Description

[0002] Robots have been widely used in automated welding production and manufacturing, and robot automation is applied to parts products with complex and diverse processes. Due to problems such as the size and layout of the workshop, the entire production line may be composed of multiple strings connected in series, as well as the problem of the inherent failure rate of the equipment itself. Therefore, large-distance conveying and part buffering are required between some workstations. In this way, even if the equipment at the previous workstation fails, it can ensure that the subsequent workstations can produce normally for a certain period of time, and it can also ensure that the subsequent workstations can produce normally without delaying the maintenance.

[0003] The existing conveying chain for degree conveying uses parts placed on a fixed fixture for positioning, and the conveying chain carries the fixture to the designated position together. Due to the reason of the positioning fixture and the length problem of the conveying chain, the motor chain is subjected to large force. Therefore, the existing conveying chain is not suitable for being too long, and a high-power motor is required for the motor, resulting in high costs. For this reason, an automatic conveying chain with a buffering and positioning function is designed. Summary of the Invention

[0031] Hereinafter, with reference to the drawings, the preferred embodiments of the present utility model will be described in detail to further elaborate on the present utility model.

[0032] First, in combination with Figures 1 - 3 Describe an automatic conveying chain with a buffer and positioning function according to an embodiment of the present utility model, which is used for the buffer conveying of parts (taking the battery tray 9 as an example in the embodiments of this application), and its application scenarios are very wide.

[0033] As Figures 1 - 3 shown, an automatic conveying chain with a buffer and positioning function according to an embodiment of the present utility model includes a roller conveying line, a plurality of first detectors 2, a plurality of second detectors 3, a plurality of blocking modules 4, two in - place detectors 5, and a lifting module.

[0034] Specifically, as Figures 1 - 3 shown, the roller conveying line is composed of a plurality of buffer sections 11 and a loading section 12. After the plurality of buffer sections 11 are connected in sequence, they are connected to the loading section 12. The buffer sections 11 are used to realize the buffer of the battery tray 9 and convey it one by one to the loading section 12 for loading and processing. A V - shaped guide plate is also provided at the connection between the last buffer section 11 and the loading section 12 to keep the battery tray 9 in the same conveying position when entering the loading section 12.

[0035] Specifically, as Figures 1 - 3 shown, a plurality of first detectors 2 are respectively arranged on one side of the plurality of buffer sections 11 to respectively detect whether there are parts on their corresponding buffer sections 11.

[0036] Specifically, as Figures 1 - 3 shown, a plurality of second detectors 3 are respectively arranged on one side of the ends of the plurality of buffer sections 11 to detect whether the parts on the previous buffer section 11 are completely conveyed to the next buffer section 11 or the loading section 12, preventing the problem of collision caused by placing the battery tray 9 at the discharging place before the parts have completely entered the next buffer section 11.

[0037] Specifically, as Figures 1 - 3 shown, a plurality of blocking modules 4 are respectively arranged at the tail ends of a plurality of buffer segments 11 for blocking the parts conveyed on the buffer segments 11. Any one of the blocking modules 4 includes: a blocking cylinder 41 and a blocking member 42. The blocking cylinder 41 is arranged at the tail end of any one of the buffer segments 11; the blocking member 42 is arranged at the output end of the blocking cylinder 41 and moves up and down under the drive of the blocking cylinder 41 to block the parts conveyed on the corresponding buffer segment 11.

[0038] Specifically, as Figures 1 - 3 shown, two in-place detectors 5 are arranged at the tail end of the loading section 12 for detecting whether the parts conveyed to the loading section 12 are conveyed in place, so as to send an in-place signal to achieve lifting and positioning.

[0039] Specifically, as Figures 1 - 3 shown, the lifting module is arranged at the bottom of the loading section 12 for lifting the parts conveyed to the loading section 12. The lifting module includes: a lifting frame 61, a lifting cylinder 62, a lifting platform 63, a plurality of positioning members 64 and a guiding assembly. The lifting frame 61 is arranged at the bottom of the loading section 12; the lifting cylinder 62 is arranged on the lifting frame 61; the lifting platform 63 is arranged at the output end of the lifting cylinder 62; a plurality of positioning members 64 are arranged at the top of the lifting platform 63; the guiding assembly connects the lifting frame 61 and the lifting platform 63 and is used for guiding the lifting movement of the lifting platform 63.

[0040] Furthermore, as Figure 3 shown, the guiding assembly includes: four guiding sleeves 651 and four guiding rods 652. The four guiding sleeves 651 are arranged at the four corners of the lifting frame 61; the top ends of the four guiding rods 652 are respectively connected to the four corners of the bottom of the lifting platform 63, and the bottom ends of the four guiding rods 652 respectively penetrate through the four guiding sleeves 651.

[0041] Furthermore, as Figure 1 shown, an automatic conveying chain with a buffer and positioning function according to an embodiment of the present invention further includes: two brackets 71. The two brackets 71 respectively fix the two in-place detectors 5 on both sides of the tail end of the loading section 12, and blocking blocks 72 are respectively arranged on the two brackets 71 for blocking the parts conveyed in place.

[0042] Furthermore, as Figure 1 shown, an automatic conveying chain with a buffer and positioning function according to an embodiment of the present invention further includes: a feeding detector 81. The feeding detector 81 is arranged on one side of the head end of the loading section 12.

[0043] Furthermore, as Figure 1 shown, guiding wheels 82 are arranged on both sides of the roller conveyor line for guiding the conveying of the battery tray 9.

[0044] During use, when the first detector 2 and the second detector 3 on the first buffer section 11 detect a no-part state, parts can be placed on the first buffer section 11. When the first detector 2 and the second detector 3 on the second buffer section 11 detect a no-part state, the blocking module 4 on the first buffer section 11 opens and no longer blocks, enabling the parts to be conveyed to the second buffer section 11. Thus, according to this detection and conveying logic, continuous conveying of parts is achieved. When parts are conveyed into the loading section 12, the feeding detector 81 will detect them. And when the parts are completely conveyed to the loading section 12 and blocked by the blocking blocks 72 on the two brackets 71, after being detected by the two in-place detectors 5, it indicates that the parts on the loading section 12 are conveyed in place. Then, through the operation of the lifting cylinder 62, the lifting platform 63 and multiple positioning members 64 are driven to lift and position the parts, and then they are grabbed by an external robot and taken away.

[0045] As mentioned above, with reference to Figures 1 - 3 An automatic conveying chain with a buffering and positioning function according to an embodiment of the present invention is described above, having the following beneficial effects: The conveying chain of the present application is a low-cost, multi-section conveying type of conveying chain; compared with the existing conveying, multiple low-power motors can be selected for combined sectional conveying, and it can convey over a long distance. Also, it is not necessary to place the parts on a positioning fixture for positioning and conveying, only need to position the parts at the final grasping position, thus reducing the production cost.
