[0032] The specific structure of the key automatic plug 1 mechanism will be mainly described below.

[0033] As Figures 1-3 and Figure 5 shown, a key automatic plug 1 mechanism includes a frame 100, a vibrating bowl 200, a moving module 300, a pressing fixture 400, and a robot 500. The vibrating bowl 200 is installed on the frame 100. The vibrating bowl 200 has a discharge port 210. The vibrating bowl 200 is used to vibrate the plug 1 in a preset direction and convey it to the discharge port 210. The moving module 300 is installed on the frame 100. The pressing fixture 400 is installed on the moving module 300. The pressing fixture 400 is used to fix the product and press the key of the product. The moving module 300 is used to drive the pressing fixture 400 to move to convey the product to the plug installation position. The robot 500 is installed on the frame 100. The robot 500 is used to clamp the plug 1 at the discharge port 210 and insert the plug 1 into the product located at the plug installation position, thereby locking the key of the product. In this embodiment, the product refers to a mobile phone that has assembled the key but has not assembled the plug 1.

[0034] After the buttons of products such as mobile phones are installed, place the product on the pressing fixture 400, and then the pressing fixture 400 fixes the product and presses the buttons of the product to prevent the buttons from falling off. The moving module 300 drives the pressing fixture 400 to move to convey the product to the pin installation position. At the same time, the vibrating disk 200 vibrates the pins 1 in a preset direction and conveys them to the discharge port 210. Then, the robot 500 clamps the pins 1 at the discharge port 210 and inserts the pins 1 into the product located at the pin installation position, thereby locking the buttons of the product and completing the assembly of the pins 1. This application does not require manual assembly of the pins 1. The robot 500 can ensure the precise assembly of the pins 1, will not scratch the product, and can be assembled successfully at one time. The assembly is fast and reliable.

[0035] In addition, in the prior art, manual assembly requires the cooperation of multiple people. This application can achieve the assembly of the pins 1 through the automatic button pin insertion mechanism, saving manpower.

[0036] In this embodiment, the pin installation position is a position (coordinate) set by the moving module 300, and the pin installation position is a position that the robot 500 can easily reach. The robot 500 can be a 4-axis robot or other multi-axis robots such as 6-axis robots. This application takes the 4-axis robot as the preferred embodiment.

[0037] Specifically, the pressing fixture 400 has a vacuum suction nozzle, and the pressing fixture 400 adsorbs and fixes the product through the vacuum suction nozzle. The pressing fixture 400 also has a pressing structure and a cylinder, and the cylinder can drive the pressing structure to press the buttons of the product.

[0038] In this embodiment, the moving module 300 and the robot 500 have high precision, and the error is less than or equal to 0.1 mm, so as to ensure the position accuracy of transmission and the assembly accuracy of the pins 1, which cannot be achieved manually.

[0039] Furthermore, the pressing fixture 400 has a placement state and a conveying state. The pressing fixture 400 can rotate relative to the moving module 300 to switch the pressing fixture 400 between the placement state and the conveying state. When the pressing fixture 400 is in the placement state, the pressing fixture 400 forms a preset angle with the horizontal direction. When the pressing fixture 400 is in the conveying state, the pressing fixture 400 is horizontally arranged. Specifically, before the pins 1 are installed and the buttons are locked, the buttons are likely to fall off. Therefore, in this application, before placing the product, the pressing fixture 400 is in the placement state, so that the pressing fixture 400 forms a preset angle with the horizontal direction, thereby preventing the buttons from falling off. After the pressing fixture 400 fixes the product and presses the buttons of the product, then rotate the pressing fixture 400 to switch the pressing fixture 400 to the conveying state, and then convey the product to the pin 1 installation position. When in the conveying state, the pressing fixture 400 is horizontally arranged, which is convenient for inserting the pins 1.

[0040] In this embodiment, the preset included angle is 45 degrees. In other embodiments, the preset included angle can also be greater than 45 degrees or less than 45 degrees, as long as it can ensure that the button will not fall off when the product is placed on the pressing fixture 400 in the placed state.

[0041] Reference Figure 2 and Figures 5-6 As shown in FIGS. 8 and 9, the number of the moving modules 300 is two, and the two moving modules 300 are arranged in parallel at intervals, and each moving module 300 is correspondingly provided with a pressing fixture 400. Specifically, the two moving modules 300 are provided so that the button automatic pinning mechanism 1 can work in two lines, and products can be placed on the pressing fixtures 400 on the two moving modules 300 respectively. The robot 500 alternately inserts pins 1 into the products fixed on the pressing fixtures 400 on the two moving modules 300, thereby improving work efficiency.

[0042] Reference Figures 3-4 As shown in FIGS. 10 and 11, the pin 1 is connected to a handle 2. The robot 500 is used to clamp the handle 2 at the discharge port 210 and move the handle 2 and the pin 1 to the pin installation position. The robot 500 is used to insert the pin 1 into the product and break the handle 2. Specifically, the setting of the handle 2 enables the robot 500 not to directly clamp the pin 1, so that the pin 1 can be reliably inserted into the product to lock the button, and then the handle 2 can be broken relative to the pin 1.

[0043] Reference Figure 2 and Figure 5 As shown in FIGS. 12 and 13, the button automatic pinning mechanism further includes a waste collection box 600. The waste collection box 600 is installed on the frame 100. The robot 500 is further used to move the broken handle 2 to the waste collection box 600 and place it in the waste collection box 600. Specifically, the waste collection box 600 is used to collect the handle 2 broken relative to the pin 1 to realize the recycling of waste products.

[0044] Reference Figure 2, the robotic arm 500 includes a first transmission structure 510, a frame 520, a second transmission structure 530, a third transmission structure 540, a rotating structure 550, and a gripper 560. The first transmission structure 510 is connected to the frame 520. The second transmission structure 530 is disposed on the frame 520. The third transmission structure 540 is disposed on the second transmission structure 530. The rotating structure 550 is disposed on the third transmission structure 540. The first transmission structure 510 is used to drive the frame 520 to move in a first direction. The second transmission structure 530 is used to drive the third transmission structure 540 to move in a second direction. The third transmission structure 540 is used to drive the rotating structure 550 to move in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. The rotating structure 550 is used to drive the gripper 560 to rotate. Specifically, the settings of the first transmission structure 510, the second transmission structure 530, and the third transmission structure 540 enable the gripper 560 to achieve three-dimensional movement. The setting of the rotating structure 550 enables the gripper 560 to rotate. Thus, after the robotic arm 500 inserts the bolt 1 into the product, the gripper 560 drives the handle 2 to rotate back and forth (or swing back and forth), thereby breaking the handle 2 relative to the bolt 1.

[0045] In this embodiment, the first transmission structure 510, the second transmission structure 530, and the third transmission structure 540 are all cylinders.

[0046] The key automatic bolt 1 mechanism further includes a discharging and flipping structure. The discharging and flipping structure is installed on the frame 100 and is used to flip the product. Specifically, flipping the product and changing the orientation of the product and then discharging it are for the convenience of the next process.

[0047] Reference Figure 2 , the key automatic bolt 1 mechanism further includes an electric control touch screen 800. The electric control touch screen 800 is vertically disposed on the frame 100. The electric control touch screen 800 is signal-connected to the vibrating disk 200, the moving module 300, the pressing fixture 400, and the robotic arm 500. The electric control touch screen 800 is used to control the operation of the key automatic bolt 1 mechanism. Specifically, the electric control touch screen 800 is used to implement parameter setting and action control. After setting the corresponding parameters, the key automatic bolt 1 mechanism can be controlled to achieve the assembly of the bolt 1. This application realizes automated operation, and the production capacity is 3 - 5 times that of manual labor. In this embodiment, the electric control touch screen 800 is also signal-connected to the discharging and flipping structure.

[0048] Reference Figure 2, the electric control touch screen 800 has a start button 810, a reset button 820, a pause button 830, a switching knob 840 and an emergency stop button 850. The switching knob 840 is used to switch the key automatic pinning mechanism 1 between the automatic state and the manual state. The start button 810 is used to control the start of the key automatic pinning mechanism 1. After all parameters are set and relevant preparations are completed, the start button 810 can be pressed to realize the automatic assembly of the pin 1. The pause button 830 is used to control the pause of the key automatic pinning mechanism 1. When it is temporarily necessary to stop, the pause button 830 can be pressed. The reset button 820 is used to control the reset of the key automatic pinning mechanism 1 to the initial position. The emergency stop button 850 is used to control the emergency braking of the key automatic pinning mechanism 1. In case of an emergency, the emergency stop button 850 can be pressed to stop the operation of the equipment and prevent accidental injuries.

[0049] Reference Figure 1 , a protective net 900 is provided around the frame 100 to enclose each structure of the key automatic pinning mechanism 1. Specifically, the vibrating disk 200, the moving module 300, the pressing fixture 400, the robot 500 and the discharging and flipping structure are all enclosed within the protective net 900.

[0050] Reference Figure 1 , the key automatic pinning mechanism further includes feet 1000, and the feet 1000 are arranged at the bottom of the frame 100.

[0051] Reference Figure 1 , the number of the feet 1000 is multiple. In this embodiment, the number of the feet 1000 is four, which are respectively arranged at the four corners of the bottom of the frame 100.

[0052] Reference Figure 1 , the key automatic pinning mechanism further includes runners 1100, and the runners 1100 are arranged at the bottom of the frame 100. The arrangement of the runners 1100 facilitates the transfer of the key automatic pinning mechanism.

[0053] Reference Figure 1 , the number of the runners 1100 is multiple. In this embodiment, the number of the runners 1100 is four, which are respectively arranged at the four corners of the bottom of the frame 100.

[0054] The working process of each structure of the key automatic pinning mechanism is as follows:

[0055] After the buttons of products such as mobile phones are installed, place the product on the pressing fixture 400 in the placement state. Then, the pressing fixture 400 fixes the product and presses the buttons of the product to prevent the buttons from falling off. Then, rotate the pressing fixture 400 to switch the pressing fixture 400 to the conveying state. The moving module 300 drives the pressing fixture 400 in the conveying state to move, so as to convey the product to the pin 1 installation position. At the same time, the vibrating disk 200 is used to vibrate the pin 1 into a preset direction and convey it to the discharge port 210. Then, the first transmission structure 510, the second transmission structure 530 and the third transmission structure 540 cooperate to realize the three-dimensional movement of the gripper 560, so that the gripper 560 clamps the handle 2 at the discharge port 210, and moves the handle 2 and the pin 1 to the pin installation position. Then, insert the pin 1 into the product located at the pin 1 installation position, so as to lock the buttons of the product. After the pin 1 is inserted into the product, the rotating structure 550 drives the gripper 560 to rotate, so as to drive the handle 2 to rotate back and forth (or swing back and forth), so as to break the handle 2 relative to the pin 1, thus completing the assembly of the pin 1. The first transmission structure 510, the second transmission structure 530 and the third transmission structure 540 cooperate to realize the three-dimensional movement of the gripper 560, so as to move the broken handle 2 to the waste collection box 600 and place it in the waste collection box 600, realizing the recycling of waste products. This application does not require manual assembly of the pin 1. The robotic arm 500 can ensure the precise assembly of the pin 1, will not scratch the product, can be assembled successfully at one time, and the assembly is fast and reliable.
