Description

Technical Field

[0001] This invention relates to the field of lighter manufacturing technology, and in particular to an automatic assembly device for lighter igniters. Background Technology

[0002] As a widely used ignition tool in daily life, the production efficiency and quality of lighters are crucial to meeting market demands. In the lighter manufacturing process, the assembly of the igniter is a key step that directly affects the lighter's performance and user experience. However, traditional igniter assembly methods mostly rely on manual operation, which is not only inefficient but also makes it difficult to guarantee assembly precision and consistency.

[0003] Especially during the initial arrangement stage of the igniters, due to various factors in the production process, the igniters are often in a disordered state, requiring manual sorting and arrangement, which greatly restricts the improvement of production efficiency. At the same time, the bending process at the end of the electronic wire of the igniter also faces problems such as complex operation and difficulty in controlling precision. To address these issues, we provide an automatic assembly device for lighter igniters. Summary of the Invention

[0016] The present invention has the following advantages: 1. This invention uses a vibratory feeder to transport disordered igniters in an orderly manner. A rotary conveyor receives the orderly arranged igniters from the vibratory feeder and drives them to the bending station of a bending assembly. The bending assembly bends the electronic wires of the igniters at the bending station of the rotary conveyor. After bending, the rotary conveyor rotates and bends the igniters to the positioning clamping assembly, where they are clamped. A two-axis moving module transfers the igniters clamped by the positioning clamping assembly to the lighter and installs the bent igniters onto the lighter, completing the igniter assembly. The entire process is automated and requires no manual intervention, greatly improving installation efficiency.

[0017] 2. The present invention uses a rotary drive motor to drive a rotary shaft to rotate, thereby moving multiple rotary plates mounted on the rotary shaft to the outlet of the vibratory feeder conveying assembly. Igniters from the vibratory feeder conveying assembly are transferred to the receiving slot, thereby receiving the igniters from the vibratory feeder conveying assembly. In order to prevent the igniters from sliding out of the receiving slot, a stop block is used to block the igniters located in the receiving slot.

[0018] 3. In this invention, the transverse cylinder drives the baffle to move, thereby moving the baffle bar to the outlet of the vibratory feeder conveying assembly to close it, preventing the igniter of the vibratory feeder conveying assembly from continuing to convey when the rotary conveying assembly is rotating. When it is no longer necessary to block it, it is only necessary to restart the transverse cylinder to drive the baffle to move so that the second clearance groove is aligned with the outlet of the vibratory feeder conveying assembly, thereby releasing the closure of the outlet of the vibratory feeder conveying assembly and allowing the igniter in the vibratory feeder conveying assembly to move into the rotary conveying assembly.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] like Figure 1 — Figure 17 The example shown.

[0039] An automatic assembly device for lighter igniters includes a vibratory feeder assembly 1 that transports igniters from a disordered arrangement to an ordered arrangement. A rotary conveyor assembly 2 is located at the outlet of the vibratory feeder assembly 1 to transport the ordered igniters. A mounting frame 3 is located on one side of the rotary conveyor assembly 2. A bending assembly 4 is mounted on the mounting frame 3 to bend the electronic wires of the igniters located in the rotary conveyor assembly 2. A blocking structure 7 for controlling the opening and closing of the outlet of the vibratory feeder assembly 1 is also fixedly mounted on the mounting frame 3. A two-axis moving module 5 is located at one end of the rotary conveyor assembly 2. A positioning clamping assembly 6 is mounted on the moving end of the two-axis moving module 5 to clamp and install the bent igniters located in the rotary conveyor assembly 2.

[0040] See Figure 1 As shown, the vibratory feeder conveyor 1 arranges the randomly arranged igniters into an ordered arrangement, and the rotary conveyor 2 receives the ordered igniters from the vibratory feeder conveyor 1. The rotary conveyor 2 rotates and conveys the igniters to the bending position of the bending component 4. The bending component 4 bends the electronic wire end of the igniter to meet the usage requirements. After bending, the rotary conveyor 2 rotates and conveys the bent igniter to the loading position of the positioning clamping component 6. The two-axis moving module 5 moves the positioning clamping component 6 to the loading position to clamp the bent igniter in the rotary conveyor 2. The two-axis moving module 5 moves the igniter clamped by the positioning clamping component 6 to the position of the lighter and installs the bent igniter onto the lighter, thus completing the installation of the igniter. No manual intervention is required during the loading, transferring, and installation processes; everything is completed automatically, which greatly improves the installation efficiency of the igniter and ensures the quality of the installation.

[0041] It should be noted that the two-axis moving module 5 can realize movement in both the horizontal and vertical directions, and can be assembled from two motor lead screw modules. In other embodiments, the two-axis moving module 5 can also be replaced by a three-axis moving module. The working principle can refer to the principle of realizing three-axis movement of existing three-axis machine tools, which will not be elaborated here.

[0042] The vibratory feeder conveying assembly 1 includes a vibratory feeder body 11 with igniters arranged in an orderly manner. A base frame 12 is provided on one side of the vibratory feeder body 11. A conveying guide rail 13 is installed on the base frame 12. A conveying belt 15 is provided on the bottom surface of the conveying guide rail 13. A conveying motor 14 is fixedly installed on the base frame 12. The power output end of the conveying motor 14 is connected to the power input end of the conveying belt 15.

[0043] See Figure 1 and Figure 2 As shown, the randomly arranged igniters are first arranged in an orderly manner by the vibratory feeder body 11, and then the orderly arranged igniters are transported to the conveyor rail 13. The conveyor motor 14 is started to drive the conveyor belt 15 to rotate, thereby conveying the igniters under the guidance of the conveyor rail 13, and then conveying them to the rotary conveyor assembly 2 through the end of the conveyor rail 13 to realize the feeding of the igniters.

[0044] It should be noted that the upper surface of the conveyor belt 15 contacts the igniter in the conveyor rail 13, thereby enabling the igniter in the conveyor rail 13 to be conveyed. Furthermore, a vibrator can be used to replace the conveyor belt 15 to convey the igniter in the conveyor rail 13. In other words, any structure or component that can convey the igniter in the conveyor rail 13 is acceptable, and no specific restrictions are imposed here.

[0045] The rotary conveying assembly 2 includes a mounting base 21, on which a rotary shaft 23 is rotatably mounted. A rotary drive motor 22 is fixedly mounted on one side of the mounting base 21. The power output end of the rotary drive motor 22 is connected to the power input end of the rotary shaft 23. Multiple evenly distributed rotary plates 24 are fixedly mounted on the outer circumference of the rotary shaft 23. Multiple evenly distributed receiving slots 25 are opened on the rotary plates 24. A first through slot 26 is opened through the rotary plates 24 along the axial direction of the rotary shaft 23, and the first through slot 26 passes through each receiving slot 25. A stop block 27 is installed in the first through slot 26.

[0046] See Figure 1 , Figures 3 to 5As shown, firstly, the rotary drive motor 22 drives the rotary shaft 23 to rotate, which in turn drives the rotary plate 24 to rotate, aligning the various receiving slots 25 on the rotary plate 24 with the outlet of the conveying guide rail 13, thereby receiving the igniters conveyed from the conveying guide rail 13. After the igniters in the conveying guide rail 13 enter the receiving slots 25, the outlet of the conveying guide rail 13 is sealed by the blocking structure 7 to prevent the igniters in the conveying guide rail 13 from continuing to enter the receiving slots 25 and colliding with the igniters in the receiving slots 25. After the igniters enter the receiving slots 25, they are blocked by the stop block 27 on the rotary plate 24 to prevent the igniters in the receiving slots 25 from slipping out of the receiving slots 25 during rotation. Next, the rotary drive motor 22 drives the rotary shaft 23 to rotate, which in turn drives the rotary plate 24. The receiving slot 25 rotates. In this embodiment, the bending component 4 is located above the outlet of the conveying guide rail 13. The rotating shaft 23 rotates the igniter located in the receiving slot 25 to the bending position of the bending component 4. At this time, the receiving slot 25 of the next rotating plate 24 is aligned with the outlet of the conveying guide rail 13, thereby receiving the igniter from the conveying guide rail 13. After the igniter at the bending position of the bending component 4 has its electronic wire bent, the rotating drive motor 22 rotates the igniter in the receiving slot 25 of the next rotating plate 24 to the bending position of the bending component 4. The electronic wire of the igniter is bent by the bending component 4. The igniter after the electronic wire is bent is transferred to the loading position of the positioning clamping component 6, and is clamped by the positioning clamping component 6. This process is repeated continuously, bending and clamping the igniter from the conveying guide rail 13.

[0047] In this embodiment, multiple rotating plates 24 are evenly installed on the outer surface of the rotating shaft 23. The number of rotating plates 24, the angle of rotation of the rotating shaft 23 each time, and the bending position of the bending component 4 can be adaptively installed and adjusted according to actual needs, and no specific restrictions are made here.

[0048] The blocking structure 7 includes a third mounting plate 71 fixedly mounted on the mounting bracket 3. A transverse cylinder 72 is fixedly mounted at the end of the third mounting plate 71. A baffle 73 is fixedly mounted at the output end of the transverse cylinder 72. The baffle 73 has a bent part and a flat part. A second clearance groove 74 adapted to the outlet of the vibratory feeder conveying assembly 1 is provided on the bent part and the flat part. A baffle 75 is formed between two adjacent second clearance grooves 74.

[0049] See Figure 1 , Figure 3 as well as Figure 16As shown, when the igniter in the conveying guide rail 13 enters the receiving groove 25, the transverse cylinder 72 drives the baffle 73 to move, causing the baffle 75 to close the outlet of the conveying guide rail 13, thereby preventing the igniter in the conveying guide rail 13 from continuing to be conveyed into the receiving groove 25 or falling out. After the rotating plate 24 rotates and the empty receiving groove 25 is aligned with the outlet of the conveying guide rail 13, the transverse cylinder 72 drives the baffle 73 to move, causing the baffle 75 to be misaligned with the outlet of the conveying guide rail 13, so that the second clearance groove 74 is aligned and flush with the outlet of the conveying guide rail 13. The igniter from the conveying guide rail 13 passes through the second clearance groove 74 and enters the receiving groove 25, realizing the transfer of the igniter.

[0050] It should be noted that the size of the second clearance groove 74 is the same as the size of the outlet of the conveying guide rail 13, so that the igniter in the conveying guide rail 13 can pass through the second clearance groove 74 and enter the hollow receiving groove 25 in the rotating plate 24 to realize the feeding.

[0051] The bending assembly 4 includes a first mounting plate 41 fixedly mounted on the mounting bracket 3. The first mounting plate 41 is equipped with an abutment structure 42 that abuts against the igniter in the rotary conveying assembly 2. A clamping structure 43 that clamps the electronic wire of the igniter is fixedly mounted on the first mounting plate 41. A bending structure 44 that bends the electronic wire clamped by the clamping structure 43 is installed on the moving end of the abutment structure 42.

[0052] See Figure 3 and Figure 5 As shown, when bending is required, the electronic wire of the igniter is first clamped by the clamping structure 43. The end of the clamped electronic wire is located on the other side of the clamping end. The electronic wire on the other side is the part that needs to be bent. Next, the pressing head of the pressing end of the igniter in the receiving groove 25 at the bending position is abutted by the abutting structure 42. Under the abutting action of the abutting structure 42 and the clamping action of the clamping structure 43, the electronic wire and the igniter are fixed to prevent them from moving. Then, the bending end of the bending structure 44 abuts and bends the part that needs to be bent, thereby completing the bending process of the electronic wire of the igniter.

[0053] The abutment structure 42 includes an abutment cylinder 421 fixedly mounted on the first mounting plate 41. An abutment plate 422 is fixedly mounted on the power output end of the abutment cylinder 421. An abutment joint 423 is provided at the end of the abutment plate 422 to abut against the end of the igniter.

[0054] The clamping structure 43 includes a moving cylinder 431 fixedly mounted on the first mounting plate 41 for lateral movement. A lifting cylinder 432 for lifting is fixedly mounted on the output end of the moving cylinder 431. A first clamping cylinder 433 is fixedly mounted on the output end of the lifting cylinder 432. A first clamping transmission plate 434 and a second clamping transmission plate 435 are respectively mounted on the two clamping ends of the first clamping cylinder 433. The first clamping transmission plate 434 and the second clamping transmission plate 435 are respectively provided with a plurality of first clamping claws 436 and second clamping claws 437. The first clamping cylinder 433 drives the first clamping transmission plate 434 and the second clamping transmission plate 435 to move closer or further away from each other, thereby driving the first clamping claws 436 and the second clamping claws 437 to move closer or further away from each other to achieve clamping or releasing of the electronic wire. A bent contact surface 438 is formed at the bend of the first clamping claws 436 and the second clamping claws 437. The first clamping claw 436 has a second clamping opening 4310 on its side near the second clamping claw 437, and the second clamping claw 437 has a first clamping opening 439 on its side near the first clamping claw 436. The first clamping opening 439 and the second clamping opening 4310 form a clamping hole for clamping the electronic wire.

[0055] The bending structure 44 includes a bending mounting plate 445 disposed on the bottom surface of the abutment plate 422. A bending cylinder 441 is fixedly mounted on the side of the bending mounting plate 445. A bending plate 442 is fixedly mounted on the output end of the bending cylinder 441. A bending head 443 is disposed on the side of the bending plate 442. A guide groove 444 adapted to the electronic wire is opened on the side of the bending head 443 near the bending contact surface 438.

[0056] See Figure 17 As shown, Figure 17 The diagram shows the transition of the electron wire from a straight state to a bent state.

[0057] See Figures 6 to 10The bending process is as follows: First, the linkage of the moving cylinder 431 and the lifting cylinder 432 positions the second clamping claw 437 and the first clamping claw 436 on both sides of the electronic wire. Then, the first clamping cylinder 433 is activated to clamp the electronic wire located between the second clamping claw 437 and the first clamping claw 436. The bending contact surface 438 at the position of the first clamping claw 436 and the second clamping claw 437, together with the first clamping transmission plate 434 and the second clamping transmission plate 435, forms a bending space. The end of the clamped electronic wire is located in the bending space at the position of the bending contact surface 438. Therefore, the part to be bent is located in the bending space between the first clamping claw 436 and the second clamping claw 437. The part of the electronic wire located in the bending space is the part to be bent. After clamping is completed, the abutment cylinder 421 drives the abutment plate 422 to move towards the igniter, thereby causing the abutment 423 to engage with the igniter. The pressing head makes contact to achieve abutment. In the state where the first clamping claw 436 and the second clamping claw 437 clamp the electronic wire and the abutting head 423 abuts the pressing head, the electronic wire is fixed. When the abutting plate 422 moves, it also drives the bending structure 44 to move, so that the bending structure 44 can reach the predetermined bending position. At this time, the bending head 443 is located below the bending space. When bending, the bending cylinder 441 drives the bending plate 442 to rise, so that the side of the bending head 443 is close to the bending contact surface 438 to bend the part of the electronic wire that needs to be bent in the bending space. After the bending is completed, the abutting cylinder 421, the moving cylinder 431, the lifting cylinder 432, the first clamping cylinder 433, the bending cylinder 441, etc., return to the initial state, that is, the igniter is not clamped or abutted, and the bending process of the igniter in the receiving groove 25 at the bending position is completed.

[0058] It should be noted that, in order to prevent the insulation layer on the surface of the electronic wire from being damaged during clamping and bending, a clearance space is formed by the first clamp 439 and the second clamp 4310 to allow for clearance. Of course, to ensure the clamping of the electronic wire, the clearance space formed by the first clamp 439 and the second clamp 4310 can be smaller than the diameter of the electronic wire, thereby ensuring the clamping of the electronic wire. In order to prevent the insulation layer of the electronic wire from being squeezed and worn during bending, a guide groove 444 adapted to the electronic wire is opened on the side of the bending head 443, thereby avoiding the squeezing and damage to the electronic insulation layer during bending.

[0059] In this embodiment, the first gripper 436 and the second gripper 437 are the same size and shape, both being "L" shaped.

[0060] The positioning and clamping assembly 6 includes a fixed plate 61 fixedly installed on the moving end of the two-axis moving module 5. A second clamping cylinder 62 is fixedly installed on the fixed plate 61. A gripper structure 63 is installed on the clamping end of the second clamping cylinder 62. The gripper structure 63 includes a first connecting block 631 and a second connecting block 633 installed on the two clamping ends of the second clamping cylinder 62. A plurality of first chucks 632 are provided at the bottom of the first connecting block 631. A plurality of grooves 636 are provided on the second connecting block 633. A mounting shaft 637 is provided in each groove 636. A transmission rod 634 is hinged to the outer surface of the mounting shaft 637. A second chuck 635 is provided at the bottom of each transmission rod 634. A compression spring 638 is provided in each groove 636. The compression spring 638 is located between the inner wall of the groove 636 and the transmission rod 634. A first pressure plate 6310 is provided on the upper surface of the second connecting block 633 to close the groove 636.

[0061] See Figure 11 and Figure 12 As shown, when clamping the bent igniter, the two-axis moving module 5 drives the fixed plate 61 to move, so that the gripper structure 63 moves to the position of the bent igniter. The second clamping cylinder 62 is activated to drive the first connecting block 631 and the second connecting block 633 to move, so that the first clamp 632 and the second clamp 635 at their ends move closer to each other, clamping the igniter between the first clamp 632 and the second clamp 635.

[0062] To prevent the second chuck 635 and the first chuck 632 from damaging the igniter located between them, a compression spring 638 is used to buffer the clamping of the second chuck 635 and the first chuck 632, allowing the transmission rod 634 to slide on the surface of the mounting shaft 637, thereby preventing damage to the igniter. In order to provide sufficient buffer space, the mounting space of the groove 636 is larger than the width of the transmission rod 634, providing the distance required for the transmission rod 634 to drive the second chuck 635 to move.

[0063] A disassembly and assembly structure 639 for fixing the mounting shaft 637 is provided between the mounting shaft 637 and the second connecting block 633. The disassembly and assembly structure 639 includes a mounting groove 6391 that passes through the second connecting block 633, a slot 6392 that is provided on the outer surface of the mounting shaft 637, and a connecting hole that communicates with the mounting groove 6391 that is provided on the inner wall of the groove 636. When the mounting shaft 637 is installed into the connecting hole, a locking rod 6393 is installed in the mounting groove 6391. At this time, the locking rod 6393 is engaged in each slot 6392 to fix the mounting shaft 637.

[0064] See Figure 12As shown, when installing and fixing the mounting shaft 637, first insert the mounting shaft 637 into the connecting hole. Each connecting hole is connected to the mounting groove 6391. At this time, the retaining groove 6392 is located at the position of the mounting groove 6391. Insert the retaining rod 6393 into the mounting groove 6391 and also into the retaining groove 6392, engaging with the retaining groove 6392. Since the retaining rod 6393 is located in the mounting groove 6391 and also engaged with the retaining groove 6392, the mounting shaft 637 cannot be detached from the connecting hole, thus realizing the installation of the mounting shaft 637.

[0065] A clearance block 6311 connected by an extension plate is installed on the fixed plate 61. The bottom surface of the clearance block 6311 is provided with a first clearance groove 6312 that is adapted to the bent electronic wire.

[0066] See Figure 13 and Figure 14 As shown, in order to prevent the first chuck 632 and the second chuck 635 from touching the electronic wire during the clamping process of the igniter and causing the electronic wire to tilt or shift, the electronic wire enters the first clearance groove 6312 during the clamping process to achieve clearance.

[0067] The second clamping cylinder 62 has a positioning and pressing structure 64 on one side for positioning the igniter during installation. The positioning and pressing structure 64 includes a second mounting plate 641 fixedly installed on the side of the second clamping cylinder 62. A sliding plate 642 is slidably installed on the side of the second mounting plate 641. A tension spring 643 is hung between the sliding plate 642 and the second mounting plate 641. A pressure block 644 is fixedly installed at the bottom of the sliding plate 642. A sealing plate 646 is fixedly installed on the side of the pressure block 644. An installation hole 645 is formed between the pressure block 644 and the sealing plate 646. A positioning protrusion 6410 for positioning the lighter is integrally provided on the bottom surface of the sealing plate 646. A pin 647 for pressing down the lighter housing is provided in the installation hole 645. A connecting plate 648 is provided on the top surface of the pin 647. A second pressure plate 649 for sealing the installation hole 645 is fixedly installed on the upper surface of the installation hole 645.

[0068] See Figure 15As shown, when installing the bent igniter, the two-axis moving module 5 drives the gripper structure 63 and the positioning pressing structure 64 to descend, causing the positioning protrusion 6410 to be inserted into the positioning position in the lighter. At this time, the bottom of the pin 647 contacts the lighter housing frame. As the second mounting plate 641 continues to descend, the connecting plate 648 retracts and the tension spring 643 extends. The sliding plate 642 drives the pressure block 644 and the sealing plate 646 to slide on the second mounting plate 641. At this time, the igniter held by the first clamp 632 and the second clamp 635 enters the predetermined installation position. The bottom surfaces of the first clamp 632 and the second clamp 635 abut against the pressing surface of the igniter, so as to facilitate pressing the igniter into the predetermined position during descent, thereby realizing the installation of the igniter. After the installation is completed, the gripper structure 63 and the positioning pressing structure 64 mentioned above return to the initial position, waiting for the installation of the next set of igniters.

[0069] The working process of this invention is as follows: First, the vibratory feeder conveying assembly 1 arranges the disordered igniters in an orderly manner and conveys them to the rotary conveying assembly 2. The igniters located on the rotary conveying assembly 2 are conveyed to the bending position of the bending assembly 4. Next, the clamping structure 43 in the bending assembly 4 clamps the electronic wire. After clamping, the abutment structure 42 abuts against the igniter to prevent the electronic wire from moving during the subsequent bending process. The bending structure 44 bends the electronic wire clamped by the clamping structure 43. After bending, the rotary conveying assembly 2 conveys the bent igniter to the unloading position, that is, the positioning clamping assembly 6. At the loading position, the two-axis moving module 5 moves the positioning and clamping assembly 6 to the loading position. Then, the second clamping cylinder 62 in the positioning and clamping assembly 6 drives the gripper structure 63 to clamp the igniter. The two-axis moving module 5 then moves the clamped igniter to the lighter position. During the downward movement of the igniter held by the gripper structure 63, the two-axis moving module 5 also drives the positioning and pressing structure 64 to move downward. The positioning and pressing structure 64 limits and fixes the lighter to prevent the lighter from moving. Then, during the continued downward movement, the clamped igniter is pressed and installed into the lighter, realizing the automatic installation of the igniter.
