Description

Technical Field

[0001] This invention relates to the field of saw chain production technology, and more specifically to a saw chain production line. Background Technology

[0002] The saw chain is an important component of a chainsaw. A saw chain is a special toothed chain that has the functions of transmission and cutting. A saw chain generally consists of four parts, including the cutter head, the central guide tooth, the connecting plate, and the rivet. The cutter head is divided into left and right cutter heads, and the connecting plate is divided into left and right connecting plates.

[0003] In the existing saw chain assembly process, the central guide tooth is fitted onto the rivet, and then the connecting piece and blade on one side of the central guide tooth are installed and riveted. Then, the central guide tooth is flipped over and the connecting piece and blade on the other side of the central guide tooth are installed and riveted, thus completing the saw chain assembly production.

[0004] The existing production line has the following problems when assembling and riveting saw chains:

[0005] 1. When the saw chain needs to be flipped at the beginning of assembly, it is usually flipped manually, which is time-consuming and labor-intensive and can easily cause the saw chain to be misaligned, thus affecting subsequent processing, failing to achieve automation and resulting in low production efficiency.

[0006] 2. The later improvement adopted a flipping track for flipping. However, the flipping track requires high processing precision and high smoothness of its inner surface. Therefore, if the inner surface of the flipping track is not smooth enough or is not clean, such as if there is dust or other impurities, it will cause the saw chain parts to get stuck or jammed, causing blockage in the flipping track, paralyzing the production line, making it impossible to produce normally, and seriously affecting production efficiency.

[0007] Therefore, how to automate the assembly process of saw chain production lines and improve saw chain production efficiency is a pressing technical problem that needs to be solved. Summary of the Invention

[0053] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0054] The saw chain production line of this application can be used in occasions such as assembling and producing saw chains, and of course it can also be used in other similar application scenarios. The following is a detailed description of a saw chain production line.

[0055] See appendix Figure 1 — Figure 23 The diagram shows a structural schematic of an embodiment of a saw chain production line according to this application. This saw chain production line includes a semi-riveting device 1 and a full riveting device 2. Both the semi-riveting device 1 and the full riveting device 2 are equipped with connecting mechanisms 3 for conveying semi-finished products, and the full riveting device 2 is equipped with a winding mechanism 4 for winding the saw chain. Both the semi-riveting device 1 and the full riveting device 2 include a tank chain conveying mechanism 5, a central guide tooth unloading mechanism 6, a connecting piece unloading mechanism 7, a cutter head unloading mechanism 8, and a riveting mechanism 9. The semi-riveting device 1 also includes a semi-riveting frame 10 and a semi-riveting rivet unloading mechanism 11 mounted on the semi-riveting frame 10. The full riveting device 2 also includes a full riveting frame 12 and a full riveting rivet unloading mechanism 13, a semi-riveting cutter head unloading mechanism 14, and a semi-riveting connecting piece unloading mechanism 15 mounted on the full riveting frame 12. Along the conveying direction of one of the tank chain conveying mechanisms 5, the following components are sequentially... The semi-riveting frame 10 is equipped with a semi-riveting rivet feeding mechanism 11, a middle guide tooth feeding mechanism 6, a connecting piece feeding mechanism 7, and a riveting mechanism 9. The tank chain conveying mechanism 5 is used to convey the middle guide tooth and the connecting piece. On one side of another tank chain conveying mechanism 5 in the semi-riveting device 1, along the conveying direction of the tank chain conveying mechanism 5, the semi-riveting rivet feeding mechanism 11, the middle guide tooth feeding mechanism 6, the cutter head feeding mechanism 8, and the riveting mechanism 9 are sequentially provided on the semi-riveting frame 10. The tank chain conveying mechanism 5 is used to convey the middle guide tooth and the cutter head. On one side of the tank chain conveying mechanism 5 of the full riveting device 2, along the conveying direction of the tank chain conveying mechanism 5, the full riveting rivet feeding mechanism 13, the semi-riveting cutter head feeding mechanism 14, the semi-riveting connecting piece feeding mechanism 15, the cutter head feeding mechanism 8, the connecting piece feeding mechanism 7, and the riveting mechanism 9 are sequentially provided on the full riveting frame.

[0056] This invention utilizes a semi-riveting device 1 to separately rivet the central guide tooth and connecting piece, as well as the central guide tooth and cutting head. Specifically, one central guide tooth is riveted to one connecting piece to form a connecting piece semi-riveting component, and one central guide tooth is riveted to one cutting head to form a cutting head semi-riveting component. By incorporating two tank chain conveying mechanisms 5 within the semi-riveting device 1, the connecting piece semi-riveting component and the cutting head semi-riveting component are partially riveted separately, ensuring independent conveying, preventing conveying errors, avoiding errors in subsequent production and assembly, and ensuring that the connecting piece semi-riveting component and the cutting head semi-riveting component are riveted together during subsequent riveting. The first and second riveted parts will not become disordered, ensuring normal riveting of the saw chain. The connecting mechanism 3 allows for the flipping of the connecting plate and the cutter head half-rivet parts without the need for a flipping track; instead, a horizontal track is used, reducing processing precision requirements and surface finish requirements. Even if dust or other impurities appear inside the track, it will not affect the conveying process, thus ensuring production efficiency. The winding mechanism 4 allows for the winding of the assembled saw chain, preventing it from piling up messily on the worktable after riveting, thus improving worker efficiency. The system eliminates the need for workers to spend time organizing the saw chain, preventing them from being cut by the saw blades during the process, thus reducing their workload and ensuring their safety. The guide tooth feeding mechanism 6 feeds the guide teeth, assembling them onto the rivets. The connecting piece feeding mechanism 7 feeds the connecting pieces, assembling them onto the rivets. The cutter head feeding mechanism 8 feeds the cutter head, assembling it onto the rivets. Finally, the riveting mechanism 9 rivets the saw chain. The mechanism rivets the central guide tooth to the connecting piece, the central guide tooth to the cutter head, and the saw chain. The semi-rivet cutting mechanism 11 can cut the double-headed rivets required for semi-riveting. The full-rivet cutting mechanism 13 can cut the single-headed rivets. The semi-rivet cutter head cutting mechanism 14 can cut the semi-rivet part where the central guide tooth and cutter head have been riveted, allowing the semi-rivet part to be assembled onto the single-headed rivet. The semi-rivet connecting piece cutting mechanism 15 can cut the semi-rivet part where the central guide tooth and connecting piece have been riveted.

[0057] It should be noted that the connecting piece feeding mechanism 7 and the cutter head feeding mechanism 8 in this application have the same structure, except that the vibratory feeder and the guide plate are adjusted accordingly. The specific structure of the vibratory feeder and the guide plate are all prior art and will not be described in detail here. The semi-rivet feeding mechanism 11 and the full-rivet feeding mechanism 13 in this application have the same structure. The semi-rivet feeding mechanism 11 feeds double-headed rivets, while the full-rivet feeding mechanism feeds single-headed rivets. Only the vibratory feeder and the guide plate need to be adjusted accordingly.

[0058] See appendix Figure 4 and Figure 5 As shown, in this invention, the tank chain conveying mechanism 5 includes a tank chain 51, a rodless cylinder 52 located beside the tank chain 51, a connecting top plate 53 mounted on the rodless cylinder 52, a connecting support plate 54 mounted on the connecting top plate 53, a connecting bottom plate 55 mounted on the connecting support plate 54 and connected to the rodless cylinder 52, a rotating plate 56 movably mounted on the bottom surface of the connecting top plate 53, and a limiting block 57 provided on the top surface of the connecting bottom plate 55 for limiting the rotation plate 56; wherein, transmission pins 511 are provided at equal intervals on the side of the tank chain 51, the minimum distance of the transmission pin 511 from the plane where the bottom surface of the rodless cylinder 52 is located is greater than the minimum distance from the top surface of the connecting bottom plate 55 to the plane where the bottom surface of the rodless cylinder 52 is located, and the minimum distance of the transmission pin 511 from the plane where the bottom surface of the rodless cylinder 52 is located is less than the minimum distance from the bottom surface of the connecting top plate 53 to the plane where the bottom surface of the rodless cylinder 52 is located; the tank chain 51 is also provided with placement holes 512 at equal intervals.

[0059] This invention utilizes the tank chain 51 to transmit the central guide teeth, connecting plates, and cutter heads; the rodless cylinder 52 provides the power source for the movement of the tank chain 51, enabling it to move in steps; the connecting top plate 53 provides an installation position for the rotating plate 56; the connecting support plate 54 supports the connection between the connecting bottom plate 55 and the connecting top plate 53; the rotating plate 56, when rotated, in conjunction with the transmission pin 511, enables the tank chain 51 to move in steps; the limiting block 57 ensures that the rotating plate 56 can only rotate in one direction, ensuring that the tank chain 51 can be driven to move in steps via the transmission pin 511; and the placement hole 512 is used to place rivets.

[0060] Specifically, when the rodless cylinder 52 drives the connecting top plate 53 and the connecting bottom plate 55 to move in the opposite direction to the front of the tank chain 51, the rotating plate 56 is not restricted by the limiting block 57 and can rotate until the rodless cylinder 52 moves to the designated position. Subsequently, when the rodless cylinder 52 moves in the forward direction of the tank chain 51, the rotating plate 56 is restricted by the limiting block 57 and cannot rotate, thus pushing the transmission pin 511 forward, thereby pushing the tank chain 51 forward. It should be noted that the minimum distance from the bottom surface of the connecting top plate 53 to the transmission pin 511 is greater than the width of the rotating plate 56. The width of the rotating plate 56 is the distance between two parallel planes on the rotating plate 56, and these two parallel planes are perpendicular to the moving direction of the rodless cylinder 52.

[0062] The present invention arranges the central guide teeth by setting the central guide tooth vibratory plate 61; guides the movement of the central guide teeth by setting the central guide tooth slide plate 63; provides a power source for the movement of the central guide teeth by setting the central guide tooth push cylinder 64; provides an installation position for the central guide tooth unloading cylinder 66 by setting the central guide tooth upright plate 65; and guides and transports the central guide teeth arranged and output by the central guide tooth vibratory plate 61 by setting the central guide tooth guide plate 67.

The central guide tooth slide plate 63 is also provided with a movable groove 632 that communicates with the central guide tooth groove 631.

With the ejection port 309, after the half-rivet is reversed, it can be ejected from the other side of the flip channel 306, allowing it to proceed to subsequent assembly and riveting. The half-rivet cutter head feeding cylinder 312 and the half-rivet connecting piece feeding cylinder 322 can eject the half-rivet from the ejection port 309 in the flip channel 306.

[0077] See appendix Figure 17 — Figure 19As shown, in this invention, the semi-rivet head unloading mechanism 14 includes a semi-rivet head mounting base 141 mounted on the full riveting machine frame 12, a semi-rivet head translation cylinder 142 mounted on the semi-rivet head mounting base 141, a semi-rivet head translation block 143 mounted on the semi-rivet head translation cylinder 142, a first mounting plate 144 mounted on the semi-rivet head mounting base 141, a lifting rodless cylinder 145 mounted on the first mounting plate 144, a first lifting plate 146 mounted on the lifting rodless cylinder 145, and a straightening cone column 148 mounted at the bottom of the first lifting plate 146.

[0078] The present invention provides a moving power source for the semi-rivet part of the guide tooth and the cutter head by setting a semi-rivet head translation cylinder 142, so that the semi-rivet part can be moved; by setting a semi-rivet head translation block 143, the semi-rivet part can be contacted, and the semi-rivet part can be moved and adjusted; by setting a first mounting plate 144, a mounting position is provided for a lifting rodless cylinder 145; by setting a lifting rodless cylinder 145, the first lifting plate 146 drives the straightening cone 148 to move up and down; by setting a straightening cone 148, it can be inserted into the riveting holes at both ends of the semi-rivet part to correct and adjust the position of the semi-rivet part.

[0079] See appendix Figure 17 picture- Figure 19 As shown, in this invention, the semi-rivet head mounting base 141 is provided with a semi-rivet head feeding groove 1411 connected to the semi-rivet head feeding channel 311.

[0086] See appendix Figure 1 — Figure 23 As shown, the working process of this invention is as follows:

[0087] First, the two tank chain conveying mechanisms 5 on the semi-riveting device 1, in conjunction with different mechanisms on the sides of the two tank chain conveying mechanisms 5, respectively rivet the guide teeth and connecting plates, and the guide teeth and cutting heads respectively. Specifically, the double-headed rivets are neatly arranged by the semi-riveting vibratory plate 111, and then guided by the semi-riveting guide tube 114. At the same time, the second parallel air gripper 117 is in a clamping state, and the double-headed rivets fall onto the second parallel air gripper 117. Then, the first parallel air gripper 115 clamps the next rivet. The semi-riveting rodless cylinder 116 drives the second parallel air gripper 117 to descend to the designated position. Then, the second parallel air gripper 117 is released, and the double-headed rivets fall into the placement hole 512 on the tank chain 51. Then, the second parallel air gripper 117 is reset, and the first parallel air gripper 115 is released. When the double-headed rivets fall onto the second parallel air gripper 117, the first parallel air gripper 115 clamps again, and this process is repeated.

[0088] Secondly, the center guide tooth unloading mechanism 6 places the center guide tooth onto the double-headed rivet. Specifically, the center guide tooth vibrating plate 61 guides the center guide tooth into the center guide tooth groove 631 of the center guide tooth slide plate 63 through the center guide tooth guide plate 67. Then, the center guide tooth pushing cylinder 64 drives the center guide tooth pushing block 641 to move, pushing the center guide tooth into the center guide tooth cavity 636. Subsequently, the telescopic rod of the center guide tooth unloading cylinder 66 extends, so that the center guide tooth abutment plate 662 contacts the center guide tooth. The telescopic rod continues to extend, the center guide tooth abutment spring 663 is compressed, and the guide inclined surface 665 on the center guide tooth control column 664 contacts the mating inclined surface 637, pushing the center guide tooth placement block 633 to move, compressing the center guide tooth compression spring 635, unloading the center guide tooth, and installing it onto the double-headed rivet.

[0089] Next, the connecting piece feeding mechanism 7 places the connecting piece onto the rivet, where it contacts the central guide tooth; specifically, the connecting piece vibrating plate 71 guides the connecting piece onto the first movable plate 77 via the connecting piece guide plate 75. The connecting piece is contacted by the connecting piece locking block 74 and blocked, preventing it from falling. Subsequently, the connecting piece lifting cylinder 73 moves in the oblong hole 781 via the control screw 732, causing the first movable plate 77 to move; similarly, the cutting head feeding mechanism 8 on the other tank chain conveying mechanism 5 on the semi-rivet device 1 places the cutting head onto the double-headed rivet.

[0090] Then, the riveting mechanism 9 rivets the central guide tooth and connecting piece, and the central guide tooth and the cutting head; specifically, the lifting motor 92 drives the lifting screw 93 to rotate, causing the screw nut seat 94 to descend, which in turn drives the riveting motor 96 to descend. At the same time, the riveting motor 96 drives the riveting head 97 to rotate, and it contacts the rivet to perform riveting.

[0091] Subsequently, the semi-rivet parts of the semi-rivet device 1 are conveyed and flipped through the connecting mechanism 3. Specifically, the semi-rivet parts on the tank chain conveying mechanism 5 enter the flipping channel 306 through the auxiliary material conveying channel 301, and then come into contact with the wireless sensor 308. Then the servo motor 303 rotates at equal angles until it rotates 180°. After each rotation of the servo motor 303, the corresponding feeding cylinder, namely the telescopic rod of the semi-rivet head feeding cylinder 312 or the semi-rivet connecting piece feeding cylinder 322, extends to push out the semi-rivet parts that have completed the 180° flip in the flipping channel 306 from the ejection port 309.

[0092] The full riveting device 2's full riveting rivet feeding mechanism 13 places the single-headed rivet onto the tank chain 51 of the tank chain conveying mechanism 5 in the full riveting device 2. The placement process is the same as the principle of the half riveting rivet feeding mechanism 11.

[0093] Next, the semi-rivet head unloading mechanism 14 unloads the semi-rivet part with the cutter head and the middle guide tooth, and installs the semi-rivet part onto the single-head rivet. Specifically, the semi-rivet part is conveyed to the semi-rivet head feed groove 1411 through the connecting mechanism 3 until it reaches the mating groove 1431. Then, the semi-rivet head translation cylinder 142 drives the semi-rivet head translation block 143 to push the semi-rivet part along the semi-rivet head movable groove 1412 to the designated position. The lifting rodless cylinder 145 drives the straightening cone column 148 to descend through the first lifting plate 146 and insert it into the two riveting holes of the semi-rivet part for installation and riveting.

[0094] After the semi-rivet head unloading mechanism 14 completes the unloading, the semi-rivet connecting piece unloading mechanism 15 unloads the connecting piece and the middle guide tooth semi-rivet onto the saw chain. Specifically, the semi-rivet is transported to the semi-rivet connecting piece mounting base 151 via the connecting mechanism 3. Then, the micro vacuum pump 156 starts vacuum suction. At the same time, the semi-rivet connecting piece rodless cylinder 153 drives the micro vacuum pump 156 to descend via the second lifting plate 154 until it reaches the designated position, so that the rivet is inserted into the extension tube 157. Then, the semi-rivet connecting piece rodless cylinder 153 drives the micro vacuum pump 156 to descend. The air pump 156 rises, and then the rodless cylinder 159 moves through the second movable plate 155 to drive the micro vacuum pump 156 to move, thereby driving the half-rivet connecting piece to move. The half-rivet connecting piece is limited by the groove on the connecting piece limiting plate 1571. After the second movable plate 155 moves to the designated position, the rodless cylinder 153 of the half-rivet connecting piece drives the micro vacuum pump 156 to move down to the designated position again. Then the micro vacuum pump 156 stops working, the half-rivet connecting piece is assembled, and then riveted by the riveting mechanism 9 on the full riveting device 2.

[0095] Finally, the assembled and riveted saw chain is wound up and organized by the winding mechanism 4.

[0096] It should be noted that when all mechanisms are unloading materials, the rodless cylinder 52 in the tank chain conveyor mechanism 5 is reset. At this time, the moving direction of the rodless cylinder 52 is opposite to the forward direction of the tank chain 51, and it cannot push the tank chain 51 to convey materials. In addition, the designated positions mentioned in this application are all achieved by various sensors or proximity switches and controlled by a PLC controller.

[0097] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
