Description
Technical Field
[0001] This invention relates to the field of automation technology, and in particular to a multi-station synchronous assembly device. Background Technology
[0002] With the continuous growth of production demand, production processes are also being improved. In automated assembly processes, the parts to be assembled are usually processed separately first, and then placed on an assembly machine or press machine for assembly. During assembly, the parts to be assembled or press-fitted need to be placed on different positioning seats in advance, and then the machine is started for press-fitting.
[0003] For example, publication number "CN202028904U" discloses "a bushing pressing device for a large-angle swing arm," which includes two sets of bushing pressing units located on the outer sides of both ends of a large-angle swing arm on the worktable surface. Each bushing pressing unit includes a bushing positioning rod pushed by external force. A bushing to be pressed is fitted outside the bushing positioning rod. A guide rod is fitted outside the bushing positioning rod with the bushing, and a guide sleeve bracket is fitted outside the guide rod. Both the bushing positioning rod and the guide rod are coaxial with the swing arm. A hollow bushing positioning module, coaxial with the swing arm and used for pressing the bushing, is located in front of the bushing positioning rod in the pushing direction. However, in practical applications, since each component needs to be pre-processed before pressing and then placed on the pressing device, the placement direction may change. Each time, repositioning and adjustment of the direction are required. As the number of components increases, different robotic arms are needed, resulting in reduced production efficiency and increased production costs. Furthermore, the product needs to be repositioned during transfer, which can easily lead to errors. Summary of the Invention
[0004] In view of the problems of low production efficiency, high production cost and easy error in the existing technology mentioned in the background, the present invention provides a multi-station synchronous assembly device, which can avoid positioning errors when products are transferred between various components, unify the positioning standards for product placement between various components, strengthen the connection between various components, make the product transport between components smoother, and enable the unified transport of various parts, thereby reducing production costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution.
[0006] A multi-station synchronous assembly device includes the following components: a pre-assembly transfer component: receiving and processing products; a rotating assembly component: positioned next to the pre-assembly transfer component, rotating and assembling the products processed by the pre-assembly transfer component; a feeding component: conveying the products assembled by the rotating assembly component; and a synchronous transfer gripper: simultaneously gripping and transferring products from the pre-assembly transfer component and the rotating assembly component, placing the processed products on the rotating assembly component, and placing the assembled products on the feeding component. In this invention, a pre-assembled transfer assembly, a rotating assembly, and a feeding assembly are combined together, with the rotating assembly positioned between the other two. This rotating assembly is responsible for assembling the pre-processed components from the pre-assembled transfer assembly. The pre-processing of each component typically involves a series of operations on its assembly surfaces, such as installing bearings, pressing in buffer components, painting, and applying oil. To facilitate the transfer of components between processing stations, they are all oriented in one direction for ease of processing, and the processed surfaces are generally facing upwards. These processed surfaces also typically serve as assembly surfaces during the assembly process. During component assembly, the assembly surfaces of each component face relative to each other, and the components are assembled together or onto the product body via a snap-fit structure. The rotating assembly in this invention can rotate the orientation of each component, ensuring that the initial orientation of each component on the rotating assembly aligns with the pre-assembled transfer assembly. Since the pre-assembled transfer components are identical, they can be directly transferred to the rotating assembly using a synchronous transfer gripper. This avoids multiple turning and positioning operations when switching products between two components, improving positioning accuracy. The same installation positioning standard applies between the two components, and only one robotic arm is needed to complete the transfer, saving production costs. Furthermore, the positioning standard on the feeding component is the same as that on the pre-assembled transfer components and the rotating assembly. Therefore, two robotic grippers are installed on the synchronous transfer gripper to simultaneously grip the various parts on the pre-assembled transfer components and the finished products on the rotating assembly, performing synchronous lateral movement. Because the positioning standards of the three components are identical, the synchronous transfer of parts and finished products from different components can be achieved in a single gripping and moving action, improving product conveying efficiency. Moreover, only one positioning operation is needed to complete the transfer of multiple parts and finished products, improving production precision.
[0007] Preferably, the pre-assembled transfer assembly is equipped with a transfer platform, and the pre-assembled transfer assembly includes a transfer station. The rotating assembly is equipped with a mounting base, and the mounting base faces the same direction as the transfer platform. By aligning the transfer platform on the transfer station with the mounting base and ensuring that they face the same direction, the synchronous transfer gripper can directly move each processed product from the pre-assembled transfer assembly to the rotating assembly, where it is then rotated and assembled internally. This avoids errors caused by secondary positioning and installation, thus improving efficiency.
[0008] Preferably, the mounting base includes a finished product base and a reversing base, and the transfer table includes a main body base and a part base. The main body base is configured to correspond to the finished product base, and the part base is configured to correspond to the reversing base. The product assembly process generally includes the product body and various components to be assembled. Therefore, the mounting base includes a fixed finished product base and a movable reversing base. The reversing base can rotate via gear transmission or motor transmission. Components to be pressed into the product body are placed on the reversing base. The reversing base corresponds to the part base on the transfer table, while the finished product base corresponds to the main body base. This one-to-one correspondence ensures that the positions of each component and the product body are standardized during pre-assembly and transfer component loading, improving the accuracy of the product during transfer.
[0009] Preferably, the synchronous transfer gripper includes a multi-part gripper and a finished product gripper. The multi-part gripper grips the main body and part seats, while the finished product gripper grips the finished product seats. The multi-part gripper grips the various components and the product body placed on the pre-assembled transfer assembly, while the finished product gripper grips the finished product that has been assembled on the rotating assembly. The gripping actions of the two multi-part grippers and the finished product gripper are synchronized, simultaneously completing the product transfer between the pre-assembled transfer assembly and the rotating assembly, and between the rotating assembly and the feeding assembly, thereby improving transfer efficiency and increasing production cycle time.
[0010] Preferably, the rotating assembly includes a support frame, the reversing seat is rotatably connected to the support frame, and a rotation drive is connected to the support frame. The rotation drive drives the reversing seat to rotate. The reversing seat can be connected to a driven device such as a gear or pulley. The reversing action is performed by driving the rotation drive. The rotation drive includes, but is not limited to, a motor pulley assembly and a cylinder gear assembly.
[0011] Preferably, the rotating assembly includes a base, a support frame slidably connected to the base, an assembly pusher provided on the base, the assembly pusher connected to the support frame, a synchronous rack provided on the support frame, and a synchronous gear rotatably connected to the base, the synchronous gear meshing with the synchronous rack. Since the reversing seat only serves a reversing function, and there is a reversing gap between the reversing seat and the finished product seat to avoid interference, it is necessary to use an assembly pusher to push the entire support frame to bring the reversing seat closer to the finished product seat and press the components on the reversing seat into the finished product seat. There are usually multiple components that need to be pressed. By meshing all the synchronous racks on the same synchronous gear, mutual restraint can be generated during the sliding of each support frame to ensure synchronous movement. When the product body is subjected to pressing force, it can be balanced in all directions to avoid product tilting or squeezing between the product body and the finished product seat due to different strokes of the components during the pressing process. The reversing assembly is equipped with a synchronizing element, which includes, but is not limited to, the aforementioned gear set or pulley transmission set, to achieve the limiting constraint between each support frame.
[0012] Preferably, the pre-assembled transfer assembly includes a pressing station, and an oiling station is connected to the pressing station along the transfer direction. When it is necessary to oil the pressed parts on the product, the pressing station first presses the pressed parts onto the product, and then the oiling station directly applies oil to the pressed parts on the product, thereby avoiding situations such as difficulty in gripping or oil dripping caused by pre-oiling the pressed parts.
[0013] Preferably, the pre-assembled transfer assembly includes a loading and scanning station. The product is placed on the pre-assembled transfer assembly via the loading and scanning station, and the placement is confirmed by camera scanning. Once confirmed to be correct, the product is then transported to the next station.
[0014] Preferably, the pre-assembled transfer assembly includes several processing stations, with a rotary table between each processing station, and a transfer table mounted on the rotary table. The pre-assembled transfer assembly can have multiple processing stations according to production needs, and the products are transferred via the transfer table on the rotary table. This saves space occupied by the pre-assembled transfer assembly and allows the transfer table to return directly to the loading and scanning station after passing through the transfer station, improving production efficiency.
[0015] Preferably, the rotating assembly is provided with a shell pressing station. The shell pressing station on the rotating assembly can press the shell onto the assembled product, thereby preventing the assembled parts from detaching during the transfer process of the synchronous transfer gripper.
[0016] The beneficial effects of this invention are as follows:
[0017] (1) The rotating assembly can be rotated and pressed. The initial orientation of the transfer table and the mounting base is the same. The synchronous transfer gripper simultaneously grabs the pre-assembled transfer components and the products on the rotating assembly for lateral movement. The transfer efficiency is high, the positioning standard is uniform, and the cost is saved.
[0018] (2) By rotating the assembly, parts that are placed in the same direction can be rotated to different directions for assembly, avoiding the error caused by reversing the placement;
[0019] (3) By connecting the synchronous components of each support frame, the synchronous movement between each support frame is ensured, so that the product body can achieve force balance during the assembly of parts and avoid squeezing. Attached Figure Description

Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] Example 1:
[0031] like Figure 1 , 2 As shown, a multi-station synchronous assembly device includes the following components: a pre-assembly transfer component 1: receiving and processing products; a rotating assembly component 2: positioned next to the pre-assembly transfer component 1, rotating and assembling the products processed by the pre-assembly transfer component 1; a feeding component 3: conveying the products assembled by the rotating assembly component 2; and a synchronous transfer gripper 4: simultaneously gripping and transferring products from the pre-assembly transfer component 1 and the rotating assembly component 2, placing the processed products on the rotating assembly component 2, and placing the assembled products on the feeding component 3.
[0032] In this invention, the pre-assembled transfer assembly 1, the rotating assembly 2, and the feeding assembly 3 are combined together. The rotating assembly 2 is located between the other two and is responsible for assembling the pre-processed parts on the pre-assembled transfer assembly 1. The pre-processing of each part generally involves a series of operations on the assembly surfaces of the parts, such as pressing in cushioning components, painting, and applying oil. To facilitate the transfer of the parts between the processing stations 101, they are all oriented in the same direction for easy processing, and the processing surfaces are generally set upwards. These processing surfaces are also generally used as assembly surfaces during the assembly process. During the assembly of the parts, the assembly surfaces of each part will face relative to each other. The parts are assembled together or assembled onto the product body through a snap-fit structure. The rotating assembly 2 in this invention can rotate the orientation of each part, so that the initial orientation of each part on the rotating assembly 2 can be aligned with the pre-assembled transfer assembly 1. Since component 1 is identical, the pre-assembled transfer component 1 can be directly transferred to the rotating assembly 2 via the synchronous transfer gripper 4. This avoids multiple turning and positioning operations when switching products between the two components, improving positioning accuracy. The installation positioning standard between the two components is the same, and only one robotic arm is needed to complete the transfer, saving production costs. Furthermore, the positioning standard on the feeding component 3 is the same as that on the pre-assembled transfer component 1 and the rotating assembly 2. Therefore, two robotic grippers are set on the synchronous transfer gripper 4 to grip the various parts on the pre-assembled transfer component 1 while simultaneously gripping the finished product on the rotating assembly 2, performing synchronous lateral movement. Because the positioning standards of the three components are the same, the synchronous transfer of parts and finished products on different components can be achieved in a single gripping and moving action, improving product conveying efficiency. Moreover, only one positioning operation is needed to complete the transfer of multiple parts and finished products, improving production accuracy.
[0033] like Figure 2 ,3 As shown, the pre-assembled transfer assembly 1 is provided with a transfer table 6. The pre-assembled transfer assembly 1 includes a transfer station 14. The rotating assembly 2 is provided with a mounting base 21. The mounting base 21 faces the same direction as the transfer table 6. The mounting base 21 includes a finished product base 211 and a reversing base 212. The transfer table 6 includes a body base 61 and a part base 62. The body base 61 is set corresponding to the finished product base 211, and the part base 62 is set corresponding to the reversing base 212.
[0034] By aligning the transfer table 6 on the transfer station 14 with the mounting base 21 and ensuring they face the same direction, the synchronous transfer gripper 4 can directly move each processed product from the pre-assembled transfer assembly 1 to the rotating assembly 2. The rotating assembly 2 then performs internal rotational assembly, avoiding errors caused by secondary positioning and improving efficiency. The product assembly process typically includes the product body and various components to be assembled. Therefore, the mounting base 21 includes a fixed finished product base 211 and a movable reversing base 212. The reversing base 212 can rotate via gear or motor transmission. Components to be pressed into the product body are placed on the reversing base 212. The reversing base 212 corresponds to the component base 62 on the transfer table 6, while the finished product base 211 corresponds to the body base 61. This one-to-one correspondence ensures that the positions of each component and the product body are standardized during the pre-assembled transfer assembly 1 loading process, improving the accuracy of the product during transfer.
[0035] like Figure 1 , 4 As shown, the synchronous transfer gripper 4 includes a multi-part gripper 41 and a finished product gripper 42. The multi-part gripper 41 grips the main body seat 61 and the part seat 62, while the finished product gripper 42 grips the finished product seat 211. The multi-part gripper 41 grips the various parts and the product body placed on the pre-assembled transfer assembly 1, while the finished product gripper 42 grips the finished product that has been assembled on the rotating assembly 2. The gripping actions of the two multi-part grippers 41 and the finished product gripper 42 are synchronized, simultaneously completing the product transfer between the pre-assembled transfer assembly 1 and the rotating assembly 2, and between the rotating assembly 2 and the feeding assembly 3, thereby improving transfer efficiency and increasing production cycle time.
[0036] like Figure 5As shown, the rotating assembly 2 includes a support frame 22, a reversing seat 212 rotatably connected to the support frame 22, and a rotation drive 23 connected to the support frame 22. The rotating assembly 2 also includes a base 24, with both support frames 22 slidably connected to the base 24. An assembly pusher 25 is provided on the base 24 and connected to the support frame 22. The rotation drive 23 drives the reversing seat 212 to rotate. A driven device such as a gear or pulley can be connected to the reversing seat 212, and the reversing is achieved by the rotation drive 23. The action involves rotating the drive component 23, which is a cylinder gear set, including a push cylinder 231, a push rack 232 connected to the push cylinder, and a driven gear 233 connected to the reversing seat. The push rack meshes with the driven gear. Since the reversing seat 212 can only perform the reversing function, and there is a reversing gap between the reversing seat 212 and the finished seat 211 to avoid interference, it is necessary to assemble the push component 25 to push the entire support frame 22 to move the reversing seat 212 closer to the finished seat 211 and press the components on the reversing seat 212 into the finished seat 211.
[0037] like Figure 6 As shown, the pre-assembled transfer assembly 1 includes a processing station 101, a rotary table 102 is provided between each processing station 101, a transfer table 6 is provided on the rotary table 102, the processing station 101 includes a pressing station 12, the pressing station 12 is connected to an oiling station 13 along the transfer direction, and the processing station 101 includes a material loading and scanning station 11. When it is necessary to apply oil to the press-fit parts on the product, the press-fit parts are first pressed onto the product through the press-fit station 12, and then the oiling station 13 applies oil directly to the product through the press-fit parts. This avoids problems such as difficulty in gripping and oil dripping caused by pre-applying oil to the press-fit parts. The product is placed on the pre-assembled transfer assembly 1 through the loading and scanning station 11, and the placement is confirmed by camera scanning. After confirmation, the product is transported to the subsequent station. The pre-assembled transfer assembly 1 can be equipped with multiple processing stations 101 according to production needs, and the product is transferred through the transfer table 6 set on the rotary table 102. This saves the area occupied by the pre-assembled transfer assembly 1 and allows the transfer table 6 to return directly to the loading and scanning station 11 after passing through the transfer station 14, thereby improving production efficiency.
[0038] like Figure 7 As shown, the rotating assembly 2 is provided with a shell pressing station 5. The shell pressing station 5 provided on the rotating assembly 2 can press the shell of the assembled product, thereby preventing the assembled parts from falling off during the transfer process of the synchronous transfer gripper 4.
[0039] The assembly and operation process of the multi-station synchronous assembly device in this embodiment is as follows: In this embodiment, the pre-assembly transfer component 1 includes a material loading and scanning station 11, a pressing station 12, an oiling station 13, and a transfer station 14. Each station is arranged around the rotary table 102. A rotating assembly 2 is arranged at the corresponding position of the transfer station 14. A shell pressing station 5 is arranged above the rotating assembly 2. The shell pressing station 5 is arranged directly opposite the finished product seat 211. A feeding component 3 is arranged on the other side of the rotating assembly 2. A synchronous transfer gripper 4 is installed above component 3, rotating assembly 2, and transfer station 14. The synchronous transfer gripper 4 includes a multi-part gripper 41 and a finished product gripper 42. During operation, the product is divided into multiple pieces and loaded at the loading and scanning station 11, placed on the main body seat 61 and the part seat 62 respectively. The rotary table 102 rotates and moves the product to the pressing station 12. The pressing mechanism on the pressing station 12 presses the part into place, and then it is transferred to the oiling station 13 for oiling. When the product arrives at the transfer station 14, the multi-part gripper 41 simultaneously grips the product on both the main body seat 61 and the part seat 62. Meanwhile, the finished product gripper 42 grips the finished product on the finished product seat 211 of the rotating assembly 2 and moves it laterally toward the feeding assembly 3. Then, the multi-part gripper 41 moves above the rotating assembly 2, and the finished product gripper 42 moves above the feeding assembly 3. At this point, the reversing seat 212 and the finished product seat 211 are positioned and oriented the same as the transfer table 6. The multi-part gripper 41 then places the various dispersed products... On the mounting base 21, the finished product gripper 42 places the assembled finished product on the feeding assembly 3 and transports it out. Then, the rotation drive 23 in the rotating assembly 2 drives the reversing seat 212 to rotate. After each reversing seat 212 is aligned with the finished product seat 211 in the middle, the assembly pusher 25 pushes the support frame 22 to press the parts on the reversing seat 212 into the product body. After the pressurization is completed, the outer shell pressing station 5 presses down the outer shell to complete the product assembly. Then, the synchronous transfer gripper 4 repeats the above operation to start the cycle operation.
[0040] Example 2:
[0041] like Figure 8 As shown, unlike Embodiment 1, in this embodiment, each support frame 22 is provided with a synchronous rack 26, and a synchronous gear 27 is rotatably connected to the base 24. The synchronous gear 27 meshes with the synchronous rack 26. Since there are generally multiple components that need to be press-fitted, meshing all the synchronous racks 26 with the same synchronous gear 27 can mutually restrict each other during the sliding process of each support frame 22, ensuring synchronized movement. When the product body is subjected to pressing force, it can be balanced in all directions, preventing the product body from tilting or being squeezed between it and the finished product base 211 due to different stroke lengths of the components during the pressing process.
