[0065] Please refer to Figure 2 , which shows a partial structural schematic diagram of a workpiece detection device provided in an embodiment of the present application, including at least two detection members, at least two first sliding rails 4, at least three positioning fixtures and at least three second sliding rails 5;

[0066] The positioning fixture is used to limit and fix the workpiece 11 to be measured;

[0067] The detection member corresponds to the first sliding track 4 one-to-one, and the positioning fixture corresponds to the second sliding track 5 one-to-one;

[0068] The detection member is slidably connected to the first sliding track 4 and can move along the first sliding track 4 to a first preset detection position;

[0069] The positioning fixture is slidably connected to the second sliding track 5 and can move along the second sliding track 5 until the workpiece 11 to be tested moves to the second preset detection position;

[0070] The detection member located at the first preset detection position is used to detect the workpiece 11 to be detected located at the second preset detection position.

[0071] Optionally, the first preset detection position and the second preset detection position are both pre-set; wherein, when the detection device is located at the first preset detection position, the detection device can detect the workpiece to be measured; when the workpiece to be measured is located at the second preset detection position, the workpiece to be measured can be detected by the detection device at the first preset detection position.

[0072] In one example, when the workpiece to be measured moves to the second preset detection position, the position of a reference point on the workpiece to be measured coincides with the second preset detection position; for example, the position of the center point of the workpiece to be measured coincides with the second preset detection position.

[0073] The present application sets up two detection parts that move in coordination with three positioning fixtures, so that during detection, the two detection parts interact to detect the workpiece to be tested on the three positioning fixtures, thereby eliminating the need for the detection parts to wait during the detection process, greatly saving detection time and improving detection efficiency.

[0074] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the detection device 1 includes a first detection member 101 and a second detection member 102, and the positioning device 2 includes a first positioning fixture 201, a second positioning fixture 202 and a third positioning fixture 203;

[0075] It also includes a machine platform 7 and two first sliding rails 4, three second sliding rails 5 and three rotating components 6 fixedly arranged on the machine platform 7;

[0076] The first detecting member 101 and the second detecting member 102 respectively correspond to one of the first sliding rails 4 and are respectively slidably connected to the first sliding rails 4;

[0077] The first positioning fixture 201, the second positioning fixture 202 and the third positioning fixture 203 each correspond to one second sliding track 5, and the rotating assembly 6 corresponds to the second sliding track 5 one by one;

[0078] The first positioning fixture 201, the second positioning fixture 202 and the third positioning fixture 203 are respectively slidably connected to the second sliding track 5 through the rotating assembly 6;

[0079] Specifically, one end of the rotating assembly 6 is slidably connected to the second sliding track 5, and the other end is fixedly connected to any one of the first positioning fixture 201, the second positioning fixture 202 and the third positioning fixture 203;

[0080] The driving device 10 is capable of driving the rotating assembly 6 to reciprocate along the second sliding track 5, so as to drive the positioning fixture connected to the rotating assembly 6 to move along the second sliding track 5 toward or away from the second preset detection position;

[0081] Specifically, the driving device 10 is used to drive the first positioning fixture 201 , the second positioning fixture 202 , and the third positioning fixture 203 to perform reciprocating motion along the y-axis direction.

[0082] The driving device 10 is used to drive the rotating assembly 6 located at the second preset detection position to rotate around the target axis 12 by the preset angle according to the second preset frequency, so as to drive the positioning fixture connected to the rotating assembly 6 to rotate around the target axis 12 by the preset angle;

[0083] When the positioning fixture drives the workpiece 11 to move to the second preset detection position, the corresponding rotating assembly 6 of the positioning fixture can be driven to rotate around the target axis according to the second preset frequency to drive the workpiece to rotate by a preset angle.

[0084] The driving device 10 is also used to drive the first detection member 101 or the second detection member 102 to move along the first sliding track 4 to a first preset detection position, and drive the first detection member 101 or the second detection member 102 to move the preset distance along the preset direction of the first sliding track 4 according to the first preset frequency; the present application cooperates with the three positioning fixtures to detect through the two detection members set up. During the detection, the three positioning fixtures cooperate with the two detection members, so that the two detection members interact to detect the workpiece 11 to be tested on the three positioning fixtures, so that there is no need to wait during the detection process, thereby further improving the detection efficiency.

[0085] In an exemplary embodiment, Figure 6As shown, the first sliding track 4 may include a first sliding rail 401, a second sliding rail 402 and a fixing member 403;

[0086] The detection device 1 is slidably connected to the second slide rail 402; specifically, the second slide rail 402 can drive the detection device 1 to reciprocate along the z-axis direction.

[0087] One end of the fixing member 403 is fixedly connected to the second slide rail 402, and the other end is slidably connected to the first slide rail 401;

[0088] The driving device 10 drives the fixing member 403 to move along the first slide rail 401 and drives the detection device 1 to move along the second slide rail 402, so that the detection device 1 moves to the first preset detection position; specifically, the driving device 10 can drive the fixing member 403 to reciprocate along the first slide rail 401 in the horizontal plane along the x-axis direction.

[0089] The driving device is further configured to drive the fixing member 403 to move along the first slide rail 401 in the preset direction and by the preset distance according to the first preset frequency.

[0090] Specifically, the first sliding track 4 may be arranged above the second sliding track 5 ; the projection of the first sliding track 4 on the horizontal plane is perpendicular to the second sliding track 5 .

[0091] In one example, three second sliding rails 5 are arranged in parallel on the machine platform 7 , and the first sliding rail 401 and the second sliding rail 402 are arranged in parallel and mounted on the machine platform 7 through connecting columns.

[0092] In the embodiment of the present application, the first detection member 101 and the second detection member 102 each include a detection probe;

[0093] The control device is used to control the detection probe corresponding to the first detection member 101 and the detection probe corresponding to the second detection member 102 to detect the workpiece 11 to be detected respectively.

[0094] In one example, the first detection member 101 and the second detection member 102 are both independent detection probes. Further, the first detection member 101 and the second detection member 102 use independent detection probes to sequentially detect multiple positions to be measured on the workpiece 11 to be measured.

[0095] In the embodiments of this application, Figure 4 and Figure 5As shown, the first positioning fixture 201, the second positioning fixture 202 and the third positioning fixture 203 each include a base 301, a connecting rod mechanism 302, a first clamping jaw 303, a second clamping jaw 304 and a driving member 308;

[0096] The connecting rod mechanism 302 is fixedly arranged on the base 301;

[0097] The base 301 is fixedly connected to the rotating assembly 6; specifically, it can be fixedly connected to the rotating assembly via a fixing member.

[0098] The first clamping jaw 303 and the second clamping jaw 304 are both slidably connected to the base 301 , and the first clamping jaw 303 and the second clamping jaw 304 are used to clamp the workpiece 11 to be measured;

[0099] The driving member 308 is used to drive the connecting rod mechanism 302 to open or close, thereby pushing the first clamping jaw and the second clamping jaw 304 to move in opposite directions or towards each other.

[0100] In an exemplary embodiment, the linkage mechanism 302 may include two links, each of which has one end connected to the driving member 308 , one of which has the other end connected to the first clamping jaw 303 , and the other of which has the other end connected to the second clamping jaw 304 .

[0101] Specifically, one end of the connecting rod can be connected to the driving member 308 through a rotating shaft; preferably, one end of the rotating shaft can be fixedly connected to the connecting rod, and the other end can be rotatably connected to the driving member 308; the driving member 308 can drive the two rotating shafts to rotate in opposite directions around the central axis, and then drive one end of the two connecting rods to rotate synchronously with the rotating shaft, so that the other ends of the two connecting rods move in opposite directions or toward each other to achieve opening or closing.

[0102] The movement of the two connecting rods can drive the first clamping jaw 303 and the second clamping jaw 304 respectively connected to the two connecting rods to move in opposite directions or towards each other along the sliding groove of the base 301, thereby achieving the release or clamping of the workpiece 11 to be measured.

[0103] In the embodiments of this application, Figure 4 As shown, the positioning fixture further includes an angle limiter 305, a bracket plate 306 and a connecting member 307;

[0104] The support plate 306 is fixedly connected to the base 301 via the connecting member 307;

[0105] The support plate 306 is arranged around the first clamping jaw 303 and the second clamping jaw 304, and the first clamping jaw 303 and the second clamping jaw 304 are respectively slidably connected to the support plate 306 through a shaft pin;

[0106] Specifically, the support plate 306 is provided with a through slot, and a tray is provided along the center of the through slot for placing the workpiece to be measured. The first clamping jaw 303 and the second clamping jaw 304 are both located in the through slot and are symmetrically arranged along the tray. The first clamping jaw 303 and the second clamping jaw 304 are used to clamp the workpiece 11 to be measured on the tray.

[0107] Furthermore, the first clamp 303 and the second clamp 304 are fixedly connected to the axle pin on the side away from the workpiece to be measured, and the axle pin is slidably connected to the through hole opened on the bracket plate 306; this design enables the side wall of the bracket plate 306 to limit the movement distance of the first clamp 303 and the second clamp 304, thereby improving the stability of the positioning fixture.

[0108] Furthermore, the contact surfaces between the first clamping jaw 303 and the second clamping jaw 304 and the workpiece 11 to be measured are arc-shaped surfaces;

[0109] The first clamping jaw 303 and the second clamping jaw 304 are both in point contact with the workpiece 11 to be measured.

[0110] The point-to-point contact method provided in the present application is more stable than other point-to-surface contacts or surface-to-surface contacts, and reduces the unstable clamping caused by an excessively large contact surface.

[0111] The angle limiting member 305 is disposed on a side of the support plate 306 away from the base 301 and is used to limit the workpiece 11 to be measured.

[0112] Specifically, the angle limiter 305 is located between the first clamping jaw 303 and the second clamping jaw 304. The angle limiter 305 may include a protruding portion and a fixing portion. The fixing portion is fixedly connected to the bracket plate 306. The protruding portion is located on the side of the tray away from the base 301 and is adapted to the opening portion of the workpiece to be measured 11. By limiting the position of the opening portion of the workpiece to be measured 11, the position of the workpiece to be measured 11 is limited.

[0113] In the embodiment of the present application, the driving device 10 may include a plurality of driving modules. Specifically, each detection component and each positioning fixture corresponds to a driving module.

[0114] Specifically, each rotating assembly 6 also corresponds to a driving module. This arrangement can facilitate the independent operation of each component.

[0115] In the embodiment of the present application, a sensor 8 is further included, and the sensor 8 is communicatively connected to the control device;

[0116] The sensor 8 is used to detect the distance information between the upper surface of the workpiece 11 to be measured and the upper surface of the positioning device 2, and send the distance information to the control device;

[0117] The control device is used to receive distance information and control the driving device to drive the detection device 1 to adjust its position based on the distance information and a preset detection height. The preset detection height can be the detection distance between the lower surface of the detection device 1 and the upper surface of the workpiece 11 when the detection device 1 detects the workpiece 11; it is a calibration value.

[0118] Specifically, when the distance information is equal to the preset detection height, the detection device 1 can be directly controlled to detect the workpiece 11 to be detected. When the distance information is not equal to the preset detection height, the position of the detection device is adjusted until the distance information is equal to the preset detection height.

[0119] Specifically, the sensor 7 may be a laser device, and may be disposed on a side of the machine 7 close to the material position of the positioning fixture to facilitate detection of the above-mentioned distance information.

[0120] In the embodiments of this application, Figure 7 As shown, the workpiece detection device further includes a frame 9;

[0121] The driving device 10 , the control device, the detection device 1 , and the positioning device 2 are all disposed in the frame 9 .

[0122] Specifically, the control device can be integrated on the frame 9; a plurality of structures adapted to the driving device 10, the detection device 1 and the positioning device 2 are provided in the frame 9; so that the driving device 10 located in the frame 9 can drive the detection device 1 and the positioning device 2 to operate normally.

[0123] The working principle of the workpiece detection equipment in this application is as follows:

[0124] When the workpiece detection device 11 is required to perform detection, the first positioning fixture 201 is driven in sequence to drive the workpiece to be detected 11 to the first fixture detection position corresponding to the first detection member 101, and the first detection member 101 is controlled to detect the workpiece to be detected 11 on the first positioning fixture 201; the second positioning fixture 202 is driven to drive the workpiece to be detected to the second fixture detection position corresponding to the second detection member 102, and the second detection member 102 is controlled to detect the workpiece to be detected 11 on the second positioning fixture 202;

[0130] Please refer to Figure 8 , which shows a flow chart of a control method for a workpiece detection device provided in an embodiment of the present application. This specification provides method operation steps as described in the embodiment or flow chart, but is based on conventional; or non-creative labor may include more or fewer operation steps. The order of steps listed in the embodiment is only one way of executing the steps among many, and does not represent the only execution order. The control method for the workpiece detection device can be executed in the order of the methods shown in the embodiment or the accompanying drawings. Specifically, Figure 8 As shown, the method includes:

[0131] S801, when it is detected that the first detection member detects the first workpiece to be measured located on the first positioning fixture and the second detection member detects the second workpiece to be measured located on the second positioning fixture, a target detection member is determined from the first detection member and the second detection member, and the target detection member is the detection member that completes the detection of the workpiece to be measured earlier among the first detection member and the second detection member.

[0132] In an embodiment of the present application, the workpiece detection device includes a first positioning jig, a second positioning jig, and a third positioning jig, three positioning jigs, and the detection piece includes a first detection piece and a second detection piece.

[0133] Optionally, the first detection member and the second detection member can respectively detect the workpiece to be tested on different positioning fixtures. The detection process and total detection time of each workpiece to be tested by the first detection member and the second detection member can be the same. In this embodiment, the loading time of the workpiece to be tested on different positioning fixtures is different, and the corresponding start time of the first detection member and the second detection member on the workpiece to be tested is also different.

[0134] Optionally, the remaining time for each of the first inspection workpiece and the second inspection workpiece to complete inspection can be obtained, and the inspection workpiece that completes inspection of the workpiece to be inspected earlier can be determined based on the two remaining inspection times.

[0135] S802 , controlling the third positioning fixture to drive the third workpiece to be measured to move to a target preset detection position, where the target preset detection position is the position of the third workpiece to be measured when the target detection component is used to detect the third workpiece to be measured.

[0136] In the embodiment of the present application, the target preset detection position may be a preset detection position.

[0137] Optionally, when the third workpiece to be measured is located at the target preset detection position, the third workpiece to be measured can be detected by the detection component.

[0138] In one example, when the third workpiece to be measured moves to the target preset detection position, the position of a reference point on the third workpiece to be measured coincides with the target preset detection position; for example, the position of the center point of the third workpiece to be measured coincides with the target preset detection position.

[0139] Furthermore, the target preset detection position may be a preset detection position corresponding to the first detection member or a preset detection position corresponding to the second detection member.

[0140] Optionally, the third positioning jig may be controlled to move along a second sliding track corresponding to the third positioning jig to a target preset detection position.

[0141] S803, when it is detected that the target detection member completes the detection of the target workpiece, controlling the target detection member to move to the target detection position and detect the third workpiece to be detected. The target detection position is a position where the target detection member can detect the workpiece to be detected.

[0142] In the embodiment of the present application, the target detection component completing the detection of the target workpiece to be measured can indicate that all the positions to be measured on the target workpiece to be measured have completed the detection, and the corresponding target detection component completes the detection task of the target workpiece to be measured.

[0143] Optionally, the target detection member may be controlled to move along a first sliding track corresponding to the target detection member to a target detection position.

[0144] In this embodiment, two detection parts are set up to cooperate with three positioning fixtures for detection. During detection, the three positioning fixtures cooperate with the two detection parts, so that the two detection parts interactively detect the workpieces to be tested on the three positioning fixtures, so that the detection parts do not need to wait during the detection process, which greatly saves the detection time and improves the detection efficiency.

[0145] In an exemplary embodiment, Figure 9 , which is a flow chart of a method for determining a target detection component provided in an embodiment of the present application; the details are as follows.

[0146] S901, when it is detected that the first detection member detects the first workpiece to be measured located on the first positioning fixture and the second detection member detects the second workpiece to be measured located on the second positioning fixture, obtain the remaining time of the first detection member completing the first detection of the first workpiece to be measured and the remaining time of the second detection member completing the second detection of the second workpiece to be measured.

[0147] In the embodiment of the present application, the first remaining detection time may refer to the time period from the current moment to the moment when the detection of the first workpiece to be detected is completed. The second remaining detection time may refer to the time period from the current moment to the moment when the detection of the second workpiece to be detected is completed.

[0148] Optionally, a first unmeasured number of unmeasured positions on the first workpiece and a single detection time required to complete detection of each position may be obtained; and a remaining time for the first detection may be determined based on the single detection time and the first unmeasured number.

[0149] In one example, the product of the single detection duration and the first unmeasured quantity may be determined as the first detection remaining duration.

[0150] Optionally, a second unmeasured number of unmeasured positions on the second workpiece and a single detection time required to complete detection of each position may be obtained; and a remaining time for the second detection may be determined based on the single detection time and the second unmeasured number.

[0151] In one example, the product of the single detection duration and the second unmeasured quantity may be determined as the second detection remaining duration.

[0152] S902, determining the shorter target detection remaining time from the first detection remaining time and the second detection remaining time;

[0153] S903: Determine the detection part corresponding to the remaining target detection time as the target detection part.

[0154] In this embodiment, the present application completes the remaining detection time of the workpiece to be tested by the first detection part and the second detection part respectively, and can accurately determine the target detection part; ensure that when the workpiece to be tested is tested in the next round, the target preset detection position reached by the third workpiece to be tested corresponds to the target detection position that can be reached by the target detection part, avoiding the erroneous waiting of the third workpiece to be tested and further improving the detection efficiency.

[0155] In an exemplary embodiment, Figure 10 , which is a schematic diagram of a third DUT detection method provided in an embodiment of the present application; the details are as follows.

[0156] S1001, when it is detected that the target detection member has completed the detection of the target workpiece to be detected, controlling the target detection member to move to the target detection position;

[0157] Optionally, the target detection member may be controlled to move in a direction close to the target detection position until the target detection member moves to the target detection position.

[0158] S1002, when it is detected that the third workpiece to be measured rotates around the target axis by a preset angle, the target detection part is controlled to move a preset distance along a first preset direction to realize the detection of the third workpiece to be measured; wherein, the target axis is perpendicular to the horizontal plane where the third workpiece to be measured is located, the projection of the trajectory of the target detection part moving the preset distance in the horizontal plane intersects with the edge line of the third workpiece to be measured, and the first preset direction is parallel to the horizontal plane.

[0159] In this embodiment of the present application, the preset angle may be a predetermined value of the angle change during each rotation of the third workpiece to be measured, for example, 21°. The preset distance may be the distance the detection head of the target detection member moves during each inspection of the third workpiece to be measured; for example, it may be 10 mm. The first preset direction may refer to the direction in which the target detection member can detect the third workpiece to be measured during movement of the target detection member in that direction for the preset distance; correspondingly, the target detection member may perform linear motion along the first preset direction.

[0160] Optionally, the third workpiece to be measured may include multiple positions to be measured, and the target detection component may detect each position to be measured in the third workpiece to be measured in turn.

[0161] Optionally, the relative detection distance between the third workpiece to be measured and the target detection part can be obtained; when the relative detection distance meets the preset detection height, the target detection part is triggered to control the movement to the target detection position and detect the third workpiece to be measured. The relative detection distance can refer to the actual distance in the height direction between the upper surface of the third workpiece to be measured and the lower detection surface of the target detection part; the preset detection height can refer to the detection distance between the lower surface of the target detection part and the upper surface of the third workpiece to be measured when the target detection part detects the third workpiece to be measured. The relative detection distance meeting the preset detection height can indicate that the actual distance in the height direction between the third workpiece to be measured and the target detection part is equal to the preset detection distance.

[0162] When the relative detection distance does not meet the preset detection height, the position of the target detection part is adjusted until the relative detection distance meets the preset detection height.

[0163] Specifically, the position of the target detection component in the z-axis direction can be adjusted to increase or decrease the relative detection distance, thereby making the relative detection distance equal to the preset detection height.

[0164] In an exemplary embodiment, a first distance between the upper surface of the third workpiece to be measured and the upper surface of the third positioning fixture, and a second distance between the lower surface of the target detection part and the upper surface of the third positioning fixture can be obtained; based on the first distance and the second distance, the relative detection distance of the lower surface of the target detection part relative to the upper surface of the third workpiece to be measured is determined.

[0165] Furthermore, the difference between the second distance and the first distance may be determined as the relative detection distance of the lower surface of the target detection component relative to the upper surface of the third workpiece to be detected.

[0166] In this embodiment, by controlling the target detection part to move a preset distance along the first preset direction when the third workpiece to be measured rotates around the target axis at a preset angle, repeated and invalid movements of the target detection part are avoided, the time for detecting the third workpiece to be measured is greatly shortened, and the detection efficiency is improved.

[0167] In an exemplary embodiment, Figure 11 , which is a flow chart of a detection method for a first position to be measured provided in an embodiment of the present application; the details are as follows.

[0168] S1101 , controlling the third workpiece to be measured to rotate around the target axis by a preset angle until a first position to be measured among a plurality of positions to be measured is located at a detection position corresponding to a target detection position.

[0169] In the embodiment of the present application, the first position to be measured may refer to the first position to be measured after the third workpiece to be measured rotates once through a preset angle at the target preset detection position. This position may be any position to be measured on the third workpiece to be measured. For example, in the case of a circular workpiece to be measured, this position may be the first position to be measured near the opening of the third workpiece to be measured.

[0170] Optionally, after the third workpiece to be measured located at the target preset detection position is controlled to rotate by a first preset angle, the first position to be measured moves to the detection position of the target detection member corresponding to the target detection position.

[0171] S1102, controlling the target detection component to move a preset distance along a first preset direction, and detecting a first position to be detected during the movement.

[0172] In an embodiment of the present application, when it is detected that the first position to be measured moves to the detection position, the target detection part is controlled to move a preset distance along the first preset direction, and the projection of its movement trajectory on the horizontal plane where the third workpiece to be measured is located intersects with the first position to be measured, thereby realizing the detection of the first position to be measured.

[0173] In this embodiment, the third workpiece to be measured rotates, and the target detection component cooperates with the movement to detect the first position to be measured, which can quickly and accurately detect the first position to be measured.

[0174] In an exemplary embodiment, Figure 12 , which is a flow chart of a detection method for multiple positions to be measured provided by an embodiment of the present application; the details are as follows.

[0175] S1201: Control the third workpiece to be measured to rotate around the target axis by a preset angle until the first position to be measured among the multiple positions to be measured is located at a detection position corresponding to the target detection position.

[0176] S1202: Control the target detection component to move a preset distance along a first preset direction, and detect a first position to be detected during the movement.

[0177] S1203, controlling the third workpiece to be measured to rotate around the target axis by a preset angle until the second position to be measured is in the detection position; the first position to be measured and the second position to be measured are arranged adjacent to each other.

[0178] S1204, controlling the target detection component to move a preset distance along a second preset direction, and detecting a second position to be detected during the movement; the second preset direction is opposite to the first preset direction.

[0179] In an embodiment of the present application, the target detection part moves in a straight line along the second preset direction, and its motion trajectory is the same as the motion trajectory of the target detection part moving along the first preset direction; the projection of its motion trajectory on the horizontal plane where the third workpiece to be measured is located has an intersection with the second position to be measured, thereby realizing the detection of the second position to be measured.

[0180] S1205, determining whether the second position to be measured is the target position to be measured; wherein the target position to be measured may be the last position to be detected on the third workpiece to be measured;

[0181] S1206: If yes, control the third workpiece to be tested to leave the second preset testing position.

[0182] If not, steps S1201 - S1204 are repeated until the second position to be measured is the target position to be measured.

[0183] In this embodiment, the detection process is as follows: Figure 13 As shown, the detection path is as follows Figure 14 The detection path shown.

[0184] In this embodiment, the present application realizes detection of each position to be measured on the third workpiece to be measured by rotating the third workpiece to be measured by a preset angle, and the target detection part moves along the first preset direction or the second preset direction, and detects each position to be measured on the third workpiece to be measured during this alternating reciprocating motion. This not only reduces the invalid movement of the target detection part, but also greatly shortens the detection time of the third workpiece to be measured, thereby improving the detection efficiency.

[0185] In an exemplary embodiment, Figure 15 , which is a flow chart of a cyclic detection method for multiple workpieces to be tested provided by an embodiment of the present application, as follows.

[0187] S1502: Control the third positioning fixture to move the third workpiece to be measured to a target preset detection position, where the target preset detection position is the position of the third workpiece to be measured when the target detection component is used to detect the third workpiece to be measured;

[0188] S1503, when it is detected that the target detection member completes the detection of the target workpiece, controlling the target detection member to move to the target detection position and detect the third workpiece to be detected. The target detection position is a position where the target detection member can detect the workpiece to be detected.

[0189] S1504: When it is detected that the target detection component completes the detection of the target workpiece to be detected, the target positioning fixture where the target workpiece to be detected is located is controlled to move to a preset unloading position.

[0190] In the embodiment of the present application, the target positioning fixture is a positioning fixture for holding the target workpiece to be tested. The preset unloading position can be a pre-set position for placing the workpiece to be tested on the positioning fixture or removing the workpiece to be tested from the positioning fixture after completion of the test.

[0191] When it is detected that the target detection part completes the detection of the target workpiece to be detected, the target positioning fixture is controlled to move along the second sliding track to the preset unloading position, thereby driving the target workpiece to be detected to move to the preset unloading position.

[0192] S1505, determining whether to replace the target workpiece to be measured on the target positioning fixture with a new workpiece to be measured;

[0193] In an exemplary embodiment, S1506 , if the target workpiece to be measured on the target positioning fixture is not replaced with a new workpiece to be measured, the motion control of the target positioning fixture is stopped.

[0194] In another exemplary embodiment, when the target workpiece to be measured on the target positioning fixture is replaced with a new workpiece to be measured, the target detection part determination step, the motion control step of the third workpiece to be measured and the detection step of the third workpiece to be measured are repeated until the detection of each workpiece to be measured is completed.

[0195] In this embodiment, the present application realizes the detection of each workpiece to be tested by the sequential reciprocating motion of each positioning fixture; so that the test piece does not need to wait during the detection process, which greatly saves the detection time and improves the detection efficiency.
