Description

Technical Field

[0001] This application relates to the field of semiconductor packaging technology, and more specifically, to an aluminum foil bag sealing tensile strength detection system. Background Technology

[0002] In the semiconductor industry, finished central processing unit (CPU) BGAs are shipped in vacuum-sealed aluminum foil bags. This solves the problem of solder ball oxidation in BGA products and ensures reliability during testing after installation on motherboards at downstream semiconductor factories.

[0003] The BGA finished product packaging process typically includes: 1) BGA products are placed into vacuum aluminum foil bags; 2) the bags are placed on a vacuum sealing machine for vacuuming and sealing; 3) the operator manually tears the vacuum aluminum foil bag to verify the seal quality. However, manual verification of the seal quality is affected by factors such as gender and age, making it difficult to ensure the stability and reliability of the tearing force. Therefore, to address this issue, a vacuum aluminum foil bag tensile testing system has been introduced to verify the sealing quality of the vacuum aluminum foil bags.

[0004] However, existing vacuum aluminum foil bag tensile testing systems typically have the following problems:

[0005] 1. Insufficient friction on the clamping surface of the tensile testing machine fixture causes the aluminum foil bag inside the fixture to slide during tensile testing, affecting the accuracy of the tensile test data.

[0006] 2. The tensile testing machine clamps require manual operation to tighten and loosen, which makes the operation inconvenient when installing and removing the test aluminum foil bags.

[0007] 3. The tensile testing machine lacks safety protection measures. If the operator does not stay away from the machine while it is in motion, there is a safety risk.

[0008] 4. The original manufacturer's testing software interface cannot meet the actual recording needs of production. Utility Model Content

[0035] refer to Figures 1 to 3 This paper illustrates a tensile testing system for sealing aluminum foil bags, which is a tensile testing machine system.

[0036] In some embodiments, the aluminum foil bag sealing tensile strength testing system includes a frame 100, a fixed clamp 200, a movable clamp 300, a translation mechanism 400, and a control terminal 500. The fixed clamp 200 is disposed on and fixed relative to the frame 100. The movable clamp 300 is disposed on the frame 100 and is capable of moving up and down relative to the fixed clamp 200. The translation mechanism 400 is disposed on the frame 100 and connected to the movable clamp 300, and is used to drive the movable clamp 300 to move relative to the fixed clamp 200. The control terminal 500 is electrically connected to the translation mechanism 400, and is configured to control the translation mechanism 400 to control the movement parameters of the movable clamp 300. During use, the fixed clamp 200 and the movable clamp 300 are used to clamp the two sides of the aluminum foil bag seal 10, respectively. The translation mechanism 400, under the control of the control terminal 500, can move the movable clamp 300 relative to the fixed clamp 200, so that the movable clamp 300 and the fixed clamp 200 can stretch the aluminum foil bag seal 10. Furthermore, during the inspection process, the control terminal 500 can control the movement parameters of the movable clamp 300, such as movement distance, movement speed, and movement time, by controlling the translation mechanism 400.

[0037] In some embodiments, both the fixed clamp 200 and the movable clamp 300 have opposing first clamping blocks 310 and second clamping blocks 320, wherein the first clamping block 310 is provided with a first clamping surface 311, and the second clamping block 320 is provided with a second clamping surface 221. During use, by controlling the relative movement of the first clamping block 310 and the second clamping block 320, the first clamping surface 311 and the second clamping surface 221 can be moved closer to or further away from each other. Specifically, when the first clamping surface 311 and the second clamping surface 221 are close together, the aluminum foil bag seal 10 can be clamped; when the first clamping surface 311 and the second clamping surface 221 are far apart, the aluminum foil bag seal 10 can be released.

[0038] In some embodiments, the first clamping surface 311 and the second clamping surface 221 of both the fixed clamp 200 and the movable clamp 300 can be provided with anti-slip structures. This configuration can effectively increase the friction between the first clamping surface 311 and the second clamping surface 221, preventing the aluminum foil bag seal 10 from sliding or falling off within the clamp during clamping, thereby ensuring the accuracy of the tensile test data.

[0039] In some embodiments, the anti-slip structure can be one of a knurled structure, a textured structure, and a sprayed structure. In this embodiment, the anti-slip structure is preferably a knurled structure. The knurled structure can give the first clamping surface 311 and the second clamping surface 221 a higher roughness, which can effectively increase the friction between the first clamping surface 311 and the second clamping surface 221 and prevent slippage.

[0040] In some embodiments, both the fixed clamp 200 and the movable clamp 300 can be pneumatic clamps. That is, under the action of air pressure, the first clamping block 310 and the second clamping block 320 can move closer to each other to achieve a clamping action, and when the air pressure is removed, the first clamping block 310 and the second clamping block 320 can move away from each other to achieve a releasing action. It should be understood that in order to achieve air pressure control, both the fixed clamp 200 and the movable clamp 300 should be equipped with an air pressure control switch, such as a manual sliding valve. During use, the operator can operate (rotate or slide) the air pressure control switch to control the air supply or cut-off, thereby achieving clamping and releasing of the clamp. Compared with the prior art of manually operating a screw-on fixture to control clamping and releasing, this setup eliminates the need for configuring and operating (screwing) a screw-on fixture, and the control of the clamp is relatively simple, which is beneficial to improving the convenience of operation.

[0041] In some embodiments, both the first clamping block 310 and the second clamping block 320 can be pneumatically driven, or one of the first clamping block 310 and the second clamping block 320 can be fixedly installed while the other can be pneumatically driven. In this embodiment, both the first clamping block 310 and the second clamping block 320 are pneumatically driven.

[0042] In some embodiments, the maximum distance between the first clamping surface 311 and the second clamping surface 221 of the fixed clamp 200 / movable clamp 300 is no greater than 5 mm. That is, at the maximum opening, the distance between the first clamping surface 311 and the second clamping surface 221 is no greater than 5 mm. This setting can prevent operators from inserting their fingers between the first clamping surface 311 and the second clamping surface 221 when installing the aluminum foil bag seal 10, thereby preventing finger injuries when the clamp is tightened.

[0043] In some embodiments, the translation mechanism 400 may include a drive assembly 410 and an electrical control box 420. The drive assembly 410 is connected to the movable clamp 300 and is used to drive the movable clamp 300 to move according to drive commands. The electrical control box 420 is electrically connected to the drive assembly 410 and is configured to output drive commands based on operator input. This configuration allows the operator to operate the translation mechanism 400 to adjust the position of the movable clamp 300 relative to the fixed clamp 200, facilitating the operator to attach the aluminum foil bag seal 10 to both the fixed clamp 200 and the movable clamp 300.

[0044] In some embodiments, the drive assembly 410 may include a movable crossbeam 411 and a linear motor 412. The movable crossbeam 411 is movably mounted on the frame 100 and connected to the movable clamp 300. The linear motor 412 is mounted on the frame 100 and connected to the movable crossbeam 411, and is used to drive the movable crossbeam 411 to move up and down, so that the movable crossbeam 411 drives the movable clamp 300 to move up and down relative to the fixed clamp 200. This configuration enables the translation mechanism 400 to drive the movable clamp 300 to move.

[0045] In some embodiments, the electrical control box 420 is provided with control buttons for operation by an operator to output control commands. For example, the electrical control box 420 is provided with a first control button 421 and a second control button 422. The first control button 421 outputs a first control command when pressed by the operator, which causes the drive assembly 410 to drive the movable clamp 300 downward. The second control button 422 outputs a second control command when pressed by the operator, which causes the drive assembly 410 to drive the movable clamp 300 upward. This configuration enables the electrical control box 420 to output drive commands based on operator input.

[0046] In some embodiments, the control terminal 500 may include a host 510 and a display 520. The display 520 is used to present an operation interface, which includes a control module, a display module, and an input module. The control module is used by the operator to input control commands, such as up commands, down commands, test commands, pause commands, and end commands. The display module is used to display detection information, such as the maximum force in the first interval, the minimum force in the first interval, the average force in the first interval, and the maximum force. The input module is used for sample information, such as machine number, packaging line number, employee number, shift, production batch number, and production date.

[0047] In some embodiments, the detection system further includes a protective fence 600, which surrounds the frame 100 and isolates the control terminal 500 outside the frame 100. For example, the protective fence 600 can be made of acrylic sheet, which surrounds the top, left, right, back, and front of the frame 100, with the control terminal 500 located outside the protective fence 600. This arrangement requires operators to operate the control terminal 500 outside the protective fence 600 to perform detection, thus ensuring the personal safety of the operators.

[0048] In some embodiments, the protective fence 600 is provided with an access port 610, which is used by an operator to operate the fixed clamp 200 and the movable clamp 300 to clamp the two sides of the aluminum foil bag seal 10 respectively. For example, in a specific configuration, the access port 610 can be opened on the acrylic plate on the front of the frame 100, or the acrylic plate can be provided only at the upper third of the front of the frame 100 to form the access port 610. This configuration allows the operator to approach the machine through the access port 610 to install and remove the aluminum foil bag seal 10 and to maintain the machine.

[0049] In some embodiments, the protective fence 600 is equipped with a human body recognition device 620. The human body recognition device 620 is located at the operating port 610 and electrically connected to the control terminal 500. The human body recognition device 620 is used to send a sensing signal to the control terminal 500 when an operator approaches the operating port 610, so that the control terminal 500 controls the translation mechanism 400 to stop operating. This configuration can prevent operators from approaching the machine while it is running, avoiding safety hazards caused by operators being too close to the machine.

[0050] In some embodiments, the human body recognition device 620 may be one or more of a safety light curtain, a photoelectric sensor, a laser scanner, an ultrasonic sensor, a capacitive proximity sensor, and a magnetic switch. In this embodiment, the anti-slip structure is preferably a safety light curtain. When a person or object blocks the safety light curtain, the safety light curtain can generate a light curtain sensing signal that is fed back to the control terminal 500, causing the control terminal 500 to control the translation mechanism 400 to stop operating.

[0051] The aluminum foil bag sealing tensile testing system of this application embodiment can detect the sealing tensile force of aluminum foil bags. Furthermore, the clamping surface of the system's fixture is provided with an anti-slip structure to prevent the aluminum foil bag seal from sliding or falling off within the fixture during clamping, thereby ensuring the accuracy of the tensile test data.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this specification should be included within the protection scope of this application.
