Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to an automatic placement device for gear stamping and forming material discharge. Background Technology

[0002] Gears, as core components in mechanical transmission systems, are widely used in automotive gearboxes, engineering machinery drive axles, precision reducers, and industrial robots. Among the various gear manufacturing processes, stamping has become one of the mainstream methods for manufacturing small and medium module gears due to its advantages of high material utilization, fast production efficiency, and suitability for mass production. After being blanked or formed by stamping equipment, gears need to be promptly removed from the die area and arranged in an orderly manner in a tray according to a specific arrangement and posture, so as to facilitate subsequent centralized heat treatment, surface strengthening, cleaning, or automated precision machining processes.

[0003] Currently, the unloading and placement of stamped gears in the industry still generally relies on manual or semi-automatic methods. The common practice is for operators to manually or with the aid of simple clamps remove the gears one by one from the stamping die, and then insert or place them one by one into designated slots on a tray in a specific arrangement. This method has certain technical drawbacks:

[0004] First, production efficiency is low. The stamping equipment has a fast cycle time, while the frequency of manual material handling and placement is limited, making it difficult to match the stamping cycle in real time. This often leads to the stamping equipment being idle, resulting in wasted capacity. Second, placement consistency is poor. When manually placing gears, the orientation and position of the gears in the tray are difficult to standardize. Especially when gears need to enter subsequent automated stations in a specific posture, deviations in placement angle can seriously affect the gripping accuracy of downstream processes. Third, the labor intensity is high and there are safety hazards. Operators need to repeat the picking and placing actions for long periods, which easily leads to fatigue. Moreover, working in the mold opening area of ​​the stamping equipment poses a high risk of pinching injuries. Finally, the supply of empty trays and the retrieval of full trays usually rely on manual handling or separate external conveyor lines, which cannot form a compact and continuous integrated workflow with the material handling operations. This results in a large footprint and low turnover efficiency.

[0005] Therefore, there is an urgent need for an automatic material placement device for gear stamping forming that can automatically pick up and accurately place materials from stamping equipment and automatically transfer them to the material tray, in order to overcome the shortcomings of the existing technology. Summary of the Invention

[0006] This invention overcomes the shortcomings of existing technologies and provides an automatic material placement device for gear stamping and forming. It integrates automatic material tray rotation with gear placement for continuous operation, featuring a compact structure and high efficiency. The pick-and-place components automatically pick up, flip, transfer, and precisely place the material, achieving fully automated operation, eliminating safety hazards, and improving the consistency, positional accuracy, and cycle time of gear placement, providing reliable assurance for downstream automation.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] An automatic placement device for gear stamping and forming output includes a machine box, a frame is provided inside the machine box, and the frame is divided into a material tray supply area, a material tray recycling area, and a placement operation area located between the material tray supply area and the material tray recycling area.

[0009] The material tray supply area is provided with a material tray lowering component, the material tray recycling area is provided with a material tray lifting component, and a conveying component for conveying the material tray is provided between the material tray lowering component and the material tray lifting component, the conveying component conveying along a first direction;

[0010] The placement work area is equipped with a gear picking assembly and a gear unloading assembly. The gear picking assembly is used to pick up the gear from the stamping equipment and move it to the handover position with the gear unloading assembly, and hand the gear over to the gear unloading assembly. The gear unloading assembly is used to receive the gear at the handover position, move the gear to the top of the material tray and place it in the material tray located in the placement work area.

[0011] Furthermore, the gear feeding assembly includes a gripping end for gripping the gear, the gripping end being connected to a rotary drive member, the rotary drive member being used to drive the gripping end to rotate the gear to a preset angle and transfer it to the gear unloading assembly.

[0012] Furthermore, the gear-driven material handling assembly also includes a rotating rod, with the gripping end connected to one end of the rotating rod and a driven pulley connected to the other end of the rotating rod; the rotary drive component includes a drive motor and a driving pulley, with the driving pulley connected to the output end of the drive motor, and the driving pulley being connected to the driven pulley via a transmission belt; the drive motor drives the rotating rod to rotate the gripping end through the driving pulley, the transmission belt, and the driven pulley.

[0013] Furthermore, the gear feeding assembly includes an adsorption end for adsorbing gears. The adsorption end is an electromagnetic adsorption assembly. When the electromagnetic adsorption assembly is energized, it generates magnetic force to adsorb the gears and releases the gears when the power is off. The adsorption end is connected to a lifting drive component, which is used to drive the adsorption end to lift and lower to place the gears on the material tray.

[0014] Furthermore, both the tray lowering assembly and the tray lifting assembly are chain-type lifting mechanisms, and the chain-type lifting mechanism is provided with a support member; the tray is provided with hooks on both sides that cooperate with the support member, the support member is inserted into the hooks by rising to support the tray, and is released by falling out of the hooks.

[0015] Furthermore, the support member includes a longitudinal straight section located at the upper end, and a limiting section integrally formed on the side of the longitudinal straight section; the longitudinal straight section is used to insert into the hook member in the vertical direction during upward movement to support the tray, and to withdraw from the hook member in the vertical direction during downward movement to release the tray; the limiting section is used to abut against the inner side of the hook member after the longitudinal straight section is inserted into the hook member to limit further inward displacement of the tray.

[0016] Furthermore, the chassis is provided with a pick-up and drop window corresponding to the placement work area, which is used for operators to operate the gear feeding assembly and the material tray; the chassis is provided with an observation position at the docking position between the gear feeding assembly and the stamping equipment.

[0017] Furthermore, the adsorption surface of the electromagnetic adsorption component is a circular plane, and the diameter of the adsorption surface is 1mm to 3mm smaller than the root circle diameter of the gear being adsorbed.

[0018] Furthermore, the orthographic projections of the tray lowering component, the tray lifting component, and the conveying component on the horizontal plane are all within the orthographic projection range of the chassis on the horizontal plane.

[0019] Furthermore, the tray lowering component and the tray lifting component are symmetrically arranged with respect to the geometric center of the placement work area, and the center distance between them is 1 / 3 to 1 / 2 of the effective conveying length of the conveying component along the first direction.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention integrates the material tray supply area, placement area, and material tray recycling area within the same chassis. The material tray lowering component, conveying component, and material tray lifting component work together to achieve automatic material tray supply, conveying, and recycling stacking. This integrated and continuous operation of material tray circulation and gear placement reduces equipment footprint and improves production efficiency. The gear picking and unloading components work together, with the gripping end picking up material from the stamping equipment, rotating it to a preset angle via a rotary drive, and then transferring it to the electromagnetic adsorption end. The lifting drive then moves it to the top of the material tray for precise placement. The entire process requires no manual intervention, eliminating the safety hazards of manual entry into the stamping area and improving the consistency, positional accuracy, and placement rhythm of the gears, providing reliable material handling assurance for downstream automated processes.

Detailed Implementation

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] like Figures 1 to 9 As shown, this invention claims protection for an automatic material placement device for gear stamping and forming. The device is entirely housed within a casing 8, which contains a frame 9. The frame 9 is divided into three functional areas along the workflow direction: a material tray supply area, a placement area, and a material tray recycling area. The placement area is located between the material tray supply area and the material tray recycling area to facilitate the linear flow of the material trays 6.

[0035] A tray lowering assembly 1 is provided in the tray supply area for storing and releasing empty trays 6 one by one. A tray lifting assembly 2 is provided in the tray recycling area for lifting and stacking full trays 6 after gear placement. Between the tray lowering assembly 1 and the tray lifting assembly 2, a conveying assembly 3 is provided. The conveying assembly 3 extends along a first direction and is responsible for conveying empty trays 6 from the tray supply area to the placement area. After the gear placement is completed, the full trays 6 are then conveyed to the tray recycling area. Overall, the orthographic projections of the tray lowering assembly 1, the conveying assembly 3, and the tray lifting assembly 2 on the horizontal plane are all within the orthographic projection range of the chassis 8 on the horizontal plane, making the whole machine compact and space-saving.

[0036] Both the tray lowering assembly 1 and the tray lifting assembly 2 employ chain-type lifting mechanisms. Taking the tray lowering assembly 1 as an example, it includes an upper sprocket shaft and a lower sprocket shaft located at the upper and lower ends, respectively, with a double-row roller chain installed around the upper and lower sprocket shafts. Multiple support members 7 are fixedly mounted at intervals on the chain. Each support member 7 is specifically an L-shaped sheet metal part, with its vertical arm bolted to a single-side chain plate, and its horizontal arm extending inward, with the end of the horizontal arm folded upward to form a longitudinally straight section 701. Next to the longitudinally straight section 701, an integrally formed inwardly protruding limiting section 702 is formed.

[0037] Correspondingly, hook-and-loop fasteners 601 are provided on both sides of the material tray 6. Hook-and-loop slots are provided on the hook-and-loop fasteners 601. When the chain rotates and drives the support member 7 to move upwards, the longitudinal straight section 701 inserts vertically into the hook-and-loop slot of the hook-and-loop fastener 601, thereby supporting the entire material tray 6. At this time, the limiting section 702 is used to restrict further inward displacement of the material tray 6, ensuring the stability of the material tray 6 during lifting and lowering, and preventing it from shaking and falling off. When it is necessary to release the material tray 6, the chain drives the support member 7 to move downwards, and the longitudinal straight section 701 exits vertically from the hook-and-loop slot of the hook-and-loop fastener 601, so that the material tray 6 is stably placed on or below the conveying assembly 3. The structure and working principle of the material tray lifting component 2 are the same as those of the material tray lowering component 1. The only difference is that its action sequence is reversed. That is, after receiving the fully loaded material tray 6 from the lower layer, it is lifted away from the conveying component 3 by the upward action and then stacked and recycled layer by layer.

[0038] In this embodiment, the tray lowering component 1 and the tray lifting component 2 are symmetrically arranged with respect to the geometric center of the placement work area. The center distance between the two is preferably set to one-third to one-half of the effective conveying length of the conveying component 3 along the first direction, so that the overall layout of the device is balanced and the tray flow path is short and efficient.

[0039] The conveying assembly 3 is located between the tray lowering assembly 1 and the tray lifting assembly 2, and is used to carry and convey the tray 6. It includes a conveyor belt and a stepper drive mechanism. To assist in operation or maintenance, the chassis 8 has a pick-up and drop-off window 801 corresponding to the position of the placement work area. The operator can operate and adjust the gear feeding assembly 5 and the tray 6 through this window.

[0040] In the placement work area, there are gear picking assembly 4 and gear unloading assembly 5. The main function of gear picking assembly 4 is to take out the formed gear from the mold area of ​​the matching stamping equipment and move it to a handover position that docks with gear unloading assembly 5.

[0041] The gear feeding assembly 4 includes a gripping end 401 and a rotary drive component that drives its rotation. The gripping end 401 is used to directly clamp or grip the gear. The rotary drive component drives the gripping end 401 to rotate around a horizontal axis, causing the gear to rotate from its horizontal position during stamping to a preset angle for easy handover. In this embodiment, the preset angle is 180 degrees, which means that the gear can be flipped according to actual conditions.

[0042] Specifically, the gear-operated material handling assembly 4 also includes a rotating rod 402, which is a hollow shaft and is horizontally mounted on the frame 9 via a bearing seat. The gripping end 401 is coaxially fixed to the front end of the rotating rod 402 via a connecting flange. At the rear end of the rotating rod 402, a driven pulley 403 is coaxially fixed. The rotary drive includes a drive motor 404 and a drive pulley 405, which is fixed to the output shaft of the drive motor 404. The drive pulley 405 is connected to the driven pulley 403 via a transmission belt 406. During operation, the drive motor 404 outputs torque, which, after being reduced and increased in torque via the drive pulley 405, transmission belt 406, and driven pulley 403, drives the rotating rod 402 to rotate precisely around its axis, thereby causing the gripping end 401 and its gears to rotate to a preset engagement angle.

[0043] At the handover position, the gear unloading assembly 5 receives the gear from the gear picking assembly 4. The gear unloading assembly 5 includes an adsorption end 501 for adsorbing the gear. The adsorption end 501 adopts an electromagnetic adsorption component. When energized, its internal coil generates a magnetic field, and the adsorption surface generates magnetic force to firmly adsorb the gear. When de-energized, the magnetic field disappears, and the gear is released. The adsorption surface of the adsorption end 501 is a circular plane with a diameter slightly smaller than the root circle diameter of the gear to be adsorbed. The difference is controlled between 1 mm and 3 mm to ensure that the adsorption force is concentrated and effective, while avoiding the adsorption surface from exceeding the root circle and interfering with adjacent parts.

[0044] A lifting drive component 502 is connected above the adsorption end 501. The fixed end of the lifting drive component 502 is mounted on the movable seat of a horizontal displacement module, which extends along a second direction perpendicular to the first direction. After the gear feeding assembly 5 receives the gear at the junction position, the horizontal displacement module drives the entire lifting drive component 502 and the adsorption end 501 to move horizontally along the second direction above the material tray 6. Then, the lifting drive component 502 drives the adsorption end 501 to descend, placing the gear on the material tray 6. Subsequently, the electromagnetic adsorption assembly is de-energized, releasing the gear. Finally, the adsorption end 501 rises to reset, and the horizontal displacement module resets to the junction position, ready for the next work cycle.

[0045] To facilitate observation of the docking status between the device and the stamping equipment, the chassis 8 is equipped with an observation position 802 made of transparent material at the docking position between the gear feeding assembly 4 and the stamping equipment. The operator can monitor the feeding action status at any time through the observation position 802.

[0046] The working process of this device is briefly described as follows: Initially, the tray lowering component 1 operates, releasing the stacked empty trays 6 one by one onto the conveying component 3. The conveying component 3 transports the empty trays 6 along the first direction to a predetermined position in the placement area and positions them. Simultaneously, the gear picking component 4 removes the formed gears from the stamping equipment. The gripping end 401, driven by the rotary drive, flips the gears to a vertical position and moves to the handover position. After the gear unloading component 5 receives the gears at the handover position, the horizontal displacement module and the lifting drive component 502 work together to move the gears above the trays 6 and place them one by one on the trays 6. When a tray 6 is full, the conveying component 3 continues to transport the full tray 6 along the first direction to the tray recycling area, where the tray lifting component 2 lifts and stacks it for recycling. At the same time, the next empty tray 6 is sent to the placement area by the conveying component 3, and this cycle repeats continuously, realizing continuous and automatic gear unloading and placement operations.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
