Description

Technical Field

[0001] This invention relates to the field of electronic product testing equipment technology, specifically to a pressure testing device for electronic products. Background Technology

[0002] Electronic products are frequently subjected to pressure, compression, or localized stress during production, assembly, transportation, and use. For example, the screens, casings, corners, button areas, and internal components of products such as mobile phones, tablets, smartwatches, earphone cases, and circuit board assemblies may deform, crack, loosen, or malfunction due to external pressure. Therefore, during product manufacturing or inspection, it is necessary to conduct pressure tests on different areas of electronic products to determine their structural strength and assembly reliability.

[0003] In existing pressure testing methods for small electronic products, some still rely on manual pressing or simple manual holding. This method typically involves the tester directly pressing the area to be tested on the electronic product, or using a manual pressure lever or block to apply pressure. While this method is simple and low-cost, it heavily depends on manual operation, leading to problems such as difficulty in controlling pressure, inconsistent pressing force, and significant differences in operation between different testers, making it difficult to ensure consistent testing conditions for each instance.

[0004] Meanwhile, manual testing methods typically only allow for pressure testing of a single area. When multiple areas of an electronic product need to be tested, it requires repeatedly moving the product, adjusting the pressure holding position, or manually pressing multiple times, resulting in low testing efficiency. For electronic products that require comparing the pressure resistance of different locations, this method makes it difficult to quickly switch between multiple test areas.

[0005] Furthermore, existing manual pressure testing methods often struggle to achieve graded pressure testing. Testers rely primarily on feel to control the pressure applied, lacking a clear segmented triggering structure and a stable pressure output mechanism, which can easily lead to inaccurate results. Especially when different pressure levels need to be applied to the same test area, the manual pressure application is difficult to replicate, affecting the consistency and reliability of the test results.

[0006] Therefore, it is necessary to provide a pressure testing device for electronic products that can achieve stable pressure output through a pneumatic structure while retaining the convenience of manual triggering, and can perform different levels of pressure testing according to different pressing stages, while adapting to the array testing needs of multiple test areas. Summary of the Invention

[0007] The purpose of this invention is to provide a pressure testing device for electronic products to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a pressure testing device for electronic products, comprising a frame and a plurality of pneumatic triggering components disposed within the frame. The plurality of pneumatic triggering components are arranged in an array. Each pneumatic triggering component includes: a housing, a top cover, a deformation disc, a first airbag, a second airbag, a reset band, a button, a first support component, a second support component, and a partitioning component. The housing has an open top structure, with a through hole at the bottom. The top cover is disposed at the top of the housing, and has an air inlet and an air outlet. The deformation disc is disposed within the through hole and can bulge upwards or downwards. The first airbag is disposed above the deformation disc, has a cylindrical structure, and is adhered to the bottom surface of the top cover. The second airbag... The first airbag is positioned above the deformation disk. The second airbag has a ring-shaped structure and is concentrically positioned with the first airbag. The reset band is positioned between the top cover and the deformation disk to keep the deformation disk in an upward bulging state when there is no external force. The button is positioned above the top cover and can be pressed down in segments relative to the top cover. The button has an initial state, a first-stage pressing state, and a second-stage pressing state. The first support component is positioned at the corner of the top cover and is connected to the button to support the button and provide pressing reset force. The second support component is positioned on the top surface of the top cover and cooperates with the button to limit the upward movement distance of the button and realize the segmented positioning of the button. The partition component is positioned at the center of the top cover, and the bottom end of the partition component extends into the first airbag.

[0009] Preferably, the partitioning component includes: an outer cylinder, an inner core, a limiting groove, a limiting block, an outer air inlet, an inner air inlet, a first air hole, a second air hole, an air outlet, a third air hole, a fourth air hole, a fifth air hole, an extension tube, an auxiliary air hole, an air core, a fixing rod, and a top block. The outer cylinder is located at the center of the upper cover, and its bottom end extends into the interior of the first airbag. The inner core is inserted into the inner cavity of the outer cylinder and is connected to a button so that the inner core can move up and down relative to the outer cylinder with the button. The limiting groove is formed on the outer wall of the inner core, and the limiting block is formed on the inner wall of the outer cylinder and inserted into the limiting groove to restrict the rotation of the inner core relative to the outer cylinder. The outer air inlet is formed on the upper part of the outer wall of the outer cylinder and communicates with the air intake channel. The inner air inlet is formed on the outer wall of the inner core, and the inner air inlet and the outer air inlet are in the same direction, and the axial length of the inner air inlet is greater than the axial length of the outer air inlet. The first air hole is formed on the lower part of the outer wall of the inner core. The inner core has a second vent located on the lower part of its outer wall, and the second vent and the first vent are spaced 90 degrees apart along the circumference of the inner core. The air outlet is located on the outer wall of the outer cylinder and is connected to the exhaust channel. The third vent is located on the outer wall of the outer cylinder and is connected to the first airbag. The fourth vent is located on the outer wall of the outer cylinder and is connected to the first airbag. The fifth vent is located on the outer wall of the outer cylinder and is connected to the second airbag. An extension tube is connected to the fifth vent and passes through the outer wall of the first airbag and extends into the interior of the second airbag. An auxiliary vent is located on the bottom surface of the inner core, and an air core is located inside the auxiliary vent to open or close the auxiliary vent. A fixing rod is located on the bottom surface of the outer cylinder along the axial direction of the outer cylinder, and the top end of the fixing rod passes through the auxiliary vent and extends into the interior of the inner core. A top block is located on the outer wall of the top end of the fixing rod and is used to hold the air core in place when the inner core is in its initial state to open the auxiliary vent.

[0010] Preferably, the axial directions of the air outlet, the third air hole, and the fourth air hole are parallel to each other, the axial directions of the fifth air hole and the external air inlet are parallel to each other, the axes of the third air hole and the fifth air hole are perpendicular to each other, and the third air hole and the fifth air hole are located on the same horizontal plane.

[0011] Preferably, when the inner core is in its initial state, the outer air inlet and the inner air inlet are offset, the first air hole corresponds to the air outlet, the bottom outer wall of the inner core blocks the third, fourth, and fifth air holes, and the top block presses against the air core, causing the auxiliary air hole to open, so that the gas in the first air bag and / or the second air bag can enter the interior of the inner core through the auxiliary air hole, and be discharged through the first air hole, the air outlet, and the exhaust channel. When the inner core is in the first stage of pressing, the outer air inlet corresponds to the inner air inlet, the first air hole corresponds to the fourth air hole, the second air hole is sealed by the inner wall of the outer cylinder, the air outlet is sealed, and the top block is disengaged from the air core. The air core blocks the auxiliary air hole, so that external gas can enter the first airbag sequentially through the air inlet, outer air inlet, inner air inlet, first air hole, and fourth air hole. When the inner core is in the second stage of pressing, the outer air inlet corresponds to the inner air inlet, the first air hole corresponds to the third air hole, the second air hole corresponds to the fifth air hole, the fourth air hole is closed, and the air core blocks the auxiliary air hole so that external gas can enter the first air bag through the first air hole and the third air hole, and enter the second air bag through the second air hole, the fifth air hole and the extension tube.

[0012] Preferably, the first support assembly includes: a support base, a support rod, and a second spring. The support base is located inside the housing and has a hollow tubular structure. The support rod is inserted into the support base, and the top end of the support rod is fixedly connected to the button. The second spring is located at the bottom end of the support rod and contacts the inner bottom surface of the housing.

[0013] Preferably, the second spring includes a first elastic segment and a second elastic segment, the first elastic segment and the second elastic segment having different elastic coefficients, so that the button generates different pressing resistance in the first stage pressing state and the second stage pressing state.

[0014] Preferably, the second support component includes: a retaining plate, retaining holes, and retaining balls. The retaining plate is disposed on the top surface of the upper cover and located at the corner of the button. The vertical cross-section of the retaining plate is L-shaped. The retaining holes are opened on the vertical inner wall of the retaining plate, and the retaining holes are arranged in three layers along the vertical direction. The retaining balls are disposed on the side wall of the button and can be respectively inserted into the three layers of retaining holes. The three layers of retaining holes correspond to the initial state of the button, the first stage of pressing state, and the second stage of pressing state, respectively.

[0015] Preferably, multiple sealing elements are provided between the inner core and the outer cylinder. The multiple sealing elements are spaced apart along the axial direction of the inner core and are respectively located between adjacent air passages of the outer air inlet, inner air inlet, first air hole, second air hole, air outlet, third air hole, fourth air hole and fifth air hole, so as to limit the cross-flow of air between different air passages.

[0016] Preferably, a number of pneumatic triggering components are arranged in a nine-square grid, a sixteen-square grid, or a twenty-five-square grid within the frame. The air intake of each pneumatic triggering component is connected to the same main air intake channel, and the exhaust of each pneumatic triggering component is connected to the same main exhaust channel, so that the number of pneumatic triggering components can share the same external air source and be triggered independently.

[0017] The present invention provides a pressure testing device for electronic products, which has the following advantages: 1. This invention uses a button to trigger a pneumatic triggering component, allowing external gas to enter the first airbag and / or the second airbag. The airbag then pushes the deformation plate downwards, thus replacing the method of directly applying pressure by manual touch. The button is only used to trigger the air path switching, and the actual pressure is output by the airbag, which helps to improve the consistency and stability of pressure testing.

[0018] 2. The button of this invention has an initial state, a first-stage pressing state, and a second-stage pressing state. During the first-stage pressing, the first airbag inflates and pushes the deformation plate; during the second-stage pressing, the first and second airbags inflate together and push the deformation plate, thereby achieving different levels of pressure output and avoiding the problem that the pressure level in manual detection relies entirely on the operator's feel.

[0019] 3. In this invention, several pneumatic triggering components are arrayed within the frame, allowing selection of the appropriate pneumatic triggering component based on the different test areas of the electronic product. Compared to traditional manual testing, which requires frequent product movement or repeated adjustment of the pressing position, this device can more conveniently achieve single-point, multi-point, or regional pressure testing.

[0020] 4. The partitioning component can connect the first airbag and / or the second airbag to the exhaust channel in the initial state, and achieve exhaust through the auxiliary air hole, air core, fixing rod and top block; at the same time, the reset band can restore the deformation plate to the bulging state, which helps to reduce the problems of gas residue and insufficient reset, and improves the reliability of continuous testing.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-10 This invention provides a technical solution for a pressure testing device for electronic products. Its detailed connection method is a well-known technology in the field. The working principle and process are mainly described below. The specific operation is as follows.

[0025] This embodiment provides a pressure testing device for electronic products. The pressure testing device includes a base 1, a frame 2, a plurality of pneumatic triggering components 4, and an actuating component 5. The base 1 is used to support the frame 2, and the frame 2 is used to install the plurality of pneumatic triggering components 4 and the actuating component 5. The plurality of pneumatic triggering components 4 are used to selectively generate pneumatic driving force according to the test area, and the actuating component 5 is used to transmit the downward pressure generated by the pneumatic triggering components 4 to the corresponding test position of the electronic product.

[0026] In this embodiment, the base 1 has an overall U-shaped structure. The base 1 includes a bottom support and two side walls connected to both sides of the bottom support, with a U-shaped groove formed between the two side walls. The frame 2 is disposed in the U-shaped groove and can move up and down relative to the base 1 along the Z-axis to adjust the height of the pneumatic trigger component 4 and the actuator component 5 relative to the electronic product under test.

[0027] Grooves are provided on the two outer walls of the base 1, and the grooves extend along the height direction of the base 1. Two sliding grooves 33 are symmetrically provided on the inner wall of each groove, and the two sliding grooves 33 extend along the Z-axis and are parallel to each other. Sliding rods 31 are provided at both ends of the frame 2, and the sliding rods 31 are slidably disposed in the corresponding sliding grooves 33 on both sides of the base 1. Through the cooperation of the sliding rods 31 and the sliding grooves 33, the frame 2 can slide up and down along the base 1, while restricting the frame 2 from shifting or shaking in the horizontal direction, thereby ensuring the stability of the frame 2 during the lifting process.

[0028] Limiting plates 34 are provided at the ends of the two slide rods 31 on the same side away from the frame 2. The limiting plates 34 are used to restrict the card holder 35 from disengaging from the slide rods 31. The card holder 35 is slidably disposed on the two slide rods 31 on the same side, so that the card holder 35 can move horizontally along the axis of the slide rods 31. A first spring 37 is sleeved on the slide rods 31 and is located between the card holder 35 and the limiting plate 34. The first spring 37 is used to apply an elastic thrust to the card holder 35 in the direction of the groove of the base 1, so that the card holder 35 can maintain the tendency to move inward toward the card slot 32 when it is not moved by an external force.

[0029] Multiple slots 32 are provided on the two horizontal inner walls of the groove, and the multiple slots 32 are arranged at intervals along the height direction of the base 1. The position of the slot 35 corresponds to the slot 32. The slot 35 can be inserted into the slot 32 at the corresponding height position under the elastic action of the first spring 37, thereby locking the frame 2 at the corresponding height. By inserting the slot 35 into the slots 32 at different heights, the frame 2 can be adjusted in different vertical height positions. The slot 35 is provided with a push groove 36, which is used for the operator or a pusher to insert and drive the slot 35 to move horizontally. When it is necessary to adjust the height of the frame 2, the push groove 36 drives the slot 35 to move outward against the elastic force of the first spring 37, so that the slot 35 is removed from the current slot 32. Then the frame 2 can move up and down along the slide 33. When the frame 2 moves to the target height, the slot 35 is released, and the first spring 37 pushes the slot 35 to insert into the new slot 32, thereby relocking the frame 2.

[0030] The frame 2 is configured as a double-layer structure, including an upper installation area and a lower installation area. The upper installation area is used to install several pneumatic triggering components 4, which are arranged in an array within the frame 2, such as a nine-square grid, a sixteen-square grid, or a twenty-five-square grid. The lower installation area is used to install the actuating components 5, which are located below the pneumatic triggering components 4 and correspond to the position of the deformation disk 411 in the pneumatic triggering components 4, so that when the deformation disk 411 bulges downward, it can act on the corresponding actuating component 5.

[0031] In this embodiment, a main air intake channel and a main exhaust channel can be provided within the frame 2. The air intake channels 43 of several pneumatic triggering components 4 are respectively connected to the main air intake channel, and the exhaust channels 44 of several pneumatic triggering components 4 are respectively connected to the main exhaust channel. The main air intake channel is used to connect to an external air source, and the main exhaust channel is used to centrally exhaust the gas discharged by each pneumatic triggering component 4. With the above structure, each pneumatic triggering component 4 does not need to be connected to an external air source separately, and can be supplied with air through the same external air source, making the overall pipeline layout of the device more compact.

A through hole is provided at the bottom of the housing 41, preferably a circular through hole. The through hole is located in the middle area of ​​the bottom of the housing 41 and is used to install the deformation disk 411 and to provide clearance for the deformation disk 411 to bulge downward. The inner cavity of the housing 41 is used to accommodate the first airbag 48, the second airbag 49, the upper area of ​​the deformation disk 411, and the lower structure of the first support assembly 46.

A sealing gasket or sealing ring can be provided between the top cover 42 and the housing 41 to improve the sealing of the air passage area inside the housing 41. An air inlet 43 and an exhaust 44 are provided inside the top cover 42. The air inlet 43 is used to introduce an external air source into the pneumatic trigger assembly 4, and the exhaust 44 is used to discharge the gas in the airbag. The air inlet 43 and the exhaust 44 can extend horizontally along the inside of the top cover 42 and are respectively connected to the partition assembly 410.

[0035] The deformation disk 411 is disposed in the through hole at the bottom of the housing 41; the deformation disk 411 can be made of rubber, silicone, elastic plastic, elastic composite material or other materials that can produce elastic deformation; the edge area of ​​the deformation disk 411 is fixed to the hole wall of the through hole or the mounting edge at the bottom of the housing 41, and the middle area of ​​the deformation disk 411 can bulge upward or downward relative to the bottom of the housing 41; when the deformation disk 411 is not squeezed by the airbag, it is in the upward bulging state, and when it is squeezed by the first airbag 48 and / or the second airbag 49 above it, the middle area of ​​the deformation disk 411 can bulge downward to transmit displacement and pressure downward.

[0036] The first airbag 48 is disposed above the deformation disk 411; the first airbag 48 has a cylindrical structure and is adhered to the bottom surface of the upper cover 42; the first airbag 48 is preferably located above the middle part of the deformation disk 411, so that the first airbag 48 can mainly act on the central area of ​​the deformation disk 411 after inflation; the upper end of the first airbag 48 is fixedly connected to the bottom surface of the upper cover 42, and the lower end of the first airbag 48 is set towards the deformation disk 411; the first airbag 48 can adopt an elastic airbag, a thin film airbag or a flexible sealed bag structure, and the first airbag 48 has an inflatable cavity inside.

[0037] The second airbag 49 is positioned above the deformation disk 411. The second airbag 49 has a ring-shaped structure and is concentrically positioned with the first airbag 48. The second airbag 49 is arranged around the first airbag 48, and the upper end of the second airbag 49 can also be adhered to the bottom surface of the upper cover 42. The lower end of the second airbag 49 faces the deformation disk 411. The first airbag 48 is located inside the second airbag 49, and the second airbag 49 is located outside the first airbag 48. The two are independently positioned and are not directly connected to each other. The first airbag 48 and the second airbag 49 are respectively supplied with air through the partition component 410, so that the first airbag 48 and the second airbag 49 can participate in the action on the deformation disk 411 at different pressing stages.

[0038] A reset band 412 is disposed between the upper cover 42 and the deformation disk 411; one end of the reset band 412 is connected to the upper cover 42, and the other end is connected to the deformation disk 411; the reset band 412 can be an elastic band, elastic sheet, elastic rope, or other elastic traction component; the reset band 412 is used to pull the deformation disk 411 back to the bulging state after the first airbag 48 and / or the second airbag 49 is deflated; the reset band 412 can be one or multiple; when multiple are set, the multiple reset bands 412 can be evenly distributed around the center of the deformation disk 411 to ensure that the deformation disk 411 is subjected to balanced force when reset.

[0039] Button 45 is located above the upper cover 42; button 45 is located on top of the pneumatic trigger assembly 4, allowing the operator to press it from the outside; button 45 can be pressed down in segments relative to the upper cover 42, and button 45 has an initial state, a first-stage pressing state, and a second-stage pressing state; the middle part of button 45 is connected to the inner core 4102 of the partition assembly 410, so that when button 45 is pressed down, it can drive the inner core 4102 to move up and down relative to the outer cylinder 4101; the corner of button 45 is connected to the first support assembly 46 to ensure that button 45 remains stable during up and down movement and is not prone to tilting; button 45 also cooperates with the second support assembly 47 to form positioning for different pressing stages.

[0040] The first support assembly 46 is located at the corner of the upper cover 42 and is connected to the button 45. The first support assembly 46 supports the button 45 and provides a pressing and resetting force. The first support assembly 46 includes a support base 461, a support rod 462, and a second spring 463. The support base 461 is located inside the housing 41 and has a hollow tubular structure. The lower end of the support base 461 can be fixed to the inner bottom surface of the housing 41 or the inner wall support portion of the housing 41, and the upper end of the support base 461 extends toward the button 45. The support rod 462 is inserted into the support base 461 and can slide up and down along the axial direction of the support base 461. The top end of the support rod 462 is fixedly connected to the button 45, and the bottom end of the support rod 462 cooperates with the second spring 463.

[0041] The second spring 463 includes a first elastic segment and a second elastic segment, which have different elastic coefficients. The elastic coefficient of the first elastic segment can be smaller than that of the second elastic segment, so that the button 45 has a smaller pressing resistance in the first stage of pressing and a larger pressing resistance in the second stage of pressing. Through this segmented elastic structure, the operator can obtain a distinct two-stage pressing feel during the pressing process.

[0042] The second support component 47 is disposed on the top surface of the upper cover 42 and cooperates with the button 45. The second support component 47 is used to limit the upward movement distance of the button 45 and realize the segmented positioning of the button 45.

The retaining plate 471 is disposed on the top surface of the upper cover 42 and is located at the corner of the button 45. The vertical cross-section of the retaining plate 471 is L-shaped. A part of the retaining plate 471 is fixed to the top surface of the upper cover 42, and the other part extends vertically and is located on the side of the button 45.

[0048] An external air inlet 4103 is located on the upper part of the outer wall of the outer cylinder 4101 and is connected to the air inlet 43 inside the upper cover 42.

[0050] An air outlet 4107 is located on the outer wall of the outer cylinder 4101 and is connected to the exhaust channel 44. The air outlet 4107 is used to correspond to the first air hole 4105 when the inner core 4102 is in the initial state, so that gas can enter the exhaust channel 44 through the air outlet 4107. The third air hole 4108 is located on the outer wall of the outer cylinder 4101 and is connected to the first airbag 48. The fourth air hole 4109 is located on the outer wall of the outer cylinder 4101 and is also connected to the first airbag 48.

The axial direction of the fifth air hole 41010 is parallel to that of the outer air inlet 4103. The axes of the third air hole 4108 and the fifth air hole 41010 are perpendicular to each other, and the third air hole 4108 and the fifth air hole 41010 are located on the same horizontal plane. Through the above arrangement of air holes, the first air hole 4105 and the second air hole 4106 can correspond to different air holes on the outer cylinder 4101 when the inner core 4102 is in different vertical positions, thereby realizing the segmented switching of different air paths within the limited space of the outer cylinder 4101.

A gap is maintained between 41014 to allow gas to pass through; the top block 41013 is disposed on the top outer wall of the fixing rod 41012. The top block 41013 is used to press against the air core 41015 when the inner core 4102 is in the initial state to open the auxiliary air hole 41014; after the inner core 4102 moves down, the top block 41013 disengages from the air core 41015, and the air core 41015 can block the auxiliary air hole 41014 to prevent the gas inside the inner core 4102 from leaking through the auxiliary air hole 41014 when pressed.

[0054] Multiple seals can be provided between the inner core 4102 and the outer cylinder 4101. The multiple seals are spaced apart along the axial direction of the inner core 4102 and are respectively located between adjacent air passages of the outer air inlet 4103, the inner air inlet 4104, the first air hole 4105, the second air hole 4106, the air outlet 4107, the third air hole 4108, the fourth air hole 4109, and the fifth air hole 41010. The seals can be sealing rings, sealing sleeves, elastic sealing rings, or other sealing structures. By setting multiple seals, cross-contamination between different air passages can be limited, and the accuracy of air passage switching of the partition component 410 under different pressing positions can be improved.

[0055] The execution component 5 includes four telescopic rods 51 and four pressure heads 52; the first ends of the four telescopic rods 51 are respectively hinged to the four corners of the inner wall of the frame 2, and the second ends of the four telescopic rods 51 are respectively connected to the four pressure heads 52; the telescopic rods 51 can extend and retract along their length direction, and can produce a certain amount of telescopic deformation when subjected to force in the Z-axis direction, which is used to compensate for the height difference between the pressure head 52 and the surface of the electronic product, and reduce the local bias pressure generated when a single pressure head 52 contacts the electronic product first.

[0056] The first end of the telescopic rod 51 is connected to the frame 2 via a hinge shaft, hinge seat, or ball joint structure, enabling the telescopic rod 51 to adjust its angle relative to the frame 2; the second end of the telescopic rod 51 is connected to the corresponding pressure head 52, preferably via a hinge structure or a spherical connection structure, so that the pressure head 52 can make a slight angle adaptive adjustment when under pressure.

[0057] Four pressure heads 52 are respectively disposed at the second end of the four telescopic rods 51; the four pressure heads 52 can be used as independent pressure heads 52 in the separate state to apply pressure to different local areas of the electronic product; the sides of the four pressure heads 52 that are close to each other form an inner angle, and each pressure head 52 is provided with a quarter-hole at the inner angle; when the four pressure heads 52 are brought together and combined, the four quarter-holes together form a second mounting hole 55; the second mounting hole 55 is located at the center of the four pressure heads 52 after combination, and can be used to install a center positioning component or an integral pressure head 52 connector.

[0058] Each pressure head 52 has a first mounting hole 54 on its bottom surface; the first mounting hole 54 is used to install different types of contact heads, such as flat contact heads, circular contact heads, flexible contact heads, rubber contact heads or strip contact heads; by replacing the contact head installed in the first mounting hole 54, the actuator 5 can be adapted to different test positions such as electronic product screens, shells, corners, button areas or component areas.

[0059] The four pressure heads 52 can be fixed into a single pressure head 52 by the elastic band 53. The elastic band 53 can be arranged around the outer periphery of the four pressure heads 52, so that the four pressure heads 52 are brought closer together and form a combined structure under the tightening action of the elastic band 53. After the four pressure heads 52 are combined, they can be used as a large-area pressure head 52 to apply planar or regional pressure to electronic products. In order to improve the stability after combination, the four pressure heads 52 can also be provided with mutually cooperating positioning protrusions, positioning grooves, splicing surfaces or limiting steps, so that the four pressure heads 52 are not prone to relative misalignment after combination.

[0060] A first magnet 56 is provided at the center of the bottom surface of the deformation disk 411, and a second magnet 57 is provided at the top of each of the four pressure heads 52. The opposing surfaces of the first magnet 56 and the second magnet 57 are opposite magnetic poles, so that the deformation disk 411 and the pressure head 52 can form a separable follower connection through magnetic attraction. The first magnet 56 is used to attract the second magnet 57 at the top of the corresponding pressure head 52, so that when the deformation disk 411 bulges downward, it can drive the pressure head 52 to move downward. At the same time, when the deformation disk 411 resets, it helps to drive the pressure head 52 back to the initial position. The first magnet 56 and the second magnet 57 can be embedded in the deformation disk 411 and the pressure head 52, or they can be fixed by adhesive, press-fitting or snap-fitting.

[0061] The actuator 5 is located below several pneumatic triggering components 4. For pneumatic triggering components 4 arranged in a nine-square grid, the actuator 5 can be set below one or more pneumatic triggering components 4 and can cooperate with the deformation disk 411 at the corresponding position according to the test requirements. When a certain pneumatic triggering component 4 is triggered, its deformation disk 411 bulges downward and acts on the corresponding pressure head 52 below. When multiple pneumatic triggering components 4 are triggered at the same time, the multiple deformation disks 411 can act on the multiple pressure heads 52 respectively or act together on the combined overall pressure head 52.

[0062] The lower mounting area of ​​frame 2 can also be provided with a horizontal guide structure to allow the actuator 5 to be positioned below multiple pneumatic triggering components 4. The horizontal guide structure may include a transverse slide, a longitudinal slide, a guide hole, a positioning hole, or a positioning pin. The actuator 5 can be mounted on the horizontal guide structure via a sliding seat, allowing the actuator 5 to move within the horizontal plane of frame 2 and lock at the target position. Through this structure, the actuator 5 can correspond to pneumatic triggering components 4 in different positions, enhancing the adaptability of the device to electronic products of different sizes and in different test areas.

[0063] In this embodiment, the height adjustment structure of the base 1 is mainly used to adjust the initial height of the frame 2 relative to the electronic product under test; the pneumatic trigger component 4 is mainly used to control the gas to enter the first airbag 48 and the second airbag 49 through different pressing stages; the execution component 5 is mainly used to transmit the downward displacement and pressure generated by the deformation disk 411 to the corresponding position of the electronic product; the various parts of the structure are arranged in the following order from top to bottom in space: the button 45 is located above the upper cover 42, the partition component 410 is located in the center of the upper cover 42, the first airbag 48 and the second airbag 49 are located between the upper cover 42 and the deformation disk 411, the deformation disk 411 is located in the through hole at the bottom of the housing 41, the execution component 5 is located below the deformation disk 411, and the electronic product is located below the execution component 5 or on the corresponding support platform; the base 1 and the frame 2 are located on the outside and around the above structure, and are used to provide overall support, installation positioning and height adjustment.

[0064] Working principle: In use, the height of the frame 2 is first adjusted according to the thickness of the electronic product under test and the test position. The operator moves the card holder 35 horizontally along the slide bar 31 through the slot 36, causing the card holder 35 to exit the current slot 32. At this time, the frame 2 can move up and down along the Z-axis in the U-shaped groove of the base 1. When the frame 2 moves to the appropriate height, the card holder 35 is released, and the first spring 37 pushes the card holder 35 to reset, so that the card holder 35 is inserted into the slot 32 at the corresponding height position, thereby locking the frame 2 at that height position. In the above manner, the pneumatic trigger component 4 and the actuator component 5 maintain a suitable initial distance from the electronic product under test. After the electronic product under test is placed in the corresponding position below the execution component 5, the operator selects the corresponding pneumatic trigger component 4 to press as needed; several pneumatic trigger components 4 are arrayed in the frame 2, so a single pneumatic trigger component 4 can be selected according to the test area of ​​the electronic product, or multiple pneumatic trigger components 4 can be selected to achieve single-point, multi-point or regional pressure testing; When the pneumatic trigger assembly 4 is not pressed, the button 45 is in its initial state. At this time, under the elastic action of the second spring 463, the button 45 is in an upward position, the retaining ball 473 is inserted into the upper retaining hole 472 of the retaining plate 471, and the inner core 4102 is in an upward position along with the button 45. At the same time, the reset belt 412 pulls the deformation disk 411, causing the deformation disk 411 to be in an upward bulging state. At this time, the external air inlet 4103 and the internal air inlet 4104 are misaligned, and external gas cannot enter the interior of the inner core 4102. The first air hole 4105 and the air outlet 4107 are connected. Correspondingly, the third vent 4108, the fourth vent 4109, and the fifth vent 41010 are blocked by the bottom outer wall of the inner core 4102; and the top block 41013 at the top of the fixing rod 41012 presses against the air core 41015, causing the auxiliary vent 41014 to open; if there is residual gas in the first airbag 48 or the second airbag 49, the gas can enter the interior of the inner core 4102 through the auxiliary vent 41014, and then be discharged sequentially through the first vent 4105, the air outlet 4107, and the exhaust channel 44, so that the pneumatic trigger assembly 4 is in the exhaust reset state; When the operator lightly presses button 45, button 45 enters the first stage of pressing state; at this time, the first elastic segment of the second spring 463 is compressed, the ball 473 enters the middle hole 472 from the upper hole 472, and the inner core 4102 moves downward with button 45 to the first stage position; at this time, the outer air inlet 4103 corresponds to the inner air inlet 4104, the first air hole 4105 corresponds to the fourth air hole 4109, the second air hole 4106 is closed by the inner wall of the outer cylinder 4101, and the air outlet 4107 is closed; at the same time, the top block 41013 disengages from the air core 41015. The air core 41015 blocks the auxiliary air hole 41014, isolating the interior of the inner core 4102 from the bottom space of the outer cylinder 4101; external gas enters the outer air inlet 4103 through the air inlet 43, then enters the interior of the inner core 4102 through the inner air inlet 4104, and enters the first air bag 48 through the first air hole 4105 and the fourth air hole 4109 in sequence; after the first air bag 48 is inflated, it squeezes the deformation disk 411 downward, causing the deformation disk 411 to gradually bulge downward from the upper bulging state, thereby driving the lower actuator 5 to apply the first stage pressure to the electronic product under test; When a greater test pressure is required, the operator continues to press down on button 45, causing button 45 to enter the second stage of pressing. At this time, the second elastic segment of the second spring 463 is compressed, and the ball 473 moves from the middle layer hole 472 into the lower layer hole 472. The inner core 4102 continues to move downward to the second stage position. At this time, the outer air inlet 4103 corresponds to the inner air inlet 4104, the first air hole 4105 corresponds to the third air hole 4108, the second air hole 4106 corresponds to the fifth air hole 41010, the fourth air hole 4109 is closed, and the air core 41015 continues to block the auxiliary air hole 41014. After the external gas enters the inner core 4102, part of the gas enters the first airbag 48 through the first air hole 4105 and the third air hole 4108, and the other part of the gas enters the second airbag 49 through the second air hole 4106, the fifth air hole 41010 and the extension tube 41011. Since the second airbag 49 has a ring structure and is arranged around the first airbag 48, in the second stage, the first airbag 48 and the second airbag 49 are inflated together and squeeze the deformation disk 411 together, which increases the effective area of ​​the deformation disk 411, thereby generating a larger downward driving force, driving the actuator 5 to apply the second stage pressure to the electronic product. After the actuator 5 is subjected to the downward pressure of the deformation disk 411, the four pressure heads 52, connected and supported by the telescopic rod 51, act downward on the electronic product. If the four pressure heads 52 are in a separate state, they can apply pressure to different local positions of the electronic product. If the four pressure heads 52 are combined into a single pressure head 52 by the elastic band 53, they can collectively form a larger pressure surface for regional or planar pressure testing of the electronic product. During the pressure process, the telescopic rod 51 can expand and contract along its length to compensate for the pressure, allowing each pressure head 52 to adapt to the height difference on the surface of the electronic product and reduce local bias pressure. The first magnet 56 on the bottom surface of the deformation disk 411 and the second magnet 57 on the top of the pressure head 52 attract each other, allowing the pressure head 52 to follow the downward pressure and reset action of the deformation disk 411. When the operator releases button 45, the second spring 463 pushes button 45 upward to reset, and the retaining ball 473 sequentially disengages from the lower or middle retaining hole 472 and returns to the upper retaining hole 472. The inner core 4102 moves upward with button 45 to its initial state. At this time, the outer air inlet 4103 and the inner air inlet 4104 are misaligned again, and the air intake passage is disconnected. The first air hole 4105 re-aligns with the air outlet 4107, and the top block 41013 reopens the air core 41015, enabling the auxiliary... The vent 41014 is opened; the gas in the first airbag 48 and the second airbag 49 enters the inner core 4102 through the auxiliary vent 41014, and is discharged through the first vent 4105, the air outlet 4107 and the exhaust channel 44; as the first airbag 48 and the second airbag 49 are discharged, the reset belt 412 pulls the deformation disk 411 back to the bulging state, and the actuator 5 returns to the initial position under the magnetic attraction and the self-reset action of the telescopic rod 51, thus completing one pressure test process; When different areas of an electronic product need to be tested, different pneumatic trigger components 4 can be pressed. When multi-point testing is required, multiple pneumatic trigger components 4 can be pressed simultaneously or sequentially. Since the pneumatic trigger components 4 are arrayed and each air intake duct 43 can be connected to the same main air intake channel, and each exhaust duct 44 can be connected to the same main exhaust channel, multiple pneumatic trigger components 4 can share the same external air source, while also being able to achieve independent triggering of different areas according to the button 45. Through the first stage pressing and the second stage pressing of the button 45, tests of different pressure levels can also be performed at the same test position.
