[0002] With the development of science and technology, people can no longer live without mobile phones. In order to better protect and decorate mobile phones, a mobile phone case is usually put on the outside of the mobile phone. Nowadays, there are many forms of mobile phone cases, including one-piece injection molding and split types. Moreover, for special designs, the mobile phone case and buttons are made separately; for example, the current new iPhone 16 mobile phone, the volume button is convex outward, and the camera button is concave inward, but the buttons on the mobile phone case need to all protrude outward. The mobile phone case made by one-piece injection molding does not feel good at the position corresponding to the camera button, and it is difficult to trigger. Therefore, a split design is adopted. For this purpose, the company has designed a production equipment that combines a mobile phone case with a separate button, such as the public technical documents "CN118744075A, a mobile phone case with additional buttons assembly production line" and "CN118768159A, a mobile phone case button installation production line".

[0003] Since the buttons on the mobile phone case are relatively small, the assembly needs to be very precise. However, whether the buttons are stamped or injection molded, burrs or unevenness will occur on the edges of the buttons.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Please refer to Figure 1-7 ;

[0033] The device described in the present invention is intended to pre-process the manufactured keys so that they can be better assembled with the mobile phone case, and specifically includes a turntable device 1, a feeding device 2, a grinding device 3 and a cleaning device 4. A jig assembly 5 for placing keys is installed on the turntable device 1; the main processing position for the keys is at the edge, and the steps are divided into two steps: grinding and cleaning, wherein the grinding is to remove burrs on the periphery of the keys and to grind the periphery of the keys flat, and then the periphery of the keys is cleaned; it should also be noted that the feeding device 2 includes a storage assembly and a conveying assembly, and its function is to transfer the keys on the storage assembly to the jig through the conveying assembly. Preferably, the conveying assembly can include two steps of loading and taking out. After the key processing is completed, the keys on the jig assembly 5 are taken out by the conveying assembly and placed in a tray, and then the keys to be processed on the tray are placed in the jig. The method for obtaining the keys can be vacuum adsorption. For details, reference can be made to the relevant structure of the prior art, which will not be repeated here.

[0034] Furthermore, the button is in the shape of a strip, so it is necessary to rotate the button 360° during operation to grind and clean it, while the grinding device 3 and the cleaning device 4 are in two different positions, and the rotation of the jig requires the use of a rotating device 7. Generally, the rotating device 7 is a rotating cylinder 61 or a motor. If the rotating device 7 is installed on the turntable device 1, when the position needs to be switched, it will cause dragging of the air pipe or the wire, limiting the rotation angle, and making it impossible to achieve cyclic rotation; for this reason, the rotating device 7 and the turntable device 1 in this embodiment adopt a separate structure, and the rotating device 7 is fixed at a certain position. When the jig assembly 5 is rotated to a specified angle, the rotating device 7 is combined with the jig assembly 5.

[0035] During operation, the key to be processed is placed into the jig assembly 5 through the feeding device 2, and then the jig assembly 5 is driven by the turntable device 1 to reach the grinding device 3 first, and then the upper end surface of the key is pressed by the pressing device 6 to press the key onto the jig assembly 5 to prevent the key from being separated from the jig assembly 5 or being displaced during the grinding operation. At the same time, the rotating device 7 is combined with the jig assembly 5, and the periphery of the key is exposed. Then the grinding device 3 is pushed forward to make the silicone pad 31 contact the periphery of the key through the grinding belt. In this process, the grinding belt is in a rolling state to grind the periphery of the key, and the key is stationary during the grinding process.

[0036] It should be noted that the shape of the key can be understood as a rectangular parallelepiped, and the position at the side width is an arc shape. It is necessary to perform a 360° grinding operation on the periphery of the key. When it is necessary to switch positions, for example, from the long side to the short side, the rotating device 7 drives the jig assembly 5 to rotate, and the clamping device 6 follows the rotation to ensure that the relative position of the key and the jig assembly 5 does not change. At the same time, the grinding device 3 retreats to adapt to the position change after the key is rotated. In addition, due to the use of the silicone pad 31 using the soft deformation property, it can adapt well to the shape of the arc end of the key and wrap it to avoid missing any place; when switching from the short side to the long side again, the grinding device 3 is pushed forward again to close to the long side of the key. In this process, the small burrs at the edge position of the circumference direction of the key can be removed, and the edge position of the key can be polished flat;

[0037] After completing the polishing step, there will be some dust on the periphery of the key that needs to be cleaned, so the rotating device 7 at the corresponding polishing device 3 is separated from the jig assembly 5, and then the jig assembly 5 is driven to move to the cleaning device 4 through the turntable device 1, and then another rotating device 7 is combined with the jig assembly 5. The cleaning device 4 has the same action form as the polishing device 3, and can adjust its position according to the state of the key. The silicone pad 2 462 uses the soft deformation property to adapt well to the shape of the arc end of the key and wrap it to avoid missing any place. In addition, a cleaning belt is used. During the cleaning process, the cleaning belt is also in a rolling manner to wipe the key. In addition, the dust attached to the surface of the key can be removed by wet wiping.

[0038] The present invention can pre-process the keys through the cooperation between the polishing device 3 and the cleaning device 4, so that the keys can better meet the assembly standards. In addition, an independent rotating device 7 is designed. The rotating device 7 is combined with the jig assembly 5 only after the jig assembly 5 reaches the specified position, so it will not drag the wire, so that the turntable device 1 can achieve wireless circular rotation, and after the rotating device 7 is combined with the jig assembly 5, it can also fix the position, that is, there is no need to add other devices to achieve positioning, thereby simplifying the overall structure.

[0039] The present invention is directed to one of the embodiments of the fixture assembly 5, which specifically includes a fixed seat 51, which is rotatably connected to a transmission rod 52. Of course, bearings and other components can be arranged between the two to make the rotation smoother. One end of the transmission rod 52 extends downward from the fixed seat 51 and can correspond to the rotating device 7. The rotating device 7 has a lifting function. When connection is required, it rises and combines with the transmission rod 52 to achieve transmission and fixation. When separation is required, it descends and disengages from the end of the transmission rod 52 to achieve contact locking. The other end of the transmission rod 52 extends upward from the fixed seat 51 and is connected to a bearing seat 53. A flange 54 for bearing a key is provided on the surface of the bearing seat 53. The surface area of ​​the flange 54 is smaller than the bottom area of ​​the key. A movable plate 55 is sleeved on the outer periphery of the flange 54. A groove 56 adapted to the key is provided at the position of the movable plate 55 corresponding to the flange 54. A plurality of springs 57 are provided between the movable plate 55 and the bearing seat 53.

[0040] In this embodiment, the clamping device 6 has two devices corresponding to the grinding device 3 and the cleaning device 4 respectively, so there is no constraint when the key is loaded. In order to avoid the key from being offset, a groove corresponding to it must be set on the fixture assembly 5 to limit its position; under the action of a plurality of springs 57, the movable plate 55 lifts the groove 56 upward to protrude and form a placement position with the flange 54, and the position of the key is limited by the placement position; when the turntable device 1 reaches the position of the clamping device 6, the clamping device 6 applies pressure downward to the movable plate 55 and presses the key at the same time. At this time, the movable plate 55 moves downward, and the flange 54 and the key are exposed; because the surface area of ​​the flange 54 is smaller than the bottom area of ​​the key, the outer periphery of the key will extend the flange 54 laterally, and in addition, the part of the key pressed by the clamping device 6 does not completely cover the upper end surface of the key, and the upper surface of the key will also be exposed along the circumference direction. When grinding or cleaning, the exposed part of the key will be trapped in the grinding belt and the cleaning belt and wrapped, especially for the edge position of the cut hand, making it smooth;

[0041] In addition, when the grinding device 3 is switched to the cleaning device 4 , the clamping device 6 will be reset. During the rising process of the clamping device 6 , the movable plate 55 moves upward under the action of the spring 57 , and the key is defined again by the groove 56 .

[0042] Furthermore, the transmission rod 52 is of a special shape, for example, a prismatic column, so that power transmission can be achieved. Floating components 581 are installed on both sides of the fixed seat 51. The floating components 581 can be elastic telescopic components, and the extending floating protrusions 582 thereof abut against the outer side of the transmission rod 52. The two floating protrusions 582 are relatively arranged to form a clamping state for the transmission rod 52, thereby reducing vibration or eccentricity of the transmission rod 52 during rotation, and when the transmission shaft is disengaged from the rotating device 7, the current angle can be maintained, so that another rotating device 7 can be smoothly combined with it.

[0043] One embodiment of the clamping device 6 of the present invention specifically includes a cylinder 61, a mounting portion 62 is longitudinally provided at the output end of the cylinder 61, and a clamping portion 1 63 and a clamping portion 2 64 are respectively installed on the upper and lower parts of the mounting portion 62. In this embodiment, the clamping portion 1 63 is used to press the button, and the clamping portion 2 64 is used to apply pressure to the movable plate 55;

[0044] Furthermore, the clamping part 1 63 includes a fixed bracket 1 631, the lower end of which is rotatably connected to a pressure head 632, and the clamping part 2 64 includes a bracket 2 641 extending horizontally in a "C" shape, and a roller 642 is provided at the end of the bracket 2 641, and the roller 642 can contact the surface of the movable plate 55;

[0045] In this embodiment, the pressure head 632 has a height difference with the bracket, and the pressure head 632 corresponds to the middle empty space of the bracket. Under the action of the cylinder 61, the pressing part 1 63 and the pressing part move downward synchronously. First, the pressing part 2 64 will contact the movable plate 55 first, and as it continues to move downward, it will press the movable plate 55 downward to expose the key. After reaching a certain position, the pressing part 1 63 is close to the upper end surface of the key, and cooperates with the flange 54 to clamp and fix the key;

[0046] The rotating shaft of the rotating device 7 and the pressure head 632 are kept in a straight line. During the rotation process, the supporting seat 53 and the movable plate 55 rotate synchronously. The pressure head 632 keeps applying pressure to the key and rotates relative to the fixed bracket 1 631. Since the bracket 2 641 is provided with a roller 642, under the action of the roller 642, it can keep applying pressure to the movable plate 55, and at the same time, the movable plate 55 rotates smoothly.

[0047] There are two clamping devices 6, corresponding to the grinding device 3 and the cleaning device 4 respectively. Preferably, the two clamping devices 6 are fixed on a fixed plate, and a fixed column is provided at the bottom of the fixed plate and passes through the center of the turntable device 1 and can rotate relative to it.

[0048] One of the embodiments of the rotating device 7 of the present invention specifically includes a lifting component 71, and a driving motor 72 is installed at the output end of the lifting component 71. A connecting head 73 is provided at the output end of the driving motor 72. The connecting head 73 is provided with a socket 74 for the transmission rod 52 to enter. Preferably, the socket 74 is square, and the corresponding end of the transmission rod 52 is also square. A position sensor 75 is provided on the outer side of the connecting head 73. The setting of the position sensor 75 can ensure that the driving motor 72 drives the fixture component 5 to rotate 360° or rotate multiple times before resetting to the initial state and stopping.

[0049] In the embodiment of the present invention, a planar moving component 41 is provided at the bottom of the grinding device 3 and the cleaning device 4, and both have a lateral moving simulated wiping action during operation. The planar moving component 41 has an X-axis and a Y-axis moving direction. The Y-axis is used to control forward and backward movement, and the X-axis is used for lateral reciprocating motion to simulate the wiping action. For example, if there are hard burrs or dust adhering to the keys, they cannot be removed and cleaned only by rolling the grinding belt and the cleaning belt. Therefore, the simulated wiping method can increase the friction and better achieve the grinding and cleaning effects.

[0050] The polishing device 3 and the cleaning device 4 in the embodiment of the present invention have roughly the same structure and working principle, the difference is that the cleaning component uses a soaking method to wipe and clean, while the polishing device 3 does not need a soaking operation. The structure of the cleaning device 4 will be described below;

[0051] Specifically, it includes a bottom plate 42 installed on the plane moving component 41, on which a driving component 43, a material storage tray 44, a soaking component, a wiping part 461, a material receiving tray 47 and an adjusting rolling component 48 are installed, and a second silicone pad 462 is installed at the end of the wiping part 461, and limit posts 463 are provided on both sides of the second silicone pad 462 for winding a cleaning belt;

[0052] The cleaning tape is wound around all the above components, and the soaking assembly includes a liquid storage box 451, in which a sponge 452 is provided. The sponge 452 is provided with a crack 453 for the cleaning tape to pass through. When the cleaning tape passes through the sponge 452, the solution will adhere to it, and then it reaches the silicone pad 462 for cleaning operation.

[0053] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0054] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
