DETAILED DESCRIPTION

[0018] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.

[0019] See also Figure 1-Figure 5 The utility model provides a clamping product assembly mechanism, comprising:

[0020] The positioning and clamping mechanism includes a base plate 3, a guide rail 4 is provided on the base plate 3, a fixing member 6 is fixedly provided on one side of the base plate 3, and a clamping plate 5 is provided on the other side. The clamping plate 5 is movably engaged with the base plate 3 through the guide rail 4. The fixing member 6 is used to accommodate the product head 1 and form a limit.

[0021] A first positioning fixture 7 is provided on the side of the fixture plate 5 away from the fixing part 6, and a second positioning fixture 8 is provided on the side of the fixture plate 5 close to the fixing part 6. The first positioning fixture 7 is used to clamp the product body 2 and move along with the fixture plate 5 on the guide rail 4. The second positioning fixture 8 is used to limit the positioning of the end of the product body 2. When loading, the second positioning fixture 8 is closed, and a accommodating space is generated after the second positioning fixture 8 is closed. The accommodating space is matched with the end shape of the product body 2, so that the product body 2 can be accurately positioned at the specified position during loading. During assembly, the second positioning fixture 8 is opened, and when the fixture plate 5 moves on the guide rail 4, the opened second positioning fixture 8 forms a avoidance with the product head 1 in the fixing part 6.

[0022] The assembly line also includes several workstations, including a product assembly station 14-2. This station 14-2 includes an L-shaped assembly arm. A first cylinder 12 is mounted on the vertical arm of the assembly arm, facing the positioning and clamping mechanism. A second cylinder 13 is mounted on the horizontal arm of the assembly arm, facing the positioning and clamping mechanism. The first cylinder 12 is used to push the fixture plate 5 along the guide rail 4, and the second cylinder 13 is used to cooperate with the fixing member 6 to limit and fix the product head 1.

[0023] The fixing member 6 is also provided with a guide roller 9 extending in the direction of the guide rail 4, and the clamp plate 5 is also provided with a guide roller sleeve 10. The guide roller sleeve 10 is in limited sliding cooperation with the guide roller 9. The guide roller 9 is also sleeved with a spring 11. One end of the spring 11 abuts against the side of the fixing member 6 facing the guide roller sleeve 10, and the other end abuts against the side of the guide roller sleeve 10 facing the fixing member 6. The spring 11 is compressed when the first cylinder 12 pushes the clamp plate 4 toward the fixing member 6, accumulating elastic potential energy. When the first cylinder 12 retreats and releases the force on the clamp plate 4, the elastic potential energy of the spring 11 is released, pushing the guide roller sleeve 10 to move along the guide roller 9 away from the fixing member 6. The clamp plate 5 fixedly connected to the guide roller sleeve 10 can also move along the guide rail 4 away from the fixing member 6, thereby realizing the reset of the positioning clamping mechanism after assembly is completed.

[0024] Example 1:

[0025] In this embodiment, a turntable 1 is used as a device for the circulation of multiple workstations. A motor 16 is provided at the bottom of the turntable 15 , and the rotating shaft of the motor 16 is provided at the center of the turntable 1 .

[0026] The plurality of workstations also include a product body loading station 14, a product head loading station 14-1, a product assembly station 14-2, and a product unloading station 14-3. These stations are centrally symmetrically arranged around the center of the turntable 15 and are sequentially distributed on the turntable 15. Each station is equipped with a plurality of positioning and clamping mechanisms, which are connected to the turntable 15 via hooks 17.

[0027] The product body loading station 14, the product head loading station 14-1 and the product unloading station 14-3 are also provided with several manipulators, which include slide rails, chains, clamping cylinders and clamping parts. The manipulators are used to load the product head 1 and the product body 2 and unload the assembled products.

[0028] The specific working principle is as follows:

[0029] At the product body loading station 14, the robot first places the product body 2 in the center of the fixture plate 4. At this time, the second positioning fixture 8 is closed to form a accommodating chamber with one end closed. The accommodating chamber allows the robot to fully abut the end of the product body 2 to form a precise positioning. Then the first positioning fixture 7 is closed to achieve clamping of the product body 2.

[0030] The motor 16 drives the turntable 15 to rotate, so that the positioning and clamping mechanism for loading the product body 2 enters the product head loading station 14-1. At this time, the manipulator places the product head 1 in the fixing member 6 to realize loading of the product head 1.

[0031] The motor 16 drives the turntable 15 to rotate, so that the positioning and clamping mechanism that has completed the loading of the product head 1 enters the product assembly station 14-2. At this time, the second positioning fixture 8 is opened, releasing the limit on the end of the product body 2. The second cylinder 13 is pushed out and cooperates with the fixing part 6 to fully fix the product head 1 in the fixing part 6. The first cylinder 12 is pushed out, pushing the clamp plate 5 to move along the guide rail 4 toward the fixing part 6. At this time, since the second positioning fixture 8 is opened, the second positioning fixture 8 and the product head 1 extending from the fixing part 6 form a avoidance, so that the product body 2 is clamped and driven to move, and the product body 2 and the product head 1 are assembled and matched. After the assembly is completed, the first positioning fixture 7 is opened to release the clamping of the product body 2. At this time, since the product head 1 and the product body 2 have been assembled into an integral product, and the product head 1 is now limited in the fixing part 6, the positioning and clamping mechanism can still achieve the limitation of the product.

[0032] After the product assembly is completed, the first cylinder 12 and the second cylinder 13 are both retracted. At this time, the spring 11, which was originally compressed on the guide roller 9 with the movement of the clamp plate 5, can release the accumulated elastic potential energy, pushing the guide roller sleeve 10 along the guide roller 9 to return to the original position, that is, pushing the clamp plate 5 fixedly connected to the guide roller sleeve 10 back to the original position along the guide rail 4.

[0033] Motor 16 drives turntable 15 to rotate, allowing the assembled product positioning and clamping mechanism to enter product unloading station 14-3. The robot removes the assembled product. At this point, since only the two sides of the product head 1 are restrained and the bottom is supported, the product can be removed by simply lifting it vertically upward to avoid the fixing member 6 and successfully remove the product.

[0034] The motor 16 drives the turntable 15 to rotate, so that the empty positioning and clamping mechanism with the product taken out re-enters the product body loading station 14 to start the next round of automated assembly operation.

[0035] The above description is only a specific implementation method of this utility model, but the protection scope of this utility model is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by this utility model, can make equivalent substitutions or changes based on the technical solutions and new concepts of this utility model, which should be covered by the protection scope of this utility model.
