DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-6, an adjustable clamping device for testing a mobile phone motherboard comprises a base 1, the top of the base 1 is slidably connected with an anti-damage mechanism 2, the anti-damage mechanism 2 comprises a clamping plate 201, a clamping groove 202 is provided on the top of the clamping plate 201, a trigger plate 203 is fixedly connected to the inner side of the middle part of the clamping plate 201, an anti-damage spring 204 is fixedly connected to the bottom end of the clamping plate 201, a trigger switch 205 is fixedly connected to the top and bottom of the trigger plate 203, and an anti-damage lamp 206 is connected to the side end of the trigger switch 205. When clamping the motherboard, the side wall of the motherboard needs to be placed in the clamping groove 202 of the clamping plate 201 in the anti-damage mechanism 2. The anti-damage mechanism 2 can also be set on both sides at the same time as needed to improve the anti-damage effect. After the motherboard is placed, the motherboard is clamped. If the clamping force is too large, the motherboard will be bent. The locking plate 201 will move accordingly, thereby extending or compressing the anti-damage spring 204, and the locking plate 201 will reduce the bending deformation through the elastic force of the anti-damage spring 204, thereby preventing the mainboard from bending too much and causing the mainboard to bend and be damaged, thereby reducing damage during the test process, greatly increasing the smoothness of the mainboard test, and improving work efficiency. If the clamping force of the mainboard is too large, causing the mainboard to bend too much, the moving distance of the locking plate 201 will increase, thereby causing the trigger plate 203 to move a larger distance, and further, the trigger plate 203 will move upward or downward, thereby closing the trigger plate 203 and the trigger switch 205 and starting the anti-damage light 206. After the anti-damage light 206 is started, the staff can see it and can reduce the clamping force by controlling the electric push rod 303 to prevent the mainboard from being damaged due to excessive bending.
[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Two moving mechanisms 3 are arranged above the base 1, and the moving mechanism 3 includes a moving plate 301. A moving spring 302 is fixedly connected between the moving plate 301 and the base 1, and an electric push rod 303 is fixedly connected to the inner side of the moving spring 302. Three moving slideways 304 are opened on the top surface of the moving plate 301. After adjusting the state of the clamping plate 401, the electric push rod 303 can be controlled to retract, and then the mainboard is placed in the recessed part of the clamping plate 401 for clamping, and then the action of the electric push rod 303 is disconnected, so that the spring clamps the mainboard. If the clamping force is too large, the electric push rod 303 can be controlled to retract to reduce the clamping force.
[0027] See also Figure 1 , Figure 3 , Figure 4 and Figure 5Three clamping mechanisms 4 are arranged on the top of each of the moving mechanisms 3, and the clamping mechanisms 4 include a clamping plate 401, and a sliding plate 402 is fixedly connected to the bottom end of the clamping plate 401, and the sliding plate 402 is slidably connected to the inner side of the moving slide 304, and a clamping spring 403 is fixedly connected between the sliding plate 402 and the moving slide 304.
[0028] See also Figure 1 , Figure 2 and Figure 4 The movable plate 301 is slidably connected to the slide rod 305 , and the slide rod 305 is fixedly connected to the inner wall of the base 1 .
[0029] See also Figure 1-6 , a switching groove 404 is provided on the top of the clamping plate 401 in the middle, and a card plate 405 is slidably connected to the left and right sides of the switching groove 404, and a fixing plate 406 is fixedly connected to the top of the card plate 405, and a spring rod 407 is fixedly connected to the side end of the fixing plate 406, and a switching plate 408 is slidably connected to the middle of the switching groove 404, and a cover plate 409 is slidably connected to the top of the switching plate 408, and a slide slot hole 410 is provided on the top of the cover plate 409. When it is necessary to test the mobile phone motherboard, the clamping device can be adjusted according to the shape of the mobile phone motherboard. If the mobile phone motherboard is a regular rectangle, the top protrusion of the switching plate 408 can be toggled to make the top protrusion slide in the slide slot hole 410, so that the switching plate 408 moves and is aligned with the mobile phone motherboard. The card plate 405 is in a locked state, so that the card plates 405 on both sides slide inside the switching groove 404 and enter the locking holes, so that the three clamping plates 401 are locked and move together, so that the rectangular main board can be clamped. If the main board is an irregular rectangle, the switching plate 408 can be moved in the opposite direction to disengage the card plate 405 from the locked state, so that the card plate 405 moves toward the center of the switching groove 404 and moves out of the locking hole under the action of the spring rod 407, and then is retracted into the clamping plate 401. In this way, the three clamping plates 401 can move separately, so that the clamping plates 401 can clamp the irregular main board side walls of different widths, so that the force on the main board side walls is more uniform and stable. The number of clamping plates 401 can be changed as needed to further cope with main boards of various shapes.
[0030] See also Figure 3 and Figure 5 A locking hole is provided on the side wall of the clamping plate 401 near the middle of the clamping plate 401 on the left and right sides.
[0031] In summary, in the present invention, when it is necessary to test the mobile phone motherboard, the clamping device can be adjusted according to the shape of the mobile phone motherboard. If the mobile phone motherboard is a regular rectangle, the top protrusion of the switching plate 408 can be toggled to make the top protrusion slide in the slide slot hole 410, so that the switching plate 408 moves and is in a locked state with the card plate 405, so that the card plates 405 on both sides slide inside the switching slot 404 and enter the locking holes, so that the three clamping plates 401 are locked and move together, so that the rectangular motherboard can be clamped. If the motherboard shape is an irregular rectangle, the switching plate 408 can be moved in the opposite direction to be out of the locked state with the card plate 405, so that the card plate 405 Under the action of the spring rod 407, it moves toward the center of the switching slot 404 and moves out of the positioning hole, and then retracts into the clamping plate 401. In this way, the three clamping plates 401 can move separately, so that the clamping plates 401 can clamp the irregular mainboard side walls of different widths, so that the force on the mainboard side walls is more uniform and stable. The number of clamping plates 401 can be changed as needed to further cope with mainboards of various shapes. After adjusting the state of the clamping plates 401, the electric push rod 303 can be controlled to retract, and then the mainboard is placed in the recessed part of the clamping plate 401 for clamping, and then the action of the electric push rod 303 is disconnected to allow the spring to clamp the mainboard. If the clamping force is too large, the electric push rod 303 can be controlled to retract to reduce the clamping force.
[0032] In the utility model, when clamping the mainboard, the side wall of the mainboard needs to be placed in the clamping groove 202 of the clamping plate 201 in the anti-damage mechanism 2. The anti-damage mechanism 2 can also be set on both sides at the same time as needed to improve the anti-damage effect. After the mainboard is placed, the mainboard is clamped. If the clamping force is too large, the mainboard will bend and deform. At this time, the clamping plate 201 will move with it, thereby stretching or compressing the anti-damage spring 204, and then the clamping plate 201 reduces the bending deformation through the elastic force of the anti-damage spring 204, preventing the mainboard from bending too much and causing the mainboard to bend and be damaged. The damage is reduced during the test process, the smoothness of the mainboard test is greatly increased, and the work efficiency is improved.
[0033] In the utility model, if the clamping force of the mainboard is too great and causes the mainboard to bend too much, the moving distance of the clamping plate 201 increases, thereby causing the trigger plate 203 to move a larger distance, further causing the trigger plate 203 to move upward or downward, thereby closing the trigger plate 203 and the trigger switch 205 and starting the anti-damage light 206. After the anti-damage light 206 is started, the staff can see it and can reduce the clamping force by controlling the electric push rod 303 to prevent the mainboard from being damaged due to excessive bending. The anti-damage light 206 warns the staff and then reduces the force in time, so that the mainboard can be tested smoothly, thereby improving the efficiency of the mainboard test work and reducing the damage to the mainboard.
[0034] The standard parts used in the utility model can all be purchased from the market, and the special-shaped parts can all be customized according to the description and the drawings.
[0035] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
