Description

Technical Field

[0001] The invention relates to the technical field of intelligent watch processing, and more specifically to a processing and cutting device for an intelligent watch shell. Background Art

[0002] A smart watch is an electronic device that integrates smart technology and traditional watch functions. It can not only display time, but also provide a variety of smart functions. The smart watch case is the external structure of the smart watch, which is responsible for protecting the internal electronic components and providing users with a wearable appearance. The shapes of smart watch cases vary, such as rectangle, circle, and oval, etc. During the production and processing process, the material must first be cut into the desired shape by cutting, and then the cut material must be processed into a dial of the desired shape by molding equipment.

[0003] In the prior art, the materials of watch casings are different, but the main method for cutting watch casings is laser cutting. The cutting drawings are designed through computer-aided design software, and various parameters of laser cutting are set according to the thickness of the material. Then the material to be cut is placed on the cutting platform, and at the same time, the material to be cut is ensured to be firmly fixed to prevent it from moving during the cutting process. After the cutting is completed, the area around the cut workpiece needs to be cleaned. Due to the special properties of some materials, such as aluminum alloy, brass, etc., the laser cutting effect is not ideal during the laser cutting process. Therefore, a water jet cutting device is used to cut the watch casing. The water jet cutting path is designed through computer-aided design software, and appropriate cutting parameters are selected. Then the material to be cut is fixed on the cutting platform to avoid position displacement during the water jet cutting process. However, in order to ensure that no excess material remains on the surface of the casing after water jet cutting, facing a thicker casing, the front and back sides are generally cut by exchanging cutting. However, manually turning over and then fixing the material to be cut can easily cause the material to be cut to be displaced. Since the water jet moving path is fixed, the water jet may miss or fail to cut the material to be cut, thereby affecting the processing accuracy of the smart watch casing.

[0004] In view of the above situation, the present invention designs a device for processing and cutting the housing of an intelligent watch to solve the above technical problems. Summary of the invention

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention provides a device for processing and cutting a smart watch shell. The device drives a rotating shaft to rotate by driving a motor. The rotating shaft rotates itself to make a fixed plate rotate forward and reverse, thereby realizing forward and reverse rotation of the fixed plate. The forward and reverse rotation of the fixed plate enables the material to be cut set in the fixed plate to be turned over, avoiding manual turning over so that the material to be cut deviates from the preset use path of the water jet, thereby ensuring that no excess material appears around the smart watch shell after water jet cutting, and further ensuring that the processing accuracy of the smart watch shell is not affected by human factors.

[0018] 2. The present invention provides a device for processing and cutting the shell of a smart watch. The device cooperates with a control component through the forward and reverse rotation of a fixed plate. The control component can block the loading hole opened on the fixed plate. When the fixed plate with the material to be cut is facing the water jet cutting device for cutting, the control component blocks the other side of the loading hole. When the material to be cut is cut, water can be prevented from splashing outside the cutting area, thereby reducing the generation of water mist and improving the safety of the operating environment. At the same time, when using abrasives, the control component can maintain the stability of the abrasive flow, ensuring that the abrasive is concentrated on the cutting position, thereby improving the cutting efficiency of the smart watch shell. At the same time, when the fixed plate is flipped, the control component completely seals the loading hole, thereby preventing the water jet cutting device from cutting other areas of the material to be cut, thereby avoiding additional material waste.

[0019] 3. The present invention provides a device for processing and cutting smart watch shells. The device uses a fixing component. Since the materials of the processed smart watch shells are different, the fixing component can fix the processed materials of various shapes. At the same time, when the excess material needs to be unloaded after the processing is completed, the fixing component can realize automatic unloading, thereby ensuring production efficiency and reducing labor costs.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] refer to Figure 1 , Figure 2 , Figure 3 A device for processing and cutting the shell of an intelligent watch, used for regular cutting of the metal shell of a watch, comprises a device body 1, a base 11 is arranged below the device body 1, and the base 11 is used to fix the device body 1 on a workbench, a loading bin 12 is installed above the base 11, a water jet cutting device 13 is arranged above the loading bin 12, and the water jet cutting device 13 can move on the plane above the device body 1; a control component 4 is arranged in the middle of the device body 1, a driving motor 2 is arranged on one side of the control component 4, and the driving motor The output end of the machine 2 is connected to a rotating shaft 3, and the rotating shaft 3 passes through the control component 4. The rotating shaft 3 is connected to a fixed plate 31 on the side away from the driving motor 2, and a loading hole 312 is opened on the fixed plate 31; the driving motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 rotates forward and reversely through its own rotation, so that the workpiece inside the loading hole 312 can be processed on both sides, and the rotation of the rotating shaft 3 drives the control component 4 to move, and the movement of the control component 4 blocks the loading hole 312 on the fixed plate 31 when the rotating shaft 3 rotates.

[0030] During the working process, the operator first determines the moving path of the water jet cutting device 13 through computer-aided design software according to the size of the watch case and the thickness of the material to be cut, and then places the material to be cut in the loading hole 312 on the fixed plate 31, and fixes the material to be cut in the loading hole 312 to avoid the material to be cut from deviating from the preset path during the water jet cutting process. After the material to be cut is fixed, the water jet cutting device 13 is started, and the water jet cutting device 13 will move along the preset moving path. At this time, the control component 4 will fit the bottom end of the fixed plate 31 to ensure that the water mist generated by the water jet cutting will not splash everywhere. At the same time, the control component 4 can guide the water flow of the water jet so that the water flow is concentrated in the cutting area, thereby improving the accuracy and consistency of the cutting. Due to the different thicknesses of the materials to be cut, when facing some thicker cutting materials, it is necessary to cut the front and back sides of the material to be cut. , thereby ensuring that the cut material has sufficient accuracy. Therefore, when the front processing of the material to be cut is completed, the drive motor 2 is started, and the drive motor 2 rotates to drive the rotating shaft 3 to rotate. Since the rotating shaft 3 is fixedly connected to a fixed plate 31 at one end away from the drive motor 2, when the drive motor 2 drives the rotating shaft 3 to rotate half a circle, the fixed plate 31 rotates half a circle synchronously. During the rotation of the fixed plate 31, the control component 4 will completely block the loading hole 312 on the fixed plate 31. At this time, there is no need to close the water jet cutting device 13, and the material to be cut will not be affected by the water jet cutting device 13. When the loading hole 312 on the other side of the fixed plate 31 faces the water jet, the control component 4 no longer blocks the loading hole 312. At this time, the water jet cutting device 13 can cut the material to be cut. This process is repeated until the required material is completely cut, thereby ensuring the accuracy of the water jet cutting of the material to be cut.

[0031] The control component 4 includes a fixed shell 41, a partition 42, a rotating plate 43, a control block 44, a control rod 45 and a baffle plate 46. The fixed shell 41 is arranged in the middle of the device body 1, and a driving motor 2 is arranged on one side of the fixed shell 41. The rotating shaft 3 connected to the output end of the driving motor 2 passes through the fixed shell 41. The interior of the fixed shell 41 is divided by the partition 42. A rotating plate 43 is arranged at the end of the fixed shell 41 away from the driving motor 2, and a control block 44 is connected to one side of the partition 42. Control rods 45 are symmetrically arranged on one side of the control block 44. The control rods 45 are connected to the baffle plate 46 at one end away from the control block 44, and the baffle plate 46 passes through the rotating plate 43.

[0032] During the working process, when it is necessary to block the loading hole 312 on the fixed plate 31, the driving motor 2 on one side of the fixed housing 41 is started, and the driving motor 2 drives the rotating shaft 3 to rotate. The rotating shaft 3 penetrates the partition 42 for installation, and the rotating shaft 3 is rotatably connected with the partition 42. The rotating shaft 3 is away from the fixed plate 31 connected to one side of the driving motor 2. The shielding plates 46 are symmetrically arranged on both sides of the fixed plate 31. The shielding plates 46 are connected to the control block 44 arranged on one side of the partition 42 through the control rod 45. Since the control block 44 is fixedly connected to the partition 42, when the rotating shaft 3 rotates the fixed plate 31, the shielding plates 46 are driven to move synchronously. The baffle plate 46 on one side of the fixed plate 31 facing the water jet cutting device 13 is controlled to cancel the blocking of the loading hole 312 through the control panel, and the baffle plate 46 on the other end of the loading hole 312 blocks the loading hole 312. At this time, the baffle plate 46 under the fixed plate 31 can guide the water flow of the water jet and gather the water flow in the cutting area, thereby improving the cutting accuracy. When the rotating shaft 3 is rotating, the baffle plates 46 on both sides of the fixed plate 31 complete the sealing of the loading hole 312, so that when the material to be cut is turned over, it can avoid being affected by the water jet, causing the material to be cut to deviate from the cutting area.

[0033] refer to Figure 4 , Figure 5 , Figure 6 The control block 44 is provided with a cylindrical groove 442, and the end surface of the control block 44 is provided with an annular limiting groove 441. One end of the control rod 45 is provided with a spherical protrusion 451, and the spherical protrusion moves in the limiting groove 441. Through such a setting, when the control rod 45 moves to the cylindrical groove 442, the control rod 45 drives the shielding plate 46 to move toward the direction of the driving motor 2. At this time, the shielding plate 46 no longer blocks the charging hole 312, so that the water jet cutting device 13 can cut the inside of the charging hole 312. When the material to be cut is cut, when the control rod 45 does not move in the cylindrical groove 442, the control rod 45 pushes the baffle plate 46 to block the loading hole 312. At this time, during the rotation of the rotating shaft 3, the material to be cut in the loading hole 312 will not be affected by the water jet cutting device 13. The spherical protrusion 451 set at one end of the control rod 45 moves in the annular groove set on the end face of the control block 44, thereby avoiding the control rod 45 from getting stuck during the movement, thereby improving the stability of the movement of the control rod 45.

[0034] A rectangular groove 431 is provided on the rotating plate 43, and a rectangular protrusion is provided at the connection between the rotating shaft 3 and the fixed plate 31. The rotating shaft 3 rotates to drive the rotating plate 43 to rotate synchronously through the fit of the rectangular protrusion and the rectangular groove 431. When the rotating shaft 3 rotates, the rotating shaft 3 can drive the rotating plate 43 to move synchronously through the fit of the rectangular protrusion and the rectangular groove 431. At this time, the fixed shell 41 can support the rotating plate 43, thereby improving the stability and smoothness of the overall device during the cutting process.

[0035] The baffle plate 46 is stepped, and the baffle plate 46 is arranged to penetrate the rotating plate 43, and one side of the baffle plate 46 is in contact with the surface of the fixed plate 31. A telescopic spring 461 is arranged in the middle of the baffle plate 46. When the stepped baffle plate 46 moves in contact with the surface of the loading hole 312, it can better seal the loading hole 312, and at the same time ensure that the water flow is evenly distributed in the cutting area, thereby avoiding a decrease in water jet cutting accuracy due to uneven water flow during the cutting process.

[0036] The fixing assembly 5 includes a fixing motor 51, a worm 52, a worm wheel 53, a clamping plate 54 and a fixing disk 55. A motion cavity 311 is opened inside the fixing plate 31. A fixing motor 51 is arranged at the bottom of the motion cavity 311. The output end of the fixing motor 51 is connected to the worm 52, and the center line of the worm 52 is perpendicular to the center line of the rotating shaft 3. A worm wheel 53 is arranged on one side of the worm 52, and the worm 52 and the worm wheel 53 are meshed with each other. A plurality of clamping plates 54 are arranged above the worm wheel 53, and a fixing disk 55 is arranged above the clamping plates 54. The rotation of the worm wheel 53 drives the clamping plates 54 to expand and contract on the fixing disk 55.

[0037] During the working process, in order to ensure that the material to be cut can be stably placed in the loading hole 312 during the cutting process, the worm 52 connected to one end of the fixed motor 51 rotates, and the rotation of the worm 52 drives the worm wheel 53 installed on one side to rotate, and the rotation of the worm wheel 53 causes the clamping plate 54 between the worm wheel 53 and the fixed disk 55 to shrink and expand. When the material to be cut is fixed, the worm 52 is driven to rotate by the fixed motor 51, and the worm 52 drives the worm wheel 53 to make multiple clamping plates 54 shrink toward the middle of the fixed disk 55, thereby clamping the material to be cut. When the water jet completes cutting the material to be cut, the worm 52 is turned over by the fixed motor 51, and the worm 52 drives the worm wheel 53 to rotate in the opposite direction, thereby causing the clamping plate 54 to expand to the outside of the fixed disk 55. At this time, the cut material falls into the loading bin 12.

[0038] The worm wheel 53 is provided with a plurality of mounting grooves 531 in an annular array, a limiting block 541 is provided on one side of the clamping plate 54 that is in contact with the worm wheel 53, and a fixing column 542 is provided on the other side of the clamping plate 54, and a plurality of moving grooves 551 are provided in an annular array on the fixing plate 55, the limiting block 541 moves in the mounting groove 531, and the fixing column 542 moves in the moving groove 551. Through such a configuration, when the worm wheel 53 rotates, the mounting groove 531 provided on the worm wheel 53 pushes the limiting block 541 provided on one side of the clamping plate 54 to move in the mounting groove 531, and at this time, the fixing column 542 provided on the other side of the clamping plate 54 moves in the moving groove 551, thereby realizing the contraction and expansion of the clamping plate 54. Due to the different sizes of the materials to be cut, the contraction and expansion of the clamping plate 54 can adapt to the materials to be cut of different sizes on the one hand, and on the other hand, can ensure the stability of the materials to be cut, and ensure that there is no problem of displacement of the materials to be cut during the cutting process.

[0039] The limit block 541 and the installation groove 531 are uniformly rectangular structures, the two ends of the movable groove 551 are semicircular, and the fixed column 542 is in contact with the movable groove 551. Through such an arrangement, when the limit block 541 on one side of the clamping plate 54 and the fixed column 542 on the other side of the clamping plate 54 are installed and the movable groove 551 can move, the clamping plate 54 can move steadily and smoothly, avoiding the clamping plate 54 from getting stuck during the movement, thereby improving the stability of the movement of the fixing component 5 and avoiding the problem that the clamping plate 54 cannot shrink and clamp the material to be cut.

[0040] The clamping plate 54 is arranged between the fixed disk 55 and the worm gear 53, and the front end of the clamping plate 54 is arranged to be a triangular structure, and multiple clamping plates 54 are contracted to form a polygon. Through such a setting, when the clamping plates 54 with a triangular structure are contracted and expanded, multiple clamping plates 54 can form a polygonal area. The polygonal area can adapt to the shapes of more materials to be cut, and at the same time, when fixing the material to be cut, it can provide sufficient clamping force for the material to be cut, thereby avoiding the phenomenon that the material to be cut is displaced during the cutting process and falls into the loading bin 12.

[0041] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
