Description

[Technical Field]

[0001] This invention relates to the technical field of cables, and in particular to the technical field of integrated automatic pretreatment devices for cable ends. [Background Technology]

[0002] Cables are wire products used to transmit electrical energy or signals. When in use, cables typically require terminals at both ends for connection between electrical appliances. Currently, before installing terminals, cable ends often require pretreatment (mainly including grinding, cleaning, and applying conductive paste) to improve conductivity between the cable and the terminals. Specifically, the pretreatment process involves manually removing the oxide layer from the connection area between the cable conductor and the terminal using a wire brush, then manually brushing away oxide debris before applying conductive paste, as illustrated in invention patents CN104967066A (a method for installing prefabricated intermediate joints of cross-linked cables) and CN104638385B (an aluminum alloy cable branch connection assembly for streetlights). However, all of these processes are done manually by workers, resulting in high labor intensity, low processing efficiency, and poor processing quality.

[0003] Currently, there are already devices on the market specifically designed for grinding, cleaning, and applying paste to cables. Examples include a cable grinding machine disclosed in utility model patent CN203787868U, a cable conductor surface cleaning device disclosed in invention patent CN105118572A, and a high-voltage cable asphalt coating machine disclosed in utility model patent CN201676796U. However, these devices are limited in function, requiring workers to sequentially feed the cables into them and disassemble and reassemble the cables before and after each step. This cumbersome operation does not significantly improve processing efficiency. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art and to propose an integrated automatic pre-processing device for cable ends, which can integrate cable grinding, cleaning and paste application operations into one machine. The overall operation is convenient, which can greatly improve processing efficiency and product processing consistency, and can also effectively reduce the labor intensity of operators.

[0005] To achieve the above objectives, this invention proposes an integrated automatic pretreatment device for cable ends, comprising an operating table, clamps, polishing tape, applying tape, a tape holder, a drive mechanism, a jetting mechanism, and a controller. The top surface of the operating table is provided with a pair of opposing clamps. The tape holder includes a base plate, a tape frame, and an adjustment assembly. The base plate and tape frame are respectively provided with a disc cable hole and a frame cable hole. The tape frame is indirectly connected to the base plate via the adjustment assembly, allowing adjustment of the eccentricity direction and degree between the disc cable hole and the frame cable hole. The polishing tape and applying tape are respectively installed on the side of the tape frame away from the base plate, forming a tape gap directly opposite the frame cable hole. The base plate is driven by the drive mechanism to rotate while moving horizontally between the two sets of clamps. Gas is injected between the disc cable hole, the frame cable hole, and the tape gap by the jetting mechanism. The controller is electrically connected to both the drive mechanism and the jetting mechanism.

[0006] Preferably, the clamp includes a clamp base and a clamp cover. The clamp base is fixed on the operating table, and the clamp cover is detachably connected to the clamp base by fasteners. The adjacent surfaces of the clamp base and the clamp cover are respectively provided with a seat arc surface and a cover arc surface.

[0007] Preferably, the adjustment assembly includes sliding columns and an adjustment handle. Several sliding columns are horizontally fixed on the base plate and located on the upper and lower sides of the cable hole of the plate. The belt frame is slidably connected to each sliding column. The adjustment handle includes a positioning block and an adjustment bolt. The positioning block is fixed on the base plate. The end of the screw of the adjustment bolt is rotatably connected to the belt frame after being screwed through the screw hole of the positioning block.

[0008] Preferably, the belt seat further includes a mandrel, which includes a shaft body and a bushing. Several shaft bodies of the mandrel are respectively horizontally arranged and one end is fixed to the belt frame. Each shaft body is rotatably connected to a bushing. The grinding tape and the application tape are respectively sleeved on part of the bushing.

[0009] Preferably, the sections of the polishing tape and the coating tape facing the gap in the tape body are straight due to the support of the mandrel.

[0010] Preferably, the belt frame is provided with several vertically arranged through slots, and one end of each shaft passes through the through slot and is fixed by fasteners.

[0011] Preferably, the drive mechanism includes a motor, a rotating platform, a frame, a transmission toothed belt, a lead screw, a lead rod, and a guide rod. The lead screw and guide rod are horizontally arranged above the operating table. The lead screw is threaded onto the lead screw. The frame is slidably connected to both the lead screw and the guide rod. The rotating platform is rotatably connected to the frame and is driven to rotate by the motor. The rotating platform and the lead screw are respectively provided with platform teeth and lead screw teeth. The transmission toothed belt is sleeved on both the rotating platform and the lead screw and meshes with the platform teeth and lead screw teeth respectively. The lead screw is also provided with an annular groove that clamps the edge of the base plate.

[0012] Preferably, the jetting mechanism includes an air pump, an air pipe, a valve seat, and a valve core. The air pump is fixed on the operating table, the valve seat is slidably connected to the guide rod, one end of the air pipe is installed at the air outlet of the air pump, and the other end is installed at the air inlet of the valve seat. The valve core is rotatably connected to the valve seat, with one end fixed to the base plate and the other end rotatably connected to the frame. The valve core has a valve body cable hole facing the disc cable hole, and the wall of the valve body cable hole is surrounded by several air holes that penetrate the outer wall of the valve core.

[0013] The beneficial effects of this invention are:

[0014] 1) By setting a pair of clamps on the top surface of the operating table to hold and fix the cable, the grinding tape and the coating tape are switched with the seat and then applied to the cable in sequence. At the same time, the driving mechanism drives the grinding tape and the coating tape to rotate around the cable and move horizontally. In addition, the jetting mechanism continuously sprays compressed gas, thus realizing the grinding, cleaning and coating of the cable in one machine. The overall operation is convenient, which can greatly improve the processing efficiency and the processing consistency of the product, and can also effectively reduce the labor intensity of the operator.

[0015] 2) The clamp is formed by using a clamp base and a clamp cover with an arc surface on the adjacent side respectively. The clamp base and the clamp cover are connected in a detachable manner with fasteners, which not only ensures the clamping stability of the cable, but also facilitates the quick installation and removal of the cable.

[0016] 3) By using a sliding column and an adjusting handle to form an adjustment component, and adding a shaft and bushing to form a mandrel, the grinding tape and the coating tape can rotate synchronously during operation by utilizing the friction between them and the cable. This avoids the grinding tape and the coating tape always grinding or coating the cable at the same point, thus effectively extending the service life of the grinding tape and the coating tape.

[0017] 4) By using a motor, rotating platform, frame, transmission toothed belt, screw nut, screw rod and guide rod to form a drive mechanism, the overall structure is not only simple and compact, but also enables the grinding tape and coating tape to rotate around the cable while traveling in a straight line along the screw rod, ensuring the fullness and uniformity of grinding and coating operations.

[0018] 5) By using an air pump, air pipe, valve seat and valve core to form an air jet mechanism, it does not affect the specific activities of sanding and applying tape, and can also spray compressed gas synchronously near the sanding position to quickly blow away the sanding debris.

[0019] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0027] See Figures 1 to 6The present invention relates to an integrated automatic pretreatment device for cable ends, comprising an operating table 1, clamps 2, a polishing tape 3, an applicator tape 4, a tape holder 5, a drive mechanism 6, an air jet mechanism 7, and a controller. The top surface of the operating table 1 is provided with a pair of oppositely arranged clamps 2. The tape holder 5 includes a base plate 51, a tape frame 53, and an adjustment component. The base plate 51 and the tape frame 53 are respectively provided with a disc cable hole and a frame cable hole. The tape frame 53 is indirectly connected to the base plate 51 through the adjustment component, thereby adjusting the eccentricity direction and degree between the disc cable hole and the frame cable hole. The polishing tape 3 and the applicator tape 4 are respectively installed on the side of the tape frame 53 away from the base plate 51, forming a tape gap facing the frame cable hole. The base plate 51 is driven by the drive mechanism 6 to rotate while moving horizontally between the two sets of clamps 2. Gas is injected between the disc cable hole, the frame cable hole, and the tape gap by the air jet mechanism 7. The controller is electrically connected to the drive mechanism 6 and the air jet mechanism 7. Among them, for the adhesive tape 4, the conductive paste on its surface can be manually replenished by workers periodically, or it can be electrically replenished by using a funnel or other dispensing device with a solenoid valve.

[0028] The clamp 2 includes a clamp base 21 and a clamp cover 22. The clamp base 21 is fixed on the operating table 1, and the clamp cover 22 is detachably connected to the clamp base 21 by fasteners.

[0030] The belt holder 5 also includes a spindle 54, which includes a shaft body and a bushing. Several shaft bodies of the spindle 54 are horizontally arranged and one end is fixed to the belt frame 53. Each shaft body is rotatably connected to a bushing. The polishing tape 3 and the coating tape 4 are respectively sleeved on part of the bushing.

[0031] The sections of the polishing tape 3 and the coating tape 4 facing the gap in the tape body are straight due to the support of the spindle 54.

[0032] The belt frame 53 has several vertically arranged through slots, and one end of each shaft passes through the through slot and is fixed by fasteners. The addition of through slots allows the position of each shaft to be adjusted up and down as needed, thereby ensuring that the grinding tape 3 and the application tape 4 remain taut during operation.

[0033] The drive mechanism 6 includes a motor 61, a rotating platform 62, a frame 63, a transmission toothed belt 64, a lead screw 65, a lead screw 66, and a guide rod 67. The lead screw 66 and guide rod 67 are horizontally arranged above the operating table 1. The lead screw 65 is threaded onto the lead screw 66. The frame 63 is slidably connected to both the lead screw 66 and guide rod 67. The rotating platform 62 is rotatably connected to the frame 63 and is driven to rotate by the motor 61. The rotating platform 62 and the lead screw 65 are respectively provided with platform teeth 621 and female teeth 651. The transmission toothed belt 64 is sleeved on both the rotating platform 62 and the lead screw 65 and meshes with the platform teeth 621 and female teeth 651 respectively. The lead screw 65 is also provided with an annular clamping groove 652 to clamp the edge of the base plate 51. In addition, a limit switch can be provided on the top surface of the operating table 1 to limit the range of movement of the base plate 51 along the lead screw 66.

[0034] The jetting mechanism 7 includes an air pump 71, an air pipe 72, a valve seat 73, and a valve core 74. The air pump 71 is fixed on the operating table 1. The valve seat 73 is slidably connected to the guide rod 67. One end of the air pipe 72 is installed at the air outlet of the air pump 71, and the other end is installed at the air inlet of the valve seat 73. The valve core 74 is rotatably connected to the valve seat 73, with one end fixed to the base plate 51 and the other end rotatably connected to the frame 63. The valve core 74 is provided with a valve body cable hole facing the disc cable hole. The wall of the valve body cable hole is surrounded by several air holes that penetrate the outer wall of the valve core 74.

[0035] Working process of this invention:

[0036] Before operation, the cable 8 is passed through the gap in the belt body, the cable hole in the frame, the cable hole in the disc body, and the cable hole in the valve body in sequence, and then clamped and fixed using two sets of clamps 2. Specifically, the clamping and fixing operation of the clamps 2 involves first passing the cable 8 between the arc surface of the base body and the arc surface of the cover body, and then using fasteners to fix the clamp base 21 and the clamp cover 22 together to clamp the cable 8.

[0037] Before the polishing operation, first tighten the adjusting bolt 552 to move the belt bracket 53 along each sliding column 52 until the cable is in close contact with the polishing tape 3. Next, start the motor 61 to drive the rotating platform 62 to rotate forward or backward repeatedly, while the transmission toothed belt 64 drives the screw nut 65 to rotate forward or backward repeatedly and move back and forth along the screw 66. At this time, the base plate 51 and the polishing tape 3 and the coating tape 4 connected to it can rotate forward or backward and move back and forth along the screw 66 under the drive of the screw nut 65, thereby polishing the cable 8 through the polishing tape 3. In addition, during this polishing process, the air pump 71 can be started to allow compressed gas to enter the valve core 74 through the air pipe 72 and the valve seat 73 to quickly clean up the debris from the polishing. Specifically, the compressed gas sprayed from the air outlet of the valve seat 73 can enter the cable hole of the valve body through each air hole, and then blow out the debris from the polishing along the cable 8.

[0038] Before applying the conductive paste, first tighten the adjusting bolt 552 to move the tape holder 53 along each slide post 52 until the cable is in close contact with the application tape 4. Then, manually apply conductive paste to the surface of the application tape 4. Next, start the motor 61 so that the application tape 4 rotates around the cable 8 and moves horizontally, gradually transferring the conductive paste to the surface of the cable 8.

[0039] After completing the grinding, cleaning, and paste application, simply loosen the two sets of clamps 2 and then remove the cable 8.

[0040] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
