Description

Technical Field

[0001] The utility model relates to the technical field of transport equipment, in particular to a transport mechanism. Background Art

[0002] Injection molding is an industrial process widely used in the manufacture of plastic products. It utilizes an injection molding machine to inject molten plastic material into a mold. After cooling and solidification, the resulting plastic product is of the desired shape and size. Injection molding is an efficient, precise, and controllable plastic product manufacturing process, widely used across multiple industries. By controlling the injection molding machine's parameters such as temperature, pressure, injection speed, and cooling time, along with appropriate mold design and fabrication, the filling, cooling, and solidification processes of the plastic material can be optimized to produce the desired plastic product.

[0003] After injection molding, small precision injection molded parts need to be placed on a tray. When the tray is full, they need to be transported and transferred.

This method not only requires high labor costs and increases the labor intensity of the staff, but also the manual transportation process is prone to shaking, resulting in an unstable transportation process, which can easily cause small precision injection molded parts to fall, especially in the medical device industry, which will cause contamination to the products. Therefore, we need to propose a transportation mechanism. Utility Model Content

[0028] The moving mechanism includes linear guide rails 25 and a slide 14 provided on two sets of top plates 3, and the slide 14 is mounted on the linear guide rails 25;

[0029] The clamping mechanism includes a connecting plate 15 and a lifting plate 17. The lifting plate 17 is located directly below the connecting plate 15. Side plates 16 are provided at the bottom of both ends of the connecting plate 15. The lower ends of the side plates 16 are fixedly connected to the tops of the two groups of slides 14 respectively. The lifting plate 17 is driven to rise and fall by a cylinder 18 installed on the connecting plate 15. Four groups of pneumatic fingers 19 for clamping the material tray are symmetrically installed on the lifting plate 17.

[0030] In actual use, the position of the clamping mechanism is moved by the moving mechanism. When it moves to the top of the pallet, it stops. The cylinder 18 drives the lifting plate 17 to descend until the pneumatic fingers 19 are located at the four corners of the pallet. The pneumatic fingers 19 clamp the four corners of the pallet for automatic grabbing. The cylinder 18 drives the lifting plate 17 to lift the pallet. The moving mechanism drives the clamping mechanism to move to the handling location again. The cylinder 18 drives the lifting plate 17 to descend and then activates the fingers to release the pallet to complete the handling of the material pallet.

[0031] In general, the device has a simple structure and is easy to use. It can realize the automatic grasping, transportation, positioning and release of material trays during medical device processing, improve the automation level of the production line, reduce labor intensity, and ensure stability and safety during the transportation process.

[0032] Also, see Figure 1-2 :

[0033] The vehicle also includes a drive mechanism for driving the slide 14 in the moving mechanism. The drive mechanism includes a motor 7. A right baffle 6 is mounted on one side of the top plate 3 at the upper end of the right support 2. The motor 7 is mounted on an outer wall of the right baffle 6. The output end of the motor 7 extends through the right baffle 6 and is fixedly connected to a drive wheel 8. First and second protrusions 11 and 12 are mounted on the top ends of the two sets of top plates 3, respectively. First and second synchronous wheels 23 and 24 are mounted on the first and second protrusions 11 and 12, respectively. A third synchronous belt 13 is interposed between the first and second synchronous wheels 23 and 24. A left baffle 5 is mounted above the first protrusion 11 at one end of the top plate 3 at the upper end of the left support 1. A shaft 10 is rotatably mounted on the left baffle 5. Two sets of driven wheels 9 are symmetrically mounted on the shaft 10. The drive wheels 8 are connected to the driven wheels 9 at one end of the shaft 10 via a first synchronous belt. The first synchronous wheel 23 includes an inner wheel and an outer wheel.

The two sets of clamps are fixed to the two sets of third synchronous belts 13 by fixing screws.

[0034] In actual use, the motor 7 is started so that the driving wheel 8 can drive the driven wheel 9 to rotate through the first synchronous belt, and the driven wheel 9 drives the inner wheel of the first synchronous wheel 23 to rotate through the second synchronous belt, and the outer wheel of the first synchronous wheel 23 drives the second synchronous wheel 24 to rotate through the third synchronous belt 13. During the movement of the third synchronous belt 13, the slide 14 can be driven to slide on the linear guide rail 25 through the clamping block. At the same time, the connecting plate 15 on the slide 14 is driven to move through the side plate 16 to achieve the adjustment of the position of the clamping mechanism; the forward and reverse rotation of the motor 7 can change the rotation direction of the third synchronous belt 13, thereby adjusting the moving direction of the clamping mechanism.

[0036] Two sets of linear bearings are symmetrically arranged on both sides of the cylinder 18 on the connecting plate 15. Guide rods 20 are slidably fitted within the linear bearings. The lower ends of the guide rods 20 are fixedly connected to the top surface of the lifting plate 17. A limit plate 21 is provided between the upper ends of the two sets of guide rods 20 on the same side of the connecting plate 15. A buffer 22 is installed at the bottom of the limit plate 21.

[0037] The cooperation between the linear bearing and the guide rod 20 can play a good guiding role in the lifting process of the lifting plate 17, and at the same time improve the stability of the lifting plate 17 during the lifting process, so that the material tray also has high stability during the handling process;

[0038] At the same time, by arranging a limit plate 21 with a buffer 22 at the upper end of the guide rod 20, it can not only play a limiting role, but also in the process of unloading, the buffer 22 can play a good buffering role between the limit plate 21 and the connecting plate 15, avoiding the limit plate 21 directly hitting the connecting plate 15 and causing the material tray to shake violently or even detach, further improving the safety and stability of the device.
