Description

Technical Field

[0001] This utility model relates to the field of notebook computer parts processing technology, specifically a grinding device for producing a coupling for a notebook computer screen hinge. Background Technology

[0002] Notebook accessory manufacturing refers to the process of transforming raw materials or semi-finished products into accessory products that meet design requirements through a series of processes such as machining, mold forming, surface treatment, assembly and testing, all centered around notebook computers and their peripheral devices. Its core objective is to meet the functional, structural reliability, aesthetic, and cost control requirements of notebook computers.

[0003] An existing patent (publication number: CN215470187U) discloses a grinding mechanism for couplings. The key technical points are: an operating table with a moving groove on one side and a rotating groove on the right side of the moving groove; a stepper motor fixedly fitted inside the rotating groove; a moving box movably engaged inside the moving groove; a steel wire wheel fixedly mounted on one end of the rotating shaft of a first drive motor; and a threaded hole on one side of the moving box, with two stabilizing holes on one side of the moving box. A load-bearing hole is also provided on one side of the operating table, with a bearing seat fixedly fitted inside the load-bearing hole. In use, the stepper motor is started to drive the lead screw to rotate. The lead screw is threaded into the threaded hole, and the moving column is movably engaged with the stabilizing hole, allowing the moving box to move. Then, the first drive motor is started to drive the steel wire wheel to rotate, achieving precise movement and fine grinding.

[0004] During use, the aforementioned device clamps the coupling using two clamping columns and grinds the coupling by the reciprocating linear movement of a wire wheel, achieving precise movement and meticulous grinding. However, during the grinding process, because the wire wheel and the coupling are in a horizontal position, it is difficult to grind the corners at both ends of the coupling, resulting in grinding blind spots at the corners. These insufficiently ground areas may retain burrs, thus affecting the subsequent use of the coupling. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding device for manufacturing couplings of laptop screen hinges, which has advantages such as improving the grinding quality of couplings and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for producing a coupling of a laptop screen hinge, comprising a processing base, an auxiliary component for assisting in grinding the coupling is provided in the central area of ​​the upper surface of the processing base, and a loading and unloading component is provided corresponding to the auxiliary component. Two rotating rods are provided above the auxiliary component, and two arc-shaped transmission wheels and a cylindrical transmission wheel are respectively fixedly connected to the circumferential surfaces of the two rotating rods. The circumferential surfaces of the two arc-shaped transmission wheels are both arc-shaped, and the arc-shaped transmission wheels and the cylindrical transmission wheels are connected through the grinding component.

[0007] A sliding frame is provided between the two rotating rods. A sliding rod is fixedly connected to the inner wall of the sliding frame. The diameter of the middle part of the sliding rod is larger than the diameter of both ends. Sliding cylinders are slidably sleeved at both ends of the sliding rod along its axis. Connecting plates are hinged to the circumferential surfaces of the two sliding cylinders. The two connecting plates are rotatably connected to the corresponding rotating rods. Springs are fixedly connected to one side of each of the two sliding cylinders. The two springs are fixedly connected to the sliding rods.

[0008] Furthermore, the grinding assembly includes a support frame fixedly installed on the upper surface of the processing base. A first electric push rod is fixedly installed on the inner top wall of the support frame. A shaped plate is fixedly connected to the output end of the first electric push rod. The two ends of the shaped plate are respectively rotatably connected to first transmission wheels via rotating shafts. A grinding belt is connected between the two first transmission wheels and the two arc-shaped transmission wheels and the cylindrical transmission wheel. The opposite ends of the two arc-shaped transmission wheels are in contact with the side of the grinding belt. Two guide rods are fixedly connected to the upper surface of the shaped plate and are slidably inserted into the inner top wall of the support frame.

[0009] With the above scheme, the first electric push rod can push the irregular plate close to the coupling, and then drive one of the first transmission wheels to rotate through an external motor, so that it can drive the grinding belt to move. When the grinding belt contacts the coupling, the grinding belt can fit the arc structure of the arc transmission wheel, so that the grinding belt fits the arc of the corner of the coupling and performs grinding work on the corner of the coupling.

[0010] Furthermore, the grinding assembly also includes a slide rail mounted on the side of the irregular plate, a sliding frame slidably connected along the slide rail, and a second electric push rod fixedly mounted on the side of the irregular plate, with the output end of the second electric push rod fixedly connected to the sliding frame.

[0011] With the above scheme, the second electric push rod can push the sliding frame to slide vertically along the slide rail, so that the sliding frame can rise and fall vertically in a stable manner.

[0012] Furthermore, the auxiliary component includes a groove opened on the upper surface of the processing base, a support frame slidably connected inside the groove, and multiple bearing rods distributed at equal intervals rotatably connected to the side of the support frame, with a rubber sleeve fixedly installed on the circumferential surface of each bearing rod.

[0013] With the above solution, the load-bearing rod and rubber sleeve can fix the coupling during installation by interlocking the coupling with the rubber sleeve, thus keeping the coupling stable during the grinding process.

[0014] Furthermore, the auxiliary component also includes a gear fixedly connected to the circumferential surface of each bearing rod, a toothed plate that meshes with each gear fixedly connected to the upper surface of the machining base, a lead screw rotatably connected to the inner wall of the machining base, and a threaded sleeve that is threadedly connected to the lead screw fixedly installed at the end of the support frame away from the bearing rod.

[0015] The above scheme, with its gear and toothed plate meshing, allows the support frame to reciprocate within the groove via the threaded sleeve during the rotation of the lead screw. This meshes the gear and toothed plate, thereby driving the bearing rod and the coupling on it to rotate, resulting in more uniform grinding of the coupling surface.

[0016] Furthermore, the loading and unloading assembly includes a slide plate that is slidably connected to the inner wall of the processing base. Multiple mounting cylinders that are evenly distributed are fixedly installed on one side of the slide plate. A U-shaped material picking component is also fixedly connected to the side of the slide plate. The side of the material picking component corresponding to the multiple mounting cylinders has a wave-like structure. Two cylinders are fixedly installed on the upper surface of the processing base. The output ends of the two cylinders are fixedly connected to the slide plate.

[0017] The above scheme, with its matching mounting cylinder and material handling component, allows the coupling to be inserted into the mounting cylinder during loading. The cylinder then pushes the coupling into the rubber sleeve, securing it in place. When the ground coupling is removed, the cylinder resets the sliding plate, allowing the wave-shaped material handling component to contact the coupling and push it out, achieving automatic material removal.

[0018] Furthermore, the loading and unloading assembly also includes a feeding groove on the upper surface of the processing base. The feeding groove has an L-shaped structure, and the bottom end of the L-shaped structure passes through the side of the processing base. A collection box is slidably inserted into the inside of the feeding groove.

[0019] With the above scheme, the feed chute and collection box are designed so that when the coupling is removed after grinding, the coupling separated from the rubber sleeve can pass through the feed chute and fall into the collection box inside the feed chute, which facilitates the unified processing of the coupling after grinding.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This grinding device for manufacturing laptop screen hinge couplings utilizes an arc-shaped drive wheel. During grinding, the grinding belt adheres to the arc-shaped surface of the drive wheel after contacting the coupling, allowing it to grind the corners of the coupling. A grinding assembly adjusts the tension of the grinding belt to ensure stable contact between the belt and the coupling surface. An auxiliary assembly, via a support frame, moves the coupling being ground and rotates it, improving the grinding effect. Finally, an automatic loading and unloading assembly enables automatic loading and unloading of the coupling. Attached Figure Description

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Please see Figures 1-5 This embodiment discloses a grinding device for manufacturing a laptop screen hinge coupling. It includes a processing base 1, an auxiliary component 2 for assisting in grinding the coupling is located in the central area of ​​the upper surface of the processing base 1, and a loading / unloading component 3 is correspondingly provided with the auxiliary component 2. Two rotating rods 4 are located above the auxiliary component 2. Two arc-shaped transmission wheels 5 and a cylindrical transmission wheel 6 are fixedly connected to the circumferential surfaces of the two rotating rods 4, respectively. The circumferential surfaces of the two arc-shaped transmission wheels 5 are both arc-shaped. The arc-shaped transmission wheels 5 and the cylindrical transmission wheels 6 are connected by a grinding component 7. When grinding the coupling, the arc-shaped transmission wheels 5 can engage with the corner of the coupling through the grinding component 7, thus achieving grinding of the corner of the coupling.

[0037] A sliding frame 8 is provided between the two rotating rods 4. A sliding rod 9 is fixedly connected to the inner wall of the sliding frame 8. The diameter of the middle part of the sliding rod 9 is larger than the diameter of both ends. Sliding cylinders 10 are slidably sleeved at both ends of the sliding rod 9 along its axis. Connecting plates 11 are hinged to the circumferential surfaces of the two sliding cylinders 10. The two connecting plates 11 are rotatably connected to the corresponding rotating rods 4. Springs 12 are fixedly connected to one side of the two sliding cylinders 10. The two springs 12 are fixedly connected to the sliding rods 9. The cooperation between the springs 12 and the connecting plates 11 can provide a buffering force when the arc-shaped transmission wheel 5 and the cylindrical transmission wheel 6 contact the coupling through the grinding assembly 7, preventing the arc-shaped transmission wheel 5 and the cylindrical transmission wheel 6 from making rigid contact with the coupling.

[0038] The grinding assembly 7 includes a support frame 701 fixedly mounted on the upper surface of the processing base 1. A first electric push rod 702 is fixedly mounted on the inner top wall of the support frame 701. A shaped plate 703 is fixedly connected to the output end of the first electric push rod 702. The two ends of the shaped plate 703 are respectively rotatably connected to first transmission wheels 704 via rotating shafts. One of the first transmission wheels 704 is fixedly connected to the output end of an external motor. A grinding belt 705 is connected between the two first transmission wheels 704, two arc-shaped transmission wheels 5, and a cylindrical transmission wheel 6. The opposite ends of the two arc-shaped transmission wheels 5 are in contact with the side of the grinding belt 705. Two guide rods 706 are fixedly connected to the upper surface of the shaped plate 703 and are slidably inserted into the inner top wall of the support frame 701. The first electric push rod 702 can push... The movable irregular plate 703 approaches the coupling, and then one of the first transmission wheels 704 is driven to rotate by an external motor, which drives the grinding belt 705 to move. When the grinding belt 705 contacts the coupling, the grinding belt 705 can fit the arc structure of the arc transmission wheel 5, so that the grinding belt 705 fits the arc of the corner of the coupling and performs grinding work on the corner of the coupling. The grinding assembly 7 also includes a slide rail installed on the side of the irregular plate 703. The sliding frame 8 is vertically slidably connected along the slide rail. A second electric push rod 707 is fixedly installed on the side of the irregular plate 703. The output end of the second electric push rod 707 is fixedly connected to the sliding frame 8. The second electric push rod 707 can push the sliding frame 8 to slide vertically along the slide rail, so that the sliding frame 8 can be stably raised and lowered vertically.

[0039] Auxiliary component 2 includes a groove on the upper surface of the machining base 1. A support frame 201 is slidably connected inside the groove. Multiple bearing rods 202 distributed at equal intervals are rotatably connected to the side of the support frame 201. A rubber sleeve 203 is fixedly installed on the circumferential surface of each bearing rod 202. The bearing rods 202 and the rubber sleeves 203 can fix the coupling during installation by interference fit between the coupling and the rubber sleeves 203, thus keeping the coupling stable during grinding. Auxiliary component 2 also includes a gear 204 fixedly connected to the circumferential surface of each bearing rod 202. The upper surface of the machining base 1 is fixedly connected to each gear 204. The gear plate 205 is meshed with a lead screw 206 rotatably connected to the inner wall of the machining base 1. One end of the lead screw 206 is fixedly connected to the output end of an external motor. The end of the support frame 201 facing away from the bearing rod 202 is fixedly installed with a threaded sleeve 207 threadedly connected to the lead screw 206. The gear 204 and the gear plate 205 are engaged so that the support frame 201 can reciprocate in the groove through the threaded sleeve 207 during the rotation of the lead screw 206, so that the gear 204 meshes with the gear plate 205, thereby driving the bearing rod 202 and the coupling on the bearing rod 202 to rotate, which can make the surface of the coupling more evenly polished.

[0040] The loading and unloading assembly 3 includes a slide plate 301 slidably connected to the inner wall of the processing base 1. Multiple mounting cylinders 302, evenly distributed, are fixedly installed on one side of the slide plate 301. A U-shaped material-taking component 303 is also fixedly connected to the side of the slide plate 301. The material-taking component 303 has a wavy structure on one side corresponding to the multiple mounting cylinders 302. Two cylinders 304 are fixedly installed on the upper surface of the processing base 1. The output ends of both cylinders 304 are fixedly connected to the slide plate 301. The cooperation between the mounting cylinders 302 and the material-taking component 303 allows the coupling to be inserted into the mounting cylinder 302 during loading. Through the pushing of the cylinders 304, the coupling inside the mounting cylinder 302 can be interference-fitted onto the rubber sleeve 203, thus achieving the loading of the coupling. The coupling is fixed in place, and when the polished coupling is removed, the cylinder 304 drives the slide plate 301 to reset, so that the wave-shaped material pick-up part 303 can contact the coupling, thereby pushing the coupling out and realizing automatic material unloading. The loading and unloading assembly 3 also includes a feeding groove 305 opened on the upper surface of the processing base 1. The feeding groove 305 has an L-shaped structure, and the bottom end of the L-shaped structure passes through the side of the processing base 1. A collection box 306 is slidably inserted inside the feeding groove 305. The feeding groove 305 and the collection box 306 are provided so that when the polished coupling is removed, the coupling separated from the rubber sleeve 203 can pass through the feeding groove 305 and fall into the collection box 306 inside the feeding groove 305, which is convenient for uniform processing of the polished coupling.

[0041] It should be noted that each mounting cylinder 302 is coaxially arranged with the adjacent bearing rod 202 to ensure the accuracy of the coupling installation. During the movement, there is a gap between the corrugated structure of the material take-up part 303 and the rubber sleeve 203 to prevent them from contacting each other and interfering with the movement.

[0042] The working principle of the above embodiment is as follows: When installing the coupling, the operator inserts the coupling into multiple mounting cylinders 302 in sequence. Then, the cylinder 304 pushes the slide plate 301 to slide, so that the coupling in the mounting cylinder 302 is interference-fitted onto the corresponding rubber sleeve 203. Then, the cylinder 304 drives the slide plate 301 to reset, so that the material taking part 303 and the mounting cylinder 302 are separated from the two ends of the coupling by a certain distance.

[0043] During the grinding process, an external motor drives one of the first transmission wheels 704 to rotate via a rotating shaft. Simultaneously, the rotation drives the grinding belt 705 to move via another first transmission wheel 704, a cylindrical transmission wheel 6, and two arc-shaped transmission wheels 5. Subsequently, the second electric push rod 707 pushes the sliding frame 8 to slide along the slide rail on the irregular plate 703. During this process, the two rotating rods 4 can push the slide cylinder 10 to slide on the slide rod 9 via the connecting plate 11, compressing the corresponding spring 12. This allows the force of the spring 12 to be transmitted to the grinding belt 705 via the arc-shaped transmission wheel 5 and the cylindrical transmission wheel 6, keeping the grinding belt taut. Finally, the first electric push rod 702 pushes the irregular plate 703 down, causing the grinding belt 705 to contact the coupling. The coupling is then ground by the operation of the grinding belt 705.

[0044] Subsequently, an external motor drives the lead screw 206 to rotate, causing the lead screw 206 to drive the support frame 201 to reciprocate linearly along the slide groove through the threaded sleeve 207. When the support frame 201 reciprocates linearly, the gear 204 drives the bearing rod 202 and the coupling on the bearing rod 202 to rotate through meshing with the toothed plate 205, so that the grinding belt 705 can grind the coupling more evenly. When the coupling moves to the arc-shaped transmission wheel 5, the corner of the coupling will contact the grinding belt 705 and make the grinding belt 705 contact the arc-shaped surface of the arc-shaped transmission wheel 5, so that the grinding belt 705 fits against the corner of the coupling, thereby grinding the corner.

[0045] After the coupling is polished, the two cylinders 304 drive the slide plate 301 to move closer to the feed chute 305, so that the wavy structure of the material taking part 303 pushes out the coupling on the rubber sleeve 203. The pushed-out coupling can enter the collection box 306 through the feed chute 305, making it easy for the staff to collect.
