Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve assembly technology, and in particular relates to a testing device for electromagnetic valves after assembly. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices and are basic components for controlling fluids in automation. In the solenoid valve assembly and production workshop, after the solenoid valves are assembled, they need to undergo performance testing and marking identification processes, which specifically involve electrical performance testing, shape testing, and airtightness testing.

[0003] In existing technologies, the integration level between related testing processes is low, and the layout of related testing equipment is simply arranged according to the process steps, resulting in low space utilization. Based on this, the applicant has designed the layout of related testing equipment to reduce the number or space occupation of some, such as material moving mechanisms, to achieve a dense layout of integrated equipment, reduce the transfer time between processes, and improve production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for solenoid valves after assembly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a testing device for an assembled solenoid valve, comprising a workbench, on which an airtightness testing component and a marking and scanning component are sequentially arranged; an airtightness testing positioning fixture is provided at the airtightness testing component; a marking and scanning positioning fixture 23 is provided at the marking and scanning component; and a product loading and unloading fixture and a product unloading area are also provided on the workbench.

[0006] The workbench is also equipped with a material transfer mechanism, which includes a material picking component and a drive component that drives the material picking component to move.

[0007] The product loading and positioning fixture, the air tightness detection and positioning fixture, the marking and scanning positioning fixture 23, and the product unloading point are located on the same straight line a. After the material is picked up from the product loading and positioning fixture, the material picking component passes through the air tightness detection and positioning fixture, the marking and scanning positioning fixture 23, and the product unloading point in sequence.

[0008] Preferably, the product unloading area includes a qualified product unloading area and a non-qualified product unloading area, and the product loading positioning fixture, airtightness detection positioning fixture, marking and scanning positioning fixture 23, qualified product unloading area and non-qualified product unloading area are located on the same straight line.

[0009] Preferably, there are two airtightness testing components, which are respectively placed at both ends of a base. The line connecting the two airtightness testing components is perpendicular to the straight line a. The base is provided with two airtightness testing positioning fixtures, which move between one airtightness testing component and the straight line a.

[0010] Preferably, the drive component one includes a horizontal linear movement component one, a vertical linear movement component one installed at the working end of the horizontal linear movement component one, and a horizontal linear movement component two fixed at the working end of the vertical linear movement component one, wherein the material picking component one is installed at the working end of the horizontal linear movement component two.

[0011] Preferably, the workbench is further provided with a rotating disk and a first rotary drive assembly for driving the rotating disk to rotate. There are several product loading and positioning fixtures, all of which are set on the rotating disk. The workbench is also provided with at least one of an electrical performance detection assembly, an electrical conduction detection assembly, and a product shape detection assembly arranged around the rotating disk. The first rotary drive assembly can drive the product loading and positioning fixtures along a straight line a and stop at the intersection of the straight line a closest to the airtightness detection positioning fixture and the path of the product loading and positioning fixture.

[0012] Preferably, the workbench is further provided with a product loading fixture and a material transfer component two. The material transfer component two includes a material picking component two and a drive component two for controlling the material picking component two to move from the product loading fixture to the product loading positioning fixture.

[0013] Preferably, the workbench is further provided with a material transport component, which is equipped with a number of trays, and each tray is provided with a product loading fixture.

[0014] Preferably, a second rotary drive assembly is also installed on the workbench, and the marking and scanning positioning fixture 23 is disposed at the rotating end of the second rotary drive assembly.

[0015] The beneficial effects of this utility model are as follows: This solution sets the airtightness detection positioning fixture, the label scanning positioning fixture, the product loading positioning fixture, and the product unloading point on the same straight line, and realizes the transfer of materials between the above-mentioned positions through a material transfer mechanism. This achieves a tight layout of related components, effectively reduces the transfer time between processes, and improves production efficiency.

[0016] In particular, by setting both the qualified product unloading point and the unqualified product unloading point on line a, the integrated effect of this solution design is further demonstrated;

[0017] Because the airtightness test takes a relatively long time, two airtightness test components and two airtightness test positioning fixtures are set up, with the two airtightness test components placed on both sides of line a respectively. The two airtightness test positioning fixtures alternately place the untested products at one airtightness test component for testing, and alternately transfer the tested products to line a, thereby further improving the overall efficiency.

[0018] Among them, the design of horizontal linear motion component one, vertical linear motion component one and horizontal linear motion component two, compared with the single horizontal linear motion component one, will reduce the cost and effectively reduce the space occupied.

[0019] In this layout, by setting up a rotating disk and surrounding the electrical performance testing component, the power-on testing component, and the product shape testing component with related testing equipment, this approach can effectively save overall design costs and reduce the space occupied in the layout.

[0020] The design of the transport components and pallets makes the entire equipment more automated;

[0021] The second rotary drive component drives the marking and scanning positioning fixture 23 to move and rotate, enabling marking to be performed at different positions on the product. Attached Figure Description

It also has a pressure head and a vertical linear moving component for controlling the lifting and lowering of the pressure head. In this component, the two are respectively named vertical novel moving component four and pressure head four. The difference is that one is a power-on testing head 85 and the other is an electrical performance testing head. The electrical performance testing component 7 does not require a displacement detection sensor, so it is not shown in the figure in this article.

[0041] The product shape detection component 9 includes a detection camera, which is used to detect whether the shape of the solenoid valve terminal meets the requirements, wherein the shape of the solenoid valve can be referenced. Figure 2 The terminal of the part clamped by the material handling component 2 1003 is located on the side of the overall product;

[0045] Working principle and process:

[0046] In operation, the complete equipment structure of this solution involves the material transport component 11 driving the pallet 12 to load products. Subsequently, the material transfer component 2 10 transfers the products from the product loading fixture 13 to the product loading positioning fixture 6 on the rotating disk 5. Next, the rotating disk 5 rotates into the electrical performance testing component 7. The vertical linear movement component 4 102 drives the pressure head 4 to descend, pressing the product firmly into the product loading positioning fixture 6. Then, the horizontal linear movement component 4 105 drives the electrical performance testing head to insert into the solenoid valve and connect to its upper terminal for testing. After completion, the relevant components reset, and the rotating disk 5 moves the product to the electrical performance testing component 7 for testing. The operation procedure of this component can be referenced from that of the electrical performance testing component 7. After the electrical performance test is completed, the relevant components reset, and the rotating disk 5 moves the product to the product shape detection component 9. The detection phase mainly takes pictures of the product terminals for testing. Then, the rotating disk 5 moves the product to line a. At this time, the material transfer mechanism 1 4 controls... The material handling component 45 places the product onto the airtightness detection positioning fixture 104. The airtightness detection positioning fixture 104 is moved to below the airtightness detection head 103 on one side by the horizontal linear movement component 4 105. The vertical linear movement component 4 102 drives the airtightness detection head 103 to descend for detection. During this process, the horizontal linear movement component 4 105 on the other side drives another airtightness detection positioning fixture 104 to line a, waiting for the material handling component 45 to place the newly moved material from the rotating disk 5. The material is placed on top of the airtightness testing head 103 and then moved to the bottom of another airtightness testing head 103 for testing. At the same time, the material that has been tested will be transferred to the straight line a on the previous airtightness testing positioning fixture 104. Then, the material transfer mechanism 14 will move the material to the marking and scanning positioning fixture 23. After marking and scanning, it will be determined whether all the test items are qualified. If they are qualified, they will be moved to the qualified product unloading point 3 by the material transfer mechanism 14. If they are unqualified, they will be moved to the unqualified product unloading point 3 by the material transfer mechanism 14.
