Description

Technical Field

[0001] This invention relates to the field of semiconductor manufacturing technology, and in particular to an automatic plugging device for a feed tube. Background Technology

[0002] After the wafer packaging of semiconductor products is completed, a sorting machine is used to test the chips to determine whether the packaged finished product is qualified and whether its function meets the standards. Generally, packaged chips are placed in tubing and transported through the tubing. To prevent chips from falling out during transportation and causing appearance defects, a rubber stopper is often installed at one end of the tubing. During testing, the rubber stopper needs to be removed, and the chips in the tubing need to be poured out for testing.

[0003] Initially, rubber stoppers were removed manually, but the removal speed couldn't keep up with the testing speed, causing the separator to malfunction, resulting in equipment interruptions, and easily leading to problems such as material mixing, spillage, and insufficient material. To speed up the removal process, an automatic stopper removal device was adopted. In existing technology, the stopper removal device is generally located below the feed hopper of the separator, including two clamps positioned opposite each other on both sides of the hopper. The feed tube automatically falls through the separator to the stopper removal position, where one clamp holds the tail of the feed tube to position it, and the other clamps the rubber stopper and removes it. Although the plug removal speed has been improved, some problems still exist: 1. The feed tube automatically falls to the plug removal position through the separator, but the plug removal position is inaccurate or not in place, resulting in the plug not being removed; 2. The feed tube is only fixed by clamping the tail end of the feed tube, and the front end of the feed tube is prone to displacement. Moreover, the clamping direction is in a straight line with the plug removal direction, making the feed tube easy to slide and unstable, thus causing the plug not to be removed; 3. After the clamps that hold the rubber plugs are released, some rubber plugs will stick to the clamps and will not fall off automatically, requiring manual assistance to clean the plugs, causing equipment operation interruption. Summary of the Invention

[0004] The present invention aims to provide an automatic plug-removing device for a feed tube to overcome the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automatic plug removal device for a material tube, comprising a conveying mechanism, a positioning mechanism, a plug removal mechanism, and a plug clearing mechanism. The conveying mechanism is used to separate and convey the material tube. The positioning mechanism includes two positioning components symmetrically arranged on both sides of the conveying mechanism. The two positioning components position and fix the two ends of the material tube. The plug removal mechanism is located on one side of the positioning mechanism and is used to remove the rubber plug on the material tube. The plug clearing mechanism is located on the plug removal mechanism and is used to blow and push the rubber plug so that it falls into a collection box located below the plug removal mechanism.

[0006] Furthermore, in the aforementioned automatic plug-removing device for the material tube, the positioning component includes a mounting plate, a mounting base, a clamping plate one, and a clamping plate two. The mounting plate is fixed on the conveying mechanism, the mounting base is fixed below the mounting plate, and the clamping plate two is rotatably connected to the mounting base via a connecting rod assembly. The clamping plate one is inserted into the mounting plate, with its upper end protruding from the mounting plate, and the clamping plate one and clamping plate two cooperate to clamp the material tube. Moreover, the clamping parts of the clamping plate one, clamping plate two, and the material tube are all made of elastic plastic.

[0007] Furthermore, in the aforementioned automatic plug-removing device for the feed tube, the connecting rod assembly includes a second cylinder, a first connecting rod, and a second connecting rod. The second cylinder is fixed to the rear side of the mounting base. One end of the first connecting rod is hinged to the telescopic end of the second cylinder. The second connecting rod is a Y-shaped rod, with its first end hinged to the end of the first connecting rod away from the second cylinder, its second end hinged to the mounting base, and its third end inserted into the mounting plate and aligned with the second end. The second clamping plate is located on top of the third end.

[0008] Furthermore, in the aforementioned automatic plug-removing device for the feed tube, the positioning component further includes a cylinder, which is fixed to the front side of the mounting base. The telescopic end of the cylinder is connected to a clamping plate, and when the cylinder retracts, the clamping plate retracts into the mounting plate.

[0009] Furthermore, in the aforementioned automatic plug-removing device for the feed tube, the plug-removing mechanism includes a transverse moving assembly, a transverse moving seat, a guide block, a gripper assembly, and a detection assembly. The transverse moving assembly is mounted on the conveying mechanism and is used to drive the transverse moving seat closer to or further away from the plug end of the feed tube. Preferably, the transverse moving assembly includes a fixed seat, a lead screw, a nut seat, a connecting plate, and a servo motor. The fixed seat is mounted on the conveying mechanism, and both ends of the lead screw are supported on the fixed seat by bearings. The nut seat is connected to a sliding nut on the lead screw and is also slidably connected to a slide rail on the fixed seat. One end of the lead screw extending out of the fixed seat is connected to the servo motor through a transmission structure. The transverse moving seat is connected to the nut seat through the connecting plate. The guide block is fixed above the transverse moving seat on the side near the feed tube and has a guide hole through which the feed tube passes. The gripper assembly is located behind the guide hole and is used to grip the plug. The detection assembly is used to detect whether the feed tube is in place. Two sets of detection assemblies are provided, symmetrically arranged on both sides of the guide hole.

[0010] Furthermore, in the aforementioned automatic plug removal device for the material tube, the clamping assembly includes a clamping cylinder, which is fixed above the transverse seat. The clamping cylinder is equipped with two opposing clamps, namely an upper clamp and a lower clamp, which cooperate to clamp the rubber plug.

The slider is mounted on a transverse base, and the step pin is fixed to the slider. The sensing block is sleeved around the step pin and rotatably connected to it. The sensing block is L-shaped, with one end being a sensing block and the other end being a striking block. The striking block is located behind the guide block and extends to the guide hole. When the feed tube plug passes through the guide hole, it collides with the striking block, causing the sensing block to rotate. The guide block has a first spring hole for the sensing block to pass through. The first spring is located in the first spring hole and connects the guide block and the sensing block. The second detection sensor is located outside the guide block, above and below the first spring hole. The sensing block is inserted into the first spring hole and extends from the first spring hole to the outside of the guide block to cooperate with the second detection sensor.

[0012] Furthermore, in the aforementioned automatic plug-removing device for the feed tube, the plug-removing mechanism further includes a push-away component. The push-away component is used to push away the impact block that collides with the feed tube. It includes a push plate, a push-away cylinder, and a second spring. The slider is provided with a sliding part and a wedge-shaped part. The sliding part and the wedge-shaped part are located on opposite sides of the slider in the same direction. The push plate is provided with an inclined surface that cooperates with the wedge-shaped part. The second push-away cylinder is fixed below the transverse moving seat, and its telescopic end is connected to the push plate. The transverse moving seat is provided with a through sliding hole. The sliding part is inserted into the sliding hole and slidably connected to the sliding hole. The second spring is located in the sliding hole, with one end connected to the sliding part and the other end connected to an end plate fixed on the outside of the transverse moving seat that closes the sliding hole.

[0013] Furthermore, in the aforementioned automatic plug removal device for the material tube, the plug removal mechanism includes a cylinder three and a plug removal seat. The cylinder three is fixed on the transverse moving seat, and the telescopic end of the cylinder three is connected to the plug removal seat. The plug removal seat is provided with an air blowing part located between the upper and lower jaws. The end of the air blowing part is provided with an air blowing port one facing the rubber plug. The top of the plug removal seat is provided with an interface communicating with the air blowing port one. The interface is connected to an air pipe and communicates with an external source.

[0014] Furthermore, in the aforementioned automatic plug removal device for the material tube, the plug removal seat is also provided with an ejector part, which is located directly below the air blowing part. The lower jaw is provided with an ejector hole, and the ejector part is inserted into the ejector hole and slidably connected to the ejector hole. The ejector part can extend out of the ejector hole when the plug removal cylinder extends. The end of the ejector part is provided with an air blowing port two that communicates with the interface.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figure 1-10As shown, an automatic plug-removing device for a material tube includes a conveying mechanism 1, a positioning mechanism 2, a plug-removing mechanism 3, and a plug-clearing mechanism 4. The conveying mechanism 1 is used to separate and convey the material tube 5. This invention uses a belt conveying mechanism 1. During plug removal, the conveying mechanism 1 stops, and the material tube 5 is located on the conveyor belt of the conveying mechanism 1. After plug removal, the material tube 5 is conveyed to a sorting machine through the conveying mechanism 1. The positioning mechanism 2 includes two positioning components symmetrically arranged on both sides of the conveying mechanism 1. The two positioning components position and fix the two ends of the material tube 5. The plug-removing mechanism 3 is located on one side of the positioning mechanism 2 and is used to remove the rubber plug on the material tube 5. The plug-clearing mechanism 4 is located on the plug-removing mechanism 3 and is used to blow and push the rubber plug so that it falls into a collection box (not shown in the figure) located below the plug-removing mechanism 3. Figure 6 As shown, the plug removal mechanism and the plug clearing mechanism are covered with protective shells. During operation, the conveying mechanism 1 automatically separates and conveys the material tube 5 into the positioning mechanism 2. The two ends of the material tube are fixed by two positioning components, making it difficult for the material tube to shift or slide. The positioning is accurate and firm, avoiding the inability to remove the plug due to inaccurate positioning or displacement. Then, the plug removal mechanism 3 starts to remove the plug near the end of the material tube 5. The plug removal direction is perpendicular to the conveying direction of the conveying mechanism 1, making the plug removal more stable. After the plug is removed, the cleaning mechanism 4 blows and pushes the plug to prevent the plug from sticking to the gripper or falling onto the equipment. This can achieve fully automatic plug removal with a 100% success rate, solving the problems of plugs that cannot be removed and plugs that stick and require manual assistance to clear.

[0035] Among them, such as Figure 5 , 7 As shown, the plug removal mechanism 3 includes a transverse component 31, a transverse seat 32, a guide block 33, a gripper assembly 34, and a detection assembly 35. The transverse component 31 is mounted on the conveying mechanism 1 and is used to drive the transverse seat 32 to approach or move away from the plug end of the material tube 5. The transverse component 31 includes a fixed seat 311, a lead screw 312, a nut seat 313, a connecting plate 314, and a servo motor 315. The fixed seat 311 is mounted on the conveying mechanism 1. The two ends of the lead screw 312 are supported and mounted on the fixed seat 311 by bearings. The nut seat 313 is connected to a sliding nut on the lead screw 312. The nut seat 313 is also slidably connected to a slide rail 316 provided on the fixed seat 311. One end of the lead screw 312 extending out of the fixed seat 311 is connected to the servo motor 315 through a transmission structure. In this embodiment, the transmission structure is a synchronous belt transmission structure. The transverse seat 32 is connected to the nut seat 313 through the connecting plate 314.

[0036] like Figure 5-8As shown, the guide block 33 is fixed above the transverse seat 32 on the side near the material tube 5. It has a guide hole 331 through which the material tube 5 passes. The guide hole 331 is tapered on the side near the material tube 5 to facilitate the entry of the material tube. The gripper assembly 34 is located behind the guide hole 331 and is used to grip the rubber stopper. The detection assembly 35 is used to detect whether the material tube 5 is in position. Two sets of detection assemblies are symmetrically arranged on both sides of the guide hole 331. When the material tube 5 is positioned, the transverse assembly 31 moves the transverse seat 32 closer to the material tube 5. The rubber stopper will first insert into the rear side of the guide hole 331, triggering the detection assembly 35 to detect whether the material tube 5 is in position. After the material tube is in position, the gripping assembly 34 starts to grip the rubber stopper, and then the transverse seat 32 retracts to remove the rubber stopper. The plug removal mechanism 3 has a simple and compact structure and is easy to operate. Because the rubber stopper may be misaligned during installation, one set of detection assemblies may not detect it or may detect it incorrectly. The setting of two sets of detection assemblies 35 can avoid this phenomenon.

[0037] In the above structure, such as Figure 5-8 As shown, the clamping assembly 34 includes a clamping cylinder 341, which is fixed above the transverse support 32. Two opposing clamping jaws, an upper clamping jaw 342 and a lower clamping jaw 343, are mounted on the clamping cylinder 341. The upper clamping jaw 342 and the lower clamping jaw 343 cooperate to clamp the rubber stopper. The clamping ends of the upper clamping jaw 342 and the lower clamping jaw 343 are both set with beveled sharp angles, which can more easily clamp the rubber stopper. The upper clamping jaw 342 and the lower clamping jaw 343 are provided with a photoelectric detection sensor 344, which is used to detect whether the rubber stopper is in place. When the rubber stopper enters the front side of the upper jaw 342 and the lower jaw 343, the detection sensor 344 is triggered, and then the jaw cylinder 341 is activated to control the upper and lower jaws to pick up the rubber stopper. Then the lateral movement component moves backward to remove the rubber stopper. The clamping operation is simple, and the setting of the detection sensor 344 can better control the cycle and improve the efficiency of removing the rubber stopper.

[0038] In addition, such as Figure 5-8As shown, the detection component 35 includes a sensing block 351, a step pin 352, a slider 353, a second detection sensor 354, and a first spring 355. The slider 353 is mounted on the transverse support 32, and the step pin 352 is fixed to the slider 353. The sensing block 351 is sleeved around the step pin 352 and rotatably connected to it. The sensing block 351 is L-shaped, with one end being a sensing block 3511 and the other end being a striking block 3512. The striking block 3512 is located on the rear side of the guide block 33 and extends to the guide hole 331. When the plug passes through the guide hole 331, it collides with the impact block 3512, pushing the sensing impact block 351 to rotate; the guide block 33 is provided with a spring hole 332 for the sensing block 3511 to pass through, the spring 355 is provided in the spring hole 332 and connects the guide block 33 and the sensing block 3511, the detection sensor 354 is provided on the outside of the guide block 33, located on the upper and lower sides of the spring hole 332, the sensing block 3511 is inserted in the spring hole 332 and extends from the spring hole 332 to the outside of the guide block 33 to cooperate with the detection sensor 354. When the material tube 5 is inserted into the guide hole 331 and the rubber plug passes through the back side of the guide hole 331, it collides with the impact block 3512, overcoming the elastic force of the spring 355 and pushing the sensing impact block 351 to rotate. At this time, the sensing block 3511 rotates in the direction of the detection sensor 354 to trigger the detection sensor 354, thereby realizing the detection of whether the material tube 5 is in place; and the setting of the spring 355 makes the sensing impact block 351 and the guide block 33 elastically connected, ensuring the accurate cooperation between the sensing block 3511 and the detection sensor 354.

[0039] In addition, such as Figure 8 , 10As shown, the plug-removing mechanism 3 further includes a push-away component 36, which is used to push the impact block 3512 that collides with the material tube 5 away from the material tube 5. The push-away component 36 includes a push plate 361, a push-away cylinder 362, and a spring 363. The slider 353 is provided with a sliding part 3531 and a wedge-shaped part 3532. The sliding part 3531 and the wedge-shaped part 3532 are located on opposite sides of the slider 353 in the same direction. The push plate 351 is provided with a component corresponding to the wedge-shaped part 3532. The inclined surface of the 2-partition assembly is used. The push-off cylinder 362 is fixed below the transverse base 32, and its telescopic end is connected to the push plate 361. The transverse base 32 has a through sliding hole 321. The sliding part 3531 is inserted into the sliding hole 321 and slidably connected to the sliding hole 321. The second spring 363 is located in the sliding hole 321, with one end connected to the sliding part 3531 and the other end connected to the end plate 364 fixed on the outside of the transverse base 32 to close the sliding hole 321. When the rubber plug collides with the impact block 3512, in order to ensure that the material tube 5 can enter the clamping position more smoothly and reduce the damage to the surface of the material tube 5, the push-off assembly 36 is activated. The push-off cylinder 362 is activated, which drives the push plate 361 to move towards the end of the material tube 5. Due to the wedge-shaped fit, the push plate 361 pushes the two sliders 353 to move outward, thereby pushing the impact block 3512 to rotate outward and separate from the material tube 5. After the transverse seat 32 moves backward and the material tube 5 exits the guide hole 331, it is pushed away from the cylinder 362 to reset. Under the action of the second spring 363, the slider 353 moves inward and is tightly connected to the inclined surface of the push plate 361.

[0040] Among them, such as Figure 5-9 As shown, the plug-removing mechanism 4 includes a cylinder 3 41 and a plug-removing seat 42. The cylinder 3 41 is fixed on the transverse support 32, and its telescopic end is connected to the plug-removing seat 41. The plug-removing seat 41 is provided with an air blowing part 421 located between the upper jaw 342 and the lower jaw 343. The end of the air blowing part 421 is provided with an air blowing port 422 facing the plug. The top of the plug-removing seat 42 is provided with an interface 423 communicating with the air blowing port 422. The interface 423 is connected to an air pipe and communicates with an external source. After the plug is pulled out and retracted a certain distance, the upper and lower jaws release the plug, the cylinder 3 41 extends, and moves the plug-removing seat 42 closer to the gripping position of the jaws. Then, air is blown, and the air blowing port 42 blows the plug away from the jaws or the equipment, causing it to fall automatically into the collection box below. This avoids manual plug removal, ensures continuous operation of the equipment, and improves production efficiency.

[0041] In addition, such as Figure 8 , 9As shown, the plug-clearing seat 42 is also provided with an ejector part 424, which is located directly below the air blowing part 422. The lower gripper 343 is provided with an ejector hole 3431, and the ejector part 424 is inserted into the ejector hole 3431 and slidably connected to the ejector hole 3431. The ejector hole 3431 is an elongated hole. When the lower gripper 343 opens and closes, the ejector part 424 slides vertically. When the cylinder 3 41 extends, the ejector part 424 can extend out of the ejector hole 3431. The end of the ejector part 424 is provided with an air blowing port 425 communicating with the interface 423. By setting the ejector part 424, the air blowing range can be increased, further ensuring the plug-clearing effect, and preventing the rubber plug from falling to the position of the detection sensor 344, which would affect the detection effect.

[0042] Example 2

[0043] Based on the structure of Example 1, such as Figure 1-3 As shown, the positioning assembly includes a mounting plate 21, a mounting base 22, a first clamping plate 23, and a second clamping plate 24. The mounting plate 21 is fixed to the conveying mechanism 1, and the mounting base 22 is fixed below the mounting plate 21. The second clamping plate 24 is rotatably connected to the mounting base 22 via a connecting rod assembly. The first clamping plate 23 is inserted into the mounting plate 21, with its upper end protruding from the mounting plate 21. The first clamping plate 23 and the second clamping plate 24 cooperate to clamp the material tube 5. The clamping parts of the first clamping plate 23, the second clamping plate 24, and the material tube 5 are all made of elastic plastic, providing good clamping force and preventing damage to the material tube. When the material tube is conveyed to the first clamping plate 23 by the conveying mechanism 1, the two first clamping plates 23 protrude from the mounting plate to stop both ends of the material tube 5, initially positioning the material tube 5. Then, the second clamping plate 24 is driven to rotate via the connecting rod assembly to cooperate with the first clamping plate 23 to clamp both ends of the material tube 5, completely positioning the material tube. The structure is simple, the positioning is accurate and stable, which is beneficial for subsequent plug removal.

[0044] In the above structure, such as Figure 2-4 As shown, the connecting rod assembly includes a second cylinder 25, a first connecting rod 26, and a second connecting rod 27. The second cylinder 25 is fixed to the rear side of the mounting base 22. The first connecting rod 26 is H-shaped, with one end hinged to the telescopic end of the second cylinder 25. The second connecting rod 27 is Y-shaped, with its first end hinged to the end of the first connecting rod 26 away from the second cylinder 25, its second end hinged to the mounting base 22, and its third end inserted into the mounting plate 21, aligned with the second end. The second clamping plate 24 is located on top of the third end. When the second cylinder 25 extends or retracts, it drives the first connecting rod 26 and the second connecting rod 27 to rotate, thereby rotating the second clamping plate 24. When the second cylinder 24 extends, the second clamping plate 24 (the third end) rotates to a vertical position, parallel to the first clamping plate 23, providing a secure clamping grip.

[0045] In addition, such as Figure 1-4As shown, the positioning assembly also includes a cylinder 28, which is fixed to the front side of the mounting base 22. The telescopic end of the cylinder 28 is connected to a clamping plate 23. When the cylinder 28 retracts, the clamping plate 23 retracts into the mounting plate 21. After the plug is removed, the cylinder 28 and clamping plate 23 retract, and the material tube is no longer stopped. The material tube 5 can be automatically conveyed to the next station under the action of the conveying mechanism, eliminating the need for a separate transfer mechanism. This design is simple in structure, easy to operate, and improves equipment utilization.

[0046] The working principle of the automatic plug removal device for the feed tube described in this invention is as follows: The feed tube 5 is separated and conveyed to the positioning mechanism 2 by the conveying mechanism 1. Two clamping plates 23 stop the two ends of the feed tube 5, initially positioning the feed tube 5. Then, clamping plate 24 rotates and cooperates with clamping plate 23 to clamp the two ends of the feed tube 5, completely positioning the feed tube. After the feed tube 5 is positioned, the transverse moving component 31 drives the transverse moving seat 32 to approach the feed tube 5. The rubber plug will first insert into the back of the guide hole 331 and collide with the sensing block 351, triggering the detection sensor 354 to detect whether the feed tube 5 is in place, thereby triggering the control to push it away. When component 36 is activated, it pushes the sensing block 351 away from the material tube. When the detection sensor 344 is triggered, the rubber plug reaches the clamping position, and the clamping cylinder 341 starts to clamp the rubber plug. Then, the transverse seat 32 retracts and pulls out the rubber plug. After retracting a certain distance, the rubber plug separates from the material tube, realizing the removal of the rubber plug. Then, the gripper cylinder 341 releases the rubber plug, and the plug-clearing mechanism 4 is activated. The plug-clearing seat 41 approaches the clamping position of the gripper and connects the air source to blow air, blowing the rubber plug away from the gripper and the equipment, so that it automatically falls into the collection box below, realizing the removal and collection of the rubber plug. In addition, while clearing the plug, the clamping plate 23 retracts into the mounting plate 21, and the material tube 5 is automatically transported to the next station under the action of the conveying mechanism 1 to start the removal of the plug from the next material tube 5. The entire process adopts intelligent unmanned operation and can run continuously, which greatly improves production efficiency.
