gear rod 75. The side support plate 71 adopts an L-shaped structure. The guide rod 77 slides through and is connected to the side support plate 71. The end of the guide rod 77 away from the gear rod 75 is fixedly connected to the fixed plate 78. The first spring 76 is wound around the gear rod 75, and the two ends of the first spring 76 are respectively connected to the fixed plate 78 and the side support plate 71.

[0055] The gear 75 of the present invention is rotated by the spring 76, and the gear 75 of the present invention is rotated by the spring 76. When the gear 75 of the present invention is rotated, the gear 75 of the present invention is rotated, and the gear 75 of the present invention is rotated. When the gear 75 of the present invention is rotated, the gear 75 of the present invention is rotated.

[0056] A track groove 11 is formed at the upper end of the first support plate 1 along its length. A sliding nut 82 is slidably fitted into the track groove 11. A reciprocating screw 81 is rotatably connected to the track groove 11. The sliding nut 82 is threadedly fitted onto the reciprocating screw 81. A bracket 85 is fixedly connected to the sliding nut 82. A camera 86 is mounted on the bracket 85.

[0057] The driven gear 83 is fixedly sleeved on the reciprocating screw 81 through a one-way bearing 84. The gear rod 75 passes through the track groove 11. The gear rod 75 has a tooth groove on its upper surface near the driven gear 83 and meshes with the driven gear 83.

[0058] During operation, the gear rod 75 can drive the driven gear 83 meshing with it to rotate back and forth during the reciprocating movement. Since the one-way bearing 84 can only be locked in one direction, it drives the reciprocating screw 81 to rotate intermittently. When rotating, the reciprocating screw 81 drives the sliding nut 82 threadedly matched with it to move along the length direction of the track groove 11, and then drives the camera 86 to move back and forth along the length direction of the conveyor belt 6. On the one hand, the monitoring shooting range of the camera 86 can be expanded, which is convenient for the staff to monitor the entire simulation system. On the other hand, the camera 86 moves in an intermittent moving manner, stops and takes pictures after moving a certain distance, avoiding problems such as blurred monitoring images and ghosting, ensuring the monitoring effect, and without setting up an additional power drive device, the monitoring position can be changed, thereby improving the utilization rate of kinetic energy.

[0059] The fixing rod 91 is fixedly connected between the first support plate 1 and the second support plate 2, the sliding sleeve 92 is slidably arranged on the upper surface of the connecting plate 5, and the sliding sleeve 92 is sleeved on the outside of the fixing rod 91, and the cleaning brush 93 is fixedly connected to the upper surface of the sliding sleeve 92. The cleaning brush 93 adopts a brown brush, which has less wear on the conveyor belt 6. The second spring 94 is wound around the outside of the fixing rod 91, and the two ends of the second spring 94 are respectively connected to the sliding sleeve 92 and the first support plate 1. The electromagnet 95 is fixedly installed on the second support plate 2. The sliding sleeve 92 is made of magnetic material and has opposite poles to the electromagnet 95. The cleaning brush 93 can clean the bottom of the conveyor belt 6 to prevent dust carried by the goods from adhering to and accumulating on the surface of the conveyor belt 6, aggravating the wear of the conveyor belt 6, and improving the service life of the conveyor belt 6, reducing the frequency of maintenance and replacement, and extending the continuous operation time of the assembly line equipment.

[0060] The spiral coil 961 is annularly wound on the circumferential side wall of the pressure wheel 79. Specifically, the spiral coil 961 includes an insulating tube, which has an annular structure and is sleeved on the circumferential side wall of the pressure wheel 79. The spiral coil 961 is spirally wound on the outer surface of the insulating tube. Insulating paint is sprayed on the surface of the spiral coil 961, and then the insulating paint near the side of the power connection plate 962 is scraped off, so that the spiral coil 961 can contact the power connection plate 962 for electrical conduction and prevent the spiral coil 961 from short-circuiting. The power connection plate 962 is fixedly embedded in the surface of the straightening plate 710. When the pressure wheel 79 rolls on the surface of the straightening plate 710, the power connection plate 962 contacts different positions of the spiral coil 961, so that the length of the spiral coil 961 connected to the circuit changes, that is, the resistance in the connected circuit changes, which is similar to the structure of a sliding rheostat. Since the electromagnet 95 and the spiral coil 961 are connected to the circuit in series, the magnetic force of the electromagnet 95 changes continuously.

[0061] During operation, when the pressure wheel 79 rolls on the side wall of the straightening plate 710, the power connection plate 962 contacts different positions of the spiral coil 961, so that the magnetic force of the electromagnet 95 continues to change, and the magnetic force on the sliding sleeve 92 continues to change, thereby driving the cleaning brush 93 to move back and forth along the fixed rod 91, thereby cleaning the conveyor belt 6. There is no need to set up an additional power drive device, which reduces costs and enables the transportation and cleaning of the conveyor belt 6 to operate in a coordinated manner.
