DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, understandable and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0020] As shown in Figure 1 The embodiment of the present application provides a buckle grabbing mechanism, which comprises a first lifting driving mechanism 1, a second lifting driving mechanism 2 and a clamping jaw assembly 3. The driving end of the first lifting driving mechanism 1 is connected with the second lifting driving mechanism 2. The clamping jaw assembly 3 comprises a hoop 31 and a clamping jaw 32. The hoop 31 is sleeved on the clamping jaw 32. One end of the clamping jaw 32 is connected with the second lifting driving mechanism 2 through a fixed plate 21. The driving end of the second lifting driving mechanism 2 is connected with the hoop 31. The second lifting driving mechanism 2 is used for driving the hoop 31 to move up and down to perform closing and loosening operations on the clamping jaw 32.

[0021] Specifically, the external driving mechanism drives the first lifting driving mechanism 1 to drive the second lifting driving mechanism 2 and the clamping jaw assembly 3 to move to the upper side of the buckle. The first lifting driving mechanism 1 drives the second lifting driving mechanism 2 to drive the clamping jaw assembly 3 to move downward to the buckle. The four profiled clamping heads 002 of the clamping jaw 32 are located at the outer side of the buckle. The second lifting driving mechanism 2 drives the hoop 31 to move downward along the fixed plate 21. The sleeve 311 of the hoop 31 tightens the four profiled clamping heads 002 of the clamping jaw 32, so that the four profiled clamping heads 002 clamp the buckle groove. The first lifting driving mechanism 1 drives the clamping jaw assembly 3 to drive the buckle to move upward. When the external driving mechanism drives the first lifting driving mechanism 1 to drive the buckle to move to the assembly station, the first lifting driving mechanism 1 drives the clamping jaw assembly 3 to move downward and be positioned on the assembly station. The second lifting driving mechanism 2 drives the hoop 31 to move upward along the fixed plate 21. The hoop 31 is separated from the four profiled clamping heads 002 of the clamping jaw 32. The four profiled clamping heads 002 are opened outward to loosen the buckle.

[0022] In the above structure, the second lifting driving mechanism 2 is arranged to drive the hoop 31 to move up and down, so that the closing and loosening operations on the clamping jaw 32 are realized. Therefore, the clamping and loosening operations of the clamping jaw 32 on the product are realized, and the clamping efficiency and clamping strength are improved. The first lifting driving mechanism 1, the second lifting driving mechanism 2, the hoop 31 and the clamping jaw 32 are arranged to cooperate with each other, so that the grabbing operation on the buckle is realized. The buckle grabbing mechanism not only has a compact structure and occupies a small space, but also has high grabbing efficiency, so that the time cost is greatly saved.

[0023] As shown in Figure 2 and Figure 4As shown in the drawings, in one embodiment, the clamping jaw 32 of the buckle grabbing mechanism comprises an internally hollow connecting column 321, four profiled clamping pieces 322 for clamping the buckle are arranged along the circumference of the connecting column 321, a clamping cavity for accommodating the buckle is arranged between the four profiled clamping pieces 322, the profiled clamping piece 322 comprises an arc-shaped clamping plate 001 arranged vertically and a profiled clamping head 002 arranged outwardly obliquely, a fixed block 22 is arranged on the second lifting driving mechanism 2, a through hole 221 is arranged on the fixed block 22 for the four profiled clamping pieces 322 and the hoop 31 to pass through, and the four profiled clamping heads 002 are located below the through hole 221. When the first lifting driving mechanism 1 drives the clamping jaw 32 to move towards the buckle, the buckle extends into the clamping cavity of the profiled clamping piece 322, and the four profiled clamping heads 002 are respectively located on the outer side of the circumference of the buckle. When the second lifting driving mechanism 2 drives the sleeve 311 of the hoop 31 to move downward, the hoop 31 tightens the four obliquely arranged profiled clamping heads 002, and the four profiled clamping heads 002 move inward to clamp the buckle. When the second lifting driving mechanism 2 drives the sleeve 311 of the hoop 31 to move upward, the sleeve 311 is separated from the four profiled clamping heads 002, and the profiled clamping heads 002 open outward to release the buckle. This arrangement facilitates clamping and releasing the buckle, improves the clamping strength, and prevents the buckle from falling off during movement.

[0024] As shown in the drawings, Figure 4 In one embodiment, the profiled clamping piece 322 of the buckle grabbing mechanism is made of elastic material. This arrangement improves the durability of the clamping jaw 32.

[0025] As shown in the drawings, Figure 2 and Figure 3 In one embodiment, the hoop 31 of the buckle grabbing mechanism comprises a through sleeve 311, a plurality of arc-shaped guide plates 312 are arranged along the circumference of the sleeve 311, an arc-shaped guide hole 211 is arranged on the fixed plate 21 for the arc-shaped guide plate 312 to pass through, and the arc-shaped guide plate 312 is connected with the driving end of the second lifting driving mechanism 2 through the arc-shaped guide hole 211 of the fixed plate 21. Four arc-shaped guide plates 312 are arranged at intervals along the circumference of the sleeve 311, the sleeve 311 is sleeved on the four arc-shaped clamping pieces, and the four arc-shaped guide plates 312 are connected with the driving end of the second lifting driving mechanism 2 through the four arc-shaped guide holes 211 of the fixed plate 21. The second lifting driving mechanism 2 drives the four arc-shaped guide plates 312 to move the sleeve 311 up and down along the four arc-shaped guide holes 211 of the fixed plate 21. The arrangement of the sleeve 311 facilitates the folding and releasing operation of the four profiled clamping heads 002. The arrangement of the arc-shaped guide plate 312 facilitates the guiding and stroke limiting of the sleeve 311.

[0026] As shown in the drawings, Figure 1As shown, in one embodiment, the first lifting drive mechanism 1 of the buckle gripping mechanism includes a mounting plate 11 and a first cylinder 12. The first cylinder 12 is mounted on the top of the mounting plate 11, and its drive end is connected to the second lifting drive mechanism 2. The first cylinder 12 drives the connecting plate 23 of the second lifting drive mechanism 2, which in turn drives the second cylinder 24 and the gripper assembly 3 to move up and down along the mounting plate 11 to grip and release the buckle. This arrangement facilitates the up and down movement of the gripper assembly 3 to grip the buckle, improving gripping efficiency.

[0027] like Figure 1 As shown, in one embodiment, the second lifting drive mechanism 2 of the latching gripping mechanism includes a connecting plate 23 and a second cylinder 24. The second cylinder 24 is mounted on the top of the connecting plate 23, and its drive end is connected to the hoop 31. The connecting plate 23 and the first lifting mechanism are slidably engaged via a sliding assembly 25. The second cylinder 24 drives the four arc-shaped guide plates 312 of the hoop 31 to move the sleeve 311 up and down. This arrangement improves the closing and opening efficiency of the hoop 31 on the gripper 32, thereby improving the clamping efficiency of the gripper 32.
