[0073] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0074] like Figures 1 to 11As shown, the present invention is an integrated assembly device for an automobile headrest frame 1, which is used to assemble a headrest support rod 10, an unlocking rod 11, a steel wire 12 and an outer guide sleeve 13 to the headrest frame 1 in sequence, wherein the assembly device includes: a frame 2, on which a first assembly area 20, a second assembly area 21 and a third assembly area 22 are arranged at intervals; a positioning mechanism 3 and a support rod assembly mechanism 4, which are arranged in the first assembly area 20, the positioning mechanism 3 is used to store and lock the headrest frame 1 to be assembled, so that the support rod assembly mechanism 4 can push the headrest support rod 10 to be inserted into the headrest frame 1; an unlocking rod assembly mechanism 5, which is arranged in the first assembly area 20, the unlocking rod assembly mechanism 5 is used to push the unlocking rod 11 to be inserted into the headrest frame 1 and press against the headrest support rod 10, and transfer the formed semi-finished product to the second assembly area 21; a receiving mechanism 6 and a feeding mechanism 7, which are arranged in the second assembly area 21, the receiving mechanism 6 is used to place and fix the semi-finished product and the outer guide sleeve 13 at intervals; the feeding mechanism 7 is used to transfer the semi-finished product and the outer guide sleeve 13 to the second assembly area 21. The guide sleeve 13 is transferred to the third assembly area 22. The feeding mechanism 7 includes a clamping member 70 and an adjusting component 71. The clamping member 70 is used to clamp the semi-finished product. The movable end of the adjusting component 71 is connected to a picking cylinder 710 for grabbing the outer guide sleeve 13. The adjusting component 71 is movably inserted in the clamping member 70 and can be moved closer to or farther from the clamping member 70 to adjust the relative position and distance between the outer guide sleeve 13 and the semi-finished product. The outer guide sleeve assembly mechanism 8 and the unloading mechanism 9 are arranged in the third assembly area 22. The unloading mechanism 9 is provided with an auxiliary block 90, and the outer guide sleeve assembly mechanism 8 is provided with a material moving module 80 and a retractable pre-pressing block 810; the pre-pressing block 810 can be movably pressed against the headrest support rod 10 when the semi-finished product is placed in the outer guide sleeve assembly mechanism 8, so that the unloading mechanism 9 drives the auxiliary block 90 to press the headrest frame 1, so that when the material moving module 80 drives the outer guide sleeve 13 to be movably sleeved on the headrest support rod 10, the front end of the outer guide sleeve 13 can cross the auxiliary block 90 and movably buckle the headrest frame 1 and press against the steel wire 12.
[0075] This solution is mainly to realize the integrated assembly of the automobile headrest frame 1 parts, specifically, Figures 1 to 11As shown, in this embodiment, three assembly areas with different assembly steps are divided on the frame 2, wherein, before the assembly operation starts, the worker or the manipulator can place the oiled headrest support rod 10 and the headrest frame 1 to be assembled into the positioning mechanism 3 to ensure that they will not be displaced during the assembly process, thereby providing a guarantee for the accuracy of the assembly; then, the support rod assembly mechanism 4 can push the headrest support rod 10 into the headrest frame 1, and then, the unlocking rod assembly mechanism 5 pushes the unlocking rod 11 inside it into the headrest frame 1, and makes it press against the headrest support rod 10 to form the desired semi-finished product. After completing these steps, the semi-finished product will be transferred to the second assembly area 21; and in the second assembly area 21 .... In the distribution area 21, the receiving mechanism 6 can fix the semi-finished product transferred from the first assembly area 20. When the manipulator or the worker synchronously fixes the outer guide sleeve 13 to be assembled in the receiving mechanism 6, the stability of the semi-finished product and the outer guide sleeve 13 in subsequent operations is ensured. When the receiving mechanism 6 moves to the bottom of the feeding mechanism 7, the clamping member 70 on the feeding mechanism 7 is used to clamp the semi-finished product, and the adjusting component 71 adjusts the position of the picking cylinder 710 through the movable end to ensure that the picking cylinder 710 completes the stable grasping of the outer guide sleeve 13. It should be noted that the adjusting component 71 can drive the picking cylinder 710 to be close to the clamping member 70. The outer guide sleeve 13 and the semi-finished product can be moved closer or farther away, thereby accurately adjusting the relative position and distance between the outer guide sleeve 13 and the semi-finished product, which not only ensures the smoothness and accuracy of the subsequent assembly between the two, but also enables the structure to be flexibly adjusted according to the headrest frame 1 and the outer guide sleeve 13 of different sizes, ensuring the versatility and adaptability of the equipment; and when the semi-finished product is placed in the outer guide sleeve assembly mechanism 8, the pre-pressing block 810 at the bottom of the frame 2 can pre-press the headrest support rod 10 to ensure that the unloading mechanism 9 drives the auxiliary block 90 to press stably on the headrest frame 1. It is worth noting that the unloading mechanism 9 has completed the grabbing of the semi-finished product at this time, so in the subsequent outer guide sleeve After 13 is assembled with the semi-finished product into the required finished product, the unloading operation can be completed quickly, which reduces unnecessary waiting time and material transfer time, makes each assembly process closely connected, and thus improves the overall assembly efficiency; when the above-mentioned picking cylinder 710 places the outer guide sleeve 13 to be assembled into the material transfer module 80, the pre-pressing block 810 shrinks to the bottom of the frame 2, and in the process of the outer guide sleeve assembly mechanism 8 driving the material transfer module 80 to move, the outer guide sleeve 13 can cross the auxiliary block 90, and then flexibly snap onto the headrest frame 1 and press against the steel wire 12 (at this time, it is the finished product to be assembled in this embodiment), effectively ensuring the flexibility of assembly and the uniformity of assembly quality. It can be seen that this solution realizes the efficient operation of the assembly line by dividing the assembly process into three independent areas, each area focusing on a specific assembly task, and greatly shortens the assembly time of a single product.
[0076] The receiving mechanism 6 includes: a moving seat 60 and a rotating motor 61, a slider 600 is arranged at the bottom of the moving seat 60, a rolling member 610 is connected to the output end of the rotating motor 61, a slide rail 23 and a rack 24 are arranged on the frame 2, and the rolling member 610 is movably engaged with the rack 24, so that the slider 600 can drive the moving seat 60 to reciprocate along the length direction of the slide rail 23; a rotating shaft 62 and a linear cylinder 63, the rotating shaft 62 is movably connected to the moving seat 60, and a rotating disk 620 is connected to the top of the rotating shaft 62, and the linear cylinder 63 is arranged on the moving seat 60. The output end of the linear cylinder 63 is hinged with a fixed shaft 630, and the rotation center of the fixed shaft 630 is arranged parallel to the rotation axis of the rotating shaft 62; the storage table 64 can be switched between the initial position and the assembly position of the rotating disk 620, and the rotating disk 620 is also provided with an outer guide sleeve mold 621 installed at a distance from the storage table 64. The storage table 64 in the initial position is used to receive the semi-finished product, and the storage table 64 in the assembly position can be used for the steel wire 12 to be assembled into the headrest frame 1, and the outer guide sleeve 13 to be assembled is fixed on the outer guide sleeve mold 621.
[0077] like Figures 1 to 4 As shown, when the assembled semi-finished product is transferred to the receiving mechanism 6 through the unlocking rod assembly mechanism 5, the storage table 64 in the initial position can limit and fix the semi-finished product. It should be noted that the initial position refers to the posture maintained by the headrest support rod 10 after the headrest frame 1 is inserted. During the process of transferring the semi-finished product by the unlocking rod assembly mechanism 5, the overall position of the semi-finished product does not change. Only when the linear cylinder 63 pulls the fixed shaft 630 to move, because the axis line of the fixed shaft 630 is eccentrically set relative to the axis line of the rotating shaft 62 on the rotating disk 620, the rotating disk 620 is driven to rotate along the axis line of the rotating shaft 62 as the fixed shaft 630 moves. Figure 2 Rotate 90 degrees clockwise (i.e. Figure 2 The storage table 64 shown in the assembly position provides sufficient space and convenience for workers or manipulators to buckle the steel wire 12 into the headrest frame 1 and fix the outer guide sleeve 13 to the outer guide sleeve mold 621. On the other hand, it provides advance auxiliary preparation for subsequent assembly operation steps to ensure the smooth connection of each assembly process.
[0078] It is worth noting that when the storage table 64 is switched to the assembly position and the outer guide sleeve 13 is accurately placed in the outer guide sleeve mold 621, the present embodiment can also be provided with a bearing plate 65 between the movable seat 60 and the rotating plate 620, and the bearing plate 65 is used to install the displacement cylinder 56 and the rotating shaft 62, and a supporting cylinder 66 is connected to the bottom of the bearing plate 65, and the supporting cylinder 66 can be used to drive Figure 3The carrier plate 65 and all the components above it are lifted or lowered relative to the moving seat 60, so that workers or manipulators can place the outer guide sleeve 13, and it is also convenient for the subsequent picking cylinder 710 and the clamping member 70 to clamp the product; after all the assembly preparations are completed, the rotating motor 61 starts to work, and through the engagement of the rolling member 610 with the rack 24, the moving seat 60 is driven to move along the length direction of the slide rail 23 toward the position of the feeding mechanism 7. The equipment can realize automated or even fully automated operations, reducing the opportunity for workers to directly contact heavy machinery, improving safety and overall assembly efficiency. Preferably, for the receiving mechanism 6 used in this embodiment, two groups of the receiving mechanism 6 can be spaced apart in the vertical direction of the frame 2, which is conducive to saving the overall assembly cycle time and further improving the assembly efficiency.
[0079] The clamping member 70 includes: a fixed bracket 700, and a material transfer linear guide 72 is also arranged on the feeding mechanism 7, one end of the fixed bracket 700 is connected to the output end of the material transfer linear guide 72, and the other end is installed with a detection column 701, and the detection column 701 is used to detect the position of the semi-finished product; a first grabbing cylinder 702 and a second grabbing cylinder 703 are arranged on the fixed bracket 700 along the vertical direction, and the first grabbing cylinder 702 is symmetrically provided with a first clamping jaw 702a facing the inside thereof, and the second grabbing cylinder 703 is symmetrically provided with a second clamping jaw 703a facing the outside, the spacing between the first clamping jaws 702a is smaller than the spacing between the second clamping jaws 703a, and the first clamping jaw 702a and the second clamping jaw 703a are respectively used to clamp the inner and outer walls of the headrest support rod 10 to reduce the deformation of the headrest support rod 10.
[0080] like Figures 5 and 6 As shown, the material transfer linear guide rail 72 in this embodiment is formed by connecting a longitudinal drive rail and a horizontal drive rail, wherein the fixed bracket 700 is installed at the output end of the longitudinal drive rail. After the control system receives the signal from the detection column 701 that the semi-finished product and the outer guide sleeve 13 are moved into place, the first grabbing cylinder 702 and the second grabbing cylinder 703 can synchronously complete the grabbing action of the semi-finished product (mainly the entire semi-finished product after grabbing the headrest frame 1). In this process, the first clamping jaw 702a and the second clamping jaw 703a of this embodiment adopt the design of inner and outer clamping jaws, which can evenly distribute the points of force while clamping, effectively avoiding unnecessary deformation of the semi-finished product during the handling process, and ensuring that the appearance and quality of the product are not affected. For this reason, by adjusting the spacing of the first clamping jaw 702a or the second clamping jaw 703a, the clamping member 70 can be suitable for grabbing headrest frames 1 of different sizes, and has strong adaptability and flexibility. In addition, it should be noted that the rolling element 610 in this embodiment can be replaced by a gear 730 or a rotating wheel with a protruding tooth block or other structures.
[0081] The adjustment component 71 also includes: a driving member 73, which is installed on the fixed bracket 700, and the output end of the driving member 73 is connected to the gear 730; a plurality of guide rods 74, and a fixed guide sleeve 700a is connected inside the fixed bracket 700, and each fixed guide sleeve 700a is movably connected to the guide rod 74, and a connecting plate 740 is provided at the end of the guide rod 74, and the picking cylinder 710 is installed on the connecting plate 740; a moving rod 75, which is movably connected to the fixed bracket 700 and is arranged parallel to the guide rod 74, and a plurality of mutually connected convex teeth 750 are arranged in an array on the moving rod 75, and the convex teeth 750 are movably engaged with the gear 730.
[0082] Further, if Figures 5 and 6 As shown, in addition to grabbing the above-mentioned semi-finished product, this embodiment can also pick up the outer guide sleeve 13. Specifically, when the driving member 73 drives the gear 730 to rotate, the gear 730 meshes with the cam on the moving rod 75, so that the rotation of the gear 730 can drive the moving rod 75 to move along its axial direction, thereby realizing the precise positioning of the picking cylinder 710 on the connecting plate 740, ensuring that the picking cylinder 710 can accurately clamp the outer guide sleeve 13 in the outer guide sleeve backing mold 621. It is also because of the forward and reverse rotation of the driving member 73 that the picking cylinder 710 can move in both directions relative to the fixed bracket 700 (i.e., approach or move away), so as to adapt to different work requirements. For example, the position of the picking cylinder 710 can be flexibly adjusted according to the different sizes or position requirements of the headrest support rod 10, and it also brings great convenience to the subsequent assembly operation steps of the outer guide sleeve 13. It should be noted that the driving member 73 in this embodiment can be replaced by other driving devices such as a stepping motor and a servo motor.
[0083] The outer guide sleeve assembly mechanism 8 also includes: a contour seat 82, the bottom of which is connected to a lifting cylinder 820, and the lifting cylinder 820 is used to adjust the height position of the contour seat 82 in the frame 2; a contraction cylinder 83, the output end of the contraction cylinder 83 is connected to a lifting plate 830, both ends of the lifting plate 830 are equipped with a pre-compression cylinder 81, and the pre-compression block 81 is connected to the output end of the pre-compression cylinder 81; a sliding component 84, which is arranged in the frame 2, and a follower rod 840 is movably connected to the sliding component 84, and the follower rod 840 can be synchronously pressed against the side wall of the headrest frame 1 when the sliding component 84 pushes the material moving module 80 to approach the contour seat 82.
[0084] like Figures 7 to 9As shown, when the material transfer linear guide 72 moves the fixed bracket 700 to one side of the contour seat 82, the first clamping jaw 702a and the second clamping jaw 703a can place the clamped semi-finished product in the contour seat 82, thereby realizing the positioning of the semi-finished product before the outer guide sleeve 13 is assembled; it is also because the above-mentioned gear 730 and the rack 24 cooperate to drive the movement of the picking cylinder 710, so that the picking cylinder 710 can accurately place the outer guide sleeve 13 in the material transfer module 80, ensuring the smoothness and accuracy of subsequent assembly; it should be noted that the position where the outer guide sleeve 13 needs to be assembled for different models of headrest skeletons 1 is also different, so before the assembly is started, the lifting cylinder 820 is required to adjust the position of the contour seat 82 to ensure that the outer guide sleeve 13 can be accurately inserted into the headrest skeleton 1 during the movement of the material transfer module 80 pushed by the sliding assembly 84. Moreover, when the semi-finished product is placed in the contour seat 82, the retracting cylinder 83 can drive the lifting plate 830 to lift upward, so that the pre-stressing cylinder 81 can drive the pre-stressing block 810 to be pressed against the headrest support rod 10. This operation process provides a guarantee for the stability of the blanking mechanism 9 when grabbing the headrest frame 1, and also ensures that the auxiliary block 90 can be accurately pressed against the top of the headrest frame 1. As the retracting cylinder 83 drives the pre-stressing block 810 to retract to the bottom of the frame 2 (to avoid position interference with the pre-stressing block 810 during subsequent assembly actions), the sliding assembly 84 can push the material moving module 80 toward the contour seat 82. On the basis of the follower rod 840 pressing against the side wall of the headrest frame 1 to ensure the assembly stability, the outer guide sleeve 13 can cross the auxiliary block 90 and insert the headrest frame 1 and press against the steel wire 12 (that is, assemble into the required finished product). It can be seen that the outer guide sleeve assembly mechanism 8 realizes efficient and precise assembly of the headrest frame 1 and the outer guide sleeve 13 through various designs such as height adjustment, pre-pressing and fixing, and synchronous tightening, effectively ensuring assembly quality and production efficiency.
[0085] The sliding assembly 84 also includes: an assembly motor 841 and a material moving plate 842. The frame 2 is provided with a lead screw 25 connected to the output end of the assembly motor 841. The bottom of the material moving plate 842 is formed with a movable block 843, and the movable block 843 is movably mounted on the lead screw 25; a guide block 844 and a guide rail 845. The guide rail 845 is installed on the frame 2 and is arranged parallel to the lead screw 25. The guide block 844 is connected to the material moving plate 842 and is movably engaged with the guide rail 845; a positioning cylinder 846 is connected to the material moving plate 84 2, the output end of the positioning cylinder 846 is connected to a buffer plate 846a, and the buffer plate 846a is provided with a positioning seat 847 for pre-movably pressing against the side wall of the headrest frame 1; a fixed seat 848 is connected to the material moving plate 842, and the material moving module 80 also includes a positioning rod 800 and a buffer block 801, and the top of the buffer block 801 is movably hinged to the fixing seat 848; the positioning rod 800 is movably arranged in the fixing seat 848 and passes through the buffer block 801, and is used to movably press against the end of the headrest support rod 10.
[0086] Further, if Figures 7 to 9 As shown, after the outer guide sleeve 13 and the semi-finished product to be assembled are placed in place, the assembly motor 841 can be turned on to drive the screw 25 to rotate, and the rotational motion of the screw 25 is converted into the linear motion of the material moving plate 842, so that the material moving plate 842 can quickly approach the contour seat 82 along the axis direction of the screw 25. In this process, the cooperation between the guide rail 845 and the guide block 844 effectively ensures that the movement of the material moving plate 842 is smooth and without deviation, thereby providing a guarantee for the assembly accuracy and quality; it should be noted that in the process of the material moving plate 842 approaching the contour seat 82, the overall moving speed is relatively fast, so as to save the displacement time of the feed. After approaching the contour seat 82, the above-mentioned follower rod 84 0 can be movably pressed against the headrest frame 1, and the follower rod 840 is hinged to the fixing seat 848, so that the follower rod 840 can simultaneously play the role of buffering and pressing against the headrest frame 1; not only that, the positioning rod 800 can be pressed against the end of the headrest support rod 10 in advance, so that the material moving module 80 can smoothly drive the outer guide sleeve 13 to sleeve the headrest support rod 10 and gradually approach the headrest frame 1, which plays a guiding and limiting role during the assembly operation, ensuring that the outer guide sleeve 13 can be accurately assembled into the headrest frame 1; at the moment when the outer guide sleeve 13 and the headrest frame 1 are movably pressed against each other, that is, during assembly, the positioning cylinder 846 drives the buffer plate 846a to gradually move in the direction away from the contour seat 82, such as Figure 8 As shown, since the top of the buffer block 801 is movably hinged to the fixed seat 848, and the buffer block 801 is located on the side of the material shifting module 80 away from the contour seat 82, the buffer plate 846a cooperates with the synchronous movement of the buffer block 801, so that the outer guide sleeve 13 flexibly crosses the auxiliary block 90 and is inserted into the headrest frame 1 and pressed against the steel wire 12. In general, the overall structure can not only realize the rapid arrival of the outer guide sleeve 13 to be assembled at the assembly position, but also complete the operation process of flexible and stable clamping assembly of the outer guide sleeve 13 and the semi-finished product through the cooperation of the buffer plate 846a and the buffer block 801, under the complementary effect of the auxiliary block 90, while ensuring the fluency and accuracy of the overall assembly process, but also significantly improves the production efficiency and product quality.
[0087] The unloading mechanism 9 includes: a horizontal linear guide rail 91, which is arranged on the frame 2, and the output end of the horizontal linear guide rail 91 is connected to the vertical linear guide rail 910; a guide sleeve 92 and a unloading cylinder 93, the output end of the vertical linear guide rail 910 is connected to the mounting plate 910a, and a guide column 821 is arranged at the periphery of the contour seat 82, and the guide sleeve 92 is connected to the mounting plate 910a and movably sleeved on the guide column 821; the unloading cylinder 93 is connected to the mounting plate 910a and is used to grab the headrest frame 1; the positioning cylinder 94 is connected to the mounting plate 910a, and the output end of the positioning cylinder 94 is connected to the auxiliary block 90, and the side wall of the auxiliary block 90 is formed with a protrusion 900, and the protrusion 900 is formed with a guiding inclined surface 900a; a conveyor belt 95, which is arranged on the frame 2, and the conveyor belt 95 is used to move the assembled products to the outside of the frame 2.
[0088] like Figures 7 to 9 As shown, it should be noted that, during the assembly process of the outer guide sleeve 13 and the semi-finished product, the horizontal linear guide rail 91 cooperates with the vertical linear guide rail 910 to move the mounting plate 910a to the top of the semi-finished product. With the driving of the vertical linear guide rail 910, the unloading cylinder 93 (with the same structure and principle as the unloading clamp) can directly extend into the headrest frame 1 and grab it. In other words, the unloading cylinder 93 can not only play a fixing effect during assembly, but also unload the finished product as soon as the assembly is completed, so as to facilitate the subsequent assembly of the semi-finished product and the outer guide sleeve 13. The guide sleeve 13 is used for loading and assembly, which greatly shortens the cycle time, reduces unnecessary waiting time and material transfer time, and improves the overall operating efficiency of the equipment; at the same time, the position of the auxiliary block 90 is flexibly adjusted by the positioning cylinder 94, so that the protrusion 900 and the guiding slope 900a on the auxiliary block 90 can effectively guide the end of the outer guide sleeve 13 to cross and be movably inserted into the headrest frame 1, ensuring the smoothness and accuracy of assembly, and also enabling the structure to adapt to headrest frames 1 of different shapes and sizes, thereby improving the versatility and adaptability of the equipment. After the finished product is assembled, the unloading cylinder 93 cooperates with the horizontal linear guide rail 91 and the vertical linear guide rail 910 to place the finished product on the conveyor belt 95, thereby completing the unloading function of the finished product.
[0089] The support rod assembly mechanism 4 includes: a linear guide rail 40, which is arranged on the frame 2, and the output end of the linear guide rail 40 is connected to a guide plate 400 perpendicular to its moving direction. The positioning mechanism 3 includes an assembly seat 30 and a clamping cylinder 31. The assembly seat 30 is used to position the headrest frame 1 to be assembled, and is movably clamped by the clamping cylinder 31. The guide plate 400 can be aligned with the assembly seat 30 when moving with the linear guide rail 40; a pushing cylinder 41 and a pushing block 42, which are arranged on the guide plate 400, and the output end of the pushing cylinder 41 is connected to a guide frame 410, and a limiting groove 410a is formed on the guide frame 410, and the headrest support rod 10 is placed in the limiting groove 410a; one end of the pushing block 42 is used to insert the headrest support rod 10 into the headrest frame 1, and a buffer spring 420 is connected between the other end and the output end of the pushing cylinder 41.
[0090] like Fig.10 As shown, before the assembly equipment starts, the headrest support rod 10 can be oiled by an oiling mechanism (not shown in the figure) to ensure smoothness when the headrest support rod 10 is subsequently inserted into the headrest frame 1; when the headrest support rod 10 is placed in the limiting groove 410a of the guide frame 410, the design of the limiting groove 410a ensures the accurate positioning of the headrest support rod 10 and avoids deviation during the pushing process; as the linear guide 40 drives the headrest support rod 10 to move from one side of the frame 2 to a position aligned with the assembly seat 30, the pressing cylinder 31 presses the headrest to be assembled The frame 1 is movably pressed in the assembly seat 30, which ensures the stability during the assembly process and avoids assembly errors caused by vibration or movement of the headrest frame 1. The headrest support rod 10 can be pushed into the headrest frame 1 in the assembly seat 30 by using the pushing cylinder 41 through the movement of the pushing block 42. In this process, the buffer spring 420 connected between the output end of the pushing cylinder 41 and the pushing block 42 is used to effectively reduce the impact force during the pushing process under the action of elasticity, thereby protecting the headrest support rod 10 and the headrest frame 1 from damage and extending the service life of the equipment.
[0091] The unlocking rod assembly mechanism 5 includes: a positioning block 50, which is arranged on the frame 2. The positioning block 50 is provided with a guide wheel 51 and a placement groove 52 with an opening facing one side. The guide wheel 51 is movable at the bottom of the placement groove 52 to guide the unlocking rod 11 in the placement groove 52 to move out of the positioning block 50 and be movably inserted into the headrest frame 1; a spring clamping plate 53, which is located on one side of the positioning block 50. The bottom of the spring clamping plate 53 is connected to a lifting cylinder 54, so that the spring clamping plate 53 can be movably pressed against the open end of the placement groove 52; a moving block 55 and a displacement cylinder 56, the moving block 55 is connected to the output end of the displacement cylinder 56, and a push block 550 and a traction block 551 are connected to the moving block 55, and the push block 550 is movably inserted into the placement groove 52; a traction rail 26 is provided on the frame 2, and the traction block 551 is movably connected to the traction rail 26.
[0092] like Figure 10 to Figure 11 As shown, the unlocking rod 11 needs to be inserted into the headrest frame 1 from one side of the headrest frame 1, so when the worker or the manipulator places the unlocking rod 11 to be assembled into the placement groove 52, the lifting cylinder 54 can drive the spring clamping plate 53 to lift and abut against the opening on the side of the placement groove 52, ensuring the stability of the unlocking rod 11 in the placement groove 52, avoiding its deviation or even falling off, which affects the smoothness and accuracy of assembly; as the displacement cylinder 56 pulls the moving block 55 closer to the assembly seat 30, the push block 550 gradually extends into the placement groove. 52 is used to push the unlocking rod 11 into the headrest frame 1 and against the headrest support rod 10 (that is, the assembly process of the semi-finished product is realized). During this process, the rolling of the guide wheel 51 reduces the friction and resistance of the unlocking rod 11 during the insertion process, realizes the flexible assembly of the two, and avoids the damage caused by rigid collision during assembly; at the same time, under the cooperation of the traction block 551 and the traction rail 26, it further guides and limits the push block 550 to push the unlocking rod 11 for assembly, thereby ensuring the accuracy and assembly quality of the semi-finished product after assembly.
[0093] Preferably, in this embodiment, the above-mentioned horizontal linear guide rail 91 and vertical linear guide rail 910 can also be arranged in the first assembly area 20 to cooperate with the gripper cylinder to complete the grasping of the semi-finished product, and then move the semi-finished product to the storage table 64 in the second assembly area 21, thereby reducing the labor intensity during manual handling and position conversion, improving work efficiency, and avoiding collision and damage of the semi-finished product during transportation.
[0094] The technical solution adopted by the present invention to solve its technical problem is to further propose an integrated assembly device for the automobile headrest frame 1, including the following structures: a support rod assembly mechanism 4 and an unlocking rod assembly mechanism 5 located in the first assembly area 20, the support rod assembly mechanism 4 can flexibly insert the oiled headrest support rod 10 into the headrest frame 1, and form a semi-finished product when the unlocking rod assembly mechanism 5 pushes the unlocking rod 11 into the headrest frame 1 and presses against the headrest support rod 10; a storage table 64 located in the second assembly area 21 and having an initial position and an assembly position, which is in the initial position The storage table 64 is used to receive the semi-finished product after assembly, and when it is switched to the assembly position, the steel wire 12 can be assembled on the semi-finished product, and the outer guide sleeve 13 is fixed in the outer guide sleeve mold 621 on the storage table 64 at the same time; the clamping member 70 and the adjusting component 71, the adjusting component 71 is movably inserted in the clamping member 70, and a picking cylinder 710 is provided on the adjusting component 71, and the picking cylinder 710 can synchronously grab the outer guide sleeve 13 when the clamping member 70 clamps the semi-finished product, and when the adjusting component 71 moves relative to the clamping member 70, the outer guide sleeve 13 is driven The picking cylinder 710 moves closer to or farther from the clamping member 70 to adjust the relative position and distance between the outer guide sleeve 13 and the semi-finished product; the pre-pressing block 810, the unloading mechanism 9 and the outer guide sleeve assembly mechanism 8 are located in the third assembly area 22. The pre-pressing block 810 can be extended and retracted relative to the frame 2. The pre-pressing block 810 is used to press and fix the headrest support rod 10 on the semi-finished product to be assembled; the unloading mechanism 9 is provided with a unloading cylinder 93 and an auxiliary block 90, and a convex block 900 with a guiding inclined surface 900a is formed on the auxiliary block 90; the outer guide sleeve assembly mechanism 8 is provided with A buffer block 801 and a positioning rod 800 are provided; when the unloading cylinder 93 grabs the semi-finished product, and when the auxiliary block 90 abuts against the top wall of the headrest frame 1, the pre-pressing block 810 can move away from the headrest support rod 10 and shrink into the frame 2, so that the outer guide sleeve assembly mechanism 8 pushes the positioning rod 800 to abut against the headrest support rod 10 in advance, so as to assist the outer guide sleeve 13 on the buffer block 801 to cross the protrusion 900 in the specified direction and snap-fit tightly onto the steel wire 12 in the headrest frame 1, and directly transfer the assembled finished product to the desired position for storage through the unloading cylinder 93.
[0095] The present embodiment is mainly for realizing the assembly operation of sequentially assembling the headrest support rod 10, the unlocking rod 11 and the outer guide sleeve 13 in the headrest frame 1. Specifically, the worker or the manipulator first applies oil to the headrest support rod 10, which helps to reduce the friction between the moving parts, prolong the service life of the product, and also ensure the smoothness of the subsequent assembly process; the oiled headrest support rod 10 is inserted into the headrest frame 1 by the support rod assembly mechanism 4; then the unlocking rod 11 is pushed into the interior of the headrest frame 1 by the unlocking rod assembly mechanism 5, so that it presses against the installed The headrest support rod 10 is assembled to form a semi-finished product for preliminary assembly; the semi-finished product to be assembled is sent to the storage table 64 located at the initial position, and the storage table 64 can be switched to the assembly position so that the worker or the manipulator can assemble the steel wire 12 to the semi-finished product. When the outer guide sleeve 13 to be assembled is synchronously placed in the outer guide sleeve mold 621, the next assembly step can be prepared; and in the subsequent process in the second assembly area 21, the gripper 70 is mainly responsible for grabbing the semi-finished product, and synchronously with the pick-up cylinder 710 on the adjustment component 71 Grab the outer guide sleeve 13, and use the adjustment component 71 to adjust the position of the picking cylinder 710 relative to the clamping member 70, thereby changing the relative distance between the outer guide sleeve 13 and the semi-finished product to adapt to different assembly requirements, which is conducive to improving the flexibility of the equipment and adapting to the assembly of products of different specifications; after the semi-finished product and the outer guide sleeve 13 arrive at the third assembly area 22, the pre-pressing block 810 can pre-press and fix the headrest support rod 10, and at the same time, the unloading cylinder 93 of the unloading mechanism 9 directly grabs the semi-finished product to ensure the stability of the assembly process At the same time, the finished product can be unloaded as soon as possible after assembly, saving assembly cycle time; when the protrusion 900 on the auxiliary block 90 is synchronously pressed on one side of the end of the headrest frame 1, the pre-pressing block 810 releases the headrest support rod 10, and the outer guide sleeve assembly mechanism 8 accurately assembles the outer guide sleeve 13 into the headrest frame 1 and presses against the steel wire 12 (that is, assembles it into the required finished product) through the positioning rod 800 and the buffer block 801, and then transfers the assembled finished product to the designated position for storage through the unloading cylinder 93. The entire assembly process of the equipment has a high degree of automation. Through pre-pressing and precise guidance, the flexible assembly of the outer guide sleeve 13 and the semi-finished product is realized, while ensuring the accurate docking of the various components during the assembly process, and improving the quality of the assembled product. Preferably, after the assembly of the finished product is completed, the quality of the assembled finished product can be further inspected by a detection camera to facilitate the screening of defective products.
