[0001] The present application relates to the technical field of automobile production equipment, and in particular to an incoming material detection device and a detection control method for an automobile production line. Background Art

[0002] The automobile production line is an assembly line for producing automobiles. Its operation line processes include welding, stamping, painting, powertrain, etc., which enables automobile manufacturers to improve the level of automation. Auto parts are various units that make up the whole car and a product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of automobiles is also increasing. The market for auto parts has become larger and larger. In recent years, auto parts manufacturers have also been developing rapidly.

[0003] A car is made up of many parts and components, which are then assembled and produced on a production line. During the assembly of auto parts, it is necessary to inspect the incoming auto parts. For current incoming material inspection devices, most of them use fixed inspection equipment at a certain position of the production line to inspect and process the incoming auto parts, which is too passive. When there are a large number of auto parts on the production line, it is easy to cause congestion of auto parts on the production line, and the inspection efficiency is not ideal.

[0010] Preferably, the transfer inspection component includes a small synchronous wheel, two groups of the small synchronous wheels are connected to the large synchronous wheel through a synchronous belt, and a limit slot is provided on one side of the small synchronous wheel, and a limit clamping head engaged with the limit slot is provided on the other side of the two groups of small synchronous wheels, and a first electric push rod is fixedly connected to the side of the limit clamping head away from the limit slot, and an extension screw rod is fixedly connected to the outer wall of the two groups of the first electric push rods;

[0011] The outer wall of the extended screw rod is threadedly connected to a threaded barrel, the outer walls of the two groups of threaded barrels are fixedly connected to a bracket used in conjunction with the feeding rack, and a detector is embedded on the top of the bracket, and industrial cameras used in conjunction with the detector are fixedly connected on both sides of the bracket.

[0012] Preferably, the surface wall of the long rod is rotatably connected from left to right in sequence with a rotating sleeve fixedly matched with the feeding rack, and the rod of the cleaning rod and the conveying roller of the loading rack are distributed in a staggered state, and the two groups of cleaning rods use thin rod-type rubber bristles.

[0013] Preferably, the bottom ends of the two groups of delivery pipes are integrally formed with external threads, and the top end of the dust collecting bag is provided with an internal thread groove that matches the external thread.

[0014] Preferably, a moving wheel is fixedly connected to the bottom of the bracket, guide rails are fixedly connected to both sides of the feeding rack, and the inner cavity of the guide rails is slidably connected to a guide rail block fixedly matched with the bracket.

[0015] Preferably, both sides of the loading and unloading places of the feeding rack are fixedly connected with incoming material signal sensors, and the bottom of the loading rack is fixedly connected with a collecting box.

[0016] Preferably, both sides of the inner cavity of the feed rack are fixedly connected with push rod cylinders, and the piston rod of the push rod cylinder is fixedly connected with a baffle plate that is staggered with the conveying roller of the feed rack.

[0017] A detection control method for an incoming material detection device of an automobile production line, used for any of the above-mentioned incoming material detection devices of an automobile production line, comprises the following steps:

[0018] Step 1: first place the auto parts on the loading rack, and seal and protect the auto parts on the loading rack with a sealing cover, control the double-headed motor and the push rod cylinder located at the loading position of the feeding rack to open in advance, and the push rod cylinder at this position drives the blocking plate to move up to block the auto parts on the loading rack, and at the same time, an output shaft of the double-headed motor drives the large synchronous wheel to rotate, and the large synchronous wheel drives the worm at the end of the long rod to rotate synchronously, and the worm drives the cleaning rods on the two sets of worm wheels to rotate accordingly, and the two sets of cleaning rods in a rotating state clean the dust and impurities on the surface of the auto parts on the loading rack. During the cleaning of the auto parts, the light dust particles that fall off from the auto parts float in the sealing cover, and the large particles of impurities that fall off directly pass through the conveying roller of the loading rack and fall into the collection box, and then the staff will clean the large particles of impurities in the collection box uniformly;

[0019] The second step is to drive the two sets of dust exhaust fans to rotate while the two sets of cleaning rods rotate, and control the two sets of solenoid valves to open. Since the sealing cover seals and protects the auto parts on the loading rack, the two sets of rotating dust exhaust fans discharge the light dust particles that float after the auto parts in the sealing cover are cleaned into the two sets of dust conveying pipes. The light dust particles are then discharged into the two sets of dust collecting bags through the two sets of conveying pipes after the channels are opened. Then, the push rod cylinder located at the loading position of the feeding rack is controlled to be closed and the baffle plate is driven to move down and reset. After the loading rack transfers the cleaned auto parts to the feeding rack, the staff places the next set of auto parts on the loading rack and performs cleaning and dust removal. At the same time, the push rod cylinder located at the loading position of the feeding rack is controlled to be opened again and the baffle plate is driven to move up to perform baffle treatment on the next set of auto parts on the loading rack, and the next set of auto parts is cleaned, and so on, so that multiple sets of cleaned auto parts are orderly transferred to the feeding rack.

[0020] Step 3. When the auto parts to be cleaned are transmitted to the feeding rack in an orderly manner, the incoming signal sensor at the feeding position of the feeding rack senses the incoming auto parts in turn, first controls the double-headed motor to pause, then controls the two groups of first electric push rods to start and drive the two groups of limit clamps to correspondingly snap into the limit clamping grooves on the two groups of small synchronous wheels, and then controls the double-headed motor to continue to start and drive the large synchronous wheel to rotate forward. At the same time, the large synchronous wheel drives the two groups of small synchronous wheels to rotate synchronously through the synchronous belt, and the two groups of small synchronous wheels drive the two groups of extended lead screws to rotate forward through the two groups of limit clamps and the first electric push rod connected as one. The two groups of guide rails and guide rail blocks provide sliding limit compensation for the two groups of brackets, and the two groups of extended lead screws drive the two groups of brackets on the threaded barrels to move forward. While moving, the bracket also drives the two sets of moving wheels to move forward, and the bracket then drives the detector and the front and rear sets of industrial cameras to move forward along the feeding rack until the detector and the front and rear sets of industrial cameras move to the predetermined position on the feeding rack. Then the detector and the front and rear sets of industrial cameras will actively take pictures and detect the processed auto parts on the feeding rack. Similarly, active photo detection operations can also be performed on auto parts at any position of the feeding rack, and the push rod cylinder located at the unloading position of the feeding rack is controlled to open and drive the baffle plate to move up. The moved up baffle plate will block the auto parts that have undergone active photo detection operations at the unloading position of the feeding rack until all the auto parts that have been orderly transmitted on the feeding rack have been photographed and detected.

[0021] The beneficial effect of the present application is that before the incoming automobile parts are inspected, the double-headed motor of the processing component first provides a unified driving source, and the large synchronous wheel and the long rod drive the two groups of cleaning sticks to rotate through the two groups of worm gears on the worm to clean the fed automobile parts. At the same time, the two groups of dust exhaust fans of the dust collection component sequentially supply the dust to the two groups of dust collection bags through the two groups of dust conveying pipes, the conveying pipes and the solenoid valves, and the light dust particles falling on the automobile parts in the cleaning state are removed and collected, so as to achieve the pre-treatment effect of automobile parts, provide convenience for the subsequent automobile parts inspection, and prevent automobile parts from being damaged. Too many impurities on the surface affect the detection accuracy. During the inspection of incoming auto parts, the two groups of first electric push rods of the transfer inspection component adjust the stroke position of the two groups of limit clamps, and drive the two groups of extended lead screws on the small synchronous wheels to rotate through the two groups of limit clamp slots. Then, the two groups of threaded barrels drive the detector on the bracket and the two groups of industrial cameras to adjust the displacement back and forth, and actively take pictures and detect the incoming auto parts to prevent congestion caused by too many auto parts. At the same time, it also avoids the phenomenon of missed detection of auto parts and improves the detection efficiency of auto parts.

[0048] The feeding rack 3 is provided with a processing component 4 and a dust collecting component 5 used in conjunction with the sealing cover 2, respectively, to pre-treat the surface of the loaded automobile parts, improve the cleanliness of the automobile parts, and prevent dust from adhering to the surface of the automobile parts, which may affect the subsequent inspection work;

[0049] The feeding rack 3 is provided with a transfer inspection component 6 for actively taking photos and inspecting the incoming automobile parts.

[0050] like Figures 6 to 10 As shown, the current incoming material detection device is mostly a fixed detection device at a certain position of the production line to detect and process the incoming auto parts, which is too passive and cannot actively detect the auto parts based on pre-processing, which can easily cause congestion of auto parts on the production line and low detection efficiency. The processing component 4 includes a double-headed motor 41, which is fixed to one side of the bottom of the feeding rack 3 and is provided with a unified driving source by the double-headed motor 41;

[0054] The bottom ends of the two groups of conveying pipes 53 are integrally formed with external threads 12, and the top end of the dust bag 55 is provided with an internal thread groove 13 threadably matched with the external threads 12, so that the staff can quickly disassemble and clean the dust bag 55.

Guide bars 15 are fixedly connected to both sides of the feeding rack 3, and the inner cavity of the guide bar 15 is slidably connected with a guide block 16 fixedly matched with the bracket 67, so as to realize sliding limit compensation on both sides of the bracket 67 to prevent shaking displacement during the displacement of the bracket 67.

[0058] like Fig.11 and Fig.12 As shown, after the incoming auto parts on the production line are inspected, most of them are manually sorted and unloaded by humans for defective and doubtful products. It is not possible to accurately and quickly sort and unload each auto part according to the inspection results, which is time-consuming and labor-intensive. Manual sorting may also cause sorting errors and omissions, and rework is still required, which is not worth the cost. The unloading place of the feeding rack 3 is connected with a fixed rack 7, and the surrounding of the fixed rack 7 is also fixedly connected with incoming signal sensors 17. The incoming signal sensors 17 at different unloading places sense the incoming auto parts unloaded from the feeding rack 3.

While sensing the incoming materials of the automobile parts unloaded by the feeding frame 3, the corresponding unloading and conveying processing of the automobile parts with different detection results is also carried out, so as to achieve accurate sorting effect, replace manual sorting operation, and save time and labor;

[0060] A classification component 11 for use with the unloading rack 8, the defective rack 9 and the transfer rack 10 is provided on the fixed frame 7, and the classification component 11 includes an annular slide groove 111, and the annular slide groove 111 is opened at the center of the fixed frame 7, and a second electric push rod 112 is embedded in the other output shaft of the double-headed motor 41, and the piston rod of the second electric push rod 112 is fixedly connected to the driving bevel gear 113, and the second electric push rod 112 adjusts and compensates the stroke position of the driving bevel gear 113;

[0062] An angle sensor 117 is embedded on one side of the bogie 115, and the angle sensor 117 detects the rotation angle of the bogie 115 each time, so that the bogie 115 can be accurately turned to the loading position of the unloading rack 8, the defective rack 9 and the transfer rack 10. A servo motor used in conjunction with a conveyor roller is embedded on the other side of the bogie 115. According to the loading requirements of the unloading rack 8, the defective rack 9 and the transfer rack 10, the auto parts with different test results on the bogie 115 can be controlled to be forwarded or reversely transported, thereby meeting the corresponding unloading requirements of auto parts with different test results.

[0063] A detection control method for an incoming material detection device of an automobile production line, used for any of the above-mentioned incoming material detection devices of an automobile production line, comprises the following steps:

[0064] Step 1, first place the automobile parts on the loading rack 1, and the sealing cover 2 seals and protects the automobile parts on the loading rack 1, and controls the double-headed motor 41 and the push rod cylinder 18 located at the loading position of the feeding rack 3 to open in advance, and the push rod cylinder 18 at this position drives the blocking plate 19 to move up to block the automobile parts on the loading rack 1, and at the same time, an output shaft of the double-headed motor 41 drives the large synchronous wheel 42 to rotate, and the large synchronous wheel 42 drives the worm 44 at the end of the long rod 43 to rotate synchronously, and the worm 44 drives the cleaning rods 46 on the two groups of worm wheels 45 to rotate accordingly, and the two groups of cleaning rods 46 in a rotating state clean the dust and impurities on the surface of the automobile parts on the loading rack 1. During the cleaning of the automobile parts, the light dust particles that fall off from the automobile parts float in the sealing cover 2, and the large particles of impurities that fall off directly pass through the conveying roller of the loading rack 1 and fall into the collection box, and then the large particles of impurities in the collection box are cleaned uniformly by the staff;

[0065] Step 2: When the two cleaning rods 46 rotate, the two dust exhaust fans 51 are also driven to rotate, and the two solenoid valves 54 are controlled to open. Since the sealing cover 2 seals and protects the auto parts on the loading rack 1, the two rotating dust exhaust fans 51 discharge the light dust particles that float after the auto parts in the sealing cover 2 are cleaned into the two dust conveying pipes 52. The light dust particles are then discharged into the two dust collecting bags 55 through the two conveying pipes 53 after the channels are opened. Then, the push rod cylinder 18 located at the loading position of the feeding rack 3 is controlled to be closed and The baffle plate 19 is driven to move downward and reset, and then the loading rack 1 transfers the cleaned auto parts to the feeding rack 3. The staff then places the next group of auto parts on the loading rack 1 and performs cleaning and dust removal. At the same time, the push rod cylinder 18 located at the loading position of the feeding rack 3 is controlled to open again and drive the baffle plate 19 to move upward to perform material blocking on the next group of auto parts on the loading rack 1, and clean the next group of auto parts, and so on, so that multiple groups of cleaned auto parts are orderly transferred to the feeding rack 3;

[0066] Step 3, when the automobile parts to be cleaned are orderly transmitted to the feeding rack 3, the incoming signal sensor 17 at the feeding position of the feeding rack 3 senses the incoming automobile parts in turn, first controls the double-headed motor 41 to pause, then controls the two groups of first electric push rods 64 to start and drive the two groups of limit clamps 63 to correspondingly snap into the limit clamping grooves 62 on the two groups of small synchronous wheels 61, and then controls the double-headed motor 41 to continue to start and drive the large synchronous wheel 42 to rotate forward. At the same time, the large synchronous wheel 42 drives the two groups of small synchronous wheels 61 to rotate synchronously through the synchronous belt, and the two groups of small synchronous wheels 61 drive the two groups of extended lead screws 65 to rotate forward accordingly through the two groups of limit clamps 63 and the first electric push rods 64 connected as one. The two groups of guide rails 15 and the guide rail blocks 16 provide sliding limit compensation for the two groups of brackets 67, and the two groups of extended lead screws 65 drive the two groups of threaded cylinders 66 on When the bracket 67 moves forward, the bracket 67 also drives the two groups of moving wheels 14 to move forward accordingly.

Then, the detector 68 and the front and rear two groups of industrial cameras 69 actively take photos and detect the processed automobile parts on the feeding rack 3. Similarly, active photo detection operations can also be performed on automobile parts at any position of the feeding rack 3, and the push rod cylinder 18 located at the unloading position of the feeding rack 3 is controlled to open and drive the baffle plate 19 to move upward. The baffle plate 19 after moving upward performs a material blocking process on the automobile parts that have been actively photographed and detected at the unloading position of the feeding rack 3 until all the automobile parts orderly transmitted on the feeding rack 3 have been photographed and detected;

[0067] Step 4, after the detector 68 and the front and rear two groups of industrial cameras 69 have finished actively photographing and inspecting all the auto parts on the feeding rack 3, first control the double-headed motor 41 to pause, control the two groups of first electric push rods 64 to close and drive the two groups of limit clamps 63 to correspondingly disengage the limit clamping slots 62 on the two groups of small synchronous wheels 61, and then control the push rod cylinder 18 located at the unloading position of the feeding rack 3 to close and drive the baffle plate 19 to move down and reset, so that the feeding rack 3 can transport the auto parts after the photographing inspection to the surface of the bogie 115 on the fixed frame 7 in an orderly manner, and the incoming signal sensor 17 on the fixed frame 7 senses the auto parts after the photographing inspection, and controls the second electric push rod 112 to open and drive the driving bevel gear 113 to move to the meshing part of the driven bevel gear 114, and then control the double-headed motor 41 to open in the forward or reverse direction, and the double-headed motor 41 passes through the second electric push rod 1 The driving bevel gear 113 on 12 drives the driven bevel gear 114 to rotate forward or reverse accordingly, and the annular convex strip 116 and the annular slide groove 111 provide rotation support compensation for the bogie 115, then the driven bevel gear 114 drives the bogie 115 to rotate forward or reverse on the fixed frame 7, and the angle sensor 117 detects the current rotation angle of the bogie 115, and according to the detection results of the current auto parts by the detector 68 and the front and rear two groups of industrial cameras 69, the bogie 115 in place will transport the auto parts to the unloading rack 8, the defective rack 9 or the transfer rack 10 for unloading of qualified auto parts, unloading of defective auto parts or unprocessed auto parts, and so on, and the auto parts with different detection results are unloaded accordingly, and finally the staff will carry out corresponding processing on the defective auto parts and unprocessed auto parts.

[0068] It should be noted that the specific models and specifications of the double-headed motor 41, the first electric push rod 64, the second electric push rod 112 and the detector 68 need to be selected and determined according to the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
