Description

Technical Field

[0001] This utility model relates to the field of automated circuit board production equipment, and in particular to a clamping frame positioning mechanism. Background Technology

[0002] In the manufacturing of specialized semiconductor equipment, such as etching machines, and for automated circuit board production, clamp frames are used to fix the circuit boards during the automated production process. These clamp frames then move between various automated production steps. The automatic loading of the circuit board onto the clamp frame is a crucial step. Currently, clamp frames are typically vertically picked up and placed from an automated transport vehicle using a frame-retrieving assembly. A moving frame then fits against the clamp frame, and several pressing mechanisms along the edges of the moving frame press against the clamp frame's edge to fix it in place before the board is loaded. However, existing clamp frame fixing mechanisms only fix the frame's edge; the alignment accuracy between the clamp frame and the moving frame can only be detected by sensors, lacking a correction and guidance mechanism. Furthermore, only the clamp frame's edge is subjected to pressure, failing to ensure a tight fit and fixation of the entire clamp frame to the moving frame, thus affecting the accuracy of the board loading.

The clamping frame is provided with a plurality of gourd holes, including a large hole and a small hole whose centers are located on the same vertical axis and are interconnected. A plurality of telescopic cylinders are provided on the sliding frame. An alignment rod is provided at the movable end of the telescopic cylinder. An alignment pressure joint is coaxially provided at the front end of the alignment rod. The diameter of the alignment pressure joint is larger than the diameter of the alignment rod and the small hole. The sliding frame slides forward to abut against the clamping frame. The telescopic cylinders drive the alignment pressure joint forward to pass through the large hole to align with the clamping frame. The clamping assembly drives the clamping frame to move up and down so that the alignment rod is matched into the small hole. Then, the telescopic cylinders drive the alignment pressure joint to press backward against the periphery of the small hole to fix the clamping frame on the sliding frame.

A fixed frame is provided on one side of the frame-removing assembly. A sliding frame is mounted on the fixed frame, which can slide back and forth relative to the fixed frame to move closer to / away from the frame-removing assembly.

[0021] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "clamping frame positioning mechanism" of this utility model is provided in conjunction with the accompanying drawings.

[0022] See Figures 1-5In this embodiment, the clamping frame positioning mechanism includes a frame-removing component (not shown) capable of vertically picking up and placing the clamping frame 200. The frame-removing component is a prior art mechanism capable of vertically picking up and placing the clamping frame 200. A fixed frame (not shown) is provided on one side of the frame-removing component, and a sliding frame 100 is provided on the fixed frame, which can slide back and forth relative to the fixed frame to approach / move away from the frame-removing component. A plurality of gourd-shaped holes 201 are provided on the clamping frame 200. Each gourd-shaped hole 201 includes a large hole 2011 and a small hole 2012 whose centers are located on the same vertical axis and are interconnected. Preferably, the large hole 2011 is at the bottom and the small hole 2012 is at the top. A plurality of telescopic cylinders 101 are provided on the sliding frame 100, and the movable end of each telescopic cylinder 101 is provided with a... Positioning rod 102, with a positioning crimping connector 103 coaxially arranged at the front end of positioning rod 102. The diameter of positioning crimping connector 103 is larger than the diameter of positioning rod 102 and small hole 2012. During operation, the frame taking assembly clamps the clamping frame 200 and moves it upward to the front of sliding frame 100. Then, sliding frame 100 slides forward to abut against clamping frame 200. Telescopic cylinder 101 drives positioning crimping connector 103 forward through large hole 2011 to align with clamping frame 200. Then, frame taking assembly drives clamping frame 200 to move vertically downward slightly so that positioning rod 102 is matched into small hole 2012. Then, telescopic cylinder 101 drives positioning crimping connector 103 to press backward against the periphery of small hole 2012 to fix clamping frame 200 on sliding frame 100. When the telescopic cylinder 101 drives the alignment crimping connector 103 forward through the large hole 2011 to align with the clamping frame 200, the front-to-back position of the clamping frame 200 can be physically guided. When the frame-removing assembly drives the clamping frame 200 to move vertically downward slightly so that the alignment rod 102 is fitted into the small hole 2012, the left-to-right position of the clamping frame 200 can be physically guided, so that the clamping frame is accurately aligned with the sliding frame 100. Furthermore, when the telescopic cylinder 101 drives the alignment crimping connector 103 to press backward against the periphery of the small hole 2012, it can ensure that the clamping frame 200 is tightly fitted and fixed on the sliding frame 100. This mechanism can simultaneously achieve physical guidance and fixation of the clamping frame 200, and the design structure is simple.

[0023] It should be noted that in other embodiments, the large hole 2011 can be on top and the small hole 2012 on the bottom, and the frame removal assembly can drive the clamping frame 200 to move vertically upward slightly so that the alignment rod 102 is matched into the small hole 2012.

[0024] See further Figure 4 In this embodiment, the alignment crimping connector 103 has a tapered structure with a small front diameter and a large rear diameter, which facilitates the alignment of the clamping plate frame 200 through the tapered inclined surface and prevents damage to the clamping plate frame 200.

[0025] More specifically, in this embodiment, a positioning sensor is provided on the sliding frame 100 to sense whether the clamping frame 200 has moved into place; for example, when the sliding frame 100 moves back and forth, it confirms that the sliding frame 100 has moved to a position close to the clamping frame 200; when the frame-removing assembly drives the clamping frame 200 to move slightly downward, it confirms that the clamping frame 200 has moved to the position of the alignment rod 102 matching the small hole 2012; the sensor confirms whether the relative position of the sliding frame 100 and the clamping frame 200 is in place.

[0026] See further Figure 1 and Figure 2 In this embodiment, a plurality of pressing cylinders 108 are provided around the sliding frame 100. The pressing cylinders 108 are located on the outer periphery of the front end of the sliding frame 100. The movable end of the pressing cylinder 108 is provided with a pressing member 109. The pressing cylinder 108 drives the pressing member 109 to fix the frame 204 of the clamping frame 200, so as to further fix the clamping frame 200 and prevent the clamping frame 200 from shifting when the plate is placed on it.

[0027] See further Figure 2 and Figure 3 In this embodiment, the clamping frame 200 includes a fixed frame strip 202 and a movable frame strip 203, with a clamping interval formed between the fixed frame strip 202 and the movable frame strip 203; a fixed frame 104 and a movable frame 105 are correspondingly provided on the sliding frame 100, and a motor 106 is provided on the fixed frame 104. The movable end of the motor 106 is connected to the movable frame 105 and drives the movable frame 105 to move left and right to approach / move away from the fixed frame 104; both the fixed frame 104 and the movable frame 105 are provided with telescopic cylinders 101, and the telescopic cylinder on the fixed frame 104... 101 drives the alignment crimping connector 103 to pass through the large hole 2011 on the fixed frame strip 202 of the clamping plate frame 200 and then retracts to crimp the small hole 2012. The telescopic cylinder 101 on the moving frame 105 drives the alignment crimping connector 103 to pass through the large hole 2011 on the moving frame strip 203 of the clamping plate frame 200 and then retracts to crimp the small hole 2012. The moving frame 105 drives the moving frame strip 203 to move closer to / away from the fixed frame strip 202 through the alignment rod 102 and the alignment crimping connector 103, thereby adjusting the size of the clamping plate area to facilitate the clamping of circuit boards of different sizes.

[0028] More specifically, such as Figure 2 and Figure 3In this embodiment, the clamping frame 200 includes two adjacent clamping sections on the left and right. Movable frame bars 203 are provided on both the left and right sides of the fixed frame bar 202. Movable frames 105 are provided on both the left and right sides of the fixed frame 104. The movable end of the motor 106 is connected to a lead screw 107. The two movable frames 105 are respectively sleeved on the lead screw 107. The motor 106 drives the two movable frames 105 to move synchronously closer to / away from the fixed frame 104 through the lead screw 107. The two movable frames 105 drive the two movable frame bars 203 to move synchronously closer to / away from the fixed frame bar 202 through the alignment rod 102 and the alignment pressure joint 103. This realizes the automated synchronous adjustment of the double clamping sections and improves the loading efficiency.
