Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a feeding mechanism for multiple shared dust covers. Background Technology

[0002] In the field of automated assembly, vibratory feeding mechanisms are widely used for the directional conveying and separation of workpieces. Especially for thin, easily stacked dust cover-like workpieces, achieving precise quantitative conveying and effective separation of stacked parts has always been a technical challenge in the industry. Currently common feeding mechanisms mostly use a single vibratory feeder combined with a mechanical baffle structure, which has the following significant drawbacks: Traditional mechanical baffles can only achieve physical limitation and cannot dynamically sense the stacking situation. When workpieces become stuck together in multiple layers due to static electricity or deformation, existing separation mechanisms lack active detection and multiple peeling methods, easily resulting in missed stacked parts flowing directly into the workstation. Existing feeding tracks mostly use a fixed spacing design or a manually adjustable bolt structure, which cannot dynamically adjust the width of the conveying channel according to the real-time stacking rate. In actual operation, manual adjustment is required after stopping the machine, which reduces production efficiency and makes it difficult to accurately control the throughput of stacked workpieces, often resulting in track blockage or shutdown due to overfeeding. Current separation mechanisms mostly employ specialized fixtures with threaded fasteners for installation. Changing to different fixture models requires disassembling bolts and recalibrating the positioning, resulting in lengthy changeover times and severely hindering the flexible production needs of multiple product types. Therefore, it is necessary to propose a multi-purpose dust cover feeding mechanism to solve the aforementioned problems. Utility Model Content

[0004] This utility model provides a multi-purpose shared dust cover feeding mechanism, including:

[0005] A circular vibratory machine is installed at the bottom of the entire feeding mechanism as a vibration source;

[0006] The top plate is located above the circular vibrator, connected to the circular vibrator, and driven by its vibration.

[0007] A direct vibration feeding assembly, mounted on the top plate, includes:

[0008] Linear vibratory machine, used as the power source for feeding;

[0009] An adjustable line width track is installed on the feeding path of the linear vibratory machine to limit the number of stacked workpieces;

[0010] Through-beam sensor a and through-beam sensor b are respectively installed on both sides of the adjustable linewidth track to detect the material position;

[0011] The bracket supports the linear vibratory machine and the adjustable track width.

[0012] A blocking mechanism, located on one side of the direct vibration feeding assembly, includes:

[0013] The material blocking cylinder a and the baffle a are located upstream of the linear vibrator and are used to block or release materials.

[0014] The material blocking cylinder b and the baffle b are located downstream of the linear vibrator and work in conjunction with the material blocking cylinder a to control the material conveying.

[0015] The cross shaft connector, connecting rod, and shaft are mounted on the bracket via a fixed shaft seat for transmission connection;

[0016] A vacuum nozzle transport mechanism, located on one side of the top plate, includes:

[0017] Slide cylinder a and slide cylinder b are arranged in parallel and can extend and retract alternately;

[0018] Vacuum nozzles a1, a2, a3, and a4 are installed on slide cylinders a and b and are used to adsorb and transport workpieces.

[0019] A pneumatic vibrator, located on one side of the slide cylinder a, is used to separate stacked workpieces;

[0020] The separation mechanism, located below the vacuum nozzle conveying mechanism, includes:

[0021] Vacuum nozzles b1, b2, b3, and b4 are mounted on the separation mechanism and work together with the fixture assembly to separate stacked workpieces.

[0022] Fixture assembly for receiving and positioning workpieces;

[0023] Positioning pins a and b are set on the base of the separation mechanism for quick installation of the fixture assembly;

[0024] Small base plate and large base plate, the large base plate serves as the overall support base, and the small base plate is set on the large base plate and supports the separation mechanism;

[0025] The material shortage mechanism is integrated into the top tray and is used to detect the material status of the top tray.

[0026] The return chute, located on the small base plate below the vacuum nozzle conveying mechanism, is used to recover stacked workpieces that have not been separated.

[0027] Furthermore, the width of the adjustable line width track is adjustable, which is used to adjust the width of the feeding channel according to the number of stacked workpieces.

[0028] Furthermore, the fixture assembly includes a handle, a connecting plate, and a fixture, which are quickly positioned and connected to the separation mechanism via positioning pins a and b.

[0029] Furthermore, the dimensions of vacuum nozzles a1, a2, a3, and a4 of the vacuum nozzle transport mechanism are larger than the dimensions of vacuum nozzles b1, b2, b3, and b4 of the separation mechanism.

[0030] Furthermore, the through-beam sensor c is installed at the entrance of the fixture assembly to detect whether the workpiece is in place and trigger the action of the slide cylinder b.

[0031] This utility model has the following beneficial effects: A multi-shared dust cover feeding mechanism of this utility model, through the linkage control of an adjustable linear width track and a through-beam sensor, detects the material stacking rate in real time and automatically adjusts the width of the feeding channel, avoiding track blockage or material shortage shutdowns caused by excessive stacking. Combined with feedback from a vacuum pressure sensor and multiple sets of through-beam sensors, a closed-loop control is formed, ensuring precise coordination between the vacuum nozzle handling mechanism and the separation mechanism, actively identifying and peeling stacked workpieces, and preventing undetected stacked parts from flowing into the workstation. The vacuum nozzle handling mechanism uses a large-size vacuum nozzle in conjunction with a small-size vacuum nozzle in the separation mechanism. The size difference generates an adsorption force gradient, which, combined with the active shaking of a pneumatic vibrator, achieves multi-stage peeling of stacked workpieces. The fixture assembly of the separation mechanism and the vacuum nozzle form a reverse air blowing mechanism. When a workpiece is detected simultaneously in both the nozzle and the fixture, instantaneous reverse air blowing removes the stacking, improving the separation success rate. The fixture assembly, through the engagement of positioning pins with the inclined positioning surface of the separation mechanism, enables screwless, rapid installation, reducing single-changeover time to the second level and meeting the flexible production needs of various dust covers. The adjustable linewidth track's width adjustment range covers different workpiece specifications. Combined with the universal fixture assembly, it supports multiple dust cover models sharing the same feeding system, significantly reducing equipment modification costs. The blocking mechanism adopts a rigid transmission structure with a cross-shaft connector and connecting rod, eliminating the action delay in traditional cylinder linkage, ensuring the synchronization accuracy of the blocking cylinder, and preventing material accumulation or gaps. The return chute and the in-pan shortage mechanism form a complete material circulation system, automatically recovering unseparated workpieces and replenishing missing materials, reducing manual intervention frequency and improving the stability of continuous equipment operation.

Detailed Implementation

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0041] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0042] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions has been enlarged, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0043] Please see Figures 1 to 6This utility model provides a multi-purpose dust cover feeding mechanism, the overall structure of which consists of a circular vibrator 1, a top plate 2, a linear vibrating feeding assembly 3, a blocking mechanism 4, a vacuum nozzle conveying mechanism 5, a separation mechanism 6, a small base plate 7, a large base plate 8, a material shortage mechanism 9, and a return trough 10. The circular vibrator 1, as the vibration source, is set at the bottom of the feeding mechanism, and the top plate 2 is installed above it. The top plate 2 guides the workpiece to the linear vibrating feeding assembly 3 through vibration. The linear vibrating feeding assembly 3 includes a linear vibrator 301, an adjustable line width track 302, a through-beam sensor a 303, a through-beam sensor b 304, and a bracket 305. The linear vibrator 301 is fixed on the top plate 2, and the adjustable line width track 302 is installed on the feeding path of the linear vibrator 301. The number of stacked workpieces is limited by manually or automatically adjusting the track width. The bracket 305 supports the linear vibrator 301 and the adjustable line width track 302 to ensure feeding stability. Through-beam sensors a303 and b304 are located at the inlet and outlet sides of the adjustable linewidth track 302, respectively, to detect the workpiece position in real time and control the blocking mechanism 4 in conjunction with it to achieve dynamic flow restriction. The blocking mechanism 4 consists of a blocking cylinder a401, a baffle a402, a blocking cylinder b403, a baffle b404, a cross shaft connector 408, a connecting rod 407, a shaft 409, and a fixed shaft seat 410. The blocking cylinder a401 and the baffle a402 are located upstream of the linear vibrator 301 and initially extend to block the workpiece. The blocking cylinder b403 and the baffle b404 are located downstream. When the through-beam sensor a303 detects workpiece accumulation, the blocking cylinder a401 retracts and the blocking cylinder b403 extends. The rigid transmission of the cross shaft connector 408 and the connecting rod 407 ensures synchronous action and avoids material accumulation or gaps.

[0044] The vacuum nozzle transport mechanism 5 is located on one side of the top plate 2 and includes a slide cylinder a501, a slide cylinder b502, vacuum nozzles a1503, a2504, a3505, a4506, and a pneumatic vibrator 507. Slide cylinders a501 and b502 are arranged in parallel and extend and retract alternately, driving vacuum nozzles a1 to a4 to adsorb workpieces. Each vacuum nozzle is connected to a vacuum pressure sensor; if an abnormal adsorption force (such as layering) is detected, the pneumatic vibrator 507 activates to shake and remove excess workpieces. The separation mechanism 6 is located below the vacuum nozzle transport mechanism 5 and includes vacuum nozzles b1601, b2602, b3603, b4604, a fixture assembly 609, and positioning pins a610 and b611. The fixture assembly 609 is quickly installed on the inclined positioning surface of the separation mechanism 6 via positioning pins a610 and b611, without the need for bolt fixing. The vacuum nozzles b1 to b4 are smaller than the vacuum nozzles a1 to a4, forming an adsorption force gradient. When the workpiece is placed on the fixture assembly 609, the vacuum nozzles b1 to b4 adsorb the bottom of the workpiece. If stacking is detected, reverse air blowing is used to remove it. The small base plate 7 and the large base plate 8 form a double-layer support structure. The large base plate 8 serves as the overall base, and the small base plate 7 is fixed on the large base plate 8 and supports the separation mechanism 6. The material shortage mechanism 9 is integrated in the top plate 2. It monitors the material inventory through a photoelectric sensor and triggers material replenishment. The return trough 10 is set on the small base plate 7 to collect the stacked workpieces that have not been separated and send them back to the top plate 2 for reprocessing through an air blowing pipe.

[0045] The working principle of the feeding mechanism is as follows: After the workpiece is put into the top platen 2, it is guided by the circular vibrator 1 to the linear vibrating feeding assembly 3. The linear vibrator 301 drives the workpiece to be conveyed forward along the adjustable line width track 302. The through-beam sensors a303 and b304 monitor the position of the workpiece in real time. When the stacking rate is detected to be too high, the adjustable line width track 302 is automatically widened to reduce the stacking amount. The blocking mechanism 4 controls the blocking cylinders a401 and b403 in linkage according to the sensor signal to ensure orderly material conveying. The sliding cylinders a501 and b502 of the vacuum nozzle conveying mechanism 5 extend alternately. After the vacuum nozzles a1 to a4 adsorb the workpiece, they move to the top of the fixture assembly 609. If the vacuum pressure sensor detects stacking, the pneumatic vibrator 507 vibrates to peel off the excess workpiece. The vacuum nozzles b1 to b4 of the separation mechanism 6 adsorb the bottom of the workpiece and, in combination with the reverse blowing mechanism, thoroughly remove the residual stacking. The unseparated workpieces are returned to the top platen 2 for recycling through the return chute 10. The material shortage mechanism 9 monitors the material level in the top tray 2 in real time. When material is insufficient, it triggers an alarm or automatically replenishes the material to ensure continuous production.

[0046] The beneficial effects of this utility model are reflected in the following aspects: First, the adjustable linewidth track 302 and the linkage control of the through-beam sensors a303 and b304 enable dynamic adjustment of the feeding channel width, solving the problem of easy blockage or insufficient material in traditional fixed tracks; Second, the size difference design of vacuum nozzles a1 to a4 and b1 to b4 and the active peeling of pneumatic vibrator 507 significantly improve the success rate of stacking separation; Third, the fixture assembly 609 achieves second-level model change through the tilt positioning of positioning pins a610 and b611, supporting the sharing of multiple dust cover models, such as fixture one 703, fixture two 704, and fixture three 705; Fourth, the rigid transmission structure of the blocking mechanism 4 and the closed-loop material circulation of the return trough 10 ensure stable and efficient feeding process and reduce manual intervention. This utility model is particularly suitable for automated feeding scenarios of thin sheet dust cover workpieces, combining the advantages of high precision, high flexibility, and low maintenance costs.
