[0039] For ease of description, we define three mutually perpendicular coordinate axes in space as the X-axis, Y-axis, and Z-axis. The direction along the X-axis is vertical, the direction along the Y-axis is horizontal, and the direction along the Z-axis is vertical. The X-axis and Y-axis are two mutually perpendicular coordinate axes on the same horizontal plane, and the Z-axis is the vertical coordinate axis.

The XY-plane is horizontal, and the XZ-plane and YZ-plane are both vertical, with the XZ-plane perpendicular to the YZ-plane. Movement along these three axes in space refers to movement along the three mutually perpendicular axes in space, specifically movement along the X, Y, and Z axes. Planar movement, on the other hand, refers to movement within the XY-plane.
[0040] Please see Figures 1 to 3The screw height detection mechanism provided in this application embodiment will now be described. This screw height detection mechanism is used to cooperate with assembly 10, which includes a housing body 20, a motor end cover 30, and a screw body 40. The housing body 20 has a first mounting hole 201, and the motor end cover 30 has a second mounting hole 301 aligned with it. The screw body 40 passes through the second mounting hole 301 and is locked in the first mounting hole 201. The first mounting hole 201 can be a screw hole. There are multiple first mounting holes 201, second mounting holes 301, and screw bodies 40; in this application embodiment, there can be three first mounting holes 201, second mounting holes 301, and screw bodies 40 to improve the connection stability between the motor end cover 30 and the housing body 20. The screw height detection mechanism includes a support base 1, a height detection pin 2, a detection lifting assembly 3, and a detection moving assembly 4. Optionally, the height detection pin 2 is mounted on the support base 1 and is used to detect the installation height of the screw body 40. If the height of the screw body 40 detected by the height detection needle 2 differs from the target value, the screw body 40 is determined to be improperly installed; if the height of the screw body 40 detected by the height detection needle 2 is within the target value range, the screw body 40 is determined to be properly installed. The height detection needle 2 can be any commonly used accessory on the market, and will not be described in detail here. The detection lifting assembly 3 is connected to the support base 1. The detection lifting assembly 3 can drive the height detection needle 2 to move closer to or further away from the screw body 40, that is, the detection lifting assembly 3 can drive the height detection needle 2 to move up and down along the Z-axis. The detection moving assembly 4 is connected to the detection lifting assembly 3. The detection moving assembly 4 can drive the height detection needle 2 to reciprocate, that is, the detection moving assembly 4 can drive the height detection needle 2 to reciprocate along the Y-axis. This structure supports the height detection pin 2 via the support base 1; the detection moving component 4 drives the detection lifting component 3 and the height detection pin 2 to reciprocate, moving the pin 2 to a position directly above the screw body 40; the detection lifting component 3 drives the pin 2 to descend and approach the screw body 40, thus detecting the installation height of the screw body 40. In this way, the screw height detection mechanism can automatically detect the installation height of the screw body 40 connecting the housing 20 and the motor end cover 30, eliminating manual detection work and improving detection efficiency and accuracy.
[0041] In one embodiment, see Figure 3As a specific embodiment of the screw height detection mechanism provided in this application, the detection lifting assembly 3 includes a detection lifting member 31 installed on the output end of the detection moving assembly 4 and a detection sliding plate 32 connected to the output end of the detection lifting member 31. The support base 1 is slidably installed on the detection sliding plate 32. The detection lifting assembly 3 also includes an elastic member 33, which is disposed between the detection sliding plate 32 and the support base 1. One end of the elastic member 33 abuts against the detection sliding plate 32, and the other end of the elastic member 33 abuts against the support base 1. The detection lifting member 31 can be a cylinder, electric cylinder, etc.; the elastic member 33 can be a spring. In this structure, when the detection lifting member 31 drives the support base 1 and the height detection needle 2 to descend, after the bottom of the height detection needle 2 contacts the top of the screw body 40, if the height detection needle 2 continues to descend, the elastic member 33 can buffer and protect the height detection needle 2, preventing damage from hard contact between the height detection needle 2 and the screw body 40.
[0042] In one embodiment, see Figure 3 As a specific embodiment of the screw height detection mechanism provided in this application, the detection lifting assembly 3 further includes a sliding guide rod 34. One end of the sliding guide rod 34 is mounted on the support base 1, and the other end of the sliding guide rod 34 passes through the detection sliding plate 32; the elastic element 33 is sleeved on the sliding guide rod 34. This structure, on the one hand, can support and position the elastic element 33 through the sliding guide rod 34; on the other hand, it can also position the support base 1 to reciprocate and lift along the Z-axis direction.
[0043] Optionally, the support base 1 and the detection sliding plate 32 can be connected by a guide rail pair, which extends along the Z-axis. This structure improves the reliability of the support base 1 reciprocating up and down on the detection sliding plate 32 through the guide rail pair.
[0044] In one embodiment, see Figure 3 As a specific embodiment of the screw height detection mechanism provided in this application, a plurality of clamping guide rods 11 are installed on the support base 1, and the plurality of clamping guide rods 11 are arranged in a circular array. The plurality of clamping guide rods 11 can be installed at the bottom of the support base 1; each clamping guide rod 11 is detachably connected to the support base 1, facilitating the assembly and disassembly of each clamping guide rod 11. With this structure, when the support base 1 descends, the plurality of clamping guide rods 11 can cooperate with the top of the motor end cover 30 to abut, thereby clamping and fixing the motor end cover 30 and improving the detection accuracy of the height detection needle 2 on the installation height of the screw body 40; on the other hand, it also limits the lifting stroke of the support base 1.
[0045] In one embodiment, see Figure 3As a specific embodiment of the screw height detection mechanism provided in this application, the number of height detection pins 2 is multiple, arranged in a circular array, surrounding multiple clamping guide rods 11. This structure allows for simultaneous detection of multiple screw bodies 40 via multiple height detection pins 2, thus improving detection efficiency. Specifically, the number of height detection pins 2 is the same as the number of screw bodies 40. Alternatively, the number of height detection pins 2 can be three.
[0046] In one embodiment, see Figure 2 The bottom of the motor end cover 30 extends outward with a flange 302, on which a second mounting hole 301 is provided. The length of each height detection pin 2 extending out of the bottom of the support base 1 is greater than the length of each clamping guide rod 11 extending out of the bottom of the support base 1. In this way, the multiple clamping guide rods 11 can cooperate with the top of the motor end cover 30 to abut, and the multiple height detection pins 2 can abut with the multiple screw bodies 40 to achieve detection.
[0047] In one embodiment, see Figure 1 As a specific embodiment of the screw height detection mechanism provided in this application, the detection moving component 4 includes a detection moving plate 41 supporting the detection lifting component 3, a detection moving power unit 42 for driving the detection moving plate 41 to reciprocate, and a detection moving bracket 43 supporting the detection moving power unit 42; the output end of the detection moving power unit 42 is connected to the detection moving plate 41. The detection moving power unit 42 can be a cylinder / electric cylinder / screw drive mechanism, a linear motor, etc. In this structure, the detection moving power unit 42 can drive the detection moving plate 41 to reciprocate along the Y-axis, thereby driving the height detection needle 2 to reciprocate along the Y-axis, so as to move the height detection needle 2 to a position directly above the screw body 40.
[0048] In one embodiment, see Figure 1 As a specific embodiment of the screw height detection mechanism provided in this application, the screw height detection mechanism further includes a calibration bracket 5 and a calibration base 6 mounted on the calibration bracket 5. The mounting height of the calibration base 6 is the same as the target mounting height of the screw body 40. This structure, before the height detection needle 2 performs height detection, engages the height detection needle 2 with the calibration base 6 to perform the detection, thereby achieving calibration and resetting of the height detection needle 2, and improving the detection accuracy of the height detection needle 2 on the screw body 40.
[0049] In one embodiment, see Figure 1As a specific embodiment of the screw height detection mechanism provided in this application, the screw height detection mechanism further includes a material transfer and clamping assembly 7 for clamping the assembly 10. The material transfer and clamping assembly 7 is installed at the output end of the detection and movement assembly 4. With this structure, the assembly 10 can be removed after height detection via the material transfer and clamping assembly 7. For example, when the height detection needle 2 detects that the screw body 40 of the assembly 10 is not properly installed, the defective assembly 10 can be removed to the waste recycling station via the material transfer and clamping assembly 7.
[0050] In one embodiment, see Figure 1 The material transfer and clamping assembly 7 is installed on the detection moving plate 41, that is, the detection moving power unit 42 can drive the detection lifting assembly 3 and the material transfer and clamping assembly 7 to move synchronously along the Y-axis.
[0051] In one embodiment, see Figure 4 As a specific embodiment of the screw height detection mechanism provided in this application, the material handling and clamping assembly 7 includes a clamping member 71 for clamping the assembly 10, a clamping seat 72 for supporting the clamping member 71, and a clamping lifting member 73 for driving the clamping seat 72 to rise and fall. The clamping lifting member 73 is installed at the output end of the detection and moving assembly 4, and the output end of the clamping lifting member 73 is connected to the clamping seat 72. The clamping lifting member 73 can be a cylinder, electric cylinder, etc. In this structure, the clamping member 71 can be driven to descend and approach the lifting member by the clamping lifting member 73, and the assembly 10 can be clamped and fixed by the clamping member 71. The clamped assembly 10 can then be removed by the detection and moving assembly 4.
[0052] In one embodiment, see Figure 4 As a specific embodiment of the screw height detection mechanism provided in this application, the clamping component 71 includes a clamping power component 711 and two clamping arms 712. The clamping power component 711 is mounted on the clamping base 72, and the two clamping arms 712 are slidably mounted on the clamping power component 711 along a first direction. The clamping power component 711 is connected to the two clamping arms 712 respectively. Each clamping arm 712 has a clamping notch 7121, and the inner side of each clamping notch 7121 is provided with an anti-slip seat 7122. The clamping power component 711 can be a cylinder, electric cylinder, etc.; the first direction is the Y-axis direction. With this structure, the clamping power component 711 can drive the two clamping arms 712 to move closer or further apart to achieve the picking and placing of the assembly 10. The two clamping notches 7121 and the anti-slip seats 7122 can improve the clamping degree of the assembly 10.
[0053] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
