[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] In many circuit board manufacturing processes, a transport device is required to complete the transport of the boards. The existing transport device usually consists of multiple parallel transmission shafts, a support plate for supporting and fixing the transmission shafts, and multiple chains, sprockets and guide wheels connected to the transmission shafts. In the transport device, the sprocket is the prime mover, the sprocket drives the transmission shaft to rotate, the transmission shaft drives the guide wheel to rotate, and finally the guide wheel drives the rack and other devices to move.

[0034] The transmission shaft support seat currently used is a simple U-shaped part. There is no bearing position, so no bearing is used. The transmission shaft is in direct contact with the transmission shaft support seat, resulting in sliding friction between the transmission shaft and the support seat, large resistance, unstable transmission, and easy wear, resulting in a short service life.

[0035] To solve the above problems, please refer to Figure 1 and Figure 2 The utility model provides a transmission shaft 20 support seat 10. The transmission shaft 20 support seat 10 includes: a bearing 11, and the bearing 11 includes a first through hole 110a;

[0036] The main body 12 includes a bearing 11 mounting portion and a connecting portion 122 that are connected to each other. The bearing 11 is connected to one end of the bearing 11 mounting portion along the X-axis direction. The bearing 11 mounting portion is penetrated by a second through hole 1211a that is connected to the first through hole 110a along the X-axis direction. The connecting portion 122 is used to connect to the support plate, and the transmission shaft 20 passes through the first through hole 110a and the second through hole 1211a in sequence.

[0037] The technical solution of the utility model converts the sliding friction between the transmission shaft 20 and the support seat into rolling friction by adding a bearing 11, which can reduce resistance, make the transmission more stable, reduce wear, increase service life, and reduce use costs.

[0038] In addition, the support member of the support seat of the existing transmission shaft 20 is made of a whole long plate. Since there is no transmission mechanism between the two adjacent shafts, the support member material is wasted, which makes the total cost of the structure higher. In addition, the structure is large and not compact enough, and it is not flexible to use. The support plate of the utility model is a single-body design and is only used where the transmission shaft 20 is needed to be supported. This can save a lot of material and reduce structural costs. It is also small and compact in structure and can be more flexible in use.

[0039] In one embodiment, please refer to Figure 6 A groove 1221a extending along the Y-axis direction is formed at one end of the connecting portion 122 close to the supporting plate, and the inner wall of the groove 1221a is interference fit with the supporting plate.

[0041] In one embodiment, the connecting portion 122 is provided with a limiting protrusion 1222 extending along the Z-axis direction. The limiting protrusion 1222 is located in the groove 1221a. The limiting protrusion 1222 is used to abut against the groove wall of the limiting groove of the support plate, thereby limiting the displacement of the connecting portion 122 relative to the support plate along the Y-axis direction.

[0042] In this embodiment, in order to prevent the connection part 122 from being displaced relative to the support plate along the Y-axis direction, the connection plate is provided with a limiting protrusion 1222. In other embodiments, blocking pieces can be further provided at both ends of the connection part 122 close to the support plate to prevent the connection part 122 from being displaced relative to the support plate along the Y-axis direction.

[0046] In this embodiment, in order to further fix the bearing 11, a bearing 11 cover is added to better fix the bearing 11 in the bearing 11 mounting portion. At the same time, the bearing 11 cover also plays a role in waterproofing and dustproofing, preventing the bearing 11 from being contaminated and extending the service life of the bearing 11.

[0047] In one embodiment, the bearing 11 cover includes a dustproof portion 132 , which is located at the third through hole 131 a and extends along the X-axis in a direction away from the bearing 11 , and a portion of the transmission shaft 20 is located in the dustproof portion 132 .

[0048] In this embodiment, in order to further prevent the external environment from polluting the bearing 11, the bearing 11 cover is provided with a dustproof portion 132, and the dustproof portion 132 cooperates with the transmission shaft 20 to place the bearing 11 in a closed space, further preventing the external environment from polluting the bearing 11 and increasing the service life of the bearing 11.
