Description

Technical Field

[0001] The invention relates to the technical field of electronic component production, and in particular to an automatic loading and unloading device for heat treatment. Background Art

[0002] Currently, traditional metallized film capacitors are directly sprayed with pure zinc or zinc-tin alloy after winding to form an overall electrode surface, and then welded.

[0003] In the prior art, due to the limitation of welding process, most capacitor electrode materials are zinc and tin-zinc alloys, but zinc and tin alloys have the disadvantages of high resistivity and low thermal conductivity. The resistivity of zinc and tin are 59nΩ.m and 11.4nΩ.m respectively, and the thermal conductivity of zinc and tin are 112W / mk and 64W / mk respectively. When a large current passes through the capacitor terminal electrode, charge carriers (electrons or holes) are generated and captured by the trap bands of the dielectric and the electrode to form trapped charges, which leads to the destruction of the material structure, limits the service life of the capacitor, and also limits the development of higher current of the capacitor. At the same time, the film capacitor will generate a lot of heat during use, which will cause certain damage to the film capacitor.

[0004] Moreover, the metallized film capacitors commonly used on the market use a heat treatment method during the processing process to cause the polypropylene film to shrink in the radial and transverse directions, squeezing out the water vapor and air remaining in the film during winding, so as to improve the tightness between the film layers of the capacitor core after winding.

[0005] At present, conventional heat treatment is preheating and pressing first, and then heat treatment is carried out in an atmospheric oven or a vacuum oven. When the operator places the storage box loaded with capacitors in the atmospheric oven for heat treatment, the operator needs to carry the storage box manually, which is labor-intensive and the speed of carrying and transporting the storage box is slow.

[0031] Example

[0032] Please refer to Figure 1-Figure 7 shown.

[0033] The present invention provides a heat treatment automatic loading and unloading device, such as Figure 1 , Figure 2As shown, it includes a rectangular chassis 1 with a large accommodating space inside. The chassis 1 is welded by plates and steel frames. The clamping mechanism for clamping the storage box is convenient for placing the operator on the operating platform 2 to clamp the capacitor storage box that has not been dried for transportation, so as to facilitate subsequent operations. The top of the chassis 1 is fixed with an operating platform 2 by countersunk bolts to strengthen the structural strength of the chassis 1. Two guide frames 3 are installed on the operating platform 2. The two guide frames 3 are parallel to each other and perpendicular to the operating platform 2. The two are fixedly connected by bolts or welding; guide channels 11 are opened on the side walls of the guide frames 3 in the vertical direction. The cross-section of the guide channels 11 is rectangular. A displacement seat 12 is slidably provided in the guide channel 11. The displacement seat 12 is a rectangular slider. The side wall of the displacement seat 12 abuts against the inner wall of the guide channel 11 to prevent the displacement seat 12 from deflecting when performing lifting and lowering movements; the clamping mechanism is installed on the two displacement seats 12, and a lifting mechanism for driving the displacement seat 12 to move in the vertical direction is provided in the guide frame 3, so that the displacement seat 12 placed in the clamping position can be lifted. The storage box in the mechanism is lifted to a suitable height, which speeds up the loading and unloading speed of the storage box and avoids the temperature in the baking box from dropping sharply, which may cause the problem of difficulty in subsequent heating. An installation groove is provided on the operating platform 2, and a first conveyor belt 8 is rotatably provided in the installation groove. A part of the first conveyor belt 8 is placed in the clamping area of ​​the clamping mechanism. The storage box can be orderly transferred to the clamping area of ​​the clamping mechanism through the first conveyor belt 8, so that the storage box to be dried can be quickly transferred to different levels of the drying box 7, thereby accelerating the operation efficiency of the present structure. A first driving mechanism is provided in the chassis 1 to drive the first conveyor belt 8 to rotate. The first driving mechanism is composed of a motor and a reducer, which can ensure that the first conveyor belt 8 can transport the storage box to the clamping area of ​​the clamping mechanism at a constant speed. A conveying assembly for conveying the storage box is provided in the clamping mechanism, which is convenient for conveying the storage box placed between the clamping mechanisms to different levels of the drying box 7 or transferring the storage boxes in different levels of the drying box 7 to the clamping area of ​​the clamping mechanism, thereby accelerating the operation efficiency of the present structure.

[0034] In some technical solutions of the present invention, the clamping mechanism includes two clamping arms arranged in pairs, and the two displacement seats 12 are fixedly installed with guide seats 22 by bolts. The guide seats 22 are arranged on the displacement seat 12 in the horizontal direction. The two guide seats 22 are slidably provided with wedge-shaped guide strips 23 to prevent the guide strips 23 from sliding out of the slide grooves of the groove bodies on the guide seats 22. A mounting seat 24 is provided between the guide strips 23 and the corresponding clamping arms. The mounting seat 24 is fixedly connected with the guide strips 23 and the clamping arms by bolts, which is convenient for later maintenance; the side walls of the guide seats 22 are provided with guide strips 23 and guide strips 23. The first push rod 21 connected to the strip 23 is an electric push rod. The body of the first push rod 21 is fixedly connected to the guide seat 22 through a socket, and the telescopic end of the first push rod 21 is fixedly connected to the mounting seat 24 through bolts. In this way, the relative distance between the two clamping arms can be controlled by the two first push rods 21, so as to clamp storage boxes of different sizes to increase the adaptability of the structure. When the storage box is introduced into the drying box 7, the two clamping arms can be controlled to move away from each other by a certain distance to avoid the problem of interference with the movement of the storage box due to excessive clamping of the storage box.

[0035] In some technical schemes of the present invention, the lifting mechanism includes a plurality of first gearing blocks 13 hinged to each other in sequence, a plurality of second gearing blocks 15 hinged to each other in sequence, and a top block 16, the second gearing blocks 15 and the side walls which are away from each other from the first gearing blocks 13 are provided with rectangular tooth grooves 14, the plurality of first gearing blocks 13 in the form of chain links and the plurality of second gearing blocks 15 in the form of chain links are all penetrated in the chassis 1, a transmission gear 19 is rotatably provided in the chassis 1, a part of the transmission gear 19 is embedded in the tooth groove 14, the top block 16 is hinged to the first gearing block 13 and the second gearing block 15, the top block 16 displacement seat 12 is fixedly connected by bolts, and a transmission gear 19 is installed in the chassis 1. Any two adjacent first gearing blocks 13 are connected by a connecting frame 17, and the connecting frame 17 is rotatably connected to the first gearing block 13 by a pin, so that the plurality of first gearing blocks 13 in the form of a chain link have a relatively free movement space during the subsequent movement; any two adjacent second gearing blocks 15 are also connected by a connecting frame 17, and the connecting frame 17 is rotatably connected to the second gearing block 15 by a pin, so that the plurality of second gearing blocks 15 in the form of a chain link have a relatively free movement space during the subsequent movement; and a receiving channel for receiving the first gearing block 13 or the second gearing block 15 is provided in the chassis 1, and the receiving channel is formed by splicing two parallel plate structures The cage-like structure is not shown in the drawings; it is used to guide the first gear block 13 or the second gear block 15 to move in a predetermined direction. The working principle of the lifting mechanism is as follows: in the initial state, most of the chain-like first gear blocks 13 and the chain-like second gear blocks 15 are placed in the chassis 1, and the parts where the chain-like first gear blocks 13 and the chain-like second gear blocks 15 are connected to the top block 16 are meshed with each other and placed on the outside of the chassis 1; when the driving motor drives the transmission gear 19 to make a circular motion, the transmission gear 19 will gradually drive the second gear block 15 to gradually move out of the chassis 1. At this time, the chain-like first gear blocks 13 and the chain-like second gear blocks 1 5, when the first engaging block 13 and the second engaging block 15 are meshed with each other in sequence, and the convex portion of any second engaging block 15 is placed between the convex portions of any two adjacent first engaging blocks 13; the plurality of first engaging blocks 13 in a chain shape move out of the chassis 1 together with the second engaging blocks 15, and the displacement seat 12 can be lifted by using the above structure, and the movement distance of the displacement seat 12 on the guide frame 3 can be adjusted; the convex portion of any second engaging block 15 is placed between the convex portions of any two adjacent first engaging blocks 13, and the above structure can also play a self-locking role, thereby preventing the clamping mechanism for clamping the storage box from suddenly falling back under the lifting of the above structure, so as to ensure the stability of the structure during movement.

[0036] In some technical solutions of the present invention, it further includes a limiting cylinder 18 with a rectangular cross-section. The limiting cylinder 18 is sleeved on a chain link structure formed by the meshing of a plurality of first engaging blocks 13 and a plurality of second engaging blocks 15, and is adapted to the above structure. The limiting cylinder 18 is installed on the top of the chassis 1 and is in communication with it. The provided limiting cylinder 18 can guide the problem of separation of the chain link structure formed by the meshing of a plurality of first engaging blocks 13 and a plurality of second engaging blocks 15.

[0037] In some technical solutions of the present invention, a limiting groove is vertically opened on the inner side wall of the guiding channel 11, and a limiting block 20 connected to the displacement seat 12 is slidably arranged in the limiting groove. Through the above structure, the displacement seat 12 can be guided to move in the guiding channel 11 along a predetermined direction in the vertical direction, improving the stability of the operation of this structure.

[0038] In some technical solutions of the present invention, the clamping arm includes a first support frame 4 and a second support frame 6. The first support frame 4 is connected to the mounting seat 24. An expansion frame 5 connected to the second support frame 6 is installed in the first support frame 4, and the expansion frame 5 is an electric telescopic rod. Through the above structure, after the support arm 12 is lifted to a certain height, the second support frame 6 in the support arm box can be pushed by the expansion frame 5 to move closer to or away from the drying box 7 until the second support frame 6 in the clamping arm overlaps or disengages from the layered plate of the drying box 7. In this way, the storage box can be transported to different hierarchical areas of the drying box 7 or the storage box in different hierarchical areas of the drying box 7 can be transferred to the clamping area of the clamping mechanism through the conveying component, accelerating the operation efficiency of this structure.

[0039] In some technical solutions of the present invention, there are two sets of conveying components, and the two sets of conveying components are respectively arranged on the opposite side walls of the two clamping arms.

[0040] In some technical solutions of the present invention, the conveying component includes two "C"-shaped mounting brackets 27, which are bent by a bending device. A guiding groove 26 is opened on the side wall of the first support frame 4. One of the mounting brackets 27 is slidably arranged in the guiding groove 26, and the other mounting bracket 27 is installed on the second support frame 6 by bolts. Mounting rollers 25 are rotatably arranged in the mounting brackets 27, and a second transmission belt 9 is sleeved between the two mounting rollers 25. A driving motor传动连接 to the mounting roller 25 is installed on the second support frame 6. In this way, the second transmission belt 9 can be driven to rotate independently by the mounting roller 25, so as to transport the storage box placed between the two clamping arms to different hierarchical areas of the drying box 7 or transfer the storage box in different hierarchical areas of the drying box 7 to the clamping area of the clamping mechanism, accelerating the operation efficiency of this structure.

[0041] In some technical solutions of the present invention, support plates 10 are installed on the opposite side walls of the two clamping arms, and the support plates 10 are located at the bottom ends of the first support frame 4 and the second support frame 6. They are used to prevent the storage box placed between the two clamping arms from slipping during transportation.

[0042] In some technical solutions of the present invention, a limit spring 28 connected to the mounting bracket 27 is provided in the guide groove 26. When the mounting bracket 27 slidably disposed in the guide groove 26 moves with the second conveyor belt 9 toward the direction of approaching the drying box 7 or moves away from the drying box 7, the second conveyor belt 9 can be kept relatively taut during the above movement process, thereby improving the stability of the device during operation.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
