Description

Technical Field

[0001] This application relates to the field of relay assembly technology, and in particular to an SLA automatic assembly device for moving spring assemblies. Background Technology

[0002] Existing relays include a frame and a moving spring. The frame has a yoke with a rivet post. The moving spring has a mounting hole that matches the rivet post. During the production and assembly of the relay, the moving spring needs to be assembled and riveted to the yoke on the frame.

[0003] Currently, the moving spring is riveted together with the armature and moving contact to form a moving spring assembly, and the frame, coil and yoke are combined to form a coil assembly, and then the two are assembled.

[0004] Regarding the aforementioned technologies, the inventors believe that the current installation of the moving spring assembly and coil assembly is done manually, which greatly increases labor costs and results in low processing efficiency. Utility Model Content

[0005] The purpose of this application is to provide an SLA automatic assembly device for moving spring assemblies, in order to improve the problem that the installation of moving spring assemblies and coil assemblies is currently done manually, which greatly increases labor costs and results in low processing efficiency.

[0006] The SLA automatic assembly spring assembly device provided in this application adopts the following technical solution: The SLA automatic assembly device for moving spring assemblies includes a base, a receiving seat for placing coil assemblies slidably disposed on the base, a drive assembly for moving the receiving seat on the base, the drive assembly including a synchronous pulley rotatably disposed on the base and a synchronous belt adapted to the synchronous pulley, a drive motor for driving the synchronous pulley to rotate disposed below the base, and the receiving seat connected to the synchronous belt; a gripper cylinder for clamping the moving spring assembly is disposed above the receiving seat, a support frame is disposed on the base near the receiving seat, and a transfer assembly corresponding to the gripper cylinder is disposed above the support frame, the transfer assembly driving the gripper cylinder to clamp the moving spring assembly to the position of the coil assembly for assembly.

[0007] By adopting the above technical solution, the receiving seat is connected to the synchronous belt. The movement of the synchronous belt drives the receiving seat to move, and the receiving seat brings the coil assembly to the position corresponding to the gripper cylinder. The moving component on the support frame enables the gripper cylinder to clamp the moving spring assembly to the position of the coil assembly for assembly, saving manpower and improving the assembly efficiency of the moving spring assembly.

[0008] Optionally, the base is provided with a guide rail that is slidably connected to the support seat below the support seat. The guide rail corresponds to the timing belt. Several rotating wheels that fit against the side wall of the guide rail are rotatably arranged below the support seat.

[0009] By adopting the above technical solution, a rotating wheel 1, which is rotatably mounted below the receiving seat and is in contact with the side walls of several guide rails, moves the receiving seat when the synchronous belt drives it to move. This reduces the possibility of the receiving seat getting stuck when the guide rail is located at the arc position of the synchronous belt, and minimizes the possibility of the receiving seat getting stuck due to sliding connection between the receiving seat and the guide rail through the groove.

[0010] Optionally, the upper part of the receiving seat is provided with a mounting groove that fits with the coil assembly, and the inner side wall of the mounting groove is provided with a fixing groove that fits with the pins of the coil assembly.

[0011] By adopting the above technical solution, an installation groove that fits with the coil assembly is provided above the receiving seat, and a fixing groove that fits with the pins of the coil assembly is provided on the inner side wall of the installation groove, so that the coil assembly can be better fixed on the receiving seat, reducing the possibility of the coil assembly detaching when the receiving seat moves, and reducing the damage to the pins when the moving spring assembly and the coil assembly are assembled.

[0012] Optionally, the receiving seat is provided with a connecting frame on the side near the timing belt, the connecting frame is provided with a fixing rod on the inner side of the timing belt, the timing pulley is provided with a groove corresponding to the fixing rod, and the receiving seat is provided with several evenly spaced on the timing belt.

[0013] By adopting the above technical solution, the timing belt is engaged and fixed between the fixing rod and the connecting frame by the fixing rod of the connecting frame, thereby fixing the connecting frame; a groove corresponding to the fixing rod is opened on the timing pulley, so that the timing pulley can engage with the fixing rod when rotating, reducing the possibility of damage to the timing pulley caused by the collision between the teeth on the fixing rod and the timing pulley.

[0014] Optionally, the transfer assembly includes a movable frame slidably connected to a support frame. One end of the support frame is provided with a drive component one for driving the movable frame to move toward the receiving seat. A mounting frame fixedly connected to a gripper cylinder is slidably provided on the side of the movable frame away from the support frame. A drive component two for driving the mounting frame to slide up and down is provided above the movable frame.

[0015] By adopting the above technical solution, the driving end of the driving cylinder pushes the moving frame to move towards the receiving seat, and the driving end of the second driving component pushes the mounting frame to move vertically towards the receiving seat, so that the gripper cylinder moves to the position of the receiving seat when it picks up the moving spring assembly to assemble the moving spring assembly and the coil assembly. This facilitates the movement of the gripper cylinder to clamp the moving spring assembly and to move to the position of the receiving seat for assembly.

[0016] Optionally, the gripper cylinder has a limiting groove corresponding to the moving spring assembly at the gripper position near the moving spring assembly. A pressure rod is provided between the grippers below the gripper cylinder above the moving spring assembly. A rotating wheel two is rotatably provided at the end of the pressure rod and contacts the moving spring assembly. A moving block connected to the pressure rod is slidably provided on the side of the mounting frame away from the gripper cylinder. A driving component three is provided above the mounting frame to drive the moving block to move down. The driving component three drives the moving block and the pressure rod to move down, so that the rotating wheel two presses the moving spring in the moving spring assembly onto the yoke of the coil assembly.

[0017] By adopting the above technical solution, a limiting groove corresponding to the moving spring assembly is opened at the gripper position of the gripper cylinder near the moving spring assembly, so that when the gripper of the gripper cylinder clamps the moving spring assembly, the limiting groove contacts the side wall of the moving spring assembly, reducing the possibility of the moving spring assembly falling off; when the gripper cylinder moves the moving spring assembly to the coil assembly through the transfer assembly, the driving component three drives the moving block to move down, and the moving block moves down with the pressure rod, so that the rotating wheel two connected to the end of the bent part of the pressure rod abuts against the moving spring sheet in the moving spring assembly. When the moving spring sheet is pressed onto the yoke of the coil assembly, the rotating wheel two rotates at the end of the pressure rod during the pressing process, connecting the moving spring sheet to the riveting point on the yoke, preventing deformation of the forming size of the moving spring sheet.

[0018] Optionally, the support frame is provided with a driving component four, and the driving end of the driving component four is connected to a stop bar located on the side of the gripper cylinder near the driving assembly. When the gripper cylinder clamps the moving spring assembly near the coil assembly for assembly, the driving component four drives the stop bar to abut against the coil assembly.

[0019] By adopting the above technical solution, a stop bar is set at the driving end of the driving component four on the side of the gripper cylinder near the driving assembly. When the gripper cylinder clamps the moving spring assembly close to the coil assembly for assembly, the driving stop bar of the driving component four abuts against the coil assembly. When the moving spring assembly is in contact with the coil assembly, the driving component one should be kept away from the receiving seat as much as possible to avoid the gripper cylinder applying a horizontal force to the moving spring assembly to complete the assembly.

[0020] Optionally, a pad is provided on the base below the gripper cylinder and at a position away from the guide rail. The pad abuts against the bottom of the support and the two ends of the pad are inclined.

[0021] By adopting the above technical solution, a pad is fixed at a position where the base is located below the gripper cylinder and away from the guide rail. The pad abuts against the bottom of the support, so as to avoid the possibility of the support tilting when the moving spring assembly and the coil assembly are pressed together. The two ends of the pad are set with bevels, so that the support can move above the pad with the synchronous belt.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. A rotating wheel, which is rotatably mounted below the receiving seat and is in contact with the side walls of several guide rails, moves the receiving seat when the synchronous belt drives it to move. This reduces the possibility of the receiving seat getting stuck when the guide rail is located at the arc position of the synchronous belt, and minimizes the possibility of the receiving seat getting stuck due to sliding connection between the receiving seat and the guide rail through the groove. 2. An installation groove is provided above the receiving seat to fit the coil assembly, and a fixing groove is provided on the inner side wall of the installation groove to fit the pins of the coil assembly, so that the coil assembly can be better fixed on the receiving seat, reducing the possibility of the coil assembly detaching when the receiving seat moves, and reducing the damage to the pins when the moving spring assembly and the coil assembly are assembled. 3. A limiting groove corresponding to the moving spring assembly is provided at the gripper position of the gripper cylinder near the moving spring assembly. This allows the gripper of the gripper cylinder to contact the side wall of the moving spring assembly through the limiting groove when gripping the moving spring assembly, reducing the possibility of the moving spring assembly falling off. When the gripper cylinder moves the moving spring assembly onto the coil assembly through the transfer assembly, the driving component three drives the moving block to move downward. The moving block moves the pressure rod downward, causing the rotating wheel two, which is rotatably connected to the end of the bent part of the pressure rod, to abut against the moving spring sheet in the moving spring assembly. When the moving spring sheet is pressed onto the yoke of the coil assembly, the rotating wheel two rotates at the end of the pressure rod during the pressing process, connecting the moving spring sheet to the riveting point on the yoke, preventing deformation of the forming dimensions of the moving spring sheet.

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0042] SLA automatic assembly spring assembly device, refer to Figure 1 and Figure 3The system includes a base 1, a receiving seat 2 for placing the coil assembly 4 slidably disposed on the base 1, a driving assembly 3 disposed on the base 1, the driving assembly 3 including a synchronous pulley 31 rotatably mounted on the base 1 via a rear bearing, and a synchronous belt 32 adapted to the synchronous pulley 31. The synchronous pulley 31 is a synchronous gear, and the synchronous belt 32 is a synchronous toothed belt. A drive motor (not shown in the figure) that drives the synchronous pulley 31 to rotate is bolted to the base 1 and is electrically connected to a power source. The receiving seat 2 is connected to the synchronous belt 32, and the movement of the synchronous belt 32 drives the receiving seat 2 to move. A gripper cylinder 6 for holding the moving spring assembly 5 is disposed above the receiving seat 2. A support frame 7 is bolted to the base 1 near the receiving seat 2. A transfer assembly 8 corresponding to the gripper cylinder 6 is disposed above the support frame 7. The transfer assembly 8 drives the gripper cylinder 6 to hold the moving spring assembly 5 and move it to the position of the coil assembly 4 for assembly.

[0043] Reference Figure 1 and Figure 2 A guide rail 33, which is slidably connected to the support seat 2, is bolted to the base 1 below the support seat 2. The guide rail 33 corresponds to the timing belt 32. Several rotating wheels 22, which are in contact with the side wall of the guide rail 33, are rotatably connected to the support seat 2 below the support seat 2 by a rotating shaft. When the timing belt 32 moves the support seat 2, the rotation of the rotating wheels 22 in contact with the side wall of the guide rail 33 reduces the possibility of the support seat 2 getting stuck when the guide rail 33 is located at the arc position of the timing belt 32. A connecting rod is welded to the side of the support seat 2 near the timing belt 32. The connecting frame 23 has a fixing rod 24 inserted inside the synchronous belt 32, so that the synchronous belt 32 is engaged and fixed between the fixing rod 24 and the connecting frame 23, thus fixing the connecting frame 23. The synchronous pulley 31 has a groove 311 corresponding to the fixing rod 24. The receiving seat 2 is evenly spaced on the synchronous belt 32 so that the synchronous pulley 31 can engage with the fixing rod 24 when rotating, reducing the possibility of damage to the synchronous pulley 31 due to the collision between the fixing rod 24 and the teeth on the synchronous pulley 31.

[0044] Reference Figure 1 and Figure 3The transfer assembly 8 includes a movable frame 81 slidably connected to the support frame 7 via a slide rail fixed on the support frame 7. A drive component 82, electrically connected to a power source, is bolted to one end of the support frame 7 to drive the movable frame 81 horizontally towards the receiving seat 2. The drive component 82 pushes the movable frame 81 towards the receiving seat 2. A mounting frame 83, electrically connected to a gripper cylinder 6, is slidably disposed on the side of the movable frame 81 away from the support frame 7. The gripper cylinder 6 is also electrically connected to a power source. The mounting frame 83 is slidably connected to the movable frame 81 and fixedly connected to the movable frame 81. The frame 81 is slidably connected to the slide rail fixed on the movable frame 81. The mounting frame 83 is bolted to the gripper cylinder 6 on the side near the receiving seat 2. A second driving component 84 is bolted on the upper part of the movable frame 81 to drive the mounting frame 83 to slide up and down. The second driving component 84 is also a driving cylinder electrically connected to the power supply. The driving end of the second driving component 84 pushes the mounting frame 83 to move vertically towards the receiving seat 2, so that the gripper cylinder 6 can move to the position of the receiving seat 2 when it picks up the moving spring assembly 5 to assemble the moving spring assembly 5 and the coil assembly 4.

[0045] Reference Figure 1 , Figure 2 and Figure 3 A limiting groove 61 corresponding to the moving spring assembly 5 is provided at the gripper position of the gripper cylinder 6 near the gripper of the moving spring assembly 5, so that when the gripper of the gripper cylinder 6 clamps the moving spring assembly 5, the limiting groove 61 contacts the side wall of the moving spring assembly 5, reducing the possibility of the moving spring assembly 5 falling off; a pressure rod 85 is provided between the grippers below the gripper cylinder 6 and above the moving spring assembly 5, and a rotating wheel 851 that contacts the moving spring assembly 5 is rotatably connected to the end of the pressure rod 85 via a rotating shaft and bearing; a sliding rail is provided on the side of the mounting bracket 83 away from the gripper cylinder 6 to the pressure rod 85. The movable block 86 connected to the rod 85 is bolted above the mounting bracket 83 to drive the moving block 86 to move downward. When the gripper cylinder 6 moves the moving spring assembly 5 to the coil assembly 4 through the transfer assembly 8, the drive member 87 drives the pressure rod 85 to move downward. The rotating wheel 851 connected to the end of the bent part of the pressure rod 85 abuts against the moving spring in the moving spring assembly 5. When the moving spring is pressed onto the yoke of the coil assembly 4, the rotating wheel 851 rotates at the end of the pressure rod 85 during the pressing process, connecting the moving spring to the rivet point on the yoke.

[0046] Reference Figure 2 and Figure 3The drive component 71 is fixed to the side wall of the support frame 7 by bolts. The drive component 71 is a double-headed cylinder that is electrically connected to the power supply. The drive end of the drive component 71 is connected to the stop rod 72 by bolts on the side of the gripper cylinder 6 near the drive assembly 3. When the gripper cylinder 6 clamps the moving spring assembly 5 close to the coil assembly 4 for assembly, the drive component 71 drives the stop rod 72 to abut against the coil assembly 4. When the moving spring assembly 5 is in contact with the coil assembly 4, the drive component 82 should be prevented from pushing the moving frame 81 to make the gripper cylinder 6 apply a horizontal force to the moving spring assembly 5 to complete the assembly and the coil assembly 4 leaves the support seat 2.

[0047] Reference Figure 1 , Figure 2 and Figure 3 An mounting groove 21 is provided above the receiving seat 2 to fit the coil assembly 4. A fixing groove 211 is provided on the inner side wall of the mounting groove 21 to fit the pins of the coil assembly 4, so that the coil assembly 4 can be better fixed on the receiving seat 2 and reduce the possibility of the coil assembly 4 detaching when the receiving seat 2 moves. A pad 12 is bolted to the base 1 below the gripper cylinder 6 and at a position on the receiving seat 2 away from the guide rail 33. The pad 12 abuts against the bottom of the receiving seat 2 to avoid the possibility of the receiving seat 2 tilting when the moving spring assembly 5 and the coil assembly 4 are pressed together. The two ends of the pad 12 are set with bevels to facilitate the receiving seat 2 to move above the pad 12 with the synchronous belt 32.

[0048] The implementation principle of this application embodiment is as follows: In actual operation, the coil assembly 4 is placed in the mounting slot 21 on the receiving seat 2, so that the pins of the coil assembly 4 are located in the fixing slot 211 of the receiving seat 2. The synchronous pulley 31 is driven by the drive motor to rotate, so that the synchronous belt 32 carries the receiving seat 2 along the guide rail 33 to the position of the pad 12, and the pad 12 supports the receiving seat 2. The drive component 82 on the support frame 7 drives the moving frame 81 to move horizontally toward the receiving seat 2, and the drive component 84 on the moving frame 81 drives the mounting frame 83 to move vertically toward the receiving seat 2, so that the gripper cylinder 6 clamps the moving spring assembly 5 and moves it toward the receiving seat 2. When the moving spring assembly 5 contacts the coil assembly 4, the drive end of the drive component 71 drives the stop rod 72 to contact the coil assembly. When the gripper cylinder 6 holds the moving spring assembly 5 close to the coil assembly 4 for assembly, the drive component 4 71 drives the stop rod 72 to abut against the coil assembly 4. The drive component 1 82 pushes the moving frame 81 so that the gripper cylinder 6 applies a horizontal force to the moving spring assembly 5 to complete the assembly. At the same time, the drive component 3 87 on the mounting frame 83 drives the pressure rod 85 to press down. The rotating wheel 2 851 at the end of the pressure rod 85 connects the moving spring of the moving spring assembly 5 to the riveting point on the yoke of the coil assembly 4, assembling the moving spring assembly 5 and the coil assembly 4. Then, the synchronous belt 32 moves the receiving seat 2 to the subsequent station for riveting and fixing, and then the assembled relay is taken out, saving manpower and improving the assembly efficiency of the moving spring assembly 5.
