The tray has a relatively complex positioning structure. Each pump cover needs to be placed accurately to avoid grabbing errors. The labor intensity is high, the efficiency is low, and the labor cost is high. Summary of the Invention

DETAILED DESCRIPTION

[0031] It should be noted that the following detailed descriptions are exemplary and are 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 those skilled in the art to which the present application belongs.

[0032] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0033] like Figures 1 to 10As shown, a pump cover loading equipment includes multiple parallel chain conveyors 100 for conveying pump covers, and a picking device 400 for grabbing the pump cover 200 on the chain conveyor is provided in front of the chain conveyor 100, and the picking device 400 includes a horizontal linear slide 410 arranged in the transverse direction, and a rotating positioning platform 300 for placing the pump cover is provided on the rear side of one end of the horizontal linear slide; a pair of correcting plates 110 are provided on the left and right sides of the middle section of the chain conveyor 100, and a correcting channel 120 is left between the correcting plates 110 on both sides for the pump cover opening 210 of the pump cover 200 to pass through the middle; the discharge end of the chain conveyor is provided with a positioning cross bar 130 which can move forward and backward and is perpendicular to the length direction of the chain conveyor, and a V-shaped positioning groove 131 is provided on the rear side of the positioning cross bar 130, and the V-shaped positioning groove 131 is longitudinally aligned with the correcting channel 120. The staff placed multiple pump covers on the feeding end (i.e., the rear end) of the chain conveyor 100, with the pump cover opening facing upwards. The chain conveyor 100 drove the pump cover to move forward. The height of the correcting plate 110 was higher than the height of the pump cover body, but lower than the height of the pump cover opening. The correcting plate 110 adjusted the pump cover opening of the pump cover to the middle position. When the pump cover reached the discharging end (i.e., the front end) of the chain conveyor 100, the chain conveyor 100 stopped moving, and the cross bar moved backwards to adjust the front and rear positions of the pump cover, so that the pump cover opening of the pump cover was in the specified position, which was convenient for the picking device 400 to grab the pump cover through the pump cover opening to ensure that the pump cover opening The position is precise. After the material picking device 400 grabs the pump cover, it is placed on the rotating positioning table. The orientation of the pump cover is adjusted by the rotating positioning table to facilitate the robot system to grab it (the robot system belongs to the prior art and does not belong to the scope of the present invention. The robot system has a clamp for grabbing the pump cover); the pump cover loading equipment of the present invention is reasonably designed and easy to use. A worker can operate multiple chain conveyors 100 by one person, and can place multiple pump covers on the chain conveyor 100 at one time. It is highly efficient and does not require manual positioning, realizing assembly line loading, reducing labor intensity, saving time and effort, and saving labor costs.

[0034] In this embodiment, in this embodiment, the chain conveyor 100 is provided with a material blocking mechanism 140 in front of the deviation correction channel 120, and the material blocking mechanism 140 includes a lifting plate 142 driven by a first cylinder 141 to lift and lower, and a V-shaped material blocking plate 143 is connected to the rear of the lifting plate, and the V-shaped material blocking plate is longitudinally aligned with the deviation correction channel, and a proximity switch B144 for sensing the pump cover is provided above the V-shaped material blocking plate, and a fixed bracket 145 for installing the first cylinder 141 is fixedly connected to the chain conveyor 100, and a photoelectric switch B146 for sensing the pump cover opening of the pump cover is provided on both sides of the front of the fixed bracket of the chain conveyor 100; the material blocking mechanism is used to control the pump covers to pass one by one, and when the cross bar is aligned with the pump cover, the pump cover opening is sensed by the cross bar. When the front pump cover is positioned, the material blocking mechanism blocks the next pump cover to avoid affecting the positioning of the previous pump cover; the first cylinder 141 drives the lifting plate 142 to descend, so that the V-shaped material blocking plate 143 blocks the pump cover opening of the pump cover, while ensuring that the pump cover opening is still in the middle position and will not be offset; when the lifting plate descends, the proximity switch B144 senses whether there is a pump cover blocked. When no pump cover is sensed, the alarm is used to remind the workers to load the material; after the lifting plate is lifted, the pump cover passes through the material blocking mechanism, and the opposing photoelectric switch 146 is used to sense whether the pump cover has passed the material blocking mechanism. If the pump cover has passed, the first cylinder 141 is controlled to act. The first cylinder is controlled by the first solenoid valve, and the lifting plate descends to block the next pump cover.

[0035] In this embodiment, the rear end of the correction plate 110 is provided with a beveled edge, and a V-shaped inlet 150 is formed between the beveled edges of the correction plates on both sides. The function of the V-shaped inlet 150 is to ensure that the pump cover opening is smoothly guided into the correction channel 120.

[0036] In this embodiment, a second cylinder 160 is installed on the side of the discharge end of the chain conveyor 100 to drive the positioning cross bar to move forward and backward. The second cylinder is controlled by a second solenoid valve, and the positioning cross bar is connected to the telescopic rod of the second cylinder through a connecting plate. After the positioning cross bar completes the positioning work, the second cylinder drives the positioning cross bar to move forward to avoid affecting the robot arm's grasping of the pump cover.

[0037] In this embodiment, protective baffles 170 are provided on both sides and at the front and rear ends of the chain conveyor.

[0038] In this embodiment, a turntable 310 for placing a pump cover is provided in the middle of the rotating positioning table 300, and a positioning boss 311 adapted to the pump cover opening of the pump cover is provided in the center of the turntable 310. A proximity switch A320 is provided on the rotating positioning table, which is located next to the turntable and is used to sense the edge of the pump cover farthest from the pump cover opening; the material taking device 400 places the pump cover on the turntable 310, and the pump cover opening of the pump cover cooperates with the positioning boss on the turntable. The position of the pump cover is adjusted by rotating the turntable. When the proximity switch A320 senses the edge of the pump cover farthest from the pump cover opening (i.e. Figure 1 When the pump cover is positioned at position A in the middle, it indicates that the pump cover has been adjusted into place, and the turntable stops rotating, waiting for the robot system to grab the pump cover. No manual positioning is required, which saves time and effort, is highly efficient, simplifies the positioning structure, avoids interference between the complex positioning structure and the robot system, and is conducive to rapid loading.

[0039] In this embodiment, a supporting foot is connected to the bottom of the rotation positioning platform 300, and a rotation motor 330 for driving the turntable is installed at the bottom of the rotation positioning platform. The main shaft of the rotation motor passes through the rotation positioning platform upward and is connected to the lower side of the rotation.

[0040] In this embodiment, a limit baffle 350 is provided on the rotary positioning platform 300 beside the proximity switch to support the edge of the pump cover farthest from the pump cover opening. The limit baffle is driven to extend and retract by the cylinder 360. The limit baffle 350 is used to prevent the pump cover from rotating too much. When the pump cover is placed on the turntable, the cylinder drives the limit baffle to extend and the turntable rotates. After the pump cover is adjusted into place, the proximity switch A320 senses the edge of the pump cover farthest from the pump cover opening (i.e. Figure 1 At the same time, the limit baffle also presses against this part, and then the turntable stops rotating, and the cylinder drives the limit baffle to retract.

[0041] In this embodiment, the upper end of the positioning boss 311 is tapered with a smaller top and a larger bottom, so that the positioning boss can be smoothly inserted into the pump cover opening of the pump cover.

[0042] In this embodiment, the rotary positioning table is provided with a through-type photoelectric switch A340 located next to the turntable for sensing the pump cover opening on the pump cover; when the through-type photoelectric switch A340 senses that the pump cover has been placed in place, it delays for a predetermined time (controlled by a timing module to leave time for the material-taking device 400 to release), and transmits a signal through the controller to the third solenoid valve controlling the third cylinder, so that the cylinder drives the limit baffle to extend, and at the same time controls the operation of the rotary motor to adjust the position of the pump cover.

[0043] The proximity switch B144, the through-beam photoelectric switch B146, the through-beam photoelectric switch A340, and the proximity switch A320 are all connected to the signal input end of the controller, and the signal output end of the controller is connected to the rotating motor, each solenoid valve, the motor of the chain conveyor, and each servo motor of the material taking device; the specific circuit structure and control principle belong to the existing technology and will not be elaborated here. The present invention only applies it to the pump cover rotation positioning platform.

[0044] In this embodiment, a vertical linear slide 420 is installed on the horizontal slide of the horizontal linear slide 410, a longitudinal linear slide 430 extending backward is installed on the vertical slide of the vertical linear slide, and a pneumatic three-jaw chuck 440 is installed on the lower part of the longitudinal slide of the longitudinal linear slide, and the pneumatic three-jaw chuck is controlled by a fourth solenoid valve; the horizontal linear slide, the vertical linear slide and the longitudinal linear slide are respectively controlled by their own servo motors; the material picking device grabs the pump cover on each chain conveyor by horizontal movement and then places it on the rotary positioning table.

[0045] A working method of the automatic pump cover feeding device as described above comprises the following steps:

[0046] (1) Workers place pump covers at the feed end of each chain conveyor. Multiple pump covers can be placed on each chain conveyor.

[0047] (2) The chain conveyor transports the pump cover to the discharge end. During the conveying process, the left and right positions of the pump cover are pre-adjusted by the deviation correction channel so that the pump cover opening of the pump cover is in the middle of the chain conveyor. When the pump cover reaches the discharge end, the chain conveyor stops and the front and rear positions of the pump cover are adjusted by the positioning cross bar so that the pump cover opening of the pump cover is in a designated position that is convenient for the material removal device to grab. At this time, the blocking mechanism blocks the last pump cover on the chain conveyor.

[0048] (3) The reclaiming device moves to each chain conveyor and uses a pneumatic three-jaw chuck to grab the pump cover at the discharge end of the chain conveyor;

[0049] (4) The picking device moves to the rotary positioning table, places the pump cover on the turntable of the rotary positioning table, releases the pneumatic three-jaw chuck, and the picking device moves to grab the next pump cover;

[0050] (5) The turntable on the rotary positioning table rotates, adjusts the position of the pump cover, and the turntable stops rotating;

[0051] (6) The robotic system removes the pump cover from the rotary positioning table, completing the loading of a pump cover.
