Description

Technical Field

[0001] This utility model relates to the field of relay brazing equipment technology, and in particular to an automatic rotary device for brazing high-voltage DC relays. Background Technology

[0002] Brazing of ceramic components for high-voltage DC relays involves melting solder at high temperatures in a vacuum or hydrogen-nitrogen mixed gas environment to weld the ceramic and metal parts together. This welding process requires a high degree of uniformity in ambient temperature.

[0003] In automated welding, products continuously enter the welding furnace of the welding equipment for welding. To ensure welding efficiency, the interval between products entering the furnace is minimized to improve welding efficiency. However, if the interval between products is too short, adjacent products can interfere with and affect the temperature uniformity within the furnace, leading to a decrease in welding yield. To balance welding efficiency with product yield, a dedicated person is assigned to adjust the interval between products at the welding equipment's loading port. However, the environment at the welding machine's loading port is harsh, the manual labor is intense, and errors are prone to occur, further impacting welding efficiency and yield.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic rotary device for high-voltage DC relay brazing, so as to quickly adjust the interval of products fed into the welding equipment.

[0006] The technical solution of this utility model is as follows:

[0007] An automatic rotary device for brazing high-voltage DC relays includes: a feeding conveyor mechanism; a high-speed conveyor mechanism connected to the feeding conveyor mechanism, wherein a first sensor is installed on the high-speed conveyor mechanism to monitor the presence or absence of products on the high-speed conveyor mechanism; an equidistant conveyor mechanism connected to the high-speed conveyor mechanism, wherein the output end of the equidistant conveyor mechanism is connected to the feeding position of the processing equipment; a second sensor is installed on the equidistant conveyor mechanism, wherein calibrated objects are equidistantly arranged on the conveying section of the equidistant conveyor mechanism, and the second sensor monitors the presence or absence of the calibrated objects; wherein a first lifting stop is provided between the feeding conveyor mechanism and the high-speed conveyor mechanism, and a second lifting stop is provided between the high-speed conveyor mechanism and the equidistant conveyor mechanism; the first sensor, the second sensor, the first lifting stop, and the second lifting stop are all connected to a control unit.

[0008] A further technical solution includes a material feeding and conveying mechanism connected to the material feeding position of the processing equipment, with a fixed obstruction at the output end of the material feeding and conveying mechanism.

[0009] A further technical solution is that the output end of the unloading conveyor is connected to the loading conveyor; the loading conveyor, the high-speed conveyor, the equidistant conveyor, the processing equipment, and the unloading conveyor form a closed loop.

[0010] The further technical solution is that the feeding conveyor adopts a powered roller conveyor, the high-speed conveyor adopts a belt conveyor, and the equidistant conveyor adopts a chain conveyor.

[0011] A further technical solution is that the calibration object is a fixed block, which is fixed on the conveyor chain of the equidistant conveyor structure.

[0012] A further technical solution is that the conveying speed of the high-speed conveying mechanism is five times that of the feeding conveying mechanism.

[0013] A further technical solution is that, within a fixed time period, the number of products conveyed by the equidistant conveying mechanism is equal to the number of products welded by the processing equipment.

[0014] A further technical solution is that both the first lifting block and the second lifting block include a cylinder. The extension and retraction of the cylinder drives the first lifting block and the second lifting block to rise and fall, so as to isolate the feeding conveying mechanism, the high-speed conveying mechanism and the equidistant conveying mechanism, or to connect the feeding conveying mechanism, the high-speed conveying mechanism and the equidistant conveying mechanism.

[0015] A further technical solution is that the first and second sensors are proximity sensors.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] (1) The high-voltage DC relay brazing automatic rotary device of this utility model is equipped with and connected to a feeding conveyor mechanism, a high-speed conveyor mechanism, and an equidistant conveyor mechanism to achieve automatic feeding. A first lifting stop is set between the feeding conveyor mechanism and the high-speed conveyor mechanism, and a second lifting stop is set between the high-speed conveyor mechanism and the equidistant conveyor mechanism. A first sensor and a second sensor are also set on the high-speed conveyor mechanism and the equidistant conveyor mechanism. During the feeding process, when the first sensor detects that there is no product on the high-speed conveyor mechanism, the first lifting stop is lowered, allowing a single product to enter the high-speed conveyor mechanism. The second sensor detects the position of the calibration object, causing the second lifting stop to be lowered, and the product on the high-speed conveyor mechanism enters the designated position on the equidistant conveyor mechanism, realizing the equidistant arrangement of products on the equidistant conveyor mechanism, thereby ensuring a constant interval between products entering the processing equipment, uniform feeding, and ensuring welding product efficiency and yield.

[0018] (2) Furthermore, a feeding conveyor mechanism, a loading conveyor mechanism, a high-speed conveyor mechanism, an equidistant conveyor mechanism, processing equipment, and a feeding conveyor mechanism are also provided to form a closed loop. This circular arrangement of the high-voltage DC relay brazing automatic rotary device allows products to circulate within the ring layout, facilitating centralized loading and unloading and improving production efficiency. Moreover, the ring layout allows for a more compact arrangement of equipment and personnel, saving space. Attached Figure Description

[0025] Figure 1 The diagram shows the main structural view of the automatic rotary device for brazing high-voltage DC relays of this utility model. Figure 2This diagram shows a partially enlarged view at point A of the automatic rotary brazing device for high-voltage DC relays of this invention. Please refer to it. Figure 1 and Figure 2 An automatic rotary device for brazing high-voltage DC relays includes a feeding conveyor mechanism 1, a high-speed conveyor mechanism 3, and an equidistant conveyor mechanism 5, enabling automatic feeding. The high-speed conveyor mechanism 3 is connected to the feeding conveyor mechanism 1 and is equipped with a first sensor 31 that monitors the presence or absence of a product 6 on the high-speed conveyor mechanism 3. The equidistant conveyor mechanism 5 is connected to the high-speed conveyor mechanism 3, and its output end is connected to the feeding position of a processing device 7. The equidistant conveyor mechanism 5 is equipped with a second sensor 51, and calibration objects 52 are equidistantly arranged on its conveying section, with the second sensor 51 monitoring the presence or absence of the calibration objects 52. A first lifting stop 2 is provided between the feeding conveyor mechanism 1 and the high-speed conveyor mechanism 3, and a second lifting stop 4 is provided between the high-speed conveyor mechanism 3 and the equidistant conveyor mechanism 5. The first sensor 31, the second sensor 51, the first lifting stop 2, and the second lifting stop 4 are all connected to a control unit. The control unit can be a programmable logic controller (PLC). During the feeding process, when the first sensor 31 detects that there is no product 6 on the high-speed conveyor 3, the first lifting barrier 2 descends, allowing a single product 6 to enter the high-speed conveyor 3. The second sensor 51 detects the position of the calibration object 52, causing the second lifting barrier 4 to descend, allowing the product 6 on the high-speed conveyor 3 to enter a designated position on the equidistant conveyor 5. This achieves equidistant arrangement of the products 6 on the equidistant conveyor 5, ensuring a constant interval between the products 6 entering the processing equipment 7, uniform feeding, and guaranteeing the efficiency and yield of the welded products 6.

[0026] Among them, the first sensor 31 and the second sensor 51 are commercially available Keyence Q5 wired proximity sensors.

[0027] Please refer to Figure 1 It also includes a feeding conveyor mechanism 8, which is connected to the feeding position of the processing equipment 7. The output end of the feeding conveyor mechanism 8 is provided with a fixed stop 81. The processed workpiece is blocked by the fixed stop 81 and stays on the feeding conveyor mechanism 8 for easy collection.

[0028] Preferably, the output end of the unloading conveyor 8 is connected to the loading conveyor 1. The loading conveyor 1, the high-speed conveyor 3, the equidistant conveyor 5, the processing equipment 7, and the unloading conveyor 8 form a closed loop. This circular arrangement of the high-voltage DC relay brazing automatic rotary device allows the product 6 to circulate within the ring layout, facilitating centralized loading and unloading and improving production efficiency. Furthermore, the ring layout allows for a more compact arrangement of equipment and personnel, saving space.

[0029] Please refer to Figure 1 and Figure 2The feeding conveyor 1 uses a powered roller conveyor, which is suitable for various types and specifications of materials and is easy to integrate with automation systems for intelligent management. It also features a buffer device to reduce collision damage to product 6 during transport. The high-speed conveyor 3 uses a belt conveyor, which has a large contact area with product 6, increasing friction and allowing product 6 to be quickly carried away by the acceleration section. The equidistant conveyor 5 uses a chain conveyor, which allows for easy setting of markers 52 to separate items.

[0030] Furthermore, the calibration object 52 is a fixed block, which is fixed on the conveyor chain of the equidistant conveying structure. The position of the calibration object 52 is detected by the second sensor 51, which causes the second lifting stop 4 to drop. The product 6 on the high-speed conveying mechanism 3 enters the designated position on the equidistant conveying mechanism 5, thereby realizing the equidistant arrangement of the product 6 on the equidistant conveying mechanism 5.

[0031] Furthermore, the conveying speed of the high-speed conveying mechanism 3 is five times that of the feeding conveying mechanism 1, so that after the first lifting barrier 2 is opened, the first product 6 that enters the high-speed conveying mechanism 3 from the feeding conveying mechanism 1 can be separated from the adjacent product 6 to quickly pass over the first lifting barrier 2, which makes it convenient to store a single product 6 on the high-speed conveying mechanism 3.

[0032] Within a fixed time period, the number of products 6 conveyed by the equidistant conveying mechanism 5 is equal to the number of products 6 welded by the processing equipment 7, ensuring that the products 6 enter the processing equipment 7 evenly.

[0033] Please refer to Figure 1 and Figure 2 Both the first lifting stop 2 and the second lifting stop 4 include cylinders. The extension and retraction of the cylinders drive the first lifting stop 2 and the second lifting stop 4 to rise and fall, thereby isolating or connecting the feeding conveyor mechanism 1, the high-speed conveyor mechanism 3, and the equidistant conveyor mechanism 5. The cylinder structure is relatively simple, easy to install and maintain, and has a fast response speed, making it suitable for quickly isolating and connecting various conveying mechanisms.

[0034] The specific workflow of this utility model is as follows:

[0035] The operator or the feeding mechanism places product 6 on the feeding conveyor 1, and product 6 moves towards the high-speed conveyor 3 along the conveying direction of the feeding conveyor 1.

[0036] During this process, the first sensor 31 detects that there is no product 6 on the output end of the high-speed conveying mechanism 3. The first lifting component lifts and connects the feeding conveying mechanism 1 and the high-speed conveying mechanism 3. The product 6 at the output end of the feeding conveying mechanism 1 moves into the high-speed conveying mechanism 3. The product 6 on the high-speed conveying mechanism 3 moves at high speed and quickly creates a gap with the product 6 on the feeding conveying mechanism 1, and then moves to the output end of the high-speed conveying mechanism 3.

[0037] At this time, the first sensor 31 detects that there is a product 6 at the output end of the high-speed conveyor 3. The first lifting component moves up and down into the gap between the products 6, separating the feeding conveyor 1 and the high-speed conveyor 3. At this time, a product 6 moves into the high-speed conveyor 3. Until the second sensor 51 detects that the calibration object 52 passes through the detection area, the second lifting block 4 moves up and down to connect the high-speed conveyor 3 and the equidistant conveyor 5. The product 6 at the output end of the high-speed conveyor 3 moves into the equidistant conveyor 5. The above product 6 conveying steps are repeated. The products 6 are arranged at equal intervals along the calibration object 52 on the equidistant conveyor 5 and evenly conveyed to the processing equipment 7.

[0038] The product 6, which has been processed by the processing equipment 7, moves out along the unloading conveyor 8 and is eventually blocked and piled up on the unloading conveyor 8 by the fixed block 81 until the operator or the unloading mechanism unloads the product 6 from the unloading conveyor 8.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
