The device comprises multiple support columns, with screws mounted on the upper surfaces of opposite sides of each group of support columns for common rotation. A first motor is mounted on the front surface of each front support column, and two threaded blocks are mounted on the rod walls of each screw. The device utilizes two limit springs within an opening to clamp the coil to be tinned. The two threaded rods rotate, driving the mold and coil downward for tinning.

[0046] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] The following is combined with Figure 1-8 The transplanting, turning and tinning device 400 and the wire twisting and tinning integrated module 500 for the hollow cup motor coil production line of the present invention are further described.

[0048] Please focus on Figure 2-4The utility model discloses a transplanting and turning tinning device 400, comprising a fixed mounting frame 100 and a transplanting and turning tinning unit 200 mounted on the fixed mounting frame 100; the transplanting and turning tinning unit 200 comprises: a coil flexible clamping component 2, a tinning rotary drive 1 for driving the coil flexible clamping component 2 to rotate, a tinning lifting cylinder 3 connected to the tinning rotary drive 1 and used to drive the tinning rotary drive 1 and the coil flexible clamping component 2 to extend and retract as a whole; the coil flexible clamping component 2 comprises: a tinning two-finger pneumatic telescopic clamping jaw 21, a first adapter clamping jaw 22, a second adapter clamping jaw 23, a first clamping part 24, and a second clamping part 25; the tinning two-finger pneumatic telescopic clamping jaw 21 comprises: a tinning clamping jaw housing 211, a second adapter clamping jaw 22, a second adapter clamping jaw 23, a first clamping part 24, and a second clamping part 25. A tinning clamp finger 212 and a second tinning clamp finger 213; the tinning clamp housing 211 is connected to the tinning rotary drive 1; one end of the first adapter clamp 22 is fixedly connected to the first tinning clamp finger 212, and the other end of the first adapter clamp 22 is slidingly connected to the first clamping part 24, and a first compression spring 26 is provided between the first adapter clamp 22 and the first clamping part 24; one end of the second adapter clamp 23 is fixedly connected to the second tinning clamp finger 213, and the other end of the second adapter clamp 23 is slidingly connected to the second clamping part 25, and a second compression spring 27 is provided between the second adapter clamp 23 and the second clamping part 25; the first clamping part 24 and the second clamping part 25 together form a clamping cavity 28 that matches the shape of the coil to be tinned.

[0049] In this embodiment, the immersion tin rotary drive 1 is used to provide rotational power, and the immersion tin rotary drive 1 can be a rotary motor, a rotary cylinder or a rotary pump.

[0050] The two-finger pneumatic retractable tin-immersing clamp 21 is an existing product that can be directly purchased from outside. Under the drive of a pressure air source, the first tin-immersing clamp finger 212 and the second tin-immersing clamp finger 213 can be opened and closed.

[0051] The adapter jaws (the first adapter jaw 22 and the second adapter jaw 23 ) are used to connect the clamping fingers (the first immersion tin clamping fingers 212 and the second immersion tin clamping fingers 213 ) and the clamping parts (the first clamping part 24 and the second clamping part 25 ).

[0052] The first clamping part 24 and the second clamping part 25 are in direct contact with the coil to be tinned. Since the first clamping part 24 is slidably connected to the first adapter clamping jaw 22, and a first compression spring 26 is provided between the two, and the second clamping part 25 is slidably connected to the second adapter clamping jaw 23, and a second compression spring 27 is provided between the two, therefore, when the first clamping part 24 and the second clamping part 25 clamp the coil to be tinned, the compression spring is forced to contract, thereby realizing flexible clamping of the coil to be tinned. By reasonably setting the performance of the compression spring, the coil to be tinned can be prevented from being clamped and deformed.

[0053] During use, the rotation angle of the tinning rotary drive 1 can be reasonably determined based on the specific layout of the hollow cup motor coil automatic production line (such as the position of the coil to be tinned, the direction of the wire end to be tinned, and the position of the tin bath). For example, if the coil to be tinned is located on the left side of the tinning rotary drive 1 and is placed horizontally, the wire end to be tinned faces right, and the tin bath is placed on the right side of the tinning rotary drive 1 with the notch facing upward. The rotation angle of the tinning rotary drive 1 is determined to be 90°. The initial angle is just enough to clamp the coil to be tinned that is placed horizontally and has the wire end to be tinned facing right. After rotating 90°, the coil to be tinned will be adjusted to a vertical position with the wire end to be tinned facing downward. If the coil to be tinned is located on the left side of the tinning rotary drive 1 and is placed vertically, the wire end to be tinned faces upward, and the tin bath is placed on the right side of the tinning rotary drive 1 with the notch facing upward. The rotation angle of the tinning rotary drive 1 is determined to be 180 degrees. The initial angle is just used to clamp the vertically placed tinned coil with the tinned wire head facing upwards. After rotating 180 degrees, the tinned coil will be adjusted to a vertical position with the tinned wire head facing downwards. It should be noted that in this paragraph, the reference Figure 2 , the direction "left" refers to the positive direction of the X-axis, the direction "right" refers to the negative direction of the X-axis, the direction "up" refers to the positive direction of the Y-axis, and the direction "down" refers to the negative direction of the Y-axis.

[0054] Assume that in the transplanting and flipping tinning device 400 of the present invention, the initial position is: the tinning lifting cylinder 3 is in the upward retracted state of the loading position, and the coil flexible clamping component 2 is located on the left side of the tinning rotary drive 1.

[0055] Loading process: The tinning lift cylinder 3 extends downward and gradually approaches the coil to be tinned. The two-finger pneumatic telescopic clamp 21 opens. When the first and second clamps 24 and 25 descend to the sides of the coil to be tinned, the tinning lift cylinder 3 stops and the two-finger pneumatic telescopic clamp 21 closes. As the first and second clamps 24 and 25 clamp the coil to be tinned, the compression spring contracts under force, achieving flexible clamping of the coil to be tinned, thus preventing the coil from being flattened.

[0056] Tinning process: The tinning lifting cylinder 3 is retracted upward, and at the same time, the clamped coil to be tinned is moved upward. When it reaches the preset height, the tinning rotary drive 1 rotates a preset angle (such as the aforementioned 90° or 180°), so that the coil to be tinned is adjusted to a vertical setting with the wire end to be tinned facing downward; the tinning lifting cylinder 3 extends downward and gradually approaches the tin tank until the wire end to be tinned is inserted into the tin liquid in the tin tank and the tinning is completed, and the tinning lifting cylinder 3 is retracted upward.

[0057] Unloading Process: After the unloading position is preset, the entire transfer and flipping tinning device 400 of the present invention can be moved to the unloading position via an external structure. Alternatively, the combined action of the tinning lift cylinder 3 and the tinning rotary drive 1 can be used to move the tinned coil, which has been tinned and is gripped by the two-finger pneumatic telescopic clamp 21, to the unloading position. Upon reaching the unloading position, the two-finger pneumatic telescopic clamp 21 opens, and the tinned coil falls to the unloading position.

[0058] The tin-immersion lifting cylinder 3 is returned to the initial position and the above-mentioned action is repeated to realize the automatic continuous unloading of the hollow quilt motor coil.

[0059] It should be noted that how to achieve continuous feeding of the coils to be tinned and how to ensure the position of the coils to be tinned are not technical problems to be solved by the present invention and will not be elaborated here, which will not affect the full disclosure of the present invention.

[0060] The transplanting, turning and tinning device 400 of the present invention is based on the existing mature two-finger pneumatic telescopic clamp and rotation angle control technology, which improves the automation and flexibility of the equipment.

[0061] Compared with the prior art, the transplanting and flipping tinning device 400 of the present invention is adopted, and the coil flexible clamping component 2 is used to clamp the coil to be tinned for loading and unloading, thereby avoiding the manual loading method of squeezing the motor coils into the clamping block one by one, avoiding the deformation of the motor coil during loading, and at the same time improving the degree of automation of loading. The transplanting and flipping tinning device 400 of the present invention is also adopted, and the unloading method of directly pushing the coil out with a pushing block is avoided, which greatly avoids the deformation of the motor coil during the unloading process.

[0062] According to a specific embodiment of the present utility model, the first clamping portion 24 includes: a first spring pressure plate 241, a first coil profiling chuck 242 and a first guide screw 243; the two ends of the first guide screw 243 are respectively connected to one end of the first adapter jaw 22 and the first spring pressure plate 241, and the other end of the first adapter jaw 22 is connected to the first immersion tin finger 212; the first spring pressure plate 241 is slidably connected to the first guide screw 243, and the first compression spring 26 is sleeved on the first guide screw 243, and the two ends of the first compression spring 26 respectively abut the first adapter jaw 22 and the first spring pressure plate 241, the first coil profiling chuck 242 is detachably mounted on the side of the first spring pressure plate 241 away from the first adapter jaw 22, and the first coil profiling chuck 242 is provided with a concave first profiling half groove 2421 on the side away from the first coil profiling chuck 242; the second clamping portion 25 includes In summary: a second spring pressure plate 251, a second coil profiling chuck 252 and a second guide screw 253; two ends of the second guide screw 253 are respectively connected to one end of the second adapter jaw 23 and the second spring pressure plate 251, and the other end of the second adapter jaw 23 is connected to the second immersion tin finger 213; the second spring pressure plate 251 is slidably connected to the second guide screw 253, and the second compression spring 27 is sleeved on the second guide screw 253, and the two ends of the second compression spring 27 respectively abut the second adapter jaw 23 and the second spring pressure plate 251, the second coil profiling chuck 252 is detachably mounted on the side of the second spring pressure plate 251 away from the second adapter jaw 23, and the second coil profiling chuck 252 is provided with a recessed second profiling half groove 2521 on the side away from the second coil profiling chuck 252; the first profiling half groove 2421 and the second profiling half groove 2521 together form a clamping cavity 28.

[0063] The first coil profiling clamp 242 of the coil flexible clamping assembly 2 of this embodiment is slidably connected to the first adapter clamp 22 via the first compression spring 26. The second coil profiling clamp 252 is slidably connected to the second adapter clamp 23 via the second compression spring 27, thereby achieving flexible clamping and preventing the motor coil from being crushed.

[0064] The first coil profiling chuck 242 and the second coil profiling chuck 252 are both detachable structures, and different profiling chucks can be replaced according to the shapes of different motor coils. Different profiling chucks can form clamping cavities of different shapes and be made of materials of different hardness, which greatly improves the flexibility of use and expands the scope of use.

[0065] According to a specific embodiment of the present invention, the first clamping portion 24 and the second clamping portion 25 are symmetrical structures.

[0066] In this embodiment, the structure is adopted to facilitate symmetrical clamping and reduce processing and assembly costs.

[0067] According to the specific embodiment of the present invention, the coil flexible clamping assembly 2 also includes an opening limit assembly 29, and the opening limit assembly 29 includes: a limit column 291, an adjusting nut 292 and an axial screw 293, one end of the limit column 291 is inserted into the first adapter jaw 22 and the two are fixedly connected by the axial screw 293; the other end of the limit column 291 passes through the second adapter jaw 23, the adjusting nut 292 is sleeved on the limit column 291, and the adjusting nut 292 is threadedly connected to the limit column 291, and the adjusting nut 292 is located on the side of the second adapter jaw 23 away from the first adapter jaw 22.

[0068] In this embodiment, the opening limiter assembly 29 is used to mechanically limit the opening travel of the first and second adapter jaws 22, 23. Specifically, the second adapter jaw 23 is slidably connected to a limiter post 291, and an adjustment nut 292 limits the second adapter jaw 23. In practice, the opening travel can be adjusted by adjusting the threaded connection between the adjustment nut 292 and the limiter post 291. The use of the opening limiter assembly 29 effectively prevents the first and second adapter jaws 22, 23 from accidentally over-opening and striking surrounding components (such as the cylinder connector 4), thereby improving safety.

[0069] According to a specific embodiment of the present invention, the first coil profiling clamp 242 and the second coil profiling clamp 252 are both made of plastic.

[0070] In this embodiment, the structural components of the transfer and flip tinning device 400 are primarily made of metal. Since both the first coil profiling chuck 242 and the second coil profiling chuck 252 need to directly contact the motor coil, using softer plastic can prevent the coil profiling chucks from scratching the motor coil.

[0071] According to the specific embodiment of the present utility model, the tin immersion rotary drive 1 is a pneumatic rotary cylinder; a cylinder connector 4 is also provided between the tin immersion rotary drive 1 and the coil flexible clamping assembly 2; the cylinder connector 4 includes a connecting disk 41 and a connecting column 42 fixed to one side of the connecting disk 41, the connecting disk 41 is fixedly connected to the tin immersion rotary drive 1, and the tin immersion clamp housing 211 is fixedly installed on one side of the tin immersion clamp housing 211.

[0072] More specifically, two housing mounting holes are provided on one side of the immersion tin gripper housing 211. Connecting posts 42 are positioned opposite these mounting holes, and threaded connectors securely connect the immersion tin gripper housing 211 to the connecting posts 42. The connecting plate 41 is generally cylindrical, and the connecting posts 42 are also generally cylindrical, with a diameter smaller than that of the connecting plate 41.

[0073] In this embodiment, the cylinder connector 4 is used to connect the tinning rotary drive 1 and the coil flexible clamping assembly 2, which improves assembly convenience. The connecting plate 41 matches the shape of the connecting structure of the tinning rotary drive 1, and the connecting column 42 matches the connecting structure of the tinning clamp housing 211, avoiding redundant physical structure.

[0074] The diameter of the connecting column 42 is smaller than that of the connecting disk 41, which provides space for the connection of the coil flexible clamping assembly 2, is conducive to improving the compactness of the structure, and shortens the length of the force arm during rotation, resulting in a better reception effect.

[0075] According to a specific embodiment of the present utility model, the pneumatic rotary cylinder includes a cylinder housing 11 and a rotating part 12 that penetrates the cylinder housing 11 and is rotatably connected to the cylinder housing 11. The rotating part 12 includes a connected cylinder turntable 121 and a cylinder column 122. The cylinder turntable 121 is fixedly connected to the cylinder connecting part 4. The cylinder column 122 is provided with a sensor mounting section 123 at one end away from the cylinder turntable 121. The cylinder turntable 121 and the sensor mounting section 123 are respectively located on both sides of the cylinder housing 11. At least one mounting plane 124 is provided on the outside of the sensor mounting section 123. The sensor mounting section 123 is sleeved with a sensor sheet 5. The transplanting and flipping tinning unit 200 also includes two slot-type photoelectric switches 6 that are respectively used in conjunction with the sensor sheet 5 to control the rotation angle of the pneumatic rotary cylinder.

[0076] In this embodiment, the pneumatic rotary cylinder is a purchased component. The cylinder column 122 provides the rotational force. Mounted at the rear end of the cylinder column 122 (sensor mounting section 123) is a sensor plate 5. The sensor plate 5 is disc-shaped in the center and features a fan-shaped protrusion on the outside. The sensor plate 5 rotates with the cylinder column 122. When the fan-shaped protrusion passes through the sensing area of the slot-shaped photoelectric switch 6, the switch activates, providing control instructions for the electrical control system of the transplanting, flipping, and tinning device 400. This structure allows for flexible control of the rotation angle of the pneumatic rotary cylinder.

[0077] According to the specific embodiment of the present invention, the transplanting and flipping tinning unit 200 also includes: a cylinder transition frame 7, a tinning sliding mounting frame 8, a tinning floating joint 9 and a tinning slide rail module 10; the tinning lifting cylinder 3 includes a tinning cylinder body 31 and a tinning cylinder rod 32; the cylinder transition frame 7 is a rectangular frame as a whole; the tinning sliding mounting frame 8 includes a tinning sliding horizontal frame 81 and a tinning sliding vertical frame 82 that are collectively surrounded by a right-angled plate; the tinning slide rail module 10 includes a tinning slide rail 101 and a tinning slider 102 that are connected in a sliding manner; the tinning cylinder body 31 is fixedly installed on On the fixed mounting frame 100, the tin immersion cylinder rod 32 is installed on the tin immersion sliding horizontal frame 81 through the tin immersion floating joint 9; one side of the tin immersion sliding vertical frame 82 is connected to one side of the cylinder transition frame 7, and the other side of the tin immersion sliding vertical frame 82 is fixedly connected to the tin immersion slider 102, and the tin immersion slide rail 101 is fixed on the fixed mounting frame 100; the side of the cylinder transition frame 7 away from the tin immersion sliding vertical frame 82 is fixedly connected to the tin immersion cylinder body 31; the sensor installation section 123 and the sensor sheet 5 are both located in the cylinder transition frame 7, and the slot-type photoelectric switch 6 is installed on the inner arm of the cylinder transition frame 7.

[0078] In this embodiment, the structure of the cylinder transition frame 7 can provide two mounting surfaces to connect the tin-immersion rotary drive 1 and the tin-immersion sliding mounting frame 8. The interior of the cylinder transition frame 7 has a receiving cavity that can accommodate the sensor mounting section 123 and the sensor sheet 5.

The two ends of the pressure air circuit 0221 are respectively the air source connecting end 0222 and the air claw connecting end 0223. The air source connecting end 0222 is connected to the rotary joint 023 for introducing a pressure air source; the air claw connecting end 0223 is connected to the driving air circuit inlet for introducing pressure gas to drive the two wire twisting clamping fingers to open and / or close.

[0081] In this embodiment, the wire twisting unit 300 is used to implement the "wire winding" process, and the transplanting and flipping tinning device 400 is used to implement the "tinning" process. Since "wire winding" is a prerequisite for "tinning", the wire twisting unit 300 is integrated into the transplanting and flipping tinning device 400 to form the wire twisting and tinning integrated module 500 for the hollow cup motor coil production line of the utility model. The structure is compact and reasonable, and a modular structure is formed, providing conditions for the automated production line of motor coils.

[0082] The structure and function of the thread end twisting unit 300 are described in detail below.

[0083] The twisted wire sliding mounting frame 01 is used to provide an installation base.

[0084] The pneumatic opening and closing clamp 021 for thread twisting is an existing two-finger pneumatic opening and closing clamp structure, and the pneumatic opening and closing clamp 021 for thread twisting can be directly purchased from outside. It can be a normally closed type or a normally open type, and its normally closed or normally open state can be controlled by a spring. When it is a normally closed type, a pressure air source is used to drive the two wire twisting clamp fingers to open; when it is a normally open type, a pressure air source is used to drive the two wire twisting clamp fingers to close; of course, the pneumatic opening and closing clamp 021 for thread twisting can also be a structure that is completely driven to close and open by a pressure air source. Since the rotating main shaft 022 of this embodiment can only provide one driving air path, a reversing structure needs to be set in the pneumatic opening and closing clamp 021 for thread twisting to control the driving air source to be led to the pneumatic opening and closing clamp 021 for thread twisting to control the air cavity of the two wire twisting clamp fingers to open, or to the air cavity of the pneumatic opening and closing clamp 021 for controlling the closure of the two wire twisting clamp fingers.

[0085] The driving air circuit inlet is arranged on the side of the wire twisting clamp housing 0213, which is the structure of the existing wire twisting pneumatic opening and closing clamp 021, so there is no need to change the position of the driving air circuit inlet of the existing two-finger wire twisting pneumatic opening and closing clamp.

[0086] The thread twisting and rotating drive 024 is used to provide rotational power. It can have various structures, such as a combination of a motor and a belt drive. Alternatively, the thread twisting and rotating drive 024 may be a structure where the motor drives a gear train, which includes a driving gear connected to the motor and a driven gear connected to the rotating main shaft 022. The driving gear and the driven gear mesh with each other. Rotation of the motor drives the driving gear, which in turn drives the driven gear and the rotating main shaft 022 to rotate as a whole.

[0087] The rotating spindle 022 is used to transmit the rotational power of the thread twisting rotation drive 024 to the thread twisting pneumatic opening and closing clamp 021. The rotating spindle 022 is also used to lead the pressurized air source into the thread twisting pneumatic opening and closing clamp 021 to drive the thread twisting pneumatic opening and closing clamp 021 to open and / or close.

[0088] The main utility model features of this embodiment are: the inner hole of the rotating spindle 022, which is aligned with the rotation center of the pneumatic opening and closing clamp 021 for thread twisting, is used to provide a driving air source for the pneumatic opening and closing clamp 021 for thread twisting. When the pneumatic opening and closing clamp 021 for thread twisting rotates, the rotating spindle 022 and the pneumatic opening and closing clamp 021 rotate as a whole. Pressurized air is introduced through the pressure air circuit 0221 inside the rotating spindle 022, and the other end of the air pipe connected to the rotary joint 023 is connected to the rotating spindle 022. The rotary joint 023 is used to connect the pressure air source and the pressure air circuit 0221 inside the rotating spindle 022, and can also achieve relative rotation.

[0089] The use process of the present utility model is as follows: after completing the "winding" and "rolling" of the motor coil, the thread end twisting unit 300 of this embodiment is moved as a whole to the vicinity of the thread ends to be twisted at the last circle of the hollow cup coil semi-finished product at both ends, and the thread twisting pneumatic opening and closing clamp 021 clamps the two thread ends to be twisted at the last circle of the hollow cup coil semi-finished product at both ends. Driven by the thread twisting rotation drive 024, the thread twisting pneumatic opening and closing clamp 021 rotates, driving the two thread ends to be twisted to rotate, and twisting the two ends of the thread ends to be twisted together, thus realizing the automatic twisting process of the thread ends to be twisted. After the twisting is completed, the thread twisting pneumatic opening and closing clamp 021 opens, and the product is transferred to the next process. The use of the thread end twisting unit 300 of this embodiment can provide conditions for the automatic production of motor coils.

[0090] According to the specific implementation of the present invention, the two clamping claws are respectively the first twisting clamping finger 0211 and the second twisting clamping finger 0212, the first twisting clamping finger 0211 is connected to the first twisting hook needle 0213, the second twisting clamping finger 0212 is connected to the second twisting hook needle 0214, the first twisting hook needle 0213 is away from the first twisting clamping finger 0211. One end is provided with a wire pressing wire 0215 protruding toward the second twisting hook needle 0214, and the second twisting hook needle 0214 is away from the second twisting clamping finger 0212. One end is provided with a pressure head 0216 protruding toward the first wire twisting hook needle 0213, and the pressure head 0216 is provided with a recessed wire pressing groove 0217 at the position opposite to the annular wire pressing wire 0215; the wire end twisting unit 300 also includes a wire twisting telescopic drive 03, and the wire twisting telescopic drive 03 includes a wire twisting cylinder body 031; the wire twisting and tinning integrated module 500 for the hollow cup motor coil production line also includes a drag chain mounting plate 600, and the two sides of the drag chain mounting plate 600 are respectively fixed on the same side of the tinning cylinder body 31 and the wire twisting cylinder body 031.

[0091] In this embodiment, the added wire twisting hook needle (the first wire twisting hook needle 0213 and the second wire twisting hook needle 0214) is used to replace the wire twisting clamping finger (the first wire twisting clamping finger 0211 and the second wire twisting clamping finger 0212) to directly contact the wire end to be twisted of the motor coil. The wire pressing wire 0215 is made of steel wire and has a certain elasticity. When the wire pressing wire 0215 is clamped with the wire pressing groove 0217, the elastic wire pressing wire 0215 can press the wire end to be twisted into the wire pressing groove 0217. The wire pressing groove 0217 can limit the wire end to be twisted to prevent the wire from sliding. Therefore, using the structure of this embodiment, the wire pressing wire 0215 cooperates with the wire pressing groove 0217 to press the wire end to be twisted. Compared with directly using the first wire twisting clamping finger 0211 and the second wire twisting clamping finger 0212 to clamp the wire end to be twisted, the clamping stability is better. The drag chain mounting plate 600 is used to install the drag chain to centrally accommodate the air pipes of the pneumatic actuators in the wire twisting and tinning integrated module 500 for the hollow cup motor coil production line of the present invention.

[0092] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium; it can mean internal communication between two elements, or a "transmission connection," i.e., a power connection through various appropriate means such as a belt drive, a gear drive, or a sprocket drive. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
