Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a bulb focusing welding device. Background Technology

[0002] A light bulb is a lighting device that emits light through electrical energy. Its principle is based on the thermal effect of electric current, which converts electrical energy into internal energy and light energy. A typical structure includes a filament, a lamp holder, a lamp base, and a glass shell. During the production process, the lamp holder, the cap, and the adjustment ring need to be welded together as a whole.

[0003] During the welding process on the production line, adjusting rings are typically fed using a vibratory feeder. This feeding process involves conveying the rings through a straight conveyor section, allowing a robotic arm or other mechanical device to grip and transfer them to the next process. However, this method lacks a barrier between adjacent adjusting rings, making it easy for the ring to scrape against the next one when picking it up, potentially causing scratches or the ring to fall off. Furthermore, there is a lack of effective vertical restraint on the adjusting rings, relying solely on multiple guide rails. While there is a certain gap between the guide rails and the adjusting rings to allow passage, this gap can affect the posture of the next adjusting ring when it is picked up later. Summary of the Invention

[0004] The purpose of this invention is to provide a bulb focusing welding device that solves the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A bulb focusing welding device includes a frame, on which a vibratory feeder and an output track connected to the output port of the vibratory feeder are arranged. A conveyor belt is arranged on the output track. A reciprocating rotation mechanism connected to the frame is arranged on one side of the output track. Multiple isolation components for isolating two adjacent workpieces are arranged at equal intervals on the reciprocating rotation mechanism. The isolation assembly includes a base fixed on a reciprocating rotation mechanism and a partition rotatably connected to the base. The partition moves cyclically with the reciprocating rotation mechanism and intervenes in the gap between adjacent workpieces in the workpiece conveying path to form a physical barrier. When the partition moves to the end of the conveying process, it tilts and rotates to an avoidance posture with the assistance of magnetic attraction. After leaving the end of the conveying process, it returns to the isolation posture by its own gravity.

[0006] As a preferred embodiment of the present invention, the frame is provided with a roller pressing assembly for rolling contact with the top of the workpiece. The roller pressing assembly includes a plurality of pressure rollers arranged along the conveying direction. The contact areas of adjacent pressure rollers are transitioned and connected by staggered annular grooves to form a continuous and gapless rolling pressing on the top of the workpiece.

[0007] As a preferred embodiment of the present invention, the reciprocating rotation mechanism includes a plurality of sprockets mounted on a frame and a chain sleeved on the plurality of sprockets, wherein one of the sprockets is connected to a drive device.

[0008] As a preferred embodiment of the present invention, the base of the isolation component is fixedly mounted on the chain, and a right-angle groove is provided on the base. A partition is rotatably connected in the right-angle groove, and when the partition moves to the end of the conveyor belt, it tilts and rotates under its own gravity. An obstacle passage is provided on the output track for the partition to pass through.

[0009] In a preferred embodiment of the present invention, both the partition and the inner wall of the right-angle groove are magnetic. The partition is magnetically attracted to the inner wall of the right-angle groove and rotates under its own gravity.

[0010] As a preferred embodiment of the present invention, a magnetic block is provided on the frame and the magnetic block is located at the conveying end of the conveyor belt. A magnetic plate and a limiting protrusion are rotatably connected to the partition. When the partition rotates to contact the inner wall on the other side of the right-angle groove, the distance between the magnetic block and the partition is greater than zero, and the magnetic plate abuts against the limiting protrusion.

[0011] In a preferred embodiment of the present invention, a baffle is provided on the partition, and the magnetic suction plate is located between the baffle and the limiting protrusion. When the magnetic suction plate is in contact with the baffle, the partition is parallel to the magnetic suction plate.

[0012] As a preferred embodiment of the present invention, the roller pressing assembly further includes a bracket mounted on a frame, on which multiple pressure rollers are rotatably connected at equal intervals along the conveying direction of the conveyor belt. Each pressure roller has multiple annular grooves, and a portion of one pressure roller located between two adjacent annular grooves is inserted into an annular groove on an adjacent pressure roller.

[0013] In a preferred embodiment of the present invention, a movable ring is rotatably connected within the annular groove, and the movable ring is in contact with the adjacent pressure roller.

[0014] Compared with the prior art, the present invention has the following advantages: This invention uses a vibratory feeder to transport the adjusting ring onto a conveyor belt, and a roller pressing assembly to restrict the up-and-down movement of the adjusting ring while ensuring normal transport of the adjusting ring and preventing the adjusting ring from deflecting during transport. Furthermore, an isolation assembly separates two adjacent adjusting rings to prevent damage to the next adjusting ring when it is picked up. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 6 As shown, the present invention provides a bulb focusing welding device, including a frame 1, a vibratory feeder 2 and an output track 3 connected to the output port of the vibratory feeder 2 are provided on the frame 1, a conveyor belt 4 is provided on the output track 3, a reciprocating rotation mechanism 5 connected to the frame 1 is provided on one side of the output track 3, a plurality of isolation components 6 for isolating two adjacent workpieces are provided at equal intervals on the reciprocating rotation mechanism 5, and the isolation components 6 can automatically rotate and reset under the action of gravity, and a roller pressing component 7 for rolling contact with the top of the workpiece is provided on the frame 1.

[0021] The reciprocating rotation mechanism 5 includes multiple sprockets 501 mounted on the frame 1 and chains 502 sleeved on the multiple sprockets 501, one of which is connected to a drive device.

[0022] The isolation component 6 includes a base 601 fixedly mounted on the chain 502. A right-angle groove 602 is provided on the base 601. A partition 603 is rotatably connected in the right-angle groove 602. When the partition 603 moves to the end of the conveyor belt 4, it tilts and rotates under its own gravity. An obstacle passage 607 is provided on the output track 3 for the partition 603 to pass through.

[0023] In use, the batch of disordered adjustment rings are placed in the vibratory feeder 2, and the vibratory feeder 2 transports the adjustment rings in an orderly manner to the conveyor belt 4 on the output track 3. After being transported to the end position by the conveyor belt 4, the adjustment plate is transferred to the next process (such as welding after connecting with the lamp head and the cap) by a robot or other clamping device for further processing.

[0024] During the conveying process on the conveyor belt 4, the roller pressing assembly 7 abuts against the top of multiple adjusting rings. The roller pressing assembly 7 rolls against the top of the adjusting rings, so that the adjusting rings are compressed vertically during the conveying process of the conveyor belt 4, and there is no gap in movement. This avoids the problem that the previous adjusting ring scrapes against the next adjusting ring when it is picked up, which would cause the posture of the next adjusting ring to deflect. This ensures that multiple adjusting rings can be picked up in sequence and in an orderly manner, and the rolling contact does not affect the normal conveying of the adjusting rings and will not hinder the movement of the adjusting rings.

[0025] Secondly, during the conveying of the adjusting rings, the isolation component 6 is driven by the drive device to rotate the sprocket 501, thereby driving the chain 502 to rotate cyclically, so that multiple isolation components 6 are cyclically inserted between two adjacent adjusting rings. Specifically, when the previous adjusting ring is conveyed to the conveyor belt 4 by the vibrating plate 2, the drive device drives the base 601 to move the corresponding partition 603 between the adjusting rings. This operation is repeated cyclically, so that there is a partition 603 between two adjacent adjusting rings, so as to avoid scraping the next adjusting ring when the previous adjusting ring is taken out.

[0026] After the previous adjusting ring is taken, the drive device drives the partition 603 to move to the end of the conveyor belt 4 and begins to turn downward. Then, under the action of gravity, the partition 603 rotates to abut against the other inner wall of the right-angle groove 602, avoiding interference of the partition 603 with the taking of the adjusting ring. As the chain 502 continues to rotate, the partition 603 moves cyclically to the input end of the conveyor belt 4 and turns upward. At this time, the partition 603 flips and resets under the action of gravity to cyclically isolate the adjusting ring.

[0027] The isolation component 6 and the roller pressing component 7 ensure that the position and orientation of the next adjusting ring are not affected when the adjusting ring is picked up, and avoid the problem of scratching and damaging the next adjusting ring.

[0028] In this embodiment, the conveyor belt 4, the drive device, and the vibratory feeder 2 are all existing technologies. For example, the drive device can be a motor or a combination of a motor and a reducer, the conveyor belt 4 can be a belt conveyor, and the vibratory feeder 2 is an auxiliary feeding device for automatic assembly or processing machinery. It arranges disordered workpieces in an orderly manner and transports them to the next process through vibration. It is usually composed of a hopper, a chassis, a controller, a linear feeder, a storage bin, and a photoelectric sensing system. It is a common feeding device. The technical principles of the three are not elaborated here.

[0029] Furthermore, when the partition 603, which moves to the end of the conveyor belt 4, rotates to abut against the inner wall of the right-angle groove 602, the inner wall of the right-angle groove 602 in contact with the partition 603 is in an inclined state, that is, the included angle between the two adjacent inner walls of the right-angle groove 602 is less than 90 degrees, so that the partition 603 can be smoothly reset under the action of gravity when it is flipped and reset, avoiding the problem of jamming.

[0030] Both the inner walls of the partition 603 and the right-angle groove 602 are magnetic. The partition 603 is magnetically attracted to the inner wall of the right-angle groove 602 and rotates under its own gravity.

[0031] Magnetic adsorption prevents the partition 603 from shaking randomly during movement. Especially after the adjusting ring is removed, the partition 603 rotates to contact the inner wall of the right-angle groove 602, and magnetic adsorption restricts the partition 603 from shaking randomly.

[0032] A magnetic block 604 is provided on the frame 1 and is located at the end of the conveyor belt 4. A magnetic plate 605 and a limiting protrusion 606 are rotatably connected on the partition 603. When the partition 603 rotates to contact the inner wall on the other side of the right angle groove 602, the distance between the magnetic block 604 and the partition 603 is greater than zero, and the magnetic plate 605 abuts against the limiting protrusion 606.

[0033] When the partition 603 moves to the end of the conveyor belt 4, the magnetic block 604 magnetically attracts the magnetic plate 605, causing the magnetic plate 605 to rotate and abut against the limiting protrusion 606. Under the action of the magnetic force, the partition 603 is driven to rotate, so as to assist the partition 603 to rotate quickly and abut against the inner wall of the right angle groove 602.

[0034] By setting the limiting protrusion 606, the magnetic suction plate 605 is prevented from abutting against the magnetic suction block 604. The magnetic suction plate 605 is rotatably connected to the partition plate 603, so that when the partition plate 603 abuts against the inner wall of the right angle groove 602, the magnetic suction plate 605 can also rotate to avoid interference with the inner wall of the right angle groove 602.

[0035] A baffle 608 is provided on the partition 603, and a magnetic plate 605 is located between the baffle 608 and the limiting protrusion 606. When the magnetic plate 605 is in contact with the baffle 608, the partition 603 is parallel to the magnetic plate 605.

[0036] The rotation range of the magnetic suction plate 605 is limited by the baffle 608 and the limiting protrusion 606 to prevent the magnetic suction plate 605 from rotating arbitrarily and interfering with other structures in the device, such as the frame 1, thus ensuring the normal operation of the entire device.

[0037] The roller pressing assembly 7 includes a bracket 701 mounted on the frame 1. Multiple pressure rollers 702 are rotatably connected to the bracket 701 at equal intervals along the conveying direction of the conveyor belt 4. Each pressure roller 702 has multiple annular grooves 703, and the multiple annular grooves 703 on two adjacent pressure rollers 702 are staggered. The portion of one pressure roller 702 located between two adjacent annular grooves 703 is inserted into the annular groove 703 on the adjacent pressure roller 702.

[0038] A movable ring 704 is rotatably connected inside the annular groove 703, and the movable ring 704 is in contact with the adjacent pressure roller 702.

[0039] By having the pressure roller 702 contact the top of the adjusting ring, the adjusting ring continues to roll and contact the pressure roller 702 during the conveying process of the conveyor belt 4, ensuring the normal conveying of the adjusting ring and avoiding the impact of the adjusting ring and the pressure roller 702 having a gap between them, which would affect the subsequent handling.

[0040] Secondly, the pressure roller 702 between two adjacent annular grooves 703 is inserted into the annular groove 703 on the adjacent pressure roller 702, thereby reducing the distance between the two adjacent pressure rollers 702 so that the adjusting ring continues to contact the pressure roller 702.

[0041] By setting the movable ring 704, two adjacent pressure rollers 702 can contact each other, and the problem of interference caused by different rotation directions when two adjacent pressure rollers 702 contact each other is avoided. The adjacent pressure rollers 702 contact with the movable ring 704 and rotate, but do not interfere with the rotation of the adjacent pressure rollers 702, further reducing the distance between the two adjacent pressure rollers 702.
