Description

Technical Field

[0001] The present invention relates to the field of assembly equipment, and particularly to a volume switch cap assembly device. Background Art

[0002] The volume switch cap of a walkie-talkie is an important small component on the walkie-talkie, mainly used to adjust the volume of the walkie-talkie. Usually, operations such as rotation and pressing are used to control the increase and decrease of the volume. For example, clockwise rotation may increase the volume, and counterclockwise rotation decreases the volume. And some switch caps can also achieve specific functions such as muting when pressed, which is convenient for users to flexibly adjust the call volume according to the surrounding environment and actual needs. Therefore, when producing a walkie-talkie, it is necessary to assemble the volume switch cap on the walkie-talkie to better control the volume adjustment knob of the walkie-talkie.

[0003] When assembling the existing volume switch cap onto the walkie-talkie, manual operation is usually adopted, which not only increases the workload of labor, but also has a low degree of automation, resulting in a low work efficiency of assembly. Although there are also some volume switch cap assembly machines, it is difficult to accurately and effectively adjust the angles of the volume switch cap and the volume adjustment knob, which is likely to affect the accuracy of assembling the volume switch cap onto the walkie-talkie, and thus is likely to affect the quality of the walkie-talkie. And in order to improve the stability during the assembly process of the walkie-talkie, a positioning frame is usually set on the assembly machine. However, some of the existing positioning frames have a too simple structure and are only easy to place the walkie-talkie. Especially for some walkie-talkies with an arc-shaped outer surface, it is difficult for the positioning frame to stably clamp the walkie-talkie. Some have a too complex structure, and it is rather troublesome for the positioning frame to open and close, which is likely to affect the assembly efficiency of the volume switch cap.

Detailed implementation mode

[0036] In order to further explain the technical solution of the present invention, the following is elaborated in detail through specific embodiments.

[0037] As Figure 1 shown, the present invention provides a volume switch cap assembly device, including a workbench 1, and an electric turntable 2 for conveying walkie - talkies is arranged on the workbench 1;

[0038] As Figures 1 to 4 shown, in this embodiment, the top surface of the workbench 1 is provided with a material - taking manipulator 4 for clamping walkie - talkies, a rotating assembly 10 for adjusting the volume knob, a conveying adjustment assembly 11 for conveying and adjusting the volume switch cap, and a pressing assembly 12 for pressing the volume switch cap, which are distributed in a clockwise annular manner outside the electric turntable 2 in sequence;

[0039] It further includes a plurality of positioning frames 6 for positioning walkie - talkies, which are distributed at equal intervals in a ring on the electric turntable 2. The positioning frame 6 includes a fixed clamping frame 61 fixedly installed at the edge of the top surface of the electric turntable 2, a movable clamping frame 62 arranged outside the fixed clamping frame 61, two transmission rods 63 respectively installed at both ends of the movable clamping frame 62 and movably penetrating the front and rear end faces of the fixed clamping frame 61, and a fixed ring 64 fixedly sleeved on the transmission rod 63;

[0040] A plurality of positioning threaded holes 67 are formed in the movable clamping bracket 62. The positioning threaded holes 67 penetrate through the front and rear end faces of the movable clamping bracket 62. A hollow threaded cylinder 68 is installed with internal threads in the positioning threaded holes 67. A sliding rod 69 is slidably installed in the hollow threaded cylinder 68. A rubber block 610 is installed at one end of the sliding rod 69 facing the fixed clamping bracket 61. A pressure sensor 611 in close contact with the rubber block 610 is installed on the sliding rod 69 to detect the pressure exerted on the walkie-talkie by the rubber block 610 through the pressure sensor 611;

[0041] An installation groove 615 is formed at the front end inside the hollow threaded cylinder 68, and a micro motor 612 is fixedly installed in the hollow threaded cylinder 68. The output end of the micro motor 612 is installed with a threaded column 613 through a coupling. The threaded column 613 is in threaded connection with the inner side of a transmission threaded hole 614 formed on the sliding rod 69. The threaded column 613 is rotatably connected to the inner side of the hollow threaded cylinder 68 to drive the sliding rod 69 to move along the hollow threaded cylinder 68 by the rotation of the threaded column 613 in cooperation with the transmission threaded hole 614;

[0042] The fixed ring 64 is slidably connected to the inner side of a groove 65 formed on the fixed clamping bracket 61, and the fixed ring 64 is connected to the inner end face of the groove 65 through a first spring 66. The first spring 66 is sleeved on the transmission rod 63 movably;

[0043] A control board 616 is installed in the installation groove 615. Both the pressure sensor 611 and the micro motor 612 are electrically connected to the control board 616;

[0044] A fixed bracket 7 is installed on the workbench 1 between the material taking manipulator 4 and the rotating assembly 10. Three opening cylinders 8 are installed on the fixed bracket 7. The rightmost opening cylinder 8 corresponds to the positioning bracket 6 below the material taking manipulator 4. A push plate 9 facing the transmission rod 63 is installed on the piston rod of the opening cylinder 8;

[0045] Among them, two groups of rotating assemblies 10 and two groups of conveying and adjusting assemblies 11 are arranged on the workbench 1. The two groups of rotating assemblies 10 and the two groups of conveying and adjusting assemblies 11 are distributed in a staggered manner. The two groups of rotating assemblies 10 and the two groups of conveying and adjusting assemblies 11 are both located in the interval formed by the material taking manipulator 4 and the pressing assembly 12 at intervals in the clockwise circumferential direction, which is convenient for assembling two volume switch caps on the walkie-talkie simultaneously;

[0046] In this embodiment, a power supply 618 is also installed in the installation groove 615. The power supply 618 is electrically connected to the control board 616. Both the pressure sensor 611 and the micro motor 612 are electrically connected to the power supply 618, which is convenient for providing power for the pressure sensor 611 and the micro motor 612;

[0047] In this embodiment, a wireless module 617 is installed on the control board 616, and the wireless module 617 is a Bluetooth module, which is convenient for wirelessly transmitting the detected pressure on the walkie-talkie to the controller in the background, facilitating the timely monitoring of the clamping force on each part of the walkie-talkie;

[0048] In this embodiment, a belt conveyor 3 for conveying the assembled walkie-talkie is arranged outside the workbench 1, and an inclined U-shaped discharge frame 5 located between the belt conveyor 3 and the material taking manipulator 4 is installed at the top edge of the workbench 1, facilitating the walkie-talkie clamped by the material taking manipulator 4 to be introduced onto the belt conveyor 3 through the discharge frame 5;

[0049] Specifically, the push plate 9 is driven to move forward by the opening cylinder 8 at the front end, the push plate 9 drives the transmission rod 63 at the front end to move forward, the transmission rod 63 drives the fixed ring 64 and the movable clamping frame 62 to move forward. At this time, the distance between the movable clamping frame 62 and the fixed clamping frame 61 becomes larger, and the first spring 66 is elastically compressed under the pressure of the fixed ring 64. At this time, the walkie-talkie can be placed between the fixed clamping frame 61 and the movable clamping frame 62. When the electric turntable 2 drives the positioning frame 6 to rotate, the push plate 9 is separated from the transmission rod 63. At this time, the movable clamping frame 62 drives the rubber block 610 to reset under the elastic force of the first spring 66 to clamp and fix the walkie-talkie;

[0050] The pressure applied by the rubber block 610 is detected by the pressure sensor 611, and the data information is transmitted to the control board 616. The control board 616 processes the data information. When it is detected that the pressure of the rubber block 610 on the walkie-talkie is too large, the control board 616 controls the start of the micro motor 612. The micro motor 612 drives the threaded column 613 to rotate, and the threaded column 613 cooperates with the transmission threaded hole 614 to drive the sliding rod 69 to move inwards. The sliding rod 69 drives the rubber block 610 to move inwards. At this time, the pressure of the rubber block 610 on the walkie-talkie is reduced to prevent the outer surface of the walkie-talkie from being damaged due to excessive pressure of the rubber block 610. On the contrary, when it is detected that the pressure of the rubber block 610 on the walkie-talkie is small, the micro motor 612 rotates in the reverse direction, so that the sliding rod 69 drives the rubber block 610 to move outwards. At this time, the pressure of the rubber block 610 on the walkie-talkie increases until the pressure of the rubber block 610 on the walkie-talkie reaches the preset value, thereby realizing the stable clamping and fixing of the walkie-talkie by the fixed clamping frame 61, the movable clamping frame 62 and the rubber block 610;

[0051] Such as Figure 5As shown in the figure, in this embodiment, the rotating assembly 10 includes a support frame 101 fixedly installed on the top surface of the workbench 1, a lifting cylinder 102 installed on the top of the support frame 101, and a lifting frame 103 slidably installed on the support frame 101 and connected to the bottom piston rod of the lifting cylinder 102. A first motor 104 is locked and fixed on the lifting frame 103. A first jaw cylinder 105 is installed on the bottom output shaft of the first motor 104. A first detection module 106 is installed on the side surface of the first jaw cylinder 105;

[0052] The first detection module 106 uses a laser profile sensor to obtain the three-dimensional coordinate information of the profile of the walkie-talkie volume adjustment knob by emitting a laser beam to scan the surface of the walkie-talkie volume adjustment knob, and then judges the deflection angle of the walkie-talkie volume adjustment knob;

[0053] Specifically, when the electric turntable 2 drives the positioning frame 6 and the walkie-talkie to rotate and convey to the bottom of the rotating assembly 10, the first detection module 106 is used to detect the deflection angle of the walkie-talkie volume adjustment knob. When it is detected that the walkie-talkie volume adjustment knob is deflected, the lifting cylinder 102 drives the lifting frame 103 and the first jaw cylinder 105 to move downward. The first jaw cylinder 105 moves downward to clamp the volume adjustment knob of the walkie-talkie, and the first motor 104 drives the first jaw cylinder 105 to rotate. The first jaw cylinder 105 drives the volume adjustment knob to rotate until the volume adjustment knob rotates to the position.

[0054] As Figures 6 to 8 shown in the figure, in this embodiment, the conveying and adjusting assembly 11 includes a transfer frame 111 fixedly installed on the top surface of the workbench 1. A feeding track 112, a second motor 113 and a feeding manipulator 116 for conveying the volume switch cap are arranged on the transfer frame 111. A conveying plate 118 is slidably installed in the transfer frame 111. The output shaft of the second motor 113 is connected with a positioning rod 114 through a coupling. The positioning rod 114 movably penetrates the top surface of the transfer frame 111, and the positioning rod 114 is used to provide positioning for the volume switch cap;

[0055] A second detection module 115 is provided outside the positioning rod 114 and is installed on the top surface of the transfer frame 111. The second detection module 115 is a laser profile sensor for detecting the deflection angle of the volume switch cap. Two second gripper cylinders 117 are installed at the output end of the feeding robot 116. The distance between the two second gripper cylinders 117 corresponds to the distance from the positioning rod 114 to the volume adjustment knob of the intercom at the bottom of the feeding robot 116. The second gripper cylinder 117 is located above the positioning rod 114. A positioning groove 119 corresponding to the feeding track 112 is provided on the conveying plate 118 to receive the volume switch cap conveyed from the feeding track 112 through the positioning groove 119, and the side surface of the conveying plate 118 is connected to the piston rod of the conveying cylinder 1110 installed on the transfer frame 111. A limit assembly for providing positioning for the switch cap is provided in the positioning groove 119.

[0056] In this embodiment, the limit assembly includes a position sensor 11a that is locked and fixed in the transfer frame 111 and located above the positioning groove 119. The position sensor 11a is a reflective photoelectric sensor for detecting whether there is a volume switch cap in the positioning groove 119, a guide groove 11b provided on the inner bottom end surface of the positioning groove 119, and an electromagnet 11f installed in the guide groove 11b. The inner diameter of the guide groove 11b is smaller than the inner width of the groove 119. A limit block 11c for providing positioning for the switch cap is slidably installed in the guide groove 11b. The bottom end surface of the limit block 11c is installed with an iron piece 11d facing the electromagnet 11f. The iron piece 11d is connected to the inner side of the guide groove 11b via a second spring 11e.

[0057] The top of the limit block 11c is in the shape of a frustum that tapers from bottom to top, so that the upper end of the limit block 11c can accurately enter the inner side of the volume switch cap.

[0058] Specifically, the end of the feeding track 112 is connected to the output end of the external volume switch cap vibration disk, and the volume switch cap is fed into the feeding track 112 through the vibration disk. The volume switch cap slides along the feeding track 112 into the positioning groove 119. The position sensor 11a detects the volume switch cap, and then the electromagnet 11f is de-energized. The limit block 11c moves upward under the elastic force of the second spring 11e and enters the inner side of the volume switch cap. The conveying cylinder 1110 drives the conveying plate 118 to move, and the conveying plate 118 drives the positioning groove 119 and the volume switch cap to move out of the transfer rack 111.

[0059] Then, the two second jaw cylinders 117 are controlled to move by the feeding manipulator 116. The second jaw cylinder 117 at the front end clamps the volume switch cap, and as the feeding manipulator 116 moves, the volume switch cap is placed on the positioning rod 114. The second detection module 115 detects whether the angle of the volume switch cap is correct, and the second motor 113 drives the positioning rod 114 and the volume switch cap to rotate until the volume switch cap rotates to a preset angle. At this time, the angle of the volume switch cap is the same as that of the volume adjustment knob on the intercom. When the conveying cylinder 1110 drives the conveying plate 118 to move back to its original position, the electromagnet 11f is energized, and the iron sheet 11d moves downward under the suction of the electromagnet 11f and enters the guiding groove 11b. When the conveying plate 118 conveys the second volume switch cap, the second jaw cylinder 117 at the front end clamps the volume switch cap at this time, and the second jaw cylinder 117 at the rear end clamps the volume switch cap on the positioning rod 114. And as the feeding manipulator 116 works, it cooperates with the second jaw cylinder 117 at the front end to place the second volume switch cap on the positioning rod 114, and at the same time cooperates with the second jaw cylinder 117 at the rear end to place the first volume switch cap on the volume adjustment knob of the intercom. In this way, more volume switch caps are placed on the volume adjustment knob in a cycle.

[0060] As Figure 9 shown, in this embodiment, the pressing assembly 12 includes a column 121 locked and fixed on the top surface of the workbench 1, a pressing cylinder 122 fixedly installed on the top surface of the column 121, and a pressing block 123 slidably installed on the column 121 and connected to the piston rod of the pressing cylinder 122;

[0061] Specifically, as the electric turntable 2 continuously rotates, the positioning frame 6 drives the intercom with the volume switch cap to rotate to the position of the pressing assembly 12. At this time, the pressing cylinder 122 drives the pressing block 123 to move downward to apply pressure to the volume switch cap, so that the volume switch cap is pressed and fixed on the volume adjustment knob of the intercom. As the electric turntable 2 rotates continuously, the positioning frame 6 drives the assembled intercom to rotate to the right end of the workbench 1. The opening cylinder 8 at the right end drives the push plate 9 to move, and the push plate 9 pushes the transmission rod 63 to move outward again. The transmission rod 63 drives the movable clamping frame 62 and the rubber block 610 to move outward to separate from the intercom. The assembled intercom is clamped and discharged by the picking manipulator, and the assembled intercom is introduced into the belt conveyor 3 through the discharging frame 5. The assembled intercom is conveyed outward through the belt conveyor 3.

[0062] The present invention provides a volume switch cap assembly device. By rotating the rotating component 10, the volume adjustment knob on the rotating walkie-talkie is adjusted. The conveying and adjusting component 11 can convey and adjust the volume switch cap, so that the angle of the volume switch cap is consistent with the angle of the volume adjustment knob of the walkie-talkie, facilitating the accurate assembly of the volume switch cap onto the volume adjustment knob of the walkie-talkie. And through the pressing component 12, the volume switch cap is pressed and fixed on the volume adjustment knob, realizing the assembly of the volume switch cap of the walkie-talkie. The automation degree of its assembly process is high, reducing the manual workload and being beneficial to improving the assembly work efficiency of the volume switch cap of the walkie-talkie.

[0063] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
