Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and in particular to a material feeding platform. Background Technology

[0002] A car airbag is a passive safety device designed to protect occupants in the event of a collision. It inflates rapidly to create a buffer between the occupant and hard objects inside the vehicle, reducing the impact damage. Airbags are typically used in conjunction with seat belts for optimal protection.

[0003] The airbag is the core component of an airbag. To meet the increasing market demand, manufacturers typically use sewing machines to sew airbags. However, because airbags have a large surface area when flattened, the sewing process is usually separated and handled manually, which reduces efficiency. If a robotic arm is used to transfer the main components of the airbag, the gripping area of ​​the robotic arm needs to be increased, resulting in an overly complex and costly structure. Furthermore, the airbag material is relatively soft, and robotic arms are prone to shifting during transport, requiring manual re-smoothing, which affects subsequent automatic sewing and reduces efficiency.

[0014] Furthermore, the first moving component includes a first connecting arm connected to the second synchronous belt, and the second moving component is provided with a second connecting arm connected to the second synchronous belt, with the connection points of the first connecting arm and the second connecting arm to the second synchronous belt being diagonally arranged.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0039] Main seat 1, with an auxiliary seat 11 separate from the main seat 1 on both sides, as shown in the figure. The auxiliary seats 11 on both sides form a certain distance from the main seat 1 to facilitate the movement of the first moving component 3 and the second moving component 4. The feeding frame 2 is provided with a receiving mold 21 for accommodating the main body of the car airbag. Connecting parts 22 are provided on the left and right wings of the feeding frame 2, such as... Figure 5 As shown, the connector 22 includes a first abutment portion 221 and a second abutment portion 222 arranged perpendicularly to each other. During assembly, the second abutment portion 222 is positioned away from the first abutment portion 221. To facilitate positioning after the feeding frame 2 moves, two positioning components 6 at different positions are provided on the main seat 1, such as... Figure 7 As shown, the positioning component 6 includes a positioning post 61, with a positioning lifting cylinder 62 connected to the lower end of the positioning post 61.

Two positioning components 23 are symmetrically distributed at the corners of the loading frame 2. Each positioning component 23 has a positioning through hole 231 that matches the positioning post 61, ensuring that the two loading frames 2 can align with the positioning through hole 231 and the positioning post 61 after each alternating movement, maintaining a level surface during loading and operation. Figure 2 As shown, multiple sets of supporting components 7 are also provided behind the main seat 1. The supporting components 7 include a supporting base 71 and a supporting member 72 rotatably mounted on the supporting base 71. The supporting member 72 is used to support the rear end of the feeding frame 2, so that when the feeding frame 2 moves to the rear for operation, the supporting member 72 can hold the feeding frame 2 in place. The setting of the supporting components 7 can reduce the volume of the main seat 1 and create a larger space at the rear, so that the rear side of the feeding frame 2 is suspended, which is convenient for operation with other equipment, such as sewing machines. Preferably, the supporting member 72 can adopt a roller structure and be set on the supporting base 71 through a movable shaft, so that the position can be adjusted and moved while supporting the feeding frame 2 without affecting the overall operation.

Figure 1 and Figure 2 As shown, in this embodiment, the two feeding frames 2 are a first feeding frame 24 and a second feeding frame 25, respectively.

Figure 8 and Figure 9As shown, a first abutting groove 311 matching the first abutting part 221 is provided at the end of the first lifting member 31. When it cooperates with the first lifting member 31, the first abutting part 221 will be completely inserted into the first abutting groove 311, which can play a certain limiting role. The first moving component 3 includes a first fixed base 32 and a first lifting cylinder 33 fixed to the first fixed base 32.

[0041] The aforementioned second moving component 4 is provided with a liftable second lifting member 41, which abuts against the connecting member 22 of the second feeding frame 25. Specifically, as shown... Figure 8 and Figure 9 As shown, a second recessed position 411 matching the second abutting part 222 is provided on the second lifting member 41. When the two work together, the second abutting part 222 will be inserted into the second recessed position 411. Similarly, the second recessed position 411 will play the role of support and limit. The second moving component 4 includes a second fixed base 42 and a second lifting cylinder 43 fixed to the second fixed base 42. The second lifting cylinder 43 is connected to the second lifting member 41.

[0042] In this embodiment, the synchronous drive component 5 is connected to the first moving component 3 and the second moving component 4 respectively, so that the first moving component 3 and the second moving component 4 move synchronously in opposite directions. Specifically, a first connecting plate 111 is connected to the upper end of the auxiliary base 11, and a first slide rail 112 and a first slider 113 movably disposed on the first slide rail 112 are provided on the first connecting plate 111. The first slider 113 is fixedly connected to the first fixed base 32. A second connecting plate 114 with the opposite direction to the first connecting plate 111 is connected to the lower end of the auxiliary base 11. A second slide rail 115 and a second slider 116 movably disposed on the second slide rail 115 are provided on the second connecting plate 114. The second slider 116 is fixedly connected to the second fixed base 42, and a first installation space 117 is formed between the first connecting plate 111 and the second connecting plate 114. Figure 3 , Figure 8 and Figure 9As shown, the aforementioned synchronous drive assembly 5 includes a synchronous drive motor 51 fixed to the bottom of the main seat 1, a first synchronous pulley set 52, and two sets of second synchronous pulley sets 53. The first synchronous pulley set 52 includes a synchronous transmission rod 521 and a first synchronous belt 522. A first synchronous pulley 523 is connected to the middle of the synchronous transmission rod 521. The first synchronous pulley 523 and the synchronous drive motor 51 are linked through the first synchronous belt 522. Each set of second synchronous pulley sets 53 includes two second synchronous pulleys 531 rotatably disposed in the first mounting space 117, and a second synchronous belt 532 disposed on the two second synchronous pulleys 531. The 532 is installed on the two second synchronous pulleys 531 to form a closed ring. The second synchronous pulleys 531 are connected to the end of the synchronous transmission rod 521 through a coupling. The first moving component 3 mentioned above includes a first connecting arm 321 connected to the second synchronous belt 532. In this embodiment, the first connecting arm 321 is located at the rear end of the first fixed seat 32. The second moving component 4 is provided with a second connecting arm 421 connected to the second synchronous belt 532. In this embodiment, the second connecting arm 421 extends from the rear side of the second fixed seat 42. The connection points of the first connecting arm 321 and the second connecting arm 421 with the second synchronous belt 532 are diagonally arranged.

[0043] To increase the stability of the feeding frame 2 when operating with other equipment, multiple evenly arranged auxiliary through holes 18 are provided in the middle of the main seat 1. A set of clamping components 8 is provided under each auxiliary through hole 18, such as... Figure 6 and Figure 7 As shown, the clamping assembly 8 includes a clamping lifting cylinder 81 fixed to the main seat 1 and a clamping seat 82 connected to the clamping lifting cylinder 81. The clamping lifting cylinder 81 is fixed to the clamping main seat 83. A clamping cylinder 84 and a clamping member 85 are fixed to the clamping seat 82 via a movable shaft. The lower end of the clamping member 85 is open, and a spherical bearing 86 connected to the clamping cylinder 84 is provided at the opening. The other end of the clamping member 85 away from the opening is folded back to form a clamping part 851.

[0044] The working principle of this utility model can be briefly described as follows: Figure 1As shown, in the initial position, the first feeding frame 24 is at the front end of the main seat 1, and the second feeding frame 25 is at the rear end of the main seat 1. At this time, the two positioning lifting cylinders 62 located below the main seat 1 are in the lifted state, that is, the positioning column 61 is raised and inserted into the positioning through hole 231 of the positioning component 23 of the first and second feeding frames. The clamping component 8 presses down on the front end of the second feeding frame 25, and the bearing component 72 presses down on the rear end of the second feeding frame 25. The left and right ends of the second feeding frame 25 are supported by the second lifting component 41. The first feeding frame 24 is placed on the front end. When starting the operation, the main material can be placed on the receiving mold 21 manually. After the feeding is completed, Two positioning and lifting cylinders 62 are activated, moving the positioning pin 61 downwards and disengaging it from the positioning through hole 231. Then, the clamping assembly 8 releases the second loading frame 25. The first lifting cylinder 33 and the second lifting cylinder 43 are activated simultaneously, raising the first loading frame 24 and the second loading frame 25 at the same time. The first loading frame is slightly higher than the upper end of the main seat 1, and the second loading frame is raised to a higher height than the first loading frame to avoid collisions during reverse movement. Then, the synchronous drive motor 51 is activated, sequentially driving the first synchronous pulley set 52 and the second synchronous pulley set 53, causing the second synchronous belt 532 to rotate. This, in turn, drives the first lifting assembly and the first loading frame 24 towards the main seat. The rear end of the first lifting component 1 and the second lifting component 25 move towards the front end of the main seat 1. When the preset stroke is reached, the synchronous drive motor 51 stops, and then the first lifting motor and the second lifting motor start simultaneously, lowering the first lifting frame 24 and the second lifting frame 25. The second lifting component 41 can move down to its lowest point, placing the second lifting frame 25 at the front end of the main seat 1, where the main seat 1 supports the second lifting frame 25. The first lifting frame 24 also descends with the first lifting component 31, with one end of the first lifting frame 24 placed on the main seat, and the other end of the first lifting frame 24 away from the positioning component 23 just abutting against the bearing component 72, so that the bearing... Part 72 can hold the edge of the first feeding frame 24, while the first lifting part 31 will maintain the supporting action of the first feeding frame 24. Then, the two positioning lifting cylinders 62 are activated at the same time, raising the positioning column 61 and inserting it into the positioning through hole 231 to complete the positioning. Then, the pressing lifting cylinder 81 is activated, and the pressing part 85 is placed above the first feeding frame 24 through the auxiliary through hole 18. Then, the pressing cylinder 84 is activated, and with the cooperation of the joint bearing 86, the pressing part 851 can press the other side of the first feeding frame 24. In this way, the first feeding frame 24 can be fixedly positioned. Then, it can be sewn with sewing machine or other equipment. After completion, the above actions can be repeated.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
