Description

Technical Field

[0001] This utility model belongs to the field of relay testing technology and relates to a relay packaging inspection tool. Background Technology

[0002] Relay packaging inspection refers to the inspection and testing of the quality and performance of the relay's external enclosure (package) to ensure it meets design standards and can operate reliably in various environments. If the packaging is substandard, even if the relay's internal functions are normal, it will quickly fail in actual use. Therefore, packaging inspection is a crucial step in ensuring the long-term reliability, safety, and consistency of relays. Currently, relay packaging inspection mainly relies on manual inspection using general-purpose measuring tools or simple, single-function inspection fixtures, which suffers from low efficiency, poor consistency, and the potential to damage products. Therefore, designing a relay packaging inspection fixture is essential. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a relay packaging inspection fixture.

[0004] The objective of this utility model can be achieved through the following technical solution: A relay packaging inspection fixture, comprising a base, characterized in that the base is provided with a placement groove for matching the shape of the relay, the bottom of the placement groove is provided with a positioning pin corresponding to the mounting hole at the bottom of the relay, the bottom of the placement groove is also provided with a groove, in which a micro-motion probe and a detection probe are alternately arranged, the micro-motion probe and the detection probe are electrically connected to an adapter, the adapter is connected to an external measuring device through an electrical interface, and a positioning clamping mechanism is provided at a corresponding position above the base, the positioning clamping mechanism comprising a mounting base, on which a pneumatic push rod is vertically mounted, and a pressure block is mounted on the rod of the pneumatic push rod.

[0005] The working principle of this invention is as follows: During operation, the relay to be tested is first placed in the placement slot on the base and precisely positioned using a positioning pin. Then, the positioning and clamping mechanism is activated, and a pneumatic push rod drives the pressure block to press down, stably clamping the relay. At the moment of clamping, all the relay pins simultaneously sink into the bottom groove and contact the micro-motion probe and the detection probe respectively. The micro-motion probe array automatically determines whether the pin coplanarity is qualified by detecting whether each pin is triggered simultaneously; while the detection probe forms a reliable electrical connection with the relay pins. The status signals and electrical signals generated by all probes are collected through an adapter and transmitted to external measuring equipment and control system via an electrical interface, thus simultaneously completing a comprehensive, rapid, and automated inspection of the relay's package dimensions and electrical performance within a single clamping operation.

[0006] The tip of the micro-motion probe is slightly higher than the bottom surface of the placement groove.

[0007] The above structure ensures that all pins can reliably trigger the probes simultaneously when the relay is clamped.

[0008] An insulating buffer pad is bonded to the bottom surface of the pressure block. The insulating buffer pad is made of rubber or engineering plastic.

[0009] The above structure is used to protect the surface of the relay housing from scratches during compression.

[0010] Both the base and the mounting bracket are provided with mounting holes.

[0011] Using the above structure, the base and mounting seat are fixed through the mounting holes.

[0012] The inlet of the placement slot is chamfered.

[0013] The above structure facilitates the insertion of the relay.

[0014] A pressure sensor is also installed inside the pressure block.

[0015] The above structure is used for displacement sensors or pressure sensors to detect whether the pressing block is pressed into place.

[0016] Compared with existing technologies, this relay packaging inspection fixture has the following advantages: Through integrated and automated design, this utility model realizes "one-time clamping and synchronous completion" of multi-item inspection of relay packaging, which significantly improves inspection efficiency and consistency, while perfectly integrating into modern intelligent production lines.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-2As shown, this relay packaging inspection fixture includes a base 1. The base 1 has a placement groove that matches the shape of the relay. The bottom of the placement groove has a positioning pin 2 corresponding to the mounting hole 12 on the bottom of the relay. The bottom of the placement groove also has a groove 3. A micro-motion probe 4 and a detection probe 5 are alternately arranged in the groove 3. The micro-motion probe 4 and the detection probe 5 are electrically connected to an adapter 6. The adapter 6 is connected to an external measuring device through an electrical interface 7. A positioning clamping mechanism is provided at a corresponding position above the base 1. The positioning clamping mechanism includes a mounting base 8. A pneumatic push rod 9 is vertically mounted on the mounting base 8. A pressure block 10 is installed on the rod of the pneumatic push rod 9.

[0022] Specifically, the fixture includes a base 1 serving as a support foundation. The base 1 is preferably made of a rigid metal material to ensure its stability and prevent deformation during operation. On the top surface of the base 1, a placement groove is machined to match the shape of the relay. The shape of the placement groove is similar to the outline of the relay under test, which can initially limit the relay. In order to achieve precise positioning of the relay, positioning pins 2 are provided at the bottom of the placement groove. The positions of these positioning pins 2 correspond to the standard mounting holes 12 on the bottom of the relay. When the relay is placed in the groove, the positioning pins 2 can be inserted into its mounting holes 12, thereby eliminating displacement deviation in any direction and ensuring that the placement position is unique and accurate each time. To facilitate the placement of the relay, a guide chamfer is also provided at the inlet of the placement groove.

[0023] At the bottom of the placement slot, a recess 3 is provided. Two types of probes with different functions are alternately arranged in this recess 3: micro-motion probes 4 and detection probes 5. The top of the micro-motion probes 4 is set slightly higher than the bottom surface of the placement slot to ensure that all pins of the relay can simultaneously and reliably press against the top of the micro-motion probes 4 when the relay is pressed. These micro-motion probes 4 essentially form a detection array for automatically determining the coplanarity of the relay pins. The detection probes 5 are preferably high-performance spring probes used to form a stable electrical connection with the relay pins when pressed. The wires of all these probes are connected to an adapter 6, which can be an integrated printed circuit board. Its function is to neatly route and converge the signal lines of all probes. The adapter 6 is finally connected to external measuring equipment through a standard electrical interface 7 located on the side of the base 1.

[0024] Above the base 1, a positioning and clamping mechanism is provided at the corresponding placement slot. This mechanism includes a mounting base 8 fixed to the base 1 by a support column. A pneumatic push rod 9 is vertically mounted on the mounting base 8, with its piston rod extending downwards and a pressure block 10 installed at its end. To protect the fragile surface of the relay housing during clamping, an insulating buffer pad 11 made of rubber or engineering plastic is bonded to the bottom surface of the pressure block 10. In addition, a pressure sensor 13 can be installed inside the pressure block 10 to detect whether the clamping force is sufficient, thereby achieving precise process control. Both the base 1 and the mounting base 8 are provided with standard mounting holes 12, facilitating the fixing of the entire fixture to a workbench or automated production line.

[0025] In this invention, each micro-motion probe 4 includes an independent micro-motion switch; the micro-motion probe 4 is electrically connected to a signal processing circuit, which is configured to output a uniform signal with qualified coplanarity when and only when all micro-motion probes 4 are triggered simultaneously.

[0026] In this invention, the detection probe 5 guides the electrical signal to the standard electrical interface 7 on the side through the adapter 6 inside the tooling. The inspector only needs to connect this interface and the external tester with a cable to complete insulation, withstand voltage and other tests.

[0027] The adapter 6 in this utility model adopts an existing PCB board structure product.

[0028] In this utility model, the pneumatic push rod 9 is connected to an external air supply device.

[0029] The pressure sensor 13 in this invention uses an existing product.

[0030] The working principle of this invention is as follows: During operation, the relay to be tested is first placed in the placement slot on the base 1 and precisely positioned using the positioning pin 2. Then, the positioning clamping mechanism is activated, and the pneumatic push rod 9 drives the pressure block 10 to press down, stably clamping the relay. At the moment of clamping, all the relay pins simultaneously sink into the bottom groove 3 and contact the micro-motion probe 4 and the detection probe 5 respectively. The micro-motion probe 4 array automatically determines whether the pin coplanarity is qualified by detecting whether each pin is triggered simultaneously. The detection probe 5 forms a reliable electrical connection with the relay pins. All status signals and electrical signals generated by the probes are collected through the adapter 6 and transmitted to external measuring equipment and control system via the electrical interface 7, thus simultaneously completing a comprehensive, rapid, and automated inspection of the relay's package dimensions and electrical performance within a single clamping operation.

[0031] In this invention, the various mechanisms are connected and driven using existing technologies, and synchronous control is achieved through a control panel.

[0032] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
