Description

Technical Field

[0001] The utility model relates to the technical field of exposure devices, in particular to a multi-table exposure device. Background Art

[0002] When the exposure device exposes the workpiece to be exposed, on the one hand, in order to improve the automation efficiency of the product assembly line production, on the other hand, to prevent the operator from being affected by the high temperature and ultraviolet radiation generated during the exposure process, the workbench of the existing exposure device often has an exposure position and a loading and unloading position. The workpiece to be exposed moves back and forth between the loading and unloading position and the exposure position under the drive of a crawler or a linear motor.

[0003] To improve production efficiency, existing exposure systems feature multiple worktables. Operators sequentially place workpieces onto these platforms at the loading and unloading locations. Driven by a crawler belt or linear motor, the workpieces are moved from the loading and unloading locations to the exposure location for exposure. After exposure is complete, the crawler belt or linear motor moves the workpiece from the exposure location to the loading and unloading locations, where the operator removes it.

[0004] Because multiple tables operate simultaneously and the exposure process is continuous, when the operator places the workpiece to be exposed on or removes it from one table at the loading and unloading position, the workpiece to be exposed on other tables may be in the plate feeding stroke (i.e., moving from the loading and unloading position to the exposure position), the exposure process (i.e., the workpiece to be exposed is being exposed at the exposure position), or the plate retraction stroke (i.e., the exposed workpiece moves to the loading and unloading position after exposure is completed). When other tables are in the plate retraction stroke, if the operator reaches into the loading and unloading position to perform the operation, the two tables are in the process of approaching each other, which is very easy to pinch the operator's hand, posing a threat to the operator's personal safety. Utility Model Content

[0005] One purpose of the utility model is to solve the problem of the operator's hands being easily pinched when the operator is performing loading and unloading operations on one table while other tables are in the plate retracting stroke during the operation of the existing multi-table exposure device.

[0006] In particular, an embodiment of the present application provides a multi-stage exposure apparatus, comprising:

[0007] A workbench, comprising a loading and unloading position for loading and unloading a workpiece to be exposed and an exposure position for exposing the workpiece to be exposed, wherein the loading and unloading position and the exposure position are arranged relative to each other along a first horizontal direction;

[0008] A plurality of tables are sequentially arranged on the workbench along a second horizontal direction, wherein the second horizontal direction is perpendicular to the first horizontal direction, and the tables are used to place the workpiece to be exposed;

[0009] A plurality of driving mechanisms, each of the driving mechanisms corresponding to each of the tables and used to drive the tables to move between the upper and lower material positions and the exposure position;

[0010] An exposure component, used for exposing the workpiece to be exposed;

[0011] a moving assembly, disposed at the exposure position and connected to the exposure assembly, the moving assembly being movable along the first horizontal direction, and the exposure assembly being movable along the second horizontal direction on the moving assembly; and

[0012] A light curtain detection component is arranged at the upper and lower material levels and is used to monitor whether there are any obstructions at the upper and lower material levels. The light curtain detection component is communicatively connected with the driving mechanism and the motion component.

[0013] Furthermore, the light curtain detection component includes:

[0014] A fixed frame, mounted on the upper and lower material positions;

[0015] an optical transmitter, mounted on one side of the fixing frame, for transmitting optical signals; and

[0016] The optical receiver is mounted on a side of the fixing frame opposite to the optical transmitter and is used to receive the optical signal.

[0017] Furthermore, all the tables share one light curtain detection component.

[0018] Furthermore, all the tables share one moving component and the exposure component on the moving component.

[0019] Furthermore, there are two tables among the multiple tables, and when one table is in the exposure position, the other table is in the loading and unloading position.

[0020] Furthermore, the multi-stage exposure device further includes a visual component for identifying the workpiece to be exposed, and the multiple stages share one visual component.

[0021] The beneficial effects of the utility model are:

[0022] 1. By setting up a light curtain detection component, it is possible to detect whether there are any obstructions at the upper and lower material levels, and then control the movement of the console to ensure the safety of the operator.

[0023] 2. All tables share one light curtain detection component. The light curtain detection component is set up above all tables, and one light curtain detection component detects the loading and unloading positions of all tables to avoid physical partitions between tables, leaving enough space for operators to load and unload, making it convenient for operators to perform loading and unloading operations.

[0029] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0031] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] like Figure 1As shown, the multi-table exposure device 100 of the present invention includes a workbench 1, multiple tables 5, multiple driving mechanisms, an exposure component 3, a motion component 2 and a light curtain detection component 6.

[0033] The workbench 1 includes a loading and unloading position for loading and unloading a workpiece to be exposed and an exposure position for exposing the workpiece to be exposed. The loading and unloading position and the exposure position are arranged along a first horizontal direction (see Figure 1 The plurality of tables 5 are arranged relative to each other along the second horizontal direction (see Figure 1 The second horizontal direction is perpendicular to the first horizontal direction, and the table 5 is used to place the workpiece to be exposed. Each of the multiple driving mechanisms corresponds to each table 5 and is used to drive the table 5 to move between the upper and lower material positions and the exposure position. The exposure component 3 is used to expose the workpiece to be exposed. The motion component 2 is set at the exposure position and connected to the exposure component 3. The motion component 2 can move along the first horizontal direction, and the exposure component 3 moves along the second horizontal direction on the motion component 2. The light curtain detection component 6 is set at the upper and lower material positions to monitor whether there are any obstructions at the upper and lower material positions. The light curtain detection component 6 is communicatively connected to the driving mechanism and the motion component 2.

[0034] The operator places the workpiece to be exposed sequentially from the upper and lower material positions onto multiple tables 5. Driven by the drive mechanism, the workpiece is moved from the upper and lower material positions to the exposure position. The motion component 2 drives the exposure component 3 to move and expose the workpiece. After exposure is completed, the drive mechanism drives the workpiece to be exposed and moves it to the upper and lower material positions, where it is removed by the operator. When the operator performs loading and unloading operations at the upper and lower material positions, their hand passes through and is recognized by the light curtain detection component 6. Because the light curtain detection component 6 is in communication with the drive component and the motion component 2, it can control the progress of the relevant drive mechanism according to the progress of the drive mechanism, preventing the table 5 in the plate retraction process from posing a threat to the operator's personal safety.

[0035] In one embodiment, the light curtain detection assembly 6 includes a fixing frame, a light emitter and a light receiver. The fixing frame is mounted on the upper and lower material positions. The light emitter is mounted on one side of the fixing frame for emitting light signals. The light receiver is mounted on the side of the fixing frame opposite to the light emitter for receiving light signals. The light emitted by the light emitter is horizontally directed toward the light receiver and is received and identified by the light receiver. When the operator's hand extends into the upper and lower material positions, the light emitted by the light emitter is partially or completely blocked. When the light receiver does not receive all the light, it means that an obstruction extends into the upper and lower material positions. Through the above arrangement, on the one hand, the installation of the light receiver and the light emitter is facilitated, and at the same time, while realizing the detection of the obstruction, it can avoid that the setting of the light curtain detection assembly 6 interferes with the operator's loading and unloading operations.

[0036] In one embodiment, all the tables 5 share one light curtain detection assembly 6. Figure 1 As shown, a light curtain detection assembly 6 is installed above all the tables 5. A single light curtain detection assembly 6 detects the loading and unloading positions of all tables 5, thereby avoiding physical barriers between tables 5 and leaving sufficient space for operators to perform loading and unloading operations, making loading and unloading operations more convenient for operators. In other embodiments, when there are a large number of tables 5 and the width of each table 5 is large, multiple light curtain detection assemblies 6 can also be used according to actual conditions.

[0037] In one embodiment, all the tables 5 share one motion assembly 2 and the exposure assembly 3 on the motion assembly 2. This avoids conflicts in motion states between the motion assemblies 2 when multiple motion assemblies 2 operate simultaneously, thereby affecting the exposure process.

[0038] When the number of workpieces to be exposed is small, the number of the multiple tables 5 is 2. Furthermore, when one table 5 is in the exposure position, the other table 5 is in the loading and unloading position, and the two tables 5 operate alternately.

[0039] The multi-stage exposure device 100 of the present invention further includes a visual component 4 for identifying the workpiece to be exposed. The multiple stages 5 share one visual component 4. The visual component 4 identifies the position of the workpiece to be exposed and controls the exposure component 3 to perform exposure based on the position information of the workpiece to be exposed, thereby achieving more accurate exposure.

[0040] The present invention further provides a control method for the multi-stage exposure device 100, comprising:

[0041] Step S100: When one of the tables 5 moves to the upper or lower material position and the light curtain detection component 6 detects an obstruction, the movement of the drive mechanism of the other table 5 is controlled according to the progress of the drive mechanism;

[0042] Step S200: When the light curtain detection component 6 detects no obstruction, a no-obstruction signal is generated, and all driving mechanisms are controlled to move according to a preset program.

[0043] When one of the tables 5 is in the loading and unloading position, the light curtain detection component 6 detects an obstruction, indicating that the operator is performing loading and unloading operations. The movement of other driving mechanisms is controlled according to the different progress conditions of the driving mechanisms of other tables 5 to avoid threats to the personal safety of the operator caused by the operation on other tables 5.

[0044] Furthermore, if Figure 2 and Figure 3 As shown, after step S200, the method further includes:

[0045] Step S300: When the table 5 leaves the loading and unloading position, the light curtain detection assembly 6 is turned off. When the table 5 leaves the loading and unloading position, the operator no longer performs loading and unloading operations and does not need to detect obstructions. The light curtain detection assembly 6 is turned off to avoid wasting energy.

[0046] like Figure 4 As shown, further, in one embodiment, step S100 includes:

[0047] Step S110: When one of the workpieces to be exposed is located at the loading and unloading positions, determining whether the other workpieces to be exposed are in the retracting stroke;

[0048] Step S111: When other workpieces to be exposed are in the retracting stroke, it is determined whether the light curtain detection component 6 detects an obstruction;

[0049] Step S112: When the light curtain detection assembly 6 detects an obstruction, it generates an obstruction signal and stops all drive mechanisms. If the light curtain detection assembly detects no obstruction, the process proceeds to step S200. When a workpiece to be exposed is in the loading or unloading position and the light curtain detection assembly 6 detects an obstruction, it indicates that the operator is currently loading or unloading. Meanwhile, if other workpieces to be exposed are in the retraction range, the operator's hands could be easily pinched. At this point, all drive mechanisms are stopped to maximize operator safety.

[0050] like Figure 4 As shown, further, in one embodiment, step S100 includes:

[0051] Step S120: When one of the workpieces to be exposed is located at the loading and unloading positions, determining whether the other workpieces to be exposed are in the plate feeding stroke;

[0052] Step S121: when there is a workpiece to be exposed in the plate feeding stroke, determining whether the light curtain detection component 6 detects an obstruction;

[0053] Step S122: When the light curtain detection assembly 6 detects an obstruction, it generates an obstruction signal and controls the workpiece to be exposed in the plate feed path to continue moving according to a preset program, while the other workpieces to be exposed stop moving. If the light curtain detection assembly does not detect an obstruction, the process proceeds to Step S200.

[0054] When a workpiece to be exposed is at the loading / unloading position and the light curtain detection assembly 6 detects an obstruction, it indicates that the operator is currently loading or unloading the workpiece. For workpieces currently in the plate feed path, the table 5 is positioned away from the loading / unloading position and the operator, allowing continuous plate feeding without threatening the operator's safety. Furthermore, since workpieces in the plate feed path continue to move, operator safety is ensured while ensuring production efficiency.

[0055] like Figure 4 As shown, in one embodiment, step S100 includes:

[0056] Step S130: When one of the workpieces to be exposed is located at the loading and unloading positions, determining whether the other workpieces to be exposed are at the exposure positions;

[0057] Step S131: When there is a workpiece to be exposed at the exposure position, determine whether the light curtain detection component 6 detects an obstruction;

[0058] Step S132: When the light curtain detection assembly 6 detects an obstruction, it generates an obstruction signal and controls the workpiece in the exposure position to continue moving according to the preset program or to stop the workpiece in the exposure position. If the light curtain detection assembly does not detect an obstruction, the process proceeds to step S200.

[0059] When a workpiece to be exposed is at the loading / unloading position and the light curtain detection assembly 6 detects an obstruction, it indicates that the operator is currently loading or unloading the workpiece. For workpieces currently in the exposure position, the table 5 is positioned away from the loading / unloading position and the operator, and continuous board feeding does not pose a threat to the operator's safety. Furthermore, continuous movement of the workpiece in the exposure position ensures production efficiency while ensuring the operator's safety.

[0060] Furthermore, before step S100, the method further includes:

[0061] Step S10: the table 5 moves to the exposure position to expose the workpiece;

[0062] Step S20: After the exposure is completed, the control surface 5 moves upward to the unloading position.

[0063] like Figure 2 As shown, further, in one embodiment, step S10 includes:

[0064] Step S101: When the table 5 moves to the exposure position, the table 5 stops moving;

[0065] Step S102: controlling the motion component 2 to drive the exposure component 3 to move in the first horizontal direction while controlling the exposure component 3 to move along the second horizontal direction on the motion component 2;

[0066] Step S103: controlling the exposure assembly 3 to expose the workpiece.

[0067] When the volume of the workpiece to be exposed is large, it is difficult for the driving mechanism to drive the workpiece to be exposed. It is easier to control the exposure process by using the above-mentioned moving motion component 2 for exposure.

[0068] like Figure 3 As shown, further, in another embodiment, step S10 includes:

[0069] Step S104: when the table 5 moves to the exposure position, the movement of the moving component 2 in the first horizontal direction stops;

[0070] Step S105: controlling the console 5 to move along the first horizontal direction while controlling the exposure assembly 3 to move along the second horizontal direction on the motion assembly 2;

[0071] Step S106: controlling the exposure assembly 3 to expose the workpiece.

[0072] When the workpiece to be exposed is small in size and is convenient to move, the exposure can be performed using the movable table 5 according to the situation.

[0073] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
