Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone quality detection, in particular to a device for detecting the quality of a mobile phone shell. Background Art

[0002] During the logistics and transportation process or when users are using portable electronic products, improper operation may cause them to be impacted and dropped. The resulting damage is one of the more prominent reasons for electronic equipment failure. Once an electronic product is dropped and hit, it will be subjected to a large impact. This collision dynamic load will cause the electronic product to undergo nonlinear dynamic reactions. The reaction process is complex and changeable, and the time is short. Therefore, for electronic products, the main detection method is free drop.

[0003] Most existing drop detection equipment uses a lifting box with a vacuum suction device to suck the phone case to a certain height, then let the phone fall freely. When the phone case contacts the material plate at the bottom, it collides with the phone case and finally tests the phone case and the phone functions. The whole process is recorded by a high-speed camera.

[0004] During the actual testing process, the four sides of the mobile phone casing are usually required to fully contact the material plate to obtain accurate data. However, due to different heights or mobile phone casings, the shape of the mobile phone may change in the air during the falling process, and thus the predetermined collision effect cannot be achieved when it contacts the material, wasting the experimental prototype and testing time.

[0005] To this end, we propose a device for detecting the quality of mobile phone casings. Summary of the Invention

[0016] Preferably, round rods are arranged in a circular array on the winding disk, the round rods are fixedly connected to the winding disk and there are at least eight round rods, and the pushing disk is provided with notches, which fit into the round rods.

[0017] Preferably, the rotating rod is located on one side of the pushing disk and is provided with a wire winding groove, the pushing disk is provided with a wire inlet and the wire inlet is connected to the wire winding groove, a wire winding rod is rotatably connected in the wire winding groove, one end of the wire winding rod is connected to a ratchet mechanism, and the ratchet mechanism is used to lock or unlock the wire winding rod.

[0018] Preferably, the gripping mechanism comprises:

[0020] Preferably, the clinging component comprises:

[0021] The clamping wheel is rotatably connected to the fixed arm, and gear 2 is fixedly connected on both sides of the clamping wheel.

[0027] The present invention has at least the following beneficial effects:

[0028] 1. The moving part is pushed by the pushing device, so that the moving part drives the blocking block at its end to move along the direction of the rotating rod. When the pressing part at the bottom of the blocking block contacts the pressing bar, it squeezes the spring part 2 in the direction of the spring part 2, thereby causing the spring part 2 to generate elastic potential energy. At the same time, the pushing part at the top of the blocking block separates from the winding disk. At this time, the winding disk moves rapidly along the rotating rod under the drive of the spring part. At the same time, the connecting rope on the winding disk moves to one side with the winding disk as a reference under the obstruction of the pushing disk. Until the winding disk is completely pulled out of the connecting rope, the grabbing mechanism cooperates with the mobile phone housing to perform free fall motion with an initial velocity of zero.

[0029] 2. The driving device drives the rotating rod to rotate, thereby resetting the mobile phone case that has not reached the appropriate angle of collision. The experimenter can readjust the angle of the mobile phone case through the gripping mechanism and prepare for the next release. This method can avoid the mobile phone case colliding with the collision material at an angle that is not set, which will cause inaccurate experimental data and damage to the experimental prototype;

[0030] 3. By opening a notch on the push disk, when the rotating rod drives the push disk to rotate, the notch on the push disk drives the round rod to rotate, thereby causing the winding disk to rotate. By arranging the round rods in a circular array on the winding disk, the connecting rope wrapped around the round rods is easier to be pushed out when it is pushed out by the push disk because the contact area between the round rods and the connecting rope is smaller.

[0031] 4. After adjusting the distance between the lifting shell and the collision material through the lifting mechanism, the ratchet mechanism can be controlled to drive the winding rod to wind up or release the connecting rope. When the lifting mechanism drives the lifting shell to lower, the experimenter can rotate the ratchet mechanism to drive the winding rod to wind the connecting rope, so that the connecting rope can reach the appropriate distance between the grabbing mechanism and the collision material when released. Vice versa, when the lifting mechanism drives the lifting shell to rise, the experimenter can unlock the winding rod through the ratchet mechanism, so that the winding rod releases the connecting rope, so that during the drop test, the length of the connecting rope can reach the appropriate distance between the grabbing mechanism and the collision material.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] To better understand the device for testing the quality of mobile phone casings provided in the embodiments of the present application, the following first briefly introduces existing mobile phone casing testing equipment. Existing equipment generally uses a manipulator or a nozzle device to lift the mobile phone to a certain height and adjust its shape to ensure that the angle of impact with the ground material meets the standard.

[0041] The following is a brief overview of the present application scheme. The mobile phone housing can be made to fall freely by means of the winding device 20 and the grabbing mechanism 40. At the same time, the camera device is used to observe the state of the mobile phone housing when it falls, and then the winding device 20 and the grabbing mechanism 40 are used to decide whether to terminate the drop test, thereby minimizing the waste of the experimental prototype.

[0042] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: a device for detecting the quality of a mobile phone shell, comprising:

[0043] A lifting shell 10 is provided with a lifting mechanism 11 on one side of the lifting shell 10, and the lifting mechanism 11 is used to drive the lifting shell 10 to move up and down;

[0044] A camera device, the camera device is used to shoot the mobile phone housing during its falling process;

[0045] It should be noted that the lifting mechanism 11 cooperates with the lifting housing 10 to change the height of the lifting housing 10, which belongs to the prior art and will not be described in detail here.

[0046] The winding device 20 is provided on the lifting housing 10 and includes:

[0047] A rotating rod 21 is rotatably connected to the lifting housing 10, and one end of the rotating rod 21 is fixedly connected to a push plate 22;

[0048] a winding disk 23 slidably connected to the rotating rod 21;

[0049] A spring member 24, one end of which is fixedly connected to the rotating rod 21 and the other end of which is fixedly connected to the winding disk 23;

[0050] The movable member 25 is slidably connected to the rotating rod 21. The movable member 25 is slidably connected to a positioning block 26. The upper end of the positioning block 26 is a pushing portion in the shape of a right triangle, and the lower end of the positioning block 26 is a pressing portion in the shape of a right trapezoid. A pressing strip 27 for abutting against the pressing portion is fixedly connected to the inside of the rotating rod 21. A second spring member 28 is provided between the positioning block 26 and the movable member 25. One end of the second spring member 28 is fixedly connected to the positioning block 26 and the other end is fixedly connected to the movable member 25. A pushing device 29 is provided on the end of the movable member 25 away from the positioning block 26.

[0051] A driving device 30 is provided on the lifting housing 10 and is used to drive the rotating rod 21 to rotate;

[0052] A grabbing mechanism 40, wherein a connecting rope 41 is provided between the grabbing mechanism 40 and the winding device 20, and the grabbing mechanism 40 is used to fix the mobile phone housing;

[0053] It should be noted that by fixing the mobile phone housing with the gripping mechanism 40, the driving device 30 drives the rotating rod 21 to rotate, and the rotating rod 21 drives the winding disk 23 to rotate, so that the connecting rope 41 is wound around the winding disk 23, the shape of the mobile phone housing is adjusted to meet the required collision angle, and the distance between the lifting shell 10 and the collision material is adjusted by the lifting mechanism 11;

[0054] After the preparation is completed, the movable member 25 is pushed by the pushing device 29, so that the movable member 25 drives the blocking block 26 at its end to move along the direction of the rotating rod 21. The pressing portion at the bottom of the blocking block 26 contacts the pressing bar 27, which squeezes the spring member 28 in the direction of the spring member 28, thereby causing the spring member 28 to generate elastic potential energy. At the same time, the pushing portion at the top of the blocking block 26 separates from the winding disk 23. At this time, the winding disk 23 moves rapidly along the rotating rod 21 under the drive of the spring member 24. At the same time, the connecting rope 41 on the winding disk 23 moves to one side with the winding disk 23 as a reference under the obstruction of the pushing disk 22. Until the winding disk 23 is completely separated from the connecting rope 41, the grabbing mechanism 40 cooperates with the mobile phone housing to perform a free fall motion with an initial velocity of zero.

[0055] During the entire falling process, the camera device will cooperate with the control center to analyze the trajectory of the mobile phone shell in the air, and then predict whether it can reach the expected collision angle when colliding with the collision material. If it cannot reach it, the gripping mechanism 40 will not release the mobile phone shell, thereby preventing the mobile phone shell from colliding with the collision material. At the same time, the pushing device 29 drives the movable part 25 to move along the rotating rod 21, so that the pushing portion oblique edge of the top of the blocking block 26 contacts the winding disk 23 and squeezes the spring part 28 along the direction of the spring part 28 until the blocking block 26 completely passes the winding disk 23. The blocking block 26 is reset under the drive of the spring part 28, and the pushing device 29 pushes the winding disk 23 to return to its initial position. The rotating rod 21 is rotated by the driving device 30, thereby resetting the mobile phone shell that has not reached the appropriate collision angle. The experimenter can readjust the angle of the mobile phone shell through the gripping mechanism 40 and prepare for the next release. In this way, it can be avoided that the mobile phone shell does not collide with the collision material at the predetermined angle, causing inaccurate experimental data and damaging the experimental prototype.

[0056] Further as Figure 3 and Figure 4 As shown, it is worth mentioning that a circular array of round rods 231 is provided on the winding disk 23. The round rods 231 are fixedly connected to the winding disk 23 and there are at least eight round rods 231. A notch 232 is provided on the pushing disk 22. The notch 232 fits with the round rod 231.

[0057] It should be noted that, by providing a notch 232 on the pushing disk 22, when the rotating rod 21 drives the pushing disk 22 to rotate, the notch on the pushing disk 22 drives the round rod 231 to rotate, thereby causing the winding disk 23 to rotate. By arranging the round rods 231 in a circular array on the winding disk 23, when the connecting rope 41 wound on the round rods 231 is pushed out by the pushing disk 22, the connecting rope 41 will be more easily pushed out due to the smaller contact area between the round rods 231 and the connecting rope 41.

[0058] Further as Figure 4 As shown, it is worth noting that the rotating rod 21 is provided with a wire winding groove 241 on one side of the pushing disk 22, and the pushing disk 22 is provided with a wire inlet 242, and the wire inlet 242 is connected to the wire winding groove 241. A wire winding rod 243 is rotatably connected in the wire winding groove 241, and one end of the wire winding rod 243 is connected to a ratchet mechanism 244, and the ratchet mechanism 244 is used to lock or unlock the wire winding rod 243;

[0059] It should be noted that after the distance between the lifting shell 10 and the collision material is adjusted by the lifting mechanism 11, the ratchet mechanism 244 can be controlled to drive the winding rod 243 to wind up the connecting rope 41 or release the connecting rope 41. When the lifting mechanism 11 drives the lifting shell 10 to lower, the experimenter can rotate the ratchet mechanism 244 to drive the winding rod 243 to wind up the connecting rope 41, so that the connecting rope 41 cooperates with the grabbing mechanism 40 to reach a suitable distance from the collision material when released. Vice versa, when the lifting mechanism 11 drives the lifting shell 10 to rise, the experimenter can unlock the winding rod 243 through the ratchet mechanism 244, so that the winding rod 243 releases the connecting rope 41, so that during the drop test, the length of the connecting rope 41 can reach a suitable distance between the grabbing mechanism 40 and the collision material.

[0060] Further as Figure 5 and Figure 6 As shown, it is worth noting that the gripping mechanism 40 includes:

[0061] A connecting shell 46 is provided, within which two sets of fixed arms 42 are slidably connected. The top of the connecting shell 46 is fixedly connected to the end of the connecting rope 41. The ends of the fixed arms 42 are provided with a fastening assembly 43 for fixing the mobile phone housing. A motor 1 44 is provided in the middle of the connecting shell 46. The end of the internal rotating shaft of the motor 1 44 is fixedly connected to a gear 1 45. The side walls of the fixed arms 42 are each provided with teeth that mesh with the gear 1 45.

[0062] It should be noted that when the mobile phone case needs to be fixed, the mobile phone case needs to be placed between the fixing arms 42, and then the motor 1 44 is started to drive the gear 1 45 to rotate, so that the gear 1 45 drives the fixing arm 42 to move toward the middle of the connecting shell 46, so that the two sides of the fixing arm 42 clamp the mobile phone case with the clamping components 43, and vice versa. When the mobile phone case needs to be released, it is only necessary to start the motor 1 44 to drive the fixing arms 42 to quickly expand to both sides, so that the clamping components 43 are separated from the mobile phone case.

[0063] Further as Figure 5 As shown, it is worth noting that the clamping component 43 includes:

[0064] A clamping wheel 431 is rotatably connected to the fixed arm 42. Gear 2 432 is fixedly connected to both sides of the clamping wheel 431. A driving wheel 433 is rotatably connected to the fixed arm 42. A bevel gear 1 434 is fixedly connected to the inner wall of the driving wheel 433. A gear 3 435 meshing with gear 2 432 is fixedly connected to the outer wall of the driving wheel 433. A motor 2 436 is fixedly connected to the fixed arm 42. A bevel gear 2 437 is fixedly connected to the end of the internal rotating shaft of the motor 2 436. The bevel gear 2 437 meshes with the bevel gear 1 434.

[0065] It should be noted that the free fall test requires that the four sides of the mobile phone housing collide with the collision material, and also requires that the four corners of the mobile phone housing collide with the collision material. This can be achieved by controlling the second motor 436 to drive the second bevel gear 437 to rotate, the second bevel gear 437 drives the first bevel gear 434 to rotate, the driving wheel 433 drives the third gear 435 to rotate, the third gear 435 drives the second gear 432 meshing with it to rotate, and the pressing wheel 431 rotates accordingly;

[0066] It is worth noting that the user can control the rotation direction and angle of motor 2 436 to cooperate with the clamping wheel 431 to drive the mobile phone housing to form a certain angle with the horizontal plane, and then adjust to a suitable angle when it is necessary to test the four corners of the mobile phone housing and the collision material drop test.

[0067] Further as Figure 5 As shown, it is worth mentioning that the cross section of the clamping wheel 431 is concave, and the surface of the clamping wheel 431 is made of anti-slip material. By adopting a concave design for the cross section of the clamping wheel 431, the concave design can fit with the surface of the mobile phone casing, and then during the drop test, the mobile phone casing is not easy to deflect in the air, thereby ensuring the accuracy of the experiment.

[0068] According to the above embodiment, this solution also has embodiment 2: further as Figure 4 As shown, the pushing device 29 includes:

[0069] The electric cylinder 291, wherein the outer shell of the electric cylinder 291 is fixedly connected to the rotating rod 21, and the end of the telescopic rod inside the electric cylinder 291 is fixedly connected to the movable member 25;

[0070] It should be noted that by controlling the extension and retraction of the telescopic rod inside the electric cylinder 291, the movable part 25 can be driven to rotate inside the rotating rod 21. By fixedly connecting the outer shell of the electric cylinder 291 to the rotating rod 21, the electric cylinder 291 rotates synchronously with the rotating rod 21 during its rotation.

[0071] Further as Figure 3 As shown, it is worth noting that the driving device 30 includes:

[0072] The driving motor 31 has a housing fixedly connected to the lifting shell 10, and a roller is fixedly connected to the end of the rotating shaft inside the driving motor 31. A driving belt 32 is connected between the roller and the rotating rod 21. The driving motor 31 drives the driving belt 32 to rotate, and the driving belt 32 drives the rotating rod 21 to rotate.

[0073] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0074] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, all of which fall within the scope of protection of the present invention.
