Description

Technical Field

[0001] This invention belongs to the field of loudspeaker manufacturing technology, and in particular relates to an automatic pressure-maintaining hot air drying oven. Background Technology

[0002] After assembling the speaker components (mainly the diaphragm and the bracket), AB glue is injected onto the plane of the bracket relative to the diaphragm. After the diaphragm and bracket are combined, they are bonded together using AB glue. To improve mass production efficiency, the bonded speaker components are baked in an oven at a certain high temperature for a period of time to allow the AB glue to cure quickly through heat curing.

[0003] Because the diaphragm is lightweight and soft, existing technologies often use manual pressure-holding clamps to press onto the speaker components to ensure proper adhesion. This allows for tight contact between the support and the diaphragm, guaranteeing strong adhesion. After baking in an oven, the pressure-holding clamps are then manually removed from the speaker components. However, manual operation makes it difficult to ensure that the pressure and position of each press are completely consistent, resulting in inconsistent product quality, low production speed, and risks of equipment damage and operator injury due to operational errors. Furthermore, it significantly increases labor costs.

[0004] Based on the above, there is an urgent need for an automatic pressure-maintaining hot air drying oven to solve the technical problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic pressure-holding hot air drying oven to reduce human intervention, increase production speed, ensure equipment safety, and reduce labor costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

It can return the removed pressurizing fixture to the pressurizing fixture release mechanism. It can also control the control mechanism to start the pressurizing fixture release mechanism or the pressurizing fixture removal mechanism according to the actual position of the product fixture detected, so that the pressurizing fixture is stacked on the product fixture or the pressurizing fixture is removed from the baking fixture.

[0012] Optionally, the pressurization fixture detection feedback mechanism includes a feedback belt assembly and a detection component, both connected to the control mechanism. The input end and output end of the feedback belt assembly are respectively connected to the pressurization fixture taking mechanism and the pressurization fixture placing mechanism, and can carry the pressurization fixture.

When the first sensor detects that the pressurizing fixture is on the feedback belt assembly and is in a first designated position, the first sensor can send a signal to the first blocking interval sensing drive to cause the output shaft of the first blocking interval sensing drive to extend, thereby blocking the adjacent pressurizing fixture.

[0016] Optionally, the pressurized tooling detection feedback mechanism further includes a second blocking interval sensing drive, which is located upstream of the first blocking interval sensing drive along the conveying direction of the feedback belt assembly.

[0017] When the second blocking interval sensing drive detects that the pressurizing fixture is on the return belt assembly and in a second designated position, the output shaft of the second blocking interval sensing drive can extend to block the adjacent pressurizing fixture.

When the second sensor detects that the tooling to be baked is in a preset position, it can control the control mechanism to start the feeding pusher so as to push the tooling to be baked into the box through the feeding pusher.

[0024] Optionally, multiple boxes are fixed in the vertical direction inside the box to divide the box into multiple baking areas;

[0025] The oven feeding mechanism also includes a feeding lifting assembly, which includes a feeding lifting frame and a feeding lifting platform. The feeding lifting frame is fixed vertically between the support and the entrance of the oven body. The feeding lifting platform is slidably mounted on the feeding lifting frame vertically.

[0026] Optionally, the oven feeding mechanism further includes a buffer platform located between the output end of the feeding conveying component and the inlet of the oven body, and flush with the height of the output end of the feeding conveying component, so that the buffer platform can receive and buffer the ejected baking fixture;

The buffer platform is correspondingly disposed on the first pusher. The second pushers are correspondingly disposed on the baking area. The first pusher can push the tooling to be baked on the buffer platform to the feeding lifting platform. The second pushers can push the tooling to be baked on the feeding lifting platform to the corresponding baking area.

[0028] Optionally, the housing further includes a uniform heating element and side plates, wherein:

The pressurizing fixture detection and feedback mechanism can control the control mechanism to automatically activate either the pressurizing fixture placement mechanism or the pressurizing fixture removal mechanism based on the detected actual position of the product fixture. This allows the pressurizing fixture placement mechanism to accurately press the pressurizing fixture onto the product fixture to apply pressure, or the pressurizing fixture removal mechanism to remove the pressurizing fixture from the dried fixture for stacking with the next product fixture. This automatic pressure-holding hot air drying oven reduces human intervention in the pressurizing fixture placement and removal process. While ensuring firm bonding of speaker components, it also improves the consistency and accuracy of the pressure applied and the position of the pressurizing fixture on the product fixture, effectively guaranteeing production efficiency and product quality.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0062] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0063] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0064] The following is combined with Figures 1 to 14 The present invention provides an automatic pressure-holding hot air oven capable of baking several speaker components 110 mounted on a product fixture 100, and specific embodiments thereof.

[0065] Specifically, the automatic pressure-holding hot air oven includes a pressurizing fixture placement mechanism 1, a housing 2, a pressurizing fixture removal mechanism 3, a pressurizing fixture detection and feedback mechanism 4, and a control mechanism. The pressurizing fixture placement mechanism 1, housing 2, pressurizing fixture removal mechanism 3, and pressurizing fixture detection and feedback mechanism 4 are all electrically connected to the control mechanism. The pressurizing fixture placement mechanism 1 is located upstream of the housing 2 and can stack the pressurizing fixture 200 onto the top of the product fixture 100 to form a fixture 400 to be baked. The pressurizing fixture 200 is equipped with several pressurizing clamps 210 corresponding to the speaker components 110. The housing 2 is used to bake the fixture 400 to form a baked fixture 500. The pressurizing fixture removal mechanism 3 is located downstream of the housing 2 and can remove the pressurizing fixture from the baked fixture 500. The pressure fixture 200 is removed; the pressure fixture detection and feedback mechanism 4 is connected to the pressure fixture removal mechanism 3 and the pressure fixture release mechanism 1, and can return the removed pressure fixture 200 to the pressure fixture release mechanism 1. According to the actual position of the detected product fixture 100, the control mechanism can start the pressure fixture release mechanism 1 or the pressure fixture removal mechanism 3 so that the pressure fixture 200 is stacked on the product fixture 100 or the pressure fixture 200 in the baked fixture 500 is removed.

[0066] For example, in actual use, when the product fixture 100 is located in the first station (i.e., the product fixture 100 is positioned opposite the pressure fixture 200 on the pressure fixture mechanism 1), such as... Figure 4When the pressurizing fixture detection and feedback mechanism 4 sends a working signal to the control mechanism to start the release pressurizing fixture mechanism 1, the release pressurizing fixture mechanism 1 can accurately press the pressurizing fixture 200 obtained from the pressurizing fixture detection and feedback mechanism 4 onto the pressurizing fixture 200. It can be understood that the control system can also set the displacement of the release pressurizing fixture mechanism 1 to ensure the consistency of the stacking pressure each time. When the product station is located in the second station (i.e., the product fixture 100 is set opposite to the pressurizing fixture mechanism 3, such as...), Figure 10 When the pressure fixture detection and feedback mechanism 4 is shown, it can send a working signal to the control mechanism to start the pressure fixture removal mechanism 3. At this time, the pressure fixture removal mechanism 3 can remove the pressure fixture 200 on the dried fixture, so that the removed pressure fixture 200 can be returned to the pressure fixture release mechanism 1 for stacking with the next product fixture 100.

[0067] In this way, the pressure fixture 200 achieves the working process of "automatic stacking - automatic removal - automatic return" through the control mechanism, thereby effectively reducing human intervention. This ensures that the automatic pressure-holding hot air oven can firmly bond the horn parts 110, and ensures the consistency and accuracy of the pressure pressure and position of the pressure fixture 200 on the product fixture 100. Production efficiency and product quality are improved, and while enhancing equipment safety, the cost of manual operation is reduced.

[0068] Optionally, such as Figure 1 As shown, in this embodiment, the automatic pressure-holding hot air oven also includes a feeding conveying mechanism 5 to automatically transport the product tooling 100 through the first station to the oven body 2, further reducing human intervention. Specifically, the feeding conveying mechanism 5 includes a feeding conveying component 51 and a cylinder pushing component 52, both connected to the control mechanism. The input end of the feeding conveying component 51 is connected to the feeding end 300, and the output end of the feeding conveying component 51 is connected to the oven body 2, so that the feeding conveying component 51 can automatically receive the product tooling 100 output from the feeding end 300, eliminating the step of manual material handling. The pressurizing tooling mechanism 1 is located in the middle position of the feeding conveying mechanism 5. The cylinder pushing component 52 is movably mounted on the feeding conveying component 51 and can push the product tooling 100 located at the feeding end 300 into the oven body 2 via the feeding conveying component 51. With the above settings, the product fixture 100, under the pushing action of the cylinder pushing component 52, first passes through the first station to stack the product fixture 100 and the pressurizing fixture 200, and then is automatically pushed into the box 2 for baking. While eliminating manual material handling, it achieves the purpose of automatically entering the box 2 with the fixture 400 to be baked, thereby further improving the intelligent automation of the automatic pressure-holding hot air oven.

[0069] For example, in this embodiment, such as Figure 2As shown, the feeding and conveying assembly 51 includes a first conveyor belt 511, a second conveyor belt 512, and a third conveyor belt 513. The cylinder pushing assembly 52 includes a first feeding cylinder 521 and a second feeding cylinder 522. The output end of the second feeding cylinder 522 is extendable along the X-axis, and the third conveyor belt 513 extends along the Y-axis and is connected to the feeding end 300, thereby transporting the product tooling 100 to a position opposite to the output end of the second feeding cylinder 522. The second conveyor belt 512 extends along the X-axis and corresponds to the output end of the second feeding cylinder 522, so that after the output end of the second feeding cylinder 522 extends, it can push the product tooling 100 on the third conveyor belt 513 onto the second conveyor belt 512. The output end of the first feeding cylinder 521 is extendable along the Y-axis and is located at the output end of the second conveyor belt 512. The first conveyor belt 511 extends along the Y-axis, with its input end positioned opposite the output end of the first feeding cylinder 521. Its output end is connected to the housing 2. The pressurizing fixture mechanism 1 is located in the middle of the first conveyor belt 511, so that the product fixture 100 on the second conveyor belt 512 can be pushed onto the first conveyor belt 511 by the first feeding cylinder 521, and the pressing fixture 200 is stacked on the product fixture 100 on the first conveyor belt 511. Then, the fixture 400 to be baked is transported to the housing 2.

[0070] Further, refer to Figure 3 As shown, the feeding and conveying assembly 51 provided in this embodiment also includes a first conveying blocking drive 514 connected to the control mechanism. When the pressurizing fixture detection and feedback mechanism 4 detects that the product fixture 100 is in the first position, it sends a signal to the control mechanism so that the control mechanism can drive the first conveying blocking drive 514 to start. The output end of the first conveying blocking drive 514 can extend vertically and block the product fixture 100 to ensure that the product fixture 100 can be accurately positioned in the first position, thereby ensuring that the pressurizing fixture 200 can be accurately stacked on the product fixture 100.

[0071] Optionally, in order to protect the product tooling 100 and reduce the impact, a buffer pad 515 corresponding to the product tooling 100 is also provided on the output end of the first conveying blocking drive 514 along the Y-axis direction. The buffer pad 515 can be a polyurethane buffer pad to effectively reduce the impact force between the product tooling 100 and the output end of the first conveying blocking drive 514, thereby preventing the horn component 110 from loosening and falling off, and ensuring its installation stability.

[0072] Further, continue to refer to Figure 3As shown, in this embodiment, the product fixture 100 has a positioning hole; the feeding conveying assembly 51 also includes a lifting and positioning drive 516, which is located at the bottom of the first conveyor belt 511 and connected to the control mechanism. A positioning pin 5161 is provided on the output end of the lifting and positioning drive 516. When the product fixture 100 moves to the first work station, the control mechanism activates the first conveying blocking drive 514 and simultaneously activates the lifting and positioning drive 516, causing the output end of the lifting and positioning drive 516 to extend upwards in the vertical direction, thereby limiting and inserting the positioning pin 5161 into the positioning hole. Through the aforementioned lifting and positioning drive 516, the product fixture 100 can be fixed in the Y-axis direction, thereby further improving the stacking quality and accuracy of the pressurizing fixture 200.

[0073] Specifically, refer to Figure 4 As shown, the pressurizing fixture 1 includes a first support frame 11, a first pressurizing drive assembly 12, a second pressurizing drive assembly 13, and a first gripper 14. The first support frame 11 is fixedly mounted on a horizontal plane and located in the middle of the first conveyor belt 511. The first pressurizing drive assembly 12 includes a first slider 121, a first slide rail 122, and a first pressurizing drive component 123. Both the first pressurizing drive component 123 and the first slide rail 122 are fixedly mounted on the first support frame 11. The output end of the first pressurizing drive component 123 is connected to the first slider 121, allowing the first slider 121 to move along... Figure 4 The slider slides on the first slide rail 122 in the direction indicated by the X-axis. The second pressure-applying drive assembly 13 includes a second slider 131, a second slide rail 132, and a second pressure-applying drive member 133. The second pressure-applying drive member 133 and the second slide rail 132 are both fixedly arranged at the end of the first slider 121 in the vertical direction, and the output end of the second pressure-applying drive member 133 is connected to the second slider 131 so that the second slider 131 can slide on the second slide rail 132 in the vertical direction. The first gripper 14 is fixedly arranged on the second slider 131.

[0074] By setting the first pressure-releasing drive component 12, the first gripper 14 can cross the first station to pick up the pressure fixture 200 on the pressure fixture detection and feedback mechanism 4, and then move the picked-up pressure fixture 200 to a position relative to the first station, thereby ensuring the accuracy of the pressure fixture 200's stacking position. By setting the second pressure-releasing drive component 13, the pressure of the pressure fixture 200 stacking on the product fixture 100 can be controlled by controlling the distance of its vertical movement. This not only achieves consistency in stacking pressure but also facilitates adjustment of the stacking pressure, ensuring the safety and adhesion of the speaker components 110.

[0075] Optionally, the automatic pressure-maintaining hot air oven also includes an oven inlet mechanism 6, such as... Figure 5 As shown, it includes a support 61 and a feeding pusher 62. The support 61 is fixedly installed between the feeding conveying mechanism 5 and the housing 2, and a second sensor 611 connected to the control mechanism is fixedly installed thereon. The feeding pusher 62 is movably mounted on the support 61 along the direction of approaching or moving away from the inlet of the housing 2 (in this embodiment, the inlet and outlet of the housing 2 are along...). Figure 1 The feed pusher 62 is positioned along the Y-axis to allow it to move along the Y-axis and is connected to the control mechanism. When the first sensor 421 detects that the baking fixture 400 is in a preset position (i.e., the position relative to the entrance of the chamber 2), it sends a signal to the control mechanism to activate the feed pusher 62. At this time, the feed pusher 62 can push the baking fixture 400 into the chamber 2 for baking, thus realizing the process of automatically pushing the baking fixture 400 into the chamber 2, further improving the intelligent automation of the automatic pressure-holding hot air oven.

[0076] refer to Figure 6 As shown, multiple box panels 21 are fixedly arranged vertically inside the box body 2. For example, in this embodiment, five box panels 21 are provided to divide the box body 2 into five baking areas 22 (only one baking area 22 is shown in the figure). In addition, the oven feeding mechanism 6 provided in this embodiment also includes a feeding lifting assembly 63, which includes a feeding lifting frame 631 and a feeding lifting platform 632. The feeding lifting frame 631 is fixedly installed vertically between the support 61 and the entrance of the box 2. The feeding lifting platform 632 can slide on the feeding lifting frame 631 through the driving of the feeding lifting drive component 633. The feeding lifting platform 632 can receive the baking fixture 400 pushed out from the pressurizing fixture mechanism 3, and can be lifted sequentially on the feeding lifting frame 631 to the multi-layer baking area 22. The baking fixture 400 on the feeding lifting platform 632 is pushed into the corresponding baking area 22 by the feeding push component 62, thereby achieving the purpose of pushing multiple baking fixtures 400 into the baking areas 22 of different layers.

[0077] It should be noted that, in this embodiment, the product tooling 100 is along... Figure 2The length along the Y-axis is 280mm, and the total width along the X-axis is 98mm. Considering the actual dimensions of the speaker component 110 and the requirements of mass production, the product fixture 100 is designed with a one-outlet-four-outlet configuration, meaning that four speaker components 110 to be baked are spaced apart on the product fixture 100 to improve mass production efficiency. Correspondingly, four pressure clamps 210 are also fixed on the pressure fixture 200, so that the pressure clamps 210 are correspondingly set on the speaker components 110. Furthermore, by using an automatic pressure-holding hot air oven with a multi-layer baking zone 22 structure, the purpose of baking more speaker components 110 on the product fixture 100 can be achieved within a limited space, thereby further improving output and efficiency.

[0078] More specifically, see reference Figure 5 , Figure 7 As shown, the oven feeding mechanism 6 also includes a buffer platform 64, which is located between the output end of the first conveyor belt 511 and the entrance of the box 2, and is flush with the height of the output end of the first conveyor belt 511, so that the buffer platform 64 can receive and buffer the pushed-out baking fixture 400; in addition, the above-mentioned feeding pusher 62 includes a first pusher 621 and a plurality of second pushers 622, wherein the first pusher 621 is located at the bottom of the plurality of second pushers 622 in the vertical direction, the buffer platform 64 is correspondingly disposed on the first pusher 621, and the second pushers 622 are arranged at intervals in the vertical direction and are respectively disposed in the baking area 22.

[0079] For example, when the second sensor 611 detects that the baking fixture 400 is in a preset position, the control mechanism can control the first pusher 621 to start, so that the first pusher 621 can move along the direction close to the entrance of the box 2, thereby pushing the first set of baking fixtures 400 on the buffer platform 64 onto the feeding lifting platform 632. Then, the feeding lifting platform 632 first rises to the first baking area 22. The second pusher 622, which is corresponding to the first baking area 22, can then move along the direction close to the entrance of the box 2 to push the baking fixtures 400 on the feeding lifting platform 632 into the first baking area 22. Then the feeding lifting platform 632 descends again to the same height as the buffer platform 64. After the next set of baking fixtures 400 are in the preset position on the buffer platform 64, the first pusher 621 pushes the next set of baking fixtures 400 onto the feeding lifting platform 632. Then the feeding lifting platform 632 rises to the second baking area 22. The second pusher 622, which is corresponding to the second baking area 22, can move along the direction close to the entrance of the box 2 to push the baking fixtures 400 on the feeding lifting platform 632 into the second baking area 22. This process continues until all five baking areas 22 on the box 2 are equipped with baking fixtures 400.

[0080] The advantage of this setup is that when the feeding lifting platform 632 moves up and down and pushes the baking fixtures 400 into the chamber 2, multiple baking fixtures 400 in the same group can be temporarily stored on the buffer platform 64 instead of piling up on the first conveyor belt 511. This eliminates any obstruction to the rhythm of the next group of baking fixtures 400. After the feeding lifting platform 632 finishes sending the previous group of baking fixtures 400 into the corresponding baking area 22, it can descend to the same height as the buffer platform 64 and immediately receive the next group of baking fixtures 400 temporarily stored in the buffer platform 64. This avoids waiting for the next group of baking fixtures 400 to be pushed into the feeding lifting platform 632 one by one, ensuring that each group of baking fixtures 400 is pushed into the chamber 2 at regular intervals. This improves the orderly operation of the automatic pressure-holding hot air oven and ensures that the automatic pressure-holding hot air oven has higher production efficiency.

[0081] In this embodiment, to reduce the length occupied by the entire automatic pressure-holding hot air oven along the Y-axis, the pressurizing fixture mechanism 1 and the oven-feeding mechanism 6 are positioned on one side of the first conveyor belt 511 along the X-axis. Therefore, to ensure that the baking fixture 400 can be smoothly pushed into the oven body 2, in this embodiment, as shown... Figure 2As shown, the cylinder pushing assembly 52 also includes a third feeding cylinder 523, which is located between the buffer platform 64 and the output end of the first conveyor belt 511. The output end of the third feeding cylinder 523 is telescopically movable along the X-axis so that the third feeding cylinder 523 can push the baking fixture 400 located at the output end of the first conveyor belt 511 onto the buffer platform 64.

[0082] Furthermore, in this embodiment, to prevent the tooling 400 to be baked from falling off the first conveyor belt 511, the feeding and conveying assembly 51 further includes a second conveying blocking drive 517. The second conveying blocking drive 517 is vertically disposed at the output end of the first conveyor belt 511 and connected to the control mechanism. A vertical stop plate 5171 is fixed at the end of the output end of the second conveying blocking drive 517. When the tooling 400 to be baked is at the output end of the first conveyor belt 511, the control mechanism can activate the second conveying blocking drive 517, and the output end of the second conveying blocking drive 517 extends out to block the tooling 400 to be baked through the vertical stop plate 5171, thereby eliminating the safety hazard of the tooling 400 to be baked falling from the end of the output end of the first conveyor belt 511.

[0083] The specific structure of box 2 will be further explained below. (Reference) Figure 6 As shown, the housing 2 provided in this embodiment also includes a uniform heating element 23 and side plates 24. The uniform heating element 23 is fixedly installed at the bottom of the housing 2. Along the direction of movement perpendicular to the feeding pusher 62 (i.e., along the Y-axis), a side plate 24 is provided on each of the opposite sides of the housing 2. One side plate 24 has an air inlet channel and multiple air inlets, the air inlet channel being connected to the air outlet of the uniform heating element 23, and the air inlets being connected to the baking area 22. The other side plate 24 has an air outlet channel and multiple air outlets, the air outlet channel being connected to the air inlet of the uniform heating element 23, and the air outlets being connected to the baking area 22. In this way, the uniform heating element 23 (e.g., a hot air blower) allows hot air to circulate within the housing 2 (e.g.,...). Figure 6 (The direction of circulation indicated by the middle arrow) provides a similar or the same baking temperature for each baking zone 22, so that the baking temperature of each baking zone 22 can be stably maintained between, for example, 45° and 55°, to ensure the curing efficiency of the AB glue, save baking time, and also help reduce energy consumption costs.

[0084] Optionally, in this embodiment, a temperature display 25 is provided in each baking zone 22 so that those skilled in the art can observe the temperature changes of each baking zone 22 in real time, thereby facilitating management and temperature control.

[0085] Optionally, in this embodiment, combined with Figure 8 , Figure 9 As shown, the automatic pressure-holding hot air oven also includes an oven outlet mechanism 7, which includes an outlet lifting assembly 71, an outlet conveyor belt 72, and an outlet pushing component 73, all connected to the control mechanism. The outlet lifting assembly 71 includes an outlet lifting frame 711 and an outlet lifting platform 712. The outlet lifting frame 711 is vertically fixed between the outlet of the oven body 2 and the outlet conveyor belt 72, and the outlet lifting platform 712 can slide on the outlet lifting frame 711 under the driving action of the outlet lifting drive component 713. The input and output ends of the outlet conveyor belt 72 are respectively connected to the outlet lifting assembly 71 and the pressurizing fixture mechanism 3, and can transport the baked fixture 500. The outlet pushing component 73 is movably disposed within the oven body 2 in a direction closer to or farther from the outlet conveyor belt 72, and can push the baked fixture 500 on the outlet lifting platform 712 onto the outlet conveyor belt 72.

[0086] For example, after baking is completed, the material is first lifted by the discharge lifting platform 712 to the baking area 22 where the baking fixture 500 to be unloaded is located. Then, under the pushing action of the second feeding pusher 62, the baking fixture 400 on the feeding lifting platform 632 can push the baking fixture 500 in the baking area 22 onto the discharge lifting platform 712. At this time, the discharge lifting platform 712 descends, lowering the height of the baking fixture 500 to be consistent with the height of the discharge pusher 73. Then the discharge pusher 73 is activated, and the output end of the discharge pusher 73 extends and moves along the direction close to the discharge conveyor belt 72, thereby pushing the baking fixture 500 on the discharge lifting platform 712 onto the discharge conveyor belt 72. The baking fixture 500 is then transported to the pressure fixture removal mechanism 3 by the discharge conveyor belt 72, so that the pressure fixture 200 in the baking fixture 500 can be removed. With the above settings, the automatic pressure-holding hot air oven can achieve the beneficial effect of automatically unloading the baking fixture 500 and automatically transporting it to the pressurizing fixture 3 through the oven outlet mechanism 7, thereby further reducing human intervention and ensuring a stable and efficient production process.

[0087] It is particularly important to emphasize that, in this embodiment, as Figure 8 As shown, when the discharge pusher 73 is in the retracted state (i.e. not activated), it is stored in the position of the bottom baking area 22 of the box 2, so that the height of the discharge pusher 73 is lower than the bottom baking area 22. This allows the discharge pusher 73 to avoid each baking area 22 when it is activated and extended, preventing the discharge pusher 73 from interfering with or hindering the baking process in the multi-layer baking areas 22 during its movement.

[0088] Optionally, the oven discharge mechanism 7 provided in this embodiment further includes a tooling shifting component 74. The tooling shifting component 74 is movably disposed on the discharge lifting platform 712 along the Y-axis and is used to carry the baked tooling 500. After the baked tooling 500 is pushed onto the tooling shifting component 74 by the discharge pusher 73, the tooling shifting component 74 moves the baked tooling 500 a certain distance away from the outlet of the box 2 to avoid the exposed part of the tooling 400 to be baked inside the box 2. This avoids the situation where the baked tooling 500 collides with the tooling 400 to be baked inside the box 2 during the descent of the discharge lifting platform 712, thereby ensuring the safety of both the baked tooling 500 and the tooling 400 to be baked.

[0089] Optionally, combined Figure 1 , Figure 11 As shown, the oven discharge mechanism 7 provided in this embodiment also includes a conversion conveyor belt 75 and a conversion push drive 76, both connected to the control mechanism. The conversion conveyor belt 75 extends along the Y-axis direction, and its input end and output end are respectively connected to the output end of the discharge conveyor belt 72 and the pressurizing fixture mechanism 3. The output end of the conversion push drive 76 is retractable along the Y-axis direction and is located at the junction of the conversion conveyor belt 75 and the discharge conveyor belt 72. Under the pushing action of the conversion push drive 76, the baked fixture 500 on the discharge conveyor belt 72 can be transferred to the conversion conveyor belt 75 to continue moving until it moves to the position opposite to the pressurizing fixture mechanism 3 (i.e., the second station mentioned above). Thus, under the premise of satisfying the layout of each mechanism of the automatic pressure-holding hot air oven, it is ensured that the baked fixture 500 can be automatically transferred to the pressurizing fixture mechanism 3 for subsequent operation steps.

[0090] Specifically, in combination Figure 10 , Figure 11 As shown, the pressurizing fixture 3 provided in this embodiment includes a second support frame 31, a first pressurizing drive assembly 32, a second pressurizing drive assembly 33, and a second gripper 34. The second support frame 31 is fixedly mounted on a horizontal plane. The first pressurizing drive assembly 32 includes a third slider 321, a third slide rail 322, and a first pressurizing drive member 323. Both the first pressurizing drive member 323 and the third slide rail 322 are fixedly mounted on the second support frame 31. The output end of the first pressurizing drive member 323 is connected to the third slider 321, so that the third slider 321 can move along... Figure 3The component slides along the third slide rail 322 in the direction indicated by the X-axis. The second pressurizing drive assembly 33 includes a fourth slider 331, a fourth slide rail 332, and a second pressurizing drive member 333. Both the second pressurizing drive member 333 and the fourth slide rail 332 are fixedly disposed vertically at the end of the third slider 321, and the output end of the second pressurizing drive member 333 is connected to the fourth slider 331 so that the fourth slider 331 can slide vertically along the fourth slide rail 332. The second gripper 34 is fixedly disposed on the fourth slider 331. It should be noted that in this embodiment, the second station is also arranged parallel to the direction of movement of the pressurizing fixture 200 back to the pressurizing fixture release mechanism 1 along the X-axis. This can avoid the pressurizing fixture 200 from obstructing the movement of the product fixture 100 and realize the independent circulation of the return path of the pressurizing fixture 200.

[0091] By setting the first pressure-applying drive component 32 and the second pressure-applying drive component 33, the second gripper 34 can be adjusted to the actual clamping position along the X-axis and vertical directions respectively, so as to be positioned to the most accurate clamping position, prevent the pressure fixture 200 from being deformed and damaged due to clamping deviation, and thus improve the safety of the speaker component 110.

[0092] Furthermore, combined Figure 1 , Figure 12 and Figure 13 As shown, the oven discharge mechanism 7 provided in this embodiment also includes a feeding mechanism 8 connected to the control mechanism. The feeding mechanism 8 is located downstream of the pressurizing fixture mechanism 3 and can place the product fixture 100 after removing the pressurizing fixture 200 at the discharge end 600.

[0093] Specifically, in combination Figure 12 , Figure 13 As shown, the unloading mechanism 8 includes a tooling guide assembly 81 and an unloading assembly 82. The tooling guide assembly 81 includes a guide belt 811 and a straightening element 812. The input end of the guide belt 811 is connected to the output end of the conversion conveyor belt 75, and the output end of the guide belt 811 is connected to the discharge end 600, thereby achieving the purpose of moving the product tooling 100 on the conversion conveyor belt 75 closer to the discharge end 600. The straightening element 812 is disposed on the guide belt 811. The straightening element 812 includes a position sensor, an electric cylinder, and a positioning fixture. The position sensor can detect whether the product tooling 100 on the guide belt 811 has deviated in position. The electric cylinder can adjust and correct the position of the product tooling 100 by pushing, ensuring that the entire product tooling 100 can be placed on the guide belt 811. The positioning fixture can position the product tooling 100 to ensure that it maintains the correct position during transportation.

[0094] More specifically, in this embodiment, the unloading assembly 82 includes an unloading frame 821, a fifth slide rail 822, a fifth slider 823, a sixth slide rail 824, a sixth slider 825, and a third gripper 826. The unloading frame 821 is fixedly disposed on a horizontal plane; the fifth slide rail 822 extends along the Y-axis and is fixedly connected to the unloading frame 821 to achieve a docking connection with the discharge end 600 extending along the Y-axis; the fifth slider 823 is slidably disposed on the fifth slide rail 822 along the Y-axis; the sixth slide rail 824 is fixedly connected to the fifth slider 823 in the vertical direction; the sixth slider 825 is slidably disposed on the sixth slide rail 824 in the vertical direction; and the third gripper 826 is fixedly connected to the sixth slider 825. The unloading mechanism 8, which is connected to the control mechanism, can not only ensure that the product tooling 100 can be safely and stably transferred to the discharge end 600 along the Y-axis through the unloading component 82, but also achieve the purpose of automatically transferring the product tooling 100 to the discharge end 600, thereby further reducing human intervention and greatly alleviating the work pressure of the staff.

[0095] The pressurization fixture detection feedback mechanism 4 provided in this embodiment will be described in detail below. Specifically, refer to... Figure 14 As shown, the pressure fixture testing and feedback mechanism 4 includes a feedback belt assembly 41 and a testing component, both connected to the control mechanism. The input and output ends of the feedback belt assembly 41 are respectively connected to the pressure fixture taking mechanism 3 and the pressure fixture placing mechanism 1, and are used to carry the pressure fixture 200. The testing component can detect the actual position of the product fixture 100.

[0096] In practical use, after the pressurizing fixture mechanism 3 places the pressurizing fixture 200 on the return belt assembly 41, the return belt assembly 41 can carry the pressurizing fixture 200 back to the direction close to the pressurizing fixture 200 mechanism. When the detection piece is detected on the pressurizing fixture 200, the first gripper 14 on the pressurizing fixture mechanism 1 can automatically move sequentially along the X-axis and vertical direction under the action of the control mechanism, thereby obtaining the pressurizing fixture 200 on the return belt assembly 41. Then it moves in the opposite direction and carries the pressurizing fixture 200 to be located directly above the first conveyor belt 511 for stacking on the product fixture 100.

[0097] For more details, please refer to [link / reference]. Figure 14As shown, the detection component includes a first sensor 421, which is disposed at the output end of the return belt assembly 41. Furthermore, the pressurizing fixture detection return mechanism 4 also includes a first blocking interval sensing drive 43. Along the extending direction of the return belt assembly 41, the first blocking interval sensing drive 43 is disposed upstream of the first sensor 421, and its output end is capable of extending and retracting vertically. When the first sensor 421 detects that the pressurizing fixture 200 on the return belt assembly 41 is in a first designated position, the first sensor 421 sends a start signal to the first blocking interval sensing drive 43, causing the output shaft of the first blocking interval sensing drive 43 to extend and abut against the return belt assembly 41. Since the return belt assembly 41 is equipped with multiple pressure fixtures 200, the first blocking interval sensing drive 43 ensures that adjacent pressure fixtures 200 maintain a certain distance, such as 20mm, to prevent the first gripper 14 from lifting the next pressure fixture 200, or to avoid the situation where two adjacent pressure fixtures 200 are squeezed together, preventing the previous pressure fixture 200 from being gripped by the first gripper 14. It should be noted that the first designated position at this time indicates that the pressure fixture 200 is located near the output end of the return belt assembly 41.

[0098] More specifically, the pressurizing fixture detection and feedback mechanism 4 also includes a second blocking interval sensing drive 44. Along the extending direction of the feedback belt assembly 41, the second blocking interval sensing drive 44 is positioned upstream of the first blocking interval sensing drive 43 and is signal-connected to the first blocking interval sensing drive 43. In practical use, when the first blocking interval sensing drive 43 detects that the pressurizing fixture 200 on the feedback belt assembly 41 is in a second designated position, the first blocking interval sensing drive 43 sends a start signal to the second blocking interval sensing drive 44, allowing the output shaft of the second blocking interval sensing drive 44 to extend and abut against the feedback belt assembly 41. This allows the pressurizing fixtures 200 located at both ends of the second blocking interval sensing drive 44 to be spaced apart, ensuring that every two adjacent pressurizing fixtures 200 on the entire feedback belt assembly 41 are separated by a distance, preventing the pressurizing fixtures 200 from being squeezed or bumped. It should be noted that the second designated position at this time means that the pressure fixture 200 is located close to the surface of the first blocking interval sensing drive 43 relative to the second blocking interval sensing drive 44.

[0099] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
