Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to an automated assembly equipment for wires and sheets. Background Technology

[0002] In the current electronics manufacturing industry, the pre-welding assembly of wires and mesh sheets (such as heating elements, metal mesh sheets, etc.) generally relies on manual operation. Workers need to manually thread the wires into the positioning holes of the sheet, then cover them with a cover plate for temporary fixation, and then move them to the laser welding station.

[0003] The above methods have several drawbacks. First, the positioning accuracy of the wire and the sheet is difficult to guarantee. During manual threading, the wire is prone to misalignment or twisting, preventing it from accurately embedding into the micro-positioning holes of the sheet. Furthermore, the alignment of the cover plate and the sheet requires repeated adjustments, resulting in low assembly efficiency. Second, the welding quality is unstable. Uneven pressure during manual pressing of the cover plate can easily cause sheet deformation or wire dislocation, often leading to defects such as incomplete welds and misalignment. Finally, the multi-station coordination is costly. The assembled semi-finished product needs to be manually transported to the welding equipment, during which the sheet is prone to shifting. After welding, the cover component must be manually disassembled, making the process cumbersome and labor-intensive.

[0004] Although some companies have attempted to use simple jigs to assist in positioning, existing jigs are limited in function, only able to fix the sheet metal but unable to simultaneously constrain the wire position, and lack an automatic pressing mechanism, still relying on manual alignment of the cover plate and pressing for fixation. More importantly, such jigs cannot achieve automatic connection with the welding station, and the movement process requires interrupting the production line. These shortcomings lead to rising labor costs, prominent capacity bottlenecks, and difficulties in controlling product consistency for electronics factories. Therefore, there is an urgent need to develop an assembly equipment that integrates automatic positioning, pressing, and station switching functions to fundamentally solve the problems of inaccuracy, low efficiency, and quality fluctuations caused by manual operation. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide an automated assembly equipment for wires and sheets, aiming to solve the problems of low automation, low assembly efficiency, and low quality uniformity in the existing wire and sheet assembly methods.

[0006] To achieve the above objectives, this utility model provides an automated assembly equipment for wires and sheets, including a fixture mounted on a support, and first cylinder pressure head assemblies disposed opposite each other on both sides of the fixture. A wire ejector assembly is provided at the bottom of the fixture.

[0007] The top surface of the fixture is provided with a series of wire-fixing grooves. The two ends of the wire-fixing grooves extend downward to form wire-passing holes for pressing in the wire. The wire-fixing grooves are provided with pin holes that pass downward through the fixture. The top surface of the fixture is also provided with positioning pins for positioning the mesh sheet and the cover plate hole of the first cover plate after placing the mesh sheet and the first cover plate.

[0008] The first cylinder pressure head assembly includes a first cylinder located below one side of the end of the fixture. The bottom of the first cylinder is connected to a connecting rod, and the top of the connecting rod is connected to the tail of the pressure plate head via a first rotating shaft seat. The bottom side of the pressure plate is movably connected to the side of the fixture, and the top forms an elbow structure for downward pressing.

[0009] The wire ejector assembly includes ejector cylinders disposed below the fixture. A lifting plate is connected to the top of each ejector cylinder. Each lifting plate is equipped with a movable joint, and each movable joint is provided with an ejector pin corresponding to the ejector pin hole.

[0010] As a further embodiment of this utility model, a second cover plate is provided above the first cover plate. On both sides of the fixture, and outside the first cylinder pressure head assembly, a second cylinder pressure head assembly is also provided for pressing the second cover plate downward. The second cylinder pressure head assembly includes a cover plate pressure head movably connected to both ends of the fixture. The cover plate pressure heads on both sides are bracket-shaped, with their tops pressed down to contact the second cover plate. The bottom of the cover plate pressure head is connected to the second cylinder through a second rotating shaft seat.

[0011] As a further embodiment of this invention, a spring for uniform pressure is fitted at the bottom of the ejector pin and inside the movable joint.

[0012] As a further improvement of this utility model, each of the movable joints is fixed to a fixed plate.

[0013] As a further improvement of this utility model, the fixture is an integrally formed perforated groove structure.

[0014] As a further improvement of this utility model, the bottom of the bracket is provided with a transfer assembly for moving the overall structure on both sides.

[0015] As a further embodiment of this utility model, the transfer assembly includes a slide connected to the bottom of the bracket, the slide being located on a guide rail, and a lead screw being provided on the guide rail, one end of which is connected to a servo motor via a coupling.

[0016] The beneficial effects of this utility model are as follows:

[0017] This solution uses the positioning groove and positioning pin on the fixture to ensure that the wire is embedded in the positioning hole of the mesh sheet without displacement (e.g.,Figure 4 The jig structure, along with the spring-loaded, evenly pressurized ejector pin and fixed plate structure in the wire ejector pin assembly, ensures precise ejector pin lifting and lowering, completely eliminating twisting and misalignment caused by manual threading. Addressing the issue of low efficiency, the first cylinder pressure head assembly employs a lever transmission design (the cylinder pushes the connecting rod, which is converted into downward pressure on the pressure plate head via the first rotating shaft seat), and the second cylinder pressure head assembly uses a bracket-shaped cover plate pressure head to apply pressure synchronously. This achieves multi-layer automatic pressing of the mesh sheet, the first cover plate, and the second cover plate, shortening the assembly time for a single piece. Furthermore, addressing the problem of quality fluctuations, the integrated molding jig, combined with the transfer assembly (including a servo motor-driven lead screw slide rail system), allows the assembled semi-finished product to be precisely transferred to the welding station, completely avoiding sheet displacement caused by manual handling. Figure 2 (Schematic diagram of transfer structure), combined with the automatic alignment of the pin hole and welding equipment, reduces the rate of false welds and achieves high-precision, high-efficiency, and high-consistency fully automated production.

[0029] as follows:

[0030] Please see the appendix Figure 1-9 ,

[0031] The fixture (1) of the automated assembly equipment in this solution is fixed on the bracket (2), and the first cylinder pressure head assembly (21) is symmetrically installed on both sides. The bottom is integrated with the wire ejector assembly (3). The top surface of the fixture (1) is provided with a wire positioning groove (10) for placing the wire (5). The two ends of the wire positioning groove (10) extend to the wire through holes (12) for pressing the wire (5) in. The groove has ejector holes (11) that pass through the fixture (1) and are equipped with positioning pins (13) for accurately placing the mesh sheet (4) and the first cover plate (14) to ensure that the positioning hole (40) of the sheet is aligned with the hole (140) of the cover plate. The first cylinder pressure head assembly (21) is connected in such a way that the first cylinder (210) below the end of the fixture (1) pushes the connecting rod (211) connected at the bottom to move upward through the upward movement. The top of the connecting rod (211) drives the tail of the pressure plate head (213) through the first rotating shaft seat (212). The bottom side of the pressure plate head (213) is movably hinged to the side of the fixture (1) to form a lever mechanism. In this way, the upward force of the cylinder (210) is converted into the downward pressing action of the bent structure at the top of the pressure plate head (213), which firmly fixes the mesh sheet (4) and the first cover plate (14) on the fixture (1). Meanwhile, the operation of the wire ejector assembly (3) is that when the ejector cylinder (30) below the fixture (1) rises, it pushes the lifting plate (31) connected to the top to move upward. The movable joint (32) installed in the lifting plate (31) moves accordingly, driving the ejector (33) to pass through the ejector hole (11) and hold the wire (5) to assist in welding. The whole process is automated and coordinated, without the need for manual intervention.

[0032] This technical solution significantly improves the level of automation. The linkage between the first cylinder pressure head assembly (21) and the wire ejector assembly (3) enables the wire (5) to be automatically pressed into the threading hole (12) and the cover plate to be pressed, which solves the common problem of wire (5) offset or twisting in manual operation and ensures high positioning accuracy. Secondly, the assembly efficiency is significantly improved. For example, the lever-type pressure plate head (213) design makes the downward pressure evenly distributed, avoiding deformation of the material or displacement of the wire (5). Combined with the precise extension and retraction of the ejector (33), the time for repeated adjustment is reduced, and the quality uniformity is guaranteed. The positioning pin (13) and the ejector hole (11) cooperate to ensure the stable alignment of the mesh material (4), the cover plate and the wire (5), eliminating the risk of false welding or misalignment. Moreover, the uniform pressure mechanism of the spring (330) of the wire ejector assembly (3) enhances the stability. The overall structure is compact and reliable, which greatly reduces labor costs and quality fluctuations.

[0033] Reference Appendix Figure 2 , 3 In a preferred embodiment of this utility model: a second cover plate (15) is preferably added above the first cover plate (14), and a second cylinder pressure head assembly (22) is symmetrically arranged on both sides of the fixture (1) and outside the first cylinder pressure head assembly (21). The assembly includes a bracket-shaped cover plate pressure head (222) that is movably connected to both ends of the fixture (1). The top of the cover plate pressure head (222) presses down to contact the second cover plate (15), and the bottom is connected to the second cylinder (220) through the second rotating shaft seat (221). Next, the second cylinder (220) drives the cover plate pressure head (222) to press down, providing additional clamping force to ensure that the second cover plate (15) is firmly fixed, preventing the mesh sheet (4) or wire (5) from shifting during assembly, thereby further improving the uniformity of welding quality, eliminating the risk of false welding or misalignment, enhancing the overall automation level, reducing manual adjustment time, improving assembly efficiency, and forming a secondary clamping with the first cylinder pressure head assembly (21), making the equipment more reliably adaptable to the clamping requirements of cover plates of different thicknesses.

[0034] Reference Appendix Figure 9 In a preferred embodiment of this utility model, a spring (330) structure is added inside the movable joint (32) of the wire pin assembly (3).

[0035] Specifically, a spring (330) is fitted at the bottom of the ejector pin (33) and fixed to the inner cavity of the movable joint (32). Through the elastic and uniform pressure characteristics of the spring (330), the spring (330) pushes the ejector pin (33) to press the wire and the mesh sheet (4) when the ejector pin cylinder (30) moves upward. The spring (330) has a uniform pressing effect, making the pressure more balanced.

[0036] Reference Appendix Figure 1 , 9In a preferred embodiment of this utility model, each movable joint (32) is fixed on a fixed plate (34), which enhances the stability and accuracy of the pin movement.

[0037] Specifically, when the ejector cylinder (30) drives the lifting plate (31) to move up and down, the movable joint (32) no longer floats independently but is uniformly constrained on the fixed plate (34), ensuring that all ejector pins (33) remain aligned during synchronous lifting and lowering, avoiding deviation in the crimping position of the wire (5) due to the offset of individual movable joints (32), and improving the positioning accuracy of the wire (5) and the mesh sheet (4) at the welding station.

[0038] Reference Appendix Figure 4 In a preferred embodiment of this utility model, the fixture (1) provided by this solution adopts an integrally formed perforated groove structure. By utilizing the high strength characteristics of stainless steel, the fixture (1) is improved in terms of its resistance to deformation during long-term high-frequency pressing operations. This avoids the displacement of key structural positions such as the wire groove (10) and the pin hole (11) caused by metal fatigue, and maintains the long-term stability of the positioning accuracy of the wire (5) and the mesh sheet (4). The integral forming process enables the relative positions of the wire groove (10), the wire hole (12) and the positioning pin (13) to achieve millimeter-level precise matching, eliminate the cumulative error of multi-part assembly, and ensure that the wire (5) is always coaxially aligned with the positioning hole (40) of the sheet when it is pressed into the wire hole (12).

[0039] Reference Appendix Figure 2 In a preferred embodiment of this utility model: the present solution preferably integrates a transfer component (6) at the bottom of the bracket (2). The component is fixedly connected to the bracket (2) through a slide (64). The slide (64) is embedded in the guide rail (63) and driven by the lead screw (62). The end of the lead screw (62) is linked with the servo motor (60) through the coupling (61), so that the whole equipment can automatically slide between the assembly station and the welding station, eliminating the manual handling of semi-finished products and eliminating the risk of material displacement caused by traditional manual handling. The servo motor (60) controls the slide (64) to be precisely positioned through the lead screw (62), ensuring that the mesh material (4) and wire (5) on the fixture (1) always maintain a stable alignment during the movement. After the equipment is assembled, it is automatically transferred to the welding station. After welding (or other assembly) is completed, it automatically returns to the loading station.

[0040] Reference Appendix Figure 2In a preferred embodiment of this utility model, this solution can also be assembled with a transfer assembly (6) to achieve displacement processing. Specifically, the slide (64) is fixedly connected to the bottom of the bracket (2), and the slide (64) is precisely embedded in the slot of the guide rail (63). At the same time, the slide (64) is driven to move by the lead screw (62) on the guide rail (63). One end of the lead screw (62) is connected to the output shaft of the servo motor (60) via a coupling (61). The servo motor (60) directly drives the lead screw (62) to rotate through the coupling (61).

All equivalent structural transformations made based on the present utility model's technical concept and the contents of the present utility model's technical solution specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
