[0014] Beneficial Effects

[0015] Compared with the prior art, the advantages of the automatic sheet-to-frame transport and automatic frame entry and exit of the automatic oven of the present invention are:

[0016] 1. The first manipulator, the third manipulator and the mouth frame positioning seat cooperate to complete the placement and framing of the thin plate and the mouth frame, and then the second manipulator moves the framed mouth frame to the storage compartment of the oven, and then the storage compartment moves the framed mouth frame to the oven for baking. After baking, the mouth frame returns to the mouth frame positioning seat for unframing. The whole process does not require manual operation, realizing fully automated production, reducing labor costs, and high product quality stability.

[0017] 2. The third robot moves the thin plate for loading and unloading, further improving the degree of automation.

[0018] 3. The loading and unloading temporary storage racks are used to temporarily store thin plates. They can play a buffering role when the loading and unloading speeds do not match the speeds of the thin plate assembly and disassembly frames during the production process.

[0019] 4. The support plate of the mouth frame storage structure can be moved horizontally through the support plate horizontal movement driving mechanism, so that the second manipulator can take and place the mouth frames located at the storage position 1 and the storage position 2 respectively.

[0020] 5. The second mouth frame clamping part of the second manipulator is provided with a plurality of grooves, which can take and place a plurality of mouth frames at the same time, thereby improving the transportation efficiency.

[0021] 6. The air volume of the oven should not be too large during the baking process of thin plates. If the air volume is too large, the thin plates will flutter and collide, causing scratches on the products. The general design requires the inverter to be adjusted down to prevent the thin plates from fluttering or colliding. However, reducing the air volume directly affects the temperature uniformity of the oven and the baking yield of the product, so the two are contradictory. This patent uses a special mouth frame design to fix the thin plates so that they will not flutter or collide during the baking process. At the same time, the air volume of the oven can be adjusted independently according to the uniformity requirements to ensure good temperature uniformity of the oven. Thereby effectively improving the baking yield of the product. In addition, the thin plates are fixed with a mouth frame, and the placement is changed from horizontal to vertical. The distance between the plates is controlled to the minimum. Under the condition of the same production capacity, the external dimensions of the equipment can be effectively reduced, directly reducing the space occupied by the client equipment.

[0039] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0040] Example

[0041] The specific embodiments of the present invention are as follows Figures 1 to 15As shown, an automatic oven for automatic sheet-to-frame transport and automatic mouth frame entry and exit includes an oven 1 for baking thin plates 00. A storage compartment 11 capable of moving in and out of the oven 1 is connected to the oven 1 through a storage compartment driving mechanism 13, and an oven door 12 is connected to the outer side of the storage compartment 11. The storage compartment driving mechanism 13 can be driven by a hydraulic cylinder or a linear motor, and the storage compartment 11 can be moved out of or into the oven cavity of the oven 1 by telescoping. The automatic oven also includes a mouth frame storage structure 8, a mouth frame 9, and a mouth frame positioning seat 7 adapted to the mouth frame 9. The mouth frame 9 is used to fix the thin plate 00. A first manipulator 4 for moving the thin plate 00 and the mouth frame 9 is provided between the mouth frame positioning seat 7 and the mouth frame storage structure 8, and a second manipulator 2 for moving the mouth frame 9 is provided between the mouth frame storage structure 8 and the storage compartment 11.

[0042] A third manipulator 5 for moving the thin plate 00 is also provided on one side of the mouth frame positioning seat 7. The third manipulator 5 is a multi-joint manipulator. The third manipulator 5 is provided with two supporting rods 51 for supporting the thin plate 00. The automated oven also includes a loading temporary storage rack 61 and a unloading temporary storage rack 62 for storing the thin plate 00. Both the loading temporary storage rack 61 and the unloading temporary storage rack 62 are multi-layer structures, which can temporarily store multiple thin plates 00 arranged up and down at the same time. The openings on both the loading temporary storage rack 61 and the unloading temporary storage rack 62 for the thin plates 00 to move in and out are facing the side where the third manipulator 5 is located.

[0043] A loading roller conveyor mechanism 63 is provided below the loading temporary storage rack 61, and a discharging roller conveyor mechanism 64 is provided below the discharging temporary storage rack 62. The rollers of the loading roller conveyor mechanism 63 and the discharging roller conveyor mechanism 64 can rotate and support the horizontally placed thin plates 00. The loading roller conveyor mechanism 63 is used to convey the thin plates 00 to be baked from the outside of the equipment to the bottom of the loading temporary storage rack 61. When the conveying volume of the loading roller conveyor mechanism 63 is large and the thin plates 00 are not framed with the mouth frame 9 in time, the third manipulator 5 places some of the thin plates 00 on the loading temporary storage rack 61 for temporary storage. The discharging roller conveyor mechanism 64 is used to convey the baked thin plates 00 to the next station. When the number of thin plates 00 unloaded from the mouth frame 9 is large and there is no time to convey them through the discharging roller conveyor mechanism 64, the third manipulator 5 places some of the thin plates 00 on the discharging temporary storage rack 62 for temporary storage.

[0044] In this embodiment, the mouth frame storage structure 8, the mouth frame positioning seat 7, the first manipulator 4, the loading temporary storage rack 61 and the unloading temporary storage rack 62 are all arranged on the frame 3, the third manipulator 5 is located on one side of the frame 3, and the third manipulator 5, the frame 3, and the oven 1 are arranged in sequence. The frame 3 is also provided with a fan filter unit 15 located outside the mouth frame storage structure 8, and the fan filter unit 15 includes a cover body, the bottom of the inner cavity of the cover body is connected to the space where the mouth frame storage structure 8 is located, and the top of the cover body is connected to an exhaust port 16 through a fan and a filter.

[0045] There are four ovens 1 arranged in two rows, with two ovens in each row. Each oven is provided with six oven cavities. The oven doors 12 of the two rows of ovens 1 are arranged with their openings facing each other, and the oven doors 12 are installed on the outside of the storage compartments 11 .

[0046] The first manipulator 4 includes a first moving assembly 41 and a base plate 42 connected to each other, wherein the first moving assembly 41 includes a first transverse drive mechanism 411, a first longitudinal drive mechanism 412, and a first lifting drive mechanism 413 connected in sequence, which respectively move along the X-axis, the Y-axis, and the Z-axis, and all of them adopt a screw drive structure, that is, the screw is driven to rotate by a motor, and the screw drives the slider to slide along the guide rail by means of threaded engagement. The first transverse drive mechanism 411 is installed on the frame 3, and the lower end of the first lifting drive mechanism 413 is connected to the base plate 42. The base plate 42 can be moved in three directions of the X-axis, the Y-axis, and the Z-axis through the first moving assembly 41.

[0047] A plurality of suction cups 421 for adsorbing the thin plate 00 are provided at the bottom of the base plate 42. The suction cups 421 can form negative pressure through an air pump. A first telescopic mechanism 423 is provided on the base plate 42. The output end of the first telescopic mechanism 423 is connected to a limit hook 424 for hooking the bottom edge of the thin plate 00.

[0048] The first manipulator 4 also includes a fixed plate 43 fixed relative to the bottom plate 42. In this embodiment, the fixed plate 43 is fixed relative to the moving end of the first lifting drive mechanism 413, and the fixed plate 43 is arranged vertically. The fixed plate 43 is connected to the cross plate 44 through the first lifting mechanism 432. The first lifting mechanism 432 also adopts a screw drive structure. The screw of the screw drive structure is rotatably connected to the fixed plate 43, and the slider of the screw drive structure is fixedly connected to the cross plate 44. The screw and the slider are threaded. A guide rail 431 is provided on the fixed plate 43, and the cross plate 44 is slidably matched with the guide rail 431. The two ends of the cross plate 44 are each connected to a cantilever 46 through a horizontally arranged second telescopic mechanism 45 (a telescopic hydraulic cylinder or a cylinder can be used), and each cantilever 46 is connected to a first mouth frame clamping part 47 through a first rotating mechanism 48, and the two first mouth frame clamping parts 47 are arranged relative to each other. The rotation axis of the first mouth frame clamping part 47 is arranged horizontally and parallel to the plane where the clamped mouth frame 9 is located.

[0049] The mouth frame storage structure 8 comprises a horizontally arranged support plate 81, the support plate 81 is connected to a support plate transverse driving mechanism 83, and the support plate transverse driving mechanism 83 is installed on the frame 3. The support plate 81 is provided with storage position 1, storage position 2, and storage position 3 arranged in sequence along its transverse direction.

[0050] Storage position one is used for placing the mouth frame 9 with the thin plate 00 just installed, storage position two is used for placing the mouth frame 9 with the thin plate 00 just unloaded from the oven 1, and storage position three is used for placing the idle mouth frame 9 (the mouth frame 9 has no thin plate 00).

[0051] The edges of both sides of the support plate 81 are also provided with limiting parts 82 for limiting the edges of each vertically placed mouth frame 9. For example, a rod body is arranged on both sides of the support plate 81, and a plurality of limiting wheels are rotatably connected to the rod body. The wheel surface of each limiting wheel has a concave structure in the middle. The edge of the mouth frame 9 can cooperate with the concave part of the wheel surface of the limiting wheel. The limiting wheel prevents the mouth frame 9 from moving along the direction of the rod body, so that the mouth frame 9 on the support plate 81 can maintain a certain distance, which is convenient for corresponding to the groove 261 of the second mouth frame clamping part 26 of the second manipulator 2.

[0052] The second manipulator 2 includes a second transverse driving mechanism 21, a second transverse sliding seat 22, a second lifting driving mechanism 23, a second lifting sliding seat 24, a third telescopic mechanism 25 and a second mouth frame clamping part 26 connected in sequence. The second transverse driving mechanism 21 is installed above the oven 1 and the two are relatively fixed. The second transverse driving mechanism 21 is arranged horizontally, and its length direction is perpendicular to the opening direction of the storage compartment 11. There are two second mouth frame clamping parts 26 and they are arranged oppositely. In this embodiment, there are two second mouth frame clamping parts 26 and the third telescopic mechanism 25 and they are connected one by one. Driven by the third telescopic mechanism 25 (which can be a hydraulic cylinder or a cylinder), the two second mouth frame clamping parts 26 can be relatively horizontally close or far away. The opposite side of the two second mouth frame clamping parts 26 is provided with a groove 261 adapted to the edge of the mouth frame 9. The number of grooves 261 on each second mouth frame clamping part 26 is at least two and arranged in parallel. In this embodiment, each second opening frame clamping portion 26 is provided with eight vertically arranged grooves 261 , that is, the second manipulator 2 can move eight opening frames 9 at a time.

[0053] The two opposite sides of the inner cavity of the storage compartment 11 are provided with stoppers adapted to the edge of the mouth frame 9, each stopper is composed of two stoppers 111 arranged at intervals, and the stoppers 111 are connected to the storage compartment 11. When in use, the edge of the mouth frame 9 is vertically inserted between the two stoppers 111.

[0054] The middle of the mouth frame 9 is provided with a hollow portion whose shape matches that of the thin plate 00. The mouth frame 9 is provided with a thin plate clamp for clamping the edge of the thin plate 00. The thin plate clamp includes a first thin plate clamping portion 91 and a second thin plate clamping portion 92 arranged opposite to each other at their front ends. The second thin plate clamping portion 92 is fixedly connected to the mouth frame 9. The middle of the first thin plate clamping portion 91 is rotatably connected to one end of a connecting rod 95, and the other end of the connecting rod 95 is rotatably connected to the mouth frame 9. A sliding pin 94 and a spring 93 are provided between the rear end of the first thin plate clamping portion 91 and the mouth frame 9. One end of the sliding pin 94 is rotatably connected to the rear end of the first thin plate clamping portion 91. The sliding pin 94 passes through the mouth frame 9 and the two are slidably connected along the axial direction of the sliding pin 94. The mouth frame 9 is square, and two thin plate clamps are provided on each edge thereof.

[0055] A mouth frame supporting portion 71 is provided in the middle of the mouth frame positioning seat 7 , and a clip opening driving device 72 for driving the thin plate clip of the mouth frame 9 to open is also provided on the mouth frame positioning seat 7 .

[0056] In this embodiment, the clamp opening driving device 72 is a clamping mechanism, and the number of the clamping mechanisms corresponds to the number of the thin plate clamps, both of which are 8. The clamping mechanism includes a third clamping portion and a fourth clamping portion that rotate relative to each other, the third clamping portion corresponds to the rear end of the first thin plate clamping portion 91, and the fourth clamping portion corresponds to the mouth frame 9. When the third clamping part and the fourth clamping part of the clamp opening driving device 72 are away from each other, the two do not contact the thin plate clamp on the mouth frame 9, and the thin plate clamp is in a closed state under the action of the spring 93; when the fourth clamping part of the clamp opening driving device 72 rotates upward and presses the lower edge of the mouth frame 9, the third clamping part of the clamp opening driving device 72 rotates downward and presses the rear end of the first thin plate clamping part 91, and the rear end of the first thin plate clamping part 91 is pressed downward, and the front end of the first thin plate clamping part 91 is tilted, then the thin plate clamp is opened, and the thin plate 00 can be placed downward between the first thin plate clamping part 91 and the second thin plate clamping part 92, or the thin plate 00 can be lifted up. The clamping mechanism of the clamp opening driving device 72 is laterally staggered with the upper and lower ends of the sliding pin 94 during the action process to prevent the sliding pin 94 from blocking the action of the clamping mechanism.

[0057] The working process of the automatic oven is as follows: the loading roller conveyor mechanism 63 continuously conveys the thin plate 00 to be baked to the bottom of the loading temporary storage rack 61, and the third robot 5 lifts the thin plate 00 through the supporting rod 51 and moves it to the side of the mouth frame positioning seat 7. The transverse plate 44, cantilever 46 and first mouth frame clamping part 47 of the first manipulator 4 are lowered relative to the fixed plate 43 and avoid the bottom plate 42 under the action of the first lifting mechanism 432. The first mouth frame clamping part 47 is driven by the first moving assembly 41 to move to the storage position three of the supporting plate 81. The two symmetrical first mouth frame clamping parts 47 clamp the idle mouth frame 9 placed vertically on the storage position three under the action of the second telescopic mechanism 45. The mouth frame 9 moves with the first manipulator 4 to above the mouth frame positioning seat 7. The mouth frame 9 is rotated to a horizontal arrangement under the action of the first rotating mechanism 48 (in this process, the bottom plate 42 is always located above the mouth frame 9 to avoid interference with the rotating mouth frame 9), and is placed above the mouth frame supporting part 71 of the mouth frame positioning seat 7 by the first manipulator 4. Then the base plate 42 of the first manipulator 4 moves to the top of the thin plate 00 supported by the supporting rod 51 of the third manipulator 5, the suction cup 421 of the base plate 42 sucks the top surface of the thin plate 00, and the first telescopic mechanism 423 on the base plate 42 drives the limiting hook 424 to retract inward, so that the bending part of the lower end of the limiting hook 424 is located below the edge of the thin plate 00 to prevent the thin plate 00 from falling accidentally, and then the thin plate 00 is moved by the first manipulator 4 to the hollow part of the mouth frame 9 located at the mouth frame positioning seat 7. The clamping mechanism of the clamp opening driving device 72 drives the thin plate clamps on the mouth frame 9 to open, and the first manipulator 4 places the thin plate 00 between the opened thin plate clamps. The clamping mechanism of the clamp opening driving device 72 releases the thin plate clamps, and the thin plate clamps close and clamp the edge of the thin plate 00 under the reset action of the spring 93. At this time, the thin plate 00 and the mouth frame 9 are relatively fixed, and the framing is completed. The first manipulator 4 releases the thin plate 00 and moves the framed mouth frame 9 on the mouth frame supporting portion 71 to the storage position 1 of the supporting plate 81, and allows the mouth frame 9 to be placed vertically. In this embodiment, the storage position 1 can simultaneously store 8 framed mouth frames 9 arranged in parallel.

[0058] The storage compartment 11 in the oven 1 that has completed baking is opened under the action of the storage compartment driving mechanism 13, and the two second mouth frame clamping parts 26 of the second manipulator 2 move the two sides of the storage compartment 11 and clamp the eight mouth frames 9 with thin plates 00 arranged in parallel in the storage compartment 11, and the eight mouth frames 9 are simultaneously pulled upward from the storage compartment 11 by the second lifting driving mechanism 23, and then the eight mouth frames 9 that have completed baking are translated to the storage position 2 of the supporting plate 81 by the second transverse driving mechanism 21 and placed, as shown in FIG. Fig.13 Then the support plate 81 is translated under the action of the support plate transverse driving mechanism 83, so that the storage position 1 where the 8 newly framed mouth frames 9 are placed is moved to the position where the storage position 2 is just located, as shown in FIG. Fig.14The second manipulator 2 moves the eight newly framed mouth frames 9 to an empty storage compartment 11, and the storage compartment 11 enters the oven 1 for baking.

[0059] The first manipulator 4 moves the eight mouth frames 9 with thin plates 00 that have been baked on the second storage position to the mouth frame positioning seat 7 in sequence, removes the thin plates 00 from the mouth frames 9, lifts the thin plates 00 through the suction cups 421 on the bottom plate 42 of the first manipulator 4, and then receives the thin plates 00 through the third manipulator 5 and places them on the unloading roller conveyor mechanism 64 or the unloading temporary storage rack 62. Then the first manipulator 4 moves the mouth frames 9 with the thin plates 00 removed to the third storage position of the support plate 81, where they are placed vertically and temporarily stored. The support plate 81 is translated under the action of the support plate transverse driving mechanism 83, and the idle storage position two returns to the translation path of the second manipulator 2, ready to receive the next batch of eight mouth frames 9 with thin plates 00 that have been baked. At this time, the storage position one is idle, ready to store a new batch of framed and to-be-baked mouth frames 9. Fig.15 shown.
