[0041] After the hot pressing of the plate in the hot press is completed, the plate unloader is sent into the hot press so that the suction cup is located above the plate. Then the driving component drives the adsorption component to move downward, the suction cup adsorbs the plate, and then the plate unloader moves the plate out of the hot press to complete the unloading.

[0042] During the process of the adsorption rack adsorbing the plate, due to the high internal temperature of the hot press, the adsorption rack will expand due to the heat, causing the adsorption rack to become longer on both sides in the length direction, which can easily cause the adsorption rack to deform and cause damage.

[0043] An embodiment of the utility model provides a plate unloading machine 100, in which an adjustment component 40 is arranged between a bracket 10 and an adsorption frame 21. The adjustment component 40 is arranged to be pushed and extended by the adsorption frame 21 after the adsorption frame 21 enters the interior of a hot press and undergoes thermal expansion, so that the adsorption frame 21 can move outward in a horizontal direction, and the deformation amount of the adsorption frame 21 can be adjusted to avoid deformation and damage of the adsorption frame 21, thereby improving the structural stability of the plate unloading machine 100.

[0044] Figure 1 is a schematic structural diagram of a plate unloading machine 100 according to an embodiment of the utility model. Figure 2 yes Figure 1 A schematic top view of the plate unloader 100 is shown. Figure 3 yes Figure 2 A schematic enlarged view of the middle part, Figure 4 yes Figure 1 Schematic diagram of the structure of the adjustment component 40. Figures 1-4 As shown, the plate unloading machine 100 of the embodiment of the utility model can generally include a bracket 10 and an adsorption component 20, at least one driving component 30 and at least one adjusting component 40. Among them, the adsorption component 20 includes an adsorption frame 21 and at least one suction cup 22 installed on the adsorption frame 21, and the adsorption frame 21 is movably connected to the bracket 10. The driving component 30 is arranged on the bracket 10 and connected to the adsorption frame 21, and is used to drive the adsorption component 20 to move to the inside of the hot press to adsorb the plate after hot pressing. The adjusting component 40 is arranged on the side of the length direction of the adsorption frame 21, and each adjusting component 40 is respectively connected to the adsorption frame 21 and the bracket 10. The adjusting component 40 is arranged to be retractable along the length direction of the adsorption frame 21, so that after the adsorption frame 21 enters the inside of the hot press and undergoes thermal expansion, it is pushed and extended by the adsorption frame 21, so that the adsorption frame 21 moves outward.

[0045] Here, it can be understood that the adsorption rack 21 is located above the bracket 10, and the suction cup 22 is installed on the adsorption rack 21 to adsorb the plate located below the adsorption rack 21. The bracket 10 is used to support the adsorption assembly 20, the drive assembly 30 and the adjustment assembly 40. The drive assembly 30 can drive the adsorption assembly 20 to move vertically up and down. After the unloader 100 is moved to the top of the plate, the drive assembly 30 is operated to drive the adsorption assembly 20 to move downward to the inside of the hot press. After the suction cup 22 adsorbs the plate, it drives the plate to move upward, thereby removing the plate inside the hot press.

[0046] The adsorption rack 21 is connected to the bracket 10 through the adjustment component 40, and the adjustment component 40 is retractable along the length direction of the adsorption rack 21, so that the unloader 100 can adapt to the expansion length of the adsorption rack 21, and the adsorption rack 21 will not collide with the bracket 10 after thermal expansion, causing the adsorption rack 21 to shake or even be damaged. It can be understood that the elongation of the adjustment component 40 is the expansion elongation of the adsorption rack 21.

[0047] In the embodiment of the utility model, an adjustment component 40 is set between the adsorption frame 21 and the bracket 10. When the adsorption frame 21 enters the interior of the hot press to adsorb the plate, the adsorption frame 21 can push the adjustment component 40 to extend toward the outside of the adsorption frame 21, so that the adsorption frame 21 can move outward in the horizontal direction, and the deformation amount of the unloading machine 100 can be adjusted to avoid deformation and damage of the adsorption frame 21, thereby improving the structural stability of the unloading machine 100.

[0048] In one embodiment, see Figure 2 , the number of the suction cups 22 is set to 8. In other embodiments, the number of the suction cups 22 can be set according to actual needs, for example, it can be 1, 2, 3, 4, or 5.

[0049] In some embodiments, the bracket 10 includes at least one first column 11 arranged vertically, and the plate unloader 100 also includes at least one guide assembly 50, which is vertically installed on the first column 11 and connected to the adsorption frame 21 and the adjustment assembly 40. The guide assembly 50 is configured to guide the adsorption frame 21 during the movement of the adsorption frame 21.

[0050] The first column 11 is arranged vertically, so that the adsorption rack 21 can move stably when moving vertically. The guide design can prevent the adsorption rack 21 from deflecting or shaking during the vertical movement, so that the plate unloader 100 can move the plate stably. The first column 11 can also bear the weight of the adsorption rack 21, so that the structure of the plate unloader 100 remains stable.

[0051] In this embodiment, the number of the first columns 11 is two, and the two first columns 11 are respectively located on both sides of the length direction of the adsorption frame 21. In other embodiments, the number of the first columns 11 can be set according to actual needs.

[0052] In some embodiments, each adjustment assembly 40 includes a first slide rail 41 and a first slider 42. The first slide rail 41 is connected to the bracket 10 and arranged along the length direction of the adsorption frame 21. The first slider 42 is slidably connected to the first slide rail 41 and connected to the adsorption frame 21. The first slider 42 is configured to slide toward the outside of the adsorption frame 21 after the adsorption frame 21 undergoes thermal expansion, thereby driving the adsorption frame 21 to move outward.

[0053] See also Figure 3 The adsorption rack 21 has a connection portion formed by protruding outward along the length direction, and the side of the connection portion along the width direction of the adsorption rack 21 is fixedly connected to the first slider 42. The first slider 42 is fixedly connected to the adsorption rack 21, and the first slide rail 41 and the first slider 42 are interlocked with each other, so that when the adsorption rack 21 moves vertically up and down, the adsorption rack 21 can drive the first slider 42 to move vertically up and down, and then drive the first slide rail 41 to move vertically up and down.

[0054] The first slide rail 41 is slidably connected to the first column 11 . When the first slide rail 41 moves vertically, the guide assembly 50 guides the adjustment assembly 40 and the adsorption rack 21 , so that the adsorption rack 21 can move stably.

[0055] When the adsorption frame 21 enters the hot press to adsorb the plate, the adsorption frame 21 expands due to the heat. Since a first slider 42 is provided between the bracket 10 and the adsorption frame 21, the first slider 42 can slide toward the outside of the adsorption frame 21 under the action of the expansion force of the adsorption frame 21, so that the adsorption frame 21 can move in a horizontal direction relative to the bracket 10, and the deformation amount of the adsorption frame 21 can be adjusted to avoid deformation and damage of the adsorption frame 21, thereby improving the structural stability of the plate unloading machine 100 and extending the service life of the plate unloading machine 100.

[0056] In some embodiments, the adjustment component 40 may be other telescopic components, such as a telescopic rod.

[0057] In some embodiments, each guide assembly 50 includes a second slide rail 51 and a second slider 52. The second slide rail 51 is connected to the first column 11 and arranged vertically. The second slider 52 is slidably connected to the second slide rail 51 and connected to the adsorption frame 21. The second slider 52 is connected to the second slide rail 51.

[0058] Here, the second slide rail 51 is fixedly connected to the first column 11. The second slider 52 is fixedly connected to the adjustment assembly 40, and can move vertically up and down relative to the second slide rail 51. The adsorption assembly 20 moves vertically up and down under the action of the driving assembly 30, thereby driving the second slider 52 to slide relative to the second slide rail 51.

[0059] The second slide rail 51 and the second slider 52 cooperate with each other to guide the adjustment component 40 and the adsorption component 20, thereby improving the movement accuracy and movement stability of the plate unloader 100.

[0060] In some embodiments, there are two adjustment components 40, and the two adjustment components 40 are respectively arranged on both sides of the length direction of the adsorption frame 21. In this way, an adjustment component 40 is correspondingly arranged on both sides of the adsorption component 20, and the adsorption frame 21 can move along both sides of the length direction of the adsorption frame 21 after thermal expansion, which can improve the reliability of the adjustment component 40.

[0061] In some embodiments, the two adjustment components 40 are arranged in alignment, that is, the two adjustment components 40 are arranged in corresponding positions in the length direction of the adsorption rack 21, so that the adsorption rack 21 can be evenly stressed in the length direction when it expands due to heat, and the structural stability of the unloader 100 can be improved. In other embodiments, the two adjustment components 40 can also be arranged in a staggered manner.

[0062] In some embodiments, the bracket 10 is configured to be movable to drive the adsorption rack 21. Here, a roller is provided at the bottom of the bracket 10, so that the bracket 10 moves under the drive of the roller, thereby driving the adsorption rack 21 to move, so that the adsorption rack 21 can enter the interior of the heat press.

[0063] In this embodiment, there are two driving components 30, and the two driving components 30 are respectively located on both sides of the length direction of the adsorption frame 21, so that the adsorption frame 21 can be stably driven on both sides, so that the adsorption frame 21 can move stably.

[0064] In some embodiments, each driving assembly 30 includes at least one cylinder 31 and at least one crank arm 32. The cylinder 31 is connected to the bracket 10. The crank arm 32 is V-shaped, the bottom of the crank arm 32 is rotatably connected to the bracket 10, one end of the crank arm 32 is connected to the corresponding cylinder 31, and the other end is connected to the adsorption frame 21, and the crank arm 32 is configured to rotate under the drive of the cylinder 31, thereby driving the adsorption frame 21 to move vertically.

[0065] Here, the two ends of the crank arm 32 are connected to the cylinder 31 and the adsorption rack 21 respectively, and the bottom of the crank arm 32 is rotatably connected to the bracket 10, so that when the cylinder 31 drives one end of the crank arm 32 to rotate, the other end of the crank arm 32 rotates accordingly, thereby driving the adsorption rack 21 to move vertically up and down. In this embodiment, the rotation of the crank arm 32 is converted into the vertical movement of the adsorption rack 21, which can improve the driving efficiency of the driving assembly 30 and improve the working efficiency of the unloading machine 100.

[0066] In some embodiments, each driving assembly 30 includes two crank arms 32 and a cylinder 31, the cylinder 31 is connected to one crank arm 32, and each driving assembly 30 also includes a connecting rod 33, the connecting rod 33 is respectively connected to the two crank arms 32. Here, the connecting rod 33 is located between the two crank arms 32, so that the two crank arms 32 can rotate synchronously, thereby improving the stability and accuracy of the unloading machine 100. At this time, in the two crank arms 32, one end of the crank arm 32 away from the cylinder 31 is connected to the adsorption frame 21, and the other end is connected to the connecting rod 33, and one end of the crank arm 32 close to the cylinder 31 is connected to the adsorption frame 21, and the other end is respectively connected to the cylinder 31 and the adsorption frame 21.

[0067] In this embodiment, the plate unloader 100 includes two drive assemblies 30, and the connecting rods 33 in the two drive assemblies 30 are parallel to each other. The cylinders 31 in the two drive assemblies 30 are arranged obliquely and parallel to each other, and the transmission shafts of the two cylinders 31 are respectively connected to one end of the corresponding connecting rod 33.

[0068] In some embodiments, the bracket 10 further includes a second column 12 arranged in a vertical direction, and the crank arm 32 is rotatably connected to the second column 12. Here, the middle portion of the crank arm 32 is hinged to the hinge seat at the top of the second column 12, so that the crank can rotate along the second column 12. The second column 12 can also bear the gravity of the driving assembly 30 and the adsorption assembly 20, which can improve the load-bearing capacity of the unloader 100, thereby improving the structural stability and practicality of the unloader 100.
