[0023] The utility model is further described below in combination with specific embodiments, and it should be understood that these embodiments are only used to illustrate the utility model and not used to limit the protection scope of the utility model.

[0024] The embodiments of the utility model are described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the utility model from the disclosure of the specification. The utility model can also be implemented or applied through other different embodiments, and various modifications or changes can be made to the details in the specification based on different viewpoints and applications without departing from the spirit of the utility model.

[0025] Referring to Figures 1-4 A double-end bolt orientation device comprises an orientation plate 300, two detection heads 301, two clamping heads 302, and the two detection heads 301 are arranged to be close to or away from each other simultaneously, the opposite end faces of the two detection heads 301 are arc-shaped detection faces, and the curvature radius of the arc-shaped detection faces matches the outer contour of the bend segment of the U-shaped double-end bolt, the two detection heads 301 are arranged between the two clamping heads 302, and the two clamping heads 302 are arranged to be close to or away from each other simultaneously.

[0026] In the embodiment, when the bend segment of the U-shaped double-end bolt passes through the direction detection mechanism in the correct direction, the bend segment extrudes the two detection heads 301 to move away from each other, allowing the U-shaped double-end bolt to pass through; when the open segment of the U-shaped double-end bolt enters in the reverse direction, the two detection heads 301 are embedded in the open segment and are locked, and the two detection heads 301 ensure that the detection heads 301 can be closely attached to the bend segment when the bend segment of the U-shaped double-end bolt passes through the detection heads 301 in the correct direction, so as to generate sufficient extrusion force to move the detection heads 301 to both sides. At the same time, when the open segment of the U-shaped double-end bolt passes through the detection heads 301, the detection heads 301 can smoothly fall into the inside of the open segment and will not generate excessive resistance, when the detection heads 301 detect that the direction of the U-shaped double-end bolt is incorrect, the two clamping heads 302 are close to each other and clamp the bolt simultaneously, the bolt is rotated 180° through the orientation plate 300, and the direction of the bolt is correct. Finally, the clamping heads 302 release the bolt, and the bolt continues to advance along the conveying table 100.

[0027] The orientation plate 300 comprises two moving grooves 304, two moving grooves 304 are formed on the orientation plate 300, two moving blocks 305, the moving blocks 305 are connected in the moving grooves 304, the detection head 301 is installed on the moving blocks 305, an elastic member 306, one end of the elastic member 306 is connected to the inner wall of the moving groove 304, and the other end of the elastic member 306 is connected to the moving block 305, a pressure sensor 307 is installed on the inner wall of the moving groove 304, and a second power source 303 is installed on the orientation plate 300, and the power shaft of the second power source 303 is connected with the orientation plate 300.

[0028] The opening accuracy and surface flatness of the moving groove 304 are crucial for the smooth movement of the detection head 301. The width and depth of the moving groove 304 are accurately designed according to the size of the moving block 305 and the movement range of the detection head 301, so that the moving block 305 can smoothly slide in the groove without jamming or shaking. The moving block 305 and the moving groove 304 adopt a suitable fit tolerance, which ensures the flexibility of the moving block 305 in the moving groove 304 and prevents the moving block 305 from generating too large a gap during movement, which may cause the position deviation of the detection head 301. The elastic member 306 is usually a spring, and its elastic coefficient is carefully calculated and selected. When the detection head 301 is subjected to external force, the elastic member 306 will be elastically deformed and store energy. When the external force disappears, the elastic member 306 will return to its original state, so that the detection head 301 returns to the initial position. The presence of the elastic member 306 enables the detection head 301 to produce corresponding displacement according to different parts of the U-shaped double-headed bolt during detection, and ensures that the detection head 301 can be accurately reset after each detection, preparing for the next detection.

[0029] The pressure sensor 307 mainly detects the pressure change of the moving block 305 to the inner wall of the moving groove 304 during movement. When the opening part of the U-shaped double-headed bolt passes through the detection head 301, the detection head 301 is subjected to the extrusion of the U-shaped double-headed bolt, and the pressure is transmitted to the pressure sensor 307. The pressure sensor 307 converts the pressure signal into an electric signal and transmits it to the control system. The control system judges whether the direction of the U-shaped double-headed bolt is correct according to the received pressure signal. The second power source 303 adopts a pneumatic cylinder, and a linear motor can also be used.

[0030] The conveying table 100, the orientation plate 300 is arranged above the conveying table 100, and the conveying table 100 is used for conveying the U-shaped double-headed bolt. The conveying table 100 comprises a support frame 200 installed on the conveying table 100, and the orientation plate 300 is installed on the support frame 200. The support frame 200 comprises a first power source 201 installed on the support frame 200, and the power shaft of the first power source 201 is connected with the orientation plate 300.

[0031] The support frame 200 plays a role of supporting and fixing the orientation plate 300, ensuring that the orientation plate 300 remains stable during operation, and the first power source 201 adopts a servo motor, and can also adopt a stepping motor, and the first power source 201 is used to drive the orientation plate 300 to rotate.

[0032] In use, the U-shaped double-end bolt to be oriented is placed on the conveying table 100, and the conveying is ready to start. The conveying table 100 starts to convey the U-shaped double-end bolt to move to the detection area below the orientation plate 300. If the bent section of the U-shaped double-end bolt passes through the detection head 301 in the forward direction, the bent section will extrude the two detection heads 301. The detection heads 301 move away from each other in the moving groove 304 by overcoming the resistance of the elastic member 306, allowing the U-shaped double-end bolt to continue to pass through the detection area.

[0033] If the open section of the U-shaped double-end bolt enters the detection head 301 in the reverse direction, the two detection heads 301 will be embedded in the open section and locked. The detection head 301 is extruded by the U-shaped double-end bolt, which transmits the pressure to the pressure sensor 307. The pressure sensor 307 converts the pressure signal into an electrical signal and transmits it to the control system. The control system determines that the direction of the U-shaped double-end bolt is incorrect according to the received pressure signal, and triggers the subsequent adjustment action.

[0034] When the control system determines that the direction of the bolt is incorrect, the two clamping heads 302 simultaneously approach and clamp the bolt. The first power source 201 is started, and the orientation plate 300 is driven to rotate by the power shaft, thereby rotating the clamped bolt by 180° to make its direction correct. After the direction of the bolt is adjusted correctly, the clamping head 302 releases the bolt, and the bolt continues to advance along the conveying table 100, completing the orientation process.

[0035] Compared with the prior art, the present application has the following beneficial effects:

[0036] By adopting two detection heads 301, the direction of the U-shaped double-end bolt can be accurately determined according to the interaction between different parts of the U-shaped double-end bolt and the detection head 301, and the accurate identification of the direction of the U-shaped double-end bolt is realized.

[0037] The two clamping heads 302 can quickly and simultaneously approach and clamp the bolt, and the bolt is rotated by 180° by the first power source 201 to make its direction correct, ensuring that the U-shaped double-end bolt can enter the subsequent assembly link with the correct posture, and improving the production efficiency of the automatic production line.
