Description

Technical Field

[0001] This application relates to the technical field of pressure holding test equipment, and more specifically, to a pressure holding test module. Background Technology

[0002] In the manufacturing of electronic products, such as mobile phones, tablets, automotive electronics, semiconductor packaging, and precision mechanical assembly, pressure holding testing is a crucial process. This process typically requires precisely positioning specific pressure-applying components, such as test probes, indenters, hot press heads, welding heads, and dispensing heads, at designated locations on the product under test, and applying preset pressure and holding time to verify the product's structural strength, sealing performance, connection reliability, welding quality, or functional characteristics.

[0003] In related technologies, automated and highly compatible multi-axis linkage pressure holding test modules are widely used to meet the testing needs of different models and specifications of products and improve production line efficiency. A typical pressure holding test module structure in existing technology usually includes: two Z-axis modules arranged parallel and symmetrically along the Y-axis. Each Z-axis module is equipped with a mover that can move independently or synchronously along the Y-axis. Between the movers of the two Z-axis modules, an X-axis module extending along the X-axis is jointly mounted and fixedly connected. By precisely controlling the synchronous operation of the two Z-axis modules, the entire X-axis module and its load can be driven to translate along the Y-axis. The X-axis module is also equipped with a mover that can move along the X-axis. A Z-axis module extending along the Z-axis is mounted on this X-axis mover. The movement of the X-axis module can drive the Z-axis module and its load to be precisely positioned along the X-axis. The Z-axis module is responsible for driving the pressure-applying component mounted at its end to perform vertical lifting and lowering movements.

[0004] Using the aforementioned technologies, the entire weight of the Z-axis module and its driven pressure-applying component, as well as the reaction force during the pressure application process, relies entirely on a single X-axis module and its mover for support and transmission. When the pressure-applying component is heavy or the applied test pressure is large, the X-axis beam will experience significant bending deformation under load. This deformation not only directly affects the absolute accuracy of Z-axis positioning but also causes the pressure point position to shift within the XY plane, severely reducing the repeatability and reliability of the test. Utility Model Content

[0005] In order to address the problem in related technologies where the pressure holding test module relies on a single X-axis module and its mover to bear the load, and when the pressure-applying component is heavy or the applied test pressure is large, the X-axis beam will undergo significant bending deformation under the load, affecting the pressure application accuracy, this application provides a pressure holding test module.

[0006] A pressure holding test module includes two module seats extending along the Y-axis. The two module seats are arranged in parallel and symmetrically. Each module seat has a sliding block slidably disposed on it, and the sliding block slides along the Y-axis. The sliding blocks of the two module seats are connected to a common driving source, which drives the two sliding blocks to reciprocate along the Y-axis. A support frame is erected and fixedly connected between the two sliding blocks. The support frame is provided with two X-axis modules arranged along the Z-axis. The two X-axis modules are arranged in parallel and symmetrically and both extend along the X-axis. The movers of the two X-axis modules are connected to a common Z-axis module, which extends along the Z-axis.

[0007] Preferably, the support frame includes a horizontally arranged base frame and a side frame connected to one side of the base frame. The side frame is arranged vertically. The base frame and the side frame are of the same length and extend in the X-axis direction. Two X-axis modules are arranged on the side of the side frame away from the base frame, and the two X-axis modules are respectively located on the upper and lower sides of the side frame. The two sides of the base frame along the X-axis direction are respectively locked to two sliding blocks.

[0008] Preferably, a plurality of first connecting posts are provided between the two sides of the bottom frame along the Y-axis direction, and the plurality of first connecting posts are evenly arranged along the length direction of the bottom frame; a plurality of second connecting posts are provided between the two sides of the side frame along the Z-axis direction, and the plurality of second connecting posts are evenly arranged along the length direction of the side frame.

[0009] Preferably, the number of the first connecting posts and the number of the second connecting posts are the same, and each first connecting post has a second connecting post aligned with it. The first connecting posts and the second connecting posts in each pair are arranged perpendicularly, and a third connecting post is arranged between them. One end of the third connecting post is connected to the first connecting post, and the other end of the third connecting post is connected to the second connecting post.

[0010] Preferably, the module base is provided with a slide rail extending along the Y-axis direction, and the slide rail is slidably engaged with the sliding block.

[0011] Preferably, the drive source includes a transmission mechanism, a drive shaft, and a servo motor. There are two transmission mechanisms, one of which is mounted on one module base and the other on another module base. Each transmission mechanism includes a drive wheel mounted on one end of the module base, a driven wheel rotatably mounted on the other end of the module base, and a timing belt fitted onto the drive wheel and the driven wheel. The drive wheels of the two transmission mechanisms are aligned and both drive wheels are fixed to the drive shaft. The servo motor is connected to the drive shaft to drive the drive shaft to rotate in both directions. The sliding block is connected and fixed to the timing belt.

[0012] Preferably, both the X-axis module and the Z-axis module are lead screw modules.

[0013] The beneficial technical effects of this application are as follows: By setting two parallel and symmetrical X-axis modules, the weight of the Z-axis module and its end pressure-applying component, as well as the reaction force during the pressure application process, are evenly distributed to the two support points. This effectively avoids the bending deformation problem caused by a single X-axis module under load, thereby ensuring the absolute accuracy of Z-axis positioning and the positional stability of the pressure point in the XY plane. Furthermore, the dual X-axis modules and the support frame form a rigid frame structure, significantly improving the overall bending stiffness and load-bearing capacity of the module. Compared to the existing single X-axis module design, this structure can withstand heavier pressure-applying components and greater test pressure without deformation, thus expanding the module's applicability. Using the same drive source to drive the two sliding blocks synchronously ensures high synchronization and facilitates cost reduction. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Reference Figure 1 and Figure 2A pressure holding test module includes two parallel and symmetrically arranged module seats 1, both extending along the Y-axis in their length direction. Each module seat 1 is equipped with a slide rail extending along the Y-axis, and a slidable sliding block 2 is mounted on the slide rail. The two sliding blocks 2 are connected to a drive source 3, which includes a servo motor 31, a drive shaft 32, and two symmetrically arranged transmission mechanisms 33. The two transmission mechanisms 33 are respectively mounted on the two module seats 1. Each transmission mechanism 33 includes a driving wheel 331, a driven wheel 332, and a synchronous belt 333. The drive shaft 32 is horizontally positioned, the driven wheel 332 is rotatably positioned at one end of the module seat 1, and the driving wheel 331 is positioned... At the other end of the module base 1, the synchronous belt 333 is sleeved on the driving wheel 331 and the driven wheel 332, and both driving wheels 331 are coaxially connected to the drive shaft 32. The servo motor 31 is connected to the drive shaft 32 to drive the drive shaft 32 to rotate in both directions. The rotation of the drive shaft 32 in both directions drives the driving wheels 331 to rotate in both directions, thereby driving the two synchronous belts 333 to rotate synchronously. The sliding block 2 is connected and fixed to the synchronous belt 333, so that the synchronous belt 333 drives the sliding block 2 to move back and forth along the length of the slide rail. The two sliding blocks 2 slide synchronously by a single drive source 3, which has high synchronization and reduces the use of an additional servo motor 31, thus reducing costs.

[0020] Reference Figure 1 and Figure 3 A support frame 4 is erected and fixedly connected between the two sliding blocks 2. The support frame 4 includes a horizontally arranged base frame 41 and a side frame 42 connected to one side of the base frame 41. Both the base frame 41 and the side frame 42 are rectangular frames. The length of the base frame 41 and the side frame 42 extends along the X-axis. The bottom side of the side frame 42 along the Z-axis is welded to one side of the base frame 41 along the Y-axis. The side frame 42 is of equal length to the base frame 41. The two sides of the base frame 41 along the X-axis are respectively locked to the two sliding blocks 2. The side frame 42 is far from the base frame 2. Two X-axis modules 5 extending along the X-axis direction are provided on one side of the frame 41, and the two X-axis modules 5 are located on the upper and lower sides of the side frame 42. The moving parts of the two X-axis modules 5 are connected to a Z-axis module 6. The Z-axis module 6 extends along the Z-axis direction and is connected to a pressure-applying component through the moving part of the Z-axis module 6. The two X-axis modules 5, together with the support frame 4, support the Z-axis module 6 and the pressure-applying component, and counteract the reaction force when pressure is applied. Both the X-axis module 5 and the Z-axis module 6 are lead screw modules, which makes their moving part displacement accuracy high and load strong.

[0021] Reference Figure 3To make the support frame 4 more stable, a number of first connecting columns 43 are arranged between the two sides of the bottom frame 41 along the Y-axis direction. The number of first connecting columns 43 are evenly distributed along the length of the bottom frame 41. A number of second connecting columns 44 are arranged between the two sides of the side frame 42 along the Z-axis direction. The number of first connecting columns 43 and second connecting columns 44 is the same. Each first connecting column 43 is aligned with a second connecting column 44. The first connecting column 43 and the second connecting column 44 aligned with each other are perpendicular to each other. A third connecting column 45 is arranged between the two. One end of the third connecting column 45 is connected to the first connecting column 43, and the other end of the third connecting column 45 is connected to the second connecting column 44. The first connecting column 43, the second connecting column 44 and the third connecting column 45 form a stable triangular support structure, which makes the support frame 4 more rigid and provides better load-bearing capacity.

[0022] The implementation principle of the pressure holding test module of this application is as follows: Servo motor 31 synchronously drives the sliding blocks 2 of the two module seats 1 through drive shaft 32, causing the entire support frame 4 and the X-axis module 5 and Z-axis module 6 on the frame to translate along the Y-axis. The two X-axis modules 5 synchronously drive their movers, causing the Z-axis module 6 to move along the X-axis direction. Because the Z-axis module 6 is supported by the two X-axis modules 5, the weight of the pressure-applying component and the test reaction force are distributed and transmitted to the upper and lower X-axis movers, and then evenly transmitted to the two sliding blocks 2 through the rigid support frame 4, significantly suppressing the bending deformation of the single beam; the Z-axis module 6 drives the pressure-applying component to rise and fall vertically to implement the pressure holding test. The dual X-axis support structure ensures that the XY plane positioning accuracy is not affected by the load during the pressure application process.
