DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] Example 1 This embodiment provides a production station for automatic riveting and fastening. Figure 1 As shown, it includes a loading and unloading module 1, a robot module 2, a double-sided riveting module 3 and a locking module 4.

[0020] Specifically, the loading and unloading module 1 is provided with a material box 5, and the loading and unloading module 1 is used to lift and transfer the material box 5. The robot module 2 cooperates with the loading and unloading module 1, the double-sided riveting module 3 and the locking module 4, and is used to grab and transfer the material 6 in the loading and unloading module 1, the double-sided riveting module 3 and the locking module 4. The double-sided riveting module 3 is used to perform double-sided riveting on the material 6. The locking module 4 is used to lock the riveted material 6.

[0021] like Figure 3 As shown, the double-sided riveting module 3 includes a mobile platform 3-1, a positive riveting mechanism, a negative riveting mechanism, a first identification unit 3-4, a positioning unit 3-7 and a third control unit. The positioning unit 3-7 is used to locate the material 6 grasped by the robot module 2. The mobile platform 3-1 is used to carry the material 6 and move the material 6 to the riveting position. The first identification unit 3-4 is connected to the third control unit, which is used to identify the position of the mobile platform 3-1 and send the position information of the mobile platform 3-1 to the third control unit. The third control unit is used to control the mobile platform 3-1 to move to the riveting position according to the received position information. The positive riveting mechanism is used to perform positive riveting on the material 6, and the negative riveting mechanism is used to perform negative riveting on the material 6.

[0022] In this embodiment, the first recognition unit 3 - 4 uses a photosensitive coupling device CCD camera.

[0023] In this embodiment, the loading and unloading module 1, the robot module 2, the double-sided riveting module 3 and the locking module 4 are all independent modules, which can work independently or in combination. Through different combinations, a series of standardized work stations such as riveting + locking, riveting + riveting, locking + locking are formed to realize automatic loading and unloading, automatic double-sided riveting and automatic locking.

[0024] Working principle: The robot module 2 takes the material from the material box 5 on the loading and unloading module 1, places it in the positioning unit 3-7 for secondary positioning, takes two pieces of the secondary positioned material 6 and moves to the mobile platform 3-1. After the first recognition unit 3-4 recognizes and calculates, the mobile platform 3-1 moves to the positive riveting mechanism for positive riveting, and then moves to the reverse riveting mechanism for reverse riveting. After the riveting is completed, the robot module 2 takes the riveted material 6 and moves it to the locking module 4 for locking.

[0025] Example 2 This embodiment provides an implementation method of each module based on Embodiment 1.

[0026] like Figure 2 As shown, the loading and unloading module 1 includes a material receiving mechanism 1-1, a transfer mechanism 1-2, a material unloading mechanism 1-3, a lifting mechanism 1-4 and a first control unit.

[0027] Specifically, the receiving mechanism 1-1 is provided with a conveyor belt for carrying and transporting the material box 5, and the lifting mechanism 1-4 cooperates with the receiving mechanism 1-1 to lift and lower the material box 5. The transfer mechanism 1-2 is used to transfer the material box 5 to the unloading mechanism 1-3, and the unloading mechanism 1-3 is provided with a conveyor belt for transporting the material box 5 to the unloading port.

[0028] In this embodiment, the material receiving mechanism 1-1 and the material unloading mechanism 1-3 are both provided with conveyor belts, which can be directly connected to an automatic guided vehicle to realize material receiving and material feeding, thereby improving the degree of automation.

[0029] In this embodiment, the first control unit adopts a PLC system, which automatically lifts and transfers the material box 5 according to the control program, so as to realize automatic material replenishment, automatic transfer and automatic unloading of the tooling material box 5.

[0030] like Figure 1 As shown, the robot module 2 includes a robot body 2-1 and a robot end 2-2.

[0031] Specifically, the robot body 2-1 is connected to the robot end 2-2, and the operation of the robot end 2-2 is controlled by the second control unit. The robot end 2-2 is used to suck the material 6 in the material box 5, transfer the material 6 for riveting and locking, and place the finished product in the material box 5.

[0032] In this embodiment, the robot end 2 - 2 adopts a double-station material suction method, which can suck the riveted material 6 on one side and rotate 180° to re-insert the material 6 to be riveted.

[0033] In this embodiment, a sensing unit is provided at the robot end 2-2 to detect the air pressure of the suction nozzle in real time to realize material drop identification.

[0034] like Figure 3 and 4 As shown, the lower end of the mobile platform 3-1 is slidably connected to the slide rail, and the movement of the mobile platform 3-1 on the slide rail is controlled by the third control unit, thereby controlling the movement of the mobile platform 3-1 in the plane. The mobile platform 3-1 includes a floating platform 3-1-1, a first cylinder 3-1-2, a positioning member 3-1-3, a motor 3-1-4 and a second cylinder 3-1-5.

[0035] Specifically, the positioning member 3-1-3 is provided on the floating platform 3-1-1 and is used to position the material 6. The first cylinder 3-1-2 is provided on one side of the positioning member 3-1-3 and is used to fix the material 6 on the positioning member 3-1-3. The motor 3-1-4 is provided on one side of the floating platform 3-1-1 and is used to drive the floating platform 3-1-1 to rotate. The second cylinder 3-1-5 is used to lift the floating platform 3-1-1.

[0036] In this embodiment, the floating platform 3-1-1 adopts an elastic platform to offset the relative displacement in the vertical direction during the riveting process.

[0037] like Figure 1 As shown, the positive riveting mechanism includes a positive riveting unit 3-2 and a positive feeding unit 3-5. The positive feeding unit 3-5 is used to transport the screw sleeve to the front of the material 6, and the positive riveting unit 3-2 is used for riveting the screw sleeve and the front of the material 6.

[0038] like Figure 5 As shown, the positive feeding unit 3-5 includes a first vibration plate 3-5-1, a first upper pushing mechanism 3-5-2, a first feeding pipe 3-5-3, a first lower pushing mechanism 3-5-4, a supporting mechanism 3-5-5 and a suction riveting mechanism 3-5-6.

[0039] Specifically, the first vibration disk 3-5-1 is connected to the first upper pushing mechanism 3-5-2, and is used to transport the screw sleeve to the first upper pushing mechanism 3-5-2. The first upper pushing mechanism 3-5-2, the first feeding pipe 3-5-3 and the first lower pushing mechanism 3-5-4 are connected in sequence, and the first upper pushing mechanism 3-5-2 pushes the screw sleeve to the mouth of the first feeding pipe 3-5-3, and transports the screw sleeve to the first lower pushing mechanism 3-5-4 by blowing air into the first feeding pipe 3-5-3. The first lower pushing mechanism 3-5-4 is used to push the screw sleeve to the supporting mechanism 3-5-5. The suction riveting mechanism 3-5-6 is located above the supporting mechanism 3-5-5, and fixes the screw sleeve to the pressure head of the suction riveting mechanism 3-5-6 by suction.

[0040] Working principle of positive feeding unit 3-5: The first vibration plate 3-5-1 vibrates the screw sleeve and sends it to the first upper push mechanism 3-5-2. When the sensing system senses that there is no material at the first feeding pipe 3-5-3, the cylinder in the first upper push mechanism 3-5-2 pushes the material to the first feeding pipe 3-5-3 for standby use. After receiving the front-end signal, blow air into the first feeding pipe 3-5-3 to send the screw sleeve to the first lower push mechanism 3-5-4. The cylinder in the first lower push mechanism 3-5-4 pushes the screw sleeve to the supporting mechanism 3-5-5. After the material 6 is in place, the suction riveting mechanism 3-5-6 fixes the screw sleeve to the pressure head of the suction riveting mechanism 3-5-6 by suction, and the pressure head moves downward for riveting. The supporting mechanism 3-5-5 uses a movable shutter structure for avoidance.

[0041] like Figure 1 As shown, the reverse riveting mechanism includes a reverse riveting unit 3-3 and a reverse feeding unit 3-6. The reverse feeding unit 3-6 is used to transport the screw sleeve to the reverse side of the material 6, and the reverse riveting unit 3-3 is used for riveting the screw sleeve and the reverse side of the material 6.

[0042] like Figure 6 As shown, the reverse feeding unit 3-6 includes a second vibration plate 3-6-1, a second upper pushing mechanism 3-6-2, a second feeding tube 3-6-3, a second lower pushing mechanism 3-6-4, a top feeding mechanism 3-6-5 and a riveting mechanism 3-6-6.

[0043] Specifically, the second vibration plate 3-6-1 is connected to the second upper pushing mechanism 3-6-2, and is used to transport the hexagonal bolts to the second upper pushing mechanism 3-6-2. The second upper pushing mechanism 3-6-2, the second feeding pipe 3-6-3 and the second lower pushing mechanism 3-6-4 are connected in sequence, and the second upper pushing mechanism 3-6-2 pushes the hexagonal bolts to the mouth of the second feeding pipe 3-6-3, and transports the hexagonal bolts to the second lower pushing mechanism 3-6-4 by blowing air into the second feeding pipe 3-6-3. The pushing mechanism 3-6-5 is flush with the upper end of the riveting mechanism 3-6-6, and is used to cooperate with the second lower pushing mechanism 3-6-4 to push the hexagonal bolts to the riveting mechanism 3-6-6.

[0044] Working principle of reverse feeding unit 3-6: The second vibration plate 3-6-1 sends the hexagonal bolt to the second upper push mechanism 3-6-2. When the sensing system senses that there is no material at the second feeding tube 3-6-3, the second upper push mechanism 3-6-2 pushes the hexagonal bolt to the second feeding tube 3-6-3 for standby use. After receiving the front-end signal, blow air into the second feeding tube 3-6-3 to send the hexagonal bolt to the second lower push mechanism 3-6-4. The second lower push mechanism 3-6-4 pushes the hexagonal bolt and pushes the hexagonal bolt to the upper end of the riveting mechanism 3-6-6 through the push mechanism 3-6-5. Then the push mechanism 3-6-5 descends, and the hexagonal bolt stays in the riveting mechanism 3-6-6 to prepare for riveting. After the riveting of material 6 is completed, the push mechanism 3-6-5 returns to its position.

[0045] like Figure 7 and 8 As shown, the locking module 4 includes a transfer platform 4-1, a locking unit 4-2 and a nail feeding unit 4-3.

[0046] Specifically, the transfer platform 4-1 is used to carry and transfer the riveted material 6. The nail feeding unit 4-3 is used to deliver screws to the riveted material 6. The locking unit 4-2 is used to lock the screws and the riveted material 6.

[0047] Furthermore, a servo module 4-2-1 is provided around the locking unit 4-2, and the servo module 4-2-1 is used for moving the locking unit 4-2. The locking unit 4-2 includes a second identification unit 4-2-2 and a servo electric screwdriver 4-2-3. The second identification unit 4-2-2 is used to identify the position of the transfer platform 4-1 and assist the transfer platform 4-1 to move to the locking position. The servo electric screwdriver 4-2-3 is used for locking.

[0048] In this embodiment, the transfer platform 4-1 uses a linear guide rail to achieve movement. The second recognition unit 4-2-2 uses a photosensitive coupling device CCD camera.

[0049] Working principle: The material 6 is placed in the material box 5, and the material box 5 is placed on the receiving module 1-1 by an automatic guided vehicle or manually, and is sent to the lifting position of the receiving module 1-1 by a conveyor belt. The lifting mechanism 1-4 drives the lifting position to drive the material box 5 to lift to the working position. The robot body 2-1 uses the second control unit to control the robot end 2-2 to suck two pieces of material 6 from the material box 5, and detects the suction nozzle air pressure in real time to realize the material drop identification. After identification, it is placed in the positioning unit 3-7 for secondary positioning, and after positioning, the material 6 is sucked again and moved to the mobile platform 3-1. The material 6 is placed on the positioning piece 3-1-3, and the first cylinder 3-1-2 automatically clamps the material 6. After the first identification unit 3-4 performs identification calculation, the third control unit controls the mobile platform 3-1 to move and rotate in the plane respectively until it reaches the riveting position. The positive feeding unit 3-5 feeds up, the front riveting unit 3-2 completes the front riveting, the reverse feeding unit 3-6 feeds down, and the reverse riveting unit 3-4 completes the reverse riveting. After the riveting is completed, the first cylinder 3-1-2 is automatically released. The robot body 2-1 controls the robot end 2-2 to absorb the riveted material 6 in the mobile platform 3-1, and puts the material 6 to be riveted after rotation. The robot body 2-1 controls the robot end 2-2 to move to the transfer platform 4-1 of the locking module 4, absorbs two pieces of riveted materials 6, and rotates the robot end 2-2 to place the riveted materials 6 to be locked on the transfer platform 4-1. The transfer platform 4-1 moves to the working position, the servo module 4-2-1 realizes the movement of the locking unit 4-2 in the horizontal and vertical directions, and the second recognition unit 4-2-2 calculates the distance error. The nail feeding unit 4-3 is responsible for automatic nail feeding, and the servo electric screwdriver 4-2-3 performs the locking action to realize automatic locking. The robot body 2-1 controls the robot end 2-2 to absorb the locked material 6 in the transfer platform 4-1 of the locking module 4, and puts the material 6 to be locked at the same time. The robot body 2-1 controls the robot end 2-2 to move to the loading and unloading module 1, puts the finished product into the material box 5, and simultaneously sucks and replaces the processed material 6. After all the materials 6 in the material box 5 are processed, the material box 5 is moved to the lowering position by the transfer mechanism 1-2, lowered to the conveyor belt of the unloading mechanism 1-3 through the lifting mechanism 1-4, and sent to the unloading port, and unloading is completed by manual or automatic guided vehicle.
