Description

Technical Field

[0001] This application belongs to the technical field of motor production, and particularly relates to a motor stator electrical terminal press-fitting machine and a press-fitting method. Background Art

[0002] As a special type of motor, the chain motor has unique features in the design and structure of the stator core. The stator core of the chain motor usually consists of a series of ring-shaped or chain-shaped cores, which are precisely connected together to form a closed ring structure. The main function of this structure is to provide a magnetic circuit and fix the stator coil to ensure the efficient and stable operation of the motor. Each core maintains a high degree of consistency in shape and size to ensure the overall performance and quality of the motor.

[0003] In the current production process, after the core is inserted into the chain plate fixture, the overall forms a chain plate fixture assembly. Then, operations such as winding copper wires, circular welding, wire arranging, wire cutting, and paint stripping need to be carried out on the product. After the above processes, electrical terminals (such as grounding terminals and fish-eye terminals) also need to be press-fitted onto the stator. Currently, the press-fitting of electrical terminals relies on manual operation. However, this method not only has low production efficiency and is difficult to meet the needs of large-scale production, but also due to the different proficiency and skill levels of workers, the quality of the produced motors varies, making it difficult to ensure the consistency and stability of the motor quality. Summary of the Invention

[0031] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application; the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; in addition, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0033] Referring to Figure 1 and Figure 2 , there is shown a motor stator electrical terminal press-fitting machine provided by this embodiment, including a press-fit ground terminal mechanism 10, a vision detection system 20, a press-fit fish-eye terminal mechanism 30, an alarm system, and a defective product storage box 40 for storing unqualified products.

[0034] Referring together to Figure 3 and Figure 4, the press grounding terminal mechanism 10 includes a grounding terminal installation fixture 11, a press grounding terminal lifting plate 12, a grounding terminal downward pressing driving member 13, a first stator fixing fixture 14, a press grounding terminal limiting post 15, a press grounding terminal displacement sensor 16, a first product detection sensor 17, a first bottom plate 18, a press grounding terminal lifting slide rod 19, a press grounding terminal lifting slide sleeve 1a, and a first restoring spring 1b.

[0035] The grounding terminal installation fixture 11 fixes the grounding terminal through true pressure adsorption, and the grounding terminal downward pressing driving member 13 can drive the press grounding terminal lifting plate 12 and the grounding terminal installation fixture 11 to press downward together. The first stator fixing fixture 14 is located directly below the grounding terminal installation fixture 11. When the grounding terminal installation fixture 11 is pressed down to the set height, the grounding terminal thereon can just be pressed into the slot of the stator.

[0036] The press grounding terminal limiting post 15 is used to limit the lowest position of the press grounding terminal lifting plate 12. The press grounding terminal limiting post 15 is arranged below the press grounding terminal lifting plate 12 and is located on the outer side of the first stator fixing fixture 14. The top surface of the press grounding terminal limiting post 15 is higher than the top surface of the first stator fixing fixture 14. By arranging the press grounding terminal limiting post 15, it can prevent the machine from accidentally damaging the product.

[0037] The installation position of the press grounding terminal displacement sensor 16 is higher than the top surface of the press grounding terminal limiting post 15. The displacement data of the press grounding terminal displacement sensor 16 being pressed down is transmitted to the host computer. The host computer judges the downward pressing depth of the press grounding terminal lifting plate 12 according to the displacement data, and then judges whether the grounding terminal is pressed in place. When it is detected that it is not pressed in place, the host computer controls the alarm system to send out an alarm signal to inform the staff.

[0038] The first product detection sensor 17 is a transmissive photoelectric sensor. The transmitting end and the receiving end of the first product detection sensor 17 are respectively located on the opposite sides of the first stator fixing fixture 14. The light emitting direction of its transmitting end faces the position where the product is placed directly above the first stator fixing fixture 14. When there is no product on the first stator fixing fixture 17, the first product detection sensor 17 is triggered to send a signal to the host computer, and the host computer controls the alarm system to send out an alarm signal to inform the staff.

[0039] The pressing grounding terminal lifting slide rod 19 is vertically fixed on the first base plate 18. The pressing grounding terminal lifting sleeve 1a is slidably sleeved on the periphery of the pressing grounding terminal lifting slide rod 19. The pressing grounding terminal lifting sleeve 1a is fixedly connected to the pressing grounding terminal lifting plate 12. The first restoring spring 1b is sleeved on the periphery of the pressing grounding terminal lifting slide rod 19 and is clamped between the pressing grounding terminal lifting plate 12 and the first base plate 18. Since there is no fixed connection between the grounding terminal pressing driving member 13 and the pressing grounding terminal lifting plate 12, the pressing driving member 13 only exerts a pressing force on the pressing grounding terminal lifting plate 12 and has no lifting effect. Therefore, in this embodiment, the first restoring spring 1b can lift the pressing grounding terminal lifting plate 12 to its original position.

[0040] Refer again to Figure 1 and Figure 2 , the shooting direction of the vision detection system 20 faces the stator installed on the first stator fixing jig 14, and is used to collect the reference marks on the stator and feedback them to the host computer. The host computer judges whether the installation orientation of the stator is correct according to the received image information. When the installation orientation of the stator is incorrect, the host computer controls the alarm system to send out an alarm signal. By setting the vision detection system 20, the feeding angle of the stator can be automatically identified to avoid positioning errors during subsequent pressing of electrical terminals.

[0041] Refer to together Figure 5 and Figure 6 , the fish-eye terminal mechanism 30 includes a fish-eye terminal installation jig 31, a fish-eye terminal pressing lifting plate 32, a fish-eye terminal pressing driving member 33, a second stator fixing jig 34, a fish-eye terminal pressing limiting post 35, a second product detection sensor 36, a fish-eye terminal detection sensor 37, a second base plate 38, a fish-eye terminal pressing lifting slide rod 39, a fish-eye terminal pressing lifting sleeve 3a, and a second restoring spring 3b.

[0042] The fish-eye terminal installation jig 31 fixes the fish-eye terminal by vacuum adsorption. The fish-eye terminal pressing driving member 33 can drive the fish-eye terminal pressing lifting plate 32 and the fish-eye terminal installation jig 31 to lift and lower together. The second stator fixing jig 34 is located directly below the fish-eye terminal installation jig 31. When the fish-eye terminal installation jig 31 is pressed down to the set height, the fish-eye terminal on it can just be pressed into the slot of the stator.

[0043] The fish-eye terminal pressing limiting post 35 is used to limit the lowest position of the fish-eye terminal pressing lifting plate 32. The fish-eye terminal pressing limiting post 35 is arranged below the fish-eye terminal pressing lifting plate 32 and is located on the outer side of the second stator fixing jig 34. The top surface of the fish-eye terminal pressing limiting post 35 is higher than the top surface of the second stator fixing jig 34. By setting the fish-eye terminal pressing limiting post 35, the machine can be prevented from accidentally damaging the product.

[0044] The second product detection sensor 36 and the fish-eye terminal detection sensor 37 are both opposed type photoelectric sensors. The transmitting end and the receiving end of the second product detection sensor 36 are respectively located on the opposite sides of the second stator fixing fixture 34. When there is no product on the second stator fixing fixture 34, the second product detection sensor 36 is triggered to send a signal to the host computer, and the host computer controls the alarm system to send an alarm signal to inform the staff. Similarly, the fish-eye terminal detection sensor 37 emits a signal to the top surface position of the fish-eye terminal (the height of this position can be obtained by measurement when the fish-eye terminal is pressed and installed qualified) to detect whether the fish-eye terminal is pressed in place. When the light emitted by its transmitting end is blocked, it means that it has not been pressed down in place. When an abnormality is detected, the staff is also informed through the alarm system. In actual operation, a certain range of error in the pressing height should be allowed. Therefore, in this embodiment, the connection line between the transmitting end and the receiving end of the fish-eye terminal detection sensor 37 is inclined at a certain angle to the horizontal plane, so that the emitted light is inclined to the horizontal plane, and the path of the light propagates within a certain height range. If the fish-eye terminal enters this height range, it means that the pressing height is not enough and it has not been pressed in place.

[0045] The fish-eye terminal pressing lifting slide bar 39 is vertically fixed on the second bottom plate 38. The fish-eye terminal pressing lifting slide sleeve 3a is slidably sleeved on the periphery of the fish-eye terminal pressing lifting slide bar 39. The fish-eye terminal pressing lifting slide sleeve 3a is fixedly connected to the fish-eye terminal pressing lifting plate 32. The second return spring 3b is sleeved on the periphery of the fish-eye terminal pressing lifting slide bar 39 and is clamped between the fish-eye terminal pressing lifting plate 32 and the second bottom plate 38. Since the fish-eye terminal pressing driving member 33 is not fixedly connected to the fish-eye terminal pressing lifting plate 32, the fish-eye terminal pressing driving member 33 only exerts a pressing force on the fish-eye terminal pressing lifting plate 32 and has no lifting effect. Therefore, in this embodiment, the second return spring 3b can make the fish-eye terminal pressing lifting plate 32 rise to its original position.

[0046] The defective product storage box 40 is provided with an intelligent box door. Each time the alarm system alarms, the intelligent box door is correspondingly opened once. When the intelligent box door is not opened, it means that defective products are mixed in the qualified products, and the alarm system informs the user through a sound or light signal.

[0047] To make the working principle and working process of the motor stator electrical terminal press in this embodiment clearer, this embodiment also provides the pressing method for the above-mentioned motor stator electrical terminals, including the following steps:

[0048] Manually load the grounding terminal into the grounding terminal installation fixture 11. The grounding terminal installation fixture 11 adsorbs the grounding terminal through negative pressure, and feed the stator to the first stator fixing fixture 14. The first stator fixing fixture 14 fixes the stator.

[0049] The visual detection system 40 automatically collects the image information of the stator and feeds it back to the host computer. The host computer determines whether the feeding angle of the stator is correct. When it is incorrect, the alarm system sends an alarm signal to the user to inform the staff to place the product in the correct position or directly remove the product temporarily;

[0050] After determining that the feeding angle of the stator is correct, the grounding terminal pressing driver 13 works to drive the grounding terminal installation fixture 11 and the grounding terminal to press in place, that is, the grounding terminal pressing operation is completed;

[0051] Manually transfer the stator to the second stator fixing fixture 34, and the second stator fixing fixture 34 fixes the stator; feed the fish-eye terminal to the fish-eye terminal installation fixture 31, and the fish-eye terminal installation fixture 31 adsorbs and fixes the fish-eye terminal by generating negative pressure;

[0052] The visual detection system 40 automatically collects the image information of the stator and feeds it back to the host computer. The host computer determines whether the feeding angle of the stator is correct. When it is incorrect, the alarm system sends an alarm signal to inform the staff to place the product in the correct position or directly remove the product temporarily;;

[0053] After determining that the feeding angle of the stator is correct, the fish-eye terminal pressing driver 33 works to drive the fish-eye terminal installation fixture 31 and the grounding terminal to press in place, that is, the fish-eye terminal pressing operation is completed.

[0054] In summary, this embodiment realizes the automatic recognition of the feeding angle of the stator, the automatic pressing of electrical terminals, and the automatic detection of the pressing depth. Moreover, when an error occurs in a certain link, the alarm system can send an alarm signal to the user in real time. It can be seen that this embodiment realizes the mechanization and automation of the electrical terminal pressing. Compared with the current production method of manually pressing electrical terminals, this embodiment improves the production efficiency of the motor, saves labor costs, and at the same time ensures the consistency and stability of the motor quality.

[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
