With the increasingly high quality requirements for industrial products, high precision of the quality control system and the automation process of detection means are accelerating synchronously and becoming increasingly intelligent.
When the existing similar equipment detects a workpiece, transmission and detection modes of unidirectional entry and exit of the workpiece are adopted. If multi-angle and multi-side detection of workpiece quality such as defects and deficiencies is needed, it needs to complete a unidirectional stroke, collection at an outgoing end, retrieval of the workpiece, rehandling, transfer to an incoming end at the other side, manual adjustment of positions and rolling angles, rearrangement and repetition of the previous detection step. In this case, manpower and time consumption will be increased significantly, and possibly due to the deviation of placement positions, the difficulty of image file defect identification of the same workpiece, detection accuracy and detection efficiency are also greatly affected.
Therefore, under the current situation, it is very necessary to provide a detection system that can reduce equipment floor area and working space, reduce manpower demands and time consumption, improve the detection accuracy and increase the detection efficiency.

It should be understood in the description of the present invention that terms such as “upper”, “lower”, “front”, “rear”, “left”, “right”, “top”, “bottom”, “inner”, “outer”, etc. indicate direction or position relationships shown based on the drawings, and are only intended to facilitate the description of the present invention and the simplification of the description rather than to indicate or imply that the indicated device or element must have a specific direction or constructed and operated in a specific direction, and therefore, shall not be understood as a limitation to the present invention.
The present invention provides an auto-tuning bidirectional scanning X-ray intelligent detection system, comprising a workpiece vehicle 21 and a detection system body 22.
The workpiece vehicle 21 can be used for loading different kinds of workpieces adapted therewith. In the present embodiment, a specific bicycle front fork workpiece 18 is used for illustration. However, it should be emphasized that the workpiece detection range in the system includes but is not limited to the bicycle front fork workpiece 18.
Generally, the bicycle front fork workpiece 18 comprises a hollow standpipe 19 and two fork legs 20 respectively connected to the bottom of the standpipe 19; and the lower ends of the two fork legs 20 are provided with hook jaws connected and fixed with a bicycle hub shaft.
Referring to Fig. 4 to Fig. 7, the workpiece vehicle 21 comprises a vehicle body that can be placed flat on a conveyor belt device 23 of the detection system body 22 for transmission, and the vehicle body comprises a rear side plate 1, a left side plate 2, a right side plate 3 and an adjustable front side plate 4 which can be adjusted back and forth relative to the rear side plate 1.
Specifically, a chute 15 parallel to the axial direction of the corresponding side plate is arranged respectively in the middle positions of the left side plate 2 and the right side plate 3 near one end of the adjustable front side plate 4; two through holes are formed at both ends of the adjustable front side plate 4; the through holes correspondingly penetrate through sliding rods 16 on both sides of the chutes 15 on the left side plate 2 and the right side plate 3; and the adjustable front side plate 4 can slide back and forth relative to the sliding rods 16 (i.e., the left side plate 2 and the right side plate 3) so as to put the bicycle front fork workpiece 18 of different length specifications.
Both ends of the adjustable front side plate 4 are respectively provided with an adjustment screw 17 which can temporarily jack and fix the adjustable front side plate with the left side plate 2 and the right side plate 3, so that after a distance between the rear side plate 1 and the adjustable front side plate 4 is adjusted, the adjustable front side plate 4 may not slide freely, to avoid falling or unsmooth turning due to the influence on the placement of the bicycle front fork workpiece 18 on the workpiece vehicle 21.
The rear side plate 1, the left side plate 2, the right side plate 3 and the adjustable front side plate 4 are enclosed into a rectangular frame; a supporting strip 5 is arranged in the rectangular frame adjacent to an inner wall of the rear side plate 1; both ends of the supporting strip 5 are respectively fixed with the inner walls of the left side plate 2 and the right side plate 3; a plurality of U-shaped slots 6 for supporting and placing a standpipe 19 of the bicycle front fork workpiece 18 are arranged at the top end of the supporting strip 5 at intervals; and the width of the U-shaped slots 6 is slightly larger than the outer diameter of the standpipe 19 of the bicycle front fork workpiece 18, so that the bicycle front fork workpiece 18 can be turned smoothly.
An outer wall of the adjustable front side plate 4 is provided with a parallelogram planar four- bar mechanism 7; an upper bar 8 and a lower bar 9 of the planar four-bar mechanism 7 are parallel to an axial direction of the adjustable front side plate 4, wherein the lower bar 9 can be fixed in a lower position at the outer side wall of the adjustable front side plate 4; the upper bar 8 is arranged above a top surface of the adjustable front side plate 4; and two side bars 10 of the planar four-bar mechanism 7 are hinged with the corresponding ends of the upper bar 8 and the lower bar 9 respectively.
A DC motor 11 is fixed on the outer side wall of the left side plate 2 or the right side plate 3.
Because the workpiece vehicle 21 needs to move in the workpiece vehicle running and detecting channel made of protective material which prevents X-ray leakage, and an electrical signal cannot be transmitted through the channel, the DC motor 11 is selected to control the motion of the plane four-bar mechanism 7.
An output shaft of the DC motor 11 is parallel to the axial direction of the corresponding side plate, and a shaft end of the output shaft is fixed with a gear 12; the bottom of the gear 12 is meshed with a rack 13 parallel to the axial direction of the adjustable front side plate 4; and the rack 13 passes through the chute 15 on the corresponding side plate and is fixedly connected with the corresponding side bar 10 of the side plate.
A plurality of hooks 14 far hooking a hook claw at the end of one fork leg 20 of the bicycle front fork workpiece 18 are fixed on the inner side wall of the upper bar 8 at intervals; and the hooks 14 are consistent with the U-shaped slots 6 in quantity and corresponding to the U-shaped slots in positions.
In other words, the upper bar 8 in the present invention is used as a hook fixing plate, and the side bars 10 are used as pull-lift inclined tie rods.
The working process of the workpiece vehicle 21 in the present invention is:
Firstly, the spacing between the adjustable front side plate 4 and the rear side plate 1 is adjusted according to the specifications of the bicycle front fork workpiece 18 (generally, length is between 60 cm and 90 cm), so that one end of the standpipe 19 of the workpiece is just placed in the corresponding position of the U-shaped slot 6, and the hook claw at the end of the fork leg 20 can be just hooked and pulled tightly by the hook 14 in the corresponding position; and then the adjustable front side plate 4 is temporarily jacked and fixed to the left side plate 2 and the right side plate 3 by using the adjustment screw 17.
When one side of the bicycle front fork workpiece 18 is detected and needs to be turned to a certain angle to detect another side, the DC motor 11 is started by itself by triggering and energizing; the output shaft of the DC motor 11 drives the gear 12 thereon to rotate by a pre-set number of turns; and the gear 12 drives the rack 13 meshed therewith to move, to transfer motion for the side bars 10 fixedly connected with the rack 13. The side bars 10 drive the upper bar 8 hinged therewith to move; the hook 14 on the upper bar 8 has an arc motion trajectory; then all the bicycle front fork workpieces 18 on the workpiece vehicle 21 are driven to turn; and a general turning angle range is 60-75°. If the bicycle front fork workpieces 18 need to turn back to an original state, then the DC motor 11 is triggered to reverse, and the output shaft of the DC motor 11 reverses by the same number of turns.
Referring to Fig. 1 to Fig. 3, the detection system body 22 comprises a conveyor belt device 23, a workpiece vehicle running and detecting channel, a scanning detection device 29, and a turning trigger device 30.
The workpiece vehicle running and detecting channel is fully closed and only opened on one side, and the opening is a workpiece inlet and outlet 24; one end of the conveyor belt device 23 extends into the workpiece vehicle running and detecting channel through the workpiece inlet and outlet 24, and reaches the bottom of the channel.
A part of the conveyor belt device 23 exposed outside the workpiece vehicle running and detecting channel is a workpiece handling region 25; a region close to one side of the workpiece inlet and outlet 24 on the workpiece vehicle running and detecting channel is a lead curtain region 26; a region away from one side of the workpiece inlet and outlet 24 is a turning trigger region 27; a middle section part of the workpiece vehicle running and detecting channel is a scanning detection region 28; the left and right sides of the scanning detection region 28 are respectively communicated with the lead curtain region 26 and the turning trigger region 27; and the scanning detection device 29 is arranged in the scanning detection region 28.
A tail end of the turning trigger region 27 is provided with a turning trigger device 30; the DC motor 11 is provided with a motor switch contact plate matched with the turning trigger device 30; and the motor switch contact plate can be triggered and pulled by the turning trigger device 30 to realize self-start of circuit closing of the DC motor 11.
In a specific embodiment of the present invention, a minimum distance between the turning trigger device 30 and the scanning detection region 28 is greater than the length of the workpiece vehicle 21, so that the DC motor 11 on the workpiece vehicle 21 is triggered to turn the workpiece after the workpiece vehicle 21 completely passes through the scanning detection region 28.
In a specific embodiment of the present invention, a plurality of layers of thin and light lead curtains are hung in the lead curtain region 26 along the advancing direction of the workpiece vehicle 21, so as to avoid affecting the motion of the workpiece vehicle 21 in the lead curtain region 26 while isolating ray leakage.
A conveyor belt in the conveyor belt device 23 is driven by a conveyor belt deceleration motor for positive rotation, reversal rotation and stop, and the conveyor belt deceleration motor is electrically connected with a PLC control system. The PLC control system may calculate the advancing time of the workpiece vehicle 21 according to the speed of the conveyor belt in the conveyor belt device 23, so that after the motor switch contact plate on the DC motor 11 is triggered and pulled, the conveyor belt deceleration motor controls the conveyor belt to stop working according to the pre-set condition. After the workpiece on the workpiece vehicle 21 is turned, the conveyor belt deceleration motor is started in time according to the pre-set condition to control the conveyor belt to reverse.
The scanning detection device 29 comprises a scanning imaging system and an Al recognition system electrically connected and operated synchronously with the scanning imaging system. The Al recognition system is operated synchronously with a scanning imaging system to identify and label defects.
In a specific embodiment of the present invention, an infrared device can be further arranged respectively at a junction between the scanning detection region 28 and the lead curtain region 26 and a junction between the scanning detection region 28 and the turning trigger region 27; infrared rays emitted by the infrared devices detect the workpiece vehicle 21 passing through the scanning detection region 28 and can trigger the scanning detection device 29 to work continuously during a period when the workpiece vehicle 21 passes through. The infrared devices can make the scanning detection device 29 started only during a period when the workpiece vehicle 21 passes through the scanning detection region 28, and not started at other times, so as to reduce energy consumption.
The working process of the system of the present invention is: 1. The workpiece vehicle 21 loads the workpiece and places the workpiece on the workpiece handling region 25 of the conveyor belt device 23. As shown in Fig. 2, the conveyor belt moves to the left, and brings the workpiece vehicle 21 into the workpiece vehicle running and detecting channel 1 from the workpiece inlet and outlet 24. 2. The workpiece vehicle 21 enters the scanning detection region 28 through the lead curtain region 26, and triggers the scanning imaging system through the infrared devices to start a scanning program for front scanning (plain scanning) operation; 3. The workpiece vehicle 21 completely passes through the scanning detection region 28 and reaches the bottom of the workpiece vehicle running and detecting channel 21. The motor switch contact plate of the DC motor 11 on the workpiece vehicle 21 is triggered and pulled by the turning trigger device 30; the motor is energized and self-started; and the DC motor 11 drives all the bicycle front fork workpieces 18 to turn by 60-75°. 4. The conveyor belt also temporarily stops moving due to the start of a pre-set control program.
The workpiece vehicle 21 stays for 3-5 seconds. After all the bicycle front fork workpieces 18 complete rollover, the conveyor belt moves in reverse according to a command of the control program and brings the workpiece vehicle 21 back to the scanning detection region 28. 5. The workpiece vehicle reaches the scanning detection region 28; the scanning imaging system is triggered through the infrared devices; and the scanning program is started for conducting side scanning (sidewise scanning) operation. 6. The workpiece vehicle 21 completely passes through the scanning detection region 28 and the lead curtain region 26, and is transmitted out from the workpiece inlet and outlet 24, to complete the scanning program. 7. The Al recognition system is operated synchronously with the scanning imaging system to identify and label defects. 8. A plurality of workpiece vehicles are operated synergistically. No. 1 workpiece vehicle enters a detection room, and No. 2 workpiece vehicle loads the workpiece at one side of the workpiece handling region 25. 9.
