Description

Technical Field

[0001] The present application relates to the field of material measurement or detection equipment, and in particular to a multi-station detection device. Background Art

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. It is widely used in many fields and plays a key role.

[0003] In related technologies, all kinds of products need to be tested for welding quality and molding quality after welding. Specifically, during the testing process, the corresponding products need to be clamped and positioned by positioning fixtures to effectively ensure the stability of the products during the testing process, thereby ensuring the accuracy of the product testing results.

[0004] However, the specifications, sizes and shapes of products processed and produced in daily life are all different, and some products even have irregular and special shapes. This requires that different positioning fixtures need to be replaced to adapt to different products when clamping and positioning products of different specifications, sizes and shapes, which leads to cumbersome steps and low efficiency when positioning different products, which is not conducive to daily product testing. Summary of the invention

[0005] The present application provides a multi-station inspection device, the purpose of which is to be able to process and position different products during daily inspection of different products without replacing positioning fixtures, thereby facilitating improving the efficiency of daily inspection of different product parts.

[0006] The present application provides a multi-station detection device, which adopts the following technical solution:

[0007] A multi-station detection device comprises an operating table, a detection table and a detection head, a mounting frame is fixed on the top of the operating table, the detection head is rotatably mounted on the mounting frame, a positioning assembly is added to the detection table, and the positioning assembly is used to position and clamp the product to be detected; the positioning assembly comprises a mounting plate, a limit plate and a plurality of positioning rods, a plurality of the positioning rods are all slidably inserted into the mounting plate along the vertical direction, the limit plate is fixedly connected to the mounting plate, and the limit plate is located below the mounting plate, the limit plate is used to limit the positioning rods, and the plurality of positioning rods are used to form a positioning cavity adapted to the product to be detected, and the positioning cavity is used to position the product to be detected;

[0008] The positioning rod is made of flexible material.

[0009] By adopting the above technical solution, the positioning cavity itself has no specific size and shape, and the specific size and shape of the positioning cavity is determined by the size and shape of the product itself. For example, a columnar product will form a columnar positioning cavity after squeezing the positioning rods on the mounting plate; a rectangular product will form a rectangular positioning cavity.

[0010] Even for irregular or special-shaped products, if conventional positioning fixtures are used, it is necessary to specially make fixtures that are compatible with the products, which is very troublesome. However, the above positioning method, when facing irregular or special-shaped products, will form an irregular-shaped positioning cavity that is compatible with the product, and then when facing products of different sizes, specifications and shapes, the positioning component can quickly and efficiently position the product, thereby significantly improving the efficiency of daily inspection of different types of products.

[0011] Preferably, a first drive motor is provided on the mounting frame, the drive end of the first drive motor faces downward, and an adapter plate is connected to the drive end in a horizontal direction, the top of the adapter plate is connected to the drive end of the first drive motor, the bottom of the adapter plate is integrally connected to a rotating plate, and the detection head is connected to the rotating plate.

[0012] By adopting the above technical solution, the first driving motor drives the rotating plate and the detection head to rotate synchronously while driving the adapter plate to rotate. This enables the detection angle of the detection head to be adjusted in multiple directions, which is conducive to improving the flexibility of the detection head in product detection.

[0013] Preferably, a screw rod is provided on the rotating plate, and both left and right ends of the screw rod are fastened to the rotating plate through corresponding mounting seats, one end of the screw rod is driven by a motor, and a sliding sleeve is sleeved on the screw rod, and the sliding sleeve is threadedly matched with the screw rod;

[0014] The bottom of the sliding sleeve is integrally connected with a first linkage rod in a vertical direction, a first linkage seat is integrally sleeved on the first linkage rod, a connecting plate is connected to the side of the first linkage seat away from the rotating plate, and the connecting plate includes a first plate body and a second plate body, one side of the first plate body is hingedly connected to the first linkage seat through a first hinge shaft, a second linkage rod is integrally connected to the bottom of the second plate body, a second linkage seat is integrally sleeved on the second linkage rod, a hinge seat is installed on the rotating plate, and the second linkage seat and the hinge seat are hingedly connected through a second hinge shaft; a rotating arm is integrally connected to the side of the second linkage seat away from the hinge seat, a driving cylinder is provided on the side of the rotating arm away from the second linkage seat, the cylinder body of the driving cylinder is fixed on the rotating arm, and the piston rod of the driving cylinder is connected to the detection head.

[0015] By adopting the above technical solution, while the rotating plate drives the detection head to rotate in the horizontal direction, the detection head and the rotating plate are set to be hinged by using the first linkage rod, the first linkage seat, the second linkage rod, the second linkage seat and the rotating arm, and the detection head can be extended and retracted by driving the cylinder. This enables the detection head to detect irregularly shaped products in all directions, thereby effectively improving the accuracy and rigor of the detection device, thereby effectively ensuring the molding quality of the product.

[0016] Preferably, a spring cover is sleeved on the piston rod of the driving cylinder, and the spring cover is arranged on the peripheral side of the detection head.

[0017] By adopting the above technical solution and covering the detection head with a spring cover, the detection head can be effectively prevented from being frequently exposed to the workshop air and contaminated by dust in the air, thereby facilitating the accuracy of the detection results of the product by the detection head.

[0018] Specifically, when testing a product, after the product is positioned by the positioning assembly, the spring cover and the detection head move toward the product under the drive of the drive cylinder, and the spring cover first abuts against the product. After the spring cover abuts against the product, the drive cylinder continues to drive, at which time the spring cover is squeezed and compressed until the detection head abuts against the side of the product to test the product. The spring cover can then be used to prevent dust from entering the detection head at any time without affecting the detection of the product by the detection head.

[0019] Preferably, a slag removal component is additionally provided in the spring cover, and the slag removal component is used to clean the welding slag around the part to be inspected on the product before the inspection head inspects the product.

[0020] By adopting the above technical solution, it is possible to effectively prevent welding slag from affecting the detection results when the detection head detects the product, which is beneficial to improving the accuracy of the detection results of the product by the detection head.

[0021] Preferably, the slag removal assembly comprises a sliding gear and a slag removal plate, the sliding gear is sleeved on the piston rod of the driving cylinder, a plurality of slag removal plates are provided, the plurality of slag removal plates are arranged on a side of the sliding gear close to the product, and the plurality of slag removal plates are clamped and distributed on the peripheral side of the detection head, and a brush for cleaning welding slag is integrally connected to a side of the slag removal plate away from the sliding gear;

[0022] An internal threaded hole is formed on the top of the spring cover, a screw rod is inserted into the internal threaded hole, one end of the screw rod passes through the internal threaded hole and abuts against a side of the sliding gear away from the slag removing plate, and the screw rod is used to drive the sliding gear to slide along the length direction of the driving cylinder piston rod; a return spring is sleeved on the circumference of the driving cylinder piston rod, and a side of the sliding gear away from the slag removing plate is connected to the end of the return spring;

[0023] A backing plate is provided between the end of the return spring and the sliding gear, and the backing plate is sleeved on the circumference of the piston rod of the driving cylinder;

[0024] The inner wall of the spring cover is provided with a plurality of rotating gears, the plurality of rotating gears are evenly distributed along the circumference of the spring cover, and the plurality of rotating gears are used to drive the sliding gear to rotate;

[0025] A second driving motor is installed on the top of the rotating gear, and the second driving motor is used to drive the rotating gear to rotate.

[0026] By adopting the above technical solution, compared with the traditional slag removal method, this setting method closely connects the slag removal and product testing of the product. The product can be tested by the detection head as soon as the slag removal is completed, thereby significantly shortening the interval between product slag removal and product testing, and effectively avoiding the possibility of secondary contamination of the product by dust in the air after the slag removal is completed. At the same time, from the completion of product slag removal to the detection process, the part of the product to be tested is always under the cover of the spring cover, which can further prevent the product from being exposed to dust in the air after the slag removal.

[0027] At the same time, before the three slag removing plates remove slag from the parts to be inspected of the product, the three slag removing plates are clamped and distributed around the detection head. After the three slag removing plates complete the removal of slag from the parts to be inspected of the product, the three slag removing plates can be reset to the sides of the detection head to clamp and position the detection head. In the process of the detection head inspecting the product, the three slag removing plates can always clamp and position the detection head, effectively ensuring the stability of the detection head during the product inspection process.

[0028] Preferably, the end of the detection head is configured to be conical, and ends of the plurality of slag removing plates that are away from each other are connected to the sliding gear via a torsion spring.

[0029] By adopting the above technical solution, the distance between the three slag removal plates can be adjusted. When the detection head extends into the cavity between the three slag removal plates, the peripheral side of the detection head squeezes the three slag removal plates, causing the three slag removal plates to expand outward in the direction away from each other. Since the end of the detection head is conical, as the sliding gear slides toward the direction close to the product, the three slag removal plates gradually detach from the detection head, and the distance between the three gradually decreases. When the three slag removal plates are completely detached from the detection head, the distance between the three is consistent with the size of the end of the detection head. Therefore, the range of the three slag removal plates to clean the welding slag can be consistent with the size of the detection head, which can effectively improve the accuracy of the detection result of the detection head on the product.

[0030] It should be noted here that the initial distance between the three slag removal plates can be assembled according to different outer diameters of the detection head, so that the initial distance between the three slag removal plates is consistent with the end size of the detection head, thereby ensuring that after the three slag removal plates are detached from the detection head, the distance between the three slag removal plates is consistent with the size of the detection head.

[0031] Preferably, a rotating seat is rotatably mounted on the detection platform, and the top of the rotating seat is connected to the bottom of the limiting plate.

[0032] By adopting the above technical solution, the rotating seat is used to drive the limit plate to rotate, and the limit plate drives the mounting plate to rotate synchronously during the rotation process. After the product to be detected is positioned on the mounting plate, the angle between the product and the detection head can be adjusted by rotating the mounting plate, which is beneficial to improve the overall adaptability of the detection device.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. The positioning cavity itself has no specific size and shape. The specific size and shape of the positioning cavity is determined by the size and shape of the product itself. For example, a columnar product will form a columnar positioning cavity after squeezing the positioning rods on the mounting plate; a rectangular product will form a rectangular positioning cavity.

[0035] Even for irregular or special-shaped products, if conventional positioning fixtures are used, it is necessary to specially make fixtures that match the products, which is very troublesome. However, the above positioning method, when facing irregular or special-shaped products, will form an irregular-shaped positioning cavity that matches the product, and then when facing products of different sizes, specifications and shapes, the positioning component can quickly and efficiently position the product, thereby significantly improving the efficiency of daily inspection of different types of products;

[0036] 2. Compared with the traditional slag removal method, this setting method closely links the slag removal and product testing of the product. The product can be tested by the detection head as soon as the slag removal is completed, which significantly shortens the interval between product slag removal and product testing, and effectively avoids the possibility of secondary contamination of the product by dust in the air after the slag removal is completed. At the same time, from the completion of product slag removal to the detection process, the part of the product to be tested is always under the cover of the spring cover, which can further prevent the product from being exposed to the air and contaminated by dust after the slag removal.

[0037] At the same time, before the three slag removal plates remove slag from the part to be inspected of the product, the three slag removal plates are clamped and distributed around the detection head. After the three slag removal plates have completed the removal of slag from the part to be inspected of the product, the three slag removal plates can be reset to the side of the detection head to clamp and position the detection head. In addition, during the process of the detection head inspecting the product, the three slag removal plates can always clamp and position the detection head, effectively ensuring the stability of the detection head during the product inspection process.

[0038] 3. When the detection head extends into the cavity between the three slag removal plates, the periphery of the detection head squeezes the three slag removal plates, causing the three slag removal plates to expand outward in the direction away from each other. Since the end of the detection head is conical, as the sliding gear slides toward the direction close to the product, the three slag removal plates gradually detach from the detection head, and the distance between them gradually decreases. When the three slag removal plates are completely detached from the detection head, the distance between them is consistent with the size of the end of the detection head. Therefore, the range of the three slag removal plates to clean the welding slag can be consistent with the size of the detection head, which can effectively improve the accuracy of the detection results of the detection head on the product.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0047] Example:

[0048] The present application discloses a multi-station detection device. Figure 1 and Figure 2 , including an operating table 1, a testing table 2 and a testing head 3. The operating table 1 is in the shape of a rectangular plate and is placed horizontally. The testing table 2 is in the shape of a disc and is fastened to the top of the operating table 1 in the horizontal direction by fastening bolts. A mounting frame 4 is fixed to the top of the operating table 1 in the vertical direction. The testing head 3 is arranged on the mounting frame 4 and can rotate on the mounting frame 4. At the same time, a positioning component 5 is added to the testing table 2. The positioning component 5 is used to position and clamp the product to be tested, so as to effectively ensure the stability of the testing head 3 during the product testing process, thereby ensuring the accuracy of the product testing results.

[0049] In this embodiment, the positioning components 5 on the testing platform 2 are set to three groups, and the three groups of positioning components 5 are evenly spaced along the periphery of the testing platform 2. The mounting racks 4 on the operating platform 1 are also set to three groups, and each group of positioning components 5 corresponds to a group of mounting racks 4. This enables the detection device to detect three groups of products at the same time, which is conducive to improving the efficiency of daily product detection.

[0050] Specifically, refer to Figure 1 and Figure 2The positioning assembly 5 includes a mounting plate 51, a limiting plate 52 and a plurality of positioning rods 53. The mounting plate 51 is horizontally arranged, the limiting plate 52 is located below the mounting plate 51, and the mounting plate 51 and the limiting plate 52 are connected by corresponding connecting rods. The mounting plate 51 is composed of two plates spaced apart from each other. The mounting plate 51 is provided with a plurality of through holes for the positioning rods 53 to pass through. The positioning rods 53 are inserted into the corresponding through holes on the mounting plate 51 in the vertical direction.

[0051] In this embodiment, the positioning rods 53 are installed in a slightly interference fit with the mounting plate 51 through corresponding through holes on the mounting plate 51. The initial state of the positioning rods 53 is that the top of the positioning rods 53 extends upward from the top of the mounting plate 51, and the bottom of the positioning rods 53 is flush with the bottom of the mounting plate 51.

[0052] Reference Figure 1 and Figure 2 Specifically, when testing the product, the product to be tested is placed on top of these positioning rods 53, and the part of the product to be tested faces upward. After the position of the product to be tested is placed, the staff continues to press the product on these positioning rods 53. During the pressing process, the product to be tested will continue to squeeze the positioning rods 53 in contact with it. These squeezed positioning rods 53 will gradually form positioning cavities 54 between the positioning rods 53 on the surrounding sides that are not squeezed by the product, and the product to be tested will be stuck in the positioning cavity 54. When the surrounding side of the product is completely stuck in the positioning cavity 54, stop pressing the product. In this state, the surrounding side of the product will be covered by the positioning cavities 54 on its left and right sides, and these positioning rods 53 distributed on the left and right sides of the product will clamp and position the product.

[0053] After the product is positioned in the positioning cavity 54, the staff will press the remaining positioning rods 53 that are not squeezed by the product to a position flush with the positioning rods 53 on the sides of the positioning cavity 54. The purpose of doing this is to effectively prevent the positioning rods 53 that are not squeezed from interfering with the detection head 3 during the product detection process when the product is trapped in the positioning cavity 54. After the product is positioned in the positioning cavity 54, the remaining positioning rods 53 that are not squeezed by the product are pressed to a position flush with the positioning rods 53 on the sides of the positioning cavity 54. This allows the part of the product to be detected to be completely exposed from these positioning rods 53, making it convenient for the detection head 3 to detect the part of the product to be detected; at the same time, the rest of the product is stuck in the positioning cavity 54 and is clamped and covered by the positioning rods 53 on the sides. It does not affect the detection of the part of the product to be detected by the detection head 3, and can effectively ensure the stability of the product during the detection process.

[0054] When the positioning rod 53 is pressed downward by the product, the limiting plate 52 can limit the positioning rod 53 to a certain extent, thereby effectively preventing the positioning rod 53 from being separated from the mounting plate 51 .

[0055] In this arrangement, the positioning cavity 54 itself has no specific size and shape, and the specific size and shape of the positioning cavity 54 is determined according to the size and shape of the product itself. For example, a columnar product will form a columnar positioning cavity 54 after squeezing the positioning rods 53 on the mounting plate 51; a rectangular product will form a rectangular positioning cavity 54.

[0056] Even for irregular or special-shaped products, if conventional positioning fixtures are used, it is necessary to specially make fixtures that are compatible with the products, which is very troublesome. However, the above positioning method, when facing irregular or special-shaped products, will form an irregular-shaped positioning cavity 54 that is compatible with the product, and then when facing products of different sizes and shapes, the positioning component 5 can quickly and efficiently position the product, thereby significantly improving the efficiency of daily inspection of different types of products.

[0057] In this embodiment, the positioning rod 53 is made of a flexible material. When the product contacts the positioning rod 53 , it can effectively prevent the positioning rod 53 from causing damage to the surrounding side of the product.

[0058] Further, refer to Figure 1 and Figure 2 A rotating seat 28 is installed on the detection table 2, and the rotating seat 28 can rotate in the horizontal direction. The top of the rotating seat 28 is connected to the bottom of the limit plate 52. The rotating seat 28 drives the limit plate 52 to rotate, and the limit plate 52 drives the mounting plate 51 to rotate during the rotation process. After the product to be detected is positioned on the mounting plate 51, the angle between the product and the detection head 3 can be adjusted by rotating the mounting plate 51, which is conducive to improving the overall adaptability of the detection device.

[0059] Specifically, the interior of the testing platform 2 is hollow, and a motor is installed at a position inside the testing platform 2 relative to the rotating seat 28. The driving end of the motor is connected to the bottom of the rotating seat 28 through a corresponding coupling shaft, and the rotating seat 28 is then driven by the motor to rotate in the horizontal direction.

[0060] Specifically, refer to Figure 1 and Figure 3 A fixing seat is welded on the mounting frame 4, and a first driving motor 6 is installed on the fixing seat. The driving end of the first driving motor 6 faces downward, and an adapter plate 7 is connected to the driving end in the horizontal direction. The top of the adapter plate 7 is connected to the driving end of the first driving motor 6, and the bottom of the adapter plate 7 is integrally connected to a rotating plate 8, and the detection head 3 is connected to the rotating plate 8. When the first driving motor 6 drives the adapter plate 7 to rotate, it simultaneously drives the rotating plate 8 and the detection head 3 to rotate. This allows the detection angle of the detection head 3 to be adjusted in multiple directions, which is conducive to improving the flexibility of the detection head 3 in product detection.

[0061] Further, refer to Figure 1 and Figure 3 , a screw rod 9 is added to the rotating plate 8 in the horizontal direction, and the left and right ends of the screw rod 9 are fastened to the rotating plate 8 through corresponding mounting seats, and one end of the screw rod 9 is driven by a motor, and the motor is connected to the mounting seat at one end of the screw rod 9. A sliding sleeve 10 is sleeved on the screw rod 9, and an internal thread is formed on the inner side of the sliding sleeve 10. The sliding sleeve 10 is sleeved on the screw rod 9 and is threaded with the screw rod 9. The screw rod 9 rotates under the drive of the motor, and the sliding sleeve 10 slides along the length direction of the screw rod 9.

[0062] Reference Figure 1 and Figure 3 The bottom of the sliding sleeve 10 is connected with a first linkage rod 11 in a vertical direction, and a first linkage seat 12 is integrally sleeved on the first linkage rod 11. A connecting plate 13 is connected to the side of the first linkage seat 12 away from the rotating plate 8. The connecting plate 13 includes a first plate body 131 and a second plate body 132. The first plate body 131 and the second plate body 132 are integrally connected, and the two are in an "L" shape as a whole. One side of the first plate body 131 is hingedly connected to the first linkage seat 12 through a first hinge shaft 14. The bottom of the second plate body 132 is integrally connected with a second linkage rod 15. A second linkage seat 16 is integrally sleeved on the second linkage rod 15. An articulated seat 17 is installed on the rotating plate 8. The second linkage seat 16 and the articulated seat 17 are articulated by a second articulated shaft 18. At the same time, a rotating arm 19 is integrally connected to the side of the second linkage seat 16 away from the articulated seat 17. The rotating arm 19 is in the shape of a rectangular parallelepiped plate. A driving cylinder 20 is provided on one side of the rotating arm 19 away from the second linkage seat 16 . The cylinder body of the driving cylinder 20 is welded to the rotating arm 19 , and the piston rod of the driving cylinder 20 is connected to the detection head 3 .

[0063] In this arrangement, while the rotating plate 8 drives the detection head 3 to rotate in the horizontal direction, the detection head 3 and the rotating plate 8 are connected in an articulated manner by using the first linkage rod 11, the first linkage seat 12, the second linkage rod 15, the second linkage seat 16 and the rotating arm 19, and the detection head 3 can be extended and retracted by driving the cylinder 20. This enables the detection head 3 to detect irregularly shaped products in all directions, thereby effectively improving the accuracy and rigor of the detection device, thereby effectively ensuring the molding quality of the product.

[0064] Further, refer to Figure 1 and Figure 4A spring cover 21 is sleeved on the piston rod of the driving cylinder 20, and the spring cover 21 is covered on the side of the detection head 3. Covering the detection head 3 with the spring cover 21 can effectively prevent the detection head 3 from being frequently exposed to the workshop air and contaminated by dust in the air, thereby facilitating the accuracy of the detection result of the detection head 3 on the product.

[0065] Specifically, when testing a product, after the product is positioned by the positioning assembly 5, the spring cover 21 and the detection head 3 move toward the product under the drive of the driving cylinder 20, and the spring cover 21 first abuts against the product. After the spring cover 21 abuts against the product, the driving cylinder 20 continues to drive, at which time the spring cover 21 is squeezed and compressed until the detection head 3 abuts against the product side to detect the product. The spring cover 21 can then be used to prevent dust from entering the detection head 3 at any time without affecting the detection of the product by the detection head 3.

[0066] Further, refer to Figure 4 and Figure 5 A slag removal component 22 is added to the spring cover 21. The slag removal component 22 can clean the welding slag around the to-be-detected part of the product before the detection head 3 detects the product, thereby effectively preventing the welding slag from affecting the detection result when the detection head 3 detects the product, thereby facilitating improving the accuracy of the detection result of the detection head 3 on the product.

[0067] Specifically, refer to Figure 4 and Figure 5 The slag removal assembly 22 includes a sliding gear 221 and a slag removal plate 222. The sliding gear 221 is sleeved on the piston rod of the driving cylinder 20. There are three slag removal plates 222. The three slag removal plates 222 are arranged on the side of the sliding gear 221 close to the product, and the three slag removal plates 222 are clamped and distributed around the detection head 3. The side of the slag removal plate 222 away from the sliding gear 221 is integrally connected with a brush for cleaning welding slag. The three slag removal plates 222 are all in a curved arc shape, and the three slag removal plates 222 are connected end to end. A cavity is formed between the three slag removal plates 222, and the detection head 3 is located in the cavity.

[0068] Specifically, when cleaning the welding slag, after the spring cover 21 is driven by the driving cylinder 20 to abut against the product, the sliding gear 221 slides on the piston rod of the driving cylinder 20 toward the product, and the sliding gear 221 drives the slag removal plate 222 to slide synchronously during the sliding process. When the slag removal plate 222 abuts against the part of the product to be inspected, the sliding gear 221 starts to rotate, and then the three slag removal plates 222 are synchronously driven to rotate through the sliding gear 221. When the three slag removal plates 222 rotate, the brushes on them can clean the welding slag remaining on the part of the product to be inspected. After the slag removal plate 222 cleans the welding slag, the sliding gear 221 is reset, and the three slag removal plates 222 are driven to re-clamp and distribute to the surrounding side of the detection head 3, and the detection head 3 is clamped and positioned. After the sliding gear 221 and the slag removal plate 222 are reset, the detection head 3 abuts against the part of the product to be inspected under the drive of the driving cylinder 20 for inspection.

[0069] Compared with the traditional slag removal method, this setting method closely connects the slag removal and product detection of the product. The product can be detected by the detection head 3 as soon as the slag removal is completed, thereby significantly shortening the interval between product slag removal and product detection, and effectively avoiding the possibility of secondary contamination of the product by dust in the air after the slag removal is completed. At the same time, after the product slag is completed and during the detection process, the part of the product to be detected is always under the cover of the spring cover 21, which can further prevent the product from being exposed to the air and contaminated by dust after the slag removal.

[0070] At the same time, before the three slag removing plates 222 remove slag from the part to be inspected of the product, the three slag removing plates 222 are clamped and distributed around the detection head 3. When the three slag removing plates 222 complete the removal of slag from the part to be inspected of the product, the three slag removing plates 222 can be reset to the side of the detection head 3 to clamp and position the detection head 3. In the process of the detection head 3 inspecting the product, the three slag removing plates 222 can always clamp and position the detection head 3, thereby effectively ensuring the stability of the detection head 3 during the process of inspecting the product.

[0071] Therefore, the slag removal plate 222 can not only remove slag and clean the part of the product to be inspected, but also can always clamp and position the detection head 3 when the detection head 3 is inspecting the product, effectively ensuring the stability of the detection head 3 during the product inspection process.

[0072] Specifically, refer to Figure 4 , Figure 5 as well as Figure 6, an internal threaded hole is formed through the top of the spring cover 21, a screw rod 23 is inserted into the internal threaded hole, one end of the screw rod 23 passes through the internal threaded hole and abuts against the side of the sliding gear 221 away from the slag removal plate 222. At the same time, a return spring 24 is sleeved around the piston rod of the driving cylinder 20, and the side of the sliding gear 221 away from the slag removal plate 222 is connected to the end of the return spring 24. When the screw rod 23 is rotated clockwise, the screw rod 23 moves downward and drives the sliding gear 221 to slide toward the direction close to the product. During the sliding process, the return spring 24 of the sliding gear 221 is in a stretched state; when the screw rod 23 is rotated counterclockwise, the screw 23 moves upward and the sliding gear 221 is reset under the action of the return spring 24 retracting.

[0073] A backing plate 25 is provided between the end of the return spring 24 and the sliding gear 221 . The backing plate 25 is also sleeved on the circumference of the piston rod of the driving cylinder 20 .

[0074] The inner wall of the spring cover 21 is provided with three rotating gears 26 through a connecting rod, and the three rotating gears 26 are evenly spaced along the circumference of the spring cover 21. The sliding gear 221 slides toward the product under the drive of the screw 23 until the circumference of the sliding gear 221 is meshed with the three rotating gears 26.

[0075] A second drive motor 27 is installed on the top of one of the rotating gears 26, and the rotating gear 26 rotates under the drive of the second drive motor 27. When the sliding gear 221 is meshed with the three rotating gears 26, the corresponding rotating gear 26 is driven to rotate by the second drive motor 27, and the sliding gear 221 is driven to rotate by the rotating gear 26. After the sliding gear 221 starts to rotate, it meshes with the other two rotating gears 26, and then synchronously drives the three rotating gears 26 to rotate at the same time. Driven by the three rotating gears 26, the sliding gear 221 rotates more stably.

[0076] After the sliding gear 221 is meshed with the three rotating gears 26, the three slag removal plates 222 abut against the part to be inspected of the product. As the sliding gear 221 rotates, the three slag removal plates 222 rotate synchronously and complete the cleaning of the welding slag on the part to be inspected of the product during the rotation process.

[0077] Since the three slag removal plates 222 are clamped and distributed on the outside of the detection head 3, the distance between the three slag removal plates 222 is actually larger than the outer diameter of the detection head 3. In this state, if the three slag removal plates 222 are detached from the detection head 3 to clean the welding slag, there is an error between the cleaning range of the three slag removal plates 222 and the detection range of the detection head 3: that is, the cleaning range of the three slag removal plates 222 is larger than the detection range of the detection head 3. At the same time, since the three slag removal plates 222 form a ring structure as a whole, this results in the position detected by the detection head 3 and the position of the three slag removal plates 222 cleaning the welding slag are not equal.

[0078] In order to effectively ensure that the positions where the three slag removal plates 222 clean the welding slag are consistent with the position detected by the detection head 3, the end of the detection head 3 is set to be conical, and at the same time, the tops of the three slag removal plates 222 at one end away from each other are connected to the sliding gear 221 through a torsion spring. This allows the distance between the three slag removal plates 222 to be adjusted.

[0079] When the detection head 3 extends into the cavity between the three slag removal plates 222, the circumferential side of the detection head 3 squeezes the three slag removal plates 222, so that the three slag removal plates 222 expand outward in the direction away from each other. Since the end of the detection head 3 is conical, as the sliding gear 221 slides toward the direction close to the product, the three slag removal plates 222 gradually detach from the detection head 3, and the distance between them gradually decreases. When the three slag removal plates 222 are completely detached from the detection head 3, the distance between them is consistent with the size of the end of the detection head 3. Therefore, the range of the three slag removal plates 222 cleaning the welding slag can be consistent with the size of the detection head 3, which can effectively improve the accuracy of the detection result of the detection head 3 on the product.

[0080] It should be noted here that the initial distance between the three slag removal plates 222 can be assembled according to the different outer diameters of the detection head 3, so that the initial distance between the three slag removal plates 222 is consistent with the end size of the detection head 3, thereby ensuring that after the three slag removal plates 222 are detached from the detection head 3, the distance between the three slag removal plates 222 is consistent with the size of the detection head 3.

[0081] The implementation principle of a multi-station detection device in the embodiment of the present application is:

[0082] Specifically, when testing a product, the product to be tested is placed on top of these positioning rods 53, and the part of the product to be tested faces upward. After the position of the product to be tested is placed, the staff continues to press the product on these positioning rods 53. During the pressing process, the product to be tested will continue to squeeze the positioning rods 53 in contact with it, and these squeezed positioning rods 53 will gradually form positioning cavities 54 between the positioning rods 53 on the surrounding side that are not squeezed by the product, and the product to be tested will be stuck in the positioning cavity 54. When the surrounding side of the product is completely stuck in the positioning cavity 54, the pressing of the product is stopped. In this state, the surrounding side of the product will be covered by the positioning cavities 54 on its left and right sides, and these positioning rods 53 distributed on the left and right sides of the product will clamp and position the product.

[0083] After the product is positioned in the positioning cavity 54, the staff will press the remaining positioning rods 53 that are not squeezed by the product to a position flush with the positioning rods 53 on the sides of the positioning cavity 54. The purpose of doing this is to effectively prevent the positioning rods 53 that are not squeezed from interfering with the detection head 3 during the product detection process when the product is trapped in the positioning cavity 54. After the product is positioned in the positioning cavity 54, the remaining positioning rods 53 that are not squeezed by the product are pressed to a position flush with the positioning rods 53 on the sides of the positioning cavity 54. This allows the part of the product to be detected to be completely exposed from these positioning rods 53, making it convenient for the detection head 3 to detect the part of the product to be detected; at the same time, the rest of the product is stuck in the positioning cavity 54 and is clamped and covered by the positioning rods 53 on the sides. It does not affect the detection of the part of the product to be detected by the detection head 3, and can effectively ensure the stability of the product during the detection process.

[0084] When the positioning rod 53 is pressed downward by the product, the limiting plate 52 can limit the positioning rod 53 to a certain extent, thereby effectively preventing the positioning rod 53 from being separated from the mounting plate 51 .

[0085] In this arrangement, the positioning cavity 54 itself has no specific size and shape, and the specific size and shape of the positioning cavity 54 is determined according to the size and shape of the product itself. For example, a columnar product will form a columnar positioning cavity 54 after squeezing the positioning rods 53 on the mounting plate 51; a rectangular product will form a rectangular positioning cavity 54.

[0086] Even for irregular or special-shaped products, if conventional positioning fixtures are used, it is necessary to specially make fixtures that are compatible with the products, which is very troublesome. However, the above positioning method, when facing irregular or special-shaped products, will form an irregular-shaped positioning cavity 54 that is compatible with the product, and then when facing products of different sizes and shapes, the positioning component 5 can quickly and efficiently position the product, thereby significantly improving the efficiency of daily inspection of different types of products.

[0087] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
