Description
Technical Field
[0001] This application relates to the field of engine cylinder head assembly technology, and in particular to an automatic cylinder head wiping mechanism. Background Technology
[0002] Cylinder head wiping is a widely used operation on engine production lines. After the cylinder head is cleaned, there will be water stains and debris on the surface of the cylinder head, which need to be wiped clean. Only when the cylinder head is clean can it meet the requirements of fully automatic engine assembly. The automatic wiping mechanism is required to have a certain lifespan and be simple to operate and easy to maintain.
[0003] In existing technologies, cylinder heads are usually placed on a pallet and stopped on a roller conveyor, where they are wiped manually. However, manual wiping has drawbacks such as poor cleaning effect, high labor costs, and low efficiency, making it difficult to meet production needs and thus requiring improvement. Utility Model Content
[0004] In order to achieve the technical effect of automatic cylinder head wiping and improve the efficiency of cylinder head wiping, this application provides an automatic cylinder head wiping mechanism.
[0005] The automatic cylinder head wiping mechanism provided in this application adopts the following technical solution: An automatic cylinder head wiping mechanism includes a frame, on which a mounting base is fixedly installed. An unwinding mechanism, a wiping mechanism, and a rewinding mechanism are installed on the mounting base. The wiping mechanism is located between the unwinding mechanism and the rewinding mechanism, and is mounted above the unwinding mechanism and the rewinding mechanism. The wiping mechanism includes a bracket, a wiping roller, a first traction roller, and a second traction roller. The bracket is fixedly connected to the mounting base. The wiping roller and the first traction roller are both mounted on the bracket. The second traction roller is rotatably mounted on the mounting base. The wiping roller is located above the first traction roller and the second traction roller. The first traction roller is located on the side of the wiping roller closer to the unwinding mechanism, and the second traction roller is located on the side of the wiping roller closer to the winding mechanism. The mounting shafts at both ends of the wiping roller are connected to the bracket by an elastic connection structure.
[0006] By adopting the above technical solution, the unwinding mechanism and the rewinding mechanism are used to transport the non-woven fabric through the wiping mechanism. When the cylinder needs to be wiped clean, the robot grabs the cylinder cover and places it at the wiping mechanism. After the surface of the cylinder cover contacts the wiping mechanism, the robot continuously pushes the cylinder cover forward. Due to the elastic connection structure, the non-woven fabric wrapped on the wiping roller can contact the surface of the cylinder cover. The robot moves the cylinder cover, allowing the surface of the cylinder cover to pass over the non-woven fabric on the wiping roller at a uniform speed, achieving the technical effect of automatically wiping and cleaning the surface of the cylinder cover. After wiping is completed, the rewinding mechanism drives the non-woven fabric to move, which can bring clean non-woven fabric to wrap around the wiping roller. Because there is an elastic connection structure between the support and the wiping roller, the elasticity of the elastic connection structure can increase the contact pressure between the non-woven fabric and the cylinder cover, improving the cleanliness of the wiping cleaning.
[0007] Preferably, a support base is fixedly installed on the mounting base, and the bracket includes two vertical plates, both of which are bolted to the support base. The wiping roller and the first traction roller are installed between the two vertical plates. Both vertical plates are provided with first waist-shaped holes for the mounting shafts at both ends of the wiping roller to pass through. The elastic connection structure includes two first fixing seats, which are respectively bolted to the outside of the two vertical plates. A guide rod is fixedly installed on the first fixing seat, and a spring is coaxially sleeved on the guide rod. The end of the mounting shaft at the end of the wiping roller that extends out of the first waist-shaped hole is provided with a through hole for the guide rod to pass through. Both vertical plates have second oblong holes on their outer side walls for the mounting shafts at both ends of the first traction roller to pass through. Both vertical plates have second fixing seats fixedly installed on their outer side walls. A tension spring is fixedly installed on the second fixing seat. The end of the tension spring away from the second fixing seat is connected to the end of the mounting shaft of the first traction roller that extends out of the second oblong hole.
[0008] By adopting the above technical solution, during the wiping process, the spring compression generates elastic force, causing the non-woven fabric wrapped on the wiping roller to come into close contact with the surface of the cylinder cover. When the wiping roller is pressed down, the tension of the non-woven fabric decreases, the tension spring extends, and the first traction roller moves down, ensuring the stability of the non-woven fabric tension. In addition, through the first traction roller and the second traction roller, the non-woven fabric can be tightly wrapped around the roller body of the wiping roller.
[0009] Preferably, the unwinding mechanism includes an air shaft mounted on a mounting base and two limiting rollers. The two limiting rollers are located between the air shaft and the bracket. Each of the two limiting rollers includes two baffles. The distance between the two baffles is the same as the width of the nonwoven fabric, and a channel for the nonwoven fabric to pass through is formed between the two limiting rollers.
[0010] By adopting the above technical solution, the two limiting rollers can restrict the position of the nonwoven fabric, preventing the nonwoven fabric from shifting position.
[0011] Preferably, the winding mechanism includes a housing, a servo motor, and a winding roller. The winding roller is rotatably mounted on a mounting base. The housing is fixedly mounted on the side of the mounting base away from the winding roller. The mounting shaft at the end of the winding roller passes through the mounting base and extends into the housing. The servo motor is mounted on the outer wall of the housing, and the drive shaft end of the servo motor is connected to the mounting shaft of the winding roller extending into the housing via a coupling.
[0012] By adopting the above technical solution, the take-up roller can be driven to rotate by a servo motor, thereby driving the nonwoven fabric to move automatically.
[0013] Preferably, a first synchronous pulley and a second synchronous pulley are rotatably mounted inside the housing, and a synchronous belt is installed on the first synchronous pulley and the second synchronous pulley. The servo motor is connected to the first synchronous pulley through a coupling, and the second synchronous pulley is coaxially and fixedly connected to the end of the take-up roller that extends into the housing.
[0014] By adopting the above technical solution, and through the combination and use of the first synchronous pulley, the second synchronous pulley, and the synchronous belt, the technical effect of transmission connection between the servo motor and the mounting shaft at the end of the take-up roller can be achieved.
[0015] In summary, the cylinder head automatic wiping mechanism of this application has at least the following beneficial technical effects: 1. The unwinding and rewinding mechanisms are used to transport the non-woven fabric through the wiping mechanism. When the cylinder needs to be wiped clean, the robot grabs the cylinder cover and places it at the wiping mechanism. After the surface of the cylinder cover contacts the wiping mechanism, the robot continuously pushes the cylinder cover forward. Due to the elastic connection structure, the non-woven fabric wrapped on the wiping roller can contact the surface of the cylinder cover. The robot moves the cylinder cover, allowing the surface of the cylinder cover to pass over the non-woven fabric on the wiping roller at a uniform speed, achieving the technical effect of automatically wiping and cleaning the surface of the cylinder cover. After wiping, the rewinding mechanism drives the non-woven fabric to move, which can bring clean non-woven fabric to wrap around the wiping roller. Because there is an elastic connection structure between the support and the wiping roller, the elasticity of the elastic connection structure can increase the contact pressure between the non-woven fabric and the cylinder cover, improving the cleanliness of the wiping cleaning. 2. During the wiping process, the spring compression generates elastic force, causing the non-woven fabric wrapped on the wiping roller to come into close contact with the surface of the cylinder cover. When the wiping roller is pressed down, the tension of the non-woven fabric decreases, the tension spring extends and the first traction roller moves down, which can ensure the tension stability of the non-woven fabric. In addition, through the first traction roller and the second traction roller, the non-woven fabric can be tightly wrapped around the roller body of the wiping roller. Attached Figure Description

[0020] The following combination Figures 1-3 This application will be described in further detail.
[0021] Example
[0022] This application discloses an automatic cylinder head wiping mechanism. (Refer to...) Figures 1-3 It mainly includes a frame 1, on which a mounting base 2 is fixedly installed. On the mounting base 2, an unwinding mechanism 3, a wiping mechanism 4 and a winding mechanism 5 are installed. The wiping mechanism 4 is located between the unwinding mechanism 3 and the winding mechanism 5, and is mounted above the unwinding mechanism 3 and the winding mechanism 5.
[0023] The wiping mechanism 4 includes a bracket, a wiping roller 42, a first traction roller 43, and a second traction roller 44. The bracket is fixedly connected to the mounting base 2. The wiping roller 42 and the first traction roller 43 are both mounted on the bracket. The second traction roller 44 is rotatably mounted on the mounting base 2. The wiping roller 42 is located above the first traction roller 43 and the second traction roller 44. The first traction roller 43 is located on the side of the wiping roller 42 closer to the unwinding mechanism 3, and the second traction roller 44 is located on the side of the wiping roller 42 closer to the winding mechanism 5. The mounting shafts at both ends of the wiping roller 42 are connected to the bracket by an elastic connection structure 6.
[0024] The unwinding mechanism 3 and the winding mechanism 5 are used to transport the non-woven fabric through the wiping mechanism 4. When the cylinder needs to be wiped and cleaned, the robot grabs the cylinder cover and places it at the wiping mechanism 4. After the surface of the cylinder cover contacts the wiping mechanism 4, the robot continuously pushes the cylinder cover forward. Due to the action of the elastic connection structure 6, the non-woven fabric wrapped on the wiping roller 42 can contact the surface of the cylinder cover. The robot moves the cylinder cover so that the surface of the cylinder cover passes through the non-woven fabric on the wiping roller 42 at a uniform speed, achieving the technical effect of automatically wiping and cleaning the surface of the cylinder cover. When wiping is completed, the winding mechanism 5 drives the non-woven fabric to move, which can bring the clean non-woven fabric to wrap around the wiping roller 42.
[0025] Because the bracket and the wiping roller 42 are connected by an elastic connection structure 6, the elasticity of the elastic connection structure 6 can increase the contact pressure between the non-woven fabric and the cylinder cover, thereby improving the cleanliness of the wiping cleaning.
[0026] A support base 7 is fixedly installed on the mounting base 2. The bracket includes two vertical plates 41, both of which are bolted and fixed on the support base 7. The wiping roller 42 and the first traction roller 43 are installed between the two vertical plates 41.
[0027] Both vertical plates 41 are provided with first waist-shaped holes 411 for the mounting shafts at both ends of the wiping roller 42 to pass through. The elastic connection structure 6 includes two first fixing seats 61, which are respectively bolted to the outside of the two vertical plates 41. A guide rod 62 is fixedly installed on the first fixing seat 61, and a spring 63 is coaxially sleeved on the guide rod 62. The end of the mounting shaft of the wiping roller 42 that extends out of the first waist-shaped hole 411 is provided with a through hole for the guide rod 62 to pass through.
[0028] The outer walls of both vertical plates 41 are provided with second oblong holes 412 for the mounting shafts at both ends of the first traction roller 43 to pass through. The outer walls of both vertical plates 41 are fixedly mounted with second fixing seats 64. A tension spring 65 is fixedly mounted on the second fixing seat 64. The end of the tension spring 65 away from the second fixing seat 64 is connected to the end of the mounting shaft of the first traction roller 43 that extends out of the second oblong hole 412.
[0029] During the wiping process, the compression of spring 63 generates elastic force, causing the non-woven fabric wrapped on the wiping roller 42 to come into close contact with the surface of the cylinder cover. When the wiping roller 42 is pressed down, the tension of the non-woven fabric decreases, and the extension spring 65 extends the first traction roller 43 downward, ensuring the stability of the non-woven fabric tension. In addition, through the first traction roller 43 and the second traction roller 44, the non-woven fabric can be tightly wrapped around the roller body of the wiping roller 42.
[0030] Reference Figure 1The unwinding mechanism 3 includes an air shaft 31 mounted on the mounting base 2 and two limiting rollers 32. The two limiting rollers 32 are located between the air shaft 31 and the bracket. Each limiting roller 32 includes two baffles 33, and the distance between the two baffles 33 is the same as the width of the nonwoven fabric. A channel for the nonwoven fabric to pass through is formed between the two limiting rollers 32. The two limiting rollers 32 can restrict the position of the nonwoven fabric, preventing the nonwoven fabric from shifting position.
[0031] Reference Figure 1 The winding mechanism 5 includes a housing 51, a servo motor 52, and a winding roller 53. The winding roller 53 is rotatably mounted on the mounting base 2. The housing 51 is fixedly mounted on the side of the mounting base 2 away from the winding roller 53. The mounting shaft at the end of the winding roller 53 passes through the mounting base 2 and extends into the housing 51. The servo motor 52 is mounted on the outer wall of the housing 51, and the drive shaft end of the servo motor 52 is connected to the mounting shaft of the winding roller 53 extending into the housing 51 via a coupling. The servo motor 52 can drive the winding roller 53 to rotate, thereby driving the nonwoven fabric to move automatically.
[0032] Reference Figure 1 The first synchronous pulley 54 and the second synchronous pulley 55 are rotatably installed inside the housing 51. The first synchronous pulley 54 and the second synchronous pulley 55 are equipped with a synchronous belt 56. The servo motor 52 is connected to the first synchronous pulley 54 through a coupling. The second synchronous pulley 55 and the end of the take-up roller 53 that extends into the housing 51 are coaxially and fixedly connected.
[0033] By using the first synchronous pulley 54, the second synchronous pulley 55, and the synchronous belt 56 in combination, the technical effect of transmission connection between the servo motor 52 and the mounting shaft at the end of the take-up roller 53 can be achieved.
[0034] The implementation principle of an automatic cylinder cover wiping mechanism in this application embodiment is as follows: the unwinding mechanism 3 and the winding mechanism 5 are used to transport non-woven fabric through the wiping mechanism 4. When the cylinder needs to be wiped and cleaned, the robot grabs the cylinder cover and places it at the wiping mechanism 4, so that the surface of the cylinder cover makes contact and continues to push the cylinder cover. Due to the action of the elastic connection structure 6, the non-woven fabric wrapped on the wiping roller 42 can contact the surface of the cylinder cover. The robot moves the cylinder cover, so that the surface of the cylinder cover passes over the non-woven fabric on the wiping roller 42 at a uniform speed, realizing the technical effect of automatic wiping and cleaning of the cylinder cover surface. When wiping is completed, the winding mechanism 5 drives the non-woven fabric to move, which can bring the clean non-woven fabric to wrap around the wiping roller 42. Since the support and the wiping roller 42 are connected by the elastic connection structure 6, the elasticity of the elastic connection structure 6 can increase the contact pressure between the non-woven fabric and the cylinder cover, thereby improving the cleanliness of the wiping and cleaning.
[0035] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
