Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a feeding device for columnar workpieces. Background Technology

[0002] Currently, automated feeding is not possible in high-precision hearing aid welding stations, which still rely on manual welding under a microscope, making it a labor-intensive process. When the diameter of silver-plated beryllium copper wire is only 0.12mm, the traditional continuous feeding method of removing the enamel coating and cutting is unusable. It must be cut to the required length, the insulation layer removed using a high-temperature salt bath, then desalted with warm water, dried, and manually welded. In the medical industry, production lines for assembling and testing fine tubular parts often use multiple U-shaped troughs and pusher plates for feeding. This method requires a large quantity of material per trough, and the placement and recycling of raw materials are inconvenient. The raw materials for the assembled products are constantly subjected to friction, vibration, or disturbance in the hopper, easily causing damage and waste. After the tubular parts are lifted into the feeding trough, they need to be flipped using other devices, a complex process with high requirements for part fit and processing, resulting in high costs and poor equipment stability. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a feeding device for columnar workpieces to solve the technical problems of high manufacturing cost and poor equipment stability in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides a feeding device for cylindrical workpieces, comprising:

[0005] The first module includes a base plate and a base for holding the workpiece to be processed;

[0006] The second module includes a support frame mounted on the base plate, a first drive unit mounted on the support frame, a horizontal slide rail, and a horizontal sliding frame, the horizontal sliding frame sliding along the horizontal slide rail under the drive of the first drive unit;

[0007] The hopper module includes a mounting plate, forks, a rotating shaft, a lever arm, a disturbance wheel, and a wheel fixing component. The mounting plate is mounted on a horizontal sliding frame via a clamping component. The forks are connected to one end of the lever arm. The rotating shaft passes through a corresponding hole on the lever arm and is connected to the mounting plate. The wheel fixing component connects the disturbance wheel to the mounting plate near the forks.

[0008] The third module includes a bracket mounted on the base plate;

[0009] The material taking module is connected to the support, and the material taking module comprises a material taking part arranged close to the fork.

[0010] In an embodiment of the present application, the first module comprises a second driving part, and the second driving part drives the base to rise or fall along the direction perpendicular to the base plate.

[0011] In an embodiment of the present application, the material bin module further comprises a third driving part, and the third driving part drives the lever arm to make lever movement around the rotation shaft, thereby driving the fork to rise or fall.

[0012] In an embodiment of the present application, the end of the fork away from the lever arm is provided with a U-shaped paw, and the U-shaped opening in the middle of the paw is aligned with the disturbance rotating wheel, so that when the paw rises with the fork, the disturbance rotating wheel partially extends into the U-shaped opening to prevent the columnar workpiece placed on the fork from falling off the paw; when the bin module is in a working state, the gap between the paw and the disturbance rotating wheel in the vertical direction is just enough to allow a columnar workpiece to fall from the paw to the material taking part.

[0013] In an embodiment of the present application, the material bin module further comprises a fourth driving part for driving the disturbance rotating wheel to rotate around the central shaft thereof; when the bin module is in a working state, the rotation of the disturbance rotating wheel drives other columnar workpieces stacked on the fork to be pushed back to the paw.

[0014] In an embodiment of the present application, the third module further comprises a vertical sliding rail and a vertical sliding frame installed on the support, a fifth driving part, a rotating mechanism and a sixth driving part, and the fifth driving part drives the vertical sliding frame to move along the vertical sliding rail.

[0015] In an embodiment of the present application, the material taking part of the material taking module comprises an upper material taking part and a lower material taking part, the upper material taking part is provided with a plurality of grooves for accommodating columnar workpieces, and the lower material taking part is provided with a plurality of material taking holes corresponding to the grooves, and the top opening of each groove is only large enough to allow one columnar workpiece to fall into it.

[0016] In an embodiment of the present application, the material taking module further comprises a vacuum suction part arranged at the end of the upper material taking part, the upper material taking part is provided with a vacuum suction structure in communication with the vacuum suction part, and the inner wall of each groove is provided with a vacuum suction port in communication with the vacuum suction structure.

[0017] In an embodiment of the utility model, the stock bin module further comprises a fourth driving member for driving the disturbing runner to rotate around its central axis. When the stock bin module is in working state, the upper taking member is located in the U-shaped opening in the middle of the paw and faces the disturbing runner. The top surface of the upper taking member provided with the groove is higher than the top surface of the paw, and the gap between the top surface of the upper taking member and the bottom surface of the disturbing runner is smaller than the diameter of the columnar workpiece in the vertical direction. When the columnar workpiece moves along the upper taking member in the horizontal direction under the driving of the horizontal sliding frame, the rotation of the disturbing runner makes the columnar workpieces on the top surface of the upper taking member move along with the stock bin module on the top surface of the upper taking member in the moving direction of the stock bin module. Only when the columnar workpieces hit a groove during the movement, one columnar workpiece will fall into the groove and be adsorbed in the groove, so as not to continue moving on the top surface of the upper taking member with the disturbing runner.

[0018] In an embodiment of the utility model, the rotating mechanism is connected between the upper taking member and the sixth driving member. When the sixth driving member drives the rotating mechanism to drive the upper taking member to rotate 90 degrees around the axis of the rotating mechanism, the surface of the upper taking member provided with the groove is perpendicular to the surface of the lower taking member provided with the taking hole. Thus, the groove of the upper taking member is aligned with the corresponding taking hole, so that the columnar workpiece accommodated in each groove falls into the corresponding taking hole.

[0019] In an embodiment of the utility model, the taking member module further comprises a plurality of guide pipes and sockets. One end of each guide pipe is communicated to the corresponding taking hole, and the other end is communicated to the corresponding socket.

[0023] The disturbing runner is connected to the position corresponding to the paw of the mounting plate through the runner fixing member. The disturbing runner is connected with the runner driving member.

[0024] The opening is aligned with the disturbing runner, so that when the paw is lifted with the fork, the disturbing runner partially enters the opening to prevent the columnar workpiece placed on the fork from falling off the paw.

[0025] In one embodiment of this utility model, when the feeding structure is in a working state in conjunction with the picking member, the picking member is located in the opening of the claw and faces the disturbance wheel. The top surface of the picking member with several grooves is higher than the top surface of the claw, and the vertical gap between the top surface of the picking member and the bottom of the disturbance wheel is a predetermined value so that a predetermined number of columnar workpieces can pass through the gap. When the feeding structure moves along the picking member with columnar workpieces under the drive of the moving component, the rotation of the disturbance wheel causes several columnar workpieces located on the top surface of the picking member to be carried along the top surface and move together with the feeding structure. Only when several columnar workpieces encounter a groove during the movement will a predetermined number of columnar workpieces fall into the groove and be absorbed in the groove, and will not be carried by the disturbance wheel to continue moving on the top surface of the picking member.

[0026] The beneficial effects of this utility model include at least the following:

[0027] This utility model uses an integrated hopper and a linear motion module to achieve stable automatic feeding or receiving of materials. It employs upper and lower material receiving components with V-shaped slots / picking holes with precise settings of set intervals. The V-shaped slots are equipped with vacuum suction micropores or electromagnetic suction with preset polarity to adsorb and fix columnar workpieces by vacuum suction or electromagnetic means. The subsequent assembly action is simple, the overall stability of the equipment is good, the processing accuracy is greatly improved, the feeding rate is increased, and defects such as empty material, double material, and multiple material are effectively avoided.

[0043] Specifically, the first module 200 comprises a second driving member 203, the second driving member 203 drives the base 202 to rise or fall in the direction perpendicular to the bottom plate 201. After the main body of the workpiece 100 to be processed is positioned and clamped, it can be lifted (achieved by a rack, spline and the like) and rotated; subsequent processes such as bending, welding and glue dispensing are arranged according to actual needs. In an embodiment, the second driving member 203 is a motor, and can also be other suitable driving devices.

[0044] The hopper module 400 further comprises a third driving member 407 for driving the lever arm 406 to make lever movement around the rotation shaft 405, thereby driving the fork 403 to lift up or drop down. The fork 403 is provided with a U-shaped claw 404 at the end away from the lever arm 406, and the U-shaped opening in the middle of the claw 404 is aligned with the disturbing wheel 408, so that when the claw 404 is lifted up with the fork 403, the disturbing wheel 408 partially extends into the U-shaped opening to prevent the columnar workpiece 700 placed on the fork 403 from falling off the claw 404. In an embodiment, the third driving member 407 is a pneumatic cylinder, or other suitable driving device.

[0045] The third module 500 further comprises a vertical slide rail 503 and a vertical sliding frame 502 mounted on the support 501, a fifth driving member 504 for driving the vertical sliding frame 502 to move along the vertical slide rail 503, a rotating mechanism 505, and a sixth driving member 508. The fifth and sixth driving members 504 and 508 can be motors, or other suitable driving devices.

[0046] The taking member of the taking module 600 comprises a horizontally placed upper taking member 601 and a lower taking member 603. The top surface of the upper taking member 601 is provided with a plurality of V-shaped grooves 602 for accommodating the columnar workpieces 700, and the lower taking member 603 is provided with a plurality of taking holes 604 corresponding to the V-shaped grooves 602. The top end of each V-shaped groove 602 is only large enough to allow one columnar workpiece 700 to fall into it. The taking module 600 further comprises a vacuum suction component 607 provided at the end of the upper taking member 601, and the upper taking member 601 is provided with a vacuum suction structure in communication with the vacuum suction component 607. The inner wall of each V-shaped groove 602 is provided with a vacuum suction port in communication with the vacuum suction structure. In this embodiment, the grooves 602 are V-shaped; in other embodiments, the grooves 602 can be other shapes, which can be set according to actual conditions.

[0047] As shown in Figures 3-5 The hopper module 400 further comprises a fourth driving member 410 for driving the disturbing wheel 408 to rotate around its central shaft. As shown in Figures 7-10As shown, when the hopper module is in the working state with the upper taking material piece 601, the upper taking material piece 601 is located in the U-shaped opening in the middle of the pawl 404 and is opposite to the disturbing rotating wheel 408. The top surface of the upper taking material piece 601 with the V-shaped groove 602 is higher than the top surface of the pawl 404, and the gap between the top surface of the upper taking material piece 601 and the bottom wheel surface of the disturbing rotating wheel 408 in the vertical direction is less than the diameter of the columnar workpiece 700. When the columnar workpiece 700 moves along the upper taking material piece 601 in the horizontal direction under the driving of the horizontal sliding frame 304, the rotation of the disturbing rotating wheel 408 makes the columnar workpieces 700 on the top surface of the upper taking material piece 601 move along the moving direction of the hopper module 400 together with the hopper module 400. Only when the columnar workpieces 700 hit a V-shaped groove 602 during the movement, one columnar workpiece 700 will fall into the V-shaped groove 602 and be adsorbed in the V-shaped groove 602 without being taken along by the disturbing rotating wheel 408 to continue moving on the top surface of the upper taking material piece. The fourth driving piece 410 can be a motor or other suitable driving device.

[0048] Specifically, the disturbing rotating wheel 408 rotates clockwise during the whole movement of the hopper module 400 from right to left. The columnar workpiece 700 at the bottom layer is disturbed horizontally and parallelly, so that the columnar workpiece 700 is parallel to the slot of the V-shaped groove 602, thereby easily entering the groove and being more stable in the groove under the action of the vacuum suction or electromagnetic force. The columnar workpiece 700 that has entered the groove is not disturbed during the continuous rotation of the disturbing rotating wheel 408 and the continuous left movement of the hopper module 400, while the columnar workpieces 700 on the top surface of the upper taking material piece 601 are disturbed and retreated. The fourth driving piece (cylinder) 407 drives the lever arm 406 to make the fork 403 with the pawl 404 lift or drop through the lever action around the rotating shaft 405. During the discharging process, the top surface of the pawl 404 is lower than the top surface of the upper taking material piece 601 with the V-shaped groove 602. During the collecting process, the top surface of the pawl 404 is higher than the bottom (the lowest side) of the wheel surface of the disturbing rotating wheel 408. The disturbing rotating wheel 408 disturbs the columnar workpiece 700 to retreat so that it is not pressed by the disturbing rotating wheel 408.

[0049] The rotating mechanism 505 is connected between the upper material taking member 601 and the sixth driving member 508, and the rotating mechanism 505 comprises a shaft 506 connected to the upper material taking member 601, and the shaft 506 is connected to the driving shaft of the sixth driving member (motor) 508 through a shaft coupling 507. When the material bin module 400 is switched from the material discharging state to the material collecting state, the vertical sliding frame 502 of the third module 500 drives the upper material taking member 601 to move vertically downward along the vertical sliding rail 504 by a predetermined distance under the driving of the motor 504, and then the sixth driving member (motor) 508 drives the upper material taking member 601 to rotate outward by about 90 degrees towards the lower material taking member 603. That is, the sixth driving member 508 drives the rotating mechanism 505 to drive the upper material taking member 601 to rotate by 90 degrees around the shaft of the rotating mechanism 505, so that the surface of the upper material taking member 601 provided with the V-shaped groove 602 is perpendicular to the surface of the lower material taking member 603 provided with the material taking hole 604, so that the V-shaped groove 602 of the upper material taking member 601 is aligned with the corresponding material taking hole 604, and the columnar workpiece 700 accommodated in each V-shaped groove falls into the corresponding material taking hole 604. Each material taking hole 604 is provided with a guide groove with a large upper cross section and a small lower cross section.

[0050] In this process, the upper material taking member 601 turns over by about 90 degrees while keeping the columnar workpiece 700 in a vacuum suction state, and the vacuum breaking function of the electromagnetic valve is used to realize micro-positive-pressure blowing, which assists the columnar workpiece 700 to enter the guide groove of the material taking hole 604. The guide groove is provided with a large opening, which gradually decreases in the process of falling.

[0051] The material taking module 600 further comprises a plurality of material guide pipes 605 and sockets 606, each material guide pipe 605 is communicated to the corresponding material taking hole 604 at one end and is communicated to the corresponding insertion hole of the socket 606 at the other end, and the insertion holes of the sockets 606 are arranged corresponding to the insertion openings on the workpiece 100 to be processed, so that the columnar workpiece 700 falls freely from the material guide pipe 605, passes through the corresponding insertion hole and is inserted into the corresponding insertion opening. The columnar workpiece 700 continuously accelerates by using its own gravity, and then enters the material guide pipe 605 (copper condenser pipe is used in this embodiment, the inner wall of which is smooth and has no resistance, and is easy to bend), and finally guides the columnar workpiece 700 to the corresponding insertion hole of the socket connected to the bottom end of the material guide pipe 605. The material guide pipe 606 can have a certain flexibility, so that its shape can be appropriately adjusted according to actual needs, and the material thereof can be copper, alloy or plastic, etc.

[0052] Further, the lower part of the upper and lower material taking members can be provided with a fine-tuning stretching and ejecting screw to fine-tune the straightness of the upper surface of the material taking member, and to ensure the precision of material taking. After the upper material taking member 601 turns over, the micro-positive pressure of the vacuum electromagnetic valve can be used to realize blowing and discharging. Further, the utility model can use a speed regulating motor to realize simultaneous feeding of multiple material bins through synchronous belts and pulleys, that is, multiple material bin modules 400 can be installed together or separately for material taking (material discharging-material collecting).

[0053] As Figure 10 shown, the utility model also provides a loading structure, main include mounting plate 401, material fork 403 and disturbance runner 408. Mounting plate 401 is used to install loading structure on mobile component (that is Figure 1 Horizontal sliding frame in 304);The pivot 405 is arranged on material fork 403, and material fork 403 is connected to mounting plate 401 through pivot 405, one end of material fork 403 is connected with lever drive 407, the other end is connected with pawl 404;Disturbance runner 408 is connected to the position of mounting plate 401 corresponding pawl 403 through runner fixing part 409, and runner drive 410 is connected to disturbance runner 408. Among them, the opening is arranged in the middle of pawl 404, the opening is aligned with disturbance runner 408, so that when pawl 404 is lifted with material fork 403, part of disturbance runner 408 extends into the opening to prevent the columnar workpiece 700 placed on material fork 403 from falling off pawl 404. The shape of pawl 404 can be any suitable shape structure, and in an embodiment, it is a U-shaped structure with a U-shaped opening in the middle. Runner fixing part 409 includes first runner fixing part 4091 and second runner fixing part 4092, and first runner fixing part 4091 and second runner fixing part 4092 are sleeved on both ends of the central shaft of disturbance runner 408 through the respective corresponding shaft holes, so as to clamp disturbance runner 408 therebetween.

[0054] When the loading structure is in the working state with the material taking part 601, the material taking part 601 is located in the opening of the pawl 404 and is opposite to the disturbance runner 408, the top surface of the material taking part 601 provided with a plurality of grooves 602 is higher than the top surface of the pawl 404, and the gap between the top surface of the material taking part 601 and the bottom of the runner surface of the disturbance runner 408 in the vertical direction is a predetermined value, so that a predetermined number of columnar workpieces 700 can pass through the gap. When the loading structure moves along the material taking part 601 with the columnar workpieces 700 under the drive of the mobile component 304, the rotation of the disturbance runner 408 causes a plurality of columnar workpieces 700 located on the top surface of the material taking part 601 to move along the top surface with the loading structure, and only when a plurality of columnar workpieces 700 encounter a groove 602 during the movement, a predetermined number of columnar workpieces 700 will fall into the groove 602 and be adsorbed in the groove 602 without being taken along by the disturbance runner 408 to continue moving on the top surface of the material taking part. Further, a guide plate can be additionally provided inside the disturbance runner 408 and can be adjusted up and down to adjust the opening size at the inlet of the disturbance runner 408 and the pressure size generated by gravity and the inclined surface of the hopper, so as to realize more stable feeding and discharging.

[0055] The columnar workpiece 700 of the utility model can be a tubular piece, a material piece, etc., and in an embodiment, the columnar workpiece 700 can be a medical material.
