In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.
In a first aspect of the present invention, there is provided an object table, as shown in fig. 1 to 3, comprising:
the upper tray 1 is provided with a plurality of first limiting blocks 11, the first limiting blocks 11 are circumferentially arranged at intervals along the outer edge of the upper tray 1, and the upper tray 1 is used for bearing goods.
The lower tray 2 has a plurality of second stoppers 21 and a plurality of sensors 3. The second stoppers 21 are circumferentially spaced apart along the outer edge of the lower tray 2. Each second stopper 21 cooperates with each first stopper 11 to restrict the relative position of the upper tray 1 and the lower tray 2 in the horizontal direction. The first stopper 11 and the second stopper 21 cooperate with each other to realize the limitation of the upper tray 1 and the lower tray 2 by contacting each other or connecting each other. Each sensor 3 is arranged on the lower tray 2 (specific position arrangement is shown below), and the detection end of each sensor 3 can be contacted with the upper tray 1 for measuring the stress condition when the upper tray 1 carries goods. For example, the weight of the cargo, the position of the center of gravity of the cargo, and the like are measured. Preferably, each sensor 3 can only bear the vertical downward force from the upper tray 1 when in operation, namely only give upward supporting force to the upper tray 1, so as to ensure the accuracy of the detection result.
For ease of understanding, the upper portion shown in fig. 1 is set to an upper orientation, and the lower portion shown in fig. 1 is set to a lower orientation. The lower end surface of the upper tray 1 is set as described in fig. 2. As shown in fig. 3, the upper end surface of the lower tray 2. In fig. 1, the visible end surface of the upper tray 1 is an upper end surface, the invisible end surface is a lower end surface, the upper end surface of the upper tray 1 is used for carrying goods, and each first limiting block 11 is arranged on the lower end of the upper tray 1. In fig. 1, the visible end surface of the lower tray 2 is an upper end surface, the invisible end surface is a lower end surface, and the upper end surface of the lower tray is used for setting each second limiting block 21 and each sensor 3. And the lower end face of the upper tray 1 is opposite to the upper end face of the lower tray 2, i.e. the upper tray 1 is located above the lower tray 2, and the detection end of each sensor 3 on the lower tray 2 can support the lower end face of the upper tray 1.
In one embodiment, the upper tray 1 and the lower tray 2 are in non-fixed connection, that is, the upper tray 1 has gaps in the horizontal direction and the vertical direction relative to the lower tray 2, so that a certain activity allowance of the upper tray 1 is ensured, the influence of pretightening force generated by the fixed connection of the upper tray 1 and the lower tray 2 on weighing precision is avoided, and the accuracy of data related to goods acquired by each sensor on the object stage is improved.
For example, after the upper tray 1 and the lower tray 2 are assembled, a tiny gap exists between each first limiting block 11 and each corresponding second limiting block 12 (i.e. the first limiting block 11 and the corresponding second limiting block 12 are in non-fixed connection), so that a certain activity allowance is ensured on an area surrounded by each second limiting block 12 for the upper tray 1. The movable margin between the upper tray 1 and the lower tray 2 is at least ensured not to affect the relative fixation of the two.
In one embodiment, the sensors 3 are regularly and uniformly distributed on the lower tray 2, that is, each sensor 3 can support a stable plane, so that each sensor 3 can uniformly measure the stress of each position point on the upper tray 1, and the gravity center and the weight of the goods borne on the upper tray 1 can be accurately calculated, so that the condition of uneven stress of each sensor 3 is avoided. Preferably, the sensors 3 are uniformly distributed along the central circumference of the lower tray 2. For example, the wiring of each sensor 3 is arranged outside the center of the lower tray 2 in a regular polygonal or circular manner.
In one application example, when the lower tray 2 is rectangular, the sensors 3 are disposed at four corners of the rectangle, respectively. Each sensor 3 may also be located at a midpoint of each side of the rectangle. So long as the sensors 3 are guaranteed to be capable of uniformly measuring the stress condition of the upper tray 1.
In one embodiment, the number of the first limiting blocks 11 may not be identical to the number of the second limiting blocks 21 or may be in one-to-one correspondence. When the number of the first stoppers 11 is not identical to the number of the second stoppers 21, one first stopper 11 may be engaged with two or more second stoppers 21. Alternatively, one second stopper 21 may be engaged with two or more first stoppers 11.
In one embodiment, a plurality of vertical stoppers 4 are also included. Each vertical limiting block 4 is arranged between the upper tray 1 and the lower tray 2 at intervals and used for limiting the relative positions of the upper tray 1 and the lower tray 2 in the vertical direction. Each vertical limiting block 4 can be fixed on the lower tray 2 and limited by contact (or clearance) with the upper tray 1. Each vertical limiting block 4 can also be fixed on the upper tray 1 and limited by contact (or clearance) with the lower tray 2.

When the stage is in the non-operating state, the first end 41 is not pressed by the upper tray 1 and contacts with the end surface of the limiting step 121 under the supporting action of the sensor 3 (as shown in fig. 4). When the stage is in operation, the first end 41 is pressed against the upper tray and separated from the end surface of the stop step 121 (as shown in fig. 5).
As shown in fig. 6, the vertical stopper 4 may have a hollow column structure, and the first end 41 of the vertical stopper 4 forms a flange structure. The flange structure is erected on the limiting step 121, and the second end 42 of the vertical limiting block 4 is connected with the upper end face of the lower tray 2. The depth of the limiting hole 12 is greater than the thickness of the flange structure, so that the upper tray 1 can move up and down relative to the vertical limiting block 4.
In one embodiment, in order to improve the connection stability of the vertical stopper 4 and the lower tray 2, a bolt 42 may be inserted into the vertical stopper 4, and the vertical stopper 4 and the lower tray 2 may be firmly connected as one body by the bolt 42.
In one embodiment, the lower tray 2 is provided with a limiting hole (not shown in the figure), one end of the vertical limiting block 4 is slidably disposed in the limiting hole, and the other end of the vertical limiting block 4 is connected to the upper tray 1, so that the upper tray 1 can move in the vertical direction with respect to the lower tray 2.
