Description
Technical Field
[0001] This utility model relates to a pin mounting structure, and more particularly to a pin mounting device for a stepper motor lead screw shaft. Background Technology
[0002] Currently, the production process of stepper motor lead screws typically requires the insertion of pins into the screw ends. Existing pin insertion operations are mostly manual, which is not only time-consuming and labor-intensive but also susceptible to human error, leading to inaccuracies and low efficiency. Therefore, there is an urgent need for equipment that can automate the continuous operation of lead screw feeding, sorting, identification of orientation, hole position recognition, and pin insertion, thereby improving production efficiency, reducing labor costs, and ensuring processing accuracy. Utility Model Content
[0003] The purpose of this utility model is to provide a stepper motor lead screw pin installation device, which realizes a series of operations such as lead screw feeding and sorting, identification of positive and negative orientation, identification of hole position and insertion of pin in an automated manner, thereby solving the problems of cumbersome and inefficient manual operation in the prior art.
[0004] This utility model provides the following technical solution: A stepper motor lead screw pin installation device includes a feeding device, a distributing device, a forward and reverse adjustment conveying device, a waiting station, a hole position identification and adjustment station, a plugging station, a finishing station, a synchronous conveying device, a rotation adjustment device, and a plugging device. The feeding device receives the lead screw and sequentially conveys it to the distributing device. The distributing device separates the lead screws and sequentially conveys them to the area below the forward and reverse adjustment conveying device. The forward and reverse adjustment conveying device grips the lead screw and places it in place by the distributing device. After the lead screw is corrected in both forward and reverse directions, it is fed to the waiting station. The waiting station, hole position identification and adjustment station, insertion station, and end station are arranged in sequence and are used to receive the lead screws transported by the synchronous conveying device in sequence. At the hole position identification and adjustment station, the rotary adjustment device is used to grab one end of the lead screw to rotate and adjust the hole position of the lead screw to be vertically distributed in the axial direction. At the insertion station, the insertion device is used to press the pin into the hole after the pin is inserted into the hole. In actual operation, multiple sets of lead screws can be placed in the feeding device, which then transfers them to the sorting device. The sorting device separates one set of lead screws and transfers them to the underside of the forward / reverse adjustment conveying device. Here, the lead screw end can be detected to determine whether the screw is in the forward or reverse direction when it reaches its destination—that is, whether the threaded part of the lead screw head is in front of or behind the conveyor. Based on this, the forward / reverse adjustment conveying device can correct the position before picking up the lead screw and placing it at the waiting station. If it is in the forward direction, no adjustment is needed; if it is in the reverse direction, it can be rotated 180° before being placed in position, and then the synchronous conveying device will transport it. The lead screw from the waiting station is moved to the hole position identification and adjustment station. At the hole position identification and adjustment station, the rotary adjustment device can grasp one end of the lead screw to rotate and adjust the hole position of the lead screw so that the axis is vertically distributed. At the same time, the synchronous transport device is also used to transport the lead screw from the hole position identification and adjustment station to the insertion station. At the insertion station, after the pin is aligned with the hole and inserted, the pressing group of the insertion device can press the pin into the hole. After the pressing is completed, the synchronous transport device is also used to transport the lead screw from the insertion station to the end station. Thus, the pin installation of a set of lead screws can be completed automatically, which solves the problems of cumbersome manual operation and low efficiency in the existing technology.
[0005] Preferably, the feeding device includes a set of inclined plates with their bottom ends tilted towards the distributing device. Above the bottom end of the inclined plates, a partition is arranged for only one set of lead screws to roll through. The distributing device includes a baffle plate supported at the bottom end of the inclined plates. A set of insert plates is also inserted between the baffle plate and the inclined plates. The top end of the insert plates is provided with a V-shaped groove for only one set of lead screws to roll into the inclined plates. The bottom end of the insert plates is connected to the driving end of the insert cylinder. The insert cylinder is used to lift the insert plates so that one end of the V-shaped groove aligns with one end of the guide groove. A push rod located on one side of the baffle plate is driven by the push cylinder to push the lead screw in the V-shaped groove along the guide groove to below the forward and reverse adjustment conveying device. The end of the guide groove below the forward and reverse adjustment conveying device is also provided with a sensor for detecting whether the lead screw head is forward or reverse. That is, here, the sensor can determine whether the threaded end of the lead screw is in front or behind by sensing the diameter of the lead screw head, thereby ensuring the position of the hole and ensuring that the hole is aligned during the insertion station.
[0006] Preferably, the forward and reverse adjustment conveying device includes a rotary drive cylinder installed at the drive end of the three-axis slide module and forward and reverse conveying grippers installed at the drive end of the rotary drive cylinder. The forward and reverse conveying grippers are used to grab the lead screw at the end of the guide groove and convey it to the upper part of the waiting station under the drive of the three-axis slide module. The rotary drive cylinder is used to adjust the rotation angle of the forward and reverse conveying grippers according to the forward or reverse result detected by the sensor to adapt to the placement position of the waiting station.
[0007] Preferably, both the waiting station and the hole position identification and adjustment station are equipped with two sets of V-groove fixtures driven by a positioning cylinder. The positioning cylinder is used to switch the V-groove fixture alignment and synchronous transport device. Thus, after the forward and reverse adjustment transport device transports the lead screw to one of the V-groove fixtures, the positioning cylinder can be operated to drive the V-groove fixture to align with the synchronous transport device. At this time, the transport action of the synchronous transport device and the re-transport operation of the forward and reverse adjustment transport device can be carried out synchronously. Similarly, after the rotary adjustment device adjusts the lead screw of one set of V-groove fixtures, the positioning cylinder can be operated to drive the V-groove fixture to align with the synchronous transport device. At this time, the transport action of the synchronous transport device and the re-rotation adjustment operation of the rotary adjustment device can be carried out synchronously, thereby greatly improving the efficiency of the transition.
[0008] Preferably, the rotation adjustment device includes an adjustment gripper mounted on the drive end of the drive motor, a detection camera for detecting whether the axial position of the hole on the V-groove tool is vertically distributed, and the adjustment gripper for clamping one end of the lead screw and rotating under the drive of the rotary motor to adjust the axial position of the hole to be vertically distributed.
[0009] Preferably, the synchronous transport device includes a base plate installed on the drive end of the X-axis linear module. A set of mounting plates is connected to the base plate via a Z-axis top cylinder. Three sets of synchronous transport grippers are mounted on the mounting plates. The synchronous transport grippers are used to sequentially transfer the lead screw to the waiting station, the hole position identification and adjustment station, the insertion station, and the end station under the reciprocating drive of the X-axis linear module. The Z-axis top cylinder is used to drive the three sets of synchronous transport grippers to perform lifting and lowering gripping and alignment operations after the X-axis linear module completes the position switch. That is, in the initial position, the three sets of synchronous transport grippers are aligned sequentially to the waiting station, the hole position identification and adjustment station, and the insertion station. After gripping the lead screw, the Z-axis top cylinder is raised and the X-axis linear module drives the three sets of synchronous transport grippers to move forward in a staggered motion, so that the three sets of synchronous transport grippers are aligned sequentially to the hole position identification and adjustment station, the insertion station, and the end station. At this point, all three sets of lead screws have moved forward one position, realizing the synchronous transmission of movement.
[0010] Preferably, the insertion device includes a pressure block that is driven to move up and down by a lifting cylinder. The pressure block has a pin hole for the pin to pass through and a guide hole for the pressure rod to pass through. The pin hole and the guide hole intersect and the guide holes are vertically distributed. The pressure rod is driven by the pressure cylinder to press the pin that has been fed into the guide hole into the hole of the lead screw.
[0011] Preferably, the insertion station includes a V-shaped positioning groove positioned below the pressure block and V-shaped clamping blocks arranged on both sides of the V-shaped positioning groove for inserting into the V-shaped positioning groove under the drive of the clamping cylinder to clamp and position the lead screw. The bottom of the V-shaped positioning groove is also provided with a positioning rod, which extends into the hole of the lead screw under the drive of the positioning cylinder for positioning.
[0012] The beneficial effects of this utility model are as follows: In actual operation, multiple sets of lead screws can be placed in the feeding device, which transmits the lead screws to the sorting device. The sorting device then separates a set of lead screws and transmits them to the underside of the forward / reverse adjustment conveying device. Here, the lead screw end can be photographed to determine whether the lead screw is in the forward or reverse direction when it reaches its position, i.e., whether the threaded position of the lead screw head is in front of or behind the conveyor. Based on this, the forward / reverse adjustment conveying device can correct the position before picking up the lead screw and placing it at the waiting station. That is, if it is in the forward direction, no adjustment is needed; if it is in the reverse direction, it can be rotated 180° before placement, thus synchronizing the operation. The conveying device transports the lead screw from the waiting station to the hole position identification and adjustment station. At the hole position identification and adjustment station, the rotary adjustment device can grasp one end of the lead screw to rotate and adjust the hole position of the lead screw so that the axis is vertically distributed. At the same time, the synchronous conveying device is also used to transport the lead screw from the hole position identification and adjustment station to the insertion station. At the insertion station, after the pin is aligned with the hole, the pressing group of the insertion device can press the pin into the hole. After the pressing is completed, the synchronous conveying device is also used to transport the lead screw from the insertion station to the end station. Thus, the pin installation of a set of lead screws can be completed automatically, which solves the problems of cumbersome manual operation and low efficiency in the existing technology.

[0014] like Figure 1-10 As shown, a stepper motor lead screw shaft pin 102 installation device, in this embodiment, includes a feeding device 1, a distributing device 2, a forward and reverse adjustment conveying device 3, a waiting station 4, a hole position identification and adjustment station 5, a plugging station 6, an ending station 7, a synchronous conveying device 8, a rotation adjustment device 9, and a plugging device 10. The feeding device 1 is used to receive the lead screw and sequentially convey it to the distributing device 2. The distributing device 2 is used to separate the lead screws and sequentially convey them to the area below the forward and reverse adjustment conveying device 3. The forward and reverse adjustment conveying device 3 is used to grip the distributing device. Device 2 delivers the lead screw to the designated position and corrects its forward and reverse positions before feeding it to the waiting station 4. The waiting station 4, hole position identification and adjustment station 5, insertion station 6, and end station 7 are arranged in sequence and are used to receive the lead screws transported by the synchronous conveying device 8 in sequence. At the hole position identification and adjustment station 5, the rotation adjustment device 9 is used to grab one end of the lead screw to rotate and adjust the hole position of the lead screw to a vertical distribution in the axial direction. At the insertion station 6, the insertion device 10 is used to press down the pin 102 into the hole after the pin 102 is aligned with the hole position. In actual operation, multiple sets of lead screws can be placed in the feeding device 1. The feeding device 1 is used to transfer the lead screws to the sorting device 2. Then, the sorting device 2 separates a set of lead screws and transfers them to the front and back adjustment conveying device 3. Here, the end of the lead screw can be detected to determine whether the position of the lead screw when it is in place is forward or reverse, that is, whether the thread position of the lead screw head is in front of or behind the conveyor. Based on this, the front and back adjustment conveying device 3 can perform position correction before grabbing the lead screw and placing it in the waiting station 4. That is, if it is forward, no adjustment is needed; if it is reverse, it can be rotated 180° before being placed in position. Then, the synchronous conveying device 8 transports the lead screw in the waiting station 4. The screw rod is positioned at the hole identification and adjustment station 5. At this station, the rotary adjustment device 9 can grip one end of the screw rod to rotate and adjust the hole position of the screw rod so that the axial direction is vertically distributed. At the same time, the synchronous transport device 8 is used to transport the screw rod from the hole identification and adjustment station 5 to the insertion station 6. At the insertion station 6, after the pin 102 is aligned with the hole position and inserted, the pressing group of the insertion device 10 can press the pin 102 into the hole position. After the pressing is completed, the synchronous transport device 8 is used to transport the screw rod from the insertion station 6 to the end station 7. Thus, the automatic installation of the pin 102 of a set of screw rods can be completed, which solves the problems of cumbersome manual operation and low efficiency in the prior art.
[0015] The feeding device 1 includes a set of inclined plates 11 with their bottom ends facing the distributing device 2. Above the bottom end of the inclined plates 11, there is a partition plate 12 that allows only one set of lead screws to roll through. The distributing device 2 includes a baffle plate 21 supported on the bottom end of the inclined plates 11. A set of insert plates 22 is also inserted between the baffle plate 21 and the inclined plates 11. The top end of the insert plates 22 is provided with a V-shaped groove that allows only one set of lead screws to roll into the inclined plates 11. The bottom end of the insert plates 22 is connected to the drive end of the insert cylinder 23. The insert cylinder 23 is used to lift the insert plates 22 so that the V-shaped groove aligns with the guide. One end of the groove 24 is connected, and the push rod 25 located on one side of the baffle 21 is driven by the push cylinder 26 to push the lead screw in the V-shaped groove along the guide groove 24 to the bottom of the forward and reverse adjustment conveying device 3. The end of the guide groove 24 below the forward and reverse adjustment conveying device 3 is also equipped with a sensor for detecting whether the lead screw head is forward or reverse. That is, here, the sensor can determine whether the threaded end of the lead screw is in front or behind by sensing the diameter of the lead screw head, so as to ensure the position of the hole and ensure that the hole is aligned when inserting at the insertion station 6.
[0016] The forward and reverse adjustment conveying device 3 includes a rotary drive cylinder 32 installed at the drive end of the three-axis slide module 31 and forward and reverse conveying grippers 33 installed at the drive end of the rotary drive cylinder 32. The forward and reverse conveying grippers 33 are used to grab the lead screw at the tail end of the guide groove 24 and transport it to the upper part of the waiting station 4 under the drive of the three-axis slide module 31. The rotary drive cylinder 32 is used to adjust the rotation angle of the forward and reverse conveying grippers 33 according to the forward or reverse result detected by the sensor to adapt to the placement position of the waiting station 4.
[0017] Both the material waiting station 4 and the hole position identification and adjustment station 5 are equipped with two sets of V-groove fixtures 42 driven by the positioning cylinder 41. The positioning cylinder 41 is used to switch the V-groove fixtures 42 to the synchronous transport device 8. Thus, after the forward and reverse adjustment transport device 3 transports the lead screw to one of the V-groove fixtures 42, the positioning cylinder 41 can be operated to drive the V-groove fixture 42 to align with the synchronous transport device 8. At this time, the transport action of the synchronous transport device 8 and the re-transport operation of the forward and reverse adjustment transport device 3 can be carried out synchronously. Similarly, after the rotary adjustment device 9 has adjusted the lead screw of one set of V-groove fixtures 42, the positioning cylinder 41 can be operated to drive the V-groove fixture 42 to align with the synchronous transport device 8. At this time, the transport action of the synchronous transport device 8 and the re-rotation adjustment operation of the rotary adjustment device 9 can be carried out synchronously, thereby greatly improving the efficiency of the transition.
[0018] The rotary adjustment device 9 includes an adjustment jaw 92 mounted on the drive end of the drive motor 91. The detection camera is used to detect whether the axial position of the hole on the V-groove tooling 42 is vertically distributed. The adjustment jaw 92 is used to clamp one end of the lead screw and rotate under the drive of the rotary motor to adjust the axial position of the hole to be vertically distributed.
[0019] The synchronous transport device 8 includes a base plate 82 mounted on the drive end of the X-axis linear module 81. A set of mounting plates 83 is connected to the base plate 82 via a Z-axis top cylinder 84. Three sets of synchronous transport grippers 85 are mounted on the mounting plates 83. Under the reciprocating drive of the X-axis linear module 81, the synchronous transport grippers 85 are used to sequentially transfer the lead screw at the waiting station 4, the hole position identification and adjustment station 5, the insertion station 6, and the end station 7. The Z-axis top cylinder 84 is used to drive the three sets of synchronous transport grippers 85 after the X-axis linear module 81 has completed its drive position. The transport grippers 85 perform lifting and lowering gripping and alignment operations. That is, in the initial position, the three sets of synchronous transport grippers 85 are aligned sequentially with the waiting station 4, the hole position identification and adjustment station 5, and the insertion station 6. After gripping the lead screw, the Z-axis top cylinder 84 lifts and the X-axis linear module 81 drives the three sets of synchronous transport grippers 85 to move forward in a staggered motion, so that the three sets of synchronous transport grippers 85 are aligned sequentially with the hole position identification and adjustment station 5, the insertion station 6, and the end station 7. At this point, all three sets of lead screws have moved forward one position, realizing the synchronous transmission of movement.
[0020] The insertion device 10 includes a pressure block 101 that is driven to rise and fall by a lifting cylinder. The pressure block 101 has a pin hole 103 for the pin 102 to pass through and a guide hole 104 for the pressure rod to pass through. The pin hole 103 and the guide hole 104 intersect and the guide hole 104 is vertically distributed. The pressure rod is driven by the pressure cylinder to press the pin 102, which is fed into the guide hole 104, into the hole of the lead screw.
[0021] The insertion station 6 includes a V-shaped positioning groove 61 positioned below the pressure block 101 and V-shaped clamping blocks 63 arranged on both sides of the V-shaped positioning groove 61 for inserting into the V-shaped positioning groove 61 under the drive of the clamping cylinder 62 to clamp and position the lead screw. The bottom of the V-shaped positioning groove 61 is also provided with a positioning rod 64, which extends into the hole of the lead screw under the drive of the positioning cylinder for positioning.
[0022] The working principle of this utility model is as follows: In actual operation, multiple sets of lead screws can be placed in the feeding device 1. The feeding device 1 is used to transfer the lead screws to the sorting device 2. Then, the sorting device 2 separates a set of lead screws and transfers them to the underside of the forward and reverse adjustment conveying device 3. Here, the end of the lead screw can be photographed to determine whether the position of the lead screw when it is in place is forward or reverse, that is, whether the thread position of the lead screw head is in front of or behind the conveyor. Based on this, the forward and reverse adjustment conveying device 3 can perform position correction before grabbing the lead screw and placing it in the waiting position 4. That is, if it is forward, no adjustment is needed; if it is reverse, it can be rotated 180° before being placed in the position. Then, the synchronous conveying device 8 transports the waiting... The lead screw at material station 4 is moved to hole position identification and adjustment station 5. At hole position identification and adjustment station 5, the rotary adjustment device 9 can grab one end of the lead screw to rotate and adjust the hole position of the lead screw to a vertical distribution along the axis. At the same time, the synchronous transport device 8 is also used to transport the lead screw at hole position identification and adjustment station 5 to insertion station 6. At insertion station 6, after the pin 102 is aligned with the hole position and inserted, the pressing group of insertion device 10 can press the pin 102 into the hole. After pressing is completed, the synchronous transport device 8 is also used to transport the lead screw at insertion station 6 to end station 7. Thus, the automatic installation of the pin 102 of a set of lead screws can be completed, solving the problems of cumbersome manual operation and low efficiency in the prior art.
