Description

Technical Field

[0001] The present invention relates to the technical field of fishing rod detection, and in particular to a gantry type fishing rod straightness detection device and method. Background Art

[0002] A fishing rod is a fishing tool that is shaped like a long, thin, multi-section rod. It usually has a handle, and gradually becomes thinner and sharper from the handle to the rear end. It is used with a fishing line connected to a fish hook with bait.

[0003] Fishing rods need to undergo strict testing during the production process to ensure the tonality and fishing weight of the fishing rods, and to prevent the fish from being unhooked after catching a big fish. In the process of testing fishing rods, the straightness test of the fishing rod is a very important test item.

[0004] For example, the Chinese patent with publication number CN116697936A discloses a gantry type fishing rod straightness detection device and method based on machine vision, wherein the gantry type fishing rod straightness detection device based on machine vision at least includes: a central processing device, a gantry loading and unloading device, a camera device, a fishing rod clamping device, a reference marking device, a light source device and an anti-shake device for eliminating fishing rod shaking; the central processing device communicates with the gantry loading and unloading device, the camera device, the fishing rod clamping device, the reference marking device, the light source device and the anti-shake device respectively. By using a machine to replace the human eye to measure and judge the straightness of the fishing rod, it has the advantages of high precision and high efficiency.

[0005] However, the above fishing rod straightness detection device still has some shortcomings in actual use:

[0006] 1. First, in the above-mentioned prior art, the two ends of the fishing rod are horizontally limited by two fishing rod clamping devices, and the fishing rod as a whole is a conical structure with a slender top. Therefore, the middle part of the fishing rod will collapse downward due to the gravity of the fishing rod itself, making the fishing rod an arc structure, thereby affecting the accuracy of subsequent straightness detection of the fishing rod.

[0007] 2. Secondly, the prior art gantry-type fishing rod straightness detection device and method based on machine vision can achieve high-precision straightness detection of fishing rods by using machines instead of human eyes to measure and judge the straightness of fishing rods. However, after the fishing rod is detected, machine vision cannot quickly present the detected structure in a visual way, which may eventually lead to a decrease in the accuracy of fishing rod detection.

[0008] 3. Then, during the straightness test of the fishing rod, the length of the fishing rod varies, and the taper of the fishing rod is also different. However, the existing testing equipment has a certain singleness and cannot test fishing rods of different tapers and lengths. In addition, the tip section of some fishing rods is a solid structure, while the tip section of some fishing rods is a hollow structure.

DETAILED DESCRIPTION

[0051] The following is combined with Figure 1-Figure 12 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0052] The embodiment of the present application discloses a gantry-type fishing rod straightness detection device and method, which explains that the gantry-type fishing rod straightness detection device is mainly used in the batch performance detection process of fishing rod A after production. In terms of technical effect, it can prevent the middle section of fishing rod A from collapsing downward due to the gravity of fishing rod A itself, making fishing rod A into an arc structure, thereby affecting the accuracy of subsequent straightness detection of fishing rod A.

[0053] In particular, the prior art can detect the straightness of the fishing rod A with high precision by using a machine instead of the human eye to measure and judge the straightness of the fishing rod A. However, after the detection of the fishing rod A, the machine vision cannot quickly present the detected structure in a simple and clear manner, which may eventually lead to a decrease in the accuracy of the detection of the fishing rod A. Furthermore, during the straightness detection of the fishing rod A, the length of the fishing rod A varies, and the taper of the fishing rod A is also different. The existing detection equipment has a certain singleness and cannot detect fishing rods A with different tapers and lengths. In addition, the tip section of some fishing rods A is a solid structure, while the tip section of some fishing rods A is a hollow structure, which increases the difficulty of detection.

[0054] Embodiment 1:

[0055] Reference Figure 1 and Figure 2 As shown, a gantry type fishing rod straightness detection device includes a gantry frame 1, which is a liftable device for detecting fishing rods A of different lengths.

[0056] The gantry 1 is of a C-shaped structure, and a ladder is provided at its upper end for operators to go up and down. The upper end of the gantry 1 can perform up and down lifting operations, so as to ensure that the gantry 1 can place and detect fishing rods A of different lengths by means of inverted suspension, further improving the applicability of the entire device.

[0057] The inverted suspension fixer 2 is arranged on the gantry 1. The inverted suspension fixer 2 includes an insertion cylinder 20 for inserting and fixing the handle section of the fishing rod A and a clamping portion 21 for clamping the handle section of the fishing rod A. The insertion cylinders 20 are arranged at equal intervals on the inner side of the gantry 1, and the clamping portion 21 is arranged on the insertion cylinder 20.

[0058] In the prior art, the fishing rod A is usually detected in a horizontal manner. However, the body of the fishing rod A is of a conical structure. Therefore, one end of the fishing rod A is thick and the other end is thin. After it is horizontally placed, the thinner part will sag downward due to its own weight, resulting in the fishing rod A still bending after being horizontally clamped by the clamping device in the prior art. Therefore, when detecting its straightness, due to the weight of the body, the detection result will be incorrect, thus affecting the straightness detection of the fishing rod A.

[0059] Look again Figure 1 and Figure 2 As shown, it is a schematic structural diagram between the annular linkage guide rail 22 and the clamping portion 21; an annular linkage guide rail 22 for linkage opening and closing of the clamping portion 21 is also arranged at the upper end of the insertion cylinder 20; one side of the annular linkage guide rail 22 protrudes upward, and the upper end of the pressing column 215 abuts against the bottom of the annular linkage guide rail 22.

[0060] The annular linkage guide rail 22 mainly cooperates with the clamping portion 21 on the insertion cylinder 20. A protrusion is arranged on one side of the annular linkage guide rail 22, which is the position where the handle section of the fishing rod A is connected to the insertion cylinder 20; after the handle section of the fishing rod A is inserted into the insertion cylinder 20, the annular linkage guide rail 22 limits and fixes the fishing rod A through the clamping portion 21 to ensure that the fishing rod A and the insertion cylinder 20 are concentrically distributed.

[0061] A display detector 3 for straightness detection of the hollow rod tip section is arranged in cooperation with the inside of the insertion cylinder 20 and directly below the insertion cylinder 20, and a linkage laser detector 4 for detecting the fishing rod A with a solid rod tip section is also arranged on the outside of the gantry 1.

[0062] The display detector 3 mainly uses optical instruments to detect the straightness of the fishing rod A, and determines the straightness of the object surface by sensing the light reflection situation on the object surface.

[0063] The linkage laser detector 4 mainly uses the principle of laser irradiation. By irradiating the inner diameter hole of the fishing rod A with laser, it observes whether the laser can penetrate the entire fishing rod A, so as to judge whether the straightness of the fishing rod A is qualified.

[0064] Reference Figure 3 As shown, that is, a schematic diagram of the structure of batch detection of fishing rods A in this embodiment; specifically, a driving component 5 for controlling the intermittent movement of the plug-in tube 20 is provided on the gantry 1, and the driving component 5 includes a driving wheel 50, a cross 51, a driving belt 52 and a driving motor 53. The driving wheel 50 is arranged at the bottom of the cross 51, and the driving wheel 50 is distributed in a rectangular shape. The cross 51 is installed on the gantry 1, and the driving belt 52 is sleeved on a plurality of driving wheels 50. The plug-in tubes 20 are arranged at equal intervals at the bottom of the driving belt 52, and the plug-in tubes 20 are distributed vertically downward, and the driving motor 53 is arranged on the cross 51 through a motor seat, and the output shaft of the driving motor 53 is connected to the driving wheel 50 on one side.

[0065] It should be noted that the plug-in tubes 20 are installed on the side walls of the driving belt 52 at equal intervals, and when the driving belt 52 rotates, the plug-in tubes 20 can be driven to rotate synchronously.

[0066] The driving motor 53 is a known structure. The driving motor 53 is a servo motor that can control the start and stop of the driving wheel 50 and control the driving wheel 50 to rotate intermittently at equal intervals.

[0067] The gantry 1 is set on the ground and fixed. When the preparation work is completed, the handle section of the fishing rod A is inserted into the plug-in tube 20 at the bottom of the driving belt 52. At this time, the driving motor 53 is started, and the driving motor 53 drives the driving wheel 50 to rotate. Then the driving motor 53 controls the movement of the driving belt 52 through the driving wheel 50.

[0068] When the driving belt 52 is rotating, the fishing rod A placed on the driving belt 52 into the plug-in tube 20 will be clamped by the clamping part 21, ensuring that the fishing rod A can be clamped in the plug-in tube 20 and the fishing rod A is vertically downward. After the fishing rod A is fixed, the fishing rod front stopper at the upper end of the handle section of the fishing rod A is removed, so that the other fishing rod A sections that are contracted in the handle section of the fishing rod A can be extended downward, ensuring that the fishing rod A is naturally vertical.

[0069] Reference Figure 4 , Figure 5 and Figure 6As shown, that is, a schematic diagram of the structure of the fishing rod A in this embodiment when it is placed in the plug-in tube 20 to be clamped; specifically, the clamping part 21 includes a main clamping member 210, an arc-shaped clamping plate 211, an auxiliary clamping member 212, a triangular block 213, a reset compression spring 214, a pressing column 215, a pressing tension spring 216 and a synchronization component 217, the main clamping member 210 is symmetrically hinged on the plug-in tube 20, and one end of the main clamping member 210 is hinged with an arc-shaped clamping plate 211 to clamp the handle section of the fishing rod A, the other end of the main clamping member 210 is hinged to the auxiliary clamping member 212, the auxiliary clamping member 212 is slidably penetrated into the middle part of the plug-in tube 20, the triangular block 213 is installed at one end of the auxiliary clamping member 212 away from the main clamping member 210, and the auxiliary clamping member 212 is sleeved with a reset compression spring 214.

[0070] It should be noted that the main clamping member 210 is hingedly mounted on the plug-in tube 20 and can rotate. The main clamping member 210 is also hingedly provided with an arc-shaped clamping plate 211 at one end close to the fishing rod A. The arc-shaped clamping plate 211 is covered with a layer of harder rubber layer. Its main purpose is to prevent the handle section of the fishing rod A from being worn during the clamping process, and to prevent the rubber layer from being deformed after the fishing rod A is clamped due to its soft material, thereby affecting the position of the fishing rod A.

[0071] The pressing column 215 slides through the driving belt 52 and the plug-in tube 20 , and the lower end of the pressing column 215 rests on the inclined surface of the triangular block 213 . A pressing tension spring 216 is sleeved between the pressing column 215 and the plug-in tube 20 , and the synchronization component 217 is arranged between the two symmetrical triangular blocks 213 .

[0072] In the initial state, the operator needs to install the fishing rod A at the specified position, that is, directly below the raised part of the annular linkage guide rail 22. When the plug-in tube 20 is rotated to directly below the raised part of the annular linkage guide rail 22, the handle section of the fishing rod A can be inserted into the plug-in tube 20.

[0073] See also Figure 6 and Figure 7 As shown, there is a structural schematic diagram of the plug-in tube 20; an integrated cross plate is provided in the middle of the plug-in tube 20, the purpose of which is to ensure that after the operator inserts the handle section of the fishing rod A into the interior of the plug-in tube 20, the handle section of the fishing rod A can directly rest against the cross plate, thereby ensuring the quick installation of the fishing rod A.

[0074] During the specific implementation process, after the operator inserts the handle section of the fishing rod A into the plug-in tube 20, the driving motor 53 drives the driving belt 52 to move at a uniform and slow speed. During this process, the pressing column 215 on the driving belt 52 will continue to rotate. At this time, continue to hold the fishing rod A. After the pressing column 215 moves to the raised part away from the annular linkage guide rail 22 and enters the horizontal area of ​​the annular linkage guide rail 22, the pressing column 215 will be squeezed by the annular linkage guide rail 22, so that the pressing column 215 squeezes the two symmetrically distributed triangular blocks 213, and then the triangular blocks 213 push the secondary clamping member 212 outward, and then the secondary clamping member 212 squeezes one end of the main clamping member 210. At this time, the main clamping member 210 rotates around the hinge point, so that the arc-shaped clamping plate 211 on the main clamping member 210 is simultaneously against the handle section of the fishing rod A, thereby clamping the fishing rod A.

[0075] The clamping portion 21 in the present invention can not only clamp the fishing rod A, but also, with the cooperation of the synchronization component 217, can ensure that the fishing rod A and the plug-in tube 20 are concentrically distributed. The purpose is to ensure that the laser of the subsequent linked laser detector 4 can accurately penetrate into the interior of the fishing rod A after emission to detect the straightness of the fishing rod A, thereby avoiding the impact of external factors on the detection of the straightness of the fishing rod A.

[0076] In addition, the inverted hanging method of the fishing rod A can prevent the fishing rod A from bending due to its own weight when the fishing rod A is placed horizontally, thereby affecting the straightness detection of the fishing rod A.

[0077] After the fishing rod A is clamped by the clamping part 21, the above operation is repeated to ensure that the fishing rod A can be inserted into the plurality of plug-in tubes 20 on the driving belt 52, so as to realize batch fixing of the fishing rod A. After the fishing rod A is fixed, the display detector 3 arranged on one side of the gantry 1 starts to detect the straightness of the intermittently moving fishing rod A, as shown below:

[0078] See also Figure 8 As shown, the display detector 3 includes a vertical frame 30, a light emitter 31, a fixing seat 32 and a light receiving curtain wall 33. The vertical frame 30 is arranged inside the gantry 1 and is vertically downwardly distributed in the middle of the driving belt 52. The light emitter 31 is arranged on the side wall of the gantry 1 through the fixing seat 32, and is slidingly distributed between the fixing seat 32 and the gantry 1. The light receiving curtain wall 33 is arranged on the vertical frame 30 and is used to receive the light emitted by the light emitter 31. After receiving the light, the light receiving curtain wall 33 can change color.

[0079] In the initial state, the light emitter 31 is arranged on the vertical frame 30 , and the vertical frame 30 is slidably arranged at the vertical end of the gantry 1 to ensure that the light emitter 31 can move horizontally.

[0080] It should be noted that the light emitter 31 is an existing known structure, and the light emitter 31 can emit a large amount of ultraviolet rays, and the ultraviolet rays it generates can cover the entire fishing rod A within the ultraviolet area.

[0081] When the ultraviolet rays irradiate the fishing rod A, they will continue to irradiate the light receiving curtain wall 33, and the light receiving curtain wall 33 is made of sensitive material. When the ultraviolet rays irradiate the light receiving curtain wall 33, the light receiving curtain wall 33 quickly changes color. The light receiving curtain wall 33 is arranged on the back side of the fishing rod A. The ultraviolet rays cannot irradiate the area blocked by the fishing rod A, so that obvious illuminated areas and non-illuminated areas will appear on the light receiving curtain wall 33. At this time, the straightness of the fishing rod A can be detected by taking pictures and comparing the area where the illuminated area and the non-illuminated area intersect.

[0082] After the light emitter 31 stops ultraviolet irradiation, the light receiving curtain wall 33 can quickly return to the same color as the non-illuminated area after a short time. Not only will it not affect the subsequent batch inspection of fishing rods A, but it can also improve the efficiency and accuracy of the straightness inspection of fishing rods A.

[0083] Secondly, it should be noted that the tip section of the fishing rod A has two structures, solid material and hollow material. Therefore, in order to improve the adaptability of the present invention, when the fishing rod A is hollow material, the straightness of the fishing rod A can be detected in two different ways through the display detector 3 and the linked laser detector 4; when the fishing rod A is solid material, the straightness of the fishing rod A can be detected through the display detector 3, thereby greatly improving the applicability of the detection of the fishing rod A.

[0084] The display detector 3 in the present invention can display the external illumination shadow of the fishing rod A through the cooperation of the light receiving curtain wall 33. It can not only observe with the naked eye whether the fishing rod A is in a straight state, but also judge by visual inspection if the fishing rod A is bent or twisted; and observe the interactive reflection of the fishing rod A and the light to judge the straightness of the fishing rod A. The light will produce different brightness reflections on its surface and be directly projected onto the light receiving curtain wall 33, thereby improving the accuracy of its detection.

[0085] See also Fig. 9 and Fig.10 As shown, the linked laser detector 4 includes a laser emitter 40, a linkage component 41 and a laser receiving curtain wall 42. The laser emitter 40 is arranged inside the plug-in tube 20, and one end of the laser emitter 40 that emits laser is vertically distributed downward, and the laser emitter 40 is concentrically distributed with the plug-in tube 20. The linkage component 41 is arranged on the laser emitter 40, and the laser receiving curtain wall 42 is arranged at the bottom of the gantry 1, and the laser receiving curtain wall 42 and the laser emitter 40 are on the same straight line.

[0086] It should be noted that the laser emitter 40 is arranged inside the plug-in tube 20, and the laser emitter 40 is concentrically distributed with the plug-in tube 20. The purpose is to facilitate the clamping of the fishing rod A in the plug-in tube 20 and ensure that the laser emitted by the laser emitter 40 can be consistent with the fishing rod A.

[0087] After the laser transmitter 40 emits the laser downward, the laser will pass through the handle section of the fishing rod A and other sections of the fishing rod A, and finally pass through the tip section of the fishing rod A and hit the laser receiving curtain wall 42. If the laser point can be detected on the laser receiving curtain wall 42, it means that the straightness of the entire fishing rod A is within the compliance range; if the laser point is not detected on the laser receiving curtain wall 42, it means that the fishing rod A itself is bent.

[0088] The laser transmitter 40 is a known structure. However, if the laser transmitter 40 continues to emit laser downward for a long time, a large amount of electric energy will be wasted. In the prior art, the laser transmitter 40 is controlled to switch on and off, which makes it impossible to accurately grasp the time of excitation and emission. Therefore, the present invention proposes a linkage component 41 to ensure that the laser transmitter 40 is turned on at a suitable time and place to detect the straightness of the fishing rod A during the rotation of the fishing rod A along the driving belt 52. Specifically:

[0089] See also Fig.10 As shown, the linkage component 41 includes two symmetrically distributed metal sensing sheets 410 and a wire 411 connected to the metal sensing sheets 410. The wire 411 is arranged between the metal sensing sheets 410 and the laser transmitter 40 to supply power to the laser transmitter 40. The two metal sensing sheets 410 are arranged in the plug-in tube 20, and the metal sensing sheets 410 on one side are slidably distributed up and down.

[0090] The slidingly distributed metal sensing sheet 410 is in contact with an insulating column 412, which slides through the plug-in tube 20 and extends upward. The gantry 1 is provided with a No. 2 guide rail 413 that cooperates with the insulating column 412, and a linkage compression spring 414 is connected between the insulating column 412 and the plug-in tube 20. A sliding groove is provided on the annular linkage guide rail 22 for the insulating column 412 to rise and fall, and a circular hole is provided on the pressing column 215 for the insulating column 412 to slide, so as to avoid interference between the pressing column 215 and the insulating column 412.

[0091] It should be noted that, in the initial state, the No. 2 guide rail 413 is arranged above the annular linkage guide rail 22, the insulating column 412 is against the bottom of the No. 2 guide rail 413, and a sliding groove is provided on the annular linkage guide rail 22 for the insulating column 412 to slide, so as to avoid interference between the clamping of the fishing rod A and the detection of the fishing rod A.

[0092] During the specific implementation process, after the fishing rod A is clamped, the fishing rod A will move synchronously along the rotation direction of the driving belt 52. When the insulating column 412 on the driving belt 52 moves to the recessed position of the No. 2 guide rail 413, the recessed area of ​​the No. 2 guide rail 413 will squeeze the insulating column 412. At this time, the insulating column 412 presses down on the movable metal sensing sheet 410, so that the movable metal sensing sheet 410 contacts with the fixed metal sensing sheet 410, thereby ensuring that the entire broken circuit of the wire 411 becomes a passage. At this time, it can ensure that the laser transmitter 40 can be powered on to emit laser.

[0093] When fishing rod A completes the detection, fishing rod A will continue to rotate following the driving belt 52. During this process, the pressed down insulating column 412 will leave the recessed position of the No. 2 guide rail 413. At this time, the insulating column 412 moves upward to the initial state under the action of the linkage compression spring 414, and the movable metal sensor sheet 410 also moves upward, so that the entire laser transmitter 40 changes from a passage to a circuit breaker again, thereby cutting off the power of the laser transmitter 40.

[0094] It can not only realize intermittent operation of the laser transmitter 40, reduce power consumption, and achieve cost control, but also prevent the laser transmitter 40 from causing irreversible damage to the eyes of operators working nearby due to long-term operation.

[0095] Similarly, when the linkage component 41 can control the laser emitter 40, but is not limited to this, the linkage component 41 can control the laser emitter 40 to emit laser to reduce its cost consumption, avoid the laser emitter 40 from wasting energy at will, and increase its service life. The linkage component 41 can also be linked with the light emitter 31 to control the irradiation time and timing of ultraviolet rays in the light emitter 31.

[0096] Embodiment 2: Based on Embodiment 1, in order to further improve the accuracy of the straightness detection of the fishing rod A in this embodiment, the present invention further proposes a synchronization component 217.

[0097] When the pressing column 215 squeezes the clamping portion 21, the two triangular blocks 213 may be worn due to the long-term reciprocating contact between the pressing column 215 and the triangular blocks 213, thereby affecting the displacement distance of the two triangular blocks 213 and causing the two triangular blocks 213 to be unable to move synchronously relative to each other. Therefore, the present invention also proposes a synchronization component 217.

[0098] See also Figure 6 and Figure 7As shown, the synchronization component 217 is arranged between the two triangular blocks 213 to ensure that one or both of the two triangular blocks 213 can always move synchronously relative to each other after being squeezed by the pressing column 215; specifically, the synchronization component 217 is used to control the two main clamping members 210 to perform synchronous relative movement, and the synchronization component 217 includes a synchronization gear 2170 rotatably arranged inside the plug-in cylinder 20 and a synchronization rack 2171 installed on the triangular block 213 and controlling the synchronous movement of the triangular block 213. The synchronization gear 2170 and the synchronization rack 2171 are meshed with each other, and the synchronization rack 2171 is staggered and arranged on the triangular block 213.

[0099] One end of the synchronization rack 2171 is connected to the triangular block 213, and the other end is engaged with the synchronization rack 2171. When the triangular block 213 on one side is squeezed and moved outward by the pressing column 215, the synchronization rack 2171 connected thereto moves synchronously, and in the process drives the synchronization gear 2170 to rotate. At this time, the other synchronization rack 2171 engaged with the synchronization gear 2170 will move synchronously in the opposite direction accordingly, thereby realizing the synchronous movement of the two triangular blocks 213, further ensuring that the fishing rod A can be quickly and accurately distributed concentrically with the plug-in tube 20 during the clamping process.

[0100] See also Fig.11 As shown, a lifting bracket 60 is provided on the gantry 1, and the lifting bracket 60 is provided with a driving wheel 50, a cross 51 and a driving belt 52 which are the same as those on the driving component 5, and the driving belt 52 on the lifting bracket 60 is provided with an anti-shake clamp 61 distributed corresponding to the plug-in tube 20, and a synchronization shaft 62 is connected between the driving wheel 50 on the lifting bracket 60 and the driving wheel 50 on the gantry 1.

[0101] The lifting bracket 60 can move up and down to cope with fishing rods A of different lengths. When the fishing rod A is tilted downward, the tip section of the fishing rod A is thin and prone to shaking. Therefore, when the fishing rod A is tilted downward, the tip section at its upper end can be restricted in the anti-shake clamp 61 on the lifting bracket 60 to prevent the tip section of the fishing rod A from shaking. At the same time, it can also protect the tip section and prevent it from breaking during the straightness detection process.

[0102] See also Fig.12 As shown, in addition, the present invention also provides a gantry type fishing rod straightness detection method, the gantry type fishing rod straightness detection method is as follows:

[0103] S1. Fishing rod preparation: transport the fishing rod A to be tested to the testing area and place the fishing rod A at the designated location. The operator then goes down the escalator on the gantry 1 and adjusts the height of the gantry 1 according to the fishing rod A to be tested.

[0104] S2. Fixing the fishing rod: remove the rear plug on the handle section of the fishing rod A to be tested, install it into the plug-in tube 20 at the bottom of the gantry 1 in an inverted manner, and clamp and fix it through the arc-shaped clamping plate 211 to ensure that the center of the circle of the fishing rod A and the center of the circle of the plug-in tube 20 are on the same straight line. The purpose is to facilitate the subsequent straightness test of the fishing rod A. Then remove the front plug of the fishing rod A, extend the other sections of the fishing rod A downward, and ensure that the fishing rod A is in a naturally drooping state.

[0105] S3. Fishing rod external detection: After the fishing rod A is fixed, ultraviolet rays are emitted through the display detector 3, and after the ultraviolet rays are irradiated to the fishing rod A, the ultraviolet rays continue to irradiate the light receiving curtain wall 33. After the ultraviolet rays are irradiated to the light receiving curtain wall 33, the light receiving curtain wall 33 quickly changes color. The light receiving curtain wall 33 is arranged on the back side of the fishing rod A. The ultraviolet rays cannot irradiate the area blocked by the fishing rod A. Therefore, obvious illuminated areas and non-illuminated areas will appear on the light receiving curtain wall 33. At this time, the straightness of the fishing rod A can be detected by taking pictures and comparing the area where the illuminated area and the non-illuminated area intersect.

[0106] S4. Inspection inside the fishing rod: After the projection straightness inspection is performed on the outside of the fishing rod A, the linked laser detector 4 projects laser light inside the fishing rod A to check the straightness of the fishing rod A again and see if the fishing rod A is deformed.

[0107] It should be noted that the tip section of the fishing rod A has two structures, solid material and hollow material. Therefore, in order to improve the adaptability of the present invention, when the fishing rod A is hollow material, the straightness of the fishing rod A can be detected in two different ways through the display detector 3 and the linked laser detector 4; when the fishing rod A is solid material, the straightness of the fishing rod A can be detected through the display detector 3, thereby greatly improving the applicability of the detection of the fishing rod A.

[0108] S5. Cyclic testing: After the fishing rod A has been tested, the straightness of the fishing rod A is tested in batches through an assembly line. The tested fishing rod A is disassembled, and the fishing rod A to be inspected is installed in the plug-in tube 20 vacated after disassembly, thereby achieving batch cyclic testing of the fishing rod A.

[0109] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
