Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automation equipment, and in particular to a fixing plate assembly device. Background Art
[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate conversion mechanism.
[0003] Linear motors are increasingly used in automation, machine tools and other fields. Linear motors are mainly used in combination with a mover and a stator. The interior of the mover is composed of several coils mounted on a rectangular iron core. When the coils are wound around the rectangular iron core, it is difficult for the two smaller ends of the rectangular iron core to fit tightly with the coils. This can easily cause the coil and the iron core to shake relative to each other during use, making the mover movement unstable and easily damaging the linear motor. Therefore, it is necessary to insert a fixing plate into the two gaps at both ends of the coil and the iron core to fill the gap. In addition, considering that the long-term motion state of the linear motor may cause the winding of the coil and the iron core to become loose, in order to further ensure the stability of the assembly of the two, it is generally necessary to make the fixing plate and the above-mentioned gap have an interference fit.
[0004] In the prior art, the stator is typically installed manually into the gap. Because the gap and the stator have an interference fit, inserting the stator into the gap requires significant external force. Therefore, workers typically use a rubber hammer to hammer the stator into the gap. On the one hand, manual assembly requires a significant amount of manpower, requiring multiple hammerings to fully hammer the stator into the gap, resulting in low assembly efficiency. On the other hand, manual hammering can easily result in the coil being struck due to inaccurate force applied, causing deformation or even damage to the coil, adding additional costs. Summary of the Invention

[0012] Furthermore, the loading module also includes a third driving member connected to the axis of the steering wheel, and a groove is opened on the peripheral side of the steering wheel perpendicular to its axis to form the accommodating space.

The fourth drive member drives the material tray to slide along the first slide rail, and the sliding path passes under the steering wheel and intersects with the moving path of the pressure rod driven by the first drive member.
[0014] Furthermore, the press-fitting module also includes a coil conveying assembly, which includes a third slide rail and a fifth driving member, and the fifth driving member drives the coil to slide along the third slide rail, and the sliding path at least passes through the installation position.

In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising the element.
[0037] When manufacturing the mover of a linear motor, several coils need to be wound onto the core group first. The gaps formed between the small ends of a single core and the coils serve as mounting holes. The coils are placed in the mounting position, and then the fixing plates are pressed into the mounting holes at the mounting position. The fixing plates and the mounting holes have an interference fit.
[0038] In one embodiment, Figure 1-3 As shown, an assembly device includes a mounting base, a positioning module 20 and a press-fitting module 30, and the positioning module 20 and the press-fitting module 30 are both arranged on the mounting base. The positioning module 20 includes a material tray 21, and a first slot 211 is provided on the material tray 21 for accommodating a fixing plate. The internal size of the first slot 211 matches the fixing plate, so that the fixing plate can pass through the first slot 211. The press-fitting module 30 includes a pressure rod 31 and a first driving member 32 that drives and connects the pressure rod 31. The movement path of the pressure rod 31 driven by the first driving member 32 at least partially passes through the first slot 211, and when the pressure rod 31 passes through the first slot 211, the fixing plate is driven out of the first slot 211 and enters the installation position. Among them, the first driving member 32 can be a lifting cylinder, a lifting oil cylinder, or a screw rod with a motor, etc.
[0039] During use, the material tray 21 is first placed under the pressure rod 31, so that the first slot 211 and the end of the pressure rod 31 away from the first driving member 32 are aligned, and the iron core assembly wound with the coil is placed in the installation position below the material tray 21, so that a mounting hole on the circumference of one of the iron cores is aligned with the first slot 211. Then, the fixing plate is placed in the first slot 211, and the first driving member 32 is activated, driving the pressure rod 31 to move downward and squeeze the fixing plate in the first slot 211, driving the fixing plate into the installation position and inserting it into the mounting hole at the installation position, thereby achieving press-fitting of the fixing plate.
[0040] In this embodiment, the assembly device uses the inner side wall of the first slotted hole 211 on the material tray 21 to limit the position of the fixed plate, thereby preventing the fixed plate from tilting and slipping. The first driving member 32 is used to drive the pressure rod 31 to press the fixed plate into the mounting hole, thereby realizing mechanical automation press-fitting. There is no need for manual labor to consume a lot of physical strength to hammer the fixed plate, thus saving labor. The first driving member 32 can completely press the fixed plate into the mounting hole by one press-fit, without the need for workers to repeatedly hammer, thereby improving assembly efficiency. The mounting hole on the peripheral side of the iron core is directly opposite to the first slotted hole 211, and the pressure rod 31 presses the fixed plate directly against the first slotted hole 211 until it completely enters the mounting hole. During the entire press-fitting process, the pressure rod 31 will not come into contact with the iron core and the coil on its peripheral side, thereby reducing the possibility of deformation or damage to the iron core or the coil, improving the final yield rate, and reducing production costs.
[0041] In one embodiment, Figure 4 As shown, the positioning module 20 also includes a positioning mechanism 22, which constrains the fixing plate and releases the constraint on the fixing plate when the pressure rod 31 enters the first slot 211. The positioning mechanism 22 includes a second driving member and a baffle 221 slidably connected to the material tray 21. The second driving member drives the baffle 221 and the material tray 21 to slide relative to each other. The baffle 221 has a constrained state, blocking the bottom opening of the first slot 211, and a free state, opening the bottom opening of the first slot 211.
[0042] During use, the material tray 21 is first removed from beneath the pressure rod 31. The baffle 221 slides and closes the lower opening of the first slotted hole 211, placing the baffle 221 in a restrained position. The fixing plate is then inserted into the first slotted hole 211 from the top. Because the baffle 221 seals the lower opening of the first slotted hole 211, the fixing plate will not fall through the first slotted hole 211. The material tray 21 with the fixing plate is then placed beneath the pressure rod 31. The core assembly with the coil wound around it is placed in the mounting position below the material tray 21. The second drive member drives the baffle 221 and the material tray 21 to slide relative to each other, causing the baffle 221 to open the lower opening of the first slotted hole 211, placing the baffle 221 in a retracted position. Finally, the first drive member 32 is activated, driving the pressure rod 31 downward and squeezing the fixing plate within the first slotted hole 211, forcing the fixing plate into the mounting position and inserting it into the mounting hole, thereby press-fitting the fixing plate.
[0043] The press-fit module 30 is typically fixed to the mounting base, while the first slotted hole 211 on the material tray 21 is through-hole. To prevent the stator from slipping out of the first slotted hole 211, the material tray 21 and the core assembly with the coil wound thereon are typically placed in a preset position below the press rod 31 before the stator is placed into the first slotted hole 211 for press-fitting. However, due to the limited space below the press rod 31, loading the stator into the first slotted hole 211 is difficult and can easily lead to accidental contact or even damage to other components. This embodiment incorporates a positioning mechanism 22 that uses a baffle 221 to seal the lower opening of the first slotted hole 211. The stator can then be loaded into the first slotted hole 211 in a wide area away from the exterior of the press-fit module 30, where it is prevented from slipping. The material tray 21 is then placed in a preset position below the press rod 31. The baffle 221 is then slid open to fully open the first slotted hole 211, allowing the press rod 31 to press the stator into the mounting hole through the first slotted hole 211. The positioning mechanism 22 of this embodiment allows the material tray 21 to be loaded at any position, making loading of the fixing plate easier to operate, reducing accidental contact or even damage to other components, and improving assembly efficiency.
[0044] Specifically, a stopper 224 is fixed to the mounting base, facing the baffle 221. A slot is defined on the lower surface of the material tray 21 through the first slot 211, within which the baffle 221 slides. The positioning mechanism 22 also includes an elastic member 222 and a stopper 223. The stopper 223 is fixed to one end of the slot on the material tray 21. The ends of the elastic member 222 are respectively fixedly connected to the stopper 223 and the baffle 221. The baffle 221 defines a third slot extending therethrough. When the elastic member 222 is in a free state, the third slot is offset from the first slot 211, and the baffle 221 closes the lower opening of the first slot 211. A second rail is also fixed to the mounting base, with the material tray 21 slidably connected to the second rail. A second drive member drives the material tray 21, driving the material tray 21 to move the baffle 221 along the second rail. Driven by the second drive member, the baffle 221 moves along the second rail, passing through at least the stopper 224. When the baffle 221 contacts the stop block 224 on the mounting base, the second driving member continues to drive the material tray 21 to move. At this time, the baffle 221 squeezes the elastic member 222, causing the baffle 221 and the material tray 21 to slide relative to each other. Finally, the third slot and the first slot 211 are aligned, and the opening below the first slot 211 is opened, allowing the fixed plate to be freely pressed. The second driving member can be a motor or a cylinder, etc., and the elastic member 222 can be a spring, a bellows, etc.
[0045] In other embodiments, the stop block 223 may not be provided, and the end of the elastic member 222 away from the baffle 221 may be directly fixed to the material tray 21, and it is only necessary to ensure that the elastic force of the elastic member 222 is in the sliding direction of the baffle 221. In other embodiments, the second driving member may directly drive the baffle 221, driving the baffle 221 to slide within the chute of the material tray 21, so that the third slot and the first slot 211 are aligned or offset from each other. In other embodiments, the baffle 221 may be slidably connected to the material tray 21 via other structures, and the baffle 221 itself may be configured to close / open the lower opening of the first slot 211 during the sliding process.
[0046] In other embodiments, the positioning mechanism 22 can be a spring, one end of which is fixed on the material tray 21, and the other end abuts against the fixing plate, and presses the fixing plate tightly against the side wall of the first slot 211, thereby preventing the fixing plate from slipping. At the same time, the pressure rod applies a large force to press the fixing plate from the first slot 211 into the installation position, and at the installation position, it is pressed into the installation hole on the coil.
[0047] In one embodiment, a guide channel is further formed on the positioning module 20, one end of the guide channel is connected to the first slot 211, and the other end is opposite to the installation position, and the movement path of the pressure rod 31 driven by the first driving member 32 at least passes through the first slot 211 and the guide channel in sequence. Figure 5 、 6As shown, the positioning module 20 also includes a guide block, which is arranged on the mounting seat. A second through slot is opened on the guide block, and the second slot is a guide channel. The moving path of the pressure rod 31 driven by the first driving member 32 passes through at least the first slot 211 and the second slot in sequence.
[0048] During use, first place the material tray 21, the guide block, and the iron core group wound with the coil under the pressure rod 31 in sequence, so that the pressure rod 31 is aligned with the end of the first driving member 32, the first slot 211, the second slot, and the mounting holes on the side of the iron core from top to bottom. Then the first driving member 32 drives the pressure rod 31 to press the fixing plate through the first slot 211 and the second slot in sequence, and finally is pressed into the mounting hole at the installation position, completing the assembly of the coil fixing plate. Because the fixing plate is relatively thin and slightly long, it is easy to tilt and fall over when being pressed vertically downward into the mounting hole. After the guide block is set, the inner wall of the second slot and the inner wall of the first slot 211 can be used to limit the fixing plate, further reducing the possibility of deviation in the position of the fixing plate and improving the success rate and efficiency of assembly.
[0049] In one embodiment, the end of the guide channel that communicates with the first slotted hole 211 is provided with a first guide slope facing the first slotted hole 211. Specifically, the provision of the first guide slope increases the opening of the guide channel at the end closest to the first slotted hole 211. When the stator slides from the first slotted hole 211 into the guide channel, the first guide slope of the guide channel can increase the area for receiving the stator, allowing the stator to smoothly fall into the guide channel over a wider range. This reduces the possibility of the stator being unable to enter the guide channel due to deviation, thereby improving the error tolerance and the success rate of the stator press-fitting.
[0050] In one embodiment, the material tray 21 is provided with two first slots 211, and the guide block is provided with two second slots opposite thereto. The press-fitting module 30 is provided with two corresponding pressing rods 31. Each pressing rod 31, driven by the first driving member 32, moves along a path that passes through at least its corresponding first slot 211 and second slot in sequence. During use, the two mounting holes on the circumference of a single iron core can be aligned with the two second slots and the two first slots 211, respectively. The two pressing rods 31 can simultaneously press the two fixing plates into the two mounting holes through their corresponding first slots 211 and second slots. This allows both mounting holes within a coil to be filled in one press-fit, saving press-fitting time and improving assembly efficiency.
[0051] In one embodiment, the assembly device further comprises a loading module 10, such as Figure 7-9As shown, the loading module 10 includes a steering disc 13, which is mounted on a mounting base and has a receiving space 131 for placing a fixed plate. The steering disc 13 has a receiving state and a feeding state. When the steering disc 13 is in the receiving state, the fixed plate remains stationary on the steering disc 13. When the steering disc 13 is in the feeding state, the fixed plate tilts downward and slides out of the steering disc 13 and falls into the first slot 211. Specifically, the loading module 10 also includes a third drive member 14, which is driven and connected to the axis of the steering disc 13. The receiving space 131 is formed by a slot on the circumference of the steering disc 13 perpendicular to its axis. The third drive member 14 drives the steering disc 13 to rotate in a vertical plane. When the notch of the receiving space 131 faces upward, the steering disc 13 is in the receiving state. When the notch of the receiving space 131 faces downward, the steering disc 13 is in the feeding state.
[0052] During use, when the steering disc 13 is in the receiving state, the fixing piece is placed from the notch of the accommodating space 131 into the accommodating space 131. The third driving member 14 drives the steering disc 13 to rotate in a vertical plane, driving the steering disc 13 into the feeding state, and the fixing piece slides downward from the accommodating space 131 into the first slot 211 on the material tray 21.
[0053] Existing material conveying devices, such as the vibrating plate 15, generally load materials horizontally onto the workstation to be processed. Therefore, it is difficult for existing material conveying devices to directly load the fixed plate into the vertical first slot 211 on the material plate 21. The direction-changing plate 13 in this embodiment can use the accommodating space 131 in the receiving state to receive the horizontally placed fixed plate, and then change the state of the direction-changing plate 13 to the feeding state to achieve the direction change of the fixed plate, and finally feed the changed-direction fixed plate into the first slot 211.
[0054] In one embodiment, Figure 7-9 As shown, multiple grooves can be opened on the circumferential side of the steering wheel 13 perpendicular to its axis to form multiple accommodating spaces 131. Each accommodating space 131 can receive a fixed plate and deliver it to the first slot 211 after the fixed plate is changed in direction. The provision of multiple accommodating spaces 131 improves the efficiency of the steering wheel 13 in changing the direction of the fixed plate, thereby improving the assembly efficiency of the fixed plate.
[0055] In one embodiment, Figure 7-9As shown, the accommodating space 131 defines a first opening 132 on a side perpendicular to the axis of the steering wheel 13. When the steering wheel 13 is in the receiving state, the fixing piece enters the accommodating space 131 through the first opening 132. The loading module 10 also includes a baffle 17 fixed to the mounting base. The baffle 17 is arranged along the circumference of the steering wheel. The baffle 17, facing the bottom of the steering wheel 13, defines a second opening 133 extending therethrough. When the steering wheel 13 is in the feeding state, the fixing piece falls through the second opening 133 into the first slot 211.
[0056] During use, the output end of the material conveying device can be connected to the accommodating space 131 through the first opening 132. The stator can be pushed into the accommodating space 131 at the connection. Compared to dropping from a notch in the accommodating space 131, the stator in this embodiment is more smoothly and controllably loaded onto the steering wheel 13. The baffle 17 can block the notch in the accommodating space 131, thereby preventing the stator from sliding off before the steering wheel 13 rotates to the feeding state. When the steering wheel 13 rotates to the feeding state, the portion of the stator in the accommodating space 131 reaches the second opening 133, where it slides out of the second opening 133 under the influence of gravity and falls into the first slot 211 below. The steering wheel 13 is cylindrical, and the baffle 17 is made of a rigid material. In other embodiments, the steering wheel 13 can have other shapes, and the baffle 17 can be made of a flexible material that fits snugly around the circumference of the steering wheel 13.
[0057] In one embodiment, a second guide slope is provided at one end of the second opening 133 near the steering wheel 13. The second guide slope can provide a guide when the fixing plate slides downward from the accommodating space 131. On the one hand, it can also avoid sudden changes in the direction of the fixing plate. On the other hand, it can guide the fixing plate to a preset position, making its sliding more controllable.
[0058] In one embodiment, the steering disc 13 and the pressure rod 31 are staggered with each other in the horizontal plane, and the loading module 10 also includes a first slide rail 11 and a fourth drive member 12. The fourth drive member 12 drives the material tray 21 to slide along the first slide rail 11, and the sliding path passes directly below the second opening 133 and intersects with the moving path of the pressure rod 31 driven by the first drive member 32.
[0059] The fourth drive member 12 can drive the material tray 21 away from the pressure rod 31, receiving the stator that falls after the steering wheel changes direction, completing the loading of the stator. It can then drive the material tray 21 to move under the pressure rod 31 to press-fit the stator. In this embodiment, the steering wheel 13 and the pressure rod 31 are offset relative to each other in the horizontal plane, reducing interference between them. The first slide rail 11 is provided to facilitate the transport of the stator between the offset steering wheel 13 and the pressure rod 31. The material tray 21 is moved by mechanical control, eliminating the need for manual handling, further enhancing the automation of the assembly device, saving labor, and improving assembly efficiency.
[0060] In other embodiments, the fourth driving member 12 and the second driving member can be the same driving member, the first slide rail 11 and the second slide rail are the same slide rail, and the fourth driving member 12 drives the material tray 21 to slide along the first slide rail 11 toward the pressure rod 31. When the first material trough is directly below the pressure rod 31, the blocking block 224 squeezes the blocking plate 221, so that the third slot hole and the first slot hole 211 are opposite, and the positioning mechanism 22 opens the lower end opening of the first slot hole 211 to facilitate the pressure rod 31 to press the fixing plate.
[0061] In one embodiment, the loading module 10 further includes a sensor 18 for sensing the fixed sheet, and the sensor 18 is fixed on the baffle 17. When the steering disc 13 is in the material receiving state, the detection direction of the sensor 18 is toward the notch of the accommodating space 131 and faces the accommodating space 131. After the sensor 18 senses that the fixed sheet is loaded on the steering disc 13, it can send a signal to the third driving member 14, and the third driving member 14 drives the steering disc 13 to rotate. The loading module 10 further includes a vibration disc 15, and the discharge end 16 of the vibration disc 15 is connected to the first opening 132 of the accommodating space 131. A large number of fixed sheets can be stored in the vibration disc 15 and the fixed sheets can be arranged in an orderly manner, and then loaded into the accommodating space 131 on the steering disc 13 through the discharge end 16. Among them, the sensor 18 can be an infrared sensor 18, and can also be set as a pressure sensor fixed on the bottom surface of the accommodating space 131.
[0062] In this embodiment, the setting of the steering plate 13, sensor 18 and vibration plate 15 further improves the degree of automation of the assembly device, reduces manual intervention, and can quickly and efficiently complete the assembly of a large number of fixed plates, further improving assembly efficiency, saving labor and time, and reducing costs.
[0063] In one embodiment, the press-fitting module 30 further includes a coil conveying assembly, which includes a third slide rail and a fifth drive member. The fifth drive member drives the coil to slide along the third slide rail, with the sliding path passing through at least the installation position. The coil conveying assembly can utilize the fifth drive member to sequentially drive multiple coils to the installation position, press-fit the fixed plate on the coils at the installation position, and then sequentially drive the multiple coils away from the installation position. The coil conveying assembly can achieve automatic loading of the coils.
[0064] In one embodiment, Figure 10 As shown, the press-fitting module 30 also includes a second press-fitting assembly, which includes a press-fitting block 35 and a sixth driving member 34. The shape of the press-fitting end 351 of the press-fitting block 35 for press-fitting matches the coil. The sixth driving member 34 drives the press-fitting block 35 to move to a press-fitting position for secondary press-fitting. The fifth driving member drives the coil to at least pass through the installation position of the first press-fitting and the press-fitting position of the second press-fitting in sequence.
[0065] Specifically, the sixth drive member 34 drives the press-fitting block 35 to extend and retract, with the end of the press-fitting block 35 configured to match the coil of the stator assembly. In practice, the top surface of the coil of the stator assembly is flush with the stator, while the core is slightly higher than the top surface of the coil. Therefore, the press-fitting block 35, which matches the coil of the stator assembly, can completely press the stator into the mounting hole.
[0066] During the process of pressing the fixing plate, the assembly device can achieve the goal of completely pressing the fixing plate into the mounting hole to a preset depth by presetting the distance between the mounting hole and the pressure rod 31, as well as the downward pressing distance of the pressure rod 31. However, during the actual production and processing process, there may be some small deviations in the distance between the mounting hole and the pressure rod 31, as well as the downward pressing distance of the pressure rod 31. The actual downward pressing distance of the pressure rod 31 is difficult to accurately control. Therefore, the position of the fixing plate and the mounting hole cannot be well guaranteed, which can easily affect the quality of the final product and reduce the yield rate.
[0067] This embodiment incorporates a second press-fit assembly. First, the first driver 32 drives the pressure rod 31 to press the majority of the stator into the mounting hole, pre-pressing the stator. The coil, pre-pressed with the stator, is then moved directly beneath the press-fit block 35. Because the lower surface of the press-fit block 35 matches the shape of the coil with the stator, the lower surface of the press-fit block 35 can completely press the stator into the mounting hole, completing the assembly. Compared to press-fitting using only the pressure rod 31, this embodiment offers greater control over the press-fitting operation, resulting in a higher yield rate for the assembled coils and lower production costs.
[0068] In one embodiment, the press-fitting module 30 also includes a fixing mechanism, which has a fixed state in which the coil is pressed against the coil, and a circulating state in which the coil is released. When the fixing mechanism is in the fixed state, the coil is pressed against the fixed plate, and when the fixing mechanism is in the circulating state, the coil slides along the third slide rail. Specifically, the fixing mechanism includes a coil fixing block and a seventh driving member 33, the seventh driving member 33 drives the connected coil fixing block, and the seventh driving member 33 drives the coil fixing block to extend and abut against / away from the coil. When the coil fixing block is pressed against the coil, the fixing mechanism is in a fixed state, and when the coil fixing block is away from the coil, the fixing mechanism is in a circulating state.
[0069] When the fixed plate is pressed into the mounting hole between the coil and the iron core, the pressure rod 31 or the press-fitting block 35 is required to provide a large external force. When the external force is transmitted to the coil and the iron core through the fixed plate, the coil and the iron core are prone to move, causing the fixed plate and the mounting hole to be unable to face each other, affecting the subsequent press-fitting. In this embodiment, a seventh driving member 33 and a coil fixing block are provided. Before the fixed plate is press-fitted, the coil fixing block is first driven to abut against the coil by the seventh driving member 33, so that the fixing mechanism is in a fixed state, and then the fixed plate is press-fitted. This can reduce the displacement of the coil and the iron core, and the fixed plate and the mounting hole are more likely to be in a facing position relationship. The press-fitting of the fixed plate can also be easier, and the assembly efficiency is improved. After the press-fitting is completed, the seventh driving member 33 drives the coil fixing block away from the coil, and the fixing mechanism is in a circulating state. The fifth driving member can drive the coil to slide along the third slide rail.
[0070] Furthermore, the guide block can be connected to the seventh driving member 33 in a transmission manner, and the seventh driving member 33 can synchronously drive the guide block and the coil fixing block, that is, the seventh driving member 33 can drive the coil fixing block to abut against the coil, and at the same time drive the upper and lower openings of the second slot hole on the guide block to face the first slot hole 211 and the mounting hole respectively. This setting makes the overall structure of the device tighter. At the same time, when a coil is pressed into the fixing plate, the seventh driving member 33 can be used to move the guide block first, and after the next coil to be installed with the fixing plate is placed in the preset position, the guide block can be moved back to the top of the mounting hole to reduce interference and facilitate the coil transfer operation.
[0071] The use process of the above-mentioned assembly device is roughly as follows:
[0072] First, workers place a large number of stators into the vibrating plate 15. The vibrating plate 15 starts to sort the stators, and then the stators are loaded onto the turning plate 13 through the discharge end 16 of the vibrating plate 15.
[0073] Then, after the sensor 18 senses the fixed piece on the steering disc 13, it sends a command to the third driving member 14, driving the steering disc 13 to rotate 180 degrees in the vertical plane. At the same time, the fourth driving member 12 drives the material tray 21 to slide along the first slide rail 11 to the bottom of the steering disc 13. Under the action of gravity, the fixed piece falls into the first slot 211 of the material tray 21, completing the direction change and loading of the horizontally placed fixed piece.
[0074] Then, the fourth driving member 12 drives the material tray 21 to slide along the first slide rail 11 to the bottom of the pressure rod 31. The seventh driving member 33 drives the coil fixing block to press against the coil. At the same time, the upper and lower openings of the second slot of the guide block are driven to face the first slot 211 and the mounting hole respectively. The first driving member 32 drives the pressure rod 31 to pre-press the fixing plate into the mounting hole.
[0075] Finally, the fifth driving member moves the pre-pressed coil to just below the pressing block 35 , and the sixth driving member 34 drives the pressing block 35 to completely press the fixing plate into the mounting hole on the coil.
