In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will now be further described with reference to the following specific embodiments and drawings.
The bonding head comprises a first movable seat 1 connected with an external movement driving device, a second movable seat 2 connected with the first movable seat 1, a wire cutting device 6 fixedly connected with the first movable seat 1, a wire pressing device 5 connected with the second movable seat 2 and a wire supplying device 7. During welding, the wire supply device 7 conveys welding wires to a welding part along with the welding moving direction of the bonding head, and the wire pressing device 5 applies pressure to the welding wires conveyed by the wire supply device 7, so that the welding wires are attached to the part to be welded, and the welding is convenient.
The outer moving driving device is provided with a telescopic device which stretches along the force applying direction of the wire pressing device 5 and a welding moving device which drives the telescopic device and the bonding head to move in a two-dimensional plane perpendicular to the stretching direction of the telescopic device, namely the outer moving driving device can drive the bonding head to move in the three-dimensional direction. Generally, the bonding head is arranged in a vertical direction, as shown in fig. 2, the welding position is located below the bonding head, and thus, the force application direction of the wire pressing device 5 is vertically downward, so that during welding, the driving device is moved outwards to drive the bonding head to move up and down at first, so as to reach the welding position and apply pressure to the welding wire, so that the welding wire is attached to the welding position, and then the welding wire is moved in a horizontal plane, so that the welding wire is welded on the welding position. The external movement driving device is any structure capable of satisfying the three-dimensional direction movement in the present disclosure in the prior art, for example, the telescoping device includes but is not limited to a cylinder assembly, an oil cylinder assembly, a transmission screw assembly, a linear motor assembly, and the like, the welding moving device includes but is not limited to a transmission screw assembly, a wire motor assembly, a cylinder assembly, an oil cylinder assembly, and the like, and the external movement driving device is not a key point of protection in the present disclosure, and will not be described in detail here.
Based on the above description, during welding, the pressure of the wire pressing device 5 on the bonding head to the welding wire is mainly provided by the telescopic device of the outer moving driving device, the telescopic device changes the pressure applied to the welding wire by the wire pressing device on the bonding head through the telescopic length, but when the wire pressing device 5 presses the welding wire to the welding part, the stroke of the telescopic device of the outer moving driving device is fixed, and the wire pressing device cannot move any more, so that the pressure of the wire pressing device 5 to the welding wire is limited.
In order to solve the problem that the wire pressing force is limited, the technical scheme of the utility model is provided, on the basis of the scheme, the elastic part 4 which is always in a compression state is added on the second movable seat 2. Namely, the bonding head applied to the wire bonding equipment of the technical scheme comprises a first movable seat 1 connected with an external movable driving device, a second movable seat 2 connected with the first movable seat 1, a wire cutting device 6 fixedly connected with the first movable seat 1, and a wire pressing device 5 and a wire supplying device 7 connected with the second movable seat 2. The pressing device further comprises an elastic piece 4 which is arranged between the second moving seat and the first moving seat and is always in a compression state, and the elastic piece 4 pushes the second moving seat 2 to move along the force application direction of the line pressing device 5. The compression direction of the elastic piece 4 is consistent with the force application direction of the line pressing device 5. The first movable seat 1 and the second movable seat 2 have the same moving direction and the same extending direction as the elastic member 4.
An elastic piece 4 which is always in a compressed state is arranged between the first movable seat 1 and the second movable seat 2, and the first movable seat 1 is limited and cannot move autonomously under the action of an external movement driving device, namely the first movable seat 1 cannot move under the pushing of the elastic restoring force of the elastic piece 4. Therefore, the elastic element 4 can only push the second movable seat 2 to drive the wire pressing device 5 to apply pressure to the wire. That is, as shown in fig. 4, the elastic member 4 pushes the second movable base 2 and the wire pressing device 5 to move downward, and applies pressure to the welding wire below the wire pressing device 5, so that the welding wire fits the welding position.
Based on the above technical solution, the pressure applied by the elastic element 4 to the second movable seat 2 is in direct proportion to the length of the second movable seat that is compressed and deformed, that is, the greater the compression amount of the elastic element by the first movable seat and the second movable seat is, the greater the elastic pressure applied by the elastic element to the second movable seat is. When the wire pressing device works, the external movement driving device drives the bonding head to move downwards integrally, so that the wire pressing device 5 presses the welding wire. At this moment, after the wire pressing device 5 presses the welding wire, in the process that the expansion device of the external movement driving device drives the bonding head to move downwards, the expansion device drives the first moving seat to continue to move downwards, the second moving seat can move upwards under the prevention of the welding wire and the welding part, the second moving seat moves upwards and downwards to compress the elastic piece, the larger the vertical movement distance of the second moving seat is, the larger the compressed amount of the elastic piece is, and the larger the pressure from the elastic piece 4 on the second moving seat is relatively. Since the pressure applied by the elastic element to the second movable seat is related to the deformation of the second movable seat, the overall pressure applied by the second movable seat is variable, i.e. the pressure applied by the wire pressing device 5 to the welding wire is variable. This scheme is through setting up the elastic component promptly for compare in prior art, the pressure range that the welding wire obtained is bigger, and stability is better, improves the bonding quality. Meanwhile, when the telescopic device drives the bonding head to wholly press the welding wire downwards, the second movable seat can move upwards due to the arrangement of the elastic piece, so that the problem that the pressure provided by the bonding head to the welding wire is greater than the maximum extreme value is effectively solved, and the problem that the bonding head damages the welding wire is solved.
In this technical solution, the bond head is further connected with an inner movement driving device 3 on the second movable base 2, the inner movement driving device 3 includes a fixing portion 31 and a moving portion 32, the fixing portion 31 is fixedly connected with the first movable base 1, and the moving portion 32 is connected with the second movable base 2. When the inner moving driving device 3 works, the fixed portion 31 is fixed with the first moving seat 1 and keeps a fixed state, the moving portion 32 drives the second moving seat 2 to move, and the moving direction of the second moving seat 2 is parallel to the compressing direction of the elastic element 4. As shown in fig. 3, the moving part 32 drives the second moving seat 2 to move downward, that is, when the wire pressing device 5 presses the wire, the pushing force of the moving part 32 on the inner moving driving device 3 is also applied, and the pressing force is also applied by the weight of the second moving device 2.
