[0029] This embodiment provides a liquid receiving device, as Figures 1-4 shown, which includes a driving unit 100, a connecting seat 200, and a liquid receiving tray 300 slidably connected to the connecting seat 200 in a first direction. A rack 310 extending in the first direction with an extension length of L is fixedly connected to the liquid receiving tray 300; the driving unit 100 includes a driving assembly provided on the connecting seat 200, a first gear 110 and a second gear 120 pivotally connected to the connecting seat 200. Both the first gear 110 and the second gear 120 are engaged with the rack 310 and the distance between them in the first direction is S, where 0.6L ≤ S < L; the driving end of the driving assembly is connected to the first gear 110 and the second gear 120 for driving the first gear 110 and the second gear 120 to rotate.

[0030] This embodiment further provides a processing device, which includes a processing device, a robot, and the above-mentioned liquid receiving device. The connecting seat 200 of the liquid receiving device is connected to the operating end of the robot.

[0031] In the liquid receiving device provided in this embodiment, the liquid receiving tray 300 and the connecting seat 200 are slidably and snap-connected in the first direction through a sliding connection mechanism, thereby limiting the relative position of the liquid receiving tray 300 relative to the connecting seat 200 in the first direction, and correspondingly ensuring the meshing fit between the rack 310 and the first gear 110 and the second gear 120; the driving assembly can drive the first gear 110 and the second gear 120 to rotate counterclockwise or clockwise to drive the rack 310 to move toward both sides in its length direction; the length L of the rack 310 is greater than the distance S between the first gear 110 and the second gear 120. Then, during the transmission of the rack 310 in the first direction, it can be engaged with the first gear 110 and the second gear 120 simultaneously within a certain range.

[0032] For Figure 4Illustrations will be given based on the perspective. In the figure, the left - right direction is the first direction. Along the left - right direction, the gear on the left side is the second gear 120, and the gear on the right side is the first gear 110. The left - right distance between the first gear 110 and the second gear 120 is S. As shown in the area of the solid - line part in the figure, with the rack 310 meshing with the first gear 110 and the second gear 120 in the middle as the initial position, at the initial position, the rack 310 meshes with both the first gear 110 and the second gear 120, and the length that the rack 310 extends to the left beyond the second gear 120 is k, and the length that the rack 310 extends to the right beyond the first gear 110 is k. When in use, the driving unit 100 can drive the first gear 110 and the second gear 120 to rotate counter - clockwise, thereby driving the rack 310 to move to the left. When the rack 310 moves to the left by a distance k, the right end of the rack 310 disengages from the first gear 110, while still remaining meshed with the second gear 120. The driving unit 100 continues to drive the second gear 120 to rotate counter - clockwise, thereby driving the rack 310 to continue moving to the left. As shown in the area of the left - hand side dotted - line part in the figure, when the rack 310 continues to move to the left by a distance S, the right end of the rack 310 reaches the second gear 120. At this time, the rack 310 moves to the maximum stroke to the left, and the distance it moves to the left relative to the initial position is d = L - k = S + k.

[0033] Similarly, as shown in the area of the right - hand side dotted - line part in the figure, the driving unit 100 can drive the rack 310 to move to the right until the left end of the rack 310 reaches the first gear 110. The rack 310 moves to the maximum stroke to the right. At this time, the distance that the rack 310 moves to the right relative to the initial position is d = L - k = S + k. Since 0.6L ≤ S < L, then 0.8S < 0.8L ≤ d ≤ L.

[0034] Then, the liquid - receiving device provided in this embodiment is applied to a processing device. First, according to the relative position between the robot and the processing device during the hand - over operation, the driving assembly can be adaptively adjusted to drive the first gear 110 and the second gear 120 to rotate in different directions, so that the rack 310 drives the liquid - receiving tray 300 to extend left - ward or right - ward towards the processing device, thereby reducing the restrictions on the usage orientation of the robot and the processing device and improving its adaptability. Second, compared with the prior art where the belt transmission mechanism 130 drives the liquid - receiving tray 300 to extend to the left and right sides, and the maximum stroke of its extension to both sides is only 0.5S, which is half of the distance between the two pulleys. In this application, with the meshing cooperation of the first gear 110, the second gear 120 and the rack 310, the maximum stroke of the liquid - receiving tray 300 extending to the left and right sides driven by the rack 310 is greater than 0.8S. The structure is simple, and it can effectively increase the extension stroke of the liquid - receiving tray 300 to the left and right sides, thereby ensuring the liquid - receiving range of the liquid - receiving tray 300 to both sides, improving the liquid - receiving range of the liquid - receiving device and its adaptability to the processing device, and reducing the adverse effects caused by the dripping liquid droplets during the cooperation operation on the robot and the like.

[0035] Of course, in actual use, the initial position of the rack 310 can be any position in its moving stroke along the first direction, and is not limited to the above-mentioned central position.

[0036] Specifically, in this embodiment, along the first direction, the rack 310 is centrally arranged in the liquid receiving tray 300. The length of the liquid receiving tray 300 along the first direction is A, and 0.8A ≤ L ≤ A. The first direction is the length direction of both the rack 310 and the liquid receiving tray 300. Then, the midpoint position in the length direction of the rack 310 coincides with the midpoint position in the length direction of the liquid receiving tray 300. Among them, L ≤ A can ensure that both sides of the rack 310 in the first direction do not protrude from the liquid receiving tray 300, so as to improve the integrity of the liquid receiving device; L ≥ 0.8A can ensure the adaptability of the length of the rack 310 to the length of the liquid receiving tray 300 and ensure the effective liquid receiving range of the liquid receiving tray 300.

[0037] In this embodiment, the liquid receiving device further includes a control component, and the driving component is communicatively connected to the control component; a first position sensor communicatively connected to the control component is provided between the connecting seat 200 and the liquid receiving tray 300. Along the first direction, when the rack 310 reaches the central position between the first gear 110 and the second gear 120, the first position sensor is triggered. Specifically, as Figure 1 shown, a first detection member 240 can be provided on the connecting seat 200, and a first recognition member 320 matching the first detection member 240 is provided on the liquid receiving tray 300. During the process of the liquid receiving tray 300 moving relative to the connecting seat 200 along the first direction, when the rack 310 moves to the central position between the first gear 110 and the second gear 120, the first recognition member 320 reaches the recognition range of the first detection member 240. The first detection member 240 recognizes the first recognition member 320 and feeds back the central position in place signal to the control component, and the control component correspondingly controls the driving component to stop driving the rotation of the first gear 110 and the second gear 120, so as to accurately stop the rack 310 at the central initial position and complete the central reset of the liquid receiving tray 300.

[0038] Similarly, a second position sensor communicatively connected to the control component is provided between the connecting seat 200 and the liquid receiving tray 300. When the corresponding end of the rack 310 and the second gear 120 reaches the first gear 110, the second position sensor is triggered. When the robot is located on the left side of the processing device, the control component controls the drive unit 100 to drive the first gear 110 and the second gear 120 to rotate clockwise, so as to drive the rack 310 to drive the liquid receiving tray 300 to move rightward toward the processing device. When the left end of the rack 310 reaches the first gear 110, the second position sensor is triggered and feeds back a right-in-place signal to the control component, and the control component correspondingly controls the drive component to stop driving the rotation of the first gear 110 and the second gear 120, so as to accurately make the rack 310 and the liquid receiving tray 300 reach the maximum rightward extension stroke, and reduce the occurrence of the situation where the rack 310 disengages from the first gear 110. Specifically, as Figure 2 shown, a second detection member 250 can be provided on the connecting seat 200, and a second identification member 330 can be provided on the liquid receiving tray 300. When the liquid receiving tray 300 moves rightward relative to the connecting seat 200 to the maximum stroke position, the second detection member 250 identifies the second identification member 330 and feeds back the detected identification signal to the control component.

[0039] Similarly, a third position sensor communicatively connected to the control component is provided between the connecting seat 200 and the liquid receiving tray 300. When the corresponding end of the rack 310 and the first gear 110 reaches the second gear 120, the third position sensor is triggered. When the robot is located on the right side of the processing device, the control component controls the drive unit 100 to drive the first gear 110 and the second gear 120 to rotate counterclockwise, so as to drive the rack 310 to drive the liquid receiving tray 300 to move leftward toward the processing device. When the right end of the rack 310 reaches the second gear 120, the third position sensor is triggered and feeds back a left-in-place signal to the control component, and the control component correspondingly controls the drive component to stop driving the rotation of the first gear 110 and the second gear 120, so as to accurately make the rack 310 and the liquid receiving tray 300 reach the maximum leftward extension stroke, and reduce the occurrence of the situation where the rack 310 disengages from the second gear 120. Specifically, as Figure 2 shown, a third detection member 260 can be provided on the connecting seat 200, and a third identification member 340 can be provided on the liquid receiving tray 300. When the liquid receiving tray 300 moves leftward relative to the connecting seat 200 to the maximum stroke position, the third detection member 260 identifies the third identification member 340 and feeds back the detected identification signal to the control component.

[0040] Specifically, in this embodiment, as Figure 1 and Figure 2As shown in the figure, the driving assembly includes a belt transmission mechanism 130 and a driving mechanism 140 provided on the connecting seat 200. The belt transmission mechanism 130 includes a first pulley 131 coaxially connected to the first gear 110, a second pulley 132 coaxially connected to the second gear 120, and a synchronous belt 133 sleeved on both of them. The driving end of the driving mechanism 140 is connected to the first pulley 131 for driving the first pulley 131 to rotate. Both the first gear 110 and the first pulley 131 are fixedly sleeved on the first pivot shaft 150, both the second gear 120 and the second pulley 132 are fixedly sleeved on the second pivot shaft 160. The first pivot shaft 150 and the second pivot shaft 160 are both pivotally connected to the connecting seat 200, and they are arranged in parallel and spaced apart by a distance S along the first direction. Among them, the driving end of the driving mechanism 140 is fixedly connected to the first pivot shaft 150 for driving the first pivot shaft 150 to rotate.

[0041] During use, the driving mechanism 140 drives the first pivot shaft 150 to drive the first pulley 131 and the first gear 110 to rotate synchronously, thereby driving the synchronous belt 133 to rotate. The synchronous belt 133 further drives the second pulley 132, the second pivot shaft 160, and the second gear 120 to rotate synchronously. The first gear 110 and the second gear 120 correspondingly drive the rack 310 to move along the first direction, realizing the rotational drive of the driving unit 100 for the first gear 110 and the second gear 120 and further the linear motion drive of the rack 310. Among them, during the use process, when the rack 310 meshes with both the first gear 110 and the second gear 120, meshes only with the first gear 110, and meshes only with the second gear 120, the belt transmission mechanism 130 always drives the first gear 110 and the second gear 120 to rotate synchronously. When the rack 310 disengages from the first gear 110 (or the second gear 120), the second gear 120 (or the first gear 110) and the first gear 110 (or the second gear 120) always maintain synchronous rotation, thereby ensuring the meshing and matching orientation between the teeth of the second gear 120 (or the first gear 110) and the meshing teeth of the rack 310, so that when the rack 310 moves to the second gear 120 (or the first gear 110), it can smoothly mesh with the second gear 120 (or the first gear 110), correspondingly improving the smooth meshing of the reciprocating motion of the rack 310 with the first gear 110 and the second gear 120, and ensuring the stable drive of the driving unit 100 for the rack 310 and the liquid receiving tray 300.

[0042] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, the connecting base 200 includes a first base body 210. The first base body 210 includes a first supporting portion 211 and a first side connecting portion 212 provided on the first side of the first supporting portion 211. The bottom of the liquid receiving tray 300 and the top of the first supporting portion 211 are slidably clamped along a first direction through a sliding mechanism, and a receiving space 400 is formed at an interval between the liquid receiving tray 300 and the first side connecting portion 212; the rack 310 is located on the side of the liquid receiving tray 300 facing the first side connecting portion 212. A first pivot shaft 150 and a second pivot shaft 160 are pivotally connected to the side of the first side connecting portion 212 facing the liquid receiving tray 300. The first pulley 131 and the first gear 110 are both fixedly sleeved on the first pivot shaft 150, and the second pulley 132 and the second gear 120 are both fixedly sleeved on the second pivot shaft 160; the driving end of the driving mechanism 140 is connected to the first pivot shaft 150. The first supporting portion 211 and the first side connecting portion 212 are in an angular shape. Among them, the first supporting portion 211 upwardly supports and is slidably limited along the first direction to the liquid receiving tray 300 through the sliding mechanism, so as to ensure the position stability of the connection between the liquid receiving tray 300 and the first supporting portion 211; the liquid receiving tray 300 and the first side connecting portion 212 are respectively located on both sides of the width direction of the first supporting portion 211, and a receiving space 400 is formed among the three. The rack 310, the first gear 110, the second gear 120, the first pulley 131 and the second pulley 132 are all accommodated in the receiving space 400. On the basis of realizing the connection and transmission with each other, the first base body 210 and the liquid receiving tray 300 can play a role of shielding and protecting the above-mentioned components on the outside, which can not only improve the overall neatness of the liquid receiving device, but also reduce the collision damage caused by external factors to the above-mentioned components during use, thereby improving the practicability of the liquid receiving device.

[0043] Specifically, as Figure 1 shown, the first side connecting portion 212 includes two side connecting arms 212a that are located at both ends of the first supporting portion 211 along the first direction and extend upward, and a connecting plate 212b connected between the two side connecting arms 212a. The first pivot shaft 150 and the second pivot shaft 160 are both pivotally connected to the connecting plate 212b; the top ends of the two side connecting arms 212a are fixedly connected with a top connecting arm 212c, and the top connecting arm 212c is used for connecting to the end of the robot.

[0044] Preferably, in this embodiment, as Figure 1As shown, the rack 310 is located above the first gear 110 and the second gear 120. The first pulley 131 is located between the first gear 110 and the first side connection portion 212. The drive mechanism 140 is connected to the side of the first side connection portion 212 facing away from the accommodation space 400. On the one hand, the meshing teeth of the rack 310 are located at its bottom. The rack 310 can cover and protect the meshing teeth, the first gear 110 and the second gear 120 from above, so as to ensure the stable meshing cooperation between the meshing teeth and the first gear 110 and the second gear 120, and correspondingly ensure the stable drive of the drive unit 100 for the rack 310. On the other hand, along the width direction of the liquid receiving tray 300, the first gear 110 and the second gear 120 are close to the rack 310, and the first pulley 131 and the second pulley 132 are close to the drive mechanism 140. Thus, on the basis of ensuring the meshing cooperation between the first gear 110, the second gear 120 and the rack 310, and the transmission connection between the first pulley 131, the second pulley 132 and the drive mechanism 140, the layout compactness of each component is effectively improved, thereby reducing the space occupied by the accommodation space 400, correspondingly reducing the volume of the liquid receiving device, and improving its use flexibility.

[0045] Specifically, the drive mechanism 140 can be located on the side of the first side connection portion 212 facing away from the accommodation space 400, and the drive end of the drive mechanism 140 is connected to the end of the first pivot shaft 150 that extends out of the first side connection portion 212.

[0046] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the drive mechanism 140 includes a drive motor 141 provided on the first side connection portion 212, a third pulley 142 fixedly sleeved on the first pivot shaft 150, and a fourth pulley 143 pivotally connected to the first side connection portion 212. A conveyor belt 144 is sleeved on the third pulley 142 and the fourth pulley 143. The drive end of the drive motor 141 is connected to the fourth pulley 143 for driving the fourth pulley 143 to rotate. The position of the fourth pulley 143 can be arranged according to the space outside the first side connection portion 212. Specifically, the drive motor 141 is installed outside the fourth pulley 143.
