If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] It should be noted that the material box includes a box body and a box cover. The box mouth of the box body is arranged on the side wall of the box body. The two opposite ends of the box cover respectively form a hinged end and a movable end. The hinged end is hinged to the edge of the box mouth on one side in the width direction, and the movable end is clamped to the edge of the box mouth on one side in the width direction. An inner box is placed in the box body.

[0034] refer to Figure 1 and Figure 3 According to some embodiments of the utility model, the box opening device includes a positioning component 100, an unlocking component 200 and a cover opening component 300; a first placement groove 101 for positioning the material box is formed in the positioning component 100; the unlocking component 200 is arranged on one side of the positioning component 100; the cover opening component 300 is arranged on one side of the positioning component 100, and the cover opening component 300 includes a first adsorption structure 310 and a first driving structure 320, the first adsorption structure 310 is used to adsorb the box cover, and the first driving structure 320 is connected to the first adsorption structure 310.

[0035] For example, Figure 1 and Figure 3As shown, the unlocking assembly 200 is arranged on the left side of the first placement slot 101, and the cover opening assembly 300 is arranged on the right side of the first placement slot 101. When the material box needs to be opened, the material box can be placed in the first placement slot 101. At this time, the movable end of the box cover is adjacent to the unlocking assembly 200, and the hinged end of the box cover is adjacent to the cover opening assembly 300; then, the unlocking assembly 200 can release the clamping between the movable end of the box cover and the side wall of the box body, and the first driving structure 320 can drive the first adsorption structure 310 to rotate leftward, so that the first adsorption structure 310 can approach and adsorb the box cover; then, under the drive of the first driving structure 320, the first adsorption structure 310 can drive the box cover to rotate rightward to complete the opening of the box cover.

[0036] It can be understood that after the material box is placed in the first placement slot 101, the box opening device of this embodiment can automatically open the material box without the need for staff to manually open the material box, thus saving time and effort.

[0037] Specifically, refer to Figure 4 The first adsorption structure 310 includes an adsorption plate 311 and a first adsorption head 312 . The first adsorption head 312 is disposed on the adsorption plate 311 , and the first adsorption head 312 is connected to a vacuum generating device.

[0038] Furthermore, when the first driving structure 320 drives the first adsorption structure 310 to rotate until the first adsorption head 312 is attached to the box cover, the first adsorption head 312 can adsorb the box cover.

[0039] Optionally, in some other embodiments of the present invention, the first adsorption structure 310 may also include an electromagnet. In this case, the box cover is made of a magnetic material or a magnetic attraction member is installed on the box cover.

[0040] It should be noted that if the rotation axis of the first adsorption structure 310 and the rotation axis of the box cover are on different lines, during the process of the first adsorption structure 310 adsorbing the box cover and driving the box cover to rotate, relative sliding is likely to occur between the first adsorption structure 310 and the box cover, thereby affecting the adsorption strength of the first adsorption structure 310 on the box cover.

[0041] Based on the above reasons, in some embodiments of the present invention, reference Figure 4 The first driving structure 320 includes a first driver 321 and a transmission member 322. The first driver 321 is connected to the transmission member 322 and is used to drive the transmission member 322 to rotate around a preset axis 301. The first adsorption structure 310 is connected to the transmission member 322 and is located on one side of the preset axis 301. The preset axis 301 is on the same straight line as the rotation axis of the box cover in the first placement groove 101.

[0042] It can be understood that when the material box is placed in the first placement groove 101, the rotation axis of the box cover of the material box can be located in the same straight line as the preset axis 301. At the same time, since the first driver 321 drives the first adsorption structure 310 to rotate around the preset axis 301 through the transmission member 322, the rotation axis of the first adsorption structure 310 can be coaxially arranged with the rotation axis of the box cover in the first placement groove 101, so as to reduce the probability of relative sliding between the first adsorption structure 310 and the transmission member 322 during the process of the first adsorption structure 310 driving the box cover to rotate.

[0043] It should be noted that, since the first placement groove 101 is formed in the positioning assembly 100, when the preset axis 301 and the rotation axis of the box cover in the first placement groove 101 are in the same straight line, the first adsorption structure 310 will interfere with the positioning assembly 100 during the rotation process.

[0044] Based on the above problems, in a further embodiment of the present invention, reference is made to Figure 4 The first driver 321 and the transmission member 322 are located on the same side of the first placement slot 101, and the first placement slot 101 is located on the extension path of the preset axis 301. The transmission member 322 includes a connecting portion 322a. On the projection plane perpendicular to the preset axis 301, the orthographic projection of the connecting portion 322a is located outside the orthographic projection of the positioning assembly 100, and the connecting portion 322a is connected to the first adsorption structure 310.

[0045] It can be understood that since the transmission member 322 includes a connecting portion 322a connected to the first adsorption structure 310, and on the projection plane perpendicular to the preset axis 301, the orthographic projection of the connecting portion 322a is located outside the orthographic projection of the positioning component 100, and thus, during the rotation of the first adsorption structure 310 around the preset axis 301, the first adsorption structure 310 can be staggered with the positioning component 100 to reduce the probability of interference between the first adsorption structure 310 and the positioning component 100.

[0046] For example, in Figure 4 In the embodiment, the first driver 321 and the transmission member 322 are both disposed at the lower side of the first placement groove 101, the preset axis 301 extends in the vertical direction, and the connecting portion 322a of the transmission member 322 extends directly below the positioning assembly 100 in the horizontal direction.

[0047] It should be noted that when the material box is placed in the first placement slot 101, the rotation axis of the box cover needs to be coaxially arranged with the preset axis 301. Therefore, the positioning component 100 needs to position the material box in the first placement slot 101 so that the rotation axis of the box cover is coaxially arranged with the preset axis 301, so as to facilitate the subsequent box opening component to open the box cover.

[0048] In order to realize the positioning of the magazine by the positioning assembly 100, in some embodiments of the present utility model, reference is made to Figure 1 and Figure 3 The positioning assembly 100 includes a second driving structure 110 and a plurality of positioning members 120. The plurality of positioning members 120 together define a first placement slot 101. The second driving structure 110 is connected to at least some of the positioning members 120, and can drive the positioning members 120 to approach each other to position the material box in the first placement slot 101, and make the rotation axis of the box cover and the preset axis 301 in the same straight line.

[0049] Specifically, the positioning assembly 100 includes three positioning members 120, which are respectively a first positioning member, a second positioning member and a third positioning member. The first positioning member and the second positioning member are respectively located on the left and right sides of the first placement groove 101, and the third positioning member is located on the rear side of the first placement groove 101. The second driving structure 110 includes a second driver and a third driver. The second driver is connected to the first positioning member, and the third driver is connected to the third positioning member. The second positioning member is fixedly arranged.

[0050] Furthermore, when the material box is placed in the first placement groove 101, the second driver drives the first positioning member to move to the right to cooperate with the second positioning member to position the material box in the left and right direction, and the third driver drives the third positioning member to push the material box forward to position the material box in the front and back direction, so that the rotation axis of the box cover can be coaxially arranged with the preset axis 301.

[0051] In order to better realize the positioning of the material box in the first placement slot 101, in a further embodiment of the present utility model, reference is made to Figure 2 A suction cup 103 is arranged at the bottom of the first placement groove 101 .

[0052] It is understandable that, when the material box is placed in the first placement groove 101, the suction cup 103 can absorb the bottom of the material box to limit and fix the material box, thereby facilitating the opening assembly 300 to open the cover of the material box.

[0053] It can be understood that in the process of the third driver driving the material box to move forward through the third positioning member, when the third driver reaches the stroke, the material box will continue to move forward for a certain distance due to inertia, thereby affecting the accuracy of positioning the material box in the front and rear directions; and by providing the suction cup 103, the suction cup 103 can hinder the movement of the material box relative to the bottom of the first placement groove 101, so that after the third driver reaches the stroke, the suction cup 103 can assist in braking the material box, so as to reduce the positioning error of the positioning assembly 100 on the material box.

[0054] refer to Figure 1 and Figure 2In some embodiments of the present invention, after the first positioning member, the second positioning member and the third positioning member cooperate with each other to define the first placement groove 101, an opening 101a is formed at the front end of the first placement groove 101, the unlocking component 200 is arranged on the left side of the opening 101a, and the first adsorption structure 310 is arranged on the right side of the opening 101a.

[0055] It can be understood that the material box can be placed in the first placement groove 101 with the box cover facing the opening 101a. At this time, the movable end of the box cover is located at the left end of the first placement groove 101, so that the unlocking component 200 can release the clamping between the movable end and the side wall of the box body. The movable end of the box cover is located at the right end of the first placement groove 101, and the rotation axis of the box cover is adjacent to the preset axis 301, so that the positioning component 100 can position the material box.

[0056] It can be understood that the setting of the opening 101a enables the first driving structure 320 to reduce the probability of interference between the box cover and / or the first adsorption structure 310 and the positioning assembly 100 when driving the first adsorption structure 310 to open or close the box cover, so that the box cover can be opened or closed smoothly.

[0057] It should be noted that an inner box is placed inside the material box. After the box opening assembly opens the box cover of the material box in the first placement slot 101, the inner box in the material box needs to be taken out to facilitate the subsequent handling device to grab the workpiece on the inner box.

[0058] In order to enable the box opening device of the present application to automatically take out the inner box from the material box, or automatically put the inner box into the material box, in some embodiments of the present invention, reference is made to Figure 1 The box opening device also includes a material transport component 500. The positioning component 100 is also formed with a second placement groove 102 connected to the opening 101a, and the second placement groove 102 is located in front of the first placement groove 101. The material transport component 500 is arranged on one side of the positioning component 100.

[0059] Furthermore, after the box opening component opens the box cover of the material box in the first placement slot 101, the material transport component 500 can transport the inner box of the material box in the first placement slot 101 to the second placement slot 102, so that the handling device can grab the material in the inner box; after the handling device has emptied the material in the inner box, the material transport component 500 can transport the inner box on the second placement slot 102 back into the box body of the first placement slot 101.

[0060] In a further embodiment of the present invention, reference Figure 1 and Figure 3The material transport assembly 500 includes a first pushing structure 510 and a second pushing structure 520; the first pushing structure 510 includes a fourth driver and a pushing rod, the fourth driver is connected to the pushing rod, the pushing rod passes through the third positioning member and extends into the first placement groove 101; the second pushing structure 520 includes a fifth driver 521, a pushing plate 522 and a slide rail 523, the fifth driver 521 and the slide rail 523 are both arranged on the left side of the first placement groove 101, and the fifth driver 521, the slide rail 523 and the first placement groove 101 are all located on the rear side of the pushing plate 522, the fifth driver 521 is connected to the left end of the pushing plate 522, the slide rail 523 extends in the front and rear direction, and the pushing plate 522 is slidably arranged on the slide rail 523.

[0061] It can be understood that a through hole is provided on the side wall of the box body opposite to the box mouth; when the inner box in the material box needs to be pushed into the second placement groove 102, the fourth driver can drive the pushing rod to move forward so that the pushing rod can pass through the through hole on the box body to push the inner box in the box body forward into the second placement groove 102; when the inner box in the second placement groove 102 needs to be pushed into the box body, the fifth driver 521 can drive the pushing plate 522 to move backward along the slide rail 523, so that the pushing plate 522 can push the inner box to move backward, so that the inner box is transferred from the second placement groove 102 to the box body of the first placement groove 101.

[0062] It can be understood that before the third driver drives the material box in the first placement slot 101 to move forward through the third positioning member, the fifth driver 521 can drive the push plate 522 to move backward to the opening 101a, and then the third driver can push the material box in the first placement slot 101 to move forward through the third positioning member; because the push plate 522 is located at the opening 101a at this time, the push plate 522 can cooperate with the third positioning member to position the material box in the first placement slot 101 in the front-to-back direction, thereby improving the accuracy of the positioning of the material box in the first placement slot 101 in the front-to-back direction.

[0063] It is understandable that by arranging the fifth driver 521 and the first placement slot 101 on the same side of the push plate 522, the size of the box opening device of this embodiment in the front-to-back direction can be reduced, so that the overall structure of the box opening device of this embodiment is more compact.

[0064] In some embodiments of the present invention, the unlocking component 200 includes a third driving structure and a cover-pushing component 210, the cover-pushing component 210 includes a hinged portion 211, a driving portion 212 and a cover-pushing portion 213, the driving portion 212 is connected to an end of the hinged portion 211 away from the first placement slot 101, the cover-pushing portion 213 is connected to an end of the hinged portion 211 close to the first placement slot 101, the hinged portion 211 is rotatably connected to the positioning component 100, the cover-pushing portion 213 can abut against the movable end of the box cover located in the first placement slot 101, and the third driving structure is connected to the driving portion 212.

[0065] It should be noted that the movable end of the box cover is provided with a snap-fitting protrusion, and the side wall of the box body is provided with a snap-fitting groove, and the snap-fitting protrusion is inserted into the snap-fitting groove to achieve snap-fitting between the movable end and the box body.

[0066] It can be understood that when the material box is positioned in the first placement groove 101, the box cover can be located in front of the cover-pushing part 213, and under the drive of the third driving structure, the driving part 212 can move backward. At this time, the cover-pushing part 213 can move forward to abut the movable end of the box cover, and push the movable end of the box cover forward to move away from the box body, thereby releasing the clamping connection between the box cover and the box body.

[0067] In some other embodiments of the utility model, the third driving structure is connected to the cover-pushing member 210 and is used to drive the cover-pushing member 210 to approach or move away from the first placement groove 101; in this case, the third driving structure can drive the cover-pushing member 210 to approach and squeeze the side wall of the box body in the first placement groove 101, so that the side wall of the box body is deformed, thereby causing the snap-fitting protrusion to disengage from the snap-fitting groove, thereby releasing the snap-fitting between the movable end and the box body.

[0068] It should be noted that when the inner box is installed in the material box, the gap between the inner box and the inner wall of the box body is small, and it is difficult for the material transport component 500 to push the inner box into or out of the box body.

[0069] Based on the above problems, in some embodiments of the present invention, reference Figure 1 The box opening device also includes a flaring component 400 , which is disposed on one side of the first placement groove 101 and is used to flare the box opening of the box body in the first placement groove 101 .

[0070] It can be understood that, by providing the expanding assembly 400, the expanding assembly 400 can expand the box opening of the box body to facilitate the inner box to enter or leave the box body.

[0071] refer to Figure 2In a specific embodiment of the utility model, the expansion assembly 400 includes a fourth driving structure 410, a second adsorption structure 420 and a third adsorption structure 430. The second adsorption structure 420 and the third adsorption structure 430 are respectively located on the left and right sides of the first placement groove 101. The fourth driving structure 410 is connected to the second adsorption structure 420 and is used to drive the second adsorption structure 420 to approach or move away from the third adsorption structure 430.

[0072] Furthermore, after the positioning component 100 positions the material box in the first placement slot 101, the left side wall of the material box is in close contact with the first positioning piece, and the right side wall of the material box is in close contact with the second positioning piece; then, the fourth driving structure 410 can drive the second adsorption structure 420 to approach the third adsorption structure 430, so that the second adsorption structure 420 can adsorb the left side wall of the material box, and the third adsorption structure 430 can adsorb the right side wall of the material box; then, the fourth driving structure 410 can drive the second adsorption structure 420 away from the third adsorption structure 430, so that the second adsorption structure 420 can cooperate with the third adsorption structure 430 to expand the material box.

[0073] Specifically, the second adsorption structure 420 includes a second adsorption head, and the third adsorption structure 430 includes a third adsorption head.

[0074] In order to improve the compactness of the box opening device of the present application, further, refer to Figure 2 The third adsorption structure 430 is embedded in the side wall of the second positioning member close to the first placement groove 101, and the first positioning member is provided with an avoidance gap for avoiding the second adsorption structure 420, and the second adsorption structure 420 is penetrated in the avoidance gap.

[0075] Optionally, in other embodiments of the present invention, the expansion assembly 400 also includes a fourth driving structure 410 and two extrusion members. In this case, the two extrusion members are respectively located on the upper and lower sides of the first placement groove 101, and the fourth driving structure 410 is respectively connected to the two extrusion members, and can drive the two extrusion members to approach each other to squeeze the upper and lower side walls of the box body, thereby achieving an increase in the size of the box mouth in the left and right directions.
