Description

Technical Field

[0001] The present invention relates to the field of sheet metal parts acceptance, and in particular to an automobile sheet metal parts acceptance device. Background Art

[0002] The acceptance inspection of automotive sheet metal parts primarily focuses on appearance and dimensions. Appearance inspection includes surface flatness, scratches, dents, and deformation, and requires a uniform paint finish with no color variations. Dimensional measurements require specialized tools such as calipers and measuring tools to ensure the sheet metal parts conform to the design drawings and assembly requirements, and that tolerances meet standards. Welding joints are also inspected for strength, porosity, and crack-free welds. Qualified sheet metal parts ensure the vehicle's aesthetically pleasing appearance and structural strength, meeting subsequent assembly and operational requirements.

[0003] Dust on sheet metal parts will affect the acceptance inspection. It will cause misjudgment, affect accuracy, cover up defects, and even damage detection equipment and probes in many aspects such as appearance, size, morphology, surface quality and non-destructive testing. Dust will cover up some minor defects on the surface of sheet metal parts, such as scratches, pits, small cracks, etc. During the acceptance process, if there is a lot of dust on the surface of the sheet metal parts, the acceptance personnel may not be able to accurately observe these defects, thereby affecting the judgment of the appearance quality of the sheet metal parts. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automobile sheet metal parts acceptance device.

[0005] The present invention provides an automobile sheet metal parts acceptance device, comprising a base and:

[0006] An acceptance channel is fixed to the top of the base;

[0007] An installation chamber is fixed on the top of the acceptance channel;

[0008] A detector, installed inside the acceptance channel, for inspecting sheet metal parts using laser;

[0009] A conveying assembly, installed inside the installation bin, for conveying the sheet metal parts into the acceptance channel;

[0010] A partition assembly is installed inside the acceptance channel and is used to separate the interior of the acceptance channel into a moving space and a detection space;

[0011] An airflow dust removal component is installed inside the detection space and is used to transport airflow from the inside of the detection space to the moving space to prevent dust from entering the detection space along the moving space;

[0012] The conveying component transports the sheet metal parts that need to be inspected to the interior of the acceptance channel. When transported to the interior of the moving space, the partition component separates the moving space and the inspection space. As the sheet metal parts continue to be transported, the partition component opens, so that the moving space and the inspection space are connected. At this time, the airflow dust removal component is started synchronously. After the airflow dust removal component is started, it drives the airflow to flow along the direction of the inspection space and the moving space, which helps to avoid dust from entering the sheet metal parts during the process of the sheet metal parts entering the acceptance space, causing dust to adhere to the sheet metal parts and affect the inspection results. Similarly, when the sheet metal parts are transported and discharged, the detector can inspect and accept the surface of the sheet metal parts.

[0013] Preferably, the transmission assembly comprises:

[0014] Two rotating rollers are symmetrically mounted on both ends of the base;

[0015] a motor, fixed to a side wall of the base, the motor being used to drive one of the rotating rollers to rotate;

[0016] A conveyor belt, the transmission sleeve of which is arranged on the outer rings of the two rotating rollers;

[0017] After the motor is started, the output shaft drives the rotating roller connected to it to rotate. After the rotating roller rotates, it drives the conveyor belt connected to it to transmit, so that the sheet metal parts are transported by the conveyor belt to move into the detection space.

[0018] Preferably, the partition assembly comprises:

[0019] Two cylinders are symmetrically fixed on the top of the installation chamber;

[0020] A lifting platform is slidably mounted inside the installation chamber, and the two cylinders drive the lifting platform to move vertically through telescopic rods respectively;

[0021] Two groups of baffles, with multiple baffles forming one group. The baffles in the same group are slidably inserted into the clearance opening opened on the same lifting platform, and the tops of all the baffles are fixed with limit blocks;

[0022] After the cylinder is started, the lifting platform is driven downward by the telescopic rod. The lifting platform drives the baffle downward by friction. When the bottom of the baffle is blocked, the baffle will move upward relative to the lifting platform along the make way opening to make way. This helps to avoid the situation where the other baffles cannot move downward synchronously when one of the baffles is blocked, thereby facilitating sufficient isolation of the detection space and the moving space.

[0023] When the lifting platform moves upward, the lifting platform pushes the limit block to move upward, and the limit block drives the baffle to move upward, thereby driving all the baffles to move upward and reset.

[0024] Preferably, the partition assembly further comprises:

[0025] A plurality of cleaning brushes are respectively fixed to the bottom of each baffle;

[0026] When the baffle moves downward, the height of the baffle can be controlled so that the cleaning brush contacts the surface of the sheet metal, thereby cleaning the surface of the sheet metal. The cleaning brush is a soft-bristled brush, which can cause the dust attached to the surface of the sheet metal to float up, thereby removing the dust attached to the surface of the sheet metal, which is helpful to reduce the interference of dust on acceptance.

[0027] Preferably, the airflow ash removal component includes:

[0028] Two first communication channels are symmetrically fixed at the center of the acceptance channel;

[0029] Two sets of exhaust ports are respectively installed on the side walls of the first communicating channel in a linear array along the trajectory of the first communicating channel and facing the direction of the moving space;

[0030] a fan, fixed inside the installation compartment and connected to the two first communication channels through connecting pipes;

[0031] After the fan is started, it drives the air flow to the interior of the first connecting channel, and then is discharged from the exhaust port on the side wall of the first connecting channel. The air flow discharged from the exhaust port flows in the direction of the moving space. Therefore, under the action of the flow of air, on the one hand, it drives the internal air flow to be discharged, and on the other hand, it helps to prevent external dust from entering the interior of the acceptance space with the movement of the sheet metal, thereby helping to reduce the interference of dust on the acceptance.

[0032] Preferably, the airflow ash removal component further includes:

[0033] a collection box fixed inside the installation compartment, wherein the top of the collection box is connected to the connecting pipe, and the bottom of the collection box is connected to the first communication channel;

[0034] A filter element is fixed inside the collection box;

[0035] The airflow driven by the fan is filtered by the filter element when passing through the interior of the collection box. The filter element can filter the airflow entering the detection space to prevent dust from entering the detection space with the airflow, which is beneficial to reduce the interference of dust on acceptance.

[0036] Preferably, the airflow ash removal component further includes:

[0037] Two negative pressure pumps are symmetrically fixed on the top of the acceptance channel;

[0038] Two second communication channels are respectively fixed at two ends of the acceptance channel, and the input end of the negative pressure pump is connected to the second communication channels;

[0039] a plurality of openings, respectively formed on the side walls of the two second communicating channels;

[0040] The negative pressure pump can connect to the second connecting channel to extract the gas inside the second connecting channel, so that the inside of the second connecting channel is in a negative pressure state. When the airflow flows toward the moving space, under the guidance of the negative pressure, the airflow will flow toward the position of the opening, thereby guiding the flow of the airflow so that the airflow flows along the path of the detection space and the moving space. By controlling the negative pressure pump, the amount of guidance of the airflow can be controlled.

[0041] Preferably, the airflow ash removal component further includes:

[0042] an air inlet pipe, fixed between an input end connected to the negative pressure pump and the second communicating channel;

[0043] an exhaust pipe fixedly connected between the output end of the negative pressure pump and the second communicating channel;

[0044] A first connecting end pipe is fixed on the side wall connected to the air inlet pipe;

[0045] A second connecting end pipe is fixed on the side wall connected to the exhaust pipe;

[0046] Four control valves, respectively fixed to the ends of the air inlet pipe and the exhaust pipe, the interior of the first connecting end pipe, and the interior of the second connecting end pipe;

[0047] When only the control valve inside the air inlet pipe and the second connecting end pipe is opened, the interior of the second connecting channel is in a negative pressure state, which can guide the airflow. When only the control valve inside the exhaust pipe and the first connecting end pipe is opened, the interior of the second connecting channel is in a high pressure state, which can discharge the airflow through the opening. Therefore, when the high-pressure airflow is discharged, the surface of the sheet metal can be impacted by the high-pressure airflow to form an air curtain, which can clean the attached dust on the one hand and further prevent the entry of dust under the action of the air curtain on the other hand.

[0048] Preferably, the partition assembly further comprises:

[0049] A plurality of arc-shaped frames are respectively fixed to the bottom of each of the baffles;

[0050] A plurality of mounting slots are respectively provided through the middle of each of the arc-shaped frames;

[0051] A plurality of micro drive fans are respectively installed inside the installation slots;

[0052] The setting of the arc frame pushes the bottom edge of the arc frame when the sheet metal moves, so that it will not directly impact the baffle, but has the force to push the arc frame upward, which is beneficial to avoid damage to the baffle when the sheet metal moves. After the micro-drive fan is started, it can drive the airflow through the inside of the installation slot, thereby forming an airflow guidance path, so that the airflow passes through each position evenly to guide the dust out, so as to reduce the entry of dust and thus reduce the interference of dust on acceptance.

[0053] Preferably, the partition assembly further comprises:

[0054] a distance sensor, mounted on a side wall of one of the baffles;

[0055] The distance sensor can detect the distance between the sheet metal and the baffle, so that when the arc frame cannot move upward to make way through its own guidance, the baffle can be driven upward to make way through the cylinder.

[0056] Compared with the prior art, the present invention has the following beneficial effects:

[0057] The present invention, through the provision of a separation component and an airflow dust removal component, is conducive to preventing dust from entering the sheet metal part simultaneously when the sheet metal part enters the acceptance space, causing dust to adhere to the sheet metal part and affect the detection results.

[0065] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0066] like Figures 1 to 6 The automobile sheet metal parts acceptance device shown includes a base 1 and also includes:

[0067] The inspection channel 101 is fixed on the top of the base 1;

[0068] The installation chamber 102 is fixed on the top of the acceptance channel 101;

[0069] The detector 103 is installed inside the acceptance channel 101 and is used to detect the sheet metal parts using laser;

[0070] A conveying assembly is installed inside the installation chamber 102 and is used to convey the sheet metal parts to the interior of the acceptance channel 101;

[0071] A partition assembly is installed inside the acceptance channel 101 and is used to separate the interior of the acceptance channel 101 into a moving space and a detection space;

[0072] An airflow dust removal component is installed inside the detection space and is used to transport airflow from the inside of the detection space to the moving space to prevent dust from entering the detection space along the moving space;

[0073] Dust on sheet metal parts can affect acceptance, causing misjudgments, affecting accuracy, masking defects, and even damaging inspection equipment and probes in terms of appearance, dimensional shape, surface quality, and non-destructive testing. Dust can mask minor surface defects such as scratches, pits, and small cracks. During the acceptance process, if there is a large amount of dust on the surface of the sheet metal part, the inspector may not be able to accurately observe these defects, thus affecting their judgment of the appearance quality of the sheet metal part.

[0074] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the conveying component transports the sheet metal parts that need to be inspected to the interior of the acceptance channel 101. When transported to the interior of the moving space, the partition component separates the moving space and the inspection space. As the sheet metal parts continue to be transported, the partition component opens, so that the moving space and the inspection space are connected. At this time, the airflow dust removal component is started synchronously. After the airflow dust removal component is started, the airflow drives the airflow to flow along the direction of the inspection space and the moving space, which is conducive to avoiding the simultaneous entry of dust during the process of the sheet metal parts entering the acceptance space, causing dust to adhere to the sheet metal parts and affect the inspection results. Similarly, when the sheet metal parts are transported and discharged, the detector 103 can inspect and accept the surface of the sheet metal parts.

[0075] As an optional embodiment, the transmission component includes:

[0076] Two rotating rollers 202 are symmetrically mounted on both ends of the base 1;

[0077] The motor 201 is fixed to the side wall of the base 1 and is used to drive one of the rotating rollers 202 to rotate;

[0078] The conveyor belt 2 is provided with a transmission sleeve on the outer rings of the two rotating rollers 202;

[0079] After the motor 201 is started, the output shaft drives the rotating roller 202 connected thereto to rotate. After the rotating roller 202 rotates, the conveyor belt 2 connected thereto is driven to transmit, thereby transporting the sheet metal parts through the transmission of the conveyor belt 2 to drive the sheet metal parts to move into the interior of the detection space.

[0080] As an optional embodiment, the partition assembly includes:

[0081] Two cylinders 3 are symmetrically fixed on the top of the installation chamber 102;

[0082] The lifting platform 301 is slidably mounted inside the installation chamber 102, and the two cylinders 3 respectively drive the lifting platform 301 to move vertically through the telescopic rods;

[0083] Two groups of baffles 303, with multiple baffles 303 forming one group, are slidably inserted into the opening 302 provided on the same lifting platform 301, and the tops of all baffles 303 are fixed with limit blocks 304;

[0084] After the cylinder 3 is started, the lifting platform 301 is driven downward by the telescopic rod. The lifting platform 301 drives the baffle 303 downward by friction. When the bottom of the baffle 303 is blocked, the baffle 303 moves upward relative to the lifting platform 301 along the yielding opening 302 to make way. This helps to avoid the situation where the other baffles 303 cannot move downward synchronously when one of the baffles 303 is blocked, thereby facilitating sufficient isolation of the detection space and the movement space.

[0085] When the lifting platform 301 moves upward, the lifting platform 301 pushes the limiting block 304 to move upward, and the limiting block 304 drives the baffle 303 to move upward, thereby driving all the baffles 303 to move upward and reset.

[0086] As an optional embodiment, the partition assembly further includes:

[0087] A plurality of cleaning brushes 4 are fixed to the bottom of each baffle 303;

[0088] When the baffle 303 moves downward, the height of the baffle 303 can be controlled so that the cleaning brush 4 contacts the surface of the sheet metal, thereby cleaning the surface of the sheet metal through the cleaning brush 4. The cleaning brush 4 uses a soft-bristle brush, which can cause the dust attached to the surface of the sheet metal to float up, thereby removing the dust attached to the surface of the sheet metal, which is beneficial to reduce the interference of dust on acceptance.

[0089] As an optional embodiment, the airflow dust removal component includes:

[0090] Two first communication channels 5 are symmetrically fixed at the center of the acceptance channel 101;

[0091] Two sets of exhaust ports 501 are respectively installed on the side walls of the first communicating channel 5 in a linear array along the trajectory of the first communicating channel 5 and facing the direction of the moving space;

[0092] The fan 502 is fixed inside the installation chamber 102 and is connected to the two first communication channels 5 through the connecting pipe 503;

[0093] After the fan 502 is started, it drives the air flow to the interior of the first connecting channel 5, and then is discharged from the exhaust port 501 on the side wall of the first connecting channel 5. The air flow discharged from the exhaust port 501 flows in the direction of the moving space. Under the action of the flow of the air flow, on the one hand, it drives the internal air flow to be discharged. On the other hand, it helps to prevent external dust from entering the interior of the acceptance space with the movement of the sheet metal, thereby helping to reduce the interference of dust on the acceptance.

[0094] As an optional embodiment, the airflow dust removal component further includes:

[0095] The collecting box 6 is fixed inside the installation chamber 102 , the top of the collecting box 6 is connected to the connecting pipe 503 , and the bottom of the collecting box 6 is connected to the first connecting channel 5 ;

[0096] The filter element 601 is fixed inside the collection box 6;

[0097] The airflow driven by the fan 502 is filtered by the filter element 601 when passing through the interior of the collection box 6. Thus, the airflow entering the detection space is filtered through the setting of the filter element 601 to prevent dust from entering the interior of the detection space along with the airflow, which is conducive to reducing the interference of dust on acceptance.

[0098] As an optional embodiment, the airflow dust removal component further includes:

[0099] Two negative pressure pumps 7 are symmetrically fixed on the top of the acceptance channel 101;

[0100] Two second communication channels 701 are fixed at both ends of the acceptance channel 101 respectively, and the input end of the negative pressure pump 7 is connected to the second communication channels 701;

[0101] A plurality of openings 702 are respectively opened on the side walls of the two second communication channels 701;

[0102] The negative pressure pump 7 can connect to the second connecting channel 701 to extract the gas inside the second connecting channel 701, so that the inside of the second connecting channel 701 is in a negative pressure state. When the airflow flows toward the moving space, under the guidance of the negative pressure, the airflow will flow toward the position of the opening 702, thereby guiding the flow of the airflow so that the airflow flows along the path of the detection space and the moving space. By controlling the negative pressure pump 7, the amount of guidance of the airflow can be controlled.

[0103] As an optional embodiment, the airflow dust removal component further includes:

[0104] The air inlet pipe 8 is fixed between the input end connected to the negative pressure pump 7 and the second connecting channel 701;

[0105] The exhaust pipe 801 is fixedly connected between the output end of the negative pressure pump 7 and the second communication channel 701;

[0106] The first connecting end tube 802 is fixed on the side wall of the air inlet tube 8;

[0107] The second connecting end pipe 803 is fixed on the side wall of the exhaust pipe 801;

[0108] Four control valves 804 are respectively fixed to the ends of the air inlet pipe 8 and the exhaust pipe 801, the inside of the first connecting end pipe 802, and the inside of the second connecting end pipe 803;

[0109] When only the air inlet pipe 8 and the control valve 804 inside the second connecting end pipe 803 are opened, the interior of the second connecting channel 701 is in a negative pressure state, which can guide the airflow. When only the air exhaust pipe 801 and the control valve 804 inside the first connecting end pipe 802 are opened, the interior of the second connecting channel 701 is in a high pressure state, which can discharge the airflow through the opening 702. Therefore, when the high-pressure airflow is discharged, the high-pressure airflow can impact the surface of the sheet metal to form an air curtain, which can clean the attached dust on the one hand and further prevent the entry of dust under the action of the air curtain.

[0110] As an optional embodiment, the partition assembly further includes:

[0111] A plurality of arc-shaped frames 9 are fixed to the bottom of each baffle 303;

[0112] A plurality of mounting slots 901 are respectively provided through the middle of each arc-shaped frame 9;

[0113] Several micro drive fans are installed inside each installation slot 901;

[0114] The arrangement of the arc frame 9 enables the sheet metal to push the bottom edge of the arc frame 9 when it moves, thereby not directly impacting the baffle 303, but having a force to push the arc frame 9 upward, which helps to avoid damage to the baffle 303 when the sheet metal moves. After the micro-drive fan is started, it can drive the airflow through the interior of the mounting groove 901, thereby forming an airflow guiding path, so that the airflow passes through each position evenly to guide the dust outflow, so as to reduce the entry of dust, thereby reducing the interference of dust on acceptance.

[0115] As an optional embodiment, the partition assembly further includes:

[0116] The distance sensor 10 is mounted on the side wall of one of the baffles 303;

[0117] The distance sensor 10 can detect the distance between the sheet metal and the baffle 303, so that when the arc frame 9 cannot move upward to make way by its own guidance, the baffle 303 can be driven upward to make way by the cylinder 3.

[0118] The working principle of the present invention is as follows: the conveying component transports the sheet metal parts that need to be inspected to the interior of the acceptance channel 101. When transported to the interior of the moving space, the partition component separates the moving space and the inspection space. As the sheet metal parts continue to be transported, the partition component opens, so that the moving space and the inspection space are connected. At this time, the airflow dust removal component is started synchronously. After the airflow dust removal component is started, the airflow is driven to flow along the direction of the inspection space and the moving space, which is conducive to avoiding the simultaneous entry of dust during the process of the sheet metal parts entering the acceptance space, causing dust to adhere to the sheet metal parts and affect the inspection results. Similarly, when the sheet metal parts are transported and discharged, the detector 103 can inspect and accept the surface of the sheet metal parts.

[0119] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
