Description

Technical Field

[0001] The present application relates to the field of bending and cutting equipment for metal profiles, and in particular to a device for bending and cutting a grating-specific lamp. Background Art

[0002] Safety light barriers are mainly used to protect the work area from intrusion by foreign objects and to ensure normal operation within the work area. When a foreign intruder triggers the safety light barrier, it will immediately alarm or stop the current work to ensure the safety of personnel and equipment. LED lamp beads are commonly used as emitting components of light barriers, with large useful quantities and high requirements for size and position consistency.

[0003] In the related art, a lamp bead is usually composed of a lamp holder 001 and a lamp foot 002. Specifically, during processing and production, the lamp foot 002 is bent into a certain angle by a corresponding bending device, and then the lamp foot 002 is cut into a corresponding size by a corresponding cutting device, and then the processed lamp bead is packaged.

[0004] For lamp beads whose lamp caps 001 are made of metal, such lamp beads need to maintain a specific posture for packaging after processing. This is because the packaging tape 003 used to package the lamp beads is provided with a corresponding packaging groove 004. When the lamp beads are packaged on the packaging tape 003, the lamp pins 002 of the lamp beads need to be inserted into the packaging groove 004 first to complete the packaging. The state of the lamp bead after packaging is: after the lamp pins 002 are inserted into the packaging groove 004, the lamp cap 001 is located outside the packaging groove 004, that is, when the lamp beads are packaged, the lamp pins 002 need to be kept facing downward and the lamp cap 001 facing upward, so as to ensure that the lamp pins 002 can smoothly enter the packaging groove 004 of the packaging tape 003.

[0005] However, since the lamp head 001 of the lamp bead is made of metal, the lamp head 001 is relatively heavy, resulting in a "top-heavy" situation. As a result, when the lamp bead is transported to the packaging belt 003 after the bending and cutting process is completed, the lamp head 001 is usually facing downward and the lamp foot 002 is facing upward. This makes it impossible for the lamp foot 002 to be smoothly inserted into the packaging groove 004 of the packaging belt 003. At this time, it is necessary to manually adjust the posture of the lamp bead and turn the entire lamp bead over so that the lamp foot 002 faces downward and the lamp head 001 faces upward, so as to ensure that the lamp foot 002 is smoothly inserted into the packaging groove 004 of the packaging belt 003 to complete the packaging of the lamp bead.

[0006] Since LED lamp beads are commonly used as emitting components of gratings, there is a large demand for them. If each lamp bead needs to be manually flipped after processing, it will consume a lot of manpower and does not meet the requirements of the new industry. At the same time, manual labor is prone to fatigue when working for a long time, which can easily lead to reduced efficiency of lamp bead flipping, and sometimes the flipping may not be in place, which is not conducive to the daily processing and production of lamp beads. Summary of the invention

[0007] The present application provides a device for bending and cutting grating-specific lamps, the purpose of which is to improve the efficiency of packaging lamp beads into packaging tapes after they have been processed, while ensuring the accuracy of lamp bead flipping, which is beneficial to the daily processing and production of lamp beads.

[0008] The present application provides a device for bending and cutting a grating-specific lamp, which adopts the following technical solution:

[0009] A device for bending and cutting a grating-specific lamp, comprising a bottom plate, a first base and a second base, wherein the first base and the second base are fixed to the left and right ends of the bottom plate, a forming roller is installed on the first base, a bending roller and a cutting roller are installed on the side wall of the second base at intervals, the bending roller and the cutting roller are located at the same horizontal height, the forming roller is located above the bending roller and the cutting roller, the forming roller is used to fix a paper tape, the forming roller and the bending roller cooperate with each other to bend lamp beads on the paper tape, and the forming roller and the cutting roller cooperate with each other to cut off excess paper tape after the lamp beads are bent;

[0010] A discharge plate and a conveying slide are provided between the top of the second base and the forming roller, the discharge plate is used to transfer the cut lamp beads to the conveying slide, the bottom of the conveying slide is connected to an adjustment channel, the adjustment channel is used to flip and adjust the posture of the lamp beads, the side of the adjustment channel away from the conveying slide is connected to a conveying channel, the bottom of the conveying channel is connected to a packaging belt, the conveying channel is used to convey the lamp beads with adjusted postures into the packaging belt for packaging.

[0011] By adopting the above technical solution, in this setting mode, the lamp beads will fall into the adjustment channel and be automatically adjusted after cutting. This makes it unnecessary to manually flip the lamp beads one by one after cutting, which can greatly reduce manual work and effectively solve the problem of reduced lamp bead flipping efficiency and flipping accuracy caused by long-term manual work, which is beneficial to ensure the daily processing and production of lamp beads.

[0012] Preferably, a bending surface is formed between the forming roller and the bending roller, and the bending surface is used to extrude and bend the lamp beads.

[0013] By adopting the above technical solution, specifically, when bending the lamp bead, the forming roller and the bending roller are tangent to each other, and the distance between the two end surfaces of the forming roller and the bending roller forms a bending surface, which is the diameter of the lamp foot; when the paper tape carrying the lamp bead enters the tangent surface of the forming roller and the bending roller, the lamp foot of the lamp bead is squeezed into 90 degrees by the bending surface to complete the bending of the lamp bead. The specific bending length of the lamp foot can be controlled by adjusting the distance between the two end surfaces of the forming roller and the bending roller.

[0014] Preferably, the cutting roller is formed with an annular cutting edge along its circumference, the cutting edge penetrates into the forming roller, and the cutting edge is used to cut excess paper tape.

[0015] By adopting the above technical solution, when the paper tape enters the tangent surface between the forming roller and the cutting roller, the contact surface between the paper tape and the forming roller is cut off by the cutting edge, thereby completing the cutting of the excess paper tape.

[0016] Preferably, a first barb plate is integrally formed at the front end of the top of the discharge plate, and the first barb plate extends into the first slot on the side of the forming roller, and the first barb plate is used to push the finished lamp beads out to the conveying slide.

[0017] By adopting the above technical solution, when the finished lamp beads after cutting follow the forming roller to the position of the first barb plate, the lamp beads will be blocked by the first barb plate and ejected out of the forming roller. The finished lamp beads ejected out of the forming roller will fall onto the conveying slide and fall into the adjustment channel through the conveying slide to adjust their posture.

[0018] Preferably, the regulating channel is provided with an inlet at the top and an outlet at the bottom, the inlet is connected to the conveying slide, and the outlet is connected to the conveying channel;

[0019] The adjustment channel is provided with an articulated limiting mechanism, a driving mechanism and a stopping and unlocking mechanism. The articulated limiting mechanism is used to limit the lamp head of the lamp bead and set the lamp head to an articulated mode; the driving mechanism is used to push the lamp pin to rotate; the stopping and unlocking mechanism is used to stop the lamp pin under the lamp head and release the limiting effect of the articulated limiting mechanism on the lamp head.

[0020] By adopting the above technical solution, the posture of the lamp beads is adjusted by using an articulated limiting mechanism, a driving mechanism and a stop and unlocking mechanism, so that the lamp beads can fall from the exit of the adjustment channel into the conveying channel in the posture of "lamp feet facing down and lamp head facing up", and the conveying channel sends the adjusted lamp beads into the packaging belt for packaging.

[0021] Preferably, the hinge limiting mechanism includes a first wedge, a second wedge, and a third wedge. The first wedge, the second wedge, and the third wedge together form a "U" - shaped structure. The first wedge is horizontally arranged, and both its left and right ends are wedge - shaped. The second wedge is vertically arranged, and both its upper and lower ends are wedge - shaped. The third wedge is horizontally arranged. The third wedge is located above the first wedge, and the second wedge is located between the first wedge and the third wedge. One end of the third wedge close to the second wedge is wedge - shaped. The upper and lower ends of the second wedge are in wedge - shaped fit with the third wedge and the first wedge respectively;

[0022] When the lamp bead falls into the adjustment channel, the first wedge, the second wedge, and the third wedge are all located in front of the lamp bead. The lamp head presses the first wedge, and the first wedge moves towards the second wedge. While sliding, the first wedge drives the second wedge to move upward. While the second wedge moves upward, it drives the third wedge to move towards the lamp head. An articulated shaft is integrally formed at one end of the third wedge close to the lamp head. The articulated shaft is inserted into the lamp head, and the articulated shaft is used to limit the lamp head, and the lamp head rotates around the articulated shaft.

[0023] By adopting the above - mentioned technical solution, a circular hole adapted to the end of the articulated shaft is opened on the front of the lamp head. The third wedge moves towards the lamp head until the articulated shaft is inserted into the through - hole on the front of the lamp head. In this state, the lamp head is limited by the articulated shaft and cannot continue to descend. At the same time, the articulated shaft extends into the through - hole of the lamp head, and the lamp bead can rotate around the articulated shaft, thereby realizing the hinge limiting function of the lamp head through the articulated shaft.

[0024] Preferably, the driving mechanism includes a fourth wedge, a fifth wedge, and a sixth wedge. The fourth wedge, the fifth wedge, and the sixth wedge together form a "U" - shaped structure. The fourth wedge is horizontally arranged, and both its left and right ends are wedge - shaped. The fifth wedge is vertically arranged, and both its upper and lower ends are wedge - shaped. The sixth wedge is horizontally arranged. The sixth wedge is located above the fourth wedge, and the fifth wedge is located between the fourth wedge and the sixth wedge. One end of the sixth wedge close to the fifth wedge is wedge - shaped. The upper and lower ends of the fifth wedge are in wedge - shaped fit with the sixth wedge and the fourth wedge respectively. The sixth wedge corresponds to the position of the lamp pin;

[0025] When the lamp bead falls into the adjustment channel, the fourth wedge, the fifth wedge, and the sixth wedge are all located on the side of the lamp bead. While pressing the first wedge, the lamp head also presses on the fourth wedge, driving the fourth wedge to move towards the fifth wedge. While sliding, the fourth wedge drives the fifth wedge to move upward. The fifth wedge presses the sixth wedge to move towards the lamp pin, and the sixth wedge pushes the lamp pin to rotate.

[0026] By adopting the above technical solution, the sixth wedge is used to push the lamp pin to rotate so that it rotates to below the lamp head.

[0027] Preferably, the stop and unlock mechanism comprises a seventh wedge block and an eighth wedge block, the seventh wedge block and the eighth wedge block are located below the fourth wedge block, the eighth wedge block is located above the seventh wedge block, the seventh wedge block is horizontally arranged, and its end away from the lamp holder is in a wedge shape, the eighth wedge block is horizontally arranged, and the eighth wedge block is in an inverted "L" shape as a whole, the end of the eighth wedge block connected to the seventh wedge block is in a wedge shape, and the end of the eighth wedge block away from the seventh wedge block is connected to the third wedge block;

[0028] The seventh wedge block is used to stop the lamp pin, and the seventh wedge block is used to drive the eighth wedge block to slide in a direction away from the lamp holder, and the eighth wedge block is used to drive the third wedge block to separate from the lamp holder.

[0029] By adopting the above technical solution, when the lamp pin is driven by the sixth wedge block to rotate to the bottom of the lamp head, it corresponds to the seventh wedge block. Since the lamp pin has inertia when it rotates downward, this causes the lamp pin to continue to rotate when it rotates to the bottom of the lamp head. At this time, the seventh wedge block stops the lamp pin, so that the lamp pin stops under the lamp head. At the same time, the lamp pin acts on the seventh wedge block, so that the seventh wedge block moves in the direction close to the eighth wedge block, and the eighth wedge block is squeezed by the seventh wedge block, so that the eighth wedge block moves away from the lamp bead. While the eighth wedge block moves away from the lamp bead, it simultaneously drives the third wedge block to move away from the lamp bead, and then drives the hinge shaft to disengage from the lamp head through the eighth wedge block, thereby releasing the lock on the lamp head. In this state, the posture of the lamp bead is "the lamp pin is facing down and the lamp head is facing up".

[0030] After the lamp beads are unlocked, they fall into the conveying channel from the outlet of the adjustment channel, and are finally conveyed to the packaging belt through the conveying channel to complete the packaging.

[0031] Preferably, the forming roller is slidably mounted on the first base in a vertical direction;

[0032] A lifting seat is provided above the first base, the forming roller is connected to the lifting seat through a horizontal roller bearing, an internal threaded hole is provided on the lifting seat, a screw handle is inserted through the top of the lifting seat, the screw handle consists of a screw and a handle, the screw is vertically inserted into the internal threaded hole, the handle is installed on the top of the screw, guide columns are fixed on the left and right ends of the top of the first base in the vertical direction, through holes compatible with the guide columns are penetrated on the left and right sides of the lifting seat, the bottoms of the two guide columns are respectively connected to the top of the first base through the corresponding through holes on the lifting seat, and a reinforcing plate connecting the two guide columns is horizontally fixed between the tops of the two guide columns.

[0033] By adopting the above technical solution, the forming roller is slidably installed on the first base in the vertical direction. The purpose of this is to raise the forming roller when the paper tape is installed on the forming roller, so that a gap is generated between the forming roller and the bending roller, so as to facilitate the paper tape to be fed into the machine; after the paper tape is fed into the machine, the forming roller is lowered so that it is tangent to the bending roller and reaches the working position.

[0034] Preferably, a paper baffle plate is provided on the top of the discharge plate, one side of the paper baffle plate is fastened to the top of the discharge plate, and two second hook plates are integrally formed on the side wall of the paper baffle plate, and the two second hook plates are spaced apart, and the forming roller is provided with two second slots along its circumference, and the two second slots are spaced apart, and the two second hook plates on the paper baffle plate extend and are respectively inserted into the two second slots.

[0035] By adopting the above technical solution, the paper stopper plate is fastened to the forming roller by using two second barb plates and a second slot. After the lamp beads are cut, the remaining excess paper tape will follow the forming roller to the position of the second barb plate, and the excess paper tape will be blocked by the paper stopper plate and separated from the forming roller and fall to the ground, thereby effectively preventing the excess paper tape from re-entering the machine and interfering with the normal cutting of the lamp beads.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. After the lamp beads are cut, they will fall into the adjustment channel and automatically adjust. This means that after the lamp beads are cut, there is no need to manually flip them one by one, which can greatly reduce manual work and effectively solve the problem of reduced lamp bead flipping efficiency and accuracy caused by long-term manual work, which is conducive to ensuring the daily processing and production of lamp beads;

[0038] 2. Use the articulated limit mechanism, drive mechanism and stop unlocking mechanism to adjust the posture of the lamp beads, so that the lamp beads can fall into the conveying channel from the exit of the adjustment channel in the posture of "lamp feet facing down and lamp head facing up", and the conveying channel will send the adjusted lamp beads into the packaging belt for packaging;

[0039] 3. A circular hole matching the end of the third wedge is opened on the front of the lamp holder, and the third wedge moves toward the lamp holder until the hinge shaft is inserted into the through hole on the front of the lamp holder. In this state, the lamp holder is limited by the hinge shaft and cannot continue to drop. At the same time, the hinge shaft extends into the through hole of the lamp holder, and the lamp bead can rotate with the hinge shaft as the axis, thereby realizing the hinge limit effect on the lamp holder through the hinge shaft.

DETAILED DESCRIPTION

[0047] The following is combined with Figure 2 -Attached Figure 6 , further details of this application are given.

[0048] Example:

[0049] The present application embodiment discloses a device for bending and cutting a grating-specific lamp, referring to Figure 2 and Figure 3 , including a rectangular bottom plate 1, a first base 2 and a second base 3. The bottom plate 1 is arranged horizontally, and the first base 2 and the second base 3 are welded to the left and right ends of the top of the bottom plate 1. A molding roller 4 is installed on the first base 2, and a bending roller 5 and a cutting roller 6 are installed on the side wall of the second base 3 at intervals. The bending roller 5 and the cutting roller 6 are located at the same horizontal height, and the molding roller 4 is located above the bending roller 5 and the cutting roller 6. The LED lamp beads are installed on the corresponding paper tape, and the molding roller 4 is used to fix the paper tape. At the same time, the molding roller 4 and the bending roller 5 cooperate with each other to bend the lamp beads on the paper tape, and the molding roller 4 and the cutting roller 6 cooperate with each other to cut off the excess paper tape after the lamp beads are bent.

[0050] Reference Figure 2 and Figure 3A discharge plate 7 and a conveying slide 8 are provided between the top of the second base 3 and the forming roller 4. After the lamp beads are cut from the paper tape through the cutting surface, the cut lamp beads are transferred to the conveying slide 8 through the discharge plate 7. In this state, the lamp beads fall onto the conveying slide 8 with the lamp head facing down and the lamp feet facing up. The bottom of the conveying slide 8 is connected with an adjustment channel 9, and the adjustment channel 9 is used to flip and adjust the posture of the lamp beads, so that the lamp beads change from the lamp head facing down and the lamp feet facing up to the posture with the lamp feet facing down and the lamp head facing up. A conveying channel 10 is provided on the side of the adjustment channel 9 away from the conveying slide 8. After the posture of the lamp beads is adjusted by the adjustment channel 9, they fall into the conveying channel 10. The bottom of the conveying channel 10 is connected with the packaging belt. After the posture of the lamp beads is adjusted, they fall directly into the packaging belt through the conveying channel 10 for packaging.

[0051] With this arrangement, the lamp beads will fall into the adjustment channel 9 and be automatically adjusted after cutting. This means that there is no need to manually flip the lamp beads one by one after cutting, which can greatly reduce manual work and effectively solve the problem of reduced lamp bead flipping efficiency and accuracy caused by long-term manual work, which is beneficial to ensure the daily processing and production of lamp beads.

[0052] Reference Figure 2 and Figure 3 Specifically, a plurality of pins are evenly installed on the periphery of the forming roller 4. These pins are used to fix the paper tape carrying the LED lamp beads. The paper tape is provided with circular through holes that match these pins. When installing, the pins on the forming roller 4 are inserted into the through holes on the paper tape one by one to fix the paper tape on the forming roller 4. A bending surface 11 is formed between the forming roller 4 and the bending roller 5, and the lamp beads are squeezed and bent by the bending surface 11. A cutting surface is formed between the forming roller 4 and the cutting roller 6, and the lamp beads are cut by the cutting surface.

[0053] Specifically, when bending the lamp bead, the forming roller 4 and the bending roller 5 are tangent to each other, and the distance between the side end face of the forming roller 4 and the side end face of the bending roller 5 forms a bending surface 11, and the distance between the two end faces is the diameter of the lamp foot; when the paper tape carrying the lamp bead enters the tangent surface of the forming roller 4 and the bending roller 5, the lamp foot of the lamp bead is squeezed into 90 degrees by the bending surface 11 to complete the bending of the lamp bead. The specific bending length of the lamp foot can be controlled by adjusting the distance between the two end faces of the forming roller 4 and the bending roller 5.

[0054] Reference Figure 3 and Figure 4Specifically, the forming roller 4 and the cutting roller 6 are tangent to each other, and the excess paper tape is cut off by the cutting roller 6 after the lamp bead is bent. The cutting roller 6 is formed with an annular cutting edge 12 along its circumference, and the cutting edge 12 penetrates into the forming roller 4. When the paper tape enters the tangent surface between the forming roller 4 and the cutting roller 6, the contact surface between the paper tape and the forming roller 4 is cut off by the cutting edge 12, thereby completing the cutting of the excess paper tape.

[0055] Furthermore, the forming roller 4 is slidably mounted on the first base 2 in the vertical direction. The purpose of this is to raise the forming roller 4 when the paper tape is mounted on the forming roller 4, so that a gap is generated between the forming roller 4 and the bending roller 5, so as to facilitate feeding the paper tape into the machine; after the paper tape is fed into the machine, the forming roller 4 is lowered so that it is tangent to the bending roller 5 and reaches the working position.

[0056] Reference Figure 2 and Figure 3 Specifically, a lifting seat 20 is provided above the first base 2, and the forming roller 4 is connected to the lifting seat 20 through a horizontal roller bearing. An internal threaded hole 21 is provided on the lifting seat 20, and a screw handle 22 is inserted through the top of the lifting seat 20. The screw handle 22 consists of a screw and a handle. The screw is vertically inserted into the internal threaded hole 21 on the lifting seat 20, and the handle is installed on the top of the screw. When the forming roller 4 is lifted or lowered, the lifting seat 20 can be driven to be lifted or lowered by rotating the screw through the handle, and the forming roller 4 can be driven to be lifted or lowered synchronously through the lifting seat 20.

[0057] Reference Figure 2 Furthermore, guide columns 23 are welded in the vertical direction at both left and right ends of the top of the first base 2, and through holes compatible with the guide columns 23 are penetrated on both left and right sides of the lifting seat 20. The bottoms of the two guide columns 23 pass through the corresponding through holes on the lifting seat 20 and are connected to the top of the first base 2. A reinforcing plate 24 connecting the two guide columns 23 is horizontally welded between the tops of the two guide columns 23.

[0058] Reference Figure 2 and Figure 4 Specifically, a first barb plate 13 is integrally formed at the front end of the top of the discharge plate 7, and the first barb plate 13 extends into the first slot 14 on the side of the molding roller 4. When the finished lamp beads after cutting follow the molding roller 4 to the position of the first barb plate 13, the lamp beads will be blocked by the first barb plate 13 and ejected from the molding roller 4. The finished lamp beads ejected from the molding roller 4 will fall onto the conveying slide 8, and then fall into the adjustment channel 9 through the conveying slide 8 to adjust their posture.

[0059] Reference Figure 2Furthermore, a paper baffle plate 25 is provided on the top of the discharge plate 7. The paper baffle plate 25 is an "L"-shaped structure as a whole. One side of the paper baffle plate 25 is fastened to the top of the discharge plate 7 in the horizontal direction by bolts, and the side wall on the other side is integrally formed with two second hook plates 26, and the two second hook plates 26 are spaced apart. At the same time, two second card slots 27 are provided along the circumference of the forming roller 4, and the two second card slots 27 are spaced apart. The two second hook plates 26 on the paper baffle plate 25 extend and are respectively inserted into the two second card slots 27. The paper baffle plate 25 is fastened to the forming roller 4 by the two second hook plates 26 and the second card slots 27. After the lamp beads are cut, the remaining excess paper tape will follow the forming roller 4 to the position of the second hook plate 26, and the excess paper tape will be blocked by the paper baffle plate 25, and it will be separated from the forming roller 4 and fall to the ground, and then the paper baffle plate 25 can effectively prevent the excess paper tape from re-entering the machine to interfere with the normal cutting of the lamp beads.

[0060] Reference Figure 2 and Figure 5 Specifically, an inlet 15 is provided at the top of the regulating channel 9 and an outlet 16 is provided at the bottom. The inlet 15 is connected to the conveying slide 8 , and the outlet 16 is connected to the conveying channel 10 .

[0061] Reference Figure 2 , Figure 5 as well as Figure 6 The adjustment channel 9 is provided with an articulated limit mechanism 17, a driving mechanism 18 and a stop unlocking mechanism 19. After the lamp beads are cut, they are sent to the adjustment channel 9 through the conveying slide 8. At this time, the posture of the lamp beads is "the lamp head faces down and the lamp foot faces up".

[0062] The articulated limiting mechanism 17 is used to limit the lamp head of the lamp bead, and at the same time, the lamp head is set to an articulated mode. The purpose of this is to facilitate the rotation of the lamp bead, so that it changes from "the lamp head facing down, the lamp foot facing up" to "the lamp foot facing down, the lamp head facing up";

[0063] After the lamp head is limited by the articulated limiting mechanism 17, in this state, "the lamp head faces downwards and the lamp foot faces upwards", and the lamp foot is above the lamp head. The driving mechanism 18 is used to push the lamp foot to rotate so that the lamp foot rotates to the bottom of the lamp head. In this state, "the lamp foot faces downwards and the lamp head faces upwards";

[0064] The stop and unlock mechanism 19 is used to stop the lamp pin when the lamp pin rotates to the bottom of the lamp head, and at the same time release the limiting effect of the hinged limiting mechanism 17 on the lamp head. In this state, the lamp bead can fall into the conveying channel 10 from the outlet 16 of the adjustment channel 9 in the posture of "lamp pin facing down and lamp head facing up", and the conveying channel 10 will send the adjusted lamp bead into the packaging belt for packaging.

[0065] Reference Figure 5 and Figure 6, specifically, the articulated limiting mechanism 17 includes a first wedge 171, a second wedge 172, and a third wedge 173. The first wedge 171, the second wedge 172, and the third wedge 173 as a whole form a "U" - shaped structure. The first wedge 171 is horizontally arranged, and both its left and right ends are wedge - shaped. The second wedge 172 is vertically arranged, and both its upper and lower ends are also wedge - shaped. The third wedge 173 is horizontally arranged. The third wedge 173 is located above the first wedge 171, the second wedge 172 is located between the first wedge 171 and the third wedge 173, and one end of the third wedge 173 close to the second wedge 172 is wedge - shaped. The upper and lower ends of the second wedge 172 are in wedge - shaped fit with the third wedge 173 and the first wedge 171 respectively.

[0066] Referring to Figure 5 and Figure 6 , when the lamp bead falls onto the adjustment channel 9, the first wedge 171, the second wedge 172, and the third wedge 173 are all located in front of the lamp bead. The bottom of the lamp head first presses on the first wedge 171, causing it to move in the direction close to the second wedge 172. While the first wedge 171 slides, it jacks up the second wedge 172 upward. By the second wedge 172 pressing on the third wedge 173, the third wedge 173 moves in the direction close to the lamp head. A round hole is provided on the front of the lamp head. An articulated shaft 28 is integrally formed in the horizontal direction on the third wedge 173 in the direction close to the lamp head. The third wedge 173 moves in the direction close to the lamp head until the articulated shaft 28 is inserted into the through - hole on the front of the lamp head. In this state, the lamp head is limited by the articulated shaft 28 and cannot continue to descend. At the same time, the articulated shaft 28 extends into the through - hole of the lamp head, and the lamp bead can rotate around the articulated shaft 28, thereby realizing the articulated limiting function for the lamp head through the articulated shaft 28.

[0067] Referring to Figure 5 and Figure 6 , the driving mechanism 18 includes a fourth wedge 181, a fifth wedge 182, and a sixth wedge 183. The fourth wedge 181, the fifth wedge 182, and the sixth wedge 183 as a whole form a "U" - shaped structure. The fourth wedge 181 is horizontally arranged, and both its left and right ends are wedge - shaped. The fifth wedge 182 is vertically arranged, and both its upper and lower ends are also wedge - shaped. The sixth wedge 183 is horizontally arranged. The sixth wedge 183 is located above the fourth wedge 181, the fifth wedge 182 is located between the fourth wedge 181 and the sixth wedge 183, and one end of the sixth wedge 183 close to the fifth wedge 182 is wedge - shaped. The upper and lower ends of the fifth wedge 182 are in wedge - shaped fit with the sixth wedge 183 and the fourth wedge 181 respectively. The sixth wedge 183 corresponds to the position of the lamp pin.

[0068] When the lamp bead falls into the adjustment channel 9, the fourth wedge 181, the fifth wedge 182 and the sixth wedge 183 are all located on the side of the lamp bead. When the bottom of the lamp holder is pressed onto the first wedge 171, the side wall of the lamp holder is pressed onto the fourth wedge 181, so that the fourth wedge 181 moves toward the direction close to the fifth wedge 182. When the fourth wedge 181 slides, it pushes the fifth wedge 182 upward, and the sixth wedge 183 is pressed by the fifth wedge 182, so that the sixth wedge 183 moves toward the direction close to the lamp pin, until the sixth wedge 183 pushes the lamp pin to rotate. Then, the sixth wedge 183 pushes the lamp pin to rotate, so that it rotates to the bottom of the lamp holder.

[0069] Reference Figure 5 and Figure 6 The stop unlocking mechanism 19 includes a seventh wedge block 191 and an eighth wedge block 192. The seventh wedge block 191 and the eighth wedge block 192 are located below the fourth wedge block 181, and the eighth wedge block 192 is located above the seventh wedge block 191. The seventh wedge block 191 is arranged horizontally, and its end away from the lamp holder is in a wedge shape. The eighth wedge block 192 is arranged horizontally, and the eighth wedge block 192 is in an inverted "L" shape as a whole. The end of the eighth wedge block 192 connected to the seventh wedge block 191 is in a wedge shape, and the end of the eighth wedge block 192 away from the seventh wedge block 191 is connected to the third wedge block 173 through a corresponding connecting rod.

[0070] When the lamp pin is driven by the sixth wedge block 183 and rotates to the bottom of the lamp head, it corresponds to the seventh wedge block 191. Since the lamp pin has inertia when rotating downward, the lamp pin will continue to rotate when it rotates to the bottom of the lamp head. At this time, the seventh wedge block 191 stops the lamp pin and stops it under the lamp head. At the same time, the lamp pin acts on the seventh wedge block 191, so that the seventh wedge block 191 moves toward the direction close to the eighth wedge block 192, and the eighth wedge block 192 is squeezed by the seventh wedge block 191, so that the eighth wedge block 192 moves away from the lamp bead. While the eighth wedge block 192 moves away from the lamp bead, it simultaneously drives the third wedge block 173 to move away from the lamp bead, and then drives the hinge shaft 28 to disengage from the lamp head through the eighth wedge block 192, thereby releasing the lock on the lamp head. In this state, the posture of the lamp bead is "the lamp pin is facing down and the lamp head is facing up".

[0071] After the lamp beads are unlocked, they fall into the conveying channel 10 from the outlet 16 of the adjustment channel 9 and are finally conveyed to the packaging belt through the conveying channel 10 to complete the packaging.

[0072] In this embodiment, the positions of the seventh wedge block 191 and the first wedge block 171 on the horizontal plane are staggered to ensure that the seventh wedge block 191 can smoothly stop the lamp pin when the lamp pin rotates to below the lamp head.

[0073] In this embodiment, the inclination angles of the conveying slide 8, the adjustment channel 9 and the conveying channel 10 are kept consistent. The purpose of this is to ensure that the angle of the lamp beads remains unchanged during the process of being conveyed to the packaging belt after the posture is adjusted, so as to ensure that the lamp beads can smoothly enter the packaging belt for packaging.

[0074] In this embodiment, the articulated limiting mechanism 17, the driving mechanism 18 and the stop unlocking mechanism 19 are all reset by corresponding springs, which is a conventional technical means and will not be described in detail here.

[0075] In the present embodiment, the conveying slide 8 is tilted, and in order to ensure that the conveying slide 8 can accurately convey the lamp beads to the adjustment channel 9, the spacing size of the conveying slide 8 is adapted to the size of the lamp holder. The purpose of this is that when the lamp beads fall onto the conveying slide 8, their "lamp head facing down, lamp feet facing up" posture will not be tilted or offset during the process of being conveyed to the adjustment channel 9, thereby effectively ensuring that the posture of the lamp beads when falling into the adjustment channel 9 is "lamp head facing down, lamp feet facing up" verticality, so as to ensure the subsequent flipping of the lamp beads. At the same time, the spacing size of the conveying channel 10 is also adapted to the size of the lamp holder. The purpose of this is that when the lamp beads are adjusted through the adjustment channel 9, their "lamp feet facing down, lamp head facing up" posture will not be angularly offset during the process of being conveyed to the packaging belt, thereby effectively ensuring that the lamp beads are smoothly packaged into the packaging belt.

[0076] To further ensure that the lamp beads are successfully packaged into the packaging belt, the length of the conveying slide 8 and the conveying channel 10 can be shortened according to the specific situation to ensure that the lamp beads can quickly enter the adjustment channel 9 for posture adjustment and can quickly enter the packaging belt for packaging.

[0077] The implementation principle of the device for bending and cutting a grating-specific lamp in the embodiment of the present application is as follows:

[0078] The LED lamp beads are mounted on the corresponding paper tape, and the forming roller 4 is used to fix the paper tape. At the same time, the forming roller 4 and the bending roller 5 cooperate with each other to bend the lamp beads on the paper tape, and the forming roller 4 and the cutting roller 6 cooperate with each other to cut off the excess paper tape after the lamp beads are bent.

[0079] A discharge plate 7 and a conveying slide 8 are provided between the top of the second base 3 and the forming roller 4. After the lamp beads are cut from the paper tape through the cutting surface, the cut lamp beads are transferred to the conveying slide 8 through the discharge plate 7. In this state, the lamp beads fall onto the conveying slide 8 with the lamp head facing down and the lamp feet facing up. The bottom of the conveying slide 8 is connected with an adjustment channel 9, and the adjustment channel 9 is used to flip and adjust the posture of the lamp beads, so that the lamp beads change from the lamp head facing down and the lamp feet facing up to the posture with the lamp feet facing down and the lamp head facing up. A conveying channel 10 is provided on the side of the adjustment channel 9 away from the conveying slide 8. After the posture of the lamp beads is adjusted by the adjustment channel 9, they fall into the conveying channel 10. The bottom of the conveying channel 10 is connected to the packaging belt. After the posture of the lamp beads is adjusted, they fall directly into the packaging belt through the conveying channel 10 for packaging.

[0080] With this arrangement, the lamp beads will fall into the adjustment channel 9 and be automatically adjusted after cutting. This means that there is no need to manually flip the lamp beads one by one after cutting, which can greatly reduce manual work and effectively solve the problem of reduced lamp bead flipping efficiency and accuracy caused by long-term manual work, which is beneficial to ensure the daily processing and production of lamp beads.

[0081] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
