Description

Technical Field

[0001] The utility model relates to the technical field of solar cell production, in particular to a drying device with stable transmission. Background Art

[0002] In the field of solar silicon wafer manufacturing, drying of solar cells is one of the most important steps, and a cassette drying furnace is one of the important devices to complete the drying step. Generally, a cassette drying furnace includes a drying chamber composed of several drying modules, and a carrier (such as a flower basket or a flower basket boat) loaded with solar cells is transmitted through the drying chamber by a transmission device. However, since the carrier is usually directly placed on the transmission device, during the transmission of the carrier by the transmission device, the carrier is prone to tilt and shake, which may cause the solar cells on the carrier to deviate from their established positions, and there is a possibility of falling off or even fragmenting. Summary of the Utility Model

[0003] To overcome the above disadvantages, the purpose of the utility model is to provide a drying device with stable transmission, which can improve the stability of the carrier during transmission by locking the carrier, thereby effectively reducing the risk of falling off and fragmenting of solar cells during transmission.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a drying device with stable transmission, including at least one drying furnace arranged side by side; each of the drying furnaces includes

[0005] a furnace body, on which a product channel is provided, one end of the product channel is a product inlet, and the other end is a product outlet;

[0006] a transmission mechanism for transmitting the product in the product channel; the transmission mechanism penetrates through the product channel, and a carrier for loading the product is provided thereon;

[0007] a locking mechanism arranged on the transmission mechanism, which includes a plurality of locking parts arranged on the transmission mechanism along the product conveying direction, and the locking parts are used to lock the carrier on the transmission mechanism;

[0008] an unlocking mechanism arranged at least at the product outlet for unlocking the locking of the carrier by the locking mechanism.

[0009] The beneficial effect of the drying device of the utility model is as follows:

[0010] During the transmission of the carrier loaded with the product along the product channel by the transmission mechanism, the locking part of the locking mechanism can lock the carrier on the transmission mechanism to improve the stability of the carrier on the transmission mechanism and suppress the tilt and shake phenomenon of the carrier during transmission; an unlocking mechanism is arranged at the product outlet to unlock the locking between the carrier and the transmission mechanism, thereby facilitating the removal of the carrier from the transmission mechanism.

[0011] Further, the locking portion includes locking members symmetrically arranged on both sides of the carrier in a direction perpendicular to the product conveying direction, each of the locking members includes a locking block, an elastic member, and a movable member, the movable member can move along the transmission mechanism in a direction close to or away from the carrier, the locking block is connected to a side of the movable member facing the carrier; the elastic member is located at an end of the locking block away from the carrier, one end of the elastic member abuts against the locking block, and the other end is fixed to the transmission mechanism; and when the locking block abuts against the carrier, the elastic member is in a compressed state.

[0012] The movement of the moving parts of the two locks can simultaneously drive the two locking blocks to move towards or away from the carrier, thereby achieving locking or unlocking of the carrier; and the elastic parts in a compressed state are arranged so that the locking blocks can be elastically pressed against the carrier, which not only ensures the locking of the carrier, but also avoids damage to the surface of the carrier caused by rigid pressure.

[0013] Furthermore, the lock member further comprises a mounting seat, the mounting seat is fixedly connected to the transmission mechanism, and a guide slot is provided therethrough; the moving member comprises a pull rod provided in the guide slot, and one end of the pull rod facing the carrier is connected to the locking block. The moving direction of the pull rod can be guided by the mounting seat and the guide slot, thereby ensuring the accuracy of the locking direction of the locking block.

[0014] Furthermore, the elastic member includes a spring sleeved on the pull rod, one end of the spring abuts against the locking block, and the other end abuts against the mounting seat. Since the mounting seat is fixed to the transmission mechanism, when an external force pulls the pull rod to move away from the carrier, the locking block can move synchronously, thereby compressing the spring; and when the external force is removed, the locking block can move toward the carrier under the resetting action of the spring.

[0015] Furthermore, the upper end of the mounting seat is provided with a waist-shaped groove connected to the guide groove; the pull rod is fixed with a vertical rod that can be inserted into the waist-shaped groove. The waist-shaped groove can limit the movement range of the vertical rod, thereby indirectly limiting the movement range of the pull rod.

[0016] Furthermore, a locking protrusion is provided on the side of the locking block facing the carrier; when the locking block abuts against the carrier, the lower end surface of the locking protrusion also abuts against the carrier; the lower end surface of the locking protrusion is a downwardly arched arc surface. The provision of the locking protrusion can cooperate with the locking block to abut against the carrier at multiple points and in different directions, so as to enhance the locking stability of the carrier. At the same time, by setting the lower end surface of the locking protrusion as a downwardly arched arc surface, the contact between the locking protrusion and the carrier is a line contact, thereby reducing the friction between the locking protrusion and the carrier as much as possible.

[0017] Furthermore, the unlocking mechanism includes unlocking members symmetrically arranged on the transmission mechanism along a direction perpendicular to the product conveying direction. Each unlocking member includes a plate body arranged along the product conveying direction. The plate body is suspended on the transmission mechanism, and an unlocking surface capable of pressing against the moving member is provided on the side away from the carrier. When the carrier moves to the unlocking mechanism, the moving member can move away from the carrier under the action of the abutting surface, so that the locking block disengages from the carrier. The movement of the moving member away from the carrier can be forced by the limiting abutment of the unlocking surface, and then the locking block disengages from the carrier, realizing the unlocking of the carrier.

[0018] Furthermore, the abutting surface includes an unlocking inclined surface and a pressing plane continuously arranged along the product transmission direction. The unlocking inclined surface gradually inclines away from the carrier from one end away from the pressing plane to one end close to the pressing plane, so that when the vertical rod moves along the unlocking inclined surface towards the pressing inclined surface, the vertical rod can drive the locking block to move away from the carrier. The setting of the unlocking inclined surface enables the moving member to move away from the carrier along the unlocking inclined surface when the moving member moves to the unlocking inclined surface along with the transmission mechanism, thereby realizing the unlocking of the carrier by the locking block. When the moving member enters the pressing plane along the unlocking inclined surface, due to the pressing and limiting of the moving member by the pressing plane, the locking block is always in the state of unlocking the carrier, so as to ensure that the carrier can be taken out from the transmission mechanism when the carrier moves to the pressing plane.

[0019] Furthermore, the plate body is bent downward at one end away from the unlocking inclined surface to form a bent plate. A guiding surface is provided on the side of the bent plate away from the carrier. The guiding surface includes a continuously arranged guiding plane and a guiding inclined surface. The guiding plane is located between the guiding inclined surface and the pressing plane, and the guiding plane and the pressing plane are in the same plane. The guiding inclined surface gradually inclines towards the carrier from one end close to the guiding plane to one end away from the guiding plane.

[0020] When the vertical rod moves along the plate body towards the bent plate, the vertical rod can sequentially enter the guiding plane and the guiding inclined surface along the pressing plane. When the vertical rod presses against the guiding inclined surface, under the resetting action of the spring and the guiding action of the guiding inclined surface, the locking block can gradually move towards the carrier, thereby buffering the resetting action of the locking member.

[0021] Furthermore, the furnace body is sequentially provided with a drying area and a cooling area along the product transmission direction. A heating module for heating the product channel is provided in the drying area. The heating module is a single-cycle heating module or a double-cycle heating module. The product in the product channel can be heated and dried by the setting of the heating module.

[0022] Furthermore, a carrier return mechanism for transporting the carrier is provided below the furnace body, and a lifting mechanism for lifting the carrier onto the product mechanism is provided between the product transport mechanism and the carrier return mechanism near the product inlet.

[0023] When the product enters the next process from the product outlet, the carrier return mechanism can return the carrier at the product outlet to the product inlet, and then the lifting mechanism lifts the carrier on the carrier return mechanism onto the product transport mechanism to facilitate loading the next product.

[0039] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0040] Embodiment

[0041] See the attached Figures 1-3 As shown, a drying device with stable transmission of the present utility model includes at least one drying furnace arranged side by side; each drying furnace includes a furnace body 1, a transmission mechanism 2, a locking mechanism 3, and an unlocking mechanism 4. Among them, a product passage 11 is provided on the furnace body 1, one end of the product passage 11 is a product inlet, and the other end is a product outlet. The transmission mechanism 2 is arranged through the product passage 11 for transmitting the product in the product passage 11, and a vehicle 5 for loading the product is provided on the transmission mechanism 2. The locking mechanism 3 is arranged on the transmission mechanism 4, and it includes a plurality of locking parts arranged on the transmission mechanism 2 along the product conveying direction, and the locking parts are used to lock the vehicle 5 on the transmission mechanism 2. The unlocking mechanism 4 is arranged at least at the product outlet for unlocking the locking of the vehicle 5 by the locking mechanism 3.

[0042] During the process of the vehicle 5 carrying the product being transmitted along the product passage 11 by the transmission mechanism 2, the locking parts of the locking mechanism 3 can lock the vehicle 5 on the transmission mechanism 2 to improve the stability of the vehicle 5 on the transmission mechanism 2 and suppress the tilting and jitter phenomenon of the vehicle 5 during transmission; an unlocking mechanism 4 is provided at the product outlet to unlock the locking between the vehicle 5 and the transmission mechanism 2, thereby facilitating the removal of the vehicle 5 from the transmission mechanism 2.

[0043] In some embodiments, see the attached Figure 3 As shown, the transmission mechanism 2 includes a driving roller and a driven roller installed on a transmission rack 21. Two closed-loop chains 22 arranged side by side are jointly wound around the driven roller and the driving roller, and a plurality of support plates 23 for receiving the vehicle 5 are evenly arranged between the two closed-loop chains 22 along the product transmission direction. And a transmission driving member 24 connected to the driving roller is provided on the installation rack 21. When the transmission driving member 24 is started, the driving roller rotates accordingly, drives the two closed-loop chains 22 to synchronously transmit, and the driven roller rotates immediately. At this time, the vehicle located on the support plate 23 is transmitted along the product passage 11.

[0044] Further, the transmission driving member 24 includes a driving motor mounted on the transmission frame 21, and the driving motor is connected to the driving roller through a synchronous chain group to improve the running stability of the driving roller.

[0045] It should be noted that the structure of the transmission mechanism 2 can adopt the existing technology, and only needs to realize the transmission of the carrier 5 and the product along the product channel 11. The locking mechanism 3 and the unlocking mechanism 4 will be specifically described below.

[0046] In some embodiments, see the appendix Figures 4-7 As shown, the locking part includes locking members symmetrically arranged on both sides of the carrier 5 along the direction perpendicular to the product conveying direction. Each locking member includes a locking block 31, an elastic member 32, and a moving member 33. Among them, the moving member 33 can move along the transmission mechanism 2 in a direction close to or away from the carrier 5, and the locking block 31 is connected to the side of the moving member 33 facing the carrier 5. The elastic member 32 is located at one end of the locking block 31 away from the carrier 5. One end of the elastic member 32 abuts against the locking block 31, and the other end is fixed on the transmission mechanism 2; and when the locking block 31 abuts against the carrier 5, the elastic member 32 is in a compressed state.

[0047] Since the locking part is arranged on the transmission mechanism 2, it can be synchronously transmitted with the product and the carrier 5 during the transmission of the product and the carrier 5; in the locking part, along the direction perpendicular to the product conveying direction, the cooperation of the two locking members can make the two locking blocks 31 move in the direction close to or away from the carrier 5 at the same time, so as to realize the limit locking or unlocking of the carrier 5 during transmission; and through the arrangement of the elastic member 32 in a compressed state, the locking block 31 can elastically press against the carrier 5, which not only ensures the locking of the carrier 5, but also avoids damage to the surface of the carrier 5 caused by rigid pressing.

[0048] It should be noted that in this embodiment, the direction of approaching or departing from the carrier refers to approaching or departing from the carrier along the direction perpendicular to the product conveying direction. For the number setting of the locking parts, it can be the same as the number of the support plates 23, and the locking parts are arranged on the support plates 23 one by one, or the number of the support plates 23 can be several times greater than the number of the locking parts, and several locking parts are evenly spaced on several support plates 23. No matter how the number of the locking parts is set, it is necessary to ensure that the distance between two adjacent locking parts is less than the size of the carrier 5 in the product transmission direction, so that when the carrier 5 is placed on the transmission mechanism 2, at least one locking part can lock the carrier 5.

[0049] In some embodiments, see the appendix Figure 5 、 7As shown, the locking member further includes a mounting base 34, which is fixedly mounted on the support plate 23 and is provided with a guiding through groove arranged along a direction perpendicular to the product conveying direction. The moving member 33 includes a pull rod 331 inserted into the guiding through groove, and one end of the pull rod 331 (along the direction perpendicular to the product conveying direction) facing the carrier 5 is connected to the locking block 31. The locking block 31 is suspended, and the end thereof away from the pull rod 331 is used to abut against the carrier 5.

[0050] The arrangement of the mounting base 34 and the guiding through groove can guide the moving direction of the pull rod 331, thereby ensuring the accuracy of the locking direction of the locking block 31; the suspension arrangement of the locking block 31 can reduce the contact between the locking block 31 and the support plate 23 during the movement, thereby reducing the moving resistance.

[0051] Furthermore, as shown in the appendix Figure 5 As shown, the elastic member 32 includes a spring sleeved on the pull rod 331. One end of the spring abuts against the locking block 31, and the other end abuts against the mounting base 34. Since the mounting base 34 is fixedly connected to the transmission mechanism 2, when an external force pulls the pull rod 331 to move away from the carrier 5, the locking block 31 can move synchronously, thereby compressing the spring; when the external force is withdrawn, under the reset action of the spring, the locking block 31 can move towards the carrier 5 to lock the carrier 5.

[0052] In order to ensure that the spring is always in a compressed state, it is necessary to limit the moving ranges of the pull rod 331 and the locking block 31. In some embodiments, as shown in the appendix Figure 7 As shown, a waist-shaped groove 341 communicating with the guiding through groove is formed at the upper end of the mounting base 34. A vertical rod 332 that can be inserted into the waist-shaped groove 341 is fixedly arranged on the pull rod 331. When the vertical rod 332 moves in the waist-shaped groove 341, the spring is always in a compressed state. And when the vertical rod 332 moves to the end of the waist-shaped groove 341 close to the carrier 5, the locking block 31 can lock the carrier 5, while when the vertical rod 332 moves to the end of the waist-shaped groove 341 away from the carrier 5, the locking block 31 cannot lock the carrier 5. The arrangement of the waist-shaped groove 341 can limit the moving range of the vertical rod 332, thereby indirectly limiting the moving ranges of the pull rod 331 and the locking block 31.

[0053] The locking block 31 locks the carrier 5 from the side of the carrier 5, which can effectively prevent the carrier 5 from tipping over, but has a poor locking effect on the forward or backward tipping of the carrier 5. Based on this, in order to enhance the locking effect on the carrier 5, in some embodiments, a locking convex portion 311 is provided on the side of the locking block 31 facing the carrier 5. When the locking block 31 abuts against the side of the carrier 5, the lower end surface of the locking convex portion 311 can also abut against the carrier 5, thereby forming a vertical restriction on the carrier 5 to cooperate with the locking block 31 to form a multi-point locking of the carrier 5 and enhance the locking stability of the carrier 5.

[0054] Further, the lower end surface of the locking convex portion 311 is an arc surface that arches downward. So that the contact between the locking convex portion 311 and the carrier 5 is a line contact, and the contact friction between the locking convex portion 311 and the carrier 5 is reduced as much as possible.

[0055] In some embodiments, referring to the attached Figure 5 、 7 As shown, the unlocking mechanism 4 includes unlocking members symmetrically arranged on the transmission mechanism 2 along a direction perpendicular to the product conveying direction. Each unlocking member includes a plate body 41 arranged along the product conveying direction. The plate body 41 is fixedly connected to the transmission frame 21 and is suspended above the support plate 23. An unlocking surface capable of pressing against the vertical rod 332 is provided on the side of the plate body 41 away from the carrier 5. Specifically, the unlocking surface includes an unlocking inclined surface 411 and a pressing plane 412 that are continuously arranged along the product transmission direction. The unlocking inclined surface 411 is located at one end of the pressing plane 412 away from the product outlet, and the unlocking inclined surface 411 gradually inclines away from the carrier 5 from one end away from the pressing plane 412 to one end close to the pressing plane 412. So that when the vertical rod 332 moves along the unlocking inclined surface 411 towards the pressing plane 412, the vertical rod 332 can drive the locking block 31 to move away from the carrier 5.

[0056] In actual setting, the height of the lower end surface of the plate body 41 should be higher than the height of the upper end surface of the mounting seat 34 to ensure that the mounting seat 34 can pass through below the plate body 41 when the vertical rod 332 moves along the unlocking surface of the plate body 41. In addition, in order to ensure that the vertical rod 332 can smoothly abut against the unlocking inclined surface 411, the end of the unlocking inclined surface 411 away from the pressing plane 412 should be set to be closer to the carrier 5 than the vertical rod 332 in the locked state (in the locked state, the locking block 31 presses against the carrier 5 and the vertical rod 332 is located at one end of the kidney-shaped groove 341 close to the carrier 5). When the vertical rod 332 in the locked state moves to the unlocking member, the vertical rod 332 can directly abut against the unlocking inclined surface 411, and during the movement of the mounting seat 34 along with the transmission mechanism 2, the vertical rod 332 can move along the unlocking inclined surface 411, thereby driving the locking block 31 to move away from the carrier 5. When the vertical rod 332 moves to the junction of the unlocking inclined surface 411 and the pressing plane 412, the vertical rod 332 can move to one end of the kidney-shaped groove 341 away from the carrier 5. At this time, the locking block 31 no longer abuts against the carrier 5, and the carrier 5 is in an unlocked state.

[0057] The pressing plane 412 is always a plane along the product transmission direction. After the vertical rod 332 moves along the unlocking inclined surface 411 to the pressing plane 412, the vertical rod 332 always presses against the pressing plane 412 to ensure that the locking block 31 always remains in a state of not abutting against the carrier 5.

[0058] Further, referring to the attachedFigure 7 As shown in the figure, the vertical rod 332 includes a rod body integrally formed with the pull rod 331. A rotatable protective sleeve 3321 is sleeved on the rod body, and the outer diameter of the protective sleeve 3321 is slightly larger than the outer diameter of the rod body. When the vertical rod 332 moves to the unlocking surface, the protective sleeve 3321 can abut against the unlocking surface. Through the cooperation between the protective sleeve 3321 and the rod body, the friction between the vertical rod 332 and the unlocking surface can be adjusted to rolling friction, thereby reducing the frictional resistance between the vertical rod 332 and the unlocking surface.

[0059] Since the transmission mechanism 2 is in a closed-loop shape, during the transmission of the closed-loop chain 22, the support plate 23 and the locking portion that move to the product outlet can flow back to the product inlet again. At this time, the locking portion is no longer affected by the unlocking mechanism at the product outlet, and the locking block 31 can be reset to the locked state under the action of the spring. In order to avoid the violent collision of the vertical rod 332 in the kidney-shaped groove 341 caused by the too-fast reset of the locking block 31, in some embodiments, one end of the plate body 41 away from the unlocking inclined surface 411 is bent downward to form a bent plate 42 that matches the shape of the transmission mechanism 2 at the product outlet. A guiding surface is provided on the side of the bent plate 42 away from the carrier 5. The guiding surface includes a continuously arranged guiding plane and a guiding inclined surface 421. Among them, the guiding plane is located between the guiding inclined surface 421 and the pressing plane 412, and the guiding plane and the pressing plane 412 are on the same plane. The guiding inclined surface 421 gradually inclines towards the carrier 5 from the end close to the guiding plane to the end away from the guiding plane.

[0060] When the vertical rod 332 moves along the plate body 41 towards the bent plate 42, the vertical rod 332 can sequentially enter the guiding plane and the guiding inclined surface 421 along the pressing plane 412. And when the vertical rod 332 abuts against the guiding inclined surface 421, under the resetting action of the spring and the guiding action of the guiding inclined surface 421, the locking block 31 can gradually move towards the carrier 5. Through the setting of the bent plate 42, the resetting action of the locking member can be buffered.

[0061] In some embodiments, an unlocking mechanism 4 can also be provided at the product inlet. However, the setting direction is different from that at the product inlet. At the product inlet, as the transmission mechanism 2 transmits, the vertical rod 332 first contacts the pressing plane 412 of the unlocking mechanism 4 and then contacts the unlocking inclined surface 411 of the unlocking mechanism 4. While at the product outlet, the vertical rod 332 first contacts the unlocking inclined surface 411 of the unlocking mechanism 4 and then contacts the pressing plane 412 of the unlocking mechanism 4.

[0062] In some embodiments, refer to the attached Figure 6As shown in the figure, the furnace body 1 is successively provided with a drying area and a cooling area along the product transmission direction. A heating module 6 for heating the product channel 11 is arranged in the drying area. The heating module 6 is a single-cycle heating module or a double-cycle heating module. By setting the heating module 6, the products in the product channel 11 can be heated and dried.

[0063] Among them, the single-cycle heating module is a heating chamber 61 with a single built-in heating element arranged on one side of the furnace body 1, and the circulation fan 62 is used to realize the circulation of the air flow between the heating chamber 51 and the product channel 11. The double-cycle heating module is a heating chamber 61 with built-in heating elements arranged on both sides of the furnace body 1, and each heating chamber 61 realizes the air flow circulation with the product channel 11 through an independent circulation fan 62.

[0064] When the product flows from the product outlet to the next process, the empty carrier 5 will stay on the transmission mechanism 2. In order to recycle or temporarily store the empty carrier 5, in some embodiments, a carrier return mechanism 7 for transmitting the carrier 5 is arranged below the furnace body 1. Specifically, the carrier return mechanism 7 includes a return rack 71. The return rack 71 is arranged along the product transmission direction, and its two ends respectively extend to the lower parts of the product inlet and the product outlet of the product channel 11. And a linear transmission module 72 is arranged on the return rack 71.

[0065] During use, when the product flows from the product outlet to the next process, the empty carrier 5 will stay at the product outlet. At this time, by placing the empty carrier 5 on the linear transmission module 72 of the return rack 71, the temporary storage operation of the empty carrier 5 can be realized; and when the carrier 5 is needed at the product inlet, the empty carrier 5 can be re-circulated to the product inlet side through the linear transmission module 72.

[0066] Due to the height difference between the carrier return mechanism 7 and the transmission mechanism 2, in some embodiments, a lifting mechanism for lifting the carrier 5 onto the transmission mechanism 2 is arranged between the transmission mechanism 2 near the product inlet and the carrier return mechanism 7.

[0067] When the product enters the next process from the product outlet, through the setting of the carrier return mechanism 7, the carrier 5 at the product outlet can be re-circulated to the product inlet, and then the lifting mechanism is used to lift the carrier 5 on the carrier return mechanism 7 onto the transmission mechanism 2, so as to facilitate the loading of the next product.

[0068] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and its purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
