Referring to fig. 1-3, a wire bonding apparatus 100 according to an embodiment of the present application is used for bonding a head end of a wire 200, where the wire bonding apparatus 100 includes a base 10, a clamping mechanism 20, and a bonding tool 30.

The clamping mechanism 20 is connected with the seat body 10, the clamping mechanism 20 comprises a first driving mechanism 21 and a plurality of clamping assemblies 22, one end of each clamping assembly 22 along a first direction A is detachably connected with the first driving mechanism 21, the other end of each clamping assembly 22 along the first direction A is provided with a mounting hole penetrating through the clamping assembly 22 along a second direction B, the mounting hole is used for being penetrated by the head end of the guide wire 200, and the radial sizes of the mounting holes of different clamping assemblies 22 are different. Each clamping assembly 22 comprises two clamping pieces 221 oppositely arranged along the third direction C, the two clamping pieces 221 of the same clamping assembly 22 are butted to form a mounting hole, and the first driving mechanism 21 is used for driving the two clamping pieces 221 connected with the first driving mechanism 21 to be close to or far away from each other along the third direction C. The welding tool 30 is connected to the base 10, and the welding tool 30 is disposed at a distance from the clamping assembly 22 in the second direction B, the welding tool 30 being used to weld the end of the head end of the guide wire 200. The first direction A, the second direction B and the third direction C are perpendicular to each other.

In the above-mentioned wire welding device 100, by providing the clamping mechanism 20, the clamping mechanism 20 includes the first driving mechanism 21 and the clamping assembly 22, so that the clamping assembly 22 clamps and fixes the head end of the wire 200 by penetrating the head end of the wire 200 into the mounting hole of the clamping assembly 22. And since the clamping assembly 22 includes two clamping members 221 disposed opposite to each other along the third direction C, and the two clamping members 221 of the same clamping assembly 22 are abutted to form a mounting hole, the first driving mechanism 21 is used for driving the two clamping members 221 connected with the first driving mechanism to approach or separate from each other along the third direction C, so that the two clamping members 221 connected with the first driving mechanism 21 can clamp or loosen the head end of the guide wire 200, so as to respectively realize the fixed connection or separation of the clamping assembly 22 and the guide wire 200. In addition, by providing the clamping assembly 22 to include a plurality of clamping assemblies 22, and having different radial dimensions of the mounting holes of the different clamping assemblies 22, the mounting holes of the different clamping assemblies 22 can be used for threading guide wires 200 of different thicknesses, respectively. And each clamping assembly 22 is detachably connected with the first driving mechanism 21, so that a plurality of clamping assemblies 22 can be respectively and interchangeably connected with the first driving mechanism 21, and thus, guide wires 200 with different thicknesses can be respectively fixed relative to the base body 10 through the corresponding clamping assemblies 22, and the end parts of the head ends of the guide wires 200 can be welded through the welding tool 30. Accordingly, by providing a plurality of clamping assemblies 22 and providing mounting holes of different clamping assemblies 22 having different radial dimensions from one another, the guidewire welding device 100 can be adapted to different thicknesses of the guidewire 200.

In the actual use process, in order to smoothly pass the guide wire 200 through the mounting hole of the corresponding clamping assembly 22, when the guide wire 200 needs to be clamped, the two clamping pieces 221 connected with the first driving mechanism 21 are spaced from each other along the third direction C, and then the head end of the guide wire 200 passes through the mounting hole from the clamping assembly 22 along the second direction B and away from one side of the welding tool 30 through operation, so as to extend from the other side of the clamping assembly 22. Then, the first driving mechanism 21 is driven to approach each other along the third direction C until the two clamping members 221 connected to the first driving mechanism 21 are connected to each other and butt-jointed to form a mounting hole, thereby clamping the guide wire 200, and at this time, the guide wire 200 is clamped and fixed by the clamping assembly 22, that is, the guide wire 200 is fixed relative to the base 10. And then the end of the head end of the guide wire 200 is welded by the welding tool 30, so that the end of the head end of the guide wire 200 is in a ball shape.

Fig. 4 is a schematic view of the construction of the bonding tool and the third driving mechanism according to the embodiment shown in fig. 1.

To facilitate welding of the end of the head end of the guidewire 200 by the welding mechanism, in some embodiments, as shown in fig. 1 and 4, the guidewire welding device 100 further includes a third drive mechanism 80 disposed on the base 10, the third drive mechanism 80 being coupled to the welding tool 30, the third drive mechanism 80 being configured to drive the welding tool 30 to move relative to the clamp assembly 22 in the second direction B. In this way, the welding tool 30 can approach the clamping assembly 22 along the second direction B under the driving of the third driving mechanism 80 until a first preset distance is provided between the welding tool 30 and the end of the head end of the guide wire 200 along the second direction B, so as to finish the welding of the welding tool 30 to the end of the head end of the guide wire 200, and the end of the head end of the guide wire 200 is in a ball shape. After the welding is finished, the welding tool 30 is driven by the third driving mechanism 80 to be far away from the clamping assembly 22 along the second direction B until a second preset distance is formed between the welding tool 30 and the end part of the head end of the guide wire 200 along the second direction B, wherein the second preset distance is greater than the first preset distance, so that the welded guide wire 200 is conveniently taken down from the clamping assembly 22, the unwelded guide wire 200 is conveniently arranged on the clamping assembly 22, and the clamping assembly 22 connected with the first driving mechanism 21 is conveniently replaced.

In some embodiments, the wire bonding apparatus 100 further includes a controller (not shown) electrically coupled to the third drive mechanism 80 for controlling the output of the third drive mechanism 80 to control the third drive mechanism 80 to drive the bonding tool 30 in the second direction B relative to the clamping assembly 22.

To enable first drive mechanism 21 to drive two jaws 212 toward and away from each other in third direction C, in some embodiments, as shown in connection with fig. 2-3, first drive mechanism 21 includes a first drive member 211 coupled to housing 10 and two jaws 212 coupled to first drive member 211, respectively. Two clamping jaws 212 are opposite to each other in the third direction C and are spaced apart from each other and are connected to clamping members 221 of the same clamping assembly 22 in a one-to-one correspondence, and a first driving member 211 is used to drive two clamping jaws 212 towards or away from each other in the third direction C. In this way, by providing the first driving member 211 to provide the power for moving the two clamping jaws 212 toward or away from each other along the third direction C, by providing the clamping jaws 212 to be connected to the clamping members 221 of the same clamping assembly 22 in a one-to-one correspondence manner, each clamping jaw 212 can be driven by the first driving mechanism 21 to move the clamping member 221 connected thereto along the third direction C, so that the clamping members 221 connected to the other clamping jaw 212 are moved toward or away from each other, thereby achieving the clamping or releasing of the guide wire 200.

During actual use, replacement of clamping assembly 22 coupled to first drive mechanism 21 is accomplished by assembling or disassembling clamping member 221 with a corresponding clamping jaw 212.

In some embodiments, a positioning member (not shown) is provided within each jaw 212, including a sleeve and a resilient member, each extending in the third direction C. One end of sleeve in third direction C is secured within jaw 212 and the other end of sleeve in third direction C is provided with an opening. One end of the elastic member in the third direction C passes through the opening and is connected to the inner wall of the sleeve, and the other end of the elastic member in the third direction C is connected to the clamping member 221. Thus, by providing a positioning member within jaw 212, the positioning member includes a sleeve and an elastic member having one end disposed within the sleeve in a third direction C, such that the other end of the elastic member in the third direction C is capable of telescoping relative to the sleeve under the action of an external force. And because the elastic member is used for being connected with the clamping member 221 along the third direction C at the end far away from the sleeve, the clamping member 221 can compress the elastic member along the third direction C into the sleeve, and because the elastic member has a tendency to recover, the clamping member 221 is subjected to the elastic force of the elastic member along the third direction C and towards the side far away from the sleeve, so that the clamping member 221 is abutted and fastened in the clamping jaw 212 under the elastic force of the elastic member. Therefore, in use, the clamping member 221 is inserted into the corresponding clamping jaw 212 along the first direction a, and the clamping member 221 can push the elastic member to compress in the sleeve along the third direction C, and the clamping member 221 is fixed relative to the clamping jaw 212 under the elastic force of the elastic member, so as to avoid unstable clamping of the guide wire 200 caused by shaking of the clamping member 221 relative to the clamping jaw 212. When the clamping member 221 needs to be replaced, the clamping member 221 is pulled out from the corresponding clamping jaw 212 along the first direction a, and then the clamping member 221 of the other clamping assembly 22 is inserted into the clamping jaw 212, so that the replacement of different clamping assemblies 22 is realized, and the operation of replacing the clamping assemblies 22 is quick and convenient.

In some embodiments, the elastic member includes an abutment member penetrating the opening of the sleeve in the third direction C, and a spring (not shown) connected between the abutment member and an inner wall of the sleeve, the spring being capable of providing an elastic force for moving the abutment member in the third direction C toward a side away from the sleeve, such that an end of the abutment member away from the elastic member in the third direction C abuts against the clamping member 221 to fix the clamping member 221 relative to the clamping jaw 212.

Alternatively, the positioning member may employ a spring plunger.

In the actual use process, the corresponding clamping assembly 22 is determined according to the thickness of the guide wire 200 to be welded, and then the clamping assembly 22 corresponding to the guide wire 200 is mounted on the first driving mechanism 21. The two clamping members 221 of the clamping assembly 22 connected thereto are spaced apart from each other in the third direction C by the first driving mechanism 21 to pass the head end of the guide wire 200 to be welded through the mounting hole, and then the two clamping members 221 connected thereto are brought close to each other in the third direction C by the first driving mechanism 21 until the two clamping members 221 are butted, clamping the guide wire 200 to be welded between the two clamping members 221.

In some embodiments, the controller is electrically connected to the first driving mechanism 21, and the controller is used to control the output of the first driving mechanism 21 to control the two clamping members 221 connected to the first driving mechanism 21 to move closer to or further away from each other along the third direction C. In this way, the controller is provided to control the output of the first driving mechanism 21, thereby improving the degree of automation of the wire bonding apparatus 100.

In some embodiments, as shown in fig. 2-3, the guidewire welding device 100 further includes a stop mechanism 40, the stop mechanism 40 including a second drive mechanism 41 coupled to the housing 10, and a stop member 42 coupled to the second drive mechanism 41. The stop 42 has a first position and a second position spaced apart from each other along the third direction C, and when the stop 42 is in the first position, the stop 42 is located between the bonding tool 30 and the clamping assembly 22 along the second direction B, and when the stop 42 is in the first position, a side of the stop 42 adjacent to the clamping assembly 22 along the second direction B abuts against an end of the head end of the guide wire 200 along the second direction B. The second driving mechanism 41 is used for driving the limiting member 42 to reciprocate between the first position and the second position along the third direction C. In this way, by providing the stopper 42, and the stopper 42 has the first position that can be abutted against the end of the head end of the guide wire 200 along the second direction B, the stopper 42 can position the end of the head end of the guide wire 200 along the second direction B relative to the seat 10, that is, the distance between the end of the head end of the guide wire 200 and the welding tool 30 along the second direction B can be limited by the stopper 42, so that the uniformity of the size of the ball-shaped structure formed by welding the plurality of guide wires 200 can be improved. And through setting up the locating part 42 and having the second position, the locating part 42 can reciprocate between first position and second position under the drive of second actuating mechanism 41, makes the head end of seal wire 200 pass through the locating part 42 after the location, can make the locating part 42 remove from first position to the second position through second actuating mechanism 41 to make the locating part 42 not block between welding tool 30 and clamping assembly 22, in order not to hinder welding tool 30 to the tip of the head end of seal wire 200.

Optionally, the limiting mechanism 40 can move along the second direction B relative to the base 10, so that when the limiting member 42 is located at the first position, the distance between the limiting member 42 and the clamping assembly 22 along the second direction B can be adjusted according to the use requirement, so that the size of the ball-shaped structure formed at the head end of the guide wire 200 can be set according to the use requirement.

Specifically, as shown in fig. 2, the wire welding device 100 includes an adjusting mechanism 90, the adjusting mechanism 90 includes a sliding table 91 connected with the base 10, the second driving mechanism 41 is slidably connected with the sliding table 91 along the second direction B, the adjusting mechanism 90 further includes a fastener 92 penetrating the second driving mechanism 41, and the fastener 92 is used for fixing the second driving mechanism 41 relative to the sliding table 91. In this way, in use, the fixing of the limiting mechanism 40 relative to the base 10 is achieved by tightening or loosening the fastener 92, or the limiting mechanism 40 can slide on the sliding table 91 along the second direction B, so as to adjust the distance between the limiting member 42 and the clamping assembly 22 along the second direction B.

In some embodiments, as shown in fig. 2-3, the wire bonding apparatus 100 further includes a first detection mechanism 50 disposed on the base 10 and electrically connected to the controller, the first detection mechanism 50 is disposed on a side of the clamping assembly 22 away from the bonding tool 30 along the second direction B, and the first detection mechanism 50 is disposed at a distance from the clamping assembly 22 along the second direction B. The first detection mechanism 50 is used for detecting whether the guide wire 200 is arranged in the mounting hole in a penetrating mode, when the guide wire 200 is arranged in the mounting hole in a penetrating mode, the first detection mechanism 50 sends a first signal to the controller, and when the guide wire 200 is not arranged in the mounting hole in a penetrating mode, the first detection mechanism 50 sends a second signal to the controller. The controller is used for controlling the second driving mechanism 41 to drive the limiting piece 42 to move from the first position to the second position when receiving the first signal and the starting signal, and is used for controlling the second driving mechanism 41 to drive the limiting piece 42 to move from the second position to the first position when receiving the second signal. In this way, by setting the first detecting mechanism 50 to detect whether the guide wire 200 is threaded through the mounting hole, after the guide wire 200 is threaded through the mounting hole and receives the start signal, the controller controls the limiting member 42 to move from the first position to the second position, that is, controls the limiting member 42 to withdraw from between the welding tool 30 and the clamping assembly 22 along the third direction C, so that the electric foolproof effect can be achieved. And when the guide wire 200 is not penetrated through the mounting hole, the first detection mechanism 50 sends a second signal to the controller, so that after the guide wire 200 is completely welded and taken out of the mounting hole, the controller controls the second driving mechanism 41 to drive the limiting piece 42 to move from the second position to the first position, and the next guide wire 200 to be welded is limited.

Alternatively, the activation signal may be input to the controller by an operator. For example, a start switch electrically connected to the controller may be provided on the housing 10, and an operator may operate the start switch to cause the controller to receive a start signal.

In the actual use process, the clamping assembly 22 corresponding to the thickness of the guide wire 200 to be welded is first installed on the first driving mechanism 21, the limiting member 42 is at the first position, and the distance between the limiting member 42 and the clamping assembly 22 along the second direction B is adjusted by the adjusting mechanism 90. And the two clamping members 221 connected to the first driving mechanism 21 are spaced apart from each other along the third direction C, and then the end of the head end of the guide wire 200 passes through the space between the two clamping members 221 along the second direction B until the end of the head end of the guide wire 200 abuts against one side of the limiting member 42 near the clamping assembly 22 along the second direction B. At this point the first detection mechanism 50 detects the guidewire 200 and sends a first signal to the controller. When the end of the head end of the guide wire 200 abuts against the limiting member 42, the operator operates the start switch to enable the controller to receive the start signal, and the controller controls the second driving mechanism 41 to enable the limiting member 42 to move from the first position to the second position along the third direction C. The controller then controls the third drive mechanism 80 to drive the bonding tool 30 in the second direction B such that the bonding tool 30 approaches the head end of the guide wire 200 to bond the end of the head end of the guide wire 200.

Alternatively, as shown in fig. 3 and 4, the first detecting mechanism 50 includes a transmitting member 51 and a receiving member 52 arranged at intervals in the third direction C, the transmitting member 51 being configured to transmit a light beam to the receiving member 52, and the receiving member 52 being configured to receive the light beam. The controller is electrically connected to the receiver 52, and the receiver 52 sends a first signal to the controller when the light beam is blocked by the guide wire 200, and the receiver 52 sends a second signal to the controller when the light beam is not blocked by the guide wire 200.

To ensure that the first detection mechanism 50 detects the guide wire 200 passing through the mounting hole, in some embodiments, as shown in fig. 2-3, the guide wire welding device 100 further includes a guide plate 60 disposed on the base 10, where the guide plate 60 is disposed on a side of the first detection mechanism 50 away from the welding tool 30 along the second direction B.
