[0001] This utility model relates to the field of liquid spraying equipment technology, specifically a reciprocating mobile liquid spraying device. Background Technology

[0002] In the processing of glass substrates, it is often necessary to spray etching solutions onto the surface of the glass substrate. For example, a spraying device such as a dedicated nozzle can be used to spray the etching solution evenly onto the surface of the glass substrate from the top in a near-mist spray manner. However, existing spraying devices and nozzles are usually directly fixed to the production line, meaning that the spraying device cannot move on its own. This makes it impossible to ensure that the etching solution is evenly distributed across all areas of the glass substrate surface when spraying large glass substrates, thus affecting the etching quality of the glass substrate. Utility Model Content

[0031] like Figures 1 to 7 As shown, a reciprocating mobile liquid spraying device includes a pusher plate 1;

[0032] The spraying unit 11 is used to spray liquid onto a vertically arranged workpiece, and the spraying unit 11 is connected to the push plate 1.

[0033] Drive unit 2, which is connected to push plate 1, is used to drive push plate 1 to reciprocate along a first direction so that push plate 1 drives liquid spraying unit 11 to reciprocate along the first direction, the first direction being parallel to the workpiece;

[0034] Guide unit 3 is connected to push plate 1 and is used to guide push plate 1 to move along the first direction.

[0035] The reciprocating spraying device in this solution is particularly suitable for spraying liquid onto workpieces such as glass substrates, for example, spraying developing solution, etching solution, or coating solution onto the surface of the glass substrate. Of course, in other embodiments, the reciprocating spraying device can also be used to spray liquid onto conventional workpieces. In this solution, the first direction is parallel to the setting direction of the workpiece, that is, the horizontal distance between the spraying unit 11 and the workpiece remains unchanged during the movement, and it can move back and forth and / or up and down relative to the workpiece. For example, from the front of the workpiece, the spraying unit 11, driven by the drive unit 2, can move up and down (from above to below the workpiece), move back and forth (from the left to the right of the workpiece), or even move from any diagonal to the opposite diagonal of the workpiece. However, considering the overall size of the device, since the overall height of the device is large and the space occupied is large when using the up and down movement path, the preferred movement path of the spraying unit 11 driven by the drive unit 2 is to reciprocate back and forth along the first direction.

[0036] Specifically, the drive unit 2 drives the push plate 1 to reciprocate horizontally, thereby driving the spraying unit 11 to reciprocate horizontally as well. Compared to traditional fixed spraying devices, the spraying unit 11 in this reciprocating spraying device can spray the liquid onto different positions on the workpiece surface during its movement, covering the entire surface of the workpiece. This avoids situations where some areas receive less liquid, thus better ensuring the uniformity of the liquid on the glass substrate. While the drive unit 2 drives the push plate 1 and the spraying unit 11 to reciprocate along the first direction, this solution also includes a guide unit 3 to provide horizontal guidance, further limiting the reciprocating movement of the spraying unit 11 along the first direction and ensuring the accuracy of the spraying process.

[0037] Furthermore, such as Figures 2 to 6 As shown, the driving unit 2 includes a driving component 21, a connecting plate 22, and a connecting rod 23. The driving component 21 is connected to the connecting plate 22, and the two ends of the connecting rod 23 are respectively connected to the connecting plate 22 and the push plate 1. The driving component 21 is used to drive the connecting plate 22 to move along the first direction, so as to drive the connecting rod 23 and the push plate 1 to reciprocate along the first direction.

[0038] In this embodiment, the driving force for the push plate 1 to move is provided by the driving component 21. The connecting plate 22 moves back and forth under the drive of the driving component 21, which also moves the push plate 1 back and forth, thereby driving the spraying unit 11 to move back and forth along the workpiece to uniformly spray the liquid onto different positions on the workpiece surface. The driving unit 2 has high transmission efficiency and transmission accuracy.

[0039] The specific structure of the driving component 21 can adopt an existing hydraulic telescopic structure or a lead screw structure, etc. Of course, the driving component 21 can also be set as a motor, with the end of the motor connected to a horizontally arranged rotating arm. The bottom end of the rotating arm is provided with a connecting shaft, and the bottom end of the connecting shaft is movably set in a movable groove on the connecting plate 22. The motor drives the rotating arm to rotate at a low speed. During the rotation, the front-to-back position of the rotating arm and the connecting shaft in the first direction changes continuously. Since the connecting shaft is connected to the connecting plate 22, the connecting plate 22 will move back and forth continuously following the rotation of the connecting shaft. Since the connecting plate 22 has a movable groove for the connecting shaft to move, when the left-to-right position of the connecting shaft changes during the rotation, the connecting shaft will reciprocate in the movable groove, thereby realizing that the connecting shaft only drives the connecting plate 22 to move back and forth, but does not drive it to move left and right.

[0040] Furthermore, it also includes a guide sleeve 24 for guiding the connecting rod 23 to move along the first direction. The guide sleeve 24 is detachably fixed to an external device, and the guide sleeve 24 is sleeved on the outer wall of the connecting rod 23. In this embodiment, in order to further restrict the movement of the connecting rod 23 along the first direction, a guide sleeve 24 is also sleeved in the middle of the connecting rod 23. Since the guide sleeve 24 is fixedly installed on the external device, its position is fixed. Therefore, the middle of the connecting rod 23 is limited by the guide sleeve 24 to prevent it from deviating during movement.

[0041] Furthermore, such as Figure 5 and Figure 7 As shown, the guide unit 3 includes a guide rod 31 and a guide wheel 32. The guide wheel 32 is rotatably mounted on the push plate 1. The guide rod 31 is detachably fixed to an external device and extends along the first direction. The guide wheel 32 is slidably engaged with the guide rod 31.

[0042] To more accurately restrict the movement of the push plate 1 along the first direction, in this embodiment, a guide rod 31 and a guide wheel 32 cooperate to provide guidance. Typically, the guide rod 31 is horizontally fixed on an external device, and two guide wheels 32 are installed on the push plate 1. There is a guide gap between the two guide wheels 32, and the guide rod 31 is inserted into the guide gap. Therefore, when the push plate 1 moves, the cooperation between the two guide wheels 32 and the horizontally arranged guide rod 31 ensures that the push plate 1 always reciprocates along the first direction.

[0043] Furthermore, such as Figure 6 As shown, the driving component 21 is mounted on the base 4 via a connecting block 25. The base 4 is detachably fixed to an external device. At least one adjustment hole 251 is provided on each side of the connecting block 25. A bolt is inserted into the adjustment hole 251, and the end of the bolt is connected to the base 4.

[0044] In this embodiment, in order to improve the fit between the connecting shaft (rotating arm) and the connecting plate 22 and to better insert the connecting shaft into the movable slot 241, the position of the driving component 21 can also be finely adjusted. The connecting block 25 is installed on the base 4 by bolts. The output end of the driving component 21 passes through the connecting block 25 and is connected to the rotating arm. When the position of the connecting shaft needs to be finely adjusted, the bolts are removed and the position of the bolts is moved in the adjustment hole 251 so that the position of the driving component 21 is forward or backward. The forward and backward positions of the rotating arm and the connecting shaft connected to it will also be adjusted.

[0045] Furthermore, such as Figure 3 As shown, it also includes a sensing unit 5 for detecting the moving position of the connecting plate 22. The sensing unit 5 includes a proximity sensor 51 and a sensing plate 52. The proximity sensor 51 is detachably fixed to an external device, and the sensing plate 52 is disposed on the connecting plate 22. The proximity sensor 51 is used to detect the sensing plate 52 on the connecting plate 22. When the sensing plate 52 enters the detection range of the proximity sensor 51, the proximity sensor 51 emits a signal.

[0046] In this embodiment, the movement process of the reciprocating mobile spraying device can also be monitored in real time to ensure it is normal. This is achieved through the cooperation of the proximity sensor 51 and the sensing plate 52. Since the proximity sensor 51 is installed on an external device, its position is fixed. The sensing plate 52 is usually installed on the upper surface of the connecting plate 22. When the connecting plate 22 moves the sensing plate 52 to the detection range of the proximity sensor 51, it can be sensed by the proximity sensor 51. Therefore, the reciprocating mobile spraying device can monitor the number of reciprocations of the connecting plate 22 and its operating status.

[0047] Furthermore, the push plate 1 includes two spaced-apart side plates 12, and multiple reinforcing plates 13 are spaced apart between the two side plates 12 along the height direction of the push plate 1. When the weight and volume of the spraying unit 11 are large, in order to better push the spraying unit 11, the structure of the push plate 1 is reinforced in this embodiment. Specifically, the push plate 1 is composed of two side plates 12, and multiple reinforcing plates 13 are also provided between the two side plates 12. In this way, the strength of the entire push plate 1 is high, and it can drive the spraying unit 11 to move more stably.

[0048] Furthermore, two spraying units 11 are respectively provided on both sides of the workpiece, and two connecting rods 23 are respectively provided at both ends of the connecting plate 22. Each connecting rod 23 is connected to a corresponding push plate 1 at its end, and each push plate 1 is connected to the corresponding spraying unit 11.

[0049] In this way, one driving component 21 can simultaneously drive the movement of two spraying units 11 on both sides of the workpiece, resulting in a simpler overall structure and greater energy efficiency. Specifically, one driving component 21 is connected to a connecting plate 22, which is connected to two connecting rods 23, and the two connecting rods 23 are connected to corresponding push plates 1, thereby enabling the movement of the two spraying units 11.

[0050] Furthermore, each of the push plates 1 is provided with a guide unit 3 at both its upper and lower ends. In this embodiment, in order to achieve a better horizontal guiding effect for the movement of the push plate 1, guide units 3 are provided at both the upper and lower ends of the push plate 1 to guide its movement.

[0051] In a more preferred embodiment, push plates 1 are provided on both sides of the spray unit, and guide units 3 are provided at the upper and lower ends of the push plates 1 on both sides. That is, a spray unit is guided horizontally by four guide units 3. In order to simplify the structure, a drive unit 2 is usually provided only on one side of the spray unit, and the push plate 1 on the other side moves accordingly without a corresponding drive unit 2.

[0052] Furthermore, the spraying unit 11 includes a liquid supply assembly and a vertically arranged mounting plate 111. Multiple nozzles 112 are spaced apart on the mounting plate 111, and each nozzle 112 is connected to the liquid supply assembly via a pipe. The surface of the workpiece is sprayed with liquid from the multiple nozzles 112 to ensure uniform distribution of the liquid.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
