Description

Technical Field

[0001] The present invention relates to the technical field of electroplating conveying, and in particular to a copper trough suspended sensing conveying device for electroplating processing. Background Art

[0002] Electroplating is a surface treatment process that uses the principle of electrolysis to deposit a layer of metal or alloy on the surface of a conductive object. Its core purpose is to give the substrate specific properties or appearance rather than changing its overall material.

[0003] In the field of electroplating processing, technical improvements in conveying devices are crucial to improving electroplating efficiency and product quality. Traditional electroplating conveying devices, such as the suspended workpiece conveying device for electroplating processing with patent number CN214494781U, although improved in anti-deflection capability through designs such as anti-deflection plates, still have deficiencies in electroplating uniformity, compatibility, automation, and intelligence. These devices are often difficult to adapt to the electroplating needs of workpieces of different shapes or sizes, and lack intelligent sensing and automatic adjustment functions, resulting in certain limitations in electroplating efficiency and product quality.

[0004] To this end, we propose a copper trough suspended sensing conveying device for electroplating processing. Summary of the Invention

[0005] The purpose of the present invention is to provide a copper trough suspension sensing conveyor device for electroplating processing. Based on the existing technology, this device effectively solves the shortcomings of traditional electroplating conveyor devices through dynamic suspension adjustment, intelligent sensing and process optimization, efficient and precise control and other technical means;

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a copper tank suspension sensing conveying device for electroplating processing, comprising an electroplating tank group and a conveying frame, wherein the conveying frame is fixed to the top of the electroplating tank group by bolts, characterized in that a drive chain is installed in the conveying frame, and sensing conveying mechanisms are evenly installed on the drive chain;

[0007] The sensing conveying mechanism includes a conveying shell, a first rotary disk, a second rotary disk and a load sensing component. The conveying shell is evenly fixed on the drive chain. The two sides of the conveying shell are symmetrically connected to the second rotary disk. The top of the second rotary disk is symmetrically installed with a telescopic column. The conveying shell is symmetrically connected to the first rotary disk through a bearing. The central axis of the second rotary disk passes through the conveying shell and is fixed to the first rotary disk. The sensing conveying mechanism is installed on one side of the conveying shell.

[0008] A sliding control telescopic mechanism is fixedly installed in the conveying shell, and the sliding control telescopic mechanism includes an interpenetrating shell, a suspension rod and a hanger. The interpenetrating shell is fixedly connected to the inner wall of the conveying shell, and the suspension rod is slidably connected in the interpenetrating shell. One side of the suspension rod passes through the interpenetrating shell and is installed with a hanger, and a basket is installed on the hanger.

[0009] Furthermore, a tension control assembly is installed between the conveying frames, a gear is installed on the tension control assembly and is meshed with the drive chain, and the gear is placed in a position and driven by a screw rod. A guide gear is also installed between the conveying frames for driving the chain support.

[0010] Furthermore, a discharge assembly 1 is installed on one side of the top of the electroplating tank group, and a discharge assembly 2 is installed on one side of the electroplating tank group. A telescopic platform is set on the discharge assembly 1 and the discharge assembly 2 for automatically obtaining the basket on the hanger.

[0011] Furthermore, a weighing sensor, an inclination sensor and a main controller are installed in the load sensing component on the sensing conveying mechanism. The weighing sensor is used to detect the weight of the basket on the hanger, and the inclination sensor is used to monitor whether abnormal tilt occurs during the transportation of the basket on the hanger. The monitoring data is synchronously sent to the load sensing component. The main controller is used to receive data from the sensing system, control the start and stop, speed and direction of the drive chain conveying, and trigger an alarm based on the sensed abnormal data.

[0012] Furthermore, the sliding control telescopic mechanism also includes a pressure rod, a ratchet sleeve and a limit block. The pressure rod is symmetrically and slidingly connected in the interpenetrating shell, and the pressure rod is located at the bottom of the interpenetrating shell and is installed with a spring. The other end of the pressure rod passes through the interpenetrating shell and abuts against the rotary disk. The inner wall of the interpenetrating shell is movably connected with a ratchet sleeve, which consists of a ratchet and a gear, and the ratchet sleeve side gear is meshed with the inner tooth pattern of the suspension rod. The side wall of the pressure rod is rotatably connected with a pawl, and a limit block is installed on the inner wall of the interpenetrating shell and at the bottom of the ratchet group. The bottom of the limit block is provided with a spring and abuts against the bottom of the ratchet group.

[0013] Furthermore, an abutment box is fixedly connected to the inner wall of the conveying frame, a flow channel is provided at the bottom of the abutment box, a positioning plate is evenly and movably connected to the abutment box and is located in the flow channel, and a transverse groove is provided on the positioning plate and is connected to the flow channel, and the telescopic column at the top of the second turntable is located in the flow channel and is slidably connected to the flow channel.

[0014] Furthermore, an independent transmission component is evenly and movably connected to the inner wall of the abutment box and located on the notch of the corresponding electroplating tank group. The output end of the motor installed in the independent transmission component is fixedly connected to a gear, and the gear installed at the end of the positioning plate is meshed with the gear on the independent transmission component.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, dynamic suspension adjustment is adopted to improve the uniformity and compatibility of electroplating. Through the linkage design of the first and second turntables, combined with the ratchet sleeve, pressure rod and suspension rod in the sliding telescopic mechanism, the independent lifting of the hanger is realized. The double-sided hook form of the upper basket is respectively suspended on the hangers on both sides, and the height of one side is independently adjusted. The immersion posture of the basket is flexibly controlled to adapt to the electroplating requirements of workpieces of different shapes or sizes, which significantly improves the versatility of the production line. This structure allows the basket to be immersed in the electroplating tank at an inclined angle, ensuring that the surface of the special-shaped workpiece is fully exposed to the electroplating solution, solving the electroplating dead angle problem caused by traditional parallel lifting.

[0017] 2. In the present invention, intelligent sensing and process optimization are used to achieve efficient and precise control. The load sensing component integrates a weighing sensor, an inclination sensor and a main controller to monitor the weight distribution and transportation posture of the basket in real time. Once overweight, unbalanced load or abnormal tilt is detected, an alarm is immediately triggered and the start and stop or speed of the drive chain is adjusted to prevent the workpiece from falling off or uneven electroplating. At the same time, the positioning disk is driven by an independent transmission component to accurately control the rotation angle of the turntable 2 so that the basket can stay in the electroplating tank group as needed. Combined with the differentiated slot area design, the production line rhythm is optimized to avoid efficiency loss caused by waiting for the process. Finally, the telescopic table of the discharge component is linked with the hanger to realize automatic hanging of the basket, replacing the high-cost robotic arm solution and reducing equipment investment.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-7 , the present invention provides a technical solution:

[0028] Example 1: Figure 1 As shown, the copper trough hanging sensing conveying device for electroplating processing combines the professional equipment requirements of mechanical conveying, automatic control and sensing monitoring. Its core goal is to complete the movement of the basket 13 on the electroplating production line safely, efficiently and controllably, and to sense key states in real time. At the same time, the sliding control telescopic mechanism 7 can be flexibly adjusted on the sensing conveying mechanism 6, and the modular maintenance is convenient, which can realize the efficient and smooth movement and loading of the basket 13 between the electroplating lines. The sensing conveying mechanisms 6 on the adjacent sides can cooperate to cope with the baskets 13 of different shapes and sizes. The overall combination has high flexibility in adjustment, which improves the overall electroplating effect of the workpiece.

[0029] For the conveying of the basket 13, a discharge assembly 1 2 and a discharge assembly 2 3 are installed on both sides of the electroplating tank group 1. Since the bottom hanger 707 of the sliding control telescopic mechanism 7 adopts a hook, when the discharge assembly 1 2 and the discharge assembly 2 3 receive the basket 13 loaded with materials, they move synchronously with the hanger 707 at the bottom of the conveying shell 601. In the gap between the hangers 707, the basket 13 is automatically hung on the hanger 707 by telescopic height adjustment. Compared with the use of a robotic arm for loading and unloading, the material electroplating cost is reduced;

[0030] The driving chain 5 is used to complete the movement of multiple sets of sensing conveying mechanisms 6, such as Figure 2 As shown, a tension control component 12 is installed on the conveyor frame 4 inside the drive chain 5, and an auxiliary gear is provided for support, thereby constructing the entire cyclically movable conveyor line;

[0031] A contact box 8 is also installed and fixed between the conveyor frame 4 and throughout the entire drive chain 5. Figure 3 As shown, an independent transmission component 11 is provided in the contact box 8, which is correspondingly arranged according to the slots of different processes in the electroplating tank group 1, such as slots for pickling, copper plating and water washing. Different reagents are stored in each slot. As the drive chain 5 rotates, the turntable 2 603 installed on both sides of the top of the conveying shell 601 contacts the flow channel 9 at the bottom of the contact box 8, specifically the telescopic column 604 on the top of the turntable 2 603 contacts the flow channel 9, as shown in FIG. Figure 5 As shown, the telescopic column 604 itself is retractable and movable to cope with the dynamic contact with the bottom of the abutment box 8 during the rotation of the drive chain 5, and to prevent the installation of the telescopic column 604 from hindering the overall movement of the load sensing component 605;

[0032] like Figure 3 As shown, the second rotary disc 603 in the flow channel 9 needs to be movable, and the flow channel 9 is provided with a positioning disc 10 at the center side of the corresponding notch, as shown in FIG. Figure 7 As shown, the positioning disk 10 is also provided with a through groove, and completely coincides with the flow channel 9. In the initial state, the through groove on the positioning disk 10 and the flow channel 9 form a flow line. Since the two sides of the rotary disk 603 are provided, that is, two flow lines, the rotary disk 603 is accurately sent to the two sides of the center of the positioning disk 10 as the driving chain 5 rotates. At this time, the positioning disk 10 can be driven to rotate at a fixed angle to drive the entire rotary disk 603 to rotate. The fixed angle rotation mentioned here is to facilitate the subsequent telescopic column 604 on the rotary disk 603 to be able to separate from the positioning disk 10 and enter the flow channel 9. Therefore, when the rotary disk 603 is rotated once, at the end, the through groove on the positioning disk 10 should continue to be connected with the flow channel 9 to avoid hindering the normal sliding of the rotary disk 603.

[0033] like Figure 7 As shown, the rotation of a single positioning disk 10 is controlled by an independent transmission assembly 11, so the two turntables 603 on both sides of the conveying shell 601 are independently controlled, so that the two turntables 603 on one side can rotate independently, as shown in FIG. Figure 6 As shown, the central axis of the second turntable 603 passes through the conveying shell 601 and is connected to the first turntable 602. The end surface of the first turntable 602 is not flush, but is arranged in a tangent surface. As for the first turntable 602 being fixed on one side, it moves up and down on one side when rotating. By utilizing the rotation of the first turntable 602, a sliding control telescopic mechanism 7 is installed at the bottom of the entire conveying shell 601;

[0034] like Figure 6As shown, the main body of the sliding control telescopic mechanism 7 is composed of an interpenetrating shell 701 and a suspension rod 703. A hanger 707 is fixed to the end of the suspension rod 703. Therefore, the adjustment of the position of the suspension rod 703 controls the height of the entire basket 13 on the electroplating tank group 1. For the position adjustment of the suspension rod 703, an upper pressure rod 702 is slidably connected on both sides thereof. A pawl 705 is movably connected to the side wall of the pressure rod 702. One side of the pawl 705 is abutted by a paddle and the other side is abutted by a ratchet sleeve 704. The ratchet sleeve 704 is composed of a ratchet and a gear. The gear side is unilaterally meshed with the suspension rod 703, and the ratchet side is abutted against the pawl 705. Figure 6 As shown, when the left pressure rod 702 moves downward, the pawl 705 abuts against the entire ratchet and drives it to rotate counterclockwise, and the counterclockwise rotation of the ratchet sleeve 704 pushes the entire suspension rod 703 downward through the gear, that is, the basket 13 at the end of the hanger 707 is brought into contact with the solvent in the electroplating tank assembly 1;

[0035] When the left pressure rod 702 is pressed down each time, it will be reset by the spring. When the right pressure rod 702 is squeezed, the entire ratchet sleeve 704 is driven to rotate clockwise, and the entire suspension rod 703 is driven to rise through the rotation of the gear, which is convenient for the subsequent translation of the basket 13 on the top of the electroplating tank group 1. Each time the ratchet sleeve 704 rotates, the position needs to be limited. For this purpose, an upper limit block 706 is installed on the inside of the entire interpenetrating shell 701. An upper spring is also provided at the bottom of the limit block 706. The limit block 706 abuts against the ratchet sleeve 704 to complete the position limit of the suspension rod 703 after a single adjustment.

[0036] like Figure 6 As shown, the turntables 602 installed on both sides are located in the conveying shell 601. When one side of the turntable 602 is selected to rotate, the pressure rod 702 abutting against its end surface moves up and down in a cycle, ultimately achieving the height adjustment of the basket 13 at the end of the hanger 707. The rotation control of the turntable 602 at a specific position depends on the load sensing component 605 on the conveying shell 601.

[0037] Example 2: Figure 6 As shown, a load sensing component 605 is also installed on one side of the conveying shell 601. A weighing sensor, an inclination sensor and a main controller are installed in the load sensing component 605. A scanner is also provided to identify a barcode setting at a specific position of the electroplating tank group 1. The barcode is identified to control the rotation of the entire drive chain 5. The weighing sensor is used to detect the weight of the basket 13 on the hanger 707. The inclination sensor is used to monitor whether the basket 13 on the hanger 707 is abnormally tilted during transportation. The monitoring data is synchronously sent to the load sensing component 605. The main controller is used to receive data from the sensing system, control the start and stop, speed and direction of the drive chain 5, and trigger an alarm based on the sensed abnormal data to remind maintenance personnel to correct the position of the basket 13 in time.

[0038] Since the electroplating process is carried out on the same conveyor line, and the process durations in different slots are different, after the shortest process on the single-side drive chain 5 is completed, the next process cannot be carried out and it is necessary to wait for the previous process to be completed, which increases the overall electroplating time. For this reason, multiple slots are opened on the entire electroplating tank group 1, and the slots are of different sizes. The slot area is divided according to the duration of each process, similar to slot No. 1 for pickling, slot No. 2 for rinsing, and slot No. 3 for electroplating. The electroplating time is the longest, followed by pickling. Therefore, the area of ​​the pickling tank and the electroplating tank is expanded, and the drive chain 5 drives each basket 13 to move. The baskets 13 for electroplating and pickling remain in the slots and are not lifted, leaving space for the drive chain 5 to move for the material to be cleaned in the rinsing tank.

[0039] At the same time, since the number of installed sensing and conveying components is much larger than the sliding and telescopic mechanism 7, when electroplating operations are performed on devices of different shapes and sizes, the basket 13 can be designed to have hooks on both sides, which are hung on the hangers 707 on both sides respectively. Since the height of the single-sided hanger 707 can be adjusted automatically, the immersion angle of the entire basket 13 can be controlled to adapt to the electroplating of devices of different shapes, avoiding different devices and different positions of devices in the same basket 13 from not being effectively electroplated. The height of both sides of the basket 13 can be flexibly controlled, which can achieve more flexible transportation regulation. Compared with the use of an independent intelligent suspension trolley or a friction wheel drive trolley, although the positioning accuracy is high, it can be independently controlled and the flexibility is good, it lacks dynamic adjustment of the electroplating position of large devices in the slot, and the overall cost is relatively high.
