[0034] like Figure 1-Figure 8 As shown, this embodiment provides a coating material conveying device, which includes a body 1, a first material conveying mechanism 2 and a second material conveying mechanism 3. The body 1 includes a first chamber 11 and a second chamber 12, the first material conveying mechanism 2 includes a first material conveying driver 21 and a third chamber 22, the second material conveying mechanism 3 includes a limiting portion 31 and a second material conveying driver 32, the first material conveying driver 21 can move the material 100 out of the third chamber 22 along the first direction, so that the material 100 is limited to the limiting portion 31 in the first chamber 11, the second material conveying driver 32 can drive the limiting portion 31 to move along the second direction to the second chamber 12, and can drive the limiting portion 31 to retreat to the recovery position in the first chamber 11, the material 100 on the limiting portion 31 in the recovery position can be separated from the limiting portion 31, and the second direction is set at an angle with the first direction.

[0035] In this embodiment, the machine body 1 includes a first chamber 11 and a second chamber 12, so that the material 100 can enter the first chamber 11 in advance to wait for processing, and the material 100 is subjected to thermal evaporation and other treatments through the second chamber 12 to achieve film coating. By dividing the machine body 1 into the first chamber 11 and the second chamber 12, it is convenient for the material 100 to achieve vacuum operation in the second chamber 12. The first material transport mechanism 2 includes a first material transport driver 21 and a third chamber 22, and the third chamber 22 is used to accommodate the material 100 to improve the feeding efficiency of the material 100. The second material transport mechanism 3 includes a limiting portion 31 and a second material transport driver 32. The first material transport driver 21 can move the material 100 out of the third chamber 22 along the first direction, so that the material 100 is limited to the limiting portion 31 in the first chamber 11, without manual operation, and with higher efficiency. When the material 100 moves from the third chamber 22 to the first chamber 11, the limiting portion 31 will limit the material 100 to prevent the material 100 from moving and affecting the coating operation. The second material transport driver 32 can drive the limiting portion 31 to move along the second direction to the second chamber 12, and then drive the material 100 to move to the second chamber 12 for heating and coating. After the material 100 operation is completed, the second material transport driver 32 can drive the limiting portion 31 to return to the recovery position in the first chamber 11, and the material 100 on the limiting portion 31 at the recovery position can be separated from the limiting portion 31 and recycled, and it can also facilitate the next material 100 to continue to realize the above-mentioned loading and unloading operations. The second direction is set at an angle with the first direction to facilitate the conveying and limiting of the material 100. Through the above arrangement, the coating material conveying device of this embodiment can efficiently and conveniently realize the loading and unloading of the material 100, and the coating effect is better.

[0036] It should be noted that in this embodiment, both the first direction and the second direction are horizontal, and the first direction is perpendicular to the second direction, so as to facilitate the reasonable layout of various components and the loading and unloading of the material 100. In other embodiments, the first direction and the second direction can be adjusted according to the actual coating operation, and no excessive restrictions are made here. In addition, it can be understood that the material 100 can also be pre-heated in the first chamber 11.

[0037] Specifically, a gate valve is provided between the first chamber 11 and the second chamber 12, and the second chamber 12 is sealed by the gate valve. A vacuum pump is provided in the second chamber 12, and the second chamber 12 is evacuated to a vacuum state by the vacuum pump to prevent impurities from entering the second chamber 12 and affecting the normal coating operation. The specific working principles of the gate valve and the vacuum pump are clear to those skilled in the art, and will not be described in detail here.

[0038] Specifically, Figure 1-Figure 3As shown, a push rod 211 is provided at the output end of the first material transport driver 21, and an abutting portion abutting against the material 100 is provided at one end of the push rod 211 facing the first chamber 11. The first material transport driver 21 can drive the push rod 211 to move in the first direction, thereby pushing the material 100 from the third chamber 22 to the limiting portion 31 in the first chamber 11. By providing the abutting portion, the material 100 can be more stable during the pushing and moving process. In addition, the abutting portion and the material 100 can be configured to be conformally matched to further improve the stability of the loading.

[0039] More specifically, in this embodiment, the first material transport driver 21 includes a cylinder, which is arranged on the machine body 1, and the output end of the cylinder is connected to the push rod 211, which can drive the push rod 211 to move telescopically in the first direction, and the push rod 211 pushes the material 100, thereby completing the feeding operation of the material 100. In other embodiments, the first material transport driver 21 includes a first motor, a first gear and a first rack, the output shaft of the first motor is connected to the first gear, the first gear is meshed and connected to the first rack, and a rod is provided on the first rack, and the first motor drives the first gear to rotate around its own axis, and drives the first rack to move along its own extension direction, and drives the rod to achieve the pushing and feeding of the material 100. That is, the specific structure of the first material transport driver 21 is not limited, as long as it can achieve the above-mentioned functions.

[0040] Specifically, Figure 1-Figure 3 As shown, a stacking groove 221 and a discharge groove 222 are provided in the third chamber 22. One end of the discharge groove 222 is connected to the outside through the stacking groove 221, and the other end is connected to the first chamber 11. A feed port is opened at one end of the stacking groove 221, so that the operator can put the material 100 into the stacking groove 221 through the feed port. A cover plate is provided on the feed port, and the cover plate is connected to the third chamber 22 by screws or buckles to prevent the material 100 from leaking out of the feed port. In addition, the cover plate is made of transparent material, so that the operator can directly observe the accommodation situation of the material 100 in the third chamber 22. The material 100 is accommodated in the stacking slot 221, and the output end of the first material transport driver 21 is slidably disposed in the third chamber 22. The first material transport driver 21 contacts and generates thrust with the material 100 placed in the stacking slot 221 and closest to the discharge slot 222, so that the material 100 in the stacking slot 221 can be pushed into the first chamber 11 along the extension direction of the discharge slot 222 until the material 100 is pushed onto the limit portion 31 in the first chamber 11, ensuring that the limit portion 31 clamps the material 100 without movement. It can be understood that in this embodiment, the feed port is disposed at the top of the stacking slot 221 to facilitate the delivery of the material 100. In other embodiments, the specific position of the feed port can be adjusted according to the actual operation, and no excessive restrictions are made here.

[0041] More specifically, if Figure 2 As shown, in this embodiment, the extending directions of the stacking groove 221 and the discharging groove 222 are set at an angle, and the stacking groove 221 and the discharging groove 222 are connected to each other in an L shape. The material 100 includes a box body and a film material contained in the box body. There are multiple box bodies. The multiple box bodies are contained in the stacking groove 221 under the action of their own weight or other additional forces and are stacked one by one in a vertical row, so that the first material transport driver 21 can move the material 100 from the third chamber 22 to the first chamber 11 one by one, ensuring the full effect of each material 100 and improving the coating effect and quality. It should be noted that the material 100 can be a pill containing a coating raw material, or a coating raw material pill (i.e., the film material of this embodiment) contained in a copper crucible carrier (i.e., the box body of this embodiment), which can be adjusted according to the actual coating operation, and the specific structure of the material 100 is not limited here.

[0042] More specifically, a plurality of stacking slots 221 may be arranged side by side, and two adjacent stacking slots 221 may be separated by a partition, thereby achieving simultaneous loading and conveying of a plurality of materials 100 , thereby improving the loading efficiency.

[0043] Specifically, Figure 2 As shown, a through hole is provided at one end of the stacking groove 221 facing the first material transport driver 21, and a dynamic seal is adopted between the output end of the first material transport driver 21 and the hole wall of the through hole. Specifically, a seal (such as a rubber ring or a polyurethane O-ring) can be adopted to achieve the sealing effect. The seal is clamped between the output end of the first material transport driver 21 and the hole wall of the through hole to ensure that when the push rod 211 slides in the through hole, the internal environment of the third chamber 22 maintains good sealing with the external environment, and prevents impurities such as gas and dust from entering the third chamber 22 and contaminating the material 100, thereby affecting the quality of the coating operation.

[0044] More specifically, if Figure 2 As shown, the diameter of the discharge chute 222 gradually increases in the direction away from the first chamber 11, which helps the material 100 to smoothly enter the discharge chute 222 from the stacking chute 221 under the action of the push rod 211, and continue to be pushed to the first chamber 11. Moreover, through the change in the diameter of the discharge chute 222, the material 100 can be more stable when entering the first chamber 11, which makes it easier for the push rod 211 to accurately push the material 100 onto the limiting portion 31, thereby achieving limiting.

[0045] More specifically, in this embodiment, the discharge chute 222 is tilted downward in a direction away from the first chamber 11, so that the material 100 in the discharge chute 222 is more stable and will not directly move into the discharge chute 222 under the action of its own weight to affect the normal loading operation.

[0046] Specifically, Figure 1-Figure 6As shown, in this embodiment, the second material transport driver 32 includes a cylinder, and the limiting portion 31 includes a limiting platform, which is arranged on the telescopic output shaft of the cylinder, and the limiting platform is driven by the cylinder to move along the second direction. Figure 5 As shown, in order to make the structure of the device more compact and occupy a smaller space, the coating material conveying device also includes a stroke multiplication mechanism 5, which includes a stroke driver 51, a second gear 52, a second rack 53 and a third rack 54. The output end of the stroke driver 51 is rotatably connected to the second gear 52, and can drive the second gear 52 to move along the second direction. The two opposite sides of the second gear 52 are respectively meshed and connected to the second rack 53 and the third rack 54. The second rack 53 and the third rack 54 extend along the second direction and are staggered along the second direction. The third rack 54 is connected to the limit table through a connecting rod. When the second gear 52 moves along the second direction, the second gear 52 rolls relative to the second rack 53 and the third rack 54, thereby increasing the movable distance of the limit table along the second direction. Among them, the stroke driver 51 can adopt a structure such as an electric cylinder or a cylinder, which is not limited too much here. In addition, in order to ensure that the limit platform can slide stably along the second direction, a slide rail extending along the second direction is provided on the body 1, and the connecting rod is slidably connected to the slide rail to improve the stability and accuracy of the limit platform when moving.

[0047] More specifically, in other embodiments, the second material transport driver 32 includes an electric cylinder, which drives the limit table to move along the second direction, thereby facilitating the processing and recycling of the material 100. That is, the specific structure of the second material transport driver 32 is not limited, as long as the above-mentioned functions can be achieved.

[0048] Specifically, Figure 1-Figure 7 As shown, in this embodiment, the limiting portion 31 is provided with a limiting groove 311 extending through the first direction, ensuring that the material 100 can completely enter the limiting groove 311 and abut against the groove wall of the limiting groove 311, so that the material 100 is stably fixed in the limiting groove 311 to prevent movement or tilting. In other embodiments, the limiting portion 31 includes a clamping claw, and the second material transport driver 32 includes a second motor and a bidirectional threaded rod. The output shaft of the second motor is connected to the bidirectional threaded rod, and can drive the bidirectional threaded rod to rotate around its own axis. Two clamping claws are provided and are respectively screwed on the bidirectional threaded rod. The rotation of the bidirectional threaded rod drives the two clamping claws to move toward or away from each other, thereby achieving the clamping and limiting of the material 100, that is, the specific structure of the limiting portion 31 and the second material transport driver 32 is not limited.

[0049] More specifically, if Figure 1 and Figure 7As shown, two limiting protrusions 3111 arranged opposite to each other are provided at the slot mouth of the limiting slot 311, and the two ends of the material 100 can respectively abut against the bottom of the limiting slot 311 and the limiting protrusions 3111, and the two limiting protrusions 3111 can provide additional support and fixation at both ends of the material 100 to ensure that the material 100 will not be displaced during the operation. Along the first direction, the distance between the two limiting protrusions 3111 first decreases and then increases. When the material 100 is pushed in, the distance between the two limiting protrusions 3111 gradually decreases, providing a gradually increasing fixing force for the material 100; when the material 100 needs to be withdrawn, the distance gradually increases, which is convenient for the smooth recovery of the material 100.

[0050] More specifically, Figure 1 and Figure 7 As shown, in this embodiment, the limiting protrusion 3111 is a baffle to prevent the material 100 from sliding out of the limiting groove 311. In other embodiments, the limiting protrusion 3111 is a stopper, that is, the specific structure of the limiting protrusion 3111 is not limited, as long as the above-mentioned functions can be achieved.

[0051] Specifically, Figure 1-Figure 7 As shown, on the side of the two limiting protrusions 3111 away from the second chamber 12, the limiting groove 311 is provided with an upper concave portion and a lower concave portion corresponding to the outer contour of the material 100 at the placement position of the material 100. When the material 100 is placed between the upper concave portion and the lower concave portion, the lower concave portion is adapted to the lower contour of the material 100, that is, the lower concave portion constitutes a support for the material 100; there is a certain gap between the upper concave portion and the material 100, so that the material 100 can be limited in the limiting groove 311, and can be pushed out from between the upper concave portion and the lower concave portion of the limiting groove 311 by the push rod 211.

[0052] Specifically, Figure 7As shown, in order to enable the material 100 on the limiting portion 31 in the recovery position to be able to detach from the limiting portion 31, in the present embodiment, the first material transport driver 21 can drive the push rod 211 to telescopically move along the first direction, and the push rod 211 pushes the material 100 to the limiting portion 31, thereby completing the loading operation of the material 100. After the material 100 has passed the heating operation of the second chamber 12, the second material transport driver 32 will return the limiting portion 31 and the material 100 thereon to the recovery position (i.e., equivalent to the position where the material 100 is initially limited on the limiting portion 31), and the first pushing driver will drive the push rod 211 to push the material 100 again, thereby pushing the processed material 100 out from the limiting portion 31, thereby realizing the unloading operation of the material 100. In other embodiments, the coating material transport device also includes a third material transport driver, which may adopt a structure such as an electric cylinder or a pneumatic cylinder. The material 100 is pushed out from the limiting portion 31 through the third material transport driver, that is, the specific structure of the third material transport driver is not limited, as long as the above-mentioned functional effects can be achieved.

[0053] It should be noted that the material 100 on the limiting part 31 in the recovery position can be separated from the limiting part 31 by utilizing the mechanism design of the limiting part 31 itself or other mechanism designs outside the limiting part 31, thereby recovering the material 100, which is not further limited here.

[0054] Specifically, Figure 1-Figure 7 As shown, the body 1 also includes a recycling bin 13, which is used to store and recycle materials 100 (such as box bodies) that have completed the coating process or need to be replaced. The recycling bin 13 is tilted and detachably connected to the first chamber 11, which helps the material 100 to slide smoothly under its own gravity or slight external force, and facilitates the collection and subsequent processing of the material 100. At the same time, in this embodiment, the recycling bin 13 is screwed to the first chamber 11, which facilitates the disassembly and maintenance of various components. In other embodiments, the recycling bin 13 can be snap-connected to the first chamber 11 by a buckle to achieve the above function, that is, the above detachable method is not limited.

[0055] Specifically, Figure 1-Figure 8 As shown, the second material transport mechanism 3 also includes a first angle adjustment component 4. The output end of the second material transport driver 32 is connected to the limit portion 31 through the first angle adjustment component 4. The first angle adjustment component 4 can drive the limit portion 31 to rotate around a first direction to adapt to different coating requirements or material 100 processing requirements. During the coating operation, in order to adapt to the size, shape and other requirements of the parts to be coated, the rotation angle of the limit portion 31 is adjusted through the first angle adjustment component 4, thereby adjusting the normal direction of the surface to be coated (i.e., the surface to be evaporated of the film material) of the material 100, so that the film material can better achieve evaporation and ensure the coating effect of the parts to be coated.

[0056] It should be emphasized that in this embodiment, evaporation coating is taken as an example. Since the normal direction of the surface to be evaporated of the film material will affect the coating effect of the part to be coated, the direction of the surface to be evaporated of the film material can be adjusted by adjusting the rotation direction of the material 100, thereby ensuring the coating effect of the part to be coated. In other embodiments, sputtering coating or ion plating can also be used, and the coating method is not limited here.

[0057] Specifically, Figure 4 and Figure 8 As shown, in this embodiment, the first angle adjustment component 4 includes a first connecting member 41 and a second connecting member 42. The limiter 31 is detachably connected to the first connecting member 41 to facilitate the disassembly and maintenance of each component. The output end of the second material transport driver 32 is detachably connected to the second connecting member 42. The first connecting member 41 is provided with an arc-shaped adjustment groove 411, and the second connecting member 42 is provided with an adjustment nut 421. By adjusting the position of the adjustment nut 421 in the adjustment groove 411, the rotation angle of the limiter 31 can be adjusted, that is, the normal direction of the surface to be coated of the material 100 can be adjusted to ensure the coating effect. Among them, the detachable connection of the above-mentioned components can be achieved by bolts or screws, which are not limited too much here.

[0058] More specifically, in another embodiment, the first angle adjustment component 4 includes a third motor, a third gear and a fourth gear. The third motor is disposed at the output end of the second material transport driver 32. The third gear is connected to the output shaft of the third motor and meshedly connected to the fourth gear. The fourth gear is disposed on the limiting portion 31. The third motor drives the third gear to rotate around its own axis and drives the fourth gear to rotate around its own axis, thereby realizing the rotation of the limiting portion 31 around the first direction. In other embodiments, the limiting portion 31 can also be directly driven by a stepper motor or a servo motor to realize rotation. The specific structure of the first angle adjustment component 4 is not limited here, as long as the above-mentioned functions can be realized.

[0059] More specifically, the third chamber 22 is rotatably connected to the first chamber 11. When the limiting portion 31 rotates to adapt to the requirements of the coating operation, the third chamber 22 rotates relative to the first chamber 11, thereby ensuring that the material 100 can accurately enter the limiting groove 311 under the driving action of the first material transport driver 21 to achieve limiting, thereby avoiding interference between the material 100 and the limiting groove 311 and being unable to enter the limiting groove 311.

[0060] Specifically, Figure 1-Figure 3 and Figure 7As shown, the first material transport mechanism 2 also includes a second angle adjustment component 23, and the third chamber 22 is connected to the first chamber 11 through the second angle adjustment component 23. The second angle adjustment component 23 can drive the material 100 in the third chamber 22 to rotate around the first direction so that the material 100 can better realize the loading operation.

[0061] More specifically, if Figure 1-Figure 3 and Figure 7 As shown, in this embodiment, the second angle adjustment component 23 includes two flanges arranged opposite to each other, one of which is connected to the first chamber 11, and the other is connected to the third chamber 22. A plurality of connection holes are arranged at intervals along the circumferential direction on the flanges, and the first chamber 11 and the third chamber 22 can be connected to each other by fasteners passing through the corresponding connection holes on the two flanges. When the operator needs to adjust the rotation angle of the third chamber 22 relative to the first chamber 11 around the first direction, the angle adjustment can be achieved by screwing the fasteners and replacing the corresponding connection holes, thereby adjusting the direction of the material 100 in the third chamber 22 and improving the accuracy of pushing and loading. Among them, the fasteners can be screws or bolts. In other embodiments, the specific structure of the second angle adjustment component 23 can refer to the first angle adjustment component 4, which will not be repeated here.

[0062] This embodiment also provides a coating method, which uses the above-mentioned coating material conveying device, and the material 100 includes a box body and a film material contained in the box body. The coating method includes the following steps:

[0063] Step 1: Place the material 100 in the third chamber 22 .

[0064] In this step, the operator opens the cover plate and puts the material 100 into the stacking slot 221 through the feed port, so that multiple boxes are accommodated in the stacking slot 221 under the action of their own weight and are stacked one by one in a vertical row.

[0065] Step 2: Push the box body in the third chamber 22 onto the limiting portion 31 in the first chamber 11 through the first material transport driver 21 .

[0066] In this step, the first material transport driver 21 can drive the push rod 211 to move along the first direction, and the abutting part of the push rod 211 touches the box body, so that the box body can be more stable during the pushing movement, and then the box body is pushed from the third chamber 22 to the limiting part 31 in the first chamber 11. Two limiting protrusions 3111 arranged opposite to each other are provided at the groove mouth of the limiting groove 311, and the two ends of the box body can respectively abut the bottom of the limiting groove 311 and the limiting protrusion 3111. The two limiting protrusions 3111 can provide additional support and fixation at both ends of the box body to ensure that the box body will not be displaced during operation.

[0067] Step 3: The second material transport driver 32 drives the limiting portion 31 holding the box body to move into the second chamber 12, and the film coating is achieved by heating and evaporating the film material.

[0068] In this step, the first material transport driver 21 drives the push rod 211 to move back in the first direction to avoid interfering with the limiting part 31 moving in the second direction, and then opens the gate valve, so that the second material transport driver 32 drives the limiting part 31 and the box body thereon to move to the second chamber 12 to wait for heating and other treatments. At this time, the gate valve is closed to put the interior of the second chamber 12 in a vacuum state, and then the film material in the box body is heated by the second chamber 12 to realize the coating operation of the parts to be coated.

[0069] It should be noted that a gate valve is provided between the first chamber 11 and the second chamber 12, and both are provided with a vacuum pump. During step 1 and step 2, the gate valve is closed. After completing step 1, the vacuum pumps of the first chamber 11 and the second chamber 12 start to work. After completing step 2 and the vacuum degree in the first chamber 11 meets certain requirements, the gate valve is opened, and the first chamber 11 and the second chamber 12 are connected, that is, the second chamber 12 is always in a vacuum state during the coating process.

[0070] Step 4: After the film material is evaporated, the second material transport driver 32 drives the limiting part 31 to retreat to the recovery position.

[0071] In this step, the gate valve is in an open state, so that the second material transport driver 32 drives the limiting part 31 and the box body thereon to move to the recovery position in the first chamber 11, so that the first material transport driver 21 pushes the processed material 100 out from the limiting part 31, and then closes the gate valve.

[0072] Step 5: The first material transport driver 21 pushes the next box body onto the limiting portion 31 , and pushes the heated box body out from the limiting portion 31 .

[0073] In this embodiment, the material 100 is first placed in the third chamber 22, so that the first material transport driver 21 can push the box body in the third chamber 22 onto the limiting portion 31 in the first chamber 11, thereby improving the loading efficiency and ensuring that the box body is stable and does not move, thereby ensuring the coating effect. The limiting portion 31 holding the box body is driven by the second material transport driver 32 to move to the second chamber 12, and the coating is achieved by heating and evaporating the film material. After the film material is evaporated, the second material transport driver 32 drives the limiting portion 31 to retreat to the recovery position, so that the first material transport driver 21 can push the next box body onto the limiting portion 31 for a new round of coating operation, and push the heated box body out of the limiting portion 31 for recycling operation. Through the above-mentioned settings, the coating method of this embodiment can stably and efficiently realize the loading, processing, unloading and recycling operations of the material 100, and the coating effect is better.
