Description

Technical Field

[0001] This invention relates to the field of insulating ring assembly technology, and more specifically to an automatic insulating ring feeding device. Background Technology

[0002] Insulating rings (such as commutator insulating rings in motors and insulating washers in transformers) are key components for achieving electrical isolation in electromechanical products. Traditional manual loading methods are not only labor-intensive and inefficient, but also prone to contaminating the insulating ring surface with sweat and dust from hands, affecting insulation performance. Furthermore, manual placement makes it difficult to guarantee repeatability and positioning accuracy, leading to increased assembly defects in subsequent processes. Therefore, existing technologies mostly employ automated loading devices to improve loading efficiency. With the development of automated assembly lines, the requirements for the efficiency, cleanliness, and positioning accuracy of insulating ring loading are increasingly stringent.

[0003] Existing automatic feeding devices for insulating rings mostly use vibratory feeders for direct feeding, combined with simple pneumatic grippers for grasping. However, in actual operation, the automatic feeding devices frequently encounter the following problems: material accumulation and ring jamming easily occur at the vibratory feeder outlet; for thin-walled flexible insulating rings, the gripping process easily leads to deformation and detachment of the insulating rings; for insulating rings with distinct front and back sides or specific angular installation requirements, such as... Figure 1 The insulating ring product shown has a symmetrical ring structure, but there is a notch on one side of the bottom of the insulating ring and no notch on the other side. The notch at the bottom of the insulating ring is the only feature to identify whether the posture of the insulating ring is accurate when it is installed. For this kind of insulating ring that needs to be circumferentially positioned to confirm the direction, existing devices generally lack reliable means of insulating ring posture identification and adjustment. Summary of the Invention

[0004] Therefore, the present invention aims to solve the problems of poor reliability in recognizing the posture of ring-mounted workpieces and difficulty in adjustment in the existing automatic feeding device for insulating rings, and thus provides an automatic feeding device for insulating rings.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: An automatic feeding device for insulating rings includes: The feeding module includes a storage bin, a discharge drive connected to the storage bin, and a feeding conveying assembly connected to the discharge port of the storage bin.

The feeding conveying assembly is adapted to convey the workpieces in the storage bin one by one from the input end to the output end. The material handling module includes a material handling base, a material handling translation drive connected to the material handling base, a material handling lifting drive connected to the material handling translation drive, and a material handling rod connected to the material handling lifting drive, wherein the material handling rod is located at the output end of the material feeding and conveying assembly; An adjustment module, located on one side of the material handling module, includes a rotary drive, an adjustment station located at the rotation center of the rotary drive, an adjustment gripper located above the adjustment station, an elastic positioning member on the adjustment gripper, a positioning detection member on the rotary drive and located on one side of the elastic positioning member, and an adjustment drive connected to the adjustment gripper. The adjustment station is suitable for placing a workpiece, the rotary drive is suitable for driving the workpiece on the adjustment station to rotate, the adjustment drive is suitable for driving the adjustment gripper to move closer to or away from the adjustment station, the elastic positioning member is suitable for positioning the identification features of the workpiece, and the positioning detection member is also electrically connected to the rotary drive. When the positioning detection member fails to locate the identification features of the workpiece with the elastic positioning member, the rotary drive continues to rotate; when the positioning detection member locates the identification features of the workpiece with the elastic positioning member, the rotary drive stops rotating. An assembly module is located on the side of the positioning module away from the feeding module, and is on the same straight line as the positioning module and the feeding module. The assembly module is provided with an assembly station suitable for placing workpieces. A feeding module, located on one side of the picking module, the adjusting module, and the assembly module, includes a feeding lateral movement drive, a feeding lifting drive connected to the feeding lateral movement drive, and a feeding gripping assembly connected to the feeding lifting drive. The feeding lateral movement drive is adapted to drive the feeding gripping assembly to transport the workpiece located in the picking module to the adjusting module, and is also adapted to transport the workpiece on the adjusting module to the assembly module.

[0006] Furthermore, the adjusting gripper is provided with a guide groove, and the positioning detection component includes a pin connected to the adjusting gripper, an elastic element sleeved on the outer periphery of the pin, and a slider connected to the adjusting gripper. The first end of the elastic element is fixed in the bottom of the guide groove at the end away from the adjustment position, and the second end of the elastic element is fixedly sleeved on the first end of the pin. The second end of the pin extends out of the guide groove and toward the adjustment position. The slider is slidably disposed in the guide groove and fixedly connected to the first end of the pin. The positioning detection component is installed on the adjusting drive component and is located on one side of the slider.

[0007] Furthermore, the feeding and conveying assembly includes a conveyor belt connected to the discharge port of the storage bin, a first detection element disposed at the input end of the conveyor belt, and a second detection element disposed at the output end of the conveyor belt. The first detection element is electrically connected to the discharge drive unit, and the second detection element is electrically connected to the material picking module.

[0008] Furthermore, the feeding module also includes a material blocking and lifting drive component located on one side of the output end of the conveyor belt and a material blocking rod connected to the driving end of the material blocking and lifting drive component; the output end of the conveyor belt is sequentially provided with a pre-discharge position and a discharge position, the pre-discharge position being close to the feeding module and the discharge position being close to the positioning module, the second detection component being located on one side of the discharge position, the material blocking and lifting component being electrically connected to the second detection component, and the material blocking and lifting drive component being adapted to drive the material blocking rod to approach or move away from the pre-discharge position of the feeding and conveying component.

[0009] Furthermore, the conveyor belt is provided with a contoured conveying groove extending along its conveying length direction, and the cross-section of the contoured conveying groove is adapted to the shape of the workpiece cross-section.

[0010] Furthermore, the adjustment station is provided with a positioning block suitable for placing the workpiece, and the end of the positioning block that contacts the workpiece with the material picking rod is a cylindrical structure.

[0011] Furthermore, the material feeding gripping assembly includes two sets of material feeding grippers that are spaced apart and connected to the material feeding lifting drive component.

[0012] Furthermore, the unloading gripper includes an unloading drive and two gripping arms connected to the unloading drive. The unloading drive is adapted to drive the two gripping arms to move closer or further apart from each other. Each of the two gripping arms is provided with a positioning groove that matches the cross-sectional shape of the workpiece on the side where they move closer together.

[0013] Furthermore, the material picking module also includes a limiting rod fixedly connected to the material picking translation drive component. The material picking rod is driven by the material picking lifting drive component to move along the height direction of the limiting rod, and the top surface of the limiting rod is higher than the bottom of the contour conveying trough.

[0014] Furthermore, the material receiving base is provided with an infeed position, a separation position and a material receiving position in sequence. The infeed position is located near the feeding module, the material receiving position is located near the adjusting module, and the separation position is located between the feeding module and the adjusting module.

[0015] The technical solution of this invention has the following advantages: 1. The automatic insulation ring feeding device provided by the present invention uses a storage bin of a feeding module to hold workpieces. A discharge drive unit transports the workpieces to the discharge port of the storage bin and continuously drives them to the input end of a feeding conveying assembly. The feeding conveying assembly then transports the workpieces one by one from the input end to the output end. Subsequently, a picking module uses a picking translation drive unit and a picking lifting drive unit to drive a picking rod to receive the workpieces from the output end of the feeding conveying assembly. After the picking rod receives the workpiece, the translation drive unit further moves the picking rod to ensure that the workpiece on it... The workpiece detaches from the feeding and conveying assembly and moves toward the adjusting assembly; then, the feeding lateral drive and feeding lifting drive of the feeding module drive the feeding gripping assembly, causing the feeding gripping assembly to move between the picking rod of the picking module and the rotary drive of the adjusting module, thereby transferring the workpiece located in the picking module to the adjusting station of the rotary drive of the adjusting module; then, the adjusting drive drives the adjusting gripper to move toward the axis of the adjusting station, so that the elastic positioning element abuts against the outer wall of the workpiece, and the rotary drive drives the workpiece to rotate, when... When the elastic positioning component fails to locate the identification feature of the workpiece, it remains abutted against the outer wall of the workpiece. When the elastic positioning component locates the identification feature, it springs into the identification feature. Simultaneously, the positioning detection component confirms whether the elastic positioning component is aligned with the identification feature of the bottom notch of the workpiece. The positioning detection component is also electrically connected to the rotary drive component. When the positioning detection component fails to locate the identification feature of the workpiece, the rotary drive component continues to rotate. When the positioning detection component locates the identification feature of the workpiece, the rotary drive component stops rotating. With this setup, the workpiece is fed through the feeding module, received through the picking module, and moved from the picking module to the positioning module and then to the assembly module through the unloading module. This achieves automated feeding, eliminating the contamination problems caused by manual feeding. The elastic positioning component effectively identifies the unique identification feature of the workpiece, and in conjunction with the rotary positioning component and the positioning detection component, ensures precise adjustment of the workpiece, effectively guaranteeing the feeding efficiency, cleanliness, and positional accuracy of the automatic insulating ring feeding device.

[0016] 2. The automatic feeding device for insulating rings provided by this invention has a guide groove on the adjusting gripper. The positioning detection component includes a pin connected to the adjusting gripper, an elastic element sleeved on the outer periphery of the pin, and a slider connected to the adjusting gripper. The first end of the elastic element is fixed in the bottom of the guide groove away from the adjusting position, and the second end of the elastic element is fixedly sleeved on the first end of the pin. The second end of the pin extends out of the guide groove and towards the adjusting position. The slider is slidably disposed in the guide groove and fixedly connected to the first end of the pin. The positioning detection component is installed on the adjusting drive component and located on one side of the slider. With this configuration, when the second end of the pin abuts against the outer wall of the workpiece, the slider is in the detectable position of the positioning detection component. The rotating drive component then drives the workpiece on the adjusting position to continue rotating until the pin positions itself to the identification feature of the workpiece. At this time, the slider follows the pin and moves towards the workpiece on the adjusting position, moving out of the detectable position of the positioning detection component. The rotating drive component then drives the workpiece on the adjusting position to stop rotating synchronously.

[0017] 3. The automatic feeding device for insulating rings provided by this invention includes a feeding and conveying assembly comprising a conveyor belt connected to the outlet of a storage bin, a first detection element disposed at the input end of the conveyor belt, and a second detection element disposed at the output end of the conveyor belt. The first detection element is electrically connected to a discharge drive element, and the second detection element is electrically connected to a picking module. With this configuration, workpieces are conveyed via the conveyor belt. The first and second detection elements detect in real time whether there are workpieces at the input and output ends of the conveyor belt. When the first detection element detects no workpiece at the input end of the conveyor belt, the discharge drive element controls the discharge, conveying the workpiece to the input end of the conveyor belt. When the second detection element detects a workpiece at the output end of the conveyor belt, the picking translation drive element and the picking lifting drive element of the picking module drive the picking rod to remove the workpiece from the output end of the conveyor belt, facilitating subsequent picking and conveying by the unloading module. Simultaneously, the real-time monitoring of the presence and absence of workpieces at the input and output ends of the conveyor belt by the first and second detection elements prevents material accumulation and jamming.

[0018] 4. The automatic feeding device for insulating rings provided by the present invention further includes a material blocking and lifting drive component located on one side of the output end of the conveyor belt and a material blocking rod connected to the driving end of the material blocking and lifting drive component; the output end of the conveyor belt is sequentially provided with a pre-discharge position and a discharge position, the pre-discharge position being close to the feeding module and the discharge position being close to the adjustment module; a second detection component is located on one side of the discharge position; the material blocking and lifting component is also electrically connected to the second detection component; the material blocking and lifting drive component is adapted to drive the material blocking rod to approach or move away from the pre-discharge position of the feeding and conveying component. With this configuration, when the second detection element detects a workpiece at the discharge position of the conveyor belt output end, the material blocking and lifting element controls the material blocking rod to move towards the pre-discharge position of the conveyor belt output end, and continues to move until it is locked into the inner ring of the workpiece at the pre-discharge position. This can prevent subsequent workpieces from continuing to move forward and causing material accumulation on the conveyor belt if the workpiece at the discharge position has not yet left the conveyor belt. When the second detection element detects no workpiece at the discharge position, the material blocking and lifting element controls the material blocking rod to move away from the conveyor belt, so that the material blocking rod is disengaged from the workpiece, so that the workpiece at the pre-discharge position can move to the discharge position, allowing subsequent workpieces to move forward and ensuring the continuous and orderly conveying of workpieces.

[0019] 5. The automatic insulated ring feeding device provided by this invention has a contoured conveying groove extending along its conveying length on the conveyor belt. The cross-section of the contoured conveying groove matches the shape of the workpiece's cross-section. This design improves the stability of the conveyor belt when conveying workpieces, prevents workpieces from tilting or falling over, and ensures that workpieces maintain the same posture on the conveyor belt. This eliminates the need for individual workpiece posture adjustments during subsequent workpiece handling by the picking module, effectively improving picking efficiency.

[0020] 6. The automatic insulating ring feeding device provided by the present invention has a positioning block suitable for placing the workpiece at the adjustment station. Both the positioning block and the end of the picking rod that contacts the workpiece are cylindrical structures. This arrangement allows the shape of the ends of the positioning block and the picking rod that contact the workpiece to match the shape of the workpiece, thereby limiting the workpiece and achieving reliable separation of the thin-walled insulating ring. This improves the stability of the positioning block and the picking rod when picking up the workpiece and prevents the workpiece from detaching after being picked up.

[0021] 7. The automatic feeding device for insulating rings provided by the present invention includes a feeding gripper assembly comprising two sets of feeding claws spaced apart and connected to the feeding lifting drive component. This configuration, using two feeding claws for feeding and discharging, allows for simultaneous feeding from the feeding module and feeding to the positioning module, thereby reducing the overall feeding and discharging interval time and improving feeding and discharging efficiency.

[0022] 8. The automatic feeding device for insulating rings provided by the present invention includes a feeding gripper comprising a feeding drive and two gripping arms connected to the feeding drive. The feeding drive is adapted to drive the two gripping arms to move closer or further apart. Each of the sides of the two gripping arms that move closer together is provided with a positioning groove adapted to the cross-sectional shape of the workpiece. This configuration allows the workpiece to be gripped tightly against the outer wall of the workpiece through the positioning grooves on the gripping arms, without compressing, deforming, or detaching the workpiece. This enables non-destructive gripping and flexible feeding of thin-walled insulating ring workpieces.

[0023] 9. The automatic feeding device for insulating rings provided by the present invention further includes a limiting rod fixedly connected to the feeding translation drive component. The feeding rod is driven by the feeding lifting drive component to move along the height direction of the limiting rod, and the top surface of the limiting rod is higher than the bottom of the contour conveying trough. With this configuration, by setting the limiting rod and ensuring its top surface is higher than the bottom of the contour conveying trough, when the feeding translation drive component moves the feeding rod to a position corresponding to the workpiece at the discharge position, the limiting rod limits the end of the discharge position. This prevents the workpiece from falling off the conveyor belt before the feeding rod extends into the workpiece at the discharge position. After the feeding lifting drive component drives the feeding rod into the workpiece at the discharge position, the feeding translation drive component drives the limiting rod to move towards the adjustment module in the same direction as the feeding rod. During this movement, the limiting rod can still limit the workpiece on the feeding rod side, preventing the workpiece from falling off the feeding rod.

[0024] 10. The automatic feeding device for insulating rings provided by the present invention has an infeed position, a separation position, and a picking position sequentially arranged on the picking base. The infeed position is located near the feeding module, the picking position is located near the adjusting module, and the separation position is located between the feeding module and the adjusting module. With this arrangement, when the picking translation drive drives the picking rod to move to the infeed position, the position of the picking rod corresponds to the position of the discharge position. The picking translation drive drives the picking rod to move, and the picking rod reciprocates between the feeding module and the adjusting module, thereby transferring a single insulating ring workpiece from the infeed position through the separation position to the picking position, so that the single workpiece is completely separated from the feeding module, realizing the orderly one-by-one conveying of workpieces and preventing material accumulation and jamming.

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figures 1-7 An automatic feeding device for insulating rings is shown, comprising a feeding module 1, a picking module 2, a positioning module 3, and an assembly module 4, and further comprising a discharging module 5 located on one side of the positioning module 3. Specifically, the feeding module 1 includes a storage bin 11, a discharge drive connected to the storage bin 11, and a feeding conveying assembly connected to the discharge port of the storage bin 11. One end of the feeding conveying assembly near the storage bin 11 is an input end, and the other end is an output end. The feeding conveying assembly is adapted to convey the workpieces in the storage bin 11 one by one from the input end to the output end. like Figure 1 , Figure 4 As shown, the material picking module 2 includes a material picking base 21, a material picking translation drive 22 connected to the material picking base 21, a material picking lifting drive 23 connected to the material picking translation drive 22, and a material picking rod 24 connected to the material picking lifting drive 23. The material picking rod 24 is located at the output end of the material feeding and conveying assembly. like Figure 1 , Figure 5 , Figure 6 , Figure 9As shown, the adjustment module 3 is located on one side of the material handling module 2, including a rotary drive 31, an adjustment station 32 located at the rotation center of the rotary drive 31, an adjustment gripper 33 connected to the body of the rotary drive 31 and located above the adjustment station 32, an elastic positioning element 34 located on the adjustment gripper 33, a positioning detection element 35 located on the rotary drive 31 and located on one side of the elastic positioning element 34, and an adjustment drive 36 connected to the adjustment gripper 33. The adjustment station 32 is suitable for placing workpieces, the rotary drive 31 is suitable for driving the workpieces on the adjustment station 32 to rotate, the adjustment gripper 33 is located at the same height as the feeding and conveying assembly, the adjustment drive 36 is suitable for driving the adjustment gripper 33 to move closer to or away from the adjustment station 32, and the elastic positioning element 34 is suitable for... Figure 9 The identification feature 61 of the workpiece 6 is used for positioning. The positioning detection element 35 is also electrically connected to the rotary drive element 31. When the positioning detection element 35 fails to position the identification feature 61 of the workpiece by the elastic positioning element 34, the rotary drive element 31 continues to rotate. When the positioning detection element 35 positions the identification feature 61 of the workpiece by the elastic positioning element 34, the rotary drive element 31 stops rotating. like Figure 1 , Figure 7 As shown, the assembly module 4 is located on the side of the adjustment module 3 away from the feeding module 1, and is on the same straight line as the adjustment module 3 and the feeding module 1. The assembly module 4 includes an assembly base 41 and an assembly station 42 disposed on the assembly base 41. The assembly station 42 is suitable for placing workpieces. like Figure 1 , Figure 8 As shown, the feeding module 5 is located on one side of the picking module 2, the positioning module 3, and the assembly module 4. It includes a feeding transverse drive 51, a feeding lifting drive 52 connected to the feeding transverse drive 51, and a feeding gripping assembly 53 connected to the feeding lifting drive 52. The feeding transverse drive 51 is adapted to drive the feeding gripping assembly 53 to transport the workpiece located in the picking module 2 to the positioning module 3, and is also adapted to transport the workpiece on the positioning module 3 to the assembly module 4.

[0032] This automatic insulated ring feeding device uses a feeding module 1 to hold workpieces in its storage bin 11. A discharge drive unit transports the workpieces to the discharge port of the storage bin 11 and continuously drives them to the input end of the feeding conveyor assembly. The feeding conveyor assembly then transports the workpieces one by one from the input end to the output end. Subsequently, the picking module 2 uses a picking translation drive 22 and a picking lifting drive 23 to drive a picking rod 24 to receive the workpieces from the output end of the feeding conveyor assembly. After receiving the workpieces, the translation drive assembly moves the picking rod 24 to detach the workpieces from the feeding conveyor assembly and move them towards... The adjusting component moves; then, the feeding horizontal movement drive 51 and feeding lifting drive 52 of the feeding module 5 drive the feeding gripping component 53, causing the feeding gripping component 53 to move between the picking rod 24 of the picking module 2 and the rotary drive 31 of the adjusting module 3, thereby transferring the workpiece located in the picking module 2 to the adjustment station 32 of the rotary drive 31 of the adjusting module 3; then, the adjusting drive 36 drives the adjusting gripper to move toward the axis of the adjustment station 32, so that the elastic positioning component 34 abuts against the outer wall of the workpiece, and the rotary drive 31 drives the workpiece to rotate, when the elastic positioning component 34... When the identification feature 61 of the workpiece is not located, the elastic positioning element 34 remains abutting against the outer wall of the workpiece. When the elastic positioning element 34 locates the identification feature 61 of the workpiece, the elastic positioning element 34 springs into the identification feature 61. At the same time, the positioning detection element 35 can confirm whether the elastic positioning element 34 is aligned with the identification feature 61 of the bottom notch of the workpiece. The positioning detection element 35 is also electrically connected to the rotary drive element 31. When the positioning detection element 35 and the elastic positioning element 34 fail to locate the identification feature 61 of the workpiece, the rotary drive element 31 continues to rotate until the positioning detection element 35 and the elastic positioning element 34 locate the identification feature of the workpiece. At time 61, the rotary drive component 31 stops rotating. With this setup, the workpiece is fed through the feeding module 1, received through the picking module 2, and moved from the picking module 2 to the positioning module 3 and then to the assembly module 4 through the unloading module 5. This achieves automated feeding, eliminating the pollution problems caused by manual feeding. The unique identification feature 61 of the workpiece 6 is effectively identified by the elastic positioning component 34. Combined with the rotary positioning component and the positioning detection component 35, the precise adjustment of the workpiece is ensured, effectively guaranteeing the feeding efficiency, cleanliness, and positional accuracy of the automatic feeding device for insulating rings.

[0033] In this embodiment, as Figure 5 , Figure 6As shown, the adjustment module 3 includes an adjustment fixing base 38, and a rotary drive 31 is fixedly installed on the adjustment fixing base 38. The adjustment gripper 33 has a guide groove 37. The positioning detection component 35 includes a pin 342 connected to the adjustment gripper 33, an elastic element 341 sleeved on the outer periphery of the pin 342, and a slider 343 connected to the adjustment gripper 33. The first end of the elastic element 341 is fixed in the bottom of the guide groove 37 at the end away from the adjustment position 32, and the second end of the elastic element 341 is fixedly sleeved on the first end of the pin 342. The second end of the pin 342 extends out of the guide groove 37 and toward the adjustment position 32. The slider 343 is slidably disposed in the guide groove 37 and is fixedly connected to the first end of the pin 342. The positioning detection component 35 is installed on the adjustment drive 36 and is located on one side of the slider 343. With this configuration, when the second end of the ejector pin 342 abuts against the outer wall of the workpiece, the slider 343 is located in the detectable position of the positioning detection element 35. Then, the rotary drive 31 drives the workpiece on the adjustment station 32 to continue rotating until the ejector pin 342 positions the identification feature of the workpiece. At this time, the slider 343 moves with the ejector pin 342 toward the workpiece direction of the adjustment station 32 and moves out of the detectable position of the positioning detection element 35. Then, the rotary drive 31 drives the workpiece on the adjustment station 32 to stop rotating synchronously.

[0034] Specifically, the positioning drive unit 36 ​​is connected to two positioning grippers 33, and the positioning drive unit 36 ​​can drive the two positioning grippers 33 to move closer or further apart. The two positioning grippers 33 have the same structure. The positioning drive unit 36 ​​is provided with two positioning detection elements 35, and the two positioning detection elements 35 are configured one-to-one with the two positioning grippers 33. Specifically, the positioning drive unit 36 ​​is a gripper cylinder.

[0035] In this embodiment, the material feeding and conveying assembly includes a conveyor belt 12 connected to the outlet of the storage silo 11, a first detection element 15 disposed at the input end of the conveyor belt 12, and a second detection element 16 disposed at the output end of the conveyor belt 12. The first detection element 15 is electrically connected to the discharge drive component, and the second detection element 16 is electrically connected to the material handling module 2. Specifically, a fixed base 17 is installed at the bottom of the conveyor belt 12. Specifically, the positioning detection element 35, the first detection element 15, and the second detection element 16 are all fiber optic positioning sensors. With this setup, workpieces are transported via conveyor belt 12. The first detection element 15 and the second detection element 16 detect in real time whether there are workpieces at the input and output ends of conveyor belt 12. When the first detection element 15 detects that there are no workpieces at the input end of conveyor belt 12, the discharge drive controls the discharge to transport the workpieces to the input end of conveyor belt 12. When the second detection element 16 detects that there are workpieces at the output end of conveyor belt 12, the material picking module 2's material picking translation drive 22 and material picking lifting drive 23 drive the material picking rod 24 to remove the workpieces from the output end of conveyor belt 12, facilitating subsequent gripping and conveying by the unloading module 5. At the same time, the real-time monitoring of the presence or absence of workpieces at the input and output ends of conveyor belt 12 by the first detection element 15 and the second detection element 16 can prevent material accumulation and jamming.

[0036] In this embodiment, the feeding module 1 further includes a material blocking and lifting drive 19 disposed on one side of the output end of the conveyor belt 12 via a fixed bracket 18 and a material blocking rod 110 connected to the driving end of the material blocking and lifting drive 19; the output end of the conveyor belt 12 is sequentially provided with a pre-discharge position 111 and a discharge position 112, the pre-discharge position 111 being close to the feeding module 1 and the discharge position 112 being close to the adjustment module 3, the second detection element 16 being disposed on one side of the discharge position 112, the material blocking and lifting assembly being electrically connected to the second detection element 16, and the material blocking and lifting drive 19 being adapted to drive the material blocking rod 110 to approach or move away from the pre-discharge position 111 of the feeding and conveying assembly. With this configuration, when the second detection element 16 detects a workpiece at the discharge position 112 of the conveyor belt 12, the material blocking and lifting element controls the material blocking rod 110 to move toward the pre-discharge position 111 of the conveyor belt 12, and continues to move until it is engaged in the inner ring of the workpiece at the pre-discharge position 111. This avoids the subsequent workpieces from continuing to move forward and causing material accumulation on the conveyor belt 12 if the workpiece at the discharge position 112 has not been removed from the conveyor belt 12. When the second detection element 16 detects no workpiece at the discharge position 112, the material blocking and lifting element controls the material blocking rod 110 to move away from the conveyor belt 12, so that the material blocking rod 110 is removed from the workpiece, so that the workpiece at the pre-discharge position 111 can move to the discharge position 112, and the subsequent workpieces can move forward, ensuring the continuous and orderly conveying of workpieces.

[0037] In this embodiment, the conveyor belt 12 is provided with a contoured conveying groove 13 extending along its conveying length. The cross-section of the contoured conveying groove 13 is adapted to the shape of the workpiece's cross-section. This arrangement can improve the stability of the conveyor belt 12 when conveying the workpiece, prevent the workpiece from tilting or falling over on the conveyor belt 12, and ensure that the workpiece maintains the same posture on the conveyor belt 12 at all times. This eliminates the need to adjust the workpiece posture one by one when the subsequent material handling module 2 picks up the workpiece, effectively improving material handling efficiency.

[0038] In this embodiment, a positioning block 39 suitable for placing the workpiece is provided on the adjustment station 32. The ends of the positioning block 39 and the picking rod 24 that contact the workpiece are both cylindrical structures. This arrangement allows the shapes of the ends of the positioning block 39 and the picking rod 24 that contact the workpiece to match the shape of the workpiece, thereby limiting the workpiece and achieving reliable separation of the thin-walled insulating ring. This improves the stability of the positioning block 39 and the picking rod 24 when picking up the workpiece and prevents the workpiece from detaching after being picked up.

[0039] Specifically, the rotary drive 31 is a rotary cylinder, which is suitable for driving the adjustment station 32 to rotate along the Z-axis; the adjustment station 32 is a rotating disk connected to the drive end of the rotary cylinder, and the cylindrical positioning block 39 is fixedly connected to the rotation center of the rotating disk.

[0040] In this embodiment, the feeding module 5 further includes a feeding fixing rod 54, and the feeding transverse drive 51 is fixedly connected to the feeding fixing rod 54. The feeding gripping assembly 53 includes two sets of feeding grippers 531 spaced apart and connected to the feeding lifting drive 52. With this configuration, using two feeding grippers 531 for feeding and dispensing allows for simultaneous feeding from the feeding module 2 and feeding to the positioning module 3, thereby reducing the overall feeding and dispensing interval time and improving feeding and dispensing efficiency. Specifically, the positioning fixing seat 38 is fixedly installed on the feeding fixing rod 54 and located below the feeding transverse drive 51.

[0041] In this embodiment, the unloading gripper 531 includes an unloading drive and two gripping arms 533 connected to the unloading drive 532. The unloading drive 532 is adapted to drive the two gripping arms 533 to move closer or further apart. Each of the two gripping arms 533 has a positioning groove 534 adapted to the cross-sectional shape of the workpiece on its side where they move closer together. This configuration allows the gripper to tightly fit the workpiece's outer wall when gripping it via the positioning groove 534 on the gripping arm 533, without compressing, deforming, or causing it to fall off. This enables non-destructive gripping and flexible feeding of thin-walled insulating ring workpieces.

[0042] In this embodiment, the material picking module 2 also includes a limiting rod 25 fixedly connected to the material picking translation drive 22. The material picking rod 24 is driven by the material picking lifting drive 23 to move along the height direction of the limiting rod 25. The top surface of the limiting rod 25 is higher than the bottom of the contour conveying trough 13. With this configuration, by setting a limiting rod 25 and ensuring that the top surface of the limiting rod 25 is higher than the bottom of the contour conveyor trough 13, when the material picking translation drive 22 drives the material picking rod 24 to move to the position corresponding to the workpiece at the discharge position 112, the limiting rod 25 limits the end of the discharge position 112. This ensures that before the material picking rod 24 extends into the workpiece at the discharge position 112, the limiting rod 25 can block the output end of the conveyor belt 12, preventing the workpiece from continuously moving forward and falling off the conveyor belt 12. After the material picking lifting drive 23 drives the material picking rod 24 to extend into the workpiece at the discharge position 112, the material picking translation drive 22 drives the limiting rod 25 to move in the same direction as the material picking rod 24 toward the adjustment module 3. During the movement, the limiting rod 25 can still limit the workpiece on the side of the material picking rod 24, preventing the workpiece from falling off the material picking rod 24.

[0043] In this embodiment, the material handling base 21 is sequentially provided with an infeed position, a separation position, and a material handling position. The infeed position is located near the feeding module 1, the material handling position is located near the adjusting module 3, and the separation position is located between the feeding module 1 and the adjusting module 3. With this configuration, when the material handling translation drive 22 drives the material handling rod 24 to move to the infeed position, the position of the material handling rod 24 corresponds to the position of the discharge position 112. The material handling translation drive 22 drives the material handling rod 24 to move, and the material handling rod 24 reciprocates between the feeding module 1 and the adjusting module 3, thereby transferring a single insulating ring workpiece from the infeed position through the separation position to the material handling position, so that the single workpiece is completely separated from the feeding module 1, realizing the orderly conveying of workpieces one by one and preventing material accumulation and jamming.

[0044] In summary, this automatic insulating ring feeding device uses the storage bin 11 of the feeding module 1 to hold workpieces. The discharging drive unit transports the workpieces to the discharge port of the storage bin 11 and continuously drives them to the input end of the feeding conveying assembly. The feeding conveying assembly then transports the workpieces one by one from the input end to the output end. Subsequently, the picking module 2 uses the picking translation drive 22 and the picking lifting drive 23 to drive the picking rod 24 to receive the workpieces from the output end of the feeding conveying assembly. After receiving the workpieces, the translation drive assembly moves the picking rod 24 to remove the workpieces from the feeding module. The conveying component moves toward the adjusting component; then, through the feeding lateral drive 51 and feeding lifting drive 52 of the feeding module 5, the feeding gripper 53 moves between the feeding rod 24 of the picking module 2 and the rotary drive 31 of the adjusting module 3, thereby transferring the workpiece located in the picking module 2 to the adjusting station 32 of the rotary drive 31 of the adjusting module 3; then, the adjusting drive 36 drives the adjusting gripper 33 to move toward the axis of the adjusting station 32, so that the elastic positioning member 34 abuts against the outer wall of the workpiece, and the rotary drive 31 moves the workpiece. The system rotates, and when the elastic positioning element 34 is not positioned against the identification feature of the workpiece, it remains against the outer wall of the workpiece. When the elastic positioning element 34 is positioned against the identification feature of the workpiece, it springs into the identification feature. Simultaneously, the positioning detection element 35 confirms whether the elastic positioning element 34 is aligned with the identification feature of the bottom notch of the workpiece. The positioning detection element 35 is also electrically connected to the rotary drive element 31. When the positioning detection element 35 and the elastic positioning element 34 are not positioned against the identification feature of the workpiece, the rotary drive element 31 continues to rotate until the positioning detection element 35 and the elastic positioning element 34 are positioned against the identification feature of the workpiece. When the characteristic is reached, the rotary drive 31 stops rotating; with this configuration, the workpiece is fed through the feeding module 1, the workpiece is received through the picking module 2, and the workpiece is moved from the picking module 2 to the positioning module 3 and then to the assembly module 4 through the unloading module 5. This achieves automated feeding, eliminates the pollution problems caused by manual feeding, and effectively identifies the unique identification feature of the workpiece through the elastic positioning component 34. Combined with the rotary positioning component and the positioning detection component 35, it ensures the precise adjustment of the workpiece and effectively guarantees the feeding efficiency, cleanliness and position accuracy of the automatic feeding device for insulating rings.
