The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] In the description of the present invention, it should be understood that descriptions involving orientation, such as left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships 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 should not be understood as a limitation on the present invention.

[0026] In the description of the present invention, if there is a description of first and second, it is only 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.

[0027] 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.

[0028] refer to Figures 1 to 3The conveniently disassembled ceiling lamp of the embodiment of the present invention comprises: a base 100, including a material changing area 110 and an operation area 120; a guide mechanism 200, arranged at the end of the base 100, capable of guiding a box 700 into the material changing area 110; a plane positioning mechanism, arranged at the base 100, capable of plane positioning the box 700 entering the material changing area 110; a lifting mechanism 400, arranged at the base 100, capable of lifting the box 700 positioned by the plane positioning mechanism; a sliding transport mechanism, arranged at the base 100, and connected to the lifting mechanism 400; 00 is connected, and can drive the lifting mechanism 400 to move along the X direction to the working area 120 and the material changing area 110; wherein, the plane positioning mechanism includes an X-direction adjustment mechanism and a Y-direction adjustment mechanism, the X-direction adjustment mechanism includes an X-direction pushing device 310 and a limit plate 320, the limit plate 320 is arranged on the sliding transport mechanism and can move synchronously with the lifting mechanism 400, the X-direction pushing device 310 can push the box body 700 entering the material changing area 110 to abut against the limit plate 320, and the Y-direction adjustment mechanism can push the box body 700 to a set position along the Y direction.

[0029] Under the guidance of the guide mechanism 200, the box 700 is pushed into the material changing area 110. At this time, the personnel evacuate and the device starts to operate automatically. The X-direction pushing device 310 pushes the box 700 to abut against the limit plate 320. The Y-direction adjustment mechanism pushes the box 700 to the set position along the Y direction. At this time, the box 700 is in the working position of the lifting mechanism 400. The lifting mechanism 400 lifts the box 700. Driven by the sliding transport mechanism, the lifting mechanism 400 moves the box 700 from the material changing area 110 to the working area 120 along the X direction. After the workstation operation is completed, the lifting mechanism 400 moves the box 700 from the working area 120 to the material changing area 110 along the X direction. The limit plate 320 moves synchronously with the lifting mechanism 400, which improves the positioning accuracy. That is, the position of the lifting mechanism 400 is the positioning reference. When the sliding transport mechanism has problems such as aging that cause the lifting mechanism 400 to have a position deviation in the X direction, the X-direction pushing device 310 can also be used to push the box 700 to abut against the limit plate 320, and the positioning accuracy can still be guaranteed.

[0030] It is conceivable that, in some embodiments of the present invention, the limiting plate 320 is fixedly disposed on the base 100 and does not move synchronously with the lifting mechanism 400 .

[0031] It is understandable that in some embodiments of the present invention, the limiting plate 320 can also be changed to an X-direction pushing device 310, that is, the X-direction pushing device 310 is relatively arranged along the X-direction, and the X-direction positioning of the box 700 can also be achieved.

[0032] In certain embodiments, reference Figures 1 to 3The Y-direction adjustment mechanism includes Y-direction pushing units 330 arranged on the left and right sides of the base 100. The Y-direction pushing units 330 on the left and right sides are relatively arranged. Under the pushing action of the Y-direction pushing units 330, the positioning of the box 700 along the Y-direction can be achieved.

[0033] Specifically, in some embodiments of the present invention, the Y-axis pushing unit 330 is a Y-axis pushing cylinder, and the end of the telescopic rod of the Y-axis pushing cylinder is connected to a pushing plate. The pushing plates of the Y-axis pushing cylinders on the left and right sides are relatively arranged. When the position of the box body 700 is biased to the left, the pushing plate of the Y-axis pushing cylinder on the left pushes the box body 700 to the set position. Conversely, when the position of the box body 700 is biased to the right, the Y-axis pushing cylinder on the right also acts.

[0034] In some embodiments of the present invention, four Y-axis pushing units 330 are provided, which are arranged in groups of two on the left and right sides of the base 100, and the two Y-axis pushing units 330 on each side are arranged at intervals. Four Y-axis pushing units 330 are used to push the box body 700 at the same time, which better ensures the positioning accuracy and saves time.

[0035] It is conceivable that, in some embodiments of the present invention, the Y-axis pushing unit 330 may also be a hydraulic cylinder, an electric cylinder, etc., as long as it can push the box body 700.

[0036] It is understandable that in some embodiments of the present invention, the Y-axis pushing units 330 are set to 2, 3, 5, 6 or more, and the purpose of Y-axis positioning of the box 700 can be met by changing the position of the Y-axis pushing units 330.

[0037] In certain embodiments, reference Figure 2 and Figure 3 The sliding transport mechanism includes a connecting plate 510, a slider 520, a slide rail 530 and a mobile driving unit. The lifting mechanism 400 is fixedly connected to the connecting plate 510, the connecting plate 510 is connected to the slider 520, the slider 520 and the slide rail 530 are slidably matched, the mobile driving unit can drive the slider 520 to slide along the slide rail 530, and the limit plate 320 is arranged on the connecting plate 510. The limit plate 320 moves synchronously with the connecting plate 510, which improves the positioning accuracy, that is, the position of the connecting plate 510 is the positioning reference. When the sliding transport mechanism has problems such as aging, which causes the connecting plate 510 to have a position deviation in the X direction, the X-direction pushing device 310 can also be used to push the box 700 to abut against the limit plate 320, and the positioning accuracy in the X direction can still be guaranteed.

[0038] Specifically, in some embodiments of the present invention, four lifting mechanisms 400 are provided, which are arranged in groups of two on the left and right sides of the machine base 100, and the connecting plate 510 is provided in a U-shape, with one connecting plate 510 on each of the left and right sides of the machine base 100, and one lifting mechanism 400 is connected to the left and right sides of the U-shaped connecting plate 510, respectively, and two sliding blocks 520 are connected to the bottom of each U-shaped connecting plate 510, and the sliding rails 530 are provided in two numbers, which are respectively arranged on the left and right sides of the machine base 100, along the machine base 100. The seat 100 extends in the front-to-back direction (X direction), the slider 520 is engaged with the slide rail 530 and can slide along the slide rail 530. When the box 700 is positioned by the planar positioning mechanism, the four corner points of the box 700 correspond to the four lifting mechanisms 400. The four lifting mechanisms 400 can lift the box 700 smoothly and drive the box 700 to move from the material changing area 110 to the working area 120. After the operation is completed, the lifting mechanism 400 drives the box 700 back to the material changing area 110.

[0039] It is conceivable that in some embodiments of the present invention, six lifting mechanisms 400 are provided, with three of them being arranged in a group on the left and right sides of the base 100 , and the shape of the connecting plate 510 and the number of the sliders 520 can be changed accordingly.

[0040] It is understandable that in some embodiments of the present invention, the number of lifting mechanisms 400 and sliders 520 can be increased or decreased, and the box body 700 can be lifted stably by changing the position of the lifting mechanism 400 corresponding to the box body 700.

[0041] In certain embodiments, reference Figure 3 and Figure 6 The lifting mechanism 400 includes a Z-direction lifting unit 410 arranged on the connecting plate 510, the Z-direction lifting unit 410 is provided with a loading platform 420, the loading platform 420 is provided with a locking pin 430, the loading platform 420 and the locking pin 430 can move up and down driven by the Z-direction lifting unit 410, the locking pin 430 can be inserted into the reserved positioning hole 710 of the box body 700, the loading platform 420 carries the box body 700, and the locking pin 430 can ensure that the lifting mechanism 400 drives the box body 700 to move, and the box body 700 does not shift in position.

[0042] Specifically, in some embodiments of the present invention, the Z-axis lifting unit 410 is a Z-axis lifting cylinder, the end of the telescopic rod of the Z-axis lifting cylinder is connected to the worktable 420, thereby driving the worktable 420 to move up and down, and the lower end of the locking pin 430 is connected to the worktable 420, and the upper end of the locking pin 430 is conical, which plays a guiding role, making it easier to insert the locking pin 430 into the reserved positioning hole 710 of the box 700.

[0043] It is conceivable that, in some embodiments of the present invention, the Z-direction lifting unit 410 may also be a hydraulic cylinder, an electric cylinder, etc., as long as it can lift the box body 700.

[0044] In certain embodiments, reference Figures 1 to 4 The mobile driving unit includes a belt 540, a driven wheel 550, a driving wheel 560, and a driving device 570 connected to the driving wheel 560. The driving device 570 and the driving wheel 560 are arranged at one end of the base 100, and the driven wheel 550 is arranged at the other end of the base 100. The driving wheel 560 and the driven wheel 550 are connected by a belt 540, and the belt 540 is fixedly connected to the connecting plate 510. The driving device 570 drives the driving wheel 560 to rotate, and the driving wheel 560 drives the belt 540 and the driven wheel 550 to rotate, and the belt 540 drives the connecting plate 510 to change its position.

[0045] Specifically, in some embodiments of the present invention, the belt 540, the driven wheel 550, and the driving wheel 560 are each configured in two. The two driving wheels 560 are respectively arranged on the left and right sides of the machine base 100. The two driving wheels 560 are connected by a connecting rod and rotate under the drive of the driving device 570. Each driving wheel 560 drives one belt 540 and one driven wheel 550 to rotate. Each belt 540 is connected to a connecting plate 510. The rotational motion of the belt 540 is converted into the translational motion of the connecting plate 510. The translational direction of the connecting plate 510 can be changed by changing the rotation direction of the driving wheel 560, so that the connecting plate 510 can move between the material changing area 110 and the working area 120.

[0046] It is conceivable that in some embodiments of the present invention, the sliding transport mechanism is a screw transmission mechanism, the slide rail 530 is a threaded rod, the slider 520 has an internal thread that cooperates with the threaded rod, and the threaded rod is driven to rotate by the driving device 570, so that the slider 520 can drive the connecting plate 510 to move along the slide rail 530.

[0047] In certain embodiments, reference Figure 1 and Figure 2 The guide mechanism 200 includes guide wheels 210, which are arranged on the left and right sides of the base 100, and the distance between the guide wheels 210 on the left and right sides of the base 100 gradually decreases along the feeding direction of the box body 700. The guide wheels 210 can guide the box body 700 to enter the material replacement area 110.

[0048] Specifically, in some embodiments of the present invention, the guide wheels 210 are provided in number of 12, which are arranged in pairs on the left and right sides of the machine base 100; the six guide wheels 210 located in the middle of the material changing area 110 have a fixed spacing and are arranged in parallel on the left and right sides; the six guide wheels 210 located at the ends of the machine base 100 are arranged in an "eight" shape, with the large end facing outward and the small end facing inward, thereby guiding the box 700 to enter the material changing area 110.

[0049] It is conceivable that, in some embodiments of the present invention, the number of guide wheels 210 can be dynamically increased or decreased according to the size of the box 700 to meet the needs of guiding the box 700.

[0050] In certain embodiments, reference Figure 1 and Figure 2 The guide mechanism 200 further includes a wheel shaft 220 and an adjustment slot 230 disposed on the base 100, wherein the adjustment slot 230 extends along the Y direction, and the guide wheel 210 is rotatably disposed on the wheel shaft 220, and the end of the wheel shaft 220 is adjustably disposed in the adjustment slot 230. The position of the end of the wheel shaft 220 on the adjustment slot 230 can be dynamically adjusted, thereby further changing the position of the guide wheel 210 connected to the wheel shaft 220.

[0051] Specifically, in some embodiments of the present invention, the adjustment groove 230 is arranged along the left and right direction (Y direction) of the base 100. By adjusting the position of the end of the axle 220 in the adjustment groove 230, the position of the guide wheel 210 connected to the axle 220 is further changed, and the distance between the guide wheels 210 opposite to each other on the left and right sides of the base 100 can be changed to adapt to boxes 700 of different sizes.

[0052] It is conceivable that in some embodiments of the present invention, each adjustment slot 230 is a group of adjustment holes. By placing the wheel axle 220 in different adjustment holes, the distance between the guide wheels 210 disposed opposite to each other on the left and right sides of the base 100 can also be changed.

[0053] In certain embodiments, reference Figure 1 , Figure 2 and Figure 5, an in-and-out channel for guiding the box 700 to enter or exit the material changing area 110 is formed between the guide mechanism 200 and the end of the machine base 100, and the X-direction pushing device 310 is located below the in-and-out channel, and the X-direction pushing device 310 includes a flip arm 311 and an abutting wheel 312 arranged at the end of the flip arm 311, and the flip arm 311 has a first working position and a second working position, when the flip arm 311 is in the first working position, the abutting wheel 312 is located in the in-and-out channel and abuts against the end of the box 700, when the flip arm 311 is in the second working position, the abutting wheel 312 is separated from the end of the box 700, and the abutting wheel 312 is located below the in-and-out channel. When the flip arm 311 is in the second working position, the abutting wheel 312 is located below the in-and-out channel, ensuring that the X-direction pushing device 310 will not affect the box 700 entering and exiting the material changing area 110 through the in-and-out channel.

[0054] Specifically, in some embodiments of the present invention, the X-axis pushing device 310 is set to two groups, which are respectively arranged on the left and right sides of the machine base 100. When the box body 700 enters or exits the material changing area 110 through the entry and exit channel under the guidance of the guide mechanism 200, the flip arm 311 is in the second working position, ensuring that the X-axis pushing device 310 will not affect the box body 700 entering or exiting the material changing area 110. After the box body 700 enters the material changing area 110, the flip arm 311 flips to the first working position, and the abutment wheel 312 pushes the box body 700 so that it abuts against the limit plate 320.

[0055] It is conceivable that, in some embodiments of the present invention, the X-axis pushing device 310 is arranged below the entry and exit channel, that is, below the box body 700 of the material changing area 110, and the flip arm 311 flips from bottom to top; the X-axis pushing device 310 can also be arranged on both sides of the entry and exit channel, that is, on both sides of the box body 700 of the material changing area 110, and the flip arm 311 flips from the left and right sides to the middle.

[0056] In certain embodiments, reference Figure 5 The X-direction pushing device 310 further includes an X-direction driving unit 313 and an output shaft 314 that can be driven to rotate by the X-direction driving unit 313. One end of the flip arm 311 away from the abutting wheel 312 is connected to the output shaft 314. Driven by the output shaft 314, the flip arm 311 can flip and switch between the first working position and the second working position to achieve the abutting wheel 312 abutting against the box body 700 or separating from the box body 700.

[0057] Specifically, in some embodiments of the present invention, the X-axis driving unit 313 is a swing cylinder. Under the action of pneumatic force, the output shaft 314 can rotate to a certain angle to drive the flip arm 311 to perform a flipping motion.

[0058] It is conceivable that, in some embodiments of the present invention, the X-axis driving unit 313 is a swing hydraulic cylinder, a servo motor or a stepping motor, which can realize the quantitative rotation movement of the output shaft 314, thereby driving the flip arm 311 to flip.

[0059] In certain embodiments, reference Figure 1 and Figure 6 , and also includes a turnover trolley 600, which includes a frame 610 and a moving wheel set 620 arranged at the bottom of the frame 610. The box 700 can be placed on the frame 610, and the box 700 enters or exits the material change area 110 under the drive of the turnover trolley 600.

[0060] Specifically, in some embodiments of the present invention, the turnover trolley 600 drives the box 700 through the guide mechanism 200. Under the guiding action of the guide mechanism 200, the box 700 and the turnover trolley 600 are guided into the material replacement area 110. Then the plane positioning mechanism performs plane pushing positioning on the box 700. Due to the presence of the moving wheel group 620 of the turnover trolley 600, the horizontal movement of the box 700 will not be hindered. After the plane positioning mechanism completes the positioning, the lifting mechanism 400 lifts the box 700 and moves it to the working area 120. When the lifting mechanism 400 contacts the box 700, the plane positioning mechanism will retreat to the initial position to avoid the force of the plane positioning mechanism on the box 700 affecting the operation of the lifting mechanism 400. After the operation is completed, the lifting mechanism 400 lifts the box 700 back to the material replacement area 110, and makes the box 700 fall onto the turnover trolley 600, so that the turnover trolley 600 can be pulled out of the material replacement area 110.

[0061] It is conceivable that, in some embodiments of the present invention, the turnover vehicle 600 is an automatic tracking robot, which can further increase the degree of automation.

[0062] In some embodiments of the present invention, the above-mentioned entry and exit channel for guiding the box 700 to enter or exit the material changing area 110 is formed between the plane where the upper end surface of the turnover trolley 600 is located and the guide mechanisms 200 on both sides, and the X-axis pushing device 310 is located below the entry and exit channel, that is, below the plane where the upper end surface of the turnover trolley 600 is located.

[0063] Specifically, the width of the turnover trolley 600 is smaller than the width of the box 700 placed on the turnover trolley 600. When the box 700 enters or exits the material changing area 110 through the above-mentioned entry and exit channel, the turnover trolley 600 passes through the middle of the X-axis pushing device 310 located on the left and right sides of the machine base 100, and the box 700 passes through the upper part of the X-axis pushing device 310.
