Description

Technical Field

[0001] This invention relates to the field of guide rail cage assembly technology, specifically to an industrial robot for automatic pressing of linear guide rail cage tongues. Background Technology

[0002] The linear guide cage assembly is a key component for achieving smooth movement of the linear guide. The cage assembly consists of a metal cage and multiple rollers. The rollers are assembled into corresponding retaining holes on the cage. The cage has two metal tongues to keep the rollers from falling out. Depending on different requirements, the cage assembly has different lengths. When installing the rollers, the 90-degree tongue of the cage must be bent to 45 degrees to fix the rollers. Therefore, it takes a long time to install a single cage assembly.

[0003] For example, in the linear guide rail cage tongue automatic pressing device disclosed in patent CN217618910U, the cage material strip with assembled rollers is conveyed to the compensation pressing mechanism by an automatic conveying device during operation. A secondary pressing cylinder drives the pressing block to descend, and through pressing protrusions, performs secondary compensation pressing of the rollers in the retaining holes of all cages to ensure the accuracy of the roller assembly position. When the cage material strip passes the detection device, the detection cylinder drives the detection block to descend, and a contact detection probe detects whether rollers are assembled in the retaining holes. The cage material strip is then conveyed to the first... When the tongue pressing mechanism and the second tongue pressing mechanism are in operation, the first pressing cylinder and the second pressing cylinder drive the first pressing plate and the second pressing plate to move respectively. The tongue is automatically pressed by the first pressing protrusion and the second pressing protrusion. However, in the above technical solution, the pressing of the tongue on the roller side requires two pressing cylinders to drive independently. If the actions of the two pressing cylinders are not synchronized, it will cause uneven force on the cage material belt and cause deviation, which will affect the assembly quality. Moreover, the secondary pressing of the cage, the tongue pressing, the fixed length cutting and the intermittent conveying are controlled by different actuators, and the linkage between the various structures in the device is not strong. Summary of the Invention

[0004] The purpose of this invention is to provide an industrial robot for automatically pressing together the tongue of a linear guide cage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an industrial robot for automatic pressing of linear guide rail retainer tongues, comprising a housing and a synchronous pressing assembly. The synchronous pressing assembly is disposed at opposite ends inside the housing. The synchronous pressing assembly includes a base fixedly installed at both ends inside the housing. Guide bars are fixedly installed on both sides of the base, and sliders are slidably installed on the guide bars. Pressing protrusions are alternately installed on the inner opposing surfaces of the sliders on both sides. An inclined groove is formed in the middle of the slider. A trigger block is correspondingly disposed on the inclined groove, and the conical surface of the inner wall of the inclined groove abuts against the outer shape of the trigger block. The trigger block is fixedly installed at both ends of the bottom of the transition plate.

[0006] Furthermore, a conveyor frame is fixedly installed in the middle of the machine housing, and a cutting seat is installed at the end of the conveyor frame. A material feeding guide is connected to the side of the cutting seat away from the end of the conveyor frame.

[0007] Furthermore, the upper limit of the conveyor frame is provided with a retainer belt, and the retainer belt has positioning holes at equal intervals along its length.

[0008] Furthermore, the retainer belt has pockets spaced at equal intervals in the middle, and rollers facing opposite directions are installed alternately inside the pockets.

[0009] Furthermore, a metal tongue is installed on the side end of the pocket opening, and the metal tongue bends under the pressure of the corresponding side pressing protrusion, thereby achieving the limiting and retention of the roller.

[0010] Furthermore, a cylinder is bolted to the top of the housing, and a top plate is fixedly connected to the telescopic end of the cylinder. Guide rods are fixedly connected to the top of both sides of the top plate, and the guide rods are matched with guide sleeves at corresponding positions on the housing.

[0011] Furthermore, a cutter is fixedly installed at the bottom front end of the top plate, and the cutter cooperates with the cutting seat at the end of the conveyor frame to achieve fixed-length cutting of the retainer strip. A spring is connected around the bottom of the top plate, and the spring is elastically connected to the transition plate at one end away from the top plate.

[0012] Furthermore, the rear end of the top plate is connected to a lifting linkage assembly, which includes an "L"-shaped gear rod fixedly connected to the rear end of the top plate. The outer tooth profile of the gear rod meshes with the outer circle tooth profile of the gear, and a one-way bearing is installed inside the bushing coaxial with the gear. The gear is rotatably mounted on the bracket through the one-way bearing, and the root of the bracket is welded and fixed to the bottom end of the housing.

[0013] Furthermore, the lifting linkage assembly also includes a conveyor wheel rotatably mounted on the other side of the bracket. The conveyor wheel is connected to the gear through a one-way bearing to form a one-way rotational transmission. The outer circle array of the conveyor wheel is fixed with guide pins, and the guide pins are engaged with the positioning holes on the side end of the retainer material belt.

[0014] Furthermore, a secondary pressing assembly is elastically connected to the bottom end of the transition plate. The secondary pressing assembly includes a base plate disposed below the transition plate. Two springs are connected to the top two sides of the base plate, and the elastic coefficient of the second spring is lower than that of the first spring. A connecting column is elastically connected to the end of the second spring away from the base plate, and the connecting column is fixedly installed at both ends of the bottom of the transition plate. Sponge blocks are installed at equal intervals at the bottom of the base plate corresponding to the roller positions on the retaining frame material belt, and pressure sensors are embedded inside the sponge blocks.

[0015] This invention provides an industrial robot for automatically pressing together linear guide cage tongues, which has the following beneficial effects;

[0016] 1. In use, this application utilizes the cooperation of the secondary pressing component and the synchronous pressing component. By taking advantage of the fact that the elastic coefficient of spring two is lower than that of spring one, spring two is compressed first when the cylinder moves downward, driving the sponge block to complete the secondary pressing of the roller first. This ensures that the roller is fully embedded in the pocket and avoids the problem of incomplete initial pre-assembly. After spring two is compressed to the correct position, spring one is compressed again to trigger the tongue pressing action. This step-by-step logic of first fixing the internal parts and then locking the external structure ensures the assembly quality from the action sequence and reduces the problem of tongue pressing failure caused by the roller not being in place.

[0017] 2. In use, during the final stage of the cylinder's force application, the cutter at the front end of the top plate cooperates with the cutting seat connected to the end of the conveyor frame to cut the finished cage after the metal tongue is pressed. This application integrates three processes—secondary pressing, tongue pressing, and fixed-length cutting—in the cylinder's downward stroke. During the cylinder's lifting and resetting stroke, the conveyor wheel is driven by the linkage between the rack and the gear with a one-way bearing to achieve intermittent conveying of the cage material belt. Multiple processes are coordinated through the same power source, and the assembly efficiency is effectively improved by optimizing the linkage between various structural components.

[0018] 3. When this application is in use, the cylinder is activated and the bottom plate is driven to descend sequentially through the top plate and the transition plate. Because the elastic coefficient of the second spring connected to the transition plate on the bottom plate is lower than that of the first spring connected to the top plate on the transition plate, the second spring will be compressed before the first spring, causing the sponge block under the bottom plate to be pressed down to the position of the roller on the retainer belt. The deformable characteristics of the sponge block itself not only allow it to fit with the different rollers that are staggered and facing opposite directions to achieve secondary pressing, thereby ensuring that the rollers on the retainer belt are correctly inserted into the corresponding pockets, but also the pressure sensor embedded inside the sponge block can identify the defect of missing rollers in real time through pressure feedback, making up for the problem of blind spot in visual inspection caused by the metal tongue blocking the rollers.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Please see Figures 5 to 7The present invention provides a technical solution: an industrial robot for automatic pressing of linear guide rail retainer tongue, including a housing 1 and a synchronous pressing assembly 2. The synchronous pressing assembly 2 is arranged at opposite ends inside the housing 1. The synchronous pressing assembly 2 includes a base 201 fixedly installed at both ends inside the housing 1. Guide bars 202 are fixedly installed on both sides of the base 201, and sliders 203 are slidably installed on the guide bars 202. Pressing protrusions 204 are alternately installed on the inner opposite surfaces of the sliders 203. An inclined groove 205 is opened in the middle of the slider 203. A trigger block 206 is correspondingly arranged on the inclined groove 205. The conical surface of the inner wall of the inclined groove 205 abuts against the outer shape of the trigger block 206. The trigger block 206 is fixedly installed at both ends of the bottom of the transition plate 207.

[0030] The specific operation is as follows: As the cylinder 11 extends and retracts, the spring 15 is compressed, causing the trigger blocks 206 on both sides of the transition plate 207 to be inserted into the middle inclined groove 205 of the adjacent side slider 203. Through the abutment between the conical surface of the inner wall of the inclined groove 205 and the outer shape of the trigger block 206, the two sliders 203 slide on the guide bar 202 to achieve mutual closing. The pressing protrusions 204 on the inner opposite surfaces of the two sliders 203 are staggered and correspond to the metal tongues 10 on the side of the rollers 9 that are spaced apart on the retainer belt 6. During the synchronous and equal application of force to the two sliders 203, the metal tongues 10 on the side of the rollers 9 are simultaneously bent to achieve... To limit and retain the roller 9, this application uses the cooperation of the secondary pressing assembly 17 and the synchronous pressing assembly 2. By taking advantage of the fact that the elastic coefficient of spring 2 1702 is lower than that of spring 15, when the cylinder 11 moves downward, spring 2 1702 is compressed first, driving the sponge block 1704 to complete the secondary pressing of the roller 9 first. This ensures that the roller 9 is fully embedded in the pocket 8 and avoids the problem of initial pre-installation not being in place. After spring 2 1702 is compressed to the right position, spring 15 is compressed again to trigger the tongue pressing action. This step-by-step logic of first fixing the internal parts and then locking the external structure ensures the assembly quality from the action sequence and reduces the problem of tongue pressing failure caused by the roller 9 not being in place.

[0031] Please see Figures 1 to 8A conveyor frame 3 is fixedly installed in the middle of the housing 1, and a cutting seat 4 is installed at the end of the conveyor frame 3. A feeding guide 5 is connected to the side of the cutting seat 4 away from the end of the conveyor frame 3. A retainer belt 6 is conveyed at the upper limit above the conveyor frame 3. Positioning holes 7 are evenly spaced along the length of the side of the retainer belt 6. Pockets 8 are evenly spaced in the middle of the retainer belt 6. Rollers 9 facing opposite directions are installed alternately inside the pockets 8. A metal tongue 10 is installed on the opening side of the pocket 8. The metal tongue 10 is bent under the pressure of the corresponding side pressing protrusion 204 to limit and retain the rollers 9. Transition plate 20 7. A secondary pressing component 17 is elastically connected to the bottom end. The secondary pressing component 17 includes a bottom plate 1701 set below the transition plate 207. Springs 1702 are connected to the top two sides of the bottom plate 1701. The elastic coefficient of springs 1702 is lower than that of springs 15. A connecting post 1703 is elastically connected to the end of springs 1702 away from the bottom plate 1701. The connecting post 1703 is fixedly installed at both ends of the bottom of the transition plate 207. Sponge blocks 1704 are installed at equal intervals at the positions of rollers 9 on the retainer belt 6 at the bottom of the bottom of the bottom plate 1701. A pressure sensor 1705 is embedded inside the sponge block 1704.

[0032] The specific operation is as follows: the cylinder 11 is activated and the bottom plate 1701 is driven to descend through the top plate 12 and the transition plate 207 in sequence. Because the elastic coefficient of the second spring 1702 connected to the transition plate 207 above the bottom plate 1701 is lower than that of the first spring 15 connected to the top plate 12 above the transition plate 207, the second spring 1702 will be compressed before the first spring 15, and the sponge block 1704 under the bottom plate 1701 will be pressed down to the position of the roller 9 on the retainer material belt 6. The deformable characteristics of the sponge block 1704 itself can not only make it fit with the different rollers 9 that are staggered and facing opposite directions to achieve secondary pressing, thereby ensuring that the rollers 9 on the retainer material belt 6 are correctly implanted into the corresponding pockets 8, but also the pressure sensor 1705 embedded inside the sponge block 1704 can identify the defect of missing rollers 9 in real time through pressure feedback, making up for the visual inspection blind spot caused by the metal tongue 10 blocking the rollers 9.

[0033] Please see Figures 3 to 6A cylinder 11 is bolted to the top of the housing 1, and a top plate 12 is fixedly connected to the telescopic end of the cylinder 11. Guide rods 13 are fixedly connected to the top of both sides of the top plate 12, and the guide rods 13 are limited by guide sleeves at corresponding positions on the housing 1. A cutter 14 is fixedly installed at the bottom front end of the top plate 12, and the cutter 14 cooperates with the cutting seat 4 at the end of the conveyor frame 3 to cut the material belt 6 of the retainer to a fixed length. Springs 15 are connected around the bottom of the top plate 12, and the end of the springs 15 facing away from the top plate 12 is elastically connected to the transition plate 207. A lifting linkage assembly 16 is driven to the rear end of the top plate 12. The lifting linkage assembly 16 includes an "L"-shaped toothed rod 160 fixedly connected to the rear end of the top plate 12. 1. The outer tooth profile of the rack 1601 meshes with the outer tooth profile of the gear 1602, and a one-way bearing 1603 is installed inside the bushing coaxial with the gear 1602. The gear 1602 is rotatably mounted on the bracket 1604 through the one-way bearing 1603, and the root of the bracket 1604 is welded and fixed to the bottom of the housing 1. The lifting linkage assembly 16 also includes a conveyor wheel 1605 rotatably mounted on the other side of the bracket 1604. The conveyor wheel 1605 forms a one-way rotational transmission connection with the gear 1602 through the one-way bearing 1603, and a guide pin 1606 is fixed on the outer circle array of the conveyor wheel 1605. The guide pin 1606 is engaged with the positioning hole 7 on the side end of the retainer material belt 6.

[0034] The specific operation is as follows: During the final stage of force application by cylinder 11, the cutter 14 at the front end of top plate 12 cooperates with the cutting seat 4 connected to the end of conveyor frame 3 to cut the finished retainer after the metal tongue 10 is pressed. After all the secondary pressing, tongue pressing, and fixed-length cutting processes of the current retainer are completed, cylinder 11 pulls top plate 12, transition plate 207 and bottom plate 1701 in reverse order to lift. At this time, the rack 1601 at the rear end of top plate 12 meshes with gear 1602 on one side of bracket 1604. Gear 1602 then rotates through one-way bearing 1603 to the conveyor wheel 1605 on the other side of bracket 1604. The one-way bearing 1603 allows gear 1602 to idle and cut during the downward stroke of cylinder 11, while the rotation of conveyor wheel 1605 is also affected. During the reverse lifting stroke, a transmission connection is established between gear 1602 and conveyor wheel 1605. Then, through the snap-fit ​​engagement between the outer guide pin 1606 of conveyor wheel 1605 and the positioning hole 7 at the side end of the cage material belt 6, the intermittent conveying of the cage material belt 6 is achieved during the reset stroke of cylinder 11. The previously processed cage is pushed out of the end of conveyor frame 3 and automatically cut off in the next stroke. This application integrates three processes in the downward pressing stroke of cylinder 11: secondary pressing, tongue pressing, and fixed-length cutting. During the lifting and reset stroke of cylinder 11, the gear 1602 with a one-way bearing 1603 is linked to drive conveyor wheel 1605 to achieve intermittent conveying of cage material belt 6. Multiple processes are coordinated through the same power source, and the assembly efficiency is effectively improved by optimizing the linkage between various structural components.

[0035] In summary, when using this linear guide cage tongue automatic pressing industrial robot:

[0036] First, the cylinder 11 is activated and the bottom plate 1701 is lowered sequentially through the top plate 12 and the transition plate 207. Because the elastic coefficient of the second spring 1702 connected to the transition plate 207 above the bottom plate 1701 is lower than that of the first spring 15 connected to the top plate 12 above the transition plate 207, the second spring 1702 will be compressed before the first spring 15, causing the sponge block 1704 under the bottom plate 1701 to be pressed down at the position of the roller 9 on the retainer material belt 6. The deformable characteristics of the sponge block 1704 not only allow it to fit with the different rollers 9 that are staggered and facing opposite directions to achieve secondary pressing, thereby ensuring that the rollers 9 on the retainer material belt 6 are correctly inserted into the corresponding pockets 8, but also the pressure sensor 1705 embedded inside the sponge block 1704 can identify the defect of missing rollers 9 in real time through pressure feedback, making up for the visual inspection blind spot caused by the metal tongue 10 blocking the rollers 9.

[0037] Secondly, as the cylinder 11 extends and retracts, the spring 15 is compressed, causing the trigger blocks 206 on both sides of the transition plate 207 to insert into the middle inclined groove 205 of the adjacent side slider 203. Through the abutment between the conical surface of the inner wall of the inclined groove 205 and the outer shape of the trigger block 206, the two sliders 203 slide on the guide bar 202 to achieve mutual closing. The pressing protrusions 204 on the inner opposite surfaces of the two sliders 203 are staggered and correspond to the metal tongues 10 on the side of the rollers 9 that are spaced apart on the retainer belt 6. During the synchronous and equal application of force to the two sliders 203, the metal tongues 10 on the side of the rollers 9 are simultaneously bent to achieve mutual rolling. To maintain the position of roller 9, this application utilizes the cooperation of the secondary pressing assembly 17 and the synchronous pressing assembly 2. By taking advantage of the fact that the elastic coefficient of spring 2 1702 is lower than that of spring 15, the cylinder 11 compresses spring 2 1702 first when it moves downward, driving the sponge block 1704 to complete the secondary pressing of roller 9 first. This ensures that roller 9 is fully embedded in pocket 8, avoiding the problem of initial pre-installation not being in place. After spring 2 1702 is compressed to the right position, spring 15 is compressed again to trigger the tongue pressing action. This step-by-step logic of first fixing the internal parts and then locking the external structure ensures the assembly quality from the action sequence and reduces the problem of tongue pressing failure caused by roller 9 not being in place.

[0038] Finally, during the final stage of force application by cylinder 11, the cutter 14 at the front end of top plate 12 cooperates with the cutting seat 4 connected to the end of conveyor frame 3 to cut the finished retainer after the metal tongue 10 has been pressed. After all the secondary pressing, tongue pressing, and fixed-length cutting processes of the retainer are completed, cylinder 11 pulls top plate 12, transition plate 207, and bottom plate 1701 in reverse order to lift. At this time, the rack 1601 at the rear end of top plate 12 meshes with gear 1602 on one side of bracket 1604. Gear 1602 then rotates through one-way bearing 1603 to the conveyor wheel 1605 on the other side of bracket 1604. The one-way bearing 1603 allows gear 1602 to idle and cut the rotation of conveyor wheel 1605 during the downward stroke of cylinder 11. A transmission connection is established between gear 1602 and conveyor wheel 1605 during the lifting stroke. Then, through the snap-fit ​​engagement between the outer guide pin 1606 of conveyor wheel 1605 and the positioning hole 7 at the side end of the cage material belt 6, the intermittent conveying of the cage material belt 6 is achieved during the reset stroke of cylinder 11. The previously processed cage is pushed out of the end of conveyor frame 3 and automatically cut off in the next stroke. This application integrates three processes in the downward stroke of cylinder 11: secondary pressing, tongue pressing, and fixed-length cutting. During the lifting and reset stroke of cylinder 11, the gear 1602 with a one-way bearing 1603 is linked to drive conveyor wheel 1605 to achieve intermittent conveying of cage material belt 6. Multiple processes are coordinated through the same power source, and the assembly efficiency is effectively improved by optimizing the linkage between various structural components.
