Description

Technical Field

[0001] This utility model relates to an automatic assembly device for the pull rod assembly of a trolley case, and more particularly to a pull rod sleeve device. Background Technology

[0002] Suitcase handle assemblies typically come in two specifications: two-section and three-section. Two-section handles have one fewer section than three-section handles. Three-section handles are suitable for small suitcases, ensuring sufficient handle length, while two-section handles are suitable for large suitcases. A two-section handle assembly includes a small handle and a large handle that are sequentially connected, a buckle at the end of the small handle, a spring pin and an inner tube sleeve, a gantry frame mounted on the small handle, a handle at the top of the small handle, and a movable top rod located inside the small handle. The large handle is fixed to the suitcase body.

[0003] The existing tie rod assembly is mainly done manually. For example, when connecting two tie rods, the operator takes out the small tie rod and the middle tie rod from two material boxes respectively. The small tie rod is already equipped with a buckle and spring pin, and the middle tie rod is already equipped with a middle sliding sleeve. Then, the small tie rod is inserted into the middle tie rod. When inserting the small tie rod, it needs to be inserted from the end without the middle sliding sleeve, and the spring pin must be matched with the side of the middle tie rod. After the small tie rod touches the middle sliding sleeve, the position of the small tie rod needs to be adjusted so that the small tie rod can be inserted into the middle sliding sleeve. Since the end of the small tie rod cannot be seen, it is time-consuming, laborious and inefficient to insert the small tie rod into the middle sliding sleeve. Another installation method involves first inserting the small pull rod into the middle pull rod, and then finally installing the middle sliding sleeve. To install the middle sliding sleeve, first insert it onto the small pull rod, then push it to the end of the middle pull rod, aligning it with the pull rod. Finally, insert the middle rubber sleeve into the middle pull rod, positioning it between the middle and small pull rods to reduce friction and improve service life. While this method makes assembly easier, it requires the operator to retrieve materials three times, necessitating three material frames. The overall efficiency improvement is limited, and the assembly process remains time-consuming and labor-intensive. Utility Model Content

Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figures 1 to 9 As shown, a tie rod sleeve device includes a staggered displacement device 142, a staggered pushing device 141, a second tie rod feeding device 15, a second sliding sleeve assembly device 16, and a sleeve insertion device 17. The staggered displacement device 142 is located on one side of the conveyor line, and a tie rod fixing device 10 is provided on the conveyor line. The tie rod fixing device 10 clamps the small tie rod 504 with a gripper. The conveyor line is used to drive the tie rod to move between different workstations. The staggered displacement device 142 is arranged parallel to the conveyor line. The staggered pushing device 141 is located on one side of the staggered displacement device 142 and is used to clamp the small tie rod 504. The small pull rod 504 on the pull rod fixing device 10 is pushed onto the staggered displacement device 142; the second pull rod feeding device 15 is located on the other side of the conveyor line and is used to move the middle pull rod 506 onto the empty pull rod fixing device 10; the second sliding sleeve assembly device 16 is located on one side of the conveyor line and is used to insert the middle sliding sleeve 505 into the end of the middle pull rod 506; the sleeve insertion device 17 is located at one end of the staggered displacement device 142 and above the conveyor line, and is used to insert the small pull rod 504 on the staggered pushing device 141 into the middle pull rod 506 and the middle sliding sleeve 505.

[0017] First, the small pull rod 504 with spring pin 503 is pushed from the pull rod fixing device 10 to the staggered displacement device 142 by the staggered pusher device 141. Then, the small pull rod 504 is moved to the insertion station by the staggered displacement device 142. The pull rod fixing device 10 moves from the staggered pusher device 141 to the second pull rod feeding device 15 along with the conveyor line. The second pull rod feeding device 15 places the middle pull rod 506 on the pull rod fixing device 10. Then, the pull rod fixing device 10 moves the middle pull rod 506 to the second sliding sleeve assembly device 16. The second sliding sleeve assembly device 16 inserts the middle sliding sleeve 505 into the end of the middle pull rod 506. Then, the conveyor line moves the middle pull rod 506 to the insertion station through the pull rod fixing device 10. Then, the insertion device 17 inserts the small pull rod 504 into the inside of the middle pull rod 506 and moves it onto the middle sliding sleeve 505 to complete the assembly.

[0018] The second sliding sleeve assembly device 16 includes a second vibratory feeder 161, a second linear module 163, a second lifting cylinder 164, a second pneumatic gripper 165, a second loading seat 162, a second upper pushing cylinder 168, a second lower pushing cylinder 166, a second upper pushing rod 169, and a second lower pushing rod 167. The second vibratory feeder 161 is located on one side of the second linear module 163, and its outlet is opposite to the second loading seat 162, used to sequentially transport the middle sliding sleeve 505 to... The second set of loading seat 162 is placed in the second set of fixing groove 1621 to position the middle sliding sleeve 505 for accurate gripping. The slide of the second set of linear module 163 is connected to the second set of lifting cylinder 164, and the second set of lifting cylinder 164 is connected to the second set of pneumatic gripper 165. The second set of pneumatic gripper 165 is used to grip the middle sliding sleeve 505. The second set of linear module 163 drives the second set of pneumatic gripper 165 to move to the end of the middle pull rod 506 located on the pull rod fixing device 10, so that the middle sliding sleeve 505 is aligned with the end of the middle pull rod 506. The second set of lower pusher cylinders 166 is located on one side of the conveyor line. The second set of lower pusher cylinders 166 is a dual-shaft cylinder and is connected to the second set of lower pusher rods 167. The second set of lower pusher rods 167 are coaxially aligned with the central pull rod 506. The second set of lower pusher cylinders 166 first inserts the second set of lower pusher rods 167 onto the central sliding sleeve 505, and then inserts it into the end of the central pull rod 506. The second set of upper pusher cylinders 168 is mounted on the piston rod of the second set of lower pusher cylinders 166 and is connected to the second set of upper pusher rods 169. The second set of upper pusher rods 169 movably abuts against the second set of lower pusher rods 167 and against the end of the central sliding sleeve 505, fully inserting the central sliding sleeve 505 into the end of the central pull rod 506.

The staggered placement platform 1422 is provided with a plurality of staggered placement grooves 1423. The staggered placement grooves 1423 are used to place small pull rods 504. The ends of the staggered placement grooves 1423 are symmetrically provided with first insertion inclined surfaces 1424. The first insertion inclined surfaces 1424 facilitate the insertion of small pull rods 504 and enable the spring pins 503 to retract, thereby improving positioning accuracy. Furthermore, in order to precisely adjust the height of the small pull rod 504 so that it can be accurately inserted into the middle pull rod 506, the staggered displacement device 142 also includes a staggered lifting seat 1425 and a staggered lifting linear module 1426. The staggered lifting seat 1425 is installed on the slide of the staggered displacement linear module 1421; the staggered lifting linear module 1426 is fixed on the staggered lifting seat 1425. The staggered lifting linear module 1426 is vertically arranged, and the slide of the staggered lifting linear module 1426 is connected to the staggered displacement platform 1422 through the staggered connecting seat 1427.

[0021] The second pull rod feeding device 15 includes a second pull rod feeding device 154, a second pull rod robotic arm 151, a second pull rod clamping device 152, and a second pull rod pushing device 155. The second pull rod feeding device 154 and the second pull rod pushing device 155 are located on one side of the conveyor line. The second pull rod robotic arm 151 is located on the other side of the conveyor line and is arranged opposite to the second pull rod feeding device 154. The second pull rod clamping device 152 is fixed on the second pull rod robotic arm 151. The second pull rod clamping device 152 includes a second pneumatic gripper 1521, which is used to clamp and release the pull rod. The second pull rod robotic arm 151 moves the middle pull rod 506 on the second pull rod feeding device 154 to the second pull rod pushing device 155 through the second pull rod clamping device 152. To improve clamping accuracy, the second pull rod clamping device 152 also includes a second clamping frame 1522 and a second clamping camera 1523. The second pneumatic gripper 1521 and the second clamping camera 1523 are both mounted on the second clamping frame 1522, which is mounted on the second pull rod robotic arm 151. The second pull rod pushing device 155 includes a second pull rod pushing linear module 1551, a second pull rod pushing rod 1552, and a second pull rod pushing seat 1553. The second pull rod pushing linear module 1551 is located on one side of the second pull rod feeding device 154 and also on one side of the conveyor line. The second pull rod pushing rod 1552 is mounted on the slide of the second pull rod pushing linear module 1551 and is opposite to the second pull rod pushing groove 1554 on the second pull rod pushing seat 1553. The second pull rod robotic arm 151 moves the middle pull rod 506 onto the second pull rod pushing groove 1554 via the second pull rod clamping device 152. The second pull rod pushing linear module 1551 pushes the middle pull rod 506 in the second pull rod pushing groove 1554 onto the pull rod fixing device 10 via the second pull rod pushing rod 1552, thereby achieving precise feeding of the middle pull rod 506 and ensuring that the end positions of the two middle pull rods 506 are fixed, which is convenient for subsequent assembly.

[0022] The second lever feeding device 154 is an existing mature feeding device, including a lifting device, a translation device, a pallet, etc., which will not be described in detail here.

[0023] The insertion device 17 includes a first insertion straight module 171, a first insertion guide post 172, a second insertion straight module 173, and a second insertion guide post 174. The first insertion straight module 171 is located at one end of the staggered displacement device 142 and above the conveyor line. The first insertion guide post 172 is installed on the slide of the first insertion straight module 171 and is also opposite to the middle sliding sleeve 505 on the tie rod fixing device 10. The second insertion straight module 173 is opposite to the first insertion straight module 171. The second insertion guide post 174 is installed on the slide of the second insertion straight module 173 and is also opposite to the small tie rod 504 on the staggered displacement device 142. The first set of linear insertion modules 171 drives the first set of insertion guide pins 172 to be inserted into the middle sliding sleeve 505 at the end of the middle pull rod 506, and the insertion depth of the first set of insertion guide pins 172 is greater than the length of the middle sliding sleeve 505, so that the first set of insertion guide pins 172 are inserted into the interior of the middle pull rod 506. The second set of linear insertion modules 173 drives the second set of insertion guide pins 174 to abut against the spring pin 503 at the end of the small pull rod 504, and pushes the small pull rod 504 toward the pull rod fixing device. The middle tie rod 506 on the 10 moves, causing the small tie rod 504 to insert into the middle tie rod 506. Then, the end of the small tie rod 504 inserts into the first set of insertion guide posts 172. The first set of insertion guide posts 172 makes the small tie rod 504 and the middle sliding sleeve 505 coaxially aligned, thus allowing the small tie rod 504 to smoothly insert into the middle sliding sleeve 505. The middle sliding sleeve 505 is located between the small tie rod 504 and the middle tie rod 506, completing the connection between the small tie rod 504 and the middle tie rod 506. A first set of insertion lifting cylinder 176 can also be installed between the first set of insertion guide posts 172 and the first set of insertion linear module 171, and a second set of insertion lifting cylinder 175 can be installed between the second set of insertion linear module 173 and the second set of insertion guide posts 174. The lifting cylinders are used to avoid interference during reciprocating movement. To prevent the small pull rod 504 from moving when it is inserted into the middle pull rod 506, and to improve the stability of the middle pull rod 506's positioning, a first positioning boss 1721 is provided on the first set of insertion guide posts 172. The first positioning boss 1721 abuts against the end of the middle sliding sleeve 505, ensuring that the middle pull rod 506 will not move when it is sleeved with the small pull rod 504. A first guide cone 1722 is provided on the first set of insertion guide posts 172. The first guide cone 1722 ensures that the small pull rod 504 can be accurately inserted into the first set of insertion guide posts 172, preventing the small pull rod 504 from abutting against the end of the first set of insertion guide posts 172 due to misalignment, thus improving the reliability and stability of the assembly.

[0024] like Figure 9As shown, the tie rod fixing device 10 is installed on the conveyor line to fix the middle tie rod 506 and drive the middle tie rod 506 to move between various workstations, realizing the automatic circulation of the middle tie rod 506. The tie rod fixing device 10 includes a tie rod fixing base plate 101, a tie rod finger cylinder 102, and a tie rod gripper 103. The tie rod finger cylinder 102 is fixed on the tie rod fixing base plate 101, and the tie rod gripper 103 is fixed on the tie rod finger cylinder 102 and is provided with a groove that matches the middle tie rod 504.
