Description

TECHNICAL FIELD

[0001] The present application relates to a shell hole position detection device, in particular a metal shell side hole position detection device. BACKGROUND

[0002] Compared with plastic shells, metal shells can be made thinner, can reduce the weight of the device, and obtain different surface textures. At present, some smart phones, notebook computers, tablet computers have adopted metal shells, and the side of these metal shells is provided with side holes, which correspond to electronic elements on the circuit board in the shell, such as power keys, volume adjustment keys, data line jacks, earphone jacks, speakers, pickups, etc.

[0003] Generally, the position of these side holes on the shell is required to be high, so as to accurately correspond to the electronic elements on the circuit board. Some existing detection devices position the shell, then push the detection rod around the shell to slide towards the shell, and judge whether the position of the side hole meets the standard by observing whether the detection rod is smoothly inserted into the corresponding side hole, and identify the side hole that does not meet the standard. There are problems of low detection efficiency and low identification accuracy. SUMMARY

[0004] The purpose of the present application is to provide a metal shell side hole position detection device to improve detection efficiency and improve identification accuracy.

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0006] A metal shell side hole position detection device, comprising a first base plate, a positioning frame, a detection rod, an information output device and a driver arranged on the top surface of the first base plate, the positioning frame can abut against the inner side wall of the shell, the detection rod corresponds to the side hole and can be inserted into the side hole and withdrawn from the side hole under the driving of the driver, the detection rod comprises a first end surface facing the side hole, the first end surface is provided with a first electrode and a second electrode, the first electrode and the second electrode are both electrically connected with the information output device, when the position of the side hole does not meet the standard, the first end surface will abut against the shell around the side hole during the process of driving the detection rod to insert into the side hole, at this time the first electrode and the second electrode are connected by the shell to generate a trigger signal, triggering the information output device to output prompt information.

[0007] In the scheme, the information output device is arranged, and the first electrode and the second electrode are arranged on the first end surface of the detection rod and electrically connected with the information output device. When the position of the side hole does not meet the standard, the first electrode and the second electrode are connected by the shell to generate a trigger signal, and the information output device is triggered to output prompt information, so that the side hole that does not meet the standard is automatically identified. The state of the detection rod does not need to be observed manually, and the position of the side hole does not need to be distinguished manually, the detection efficiency can be improved, observation errors can be avoided, and the identification accuracy can be improved. Moreover, the position of the side hole does not need to be detected by an additional sensor, the structure is simple, and the cost is low.

[0008] In some embodiments, the first electrode is a first ring body extending along the periphery of the first end surface, and the second electrode is a second ring body concentric with the first ring body.

[0009] In the scheme, the first electrode and the second electrode are constructed by two concentric ring bodies. When the side hole of the shell deviates in any direction, the first electrode and the second electrode are abutted and connected by the shell, and any deviation of the side hole of the shell can be effectively detected.

[0010] In some embodiments, the information output device is an indicator light, the position of the indicator light is located around the positioning frame, and the indicator light, the detected side hole and the detection rod correspond.

[0011] In the scheme, the indicator light is used to output prompt information, the position of the indicator light corresponds to the detected side hole, the side hole with a non-standard position is prompted by combining the state and position of the indicator light, and the structure is simple and the cost is low.

[0012] In some embodiments, the information output device includes:

[0013] A position information generation module configured to generate position information of the side hole based on a number of the first electrode or a number of the second electrode; and

[0014] A prompt information generation module configured to generate prompt information including the position information when the first electrode and the second electrode are connected.

[0015] In the embodiments, the information output device combines the number and state of the electrode to automatically generate prompt information, manual observation and identification of the position are not needed, the automation degree is higher, and the detection efficiency is higher.

[0016] In some embodiments, the information output device further includes a voice playing module configured to generate and play a voice based on the prompt information.

[0017] In the above embodiments, the prompts generated by the information output device are converted into voice playback through the voice playback module, so that staff can promptly detect the prompts and alarms even when they are not near the detection device.

[0018] In some embodiments, the information output device further includes a short message sending module, which is used to generate a reminder short message based on the prompt information and preset recipient information, and then send it.

[0019] In the above embodiments, the prompt information generated by the information output device is converted into a reminder SMS by the SMS sending module and sent to a preset recipient, thereby realizing remote prompt alarm.

[0020] In some embodiments, the positioning frame includes a rectangular second base plate, and at least two adjusting blocks are detachably connected to the four sides of the second base plate. The adjusting blocks protrude from the sides of the second base plate, and the width and length of the positioning frame can be adjusted by replacing different adjusting blocks.

[0021] In the above embodiments, the width and length of the positioning frame can be adjusted by replacing the adjusting block, eliminating the need to equip each housing with a dedicated positioning frame.

[0022] In some embodiments, the actuator includes a cylinder, a slider, a first guide seat, and a second guide seat. The piston rod of the cylinder is connected to the slider, the slider is slidably engaged with the second guide seat, the first guide seat has a guide hole, and the detection rod is slidably engaged with the guide hole and connected to the slider.

[0023] In the above embodiments, the slider and the first guide seat constitute a primary guide, and the second guide seat and the detection rod constitute a secondary guide. The detection rod can slide precisely in a preset direction, and the detection rod can be removed and replaced separately, making maintenance convenient.

[0024] In some embodiments, the metal casing is a mobile phone casing, a laptop casing, or a tablet casing.

[0025] In some embodiments, the top of the positioning frame is provided with a pressure cap that can be separated from the positioning frame.

[0026] In the above embodiments, the pressure cap can position the housing from the direction perpendicular to the second substrate, which can avoid false detection caused by the housing not being fully attached to the positioning frame.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] It eliminates the need for manual observation of the detection rod's condition and manual identification of the side hole's position, improving detection efficiency, avoiding observation errors, and thus increasing recognition accuracy.

[0042] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0043] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0044] The detection device of the present invention is used to detect whether the position accuracy of the side hole of the metal shell meets the standard.

[0045] Reference Figure 1 Metal housing 100 refers to a metal housing with one side open, and side hole 101 refers to a hole provided on the side of housing 100.

[0046] Combination Figures 1 to 8In some embodiments, the metal housing side hole position detection device includes a first substrate 2, and a positioning frame 1, a detection rod 3, an information output device, and a driver 8 disposed on the top surface of the first substrate 2. The positioning frame 1 can abut against the inner side wall of the housing 100. The detection rod 3 corresponds to the side hole 101 and can be inserted into and removed from the side hole 101 under the drive of the driver 7. The detection rod 3 includes a first end face 31 facing the side hole 101. The first end face 31 is provided with a first electrode 11 and a second electrode 12. The first electrode 11 and the second electrode 12 are both electrically connected to the information output device. When the position of the side hole 101 is not up to standard, the first end face 31 will abut against the housing 100 around the side hole 101 during the process of the detection rod 3 being driven to insert into the side hole 101. At this time, the first electrode 11 and the second electrode 12 are connected by the housing 100 to generate a trigger signal, triggering the information output device to output prompt information.

[0047] The positioning frame 1 is used to position the housing 100 and is fixed to the top surface of the first base plate 2. In use, the opening of the housing 100 faces downward and is placed on the positioning frame 1. The top of the positioning frame 1 provides support for the housing 100, and the four sides of the positioning frame 1 abut against the inner sidewall of the housing 100 to position the housing 100.

[0048] Positioning frame 1 can be specifically designed as a plate-like structure, such as... Figure 2 As shown.

[0049] The positioning frame 1 can also be designed as other structures, such as a frame structure.

[0050] Reference Figure 2 and Figure 3 Some preferred positioning frames 1 are as follows: The positioning frame 1 includes a second base plate 9 and several adjusting blocks 91. The second base plate 9 is rectangular, and each of its four sides is provided with at least two connecting grooves. The adjusting blocks 91 are provided with connecting rods, and the adjusting blocks 91 are detachably connected to the four sides of the second base plate 9 through the cooperation of the connecting rods and the connecting grooves. The adjusting blocks 91 protrude from the sides of the second base plate 9. The connecting grooves can be existing connecting grooves such as T-grooves or dovetail grooves, and the shape of the connecting rods is the same as the shape of the connecting grooves.

[0051] By using the aforementioned preferred positioning frame 1, when inspecting housings 100 of different specifications, it is not necessary to replace the entire positioning frame 1; only the adjusting block 91 needs to be replaced. This not only avoids positional deviations between the detection rod 3 and the positioning frame 1 caused by replacing the positioning frame 1, but also eliminates the need to equip each housing 100 with a dedicated positioning frame 1.

[0052] In some embodiments, the actuator 8 may be powered by a cylinder 7.

[0053] The driver 8 can also be powered by other existing power sources, such as linear motors.

[0054] In some embodiments, the actuator 8 includes a cylinder 7, a slider 6, a first guide seat 4, and a second guide seat 5. The first guide seat 4 and the second guide seat 5 are fixed to the top surface of the first substrate 2. The slider 6 is slidably engaged with the second guide seat 5. The first guide seat 4 is provided with a guide hole. The detection rod 3 is slidably engaged with the guide hole on the first guide seat 4. The detection rod 3 is connected to the slider 6. The slider 6 is connected to the piston rod of the cylinder 7.

[0055] Cylinder 7 drives slider 6 to move, and slider 6 drives detection rod 3 to move, thus achieving detection. During the process of piston rod changing from retracted state to extended state, it drives detection rod 3 to insert into side hole 101 of housing 100. During the process of piston rod changing from extended state to retracted state, it drives detection rod 3 to withdraw from side hole 101 of housing 100.

[0056] The size and shape of the upper hole 101 of different housings 100 may vary. To improve the adaptability of the detection device, the detection rod 3 is designed to be replaceable. In the above embodiment, the detection rod 3 is connected to the slider 6. When replacing the detection rod 3, it is not necessary to contact the cylinder 7. Moreover, the detection rod 3 is guided by the first guide seat 4, and the slider 6 is guided by the second guide seat 5. The output power of the cylinder 7 is transmitted to the detection rod 3 through the slider 6, which can ensure that the movement direction of the piston rod is consistent with the movement direction of the detection rod 3.

[0057] The detection rod 3 is used to detect whether the position of the side hole 101 of the housing 100 meets the standard. When the detection rod 3 can be smoothly inserted into the side hole 101 of the housing 100, the position of the side hole 101 of the housing 100 meets the standard. Otherwise, if the detection rod 3 cannot be inserted into the side hole 101 of the housing 100, the position of the side hole 101 of the housing 100 does not meet the standard.

[0058] In some embodiments, the number of detection rods 3 is the same as the number of side holes 101 in the housing 100. During detection, all detection rods 3 can be driven simultaneously to detect the position of all side holes 101 at the same time.

[0059] The number of detection rods 3 may also be less than the number of side holes 101 of housing 100. For example, some side holes 101 of housing 100 include multiple pickup holes arranged in a row. These pickup holes are stamped by the same mold, and the detection device may only configure detection rods 3 for two of the multiple pickup holes.

[0060] The detection rod 3 includes an insertion end and a power input end. The insertion end is used to insert into the side hole 101 of the housing 100, and the power input end is used to receive driving force from the driver 8. The insertion end should be adapted to the side hole 101 of the housing 100.

[0061] The detection rod 3 is preferably made of a non-conductive material, such as plastic or ceramic.

[0062] The first electrode 11 and the second electrode 12 are disposed at the insertion end of the detection rod 3, or more specifically, at the end face of the insertion end, that is, the first end face 31 of the detection rod 3 facing the side hole 101 of the housing 100.

[0063] The detection rod 3 is provided with a groove from the insertion end to the power input end, and a wire is provided in the groove. The wire connects the first electrode 11 and the second electrode 12 to the information output device on the first substrate 2.

[0064] The first electrode 11 and the second electrode 12 preferably have a ring structure. The first electrode 11 is a first ring extending along the circumference of the first end face 31 of the detection rod 3, and the second electrode 12 is a second ring concentric with the first ring. Figure 5 As shown. The first and second rings can be metal sheets, metal films, etc.

[0065] In the above scheme, two concentric rings are used to construct the first electrode 11 and the second electrode 12. When the side hole 101 of the housing 100 deviates upward, the upper semicircular arcs of the first and second rings can be abutted by the housing 100, connecting the first electrode 11 and the second electrode 12; when the side hole 101 of the housing 100 deviates downward, the lower semicircular arcs of the first and second rings can be abutted by the housing 100, connecting the first electrode 11 and the second electrode 12; when the side hole 101 of the housing 100 deviates downward, the lower semicircular arcs of the first and second rings can be abutted by the housing 100, connecting the first electrode 11 and the second electrode 12; when the side hole 101 of the housing 100 deviates downward... When 101 deviates to the left, the left semicircular arc of the first ring and the left semicircular arc of the second ring can be abutted by the housing 100, connecting the first electrode 11 and the second electrode 12; when the side hole 101 of the housing 100 deviates to the right, the right semicircular arc of the first ring and the right semicircular arc of the second ring can be abutted by the housing 100, connecting the first electrode 11 and the second electrode 12. That is, the first electrode 11 and the second electrode 12 can be connected regardless of the direction in which the side hole 101 of the housing 100 deviates, thus being effectively detected.

[0066] The first electrode 11 and the second electrode 12 can also be elastic needles. The elastic needles are fixed inside the detection rod 3, and the ends of the elastic needles protrude from the first end face 31 of the detection rod 3.

[0067] The first electrode 11 and the second electrode 12 can also be a dot-shaped metal film or a sheet-shaped metal film bonded to the first end face 31, such as Figure 6 As shown.

[0068] In some embodiments, the information output device includes an indicator light 10, which is positioned around the positioning frame 1. The indicator light 10, the detected side hole 101, and the detection rod 3 correspond to each other, such as... Figure 4 As shown. Indicator light 10, such as an LED or a tungsten filament lamp.

[0069] For example, a specific circuit of an information output device is as follows: (Refer to...) Figure 7 The positive terminal of indicator light 10 is electrically connected to the positive terminal of power supply 13, the negative terminal of indicator light 10 is electrically connected to the first electrode 11, and the negative terminal of power supply 13 is electrically connected to the second electrode 12.

[0070] When the detection rod 3 cannot be inserted into the side hole 101, the insertion end of the detection rod 3 abuts against the housing 100 surrounding the side hole 101. The first electrode 11 and the second electrode 12 on the detection rod 3 are connected by the housing 100. The indicator light 10, the first electrode 11, the second electrode 12, and the power supply 13 form a circuit, and the indicator light 10 illuminates, indicating that the position of the side hole 101 is not up to standard. When the detection rod 3 is successfully inserted into the side hole 101, the first electrode 11 and the second electrode 12 are not connected, the indicator light 10, the first electrode 11, the second electrode 12, and the power supply 13 do not form a circuit, and the indicator light 10 does not illuminate, indicating that the position of the side hole 101 is up to standard.

[0071] In the above scheme, indicator lights 10 are used to output prompt information. The position of indicator lights 10 corresponds to the side hole 101 being detected. The combination of the status and position of indicator lights 10 indicates that the side hole 101 is not in the correct position. This scheme has the advantages of simple structure and low cost.

[0072] When multiple side holes 101 are on the same side of the housing 100, the corresponding multiple indicator lights 10 are preferably indicator lights 10 with different light colors.

[0073] Reference Figure 8 In other embodiments, the information output device includes a location information generation module 14 and a prompt information generation module 15.

[0074] The position information generation module 14 is used to generate position information of the side hole 101 based on the number of the first electrode 11 or the number of the second electrode 12; the prompt information generation module 15 is used to generate a prompt information containing the position information when the first electrode 11 and the second electrode 12 are connected.

[0075] For example, a specific circuit of the information output device is as follows: the first electrode 11 and the second electrode 12 of all detection rods 3 are connected to the position information generation module 14, the output terminal of the position information generation module 14 is connected to the prompt information generation module 15, and the output terminal of the prompt information generation module 15 is connected to the voice playback module 16.

[0076] The numbers of the first electrode 11 and the second electrode 12 are both unique. Based on these numbers, any one of the detection rods 3 can be identified. Each detection rod 3 corresponds one-to-one with a side hole 101, thus allowing the location of the side hole 101 to be determined.

[0077] Assumptions: The side hole 101 corresponding to the power button is called the power hole, the side hole 101 corresponding to the volume control button is called the volume control hole, the corresponding detection rods are called the power hole detection rod and the volume control hole detection rod, the first electrode 11 on the power hole detection rod is numbered 1101, the second electrode 12 is numbered 1201, the first electrode 11 on the volume control hole detection rod is numbered 1102, and the second electrode 12 is numbered 1202.

[0078] When the position of the power port deviates, the power port detection rod abuts against the housing 100, and the first electrode 11, numbered 1101, and the second electrode 12, numbered 1201, are connected.

[0079] After the location information generation module 14 detects the connection signal, it obtains numbers 1101 and 1201, and generates the side hole location information "power hole" based on numbers 1101 and 1201.

[0080] After the prompt message generation module 15 detects the connection signal, it retrieves the prompt content "position accuracy not up to standard" and then generates a prompt message "power hole position accuracy not up to standard" containing the position information of the side hole 101 "power hole", which is then transmitted to the voice playback module 16.

[0081] After receiving the prompt message, the voice playback module 16 outputs the prompt voice "Power hole position is not up to standard".

[0082] In the above embodiments, the information output device automatically generates prompts based on the electrode number and status, eliminating the need for manual observation and identification of the location, resulting in a higher degree of automation and detection efficiency. Furthermore, since the prompts are converted into audio playback via the voice playback module 16, staff can promptly detect and receive alerts even when not physically present at the detection device.

[0083] Alternatively, the above-mentioned voice playback module 16 can be replaced by a short message sending module or an information display module.

[0084] Information display module, such as a display screen.

[0085] When using an SMS sending module, recipient information is preset, such as a mobile phone number or other personal communication terminal number. The SMS sending module generates an SMS message from the received notification information and sends it to the preset recipient, enabling remote notification and alarm functionality.

[0086] In some embodiments, the top of the positioning frame 1 is further provided with a pressure cap 17 (see... Figure 9When the housing 100 is placed with its opening facing down on the positioning frame 1, the pressure cap 17 is placed on the housing 100. The pressure cap 17 exerts pressure on the housing 100 in the direction perpendicular to the first substrate 2, positioning the housing 100 in this direction and ensuring that the housing 100 is in close contact with the top of the positioning frame 1. This can avoid false detection caused by the housing 100 not being fully in contact with the top of the positioning frame 1.

[0087] The working principle of the above-mentioned metal casing side hole position detection device is roughly as follows:

[0088] The housing 100 is placed on the positioning frame 1 with its opening facing downwards. The positioning frame 1 provides support for the housing 100. The four sides of the positioning frame 1 abut against the inner sidewall of the housing 100 to form a positioning. The cylinder 7 drives the detection rod 3 to insert the detection rod 3 into the corresponding side hole 101 of the housing 100. When the position of the side hole 101 meets the standard, the detection rod 3 can be smoothly inserted into the side hole 101. When the position of the side hole 101 does not meet the standard, the detection rod 3 cannot be inserted into the side hole 101, but abuts against the housing 100. The metallic properties of the housing 100 cause the first electrode 11 and the second electrode 12 on the detection rod 3 to be connected, thereby generating a trigger signal. The trigger signal causes the information output device to output a prompt message, thereby automatically identifying the non-compliant side hole 101.

[0089] The aforementioned metal casing side hole position detection device can automatically identify substandard side holes 101 without requiring manual observation of the detection rod 3 or manual identification of the side hole 101's position. This improves detection efficiency, avoids observation errors, and thus enhances identification accuracy. Furthermore, it eliminates the need for additional sensors to detect the side hole's position, resulting in a simple structure and low cost.

[0090] In particular, with the inclusion of a location information generation module 14 and a prompt information generation module 15 in the information output device, the level of automation is further improved, and the detection efficiency is further enhanced.

[0091] The aforementioned metal casing side hole position detection device is suitable for detecting the side hole position of metal casings, especially for mobile phone casings 100, laptop casings 100, and tablet casings 100. Mobile phone casings 100, laptop casings 100, and tablet casings 100 are characterized by a height much smaller than their length and width, and have multiple side holes 101 distributed on different sides of the casing, making top-down position detection unsuitable.

[0092] The present invention has been described in detail above through specific embodiments. These detailed descriptions are only intended to help those skilled in the art understand the content of the present invention and should not be construed as limiting the scope of protection of the present invention.
