Description

Technical Field

[0001] The invention relates to the technical field of light bulb production and design, and relates to an automatic PC lampshade installation device, in particular to a spherical PC lampshade, and more specifically to a milky white diffusion cover. Background Art

[0002] PC lampshades are made of PC (polycarbonate) as raw materials for light bulbs, LED lamps, LED fluorescent lamps, car lights and lamp housings. Most of the PC lampshades on the market use milky white diffusion covers. This non-completely transparent PC lampshade will not cause dazzling or glaring string light in the center of the light source, which meets human requirements for light. In addition, PC lampshades are light (density is lower than glass), not easy to break (less damage), and imported PC raw materials are used. They basically do not change color for 5-10 years, have a variety of colors, are anti-aging, and have strong weather resistance. They are very popular in the market, and the lamps produced are also very competitive.

[0003] PC lampshade, as the name implies, has an opening. They are usually stacked in one place after production, with some openings facing downward, some facing upward, and some facing all around. In the traditional lamp production method, the installation of PC lampshade requires manual flipping of the opening so that the PC lampshade with the opening downward can be used on the production line to install the PC lampshade on the lamp head (in actual production, the bulb is placed so that the lamp head is located below the PC lampshade, which is conducive to automatic installation of the PC lampshade). The existing production method does not have equipment to automatically flip the opening of the PC lampshade downward, resulting in low installation efficiency and low output. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problem of low production efficiency caused by manually turning down the opening of the PC lampshade during production. The technical solution adopted is:

[0005] An automatic PC lampshade loading device comprises a screening device, a feeding mechanism for feeding PC lampshades with disordered opening directions to the screening device, a feeding device for feeding PC lampshades with downward openings out of the screening device, and a kicking device for kicking out PC lampshades with no downward openings in the screening device;

[0006] The screening device comprises a rotatable screening turntable arranged on a frame, the outer edge of the screening turntable is provided with a plurality of notches for accommodating a PC lampshade, a pad with an inclined surface inclined inwardly is installed below the notch, and the PC lampshade slides or rolls on the inclined surface of the pad as the screening turntable rotates; the feeding mechanism comprises a hopper higher than the frame, a feed port is provided at the upper end of the side wall of the hopper close to the frame, the feed port is provided with an inclined inlet channel connected to the outer edge of the screening turntable, the bottom of the hopper is an inclined surface inclined toward the frame, and the bottom of the hopper is provided with a rising platform that can rise to the feed port; the kicking device is located in the middle section of the screening turntable, and comprises a nylon strip connected to the motor and the motor output shaft and a kicking port, and the nylon strip is located directly above the notch; the delivery device comprises a cylinder and a feeding track installed below the screening turntable, the piston rod of the cylinder faces the feeding track, and the feeding track is located at the end of the screening turntable.

[0007] Pour the batches of PC lampshades into the upper hopper. There is a lifting cylinder at the bottom of the upper hopper. The lifting cylinder sends about 4-8 PC lampshades to the screening turntable each time. The PC lampshades are forced to flip by the self-rotation in the screening turntable. When the PC lampshades flip to the opening facing downward, the PC lampshades will no longer flip, thus achieving the consistency of the direction of the PC lampshades. At the rear of the screening turntable, two unloading ports are opened, and the PC lampshades with the opening facing downward are pushed to the unloading track by the cylinder.

[0008] Furthermore, the notch is semicircular in shape, and the linear distance from the innermost side of the notch to the inclined surface of the backing plate is less than the height of the PC lampshade. The notch abuts against the PC lampshade, so that the PC lampshade is located in the middle of the inclined surface of the backing plate, which is convenient for kicking off the PC lampshade without opening downward.

[0009] Furthermore, the screening turntable is circular, and a plurality of notches are evenly arranged on the outer edge of the screening turntable. The PC lampshade moves in a circular path along with the rotation of the screening turntable.

[0010] Furthermore, the pad is in the shape of a ring, the inner ring is lower than the outer ring, and the cross section of the pad is a slope inclined inward. Since the pad is inclined inward, when the PC lampshade is turned over to open downward, it is ensured that the PC lampshade is buckled on the pad and is inclined, and is not easily kicked out by the nylon strip.

[0011] In order to prevent the PC lampshade from falling off the screening turntable, a surrounding edge is installed on the periphery of the screening turntable, and a baffle is provided on the screening turntable.

[0012] At the same time, in order to prevent the PC lampshade from falling into the center of the screening turntable, the surrounding edge is provided with a kick-out port at a position opposite to the feed port, and a discharge port is provided at a rear section of the PC lampshade's travel route.

[0013] Preferably, the delivery device comprises a cylinder installed on the screening turntable, the front end of the piston rod of the cylinder faces the unloading port, the unloading port is equipped with a unloading track, and the cylinder pushes the PC lampshade to the unloading track.

[0014] Preferably, the frame is equipped with a kicking device for kicking the PC lampshade with an upward opening off the screening turntable, the kicking device comprises a motor and a nylon strip connected to the motor, the nylon strip is located directly above the notch and directly above the kicking opening. An electric shock is installed at the rear half of the screening turntable to drive the nylon strip to flip outward from the center of the turntable, and the PC lampshade with no downward opening is removed from the screening turntable to prevent it from flowing into the subsequent process.

[0015] The inlet channel is arranged to be inclined, and is inclined from the feed port toward the screening turntable.

[0016] The top of the inlet channel is provided with an air nozzle. The top of the riser is an inclined surface, the riser is located on the left side of the hopper, the bottom of the hopper is an inclined surface inclined from the right side to the left side, and the inclined surface of the riser top is consistent with the inclined surface of the hopper bottom.

[0017] The PC lampshade falls into the gap from the feed port, and the PC lampshade with the opening downward is buckled on the pad, and slides on the pad to the delivery device as the screening turntable rotates; the PC lampshade with no opening downward, its arc surface is in contact with the pad, and rolls on the pad as the screening turntable rotates, rolls to the opening downward and slides on the pad to the delivery device as the screening turntable rotates; the PC lampshade with no opening downward, its arc surface is in contact with the pad, and rolls on the pad to the kicking device as the screening turntable rotates, and is brought out of the screening turntable by the rotating nylon strip.

[0018] Compared with the prior art, the present invention has the following beneficial effects: the device for automatically turning the opening of the PC lampshade downward is suitable for automated production and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following further describes the embodiments of the present invention in combination with the accompanying drawings and implementation methods. The positional relationship described in the text is consistent with the positional relationship direction of the accompanying drawings themselves, which is only for the convenience of description and does not limit the structure of the present invention.

[0027] In this embodiment, Figures 1 to 6 , including a hopper 1 and a frame 2, the hopper and the frame are arranged in a staggered manner, the hopper is higher than the frame, the left side of the hopper is close to the frame and is higher than the frame by a certain distance. A rising platform 3 is provided at the bottom of the left end of the inner side of the hopper, and the rising platform can rise to the top under the action of the jacking cylinder. A feeding port 4 is provided at the upper end of the hopper close to the frame, and the table top of the rising platform is inclined. The PC lampshade automatically slides into the feeding port under the action of the rising platform, and 4 to 8 PC lampshades can be fed each time.

[0028] The frame is provided with a screening device, which includes a rotating screening turntable 5, a surrounding edge 6 and a baffle plate 7 surrounding the screening turntable. The surrounding edge can prevent the PC lampshade from falling out of the frame. The surrounding edge is provided with a kick-out port 8 at a position opposite to the feed port, and a discharge port 9 is provided at a position of the rear section of the PC lampshade's travel route. The discharge port is equipped with a discharge track 10. A cylinder is provided below the screening turntable, and the piston rod of the cylinder faces the discharge port. The feed port is connected to the screening turntable through an inlet channel 11 with a downward inclination, and the PC lampshade automatically slides down at the feed port and falls into the screening turntable. The feed port is provided with an air nozzle 12 above. Accelerate the sliding speed of the PC lampshade. The baffle plate is installed on the screening turntable and relative to the feed port to prevent the 4-8 PC lampshades entering from the feed port from falling into the center of the screening turntable and being unable to flip.

[0029] The middle part of the screening turntable is provided with a kicking device at the kicking opening 8, which includes a motor 17 and a nylon strip 18 connected to the motor output shaft, and the nylon strip is located just above the notch. The motor drives the nylon strip to flip outward from the center of the screening turntable.

[0030] A delivery device is provided at the last section discharge port 9 of the screening turntable, comprising a cylinder installed below the screening turntable, the piston rod of the cylinder faces the discharge track, and the discharge track faces the notch.

[0031] In order to facilitate the understanding of the flipping of the PC lampshade in this embodiment, first of all, the PC lampshade is a hollow hemispherical shape with an opening, and then the movement principle is introduced: a hemispherical product, with its flat part buckled on a plane, is easy to slide but not easy to roll under a certain external force. However, if its arc surface is placed on a plane, it will roll under a very small external force until it buckles on the plane and stops moving.

[0032] The outer edge of the screening turntable is evenly provided with semicircular notches 13, which can accommodate a PC lampshade. The PC lampshade that falls into the screening turntable just enters the notch. A pad 14 is also provided below the notch. The pad 14 has an inwardly inclined surface (there is no pad 14 at the delivery device, that is, the surface below the screening turntable at the delivery device is a flat surface). The straight-line distance h1 from the innermost side of the notch to the pad inclined surface is less than the height h2 of the PC lampshade. The notch limits the PC lampshade to the middle section of the inclined surface. Figure 6 As shown. The opening direction of the PC lampshade that falls into the gap is uncertain, and the PC lampshade that is used in the next process needs to be opened downward. The PC lampshade has the following movements in the gap.

[0033] Case 1: When the opening is downward, it is buckled on the slope, and slides with the rotation of the screening turntable and under the push of the notch, and slides to the kick-out device section. Since it has always been buckled on the slope and is also tilted, it is not easy for the flipped plastic nylon strip to push it to the top of the slope and overcome the sliding friction to bring it out of the slope. (A hemispherical object is buckled on the slope. Without the action of external force, it is at the bottom of the slope. Only with the push of a larger external force can it be pushed to the top of the slope, or even off the slope.) The PC lampshade continues to slide and slides to the delivery device section. The cylinder 15 pushes the piston rod 16 to send the screening turntable to the unloading track and enter the next production process.

[0034] Case 2: When the opening is not facing downward, its arc surface contacts the inclined plane, and it rolls along with the self-rotation of the screening turntable and under the push of the notch, it rolls for a distance and opens and flips downward before the kick-off device section. The movement of the rear part is the same as that of Case 1, and it is finally sent out by the sending device.

[0035] Case 3: When the opening is not downward, its arc surface contacts the inclined plane, and it rolls with the rotation of the screening turntable and under the push of the notch. After rolling for a distance, it has not turned over and opened downward. When it passes through the kick-out device section, it rolls out of the inclined plane to the kick-out port 8 under the action of the external force of the nylon strip. The PC lampshade with the opening upward is more likely to be taken out of the inclined plane (when the PC lampshade with the opening upward passes the flipping nylon strip, the nylon strip will enter the opening, the nylon strip will press against the edge of the PC lampshade, and then it will be immediately taken out of the kick-out port by the flipping nylon strip). These PC lampshades can be recycled into the hopper.

[0036] The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
