Description

Technical Field

[0001] This invention belongs to the field of chain detection technology, and in particular relates to a chainsaw chain detection device. Background Technology

[0002] As the core transmission component of power cutting tools, the quality of the chainsaw chain directly affects cutting efficiency and safety. Traditional inspection methods rely heavily on manual visual inspection or random checks with simple tools, which suffers from low efficiency, poor consistency, and easy omissions, especially in critical areas such as the back of the chain, the teeth, and the connecting plates, which are difficult to inspect comprehensively.

[0003] Current automated chain inspection equipment uses image detection devices to visually inspect the chain under tension. However, its detection direction is singular, only able to acquire images of one side of the chain, which cannot meet the actual need of simultaneously inspecting both the front and back of a chainsaw chain. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a chainsaw chain detection device that can simultaneously detect both the front and back sides.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This chainsaw chain detection device includes a frame, on which a baffle is provided. The front of the baffle has a rotatable upper wheel with active teeth, and the back of the baffle has an upper wheel rotation drive assembly connected to the upper wheel. A lifting slot is formed on the baffle below the upper wheel, and a rotatable lower wheel is formed on the front of the lifting slot. The lower wheel is connected to a lower wheel lifting assembly on the back of the lifting slot. A chain is also formed on the baffle between one side of the upper and lower wheel. A back-side inspection port is provided on the back of the chain, and a back-side camera module is provided on the outside of the upper and lower wheel bodies, away from the back-side inspection port. The front-side camera module is connected to a front-side camera shifting mechanism, which can be used to move the front-side camera module away from the upper and lower wheel bodies when not in the inspection state. The front-side camera module, the front-side camera shifting mechanism, the back-side camera module, and the lower wheel body lifting assembly are electrically connected to a control circuit, and the control circuit is electrically connected to a display on the frame.

[0006] A chain tensioning and rotation mechanism is constructed by integrating upper and lower wheels with a baffle. The adjustable lower wheel accommodates different chain lengths and controls chain tension. A back-side inspection port and rear-side camera module are provided on the baffle for inspecting the back of the chain. Simultaneously, the front-side camera module is relocated from the workstation via a shifting mechanism, facilitating chain assembly, disassembly, and maintenance. The overall layout is compact, with simultaneous front and rear visual inspection. Combined with a unified control circuit and display, this achieves efficient and comprehensive automated visual inspection of chainsaw chains.

[0007] In the aforementioned chainsaw chain detection device, the front camera shifting mechanism includes a crossbar located outside the upper and lower wheel bodies. The front camera module is mounted on the crossbar, and the outer end of the crossbar is connected to a crossbar lifting linear actuator. Through the combination of the crossbar and the lifting linear actuator, the vertical positioning and relocation of the front camera module are achieved. The lifting drive allows for flexible adjustment of the camera height to ensure clear imaging; the relocation function allows the camera module to completely avoid the operating area when not in operation, facilitating chain assembly and disassembly, and improving operational safety and efficiency.

[0008] In the aforementioned chainsaw chain inspection device, a first lateral adjustment structure is provided between the crossbar and the front camera module; the front camera module is electrically connected to the control circuit via a front wire, and the front wire is connected to the crossbar via an anti-drop fixing bracket; a second lateral adjustment structure is provided between the anti-drop fixing bracket and the crossbar. By setting the first and second lateral adjustment structures, the horizontal position adjustment of the front camera module is realized, ensuring that the camera can accurately focus on the chain inspection area; at the same time, the anti-drop fixing bracket can prevent detachment failure, improve the adjustment flexibility of the equipment, and enhance its long-term reliability.

[0009] In the aforementioned chainsaw chain detection device, the first lateral adjustment structure includes a first T-shaped groove at the bottom of the crossbar, a front camera module with a front camera bracket, and at least one first T-shaped nut within the first T-shaped groove. The front camera bracket is connected to the T-shaped nut via bolts. This connection method, with the first T-shaped groove at the bottom of the crossbar and the T-shaped nut, allows the front camera module to slide flexibly along the crossbar and lock securely, achieving stepless adjustment of the camera position and ensuring the accuracy and stability of the camera module's alignment with the front of the chain during detection.

[0010] In the aforementioned chainsaw chain detection device, the second lateral adjustment structure includes a second T-shaped groove located at the top of the crossbar. At least one second T-shaped nut is located within the second T-shaped groove. The second T-shaped nut is connected to an anti-drop mounting bracket via bolts. The anti-drop mounting bracket is equipped with an adjustable clamp for securing the front-facing wire. The second T-shaped groove and nut allow for adjustable horizontal position of the anti-drop mounting bracket on the crossbar, ensuring coordination with the movement of the front-facing camera module. Simultaneously, the adjustable clamp design securely fixes the wire, preventing signal interruption or equipment malfunction due to wire swinging, sagging, or accidental detachment, thus improving system operational safety and reliability.

[0011] In the aforementioned chainsaw chain inspection device, a front supplementary lighting ring is fitted onto the front camera module. This ring is mounted on a front annular frame, which is integrated with a drop-proof mounting bracket. By integrating the front supplementary lighting ring and the camera module onto the same annular frame and fixing it to the drop-proof bracket, it ensures that the light source maintains a constant relative position with the lens during adjustment and movement. This provides stable, uniform, and shadow-free frontal illumination, improving the consistency, clarity, and defect identification accuracy of image acquisition.

[0012] In the aforementioned chainsaw chain detection device, the lower wheel lifting assembly includes a heavy-duty slider. This heavy-duty slider is connected to the frame via a slider rail unit. It is also connected to a heavy-duty slider linear actuator on one side via a transmission plate. One end of the transmission plate is fixed to the output end of the heavy-duty slider linear actuator, while the other end rests against the bottom of the heavy-duty slider or is fixed to it. The combination of the heavy-duty slider and the high-rigidity rail unit ensures that the lower wheel maintains stable and precise vertical lifting motion even under chain tension, effectively resisting lateral loads and vibrations. The transmission plate directly transmits the output of the linear actuator to the bottom of the slider, forming a stable thrust transmission path and improving the overall structural load-bearing reliability and stability.

[0013] In the aforementioned chainsaw chain detection device, the upper wheel rotation drive assembly includes a rotating shaft and an upper wheel rotation driver.

[0014] The rotating shaft is provided with a first inner abutment sleeve, and the rotating shaft is also provided with an inner wear-resistant ring, a drive wheel, an outer wear-resistant ring and a first shaft end locking nut arranged sequentially from the inside to the outside at the outer end of the first inner abutment sleeve. The radius of the inner wear-resistant ring is larger than the root circle radius of the drive wheel, and the first shaft end locking nut is screwed to the rotating shaft.

[0015] The outer end of the shaft is provided with a first keyway, the circumference of the drive wheel is provided with a drive wheel groove that cuts in radially, and the inner walls of the drive wheel on both sides of the drive wheel groove are respectively provided with inner protrusions, which are embedded in the first keyway.

[0016] Both the inner and outer wear-resistant rings have radially tangential wear-resistant grooves on their circumferences. By clamping the drive wheel between the inner and outer wear-resistant rings, and with the radius of the inner wear-resistant ring being larger than the root circle radius of the drive wheel's teeth, the service life of the drive wheel can be extended. Simultaneously, the radial grooves on the drive wheel, combined with the engagement of the inner protrusion and the keyway of the shaft, achieve reliable torque transmission and facilitate the installation and disassembly of the drive wheel, thus improving overall assembly convenience and operational stability.

[0017] In the aforementioned chainsaw chain detection device, the lower wheel body and the lower wheel body lifting assembly are connected by a driven shaft, and the driven shaft is provided with a second inner sleeve.

[0018] The lower wheel body includes an inner limiting ring, a spacer ring, and an outer limiting ring, which are arranged sequentially from the inside to the outside on the driven shaft and located at the outer end of the second inner abutment sleeve. The outer limiting ring has a second shaft end locking nut screwed to the driven shaft at its outer end. The outer diameter of the spacer ring is smaller than the outer diameters of the inner and outer limiting rings, respectively. The inner and outer limiting rings form a limiting structure on both sides of the axial direction, which can restrain the lateral movement of the chain on the driven shaft and prevent the chain from running off track or falling off. The inner limiting ring, spacer ring, and outer limiting ring adopt a split combination structure, which, together with the second inner abutment sleeve and the shaft end locking nut, provides axial locking, facilitates assembly, and allows for flexible replacement of different parts according to different types of chains, improving the overall versatility.

[0019] In the aforementioned chainsaw chain detection device, the inner and outer limiting rings are made of non-magnetic materials, while the spacer ring is made of magnetic material. The use of magnetic material for the spacer ring enables localized magnetic adsorption and positioning of the chain, preventing slippage or misalignment during detection and thus improving detection stability.

[0020] Compared with existing technologies, the advantages of this chainsaw chain inspection device are: 1. Dual camera module layout, simultaneous defect identification on both sides of the chain, resulting in excellent inspection performance. 2. Removable camera modules for easy chain assembly and disassembly. 3. Flexible adjustment to accommodate chainsaw chains of different lengths and specifications. 4. Precise positioning, ensuring stable and secure chain contact without slippage during inspection. Attached Figure Description

Detailed Implementation

[0036] like Figures 1 to 14As shown, this chainsaw chain detection device includes a frame 1, on which a baffle 11 is provided. The front of the baffle 11 has a rotatable upper wheel 21 with active teeth. The back of the baffle 11 has an upper wheel rotation drive assembly 2 connected to the upper wheel 21. A lifting slot 111 is provided on the baffle 11 below the upper wheel 21. A rotatable lower wheel 31 is provided on the front of the lifting slot 111, and the lower wheel 31 is connected to the lower wheel lifting assembly 3 on the back of the lifting slot 111. A chain back detection port 112 is also provided on the baffle 11 between one side of the upper wheel 21 and the lower wheel 31. A rear camera module 4 is provided on the back of the detection port 112 on the back of the chain. A front camera module 5 is provided on the outside of the upper wheel body 21 and the lower wheel body 31, on the side away from the rear detection port 112. The front camera module 5 is connected to the front camera shifting mechanism 12. The front camera shifting mechanism 12 can be used to move the front camera module 5 away from the upper wheel body 21 and the lower wheel body 31 when it is not in the detection state. The front camera module 5, the front camera shifting mechanism 12, the rear camera module 4 and the lower wheel body lifting assembly 3 are electrically connected to the control circuit 6. The control circuit 6 is electrically connected to the display 61 on the frame 1.

[0037] In this embodiment, the chainsaw chain 7 is mounted between the upper wheel 21 and the lower wheel 31. The lower wheel 31 is driven by the lower wheel lifting assembly 3 to descend along the lifting groove 111 to tension the chainsaw chain 7. The upper wheel rotation drive assembly 2 drives the upper wheel 21 to rotate, pulling the chainsaw chain 7 to rotate synchronously. During this process, the front camera module 5, which is moved to the workstation, and the back camera module 4, which is fixed to the back of the baffle 11, are located in front of the left side and behind the right side of the chain. The back camera module 4 collects images of the inside of the chainsaw chain 7 through the detection port 112 on the back of the chain, effectively avoiding optical interference. The collected image signals are transmitted to the control circuit 6 for defect identification and analysis, and the results are displayed in real time on the display 61. After the detection is completed, the front camera module 5 is moved away by the shifting mechanism 12, and the lower wheel 31 rises and resets, completing the detection cycle. This achieves the excellent effect of accurately detecting defects on both sides of the chainsaw chain 7.

[0038] In this embodiment, the rear camera module 4 and the front camera module 5 may include high frame rate industrial cameras, which are illuminated by the rear fill light ring 42 and the front fill light ring 52. The captured images are transmitted to the control circuit 6 for defect identification. The control circuit 6 for defect identification and the method for defect identification are existing technologies.

[0039] More specifically, the front camera shifting mechanism 12 includes a crossbar 121 located outside the upper wheel body 21 and the lower wheel body 31. The crossbar 121 is equipped with a front camera module 5, and the outer end of the crossbar 121 is connected to the crossbar lifting linear drive 13.

[0040] In this embodiment, the horizontal bar lifting linear actuator 13 includes a lifting motor, and the horizontal bar lifting linear actuator 13 is provided with a slider that can be lifted and lowered along the slide rail under the drive of the lifting motor. The outer end of the horizontal bar 121 is connected to the slider.

[0041] like Figure 2 and 3 As shown, a first lateral adjustment structure 122 is provided between the crossbar 121 and the front camera module 5; the front camera module 5 is electrically connected to the control circuit 6 through the front wire 62, and the front wire 62 is connected to the crossbar 121 through the anti-fall fixing bracket 125, and a second lateral adjustment structure 126 is provided between the anti-fall fixing bracket 125 and the crossbar 121.

[0042] In this embodiment, the front guide wire 62 passes through the baffle 11 and is located on the side of the upper wheel 21 away from the front camera shifting mechanism 12.

[0043] like Figure 7 As shown, the first lateral adjustment structure 122 includes a first T-shaped groove 123 at the bottom of the crossbar 121, a front camera bracket 51 on the front camera module 5, a first T-shaped nut 124 in the first T-shaped groove 123, and the front camera bracket 51 is connected to the T-shaped nut 124 by bolts.

[0044] More specifically, the second lateral adjustment structure 126 includes a second T-shaped groove 127 set at the top of the crossbar 121, a second T-shaped nut 128 in the second T-shaped groove 127, the second T-shaped nut 128 being connected to the anti-fall fixing frame 125 by bolts, and the anti-fall fixing frame 125 being provided with an adjustable clamp 621 for fixing the front guide wire 62.

[0045] More specifically, a front fill light ring 52 is fitted on the front camera module 5, and the front fill light ring 52 is set on the front ring frame 53. The front ring frame 53 is integrated with the anti-fall fixing frame 125.

[0046] like Figure 4 and 5 As shown, the lower wheel lifting assembly 3 includes a heavy-duty slider 32, which is connected to the frame 1 via a slider rail unit 33. The heavy-duty slider 32 is connected to a heavy-duty slider linear actuator 34 on one side via a transmission plate 341. One end of the transmission plate 341 is fixed to the output end of the heavy-duty slider linear actuator 34, and the other end abuts against the bottom of the heavy-duty slider 32. A counterweight frame 35 is also provided at the bottom of the heavy-duty slider 32.

[0047] In this embodiment, the heavy-duty slider linear actuator 34 includes a linear telescopic cylinder. The output end of the linear telescopic cylinder is connected to one end of the upper surface of the transmission plate 341, and the other end of the upper surface of the transmission plate 341 abuts against the bottom of the heavy-duty slider 32. The slider rail unit 33 includes a heavy-duty lifting rail disposed on the back of the baffle 11 and arranged parallel to the lifting strip groove 111. The heavy-duty slider 32 is disposed on the heavy-duty lifting rail.

[0048] The rear camera module 4 is connected to the frame 1 via an inverted L-shaped bracket 41. The rear camera module 4 is fixed on the lower end of the L-shaped bracket 41. A rear fill light ring 42 is sleeved around the rear camera module 4. The rear fill light ring 42 is connected to the lower end of the L-shaped bracket 41 via a rear ring frame 43.

[0049] like Figures 9 to 11 As shown, the upper wheel rotation drive assembly 2 includes a rotating shaft 22 and an upper wheel rotation driver 23;

[0050] The rotating shaft 22 is provided with a first inner abutment sleeve 221. The rotating shaft 22 is also provided with an inner wear-resistant ring 212, a drive wheel 211, an outer wear-resistant ring 213 and a first shaft end locking nut 222, which are distributed from the inside to the outside at the outer end of the first inner abutment sleeve 221. The radius of the inner wear-resistant ring 212 is larger than the root circle radius of the drive wheel 211. The first shaft end locking nut 222 is screwed to the rotating shaft 22.

[0051] A first keyway 223 is provided on the outer end of the rotating shaft 22, and a radially incised drive wheel groove 214 is provided on the circumference of the drive wheel 211. An inner protrusion 215 is provided on the inner wall of the drive wheel 211 on both sides of the drive wheel groove 214, and the inner protrusion 215 is embedded in the first keyway 223.

[0052] Both the inner wear ring 212 and the outer wear ring 213 have radially incised wear ring grooves 216 on their circumference.

[0053] In this embodiment, the drive wheel groove 214 and the wear-resistant ring groove 216 penetrate the annular wall thickness of the drive wheel 211 and the inner wear-resistant ring 212 and the outer wear-resistant ring 213, respectively, so that they form a non-closed open ring structure.

[0054] In this embodiment, the drive wheel 211 has several evenly distributed grooves 217 on its circumference that can cooperate with the teeth of the chainsaw chain 7;

[0055] like Figures 12 to 14 As shown, the lower wheel body 31 is connected to the lower wheel body lifting assembly 3 via a driven shaft 36, and a second inner sleeve 361 is provided on the driven shaft 36;

[0056] The lower wheel body 31 includes an inner limiting ring 312, a spacer ring 311, and an outer limiting ring 313 arranged sequentially from the inside to the outside on the driven shaft 36 and located at the outer end of the second inner abutment sleeve 361. The outer end of the outer limiting ring 313 is provided with a second shaft end locking nut 362 that is screwed to the driven shaft 36. The outer diameter of the spacer ring 311 is smaller than the outer diameters of the inner limiting ring 312 and the outer limiting ring 313, respectively.

[0057] In this embodiment, a radially incised spacer groove 314 is provided on the circumference of the spacer ring 311, and a radially incised limit ring groove 315 is provided on the circumference of both the inner limit ring 312 and the outer limit ring 313.

[0058] More specifically, the inner limiting ring 312 and the outer limiting ring 313 are made of non-magnetic materials, while the spacer ring 311 is made of magnetic materials.

[0059] In this embodiment, the first shaft end locking nut 222 and the second shaft end locking nut 362 are provided with radial locking screws, or the first shaft end locking nut 222 and the second shaft end locking nut 362 are expansion nuts.

[0060] In this embodiment, the upper wheel body rotation drive assembly 2 includes an upper wheel body rotation driver 23. The upper wheel body rotation driver 23 is fixed on the frame 1 by an upper wheel body rotation driver bracket. The upper wheel body rotation driver 23 is detachably connected to the upper wheel body 21 by a rotating shaft 22.

[0061] The lower wheel body 31 is connected to the lower wheel body lifting assembly 3 via the driven shaft 36, and the lower wheel body 31 and the driven shaft 36 are detachably connected.

[0062] In this embodiment, the upper wheel body rotation driver 23 includes a rotary motor, which drives the upper wheel body 21 to rotate by driving the rotating shaft 22 to rotate.

[0063] The working principle of this embodiment is as follows: the operator hangs the chainsaw chain 7 on the drive wheel 211 of the upper wheel body 21 and the spacer ring 311 of the lower wheel body 31. Subsequently, the lower wheel body lifting assembly 3 is activated, and the heavy-duty slider linear drive 34 pushes the heavy-duty slider 32 through the transmission plate 341, causing it to move smoothly downward along the slider slide rail unit 33, thereby driving the lower wheel body 31 connected to the heavy-duty slider 32 to move downward along the lifting strip groove 111 on the baffle 11, thus achieving tensioning of the chainsaw chain 7. During this process, since the spacer ring 311 is made of magnetic material, it can generate a local magnetic attraction force on the chainsaw chain 7, assisting in its rapid positioning and preventing slippage; at the same time, the inner limit ring 312 and the outer limit ring 313 form a limit on both sides of the axial direction, constraining the lateral movement of the chainsaw chain 7 and preventing it from deviating or falling off.

[0064] After the chainsaw chain 7 is tensioned, the upper wheel rotation drive assembly 2 starts working. The upper wheel rotation driver 23 drives the shaft 22 to rotate, which engages with the inner protrusion 215 on the drive wheel 211 through the first keyway 223, causing the drive wheel 211 to rotate at a constant speed. The tooth groove 217 on the drive wheel 211 meshes with the teeth of the chainsaw chain 7, pulling each link of the chainsaw chain 7 sequentially and accurately through the preset detection area.

[0065] As the chainsaw chain 7 moves, the front camera shifting mechanism 12 is activated, and the crossbar lifting linear actuator 13 drives the crossbar 121 to descend, sending the front camera module 5 and the front supplementary lighting ring 52 mounted on it to the preset detection station. The front camera module 5 continuously acquires images of the outer side (front) of the chainsaw chain 7. At the same time, the back camera module 4, fixed to the back of the baffle 11, synchronously acquires images of the inner side (back) of the chainsaw chain 7 through the chain back detection port 112. The two camera modules are located on both sides of the chain, and the back supplementary lighting ring 42 and the front supplementary lighting ring 52 provide stable illumination respectively.

[0066] Image signals acquired by the front camera module 5 and the rear camera module 4 are transmitted in real time to the control circuit 6 via the front conductor 62 and other lines. The image processing algorithm built into the control circuit 6 analyzes the images and automatically identifies defects such as missing links, deformation, or assembly errors. The real-time status, parameters, and final defect identification results of the entire detection process are all displayed synchronously on the display 61 on the rack 1.

[0067] After the entire chainsaw chain 7 has been inspected, the system enters the reset process. The front camera shifting mechanism 12 activates first, with the horizontal bar lifting linear actuator 13 driving the horizontal bar 121 upwards, moving the front camera module 5 away from the working area to make room for operation. Next, the lower wheel lifting assembly 3 drives the lower wheel 31 upwards, restoring the chainsaw chain 7 to a slack state, allowing the operator to easily remove it, thus completing one full automated inspection cycle.
