A master stator storage mechanism

Abstract

This application discloses a main stator storage mechanism, including: a conveyor line, a pre-storage guide rail, first and second pushing devices, a storage box, and a transfer assembly. The pre-storage guide rail is arranged side-by-side on one side of the conveyor line, is straight, and has a feed inlet at one end. When the downstream processing equipment fails, the first pushing device pushes the main stator on the conveyor line laterally to the feed inlet; the second pushing device then pushes it into the pre-storage guide rail, arranging multiple main stators in a row. The transfer assembly can absorb and move the entire row of main stators into the storage box for temporary storage, ensuring the continuous operation of the upstream stamping process. After the equipment is repaired, the transfer assembly can also move the main stator from the storage box back to the conveyor line to resume production. This system realizes automatic buffering and return of the main stator, effectively improving production continuity and equipment utilization, and avoiding a complete line shutdown due to a local failure.

Description

Technical Field

[0001] This utility model belongs to the field of production automation technology, and in particular relates to a main stator material storage mechanism. Background Technology

[0002] In existing technologies, the main stator welding process typically adopts an integrated operation mode, covering processes such as stamping, shaping, short-circuit ring processing, insertion, and welding. Among them, the main stator stamping process relies on high-speed punch presses to achieve rapid material output, processing dozens of workpieces per minute. However, due to the susceptibility of welding equipment to sudden failures and the uncertainty of repair time, when the welding machine stops, the linked punch press must also stop, causing the entire production line to be interrupted, relevant operators to be idle, resulting in idle human resources and low production efficiency. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide a main stator material storage mechanism to solve the technical problem of punch press shutdown and production line interruption caused by welding equipment failure in integrated operation mode, resulting in resource waste and low efficiency.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] A main stator storage mechanism, characterized in that it comprises: a conveyor line, configured for transporting main stators backward; a pre-storage guide rail, arranged side-by-side on one side of the conveyor line, the pre-storage guide rail being a straight structure with one end closed and the other end having a feed inlet, the width of which matches the main stator; a first pushing device, horizontally movable and arranged perpendicular to the conveyor line, and opposite to the feed inlet, used to push the main stator on the conveyor line to a position collinear with the feed inlet when the downstream processing equipment fails; a second pushing device, horizontally movable and arranged collinear with the pre-storage guide rail, and opposite to the feed inlet, used to push the main stator located at the feed inlet into the pre-storage guide rail, so that multiple main stators are arranged in a row within the pre-storage guide rail; a storage box, disposed on the side of the pre-storage guide rail away from the conveyor line; and a transfer assembly, movably disposed between the pre-storage guide rail and the storage box, capable of adsorbing an entire row of main stators on the pre-storage guide rail and placing them into the storage box, or adsorbing an entire row of main stators from the storage box and placing them onto the conveyor line after the downstream processing equipment is repaired, so that they can continue to be transported backward by the conveyor line.

[0008] By installing pre-stored guide rails with a specific structure on the side of the conveyor line, and coordinating the operation of the first and second pushing devices, storage boxes, and transfer components, a highly efficient automated buffer storage system is constructed. When downstream processing equipment malfunctions, this system can immediately transfer the main stators on the conveyor line laterally to the entrance of the pre-stored guide rails, then push them into the guide rails for neat arrangement. Finally, the transfer components move the rows of main stators as a whole to a large-capacity storage box for temporary storage. This process ensures that the upstream stamping equipment can continue to operate during welding machine maintenance, effectively avoiding production line interruptions and personnel downtime. After the equipment is repaired, the system can automatically put the temporarily stored main stators back onto the conveyor line, quickly restoring production rhythm. The overall solution significantly improves the continuity of the production line, equipment utilization, and overall capacity, solving the efficiency bottleneck problem caused by rigid connections between processes.

[0009] In some embodiments, the first pushing device is a cylinder and the driving end is provided with a first pushing block. A limiting groove is opened on one side of the conveyor line at the corresponding position of the pre-stored guide rail feed port, which matches the shape of the first pushing block to limit the moving direction of the first pushing block.

[0010] By using a cylinder drive combined with a push block of a specific shape and a limiting groove, the movement trajectory of the first push device when pushing the main stator laterally is ensured to be precise and stable, effectively preventing deviation or jamming during the pushing process. This ensures that the main stator can be accurately and smoothly transferred laterally to the pre-stored feed port position of the guide rail, improving the reliability and positioning accuracy of the action.

[0011] In some embodiments, the second pushing device is a cylinder and the driving end is provided with a vertically extending second pushing block.

[0012] The vertically extending push block driven by a cylinder provides a stable and concentrated thrust to push the main stator into the pre-stored guide rail in a straight line from the feed port, ensuring that the main stator is upright in the initial stage of entering the guide rail and is not prone to tilting or flipping.

[0013] In some embodiments, the two sides of the pre-stored guide rail are two guide rail limiting walls, wherein the guide rail limiting wall away from the first pushing device is longer than the other guide rail limiting wall, which can limit the movement of the main stator pushed by the first pushing device to the position of the feed inlet.

[0014] The asymmetrical guide rail limiting wall design cleverly intercepts and guides the main stator that is pushed laterally, ensuring that the main stator can accurately stop at the predetermined feed inlet position. This creates conditions for the second pushing device to smoothly push it into the guide rail, preventing the main stator from missing the feed inlet due to inertia or positional deviation.

[0015] In some embodiments, a longer guide rail limiting wall extends to the second pushing device, which can guide the drive end of the second pushing device to move toward the feed port of the pre-stored guide rail.

[0016] The extended guide rail limiting wall not only positions the main stator, but also provides a reliable movement guide for the drive end of the second push device, so that the pushing action always proceeds along a predetermined straight path. This further enhances the stability and accuracy of pushing the main stator into the pre-stored guide rail and reduces the risk of failure caused by the shaking or deviation of the push mechanism itself.

[0017] In some embodiments, the transfer assembly includes a sliding module and a transfer device. The sliding module extends along the length of the storage box, and the transfer device is a vertical cylinder with an adsorption plate at the drive end. The length of the adsorption plate matches the width of the storage box and is used to adsorb the entire row of main stators.

[0018] Precise horizontal positioning is achieved through a sliding module, combined with a wide adsorption plate driven by a vertical cylinder, enabling the transfer component to efficiently and smoothly adsorb and transfer an entire row of main stators in one go. This greatly improves the efficiency of material flow between the pre-stored guide rail and the storage box, while avoiding the inefficiency and workpiece damage that may be caused by handling each item individually, ensuring the neatness of storage and the convenience of retrieval.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] This utility model provides a main stator material storage mechanism, the core of which lies in constructing a highly efficient automated buffer storage system. This structure first includes a continuously operating conveyor line 1, which is typically composed of a motor-driven roller or belt, responsible for continuously transporting the main stator 7 to the subsequent welding process. Notably, a pre-storage guide rail 2 is arranged side-by-side on one side of the conveyor line 1. This pre-storage guide rail 2 has a straight structure, with one end near the conveyor line 1 open to form a feed inlet 21, while the opposite end remains closed. The internal width of the pre-storage guide rail 2 is optimized to match the external dimensions of a single main stator 7, thus ensuring the smooth passage of the main stator 7 while effectively restricting its degrees of freedom.

[0028] Furthermore, to facilitate timely transfer of workpieces in the event of a malfunction in the downstream welding equipment, the system is equipped with a first pushing device 3. This device is installed on the side of the conveyor line 1 away from the pre-storage guide rail 2, and its driving direction is set perpendicular to the transmission direction of the conveyor line 1, with its axis of motion precisely aligned with the feed inlet 21 of the pre-storage guide rail 2. Thus, when temporary storage is required, the first pushing device 3 can extend horizontally, pushing the main stator 7 traveling on the conveyor line 1 laterally, causing it to detach from the conveyor line 1 and accurately reach a preparatory position collinear with the feed inlet 21.

[0029] Based on this, the system also includes a second pushing device 4. This device is located on the extension line of the pre-stored guide rail 2, collinear with the pre-stored guide rail 2, and its front end is also directly opposite the feed inlet 21 of the pre-stored guide rail 2. Its function is to horizontally push the main stator 7 into the interior of the pre-stored guide rail 2 when the first pushing device 3 pushes it to the ready position. By repeatedly performing this action, multiple main stators 7 can be closely arranged within the pre-stored guide rail 2, forming a neat row.

[0030] Preferably, a large-capacity storage box 5 is installed on the side of the pre-stored guide rail 2 away from the conveyor line 1. This storage box 5 is used to centrally store multiple rows of pre-arranged main stators 7, and its capacity can be designed according to the actual production cycle and expected maintenance time.

[0031] To enable the automatic flow of materials between the pre-storage guide rail 2 and the storage box 5, a transfer component 6 is specially designed for the system. This transfer component 6 spans the area between the pre-storage guide rail 2 and the storage box 5, and has two core functions: first, it can pick up the entire row of main stators 7 already formed on the pre-storage guide rail 2 in one go, and then place them stably into the storage box 5 for temporary storage; second, after repair by the welding equipment at the rear, it can reverse the operation, that is, pick up and extract the entire row of main stators 7 from the storage box 5, and accurately place them back onto the conveyor line 1, which will then drive them backward, allowing production to resume quickly.

[0032] Specifically, the storage mechanism also includes a control system, which is electrically connected to the downstream processing equipment (such as a welding machine). When a fault signal is received from the downstream processing equipment, the control system controls the first pushing device 3 and the second pushing device 4 to operate sequentially, pushing the main stators 7 into the pre-stored guide rail 2 for arrangement. When the pre-stored guide rail 2 is full of main stators 7, a sensor (such as a position sensor) detects and feeds back a signal to the control system, which then activates the transfer assembly 6 to transfer the entire row of main stators 7 into the storage box 5. Conversely, when a repair signal is received, the control system controls the transfer assembly 6 to move the main stators 7 from the storage box 5 back to the conveyor line.

[0033] In a more preferred embodiment, the first pushing device 3 specifically uses a cylinder as its power source. A first pushing block 31 is fixedly connected to the end of the piston rod of the cylinder. The cross-sectional shape of the pushing block is typically designed to be rectangular or trapezoidal. Specifically, a limiting groove 11 is specially formed on the side of the conveyor line 1, corresponding to the feed inlet 21 of the pre-stored guide rail 2. The shape of this limiting groove 11 matches the front end shape of the first pushing block 31. When the cylinder pushes, the first pushing block 31 embeds itself in the limiting groove 11 and moves along its trajectory. This structure provides reliable guidance for the lateral pushing process, effectively preventing the pushing block from swaying during its stroke, thereby ensuring that the main stator 7 is accurately pushed to the designated position at the inlet of the pre-stored guide rail 2.

[0034] The second pushing device 4 is also preferably driven by a cylinder. A vertically extending second pushing block 41 is mounted on the end of the piston rod of the cylinder. The vertical height of this pushing block is usually adapted to the height of the main stator 7, so that it can push the end face of the main stator 7 with a large contact area, thereby providing a smooth linear thrust when pushing the main stator 7 into the pre-stored guide rail 2, and avoiding tilting or jamming of the workpiece at the inlet.

[0035] The structure of the pre-stored guide rail 2 consists of two guide rail limiting walls 22 on both sides. A key design feature is that the guide rail limiting wall 22 on the side furthest from the first pushing device 3 is designed to be significantly longer than the guide rail limiting wall 22 on the side closer to the first pushing device 3. This asymmetrical structure ensures that the main stator 7, coming from the lateral direction, first contacts the longer limiting wall, which acts as a guide and interceptor, ultimately confining the main stator 7 to the precise feed inlet 21 position, preparing it for the subsequent linear push by the second pushing device 4.

[0036] Furthermore, the aforementioned longer guide rail limiting wall 22 extends further forward, covering the active area of ​​the second pushing device 4. In this way, the extended section not only guides the main stator 7 but also provides lateral support and guidance for the reciprocating motion of the drive end of the second pushing device 4 itself (e.g., the second pushing block 41), ensuring the straightness of the path of the second pushing device 4 when performing the pushing action and enhancing the stability of the entire pushing process.

[0037] For the transfer component 6, a typical implementation includes a sliding module 61 and a transfer device 62. The sliding module 61 typically uses a linear guide rail and a slider in combination, with its installation direction parallel to the length direction of the storage box 5. A motor drives a screw to rotate, and the screw and slider are threaded together, allowing the entire transfer device 62 to move precisely along this direction to above any row of positions on the pre-stored guide rail 2 or the storage box 5. The transfer device 62 is fixed to the slider of the sliding module 61 by a mounting plate, and its main body is a vertical cylinder. The piston rod of the vertical cylinder extends downward, and its end is connected to an adsorption plate 63 with a length matching the width of the storage box 5. The lower surface of the adsorption plate 63 is covered with vacuum chucks or electromagnetic chucks, enabling it to simultaneously adsorb an entire row of main stators 7. Through the precise positioning of the sliding module 61 and the raising and lowering of the vertical cylinder, combined with the adsorption and release of the adsorption plate 63, the efficient and lossless transfer of an entire row of main stators 7 between the pre-stored guide rail 2 and the storage box 5 can be achieved.

[0038] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
