[0029] The product stamping device of the embodiment of the present utility model will be specifically described below with reference to the drawings.

[0030] As Figures 1 - 5As shown in the figure, the product marking device according to an embodiment of the present invention includes: a driving component 1, a vision component 2, and a marking component 3. The vision component 2 is installed on the driving component 1 and is used for visually identifying defective products. The marking component 3 is installed on the driving component 1, and the driving component 1 drives the marking component 3 to move, driving the marking component 3 to act on the defective products to mark the defective products with defective product marks.

[0031] In other words, both the vision component 2 and the marking component 3 are installed on the driving component 1 and move under the drive of the driving component 1. Multiple workpieces are placed on the substrate. The vision component 2 can take pictures of the substrate and all workpieces, and identify good products, defective products, and the corresponding array position information through visual shooting. The marking component 3 mainly marks the defective products with defective product marks. The defective product marks are marks that are convenient for human eyes and machine vision to identify. Subsequent equipment can not operate on the defective products according to the defective product marks, thereby improving the operation efficiency, reducing the production cost, and avoiding waste of resources.

[0032] Further, the marking component 3 includes a marking member 3-10 and a clamping device. The marking member 3-10 is detachably installed on the clamping device, and the lower end of the marking member 3-10 can act on the defective products under the drive of the driving component 1.

[0033] In this embodiment, the marking member 3-10 is a marker pen. Of course, the marking member can also be other components, such as a laser marker, a spray valve, etc., which can leave defective product marks.

[0034] When the marking member 3-10 is a marker pen, when the ink of the marker pen is used up, the marker pen needs to be replaced. The marker pen is detachably installed on the clamping device, which is convenient for disassembling and assembling the marker pen.

[0035] Specifically, the clamping device includes a clamping part and a mounting part. The clamping part is connected to the marking member 3-10, the mounting part is connected to the driving component 1, the clamping part is slidably connected to the mounting part, and a spring 3-6 is arranged between the clamping part and the mounting part. The spring 3-6 is used to apply pressure to the marking member 3-10 during marking.

[0036] That is to say, the mounting part is mainly connected to the driving component 1, and the clamping part is mainly used to clamp the marker pen. The clamping part and the mounting part are set to be slidably connected, and the spring 3-6 is arranged. When the marking component 3 approaches the product, the marker pen contacts the defective product, and at the same time, the spring 3-6 is compressed, thereby applying a certain force to the marker pen to ensure that the marker pen can leave a mark on the surface of the defective product during the marking process. At the same time, the spring 3-6 can also generate buffering to avoid hard contact with the product.

[0037] Among them, the installation part includes: a first installation block 3-1, a second installation block 3-2, a pressing plate 3-3 and a third installation block 3-4. The first installation block 3-1 has a clamping protrusion. The pressing plate 3-3 is installed on the first installation block 3-1. An installation groove is formed between the clamping protrusion and the pressing plate 3-3. The second installation block 3-2 is arranged in the installation groove, and the third installation block 3-4 is connected to the second installation block 3-2.

[0038] In this embodiment, the installation groove formed between the clamping protrusion and the pressing plate 3-3 is a dovetail groove. At the same time, the second installation block 3-2 is matched with the dovetail groove, and the second installation block 3-2 can slide along the length direction of the dovetail groove. The pressing plate 3-3 is fixed on the first installation block 3-1 by screws. Only need to loosen the screws to make the pressing plate 3-3 loose from the clamping protrusion on the first installation block 3-1. In this way, the second installation block 3-2 can be adjusted to a suitable position for installation as needed.

[0039] Among them, the clamping part includes: a first clamping block 3-7 and a second clamping block 3-8. The first clamping block 3-7 is slidably connected to the third installation block 3-4 through a linear guide 3-11. The second clamping block 3-8 is installed on the first clamping block 3-7. The marking part 3-10 is clamped between the first clamping block 3-7 and the second clamping block 3-8.

[0040] In other words, a marker pen is clamped between the first clamping block 3-7 and the second clamping block 3-8. In order to ensure firm clamping, arc grooves matched with the marker pen are provided on both the first clamping block 3-7 and the second clamping block 3-8. The first clamping block 3-7 and the second clamping block 3-8 are fixed together by two screws, and the two screws are respectively located on the left and right sides of the marker pen.

[0041] Preferably, a limit adjustment block 3-9 is further installed on the first clamping block 3-7. The limit adjustment block 3-9 has a matching part, and the matching part is matched with the step surface on the marking part 3-10 to position the marking part 3-10.

[0042] That is to say, the limit adjustment block 3-9 is L-shaped. The side plate of the limit adjustment block 3-9 is fixed to the side surface of the first clamping block 3-7. The upper surface of the bottom plate of the limit adjustment block 3-9 abuts against the step surface on the marker pen, so as to complete the installation and positioning of the marker pen. A waist-shaped hole is provided on the side plate of the limit adjustment block 3-9, and the screw passes through the waist-shaped hole and is connected to the first clamping block 3-7. The provision of the waist-shaped hole can adjust the installation position between the limit adjustment block 3-9 and the first clamping block 3-7 in the height direction.

[0043] More preferably, a pressure adjustment column 3-5 is installed on the third mounting block 3-4. The pressure adjustment column 3-5 is located above the first clamping block 3-7, and the spring 3-6 is located between the pressure adjustment column 3-5 and the first clamping block 3-7. The pressure adjustment column 3-5 can adjust its position along the sliding direction of the first clamping block 3-7 to change the pressure exerted by the spring 3-6.

[0044] That is, during the marking process, after the marker pen touches the defective product, the spring 3-6 is compressed, thereby applying pressure to the marker pen to ensure that the marker pen can make a defective product mark on the defective product. If the pressure is too small, the defective product mark cannot be made. Therefore, the pressure adjustment column 3-5 is provided. There is a round hole for installing the pressure adjustment column 3-5 on the third mounting block 3-4. The pressure adjustment column 3-5 is pressed in the round hole on the third mounting block 3-4 by screws. Loosening the screws can adjust the installation position of the pressure adjustment column 3-5 in the height direction, so that the pressure of the spring 3-6 can be adjusted as needed.

[0045] According to an embodiment of the present invention, the driving assembly 1 includes a mounting base plate 1-1, a Z-axis module 1-2, and a Z-axis hanging plate 1-3. The Z-axis module 1-2 is provided on the mounting base plate 1-1, and the Z-axis hanging plate 1-3 is provided at the output end of the Z-axis module 1-2. The vision assembly 2 and the marking assembly 3 are both installed on the Z-axis hanging plate 1-3, and the Z-axis module 1-2 drives the Z-axis hanging plate 1-3 to move in the Z direction.

[0046] Of course, the driving assembly 1 may further include a gantry motion mechanism. The gantry motion mechanism drives the mounting base plate 1-1 to move in the XY plane to facilitate photographing all products, while the Z-axis module 1-2 performs Z-direction movement to approach the defective product for marking operation.

[0047] According to an embodiment of the present invention, the vision assembly 2 includes a camera 2-1, a lens 2-2, and a light source 2-5. The camera 2-1 is fixed to the Z-axis hanging plate 1-3 through a camera mounting block 2-3. The lens 2-2 is installed on the camera 2-1. The light source 2-5 is installed on the Z-axis hanging plate 1-3 through a light source mounting block 2-4. The lens 2-2 is located between the camera 2-1 and the light source 2-5.

[0048] The specific steps of the present invention during operation are as follows: Step 1: The vision assembly 2 scans the QR code on the substrate to obtain the Mapping information of all products on the substrate; Step 2: Scan the Mark point on the substrate to position the substrate; Step 3: Scan all products one by one and measure the height of the defective products among them; Step 4: The marking assembly 3 marks the defective products with defective product marks; Step 5: The vision assembly 2 photographs all products and performs visual inspection on the marking results; Step 6: Update the Mapping information according to the marking results.

[0049] That is to say, the relevant information of all products on the substrate can be obtained from the QR code on the substrate. Then, after positioning the substrate, all products are identified, and the height of defective products is measured to facilitate subsequent marking of defective products. After marking, visual inspection is carried out. If there is a missed marking situation, the missed defective products need to be marked again. If there is a mis-marking situation, the Mapping information needs to be updated, changing the original non-defective products to defective products.

[0050] Among them, the Mapping information in step one includes the array information of all products on the substrate and the non-defective or defective product information corresponding to all products. For example, if non-defective products are recorded as 0 and defective products are recorded as 1, then they are marked according to the actual position array of the products. If there are two rows of products, with 5 products in each row, the first row is 00100 and the second row is 01001. Then, the third product from left to right in the first row is a defective product, and the rest are non-defective products. In the second row, the second and fifth products from left to right are defective products, and the rest are non-defective products. In this way, during the marking operation, it is not necessary to identify the three-dimensional coordinates of each product. Only the defective products need to be identified through the array, with a relatively small amount of data and easy implementation.

[0051] Among them, in step four, the way to mark defective products with defective product marks is to draw defective product marks with a pen or use laser marking or spray glue marking. Of course, the marking methods are not limited to the above several, as long as defective product marks can be made on defective products.

[0052] All in all, the structure of the present utility model is simple and compact. By installing the vision component 2 and the marking component 3 on the driving component 1, it is convenient for the driving component 1 to drive the vision component 2 and the marking component 3 to move simultaneously. The vision component 2 can take pictures of products and quickly identify defective products through machine vision. The marking component 3 can make defective product marks on defective products, so that unconnected devices can quickly identify defective products through the defective product marks. The marking process of the present utility model is simple. First, the vision component 2 scans to obtain the positions of all products in the array and the corresponding non-defective or defective product information, then scans each product one by one and measures the height of defective products to facilitate the marking component 3 to make defective product marks on defective products. Finally, the Mapping information of all products is updated by detecting whether there is a missed marking or mis-marking. The marking steps are simple, and the defective products in the products can be quickly marked and the product status can be updated, so as to facilitate subsequent devices to quickly identify products.
