[0001] The utility model relates to the technical field of motor assembly, in particular to a pin insertion detection device with an indefinite position and a motor assembly production line. Background Art
[0002] When a flat wire motor is performing winding braiding, pins need to be inserted into the installation grooves of the winding braiding equipment. The pins are usually placed on a tray. After a pin is taken away, the tray is conveyed by a wire body to the next station. During the conveying process of the tray, if there is a pin on the tray, the pin needs to be removed before conveying.
[0003] In the actual detection process, for the situation where there are pins on the tray, the positions and quantities of the pins are random, and there are many combination situations. The diameter of the pin is usually less than 4 mm, so it is not easy to be detected by a photoelectric sensor or an area sensor, and the cost of detection by an imaging system is relatively high. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a pin insertion detection device with an indefinite position, which can accurately detect whether there is a pin in any positioning hole on the tray, and has a simple structure, low cost and high detection efficiency.
[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0011] Optionally, the connecting component includes a guide post and a guide sleeve. The guide sleeve is connected to the wire body, the first end of the guide post is connected to the blocking rod, and the second end of the guide post is movably inserted through the guide sleeve along the conveying direction of the wire body.
[0012] Optionally, the connecting component further includes an elastic member and a fixing member. The first end of the guiding column is connected to the blocking rod through the fixing member, and the elastic member is sleeved on the guiding column and located between the fixing member and the guiding sleeve.
[0013] Optionally, the fixing member is provided with a first fixing hole and a second fixing hole. The blocking rod passes through the first fixing hole, and the first end of the guiding column passes through the second fixing hole.
[0014] Optionally, the second end of the guiding column is provided with an anti - detachment portion, which can prevent the guiding column from detaching from the guiding sleeve.

[0022] Beneficial effects:
[0023] The pin insertion detection device with variable positions provided by the present utility model sets a blocking rod on the line body, and detects the position of the blocking rod through a detection element, so as to judge whether there is a pin on the tray. When there is no pin on the tray, the tray can be conveyed through the avoidance interval; when there is a pin in any positioning hole on the tray, during the movement of the tray, the pin will push the blocking rod to move from the first position to the second position, and when the detection element detects that the blocking rod reaches the second position, it sends an electrical signal.

[0035] See Figure 1 and Figure 2, this embodiment provides a pin insertion detection device 400 with an indefinite position for detecting whether there is a pin 200 in any positioning hole of the tray 100 on the line body 300. The pin insertion detection device 400 with an indefinite position includes a pair of connection components 430, a blocking rod 410, and a detection element 420. The pair of connection components 430 are connected to the line body 300, and the pair of connection components 430 are arranged oppositely along the direction perpendicular to the conveying direction of the line body 300. The blocking rod 410 is movably located between the pair of connection components 430, and there is an avoidance interval allowing the tray 100 to pass between the blocking rod 410 and the conveying table surface of the line body 300. When there is a pin 200 in any positioning hole of the tray 100, the pin 200 can contact the blocking rod 410 and push the blocking rod 410 to move from the first position to the second position. The detection element 420 is arranged on one side of the connection component 430, and the detection element 420 is configured to send an electrical signal when detecting that the blocking rod 410 is in the second position.
[0036] The above-mentioned pin insertion detection device 400 with an indefinite position determines whether there is a pin 200 on the tray 100 by setting the blocking rod 410 on the line body 300 and detecting the position of the blocking rod 410 through the detection element 420. When there is no pin 200 on the tray 100, the tray 100 can be conveyed through the avoidance interval; when there is a pin 200 in any positioning hole of the tray 100, during the movement of the tray 100, the pin 200 will push the blocking rod 410 to move from the first position to the second position, and the detection element 420 sends an electrical signal when detecting that the blocking rod 410 reaches the second position. Therefore, it can be determined whether there is a pin 200 in any positioning hole of the tray 100 by detecting the position of the blocking rod 410. The blocking rod 410 can effectively block the pin 200 in any positioning hole of the tray 100 from passing through the line body 300, preventing situations such as missed detection and misdetection. Compared with the prior art, the overall structure of the device is simple, the cost is low, and the detection efficiency is high.
[0037] Optionally, the pin insertion detection device 400 with an indefinite position further includes an alarm. After the blocking rod 410 is pushed by the pin 200, the detection element 420 transmits the signal to the control unit, and the control unit controls the alarm to give an alarm to remind the staff to remove the pin 200. Among them. The settings of the control unit and the alarm are prior art that is already mature and will not be elaborated here.
[0038] Furthermore, refer to Figure 3 and Figure 4, the connecting component 430 includes a guide post 432 and a guide sleeve 433. The guide sleeve 433 is connected to the wire body 300. The first end of the guide post 432 is connected to the blocking rod 410, and the second end of the guide post 432 is movably inserted through the guide sleeve 433 along the conveying direction of the wire body 300. It can be understood that the blocking rod 410 and the guide post 432 are vertically arranged. When the pin 200 pushes the blocking rod 410, the guide post 432 will move within the guide sleeve 433, and the guide sleeve 433 can guide the movement of the guide post 432 to ensure the smooth operation of the blocking rod 410.
[0039] Furthermore, the connecting component 430 further includes an elastic member 431 and a fixing member 434. The first end of the guide post 432 is connected to the blocking rod 410 through the fixing member 434. The elastic member 431 is sleeved on the guide post 432 and is located between the fixing member 434 and the guide sleeve 433. When the pin 200 pushes the blocking rod 410 to move, the fixing member 434 moves in the direction close to the guide sleeve 433. At the same time, the elastic member 431 contracts; when the pin 200 is taken away from the blocking rod 410, the elastic member 431 elongates and pushes the fixing member 434, thereby causing the blocking rod 410 to return to its original position. It can be understood that the setting of the elastic member 431 can enable the blocking rod 410 to automatically return to its original position without manual restoration, reducing the workload of the staff and effectively improving work efficiency. In addition, the setting of the elastic member 431 can prevent the pin 200 and the blocking rod 410 from making hard contact, effectively reducing the damage caused by the blocking rod 410 to the pin 200. Optionally, the elastic member 431 can be a compression spring.
[0040] Optionally, the fixing member 434 is a block structure. The position of the guide post 432 is higher than that of the blocking rod 410, that is, the first end of the guide post 432 is connected to the top of the fixing member 434, and the blocking rod 410 is located at the bottom of the fixing member 434.
[0041] Furthermore, the fixing member 434 is provided with a first fixing hole and a second fixing hole. The blocking rod 410 passes through the first fixing hole, and the first end of the guide post 432 passes through the second fixing hole. In this embodiment, a first locking portion is provided at the bottom of the fixing member 434. A first opening is formed in the middle of the first locking portion, and the first opening is communicated with the first fixing hole. A bolt passing through the first locking portion can lock the first opening, thereby fixing the blocking rod 410 in the first fixing hole. Similarly, a second locking portion is provided at the top of the fixing member 434. A second opening is formed in the middle of the second locking portion, and the second opening is communicated with the second fixing hole. A bolt passing through the second locking portion can lock the second opening, thereby fixing the guide post 432 in the second fixing hole. In other embodiments, the blocking rod 410 and the guide post 432 can be connected to the fixing member 434 by means of bolts, bonding or other connection methods.
[0042] Further, an anti - detachment portion 4321 is provided at the second end of the guide post 432. The anti - detachment portion 4321 can prevent the guide post 432 from disengaging from the guide sleeve 433. Optionally, the anti - detachment portion 4321 is a cylindrical structure, and its outer diameter is larger than the inner diameter of the guide sleeve 433, thereby being able to prevent the guide post 432 from disengaging from the guide sleeve 433. Of course, in other embodiments, the anti - detachment portion 4321 can also be a prismatic or other structural form, as long as it can prevent the guide post 432 from disengaging from the guide sleeve 433.
[0043] Further, at least one end of the blocking rod 410 is provided with a limiting member 440. The limiting member 440 is connected to the wire body 300. When the blocking rod 410 moves in the direction close to the guide sleeve 433, the limiting member 440 can abut against the blocking rod 410. By providing the limiting member 440 in the moving direction of the blocking rod 410 close to the guide sleeve 433, the moving distance of the blocking rod 410 can be limited. It can be understood that the position of the limiting member 440 can be set in cooperation with the detection range of the detection element 420 to avoid the moving distance of the blocking rod 410 towards the guide sleeve 433 being too large and thus exceeding the detection range of the detection element 420. In this embodiment, one limiting member 440 is provided. In other embodiments, the number of the limiting members 440 can be two, and the two limiting members 440 are respectively located at both ends of the blocking rod 410.
[0044] Further, the indefinite - position pin - inserting detection device 400 further includes a mounting bracket 460. The detection element 420 is connected to the wire body 300 through the mounting bracket 460. Optionally, the mounting bracket 460 is a block - shaped structure, and one end of the detection element 420 penetrates through the mounting bracket 460. In this embodiment, the number of the mounting brackets 460 is one, and they are respectively located at both ends of the blocking rod 410 together with the limiting member 440. In other embodiments, the number of the mounting brackets 460 can also be two, and the two mounting brackets 460 are respectively located at both ends of the blocking rod 410, and one detection element 420 is provided on each mounting bracket 460.
[0045] Further, the indefinite - position pin - inserting detection device 400 further includes a protective cover 450. The protective cover 450 is connected to the wire body 300 to form a receiving cavity that at least accommodates the detection element 420. The setting of the protective cover 450 plays a protective role for the detection element 420, effectively extending the service life of the detection element 420 and ensuring the normal operation of the indefinite - position pin - inserting detection device 400.
[0046] Further, the detection component 420 can be a proximity sensor. When the blocking rod 410 enters the sensing area of the proximity sensor, the proximity sensor can accurately reflect the position and stroke of the blocking rod 410, and can make the switch act without mechanical contact or applying any pressure, providing a control instruction for the control unit. The proximity sensor has the advantages of reliable operation, stable performance, fast frequency response, strong anti-interference ability, and long service life.
[0047] This embodiment also provides a motor assembly production line, including a line body 300, a tray 100, and the above-mentioned indefinite-position pin detection device 400.
[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
