Description

Technical Field

[0001] The present invention relates to the technical field of workpiece detection, and more specifically, to an automatic flipping two-way scanning X-ray intelligent detection system. Background Art

[0002] With the increasing quality requirements for industrial products, the high precision of the quality control system and the automation process of the detection means are accelerating synchronously and becoming more and more intelligent.

[0003] When detecting workpieces with existing similar equipment, a one-way in-and-out workpiece transfer and detection method is adopted. If it is necessary to detect the quality conditions such as defects and flaws of the workpiece from multiple angles and sides, it is necessary to complete the one-way travel, collect the workpiece at the out-feed end, retrieve the workpiece, and then perform secondary handling, transfer it to the in-feed end on the other side, manually adjust the position and tilting angle, re-place it, and then repeat the previous detection step. In this case, the consumption of manpower and time will increase significantly, and due to the deviation of the placement position, the difficulty of defect identification of the image file of the same workpiece will increase, and the detection accuracy and detection efficiency will also be greatly affected at the same time.

[0004] Therefore, under the current situation, it is very necessary to provide a detection system that reduces the floor area and working space of the equipment, reduces the manpower requirement and time consumption, improves the detection accuracy, and enhances the detection efficiency. Summary of the Invention

[0005] In view of this, the present invention proposes an automatic flipping two-way scanning X-ray intelligent detection system, and its specific technical solution is as follows:

[0006] An automatic flipping two-way scanning X-ray intelligent detection system includes a workpiece cart and a detection system main body;

[0007] The workpiece vehicle includes a vehicle body that can be placed flat on the conveyor belt device of the detection system main body for conveyance. The vehicle body further includes a rear side plate, a left side plate, a right side plate, and an adjustable front side plate that can be adjusted back and forth relative to the rear side plate. The rear side plate, the left side plate, the right side plate, and the adjustable front side plate together enclose a rectangular frame. A support bar is provided at a position adjacent to the inner wall of the rear side plate inside the rectangular frame. Both ends of the support bar are fixed to the inner walls of the left side plate and the right side plate respectively, and several U-shaped grooves for supporting and placing the vertical pipe at one end of the workpiece are spaced apart at the top of the support bar. A planar four-bar mechanism in the shape of a parallelogram is provided on the outer wall of the adjustable front side plate. Both the upper rod and the lower rod of the planar four-bar mechanism are parallel to the axial direction of the adjustable front side plate. The lower rod is fixed at a lower position on the outer side wall of the adjustable front side plate, and the upper rod is provided above the top surface of the adjustable front side plate. The two side rods of the planar four-bar mechanism are respectively hinged to the corresponding ends of the upper rod and the lower rod. A DC motor is fixed on the outer side wall of the left side plate or the right side plate. The output shaft of the DC motor is parallel to the axial direction of the corresponding side plate, and a gear is fixed at the shaft end of the output shaft. The bottom of the gear meshes with a rack parallel to the axial direction of the adjustable front side plate. The rack passes through the corresponding side plate and is fixedly connected to the side rod corresponding to this side plate. Several hooks for hooking the other end of the workpiece are spaced and fixed on the inner side wall of the upper rod. The number of hooks is the same as the number of U-shaped grooves and the positions correspond to each other.

[0008] The detection system main body includes a conveyor belt device, a workpiece vehicle travel detection channel, a scanning detection device, and a flipping trigger device. The workpiece vehicle travel detection channel is fully enclosed with only one side open, and this opening is the inlet and outlet for workpieces. One end of the conveyor belt device extends into the workpiece vehicle travel detection channel from the inlet and outlet and reaches the bottom of the channel. The part of the conveyor belt device exposed outside the workpiece vehicle travel detection channel is the workpiece loading and unloading area. The area near the inlet and outlet of the workpiece vehicle travel detection channel is the lead curtain area, and the area far from the inlet and outlet is the flipping trigger area. The middle part of the workpiece vehicle travel detection channel is the scanning detection area. The left and right of the scanning detection area are respectively connected to the lead curtain area and the flipping trigger area. The scanning detection device is provided in the scanning detection area. A flipping trigger device is installed at the end of the flipping trigger area. A motor switch contact piece cooperating with the flipping trigger device is provided on the DC motor. The motor switch contact piece can be triggered and toggled by the flipping trigger device to achieve the circuit closing and self-starting of the DC motor.

[0009] By adopting the above technical solutions, the DC motor on the workpiece vehicle of the present invention can transmit motion to the side rod in the planar four-bar mechanism, enabling the upper rod in the planar four-bar mechanism to move in the plane. Furthermore, the hooks on the upper rod have an arc-shaped motion trajectory, driving the workpiece to be automatically flipped. Moreover, the adjustable front side plate in the vehicle body of the workpiece vehicle can be adjusted back and forth relative to the rear side plate, enabling the space between the rear side plate and the adjustable front side plate to adapt to the placement and positioning requirements of workpieces of various specifications and different models, and completing the scanning detection operations of different workpieces.

[0010] The workpiece cart loaded with the workpiece is placed on the conveyor device of the main body of the detection system, enters the workpiece cart walking detection channel from the entry and exit port, enters the scanning detection area through the lead curtain area for front (or side) scanning, and the workpiece cart completely passes through the scanning detection area and arrives at the flip trigger area (or flip trigger device) at the bottom of the workpiece cart walking detection channel. The motor switch contact of the DC motor on the workpiece cart is triggered and toggled by the flip trigger device, and the motor is powered on and starts automatically; at this time, the conveyor system is also started due to the preset control program and temporarily stops moving; the DC motor drives the planar four-bar mechanism to drive the workpiece to flip, and then the conveyor device moves in the opposite direction according to the control program instructions, and brings the workpiece cart back to the scanning detection area for side (or front) scanning. Finally, the workpiece cart completely passes through the scanning detection area and the lead curtain area, arrives at the entry and exit port to unload the workpiece, and the scanning program is completed.

[0011] The entire detection system of the present invention realizes automatic flipping of the workpiece and automatic scanning of the front and side surfaces of the workpiece. The entire scanning process is completed at one time with the cooperation of a conveyor belt device that can rotate forward and reverse and a workpiece vehicle that can automatically flip the workpiece. There is no need to manually carry and reset the workpiece back and forth, nor is there any need to add additional conveying lines. This not only reduces the equipment's footprint and working space, but also reduces manpower requirements and time consumption, greatly improving detection efficiency and detection accuracy.

[0012] Preferably, a sliding groove parallel to the axial direction of the corresponding side plate is provided at the middle position of the left side plate and the right side plate near one end of the adjustable front side plate, and two through holes are provided at both ends of the adjustable front side plate, and the through holes correspond to the sliding rods passing through the two sides of the sliding groove on the left side plate and the right side plate; the two ends of the adjustable front side plate are also respectively installed with an adjustment screw that can temporarily tighten and fix it to the left side plate and the right side plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0031] Embodiment:

[0032] An automatic flipping two-way scanning X-ray intelligent detection system of the present invention includes a workpiece cart 21 and a detection system main body 22.

[0033] The workpiece cart 21 can be used to load different types of workpieces adapted thereto. In this embodiment, a specific bicycle front fork workpiece 18 is used for illustration. However, it should be emphasized that the workpiece detection range of this system includes but is not limited to the bicycle front fork workpiece 18.

[0034] Generally speaking, the bicycle front fork workpiece 18 includes a hollow vertical tube 19 and two fork legs 20 respectively connected to the bottom of the vertical tube 19. Hook claws for connecting and fixing the bicycle hub shaft are provided at the lower ends of the two fork legs 20.

[0035] Refer to Figures 4 - 7 , the workpiece cart 21 includes a vehicle body that can be placed flat on the conveyor belt device 23 of the detection system main body 22 for conveyance. The vehicle body includes a rear side plate 1, a left side plate 2, a right side plate 3, and an adjustable front side plate 4 that can be adjusted back and forth relative to the rear side plate 1.

[0036] Specifically, middle positions at one ends of the left side plate 2 and the right side plate 3 close to the adjustable front side plate 4 are each provided with a chute 15 parallel to the axial direction of the corresponding side plate. At the same time, two through holes are provided at both ends of the adjustable front side plate 4. The through holes correspondingly pass through the slide rods 16 on both sides of the chute 15 on the left side plate 2 and the right side plate 3, so that the adjustable front side plate 4 can slide back and forth relative to the slide rods 16 (that is, the left side plate 2 and the right side plate 3) to cooperate with the placement of bicycle front fork workpieces 18 of different length specifications.

[0037] At both ends of the adjustable front side plate 4, an adjusting screw 17 is respectively installed, which can temporarily tighten and fix it to the left side plate 2 and the right side plate 3. So that after the distance between the rear side plate 1 and the adjustable front side plate 4 is adjusted, the adjustable front side plate 4 will not slide randomly, avoiding the placement of the bicycle front fork workpiece 18 on the workpiece carrier 21 from being affected, such as falling or having poor flipping.

[0038] The rear side plate 1, the left side plate 2, the right side plate 3 and the adjustable front side plate 4 together enclose a rectangular frame; a support bar 5 is provided at a position adjacent to the inner wall of the rear side plate 1 inside the rectangular frame. The two ends of the support bar 5 are respectively fixed to the inner walls of the left side plate 2 and the right side plate 3, and several U-shaped grooves 6 for supporting and placing the vertical pipes 19 of the bicycle front fork workpiece 18 are spaced apart at the top of the support bar 5. The width of the U-shaped groove 6 is slightly larger than the outer diameter of the vertical pipe 19 of the bicycle front fork workpiece 18, so that the bicycle front fork workpiece 18 can be flipped smoothly.

[0039] A planar four-bar mechanism 7 in the shape of a parallelogram is provided on the outer wall of the adjustable front side plate 4. The upper rod 8 and the lower rod 9 of the planar four-bar mechanism 7 are both parallel to the axial direction of the adjustable front side plate 4. Among them, the lower rod 9 is fixed at the lower position of the outer side wall of the adjustable front side plate 4, and the upper rod 8 is arranged above the top surface of the adjustable front side plate 4. The two side rods 10 of the planar four-bar mechanism 7 are respectively hinged to the corresponding ends of the upper rod 8 and the lower rod 9.

[0040] A DC motor 11 is fixed on the outer side wall of the left side plate 2 or the right side plate 3. In view of the fact that the workpiece carrier 21 has to move in the workpiece carrier walking detection channel made of a protective material for preventing X-ray leakage, and the electrical signal cannot be transmitted through the channel, therefore, the DC motor 11 is selected to control the movement of the planar four-bar mechanism 7.

[0041] The output shaft of the DC motor 11 is parallel to the axial direction of the corresponding side plate, and a gear 12 is fixed at the shaft end of the output shaft. The bottom of the gear 12 meshes with a rack 13 parallel to the axial direction of the adjustable front side plate 4. The rack 13 passes through the sliding groove 15 on the corresponding side plate and is fixedly connected to the corresponding side rod 10 of the side plate.

[0042] Several hooks 14 for hooking the end claws of one of the fork legs 20 of the bicycle front fork workpiece 18 are spaced and fixed on the inner side wall of the upper rod 8. The number of the hooks 14 is the same as the number of the U-shaped grooves 6 and the positions correspond to each other.

[0043] In other words, in the present invention, the upper rod 8 is used as a hook fixing plate, and the side rod 10 is used as a lifting inclined pull rod.

[0044] The working process of the workpiece carrier 21 of the present invention is as follows:

[0045] First, adjust the distance between the adjustable front side plate 4 and the rear side plate 1 according to the specifications of the bicycle front fork workpiece 18 (generally with a length between 60 and 90 cm), so that one end of the vertical tube 19 of the workpiece just rests in the U-shaped groove 6 at the corresponding position, and the hook at the end of the fork leg 20 can just be hooked and tightened by the hook 14 at the corresponding position. Then, temporarily fix the adjustable front side plate 4 on the left side plate 2 and the right side plate 3 by using the adjusting screw 17.

[0046] When it is necessary to flip the bicycle front fork workpiece 18 by a certain angle to detect the other side after detecting one side, the DC motor 11 is triggered to start automatically by power-on. The output shaft of the DC motor 11 drives the gear 12 on it to rotate a preset number of turns. The rotation of the gear 12 drives the rack 13 meshing with it to move, and further transmits the motion to the side rod 10 fixed to the rack 13. The side rod 10 then drives the upper rod 8 hinged to it to move, so that the hook 14 on the upper rod 8 has an arc-shaped movement trajectory, and further drives all the bicycle front fork workpieces 18 on the workpiece cart 21 to flip. Generally, the flipping angle range is 60 to 75°. If it is necessary to flip the bicycle front fork workpiece 18 back to its original state, trigger the DC motor 11 to reverse, and the output shaft of the DC motor 11 reverses the same number of turns.

[0047] Refer to Figures 1 - 3 , the detection system main body 22 includes a conveyor belt device 23, a workpiece cart walking detection channel, a scanning detection device 29, and a flipping trigger device 30.

[0048] The workpiece cart walking detection channel is fully enclosed with only one side open, and this opening is the workpiece inlet and outlet 24. One end of the conveyor belt device 23 extends into the workpiece cart walking detection channel from the workpiece inlet and outlet 24 and reaches the bottom of the channel.

[0049] The part of the conveyor belt device 23 exposed outside the workpiece cart walking detection channel is the workpiece loading and unloading area 25; the area near the workpiece inlet and outlet 24 of the workpiece cart walking detection channel is the lead curtain area 26, and the area far from the workpiece inlet and outlet 24 is the flipping trigger area 27. The middle part of the workpiece cart walking detection channel is the scanning detection area 28. The left and right of the scanning detection area 28 are respectively connected to the lead curtain area 26 and the flipping trigger area 27, and the scanning detection device 29 is arranged in the scanning detection area 28.

[0050] The flipping trigger device 30 is installed at the end of the flipping trigger area 27. The DC motor 11 is provided with a motor switch contact piece that cooperates with the flipping trigger device 30, and the motor switch contact piece can be triggered and toggled by the flipping trigger device 30 to realize the circuit closing and self-starting of the DC motor 11.

[0051] In a specific embodiment of the present invention, the shortest distance between the flipping trigger device 30 and the scanning detection area 28 is greater than the length of the workpiece cart 21, so that after the workpiece cart 21 completely passes through the scanning detection area 28, the DC motor 11 thereon is triggered to flip the workpiece.

[0052] In a specific embodiment of the present invention, multiple layers of thin and light lead curtains are vertically hung along the traveling direction of the workpiece cart 21 in the lead curtain area 26 to isolate the leakage of rays and avoid affecting the movement of the workpiece cart 21 in the lead curtain area 26 at the same time.

[0053] The conveyor belt in the conveyor belt device 23 is driven by a conveyor belt reduction motor to rotate forward, reverse, and stop. The conveyor belt reduction motor is electrically connected to the PLC control system. The PLC control system calculates the traveling time of the workpiece cart 21 according to the rotation speed of the conveyor belt in the conveyor belt device 23, so that after the motor switch contact on the DC motor 11 is triggered and toggled, the conveyor belt reduction motor stops the conveyor belt from working according to the preset. When the workpiece on the workpiece cart 21 is flipped over, the conveyor belt reduction motor starts in time according to the preset to control the conveyor belt to move in the reverse direction.

[0054] The scanning detection device 29 includes a scanning imaging system and an AI recognition system that is electrically connected to the scanning imaging system and operates synchronously. The AI recognition system operates synchronously with the scanning imaging system to identify defects and mark them.

[0055] In a specific embodiment of the present invention, an infrared device can be further provided at the junction of the scanning detection area 28 and the lead curtain area 26 and at the junction of the scanning detection area 28 and the flipping trigger area 27 respectively. The infrared rays emitted by the infrared device detect the workpiece cart 21 passing through the scanning detection area 28 and can trigger the scanning detection device 29 to continuously work during the period when the workpiece cart 21 passes through. The infrared device can enable the scanning detection device 29 to start only during the period when the workpiece cart 21 passes through the scanning detection area 28 and not start at other times to reduce energy consumption.

[0056] The working process of the system of the present invention is as follows:

[0057] 1. The workpiece cart 21 is loaded with workpieces and placed on the workpiece loading and unloading area 25 of the conveyor belt device 23; as Figure 2 shown, the conveyor belt moves to the left, and the workpiece cart 21 is brought into the workpiece cart walking detection channel from the workpiece inlet and outlet 24.

[0058] 2. The workpiece cart 21 enters the scanning detection area 28 through the lead curtain area 26, triggers the scanning imaging system through the infrared device, starts the scanning program, and performs the front scanning (flat scanning) operation.

[0059] 3. The workpiece carrier 21 completely passes through the scanning detection area 28 and reaches the bottom of the walking detection channel of the workpiece carrier. The motor switch contact of the DC motor 11 on the workpiece carrier 21 is triggered and toggled by the flipping trigger device 30, and the motor is powered on and starts automatically. The DC motor 11 drives all the front fork workpieces 18 of the bicycle to flip by 60 - 75°;

[0060] 4. The conveyor belt is also started due to the preset control program and temporarily stops moving. The workpiece carrier 21 stays for 3 - 5 seconds. After all the front fork workpieces 18 of the bicycle complete the side flip, the conveyor belt moves in the reverse direction according to the control program instructions and brings the workpiece carrier 21 back to the scanning detection area 28 again;

[0061] 5. When reaching the scanning detection area 28, the infrared device triggers the scanning imaging system, starts the scanning program, and performs side scanning (lateral scan) operations;

[0062] 6. The workpiece carrier 21 completely passes through the scanning detection area 28 and the lead curtain area 26 and is transported out through the inlet / outlet 24, and the scanning program is completed;

[0063] 7. The AI recognition system operates synchronously with the scanning imaging system to identify defects and mark them;

[0064] 8. Multiple workpiece carriers cooperate in operations. The No. 1 workpiece carrier enters the detection room, and the No. 2 workpiece carrier loads workpieces beside the workpiece loading / unloading area 25;

[0065] 9. After the No. 1 workpiece carrier completes the front and side scanning operations and returns to the workpiece loading / unloading area 25, the No. 2 workpiece carrier timely changes positions, enters the conveyor belt, and starts the next vehicle's scanning and detection operations.

[0066] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
