Description

Technical Field

[0001] This application relates to the technical field of welding equipment, and in particular to a low-energy wire bonding machine. Background Technology

[0002] A wire welding machine is a device used for welding metal wires. Its working principle involves heating the metal wire with an electric current to its melting point, and then using a pressure device to press the molten metal wire onto the workpiece surface, forming a uniform weld. Wire welding machines are characterized by high processing efficiency and low labor costs.

[0003] In related technologies, commonly used wire bonding machines generally include a frame and positive and negative welding heads, a first clamping block, and a second clamping block mounted on the frame. The positive and negative welding heads are located on the upper and lower sides of the wire to be welded, respectively, while the first and second clamping blocks are located on the left and right sides of the wire to be welded, respectively. The first and second clamping blocks are used to hold the wire to be welded and are usually made of stainless steel. The positive and negative welding heads are used to pass current through the wire to heat it. During the wire processing, the first and second clamping blocks are first adjusted to clamp the wire. Then, the positive and negative welding heads are energized and press the wire, raising its temperature to the melting point, thus welding the wire into a weld square.

[0004] However, during the operation of the above-mentioned wire bonding machine, since both the first and second clamping blocks are made of conductive stainless steel, the current will flow to the first and second clamping blocks during welding, causing current shunting. The current passing through the wire is insufficient, and the wire cannot reach the melting temperature, resulting in incomplete wire welding. To achieve a better wire welding effect, the current flowing through the positive and negative welding heads must be increased, which leads to high energy consumption of the wire bonding machine. Therefore, it needs to be improved. Utility Model Content

[0005] In order to reduce energy consumption and improve welding strength, this application provides a low-energy wire bonding machine.

[0006] The low-energy wire bonding machine provided in this application adopts the following technical solution:

[0007] A low-energy wire bonding machine includes a frame and a positive electrode welding head, a negative electrode welding head, a first clamping block, and a second clamping block disposed on the frame. The positive electrode welding head and the negative electrode welding head are respectively disposed on both sides of the wire to be bonded along the vertical direction, and the first clamping block and the second clamping block are respectively disposed on both sides of the wire to be bonded along the horizontal direction. The frame is provided with a drive mechanism for controlling the positive electrode welding head to move closer to or away from the negative electrode welding head, and an adjustment mechanism for controlling the first clamping block to move closer to or away from the second clamping block. The first clamping block and the second clamping block are made of silicon nitride material, and the wire to be bonded can be clamped between the positive electrode welding head, the negative electrode welding head, the first clamping block, and the second clamping block.

[0008] By adopting the above technical solution, when welding wire, compared with using stainless steel to make the first and second clamping blocks, silicon nitride has better insulation properties, making it less likely for the first and second clamping blocks to divert the current flowing in the wire to be welded. This results in a larger current flowing in the wire, allowing the wire to reach the melting temperature. The wire welding machine has low energy consumption, and silicon nitride has greater hardness and wear resistance than stainless steel, resulting in more thorough wire welding and a longer service life for the wire welding machine.

[0009] Optionally, the driving mechanism includes a positive electrode base and a driving cylinder for driving the positive electrode base to move closer to or further away from the negative electrode welding head, wherein the positive electrode welding head is detachably connected to the positive electrode base.

[0010] By adopting the above technical solution, after the positive and negative welding heads are energized, the drive cylinder automatically pushes the positive electrode holder closer to the negative welding head, causing the positive welding head to contact and press the wire to be welded, thereby energizing the wire and welding it into a weld square, which is convenient to operate. After the wire welding is completed, the drive cylinder can drive the positive electrode holder to move away from the negative welding head, making it easier to place the wire to be welded for the next welding.

[0011] Optionally, the frame is provided with a negative electrode base, and the negative electrode welding head is detachably connected to the negative electrode base. Both the positive electrode base and the negative electrode base include a base and a fixing plate detachably disposed on one side of the base. The side walls of the base and the fixing plate that are close to each other are provided with fixing grooves. The positive electrode welding head is engaged in the fixing groove of the positive electrode base, and the negative electrode welding head is engaged in the fixing groove of the negative electrode base.

[0012] By adopting the above technical solution, when the positive electrode welding head and the negative electrode welding head are worn, the positive electrode welding head can be removed from the positive electrode holder and the negative electrode welding head can be removed from the negative electrode holder. Then, a new positive electrode welding head or negative electrode welding head can be installed in the corresponding fixing slot, making replacement convenient.

[0013] Optionally, the base is provided with mounting screw holes, and the fixing plate is provided with connecting screw holes that communicate with the mounting screw holes. A connecting bolt is threaded into both the mounting screw holes and the connecting screw holes.

[0014] By adopting the above technical solution, when welding wires of different sizes, the width of the fixing slot can be adjusted by adjusting the length of the threaded connection between the connecting bolt and the base. This allows the fixing slot to accommodate positive and negative welding heads of different sizes. Finally, tightening the connecting bolt secures the positive and negative welding heads in the fixing slot, enabling the welding of wires of different sizes. This design allows the same wire welding machine to weld wires of different sizes, making the machine flexible in its use.

[0015] Optionally, the adjustment mechanism includes a mounting base fixedly mounted on the frame, a slidable push block and a first slider mounted on the mounting base, and a power component for controlling the horizontal movement of the slid push block. The first clamping block is detachably connected to the first slider. The first slider has a guide slope on its side wall near the slid push block, and the slid push block has a guide slope on its side wall near the first slider for engaging with the guide slope. The mounting base has a sliding groove for engaging with the first slider and a movable groove for engaging with the slid push block. When the slid push block is controlled by the power component to move away from the power component, the guide slope will contact the guide slope and push the first slider and the first clamping block towards the side near the second clamping block.

[0016] By adopting the above technical solution, when welding wire, the wire to be welded is first placed between the first clamping block and the second clamping block. Then, the power component can push the inclined push block to slide in the sliding groove. The guide inclined surface on the first slider and the guide inclined surface on the inclined push block cooperate with each other, so that the first clamping block moves closer to the second clamping block, thereby enabling the first clamping block and the second clamping block to clamp the wire, which facilitates the welding of the wire.

[0017] Optionally, the power component includes a push cylinder mounted on the frame and a push rod connected to the piston rod of the push cylinder. The extension and retraction direction of the piston rod of the push cylinder is parallel to the extension direction of the movable groove, and the push rod is fixedly connected to the inclined push block.

[0018] By adopting the above technical solution, when it is necessary to clamp the wire, simply operate the push cylinder to make the push rod drive the inclined push block to move in the movable groove, thereby causing the inclined push block to drive the first slider to move closer to the second clamping block. The operation is simple.

[0019] Optionally, the adjustment mechanism further includes a reset block disposed on the first slider and a reset spring abutting between the reset block and the mounting base, the reset spring being capable of driving the first slider to move away from the second clamping block.

[0020] By adopting the above technical solution, after the wire is welded, the push cylinder will drive the inclined push block to move away from the first slider. At this time, the return spring can push the first slider away from the second clamping block, so that the distance between the first clamping block and the second clamping block increases. The welded wire can be taken out from the first clamping block and the second clamping block, which is convenient for the next welding.

[0021] Optionally, the frame is provided with a positioning seat for installing the second clamping block, the positioning seat is provided with a positioning block, the first slider is provided with a fastening block, and pressure plates are detachably provided on both the positioning block and the fastening block. A first fastening groove is formed between the pressure plate and the fastening block, and a second fastening groove is formed between the pressure plate and the positioning block. The first clamping block is disposed in the first fastening groove, and the second clamping block is disposed in the second fastening groove.

[0022] By adopting the above technical solution, when the first and second clamping blocks are worn, the pressure plate can be removed first, then the worn first and second clamping blocks can be taken out, and then a new first clamping block can be placed into the first fastening groove and a new second clamping block into the second fastening groove. Finally, the pressure plate can be installed to complete the replacement. This design allows the first and second clamping blocks to be replaced individually without replacing the entire wire bonding machine, thus extending the service life of the wire bonding machine. Furthermore, different sizes of the first or second clamping blocks can be replaced using the above method, enabling the wire bonding machine to weld wires of different sizes, thereby diversifying its application scenarios.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The first and second clamps are made of silicon nitride material with good insulation, which makes it difficult for the first and second clamps to divert the current flowing in the wire, resulting in more thorough wire welding and lower energy consumption of the wire welding machine.

[0025] 2. When welding wire, the drive cylinder can control the positive welding head to move closer to or away from the negative welding head, the push cylinder can control the first clamping block to move closer to the second clamping block, and the return spring can control the first clamping block to move away from the second clamping block, making the positioning and storage of the wire convenient.

[0026] 3. The positive electrode welding head is detachably mounted on the positive electrode base, and the negative electrode welding head is detachably mounted on the negative electrode base, so that the positive electrode welding head and the negative electrode welding head can be replaced separately after wear, saving resources.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a low-energy wire bonding machine.

[0036] Reference Figure 1 and Figure 2 A low-energy wire bonding machine includes a frame 1 and a positive electrode welding head 2, a negative electrode welding head 3, a first clamping block 4, and a second clamping block 5 detachably mounted on the frame 1. The positive electrode welding head 2 and the negative electrode welding head 3 are respectively positioned on both sides of the wire to be bonded along the vertical direction, and the first clamping block 4 and the second clamping block 5 are respectively positioned on both sides of the wire to be bonded along the horizontal direction. Figure 2 From the perspective of the wire bonding machine, the first clamping block 4 and the second clamping block 5 are respectively located on the left and right sides of the wire to be bonded. When the wire bonding machine is working, the wire to be bonded can be clamped between the positive electrode welding head 2, the negative electrode welding head 3, the first clamping block 4, and the second clamping block 5. In this embodiment, the positive electrode welding head 2 is preferably located directly above the negative electrode welding head 3. In other cases, the positions of the positive electrode welding head 2 and the negative electrode welding head 3 can be interchanged according to customer needs.

[0037] Reference Figure 3 The first clamping block 4 and the second clamping block 5 are made of silicon nitride. Silicon nitride has excellent insulation properties. During wire welding, when current is passed through the conductor, the first clamping block 4 and the second clamping block 5 are less likely to divert the current that should flow into the wire, thus reducing energy waste and resulting in lower energy consumption and more thorough wire welding. Furthermore, silicon nitride has greater hardness and wear resistance than stainless steel, leading to higher wire welding strength.

[0038] Reference Figure 2 and Figure 3The frame 1 is provided with a positive electrode seat 6 for mounting the positive electrode welding head 2, a negative electrode seat 7 for mounting the negative electrode welding head 3, a first slider 8 for mounting the first clamping block 4, and a positioning seat 9 for mounting the second clamping block 5. The positive electrode seat 6 and the negative electrode seat 7 each include a base 61 and a fixing plate 62 detachably disposed on one side of the base 61. The base 61 has mounting screw holes (not shown in the figure), and the fixing plate 62 has connecting screw holes (not shown in the figure). The mounting screw holes and the connecting screw holes are interconnected and both have connecting bolts 63 passing through them. In this embodiment, the number of connecting bolts 63 on each fixing plate 62 is preferably 4. In other cases, the specific number can be selected according to customer needs.

[0039] Reference Figure 3 Both the base 61 and the fixing plate 62 have fixing grooves 64 on their adjacent sides. The positive electrode welding head 2 is engaged in the fixing groove 64 of the positive electrode base 6, and the negative electrode welding head 3 is engaged in the fixing groove 64 of the negative electrode base 7. A fastening block 81 is fixed on the first slider 8, and a positioning block 91 is fixed on the positioning base 9. Both the fastening block 81 and the positioning block 91 are detachably equipped with pressure plates 82. A first fastening groove 83 is formed between the pressure plate 82 and the fastening block 81, and a second fastening groove 92 is formed between the pressure plate 82 and the positioning block 91. A first clamping block 4 is disposed in the first fastening groove 83, and a second clamping block 5 is disposed in the second fastening groove 92.

[0040] Reference Figure 3 With the above setup, when the positive electrode welding head 2, negative electrode welding head 3, first clamping block 4, and second clamping block 5 wear out during use, they can be removed and replaced with new welding heads or clamping blocks, saving resources. Similarly, welding heads or clamping blocks of different sizes can also be replaced in the above manner, enabling the wire bonding machine to weld wires of different sizes, thus making the wire bonding machine flexible and versatile in its use.

[0041] Reference Figure 2 The frame 1 is equipped with a drive mechanism 10 for controlling the movement of the positive electrode welding head 2 towards or away from the negative electrode welding head 3. The drive mechanism 10 includes a drive cylinder 101 and a positive electrode seat 6 connected to the output shaft of the drive cylinder 101. The piston rod of the drive cylinder 101 faces downward and is fixedly connected to the positive electrode seat 6. With the above configuration, the drive cylinder 101 can push the positive electrode seat 6 towards or away from the negative electrode welding head 3, so that the positive electrode welding head 2 and the negative electrode welding head 3 can automatically extrude the wire, making welding convenient.

[0042] Reference Figure 4 and Figure 5The frame 1 is equipped with an adjustment mechanism 11 for controlling the movement of the first clamping block 4 toward or away from the second clamping block 5. The adjustment mechanism 11 includes a mounting base 111 fixedly mounted on the frame 1, a slidable push block 114 and a first slider 8 slidably mounted on the mounting base 111, a power component 116 for controlling the horizontal movement of the slid push block 114, a reset block 119 fixedly mounted on the first slider 8, and a reset spring 120 abutting between the reset block 119 and the mounting base 111. The mounting base 111 has a limiting hole 121 for one end of the reset spring 120 to extend into, and the reset spring 120 is fixedly connected to the wall of the limiting hole 121. The power component 116 includes a push cylinder 117 whose cylinder is fixedly mounted on the frame 1, a push rod 118 fixedly connected to the piston rod of the push cylinder 117, and the slid push block 114 fixedly connected to the push rod 118.

[0043] Reference Figure 4 The first slider 8 has a guide slope 84 on its side wall near the inclined push block 114, and the inclined push block 114 has a guide slope 115 on its side wall near the first slider 8 that cooperates with the guide slope 84. The mounting base 111 has a sliding groove 112 that slides with the first slider 8 and a movable groove 113 that slides with the inclined push block 114. The extending direction of the sliding groove 112 is perpendicular to the extending direction of the movable groove 113. The sliding groove 112 can restrict the sliding direction of the first slider 8, and the movable groove 113 can restrict the sliding direction of the inclined push block 114.

[0044] Reference Figure 4 and Figure 5 With the above configuration, when the push cylinder 117 pushes the inclined push block 114 away from the push cylinder 117, the guide inclined surface 115 will contact the guide inclined surface 84. At this time, the inclined push block 114 will push the first slider 8 towards the second clamping block 5, thereby reducing the distance between the first clamping block 4 and the second clamping block 5, so as to clamp the wire to be welded. After welding is completed, the return spring 120 can drive the first slider 8 to return to its original position away from the second clamping block 5, which is convenient for the next welding and the reset is convenient.

[0045] The implementation principle of a low-energy wire bonding machine according to an embodiment of this application is as follows: When welding wires, the wire to be welded is first placed between the first clamping block 4 and the second clamping block 5. Then, the inclined push block 114 is moved away from the pushing cylinder 117 by the pushing cylinder 117, so that the first clamping block 4 and the second clamping block 5 clamp the wire. Then, current is passed through the positive welding head 2 and the negative welding head 3, and the positive welding head 2 is pushed towards the negative welding head 3 by the driving cylinder 101, and the wire to be welded is squeezed, thereby welding the wire into a weld square. After welding is completed, the return spring 120 will push the first slider 8 away from the second clamping block 5 so as to remove the welded wire for the next welding.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
