DETAILED DESCRIPTION

[0031] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0032] The present application discloses a material 5 turning device, such as Figures 1 to 3 As shown, the material 5 turning device mainly includes three parts, namely a supporting mechanism 1, a material 5 clamping mechanism 2 and a guiding mechanism 3; the supporting mechanism 1 is arranged at the bottom of the entire turning device to play a supporting role, and the material 5 clamping mechanism 2 is installed at the upper end of the supporting mechanism 1, and the guiding mechanism 3 is arranged between the material 5 clamping mechanism 2 and the supporting mechanism 1, and the material 5 clamping mechanism 2 and the supporting mechanism 1 are movably connected by relying on the guiding mechanism 3, and the guiding direction of the guiding mechanism 3 is arc-shaped, and the material 5 clamping mechanism 2 is located on the inner arc side of the arc-shaped guiding direction of the guiding mechanism 3, and the supporting mechanism 1 is located on the outer arc side of the arc-shaped guiding direction of the guiding mechanism 3, so that the material 5 clamping mechanism 2 can rely on the guiding mechanism 3 to slide in an arc, so that the material 5 placed thereon can be turned over, and setting different lengths of the guiding mechanism 3 can control the change of the turning angle of the guiding mechanism 3, which can meet the requirement of 90° turning of the material 5.

[0033] Each component will be introduced below; first, the supporting mechanism 1 mainly includes a supporting base 11, which is a rectangular body surrounded by multiple plates, and an arc-shaped guide groove 31 is opened above the supporting base 11. The guide groove 31 is used to accommodate and support the material 5 clamping mechanism 2, and can also serve as a rotation path for the material 5 clamping mechanism 2.

[0034] In addition, an angle adjustment mechanism is provided at the bottom of the support base 11, and the angle adjustment mechanism can adjust the horizontal state of the support base 11 to keep the whole device stable.

[0035] The angle adjustment mechanism includes at least one height adjustment structure 13, and the height adjustment structure 13 includes: a first fixing plate 131, a second fixing plate 132 and an adjustment bolt 133. The first fixing plate 131 and the lower end of the support base 11 are welded and fixed, and two threaded holes are also provided on the first fixing plate 131, and the adjustment bolt 133 is screwed into the threaded hole from the top of the first fixing plate 131, and the second fixing plate 132 is arranged below the first fixing plate 131, and the lower end of the adjustment bolt 133 is rotatably clamped on the second fixing plate 132, and the second fixing plate 132 is tightened on the ground by the fixing bolt 134; when adjustment is needed, it is only necessary to rotate the adjustment bolt 133 to change the distance between the first fixing plate 131 and the second fixing plate 132, thereby adjusting the height of the support base 11 and the ground, and a set of height adjustment structures 13 is provided at each of the four corners of the bottom of the support base 11, so that the horizontal state of the flip device can be well adjusted to keep it horizontal, so as to avoid the risk of the material 5 falling off due to the unstable placement when placing the material 5.

[0036] Furthermore, the material 5 clamping mechanism 2 is installed above the support base 11, specifically in the guide groove 31. The material 5 clamping mechanism 2 has a main body 21. The main body 21 of the material 5 clamping mechanism 2 is directly installed and placed in the guide groove 31, and the bottom surface of the main body 21 is consistent with the shape of the guide groove 31. The material 5 clamping mechanism 2 includes a placement groove 22 and a clamping structure 23 arranged on the main body 21.

[0037] The placement groove 22 is opened on the main body 21, and the shape of the placement groove 22 is V-shaped, that is, the size of the placement groove 22 gradually increases from the bottom of the groove to the opening, so that the material 5 can be placed from the groove opening; when the placed material 5 is an aluminum foil heat sink of an air conditioner, based on the shape of the material 5, the groove walls on both sides of the placement groove 22 are set to be perpendicular to each other (the angle between the two groove walls of the V-shaped placement groove 22 is set to 90°), and the stacked aluminum foil heat sinks are placed in the placement groove 22, and then the clamping structure 23 is used to clamp these aluminum foil heat sinks to prevent them from slipping out of the placement groove 22.

[0038] The clamping structure 23 moves relative to the placement slot 22 to clamp the material 5. Figure 4 , 5 As shown, the clamping structure 23 specifically includes: a driving device 230 and a clamping piece 235, wherein the driving device 230 is installed and fixed on the main body 21, wherein the driving device 230 is a three-rod cylinder.

[0039] Specifically, a cylinder mounting plate 231 is further provided on the main body 21, and the three-rod cylinder is mounted and fixed on the cylinder mounting plate 231. A hinge seat 232 is provided on the telescopic end of the three-rod cylinder, and a connecting rod limiting latch 233 is provided on the hinge seat 232. One end of the connecting rod 234 is hinged and fixed to the hinge seat 232 through the connecting rod limiting latch 233, and the other end of the connecting rod 234 away from the cylinder is hinged and fixed to the clip 235 through the connecting seat 236 on the clip 235. The clip 235 is located at the notch of the placement groove 22 and is opposite to any one of the groove walls of the placement groove 22; a guide rod 234 is also provided on the main body 21. 37, the guide rod 237 is fixed to the main body 21 through the guide rod 237 connecting seat 236, and the guide rod 237 and the connecting rod 234 are cross-arranged, the guide rod 237 and the connecting rod 234 are in a vertical state, and the guide rod 237 is arranged between the clamping piece 235 and the cylinder, and the guide rod 237 and the connecting rod 234 are rotatably connected, so that the guide rod 237 acts as a fulcrum. Under the push of the three-rod cylinder, one end of the connecting rod 234 is lifted up, and the clamping piece 235 on the other end is close to the groove wall of the placement groove 22, so that the material 5 is tightly attached to the placement groove 22 and will not be scattered.

[0040] Preferably, the clip 235 is made of an aluminum alloy plate to ensure that it has good structural strength.

[0041] Furthermore, a through hole 239 with a length is provided on the guide rod 237, and the length direction of the through hole 239 is perpendicular to the axial direction of the guide rod 237 and the connecting rod 234. The connecting rod 234 is inserted into the through hole 239, so that the connecting rod 234 can slide up and down in the through hole 239, giving the connecting rod 234 a certain margin when it moves, so that when the clamp 235 clamps the material 5, the connecting rod 234 can move upward appropriately, allowing the clamp 235 to undergo a certain deformation but not to break due to excessive deformation. At the same time, when taking out the material 5, the connecting rod 234 can be lifted to keep the clamp 235 away from the material 5 to avoid interference with the clamp 235.

[0042] Furthermore, the guide mechanism 3 includes three parts, namely the guide groove 31 mentioned above, a guide rail 32 provided on the material 5 clamping mechanism 2, and a limiting structure 33 for limiting the relative position of the guide rail 32 and the guide groove 31.

[0043] The structure of the guide groove 31 has been explained above and will not be repeated here; the guide rail 32 is installed at the bottom of the main body 21 of the material 5 clamping mechanism 2, and the guide rail 32 is also curved in an arc shape to match the guide groove 31. The guide rail 32 is directly installed on the guide groove 31, and the two cooperate with each other. The guide rail 32 slides in the guide groove 31, thereby driving the material 5 clamping mechanism 2 to rotate and flip.

[0044] Preferably, the cross section of the guide rail 32 is an inverted T-shape, and two guide rails 32 are arranged in parallel at the bottom of the support base 11 , and the guide rails 32 can slide in the guide groove 31 .

[0045] The limiting structure 33 mainly includes a limiting member 331. Each guide rail 32 is provided with a pair of limiting members 331. The limiting members 331 are symmetrically arranged at the two end positions of the guide groove 31 to ensure that the force on the guide rail 32 is uniform and the limiting effect is optimal. A mounting frame 332 is provided on the support base 11, and the limiting member 331 is installed on the mounting frame 332. The limiting member 331 is arranged on the upper end surface of the guide rail 32, that is, on the side of the guide rail 32 relative to the guide groove 31, wherein the limiting member 331 is in the form of a first roller, so that when the guide rail 32 is sliding, the limiting member 331 can play a supporting and limiting role; in other embodiments, the limiting member 331 can also be set in the form of a sphere with a smooth and round surface, as long as it can play a limiting role. Of course, it is relatively better to set it as a first roller, which can not only play a limiting role on the guide rail 32, but also reduce the friction between the two.

[0046] Combined with Figure 3 , 6 As shown, in addition to the limit member 331, the present application also provides a guide member 34 between the guide groove 31 and the guide rail 32. Different from the form of direct sliding connection between the guide rail 32 and the guide groove 31, the guide member 34 is provided between the guide groove 31 and the guide rail 32. The guide member 34 can well reduce the friction between the two; wherein, the support base 11 in the present application is a hollow structure composed of a plate body, and the upper end of the support base 11 has no top, so the guide member 34 is to be installed by relying on a mounting shaft 35 mounted inside the support base 11. The guide member 34 is installed on the mounting shaft 35 to directly support the guide rail 32. Similarly, each guide rail 32 corresponds to at least two guide members 34. The guide member 34 adopts the form of a second roller, and realizes the guiding effect on the guide rail 32 by rotation, and also reduces the sliding resistance between the guide groove 31 and the guide rail 32.

[0047] Preferably, the first roller and the second roller are also provided with bearings, which can further reduce the friction resistance.

[0048] Furthermore, the material 5 turning device in the present application has, in addition to the above-mentioned supporting mechanism 1, material 5 clamping mechanism 2 and guiding mechanism 3, a driving mechanism 4. The setting of the driving mechanism 4 can drive the material 5 clamping mechanism 2 to automatically turn over, thereby achieving the effect of saving manpower.

[0049] Among them, in this embodiment, if Figure 6As shown, the driving mechanism 4 mainly includes three parts: a driving motor 41, a screw rod 42 and a straight rod 43. The driving motor 41 is installed inside the supporting base 11. The output shaft of the driving motor 41 is fixedly connected to the screw rod 42 through a coupling 44. Since the screw rod 42 is relatively long, two support seats 45 (the number can be arbitrary) are required to be arranged in the axial direction of the screw rod 42. The screw rod 42 passes through the support seats 45 and is supported by the support seats 45. At the same time, in order to reduce the friction between the support seats 45 and the screw rod 42, a ball bearing is also sleeved on the screw rod 42, so that the screw rod 42 can rotate stably; the straight rod 43 is arranged on the material 5 clamping mechanism 2, which has The body is connected between two inverted T-shaped guide rails 32, and the number of straight rods 43 is set to be several, and the several straight rods 43 are spaced and evenly arranged in a circle in the guide direction of the material 5 clamping mechanism 2. After the material 5 clamping mechanism 2 and the support mechanism 1 are installed, the lowest end of the circle on which the straight rods 43 are arranged is tangent to the spiral rod 42, and the spiral rod 42 is provided with a spiral blade, which is inserted into the interval between the straight rods 43 and the straight rods 43. When the spiral rod 42 rotates, the straight rod 43 can be pushed to rotate in the guide direction under the action of the spiral blade, thereby driving the material 5 clamping mechanism 2 to rotate, and the limit member 331 limits the material 5 clamping mechanism 2 within a fixed track, thereby realizing the flipping of the material 5.

[0050] Preferably, the driving motor 41 is a DC brake reduction motor, so as to better control the rotation and stop of the material 5 clamping mechanism 2.

[0051] The above specific embodiments are only used to illustrate the concept of the present invention. A person skilled in the art may make various modifications and changes based on the concept of the present invention, and these modifications and changes are all included in the protection scope of the present invention.
