All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Referring to fig. 1 to 10, the present application provides a lamp cap gluing device, a housing of a lamp cap 600 is a columnar structure, an end cover 611 is provided at the other end, and a lamp pin 612 is installed on the end cover 611.

The lamp cap gluing device comprises a workpiece feeder 100, a conveyor 400, an alignment hook 410, a workbench 800, a transverse moving mechanism 700 and a gluing machine 900.

The workpiece feeder 100 has an outfeed side 110 and delivers the lamphead 600 through the outfeed side 110. Along the lamp head conveying direction (refer to the direction indicated by the arrow Y in fig. 1), one end of the conveyor 400 is a starting end 430 abutting against the discharging side 110, and the other end is a blanking end 421. The aligning hook 410 is swingably attached near the blanking end 421 for adjusting the orientation of the base 600.

The work table 800 includes a platen 841, the platen 841 has a receiving end 842 and a positioning end 843 opposite to each other, and a lamphead transfer direction (refer to a direction indicated by an arrow X in fig. 4) is from the receiving end 842 to the positioning end 843, where the lamphead transfer and the lamphead conveying are two-segment butt-jointed lamphead conveying process, and the lamphead transfer direction X and the lamphead conveying direction Y may be the same or different. The receiving end 842 is used for receiving the lamp head 600 falling from the blanking end 421, the bedplate 841 is provided with a slot 844 extending from the receiving end 842 to the positioning end 843, the slot 844 is used for accommodating the lamp pin 612, and the width of the slot 844 is gradually reduced along the lamp head transfer direction to position the lamp head 600. The traversing mechanism 700 drives the light head 600 to move from the receiving end 842 to the positioning end 843. The glue applicator 900 is provided with a liftable glue discharging head 910, and the glue discharging head 910 is used for applying glue to the lamp holder 600 at the positioning end 843 in a descending state.

The workpiece feeder 100, the conveyor 400, the alignment hooks 410, the traversing mechanism 700, and the glue applicator 900 of the present embodiment may each be of the prior art.

The workpiece feeder 100 may employ a vibratory pan, a rotary hopper, or the like. The stacked caps 600 are separately fed one by one to the conveyor 400 by the work feeder 100. The lightheads delivered via the conveyor 400 may have two orientations, a first orientation as shown in fig. 3 with the light feet 612 facing in the conveying direction and a second light foot 612 facing away from the conveying direction, not shown. The lighthead 600, after being transported to the blanking end 421, will fall downward under the influence of gravity. The alignment of the hooks 410 serves to turn the second orientation of the light head during the falling of the light head 600. The principle can be referred to in the prior art and will only be briefly described below. For the first orientation of the light head 600, the end cap 611 pushes the array of hooks 410 apart, and the array of hooks 410 does not function to flip the light head 600. With the cap 600 of the second orientation, the tips of the aligned hooks 410 extend into the opening of the cap 600, and the cap 600 is dropped with the opening facing upward by temporarily maintaining the height of one end of the opening. In one embodiment, the pivot axis of the alignment hook 410 is located above the blanking end 421, and the hook tip of the alignment hook 410 naturally hangs down to interfere with the lamp head conveying path on the conveyor 400.

The slot 844 provides clearance for the lamp base 612 to allow the end cap 611 to rest on the platen 841 when the lamp head 600 is dropped from the blanking end 421 to the receiving end 842 of the platen 841.

It should be noted that, the lamp cap 600 processed in the present embodiment includes, but is not limited to, the shapes in the drawings, for example, the number of the lamp pins 612 and the position on the end cover 611 can be adjusted appropriately according to the application, and thus the size, the number, and the like of the slots 844 can also be adjusted appropriately according to the size and the shape of the lamp cap to be processed, and these adjustments generally do not need to be creative work, and still fall within the protection scope of the present application. The collapsing of the slits 844 does not strictly limit the shape of the slits 844 to narrow in width at any microscopic section, and generally requires only a generally macroscopic tendency to collapse without jamming.

On the workbench 800, the lamp head 600 is transferred towards the positioning end 843 in a standing posture with an upward opening, and the traversing mechanism 700 provides power for the lamp head transfer, and various implementation manners exist in the prior art, for example, the lamp head 600 can be slowly pushed by directly utilizing a piston rod of an air cylinder. During the traverse of the base, a lateral holding force is applied to at least two lamp pins 612 by the platens 841 on both sides in the width direction of the slit 844, and the two lamp pins 612 in the slit 844 are gradually closed as viewed in the base transfer direction. When the lamp base 600 reaches the positioning end 843, the rotation angles of the lamp bases 600 along the circumferential direction of the lamp bases are basically the same, and therefore the lamp bases 600 are positioned.

After the lamp head 600 is positioned, the glue discharging head 910 descends and extends into the lamp head 600 through the opening of the lamp head 600. In an embodiment, the inner hole of the lamp head 600 is provided with a step matched with the lamp tube, and the glue outlet 910 sprays glue solution on the surface of the step, so that the lamp head 600 is conveniently butted with the lamp tube in a subsequent process. It should be noted that, in the whole production process of the lamp, the gluing is only one of the rings, and the subsequent processes such as marking, security fuse, detection and the like are also provided. The automatic positioning of the lamp holder is completed while the glue is applied, so that a special positioning mechanism is not required to be arranged on the subsequent equipment. In addition, the glue discharging head 910 may be fixed in the circumferential direction of the lamp head, or may be configured to be rotatable, depending on the requirement.

The lamp holder gluing device of the embodiment can automatically complete the feeding and gluing of the lamp holder 600, and facilitates the subsequent lamp processing procedures.

When the workpiece is spirally lifted in the conventional vibration disk, the lamp head 600 is integrally conveyed forward in an axially sliding manner, and the circumferential surface of the lamp head may be damaged by each vibration and contact with the support surface. In order to minimize the influence of abrasion on the appearance of the product, in one embodiment, the lamp cap gluing device comprises a hopper 1, a feeding assembly 2 and a driving mechanism 3.

The hopper 1 is used for storing lamp holders, and one side of the hopper 1 in the horizontal direction is a discharging side. The feeding assembly 2 comprises a fixed vertical wall 21 and a movable vertical wall 22, the fixed vertical wall 21 is positioned at the discharging side of the hopper 1, the movable vertical wall 22 is arranged in the hopper 1 in a lifting way and is attached to the fixed vertical wall 21, the top surface of the movable vertical wall 22 is a first slope surface 221, the movable vertical wall has a lifting limit state and a descending limit state, and in the lifting limit state, the first slope surface 221 is at least partially higher than the top surface of the fixed vertical wall 21 so as to guide the lamp caps to move out of the hopper through the top surface of the fixed vertical wall 21. The driving mechanism 3 drives the movable vertical wall 22 to ascend and descend.

The hopper 1 of this embodiment generally has an upwardly facing opening, side walls and a bottom wall. The shapes of the fixed standing wall 21 and the movable standing wall 22 are not limited, and may be a plate-like structure, a columnar structure, or the like. The inclination angles of the fixed vertical wall 21 and the movable vertical wall 22 are not limited, and may be perpendicular to the horizontal ground or have a certain inclination angle with respect to the horizontal plane. The fixed vertical wall 21 and the movable vertical wall 22 may be tightly attached, or an appropriate gap may be left as long as the gap does not block the lamp cap. The shape of the first slope surface 221 is not limited, and may be a plane, an arc surface or a surface allowing a certain fluctuation, as long as the lamp head can roll from the top of the slope to the bottom of the slope under the action of gravity.

In operation, the movable vertical wall 22 reciprocates on a lifting path, which may be perpendicular to the ground or at a certain inclination angle with respect to the ground, and the rising limit state is a state in which the movable vertical wall 22 is raised to the highest position, and the falling limit state is a state in which the movable vertical wall 22 is lowered to the lowest position. In the extreme downward state, part of the burners in the hopper 1 fall on the first slope 221. Then the movable vertical wall 22 starts to rise, and in the rising process, the first slope 221 on the top surface of the movable vertical wall 22 and the side surface of the fixed vertical wall 21 are respectively used as limiting structures on two sides of the lamp holder, so that the lamp holder is prevented from falling in the rising process. In the extreme ascending state, the movable vertical wall 22 has a certain staying time, which allows the lamp head to roll down from the first slope 221 to the fixed vertical wall 21, the rolling process of the lamp head can be an absolute smooth transition, and the lamp head is also allowed to be in an instantaneous suspended state due to a certain steep slope or fall, etc., which causes the lamp head to be separated from the supporting surface. After falling to the stationary vertical wall 21, the burner continues to roll forward by inertia onto the conveyor 400.

In the embodiment, different matching states between the fixed vertical wall 21 and the movable vertical wall 22 are utilized, in the ascending process, the fixed vertical wall 21 and the movable vertical wall 22 are matched into two-side limiting structures similar to the existing sliding grooves, and in the ascending limit state, the fixed vertical wall 21 and the movable vertical wall 22 are matched into a limiting structure with only one side, so that the lamp holder rolls outwards under the action of gravity. The motion mode in the whole feeding process is mainly lifting motion and rolling, and compared with the traditional sliding forward mode, the lamp holder has the advantages that the abrasion of the surface of the lamp holder is effectively reduced, and the appearance of a lamp product is favorably improved.

Specifically, in an embodiment, the first slope surface 221 is an arc surface, and a cross-sectional shape of the arc surface may be an arc shape, a wave shape, or the like. In another embodiment, the first slope surface 221 is a plane inclined by an angle less than 30 °, for example, an angle of 5 °, 10 °, 20 °. The first slope 221 has a high side on the side away from the fixed standing wall 21 and a low side opposite to the side close to the fixed standing wall 21.

When the first slope surface 221 is selected as a plane, the screening accuracy of the lamp holders in different postures can be improved by reasonably setting the friction coefficient of the first slope surface 221 and the stay time of the movable vertical wall 22 in the ascending limit state. In the following, the lamphead is assumed to be a standard cylinder, and the principle is explained by way of example in order to understand the screening process of the actual lamphead.

The light heads of the hopper 1 are randomly stacked in different postures, and in the ascending limit state, the light heads left on the first slope surface 221 have two postures, namely a lying posture and a standing posture. In the extreme raised state, there is rolling friction between the lying light head and the first ramp 221, which can roll onto the fixed standing wall 21 at a relatively fast speed during the dwell time. The lamp head which stands still has sliding friction with the first slope surface 221, and the movable vertical wall 22 starts to do descending movement before the lamp head slides to the fixed vertical wall 21, so that the lamp head which stands falls back into the hopper 1. Therefore, screening is performed by using the movement speed difference of the lamp heads in different postures on the first slope surface 221, and the screening accuracy is improved.

Referring to fig. 10, the fixed vertical wall 21 doubles as a side wall of the hopper 1 in order to facilitate the transfer of the caps onto the conveyor 400; the top surface of the fixed standing wall 21 is a second slope surface 211, and of the second slope surface 211, the side close to the movable standing wall 22 is a high side, and the side far from the movable standing wall 22 is an opposite low side. After the lamp cap rolls down on the fixed vertical wall 21, the lamp cap continues to roll outwards along the second slope 211, so that the lamp cap automatically falls onto the conveyor 400, and subsequent positioning and gluing are facilitated. The broken line P in fig. 10 illustrates the slip-off path of the burner.

In order to further reduce the surface wear caused by the collision, in an embodiment, in the extreme ascending state of the movable vertical wall 22, the bottom edge of the first slope surface 221 is at the same height as the top edge of the second slope surface 211.

Specifically, the lamp holder is of a columnar structure, the outer diameter of the lamp holder is D, the thickness of the movable vertical wall 22 is T1, the thickness of the fixed vertical wall is T2, 0.5D-T1-0.75D, and 0.5D-T2-0.75D.

When the circumference of the base is a standard circle, D indicates the diameter of the circle. When the circumferential surface of the base is non-circular, such as elliptical, D is the maximum radial dimension of the base. The lamp cap feeding process has movement in the vertical direction and movement in the horizontal direction, wherein the movement in the horizontal direction is directed to the discharging side from the center of the hopper 1. The thickness direction of the fixed vertical wall 21 and the movable vertical wall 22 refers to the horizontal direction toward the discharging side, and when the thicknesses of the fixed vertical wall 21 and the movable vertical wall 22 in the height direction are not equal, the thickness of the fixed vertical wall 21 can be understood as the horizontal projection length of the second slope surface 211 in the thickness direction, and the thickness of the movable vertical wall 22 can be understood as the horizontal projection length of the first slope surface 221 in the thickness direction. For the movable standing wall 22, the setting of T1 ensures: the first slope 221 in the thickness direction can accommodate only one lamp cap. Of course, in the axial direction, the first slope surface 221 may allow a plurality of lamp caps to be arranged in the axial direction, and simultaneously be loaded, so as to improve the efficiency. For the principle of T2 setting, reference may be made to T1, and therefore, the description is omitted. Generally, as long as one of T1 and T2 meets the setting, the lamp holders can arrive at the processing stations one by one.

In order to further improve the accuracy of screening, in an embodiment, a plurality of sets of feeding assemblies 2 are arranged, each fixed vertical wall 21 in the plurality of sets of feeding assemblies 2 forms a step structure side by side, and each second slope surface 211 is respectively used as a step surface with each level of sequentially increased height along the moving-out direction of the lamp cap; for the first slope surface 221 which ascends and descends between two adjacent steps, the first slope surface is connected with the step surface of the lower step in the descending limit state and connected with the step surface of the higher step in the ascending limit state, and therefore the lamp cap is transferred along the ascending direction of the steps.

The fixed vertical wall 21, the movable vertical wall 22, the first slope surface 221, and the second slope surface 211 in this embodiment generally refer to corresponding structures in each feeding assembly 2, and do not refer to a specific feeding assembly 2. When first domatic 221 links up with the step face of lower one-level, the top edge of first domatic 221 can be less than the bottom edge of the domatic 211 of second, can be along the parallel and level with the bottom edge of the domatic 211 of second, under the condition that does not cause serious to collide with, also allows the bottom edge that is a bit higher than the domatic 211 of second.

The lamp holder in the embodiment is not loaded by one lifting of one loading assembly 2, but loaded by relay transmission of a plurality of loading assemblies 2, and it can be understood that, in terms of time, the lamp holder is respectively transmitted to the first movable vertical wall, the first fixed vertical wall, the second movable vertical wall, the second fixed vertical wall, the third movable vertical wall and the third fixed vertical wall, and so on, and is transmitted upwards. Each material loading subassembly 2 can both realize one side screening, and the error is littleer after screening many times like this.

Referring to fig. 9, the bottom wall of the hopper 1 is provided with an escape opening through which the movable vertical wall 22 goes up and down, and the driving mechanism 3 includes a cylinder 31 and a lifting bottom plate 32. The cylinder 31 is located below the hopper 1. The lifting bottom plate 32 is fixed to a piston rod of the cylinder 31, and all the movable vertical walls 22 are fixed to the lifting bottom plate. In the embodiment, the relay transmission of the lamp holder between the feeding assemblies 2 is realized only by one air cylinder 31, so that equipment is saved.

Specifically, the conveyor 400 includes a conveyor belt 4 and two limiting members 5, the two limiting members 5 are respectively located on two sides of the conveyor belt 4 in the width direction, and a lamp cap conveying channel is located between the two limiting members 5. The outer diameter of the lamp holder is D, the length of the lamp holder is H, the width of the lamp holder conveying channel is S, and D < S < H is met.

The lamp holder is of a columnar structure, the outer diameter of the lamp holder is D, the length of the lamp holder is H, the width of the lamp holder conveying channel is S, and D < S < H is met. One of the fixed vertical walls 21 also serves as a limiting member, the limiting member 5 serves as another limiting member, the two limiting members 5 clamp the lamp head with a length direction in the middle, and the axial direction of the lamp head is approximately consistent with the conveying direction in the conveying process of the conveyor belt 4.

In one embodiment, the bottom wall of the hopper 1 has a third slope 11, the height of the third slope 11 gradually decreases along the moving direction of the lamp head, and the third slope is connected to the upstream-most movable vertical wall of the feeding assembly 2 at the lowest position, and the downstream-most fixed vertical wall 21 of the feeding assembly 2 also serves as one of the position-limiting members 5.

The upstream and downstream in this embodiment are in terms of the path of movement of the lighthead, and as a whole, the lighthead moves from upstream to downstream. Through setting up the domatic 11 of third, be favorable to the automatic upper reaches of dropping to material loading subassembly 2 of remaining lamp holder in the hopper 1, improve degree of automation.

The lamp cap gluing device further comprises a first photoelectric sensor 120, and the first photoelectric sensor 120 is used for detecting the number of the lamp caps in the lamp cap conveying channel and sending a control signal to the driving mechanism. Taking the driving mechanism as an air cylinder as an example, when the first photoelectric sensor 120 detects that the number of the lamp caps between the two limiting members 5 is zero, it indicates that the conveyor belt 4 has sent the lamp caps away, and when the air cylinder receives a descending signal, each movable vertical wall 22 moves downward to start feeding of the next batch of lamp caps.

The lamp cap gluing device further comprises a funnel 810 positioned between the blanking end 421 and the receiving end 842, wherein an inlet of the funnel 810 faces upwards to be butted with the blanking end 421, and an outlet of the funnel 810 faces downwards to be butted with the receiving end 842. The funnel 810 has an entrance aperture that is larger than an exit aperture, and the funnel 810 ensures that the lighthead 600 falls onto the platen 841 in a more standard upright position. Specifically, the funnel 810 comprises a conical section 811 and a constant diameter section 812 which are sequentially butted from top to bottom, the caliber of the conical section 811 is gradually reduced, and the caliber of the constant diameter section 812 is consistent with the outer diameter of the lamp head 600.

In an embodiment, there is a gap between the blanking end 421 and the funnel 810 in the height direction. In another embodiment, the sidewall of the funnel 810 is provided with an escape opening 813, and the blanking end 421 extends into the funnel 810 through the escape opening 813. By arranging the avoiding opening 813, the funnel 810 and the blanking end 421 are partially crossed in the height direction, and when the conveyor 400 runs at a high speed, the inner wall of the funnel 810 can play a certain blocking role in the lamp holder 600 moving transversely, which is beneficial to improving the processing efficiency of the lamp holder.

The lamp cap gluing device further comprises a supporting mechanism 820 located between the outlet and the receiving end 842 of the funnel 810, and the supporting mechanism 820 comprises a supporting member 821 and an elastic member. The supporters 821 are two oppositely arranged, and the supporters 821 have a clamping state and an opening state. The two supports 821 are respectively provided with a positioning surface 822 adapted to the shape of the circumference of the lamp cap 600. The resilient member drives the holding member 821 to return from the expanded state to the clamped state. In the clamped state, the space between the two supports 821 still allows the lamp cap 600 to enter. At the moment that the lamp head 600 falls on the platen 841, the two supporting members 821 are in a clamping state, the supporting mechanism 820 can prevent the lamp head 600 from tilting, and in the transverse moving process of the lamp head 600, under the action of the transverse moving mechanism 700, the two supporting members 821 overcome the elastic force of the elastic member to gradually open, so that the channel is opened for the lamp head 600 to move out. After the lamp cap 600 is removed from between the two supporters 821, the two supporters 821 are returned to the clamping state under the elastic force of the elastic member.

Referring to fig. 6, in order to facilitate the insertion of the lamp cap 600 into the holding mechanism 820, in the clamped state, a positioning space 823 is formed between the two positioning surfaces 822, and the two holding members 821 are further provided with guide surfaces 824 for guiding the lamp cap into the positioning space 823.

Specifically, in the lamphead transfer direction, the slit 844 includes a first equal-width section 845, a contraction section 846, and a second equal-width section 847 which are connected in sequence.

Referring to fig. 5, the first constant width section 845 is smaller than the outer diameter of the end cap 611 and extends to the receiving end 842, and when the lamp head 600 falls on the workbench 800, the lamp pins 612 are located in the first constant width section 845. The width of the constriction 846 is gradually reduced; during the movement of the lamp head 600 in the retraction section 846, the connection direction between the two corresponding lamp pins gradually coincides with the conveying direction. The second equal-width section 847 has a width 1-1.5 times the outer diameter of the lamp base and extends to the positioning end 843. The lamp pins in the second equal width section 847 are arranged substantially along the conveying direction.

The traversing mechanism 700 includes a clamping jaw cylinder 710, two mounts 720, a clamping roller set 730, and a traversing cylinder 740. The jaw cylinder 710 has two jaws 711.

The clamping roller set 730 includes four clamping rollers 731 with vertical axes, a pair of clamping rollers 731 is respectively mounted on each mounting base 720, and each clamping roller acts on different circumferential positions of the lamp head 600. The traverse cylinder 740 drives the gripper cylinder 710 to reciprocate in the lamp head 600 transfer direction.

Referring to fig. 4, the operation of the traversing mechanism 700 in one embodiment is as follows. When the lamp head 600 is dropped onto the receiving end 842, the two clamping jaws 711 are located at the positioning end 843 and are in a clamping state. First, the jaws 711 are opened and moved in the opposite direction of the arrow X in fig. 4 to the receiving end 842, where the upper half of the lamp head 600 is held in the holding mechanism 820 and the lower half of the lamp head 600 is located between the jaws 711. Then, the clamping jaw cylinder 710 drives the clamping roller set 730 to clamp the circumference of the lamp cap 600. Then, the traverse cylinder 740 pushes the grip roller set 730 to move to the positioning end 843 in the direction indicated by the arrow in fig. 3, and thus reciprocates in a cycle.

The lamp holder 600 is clamped through the clamping roller group 730, resistance of the lamp holder 600 in the process of adjusting the rotating angle can be reduced, production efficiency is improved, and the shell of the lamp holder 600 is protected from being damaged.

In order to prevent the lamp head 600 from tilting during the traversing process, the mounting base 720 is a flat plate-shaped structure, and two clamping roller sets 730 are arranged on the upper and lower sides of the plate-shaped structure respectively.

The lamp cap gluing device further comprises a second photoelectric sensor 850 for detecting the lamp cap 600 of the receiving end 842, and the clamping jaw air cylinder 710 and the transverse moving air cylinder 740 are controlled by the second photoelectric sensor 850.
