AI Technical Summary
The robot arm cannot identify the forward and reverse directions of the tray, resulting in the circuit board not being able to be placed smoothly when the tray is placed in reverse, affecting the normal operation of the equipment.
A vertical stop bar is added to the pallet frame. The distance between the stop bar and the pallet convex bar is designed to correspond to each other, so that the pallet can only be placed in the forward direction. When placed in the reverse direction, it is blocked by the stop bar to prevent reverse placement.
Effectively prevent the pallet from being placed in reverse, ensuring the normal and stable operation of the equipment and improving operation stability.

Description
TECHNICAL FIELD
[0001] The utility model relates to tray technical field, concretely is a tray anti -reversal structure. BACKGROUND
[0002] The integrated circuit processing equipment blanking part uses a special tray to load circuit, and the operator needs to manually add an empty tray before production operation, then the manipulator puts the tray to the material receiving position and waits for the circuit board to be put into the tray, the tray structure is as shown in Figure 1 The two ends are provided with convex strips, and since the tray is automatically grabbed, the manipulator cannot identify the front and back of the tray, when the tray is in the reverse direction, the grabbed tray is put into the material receiving position, which causes the subsequent circuit board to be unable to be smoothly put in, and affects the normal operation of the equipment. SUMMARY
[0003] In order to solve the above technical problems, the utility model provides a tray anti -reversal structure, which can effectively prevent the tray from being put in reversely and ensure the normal and stable operation of the equipment.
[0004] The technical scheme is as follows: a tray anti -reversal structure, comprising a tray frame, characterized in that the tray frame comprises a front U-shaped frame and a rear U-shaped frame, the inner side surfaces of the front U-shaped frame and the rear U-shaped frame are respectively provided with vertical blocking strips, and the distance from the blocking strip to the inner wall of one side of the front U-shaped frame or the rear U-shaped frame corresponds to the distance from the other side of the convex strip on the tray to one side of the tray.
[0005] Further characterized in that the front U-shaped frame and the rear U-shaped frame are both formed by inserting the left frame plate and the right frame plate, the left frame plate or the right frame plate is provided with an insertion slot, and the right frame plate or the left frame plate is provided with an insertion slot and is locked and fixed by a bolt;
[0006] The inner side surfaces of the front U-shaped frame and the rear U-shaped frame are provided with multiple rows of bolt holes;
[0007] The front U-shaped frame and the rear U-shaped frame are respectively provided with wear-resistant pressing plates on both sides through screws.
[0008] The utility model increases the vertical blocking strip on the original frame, since the convex strips at both ends of the tray are not in the middle position, the distances from the two sides of the convex strip to the two sides of the tray are different, and the distance from the blocking strip to the inner wall of one side of the front U-shaped frame or the rear U-shaped frame corresponds to the distance from the other side of the convex strip on the tray to one side of the tray, so that the tray can only be put in forwardly, and the convex strip will be blocked by the blocking strip when put in reversely, so that it cannot be smoothly put into the tray frame, reminding the operator that it is put in reversely, and ensuring the normal and stable operation of the equipment.

[0013] See Figure 2 , Figure 3 , Figure 4 As shown in the figure, a tray anti-reverse structure includes a tray frame, the tray frame includes a front U-shaped frame 1 and a rear U-shaped frame 2, the inner side of the front U-shaped frame 1 and the rear U-shaped frame 2 is respectively provided with a vertical blocking strip 3 through bolt installation, the distance L from the blocking strip 3 to the inner wall of one side of the front U-shaped frame 1 or the rear U-shaped frame 2 corresponds to the distance from the convex strip 5 on the other side of the tray 4 to one side of the tray 4, generally there is a small gap, to avoid the tray from being stuck, at this time, when the tray 4 is put in in the positive direction, the blocking strip 3 will not affect the convex strip 5, and the tray can be smoothly put in; when the tray 4 is reversed, the position of the convex strip 5 coincides with the blocking strip 3, at this time, the tray 4 cannot be smoothly put in.
[0014] In order to adapt to different width of the tray, the front U-shaped frame 1 and the rear U-shaped frame 2 are designed into adjustable structure, which can be widened horizontally according to needs.
[0015] Specifically, the front U-shaped frame 1 and the rear U-shaped frame 2 are both inserted by a left frame plate 6 and a right frame plate 7, the left frame plate 6 or the right frame plate 7 is provided with an insertion slot, the right frame plate 7 or the left frame plate 6 is provided with an insertion strip inserted into the insertion slot and locked and fixed through a bolt 8, in the embodiment, the left frame plate 6 is provided with an insertion slot, a through hole is formed on the upper surface, the right frame plate 7 is provided with an insertion strip, a plurality of through holes are formed on the upper surface, when adjustment is needed, the bolt 8 is unscrewed, the right frame 7 is moved to adjust, and the bolt 8 is screwed after adjustment to complete fixation
[0016] The inner side of the front U-shaped frame 1 and the rear U-shaped frame 2 is provided with a plurality of bolt holes, the position of the blocking strip 3 can be adjusted according to needs, in actual use, the height of the front U-shaped frame 1 and the rear U-shaped frame 2 is inconsistent, the height of the rear U-shaped frame 2 is high, and therefore the height of the two blocking strips 3 is also different.
[0017] The two sides of the front U-shaped frame 1 and the rear U-shaped frame 2 are respectively provided with an anti-wear pressing plate 10 through a screw 9, in actual use, the anti-wear pressing plate 10 is slightly inwardly folded, the two sides of the tray are in contact with the anti-wear pressing plate 10, the anti-wear pressing plate 10 no longer abuts against the front U-shaped frame 1 and the rear U-shaped frame 2, and frictional contact with the tray frame is reduced.
[0018] The application discloses a reverse-preventing blocking strip, which prevents reverse loading of a tray by blocking the tray, avoids reverse loading completely, and improves the stability of equipment operation.
