[0019] The following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] In the present invention, unless otherwise stated, the orientation words contained in terms such as "up, down, inside, outside" only represent the orientation of the term in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation to the term.

[0021] Referring to Figures 1 - 7 As shown, an automatic screw assembly mechanism for automobile parts, the automatic assembly mechanism includes: a base 100 and a controller 102 fixedly arranged on the base 100. A workbench 101 is rotatably arranged on the base 100 through a rotating mechanism 500. A plurality of placing plates 104 for fixing automobile parts are arranged on the workbench 101. A vibration feeding part 103 for automatically feeding screws one by one is arranged on the base 100. And a nail feeding mechanism 200 for respectively feeding different specifications of screws onto the corresponding automobile parts placed in the placing plate 104, a tightening mechanism 300 for tightening the screws on the automobile parts, and a positioning and detecting mechanism 400 for detecting the screws on each automobile part after the screw assembly is completed are sequentially and fixedly arranged on the base 100 along the circumferential direction of the workbench 101.

[0022] During use, the automotive parts are placed in the placement tray 104 of the workbench 101 for fixation. The rotating mechanism 500 drives the workbench 101 to rotate, causing the placement tray 104 to pass through each mechanism in sequence. The vibrating feeding part 103 automatically conveys the screws one by one to prepare for subsequent screw feeding. When the placement tray 104 rotates to the screw feeding mechanism 200, the screw feeding mechanism 200 sends screws of different specifications into the corresponding automotive parts placed in the placement tray 104. The workbench 101 continues to rotate, and the placement tray 104 reaches the tightening mechanism 300. The tightening mechanism 300 tightens the screws on the automotive parts. After the screw assembly is completed, the workbench 101 rotates to make the placement tray 104 reach the positioning and detection mechanism 400. The positioning and detection mechanism 400 detects the screws on each automotive part. After the detection is completed, the workbench 101 rotates again to enter the next round of the screw assembly operation process for automotive parts. The entire screw assembly process, from conveying, screw feeding, tightening to detection, is automatically completed by the corresponding mechanisms, reducing manual operation and improving production efficiency.

[0023] Referring to Figure 4 As shown, the screw feeding mechanism 200 includes: a moving part fixedly installed on the base 100 through a first fixing frame 201. An elevating slide rail 205 is fixedly installed on the moving part. A fixing block 206 is slidably sleeved on the elevating slide rail 205. A first clamping jaw 207 for grasping the screws in the vibrating feeding part 103 and sending them onto the automotive parts is fixedly provided on the fixing block 206. The moving part includes: a slide rail 202 fixedly installed on the first fixing frame 201. A sliding seat 203 is slidably sleeved on the slide rail 202. A driving part 204 for driving the sliding seat 203 to move horizontally on the slide rail 202 is provided on the sliding seat 203. The elevating slide rail 205 is fixedly installed on the sliding seat 203.

[0024] In the above solution, when screw feeding is required, the driving part 204 is activated to drive the sliding seat 203 to move horizontally on the slide rail 202, driving the elevating slide rail 205, the fixing block 206 and the first clamping jaw 207 to move together to a position above the vibrating feeding part 103. Subsequently, the fixing block 206 descends along the elevating slide rail 205, and the first clamping jaw 207 grabs the screws. After the grabbing is completed, the fixing block 206 rises. Then the driving part 204 drives the sliding seat 203 to move on the slide rail 202 again, moving the first clamping jaw 207 that grabs the screws to a position above the automotive part. Finally, the fixing block 206 descends along the elevating slide rail 205, and the first clamping jaw 207 accurately sends the screws into the mounting holes of the automotive part.

[0025] Referring to Figures 5 - 6As shown in the figure, the tightening mechanism 300 includes: a second fixing bracket 301 fixedly installed on the base 100. A telescopic rod 302 is fixedly provided on the second fixing bracket 301. The output shaft of the telescopic rod 302 is vertically downward, and a first mounting bracket 303 that slidably penetrates the second fixing bracket 301 is fixedly provided at the top. A tightening member for tightening the screw is rotatably provided in the first mounting bracket 303. The tightening member includes: a rotating shaft 306 that rotatably penetrates the first mounting bracket 303. The rotating shaft 306 is vertically arranged, and a tightening head 307 is fixedly provided at the bottom end. A fixing head 308 for limiting the screw is fixedly provided in the tightening head 307, and a second jaw 309 for clamping screws of different sizes is provided on the circumferential surface of the tightening head 307. A rotating motor 304 is provided on the second fixing bracket 301. The output shaft of the rotating motor 304 is in transmission connection with the rotating shaft 306 through a transmission belt 305.

[0026] When the workbench 101 rotates the automotive parts equipped with screws to the lower part of the tightening mechanism 300, the telescopic rod 302 is activated, and its output shaft extends vertically downward, driving the first mounting bracket 303 to move downward. When the telescopic rod 302 drives the first mounting bracket 303 to descend so that the tightening head 307 approaches the screw on the automotive parts, the second jaw 309 opens, slews the screw, and the fixing head 308 limits the screw; subsequently, the rotating motor 304 is activated, driving the rotating shaft 306 to rotate through the transmission belt 305, and then the tightening head 307 and the second jaw 309 rotate together to tighten the screw on the automotive parts; after the tightening is completed, the rotating motor 304 stops rotating, the second jaw 309 loosens, and the telescopic rod 302 drives the first mounting bracket 303 and the tightening member to rise and reset. The setting of the telescopic rod 302 enables the tightening member to be flexibly adjusted according to the height of the automotive parts, adapting to the tightening requirements of different specifications of automotive parts; the second jaw 309 can clamp screws of different sizes, greatly improving the versatility of the tightening mechanism 300 and being able to adapt to the tightening work of various specifications of screws.

[0027] Refer to Figure 7 As shown in the figure, the positioning and detection mechanism 400 includes: an identification module and a mechanical detection module; the mechanical detection module includes: a second mounting bracket 401 fixedly installed on the base 100. A hydraulic rod 402 is fixedly provided on the second mounting bracket 401. The output shaft of the hydraulic rod 402 is vertically upward, and a mounting plate 403 is fixedly provided at the top. A slide bar 404 that slidably penetrates the second mounting bracket 401 is fixedly installed on the mounting plate 403. A mechanical claw 405 for clamping the screw is fixedly provided on the bottom surface of the slide bar 404.

[0028] In the above solution, after the workbench 101 rotates the automotive parts with the screws assembled to the position below the positioning and detection mechanism 400, the hydraulic rod 402 is activated, and its output shaft extends vertically upward, driving the mounting plate 403 to rise. The mounting plate 403 moves the mechanical claw 405 upward through the sliding rod 404 to approach the screw on the automotive parts. When the mechanical claw 405 reaches the appropriate position, the mechanical claw 405 clamps the screw, and judges whether the screw is assembled in place by sensing physical characteristics such as the tightening degree and position of the screw.

[0029] Referring to Figure 7 As shown, the identification module includes: a visual identification member 406 fixedly installed on the second mounting bracket 401 corresponding to the position of the placement disk 104 for identifying the position of the screw hole on the automotive parts and the state of the screw to be assembled. A display screen 407 electrically connected to the visual identification member 406 is fixedly provided on the base 100, and an alarm 408 is fixedly provided on the display screen 407.

[0030] In the above solution, when the automotive parts rotate to the position of the positioning and detection mechanism 400 with the workbench 101, the visual identification member 406 starts to work, collects and analyzes images of the position of the screw hole on the automotive parts and the state of the screw to be assembled, and judges whether the screw is missing, whether the position is correct, whether there are defects on the surface, etc. The visual identification member 406 transmits the analysis result to the display screen 407 electrically connected to it for display. If an abnormal situation of the screw is detected, the alarm 408 on the display screen 407 emits an alarm to remind the staff to handle it. After the detection is completed, the visual identification member 406 remains on standby, waiting for the detection of the next automotive parts.

[0031] Referring to Figures 1 - 2 As shown, the vibrating feeding member 103 is a vibrating disk type screw feeder fixedly provided on the base 100, and a spiral track is arranged inside the vibrating disk type screw feeder.

[0032] In the above solution, after the vibrating disk type screw feeder is activated, it generates vibration, and the screws inside move upward along the track under the action of the vibration force on the spiral track. During the movement, the screws will be automatically arranged according to the shape and size of the track and be conveyed to the discharge port in a unified posture and direction. The first claw 207 of the screw feeding mechanism 200 grabs the screw at the discharge port to complete the screw feeding preparation.

[0033] Referring to Figure 3 As shown, the rotating mechanism 500 includes: a driving motor 501 fixedly installed on the base 100, a rotating shaft 502 rotatably provided on the base 100, the workbench 101 is fixedly installed at the top of the rotating shaft 502, and the output end of the driving motor 501 is fixedly connected to the rotating shaft 502.

[0034] In the above solution, when it is necessary to rotate the workbench 101, the drive motor 501 is started, and the output shaft drives the rotating shaft 502 fixedly connected thereto to rotate; the rotating shaft 502 drives the workbench 101 fixed to its top end to rotate synchronously, so that the placement tray 104 placed on the workbench 101 sequentially passes through the nail feeding mechanism 200, the tightening mechanism 300, and the positioning and detection mechanism 400.

[0035] Referring Figure 3 As shown, the rotating mechanism 500 further includes: a guide rail 505 fixedly installed on the bottom surface of the workbench 101 and coaxially arranged with the workbench 101. A plurality of groups of brackets 503 are fixedly arranged on the base 100 at intervals along the circumferential direction of the workbench 101, and a roller 504 cooperating with the guide rail 505 is rotatably arranged on each group of brackets 503.

[0036] During the rotation of the workbench 101, the guide rail 505 fixed to its bottom surface rotates synchronously with the workbench 101; the rollers 504 on the plurality of groups of brackets 503 on the base 100 are in rolling contact with the guide rail 505, playing a supporting and guiding role for the workbench 101; the rollers 504 rotate freely under the drive of the guide rail 505, reducing the frictional resistance when the workbench 101 rotates.

[0037] In summary, for an automatic screw assembly mechanism for automotive parts provided by the present invention, during use, the automotive parts are placed in the placement tray 104 of the workbench 101. The rotation mechanism 500 is started by the controller 102, and the driving motor 501 drives the rotating shaft 502 to rotate, causing the workbench 101 to rotate in the circumferential direction. The guide rail 505 cooperates with the rotating rod 504 on the bracket 503 to ensure the stable rotation of the workbench 101 and sequentially convey the parts to each station. The vibrating feeding part 103 vibrates and sorts the screws through the spiral track and conveys them to the discharge port one by one. The driving part 204 drives the sliding seat 203 to move horizontally on the sliding rail 202, aligning the lifting sliding rail 205 with the discharge port of the vibrating feeding part 103. The fixed block 206 descends along the lifting sliding rail 205, and the first clamping jaw 207 grabs the screw at the discharge port. The fixed block 206 rises and resets. The driving part 204 acts again, moving the sliding seat 203 above the placement tray 104. The first clamping jaw 207 releases, and the screw falls into the preset hole of the automotive part. The telescopic rod 302 pushes the first mounting bracket 303 to descend, aligning the tightening head 307 with the top of the screw. The second clamping jaw 309 clamps the head of the screw, and the fixed head 308 provides axial limitation for the screw. The rotating motor 304 drives the rotating shaft 306 and the tightening head 307 to rotate through the transmission belt 305 to complete the screw tightening operation. The telescopic rod 302 drives the tightening head 307 to rise and reset. The visual recognition part 406 captures the position of the screw hole and the state of the screw on the part and transmits the image data to the controller 102. The controller 102 analyzes the data to determine whether the screw is missing, misaligned, or not tightened, and displays the result on the display screen 407. The hydraulic rod 402 pushes the mounting plate 403 to rise, and the mechanical claw 405 clamps the screw for torque detection or position verification. The sliding rod 404 ensures the stable movement of the mechanical claw 405 to avoid damaging the part. If a defective product is detected, the alarm 408 triggers an audible and visual alarm to prompt the operator to intervene.
