Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to a dual-mode rotary feeding device and welding system. Background Technology

[0002] In today's booming industrial manufacturing sector, welding, as a core technology for joining materials, has permeated many key industries, including automobile manufacturing, electronic equipment assembly, and plastic product molding. Hot plate welding machines, with their unique working mechanism and wide range of applications, occupy an indispensable position in the production processes of various products. However, most mainstream hot plate welding machines on the market today, including horizontal hot plate welding machines, adopt a single-station structure design. This traditional design has revealed a series of problems that seriously restrict the improvement of production efficiency and the smooth operation of the production line in actual production applications.

[0003] Single-station hot plate welding machines have significant limitations in the entire production process. Operators must strictly follow a predetermined sequence: first, the material to be welded is precisely placed on the worktable; then, the welding equipment's operating program is started; followed by a lengthy waiting period where the hot plate heats and pressurizes the material until the welding process is complete. Only after the welded material is successfully removed can the next material be installed on the worktable, thus initiating a new welding cycle. This sequential operation mode results in a considerable period of idle time after each welding operation. During this time, the equipment is completely idle, unable to achieve its intended production efficiency, and significantly wastes valuable production resources.

[0004] From a macro-operational perspective of the production line, this single-station design significantly hinders the continuity of the production line. Since each material's welding operation must be performed sequentially, if the welding of the previous material is not completely completed, the subsequent material cannot enter the welding stage in a timely manner. This makes the production line prone to intermittent stoppages. Taking a large-scale automotive parts manufacturing production line as an example, if a single-station hot plate welding machine is used, and the welding time in any welding stage is extended due to various factors, the rhythm of the entire production line will be completely disrupted. Subsequent critical processes such as parts assembly and quality inspection will be affected to varying degrees, leading to a sharp decline in production efficiency and a significant increase in production costs.

[0005] Although some companies have attempted to explore dual-station hot plate welding machine designs to improve production efficiency, this concept has encountered severe challenges in practical implementation. The material assembly process in conventional hot plate welding machines inevitably exposes the internal welding environment. During operation, the hot plate welding machine contains hazardous factors such as high temperature and high pressure. Prolonged exposure to this welding environment poses a significant risk to operator safety during material assembly, as they are highly susceptible to serious personal injury from contact with the high-temperature hot plates, high-pressure airflow, or other dangerous components. This undoubtedly presents a major safety hazard and is a key obstacle to the realization of dual-station hot plate welding machines.

[0006] In today's increasingly competitive market, industries are placing ever-rising demands on production efficiency and product quality. Against this backdrop, existing single-station hot plate welding machines, due to their inherent inefficiency and the practical limitations of dual-station operation, are no longer sufficient to meet the urgent needs of enterprises for efficient and safe production. Therefore, developing a new type of hot plate welding machine that can effectively overcome the drawbacks of single-station machines while ensuring safe production and successfully achieving efficient operation with dual or even multi-station configurations has become a crucial issue that urgently needs to be addressed in the current industrial production field.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0028] See Figure 1 As shown, this embodiment provides a dual-mode rotary feeding device, which includes: a connecting frame 100, which is disposed at the feed inlet of the processing space and can rotate around a rotation center line 1001. The connecting frame 100 has two connecting surfaces 110 and at least one positioning hole 140. The two connecting surfaces 110 are disposed on opposite sides of the connecting frame 100 in the thickness direction. The at least one positioning hole 140 is disposed on the edge of the connecting frame 100, recessed inward from the edge of the connecting frame 100 and avoiding the rotation center line 1001; Positioning mechanism 400 includes at least one locking driver 410 and at least one locking pin 420. The locking driver 410 is fixed to the edge of the processing space, and the locking pin 420 is disposed at the working end of the locking driver 410 and passes through / releases from the positioning hole 140 through the locking driver 410. Protective mechanism 300 is disposed around the connecting frame 100, is connected to the connecting frame 100 and rotates synchronously with the connecting frame 100 to block the feed port of the processing space.

[0029] The dual-mode rotary feeding device described in this embodiment provides two connecting surfaces 110 through a rotatable connecting frame 100 for dual-station feeding. Simultaneously, the connecting frame 100, in conjunction with the positioning mechanism 400, enables precise positioning during rotation. Furthermore, the stop function of the protective mechanism 300 ensures that the connecting frame 100 completely isolates the processing space during feeding, thereby significantly improving safety during the feeding process. Compared to conventional feeding equipment at present, this application offers advantages such as high feeding efficiency, safe and stable operation, high positioning accuracy, high controllability, and wide applicability.

[0030] The dual-mode rotary feeding device in this embodiment is applied to a hot plate welding system. It is used to move the hot plate structure to be welded into the welding processing space. The connecting frame 100 serves as both a material mounting and connecting structure and a rotary transport structure. The material to be processed can be assembled onto the connecting surface 110 using bolts or other connectors. Then, the rotation of the connecting frame 100 moves the material to be processed into the processing space. The positioning mechanism 400 controls the rotation angle of the connecting frame 100 to ensure its stability during material assembly or welding. The protective mechanism 300 blocks the loading port of the processing space to isolate it from the high-temperature welding environment, thereby ensuring the safety of the personnel handling the material.

[0031] See Figure 2 and Figure 3As shown, the connecting frame 100 in this embodiment includes two connecting surfaces 110. In actual processing, one connecting surface 110 faces the welding processing space, and the other connecting surface 110 faces the external processing space. Furthermore, the connecting surfaces 110 in this embodiment are provided with multiple weight-reducing holes 150 and connecting holes. In different embodiments, other types of connecting structures can also be provided on the connecting surfaces 110 to realize the assembly of the materials to be processed.

[0032] In this embodiment, the dual-mode rotary feeding device further includes a rotary drive mechanism 200, which includes a rotary driver 210, a drive shaft 220, and a housing 230. One end of the drive shaft 220 is connected to the rotary driver 210, and the other end passes through and is connected to the connecting frame 100. The rotation center line 1001 coincides with the central axis of the drive shaft 220, and the housing 230 is arranged around the drive shaft 220. Further, the rotary driver 210 is preferably a rotary motor, which is located at the center of the bottom surface of the connecting frame 100. The rotation center line 1001 extends along the height direction of the connecting frame 100 and is located at the center of the connecting frame 100. The drive shaft 220 is used to transmit the rotational driving force of the rotary driver 210 to the connecting frame 100, and the housing 230 is used to protect the drive shaft 220 to extend its service life.

[0033] In this embodiment, the positioning mechanism 400 is disposed on the top of the connecting frame 100, thereby the positioning hole 140 is recessed downward from the top surface of the connecting frame 100. Further, the connecting frame 100 also includes at least one first bushing 130, which is correspondingly disposed in at least one of the positioning holes 140 to facilitate cooperation with the locking pin 420. Specifically, the first bushing 130 can absorb the vibration and impact generated by the locking pin 420 during operation, thereby extending the service life of the positioning mechanism 400.

[0034] See Figure 3 and Figure 4 As shown, to achieve the connection between the connecting frame 100 and the edge of the processing space, the positioning mechanism 400 in this embodiment further includes a mounting frame 450. The mounting frame 450 is fixed to the edge of the processing space, and the locking driver 410 is connected to the mounting frame 450. Further, one side of the mounting frame 450 is fixed to the edge of the processing space, and the other side is for the positioning mechanism 400 to be mounted and connected. Thus, when positioning is required, the connecting frame 100 can be fixed to the loading port of the processing space by the positioning mechanism 400.

[0035] Furthermore, the connecting frame 100 in this embodiment also includes a connecting shaft 120, which is disposed on the rotation center line 1001 and passes through and connects to the mounting frame 450. Based on the above structural configuration, on the one hand, the assembly and movement stability of the connecting frame 100 for materials can be improved, and on the other hand, it can facilitate the positioning mechanism 400 to cooperate with the positioning hole 140 to improve the positioning effect. Specifically, in this embodiment, the connecting shaft is connected to the mounting frame 450 through a bearing.

[0036] See Figure 3 and Figure 4 As shown, the positioning mechanism 400 includes two locking actuators 410 and two locking pins 420. The two locking actuators 410 are symmetrically arranged on both sides of the connecting shaft 120, and the two locking pins 420 are arranged one-to-one with the two locking actuators 410, and can be respectively inserted into the two positioning holes 140 of the connecting frame 100. In different embodiments, to improve positioning accuracy, different numbers of locking actuators 410 and locking pins 420 can be set at different positions. Correspondingly, corresponding positioning holes 140 can also be set on the connecting frame 100. This utility model does not impose specific limitations in this regard.

[0037] Specifically, in this embodiment, the locking actuator 410 is preferably a linear motor, which can drive the locking pin 420 to move telescopically toward / away from the connecting frame 100. The positioning mechanism 400 also includes two second bushings 430 and two protective housings 440. The protective housings 440 are arranged around the locking pin 420, and the second bushings 430 are disposed between the protective housings 440 and the locking pin 420. The second bushings 430 can reduce direct friction between the shaft and other components, and can also improve the insertion accuracy of the locking pin 420. The protective housings 440 are used to form a protective structure for the locking pin 420. This utility model does not limit the specific structure and material of the protective housings 440.

[0038] The dual-mode rotary feeding device described in this embodiment also includes a control system. The rotary driver 210 and the locking driver 410 are respectively connected to the control system. In the actual production and processing process, the operator can adjust the above structure in real time through the control system, thereby improving the flexibility of the device. The operator can also preset parameters through the control system, thereby improving the automation level of the device.

[0039] In this embodiment, the protective mechanism 300 includes two assembly frames 310 and two doors 320 symmetrically arranged on opposite sides of the width direction of the connecting frame 100. The two assembly frames 310 are respectively connected to the connecting frame 100, and the two doors 320 are correspondingly arranged inside the two assembly frames 310. They are used to seal and isolate the processing space during welding processing, thereby improving the safety level of the equipment during processing.

[0040] The following describes the operation process and principle of the dual-mode rotary feeding device in this embodiment:

[0041] First, the operator installs the first component to be processed on one connecting surface 110. Then, by rotating the connecting bracket 100, the first component to be processed is moved into the processing space. After rotating 180°, the positioning mechanism 400 drives the locking pin 420 to insert into the positioning hole 140. At this time, the position of the connecting bracket 100 and the processing space is relatively fixed, and the protective mechanism 300 completely closes and stops the processing space, thus allowing welding to be performed in the processing space. At the same time, a second component to be processed is installed on another connecting surface 110. After the first component to be processed is completed, the locking pin 420 disengages from the positioning hole 140, and the rotation drive mechanism 200 rotates again by 180° to move the second component to be processed into the processing space. Repeating the above operation can achieve the purpose of "processing while loading". Example 2

[0042] See Figure 5 As shown, this embodiment provides a welding system, which includes the dual-mode rotary feeding device described in Embodiment 1 and a processing enclosure 500. The processing enclosure 500 together encloses a processing space. The dual-mode rotary feeding device is connected to the processing enclosure 500 and is located at the feed inlet of the processing space.

[0043] In summary, the dual-mode rotary feeding equipment and welding system described in this utility model provides two connecting surfaces 110 through the rotatable connecting frame 100 for dual-station feeding. Simultaneously, the connecting frame 100, in conjunction with the positioning mechanism 400, achieves precise positioning during rotation. Furthermore, the stop function of the protective mechanism 300 ensures that the connecting frame 100 completely isolates the processing space during feeding, thereby significantly improving the safety level during the feeding process. Compared to conventional feeding equipment at present, this application has advantages such as high feeding efficiency, safe and stable operation, high positioning accuracy, high controllability, and wide applicability.

However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
