Description

Technical Field

[0001] The present application relates to the technical field of degreasing and sintering devices, and more specifically, to a bracket and a degreasing and sintering device. Background Art

[0002] Existing degreasing and sintering devices usually include a degreasing and sintering furnace, which can be a single furnace or multiple furnaces such as a degreasing furnace and a sintering furnace. To improve the degreasing and sintering efficiency, during the degreasing and sintering process, multiple materials need to be stacked one by one in the degreasing and sintering furnace, and then the degreasing and sintering furnace is started to complete the degreasing and sintering work of multiple materials at one time.

[0003] Since the existing technology requires manual continuous handling of materials and stacking of materials in the degreasing and sintering furnace, it is only possible to observe whether the materials are stacked neatly from the furnace mouth of the degreasing and sintering furnace, and it is impossible to observe the materials from the side, which easily leads to the materials not being placed in the preset position, affecting the temperature uniformity of degreasing and sintering, and thus reducing the yield; at the same time, it takes a long time to put the materials into and take them out of the degreasing and sintering furnace, resulting in low degreasing and sintering efficiency of the degreasing and sintering device.

[0004] In summary, when the existing degreasing and sintering device processes multiple materials at one time, its degreasing and sintering efficiency is low and the yield is low. Summary of the Invention

In addition, whenever a numerical range is indicated herein, it means including any cited number (fraction or integer) within the indicated range.

[0038] Please refer to Figures 1 to 2 , a bracket for transporting material 10, the bracket comprising:

[0039] A main body 200;

[0040] A plurality of first rolling components 210, the first rolling components 210 being connected to the main body 200 and configured to rotate at a fixed point in at least one direction to at least support the material 10 and allow the material 10 to move along the surface of the first rolling components 210.

[0041] In this embodiment, first of all, the first rolling components 210 can rotate at a fixed point in at least one direction, and this direction can be set as Figure 1 the Y direction in. When the material 10 is placed on the first rolling components 210 and pushed by the user (in the Y direction in the figure), the first rolling components 210 will also roll. Therefore, a rolling contact is presented between the material 10 and the first rolling components 210, the frictional force is small, and the force required is also small. Compared with manually placing the materials 10 one by one into the degreasing sintering furnace 100, the embodiment of the present application can first stack a plurality of materials 10 on the bracket, and then push the materials 10 into the degreasing sintering furnace 100 by means of the first rolling components 210, that is, the degreasing sintering efficiency is effectively improved. Similarly, when pulling the material 10 out of the degreasing sintering furnace 100, the material 10 can also be pulled out at one time, thereby improving the unloading speed of the material 10.

[0042] Secondly, compared with the prior art where the materials 10 are stacked in the degreasing sintering furnace 100 and the stacking situation of the materials can only be observed from the Y direction, the bracket of the embodiment of the present application enables the user to first stack a plurality of materials 10 on the first rolling components 210 of the bracket, and then observe whether the materials 10 are stacked neatly and meet the expectations from all around the bracket, thereby avoiding uneven degreasing and sintering of some of the materials 10 and further improving the finished product rate of degreasing and sintering. It should be understood that the first rolling components 210 can be at least one of ball bearings, rolling bearings, rollers, and conveyor tracks.

[0043] Furthermore, please refer to Figures 1 to 3 , the bracket further includes a pallet 300, the first rolling components 210 are located between the main body 200 and the pallet 300, and the pallet 300 is used to support the material 10;

[0044] The first rolling components 210 are used to support the pallet 300 and allow the pallet 300 to move along the surface of the first rolling components 210.

[0045] In this embodiment, if multiple materials 10 directly contact the first rolling component 210 after being stacked, since the contact area between the first rolling component 210 and the materials 10 is small, it may cause deformation at the bottom of the materials 10 directly contacting the first rolling component 210, or the bottom of the materials 10 may be unevenly stressed and dispersed, unable to maintain a neat stacked shape, thus resulting in a low yield of degreasing and sintering. It should be understood that the pallet 300 can be a plate-like structure or a box-like structure. When the pallet 300 is a box-like structure, the materials 10 can be accommodated by the box-like pallet 300, thereby preventing the materials 10 from being dispersed.

[0046] Because this embodiment is provided with the pallet 300, multiple materials 10 can be stacked on the pallet 300, and then the pallet 300 directly contacts the first rolling component 210, thereby preventing deformation at the bottom of the materials 10 and the dispersion of the materials 10, and further improving the yield of degreasing and sintering. At the same time, when it is necessary to transfer multiple materials 10, the user can directly move the pallet 300, avoiding touching the materials 10 and causing the materials 10 to be dispersed and requiring re-stacking, thereby improving the transfer efficiency of the materials 10.

[0047] Further, please refer to Figures 3 to 4 , the pallet 300 is provided with a supporting surface and a plurality of ventilation holes 310. The supporting surface is used to carry the materials 10, and the ventilation holes 310 are arranged on the supporting surface and penetrate through the pallet 300.

[0048] In this embodiment, during the degreasing and sintering process, it is necessary to ensure that all surfaces of the materials 10 are heated and baked evenly. At the same time, to improve efficiency, when the user pushes the materials 10 into the degreasing and sintering furnace 100, the pallet 300 should enter the degreasing and sintering furnace 100 together with the materials 10. Therefore, during the degreasing and sintering process, the pallet 300 will block the bottom of the materials 10 to a certain extent, affecting the heating and baking efficiency of the bottom of the materials 10, and thus reducing the yield of degreasing and sintering.

[0049] The pallet 300 of this embodiment is provided with ventilation holes 310. Therefore, after the pallet 300 and the materials 10 are both located in the degreasing and sintering furnace 100, the ventilation holes 310 can allow the internal hot air flow to enter, and at the same time enable the bottom of the materials 10 to directly contact the baking high temperature, thereby making all surfaces of the materials 10 heated evenly, and further improving the yield of degreasing and sintering. It should be understood that, when the pallet 300 meets the structural strength for placing the materials 10, the ratio of the total area of the ventilation holes 310 to the area of the supporting surface should be as large as possible. It should be understood that, please refer to Figure 2 , holes can also be opened on the main body 200 to facilitate the heat dissipation of the materials 10 after being pulled out of the degreasing and sintering furnace 100.

[0050] Further, please refer to Figures 2 to 3, the main body 200 is provided with a first baffle 201, a second baffle 202 and a third baffle 203. The first baffle 201, the second baffle 202 and the third baffle 203 enclose a first accommodation cavity (not marked in the figure) and an opening (not marked in the figure) opposite to the second baffle 202. The first rolling assembly 210 is located in the first accommodation cavity and can roll towards the opening direction.

[0051] In this embodiment, since the first rolling assembly 210 is located in the first accommodation cavity, when the material 10 or the pallet 300 is placed in contact with the first rolling assembly 210, at least part of the material 10 or the pallet 300 is also located in the accommodation cavity. That is, the first baffle 201, the second baffle 202 and the third baffle 203 will play a role in blocking the material 10 or the pallet 300 from moving in the opposite directions of the X direction and the Y direction, thereby preventing the material 10 or the pallet 300 from slipping towards the directions where the first baffle 201, the second baffle 202 and the third baffle 203 are located. At this time, the material 10 or the pallet 300 can only move in the Y direction shown in the figure. It should be understood that the shape of the pallet 300 can be adapted to the first accommodation cavity. For example, when the first accommodation cavity is rectangular, the shape of the pallet 300 is square, and the diagonal length of the square is less than the width (X direction) of the first accommodation cavity, thereby preventing the pallet 300 from rotating around the Z axis and causing the material 10 to shift.

[0052] Furthermore, please refer to Figures 2 to 3 , the bracket further includes a positioning member (not shown in the figure). The positioning member is detachably connected to the main body 200, and at least part of the positioning member is located in the first accommodation cavity, between the opening and the second baffle 202, and is used to abut against the pallet 300 to limit the movement of the pallet 300 towards the opening direction.

[0053] In this embodiment, since the first rolling assembly 210 can rotate at a fixed point and the frictional force of the rolling friction between the pallet 300 and the first rolling assembly 210 is small, after the bracket is accidentally touched and shaken, the pallet 300 may move towards the opening direction (Y direction shown in the figure), and then cause the pallet 300 to slip out. In this embodiment, a positioning member is provided, and the positioning member can clamp the pallet 300 between the second baffle 202 and itself, thereby preventing the pallet 300 from moving towards the opening direction.

[0054] When it is necessary to make the pallet 300 move towards the opening direction and then enter a processing device such as a degreasing and sintering furnace 100, the positioning member can be disassembled. It should be understood that the positioning member can be designed as a bolt or a buckle, etc. When the positioning member is a bolt, it can be inserted through the main body 200 from bottom to top, with one end exposed upwards and abutting against the pallet 300. When it is necessary to move the pallet 300, only need to loosen the bolt so that it falls off the main body 200 downward to release the restriction on the pallet 300 and allow the pallet 300 to move towards the opening.

[0055] Further, please refer to Figures 1 to 3 , the bracket further includes at least two directional wheels 500, at least one universal wheel 400 and a stopper. The two directional wheels 500 and the universal wheel 400 are both connected to the bottom surface of the main body 200, and the stopper is connected to the main body 200 for restricting or allowing the universal wheel 400 to roll.

[0056] In this embodiment, the bracket generally needs to move between multiple devices in the degreasing and sintering process, thereby realizing the transfer of the material 10. The combination of the directional wheels 500 and the universal wheels 400 in the embodiment of the present application can enable the bracket to turn and move freely, while avoiding the problem that the bracket is not easy to fix and prone to spontaneous rotation after all the wheels are set as universal wheels 400.

[0057] On the other hand, the stopper can be any structure that can stop the universal wheel 400. For example: the stopper is a bolt passing through the main body 200. When it is necessary to restrict the rolling of the universal wheel 400, only need to rotate the bolt so that one end of it abuts against the universal wheel 400, and the restriction of the universal wheel 400 is realized by means of friction. The stopper can also be a bolt pin, and the fixation of the universal wheel 400 is realized by inserting it into a set socket in the universal wheel 400.

[0058] Correspondingly, please refer to Figures 1 to 3 , the present application provides a degreasing and sintering device, and the degreasing and sintering device includes the bracket in any one of the above embodiments and a degreasing and sintering furnace 100.

[0059] In this embodiment, when the material 10 is placed on the first rolling assembly 210 and is pushed by the user, the first rolling assembly 210 will also roll. Therefore, there is a rolling contact between the material 10 and the first rolling assembly 210, the friction force is small, and the force required is also small, effectively improving the degreasing and sintering efficiency. At the same time, the user can first stack multiple materials 10 on the first rolling assembly 210 of the bracket, and then observe from the surrounding of the bracket whether the materials 10 are stacked neatly as expected, thereby avoiding uneven degreasing and sintering of some materials 10, and further improving the finished product rate of degreasing and sintering.

[0060] The degreasing and sintering furnace 100 can be a structure formed by two furnaces, a degreasing furnace and a sintering furnace, or can be a single furnace, and the specific situation is determined according to the process conditions. When it is necessary to start the degreasing and sintering process, the user can open the closing door 110 (not marked in the figure) of the degreasing and sintering furnace 100 to expose the internal space. After exposing the internal space, the user can abut the bracket against the internal space, and then directly push the material 10 into the internal space under the fixed-point rotation action of the first rolling assembly 210, so as to complete the feeding work at one time.

[0061] It should be understood that the processing steps of the material 10 are injection molding machine processing, degreasing and sintering, and screen printing. The bracket can transport multiple materials 10 at one time, and there is no need to re-stack the materials 10 after transportation. Therefore, it can enable the materials 10 to be quickly transported from the injection molding machine to the degreasing and sintering furnace 100, and then quickly transported from the degreasing and sintering furnace 100 to the screen printing processing workshop. That is, after the injection molding process is completed, the user can stack the injection-molded materials 10 on the bracket one by one, and then transfer the entire bracket to the degreasing and sintering furnace 100. Then, the material 10 is pushed into the degreasing and sintering furnace 100 by means of the first rolling component 210 for degreasing and sintering. After the degreasing and sintering process is completed, the materials 10 can be dragged out all at once and transferred to the bracket, and finally the bracket is pushed into the screen printing workshop for screen printing processing.

[0062] Further, please refer to Figures 2 to Figure 4 , a second accommodation cavity (not marked in the figure) is provided in the degreasing and sintering furnace 100. The second accommodation cavity is used to accommodate the material 10, and a plurality of second rolling components 120 are provided. The second rolling components 120 are used to rotate at a fixed point in at least one direction to at least support the material 10 and allow the material 10 to move along the surface of the first rolling component 210;

[0063] Wherein, the height of the upper surface of the second rolling component 120 is less than or equal to the height of the upper surface of the first rolling component 210.

[0064] In this embodiment, since the height of the upper surface of the second rolling component 120 is less than or equal to the height of the upper surface of the first rolling component 210, when the material 10 or the pallet 300 moves towards the second rolling component 120 under the directional rolling action of the first rolling component 210, the second rolling component 120 can receive the material 10 that moves from the first rolling component 210 to the second accommodation cavity, and can facilitate the user to drive the material 10 to move to a specific position in the second accommodation cavity. In summary, the second rolling component 120 can improve the speed of the material 10 entering the degreasing and sintering furnace 100, thereby improving the degreasing and sintering efficiency.

[0065] Further, please refer to Figure 2 and Figure 4 , the degreasing and sintering device further includes a second support member 130. The second rolling component 120 includes a second rolling shaft 121 and at least two second rollers 122. The second rolling shaft 121 is fixedly connected to the inner wall of the second accommodation cavity and passes through the second rollers 122. The second support member 130 is located between adjacent second rollers 122 and is used to support the second rolling shaft 121; and / or,

[0066] The degreasing and sintering device further includes a first support member 220. The first rolling assembly 210 includes a first rolling shaft 211 and at least two first rollers 212. The first rolling shaft 211 is fixedly connected to the inner wall of the second accommodation cavity and passes through the second roller 122. The first support member 220 is located between adjacent second rollers 122 and is used to support the first rolling shaft 211.

[0067] In this embodiment, the second rollers 122 in the second rolling assembly 120 can support the material 10 or the tray. At the same time, the second rollers 122 can rotate around the second rolling shaft 121, so as to realize rolling contact with the material 10 or the tray, thereby reducing the friction of the material 10 or the tray.

[0068] Since the second rolling assembly 120 is located in the degreasing and sintering furnace 100, the second rolling shaft 121 is prone to deformation under the baking and heating of the degreasing and sintering furnace 100. Especially when the material 10 or the pallet 300 is pressed on the second rollers 122, the second rolling shaft 121 between adjacent second rollers 122 is prone to be pressured and bend towards the middle section of itself. Therefore, the second support member 130 can effectively support this part of the second rolling shaft 121 and prevent the second rolling shaft 121 from bending and causing the material 10 or the tray to deviate from the preset position. Similarly, the first support member 220 can effectively prevent the first rolling shaft 211 from bending.

[0069] Further, please refer to Figure 1 , the degreasing and sintering device further includes a partition plate (not shown in the figure). The partition plate is a hollow structure and is used to separate adjacent materials 10; and / or,

[0070] The degreasing and sintering furnace 100 and the bracket are snap-connected; and / or,

[0071] The degreasing and sintering furnace 100 and the bracket are thread-connected.

[0072] In this embodiment, the partition plate can be used to separate the materials 10, so that the hot air in the degreasing and sintering furnace 100 can evenly bake the surfaces of multiple materials 10 and prevent the materials 10 from being too close to each other and causing uneven baking. The snap connection and the thread connection can prevent the bracket from shifting during the process of pushing the material 10 into the degreasing and sintering furnace 100. It should be understood that the degreasing and sintering furnace 100 can also be provided with a positioning groove 9 (not shown in the figure). The shape of the positioning groove is similar to the shape of the bracket, so as to facilitate the connection of the bracket to the preset position of the degreasing and sintering furnace 100, thereby improving the efficiency of the material 10 entering the degreasing and sintering furnace 100.
