Description
Technical Field
[0001] This utility model discloses a stator core manufacturing process equipment, belonging to the field of core manufacturing, specifically involving a stator core multi-station synchronous handling device. Background Technology
[0002] The stator core of an electric motor is the core component of the motor, and it is made by stacking a number of core laminations. The typical manufacturing process of a stator core is as follows: first, silicon steel sheets are stamped into core laminations, and then the core laminations are stacked and formed into a stator core assembly by partial welding or riveting in a mold.
[0003] After the stator core with partial welding is completed, it requires a series of post-processing steps, which typically include visual inspection, weld spatter removal, thickness inspection, surface marking, cleaning, and oiling. For stator cores produced in batches, the post-processing steps are usually implemented using a post-processing production line consisting of multiple specialized process equipment (including weld spatter removal equipment, thickness inspection equipment, surface marking equipment, and cleaning equipment).
[0004] However, the current stator core post-processing production line still suffers from drawbacks such as slow workpiece turnover and low production line efficiency. Furthermore, some post-processing steps still require manual operation, which reduces the production efficiency of stator core post-processing. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes a multi-station synchronous handling device for stator cores, aiming to improve the production efficiency of the stator core post-processing production line. The specific technical solution is as follows:
[0006] A stator core multi-station synchronous transport device includes a long strip base arranged in a left-right direction, a long strip base movable in the left-right direction on the long strip base, and a number of transport components arranged at equal intervals in the left-right direction on the long strip base. The transport components include a gantry fixed on the long strip base, a lifting slide movable in the up-down direction on the same side of the gantry, and a finger cylinder mounted on the lifting slide. Inside the gantry, a vertical cylinder with its lower end fixed to the long strip base is also erected upwards. The piston rod of the vertical cylinder is erected upwards, and a thrust block is fixed on the piston rod of the vertical cylinder. The thrust block is connected to the lifting slide.
[0007] Preferably, the thrust block on the piston rod of the vertical cylinder is fixedly connected to the end face of the lifting slide by bolts.
[0008] As a further improvement of this utility model, the top of the gantry frame is provided with a guide hole, the thrust block is fixed at the middle position of the piston rod of the vertical cylinder, and the upper half of the piston rod of the vertical cylinder is inserted into the guide hole at the top of the gantry frame and slidably connected with the guide hole.
[0009] In this invention, a linear guide rail arranged in the left-right direction is provided between the elongated substrate and the elongated base.
[0010] To improve the stress distribution on the elongated substrate and enhance its resistance to deformation, a further preferred embodiment is that a plurality of sliders are provided on the upper part of the linear guide rail along the direction of the linear guide rail, and the upper end of each slider is fixedly connected to the lower end of the elongated substrate.
[0011] In this invention, left and right traction cylinders are arranged on the elongated base adjacent to the elongated substrate in the left-right direction. A traction block is fixedly arranged on the side of the elongated substrate. The piston rods of the left and right traction cylinders are parallel to the direction of the linear guide rail. The ends of the piston rods of the left and right traction cylinders are fixedly connected to the traction block.
[0012] Preferably, a pair of vertical guide rails are provided on the gantry frame in the vertical direction, and the lifting slide is movably mounted on the pair of vertical guide rails of the gantry frame in the vertical direction.
[0013] Preferably, the vertical guide rail is a cylindrical guide rail, and the lifting slide is provided with guide rail holes that are adapted to the cylindrical guide rail.
[0014] Preferably, the upper end of the vertical guide rail is connected to the crossbeam of the gantry frame, and the lower end of the vertical guide rail is fixedly connected to the elongated base plate.
[0015] In this invention, the finger cylinder is provided with a pair of mechanical finger clamps, and the inner side of the mechanical finger clamps is provided with a detachable clamping block.
[0016] Preferably, the clamping block is a V-shaped clamping block.
[0017] As a further improvement, the stator core multi-station synchronous handling device of this utility model is also equipped with an online self-maintenance cleaner for cleaning and maintaining the mechanical grippers of the finger cylinders. The online self-maintenance cleaner includes a pair of pneumatic blowing nozzles respectively arranged on the elongated base plate below each finger cylinder. The compressed air jet direction of the pair of pneumatic blowing nozzles is respectively upward and obliquely pointed to the pair of mechanical grippers on the finger cylinders.
[0018] By arranging pneumatic purging nozzles on a long strip-shaped substrate, when the synchronous handling device is in an idle state during workpiece handling (without clamping a workpiece on it), a pair of pneumatic purging nozzles can be timely opened to perform pneumatic cleaning on the mechanical clamping fingers of the finger cylinder, preventing dirt from contaminating the workpiece (stator core), and avoiding the drawback of reduced accuracy of the workpiece loading and unloading position caused by dirt remaining on the mechanical clamping fingers, thereby improving the working reliability of the stator core post-processing production line.
[0019] Preferably, a stator core multi-station synchronous handling device of the present utility model further comprises a front and rear moving mechanism. The front and rear moving mechanism includes a pair of front and rear traction cylinders fixedly arranged and a pair of front and rear moving guide rails arranged in the front and rear direction. The lower end of the long strip-shaped base is movably arranged on the front and rear moving guide rails in the front and rear direction; the piston rod of the front and rear traction cylinder is arranged in the front and rear direction, and the front end of the piston rod of the front and rear traction cylinder is fixedly connected to the long strip-shaped base.
[0020] In the present utility model, the multi-station synchronous handling device is an N-station synchronous handling device, and the number of the handling components supporting the N-station synchronous handling device is N - 1.
[0021] A stator core multi-station synchronous handling device of the present utility model further comprises a control system, which realizes the automatic control of the actions of various functional elements (including finger cylinders, vertical cylinders, left and right traction cylinders, front and rear traction cylinders, and pneumatic purging nozzles).
[0022] The present utility model can be matched with a stator core post-processing production line to realize the synchronous handling of stator cores at multiple stations of the production line. It is required that the post-processing stations on the stator core post-processing production line are arranged in a straight line at equal intervals in sequence, and the station interval is equal to the interval of the handling components. At the same time, the multi-station synchronous handling device is arranged adjacent to the stator core post-processing production line, and the positions of the handling components on the multi-station synchronous handling device correspond to the positions of the post-processing stations on the stator core post-processing production line one by one. The working principle of the stator core multi-station synchronous handling device for realizing synchronous handling is as follows:
[0023] (1) Loading: The multi-station synchronous handling device grabs the stator core from the first loading station through the control system, and then sends the grabbed stator core to the next station of the production line through the left and right traction cylinders, and positions the stator core on the positioning fixture of this station; as the loading proceeds rhythmically, stator cores that need corresponding post-processing are finally loaded on each station of the stator core post-processing production line;
[0024] (2) Post-processing and waiting: According to the working rhythm of the stator core post-processing production line, during the corresponding post-processing of the stator core at each station, the multi-station synchronous transport device is in a waiting state; in the waiting state, the mechanical grippers of each finger cylinder in the stator core multi-station synchronous transport device are in a released state.
[0025] (3) Picking up parts: Once the post-processing tasks of the stator cores at each workstation are completed, the multi-station synchronous transport device is immediately started. The control system drives the multi-station synchronous transport device to move forward through the forward and backward moving mechanism, so that the finger cylinder on the transport component reaches the picking position. Then, the mechanical gripper of the finger cylinder is driven to clamp the stator core at the workstation. After it is in place, the vertical cylinder is driven to move, so that the piston rod of the vertical cylinder moves upward, the finger cylinder moves upward, and the stator core clamped on the finger cylinder moves upward, thereby disengaging from the positioning fixture at the workstation. After it is in place, the multi-station synchronous transport device is driven to move backward through the forward and backward moving mechanism to realize the picking up of the stator cores at each workstation.
[0026] (4) Transfer: The control system drives the left and right traction cylinders to move, and the stator cores clamped on the finger cylinders are moved to the next station. Then, the gripped positioning cores are sent forward by the forward and backward moving mechanism until the stator cores are positioned above the positioning fixtures of each station. After they are in place, the vertical cylinder is driven to move, so that the piston rod of the vertical cylinder moves downward, thereby causing the finger cylinders to move down and drive the stator cores clamped on the finger cylinders to move down, so that the stator cores are clamped on the positioning fixtures. After they are in place, the finger cylinders are released, and the control system drives the forward and backward moving mechanism to move the multi-station synchronous transport device backward. After they are in place, the left and right traction cylinders are driven to reset, and the transport components on the multi-station synchronous transport device return to their initial positions.
[0027] Repeating steps (2) to (4) enables continuous handling of the stator core on the production line.
[0028] Preferably, in the post-processing and waiting phase of step (2), the online self-maintenance cleaner is also activated, so that the compressed air sprayed from the pneumatic blow nozzle located below the finger cylinder is directed to the inner clamping part of the mechanical finger clamp of the finger cylinder for blow cleaning operation, and the pneumatic blow nozzle is closed after cleaning.
[0029] The beneficial effects of this utility model are:
[0030] First, the stator core multi-station synchronous handling device of this utility model, by setting synchronously moving handling components at equal intervals, can perfectly match the stator core production line, realize synchronous feeding, synchronous picking and synchronous transfer of stator cores on the production line, improve the automation level of the stator core production line, and thus improve the working efficiency of the stator core production line.
[0031] Secondly, the stator core multi-station synchronous handling device of this utility model is equipped with an online self-maintenance cleaner. This online self-maintenance cleaner utilizes the idle time of the multi-station synchronous handling device during the stator core post-processing on the production line to perform pneumatic blowing and cleaning of the finger cylinders. It can prevent dirt from contaminating the workpiece (stator core) and avoid the disadvantage of reduced workpiece loading and unloading position accuracy caused by dirt remaining on the mechanical gripper fingers, thereby improving the working reliability of the stator core post-processing production line.

The compressed air jet direction of the pair of pneumatic blowing nozzles 018 is respectively directed upward obliquely towards the pair of mechanical gripper fingers 016 on the finger cylinders 007.
[0050] By setting pneumatic cleaning nozzles 018 on the elongated substrate 003, when the synchronous conveying device is in the idle state of workpiece conveying (no workpiece is clamped on it), a pair of pneumatic cleaning nozzles 018 can be opened in a timely manner to pneumatically clean the mechanical gripping fingers 016 of the finger cylinder 007, preventing dirt from contaminating the workpiece (stator core 001), and avoiding the disadvantage of reduced workpiece loading and unloading position accuracy caused by dirt remaining on the mechanical gripping fingers 016, thereby improving the working reliability of the stator core post-processing production line.

[0052] In this embodiment, the multi-station synchronous handling device is an N-station synchronous handling device, and the number of the handling components supporting the N-station synchronous handling device is N - 1. In the figure, there are seven handling components supporting the eight-station synchronous handling device.
[0053] A stator core multi-station synchronous handling device in this embodiment further includes a control system, which automatically controls the actions of various functional components (including the finger cylinder 007, the vertical cylinder 008, the left and right traction cylinders 020, the front and back traction cylinders 020, and the pneumatic purging nozzle 018).
[0054] This embodiment can be matched with a stator core post-processing production line to achieve synchronous handling of stator cores 001 at multiple stations on the production line. It is required that the post-processing stations on the stator core post-processing production line are arranged in a straight line at equal intervals in sequence, and the station spacing is equal to the spacing of the handling components 004. At the same time, the multi-station synchronous handling device is arranged adjacent to the stator core post-processing production line, and the positions of the handling components 004 on the multi-station synchronous handling device correspond one by one to the positions of the post-processing stations on the stator core post-processing production line. The working principle of the stator core multi-station synchronous handling device for synchronous handling is as follows:
[0055] (1) Loading: The multi-station synchronous handling device grabs the stator core 001 from the first loading station through the control system, and then uses the left and right traction cylinders 013 to send the grabbed stator core 001 to the next station on the production line and position the stator core 001 on the positioning fixture at this station; as the loading proceeds rhythmically, the stator cores 001 that need corresponding post-processing are finally loaded at each station on the stator core post-processing production line;
[0056] (2) Post-processing and waiting: According to the working rhythm of the stator core post-processing production line, during the corresponding post-processing of the stator core 001 at each station, the multi-station synchronous handling device is in a waiting state; in the waiting state, the mechanical fingers 016 of the finger cylinders 007 in the stator core multi-station synchronous handling device are in a released state;
[0057] (3) Picking up parts: Once the post-processing tasks of the stator core 001 at each station are completed, the multi-station synchronous transport device is immediately started. The control system drives the multi-station synchronous transport device to move forward through the forward and backward moving mechanism 019, so that the finger cylinder 007 on the transport component 004 reaches the picking position. Then, the mechanical gripper 016 of the finger cylinder 007 is driven to clamp the stator core 001 at the station. After it is in place, the vertical cylinder 008 is driven to move, so that the piston rod 022 of the vertical cylinder moves upward and the finger cylinder 007 moves upward, driving the stator core 001 clamped on the finger cylinder 007 to move upward, thereby disengaging from the positioning fixture at the station. After it is in place, the multi-station synchronous transport device is driven to move backward through the forward and backward moving mechanism 019 to realize the picking up of the stator core at each station.
[0058] (4) Transfer: The control system drives the left and right traction cylinders 013 to move, and the stator cores 001 clamped on each finger cylinder 007 are moved to the next station. Then, the gripped positioning cores 001 are sent forward by the forward and backward moving mechanism 019 until each stator core 001 is located above the positioning fixture of each station. After reaching the position, the vertical cylinder 008 is driven to move, so that the piston rod of the vertical cylinder 008 moves downward, thereby causing the finger cylinder 007 to move down, driving the stator cores 001 clamped on the finger cylinder 007 to move down, so that the stator cores 001 are clamped on the positioning fixture. After reaching the position, the finger cylinder 007 is released, and the control system drives the forward and backward moving mechanism 019 to move, so that the multi-station synchronous transport device moves backward. After reaching the position, the left and right traction cylinders 013 are driven to reset, and each transport component 004 on the multi-station synchronous transport device returns to the initial position.
[0059] Repeating steps (2) to (4) can achieve continuous handling of stator core 001 on the production line.
[0060] Preferably, in the post-processing and waiting phase of step (2), the online self-maintenance cleaner is also activated, so that the compressed air ejected from the pneumatic blow nozzle 018 located below the finger cylinder 007 is directed to the inner clamping part of the mechanical finger clamp 016 of the finger cylinder 007 for blow cleaning operation, and the pneumatic blow nozzle is closed after cleaning.
[0061] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
