The carrying and conveying mechanism 220 is disposed on the first baffle 231 and the second baffle 232, for example, one of two first wheel sets of the carrying and conveying mechanism 220 is disposed on the first baffle 231, one of the first wheel sets is disposed on a side surface of the first baffle 231 facing the second baffle 232, the other of the two first wheel sets of the carrying and conveying mechanism 220 is disposed on the second baffle 232, the other first wheel set is disposed on a side surface of the second baffle 232 facing the first baffle 231, and the member 700 to be detected is disposed between the first baffle 231 and the second baffle 232. Here, the first and

second shutters

231 and 232 may restrict displacement of the member to be inspected 700 in a direction perpendicular to the moving direction of the carrier 200 (e.g., left and right directions as shown in fig. 5), and serve as a limiting and fixing function of the member to be inspected 700 in the direction.

The distance between the first baffle 231 and the second baffle 232 can be adjusted by moving the first baffle 231 and/or the second baffle 232 in this embodiment, so that the carrying device 200 can be suitable for the to-be-detected pieces 700 with different width dimensions, and thus, the application range of the detection apparatus 10 can be wider.

Preferably, the first guide bar 233 may include a plurality of first guide bars 233 which are disposed in parallel and at intervals in the moving direction of the carrier 200 (e.g., the front-rear direction shown in fig. 5). For example, as shown in fig. 5, the first guide rods 233 may include two, two first guide rods 233 extending in the left-right direction, two first guide rods 233 disposed in parallel and spaced apart in the front-rear direction, and the first and

second shutters

Wherein the first locking sleeve 234 is used for locking the first baffle 231 and/or the second baffle 232 to the first guide bar 233, or releasing the first baffle 231 and/or the second baffle 232 so that the first baffle 231 and the second baffle 232 can move relative to the first guide bar 233. That is, the first locking sleeve 234 has a first state and a second state, and is switchable between the first state and the second state, and the first locking sleeve 234 may lock the first shutter 231 or the second shutter 232 to the first guide bar 233 in the first state, and at this time, the first shutter 231 or the second shutter 232 is not movable with respect to the first guide bar 233. The first locking sleeve 234 may release the first blocking plate 231 or the second blocking plate 232 from the first guide bar 233 in the second state, and at this time, the first blocking plate 231 or the second blocking plate 232 may move relative to the first guide bar 233, so as to implement adjustment of the space between the first blocking plate 231 and the second blocking plate 232.

The first locking sleeve 234 is used for locking the first baffle 231 and the second baffle 232, so that the relative fixation between the first baffle 231 and the second baffle 232 and the first guide rod 233 can be ensured, the distance between the first baffle 231 and the second baffle 232 is kept unchanged, the deviation of the to-be-detected piece 700 is avoided, and the detection efficiency and the detection effect are ensured.

In this way, the pushing support plate 241 may be used to fix the first pushing driving piece 242, and the first pushing driving piece 242 may be used to drive the first baffle 231 and the second baffle 232 to move, so as to implement the adjustable space between the first baffle 231 and the second baffle 232, thereby implementing the automatic adjustment of the space between the first baffle 231 and the second baffle 232.

Wherein, referring to fig. 5, the pushing mechanism 240 may include only one pushing mechanism 240 is connected to the first plate 231 or the second plate 232 to drive the first plate 231 or the second plate 232 to move. When the interval between the first and

second shutters

In the process of adjusting the distance, only one of the baffles can be moved, and the first baffle 231 and the second baffle 232 can be driven to move by the two pushing mechanisms 240 at the same time, so that the distance between the two baffles can be adjusted, and the width requirement of the member 700 to be detected can be met.

Therefore, the interference between the pushing mechanism 240, the carrying and conveying mechanism 220 between the first baffle 231 and the second baffle 232 and the member 700 to be detected can be avoided, and the structure is simple and reasonable.

Alternatively, the first pushing actuator 242 may be a pushing cylinder or a pushing hydraulic cylinder. The first pushing driver 242 may be a servo motor, an electric cylinder, or the like.

In some specific examples, as shown in fig. 5, 7, and 9, the pushing mechanism 240 may further include: the locking block 243, the locking block 243 is provided on the pushing support plate 241, the locking block 243 has a released state and a locked state, the locking block 243 locks the pushing support plate 241 to the first guide rod 233 in the locked state, and the locking block 243 releases the pushing support plate 241 in the released state so that the pushing support plate 241 can move relative to the first guide rod 233.

Thereby, the pushing support plate 241 can be locked or released to the first guide bar 233 by the locking block 243.

When the fastener is completely fastened to the pushing support plate 241, the locking block 243 locks the pushing support plate 241 to the first guide bar 233, and when the fastener is loosened, the gap between the locking block 243 and the pushing support plate 241 increases, thereby releasing the pushing support plate 241 to the first guide bar 233, and at this time, the position of the pushing support plate 241 can be adjusted.

In some specific examples of the present invention, as shown in fig. 7 and 9, the carrier 200 may further include: the pressing plate mechanism 250, the pressing plate mechanism 250 includes a pressing plate 251 and a pressing driving member 252, the pressing plate 251 is disposed on the first baffle 231 and the second baffle 232, the pressing plate 251 is disposed on the upper side of the member 700 to be detected and is used for abutting the member 700 to be detected downwards, and the pressing driving member 252 is connected with the pressing plate 251 and is used for driving the pressing plate 251 to move along the up-down direction.

Preferably, as shown in fig. 7, the pressing plate mechanism 250 may include a plurality of pressing plate mechanisms 250 spaced apart on the first and

By providing the plurality of pressing plate mechanisms 250, the member 700 to be detected can be uniformly pressed in the circumferential direction of the member 700 to be detected, thereby improving the stability and reliability of fixing the member 700 to be detected.

Alternatively, the hold-down drive 252 may be a pneumatic or hydraulic cylinder. The pressing driver 252 may be a servo motor, an electric cylinder, or the like.

In one example, as shown in fig. 21, the first baffle 231 and the second baffle 232 are both provided with a receiving groove 2301 for receiving the pressing plate 251, a guiding hole is formed at a bottom wall of the receiving groove 2301, a guiding rod 253 is disposed at a bottom of the pressing plate 251, the guiding rod 253 is movably disposed in the guiding hole in a penetrating manner up and down, the pressing driving member 252 is connected to the guiding rod 253 for driving the guiding rod 253 to move, a boss 2511 extending in a horizontal direction is disposed on the pressing plate 251, and the boss 2511 is used for pressing the to-be-detected member 700 when the to-be-detected member 700 is in a to-be-detected state.

In some specific examples of the present invention, as shown in fig. 5, 11-18, the carrier 200 may further comprise: the blocking mechanism 260, the blocking mechanism 260 includes a blocking stopper 261 and a blocking driving member 262, the blocking stopper 261 is provided at one end of the first blocking stopper 231 and the second blocking stopper 232 in the length direction (for example, the rear ends of the first blocking stopper 231 and the second blocking stopper 232 shown in fig. 5), the blocking driving member 262 is connected to the blocking stopper 261 for driving the blocking stopper 261 to move between a blocking position (for example, the position of the blocking stopper 261 shown in fig. 13) and a retracted position (for example, the position of the blocking stopper 261 shown in fig. 12), the blocking stopper 261 abuts against the to-be-detected member 700 moved to the fixed position at one end of the first blocking stopper 231 in the length direction (for example, the rear end of the to-be-detected member 700 shown in fig. 7), the blocking stopper 261 is separated from the to-be-detected member 700 in the retracted position, and the blocking stopper 261 does not interfere with the movement of the to-be-detected member 700.

In this embodiment, by providing the blocking driving member 262 for driving the movement of the blocking member 261, on the one hand, the blocking mechanism 260 can be automatically abutted against the rear end edge of the member 700 to be detected, and on the other hand, when the member 700 to be detected is to be conveyed from the fixed position to the loading position (for example, the unloading position), the blocking member 261 can be moved to the retracted position by driving the blocking member 261 to separate the blocking member 261 from the member 700 to be detected in the front-rear direction, so that the blocking member 261 and the member 700 to be detected are no longer directly opposite to each other in the conveying direction of the member 700 to be detected, and thus the member 700 to be detected can be continuously conveyed to other positions without being blocked and interfered by the blocking member 261.

In some specific examples, the stop 261 is movable in an up-down direction, and the blocking position of the stop 261 is located above the retracted position, the blocking mechanism 260 may further include: a blocking push rod 263, one end of the blocking push rod 263 (e.g., the left end of the blocking push rod 263 shown in fig. 13) is connected to the blocking driver 262, and the other end of the blocking push rod 263 (e.g., the right end of the blocking push rod 263 shown in fig. 13) is engaged with the stopper 261. Thus, when the blocking mechanism 260 is operated, the blocking driving member 262 can drive the blocking push rod 263 to move, for example, can drive the blocking push rod 263 to move up and down or move horizontally, and the blocking push rod 263 further drives the stop block 261 to move up and down, so as to realize the movement between the blocking position and the retracted position. In this embodiment, by providing the blocking push rod 263, the blocking push rod 263 plays a role in transmitting force between the blocking driving member 262 and the stop 261, so that the overall structure of the blocking mechanism 260 can be more conveniently provided, and the structure is compact and reasonable.

In one example, as shown in fig. 12, the blocking push rod 263 extends in a horizontal direction (e.g., a left-right direction as viewed in fig. 12), an end of the blocking push rod 263 toward the stopper 261 (e.g., a right end of the stopper 261 as viewed in fig. 12) is formed with a blocking driving surface 2631 extending obliquely, a lower end of the stopper 261 is formed with a blocking engagement surface 2611 adapted in shape to the blocking driving surface 2631, and the blocking driving surface 2631 is in driving engagement with the blocking engagement surface 2611. In this way, when the blocking driving member 262 drives the blocking push rod 263 to move in the horizontal direction, the blocking driving surface 2631 and the blocking mating surface 2611, which cooperate to achieve the transmission of force, can convert the force of the horizontal movement of the blocking push rod 263 into the force of the movement of the stop block 261 in the vertical direction, thereby achieving the conversion of the direction of the force, and therefore, the blocking mechanism 260 can be more conveniently arranged, and the height of the blocking mechanism 260 in the vertical direction can be reduced.

Alternatively, the blocking driving surface 2631 is formed as a slope extending obliquely, and in particular, as shown in fig. 12, the upper surface of the right end of the blocking push rod 263 is formed with a slope extending obliquely downward and rightward, whereby the structure can be simplified and the processing can be facilitated. In another example, the blocking driving surface 2631 may be formed as an arc surface extending obliquely, for example, an upper surface of a right end of the blocking push rod 263 is formed with an arc surface extending obliquely downward and rightward, and the arc surface may be an arc surface recessed downward or an arc surface protruding upward.

In some specific examples, as shown in fig. 12, the blocking mechanism 260 may further include a blocking slider 264, a first guide channel 2641 and a second guide channel 2642 are formed on the blocking slider 264, the first guide channel 2641 extends in an up-down direction, the second guide channel 2642 extends in a horizontal direction, and the first guide channel 2641 and the second guide channel 2642 communicate, for example, the first guide channel 2641 is orthogonal to the second guide channel 2642. Further, a stopper 261 is movably provided in the first guide passage 2641, and the other end of the blocking push rod 263 (e.g., the right end of the blocking push rod 263 shown in fig. 12) is movably provided in the second guide passage 2642. Thus, when the blocking driving piece 262 drives the blocking push rod 263 to move along the horizontal direction, the second guiding channel 2642 can play a role in horizontally guiding and vertically limiting the movement of the blocking push rod 263, so that the blocking push rod 263 is prevented from being skewed, the movement stability of the blocking push rod 263 is ensured, and when the blocking push rod 263 drives the stop block 261 to move up and down, the first guiding channel 2641 can play a role in vertically guiding and horizontally limiting the movement of the stop block 261, and the stability of the stop block 261 in the moving process is ensured. The blocking slider 264 may be fixed to the first shutter 231 or the second shutter 232.

Alternatively, the second guide passage 2642 penetrates the blocking slider 264 in the horizontal direction, whereby it is possible to ensure that the blocking push rod 263 has a sufficient moving space, ensuring that the blocking push rod 263 can effectively drive the stopper 261 to the blocking position.

In one example, as shown in fig. 11, the stopper 261 is formed at an upper end thereof with a limit protrusion 2612 extending in a horizontal direction, and when the stopper 261 is at the retracted position, the limit protrusion 2612 is stopped against an outlet end of the first guide channel 2641 (for example, an upper end of the first guide channel 2641 in fig. 12) to limit a distance by which the stopper 261 moves downward, thereby achieving a limit effect on the stopper 261.

In one example, as shown in fig. 11, the blocking slider 264 has a downward concave limiting groove 2643 formed on an upper surface thereof, an outlet end of the first guide channel 2641 is formed on a bottom wall of the limiting groove 2643, and the limiting protrusion 2612 is stopped against the bottom wall of the limiting groove 2643 when the stopper 261 is in the retracted position. Like this, when dog 261 is in the shrink position, the part and the spacing arch 2612 of dog 261 not only can accomodate in spacing groove 2643, and spacing groove 2643's diapire can also limit dog 261 and continue the downwardly moving to limit the spacing to the spacing effect of dog 261 is realized to limit dog 261 downwardly moving's distance.

In one example, as shown in fig. 11 and 12, the blocking mechanism 260 may further include: and a reset piece connected between the blocking slide seat 264 and the stop block 261, wherein the reset piece has a force for driving the stop block 261 to move from the blocking position to the contraction position all the time. When the stop driving member 262 drives the stop 261 to move to the stop position and the stop 261 is required to retract, the reset member drives the stop 261 to retract to the retracted position by the self-force of the reset member, so that the stop 261 can retract automatically.

Alternatively, as shown in fig. 12, a first fixing groove 2613 recessed downward is formed on an upper surface of the stopper 261, a second fixing groove 2644 opposite to the first fixing groove 2613 up and down is formed on an outer surface of the blocking slider 264, the restoring member is formed as an annular elastic member 265, for example, the annular elastic member 265 is an elastic rubber ring or an annular spring, and the annular elastic member 265 is sleeved on the blocking slider 264 and the stopper 261 and is located in the first fixing groove 2613 and the second fixing groove 2644. When the stop block 261 is driven to move upwards, the annular elastic piece 265 is stretched, and when the upward driving force to the stop block 261 is removed, the annular elastic piece 265 is restored to deform, the stop block 261 is driven to move downwards, and automatic reset of the stop block 261 is achieved. Specifically, as shown in fig. 12, the restoring member is formed as an annular elastic member 265 extending in the circumferential direction of the blocking push rod 263, the annular elastic member 265 is fitted over the outer surface of the blocking slider 264, and the upper end of the annular elastic member 265 is fitted into the first fixing groove 2613 of the upper surface of the stopper 261, and the lower end of the annular elastic member 265 is fitted into the second fixing groove 2644 of the lower surface of the blocking slider 264. In this way, the first and second fixing

grooves

2613 and 2644 fix the upper and lower portions of the annular elastic member 265, respectively, to play a role in fixing and limiting the annular elastic member 265, thereby preventing the annular elastic member 265 from sliding on the outer surface of the blocking slider 264.

In another alternative example, as shown in fig. 18, a mounting groove 2614 extending in the up-down direction is formed in the stopper 261, a stopper 266 is fixed on the blocking slide 264, the stopper 266 is disposed in the mounting groove 2614 in a penetrating manner, the restoring member is a restoring spring 267 disposed vertically, one end of the restoring spring 267 (for example, a lower end of the restoring spring 267 shown in fig. 18) is fixed to the stopper 261, and the other end of the restoring spring 267 (for example, an upper end of the restoring spring 267 shown in fig. 18) abuts against the stopper 266. When the stopper 261 is driven to move upward, the stopper 266 compresses the return spring 267, and when the upward driving force to the stopper 261 is removed, the return spring 267 is restored to be deformed, pushing the stopper 261 to move downward, and automatic return of the stopper 261 is achieved.
