Description

Technical Field

[0001] The present invention relates to the technical field of physical strength detection, and particularly to a strength detection device for the production of heat-sealing cover tapes. Background Technique

[0002] A heat-sealing cover tape refers to a strip-shaped product applied in the field of electronic packaging. It is used in conjunction with a carrier tape. The cover tape usually has a polyester or polypropylene film as the base layer and is compounded or coated with different functional layers. It can be sealed on the surface of the carrier tape under external force or heating to form a closed space to protect the electronic components in the carrier tape pockets. Strength detection is to understand the maximum tensile force that the packaging material can withstand after heat-sealing. If the strength is insufficient, it may lead to packaging damage, leakage of the contents, or moisture absorption.

[0003] Considering that when detecting the heat-sealing cover tape, multiple detections are carried out simultaneously. While the heat-sealing cover tape is undergoing a tensile test, a pressure or puncture test will be carried out to detect the strength of the heat-sealing cover tape under extreme conditions. The prior art blows air on the heat-sealing cover tape when detecting it and blows away the impurities on the heat-sealing cover tape to increase the detection accuracy. However, at this time, the heat-sealing cover tape is in a taut state. When blowing air on the heat-sealing cover tape, the heat-sealing cover tape will be impacted by the air, which may cause the heat-sealing cover tape to undergo large deformations under the force and break. Considering that the prior art needs to replace the pressure sensor and the detection cone when performing the pressure test and the puncture test, and manual replacement is required. If the heat-sealing cover tape is touched and broken during the replacement, the heat-sealing cover tape may be thrown out to both sides under the action of elastic force and may cause injury to personnel.

A fixing block is fixedly connected to the bottom of the protective housing, and a motor bracket is fixedly connected to the top of the fixing block. A fourth motor is fixedly connected inside the motor bracket, and the output end of the fourth motor is fixedly connected to a driving gear. The driving gear meshes with a hollow gear shaft which is rotatably connected to the fixing block. A second screw rod is sleeved inside the hollow gear shaft, and a detection cone is fixedly connected to the bottom of the second screw rod.

[0006] Further, a plurality of conductive balls are rotatably connected to the bottom of the pressure sensor.

[0007] Further, a plurality of rolling balls are rotatably connected to the outer wall of the detection cone, and the rolling balls are in contact with the inner surface of the pressure sensor.

[0008] Further, the adjustment unit includes four limiting plates. The tops of the limiting plates and the bottom surface of the top of the side plate are fixedly connected. A positioning rod is rotatably connected between two of the limiting plates, and a first screw rod is rotatably connected between the other two limiting plates. A third motor is fixedly connected to the side of the limiting plate away from the first screw rod, and the output end of the third motor is fixedly connected to the first screw rod. Adjusting rods are sleeved on both the first screw rod and the positioning rod. Adjusting grooves are formed on both sides of the adjusting rod, and a traction unit is slidably connected inside the adjusting groove. The bottom of the traction unit is fixedly connected to a lifting unit, and the bottom of the lifting unit is fixedly connected to the detection unit.

[0009] Further, the clamping unit includes a fixing frame installed on the top of the sliding seat. Adjusting blocks are symmetrically and fixedly connected to the top of the fixing frame, and a second motor is fixedly connected to the bottom of the fixing frame. The output end of the second motor is fixedly connected to a second bidirectional screw rod. Adjusting plates are sleeved on both sides of the second bidirectional screw rod.

[0013] The present invention has the following beneficial effects: 1. In the present invention, since the detection cone moves within the pressure sensor and the moving distance of the detection cone can be controlled, the length of the detection cone exposed can be selected according to different puncture requirements. At the same time, there is no need to replace the detection cone or the pressure sensor during the detection process, which can prevent the staff from being injured when replacing the detection cone or the pressure sensor.

[0014] 2. In the present invention, the guide tube can blow air towards the pressure sensor, and the air will flow downward along the outer wall of the pressure sensor, and at the same time, a gas film is formed on the pressure sensor. When the air flows to the bottom of the pressure sensor, it can blow away the impurities on the surface of the heat-sealing cover tape during the downward movement of the pressure sensor. Due to the increase in the air flow distance, the air impact force at this time will also decrease, and it can also reduce the situation where the heat-sealing cover tape is deformed greatly due to air impact. And it continuously blows away impurities after the pressure sensor contacts the heat-sealing cover tape to ensure the cleanliness of the heat-sealing cover tape, thereby increasing the detection accuracy.

[0015] 3. In the present invention, since the adjusting plate moves through the second bidirectional screw and the clamping blocks on both sides will move the same distance, when the clamping surface is folded or broken, it will cause the clamping block on the other side to be unable to clamp stably, and at this time, the heat-sealing cover tape cannot be detected. Therefore, it can prevent the heat-sealing cover tape from breaking due to uneven force to ensure the safety of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-7 As shown, the present invention is a strength detection device for heat-sealing cover tape production, including a workbench 1. Symmetrically fixed to the top of the workbench 1 are fixed plates 12. On one side of the top of the workbench 1 is fixedly connected a first motor 11. The output end of the first motor 11 is fixedly connected to a first bidirectional screw 13. Both sides of the first bidirectional screw 13 are sleeved with sliding seats 14; Fixed to the top of the sliding seat 14 is a clamping unit 2; fixedly connected to the top of the workbench 1 is a side plate 15. A through groove 151 is opened at the top of the side plate 15. A sliding groove is opened in the through groove 151. The sliding groove is slidably connected to an adjusting unit 3. Fixed to the bottom of the adjusting unit 3 is a detection unit 4; The detection unit 4 includes a protective housing 41. A pressure sensor 43 is fixedly connected to the bottom of the protective housing 41. A blower 42 is fixedly connected to one side of the protective housing 41. One end of the blower 42 located inside the protective housing 41 is fixedly connected to a diversion pipe 421, and the diversion pipe 421 is used to blow air on the pressure sensor 43. A fixing block 44 is fixedly connected to the bottom of the protective housing 41. A motor bracket 441 is fixedly connected to the top of the fixing block 44. A fourth motor 45 is fixedly connected inside the motor bracket 441. The output end of the fourth motor 45 is fixedly connected to a driving gear 46. The driving gear 46 meshes with a hollow gear shaft 47. The hollow gear shaft 47 is rotatably connected to the fixing block 44. A second screw rod 48 is sleeved inside the hollow gear shaft 47. The bottom of the second screw rod 48 is fixedly connected to a detection cone 49.

[0021] In this embodiment, considering that when detecting the heat-sealing cover tape, multiple detections are carried out simultaneously. During the tensile test of the heat-sealing cover tape, a pressure or puncture test is carried out at the same time to detect the strength of the heat-sealing cover tape in the extreme state. In the prior art, when detecting the heat-sealing cover tape, air is blown on the heat-sealing cover tape, and impurities on the heat-sealing cover tape are blown away by the blowing to increase the detection accuracy. However, at this time, the heat-sealing cover tape is in a taut state. When air is blown on the heat-sealing cover tape, the heat-sealing cover tape will be impacted by the air, which may cause the heat-sealing cover tape to be deformed greatly under force and break. Considering that in the prior art, when performing the pressure test and the puncture test, the pressure sensor 43 and the detection cone 49 need to be replaced, and manual replacement is required. If the heat-sealing cover tape is touched and broken during the replacement, the heat-sealing cover tape may be thrown out to both sides under the action of elastic force, and may cause injury to personnel. When performing the tensile test, first place the heat-sealing cover tape on the clamping unit 2 and clamp it through the clamping unit 2. Then, by starting the first motor 11, the first motor 11 will drive the first bidirectional screw rod 13 to rotate. When the first bidirectional screw rod 13 rotates, it will drive the sliding seat 14 to move outwards. When the sliding seat 14 moves outwards, it will also drive the clamping unit 2 to move outwards. When the clamping unit 2 moves outwards, it will stretch the heat-sealing cover tape and make the heat-sealing cover tape taut. When performing the pressure test, the adjusting unit 3 can adjust the position of the detection unit 4, and different positions of the heat-sealing cover tape can be tested according to requirements. At this time, the lifting unit 34 can move the detection unit 4 downwards, and stop moving when the detection unit 4 touches the heat-sealing cover tape. At this time, the lifting unit 34 can further move the detection unit 4, and make the pressure sensor 43 apply pressure downwards on the heat-sealing cover tape. Due to the interaction of forces, when applying pressure on the heat-sealing cover tape, specific pressure data can also be obtained through the pressure sensor 43. Thus, the compressive and tensile tests in the taut state can be detected. When performing a puncture test, the fourth motor 45 is started, and the fourth motor 45 drives the drive gear 46 to rotate. When the drive gear 46 rotates, it drives the hollow gear shaft 47 to rotate. When the hollow gear shaft 47 rotates, the second screw 48 moves downward. At this time, the second gear drives the detection cone 49 to move downward. When a part of the detection cone 49 moves out of the pressure sensor 43, a puncture test can be performed on the heat-sealing cover tape. Since the detection cone 49 moves within the pressure sensor 43 and the moving distance of the detection cone 49 can be controlled, the exposed length of the detection cone 49 can be selected according to different puncture requirements. At the same time, there is no need to replace the detection cone 49 or the pressure sensor 43 during the detection process, which can prevent workers from being injured when replacing the detection cone 49 or the pressure sensor 43. This not only improves the safety of the equipment but also increases the flexibility of the equipment to a certain extent; When performing detection, the air can be transmitted to the guide tube through the blower 42, and the air can be blown onto the pressure sensor 43 through the guide tube. At this time, the air will flow downward along the outer wall of the pressure sensor 43, and at the same time, an air film will be formed on the pressure sensor 43. When the air flows to the bottom of the pressure sensor 43, part of the air will diffuse outward and part will gather inward, which can blow away the impurities on the surface of the heat-sealing cover tape during the downward movement of the pressure sensor 43. Due to the increase in the air flow distance, the air impact force at this time will also decrease, which can also reduce the situation where the heat-sealing cover tape is deformed greatly due to air impact, and continue to blow away the impurities after the pressure sensor 43 contacts the heat-sealing cover tape to ensure the cleanliness of the heat-sealing cover tape, thereby increasing the accuracy of detection.

[0022] Specifically, a plurality of conductive balls 431 are rotatably connected to the bottom of the pressure sensor 43.

[0023] In this embodiment, considering that the pressure sensor 43 may perform pressure detection on different parts of the heat-sealing cover tape, at this time, the pressure sensor 43 will move on the heat-sealing cover tape; through the arrangement of the conductive balls 431, the sliding friction can be converted into rolling friction when the pressure sensor 43 moves, thereby reducing the occurrence of the situation where the heat-sealing cover tape is broken due to friction. At the same time, the conductive balls 431 can be energized, and the insulation of the heat-sealing cover tape can be detected when the conductive balls 431 contact the heat-sealing cover tape.

[0024] Specifically, a plurality of rolling balls 491 are rotatably connected to the outer wall of the detection cone 49, and a rolling groove is formed on the inner surface of the pressure sensor 43, and the rolling groove contacts the rolling balls 491.

[0025] In this embodiment, considering that the detection cone 49 is suspended or in sliding contact when moving on the inner surface of the pressure sensor 43, suspension may cause an error in the angle of the detection cone 49, resulting in different test results for the puncture test and large data errors. Sliding contact will increase the loss. The setting of the rolling ball 491 can not only prevent the detection cone 49 from being suspended, but also prevent the detection cone 49 from directly contacting the pressure sensor 43. Therefore, when the detection cone 49 performs a puncture test, it can maintain the same axis, reduce data errors, and increase the accuracy of the test.

[0026] Specifically, the adjusting unit 3 includes four limiting plates 31. The top of the limiting plate 31 is fixedly connected to the bottom surface of the top of the side plate 15. A positioning rod 313 is rotatably connected between the two limiting plates 31, and a first screw rod 312 is rotatably connected between the other two limiting plates 31. A third motor 311 is fixedly connected to the side of the limiting plate 31 away from the first screw rod 312. The output end of the third motor 311 is fixedly connected to the first screw rod 312. The first screw rod 312 and the positioning rod 313 are both sleeved with an adjusting rod 32. Adjusting grooves 321 are formed on both sides of the adjusting rod 32. A traction unit 33 is slidably connected in the adjusting groove 321. The bottom of the traction unit 33 is fixedly connected to a lifting unit 34. The bottom of the lifting unit 34 is fixedly connected to the detection unit 4.

[0027] In this embodiment, considering that in the prior art, the position of the detection unit 4 cannot be adjusted when detecting the heat-sealing cover tape. At this time, only the center of the heat-sealing cover tape can be subjected to pressure and puncture tests. Since the clamping unit 2 in the prior art also stretches the heat-sealing cover tape through the first bidirectional screw rod 13, the position of the heat-sealing cover tape cannot be adjusted either. When the detection position needs to be adjusted, by starting the third motor 311, the third motor 311 will drive the first screw rod 312 to rotate. When the first screw rod 312 rotates, the adjusting rod 32 will move along the axial direction of the positioning rod 313. After the adjusting rod 32 moves to the specified position, the traction unit 33 is started. At this time, the traction unit 33 can move along the adjusting rod 32. After the traction unit 33 reaches the specified position, the lifting unit 34 is started. At this time, the height of the detection unit 4 can be adjusted through the lifting unit 34, and the detection unit 4 can be moved downward during detection to perform pressure, puncture, and insulation tests. The position of the detection unit 4 can be flexibly adjusted, and different positions of the heat-sealing cover tape can be detected according to the detection needs.

[0028] Specifically, the clamping unit 2 includes a fixing frame 21, the fixing frame 21 is installed on the top of the sliding seat 14, the top of the fixing frame 21 is symmetrically and fixedly connected with adjusting blocks 25, and the bottom of the fixing frame 21 is fixedly connected with a second motor 22; the output end of the second motor 22 is fixedly connected with a second bidirectional screw 23, both sides of the second bidirectional screw 23 are sleeved with adjusting plates 24, both sides of the adjusting plate 24 are fixedly connected with traction plates 26, the traction plates 26 are slidably connected with the inner surface of the adjusting blocks 25, the middle of the traction plates 26 is slidably connected with a limiting rod 251, the limiting rod 251 is fixedly connected with the adjusting blocks 25, and one end of the traction plate 26 far from the adjusting block 25 is fixedly connected with a clamping block 27.

[0029] In this embodiment, considering that both sides of the heat-sealing cover tape need to be clamped simultaneously during the tensile test, and it is necessary to ensure sufficient stability during clamping, and it is also necessary to ensure that the clamping surface will not be folded or damaged during clamping. Otherwise, uneven stress may occur during the stretching of the heat-sealing cover tape, resulting in fracture. When clamping the heat-sealing cover tape, first place the heat-sealing cover tape into the clamping block 27, and then start the second motor 22. The second motor 22 will drive the second bidirectional screw 23 to rotate. When the second bidirectional screw 23 rotates, the adjusting plates 24 will approach each other. When the adjusting plates 24 approach each other, they will drive the traction plates 26 to approach each other. When the traction plates 26 approach each other, they will drive the clamping block 27 to clamp the heat-sealing cover tape. After the heat-sealing cover tape is clamped, the heat-sealing cover tape can be stretched by the movement of the sliding seat 14. Since the adjusting plate 24 moves through the second bidirectional screw 23, and the clamping blocks 27 on both sides will move the same distance, when the clamping surface is folded or broken, the clamping block 27 on the other side will not be able to clamp stably, and at this time, the heat-sealing cover tape cannot be detected. Therefore, it can prevent the heat-sealing cover tape from breaking due to uneven stress to ensure the safety of the staff.

[0030] Specifically, flexible pads 271 are fixedly connected to the sides of the clamping blocks 27 that are close to each other.

[0031] In this embodiment, through the setting of the flexible pads 271, micro-deformation can occur during clamping. When encountering minor folding and breaking, the force can be evenly distributed by increasing the force-bearing area. Even if there are some impurities remaining on the surface of the heat-sealing cover tape, the flexible pads 271 can wrap them through micro-deformation to reduce the situation of the impurities scratching the heat-sealing cover tape during clamping.

[0032] Specifically, a clamping block 272 and a clamping groove 273 are respectively arranged on the sides of the clamping blocks 27 that are close to each other, and the clamping block 272 is fitted with the clamping groove 273.

[0033] In this embodiment, when clamping the heat-sealing cover tape, the clamping block 272 will enter the card slot 273. After the clamping block 272 enters the card slot 273, the clamping block 27 can be completely aligned, which can reduce the situation that the clamping surface becomes smaller due to the angular deviation of the clamping block 27, and can make the clamping more stable.

[0034] Specifically, limiting grooves 141 are symmetrically formed at the top of the workbench 1. A plurality of conductive contacts are arranged in the limiting grooves 141, and the limiting grooves 141 are slidably connected to the sliding seat 14.

[0035] In this embodiment, through the arrangement of the limiting grooves 141, the sliding seat 14 can slide in the limiting grooves 141, and the sliding seat 14 can be limited to prevent the angle of the sliding seat 14 from changing. At the same time, the angle of the clamping unit 2 can be prevented from changing. Through the arrangement of the conductive contacts, when the position of the sliding seat 14 changes, it will be recorded through the conductive contacts, and when the heat-sealing cover tape is subjected to tensile detection, the position where the conductive contacts are conductive with the sliding seat 14 will be recorded. The method of recording through the conductive contacts can obtain more accurate data and increase the accuracy of detection.

[0036] During use, First, when performing tensile detection, first place the heat-sealing cover tape on the clamping unit 2. When clamping the heat-sealing cover tape, first put the heat-sealing cover tape into the clamping block 27, and then start the second motor 22. The second motor 22 will drive the second bidirectional screw 23 to rotate. When the second bidirectional screw 23 rotates, the adjusting plates 24 will approach each other. When the adjusting plates 24 approach each other, the traction plates 26 will be driven to approach each other. When the traction plates 26 approach each other, the clamping block 27 will be driven to clamp the heat-sealing cover tape. After the heat-sealing cover tape is clamped, the heat-sealing cover tape can be stretched by the movement of the sliding seat 14. Since the adjusting plates 24 move through the second bidirectional screw 23, and the clamping blocks 27 on both sides will move the same distance, when the clamping surface is folded or broken, the clamping block 27 on the other side will not be able to clamp stably, and at this time, the heat-sealing cover tape cannot be detected. Therefore, it can prevent the heat-sealing cover tape from breaking due to uneven force, so as to ensure the safety of the staff. Through the arrangement of the flexible pad 271, micro-deformation can occur during clamping. When encountering small-scale folding and breaking, the force can be evenly distributed by increasing the force-bearing area. Even if there are some impurities remaining on the surface of the heat-sealing cover tape, the flexible pad 271 can wrap them through micro-deformation, reducing the situation that the impurities cut the heat-sealing cover tape during clamping. When clamping the heat-sealing cover tape, the clamping block 272 will enter the card slot 273. After the clamping block 272 enters the card slot 273, the clamping block 27 can be completely aligned, which can reduce the situation that the clamping surface becomes smaller due to the angular deviation of the clamping block 27, and can make the clamping more stable. Subsequently, by starting the first motor 11, the first motor 11 drives the first bidirectional screw 13 to rotate. When the first bidirectional screw 13 rotates, it drives the slide seat 14 to move outward. When the slide seat 14 moves outward, it also drives the clamping unit 2 to move outward. When the clamping unit 2 moves outward, it stretches the heat-sealing cover tape and makes the heat-sealing cover tape taut; Through the setting of the limiting groove 141, the slide seat 14 can slide in the limiting groove 141, and the slide seat 14 can be limited to prevent the angle of the slide seat 14 from changing. At the same time, the angle of the clamping unit 2 can be prevented from changing; through the setting of the conductive contact, when the position of the slide seat 14 changes, it is recorded through the conductive contact, and when the heat-sealing cover tape is stretched and detected, the position where the conductive contact is conductive with the slide seat 14 is recorded. The method of recording through the conductive contact can obtain more accurate data and increase the accuracy of detection.

[0037] Secondly, when the detection position needs to be adjusted, by starting the third motor 311, the third motor 311 drives the first screw 312 to rotate. When the first screw 312 rotates, the adjusting rod 32 moves along the axial direction of the positioning rod 313. After the adjusting rod 32 moves to the specified position, the traction unit 33 is started. At this time, the traction unit 33 can move along the adjusting rod 32. After the traction unit 33 reaches the specified position, the lifting unit 34 is started. At this time, the height of the detection unit 4 can be adjusted through the lifting unit 34, and the detection unit 4 moves downward during detection, and pressure, puncture, and insulation tests are performed; the position of the detection unit 4 can be flexibly adjusted, and different positions of the heat-sealing cover tape can be detected according to the detection requirements.

[0038] Finally, before the pressure and puncture tests are performed, the air is transmitted to the guide pipe through the blower 42, and the air is blown to the pressure sensor 43 through the guide pipe. At this time, the air flows downward along the outer wall of the pressure sensor 43, and at the same time, an air film is formed on the pressure sensor 43. When the air flows to the bottom of the pressure sensor 43, part of the air diffuses outward and part of it gathers inward. The impurities on the surface of the heat-sealing cover tape can be blown off during the downward movement of the pressure sensor 43. Due to the increase in the air flow distance, the air impact force at this time will also decrease, and the situation where the heat-sealing cover tape is deformed greatly due to air impact can also be reduced. After the pressure sensor 43 contacts the heat-sealing cover tape, the impurities are continuously blown off to ensure the cleanliness of the heat-sealing cover tape, thereby increasing the accuracy of detection; When performing a pressure test, the position of the detection unit 4 can be adjusted by the adjustment unit 3, and different positions of the heat-sealing cover tape can be tested according to requirements. At this time, the detection unit 4 can be moved downward by the lifting unit 34 and stopped when the detection unit 4 contacts the heat-sealing cover tape. At this time, the detection unit 4 can be further moved by the lifting unit 34, and the pressure sensor 43 can be moved downward to apply pressure to the heat-sealing cover tape. Due to the mutual action of forces, specific pressure data can also be obtained through the pressure sensor 43 when applying pressure to the heat-sealing cover tape. Thus, the compression and tensile tests under a tight state can be detected; When performing a puncture test, by starting the fourth motor 45 and making the fourth motor 45 drive the drive gear 46 to rotate. When the drive gear 46 rotates, it will drive the hollow gear shaft 47 to rotate. When the hollow gear shaft 47 rotates, the second screw 48 will move downward. At this time, the second gear will drive the detection cone 49 to move downward. When a part of the detection cone 49 moves out of the pressure sensor 43, the heat-sealing cover tape can be punctured. Since the detection cone 49 moves within the pressure sensor 43 and the moving distance of the detection cone 49 can be controlled, the length of the detection cone 49 exposed can be selected according to different puncture requirements. At the same time, there is no need to replace the detection cone 49 or the pressure sensor 43 during the detection process, which can prevent the staff from being injured when replacing the detection cone 49 or the pressure sensor 43. This not only improves the safety of the equipment but also increases the flexibility of the equipment to a certain extent; Through the setting of the conductive ball 431, the sliding friction can be converted into rolling friction when the pressure sensor 43 moves. Thus, the situation of the heat-sealing cover tape being broken due to friction can be reduced. At the same time, the conductive ball 431 can be energized, and the insulation of the heat-sealing cover tape can be detected when the conductive ball 431 contacts the heat-sealing cover tape; Through the setting of the rolling ball 491, not only can the detection cone 49 be prevented from hanging in the air, but also the detection cone 49 can be prevented from directly contacting the pressure sensor 43. Thus, the same axis can be maintained when the detection cone 49 performs a puncture test, which can reduce data errors and increase the accuracy of the test.
