DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0032] Example 1

[0033] This embodiment 1 provides a base plate and DBC identifier identification device for IGBT, such as Figure 1 and Figure 2 As shown, including:

[0034] A base 1, wherein a placement area 11 for placing a product to be identified is provided on the top of the base 1;

[0035] A support frame 2, wherein the support frame 2 is disposed on the base 1, and a code reading component 3 is disposed on the support frame 2 and is located directly above the placement area 11;

[0036] The positioning and adjusting component 4 is arranged outside the placement area 11 and is used for positioning products to be identified of different sizes.

[0037] In the prior art, the DBC substrate on the product to be identified may be provided with multiple DBC identification codes or there may be multiple QR codes on the bottom plate. The product cannot adapt to the fixed positioning device, which may cause inaccurate positioning and lead to a series of problems such as incomplete subsequent code reading information.

[0038] In order to solve the above problem, the present embodiment provides a positioning adjustment component 4, which is flexibly moved according to the size of the product to be identified, thereby ensuring that the product to be identified placed on the base 1 is always located directly below the code reading component 3 to read the QR code on the base plate and the DBC code on the DBC substrate.

[0039] The specific working process of this embodiment is as follows:

[0040] The product to be identified with the DBC code and the QR code is placed in the placement area 11 on the base 1. The product to be identified is aligned with the positioning adjustment component 4. At this time, the product to be identified is located directly below the code reading component 3. The code reading component 3 photographs and reads the QR code on the bottom plate and the DBC code on the DBC substrate to obtain the data therein.

[0041] Furthermore, the positioning adjustment component 4 includes a first positioning block 41 and a second positioning block 42 , and the first positioning block 41 and the second positioning block 42 are respectively moved or fixed along the length and width directions of the product to be identified by fixing parts.

[0042] like Figure 1 As shown, in order to adapt to the size of the product to be identified, the first positioning block 41 moves to the left and the second positioning block 42 moves backward; thus, the center of the products to be identified of different sizes remains unchanged, and the code reading component 3 can completely read the DBC identification code on the product to be identified.

[0043] Among them, the first positioning block 41 and the second positioning block 42 are both provided with a first positioning hole 43, and the base 1 is provided with a plurality of second positioning holes 44 for cooperating with the first positioning hole 43 along the length and width directions of the product to be identified, and the fixing part includes a bolt passing through the first positioning hole 43 and being threadedly connected to one of the second positioning holes 44.

[0044] Specifically, the plurality of second positioning holes 44 are evenly arranged, such as Figure 2 and Figure 3 As shown, in order to ensure the stable connection between the first positioning block 41 and the second positioning block 42 and the base 1, two first positioning holes 43 can be set in the first positioning block 41 and the second positioning block 42, and two rows of neat second positioning holes 44 can be set on the base 1 and fixed by bolts after matching with the corresponding two first positioning holes 43. Finally, the positions of the first positioning block 41 and the second positioning block 42 are adjusted to adapt to products to be identified of different sizes.

[0045] Furthermore, in order to facilitate the placement and taking of the product to be identified on the top of the base 1, it is configured as follows: the base 1 is provided with spaced grooves 8 located on both sides of the placement groove.

[0046] Specifically, in this embodiment, the distance between the two spaced grooves 8 is greater than the size of the product, so that there is a certain gap between the left and right sides of the product and the corresponding spaced grooves 8. When taking or placing, the staff can enter the gap between the two sides of the product and the corresponding spaced grooves 8, so as to facilitate the safe taking out or placing of the product.

[0047] Furthermore, in order to ensure the stable placement of the base 1 , it is configured as follows: support feet 9 are provided at the four corners of the bottom of the base 1 .

[0048] like Figure 2 and Figure 4 As shown, the utility model also proposes another embodiment, the code reading component 3 includes a support plate 31, a code recognition camera 32 is connected to the bottom of the support plate 31, and the code recognition camera 32 is located directly above the placement slot; the support plate 31 is connected to the support frame 2 through a lifting component 33.

[0049] In this embodiment, the support plate 31 is used to stably support the barcode recognition camera 32, and the lifting assembly 33 is used to adjust the height of the support plate 31 to flexibly adjust the working height of the barcode recognition camera 32 to ensure that the focus of the barcode recognition camera 32 is clear and the subsequent barcode reading work is carried out normally.

[0050] Wherein, the lifting assembly 33 comprises:

[0051] The screw rod 331 is vertically rotatably arranged on the support frame 2 and is threadably connected to the support plate 31;

[0052] The limiting rod 332 is vertically arranged on the support frame 2 and is slidably connected to the support plate 31 .

[0053] In order to ensure the normal rotation of the screw rod 331 , it is configured as follows: one end of the screw rod 331 is connected to a rotating handle 333 .

[0054] Specifically, the working process of the lifting assembly 33 of this embodiment is as follows:

[0055] The rotating handle 333 drives the screw rod 331 to rotate. The screw rod 331 is threadedly connected to the support plate 31 and does not rotate with the screw rod 331 under the limit of the limit rod 332. Therefore, the support plate 31 moves upward to drive the barcode recognition camera 32 to move upward, and finally increases the working height of the barcode recognition camera 32.

[0056] On the contrary, the rotating handle 333 drives the screw rod 331 to rotate in the opposite direction. The screw rod 331 is threadedly connected to the support plate 31 and does not rotate with the screw rod 331 under the limit of the limit rod 332. Therefore, the support plate 31 moves downward, driving the barcode recognition camera 32 to move downward, and finally lowering the working height of the barcode recognition camera 32.

[0057] Furthermore, in order to automatically trigger the operation of the code recognition camera 32 , it is configured as follows: a placement slot is provided on the base 1 in the placement area 11 , a sensing module 7 is provided in the placement slot, and the sensing module 7 is communicatively connected with the code recognition camera 32 .

[0058] In this embodiment, a sensing module 7 is arranged in the placement slot, and the product to be identified is located directly above the sensing module 7;

[0059] Specifically, the sensing module 7 includes a sensor and a controller, wherein the main function of the sensor is to trigger the operation of the barcode recognition camera 32 when the presence of the product is sensed; that is, when the sensor senses that the product is in the placement area 11, the controller controls the barcode recognition camera 32 to operate and collect information. The sensor in this embodiment is not limited to a photoelectric sensor, an infrared sensor, etc., so the controller and the sensor are existing electronic devices and are not described in detail here.

[0060] like Figure 4 As shown, the utility model also proposes another embodiment, in order to ensure the code recognition environment of the code recognition camera 32, it is configured as follows: a light source assembly 5 located below the code recognition camera 32 is arranged on the top of the base 1, and the light source assembly 5 includes a fixing frame 51 and a combined light source 52, and the combined light source 52 is installed at the bottom of the fixing frame 51 through a sheet metal part 53; an identification port 511 cooperating with the code recognition camera 32 is opened in the middle of the fixing frame 51.

[0061] In this embodiment, the combined light source 52 includes illuminating the product on the base 1 to ensure that the code recognition camera 32 clearly captures the DBC identification code information on the product.

[0062] like Figure 1As shown, in order to avoid accidental collision by the staff and glare from the light source, it is configured as follows: a protective shell 6 located outside the code recognition camera 32 and the combined light source 52 is installed on the support frame 2.

[0063] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
