Description

Technical Field

[0001] This utility model relates to the field of production and transportation line technology, and in particular to the assembly of an evaporator helium detection line. Background Technology

[0002] An evaporator is a device used to convert liquids into gases. Its core working principle is to use heat to convert liquids into vapor, thereby achieving purposes such as liquid concentration, drying, or separation. The basic principle of helium detection is based on the fact that ions with different mass-to-charge ratios have different deflection radii when moving in a plane perpendicular to a magnetic field, thus achieving the separation of dissimilar ions. After the evaporator is manufactured, a helium test is required. During the test, the workpiece is evacuated and then filled with helium gas at a certain pressure. The workpiece is surrounded by a vacuum chamber with a certain vacuum level, which is connected to the leak detection port of a helium mass spectrometer leak detector. If a leak is found in the workpiece, helium gas will enter the vacuum chamber through the leak and be captured by the helium mass spectrometer leak detector, displaying the leak rate. Currently, the helium detection production line for evaporators has a complex layout, occupies a large area, does not conform to workshop space planning, and has slow loading and unloading speeds. Placing materials into the vacuum chamber requires the use of robotic arms, increasing production line costs and failing to meet overall assembly cost requirements. Therefore, improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide an evaporator helium detection line assembly to address the above issues.

[0004] The evaporator helium detection line assembly includes a feeding elevator, a main conveyor line, several lifting machines, a detection transition line, several vacuum chambers, a chamber outlet line, a qualified product transition line, and a discharging elevator. The feeding elevator, main conveyor line, and discharging elevator are connected sequentially and arranged in a straight line. Several lifting machines are installed at intervals within the main conveyor line. Several detection transition lines are arranged side by side at intervals on one side of the main conveyor line, with their inlet ends corresponding to the lifting machines. The outlet ends of the detection transition lines are connected to the vacuum chambers one by one. The chamber outlet line is located on the side of the vacuum chamber away from the detection transition line. The outlet of the chamber outlet line is connected to the outlet end of the main conveyor line through the qualified product transition line.

[0005] Preferably, it also includes a non-conforming return line, which is parallel to the box-out line, and a corresponding lifting machine is installed in both the non-conforming return line and the box-out line.

[0006] Preferably, the non-conforming return line is connected to the feed end of the main conveyor line via a return transition line.

[0007] Preferably, the lifting machine includes a lifting cylinder, a mounting frame, a drive motor, a rotating shaft, and a conveyor belt assembly. The lifting cylinder is located below the mounting frame and its output end is connected to the mounting frame to drive the mounting frame to rise and fall.

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] like Figures 1-2 As shown, the evaporator helium detection line assembly includes a feeding elevator 1, a main conveyor line 2, several lifting machines 3, a detection transition line 4, several vacuum boxes 5, a box outlet line 6, a qualified product transition line 7, and a discharging elevator 8. The feeding elevator 1, the main conveyor line 2, and the discharging elevator 8 are connected sequentially and arranged in a straight line. Several lifting machines 3 are installed at intervals within the main conveyor line 2. Several detection transition lines 4 are arranged side by side at intervals on one side of the main conveyor line 2, with their inlet ends corresponding one-to-one with the lifting machines 3. The outlet ends of the detection transition lines 4 are connected one-to-one with the vacuum boxes 5. The box outlet line 6 is located on the side of the vacuum box 5 away from the detection transition lines 4. The outlet of the box outlet line 6 is connected to the outlet end of the main conveyor line 2 through the qualified product transition line 7. Specifically, in this embodiment, the loading elevator 1 is installed at the inlet of the main conveyor line 2, and the unloading elevator 8 is installed at the outlet of the main conveyor line 2. The main conveyor line 2 in this design adopts belt conveying. Several lifting machines 3 are set at intervals in the middle of the main conveyor line 2. The lifting machines 3 can lift the workpieces (not shown in the figure) passing on them, so that the workpieces are separated from the main conveyor line 2. The lifting machines 3 also have a lateral transport function, which can transport the workpieces laterally. The lateral transport direction is perpendicular to the transport direction of the main conveyor line 2. Using the lifting machines 3, the workpieces are transferred to the inspection transition line 4. Through the inspection transition line 4, the workpieces are transported one by one to the vacuum box 5 for vacuum helium inspection. If the workpiece is qualified, the workpiece is transported from the vacuum box 5 to the box exit line 6. The workpiece passes through the box exit line 6 and the qualified product transition line 7 in sequence, returns to the main conveyor line 2, and is finally unloaded by the unloading elevator 8. The entire production line is designed as an integrated layout, incorporating loading and unloading functions. It occupies a small area, requiring minimal workshop space. The layout is reasonable, and the lifting machine is integrated into the main conveyor line, eliminating the need for robotic arms and ensuring extremely smooth transitions between workpieces.

[0019] like Figures 1-2 As shown, it also includes a non-conforming return line 9, which runs parallel to the exit line 6. Both the non-conforming return line 9 and the exit line 6 are equipped with corresponding lifting machines 3. Specifically, when a workpiece fails the helium inspection in the vacuum chamber 5, the workpiece is on the exit line 6. The lifting machines 3 on the exit line 6 are correspondingly positioned to the outlet of the vacuum chamber 5, allowing the non-conforming workpiece to be directly transported to the non-conforming return line 9 via the lifting machines 3 on the exit line 6 for manual inspection and correction. This avoids the simultaneous output of non-conforming and conforming workpieces, preventing difficulties in separating them from the next production line and ensuring that the inspection meets standards.

[0020] like Figures 1-2 As shown, the non-conforming return line 9 is connected to the feed end of the main conveyor line 2 via a return transition line 91. Specifically, the returned workpiece is transferred back to the main conveyor line 2 via the return transition line 91, and then transported back to the vacuum chamber 5 for inspection via the lifting machine 3 inside the main conveyor line 2. This avoids removing non-conforming workpieces from the production line for inspection and improves overall work efficiency.

[0021] like Figures 1-3 As shown, the lifting machine 3 includes a lifting cylinder 31, a mounting frame 32, a drive motor 33, a rotating shaft 34, and a conveyor belt assembly 35. The lifting cylinder 31 is located below the mounting frame 32, and its output end is connected to the mounting frame 32, driving the mounting frame 32 to rise and fall. Two sets of conveyor belt assemblies 35 are installed side by side on the mounting frame 32 at intervals. The ends of the conveyor belt assemblies 35 are connected through the rotating shaft 34. The output end of the drive motor 33 is movably connected to the rotating shaft 34 through a belt. Specifically, when it is necessary to lift the workpiece, the output end of the lifting cylinder 31 extends, causing the overall height of the mounting frame 32 to rise. At this time, the drive motor 33 starts synchronously, and its output end drives the rotating shaft 34 to rotate through the belt. The two ends of the rotating shaft 34 are connected to the ends of the transmission belt group 35, which in turn drives the drive wheel at the end of the transmission belt group 35 to rotate, thereby driving the belt sleeved on the transmission belt group 35 to rotate. This allows the workpiece to be lifted and transported laterally, separating it from the original main conveyor line 2. The entire lifting machine 3 has a simple structure, low cost, and is extremely convenient to maintain.

[0022] like Figures 1-2As shown, several barriers 10 are horizontally arranged on the main conveyor line 2, the inspection transition line 4, and the non-conforming return line 9. The barriers 10 are arranged sequentially at intervals. Specifically, some barriers 10 are arranged one-to-one above the lifting machine 3. When a workpiece passes above the lifting machine 3, and the workpiece is transported at a relatively high speed on the production line, the workpiece may not be able to be lifted smoothly by the lifting machine 3, or the workpiece may become misaligned when being lifted. In this case, we need to use barriers 10 to temporarily block the workpiece, keeping it stationary on the production line, so that the lifting machine 3 can lift the workpiece in its original posture and transfer it to other production lines.

[0023] like Figure 4 As shown, the barrier 10 includes a crossbeam 101, a bracket 102, a drive cylinder 103, and a buffer wheel 104. The drive cylinder 103 is mounted on the crossbeam 101, and its output end passes through the crossbeam 101 and is connected to the bracket 102. The buffer wheel 104 is movably mounted on the bracket 102. Specifically, when it is necessary to block the workpiece, the drive cylinder 103 drives the bracket 102 to rise, causing the height of the buffer wheel 104 to rise synchronously. Because the buffer wheel 104 is movably mounted on the side top position of the bracket 102 via a pin, the front of the workpiece collides and abuts against the buffer wheel 104, thus blocking the workpiece. When it is necessary to release the workpiece, the drive cylinder 103 drives the bracket 102 to fall and reset, causing the height of the buffer wheel 104 to decrease. At this time, only the top arc surface of the buffer wheel 104 contacts the bottom of the workpiece, and the buffer wheel 104 can play the role of supporting the workpiece.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, 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.
