Description

Technical Field

[0001] This utility model relates to the field of mobile phone testing equipment technology, specifically a hard compression testing machine for mobile phone testing. Background Technology

[0002] As a frequently used electronic device, the pressure resistance of the mobile phone's casing and screen directly affects the product's lifespan and safety. Therefore, it is necessary to conduct strict testing through a hard-compression testing machine during the production process to ensure that the product meets quality standards. As a core testing equipment in the downstream of the mobile phone production line, the hard-compression testing machine can simulate the pressure scenario of the mobile phone and accurately test its resistance to deformation and breakage. It is a key link in ensuring the quality of the product leaving the factory.

[0003] The problem with existing technology is that when testing mobile phones with existing hard compression testing machines, the mobile phone needs to be placed into the testing area manually, and after the test is completed, it needs to be removed manually before the next round of testing can be carried out. This not only results in poor testing continuity and is time-consuming and labor-intensive, but also poses a safety hazard. Since the operator needs to reach into the testing area when picking up and placing the mobile phone, if the equipment malfunctions or the start button is accidentally pressed, it is very easy to cause hand injury. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a hard-compression testing machine for mobile phone testing. This machine features automatic feeding and automatic workpiece positioning during the feeding process, improving testing efficiency and safety. It solves the problem that existing hard-compression testing machines require manual placement of the phone into the testing area, followed by manual removal before the next round of testing. This not only results in poor testing continuity and is time-consuming and labor-intensive, but also poses safety hazards. Since manual insertion into the testing area is necessary when handling the phone, hand injuries are highly likely if the equipment malfunctions or the start button is accidentally pressed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hard-compression testing machine for mobile phone testing, comprising a main body, wherein a feeding mechanism is provided within the inner cavity of the main body. The feeding mechanism includes a support frame, the bottom of which is fixedly connected to the main body of the equipment, and a rectangular groove is provided in the middle of the top. A first screw is provided in the inner cavity of the rectangular groove, and a movable plate is sleeved on the surface of the first screw and threadedly connected to the movable plate. Both sides of the movable plate are slidably connected to the inner wall of the rectangular groove, and positioning components are provided on the front and rear sides of the top. Transmission components are provided on the left and right sides of the two positioning components. The rear side of the first screw is rotatably connected to the inner wall of the rectangular groove, while the front side penetrates the rectangular groove and extends to the outer side of the rectangular groove. A servo motor is fixedly connected to the front side of the support frame, and extrusion grooves for use with the transmission assembly are opened on the left and right sides of the top. The output end of the servo motor is fixedly connected to the front side of the first screw. The front and rear sections of the inner cavity of the extrusion groove are inclined and symmetrical to each other, while the middle section of the inner cavity is horizontal.

[0006] As a preferred embodiment of the present invention, the positioning component includes two guide plates, the bottom of which is fixedly connected to the movable plate, and positioning plates are slidably connected to both sides of the opposite side, and rubber pads are fixedly connected to the opposite side of the two positioning plates.

[0007] As a preferred embodiment of this utility model, T-shaped grooves are provided on both the front and rear sides of the top surface of the movable plate, and T-shaped blocks are slidably connected to the inner cavity of the T-shaped grooves.

[0008] As a preferred embodiment of the present invention, the transmission assembly includes an L-shaped plate, the bottom of the vertical section of the L-shaped plate is fixedly connected to a T-shaped block, and the bottom of the horizontal section is fixedly connected to an extrusion column, the bottom of the extrusion column being located in the inner cavity of the extrusion groove and slidably connected to the inner wall of the extrusion groove.

[0009] As a preferred embodiment of this utility model, a second screw is provided on the side of the L-shaped plate near the positioning plate. One end of the second screw is rotatably connected to the positioning plate, and the other end passes through the L-shaped plate and extends to the inner side of the L-shaped plate, and is threadedly connected to the through point of the L-shaped plate.

[0010] As a preferred embodiment of this utility model, a toggle block is fixedly connected to the end of the second screw away from the positioning plate, and a nut is provided on the side of the toggle block opposite to the L-shaped plate.

[0011] In a preferred embodiment of this invention, the nut is sleeved on the surface of the second screw and threadedly connected to the second screw, and the side closest to the L-shaped plate is in contact with the L-shaped plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem of existing hard-compression testing machines requiring manual placement of mobile phones into the testing area and manual removal after testing before the next round of testing. This not only results in poor testing continuity and is time-consuming and labor-intensive, but also poses safety hazards. Since manual insertion into the testing area is required when picking up and placing mobile phones, hand injuries are easily caused if the equipment malfunctions or the start button is accidentally pressed. This invention achieves automatic feeding and automatic positioning of the workpiece during the feeding process, improving testing efficiency and safety.

[0013] 2. This utility model achieves mobile phone detection and positioning by setting up positioning components. The positioning plates on both sides are symmetrically distributed and, together with the sliding guide plate, ensure that the mobile phone is clamped in the detection center, which facilitates the equipment to perform detection. The rubber pads on the inside of the positioning plate are soft and non-slip, which increases the friction with the phone case to prevent the phone from sliding during the test, and also buffers the clamping force to avoid scratches on the phone case and damage to the screen due to pressure. The T-shaped block and the T-shaped groove slide together, limiting the movement of the L-shaped plate and the positioning plate to only the horizontal direction, ensuring smooth clamping action.

[0014] 3. This utility model achieves the linkage between feeding and positioning by setting a transmission component, and is compatible with mobile phones of different sizes. The cooperation between the inclined and horizontal sections of the extrusion column and the extrusion groove means that when the moving plate feeds the mobile phone, the extrusion column slides along the inclined section to drive the positioning plate to automatically clamp the mobile phone. After the inspection is completed, the workpiece is automatically released by sliding along the reverse inclined section. No additional control is required, and it is completed synchronously with the feeding action. Rotating the toggle block drives the second screw to rotate, which can adjust the distance between the two positioning plates to adapt to mobile phones with different screen sizes; After adjustment, tighten the second screw with a nut to prevent the positioning spacing from shifting due to vibration during the testing process.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-3 This is the first embodiment of the present invention, which provides a hard compression testing machine for mobile phone testing, including a main body 1, and a feeding mechanism 2 is provided in the inner cavity of the main body 1. The feeding mechanism 2 includes a support frame 21. The bottom of the support frame 21 is fixedly connected to the main body 1 of the equipment, and a rectangular groove 22 is opened in the middle of the top. A first screw 23 is provided in the inner cavity of the rectangular groove 22. A movable plate 24 is sleeved on the surface of the first screw 23 and threadedly connected to the movable plate 24. Both sides of the movable plate 24 are slidably connected to the inner wall of the rectangular groove 22, and positioning components 25 are provided on the front and rear sides of the top. Transmission components 26 are provided on the left and right sides of the two positioning components 25. The rear side of the first screw 23 is rotatably connected to the inner wall of the rectangular groove 22, while the front side penetrates the rectangular groove 22 and extends to the outer side of the rectangular groove 22. A servo motor 3 is fixedly connected to the front side of the support frame 21, while the left and right sides of the top are provided with extrusion grooves 4 that cooperate with the transmission assembly 26. The output end of the servo motor 3 is fixedly connected to the front side of the first screw 23; The front and rear sections of the inner cavity of the extrusion groove 4 are inclined and symmetrical to each other, while the middle section of the inner cavity is horizontal.

[0022] Specifically, by setting up feeding mechanism 2, the problem of having to manually place the mobile phone into the testing area when testing it in the existing hard pressure testing machine is solved. After the test is completed, the phone must be manually removed before the next round of testing can be carried out. This not only results in poor testing continuity and is time-consuming and labor-intensive, but also poses safety hazards. Since the operator needs to reach into the testing area when picking up and placing the phone, if the equipment malfunctions or the start button is accidentally pressed, it is very easy to cause hand injury. The new mechanism achieves automatic feeding and can automatically position the workpiece during the feeding process, thus improving testing efficiency and safety.

[0023] Furthermore, based on the size of the phone to be tested, the distance between the positioning components 25 is adjusted by the transmission component 26, and the phone is placed in the positioning area between the two guide plates 251. The servo motor 3 is started to drive the first screw 23 to rotate, which drives the moving plate 24 to move towards the detection area. During the movement, the transmission component 26 cooperates with the extrusion groove 4 to drive the positioning component 25 to automatically clamp the phone. After the moving plate 24 reaches the detection area, the extrusion column 262 is located in the horizontal section of the extrusion groove 4, the positioning component 25 remains in a clamped state, and the pressure mechanism of the main body of the equipment 1 is activated to complete the hard pressure test. After inspection, the servo motor 3 rotates in the opposite direction, the moving plate 24 resets, and the transmission component 26 drives the positioning component 25 to automatically release the workpiece, completing one inspection cycle. The two positioning components 25 alternately feed the workpiece, improving inspection efficiency, and no manual intervention is required in the inspection area throughout the process.

[0024] Example 2 In the second embodiment of this utility model, the positioning component 25 includes two guide plates 251. The bottom of the guide plate 251 is fixedly connected to the moving plate 24, and both sides of the opposite side are slidably connected to the positioning plate 252. The opposite side of the two positioning plates 252 is fixedly connected to the rubber pad 253.

[0025] T-shaped grooves 5 are provided on both the front and rear sides of the top surface of the movable plate 24, and T-shaped blocks 6 are slidably connected to the inner cavity of the T-shaped grooves 5.

[0026] Specifically, by setting up the positioning component 25, the mobile phone detection and positioning are realized. The positioning plates 252 on both sides are symmetrically distributed, and with the sliding guidance of the guide plate 251, the mobile phone is ensured to be clamped in the detection center, which facilitates the equipment to perform detection. The rubber pad 253 on the inner side of the positioning plate 252 is soft and non-slip, which increases the friction with the phone case to prevent the phone from sliding during the test, and also buffers the clamping force to avoid scratches on the phone case and damage to the screen due to pressure. The T-shaped block 6 and the T-shaped groove 5 slide together, limiting the movement of the L-shaped plate 261 and the positioning plate 252 to only the horizontal direction, ensuring smooth clamping action.

[0027] Furthermore, the transmission component 26 drives the T-shaped block to slide along the T-shaped groove, driving the positioning plate 252 to move horizontally along the sliding groove of the guide plate 251. The two positioning plates 252 move closer or further apart to clamp and release the mobile phone. When clamped, the rubber pad 253 on the inner side of the positioning plate 252 fits tightly with the mobile phone shell, increasing friction to prevent slippage, while buffering the clamping force to avoid scratches on the mobile phone shell and damage to the screen due to pressure. The guide plate 251 limits the positioning plate 252 to move only in the horizontal direction, ensuring that the mobile phone is clamped in the detection center.

[0028] Example 3 In the second embodiment of this utility model, the transmission assembly 26 includes an L-shaped plate 261. The bottom of the vertical section of the L-shaped plate 261 is fixedly connected to the T-shaped block 6, while the bottom of the horizontal section is fixedly connected to an extrusion column 262. The bottom of the extrusion column 262 is located in the inner cavity of the extrusion groove 4 and is slidably connected to the inner wall of the extrusion groove 4.

[0029] A second screw 7 is provided on the side of the L-shaped plate 261 near the positioning plate 252. One end of the second screw 7 is rotatably connected to the positioning plate 252, and the other end passes through the L-shaped plate 261 and extends to the inner side of the L-shaped plate 261, and is threadedly connected to the through point of the L-shaped plate 261.

[0030] The end of the second screw 7 away from the positioning plate 252 is fixedly connected to a toggle block 8, and a nut 9 is provided on the side of the toggle block 8 opposite to the L-shaped plate 261.

[0031] Nut 9 is fitted onto the surface of the second screw 7 and threadedly connected to the second screw 7, and the side closest to the L-shaped plate 261 contacts the L-shaped plate 261.

[0032] Specifically, by setting the transmission component 26, the linkage between feeding and positioning is realized, and it is adapted to mobile phones of different sizes. The cooperation between the extrusion column 262 and the inclined and horizontal sections of the extrusion groove 4, when the moving plate 24 feeds, the extrusion column 262 slides along the inclined section to drive the positioning plate 252 to automatically clamp the mobile phone. After the inspection is completed, it slides along the reverse inclined section to automatically release the workpiece. No additional control is required, and it is completed synchronously with the feeding action. Rotating the toggle block 8 drives the second screw 7 to rotate, which can adjust the distance between the two side positioning plates 252 to adapt to mobile phones with different screen sizes; After adjustment, tighten the second screw 7 with nut 9 to prevent the positioning distance from shifting due to vibration during the testing process.

[0033] Furthermore, when adjusting the positioning distance, loosen the nut 9, rotate the toggle block 8 to drive the second screw 7 to rotate. Since the second screw 7 is threadedly connected to the L-shaped plate 261, the rotational motion is converted into the horizontal movement of the positioning plate 252. Adjust the distance between the two positioning plates 252 to fit the mobile phone size, and tighten the nut 9 to lock the second screw 7. During feeding, the moving plate 24 drives the L-shaped plate 261 to move synchronously, and the extrusion column 262 slides along the inclined section of the extrusion groove 4, generating a horizontal component force to push the L-shaped plate 261 to move along the T-shaped groove 5, thereby driving the positioning plate 252 to clamp the mobile phone. During testing, the extrusion column 262 is located in the horizontal section of the extrusion groove 4, and the positioning plate 252 remains clamped. During reset, the extrusion column 262 slides along the reverse inclined section, and the L-shaped plate 261 drives the positioning plate 252 to release the machine.

[0034] Working principle: During testing, based on the screen size of the phone to be tested, first loosen the nut 9 of the transmission assembly 26, rotate the toggle block 8 to drive the second screw 7 to rotate. Since the second screw 7 is threadedly connected to the L-shaped plate 261, the rotational motion is converted into the horizontal movement of the positioning plate 252. Adjust the distance between the two positioning plates 252 so that the distance is slightly larger than the width of the phone to ensure that the phone can be placed stably. After the adjustment is completed, tighten the nut 9 to lock the second screw 7 to prevent the positioning distance from shifting due to vibration during the testing process. After adjustment, the operator places the mobile phone to be tested in the placement area between the two guide plates 251 of the positioning component 25 on the top front side of the moving plate 24, turns on the equipment control switch, and the servo motor 3 is powered on and runs. The output shaft drives the first screw 23 to rotate. Since the moving plate 24 is threadedly connected to the first screw 23 and is limited by the rectangular groove 22, the rotational motion is converted into the horizontal linear movement of the moving plate 24, which drives the mobile phone to be smoothly transported to the detection area of ​​the main body 1 of the equipment. When the moving plate 24 moves toward the detection area, the extrusion column 262 of the transmission assembly 26 slides along the front inclined section of the extrusion groove 4 of the support frame 21. The inclined section generates an inward horizontal component force, which pushes the L-shaped plate 261 to move toward the middle along the T-shaped groove 5 through the T-shaped block 6, thereby driving the two side positioning plates 252 to move closer together along the sliding groove of the guide plate 251. The rubber pad 253 on the inner side of the positioning plate 252 fits tightly against the phone casing, which increases friction to prevent the phone from sliding and buffers the clamping force to avoid scratches on the casing and damage to the screen due to pressure. When the moving plate 24 reaches the detection area, the extrusion column 262 slides to the horizontal section of the extrusion groove 4, the force disappears, the positioning plate 252 remains in a stable clamping state, and the mobile phone is clamped in the detection center, ensuring that the pressure mechanism acts on the central area of ​​the mobile phone. After the moving plate 24 reaches the preset detection position, the servo motor 3 stops running, the positioning component 25 remains clamped, the pressure mechanism of the main body 1 is activated, and pressure is applied to the mobile phone casing or screen according to the preset pressure value. The pressure sensor of the main body 1 collects and records the detection data in real time. After the hard pressure test is completed, the pressure mechanism resets, the servo motor 3 rotates in the opposite direction, driving the first screw 23 to rotate in the opposite direction, and the moving plate 24 resets to the initial position. During the reset process, the extrusion column 262 slides in the opposite direction along the inclined section of the rear end of the extrusion groove 4, generating a horizontal component force to the outside, pushing the L-shaped plate 261 and the positioning plate 252 away synchronously, automatically releasing the mobile phone. When the moving plate 24 returns to the initial position, the operator takes out the tested mobile phone, and at the same time, the mobile phone to be tested placed in the positioning component 25 on the other side enters the testing area, realizing continuous feeding, improving the continuity of testing, and the entire process does not require the operator to reach into the testing area of ​​the equipment, thus improving safety.

[0035] In summary, by setting up feeding mechanism 2, automatic feeding is achieved, and the workpiece can be automatically positioned during the feeding process, thus improving detection efficiency and safety.
