In existing automated fixture conveying devices, fixture linkage makes it impossible to convey a single fixture individually, and it is not convenient to return and reuse fixtures.
The system employs a support base, a movable base, a carrier, and a translational drive mechanism. The movable base moves independently by meshing with the synchronous belt through a toothed engagement between the synchronous belt and the movable base. The synchronous belt is driven by a drive motor to rotate the synchronous pulley. The system also features a positioning mechanism and elastic supports to ensure smooth engagement and cushioning of the movable base.
This allows for independent movement of each movable seat, facilitating collection and recycling, avoiding mutual interference, and improving the conveying efficiency and flexibility of the fixture.

[0024] The following detailed embodiments will be further explained in conjunction with the above-mentioned accompanying drawings.
[0025] Several specific details are set forth below to provide a thorough understanding of the concepts underlying the described embodiments. However, it will be apparent to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other instances, well-known processing steps are not specifically described.
[0026] In one embodiment of the assembly line fixture conveying device of this utility model, please refer to... Figure 1 , Figure 2 and Figure 6 ;in Figure 1 This is a structural diagram of a production line fixture conveying device, with the tooth profile of the synchronous belt omitted. A production line fixture conveying device includes a support base 100, a movable base 200, a carrier 300, and a translation drive mechanism 400. The support base 100 is provided with a linear guide rail 110; the movable base 200 slides on the linear guide rail 110, and a connecting member 210 is provided on the bottom side of the movable base 200. The bottom of the connecting member 210 has multiple meshing teeth 211; the movable base 200 is provided with a positioning part, and the carrier 300 is positioned on the positioning part. The carrier 300 is used to position workpieces to be processed or assembled.
[0027] Reference Figure 1 and Figure 2 The translation drive mechanism 400 includes a synchronous belt 410, a synchronous pulley 420, a drive motor 430, a support pulley 440, and a tensioning pulley 450. The two support pulleys 440 are located on the same side at both ends of the support base 100, the synchronous pulley 420 is located on one side of the support base 100, and the two tensioning pulleys 450 are respectively located on both sides of the synchronous pulley 420. The synchronous belt 410 is wound around the two support pulleys 440 and the two tensioning pulleys 450, supporting the inner ring of the synchronous belt 410 and tensioning it. The two tensioning pulleys 450 form a steering structure, causing a portion of the outer ring of the synchronous belt 410 to wrap around the synchronous pulley 420. The teeth of the synchronous belt 410 are located on the outer ring and mesh with the synchronous pulley 420 and the meshing teeth 211. The drive motor 430 is connected to the synchronous pulley 420 and is used to drive the synchronous pulley 420 to rotate. When the drive motor 430 drives the synchronous pulley 420 to rotate, the synchronous pulley 420 will drive the synchronous belt 410 to rotate, which in turn drives the connecting member 210 that meshes with the synchronous belt 410 and the movable seat 200 connected to the connecting member 210 to move together.
[0028] Specifically, the movable seat 200 can be slidably mounted on the linear guide rail 110 of the support base 100, and the carrier 300 for positioning the product can be positioned on the movable seat 200. Through the meshing teeth of the connecting member 210 at the bottom of the movable seat 200 engaging with the teeth of the synchronous belt 410, the drive motor 430 drives the synchronous pulley 420 to rotate, which in turn drives the synchronous belt 410, which in turn drives the movable seat to translate along the linear guide rail 110. When multiple movable seats 200 are mounted on the linear guide rail 110, the connecting seat 210 at the bottom of each group of movable seats 200 engages with the teeth of the synchronous belt 410, thus allowing each movable seat 200 to move via the synchronous belt 410. Since two movable seats 200 are independent of each other and do not interfere with each other, this facilitates the collection, return, and recycling of the movable seats.
[0029] Preferred, refer to Figure 1 and Figure 5 The system also includes a positioning mechanism 500, which comprises a lifting drive 510 and a positioning block 520. The lifting drive 510 is located on one side of the support base 100, and the positioning block 520 is located on the lifting drive 510. The positioning block 520 has a V-shaped groove 521. A positioning wheel 550 is located on one side of the movable seat 200 for positioning in the V-shaped groove 521. Specifically, when the movable seat 200 is transported to the position of the positioning mechanism 500, the lifting drive 510 drives the positioning block 520 to rise, and the positioning wheel 550 is positioned by the V-shaped groove 521, thereby achieving the positioning of the workpiece on the movable seat 200 and the positioning base 200.
[0030] Preferred, refer to Figure 3 and Figure 4 An elastic support 220 is provided between the connector 210 and the movable seat 200. The elastic support 220 elastically supports the connector 210 vertically, allowing the connector 210 to move up and down. At the moment the connector 210 engages with the synchronous belt 410, the connector 210 is displaced upwards, ensuring smooth engagement with the synchronous belt 410. Furthermore, when the movable seat 200 is prevented from continuing to transport during movement, the driving force of the synchronous belt 410 causes the connector 210 to overcome the elastic force of the elastic support 220 and displace upwards, resulting in slippage and preventing excessive stress on the synchronous belt 410.
[0031] Specifically, refer to Figure 3 and Figure 4The elastic support 220 includes a fixed base 221, a lifting base 222, and a compression spring 223. The fixed base 221 is located on the bottom side of the movable base 200, and a guide 224 is provided on one side of the fixed base 221. The lifting base 222 is slidably connected to the guide 224, and the compression spring 223 abuts against the fixed base 221 and the lifting base 222.
[0032] Preferred, refer to Figure 3 The top side of the lifting seat 222 is provided with a clearance notch 225, and a limiting hole is provided in the clearance notch 225. A limiting part 226 extends from one side of the fixed seat 221, and the limiting part 226 extends to the notch 225. The compression spring 223 is provided in the limiting hole, and the upper end of the compression spring 223 abuts against the limiting part 226.
[0033] Preferred, refer to Figure 1 and Figure 3 The bottom of the movable seat 200 is provided with a buffer 230 at one end and a blocking member 240 at the other end. The blocking member 240 is used to limit the buffer 230 of the next movable seat 200. This prevents adjacent movable seats 200 from colliding with each other, or can play a buffering role during the collision.
[0034] Preferred, refer to Figure 4 The buffer component 230 includes a connecting seat 231, a limiting rod 232, and a buffer spring 233. The connecting seat 231 is located on the bottom side of the movable seat 200 and has a guide hole. The limiting rod 232 is slidably connected to the guide hole. The buffer spring 233 is sleeved on the limiting rod 232 and abuts against one end of the connecting seat 231 and the limiting rod 232.
[0035] Preferred, refer to Figure 1 and Figure 4 The linear guide rail 110 has limiting grooves 111 on both sides, and the bottom of the movable seat 200 is also provided with a pulley 250, which is limited within the limiting grooves 111. This achieves the limitation of the movable seat 200.
[0036] 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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
