Description

Technical Field

[0001] This utility model relates to the field of shell polishing technology, and in particular to a device for polishing and trimming the edges and corners of a power bank shell. Background Technology

[0002] As a widely used portable electronic device, power banks typically have casings made of plastic or metal through processes such as injection molding and die casting. After molding, the edges of the casing, especially the parting surface, ejector pin holes, and splicing lines, inevitably have defects such as burrs, flash, and excess material. These sharp edges not only affect the product's appearance and grip comfort but also pose multiple hidden dangers: they may scratch the user's skin or clothing; during subsequent assembly, metal or plastic debris may enter the internal circuitry, causing short circuits and other quality problems; in addition, rough edges also reduce the overall quality and market competitiveness of the product.

[0003] Traditional shell edge grinding and trimming equipment mostly requires manual handling of the shell during grinding. By moving the edges of the shell next to the high-speed rotating sandpaper, the sandpaper can grind the edges of the shell smooth. This method is not only labor-intensive but also somewhat dangerous. Utility Model Content

[0004] In order to overcome the disadvantages of traditional handheld shell polishing methods, which are labor-intensive and pose safety risks, the purpose of this utility model is to provide a device for polishing and trimming the edges of a power bank shell.

[0005] Technical solution: A device for grinding and trimming the edges of a power bank casing, comprising a worktable, foot pads, a controller, a motor, a support block, a driven shaft, a belt assembly, rollers, and sandpaper. Two foot pads are symmetrically fixed to the bottom of the worktable. A controller is installed on the front side of the worktable. A motor is installed on the top of the worktable. A support block is fixed to the top of the worktable. A driven shaft is rotatably connected to the top of the support block, and the support block is located behind the motor. The output shaft of the motor is connected to the driven shaft located on the top of the support block via a belt assembly. Both the top of the driven shaft and the output shaft of the motor pass through the belt assembly and are fixedly connected to rollers. Sandpaper is fitted on the outside of each roller.

[0006] Furthermore, it is particularly preferred that the device also includes slide rails, cylinders, slide frames, and a second motor. Slide rails are symmetrically installed on the top of the worktable, with both slide rails located to the right of the first motor. A cylinder is also installed on the top of the worktable, with the cylinder located to the right of the two slide rails. A slide frame is slidably connected between the two slide rails. The cylinder extension rod is connected to the right side of the slide frame. The second motor is installed at the bottom inside the slide frame. The controller is electrically connected to the first motor, the cylinder, and the second motor.

[0007] In addition, it is particularly preferred that the device also includes a rotating block, a limiting frame, and a power supply housing. The rotating block is connected to the second output shaft of the motor, the limiting frame is fixed to the top of the rotating block, and the power supply housing is placed inside the limiting frame.

[0008] In addition, it is particularly preferable that the sandpaper is designed to be detachable.

[0009] In addition, it is particularly preferred that both the foot pads and the limiting frame are made of silicone rubber, which has a good vibration isolation effect.

[0010] In addition, it is particularly preferred that the rollers are all made of rust-proof and corrosion-resistant 304 stainless steel.

[0011] Furthermore, it is particularly preferable that the operator can change the limiting frame of the required shape according to the different shapes of the power bank housing.

[0012] In addition, it is particularly preferable that the operator can change to different types of sandpaper according to the grinding and trimming needs of the corners of the power bank casing.

[0013] Furthermore, it is particularly preferable that when vibrations are transmitted from the ground or from operating electrical components, they are blocked after being transmitted to the silicone rubber feet and limit frames.

[0014] In addition, it is particularly preferred that the operator can increase or decrease the thickness of the sandpaper fitted on the outside of the roller according to the grinding and trimming needs of the corners of the power bank housing.

[0015] The above-mentioned technical solutions of one or more of the mobile power bank housing edge grinding and trimming equipment provided in this utility model embodiment have at least one of the following technical effects: 1. This utility model realizes automatic feeding and grinding of the mobile power bank housing by means of a motor, driven shaft, belt assembly, roller and sandpaper, in conjunction with slide rail, cylinder and slide frame. This design effectively replaces the traditional operation method of hand-holding the housing close to the high-speed rotating sandpaper, so that the operator does not need to directly touch the grinding area, thereby significantly reducing the risk of work injury, and freeing the manual labor from heavy manual work, achieving the effect of ensuring operation safety and saving manpower.

[0016] 2. This utility model, through a slide rail, cylinder, slide frame, motor II, rotating block, and limiting frame, can accurately position and smoothly transport the power bank housing to the grinding station. Motor II drives the rotating block and limiting frame to slowly rotate the housing, so that each edge and corner of the housing can contact the high-speed rotating sandpaper in sequence and evenly. This process ensures the continuity and consistency of the grinding action, and achieves the effect of effectively removing burrs and improving the uniformity of trimming and the stability of product quality.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 4As shown, the assembly includes a worktable 1, foot pads 2, a controller 3, a motor 4, a support block 5, a driven shaft 61, a belt assembly 6, rollers 7, and sandpaper 8. Two foot pads 2 are symmetrically fixed to the bottom of the worktable 1. The controller 3 is mounted on the front of the worktable 1. The motor 4 is fixedly mounted on the top of the worktable 1. The support block 5 is fixedly connected to the top of the worktable 1, and the driven shaft 61 is rotatably connected to the top of the support block 5. The support block 5 is located behind the motor 4, and the output shaft of the motor 4 is positioned between the output shaft of the motor 4 and the driven shaft 61 located on the top of the support block 5. The driven shaft 61 and the output shaft of the motor 4 are connected by a belt assembly 6. Both the top of the driven shaft 61 and the output shaft of the motor 4 pass through the belt assembly 6 and are fixed with rollers 7. Sandpaper 8 is fitted on the outside of each roller 7. The sandpaper 8 is detachable. The rollers 7 are made of rust-proof and corrosion-resistant 304 stainless steel. The operator can change different types of sandpaper 8 according to the grinding and trimming needs of the corners of the power bank housing 15. When vibration is transmitted from the ground or the running electrical components, it will be blocked after being transmitted to the silicone rubber foot pads 2 and the limit frame 14.

[0035] like Figures 1-3 As shown, it also includes slide rails 9, cylinders 10, slide frames 11, and motor 12. Slide rails 9 are symmetrically fixedly installed on the top of the worktable 1, with both slide rails 9 located to the right of motor 4. Cylinders 10 are also fixedly installed on the top of the worktable 1, located to the right of the two slide rails 9. A slide frame 11 is slidably connected between the two slide rails 9. The telescopic rod of cylinder 10 is connected to the right side of slide frame 11. Motor 12 is fixedly installed at the bottom inside slide frame 11. Controller 3 is electrically connected to motor 4, cylinder 10, and motor 12. It also includes a rotary... The moving block 13, the limiting frame 14, and the mobile power supply housing 15 are connected to the output shaft of the motor 2 12. The rotating block 13 is fixed to the top of the rotating block 13. The mobile power supply housing 15 is placed inside the limiting frame 14. The foot pad 2 and the limiting frame 14 are both made of silicone rubber with good vibration isolation effect. The operator can change the limiting frame 14 to the required shape according to the different shapes of the mobile power supply housing 15. The operator can increase or decrease the thickness of the sandpaper 8 sleeved on the outside of the roller 7 according to the grinding and trimming needs of the corners of the mobile power supply housing 15.

[0036] When using this device to grind the edges and corners of the power bank housing 15, the power supply of the device must first be turned on and the device started through the controller 3. At this time, the operator can place the power bank housing 15 to be processed securely inside the limiting frame 14. The limiting frame 14 is specially designed to effectively limit the displacement of the housing during the processing and ensure its accurate position. After placement, the operator can conveniently load and unload the power bank housing 15 by holding the handle on the top of the power bank housing 15. It also provides convenience for possible manual fine-tuning. After the power bank housing 15 is fixed in place in the limiting frame 14, the operator can start the motor 4 through the controller 3. After the motor 4 starts, its output shaft begins to rotate and transmits power to the driven shaft 61 on the top of the support block 5 through the belt assembly 6. The stable operation of the belt assembly 6 causes the two rollers 7 connected symmetrically to it to rotate synchronously at high speed, thereby driving the sandpaper 8 sleeved on the outside of the rollers 7 to rotate at high speed.This sandpaper 8 grinding module constitutes the core grinding unit of the equipment, providing continuous and uniform grinding power for the corner treatment of the power supply housing 15. Simultaneously with the start of the core grinding unit, the operator needs to activate cylinder 10 and motor 12 via controller 3. After cylinder 10 is activated, its extension rod pushes the slide frame 11 to move smoothly to the left along the two slide rails 9. The slide rails 9 ensure the accuracy and stability of the slide frame 11's movement trajectory. Motor 12 is installed at the bottom inside the slide frame 11. The output shaft of motor 12 is connected to rotating block 13. The top is fixed with a limiting frame 14 that supports the power bank housing 15. Therefore, the movement of the sliding frame 11 accurately transports the power bank housing 15 to the sanding area of ​​the high-speed rotating sandpaper 8. After the power bank housing 15 is sent into the sanding area, the high-speed rotating sandpaper 8 begins to grind and trim its edges. To further ensure the uniformity and thoroughness of the sanding, especially when dealing with complex or irregular edges, motor 12 can be started. Motor 12 drives the rotating block 13 to rotate slowly, and the rotating block 13 drives the limiting frame 14 and the power bank housing on it. The body 15 rotates slowly, allowing each edge and corner of the housing to contact the sandpaper 8 sequentially and comprehensively, thus achieving automated grinding and trimming of the housing's edges and corners. After the grinding process is completed, the operator operates the cylinder 10 again via the controller 3, causing its telescopic rod to retract and move the slide frame 11 to the right along the slide rail 9, thereby smoothly removing the power bank housing 15 from the grinding station. Finally, the operator cuts off the power supply and uses the handle to remove the trimmed power bank housing 15 from the limit frame 14, thus completing the entire processing. In this process, when the sandpaper 8 needs to be replaced after a long period of use, the sandpaper 8 fitted on the outside of the roller 7 can be removed and a new sandpaper 8 can be fitted. This equipment consists of a main grinding system composed of motor 4, belt assembly 6, roller 7 and sandpaper 8, and a precision feeding and rotation system composed of slide rail 9, cylinder 10, slide frame 11, motor 12, rotating block 13 and limit frame 14. This achieves semi-automatic, high-efficiency, high-consistency and safe and reliable grinding and trimming of the corners of the power supply housing 15. At this time, the grinding and trimming of the corners of the power supply housing 15 is completed.
