[0002] Inductors are an indispensable part of the circuit, and after the production of inductors, they need to be functionally tested to avoid product failure. The first traditional testing method is to manually place the products individually or in groups on different test benches, and then use different testers to test the inductors for different items to detect the various performance of the inductors.

[0048] Specifically, Figure 2 As shown, the loading conveying mechanism 2 includes a first conveying base plate 201 fixed on the frame 1, a first conveying side plate 202 is fixed on each of the front and rear sides of the first conveying base plate 201, a first supporting plate 203 is provided between the two first conveying side plates 202, first transmission roller assemblies 204 are provided on both sides of the first supporting plate 203, a first conveying belt 205 is wound around the first transmission roller assembly 204, a first guide plate 206 is provided on the inner side of each first conveying side plate 202, the first conveying belt 205 is located between the two first guide plates 206, the first conveying belt 205 includes an upper conveying belt and a lower conveying belt, the first supporting plate 203 is located between the upper conveying belt and the lower conveying belt, and is close to the lower end of the upper conveying belt, for supporting the upper conveying belt, ensuring that the upper conveying belt is always in a linear conveying state; the first transmission roller assembly 204 is driven by the first driving motor 207, and then drives the first conveying belt 205 to move. When performing an inductance test, the product to be tested is manually placed on the first conveying belt 205 of the feeding conveying mechanism 2 , and the product to be tested is guided by the first guide plate 206 and conveyed to the material dividing and distance changing mechanism 3 .

[0049] It can be understood that in other embodiments of the present invention, the first conveying bottom plate 201 and the first conveying side plate 202 can be connected in an integral manner, which can be collectively referred to as the first conveying side plate, so that the first conveying side plate is directly fixedly connected to the frame 1, and the purpose is to provide a transmission space for the first conveying belt 205, all of which fall within the protection scope of the present invention.

[0050] Specifically, Figure 3 , Figure 4As shown, the material dividing and variable pitch mechanism 3 includes a material dividing unit, a material pushing unit and a variable pitch unit, wherein the material dividing unit includes a material dividing bottom plate 301 fixedly arranged on the frame 1, a material dividing support plate 302 fixedly arranged on the material dividing bottom plate 301, and a material dividing plate 303 arranged on the material dividing support plate 302, a material dividing guide support plate 304 is fixedly arranged on the material dividing plate 303, a material dividing guide cylinder 305 is fixedly arranged on the material dividing guide support plate 304, a material dividing guide plate 306 is fixed at the lower end of the telescopic rod of the material dividing guide cylinder 305, a material dividing guide plate 306 is fixed on the material dividing plate 303, and a feed channel 3031 interconnected with each other and a first discharge channel 3032 connected to the feed channel 3031 are provided on the material dividing plate 303, and the material dividing guide plate 306 is located above the feed channel 3031, and is driven by the material dividing guide cylinder 305 to move up and down.

[0051] Further, the pushing unit includes a pushing support plate 307 fixedly arranged on the material distribution bottom plate 301, a pushing cylinder 308 arranged on the pushing support plate 307, and a pushing transition plate 309 arranged at the lower end of the piston rod of the pushing cylinder 308. The pushing transition plate 309 is provided with a first pushing rod 310, a second pushing rod 311 and a third pushing rod 312 from left to right. The three pushing rods are arranged in parallel and spaced apart, and are arranged perpendicularly to the feed channel 3031, and are used to push the product intervals on the feed channel 3031 to the first discharge channel 3032. Of course, in other embodiments of the present invention, four pushing rods, five pushing rods, six pushing rods, etc. can be arranged according to actual test needs to achieve pushing multiple test products to the first discharge channel 3032 at one time, and completing a test of more products at the same time.

[0052] Furthermore, the variable pitch unit includes a first variable pitch cylinder 313 fixedly arranged on the material distribution bottom plate 301, and a first cylinder connecting plate 314 arranged on the piston rod of the first variable pitch cylinder 313, the first cylinder connecting plate 314 performs telescopic movement in the discharge direction of the first discharge channel 3031; a second variable pitch cylinder 315 is fixedly arranged on the first cylinder connecting plate 314, a second cylinder connecting plate 316 is arranged on the piston rod of the second variable pitch cylinder 315, a buffer support plate 317 is arranged on the second cylinder connecting plate 316, a buffer 318 is arranged on the buffer support plate 317, a first variable pitch support side plate 319 and a second variable pitch support side plate 320 are respectively arranged on the left and right sides of the second cylinder connecting plate 316, a variable pitch guide rod 321 is fixedly arranged between the first variable pitch support side plate 319 and the second variable pitch support side plate 320, and a variable pitch fixed sliding block 322 is fixed on the inner side of the first variable pitch support side plate 319 , the first variable distance moving slider 323, the second variable distance moving slider 324 and the third variable distance moving slider 325 are slidably provided on the variable distance guide rod 321 from left to right through linear bearings in sequence, the variable distance fixed slider 322, the first variable distance moving slider 323, the second variable distance moving slider 324 and the third variable distance moving slider 325 are connected by a scissor-type connecting rod 326, and variable distance plates 327 are equidistantly provided on the first variable distance moving slider 323, the second variable distance moving slider 324 and the third variable distance moving slider 325, and the third variable distance cylinder 328 is fixedly provided on the second variable distance supporting side plate 320, and the piston rod of the third variable distance cylinder 328 is fixedly connected to the third variable distance moving slider 325, and the scissor-type connecting rod 326 is driven to contract and open by the third variable distance cylinder 328, thereby realizing the variable distance; during the variable distance process, the product to be tested contacts the right end surface of the variable distance plate 327, and the variable distance plate pushes the product to be tested to move in the conveying direction to realize the variable distance. Preferably, a buffer block 329 is also provided on the third variable pitch movable slider 325, and the buffer block 329 is arranged opposite to the buffer 318. The interaction between the buffer block 329 and the buffer 318 realizes stable variable pitch, and prevents the right end face of the product to be tested from being separated from the variable pitch plate 327 due to inertia during the variable pitch process, so that the product to be tested can be positioned close to the edge after the variable pitch action is completed. Specifically, after the product to be tested is variable pitch, the distance between two adjacent variable pitch plates 327 is greater than the length of the single product to be tested in the variable pitch direction, so the product to be tested can shake between the variable pitch plates 327, and the buffer block 329 and the buffer 318 can buffer and decelerate, preventing the product to be tested from being separated from the variable pitch plate 327 due to inertia. It should be noted that the number of multiple variable pitch movable sliders of the present invention should be greater than or equal to the number of push rods, so that the products pushed to the discharge channel by the push rod are received by the variable pitch plate and variable pitched. In addition, in other embodiments of the present invention, multiple variable-distance movable sliders may be provided to achieve spacing of multiple products at one time, which all fall within the protection scope of the present invention and will not be described in detail in the present invention.

[0053] Specifically, when the loading and conveying mechanism 2 conveys the product to be tested to the feeding channel 3031 on the dividing plate 303, after the feeding channel 3031 is full of material, the dividing guide cylinder 305 contracts to drive the dividing guide plate 306 to rise, and the telescopic rod of the pushing cylinder 308 extends to drive the first pushing rod 310, the second pushing rod 311 and the third pushing rod 312 to push the first product, the third product and the fifth product from left to right to the first discharging channel 3032 on the dividing plate 303, and the dividing guide cylinder 305 drives the dividing guide plate 306 to descend, and the second variable distance The cylinder 315 extends to drive the variable pitch plate 327 to enter the first discharge channel 3032, and the third variable pitch cylinder 328 extends to push the third variable pitch moving slider 325, and the variable pitch plate 327 pushes the first product, the third product, and the fifth product to be equidistantly contracted in the conveying direction through the transmission of the scissor-type connecting rod 326. Then, the first variable pitch cylinder 313 extends to move the first product, the third product, and the fifth product that have been equidistantly contracted in the conveying direction for a distance. After the feed channel 3031 of the dividing plate 303 is full of material, the above-mentioned partial actions are repeated to push out the first product. , the third product, and the fifth product are transferred to the first discharge channel 3032, and the third variable pitch cylinder 328 extends to push the third variable pitch sliding block 325 and the transmission of the scissor-type connecting rod 326 to make the variable pitch plate 327 push the first product, the third product, and the fifth product to be equidistantly contracted in the conveying direction. Through the above actions, 6 products to be tested with small pitches are completed on the first discharge channel 3032 of the dividing plate 303; the present invention divides and changes the pitch of the continuous and mutually contacting products to be tested conveyed by the first conveyor belt 205 into products to be tested with small pitches through the dividing and variable pitch mechanism 3. For example, considering the length tolerance of the products to be tested in the conveying direction, three products are selected for one material division and distance change, and the material division and distance change of 6 products to be tested are completed through two actions; the purpose of the material division and distance change of the present invention is that the contact between products will affect some test items. Through the material division and distance change, there are small intervals between products, which is convenient for accurate testing of inductance, and multiple products can be tested at one time, which greatly improves the test efficiency; and in the process of changing the distance into a small spacing, the cumulative error of the products to be tested in the conveying direction can be eliminated, and the length of subsequent workstations and racks in the product conveying direction can be reduced. It can be understood that a single product to be tested is assembled and bonded by a base plate, a cover plate and pins. During the assembly process, an error of ±0.5 will be generated in the conveying direction of the product. The more the number of products to be tested accumulates, the greater the accumulated error will be. In this embodiment, the variable distance plate 327 contacts the right end face of the product to be tested for variable distance positioning. The accumulated error generated when conveying multiple products to be tested will be positioned during the variable distance process. The accumulated error of multiple products to be tested will be converted into the manufacturing error of a single product, ensuring that the material shifting paddle 408 in the subsequent material shifting mechanism is accurately inserted into the small spacing of the product to be tested and will not be inserted on the product to be tested, resulting in material shifting failure or rubbing against the product to be tested to damage the appearance quality of the product to be tested.

[0054] Specifically, Figure 5 As shown, the material moving mechanism 4 includes a material moving base plate 401 fixed on the frame 1, a first material moving support plate 402 arranged on the material moving base plate 401, and a second material moving support plate 403 arranged on the first material moving support plate 402, wherein the second material moving support plate 403 is provided with a first linear motion component 404, and the first linear motion component 404 includes a first synchronous belt transmission component 4041 and a first linear guide rail 4042, a material moving cylinder connecting plate 405 is driven by the first synchronous belt transmission component 4041 to slide and connect to the first linear guide rail 4042, a material moving cylinder 406 is fixedly connected to the material moving cylinder connecting plate 405, a material moving rod 407 is provided at the lower end of the material moving cylinder piston rod, and a plurality of material moving paddles 408 are equidistantly provided at the lower end of the material moving rod 407 from left to right, and the plurality of material moving paddles 408 are located above the first discharge channel 3032, and move left and right along the first linear guide rail 4042 driven by the first synchronous belt transmission component 4041. Specifically, after the material-splitting and pitch-changing mechanism 3 completes the 6 products to be tested with small pitches, the material-moving paddle 408 is inserted into the small pitch of the 6 products to be tested with small pitches through the material-moving cylinder 406, and then the material-moving paddle 408 is driven by the first linear moving component 404 to drive the 6 products to be tested to move toward the testing mechanism 5. After the material-splitting and pitch-changing mechanism 3 completes the second group of 6 products to be tested with small pitches, the material-moving mechanism 4 repeats the above action. It can be known that in order to smoothly insert the material-moving paddle 408 into the small pitch of the products to be tested, the distance of the small pitch is greater than the thickness of the material-moving paddle 408.
