Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling fixture for an automatic wire welding machine window. Background Art

[0002] Currently, when flat-panel SMT products need to be secured during the automated wire bonding process, they are often secured using a motor-driven window clamp that contacts the product surface. The surface of the carrier strip's sink is typically gold-plated, and using the window clamp can scratch the gold plating. Furthermore, the window clamp fixation method is mostly suitable for metal sinks. However, if the sink is made of a ceramic cavity with a 1mm-thick gold-plated surface, the ceramic has limited resistance, and contact with the motor-driven window clamp can easily lead to ceramic fracture. Utility Model Content

[0003] The purpose of the utility model is to provide a window clamp tooling for an automatic wire welding machine, which can reduce the friction between the surface of the sink and the product components, so that the surface of the sink is not damaged, and can reduce the force applied to the sink during the operation process, and prevent damage to the sink caused by mechanical hard contact.

[0004] The utility model provides a window clamp tooling for an automatic wire welding machine, comprising: a carrier bar, a sink, a window clamp and a spring assembly;

[0005] The sink is a groove on the carrier bar for placing product components;

[0006] The window clip is installed above the carrier strip, and the spring assembly is installed on the window clip. When the window clip moves toward the carrier strip, the spring assembly contacts the edge of the product component and fixes the product component.

[0007] Preferably, the spring assembly includes a connecting piece and a spring;

[0008] The connecting piece is threadedly connected to the window clamp;

[0009] A connecting hole is provided in the middle of the connecting piece, the elastic piece is installed in the connecting hole, and the end of the elastic piece is connected to the connecting piece.

[0010] Further preferably, a side of the elastic piece away from the connecting piece is wrapped with a heat shrink tube.

[0016] Preferably, the cavity of the sink is made of ceramic.

[0017] Preferably, the wall thickness of the cavity of the sink is 1 mm.

[0018] Beneficial effects:

[0019] The technical solution of the present invention drives the window clip to move in the direction of the carrier strip so that the window clip contacts the carrier strip. At this time, the spring assembly on the window clip contacts the edge of the product component placed on the sink groove of the carrier strip, fixing the position of the product component. Thereafter, welding and other actions are performed, which can reduce the friction between the surface of the sink groove and the product component, leaving the surface of the sink groove undamaged, and can reduce the force applied to the sink groove during operation, thereby preventing damage to the sink groove caused by mechanical hard contact.

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0029] like Figures 1 to 3 As shown, the present invention provides a window clamp fixture for an automatic wire welding machine, comprising: a carrier strip 1, a sink 2, a window clamp 3, and a spring assembly 4. The sink 2 is a groove on the carrier strip 1 for accommodating a product component 7. The window clamp 3 is mounted above the carrier strip 1, and the spring assembly 4 is mounted on the window clamp 3. When the window clamp 3 moves toward the carrier strip 1, the spring assembly 4 contacts the edge of the product component 7 and secures the product component 7.

[0030] The technical solution of the present invention drives the window clip 3 to move toward the carrier strip 1, and the spring assembly 4 on the window clip 3 contacts the edge of the product component 7 placed on the sink 2 of the carrier strip 1, fixing the position of the product component 7, and then performing operations such as wire welding. This can reduce the friction between the surface of the sink 2 and the product component 7, leaving the surface of the sink 2 undamaged, and can also reduce the force applied to the sink 2 during operation, preventing damage to the sink 2 caused by mechanical hard contact.

[0031] like Figure 3 As shown, the spring assembly 4 includes a connector and a spring 5, and the connector is threadedly connected to the window clip 3. A connecting hole 8 is provided in the middle of the connector, and the spring 5 is installed in the connecting hole 8, and the end of the spring 5 is connected to the connector.

[0032] like Figure 2 and Figure 3 As shown, there are two springs 5 ​​and they are symmetrically distributed so that the component is evenly stressed. The side of the spring 5 away from the connector is wrapped with a heat shrink tube to prevent the surface of the product component 7 from being scratched.

[0033] The carrier strip 1 is also provided with a slide groove 6, along which the window clip 3 reciprocates horizontally, allowing it to align with the product component 7. The four corners of the connector are threadedly connected to the window clip 3, securing the connector to the window clip 3. The window clip 3 is connected to a drive component. In this embodiment, the drive component is a motor.

[0034] Working process:

[0035] The window clamp 3 is mounted on the machine's robotic arm. The connection hole 8 on the window clamp 3 is slid to align with the product component 7 within the slot 6 of the carrier strip 1. Driven by a motor, the window clamp 3 moves toward the carrier strip 1 until it contacts the strip. It is then lifted back 1 mm (this lift is a correction, allowing for spring force for the spring clip 5). The end of the spring clip 5 is then brought into contact with the edge of the product component 7, securing it before wire bonding and other operations can proceed. The contact area of ​​the spring clip 5 with the product component 7 is wrapped in heat shrink tubing to prevent scratches on the surface of the product component 7. The spring clip 5 securing the product component 7 reduces friction between the surface of the sink 2 and the product component 7 during wire bonding, preventing damage to the surface. In this embodiment, the sink 2 is a combination of a ceramic cavity and a 1 mm thick gold-plated surface. Ceramic has limited strength. Using the spring clip 5 to secure the product component 7 reduces the forces applied to the sink 2 during operation, preventing damage from mechanical contact.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
