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 spring pin assembly device for the pull rod assembly of a trolley case. 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 assembly of tie rod assemblies is mainly done manually. For example, when installing the spring pin, the operator first holds the small tie rod and the spring pin with both hands, and then inserts the spring pin into the end of the small tie rod. This method is inefficient, and if the spring pin is tilted at a large angle when inserted, it will cause the spring pin to get stuck at the end of the small tie rod, requiring it to be pulled out and reinstalled, resulting in low efficiency.

[0004] To improve efficiency and achieve automated assembly on the production line, it is necessary to solve the problem of automatic assembly of spring pins and small tie rods. Utility Model Content

Detailed Implementation

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] like Figures 1 to 10 As shown, a spring pin assembly device for a suitcase handle assembly includes a pin feeding device 132, a pin positioning seat 133, a pin pressing device 136, and a pin transfer device 135, all mounted on a pin assembly frame 131. The pin feeding device 132, pin positioning seat 133, and pin pressing device 136 are arranged along the same axis. The pin feeding device 132 is used to sequentially feed out spring pins 503, ensuring that the spring pins 503 are oriented in the same direction. The pin positioning seat 133 is located at the discharge end of the pin feeding device 132 and is used to position the pins. The spring pin 503 is fed out by the feeding device 132; the pin pressing device 136 is located between the pin positioning seat 133 and the pull rod fixing device 10, and the pin pressing device 136 is arranged opposite to the small pull rod 501 on the pull rod fixing device 10; the pin transfer device 135 is located on one side of the pin positioning seat 133 and the pin pressing device 136; the pin transfer device 135 is used to move the spring pin 503 from the pin positioning seat 133 to the end of the small pull rod 501, and the pin pressing device 136 is used to press the spring pin 503 into the end of the small pull rod 501.

[0019] The pin feeding device 132 feeds the spring pins 503 sequentially to the pin positioning seat 133 in the same direction. The pin positioning seat 133 keeps the initial position of the spring pins 503 fixed, which facilitates the pin transfer device 135 to grab the spring pins 503. The pin transfer device 135 moves the spring pins 503 from the pin positioning seat 133 to the end of the small pull rod 501 and aligns the spring pins 503 with the small pull rod 501. The pin pressing device 136 is activated and presses the spring pins 503 into the end of the small pull rod 501, completing the automatic assembly of the spring pins 503.

[0020] Meanwhile, since the spring pin 503 can be set coaxially with the small tie rod 501 and is pressed in axially, the assembly of the spring pin 503 can be completed in one go, and it is not easy to get stuck, which greatly improves the assembly efficiency.

[0021] Specifically, the pin feeding device 132 includes a third vibratory feeder 1322 and a third feeding trough 1321. The third vibratory feeder 1322 is mounted on the pin assembly frame 131 and located at one end of the pin assembly frame 131. The third vibratory feeder 1322 is a disc vibratory feeder, a mature existing product, and will not be described in detail here. The third feeding trough 1321 is fixed on the third vibratory feeder 1322, and one end is movably located at the feed end of the pin positioning seat 133. The third vibratory feeder 1322 feeds the spring pins 503 sequentially through the third feeding trough 1321 in the same direction. The third feeding trough 1321 matches the spring pins 503, allowing the spring pins 503 to move along the axis onto the pin positioning seat 133.

[0022] To improve efficiency, both the pin feeding device 132 and the pin positioning seat 133 are equipped with two sets, enabling the installation of two small pull rods 501 and two spring pins 503 in one go. In other words, the assembly of the two small pull rods 501 and two spring pins 503 of the pull rod box is completed in one go, which facilitates the subsequent overall assembly of the pull rod assembly.

[0023] The pin positioning seat 133 is mounted on the pin positioning plate 1341, which is fixed to one end of the top of the pin assembly column 134. The pin assembly column 134 is fixed to the other end of the pin assembly frame 131. The pin positioning seat 133 is provided with a pin positioning groove 1331 and a pin clamping groove 1332. One end of the pin positioning groove 1331 is located at the end of the pin positioning seat 133, forming an open groove. The pin clamping groove 1332 is located on both sides of the pin positioning seat 133 and communicates with both sides of the pin positioning groove 1331, forming a cross-shaped groove.

[0024] The pin pressing device 136 includes a pin pressing cylinder 1362 and a pin pressing rod 1363. The pin pressing cylinder 1362 is horizontally arranged and fixed to the other end of the top of the pin assembly column 134, located between the pin positioning seat 133 and the pull rod fixing device 10. The pin pressing rod 1363 is mounted on the piston rod of the pin pressing cylinder 1362. When there are two pin pressing rods 1363, the pin pressing cylinder 1362 adopts a dual-axis cylinder to achieve the positioning of the pin pressing rods 1363. To prevent interference between the pin-pressing cylinder 1362 and the pin-transferring device 135 when moving the spring pin 503, the pin-pressing device 136 also includes a pin-pressing lifting cylinder 1361. The pin-pressing lifting cylinder 1361 is fixed to the other end of the top of the pin assembly column 134. The pin-pressing lifting cylinder 1361 is vertically mounted and is a dual-axis cylinder. The piston rod end of the pin-pressing lifting cylinder 1361 is connected to the pin-pressing cylinder 1362. When the pin-transferring device 135 moves the spring pin 503, the pin-pressing lifting cylinder 1361 is in a retracted state, placing the pin-pressing cylinder 1362 below the small pull rod 501, preventing interference with the spring pin 503 and improving operational reliability. The pin-pressing lifting cylinder 1361 is optional and can be included as needed.

[0025] To provide feedback on the pressed-in position of the spring pin 503 and ensure the reliability of the pressed-in, the pin pressing device 136 also includes a pin pressing sensor 1364. The pin pressing sensor 1364 is installed on the pin pressing cylinder 1362. The pin pressing sensor 1364 is used to detect the position of the piston rod of the pin pressing cylinder 1362, thereby detecting the pressed-in position of the spring pin 503. If the spring pin 503 is not fully pressed in, the pin pressing sensor 1364 will not detect the piston of the pin pressing cylinder 1362 and will issue an alarm.

[0026] The pin transplanting device 135 includes a pin transplanting linear module 1351, a pin transplanting seat 1352, a pin transplanting lifting cylinder 1353, a pin transplanting gripper cylinder 1354, and a pin transplanting clamping claw 1355. The pin transplanting linear module 1351 is mounted on the pin assembly frame 131 via a pin transplanting column 1357. The pin transplanting seat 1352 is mounted on the slide of the pin transplanting linear module 1351 and connected to the pin transplanting lifting cylinder 1353. The pin transplanting lifting cylinder 1353 is vertically arranged and is a dual-axis cylinder. The piston rod of the pin transplanting lifting cylinder 1353 is connected to the pin transplanting gripper cylinder 1354. The pin transplanting gripper cylinder 1354 is equipped with the pin transplanting clamping claw 1355, which is used to clamp the spring pin 503. The pin transplanting clamping claw 1355 has a groove that matches the spring pin 503. When two pin transplanting gripper cylinders 1354 are used, the pin transplanting gripper cylinders 1354 are connected to the piston rod of the pin transplanting lifting cylinder 1353 through the pin transplanting plate 1356.

[0027] The pin-transfer clamping claw 1355 clamps the spring pin 503 from the pin positioning seat 133 through the pin clamping groove 1332.

[0028] To improve the stability of the small pull rod 501 when the spring pin 503 is inserted into the end of the small pull rod 501 and to prevent the small pull rod 501 from deforming under force, an auxiliary fixing device 137 for the pull rod is also included. The auxiliary fixing device 137 for the pull rod is located between the pin pressing device 136 and the pull rod fixing device 10 and is used to fix the end of the small pull rod 501 when the spring pin 503 is pressed in. Specifically, the auxiliary fixing device 137 for the pull rod includes an auxiliary lifting cylinder 1371, an auxiliary gripper cylinder 1373 and an auxiliary clamping claw 1374. The auxiliary lifting cylinder 1371 can be fixed on the pin assembly frame 131 or on the conveyor line. The auxiliary lifting cylinder 1371 is a dual-axis cylinder and is vertically arranged. The auxiliary gripper cylinder 1373 is fixed on the piston rod of the auxiliary lifting cylinder 1371. The auxiliary clamping claw 1374 is symmetrically installed on the auxiliary gripper cylinder 1373 and is used to clamp the end of the small pull rod 501. The auxiliary clamping claw 1374 has a groove that matches the small pull rod 501. When preparing to press in the spring pin 503, the auxiliary lifting cylinder 1371 drives the auxiliary clamping claw cylinder 1373 to rise to the set position. Then, the auxiliary clamping claw cylinder 1373 drives the auxiliary clamping claw 1374 to clamp the two sides of the small pull rod 501, so that the small pull rod 501 is pressed into the end of the spring pin 503 and fixed. When two auxiliary clamping claw cylinders 1373 are used, the auxiliary clamping claw cylinders 1373 are connected to the piston rod of the auxiliary lifting cylinder 1371 through an auxiliary plate. After the pull rod auxiliary fixing device 137 clamps the end of the small pull rod 501, the pin pressing device 136 is activated again and presses the spring pin 503 into the end of the small pull rod 501.

[0029] A tie rod fixing device 10 is installed on the conveyor line to fix the small tie rod 501 and drive the small tie rod 501 to move between various workstations, realizing the automatic circulation of the small tie rod 501. 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 small tie rod 501.
