Description

Technical Field

[0001] This invention belongs to the field of workpiece assembly technology, and particularly relates to a modular pre-assembly device. Background Technology

[0002] Currently, some sub-workpieces need to be placed in a specific support fixture before being loaded into the loading cavity of the mother workpiece. This is to prevent the sub-workpieces from being unlocked. After aligning the support fixture with the loading cavity of the mother workpiece, the sub-workpieces are pushed into the loading cavity from the support fixture. At the same time, each loading cavity of the mother workpiece needs to be filled with at least two sub-workpieces, and a connecting seat needs to be placed between the at least two sub-workpieces. The connecting seat separates the sub-workpieces and docks with each of the sub-workpieces.

[0003] In existing technologies, sub-workpieces and connecting seats are usually loaded into the loading cavity one by one. After the connecting seat is loaded into the loading cavity, it is necessary to hold the connecting seat with your hand until the last sub-workpiece is loaded into the loading cavity before you can let go. This results in high labor intensity and low assembly efficiency in the entire loading process. Summary of the Invention

[0004] To address the aforementioned defects or shortcomings, this invention provides a modular pre-assembly device, aiming to solve the technical problem of high labor intensity and low assembly efficiency caused by loading sub-workpieces and connecting seats into the loading cavity using a single loading method.

[0005] To achieve the above objectives, the present invention provides a modular pre-assembly device, wherein the modular pre-assembly device includes a modular fixture, a clamping mechanism, and at least two pushing mechanisms; at least two first pushing ports are sequentially spaced on the periphery of the modular fixture, and a second pushing port is formed on the modular fixture, the second pushing port being used for the connecting seat to enter the modular fixture; the clamping mechanism is used to extend into or retract into the modular fixture and to clamp or release the connecting seat when extended into the modular fixture; the at least two pushing mechanisms correspond one-to-one with the at least two first pushing ports and are both used to push the sub-workpiece in the carrying fixture into the modular fixture.

[0006] In one embodiment of the present invention, the second push port is located on the lower or upper side of the module fixture, and the clamping mechanism is configured to extend into or out of the module fixture from the second push port.

[0007] In one embodiment of the present invention, the second push port is located on the lower side of the module fixture, and the clamping mechanism includes a clamping drive and a gripper body. The gripper body extends upward from the upper end of the clamping drive. The clamping drive is used to drive the gripper body to clamp or release the connecting seat. The gripper body is used to extend into the module fixture from the second push port when the connecting seat is clamped.

[0008] In one embodiment of the present invention, the modular pre-assembly device further includes a support component, which is disposed on the upper side of the clamping drive member and has an opening for the clamping claw to pass through. The support component is configured as an upward support module fixture.

[0009] In one embodiment of the present invention, the support assembly includes a support plate and a support frame. The support plate is configured as an upward support module fixture and has an opening. The support frame includes a lower support frame and an upper support rod arranged sequentially from bottom to top. The lower support frame is erected on the outside of the clamping drive member and supports the support plate upward on the upper side of the clamping drive member. The upper support rod is connected to the lower support frame and extends upward from the opening. The upper end of the upper support rod is configured as a support connecting seat.

[0010] In one embodiment of the present invention, the lower support frame includes radial support rods and axial support rods, and the number of radial support rods and axial support rods is set to at least two. The at least two radial support rods extend from the same center point in different radial directions, and the at least two radial support rods are placed on the upper side of the clamping drive member and are set as an upward support plate. The upper ends of the at least two axial support rods are respectively connected to the ends of the at least two radial support rods away from the center point. The at least two axial support rods are arranged sequentially at intervals around the periphery of the clamping drive member, and the upper support rod is located at the center point.

[0011] In one embodiment of the present invention, the number of gripper bodies is at least two, and the at least two gripper bodies are arranged sequentially at intervals along the circumference of the gripping drive member.

[0012] In one embodiment of the present invention, the modular fixture is square in shape and includes a top plate, a bottom plate, a first side plate, a second side plate, a first vertical beam, and a second vertical beam. The top plate and the bottom plate are arranged vertically and alternately. The first side plate and the second side plate are respectively arranged on the first side and the second side of the modular fixture, which are spaced apart from each other, and are both connected to the top plate and the bottom plate. The first vertical beam connects the top plate and the bottom plate at the corner positions of the first side and the third side of the modular fixture. The first vertical beam is spaced apart from the first side plate to form a first push opening on the first side. The second vertical beam connects the top plate and the bottom plate at the corner positions of the second side and the third side of the modular fixture. The second vertical beam is spaced apart from the second side plate to form a first push opening on the second side. The modular fixture is open on both the third side and the fourth side.

[0013] In one embodiment of the present invention, a limiting plate is provided on the base plate. The limiting plate is located near the third side, and the side of the limiting plate facing the first side and the second side is respectively provided as a limiting contour edge. The limiting contour edge is used to fit against the periphery of the sub-workpiece.

[0014] In one embodiment of the present invention, the pushing mechanism includes a mounting base, a pushing drive, and a pushing head. The mounting base is fixedly disposed, and the pushing drive is disposed on the mounting base and drivenly connected to the pushing head. The pushing drive is used to drive the pushing head to push the sub-workpiece in the carrying fixture into the module fixture.

[0015] In one embodiment of the present invention, a pusher head is formed with a pusher contour surface that conforms to the periphery of the sub-workpiece.

[0016] Through the above technical solution, the modular pre-assembly device provided by the present invention has the following beneficial effects: When using the aforementioned modular pre-assembly device, the device includes a modular fixture, a clamping mechanism, and at least two pushing mechanisms. A second pushing port is formed on the lower or upper side of the modular fixture, allowing the connecting seat to enter and exit the fixture. The clamping mechanism extends into or exits the modular fixture and, when extended into the fixture, clamps or releases the connecting seat within it. Simultaneously, at least two first pushing ports are sequentially spaced along the periphery of the modular fixture. Each of the at least two pushing mechanisms corresponds to one of the at least two first pushing ports and is used to push the sub-workpiece within the carrying fixture into the modular fixture, thereby allowing the connecting seat to... The workpieces can be pre-clamped and positioned in the modular fixture by the clamping mechanism. Then, each pushing mechanism can simultaneously or sequentially push the corresponding sub-workpieces into the modular fixture from each first pushing port. After all the sub-workpieces abut against the connecting seat and complete the docking, the clamping mechanism releases the connecting seat and exits the modular fixture. At this point, all the sub-workpieces and connecting seats can be pre-assembled in the modular fixture. When the modular fixture is subsequently transferred to the loading cavity of the mother workpiece for docking, all the sub-workpieces and connecting seats can be pushed into the loading cavity at once, avoiding the use of individual loading and eliminating the need for manual operation of the connecting seat. This effectively reduces labor intensity and improves assembly efficiency.

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] like Figure 1 and Figure 2 As shown, a number of filling cavities 801 are sequentially spaced around the circumference of the mother workpiece 800, and the inner ring of each filling cavity 801 needs to be filled with one sub-workpiece 500. After the filling of the sub-workpiece 500 in the inner ring is completed, the connecting seat 700 needs to be filled before the filling of the sub-workpiece 500 in the outer ring can be completed. The outer ring of each filling cavity 801 needs to be filled with two sub-workpieces 500.

[0022] The modular pre-assembly device of the present invention will now be described with reference to the accompanying drawings.

[0023] like Figure 3 and Figure 4 As shown, the present invention provides a modular pre-assembly device, wherein the modular pre-assembly device includes: The module fixture 100 has at least two first push ports 101 formed at intervals on its periphery, and a second push port 102 is formed on the module fixture 100. The second push port 102 is used to allow the connector 700 to enter the module fixture 100. The clamping mechanism 200 is used to extend into or out of the module fixture 100 and to clamp or release the connecting seat 700 when it is extended into the module fixture 100. At least two pushing mechanisms 300 are respectively associated with at least two first pushing ports 101 and are used to push the sub-workpieces 500 in the carrying fixture 600 into the module fixture 100.

[0024] When using the above-mentioned modular pre-assembly device, the modular pre-assembly device includes a modular fixture 100, a clamping mechanism 200, and at least two pushing mechanisms. The modular fixture 100 has a second pushing port 102 for allowing the connecting seat 700 to enter the modular fixture 100. The clamping mechanism 200 is used to extend into or out of the modular fixture 100 and, when extended into the modular fixture 100, clamps or releases the connecting seat 700 within the modular fixture 100. Simultaneously, at least two first pushing ports 101 are sequentially spaced along the periphery of the modular fixture 100. At least two pushing mechanisms 300 correspond one-to-one with each of the at least two first pushing ports 101 and are both used to push the sub-workpiece 500 within the carrying fixture 600 into the modular fixture 100, thereby allowing the connecting seat 700 to... The sub-workpieces 500 can be pre-clamped and positioned in the modular fixture 100 by the clamping mechanism 200. Then, each pushing mechanism 300 can simultaneously or sequentially push the corresponding sub-workpieces 500 into the modular fixture 100 from each first pushing port 101. After all the sub-workpieces 500 abut against the connecting seat 700 and complete the docking, the clamping mechanism 200 releases the connecting seat 700 and exits the modular fixture 100. At this point, all the sub-workpieces 500 and the connecting seat 700 can be modularly pre-assembled in the modular fixture 100. When the modular fixture 100 is subsequently transferred to dock with the loading cavity of the mother workpiece, all the sub-workpieces 500 and the connecting seat 700 can be pushed into the loading cavity at one time, avoiding the use of individual loading and eliminating the need for manual operation of the connecting seat 700. This effectively reduces labor intensity and improves assembly efficiency.

[0025] It should be noted that a snap-fit ​​structure is provided between the sub-workpiece 500 and the connecting seat 700. Therefore, even if the clamping mechanism 200 releases the connecting seat 700 after all sub-workpieces 500 have completed their docking with the connecting seat 700, the positional stability of the connecting seat 700 can be ensured. Specifically, the snap-fit ​​structure includes a snap-fit ​​interface 501 formed on the sub-workpiece 500 and a snap-fit ​​protrusion provided on the connecting seat 700.

[0026] In one embodiment of the present invention, the second push port 102 is located on the lower or upper side of the modular fixture 100. That is, the second push port 102 for the connecting seat 700 to enter can be staggered from the first push port 101 for the sub-workpiece 500 to enter, so that the conveying mechanism of the connecting seat 700 and the pushing mechanism 300 of the sub-workpiece 500 can be staggered, avoiding motion interference between different mechanisms and ensuring that each feeding action can be performed smoothly. At the same time, the clamping mechanism 200 is configured to extend into or out of the modular fixture 100 from the second push port 102. That is, the connecting seat 700 entering the modular fixture 100 and the clamping mechanism 200 entering and exiting the modular fixture 100 can share the second push port 102, reducing the impact of opening too many openings on the modular fixture 100 on its structural strength, and also simplifying the overall structural layout and reducing the processing and manufacturing difficulty of the modular fixture 100. Of course, the present invention is not limited to this. The second push port 102 can also be located on the periphery of the module fixture 100, and the clamping mechanism 200 can also be provided with an opening for entering and exiting the module fixture 100.

[0027] See Figures 3 to 7In one embodiment of the present invention, the second push port 102 is located on the lower side of the module fixture 100, and the clamping mechanism 200 includes a clamping drive member 210 and a gripper body 220. The gripper body 220 extends upward from the upper end of the clamping drive member 210. The clamping drive member 210 is used to drive the gripper body 220 to clamp or release the connecting seat 700. The gripper body 220 is used to extend into the module fixture 100 from the second push port 102 when the connecting seat 700 is clamped. This allows the connector 700 to be transferred to the clamping mechanism 200 first. After the clamping jaws 220 of the clamping mechanism 200 clamp the connector 700, the second push port 102 of the module fixture 100 is aligned with the clamping jaws 220 and the module fixture 100 is pushed downwards, so that the clamping jaws 220 enter the module fixture 100 from the second push port 102. Subsequently, each push mechanism 300 pushes the corresponding sub-workpieces 500 into the module fixture 100 from their respective first push ports 101. After all the sub-workpieces 500 have abutted against the connector 700 and completed the docking, the clamping mechanism 200 releases the connector 700. Then, the module fixture 100 can be lifted vertically upwards to complete the separation from the clamping mechanism 200. The entire pre-assembly process is simple and smooth, with a clear operation procedure, which can effectively improve pre-assembly efficiency. Of course, the present invention is not limited to this. The second push port 102 can also be located on the upper side of the module fixture 100. First, the module fixture 100 is placed in the pre-assembly station, and then the connector 700 is aligned with the second push port 102 of the module fixture 100 and pushed downward until the connector 700 enters the module fixture 100. However, in order to enable the clamping mechanism 200 to clamp the connector 700 after it enters the module fixture 100, the clamping mechanism 200 should be set to enter or exit the module fixture 100 from another opening.

[0028] See Figures 5 to 7 In one embodiment of the present invention, the modular pre-assembly device further includes a support assembly 400. The support assembly 400 is disposed on the upper side of the clamping drive member 210 and has an opening 411 for the gripper body 220 to pass through. The support assembly 400 is configured to support the module fixture 100 upwards. Specifically, the upward-facing side of the support assembly 400 is configured as a horizontal plane to horizontally support the module fixture 100 upwards. By adding the support assembly 400, it can be ensured that the module fixture 100 is stably placed on the upper side of the clamping drive member 210. Furthermore, the opening size of the opening 411 allows the gripper body 220 to clamp or release the connecting seat 700 within it.

[0029] In one embodiment of the present invention, the support assembly 400 includes a support plate 410 and a support frame 420. The support plate 410 is configured to support the upward module fixture 100 and has an opening 411. The support frame 420 includes a lower support and an upper support rod 421 arranged sequentially from bottom to top. The lower support is erected on the outside of the clamping drive member 210 and is configured as the upward support plate 410 on the upper side of the clamping drive member 210. The upper support rod 421 is connected to the lower support and extends upward from the opening 411. The upper end of the upper support rod 421 is configured as a support connecting seat 700. That is, while the module fixture 100 is stably placed on the support plate 410, the upper support rod 421 can provide auxiliary support for the connecting seat 700 in advance, and cooperate with the gripper body 220 to complete the clamping and positioning, further improving the positional accuracy of the connecting seat 700 during pre-assembly and avoiding the connecting seat 700 from tilting or shaking during pre-assembly. Specifically, the support frame 420 can be disposed on the same horizontal plane as the clamping drive member 210. Of course, the present invention is not limited to this. The support assembly 400 may only have a support plate 410, which can be directly disposed on the upper end of the clamping drive member 210. In addition, the support plate 410 and the support frame 420 can be configured as an integrated connection structure or as separate structures.

[0030] In one embodiment of the present invention, the lower support frame includes radial support rods 422 and axial support rods 423. The number of radial support rods 422 and axial support rods 423 is at least two. The at least two radial support rods 422 extend from the same center point in different radial directions and are positioned above the clamping drive member 210, serving as an upward support plate 410. The upper ends of the at least two axial support rods 423 are respectively connected to the ends of the at least two radial support rods 422 away from the center point. The at least two axial support rods 423 are arranged sequentially at intervals around the periphery of the clamping drive member 210. The upper support rod 421 is located at the center point. That is, the axial support rods 423 of the lower support frame can support the radial support rods 422 on the outer periphery of the clamping drive member 210, so that the radial support rods 422 are located above the clamping drive member 210 and form a plane supporting the support plate 410.

[0031] Preferably, the number of radial struts 422 and axial struts 423 is three. The three radial struts 422 extend from the same center point in different radial directions and are evenly spaced. The three axial struts 423 are connected to the three radial struts 422 in a one-to-one correspondence.

[0032] Please see again Figures 5 to 7In one embodiment of the present invention, the number of gripper bodies 220 is at least two, and the at least two gripper bodies 220 are arranged alternately along the circumference of the clamping drive member 210. Each gripper body 220 can move radially under the drive of the clamping drive member 210, thereby clamping or releasing the connecting seat 700 from different directions, jointly ensuring the positional stability of the connecting seat 700 during the pre-assembly process. Further, when the number of sub-workpieces 500 is set to three, and three partitions are arranged alternately on the circumference of the connecting seat 700, so that any two adjacent sub-workpieces 500 can be separated by the corresponding partitions, the number of gripper bodies 220 can be set to three, and the three gripper bodies 220 are respectively arranged one-to-one with the three partitions. When the number of radial support rods 422 and axial support rods 423 is set to three, the three gripper bodies 220 and the three axial support rods 423 are arranged alternately. Furthermore, the clamping drive member 210 includes, but is not limited to, a gripper cylinder.

[0033] In one embodiment of the present invention, the clamping mechanism 200 further includes a fixing base plate 230, which is used to provide a mounting base for the lower end of the clamping drive member 210, thereby facilitating the fixed installation of the clamping mechanism 200. Furthermore, the fixing base plate 230 can also be used to support the axial strut 423.

[0034] like Figure 2As shown, in one embodiment of the present invention, the modular fixture 100 is square in shape and includes a top plate 110, a bottom plate 120, a first side plate 130, a second side plate 140, a first vertical beam 150, and a second vertical beam 160. The top plate 110 and the bottom plate 120 are arranged vertically and alternately. The first side plate 130 and the second side plate 140 are respectively disposed on the first and second sides of the modular fixture 100, which are spaced apart from each other, and are both connected to the top plate 110 and the bottom plate 120. The first vertical beam 150 is located on the first side and the second side of the modular fixture 100. The top plate 110 and the bottom plate 120 are connected at the corners of the three sides. The first vertical beam 150 is spaced apart from the first side plate 130 to form a first push opening 101 on the first side. The second vertical beam 160 is connected to the top plate 110 and the bottom plate 120 at the corners of the second and third sides of the module fixture 100. The second vertical beam 160 is spaced apart from the second side plate 140 to form a first push opening 101 on the second side. The module fixture 100 is open on the third and fourth sides. The first push-out ports 101 on the first and second sides allow two sub-workpieces 500 located on the same ring to be pushed into the modular fixture 100. The modular fixture 100 has open sides on the third and fourth sides. This allows the open side on the fourth side to also serve as a first push-out port 101, allowing a sub-workpiece 500 located on another ring to be pushed into the modular fixture 100. Furthermore, when all sub-workpieces 500 and connecting seats 700 need to be pushed from the modular fixture 100 into the loading cavity of the mother workpiece at once, the open sides on the third and fourth sides can form a pushing channel, facilitating the direct insertion of the corresponding pushing device to complete the pushing action. Simultaneously, the square frame structure is easier to manufacture, has lower processing costs, and its structural strength meets the requirements for pre-assembly and pushing.

[0035] In one embodiment of the present invention, a limiting plate 121 is provided on the base plate 120. The limiting plate 121 is disposed near the third side, and each side of the limiting plate 121 facing the first side and the second side is provided as a limiting contour edge 1211, which is used to fit against the periphery of the sub-workpiece 500. By adding the limiting plate 121 to the base plate 120, the two sub-workpieces 500 pushed into the module fixture 100 from the first side and the second side can be separated and limited, further ensuring the docking accuracy between the sub-workpiece 500 and the connecting seat 700 and improving the accuracy of the pre-installation position. Furthermore, if the sub-workpiece 500 is cylindrical, the limiting contour edge 1211 of the limiting plate 121 can be arc-shaped. It should be noted that the number of sub-workpieces 500 can be set to three. The sub-workpieces 500 pushed in from the first and second sides are located on the outer ring in the filling cavity, while the sub-workpieces 500 pushed in from the fourth side are located on the inner ring in the filling cavity. The two limiting contour edges 1211 on the limiting plate 121 are set at intervals.

[0036] See Figure 1 and Figure 8 In one embodiment of the present invention, the pushing mechanism 300 includes a mounting base 310, a pushing drive 320, and a pushing head 330. The mounting base 310 is fixedly disposed, and the pushing drive 320 is disposed on the mounting base 310 and drivenly connected to the pushing head 330. The pushing drive 320 is used to drive the pushing head 330 to push the sub-workpiece 500 in the carrying fixture 600 into the module fixture 100. Specifically, the pushing drive 320 is configured for automatic control so that all pushing mechanisms 300 can simultaneously push each sub-workpiece 500 into the module fixture 100, thereby improving the overall pre-assembly efficiency. More specifically, the number of pushing mechanisms 300 can be set to three. The three pushing mechanisms 300 are respectively set to correspond one-to-one with the first side, the second side and the fourth side of the module fixture 100. Each pushing mechanism 300 and the clamping mechanism 200 have a loading station. The loading station can be used to place the carrying fixture 600 with the sub-workpiece 500. In addition, the pushing drive 320 can be a cylinder or an electric push rod, which has stable output power and can accurately control the pushing stroke to adapt to the pushing needs of sub-workpieces 500 of different sizes and ensure that the pushing position accuracy meets the assembly requirements.

[0037] In one embodiment of the present invention, a pushing contour surface is formed on the pushing head 330 to conform to the periphery of the sub-workpiece 500. By adding the pushing contour surface, the contact area between the pushing head 330 and the sub-workpiece 500 can be increased, so that the pushing force is applied to the sub-workpiece 500 more evenly, avoiding the sub-workpiece 500 from deflecting during the pushing process, further ensuring the positional accuracy of the sub-workpiece 500 after it is pushed into place, and improving the pre-assembly quality.
