[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] As Figures 2 to 3 shown, an automatic detection device for automobile seat ducts includes a machine hood 1, an equipment control panel 2, a workbench 3, a feeding seat 4, a feeding conveyor assembly 5, a feeding manipulator 6, a feeding positioning detection device 7, a spring detection device 8, a stainless steel sheet detection device 9, a button and spring pressing detection device 10, a material moving device 11, a defective product discharging device 12, a dotting device 13, an output conveyor belt 14 and a good product collection box 15. The feeding seats 4 are symmetrically arranged on the workbench 3. A feeding guide rail 41 for conveying the automobile seat ducts 16 is provided on the feeding seat 4. The equipment control panel 2 is installed on the machine hood 1, and the machine hood 1 is installed on the workbench 3. The equipment control panel 2 is used to control the start and stop of the whole equipment, record the number of good products and production numbers of the automobile seat ducts 16, and also has functions such as resetting the equipment.

[0032] As Figure 4As shown in the figure, the feeding conveyor assembly 5 is arranged at the feeding port of the feeding guide rail 41 and is used to convey the automotive seat conduit 16 to the lower part of the feeding manipulator 6. The feeding manipulator 6 is installed on the material moving device 11 and is used to move the automotive seat conduit 16 to the feeding positioning detection device 7. The feeding positioning detection device 7 is arranged on the front side of the feeding seat 4 and is used to detect whether the automotive seat conduit 16 fed by the feeding manipulator is in place. The material moving device 11 is arranged on the rear side of the feeding seat 4. The spring detection device 8 and the stainless steel sheet detection device 9 are sequentially arranged on the front side of the feeding seat 4 according to the detection process. The material moving device 11 is used to convey the automotive seat conduit 16 along the feeding guide rail 41 to the spring detection device 8. The spring detection device 8 is used to detect whether there is a mounting spring 161 in the automotive seat conduit 16. Then, the material moving device 11 continues to convey the automotive seat conduit 16 along the feeding guide rail 41 to the stainless steel sheet detection device 9. The stainless steel sheet detection device 9 is used to detect whether there is a mounting stainless steel sheet 162 in the automotive seat conduit 16. The button and spring pressing detection device 10 is arranged behind the stainless steel sheet detection device 9 and is used to perform a pressing detection on the button 163 and the spring 161 of the automotive seat conduit 16. Then, the material moving device 11 can continue to convey the automotive seat conduit 16 along the feeding guide rail 41 to the defective product discharging device 12. The defective product discharging device 12 can discharge the defective products detected in the previous detection process. The non-defective products continue to be conveyed along the feeding guide rail 41 to the dotting device 13 through the material moving device 11. The dotting device 13 is used to make dotting marks on the automotive seat conduit 16. Finally, the material moving device 11 continues to convey the automotive seat conduit 16 along the feeding guide rail 41 to the discharging conveyor belt 14. The discharging conveyor belt 14 is arranged at the discharging end of the feeding seat 4 and can convey the automotive seat conduit 16 into the non-defective product collection box 15.

[0033] In this embodiment, as Figure 5 shown, the feeding conveyor assemblies 5 are symmetrically arranged between the two feeding seats 4 respectively. Each group of feeding conveyor assemblies 5 has the same structure. Now, one of the groups will be described in detail. One of the groups of feeding conveyor assemblies 5 includes a motor 51, a conveyor belt 52 and belt pulleys 53. The motor 51 can drive the conveyor belt 52 to perform a conveying movement through the belt pulleys 53. There are 4 belt pulleys 53, and the conveyor belt 52 is sequentially wound around these 4 belt pulleys 53. The motor 51 drives one of the belt pulleys 53 to rotate, thereby driving the conveyor belt 52 to rotate. In this way, the automotive seat conduit 16 placed on the conveyor belt 52 will move along with the movement of the conveyor belt 52.

[0034] In this embodiment, as Figure 6 and Figure 7As shown, the feeding manipulator 6 includes a feeding hook 61, a first mounting seat 62, and a first lifting cylinder 63. The first lifting cylinder 63 is mounted on the first mounting seat 62, and the first mounting seat 62 is mounted on the left side of the material moving device 11. The feeding hook 61 is connected to the first lifting cylinder 63, and the first lifting cylinder 63 can drive the feeding hook 61 to move up and down. The entire feeding manipulator 6 is mounted on the lifting plate 1122 of the material moving device 11, so that the material moving device 11 can synchronously drive the feeding hook 61 to move up and down and left and right. In this embodiment, the feeding hook 61 is mounted on the material moving device 11, which can simplify the driving structure of the feeding hook 61 and enable the feeding hook 61 to achieve synchronous conveying movement with the material moving device 11.

[0035] In this embodiment, the feeding positioning detection device 7 is a fiber optic sensor. The fiber optic sensor is a sensor that converts the state of the measured object into a measurable optical signal. The working principle of the fiber optic sensor is to send the light beam incident from the light source into the modulator through the optical fiber. In the modulator, it interacts with the external measured parameter, causing the optical properties of the light, such as the intensity, wavelength, frequency, phase, polarization state, etc., to change, becoming the modulated optical signal. Then, it is sent through the optical fiber to the optoelectronic device and, after passing through the demodulator, the measured parameter is obtained. During the whole process, the light beam is introduced through the optical fiber and then emitted after passing through the modulator. The role of the optical fiber is first to transmit the light beam and second to act as an optical modulator.

[0036] In this embodiment, the spring detection device 8 is a magnetic induction switch. The spring detection device 8 is mounted on the feeding seat 4 through the second mounting seat. The magnetic induction switch includes a magnet and an induction coil arranged opposite to the magnet. The output end of the induction coil is connected to the input end of the switch circuit, and the output end of the switch circuit is connected in series to the input end of the power supply. The second mounting seat is provided with a mounting hole for mounting the magnetic induction switch, and a clamping groove is provided on the mounting hole. The clamping groove communicates with the mounting hole. Therefore, the magnetic induction switch can be mounted on the mounting hole and the angle of the magnetic induction switch can be adjusted arbitrarily. After adjustment, it is locked with screws.

[0037] In this embodiment, the stainless steel sheet detection device 9 is a fiber optic sensor or a magnetic induction switch.

[0038] In this embodiment, as Figure 8 shown, the button and spring pressing detection device 10 includes a pressing plate 101, a pressing cylinder 102, and a pressure sensor. The pressure sensor is connected to the pressing cylinder 102. The pressing cylinder 102 can drive the pressing plate 101 to press the button 163 and the spring 161 of the automotive seat conduit 16 back and forth, and judge whether the pressure of the button 163 and the spring 161 of the automotive seat conduit 16 is sufficient through the pressure sensor.

[0039] In this embodiment, as Figure 6 andFigure 7 As shown, the material moving device 11 includes a left - right transverse movement driving device, a lifting driving device, and a pushing claw. The lifting driving device is installed on the left - right transverse movement driving device. The left - right transverse movement driving device can drive the lifting driving device to move up and down. The pushing claw is installed on the lifting driving device, and the lifting driving device can drive the pushing claw to move up and down.

[0040] In this embodiment, the left - right transverse movement driving device includes a mounting frame 1111, a first guide rail 1112, a driving cylinder 1113, and a transverse movement plate 1114. The transverse movement plate 1114 is installed on the mounting frame 1111 through the first guide rail 1112, and the driving cylinder 1113 can drive the transverse movement plate 1114 to move left and right along the first guide rail 1112.

[0041] In this embodiment, the lifting driving device includes a second guide rail 1121, a lifting plate 1122, and a first lifting cylinder 1123. The pushing claw is installed on the lifting plate 1122. The lifting plate 1122 is installed on the second guide rail 1121, and the second guide rail 1121 is installed on the transverse movement plate 1114. The first lifting cylinder 1123 can drive the pushing claw to move up and down.

[0042] In this embodiment, there are four groups of pushing claws. Each group of pushing claws corresponds to the automotive seat ducts in the following processes. The following processes are: a spring detection device 8, a stainless - steel sheet detection device 9, a defective product discharging device 12, and a dotting device 13. The pushing claw includes a first pushing claw part 1131 and a second pushing claw part 1133. There is a clearance part 1132 between the first pushing claw part 1131 and the second pushing claw part 1133 for accommodating the automotive seat duct 16. In this way, when the automotive seat duct 16 in the above - mentioned process has completed the corresponding process, the pushing claw can simultaneously move the automotive seat duct 16 in the previous process to the next process for detection. For example, the automotive seat duct 16 on the spring detection device 8 will come to the stainless - steel sheet detection device 9 under the push of the pushing claw.

[0043] Such as Figure 12 and Figure 13As shown, a flexible baffle 1134 is provided on the second pusher claw part 1133 of the pusher claw at the rightmost end. Then, a baffle 141 is provided at the leftmost end of the discharge conveyor belt 14. When the pusher claw pushes the vehicle seat conduit 16 onto the discharge conveyor belt 14, first, the vehicle seat conduit 16 is blocked by the baffle 141, causing the upper end of the vehicle seat conduit 16 to tilt to the right and lean against the flexible baffle 1134. Finally, the flexible baffle 1134 moves to the right along with the pusher claw, thus laying the vehicle seat conduit 16 down on the discharge conveyor belt 14. By providing the baffle 141 and the flexible baffle 1134, when the vehicle seat conduit 16 is pushed from the feeding guide rail 41 onto the discharge conveyor belt 14 by the pusher claw, it can ensure that the tilting direction of the vehicle seat conduit 16 remains consistent, preventing the vehicle seat conduit 16 from tilting in various directions when it is tilted, thus affecting the transportation of the vehicle seat conduit 16.

[0044] In this embodiment, as Figure 11 shown, the dotting device 13 includes a counter, a mounting base 131, a second lifting cylinder 132, a dotting pen 133, and a pen clamping assembly 134. The dotting pen 133 is clamped by the pen clamping assembly 134. The pen clamping assembly 134 is mounted on the telescopic rod of the second lifting cylinder 132. The second lifting cylinder 132 is mounted on the mounting base 131. The mounting base 131 is mounted on the workbench 3. The counter can record each vehicle seat conduit 16 marked by the dotting pen 133.

[0045] In this embodiment, the pen clamping assembly 134 includes a clamping seat 1341, a dotting cylinder 1342, and a fixing seat 1343. The clamping seat 1341 is rotatably mounted on the dotting cylinder 1342. The dotting cylinder 1342 is mounted on the fixing seat 1343. The dotting cylinder 1342 can drive the dotting pen 133 to move back and forth.

[0046] As Figure 10 shown, the defective product discharging device 12 is respectively mounted between the feeding seats 4. Each group of defective product discharging devices 12 includes a discharging plate 121, a discharging cylinder 122, and a discharging seat 123. The upper side edge of the discharging plate 121 is flush with the feeding guide rail 41. The discharging plate 121 is mounted on the discharging cylinder 122. The discharging cylinder 122 is mounted on the discharging seat 123. At this time, the lower side of the head of the vehicle seat conduit 16 just hangs on the upper side surface of the discharging plate 121. When it is determined that the vehicle seat conduit 16 is a defective product, the discharging cylinder 122 drives the discharging plate 121 to move forward and backward respectively, so that the discharging plate 121 leaves from the bottom of the vehicle seat conduit 16, and thus the vehicle seat conduit 16 falls into the corresponding blanking hole 31 on the workbench 3 to collect the defective products.

[0047] The working principle of the present invention is:

[0048] When the present invention works, first, the automobile seat conduit 16 is placed on the feeding conveyor assembly 5, and the feeding conveyor assembly 5 conveys the automobile seat conduit 16 to the lower part of the feeding manipulator 6. At the same time, the feeding positioning detection device 7 detects whether there is an automobile seat conduit 16 under the feeding manipulator 6. Then, the feeding manipulator 6 pushes the automobile seat conduit 16 to the right and moves it along the feeding guide rail 41 to the spring detection device 8. The spring detection device 8 detects whether there is a mounting spring 161 in the automobile seat conduit 16. After the detection, the material moving device 11 pushes the automobile seat conduit 16 to the right and moves it along the feeding guide rail 41 to the position between the stainless steel sheet detection device 9 and the button and spring pressing detection device 10. Then, the stainless steel sheet detection device 9 starts to detect whether there is a mounting stainless steel sheet 162 in the automobile seat conduit 16. At the same time, the button and spring pressing detection device 10 performs a pressing detection on the button 163 and the spring 161 of the automobile seat conduit 16. After the detection, the material moving device 11 continues to push the automobile seat conduit 16 to the right and moves it along the feeding guide rail 41 to the defective product discharging device 12. If the defective product discharging device 12 receives that the material moving device is a defective product, the defective product discharging device 12 discharges the defective product. If it is a good product, the material moving device 11 continues to push the automobile seat conduit 16 to the right and moves it along the feeding guide rail 41 to the dotting device 13. The dotting device 13 uses a dotting pen 133 to make a dotting mark on the automobile seat conduit 16 and perform a quantity statistics. Finally, the material moving device 11 pushes the dotted automobile seat conduit 16 onto the discharging conveyor belt 14, and the discharging conveyor belt 14 conveys the automobile seat conduit 16 into the good product collection box 15, thus completing the entire processes of detecting, dotting and counting of the automobile seat conduit 16. In summary, the present invention can realize the automatic detection, automatic dotting and automatic quantity statistics of whether there are a spring 161 and a stainless steel sheet 162 in the automobile seat conduit 16, as well as the pressing of the button 163 and the spring 161 of the automobile seat conduit, thereby greatly reducing the labor intensity of workers and improving the detection efficiency.

[0049] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
