Description

Technical Field

[0001] The invention relates to the technical field of mobile phone measurement, in particular to a batch detection device for mobile phone shells. Background Art

[0002] In the processing of mobile phone shells on the assembly line, the opening of side holes (such as volume button holes, power button holes, SIM card slot holes, etc.) is generally completed automatically by CNC machine tools in conjunction with punching machines. After the side holes are opened, the deviation of the holes needs to be detected. Only after the detection is qualified can the subsequent rough grinding, fine grinding and painting be carried out.

[0003] For the above-mentioned detection of the offset of the side hole of the housing, the detection means is usually carried out by CCD visual detection equipment, but the equipment is expensive, and its detection efficiency is poor for the detection of the side holes that are not on the same plane.

[0004] The existing patent application, with publication number CN109443128A, discloses "a device and method for detecting the position of the side hole of a mobile phone case", which positions the mobile phone case to be detected by a positioning mechanism, realizes the automatic adjustment of the positioning of the simple structure, and detects the mobile phone case to be detected by using the testing mechanisms at both ends of the positioning mechanism, so that the detection personnel can complete the detection of the side hole of the mobile phone case by pressing the test pins at both ends of the testing mechanism;

[0005] The above-mentioned detection device has insufficient automation on the one hand and also inadequacies in detecting the degree of hole deviation on the other hand. After detecting that the side hole is deviated, repair methods such as re-welding and re-drilling are adopted. The re-welding method usually needs to be adjusted accordingly according to the degree of deviation. Therefore, the detection of the degree of deviation of the side hole is of great reference significance for the subsequent re-welding repair method. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0041] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0042] Combination Figure 1-Figure 4A mobile phone shell batch detection device includes a positioning base 20 for clamping a mobile phone shell body 50, a side surface of the mobile phone shell body 50 is provided with a side hole 501 to be detected, a side edge of the positioning base 20 is provided with a displacement measurement mechanism 40 for detecting the displacement of the corresponding side hole 501, and a support component 30 for pushing the displacement measurement mechanism 40 toward the corresponding side hole 501 is fixedly connected to one side of the positioning base 20;

[0043] The offset measuring mechanism 40 includes a detection block 401 corresponding to the position of the side hole 501, and the detection block 401 is a wedge-shaped block corresponding to the shape of the side hole 501; it also includes a mounting cover 404 fixed to the side surface of the support component 30, and a spherical cover 403 is rotatably mounted inside the mounting cover 404. A horizontal docking column 402 pointing to the center of the circle and used to support the detection block 401 is provided on one side of the spherical cover 403. A contact component 405 is fixedly connected to the side of the spherical cover 403 facing the docking column 402. The contact component 405 is fixedly connected to the side of the spherical cover 403 facing the docking column 402. An angle measuring component 406 is provided in contact with one side of the component 405, and a disc 4031 is fixedly sleeved on the outer surface of the spherical cover 403 passing through the center of the circle vertically. A plurality of tension springs B4032 are connected in a ring shape to one side of the disc 4031. The tension springs B4032 pull the disc 4031 to enable the spherical cover 403 to support the detection block 401 horizontally to point to the side hole 501 through the docking column 402 in a static state. The lateral projection of the detection block 401 is at the exact center of the side hole 501. The side hole 501 includes a volume button hole, a power button hole, etc.

[0044] The above working principle and technical effect are: when in use, the control support component 30 pushes the installation cover 404, prompting the detection block 401 to move toward the side hole 501, so that the detection block 401 passes through the side hole 501. When the side hole 501 is not offset, the detection block 401 can just pass through the side hole 501. When the side hole 501 is offset, as the detection block 401 is pushed into the side hole 501, the inner wall of one side of the side hole 501 will push the surface of the detection block 401, prompting the spherical cover 403 to rotate, and the contact component 405 connected to the back side of the spherical cover 403 will also rotate by the same angle. By detecting the change in the contact position of the contact component 405 and the angle measuring component 406, the rotation angle of the spherical cover 403 can be measured, and then the offset distance L1 of the side hole 501 can be calculated;

[0045] The calculation process of the offset distance L1 of the side hole 501 is as follows: the support component 30 pushes the mounting cover 404 to the end position, the vertical distance from the center of the spherical cover 403 to the detection block 401 is l, and after the spherical cover 403 rotates, the contact component 405 and the angle measuring component 406 cooperate to measure, and the measured rotation angle is θ, so L1=lsi nθ, and the offset distance of the side hole 501 can be obtained.

[0046] Furthermore, the upper side of the positioning base 20 is fixedly connected to the first cylinder 101, and the positioning base 20 is provided with multiple ones along the conveying direction above the conveyor belt that conveys the mobile phone case body 50 at a fixed distance. The upper sides of the multiple first cylinders 101 are uniformly fixedly connected with a suspension 10, and the lower surface of the positioning base 20 is provided with a wedge-shaped positioning block 201 for calibrating the position of the mobile phone case body 50, and a pneumatic clamp 202 for fixing and clamping the inner wall of the side hole 501.

[0047] Specifically, the distance between two adjacent positioning bases 20 is equal to the distance between two adjacent mobile phone case bodies 50 on the conveyor belt;

[0048] By setting a positioning base 20 above the conveyor belt that conveys the mobile phone case body 50, the first cylinder 101 controls the lifting and lowering of the positioning base 20. The installation environment requirement is simple, and it can be suspended by the suspension 10. Then, the first cylinder 101 and the conveyor belt are coordinated with each other through the numerical control system. After the conveyor belt transports the mobile phone case body 50 to be directly below the positioning base 20, the first cylinder 101 is controlled to cause the positioning base 20 to descend to the upper side of the corresponding mobile phone case body 50, and the wedge-shaped positioning block 201 adjusts the position of the mobile phone case body 50 relative to the positioning base 20, so that the detection block 401 is opposite to the side of the corresponding side hole 501, and then the pneumatic clamp 202 is controlled to move out from the surface of the positioning base 20 to fix the position of the mobile phone case body 50 on the lower surface of the positioning base 20.

[0049] Furthermore, the support assembly 30 includes a fixing plate 301 fixed to one side of the positioning base 20, a second cylinder 302 is fixedly installed on the side of the fixing plate 301 away from the mobile phone case body 50, an output end of the second cylinder 302 passes through the fixing plate 301 to the other side and is fixedly connected to a push plate 303, and a mounting cover 404 is fixedly installed on the side of the push plate 303 close to the mobile phone case body 50.

[0050] Specifically, when a plurality of side holes 501 are opened on one side of the mobile phone case body 50, and a plurality of offset measuring mechanisms 40 are correspondingly arranged on one side, the pushing plate 303 is pushed by the second cylinder 302 to uniformly push the corresponding offset measuring mechanisms 40 in the direction of 501. The side holes 501 include sound expansion holes, which are often densely distributed. By fixing a dislocation base 304 on one side of the pushing plate 303, the dislocation base 304 supports the plurality of offset measuring mechanisms 40 to be displaced, so that the plurality of displaced offset measuring mechanisms 40 and the detection blocks 401 correspond one by one to one on one side of the plurality of densely distributed side holes 501, and implement measurement.

[0051] Combination Figure 4-Figure 8In the previous embodiment: an annular plate 4041 is vertically fixedly installed inside the mounting cover 404, an annular clamping seat A4042 is provided in the middle of the annular plate 4041, and an annular clamping seat B4043 is provided on one side of the mounting cover 404 close to the detection block 401;

[0052] The spherical cover 403 is rotatably arranged between the annular clamping seat B4043 and the annular clamping seat A4042. A plurality of open grooves 4033 are provided in an annular manner on the surface of the spherical cover 403 close to the annular clamping seat A4042. One end of a plurality of tension springs B4032 is fixedly connected to the side surface of the annular plate 4041. The angle measuring component 406 comprises an arc cover 4061 which is arranged concentrically with the spherical cover 403. The arc cover 4061 is fixedly installed on one side of the annular plate 4041. A plurality of metal rings 4062 are provided on one side of the arc cover 4061 close to the spherical cover 403. The plurality of metal rings 4062 are centered on the contact component 405, and the radius increases equidistantly outward. A wire B4063 which is conductively connected to the plurality of metal rings 4062 is provided on the outer side of the arc cover 4061. The arc cover 4061 A circuit board 4064 is fixedly installed on the outside, and multiple wires B4063 are connected to the circuit board 4064. The contact component 405 includes an elastic telescopic rod 4051 fixedly connected to one side of the spherical cover 403, and one end of the elastic telescopic rod 4051 close to the arc cover 4061 is fixedly connected to an arc-shaped metal joint 4052. A wire A4053 is inserted into the elastic telescopic rod 4051 and is conductively connected to the arc-shaped metal joint 4052, and the other end thereof passes through the open groove 4033 and the inner wall of the annular plate 4041 to be conductively connected to the circuit board 4064. The arc-shaped metal joint 4052 contacts the metal ring 4062 to form an electrical path, and the circuit board 4064 is used to detect the electrical signal in the metal ring 4062 where the path occurs and convert it into a deflection angle of the elastic telescopic rod 4051.

[0053] Specifically, when the spherical cover 403 is driven by the docking post 402 to rotate, the elastic telescopic rod 4051 will rotate in the opposite direction of the docking post 402, and the angle is the same. The arc surface of the arc cover 4061 is concentrically arranged with the spherical cover 403, so the vertical spacing of the surfaces is the same, so that the arc metal joint 4052 connected to one end of the rotating elastic telescopic rod 4051 can effectively contact the metal ring 4062. When measuring the rotation angle of the spherical cover 403, by determining the position of the last metal ring 4062 that contacts after the elastic telescopic rod 4051 rotates, the rotation angle of the spherical cover 403 can be calculated and converted, and then the value of the rotation angle θ of the docking post 402 can be obtained.

[0054] It should be noted that the error range of the θ value depends on the density of the multiple metal rings 4062. The dense multiple metal rings 4062 can effectively improve the accuracy of the θ value.

[0055] In order to determine the position of the arc-shaped metal joint 4052 and the last metal ring 4062 in contact, the circuit board 4064 is used for measurement. On the circuit board 4064, a plurality of sampling resistors 40643 are provided. The plurality of sampling resistors 40643 are connected in series with a plurality of wires B4063 one by one. The plurality of sampling resistors 40643 are connected in series with diodes 40644 respectively and then connected to the negative electrode of the transformer 40645. The positive electrode of the transformer 40645 is connected in series with the wire A4053 after being connected in series with a protective resistor 40646 and a capacitor 40647. An analog-to-digital converter 40642 is connected in parallel to one side of the sampling resistor 40643. A microcontroller 40641 is connected to one side of the analog-to-digital converter 40642 through a signal. The transformer 40645 is powered on, and when the arc-shaped metal connector 4052 comes into contact with the last metal ring 4062, current will flow through the sampling resistor 40643 corresponding to the wire B4063 connected to the metal ring 4062 on the circuit board 4064. After detecting the current passing through the sampling resistor 40643, the analog-to-digital converter 40642 converts the electrical signal into a data signal and sends it to the microcontroller 40641. The microcontroller 40641 measures the rotation angle θ of the elastic telescopic rod 4051 according to the angle represented by the corresponding metal ring 4062 matched with the signal, and then obtains the value of the rotation angle θ of the docking column 402. By substituting it into the above formula L1=lsi nθ, the offset distance L1 of the side hole 501 can be obtained.

[0056] Furthermore, the annular metal ring 4062 is evenly cut into multiple segments in an annular shape, and each segment of the metal ring 4062 is connected by a wire B4063.

[0057] Specifically, according to the position of the last energized metal ring 4062, the deflection direction of the docking column 402 can be reversely calculated, and then the offset direction of the side hole 501 can be obtained;

[0058] It should be noted that when the arc-shaped metal joint 4052 stops at the final position, it may come into contact with two metal ring 4062 segments or four metal ring 4062 segments at the same time. At this time, the angle and orientation take the middle value of the representative data of the multiple metal ring 4062 segments, which includes the angle and orientation.

[0059] Combination Figure 9-13 In the previous embodiment: the side of the detection block 401 away from the corresponding side hole 501 is provided with a matching outer ring 4013 with the same cross-sectional size as the side hole 501, and the side close to the side is an insertion surface 4014 with a geometrically scaled shape of the cross-sectional size of the side hole 501, and a pushing inclined surface 4012 is arranged around the two sides, and a reverse inclined surface 4015 in the opposite direction to the pushing inclined surface 4012 is provided on the side of the matching outer ring 4013 away from the pushing inclined surface 4012.

[0060] Specifically, the distance between the insertion surface 4014 and the reverse slope 4015 projected onto the side hole 501 is b, and the deviation range of the side hole 501 within b can be detected by the detection block 401. The distance l mentioned above is the length from the geometric center of the matching outer ring 4013 to the center of the spherical cover 403;

[0061] In the detection of the displacement of the side hole 501, the matching outer ring 4013 on the detection block 401 moves to align with the inner opening position of the non-displaced side hole 501. In the deflection plane, the width of the matching outer ring 4013 is the same as the width of the side hole 501 in the plane corresponding to the width, and both are counted as a. When the side hole 501 is displaced, as the detection block 401 deflects and enters, its matching outer ring 4013 rests on the inner wall of one side of the side hole 501, and the plane of the matching outer ring 4013 deflects in the displacement direction in the side hole 501, and its deflection angle is also θ. The width projection of the matching outer ring 4013 after deflection will be shortened in the corresponding width direction in the side hole 501 accordingly, and its shortened length is counted as L2. The precise displacement distance of the side hole 501 is counted as L, and its calculation formula is: L=L1+L2 / 2, wherein the calculation formula of L2 is: L2=aa*cosθ;

[0062] It should be noted that: the length of a is the cross-sectional length of the matching outer ring 4013 in the deflection plane of the detection block 401;

[0063] The thickness x of the side wall of the existing mobile phone case body 50 is between 2 and 3 mm, so the depth of the side hole 501 is x. In the matching outer ring 4013, the spherical cover 403 is the sphere center, l is the rotation radius, and within the interval covered by its rotation, the intersection model of the side wall with a thickness of x adjacent to the mobile phone case body 50 is the range of activity in which one side of the matching outer ring 4013 in deflection can contact the inner wall of the side hole 501. By controlling one side of the matching outer ring 4013 in deflection to maintain contact with the inner wall of the side hole 501, the quantitative lengths of a and l can be controlled not to change, eliminating the need for the matching outer ring 4013 to contact the inner wall of the side hole 501 beyond the inner side of the side hole 501, resulting in the need to adaptively change the length values ​​of a and l, thereby increasing the difficulty of calculation. Based on this, by constraining the conversion process and reducing variables, the conversion process can be simplified, further ensuring the accuracy of the side hole 501 offset measurement;

[0064] The vertical distance between the edge and the center of the above intersection model is y, so the length of y should be greater than the length of b, so that the detection block 401 can enter the side hole 501 while the deflected matching outer ring 4013 can also contact the inner wall of the side hole 501. Based on this, the relationship between y, l, and x is:

[0065]

[0066] Therefore, for the range of values ​​of x, the length of l must satisfy that y is greater than b.

[0067] The purpose of setting the reverse bevel 4015 is to reinforce the supporting strength of the outer edge of the matching outer ring 4013 and to prevent the detection block 401 from contacting the inner wall of the side hole 501 when the detection block 401 is tilted.

[0068] Combination Figure 4 In the previous embodiment: one side of the detection block 401 is coaxially and detachably connected to the docking column 402 through the connecting column 4011.

[0069] Specifically, the detection block 401 is detachably connected to the docking column 402 via the connecting column 4011 , so that for different side holes 501 , the detection block 401 and the docking column 402 corresponding to the side hole 501 can be assembled through the detachable connection.

[0070] Combination Fig.14 In the previous embodiment, a counterweight 4034 is fixedly provided in the cavity of the spherical cover 403 on one side symmetrical to the docking column 402 , and the counterweight 4034 is used to balance the detection block 401 and the gravity of the detection block 401 on one side of the spherical cover 403 .

[0071] Combination Fig.15 In the previous embodiment: the docking column 402 is movably inserted into the inner side of the spherical cover 403, a sleeve is provided on the inner side of the spherical cover 403 for the docking column 402 to be movably inserted, a spring A4021 is provided on the outer surface of the sleeve, and the docking column 402 is located at one end of the inner side of the spherical cover 403 and is fixedly connected with a protruding ring 4022, and the spring A4021 is used to pull the protruding ring 4022 against one side of the sleeve.

[0072] Furthermore, when the side hole 501 is too offset, resulting in the detection block 401 being unable to enter normally, as the push plate 303 is pushed forward, one side of the detection block 401 will be against the outer surface of the mobile phone case body 50, and at this time, one end of the docking column 402 can be retracted toward the inside of the spherical cover 403, so as not to affect the normal advancement of the push plate 303, thereby allowing other offset measurement mechanisms 40 on the push plate 303 to be detected normally; for the sleeve on the inner side of the spherical cover 403 for sleeve-mounting the docking column 402, the contact surfaces between it and the protruding circle 4022 are respectively provided with contact electrodes, and the connecting wires are connected to the circuit board 4064. As the docking column 402 is squeezed into the inner side of the spherical cover 403, the protruding circle 4022 will be separated from the sleeve on the inner side of the spherical cover 403, so that the contact electrodes therebetween are separated and the electrical signals are connected. At this time, the circuit board 4064 can obtain the situation that the side hole 501 is too offset according to the signal, so as to carry out targeted processing later.
