Description

Technical Field

[0001] This application belongs to the field of welding equipment technology, and more specifically, relates to a wire welding device. Background Technology

[0002] Wire bonding equipment is a welding device used to perform wire bonding operations on circuit boards. In order to ensure that the welding end of the wire harness can be accurately aligned with the pads on the circuit board, traditional wire bonding equipment usually has multiple cameras. Due to the high flexibility of the wire harness, when the wire clamping device of the wire bonding equipment clamps the wire harness, the exposed part of the wire harness will bend to a certain extent. At this time, it is necessary to take pictures of the welding end of the wire harness from different angles through each camera to obtain a three-dimensional image of the welding end of the wire harness. Then, the three-dimensional image is analyzed and calculated, and the wire clamping device is controlled to drive the wire harness to move to the position of the pad on the circuit board based on the analysis results.

[0003] However, traditional wire bonding equipment requires multiple cameras to work together to align the welding ends of the wire harness with the pads on the circuit board, making the overall structure and control system of the wire bonding equipment very complex, which in turn leads to a significant increase in the production cost of the wire bonding equipment. Summary of the Invention

[0004] The purpose of this application is to provide a wire bonding device to solve the technical problem that the production cost of wire bonding devices is greatly increased because multiple cameras are required to cooperate to align the welding end of the wire harness with the pads of the circuit board.

[0011] Optionally, the first mounting base is provided with a slide rail parallel to the driving direction of the second driving mechanism. The base body is slidably mounted on the slide rail, and a limiting groove extending along the driving direction of the second driving mechanism is opened on the side of the base body away from the first clamping member. The second clamping member is disposed in the limiting groove. The second driving mechanism drives the base body to move away from or towards the guide member through the second clamping member, so that the base body cooperates with the guide member to clamp or release the workpiece to be welded.

[0012] Optionally, the clamping seat further includes an elastic element that abuts against the seat body and the second clamping member. The seat body is provided with a limiting portion that abuts against the guide seat.

[0020] Optionally, the inlet groove has a wire take-up port that extends from one end of the inlet groove to the other end of the inlet groove, and the base can close the wire take-up port when it moves to the inlet member.

[0021] Optionally, the clamping seat further includes a first limiting member and a second limiting member, the first limiting member and the second limiting member being disposed on the seat body with relative separation, and the first limiting member and the second limiting member being located between the first clamping member and the second clamping member.

[0022] Optionally, the chuck assembly includes a second mounting base, a first chuck, and a second chuck. The second mounting base is connected to the power output end of the first drive mechanism. Both the first chuck and the second chuck are mounted on the second mounting base, and the first chuck and the second chuck are arranged sequentially.

[0023] Optionally, the vision device further includes a fill light, which is positioned directly opposite the working end of the camera, and the fill light is a surface light source.

[0024] The wire bonding equipment provided in this application has at least the following advantages: Compared with the prior art, the wire bonding equipment of this application sets an inlet seat on the fixture, and an inlet groove is opened in the inlet part of the inlet seat. The inlet groove includes an inlet section and a straight section. One end of the straight section is connected to the inlet section, and the other end of the straight section is set directly opposite to the pad of the workpiece to be bonded. During the wire bonding operation, the controller controls the chuck assembly to clamp the wire harness. Then, the controller controls the first drive mechanism to drive the chuck assembly to move to the vision device, so that the welding end of the wire harness is facing the working end of the camera. Then, the controller controls the camera to take a picture of the welding end of the wire harness, thereby obtaining a one-dimensional image of the welding end of the wire harness. The controller analyzes and calculates the one-dimensional image to obtain the straight length of the welding end of the wire harness, and then calculates the insertion depth of inserting the welding end of the wire harness into the inlet groove. After that, the controller controls the first drive mechanism to drive the chuck assembly to move to the fixture and insert the welding end of the wire harness into the inlet groove. In the guide section of the inlet groove, the welding end of the wire harness enters the straight section of the guide groove under the guiding action of the guide section. Under the abutment of the inner wall of the straight section, the welding end of the wire harness is gradually straightened, so that the welding end of the wire harness is approximately straight after passing through the guide groove. At this time, the actual insertion depth of the welding end of the wire harness into the guide groove is consistent with the insertion depth obtained by the controller after analyzing and calculating the above one-dimensional image. This allows the controller to control the first drive mechanism to insert the welding end of the wire harness into the guide groove according to its calculated insertion depth, thereby realizing the alignment of the welding end of the wire harness with the pad of the workpiece to be welded. It can be seen that, with the cooperation of the guide component, the above wire bonding equipment only needs to use one camera to realize the alignment operation of the welding end of the wire harness with the pad of the workpiece to be welded, effectively reducing the number of cameras required, thereby simplifying the structure of the wire bonding equipment, reducing the complexity of the control system of the wire bonding equipment, and thus effectively reducing the production cost of the wire bonding equipment.

Therefore, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] This application provides a wire bonding device that can be used to perform wire bonding operations on electronic devices such as circuit boards. The wire bonding device provided in the embodiments of this application will now be described in conjunction with the accompanying drawings.

[0044] Please refer to the following: Figures 1 to 6 The aforementioned wire bonding equipment includes a controller (not shown in the figure), a clamp 100, a vision device 200, and a wire clamping device 300. The clamp 100 is used to hold the workpiece to be bonded. The clamp 100 includes a first mounting base 110 and an inlet base 120. The inlet base 120 is mounted on the first mounting base 110 and includes an inlet member 121. The inlet member 121 has an inlet groove 1211, which includes an inlet section 12111 and a straight section 12112. One end of the straight section 12112 is connected to the inlet section 12111, and the other end of the straight section 12112 is directly opposite to the bonding pad of the workpiece to be bonded. The vision device 200 includes a camera 210, which is electrically connected to the controller. The wire clamping device 300 is electrically connected to the controller. The wire clamping device 300 includes a clamping head assembly 310 and a first driving mechanism 320. The clamping head assembly 310 is used to clamp the wire harness, and the first driving mechanism 320 is used to drive the clamping head assembly 310 to move from the vision mechanism to the fixture 100 so that the welding end of the wire harness can be captured by the camera 210 and then inserted into the guide groove 1211.

[0045] Specifically, please refer to Figure 4 The inlet segment 12111 is roughly funnel-shaped, and the inner diameter of the inlet segment 12111 gradually increases in the direction away from the straight segment 12112.

[0046] It should be noted that the number of inlet slots 1211 can be one or more, depending on the number of workpieces to be soldered held by the fixture 100, or the number of solder pads of the workpieces to be soldered held by the fixture 100. When there are multiple inlet slots 1211, each inlet slot 1211 is set to correspond one-to-one with each solder pad.

[0047] It should also be noted that the first drive mechanism 320 mentioned above includes various types, such as multi-axis manipulators, XYZ axis drive mechanisms, etc., and no specific limitation is made here.

[0048] Compared with the prior art, the wire bonding equipment provided in this application provides an inlet seat 120 on the fixture 100, and an inlet groove 1211 is provided in the inlet part 121 of the inlet seat 120. The inlet groove 1211 includes an inlet section 12111 and a straight section 12112. One end of the straight section 12112 is connected to the inlet section 12111, and the other end of the straight section 12112 is positioned opposite to the pad of the workpiece to be bonded. During wire bonding, the controller controls the clamp assembly 310 to clamp the wire harness. Then, the controller controls the first drive mechanism 320 to move the clamp assembly 310 to the vision device 200, aligning the bonding end of the wire harness with the working end of the camera 210. Next, the controller controls the camera 210 to capture a one-dimensional image of the bonding end of the wire harness. The controller analyzes and calculates this one-dimensional image to obtain the straight-line length of the bonding end of the wire harness, and then calculates the insertion depth for inserting the bonding end of the wire harness into the guide groove 1211. Finally, the controller controls the first drive mechanism 320 to move the clamp assembly 310 to the fixture 100 and insert the bonding end of the wire harness into the guide groove 1211. The guide section 12111 guides the welding end of the wire harness into the straight section 12112 of the guide groove 1211. Under the abutment of the inner wall of the straight section 12112, the welding end of the wire harness is gradually straightened, so that the welding end of the wire harness is roughly straight after passing through the guide groove 1211. At this time, the actual insertion depth of the welding end of the wire harness into the guide groove 1211 is consistent with the insertion depth obtained by the controller after analyzing and calculating the above one-dimensional image. This allows the controller to control the first drive mechanism 320 to insert the welding end of the wire harness into the guide groove 1211 according to the calculated insertion depth, thereby realizing the alignment of the welding end of the wire harness with the solder pad of the workpiece to be welded. Therefore, with the cooperation of the inlet component 121, the above-mentioned wire bonding equipment only needs to use one camera 210 to realize the alignment operation between the welding end of the wire harness and the welding pad of the workpiece to be welded, which effectively reduces the number of cameras 210, thereby effectively simplifying the structure of the wire bonding equipment, reducing the complexity of the control system of the wire bonding equipment, and thus effectively reducing the production cost of the wire bonding equipment.

[0049] In one embodiment of this application, please refer to the following: Figure 2 and Figure 3The fixture 100 also includes a clamping seat 130 and a second driving mechanism 140. The clamping seat 130 includes a base 131, a first clamping member 132 and a second clamping member 133. The base 131 is mounted on a first mounting base 110 and is used to support the workpiece to be welded. The first clamping member 132 is fixedly disposed relative to the base 131, for example, the first clamping member 132 is fixedly connected to the base 131. The second clamping member 133 is disposed relatively separately from the first clamping member 132. The first clamping member 132 is located between the second clamping member 133 and the guide member 121. The second driving mechanism 140 is used to drive the second clamping member 133 to move away from or towards the first clamping member 132, so that the first clamping member 132 and the second clamping member 133 cooperate to clamp or release the workpiece to be welded.

[0050] After the workpiece to be bonded is placed on the base 131, the second drive mechanism 140 drives the second clamping member 133 to move closer to the first clamping member 132 until one side of the workpiece to be bonded abuts against the first clamping member 132 and the other side of the workpiece abuts against the second clamping member 133, thereby clamping and fixing the workpiece to be bonded to limit its horizontal position. After the bonding operation is completed, the second drive mechanism 140 drives the second clamping member 133 to move away from the first clamping member 132, thereby releasing the workpiece to be bonded.

[0051] It should be noted that the second drive mechanism 140 mentioned above includes various types, such as electric pneumatic cylinders, ball screw drive mechanisms, gear and rack drive mechanisms, etc., and no specific limitation is made here.

[0052] Please refer to the above embodiments as well. Figure 2 and Figure 3 The first mounting base 110 is provided with a slide rail 111 parallel to the driving direction of the second driving mechanism 140. The base body 131 is slidably mounted on the slide rail 111. A limiting groove 1311 extending along the driving direction of the second driving mechanism 140 is provided on the side of the base body 131 away from the first clamping member 132. The second clamping member 133 is disposed in the limiting groove 1311. The second driving mechanism 140 drives the base body 131 to move away from or closer to the guide member 121 through the second clamping member 133, so that the base body 131 and the guide member 121 cooperate to clamp or release the workpiece to be welded.

[0053] Specifically, please refer to Figure 3 The first clamping member 132 is provided with a flange 1321, the height of which is equal to the thickness of the workpiece to be welded.

[0054] When the second drive mechanism 140 drives the second clamping member 133 to move closer to the first clamping member 132, the second clamping member 133 abuts against the end of the limiting groove 1311 near the first clamping member 132, thereby driving the seat 131 to move closer to the guide member 121. When the seat 131 reaches below the guide member 121, the flange 1321 abuts against the bottom of the guide member 121. At this time, the seat 131 and the guide member 121 cooperate to clamp the workpiece to be welded. This can limit the vertical position of the workpiece to be welded during the wire welding operation, thereby avoiding the workpiece to be welded from moving up and down during the wire welding operation, and ensuring the welding effect of the wire welding equipment.

[0055] Please refer to the above embodiments as well. Figure 2 and Figure 3 The clamping seat 130 also includes an elastic member 134, which abuts against the seat body 131 and the second clamping member 133. The seat body 131 is provided with a limiting part 1312, which is used to abut against the guide seat 120.

[0056] When the second drive mechanism 140 drives the second clamping member 133 to move toward the first clamping member 132, the second clamping member 133 drives the seat 131 to move toward the guide member 121 through the elastic member 134 until the limiting part 1312 abuts against the guide seat 120. At this time, the seat 131 stops moving, while the second clamping member 133 continues to move toward the guide member 121. The elastic member 134 is compressed and deformed, and the second clamping member 133 and the first clamping member 132 cooperate to clamp the workpiece to be welded. When the second drive mechanism 140 drives the second clamping member 133 to move away from the first clamping member 132, the elastic member 134 gradually returns to its original position. When the second clamping member 133 abuts against the end of the limiting groove 1311 away from the first clamping member 132, the second clamping member 133 drives the seat body 131 to move away from the guide member 121 until the second clamping member 133 moves to its initial position. At this time, under the elastic action of the elastic member 134, the seat body 131 and the second clamping member 133 are relatively stationary, and the clamp 100 is in the open state. By setting the elastic member 134 between the second clamping member 133 and the seat body 131, the seat body 131 can be prevented from continuing to move under its own inertia when the second clamping member 133 returns to its initial position, thereby achieving precise positioning of the seat body 131 and ensuring that the pick-and-place device can be accurately aligned with the seat body 131 to pick up and place the workpiece to be welded, effectively improving the working reliability of the wire welding equipment.

[0057] Please refer to the above embodiments as well. Figure 2 and Figure 3The clamping base 130 also includes a guide post 135 parallel to the driving direction of the second driving mechanism 140; the guide post 135 is disposed on the base body 131, and the second clamping member 133 has a guide hole; or, the guide post 135 is disposed on the second clamping member 133, and the base body 131 has a guide hole; the guide post 135 passes through the guide hole, and the elastic member 134 is a spring, which is sleeved on the guide post 135.

[0058] By using a spring as the elastic element 134 and sleeved on the guide post 135, the elastic element 134 can be prevented from dislodging from the position between the second clamping member 133 and the seat 131, thereby further improving the working reliability of the wire bonding equipment.

[0059] In the above embodiments, the clamp 100 further includes a threaded component (not shown in the figure); the limiting part 1312 has a threaded hole extending along the driving direction of the second driving mechanism 140, one end of the threaded component is threaded into the threaded hole, and the other end of the threaded component is used to abut against the guide seat 120; or, the guide seat 120 has a threaded hole extending along the driving direction of the second driving mechanism 140, one end of the threaded component is threaded into the threaded hole, and the other end of the threaded component is used to abut against the limiting part 1312.

[0060] By opening a threaded hole extending in the driving direction of the second drive mechanism 140 on the limiting part 1312 or the guide seat 120, and threading one end of the threaded part into the threaded hole, the threaded part can be screwed to change the extension length of the threaded part according to the actual application needs, thereby adjusting the relative position of the seat 131 and the guide part 121. This makes the above-mentioned fixture 100 applicable to different types of workpieces to be welded, effectively improving the versatility of the wire welding equipment.

[0061] In the above embodiments, please refer to Figure 4 The inlet groove 1211 has a wire take-out port, which extends from one end of the inlet groove 1211 to the other end of the inlet groove 1211. The seat 131 can close the wire take-out port when it moves to the inlet member 121.

[0062] Specifically, please refer to the following: Figures 2 to 4The inlet slot 1211 is located at the bottom of the inlet piece 121, and the wire take-out port is positioned directly opposite the first mounting base 110. The inlet seat 120 also includes a support 122. The inlet component 121 is mounted on the first mounting seat 110 via the support 122. The support 122 has an insertion space. When the seat body 131 moves to the inlet seat 120, part of the seat body 131 enters the insertion space and is located below the inlet component 121. The part of the seat body 131 that enters the insertion space closes the wire take-up port. At this time, the wire clamping device 300 inserts the welding end of the wire harness into the inlet groove 1211. After the wire welding operation is completed, the seat body 131 moves away from the inlet component 121. Then the seat body 131 leaves the insertion space, the wire take-up port opens, and the wire harness can be removed from the inlet groove 1211 through the wire take-up port without having to pull the wire harness out along the axial direction of the inlet groove 1211. This effectively avoids damage to the welding part between the wire harness and the workpiece to be welded due to external force pulling.

[0063] Please refer to the above embodiments as well. Figure 2 and Figure 3 The clamping base 130 also includes a first limiting member 136 and a second limiting member 137. The first limiting member 136 and the second limiting member 137 are respectively separated on the base body 131, and the first limiting member 136 and the second limiting member 137 are both located between the first clamping member 132 and the second clamping member 133. Thus, when the clamp 100 is in the closed state, the first clamping member 132, the second clamping member 133, the first limiting member 136 and the second limiting member 137 cooperate to limit the workpiece to be welded, thereby effectively limiting the horizontal position of the workpiece to be welded, so as to avoid the workpiece to be welded from shifting during the welding operation, and ensuring the welding effect of the welding equipment.

[0064] In one embodiment of this application, please refer to Figure 5 The chuck assembly 310 includes a second mounting base 311, a first chuck 312, and a second chuck 313. The second mounting base 311 is connected to the power output end of the first drive mechanism 320. The first chuck 312 and the second chuck 313 are both mounted on the second mounting base 311, and the first chuck 312 and the second chuck 313 are arranged in sequence.

[0065] During operation, the first drive mechanism 320 drives the chuck assembly 310 to move toward the fixture 100, and then inserts the welding end of the wire harness into the guide groove 1211 of the guide member 121. Then the first chuck 312 opens, and the first drive mechanism 320 continues to drive the chuck assembly 310 to move toward the fixture 100, so that the welding end of the wire harness is inserted into the straight section 12112 under the guiding action of the guide section 12111 until it reaches the solder pad of the workpiece to be welded.

[0066] Traditional wire-clamping devices typically have only one clamp. When the clamp holds the wire harness, the exposed length of the welded end is relatively large, and the degree of curvature of this exposed portion is also significant, leading to a large error in calculating the straight length of the welded end. This application, by employing both a first clamp 312 and a second clamp 313 to jointly clamp the wire harness, effectively reduces the exposed length of the welded end, thereby significantly reducing the calculation error in the straight length of the welded end, ensuring the detection accuracy of the vision device 200, and effectively improving the operational reliability of the wire-bonding equipment.

[0067] In one embodiment of this application, please refer to Figure 5 The wire clamping device 300 also includes a third mounting base 330, on which the first drive mechanism 320 is mounted.

[0068] In one embodiment of this application, please refer to Figure 6 The vision device 200 also includes a supplementary light 220, which is positioned directly opposite the working end of the camera 210. The supplementary light 220 is a surface light source. When photographing the soldering end of the wire harness, the surface light source illuminates the soldering end of the wire harness, effectively preventing the color of the wire harness from adversely affecting the shooting effect of the camera 210, thereby effectively improving the working reliability of the wire bonding equipment.

[0069] In other embodiments, the supplementary light 220 may also be a point light source.
