Description

Technical Field

[0001] This utility model relates to the field of multi-station electronic component testing fixtures, and in particular to a multi-station electronic component testing fixture. Background Technology

[0002] A multi-station electronic component test fixture consists of a test fixture body, a clamping device, a pin plate, an anti-slip sleeve, and a handle. It is mainly used for testing electronic components and is quite common in the existing technology.

[0003] Existing technologies, such as the utility model patent with publication number CN219266350U, disclose a test fixture with multi-station testing function. This patent employs a mounting base and a positioning frame. A horizontal plate is fixedly connected to the upper front end of the mounting base, and side plates are fixedly connected to both the front and rear ends of the horizontal plate. Limiting components are provided inside the side plates, and a limiting stop plate is fixedly connected to the side of the electric telescopic rod near the central axis of the horizontal plate. This test fixture with multi-station testing function, through the large-volume horizontal plate, allows the storage plate formed by the horizontal plate and side plates to simultaneously accommodate multiple PCB boards during use. The purpose of having multiple stations on the storage plate is to allow operators to simultaneously load and unload multiple PCB boards onto the inner side of the storage plate during PCB board sampling inspection. This reduces the number of loading and unloading operations, improves PCB board testing efficiency, and facilitates the use of the test fixture.

[0004] The inventors discovered in their daily work that the replacement of ejector plates is cumbersome because existing ejector plates are fixed to the test fixture body with multiple bolts. Furthermore, during the replacement process, personnel need to use screwdrivers and other tools to rotate each bolt one by one to replace the ejector plate. This operation method is very cumbersome and leads to low work efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing ejector plate is fixed to the test fixture body by multiple bolts, and the replacement of the ejector plate requires personnel to use screwdrivers and other tools to rotate each bolt one by one. This operation method is very cumbersome and leads to low work efficiency. Therefore, a multi-station electronic component test fixture is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-station electronic component testing fixture, including: a testing fixture body, a disassembly structure, and a replacement structure. Two clamping devices are mounted on the upper surface of the testing fixture body, and a handle is installed inside each clamping device. An anti-slip sleeve is mounted on the arc surface of the handle via the replacement structure. Two ejector plates are mounted on the upper surface of the testing fixture body via the disassembly structure, and an electronic component body is disposed inside each ejector plate. The disassembly structure is provided on the upper surface of the testing fixture body, and includes eight positioning holes, four limiting holes, and four connecting brackets. Four connecting brackets are fixedly connected to the test fixture body. Two limiting holes are opened on the ejector plate, and four positioning holes are opened on the ejector plate. A limiting rod is slidably connected to the inner wall of the positioning hole. The limiting rod is fixedly connected to the test fixture body. A fixing rod is fixedly connected to the inner wall of the connecting bracket. A rotating plate is rotatably connected to the arc surface of the fixing rod. An insert rod is slidably connected to the inner wall of the rotating plate. A spring is sleeved on the arc surface of the insert rod. The two ends of the spring are fixedly connected to the insert rod and the rotating plate, respectively. A connecting plate is fixedly connected to the side of the rotating plate near the ejector plate. The insert rod is slidably connected to the limiting hole.

[0007] The effect achieved by the above components is as follows: when personnel need to replace the ejector plate, they can move the two insert rods to slide the rods out of the inner wall of the limiting hole, then rotate the two connecting plates until the connecting plates are away from the ejector plate, and then move the ejector plate until the limiting rod slides out of the inner wall of the positioning hole. This makes it convenient for personnel to replace the ejector plate and improves the work efficiency of personnel.

[0008] Preferably, a pull ring is fixedly connected to the end of the insertion rod away from the limiting hole, and the pull ring has a circular cross-section.

[0009] The effect achieved by the above components is that the pull ring makes it easy for personnel to move the plug, which can improve the ease of operation for personnel.

[0010] Preferably, a guide block is fixedly connected to the upper end of the limiting rod.

[0011] The effect achieved by the above components is that the guide block can guide the limiting rod, making it convenient for personnel to slide the limiting rod into the inner wall of the positioning hole.

[0012] Preferably, the rotating plate is made of stainless steel and has a rectangular cross-section.

[0013] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the plate from deforming during short-term use.

[0014] Preferably, the surface of the grip is provided with a replaceable structure, the replaceable structure including a retaining ring, a connecting groove and a fixing post. The retaining ring is fixedly connected to the grip, the connecting groove is opened on the anti-slip sleeve, the fixing post is fixedly connected to the grip, a baffle is rotatably connected to the arc surface of the fixing post, a coil spring is sleeved on the arc surface of the fixing post, the two ends of the coil spring are fixedly connected to the baffle and the fixing post respectively, and two auxiliary blocks are fixedly connected to the side of the baffle away from the grip.

[0015] The effect achieved by the above-mentioned components is that when the anti-slip sleeve wears out after long-term use and needs to be replaced, the operator can rotate the two auxiliary blocks to rotate the baffle to the appropriate position, and then move the anti-slip sleeve until it slides off the surface of the handle, thus facilitating the replacement of the anti-slip sleeve and improving the operator's work efficiency.

[0016] Preferably, the inner wall of the auxiliary block is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the auxiliary block.

[0017] The effect achieved by the above components is that the anti-slip groove can increase the friction between the personnel's hands and the auxiliary block, and can prevent the personnel from slipping when moving the auxiliary block.

[0018] Preferably, an auxiliary rod is slidably connected to the inner wall of the baffle, and an insertion hole is provided on the inner wall of the handle.

[0019] The aforementioned components achieve the following effect: they can assist in positioning the baffle and prevent the coil spring from rebounding during the replacement of the anti-slip sleeve.

[0020] Compared with related technologies, the multi-station electronic component testing fixture provided by this utility model has the following beneficial effects:

[0021] By setting up a disassembly structure, when personnel need to test electronic components of other sizes, they can easily replace the ejector plate through the disassembly structure, thereby speeding up the replacement of the ejector plate, improving personnel work efficiency and the applicability of the test fixture body.

[0022] By setting up a replacement structure, when personnel need to replace damaged anti-slip covers, the replacement structure can facilitate the replacement of the anti-slip covers, thereby speeding up the replacement process and improving personnel work efficiency. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figure 1This utility model provides a multi-station electronic component testing fixture, comprising: a testing fixture body 1, a disassembly structure 3, and a replacement structure 4. Two clamping devices 2 are installed on the upper surface of the testing fixture body 1, and a handle 8 is installed inside the clamping device 2. An anti-slip sleeve 7 is installed on the arc surface of the handle 8 through the replacement structure 4. Two ejector plates 5 are installed on the upper surface of the testing fixture body 1 through the disassembly structure 3. An electronic component body 6 is provided inside the ejector plate 5. The disassembly structure 3 is provided on the upper surface of the testing fixture body 1, and the replacement structure 4 is provided on the surface of the handle 8.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4 The disassembly structure 3 includes eight positioning holes 301, four limiting holes 302, and four connecting brackets 305. The four connecting brackets 305 are fixedly connected to the test fixture body 1. Two limiting holes 302 are opened on the ejector plate 5, and four positioning holes 301 are opened on the ejector plate 5. The inner wall of the positioning hole 301 is slidably connected to the limiting rod 303, which is fixedly connected to the test fixture body 1. The inner wall of the connecting bracket 305 is fixedly connected to the fixing rod 306. The arc surface of the fixing rod 306 is rotatably connected to the rotating plate 307. The inner wall of the rotating plate 307 is slidably connected to the insertion rod 309. The arc surface of the insertion rod 309 is fitted with a spring 310. The two ends of the spring 310 are fixedly connected to the insertion rod 309 and the rotating plate 307, respectively. The side of the rotating plate 307 near the ejector plate 5 is fixedly connected to the connecting plate 308. The insertion rod 309 is slidably connected to the limiting hole 302. When the ejector plate 5 needs to be replaced, the operator can move the two insert rods 309, causing them to slide out of the inner wall of the limiting hole 302. Then, the operator can rotate the two connecting plates 308 until they move away from the ejector plate 5. Finally, the operator can move the ejector plate 5 until the limiting rod 303 slides out of the inner wall of the positioning hole 301. This facilitates the replacement of the ejector plate 5 and improves the operator's work efficiency. A pull ring 311 with a circular cross-section is fixedly connected to the end of the insert rod 309 away from the limiting hole 302. The pull ring 311 facilitates the movement of the insert rod 309 and improves the operator's ease of operation. A guide block 304 is fixedly connected to the upper end of the limiting rod 303. The guide block 304 guides the limiting rod 303, allowing personnel to easily slide the limiting rod 303 into the inner wall of the positioning hole 301. The rotating plate 307 is made of stainless steel and has a rectangular cross-section. The stainless steel plate has high strength and good wear resistance, which can prevent the rotating plate 307 from deforming during short-term use.

[0035] In the embodiments of this utility model, please refer to Figures 5 to 7The replacement structure 4 includes a retaining ring 41, a connecting groove 42, and a fixing post 48. The retaining ring 41 is fixedly connected to the handle 8. The connecting groove 42 is formed on the anti-slip sleeve 7. The fixing post 48 is fixedly connected to the handle 8. A baffle 43 is rotatably connected to the arc surface of the fixing post 48. A coil spring 49 is sleeved on the arc surface of the fixing post 48. The two ends of the coil spring 49 are fixedly connected to the baffle 43 and the fixing post 48, respectively. Two auxiliary blocks 44 are fixedly connected to the side of the baffle 43 away from the handle 8. When the anti-slip sleeve 7 wears out after long-term use and needs to be replaced, the operator can rotate the two auxiliary blocks 44 to rotate the baffle 43 to a suitable position. Then, the operator can move the anti-slip sleeve 7 until it slides off the surface of the handle 8, which facilitates the replacement of the anti-slip sleeve 7 and improves the operator's work efficiency. Several anti-slip grooves 45 are formed on the inner wall of the auxiliary block 44. The several anti-slip grooves 45 are evenly formed on the auxiliary block 44. The anti-slip groove 45 increases the friction between the user's hand and the auxiliary block 44, preventing slippage during movement. An auxiliary rod 46 is slidably connected to the inner wall of the baffle 43, and an insertion hole 47 is provided on the inner wall of the handle 8. This achieves the effect of assisting in positioning the baffle 43 and prevents the coil spring 49 from rebounding during replacement of the anti-slip sleeve 7.

[0036] The working principle of the multi-station electronic component testing fixture provided by this utility model is as follows: When personnel need to test the electronic component body 6, they place the electronic component body 6 inside the ejector plate 5, so that the ejector pins inside the ejector plate 5 contact the electronic component body 6. Then, the personnel move the handle 8 to cause the clamping device 2 to squeeze the electronic component body 6, preventing it from moving. When personnel need to replace the ejector plate 5, they can first use the two pull rings 311 to move the insertion rod 309 away from the limiting hole 302. The pull rings 311 facilitate the movement of the insertion rod 309, improving the ease of operation. Then, the insertion rod 309 drives the spring 310 to stretch until the insertion rod 309 slides out of the inner wall of the limiting hole 302. The operator rotates the two connecting plates 308, causing them to rotate away from each other. The connecting plates 308 drive the rotating plate 307 to rotate away from the ejector plate 5. The rotating plate 307 then drives the spring 310 and the insert rod 309 to rotate away from the ejector plate 5, until the connecting plates 308 are far from the upper surface of the ejector plate 5. The rotating plate 307 is made of stainless steel, which has high strength and good wear resistance, preventing deformation of the rotating plate 307 during short-term use. Then, the operator moves the ejector plate 5 upwards until the limiting rod 303 and the guide block 304 completely slide out of the inner wall of the positioning hole 301. The guide block 304 guides the limiting rod 303, making it easy for the operator to slide the limiting rod 303 into the inner wall of the positioning hole 301.

[0037] In addition, when personnel need to replace the anti-slip sleeve 7, they can first rotate the two auxiliary blocks 44. The two auxiliary blocks 44 drive the baffle 43 to rotate, causing the baffle 43 to rotate towards the insertion hole 47. The baffle 43 drives the auxiliary rod 46 to rotate towards the insertion hole 47. The baffle 43 also drives the coil spring 49 to coil up until the auxiliary rod 46 corresponds to the insertion hole 47. Then, the personnel move the auxiliary rod 46 until it slides into the inner wall of the insertion hole 47. Then, the personnel move the anti-slip sleeve 7 away from the retaining ring 41 until the anti-slip sleeve 7 completely slides out of the surface of the handle 8. The anti-slip groove 45 can increase the friction between the personnel's hand and the auxiliary blocks 44, preventing the personnel from slipping during the movement of the auxiliary blocks 44. The auxiliary rod 46 and the insertion hole 47 can assist in positioning the baffle 43, preventing the coil spring 49 from rebounding during the replacement of the anti-slip sleeve 7.

[0038] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
