Description

Technical Field

[0001] This utility model relates to the field of stator and pin assembly, and more particularly to a stator pin insertion mechanism. Background Technology

[0002] Stator pins refer to the metal pins inserted into the stator frame.

[0003] There are many types of pins after they leave the factory, including pins that are in the form of material strips. These pins need to be separated from the edge material. At the same time, the pins and the frame are interference fit, and strong pressing force is required to assemble the pins and the frame.

[0004] The current equipment for assembling pins and the frame separates the pins from the strip by stamping. Specifically, the pins in the vertical strip are arranged longitudinally. In this setting, the pins are punched out from top to bottom. However, this equipment lacks control over the pin assembly force and height, which often results in the pins being crooked or having inconsistent heights between them. Utility Model Content

[0005] To solve the above problems, this utility model provides a stator pin insertion mechanism to solve the assembly process problem between the strip-type pins and the frame.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a stator pin insertion mechanism, characterized in that it comprises:

[0007] The cutting mechanism includes a pressure pin with an adaptation pin outer edge, a moving component and a sensor for performing linear motion. The sensor includes a displacement sensor and a pressure sensor. The trigger end of the displacement sensor is located in the moving path of the moving component. The displacement sensor, pressure sensor and pressure pin are disposed on the first moving component. The trigger end of the displacement sensor is located in the moving path of the first moving component. The detection end of the pressure sensor is connected to another second moving component driven by a power source.

[0008] The channel is used to guide the material strip to move in a specific direction. The channel has a branch that connects to the interior. This branch allows the pressure needle to pass through, and the end of the pressure needle serves as the pressure foot to cut off the edge material.

[0009] The beneficial effects of this utility model are:

[0010] This utility model provides a specific cutting mechanism that can not only handle the material strip type pins fed in the channel, but also perform bidirectional measurement on the assembly between the pins and the frame. For example, by using displacement sensors and pressure sensors, the height of the pins and the tightness of the pins in the frame can be controlled respectively. Of course, by using pressure sensors, the pins can also be prevented from bending due to excessive pressure.

[0011] In this invention, the pressure sensor is a tension / compression sensor. Its sensing end is an elastic body composed of a resistance strain gauge, used to directly sense external force and convert it into an electrical signal. The other moving component is the elastic body that acts directly within the tension / compression sensor. The deformation of the elastic body changes the cross-sectional area of ​​the resistance strain gauge, thereby measuring the current pressure value. Tension / compression sensors are existing technology, and their principle will not be elaborated further.

[0012] Each moving component includes a slider and a fixed block. The two ends of the fixed block are respectively set on the two sliders. The fixed block of the second moving component has an arched docking part, which is connected to the detection end of the pressure sensor. The docking part is adapted to the spatial dimensional relationship between the pressure sensor and the detection end after the pressure sensor is set after the first moving component.

[0013] The displacement sensor includes a contact block and a sensing part with a contact head. The sensing part is disposed on the first moving component, while the contact block is disposed on the frame and located in the moving path of the first moving component. The contact block and the contact head correspond to each other.

[0014] In this embodiment, a frame is also included, and a first slide rail is provided on the side of the frame. The first slide rail and the slider are slidably connected, and the entire cutting action is performed longitudinally.

[0015] Above the frame, there is a motor that serves as a power source. The motor shaft is equipped with a screw, which is threadedly connected to the fixing block of the second moving component. Under the action of the motor, the second moving component moves longitudinally on the frame and also moves up and down by the pressure sensor, either by pulling or pushing the first moving component.

[0016] The interlocking pin guide block and the cutting guide block form part of the channel. The pin guide block is set on the frame and has a groove on its surface. When the cutting guide block is assembled with the pin guide block, a channel is formed between the groove and the cutting guide block. The groove also extends to form a branch for the pin presser to pass through, as well as an outlet for the pin to be pushed out of the channel after it is broken.

[0017] The other part of the channel is the feeding mechanism, which includes a feed channel and a cover plate, with the cover plate covering the slot structure on the feed channel.

[0018] Since the strip is made of metal and the channel has a certain length, a feeding mechanism is needed to prevent the strip from getting stuck in the channel. This mechanism will drag the strip through the channel.

[0019] Considering the impact on the overall size and workflow, the feeding mechanism was installed on the feed channel using the following structure:

[0020] The feed channel includes a feed cylinder, a slide block, a lever, and a spring. A second slide rail is located on the back of the feed channel. The slide block is slidably connected to the second slide rail via a second slider. A cylinder mounting seat is also located on the back of the feed channel, and the feed cylinder is mounted on the cylinder mounting seat. The piston rod of the feed cylinder is connected to the slide block. The slide block is slidably assembled with the second slide rail after being fitted onto the feed channel. The slide block has a receiving groove, and the spring and lever are housed within the receiving groove. One end of the lever has a locking structure, which is triangular in shape. The material strip is pulled against the inner wall of the slot structure by the elastic force of the spring (the cover plate has a strip groove, and the locking structure enters the slot structure through the strip groove). At the same time, after the locking structure passes through the gap between the pins, a fulcrum is formed on the material strip to be dragged. During the dragging process, the right-angle side of the locking structure is against the pin and pushes the material strip forward. The inclined surface of the locking structure faces the pin behind. When the lever is reset, the inclined surface provides a guiding effect for the reverse movement. Moreover, this guidance allows the lever to achieve the purpose of avoidance by compressing the spring.

[0021] In other words, the spring and the lever are set in the receiving groove, the locking structure passes through the strip groove under the elastic force of the spring, and the locking structure also abuts against the inner wall of the groove structure.

[0022] It should be noted that the spring is located near the end of the lever with the locking structure.

[0023] Because of the use of springs, the locking structure can be retracted by compressing the springs. However, occasionally the locking structure gets stuck with the pin, causing the entire conveyor belt to move in the opposite direction. To solve this problem, multiple slide block fixing blocks, lever blocks, and springs are provided. At most one slide block fixing block is connected to the piston rod of the feed cylinder. Since the other slide block fixing blocks are not connected to the feed cylinder, the position of the lever blocks in this part remains unchanged, resisting the conveyor belt to retract.

[0024] The outer surface of the cutting guide block is provided with a detection hole, which is connected to the channel and also includes an optical fiber sensor. The optical fiber sensor is set on the cutting guide block, and the detection end of the optical fiber sensor corresponds to the detection hole. Attached Figure Description

[0036] like Figure 1-11 As shown, a stator pin insertion mechanism is characterized by comprising:

[0037] The cutting mechanism 1 includes a pressure needle 100 with an adapter pin 51 on the outer edge, a moving component and a sensor for performing linear motion. The sensor includes a displacement sensor 3 and a pressure sensor 4. The trigger end of the displacement sensor 3 is located in the moving path of the moving component. The displacement sensor 3, the pressure sensor 4 and the pressure needle 100 are disposed on the first moving component 102. The trigger end of the displacement sensor 3 is located in the moving path of the first moving component 102. The detection end of the pressure sensor 4 is connected to the moving end of another second moving component 103 driven by a power source.

[0038] The channel is used to guide the material belt 5 to move in a specific direction. A branch is reserved in the channel to communicate with the interior. The branch is for the pressure needle 100 to pass through, and the end of the pressure needle 100 serves as the pressure foot for breaking the edge material 52.

[0039] The beneficial effects of this utility model are:

[0040] This utility model provides a specific cutting mechanism 1, which can not only handle the material strip 5 type pin 51 fed in the channel, but also perform a bidirectional measurement on the assembly between the pin 51 and the frame 6. For example, by using the displacement sensor 3 and the pressure sensor 4, the height of the pin 51 and the tightness of the pin 51 in the frame 6 can be controlled respectively. Of course, by using the pressure sensor 4, the pin 51 can also be prevented from bending due to overpressure.

[0041] In this invention, the pressure sensor 4 is a tension / compression sensor. Its sensing end is an elastic body composed of a resistance strain gauge, used to directly sense external force and convert it into an electrical signal. The other moving component is the elastic body that acts directly within the tension / compression sensor. The deformation of the elastic body changes the cross-sectional area of ​​the resistance strain gauge, thereby measuring the current pressure value. Tension / compression sensors are existing technology, and their principle will not be elaborated further.

[0042] Each moving component includes a slider 1000 and a fixed block 1001. The two ends of the fixed block 1001 are respectively disposed on the two sliders 1000. The fixed block 1001 of the second moving component 103 has an arched docking part 1002. The docking part 1002 is connected to the detection end of the pressure sensor 4. The docking part 1002 is adapted to the spatial dimensional relationship between the pressure sensor 4 and the detection end after the pressure sensor 4 is disposed on the first moving component 102.

[0043] The displacement sensor 3 includes a contact block 31 and a sensing part with a contact head 32. The sensing part is disposed on the first moving component 102, while the contact block 31 is located in the moving path of the first moving component 102. The contact block 31 and the contact head 32 correspond to each other.

[0044] In this embodiment, a frame 7 is also included, and a first slide rail is provided on the side of the frame 7. The entire cutting action is carried out longitudinally.

[0045] Above the frame 7, there is a motor 81 that serves as a power source. The motor shaft of the motor 81 is equipped with a screw 82, which is threadedly connected to the fixing block 1001 of the second moving component 103. Under the action of the motor 81, the second moving component 103 moves longitudinally on the frame 7, and also moves up and down by the pressure sensor 4, which carries or pushes the first moving component 102.

[0046] The interlocking pin guide block 10 and the cutting guide block 11 form part of the channel. The pin guide block 10 is set on the frame 7. The surface of the pin guide block 10 is provided with a groove 10a. When the cutting guide block 11 is assembled with the pin guide block 10, a channel is formed between the groove 10a and the cutting guide block 11. The groove 10a also extends to form a branch through which the pressure pin 100 passes, and an outlet from which the pin 51 is pushed out of the channel after being disconnected.

[0047] Another part of the channel is the feeding mechanism, which includes a feed channel 91 and a cover plate 92. The cover plate 92 covers the slot structure 91a of the feed channel 91.

[0048] Since the strip 5 is made of metal and the channel has a certain length, a feeding mechanism is needed to prevent the strip 5 from getting stuck in the channel. This mechanism will drag the strip 5 in the channel.

[0049] Considering the impact on the overall size and workflow, the feeding mechanism was installed on the feed channel 91 using the following structure:

[0050] The feed channel 91 includes a feed cylinder 93, a slide block 94, a lever 95, and a spring 96. A second slide rail 91b is provided on the back of the feed channel 91. The slide block 94 is slidably connected to the second slide rail 91b via a second slider 97. A cylinder mounting seat 98 is also provided on the back of the feed channel 91, and the feed cylinder 93 is mounted on the cylinder mounting seat 98. The piston rod of the feed cylinder 93 is connected to the slide block 94. The slide block 94 is slidably assembled with the second slide rail 91b after being fitted onto the feed channel 91. The slide block 94 has a receiving groove 94a, and the spring 96 and lever 95 are located within the receiving groove 94a. One end of the lever 95 has a locking structure 95a, which is a three-position locking structure. The angled locking structure 95a is abutted against the inner wall of the slot structure 91a by the elastic force of the spring 96 (the cover plate 92 is provided with a strip groove 92a, through which the locking structure 95a enters the slot structure 91a). At the same time, after the locking structure 95a passes through the gap between the pins 51, a dragging fulcrum is formed on the material strip 5. During the dragging process, the right-angled side of the locking structure 95a abuts against the pin 51 and pushes the material strip 5 forward. The inclined surface of the locking structure 95a faces the rear pin 51. When the lever 95 is reset, the inclined surface provides a guiding effect for the reverse movement. Furthermore, this guidance allows the lever 95 to achieve the purpose of avoidance by compressing the spring 96.

[0051] It should be noted that the spring 96 is located near the end of the lever 95 that has the locking structure 95a.

[0052] Because of the use of spring 96, the locking structure 95a can be retracted by compressing spring 96. However, occasionally the locking structure 95a gets stuck with pin 51, causing the entire conveyor belt 5 to move in the opposite direction. To solve this problem, an additional slide block 94, a lever block 95, and spring 96 are added. Since the new slide block 94 is not connected to the feed cylinder 93, the position of the new lever block 95 remains unchanged, pressing against the conveyor belt 5 and retracting it.

[0053] The outer surface of the cutting guide block 11 is provided with a detection hole, which is connected to the channel and also includes an optical fiber sensor 12. The optical fiber sensor 12 is set on the cutting guide block 11, and the detection end of the optical fiber sensor 12 corresponds to the detection hole. It is used to detect whether there is a pin 51 below the pressure needle component 100. Based on this information, the host computer decides whether to continue to execute the operation of the pressure needle component 100.

[0054] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
