Description

Technical Field

[0001] The utility model relates to the technical field of bonding processing, in particular to an anti-stuck material bonding machine. Background Art

[0002] A bonding machine is a device that uses the combined effects of ultrasound, pressure, and time to cause atomic diffusion of two metals in contact with each other to form metal compounds or alloys, thereby reliably bonding the metal wire to the chip and the carrier. A bonding machine is mainly used to connect the chip to the carrier with a metal wire. Bonding is a welding process that connects the metallized circuit leads or electrodes on the circuit chip to the metal leads of the assembled chip or the lead-out electrode wires of the casing one by one.

[0003] When adjusting the positions of the splitter, cutter and clamping jaws of the bonding head, it is not easy for the operator to observe with naked eyes, making debugging difficult.

[0004] The existing patent (publication number: CN218396584U) discloses a device, including an image acquisition mechanism, a camera assembly, and an optical path channel. By setting up the image acquisition mechanism to acquire images of the working end of the bonding head mechanism, the positional relationship between the various components of the working end of the bonding head mechanism can be clearly observed, which is convenient for operators to observe and debug.

[0005] However, the above patent still has certain defects. When welding the workpiece, it is relatively delicate and it is necessary to ensure that the position of the workpiece cannot be moved. A slight movement deviation may cause the welding failure of the product. Since the packaging carrier is a relatively thin workpiece, excessive force when the clamp is clamped and limited may cause damage to it, and the limiting effect will be poor if the clamping force is too small. At the same time, when the workpiece is fed, the packaging carrier is thin and light, so it is easy to get stuck. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] An anti-stuck material bonding machine, such as Figures 1 to 3As shown, the operating table 100 includes a feeding mechanism 200 rotatably connected to the inner wall of the operating table 100, a keying assembly 300 is fixedly connected to the top of the operating table 100, a fixing mechanism 400 is fixedly connected to one side of the keying assembly 300, and a limiting mechanism 500 is provided on the operating table 100; the limiting mechanism 500 is provided with two groups, and a collecting box 600 is provided on one side of the operating table 100; the fixing mechanism 400 includes a lifting plate 410 fixedly connected to one side of the keying assembly 300, and the lifting plate 410 is fixedly connected to the one side of the keying assembly 300. The inner wall of the plate 410 is fixedly connected to the limit rod 420, and the outer wall of the limit rod 420 is slidably connected to the fixed component 430. The lifting plate 410 and the fixed component 430 are each provided with two groups; the fixed component 430 includes a connecting block 431 slidably connected to the outer wall of the limit rod 420, and the bottom end of the connecting block 431 is fixedly connected to a spring 432, and the spring 432 is provided with multiple groups. The bottom end of the spring 432 is fixedly connected to a pressure plate 433, and the inner wall of the connecting block 431 is threadedly sleeved with a threaded rod 440.

[0028] Before processing, the distance between the two groups of fixed components 430 is adjusted according to the size of the workpiece. Since the inner wall of the connecting block 431 is connected to the threaded rod 440, a thread matching the outer wall thread of the threaded rod 440 is provided. Rotating the threaded rod 440 drives the connecting block 431 to move. Under the restriction of the movement trajectory of the connecting block 431 by the limiting rod 420, the threaded rod 440 is rotated to drive the connecting block 431 to move along the limiting rod 420, thereby adjusting the position of the two groups of pressing plates 433. The outer wall of the threaded rod 440 is provided with two groups of symmetrical threads. The rotation of the threaded rod 440 drives the two groups of fixed components 430 to move in opposite directions. After adjusting the position of the two groups of fixed components 430, the feeding mechanism 200 is started to connect. The driving member drives the workpiece to move to the bottom of the fixing mechanism 400, and then the bonding head in the bonding assembly 300 moves downward to approach the workpiece and processes it. When the bonding head moves downward, it drives the lifting plate 410 to move downward, thereby driving the connecting block 431 to move downward, and then drives the pressing plate 433 to fit with the surface of the workpiece, fixes the workpiece and prevents the workpiece from moving during processing and affecting the processing effect. After the bottom surface of the pressing plate 433 contacts the top surface of the workpiece, the connecting block 431 continues to descend and drives the spring 432 to be compressed, and will not continue to drive the pressing plate 433 to continue to press the workpiece, thereby generating greater pressure on the workpiece and damaging it. At the same time, workpieces of different heights can be fixed.

[0029] Please refer to Figure 2The feeding mechanism 200 includes a feeding assembly 210 rotatably connected to the inner wall of the operating table 100, a connecting rod 220 is fixedly connected to the top of the feeding assembly 210, a pushing block 230 is fixedly connected to the top of the connecting rod 220, two groups of feeding assemblies 210 are provided, and multiple groups of pushing blocks 230 are provided; a rotating shaft 240 is fixedly connected to the inner wall of the operating table 100, a feeding roller 250 is rotatably connected to the outer wall of the rotating shaft 240, and the feeding roller 250 is rotatably connected to the operating table 100, and multiple groups of the rotating shaft 240 and the feeding roller 250 are provided; the feeding assembly 210 includes a connecting rod 220 fixedly connected to the top of the connecting rod 220, and a pushing block 230 is fixedly connected to the top of the connecting rod 220. The inner wall of the workbench 100 is rotatably connected to a positioning shaft 211, and the outer wall of the positioning shaft 211 is rotatably connected to a first rotating plate 212, and one side of the first rotating plate 212 is fixedly connected to a first connecting shaft 213, and the outer wall of the first connecting shaft 213 is rotatably connected to a connecting plate 214, and one side of the connecting plate 214 is fixedly connected to a second connecting shaft 215, and the outer wall of the second connecting shaft 215 is rotatably connected to a second rotating plate 216, and the top of the second rotating plate 216 is fixedly connected to a connecting rod 220, and the positioning shaft 211, the first rotating plate 212 and the first connecting shaft 213 are each provided in two groups.

[0030] The workpiece is placed on the feeding roller 250, and one end of the positioning shaft 211 is connected to a driving member through a coupling. The driving member is started to drive the positioning shaft 211 to rotate, thereby driving the first rotating plate 212 to rotate around the positioning shaft 211 as the axis, and then driving the first connecting shaft 213 to rotate around the positioning shaft 211 as the axis. The change in the position of the first connecting shaft 213 drives the connecting plate 214 to move, thereby driving another group of first connecting shafts 213 connected to the first connecting shaft 213 to move, and driving the first rotating plate 212 connected to this group of first connecting shafts 213 to move around this group of positioning shafts 211 as the axis. The movement of the connecting plate 214 drives the second connecting shaft 215 to move, thereby driving the second rotating plate 216 to move, and driving the connecting rod 220 to move, and then driving the pushing block 230 to move. At this time, the movement trajectory of the pushing block 230 is to first move upward to approach the workpiece, then push the workpiece to move forward, and then the pushing block 230 moves downward away from the workpiece, and then moves backward to reset, and continues to push the next group of workpieces in the same way. The pushing block 230 pushes the workpiece to move and drives the feeding roller 250 to rotate with the rotating shaft 240 as the axis, so that the movement of the workpiece on the operating table 100 is smoother and less likely to get stuck.

[0031] Please refer to Figure 2 The limiting mechanism 500 includes a limiting groove 510 opened on the operating table 100, a rack 520 is slidably connected in the limiting groove 510, a gear 530 is meshed with the rack 520, a rotating shaft 540 is fixedly connected to the inner wall of the gear 530, the gear 530 is rotatably connected to the operating table 100, a scale 550 is fixedly connected to the top of the operating table 100, and one end of the rack 520 is fixedly connected to the limiting plate 560.

[0032] Before processing, the distance between the two sets of limit plates 560 through which the workpiece can pass is adjusted according to the size of the workpiece. Specifically, the rotating shaft 540 drives the scale 550 to rotate, thereby driving the rack 520 to move in the limit groove 510. The moving distance of the rack 520 can be intuitively seen according to the scale 550, so as to adjust the positions of the two sets of limit plates 560 and change the distance between the two sets of limit plates 560. A certain gap is left between the two sets of limit plates 560 and the workpiece, and they are not tightly fitted against the workpiece, so as to prevent the feeding mechanism 200 from getting stuck when driving the workpiece to move. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
