Description

Technical Field

[0001] This application relates to the field of air block processing technology, and in particular to an automatic assembly device for air block springs. Background Technology

[0002] Currently, in the production process of air blocks, small springs need to be precisely assembled in specific positions. This process is typically used to ensure the reset function of the valve core or sealing structure inside the air block.

[0003] In related technologies, spring assembly often relies on manual operation or semi-automatic equipment. Operators manually insert the springs into the holes of the air block using simple tools. Some automation solutions may only achieve automatic pressing of a single spring. For air blocks that require the assembly of multiple springs, the efficiency improvement is limited, and there is a lack of automatic quality inspection and sorting functions after assembly.

[0004] Regarding the aforementioned technologies, the inventors believe that they have the following drawbacks: existing assembly methods are inefficient, have high labor costs, assembly quality depends on operator proficiency, it is difficult to guarantee product consistency under mass production, and there is a lack of complete online inspection and sorting processes. Summary of the Invention

[0005] To address the issues of low efficiency, poor consistency, and lack of integrated inspection processes in manual spring assembly, this application provides an automatic assembly device for springs used in air blocks.

[0006] The automatic assembly device for springs used in air expansion blocks provided in this application adopts the following technical solution: An automatic assembly device for springs used in air blocks includes a base, on which an intermittently driven drive device is provided. A processing table is connected to the output of the drive device, and several mounting seats are fixedly connected to the surface of the processing table. The base is provided with the following in sequence around the rotation path of the processing table: a loading station, which is provided with a loading mechanism for transferring and positioning the air-inflated block onto the mounting base; Both the first spring assembly station and the second spring assembly station are equipped with a multi-degree-of-freedom drive module and a connecting seat connected to its moving end. The connecting seat is equipped with a gripping actuator and a first fixed cylinder driven by a first linear driver. The drive module is used to drive the gripping actuator and the fixed cylinder to move between the material picking position and the assembly position on the mounting seat below it, so as to complete the gripping and initial assembly of the spring. The secondary fixing station is equipped with a fixing mechanism for finally tightening the springs assembled on the air expansion block; The inspection station is equipped with an inspection mechanism for checking whether the spring assembly is qualified; The receiving station is equipped with a receiving mechanism for removing the assembled air blocks from the mounting base.

[0007] By adopting the above technical solution, the device uses an intermittently driven processing table to carry workpieces sequentially through various functional stations arranged around it, constructing a closed-loop automated assembly line. The feeding mechanism enables automatic feeding; the first and second spring assembly stations sequentially complete the gripping, placement, and preliminary pressing of two springs; the secondary fixing station ensures assembly reliability; the inspection station performs online quality inspection; and the receiving station is responsible for unloading. The entire process greatly reduces manual intervention and significantly improves assembly efficiency, consistency, and automation.

[0008] Preferably, the drive module includes a first support platform fixedly connected to the base, and a first sliding platform fixedly connected to the outer wall of the first support platform. A drive seat is slidably connected to the side of the first sliding platform near the first support platform, and a lifting seat is slidably connected to the drive seat. The connecting seat is fixedly connected to the end of the lifting seat. A second linear driver is fixedly connected to the side of the first support platform near the drive seat. The output shaft of the second linear driver is fixedly connected to the drive seat. A third linear driver is fixedly connected to the drive seat, and the output shaft of the third linear driver is fixedly connected to the lifting seat.

[0009] By adopting the above technical solution, the drive module adopts a structure in which the drive seat is driven to move horizontally along the first sliding table by the second linear driver, and the lifting seat is driven to move vertically along the drive seat by the third linear driver. This realizes the precise and stable movement of the connecting seat and the assembly unit on it in two-dimensional space. The structure is compact and the control is simple and reliable.

[0010] Preferably, the fixing mechanism includes a second support platform fixedly connected to the base, a support frame fixedly connected to the side of the second support platform near the processing table, a fourth linear driver fixedly connected to the support frame, a fixed seat fixedly connected to the output shaft of the fourth linear driver, and a pair of second fixed cylinders symmetrically fixedly connected to the side of the fixed seat away from the fourth linear driver.

[0011] By adopting the above technical solution, the fixing mechanism drives the fixing base and two second fixing cylinders to reciprocate and lift, through the fourth linear actuator. This allows for simultaneous, multiple cyclic pressing of the two springs already pre-installed on the air block. This secondary tightening process effectively eliminates the assembly gap of the springs, ensuring the firmness and stability of the spring installation and improving the final quality of the product.

[0012] Preferably, the detection mechanism includes a third support platform fixedly connected to the base, a connecting frame fixedly connected to the side of the third support platform near the processing table, a detection box fixedly connected to the connecting frame, and a detection probe and a first positioning sensor fixedly connected to the side of the detection box near the processing table.

[0013] By adopting the above technical solution, the inspection mechanism integrates an inspection probe and a positioning sensor, which can automatically trigger image acquisition after the workpiece is in place. By comparing the acquired workpiece image with a pre-stored standard template, automatic visual inspection of the spring assembly status is achieved, quickly and accurately determining whether the product is qualified or not, and providing signal basis for subsequent automatic sorting.

[0014] Preferably, the receiving mechanism includes a fourth support platform fixedly connected to the base, a second sliding platform fixedly connected to the fourth support platform, a fifth linear actuator fixedly connected to the side of the second sliding platform away from the fourth support platform, a sliding seat connected to the output shaft of the fifth linear actuator, a mounting seat slidably connected to the sliding seat, and a sixth linear actuator and a first gripper fixedly connected to the mounting seat.

[0015] By adopting the above technical solution, the receiving mechanism realizes the horizontal movement of the sliding seat and the first gripper through the fifth linear drive, and realizes the vertical lifting of the first gripper through the sixth linear drive, thereby accurately grabbing the finished product on the processing table and moving it out of the mounting seat, freeing up the work position for the next cycle, and realizing the automatic unloading of the product.

[0016] Preferably, a recycling section is provided between the receiving mechanism and the detection mechanism. The recycling section includes at least two slide rails fixedly connected to the base, and the two slide rails point at different angles. The ends of each of the guide slide rails are respectively placed with a qualified product collection box and a non-qualified product collection box.

[0017] By adopting the above technical solution, the recycling section is equipped with two slide rails pointing at different angles, corresponding to the collection paths of qualified and unqualified products, respectively. Based on the judgment results of the testing agency, the receiving mechanism can place the products into the corresponding slide rail inlets, and the products slide into the corresponding collection boxes by gravity, realizing automatic sorting and classification collection after testing.

[0018] Preferably, a toothed plate is fixedly connected to the lower part of the side of the sliding seat near the second sliding platform. A drive gear meshes on the toothed plate. A first drive shaft is fixedly connected to the drive gear. The two ends of the first drive shaft are rotatably connected to the second sliding platform and the base, respectively. A main drive gear is also fixedly connected to the outer wall of the first drive shaft. A secondary drive gear meshes on the main drive gear. A second drive shaft is fixedly connected to the secondary drive gear. One end of the second drive shaft is rotatably connected to the base, and the other end of the second drive shaft is fixedly connected to a guide rail.

[0019] By adopting the above technical solution, this linkage mechanism cleverly transforms the horizontal linear motion of the receiving mechanism's sliding seat into the rotational oscillation of the second drive shaft and guide rail through a toothed plate-gear-transmission shaft system. This allows the oscillation angle of the guide rail to automatically synchronize with the moving position of the sliding seat (i.e., the target collection box), eliminating the need for an additional independent drive for the diversion action, simplifying the structure, reducing costs, and improving the reliability of coordinated actions.

[0020] Preferably, a second positioning sensor is fixedly connected to the upper part of the side of the sliding seat near the second sliding platform, and a plurality of positioning elements cooperating with the second positioning sensor are fixedly connected in the extending direction of the second sliding platform to detect and control the moving position of the first gripper.

[0021] By adopting the above technical solution, the second positioning sensor set on the sliding seat cooperates with the positioning components set at different positions on the second sliding table to accurately detect and control the horizontal movement stroke of the sliding seat, ensuring that the first gripper can accurately stop at the release position corresponding to the qualified or unqualified product, thereby ensuring the accuracy of the diversion action.

[0022] Preferably, the feeding mechanism includes a fifth support platform fixedly connected to the base, a seventh linear driver fixedly connected to the side of the fifth support platform away from the base, a movable stage fixedly connected to the output shaft of the seventh linear driver, the movable stage slidably connected to the fifth support platform, and a baffle fixedly connected to the side of the movable stage near the seventh linear driver.

[0023] By adopting the above technical solution, the loading station uses a seventh linear actuator to drive a movable table with a baffle to extend and retract. The movable table can be used to receive workpieces from the feed channel, and the baffle can block the feed channel outlet when the movable table extends, preventing workpieces from piling up or falling. This structure provides preliminary receiving and positioning functions for automatic loading.

[0024] Preferably, a sixth support platform is provided on one side of the fifth support platform, an eighth linear driver is fixedly connected to the side of the sixth support platform near the fifth support platform, a sliding support is fixedly connected to the output end of the eighth linear driver, a bracket is slidably connected to the sliding support, a second gripper is fixedly connected to the side of the bracket near the base, a ninth linear driver is fixedly connected to the sliding support, and the output shaft of the ninth linear driver is fixedly connected to the sliding support.

[0025] By adopting the above technical solution, this part constitutes the picking and placing robot of the feeding mechanism. The eighth linear drive drives the sliding support and the second gripper to move horizontally, and the ninth linear drive drives the bracket and the second gripper to move vertically up and down, thereby realizing the complete picking and placing action of grabbing the inflatable block from the moving table, then moving it horizontally to the upper part of the processing table mounting base, and finally lowering it for placement, thus completing the key steps of automated feeding.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up an intermittently rotating processing table and a complete workstation layout around it for feeding, dual-station assembly, secondary fixing, inspection, and material collection, the fully automated assembly line operation of the air expansion block spring assembly process was realized, which greatly improved production efficiency and product consistency, and reduced labor costs and labor intensity. 2. Through the recycling unit with sorting function, online automatic detection of assembly quality and automatic sorting and collection of qualified / unqualified products are realized, forming a complete quality closed-loop control and improving the intelligence level of the production line.

[0041] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0042] This application discloses an automatic assembly device for springs used in air expansion blocks, referring to... Figure 1The system includes a base 1, and a processing table 3 is provided in the middle of the upper part of the base 1. The processing table 3 is connected to the top surface of the base 1 through a drive device 2. Several (preferably eight) mounting seats 4 are fixedly connected to the side of the processing table 3 away from the drive device 2. The eight mounting seats 4 are evenly spaced around the surface of the processing table 3. The mounting seats 4 are used to place and limit the air expansion blocks.

[0043] The base 1 is arranged in sequence around the rotation path of the processing table 3 as follows: loading station 11, air block feeding station 17, first spring assembly station 12, second spring assembly station 13, secondary fixing station 14, inspection station 15 and receiving station 16.

[0044] The loading station 11 is equipped with a loading mechanism 5 for transferring and positioning the air blocks onto the mounting base 4; the air block feeding station 17 is equipped with an air block feeding structure 171 for providing air block raw materials to the loading mechanism 5; both the first spring assembly station 12 and the second spring assembly station 13 are equipped with processing equipment for machining springs onto the air blocks; the secondary fixing station 14 is equipped with a fixing mechanism 6 for finally tightening the springs assembled on the air blocks; the inspection station 15 is equipped with an inspection mechanism 7 for checking whether the spring assembly is qualified; and the receiving station 16 is equipped with a receiving mechanism 8 for removing the assembled air blocks from the mounting base 4.

[0045] Therefore, in this embodiment, the preliminary principle achieved is as follows: first, the air block is received and positioned at the loading station 11; then, the springs are installed sequentially at the first spring assembly station 12 and the second spring assembly station 13; then, the final fastening is performed at the secondary fixing station 14; then, the product undergoes a qualification inspection at the inspection station 15; and finally, the finished product is removed at the receiving station 16.

[0046] It should be noted that, Figure 1 The dotted lines and directional arrows shown are for illustrative purposes only and do not actually exist.

[0047] Specifically, refer to Figure 2 The mounting base 4 has a limiting groove 41 that matches the shape of the air block, and symmetrical notches 42 are opened on both side walls (the inner wall where the short diameter is located) of the mounting base 4 to facilitate the subsequent insertion and removal of the air block.

[0048] Reference Figure 3The feeding mechanism 5 includes a fifth support platform 51, a sixth support platform 55, a seventh linear actuator 52, a moving stage 53, an eighth linear actuator 56, a ninth linear actuator 60, a sliding support 57, and a bracket 58. The fifth support platform 51 is fixedly connected to the surface of the base 1. The moving stage 53 and the seventh linear actuator 52 (preferably an electric actuator rod) are both fixedly connected to the side of the fifth support platform 51 away from the base 1. The seventh linear actuator 52 is located on the top surface of the fifth support platform 51 away from the processing table 3, and its output shaft points towards the processing table 3. The moving stage 53 is fixedly connected to the end of the output shaft of the seventh linear actuator 52 and is slidably connected to the surface of the fifth support platform 51. The sixth support platform 55 is located on one side of the fifth support platform 51 and is fixedly connected to the top surface of the base 1. The eighth linear actuator 56 (preferably an electric guide rail) is fixedly connected to the upper part of the sixth support platform 55 near the fifth support platform 51. The sliding support 57 is fixedly connected to the output part of the eighth linear actuator 56. The bracket 58 is fixedly connected to the side of the sliding support 57 near the fifth support platform 51. The ninth linear actuator 60 (preferably an electric actuator rod) is fixedly connected to the side of the sliding support 57 away from the fifth support platform 51. The output shaft of the ninth linear actuator 60 is fixedly connected to the bracket 58. The side of the bracket 58 near the base 1 is fixedly connected to a second gripper 59 (preferably Robotiq 2F-85, capable of automatic gripping) for automatically gripping the air block.

[0049] The air-expanding block feeding structure 171 is located on the side of the fifth support platform 51 away from the sixth support platform 55. The air-expanding block feeding structure 171 includes an inclined slide 1711 with a support seat 1712. It should be noted that the support seat 1712 of the inclined slide 1711 is fixedly connected to the base 1. In addition, the inclined slide 1711 gradually tilts downward towards the side of the fifth support platform 51, so that the air-expanding blocks in the inclined slide 1711 can gradually slide towards the side of the fifth support platform 51 under the action of gravity, reducing energy consumption.

[0050] A baffle 54 is fixedly connected to the side of the corresponding moving platform 53 that is close to the seventh linear actuator 52 and the side that is close to the inclined slide 1711. A protrusion 531 is provided on the side of the moving platform 53 that is away from the inclined slide 1711 to prevent the air block from detaching. Two symmetrically arranged baffles 1713 are fixedly connected to the side of the inclined slide 1711 that is close to the fifth support platform 51. The baffles 1713 abut against the fifth support platform 51. It should be noted that the positions of the two baffles 1713 will not prevent the air block from moving onto the moving platform 53 via the inclined slide 1711.

[0051] Furthermore, the operating principle jointly achieved by the feeding mechanism 5 and the air-expanding block feeding structure 171 is as follows: the air-expanding blocks automatically slide down the inclined slide 1711 under the action of gravity and enter the surface of the moving table 53 through the channel between the two baffle plates 1713. The moving table 53 restricts and positions the air-expanding blocks within a designated area. Subsequently, the seventh linear actuator 52 is activated, driving the moving table 53 and the air-expanding blocks on it to move horizontally to the predetermined feeding station 11. During the movement, the baffle 54 blocks the outlet of the inclined slide 1711, preventing other air-expanding blocks from detaching from the inclined slide 1711.

[0052] Simultaneously, the eighth linear actuator 56 drives the sliding support 57 and the bracket 58 to move, aligning the second gripper 59 with the air block. Then, the ninth linear actuator 60 drives the bracket 58 and the second gripper 59 to descend vertically, allowing the second gripper 59 to grasp the air block already positioned on the moving table 53. After grasping, the ninth linear actuator 60 drives the second gripper 59 to rise, and the eighth linear actuator 56 drives it to move horizontally above the processing table 3. Finally, the ninth linear actuator 60 drives the second gripper 59 to descend again, precisely releasing the air block and positioning it on the mounting base 4 of the processing table 3, completing the automatic loading process.

[0053] Reference Figure 4 and Figure 5 The processing equipment in both the first spring assembly station 12 and the second spring assembly station 13 includes a multi-degree-of-freedom drive module 121, a connecting seat 122, a first fixed cylinder 125, and a first linear actuator 124 (preferably an electric actuator). The drive module 121 includes a first support platform 1211, a first sliding table 1212, a drive seat 1213, a lifting seat 1214, a second linear actuator 1215, and a third linear actuator 1216.

[0054] The first support platform 1211 is disposed in the corresponding first spring assembly station 12 or second spring assembly station 13, and the first support platform 1211 is fixedly connected to the top surface of the base 1. The first sliding platform 1212 is fixedly connected to the upper part of one outer side wall of the first support platform 1211. The second linear actuator 1215 (preferably an electric actuator) is fixedly connected to the upper part of the side of the first support platform 1211 near the processing table 3, and the output shaft of the second linear actuator 1215 points to the processing table 3. The drive seat 1213 is fixedly connected to the output shaft of the second linear actuator 1215. In addition, the drive seat 1213 is simultaneously slidably connected to the side of the first sliding platform 1212 near the first support platform 1211. The lifting seat 1214 is slidably connected to the side of the drive seat 1213 away from the first sliding table 1212. The third linear actuator 1216 (preferably an electric actuator) is fixedly connected to the top surface of the drive seat 1213, and the output shaft of the third linear actuator 1216 is fixedly connected to the lifting seat 1214. Additionally, the connecting seat 122 is fixedly connected to the bottom surface of the lifting seat 1214. A drive gripping actuator 123 (preferably an automatic gripper) is fixedly connected to the bottom surface of the connecting seat 122 away from the processing table 3. A first linear actuator 124 (preferably an electric actuator) is fixedly connected to the top surface of the connecting seat 122 near the processing table 3. The output shaft of the first linear actuator 124 passes through the connecting seat 122 and is fixedly connected to the first fixed cylinder 125. It is important to note that the two first fixed cylinders 125 in the first spring assembly station 12 and the second spring assembly station 13 are symmetrically arranged with the central axis of the connecting seat 122 as the center, thus allowing springs to be installed in different areas of the air block separately.

[0055] A first limiting frame 1217 is fixedly connected to the bottom surface of the first sliding table 1212 and the side near the processing table 3. A tenth linear actuator 1218 (preferably an electric push rod with a self-locking function) is fixedly connected to the top wall of the first limiting frame 1217. The output shaft of the tenth linear actuator 1218 faces the base 1, and a second limiting frame 1219 is fixedly connected to the output shaft. A limiting bracket 1220 adapted to the shape of the air block is fixedly connected to the second limiting frame 1219. Two through holes 1221 are opened on the limiting bracket 1220 to serve as a channel for the first fixed cylinder 125 to pass through, so that the first fixed cylinder 125 can initially install the spring on the air block.

[0056] The operating principle is as follows: When the mounting base 4 with the air inflator moves directly below the limiting frame 1220, the tenth linear actuator 1218 first pushes the limiting frame 1220 downward to limit and fix the air inflator. Then, the drive module 121 (driven by the second linear actuator 1215 and the third linear actuator 1216) drives the connecting base 122, the gripping actuator 123, and the first fixed cylinder 125 to move as a whole to the spring feeding position. The gripping actuator 123 grips a spring. Next, the drive module 121 drives the assembly unit to move as a whole to directly above the air inflator that has moved below the workstation. The gripping actuator 123 performs a release action, initially placing the spring in the predetermined installation position on the air inflator. Subsequently, the gripping actuator 123 resets and is driven by the drive module 121 back to the spring feeding position, ready for the next gripping.

[0057] As the gripping actuator 123 returns and begins its next gripping action, the first linear actuator 124 activates, driving the first fixed cylinder 125 to reciprocate up and down. The first fixed cylinder 125 passes through the corresponding through hole 1221 on the limit bracket 1220, applying axial pressure to the spring that has been initially placed on the air expansion block, completing the final press-in assembly of the spring. Subsequently, the first linear actuator 124 resets, causing the first fixed cylinder 125 to rise and retract.

[0058] Reference Figure 6 The fixing mechanism 6 includes a second support platform 61 fixedly connected to the base 1. A support frame 62 is fixedly connected to the upper part of the second support platform 61 near the processing table 3. A fourth linear actuator 63 (preferably an electric actuator) is fixedly connected to the support frame 62. A fixed seat 64 is fixedly connected to the output shaft of the fourth linear actuator 63. Two second fixed cylinders 65 are symmetrically fixedly connected to the side of the fixed seat 64 away from the fourth linear actuator 63. The positions of the two second fixed cylinders 65 correspond to the positions of the springs on the air block, so that the bottom edge of the second fixed cylinder 65 can contact the spring during the descent of the second fixed cylinder 65.

[0059] The operating principle is as follows: After the air block with the spring initially assembled rotates with the processing table 3 and is precisely positioned directly below the fixed base 64, the fourth linear actuator 63 is activated, driving the fixed base 64 and its two symmetrically arranged second fixed cylinders 65 to reciprocate linearly in the vertical direction. During this process, the bottoms of the two second fixed cylinders 65 are aligned and periodically pressed against the corresponding springs on the air block. Through multiple, symmetrical applications of force, the springs are cyclically pressed together. This process aims to further tighten the springs axially to eliminate assembly gaps, ensure that the springs are installed in place and have a stable and reliable connection, thereby completing the secondary fixation of the springs.

[0060] Reference Figure 7The detection mechanism 7 includes a third support platform 71 fixedly connected to the base 1. A connecting frame 72 is fixedly connected to the upper part of the third support platform 71 near the processing table 3, and a detection box 73 is fixedly connected to its end. A detection probe 74 (preferably an industrial camera) and a first positioning sensor 75 (proximity switch) are fixedly connected to the side of the detection box 73 facing the processing table 3. A controller 76 is provided on the inner wall of the detection box 73, and the controller 76 is communicatively connected to the detection probe 74 and the first positioning sensor 75.

[0061] The detection method is based on the principle of machine vision comparison: During the system initialization phase, the detection probe 74 acquires images of a qualified inflatable block sample, obtaining clear images of the two spring mounting positions on its top, and pre-stores these images as a standard template in the controller 76. The standard template has marked the areas where the two springs are located as key detection points. During operation, when the first positioning sensor 75 senses that the mounting base 4 carrying the inflatable block has moved directly below the detection position 15, it triggers the detection probe 74 to acquire images of the current inflatable block. The controller 76 compares and analyzes the captured real-time images with the pre-stored standard template, focusing on comparing the image features of the two key detection points. If both detection points identify spring features, the product is determined to be a qualified product; if neither detection point identifies spring features, the product is determined to be a defective product.

[0062] The corresponding operating principle is as follows: When the air block, which has been assembled for the first time and fixed twice, rotates with the processing table 3 into the inspection station 15 and stops precisely below the inspection box 73, the first positioning sensor 75 is triggered, sending a positioning signal to the controller 76. The controller 76 then instructs the inspection probe 74 to start, taking an image of the top of the air block below, and obtaining a real-time image including the preset installation positions of the two springs.

[0063] Subsequently, the controller 76 retrieves a pre-stored standard template image and performs a high-precision comparison between it and the real-time image, particularly focusing on two preset key detection point areas. Image processing algorithms are then used to analyze whether the features of this area match the characteristics of the spring in the standard template.

[0064] The controller 76 makes a judgment based on the comparison results: if both key detection points successfully match the spring features, a "qualified" judgment signal is generated; if any one or two detection points fail to match, a "unqualified" judgment signal is generated. This judgment signal will be output to the central control system of the device, and the control system will use this signal to sort the products at the subsequent receiving station 16, guiding qualified and unqualified products to different collection paths, thereby completing the automatic inspection and sorting of assembly quality.

[0065] Referring to Figure 8, the receiving mechanism 8 includes a fourth support platform 81, a second sliding platform 82, a fifth linear actuator 83, a sliding seat 84, a mounting bracket 85, a sixth linear actuator 86, and a first gripper 87. The fourth support platform 81 is fixedly connected to the surface of the base 1. The second sliding platform 82 is fixedly connected to the upper part of one outer wall of the fourth support platform 81. The fifth linear actuator 83 (preferably a high-precision electric actuator) is fixedly connected to the side of the second sliding platform 82 away from the fourth support platform 81. The sliding seat 84 is slidably connected to the side of the second sliding platform 82 away from the fourth support platform 81, and the output shaft of the fifth linear actuator 83 is fixedly connected to the sliding seat 84. The sixth linear actuator 86 (preferably an electric actuator) is fixedly connected to the side of the sliding seat 84 away from the second sliding platform 82. The output shaft of the sixth linear actuator 86 faces the base 1, and the mounting bracket 85 is fixedly connected to the output shaft of the sixth linear actuator 86. Finally, the first gripper 87 is fixedly connected to the side of the mounting bracket 85 away from the sixth linear actuator 86.

[0066] Finally, refer to Figure 9 The drive device 2 includes an equipment box 21 fixedly connected to the base 1. The processing table 3 is rotatably connected to the top of the equipment box 21 via bearings. A connecting shaft 22 is rotatably connected to the middle of the bottom wall of the equipment box 21. The top of the connecting shaft 22 passes through the equipment box 21 and is fixedly connected to the processing table 3. A grooved wheel 23 is fixedly connected to the middle of the outer wall of the connecting shaft 22. Each grooved wheel 23 has eight actuating grooves 24. At the same time, a drive source 25 (preferably a geared motor with self-locking function) is fixedly connected to the bottom wall of the equipment box 21. A dial 26 is fixedly connected to the output shaft of the drive source 25. Eight actuating shafts 27 are fixedly connected around the outer edge of the dial 26 away from the drive source 25. Two of the actuating shafts 27 are set in the corresponding actuating grooves 24. It should be noted that no matter what angle the drive source 25 drives the dial 26 to rotate, there will always be two actuating shafts 27 located in the corresponding actuating grooves 24, ensuring the stability of the operation of the drive device 2.

[0067] The operating principle of the drive device 2 is as follows: after the drive source 25 is started, it drives the dial 26 on its output shaft to rotate continuously. The actuating shaft 27 on the outer edge of the dial 26 rotates accordingly. When a certain actuating shaft 27 enters the corresponding radial actuating groove 24 on the grooved wheel 23, it actuates the grooved wheel 23 and the connecting shaft 22 that is coaxially fixed to it to rotate a certain angle.

[0068] Since the top of the connecting shaft 22 is fixedly connected to the processing table 3, it drives the processing table 3 and its eight evenly distributed mounting seats 4 to rotate together. When the actuating shaft 27 rotates through a certain angle, it slides out of the actuating groove 24, and the grooved wheel 23 will briefly stop rotating due to inertia and positioning requirements. At this time, the processing table 3 stops, so that one of the mounting seats 4 on it is precisely aligned with a certain functional station.

[0069] In such a cycle, the driving source 25 drives the turntable 26 to rotate continuously. Through the periodic engagement and separation between the拨动 shaft 27 and the拨动 groove 24, the continuous rotational motion is converted into the precise intermittent rotational motion of the processing table 3, enabling the mounting base 4 to carry the workpiece and step through each station in sequence, thus completing the automated assembly line operation.

[0070] The implementation principle of the first embodiment of this application is as follows: The device drives the processing table 3 to perform precise intermittent indexing rotation through the driving device 2 on the base 1, enabling the circumferentially distributed mounting bases 4 to step through each functional station in sequence.

[0071] First, the air chuck automatically feeds along the inclined slideway 1711 under the action of gravity, and is picked up and precisely placed in the空载 mounting base 4 by the feeding mechanism 5. Subsequently, the mounting base 4 carrying the workpiece first enters the first spring assembly station 12, where the grasping actuator 123 and the first fixed cylinder 125 at this station cooperate to complete the grasping, placement, and pressing of the first spring; Then it enters the second spring assembly station 13, and the second spring is assembled with the same operation. After that, the workpiece enters the secondary fixing station 14, where the two second fixed cylinders 65 reciprocally press the assembled springs to ensure firm installation. Then, the workpiece rotates to the inspection station 15, and industrial cameras take pictures and perform visual comparison with the standard template to automatically determine whether the assembly is qualified. Finally, the discharging mechanism 8 retrieves the processed workpiece. Embodiment

[0072] Based on the first embodiment, this embodiment adds a recycling section 9, which is arranged between the inspection mechanism 7 and the discharging mechanism 8 and is used for automatically sorting and guiding the air chucks that have completed inspection.

[0073] Specifically, referring to Figure 10 and Figure 11 , the recycling section 9 includes two slide rails 91, a qualified product collection box 92, and a non - qualified product collection box 93. Among them, both the qualified product collection box 92 and the non - qualified product collection box 93 are arranged on one side of the base 1 close to the inspection mechanism 7. At the same time, both slide rails 91 are fixedly connected to the top surface of the base 1, and the slide rails 91 gradually decrease from the side close to the center of the base 1 towards the side away from the center of the base 1. It should be noted that the two slide rails 91 point to different angles, and the ends of the two slide rails 91 are respectively located above the corresponding qualified product collection box 92 and non - qualified product collection box 93, so that the corresponding qualified products / non - qualified products on the slide rails 91 will fall into the corresponding qualified product collection box 92 or non - qualified product collection box.

[0074] To achieve automatic linkage of the sorting operation, a toothed plate 94 is fixedly connected to the lower part of the side of the sliding seat 84 near the second sliding table 82. A drive gear 95 meshes on the toothed plate 94, and a first drive shaft 96 is fixedly connected to the drive gear 95. The two ends of the first drive shaft 96 are rotatably connected to the second sliding table 82 and the base 1, respectively. A main drive gear 97 is fixedly connected to the lower part of the outer wall of the first drive shaft 96, and a secondary drive gear 98 meshes on the main drive gear 97. A second drive shaft 99 is fixedly connected to the secondary drive gear 98, the bottom end of the second drive shaft 99 is rotatably connected to the base 1, and a guide rail 100 is fixedly connected to the top end of the second drive shaft 99.

[0075] Reference Figure 11 and Figure 12 To achieve precise control of the receiving position, a second positioning sensor 101 is fixedly connected to the upper part of the sliding seat 84 near the second sliding table 82. Three positioning elements 102 that cooperate with the second positioning sensor 101 are fixedly connected in the extending direction of the second sliding table 82.

[0076] A protective cover is fixedly connected to the top surface of the base 1. The protective cover houses the main drive gear 97 and the auxiliary drive gear 98. The first drive shaft 96 and the second drive shaft 99 are both rotatably connected to the protective cover. This reduces the impact of impurities on the meshing between the main drive gear 97 and the auxiliary drive gear 98.

[0077] Therefore, the specific implementation principle of this embodiment two is as follows: After the detection mechanism 7 completes the qualification judgment of the air-inflated block, the control system drives the receiving mechanism 8 to work according to the judgment result. If it is a qualified product, the fifth linear actuator 83 drives the sliding seat 84 to move until the second positioning sensor 101 senses the positioning component 102 of the corresponding qualified product station. At this time, the sliding seat 84 stops, and the first gripper 87 releases the air-inflated block. During this movement, the toothed plate 94 drives the drive gear 95 and the first drive shaft 96 to rotate. Through the transmission of the main drive gear 97 and the auxiliary drive gear 98, the second drive shaft 99 and its guide rail 100 are finally driven to swing to the angle of the corresponding qualified product slide rail 91, guiding the product to slide into the qualified product collection box 92. If it is a non-qualified product, the sliding seat 84 moves to the non-qualified product station defined by another set of positioning components 102. The linkage mechanism drives the guide rail 100 to swing synchronously to the angle of the corresponding non-qualified product slide rail 91, realizing automatic diversion. The entire process realizes sorting guidance through mechanical linkage, without the need for additional independent drive.

[0078] Finally, refer to Figure 13This is a diagram showing the state of the spring after it has been installed in the mounting groove of the air expansion block. It should be noted that the spring is a conical spring, and the inner wall of the mounting groove is also conical with a large bottom area and a small opening area. The size of the first fixing cylinder 125 and the second fixing cylinder 65 is the size of the opening of the mounting groove. This means that as the first fixing cylinder 125 or the second fixing cylinder 65 descends, it can compress the spring into the mounting groove of the air expansion block.

[0079] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
