Specifically, when the electronic product is placed in the target installation position of the loading station, the installation position will be transferred to each preset detection station in turn through the rotating movement of the turntable. In this process, each detection equipment performs targeted detection operation on the electronic product in the target installation position according to its specific detection function and process requirement, such as appearance detection, performance parameter detection, size precision detection, etc., to ensure that each detection can be accurately performed on the corresponding installation position. To be able to match multiple detection requirements. The turntable as the core transmission component is designed to change the original linear production process into a circular or multi-station circulation process, thereby realizing the series connection of multiple detection processes in a limited floor area, extending the circulation path of the electronic product in a smaller space, effectively solving the problem of insufficient detection processes or too long detection path caused by space limitation in the traditional linear layout, and ensuring that different types of detection requirements can be met. The whole detection process does not involve sorting, and after the electronic product is transferred to the unloading station, the second carrying mechanism sorts according to the previous detection results, shortens the total process time, and can effectively improve the overall operation efficiency of the production line and the product quality control level. This post-sorting method avoids the process interruption and efficiency reduction caused by sorting during the detection process, while ensuring that all products go through a complete detection process, thereby significantly shortening the total process time of the whole production process, and effectively improving the overall operation efficiency of the production line and the product quality control level.

[0059] The present application provides a multi-performance testing device, please refer to Figures 3-4 The multi-performance testing device 100 comprises a machine table 1, a rotating disc 2, a plurality of detection devices and a conveying mechanism. The machine table 1 has a feeding station 1a, a plurality of detection stations 1b and a discharging station 1c arranged along the circumference thereof. The rotating disc 2 is rotatably installed on the machine table 1 along an axis extending in the up-down direction. The rotating disc 2 has a plurality of mounting positions 20, each of which is used for placing an electronic product to be detected. During the rotation of the rotating disc 2, each mounting position 20 can pass through the feeding station 1a, the plurality of detection stations 1b and the discharging station 1c. The plurality of detection devices are respectively located at the plurality of detection stations 1b. The conveying mechanism comprises a first conveying mechanism and a second conveying mechanism 9. The first conveying mechanism is used for transferring the electronic product to the feeding station and placing it in the corresponding mounting position. The second conveying mechanism 9 is used for removing the electronic product circulating to the discharging station.

[0060] In the technical solution of the present application, the plurality of detection devices are arranged in a circle and integrated on the machine table 1. The rotating disc 2 drives the electronic product to be detected to circulate between the plurality of stations. By reasonably designing the angle and the time of each rotation of the rotating disc 2, the detection of multiple performances can be realized in turn. The feeding station 1a is responsible for feeding the electronic product to be detected, and the discharging station 1c is responsible for discharging the electronic product after detection. The device is convenient to cooperate with the production line. The compact structure design and efficient detection process can quickly integrate into the existing production system, which has little effect on the production rhythm of the whole line, reduces the production interruption or waiting time caused by the separate design of the existing multiple detection devices, and can effectively improve the overall operation efficiency of the production line and the product quality control level.

[0061] Please refer to Figures 5-6 The plurality of detection devices can include resistance testing devices, capacitance testing devices, insulation testing devices, visual inspection devices 4, spring testing devices 5, etc. More or fewer detection devices can also be included, and the present application does not limit this.

[0062] In the present application, the first conveying mechanism and the second conveying mechanism 9 can be set as an automatic mechanical arm, or can be realized by a special positioning suction cup, a positioning clamping jaw cooperating with a multi-axis driving mechanism, and a visual detection mechanism can be arranged at the corresponding position of the first conveying mechanism platform, so as to ensure accurate product picking by visual guidance.

[0063] It should be noted that the feeding station 1a, the plurality of detection stations 1b and the discharging station 1c are arranged along the circumference, and the distance between each adjacent two stations can be the same or different, which can be reasonably designed according to the occupied space of each detection device. For example, taking the installation position 20 at the feeding station 1a as the zero point, the turntable 2 rotates 30° to the first detection station 1b, the electronic test device 3 works to detect the electronic product, after the detection is completed, the turntable 2 rotates 45° to the next detection station 1b, and the visual detection device 4 works to detect the product.

[0064] The present application does not limit the rotation direction of the turntable 2, and based on the arrangement of the production line and the arrangement direction of each device, the turntable 2 can always rotate clockwise to drive the electronic product to be detected, or the turntable 2 can always rotate counterclockwise to drive the electronic product to be detected.

[0065] In order to control the accurate stop of the turntable 2 when reaching each station, a program can be designed in advance, that is, a detection cycle is defined, the number of stop times of the turntable 2 accumulated in one rotation, the angle of each rotation, and the time of stay. A sensor or a physical stop structure can also be arranged, so as to control the stop of the turntable 2 after detecting that the turntable 2 reaches the specified position, and to rotate again after meeting the stay time or receiving the completion signal of the corresponding detection device.

[0066] Considering that the requirements of electronic products are different when different performance tests are performed, in some detection stations 1b, the position of the electronic product needs to be fixed to prevent the electronic product from moving during the detection process. In some embodiments, please refer to Figure 4, the turntable 2 has a middle region and a peripheral region arranged around the periphery of the middle region; the mounting position 20 is arranged in the peripheral region; the multi-performance testing device 100 further comprises a fixed disc 61 and at least one pressing member 62, the fixed disc 61 is fixedly installed on the machine table 1, the fixed disc 61 is arranged above the turntable 2 and corresponds to the middle region; the at least one pressing member 62 is located at one of the detection stations 1b, one end of the pressing member 62 is arranged on the fixed disc 61, and the other end extends to correspond to the peripheral region; the other end of the pressing member 62 can move in the up-down direction to press or release the electronic product. In the working process, the fixed disc 61 and the machine table 1 always remain fixed, the turntable 2 rotates relative to the fixed disc 61, the mounting position 20 is arranged in the peripheral region and is not blocked by the fixed disc 61, thereby ensuring the exposure state of the electronic product, and the pressing member 62 is installed based on the fixed disc 61, thereby keeping the position fixed. When the turntable 2 drives the electronic product to rotate to the specified station, the pressing member 62 moves to press and fix the product, thereby preventing the electronic product from moving during detection, and after detection is completed, the pressing member 62 is reset to release the electronic product, thereby enabling the turntable 2 to continue to rotate, avoiding obstruction and interference.

[0067] The driving mode and movement stroke of the pressing member 62 are not limited, in an embodiment, the movement of the pressing member 62 relies on the lever principle, a cylinder and a connecting rod are cooperated, the cylinder barrel of the cylinder is fixed on the fixed disc 61, the cylinder rod is connected with one end of the pressing member 62, and the connecting rod connects the cylinder barrel and the middle part of the pressing member 62, in the lifting process of the cylinder rod, the other end of the pressing member 62 can swing in an arc in the up-down direction, thereby realizing the pressing and releasing of the electronic product. In another embodiment, the whole pressing member 62 can be driven to lift in the up-down direction, the cylinder rod of the cylinder is fixedly connected with one end of the pressing member 62, so that in the lifting process of the whole pressing member 62, the other end of the cylinder can be lifted to realize the pressing and releasing of the electronic product.

[0068] In other embodiments, in order to adapt to the orientation of the electronic product, the pressing member 62 can also move in the horizontal direction. The movement can be realized by cooperation of a lifting mechanism and a linear driving mechanism.

[0069] The number of the pressing members 62 is not limited, and is designed according to the detection requirements of each detection device, for example, the pressing members 62 are arranged at the electronic detection device and the elastic force detection device, and the visual detection device 4 does not need to be designed with the pressing members 62, so as to avoid that the pressing members 62 block the surface of the electronic product and affect the effect of visual detection. Since the types of the detection devices corresponding to the detection stations 1b are different, when the pressing members 62 are arranged in multiple numbers, the sizes, shapes and extension directions of the multiple pressing members 62 can be arranged differently.

[0070] In order to ensure the positioning of the electronic product during the movement of the turntable 2, the multi-performance testing device 100 further comprises a positioning tool 21 arranged at the mounting position 20, the positioning tool 21 being provided with a mounting groove which is shaped according to the electronic product, so as to limit the horizontal position of the electronic product. It should be noted that, when the space permits, a positioning structure can be additionally arranged on the positioning tool 21 to press and fix the electronic product.

[0071] In this embodiment, the positioning tool 21 is fixed relative to the turntable 2 to preliminarily position the electronic product, the pressing member 62 cooperates with the fixing disc 61 to further fix the electronic product when the electronic product reaches the designated position, so as to ensure the detection accuracy of each detection link.

[0072] Specifically, please refer to Figure 6 The visual detection device 4 comprises a support 41, a first movable seat 42, a camera 45, a coaxial light source 43 and a planar light source 44, the support 41 being fixed to the machine table 1; the first movable seat 42 is movably arranged on the support 41 in the up-down direction and in the horizontal direction, and the first movable seat 42 is provided with the camera 45 and the coaxial light source 43; the planar light source 44 is fixed to the support 41. The lifting of the first movable seat 42 can cooperate with the focusing of the camera 45, and the coaxial light source 43 can move with the camera 45, so as to adapt to the shooting requirements of the camera 45 at different positions. The planar light source adopts side light combined with a diffusion plate to form a large-area, soft and uniform diffuse light, which directly irradiates the surface of the object from the front, is suitable for large field of view and high uniformity requirement scenes, and can avoid local overexposure. The coaxial light passes through a half-transmission half-reflection beam splitter to make the light parallel to the lens optical axis of the camera 45, and vertically irradiate the object, which is good at detecting small defects on smooth surfaces, overcoming the interference of reflection, and the imaging edge is sharp. Based on the different characteristics of the coaxial light and the planar light irradiated on the surface of the object, one of the planar light source 44 and the coaxial light source 43 can be reasonably selected to work in the visual detection link according to the detection requirements of the electronic product. For example, the planar light is used for irradiation when the size of the electronic product is measured, the profile is positioned or the overall appearance of the surface of the object is observed; the coaxial light can provide higher contrast when the electronic product is detected for small defects such as scratches, cracks and depressions, or the characters on the high-reflectivity surface are read.

[0073] It should be noted that, at different positions and different focal lengths of the camera 45, different light irradiation can be used to control the camera 45 to take multiple shots.

[0074] In some embodiments, the main purpose of the elastic force test is to test the elastic force change curve when the key is pressed and rebounded. Please refer to Figure 7The elastic test device 5 comprises a base 51, two sliding seats 52 and two detection pieces 53. The base 51 is fixed to the machine table 1. Each sliding seat 52 is movably installed on the base 51 in the horizontal direction. Each sliding seat 52 is provided with a detection piece 53. The two detection pieces 53 are used to press two keys of the electronic product. The detection piece 53 can be a pressure sensor or a pressing test probe. The straight lines where the movement tracks of the two sliding seats 52 are located are intersected. For the keys on the side of the electronic product, the angle between the two sliding seats 52 can be set to avoid collision and interference of the two detection pieces 53 during operation. The two sliding seats 52 can be driven by two obliquely placed electric push cylinders. The detection piece 53 is connected with a control device to convert the detected data into a curve graph. The linear driving of the base 51 can be realized by the cooperation of the guide rail and the cylinder.

[0075] Please refer to Figure 5 The electronic test device 3 comprises a mounting seat 31, a second movable seat 32 and a plurality of test probes. The second movable seat 32 is movably installed on the mounting seat 31 in the up-down direction. The plurality of test probes are arranged on the second movable seat 32 in a spaced manner. The plurality of test probes comprise a capacitance test probe 33, a resistance test probe 34, an insulation test probe 35 and an auxiliary probe 36. The auxiliary probe 36 can cooperate with the capacitance test probe 33 or the insulation test probe 35 to form a conduction circuit by contacting the electronic product. The capacitance test probe 33, the resistance test probe 34 and the insulation test probe 35 are all installed by floating structures to have floating strokes in the up-down direction or in the horizontal direction. The integration of the plurality of test probes on one device is realized by the spaced arrangement and movement cooperation of the plurality of test probes. The plurality of test probes can be synchronously lifted under the driving of the second movable seat 32. The capacitance test probe 33 can be in contact with the corresponding test position of the electronic product to perform the test. The insulation test and the resistance test are performed separately. The auxiliary probe 36 serves as a current outlet to form a conduction circuit with the resistance test probe 34 during the resistance test and to form a conduction circuit with the insulation test probe 35 during the insulation test.

[0076] The specific form of the floating structure is not limited and can be the cooperation of springs, equal-height bolts, seat plates and other related structures. In some embodiments, the resistance test probe 34 and the capacitance test probe 33 both have floating strokes in the up-down direction. The insulation test probe 35 has a floating stroke in the horizontal direction. In other embodiments, the floating directions of the three test probes having test functions can also be the same, for example, both in the up-down direction or both in the horizontal direction.

[0077] It should be noted that each probe forms an independent circuit through line cooperation. Therefore, even if multiple probes are in contact with the electronic product, only one of the multiple probes needs to be controlled to be connected to electricity to ensure that each test does not affect each other.

[0078] Considering that the probe needs to be in contact with the surface of the electronic product when cooperating with the electronic product, the avoidance hole can be arranged on the turntable 2, and the bottom wall of the installation groove is partially hollowed out when the positioning tool 21 is arranged. The installation groove is used for installing the electronic product. The plurality of test probes are in contact with the electronic product through the hollowed-out position. The electronic contact detection requirement can be met, and the overall mechanism can be lightened to reduce the burden of the driving mechanism of the turntable 2.

[0079] The electronic test equipment 3 further comprises a boss and a slide table. The boss is arranged on the second movable seat 32. The slide table is located at the side of the boss and is movably arranged on the second movable seat 32 in the horizontal direction. The auxiliary probe 36 is arranged on the side of the slide table facing the boss and is higher than the boss. The capacitance test probe 33 and the insulation test probe 35 are arranged on the boss in the circumferential direction of the boss. The capacitance test probe 33 and the insulation test probe 35 extend upward, and the heights of the capacitance test probe 33 and the insulation test probe 35 are different. The resistance test probe 34 is arranged on the boss. Specifically, the insulation test probe 35, the capacitance test probe 33 and the resistance test probe 34 can be synchronously moved under the driving of the second movable seat 32. At the same time, based on the arrangement of the boss and the slide table, the auxiliary probe 36 extends in the horizontal direction and can be translated under the action of the slide table. The resistance test probe 34 can move in the horizontal direction by relying on the horizontal arrangement of the cylinder and the supporting table to provide a side driving force. The capacitance test probe 33 and the insulation test probe 35 extend in the upward and downward directions. Based on the height difference between the two, the different detection positions of the electronic product can be adapted. At the same time, due to the floating installation of the related probes, the detection position difference of the electronic product with different shapes can be adapted.

[0080] Specifically, the insulation test probe 35, the capacitance test probe 33 and the resistance test probe 34 are arranged in the circumferential direction, and the insulation test probe 35 is arranged close to the auxiliary probe 36. The second movable seat 32 realizes the lifting action by cooperating with the slide rail and the driving mechanism. The slide table realizes the translation by the cylinder driving. The driving mechanism can be a cylinder, a lead screw or the like.

[0081] It should be noted that a plurality of capacitance test probes 33 can be arranged in the circumferential direction of the boss, corresponding to different test positions of the electronic product. For electronic products with different shapes and specifications, part of the capacitance test probes 33 can also be in contact with the detection parts of the electronic product to realize circuit conduction.

[0082] In order to ensure that the electronic testing device 3 can be compatible with different detection positions of the resistance testing probe 34 and the insulation testing probe 35, the middle part of the boss is provided with a protruding column, and the side surface of the protruding column is provided with a mounting hole; one end of the resistance testing probe 34 is movably mounted in the mounting hole and is driven to move along the extension direction of the mounting hole through the side pushing force structure, and the other end is exposed outside the mounting hole and is used for contacting the electronic product. That is, the resistance testing probe 34 has a certain displacement, so as to be adjusted to different positions.

[0083] Further, the mounting position 20 is used for arranging two electronic products side by side, when the mounting position 20 of the turntable 2 is provided with the positioning tool 21, correspondingly, the positioning tool 21 is provided with two arranging grooves for arranging two electronic products. The electronic testing device 3 is provided with two, and the two electronic testing devices 3 are arranged at intervals along the circumference of the turntable 2; the elastic force testing device 5 is provided with two, and the two elastic force testing devices 5 are arranged at intervals along the circumference of the turntable 2. In the process of rotating the turntable 2, the two electronic testing devices 3 are passed in turn, each electronic testing device 3 corresponds to one electronic product, and the related parameters of the electronic product are detected, so as to match the lifting test requirement of the electronic device, and be beneficial to the control of the production rhythm, and balance the waiting time of the turntable 2 after each stop as much as possible. In the process of rotating the turntable 2, the two elastic force testing devices 5 are passed in turn, each electronic testing device 3 corresponds to one electronic product, and the two side keys of the electronic product are contacted, so as to avoid the detection space limitation existing in the two products arranged side by side.

[0084] Based on the above embodiment, two pressing pieces 62 can be arranged corresponding to the two electronic testing devices 3, and the corresponding relationship between the two pressing pieces 62 and the positioning tool 21 is different, the two arranging grooves of the positioning tool 21 are respectively a first arranging groove and a second arranging groove, when the turntable 2 stops at the corresponding position, one of the two pressing pieces 62 corresponds to the first arranging groove, and the other pressing piece corresponds to the second arranging groove,

[0085] In some embodiments, the pressing piece 62 can also simultaneously position and press two electronic products.

[0086] Similarly, two pressing pieces 62 can also be arranged corresponding to the two elastic force testing devices 5.

[0087] The turntable 2 is provided with an optical fiber 22, and the optical fiber 22 is located at the mounting position 20, so as to realize real-time detection of the mounting of the electronic product to be detected.

[0088] A plurality of mounting positions 20 are arranged along the circumferential direction of the turntable 2, and the number of the plurality of mounting positions 20 matches the number of the plurality of workstations, so that the electronic product loading in the loading workstation 1a can be synchronized with the detection work in the detection workstation 1b, thereby improving the efficiency.

[0089] The accuracy of the turntable 2 affects the alignment of the detection station 1b. In some embodiments, the machine 1 also has a zero-point calibration station 1d, and the turntable 2 passes through the zero-point calibration station 1d during rotation. The multi-performance testing device 100 includes a calibration structure (not shown in the figure), which includes a sensor and an identification piece. The sensor is arranged at the zero-point calibration station 1d, and the identification piece is arranged on the turntable 2 and can be identified by the sensor. During rotation of the turntable 2, based on the arrangement position of the mounting position 20 and the identification piece, when the turntable 2 drives the mounting position 20 to rotate to one of the stations, the identification piece should be at the zero-point calibration station 1d, so as to be identified by the sensor. When the rotation accuracy of the turntable 2 deviates, the sensor will identify the identification piece at the same rotation angle, or the sensor will not be able to identify the identification piece, so as to determine the rotation accuracy problem of the turntable 2. The turntable 2 can be calibrated, and the rotation angle of the turntable 2 can be adjusted or compensated in time, so as to ensure the machining accuracy.

[0090] In the present embodiment, there is one feeding station, one discharging station, one zero-point calibration station, two electronic testing detection stations, one visual detection station, and two elastic force testing detection stations, a total of eight stations. Correspondingly, eight mounting positions 20 are arranged on the turntable 2, one-to-one corresponding to the eight stations, and the identification piece is arranged at the corresponding mounting position 20. In this way, the station where the identification piece is arranged does not participate in the placement and detection of the electronic product, but is only used for calibration. That is, the number of mounting positions 20 matches the total number of stations on the machine 1, and the mounting position 20 corresponding to the zero-point calibration station 1d is an idle mounting position.

[0091] In this way, zero-point calibration can be performed when the device is idle, or it can be performed while other detection devices are working normally. The execution of the zero-point calibration program will not affect the normal detection rhythm and will not increase the waiting time. It is also not necessary to interrupt the detection process.

[0092] Since the electronic products reach the unloading station 1c after all the detection items are completed, the intermediate link does not sort the electronic products, and therefore, at the unloading station 1c, the electronic products have various detection results, specifically: all-pass detection qualified, all-pass detection unqualified, one-way detection unqualified, and two-way detection unqualified. The processing results of different detection items of the electronic products are different, for example, if it is a size problem, it cannot be remedied and can only be scrapped, and if it is an elastic test anomaly, it can be repaired by replacing the key. In view of this, the multi-performance test equipment 100 further comprises a plurality of sorting tables 7, a reader 8, and a control device, the plurality of sorting tables 7 are located at the side of the turntable 2 and are arranged close to the unloading station 1c; the plurality of sorting tables 7 correspond to different detection results of the electronic products, for example, a repair sorting table, a qualified product sorting table, and a scrap sorting table. For example: a qualified product sorting table, an electronic test anomaly sorting table, and an elastic test anomaly sorting table. The reader 8 is arranged at the unloading station 1c and is used to identify the identification code of the electronic product and can read the identification information of the identification code; the control device is electrically connected with the reader 8 and the second conveying mechanism 9. The electronic product is associated with the identification code of the electronic product at the beginning of detection, each electronic product has a specific identification code, and the detection result is recorded in the identification information of the corresponding electronic product after the detection result is uploaded to the cloud by each detection device; the active stroke of the second conveying mechanism 9 passes through the reader 8 and the plurality of sorting tables 7; the control device can confirm the detection result of the electronic product picked up by the second conveying mechanism 9 according to the identification information read by the reader 8, and then control the second conveying mechanism 9 to transfer the electronic product flowing to the unloading station 1c to the corresponding sorting table 7 based on the sorting logic of the sorting table 7. Thus, the unloading station 1c is divided and sorted based on the NG of the electronic product.

[0093] The control device can be an industrial computer, including a processing device (such as a central processing unit, a graphics processing unit, etc.), which can perform various appropriate actions and processes according to programs stored in a read-only memory (ROM) or loaded from a storage device to a random access memory (RAM). In the RAM, various programs and data required for the operation of the control device are also stored. The processing device, the ROM, and the RAM are connected to each other through a bus. An input / output (I / O) interface is also connected to the bus. Generally, the following systems can be connected to the I / O interface: input devices including, for example, a touch screen, a touchpad, a keyboard, a mouse, an image sensor, a microphone, an accelerometer, a gyroscope, etc.; output devices including, for example, a liquid crystal display (LCD), a speaker, a vibrator, etc.; storage devices including, for example, a magnetic tape, a hard disk, etc.; and communication devices. The communication device can allow the control device to communicate with other devices wirelessly or by wire to exchange data.

[0094] The application provides a control method of a multi-performance testing device.

[0095] Please refer to Figures 1-2 The control method of the multi-performance testing device comprises the following steps:

[0096] Step S10, after recognizing that the target installation site 20 has an electronic product, entering a detection mode;

[0097] It should be noted that when the rotating disc 2 rotates to drive one of the installation sites 20 to be at the feeding station 1a, the installation site 20 is taken as the target installation site 20.

[0098] The rotating disc 2 is provided with a plurality of installation sites 20, and when each installation site 20 is empty and at the feeding station 1a, the installation site 20 is taken as a new target installation site 20, after the electronic product is placed, the rotating disc 2 rotates to drive the electronic product to pass through the plurality of detection devices in the detection mode.

[0099] Therefore, in the actual production line, with the rotation of the rotating disc 2, the electronic product in the target installation site 20 is continuously taken away after the detection is completed, so that the target installation site 20 is empty and changes into a common installation site 20, and a new target installation site 20 is also formed.

[0100] Step S20, in the detection mode, the rotating disc 2 is controlled to rotate, and the electronic product at the target installation site 20 is driven to pass through the plurality of detection stations 1b in turn, so as to correspondingly obtain a plurality of test data, and according to the test data, the detection result of the electronic product at the target installation site 20 at each detection device is confirmed.

[0101] It should be noted that the plurality of test data comprises a capacitance value, an insulation resistance value, a resistance value, an elastic force test curve, a size detection value and an appearance detection graph. There is a case that one detection device can obtain a plurality of test data at the same time. For example, the visual detection device 4 can obtain the size detection value and the appearance detection graph after taking a photo. An electronic test device 3 can be designed to integrate capacitance test, resistance test and insulation test.

[0102] In the plurality of detection stations 1b, the detection devices corresponding to each detection station 1b can all be different, or the detection devices corresponding to some detection stations 1b can be the same. This is mainly to adapt to the case that the installation site 20 simultaneously places a plurality of electronic products.

[0103] According to different detection requirements of different electronic products, the rotating disc 2 can be controlled to stay at only some detection stations 1b when the detection mode is executed according to the current detection requirement.

[0104] Step S30, after the target mounting position 20 is transferred to the unloading station 1c, the second carrying mechanism 9 is controlled according to the plurality of detection results to sort the electronic products.

[0105] In the technical scheme of the present application, when each vacant mounting position 20 is transferred to the loading station 1a as a target mounting position 20, after the electronic product is placed, the detection equipment based on the loading of the target mounting position 20 performs a detection mode in the process requirement. Specifically, when the electronic product is placed in the target mounting position 20 of the loading station 1a, the mounting position 20 will be transferred to each preset detection station 1b in turn through the rotating motion of the turntable 2. In this process, each detection equipment performs targeted detection operation on the electronic product in the target mounting position 20 according to its specific detection function and process requirement, such as appearance detection, performance parameter detection, size precision detection, etc., to ensure that each detection can be accurately performed on the corresponding mounting position 20. To be able to match multiple detection requirements. The turntable 2 as the core transmission component is designed to change the original linear production process into a circular or multi-station circulation process, thereby realizing the series connection of multiple detection processes in a limited floor area, extending the circulation path of the electronic product in a smaller space, effectively solving the problem of insufficient detection processes or too long detection path caused by space limitation in the traditional linear layout, and ensuring that different types of detection requirements can be met. The whole detection process does not involve sorting, and after the electronic product is transferred to the unloading station 1c, the second carrying mechanism 9 sorts according to the previous detection results, shortens the total process time, and can effectively improve the overall operation efficiency of the production line and the product quality control level. This post-sorting method avoids process interruption and efficiency reduction caused by sorting during detection, while ensuring that all products go through a complete detection process, thereby significantly shortening the total length of the entire production process while ensuring product quality, thereby effectively improving the overall operation efficiency of the production line and the product quality control level.

[0106] Further, step S20 includes:

[0107] Step S21, control the turntable 2 to stop after rotating to a preset angle in the counterclockwise direction, at this time the target mounting position 20 reaches the corresponding detection station 1b;

[0108] For example, taking the target mounting position 20 in the loading station 1a as the zero position, the target mounting position 20 is rotated from the loading station 1a to the first detection station 1b, and the turntable 2 is rotated by 30°.

[0109] Step S22, after obtaining the test completion signal of the corresponding detection equipment, obtaining the test data and detection results of the electronic product detected by the detection equipment;

[0110] It should be noted that the residence time of the turntable 2 in each detection station 1b is uncertain, and the actual time taken by the detection equipment of the current detection station 1b to complete detection is used as the reference.

[0111] For example, after the electronic test equipment 3 completes the test of resistance, capacitance and insulation resistance, the test data and the analysis result are uploaded, the electronic test equipment 3 sends a signal of completion of detection to the control device, the control device can directly obtain the corresponding test data and detection result from the cloud, and at the same time, the control device controls the turntable 2 to end the stop and continue to rotate.

[0112] In step S23, the turntable 2 continues to rotate until the target mounting position 20 passes through all the detection stations 1b and reaches the unloading station 1c, and the multi-performance test of the electronic product is completed.

[0113] It should be noted that the rotation angle of the turntable 2 driving the target mounting position 20 to rotate to each detection station 1b can be the same or different, and the residence time at each station can be the same or different.

[0114] For example, there are 6 detection stations 1b, and the electronic product needs to be detected in the 6 detection stations 1b according to the process requirement. At this time, the target mounting position 20 needs to stop at each detection station 1b, and after passing through the last detection station 1b, all detection items are completed, and the target mounting position 20 reaches the unloading station 1c, at which time the multi-performance test of the electronic product is completed.

[0115] For example, there are 6 detection stations 1b, and the electronic product needs to be detected in 3 detection stations 1b according to the process requirement. At this time, the target mounting position 20 needs to stop at the corresponding 3 detection stations 1b, and other detection stations 1b can be directly skipped. After passing through the third detection station 1b in the counterclockwise direction, all detection items can be completed, and the target mounting position 20 is directly transferred to the unloading station 1c, at which time the multi-performance test of the electronic product is completed.

[0116] Further, step S20 includes uploading the plurality of detection results to the cloud and associating the detection results with the identification code of the electronic product;

[0117] The electronic product is identified by its identification code at the beginning of entering the production line, and each electronic product has a specific identification code, which can be a two-dimensional code or a bar code. After the detection result is uploaded to the cloud, the identification code of the electronic product is associated, so that when the identification code is read again, the test data of the electronic product can be obtained, which is beneficial to the centralized sorting of the electronic product after completing the multi-detection.

[0118] Based on the above embodiment, step 30 includes:

[0119] Step 31, control the second conveying mechanism 9 to pick up the electronic product located at the unloading station 1c and move the electronic product to the reader 8;

[0120] That is, after the second conveying mechanism 9 picks up the electronic product from the unloading station 1c, the electronic product is first moved to the reader 8 for detection result confirmation of the electronic product.

[0121] It should be noted that the identification code of the electronic product is identified by the second conveying mechanism 9 because the identification code is easily blocked after the electronic product is placed on the positioning tool 21 of the mounting position 20. At this time, even if the reader 8 is provided at the unloading station 1c, the identification code cannot be identified because it is not fully displayed. The specific pickup and reading link of the second conveying mechanism 9 can be compatible with all electronic products. For different label positions of different electronic products, only the control program needs to be set to rotate the electronic product by a specific angle to display the identification code at the camera of the reader 8.

[0122] Step 32, according to the identification information read by the reader 8, determine the abnormal state type of the electronic product.

[0123] It should be noted that the division logic of the abnormal state type of the electronic product can be: no abnormality, single detection abnormality, double detection abnormality, and full detection abnormality. The division logic of the electronic abnormal state type can also include no abnormality, capacitance detection abnormality, resistance detection abnormality, insulation detection abnormality, appearance detection abnormality, size detection abnormality, and elasticity detection abnormality. The present application does not limit this.

[0124] Step 33, according to the abnormal state type, control the second conveying mechanism 9 to place the electronic product on the corresponding sorting table 7.

[0125] The number of sorting tables 7 matches the abnormal state type, and trays can be provided on the sorting tables 7 to accommodate the electronic products, which facilitates the centralized processing of the sorted electronic products. This post-sorting method avoids process interruption and efficiency reduction caused by sorting during detection. Data is synchronized by the identification code, and the program of the second conveying mechanism 9 is simple and easy to implement. Further, the overall operation efficiency of the production line is effectively improved.

[0126] Further, in step S20:

[0127] Step S21A, the electronic product at the target mounting position 20 is brought to the vision detection device 4;

[0128] It should be noted that the vision detection device 4 detects the appearance and size of the product, so different photographs are needed for different detection items.

[0129] Step S22A, based on the synchronization control algorithm of the light source and the camera trigger time, controls one of the coaxial light source 43 and the planar light source 44 to work, or controls the coaxial light source 43 and the planar light source 44 to work in sequence.

[0130] It should be noted that the light source is added to light the surface of the electronic product, thereby improving the shooting effect of the camera. The opening time of the light source and the shooting time of the camera should be synchronized, for example, the planar light source 44 is turned on for 15s, and the camera is simultaneously shot and the exposure time is 15s.

[0131] It should be noted that when the size of the electronic product is measured, the contour is positioned, or the overall appearance of the object surface is observed, the planar light is used for irradiation; when the electronic product is detected for scratches, cracks, depressions and other small defects, or the engraved characters on the high-reflectivity surface are read, the coaxial light can provide higher contrast. Therefore, according to the detection needs, one of the coaxial light source 43 and the planar light source 44 is controlled to work with the camera.

[0132] Since the shooting focal length and light source requirements of appearance detection and size detection are different, corresponding to different detection needs of different electronic products, the coaxial light source 43 and the planar light source 44 are opened multiple times to cooperate with the camera multiple times to shoot at this station.

[0133] For example, the planar light source 44 is first opened with the camera to cooperate, the exposure time is 15s, then the coaxial light source 43 is opened with the camera to cooperate, the exposure time is 10s; then, the coaxial light source 43 is opened with the camera to cooperate again, the exposure time is 10s, and the detection is completed.

[0134] For example, the coaxial light source 43 is opened with the camera to cooperate, the exposure time is 20s, and the detection is completed.

[0135] In step S20, based on the elastic test equipment 5, an adaptive test sequence is adopted, that is, the active stroke of the slide 52 during the detection of subsequent products is dynamically adjusted through the detection result of the first product.

[0136] Step S10 includes:

[0137] Step S11, controlling the first conveying mechanism to pick up the electronic product;

[0138] It should be noted that the first conveying mechanism can be directly arranged on the machine table 1, the first conveying mechanism can also be arranged in the front work station, and the active stroke can meet the spacing between the discharging of the last work station and the feeding of the present work station. The first conveying mechanism can also be arranged on the ground.

[0139] Step S12, obtaining first position information of the electronic product on the first conveying mechanism;

[0140] It should be noted that the visual detection device can be arranged on the machine 1, or arranged on the pickup gripper of the first conveying mechanism. After the electronic product is picked up by the first conveying mechanism, the accurate positioning matching relationship between the two should be ensured, so as to ensure the accuracy of the position of the electronic product when it is placed.

[0141] Step S13, when the first position information meets the first preset condition, the first conveying mechanism is controlled to place the electronic product on the target mounting position 20.

[0142] For example, through visual guidance, the positioning accuracy requirement of the first position information is ±0.02mm. If the deviation value of the current position coordinate and the set position coordinate meets the requirement of ±0.02mm, it is determined that the first position information meets the first preset condition, and at this time the first conveying mechanism can drive the electronic product to transfer. If the deviation value of the current position coordinate and the set position coordinate does not meet the requirement of ±0.02mm, the electronic product needs to be placed back, and then picked up after adjusting the positioning.

[0143] Step S14, obtaining second position information of the electronic product on the target mounting position 20.

[0144] It should be noted that the position sensor and light detection can be used to detect the position of the electronic product on the turntable 2.

[0145] Step S15, when the second position information meets the second preset condition, entering the detection mode.

[0146] For example, through the light example, the presence or absence and position of the electronic product are detected.

[0147] The deviation value of the current position coordinate and the set position coordinate meets the requirement of ±0.05mm, it is determined that the second position information meets the second preset condition, and at this time the first conveying mechanism can be reset, the turntable 2 can continue to rotate, and the corresponding detection equipment enters the detection mode. If the deviation value of the current position coordinate and the set position coordinate does not meet the requirement of ±0.05mm, the electronic product needs to be taken away again, and then placed again after adjusting the positioning.

[0148] Through the cooperation of pickup accuracy limitation and placement accuracy limitation, accurate positioning in the electronic product feeding process is realized, the installation accuracy of the electronic product is ensured, and the corresponding condition of the electronic product after circulation and the detection equipment is ensured.

[0149] Further, after step S20, it further includes:

[0150] The test data corresponding to the qualified detection result is stored, and the historical test data is associated to generate a data model.

[0151] It should be noted that the test data of each detection device is collected as the accumulation of the device data large model. According to the historical data, a learning model can be built, so that the product review and new product development reference of the designer are facilitated.

[0152] In addition to the above steps, the control method of the multi-performance test device further includes the following steps:

[0153] Step S40, when the multi-performance test device meets the preset working condition, triggering the zero point calibration mode;

[0154] It should be noted that the zero point calibration mode is triggered after the multi-performance test device accumulatively completes n workpiece detections; the design logic of n is not limited, for example, the specific number of n can be set according to batches, assuming that the electronic product of each batch is 200, then the value of n is an integer multiple of 200, so as to match the idle time of the device. The design logic of n can also not consider the production batch, and be designed according to the self condition of the driving device, for example, when the device is new, the value of n can be 1k, and when the device reaches a certain use time, the value of n can be adjusted to 500.

[0155] Alternatively, when the cumulative work of the multi-performance test device reaches the preset length of time, the zero point calibration mode is triggered.

[0156] It should be noted that the zero point calibration mode is independent of the detection mode, and the two modes are independently operated and have different reference objects and triggering rules. That is, the zero point calibration mode can be triggered in the non-detection mode, or the zero point calibration mode can be triggered in the detection mode.

[0157] In some embodiments:

[0158] In the zero point calibration mode:

[0159] Step S50A, controlling the rotation of the turntable 2, and calculating the interval time t and the rotation angle difference θ of the turntable 2 after the sensor continuously recognizes the recognition piece twice;

[0160] It should be noted that the setting position of the recognition piece is not limited at this time, and can be set at the installation position 20, or can be set at any position of the turntable 2, which is spaced from the installation position 20.

[0161] Step S60A, when t and θ meet the preset threshold, controlling the multi-performance test device to continue working.

[0162] Step S70A, when t and / or θ does not meet the preset threshold, calculating the difference value of t and / or θ;

[0163] It should be noted that, at a certain interval t, the set rotation angle of turntable 2 is 360°. Ideally, after the sensor first detects the identification object, turntable 2 rotates 360° before the sensor detects the identification object a second time. However, based on the reaction mechanism of the drive mechanism, a certain error range is allowed. Therefore, when t and / or θ do not meet the preset threshold, that is, when the actual rotation angle of the turntable is less than 360° or exceeds 360°, it indicates that the rotation of turntable 2 has deviated.

[0164] Step S80A: Compensate the working parameters of the turntable 2 drive mechanism based on the difference value.

[0165] Specifically, the difference needs to be converted into the working parameters of the drive mechanism, such as the technical speed and power.

[0166] This ensures the accuracy of subsequent operations of turntable 2 after zero-point calibration through a compensation algorithm.

[0167] In another embodiment, the station for setting the identification component does not participate in the placement and testing of electronic products, but is only used for calibration. The number of installation positions 20 matches the total number of stations on the machine tool 1. Among the multiple installation positions 20, the installation position 20 corresponding to the zero-point calibration station 1d is an idle installation position 20, and the identification component is set in the idle installation position 20. Along the clockwise direction, the detection station 1b located behind the zero-point calibration station 1d is the target detection station 1b.

[0168] In zero-point calibration mode:

[0169] Step S50B: Control turntable 2 to rotate.

[0170] When the target installation position 20 reaches the target detection station 1b, record the current time T and determine whether the sensor has recognized the identification component.

[0171] If the sensor detects the identification device, record the time T1 when the sensor detects the identification device;

[0172] Calculate T1-T to obtain the first difference value. If the first difference value exceeds the preset value, then compensate the working parameters of the turntable 2 drive mechanism based on the first difference value.

[0173] If the sensor does not recognize the identification object, after the turntable 2 continues to rotate, record the time T2 when the sensor recognizes the identification object;

[0174] The second difference value is obtained by calculating T2 - the dwell time of the electronic product at the target inspection station 1b. If the second difference value exceeds the preset value, the working parameters of the turntable 2 drive mechanism are compensated based on the second difference value.

[0175] In the above embodiment, zero-point calibration is performed directly using the unused mounting position 20 of the turntable 2, which will not affect the production cycle.

[0176] In particular, according to the embodiments disclosed in this application, the processes described above with reference to the flowcharts can also be implemented as computer software programs. For example, embodiments disclosed in this application include a computer program product comprising a computer program carried on a computer-readable medium, the computer program containing program code for performing the methods shown in the flowcharts.
