Description

Technical Field

[0001] This invention relates to the field of light bulb assembly technology, and more particularly to a double-wire insertion mechanism for light panels, an insertion module, and an insertion machine. Background Technology

[0002] Household light bulbs generally include incandescent bulbs and LED bulbs. These bulbs typically have two interfaces on their bulb boards (PCBs or bases), so a total of two wires need to be plugged in during assembly.

[0003] Current automatic light bulb insertion machines typically insert only one wire at a time. For example, a wire insertion mechanism disclosed in Chinese utility model patent CN220628466U requires two repeated insertion actions. However, in actual assembly and production, due to the small size of the light board and the small distance between the two insertion holes (generally 1.5-10mm), and the relatively thin diameter of the wires (generally 0.5-2.5mm), the repeated insertion can easily cause collisions with already inserted wires, resulting in the bending of the relatively soft wires and affecting subsequent welding, assembly, and other processes.

[0004] Some manufacturers have also launched automatic wire insertion machines that can carry two wires at once, but they simply combine two traditional split-type wire clamps (or wire pliers) into one wire insertion drive module (Z-axis movement, aligned with the wire insertion direction). The opening and closing actions are controlled separately when inserting the wire, which is still a two-step wire insertion action. The wire insertion efficiency is insufficient, and the overall size of the machine is relatively large.

[0005] If two wire holes are directly set on the existing single wire clamp, two wires can be inserted at once without mechanical travel interference or excessive size. However, when the same clamping force is applied to two wires with different deviation tolerances, the clamping force on the wires cannot be unified. The closed-loop clamping force control system based on pressure sensor cannot control the clamping force of the two wires separately, which will eventually lead to inconsistent insertion depth of the two wires. In severe cases, only one wire can be inserted, and the adaptability is also limited.

[0006] Therefore, in order to improve the automation level and efficiency of the lamp board wiring machine, this application proposes a lamp board double-wire wiring mechanism, wiring module and wiring machine that have no mechanical stroke interference, high wiring consistency and small overall size, which greatly improves adaptability and wiring efficiency. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-wire insertion mechanism, insertion module, and insertion machine for lamp panels. This mechanism combines the mobility of existing single-wire clamp single-hole solutions with the high efficiency of single-wire clamp dual-hole solutions. It eliminates the mechanical travel interference and insufficient insertion depth consistency of both solutions, as well as the need to bend the longer wire. It is more adaptable and reliable, and has a simple overall structure. The cost of directly modifying existing insertion machines is relatively low. Its adaptability is particularly significant for lamp insertion assembly machines with small size and high insertion accuracy requirements.

[0008] Firstly, in order to achieve the above objectives, the present invention provides the following technical solution: The lamp board dual-wire insertion mechanism includes a first wire clamp and a second wire clamp, both of which are mounted on the insertion drive module. The first wire clamp and the second wire clamp can move independently in the direction perpendicular to the insertion. The free ends of the first wire clamp and the second wire clamp are provided with wire grooves aligned with the insertion direction. When the first wire clamp and the second wire clamp are brought together, each wire groove forms two insertion holes. Both free ends of the second wire clamp are L-shaped. The distance between the handles of the two free ends of the second wire clamp is greater than the total width of the free ends of the two first clamps. When the two free ends of the second wire clamp are brought together, they can surround the free ends of the two first clamps.

[0009] This implementation provides a structure that combines the mobility of existing single-wire clamp single-socket solutions with the efficiency of single-wire clamp double-socket solutions. It also eliminates the drawbacks of mechanical travel interference and insufficient insertion depth consistency of the two solutions, as well as the need to bend the longer wire. It is more stable and reliable in adaptability, and the overall structure is simple. It is low-cost to directly modify existing wiring machines. Its adaptability is particularly obvious for bulb wiring assembly machines with small size and high wiring accuracy requirements.

[0010] In conjunction with the first aspect, in one embodiment, the first clamp includes two first clamping plates, and the second clamp includes two second clamping plates. The free ends of the two first clamping plates facing each other are provided with first wire grooves, and the free ends of the two second clamping plates facing each other are provided with second wire grooves. When the first clamps are brought together, the two first wire grooves form a first insertion hole, and when the second clamps are brought together, the two second wire grooves form a second insertion hole. The ends of both the first and second insertion holes away from the insertion direction are U-shaped, V-shaped, or trumpet-shaped.

[0011] By adopting this implementation method and setting a guide structure at the inlet of the online slot, the failure rate caused by wire deviation during the wire threading process is significantly reduced, and the wire insertion success rate is improved. It is especially suitable for scenarios with strict requirements on cycle time and yield in high-speed automated production lines.

[0012] In conjunction with the first aspect, in one embodiment, the end faces of the first clamp and the second clamp facing the insertion direction are flush.

[0013] This implementation method eliminates the need for additional sensor feedback or complex travel compensation algorithms, ensuring consistent insertion depth for dual-wire connections and is suitable for most lamp board wiring processes.

[0014] In conjunction with the first aspect, in one embodiment, the opening and closing motion of the first clamp and the second clamp includes at least one of oscillating and translational motions. It also includes a first split-and-join drive module and a second split-and-join drive module. The first split-and-join drive module and the second split-and-join drive module include at least one of a finger cylinder, an electromagnet, and a motor. The first wire is clamped on the output end of the first split-and-join drive module, and the second wire is clamped on the output end of the second split-and-join drive module.

[0015] This implementation provides multiple independent driving methods for the two wire clamps, offering flexible options for wiring scenarios with different precision and cost requirements.

[0016] In conjunction with the first aspect, in one embodiment, both the first split-and-join drive module and the second split-and-join drive module are translational finger cylinders, the two first clamping plates are respectively fixedly connected to the two pneumatic grippers of the first split-and-join drive module, and the two second clamping plates are respectively fixedly connected to the two pneumatic grippers of the second split-and-join drive module. It also includes a bracket for connecting the output end of the plug-in drive module. The first split-and-join drive module and the second split-and-join drive module are both fixedly connected to the bracket. The split-and-join movement stroke of the second split-and-join drive module is not less than the split-and-join movement stroke of the first split-and-join drive module, and the split-and-join movement of the second split-and-join drive module is not later than the split-and-join movement of the first split-and-join drive module.

[0017] By adopting this implementation method, the nested structure is extended from static design to dynamic operation through dual constraints of stroke and timing, ensuring the reliability of the mechanism in high-speed reciprocating motion.

[0018] In conjunction with the first aspect, in one embodiment, the second split-opening drive module is threadedly connected to the bracket and located at the free end of the first clamping plate facing upward.

[0019] This implementation method employs a more compact layout of split-and-combine drive modules, further reducing the overall size and improving integration while maintaining the nested dual-clip functionality.

[0020] In conjunction with the first aspect, in one embodiment, a wiring module is further included on the output end of the wiring drive module, the bracket is fixedly connected to the output end of the wiring module, the wiring module includes at least one of a cylinder and a linear motor, and the stroke direction of the wiring module is parallel to or aligned with the wiring direction.

[0021] This implementation method ensures both insertion speed and accuracy, and improves insertion yield.

[0022] In conjunction with the first aspect, in one embodiment, the minimum distance d1 between the first insertion hole and the outer end face of the free end of the first clamping plate, and the minimum distance d2 between the second wire groove and the inner end face of the free end of the second clamping plate are: 0.1≤d1, d2≤9.4mm, and 0.2mm≤d1+d2≤9.5mm; when the first clamping plate and the second clamping plate are close together, the minimum gap d3 between the free end of the first clamping plate and the free end of the second clamping plate is: 0≤d3≤9.3mm.

[0023] This implementation provides a wiring assembly mechanism that can cover everything from miniature PCB indicator lights to high-power lamp boards, and is particularly suitable for wiring scenarios with narrow spaces and small spacing.

[0024] In conjunction with the first aspect, in one embodiment, the minimum distance d1 between the first insertion hole and the outer end face of the free end of the first clamping plate, and the minimum distance d2 between the second wire groove and the inner end face of the free end of the second clamping plate are: 0.5mm≤d1=d2≤4mm; when the first clamping plate and the second clamping plate are close together, the minimum gap d3 between the free end of the first clamping plate and the free end of the second clamping plate is: 0.5mm≤d3≤1mm.

[0025] This implementation provides a wire clamp solution that is more suitable for assembling the wiring of mainstream light bulb products.

[0026] Secondly, in order to achieve the above objectives, the present invention also provides the following technical solution: The lamp panel wiring module includes a wiring mechanism as described in the first aspect, and a wiring drive module, wherein the wiring drive module includes at least one of a linear guide rail and a lead screw motor, and further includes: The wire feeding mechanism includes a wire separating wheel set and a drive wheel set. The wire separating wheel set is used to separate the wires, and the drive wheel set is used to drive the wires to move in the insertion direction and is located in the wire output direction of the wire separating wheel set. The wire cutting mechanism includes a fourth split-and-joint drive module located in the wire output direction of the drive wheel assembly and a wire cutting part disposed on the output end of the fourth split-and-joint drive module. The fourth split-and-joint drive module includes at least one of a finger cylinder, a lead screw sleeve mechanism, a linear motor, and a reciprocating swing mechanism. The guide wheel assembly has at least two guide grooves on the axial side wall of each guide wheel for accommodating a single guide wire, and each of the two wire cutting sections has at least two cutting edges at their opposing ends; the arrangement direction of the cutting edges on the wire cutting section, the axial direction of the drive wheel assembly, and the arrangement direction of the two insertion holes are aligned or parallel to each other.

[0027] In conjunction with the second aspect, in one embodiment, a third clamp is also included. The third clamp includes a third split-opening drive module and two third clamping plates disposed on the output end of the third split-opening drive module. The free ends of the two third clamping plates are L-shaped relative to each other, and the distance between the handles of the two free ends of the third clamp is greater than the total width of the free ends of the two second clamping plates. When the two free ends of the third clamp are brought together, they can surround the free ends of the two second clamping plates. The free ends of the two third clamps are provided with third wire grooves on their facing surfaces. When the third clamps come together, the two third wire grooves form a third insertion hole.

[0028] This implementation provides a complete wiring fixture for automatic wiring of light panels, which is suitable for situations where two or more wires need to be assembled, and has greater adaptability.

[0029] In conjunction with the second aspect, in one embodiment, the dividing wheel assembly includes two rows of freely rotatable guide wheels, each guide wheel having parallel axes and each guide groove being axially aligned. The two rows of guide wheels are connected by an elastic element, and the elastic element has a force that pulls the two rows of guide wheels together in the initial state.

[0030] In conjunction with the second aspect, in one embodiment, the drive wheel assembly includes two rollers, the shafts of the two rollers are connected together by a timing belt or timing gear, and are driven by a motor or a rotary cylinder.

[0031] By adopting this implementation method, the elastic floating clamp design automatically adapts to the tolerance differences of the wire diameter, ensuring the synchronization, straightening effect and positioning accuracy of multiple wires during the transmission process.

[0032] In conjunction with the second aspect, in one embodiment, the wire-cutting mechanism further includes a connecting plate, two connecting plates are respectively fixedly connected to the two output ends of the fourth split-and-comb drive module, two wire-cutting parts are provided at the opposite ends of the connecting plates, and two sets of wire-cutting parts are provided along the wire insertion direction.

[0033] This implementation method integrates wire stripping and wire cutting functions into the same mechanism, eliminating the need for a separate wire stripping station, simplifying equipment layout, and improving automation.

[0034] In conjunction with the second aspect, in one embodiment, the cutting edges are all V-shaped or arc-shaped, the cutting portion is plate-shaped, the lateral width of each cutting edge gradually changes along the insertion direction, and the tapering directions of the two cutting portions in the same group are opposite. The two cutting portions in the same group located on the two surfaces with the smallest cutting edge width can overlap in the insertion direction.

[0035] By adopting this implementation method, automatic guidance and progressive shearing are achieved through the geometric design of the cutting edge, which improves the shearing reliability and cross-sectional quality, while extending the service life of the cutting edge.

[0036] Thirdly, in order to achieve the above objectives, the present invention also provides the following technical solution: The lamp panel wiring machine includes a wiring module as described in the second aspect, and a feeding module for conveying lamp panels, the feeding module comprising: A fixture for placing the lamp panel, the fixture including one of a guide rail and a conveyor belt; A feeding drive module is used to drive the lamp board or fixture to move. The feeding drive module includes one of a push plate mechanism and a motor. When the lamp board is placed on the fixture, the interfaces on the lamp board are aligned or parallel to the wiring direction.

[0037] This implementation method enables automated production from lamp board feeding to wire insertion.

[0038] In conjunction with the third aspect, in one embodiment, the fixture includes two mutually spaced tracks, and each of the two tracks has a limiting groove extending through the length of the guide rail on its facing surfaces. The feeding drive module is a push plate mechanism, which includes a push plate drive unit and a push block disposed on the output end of the push plate drive unit. The push plate drive unit includes one of a cylinder and a linear motor.

[0039] This implementation provides a low-cost, high-reliability intermittent feeding solution suitable for intermittent wiring assembly mechanisms.

[0040] In conjunction with the third aspect, in one embodiment, a spacing adjustment mechanism is further provided between the two tracks, the travel direction of which is perpendicular to the length direction of the track.

[0041] This implementation method allows the same equipment to adapt to various specifications of lamp boards, reducing changeover time and improving the flexibility and utilization of the equipment.

[0042] In conjunction with the third aspect, in one embodiment, a mounting frame is further included, on which the wire insertion drive module, wire feeding mechanism, and wire cutting mechanism are all fixedly connected; it also includes: The alignment adjustment mechanism includes one of a linear motor, a cylinder, and a lead screw and sleeve mechanism. The mounting bracket is fixedly connected to the output end of the alignment adjustment mechanism, and the stroke direction of the alignment adjustment mechanism is parallel to the conveying direction of the feeding module.

[0043] This implementation method further ensures the yield rate of wire assembly.

[0044] Compared with the prior art, the beneficial effects of this invention are as follows: It provides a structure that combines the mobility of the existing single-wire clamp single-socket scheme with the high efficiency of the single-wire clamp double-socket scheme. At the same time, it eliminates the disadvantages of mechanical stroke interference and insufficient insertion depth consistency of the two schemes, or the disadvantage of needing to bend the longer wire. It is more stable and reliable in adaptability, and the overall structure is simple. The cost of directly modifying existing wiring machines is low. It has particularly obvious advantages in adapting to bulb wiring assembly machines with small size and high wiring accuracy requirements. Attached Figure Description

[0047] Currently, in the field of automatic bulb assembly equipment, the automatic wire insertion station is usually equipped with a single wire clamp as a tool, which is used in conjunction with the XYZ module or a robot to achieve continuous wire insertion on the bulb board A.

[0048] Since most light bulbs currently have two wires B, such as incandescent bulbs and LED bulbs, etc. Figure 1 As shown, the lamp board A has two interfaces A1, so the single wire clamp method is not efficient enough. Moreover, when inserting a wire a second time on the same lamp board A, it is easy to collide with the first inserted wire B. The small size of the lamp board A is also difficult to position, so there is also the problem of difficulty in cyclic wire insertion.

[0049] If two insertion holes are directly replaced on a single wire clamp, although collisions will no longer occur and the yield rate will be higher, if the two wires B have inconsistent wire diameter deviations or inconsistent surface material properties, then the forces on the two wires B in the two insertion holes will be inconsistent. Therefore, the friction force borne by the wires B during insertion will also be inconsistent, and the final insertion depth cannot be uniform. The problem of insufficient insertion consistency has not been effectively improved, and the adaptability is insufficient.

[0050] In response, some manufacturers have introduced dual-clamp solutions that can carry two wires B at once. However, since this only increases the number of clamps, the two clamps are controlled independently during insertion, requiring two steps to complete the insertion operation. This has not significantly improved efficiency and still results in collision issues. The fundamental reason why dual-clamp solutions can only be controlled independently is that the spacing between the two wires B on the light board A is relatively small, typically only 1.5-10mm. Therefore, if the two clamps are controlled simultaneously, they will inevitably collide in the lateral space. If they are misaligned in the insertion depth direction (Z-axis), the requirement for consistent insertion depth cannot be guaranteed.

[0051] They also tried to arrange the free ends of the two wire clamps symmetrically and force them to insert wires simultaneously. Although this solved the problem of mechanical stroke interference, the overall size of the machine was too large. The layout of other mature standardized equipment such as vision inspection and wire feeding modules needed to be significantly adjusted or the structure redesigned, so its adaptability was also insufficient.

[0052] It should be understood that the following embodiments are all intended to provide a dual-wire wiring solution that combines no mechanical travel interference, high wiring consistency, and small overall size, so as to facilitate those skilled in the art to understand the present invention, rather than to limit the scope of protection of the present invention. All new solutions obtained based on the concept of the present invention through simple modifications or equivalent substitutions should fall within the scope of protection of the present invention.

[0053] The opening and closing movements of the first wire clamp 100 and the second wire clamp 200 should be considered as scissor-like (oscillating) and translational movements in existing wire clamp solutions. The wire groove and insertion hole are positions used to carry the wire B, and their specific shape is usually cylindrical, but other shapes are also possible. The free ends of each wire clamp typically refer to the grippers connected to the opening and closing drive module. It should be noted that the "independent opening and closing movement" mentioned in this solution means that the opening and closing actions of the first wire clamp 100 and the second wire clamp 200 are controlled separately by their respective opening and closing drive modules, without mutual linkage. Therefore, independent adjustment of the clamping force on the two wires B can be achieved to eliminate the problem of uneven clamping force caused by tolerance differences in wire B. The "lamp board A" includes, but is not limited to, incandescent lamp board A, LED lamp board A, indicator light PCB board, etc. The spacing of the insertion holes of different lamp boards A is usually in the range of 1.5-10mm, and the wire diameter of wire B is usually in the range of 0.5-2.5mm. This solution is particularly suitable for such narrow space insertion scenarios with small spacing and small wire diameter.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1: Please see Figure 1-10 The present invention provides the following technical solution: a double-wire insertion mechanism for a lamp board, including a first wire clamp 100 and a second wire clamp 200 both disposed on the insertion drive module 300. The first wire clamp 100 and the second wire clamp 200 can be independently separated and moved along the direction perpendicular to the insertion. The end faces of the free ends of the first wire clamp 100 and the second wire clamp 200 are provided with wire grooves aligned with the insertion direction. When the first wire clamp 100 and the second wire clamp 200 approach each other, each wire groove forms two insertion holes. Both free ends of the second wire clamp 200 are L-shaped. The distance between the handles of the two free ends of the second wire clamp 200 is greater than the total width of the free ends of the two first clamps 101. When the two free ends of the second wire clamp 200 are brought together, they can surround the free ends of the two first clamps 101.

[0056] As an optional implementation of the present invention, during wire insertion, the two free ends of the second wire clamp 200 and the first wire clamp 100 separate simultaneously or sequentially, causing the insertion holes on the two wire clamps to separate. Subsequently, the first wire clamp 100 and the second wire clamp 200 are driven by the wire insertion drive module 300 to move synchronously to the wire outlet end of the wire feeding station in the opposite direction of the wire insertion direction. The wire groove formed after the two insertion holes separate is laterally aligned with the radial direction of the two wires B. Then, the first wire clamp 100 and the second wire clamp 200 simultaneously or sequentially close together. At this point, the two wire slots are joined together, so that the two wires B are clamped in the two wire holes respectively. The wire insertion drive module 300 drives the first wire clamp 100 and the second wire clamp 200 to move synchronously towards the lamp board A along the wire insertion direction. During the movement, the external wire cutting mechanism 500 is activated to cut the wire. At this time, the two wires B can be inserted into the corresponding wire holes of the lamp board A simultaneously under the drive of the wire insertion drive module 300. After the wire insertion is completed, the first wire clamp 100 and the second wire clamp 200 release the wires B synchronously and retract to reset, waiting for the next wire insertion operation.

[0057] During this process, since the insertion hole on the second wire clamp 200 is located on the facing surface of its L-shaped free end, and the insertion hole on the first wire clamp 100 is located on the facing surface of its free end, the two insertion holes are only separated by the gap between the ends of the two wire clamps, so the distance between the two insertion holes is very small. Since the stroke space and direction of the opening and closing motions of the first wire clamp 100 and the second wire clamp 200 are similar or the same, they can move synchronously or sequentially. Therefore, there is no possibility of interference between the movement strokes of the first wire clamp 100 and the second wire clamp 200, and there is no possibility of collision with the wire B during the opening and closing motion. It is also important to note that during the opening and closing motion, the free end of the second wire clamp 200, which is the location of the insertion hole, can laterally surround the free end of the first wire clamp 100. This means that the direction of the power source for the opening and closing motion of the first wire clamp 100 and the second wire clamp 200, as well as the length direction of the free ends of the two clamps, are consistent; that is, the free ends of the two clamps are side-by-side. This differs from the symmetrical double wire clamp design. Not only is the distance between the two insertion holes very close, but because the volume occupied by the other clamp, located in the direction of the free end of one clamp, is allocated to the rear and side ends of that clamp, its free end extension direction does not occupy any space. This makes it easier to apply in the narrow wire feeding and insertion space of small-sized wiring processes, such as those in lamp board A. Therefore, this embodiment possesses both the mobility of a small-sized single wire clamp and the high efficiency of a single wire clamp with two insertion holes, which can simultaneously complete the insertion of two wires B in one insertion action. Furthermore, because the two insertion holes are not on the same wire clamp, they can be independently controlled by the clamping force negative feedback of the pressure sensor, thereby eliminating the deviation tolerance of different wires B and overcoming the disadvantage of insufficient insertion depth consistency in the single wire clamp with two insertion holes, thus significantly enhancing its adaptability.

[0058] In this embodiment, since the basic design purpose of the wire clamps in the prior art is to clamp the wire B, the opening and closing movements of the two wire clamps in this embodiment are essentially within the same plane perpendicular to the insertion direction. Considering the L-shape of the free end of the second wire clamp 200 and its ability to surround the free end of the first wire clamp 100 when closed, the positional relationship of the two wire clamps in the closed state can be understood as follows: the L-shaped end of the second wire clamp 200 can at least cover the free end face of the first wire clamp 100. Thus, it can be concluded that the two insertion holes are distributed at the covered area of ​​the second wire clamp 200 and the covered area of ​​the first wire clamp 100, thereby forming a clamping structure with a small spacing between the wires B. It cannot be understood as only covering the surface of the free end of the first wire clamp 100 in the insertion direction or the side surface along the opening and closing direction.

[0059] It should be noted that the specific positions of the two plug holes on the two clamps can be aligned along the length of the clamps or misaligned, depending on the specific distribution direction and spacing of the interfaces A1 on the lamp board A to be plugged in. Therefore, this embodiment does not make a specific limitation on this. Of course, it is preferable that the two plug holes are aligned along the direction of the free end of the clamp, that is, the facing surfaces are continuous when the two clamps are closed. For the free ends of the two wire clamps, a straight plate-like or rod-like structure is usually chosen, but a curved type is not affected by the actual use. The facing surfaces of the two wire clamps can also be planar or curved, as long as the wire groove can be combined into a complete wire insertion hole that is aligned / parallel to the wire insertion direction when the two facing surfaces are merged. Therefore, this embodiment does not make specific limitations in this regard. The opening and closing motion of the two wire clamps can be either swinging (rotational opening and closing, such as scissor-like) or translational (the two halves of the free end of each wire clamp separate and come together relatively parallel). As long as the closing motion of the first wire clamp 100 is not later than the second wire clamp 200, and the separating motion of the first wire clamp 100 is not earlier than the first wire clamp 200, it can be completed. Therefore, this embodiment does not specifically limit the specific form of the opening and closing motion. For the two wire clamps, the free ends facing the insertion direction (e.g.) Figure 3 and Figure 9 As shown, the bottom surfaces of the ends of the first clamping plate 101 and the second clamping plate 201 can be flush, which is applicable to most cases, but they can also be uneven, depending on whether the lamp plate A has a built-in irregular or foolproof positioning structure. Therefore, this embodiment does not make specific limitations on this. Regarding the insertion direction, since insertion is typically performed on a flat lamp panel A, the insertion direction is usually perpendicular to the horizontal plane and downwards. However, in some possible application scenarios, those skilled in the art may design the feeding module 700 to transport the lamp panel A in a non-horizontal position, such as a vertical conveyor. In this case, the insertion direction can be parallel to the horizontal plane. Alternatively, if the lamp panel A feeding module 700 is located above the insertion mechanism, the insertion direction can also be parallel to the horizontal plane and upwards. Furthermore, the interface A1 on some lamp panel A products may not be perpendicular to the plane of the lamp panel A, such as an angled interface A1. In this case, the insertion direction should be angled. Therefore, the insertion direction should depend on the final orientation of the interface A1 and is not always perpendicular to the plane of the lamp panel A or perpendicular to the horizontal plane.

[0060] This implementation provides a structure that combines the mobility of existing single-wire clamp single-socket solutions with the efficiency of single-wire clamp double-socket solutions. It also eliminates the drawbacks of mechanical travel interference and insufficient insertion depth consistency of the two solutions, as well as the need to bend the longer wire. It is more stable and reliable in adaptability, and the overall structure is simple. It is low-cost to directly modify existing wiring machines. Its adaptability is particularly obvious for bulb wiring assembly machines with small size and high wiring accuracy requirements.

[0061] In some possible embodiments, such as Figure 2-4 As shown, the first wire clamp 100 includes two first clamping plates 101, and the second wire clamp 200 includes two second clamping plates 201. The free ends of the two first clamping plates 101 facing each other are provided with first wire grooves 102, and the free ends of the two second clamping plates 201 facing each other are provided with second wire grooves 202. When the first wire clamp 100 is brought together, the two first wire grooves 102 form a first insertion hole 103, and when the second wire clamp 200 is brought together, the two second wire grooves 202 form a second insertion hole 203. The ends of the first insertion hole 103 and the second insertion hole 203 away from the insertion direction are both U-shaped, V-shaped, or trumpet-shaped.

[0062] As an optional implementation of this invention, the U-shaped, V-shaped, or trumpet-shaped opening serves as a guide during wire feeding. It should be noted that in actual automated wire insertion processes, when wire B is fed to the clamp position by the wire feeding mechanism 400, due to the flexibility of wire B itself and the mechanical tolerances of the wire feeding mechanism 400, the end of wire B may experience a slight positional offset. If the entrance to the insertion hole is straight, the offset end of wire B may easily press against the end face of the insertion hole and fail to enter smoothly, resulting in wire insertion failure. However, by designing the end of the insertion hole away from the insertion direction as U-shaped, V-shaped, or trumpet-shaped, a gradually narrowing guide opening is formed, allowing wire B to slide into the hole along the inclined surface even with slight offset.

[0063] Specifically, the U-shaped opening has a rounded cross-section with an inlet diameter approximately 1.5-2 times the diameter of the insertion hole, making it suitable for scenarios with significant wire B offset. The V-shaped opening is formed by the intersection of two inclined planes, with a guiding angle typically between 30° and 60°, resulting in a more compact structure. The trumpet-shaped opening has a tapered, gradually expanding cross-section, offering the largest inlet area and the most significant guiding effect. Those skilled in the art can flexibly choose the opening shape based on the precision of the wire feeding mechanism 400 and the flexibility of the wire B.

[0064] By adopting this implementation method and setting a guiding structure at the inlet of the online slot, the failure rate caused by the deviation of the wire B during the wire threading process is significantly reduced, and the wire insertion success rate is improved. It is especially suitable for high-speed automated production lines with strict requirements for cycle time and yield.

[0065] In some possible embodiments, such as Figure 9 As shown, the end faces of the first clamping plate 101 and the second clamping plate 201 facing the insertion direction are flush.

[0066] As an optional implementation of the present invention, although the lamp plate A in some bulb products has an irregular positioning structure or a foolproof design, so the end faces of the two clamps may not be flush to adapt to the steps or uneven structure on the surface of the lamp plate A, the lamp plate A of most bulb products is a flat surface during the wire insertion process. Therefore, in order to ensure consistent insertion depth, the two clamps must not have a height difference during wire insertion.

[0067] It should be noted that the consistency of the insertion depth of the two wires B during the simultaneous insertion of the two wires B into the lamp board A is a key indicator of the insertion quality. If there is a height difference between the end faces of the two clamping plates in the insertion direction, when the insertion drive module 300 moves the entire mechanism towards the lamp board A, the two insertion holes will reach the surface of the lamp board A at different times, or one may touch the bottom first while the other is still not in place, resulting in inconsistent insertion depths of the two wires B. The flush end face design ensures that the reference planes of the two clamping plates are unified in the insertion direction. When the insertion drive module 300 moves to the preset stroke, the two wires B reach the bottom of the insertion holes of the lamp board A simultaneously, with consistent insertion depths.

[0068] This implementation method eliminates the need for additional sensor feedback or complex travel compensation algorithms, ensuring consistent insertion depth for dual-wire connections and is suitable for most A-wire connection processes on lamp boards.

[0069] In some possible embodiments, such as Figure 3-4 As shown, the opening and closing motion of the first wire clamp 100 and the second wire clamp 200 includes at least one of the swing type and the translation type; It also includes a first split-and-join drive module 110 and a second split-and-join drive module 210. The first split-and-join drive module 110 and the second split-and-join drive module 210 include at least one of a finger cylinder, an electromagnet, and a motor. The first wire clamp 100 is disposed on the output end of the first split-and-join drive module 110, and the second wire clamp 200 is disposed on the output end of the second split-and-join drive module 210.

[0070] As an optional implementation of this invention, the independent opening and closing movements of the first wire clamp 100 and the second wire clamp 200 are driven by their respective opening and closing drive modules. This is the structural basis for achieving independent control of the clamping force of the two wires B. Regarding the specific form of the opening and closing movement, the swing-type (i.e., scissor-type) mechanism achieves the opening and closing of the clamping plates by rotating around an axis. Its advantages are a compact structure, large clamping force, and suitability for space-constrained scenarios. The translational type guides the clamping plates to separate and close in parallel via a linear guide rail. Its advantages are that the clamping plates remain parallel throughout the opening and closing process, resulting in more uniform force on the wire B, making it suitable for scenarios requiring high clamping precision.

[0071] Regarding the selection of the drive source, finger cylinders are the most common clamping drive element in automated equipment, characterized by fast response, low cost, and high reliability, making them suitable for most general wiring scenarios. Electromagnets achieve attraction and release by controlling the on / off state of power and the magnitude of current, resulting in a simpler and more compact structure. However, their clamping force is relatively small and difficult to control precisely, making them suitable for scenarios with small wire diameters and low precision requirements. Motor drives (such as servo motors or stepper motors combined with lead screws or rack and pinion mechanisms) can achieve precise programmable control of position, speed, and clamping force, and can adapt to wires of different diameters and materials, making them suitable for high-end equipment with high requirements for wiring yield and process traceability. Of course, the above drive methods are all common existing technologies in this field, and this embodiment does not specifically limit them. Any drive device capable of independently driving the wire clamp to open and close should be within the scope of this embodiment.

[0072] In some embodiments, the first clamp 100 and the second clamp 200 may employ different opening and closing drive modules. For example, the first clamp 100 may be a translational type and the second clamp 200 may be a scissor type, which is suitable for different spatial adaptations and situations where the wire diameter specifications of the two wires B are different.

[0073] This implementation provides multiple independent driving methods for the two wire clamps, offering flexible options for wiring scenarios with different precision and cost requirements.

[0074] In some possible embodiments, such as Figure 2 As shown, both the first split-and-join drive module 110 and the second split-and-join drive module 210 are translational finger cylinders. The two first clamping plates 101 are respectively fixedly connected to the two pneumatic grippers of the first split-and-join drive module 110, and the two second clamping plates 201 are respectively fixedly connected to the two pneumatic grippers of the second split-and-join drive module 210. It also includes a bracket 320 for connecting the output end of the plug-in drive module 300. The first split-and-join drive module 110 and the second split-and-join drive module 210 are both fixedly connected to the bracket 320. The split-and-join movement stroke of the second split-and-join drive module 210 is not less than the split-and-join movement stroke of the first split-and-join drive module 110, and the split-and-join movement of the second split-and-join drive module 210 is not later than the split-and-join movement of the first split-and-join drive module 110.

[0075] As an optional implementation of the present invention, the specific selection of the driving module and the motion timing logic of the double wire clamps in the nested structure are further defined. As mentioned above, since the free end of the second wire clamp 200 is L-shaped and surrounds the free end of the first wire clamp 100 from the outside, the second wire clamp 200 is in the outer layer and the first wire clamp 100 is in the inner layer. During the opening and closing motion, if the opening stroke of the second wire clamp 200 is less than that of the first wire clamp 100, the L-shaped free end of the second wire clamp 200 may still be on the motion path of the first wire clamp 100, causing the first wire clamp 100 to physically collide with the second wire clamp 200 when opening or closing. Therefore, this embodiment ensures that the outer second wire clamp 200 can completely give way to the movement space of the inner first wire clamp 100.

[0076] Regarding the timing of the movements, i.e., the opening and closing movements of the second opening and closing drive module 210 are no later than those of the first opening and closing drive module 110, it should be understood that the opening and closing action of the outer second wire clamp 200 is not delayed in time compared to the inner first wire clamp 100; that is, the outer one moves first or moves synchronously. Combined with the nested structure, when separating after insertion, the second wire clamp 200 opens first, and then the first wire clamp 100 opens from the inside; when closing, the first wire clamp 100 starts first (or starts synchronously with the second wire clamp 200), and the first wire clamp 100 is in place first, after which the second wire clamp 200 subsequently encloses the inner first wire clamp 100, ensuring the safety and reliability of the nested structure during dynamic movement.

[0077] In a typical application scenario, the first splitting / closing drive module 110 (inner layer) uses a translational finger cylinder with a stroke of 6mm, while the second splitting / closing drive module 210 (outer layer) uses a translational finger cylinder with a stroke of 10mm. The stroke of the outer layer is significantly greater than that of the inner layer. Control is achieved by issuing commands from the same PLC, but by adjusting the throttle valve in the air circuit, the response speed of the outer layer cylinder is made slightly faster than that of the inner layer, ensuring that the outer layer reaches its position first. In actual operation, the two clamps did not collide during thousands of splitting / closing cycles.

[0078] By adopting this implementation method, the nested structure is extended from static design to dynamic operation through dual constraints of stroke and timing, ensuring the reliability of the mechanism in high-speed reciprocating motion.

[0079] In some possible embodiments, such as Figure 1 and Figure 7-9 As shown, the second split-opening drive module 210 is threadedly connected to the bracket 320 and is located at the free end of the first clamping plate 101 facing upward.

[0080] As an optional implementation of the present invention, the second splitting and joining drive module 210 (i.e., the drive source of the second wire clamp 200) is installed on the side facing the free end of the first clamping plate 101, that is, closer to the front end of the wire insertion station. This front-mounted installation method makes the second splitting and joining drive module 210 and the free end of the first clamping plate 101 more spatially close, shortening the projected length of the entire wire insertion mechanism in the wire insertion direction and making the overall volume more compact. In the automated production line with such a narrow space for assembling the lamp board A, the wire insertion mechanism is usually surrounded by equipment such as a vision inspection module, a wire feeding module, and positioning fixtures. A smaller wire insertion mechanism means more space for surrounding layout, higher mobility, and less interference with surrounding equipment.

[0081] Of course, it is not impossible to install the second split-and-comb drive module 210 in other locations, but from the perspective of reducing the overall size of the machine, the installation position provided in this embodiment is the preferred solution.

[0082] This implementation method employs a more compact layout of split-and-combine drive modules, further reducing the overall size and improving integration while maintaining the nested dual-clip functionality.

[0083] In some possible embodiments, such as Figure 7-9 As shown, it also includes a wiring module 310 disposed on the output end of the wiring drive module 300, and a bracket 320 fixedly connected to the output end of the wiring module 310. The wiring module 310 includes at least one of a cylinder and a linear motor, and the stroke direction of the wiring module 310 is parallel to or aligned with the wiring direction.

[0084] As an optional implementation of this invention, in automated wire insertion equipment, the wire insertion drive module 300 typically uses a lead screw motor in conjunction with a linear guide rail, with a relatively long stroke (usually 100-300mm), responsible for rapidly moving the entire wire clamp assembly from its initial position away from the lamp board A to above the lamp board A. If this module directly completes the final insertion action, the large inertia of the moving parts results in a strong impact upon arrival, which can easily damage the lamp board A or cause the wire B to bend. In this embodiment, a short-stroke wire insertion module 310 (such as a small cylinder or voice coil motor with a stroke of 10-30mm) is added between the output end of the wire insertion drive module 300 and the bracket 320, which is responsible for the final precision insertion. The wire insertion drive module 300 completes the rapid coarse placement, while the wire insertion module 310 completes the slow precision insertion; the two work together in a collaborative manner.

[0085] Specifically, the wire insertion drive module 300 quickly delivers the wire clamp assembly to a position approximately 5-15mm above the lamp board A. Subsequently, the wire insertion module 310 smoothly pushes the wire clamp assembly onto the surface of the lamp board A at a lower speed, completing the insertion of the wire B. This ensures both high overall cycle efficiency and reduces the impact of the insertion action on the lamp board A and the wire B, while also making it easier to ensure consistent insertion depth.

[0086] This implementation method ensures both insertion speed and accuracy, and improves insertion yield.

[0087] In some possible embodiments, such as Figure 4 As shown, the minimum distance d1 between the first insertion hole 103 and the outer end face of the free end of the first clamping plate 101, and the minimum distance d2 between the second wire groove 202 and the inner end face of the free end of the second clamping plate 201 are: 0.1≤d1, d2≤9.4mm, and 0.2mm≤d1+d2≤9.5mm; when the first clamping plate 101 and the second clamping plate 201 are close together, the minimum gap d3 between the free end of the first clamping plate 101 and the free end of the second clamping plate 201 is: 0≤d3≤9.3mm.

[0088] As an optional implementation of the present invention, d1 can also represent the end wall thickness of the first clamping plate 101, d2 represents the end wall thickness of the second clamping plate 201, and d3 is the gap between the outer end face of the first clamping plate 101 and the inner end face of the second clamping plate 201 when both clamps are close together.

[0089] In this embodiment, the lower limit of d1+d2≥0.2mm is based on the current precision machining capabilities and material stiffness limits. Considering that the scissor-type splitting and opening motion has no mechanical stroke interference in the same direction, theoretically, as long as the material stiffness is sufficient (such as using hard alloy or heat-treated stainless steel), d1 and d2 can approach 0.1mm. Therefore, the lower limit of d1+d2 is: min(d1)+min(d2)=0.2mm. This limit value can be applied to the automatic wiring scenario of micro PCB indicator lights, in which case the spacing of the wiring holes on the light board A may only be 1.5mm. Of course, in some cases, if a higher strength material is used to make the first clamping plate 101 and the second clamping plate 201, d1 and d2 can also be less than 0.1mm. For d3≥0, it means that when the two wire clamps come together, the end face gap is allowed to approach zero (that is, theoretically they can fit tightly together, such as the second splitting drive module 210 of the scissor type). The upper limit setting of max(d1+d2)≤9.5mm is based on the constraints of: the maximum hole spacing of the lamp board A (10mm), the minimum gap min(d3) between the outer end face of the first clamping plate 101 and the inner end face of the second clamping plate 201 = 0, and the minimum wire diameter of the conductor B (0.5mm). When the hole spacing of the lamp board A is 10mm, that is, the center distance between the two insertion holes is 10mm, if d1+d2 is too large, the edge distance between the two insertion holes will exceed the margin after subtracting the wire diameter from 10mm, resulting in the inability to align the two insertion holes simultaneously. d3≤9.3mm is the maximum allowable end face gap under this extreme condition, taking the maximum hole spacing of 10mm and the minimum wire diameter of 0.5mm, that is: max(hole spacing)-min(d1+d2)-min(wire diameter)=10-0.2-0.5=9.3mm.

[0090] It should be emphasized that if the space on the lamp board A is ample and the hole spacing is large (e.g., exceeding 15mm), two independent single wire clamps can be used directly to complete the wiring. Although this solution can also be applied, the cost is higher due to the high manufacturing precision requirements, making the application advantage less obvious. Therefore, the two wire clamps provided in this embodiment are more advantageous in the field of wiring assembly for small-sized lamp boards A.

[0091] This implementation provides a wiring assembly mechanism that can cover everything from miniature PCB indicator lights to high-power lamp boards A, and is particularly suitable for wiring scenarios with narrow spaces and small spacing.

[0092] Furthermore, in some possible embodiments, such as Figure 4 As shown, the minimum distance d1 between the first insertion hole 103 and the outer end face of the free end of the first clamping plate 101, and the minimum distance d2 between the second wire groove 202 and the inner end face of the free end of the second clamping plate 201 are: 0.5mm≤d1=d2≤4mm; when the first clamping plate 101 and the second clamping plate 201 are close together, the minimum gap d3 between the free end of the first clamping plate 101 and the free end of the second clamping plate 201 is: 0.5mm≤d3≤1mm.

[0093] As an optional implementation of this invention, the mainstream light bulbs are generally standard incandescent bulbs and LED bulbs. The spacing between the wires B on their lamp board A is usually 5-8mm, and the wire diameter of wire B is 0.8-1.5mm. The clamping material in the insertion machine used is usually aluminum alloy or stainless steel. Under this condition, the symmetrical wall thickness design of d1=d2=0.5-4mm ensures the structural strength of the wire groove edge and leaves sufficient expansion margin; the end face gap of d3=0.5-1mm is the most common safe movement gap, which can ensure the compactness of the nested structure and is easy to maintain under conventional machining accuracy.

[0094] This implementation provides a wire clamp solution that is more suitable for assembling the wiring of mainstream light bulb products.

[0095] Example 2: Please see Figure 5 The opening and closing motion of the first clamp 100 and the second clamp 200 is oscillating.

[0096] As an optional implementation of the present invention, specifically, the swing-type opening and closing motion is a scissor-like structure. The two clamping plates are hinged by a pin, and the opening and closing is achieved by the opening and closing drive module pushing the clamping plates to rotate around the pin. Compared with the translational type in Embodiment 1, the advantage of the swing-type structure is that the structure is more compact: under the same required opening and closing motion stroke, the drive stroke required based on the lever structure is less, and with the same output force and lever arm of the opening and closing drive module, the clamping force of the free ends of the first clamping plate 101 and the second clamping plate 201 on the wire B is greater, which is suitable for scenarios requiring a larger clamping force, and the required plate thickness is smaller. In addition, under the scissor-like opening and closing motion, there is no physical stroke interference in the same direction when the clamping plates of the two wire clamps come together, and theoretically the two end faces can be infinitely close, which provides a structural basis for the realization of the extremely small d3 gap mentioned above.

[0097] Furthermore, the first split-opening drive module 110 and the second split-opening drive module 210 are swing finger cylinders with an opening angle of -10° to 30°. The length of the first clamping plate 101 and the second clamping plate 201 is 40mm, and the opening and closing stroke of the free end is about 14mm, which is sufficient to accommodate two wires B and complete the clamping.

[0098] This implementation provides an alternative splitting and merging motion method, which is more compact in structure and more suitable for miniature light board A wiring scenarios with extremely demanding space requirements.

[0099] Example 3: Please see Figure 10-14 The present invention also provides the following technical solutions: The lamp panel wiring module includes the wiring mechanism of embodiment 1 or 2, and also includes a wiring drive module 300. The wiring drive module 300 includes at least one of a linear guide rail and a lead screw motor, and further includes: The wire feeding mechanism 400 includes a wire separating wheel set 410 and a drive wheel set 420. The wire separating wheel set 410 is used to separate the wire B, and the drive wheel set 420 is used to drive the wire B to move in the insertion direction and is located in the wire output direction of the wire separating wheel set 410. The wire cutting mechanism 500 includes a fourth split-and-join drive module 510 located in the wire output direction of the drive wheel assembly 420 and a wire cutting part 530 provided on the output end of the fourth split-and-join drive module 510. The fourth split-and-join drive module 510 includes at least one of a finger cylinder, a lead screw sleeve mechanism, a linear motor, and a reciprocating swing mechanism. Each guide wheel 411 in the guide wheel 411 group has at least two guide grooves 412 on its shaft side wall for accommodating a single guide wire B, and at least two cutting edges 531 are provided at the opposing ends of the two wire cutting parts 530; the arrangement direction of the cutting edges 531 on the wire cutting part 530, the axial direction of the drive wheel group 420, and the arrangement direction of the two insertion holes are aligned or parallel to each other.

[0100] As an optional implementation of the present invention, this embodiment provides a complete insertion module to automate the entire process from feeding the wire B to cutting and insertion. Specifically, after the two wires B with their sheaths connected together leave the winding wheel, they enter the two wire grooves 412 on the wire wheel 411. Since the wire grooves 412 are spaced apart (otherwise they would only be considered as one groove), the two wires B are directly pulled apart and kept parallel and equidistant. The drive wheel set 420 feeds the wire B to the insertion direction at a constant speed to a preset length. The fourth splitting drive module 510 in the wire cutting mechanism 500 drives the two wire cutting parts 530 to move towards each other, and the cutting edge 531 cuts the wire B to complete the wire cutting. The alignment or parallelism of the cutting edge 531, the axial direction of the drive wheel set 420, and the alignment of the insertion holes ensures that the wire B does not undergo radial twisting during the entire process from feeding to clamping to insertion, and is always aligned with the interface A1 on the lamp board A in the correct posture.

[0101] When the number of wire slots 412 and blades 531 exceeds two, it can also be adapted to wiring scenarios with three or more wires B.

[0102] Specifically, in some possible embodiments, such as Figure 6 As shown, it also includes a third wire clamp 600, which includes a third split-opening drive module 610 and two third clamping plates 601 disposed on the output end of the third split-opening drive module 610. The free ends of the two third clamping plates 601 are in opposite L-shapes, and the distance between the handles of the two free ends of the third wire clamp 600 is greater than the total width of the free ends of the two second clamping plates 201. When the two free ends of the third wire clamp 600 are brought together, they can surround the free ends of the two second clamping plates 201. The free ends of the two third clamps 601 are provided with third wire grooves 602 on their facing surfaces. When the third clamps 600 come together, the two third wire grooves 602 form a third insertion hole 603.

[0103] It should be noted that for multi-wire B (three or more wires) scenarios, since the nested structure in this solution is essentially "one layer inside another," the free ends of all wire clamps must be in a straight line to achieve multi-layer nesting. However, the insertion holes on each wire clamp can be arranged in a straight line or a curve (e.g., Figure 6As shown, the arrangement of the three insertion holes is at an angle relative to the length direction of the clamping plate. This is suitable for assembling wires on lamp board A where the interfaces A1 are arranged linearly (straight or curved). For cases where the interfaces A1 are arranged in an isosceles triangle or polygon (i.e., at least two interfaces A1 are arranged laterally and perpendicular to the length direction of the clamping plate), nesting will not be possible. However, this can be solved by changing the feeding direction of lamp board A itself, the placement direction of lamp board A, or by replacing the appropriate wire clamp.

[0104] Of course, the number of nesting layers is not limited to two or three layers. Based on this principle, it can be further extended to four, five or even more layers to accommodate the wiring needs of more wires B in the lamp board A. This embodiment does not limit this.

[0105] This implementation provides a complete wiring fixture for automatic wiring of lamp board A, which is applicable to situations where two or more wires B need to be assembled, and has greater adaptability.

[0106] In some possible embodiments, such as Figure 13-14 As shown, the wire guide wheel assembly 410 includes two rows of freely rotatable guide wheels 411, with the axes of each guide wheel 411 parallel and each guide groove 412 axially aligned. The two rows of guide wheels 411 are connected by an elastic element 413, and the elastic element 413 has a force that pulls the two rows of guide wheels 411 together in the initial state.

[0107] As an optional implementation of the present invention, a scheme for shaping conductor B is provided to ensure that conductor B exits in a straight line. Furthermore, during the simultaneous transport of multiple conductors B, a constant spacing and parallelism must be maintained between each conductor B, and each conductor B needs to be subjected to a suitable clamping force to prevent slippage. In this embodiment, two rows of conductor wheels 411 are connected by elastic elements 413 (such as tension springs, elastic ropes, or by setting compression springs on the outside of the two rows of conductor wheels 411 and setting a guide structure between the two rows of conductor wheels 411). In the initial state, the elastic elements 413 pull the two rows of wheels together, so that the conductors B in each conductor groove 412 are subjected to a uniform clamping force. When there are tolerance differences in the conductor diameter, the elastic elements 413 can automatically expand and contract to compensate, ensuring that both thicker and thinner conductors B can be reliably clamped and synchronously straightened and transported.

[0108] Specifically, the wire grooves 412 on the sidewall of each guide wheel 411 are aligned axially, forming at least two parallel wire channels B. The axes of the two rows of wheels are arranged in parallel, and the wire B passes between the two rows of wheels, receiving balanced clamping forces from both sides.

[0109] By adopting this implementation method, the elastic floating clamp design automatically adapts to the tolerance differences of the wire diameter of conductor B, ensuring the synchronization, straightening effect and positioning accuracy of multiple conductors B during the conveying process.

[0110] In some possible embodiments, such as Figure 11 and Figure 17 As shown, the drive wheel assembly 420 includes two rollers 421. The shafts of the two rollers 421 are connected together by a synchronous belt or synchronous gear and driven by a motor and a rotary cylinder to ensure that the wire feeding length and wire exit length of the two wires B are consistent, and to avoid uneven wire feeding that would lead to inconsistent insertion depth of subsequent wires.

[0111] In some possible embodiments, such as Figure 12 and Figure 15 As shown, the wire cutting mechanism 500 also includes a connecting plate 520. The two connecting plates 520 are respectively fixedly connected to the two output ends of the fourth split-and-comb drive module 510. The two wire cutting parts 530 are both located at the opposite ends of the connecting plates 520, and the wire cutting parts 530 are provided in two sets along the wire insertion direction.

[0112] As an optional implementation of the present invention, when the straightened wire B reaches the wire cutting section 530, the wire cutting section 530 can cut off the wire B to ensure that its end is flat. Furthermore, since the wires B used for wiring assembly on the lamp board A generally need to have both ends exposed, a wire stripping process is generally required before wiring. Although the aforementioned solution can use another wire stripping mechanism for wire stripping, for example, a set of wire stripping wheels with controllable opening and closing action can be set in the wire wheel group 411 (i.e., two wire stripping wheels can move separately and together, and the groove on its shaft side wall for accommodating the wire B has a blade that can cut into the wire insulation; when the wire stripping wheel rotates, it cuts the wire insulation on the surface of the wire B into two halves), the wire stripping and cutting actions can also be achieved through the cooperation of the wiring module and the wire cutting mechanism 500, for example: In a typical application scenario, located in the 520 input direction of the connecting board ( Figure 15 The initial spacing of the wire-cutting section 530 (upper part) is small, used for cutting into the insulation, located in the wire-out direction of the connecting plate 520 ( Figure 15The initial spacing of the wire-cutting section 530 (lower part) is relatively large, used for the final cutting of conductor B (including the wire core). During wire exit, the fourth split-and-joint drive module 510 first separates the two connecting plates 520, causing all wire-cutting sections 530 to separate; the drive wheel set 420 drives conductor B towards the insertion direction, causing a portion of conductor B to enter below the upper wire-cutting section 530; the two connecting plates 520 close, and the upper wire-cutting section 530, due to its smaller spacing, first cuts into the insulation of conductor B without damaging the wire core; after cutting into the insulation, the two connecting plates 520 separate; the insertion mechanism moves to this point and clamps the insulation portion of conductor B located below the upper wire-cutting section 530. The drive wheel set 420 remains stationary, and the insertion mechanism pulls towards the insertion direction, pulling off the cut insulation to complete the stripping; subsequently, the two clamps of the insertion mechanism separate. The clamp opens and moves a distance in the opposite direction of the insertion direction, closing onto the exposed wire core of conductor B after stripping. The insertion mechanism and drive wheel assembly 420 work together to move conductor B to the appropriate length in the insertion direction. The two connecting plates 520 close again, the upper wire-cutting part 530 cuts the wire core of conductor B, and the lower wire-cutting part 530 cuts the wire insulation of conductor B. Maintaining the posture of the connecting plate 520, the insertion drive module 300 drives the clamp to perform the insertion action. Due to the maintenance of the posture, the wire insulation on the upper part of conductor B is pulled down by the axial limit of the wire-cutting part 530 located at the lower part of the connecting plate 520. After the insertion drive module 300 resets, the above actions are repeated to cycle through stripping and cutting wire insulation.

[0113] Of course, the functions of stripping and cutting wires can also be achieved through other action combinations or by changing the upper and lower spacing. For example, a single wire cutting section 530 can be used in conjunction with a multi-segment stroke control of the split-and-joint drive module (the first shallow cut is for stripping, and the second deep cut is for cutting the wire), or the upper and lower spacing can be changed so that the upper spacing is larger for stripping and the lower spacing is smaller for cutting the wire. These methods are all within the scope of this embodiment.

[0114] This implementation method integrates wire stripping and wire cutting functions into the same mechanism, eliminating the need for a separate wire stripping station, simplifying equipment layout, and improving automation.

[0115] In some possible embodiments, such as Figure 16 As shown, the cutting edge 531 is either V-shaped or arc-shaped, and the cutting part 530 is plate-shaped. The transverse width of each cutting edge 531 gradually changes along the insertion direction, and the tapering directions of the two cutting parts 530 in the same group are opposite. The two cutting parts 530 in the same group located on the two surfaces with the smallest width of the cutting edge 531 can overlap in the insertion direction.

[0116] As an optional implementation of the present invention, the V-shaped or arc-shaped cutting edge 531 can automatically guide the wire B to the cutting center, preventing the wire B from slipping during cutting. The lateral width of the cutting edge 531 gradually changes (narrows) along the insertion direction, so that the cutting force gradually concentrates from the wide part of the cutting edge 531 to the narrow part, realizing a progressive cutting similar to scissors, which makes cutting more labor-saving and produces a neat cut. The two surfaces of the two cutting parts 530 in the same group with opposite narrowing directions and the two surfaces with the smallest cutting edge 531 width can overlap in the insertion direction, forming an interlaced cutting surface, which further improves the cutting reliability.

[0117] By adopting this implementation method, automatic guidance and progressive shearing are achieved through the geometric design of the cutting edge 531, which improves the shearing reliability and cross-sectional quality, while extending the service life of the cutting edge 531.

[0118] Example 4: Please see Figure 18-19 The present invention also provides the following technical solutions: The lamp panel wiring machine includes the wiring module of Embodiment 3, and also includes a feeding module 700 for conveying lamp panel A. The feeding module 700 includes: Fixture 710 is used to place lamp panel A. Fixture 710 includes one of guide rail and conveyor belt. The feeding drive module 720 is used to drive the lamp board A or the fixture 710 to move. The feeding drive module 720 includes one of the following: a push plate mechanism 721 and a motor. When lamp board A is placed on fixture 710, interface A1 on lamp board A is aligned with or parallel to the wiring direction.

[0119] In this embodiment, the fixture 710 in the feeding module 700 is used to position and support the lamp board A. The feeding drive module 720 transports the lamp board A or the fixture 710 supporting the lamp board A to the insertion station. When the lamp board A is placed, its interface A1 is aligned or parallel to the insertion direction to ensure that the wire B can be inserted in a straight line without bending.

[0120] Specifically, the fixture 710 can be a double-track 711 type or a conveyor belt type (with a hollowed-out design at the interface A1 on the aligned light panel A). The double-track 711 type has a simple structure and high positioning accuracy, making it suitable for small-batch, multi-variety production; the conveyor belt type has higher conveying efficiency and is suitable for large-batch, continuous production of a single variety. The pusher mechanism 721 in the feeding drive module 720 can use intermittent pushing, synchronized with the insertion cycle; the motor is more suitable for driving conveyor belts and similar conveyor methods.

[0121] This implementation method enables automated production from feeding the lamp board A to inserting the wire B.

[0122] In some possible embodiments, such as Figure 20As shown, the fixture 710 includes two mutually spaced tracks 711. Each track 711 has a limiting groove 712 extending through the length of the guide rail on its facing surface. The feeding drive module 720 is a push plate mechanism 721. The push plate mechanism 721 includes a push plate drive unit 722 and a push block 723 disposed on the output end of the push plate drive unit 722. The push plate drive unit 722 includes one of a cylinder and a linear motor.

[0123] As an optional implementation of the present invention, the double track 711 and the limiting groove 712 clamp the edges of the lamp plate A from both sides, so that the lamp plate A maintains a stable posture and orientation during the conveying process. The push plate mechanism 721 pushes the lamp plate A to move step by step along the track 711 through the push block 723, moving one station interval at a time, synchronized with the insertion cycle.

[0124] This implementation provides a low-cost, high-reliability intermittent feeding solution suitable for intermittent wiring assembly mechanisms.

[0125] In some possible embodiments, such as Figure 18-20 As shown, a spacing adjustment mechanism 713 is also provided between the two tracks 711, and the travel direction of the spacing adjustment mechanism 713 is perpendicular to the length direction of the track 711.

[0126] As an optional implementation of the present invention, the spacing adjustment mechanism 713 makes the spacing between the two tracks 711 adjustable, thereby accommodating lamp panels A of different widths. In actual production, the same production line may need to assemble bulbs of different specifications (such as lamp panels A of different sizes for A19 and G45 bulbs). If the width of the fixture 710 is fixed, the fixture 710 needs to be replaced, affecting production efficiency.

[0127] The spacing adjustment mechanism 713 is usually composed of common lead screws and sleeves or cylinders. Operators can manually or automatically adjust the spacing of the track 711 quickly. This embodiment does not make specific limitations on this.

[0128] This implementation method allows the same equipment to adapt to various specifications of lamp boards A, reducing changeover time and improving the flexibility and utilization of the equipment.

[0129] In some possible embodiments, as shown in the figure Figure 17 As shown, it also includes a mounting bracket 800, a wire insertion drive module 300, a wire feeding mechanism 400, and a wire cutting mechanism 500, all of which are fixedly connected to the mounting bracket 800; it also includes: The alignment adjustment mechanism 810 includes one of a linear motor, a cylinder, and a lead screw and sleeve mechanism. The mounting bracket 800 is fixedly connected to the output end of the alignment adjustment mechanism 810, and the stroke direction of the alignment adjustment mechanism 810 is parallel to the conveying direction of the feeding module 700.

[0130] As an optional implementation of the present invention, after the lamp board A is conveyed to the insertion station by the feeding module 700, due to the cumulative conveying error and the manufacturing tolerance of the fixture 710, the actual position of the lamp board A may have a slight deviation from the preset insertion position; or the insertion machine needs to operate continuously, so that the insertion module can perform the insertion task on the continuously moving feeding module 700. This requires the insertion module to be able to move along the conveying direction of the feeding module 700. Therefore, this embodiment further adds an alignment adjustment mechanism 810 to ensure that the wire B and the interface A1 on the lamp board A can be accurately aligned.

[0131] Specifically, the alignment adjustment mechanism 810 can be triggered by the vision positioning system—the vision module captures the position of interface A1 on the light panel A, calculates the deviation value from the preset position, and the alignment adjustment mechanism 810 moves to compensate according to the deviation value. Alternatively, it can be based on closed-loop control of a distance sensor and a servo system. This embodiment does not limit this.

[0132] This implementation method further ensures the yield rate of wire assembly.

[0133] The working principle and usage process of this invention are as follows: First, the lamp board A is placed on the fixture 710. The feeding drive module 720 transports the lamp board A to the insertion station, with the interface A1 on the lamp board A aligned with the insertion direction. The wire feeding mechanism 400 uses a wire separating wheel set 410 to separate the two wires B and keep them parallel and equidistant. The drive wheel set 420 transports the wires B towards the insertion direction to a preset length. The insertion drive module 300 drives the insertion mechanism to move to the output end of the feeding mechanism 400, where both wire clamps close, clamping the two wires B. Driven by the drive wheel set 420 and the insertion drive module 300, the wires move along the insertion direction to the required length. Subsequently, the wire cutting mechanism 500 completes the wire cutting, and the wire insertion drive module 300 drives the wire insertion mechanism to move to the lamp board A. The wire insertion module 310 drives the second wire clamp 200 and the first wire clamp 100 to move along the wire insertion direction, inserting the two wires B into the corresponding wire insertion holes of the lamp board A at the same time. After the wire insertion is completed, the first wire clamp 100 and the second wire clamp 200 release the wires B simultaneously and reset, repeating the next wire insertion operation.

[0134] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
