Description

Technical Field

[0001] The present application belongs to the technical field of rain detection, and specifically relates to a rain system and a production line. Background Art

[0002] A shower room is a through-type room used to shower workpieces (such as the cab of a vehicle) to test their sealing properties. The spray mechanism in the existing shower room can only spray the workpieces with a fixed output water pressure. If workpieces of different sizes are to be tested for showering, the water pressure acting on different workpieces will be different due to the different distances between the workpieces and the spray mechanism, which may not meet the test requirements. In other words, the existing shower rooms have the disadvantages of poor versatility and adaptability, resulting in the need to configure dedicated shower rooms for different types of workpieces, which increases construction costs.

[0041] The following will describe the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present application, and are not used to limit the present application.

[0042] Refer to Figures 1 to 3 , a first exemplary embodiment of the present application provides a rain shower system, including:

[0043] A spraying system 1, including a first base frame 11, two side spraying mechanisms 12 (usually provided with a side spraying rack 121 and a plurality of side spray nozzles 122 installed on the side spraying rack 121, and the spraying liquid can flow through the pipelines formed in the side spraying rack 121 to each side spray nozzle 122), and a first transverse movement mechanism. The first base frame 11 is provided with a first longitudinal workpiece passage. The two side spraying mechanisms 12 are respectively connected to the first base frame 11 in a transversely movable manner and are respectively located on the transverse two sides of the first longitudinal workpiece passage. The first transverse movement mechanism is used to adjust the transverse spacing between the two side spraying mechanisms 12; and

[0044] An identification device, used to identify the workpiece information of the workpiece to enter the first longitudinal workpiece passage. The first transverse movement mechanism can adjust the transverse spacing between the two side spraying mechanisms 12 according to the workpiece information.

[0045] It should be noted that the above workpiece information may be workpiece model information. When the identification device identifies the workpiece model information, the rain shower system can determine the transverse dimension of the workpiece according to the workpiece model information. Alternatively, the above workpiece information may also be workpiece width information. When the identification device identifies the workpiece width information, the transverse dimension (i.e., width) of the workpiece can be directly determined.

[0046] In addition, the identification device can adopt different types of devices. For example, the identification device can be an RFID reader. In this case, an RFID chip containing the above workpiece information can be pre-installed on the workpiece. When the workpiece approaches the RFID reader, the RFID reader can automatically read the workpiece information pre-stored in the RFID chip. Another example is that the identification device can be a two-dimensional code reader. In this case, a two-dimensional code label containing the above workpiece information can be pre-attached to the workpiece. When the workpiece approaches the two-dimensional code reader, the two-dimensional code reader can automatically identify and obtain the workpiece information pre-stored in the two-dimensional code label.

[0047] Through the above settings, the rain shower system of the present application can, before the workpiece enters the first longitudinal workpiece channel of the first base frame 11, identify the workpiece information of the workpiece through the identification device, and then the first transverse movement mechanism can correspondingly adjust the transverse distance between the two side spray mechanisms 12 according to the workpiece information, so as to ensure that there is enough transverse distance between the two side spray mechanisms 12 for the workpiece to pass through, and at the same time ensure that the water pressure exerted by the two side spray mechanisms 12 on the workpiece can meet the requirements of the rain shower test. It can be seen that the rain shower system of the present application can perform rain shower tests on workpieces of various models, has strong versatility and adaptability, and effectively saves costs.

[0048] In some embodiments, the rain shower system further includes:

[0049] A re-inspection device for re-inspecting the transverse dimension of the workpiece to be entered into the first longitudinal workpiece channel;

[0050] Wherein, when the workpiece information obtained by the identification device matches the transverse dimension of the workpiece detected by the re-inspection device, the first transverse movement mechanism can correspondingly adjust the transverse distance between the two side spray mechanisms 12 according to the transverse dimension.

[0051] It should be noted that the re-inspection device can adopt different types of devices, such as different types of ranging sensors such as ultrasonic ranging sensors, laser ranging sensors, infrared ranging sensors, or proximity switches, etc.

[0052] Through the settings of this embodiment, after the workpiece information of the workpiece is identified by the identification device, the transverse dimension of the workpiece can also be re-inspected by the re-inspection device. When the workpiece information obtained by the identification device matches the transverse dimension of the workpiece detected by the re-inspection device, the first transverse movement mechanism of the rain shower system can correspondingly adjust the transverse distance between the two side spray mechanisms 12 according to the transverse dimension of the workpiece. Thus, the rain shower system has a detection anti-error function by configuring the identification device and the re-inspection device, and can effectively reduce the risk of collision between the workpiece and the side spray mechanism 12 caused by the incompatibility between the transverse distance of the two side spray mechanisms 12 and the transverse dimension of the workpiece due to detection errors.

[0053] In some embodiments, the first transverse movement mechanism includes a first transverse movement motor 13 and a transmission mechanism 14 (such as a belt transmission mechanism), and the first transverse movement motor 13, the transmission mechanism 14, and the side spraying mechanism 12 are sequentially connected in transmission. When the workpiece information identified by the identification device matches the lateral dimension of the workpiece detected by the re-inspection device, the first transverse movement motor 13 can drive the transmission mechanism 14 to drive at least one side spraying mechanism 12 to move transversely, so as to adjust the lateral spacing between the two side spraying mechanisms 12 to be compatible with the lateral dimension of the workpiece.

[0054] In some embodiments, the first base frame 11 includes a cross beam, and the two side spraying mechanisms 12 are respectively slidably connected to the two ends of the cross beam in the transverse direction. The first transverse movement motor 13 is fixed in the middle of the cross beam and can drive the transmission mechanism 14 to drive at least one side spraying mechanism 12 to move transversely (such as driving the two side spraying mechanisms 12 to move synchronously and in opposite directions).

[0055] It can be seen that in this embodiment, when it is necessary to adjust the lateral spacing between the two side spraying mechanisms 12, only one first transverse movement motor 13 needs to be configured, which can save the number of first transverse movement motors 13, simplify the first transverse movement mechanism, and save costs.

[0056] In some embodiments, the spraying system 1 further includes:

[0057] A transverse movement positioning device 15, which communicates with the first transverse movement mechanism and can send a first stop transverse movement signal when the first transverse movement mechanism adjusts the lateral spacing between the two side spraying mechanisms 12 to match the lateral dimension, so as to stop the operation of the first transverse movement mechanism. For example, when the first transverse movement mechanism is provided with the aforementioned first transverse movement motor 13, the first transverse movement motor 13 can stop running when receiving the first stop transverse movement signal. In addition, different types of devices such as proximity switches, photoelectric detection switches, and coding scales can be used for the transverse movement positioning device 15, and the specific selection of the transverse movement positioning device 15 in this application is not limited.

[0058] In some embodiments, referring to Figures 1 to 3 , the rain shower system includes a plurality of spraying stations arranged in sequence along the longitudinal direction, and a corresponding spraying system 1 is provided in each spraying station, and the plurality of spraying systems 1 are set to be able to work independently of each other.

[0059] After the workpiece is subjected to a rain shower test by the spraying system 1 in the first spraying station, the workpiece can be continuously moved to the second spraying station, and the workpiece is subjected to a corresponding rain shower test by the spraying system 1 in the second spraying station. And so on, until the workpiece is subjected to a rain shower test by the spraying system 1 in the last spraying station, and then the workpiece is moved to the subsequent station to perform other processes.

[0060] In some embodiments, when the workpiece moves longitudinally in the first longitudinal workpiece channel, the lateral spacing between the two side spraying mechanisms 12 is maintained at a preset maximum spacing. For example, when the rain shower system is provided with the aforementioned multiple spraying stations, when the workpiece moves from the current spraying station to the next spraying station, it is necessary to first adjust the lateral spacing between the two side spraying mechanisms 12 in the current spraying station and the next spraying station to the preset maximum spacing, and then move the workpiece. Through the setting of this embodiment, the collision between the workpiece and the side spraying mechanism 12 during the longitudinal movement of the workpiece can be avoided.

[0061] In some embodiments, the spraying system 1 further includes:

[0062] A collision detection device 17 capable of emitting a workpiece stop signal, a second stop lateral movement signal, and an alarm signal when the workpiece collides with the side spraying mechanism 12.

[0063] Through the setting of this embodiment, the device for transferring the workpiece can immediately stop running when receiving the workpiece stop signal, and the workpiece will immediately stop moving. While the first lateral movement mechanism (such as its first lateral movement motor 13) can immediately stop running when receiving the second stop lateral movement signal, and the two side spraying mechanisms 12 corresponding to the first lateral movement mechanism will immediately stop lateral movement, thereby preventing the collision between the workpiece and the side spraying mechanism 12 from further intensifying and minimizing the loss as much as possible. In addition, the alarm signal can promptly remind the workshop personnel of this collision situation, enabling the workshop personnel to make timely responses to execute remedial measures.

[0064] In some embodiments, the spraying system 1 further includes a top spraying mechanism 16. The top spraying mechanism 16 is installed on the top of the first base frame 11 and is used for spraying the front and rear sides and the top of the workpiece. The top spraying mechanism 16 usually has a top spraying frame and a plurality of top spray nozzles installed on the top spraying frame. The spraying liquid can flow through the pipelines formed in the top spraying frame to each top spray nozzle.

[0065] By providing the top spraying mechanism 16 and the two side spraying mechanisms 12 in the spraying system 1, the rain shower test for the front and rear sides, left and right sides, and the top of the workpiece can be realized.

[0066] Furthermore, in order to improve the versatility and adaptability of the spraying system 1 to workpieces of various models, a first lifting mechanism can also be provided in the spraying system 1. The first lifting mechanism can adjust the vertical spacing between the top spraying mechanism 16 and the ground according to the vertical size of the workpiece, so as to ensure that there is enough vertical spacing between the top spraying mechanism 16 and the ground for the workpiece to pass through, and at the same time ensure that the water pressure exerted by the top spraying mechanism 16 on the workpiece can meet the requirements of the rain shower test.

[0067] Generally, the rain shower system may also be equipped with a water pump system 3 and a connection system 4 (usually in the form of pipelines). The water pump system 3 and the connection system 4 are connected to each side spray mechanism 12 (and each top spray mechanism 16), so that the water pump system 3 provides spray liquid for each side spray mechanism 12 (and each top spray mechanism 16). For example, the connection system 4 can be connected to each of the aforementioned side spray racks 121 (and each of the aforementioned top spray racks).

[0068] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 4 , the rain shower system further includes:

[0069] A drying system 2, including a second base frame 21, side blowing mechanisms 22 (there may be multiple, and usually there are side blowers 221, side air ducts 222 connected to the side blowers 221, and multiple side air outlets 223 provided on the side air ducts 222), and a second transverse movement mechanism. The second base frame 21 is provided with a second longitudinal workpiece passage. The second transverse movement mechanism includes a second transverse movement motor 23 and a transverse guide rail 24 provided on the second base frame 21. The side blowing mechanisms 22 are transversely movably connected to the transverse guide rail 24 and are located laterally outside the second longitudinal workpiece passage. The second transverse movement motor 23 can drive the side blowing mechanisms 22 to move transversely along the transverse guide rail 24 according to the transverse dimension of the workpiece to correspondingly adjust the lateral distance between the side blowing mechanisms 22 and the workpiece.

[0070] The above drying system 2 is usually arranged on the downstream side of the last spray station for drying the sprayed workpiece. Therefore, after the workpiece is output from the first longitudinal workpiece passage of the last spray station, it can immediately enter the second longitudinal workpiece passage of the drying system 2, and then the side blowing mechanisms 22 blow air to the sides of the workpiece to dry the moisture attached to the surface of the workpiece.

[0071] By setting the second transverse movement mechanism to adjust the lateral distance between the side blowing mechanisms 22 and the workpiece according to the transverse dimension of the workpiece, it can ensure that the second longitudinal workpiece passage has sufficient lateral distance for the workpiece to pass through, avoiding collision between the workpiece and the side blowing mechanisms 22.

[0072] When it is necessary to adjust the lateral distance between the side blowing mechanisms 22 and the workpiece, the second transverse movement motor 23 operates, thereby driving the side blowing mechanisms 22 to move transversely along the transverse guide rail 24. For example, when the second transverse movement motor 23 operates, it can drive the side blowers 221 to move transversely along the transverse guide rail 24, thereby synchronously driving the side air ducts 222 to move transversely by the side blowers 221, so as to adjust the lateral distance between the side air ducts 222 and the workpiece.

[0073] In some embodiments, the air-drying system 2 further includes a top blowing mechanism 25, which is installed on the top of the second base frame 21 and is used to blow air on the front and rear sides and the top of the workpiece. The top blowing mechanism 25 generally includes a top blower, a top air duct connected to the top blower, and a plurality of top air outlets provided on the top air duct.

[0074] By providing the top blowing mechanism 25 and the side blowing mechanisms 22 (which may be multiple) in the air-drying system 2, the air-drying treatment of the front and rear sides, the left and right sides, and the top of the workpiece can be realized.

[0075] Further, in order to improve the versatility and adaptability of the air-drying system 2 to workpieces of various models, a second lifting mechanism may also be provided in the air-drying system 2. The second lifting mechanism can adjust the vertical distance between the top blowing mechanism 25 and the ground according to the vertical size of the workpiece, so as to ensure that there is enough vertical distance between the top blowing mechanism 25 and the ground for the workpiece to pass through, and to avoid the workpiece from colliding with the top blowing mechanism 25.

[0076] The second exemplary embodiment of the present application also provides a production line, which includes the above-mentioned rain-showering system. The production line of the present application includes, but is not limited to, assembly production lines for construction machinery, commercial vehicles, and passenger vehicles.

[0077] In some embodiments, the production line further includes a conveying line body (such as a skid conveying line body) for conveying workpieces, and the conveying line body is arranged to pass through the longitudinal workpiece channels (such as the first longitudinal workpiece channel and the second longitudinal workpiece channel) in the rain-showering system, so as to realize the transfer of workpieces.

[0078] Of course, other types of equipment, such as AGV cars, RGV cars, etc., can also be used to transfer workpieces in the production line of the present application, and the present application does not limit this.
