Ground connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal connection between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood through specific circumstances.

As shown in Figure 1, a schematic structural diagram of an automatic centering device for sticky rods, an automatic centering device for sticky rods includes a measuring device, a pre-pressure device, a to-be-pulled device and a lifting and positioning device.

The measuring device is arranged on one side of the stick-sticking table 29 and is used for positioning and adjusting the positions of the material frame 30 and the material seat 31 . Optionally, the measuring device is in a parallel position to the stick-gluing stage 29 to facilitate transferring the material frame 30 to the stick-gluing stage 29 . In the orientation shown in Figure 1, the measuring device can be arranged on the right side of the stick-gluing stage.

The pre-pressing device is connected to one side of the rod-gluing stage 29 and is not on the same side as the measuring device. The pre-pressing device is used to press down the crystal rod 28 . Optionally, pre-pressing devices are connected on both sides of the stick-gluing stage 29 . In the illustrated direction of FIG. 1 , the pre-pressure device is arranged on the left side of the stick-sticking table 29 .

The device to be pulled is arranged on one side of the pre-pressing device and not on the same side as the measuring device. After the pre-pressing of the crystal rod 28 is completed, the material frame 30, the material seat 31 and the crystal rod 28 thereon are moved to the device to be pulled.

The lifting and positioning device is arranged on one side of the to-be-pulled device and is not on the same side as the measuring device. It is used to center the material frame 30, the material seat 31 in the material frame 30, and the crystal rod 28 connected to the material seat 31 by glue.

As shown in Figure 2, specifically, the measuring device includes a support plate 4, a guide rod cylinder 2 provided on one side of the support plate 4, and a first stop cylinder 3 provided on the opposite side of the guide rod cylinder 2. The guide rod cylinder 2 pushes Material frame 30, the first stopping cylinder 3 prevents the material frame 30 from continuing to advance; when adjusting the position, the material seat 31 is placed in the material frame 30, the material frame 30 is placed on the support plate 4, and the guide rod cylinder 2 pushes the material frame 31, Cooperate with the first stop cylinder 3 to fix the position of the material frame 30 to the preset position, preferably, The number of guide rod cylinders 2 is two, and they are spaced on the same side of the support plate 4. They can push the material frame 30 at the same time so that the material frame 30 will not tilt, which facilitates subsequent glue application and placement of the crystal ingot 28.

In some feasible embodiments, the measuring device also includes a displacement sensor 1 arranged on the guide rod cylinder 2. The displacement sensor 1 is used to detect whether the material seat 31 is in a preset position. Preferably, the number of displacement sensors 1 is consistent with the guide rod.

Preferably, the number of pressing down cylinders 8 is 2 and evenly distributed. The pressure exerted on the crystal rod 28 enables the crystal rod 28 to be bonded to the glue more uniformly, thereby avoiding uneven glue coating. The second stop cylinder 7 is symmetrically installed on the inner surface of the two side beams of the first support frame 5 and is used to fix the position of the material frame 30 to prevent the material frame 30 from moving back and forth during pre-pressure, resulting in uneven bonding of the crystal ingot 28 , thus affecting subsequent processes.

When the material frame 30 moves to the bottom of the crossbeam of the first support frame 5 , the second stop cylinder 7 fixes the position of the material frame 30 , and the downward pressure cylinder 8 presses down the crystal ingot 28 in the material frame 30 to pre-press the crystal ingot 28 Bond with the material seat 31.

In some feasible embodiments, the pre-pressure device also includes linear bearings 6 arranged on both sides of the pressing cylinder 8, which cooperate with the pressing cylinder 8 to press down the crystal ingot 28 to achieve a uniform pressing force. Since a crystal rod weighs about 200 kilograms, when pressing down the crystal rod 28, a relatively large pressure is required, and it needs to be applied evenly, so a linear bearing is provided on both sides of each pressing cylinder 8. 6.

The length is the distance between the preloading device and the lifting positioning platform to ensure that the thrust piece The sliding of 11 is in a stable state, preventing the crystal rod 28 from large position deviation.

When the material frame 30 moves to the thrust member 11, the ejection cylinder 10 pushes the thrust member 11 along the guide rail 12 to the lifting positioning device.

In some feasible embodiments, rolling wires are provided on both sides of the stick-gluing stage 29 for moving the material frame 30 on the stick-gluing stage 29. Due to the setting of the push-out mechanism, there is a gap between the stick-gluing stage 29 and the device to be pulled. There is a gap in the line body between them, so a transition line body 32 is provided on the side of the guide rail 12 close to the lifting positioning device.
