[0051] Please see Figure 1 This utility model provides a loading and unloading device 10 for loading materials into or unloading materials from a coating equipment or transfer device 20.

[0052] Please combine Figure 2 andFigure 3 The loading and unloading device 10 includes a frame 11, a transfer assembly 12, and a drive assembly 13. The transfer assembly 12 includes a transfer mechanism 121 and a support base 122. The transfer mechanism 121 and the support base 122 are slidably connected to the frame 11 along a preset direction X. The support base 122 supports the transfer mechanism 121. The transfer mechanism 121 is used to carry the carrier plate 30. The preset direction X includes opposite first directions X1 and second directions X2. The transfer mechanism 121 can slide along the first direction X1 to the feeding station and have the support base 122 supported at the first end 12121 of the transfer mechanism 121. It can also slide along the second direction X2 to the initial station and have the support base 122 supported at the second end 12122 of the transfer mechanism 121. The drive assembly 13 is connected to the transfer mechanism 121 and is used to drive the transfer mechanism 121 to slide along the first direction X1 or the second direction X2.

[0053] Specifically, such as Figure 1 As shown, when the transfer mechanism 121 is in the initial position, both the first end 12121 and the second end 12122 of the transfer mechanism 121 are on the frame 11, and the support base 122 can be positioned to support the second end 12122. During the process of the transfer mechanism 121 sliding from the initial position to the feeding position along the first direction X1, the transfer mechanism 121 can first slide relative to the support base 122, causing the second end 12122 to gradually move away from the support base 122 until the structure at the first end 12121 abuts against the support base 122. Then, the transfer mechanism 121 can drive the support base 122 to slide together along the first direction X1 until the transfer mechanism 121 is in the feeding position. Figure 2 As shown, at this time, the support base 122 is supported at the first end 12121 of the transfer mechanism 121, and the second end 12122 of the transfer mechanism 121 extends out of the frame 11 so that the second end 12122 of the transfer mechanism 121 can extend into the internal cavity of the coating equipment or transfer device 20, thereby feeding the coating equipment or transfer device 20, that is, placing the carrier plate 30 on the transfer mechanism 121 into the internal cavity of the coating equipment or transfer device 20, or unloading the coating equipment or transfer device 20, that is, receiving the coating equipment. The carrier plate 30 is located in the internal cavity of the transfer device 20. During the process of the transfer mechanism 121 sliding from the feeding station to the initial station along the second direction X2, the transfer mechanism 121 can first slide relative to the support seat 122, causing the second end 12122 to gradually approach the support seat 122. Until the structure at the second end 12122 abuts against the support seat 122, the transfer mechanism 121 can drive the support seat 122 to slide together along the second direction X2 until the transfer mechanism 121 is in the initial station. Figure 1As shown, at this time, the support base 122 is supported at the second end 12122 of the transfer mechanism 121, and the second end 12122 of the transfer mechanism 121 is retracted onto the frame 11 to remove the carrier plate 30 received from the coating equipment or transfer device 20, or simply reset it for reloading.

[0054] In this embodiment of the invention, by slidably connecting both the transfer mechanism 121 and the support base 122 to the frame 11, the support base 122 supports the transfer mechanism 121. The transfer mechanism 121 can slide along the first direction X1 to the feeding position or along the second direction X2 to the initial working position. The support base 122 is positioned close to the first end 12121 or the second end 12122 of the transfer mechanism 121, so that the second end 12122 extends out of the frame 11 or retracts into the frame 11. When the transfer mechanism 121 is mounted on the frame 11, the support base 122 can support the transfer mechanism 121 at the first end 12121 or the second end 12122. Combined with the sliding connection between the transfer mechanism 121 and the frame 11, the transfer mechanism 121 can obtain better support, stabilize the force on the transfer mechanism 121, improve the transfer mechanism 121's resistance to sagging deformation, thereby improving the load-bearing capacity of the transfer mechanism 121 and improving the stability of the transfer mechanism 121 in reciprocating sliding.

[0055] like Figure 1 and Figure 3 As shown, in some embodiments, the transfer mechanism 121 includes a connecting seat 1211, a carrier arm 1212, and an abutment member 1213. The connecting seat 1211 is slidably connected to the frame 11, the carrier arm 1212 is connected to the connecting seat 1211, the connecting seat 1211 is located at the first end 12121 of the transfer mechanism 121, the abutment member 1213 is connected to the carrier arm 1212, the abutment member 1213 is located at the second end 12122 of the transfer mechanism 121, the carrier arm 1212 is used to carry the carrier plate 30, the support seat 122 supports the carrier arm 1212, the support seat 122 is located between the abutment member 1213 and the connecting seat 1211, and the projection of the support seat 122, the connecting seat 1211, and the abutment member 1213 overlaps in a preset direction X. With the above settings, the linkage between the transfer mechanism 121 and the support base 122 can be realized, so that when the transfer mechanism 121 slides along the first direction X1, it can abut against the support base 122 through the connecting seat 1211, thereby driving the support base 122 to slide synchronously along the first direction X1. When the transfer mechanism 121 slides along the second direction X2, it can abut against the support base 122 through the abutting member 1213, thereby driving the support base 122 to slide synchronously along the second direction X2.

[0056] Specifically, during the sliding of the transfer mechanism 121 along the first direction X1, the connecting seat 1211 can slide relative to the support seat 122 toward the support seat 122. Simultaneously, the connecting seat 1211, through the carrier arm 1212, drives the abutment 1213 to move away from the support seat 122 relative to it. When the connecting seat 1211 abuts against the support seat 122, the connecting seat 1211 drives the support seat 122 to slide synchronously along the first direction X1 to the feeding station. At this point, the connecting seat 1211 and the support seat 122 are jointly supported by the end of the carrier arm 1212 away from the abutment 1213, while the other end of the carrier arm 1212 extends away from the connecting seat 1211. The machine frame 11 is exited; during the sliding process of the transfer mechanism 121 along the second direction X2, the connecting seat 1211 can slide away from the support seat 122 relative to the support seat 122. At the same time, the connecting seat 1211 drives the abutment 1213 to move relative to the support seat 122 towards the support seat 122 through the carrier arm 1212 until the abutment 1213 abuts against the support seat 122. The abutment 1213 drives the support seat 122 to slide synchronously along the second direction X2 to the initial position. At this time, the connecting seat 1211 and the support seat 122 are respectively supported at both ends of the carrier arm 1212, and the other end of the carrier arm 1212 away from the connecting seat 1211 is retracted onto the machine frame 11. During the switching process between the initial station and the feeding station, the support seat 122 always maintains its supporting function on the carrier arm 1212, and can support the carrier arm 1212 at the corresponding position according to the change of position when the transfer mechanism 121 slides, so that the transfer mechanism 121 obtains a good supporting function and stabilizes the force on the transfer mechanism 121.

[0057] like Figure 1 As shown, in some embodiments, there are at least two carrier arms 1212, which are arranged side by side and spaced apart. Each carrier arm 1212 is connected to a connecting seat 1211, and a support seat 122 supports each carrier arm 1212. Each carrier arm 1212 together carries the carrier plate 30, so that the carrier plate 30 can obtain stable support on the carrier arm 1212.

[0058] In some embodiments, the transfer mechanism 121 further includes a connecting arm 1214 that connects each carrier arm 1212 so that each carrier arm 1212 is fixed relative to each other, preventing the carrier arms 1212 from spreading apart and improving the structural stability of the transfer mechanism 121.

[0059] In some embodiments, there are two carrier arms 1212 and one connecting arm 1214, with each end of the connecting arm 1214 connected to one of the two carrier arms 1212. In other embodiments, the number of carrier arms 1212 and the number of connecting arms 1214 can be selected according to actual needs and are not limited to the two or one mentioned above. For example, there are three carrier arms 1212 and two connecting arms 1214, with the three carrier arms 1212 arranged side by side and spaced apart, and the two connecting arms 1214 arranged spaced apart along the length of the carrier arms 1212, with each connecting arm 1214 connecting to the three carrier arms 1212.

[0060] Optionally, the length direction of the carrier arm 1212 is parallel to the preset direction X, and the length direction of the connecting arm 1214 is perpendicular to the length direction of the carrier arm 1212.

[0061] like Figure 3 As shown, in some embodiments, the abutment member 1213 is L-shaped, having a connecting plate 12131 and an abutment plate 12132 perpendicular to each other. The connecting plate 12131 is connected to the other end of the carrier arm 1212 away from the connecting seat 1211, and the abutment plate 12132 extends perpendicularly to a predetermined direction X from one side of the carrier arm 1212, with the projections of the abutment plate 12132 and the support seat 122 overlapping in the predetermined direction X. In other embodiments, the abutment member 1213 may also have other structural shapes, not limited to the L-shaped plate described above. For example, the abutment member 1213 may be straight, with one end inserted into the other end of the carrier arm 1212 away from the connecting seat 1211, and the other end extending perpendicularly to a predetermined direction X from one side of the carrier arm 1212, with the projection of the other end of the abutment member 1213 and the support seat 122 overlapping in the predetermined direction X.

[0062] In some embodiments, the loading and unloading device 10 further includes a first support member 14, which is connected to the frame 11. When the transfer mechanism 121 is in the initial working position, the first support member 14 is located below the transfer mechanism 121 and is opposite to the transfer mechanism 121 in the vertical Y direction. In this way, the first support member 14 can support the transfer mechanism 121 from below. When the linkage between the transfer mechanism 121 and the support seat 122 fails and the support seat 122 cannot be brought back to support it, the transfer mechanism 121 can obtain support from the first support member 14, preventing the transfer mechanism 121 from undergoing large sagging deformation, and to a certain extent ensuring the structural stability of the transfer mechanism 121.

[0063] like Figure 1 and Figure 4As shown, specifically, two first support members 14 are respectively disposed on opposite sides of two carrier arms 1212 along a preset direction X. A force-bearing member 1215 is disposed on each opposite side of the two carrier arms 1212 along the preset direction X. One end of the force-bearing member 1215 is connected to the carrier arm 1212, and the other end of the force-bearing member 1215 extends perpendicularly out of the carrier arm 1212 along the preset direction X. When the transfer mechanism 121 is in its initial position, each first support member 14 is located below its corresponding force-bearing member 1215 and is opposite to its corresponding force-bearing member 1215 in the vertical direction Y. This avoids motion interference between the first support member 14 and the transfer mechanism 121 along the preset direction X. Optionally, each of the two carrier arms 1212 is provided with one first support member 14, and one first support member 14 corresponds to one force-bearing member 1215.

[0064] like Figure 1 As shown, in some embodiments, the loading and unloading device 10 further includes a second support member 15, which is connected to the frame 11. When the transfer mechanism 121 is in the initial position, the second support member 15 is located below the carrier plate 30 on the transfer mechanism 121 and is vertically opposite to the carrier plate 30. In this way, the second support member 15 can support the carrier plate 30 from below. When the transfer mechanism 121 collapses, the carrier plate 30 can obtain support from the second support member 15 to prevent the carrier plate 30 from falling directly onto the frame 11 and causing structural damage.

[0065] Specifically, there are four second support members 15, which are distributed in pairs on opposite sides of the transfer mechanism 121 along a predetermined direction X. This allows the four second support members 15 to form four support points below the carrier plate 30, providing good support for the carrier plate 30. In other embodiments, the number of second support members 15 can be selected according to actual needs, as long as the second support members 15 can support the carrier plate 30 when the transfer mechanism 121 collapses. For example, there are two second support members 15, which are respectively disposed on opposite sides of the transfer mechanism 121 along a predetermined direction X, and each second support member 15 extends along the predetermined direction X to form a support surface of a certain length.

[0066] like Figure 1As shown, in some embodiments, the loading and unloading device 10 further includes a limiting member 16, which is connected to the carrier arm 1212. The limiting member 16 is used to restrict the carrier plate 30 from moving relative to the transfer mechanism 121 in a preset direction X. In this way, the limiting member 16 can make the carrier plate 30 stably supported on the transfer mechanism 121, preventing the carrier plate 30 from sliding relative to the transfer mechanism 121 in the preset direction X during the sliding process. The limiting member 16 also has a positioning function for the carrier plate 30, so that each carrier plate 30 is placed in the same position on the transfer mechanism 121. This is beneficial for positioning the carrier plate 30 when the transfer mechanism 121 extends into the internal cavity of the coating equipment or the transfer device 20, and also facilitates the placement of the carrier plate 30 on the transfer mechanism 121.

[0067] Specifically, there are four limiting members 16, which are distributed in pairs on the two carrier arms 1212. The straight line formed by connecting one limiting member 16 on one carrier arm 1212 with another limiting member 16 on the other carrier arm 1212 is perpendicular to the preset direction X. Similarly, the straight line formed by connecting two limiting members 16 on one carrier arm 1212 with another limiting member 16 on the other carrier arm 1212 is also perpendicular to the preset direction X. This ensures that when the carrier plate 30 is placed on the two carrier arms 1212, the four limiting members 16 are distributed in pairs on opposite sides of the carrier plate 30 along the preset direction X. The four limiting members 16 form four limiting points on opposite sides of the carrier plate 30 along the preset direction X, thus providing a good limiting effect on the carrier plate 30. In other embodiments, the number of limiting members 16 can be selected according to actual needs, as long as the limiting members 16 can restrict the movement of the carrier plate 30 relative to the transfer mechanism 121 along the preset direction X. For example, there are two limiting members 16. The two limiting members 16 are spaced apart along a preset direction X. The two ends of one limiting member 16 are respectively connected to the two carrier arms 1212, and the two ends of the other limiting member 16 are also respectively connected to the two carrier arms 1212, so that each limiting member 16 forms a limiting surface with a certain length to limit the carrier plate 30.

[0068] like Figure 1 As shown, in some embodiments, the loading and unloading device 10 further includes a positioning member 17, which is connected to the frame 11. The positioning member 17 is used to correct the deviation of the carrier plate 30 to adjust the position of the carrier plate 30 on the transfer mechanism 121, so that the carrier plate 30 can enter the internal cavity of the coating equipment or transfer device 20 with the orientation facing the cavity of the coating equipment or transfer device 20.

[0069] Specifically, the frame 11 has at least one positioning element 17 on one side of the carrier plate 30 perpendicular to the preset direction X, or the frame 11 has at least one positioning element 17 on the other side of the carrier plate 30 perpendicular to the preset direction X, or the frame 11 has at least one positioning element 17 on both sides of the carrier plate 30 perpendicular to the preset direction X.

[0070] It is understandable that either the limiting member 16 or the positioning member 17 can be omitted, that is, only the limiting member 16 or the positioning member 17 is provided.

[0071] Please see Figure 5 In some embodiments, the drive assembly 13 includes a first motor 131, a lead screw 132, and a nut seat 133. The first motor 131 is mounted on the frame 11. The lead screw 132 is set along a preset direction X and is rotatably connected to the frame 11. The nut seat 133 is sleeved on the outer periphery of the lead screw 132 and threadedly connected to the lead screw 132. A connecting seat 1211 is connected to the nut seat 133. The output end of the first motor 131 is connected to one end of the lead screw 132. The first motor 131 can drive the lead screw 132 to rotate along its own axis, so that the nut seat 133 can drive the connecting seat 1211 to reciprocate along the axis of the lead screw 132.

[0072] The two ends of the lead screw 132 can be mounted on the frame 11 via bearing seats.

[0073] It is understandable that the output end of the first motor 131 and one end of the lead screw 132 can be connected by a first transmission mechanism to realize the power transmission between the first motor 131 and the lead screw 132. For example, the first transmission mechanism is a combination structure of a pulley and a first transmission belt. Specifically, the first transmission mechanism includes a first pulley, a second pulley, and a first transmission belt. The first pulley is sleeved on the outer periphery of the output end of the first motor 131 and fixed to the output end of the first motor 131. The second pulley is sleeved on the outer periphery of one end of the lead screw 132 and fixed to one end of the lead screw 132. The first transmission belt is wound around the first pulley and the second pulley. When the first motor 131 is started, the output end of the first motor 131 rotates, and drives the lead screw 132 to rotate around its own axis through the first pulley, the second pulley, and the first transmission belt. Of course, the first transmission mechanism can also be a coupling. Specifically, the coupling is connected between the output end of the first motor 131 and one end of the lead screw 132.

[0074] In some embodiments, to ensure that the transfer mechanism 121 always slides along a preset direction X, the loading and unloading device 10 further includes a guide assembly 18, which includes a guide rail 181 and two sliders 182. The guide rail 181 is set along the preset direction X and installed on the frame 11, and the two sliders 182 are slidably connected to the guide rail 181 respectively. One slider 182 is connected to the connecting seat 1211, and the other slider 182 is connected to the support seat 122.

[0075] Specifically, in order to stably support the transfer component 12, there are two sets of guide components 18. The two sets of guide components 18 are arranged side by side and spaced apart. The two ends of the connecting seat 1211 are respectively connected to a slider 182 on the guide rail 181 of the two guide components 18, and the two ends of the support seat 122 are respectively connected to another slider 182 on the guide rail 181 of the two guide components 18.

[0076] like Figure 1 As shown, in some embodiments, the loading and unloading device 10 further includes at least two safety light curtains 19. The at least two safety light curtains 19 are respectively disposed on opposite sides of the transfer component 12 along a preset direction X. Each safety light curtain 19 is connected to the frame 11. The safety light curtain 19 is used to sense whether there is an external object or a human hand passing through the upper or lower side of the safety light curtain 19. If so, the drive component 13 is controlled to stop conveying the carrier plate 30 to prevent external objects from entering the conveying area of ​​the transfer component 12 and causing structural damage, or human hands from entering the conveying area of ​​the transfer component 12 and causing injury, thereby improving the safety of the loading and unloading device 10.

[0077] Optionally, the safety light curtain 19 is parallel to a preset direction X.

[0078] Please see Figure 6 This utility model also provides a transmission device 100, which includes a transfer device 20 and a loading / unloading device 10 as described above. The transfer device 20 includes a housing 21 and a conveying assembly 22. The sidewall of the housing 21 defines a first cavity 211 and at least one second cavity 212, which communicate with the interior of the housing 21. The first cavity 211 allows a second end 12122 to pass through and enter the interior of the housing 21, and each second cavity 212 is used to dock with a corresponding coating device. The conveying assembly 22 is housed inside the housing 21 and is used to transfer a carrier plate 30 between the transfer device 20 and the coating device through the second cavity 212. The loading / unloading device 10 is disposed on the outside of the housing 21, and the transfer mechanism 121 is used to place the carrier plate 30 onto the conveying assembly 22 through the first cavity 211 or to lift the carrier plate 30 off the conveying assembly 22.

[0079] The second cavity 212 is located on one side of the conveying direction of the conveying assembly 22.

[0080] Optionally, the conveying direction of the conveying component 22 is perpendicular to the preset direction X.

[0081] It is worth noting that in traditional loading and unloading devices that use belts or roller sets for transmission, after the carrier plate 30 has completed coating, when it is transferred from the transfer device 20 to the belt or roller set via the conveyor assembly 22, relative friction occurs between the carrier plate 30 and the belt or roller set, causing the coating layer on the carrier plate 30 to peel off and generate dust. This embodiment of the present invention addresses this issue by utilizing… Figures 1 to 6 The loading and unloading device 10 shown is used to lift the carrier plate 30 on the conveying assembly 22. It can reduce or even eliminate the relative friction between the carrier plate 30 and the transfer mechanism 121 during transfer, thereby reducing or even eliminating the occurrence of dust caused by the film layer falling off when the carrier plate 30 is removed from the transfer device 20. In addition, it can also reduce the amount of belts or rollers used in the transmission equipment 100 and reduce the cavity venting rate.

[0082] Please see Figure 7 In some embodiments, the conveying assembly 22 includes a second motor, a drive shaft 221, a plurality of driven shafts 222, a transmission shaft 223, a plurality of rollers 224, a plurality of first helical gears 225, and a plurality of second helical gears 226. The output end of the second motor is connected to the drive shaft 221; the drive shaft 221 and the plurality of driven shafts 222 are arranged side by side and spaced apart, and the axes of the drive shaft 221 and the plurality of driven shafts 222 are parallel to a preset direction X; a roller 224 is respectively fitted onto both ends of the drive shaft 221 and both ends of each driven shaft 222 and fixed to the roller 224; the transmission shaft 223 is disposed on one side of the drive shaft 221 and each driven shaft 222 along the preset direction X; a first helical gear 225 is respectively fitted onto one end of the drive shaft 221 and each driven shaft 222 near the transmission shaft 223 and fixed to the first helical gear 225; a plurality of second helical gears 226 are spaced apart along the axis of the transmission shaft 223. The second helical gear 226 corresponds to and meshes with each of the first helical gears 225. The second motor can drive the drive shaft 221 to rotate around its own axis. The drive shaft 221 drives the transmission shaft 223 to rotate around its own axis through the first helical gear 225 at one end and a second helical gear 226 corresponding to the first helical gear 225. The transmission shaft 223 drives each driven shaft 222 to rotate around its own axis through the remaining second helical gears 226 and the first helical gears 225 corresponding to the remaining second helical gears 226. In this way, the rollers 224 on the drive shaft 221 and each driven shaft 222 rotate synchronously, thereby realizing the conveying of the carrier plate 30 carried on each roller 224.

[0083] The drive shaft 221, transmission shaft 223 and each driven shaft 222 can be mounted on the housing 21 via bearing seats.

[0084] It is understandable that the output end of the second motor and the drive shaft 221 can be connected by a second transmission mechanism to realize the power transmission between the second motor and the drive shaft 221. For example, the second transmission mechanism is a gear set structure. Specifically, the second transmission mechanism includes a first gear and a second gear. The first gear is sleeved on the outer periphery of the output end of the second motor and fixed to the output end of the second motor. The second gear is sleeved on the outer periphery of the drive shaft 221 and fixed to the drive shaft 221. The first gear and the second gear mesh to start the second motor. The output end of the second motor rotates and drives the drive shaft 221 to rotate through the first gear and the second gear. A reducer can be set between the first gear and the second gear to increase the output torque of the second motor. Of course, the second transmission mechanism can also be a combination structure of pulleys and a first transmission belt. The second transmission mechanism includes a third pulley, a fourth pulley, and a second transmission belt. The second pulley is sleeved on the outer periphery of the output end of the second motor and fixed to the output end of the second motor. The fourth pulley is sleeved on the outer periphery of the drive shaft 221 and fixed to the drive shaft 221. The second transmission belt is wound around the third pulley and the fourth pulley.

[0085] like Figure 6 As shown, in some embodiments, the transfer device 20 further includes a support component 23, which is housed inside the housing 21. The support component 23 is used to transfer the transfer mechanism 121 when it extends into the housing 21 through the first cavity 211. In this way, the second end 12122 can still get support from the support component 23 after extending out of the frame 11, avoiding excessive suspension of the second end 12122 due to excessive extension of the frame 11, preventing the second end 12122 from sagging and deforming, further ensuring the structural stability of the transfer mechanism 121, and allowing the transfer mechanism 121 to bear a large weight.

[0086] Please see Figure 8 In some embodiments, the support assembly 23 includes a support plate 231 and a support wheel 232. The support plate 231 is fixed inside the housing 21, and the support wheel 232 is rotatably connected to the support plate 231. The axis of the support wheel 232 is set perpendicular to the preset direction X. After the transfer mechanism 121 extends into the housing 21 through the first cavity 211, the lower surface of the carrier arm 1212 can abut against the circumferential side of the support wheel 232 and be supported by the support wheel 232. During the movement of the carrier arm 1212 relative to the support wheel 232, sliding friction is generated between the carrier arm 1212 and the support wheel 232.

[0087] Specifically, in order to stably support the second end 12122 of the transfer mechanism 121, there are two sets of support components 23. The two sets of support components 23 are arranged side by side and spaced apart, and one set of support components 23 supports one carrier arm 1212.

[0088] likeFigure 6 As shown, in some embodiments, the transfer device 20 further includes a lifting assembly 24, which is housed inside the housing 21. The lifting assembly 24 is used to lift the carrier plate 30 located on the transfer mechanism 121 or the conveying assembly 22 to transfer the carrier plate 30 between the transfer mechanism 121 and the conveying assembly 22, thereby realizing the loading and unloading of the loading and unloading device 10 within the transfer device 20. By providing a lifting assembly 24 for lifting the carrier plate 30 between the transfer mechanism 121 and the conveying assembly 22, after the carrier plate 30 has completed coating, when the carrier plate 30 is transferred to the transfer mechanism 121 by the conveying assembly 22 to be removed from the transfer device 20, the lifting assembly 24 can first lift the carrier plate 30 so that the second end 12122 can extend into the interior of the housing 21 through the first cavity 211 and be located on the lower side of the carrier plate 30. After the lifting assembly 24 descends and resets, the carrier plate 30 can naturally fall onto the second end 12122. In this way, the relative friction between the carrier plate 30 and the transfer mechanism 121 can be eliminated, thereby preventing the carrier plate 30 from shedding its coating and generating dust when it is removed from the transfer device 20.

[0089] Please see Figure 9 In some embodiments, the lifting assembly 24 includes a first cylinder 241 and a support frame 242. The first cylinder 241 is mounted on the housing 21, and the output end of the first cylinder 241 is connected to the support frame 242. The first cylinder 241 is used to drive the support frame 242 to rise or fall.

[0090] When it is necessary to transfer the carrier plate 30 from the conveying assembly 22 to the transfer mechanism 121, the support frame 242 can be driven to rise by the first cylinder 241, so that the support frame 242 lifts the carrier plate 30 to a certain height, and then the second end 12122 extends into the interior of the housing 21 through the first cavity 211, so that the second end 12122 is located on the lower side of the carrier plate 30. During this process, the other ends of the two carrier arms 1212 away from the connecting seat 1211 are offset from the support frame 242 in the preset direction X. Then, the support frame 242 is driven to descend and reset by the first cylinder 241. During this process, the carrier plate 30 slowly falls onto the second end 12122 as the support frame 242 descends.

[0091] When it is necessary to transfer the carrier plate 30 from the transfer mechanism 121 to the conveying assembly 22, the second end 12122 can first be inserted into the interior of the housing 21 through the first cavity 211, and then the support frame 242 can be driven to rise by the first cylinder 241 so that the support frame 242 lifts the carrier plate 30 on the second end 12122. During this process, the support frame 242 and the other ends of the two carrier arms 1212 away from the connecting seat 1211 are offset from each other in the vertical Y direction. Then, the second end 12122 is withdrawn from the interior of the housing 21 through the first cavity 211. Finally, the support frame 242 is driven to descend and reset by the first cylinder 241. During this process, the carrier plate 30 slowly falls onto the conveying assembly 22 as the support frame 242 descends.

[0092] Specifically, the support frame 242 includes a connecting rod 2421, two support columns 2422, and two brackets 2423. The output end of the first cylinder 241 is perpendicular to and connected to the connecting rod 2421. The two support columns 2422 are parallel to the output end of the first cylinder 241 and are respectively connected to both ends of the connecting rod 2421. The two brackets 2423 are perpendicular to and connected to the two support columns 2422, and are parallel to a preset direction X. The first cylinder 241 and the connecting rod 2421 connected to it are located below the driven shaft 222. One support column 2422 and one bracket 2423 connected to it are inserted between two adjacent driven shafts 222, and another support column 2422 and another bracket 2423 connected to it are inserted between two other adjacent driven shafts 222.

[0093] In some embodiments, the lifting assembly 24 further includes a guide structure for guiding the support frame 242 to move up and down in the vertical direction Y.

[0094] Specifically, the guide structure includes a sleeve 2431 and a guide post. One of the sleeve 2431 and the guide post is installed on the support frame 242, and the other of the sleeve 2431 and the guide post is installed on the housing 21. Both the sleeve 2431 and the guide post are arranged along the vertical direction Y. The sleeve 2431 is sleeved on the outside of the guide post. The sleeve 2431 and the guide post cooperate to guide the support frame 242 to rise and fall along the vertical direction Y.

[0095] More specifically, there are four sleeves 2431 and four guide posts. Two sleeves 2431 are connected to one bracket 2423, and the other two sleeves 2431 are connected to another bracket 2423. The four guide posts are installed on the housing 21, and one sleeve 2431 is fitted onto the corresponding guide post.

[0096] like Figure 6As shown, in some embodiments, the transfer device 20 further includes a sensor 25, which is housed inside the housing 21. The sensor 25 is used to locate the stopping position of the carrier plate 30 on the conveying assembly 22, so that the transfer mechanism 121 can be vertically aligned with the carrier plate 30 after extending into the housing 21 through the first cavity 211, thereby ensuring the accuracy of the transfer position of the carrier plate 30 between the conveying assembly 22 and the transfer mechanism 121.

[0097] Specifically, there are four sensors 25, which are arranged in a rectangular shape at the four vertices. When the conveying assembly 22 transmits the carrier plate 30 from the coating equipment through the second cavity 212, when the four sensors 25 sense that the carrier plate 30 has reached the preset stopping position from the four vertices of the carrier plate 30, the conveying assembly 22 is controlled to stop running in order to carry out the subsequent unloading action.

[0098] like Figure 6 As shown, in some embodiments, the transfer device 20 further includes an air distribution plate 26, which is housed inside the housing 21 and located below the carrier plate 30 on the conveying assembly 22. By providing the air distribution plate 26, when a vacuum or air gap is created inside the housing 21, the air distribution plate 26 can disperse the airflow, allowing the airflow to be evenly distributed around the carrier plate 30, preventing the airflow from impacting the workpiece on the carrier plate 30 and reducing the impact of the airflow on the workpiece on the carrier plate 30.

[0099] like Figure 6 As shown, in some embodiments, the transfer device 20 further includes a valve assembly 27, with a valve assembly 27 respectively provided at the first cavity 211 and each of the second cavities 212, and the valve assembly 27 is used to open or close the corresponding cavity.

[0100] Please see Figure 10 and Figure 11 Specifically, taking the valve assembly 27 located at the first cavity 211 as an example, the valve assembly 27 includes a second cylinder 271, a connecting rod 272, a rotating shaft 273, a rocker arm 274, and a valve plate 275. The output end of the second cylinder 271 is rotatably connected to one end of the connecting rod 272, and the other end of the connecting rod 272 is connected to the rotating shaft 273. The rotating shaft 273 is located on one side of the first cavity 211 and is rotatably connected to the housing 21. One end of the rocker arm 274 is connected to the rotating shaft 273, and the other end of the rocker arm 274 is connected to the valve plate 275. When the output end of the second cylinder 271 extends or retracts, it can drive the valve plate 275 to rotate around the rotating shaft 273 through the connecting rod 272, the rotating shaft 273, and the rocker arm 274, so that the valve plate 275 seals the first cavity 211 or exposes the first cavity 211.

[0101] The rotating shaft 273 can be rotatably connected to the housing 21 via a bearing seat.
