However, the current material boxes are of different sizes, and the method of relying on manual detection of material box sizes is no longer sufficient. However, in the face of a wide variety of material boxes with different specifications, relying solely on manual detection of material box sizes has revealed obvious shortcomings: not only is the accuracy limited, resulting in low work efficiency, but the influence of subjective factors makes it impossible to maintain the consistency and accuracy of the measurement results constantly, which is not conducive to stable and efficient production.

[0031] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be understood that the terms "connected", "connected", "fixed" and the like used in the present invention should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a welding connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The present invention uses the terms "first", "second", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0035] In the description of the present invention, the first direction is the Y-axis direction, the second direction is the Z-axis direction, and the third direction is the X-axis direction; at the same time, in the present invention, the second direction can also be expressed as an up and down direction, wherein the first direction, the second direction and the third direction are perpendicular or approximately perpendicular to each other.

[0036] Reference Figure 1 and Figure 2 , an automatic detection device according to an embodiment of the present invention comprises: a frame 1, a Y-axis motion mechanism 2, a Z-axis motion mechanism 3, an opening and closing clamping mechanism 4, a material incoming mechanism 5 and a laser sensor 6;

[0037] The material incoming mechanism 5 and the opening and closing clamping mechanism 4 are sequentially arranged on the frame 1 along the first direction Y, and the opening and closing clamping mechanism 4 is sequentially connected to the frame 1 through the Z-axis motion mechanism 3 and the Y-axis motion mechanism 2. The opening and closing clamping mechanism 4 can move relative to the frame 1 along the second direction Z through the Z-axis motion mechanism 3, and the opening and closing clamping mechanism 4 can move relative to the frame 1 along the first direction Y through the Y-axis motion mechanism 2.

[0038] The material incoming mechanism 5 is provided with a material incoming port 51 along the first direction Y toward the opening and closing clamping mechanism 4, the opening and closing clamping mechanism 4 includes a material box in-place sensor 41, and a first clamping portion 42 and a second clamping portion 43 both facing the material incoming port 51, the first clamping portion 42 and the second clamping portion 43 are arranged at intervals along the second direction Z, and the first clamping portion 42 and the second clamping portion 43 can approach or move away from each other along the second direction Z to achieve clamping, the material box in-place sensor 41 is arranged between the first clamping portion 42 and the second clamping portion 43 and is arranged toward the material incoming port 51, and the laser sensor 6 is arranged between the material incoming port 51 and the opening and closing clamping mechanism 4.

[0039] Specifically, the laser sensor 6 is spaced apart from the opening and closing clamping mechanism 4 along the third direction X, and its detection end is oriented toward the middle between the material inlet 51 and the opening and closing clamping mechanism 4 along the third direction X. The automatic detection and clamping device also includes a control device, which is communicatively connected with the Y-axis motion mechanism 2, the Z-axis motion mechanism 3, the opening and closing clamping mechanism 4, the laser sensor 6, and the material inlet mechanism 5.

[0040] The laser sensor 6 is the main functional mechanism for realizing object size detection and size calculation. The control device obtains the rising edge signal and the falling edge signal of the laser sensor 6, and determines the size of the material box in the first direction Y by calculating the distance traveled by the Y-axis servo motor 23 in the Y-axis motion mechanism 2 during the process. Similarly, if necessary, the size of the material box in the second direction Z can also be detected in this way.

[0041] The laser sensor can directly detect the size of the material box in the first direction Y, and is not affected by the size of the material box in other directions, so as to solve the problem of misplacing different material boxes in the production process and play a fool-proofing function. The device can also control the movement of the material box in the second direction Z through the Z-axis motion mechanism 3, and cooperate with the laser sensor 6 to detect whether there is material in the material box. If there is material in the material box, an alarm is issued; in addition, it can also be used to detect whether there is material overlap. If there is material in the material box and there is overlap, an alarm can also be issued to solve manual negligence.

[0042] Reference Figure 3In some improved schemes of the present application, the Y-axis motion mechanism 2 includes a first mounting seat 21, a first bracket 22, a Y-axis servo motor 23, and a first screw rod 24 and a first guide rail 25 both extending along the first direction Y, the first mounting seat 21 is fixed on the frame 1, the first guide rail 25 and the first screw rod 24 are both arranged on the first mounting seat 21, the Y-axis servo motor 23 is transmission-connected to the first screw rod 24, the first bracket 22 is movably connected to the first mounting seat 21 through the first screw rod 24 and the first guide rail 25, and the first bracket 22 can move relative to the first mounting seat 21 along the first direction Y, and the Z-axis motion mechanism 3 is arranged on the first bracket 22. The Y-axis motion mechanism 2 can drive the Z-axis motion mechanism 3 and the opening and closing clamping mechanism 4 to make horizontal linear motion along the first direction Y on the frame 1 as a whole. When clamping, the Y-axis servo motor 23 controls the movement of the first bracket 22 to align the clamping part with the accurate position of the object to be clamped. When it is necessary to release and drop the object to be clamped, the Y-axis motion mechanism 2 is also used to adjust the position in the Y-axis direction to an accurate and appropriate position.

[0043] In some improved solutions of the present application, the Y-axis motion mechanism 2 further includes at least three Y-axis position sensors 26, which are sequentially arranged on the first mounting seat 21 at intervals along the first direction Y. The three Y-axis position sensors 26 can be used to define whether the first bracket 22 has returned to the origin, and to limit the positive and negative positions of the first bracket 22, respectively, to play a role in safety protection.

[0044] Reference Figure 4 In some improved schemes of the present application, the Z-axis motion mechanism 3 includes a second mounting seat 31, a second bracket 32, a Z-axis servo motor 33, and a second screw rod and a second guide rail 35 both extending along the second direction Z, the second mounting seat 31 is fixed on the first bracket 22, the second guide rail 35 and the second screw rod are both arranged on the second mounting seat 31, the Z-axis servo motor 33 is transmission-connected to the second screw rod, the second bracket 32 ​​is movably connected to the second mounting seat 31 through the second screw rod and the second guide rail 35, and the second bracket 32 ​​can move along the second direction Z relative to the second mounting seat 31, and the opening and closing clamping mechanism 4 is arranged on the second bracket 32.

[0045] The Z-axis motion mechanism 3 has the same principle as the Y-axis motion mechanism 2. When the clamping part clamps an object or needs to place the object at a specified position, if there is a difference in the position in the second direction Z, the Z-axis servo motor 33 can drive the opening and closing clamping mechanism 4 and the clamped object to rise or fall as a whole to a suitable position; at the same time, the Z-axis servo motor 33 controls the movement of the second bracket 32 ​​and can also control the up and down displacement of the first clamping part 42 in the opening and closing clamping mechanism 4 in the second direction Z.

[0046] The Z-axis motion mechanism 3 further includes at least three Z-axis position sensors 36, which are sequentially arranged on the second mounting seat 31 at intervals along the second direction Z. The three Z-axis position sensors 36 are also used to determine whether the second bracket 32 ​​has returned to the origin, and to limit the positive and negative positions of the second bracket 32, thereby playing a role of safety protection.

[0047] In some improved solutions of the present application, the opening and closing clamping mechanism 4 includes a Z-axis progressive motor 44, a clamping position sensor 46, and a third screw rod 47 and a third guide rail 48 both extending along the second direction Z. The third screw rod 47 and the third guide rail 48 are both arranged on the second bracket 32. The first clamping portion 42 is fixed to one end of the second bracket 32 ​​along the second direction Z. The second clamping portion 43 is movably connected to the other end of the second bracket 32 ​​through the third guide rail 48 and the third screw rod 47. The second clamping portion 43 can approach or move away from the first clamping portion 42 along the second direction Z. The clamping position sensor 46 is arranged on the second clamping portion 43. Specifically, the first clamping portion 42 is located below the second clamping portion 43. The principle of the opening and closing clamping mechanism 4 is roughly the same as that of the Z-axis motion mechanism 3. When clamping, the opening and closing clamping mechanism 4 performs fine adjustment synchronously after the Z-axis motion mechanism 3 is positioned, and the second clamping portion 43 is driven by the Z-axis progressive motor 44 to move up and down in the second direction Z to realize the clamping function.

[0048] In some improved solutions of the present application, the opening and closing clamping mechanism 4 further includes at least three clamping position sensors 49, which are arranged on the second bracket 32 ​​in sequence and at intervals along the second direction Z. The three clamping position sensors 49 are also used to define whether the mechanism has returned to the origin and to limit its positive and negative limit positions, thereby playing a role in safety protection.

[0049] Reference Figure 5 In some improved solutions of the present application, the material incoming mechanism 5 includes a conveyor belt 52 extending along the first direction Y, and one end of the conveyor belt 52 facing the opening and closing clamping mechanism 4 is defined as the material incoming port 51.

[0050] In some improved schemes of the present application, a discharging mechanism 7 is further included, and the discharging mechanism 7 is arranged on the frame 1, and the discharging mechanism 7 and the incoming material mechanism 5 are arranged at intervals along the second direction Z. Specifically, the incoming material mechanism 5 is arranged on the upper layer of the discharging mechanism 7. The incoming material mechanism 5 and the discharging mechanism 7 are both used to convey material boxes. The incoming material mechanism 5 is located on the upper layer for conveying empty material boxes to receive materials, and the discharging mechanism 7 is arranged on the lower layer for recovering full material boxes. When production is started, the empty material box of the incoming material mechanism 5 is clamped and moved to the guide rail docking position under the cooperation of the Y-axis motion mechanism 2, the Z-axis motion mechanism 3 and the opening and closing clamping mechanism 4. During this process, the laser sensor 6 performs detection work synchronously, and records the size of the material box in the first direction Y by recording the position of the motor.

[0051] A preferred embodiment of the present invention provides an automatic detection method, which is used in the above-mentioned automatic detection device, and comprises the following steps:

[0052] S1 Before carrying out automatic production inspection, power on the automatic inspection equipment and perform program debugging;

[0053] S2 places the material box on the material incoming mechanism 5 and starts the automatic detection equipment. The conveyor belt 52 on the material incoming mechanism 5 transports the material box to the material incoming port 51 until the material box arrival sensor 41 is sensed. After the material box arrival sensor 41 detects the presence of the material box, the conveyor belt stops.

[0054] S3 The opening and closing clamping mechanism 4 adjusts its position through the Y-axis motion mechanism 2 and the Z-axis motion mechanism 3, and moves toward the material inlet 51, so that the material box is located between the first clamping part 42 and the second clamping part 43; at this time, the Y-axis servo motor 23 continues to control the opening and closing clamping mechanism 4 to move toward the material box until the opening and closing clamping mechanism 4 is close to the material box; at this time, the material box in-place sensor 41 lights up, indicating that it is close to the material box.

[0055] S4 The Z-axis servo motor 33 and the Z-axis stepper motor synchronously control the first clamping part 42 and the second clamping part 43 to clamp the material box, and move it upward along the second direction Z to the preset safety position; the Y-axis servo motor 23 controls the opening and closing clamping mechanism 4 to clamp the material box and move it along the first direction Y toward away from the material inlet 51. When the material box enters the sensing area of ​​the laser sensor 6, the laser sensor 6 obtains a rising edge signal, triggering the laser sensor 6 to change from the OFF state to the ON state, and the control device synchronously records the current position value of the motor as the first position value; the Y-axis servo motor 23 continues to control the material box to move in the direction away from the material inlet 51. When the material box leaves the sensing area of ​​the laser sensor 6, the laser sensor 6 changes from the ON state to the OFF state again, and the laser sensor 6 obtains a falling edge signal, and the control device synchronously records the current position value of the motor as the second position value.

[0056] S5 subtracts the first position value from the second position value to obtain the size of the material box in the first direction Y and compares it with the initially preset material box size. If the values ​​are the same, the material box is placed correctly; if the values ​​are different, the material box is placed incorrectly, and the control device prompts an alarm message to facilitate the operator to replace the correct material box in time.

[0057] This detection method can detect in advance whether the operator has placed the material box correctly, which can not only reduce losses but also detect operating errors of operators, saving time and is not affected by the size of the material box in other directions.

[0058] In some improved solutions of the present application, when the material box is placed correctly in S5, the following steps are performed:

[0059] The material strips are placed in the material box along the first direction Y, and the material box is controlled to rise and fall through the Z-axis motion mechanism 3, and the laser sensor 6 is used to synchronously determine whether the material strips overflow from the material box; if the material strips overflow, the signal of the laser sensor 6 changes, and the control device obtains the signal of the laser sensor 6 and sends a prompt message.

[0060] When the placed material box is an empty material box, in addition to calculating the size of the material box, it is also possible to control the lifting and lowering of the Z-axis servo motor 33 to detect whether there is excess material in the material box to avoid stacking of materials. The detection is performed layer by layer. If material is found, the laser sensor 6 will have a signal change and a prompt will be given on the software, and then manual intervention will be performed.

[0061] In summary, the embodiment of the present invention provides an automatic detection device, which can clamp the material box by utilizing the Y-axis motion mechanism 2, the Z-axis motion mechanism 3 and the opening and closing clamping mechanism 4, and determine the accurate size of the material box in the first direction Y through the rising edge and falling edge signals of the laser sensor 6, which is not affected by the thickness of the material box, that is, the size in the second direction Z; the device is simple and convenient to use, and only needs to pre-set the template of the corresponding batch. When using it, the position can be adjusted to repeatedly and quickly perform functions such as clamping, carrying, detection and placement, which can ensure the accuracy of the detection results, avoid errors and instability caused by manual detection, and improve work efficiency.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.

The conveyor belt on the material inlet mechanism transports the material box to the material inlet until the material box in place sensor is sensed; S3 The opening and closing clamping mechanism adjusts the position through the Y-axis motion mechanism and the Z-axis motion mechanism so that the material box is located between the first clamping part and the second clamping part, and the opening and closing clamping mechanism moves toward the material box through the Y-axis motion mechanism until it is close to the material box; S4 The opening and closing clamping mechanism clamps the material box, and controls the material box to move along the first direction away from the material inlet through the Y-axis motion mechanism. When the material box enters the sensing area of ​​the laser sensor, the laser sensor obtains a rising edge signal, and the control device synchronously records the current position value of the motor as the first position value; when the material box leaves the sensing area of ​​the laser sensor, the laser sensor obtains a falling edge signal, and the control device synchronously records the current position value of the motor as the second position value; S5 subtracts the first position value from the second position value to obtain the size of the material box in the first direction and compares it with the preset material box size. If the values ​​are the same, the size of the placed material box is correct; if the values ​​are different, the size of the placed material box is incorrect, and the control device prompts an alarm message.

10. The automatic detection method according to claim 9, characterized in that: It also includes the following steps when the material box is placed correctly in S5: The material strips are placed in the material box, and the Z-axis motion mechanism is used to control the lifting of the material box. At the same time, the laser sensor is used to synchronously determine whether the material strips overflow from the material box; if the material strips overflow, the laser sensor signal changes, and the control device obtains the laser sensor signal and sends a prompt message.
