Description

Technical Field

[0001] The utility model relates to the technical field of bus duct production line equipment, in particular to a bus duct blanking and fixing structure. Background Art

[0002] During the production process of bus duct, the bus duct needs to be transported. At present, the conveying equipment mainly uses a linked roller conveying structure. This structure consists of multiple rollers, which are driven continuously or synchronously to achieve material movement. In order to ensure the stability of the bus duct during the conveying process, a clamp is required to clamp it. The clamp is generally set at the upper end of the conveying equipment in a sliding form through a slide rail and a slider. During the conveying process, the clamp moves to the next process position together with the product. After the product is conveyed, the clamp returns to its initial position.

[0003] The current technical problems are: Since the bus duct copper busbar itself is made of a relatively soft material, it is easily deformed by pressure, especially when the clamping force is not properly controlled during the clamping process. For example, when the clamping force is too large, the copper busbar is deformed by pressure, and when the clamping force is too small, it cannot achieve a good fixing effect on the copper busbar. Therefore, it is necessary to improve the clamp. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a busbar blanking and fixing structure to solve the technical problem that the existing busbar blanking and fixing structure easily causes the copper busbar to deform when clamping the copper busbar.

[0005] Based on the above objectives, the utility model provides a bus duct blanking and fixing structure, comprising:

[0010] A controller for controlling the drive assembly, the controller being electrically connected to the photoelectric switch,

[0011] The blocking member is used to cut off the light path. When the clamping plate and the push plate overcome the elastic force and move close to a specified distance, the blocking member opens or cuts off the light path to change the photoelectric switch component, thereby controlling the driving component to stop.

[0012] As a preferred technical solution of the present invention, the driving assembly includes a cylinder connected to the frame, the output end of the driving assembly is the piston rod of the cylinder, and the piston rod is connected to the push plate.

[0020] As a preferred technical solution of the present invention, sliders are provided on both sides of the frame, and the sliders are slidably connected to slide rails.

[0021] The beneficial effects of the present invention are as follows: the present invention provides a push plate at the output end of the driving component, connects the push plate and the clamping plate in an elastic manner, and provides a photoelectric switch component and a blocking member between the two, so that when the force exerted by the busbar copper bar on the clamping plate exceeds the elastic force between the push plate and the clamping plate, the push plate and the clamping plate move closer to each other, thereby driving the blocking member to move to the optical path between the light beam emitting end and the light beam receiving end, cutting off the transmission of the light beam, so that the photoelectric switch component transmits a signal to the controller to stop the driving component, thereby preventing the busbar copper bar from being damaged due to excessive clamping force.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs. The "first", "second" and similar words used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0030] like Figure 1 As shown, a busbar blanking and fixing structure comprises: a frame 1 and at least two clamping plates 2 provided on the frame 1; a driving assembly for driving the clamping plates 2 to move toward or away from each other; a push plate 8 connected to the output end of the driving assembly, the push plate 8 being elastically connected to the clamping plates 2; a photoelectric switch assembly provided between the push plate 8 and the clamping plates 2, the photoelectric switch assembly having a light beam emitting end and a light beam receiving end, wherein a light path is formed between the light beam emitting end and the light beam receiving end; a controller for controlling the driving assembly, the controller being electrically connected to the photoelectric switch, and a blocking member for cutting off the light path. When the clamping plates 2 and the push plate 8 overcome the elastic force and move toward each other to a specified distance, the blocking member switches on or off the light path, causing the photoelectric switch assembly to change, thereby controlling the driving assembly to stop.

[0031] The above technical solution can prevent the busbar copper busbar from being damaged due to excessive clamping force. When in use, the driving component is started to drive the two clamps 2 to move closer to each other, and the two clamps 2 fit the busbar copper busbar. The driving component continues to drive the clamps 2 to move closer to each other. At this time, the busbar copper busbar generates a reverse force on the clamps 2. When the force exceeds the elastic force between the push plate 8 and the clamps 2, the push plate 8 and the clamps 2 move closer to each other to shorten the distance, thereby driving the blocking member to move to the optical path between the light beam emitting end and the light beam receiving end, cutting off the transmission of the light beam, and the photoelectric switch component detects the object, which is then converted into an electrical signal to be input to the controller. The controller controls the driving component to stop, and at this time the clamps 2 stop moving closer to prevent the busbar copper busbar from being clamped and deformed.

[0032] like Figure 1 As shown, in this embodiment, sliders 22 are provided on both sides of the frame 1, and the sliders 22 are slidably connected to the slide rails 23;

[0033] The adoption of the above technical solution can ensure that the device can move on the conveying equipment together with the busbar copper bar. The slider 22 and the slide rail 23 can accurately guide the linear movement of the frame 1. The slide rail 23 is fixedly mounted on the conveying equipment. When the conveying equipment drives the busbar copper bar, the busbar copper bar will synchronously drive the device to move. The frame 1 can also be driven by a roller chain or other common power methods to achieve automatic return to the initial position when the busbar copper bar reaches the specified position, without the need for manual reset.

[0034] like Figure 2 As shown, in this embodiment, the driving assembly includes a cylinder 9 connected to the frame 1, and the output end of the driving assembly is the piston rod of the cylinder 9, which is connected to the push plate 8;

[0035] The above technical solution can drive the two splints 2 to move toward each other or in opposite directions.

[0036] like Figure 3As shown, in this embodiment, a plurality of guide posts 10 are provided on one side of the push plate 8, and the guide posts 10 are slidably engaged with the guide grooves 11 provided on the surface of the frame 1;

[0037] The above technical solution can improve the stability between the push plate 8 and the frame 1 and maintain the linear movement of the push plate 8.

[0038] like Figure 2 and Figure 4 As shown, in this embodiment, the photoelectric switch assembly includes a mirror-reflective photoelectric switch 12 and a reflector 13 provided on the side of the push plate 8 facing the clamping plate 2, and the blocking member is a light shielding plate 14 provided on the side of the clamping plate 2 facing the push plate 8;

[0039] The above technical solution can block the mirror-reflective photoelectric switch 12 between the reflector 13 through the shading plate 14, blocking the light path. In the initial state, the mirror-reflective photoelectric switch 12 emits a light beam to the reflector 13, and the reflector 13 reflects the light beam back to the mirror-reflective photoelectric switch 12, forming a complete light path. The piston rod of the cylinder 9 drives the clamps 2 to move closer to each other and fit the bus duct copper bar. When the reverse force of the bus duct copper bar on the clamp 2 exceeds the elastic force between the clamp 2 and the push plate 8, the clamp 2 moves toward the push plate 8, thereby prompting the shading plate 14 to move between the mirror-reflective photoelectric switch 12 and the reflector 13. The light beam of the mirror-reflective photoelectric switch 12 cannot be reflected back to itself. The mirror-reflective photoelectric switch 12 detects an obstacle and transmits it to the controller through an electrical signal, causing the controller to stop the cylinder 9 to prevent the clamping force of the clamp 2 from being too large and deforming the bus duct copper bar.

[0040] like Figure 2 As shown, in this embodiment, a limiting post 15 is provided on one side of the push plate 8, and the limiting post 15 is slidably engaged with a limiting groove 16 provided on the surface of the clamping plate 2, and a spring 19 is sleeved on the surface of the limiting post 15;

[0041] The above technical solution can elastically connect the splint 2 and the push plate 8. When the splint 2 is subjected to a reaction force, it will tend to move toward the push plate 8, thereby moving closer to the push plate 8 through the limit groove 16 and the limit column 15. When the reaction force is greater than the elastic force of the spring 19, the splint 2 moves toward the push plate 8, thereby driving the shading plate 14 to move between the mirror-reflective photoelectric switch 12 and the reflector 13.

[0042] like Figure 3 and Figure 4 As shown, in this embodiment, a first threaded column 17 and a second threaded column 20 are respectively provided at both ends of the limiting column 15. The first threaded column 17 passes through the limiting groove 16 and is threadedly connected to the first nut 18. The second threaded column 20 is fixedly connected to the push plate 8. The second threaded column 20 is threadedly connected to the second nut 21. The second threaded column 20 conflicts with one end of the spring 19.

[0043] The above technical solution can be used to adjust the elastic force of the spring 19, and the state of the spring 19 can be adjusted by rotating the second nut 21. When the second nut 21 squeezes the spring 19, it means that the clamping plate 2 will be subjected to a larger reaction force to overcome the elastic force and move toward the push plate 8. Conversely, when the second nut 21 is away from the spring 19, the clamping plate 2 only needs to be subjected to a reaction force lower than the standard size to overcome the elastic force and move toward the push plate 8, thereby adjusting the clamping force of the clamping plate 2 according to the busbar copper bars of different specifications.

[0044] like Figure 4 As shown, in this embodiment, the blanking and fixing structure further includes: a rubber pad 3 with a mounting block 4 on one side, the mounting block 4 cooperates with a mounting groove 5 provided on one side of the clamping plate 2, and the clamping plate 2 is penetrated by an internal thread groove 6; a fastening bolt 7 passes through the internal thread groove 6, and one end of the fastening bolt 7 abuts against the rubber pad 3;

[0045] The above technical solution can prevent the clamping plate 2 from damaging the busbar copper bar, and the provision of the rubber pad 3 can help keep the surface of the busbar copper bar from being damaged. At the same time, the rubber pad 3 can also be removed.

[0046] Working principle: In the initial state, the mirror-reflective photoelectric switch 12 emits a light beam to the reflector 13, and the reflector 13 reflects the light beam back to the mirror-reflective photoelectric switch 12, forming a complete light path. The piston rod of the cylinder 9 drives the clamps 2 to move closer to each other and fit the busbar copper bar. When the reverse force of the busbar copper bar on the clamp 2 exceeds the elastic force of the spring 19, the clamp 2 cooperates with the limit column 15 through the limit groove 16 to move closer to the push plate 8, thereby prompting the clamp 2 to drive the sunshade 14 to move between the mirror-reflective photoelectric switch 12 and the reflector 13. The light beam of the mirror-reflective photoelectric switch 12 cannot be reflected back to itself. The mirror-reflective photoelectric switch 12 detects an obstacle and transmits it to the controller through an electrical signal, causing the controller to stop the cylinder 9 to prevent the clamping force of the clamp 2 from being too large and deforming the busbar copper bar.
