Description

Technical Field

[0001] The utility model relates to the technical field of screwdriving machines, and more specifically, it is a turntable-type screwdriving machine. Background Art

[0002] The turntable-type screwdriving machine is an efficient automatic assembly device used to quickly and accurately complete the screwing work. With the continuous improvement of the automation level in the manufacturing industry, in order to improve production efficiency and reduce labor costs, the turntable-type screwdriving machine has become an indispensable part of modern automated production lines.

[0003] In the current prior art, the turntable-type screwdriving machine generally adopts a multi-axis platform with multiple intelligent electric screwdrivers to process products in multiple fixed fixtures arranged at intervals on the turntable respectively. This type of turntable-type screwdriving machine has a high cost, and the fixed fixtures are relatively simple. When some workpieces are installed on these fixtures with the processing surface facing up, their non-processing surfaces are not flat. If used as a positioning reference, it may lead to inaccurate positioning, and then cause the workpiece to shift or deform during screwing, affecting the quality of screwing. Moreover, when the screwing position is at the edge of the product, the fixture may block the moving path of the intelligent electric screwdriver during processing. In addition, when the processing surface of the product is relatively complex, it will reduce the accuracy of identifying and positioning the position to be processed, and then reduce the quality of screwing. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a turntable-type screwdriving machine, aiming to solve the technical problems existing in the prior art, such as the low positioning accuracy and connection stability of fixed fixtures for workpieces, blocking the screwing path, and the difficulty in identifying and positioning the screwing position, resulting in low accuracy of screwing and affecting the quality of screwing.

[0005] To solve the above technical problems, the utility model provides a turntable-type screwdriving machine, including:

[0006] A machine table, on which there are an adjacent indexing turntable and an intelligent screwing mechanism, and the indexing turntable is rotationally connected to the machine table; two turning and loading mechanisms, which are centrosymmetric along the rotation axis center of the indexing turntable. The turning and loading mechanism includes a rotation driving member and a mounting support. A turning frame is rotatably provided on the mounting support. One side of the turning frame is provided with a movable pressing member, and the other side is provided with a positioning plate. The workpiece is placed between the positioning plate and the pressing member. A plurality of positioning holes are arranged at intervals on the positioning plate. Among them, the rotation driving member is used to turn the turning frame so that the positioning plate is opposite to the output end of the intelligent screwing mechanism, and the intelligent screwing mechanism is used to screw the workpiece.

[0007] When processing the workpiece mounted on one of the turnover fixture mechanisms, another workpiece can be taken out or fastened on the other turnover fixture mechanism at the same time. After the processing is completed, the indexing turntable rotates and exchanges the positions of the two turnover fixture mechanisms. The design of the indexing turntable is conducive to ensuring the continuous processing of the workpiece, optimizing and improving the processing efficiency;

[0008] The movable pressing member can more conveniently place the workpiece into the turnover fixture mechanism or take it out from the turnover fixture mechanism, effectively simplifying the steps of installing the workpiece into the turnover fixture mechanism, which is conducive to improving the loading and unloading efficiency of the workpiece, and thus improving the efficiency of automatic screw locking; the workpiece is fastened in the turnover fixture mechanism by the pressing member and the positioning plate together, and the position of the workpiece is further restricted by the turning frame. On the one hand, it can reduce the positioning error caused by the non-machined surface as the positioning reference of the workpiece. On the other hand, when the workpiece is turned and the screws are locked, the workpiece can be prevented from shifting and deforming, and the area of the workpiece that does not need to be processed can also be protected; the positioning plate can block most of the area of the machined surface of the workpiece, leaving only the positioning holes for positioning and assisting in screw locking, which can simplify the image of the machined surface and reduce the interference of complex elements when the intelligent locking mechanism identifies and locates the screw locking position, which is conducive to improving the accuracy and accuracy of screw locking.

[0009] Preferably, the turning frame is provided with through holes, and a plurality of elastic support columns are spaced on the positioning plate, and the plurality of elastic support columns extend towards the through holes.

[0010] The plurality of elastic support columns serve as positioning references, reducing the contact area between the positioning plate and the workpiece, preventing uneven areas from interfering with the positioning, and avoiding position deviation when the workpiece is installed in the turnover fixture mechanism. The elastic support columns support the workpiece, and their elastic force has a certain ability to relieve the positioning error caused by the uneven area of the workpiece. In addition, when the pressing member presses the workpiece, the elastic support columns can also buffer the pressing force received by the workpiece to a certain extent, preventing the workpiece from being deformed and damaged on the surface to a large extent.

[0011] Preferably, a plurality of elastic limit columns are provided on the turning frame, the plurality of elastic limit columns are spaced along the outer periphery of the through hole, and the plurality of elastic limit columns are opposite to the pressing member, and a limit convex column extending towards the through hole is provided on the positioning plate.

[0012] Multiple elastic limit posts and limit convex posts can further limit the position of the workpiece within the turnover fixture mechanism, enabling the area to be processed and the positioning area of the workpiece to align with multiple positioning holes and limit convex posts on the positioning plate. At the same time, it can prevent the positioning inaccuracy caused by the offset of the workpiece in the direction of the plane of the turnover frame during operation, further improving the positioning accuracy and connection stability of the turnover fixture mechanism for the workpiece, so as to improve the accuracy of the intelligent locking mechanism for automatically locking screws; the elastic limit posts are opposite to the pressing member, which can prevent the collision between the pressing member and the turnover frame, reduce the damage caused by the collision, and extend its service life.

[0013] Preferably, a plurality of adjusting pressure rods are provided at intervals on the pressing member. The adjusting pressure rod includes a screw rod and a pressing head fixedly connected to one end of the screw rod. The pressing head is used to adjust the depth of the screw rod screwed into the pressing plate.

[0014] The adjusting pressure rod can adjust the screwing depth between it and the pressing member according to different situations to adjust the pressing force on the workpiece, preventing deformation or other damage to the workpiece caused by too large or too small pressing force; when the pressing member is covered on the turnover frame, the adjusting pressure rod can abut against the uneven area of the non-processing surface of the workpiece, further restricting the movement of the workpiece in the direction relative to the pressing member and the positioning plate, and preventing the positioning of the workpiece from shifting due to the uneven area.

[0015] Preferably, connection blocks and clamping grooves are provided at intervals on the outer edge of the turnover frame. One side of the pressing member is rotatably connected to the connection block, and the other side is provided with an elastic buckle adapted to the clamping groove.

[0016] The pressing member is rotatably connected to the connection block, which can leave a certain interval between the pressing member and the turnover frame. This interval allows more types of workpieces to be placed between the pressing member and the positioning plate, so as to improve the applicability of this turnover fixture mechanism; the clamping between the clamping groove and the buckle can more conveniently open and close the pressing member, so as to improve the loading and unloading efficiency of the workpiece, and thus improve the efficiency of automatically locking screws.

[0017] Preferably, a rotating connecting member is provided at the connection between the turnover frame and the mounting seat. One end of the rotating connecting member is detachably connected to the turnover frame, and the other end is rotatably connected to the mounting seat and extends outward from the mounting seat with a rotating shaft.

[0018] The turnover frame, the pressing member, and the positioning plate are connected together. Therefore, the turnover frame is rotatably connected to the mounting seat through the rotating connecting member, that is, the turnover frame and the pressing member and the positioning plate connected to the turnover frame are replaceable. On the one hand, this is conducive to expanding the structural design of the turnover fixture mechanism to adapt to different types of workpieces, and on the other hand, this modular design is also conducive to subsequent maintenance.

[0019] Preferably, a baffle is fixedly connected to one of the rotating shafts, two opposite groove-shaped photoelectric sensors are arranged at intervals on the outer side of the mounting support, the baffle can trigger the two groove-shaped photoelectric sensors, and the other rotating shaft is detachably connected to the output end of the rotation driving member.

[0020] The two groove-shaped photoelectric sensors are triggered every time the turnover tooling mechanism turns 180°, which can improve the accuracy of the angle turnover of the turnover tooling mechanism, is beneficial to improving the positioning accuracy of the intelligent screwing mechanism for the processing position, and further improves the quality of screw screwing; the detachable connection between the rotating shaft and the output end of the turnover driving member is more convenient when replacing the rotating connecting piece or disassembling the turnover driving member, which is beneficial to subsequent maintenance.

[0021] Preferably, the intelligent screwing mechanism includes a three-axis moving assembly, a screw feeder, and a screw locking assembly. The output end of the three-axis moving assembly is connected to the screw locking assembly, and the output end of the screw feeder is connected to the screw locking assembly.

[0022] The three-axis moving assembly can maximize the moving range of the screw locking assembly and also improve the accuracy of the movement of the screw locking assembly, enabling the screw locking assembly to smoothly and accurately screw screws at multiple positions; the screw feeder can directly supply screws continuously to the intelligent screwing mechanism without the screw locking assembly moving to its output end, which can greatly shorten the moving path of automatically screwing screws for a single workpiece and effectively improve the efficiency of automatic screw screwing.

[0023] Preferably, the screw locking assembly includes a CCD camera module, a lifting module, an intelligent electric screwdriver, and a screw suction module. The CCD camera module is used to identify and locate the screw locking position. The screw suction module is connected to the output end of the screw feeder, and the lifting module is used to drive the intelligent electric screwdriver to approach or move away from the screw suction module.

[0024] The CCD camera can identify the positioning holes on the positioning plate, enabling the intelligent electric screwdriver to accurately screw screws; the intelligent electric screwdriver can also detect and record the torque parameters and screwing angles of each screw during normal screw screwing; the lifting module can provide additional lifting ability for the intelligent electric screwdriver, enabling the intelligent electric screwdriver to approach or move away from the screw suction module, so that during the process of transferring and screwing screws, there is no interference between the intelligent electric screwdriver and the screw suction module, thereby improving the stability of screw screwing.

[0025] Preferably, a torque inspection table and a waste screw box are also provided on the machine table.

[0026] The torque inspection table can accurately detect and record the torque value when the screw is tightened, ensure that the tightening torque of the screw is within the preset range, and promptly detect abnormal conditions during the tightening process, effectively preventing unqualified products caused by poor screw tightening, thereby reducing the rework rate and improving the quality and stability of the product.

[0027] The waste screw box can collect the waste generated during the screw-locking process, keep the working environment clean and orderly, improve production efficiency, and at the same time avoid affecting the normal operation of the production line and reducing potential safety hazards. In addition, the collected waste screws can be recycled after appropriate treatment, reducing resource waste.

[0028] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0029] The turnover fixture mechanism provided with a movable pressing plate, a turnover frame, and a positioning plate is adopted. While improving the screw-locking efficiency, it can fasten the workpiece in the turnover fixture mechanism, effectively avoiding the offset of the workpiece inside the turnover fixture mechanism, preventing the workpiece from shifting or deforming during automatic screw locking, and having a certain protective effect; the pretreatment method of simultaneously clamping the processed surface and the non-processed surface of the workpiece can greatly reduce the influence of using a single non-processed surface as the positioning reference on the positioning accuracy of the workpiece, effectively improving the positioning accuracy of the workpiece, and further improving the accuracy and quality of automatic screw locking; the positioning plate can cover most of the complex structures on the processed surface, only leaving multiple positioning holes to position the screw-locking position, which can greatly simplify the image of the processed surface and greatly improve the recognition and positioning ability of the intelligent locking mechanism for the processing position, further improving the accuracy and quality of automatic screw locking.

[0039] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0040] In this embodiment, please refer to Figures 1 to 4 As shown, the present utility model provides a turntable type screwdriver, which includes a machine table 10. An adjacent divider turntable 20 and an intelligent locking mechanism are provided on the machine table 10. The divider turntable 20 is circular and rotatably connected to the machine table 10. Two centrally symmetric turning and carrying mechanisms 30 are provided along the axis of the divider turntable 20. The turning and carrying mechanism 30 includes a rotation driving member 35 and a mounting support 31. A "hui"-shaped turning frame 32 is rotatably provided on the mounting support 31. A movable pressing member 33 is provided on one side of the turning frame 32, and a positioning plate 34 is provided on the other side. A workpiece 40 abuts between the pressing member 33 and the positioning plate 34 and passes through the turning frame 32. A plurality of positioning holes 341 are provided at intervals on the positioning plate 34. Among them, the rotation driving member 35 is used to rotate the turning frame 32 so that the positioning plate 34 faces the output end of the screw locking assembly 60, and the intelligent locking mechanism is used to lock screws into a plurality of threaded holes 41.

[0041] It can be understood that the two sides where the two turning and carrying mechanisms 30 are located are respectively a processing station and a station to be processed; the turning frame 32, the pressing member 33, and the positioning plate 34 are all planar structures. The central part of the turning frame 32 is in a hollow state, and the shape of the hollow part should be such that the workpiece 40 can pass through, so it can be of other shape structures; a plurality of threaded holes 41 and positioning posts 42 opposite to the plurality of positioning holes 341 are provided on the workpiece 40. The positioning holes 341 and the positioning posts 42 are used to assist the intelligent locking mechanism 60 in positioning the position to be processed. Therefore, the pattern formed by the projection of the positioning post 42 onto the positioning hole 341 should be recognizable, generally a cross pattern. The intelligent locking mechanism 60 identifies and positions the position of the threaded hole 41 through the positioning holes 341 on the positioning plate 34 and the positioning posts 42 exposed in the positioning holes 341.

[0042] In one embodiment, please refer to Figures 1 to 3 As shown, the turning frame 32 is provided with through holes, and a plurality of elastic support columns 342 are provided at intervals on the positioning plate 34. The plurality of elastic support columns 342 extend towards the through holes.

[0043] It can be understood that a plurality of processing bosses 43 extending toward the through hole are provided at intervals on the workpiece 40. The elastic support columns 342 are in contact with and support the processing bosses 43, and together with the pressure of the pressing member 33 on the workpiece 40, the workpiece 40 can be clamped inside the turning fixture mechanism 30; the plurality of processing bosses 43 are machined surfaces, and their end faces are parallel and flat to each other. When used as a positioning reference, they can ensure that the workpiece 40 does not shift or vibrate during installation and turning together with the elastic support columns; both the processing bosses 43 and the elastic support columns 342 are cylindrical, and a limiting shaft can be added between the processing bosses 43 and the elastic support columns 342 when necessary.

[0044] Specifically, a plurality of elastic limiting columns 321 are provided on the turning frame 32. The plurality of elastic limiting columns 321 are arranged at intervals along the outer periphery of the through hole, and the plurality of elastic limiting columns 321 are opposite to the pressing member 33. A limiting boss 343 extending toward the through hole is provided on the positioning plate 34.

[0045] It can be understood that the plurality of elastic limiting columns 321 surround and abut against the workpiece 40. A limiting hole 44 is also provided on the workpiece 40, and the limiting hole 44 is matched with the limiting boss 343. The plurality of elastic limiting columns 321 and the limiting boss 343 jointly position the workpiece 40; to save costs, the elastic limiting columns 321 can use the same components as the elastic support columns 342; a certain interval can be reserved between the elastic limiting columns 321 and the edge of the through hole to adapt to larger workpieces 40.

[0046] In addition, the limiting boss 343 can also be set as an adjustable frustum structure to adapt to more types of workpieces 40.

[0047] More specifically, a plurality of adjusting pressure rods 331 are provided at intervals on the pressing member 33. The adjusting pressure rod 331 includes a screw rod 3311 and a pressing head 3312 fixedly connected to one end of the screw rod 3311. The pressing head 3312 is used to adjust the depth of the screw rod 3311 screwed into the pressing plate.

[0048] It can be understood that the pressing member 33 is a frame structure. The plurality of adjusting pressure rods 331 are arranged at intervals on the frame and are all opposite to the workpiece 40. Since the pressed surface of the workpiece 40 is a non-machined surface, it may be uneven. The pressing head 3312 abuts against and presses each part of the workpiece 40, so that the pressure on each part of the workpiece 40 should be relatively uniform and completely abut against the positioning plate, preventing the workpiece 40 from shifting; the pressing head 3312 is made of flexible or elastic material to prevent damage to the workpiece 40.

[0049] In addition, a knob can be further provided at the other end of the screw 3311 to facilitate the adjustment of the screwing depth of the adjusting lever 331; a relative and adjustable abutting structure can be provided on the pressing member 33 or the flipping frame 32 to ensure that the pressing member 33 does not directly collide with the flipping frame 32, so as to extend the service life of each component.

[0050] In one embodiment, please refer to Figure 2 As shown, connecting blocks 322 and clamping grooves 323 are spacedly arranged on the outer edge of the flipping frame 32. One side of the pressing member 33 is rotatably connected to the connecting block 322, and an elastic buckle 332 adapted to the clamping groove 323 is provided on the other side.

[0051] It can be understood that the connecting block 322 has a cuboid structure, is arranged on the side surface of the flipping frame 32 and is perpendicular to the flipping frame 32, and does not affect the loading and unloading of the workpiece 40. The top of the connecting block 322 is rotatably connected to the pressing member 33; the elastic buckle 332 is hook-shaped, the middle part of which is rotatably connected to the pressing member 33, and one end of the elastic buckle 332 can be pushed by an elastic member so that the hook at the other end is buckled into the clamping groove 323 to realize the clamping connection between the pressing member 33 and the flipping frame 32.

[0052] In addition, the connecting block 322 can also be arranged on the side surface of the flipping frame 32; a protruding connecting structure can be provided on the pressing member 33 to adjust the position of the pressing member 33 when it is covered on the flipping frame 32; the elastic buckle 332 and the clamping groove 323 can also be designed on the corresponding side surfaces or their positions can be swapped.

[0053] In one embodiment, please refer to Figure 2 and Figure 4 As shown, a rotating connecting member 36 is provided at the connection between the flipping frame 32 and the mounting seat 31. One end of the rotating connecting member 36 is detachably connected to the flipping frame 32, the other end is rotatably connected to the mounting seat 31, and a rotating shaft 361 extends outward from the mounting seat 31.

[0054] It can be understood that the structure of the rotating connecting member 36 is a stepped shaft, and a connecting groove is provided on the shaft section connected to the flipping frame 32, and the connecting groove abuts against the flipping frame 32.

[0055] In addition, the rotating connecting member 36 can also be provided with clamping grooves that abut against both sides of the flipping frame 32, so that the flipping frame 32 is slidably snapped into the clamping grooves and then connected by bolts.

[0056] Specifically, a retaining piece 362 is fixedly connected to one of the rotating shafts 361, and two opposite groove-shaped photoelectric sensors 37 are spacedly arranged on the outer side of the mounting seat 31. The retaining piece 362 triggers the groove-shaped photoelectric sensor 37 through the groove of the groove-shaped photoelectric sensor 37, and the other rotating shaft 361 is detachably connected to the output end of the rotation driving member 35.

[0057] It can be understood that one of the groove-shaped photoelectric sensors 37 should be triggered by the baffle 362 when the flipping frame 32 rotates 180°, so as to realize flipping the positioning plate 34 to face the screw locking assembly 60 or restoring it; the rotation driving member 35 includes a motor, a reducer, and an output shaft connected in sequence. A keyway is provided on the output shaft, and a groove for the output shaft and the key to slide and insert is provided on another rotating shaft 361, so as to achieve convenient detachable connection while the output shaft drives the rotating connecting member 36 to rotate.

[0058] In addition, keys and keyways can be provided on another rotating shaft 361, and corresponding grooves can be provided on the output shaft; bolt fitting connection can also be used to replace key connection.

[0059] In one embodiment, please refer to Figure 1 As shown, the intelligent lock attachment mechanism includes a three-axis moving assembly 50, a screw feeder 70, and a screw locking assembly 60. The output end of the three-axis moving assembly 50 is connected to the screw locking assembly 60, and the output end of the screw feeder 70 is connected to the screw locking assembly 60.

[0060] It can be understood that the indexing turntable 20, the three-axis moving assembly 50, the screw locking assembly 60, and the two flipping and carrying mechanisms 30 are all electrically connected; the three-axis moving assembly 50 can drive the screw locking assembly 60 to approach or move away from the positioning plate 34; the screw locking assembly 60 can automatically identify and position the position of the screw and lock the screw, and at the same time can detect and record the torque parameters, locking angles, etc. of each screw; the screw feeder 70 can provide screws for the screw locking assembly 60 through a pipeline, and there is no need for the screw locking assembly 60 to move to the output end of the screw feeder. In addition, the screw feeder 70 should be adjacent to the three-axis moving assembly 50 to shorten the distance between it and the screw locking assembly 60, thereby reducing the difficulty of conveying screws.

[0061] Please refer to Figure 1 As shown, the three-axis moving assembly 50 includes a first linear guide 511 and a first linear driving member 51. The first linear guide 511 and the first linear driving member 51 are parallel and spaced apart. A second linear driving member 52 is connected between the first linear guide 511 and the first linear driving member 51. A third linear driving member 53 is connected to the second linear driving member 52. A moving seat 531 is provided on the third linear driving member 53. The screw locking assembly 60 is connected to the moving seat 531. The driving directions of the first linear driving member 51, the second linear driving member 52, and the third linear driving member 53 are perpendicular to each other; a plurality of mounting posts 54 are spaced between the first linear guide 511 and the first linear driving member 51 and the machine table 10. The indexing turntable 20 is located between the first linear guide 511 and the first linear driving member 51.

[0062] It can be understood that a relatively large space is reserved between the first linear guide rail 511 and the first linear drive 51. The divider turntable 20 can be arranged close to this space to shorten the stroke of the screw locking assembly 60. The third linear drive 53 and the screw locking assembly 60 should be located on one side close to the divider turntable 20 to achieve normal automatic screw locking and shorten the stroke of the screw locking assembly 60. The mounting post 54 can raise the overall height of the three-axis moving assembly 50 to expand the moving range of the third linear drive 53 and the screw locking assembly 60 in the Z-axis direction.

[0063] Specifically, please refer to Figure 1 and Figure 5 As shown, the screw locking assembly 60 includes a CCD camera module 61, a lifting module 62, an intelligent electric screwdriver 63, and a screw sucking module 64. The CCD camera module 61 is used to identify and locate the screw locking position. The screw sucking module 64 is connected to the output end of the screw feeder 70. The lifting module 62 is used to drive the intelligent electric screwdriver 63 to approach or move away from the screw sucking module 64.

[0064] The lifting module 62 includes a lifting guide rail 621 arranged in the Z-axis direction and a lifting seat 622 slidably clamped on the lifting guide rail 621. The screw sucking module 64 includes a plurality of screw sucking nozzles 641. One end of the screw sucking nozzle 641 is elastically rotatably connected to the moving seat 531 and is provided with a feeding pipe 642. A channel 6411 for the screw to slide is provided between the plurality of screw sucking nozzles 641. The plurality of feeding pipes 642 are connected to the channel 6411 and the output end of the screw feeder 70. The output end of the intelligent electric screwdriver 63 is provided with a tail missing bit 631. The tail missing bit 631 is coaxial with the channel 6411. The lifting module 62 is used to drive the intelligent electric screwdriver 63 to approach or move away from the screw sucking module 64.

[0065] It can be understood that the CCD camera module 61 should be arranged downward to identify the image of the positioning plate 34. The displacement sensor 64 is used to detect the distance that the lifting seat 622 drives the intelligent electric screwdriver 63 to move in real time to ensure the normal progress of screw locking. The screw is conveyed from the output end of the screw feeder 70 to the feeding pipe 642, then enters the channel 6411 through the feeding pipe 642 and slides. Then it is clamped by the lower ends of the plurality of screw sucking nozzles 641. The upper ends of the plurality of screw sucking nozzles 641 are elastically rotatably connected to the moving seat 531, which can make the lower ends of the plurality of screw sucking nozzles 641 approach each other and clamp the screw. When the tail missing bit 631 passes through the channel 6411 and abuts against the screw and starts to lock the screw, the end of the plurality of screw sucking nozzles 641 that clamp the screw will be squeezed outward and opened. After completing a single screw locking, the plurality of screw sucking nozzles 641 will return to their original state due to the elastic force. The tail missing bit 631 is a vertical straight rod, and the channel 6411 is a vertical straight column. When the intelligent electric screwdriver 63 moves up and down, the tail missing bit 631 also moves up and down vertically. Therefore, the tail missing bit 631 can pass through the channel 6411 and complete the screw locking.

[0066] In addition, the CCD camera module 61 can be detachably connected to the moving base 531 and its position on the moving base 531 can be adjusted.

[0067] In this embodiment, please refer to Figure 1 As shown, a torque inspection table 11 and a waste screw box 12 are also provided on the machine table.

[0068] It can be understood that the torque inspection table 11 is used to detect and record the torque value when the screw is tightened, ensure that the tightening torque of the screw is within the preset range, and timely detect abnormal conditions during the tightening process; the waste screw box 12 is used to recycle the waste generated during the screw locking process, keep the working environment clean and orderly, improve production efficiency, and at the same time avoid affecting the normal operation of the production line and reduce potential safety hazards. The torque inspection table 11 and the waste screw box 12 should be set within the moving range of the screw locking assembly 60 driven by the three-axis moving assembly 50. Therefore, the torque inspection table 11 and the waste screw box 12 are located between the intelligent screw attachment mechanism and the divider turntable 20 to reduce the moving stroke of the screw locking assembly 60 and improve the screw locking efficiency.

[0069] The specific application process of the present utility model is as follows:

[0070] The turning and loading tool mechanism 30 with the processed part 40 that has completed screw locking is transferred to the area to be processed. The elastic buckle 332 is separated from the card slot 323 on the turning frame 32, the pressing member 33 is turned over and opened, the processed part 40 with the screw locked is taken out, and the new processed part 40 is clamped between a plurality of elastic limiting posts 321 with the threaded hole 41 and the positioning post 42 facing downwards and placed on the positioning plate 34, so that the limiting convex post 343 slides and is clamped into the limiting hole 44, and the processing convex post 43 abuts against the elastic support post 342 to complete the positioning of the processed part 40. The pressing member 33 is covered, the elastic buckle 332 is buckled into the card slot 323, and each adjusting lever 331 is adjusted to complete the clamping of the processed part 40, and the automatic screw locking starts.

[0071] The divider turntable 20 rotates 180°, causing the turnover carrier mechanism 30 with the newly processed workpiece 40 to be transferred to the processing area. The rotation drive member 35 drives the turnover frame 32 to rotate 180° through the rotating connecting member 36. One of the groove-shaped photoelectric sensors 37 is triggered by the baffle 362 connected to the rotating shaft 361, causing the turnover frame 32 to stop rotating. At this time, the positioning plate 34 faces upward and is opposite to the screw locking assembly 60. The CCD camera module 61 identifies each positioning hole 341 and positioning post 42 on the positioning plate 34 to determine the screw locking position. The screw feeder 70 conveys the screws to the lower end of the screw suction nozzle 641 through the feeding pipeline 642 and the channel 6411. The three-axis moving assembly 50 drives the screw locking assembly 60 to first move to the torque inspection table. After detecting and recording the torque data, it moves to the screw locking position, aligning the newly conveyed screw in the screw suction nozzle 641 with the threaded hole 41. The lifting module 62 drives the intelligent electric screwdriver 63 to descend and approach the screw suction module 64. The tail missing bit 631 passes through the channel 6411 and abuts against the screw, and continues to descend to complete a single screw locking. The three-axis moving assembly 50 then drives the screw locking assembly 60 to move to other screw locking positions. After all the screw locking positions of the workpiece 40 are completed, the three-axis moving assembly 50 drives the screw locking assembly 60 away from the turnover carrier mechanism 30. The turnover frame 32 then flips 180° to restore its original state and is sent back to the area to be processed by the divider turntable 20.

[0072] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
