Description

Technical Field

[0001] This utility model relates to the field of cap strap carrier tensile testing technology, and more specifically, to an automatic device for testing the cap strap carrier tensile value. Furthermore, it also relates to a tensile testing system including the aforementioned automatic device for testing the cap strap carrier tensile value. Background Technology

[0002] In the existing technology, when testing the sealing tensile strength of the cover tape carrier, the workers usually manually operate the tape feeding machine to seal a section of the cover tape carrier before sending the sealed cover tape carrier to the tensile testing machine for tensile testing. This makes it impossible to detect the tensile strength of the cover tape carrier of each reel and greatly affects the tensile testing efficiency of the cover tape carrier.

[0003] In conclusion, how to effectively improve the efficiency and effectiveness of tensile testing of cover tape and carrier tape is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automatic testing device for the tensile strength of the cover tape and carrier tape, which can effectively improve the testing efficiency and effect of the tensile strength testing of the cover tape and carrier tape.

[0005] Another objective of this invention is to provide a tensile testing system that includes the above-mentioned automatic testing device for the tensile strength of the cover belt and carrier belt.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic testing device for the tensile strength of a cover strap carrier belt includes:

[0008] The first reel, used for winding the cover tape;

[0009] The second reel is used to wind the sealed carrier tape and the cover tape;

[0010] A sealing device for pressing or moving away from the carrier tape to seal the carrier tape to the cover tape or to loosen the sealed carrier tape;

[0011] A conveying device includes a conveying track for limiting the movement trajectory of the carrier belt and a conveying drive for driving the carrier belt and the cover belt to move within the conveying track. The sealing device and the first reel are provided above the conveying track, and the second reel is provided below the conveying track.

[0012] A tensile testing device includes a test track vertically mounted on the conveying track, a tensile sensor mounted at the bottom of the test track, an openable and closable retainer, and a test drive unit connected to the retainer. The retainer is used to clamp or release the cover strip, and the test drive unit is connected to the retainer to drive the retainer to move up and down along the test track.

[0013] The control device is connected to the sealing device, the conveying drive, the tension sensor, the fixing device, and the test drive.

[0014] In one embodiment, the sealing device includes a sealing blade and a sealing drive for driving the sealing blade to move up and down. The sealing drive is connected to the sealing blade and to the control device.

[0015] In one embodiment, the sealing drive includes a lifting motor.

[0016] In one embodiment, the conveying drive includes a stepper motor.

[0017] In one embodiment, a base is provided below the conveying device.

[0018] In one embodiment, the control device includes an acquirer for acquiring the detection data of the tension sensor, a judge for determining whether the detection data meets the requirements, and a display screen for displaying the detection data and the judgment result.

[0019] In one embodiment, the retainer includes two clamping wheels distributed vertically and an opening / closing drive, the opening / closing drive being connected to the upper clamping wheel to drive the upper clamping wheel closer to or away from the lower clamping wheel, and the cover strap being wrapped around the lower clamping wheel.

[0020] A tensile testing system, comprising the automatic testing device for the tensile value of the cover strap as described in any of the above claims.

[0021] When using the automatic testing device for the tensile strength of the cover tape and carrier tape provided by this utility model, firstly, the retainer is opened to loosen the cover tape, and the conveyor drive is operated to move the carrier tape and cover tape towards the second reel. After the sealing device seals the carrier tape and cover tape, the sealed carrier tape and cover tape are collected by winding the second reel. When it is necessary to test the tensile strength of the cover tape and carrier tape, the retainer can be opened again, and the sealing device can be raised and moved away from the sealed carrier tape and cover tape. Then, the conveyor drive is controlled to run in the opposite direction to move the sealed carrier tape and cover tape away from the second reel until the cover tape is close to the tensile strength sensor.

[0022] Afterwards, the control conveyor drive stops operating, causing the carrier belt to cease movement. Simultaneously, the control clamp closes and tightens the cover belt, and the test drive operates, driving the clamp to move the cover belt upwards along the test track. As the clamp moves the cover belt upwards along the test track, the tension sensor is close to the cover belt, which experiences an upward tension and gradually separates from the carrier belt. At this time, the tension sensor records the cover belt tension in real time and transmits the data to the control device. Finally, the control device processes and displays the data, allowing operators to determine whether the cover belt tension of each reel meets the requirements. For example, the control device can display the peel force at various positions on the carrier belt and generate a curve of peel force versus displacement to determine whether the test results meet the requirements.

[0023] In summary, the automatic testing device for the tensile strength of the cover tape and carrier tape provided by this utility model can effectively improve the testing efficiency and effect of the tensile strength test of the cover tape and carrier tape.

[0024] In addition, this utility model also provides a tensile testing system including the above-mentioned automatic testing device for the tensile strength of the cover belt carrier belt. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The core of this invention is to provide an automatic testing device for the tensile strength of the cover strap carrier belt, which can effectively improve the efficiency and effectiveness of tensile testing of the cover strap carrier belt. Another core aspect of this invention is to provide a tensile testing system that includes the aforementioned automatic testing device for the tensile strength of the cover strap carrier belt.

[0033] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of the automatic testing device for the tensile strength of the cover tape and the cover tape provided by this utility model, showing the structure of the sealing device for sealing the carrier tape and the cover tape. Figure 2 A schematic diagram of the carrier tape and cover tape after the sealing device has been loosened; Figure 3 This is a schematic diagram of the structure used by the tension sensor to test the tension value of the cover tape and the carrier tape.

[0034] This specific embodiment provides an automatic testing device for the tensile strength of a cover strap carrier belt, including:

[0035] First reel 1, which is used to wind cover tape 3;

[0036] The second reel 2 is used to wind the sealed carrier tape 4 and cover tape 3;

[0037] The sealing device 5 is used to press or move away from the carrier belt 4 to seal the carrier belt 4 with the cover belt 3 or to loosen the sealed carrier belt 4.

[0038] The conveying device 6 includes a conveying track 61 for limiting the movement trajectory of the carrier belt 4 and a conveying drive 62 for driving the carrier belt 4 and the cover belt 3 to move within the conveying track 61. A sealing device 5 and a first reel 1 are provided above the conveying track 61, and a second reel 2 is provided below the conveying track 61.

[0039] The tensile testing device 7 includes a test track 71 vertically mounted on the conveying track 61, a tensile sensor 72 located at the bottom of the test track 71, an openable and closable retainer 73, and a test drive unit connected to the retainer 73. The retainer 73 is used to clamp or loosen the cover strip 3. The test drive unit is connected to the retainer 73 to drive the retainer 73 to move up and down along the test track 71.

[0040] The control device, sealing device 5, conveying drive component 62, tension sensor 72, fixture 73, and test drive component are all connected to the control device.

[0041] It should be noted that the control device, through the tensile testing device 7 and the conveying device 6, in conjunction with software, can generate a peel force versus displacement curve for the peel force at various positions on the cover tape 3 of a certain length of carrier tape 4, and determine whether the test results meet the requirements. In practical applications, the shape, size, position, and type of the first reel 1, the second reel 2, the sealing device 5, the conveying drive component 62, the tensile sensor 72, the fixing device 73, the testing drive component, and the control device can be determined according to actual conditions and needs.

[0042] When using the automatic testing device for the tensile strength of the cover tape and carrier tape provided by this utility model, firstly, the control retainer 73 is opened to loosen the cover tape 3, and the conveyor drive 62 is controlled to run so that the carrier tape 4 and the cover tape 3 move towards the second reel 2. After the sealing device 5 seals the carrier tape 4 and the cover tape 3, the sealed carrier tape 4 and the cover tape 3 are then collected by winding the second reel 2. When it is necessary to test the tensile strength of the cover tape and carrier tape, the retainer 73 can be opened again, and the sealing device 5 can be raised and moved away from the sealed carrier tape 4 and the cover tape 3. Then, the conveyor drive 62 is controlled to run in the opposite direction so that the sealed carrier tape 4 and the cover tape 3 move away from the second reel 2 until the cover tape 3 is close to the tensile sensor 72.

[0043] Subsequently, the control conveyor drive 62 stops operating, causing the carrier belt 4 to cease movement. Simultaneously, the controllable retainer 73 closes and clamps the cover belt 3, and the test drive is activated to drive the retainer 73 to move the cover belt 3 upward along the test track 71. As the retainer 73 moves the cover belt 3 upward along the test track 71, the tension sensor 72 is close to the cover belt 3. The cover belt 3 experiences an upward tension and gradually separates from the carrier belt 4. At this time, the tension sensor 72 can record the cover belt carrier belt tension in real time and transmit the data to the control device. Finally, the control device performs data processing and display operations to allow operators to determine whether the cover belt carrier belt tension of each reel meets the requirements. For example, the control device can display the peel force at various positions of the cover belt 3 on the carrier belt 4 and generate a curve of peel force versus displacement to determine whether the test results meet the requirements.

[0044] In summary, the automatic testing device for the tensile strength of the cover tape and carrier tape provided by this utility model can effectively improve the testing efficiency and effect of the tensile strength test of the cover tape and carrier tape.

[0045] In one embodiment, the sealing device 5 includes a sealing blade and a sealing drive for driving the sealing blade to move up and down. The sealing drive is connected to the sealing blade and to a control device.

[0046] It should be noted that the sealing device 5 may also include a heating device for heating the sealing knife, so as to effectively seal the cover tape 3 and the carrier tape 4 using the high-temperature sealing knife. When a sealing operation is required on the cover tape 3 and the carrier tape 4, the sealing drive can be controlled to run, so as to drive the sealing knife to press the cover tape 3 and the carrier tape 4 together. When a test operation is required on the cover tape 3 and the carrier tape 4, the sealing drive can be controlled to run in reverse, so that the sealing knife moves away from the sealed cover tape 3 and the carrier tape 4.

[0047] In one embodiment, the sealing drive includes a lifting motor.

[0048] It should be noted that a lifting switch, control circuit, and transmission mechanism are also installed between the lifting motor and the sealing knife. When the operator presses the lifting switch, the control circuit transmits a signal to the lifting motor, the lifting switch closes, current flows to the lifting motor, the lifting motor starts to rotate, and the rotation of the lifting motor is converted into linear motion through the transmission mechanism (such as a gear transmission mechanism) to drive the sealing knife to rise or fall. When the sealing knife reaches the set height or is fully raised / lowered, the lifting switch is released, the current is cut off, and the lifting motor stops working. Of course, the sealing drive can also be set as an external drive structure, as long as the accurate lifting and lowering movement of the sealing knife is ensured.

[0049] In one embodiment, the conveying drive 62 includes a stepper motor. The stepper motor is a brushless DC motor capable of converting electrical pulse signals into angular displacement. The stepper motor has a fixed rotation angle; it rotates by a fixed angle for each pulse signal received, thereby achieving precise control and accurately controlling the movement of the carrier belt 4 and the cover belt 3.

[0050] It should be noted that the conveying device 6 may also include a conveying roller. By starting the stepper motor, the conveying roller can be driven to rotate, so as to realize the conveying operation of the carrier belt 4 and the cover belt 3. By controlling the stepper motor to rotate forward or backward, the carrier belt 4 and the cover belt 3 can be moved along the direction close to the second reel 2, or the carrier belt 4 and the cover belt 3 can be moved along the direction away from the second reel 2.

[0051] In one embodiment, a base 8 is provided below the conveying device 6. Furthermore, a support column 9 can be provided between the base 8 and the conveying device 6 to elevate the conveying device 6, facilitating the installation of components such as the second reel 2. Moreover, the conveying drive unit 62 can be positioned on the support column 9 away from the second reel 2, resulting in a more compact device structure.

[0052] In one embodiment, the control device includes an acquirer for acquiring data from the tension sensor 72, a judge for determining whether the data meets requirements, and a display screen for displaying the data and the judgment result. Specifically, the tension sensor 72 can detect and record the tension of the cover tape carrier belt in real time, then transmit the data to the acquirer, which in turn transmits it to the judge for data analysis and judgment processing. Finally, the monitoring data and judgment result are displayed on the screen so that the operator can determine whether the tension of the cover tape carrier belt after sealing on the second reel 2 meets the requirements.

[0053] In one embodiment, the retainer 73 includes two clamping wheels distributed vertically and an opening / closing drive. The opening / closing drive is connected to the upper clamping wheel to drive the upper clamping wheel closer to or away from the lower clamping wheel. The cover strap 3 is wrapped around the lower clamping wheel, as shown in the structure. Figures 1 to 3 As shown.

[0054] To further illustrate the use of the automatic testing device for the tensile strength of the cover belt provided by this utility model, the following example will be given.

[0055] 1. Control the fixing device 73 to open and release the cover belt 3 (i.e. control the opening and closing drive to make the upper clamping wheel move away from the lower clamping wheel to release the cover belt 3), and control the stepper motor to rotate counterclockwise so that the carrier belt 4 and the cover belt 3 both move to the left. After the high temperature sealing knife seals the cover belt 3 and the carrier belt 4, the sealed carrier belt 4 and the cover belt 3 are collected by winding the second reel 2.

[0056] 2. When it is necessary to test the tension of the cover tape and carrier tape, continue to open the retainer 73, and control the sealing device 5 to rise and move away from the sealed carrier tape 4 and cover tape 3. Then control the stepper motor to rotate clockwise, so that the sealed carrier tape 4 and cover tape 3 move to the right until the cover tape 3 is close to the tension sensor 72.

[0057] 3. Control the stepper motor to lock and fix the carrier belt 4 so that it cannot move. At the same time, control the retainer 73 to close and clamp the cover belt 3 (that is, control the opening and closing drive to make the upper clamping wheel approach the lower clamping wheel until the cover belt 3 is clamped), and control the test drive to drive the retainer 73 to move the cover belt 3 upward along the test track 71.

[0058] 4. When the retainer 73 moves the cover strip 3 upward along the test track 71, the tension sensor 72 is close to the cover strip 3. The cover strip 3 is subjected to an upward tension and gradually separates from the carrier belt 4. At this time, the tension sensor 72 can record the tension of the cover strip carrier belt in real time and transmit the detection data to the control device. Finally, the control device performs data processing and displays the data so that the operator can judge whether the tension of the cover strip carrier belt meets the requirements. For example, the control device can display the peeling force at each position of the cover strip 3 on the carrier belt 4 and generate a curve of peeling force versus displacement to judge whether the test results meet the requirements.
