Description

Technical Field

[0001] This utility model relates to the field of welding process equipment for high-frequency welding machines with silver solder wire, and in particular, to a universal automated welding equipment for stabilizing the voltage of mirror temples and hinges. Background Technology

[0002] One end of the temple is connected to a temple cover, and the other end is welded with a hinge. The hinge is connected to the frame's post hinge. The traditional way to process temples and hinges is to hold the temple with one hand, install the hinge to the fixture with the other hand, and then pick up the silver sheet and place it between the temple and the hinge. One foot starts the press, and the other foot starts the welding machine. This requires using both hands and feet, which is difficult to operate and results in a high scrap rate.

[0003] The existing Chinese utility model patent, application number 202110344822.1, entitled "A Novel Fully Automatic Laser Welding Machine for Eyeglass Temple Hinges," discloses a machine frame and a feeding bin, a vibration platform, a vision CCD camera, a four-axis robot, a secondary positioning fixture, an eyeglass temple material rack, a four-axis module, a loading fixture, a turntable mechanism, and a laser welding module mounted on the frame. The feeding bin includes a feeding bin outlet, and the vibration platform includes a feeding inlet. The feeding outlet of the feeding bin is aligned with the feeding inlet of the vibration platform. The vision CCD camera is located above the vibration platform for photographing the hinges on the platform. The four-axis robot includes grippers that grasp the hinges on the vibration platform and place them into the secondary positioning fixture that cooperates with the hinges. The eyeglass temple material rack is used to hold eyeglass temples. The four-axis module cooperates with the eyeglass temple to grip the eyeglass temples on the material rack and place them into the loading fixture. The eyeglass temple material rack is mounted on the turntable mechanism, which drives the loading fixture. After the jig holding the temple is rotated to the first welding position that matches the hinge, the hinge and both sides of the temple are laser welded by the laser welding module. This achieves the effect of "providing a new type of fully automatic laser welding machine for temple hinges, realizing the full automation of the laser welding process, and enabling convenient and quick switching of the production of various types of temples".

[0004] However, the following defects exist: 1. There are size errors in the temples and hinges produced by the same manufacturer. Also, because of the automated production, the welding machine is set to be consistent. If the product is thick (larger in size), the copper material will soften during heating if the pressure is too high and it is easy to deform. If the product is thin (smaller in size), the silver sheet may not be able to form good contact if the pressure is too low, resulting in weak welding or even incomplete welding. In short, it is necessary to stabilize the pressure on the temples, silver sheet, and hinges. 2: The positioning fixtures cannot be universally compatible with various hinge models, resulting in the need to configure various positioning fixtures for the production of different hinge models. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology, at least to a certain extent, the technical problems in the related technology, and to provide a solution to the problem that the existing universal automated welding equipment for temples and hinges cannot stabilize the voltage of temples, silver sheets and hinges, and cannot achieve universality.

[0006] A universal automated welding equipment for stabilizing the pressure of eyeglass temples and hinges includes a frame, on which a welding machine with an induction welding head, a vibratory feeder with a conveying track for conveying hinges, and a positioning column for positioning eyeglass temples are provided. The equipment is characterized in that the frame is further provided with a clamping device for clamping and placing the hinges on the eyeglass temples. The clamping device includes a clamping device and a multi-axis module for driving the clamping device to move in multiple axes; the clamping device includes a protective sleeve, a clamping plate fixed at the lower end of the protective sleeve, a pressing cylinder provided in the protective sleeve, a pressing block connected to the output end of the pressing cylinder, and a pressing needle provided on the pressing block with a certain elasticity; the bottom of the clamping plate is provided with a limiting notch for the hinge part to fall into, and a baffle that blocks the hinge side is provided on one side of the clamping plate; When the clamping cylinder drives the hinge to clamp, the pressure pin approaches and passes through the notch to abut against the hinge, thereby achieving clamping; when the clamping cylinder drives the hinge to release, the pressure pin moves away from and separates from the hinge, thereby achieving release.

[0007] Furthermore, the multi-axis module includes a Y-axis module and a Z-axis module. The Y-axis module includes a Y-moving group and a Y-fixed group mounted on the frame. The Z-axis module includes a Z-moving group and a Z-fixed group fixed to the Y-moving group.

[0008] Furthermore, the clamping device also includes a welding buffer device, which includes a horizontal plate fixed on the Z-moving group, a "T"-shaped post passing through the horizontal plate, one end of the "T"-shaped post being limited to the upper surface of the horizontal plate, and the other end being connected to an adjusting plate, the adjusting plate being fixed on the protective sleeve, and a spring being fitted over the "T"-shaped post, one end of the spring abutting against the adjusting plate, and the other end abutting against the lower surface of the horizontal plate. The sheath is slidably engaged with the Z-moving group; The welding buffer device also includes a first buffer fixed on the Z fixed group and a first stop post on the Z moving group. When welding and placing the workpiece, the Z-axis module drives the clamping plate to move down, and the first buffer abuts against and buffers the first stop post.

[0009] Furthermore, the pressure needle is made of a thin metal rod. After the thin metal rod is folded in half, one end is bent into a hook with a certain elasticity, and the other end is fixed to the pressure block by the first screw.

[0010] Furthermore, the clamping device also includes a pressure needle adjustment device, which includes a step and an adjustment hole on the pressure block. The adjustment hole is threadedly connected to an adjustment screw, and an adjustment nut is threadedly connected to the adjustment screw. The adjustment nut is limited to the step surface of the step, and one end of the adjustment screw abuts against the clamping plate. Rotating the adjustment screw realizes the back-and-forth movement of the pressure needle on the pressure block.

[0011] Furthermore, the clamping device also includes a front and rear centering mechanism, which includes a second oblong hole in the sheath, a second screw hole on the housing of the clamping cylinder, and a second adjusting screw. The second adjusting screw passes through the second oblong hole and the second screw hole in the sheath, and adjusting the position of the second adjusting screw enables the pressure needle connected to the clamping cylinder to move back and forth.

[0012] Furthermore, it also includes a clamping buffer device, which includes a second buffer on the Y fixed group and a second stop on the Z moving group. When clamping the hinge, the Z-axis module drives the clamping plate to move downward, and the second buffer abuts against and buffers the second stop.

[0013] Furthermore, the horizontal position of the moving device is higher than the horizontal position of the positioning post, and the distance between the first buffer and the first stop post is greater than the distance between the second buffer and the second stop post.

[0014] Furthermore, it also includes a moving device for loading and moving the hinge on the conveying track. The moving device includes a moving plate slidably mounted on the frame and a moving cylinder mounted on the frame and driving the moving plate to reciprocate. The moving plate is provided with a step, and a longitudinal slider and a transverse slider are movably mounted on the bottom surface of the step. The longitudinal slider, the transverse slider, and the side of the step together form a positioning port. In the initial state, the outlet of the conveying track is aligned with the positioning port.

[0015] Furthermore, the induction welding head is fitted over the positioning post to heat the temple and hinge on the positioning post.

[0016] The main technical effects of this utility model are reflected in the following aspects: 1: This utility model adopts a clamping plate with a limiting notch. The bottom side of the clamping plate is provided with a baffle for limiting the hinge side. The pressure needle is made of a thin metal rod. After the thin metal rod is folded in half, one end (continuous end) is bent into a hook with a certain elasticity. The hook can easily pass through the notch to abut against the other side of the hinge. Because the hook is made of a continuous end, it is not easy to scratch the hinge. The other end (discontinuous end) is fixed to the pressure block by the first screw to realize the clamping and centering of the hinge. It has low cost and simple structure. In conjunction with the pressure needle adjustment device, rotating the adjusting screw realizes the forward and backward movement of the pressure needle on the pressure block, thereby realizing the forward and backward centering of hinges of various thicknesses, making the clamping force more stable. At the same time, combined with the forward and backward centering mechanism, it realizes the forward and backward centering of hinges of various models, ensuring the stability of the clamping force.

[0017] 2. When the multi-axis module drives the clamping plate down, if the product is thick, the pressure is relatively large and tight. The sheath will move upward slightly, and the spring provides upward force relief to reduce the pressure. When the multi-axis module drives the clamping plate to reset, the spring opens, allowing the sheath to return to its original position. During the welding of smooth products such as temples and hinges, it can position the most suitable contact, ensuring that the welded surface is free of any scratches. This is something that cannot be achieved manually. Through the design of the above-mentioned welding buffer device, stable pressure is maintained between the temple and the hinge, ensuring the welding effect is optimal. Attached Figure Description

[0026] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown: A universal automated welding equipment for stabilizing the pressure of eyeglass temples and hinges includes a frame 1, on which a welding machine 12 with an induction welding head 11, a vibratory feeder 14 with a conveying track 13 for conveying hinges, and a positioning post 15 for positioning eyeglass temples are provided. The equipment is characterized in that the frame 1 is also provided with a clamping device for clamping and placing the hinges on the eyeglass temples. The welding machine 12 is a high-frequency electric welding machine, and the vibratory plate 14 is a vibratory plate with direct vibration.

[0029] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown: The clamping device includes a clamping device and a multi-axis module 21 for driving the clamping device to move in multiple axes; the clamping device includes a protective sleeve 22, a clamping plate 23 fixed at the lower end of the protective sleeve 22, a pressing cylinder 24 disposed in the protective sleeve 22, a pressing block 25 connected to the output end of the pressing cylinder 24, and a pressing needle 26 disposed on the pressing block 25 and having a certain elasticity; the bottom of the clamping plate 23 is provided with a limiting notch 27 for the hinge part to fall into, and a baffle 28 is provided on one side of the clamping plate 23 to block the hinge side; When the clamping cylinder 24 drives the clamping hinge, the pressure pin 26 approaches and passes through the notch 28 to abut against the other side of the hinge, thereby achieving clamping; when the clamping cylinder 24 drives the release of the hinge, the pressure pin 26 moves away from and separates from the hinge, thereby achieving release.

[0030] Initially, the moving device sends the hinge to be processed directly below the limiting notch 27. The multi-axis module 21 drives the clamping plate 23 down to make the hinge sink into the limiting notch 27. Of course, the limiting notch 27 is adapted to the upper surface of the hinge. At this time, the clamping cylinder 24 drives the pressure pin 26 to press the hinge, thereby clamping the hinge.

[0031] The pressure pin 26, which has a certain degree of elasticity, prevents the smooth surface of the hinge from being scratched.

[0032] The clamp structure of this utility model is simple and reasonable, and it is suitable for hinges of various sizes and models.

[0033] like Figure 1 and Figure 2 As shown: The multi-axis module 21 includes a Y-axis module and a Z-axis module. The Y-axis module includes a Y-moving group and a Y-fixed group mounted on the frame 1. The Z-axis module includes a Z-moving group and a Z-fixed group fixed to the Y-moving group.

[0034] Among them, the multi-axis module 21 is an existing 2-axis or 3-axis module. In this embodiment, a 2-axis module is used. The fixed end of the Y-axis module is called the Y fixed group, and the moving end of the Y-axis module is called the Y moving group. The fixed end of the Z-axis module is called the Z fixed group, and the moving end of the Z-axis module is called the Z moving group.

[0035] like Figure 3 and Figure 4 As shown: The clamping device also includes a welding buffer device, which includes a horizontal plate 29 fixed on the Z-moving group. A "T"-shaped post 30 is inserted through the horizontal plate 29. One end of the "T"-shaped post 30 is limited to the upper surface of the horizontal plate 29, and the other end is connected to an adjusting plate 31. The adjusting plate 31 is fixed on the protective sleeve 22. A spring 301 is installed on the outer sleeve of the "T"-shaped post 30. One end of the spring 301 abuts against the adjusting plate 31, and the other end abuts against the lower surface of the horizontal plate 29. If a guide sleeve fixed on the horizontal plate 29 is provided outside the "T"-shaped post 30, the other end of the spring 301 can abut against the guide sleeve. The sheath 22 is slidably engaged with the Z-moving group; With the above design, when the multi-axis module 21 drives the clamping plate 23 down, if the product is thick, the pressure is relatively large and tight, and the sheath 22 will move up a little. The spring 301 provides upward force relief to reduce the pressure. When the multi-axis module 21 drives the clamping plate 23 to reset, the spring 301 springs open, allowing the sheath 22 to reset.

[0036] like Figure 2 As shown: The welding buffer device also includes a first buffer 32 fixed on the Z fixed group and a first stop post 33 provided on the Z moving group. When welding and placing the workpiece, the Z axis module drives the clamping plate 23 to move down, and the first buffer 32 abuts against and buffers the first stop post 33.

[0037] Through the above design, during the welding of smooth products such as mirror temples and hinges, it can position the most suitable contact, so that the welded surface is free of any scratches, which is something that cannot be done manually.

[0038] The design of the above-mentioned welding buffer device ensures stable pressure between the temple and the hinge, thus guaranteeing the welding effect.

[0039] like Figure 6 As shown: The pressure needle 26 is made of a thin metal rod. After the thin metal rod is folded in half, one end is bent into a hook 261 with a certain elasticity. The hook 261 can easily pass through the notch 28, and the other end is fixed to the pressure block 25 by the first screw.

[0040] Through the above design, the pressure needle 26 is inexpensive and has a simple structure.

[0041] like Figure 3 , Figure 4 and Figure 6 As shown: The output end of the clamping cylinder 24 is limited to the pressure block 25 by a second screw. The second screw passes through the through hole on the pressure block 25 and is threadedly connected to the threaded hole of the output end of the clamping cylinder 24. The screw is not locked, so that the pressure block 25 can move slightly back and forth relative to the output end of the clamping cylinder 24. The clamping device also includes a pressure pin adjustment device, which includes a step 34 and an adjustment hole 35 on the pressure block 25. The adjustment hole 35 is threadedly connected to an adjustment screw 36. An adjustment nut 37 is threadedly connected to the adjustment screw 36. The adjustment nut 37 is limited to the step surface of the step 34. One end of the adjustment screw 36 abuts against the clamping plate 23. Rotating the adjustment screw 36 realizes the back and forth movement of the pressure pin 26 on the pressure block 25, thereby realizing the adjustment of the front and back centering of various types of hinges.

[0042] With the above design, when switching between different hinge models, if switching from a thick model to a thin model, the center of gravity of the hinge moves forward. Then, rotating the adjusting screw 36 will move the pressure pin 26 on the pressure block 25 forward to press the hinge tightly. Conversely, rotating the adjusting screw 36 will move the pressure pin 26 on the pressure block 25 backward to prevent the hinge from being pressed too tightly. like Figure 4 As shown: The clamping device also includes a fixing mechanism and a front and rear centering mechanism. The fixing mechanism includes a first oblong hole 38 on the adjusting plate 31, a first screw hole 39 on the protective sleeve 22 and a first adjusting screw 40. The first adjusting screw 40 passes through the first oblong hole 38 and the first screw hole 39 to fix the protective sleeve.

[0043] like Figure 4As shown: The front and rear centering mechanism also includes a second oblong hole 41 provided in the protective sleeve 22, a second screw hole 42 provided in the housing of the pressing cylinder 24, and a second adjusting screw 43. The second adjusting screw 43 passes through the second oblong hole 41 and the second screw hole 42 of the protective sleeve 22, and cooperates with the nut. The second adjusting screw 43 fixes the cylinder, and at the same time, the position of the second adjusting screw 43 is adjusted to realize the back and forth movement of the pressing needle 26 connected to the pressing cylinder 24.

[0044] When switching between hinges of different thicknesses, the center of the hinge side changes back and forth. Adjusting the position of the second adjusting screw 43 allows the pressure pin 26 connected to the pressing cylinder 24 to move back and forth.

[0045] like Figure 2 As shown: It also includes a clamping buffer device, which includes a second buffer 51 on the Y fixed group and a second stop post 52 on the Z moving group. When clamping the hinge, the Z axis module drives the clamping plate 23 to move down, and the second buffer 51 abuts against and buffers the second stop post 52.

[0046] During the material handling process, avoid direct contact with the bottom to prevent excessive pressure from damaging the product.

[0047] like Figure 2 As shown: the horizontal position of the moving device is higher than the horizontal position of the positioning post 15, and the distance between the first buffer 32 and the first stop post 33 is greater than the distance between the second buffer 51 and the second stop post 52.

[0048] The above design prevents the first buffer 32 and the second buffer 51 from working simultaneously.

[0049] like Figure 5 As shown: It also includes a moving device for loading and moving the hinges on the conveying track. The moving device includes a moving plate 61 slidably mounted on the frame 1 and a moving cylinder mounted on the frame 1 that drives the moving plate 61 to reciprocate. The moving plate 61 is provided with a first step 304. The bottom surface of the first step 304 is movably provided with a longitudinal slider 62 and a transverse slider 63. The longitudinal slider 62, the transverse slider 63 and the side of the first step 304 together form a positioning port 64. Through the design of the longitudinal slider 62 and the transverse slider 63, the size of the positioning port 64 can be adjusted when switching hinge models. In the initial state, the outlet of the conveying track is aligned with the positioning port 64, and the vibrating disc 14 conveys a hinge on the conveying track to the positioning port 64.

[0050] like Figure 1 As shown: The induction welding head 11 is sleeved on the positioning post 15 to heat the temple, silver sheet and hinge on the positioning post 15. A horizontal positioning block and a vertical positioning block are also provided next to the positioning post 15 to realize the positioning and placement of the temple.

[0051] Working principle: This utility model also includes a control cabinet, which is electrically connected to each drive source. The manual person places the temple on the positioning block and puts on the silver sheet. The equipment is started, the moving device moves the hinge to the preset position, the clamping device clamps the hinge and transports it to the top of the temple and presses it. The high-frequency spot welding machine works to heat and melt the silver sheet to complete the semi-automatic welding.

[0052] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
