Description

Technical Field

[0001] This application relates to the field of servo motor drivers, and more specifically to a screw anti-missing detection device for servo motor drivers. Background Technology

[0002] A servo motor driver, or simply a servo driver, is the core control component of a servo system. By receiving commands from a host computer and feeding back the real-time status of the motor, it achieves high-precision closed-loop control of the servo motor's position, speed, and torque. It is widely used in automation scenarios where motion accuracy and dynamic response are extremely important.

[0003] In the manufacturing process of servo motor drivers, the assembly of the power board and control board is one of the core processes that determines the stability of product performance and operational safety. As a core component of high-precision motion control equipment, the servo motor driver's internal power board must bear the task of converting high voltage and high current electrical energy, while the control board is responsible for parsing instructions, processing feedback signals, and generating precise control logic. The reliable connection between the two directly affects the driver's signal transmission efficiency, heat dissipation performance, and anti-interference capability.

[0004] During actual assembly, due to factors such as the pressure of the assembly line cycle during manual operation, the small size of screws, and the low recognition of screw holes, or material jamming and positioning deviations in automated equipment, screws are easily missed. Missing screws leads to two major problems: first, insufficient rigidity of the circuit board connection, causing displacement or gaps due to vibration and temperature changes, resulting in performance failures such as decreased control accuracy and signal interruption; second, interruption of the heat dissipation path for power devices, leading to overheating and device burnout, and even safety risks such as short circuits and fires.

[0005] Existing solutions rely on manual re-inspection, which is inefficient and has a high rate of missed detections. Therefore, there is an urgent need for a device that can detect missed parts during the screw assembly process. Utility Model Content

[0008] A screw anti-missing detection device for a servo motor driver includes:

[0009] The detection device consists of a main body, several detection rods, a first baffle, several micro switches, and a display device.

[0010] The main body of the detection device is provided with a guide groove, which is used to support and fix the power board of the servo motor driver;

[0011] The first baffle is disposed on the main body of the detection device, and the first baffle is provided with a plurality of first through holes; the detection rod passes through the first through holes and passes through the first baffle.

[0012] The detection rod is provided with a reset device so that the detection rod can reciprocate through the first through hole and can contact the switch terminal of the micro switch and the screw of the servo motor driver.

[0013] The display device is electrically connected to the micro switch.

[0014] Furthermore, the screw anti-leakage detection device also includes: a second baffle, which is arranged parallel to the first baffle on the main body of the detection device. The second baffle is provided with a plurality of second through holes, and the switching end of the micro switch is installed on the second baffle through the second through holes.

[0015] Furthermore, the geometric centers of the first through hole and the second through hole are on the same horizontal line.

[0016] Furthermore, the distance between the first baffle and the second baffle is less than the length of the detection rod.

[0017] Furthermore, the number of microswitches and the number of the first through holes are the same.

[0018] Furthermore, the reset device includes an elastic element and a limiting block, the limiting block being disposed on the detection rod, and the elastic element being disposed between the limiting block and the first baffle.

[0019] Furthermore, the elastic element includes a spring, which is sleeved on the detection rod, the diameter of the spring being larger than the inner diameter of the first through hole and smaller than the outer diameter of the limiting block.

[0020] Furthermore, the top of the detection rod is provided with a crescent-shaped arc structure.

[0021] Furthermore, the detection rod is a cylinder with a keyway and a boss inside the first through hole. The boss slides in conjunction with the keyway so that the detection rod does not rotate when it reciprocates along the first through hole.

[0022] Furthermore, the detection rod is shaped like a polygonal column, and the shape of the first through hole is the same as the cross-sectional shape of the detection rod.

[0023] This application provides a hypergraph feature representation method based on fuzzy logic, which has the following advantages compared with the prior art:

[0046] See Figures 1 to 6 This application discloses a screw anti-missing detection device for a servo motor driver, comprising:

[0047] The detection device consists of a main body 100, several detection rods 200, a first baffle 300, several micro switches 400, and a display device 500.

[0048] The main body 100 of the detection device is provided with a guide groove 101, which is used to support and fix the servo motor driver 700. The size of the guide groove 101 is the same as the size of the power board 702 of the servo motor driver, so that the power board 702 of the servo motor driver can be embedded in the guide groove 101 and achieve the function of fixing the power board 702 of the servo motor driver.

[0049] The first baffle 300 is disposed on the main body 100 of the detection device, and the first baffle 300 is provided with a plurality of first through holes 301, wherein the first baffle 300 is vertically disposed on the main body 100 of the detection device.

[0050] The detection rod 200 passes through the first through hole 301 and is inserted into the first baffle 300; wherein, a sliding connection is formed between the detection rod 200 and the first through hole 301, so that the detection rod 200 can slide along the first through hole 301.

[0051] The detection rod 200 is provided with a reset device 201 so that the detection rod 200 can reciprocate through the first through hole 301 and can contact the switch terminal 401 of the micro switch and the screw 701 of the servo motor driver.

[0052] It is understandable that the detection rod 200 can reciprocate along the first through hole 301 through the reset device 201, and can contact the switch terminal 401 of the micro switch and the screw 701 of the servo motor driver. When the detection rod 200 contacts the switch terminal 401 of the micro switch and the screw 701 of the servo motor driver at the same time, it will trigger the sensing of the micro switch 400, so that the micro switch 400 can send out a corresponding signal.

[0053] The display device 500 is electrically connected to the micro switch 400 and is used to receive electrical signals emitted by the micro switch 400.

[0054] Specifically, the display device 500 responds accordingly to the electrical signal. For example, a green light may be displayed when the screw 701 of the servo motor driver is detected, and a red light may be displayed when the screw 701 of the servo motor driver is not detected.

[0055] In one embodiment of this application, the screw anti-leakage detection device further includes: a second baffle 600, the second baffle 600 and the first baffle 300 are arranged in parallel on the detection device body 100, the second baffle 600 is provided with a plurality of second through holes 601, and the switching end 401 of the micro switch is installed on the second baffle 600 through the second through holes 601.

[0056] Specifically, in this embodiment, the second baffle 600 and the first baffle 300 are arranged in parallel, and the micro switch 400 is fixed on the second baffle 600 through the second through hole 601 to ensure that the micro switch 400 will not loosen when the detection rod 200 and the micro switch 400 are in contact.

[0057] In one embodiment of this application, the geometric centers of the first through hole 301 and the second through hole 601 are on the same horizontal line.

[0058] Specifically, in this embodiment, since the detection rod 200 passes through the first through hole 301, and the switching end 401 of the micro switch is installed in the second through hole 601, the geometric centers of the first through hole 301 and the second through hole 601 are set on the same horizontal line to ensure that when the detection rod 200 reciprocates along the first through hole 301, it can accurately contact the switching end 401 of the micro switch.

[0059] In one embodiment of this application, the distance between the first baffle 300 and the second baffle 600 is less than the length of the detection rod 200.

[0060] Specifically, in this embodiment, the distance between the first baffle 300 and the second baffle 600 is set to be less than the length of the detection rod 200, so as to prevent the detection rod 200 from falling between the first baffle 300 and the second baffle 600 when it is reciprocating.

[0061] In one embodiment of this application, the number of detection rods 200 and micro switches 400 are the same.

[0062] Specifically, in this embodiment, the number of detection rods 200 and micro switches 400 is set to be the same, so that the missing screws 701 of multiple servo motor drivers can be detected at the same time, thereby improving the detection efficiency.

[0063] In one embodiment of this application, the reset device 201 includes an elastic element 2012 and a limiting block 2011. The limiting block 2011 is disposed on the detection rod 200, and the elastic element 2012 is disposed between the limiting block 2011 and the first baffle 300.

[0064] Specifically, in this embodiment, the reset device 201 includes an elastic element 2012 and a limiting block 2011. Through the combined action of the elastic element 2012 and the limiting block 2011, the detection rod 200 can be automatically reset when it is squeezed.

[0065] In one embodiment of this application, the elastic element 2012 includes a spring, which is sleeved on the detection rod 200. The diameter of the spring is larger than the inner diameter of the first through hole 301, and the diameter of the spring is smaller than the outer diameter of the limiting block 2011.

[0066] Specifically, in this embodiment, the elastic element 2012 is preferably a spring, and the diameter of the spring is set between the inner diameter of the first through hole 301 and the outer diameter of the limiting block 2011 to prevent the spring from sliding out of the inspection rod and the first through hole 301.

[0067] In one embodiment of this application, a crescent-shaped arc structure 203 is provided at the top of the detection rod 200.

[0068] It is understandable that since the screws 701 of the servo motor driver are generally round, in this embodiment, the top of the detection rod 200 is set as a crescent arc structure. This can prevent the detection rod 200 from slipping when it contacts the screws 701 of the servo motor driver, thereby making the top of the detection rod 200 fit the screws 701 of the servo motor driver more closely, thus improving the detection efficiency.

[0069] In one embodiment of this application, the detection rod 200 is a cylinder with a keyway 202. A boss 3011 is provided in the first through hole 301. The boss 3011 slides with the keyway 202 so that the detection rod 200 will not rotate when it reciprocates along the first through hole 301.

[0070] It is understandable that since a cylinder is prone to rotation during reciprocating motion, this could cause the detection rod 200 to slide during contact with the screw 701 of the servo motor driver. Therefore, in this embodiment, a boss 3011 is provided in the first through hole 301, and a keyway 202 that mates with the boss 3011 is provided on the detection rod 200. The boss 3011 can slide in the keyway 202, thus preventing the detection rod 200 from rotating during reciprocating motion.

[0071] In one embodiment of this application, the detection rod 200 is a polygonal prism structure (not shown in the figure), and the shape of the first through hole 301 is the same as the cross-sectional shape of the detection rod 200 (not shown in the figure).

[0072] Understandably, in order to prevent the detection rod 200 from rotating during reciprocating operation, in this embodiment, the detection rod 200 can be set as a polygonal prism structure, such as a quadrilateral prism structure, a hexagonal main body structure, and an octagonal prism structure. At the same time, in order for the detection rod 200 to pass through the first through hole 301, the shape of the first through hole 301 needs to be adapted to the detection rod 200, that is, the shape of the first through hole 301 is set to be the same as the cross-sectional shape of the detection rod 200.

[0073] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0074] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
