Description

Technical Field

[0001] This utility model relates to the field of frequency converter assembly technology, and specifically to an assembly device for frequency converter terminal blocks. Background Technology

[0002] A frequency converter (VDC) is a power electronic device used to change the power supply frequency of an AC motor, thereby achieving precise control of operating parameters such as motor speed and torque. The basic principle of a VDC is to convert AC power to DC power through a rectifier, and then convert the DC power back to AC power with a variable frequency through an inverter to provide power to the motor. By changing the frequency of the output AC power, the motor speed can be changed. The VDC terminal block is the interface component connecting the VDC to external devices. It uses various types of terminals to realize functions such as power input, motor connection, control signal transmission, and parameter setting. According to terminal type, there are high-voltage terminals and low-voltage terminals. The VDC terminal block assembly device is mainly used to accurately position and fix the terminal block in the corresponding position on the VDC, ensuring its secure installation and facilitating subsequent connection of other components. The assembly device first needs to transport the material box containing the terminal block assembly via a conveyor belt until the material box moves to the assembly assembly position, where a robot picks up the assembly components and performs subsequent assembly.

[0003] CN111644840B discloses an automatic assembly device for inverter terminals and retaining rings. It solves the problem of difficult assembly of inverter glass terminals and retaining rings in existing technologies. This automatic assembly device for inverter terminals and retaining rings includes an end cap conveying device, a retaining ring feeding device, and a feeding robot. The end cap conveying device includes a conveyor belt, along which a jig tray is conveyed. The jig tray has end cap positioning holes, and a terminal lifting part is provided below the jig tray corresponding to the terminal mounting holes of the end cap. Positioning holes are provided at the bottom of the jig tray. A support plate is fixedly connected to a base plate via a lower hanging rod located below the support plate. A material column turntable is provided under the base plate. This invention designs a set of automated mechanical equipment based on the structural and installation characteristics of inverter terminals and retaining rings, realizing the automation of terminal and retaining ring feeding, assembly, and inspection, thus improving efficiency and quality.

[0004] While existing technology CN111644840B offers numerous advantages during use, it still suffers from the following issues: its stability in transporting the material box is not adequate. To ensure stable transport of the material box, the existing conveyor belt only contacts the lower end of the material box with the conveyor belt. However, the conveyor belt vibrates during motor-driven operation, causing the material box to shift position. This affects the positioning accuracy of the subsequent assembly equipment and hinders the assembly equipment from properly positioning and assembling the material box. Utility Model Content

[0005] In view of the problems in the prior art, this utility model provides an assembly device for inverter terminal blocks.

[0006] The technical solution adopted by this utility model to solve its technical problem is an assembly device for inverter terminal boards, including a frame, a clamping plate, a fixing frame, and a support frame. Equally spaced parallel rollers are rotatably installed on both sides of the inner wall of the frame. A first conveyor belt is sleeved on the outer side of the rollers. A drive wheel is pinned to one end of the outer wall of the rollers through the frame. A clamping plate is provided on the upper outer wall of the first conveyor belt. Guide rods are welded to both outer walls of the clamping plate. Drive rollers are rotatably installed on both sides of the inner wall of the clamping plate. A second conveyor belt is sleeved on the outer wall of the drive rollers. A first conical tooth is pinned to one end of the outer wall of the clamping plate through the drive rollers. Support frames are screwed to both outer walls of the frame. A rotating shaft is rotatably installed inside the support frame. Fixing frames are symmetrically screwed to both outer walls of the frame. A limit groove is formed on one outer wall of the fixing frame.

[0007] By adopting the above technical solution, after the worker places the material box on the upper end of the first conveyor belt, the roller and the first conveyor belt can realize the horizontal transport of the material box. The drive roller in the clamping plate and the second conveyor belt can further position, clamp and transport the material box carrying the terminal board on both sides, ensuring the stability of the material box's trajectory during the transport process, ensuring the accuracy of the subsequent positioning of the material box, facilitating the positioning and assembly of the material box by the assembly device, reducing the equipment failure rate, improving the processing efficiency of the terminal board by the assembly device, and the clamping plate can be adjusted by the guide rod, thereby adjusting the distance between the two clamping plates to ensure that the distance between the two clamping plates can adapt to material boxes of different sizes, improving the applicability and flexibility of the device.

[0008] Specifically, assembly frames are welded to both sides of the lower outer wall of the frame, and drive motors are screwed to the lower ends of both sides of the outer wall of the frame. The drive motors are connected to the drive wheels by pins.

[0009] By adopting the above technical solution, the drive motor provides power to the drive wheel, and the pin connection ensures the stability and reliability of power transmission. It can also transmit power to the roller, driving the first conveyor belt to stably transport the material box, which helps to ensure assembly efficiency.

[0010] Specifically, a support plate for providing support is screwed to one side of the inner wall of the clamping plate. The support plate is located inside the second conveyor belt and does not contact the drive roller.

[0011] By adopting the above technical solution, the support plate provides internal support for the second conveyor belt, enabling it to maintain a stable shape and tension when conveying the terminal block, preventing the second conveyor belt from deforming or being damaged due to uneven force, and ensuring the contact area between the second conveyor belt and the material box, thus ensuring the stability and smoothness of the second conveyor belt conveying the material box. The support plate will not interfere with the rotation of the drive roller.

[0012] Specifically, a second conical tooth is connected to the outer wall of one end of the rotating shaft by a pin. The second conical tooth has the same number of teeth as the first conical tooth, and the second conical tooth meshes with the first conical tooth.

[0013] By adopting the above technical solution, the combination of the first conical tooth and the second conical tooth can effectively transmit power. Since the number of teeth is the same, the first conical tooth and the second conical tooth can be driven at the same speed, which can realize the precise transmission between the rotating shaft and the drive roller. This ensures that the movement of the second conveyor belt is coordinated and synchronized with the movement of the first conveyor belt, and ensures that the material box can be driven to move synchronously between the first conveyor belt and the second conveyor belt, thus ensuring the stability and smoothness of the material box's movement.

[0014] Specifically, a driven wheel is connected to the outer wall of one end of the rotating shaft by a pin. The outer wall size of the driven wheel is the same as that of the driving wheel. A transmission belt is sleeved on the outer side of the driven wheel. The other end of the transmission belt is sleeved on the outer side of the driving wheel, and the driven wheel is connected to the driving wheel through the transmission belt.

[0015] By adopting the above technical solution, the synchronous rotation of the shaft and the roller can be achieved through the transmission belt connection, ensuring that the conveying speed of the second conveyor belt is precisely matched with that of the first conveyor belt, ensuring the positioning accuracy of the material box during the assembly process. Furthermore, since the length of the driven wheel is greater than that of the driving wheel, the driven wheel can still be connected to the driving wheel through the transmission belt in different positions of the clamping plate, ensuring stable power transmission.

[0016] Specifically, the guide rod is smaller than the limit groove, and the guide rod is located inside the limit groove. A fastening bolt is screwed to one side of the upper end of the inner wall of the limit groove, and the fastening bolt passes through the limit groove and contacts the outer wall of the guide rod.

[0017] By adopting the above technical solution, the guide rod moves within the limiting groove, which can precisely limit the movement direction and position of the clamping plate, ensuring that it will not deviate during the position adjustment process. By tightening the fastening bolts, the position of the guide rod within the limiting groove can be adjusted according to actual needs, thereby adjusting the spacing between the clamping plates to adapt to material boxes of different sizes or assembly requirements, thus improving the versatility and flexibility of the device.

[0018] The beneficial effects of this utility model are:

[0019] (1) The assembly device for inverter terminal blocks described in this utility model ensures the stability of the material box's trajectory during the conveying process, guarantees the accuracy of the subsequent positioning of the material box, facilitates the positioning and assembly of the material box by the assembly device, reduces the equipment failure rate, and improves the processing efficiency of the terminal block by the assembly device.

[0020] (2) The assembly device for inverter terminal board described in this utility model can adjust the clamping plate through the guide rod, thereby adjusting the distance between the two clamping plates to ensure that the distance between the two clamping plates can adapt to material boxes of different sizes, thus improving the applicability and flexibility of the device.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the assembly device for inverter terminal blocks of this utility model includes a frame 1, a clamping plate 2, a fixing frame 3, and a support frame 4. Rollers 11 are rotatably mounted on both sides of the inner wall of the frame 1 at equal intervals. A first conveyor belt 12 is sleeved on the outer side of the rollers 11. A drive wheel 14 is pinned to one end of the outer wall of the rollers 11. A clamping plate 2 is provided on the upper outer wall of the first conveyor belt 12. Guide rods 21 are welded to both outer walls of the clamping plate 2. Drive rollers 22 are rotatably mounted on both sides of the inner wall of the clamping plate 2. A second conveyor belt 23 is sleeved on the outer wall of the drive rollers 22. A first conical tooth 25 is pinned to one end of the outer wall of the clamping plate 2. The support frame 4 is screwed to both outer walls of the frame 1. A rotating shaft 41 is rotatably mounted inside the support frame 4. The fixing frame 3 is symmetrically screwed to both outer walls of the frame 1. A limit groove 31 is opened on one side of the outer wall of the fixing frame 3.

[0030] In use, after the operator places the material box on the upper end of the first conveyor belt 12, the roller 11 and the first conveyor belt 12 can realize the horizontal transport of the material box. The drive roller 22 and the second conveyor belt 23 in the clamping plate 2 can further position, clamp and transport the material box carrying the terminal board on both sides, ensuring the stability of the material box's trajectory during the transport process, ensuring the accuracy of the subsequent positioning of the material box, facilitating the positioning and assembly of the material box by the assembly device, reducing the equipment failure rate, improving the processing efficiency of the terminal board by the assembly device, and the clamping plate 2 can be adjusted by the guide rod 21, thereby adjusting the distance between the two clamping plates 2 to ensure that the distance between the two clamping plates 2 can adapt to material boxes of different sizes, improving the applicability and flexibility of the device.

[0031] To drive rotation, for example, such as Figure 2 As shown, assembly brackets 13 are welded to both sides of the lower outer wall of frame 1, and drive motors 15 are screwed to the lower ends of both sides of the outer wall of frame 1. The drive motors 15 are connected to the drive wheel 14 by pins.

[0032] In use, the drive motor 15 provides power to the drive wheel 14. The connection through the pin shaft ensures the stability and reliability of the power transmission, and can transmit the power to the roller 11 to drive the first conveyor belt 12 to stably transport the material box, which helps to ensure assembly efficiency.

[0033] To support mobility, for example, such as Figure 4 As shown, a support plate 24 for providing support is screwed to one side of the inner wall of the clamping plate 2. The support plate 24 is located inside the second conveyor belt 23 and does not contact the drive roller 22.

[0034] During use, the support plate 24 provides internal support for the second conveyor belt 23, enabling it to maintain a stable shape and tension when conveying terminal plates, preventing the second conveyor belt 23 from deforming or being damaged due to uneven force, and ensuring the contact area between the second conveyor belt 23 and the material box, thus ensuring the stability and smoothness of the conveying of the material box by the second conveyor belt 23. The support plate 24 will not interfere with the rotation of the drive roller 22.

[0035] For synchronized rotation, for example, such as Figure 4 As shown, a second conical tooth 42 is pin-connected to the outer wall of one end of the rotating shaft 41. The number of teeth of the second conical tooth 42 is the same as that of the first conical tooth 25, and the second conical tooth 42 meshes with the first conical tooth 25.

[0036] In use, the combination of the first conical tooth 25 and the second conical tooth 42 can effectively transmit power. Since the number of teeth is the same, the first conical tooth 25 and the second conical tooth 42 can achieve the same speed transmission, which can realize the precise transmission between the rotating shaft 41 and the drive roller 22. This ensures that the movement of the second conveyor belt 23 is coordinated and synchronized with the movement of the first conveyor belt 12, and ensures that the material box can be driven to move synchronously between the first conveyor belt 12 and the second conveyor belt 23, thus ensuring the stability and smoothness of the material box's movement.

[0037] For synchronized rotation, for example, such as Figure 3 As shown, a driven wheel 43 is connected to the outer wall of one end of the rotating shaft 41 by a pin. The outer wall size of the driven wheel 43 is the same as that of the driving wheel 14. A transmission belt 44 is sleeved on the outer side of the driven wheel 43. The other end of the transmission belt 44 is sleeved on the outer side of the driving wheel 14, and the driven wheel 43 is connected to the driving wheel 14 through the transmission belt 44.

[0038] In use, the drive belt 44 enables the synchronous rotation of the shaft 41 and the roller 11, ensuring that the conveying speed of the second conveyor belt 23 is precisely matched with the conveying speed of the first conveyor belt 12, thus ensuring the positioning accuracy of the material box during assembly. Furthermore, since the length of the driven wheel 43 is greater than the length of the driving wheel 14, the clamping plate 2 can still ensure that the driven wheel 43 is connected to the driving wheel 14 through the drive belt 44 in different usage positions, thus ensuring stable power transmission.

[0039] To restrict the location of use, for example, such as Figure 5 As shown, the size of the guide rod 21 is smaller than the size of the limiting groove 31, and the guide rod 21 is located inside the limiting groove 31. A fastening bolt 32 is screwed to one side of the upper end of the inner wall of the limiting groove 31. The fastening bolt 32 passes through the limiting groove 31 and contacts the outer wall of the guide rod 21.

[0040] During use, the guide rod 21 moves within the limiting groove 31, which can precisely limit the movement direction and position of the clamping plate 2, ensuring that it will not deviate during position adjustment. By tightening the fastening bolt 32, the position of the guide rod 21 within the limiting groove 31 can be adjusted according to actual needs, thereby adjusting the spacing between the clamping plates 2 to adapt to material boxes of different sizes or assembly requirements, thus improving the versatility and flexibility of the device.

[0041] When using this utility model, the frame 1 is placed in a suitable working position and the position of the frame 1 is fixed by the assembly frame 13. The worker places the material box with the terminal plate on the upper end of the first conveyor belt 12, starts the drive motor 15, and the drive motor 15 transmits power to the drive wheel 14. The drive wheel 14 drives the roller 11 to rotate, thereby causing the first conveyor belt 12 sleeved on the outside of the roller 11 to run, so as to realize the horizontal transport of the material box.

[0042] According to the size of the material box, the worker loosens the fastening bolts 32 at the upper end of the inner wall of the limiting groove 31, pushes the clamping plate 2, and moves the guide rods 21 welded to the outer walls on both sides of the clamping plate 2 within the limiting groove 31, thereby adjusting the distance between the two clamping plates 2 to adapt to the size of the material box. After the adjustment is completed, the fastening bolts 32 are tightened so that the fastening bolts 32 contact the outer wall of the guide rods 21 to fix the position of the clamping plate 2. The second conveyor belt 23 positions and clamps the two sides of the material box and further conveys it.

[0043] During the conveying process, when the drive wheel 14 rotates under the drive of the drive motor 15, it drives the driven wheel 43 to rotate through the transmission belt 44 sleeved on the outside, which in turn drives the rotating shaft 41 to rotate. The first conical tooth 25 and the second conical tooth 42 mesh, and the two have the same number of teeth, so as to achieve the same speed transmission. This ensures that the movement of the second conveyor belt 23 is coordinated and synchronized with the movement of the first conveyor belt 12, and ensures that the material box is driven to move synchronously between the first conveyor belt 12 and the second conveyor belt 23.

[0044] It should be noted that this utility model is an assembly device for inverter terminal blocks.
