Description

Technical Field

[0001] This utility model relates to the field of slide rail production equipment technology, specifically to an outer rail gripping and moving mechanism. Background Technology

[0002] Concealed drawer slides are widely used in furniture, cabinets, drawers, and other applications due to their advantages such as good concealment after installation, no extra space occupation, and clean appearance. Concealed drawer slides typically consist of outer rails, middle rails, and inner rails, and their production process requires precision machining and assembly of each rail. During the machining of the outer rails, machining equipment is needed to assemble them.

[0003] Currently, the outer rails of concealed slide rails are mostly processed manually, requiring manual placement and unloading. This necessitates placing the outer rails at the corresponding workstations on the processing equipment for assembly. After assembly, the assembled outer rails are unloaded and sent to the next processing step, increasing the labor intensity of workers and resulting in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to design an external rail gripping and moving mechanism that can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An outer rail gripping and moving mechanism includes a loading base and an intermittent conveying unit. The loading base has a material box and a loading platform on its top. The material box is located between the intermittent conveying unit and the loading platform. Several outer rails are stacked inside the material box. The loading platform has a first linear motor on its side near the material box. The mover of the first linear motor is fixedly connected to a base plate via a connecting rod. The bottom of the material box has a bottom hole, and the base plate is located below the bottom hole. The side of the material box has a side hole for the connecting rod to move upward. The top of the loading platform has a gripping unit for gripping and transferring the uppermost outer rail in the material box to the intermittent conveying unit. The intermittent conveying unit is used to intermittently convey the outer rails.

[0006] Furthermore, the gripping unit includes a horizontal cylinder, a lifting cylinder, and a clamping cylinder. The horizontal cylinder is fixed to the top of the loading platform, the lifting cylinder is fixed to the output end of the horizontal cylinder, and the clamping cylinder is fixed to the output end of the lifting cylinder.

[0007] Furthermore, the upper part of the material box has material holes on both opposite sides that cooperate with the clamping end of the clamping cylinder.

[0008] Furthermore, the intermittent conveying unit includes a second linear motor and two opposing support plates. The top of each support plate is provided with a plurality of limiting grooves evenly distributed along its length. The limiting grooves of the two support plates correspond one-to-one. The two ends of the outer rail are fitted onto the two corresponding limiting grooves. A hydraulic cylinder is fixedly connected to the mover of the second linear motor. The output end of the hydraulic cylinder is provided with two opposing top plates. The top of each top plate is provided with a plurality of limiting holes evenly distributed along its length. The limiting holes of the two top plates correspond one-to-one. Both top plates are located between the two support plates. The limiting holes and limiting grooves are correspondingly arranged.

[0009] Furthermore, the two support plates are fixedly connected by a connecting shaft, and the two top plates are fixedly connected by a connecting plate, with the bottom of the connecting plate fixed to the output end of the hydraulic cylinder.

[0010] Furthermore, the bottom of the material box is provided with two opposing support feet, and each of the opposite sides of the support feet is provided with a sliding groove. The top of the feeding base is provided with a slide rail that slides in cooperation with the sliding groove.

[0011] Furthermore, a limiting block is provided between the two slide rails corresponding to one of the support feet.

[0012] The beneficial effects of this utility model are as follows: The first linear motor drives the base plate to rise, which in turn pushes the stacked outer rails in the material box to rise, placing the top layer of outer rails in a position that the gripping unit can grasp. The gripping unit then grabs the top layer of outer rails in the material box and transfers it to the intermittent conveying unit. The intermittent conveying unit intermittently conveys the outer rails, causing them to pass intermittently through the processing area of ​​the processing equipment. After assembly, the outer rails continue to be sent to the next process for further processing. The entire process automates the loading of outer rails into the processing equipment for assembly, eliminating the need for manual unloading, greatly reducing the labor intensity of workers and improving production efficiency.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] like Figure 1-5 As shown, an outer rail gripping and moving mechanism includes a loading base 1 and an intermittent conveying unit. The top of the loading base 1 is provided with a material box 2 and a loading platform 3. The material box 2 is located between the intermittent conveying unit and the loading platform 3. Several outer rails 4 are stacked inside the material box 2. The loading platform 3 is provided with a first linear motor 5 on the side near the material box 2. The mover of the first linear motor 5 is fixedly connected to a base plate 7 through a connecting rod 6. The bottom of the material box 2 is provided with a bottom hole, and the base plate 7 is located below the bottom hole. The side of the material box 2 is provided with a side hole 8 for the connecting rod 6 to move upward. The first linear motor 5 drives the base plate 7 to rise, and the base plate 7 will push the stacked outer rails 4 in the material box 2 to rise, so that the outer rail 4 of the stacked outer rails 4 is in a gripping position. The top of the loading platform 3 is provided with a gripping unit that grips and transfers the outer rail 4 of the uppermost layer in the material box 2 to the intermittent conveying unit. The intermittent conveying unit is located next to the processing equipment and is used to intermittently convey the outer rails 4, so that the outer rails 4 intermittently pass through the processing area of ​​the processing equipment.

[0018] The gripping unit includes a horizontal cylinder 9, a lifting cylinder 10, and a clamping cylinder 11. The horizontal cylinder 9 is fixed to the top of the loading platform 3, the lifting cylinder 10 is fixed to the output end of the horizontal cylinder 9, and the clamping cylinder 11 is fixed to the output end of the lifting cylinder 10. Material holes 12 that mate with the clamping ends of the clamping cylinders 11 are provided on opposite sides of the upper part of the material box 2. Through the coordinated operation of the horizontal cylinder 9, the lifting cylinder 10, and the clamping cylinder 11, the material is loaded onto the outer rail 4. When the clamping cylinder 11 is directly above the material box 2, the lifting cylinder 10 drives the clamping cylinder... The cylinder 11 descends, positioning its gripping end at a position where it can grasp the outer rail 4. The gripping cylinder 11 then clamps the outer rail 4. Afterward, the lifting cylinder 10 raises the gripping cylinder 11 back to its initial height. Then, the horizontal cylinder 9 moves the lifting cylinder 10 horizontally, moving the gripping cylinder 11 above the intermittent conveying unit. Finally, the lifting cylinder 10 lowers the gripping cylinder 11, positioning its gripping end at a position where the outer rail 4 can be released. The gripping cylinder 11 then releases the outer rail 4, leaving it on the intermittent conveying unit.

[0019] The intermittent conveying unit includes a second linear motor 13 and two opposing support plates 14, which are fixedly connected by a connecting shaft 19. A plurality of limiting grooves 15 are evenly arranged along the length of the top of each support plate 14, with each groove corresponding to one of the two support plates 14. The two ends of the outer rail 4 are fitted onto the two corresponding limiting grooves 15. A hydraulic cylinder 16 is fixedly connected to the mover of the second linear motor 13. A connecting plate 20 is fixedly connected to the output end of the hydraulic cylinder 16. Two opposing top plates 17 are fixedly connected to the top of the connecting plate 20. A plurality of limiting holes 18 are evenly arranged along the length of the top of each top plate 17, with each hole corresponding to one of the two top plates 17. Both top plates 17 are located between the two support plates 14. The positioning holes 18 and the limiting grooves 15 are correspondingly set. The hydraulic cylinder 16 drives the two top plates 17 to rise through the connecting plate 20. The two corresponding limiting holes 18 can engage with the outer rail 4 placed between the two limiting grooves, allowing the outer rail 4 to rise with the top plate 17. After the outer rail 4 completely leaves the limiting groove 15, the mover of the second linear motor 13 will drive the hydraulic cylinder 16 to move a set distance in the conveying direction (this distance is the distance between two adjacent limiting grooves 15 on the same support plate 14). Then, the hydraulic cylinder 16 will drive the two top plates 17 to fall, allowing the outer rail 4 to be placed back on the corresponding limiting groove 15. This process moves the outer rail 4 in the conveying direction by the distance between two adjacent limiting grooves 15, achieving precise positioning and conveying of the outer rail 4 and improving processing quality.

[0020] The bottom of the material box 2 is provided with two opposing support feet 21. Each of the opposite sides of the support feet 21 is provided with a sliding groove 22. The top of the feeding base 1 is provided with a slide rail 23 that slides with the sliding groove 22. The material box 2 can be easily disassembled and replaced by sliding. A limiting block 24 is provided between the two slide rails 23 corresponding to one of the support feet 21. The limiting block 24 limits the material box 2 and positions it.

[0021] Among them, the first linear motor 5, the horizontal cylinder 9, the lifting cylinder 10, the clamping cylinder 11, the second linear motor 13, and the hydraulic cylinder 16 are all coordinated under the control of the controller. The horizontal cylinder 9, the lifting cylinder 10, and the clamping cylinder 11 are all powered by the air supply system, and the hydraulic cylinder 16 is powered by the oil supply system. All of these are existing technologies and will not be described in detail here.

[0022] Working principle: like Figure 1 , 2 As shown in Figure 5, when the outer rail gripping and moving mechanism is in use, the material box 2 with the stacked outer rails 4 is first installed on the loading base 1. At this time, the clamping cylinder 11 is located directly above the material box 2. Then, the controller is activated, and the lifting cylinder 10 will drive the clamping cylinder 11 to descend, so that the clamping end of the clamping cylinder 11 is in a position where it can grip the outer rail 4. Then, the clamping cylinder 11 will clamp the outer rail 4. After that, the lifting cylinder 10 will drive the clamping cylinder 11 to rise back to the initial height. (During this process, the first linear motor 5 drives the base plate 7 to rise, and the base plate 7 will push the stacked outer rails 4 in the material box 2 to rise a distance equal to the height of the outer rail 4.) Make the topmost outer rail 4 of the stacked outer rails 4 into a grippable position. Then, the horizontal cylinder 9 drives the lifting cylinder 10 to move horizontally, which in turn moves the clamping cylinder 11 to above the two support plates 14. Finally, the lifting cylinder 10 drives the clamping cylinder 11 to descend, so that the clamping end of the clamping cylinder 11 is in a position where the outer rail 4 can be released (at this time, the two ends of the outer rail 4 are placed on the two corresponding limit grooves 15). Then the clamping cylinder 11 will release the outer rail 4. Then the lifting cylinder 10 will drive the clamping cylinder 11 back to the initial height, and the horizontal cylinder 9 will drive the lifting cylinder 10 back to directly above the material box 2. During the time interval between the clamping cylinder 11 placing the outer rail 4 on the intermittent conveying unit, the hydraulic cylinder 16 drives the two top plates 17 to rise via the connecting plate 20. The two corresponding limiting holes 18 can engage with the outer rail 4 placed between the two limiting slots, allowing the outer rail 4 to rise with the top plate 17. After the outer rail 4 completely leaves the limiting slot 15, the mover of the second linear motor 13 will drive the hydraulic cylinder 16 to move a set distance in the conveying direction (this distance is the distance between two adjacent limiting slots 15 on the same support plate 14). Then, the hydraulic cylinder 16 will drive the two top plates 17 to fall, allowing the outer rail 4 to be repositioned in the corresponding limiting slot. On the slot 15, this process moves the outer rail 4 in the conveying direction by the distance between two adjacent limit slots 15. Then, the mover of the second linear motor 13 will drive the hydraulic cylinder 16 to return to its original position in the opposite direction of the conveying direction, in order to wait for the next conveying operation. During the time interval of the next conveying operation, the processing equipment next to the intermittent conveying unit will perform assembly operations on the outer rail 4 in the processing area. After the outer rail 4 is assembled, it will continue to be sent to the next process for processing. The whole process automates the loading of the outer rail to the processing equipment for assembly operations, and does not require manual unloading, which greatly reduces the labor intensity of workers and improves production efficiency.
