[0040] Refer to Figures 1 to 5, an embodiment of the first aspect of the present invention provides a positioning device for positioning a housing having a receiving cavity. The positioning device includes a mounting base 100, a support platform 200, a first positioning member 210, a second positioning member 220, a pushing component 300, and an elastic component 400. Among them, the mounting base 100 is provided with an adjustment hole 110 that extends along the X-axis direction. The support platform 200 is connected to the mounting base 100 and is used to support the housing. The first positioning member 210 is connected to the support platform 200, and the first positioning member 210 is used to abut and position the housing along the X-axis direction to ensure one side reference. The second positioning member 220 is connected to the support platform 200, and the second positioning member 220 is used to abut and position the housing along the Y-axis direction. The pushing component 300 is disposed above the support platform 200. The pushing component 300 includes a first driving member 310 and a pushing member 320. The first driving member 310 is used to drive the pushing member 320 to move, and the pushing member 320 is used to drive the housing to move along the Y-axis direction so that the housing can abut against the second positioning member 220. The elastic component 400 is disposed along the X-axis direction. The elastic component 400 includes a connecting member 410, a movable member 430, and an elastic member 420. The connecting member 410 is fixedly connected to the mounting base 100. One end of the elastic member 420 is connected to the movable member 430, and the other end of the elastic member 420 is connected to the connecting member 410. The elastic member 420 is used to drive the movable member 430 to move in a direction away from the connecting member 410. The movable member 430 includes a main body portion 433, a support portion 431, and a positioning portion 432. The support portion 431 and the positioning portion 432 are both connected to the main body portion 433 and pass through the adjustment hole 110. The support portion 431 is flush with the support platform 200 along the Z-axis direction. The support portion 431 is used to support the housing, and the positioning portion 432 is used to push the housing in a direction away from the first positioning member 210 until the first positioning member 210 abuts against the inner wall of the housing. The planes of the support platform 200 and the support portion 431 for supporting the housing are flush along the Z-axis direction, which can always support the housing during the housing positioning process and prevent the housing from shifting or tilting when moving along the X-axis and Y-axis directions. The elastic member 420 can be selected from one of a spring or a gas spring.

[0041] Specifically, when positioning is required, first move the movable member 430 towards the connecting member 410 to compress the elastic member 420. Subsequently, place the housing on the support table 200 and accommodate the positioning portions 432 provided by the first positioning member 210, the second positioning member 220, and the elastic component 400 in the accommodating cavity. Then, remove the force applied to the movable member 430, causing the movable member 430 to move away from the connecting member 410 under the action of the elastic member 420. The positioning portion 432 abuts against the inner wall of one side of the housing along the X-axis direction and drives the housing to move, so that the inner wall of the other side of the housing along the X-axis direction abuts against the first positioning member 210, achieving positioning in the X-axis direction. The first driving member 310 drives the pushing member 320 to push the housing to move along the Y-axis direction, causing the inner wall of the housing to abut against the second positioning member 220 to achieve positioning in the Y-axis direction. The positioning device can achieve the positioning of the housing in the X-Y plane within a certain size range through the compression of the elastic member 420 in the X-axis direction and the movement range of the pushing member 320 in the Y-axis direction. The structure is simple and convenient to use.

[0042] Refer to Figure 1 、 Figure 4 and Figure 5 In some embodiments, referring to FIGS. and, the positioning device further includes a base 500 and a driving component 600. The base 500 is arranged at an interval from the mounting base 100 along the X-axis direction. The driving component 600 is connected to the base 500. The driving component 600 includes an abutting member 610 and a second driving member 620. The abutting member 610 corresponds to the movable member 430. The second driving member 620 can drive the abutting member 610 to move to abut against the movable member 430, so as to drive the movable member 430 to move towards the connecting member 410. The second driving member 620 can drive the abutting member 610 to move along the X-axis direction to compress the elastic member 420. After the housing is placed on the support table 200, the second driving member 620 returns to its initial state, and the elastic member 420 generates a tendency to restore its original length and applies a force to the movable member 430 in the direction away from the first positioning member 210, causing the housing to move in the X-axis direction and abut against the first positioning member 210 to achieve positioning in the X-axis direction. The above positioning process can be automatically performed by driving the abutting member 610 by the second driving member 620 without manual operation, improving the positioning efficiency of the positioning device. In addition, the second driving member 620 can be selected as a cylinder.

[0043] Refer to Figure 1 and Figure 5, in some embodiments, the positioning device further includes a transfer component 800. The transfer component 800 includes a slide rail 820, a sliding member 830, and a third driving member 810. The slide rail 820 is fixedly connected to the base 500 and extends along the X-axis direction. The sliding member 830 is slidably connected to the slide rail 820. The driving component 600 is connected to the sliding member 830. The third driving member 810 can drive the sliding member 830 to slide along the slide rail 820. The sliding member 830 is provided with a sliding groove 831, and the slide rail 820 is inserted into the sliding groove 831. The driving component 600 is connected to the sliding member 830. The third driving member 810 drives the driving component 600 to move along the extension direction of the slide rail 820, which can adjust the distance between the driving component 600 and the mounting base 100. Without changing the stroke of the second driving member 620, the range of deformation of the elastic member 420 squeezed by the abutting member 610 can be adjusted, so that the positioning device can be adapted to the positioning of shells in a larger range. Among them, the third driving member 810 can be selected as a servo motor, which can accurately control the position of the driving component 600 on the guide rail and ensure the reliability of the positioning device.

[0044] Refer to Figure 1 and Figure 2 , in some embodiments, the first driving member 310 can also drive the pushing member 320 to rotate around the first driving member 310 as the rotation center. Before the shell is installed, the pushing member 320 is in a position perpendicular to the support table 200, reserving an avoidance space for the installation of the shell to facilitate the positioning parts 432 of the first positioning member 210, the second positioning member 220, and the movable member 430 to be accommodated in the accommodation cavity, and the support table 200 and the support part 431 of the movable member 430 support the shell. After the shell is installed in place, the elastic component 400 realizes the positioning in the X-axis direction, and after the pushing member 320 rotates to correspond to the shell, the shell is pushed to abut against the second positioning member 220 to realize the positioning in the Y-axis direction. The positioning device further includes a fixing member. The first driving member 310 is fixedly connected to the fixing member. The fixing member is connected to the base 500. The fixing member is provided with a waist-shaped hole 411 extending along the Y-axis direction to enable the pushing member 320 to adjust its position in the Y-axis direction to adapt to shells of different sizes. Specifically, the first driving member 310 is selected as a rotary clamping cylinder. The first driving member 310 can drive the pushing member 320 to rotate between a position perpendicular to the support table 200 and a position parallel to the support table 200, that is, it has the rotation ability of 90 degrees. During the process of pushing the shell to be positioned, the pushing member 320 rotates first and then pushes, and the process of returning to the initial position is opposite.

[0045] Refer to Figure 2, in some embodiments, the positioning device further includes a fastener 440. The connecting member 410 is further provided with a waist-shaped hole 411, and the mounting seat 100 is provided with a connecting hole. The waist-shaped hole 411 is arranged along the X-axis direction. The fastener 440 passes through the waist-shaped hole 411 and the connecting hole, and the connecting member 410 can move relative to the mounting seat 100 along the X-axis direction. The fastener 440 is provided with an external thread, and the connecting hole is provided with an internal thread. After the connecting member 410 adjusts its position along the X-axis direction, it is connected to the mounting seat 100 through the fastener 440 passing through the waist-shaped hole 411 and the connecting hole, so that the connecting member 410 is stably connected to the mounting seat 100. The elastic component 400 can realize the adaptive adjustment of the dimensions of different shells in the X-axis direction by adjusting the position of the connecting member 410 in the X-axis direction, so as to meet the positioning requirements of different shells.

[0046] Refer to Figure 1 , in some embodiments, the positioning device includes a plurality of elastic components 400. The mounting seat 100 is provided with adjustment holes 110 that are the same in number as and correspond one-to-one to the positioning parts 432. The plurality of elastic components 400 are arranged at intervals along the Y-axis direction. The supporting parts 431 and the positioning parts 432 provided on each elastic component 400 both pass through the corresponding adjustment holes 110 . The movable part 430 may include a plurality of positioning parts 432 and a plurality of supporting parts 431. The plurality of positioning parts 432 and the plurality of supporting parts 431 are both connected to the same connecting part 611. Each positioning part 432 and each supporting part 431 are arranged at intervals along the Y-axis direction. For example, when the shell is provided with a reinforcing rib, the plurality of supporting parts 431 can support the edge and the reinforcing rib of the shell at the same time, so as to increase the supporting stability of the shell. Or, when positioning a shell with a smaller dimension in the Y-axis direction, the accommodating cavity provided in the shell can accommodate only a part of the positioning parts 432 in the Y-axis direction and the supporting parts 431 can support the shell, so that the positioning device has the ability to position shells of different dimensions.

[0047] Refer to Figure 4 and Figure 5, in some embodiments, the positioning device further includes a base 500 and a driving component 600. The base 500 is spaced apart from the mounting base 100 in the X-axis direction. The driving component 600 is connected to the base 500. The driving component 600 includes a second driving member 620 and an abutting member 610. The abutting member 610 includes a connecting portion 611 and a plurality of abutting portions 612. The abutting portions 612 are connected to the connecting portion 611. The plurality of abutting portions 612 are spaced apart in the Y-axis direction. Each abutting portion 612 corresponds to each movable member 430. The second driving member 620 can drive the abutting member 610 to move to abut against the movable member 430, so as to drive the movable member 430 to move in a direction close to the connecting member 410. The second driving member 620 drives the abutting member 610 to move until each abutting portion 612 abuts against the corresponding movable member 430 and continues to move to compress the elastic members 420 corresponding to each movable member 430. The synchronism of the compression process is good and the compression process can be completed at one time, thereby improving the efficiency of housing positioning. The second driving member 620 can be selected as a cylinder.

[0048] In some embodiments, the positioning device includes a plurality of first positioning members 210. The movable member 430 includes a plurality of positioning portions 432. The plurality of positioning portions 432 are spaced apart in the Y-axis direction. The plurality of first positioning members 210 are spaced apart in the Y-axis direction. Each positioning portion 432 corresponds to each first positioning member 210. During the process of positioning the housing in the X-axis direction, the elastic member 420 returns to its original length, so that the plurality of first positioning members 210 simultaneously abut against the inner surface of the housing in the X-axis direction, thereby increasing the reliability and accuracy of housing positioning.

[0049] Referring to Figure 4 , in some embodiments, the positioning device further includes a sensor 700. The sensor 700 is connected to the driving component 600. The sensor 700 is used to detect the presence or absence of the housing. Specifically, the sensor 700 is connected to the connecting portion 611 and is disposed above the connecting portion 611 to achieve the detection and sensing function without affecting the use of the driving component 600. The sensor 700 is used to detect the presence or absence of the housing and transmit a signal to the industrial control computer.

[0050] In summary, the positioning device can position the housing within a certain size range. When the size difference of the housing to be positioned before and after is too large, the position adjustment of the elastic component 400 in the X-axis direction and the position adjustment of the pushing component 300 in the Y-axis direction can be used to cover the size of the new housing, so that while the positioning device has the automatic positioning function for the housing within a certain size range, it can also adjust and change the corresponding housing size range, and has a wide application range.

[0051] In the second aspect of the embodiments of the present invention, a detection system (not shown in the figure) is provided, which includes the positioning device, the detection device and the robot provided in the first aspect of the embodiments. Among them, the detection device is connected to the positioning device, and the detection device is used to detect the housing. The robot is used to carry and take out the housing to and from the positioning device, and is arranged on one side of the positioning device. The robot includes a mounting base 100, an arm group and a clamping component. The arm group includes several sequentially connected robotic arms. One end of the arm group is connected to the mounting base 100, and the clamping component is connected to the other end of the arm group. The clamping component is used to clamp the housing. The loading and unloading of the housing on the positioning device is realized through the movement of the arm group and the picking and placing of the clamping component. The detection system at least includes a CCD camera and a light source.
