[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0011] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0013] In production sites in logistics, industry, and medical fields, it is usually necessary to use automatic inspection equipment to inspect products on the production line. There are many items to be inspected, including weight inspection. However, the weighing devices of current automatic inspection equipment usually have a corresponding range. When the weighing device bears a heavy product that exceeds its own range, its internal weighing sensor is easily damaged, resulting in failure and ultimately causing the weighing result to be distorted.

[0014] The core component of a load cell is usually a strain gauge structure. When the strain gauge structure is subjected to excessive pressure, it cannot rebound to its initial state, which leads to malfunction. Therefore, those skilled in the art urgently need to find a solution that can prevent excessive deformation of the strain gauge structure of the load cell.

[0015] In view of this, the present invention provides a weighing structure, an online weighing device, and an automatic detection equipment, which can at least improve the problem that the weighing device of the current automatic detection equipment is prone to failure, resulting in inaccurate weighing results.

[0016] To facilitate understanding of the weighing structure, online weighing device, and automatic detection equipment provided by this utility model, the following description is provided in conjunction with the accompanying drawings, wherein... Figure 1 A schematic diagram of an embodiment of the automatic detection device provided by this utility model; Figure 2 A schematic diagram of an embodiment of the online weighing device provided by this utility model; Figure 3 for Figure 2 Exploded view of the online weighing device; Figure 4 for Figure 3 A schematic diagram of the main structure of the weighing structure.

[0017] Please see below Figure 3 and Figure 4 In one embodiment of this utility model, the weighing structure 3 includes a mounting base 32, a weighing sensor 31, and a stop limiting member 33; the weighing sensor 31 has a weighing end 311 and a mounting end 312 in the horizontal direction, the mounting end 312 is disposed on the mounting base 32, the weighing end 311 is configured to receive the weighed product, and the weighing end 311 has a weighing travel in the vertical direction X; the stop limiting member 33 is disposed on one of the mounting base 32 and the weighing end 311, and defines a limiting interval 33a between the stop limiting member 33 and the other in the vertical direction X, the limiting interval 33a is configured to limit the weighing travel of the weighing end 311.

[0018] The phrase "the load cell 31 has a weighing end 311 and a mounting end 312 in a horizontal direction" can also be understood as the load cell 31 extending horizontally, with the two ends respectively set as the weighing end 311 and the mounting end 312; the weighing end 311 is configured to receive weighed products, which can be understood as the weighing end 311 directly or indirectly receiving weighed products, wherein the indirect receiving method includes setting a weighing tray on the weighing end 311 and using the weighing tray to receive weighed products.

[0019] Between the weighing end 311 and the mounting end 312, the load cell 31 typically also has a strain structure. The strain structure is designed to undergo elastic deformation when subjected to pressure and to return to its natural state when the pressure is removed. Based on this, the weighing end 311 has a weighing travel in the vertical direction X when receiving the weighed product. The "weighing travel" refers to the maximum travel that the weighing end 311 can move downward relative to the mounting end 312. This weighing travel reflects the maximum range of the load cell 31.

[0020] The stop and limit member 33 can be set on the mounting base 32 and define a limit interval 33a between it and the weighing end 311 in the vertical direction X, or it can be set on the weighing end 311 and define a limit interval 33a between it and the mounting base 32 in the vertical direction X. This embodiment does not limit this. "The limit interval 33a is configured to limit the weighing movement stroke of the weighing end 311" should be understood as the size of the limit interval 33a should be the maximum downward displacement that the weighing end 311 can move. That is, when the weighing end 311 moves downward to the maximum weighing movement stroke, the stop and limit member 33 can limit its further downward movement.

[0021] In the technical solution provided by this utility model, the weighing sensor 31 extends horizontally and has a weighing end 311 and a mounting end 312. During the process of receiving the product to be weighed, the weighing end 311 moves at different amplitudes in the vertical direction X according to the weight of the product, and has a weighing stroke corresponding to the maximum range of the weighing sensor 31. When the weight of the product to be weighed is within the maximum range of the weighing sensor 31, due to the existence of the limiting interval 33a, the weighing end 311 of the weighing sensor 31 can move freely in the vertical direction X and weigh the weight of the product. When the weight of the product to be weighed exceeds the maximum range of the weighing sensor 31, due to the existence of the stop limiting member 33, the weighing end 311 of the weighing sensor 31 can be prevented from moving further downwards, thereby providing overload protection for the strain structure of the weighing sensor 31, preventing irreversible deformation, and improving the problem of easy failure of the weighing device in current automatic detection equipment, leading to distorted weighing results.

[0022] In some embodiments, the stop limit member 33 is disposed on the mounting base 32, and an adjustment structure is provided between the stop limit member 33 and the mounting base 32. The adjustment structure is configured to adjust the position of the stop limit member 33 along the vertical direction X to change the size of the limit interval 33a.

[0023] The function of the "adjustment structure" is to adjust the position of the stop limit member 33 in the vertical direction X and change the size of the limit interval 33a. There are various specific structural forms. For example, the adjustment structure includes an adjustment column set in the stop limit member 33 and an adjustment hole set in the mounting base 32. The adjustment column can move in the vertical direction X in the adjustment hole and is fixed in the corresponding position by a locking bolt that extends laterally to the adjustment hole. This embodiment does not limit the specific structural type of the adjustment structure.

[0024] In the above technical solution, by setting an adjustment structure between the stop limit member 33 and the mounting base 32, the position of the stop limit member 33 in the vertical direction X can be adjusted, thereby changing the size of the limit interval 33a, so as to compensate for the installation accuracy error between the mounting end 312 of the load cell 31 and the mounting base 32, and ensure that the limit interval 33a and the weighing end 311 of the load cell 31 are accurately matched.

[0025] In some embodiments, the adjustment structure includes a stud 331 disposed on the stop limit member 33 and a threaded hole disposed on the mounting base 32. The stud 331 extends in the vertical direction X and is connected to the threaded hole.

[0026] In the above technical solution, the stop limiter 33 and the mounting base 32 are connected in an adjustable manner by means of a stud 331 and a threaded hole. This adjustable method is stepless adjustment, which further improves the adjustment accuracy of the stop limiter 33 in the vertical X direction.

[0027] Specifically, the stop limit member 33 can be set as a stop limit bolt.

[0028] In some embodiments, the weighing end 311 of the load cell 31 is provided with a receiving member 34, the upper end of the receiving member 34 being configured to receive the weighed product; wherein, a limiting interval 33a is formed between the lower end of the receiving member 34 and the stop limiting member 33.

[0029] The "receiving component 34" is fixedly installed on the weighing end 311. When the product to be weighed is overweight, it can transfer the gravity to the weighing end 311 of the load cell 31 and the stop limit component 33 respectively. There are several ways to fix the receiving component 34 to the weighing end 311. For example, the receiving component 34 is provided with a slot in the middle of the vertical direction X. The slot is provided horizontally and the weighing end 311 of the load cell 31 is adapted to be inserted into the slot.

[0030] In the above technical solution, the weighing end 311 of the load cell 31 can indirectly support the product to be weighed through the receiving member 34. Since the limiting interval 33a is formed between the lower end of the receiving member 34 and the stop limiting member 33, when the product to be weighed is overweight, the gravity exceeding the maximum load capacity of the load cell 31 can be transmitted to the stop limiting member 33 through the lower end of the receiving member 34, thus avoiding direct contact between the weighing end 311 of the load cell 31 and the stop limiting member 33, which would otherwise damage the weighing end 311.

[0031] In some embodiments, the weighing end 311 of the load cell 31 is provided with a clearance hole 311a extending in the vertical direction X; the receiving member 34 includes a connecting bolt 342 and a receiving body 341, the connecting bolt 342 is connected to the receiving body 341 through the clearance hole 311a, and is configured to clamp the weighing end 311 in conjunction with the receiving body 341; wherein, the limiting interval 33a is formed between the connecting bolt 342 and the stop limiting member 33.

[0032] "The connecting bolt 342 is connected to the receiving body 341 through the relief hole 311a and is configured to clamp the weighing end 311 in conjunction with the receiving body 341" means that the threaded part of the connecting bolt 342 extends into the relief hole 311a and is threadedly connected to the receiving body 341, while the threaded head part of the connecting bolt 342 is configured to clamp the weighing end 311 in conjunction with the receiving body 341.

[0033] In the above technical solution, the connecting bolt 342 and the receiving body 341 are connected by a relief hole 311a provided in the weighing end 311. The relief hole 311a can provide a limit in any horizontal direction for the receiving part 34. The thread head of the connecting bolt 342 can cooperate with the receiving body 341 to clamp the weighing end 311 of the load cell 31, thereby providing a limit in the vertical X direction for the receiving part 34 and ensuring that the receiving part 34 is stably installed on the weighing end 311 of the load cell 31.

[0034] In some embodiments, the weighing sensor 31 is configured as a bellows sensor 31a.

[0035] In the above technical solution, the bellows sensor 31a works based on the bending beam principle. When the weighing end 311 is subjected to force, the surface of the strain structure in the middle will produce a large deformation. This makes the bellows sensor 31a very sensitive to weight changes and can output a strong signal. Moreover, the bellows sensor 31a has small creep and small zero drift during long-term use and can maintain stable weighing performance for a long time.

[0036] In some embodiments, the mounting end 312 of the bellows sensor 31a is provided with a horizontally extending wire connector 3121; the mounting end 312 is also provided with a wire harness protection plate 3122, which is located above the wire connector 3121.

[0037] "Wire connector 3121" is a connector used to connect to external signal lines and power supply lines.

[0038] In the above technical solution, a wire harness protection plate 3122 is provided above the wire connector 3121. The wire harness protection plate 3122 can provide shielding for the external lines connected to the wire connector 3121, preventing other components in the environment from touching the wire connector 3121 and causing fluctuations in the output of the weighing signal, which is beneficial to improving the weighing reliability of the weighing structure 3.

[0039] In some embodiments, the mounting base 32 includes a mounting body 321 and a pad 322, with the pad 322 disposed at the upper end of the mounting body 321; wherein, the mounting end 312 of the weighing sensor 31 is disposed on the pad 322, and the stop limiting member 33 is disposed on the mounting body 321.

[0040] In the above technical solution, a pad 322 is provided at the upper end of the mounting body 321. The pad 322 can raise the overall height of the weighing sensor 31, thereby ensuring that the weighing end 311 of the weighing sensor 31 can move normally in the vertical direction X without obstruction.

[0041] In other embodiments, a clearance groove may be provided on the mounting base 32 at the position corresponding to the weighing end 311 of the load cell 31, so as to provide clearance for the up and down movement of the weighing end 311 of the load cell 31.

[0042] On the other hand, please see Figure 2 and Figure 3 In one embodiment of this utility model, the online weighing device 100 includes a mounting bracket 1, a conveying device 2, and a weighing structure 3. The conveying device 2 includes a conveying bracket 21 and a conveying assembly 22. The conveying bracket 21 is disposed at the upper end of the mounting bracket 1, and the conveying assembly 22 is disposed on the conveying bracket 21. The conveying assembly 22 has an upper conveying end, which is configured to convey products horizontally. The weighing structure 3 is disposed between the conveying bracket 21 and the mounting bracket 1, and is configured to measure the real-time weight of the products conveyed by the conveying device 2. The function of the "conveying assembly 22" is to convey products horizontally. Its specific structural types are numerous. For example, the conveying assembly 22 can consist of multiple actively rotating rollers distributed horizontally, allowing the rollers to transfer products horizontally. Of course, the conveying assembly 22 can also be... Figures 1 to 3 As shown, a belt conveyor is used, but this embodiment is not limited to this. In practical applications, the conveying component 22 includes a horizontal input end and an output end. By connecting the input end and output end to the conveyor line, the product to be tested can be picked up from the conveyor line through the input end, and after weighing, the product can be returned to the conveyor line through its output end. The horizontal direction in which the conveying component 22 conveys the product can be the same as or different from the horizontal direction of the weighing sensor. Figure 3 As shown, the conveying assembly 22 conveys the product along the first horizontal direction Y, and the weighing sensor extends along the second horizontal direction Z.

[0043] Combining the description of "the conveyor bracket 21 being positioned at the upper end of the mounting bracket 1" and "the weighing structure 3 being positioned between the conveyor bracket 21 and the mounting bracket 1," it can be understood that the entire weight of the conveying device 2 is transferred to the mounting bracket 1 via the weighing structure 3. This includes the weight of the product conveyed by the conveying component 22. Therefore, the weighing structure 3 can measure the real-time weight of the product during the conveying process of the conveying device 2, including the total weight of the product and the conveying device 2, as well as the weight of the conveying device 2 itself. The individual weight of the product can be obtained by calculating the difference between the total weight and its own weight. There are many specific structural types of the "weighing structure 3," such as a weighing balance or a platform scale, which are not limited in this embodiment.

[0044] To ensure accurate weighing, the product to be tested is usually weighed separately by an online weighing device 100.

[0045] In the technical solution provided by this utility model, the front and rear ends of the conveying component 22 are respectively connected to the product conveying line. The conveying component 22 can continuously and uninterruptedly convey the product. During the process of conveying the product, since a weighing structure 3 is set between the conveying bracket 21 and the mounting bracket 1, the overall weight of the conveying device 2 during the process of conveying the product can be measured by the weighing structure 3. By comparing the overall weight with the weight of the conveying device 2 itself, the individual weight of the product can be determined. This truly realizes online measurement of product weight, has high measurement efficiency, and can also ensure the flow efficiency of the conveying line for the product, thus accelerating the production cycle.

[0046] In some embodiments, the conveying assembly 22 includes two rotating rollers and a conveyor belt. The two rotating rollers are spaced apart along a first horizontal direction Y and each has two mounting ends in a second horizontal direction Z. The two mounting ends are respectively mounted on the conveying bracket 21. The conveyor belt is wound around the two rotating rollers and includes a conveying end. The weighing structure 3 includes four weighing sensors 31, which are respectively disposed at the four mounting ends of the two rotating rollers.

[0047] Regardless of the structure of the rotating roller, it usually needs to be installed and positioned relative to the conveyor bracket 21 with the help of the mounting end. Based on this, "the four weighing sensors 31 are respectively set to correspond to the four mounting ends of the two rotating rollers" can be understood as the four weighing sensors 31 being set to overlap with the four mounting ends in the projection of the vertical direction X. Of course, the weighing sensors 31 can also have a certain positional offset relative to the mounting ends in the projection of the vertical direction X. For example, the four weighing sensors 31 can form a weighing area in the projection of the vertical direction X, and the four mounting ends of the two rotating rollers can fall into this weighing area.

[0048] In the above technical solution, the conveying component 22 is set as a combination of a conveyor belt and a rotating roller shaft. The rotating roller shaft drives the conveyor belt to smoothly convey the product, so that the fluctuation of the gravity parameter measured by the weighing structure 3 is small. On this basis, the weighing structure 3 is set as four weighing sensors 31, and the four weighing sensors 31 are respectively set to correspond to the four mounting ends of the two rotating roller shafts, so that the individual weight of the product can be accurately determined.

[0049] In some embodiments, the four weighing sensors 31 can measure the gravity distribution information of the conveying device 2 during the process of conveying the product. For example, when the position of the product entering the conveying component 22 is not the middle position of its second horizontal direction Z, the position of the product entering the conveying component 22 can be determined according to the gravity distribution information measured by the four weighing sensors 31 (for example, the position of the product entering the conveying component 22 can be determined to be the left front position). According to the gravity distribution information, the detection device in the detection component 200 of the automatic detection equipment can be controlled to adjust the detection direction, so as to detect the product as directly as possible (to detect towards the left front of the conveying component 22), which is beneficial to improve the detection accuracy of the detection device.

[0050] On the other hand, please see Figure 1 and Figure 2 In one embodiment of this utility model, the automatic detection device 1000 includes an online weighing device 100 and a detection component 200 as described in any of the above embodiments. The detection component 200 is disposed on the mounting bracket 1 of the online weighing device 100. The detection component 200 includes at least a barcode scanning device 210 and a photodetector 220, which are respectively positioned facing the conveying component 22 of the online weighing device 100. The specific structure of the online weighing device 100 is as described in the above embodiments. Since the automatic detection device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The barcode scanning device 210 and the photodetector 220 can respectively acquire the product's identification code information and appearance information. Specifically, the barcode scanning device 210 can be a barcode scanner, and the photodetector 220 can be a CCD camera with a light source.

[0051] In the technical solution provided by this utility model, the self-feeding testing equipment is equipped with an online weighing device 100, a barcode scanning device 210 and an optical inspection device 220, which can automatically test the product and obtain information parameters such as its weight information, identification information and appearance information. The entire testing process is carried out online without manual intervention, which greatly improves production efficiency and saves production costs.

[0052] In some embodiments, the barcode scanning device 210 and the optical inspection device 220 can automatically adjust their orientation according to the position of the product entering the conveying assembly 22, thereby accurately acquiring its identification and appearance information. Specifically, it can be installed on the mounting bracket 1 of the online weighing device 100 through a universal movable unit. The specific structural type of the "universal movable unit" can refer to the movable unit of the monitoring probe, and this embodiment of the utility model does not limit it in this way.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
