[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides a U-shaped buckle precision assembly mechanism 100, which includes a limiting component 110 and a pushing component 120. The limiting component 110 includes a limiting plate 111, and the limiting plate 111 includes a limiting portion 1111. The U-shaped buckle 200 is clamped on the limiting portion 1111 and the opening is aligned with the part to be assembled; the pushing component 120 includes a follower plate 121, and the follower plate 121 can move along a first plane a to approach or move away from the part to be assembled; the limiting plate 111 can move along a second plane b to approach or move away from the follower plate 121; the limiting plate 111 moves along the second plane b toward a direction away from the follower plate 121 to release the limitation of the U-shaped buckle 200, and the follower plate 121 moves along the first plane a and pushes the U-shaped buckle 200 to drive the U-shaped buckle 200 to assemble with the part to be assembled.

[0034] Specifically, the U-shaped buckle precision assembly mechanism 100 includes a limiting assembly 110 and a pushing assembly 120. The limiting assembly 110 includes a limiting plate 111, the plate surface of which is arranged parallel to the first plane a, and the U-shaped buckle 200 can be clamped on the limiting portion 1111 of the limiting plate 111, and the limiting portion 1111 can limit the opening direction of the U-shaped buckle 200, so that the opening of the U-shaped buckle 200 always faces the part to be assembled and is aligned with the part to be assembled. The follower plate 121 can move along the second plane b to approach or move away from the pushing assembly 120, and adjust the relative position with the pushing assembly 120.

[0035] The pushing assembly 120 includes a follower plate 121, which can move along the first plane a to approach or move away from the part to be assembled. The movement direction of the follower plate 121 is the same as the opening direction of the U-shaped buckle 200. During the movement, the follower plate 121 can abut against the side of the U-shaped buckle 200 arranged on the pushing plate away from the opening.

[0036] The follower plate 121 moves along the second plane b in a direction away from the follower plate 121, and at the same time, the follower plate 121 moves along the first plane a to push the U-shaped buckle 200. At this time, the U-shaped buckle 200 is separated from the limiting plate 111 and is pushed by the follower plate 121 along the first direction c until the U-shaped buckle 200 is assembled with the part to be assembled.

[0037] Although the existing U-shaped buckle assembly mechanism can push the U-shaped buckle to make it snap-fit ​​and assemble with the part to be assembled, it is unable to limit the opening direction of the U-shaped buckle during the snap-fit ​​process. During the pushing process, it is also difficult to avoid the opening direction of the U-shaped buckle from being offset, which reduces the assembly accuracy of the U-shaped buckle and the part to be assembled. The U-shaped buckle precision assembly mechanism 100 provided in the present application ensures the limit fixation of the opening direction of the U-shaped buckle 200 through the cooperation of the limiting component 110 and the pushing component 120. During the pushing process of the U-shaped buckle 200, the possibility of the opening direction of the U-shaped buckle 200 being offset is also reduced, thereby improving the assembly accuracy of the U-shaped buckle 200 and the part to be assembled.

[0038] It should be noted that, in one possible implementation of the present application, Figure 2 As shown, first, the pushing component 120 includes a two-stage assembly cylinder 122, and the two-stage assembly cylinder 122 includes a movably arranged first sliding portion 1221, and the first sliding portion 1221 is fixedly connected to the follower plate 121, and the first sliding portion 1221 can make a linear reciprocating motion along the first plane a relative to the cylinder body of the two-stage assembly cylinder 122 to drive the follower plate 121 to approach or move away from the part to be assembled; the first plane a and the second plane b are perpendicular to each other.

[0039] Specifically, the push assembly 120 includes a two-stage assembly cylinder 122, and the follower plate 121 is fixedly connected to the first sliding portion 1221 of the two-stage assembly cylinder 122. The first sliding portion 1221 can drive the follower plate 121 to perform linear reciprocating motion along the first plane a relative to the cylinder body of the two-stage assembly cylinder 122, so that the follower plate 121 is close to or away from the part to be assembled. The first plane a and the second plane b are perpendicular to each other, so that the follower plate 121 moves in the horizontal direction relative to the part to be assembled, and the limit plate 111 moves in the vertical direction relative to the part to be assembled.

[0040] The setting of the two-stage assembly cylinder 122 can make the process of the follower plate 121 moving along the first plane a more efficient and stable, thereby improving the assembly efficiency and reliability of the U-shaped buckle precision assembly mechanism 100.

[0041] Second, if Figure 3As shown, the limiting assembly 110 includes a lifting cylinder 112, and the lifting cylinder 112 includes a movably arranged second sliding portion 1121, and the second sliding portion 1121 is fixedly connected to the limiting plate 111, and the second sliding portion 1121 can make a linear reciprocating motion along the second plane b relative to the cylinder body of the lifting cylinder 112 to drive the limiting plate 111 to move along the second plane b to approach or move away from the follower plate 121.

[0042] Specifically, the limiting assembly 110 includes a lifting cylinder 112, and the limiting plate 111 is fixedly connected to the second sliding portion 1121 of the lifting cylinder 112. The second sliding portion 1121 can drive the limiting plate 111 to perform linear reciprocating motion along the second plane b relative to the cylinder body of the lifting cylinder 112, so that the lifting cylinder 112 approaches or moves away from the follower plate 121, and then adjusts the relative position between the U-shaped buckle 200, the follower plate 121 and the part to be assembled, so that the follower plate 121 can accurately push the U-shaped buckle 200 to assemble with the part to be assembled.

[0043] The provision of the lifting cylinder 112 can make the process of the limiting plate 111 moving along the second plane b more efficient and stable, thereby improving the assembly efficiency and reliability of the U-shaped buckle precision assembly mechanism 100.

[0044] The present application provides a U-shaped buckle precision assembly mechanism 100, which includes a limiting component 110 and a pushing component 120. The limiting component 110 includes a limiting plate 111, and the limiting plate 111 includes a limiting portion 1111. The U-shaped buckle 200 is clamped on the limiting portion 1111 and the opening is aligned with the part to be assembled to limit and fix the opening direction of the U-shaped buckle 200; the pushing component 120 includes a follower plate 121, and the follower plate 121 can move along a first plane a to approach or move away from the part to be assembled; the limiting plate 111 can move along a second plane b to approach or move away from the follower plate 121; the limiting plate 111 moves along the second plane b toward and away from the follower plate The U-shaped buckle 200 moves in the direction of 121 to release the limit on the U-shaped buckle 200, and the follower plate 121 moves along the first plane a and pushes the U-shaped buckle 200 to drive the U-shaped buckle 200 to be assembled with the part to be assembled. Through the cooperation between the limiting component 110 and the pushing component 120, it is ensured that during the assembly process of the U-shaped buckle 200 with the part to be assembled, the opening direction of the U-shaped buckle 200 is always aligned with the part to be assembled without deviation, thereby improving the accuracy of the assembly position of the U-shaped buckle 200 and the part to be assembled; at the same time, the pushing component 120 can ensure that the U-shaped buckle 200 is pushed to be fully engaged with the part to be assembled, thereby improving the success rate of product assembly.

[0045] For example, Figure 4As shown, the follower plate 121 includes a fixed portion 1211 and a pushing portion 1212 connected to each other. The fixed portion 1211 is fixedly connected to the first sliding portion 1221. The first sliding portion 1221 can drive the fixed portion 1211 to move along the first plane a until the pushing portion 1212 extends out from the edge of the cylinder body of the two-stage assembly cylinder 122.

[0046] Specifically, the follower plate 121 includes a fixing portion 1211 and a pushing portion 1212, the fixing portion 1211 being used to be fixedly connected to the first sliding portion 1221 of the two-stage assembly cylinder 122 to achieve a stable connection between the follower plate 121 and the two-stage assembly cylinder 122; the first sliding portion 1221 drives the fixing portion 1211 and the pushing portion 1212 to move along the first plane a to approach the part to be assembled, until the pushing portion 1212 extends out of the edge of the cylinder body of the two-stage assembly cylinder 122, so as to ensure that the follower plate 121 can abut against the end of the U-shaped buckle 200 facing away from the outlet through the pushing portion 1212, so as to ensure that the U-shaped buckle 200 is pushed to be fully engaged with the part to be assembled, thereby improving the success rate of product assembly.

[0047] In one possible implementation of the present application, Figure 4 As shown, the pushing portion 1212 has a plurality of slots, the setting direction of the slots is in the same direction as the movement direction of the first sliding portion 1221, and the plurality of slots are arranged in a straight line along the first direction c, and the first direction c is perpendicular to the movement direction of the first sliding portion 1221; one end of the slot is connected to the outside; a push rod 1213 is arranged in the slot, one end of the push rod 1213 can extend to the outside for pushing the U-shaped buckle 200 arranged on the limiting plate 111, and the other end is fixedly connected to the slot.

[0048] Specifically, Figure 4 As shown, the push part 1212 has a plurality of slots, the setting direction of the slots is the same as the movement direction of the first sliding part 1221, and one end of the slots is connected to the outside; a push rod 1213 is arranged in the slot, one end of the push rod 1213 can extend to the outside, and the other end is fixedly connected to the slot. Through such a setting, the push part 1212 can abut against the end of the U-shaped buckle 200 away from the opening through the push rod 1213, and the setting of the push rod 1213 can push the U-shaped buckle 200 to be fully engaged with the part to be assembled, thereby improving the success rate of product assembly.

[0049] like Figure 4 As shown, a plurality of slots are arranged in a straight line along a first direction c, and the first direction c is perpendicular to the movement direction of the first sliding portion 1221, so that the push rod 1213 arranged in the slot can correspond one-to-one with the position and setting quantity of the U-shaped buckle 200 on the limiting plate 111, thereby further improving the assembly efficiency of the U-shaped buckle precision assembly mechanism 100.

[0050] In one possible implementation of the present application, Figure 5 As shown, the limiting portion 1111 includes a base 1111 a and a protrusion 1111 b . The base 1111 a is disposed at the edge of the limiting plate 111 , and the protrusion 1111 b is disposed on a side of the base 1111 a close to the follower plate 121 .

[0051] Specifically, the limiting portion 1111 includes a base 1111a and a protrusion 1111b. The base 1111a is protruded from the surface of the limiting plate 111 to support the U-shaped buckle 200. The base 1111a is also protruded with a protrusion 1111b. The protrusion 1111b can be clamped at the opening of the U-shaped buckle 200 to limit the opening direction of the U-shaped buckle 200, thereby improving the assembly accuracy of the U-shaped buckle precision assembly mechanism 100.

[0052] For example, Figure 5 As shown, the limiting parts 1111 include multiple limiting parts 1111, which are arranged in a straight line on the limiting plate 111 along the first direction c and are located on one side edge of the limiting plate 111 close to the part to be assembled; the position and number of the limiting parts 1111 and the push rods 1213 correspond one to one.

[0053] Specifically, the limiting parts 1111 include a plurality of limiting parts 1111, which are arranged in a straight line on the limiting plate 111 along the first direction c, so as to correspond to the position and number of the push rods 1213 one by one, thereby improving the assembly efficiency of the U-shaped buckle precision assembly mechanism 100. The plurality of limiting plates 111 are arranged on one side edge of the limiting plate 111 close to the part to be assembled, thereby reducing the relative distance between the U-shaped buckle 200 and the part to be assembled, thereby reducing the possibility of the opening direction of the U-shaped buckle 200 being offset during the assembly process of the U-shaped buckle 200 and the part to be assembled, and further improving the accuracy of the assembly position of the U-shaped buckle 200 and the part to be assembled.

[0054] It should be noted that in one possible implementation of the present application, the side of the limiting portion 1111 facing away from the part to be assembled is an arcuate surface, and the side close to the part to be assembled is a plane, and the U-shaped buckle 200 is used to engage with the arcuate surface of the limiting portion 1111.

[0055] Since the inner wall of the U-shaped buckle 200 is a U-shaped structure, it can be well snap-fitted with the arc surface of the limiting part 1111, thereby achieving a better limiting and fixing effect; at the same time, the arc surface of the limiting part 1111 can achieve a good fit with the inner wall of the U-shaped buckle 200 without easily causing wear to the U-shaped buckle 200.

[0056] For example, Figure 6As shown, the U-shaped clip precision assembly mechanism 100 also includes a bracket 130, and the bracket 130 includes a first mounting plate 131, a second mounting plate 132 and a support column 133; the first mounting plate 131 and the second mounting plate 132 are arranged relatively spaced apart, and the two ends of the support column 133 are respectively fixedly connected to the first mounting plate 131 and the second mounting plate 132, and the plate surface of the first mounting plate 131 is smaller than the plate surface of the second mounting plate 132; the pushing component 120 is arranged on a side of the first mounting plate 131 away from the second mounting plate 132; the limiting component 110 is arranged on the second mounting plate 132 and is located outside the projection range of the first mounting plate 131 on the second mounting plate 132.

[0057] Specifically, the U-shaped buckle precision assembly mechanism 100 further includes a bracket 130, and the bracket 130 includes a first mounting plate 131, a second mounting plate 132, and a support column 133 disposed between the first mounting plate 131 and the second mounting plate 132. The plate surfaces of the first mounting plate 131 and the second mounting plate 132 are respectively parallel to the first plane a. The pushing assembly 120 is disposed on a side of the first mounting plate 131 away from the second mounting plate 132, so that the two-stage assembly cylinder 122 is disposed on the plate surface of the first mounting plate 131.

[0058] The limit assembly 110 is arranged on the second mounting plate 132. In order to make the limit plate 111 located at the edge of the cylinder body of the two-stage assembly cylinder 122 of the pushing assembly 120, the plate surface of the first mounting plate 131 is smaller than the plate surface of the second mounting plate 132. The limit assembly 110 is arranged in an area outside the projection range of the first mounting plate 131 on the second mounting plate 132 to ensure that when the lifting cylinder 112 of the limit assembly 110 drives the limit plate 111 to move up and down along the second plane b, its movement range will not be limited by the first mounting plate 131.

[0059] For example, Figure 6 As shown, the U-shaped buckle precision assembly mechanism 100 also includes a connecting block 140, which is arranged on the second mounting plate 132 and is located outside the projection range of the first mounting plate 131 on the second mounting plate 132, and the limiting component 110 is arranged on the side of the connecting block 140 away from the second mounting plate 132.

[0060] Specifically, a connecting block 140 is further provided on the second mounting plate 132, and the position limiting assembly 110 is provided on the connecting block 140, and the connecting block 140 can provide a certain supporting force for the position limiting assembly 110. The connecting block 140 is provided in an area outside the projection range of the first mounting plate 131 and the second mounting plate 132, so as to ensure that when the lifting cylinder 112 of the position limiting assembly 110 drives the position limiting plate 111 to move up and down along the second plane b, its movement range will not be limited by the first mounting plate 131.

[0061] In one possible implementation of the present application, Figure 6 As shown, the U-shaped clip precision assembly mechanism 100 also includes a moving cylinder 150, which is slidably provided with a third sliding part 151, and the third sliding part 151 can move along the extension direction of the moving cylinder 150; the bracket 130 is fixedly connected to the third sliding part 151 through the second mounting plate 132, and the moving cylinder 150 can drive the bracket 130 to reciprocate along the second plane b relative to the cylinder of the moving cylinder 150.

[0062] Specifically, the U-shaped clip precision assembly mechanism 100 also includes a moving cylinder 150, and the bracket 130 is arranged above the moving cylinder 150. The moving cylinder 150 includes a third sliding part 151 that can reciprocate along its cylinder body. The bracket 130 is fixedly connected to the third sliding part 151 through a second mounting plate 132, so that the moving bracket 130 drives the limiting assembly 110 and the pushing assembly 120 to move along the first plane a through the third sliding part 151 to approach or move away from the parts to be assembled.

[0063] By disposing the movable cylinder 150 , the relative distance between the limiting assembly 110 and the pushing assembly 120 and the part to be assembled can be adjusted, thereby further improving the accuracy of the assembly position of the U-shaped buckle 200 and the part to be assembled.

[0064] The working principle of the U-shaped buckle precision assembly mechanism 100 provided in this application is as follows:

[0065] First, the U-shaped buckle 200 is clamped on the limiting portion 1111 of the limiting plate 111, and the limiting plate 111 is driven to move along the second plane b by the lifting cylinder 112, so as to adjust the position of the limiting plate 111 to the edge of the side of the follower plate 121 facing the part to be assembled, so that the opening of the U-shaped buckle 200 is aligned with the part to be assembled;

[0066] The two-stage assembly cylinder 122 drives the follower plate 121 to move along the first plane a toward the direction close to the part to be assembled, until the follower plate 121 abuts against the side of the U-shaped buckle 200 away from the part to be assembled through the push rod 1213; at this time, the lifting cylinder 112 drives the limit plate 111 to move along the second plane b away from the part to be assembled to release the limit on the U-shaped buckle 200, and at the same time, the follower plate 121 continues to move toward the direction close to the part to be assembled until the push rod 1213 pushes the U-shaped buckle 200 to complete the assembly with the part to be assembled.

[0067] The above description is only an optional embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0068] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
