[0034] There are many types of existing wiper structures, such as Figure 1 The wiper head 1 of a windshield wiper shown in FIG. The wiper head 1 has multiple through-holes for assembling various components, including a bushing 2 and a rivet 3. Currently, in the production process of such wipers, the bushing 2, rivet 3, and other components are assembled manually, which is time-consuming, labor-intensive, and inefficient.

[0035] The present invention proposes an automobile wiper rod head assembly device, referring to Figure 1 The automobile wiper head assembly equipment includes a handling robot 10 and a conveying device 100, a loading platform 200, a sleeve assembly device 300, a sleeve punching and riveting device 400, a rivet assembly device 500, and a rivet riveting device 600 arranged in sequence;

[0036] The conveying device 100 is used to convey unassembled wiper rod heads. A loading robot 20 is provided on one side of the conveying device 100. The loading robot 20 is used to transfer the wiper rod heads conveyed by the conveying device 100 to the loading platform 200. The transporting robot 10 is used to transport the wiper rod heads between the loading platform 200, the sleeve assembly device 300, the sleeve punching and riveting device 400, the rivet assembly device 500 and the rivet riveting device 600.

[0037] The automobile wiper rod head assembly equipment proposed in this embodiment is used to assemble automobile wiper rod heads to assemble parts on the automobile wiper rod heads, wherein, with reference to Figure 1 The wiper head has through holes for mounting components, including bushings and rivets. Specifically, the automobile wiper head assembly equipment primarily comprises a handling robot 10, a conveying device 100, a loading platform 200, a bushing assembly device 300, a bushing punching and riveting device 400, a rivet assembly device 500, a rivet screwing device 600, and a loading robot 20. Each of the aforementioned devices and robots may be installed on the same machine base or on different machine bases, and their layout may be linear, including but not limited to this, depending on actual conditions.

[0038] The working principle of the automobile wiper rod head assembly equipment is: the conveying device 100 conveys the unassembled wiper rod head, and then the loading robot 20 transfers the wiper rod head conveyed by the conveying device 100 to the loading platform 200, and then the handling robot 10 transports the wiper rod head between the loading platform 200, the sleeve assembly device 300, the sleeve punching and riveting device 400, the rivet assembly device 500 and the rivet riveting device 600, among which the sleeve assembly device 300, the sleeve punching and riveting device 400, the rivet assembly device 500 and the rivet riveting device 600 perform sleeve assembly, sleeve riveting, rivet assembly and rivet riveting and other process operations on the wiper rod head in sequence.

[0039] The conveying device 100 is used to transport unassembled wiper rod tips. The conveying device 100 can be a conveyor belt, with the end of the conveyor belt docked with the loading platform 200. The loading platform 200 is equipped with a positioning fixture to temporarily place the wiper rod tips until they are transported by the handling robot 10. The wiper rod tips conveyed by the conveying device 100 are transferred one by one to the loading platform 200 via the loading robot 20. The loading robot 20 can adopt a variety of structural forms, and the loading method can be suction-type, clamping-type, etc., depending on actual circumstances and is not limited to this.

[0040] The sleeve assembly device 300 is used to automatically assemble the sleeve on the wiper rod head; the sleeve riveting device 400 is used to perform riveting operations on the sleeve on the wiper rod head to rivet the sleeve to the wiper rod head; the rivet assembly device 500 is used to automatically assemble rivets on the wiper rod head; the rivet riveting device 600 is used to perform riveting operations on the rivets on the wiper rod head to rivet the rivets to the wiper rod head. Among them, the structural structure of each device can be designed according to actual conditions and will not be described in detail here; some specific implementation structural schemes of each device will be described in detail in subsequent embodiments. In addition, a blanking mechanism can also be set at the subsequent workstation of the rivet riveting device 600, and the structural form of the blanking mechanism can adopt various forms, such as Figure 1 The tilted material discharge chute shown can be connected to a material frame or a conveyor belt; the wiper rod head is transported to the material discharge chute by a transport robot 10 to discharge the assembled wiper rod head.

[0041] The transport robot 10 is used to transport wiper rod heads between the loading platform 200 and various devices. Specifically, after a wiper rod head completes a corresponding process at one device, it is transported to the next device for the next process via the transport robot 10. The transport robot 10 can be one or multiple, depending on the specific situation. When there is only one transport robot 10, the robot 10's actuator end is equipped with multiple gripping units, allowing the multiple gripping units to simultaneously grasp the wiper rod heads at the loading platform 200 and various devices. After moving, the multiple gripping units then simultaneously place the multiple wiper rod heads, effectively moving the wiper rod heads back one station. When there are multiple transport robots 10, one transport robot 10 can be positioned between two adjacent devices, allowing the multiple transport robots 10 to coordinate and simultaneously grasp and place the wiper rod heads at the loading platform 200 and various devices. The transport robot 10 can adopt a variety of structural forms, and the handling method can be suction-type, clamping-type, or other methods, depending on the specific situation and is not limited to this.

[0042] That is, the automobile wiper rod head assembly equipment replaces manual labor to realize the automatic assembly of the automobile wiper rod head, which saves time and labor and has high assembly efficiency.

[0043] In a preferred embodiment, referring to Figure 3 and Figure 4 The sleeve assembly device 300 includes a first positioning fixture 310, a feeding mechanism 320 and a pushing mechanism 330. The first positioning fixture 310 places the wiper rod head, the feeding mechanism 320 conveys parts, and the pushing mechanism 330 is located on one side of the first positioning fixture 310. The discharge end of the feeding mechanism 320 is located between the first positioning fixture 310 and the pushing mechanism 330. The pushing mechanism 330 includes a pin 331 and a first driving component 332. The first driving component 332 drives the pin 331 to move, so that the pin 331 contacts the parts transmitted from the discharge end of the feeding mechanism 320, and pushes the parts to move and be inserted into the through hole of the wiper rod head on the first positioning fixture 310.

[0044] In this embodiment, the first positioning jig 310 is used to place the wiper rod head, that is, to place the wiper rod head carried by the handling robot 10 from the loading platform 200. The structural structure of the first positioning jig 310 is set according to the shape of the wiper rod head and is not limited to this. When the wiper rod head is placed on the first positioning jig 310, the first positioning jig 310 holds the wiper rod head, thereby achieving the positioning of the wiper rod head during the assembly of parts. The function of the feeding mechanism 320 is to provide parts (i.e., bushings) and load the parts. The feeding mechanism 320 can adopt various structural forms. For example, the feeding mechanism 320 adopts a vibration disk 321 and a linear feeder 322. One end of the linear feeder 322 is connected to the outlet of the vibration disk 321, and the other end is the discharge end of the feeding mechanism 320. This can realize the automatic sorting and one-by-one delivery of parts, and the feeding is stable and not prone to errors. In addition, other forms can also be used. The pusher mechanism 330 pushes components from the feeder mechanism 320 into the through-holes of the wiper head for insertion, thereby assembling the components onto the wiper head. The pusher mechanism 330 primarily drives the ejector pin 331 through its first drive assembly 332, which in turn pushes the components. The first drive assembly 332 can be a linear cylinder, including but not limited to a linear cylinder.

[0045] Among them, the principle of sleeve assembly is: the wiper rod head to be assembled is placed on the first positioning fixture 310, and the parts are conveyed to its discharge end through the feeding mechanism 320. The ejector pin 331 of the pushing mechanism 330 moves under the drive of the first driving component 332, so that the ejector pin 331 contacts the parts and pushes the parts to move and be inserted into the through hole of the wiper rod head on the first positioning fixture 310, thereby assembling the parts to the wiper rod head.

[0046] Further, refer to Figures 3 to 5The discharge end of the feeding mechanism 320 is provided with a receiving seat 340. The receiving seat 340 is provided with a pushing channel 341 and an inlet 342 connected to the pushing channel 341. The inlet 342 is connected to the discharge end of the feeding mechanism 320. A ejector pin 331 extends from one end opening of the pushing channel 341. The other end opening of the pushing channel 341 is opposite to the through hole of the wiper rod head on the first positioning fixture 310. Parts discharged from the discharge end of the feeding mechanism 320 automatically enter the pushing channel 341 through the inlet 342 of the receiving seat 340. In this way, the ejector pin 331 moves in the pushing channel 341, pushing the parts in the pushing channel 341 into the through hole of the wiper rod head, thereby inserting the parts into the wiper rod head. The receiving seat 340 receives the parts transmitted by the feeding mechanism 320, and a pushing channel 341 is correspondingly provided on the receiving seat 340, so that the parts can be accurately positioned before assembly, thereby improving the assembly accuracy.

[0047] In a preferred embodiment, referring to Figure 3 and Figure 4 The sleeve assembly device 300 further includes a guide mechanism 350 , and the guide mechanism 350 and the pushing mechanism 330 are located on opposite sides of the first positioning fixture 310 ;

[0048] The guiding mechanism 350 includes a guiding needle 351 and a second driving assembly 352. The second driving assembly 352 drives the guiding needle 351 to move. The guiding needle 351 passes through the through hole of the wiper rod head on the first positioning fixture 310, so as to abut against the opposite ends of the components transmitted from the discharge end of the feeding mechanism 320 with the ejector pin 331, and can jointly drive the components to move and be inserted into the through hole of the wiper rod head on the first positioning fixture 310.

[0049] In this embodiment, after the component is delivered from the discharge end of the feeding mechanism 320, the guide pin 351, driven by the second drive assembly 352, moves through the through-hole of the wiper rod head on the first positioning fixture 310 and reaches the other side of the first positioning fixture 310, where it abuts against the opposite ends of the component with the ejector pin 331. That is, the ejector pin 331 and the guide pin 351 jointly clamp the component. Then, the ejector pin 331, driven by the first drive assembly 332, moves to jointly drive the component to be inserted into the through-hole of the wiper rod head on the first positioning fixture 310 with the guide pin 351. It can be seen that the function of the guide mechanism 350 is to cooperate with the pusher mechanism 330 to guide the insertion of the component into the through-hole of the wiper rod head, prevent the pusher mechanism 330 from pushing the component too far into the wiper rod head, ensure the accuracy of the component insertion position, and improve assembly accuracy. Among them, the second drive assembly 352 can adopt a linear cylinder, including but not limited to this. It should be noted that the guide needle 351 and the aforementioned ejector pin 331 may also be referred to by other terms, such as guide rod and ejector rod, guide head and push head, etc., including but not limited to these.

[0050] In a preferred embodiment, referring to Figure 3 The sleeve assembly device 300 further includes a pressing mechanism 360, which is located on one side of the first positioning fixture 310 and is used to press the wiper rod head on the first positioning fixture 310. In this embodiment, the pressing mechanism 360 presses the wiper rod head on the first positioning fixture 310 to cooperate with the first positioning fixture 310 to fix the wiper rod head, preventing the wiper rod head from loosening and affecting the alignment of its through hole with the component. The structural form of the pressing mechanism 360 can be various, for example, referring to Figure 6 The holding mechanism 360 includes a holding member 361, a rotating pressure rod 362, and a driving member 363. The holding member 361 is mounted on the rotating pressure rod 362. The driving member 363 drives the rotating pressure rod 362 to rotate, thereby moving the holding member 361 to the wiper rod head and pressing the wiper rod head. Preferably, the holding member 361 can be a rubber-coated screw, providing a flexible pressure on the wiper rod head. The driving member 363 can be a rotary cylinder, including but not limited to such a rotary cylinder.

[0051] In a preferred embodiment, the structure of the rivet assembly device 500 is the same as that of the sleeve assembly device 300. The specific structure of the rivet assembly device 500 in this embodiment can refer to the sleeve assembly device 300 in the aforementioned embodiment, including the first positioning fixture 310, the feeding mechanism 320, and the pushing mechanism 330, and will not be further described here.

[0052] In a preferred embodiment, referring to Figure 7The sleeve riveting device 400 includes a second positioning fixture 410 and a riveting mechanism 420. The second positioning fixture 410 is used to place the wiper rod head. The riveting mechanism 420 includes two punches 421, a first transmission assembly 422, and a third drive assembly 423. The two punches 421 are arranged on opposite sides of the second positioning fixture 410. The input end of the first transmission assembly 422 is connected to the output shaft of the third drive assembly 423. The output end of the first transmission assembly 422 is connected to the two punches 421. The third drive assembly 423 drives the first transmission assembly 422 to drive the two punches 421 to move toward each other so as to respectively abut the two ends of the sleeve on the wiper rod head and rivet the sleeve to the wiper rod head. In this embodiment, the function of the second positioning fixture 410 is to place the wiper rod head, that is, to place the wiper rod head carried by the handling robot 10 from the sleeve assembly device 300. The structural structure of the second positioning fixture 410 is set according to the shape of the wiper rod head and is not limited to this. The punches 421 of the riveting mechanism 420 are cylindrical, with the axes of the two punches 421 collinear with the axis of the sleeve to ensure machining accuracy. A first transmission assembly 422 is used to transmit power to the two punches 421. The first transmission assembly 422 is located below the two punches 421. The input end of the first transmission assembly 422 is connected to the output shaft of the third drive assembly 423, and its output end is connected to the two punches 421. The third drive assembly 423 drives the first transmission assembly 422, thereby moving the two punches 421 toward or away from each other. The third drive assembly 423 can be an electric cylinder, including but not limited to an electric cylinder.

[0053] The sleeve riveting principle is as follows: the wiper rod head is placed on the second positioning fixture 410, with the ends of the sleeve on the wiper rod head aligned with the two punches 421. The third drive assembly 423 drives the first transmission assembly 422, driving the two punches 421 simultaneously toward the wiper rod head, punching and riveting the sleeve on the wiper rod head to achieve riveting.

[0054] Among them, reference Figure 7 and Figure 8 A base 424 may be provided, with the second positioning fixture 410 mounted on the base 424. The first transmission assembly 422 includes a connecting plate 4221, one end of which is connected to the third driving assembly 423, and the other end of which is connected to two movable plates 4222, each of which is slidably connected to the base 424. One end of the punch 421 is slidably connected to the base 424, and the other end is movably connected to the movable plate 4222.

[0055] The connecting plate 4221 has three connecting ends, one of which is connected to the output execution end of the third drive assembly 423, and the other two connecting ends are respectively connected to two movable plates 4222. The movable plates 4222 are slidably connected to the base 424 and can move in the vertical direction. A shaft sleeve is provided at one end of the punch 421, and a shaft sleeve seat is installed on the base 424. The shaft sleeve is installed on the shaft sleeve seat, and the punch 421 can slide in the horizontal direction. The movable plate 4222 is provided with an arc-shaped guide groove 4222a. The punch 421 is movably connected to the arc-shaped guide groove 4222a. When the movable plate 4222 moves upward, the punch 421 moves along the arc-shaped guide groove 4222a toward the other punch 421. The arc-shaped guide groove 4222a is mainly used to control the direction and stroke of the punch 421.

[0056] During operation, the third driving assembly 423 drives the connecting plate 4221 to move upward, and the connecting plate 4221 drives the two movable plates 4222 to move upward at the same time. The two movable plates 4222 drive the two punches 421 to move toward each other, and at the same time, the wiper rod head is punched and riveted to achieve riveting.

[0057] In a preferred embodiment, referring to Figure 7 and Figure 9 The sleeve riveting device 400 also includes a cutting mechanism 430, which is connected to the first transmission assembly 422 and is used to remove the scrap of the wiper rod head from the second positioning fixture 410. After injection molding, the wiper rod head typically has residual scrap at the end, which needs to be removed during production. In this embodiment, while the first transmission assembly 422 drives the two punches 421 for riveting, the cutting mechanism 430 simultaneously removes the scrap at the end of the wiper rod head, eliminating the need for riveting and then cutting, thereby improving production efficiency.

[0058] Furthermore, the cutting mechanism 430 includes a cutter assembly 431 and a second transmission assembly 432. One end of the second transmission assembly 432 is connected to the cutter assembly 431, and the other end of the second transmission assembly 432 is connected to the first transmission assembly 422. In this embodiment, the first transmission assembly 422 drives the second transmission assembly 432 to move, and the second transmission assembly 432 drives the cutter assembly 431 to cut the edge material of the wiper rod head. Specifically, the cutter assembly 431 includes a fixed seat 4311, a movable seat 4312, and a cutter 4313. The fixed seat 4311 is mounted on the base 424, the movable seat 4312 is slidably connected to the fixed seat 4311, and the cutter 4313 is mounted on the movable seat 4312. A slide groove is formed on the fixed seat 4311, and the movable seat 4312 is accommodated in the slide groove and can slide within the slide groove. The cutter 4313 is mounted on the side of the movable seat 4312 facing the wiper head. A return spring is located within the chute, with one end of the return spring abutting against the fixed seat 4311 and the other end against the movable seat 4312. During operation, the movable seat 4312, driven by the second transmission assembly 432, moves toward the wiper head, and the cutter 4313 on the movable seat 4312 removes the scrap material from the wiper head. At this point, the return spring is compressed by the pressure of the movable seat 4312. When the second transmission assembly 432 is activated again, the spring's return force causes the movable seat 4312 to move away from the wiper head, automatically retracting the cutter.

[0059] Furthermore, the second transmission assembly 432 includes a rotating rod 4321 and a guide plate 4322. The guide plate 4322 is connected to the first transmission assembly 422. The rotating rod 4321 is rotatably connected to the fixed base 4311. One end of the rotating rod 4321 abuts the movable base 4312, and the other end abuts the guide plate 4322. Specifically, the guide plate 4322 is mounted on the first transmission assembly 422. The outer side of the guide plate 4322 is arc-shaped, and the lower end protrudes outward. The rotating rod 4321 is rotatably connected to the fixed base 4311. Guide wheels are provided at both ends of the rotating rod 4321, one end of which abuts the guide plate 4322 and the other end abuts the movable base 4312. During operation, the guide plate 4322 moves upward, driving the rotating rod 4321 to rotate. The upper end of the rotating rod 4321 rotates toward the wiper rod head, driving the movable base 4312 to move.

[0060] In a preferred embodiment, referring to Figure 10The rivet riveting device 600 includes a third positioning jig 610 and two riveting mechanisms 620. The third positioning jig 610 is used to position the wiper rod head. The two riveting mechanisms 620 are located on opposite sides of the third positioning jig 610. The riveting mechanisms 620 include a rivet head 621 and a fourth drive assembly 622. Driven by the two fourth drive assemblies 622, the two rivet heads 621 rotate and move toward each other to respectively abut the ends of the rivet on the wiper rod head and rivet the rivet to the wiper rod head. In this embodiment, the function of the third positioning jig 610 is to position the wiper rod head, that is, to position the wiper rod head transferred from the rivet assembly device 500 by the handling robot 10. The structural configuration of the third positioning jig 610 is configured based on the external shape of the wiper rod head and is not limited thereto. The riveting mechanisms 620 are primarily used to rivet the rivet on the wiper rod head, thereby riveting the rivet to the wiper rod head. There are two rotary riveting mechanisms 620, which are arranged on opposite sides of the third positioning fixture 610. Each rotary riveting mechanism 620 includes a rivet head 621 and a fourth drive assembly 622. The output actuator end of the fourth drive assembly 622 is connected to the rivet head 621, and the rivet head 621 can move and rotate under the drive of the fourth drive assembly 622. The rotary riveting mechanism 620 adopts the structural arrangement of the rivet head 621 and the fourth drive assembly 622, which can refer to the existing rotary riveting machine, and its specific structure is not described in detail here.

[0061] The rivet-jointing principle is as follows: a wiper rod is placed on the third positioning jig 610, with the ends of the wiper rod sleeve aligned with the two rivet heads 621. The fourth drive assembly 622 rotates the rivet heads 621 and moves them toward the sleeve on the wiper rod. The two rivet heads 621 abut the ends of the rivet on the wiper rod, engaging the rivet.

[0062] It should be noted that a corresponding holding mechanism 360 such as that in the sleeve assembly device 300 may also be provided in the sleeve punching and riveting device 400 and the rivet riveting device 600 to hold the wiper rod head on the corresponding positioning fixture when executing the corresponding processing steps.

[0063] In a preferred embodiment, referring to Figure 1 and Figure 11 The automobile wiper rod head assembly equipment further includes a shaping device 700, which is arranged on one side of the rivet riveting device 600. The shaping device 700 includes a turntable 710, a plurality of fourth positioning fixtures 720, a shaping press head 730 and a fifth driving assembly 740.

[0064] The fourth positioning jig 720 is used to place the wiper rod head. Several fourth positioning jigs 720 are circumferentially arranged on the turntable 710. The turntable 710 is used to rotate to drive the several fourth positioning jigs 720 to reach the bottom of the shaping head 730 one by one. The fifth driving assembly 740 is used to drive the shaping head 730 to contact or leave the wiper rod head on the fourth positioning jig 720. The shaping head 730 is used to perform shaping processing on the wiper rod head.

[0065] In this embodiment, after the rivet riveting process is completed, the wiper rod head is shaped by the shaping device 700 to ensure that its appearance meets the requirements for use before being cut. Specifically, the fourth positioning fixture 720 on the turntable 710 receives the wiper rod head transferred from the rivet riveting device 600, and the wiper rod head can be transported by the handling robot 10. The turntable 710 then rotates to drive the fourth positioning fixture 720 to the bottom of the shaping head 730. The fifth drive assembly 740 drives the shaping head 730 downward to contact the wiper rod head on the fourth positioning fixture 720 and apply pressure to it, thereby shaping the wiper rod head. After a certain shaping period, the fifth drive assembly 740 drives the shaping head 730 upward to remove the wiper rod head from the fourth positioning fixture 720. After the wiper rod head is shaped, the turntable 710 continues to rotate to drive the fourth positioning fixture 720 to leave from under the shaping head 730, and drives another fourth positioning fixture 720 to reach under the shaping head 730 to continue the shaping operation of the next wiper rod head. As a preferred design, the fifth drive assembly 740 can be a cylinder, including but not limited to this. Figure 11 As shown, two fourth positioning fixtures 720 can be used. The rotation drive of the turntable 710 can be a combination of a motor and multiple transmission components such as a transmission belt, and those skilled in the art can design it according to actual conditions.
