Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cell production equipment, in particular to a carrier plate transmission connection device and vacuum equipment. Background Art

[0002] At present, there are generally two forms of lateral positioning and guiding methods for the carrier transmission system in the vacuum chamber of a horizontal vacuum equipment: one is to add a lateral guide wheel, which is used to press against the side of the carrier to prevent the carrier from excessive lateral deflection during the forward movement; the other is to set a rim on the outer side of the transmission wheel, which is used to press against the side of the carrier to prevent the carrier from excessive lateral deflection during the forward movement.

[0003] However, the method of adding lateral guide wheels not only increases costs and increases maintenance workload, but also makes it easy to hit the carrier during the forward movement, and the guide wheels are easily damaged; when a transmission wheel is used to set the rim guide, when one side of the carrier climbs onto the rim due to excessive speed or other reasons, the carrier is in a laterally inclined state. When the lateral displacement of the carrier is too large, the other side of the carrier has no limit position, and there is a risk of the carrier tilting and falling off the transmission wheel.

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Combine the following Figure 1-Figure 4 A carrier plate transmission connection device and a vacuum device provided in an embodiment of the utility model are described.

[0031] Reference Figure 1 and Figure 2 The present embodiment provides a carrier transmission connection device, which includes a carrier 1, a connection portion 2 and a transmission wheel 3.

[0032] The connection part 2 is disposed on both sides of the carrier plate 1 , and the connection part 2 includes a first cross beam 21 . The free end of the first cross beam 21 extends inward to form a first flange 211 .

[0033] The transmission wheel 3 includes a limiting rim 31 and a bearing portion. The limiting rim 31 is arranged at the first end of the transmission wheel 3. The bearing portion is in rolling contact with the bottom surface of the first beam 21 for supporting the first beam 21. A positioning ring groove 32 is arranged between the limiting rim 31 and the bearing portion, and the positioning ring groove 32 is adapted to the first flange 211.

[0034] During operation, the carrier plate 1 is placed on the transmission wheel 3, and the rotation of the bearing part is used to drive the carrier plate 1 to run in the vacuum chamber 6. By providing a limiting wheel rim 31 at the first end of the transmission wheel 3, the first crossbeam 21 is prevented from sliding out of the transmission wheel 3 from the first end of the transmission wheel 3 along the axial direction. The carrier plate 1 can be limited on both sides thereof, thereby preventing the carrier plate 1 from lateral displacement during operation. By providing a positioning ring groove 32 on the transmission wheel 3, so that it is adapted to the first flange 211 of the first crossbeam 21 of the carrier plate 1, since the first flange 211 is embedded in the positioning ring groove 32, the carrier plate 1 can be prevented from lateral displacement during transmission. In this way, through the guiding and limiting effects of the limiting wheel rim 31 and the positioning ring groove 32, it is ensured that the carrier plate 1 will not tilt or detach from the transmission wheel 3, and the transmission is smooth, thereby improving the reliability of the transmission of the carrier plate 1.

[0035] The height of the first flange 211 is smaller than the depth of the positioning ring groove 32 , so that when the two are matched, the first flange 211 can be prevented from contacting the bottom of the positioning ring groove 32 , ensuring that the bearing portion is always in contact with the bottom surface of the first beam 21 .

[0036] Optionally, the first flange 211 is configured to be in an arc shape or a rectangle, and the cross-sectional shape of the positioning ring groove 32 is in a V-shape, an arc shape or a rectangle.

[0037] Preferably, the first flange 211 is arc-shaped, and the positioning ring groove 32 is an arc-shaped groove. Such a configuration can reduce the friction between the first flange 211 and the positioning ring groove 32 during the transmission of the carrier 1, which is conducive to the smooth transmission of the carrier 1. When the carrier 1 is laterally offset, the first flange 211 can contact both sides of the positioning ring groove 32, and the inner side of the positioning ring groove 32 provides reverse resistance to the first flange 211, thereby playing a role in correcting the deviation of the carrier 1.

[0038] In this embodiment, the connecting portion 2 includes a second beam 22, which is relatively arranged below the first beam 21. The distance between the first beam 21 and the second beam 22 is greater than the diameter of the bearing portion. With this arrangement, the second beam 22 can play a dust collecting role below the bearing portion, and is used to collect most of the dust generated by the transmission friction between the transmission wheel 3 and the first beam 21, and take it out of the vacuum chamber 6 for regular cleaning to avoid contaminating the vacuum chamber 6.

[0039] Furthermore, the free end of the second beam 22 extends inward to form a second flange 221, which corresponds to the positioning ring groove 32. In this way, the second flange 221 blocks the dust collected by the second beam 22 and prevents the dust from escaping from the second beam 22.

[0040] In this embodiment, the connecting portion 2 is a C-shaped structure and also includes a connecting longitudinal beam 23, the two ends of which are respectively connected to the first cross beam 21 and the second cross beam 22 to form a space for accommodating the bearing portion, wherein the connecting longitudinal beam 23 is used to connect to the carrier plate 1.

[0041] Preferably, both ends of the connecting longitudinal beam 23 are respectively vertically connected to the first cross beam 21 and the second cross beam 22 , and the distance between the inner side of the connecting longitudinal beam 23 and the second end surface of the transmission wheel 3 is greater than the distance between the first flange 211 and the limiting wheel rim 31 .

[0042] Such arrangement ensures that even when the bearing part deflects in the space of the connecting part 2, the bearing part will never contact the connecting longitudinal beam 23, so as to ensure that the positioning ring groove 32 and the limiting wheel rim 31 can play a role in correcting and guiding the first cross beam 21, and can rely on the two to correct and guide the carrier plate 1.

[0043] Reference Figure 4 In this embodiment, inclined guide surfaces are provided at both ends of the first cross beam 21. By providing the inclined guide surfaces, the first cross beam 21 of the carrier 1 can smoothly contact the bearing part of the transmission wheel 3 during transmission, and no collision will be caused due to sudden contact, thereby achieving smooth transmission of the carrier 1.

[0044] Reference Figure 3 Furthermore, an anti-slip member 4 is provided on the outer peripheral side of the bearing portion, which is beneficial to increase the friction between the transmission wheel 3 and the carrier plate 1, and ensure that the transmission wheel 3 drives the carrier plate 1 to move.

[0045] In some embodiments, the anti-slip member 4 is an annular rubber ring which is sleeved on the bearing portion.

[0046] Reference Figure 1 The present embodiment further provides a vacuum device, comprising a vacuum chamber 6 and the above-mentioned carrier transport connection device, wherein the transmission wheels 3 of the carrier transport connection device are arranged on two opposite sides of the vacuum chamber 6, and the first crossbeams 21 on both sides of the carrier 1 of the carrier transport connection device are transmission-connected to the transmission wheels 3. Since the vacuum device is provided with the above-mentioned carrier transport connection device, it has all the advantages of the carrier transport connection device, which will not be described in detail here.

[0047] In this embodiment, transmission shafts 5 are disposed on two opposite sides of the vacuum chamber 6 , and the transmission shafts 5 are connected to the first end of the transmission wheel 3 .

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
