[0002] The universal testing fixture for blister trays is a specialized tool used to test the strength, anti-static properties, and sealing performance of blister trays, which can improve testing efficiency and accuracy.

[0003] Traditional universal testing fixtures for blister trays have significant limitations in design. Their structure is usually customized for a single or specific range of blister trays, resulting in limited applicability. When testing blister trays of different specifications, it is necessary to frequently change the fixture or manually adjust the position of the clamp, which not only increases the complexity of operation but also easily affects the testing accuracy due to positioning deviation. Therefore, a universal testing fixture for blister trays is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the traditional universal testing fixture for blister trays is usually designed for a single or specific size range of blister trays, resulting in limited applicability. This utility model provides a universal testing fixture for blister trays.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A universal fixture for testing blister packs includes a base with two support legs fixedly mounted on each side. Four sets of linearly movable support rod assemblies are positioned on top of the base, arranged in pairs facing each other. A positioning component is located at the bottom of the base to fix the current position of the four support rod assemblies. Each support rod assembly has a clamping component that can move up and down to hold the blister pack. Each support rod assembly also has a limiting component to fix the current height of the corresponding clamping component. A linkage component on the base assists in the synchronous lifting and lowering of the four clamping components. A tensile testing machine for detecting the tensile force of the blister pack is mounted on the base.

[0006] Furthermore, the support rod assembly includes a strip groove, and the top of the base has four strip grooves. The bottom surface of each strip groove has a strip hole. A protrusion is movably installed inside each strip groove. The protrusion of each protrusion is movably installed inside the corresponding strip hole.

[0017] like Figure 1-6As shown, the universal fixture for testing blister packs includes a base 1, with two support legs 2 fixedly mounted on each side of the base 1. Four sets of linearly movable support rod assemblies 3 are arranged on top of the base 1, with the four sets of support rod assemblies 3 arranged in pairs opposite each other. Figure 1-3 As shown, specifically, the support rod assembly 3 includes a strip groove 301, and the top of the base 1 has four strip grooves 301. Each strip groove 301 has a strip hole 302 on its inner bottom surface. Each strip groove 301 has a protrusion 303 movably installed inside it. The protrusion of each protrusion 303 is movably installed inside the corresponding strip hole 302. Each protrusion 303 has a base plate 304 fixedly installed at its bottom and a U-shaped frame 305 fixedly installed at its top.

[0018] More specifically, the protrusion 303 is embedded in the strip groove 301 and the strip hole 302, the base plate 304 is attached to the bottom surface of the base 1 to prevent the protrusion 303 from tipping over, and the U-shaped frame 305 slides with the protrusion 303 to realize stepless position adjustment of the support rod assembly 3 in the horizontal plane, providing a continuously variable reference for clamping blister trays of different outer dimensions, smooth sliding and no shaking after positioning, ensuring uniform distribution of subsequent clamping force.

[0019] The bottom of the base 1 is provided with a positioning component 4 for fixing the current position of the four sets of support rod assemblies 3, such as... Figure 1 , 2 As shown in Figure 6, specifically, the positioning component 4 includes a bending rod 401. Two bending rods 401 are fixedly installed on the top of the base 1. An electric push rod 402 is fixedly installed inside each bending rod 401. An extrusion plate 403 is provided below the base 1. The output end of the electric push rod 402 passes through the base 1 and is fixedly connected to the extrusion plate 403.

[0020] More specifically, the two electric push rods 402 simultaneously drive the extrusion plate 403 to move upward, so that the extrusion plate 403 presses the four base plates 304 at one time, and uses friction to lock the four support rod assemblies 3 at the same time, avoiding the need to tighten the screws one by one by hand, realizing "one-click fixing", which shortens the changeover time.

[0021] Each set of support rod assemblies 3 is equipped with a clamping assembly 5 that can move up and down to hold the blister tray, such as Figure 1-5As shown, specifically, the clamping assembly 5 includes a lifting block 501. Each U-shaped frame 305 has a lifting block 501 movably installed inside it. Each U-shaped frame 305 has a limit hole 502 on both sides. Each limit hole 502 has a limit block 503 movably installed inside it. Each limit block 503 is fixedly connected to the adjacent lifting block 501. Each lifting block 501 has a side plate 504 fixedly installed on its side wall. Each lifting block 501 has a square plate 1 505 fixedly installed on its side wall. Each lifting block 501 has a square plate 2 506 fixedly installed on its side wall. Each square plate 2 506 is threaded with a bolt 507. Each bolt 507 has a clamping plate 508 fixedly installed at its bottom end.

[0022] More specifically, the lifting block 501 slides vertically within the U-shaped frame 305, the limiting block 503 cooperates with the limiting hole 502 to prevent deflection, the square plate one 505 and the square plate two 506 form an open slot, the edge of the blister tray is inserted and the bolt 507 is tightened, and the clamping plate 508 presses down on the edge of the tray to achieve adjustable clamping in the thickness direction.

[0023] Each set of support rod assemblies 3 is equipped with a limiting component 6 that can be used to fix the current height of the corresponding clamping assembly 5, such as Figure 1-5 As shown, specifically, the limiting component 6 includes a mounting block 601, the top of each U-shaped frame 305 is fixedly mounted with a mounting block 601, the side wall of each mounting block 601 is fixedly mounted with an electric actuator 602, and the output end of each electric actuator 602 is fixedly connected to a strip frame 603.

[0024] More specifically, the electric actuator 602 is fixed on the mounting block 601. When its output end retracts, the strip frame 603 presses against the lifting block 501 to form a rigid limit, which can be quickly locked at any height to ensure that the four clamping components 5 are in the same horizontal plane.

[0025] The base 1 is equipped with a linkage component 7 that enables the synchronous lifting of four sets of clamping components 5. The base 1 also houses a tensile testing machine 8 for detecting the tensile strength of the blister pack. Figure 1-2 As shown, specifically, the linkage component 7 includes a cross 701, a cross 701 is provided above the base 1, two bending frames 702 are provided above the base 1, each bending frame 702 is fixedly connected to the cross 701, and two round rods 703 are fixedly installed above the base 1, each round rod 703 is fitted with a linkage block 704, and each linkage block 704 is fixedly connected to the adjacent bending frame 702.

[0026] More specifically, when the bending frame 702 is moved up and down manually, the linkage block 704 on the round rod 703 slides synchronously, keeping the cross 701 horizontally raised and lowered. The cross 701 can be used to level the four lifting blocks 501 synchronously with one click. This mechanical linkage avoids the height inconsistency caused by point-by-point adjustment and shortens the changeover time.

[0027] In summary: Base 1 is stably placed on the tabletop via support legs 2; four sets of support rod assemblies 3 can slide linearly on base 1; positioning assembly 4 locks the four base plates 304 at once, enabling rapid centering of blister trays of different lengths and widths; clamping assembly 5 is adjustable up and down within support rod assembly 3; limiting assembly 6 pushes strip frame 603 to press lifting block 501 via electric push rod 2 602, ensuring consistent height at each clamping point; linkage assembly 7 uses cross 701 and bending frame 702 to synchronously raise and lower the four lifting blocks 501, avoiding tilting errors caused by manual point-by-point adjustment; tensile testing machine 8 directly pulls the clamped blister tray to complete the strength test.
