Description

Technical Field

[0001] This utility model relates to the field of material feeding, and in particular to a material feeding and positioning mechanism for a fully automatic screen printing machine. Background Technology

[0002] Feeding refers to the process of automatically or manually sending raw materials, workpieces, or items to be processed into a designated location on the equipment during automated production or processing.

[0003] The automatic screen printing machine's feeding and positioning mechanism is a device used to automatically grab the material to be printed and accurately place it at the printing station.

[0004] The existing fully automatic screen printing machine feeding and positioning mechanism has the following shortcomings: Existing technologies have significant shortcomings in use. Traditional screen printing machines have low automation levels and rely on manual feeding, resulting in slow feeding speed, poor positioning accuracy, and difficulty in improving production efficiency. This increases labor costs and operational error risks, hindering the realization of large-volume, high-precision production. There is an urgent need to improve the feeding method to enhance overall operational efficiency and stability. Utility Model Content

Through the above components, the feeding efficiency is greatly improved and the labor cost is reduced.

[0007] Preferably, a PLC controller is fixedly installed on one side of the front of the fixed plate, and a screen printing table is fixedly installed on the top of the fixed plate. The PLC controller can realize the automated control of the entire material loading and positioning process. The operator only needs to set the parameters through the controller and does not need to manually intervene in the operation of each component, thus simplifying the operation process.

[0008] Preferably, a limiting rod is fixedly connected to the inner wall of the fixed plate, and the outer wall of the limiting rod is slidably connected to the inner wall of the second slider. The limiting rod restricts the movement direction of the second slider, preventing the second slider from deviating or shaking during the sliding process, and indirectly ensuring that the transverse plate always maintains a stable trajectory.

[0009] Preferably, a set of sliding rods is fixedly connected to the outer wall of the transverse plate. The shaft end of the sliding rod is fixedly connected to the outer wall of the clamping plate. When the electric push rod drives the clamping plate to move, the sliding rod can provide guidance for the clamping plate and prevent the clamping plate from tilting or shifting during the clamping process.

[0010] Preferably, a servo motor is fixedly installed on the outer wall of the fixed plate. The output end of the servo motor is fixedly connected to one end of the lead screw. The thread on the outer wall of the lead screw penetrates the inner wall of the first slider. The servo motor has high-precision speed control and position control capabilities, which can accurately drive the lead screw to rotate, thereby driving the first slider and the transverse plate to move.

[0011] Preferably, an encoder is fixedly installed on the inner wall of the fixed plate, and the outer wall of the encoder is fixedly connected to the other end of the lead screw. The encoder can detect the number of rotations and angle of the lead screw in real time and feed the data back to the PLC controller.

[0012] Preferably, the bottom of each support leg is fixedly connected with a rubber pad. The rubber pad has good anti-slip properties, which can increase the friction between the support leg and the ground and prevent the equipment from shifting due to vibration during operation.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the first slider, the second slider and the lead screw work together to drive the transverse plate to move automatically, and combined with the electric push rod to push the clamping plate to hold the substrate, effectively replacing manual operation, significantly improving the feeding speed, reducing labor costs and operating errors.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a fully automatic screen printing machine feeding and positioning mechanism, including a feeding mechanism 1, with support legs 2 fixedly connected to the bottom of the feeding mechanism 1; the feeding mechanism 1 includes a fixed plate 101, with a first slider 107 and a second slider 110 slidably connected to the inner wall of the fixed plate 101 respectively, and a transverse plate 103 fixedly connected to the outer wall of the first slider 107 and the second slider 110, with a set of industrial cameras 112 fixedly installed on the top of the inner wall of the transverse plate 103, and a set of electric push rods 115 fixedly installed on the outer wall of the transverse plate 103, with a set of clamping plates 114 fixedly connected to the shaft end of the electric push rods 115, and a set of anti-slip pads 113 fixedly connected to the outer wall of the clamping plates 114, and a lead screw 106 movably inserted into the inner wall of the fixed plate 101. Through the above components, the feeding efficiency is greatly improved and the labor cost is reduced.

[0020] like Figure 2 As shown, a PLC controller 104 is fixedly installed on one side of the front of the fixed plate 101, and a screen printing table 102 is fixedly installed on the top of the fixed plate 101. The PLC controller 104 can realize the automated control of the entire feeding and positioning process. The operator only needs to set the parameters through the controller and does not need to manually intervene in the operation of each component, which simplifies the operation process.

[0021] like Figure 3 As shown, a limiting rod 109 is fixedly connected to the inner wall of the fixed plate 101. The outer wall of the limiting rod 109 is slidably connected to the inner wall of the second slider 110. The limiting rod 109 restricts the movement direction of the second slider 110, preventing the second slider 110 from deviating or shaking during the sliding process, and indirectly ensuring that the transverse plate 103 always maintains a stable trajectory.

[0022] like Figure 4 As shown, a set of slide rods 111 are fixedly connected to the outer wall of the transverse plate 103. The shaft end of the slide rod 111 is fixedly connected to the outer wall of the clamping plate 114. When the electric push rod 115 drives the clamping plate 114 to move, the slide rod 111 can provide guidance for the clamping plate 114 to prevent the clamping plate 114 from tilting or shifting during the clamping process.

[0023] like Figure 2 As shown, a servo motor 105 is fixedly installed on the outer wall of the fixed plate 101. The output end of the servo motor 105 is fixedly connected to one end of the lead screw 106. The thread on the outer wall of the lead screw 106 passes through the inner wall of the first slider 107. The servo motor 105 has high-precision speed control and position control capabilities, and can accurately drive the lead screw 106 to rotate, thereby driving the first slider 107 and the transverse plate 103 to move.

[0024] like Figure 3 As shown, an encoder 108 is fixedly installed on the inner wall of the fixed plate 101. The outer wall of the encoder 108 is fixedly connected to the other end of the lead screw 106. The encoder 108 can detect the number of rotations and angle of the lead screw 106 in real time and feed the data back to the PLC controller 104. The controller adjusts the running state of the servo motor 105 according to the feedback data to form a closed-loop control.

[0025] like Figure 1 As shown, rubber pads 3 are fixedly connected to the bottom of each support leg 2. The rubber pads 3 have good anti-slip properties, which can increase the friction between the support leg 2 and the ground and prevent the equipment from shifting due to vibration during operation.

[0026] The usage and working principle of this device are as follows: After the printing substrate, such as a plastic plate, is moved onto the screen printing table 102, the industrial camera 112 is first activated. The industrial camera 112 takes real-time pictures of the substrate on the screen printing table 102, capturing its edge, contour, and other positional features. After the pictures are taken, the industrial camera 112 transmits the image data to the PLC controller 104 on the front side of the fixed plate 101. The PLC controller 104 compares and analyzes the actual position of the substrate in the image with the standard position according to the preset substrate standard position parameters to determine whether it is accurate. If the PLC controller 104 determines that the substrate position is qualified, it immediately sends a command to a set of electric push rods 115 to control the retraction of their shaft ends, driving the clamping plate 114 connected to them to move outward to release the substrate. During this process, the slide rod 111 slides synchronously along its own axis, clamping the plate. The movement of 114 provides stable guidance to prevent tilting or deviation. Before the substrate moves to the screen printing table 102, the servo motor 105 drives the lead screw 106 connected to its output end to rotate, which drives the first slider 107 to slide along the inner wall of the fixed plate 101 through thread transmission. At the same time, the limiting rod 109 constrains the movement direction of the second slider 110, so that the second slider 110 and the first slider 107 synchronously drive the transverse plate 103 and the substrate to move towards the screen printing table 102. The encoder 108 detects the number of rotations and angles in real time and feeds the data back to the PLC controller 104 to form a closed-loop control, ensuring the positional accuracy of the transverse plate 103 and the industrial camera 112. With the cooperation of all components, the automatic feeding of the substrate is realized, which significantly improves the feeding efficiency and positioning accuracy, reduces manual intervention, and ensures the stability and continuity of the production process.

[0027] The PLC controller 104, servo motor 105, encoder 108, industrial camera 112, and electric actuator 115 used in this application are all common equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. As for their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
