Description

Technical Field

[0001] This utility model belongs to the field of automatic screw fastening technology, and in particular relates to an automatic screw fastening line with a sensor. Background Technology

[0002] When manufacturing products such as sensors, the upper housing of the sensor needs to be fixed to the lower housing by tightening screws. In the traditional production process, screws are usually tightened manually, but manual operation has disadvantages such as high labor intensity and low screw-tightening efficiency. With the application of automated screw-tightening technology, more and more screw-tightening work is being done by automatic screw-tightening machines. For example, Chinese invention patent with authorization announcement number CN119217037B discloses a screw fastening mechanism and an automatic screw-tightening machine, and Chinese invention patent application with application number 202510263287.5 discloses a four-axis automatic screw-tightening machine.

[0003] While the aforementioned patented technical solution enables automatic screw fastening of products, it still requires manual or machine placement of the product to be screwed into the positioning fixture below the fastening assembly. The automatic screw fastening machine then performs the fastening operation. After the screws are fastened, the product is removed from the positioning fixture manually or by machine, and then placed back into the fixture. Since the fastening process takes time, and the repeated loading and unloading operations also consume time, the aforementioned technical solution suffers from low fastening efficiency and the inability to perform continuous, assembly-line automatic screw fastening.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0043] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0044] See appendix Figure 1 As shown, an automatic screw-locking line for sensors includes a frame-type structure frame 1, a support plate 11 horizontally fixed to the upper end face of the frame 1 by bolts, a rotating mechanism 2, a positioning mechanism including a push cylinder 3 and a positioning fixture 4, a feeding mechanism 5, a screw-locking mechanism 6, a discharging mechanism 7, a feeding conveying mechanism 8, and a detection mechanism 9.

[0045] See appendix Figure 4 As shown, the rotating mechanism 2 includes a support frame 21 disposed below the support plate 11, and a divider 22 fixedly mounted on the upper surface of the support frame 21 by bolts. The divider 22 is prior art, and a four-position divider of model RU110DT can be selected. A support plate through hole (not shown in the figure) is provided on the support plate 11. The fixed end and rotating end of the divider are both inserted into the support plate through hole and extend above the support plate 11. The fixed end of the divider 22 is fixed and disposed on the inner side, while the rotating end of the divider 22 is rotatable and disposed on the outer side of its fixed end, that is, the rotating end of the divider 22 located on the outer side can rotate relative to the fixed end of the divider 22.

[0046] A fixed plate 23 and a rotating plate 24 are fixedly connected to the fixed end on the inner side and the rotating end on the outer side of the divider 22 respectively by bolts. The fixed plate 23 is a circular structure and the rotating plate 24 is an annular structure with a through hole in the middle. The fixed plate 23 is fixed and the rotating end of the divider 22 can drive the rotating plate 24 to rotate. The fixed plate 23 and the rotating plate 24 are coaxially arranged.

[0047] In this embodiment, the divider 22 is a four-station divider, which includes a loading station 25 for loading sensor product 10, a screw-locking station 26 for screwing sensor product 10, a detection station 27 for detecting and photographing the screwed sensor product 10, and a unloading station 28 for unloading sensor product 10.

[0048] Four positioning fixtures 4 are evenly distributed on the rotating disk 24. The four positioning fixtures 4 can rotate with the rotating disk 24 to the loading station 25, the screw-locking station 26, the inspection station 27, and the unloading station 28 in sequence. Among them, the fixed disks 23 at the loading station 25 and the unloading station 28 are respectively fixedly connected to the push cylinders 3. The two push cylinders 3 are respectively facing the positioning fixtures 4 at the loading station 25 and the unloading station 28. The push plate 31 is fixedly connected to the guide rod of the push cylinder 3.

[0049] See appendix Figure 5 , 6 As shown in Figures 7, 8, 9, and 10, the positioning fixture 4 includes a base plate 41 fixedly connected to the rotating disk 24 by bolts. Four columns 411 are vertically fixedly connected to the base plate 41 by bolts. A positioning plate 42 is horizontally fixedly installed on the upper end face of the four columns 411 by bolts. An L-shaped limiting block 43 is fixedly connected to one corner of the upper end face of the positioning plate 42 by bolts. The limiting block 43 has a right-angle bent structure. The inner side of the limiting block 43 faces the inner side of the positioning plate 42. The two sides of the sensor product 10 can abut against the inner side of the limiting block 43.

[0050] A horizontal sliding plate 44 and a vertical sliding plate 45 are slidably mounted on the upper surface of the base plate 41 below the positioning plate 42. In order to make the horizontal sliding plate 44 and the vertical sliding plate 45 slide smoothly on the base plate 41, the horizontal sliding plate 44 and the vertical sliding plate 45 are slidably mounted on the base plate 41 through an existing slider and slide rail assembly. That is, a slider is fixedly connected to the lower surface of the horizontal sliding plate 44 and the vertical sliding plate 45, and a slide rail is fixedly connected to the upper surface of the base plate 41. The slider is slidably embedded in the slide rail.

[0051] It should be noted that the terms "lateral" and "longitudinal" are relative designations. In this embodiment, taking the loading station 25 as an example, the extension and retraction direction of the guide rod parallel to the push cylinder 3 is set as "longitudinal", and the extension and retraction direction of the guide rod perpendicular to the push cylinder 3 is set as "longitudinal". That is, the sliding directions of the lateral slide plate 44 and the longitudinal slide plate 45 are perpendicular to each other.

[0052] L-shaped lateral positioning blocks 441 and L-shaped longitudinal positioning blocks 451 are fixedly connected to the lateral sliding plate 44 and longitudinal sliding plate 45, respectively. The lower parts of the lateral positioning blocks 441 and longitudinal positioning blocks 451 are fixedly connected to the lateral sliding plate 44 and longitudinal sliding plate 45 on the outside of the positioning plate 42, respectively. The upper parts of the lateral positioning blocks 441 and longitudinal positioning blocks 451 are bent towards the inside of the positioning plate 42 and extend above the positioning plate 42. Thus, the limiting block 43 and the upper parts of the lateral positioning blocks 441 and longitudinal positioning blocks 451 enclose a positioning cavity 421, in which the sensor product 10 is positioned.

[0053] In this embodiment, in order to achieve automatic positioning of the sensor product 10 located in the positioning cavity 421, a locking block 452 is fixedly connected to the outer end face of the longitudinal sliding plate 45, and a hook post 453 is fixedly connected to the bottom plate 41 in the sliding direction of the longitudinal sliding plate 45. The hook post 453 is located on the side near the push cylinder 3, and the hook post 453 is arranged opposite to the locking block 452. One end of the longitudinal tension spring 454 is hung on the hook post 453 on the bottom plate 41, and the other end is hung on... On the longitudinal slide plate 45, there is a first locking block 452; on the outer end face of the transverse slide plate 44, there is a second locking block 442; on the bottom plate 41 in the sliding direction of the transverse slide plate 44, there is a second hook post 443. The second hook post 443 is located on the side close to the longitudinal slide plate 45. The second hook post 443 and the second locking block 442 are arranged opposite to each other. One end of the transverse tension spring 444 is hung on the second hook post 443 on the bottom plate 41 and the other end is hung on the second locking block 442 on the transverse slide plate 44.

[0054] Thus, in the initial state, the lateral tension spring 444 and the longitudinal tension spring 454, which are in a stretched state, will pull the lateral positioning block 441 and the longitudinal positioning block 451 on the lateral sliding plate 44 and the longitudinal sliding plate 45, respectively, towards the inside of the positioning plate 42. The sensor product 10 located in the positioning cavity 421 is pushed by the lateral positioning block 441 and the longitudinal positioning block 451 to abut against the limiting block 43. The four sides of the sensor product 10 are abutted by the limiting block 43, the lateral positioning block 441, and the longitudinal positioning block 451, respectively, thereby completing the positioning and fixing of the sensor product 10.

[0055] Since the transverse positioning block 441 and the longitudinal positioning block 451 need to be detached from the sensor product 10 when the sensor product 10 needs to be placed in the positioning cavity 421 and when the sensor product 10 needs to be removed from the positioning cavity 421, relevant structures need to be set so that the transverse positioning block 441 and the longitudinal positioning block 451 move away from the sensor product 10.

[0056] In this embodiment, to achieve the movement of both the transverse positioning block 441 and the longitudinal positioning block 451 outwards from the positioning plate 42 using only one push cylinder 3, a stop block 455 is provided on one end face of the longitudinal sliding plate 45, which is obliquely opposite to the transverse sliding plate 44. The stop block 455 is located on the longitudinal sliding plate 45 near the push cylinder 3 and is integrally formed with the longitudinal sliding plate 45. An inclined surface 456 is provided on the stop block 455, and the inclined surface 456 faces the transverse sliding plate 44, such as... Figure 8 As shown, when viewed from above, the width of the stop block 455 gradually decreases from top to bottom. When the cylinder 3 pushes the longitudinal slide plate 45, the inclined surface 456 can push the transverse slide plate 44 to slide outward to further stretch the transverse tension spring 444, thereby causing both the transverse positioning block 441 and the longitudinal positioning block 451 to move outward to the positioning plate 42.

[0057] In order to make the ramp 456 push the transverse slide 44 more smoothly, a guide wheel 445 is rotatably connected to the transverse slide 44 opposite to the ramp 456. When the push cylinder 3 pushes the longitudinal slide 45, the ramp 456 abuts against the outer circumference of the guide wheel 445, the guide wheel 445 rotates, and the ramp 456 can push the guide wheel 445 to make the transverse slide 44 slide to its outside.

[0058] See Figure 5 As shown, a photoelectric switch bracket 231 is fixedly connected to a fixed plate 23 on one side of the cylinder 3, and a photoelectric switch 232 is fixedly connected to the photoelectric switch bracket 231. The photoelectric switch 232 is positioned facing the positioning cavity 421 of the positioning fixture 4. The photoelectric switch 232 can be an existing SICK photoelectric switch, which can detect whether the sensor product 10 is present in the positioning cavity 421. That is, when the sensor product 10 is placed in the positioning cavity 421, the light signal emitted by the photoelectric switch 232 is blocked. The structure and detection principle of the photoelectric switch 232 are existing technologies and will not be described in detail here.

[0059] Furthermore, a rubber buffer plate 457 is bonded to the end face of the longitudinal slide plate 45 opposite to the push cylinder 3. When the push plate 31 of the push cylinder 3 comes into contact with the buffer plate 457, the impact on the longitudinal slide plate 45 is reduced.

[0060] See Figure 1 , 2As shown, a feeding conveyor mechanism 8 is provided on the support plate 11 near the feeding station 25. The feeding conveyor mechanism 8 includes a conveyor frame 81 fixedly connected to the upper end face of the support plate 11 by bolts, a rotating shaft 82 rotatably connected to the conveyor frame 81, a conveyor belt 83 sleeved on the rotating shaft 82 and rotating with the rotating shaft 82, and a conveyor drive motor 84 fixedly connected to the conveyor frame 81 and driving the rotating shaft 82 to rotate. The connection method and working principle of the conveyor frame 81, rotating shaft 82, conveyor belt 83 and conveyor drive motor 84 are existing technologies and will not be described in detail here.

[0061] Guide plates 85 are bolted to both sides of the upper end of the conveyor frame 81 near the feeding mechanism 5. The right side of the guide plate 85 has a flared structure to facilitate the sensor product 10 entering between the two guide plates 85. A blocking cylinder 86 is vertically fixed to the conveyor frame 81, and a blocking plate 861 is horizontally fixed to the guide rod of the blocking cylinder 86. When the guide rod of the blocking cylinder 86 retracts, the blocking plate 861 can block the sensor product 10 conveyed on the conveyor belt 83. When the guide rod of the blocking cylinder 86 extends, the sensor product 10 can pass under the blocking plate 861.

[0062] A connecting frame 811 is fixedly connected to the conveyor frame 81 on the side away from the blocking cylinder 86 of the feeding mechanism 5. A guide cylinder 87 facing the conveyor belt 83 is horizontally fixedly connected to the connecting frame 811. A guide plate 871 is fixedly connected to the guide rod of the guide cylinder 87. When the guide rod of the guide cylinder 87 extends, the guide plate 871 can push the sensor product 10 on the conveyor belt 83 to abut against the opposite guide plate 85, thereby completing the correction operation of the sensor product 10, that is, preventing the sensor product 10 from tilting between the two guide plates 85.

[0063] A photoelectric switch 232 is installed on the guide plate 85 near the blocking cylinder 86 of the feeding mechanism 5. The photoelectric switch 232 here has the same structure as the photoelectric switch 232 on the photoelectric switch bracket 231. When the photoelectric switch 232 on the guide plate 85 detects the sensor product 10, the guide rod of the blocking cylinder 86 retracts to drive the blocking plate 861 to descend, thereby blocking the sensor product 10 conveyed behind, preventing the sensor product 10 from accumulating and facilitating the transfer of the sensor product 10 by the feeding mechanism 5. When the photoelectric switch 232 on the guide plate 85 detects that the sensor product 10 here has been transferred away, the guide rod of the blocking cylinder 86 extends to drive the blocking plate 861 to rise, thereby conveying the sensor product 10 conveyed behind to the photoelectric switch 232 on the guide plate 85.

[0064] See Figure 1 , 3As shown, in order to transfer the sensor product 10 at the photoelectric switch 232 on the guide plate 85 to the positioning cavity 421 of the positioning fixture 4 at the loading station 25, a loading mechanism 5 is provided on the support plate 11 between the loading station 25 and the loading conveying mechanism 8.

[0065] The feeding mechanism 5 includes a feeding bracket 51 fixedly connected to the support plate 11 and a drive motor assembly horizontally fixedly connected to the feeding bracket 51. The drive motor assembly includes a reducer 52 fixedly connected to the feeding bracket 51 and a rotary motor 53 connected to the reducer 52. The rotary motor 53 can be an existing Hechuan SV-X2MH075A-B2CA servo motor. The reducer 52 can be an existing servo reducer motor PF90-L2-20. A rotating plate 54 is fixedly connected to the output shaft of the reducer 52. A clamping assembly 55 is horizontally fixedly connected to the rotating plate 54. The clamping assembly 55 can be an existing Junduo modular electric gripper EPG40-050. The clamping assembly 55 can clamp or release the sensor product 10.

[0066] See Figure 1 As shown, a screw-locking mechanism 6 is provided on the support plate 11 near the screw-locking station 26. The screw-locking mechanism 6 is the prior art, which is used to automatically lock the sensor product 10 in the positioning fixture 4 at the screw-locking station 26.

[0067] See Figure 11 As shown, this automatic screw fastening line also includes an inspection station 27, which is the next station after the screw fastening station 26. A mounting bracket 91 is provided above the inspection station 27. The mounting bracket 91 can be fixedly installed on the housing (not shown in the figure) of this automatic screw fastening line. The housing is an existing structure, which is fitted onto this automatic screw fastening line. The mounting bracket 91 includes a vertical connecting rod 911 fixed to the housing of this automatic screw fastening line, a horizontal connecting rod 912 horizontally fixedly installed on the vertical connecting rod 911, and a connecting block 913 fixedly installed on the horizontal connecting rod 911.

[0068] A detection camera assembly is vertically and fixedly connected to the connecting block 913. The detection camera assembly may include a camera 92 fixedly connected to the connecting block 913 and a lens 93 mounted on the camera 92. The camera 92 may be an existing MV-CS060-10GM Hikvision 6MP 1 / 1.8 CMOS gigabit Ethernet camera, and the lens 93 may be an existing MVL-MF5028M-8MP Hikvision 8MP 2 / 3-inch 50mm industrial lens. The detection camera assembly can take pictures of the sensor product 10 in the positioning fixture 4 at the detection station 27 below it to identify whether the screws on the sensor product 10 are properly tightened.

[0069] A feeding mechanism 7 is provided on the support plate 11 near the feeding station 28. The feeding mechanism 7 has the same structure as the feeding mechanism 5. It is used to transfer the sensor product 10 with screws already locked in the positioning fixture 4 at the feeding station 28 to the existing finished product conveying mechanism.

[0070] The working principle and process of this embodiment are as follows:

[0071] Install each component according to this instruction manual. Figure 1 As shown;

[0072] 1. The sensor product 10 to be screwed is placed on the conveyor belt 83 and conveyed forward. After being conveyed to the guide cylinder 87, the guide rod of the guide cylinder 87 extends to drive the guide plate 871 to move, so that the guide plate 871 abuts the sensor product 10 against the guide plate 85. When the photoelectric switch 232 on the guide plate 85 senses that there is no sensor product 10 at that position, the guide rod of the blocking cylinder 86 extends. The sensor product 10 is conveyed by the transmission belt 83 through the blocking plate 861 to the photoelectric switch 232 on the guide plate 85. After that, the guide rod of the blocking cylinder 86 descends to its original position.

[0073] 2. The rotary motor 53 drives the rotating plate 54 and the clamping assembly 55 to rotate to one side of the feeding conveyor mechanism 8, and the clamping assembly 55 completes the clamping of the sensor product 10; the guide rod of the push cylinder 3 at the feeding station 25 extends, so that the push plate 31 pushes the longitudinal slide plate 45, and the longitudinal slide plate 45 drives the transverse slide plate 44 to move, so that the transverse positioning block 441 and the longitudinal positioning block 451 move to the outside of the positioning plate 42, thereby increasing the positioning cavity 421; the rotary motor 53 drives the rotating plate 54 and the clamping assembly 55 to rotate to the positioning fixture 4 at the feeding station 25. Inside the positioning cavity 421, the clamping assembly 55 releases the sensor product 10, and the sensor product 10 falls into the positioning cavity 421; the guide rod of the push cylinder 3 at the loading station 25 retracts, so that the push plate 31 is separated from the buffer pad 457. Under the tension of the transverse positioning block 441 and the longitudinal positioning block 451, the transverse tension spring 444 and the longitudinal tension spring 454 move towards the inside of the positioning plate 42, so that the transverse positioning block 441, the longitudinal positioning block 451 and the limiting block 43 press against the four sides of the sensor product 10, thereby completing the positioning and fixing of the sensor product 10.

[0074] 3. The positioning fixture 4 at the loading station 25, where the sensor product 10 has been positioned and fixed, moves to the screw-locking station 26 under the rotation of the rotating disk 24. The screw-locking mechanism 6 completes the screw-locking operation on the sensor product 10. When the screw-locking mechanism 6 is locking the screws on the sensor product 10 at the screw-locking station 26, steps 1 and 2 above can be repeated to achieve reloading at the loading station 25.

[0075] 4. The positioning fixture 4 at the screw-locking station 26 moves to the inspection station 27 under the rotation of the rotating disk 24. The camera 92 of the inspection mechanism 9 located above the inspection station 27 takes a picture of the sensor product 10 with screws already locked at this station, and identifies whether the screws of the sensor product 10 in the picture are properly locked through the existing identification device.

[0076] 5. The positioning fixture 4 at the inspection station 27 moves to the unloading station 28 under the rotation of the rotating disk 24. The rotary motor 53 of the unloading mechanism 7 drives the rotating plate 54 and the clamping assembly 55 to rotate to the unloading station 28. The clamping assembly 55 completes the clamping of the sensor product 10. Then the rotary motor 53 of the unloading mechanism 7 reverses, driving the clamping assembly 55 to reverse to transfer the sensor product 10 to the existing finished product conveying mechanism.

[0077] By repeating the above process, continuous, assembly-line-style loading, screw tightening, testing, and unloading of sensor product 10 can be achieved.

[0078] All technologies not described in this specification are existing technologies, especially the connection and control methods of existing controllers and components such as rotating mechanism 2, pushing cylinder 3, feeding mechanism 5, screw locking mechanism 6, unloading mechanism 7, feeding conveying mechanism 8, and detection mechanism 9, as well as the photo-taking process of camera 92 and the image processing recognition device for the photos. These will not be elaborated here, as long as they can meet the above working process.
