[0034] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0035] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. In addition, the terms "upper," "lower," "left," and "right" used in this utility model are only used with respect to the relative positions of the components of the utility model in the accompanying drawings.

[0036] Reference Figures 1 to 2 A detection and marking device includes a frame 1 and a detection frame 2 installed on the frame 1, a first drive device 3, a second drive device 4, a fixed bracket 5, a marking pen 6, a counterweight block 7 and a test probe module 8. The first drive device 3 is used to drive the detection frame 2 to rise and fall. A pressure plate 23 is provided at the bottom of the detection frame. The first drive device 3 is used to drive the pressure plate 23 to rise and fall. The test probe module 8 is installed below the marking pen 6. The test probe module 8 is used to detect the product 9 to be marked located above it. When the bottom of the detection frame 2 abuts against the product 9 to be marked, the test probe module 8 detects the performance, quality, etc. of the product 9 to be marked. After the detection is completed, the product 9 to be marked is marked according to the detection result. The product with qualified test results or unqualified products can be marked. The marking pen 6 can mark the product 9 to be marked when it moves downward. The test action of the test probe module 8 and the marking action of the marking pen 6 driven by the second drive device 4 can be controlled by a single-chip microcomputer. The counterweight 7 provides appropriate power for the marking pen 6 to fall, so that the marking is clearer and the pen tip is not easily blunted or damaged.

[0037] The first drive device 3 drives the inspection frame 2 downward to press the product to be marked 9 against the test probe module 8, thereby making the product to be marked 9 in close contact with the test probe module 8 below it, which is conducive to the test probe module 8 detecting the product to be marked 9. The test probe module 8 includes multiple detection probes. When the pressing plate 23 descends to press the product to be marked 9 against the test probe module 8, the pressing plate 23 can press each detection probe of the test probe module 8 against the product to be marked 9, and each detection probe detects the performance and quality of the product to be marked 9 located above it in close contact.

[0038] A mounting plate 11 for mounting the first drive device 3 is horizontally provided on the frame 1. A first fixing plate 51 is horizontally provided on the fixing bracket 5. The first fixing plate 51 is located above the mounting plate 11. The counterweight 7 is mounted on the upper end of the marking pen 6, with the tip 61 of the marking pen 6 protruding from the lower end of the marking pen 6. The cross-sectional dimensions of the counterweight 7 are larger than those of the marking pen 6. The first fixing plate 51 is provided with a first limiting hole 511 through which the marking pen 6 passes and is compatible with the marking pen 6. The mounting plate 11 is provided with a second limiting hole 111 through which the marking pen 6 passes and is compatible with the marking pen 6. The second limiting hole 111 vertically corresponds to the first limiting hole 511 and can have a cross-sectional dimension equal to that of the first limiting hole 511. The second drive device 4 is capable of driving the first fixing plate 51 to rise and fall. When the first fixing plate 51 descends, the marking pen 6 can fall. The provision of the first limiting hole 511 can ensure that the marking pen 6 is suspended on the fixing bracket 5 when not marking, and can also ensure that the marking pen 6 can pass through freely, so that the marking position is relatively stable.

[0039] The marking pen of this solution is installed on a fixed bracket 5 that can be raised and lowered, which is equivalent to a hanging setting. It is not directly fixed on the detection frame 2 or other parts. An appropriate counterweight is added to the marking pen 6. After the product test is completed, the cylinder is started to drive the first fixed plate 51 to descend. The marking pen can fall freely and the pen tip can mark a mark on the product. It can effectively prevent the pen tip from being damaged, extend the service life of the marking pen 6, and reduce production costs.

[0040] Specifically, a bottom plate 12 is provided at the bottom of the rack 2 , and the test probe module 8 is installed on the bottom plate 12 .

[0041] Specifically, two opposite limit blocks 121 are provided on the base plate 12, and the product 9 to be marked is located between the two limit blocks 121. The two limit blocks 121 are used to limit the movement of the product 9 to be marked between the two limit blocks 121, and the upper end surface of each limit block 121 is higher than the upper end surface of the test probe module 8.

[0042] Specifically, the second drive device 4 can be mounted on the mounting plate 11 of the frame 1 or fixedly mounted elsewhere on the frame 1. The detection frame 2 is further provided with a connecting plate 21 and a plurality of spaced-apart first connecting posts 22. The pressure plate 23 is vertically positioned between the connecting plate 21 and the base plate 12. The upper and lower ends of each first connecting post 22 are detachably fixedly connected to the connecting plate 21 and the pressure plate 23, respectively. The mounting plate 11 is positioned between the connecting plate 21 and the pressure plate 23, and each first connecting post 22 can slide through the mounting plate 11. The pressure plate 23 is provided with a through hole 231 for the marking pen 6 to pass through. The aperture or size of the through hole 231 can be larger than the size of the marking pen 6 to avoid interference with the marking pen 6 when it is lowered to mark a dot. The bottom end of the first drive device 3 is fixed to the mounting plate 11, and the upper end is connected to the connecting plate 21 and can drive the connecting plate 21 to rise and fall, thereby driving the pressure plate 23 to rise and fall.

[0043] Specifically, the fixing bracket 5 is further provided with a second fixing plate 52 and a plurality of second connecting columns 53 spaced apart from each other. The second fixing plate 52 is located below the first fixing plate 51.

The mounting plate 11 is located between the first fixing plate 51 and the second fixing plate 52, and each second connecting column 53 can slide through the mounting plate 11. The first fixing plate 51 and the second fixing plate 52 are both located between the connecting plate 21 and the pressing plate 23. The first limiting hole 511 and the third limiting hole 521 can ensure that the marking pen 6 remains in a vertical state, facilitating the free fall of the marking pen.

[0044] Specifically, the marking pen 6 is an oil-based pen with a durable ink tip. The Staedtler brand (model 318-F) is preferred. Its continuous use time is extended from 2 hours to 4 hours, and the total number of markings is increased from 5,000 to over 15,000, doubling the pen's continuous use time. Its service life is tripled, saving marking costs by over 20%.

[0045] Specifically, the first driving device 3 is a cylinder, and the second driving device 4 is a cylinder.

[0046] Specifically, the weight of the counterweight 7 is 30±5 g, so the pen tip is subjected to less impact force during marking and is not easily blunted, and the marking point is clearer and more stable.

[0047] An FPC testing device includes the detection marking device as described above, which is used to mark the FPC pads to be marked.
