Next, with reference to the drawings, a loading table 200 according to an embodiment of the present invention is described. The feeding table 200 is used for detecting equipment, and the detecting equipment can be used for detecting defects of a piece to be detected and the like.

As shown in fig. 1, the loading table 200 includes a plurality of support ribs 101 arranged at intervals in a first direction (e.g., a front-rear direction in fig. 1), each support rib 101 extending in a second direction (e.g., a left-right direction in fig. 1), the first direction and the second direction being perpendicular.

Wherein, in the first direction, the width of brace rod 101 is x, the interval between two adjacent brace rods 101 is y, x, y satisfy 0.38 and are less than or equal to x/y and are less than or equal to 48, so that at least two brace rods 101 bear jointly and wait to detect the piece, guarantee that material loading platform 200 stably bears and wait to detect the piece, avoid waiting to detect that the piece easily takes place to twist, deflect etc., guarantee to detect the piece and keep its initial posture of placing at material loading platform 200 all the time, when material loading platform 200 is used for check out test set, be favorable to guaranteeing check out test set's detection accuracy.

For example, a width of the to-be-detected member in the first direction is greater than or equal to 50mm may be applicable to the feeding table 200 of the present application; for example, the width of the to-be-detected piece in the first direction is 50mm, the width of the supporting member 101 is 8mm, and the distance between two adjacent supporting ribs 101 is within the range of 0.16mm to 21mm, so that the to-be-detected piece can be jointly borne by at least two supporting ribs 101, and for the to-be-detected piece with the width greater than 50mm, the to-be-detected piece can be jointly borne by at least two supporting ribs 101.

According to the feeding table 200 provided by the embodiment of the invention, the ratio of the width x of the supporting rib 101 to the distance y between two adjacent supporting ribs 101 is equal to or greater than 0.38 and equal to or less than 48 by arranging the supporting ribs in the first direction, so that at least two supporting ribs 101 jointly bear the piece to be detected, the feeding table 200 is ensured to stably bear the piece to be detected, meanwhile, the feeding table 200 can be suitable for the pieces to be detected with different widths, and the feeding table 200 has good applicability.

In addition, through setting up material loading platform 200 to bear by a plurality of brace rods 101 and wait to detect the piece, can reduce material loading platform 200 and wait to detect the area of contact between the piece, reduce the risk that material loading platform 200 fish tail detected the piece, play the protection and wait the effect of detecting the piece, can reduce material consumption and the weight of material loading platform 200 in addition.

It is understood that the plurality of support ribs 101 may be uniformly spaced or non-uniformly spaced along the first direction.

In some embodiments, as shown in fig. 1, each support rib 101 includes a body 101a and a support member 101b, the support member 101b is disposed on the top of the body 101a, and the support member 101b is used to directly bear the to-be-detected member, so that the to-be-detected member may be separated from the body 101a by the support member 101b to directly contact with the to-be-detected member, and the support member 101b is a non-metal member (e.g., a plastic member, etc.), which may further prevent the loading platform 200 from scratching the to-be-detected member.

According to the feeding assembly 10 of the embodiment of the second aspect of the present invention, the feeding assembly 10 is used for a detection device, the detection device further comprises a conveying assembly 20, and the conveying assembly 20 can convey the to-be-detected piece along the second direction.

As shown in fig. 4 and 5, the feeding assembly 10 includes a frame 1, a first feeding table 2 and a second feeding table 3, at least one of the first feeding table 2 and the second feeding table 3 is a feeding table 200 according to the above first aspect of the present invention, and includes the following solutions: 1. the first loading table 2 is a loading table 200 according to the above-described first aspect embodiment of the present invention; 2. the second feeding table 3 is a feeding table 200 according to the above-described first aspect embodiment of the present invention; 3. the first and second loading tables 2, 3 are each a loading table 200 according to the above-described first aspect embodiment of the invention.

The first feeding table 2 and the second feeding table 3 are respectively movably arranged on the machine frame 1, and the first feeding table 2 can move relative to the machine frame 1 to convey the to-be-detected piece towards the conveying assembly 20. For example, the first loading table 2 can be moved between a first loading position, in which the pieces to be inspected can be transferred to the first loading table 2, and a loading position, adjacent to the transfer assembly 20, and in which the pieces to be inspected can be transferred to the transfer assembly 20, for example, from the first loading table 2 to the transfer assembly 20 by means of the gripping assembly 30 of the inspection device.

The second feeding table 3 can move to a preset position relative to the first feeding table 2 so as to convey the to-be-detected piece on the second feeding table 3 to the first feeding table 2. For example, the second feeding table 3 may be movable between a second loading position, at which the piece to be detected may be conveyed to the second feeding table 3 by a conveying mechanism or by an operator, and a predetermined position, to which the piece to be detected is driven by the second feeding table 3, and the piece to be detected may be transferred from the second feeding table 3 to the first feeding table 2.

Therefore, the movement of the first feeding table 2 and the second feeding table 3 can be reasonably set, for example, the time for moving the first feeding table 2 from the first loading position to the loading position can be utilized to convey the piece to be detected to the second feeding table 3, and the like, so that the continuous feeding of the feeding assembly 10 is realized, and the feeding efficiency is effectively ensured; moreover, by adopting the feeding table 200, the applicability of the feeding assembly 10 can be improved, so that the feeding assembly 10 can be suitable for the to-be-detected pieces in a wider size range.

In some embodiments, as shown in fig. 4-7, the first feeding table 2 can move along a third direction (e.g., up and down direction in fig. 4), and the third direction is perpendicular to the first direction and the second direction, so that the movement of the first feeding table 2 is simple, which is beneficial to simplifying the structure of the feeding assembly 10.

As shown in fig. 2 and 3, the second feeding table 3 and the first feeding table 2 are adapted to be disposed on the same side of the conveying assembly 20 in a first direction (e.g., a front-back direction in fig. 2), so that an occupied space of the feeding assembly 10 in the first direction can be saved, and a width of the feeding assembly 10 in the first direction can be reduced.

When the feeding assembly 10 is used for detecting equipment, compared with the technology that two feeding tables are respectively arranged on different sides of a conveying assembly in a second direction, each feeding table conveys a piece to be detected towards the conveying assembly and enables the two feeding tables to be sequentially and alternately conveyed through two clamping assemblies, the feeding assembly 10 can effectively reduce the width of the detecting equipment in the first direction, as shown in fig. 11 and 12, and the feeding assembly 10 and the conveying assembly 20 can be both arranged on a box body 50 of the detecting equipment, and in the second direction, a window can be arranged on one side of the box body 50 far away from the feeding assembly 10 for observation, maintenance and the like, because the second feeding table 3 and the first feeding table 2 are suitable for being positioned on the same side of the conveying assembly 20 in the second direction, the distance between the window on the box body 50 and the conveying assembly 20 is convenient to effectively reduce, and the convenience for an operator to maintain the conveying assembly 20 through the window is effectively improved, the maintenance of the detection equipment is facilitated, the feeding assembly 10 can be matched with one clamping assembly 30 to realize continuous conveying of the piece to be detected, the structure of the detection equipment is effectively simplified, and the cost is reduced.

It will be appreciated that, at the predetermined position, the second feeding table 3 and the first feeding table 2 are relatively movable in a third direction to transfer the object to be detected on the second feeding table 3 to the first feeding table 2. For example, when the second feeding table 3 moves to a predetermined position, the second feeding table 3 may remain stationary relative to the frame 1, and the first feeding table 2 may move in the third direction relative to the frame 1, so that the first feeding table 2 may take away the to-be-detected object on the second feeding table 3; for another example, when the second loading table 3 moves to the predetermined position, the first loading table 2 may remain stationary with respect to the frame 1, and the second loading table 3 may move in the third direction with respect to the frame 1, so that the object to be inspected on the second loading table 3 may be transferred to the first loading table 2.

The following description will be given taking the third direction as the up-down direction as an example: when the second feeding table 3 moves to a preset position, the second feeding table 3 can keep static relative to the rack 1, and the first feeding table 2 can move upwards to take away a piece to be detected on the second feeding table 3; alternatively, when the second feeding table 3 is moved to the predetermined position, the first feeding table 2 may be kept stationary with respect to the frame 11, and the second feeding table 3 may be moved downward, so that the to-be-detected member remains on the first feeding table 2 and is separated from the second feeding table 3 due to the blocking action of the first feeding table 2.

In some embodiments, as shown in fig. 4-7, the second feeding table 3 can move along a second direction (e.g., left and right direction in fig. 4), so that the second feeding table 3 has simple movement manner, which is beneficial to further simplify the structure of the feeding assembly 10; moreover, because the moving direction of second material loading platform 3 is perpendicular with the moving direction of first material loading platform 2, be convenient for guarantee to detect the piece from second material loading platform 3 conveying to the in-process of first material loading platform 2 wait to detect the posture of placing of piece remain unchanged all the time, avoid waiting to detect the piece because of receiving external force to take place to deflect etc. at above-mentioned in-process, influence the detection accuracy that detects the piece, can avoid detecting the piece and receiving frictional force, avoid detecting the piece fish tail that detects in addition.

For example, in the example of fig. 2 and 3, the two ends of the transfer assembly 20 in the second direction are a first end and a second end, respectively, the first feeding table 2 is adapted to be arranged at the first end of the transfer assembly 20, the second feeding table 3 moves between a second loading position and a predetermined position, and in the second loading position, the second feeding table 3 and the transfer assembly 20 are arranged in a staggered manner in the second direction, so that the second feeding table 3 extends to the side of the first end away from the second end, the occupied amount of the transfer assembly 20 in the space around the second feeding table 3 can be reduced, and the space around the second feeding table 3 can have enough operating space to quickly load materials to the second feeding table 3.

It will be appreciated that in the second loading position, the offset distance of the second loading table 3 from the transfer assembly 20 in the second direction may be specifically set according to actual requirements.

Of course, the movement manner of the second feeding table 3 is not limited thereto. For example, the second loading table 3 may also be pivotally connected to the frame 1, the second loading table 3 being rotatable between a second loading position and a predetermined position.

2. At least part of the first feeding table 2 is inserted into the second feeding table 3, and the part of the first feeding table 2 inserted into the second feeding table 3 can be used for receiving the piece to be detected transferred from the second feeding table 3; for example, the first loading platform 2 is the loading platform 200 according to the above-mentioned first aspect of the present invention, and includes a plurality of first supporting ribs 21 arranged at intervals along the first direction, and the plurality of first supporting ribs 21 may be inserted into the second loading platform 3.

3. At least part of the second feeding table 3 is inserted into the first feeding table 2, at least part of the first feeding table 2 is inserted into the second feeding table 3, the part of the second feeding table 3 inserted into the first feeding table 2 can be used for bearing the piece to be detected, and the part of the first feeding table 2 inserted into the second feeding table 3 can be used for bearing the piece to be detected transferred from the second feeding table 3; for example, the first feeding table 2 and the second feeding table 3 are both the feeding table 200 according to the above-described first aspect of the present invention, and the first feeding table 2 includes a plurality of first support ribs 21 arranged at intervals along the first direction, and the second feeding table 3 includes a plurality of second support ribs 31 arranged at intervals along the first direction.

In addition, as the second feeding table 3 is inserted and matched with the first feeding table 2 at a preset position, the first feeding table 2 and the second feeding table 3 are relatively close to each other in the first direction, a driving device for driving the second feeding table 3 to move is conveniently arranged on one side, far away from the conveying assembly 20, of the second feeding table 3, and the driving device cannot shield and interfere with the movement of the first feeding table 2, so that the reasonable layout of the feeding assembly 10 and the conveying assembly 20 is facilitated; meanwhile, for the side, opposite to the conveying assembly, of the second feeding table, at the preset position, at the interval of the first feeding table, the second feeding table 3 is arranged at the preset position in an inserting and matching mode with the first feeding table 2, the distance between the first feeding table 2 and the conveying assembly 20 in the first direction can be properly reduced, the moving distance of the first feeding table 2 is reduced, and the feeding efficiency is further improved.

In some embodiments, as shown in fig. 6 to 10, the first feeding table 2 and the second feeding table 3 are both the feeding table 200 according to the above first aspect of the present invention, the first feeding table 2 includes a plurality of first support ribs 21 spaced along the second direction, the second feeding table 3 includes a plurality of second support ribs 31 spaced along the second direction, and then in the first direction, the width of the first support rib 21 is x1, the distance between two adjacent first support ribs 21 is y1, 0.38 is equal to or greater than x1/y1 is equal to or less than 48, in the first direction, the width of the second support rib 31 is x2, the distance between two adjacent second support ribs 31 is y2, and 0.38 is equal to or greater than x2/y2 is equal to or less than 48.

At predetermined position, a plurality of first brace rods 21 and a plurality of second brace rods 31 are along the crisscross setting of second direction, then at predetermined position, can the interpolation between two at least adjacent first brace rods 21 have one or more second brace rods 31, and/or, can the interpolation between two at least adjacent second brace rods 31 have one or more first brace rods 21, thereby further guaranteed to detect the piece and steadily conveyed to first material loading platform 2 from second material loading platform 3, and second material loading platform 3 can not interfere the removal of first material loading platform 2.

It is understood that the plurality of first support ribs 21 may be uniformly spaced apart or non-uniformly spaced apart along the second direction; the plurality of second support ribs 31 may be disposed at uniform intervals or non-uniform intervals along the second direction.

Optionally, in preset position, a plurality of first brace rods 21 and a plurality of second brace rods 31 are along the crisscross setting of second direction one by one, then in preset position, be equipped with a second brace rod 31 between two adjacent first brace rods 21, and be equipped with a first brace rod 21 between two adjacent second brace rods 31, thereby when waiting to detect the piece and bearing by a plurality of second brace rods 31 jointly on second material loading platform 3, then be convenient for guarantee to detect that it also bears by a plurality of first brace rods 21 jointly to detect on conveying to first material loading platform 2, thereby it is stable not only to guarantee to detect the piece conveying, also be convenient for guarantee to detect the stability of placing of piece on second material loading platform 3 and first material loading platform 2.

In some embodiments, as shown in fig. 10, in the first direction, the width of the first support rib 21 and the width of the second support rib 31 are both x, and at the predetermined position, the distance between the adjacent first support ribs 21 and the second support rib 31 in the first direction is z, and z/x is greater than or equal to 0.38 and less than or equal to 1.125, so that the to-be-detected pieces with different sizes can be smoothly transferred from the second feeding table 3 to the first feeding table 2, and the to-be-detected pieces are jointly supported by at least two first support ribs 21 on the first feeding table 2.

In some embodiments, as shown in fig. 6 and 7, the second feeding table 3 can move relative to the first feeding table 2, and the first support rib 21 and the second support rib 31 both extend along the moving direction of the second feeding table 3, so as to ensure that the first feeding table 2 and the second feeding table 3 are smoothly inserted and assembled, and therefore the to-be-detected workpiece is stably conveyed.

It can be understood that, first support muscle 21 extends along the moving direction of second material loading platform 3, can indicate that the extending direction of first support muscle 21 is parallel or nonparallel with the moving direction of second material loading platform 3, for example there is certain contained angle between the extending direction of first support muscle 21 and the moving direction of second material loading platform 3, can guarantee the smooth of first material loading platform 2 and second material loading platform 3 to insert and join in marriage through the interval between the adjacent second support muscle 31 of reasonable setting this moment. The second support rib 31 is also disposed, and will not be described in detail herein.

In some embodiments, as shown in fig. 4 to 7, the feeding assembly 10 further includes a detecting device 4, and the detecting device 4 is configured to detect whether the to-be-detected piece is placed on the second feeding table 3, so as to facilitate automatic feeding of the feeding assembly 10 without frequent operation by an operator. For example, the detecting device 4 detects that the second feeding table 3 has placed the piece to be detected, and determines that the feeding is completed, and if the detecting device 4 determines that the piece to be detected is not on the first feeding table 2, the second feeding table 3 can move towards the predetermined position to drive the first feeding table 2 to be detected.

Optionally, the detection device 4 is an optical fiber sensor, and when the to-be-detected piece is placed on the second feeding table 3, the to-be-detected piece can shield the light beam to change the optical property of the light beam; or, the detecting device 4 is a weight sensor, and when the piece to be detected is placed on the second feeding table 3, the detecting device 4 can measure the weight of the piece to be detected.

It is understood that the position of the detecting device 4 may be set according to practical applications, for example, when the detecting device 4 is an optical fiber sensor, the detecting device 4 may be set in the rack 1 and corresponding to the second feeding table 3.

For example, as shown in fig. 8, the second feeding table 3 further includes a bottom plate 32, the bottom plate 32 is disposed at the bottom of the plurality of support ribs 31, and the bottom plate 32 is fixedly connected to the plurality of second support ribs 31, so that the plurality of second support ribs 31 move synchronously. The second feeding table 3 is matched with the rack 1 in a sliding mode through a sliding assembly 5, the sliding assembly 5 comprises a guide rail 51 and a sliding block 52, the guide rail 51 is fixedly arranged on the rack 1, and the sliding block 52 is fixedly arranged at the bottom of the second feeding table 3; the frame 1 is provided with a first driving device 8, and the first driving device 8 is used for driving the second feeding table 3 to move and comprises a driving motor 81 and a ball screw mechanism 82.

Optionally, the second feeding table 32 includes a plurality of sub-feeding tables spaced along the second direction, so as to reduce the weight of each sub-feeding table, and facilitate processing, moving, and mounting, and each sub-feeding table includes a plurality of second support ribs 31 and a sub-bottom plate connected to the bottoms of the plurality of second support ribs 31.
