Description

Technical Field

[0001] The present invention belongs to the technical field of processing equipment, and specifically relates to a deburring and cleaning device for mobile phone case buttons. Background Art

[0002] With the development of technology, people are inseparable from 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. Now, there are various forms of mobile phone cases, including one-piece injection-molded cases and split cases. Moreover, for special-designed mobile phone cases, the cases and buttons are made separately; for example, in the current new model of Iphone16 mobile phone, the volume button protrudes outwards, while the camera button is concave inwards. However, the buttons on the mobile phone case need to all protrude outwards. The feel at the position corresponding to the camera button of the mobile phone case made by the one-piece injection-molding method is not good, and it is difficult to trigger. Therefore, a split design is adopted. For this reason, the company has designed a production device for combining a mobile phone case and a separate button, such as the publicly disclosed technical documents "CN118744075A, a mobile phone case additional button 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 requires very high precision. However, whether the buttons are made by stamping or injection molding, burrs or unevenness will be generated at the edge positions. The size of the burrs cannot be controlled, and it will affect the assembly effect with the mobile phone case. Summary of the Invention

[0004] The purpose of the present invention is to provide a deburring and cleaning device for mobile phone case buttons to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A deburring and cleaning device for mobile phone case buttons includes a turntable device, a feeding device, a grinding device, and a cleaning device;

[0007] A jig assembly for placing buttons is installed on the turntable device. Above the jig assembly, a pressing device is provided to press the button on the jig, exposing the outside of the button. A rotating device is installed below the turntable device, and the rotating device can be combined with the jig assembly to drive it to rotate, and the pressing device rotates along with it;

[0008] The grinding device rolls and conveys a grinding belt. A silicone pad I is provided near the jig. The grinding belt passes outside the silicone pad I, and the grinding device dynamically adapts to the shape of the button;

[0009] The cleaning device rolls and conveys a cleaning belt, and a second silicone pad is provided at a position close to the jig. The cleaning belt passes outside the second silicone pad, and the cleaning device dynamically adapts to the shape of the button.

[0010] In a further technical solution, the jig assembly includes a fixed seat. A transmission rod is rotatably connected to the fixed seat. One end of the transmission rod extends downward out of the fixed seat and can correspond to the rotating device, and the other end extends upward out of the fixed seat and is connected to a bearing seat. A flange for bearing the button is provided on the surface of the bearing seat. The surface area of the flange is smaller than the bottom area of the button, so that the outer edge of the button protrudes laterally and can be inserted into the grinding belt and the cleaning belt.

[0011] An activity plate is sleeved outside the flange. A groove adapted to the button is provided at a position of the activity plate corresponding to the flange. A plurality of springs are provided between the activity plate and the bearing seat.

[0012] The pressing device presses the button onto the flange and presses down the activity plate to expose the button.

[0013] In a further technical solution, the transmission rod is of a special shape. Floating components are installed on both sides of the fixed seat. The floating components protrude floating bumps and are in contact with the outer side of the transmission rod.

[0014] In a further technical solution, the pressing device includes a cylinder. An installation part is longitudinally provided at the output end of the cylinder. A first pressing part and a second pressing part are respectively installed above and below the installation part.

[0015] The first pressing part includes a first fixed bracket. The lower end of the first fixed bracket is rotatably connected with a pressing head.

[0016] The second pressing part includes a second bracket extending horizontally in a "C" shape. A roller is provided at the end of the second bracket. The roller can be in contact with the surface of the activity plate.

[0017] In a further technical solution, the rotating device includes a lifting component. A driving motor is installed at the output end of the lifting component. A connecting head is provided at the output end of the driving motor. A jack for the transmission rod to enter is provided on the connecting head. A position sensor is provided outside the connecting head.

[0018] In a further technical solution, a planar movement component is provided at the bottom of both the grinding device and the cleaning device, and both have a lateral movement during operation to simulate a wiping action.

[0019] In a further technical solution, the cleaning device includes a bottom plate installed on the planar movement component. A driving component, a material storage tray, a wetting component, a wiping part, a material receiving tray and an adjusting rolling component are installed on the bottom plate and cooperate with each other. The second silicone pad is installed at the end of the wiping part, and limiting columns are provided on both sides of the second silicone pad for winding the cleaning belt.

[0020] Advantages of the present invention:

[0021] Through the mutual cooperation of the grinding device and the cleaning device, the present invention can pre-process the key, making the key more in line with the assembly standard. In addition, with the independent rotating device design, the rotating device only combines with the jig component after the jig component reaches the specified position, so it will not drag the wire, enabling the turntable device to achieve wireless circular rotation. Moreover, after the rotating device combines with the jig component, it can also play a role in fixing the position, that is, there is no need to additionally add other devices to achieve positioning, simplifying the overall structure.

[0022] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation part. Brief Description of the Drawings

Detailed implementation manners

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

[0032] Please refer to Figure 1-7 ;

[0033] The device of the present invention is designed to pre - process the produced keys so as to be better assembled with the mobile phone case. Specifically, it includes a turntable device 1, a feeding device 2, a grinding device 3 and a cleaning device 4. A fixture assembly 5 for placing keys is installed on the turntable device 1. The main processing positions of the keys are at the edges, and the steps are divided into two steps: grinding and cleaning. Among them, grinding is to remove the burrs on the outer periphery of the keys and grind the outer periphery of the keys flat, and then clean the outer periphery of the keys. It should also be noted that the feeding device 2 includes a storage component and a conveying component, and its function is to transfer the keys on the storage component to the fixture through the conveying component. Preferably, the conveying component can include two steps: loading and picking. After the key processing is completed, the key on the fixture assembly 5 is taken out through the conveying component and placed in a tray, and then the key to be processed on the tray is placed in the fixture. The method of obtaining the key can adopt vacuum adsorption, and the specific structure can refer to the relevant structure of the prior art, which will not be elaborated 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 the grinding step is completed, there will be some dust on the outer periphery of the button that needs to be cleaned. Therefore, the rotating device 7 at the grinding device 3 is disengaged from the fixture assembly 5, and then the turntable device 1 drives the fixture assembly 5 to move to the cleaning device 4. Then, another rotating device 7 is combined with the fixture assembly 5. The cleaning device 4 has the same action form as the grinding device 3 and can adjust its position according to the state of the button. By using the silicone pad 462, which can utilize the property of soft deformation, it can well adapt to the shape of the arc-shaped end of the button and wrap it to avoid any omission. In addition, a cleaning belt is used, and during the cleaning process, the cleaning belt also wipes the button in a rolling manner. Specifically, the way of wet wiping can be adopted to remove the dust adhering to the surface of the button.

[0038] Through the mutual cooperation of the grinding device 3 and the cleaning device 4, the present invention can realize the pre-processing of the button, making the button more in line with the assembly standard. In addition, with the design of the independent rotating device 7, the rotating device 7 only combines with the fixture assembly 5 after the fixture assembly 5 reaches the designated position. Therefore, it will not drag the wire, enabling the turntable device 1 to achieve wireless circular rotation. Moreover, after the rotating device 7 combines with the fixture assembly 5, it can also play a role in fixing the position, that is, there is no need to additionally add other devices to achieve positioning, simplifying the overall structure.

[0039] One embodiment of the present invention for the fixture assembly 5 specifically includes a fixed seat 51. The fixed seat 51 is rotatably connected with a transmission rod 52. Of course, components such as bearings 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 to combine with the transmission rod 52 to achieve transmission and fixation. When separation is required, it descends to disengage 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 with a bearing seat 53. The surface of the bearing seat 53 is provided with a flange 54 for bearing the button. The surface area of the flange 54 is smaller than the bottom area of the button. An activity plate 55 is sleeved on the outer periphery of the flange 54. The activity plate 55 is provided with a groove 56 adapted to the button at the position corresponding to the flange 54. A plurality of springs 57 are arranged between the activity plate 55 and the bearing seat 53.

[0040] In this embodiment, the pressing device 6 has two units respectively corresponding to the grinding device 3 and the cleaning device 4. Therefore, when the buttons are loaded, they are not restricted. To avoid the situation of button misalignment, a slot adapted to it must be provided on the fixture assembly 5 to limit its position; under the action of several springs 57, the movable plate 55 is lifted upward, and the groove 56 protrudes to form a placement position with the flange 54, and the position of the button is limited by using this placement position; when the turntable device 1 reaches the position of the pressing device 6, while applying downward pressure on the movable plate 55 through the pressing device 6, the button is pressed tightly. At this time, the movable plate 55 moves downward, and the flange 54 and the button are both exposed; since the surface area of the flange 54 is smaller than the bottom area of the button, the outer circumference of the button will extend laterally beyond the flange 54. In addition, the part of the pressing device 6 that presses the button does not completely cover the upper end surface of the button, and the upper surface of the button will also be exposed along the circumference. When grinding or cleaning, the exposed part of the button will be wrapped by the grinding belt and the cleaning belt. Especially for the sharp edge position, it will be made smooth;

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

[0042] Further, the transmission rod 52 is of a special shape, such as a rhombic prism, so as to realize power transmission. Elastic telescopic components 581 are installed on both sides of the fixed seat 51. The elastic telescopic components 581 can be elastic telescopic components. The floating protrusions 582 they extend out are in contact with the outer side of the transmission rod 52. The two floating protrusions 582 are arranged oppositely to form a clamping state for the transmission rod 52, reducing the vibration or eccentricity when the transmission rod 52 rotates. Moreover, when the transmission shaft is disengaged from the rotating device 7, it can maintain the current angle, enabling another rotating device 7 to be smoothly combined with it.

[0043] One embodiment of the present invention regarding the pressing device 6 specifically includes a cylinder 61. A mounting portion 62 is longitudinally provided at the output end of the cylinder 61. A first pressing portion 63 and a second pressing portion 64 are respectively installed above and below the mounting portion 62. In this embodiment, the first pressing portion 63 is used to press the button tightly, and the second pressing portion 64 is used to apply pressure to the movable plate 55;

[0044] Further, the first pressing portion 63 includes a fixed bracket one 631. A pressing head 632 is rotatably connected to the lower end of the fixed bracket one 631. The second pressing portion 64 includes a bracket two 641 that extends horizontally in a "C" shape. A roller 642 is provided at the end of the bracket two 641. The roller 642 can be in contact with the surface of the movable plate 55;

[0045] In this embodiment, there is a height difference between the indenter 632 and the bracket, and the indenter 632 corresponds to the middle vacancy of the bracket. Under the action of the air cylinder 61, the first pressing part 63 and the pressing part drive the pressing part to move downward synchronously. First, the second pressing part 64 will contact the movable plate 55 first. As it continues to move downward, the movable plate 55 will be pressed downward to expose the button. After reaching a certain position, the first pressing part 63 will be close to the upper end face of the button and cooperate with the flange 54 to clamp and fix the button.

[0046] The rotating shaft of the rotating device 7 is in a straight line with the indenter 632. During the rotation process, the carrier seat 53 and the movable plate 55 rotate synchronously. The indenter 632 rotates relative to the fixed bracket 631 while maintaining the pressure on the button. Since the second bracket 641 is provided with rollers 642, under the action of the rollers 642, it can maintain the pressure on the movable plate 55 and at the same time make the movable plate 55 rotate smoothly.

[0047] There are two pressing devices 6, corresponding to the grinding device 3 and the cleaning device 4 respectively. Preferably, both pressing devices 6 are fixedly arranged on the fixing plate. The bottom of the fixing plate is provided with fixing columns and penetrates through the center of the turntable device 1 and can rotate relative to it.

[0048] One embodiment of the rotating device 7 of the present invention specifically includes a lifting assembly 71. The output end of the lifting assembly 71 is installed with a driving motor 72. The output end of the driving motor 72 is provided with a connecting head 73. The connecting head 73 is provided with an insertion hole 74 for the transmission rod 52 to enter. Preferably, the insertion hole 74 is square, and the end of the corresponding transmission rod 52 is also square. A position sensor 75 is provided outside the connecting head 73. By setting the position sensor 75, it can be ensured that the driving motor 72 drives the jig assembly 5 to rotate 360° or rotate multiple circles and then reset to the initial position and stop.

[0049] In the embodiment of the present invention, both the grinding device 3 and the cleaning device 4 are provided with a planar movement assembly 41 at the bottom. During operation, both have a lateral movement to simulate the wiping action. The planar movement assembly 41 has the movement directions of the X-axis and the Y-axis. The Y-axis is used to control the forward and backward movement, and the X-axis is used for the lateral reciprocating movement to simulate the wiping action. For example, for harder burrs or dust adhering to the button, it is impossible to remove and clean them only by the rolling of the grinding belt and the cleaning belt. Therefore, adopting the simulation wiping method can increase the friction force and better achieve the grinding and cleaning effects.

[0050] In the embodiment of the present invention, the general structures and working principles of the grinding device 3 and the cleaning device 4 are the same. The difference is that the cleaning component uses a wetting method for wiping and cleaning, while the grinding device 3 does not require wetting operation. The structure of the cleaning device 4 will be described below.

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

[0052] The cleaning belt is wound around all the above components. The wetting component includes a liquid storage box 451. A sponge 452 is provided in the liquid storage box 451. A crack 453 for the cleaning belt to pass through is provided in the sponge 452. When the cleaning belt passes through the sponge 452, it will adhere to the solution and then reach the second silicone pad 462 for cleaning operations.

[0053] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

[0054] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
