Description

Technical Field

[0001] The present invention relates to the technical field of buffer assembly equipment, and in particular to an automatic assembly mechanism for a buffer spring. Background Art

[0002] The main purpose of the buffer is to buffer the load impact in the machine equipment, avoid collision damage, eliminate noise, increase the cycle speed, improve product quality, etc.; wherein, the existing buffer is assembled from the buffer base 1001, the pulley 1003, the slider component 1005, the cylinder 1007, the spring 1009 and other parts. In the assembly process of the buffer, the pulley 1003 is assembled on the positioning column 1002 of the buffer base 1001, the slider component 100 is assembled on the slide rail 1004 of the buffer base 1001, the cylinder 1007 is assembled in the cylinder placement groove 1006 and the spring 1009 is assembled in the spring placement groove 1008 (such as Figure 10-11 The assembly of the buffer is completed.

[0003] Among them, in the process of assembling the spring 1009, according to the different types of buffers to be assembled, the spring 1009 of corresponding shape needs to be assembled. The shape of the spring 1009 is divided into "U" shape (such as Figure 10 as shown) and "I" shape (as Figure 11 As shown); wherein, a second slot 10091 is formed on the buffer base 1001, and a third slot 10092 is formed on the slider component 1005. When the "U"-shaped spring 1009 is assembled in the spring placement slot 1008, one end of the "U"-shaped spring 1009 is inserted into the second slot 10091, and the other end is inserted into the third slot 10092. The bent portion of the "U"-shaped spring 1009 is wound around the pulley 1003, thus completing the assembly of the "U"-shaped spring 1009. In addition, a fourth slot 10093 is also formed on the buffer base 1001. When assembling the "I"-shaped spring 1009, one end of the "I"-shaped spring 1009 is inserted into the third slot 10092, and the other end is inserted into the fourth slot 10093. The "I"-shaped spring 1009 will not be wound around the pulley 1003.

[0004] However, existing equipment for assembling buffer springs can only load and assemble "I"-shaped springs, and thus can only assemble one type of buffer. When assembling other types of buffers, other equipment capable of assembling and loading "U"-shaped springs is required. The same equipment cannot load and assemble springs of different shapes, increasing the production cost of the buffer. Therefore, an automatic assembly mechanism for buffer springs is proposed to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic assembly mechanism for a buffer spring in view of the shortcomings of the prior art, so as to solve the technical problem that the existing equipment for assembling buffer springs cannot load and assemble springs of different shapes.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A buffer spring automatic assembly mechanism comprises a machine table and a turntable arranged on the machine table for horizontal intermittent rotation, the turntable is equipped with a plurality of assembly position jigs arranged in an array around its rotation center point; it also comprises a spring material distribution mechanism for continuously and one by one transporting the springs, the spring material distribution mechanism is provided with a material distribution plate which can be moved horizontally, the material distribution plate is provided with a material receiving groove adapted to the spring, and it also comprises a support plate and a support block arranged on the support plate, the top of the support block is formed with a material receiving groove for accommodating the spring, and the side of the support block is provided with a pushing component for pushing the spring placed in the material receiving groove to a material taking position in the material receiving groove; a third support frame is provided on the machine table, the third support frame is provided with a movable plate which can be moved horizontally and up and down, the movable plate is provided with a first material grabbing manipulator and a second material grabbing manipulator which are arranged with a clamping end facing downwards and are used to clamp the two ends of the spring respectively;

[0008] The second material-grabbing manipulator can swing on the movable plate with the vertical direction as the axis. The movable plate is also equipped with a movable seat that can move laterally toward or away from the second material-grabbing manipulator. The first material-grabbing manipulator is installed on the movable seat. The swing of the second material-grabbing manipulator cooperates with the lateral movement of the first material-grabbing manipulator to apply force to the spring to deform it into a "U" shape.

[0009] The machine is also provided with a pressing assembly component placed beside the turntable and used for pressing and assembling the bent portion of the "U"-shaped spring onto the roller.

[0010] The beneficial effects of the present invention are as follows: when you want to assemble the springs, operate the spring dividing mechanism, place a spring in the receiving trough, and then control the dividing plate to move horizontally on the spring dividing mechanism, so that the spring placed in the receiving trough is transported out of the spring dividing mechanism, and transported to the initial end of the receiving trough and the material storage trough for connection, and then operate the pushing component to push the spring to the material taking position in the material storage trough.

[0011] The length of the "U"-shaped spring is greater than that of the "I"-shaped spring. When the "U"-shaped spring needs to be assembled, a uniformly longer spring is placed on the spring dividing mechanism, and the longer spring is transported and pushed. When the longer spring is placed in the designated material picking position, the movable plate is controlled to move downward, so that the first grabbing manipulator and the second grabbing manipulator respectively clamp the two ends of the longer spring, and then the movable plate is controlled to reset upward to achieve clamping of the spring; after controlling the second grabbing manipulator to swing 180 degrees clockwise around the vertical axis, the movable seat is controlled to move laterally on the movable plate toward the second grabbing manipulator, thereby bringing the first grabbing manipulator close to the second grabbing manipulator, applying force to the spring to deform it into a "U" shape, and finally controlling the movable plate to move laterally and downward, assembling the "U"-shaped spring into the spring placement slot on the buffer base, and one end of the "U"-shaped spring is clamped in the second clamping slot, and the other end is clamped in the third clamping slot, and the bent portion of the "U"-shaped spring is placed outside the spring placement slot.

[0012] When it is necessary to assemble the "I"-shaped spring, a uniformly shorter spring is placed on the spring dividing mechanism, and the shorter spring is transported and pushed. When the shorter spring is placed in the designated material picking position, the movable plate is controlled to move downward, so that the first grabbing manipulator and the second grabbing manipulator respectively clamp the two ends of the shorter spring, and then the movable plate is controlled to reset upward to achieve the clamping of the spring; there is no need to control the second grabbing manipulator to swing, and the movable plate is directly controlled to move horizontally and downward to assemble the "I"-shaped spring (that is, the shorter spring) into the spring placement slot on the buffer base, and one end of the "I"-shaped spring is clamped into the third clamping slot, and the other end is clamped into the fourth clamping slot, thereby realizing the assembly of buffers of different models.

[0013] After inserting the two ends of the "U"-shaped spring into the second and third slots respectively, the turntable is driven to rotate a specified angle, driving the buffer base with the "U"-shaped spring with the bent portion placed outside the spring placement slot to align with the press assembly component. In addition, the next buffer base without an assembled spring is placed at the end of the horizontal movable track of the movable plate. The press assembly component is operated to pull the bent portion of the "U"-shaped spring to the specified position, and then press the bent portion until it is wound on the pulley. When assembling the "I"-shaped spring, it can be directly assembled into the spring placement slot without the need for the press assembly process of the press assembly component.

[0014] The present invention automatically assembles "U"-shaped springs through the cooperation of a swinging second grabbing manipulator, a transversely movable first grabbing manipulator and a press assembly component. At the same time, it can also assemble "I"-shaped springs, thereby realizing the assembly of different types of buffers on the same equipment, greatly improving the efficiency of buffer production.

[0030] The following is a detailed description of an automatic assembly mechanism for a buffer spring according to the present invention with reference to the accompanying drawings.

[0031] like Figure 1 As shown, an embodiment of an automatic assembly mechanism for a buffer spring of the present invention includes a machine table 102 and a turntable 103 horizontally rotatably arranged on the machine table 102, the turntable 103 rotates intermittently, and the turntable 103 is equipped with a plurality of assembly position jigs 105 arranged in an array around its rotation center point, and the assembly position jigs 105 are workstations for assembling the buffer; the turntable 103 drives the assembly position jig 105 to rotate intermittently, and cooperates with a loading mechanism for loading the buffer components (i.e., the buffer base 1001, the pulley 1003, the slider component 1005, the cylinder 1007, the spring 1009, etc.), and places the various components of the buffer on the same assembly position jig 105 in sequence according to the assembly process for assembly processing.

[0032] In order to enable the turntable 103 to automatically rotate intermittently on the machine 102, the machine 102 is equipped with an intermittent driving component 104 for driving the turntable 103 to rotate, and the intermittent driving component 104 is operated to drive the turntable 103 to rotate intermittently; specifically, after the turntable 103 rotates to drive one of the assembly position jigs 105 to align with the buffer base loading mechanism (not shown in the figure), the buffer base loading mechanism is operated to load the buffer base 1001 onto the assembly position jig 105, and then the turntable 103 is driven to rotate a specified angle again, and the assembly position jig 105 with the buffer base 1001 is rotated to the alignment pulley assembly mechanism (not shown in the figure). At the same time, the next assembly position jig 105 without the buffer base 1001 is rotated to the alignment pulley assembly mechanism (not shown in the figure). The assembly fixture 105 of the buffer base 1001 is driven to align with the buffer base loading mechanism (not shown in the figure), and the pulley assembly mechanism (not shown in the figure) and the buffer base loading mechanism (not shown in the figure) are operated at the same time. The pulley assembly mechanism (not shown in the figure) assembles the pulley 1003 on the positioning column 102 of the buffer base 1001. After the pulley 1003 is assembled, the turntable 103 is driven again to rotate a specified angle, driving the buffer base 1001 assembled with the pulley 1003 to align with the slider component assembly mechanism (not shown in the figure), and the slider component assembly mechanism (not shown in the figure) is operated to load and assemble the slider component 1005 onto the slide rail 1004 of the buffer base 1001 (as shown in the figure). Figure 10 1006 on the buffer base 1001); then the turntable 103 is driven to rotate to a specified angle, and the buffer base 1001 equipped with the pulley 1003 and the slider component 1005 is driven to align with the cylinder assembly mechanism (not shown in the figure); the cylinder assembly mechanism (not shown in the figure) is operated to automatically load and assemble the cylinder 1007, so that the cylinder 1007 is assembled in the cylinder placement groove 1006 on the buffer base 1001; then the turntable 103 is driven to rotate to a specified angle, and the buffer base 1001 equipped with the pulley 1003, the slider component 1005 and the cylinder 1007 is driven to align with the assembly position of the spring automatic assembly mechanism; the spring automatic assembly mechanism is operated to assemble the spring 1009 in the spring placement groove 1008 on the buffer base 1001, thus completing the assembly of the buffer. The above is the entire process of assembling a buffer. While assembling one of the buffers placed on the assembly position jig 105, the buffers placed on the next assembly position jig 105 are also being assembled in sequence. The intermittent drive component 104 is a prior art. In practice, a servo motor assembly can be used, or a structure in which a missing gear drives all gears to intermittently rotate can be used to drive the turntable 103 to intermittently rotate. Details will not be given here.

[0033] Among them, when assembling the spring 1009, according to the different types of buffers to be assembled, the spring 1009 of the corresponding type needs to be assembled. The types of the spring 1009 are divided into "U" shapes (such as Figure 10 as shown) and "I" shape (as Figure 11 ); wherein, a second slot 10091 is formed on the buffer base 1001, and a third slot 10092 is formed on the slider component 1005. When the "U"-shaped spring 1009 is assembled in the spring placement slot 1008, one end of the "U"-shaped spring 1009 is inserted into the second slot 10091, and the other end is inserted into the third slot 10092. The bent portion of the "U"-shaped spring 1009 is wound around the pulley 1003, thus completing the assembly of the "U"-shaped spring 1009. In addition, a fourth slot 10093 is also formed on the buffer base 1001. When assembling the "I"-shaped spring 1009, one end of the "I"-shaped spring 1009 is inserted into the third slot 10092, and the other end is inserted into the fourth slot 10093. The "I"-shaped spring 1009 will not be wound around the pulley 1003. Buffers of different models are assembled by assembling springs 1009 of different shapes. After the assembly is completed, subsequent testing and discharging processes are carried out.

[0034] like Figure 2-4 As shown, the present spring automatic assembly mechanism also includes a spring dividing mechanism 61 for continuously and one by one transporting the springs 1009, and the spring dividing mechanism 61 is provided with a dividing plate 6106 that can move horizontally, and the dividing plate 6106 is provided with a receiving groove 6107 adapted to the spring 1009; when the receiving groove 6107 on the dividing plate 6106 is placed in the spring dividing mechanism 61, the spring dividing mechanism 61 is operated to place a spring 1009 in the receiving groove 6107, and then the dividing plate 6106 is controlled to move horizontally on the spring dividing mechanism 61, so that the spring 1009 placed in the receiving groove 6107 is transported out of the spring dividing mechanism 61 and transported to a designated pushing position, and then pushed to a designated handling position for loading and assembly processing. By setting the spring dividing mechanism 61 and the dividing plate 6106, automatic feeding processing of the spring 1009 is realized.

[0035] In this embodiment, the spring automatic assembly mechanism also includes a support plate 62 and a support block 63 arranged on the support plate 62. A material receiving groove 631 for accommodating the spring 1009 is formed on the top of the support block 63. A pushing component 64 for pushing the spring 1009 placed in the receiving groove 6107 into the material receiving groove 631 is provided on the side of the support block 63. A stop block 632 is provided on the support block 63, which is placed at the end of the material receiving groove 631 and is used to block the pushed spring 1009 to the material removal position. By controlling the dividing plate 6106 to move horizontally on the spring dividing mechanism 61, the spring 1009 placed in the receiving groove 6107 is transported to the specified pushing position, the receiving groove 6107 is connected with the initial end of the material storage groove 631, and the pushing component 64 is operated to push the spring 1009 into the material storage groove 631. After its end is pushed to contact the stop block 632, the pushing component 64 can be operated to reset and prepare to push the next spring 1009.

[0036] When the spring 1009 is blocked by the block 632 to the designated material picking position in the material trough 631, in order to transport and assemble the spring 1009 into the spring placement groove 1008 of the buffer base 1001, a third support frame 65 is provided on the machine 102, and the third support frame 65 is provided with a movable plate 66 that can move horizontally and up and down. The movable plate 66 is equipped with a first grabbing robot 68 and a second grabbing robot 69 with the clamping end facing downward and used to clamp the two ends of the spring 1009 respectively. The second grabbing robot 69 can swing with the vertical direction as the axis. The movable plate 66 is also equipped with a movable seat 612 that can move horizontally toward or away from the second grabbing robot 69, and the first grabbing robot 68 is installed on the movable seat 612.

[0037] The length of the "U"-shaped spring 1009 is greater than that of the "I"-shaped spring 1009. When the "U"-shaped spring 1009 needs to be assembled, the longer spring 1009 is placed on the spring distributing mechanism 61, and the longer spring 1009 is transported and pushed. When the longer spring 1009 is placed in the designated material-picking position, the movable plate 66 is controlled to move downward so that the first grabbing manipulator 68 and the second grabbing manipulator 69 respectively clamp the two ends of the longer spring 1009, and then the movable plate 66 is controlled to reset upward to realize the clamping of the spring 1009; the second grabbing manipulator 69 is controlled to move clockwise (with the length of the "U"-shaped spring 1009) around the vertical axis. Figure 4 After swinging 180 degrees (based on the reference), the movable seat 612 is controlled to move laterally on the movable plate 66 toward the second material grabbing manipulator 69, thereby bringing the first material grabbing manipulator 68 close to the second material grabbing manipulator 69, and applying force to the spring 1009 to deform it into a "U" shape (such as Figure 5As shown), finally, the movable plate 66 is controlled to move laterally and downwardly, and the "U"-shaped spring 1009 is assembled into the spring placement groove 1008 on the buffer base 1001, and one end of the "U"-shaped spring 1009 is inserted into the second slot 10091, and the other end is inserted into the third slot 10092. When it is necessary to assemble the "I"-shaped spring 1009, the uniformly shorter spring 1009 is placed on the spring distributing mechanism 61, and the shorter spring 1009 is transported and pushed. When the shorter spring 1009 is placed in the designated material picking position, the movable plate 66 is controlled to move downward, so that the first grabbing manipulator 68 and the second grabbing manipulator 69 respectively clamp the two ends of the shorter spring 1009, and then the movable plate 66 is controlled to reset upward to achieve the clamping of the spring 1009; there is no need to control the second grabbing manipulator 69 to swing, and the movable plate 66 is directly controlled to move horizontally and downward, and the "I"-shaped spring 1009 (that is, the shorter spring 1009) is assembled into the spring placement groove 1008 on the buffer base 1001, and one end of the "I"-shaped spring 1009 is clamped into the third clamping groove 10092, and the other end is clamped into the fourth clamping groove 10093, thereby realizing the assembly of buffers of different models.

[0038] In order to make the second material grabbing manipulator 69 swing on the movable plate 66, a second fixed block 614 with a cavity formed inside is provided on the movable plate 66. An axially vertically arranged rotating shaft 615 is rotatably provided in the cavity of the second fixed block 614. The bottom end of the rotating shaft 615 extends to the outside of the second fixed block 614, and a rotating frame 616 is fixed on the bottom end of the rotating shaft 615. The second material grabbing manipulator 69 is installed on the rotating frame 616. The axis of the rotating shaft 615 deviates from the clamping end of the second material grabbing manipulator 69 in the direction away from the movable plate 66. When the rotating shaft 615 is driven clockwise (with a rotation angle of 0.01), the material grabbing manipulator 69 is moved away from the movable plate 66. Figure 4 After rotating 180 degrees (based on the reference), the clamping end of the second material-grabbing robot 69 will swing 180 degrees around the axis of the rotating shaft 615, thereby bending one end of the spring 1009 180 degrees, and then controlling the first material-grabbing robot 68 to approach the second material-grabbing robot 69, applying force to the spring 1009 to deform it into a "U" shape.

[0039] In addition, after the two ends of the "U"-shaped spring 1009 are respectively inserted into the second slot 10091 and the third slot 10092, the bent portion is placed outside the spring placement slot 1008 and cannot be automatically assembled with the pulley 1003. In order to realize the assembly of the bent portion of the "U"-shaped spring 1009 with the pulley 1003, the machine 102 is further provided with a pressing assembly component 7 which is placed beside the turntable 103 and is used to press the bent portion of the "U"-shaped spring 1009 to be assembled onto the pulley 1003; the two ends of the "U"-shaped spring 1009 are respectively inserted into the second slot 10091 and the third slot 10092. After being inserted into the second and third slots 10091 and 10092, the rotary disk 103 is driven to rotate a specified angle, driving the buffer base 1001 equipped with a "U"-shaped spring 1009 with its bent portion placed outside the spring placement slot 1008 to align with the pressing assembly component 7. In addition, the next buffer base 1001 without an assembled spring 1009 is placed at the end of the horizontal movable track of the movable plate 66, and the pressing assembly component 7 is operated to pull the bent portion of the "U"-shaped spring 1009 to a specified position, and then press the bent portion until it is wound around the pulley 1003. When assembling the "I"-shaped spring 1009, it can be directly assembled into the spring placement slot 1008 without the pressing assembly process of the pressing assembly component 7, and the pressing assembly component 7 is skipped for the subsequent detection and discharge process.

[0040] Furthermore, the spring distribution mechanism 61 also includes a first support frame 6101 and a guide component 6102 installed on the first support frame 6101 for guiding a plurality of springs 1009 one by one into the receiving trough 6107. A storage frame 6103 for storing the springs 1009 is installed on the top of the first support frame 6101. The bottom of the storage frame 6103 is an inclined surface, and a discharge port connected to the top of the guide component 6102 is provided at the lowest point of the inclined surface. Under the action of the inclined surface set as the bottom of the storage frame 6103, the springs 1009 in the storage frame 6103 fall one by one and automatically from the discharge port into the guide component 6102 for guiding processing, thereby guiding the springs 1009 one by one into the receiving trough 6107, and then controlling the horizontal movement of the distribution plate 6106 to transport one spring 1009 to the alignment material trough 631.

[0041] A fixed plate 6105 is further provided on the first support frame 6101, and a dividing plate 6106 is horizontally slidably arranged on the fixed plate 6105. The fixed plate 6105 is equipped with a first cylinder 6108 for controlling the horizontal sliding of the dividing plate 6106. In addition, an adjustment plate 6104 is movably provided in the storage frame 6103 for adapting the storage frame 6103 to springs 1009 of different lengths. The "U"-shaped springs 1009 or "I"-shaped springs 1009 are assembled as needed, thereby selecting to place longer springs 1009 or shorter springs 1009 in the storage frame 6103. The movable adjustment plate 6104 is then used to adjust the distance between the adjustment plate 6104 and the inner wall of the storage frame 6103, so that when the springs 1009 fall one by one from the discharge port into the guide component 6102, the length direction of the springs 1009 placed in the storage frame 6103 is always kept parallel to the discharge port. A horizontally sliding partition 6109 is provided between the discharge port at the bottom of the storage frame 6103 and the top of the material guiding component 6102. By controlling the different horizontal movements of the partition 6109, the discharge port at the bottom of the storage frame 6103 and the top of the material guiding component 6102 are intermittently connected. During the horizontal movement, the spring 1009 in the storage frame 6103 is pushed to move to prevent blockage.

[0042] Furthermore, the pushing component 64 includes a second support frame 641, on which a movable block 642 is slidingly provided, the sliding direction of which is parallel to the length direction of the material receiving groove 6107, and the movable block 642 is provided with a pushing block 643 for pushing the spring 1009 placed in the material receiving groove 6107 into the material receiving groove 631. First, operate the spring dividing mechanism 61, load a spring 1009 into the receiving groove 6107 of the dividing plate 6106, and then control the dividing plate 6106 to move horizontally on the spring dividing mechanism 61, so that the receiving groove 6107 on the dividing plate 6106 is connected with the initial end of the material receiving groove 631, and finally control the movable block 642 to slide on the second support frame 641, and push the spring 1009 placed in the receiving groove 6107 into the material receiving groove 631 through the pushing block 643, and push it to the end of the material receiving groove 631, so that the end of the spring 1009 can be against the stop block 632, and then carry out the subsequent transportation and assembly processing.

[0043] Additionally, to control the automatic sliding of the movable block 642, a first linear drive module 644 is mounted on the second support frame 641, its length aligned with the sliding direction of the movable block 642. The movable end of the first linear drive module 644 is fixedly mounted on the movable block 642. The first linear drive module 644 is operated to control the sliding of the movable block 642 on the second support frame 641.

[0044] like Figure 6As shown, the first grabbing robot 68 includes a first fixed block 681 arranged on the movable seat 612, and the first fixed block 681 is provided with a pair of sliding members 682 that can slide towards or away from each other, and each sliding member 682 is provided with a clamping block 683 for clamping the end of the spring 1009; by controlling the movable plate 66 to move downward a specified distance, the clamping blocks 683 on both sides are respectively placed on the left and right sides of the end of the spring 1009, and the sliding members 682 are controlled to approach each other, so that the end of the spring 1009 can be clamped by the clamping blocks 683 on both sides.

[0045] In order to control the sliding members 682 to slide closer to or away from each other, a pair of laterally arranged fixed shafts 684 are provided inside the first fixed block 681, and the axial direction of the fixed shaft 684 is perpendicular to the sliding direction of the sliding member 682. An L-shaped rotating member 685 is rotatably provided on each fixed shaft 684, and the L-shaped rotating members 685 on both sides are symmetrically arranged. A connecting groove 686 is provided on the top of each sliding member 682, and one end of the L-shaped rotating members 685 on both sides cross each other, and the other end is placed in the connecting groove 686 of different sliding members 682. By applying an upward or downward force to the intersection ends of the L-shaped rotating parts 685 on both sides at the same time, the L-shaped rotating parts 685 on both sides rotate toward each other on different fixed axes 684. When an upward force is applied to the intersection ends, the ends of the L-shaped rotating parts 685 on both sides placed in the connecting grooves 686 approach each other, thereby driving the sliding parts 682 on both sides to slide closer to each other. Conversely, when a downward force is applied to the intersection ends, the ends of the L-shaped rotating parts 685 on both sides placed in the connecting grooves 686 move away from each other, thereby driving the sliding parts 682 on both sides to slide away from each other.

[0046] To control the L-shaped rotating members 685 on either side from rotating toward each other on different fixed axes 684, a first lifting rod 687 is mounted on the first fixed block 681, allowing it to move vertically. A fixing rod 688 is positioned at the bottom end of the first lifting rod 687, its axis parallel to the axis of the fixed axis 684. The intersecting ends of the L-shaped rotating members 685 on either side are each provided with a recess for accommodating the fixing rod 688, which is positioned within the recesses on both L-shaped rotating members 685. By controlling the first lifting rod 687 to move vertically on the first fixed block 681, the fixing rod 688 simultaneously applies an upward or downward force to the intersecting ends of the L-shaped rotating members 685 on both sides, thereby controlling the clamping blocks 683 on both sides to move closer or further away from each other. Furthermore, a third cylinder 689 with a downwardly directed telescopic rod is mounted on the movable seat 612, with the end of the telescopic rod of the third cylinder 689 fixed to the top of the first lifting rod 687.

[0047] A second lifting rod 6810 that moves up and down is also provided on the first fixed block 681, and a pressing portion 6811 is formed at the bottom end of the second lifting rod 6810 for pressing the end of the spring 1009 to a specified position. In addition, the first grabbing manipulator 68 and the second grabbing manipulator 69 have similar structures, and the second lifting rod 6810 with a pressing portion 6811 is also provided on the second grabbing manipulator 69. When the first grabbing manipulator 68 and the second grabbing manipulator 69 are operated to clamp the two ends of the spring 1009 respectively and move the spring 1009 to align with the spring placement slot 1008 on the buffer base 1001, the first grabbing manipulator 68 and the second grabbing manipulator 69 are controlled to move downward at the same time; when the "U"-shaped spring 1009 is assembled, the two ends of the "U"-shaped spring 1009 are aligned with the second slot 10091 and the third slot 10092 respectively. After moving downward a specified distance, the first grabbing manipulator 68 and the second grabbing manipulator 69 are controlled. The second lifting rod 6810 on the movable seat 612 is simultaneously moved downward, and the pressing portion 6811 on the second lifting rod 6810 presses the two ends of the "U"-shaped spring 1009 into the second and third slots 10091 and 10092 respectively. Similarly, when assembling the "I"-shaped spring 1009, the second lifting rods 6810 on the first and second grabbing manipulators 68 and 69 are controlled to move downward simultaneously, pressing the two ends of the "I"-shaped spring 1009 into the third and fourth slots 10093 respectively. A fourth cylinder 6812 with a downwardly directed telescopic rod is mounted on the movable seat 612, and the end of the telescopic rod of the fourth cylinder 6812 is fixed to the top of the second lifting rod 6810.

[0048] In addition, a first clearance groove 633 is formed on the top of the support block 63, located at the end of the material storage groove 631 and used to provide a gripping position for the material gripping end of the first material grabbing robot 68. A second clearance groove 634 is also formed near the beginning of the material storage groove 631 and provides a gripping position for the material gripping end of the second material grabbing robot 69. The provision of the first clearance groove 633 and the second clearance groove 634 allows the first and second material grabbing robots 68 and 69 to grip the spring 1009 from the left and right sides of the end of the spring 1009, thereby improving the gripping accuracy.

[0049] The first and second clearance grooves 633 and 634 are provided for gripping the longer spring 1009. When a shorter spring 1009 is required, a third clearance groove 635 is formed in the middle of the top of the support block 63 to provide a gripping position for the gripping end of the first gripping manipulator 68. The movable seat 612 is controlled to move toward the second gripping manipulator 69 until the gripping end of the first gripping manipulator 68 is aligned with the third clearance groove 635.

[0050] A first pressing member 620 is fixed to the movable plate 66 for pressing the buffer base 1001 during assembly of the spring 1009. During assembly of the spring 1009, the first pressing member 620 first presses the buffer base 1001, and then the ends of the spring 1009 are pressed into designated slots. The first pressing member 620 prevents the buffer base 1001 from shifting.

[0051] To enable the movable plate 66 to automatically move laterally and vertically on the third support frame 65, a control component 67 for controlling the lateral and vertical movement of the movable plate 66 is provided on the third support frame 65. The control component 67 includes a second linear drive module 671 mounted and arranged transversely on the third support frame 65. The second linear drive module 671 is provided with a connecting plate 672. By operating the second linear drive module 671, the connecting plate 672 can be controlled to slide laterally on the third support frame 65. The movable plate 66 slides vertically on the connecting plate 672. A second cylinder 673 with a downwardly directed telescopic rod is mounted on the connecting plate 672. The end of the telescopic rod of the second cylinder 673 is fixed to the movable plate 66. The second linear drive module 671 drives the movable plate 66 to move laterally, and the second cylinder 673 controls the movable plate 66 to move vertically and horizontally on the third support frame 65.

[0052] To control the lateral movement of the first material-grabbing robot 68 on the movable plate 66, a fixed frame 610 is provided on the movable plate 66. A screw rod 611 is rotatably mounted within the fixed frame 610, its axial direction aligned with the movement direction of the connecting plate 672. A movable seat 612 is threadedly connected to the screw rod 611. By driving the screw rod 611 to rotate, the screw rod 611 and the movable seat 612 engage with each other, thereby driving the movable seat 612 to move horizontally on the movable plate 66, moving the first material-grabbing robot 68 toward or away from the second material-grabbing robot 69. Furthermore, the fixed frame 610 is equipped with a servo motor 613 for driving the screw rod 611 to rotate.

[0053] like Figure 7As shown, in order to control the rotation of the rotating shaft 615 by 180 degrees, a gear 617 placed in the second fixed block 614 is installed on the rotating shaft 615, and a fifth cylinder 619 with a transversely arranged output shaft is installed on the movable plate 66. A transversely arranged rack 618 is fixed to the end of the telescopic rod of the fifth cylinder 619, and the rack 618 passes through the second fixed block 614 and engages with the gear 617. When the fifth cylinder 619 is operated, the rack 618 moves laterally, thereby driving the gear 617 and the rotating shaft 615 to rotate. After the fifth cylinder 619 rotates to 180 degrees, it stops operating, bends one end of the spring 1009 by 180 degrees, and then controls the first material grabbing robot 68 to move a specified distance toward the second material grabbing robot 69, so that the spring 1009 forms a "U" shape.

[0054] like Figure 8-9 As shown, the pressing assembly component 7 includes a fourth support frame 71 and a lifting plate 72 that is movable up and down on the fourth support frame 71, the lifting plate 72 is provided with a horizontally movable translation plate 75, and the translation plate 75 is provided with a lifting seat 77 that can move up and down; wherein, the lifting seat 77 is provided with an axially vertically arranged sleeve 79, and a pulling column 710 is provided at the bottom end of the sleeve 79 to slide up and down, and the sleeve 79 is sleeved on the outside of the pulling column 710. After the two ends of the "U"-shaped spring 1009 are respectively inserted into the second slot 10091 and the third slot 10092, the turntable 103 is driven to rotate a specified angle, driving the buffer base 1001 equipped with the "U"-shaped spring 1009 with the bent portion placed on the outside of the spring placement slot 1008 to align with the drawing column 710. At this time, the drawing column 710 is aligned with the inner side of the bent portion of the "U"-shaped spring 1009, and the lifting plate 72 is controlled to move downward on the fourth support frame 71, thereby driving the sleeve 79 and the drawing column 710 to move downward together, inserting the drawing column 710 into the inner side of the bent portion of the "U"-shaped spring 1009, and then controlling the translation plate 75 to move away from the "U". The end of the "U"-shaped spring 1009 moves in the direction of the end portion, so that the outer side of the circumference of the drawing column 710 contacts the inner arc surface of the bent portion, pulling the bent portion of the "U"-shaped spring 1009 to move, causing the "U"-shaped spring 1009 to stretch. After the bent portion is pulled to align with the pulley 1003, the lifting seat 77 is controlled to move upward, and the lifting seat 77 moves downward with the sleeve 79, so that the sleeve 79 moves downward on the outer side of the drawing column 710, and the bent portion of the "U"-shaped spring 1009 is pressed downward by the bottom end of the sleeve 79 until the bent portion is wound around the pulley 1003, thus completing the assembly of the bent portion of the "U"-shaped spring 1009.

[0055] After assembly is complete, the control lift seat 77 is reset upward. To allow the material pulling column 710 to return downward on the sleeve 79, an elastic member 711 is provided within the sleeve 79 and positioned above the material pulling column 710 to exert a downward force on the material pulling column 710. As the bent portion of the "U"-shaped spring 1009 is pressed downward at the bottom end of the sleeve 79, the elastic member 711 is compressed. Once the assembly is complete, when the control lift seat 77 is reset upward, the compressed elastic member 711 exerts a downward force on the material pulling column 710, causing it to return downward. The elastic member 711 may be a return spring, a spring, or the like.

[0056] In addition, a second pressing member 74 is fixedly provided on the lifting plate 72 for pressing the two ends of the spring 1009 during the assembly of the bent portion of the spring 1009; after controlling the lifting plate 72 to move downward a specified distance on the fourth support frame 71, the second pressing member 74 presses the two ends of the "U"-shaped spring 1009, which are respectively clamped into the second slot 10091 and the third slot 10092, to prevent the two ends of the "U"-shaped spring 1009 from detaching from the second slot 10091 and the third slot 10092 during the subsequent pulling column 710 pulling the bent portion of the "U"-shaped spring 1009.

[0057] In addition, a limiting groove 712 is formed on the circumferential side of the pulling column 710 for limiting the bent portion of the spring 1009; when the circumferential outer side of the pulling column 710 contacts the inner arc surface of the bent portion of the "U"-shaped spring 1009, the bent portion is placed in the limiting groove 712, and the bent portion is limited by the limiting groove 712 to prevent the bent portion from detaching from the pulling column 710 during the process of pulling the bent portion of the "U"-shaped spring 1009.

[0058] To control the vertical movement of the lifting plate 72 on the fourth support frame 71, a sixth cylinder 73 with a downwardly directed telescopic rod is mounted on the fourth support frame 71, with the end of the telescopic rod of the sixth cylinder 73 fixed to the lifting plate 72. To control the horizontal movement of the translation plate 75 on the lifting plate 72, a seventh cylinder 76 with a telescopic rod axially aligned with the direction of movement of the translation plate 75 is mounted on the lifting plate 72, with the end of the telescopic rod of the seventh cylinder 76 fixed to the translation plate 75. To control the vertical movement of the lifting seat 77 on the translation plate 75, an eighth cylinder 78 with a downwardly directed telescopic rod is mounted on the translation plate 75, with the end of the telescopic rod of the eighth cylinder 78 fixed to the lifting seat 77.

[0059] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
