The device includes a base and a conveying assembly, disposed inside the base and used to convey flange side plates to be tested. The conveying assembly includes an electric lifting platform and a slide table sliding on the top of the electric lifting platform. A turntable rotates on one side of the top of the slide table.

Description

Technical Field

[0001] This invention relates to the field of plastic spool testing technology, and more specifically, to a testing device and method for plastic spools. Background Technology

[0002] Plastic reels are the core load-bearing components in the cable winding, transfer, and storage processes. The entire reel is integrally injection molded from a cylindrical body and two circular flange side plates. The flange side plates on both sides of the reel have regularly distributed openings. The outer circle contour, end face flatness, and opening position accuracy of the flange side plates directly determine the neatness of the wire winding. If the flange side plates have defects such as outer circle deformation, opening offset, or end face warping, the wire is prone to problems such as deviation, overlap, and scratches during the winding process.

[0003] The flange side plate inspection device for plastic wire reels is designed to detect deformation defects in the flange side plates. It collects data such as the outer circle contour dimensions, the position of the openings, and the flatness of the end face of the flange side plate. It determines whether there are unqualified issues such as outer circle warping, opening misalignment, and uneven deformation of the plate surface. It replaces traditional manual visual inspection, quantifies flange side plate deformation defects, and improves the accuracy of the shape inspection of plastic wire reel flange side plates.

[0004] However, during flange side plate inspection, the clamped end face is completely blocked by the main equipment component, and the equipment can only collect data from the exposed end face, making it impossible to complete the inspection of both end faces of the flange side plate. To complete the inspection of the other end face, the flange side plate needs to be manually disassembled and flipped, which is a cumbersome operation. Furthermore, there is no circumferential positioning restriction during the flange side plate disassembly and flipping process, and the circumferential angle of the connection hole is very easy to deviate. During the secondary clamping, the equipment mounting base and drive mechanism block the insertion and docking area, and the operator cannot visually check the fit status and can only rely on tactile alignment, which frequently results in insertion misalignment and incomplete insertion, increasing the difficulty of flange side plate clamping operation. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a detection device and detection method for plastic coils.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detection device for plastic coils, comprising a base.

[0007] A conveying assembly, located inside the base, is used to convey the flange side plate to be inspected. The conveying assembly includes an electric lifting platform and a slide table that slides on the top of the electric lifting platform. A turntable rotates on one side of the top of the slide table, and a pneumatic clamp is embedded in one side of the top of the turntable. The pneumatic clamp is used to vertically position the flange side plate. A positioning mechanism is hinged to the other side of the top of the turntable. The positioning mechanism defines the orientation of the vertically positioned flange side plate and the connecting hole.

[0008] The main assembly is disposed on the top of the base and is used for positioning and rotating the flange side plate. The main assembly includes a mounting base mounted on the top of the base and a drive mechanism mounted on the mounting base, and the output end of the drive mechanism.

[0009] A connecting center column is provided, and a connecting ring is sleeved on the outer wall of the center column. Two spring columns are symmetrically connected to the side wall of the connecting ring. The diameter of the two spring columns is adapted to the diameter of the connecting hole on the side wall of the flange side plate. When the flange side plate is transported to the position of the main component, the two spring columns are used to position the flange side plate.

[0010] The drive mechanism is equipped with a first detection component and a second detection component on one side and the top, respectively. The first detection component and the second detection component respectively detect the flatness of the center position and the outer wall deformation of the outer edge of the flange side plate. After the detection is completed, the connecting hole is positioned and rotated 180 degrees using the conveying component, and then repositioned for detection.

[0011] The present invention is further configured such that: the positioning mechanism includes a hinge plate hinged to the top of the slide table and a rotating rod rotating on the side wall of the hinge plate; the rotating rod passes through the hinge plate; one end of the rotating rod is connected to a rotating plate; and two insert rods are symmetrically installed on the side wall of the rotating plate; the diameter of the two insert rods is adapted to the diameter of the connecting hole on the side wall of the flange side plate.

[0012] The present invention is further configured such that: the outer wall of the ends of both insertion rods is provided with a first tapered portion, and the inner wall of the ends of the insertion rods is provided with a second tapered portion.

[0013] The invention is further configured such that: an arc-shaped groove is provided on the side wall of the hinge plate, a locking rod slides inside the arc-shaped groove, a swing plate is connected to the outer wall of the rotating rod, a locking rod is provided on the side wall of the swing plate, and the end of the locking rod is inserted into the inside of the arc-shaped groove.

[0014] The invention is further configured such that a positioning block slides inside the arc-shaped groove, the positioning block being used to limit the sliding stroke of the locking rod.

[0015] The present invention is further configured such that: a bracket is installed on the top of the electric lifting platform, the length of the bracket is adapted to the length of the top surface of the electric lifting platform, and the slide slides on the top of the bracket.

[0016] The present invention is further configured such that: the first detection component includes a support rod horizontally mounted on the side wall of the drive mechanism, a first swing arm horizontally sliding on the outer side wall of the support rod, a second swing arm horizontally hinged to the end of the first swing arm, an industrial camera and a center displacement sensor respectively mounted on the top and bottom of the end of the second swing arm, the industrial camera being used to capture the position and size of the opening on the side wall of the flange side plate, and the center displacement sensor being used to detect the flatness of the center position of the flange side plate.

[0017] The present invention is further configured such that: a pivot is provided at the hinge of the first swing arm and the second swing arm, and a locking member is threadedly connected to the outer side wall end of the pivot.

[0018] The present invention is further configured such that: the second detection component includes an L-frame installed on the top of the drive mechanism, an end face displacement sensor is horizontally installed at the end of the L-frame, and an outer circle displacement sensor is vertically installed downward at the end of the L-frame, the end face displacement sensor and the outer circle displacement sensor respectively detect the flatness of the outer edge of the flange side plate and the deformation of the outer wall.

[0019] A method for detecting plastic wire reels, using the detection device for plastic wire reels as described above, includes the following steps: S1. After the flange side plate comes off the injection molding line, it is transported to the base position. The flange side plate is placed on the top of the turntable and the angle is adjusted. After the adjustment is completed, the electric lifting platform drives the slide, turntable and flange side plate to move up as a whole until the center hole of the flange side plate is opposite to the center column. Then the slide slides on the top of the electric lifting platform, causing the flange side plate to move closer to the center column. Two of the connecting holes of the flange side plate are connected with two spring columns, and the conical surface of the center column is at the center hole of the flange side plate. The drive mechanism drives the center column and connecting ring to rotate, and the two spring columns rotate around, causing the flange side plate to rotate as a whole.

[0020] S2. During the rotation of the flange side plate, the first detection component and the second detection component work together to detect the flatness of the center position and the outer ring position of the flange side plate, respectively.

[0021] S3. After the flange side plate inspection is completed, the flange side plate is picked up and transferred using the conveying assembly. With the help of the staff, the flange side plate is rotated 180 degrees and reconnected with the two spring columns. Then, the blind spot position of the flange side plate during the first inspection is re-inspected. After all the inspections are completed, the staff removes the flange side plate from the line and re-inspects the new flange side plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting a central column and a spring column, the spring column can be radially elastically extended and retracted. When clamping, the central column is axially positioned by pressing the conical surface against the center hole of the flange side plate. The spring column is inserted into the connecting hole on the end face of the flange side plate to transmit torque and drive rotation. This avoids the influence of self-weight sagging on the test data when placed horizontally, and at the same time avoids the deformation caused by the clamping force acting directly on the plastic center hole, thus ensuring the authenticity of the flatness and hole position accuracy test results.

[0023] (2) By setting up a slide, turntable and pneumatic clamp, when the flange side plate needs to be flipped for re-inspection after single-sided inspection, the pneumatic clamp holds and fixes the flange side plate, the turntable drives the flange side plate in the clamped state to rotate 180 degrees to complete the flipping, and the slide horizontally feeds and pushes the flange side plate to be re-inserted into the spring column to complete the secondary clamping, thereby replacing the purely manual operation of manual removal, flipping and alignment, reducing the labor intensity of operators, shortening the auxiliary time of flipping and clamping, and ensuring that the flange side plate always maintains a vertical posture during the transfer and flipping process, which is convenient for secondary clamping and docking.

[0024] (3) By setting a positioning mechanism, a second tapered part is opened on the inner side of the end of the insertion rod. After the single-sided inspection of the flange side plate is completed and the turntable receives it, the hinge plate swings to the vertical state so that the insertion rod and the flange side plate connection hole remain coaxial. The axial feed of the rotating rod drives the insertion rod to press back the spring column and insert it into the flange side plate connection hole, thereby forming a double circumferential positioning with the pneumatic clamp, avoiding circumferential deflection of the flange side plate during flipping and transportation, and providing hole position reference for subsequent secondary clamping.

[0025] (4) When switching the connection hole position for secondary clamping after the flange side plate is flipped over, the rotating rod drives the flange side plate to adjust the circumferential angle. The locking rod slides along the arc groove and the rotation stroke is limited by the positioning block, so that the adjacent connection hole is aligned with the spring column. Thus, there is no need for manual alignment by feel. Even if there is a visual obstruction at the clamping position, the connection hole position can be quickly adjusted and changed, reducing the difficulty of operation. At the same time, the blind connection hole during the first inspection can be calibrated to eliminate the blind inspection area. Attached Figure Description

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0042] Please see Figures 1-13 The present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 2 A testing device for plastic coils includes a base 1, a conveying assembly 2 and a main assembly 3 mounted on the top of the base 1. The conveying assembly 2 is used for feeding and transferring materials, and the main assembly 3 is used for positioning and rotating a flange side plate 6. That is, after receiving the flange side plate 6 to be tested, the flange side plate 6 can be moved along the length of the base 1 to the clamping station of the main assembly 3 to realize the feeding and transfer before testing and match the station requirements of the subsequent testing process.

[0043] To avoid the situation in the existing method where the flange side plate 6 is placed horizontally for testing, causing the outer edge of the flange side plate 6 to sag and affect the test data, the flange side plate 6 is now placed vertically using the main body assembly 3. The specific structure of the main body assembly 3 is as follows: See Figure 1 , Figure 2 and Figure 4 The main component 3 includes a mounting base 31 mounted on the top of the base 1 and a drive mechanism 32 mounted on the mounting base 31. The drive mechanism 32 can be a drive motor, which is not specifically limited here. The output end of the drive mechanism 32 is connected to the central column 34. The central column 34 is used to position the flange side plate 6. The drive mechanism 32 outputs rotational power to drive the central column 34 to rotate, thereby driving the flange side plate 6 to rotate synchronously. A first detection component 4 and a second detection component 5 are respectively installed on one side and the top of the drive mechanism 32. The first detection component 4 corresponds to the central area of ​​the flange side plate 6 and is used to detect the flatness of the end face of the central part. The second detection component 5 corresponds to the outer edge area of ​​the flange side plate 6 and is used to detect the flatness of the end face and the radial deformation of the outer circle.

[0044] However, this inspection process is set at the off-line station of the plastic flange side plate 6 injection molding process. After the flange side plate 6 is injection molded and off the line, the shape and position accuracy is directly inspected without any additional intermediate transfer links. The flange side plate 6 that passes the inspection then enters the subsequent plastic coil assembly process and the finished product dynamic balance inspection process. Defective products are directly rejected online to avoid defective flange side plates 6 flowing into downstream processes and causing waste of assembly materials and time.

[0045] In conventional methods, flange side plate 6 is inspected directly after injection molding and cooling, and its center hole needs to be clamped and positioned during inspection. However, since flange side plate 6 is made entirely of plastic, if the center hole has defects after injection molding, it may result in a non-circular hole. If the center hole is clamped, this non-circular hole will be stretched open, affecting the clamping angle of flange side plate 6 and causing distortion in the flatness and hole position accuracy test results. If the center hole is not defective, clamping and positioning it using conventional inspection methods may also cause deformation of the center hole due to stress. Deformation of the center hole will affect the rotational stability of the finished plastic coil during subsequent winding assembly, and this effect is irreversible.

[0046] For this purpose, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 The diameter of the central column 34 is set larger than the diameter of the central hole of the flange side plate 6, and the end of the central column 34 is tapered. A connecting ring 35 is fitted on the outer wall of the central column 34. Two spring columns 33 are symmetrically connected to the side wall of the connecting ring 35. The diameter of the two spring columns 33 is adapted to the diameter of the connecting hole on the side wall of the flange side plate 6. The connecting ring 35 rotates synchronously with the central column 34. The symmetrically arranged spring columns 33 on the connecting ring 35 can elastically expand and contract radially. When the flange side plate 6 is clamped, the spring columns 33 are inserted into the connecting hole on the end face of the flange side plate 6, while the end of the central column 34 rests against the central hole of the flange side plate 6. When the central column 34 rotates, it drives the two spring columns 33 to move. The spring columns 33 transmit torque through the hole wall of the connecting hole, causing the flange side plate 6 to rotate. The positioning reference is transferred from the central hole to the connecting hole on the end face, avoiding the clamping force acting directly on the central hole and preventing the central hole from being deformed by force. See reference. Figure 13 The connecting hole is used to install the positioning stud between the coil body and the flange side plate. Whether the connecting hole is deformed by force does not affect the accurate installation of the positioning stud, nor does it affect the rotational stability of the finished plastic coil during subsequent winding assembly.

[0047] See Figure 2 and Figure 3The first detection component 4 includes a support rod 41 horizontally mounted on the side wall of the drive mechanism 32. A first swing arm 42 slides horizontally on the outer side wall of the support rod 41. A second swing arm 43 is horizontally hinged to the end of the first swing arm 42. An industrial camera 45 and a center displacement sensor 46 are respectively mounted on the top and bottom of the end of the second swing arm 43. The industrial camera 45 is used to capture the position and size of the opening on the side wall of the flange side plate 6. The center displacement sensor 46 is used to detect the flatness of the center position of the flange side plate 6. A rotating shaft is provided at the hinge of the first swing arm 42 and the second swing arm 43. A locking member 44 is threadedly connected to the outer side wall end of the rotating shaft. The locking member 44 can be a fixing bolt, which is not specifically limited here. The first swing arm 42 can slide horizontally along the support rod 41 to adjust the radial position of the industrial camera 45 and the center displacement sensor 46 to adapt to different... The flange side plate 6 has a diameter of [diameter missing]. The second swing arm 43 is hinged to the first swing arm 42 and can swing horizontally around the hinge axis to adjust the circumferential position and detection angle of the industrial camera 45 and the center displacement sensor 46. During detection, the industrial camera 45 faces the end face of the flange side plate 6, and the center displacement sensor 46 is aligned with the center area of ​​the flange side plate 6. After adjustment, the operator tightens the locking part 44, which increases the friction between the hinge surfaces of the first swing arm 42 and the second swing arm 43 through axial pressure, locking the relative angle between the two swing arms. This ensures the stability of the positions of the industrial camera 45 and the center displacement sensor 46 during detection and avoids positional deviation affecting data accuracy. When it is necessary to disassemble the flange side plate 6, the operator only needs to loosen the locking part 44 and then swing the second swing arm 43 to the range of the base 1.

[0048] During the inspection of flange side plate 6, drive mechanism 32 drives flange side plate 6 to rotate, industrial camera 45 continuously captures the shape of connection hole of flange side plate 6, obtains connection hole size and roundness parameters through image recognition, center displacement sensor 46 collects axial runout of end face, and calculates flatness data of center area.

[0049] See Figure 2 and Figure 5The second detection component 5 includes an L-frame 51 mounted on the top of the drive mechanism 32. An end face displacement sensor 52 is horizontally mounted at the end of the L-frame 51, and an outer circle displacement sensor 53 is vertically mounted downward at the end of the L-frame 51. The end face displacement sensor 52 and the outer circle displacement sensor 53 respectively detect the flatness of the outer edge of the flange side plate 6 and the deformation of the outer wall. The L-frame 51 is fixed on the top of the drive mechanism 32, providing a mounting point for the end face displacement sensor 52 and the outer circle displacement sensor 53. The end face displacement sensor 52 is arranged horizontally, with its detection end aligned with the outer edge end face of the flange side plate 6. When the flange side plate 6 rotates, it collects the axial runout of the end face to detect the flatness of the outer edge area. The outer circle displacement sensor 53 is arranged vertically downward, with its detection end aligned with the outer cylindrical surface of the flange side plate 6. When the flange side plate 6 rotates, it collects the radial runout of the outer circle to detect the roundness deformation and coaxiality error of the outer circle.

[0050] Specifically, after the flange side plate 6 comes off the injection molding machine, the conveying assembly 2 moves the injection-molded flange side plate 6 along the base 1 to the position of the main assembly 3. The center hole of the flange side plate 6 is aligned with the tapered end of the center column 34 to complete axial positioning. The spring column 33 on the connecting ring 35 is inserted into the connecting hole on the end face of the flange side plate 6. Then, the operator swings the second swing arm 43. The second swing arm 43 can swing around the hinge axis to adjust the circumferential angle. The industrial camera 45 faces the end face of the flange side plate 6, and the center displacement sensor 46 is aligned with the center area of ​​the flange side plate 6. After the adjustment is completed, the operator tightens the locking part 44. The axial pressure can increase the friction between the hinge surfaces of the first swing arm 42 and the second swing arm 43, lock the relative angle between the two swing arms, and ensure the stability of the position of the industrial camera 45 and the center displacement sensor 46 during the detection process. The end face displacement sensor 52 and the outer circle displacement sensor 53 are respectively positioned at the outer edge and outer wall of the flange side plate 6.

[0051] Then, the drive mechanism 32 outputs rotational power, which drives the connecting ring 35 and the spring column 33 to rotate synchronously through the central column 34. The spring column 33 transmits torque through the wall of the connecting hole, causing the flange side plate 6 to rotate at a constant speed. During this process, the central column 34 only abuts against the central hole with its conical surface and does not apply radial expansion force to the central hole, thus avoiding deformation of the plastic central hole due to clamping force. This solves the problem of distortion in the flatness and hole position accuracy detection results caused by traditional central hole clamping.

[0052] During the rotation of the flange side plate 6, the center displacement sensor 46 of the first detection component 4 collects the axial runout of the center area of ​​the flange side plate 6, and analyzes it to obtain the flatness of the end face of the center area. The industrial camera 45 continuously captures images of the connecting hole, and obtains the size and roundness parameters of the connecting hole through image recognition. The end face displacement sensor 52 of the second detection component 5 collects the axial runout of the outer edge end face of the flange side plate 6 and detects the flatness of the outer edge area. The outer circle displacement sensor 53 collects the radial runout of the outer cylindrical surface of the flange side plate 6 and detects the roundness deformation and coaxiality error of the outer circle. Multiple shapes and positions can be detected simultaneously in one clamping.

[0053] Staff members sort qualified and unqualified products based on the test data. Unqualified products can be removed online in real time to prevent unqualified flange side plates from flowing into the downstream assembly process, reduce the waste of materials and time, and reduce the analysis variables for subsequent dynamic balance testing of finished products.

[0054] In the second embodiment, the flange side plate 6 is inserted and clamped to the spring column 33 through the connecting hole on one side of the end face. The end face on the clamping side is blocked by the main body component 3, so data on this side end face cannot be collected. Only the exposed end face away from the main body component 3 can be detected. If a manual flipping method is used, the flange side plate 6 needs to be pulled out from the spring column 33, flipped 180 degrees and then re-aligned and inserted. The manual alignment efficiency is low and affects the overall detection cycle.

[0055] Therefore, the conveying component 2 has been further improved, and the specific structure of the improved conveying component 2 is as follows: See Figure 2 and Figure 8 The conveying assembly 2 includes an electric lifting platform 21 and a slide 23 that slides on the top of the electric lifting platform 21. A bracket 22 is installed on the top of the electric lifting platform 21. The length of the bracket 22 is adapted to the length of the top surface of the electric lifting platform 21. The slide 23 slides on the top of the bracket 22. A turntable 24 rotates on one side of the top of the slide 23. A pneumatic clamp 26 is embedded in one side of the top of the turntable 24. The pneumatic clamp 26 is used to vertically position the flange side plate 6.

[0056] See Figure 2 and Figure 8The electric lifting platform 21 can drive the bracket 22, slide 23, and turntable 24 to rise and fall vertically as a whole, adjusting the height of the flange side plate 6 and ensuring that the center hole of the flange side plate 6 is coaxially aligned with the center column 34. The bracket 22 provides a sliding guide for the slide 23, which can slide horizontally back and forth along the bracket 22 to achieve the close clamping and unloading of the flange side plate 6. The turntable 24 can rotate around the vertical axis to adjust the initial circumferential angle of the flange side plate 6 and also provide rotational freedom for the flange side plate 6 to flip. The pneumatic clamp 26 is embedded in the turntable 24 and can clamp from the outer circle or end face of the flange side plate 6 to ensure that the flange side plate 6 maintains a stable vertical posture during the transfer and flipping process and will not tilt or deviate.

[0057] After the flange side plate 6 completes single-sided inspection, the staff pushes the slide table 23 to slide horizontally along the bracket 22 to directly below the flange side plate 6. The electric lifting platform 21 drives the bracket 22, slide table 23 and turntable 24 to rise as a whole, so that the pneumatic clamp 26 on the turntable 24 lifts and clamps the flange side plate 6. Then the staff pushes the flange side plate 6 back from the spring column 33. At this time, the slide table 23 retracts horizontally in sync, and the flange side plate 6 is released from the spring column 33, completing the unloading action.

[0058] When the flange side plate 6 needs to be flipped, the operator supports the flange side plate 6 and rotates it. The turntable 24 rotates 180 degrees around the vertical axis, causing the flange side plate 6 in the clamped state to flip simultaneously. Then, the slide table 23 feeds and pushes the flipped flange side plate 6 back to be aligned and inserted into the spring column 33, completing the secondary clamping. Subsequently, the first detection component 4 and the second detection component 5 work together to further supplement the detection blind area on the flange side plate 6. This setting replaces the purely manual operation of manual removal, flipping, and alignment, reducing the labor intensity of the operator, shortening the auxiliary time for flipping and clamping, and the pneumatic clamp 26 can stably clamp the flange side plate 6, ensuring that the flange side plate 6 always maintains a vertical posture and the connection hole position of the flange side plate 6 remains unchanged during the transfer and flipping process, which facilitates the second clamping.

[0059] Meanwhile, during the process of removing and flipping the flange side plate 6, there is no circumferential positioning constraint, and the circumferential angle of the connecting hole is prone to deviation. During the secondary clamping, the mounting base 31 and drive mechanism 32 of the main component 3 block the docking position of the spring column 33. The operator cannot intuitively observe the insertion and mating state and can only align by feel, which easily leads to misalignment or incomplete insertion, increasing the difficulty of clamping.

[0060] For further details, please refer to [link / reference]. Figure 8A positioning mechanism 25 is hinged to the other side of the top of the turntable 24. The positioning mechanism 25 limits the orientation of the vertically positioned flange side plate 6 and the connecting hole. That is, the positioning mechanism 25 cooperates with the pneumatic clamp 26 to further limit the flange side plate 6 circumferentially and fix the circumferential angle of the connecting hole. This ensures that the circumferential position of the connecting hole corresponds to the position of the spring column 33 when the flange side plate 6 is flipped and transferred, avoiding hole offset and realizing rapid docking of secondary clamping.

[0061] See Figures 8-12 The positioning mechanism 25 includes a hinge plate 251 hinged to the top of the slide table 23 and a rotating rod 252 rotating on the side wall of the hinge plate 251. The rotating rod 252 passes through the hinge plate 251. The hinge plate 251 can swing between a horizontal and a vertical state around the hinge axis. In the non-working state, it is laid flat for storage, and in the working state, it is erected for positioning. The rotating rod 252 can move axially and rotate circumferentially relative to the hinge plate 251. One end of the rotating rod 252 is connected to a rotating plate 253. Two insert rods 254 are symmetrically installed on the side wall of the rotating plate 253. When the rotating rod 252 moves, it drives the rotating plate 253 and the insert rods 254 to move synchronously. The outer diameter of the rod 254 is adapted to the inner diameter of the connecting hole of the flange side plate 6. After being inserted into the connecting hole, it can restrict the circumferential rotation of the flange side plate 6. The outer wall of the end of each of the two rods 254 is provided with a first tapered part 255, and the inner wall of the end of the rod 254 is provided with a second tapered part 256. The first tapered part 255 is used to provide guidance when inserted into the connecting hole of the flange side plate 6, so that it can be smoothly inserted even if there is a slight deviation in the hole position. The second tapered part 256 is used to guide when docking with the end of the spring column 33. It can push the spring column 33 radially back along the tapered surface, so that the rod 254 can be smoothly fitted into and inserted into the connecting hole, thus completing the connection of the flange side plate 6.

[0062] Specifically, after the flange side plate 6 completes single-sided inspection and is received by the turntable 24, the operator swings the hinge plate 251 to a vertical position, so that the insertion rod 254 and the connection hole of the flange side plate 6 are coaxial, and pushes the rotating rod 252 to feed axially. The second tapered part 256 on the inner side of the insertion rod 254 first contacts the tapered surface of the end of the spring column 33. With the feeding thrust, the spring column 33 is radially pressed back along the tapered surface. The insertion rod 254 is sleeved on the outside of the spring column 33 and continues to feed, and finally inserts into the connection hole of the flange side plate 6. Through the insertion and engagement of the insertion rod 254 and the connection hole, the flange side plate 6 is still circumferentially constrained after it is separated from the main body component 3. The pneumatic clamp 26 simultaneously clamps the outer circle of the flange side plate 6 to form a double positioning, which avoids the flange side plate 6 from circumferential deflection during flipping and transportation, and provides a hole position reference for subsequent secondary clamping.

[0063] Then, the slide table 23 drives the flange side plate 6 to retract. With the help of the staff, the flange side plate 6 is rotated 180 degrees and flipped over using the turntable 24. Then it is reconnected and the connecting hole of the flange side plate 6 is fitted onto the outer wall of the spring column 33. Then the positions of the first detection component 4 and the second detection component 5 are adjusted to further perform blind zone detection on the flipped flange side plate 6.

[0064] See Figures 8-12 The hinge plate 251 has an arc-shaped groove 257 on its side wall. A locking rod 258 slides inside the arc-shaped groove 257. A swing plate is connected to the outer wall of the rotating rod 252. The side wall of the swing plate is provided with a locking rod 258. The end of the locking rod 258 is inserted into the arc-shaped groove 257. A positioning block 259 slides inside the arc-shaped groove 257. The positioning block 259 is used to limit the sliding stroke of the locking rod 258. This sliding stroke is set to be the same as the distance between two adjacent connecting holes in the flange side plate 6. The locking rod 258 rotates with the plate. The rod 252 rotates synchronously and slides along the arc groove 257 on the hinge plate 251. The arc groove 257 provides guidance for the rotation of the rod 252. The positioning block 259 can be adjusted and fixed in the arc groove 257 to limit the sliding end point of the locking rod 258, that is, to limit the maximum rotation angle of the rod 252 and avoid excessive rotation. The cooperation between the locking rod 258 and the arc groove 257 can ensure the stability of the rod 252 during rotation and prevent radial displacement when the insertion rod 254 drives the flange side plate 6 to rotate.

[0065] Specifically, based on the distribution specifications of the connecting holes on the flange side plate 6, the staff adjusts the position of the positioning block 259, that is, the positioning block 259 extends and slides along the arc from one end of the arc groove 257, and the sliding distance is the distance between two adjacent connecting holes on the flange side plate 6. Then the positioning block 259 is locked by the lock nut. This adjustment can be used to continuously inspect the flange side plate 6 after the injection molding machine comes off the line until the product after the injection molding machine comes off the line is adjusted, and then the position of the positioning block 259 is readjusted.

[0066] After the position of the positioning block 259 is adjusted, the positioning mechanism 25 waits to adjust the flange side plate 6 that needs to be flipped.

[0067] After the positioning mechanism 25 completes the circumferential constraint on the flange side plate 6, the operator rotates the flange side plate 6 180 degrees using the turntable 24. During this process, the positioning mechanism 25 continuously constrains the flange side plate 6. After the flipping is completed, the operator controls the pneumatic clamp 26 to release the flange side plate 6, and then adjusts the circumferential angle of the flange side plate 6 by rotating the rotating rod 252. The locking rod 258 slides along the arc groove 257 and limits the rotation stroke through the positioning block 259. At this time, the connecting hole of the flange side plate 6 during single-sided inspection is misaligned with the spring column 33, while the adjacent connecting hole is aligned with the spring column 33. At this time, the pneumatic clamp... The flange side plate 6 is re-clamped by the tool 26. The operator pulls back the rotating rod 252, causing the insertion rod 254 to separate from the flange side plate 6. The positioning mechanism 25 returns to the horizontal state. The slide table 23 feeds and re-inserts the flange side plate 6 onto the spring column 33, realizing the second clamping after flipping, and thus completing the inspection of the other end face. During this process, the connection holes of the first clamping and the second clamping are changed, which allows the blind area connection holes in the first inspection to be calibrated in the second inspection. Moreover, there is no need for manual alignment by feel. Even if there is visual obstruction, the connection hole position can be quickly adjusted and changed, which greatly reduces the difficulty of operation.

[0068] Example 3: A method for detecting plastic spools, using the detection device for plastic spools as described above, includes the following steps: S1. After the flange side plate 6 comes off the injection molding line, it is transported to the base 1. The flange side plate 6 is placed on the top of the turntable 24 and the angle is adjusted. After the adjustment is completed, the electric lifting platform 21 drives the slide 23, the turntable 24 and the flange side plate 6 to move up as a whole until the center hole of the flange side plate 6 is opposite to the center column 34. Then the slide 23 slides on the top of the electric lifting platform 21, causing the flange side plate 6 to move closer to the center column 34. Two of the connecting holes of the flange side plate 6 are connected to the two spring columns 33, and the conical surface of the center column 34 is at the center hole of the flange side plate 6. The drive mechanism 32 drives the center column 34 and the connecting ring 35 to rotate, and the two spring columns 33 rotate around, causing the flange side plate 6 to rotate as a whole.

[0069] S2. During the rotation of the flange side plate 6, the first detection component 4 and the second detection component 5 cooperate to detect the flatness of the center position and the outer ring position of the flange side plate 6 respectively.

[0070] The more specific steps of S2 are as follows: S21. Before the flange side plate 6 is moved into place and rotated, the end of the outer circle displacement sensor 53 is in contact with the outer wall of the flange side plate 6, and the end of the end face displacement sensor 52 is in contact with the outer edge of the end of the flange side plate 6.

[0071] S22. Then, the second swing arm 43 is swung so that the second swing arm 43 forms a 90-degree angle with the first swing arm 42. Then, the angle between the first swing arm 42 and the second swing arm 43 is locked by the locking member 44. At this time, the industrial camera 45 and the center displacement sensor 46 are set towards the flange side plate 6.

[0072] S23. Then, the flange side plate 6 starts to rotate. The end face displacement sensor 52 and the outer circle displacement sensor 53 respectively detect the position of the outer edge of the flange side plate 6 and the flatness of the outer wall of the flange side plate 6. The center displacement sensor 46 detects the flatness of the center position of the flange side plate 6. At the same time, the industrial camera 45 continuously takes pictures of the connection hole at the end of the flange side plate 6. By detecting the data of different positions of the flange side plate 6 from all directions, the pass rate of the flange side plate 6 can be determined.

[0073] S3. After the flange side plate 6 is inspected, the flange side plate 6 is picked up and transferred using the conveying assembly 2. With the help of the staff, the flange side plate 6 is rotated 180 degrees and reconnected with the two spring columns 33. Then, the blind spot position of the flange side plate 6 during the first inspection is re-inspected. After all the inspections are completed, the staff will remove the flange side plate 6 from the line and re-inspect the new flange side plate 6.

[0074] The more specific steps for S3 are as follows: After the inspection of flange side plate 6 is completed, the staff pushes the slide table 23 to slide on top of the bracket 22 and the electric lifting platform 21, causing the turntable 24 to move below flange side plate 6. Then, the turntable 24 is raised by the electric lifting platform 21, causing the pneumatic clamp 26 to lift and clamp flange side plate 6.

[0075] S32. Then, the worker swings the hinge plate 251 to a vertical position and pushes the rotating rod 252 toward the flange side plate 6, causing the locking rod 258 to be inserted into the arc groove 257. At the same time, the insertion rod 254 is connected to the spring column 33. The end of the spring column 33 is inserted using the second tapered part 256. After that, the spring column 33 is pushed back, causing the insertion rod 254 to be inserted into the corresponding connection hole. That is, the flange side plate 6 is obtained by the two insertion rods 254.

[0076] S33. Afterwards, the slide table 23 retracts as a whole. The operator rotates the rotating rod 252, causing the rotating plate 253 to rotate at a preset angle in conjunction with the two insert rods 254. This switches the positions of the other two connecting holes at the end of the flange side plate 6 to correspond with the two spring pillars 33. Then, the pneumatic clamp 26 clamps and positions the flange side plate 6. Subsequently, the operator retracts the two insert rods 254 from the flange side plate 6 using the rotating rod 252 and restores the hinge plate 251 to a horizontal state. Then, the operator rotates the flange side plate 6 180 degrees. Then, using the electric lifting platform 21, the slide table 23, the turntable 24, and the pneumatic clamp 26, the flange side plate 6 is driven to move upward and move closer to the two spring pillars 33. The two spring pillars 33 reconnect with the two connecting holes at the end of the flange side plate 6 after the switch. At this time, the first detection component 4 and the second detection component 5 are used to further detect the blind area of ​​the flange side plate 6. After the detection is completed, the operator can remove and replace the flange side plate 6.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
