[0002] As a key link in the electronics manufacturing industry, the importance of circuit board processing is self-evident. The circuit board processing process includes raw material preparation, material inspection, circuit production, drilling and plating, component welding and surface treatment, etc., which will form a stable circuit board for actual use.

[0003] In the process of raw material preparation, it is necessary to ensure that the quality of raw materials such as substrate materials and copper foil meets the standards to avoid processing defects caused by material problems. The flatness of the substrate material is particularly important. If there are abnormal protrusions and deformations on the substrate material, it will inevitably have an adverse effect on the processing accuracy, component installation, welding quality and overall performance of the circuit board. Therefore, in the process of circuit board processing, the deformation problem of the substrate material must be highly valued. However, in the existing technology, most of them adopt the method of direct observation with the naked eye to observe whether the circuit board is deformed. The detection method of direct observation with the naked eye is very prone to deviations and has poor accuracy. Summary of the invention

[0026] like Figure 1-3 and Figure 7-10 As shown:

[0027] A testing device comprises a base plate 201 and a slide rail 302, wherein a rectangular frame 101 is slidably connected to the base plate 201, a pressure plate 102 is slidably connected to the rectangular frame 101, a sliding seat 601 is slidably connected to the slide rail 302, a detection rod 602 is slidably connected to the sliding seat 601, an arc chamfer 106 is provided on the pressure plate 102, a first compression spring is fixedly connected between the pressure plate 102 and the rectangular frame 101, a second compression spring is fixedly connected between the sliding seat 601 and the detection rod 602, a first motor is fixedly connected to the slide rail 302, a first lead screw is fixedly connected to the output shaft of the first motor, the first lead screw is threadedly connected to the slide seat 601, and a first electric push rod capable of pushing the rectangular frame 101 to slide is fixedly connected to the pressure plate 102.

[0028] The substrate raw material of the circuit board is placed on the bottom plate 201. Then, according to whether the size of the substrate matches the size of the bottom plate 201, it can be accurately determined whether the length and width of the substrate meet the target production requirements. If the substrate can be fully attached to the upper side of the bottom plate 201, the rectangular frame 101 can be operated to slide downward on the bottom plate 201. During the sliding process of the rectangular frame 101, the pressing plate 102 will first contact the upper surface of the substrate. Then, as the rectangular frame 101 continues to slide downward, the pressing plate 102 will overcome the elastic force of the first compression spring on the rectangular frame 101. Adaptive sliding occurs. When the rectangular frame 101 slides to the lowest position within the sliding range, the upper end of the pressing plate 102 should be able to coincide with the upper end of the rectangular frame 101. When the sliding operation of the rectangular frame 101 is completed, the staff can observe whether the upper end of the pressing plate 102 coincides with the upper end of the rectangular frame 101, and then judge whether the substrate has abnormal convex deformation, thereby clearly displaying the deformation of the substrate, avoiding the situation where the deformed substrate raw material is used for circuit board processing due to unclear manual observation, thereby affecting the subsequent processing effect;

[0029] After the rectangular frame 101 finishes sliding, the sliding seat 601 can be operated to slide on the slide rail 302, so that the detection rod 602 gradually passes the upper side of the pressing plate 102. At this time, if the height of the pressing plate 102 is higher than the height of the rectangular frame 101 due to the deformation of the substrate, the detection rod 602 will automatically slide on the sliding seat 601 to overcome the elastic force of the second compression spring, that is, the deformation of the substrate can be automatically detected by monitoring the sliding of the detection rod 602, without the need for manual continuous naked eye observation next to the device, which further brings convenience to the actual use process;

[0030] A displacement sensor can be connected to the sliding seat 601 by bolts, and the sliding condition of the detection rod 602 can be detected by fixing the moving end of the displacement sensor to the detection rod 602. When the detection rod 602 slides, the displacement sensor can convert the displacement into an electrical signal for transmission, thereby completing the monitoring effect of the sliding condition of the detection rod 602.

[0031] The setting of the arc chamfer 106 facilitates the detection rod 602 to move smoothly to the upper side of the pressure plate 102, bringing convenience to subsequent detection work.

[0032] like Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 8-10 As shown:

[0033] It also includes a containing part 501 connected to the slide rail 302, a baffle 401 is slidably connected to the containing part 501, a transmission rod 402 is fixedly connected to the baffle 401, a push rod 603 is fixedly connected to the detection rod 602, a plurality of inclined plates 502 are fixedly connected in the containing part 501, and the plurality of inclined plates 502 are inclined plates with a lower front side and a higher rear side, a rectangular groove 104 is provided on the pressure plate 102, a third compression spring is fixedly connected between the containing part 501 and the baffle 401, each inclined plate 502 is loaded with paint of different colors, a through groove is provided on the front side of the containing part 501, and the through groove can be blocked by the baffle 401.

[0034] When the sliding seat 601 is operated to slide on the slide rail 302, the pushing rod 603 on the detection rod 602 will move synchronously with the detection rod 602. At this time, if the detection rod 602 has been pushed to a higher position by the pressure plate 102 that is higher than the rectangular frame 101, the pushing rod 603 will automatically push the transmission rod 402 to slide upward on the containing part 501 after moving to the contact position with the transmission rod 402, so that the baffle plate 401 slides upward, thereby clearing the position of the baffle plate 401 that was originally blocked in front of the containing part 501, thereby causing the paint in the containing part 501 to slide down, and then causing the paint to fall into the upper side of the substrate plate through the rectangular groove 104, thereby marking the substrate plate with deformation, further enabling subsequent staff to accurately find the deformed substrate plate, bringing convenience to actual operation;

[0035] When the deformation degree of the substrate plate is greater, the height of the upward protrusion of the pressure plate 102 on the rectangular frame 101 is higher, and the distance that the detection rod 602 slides upward is farther, that is, the height of the push rod 603 is positively correlated with the height of the pressure plate 102, and the higher the height of the push rod 603, the farther the push rod 603 can slide the transmission rod 402 upward, and the more inclined plates 502 exposed by the baffle 401, so that more pigment colors are added to the upper side of the substrate plate, so that subsequent staff can quickly and accurately judge the deformation condition and degree of deformation of the substrate plate according to the type of pigment color on the substrate plate, so as to quickly formulate subsequent repair or scrapping plans, further bringing convenience to actual use.

[0036] like Figure 3-6 As shown:

[0037] It also includes a fixing base 301 fixedly connected to the slide rail 302 , a container portion 501 is rotatably connected to the fixing base 301 , and a first motor capable of driving the container portion 501 to rotate is fixedly connected to the fixing base 301 .

[0038] When pigment powder needs to be added or the sliding seat 601 needs to be slid back and forth, the containing part 501 can be operated to rotate on the fixed seat 301, and then the containing part 501 can be rotated to the position where the through groove faces the upper side, so as to facilitate subsequent material addition or sliding reset operation of the sliding seat 601.

[0039] like Figure 1 As shown:

[0040] The rectangular groove 104 is provided with a circular chamfer 105 .

[0041] The setting of the arc chamfer 105 can guide the pigment, so that the fallen pigment can smoothly pass through the rectangular groove 104 and enter the upper side of the substrate plate, making it easy to use the pigment to complete the marking operation.

[0042] like Figure 2 As shown:

[0043] It also includes an L-shaped rod 202 fixedly connected to the bottom plate 201 , and a matching groove 107 is opened on the rectangular frame 101 .

[0044] The L-shaped rod 202 is provided so that when the substrate plate is placed, the substrate plate can be placed against the L-shaped rod 202, thereby facilitating the regular placement of the substrate plate on the bottom plate 201, and facilitating the subsequent comparison of the size of the substrate plate and the bottom plate 201;

[0045] The arrangement of the matching groove 107 enables the matching groove 107 to be inserted into the L-shaped rod 202 when the rectangular frame 101 is slid down, thereby providing sufficient space for the rectangular frame 101 to slide down.

[0046] like Figure 7-9 As shown:

[0047] It also includes a moving part 701 slidably connected to the rectangular frame 101 , a cylindrical rod 103 is fixedly connected to the pressing plate 102 , and a second electric push rod that can push the moving part 701 to slide is fixedly connected to the rectangular frame 101 .

[0048] After placing the substrate plate on the bottom plate 201, if it is found that the size of the substrate plate is larger than that of the bottom plate 201, the rectangular frame 101 can be lowered until the pressure plate 102 abuts against the upper side of the substrate plate, and then the movable part 701 is slid to press the movable part 701 on the upper side of the cylindrical rod 103 to fix the pressure plate 102 in this position, so that the pressure plate 102 and the bottom plate 201 cooperate to clamp and fix the substrate plate, and then the substrate plate can be cut using external cutting equipment so that the substrate plate can reach a size that completely fits and covers the upper side of the bottom plate 201, providing convenience for subsequent processing work.

[0049] like Figure 7 As shown:

[0050] The device also includes a striking head 702 fixedly connected to the moving part 701 .

[0051] In actual use, the movable part 701 can be slid regularly to make the knocking head 702 knock on the containing part 501, so as to prevent the paint from sticking inside the containing part 501 and facilitate the subsequent smooth sliding of the paint.

[0052] like Figure 4 As shown:

[0053] A transparent portion 503 is disposed at the rear side of the containing portion 501 .

[0054] The staff can accurately observe the content of the remaining pigment in the containing portion 501 through the transparent portion 503, so as to replenish the pigment in time, which provides convenience for subsequent marking work.

[0055] like Figure 2 As shown:

[0056] It also includes a positioning rod 203 fixedly connected to the L-shaped rod 202.

[0057] The positioning rod 203 can mark the appropriate thickness of the plate, so that the staff can judge whether the thickness of the plate meets the standard according to whether the plate reaches the height of the positioning rod 203, further expanding the inspection range of the equipment.

[0058] A circuit board processing technology, using the inspection equipment described above:

[0059] Step 1: Place the substrate plate on the bottom plate 201 and make the substrate plate rest against the L-shaped rod 202;

[0060] Step 2: slide the rectangular frame 101 downward until the rectangular frame 101 is slid to the lowest position within the sliding range;

[0061] Step 3: operate the sliding seat 601 to slide on the slide rail 302 until the detection rod 602 completely passes the lower side of the containing portion 501;

[0062] Step 4: operate the container 501 to rotate on the fixed seat 301, and then make the sliding seat 601 slide in the opposite direction to reset;

[0063] Step 5: If there is no pigment on the substrate plate and the detection rod 602 does not slide on the sliding seat 601, the substrate plate is removed, and subsequent plate making, drilling, hole plating and welding operations are performed to complete the circuit board processing effect;

[0064] Step 6: If there is pigment on the substrate board, the substrate board is determined to be repaired or scrapped according to the color type of the pigment.
