Description

Technical Field

[0001] The utility model relates to the technical field of factory assembly line equipment, in particular to a tray conveying mechanism. Background Art

[0002] The industrial assembly line is one of the most common production modes in modern manufacturing. Its main feature is that the production process is divided into multiple steps, and each step is completed by different machines or equipment. Under such a production mode, the application of logistics and transportation automation technology is of great significance. Logistics and transportation automation refers to the use of various automatic control technologies and equipment to realize the automated transportation and handling of products in the production process. In the industrial assembly line, logistics and transportation automation mainly involves the application of equipment such as conveyor belts, AGVs (automatic guided vehicles), and robots. Through these devices, products can be smoothly transferred from one production link to the next, and the automated distribution and handling of materials on the production line can be realized, improving production efficiency and quality.

[0003] When AGV transports goods to the workbench in the assembly line, it usually needs a motor to drive the transmission roller on the workbench to rotate so that the goods can be smoothly transferred to the workbench. If it follows the conventional method, each workbench must be equipped with a motor, which not only wastes space and power resources, but also directly increases the cost of production equipment.

Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0029] Embodiment 1

[0030] A tray conveying mechanism, such as Figure 1-2 As shown, it includes an automatic guided vehicle 1 moving on a track and a plurality of workbenches 2, wherein the plurality of workbenches 2 are arranged on one side of the track. The automatic guided vehicle 1 is provided with a conveying platform 3. The conveying platform 3 is provided with a plurality of first transmission rollers 31, and the two ends of two adjacent first transmission rollers 31 are connected by a chain to realize power transmission (such as Figure 7 As shown). A motor 32 for driving the first transmission roller 31 is provided on one side of the conveying platform 3. A plurality of second transmission rollers 21 are provided on the workbench 2, and power transmission is achieved by sleeve chains at both ends of two adjacent second transmission rollers 21. A driven friction wheel 212 is provided at one end of the second transmission roller 21 closest to the conveying platform 3. A power transmission device 33 is also provided on one side of the conveying platform 3. When the automatic guided vehicle 1 moves to the corresponding workbench 2, the power transmission device 33 contacts the driven friction wheel 212 to transmit kinetic energy.

[0031] In this embodiment, a plurality of power transmission devices 33 can be provided, and are provided on both sides of the transmission platform 3 , so that when the automatic guided vehicle 1 changes direction, power transmission with each workbench 2 can still be achieved.

[0032] Furthermore, the power transmission device 33 and the driven friction wheel 212 are located on the same side.

[0033] Furthermore, if Figure 2-5 As shown, the power transmission device 33 includes a servo electric cylinder 331, a moving component 332 and a rotating component 333. The rotating component 333 is rotatably connected to one end of the first transmission roller 31 closest to the workbench 2. The moving component 332 is slidably connected to the rotating component 333. The servo electric cylinder 331 is arranged on one side of the transmission platform 3, and drives the moving component 332 to push the rotating component 333 to rotate with one end of the first transmission roller 31 as the center.

[0034] Furthermore, the moving assembly 332 includes a slide rail 3321 disposed on one side of the conveying platform 3 , a moving plate 3322 slidably mounted on the slide rail 3321 , and a push rod 3323 mounted on the moving plate 3322 .

[0035] In the embodiment, the moving component 332 can be configured as other structures with a pushing function, such as a screw rod, a slider, and a motor.

[0036] Further, the rotating assembly 333 includes a rotating plate 3331, a first gear 3332, a second gear 3333 and an active friction wheel 3336, and a first connecting rod 3334 and a second connecting rod 3335 are rotatably mounted on the rotating plate 3331. The first gear 3332 is meshed with the second gear 3333. One end of the first connecting rod 3334 is connected to one end of the first transmission roller 31 closest to the workbench 2. The first gear 3332 is mounted on the first connecting rod 3334. The second gear 3333 and the active friction wheel 3336 are both mounted on the second connecting rod 3335.

[0037] Furthermore, a slide groove 33311 is provided on the rotating plate 3331. The slide groove 33311 is located on one side of the line between the first gear 3332 and the second gear 3333, and is not parallel to the line between the first gear 3332 and the second gear 3333, so that the push rod 3323 can exert a strong effect on the rotating plate 3331 when moving in the slide groove 33311, so that it rotates.

[0038] In this embodiment, the meshing form of the first gear 3332 and the second gear 3333 can be replaced by other structures that can realize the transmission mode.

[0039] Further, a slider 33221 is provided on one side of the movable plate 3322 close to the rotating plate 3331. The slider 33221 is slidably mounted in the slide groove 33311. Further, a movable block 33222 is provided on the lower surface of the movable plate 3322. The movable block 33222 is slidably mounted on the slide rail 3321.

[0040] Furthermore, if Figure 6 As shown, the push rod 3323 includes a push rod first section 33231 and a push rod second section 33232, and the push rod second section 33232 is slidably mounted inside the push rod first section 33231. One end of the push rod second section 33232 is mounted on the moving plate 3322. A heavy-load spring 33233 is sleeved on the outer side of the push rod second section 33232. Further, the servo electric cylinder 331 is connected to the push rod first section 33231.

[0041] In this embodiment, since the distance between the automatic guided vehicle 1 and the workbench 2 cannot be accurately measured when building the water flow workshop, there is a certain degree of error in the actual operation of the equipment, resulting in the servo electric cylinder 331 driving the push rod 3323 to move too far, which will cause the active friction wheel 3336 and the driven friction wheel 212 to be excessively squeezed and possibly damaged. Therefore, a heavy-load spring 33233 is mounted on the push rod 3323 to balance the force.

[0042] Working principle:

[0043] like Figure 8 As shown, when the automatic guided vehicle 1 moves to the corresponding workbench 2, the servo electric cylinder 331 drives the push rod 3323 to move, and the moving plate 3322 drives the rotating plate 3331 to rotate. Thereby, the second connecting rod 3335 is driven to rotate around the first connecting rod 3334, driving the second gear 3333 and the active friction wheel 3336 installed on the second connecting rod 3335 to rotate around the first connecting rod 3334, until the active friction wheel 3336 and the driven friction wheel 212 are in contact and squeezed. The second gear 3333 is driven by the first gear 3332 to rotate, thereby driving the active friction wheel 3336 to rotate, and the active friction wheel 3336 then transmits power to the driven friction wheel 212, and the driven friction wheel 212 drives the second transmission roller 21 to rotate. The whole process realizes power transmission.

[0044] The utility model transmits power to each workbench by arranging a power transmission device on one side of the transmission platform, so that there is no need to install a power device on each workbench, thus avoiding the waste of space and power resources and directly reducing the cost investment of production equipment.

[0046] In the present invention, unless otherwise clearly specified and limited, the first feature "on" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. "Multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
