Description

Technical Field

[0001] The utility model belongs to the field of mobile phone case production equipment, and specifically relates to a dispensing mechanism for installing buttons on a mobile phone case. Background Technique

[0002] Mobile phones are one of the essential items in people's lives and work. With the development of society, mobile phones have more and more functions. However, the only thing that remains unchanged is that the volume keys and power keys of mobile phones have not been cancelled. Therefore, corresponding positions for the volume keys and power keys will also be reserved on mobile phone cases. In terms of technology, if it is a metal or hard mobile phone case, the through-hole method is usually used for clearance, while for those made of silicone material, it is much simpler and basically all are integrally injection-molded;

[0003] However, not only are there new models of mobile phones, but mobile phone cases also have different requirements. The current proposed solution is to manufacture the mobile phone case and the buttons separately, and then use the dispensing method for connection. Since the buttons are very small and the glue is easy to stick, in the case of a large production volume, it is obviously impossible to meet the requirements by assembling them one by one manually. Therefore, our company has developed a dispensing and assembling production equipment for mobile phone buttons according to the processing requirements. Since the buttons are very small in volume, the dispensing step is particularly crucial. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dispensing mechanism for installing buttons on a mobile phone case to solve the problems raised in the above background technique.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figures 1-5 ;

[0025] The dispensing mechanism of the present invention can perform dispensing operations on buttons in all directions, providing guarantee for the subsequent fixation of the buttons to the mobile phone case. Specifically, it includes a multi-axis moving component 11 and a transverse moving component 21; the movable end of the multi-axis movement is equipped with a dispensing component 12; in this embodiment, the multi-axis moving component 11 can only have a lifting function. If a cleaning component 51 for cleaning the spray valve of the dispensing component 12 is further included, the multi-axis moving component 11 can have the function of moving in multiple directions. Preferably, since there will be a wire drawing phenomenon at the spray valve after the dispensing component 12 finishes dispensing, it is necessary to clean the spray valve. Therefore, after each dispensing is completed, the multi-axis moving component 11 drives the dispensing component 12 to move into the cleaning component. Specifically, the spray valve can be in contact with the non-woven fabric, and the residual glue at the spray valve is cleaned by driving the non-woven fabric to roll.

[0026] The movable end of the transverse movement component 21 is installed with a rotating component 22, and an adsorption head 23 for acquiring the key is installed on the rotating component 22. The transverse movement component 21 drives the rotating component 22 to move back and forth between the key feeding device and the dispensing position. First, the key is placed in the profiling groove 24, and then the adsorption head 23 generates suction to fix the key on the adsorption head 23. The dispensing position is a circle around the outer periphery of the key. Therefore, the depth of the profiling groove 24 should be less than the thickness of the key, so that the key protrudes from the profiling groove 24, and the back surface of the key is placed in the profiling groove 24. Then, the transverse movement device drives the rotating component 22 to move to the position corresponding to the dispensing component 12. Before dispensing, the rotating component 22 is located below the dispensing component 12, and at the same time, the side surface of the key faces the spray valve of the dispensing component 12. Then, the dispensing component 12 moves downward to make the spray valve close to the side surface of the key, and at the same time, the spray valve sprays glue. The rotating component 22 drives the key to rotate 180°, so that the side surface of the key can be completely coated with glue. It should be noted that if the key is circular, the rotating component 22 only needs to drive it to rotate. If the key is oval, while the rotating component 22 drives the key to rotate, the multi-axis movement component 11 also needs to cooperate to drive the dispensing component 12 to move slightly up and down. These actions can all be realized through programs.

[0027] After acquiring the key through the rotating component 22 of the present utility model, it drives the key to rotate 360°. During the rotation process, the dispensing operation is carried out synchronously, so that the outer periphery of the key can be coated with glue. Based on the above structure, automatic dispensing and precise dispensing operations can be realized, providing a basic guarantee for the fully automatic operation of the overall equipment.

[0028] It should be noted that since the key is relatively small and the dispensing position is even smaller, the end of the spray valve in the dispensing component 12 is also relatively small, so that the glue can be output in the form of an injection needle, and the glue output volume can be controlled more precisely. In addition, a visual detection component 13 is also provided on the multi-axis movement component 11 for positioning the position of the key.

[0029] This utility model relates to an embodiment of the rotating assembly 22. Specifically, there is a mounting bracket 221. A first rotating component 222 is mounted on the mounting bracket 221. A fixed seat 223 is mounted at the output end of the first rotating component 222. A second rotating component 224 is mounted on the fixed seat 223. The second rotating component 224 is arranged at a 90° angle with the first rotating component 222. Initially, after the key is loaded, it is in a flat state, while when the key is being dot - glued, it is in a side - placed state. It can be seen from this that before dot - gluing, the key needs to rotate 90° in the Z - axis direction, changing from a flat state to a side - placed state. Specifically, a combination of a gear and a rack can be used to achieve a 90° rotation. However, this structure requires a large amount of moving space, has many parts, and has a slow response. Therefore, in this embodiment, the first rotating component 222 is used, which can specifically be a rotating cylinder or a small servo motor. Since the second rotating component 224 needs to rotate as a whole, a motor is preferably used as the rotating power. In the initial state, the rotating component faces downward, so that the suction head 23 also faces downward to pick up the key. Then, the first rotating component 222 drives the second rotating component 224 to rotate 90° along the Z - axis, changing the key from a flat state to a lateral state, making the side of the key correspond to the spray valve of the dispensing assembly 12. Then, the second rotating component 224 drives the suction head 23 to rotate, making the key rotate 360°.

[0030] Further, an induction switch 225 is provided on the mounting bracket 221, and an induction piece 226 cooperating with the induction switch 225 is provided on the fixed seat 223. Through the mutual cooperation of the induction switch 225 and the induction piece 226, it is used to control the rotation angle of the rotating component, ensuring that after driving the second rotating component 224 to rotate 90°, it stops operating.

[0031] In this utility model, there are also a first key placement seat 31 and a second key placement seat 32 arranged at both ends of the cross - moving assembly 21. First, the key is placed on the first key placement seat 31 through a key loading device. The key in this embodiment is provided with a bar code for tracking the flow of the product. Therefore, a bar code scanner 33 is provided at the position corresponding to the first key placement seat 31. After the product is scanned and entered through the bar code scanner 33, the suction head 23 picks up the key on the first key placement seat 31. Finally, after the dispensing operation is completed, the key is placed on the second key placement seat 32.

[0032] In this embodiment, the first key placement seat 31 and the second key placement seat 32 have the same structure. The first key placement seat 31 includes a lifting assembly 331. A fixed frame 332 is mounted on the moving end of the lifting assembly 331. A floating platform 333 is mounted on the upper end surface of the fixed frame 332. A pneumatic claw 334 is mounted on the floating platform 333. An active block 335 is provided at the action end of the pneumatic claw 334. The two active blocks 335 form a groove 336 for fixing the key.

[0033] Since the rotating component 22 does not have a lifting function, after scanning the code, the button placement base one 31 rises, pushing the button upward into the profiling groove 24 of the suction head 23. Then, the suction head 23 adsorbs and fixes the button. Then, the air gripper 334 opens the groove 336 to release the fixation of the button. At this time, the button is fixed by the suction head 23. After that, the lifting component 331 drives all the components on the fixing frame 332 to move downward to make space. Then, the transverse movement component 21 drives the rotating component 22 to move towards the dispensing component 12. It should be noted that the suction head 23 first contacts the floating platform 333 to play a buffering role. In addition, the specific implementation of the button placement base two 32 can refer to the button placement base one 31.

[0034] In the embodiment of the present utility model, a multi-joint manipulator 41 is provided near the button placement base two 32. An installation base 42 is provided at the end of the multi-joint manipulator. A cylinder 43 is fixedly provided on the installation base 42, and a suction component 44 is provided at the moving end of the cylinder 43;

[0035] In this embodiment, the button after dispensing is placed on the button placement base two 32, then the button is obtained by the suction component 44. Finally, the button position is transferred by the multi-joint manipulator 41 and inserted into the jig to be assembled with the mobile phone case. The function of the cylinder 43 is to push the suction component 44 downward, that is, to press and fix the button and the mobile phone case. The assembly process will not be described in detail here;

[0036] In another embodiment, the functions of the rotating component 22 and the suction head 23 are only to transfer the button from the button placement base one 31 to the button placement base two 32, then the button is obtained by the multi-joint manipulator 41 and cooperate with the dispensing component 12 for dispensing operation, and finally the button after dispensing is assembled in the mobile phone.
