Description
Technical Field
[0001] This invention belongs to the technical field of electric fan assembly equipment, and particularly relates to a screw pack feeding device for an electric fan speed controller production line. Background Technology
[0002] In the production of electric fan speed controllers, to facilitate the smooth assembly of the speed controllers by users, the screws used for installation are typically packed in plastic bags to form screw bundles. These bundles are then manually or using a vibrating feeder to load the screw bundles into the lower housing of the speed controller. After the upper cover is closed, the bundles are boxed and packaged before being stored for shipment. It is obvious that manual feeding (of the screw bundles) is inefficient and is no longer used in general automated production lines. On the other hand, the accuracy of using a vibrating feeder is poor, sometimes pushing more than two screw bundles at a time. This not only increases production costs but also causes discrepancies between the packing list and the actual contents, seriously affecting the production quality and reputation of the company's products. Summary of the Invention
[0003] The purpose of this invention is to provide a screw bag feeding device for an electric fan speed controller production line with accurate feeding.
[0004] The objective of this invention is achieved as follows: A screw pack feeding device for an electric fan speed controller production line includes a workbench, a vibrating feeding disc on the workbench, and a speed controller conveyor belt that drives intermittent feeding. The discharge port of the vibrating feeding disc is connected to a screw pack temporary storage chamber with an upper opening. A screw pack guide slide is provided above the lower housing of the speed controller on the speed controller conveyor belt. A conveying mechanism using a vacuum suction cup is provided between the guide slide and the temporary storage chamber to move the screw pack from the temporary storage chamber to the top of the guide slide. The screw pack slides from the guide slide into the lower housing of the speed controller by gravity. The action of the conveying mechanism is controlled by a controller.
[0005] As a further optimization of the above technical solution, the conveying mechanism includes a column mounted on a workbench. A first slider, driven by a first cylinder, slides on a first slide rail arranged horizontally on the upper crossbeam of the column. A second slider, driven by a second cylinder, slides on a vertical second slide rail arranged below the first slider. A vacuum suction cup is arranged below the second slider. The horizontal movement of the first slider driven by the first cylinder and the vertical movement of the second slider and vacuum suction cup driven by the second cylinder can enable the vacuum suction cup to pick up the screw package from the temporary storage chamber and deliver it to the top of the guide slide for placement.
[0006] As a further optimization of the above technical solution, the vacuum suction cup is connected in sequence to a solenoid valve, a vacuum tank and a vacuum pump through a conduit. The controller controls the action of the first cylinder and the second cylinder according to the set program, and controls the vacuum suction cup to vacuum or non-vacuum feeding through the solenoid valve.
[0007] As a further optimization of the above technical solution, a first transverse slide rail is provided on one side of the crossbeam, and a first cylinder is installed on the other side through a protruding fixed seat. The end of the piston rod of the first cylinder is fixedly connected to a first slider that slides on the first slide rail. The action of the first cylinder drives the first slider to move on the first transverse slide rail.
[0008] As a further optimization of the above technical solution, a vertical second slide rail is provided on the lower side of the first slider, and a second cylinder is vertically installed on the upper side through a protruding fixed seat. The end of the piston rod of the second cylinder is fixedly connected to the second slider that slides on the second slide rail. The action of the second cylinder drives the second slider to move on the vertical second slide rail.
[0009] As a further optimization of the above technical solution, a feeding funnel for feeding material into the vibrating feeding plate is provided on one side or above the vibrating feeding plate.
[0010] As a further optimization of the above technical solution, the guide slide is an inclined slide plate provided on the upper part of the bracket set on the workbench, with side plates provided on both sides of the slide plate. The side plates and the slide plate form a groove on which the screw package slides. The lower opening of the groove faces the upper part of the lower housing of the speed controller, and the upper opening of the groove can receive the screw package transported by the vacuum suction cup. Alternatively, the guide slide is a funnel-shaped feeding channel provided on the upper part of the bracket set on the workbench. The lower opening of the feeding channel faces the upper part of the lower housing of the speed controller, and the upper opening of the feeding channel can receive the screw package transported by the vacuum suction cup.
[0011] As a further optimization of the above technical solution, the bracket is equipped with a sensor to detect whether the lower housing of the speed controller is in place. The sensor receives the sensing information and sends it to the controller, which then controls the movement of the conveying mechanism.
[0012] As a further optimization of the above technical solution, the structure of the first slide rail and the second slide rail is that the opposite side walls of the rectangular body are respectively provided with arc-shaped grooves along the length direction of the first slide rail or the second slide rail. The structure of the first slider and the second slider is that the bottom wall of the rectangular body is provided with a rectangular groove, and the opposite side walls of the rectangular groove are respectively provided with arc-shaped protrusions that match the arc-shaped grooves. The first slider or the second slider slides on the first slide rail or the second slide rail, and the arc-shaped protrusions match the arc-shaped grooves.
[0013] As a further optimization of the above technical solution, the speed regulator conveyor belt is fixed with positioning seats for positioning the speed regulator at intervals. The positioning seats are provided with two or more positioning posts and positioning holes. The vertical plate of the detection right-angle plate is fixed in the vertical groove on one side of the positioning seat, and the horizontal plate of the right-angle plate is set horizontally.
[0014] The advantages of this invention compared to the prior art are: 1. This invention uses a vacuum suction cup to vacuum-adsorb the screw bags sent to the temporary storage chamber by the vibrating feeding tray. Since the vacuum suction cup can only adsorb the upper surface of one plastic bag at a time, it can only feed one plastic bag at a time. This overcomes the defect of feeding more than two screw bags at a time in the prior art, improves the accuracy and scientific nature of feeding, and also improves the production quality of the enterprise's products and the enterprise's reputation.
[0015] 2. This invention utilizes a cooling system and a vacuum system controlled by two cylinders, two sliders, and a controller. Although the structure is simple and the production cost is low, its application in the automatic feeding of screw packs in the production line of electric fan speed controllers solves the technical problem of excessive screw pack feeding in the prior art, and has good economic and social benefits.
[0016] 3. This invention utilizes a traditional vibrating feeder to sequentially deliver the screw packs to a temporary storage chamber for storage, creating conditions for vacuum adsorption.
[0017] 4. This invention utilizes the high accuracy of vacuum adsorption for screw packs, the rapid transmission of cylinder drive, and high production efficiency, saving feeding time and increasing overall production efficiency. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figures 1-6 : A screw pack feeding device for an electric fan speed controller production line includes a workbench 10, a vibrating feeding disc 12 on the workbench 10, and a speed controller conveyor belt 51 driven by a power source for intermittent feeding. The discharge port of the vibrating feeding disc 12 is connected to a screw pack storage chamber 13 with an upper opening. A screw pack guide slide 40 is provided above the speed controller lower housing 50 on the speed controller conveyor belt 51. A conveying mechanism 20 using a vacuum suction cup 30 is provided between the guide slide 40 and the storage chamber 13 to move the screw pack from the storage chamber 13 to the guide slide 40. The screw pack slides from the guide slide 40 into the speed controller lower housing 50 by gravity. The action of the conveying mechanism 20 is controlled by a controller.
[0027] As a further optimization of the above technical solution, the conveying mechanism 20 includes a column 31 set on the workbench 10. A first slide rail 25 is horizontally arranged on the upper crossbeam 24 of the column 31, on which a first slider 27 is slidably moved horizontally by a first cylinder 22. A second slide rail 29 is vertically arranged below the first slider 27, on which a second slider 28 is slidably moved vertically by a second cylinder 26. A vacuum suction cup 30 is arranged below the second slider 28. The horizontal movement of the first slider 27 driven by the first cylinder 22 and the vertical movement of the second slider 28 and the vacuum suction cup 30 driven by the second cylinder 26 can enable the vacuum suction cup 30 to pick up the screw package from the temporary storage chamber 13 and send it to the top of the guide slide 40 for placement.
[0028] As a further optimization of the above technical solution, the vacuum suction cup 30 is connected in sequence to the solenoid valve 33, the vacuum tank and the vacuum pump through the conduit 32. The controller controls the action of the first cylinder 22 and the second cylinder 26 according to the set program, and controls the vacuum suction cup 30 to vacuum or non-vacuum feeding through the solenoid valve 33. Non-vacuum feeding means that after the conduit 32 between the vacuum suction cup 30 and the solenoid valve 33 is vented to the atmosphere through the solenoid valve 33, the vacuum state is lost and the suction force on the screw package is lost, and the material is fed.
[0029] As a further optimization of the above technical solution, a first transverse slide rail 25 is provided on one side of the crossbeam 24, and a first cylinder 22 is installed on the other side through a protruding fixed seat 23. The end of the piston rod 21 of the first cylinder 22 is fixedly connected to the first slider 27 sliding on the first slide rail 25. The action of the first cylinder 22 drives the first slider 27 to move on the first transverse slide rail 25.
[0030] As a further optimization of the above technical solution, a vertical second slide rail 29 is provided on the lower side of the first slider 27, and a second cylinder 26 is vertically installed on the upper side through a protruding fixed seat.

The action of the second cylinder 26 drives the second slider 28 to move on the vertical second slide rail 29.
[0031] As a further optimization of the above technical solution, a feeding funnel 11 for feeding material into the vibrating feeding plate 12 is provided on one side or above the vibrating feeding plate 12, and the outlet of the feeding funnel 11 is located above the vibrating feeding plate 12.
[0032] As a further optimization of the above technical solution, the guide slide 40 is provided with an inclined slide plate 41 on the upper part of the bracket 43 set on the worktable 10. Side plates 42 are respectively provided on both sides of the slide plate 41. The side plates 42 and the slide plate 41 form a slide groove on which the screw pack slides. The lower opening of the slide groove faces the upper part of the lower housing 50 of the speed controller, so as to facilitate the placement of the screw pack on the lower housing 50 of the speed controller. The upper opening of the slide groove can receive the screw pack transported by the vacuum suction cup 30 and send it through the inclined slide plate 41. The material can shorten the moving distance of the first slider 27, thereby shortening the feeding distance of the vacuum suction cup; or the guide slide 40 is a funnel-shaped feeding channel provided on the upper part of the bracket set on the worktable 10, with the lower opening of the feeding channel facing the upper part of the speed controller lower housing 50, so as to put the screw pack on the speed controller lower housing 50. The upper opening of the feeding channel can receive the screw pack transported by the vacuum suction cup 30. The funnel-shaped feeding channel has good safety, and the screw pack is not easy to be thrown out from one side of the funnel-shaped feeding channel.
[0033] As a further optimization of the above technical solution, the bracket is provided with a sensor 44 for detecting whether the lower housing 50 of the speed controller is in position. The sensor 44 receives the sensing information and sends it to the controller, which controls the movement of the conveying mechanism 20.
[0034] As a further optimization of the above technical solution, the first slide rail 25 and the second slide rail 29 are both provided with arc-shaped grooves 71 along the length direction of the first slide rail 25 or the second slide rail 29 on the opposite side walls 72 of the rectangular body 70. The first slider 27 and the second slider 28 are both provided with rectangular grooves 74 on the bottom wall of the rectangular body 73. Arc-shaped protrusions 75 matching the arc-shaped grooves 71 are provided on the opposite side walls 72 of the rectangular grooves 74. The first slider 27 or the second slider 28 slides on the first slide rail 25 or the second slide rail 29, and the arc-shaped protrusions 75 match the arc-shaped grooves 71. The structure is simple, easy to process, has a large load-bearing capacity, and good guidance.
[0035] As a further optimization of the above technical solution, the speed regulator conveyor belt 51 is fixed with positioning seats 60 for positioning the speed regulator at intervals. The positioning seats 60 are provided with two or more positioning posts 65 and positioning holes 64 for easy positioning. The vertical plate 63 of the detection right angle plate 61 is fixed in the vertical groove on one side of the positioning seat 60, and the horizontal plate 62 of the right angle plate 61 is set horizontally.
