Description

Technical Field

[0001] The present invention relates to the technical field of copper ring processing, and specifically relates to an automatic equipment and process for surface treatment of copper rings. Background Art

[0002] As a key component widely used in the fields of electronics, electric power, mechanical manufacturing, etc., the surface treatment process of copper rings (such as electroplating, polishing, passivation, anti-oxidation coating, etc.) plays a decisive role in the conductivity, corrosion resistance and appearance quality of the product.

[0003] The traditional surface treatment process of copper rings mainly relies on manual or semi-automatic equipment to complete, and there are the following technical pain points:

[0004] 1) Poor process consistency: Manual operation is easily affected by factors such as experience level and fatigue degree, resulting in large fluctuations in parameters such as surface treatment thickness and uniformity. Especially for micro copper rings with high-precision requirements, the finished product rate is less than 60%.

[0005] 2) Low production efficiency: The traditional production line needs to frequently adjust the tooling fixtures to adapt to different specifications of copper rings, and the line change time accounts for up to 30%, which is difficult to meet the flexible production requirements of multi-variety and small-batch orders.

[0006] Therefore, there is a need for an automatic equipment for surface treatment of copper rings to solve the above problems, so as to optimize the surface treatment of copper rings and improve the production efficiency of copper rings. Summary of the Invention

[0007] To solve the above technical problems, the present invention provides an automatic equipment and process for surface treatment of copper rings.

[0008] The technical solution of the present invention is: An automatic equipment for surface treatment of copper rings, including a base, a machine cover, and a cleaning unit, a wind cutting unit, a first polishing unit, a flipping unit and a second polishing unit sequentially arranged on the base;

[0009] A truss assembly for transferring copper rings is provided on the base, and the truss assembly is composed of a truss support arranged on the base, a horizontal rail moving horizontally along the truss support, a lifting rod arranged on the horizontal rail, and a clamping member arranged on the lifting rod;

[0010] The clamping member includes a hollow carrier plate and a clamping assembly arranged on the bottom surface of the carrier plate. The clamping assembly is composed of a plurality of clamping rods. The clamping rods extend into the interior of the carrier plate and are slidably connected to the carrier plate. The top of the clamping rod is connected to the carrier plate through a spring rod;

[0011] The inside of the clamping rod is hollow, and a friction block that can extend is provided on the side wall of the clamping rod. A push block for triggering the extension of the friction block is slidably arranged up and down inside the clamping rod. A linkage rod for connecting to an adjacent clamping rod is provided at the top of the clamping rod, and both ends of the linkage rod are respectively connected to the push blocks inside the corresponding clamping rods. A suction cup for sucking and engaging with the end face of the copper ring is provided at the bottom end of the clamping rod. The suction cup is connected to a negative pressure control chamber provided inside the carrier plate through a pipeline for controlling the suction and release of the suction cup.

[0012] Description: By using the optimized truss assembly for automatic processing of the copper ring surface, the problems of poor process consistency and low production efficiency can be effectively avoided. Since the copper ring needs to be switched and moved between multiple units and clamped multiple times, for a copper ring with a relatively narrow ring surface, problems such as deformation are likely to occur. Therefore, we have optimized the clamping parts of the truss assembly. By using the relative displacement difference between the clamping rods, the clamping rods can surround and fix the copper ring, so that through the setting of the above clamping parts, the above problems can be effectively avoided, preventing the copper ring from deforming during multiple clamping and moving, and the clamping is stable and the response speed is fast.

[0013] Furthermore, a first bladder is provided at the top inside the clamping rod, and a clamping plate that can extend to clamp the copper ring is provided at the bottom inside the clamping rod. The clamping plate is connected to the bottom inside the clamping rod through a second bladder. The first bladder and the second bladder are communicated through a pipeline, and both the first bladder and the second bladder are air bladders or liquid bladders.

[0014] Description: Through the setting of the first bladder, the second bladder and the clamping plate, on the basis of the friction block of the clamping rod, a supporting force can be provided for the copper ring at the bottom end of the clamping rod, thereby further preventing the copper ring from falling off the clamping part, improving the stability of the clamping of the copper ring by the clamping part, and this function can be achieved without an electric component.

[0015] Furthermore, the base is composed of a longitudinal part and a transverse part, and there are two sets of truss assemblies. One set of truss assemblies is arranged on the transverse part, and the other set of truss assemblies is arranged on the longitudinal part.

[0016] Description: By setting the transverse and longitudinal parts, the lateral occupied space of the base can be effectively reduced. By using the cooperation of the two sets of truss assemblies, the problems of transfer and switching of the longitudinal and transverse parts can be solved, so that the copper ring can be automatically processed on the surface under each unit process.

[0017] Even further, the cleaning unit and the air knife unit are arranged on the longitudinal part, the first polishing unit, the flipping unit and the second polishing unit are arranged on the transverse part, and a translation transition unit is provided on the base between the air knife unit and the first polishing unit. The translation transition unit includes a panel and moving V-shaped blocks located on both sides of the panel and used for clamping the copper ring. The moving V-shaped blocks are chain-drivenly connected to the panel through a transmission chain.

[0018] Description: By means of the translation transition unit, the problems of longitudinal and lateral partial transfer and switching can be further eliminated, and the two truss components can be fully coordinated to solve the problem of copper ring transfer at the joint of the two truss components.

[0019] Furthermore, a feeding station and a discharging station are sequentially arranged at the front end and the rear end of the base, and both the feeding station and the discharging station are conveyor belt structures formed by parallel arrangement of a plurality of electric rollers. The feeding station is also provided with a fixed V-shaped block for positioning the copper ring.

[0020] Description: Through the feeding station and the discharging station, the automatic processing of the copper ring surface can be further improved. Workers only need to place the copper ring at the feeding station and wait for the processed copper ring at the discharging station. In this way, the machine cover can fully cover each unit, thereby improving the safety of equipment operation.

[0021] Furthermore, the cleaning unit includes a cleaning chamber, a cleaning basket arranged vertically and movably in the cleaning chamber, and a lifting motor for driving the up-and-down movement of the cleaning basket. An ultrasonic generator is arranged in the cleaning basket.

[0022] Description: Since copper is prone to form copper oxide or corrosion spots on its surface, the cleaning unit can fully clean the copper ring, effectively remove oxides and corrosion products, restore the original color of copper metal, and avoid the influence of oil stains on the copper ring on subsequent processing.

[0023] Furthermore, the air-knife unit includes an air-knife chamber, a lifting and rotating mechanism rotatably arranged at the bottom inside the air-knife chamber, and high-pressure air knives arranged on the inner wall of the air-knife chamber; a locking block for fixing the copper ring is provided on the lifting and rotating mechanism.

[0024] Description: Through the air-knife unit, rapid drying can be achieved by means of high-speed airflow, thereby greatly shortening the drying time of the copper ring. Compared with traditional electric heating drying, the energy consumption can be reduced by more than 30%. And the design of the wind tunnel effect can ensure that the airflow evenly covers the surface of the object, thereby avoiding local residual water stains. At the same time, the wind speed and temperature can be accurately adjusted to meet the drying requirements of temperature-sensitive materials such as copper wires.

[0025] Furthermore, both the first polishing unit and the second polishing unit include a chuck assembly for fixing the copper ring, a high-pressure air knife arranged on one side of the chuck assembly, a polishing assembly arranged on the other side of the chuck assembly, and a dust suction port arranged on the chuck assembly; a locking block for fixing the copper ring is provided on the chuck assembly; the polishing assembly is composed of a rotating motor and a friction wheel arranged at the output end of the rotating motor. The first polishing unit has a friction wheel for polishing one end face and the outer circle of the copper ring, and the second polishing unit has a friction wheel for polishing the other end face and the inner hole of the copper ring.

[0026] Description: Through the cooperation of the first polishing unit and the second polishing unit, the two sides of the copper ring can be ground and polished efficiently and quickly, improving the surface treatment efficiency of the copper ring. And with the design of the high-pressure air knife and the dust suction port, the dust problem during the grinding of the copper ring can be reduced, and the working environment for the surface treatment of the copper ring can be improved.

[0027] Furthermore, the flipping unit includes a flipping bracket and two jaw support frames slidably arranged on one side of the flipping bracket for clamping the copper ring. On the other side of the flipping bracket, there is a left-right rotation motor for flipping the flipping bracket by 180°, and the left-right rotation motor is connected to the base.

[0028] Description: Through the flipping unit, the copper ring can be quickly turned over to meet the requirement of switching between the front and back sides of the copper ring between the first polishing unit and the second polishing unit.

[0029] The present invention also provides an automated process for copper ring surface treatment. Based on the above-mentioned automated equipment for copper ring surface treatment, it includes the following steps:

[0030] S1. Place the copper ring to be processed at the base on one side of the cleaning unit, and use the truss assembly to clamp the copper ring and transfer it to the cleaning unit, and use the cleaning unit to perform ultrasonic cleaning on the copper ring.

[0031] S2. Use the truss assembly to clamp and transfer the copper ring to the air knife unit, and use the air knife unit to dry the copper ring.

[0032] S3. Use the truss assembly to clamp and transfer the copper ring to the first polishing unit, and use the first polishing unit to grind and polish one end face and the outer circular surface of the copper ring to remove the oxidation and slight scratches on the surface of the copper ring.

[0033] S4. Use the truss assembly to clamp and transfer the copper ring to the flipping unit, and use the flipping unit to turn the copper ring by 180°.

[0034] S5. Use the truss assembly to clamp and transfer the copper ring to the second polishing unit, and use the second polishing unit to grind and polish the other end face and the inner circular surface of the copper ring to remove the oxidation and slight scratches on the surface of the copper ring.

[0035] S6. Use the truss assembly to clamp and place it at the base on one side of the second polishing unit to obtain the processed copper ring.

[0036] Description: By using the automated equipment for copper ring surface treatment to perform automated surface treatment on the copper ring, the problem of poor process consistency in manual treatment can be effectively avoided. The parameters such as the surface treatment thickness and uniformity are highly consistent, and the production efficiency is high, which can improve the efficiency of copper ring surface treatment.

[0037] The beneficial effects of the present invention are as follows:

[0038] (1) The automated equipment for surface treatment of copper rings in the present invention can effectively solve the problems of poor process consistency and low production efficiency in the current surface treatment of copper rings. By using an optimized truss component, it can solve problems such as deformation prone to occur during multi-process transfer and clamping of copper rings with a narrow ring surface, and has stable clamping and fast response speed.

[0076] 15. The motor must meet the 2-level energy consumption standard. At the same time, the motors in the oil and dust-related stations are explosion-proof motors, meeting the requirements of relevant national standards.

[0077] 16. The cleaning, air knife, and polishing process times are manually digitally displayed and adjustable from 0 to 30 minutes.

[0078] 17. The chuck jaws are connected by pins for easy replacement, and the jaws are coated with rubber to prevent parts from being damaged by collision.

[0079] 18. According to the part specifications and surface treatment requirements, the equipment must have a convenient automatic vs. manual switching function, and at the same time be able to realize the function of skipping processes (that is, only using the cleaning or polishing function of the equipment).

[0080] 19. The touch screen and small industrial programmable process controller (hereinafter referred to as PLC) are used for unified control.

[0090] 3. The working principle of the clamping member 9 is as follows: when the clamping member 9 falls onto the copper ring to be clamped, two sets of forces provide clamping for the copper ring, as follows:

[0091] 1. The force provided by the negative pressure control chamber 90 and the suction cup to the end surface of the copper ring

[0092] The negative pressure control chamber 90 is made to have negative pressure through an air pump to increase the suction force of the suction cup. After the suction cup contacts the end face of the copper ring, the suction force of the suction cup provides the control force for the active suction and release of the lifting of the copper ring.

[0093] II. Force provided by the clamping rod 92 to the side of the copper ring

[0094] Under the upward pushing action of the copper ring, the clamping rod 92 in contact with its end face moves into the carrier 91, so that the clamping rod 92 above the copper ring and the other clamping rods 92 form a height difference. That is, for the clamping rod 92 close to the side of the copper ring, under the action of the linkage rod 96, the push block 95 moves upward, causing the friction block 94 to move outward from the clamping rod 92 and fit with the side of the copper ring to increase the friction force and provide a clamping force for the copper ring.

[0095] Under the action of the above two forces, the copper ring can be quickly and stably clamped and lifted by the clamping member 9, and the problem of deformation of the thin-walled copper ring caused by clamping the copper ring with jaw-type clamps can be avoided.

[0096] Embodiment 2: This embodiment provides an automated process for copper ring surface treatment. Based on the automated equipment for copper ring surface treatment in Embodiment 1, it includes the following steps:

[0097] S1. Place the copper ring to be processed on the loading station 11 on one side of the cleaning unit 3, and clamp the copper ring to the cleaning unit 3 through the truss assembly 8, and use the cleaning unit 3 to perform ultrasonic cleaning on the copper ring.

[0098] S2. Clamp and transfer the copper ring to the air knife unit 4 through the truss assembly 8, and use the air knife unit 4 to dry the copper ring.

[0099] S3. Clamp and transfer the copper ring to the first polishing unit 5 through the truss assembly 8, and use the first polishing unit 5 to polish the end face and outer cylindrical surface on one side of the copper ring to remove oxidation and minor scratches on the surface of the copper ring.

[0100] S4. Clamp and transfer the copper ring to the flipping unit 6 through the truss assembly 8, and flip the copper ring by 180° through the flipping unit 6.

[0101] S5. Clamp and transfer the copper ring to the second polishing unit 7 through the truss assembly 8, and use the second polishing unit 7 to polish the end face and inner cylindrical surface on the other side of the copper ring to remove oxidation and minor scratches on the surface of the copper ring.

[0102] S6. Clamp and place it on the unloading station 12 on one side of the second polishing unit 7 through the truss assembly 8 to obtain the processed copper ring.

[0103] For example: The specifications of the copper ring are: inner and outer diameters 200 - 700 mm; thickness ≤ 60 mm.

[0104] Embodiment 3: The difference between this embodiment and Embodiment 1 is that, as Figures 5-8 shown, a first bladder 97 is provided at the inner top of the chuck rod 92, and the first bladder 97 is annular to allow the pipeline at the center to pass through. Six clamping plates 98 that can extend out to clamp the copper ring are circumferentially arranged at equal intervals of 60° at the inner bottom of the chuck rod 92. The clamping plates 98 are connected to the inner bottom of the chuck rod 92 through a second bladder 99. The clamping plates 98 are L-shaped, and one end of each clamping plate is used to extend out through the opening on the side wall of the chuck rod 92. The first bladder 97 and the second bladder 99 are connected through a pipeline buried in the inner wall of the chuck rod 92. Both the first bladder 97 and the second bladder 99 are liquid bladders, and the liquid filled in the liquid bladders can be oil. It should be noted that in order to improve the efficiency of the clamping plate 98 inserting into the bottom of the copper ring, a slope design can be made on the end face of the clamping plate 98 on the side where it inserts into the copper ring.

[0105] The working principle of the above-mentioned chuck rod 92 is as follows: On the basis of Embodiment 1, further support force is provided for the copper ring. Specifically, when the chuck rod 92 is triggered from the Figure 9 initial state shown to the Figure 10 triggered state shown, the push block 95 is lifted upward by the linkage rod 96 and squeezes the second bladder 99. Thus, the contraction of the second bladder 99 causes the first bladder 97 to expand, so that each clamping plate 98 extends outwards from the chuck rod 92, thereby forming support for the end face of the copper ring. It can be understood that the clamping member 9 with different lengths of chuck rods 92 can be used according to the specific specifications of the production line.

[0106] Embodiment 4: The difference between this embodiment and Embodiment 1 is that the suction cup adopts a structure with an opening opened by pressure trigger and pipeline connection. For example, after the suction cup is squeezed and deformed, the cross rubber opening connecting the suction cup and the pipeline will open. Through such a design, the use of non-working suction cups can be avoided, and the energy consumption of the negative pressure control chamber 90 can be reduced.
