Description

Technical Field

[0001] This utility model relates to a transport mechanism, and more particularly to a transport mechanism with data transmission and continuous lifting capabilities. Background Technology

[0002] In the automated manufacturing process of products, multiple components typically need to be precisely assembled according to specific steps. The handling, precise positioning, and information reading and recording of each processing stage are crucial. For example, in the automated production of water pumps, the motor cavity, stator assembly, rotor, etc., need to be assembled together using corresponding assembly processes. During the assembly process, the handling, positioning, and transmission and recording of processing information are key aspects. During the transfer process, the positioning, lifting, and data transmission of tooling are carried out sequentially, affecting the production line cycle time. Utility Model Content

[0003] To address the aforementioned problems, this application provides a transport mechanism, characterized in that it includes a conveying mechanism, a carrier, and a lifting mechanism. The conveying mechanism is capable of driving the carrier to move along the conveying direction of the conveying mechanism, and the lifting mechanism is located on the conveying mechanism. The lifting mechanism includes a first driving device, the output end of which moves perpendicular to the operating direction of the conveying mechanism. A signal reading and writing module is provided on the lifting mechanism, and the carrier includes a signal tag. When the carrier moves above the first driving device, the output end of the first driving device pushes the carrier away from the conveying mechanism, and simultaneously, the signal reading and writing module reads the signal tag information.

[0004] This application provides a transport mechanism that can simultaneously perform tooling lifting and data reading / writing. While data reading / writing and product lifting are being carried out, the conveyor mechanism operates continuously, thereby improving the product processing cycle time. Attached Figure Description

[0021] The transport mechanism of the exemplary embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0022] Reference Figure 1 This application provides a transport mechanism including a conveying mechanism 100, a lifting mechanism 200, a carrier 300, and a sensor 400. The transport mechanism is mounted on a workbench and is spaced a certain distance from the workbench. The carrier 300 is used to hold the product to be processed. The conveying mechanism 100 includes two parallel conveyor belts of equal height, and the conveying mechanism 100 can move the carrier 300. Along the conveying direction of the conveying mechanism 100, the lifting mechanism 200 is located on the conveying mechanism 100. A sensor 400 is fixedly mounted on the conveyor belt in front of the lifting mechanism 200, and the sensor 400 can sense whether the carrier 300 is in position. When the carrier 300 moves into position along the moving direction of the conveying mechanism 100, the sensor 400 transmits the sensing information to the central controller, which then controls the lifting mechanism 200 to lift the carrier 300, causing it to detach from the conveying mechanism 100 and enter the processing station directly above the lifting mechanism 200. When the processing step at this station is completed, the lifting mechanism 200 retracts, causing the carrier 300 to fall back to the conveying mechanism 100 and continue to flow away.

[0023] Reference Figure 2 and Figure 3The lifting mechanism 200 includes a first driving device 260, a third plate-shaped portion 280, a first plate-shaped portion 220, a limiting member 270, and a first stop portion 240. A clearance portion is provided in the middle region of the third plate-shaped portion 280. The cylinder of the first driving device 260 is disposed within the clearance portion. The output end of the first driving device 260 is fixedly connected to the first plate-shaped portion 220. The first plate-shaped portion 220 and the third plate-shaped portion 280 are arranged parallel to each other and connected by at least one retractable guide portion 250. The limiting member 270 includes a limiting portion 271 and a supporting portion 272. The supporting portion 272 includes a vertical plate-shaped portion and a horizontal plate-shaped portion. The first end of the vertical plate-shaped portion is vertically fixedly connected to the horizontal plate-shaped portion. The horizontal plate-shaped portion is fixedly connected to the third plate-shaped portion 280. The second end of the vertical plate-shaped portion is fixedly connected to the limiting portion 271.

[0024] Furthermore, the first drive device 260 is a cylinder.

[0025] Furthermore, in the lifting mechanism 200 provided in this application, the support part 272 includes a vertical plate-shaped part and a horizontal plate-shaped part that are fixedly connected to form an "L" shape, a "⊥" shape, an "I" shape or a similar shape, and the vertical plate-shaped part is fixedly connected to the limiting part 271 to form a "T" shape or a similar shape.

[0026] Furthermore, the third plate-shaped portion 280 is fixed to the worktable, and the output end of the first driving device 260 moves along a direction perpendicular to the operation of the conveying mechanism 100. Two limiting members 270 are symmetrically arranged on the third plate-shaped portion 280 of the lifting mechanism 200. The two limiting members 270 are located on both sides of the conveying mechanism 100, and the limiting portion 271 of the limiting member 270 is located above the conveying mechanism 100. The output end of the first driving device 260 can push the carrier 300 away from the conveying mechanism 100 until it abuts against the limiting portion 271.

[0027] Furthermore, the third plate-shaped portion 280 is also provided with a first stop portion 240, which includes a second drive device 241. The output end of the second drive device 241 moves in a direction perpendicular to the operation of the conveying mechanism 100. When the output end of the second drive device 241 moves to the highest position near the support member 300, the upper end of the output end of the second drive device 241 is higher than the lowest end of the support member 300, and the support member 300 can be intercepted by the output end of the second drive device 241. When the output end of the second drive device 241 moves to the lowest end, the output end of the second drive device 241 is lower than the lowest end of the support member 300, and the output end of the second drive device 241 cannot intercept the support member 300.

[0028] Furthermore, the second drive device 241 is a cylinder.

[0029] Furthermore, the guide portion 250 includes a guide sleeve 251 and a guide post 252. The guide sleeve 251 is fixedly connected to the end face of the third plate-shaped portion 280 facing the conveying mechanism 100, and the guide post 252 is fixedly connected to the end face of the first plate-shaped portion 220 facing the third plate-shaped portion 280. The guide sleeve 251 is sleeved on the outer periphery of the guide post 252. In the embodiments provided in this application, there are four guide portions 250, and the four guide portions are symmetrically distributed at the four corners of the first plate-shaped portion 220.

[0030] Furthermore, the guide portion 250 can also be a telescopic slide rail with telescopic function.

[0031] A first positioning part 210 is provided on the first plate-shaped part 220. The first positioning part 210 can be fixedly engaged with the second positioning part 310 provided on the carrier 300, so that the carrier 300 and the first plate-shaped part 220 are positioned at the upper limit in the operating direction of the conveying mechanism 100.

[0032] Furthermore, the second positioning part 310 is a positioning hole of a circle, square or other shape, and the first positioning part 210 is a positioning pin of a circle, square or matching shape of a protrusion, protrusion or other shape. The first positioning part 210 can be inserted into the second positioning part 310 to achieve the positioning function.

[0033] A signal reading and writing module 230 is provided on the first plate-shaped part 220. The signal reading and writing module 230 can sense the signal tag 330 provided on the carrier 300, read the existing process information in the signal tag 330 provided on the carrier 300, and write the information of the current processing process into the signal tag 330.

[0034] The location of the signal reading and writing module 230 is not limited in this application, as long as it can realize the sensing, reading and writing of the signal tag 330. For example, the signal reading and writing module 230 can be set on the side of the first plate-shaped part 220 or on the limiting part 270. Correspondingly, the carrier 300 is provided with the signal tag 330 so that the signal reading and writing module 230 can sense the signal tag 330. To achieve miniaturization of the lifting mechanism 200, this application provides an installation method as follows: a groove 221 is formed on the first plate-shaped portion 220, and a signal reading / writing module 230 is disposed in the groove 221. The bottom of the support member 300 is provided with a second plate-shaped portion 320, the extension direction of the second plate-shaped portion 320 is parallel to the operating direction of the conveying mechanism 100, and the signal tag 330 is located on the side of the second plate-shaped portion 320 facing the first plate-shaped portion 220. When the support member 300 is intercepted by the output end of the second driving device 241, the signal tag 330 can face the signal reading / writing module 230. This arrangement can make full use of the space above the lifting mechanism 200, thereby miniaturizing the mold.

[0035] Furthermore, the signal reading and writing module 230 is an RFID antenna, and the signal tag 330 is a chip.

[0036] Reference Figure 4 and Figure 5 The carrier 300 includes a second plate-shaped portion 320 and a receiving portion 350, the receiving portion 350 being used to hold the product to be processed. The extending direction of the second plate-shaped portion 320 is parallel to the operating direction of the conveying mechanism 100. A second positioning portion 310 is provided on the second plate-shaped portion 320, the second positioning portion 310 being able to be fixedly engaged with a first positioning portion 210 provided on the lifting mechanism 200, so that the carrier 300 and the first plate-shaped portion 220 are positioned at the upper limit in the operating direction of the conveying mechanism 100.

[0037] A signal tag 330 is provided on the carrier 300. As mentioned above, the position of the signal tag 330 is not limited in this application, as long as it can realize the sensing and data transmission with the signal reading and writing module 230. In order to achieve miniaturization of the lifting mechanism 200, this application provides a setting method as follows: the signal tag 330 is located on the side of the second plate-shaped part 320 facing the first plate-shaped part 220. When the carrier 300 is intercepted by the output end of the second driving device 241, the signal tag 330 can face the signal reading and writing module 230. This setting method can make full use of the space above the lifting mechanism 200, so as to miniaturize the mold.

[0038] The second plate-shaped portion 320 is provided with a sensing portion 360 on the side opposite to the conveying mechanism 100. When the sensor 400 senses the sensing portion 360, the sensor 400 can send the sensing information to the central controller, which then controls the lifting and retraction of the first drive device 260 and the second drive device 241.

[0039] The carrier 30 is provided with a second stop part 340. When the output end of the second drive device 241 moves to the highest position near the carrier 300, the upper end of the output end of the second drive device 241 is higher than the lowest end of the second stop part 340. The second stop part 340 of the carrier 300 abuts against the output end of the second drive device 241. At this time, the carrier 300 is blocked by the output end of the second drive device 241 and cannot continue to move along the conveying direction of the conveying mechanism 100.

[0040] The operating process of the transport mechanism provided in this application is as follows:

[0041] The carrier 300 moves along the transmission direction of the conveying mechanism 100. When the sensor 400 senses the sensing part 360, it sends the sensing information to the central controller, which then controls the second drive device 241 to lift. When the output end of the second drive device 241 moves to the highest position near the carrier 300, the upper end of the output end of the second drive device 241 is higher than the lowest end of the second stop part 340. The second stop part 340 of the carrier 300 abuts against the output end of the second drive device 241. At this time, the carrier 300 is blocked by the output end of the second drive device 241 and cannot continue to move along the transmission direction of the conveying mechanism 100.

[0042] Furthermore, the central controller controls the first drive device 260 to lift in a direction perpendicular to the conveying mechanism 100. Under the action of the first drive device 260, the guide post 252 of the guide part 250 extends the guide sleeve 251 in the direction of movement of the first drive device 260, so that the first plate-shaped part 220 moves in a direction perpendicular to the conveying mechanism 100, thereby causing the carrier 300 to move in a direction perpendicular to the conveying mechanism 100 and disengage from the conveying mechanism 100.

[0043] Furthermore, during the movement of the carrier 300 away from the conveying mechanism 100, the first positioning part 210 provided on the first plate-shaped part 220 passes through the second positioning part 310 provided on the second plate-shaped part 320, thereby achieving the positioning of the carrier 300 and the cooperation and fixation between the lifting mechanism 200 and the carrier 300, preventing the carrier 300 from shifting or slipping during movement, and ensuring the stability of the carrier 300 during the lifting process. The position of the limiting part 271 is the highest position that the carrier 300 can reach. When the second plate-shaped part 320 of the carrier 300 abuts against the limiting part 271, the carrier 300 cannot continue to move in the direction perpendicular to the conveying mechanism 100, further ensuring the stability and reliability of the carrier 300 during the processing.

[0044] Meanwhile, as the carrier 300 moves away from the conveyor 100 in a direction perpendicular to the conveyor 100, the signal reading and writing module 230 on the lifting mechanism 200 can sense the signal tag 330 set on the carrier 300 and read the data recorded on the signal tag 330 to realize the first data transmission. The first data transmission reads the process information that the carrier 300 has already gone through.

[0045] During the above process, the stopping, lifting, positioning, and data transmission of the carrier 300 occur almost simultaneously. Because the stopping, lifting, positioning, and data transmission are carried out at the same time, the production line cycle time is shortened.

[0046] After the carrier 300 is processed in the current process, the first driving device 260 descends in a direction perpendicular to the conveying mechanism 100, and the guide post 252 of the guide part 250 retracts the guide sleeve 251 in the direction of movement of the first driving device 260, so that the carrier 300 descends in a direction perpendicular to the conveying mechanism 100 and falls back onto the conveying mechanism 100.

[0047] Meanwhile, as the carrier 300 falls back to the conveyor 100 along a direction perpendicular to the conveyor 100, the signal reading and writing module 230 on the lifting mechanism 200 can sense the signal tag 330 set on the carrier 300 and perform a second data transmission. The second data transmission writes the processing information of the current process into the signal tag 330.

[0048] Simultaneously, the second drive device 241 descends. When the output end of the second drive device 241 reaches its lowest point, the output end of the second drive device 241 is lower than the lowest point of the carrier 300. The output end of the second drive device 241 stops intercepting the carrier 300, and the carrier 300 continues to move along the moving direction of the conveying mechanism 100.

[0049] After the carrier 300 flows away, the sensor 400 will lose its sensing function and immediately reset, preparing to intercept the next carrier.

[0050] This application provides a water pump assembly device, which includes a workbench 10, an assembly mechanism 20, and a transport mechanism as described in this application. The assembly mechanism 20 includes a plurality of assembly stations 201. The transport mechanism is fixedly mounted on the workbench 10, and the assembly mechanism 20 is located directly above the transport mechanism.

[0051] The receiving portion 350 of the carrier 300 is used to carry the water pump to be assembled, and the signal tag 330 records the process information that the water pump to be assembled has undergone.

[0052] The conveying mechanism 100 can drive the carrier 300 to move along the conveying direction of the conveying mechanism 100. When the sensor 400 senses the sensing part 360, the sensor 400 transmits the sensing information to the central controller. The central controller controls the output end of the second drive device 241 to move to the highest point along the operating direction perpendicular to the conveying mechanism 100. At this time, the carrier 300 continues to move along the conveying direction of the conveying mechanism 100 until the first stop part 240 abuts against the second stop part 340, so that the carrier 300 stops moving along the conveying direction of the conveying mechanism 100.

[0053] Simultaneously, the central controller controls the output end of the first drive device 260 to move along a direction perpendicular to the operating direction of the conveying mechanism 100, causing the carrier 300 to detach from the conveying mechanism 100. Furthermore, the first positioning part 210 on the first plate-shaped part 220 passes through the second positioning part 310 on the second plate-shaped part 320, thereby limiting the carrier 300 and the first plate-shaped part 220 in the operating direction of the conveying mechanism 100, preventing the carrier 300 from detaching or slipping during movement, and ensuring the carrier 300 remains stable. The signal reading / writing module 230 reads the information recorded on the signal tag 330 regarding the previous assembly process of the water pump to be assembled.

[0054] When the output end of the first drive device 260 pushes the carrier 100 to abut the limiting part 271, the carrier 300 stops moving. At this time, the water pump to be assembled has arrived at the assembly station located directly above the lifting mechanism 200 and is being processed in this step.

[0055] After the assembly process is completed, the signal reading and writing module 230 writes the processing process information into the signal tag 330, and the output end of the first driving device 260 moves along the operating direction perpendicular to the conveying mechanism 100, so that the carrier 300 falls back into the conveying mechanism 100, and the output end of the second driving device 241 moves to the lowest end along the operating direction perpendicular to the conveying mechanism 100, so that the carrier 300 is no longer blocked and can continue to move along the conveying direction of the conveying mechanism 100.

[0056] After the carrier 300 flows away, the sensor 400 will lose its sensing function and immediately reset, preparing to intercept the next carrier.

[0057] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.

The second stop part (340) abuts against the output end of the second driving device (241), causing the carrier (300) to stop moving along the conveying direction of the conveying mechanism (100). At the same time, the output end of the first driving device (260) moves along the operating direction perpendicular to the conveying mechanism (100), causing the carrier (300) to disengage from the conveying mechanism (100). The first positioning part (210) provided on the first plate-shaped part (220) passes through the second plate-shaped part (360). The second positioning part (310) is provided on the 20), and the signal reading and writing module (230) reads the information of the previous assembly process recorded on the signal tag (330). When the carrier (300) abuts the limiting part (271), the carrier (300) enters the processing station located directly above the lifting mechanism (200). When the current processing process is completed, the signal reading and writing module (230) writes the current processing process information into the signal tag (330), and the output end of the first driving device (260) moves along the operating direction perpendicular to the conveying mechanism (100), so that the carrier (300) falls back into the conveying mechanism (100), and the output end of the second driving device (241) moves to the lowest end along the operating direction perpendicular to the conveying mechanism (100), so that the carrier (300) loses the obstruction and can continue to move along the conveying direction of the conveying mechanism (100).
