[0027] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0028] like Figures 1 to 3 As shown, this embodiment provides a loading mechanism, including a first linear drive assembly 11, a second linear drive assembly 12 and a clamping assembly 13. The first linear drive assembly 11 has a first movable platform 14, the second linear drive assembly 12 is mounted on the first movable platform 14, and the second linear drive assembly 12 has a second movable platform 15, and the second movable platform 15 is used to install the clamping assembly 13;

[0029] The movement direction of the first mobile platform 14 is perpendicular to the movement direction of the second mobile platform 15;

[0030] The clamping assembly 13 is provided with a plurality of first clamping members 16 .

[0031] This solution can achieve accurate feeding of products, with each first clamping member 16 on the clamping assembly 13 clamping one product respectively;

[0032] The first linear drive assembly 11 operates, and the first mobile platform 14 moves a specified distance, moving each product in the feed direction. Each first clamping member 16 then releases, and the second mobile platform 15 moves a specified distance away from the product to separate the first clamping member 16 from the product. The first mobile platform 14 then returns to its initial position in the opposite direction of the feed, and the second mobile platform 15 moves toward the product, with each first clamping member 16 gripping a product. This process is repeated to deliver each product individually.

[0033] This solution has the advantages of stable feeding and high distance control accuracy. In multiple pushes, the same pushing distance can be achieved each time for the product.

[0034] The loading mechanism in this solution can move multiple products the same distance after one operation, and then add a product at the input end of the loading mechanism, which can realize continuous loading of products, facilitate the delivery of products in sequence to multiple workstations, facilitate transportation, and improve product processing efficiency.

[0035] Furthermore, the movement direction of the first movable platform 14 is set along the X-axis direction; the movement direction of the second movable platform 15 is set along the Y-axis direction.

[0036] Furthermore, the first linear drive assembly 11 includes a first cylinder 19, which is mounted on the support platform 18 via a support. The first movable platform 14 is mounted on the support platform 18 via a first slide rail assembly 17. The first cylinder 19 is connected to the first movable platform 14 by screw threading or welding, and the first cylinder 19 is used to push the first movable platform 14. The second linear drive assembly 12 includes a second cylinder 20, which is mounted on the first movable platform 14 via a support. The second movable platform 15 is mounted on the first movable platform 14 via a second slide rail assembly 43. The second cylinder 20 and the second movable platform 15 are connected by screw threading or welding, and the second cylinder 20 is used to push the second movable platform 15.

[0037] Among the three or more first clamping members 16 , the distance between two adjacent first clamping members 16 is equal, and the distance of each extension and contraction of the first cylinder 19 is equal to the distance between the two adjacent first clamping members 16 .

[0038] In this solution, the first cylinder 19 and the second cylinder 20 can set the telescopic distance themselves, so that the position of the first clamping member 16 can be accurately controlled, thereby improving the loading accuracy.

[0039] In addition, a photoelectric switch may be provided on the supporting platform 18 to detect the position of the first movable platform 14 to improve the feeding accuracy.

[0040] As an implementation of this embodiment, a plurality of first clamping members 16 are arranged in a linear array along the X-axis direction.

[0041] In addition, if Figures 1 to 5 As shown, the present application also proposes a coupler press-fitting device for pressing the end cover 25 onto the coupler 21, comprising the above-mentioned feeding mechanism, and a first clamping member 16 for clamping the coupler 21;

[0042] It also includes a support platform 18, which is used to install the feeding mechanism.

[0043] Furthermore, a pre-installation mechanism 22 is included, and the pre-installation mechanism 22 includes:

[0044] A fixing plate 23, a pad is fixed to the lower end of the fixing plate 23, and the pad is fixed to the support platform 18 through a fixing rod 24;

[0045] A loading assembly is mounted on the support platform 18 and is used to place the end cap 25 on the upper end of the coupler 21;

[0046] The pre-pressing assembly 26 is mounted on the fixing plate 23 and is used to mount the end cover 25 on the coupler 21 .

[0047] The loading assembly includes a third mobile platform 27 and a drive assembly 28. The drive assembly 28 is mounted on the support platform 18 and is used to drive the third mobile platform 27. The end cap 25 is first placed on the third mobile platform 27. The drive assembly 28 is in the form of a rodless cylinder, a linear motor, or a motor-driven screw-slider mechanism. Each of these drive assemblies 28 has a moving portion for securing the third mobile platform 27.

[0048] The loading assembly also has a third clamping member 29. A vertical plate 30 is fixed to the support platform 18, and a rotary cylinder 31 is fixed to the vertical plate 30. The third clamping member 29 is fixed to the output end of the rotary cylinder 31. The third clamping member 29 is used to clamp the end cap 25 on the third movable platform 27. The rotary cylinder 31 then drives the third clamping member 29 to rotate 180 degrees to place the end cap 25 on the upper end of the coupler 21. The third clamping member 29 is then released and the rotary cylinder 31 drives the third clamping member 29 to return to its initial position.

[0049] The third clamping member 29 is eccentrically mounted on the output end of the rotary cylinder 31 to increase the delivery distance of the third clamping member 29 to the end cover 25 before and after turning 180°.

[0050] Furthermore, the third clamping member 29 includes a mounting plate 32, a third cylinder 33, a fourth cylinder 34, a first clamping arm 35, and a second clamping arm 36. The mounting plate 32 is fixed to the output end of the rotating cylinder 31, and the cylinder bodies of the third cylinder 33 and the fourth cylinder 34 are respectively fixed to the mounting plate 32.

[0051] The piston rods of the third and fourth cylinders 33, 34 extend and retract in parallel directions, and when extended, the piston rods of the third and fourth cylinders 33, 34 are both directed toward the side facing away from the first linear drive assembly 11. A first clamping arm 35 is fixed to the piston rod of the third cylinder 33, and a second clamping arm 36 is fixed to the piston rod of the fourth cylinder 34.

[0052] The installation form of the third cylinder 33, the fourth cylinder 34, the first clamping arm 35 and the second clamping arm 36 in this solution can increase the rotation radius of the first clamping arm 35 and the second clamping arm 36 and adapt to the delivery distance of the third clamping member 29 to the end cover 25.

[0053] Furthermore, the prestressing assembly 26 includes a linear motion mechanism 37, a vertical cylinder 38 and a prestressing column 39. The linear motion mechanism 37 is installed on the fixed plate 23, and the linear motion mechanism 37 has an output end that moves in a linear direction. A movable plate 44 is fixed on the output end of the linear motion mechanism 37. The movable plate 44 is used to fix the vertical cylinder 38. The vertical cylinder 38 has a telescopic rod that moves downward. The prestressing column 39 is fixed to the lower end of the telescopic rod of the vertical cylinder 38.

[0054] The linear motion mechanism 37 is in the form of a rodless cylinder, a linear motor or a motor-driven screw slider mechanism.

[0055] The linear motion mechanism 37 drives the position of the preload column 39, which is used to adjust the position. The vertical cylinder 38 drives the preload column 39 downward, and the preload column 39 presses the end cover 25 against the inner hole of the coupler 21. The lower end of the preload column 39 has a guide column, and the upper end of the guide column has a tapered surface, which uses the tapered surface to press the end cover 25 against the coupler 21.

[0056] Furthermore, a stripping mechanism is included, which has a second clamping member 40, and the second clamping member 40 is located above the coupler 21, for clamping the end cover 25 on the coupler 21. So that the pre-load column 39 can be detached from the end cover 25.

[0057] The stripping mechanism includes a Z-axis module 45, which is a slide cylinder in the prior art. The second clamping member 40 is fixed to the output end of the Z-axis module 45, and the Z-axis module 45 is mounted on the fixed plate 23. When the second clamping member 40 is detached from the end cover 25, the Z-axis module 45 is used to drive the second clamping member 40 to move upward to prevent the second clamping member 40 from blocking the end cover 25.

[0058] Furthermore, a press-fitting mechanism is included. The press-fitting mechanism has a press-fitting portion 41 that moves in a vertical direction and is used to press the end cover 25 onto the upper end of the coupler 21 .

[0059] The press-fitting mechanism's press-fitting station and the pre-pressing mechanism's pre-pressing station are located on a conveyor line for couplers 21. A loading mechanism is used to feed couplers 21 from the pre-pressing station onto the press-fitting mechanism one by one. The press-fitting mechanism includes a press-fitting cylinder 42, which has a downwardly movable piston column with a press-fitting unit 41 fixed to it. The press-fitting unit 41 presses the end cap 25 downward, tightly pressing the end cap 25 onto the coupler 21.

[0060] In addition, the first clamping member 16 and the second clamping member 40 in this solution are prior art. They can directly adopt the prior art clamping cylinder, or they can be installed on the basis of the clamping cylinder.
