Technical Field

[0001] The invention relates to the technical field of lamp manufacturing and assembly, and in particular to a filament feeding component based on automatic assembly. Background Art

[0002] In the prior art, the feeding process of filament assembly refers to a filament feeding device disclosed in publication number CN109867100B, which specifically feeds the filament continuously and accurately without leaking or over-feeding. Another example is a filament feeding mechanism disclosed in publication number CN216835652U, which separates the filament through a secondary vibrating screen and then uses a suction nozzle to complete the feeding of a single filament. The common point of the above two technical solutions is that both use a disc vibrating screen to complete the initial feeding of the filament.

[0003] However, in combination with the above, it should be noted that: for the automatic assembly process of incandescent filaments, since incandescent filaments do not only adopt a columnar structure, for the more widely used double-helix structure filaments, there are uncontrollable phenomena of irregular feeding and material dropping during the feeding process, which urgently need to be improved.

[0004] To this end, this application proposes a solution. Summary of the invention

[0012] It is further configured as follows: the filament feeding belt, the lamp holder feeding belt and the finished product conveyor belt are all synchronous belt conveyor lines, and the filament feeding belt is a separate synchronous belt conveyor structure.

[0013] It is further configured as follows: an arc-shaped groove is opened on the material shifting rack, a DC motor is embedded and installed on the material shifting rack through the inner end of the arc-shaped groove, the output end of the DC motor is connected to the supporting arc plate, and a leveling pad flush with the bottom end of the discharge port is embedded on the supporting arc plate.

[0014] It is further configured that: the control panel is built with an integrated module, and the integrated module includes a filament illumination unit, a comparison and selection unit, an execution and control unit, a homing management unit and a processor that are communicatively connected to each other;

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention aims at the problem of irregular feeding and uncontrollable material dropping during the feeding process of the double helix filament: on the one hand, the double helix filament is selected in advance during the feeding and then the synchronous assembly interval with the lamp holder is set, so that the double helix filament and the lamp holder structure form a continuous combined assembly, ensuring regular feeding between the double helix filament and the lamp holder structure, and avoiding assembly missing caused by material dropping; on the other hand, the twisted wires of the double helix filament are separated before feeding, so that the double helix filament can be fed at a uniform speed to facilitate the regular feeding of the subsequent feeding; the combination of the two is mainly based on the intelligent feeding control of the integrated module, supplemented by the uniform and regular feeding, to jointly complete the automatic assembly of the filament and the lamp holder, thereby improving the processing efficiency;

[0019] 2. Before the double helix filament is fed regularly, the double helix filament is separated in advance to prevent the twisting phenomenon. Specifically, the double helix filament is intermittently fed into the separation box through the feeding hopper. The double helix filament entering the separation box will inevitably produce twisting phenomenon. Then, the separation box is vibrated as a whole under the driving action of the vibrating part that continuously vibrates linearly. The double helix filament inside the separation box can be gradually fed through the feeding trough. After reaching the top, it falls into the unloading trough through the unit wire feeding trough, the guide bar and the connecting trough. Under the continuous vibration effect, the double helix filament in the feeding trough is fed at a uniform speed, while the double helix filament in the unloading trough is unloaded at a uniform speed until it passes through the slope guide trough and rolls onto the filament feeding belt at a uniform speed.

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Reference Figure 1 - Fig.10As shown, the filament feeding assembly based on automatic assembly in this embodiment includes a rotary assembly table 5, a control panel is embedded on the rotary assembly table 5, an adsorption plate 6 with adsorption holes 9 evenly distributed in the middle of the bottom surface is installed on the rotary assembly table 5, welding structures for filament welding are installed on both sides of the rotary assembly table 5 corresponding to the adsorption plate 6, and a filament feeding mechanism 2, a lamp holder feeding structure 4 and a finished product conveyor belt 7 are tangentially arranged on the outer side of the rotary assembly table 5;

[0037] The welding structure is a welding head symmetrically arranged on both sides of the adsorption plate 6, and a pair of welding heads are arranged on both sides of each adsorption plate 6. During this process, the lamp holder body 8 can be continuously assembled with the filament while the rotary assembly table 5 is continuously rotating, and finally the welding process after the filament is assembled is achieved;

[0038] Reference Figure 6 - Figure 8 As shown, the filament feeding mechanism 2 includes a filament feeding belt 21 and a slope guide groove 22 connected to each other, and an intermittent sorting mechanism 3 for picking out defective filaments is embedded and installed on the filament feeding belt 21. The intermittent sorting mechanism 3 includes a side rotating seat 31 arranged perpendicularly to the filament feeding belt 21, and a driving motor a for driving the intermittent rotation thereof is installed outside the side rotating seat 31;

[0039] The outer ring side of the side rotating seat 31 is provided with a mounting base plate 32, and a material shifting frame 33 is radially mounted on one end of the mounting base plate 32 close to the feeding side, and a supporting arc plate 35 for storing filaments is rotatably mounted inside the material shifting frame 33. A material discharge port 34 is provided at the upper side position of the mounting base plate 32 corresponding to the material shifting frame 33, and an arc-shaped groove is provided on the material shifting frame 33, and a DC motor 36 is embedded and mounted on the material shifting frame 33 through the inner end of the arc-shaped groove;

[0040] The output end of the DC motor 36 is connected to the supporting arc plate 35, and a level pad 37 flush with the bottom end of the discharge port 34 is embedded on the supporting arc plate 35. During the normal filament conveying process, defective filaments are screened out and the defective filaments are sorted out by the material picking rack 33, while the normal filaments are conveyed normally through the filament feeding belt 21 to complete the assembly with the lamp holder body 8;

[0041] Reference Figure 6 and Fig.10 As shown, a lifting and aligning frame A23 vertically aligned with one of the adsorption plates 6 is installed at the end of the filament feeding belt 21, and the lifting and aligning frame A23 is used for lifting and assembling the filament. The lamp holder feeding structure 4 includes a lamp holder feeding belt 41 tangentially arranged with the rotary assembly table 5 and used for loading and conveying the lamp holder. A lifting and aligning frame B43 vertically aligned with one of the adsorption plates 6 is provided at the end of the lamp holder feeding belt 41;

[0042] The lifting and aligning frame B43 is used for lifting the lamp holder body 8 and is a matching body with the filament lifted by the lifting and aligning frame A23. After the lamp holder body 8 is intermittently conveyed by the lamp holder feeding belt 41, when it moves to the top of the lifting and aligning frame B43, the lifting and aligning frame B43 is immediately started to drive the lamp holder body 8 to move onto the adsorption plate 6, and the adsorption and fixation are completed through the adsorption holes 9 on the adsorption plate 6. During this process, the lamp holder feeding belt 41 is in a stopped state;

[0043] Similarly, when the filament is moved to the top of the lifting and positioning frame A23 through the filament feeding belt 21, the filament feeding belt 21 stops, the lifting and positioning frame A23 starts and drives the filament to move to the lamp holder body that is rotated and moved into position, and then the welding process is completed through the welding head. In this process, the filament can be effectively evenly fed and the assembly can be completed without distinction, avoiding the assembly dislocation or even failure caused by irregular feeding and material dropping.

[0044] Reference Figure 6 As shown, the filament feeding belt 21, the lamp holder feeding belt 41 and the finished product conveyor belt 7 are all synchronous belt conveyor lines, and the filament feeding belt 21 is a separate synchronous belt conveyor structure, which is configured to provide unobstructed conveyance of the filament during defect inspection, so that the filament can continue to be conveyed after defect sorting is completed;

[0045] In order to realize the continuous feeding and assembly of the double helix structure filament to prevent irregular feeding and material dropping, a control panel is specially provided. The control panel has an integrated module built in. The integrated module includes a filament inspection unit, a comparison selection unit, an execution control unit, a homing management unit and a processor that are connected to each other in communication;

[0046] A bird's-eye view camera is installed just above the filament feeding belt 21, which is used to obtain a bird's-eye view rolling video of the filament being transported. The filament inspection unit is used to obtain evaluation information of the bird's-eye view image of the filament being transported on the filament feeding belt 21, and send the evaluation information to the comparison and selection unit through the processor. The comparison and selection unit obtains a compliance signal and an abnormal signal based on the comparison and analysis results of the evaluation information and the bird's-eye view image of the normal filament being transported;

[0047] The comparative analysis process is as follows: the filament after feeding rolls out to the slope guide groove 22 and is transported through the filament feeding belt 21. The top-down camera completes the video capture of the filament rolling process and forms evaluation information. Since the filament unloading point and the drop point are at the same height, the rolling speed of each filament is the same. The starting rolling point of the filament at the same position is selected and the video image of one circle of rolling is recorded. The video image is overlapped and compared with the preset normal one-circle image. If a cross phenomenon occurs, an abnormal signal is generated, otherwise a compliance signal is generated.

[0048] The comparison and selection unit sends the compliance signal and the out-of-order signal to the execution control unit and the homing management unit, and the execution control unit receives the compliance signal and the out-of-order signal and takes corresponding guidance actions;

[0049] When the execution control unit receives the compliance signal, it sends the compliance signal to the filament feeding belt 21, the lamp holder feeding belt 41 and the driving motor a. The driving motor a drives the side rotating seat 31 to rotate, so that the discharge port 34 on the mounting substrate 32 is aligned with the filament feeding belt 21, and the filament is continuously fed without obstruction.

[0050] When the execution control unit receives the abnormal signal, the abnormal signal is sent to the filament feeding belt 21, the lamp holder feeding belt 41, the driving motor a and the DC motor 36. The DC motor 36 starts to drive the supporting arc plate 35 to rotate, and the leveling pad 37 outside the supporting arc plate 35 rotates to a position relative to the filament feeding direction, so that the filament moves into the groove on the material shifting frame 33 and falls into place.

[0051] The unqualified filament in the groove is clamped and fixed by the material-shifting rack 33 and the leveling pad 37, and then the driving motor a is started to drive the side rotating seat 31 to rotate. When the groove on the material-shifting rack 33 faces downward, the leveling pad 37 is reset to cause the filament to fall down, thereby completing the collection;

[0052] It should be noted that, during the feeding process: the homing management unit marks the time required for a single filament to undergo the "sorting" process as T1, marks the time period for completing the "sorting" and shifting to the top-lifting alignment frame A23 as T2, and marks the time period for moving the lamp holder body 8 from the filament feeding belt 41 to the adsorption plate 6 and rotating to the vertical position of the top-lifting alignment frame A23 as T3. During this process, the time required is always maintained as follows: T1+T2=T3;

[0053] Specifically, it is achieved by controlling the rotation speed of the drive motor a, the DC motor 36 and the rotary assembly table 5 and the feeding speed of the filament feeding belt 21 and the lamp holder feeding belt 41, thereby ensuring that the filament is always regularly docked and assembled with the lamp holder body 8 after sorting and feeding, thereby preventing the phenomenon of no-load assembly caused by material falling.

[0054] Basic principle: The present invention realizes combined assembly through the coordinated continuous feeding between the filament and the lamp holder structure. The specific content is: the double-helix structure filament is selected in advance during the feeding and then the synchronous assembly interval with the lamp holder is set, so that the double-helix structure filament and the lamp holder structure form a continuous combined assembly, thereby ensuring regular feeding between the double-helix structure and the lamp holder structure, and avoiding the phenomenon of assembly missing caused by material falling.

[0055] Embodiment 2: This embodiment is to further optimize the structure of the embodiment 1, which is to solve the problem of deformation and twisting of the filaments during the initial feeding process before assembly due to the softness of the filament structure itself:

[0056] Reference Figure 4 and Figure 5 As shown, the feed front end including the slope guide groove 22 is equipped with a twisted wire separation mechanism 1 for filament dispersion, the twisted wire separation mechanism 1 includes a separation box 101 and a vibration part 102, the inner wall of the separation box 101 is equipped with a feed trough 105, the outer wall of the separation box 101 is equipped with a feed trough 109, and the upper end of the feed trough 105 is equipped with a unit wire feeding trough 106;

[0057] The lower end of the unit wire feeding slot 106 is provided with a connecting slot 110 connected to the feeding slot 109, the end of the feeding slot 109 is vertically connected to the slope guide slot 22, a loading platform 103 is installed in the middle of the separation box 101, a feeding hopper 104 for uniformly loading filaments is installed at the upper end of the loading platform 103, and a guide fence 107 respectively connected to the unit wire feeding slot 106 and the connecting slot 110 is installed in the middle of the loading platform 103.

[0058] Basic principle: before the regular feeding of the filaments, the double helix filaments are separated in advance to prevent the twisting phenomenon. Specifically, the double helix filaments are intermittently fed into the separation box 101 through the feeding hopper 104. The double helix filaments entering the separation box 101 will inevitably produce twisting phenomenon, and then the separation box 101 is vibrated as a whole under the driving action of the vibration part 102 which continuously vibrates linearly;

[0059] The double helix filament in the separation box 101 can be progressively loaded through the loading trough 105, and after reaching the top, it falls into the unloading trough 109 through the unit wire feeding trough 106, the guide bar 107 and the connecting trough 110. Under the continuous vibration effect, the double helix filament in the loading trough 105 is loaded at a uniform speed, and the double helix filament in the unloading trough 109 is unloaded at a uniform speed until it passes through the slope guide groove 22 and rolls onto the filament feeding belt 21 at a uniform speed.

[0060] It is worth mentioning that: during the vibration separation process of the twisted wire, the double-helix filament first moves vertically along the feeding direction, then moves vertically from the upper trough 105 to the lower trough 109, and finally moves horizontally in the filament feeding belt 21 corresponding to the vertical direction, thereby achieving smooth short-time radial rolling, which is convenient for the inspection of double-helix filament defects.

[0061] Embodiment 3: This embodiment combines Embodiment 1 and Embodiment 2, referring to Figure 1 - Fig.10 As shown, the filament feeding method is constituted as follows, comprising the following steps:

[0062] S1: The double-helix filament is intermittently put into the separation box 101 through the feed hopper 104. The double-helix filament entering the separation box 101 will inevitably produce a twisted wire phenomenon, and then the separation box 101 is vibrated as a whole under the driving action of the vibrating part 102 that continuously vibrates linearly. The double-helix filament inside the separation box 101 can be gradually loaded through the loading trough 105, and after reaching the top, it falls into the unloading trough 109 through the unit wire feeding trough 106, the guide bar 107 and the connecting groove 110. Under the continuous vibration effect, the double-helix filament in the loading trough 105 is loaded at a uniform speed, and the double-helix filament in the unloading trough 109 is unloaded at a uniform speed until it passes through the slope guide groove 22 and rolls onto the filament feeding belt 21 at a uniform speed;

[0063] S2: After feeding, the filament rolls out toward the slope guide groove 22 and is transported through the filament feeding belt 21. The top camera takes video of the filament during rolling and forms evaluation information. Since the filament unloading point is at the same height as the drop point, the rolling speed of each filament is the same. The starting rolling point at the same position of the filament is selected and a video image of one circle of rolling is recorded. The video image is overlapped and compared with the preset normal one circle rolling image. If a cross phenomenon occurs, an abnormal signal is generated, otherwise a compliance signal is generated.

[0064] S3: When the execution control unit receives the compliance signal, the compliance signal is sent to the filament feeding belt 21, the lamp holder feeding belt 41 and the driving motor a. The driving motor a drives the side rotating seat 31 to rotate, so that the discharge port 34 on the mounting substrate 32 is aligned with the filament feeding belt 21, so that the filament is continuously fed without obstruction;

[0065] S4: synchronously with S3, when the execution control unit receives the abnormal signal, the abnormal signal is sent to the filament feeding belt 21, the lamp holder feeding belt 41, the driving motor a and the DC motor 36, the DC motor 36 starts to drive the supporting arc plate 35 to rotate, and the level pad 37 outside the supporting arc plate 35 rotates to a position relative to the filament feeding direction, thereby achieving the purpose of moving the filament into the groove on the material shifting rack 33 and landing, and the unqualified filament in the groove is clamped and fixed by the material shifting rack 33 and the level pad 37, and then the driving motor a is started to drive the side rotating seat 31 to rotate, and when the groove on the material shifting rack 33 faces downward, the level pad 37 resets to cause the filament to fall and complete the collection;

[0066] S5: The homing management unit marks the time required for a single filament to undergo a "sorting" process as T1, marks the time period for completing the "sorting" and shifting it to the jacking alignment frame A23 as T2, and marks the time period for moving the lamp holder body 8 from the filament feeding belt 41 to the adsorption plate 6 and rotating it to the vertical position of the jacking alignment frame A23 as T3. The time required in this process is always maintained at: T1+T2=T3, which is specifically achieved by controlling the rotation speed of the drive motor a, the DC motor 36, and the rotary assembly table 5, and the feeding speed of the filament feeding belt 21 and the lamp holder feeding belt 41, thereby ensuring that the filament is always regularly docked and assembled with the lamp holder body 8 after the sorting and feeding is completed, thereby preventing the phenomenon of empty assembly caused by material falling;

[0067] S6: After the lamp holder body 8 and the double-helix filament are assembled, the rotary assembly table 5 continues to rotate until it lands on the finished product conveyor belt 7 and stops, and the adsorption holes 9 on the adsorption plate 6 are released from adsorption, and finally the assembly of the entire lamp is completed.

[0068] To sum up: on the one hand, by pre-selecting the double-helix structure filament during delivery and then setting the synchronous assembly interval with the lamp holder, a continuous combination assembly is formed between the double-helix structure filament and the lamp holder structure, ensuring regular feeding between the double-helix filament and the lamp holder structure, and avoiding the phenomenon of assembly missing caused by material falling; on the other hand, by separating the twisted wires before feeding the double-helix filament, the double-helix filament can be fed at a uniform speed to facilitate the subsequent regular feeding; the combination of the two is mainly based on the intelligent feeding control of the integrated module, supplemented by uniform and regular feeding, to complete the automatic assembly of the filament and the lamp holder.
