Description

Technical Field

[0001] The present invention relates to the technical field of annealing, and particularly to a vertical annealing furnace for automobile headlights and a using method thereof. Background Art

[0002] Compared with ordinary headlights, through-type headlights have better ductility, which seemingly widens the horizontal distance and is more prominent in terms of technological sense and delicacy. Therefore, they are used by more and more new energy vehicles. In order to ensure that through-type headlights are not easily affected by the outside world during use, it is necessary to improve the performance strength of automobile headlights. During the production process of automobile headlights, annealing treatment is often carried out to improve the ductility, toughness, etc. of the headlights.

[0003] When traditional annealing equipment anneals automobile headlights, it usually puts the automobile headlights into the equipment and then heats them. In order to improve the annealing efficiency, the automobile headlights are usually transported by means of a chain drive device to transport the hanging baskets. For example, Chinese Patent with the application number CN201920106599.5 discloses a vertical annealing furnace for automobile headlights. The vertical annealing furnace includes a furnace body 19. An active sprocket 4 is provided in the upper inner part of the furnace body 19, and the active sprocket 4 is located in a heating zone 20. A tensioning sprocket 11 is provided in the lower inner part of the furnace body 19, and the tensioning sprocket 11 is located in a cooling zone 29. The active sprocket 4 and the tensioning sprocket 11 are connected by a circulating chain 21. A plurality of hanging baskets 13 are connected to the circulating chain 21 through connecting rods 22. The active sprocket 4 is connected to a driving first motor 5 provided on the furnace body 19 through a transmission shaft 6. The driving first motor 5 drives the active sprocket 4 to rotate, and then drives the circulating chain 21 between the active sprocket 4 and the tensioning sprocket 11 to move in a cycle, so as to realize the cyclic rotation of a plurality of hanging baskets 13 on the circulating chain 21 in the furnace body 19.

[0004] However, the above-mentioned method of transporting the hanging baskets by the chain has deficiencies. Since the hanging baskets are suspended on the chain of the conveying device, when the conveying device stops running, the hanging baskets and the workpieces in the hanging baskets will swing under the action of inertia, which easily causes the workpieces in the hanging baskets to collide with the hanging baskets. Especially for through-type headlights with large volume and long length, it is easier to cause damage to the outer surface of the workpieces. In this way, the annealing degree of different parts of the automobile headlights will be further uneven, greatly affecting the annealing quality of the automobile headlights. More seriously, when the swinging amplitude of the hanging basket is too large, the workpiece (headlight) will fall, which not only easily causes safety accidents, but also causes irreparable damage to the workpiece. Summary of the Invention

[0017] S1: When loading materials, first, clamp the frame body located at the bottom end of the first rack and corresponding to the transverse movement rack through the clamping mechanism on the first rack, drive the transverse movement rack to move under the empty hanging basket in the frame body through the transverse movement drive assembly, then drive the transverse movement rack to rise through the lifting drive assembly, and a supporting rod at one end of the transverse movement rack lifts the hanging basket in the frame body. Subsequently, drive the transverse movement rack to move back to the top of the lifting table through the transverse movement drive assembly. Then, place the workpiece in the hanging basket manually or by means of a mechanical hand device. Finally, drive the hanging basket on the transverse movement rack to move into the frame body through the transverse movement drive assembly, and drive the transverse movement rack to descend through the lifting drive assembly to place the hanging basket with the workpiece in the frame body. Subsequently, drive the transverse movement rack to move back to the top of the lifting table to complete the loading.

[0018] S2: While the hanging basket with the workpiece is moved into the clamped frame body in the first rack, the lower feeding mechanism pushes the empty frame body from the second lifting mechanism to the first lifting mechanism; the first lifting mechanism drives the frame body to rise and support it on the bottom surface of the frame body with the workpiece; then the clamping mechanism is released, and the first lifting mechanism moves all the stacked frame bodies upward by the height of one frame body. At this time, the empty frame body corresponds to the transverse moving frame for the next loading;

[0019] S3: After all the stacked frame bodies on the first rack are moved upward by the height of one frame body, the upper feeding mechanism pushes the topmost frame body advancing upward on the first rack to the top surface of the topmost frame body on the second rack;

[0020] S3: During unloading, first, the second lifting mechanism supports the bottom of the lowermost frame body on the second rack, and then the unloading lifting and transplanting machine moves the hanging basket in the lowermost frame body on the second rack out. After the workpiece in the hanging basket is taken away, the hanging basket is moved into the frame body, and the unloading is completed;

[0021] S4: After the unloading is completed, the second lifting mechanism moves all the stacked frame bodies downward by the height of one frame body, and then the clamping mechanism of the second rack clamps the second-to-last frame body moving downward step by step.

An adjacent first rack 3 and second rack 4 are vertically and uprightly arranged in the middle of the support frame 1, and the top ends of the first rack 3 and the second rack 4 both extend upward to the upper part inside the furnace body 2; a number of identical frames 5 are stacked along the vertical direction on the first rack 3 and the second rack 4 respectively, and a hanging basket 6 is placed in each frame 5, and a workpiece is placed in the hanging basket 6. Please refer to Figure 1-2 , a first lifting mechanism 7 is arranged at the bottom of the first rack 3, and the first lifting mechanism 7 supports the bottom of the lowermost frame 5 inside the first rack 3, and is used for moving the stacked frames 5 upward step by step. A second lifting mechanism 8 is arranged at the bottom of the second rack 4, and the second lifting mechanism 8 supports the bottom of the lowermost frame 5 inside the second rack 4, and is used for moving the stacked frames 5 downward step by step. A lower pushing mechanism 9 is arranged at the bottom of the support frame 1, and is used for pushing the lowermost frame 5 that descends step by step from the second lifting mechanism 8 to the second lifting mechanism 8. Clamping mechanisms 10 are respectively arranged at positions adjacent to the bottom of the first rack 3 and the second rack 4, and are used for clamping the lowermost frame 5 in the stack when the stacked frames 5 are separated from the support of the first lifting mechanism 7 or the second lifting mechanism 8. An upper pushing mechanism 11 is arranged at the top of the furnace body 2, and is used for moving the uppermost frame 5 that ascends step by step from the first rack 3 to the second rack 4.

[0044] Among them, please refer to Figure 1, a loading lifting and transferring machine 12 and an unloading lifting and transferring machine 13 are respectively arranged on both sides of the support frame 1. The loading lifting and transferring machine 12 is used to move the hanging basket 6 in the frame body 5 that rises step by step at the lower part of the first rack 3 out, and then move the hanging basket 6 into the frame body 5 after the workpiece is placed in the hanging basket 6, so as to complete the loading; the unloading lifting and transferring machine 13 is used to move the hanging basket 6 in the frame body 5 that descends step by step at the lower part of the second rack 4 out, and then move the hanging basket 6 into the frame body 5 after the workpiece in the hanging basket 6 is taken away, so as to complete the unloading. In this embodiment, the workpiece can be placed in and taken out of the hanging basket 6 by means of a manipulator or manual operation.

[0045] In the present invention, the frame bodies 5 with the hanging baskets 6 placed therein are stacked together. While the first lifting mechanism 7 moves the stacked plurality of frame bodies 5 upward step by step, the second lifting mechanism 8 moves the stacked plurality of frame bodies 5 downward step by step. During this process, the frame bodies 5 and the hanging baskets 6 will not swing or shake, improving the stability of workpiece transportation, enabling the transportation of larger workpieces, avoiding collision and dropping phenomena, not only avoiding safety accidents, but also ensuring the annealing quality of the workpieces; and the frame bodies 5 are stacked together, making the floor space occupied by the furnace body 2 small and the space utilization rate high; the hanging basket 6 does not need to be transported by a chain transmission device, reducing the generation of dust and contributing to improving the product quality.

[0046] In this embodiment, please refer to Figure 1-2 , the first rack 3 and the second rack 4 are both composed of four mutually parallel columns. Please refer to Figure 5 , a plurality of first guide wheels 31 are arranged at intervals along the vertical direction on the side surface of each column, and a plurality of second guide wheels 32 are arranged at intervals along the vertical direction on the end surface of each column. The axial directions of the first guide wheels 31 and the second guide wheels 32 are perpendicular. The outer wheel surfaces of the first guide wheels 31 are in contact with the side surfaces of the frame body 5, and the outer wheel surfaces of the second guide wheels 32 are in contact with the end surfaces of the frame body 5. The first guide wheels 31 and the second guide wheels 32 have the functions of guiding the lifting and positioning of the frame body 5.

[0047] Please refer to Figure 6-7, the first lifting mechanism 7 includes two relatively arranged lifting components 71. Each lifting component 71 includes a side bracket 711, a slide rail 712, and a pallet 713. The side bracket 711 is arranged outside the first frame 3. The number of the slide rails 712 is at least two, and they are arranged in parallel on the side bracket 711. The pallet 713 is arranged to be lifted and lowered on the two slide rails 712. The lifting component 71 includes a first motor 714 and a first driving gear (not shown in the figure) mounted on the pallet 713. The output shaft of the first motor 714 is in transmission connection with the first driving gear for driving the first driving gear to rotate. First racks 715 are respectively arranged on the two slide rails 712. The first driving gear meshes with one of the first racks 715. In this embodiment, a first driven gear 716 is rotatably mounted on the side bracket 711, and the first driven gear 716 meshes with the other first rack 715. When the first motor 714 drives the first driving gear to rotate, while the first driving gear rolls along the height direction of the first rack 715, it drives the pallet 713 to lift and lower along the height direction of the slide rail 712, so that the pallet 713 jacks up all the stacked boxes 5 upward or drives the lowermost box 5 downward. In this embodiment, the structure of the second lifting mechanism 8 is the same as that of the first lifting mechanism 7, and will not be described in detail here.

[0048] Please refer to Figure 1 and Figure 8 , the pushing mechanism 9 includes a chassis 91, a screw (not shown in the figure), a pushing block 92, and a second motor 93. The chassis 91 is arranged between the side brackets 711 of the two lifting components 71. The two ends of the screw are rotatably mounted on the chassis 91. The lower part of the pushing block 92 is sleeved on the screw through a thread to move along the axial direction of the screw when the screw rotates, so as to push the box 5. The second motor 93 is mounted on the chassis 91, and the output shaft of the second motor 93 is connected to one end of the screw for driving the screw to rotate.

[0049] In this embodiment, the pushing block 92 is located on the side of the second lifting mechanism 8 away from the first lifting mechanism 7, and the top height of the pushing block 92 is higher than the bottom surface height of the box 5, so that the pushing block 92 can push the box 5 and the hanging basket 6 from which the workpiece has been taken on the second lifting mechanism 8 onto the pallet 713 of the first lifting mechanism 7. Subsequently, the first lifting mechanism 7 jacks up the box 5 from which the workpiece has been taken together with all the stacked boxes 5 above it, so that the box 5 from which the workpiece has been taken rises to a position corresponding to the horizontal of the loading lifting and transplanting machine 12, and then the loading lifting and transplanting machine 12 loads the hanging basket 6 in the box 5 from which the workpiece has been taken.

[0050] Among them, please refer to Figure 6-7, on one side of the top surface of the pallet 713 close to the slide rail 712, a number of first guide cylinders 717 arranged in a straight line are spaced apart. The first guide cylinders 717 are rotatably arranged on the top surface of the pallet 713, and the axis of the first guide cylinder 717 is perpendicular to the top surface of the pallet 713.

[0051] Please refer to Figure 2 and Figure 4 , the clamping mechanism 10 includes a first cylinder 101 arranged on the support frame 1 and a clamping plate 102 connected to one end of the piston rod of the first cylinder 101. The clamping plate 102 clamps the side surface of the frame 5 to prevent the frame 5 that loses the support of the first lifting mechanism 7 or the second lifting mechanism 8 from falling. Please refer to Figure 1 , in this embodiment, the frame 5 clamped by the clamping plate 102 corresponds to the positions of the loading lifting and transferring machine 12 and the unloading lifting and transferring machine 13. In this way, the loading lifting and transferring machine 12 can take out the hanging basket 6 from the clamped frame 5, place workpieces in the hanging basket 6 and move the hanging basket 6 into the clamped frame 5. The unloading lifting and transferring machine 13 takes out the hanging basket 6 with workpieces from the clamped frame 5, and after taking away the workpieces, moves the empty hanging basket 6 into the clamped frame 5, thereby completing the loading and unloading.

[0052] The frame 5 is a box structure with openings on four sides and the top surface. The bottom surface of the frame 5 is a mesh plate, so that the workpieces in the hanging basket 6 are heated evenly during annealing. In this embodiment, openings may not be provided on both sides of the frame 5 to facilitate clamping by the first cylinder 101.

[0053] Please refer to Figure 9-10 , the loading lifting and transferring machine 12 includes a loading frame 121, a lifting platform 122 and a transverse moving frame 123. The loading frame 121 is arranged on one side of the first frame 3. The lifting platform 122 is arranged on the loading frame 121 in a lifting manner. The transverse moving frame 123 is arranged on the lifting platform 122 in a horizontal moving manner. The loading lifting and transferring machine 12 includes a lifting drive assembly 124.

A second driving gear (not shown in the figure) is rotatably arranged on the output shaft of the third motor 1242. A second rack (not shown in the figure) meshing with the second driving gear is rotatably arranged on the support column 1241. Driven by the third motor 1242, when the second driving gear rotates, the rack moves up or down, so as to realize the lifting of the support column 1241 and the lifting platform 122.

[0054] The loading lifting and transferring machine 12 includes a transverse moving drive assembly 125. The transverse moving drive assembly 125 includes a conveyor belt 1251 and a fourth motor 1252. Please refer toFigure 10 , the conveyor belt 1251 is horizontally movably arranged on the lifting platform 122 and connected to the transverse moving frame 123. Please refer to Figure 9 , the fourth motor 1252 is installed on the lifting platform 122. The output shaft of the fourth motor 1252 is connected to the conveyor belt 1251 and is used to drive the conveyor belt 1251 and the transverse moving frame 123 to horizontally move on the lifting platform 122, and transfer the hanging basket 6 in the frame body 5 through the transverse moving frame 123. In this embodiment, the structure of the blanking lifting and transferring machine 13 is the same as that of the feeding lifting and transferring machine 12, and will not be described in detail here.

[0055] Among them, please refer to Figure 3 , the bottom surface of the hanging basket 6 is a grid structure for ventilation. Please refer to Figure 13-14 , both sides of the hanging basket 6 respectively extend outward to form hanging ears 61. Please refer to Figure 15 , the hanging ears 61 are formed with side stops 62 bent downward at one end relative to the hanging basket 6, and a slot 63 is formed between the retaining edge 1232 and the side wall of the hanging basket 6. Please refer to Figure 9 , one end of the transverse moving frame 123 is connected with two oppositely arranged support rods 1231. The two support rods 1231 respectively extend into and support at the bottom of the corresponding hanging ear 61 along the direction of the slot 63. Please refer to Figure 16 , the two ends of the support rod 1231 are formed with retaining edges 1232 bent upward to prevent the hanging basket 6 from falling, and improve the conveying stability and safety of the hanging basket 6.

[0056] During feeding, please refer to Figure 4 , first, the two clamping plates 102 clamp the frame body 5 corresponding to the bottom end of the first frame 3 and the transverse moving frame 123. Please refer to Figure 9-10, the fourth motor 1252 drives the conveyor belt 1251 to move towards the first rack 3, so that the transverse moving frame 123 moves below the empty hanging basket 6 in the frame body 5, and aligns the supporting rod 1231 with both ends of the side ear; then driven by the third motor 1242, the support column 1241, the lifting platform 122 and the transverse moving frame 123 rise together. At this time, the hanging basket 6 hovers on the supporting rod 1231; subsequently, the fourth motor 1252 drives the conveyor belt 1251 to move in the direction away from the first rack 3 until the transverse moving frame 123 resets to the top of the lifting platform 122; then the workpiece can be placed in the hanging basket 6 manually or by a manipulator device; finally, the fourth motor 1252 and the conveyor belt 1251 drive the transverse moving frame 123 to move into the clamped frame body 5 again, and the third motor 1242 drives the support column 1241, the lifting platform 122 and the transverse moving frame 123 to descend together to place the hanging basket 6 filled with the workpiece in the frame body 5. Subsequently, driven by the fourth motor 1252, the transverse moving frame 123 moves and resets to the top of the lifting platform 122, thus completing the feeding; the discharging action of the discharging lifting transfer machine 13 is the same as the feeding action of the feeding lifting transfer machine 12, and the only difference is that after the transverse moving frame 123 resets to the lifting platform 122, the workpiece in the hanging basket 6 is taken away manually or by a manipulator device.

[0057] Please refer to Figure 11-12 , the upper feeding mechanism 11 includes a top beam 111, a moving frame 112, a hanging frame 113 and a transverse pushing assembly 114.

Please refer to Figure 9-10, the transverse movement driving component 125 drives the transverse movement frame 123 to move below the empty hanging basket 6 in the frame body 5, and then the lifting driving component 124 drives the transverse movement frame 123 to rise. The supporting rod 1231 at one end of the transverse movement frame 123 lifts the hanging basket 6 in the frame body 5. Subsequently, the transverse movement driving component 125 drives the transverse movement frame 123 to move back to the top of the lifting platform 122. Then, the workpiece is placed in the hanging basket 6 manually or by a manipulator device. Finally, the transverse movement driving component 125 drives the hanging basket 6 on the transverse movement frame 123 to move into the frame body 5, and the lifting driving component 124 drives the transverse movement frame 123 to descend to place the hanging basket 6 with the workpiece in the frame body 5. Subsequently, the transverse movement driving component 125 drives the transverse movement frame 123 to move back to the top of the lifting platform 122, and the loading is completed;

At this time, the empty frame body 5 corresponds to the transverse movement frame 123 for the next loading;

[0065] S3: Please refer to Figure 1 , when all the stacked frame bodies 5 on the first rack 3 are moved upward by the height of one frame body, please refer to Figure 11-12 , the upper pushing mechanism 11 pushes the topmost frame body 5 advanced upward on the first rack 3 to the top surface of the topmost frame body 5 on the second rack 4;

[0066] S3: When unloading, please refer to Figure 1 , first, the second lifting mechanism 8 supports the bottom of the lowermost frame body 5 on the second rack 4, and then the unloading lifting and transplanting machine 13 moves the hanging basket 6 in the lowermost frame body 5 on the second rack 4 out. After the workpiece in the hanging basket 6 is taken away, the hanging basket 6 is moved back into the frame body 5, and the unloading is completed;

[0067] S4: After the unloading is completed, the second lifting mechanism 8 moves all the stacked frame bodies 5 downward by the height of one frame body, and then the clamping mechanism 10 of the second rack 4 clamps the second-to-last frame body 5 moving downward step by step. The second lifting mechanism 8 drives the lowermost empty frame body 5 to continue to descend to the preset height. Please refer to Figure 6 , after the loading is completed, the lower pushing mechanism 9 can push the empty frame body 5 from the second lifting mechanism 8 to the first lifting mechanism 7.
