[0032] Among them, the positioning frame 1 is used to position the shell 100, and the positioning frame 1 is fixed on the top surface of the first substrate 2. In use, the opening of the shell 100 faces downward and is placed on the positioning frame 1, the top of the positioning frame 1 forms a supporting action on the shell 100, and the four side portions of the positioning frame 1 abut against the inner side wall of the shell 100 to form positioning on the shell 100.

[0033] The positioning frame 1 can be designed as a plate structure, as Figure 2 shown.

[0034] The positioning frame 1 can also be designed as other structures, such as a frame structure.

The connecting grooves can be T-shaped grooves, dovetail grooves or other existing connecting grooves, and the connecting rods have the same shape as the connecting grooves.

[0036] When detecting different specifications of the shell 100, the above-mentioned preferable positioning frame 1 does not need to replace the entire positioning frame 1, but only needs to replace the adjusting blocks 91. Not only can the position deviation between the detection rod 3 and the positioning frame 1 caused by replacing the positioning frame 1 be avoided, but also it is not necessary to provide a special positioning frame 1 for each shell 100.

[0037] In some embodiments, the driver 8 can be powered by the air cylinder 7.

[0038] The driver 8 can also be powered by other existing power sources, such as linear motors and the like.

[0039] In some embodiments, the driver 8 comprises the air cylinder 7, the sliding block 6, the first guide seat 4 and the second guide seat 5, the first guide seat 4 and the second guide seat 5 are fixed on the top surface of the first base plate 2, the sliding block 6 is in sliding fit with the second guide seat 5, the first guide seat 4 is provided with a guide hole, the detection rod 3 is in sliding fit with the guide hole on the first guide seat 4, the detection rod 3 is connected with the sliding block 6, and the sliding block 6 is connected with the piston rod of the air cylinder 7.

[0040] The air cylinder 7 drives the sliding block 6 to move, the sliding block 6 drives the detection rod 3 to move, and detection is realized. In the process of the piston rod changing from the retracted state to the extended state, the detection rod 3 is driven to insert into the side hole 101 of the shell 100, and in the process of the piston rod changing from the extended state to the retracted state, the detection rod 3 is driven to exit from the side hole 101 of the shell 100.

[0041] The size and shape of the upper side hole 101 on different shells 100 can be different, in order to improve the adaptability of the detection device, the detection rod 3 is designed to be replaceable. In the above-mentioned embodiments, the detection rod 3 is connected to the sliding block 6, when the detection rod 3 is replaced, the air cylinder 7 does not need to be contacted, the detection rod 3 is guided by the first guide seat 4, the sliding block 6 is guided by the second guide seat 5, the output power of the air cylinder 7 is transmitted to the detection rod 3 through the sliding block 6, and it can be ensured that the movement direction of the piston rod is consistent with the movement direction of the detection rod 3.

[0042] The detection rod 3 is used to detect whether the position tolerance of the side hole 101 of the shell 100 is up to standard. When the detection rod 3 can be smoothly inserted into the side hole 101 of the shell 100, the position tolerance of the side hole 101 of the shell 100 is up to standard. Otherwise, if the detection rod 3 cannot be inserted into the side hole 101 of the shell 100, the position tolerance of the side hole 101 of the shell 100 is not up to standard.

[0043] In some embodiments, the number of the detection rods 3 is the same as the number of the side holes 101 of the shell 100. During detection, all the detection rods 3 can be driven at the same time, and the position tolerance of all the side holes 101 is detected at the same time.

[0044] The number of the detection rods 3 can also be less than the number of the side holes 101 of the shell 100. For example, some side holes 101 of the shell 100 include a plurality of pickup holes arranged in a row, and the plurality of pickup holes are punched by the same mold. The detection device can only be configured with detection rods 3 for two pickup holes in the plurality of pickup holes.

[0045] The detection rod 3 includes an insertion end and a power input end. The insertion end is used to be inserted into the side hole 101 of the shell 100, and the power input end is used to receive driving force from the driver 8. The insertion end should be matched with the side hole 101 of the shell 100.

[0046] The detection rod 3 is preferably made of non-conductive material, such as plastic, ceramic, etc.

[0047] The first electrode 11 and the second electrode 12 are arranged at the insertion end of the detection rod 3, more specifically, at the end face of the insertion end, i.e. the first end face 31 of the detection rod 3 facing the side hole 101 of the shell 100.

[0048] The detection rod 3 is provided with a wire slot from the insertion end to the power input end, and a wire is arranged in the wire slot. The wire electrically connects the first electrode 11 and the second electrode 12 with the information output device on the first substrate 2.

[0049] The first electrode 11 and the second electrode 12 are preferably in the form of a ring. The first electrode 11 is a first ring extending along the periphery 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, as shown in Figure 5 The first ring and the second ring can be a metal sheet, a metal film, etc.

[0050] In the above scheme, the first electrode 11 and the second electrode 12 are configured by two concentric rings, when the side hole 101 of the shell 100 is deviated upward, the upper semicircular arc of the first ring and the upper semicircular arc of the second ring can be abutted by the shell 100, connecting the first electrode 11 and the second electrode 12; when the side hole 101 of the shell 100 is deviated downward, the lower semicircular arc of the first ring and the lower semicircular arc of the second ring can be abutted by the shell 100, connecting the first electrode 11 and the second electrode 12; when the side hole 101 of the shell 100 is deviated leftward, the left semicircular arc of the first ring and the left semicircular arc of the second ring can be abutted by the shell 100, connecting the first electrode 11 and the second electrode 12; when the side hole 101 of the shell 100 is deviated rightward, the right semicircular arc of the first ring and the right semicircular arc of the second ring can be abutted by the shell 100, connecting the first electrode 11 and the second electrode 12, that is, the side hole 101 of the shell 100 is deviated in any direction, and the first electrode 11 and the second electrode 12 can be connected, so as to be effectively detected.

[0051] The first electrode 11 and the second electrode 12 can also be elastic needles, which are fixed in the detection rod 3, and the ends of the elastic needles are exposed from the first end surface 31 of the detection rod 3.

[0052] The first electrode 11 and the second electrode 12 can also be point-shaped metal films or sheet-shaped metal films combined with the first end surface 31, as shown in Figure 6 .

[0053] In some embodiments, the information output device includes an indicator light 10, the position of the indicator light 10 is located around the positioning frame 1, the indicator light 10, the detected side hole 101 and the detection rod 3 correspond, as shown in Figure 4 . The indicator light 10 is, for example, an LED or a tungsten lamp.

[0054] For example, a specific circuit of the information output device is as follows: referring to Figure 7 , the positive electrode of the indicator light 10 is electrically connected with the positive electrode of the power supply 13, the negative electrode of the indicator light 10 is electrically connected with the first electrode 11, and the negative electrode of the power supply 13 is electrically connected with the second electrode 12.

[0055] When the detection rod 3 cannot be inserted into the side hole 101, the insertion end of the detection rod 3 abuts against the shell 100 around the side hole 101, the first electrode 11 and the second electrode 12 on the detection rod 3 are connected by the shell 100, a loop is formed by the indicator light 10, the first electrode 11, the second electrode 12 and the power supply 13, the indicator light 10 emits light, indicating that the position degree of the side hole 101 is not up to standard. When the detection rod 3 is smoothly inserted into the side hole 101, the first electrode 11 and the second electrode 12 are not connected, a loop is not formed by the indicator light 10, the first electrode 11, the second electrode 12 and the power supply 13, the indicator light 10 does not emit light, indicating that the position degree of the side hole 101 is up to standard.

[0056] In the above scheme, the indicator light 10 outputs the prompt information, the position of the indicator light 10 corresponds to the side hole 101 to be detected, and the side hole 101 with an unqualified position is prompted by combining the state and position of the indicator light 10, which has the advantages of simple structure and low cost.

[0057] When multiple side holes 101 are on the same side of the shell 100, the corresponding multiple indicator lights 10 are preferably indicator lights 10 with different light-emitting colors.

[0058] Reference Figure 8 In other embodiments, the information output device includes a position information generation module 14 and a prompt information generation module 15.

[0059] The position information generation module 14 is configured 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; and the prompt information generation module 15 is configured to generate prompt information containing the position information when the first electrode 11 and the second electrode 12 are connected.

[0060] For example, a specific circuit of the information output device is as follows: the first electrode 11 and the second electrode 12 of all the detection rods 3 are connected to the position information generation module 14, the output end of the position information generation module 14 is connected to the prompt information generation module 15, and the output end of the prompt information generation module 15 is connected to the voice playing module 16.

[0061] The number of the first electrode 11 and the number of the second electrode 12 are both unique. According to the number, any detection rod 3 can be identified, and the detection rod 3 corresponds to the side hole 101 one-to-one, so the position of the side hole 101 can be identified.

[0062] Suppose: the side hole 101 corresponding to the power key is called the power hole, and the side hole 101 corresponding to the volume adjustment key is called the volume adjustment hole. The corresponding detection rods are called the power hole detection rod and the volume adjustment hole detection rod. The number of the first electrode 11 on the power hole detection rod is 1101, and the number of the second electrode 12 is 1201. The number of the first electrode 11 on the volume adjustment hole detection rod is 1102, and the number of the second electrode 12 is 1202.

[0063] When the position of the power hole deviates, the power hole detection rod abuts against the shell 100, and the first electrode 11 numbered 1101 and the second electrode 12 numbered 1201 are connected.

[0064] After the position information generation module 14 detects the connection signal, the numbers 1101 and 1201 are obtained, and the position information "power hole" of the side hole is generated according to the numbers 1101 and 1201.

[0065] When the detection signal is detected by the information output device, the prompt information "the position degree of the side hole 101 is not up to the standard" is generated and transmitted to the voice playing module 16.

[0066] When the prompt information is received by the voice playing module 16, the voice "the position degree of the side hole 101 is not up to the standard" is outputted.

[0067] In the above embodiment, the information output device automatically generates the prompt information in combination with the number and state of the electrode, without manual observation and identification of the position, so that the degree of automation is higher and the detection efficiency is higher. In addition, since the prompt information is converted into voice by the voice playing module 16, the staff can also discover the prompt alarm in time without being beside the detection device.

[0068] Alternatively, the voice playing module 16 can be replaced by a short message sending module or an information display module.

[0069] The information display module, for example, a display screen.

[0070] When the short message sending module is adopted, the receiver information, for example, the number of personal communication terminal such as mobile phone number, is preset. The short message sending module generates the received prompt information into a short message and sends it to the preset receiver, so that the remote prompt alarm can be realized.

[0071] In some other embodiments, the top of the positioning frame 1 is further provided with a pressing cover 17 (see Figure 9 When the shell 100 is placed with the opening downward on the positioning frame 1, the pressing cover 17 is placed on the shell 100, the pressing cover 17 generates the pressure on the shell 100 in the direction perpendicular to the first base plate 2, the shell 100 is positioned in this direction, so that the shell 100 is ensured to be attached to the top of the positioning frame 1, and the false detection caused by the incomplete attachment of the shell 100 to the top of the positioning frame 1 can be avoided.

[0072] The working principle of the above metal shell side hole position detection device is as follows: When the shell 100 is placed with the opening downward on the positioning frame 1, the positioning frame 1 forms the supporting effect on the shell 100, the four side portions of the positioning frame 1 abut against the inner side wall of the shell 100 to form the positioning, the cylinder 7 drives the detection rod 3 to make the detection rod 3 inserted into the corresponding side hole 101 of the shell 100, when the position degree of the side hole 101 is up to the standard, the detection rod 3 can be smoothly inserted into the side hole 101, when the position degree of the side hole 101 is not up to the standard, the detection rod 3 cannot be inserted into the side hole 101, but abuts against the shell 100, the metal property of the shell 100 makes the first electrode 11 and the second electrode 12 on the detection rod 3 be connected, so that the trigger signal is generated, the trigger signal makes the information output device output the prompt information, so that the side hole 101 not up to the standard is automatically identified.

[0073] The metal shell side hole position detection device can automatically identify the substandard side hole 101, does not need manual observation of the state of the detection rod 3, does not need manual identification of the position of the side hole 101, can improve the detection efficiency, can avoid observation errors, and thus improves the identification accuracy. Moreover, no additional sensor is needed to detect the position of the side hole, the structure is simple, and the cost is low.

[0074] Especially, after the information output device includes the position information generation module 14 and the prompt information generation module 15, the degree of automation is further improved, and the detection efficiency is further improved.

[0075] The metal shell side hole position detection device is suitable for side hole position detection of a metal shell, and is especially suitable for side hole position detection of a mobile phone shell 100, a notebook computer shell 100, and a tablet computer shell 100. The mobile phone shell 100, the notebook computer shell 100, and the tablet computer shell 100 have the characteristic that the height is much smaller than the length and the width, and have multiple side holes 101 distributed on different sides of the shell, which is not suitable for position detection from top to bottom.
