[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0033] According to an embodiment of this utility model, a weighing and barcode scanning device is provided for weighing and scanning products before packaging. It is understood that the products to be tested in this utility model include, but are not limited to, electronic products such as battery cells, mechanical products such as automotive parts, or daily necessities such as fresh food and express parcels.

[0034] Specifically, such as Figure 1 As shown, the weighing and scanning device includes a controller (not shown), a frame 1, and a weighing mechanism 2 and an image acquisition mechanism 3 mounted on the frame 1. The controller is electrically connected to the weighing mechanism 2 and the image acquisition mechanism 3. The weighing mechanism 2 has a weighing platform for stacking at least one layer of products to be tested, and multiple products to be tested can be placed on each layer. The image acquisition mechanism 3 is located above the weighing platform and is used to acquire image information of each layer of products to be tested on the weighing platform.

[0035] The weighing mechanism 2 is configured to generate a first signal when the weight of each layer of products to be tested reaches a first preset weight, and transmit the first signal to the controller. The controller is configured to, upon receiving the first signal, control the image acquisition mechanism 3 to acquire image information of each layer of products to be tested on the weighing mechanism 2; and the controller is configured to identify the coding information of each product to be tested based on the image information of each layer of products to be tested.

[0036] It should be noted that the first preset weight can be the total weight of the current layer of products under test when each layer is fully loaded; or, in some cases, each layer of products under test needs to be placed on a product tray (not shown in the figure), and the first preset weight can be the total weight of the current layer of products under test and the product tray when each layer is fully loaded. Alternatively, the first signal can be understood as a full-tray signal, i.e., the signal when each layer is fully loaded. At this time, the image acquisition mechanism 3 can acquire image information of one layer of products under test, and the controller can complete the identification of the encoded information of one layer of products under test at once based on the image information.

[0037] Understandably, due to factors such as processing errors, the weight of a single product to be tested may vary. Therefore, the first preset weight can be a weight range, as long as the weight detected by the weighing mechanism 2 when each layer is full is within that range. This utility model does not limit the specific value or range of the first preset weight, and it can be adaptively adjusted according to the weight of the product to be tested and the number of products to be tested in each layer in the packaging standard.

[0038] The specific scanning process is as follows: when the product to be tested on each layer reaches the first preset weight, the weighing mechanism 2 transmits the first signal to the controller; the controller controls the image acquisition mechanism 3 to acquire the image information of the product to be tested on the current layer on the weighing mechanism 2, and the controller completes the identification of the coding information of each product to be tested in the image based on the acquired image information. With this setup, the controller can complete the identification of the coding information of multiple products to be tested at once based on the image information, without needing to scan them one by one, resulting in high scanning efficiency. In this embodiment, the weighing mechanism 2 and the image acquisition mechanism 3 are integrated into a single design and work in conjunction with the controller. In practical applications, the products to be tested are stacked layer by layer on the weighing mechanism 2, and the coding information of the products to be tested is identified simultaneously with the weighing, simplifying the scanning and weighing operation process and improving the efficiency of the scanning and weighing process.

[0039] Furthermore, in some embodiments, the weighing and scanning device further includes an audible and visual signal generator, which is electrically connected to the controller. The weighing mechanism 2 is configured to generate a second signal when the total weight of the product to be measured reaches a second preset weight, and transmit the second signal to the controller. The controller is configured to control the audible and visual signal generator to emit an audible and visual signal upon receiving the second signal. It should be noted that the second preset weight specifically refers to the total weight required by the packaging standard; it can be understood that the second preset weight can also be a numerical range.

[0040] In this embodiment, the specific weighing and scanning process is as follows: the products to be tested are stacked layer by layer, and the coding information of each layer of products to be tested is identified; when the weighing mechanism 2 detects that the products to be tested have reached the second preset weight, the second signal is transmitted to the controller; the controller controls the audible and visual signal device to issue an alarm. In this embodiment, the alarm is issued in a timely manner through weight monitoring, thereby removing the entire stack of products to be tested and packing them into boxes, without the need for manual monitoring, which facilitates automated operation.

[0041] Furthermore, such as Figure 1 As shown, the frame 1 has a height direction Z, and a first direction X and a second direction Y intersecting the height direction. In some cases, the height direction Z, the first direction X, and the second direction Y can be perpendicular to each other.

[0042] In some embodiments, the frame 1 includes a worktable 11 with an upward-opening mounting cavity 110. At least a portion of the structure of the weighing mechanism 2 is embedded in the mounting cavity 110, which reduces the height of the weighing platform, thereby reducing the operating height and difficulty.

[0043] For example, such as Figure 1 As shown, the frame 1 includes a frame body and the aforementioned worktable 11. The worktable 11 may include a first support plate 111 and a second support plate 112 spaced apart along the height direction Z of the frame 1. Both the first support plate 111 and the second support plate 112 are fixedly mounted on the frame body, with the first support plate 111 positioned above the second support plate 112. The first support plate 111 and the second support plate 112 together form the aforementioned mounting cavity 110. Specifically, the first support plate 111 has a mounting hole extending through the frame 1 along the height direction Z. This mounting hole, together with the space between the first support plate 111 and the second support plate 112, forms the mounting cavity 110. The bottom of the weighing mechanism 2 can be placed on or connected to the second support plate 112, ensuring stability and reliability.

[0044] For example, the workbench 11 may also include only the first support plate 111, on which an upward-opening groove is provided, forming the aforementioned mounting cavity 110.

[0045] The weighing platform can be located above the workbench 11, flush with the upper surface of the workbench 11, or below the upper surface of the workbench 11. Preferably, the weighing platform is located above the workbench 11 to facilitate the placement of the product to be tested.

[0046] Furthermore, the weighing mechanism 2 includes a weighing pan 21 and a weighing body 22. At least a portion of the structure of the weighing body 22 is housed within the aforementioned mounting cavity 110, and the weighing pan 21 is placed on top of the weighing body 22. Specifically, the weighing body 22 includes a base and a sensing end for weighing. The sensing end is located on top of the weighing body 22, the base is placed on or connected to the second support plate 112, and the weighing pan 21 is placed on the sensing end. Understandably, the upper surface of the weighing pan 21 forms a weighing platform.

[0047] In some embodiments, the weighing mechanism 2 further includes a positioning element 23, which is disposed on the weighing platform and used to position the product to be tested or the product pallet. For example, Figure 4As shown, the positioning component 23 includes intersecting first and second stop portions 231 and 232, respectively, which are adjustably connected to the weighing pan 21. In this embodiment, the intersecting first and second stop portions 231 and 232 can position adjacent sides of a product or product tray to define the initial stacking position of the product or product tray, facilitating standardized production operations. By adjusting the position of the first or second stop portion 231, or simultaneously adjusting the first and second stop portions 231 and 232 on the weighing pan 21, different specifications of products or product trays can be matched, enabling standardized weighing and scanning operations for various products and improving applicability.

[0048] It should be noted that the included angle between the first retaining edge 231 and the second retaining edge 232 depends on the structural shape of the product under test or the product tray, and can be any angle between 0 and 180°, as long as it can match the adjacent sides of the product under test or the product tray and achieve a positioning function. In some cases, the first retaining edge 231 and the second retaining edge 232 can be perpendicular to each other, that is, the included angle between them is 90°.

[0049] Taking the battery cell as an example, the battery cells often need to be stacked on a battery cell tray (i.e., the product tray mentioned above). Depending on the battery cell model and packaging standards, the battery cell tray has multiple slots for placing the cells, and the battery cell tray is typically rectangular. In this case, the first retaining edge 231 and the second retaining edge 232 can be perpendicular to each other. During use, the battery cell tray is placed on the weighing pan 21. The first retaining edge 231 and the second retaining edge 232 can respectively define the positions of adjacent sides of the battery cell tray, thereby accurately positioning the battery cell tray on the weighing pan 21.

[0050] Furthermore, the first retaining edge 231 and the second retaining edge 232 can be separate components, connected as a single unit, or integrally formed. When the first retaining edge 231 and the second retaining edge 232 are separate components, they can be respectively and adjustably connected to the weighing pan 21, or one of them can be adjustably connected to the weighing pan 21. When the first retaining edge 231 and the second retaining edge 232 are integral components or integrally formed, both are adjustably connected to the weighing pan 21.

[0051] For example, the first retaining edge portion 231 and the second retaining edge portion 232 are integrally formed. Figure 4As shown, the first retaining edge 231 extends along the first direction X, and the second retaining edge 232 extends along the second direction Y. The first direction X and the second direction Y intersect; in some cases, the first direction X and the second direction Y are perpendicular, and both the first direction X and the second direction Y are perpendicular to the height direction Z. In the height direction Z, the weighing pan 21 has a rectangular cross-sectional shape. The first retaining edge 231 and the second retaining edge 232 are connected at one of the corners of the weighing pan 21.

[0052] Specifically, the weighing pan 21 can be provided with multiple sets of weighing pan connection holes 211, and the positioning member 23 is provided with at least one corresponding flange connection hole 233. The positioning member 23 can be fixed to the weighing pan 21 using fasteners such as bolts through one set of weighing pan connection holes 211 and the flange connection hole 233. Figure 4 As shown, multiple sets of the aforementioned weighing pan connection holes 211 are arranged sequentially at intervals along the diagonal direction of the weighing pan 21, i.e., the R direction. When the positioning member 23 is connected to different sets of weighing pan connection holes 211, the relative position of the positioning member 23 and the weighing pan 21 can be adjusted, so that the first stop edge 231 and the second stop edge 232 are adjustablely connected to the weighing pan 21.

[0053] Each set of weighing pan connection holes 211 may include at least one weighing pan connection hole 211, or may include multiple holes, as long as they can fulfill the function of fixing the first stop edge 231 and the second stop edge 232. For example... Figure 4 In the illustrated embodiment, each set of weighing pan connection holes 211 includes three weighing pan connection holes 211, that is... Figure 4 The three weighing pan connection holes 211 are connected by a dashed line and are located at the three vertices of a triangle. Correspondingly, a retaining edge connection hole 233 is provided at the first retaining edge 231, the second retaining edge 232, and the connection between the two. The three retaining edge connection holes 233 are respectively provided with the three weighing pan connection holes 211. In this way, there are three connection points in a triangle between the positioning member 23 and the weighing pan 21, which provides good connection stability, prevents rotation or displacement, and ensures the positioning effect.

[0054] Furthermore, in some embodiments, such as Figure 5 As shown, the weighing mechanism 2 also includes a limiting frame 24, which is connected to the lower surface of the weighing pan 21 and surrounds the outside of the sensing end of the weighing body 22. When the weighing pan 21 is placed on the sensing end of the weighing body 22, the limiting frame 24 can limit the weighing pan 21 to ensure that the image acquisition mechanism 3 can be opposite to the upper surface of the weighing pan 21, thus ensuring the image acquisition effect. Understandably, the shape of the limiting frame 24 depends on the shape of the sensing end. For example, if the cross-sectional shape of the sensing end in the height direction Z is rectangular, then the limiting frame 24 can be a rectangular frame structure.

[0055] For example, the limiting frame 24 can be welded or bonded to the lower surface of the weighing pan 21, or fixed to the lower surface of the weighing pan 21 by rivets, screws or the like.

[0056] Furthermore, in some embodiments, the weighing and scanning device also includes an adjustment mechanism 4, which is connected between the image acquisition mechanism 3 and the frame 1. The adjustment mechanism 4 is used to adjust at least the position of the image acquisition mechanism 3 in the height direction Z. In this embodiment, by adjusting the position of the image acquisition mechanism 3 in the height direction Z, the image acquisition requirements of products of different specifications can be met, facilitating the replacement of products under test and further improving applicability.

[0057] Furthermore, the image acquisition mechanism 3 may include a camera 31 and at least one first light source 32, both of which are connected to the adjustment mechanism 4. The camera 31 may be located above or at the same height as the first light source 32, preferably above it. In this embodiment, the camera 31 cooperates with the controller to facilitate image acquisition, and the first light source 32 provides backlighting for the camera 31 to ensure effective image capture.

[0058] In some embodiments, the adjustment mechanism 4 can be a linear motor module or a ball screw module, etc., which is connected to both the camera 31 and the first light source 32, controlling the camera 31 and the first light source 32 to move synchronously in the height direction Z or other directions. For example, the adjustment mechanism 4 is a linear motor module, which includes a first linear motor and a second linear motor slidably connected. The first linear motor is connected to the camera 31 and the first light source 32 to drive the camera 31 and the first light source 32 to move linearly along the height direction Z; the second linear motor is connected to the first linear motor to drive the camera 31 and the first light source 32 to move linearly along the first direction X or the second direction Y.

[0059] In some embodiments, the adjustment mechanism 4 may include two position adjustment mechanisms, which are respectively connected to the camera 31 and the first light source 32, thereby controlling the camera 31 and the first light source 32 to move in the height direction Z or other directions, thus providing greater flexibility.

[0060] like Figures 1-3In the illustrated embodiment, the frame 1 includes a first support frame 12 and a second support frame 13 arranged sequentially along the height direction Z on the frame body, with the first support frame 12 located above the second support frame 13. The adjustment mechanism 4 includes a first position adjustment mechanism and a second position adjustment mechanism. The first position adjustment mechanism is connected between the first support frame 12 and the camera 31, and is used to adjust the position of the camera 31 in the height direction Z; the second position adjustment mechanism is connected between the second support frame 13 and the first light source 32, and is used to adjust the position of the first light source 32 in the height direction Z.

[0061] Furthermore, in some embodiments, such as Figure 2 As shown, the first position adjustment mechanism includes a first guide 41, a sliding connector 42, and a first locking member (not shown in the figure).

[0062] The first guide member 41 can be fixedly connected to the frame 1, or it can be adjustablely connected to the frame 1 along the first direction X position. Specifically, the first guide member 41 is fixedly connected to the second support frame 13 or adjustablely connected along the first direction X position.

[0063] by Figure 2 As shown in the example, the first guide member 41 is adjustablely connected to the frame 1 along the first direction X. The first direction X can be the length direction of the weighing and scanning device, and the first direction X intersects with the height direction Z, preferably perpendicular to it. The sliding connector 42 is connected to the camera 31 and is slidably connected to the first guide member 41 along the height direction Z. The first locking member is detachably connected between the first guide member 41 and the sliding connector 42 to allow or restrict the relative sliding of the first guide member 41 and the sliding connector 42. In this embodiment, the first position adjustment mechanism can adjust the position of the camera 31 in both the first direction X and the height direction Z, which can ensure the alignment effect between the camera 31 and the product under test, as well as ensure the shooting effect of products under test with different specifications.

[0064] For example, the first guide member 41 may include a support portion 411 and a first sliding rod portion 412. The support portion 411 can be slidably connected to the first support frame 12, and the two can be locked by fasteners such as bolts. The first sliding rod portion 412 extends along the height direction Z. One end of the first sliding rod portion 412 along the height direction Z is connected to the support portion 411, and the other end can be slidably connected to the sliding connector 42, or threadedly connected, etc., as long as the position of the sliding connector 42 in the height direction Z can be adjusted.

[0065] For example, the support portion 411 is provided with a plurality of support portion connecting holes spaced at intervals along the height direction Z, and the sliding connector 42 is provided with corresponding sliding connector connecting holes. The first locking member is detachably connected to the support portion connecting holes and the sliding connector connecting holes. When the first locking member is detached from or released from the support portion connecting holes and the sliding connector connecting holes, relative sliding between the first guide member 41 and the sliding connector 42 is allowed; the first locking member is securely connected to the support portion connecting holes and the sliding connector connecting holes, restricting relative sliding between the first guide member 41 and the sliding connector 42. For example, the first locking member can be a bolt, cotter pin, buckle, etc.

[0066] Furthermore, in some embodiments, such as Figure 3 As shown, the second position adjustment mechanism includes a second guide member 43, a support member 44, and a second locking member 45.

[0067] The second guide member 43 can be fixedly connected to the frame 1, or it can be adjustablely connected to the frame 1 along the first direction X position. Specifically, the second guide member 43 is fixedly connected to the third support frame 14 or adjustablely connected along the first direction X position.

[0068] by Figure 3 As shown in the example, the second guide member 43 is adjustablely connected to the frame 1 along the first direction X. The support member 44 is connected to the first light source 32 and slidably connected to the second guide member 43 along the height direction Z. The second locking member 45 is detachably connected between the second guide member 43 and the support member 44 to allow or restrict the relative sliding of the second guide member 43 and the support member 44. In this embodiment, the second position adjustment mechanism can adjust the position of the first light source 32 in both the first direction X and the height direction Z to adapt to products of different specifications and ensure the lighting effect.

[0069] The support member 44 can be a rod-shaped structure extending along the second direction Y, which can be the depth direction of the weighing and scanning device. The second direction Y intersects with the first direction X and the height direction Z, and preferably all three are perpendicular. Two of each of the aforementioned second guide member 43 and second locking member 45 are provided. The two ends of the support member 44 along the second direction Y are respectively connected to the second support frame 13 using a second guide member 43 and a second locking member 45.

[0070] For example, at least two sets of the second position adjustment mechanism and the first light source 32 can be provided. At least two sets of the second position adjustment mechanism are arranged at intervals along the second direction Y on the second support frame 13, and at least two sets of the first light source 32 are respectively installed on the support member 44 of the at least two sets of the second position adjustment mechanism.

[0071] For example, the second guide member 43 may include a connecting portion 431 and a second sliding rod portion 432. The connecting portion 431 can be slidably connected to the second support frame 13 and the two can be locked by fasteners such as bolts. The second sliding rod portion 432 extends along the height direction Z. One end of the second sliding rod portion 432 along the height direction Z is connected to the connecting portion 431, and the other end is connected to the support member 44 through a second locking member 45.

[0072] For example, the second locking member 45 includes a locking block and two locking members, the first end of the locking block along the first direction X is used to connect with the support member 44, and the second end is used to connect with the second sliding rod portion 432.

[0073] Specifically, the first end of the locking block includes a first half 451 and a second half 452 connected together. The first half 451 and the second half 452 together form a first mounting hole extending along the second direction Y, and a first gap communicating with the first mounting hole. The end of the support member 44 passes through the first mounting hole, and the first gap extends between one end face of the locking block along the first direction X and two end faces along the second direction Y. One of the two locking members passes through the first half 451, the second half 452, and the first gap to fix the locking block and the support member 44 when tightened, and to allow the locking block and the support member 44 to move relative to each other when loosened.

[0074] Specifically, the second end of the locking block includes a third half 453 and a fourth half 454 connected together. The third half 453 and the fourth half 454 together form a second mounting hole extending through in the height direction Z, and a second gap communicating with the second mounting hole. The end of the second sliding rod portion 432 passes through the second mounting hole, and the second gap extends between the other end face of the locking block in the first direction X and the two end faces in the height direction Z. The other locking member of the two locking members passes through the third half 453, the fourth half 454 and the second gap to fix the locking block and the second sliding rod portion 432 when tightened, and to allow the locking block and the second sliding rod portion 432 to move relative to each other when loosened.

[0075] For example, the locking block can be a block structure, and the locking element can be a bolt.

[0076] Furthermore, in some embodiments, such as Figure 1 As shown, the frame 1 includes a third support frame 14 mounted on the frame body, which can be positioned above the first support frame 12 and the second support frame 13. The weighing and scanning device also includes a second light source 5, which is connected to the frame 1, specifically to the third support frame 14. The second light source 5 is located above the weighing platform and the image acquisition mechanism 3, providing an operating light source for the scanning and weighing process.

[0077] The following describes the specific operation process of the weighing and scanning device of this utility model, taking the product to be tested as a battery cell as an example:

[0078] 1. Place the battery cell tray on the weighing platform;

[0079] 2. Place the battery cells into the battery cell tray until the battery cell tray is full. When the weighing mechanism 2 detects that the weight has reached the first preset weight, the weighing mechanism 2 generates a full tray signal (i.e., the first signal) and transmits it to the controller.

[0080] 3. After receiving the full-disk signal, the controller controls the image acquisition mechanism 3 to illuminate and photograph the entire disk of cells;

[0081] 4. Repeat steps 1-3 until the weighing mechanism 2 detects that the weight has reached the second preset weight. At this time, the total weight of the battery cells on the battery cell tray meets the packing requirements. The weighing mechanism 2 generates a second signal and transmits it to the controller.

[0082] 5. After receiving the second signal, the controller controls the sound and light signal generator to emit sound and light signals;

[0083] 6. Based on the sound and light signals, the operator or robotic arm removes the entire stack of battery cells, completing the packing process.

[0084] According to an embodiment of this utility model, another aspect provides a packaging system, including the weighing and barcode scanning device as described above. This packaging system can be used manually to weigh and scan the product to be tested, or it can be automated by mechanical equipment.

[0085] In some embodiments, the packaging system further includes a robotic arm, a loading mechanism, and a unloading mechanism, which are respectively arranged upstream and downstream of the weighing and scanning device. The robotic arm is used to place the product to be tested, product trays, etc., on the loading mechanism onto the testing mechanism; and the robotic arm is configured to recognize audible and visual signals, and upon receiving the audible and visual signals, remove the entire stack of battery cells to complete the packaging.

[0086] The weighing and barcode scanning device and packaging system of this utility model simplify the barcode scanning and weighing process and improve work efficiency; moreover, the whole process is simple to operate and can be automated by using robotic arms to achieve packaging operations, saving labor costs.

[0087] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
