Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of suspension conveying, and particularly relates to an automatic mobile conveying device for rubber sealing part processing. BACKGROUND

[0002] Spraying a specific material on the surface of a rubber sealing ring base body can make the rubber sealing ring product have specific performance. For example, spraying a conductive material on the surface of a silicone rubber sealing ring base body and making the conductive material cross-link and solidify through heating to firmly adhere to the surface of the silicone rubber sealing ring base body can make the rubber sealing ring product have the function of electromagnetic shielding, and such rubber sealing ring products are widely used in aerospace, military, medical treatment and high-end communication equipment.

[0003] During the spraying operation, the rubber sealing ring base body mainly receives spraying in a suspended posture, and the suspended posture exposes the outer surface to a large area and reduces the dead angle of spraying.

[0004] However, the current suspension conveying equipment has the following problems: The first problem is the fixing of the lifting tool (which is used to suspend the rubber sealing ring base body and is in the air), and the current main fixing methods are as follows: method 1. permanent fixing (for example, the lifting tool is permanently fixed with the sliding frame through welding, and the sliding frame drives the lifting tool to move together under the action of the suspension conveying chain), which has the advantages of higher safety and the lifting tool will not fall during conveying, but is not conducive to the adaptive replacement of the lifting tool for rubber sealing ring base bodies of different sizes; method 2. active connection, the lifting tool is bent at a large angle to form an unclosed hook structure, and the hook passes through the hanging hole on the sliding frame to complete the suspension, which has the advantages of facilitating the hanging and taking of the lifting tool, and the defects are that the lifting tool will shake greatly during the suspension conveying process, causing the rubber sealing ring base body to fall off, and the rubber sealing ring base body cannot be sprayed in a stable posture; method 3. detachable fixing by simply using a threaded connection, which has the advantages of facilitating the replacement of the lifting tool and preventing the lifting tool from shaking during conveying, and the defect is that the lifting tool may accidentally fall after the threads loosen, causing a safety accident.

[0005] The second problem is the maintenance of the suspension conveying equipment. In the current equipment, the sliding frame and the lifting tool move under the drive of the suspension conveying chain and realize closed and complete track circulation. When a certain sliding frame or lifting tool on the suspension conveying chain appears a problem, the whole suspension conveying chain needs to be stopped, and the suspension conveying chain can be started again only after the problem hanging point is removed. SUMMARY

[0006] In view of the above defects existing in the prior art, the purpose of the present application is to provide an automatic mobile conveying device for rubber sealing piece processing, so as to realize safe, stable and detachable connection of the lifting appliance and avoid the influence of maintenance of a single hanging point on the overall circulation of the mobile conveying device.

[0007] To achieve the above technical purpose, the technical scheme adopted by the present application is as follows: An automatic mobile conveying device for rubber sealing piece processing, comprising a lifting appliance installed on a sliding frame, and further comprising a ball head bolt detachably installed at one end of the lifting appliance, At the end where the ball head bolt is installed, the lifting appliance is provided with a plurality of pressure fingers with deformation ability, and the plurality of pressure fingers form an enclosed space, and the ball head of the ball head bolt is located in the enclosed space and in contact with the inner surface of the pressure fingers and is subjected to the pressure generated by the deformation of the pressure fingers; Under the action of the pressure, the ball head bolt has a movement tendency of approaching the lifting appliance rather than separating from it; The sliding frame is provided with a hollow pipe portion for passing through the lifting appliance, and the diameter of the ball head is greater than the inner diameter of the hollow pipe portion.

[0008] The present application utilizes the characteristics of suspension conveying, and uses the weight of the lifting appliance, the weight of the suspended rubber sealing piece and the pressure generated by the deformation of the pressure fingers as the force for maintaining the ball head bolt from loosening, and uses the pressure fingers as physical interference for preventing the ball head bolt from coming off, so as to ensure that the ball head bolt will not loosen during the conveying process and to ensure the convenience of subsequent disassembly of the lifting appliance. Specifically, when the lifting appliance is installed on the sliding frame, the lifting appliance is first passed through the hollow pipe portion of the sliding frame, and when passing through the inner cavity of the hollow pipe portion, the pressure fingers are squeezed inwardly by the inner wall and are gathered inwardly, and after the pressure fingers pass out of the hollow pipe portion, they are restored by deformation. At this time, if the lifting appliance is in a naturally drooping state, the restored pressure fingers will be caught at the upper end of the hollow pipe portion, avoiding the falling of the lifting appliance. If the lifting appliance is to be separated from the hollow pipe portion, the pressure fingers need to be artificially pinched inwardly to gather their size range, or a greater force needs to be applied to pull down the lifting appliance, forcing the pressure fingers to be squeezed by the pipe opening of the hollow pipe portion to deform inwardly. In order to further enhance the anti-falling ability of the lifting appliance, the ball head bolt is installed on the side where the pressure fingers are arranged, and the diameter of the ball head of the ball head bolt is greater than the inner diameter of the hollow pipe portion. Therefore, as long as the part of the ball head bolt connected by threads with the lifting appliance is associated, the safety of the lifting appliance in suspension can be ensured. When installing the ball head bolt, the ball head bolt enters the surrounding space composed of the pressure fingers from outside and expands the pressure fingers outward in the process, and because the pressure fingers have the ability to deform, they have the tendency to restore deformation when they are expanded, and because of the deformation, they generate elastic force, and the tendency to restore deformation will make the inner surface of the pressure finger fit the ball head, and the elastic force generated by the deformation will fix the ball head bolt on the lifting appliance as a pressure, when the pressure finger completely enters the surrounding space formed by the pressure fingers, on the one hand, the outer pressure finger will act as a fence for interference, preventing the ball head bolt from escaping from the surrounding space, on the other hand, the pressure of the pressure finger will make the ball head bolt have a movement tendency to approach the lifting appliance rather than separate from it; In this way, even if the carriage and the lifting appliance shake during transportation, such shaking cannot cause the threaded connection between the ball head bolt and the lifting appliance to be eliminated, because when the ball head bolt wants to separate from the lifting appliance by rotating itself, on the one hand, the ball head bolt needs to rotate about its own axis, on the other hand, the ball head bolt will move away from the lifting appliance, and this movement is physically interfered by the pressure finger and blocked by the pressure of the pressure finger, so under normal transportation conditions, the ball head bolt cannot move away from the lifting appliance; In terms of utilizing the weight of the suspended transportation, when the lifting appliance suspends the rubber sealing element and naturally sags, the weight of the lifting appliance and the rubber sealing element will be transmitted to the carriage through the pressure finger, because the outer surface of the pressure finger is in contact with the pipe of the hollow pipe part, and the inner surface is in contact with the ball head, under the action of gravity, the pressure finger between the two is naturally clamped, at this time, the pressure finger is also subjected to the reaction force from the pipe of the hollow pipe part, which causes the pressure finger to further contract inward and tightly fit the surface of the ball head, exerting greater pressure on the ball head, and the further fitting of the pressure finger also helps to maintain the stability of the surrounding space and prevent the ball head from breaking through the surrounding space formed by the pressure finger; Finally, when the lifting appliance in other suspension forms needs to be disassembled and replaced, the worker moves the lifting appliance upward by a small distance, the essence of this action is to avoid the outer surface of the pressure finger being subjected to the reaction force from the pipe of the hollow pipe part, reducing the difficulty of opening the pressure finger, then the worker rotates the ball head bolt to make the ball head bolt overcome the pressure of the pressure finger and forcibly move away from the lifting appliance, in this process, the pressure finger expands and deforms outward, opening the surrounding space, and the ball head bolt can be separated from the lifting appliance, finally, the worker manually contracts the pressure finger to make the size range of the pressure finger smaller than the inner size of the hollow pipe part, at this time, pulling the lifting appliance can make the pressure finger enter the inner cavity of the hollow pipe part and finally separate from the hollow pipe part, as for the installation process, it has been described above and will not be repeated here.

[0009] Advantages of the present application: 1. Utilizing the characteristics of suspended conveying, the weight of the lifting device, the weight of the suspended rubber seal, and the pressure generated by the deformation of the pressure finger are used as the force to keep the ball head bolt from loosening. The pressure finger also serves as a physical interference to prevent the ball head bolt from coming off. This ensures that the ball head bolt will not loosen during the conveying process and also ensures the convenience of subsequent disassembly and assembly of the lifting device. 2. It can solve the problem of overall shutdown caused by maintenance of a single hanging point in a closed conveyor system. Attached Figure Description

[0011] The technical solutions of the present invention will be described in detail below with reference to specific embodiments and accompanying drawings. The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the present invention; these descriptions are explanatory and exemplary, and should not be construed as limiting the implementation methods or the scope of protection of the present invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein. Example

[0012] like Figure 4 , 5 As shown in Figures 6, 8, and 9, this embodiment provides an automated mobile conveying device for processing rubber seals, including a lifting device 10 mounted on a carriage 30, and a ball head bolt 20 detachably mounted on one end of the lifting device 10. At one end where the ball head bolt 20 is installed, the lifting device 10 is provided with a number of pressure fingers 12 that are capable of deformation. The number of pressure fingers 12 form an enclosing space. The ball head 21 of the ball head bolt 20 is in the enclosing space and is in contact with the inner surface of the pressure fingers 12, and is subjected to the pressure generated by the deformation of the pressure fingers 12. Under pressure, the ball head bolt 20 has a tendency to move toward the lifting device 10 rather than separate; The carriage 30 is provided with a hollow tube section 31 for passing through the lifting device 10, and the diameter of the ball head 21 is larger than the inner diameter of the hollow tube section 31.

[0013] In this embodiment, the characteristics of suspended conveying are utilized. The weight of the lifting device 10, the weight of the suspended rubber seal, and the pressure generated by the deformation of the pressure finger 12 are used as the force to keep the ball head bolt 20 from loosening. The pressure finger 12 is used as a physical interference to prevent the ball head bolt 20 from coming off. This ensures that the ball head bolt 20 will not come off during the conveying process and also ensures that the lifting device 10 can be easily disassembled later. Specifically, when the lifting tool 10 is installed on the sliding frame 30, first, the lifting tool 10 is passed through the hollow pipe part 31 of the sliding frame 30, and when passing through the inner cavity of the hollow pipe part 31, the pressing fingers 12 are squeezed inwardly by the inner wall and are contracted, and after the pressing fingers 12 pass out of the hollow pipe part 31, the pressing fingers 12 are restored by deformation, at this time, if the lifting tool 10 is in a naturally drooping state, the restored pressing fingers 12 will be clamped at the upper end of the hollow pipe part 31, avoiding the falling of the lifting tool 10, if the lifting tool 10 is separated from the hollow pipe part 31, the pressing fingers 12 need to be manually pinched inwardly to contract the size range, or a greater force is applied to pull down the lifting tool 10, forcing the pressing fingers 12 to be squeezed and deformed inwardly with the pipe opening of the hollow pipe part 31; In order to further enhance the anti-falling ability of the lifting tool 10, a ball head bolt 20 is installed on one side of the pressing fingers 12, and the diameter of the ball head 21 of the ball head bolt 20 is greater than the inner diameter of the hollow pipe part 31, so that as long as the part of the ball head bolt 20 threadedly connected with the lifting tool 10 is associated, the safety of the lifting tool 10 can be ensured; When the ball head bolt 20 is installed, the ball head bolt 20 enters the surrounding space formed by the pressing fingers 12 from the outside and expands the pressing fingers 12 outwardly in the process, and since the pressing fingers 12 have the ability to deform, they have a tendency to restore the deformation when being expanded, and the elastic force generated by the deformation will make the inner surface of the pressing fingers 12 fit the ball head 21, and the elastic force generated by the deformation will fix the ball head bolt 20 on the lifting tool 10 as a pressure, when the pressing fingers 12 completely enter the surrounding space formed by the pressing fingers 12, on the one hand, the pressing fingers 12 on the outside will act as a fence for interference, preventing the ball head bolt 20 from separating from the surrounding space, and on the other hand, the pressure of the pressing fingers 12 will make the ball head bolt 20 have a tendency to move towards the lifting tool 10 rather than separate from the lifting tool 10; In this way, even if the sliding frame 30 and the lifting tool 10 are shaken during transportation, the shaking cannot cause the threaded connection between the ball head bolt 20 and the lifting tool 10 to be eliminated, because when the ball head bolt 20 wants to separate from the lifting tool 10 by rotating itself, the ball head bolt 20 needs to rotate about its own axis on the one hand, and on the other hand, the ball head bolt 20 will move away from the lifting tool 10 about its own axis, and this movement is physically interfered by the pressing fingers 12 and blocked by the pressure of the pressing fingers 12, so that under normal transportation conditions, the ball head bolt 20 cannot move away from the lifting tool 10; In utilizing the weight characteristic of suspended conveying, when the rubber seal is suspended by the spreader 10 and hangs naturally, the weight of the spreader 10 and the rubber seal is transferred to the carriage 30 through the pressure finger 12. Because the outer surface of the pressure finger 12 is in contact with the edge of the hollow tube 31 and the inner surface is in contact with the ball head 21, the pressure finger 12 between the two is naturally clamped under the action of gravity. At this time, the pressure finger 12 is also subjected to the reaction force from the edge of the hollow tube 31. This reaction force causes the pressure finger 12 to further contract inward and stick to the surface of the ball head 21, applying greater pressure to the ball head 21. The further contact of the pressure finger 12 also helps to maintain the stability of the enclosed space and prevent the ball head 21 from breaking through the enclosed space formed by the pressure finger 12. Finally, when it is necessary to disassemble and replace the lifting device 10 with other types of hooks 14, the operator moves the lifting device 10 upward a short distance. The essence of this action is to avoid the outer surface of the pressure finger 12 being subjected to the reaction force of the hollow tube 31, thus reducing the difficulty of opening the pressure finger 12. Subsequently, the operator screws the ball head bolt 20, causing the ball head bolt 20 to overcome the pressure of the pressure finger 12 and forcibly move away from the lifting device 10. During this process, the pressure finger 12 expands and deforms outward, opening the enclosing space, allowing the ball head bolt 20 to separate from the lifting device 10. Finally, the operator manually tightens the pressure finger 12, making the size range of the pressure finger 12 smaller than the inner size of the hollow tube 31. At this time, pulling the lifting device 10 can allow the pressure finger 12 to enter the inner cavity of the hollow tube 31 and eventually separate from the hollow tube 31. As for the installation process, it has been described above and will not be repeated here. Example

[0014] like Figure 10 As shown, this embodiment provides an automated mobile conveying device for processing rubber seals. The difference from Embodiment 1 is that the inner surface of the pressure finger 12 is provided with a deformation layer 1 for increasing the coefficient of friction and contact area. The ball head bolt 20 is provided with a boss 22 and a screw 23. The ball head 21 is located on one side of the boss 22, and the screw 23 is located on the other side of the boss 22. The ball head 21, the boss 22 and the screw 23 have the same axis of rotation. A deformation layer 2 is provided on the side of the boss 22 near the screw 23.

[0015] In this embodiment, the difficulty of the ball head bolt 20 to rotate is increased by increasing the coefficient of friction, thereby preventing the ball head bolt 20 from loosening. The inner surface of the pressure finger 12 contacts the ball head 21. Therefore, a deformation layer 1 is provided on the inner surface of the pressure finger 12. The deformation layer 1 is not only used to increase the coefficient of friction, but also to increase the contact area with the ball head 21 and increase the binding effect on the ball head 21. After the screw 23 in the ball head bolt 20 is screwed into the threaded hole 11 of the lifting device 10, the boss 22 contacts the end face of the lifting device 10. The deformation layer 2 located on the side of the boss 22 can increase the difficulty of the ball head bolt 20 to rotate. Embodiment

[0016] As Figure 11 , 12 shown, the embodiment provides an automatic mobile conveying device for rubber sealing piece processing, which is different from embodiment 1 in that the force exertion problem when disassembling the ball head bolt 20 is further solved, and the implementation structure is that the surface of the ball head 21 is provided with a groove 24 or a wrench head 25 for screwing.

[0017] In this embodiment, the groove 24 or the wrench head 25 is arranged to facilitate the rotation of the ball head bolt 20. When arranging the groove 24 or the wrench head 25, the groove 24 or the wrench head 25 should not interfere with the pressing finger 12 when rotating. The groove 24 is mainly arranged to match various screwing tools, and the wrench head 25 is arranged for manual screwing. When disassembling the ball head bolt 20, the wrench head 25 can be used as a force point for holding and exerting force, which facilitates the staff to exert force to make the ball head 21 extrude the pressing finger 12 to expand outward, so as to facilitate the ball head 21 to enter or separate from the surrounding space. Embodiment

[0018] As Figure 13 shown, the embodiment provides an automatic mobile conveying device for rubber sealing piece processing, which is different from embodiment 1 in that the shape of the pressing finger 12 is limited. The pressing finger 12 is provided with a middle section 121, a lower section 122 and an upper section 123. The lower section 122 is connected to the lower edge of the middle section 121, and the upper section 123 is connected to the upper edge of the middle section 121. The middle section 121, the lower section 122 and the upper section 123 connected in sequence from bottom to top all contact the ball head 21.

[0019] In this embodiment, the pressing finger 12 composed of the middle section 121, the lower section 122 and the upper section 123 is used to surround different positions of the ball head 21. The middle section 121 mainly surrounds the waist position of the ball head 21, the lower section 122 mainly surrounds the middle lower position of the ball head 21, and the upper section 123 mainly surrounds the middle upper position of the ball head 21. The surrounding of the ball head 21 by the middle section 121, the lower section 122 and the upper section 123 can form effective physical interference to prevent the ball head bolt 20 from separating from the surrounding space. The three sections are all in contact with the ball head 21, so that the pressure can be effectively transmitted. Embodiment

[0020] As Figure 14 shown, the embodiment provides an automatic mobile conveying device for rubber sealing piece processing, which is different from embodiment 4 in that the contact degree of the pressing finger 12 with the ball head bolt 20 is increased, and the sealing of the ball head bolt 20 by the pressing finger 12 is strengthened. The implementation structure is that the inner corner of the upper section 123 and the middle section 121 is provided with an arc surface 124 matching the arc of the ball head 21.

[0021] In this embodiment, the transition between the upper section 123 and the middle section 121 is additionally limited to conform to the curvature of the ball head 21. This is because the ball head 21 contacts a plane at a point, and the contact area is limited, which is not conducive to the closure of the ball head bolt 20 by the pressing finger 12. In order to prevent the ball head bolt 20 from moving away from the lifting appliance 10, the arc surface 124 at the inside corner of the upper section 123 and the middle section 121 closely conforms to the ball head 21, and the conforming area is large. This structure can increase the interference to the escape movement of the ball head bolt 20. Embodiment

[0022] As shown in Figure 7 , the present embodiment provides an automatic mobile conveying device for rubber sealing piece processing. The difference from embodiment 1 is that it further solves the problem of inconvenient operation of the pressing finger 12 and the problem of possible damage to the pressing finger 12 when it is clamped. The implementation structure is that a chamfer for expanding the contact area with the pressing finger 12 is arranged at the edge of the inner cavity of the hollow pipe part 31 near one end of the ball head bolt 20. The inner cavity of the hollow pipe part 31 includes an upper cylindrical cavity 33 and a lower circular table cavity 34.

[0023] In this embodiment, the chamfer on the side of the hollow pipe part 31 close to the ball head bolt 20 is used to increase the contact area with the outer surface of the pressing finger 12 and reduce the pressure on the pressing finger 12, so as to avoid damage to the pressing finger 12. On the other hand, the chamfer here plays a role of smooth guiding for the action of the pressing finger 12 to disengage from the constriction. The hollow pipe part 31 changes from a simple circular table cavity 34 to an upper cylindrical cavity 33 and a lower circular table cavity 34. The circular table cavity 34 is mainly used to reduce the difficulty of installing the lifting appliance 10. Since the circular table cavity 34 is larger at the bottom and smaller at the top, it is easier for the pressing finger 12 to enter the circular table cavity 34. With the constriction of the upper part of the circular table cavity 34, the pressing finger 12 is inwardly constricted, so as to smoothly enter the cylindrical cavity 33. Therefore, during installation, it is not necessary to manually constrict the pressing finger 12. Embodiment

[0024] As shown in Figure 6 , 7 , the present embodiment provides an automatic mobile conveying device for rubber sealing piece processing. The difference from embodiment 1 is that it solves the problem of possible circumferential rotation of the lifting appliance 10, and limits the upward movement space of the lifting appliance 10. The implementation structure is that the circumference of the lifting appliance 10 is formed with a clamping block 13 by outward protrusion, and the pipe wall of the hollow pipe part 31 is provided with at least one clamping groove 32 for clamping into the clamping block 13.

[0025] In this embodiment, when the locking block 13 enters the locking groove 32, the locking groove 32 restricts the circumferential freedom of the lifting device 10, preventing the lifting device 10 from rotating or shaking during movement, which would cause the rubber seal to come off. The locking block 13 cooperates with the locking groove 32 at different circumferential positions, which determines the circumferential posture of the lifting device 10. In addition, depending on the actual situation, if some mobile conveying conditions are more severe, the swaying of the spreader 10 is more common. In order to avoid the rubber seals from coming off due to violent shaking in the vertical direction, the upward space of the spreader 10 can be limited by changing the design dimension of the axial position of the locking block 13 on the spreader 10. When the lifting device 10 is in a naturally hanging state, the slot 32 has an opening for the locking block 13 to be inserted downwards, while the bottom of the slot above is closed. After the locking block 13 enters the slot 32, the distance between the locking block 13 and the bottom of the slot 32 is the space for the lifting device 10 to move upwards, because when the lifting device 10 moves the locking block 13 upwards as a whole, the bottom of the slot 32 will abut against the locking block 13. Example

[0026] like Figure 7 As shown, this embodiment provides an automated mobile conveying device for processing rubber seals. The difference from embodiment 1 is that it reduces the requirements for the assembly accuracy of the lifting device 10 when slight jumping of the lifting device 10 is not allowed. The implementation structure is that an elastic body is provided at the bottom of the groove 32.

[0027] In this embodiment, when the lifting device 10 is in a naturally drooping state, its downward movement is blocked by the pressure finger 12 and the ball head bolt 20. The upward movement of the lifting device 10 depends on the distance between the locking block 13 and the bottom of the slot 32. This distance is influenced by two factors: firstly, the design dimension of the axial position of the locking block 13 on the lifting device 10; and secondly, the height of the lifting device 10 relative to the slide 30. The height of the lifting device 10 depends on the height at which the pressure finger 12 and the ball head bolt 20 will engage with the hollow tube section 3. Because there are always assembly gaps during the assembly process, the height of the lifting device 10 will change very slightly each time it is installed. This change may cause the originally designed zero distance between the locking block 13 and the bottom of the slot 32 to change, which may still cause the lifting device 10 to have slight jumping. The elastic body can compensate for the dimensional changes caused by the assembly gap through its own slight deformation. Although the elastic body can still be compressed, its compression range is extremely limited and the severity of the jumping of the lifting device 10 is reduced. In some installation examples, the lifting tool 10 is inserted into the hollow tube part 31, the pressing fingers 12 are unfolded after protruding from the hollow tube part 31, the ball head bolt 20 is installed on the lifting tool 10, the pressing fingers 12 surround the ball head bolt 20 and apply force to the ball head bolt 20, the clamping block 13 enters the inside of the clamping groove 32 and compresses the elastic body, when the lifting tool 10 is in a natural drooping state, due to the existence of the gap, the lifting tool 10 can have a slight position change in the height direction, and this change is compensated by the deformation of the elastic body between the clamping block 13 and the clamping groove 32, if the elastic body is not arranged, the gap between the clamping block 13 and the bottom of the clamping groove 32 can be caused due to the slight change in the height position of the lifting tool 10, the lifting tool 10 can have a slight jumping during the conveying process with the gap as the space for the up and down movement. Embodiment

[0028] As shown in Figure 1 , 2 , 3, the embodiment provides an automatic moving conveying device for rubber sealing piece processing, which is different from the embodiment 1 in that the problem of overall shutdown caused by single hanging point maintenance of the closed conveying is solved, and the implementation structure comprises a plurality of slide rails 40 for guiding and bearing the slide frames 30, a plurality of slide rails 40 form a non-connected outbound line 50 and a return line 60, the outbound line 50 and the return line 60 are arranged with a transfer platform at both ends. The transfer platform comprises a power source and a slide rail 70 which only has a horizontal translation movement in the vertical direction of the outbound line 50 and the return line 60, the output end of the power source is connected with the slide rail 70, and the slide rail 70 is at the same height with the slide rail 40.

[0029] In this embodiment, the outbound line 50 composed of slide rails 40 serves as the carrying route for the carriage 30 and the hanger 10 to the spraying chamber. The rubber seals on the hanger 10 undergo the spraying process in the spraying chamber. Taking a silicone rubber seal as an example, it hangs in a suspended manner on the hook 14 of the hanger 10. When passing through the spraying chamber, the spraying equipment sprays graphite-plated nickel conductive material onto its exposed outer surface. After the conductive material cures, it appears grayish-black, with a volume resistivity of 0.1 Ω·cm and a density of 2.0 g / cm³. Under a 100MHz electric field, its shielding performance reaches 95dB. After the rubber seal is sprayed, it is removed from the hanger 10, and the hanger 10 follows... The carriage 30 continues to move on the outbound line 50 and runs to the end of the outbound line 50. At this time, the second slide rail 70 is connected to the end of the outbound line 50 as an extension of the outbound line 50. According to the set processing rhythm, after the power source waits for a set time, it drives the second slide rail 70 to make a translational movement about the vertical direction of the outbound line 50 and the return line 60, so that the second slide rail 70 is connected to the beginning of the return line 60. Then, the lifting device 10 follows the carriage 30 out of the second slide rail 70 and enters the return line 60, completing the crossing between the outbound line 50 and the return line 60. In addition, the principle of crossing from the return line 60 to the outbound line 50 is the same as the above principle, and will not be repeated here. There are various options for the power source. You can choose a power source that performs linear telescopic movements, such as an electric cylinder, a locking cylinder, or a servo cylinder. The power source directly transmits the movement to the slide rail 270, making the mechanism simpler, cheaper, and eliminating the need for intermediate structures. When it is necessary to remove a problematic attachment point from the circulating conveyor, simply move the carriage 30 of the attachment point to the slide rail 70, and then, driven by the power source, stop the slide rail 70 at a certain position between the outgoing line 50 and the return line 60. The attachment point can then be removed from the end of the slide rail 70 without affecting the overall operation. The horizontal movement of slide rail 270 can be guided by the slide rail slider structure; The movement of the attachment point itself can be driven by an individual power source, for example, each attachment point carries the power to drive itself about the outbound line 50 and the return line 60.
