Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic door technology, and in particular to automatic door systems. Background Technology
[0002] In modern industrial production, surface treatment of copper-plated substrates is a key step in improving their performance and extending their service life. Surface treatment of copper-plated substrates is achieved by using volatile chemicals. However, the volatility of these chemicals increases costs, and the evaporation of the liquid can also corrode equipment.
[0003] In existing technologies, copper-plated substrates are directly placed in an open chemical solution for surface treatment. This open solution can evaporate and corrode other components. To prevent this evaporation, a sealed door is typically used. However, this door structure involves numerous mechanical components (transmission elements such as motors and cylinders, sensors for control, a cover to ensure the door's seal, and hinges for flexible space utilization). Furthermore, in factories, multiple sets of open chemical solutions and sealed door structures are used for mass production, consuming significant space and mechanical components, and requiring substantial space for maintenance, thus increasing costs. To address these issues, this application proposes an automatic door system. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic door system. By moving the cover plate down, the bottom of the cover plate can abut against the top of the fixed frame to complete the sealing of the processing tank. This structure is equivalent to the function of a "door", which can prevent the evaporation of the liquid medicine and replace the cumbersome mechanical parts set on the sealing door. Except for the time when the product is put in and discharged, the door is always in the closed state in this device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic door system includes a processing box, a fly bar and a fixture are provided above the processing box, a base plate is mounted on the fixture, the fly bar and the fixture are fixedly connected, a cover plate is fixedly connected to the top of the fly bar, a clamping mechanism is provided between the base plate and the fixture, a processing groove is provided through the top of the processing box, and a fixing frame is fixedly connected to the top of the processing box.
[0007] Preferably, the clamping mechanism includes a plurality of clamps disposed on and fixedly connected to the fixture, the plurality of clamps clamping the top of the substrate, and a plurality of clamps fixedly connected to the fixture, the plurality of clamps clamping the left, right and lower ends of the substrate.
[0008] Preferably, the fixture includes a fixed block fixedly connected to the jig, a rotating shaft rotatably connected to the fixed block, a clamping rod fixedly connected to the outer wall of the rotating shaft, two torsion springs sleeved on the outer wall of the rotating shaft, each torsion spring having its two ends fixedly connected to the fixed block and the clamping rod respectively, and a handle installed at the end of the clamping rod away from the substrate.
[0009] Preferably, the bottom of the fixture is fixedly connected to two contact blocks, and the inner wall of the processing box is fixedly connected to two support blocks. The top of each of the two support blocks is equipped with a waterproof sensing element that cooperates with the contact blocks.
[0010] Preferably, a sealing ring is fixedly connected to the bottom of the cover plate, and the sealing ring is configured to cooperate with the top of the fixed frame.
[0011] Preferably, the flybar is positioned directly above the processing tank, and the cover plate is slightly larger than the fixed frame.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. The cover plate on the fixture is slightly larger than the top fixing frame of the processing box, and the bottom of the cover plate is equipped with a sealing ring. When the fixture moves the substrate into the processing box, the cover plate and the top of the fixing frame are tightly pressed together with the sealing ring, which effectively prevents the liquid in the processing box from leaking out of the processing tank. In addition, except for the time when the substrate is put in and out, the processing tank is always in a closed state, which not only avoids the waste of liquid, but also ensures the safety of the production environment and the health of the staff, while stabilizing the processing technology and improving product quality.
[0014] 2. By lowering the cover plate on the substrate and fixture, the bottom of the cover plate can abut against the top of the fixing frame, thus sealing the processing tank. This structure acts like a "door," preventing the evaporation of the liquid and replacing the cumbersome mechanical parts on the sealing door in the original technology. Except for the time when products are fed in and discharged, the door is always closed in this device. By replacing the traditional sealing door, this device can reduce mechanical parts, reduce maintenance elements, and significantly reduce the space required, thereby improving the production efficiency of the equipment.
[0015] In summary, by moving the cover plate down, the bottom of the cover plate can be brought into contact with the top of the fixed frame, thus sealing the treatment tank. This structure acts like a "door," preventing the evaporation of the liquid and replacing the cumbersome mechanical parts on the sealing door. Except for the time when the product is fed in and discharged, the door is always closed in this device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-5 The automatic door system includes a processing box 1. A fly bar 3 and a fixture 9 are provided on the top of the processing box 1. The fixture 9 is used to clamp the substrate 2. The position of the fixture 9 ensures that the substrate 2 can smoothly enter the processing box 1 for processing. The substrate 2 is installed on the fixture 9. The fly bar 3 and the fixture 9 are fixedly connected. A cover plate 8 is fixedly connected to the top of the fly bar 3. The top of the cover plate 8 is connected to an external hydraulic rod to control the lifting and lowering of the fixture 9.
[0024] A clamping mechanism is provided between the substrate 2 and the fixture 9. The clamping mechanism includes multiple fixing clamps 4 fixedly connected to the fixture 9. The multiple fixing clamps 4 clamp the top of the substrate 2. The fixing clamps 4 limit and fix the top of the substrate 2 to ensure the stability of the substrate 2 in the vertical direction. Multiple clamps 5 are fixedly connected to the fixture 9. The clamps 5 further enhance the fixing effect on the substrate 2. The clamps 5 and the fixing clamps 4 work together to achieve all-round clamping and fixing of the substrate 2. The clamps 5 include a fixing block 12 fixedly connected to the fixture 9. A rotating shaft is rotatably connected to the fixing block 12. A clamping rod 13 is fixedly connected to the outer wall of the rotating shaft. The shaft allows the clamping rod 13 to rotate flexibly to achieve clamping and releasing operations. Two torsion springs 14 are sleeved on the outer wall of the shaft. The torsion springs 14 provide clamping force to the clamping rod 13, so that it can maintain a stable clamping state after clamping the substrate 2. The two ends of each torsion spring 14 are fixedly connected to the fixing block 12 and the clamping rod 13 respectively. A handle 15 is installed on the end of the clamping rod 13 away from the substrate 2. Multiple clamps 5 are evenly distributed and clamp the left, right and lower ends of the substrate 2. The handle 15 makes it convenient for the operator to operate the clamping rod 13. By applying force to the handle 15, the rotation of the clamping rod 13 is controlled, thereby realizing the clamping and releasing of the substrate 2.
[0025] Two contact blocks 10 are fixedly connected to the bottom of the fixture 9. The contact blocks 10 are used to trigger the waterproof sensor 11 to detect the position of the fixture 9 and the substrate 2. Two support blocks are fixedly connected to the inner wall of the processing box 1. The top of each support block is equipped with a waterproof sensor 11 that cooperates with the contact block 10. The waterproof sensor 11 can be a waterproof pressure sensor. When the contact block 10 contacts the waterproof sensor 11, it can detect that the fixture 9 and the substrate 2 have reached the designated position and transmit the signal to the outside to control the hydraulic rod to stop, so as to achieve precise control of the position of the fixture 9 and the substrate 2. At this time, the top of the cover plate 8 and the fixed frame 7 are tightly sealed. The processing box 1 uses volatile liquid medicine. The cooperation between the fixed frame 7 and the cover plate 8 seals the liquid medicine in the processing box 1, which prevents the liquid medicine in the processing box 1 from evaporating and also protects the external equipment from corrosion.
[0026] A processing groove 6 is provided through the top of the processing box 1. A fixing frame 7 is fixedly connected to the top of the processing box 1. A fixture 9 is located directly above the processing groove 6. The processing groove 6 provides a channel for the substrate 2 and the fixture 9 to enter and exit the processing box 1. The size of the cover plate 8 is slightly larger than the size of the fixing frame 7. A sealing ring is fixedly connected to the bottom of the cover plate 8. The sealing ring is set to cooperate with the top of the fixing frame 7. After the fixture 9 and the substrate 2 enter the processing box 1, the sealing ring is tightly fitted with the top of the fixing frame 7 to play a sealing role. The sealing ring is designed to prevent corrosion and prevent the liquid (volatile) in the processing box 1 from leaking from the processing groove 6 during the processing.
[0027] In this invention, multiple fixtures 9 are installed on the production line (the top of the fixture 9 is equipped with a chain conveyor structure for transporting the fixture 9; this technology is existing and will not be described in detail here). The operator places the substrate 2 onto the fixture 9, clamps the top of the substrate 2 with multiple clamping clips 4, and clamps the left, right, and bottom ends of the substrate 2 with multiple clamps 5, thus completing the clamping and fixing between the substrate 2 and the fixture 9. When the fixture 9 moves the clamped substrate 2 to its destination, the hydraulic rod connected to the top of the cover plate 8 drives the fixture 9 and substrate 2 downwards until the substrate 2 and fixture 9 pass through the processing tank 6 and enter the processing box 1. At this time, the two contact blocks 10 contact the waterproof sensor 11, and the waterproof sensor 11 senses... When subjected to pressure, a signal is transmitted to the outside to control the hydraulic rod to stop (this technology is existing and will not be described in detail here). At this time, the top of the fixed frame 7 and the bottom of the cover plate 8 are exactly abutted to seal the processing tank 6 and prevent the liquid from leaking out of the processing box 1. After the substrate 2 is surface treated, the substrate 2 and the fixture 9 can be lifted and reset by the external hydraulic rod. The fixture 9 is transported by the production line and the next fixture 9 will immediately enter the processing box 1. Therefore, except for the time when the substrate 2 is put in and taken out, the processing tank 6 is always in a closed state. As long as the production line is running, the substrate 2 and the fixture 9 will continuously enter and exit, thus playing a sealing role (sealing the volatile liquid). It will only be briefly opened when the substrate 2 enters and exits.
