Description

Technical Field

[0001] This utility model belongs to the technical field of rod testing equipment, specifically relating to an automatic rod hardness screening machine. Background Technology

[0002] Rod stiffness refers to the hardness of the rod material itself, i.e., its resistance to deformation. In the production of fishing rods and arrow rods, the stiffness of the rod directly affects the quality of subsequent products, making it essential to test and screen for qualified rods. Common methods for testing the material itself include using a hardness tester: pressing the rod surface with a hardness tester (such as a Shore hardness tester) to measure the material's resistance to pressure; or a three-point bending test: fixing both ends of the rod and applying pressure in the middle, recording the force required for deformation; the greater the force, the higher the material's stiffness. However, currently, rod stiffness testing is mostly done manually without dedicated equipment, resulting in low efficiency. During fishing rod production, it's necessary to locate the stiffest part of the rod (commonly known as the "rib") to facilitate the subsequent arrangement of guide rings along the rib. Currently, the location of the "rib" is mostly found manually by workers when installing the guide rings, which is inefficient and sometimes leads to errors in rib location. Utility Model Content

[0003] The purpose of this invention is to provide an automatic rod hardness screening machine, which can detect the hardness of the rod body, determine the location of the ribs, and screen and classify the rods according to their hardness values, thereby improving the efficiency of fishing rod processing.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] An automatic rod hardness sorting machine includes a rod conveying device, a detection device, and a sorting and receiving mechanism. The rod conveying device receives and conveys rods to the detection device and the sorting and receiving mechanism. The detection device includes a weight assembly mechanism, a rod rotation mechanism, and a laser displacement detection mechanism. The rod rotation mechanism supports and rotates the rods. The weight assembly mechanism suspends weights onto the rods. The laser displacement detection mechanism detects the linear displacement of the rods placed on the rod rotation mechanism in the direction perpendicular to the axis. The sorting and receiving mechanism sorts and receives rods of different hardness.

[0006] A marking mechanism is provided on one side of the rod rotation mechanism. The marking mechanism includes a marker pen, a pen holder supporting the marker pen, and a pen holder cylinder that drives the pen holder to move.

[0007] The rod conveying device includes a shift plate with a guide V-groove, a first cylinder for controlling the up and down movement of the shift plate, and a transport slide for controlling the back and forth movement of the shift plate. The telescopic rod of the first cylinder is connected to the shift plate, and the first cylinder is connected to the slide base of the transport slide.

[0008] The shifting plate has two sets that are symmetrically distributed and move in mirror image, and there are two sets of guide V-grooves on the shifting plate.

[0009] The transport slide is connected to the transport slide fixing plate. The left and right transport slide fixing plates move in a mirror image under the drive of the first synchronous belt. The transport slide is connected to the first slider via a connecting plate, and the first slider moves along the guide rail.

[0010] A temporary storage V-groove plate is provided on the front side of the rod conveying device, and a discharge guide plate is provided between the rod rotating mechanism and the sorting and receiving mechanism. The temporary storage V-groove plate, discharge guide plate and displacement plate on the left and right sides move synchronously in a mirror image.

[0011] The temporary storage V-groove plate and the unloading guide plate on the left are connected to the left transport slide fixing plate, and the temporary storage V-groove plate and the unloading guide plate on the right are connected to the right transport slide fixing plate.

[0012] The rod rotation mechanism includes two sets of support rotation devices arranged on the left and right sides of the weight assembly mechanism. Each support rotation device includes a lower support wheel and a pressure wheel. The lower support wheel supports the rod to be tested, and the rotating pressure wheel drives the rod to rotate. The two sets of support rotation devices are symmetrically distributed and move in mirror image.

[0013] The weight assembly mechanism includes weights and a weight guide groove. The weights are placed in the weight guide groove, which can move up and down under the drive of cylinder A and can move back and forth under the drive of cylinder B.

[0014] The weight is equipped with a weight hook at the upper end, and a bearing wheel is installed on the weight hook.

[0015] The sorting and receiving mechanism includes n feeding bins (n≥2), with the top of each feeding bin inclined. The first n-1 feeding bins are each equipped with an inclined receiving guide plate, which is raised and lowered by a receiving cylinder.

[0016] The beneficial effects of this invention are as follows: the rod conveying device automatically transports the received rods to the testing device; the rod rotation mechanism supports the rod; the weight assembly mechanism suspends weights onto the rod; the laser displacement detection mechanism detects the position of the rod without weights and with weights, obtaining the linear displacement perpendicular to the axis; based on the linear displacement, the deflection of the rod after suspending weights is determined, thereby determining the rod's hardness. By rotating the rod through the rod rotation mechanism, the hardness of different positions on the rod is measured, and the location of the ribs is determined; the sorting and receiving mechanism classifies and collects the rods. This invention can automatically screen rods by hardness and complete the rib identification process, improving the efficiency of fishing rod processing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0030] See Figure 1 and Figure 2 An automatic rod hardness sorting machine includes a rod conveying device 2, a detection device 3, and a sorting and receiving mechanism 5. The rod conveying device 2 receives and conveys rods to the detection device 3 and the sorting and receiving mechanism 5. The detection device 3 includes a weight assembly mechanism 31, a rod rotation mechanism 32, and a laser displacement detection mechanism 33. The rod rotation mechanism 32 supports the rod and rotates it. The weight assembly mechanism 31 suspends weights 311 on the rod. The laser displacement detection mechanism 33 detects the linear displacement of the rod placed on the rod rotation mechanism 32 in the direction perpendicular to the axis. Based on the linear displacement, the deflection of the rod after suspending weights 311 is determined. A smaller deflection value indicates a higher rod hardness, and a larger deflection value indicates a lower rod hardness. The sorting and receiving mechanism 5 receives and sorts rods of different hardness.

[0031] The rod conveying device 2 receives the rods conveyed by the feeding device 1. The feeding device 1 is a prior art structure, as described in CN119413573A, and will not be elaborated upon here. See also Figure 2 , Figure 3 and Figure 4A temporary storage V-groove plate 6 is provided on the front side of the rod conveying device 2. The rods conveyed by the feeding device 1 are temporarily stored at the temporary storage V-groove plate 6, waiting to be transported by the rod conveying device 2. The rod conveying device 2 includes two sets of shift plates 21 with guide V-grooves, a first cylinder 22 for controlling the up and down movement of the shift plates 21, and a transport slide 23 for controlling the back and forth movement of the shift plates 21. The extension rod of the first cylinder 22 is connected to the shift plate 21, and the first cylinder 22 is connected to the slide seat of the transport slide 23. The transport slide 23 is connected to the transport slide fixing plate 24. The left and right transport slide fixing plates 24 move in a mirror image under the drive of the first synchronous belt 26, thereby causing the two sets of shift plates 21 to move in a mirror image. The transport slide 23 is connected to the first slider 27 via the connecting plate 25, and the first slider 27 moves along the guide rail 8. Each shifting plate 21 has two sets of guide V-grooves. The guide V-grooves at the near end remove the rod body from the temporary storage V-groove plate 6, and the guide V-grooves at the far end remove the rod body located at the rod body rotation mechanism 32. This allows the rod body that has been inspected on the rod body rotation mechanism 32 to be transferred to the sorting and receiving mechanism 5 while feeding the rod body rotation mechanism 32.

[0032] A discharge guide plate 7 is provided between the rod rotation mechanism 32 and the sorting and receiving mechanism 5. The temporary storage V-groove plate 6 and the discharge guide plate 7 on the left are connected to the left transport slide fixed plate 24, and the temporary storage V-groove plate 6 and the discharge guide plate 7 on the right are connected to the right transport slide fixed plate 24. The left and right transport slide fixed plates 24 move in a mirror image under the drive of the first synchronous belt 26, so that the temporary storage V-groove plates 6 and the discharge guide plate 7 on both sides move synchronously in a mirror image. The temporary storage V-groove plate 6, the discharge guide plate 7 and the shifting plate 21 move synchronously in the left and right directions to accommodate the detection of rods of different specifications.

[0033] See Figure 2 , Figure 3 , Figure 6 and Figure 7The rod rotation mechanism 32 includes two sets of support rotation devices 321 arranged on the left and right sides of the weight assembly mechanism 31. Each support rotation device 321 includes a lower support wheel 3211 and a pressure wheel 3212. The lower support wheel 3211 supports the rod to be tested, and the rotating pressure wheel 3212 drives the rod to rotate. The pressure wheel 3212 is driven to rotate by a servo motor 322, which is connected to a lifting cylinder 323. The lifting cylinder 323 can adjust the vertical position of the pressure wheel 3212 to make it contact or separate from the rod being tested. When the servo motor 322 is working, it drives the pressure wheel 3212 to rotate, thereby causing the rod to rotate. The rod rotation angle can be set according to testing needs. For example, when performing hardness screening, the hardness at 0°, 90°, 180°, and 270° can be tested. The hardness values, maximum differences, minimum differences, and extreme differences at different positions of the rod can be analyzed to comprehensively evaluate the rod performance. During the rib-finding operation, the rod body is rotated more than 360° at fixed intervals to perform hardness testing (e.g., rotating 800° with 2.5° intervals). Each angle corresponds to a hardness value, and the point with the highest hardness value is the rib. Two sets of supporting rotation devices 321 are symmetrically distributed and move in mirror image to accommodate rods of different lengths. The brackets for the lower support wheel 3211 and the support lifting cylinder 323 are both mounted on the rotating fixture base plate 324. A second slider 325 is provided at the lower end of the rotating fixture base plate 324. Driven by the second synchronous belt 326, the second slider 325 moves along the slide rail.

[0034] See Figure 7 The rod rotating mechanism 32 has a marking mechanism 4 on one side. The marking mechanism 4 includes a marker pen 41, a pen holder 42 supporting the marker pen 41, and a pen holder cylinder 43 that drives the pen holder 42 to move. The detection device 3 determines the position of the rib, the pen holder cylinder 43 drives the pen holder 42 to move towards the rod, and the marker pen 41 marks the position of the rib, which is convenient for direct confirmation of the rib position in subsequent processes.

[0035] See Figure 5 The weight assembly mechanism 31 includes a weight 311 and a weight guide groove 314. The weight 311 is placed in the weight guide groove 314. The weight guide groove 314 can move up and down under the drive of cylinder A 315 and can move back and forth under the drive of cylinder B 316. By moving the weight guide groove 314 through cylinders A 315 and B 316, the weight 311 can be suspended on the rod or separated from the rod. The upper end of the weight 311 is provided with a weight hook 312, and a bearing wheel 313 is provided on the weight hook 312. The weight 311 is suspended on the rod by the weight hook 312. The bearing wheel 313 and the rod have rolling friction, which has low resistance and facilitates the suspension and movement of the weight 311.

[0036] See Figure 8The laser displacement detection mechanism 33 includes a laser displacement sensor 331 that can move up, down, left, and right. In this embodiment, the laser displacement sensor 331 is connected to a movable slide A332, and the movable slide A332 is connected to a movable slide B333 via an adapter plate 334. The movable slide A332 drives the laser displacement sensor 331 to move up and down, and the movable slide B333 drives the movable slide A332 to move back and forth, thereby realizing the up, down, left, and right movement of the laser displacement sensor 331, so as to adjust the laser displacement sensor 331 to align with the detection point according to the position of the pole.

[0037] See Figure 9 The sorting and receiving mechanism 5 includes n feeding bins 51 (where n≥2). The top of each feeding bin 51 is inclined, and the first n-1 feeding bins 51 are each equipped with an inclined receiving guide plate 52. The receiving guide plate 52 is raised and lowered by a receiving cylinder 53. The number of feeding bins 51 is set according to actual needs. For example, if the rod body needs to be divided into 5 categories based on the measured hardness value, then 5 feeding bins 51 are set. The first 4 feeding bins 51 are equipped with receiving guide plates 52. When the first receiving guide plate 52 is raised, the rod body falls into the first feeding bin 51, and so on. When all 4 receiving guide plates 52 are lowered, the rod body falls into the 5th feeding bin 51. The sorting and receiving mechanism 5 can classify the rod body, making it easier to select rod bodies of different hardness according to the needs of fishing rod processing in subsequent processing.

[0038] This utility model has a reasonable structural design, which can realize the screening of rod body hardness and the accurate positioning of rod body ribs, providing convenience for the production and processing of fishing rods, arrow shafts and other rod bodies.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
