Detailed implementation manners

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0045] See Figure 1 , when the pressing plate conveying line 200 conveys the pressing plate, two pressing plate conveyor belts 201 respectively bear and convey two sides of the pressing plate; and, a plurality of pressing plates are adjacent to each other and in a continuous conveying state. In some application scenarios, when the foremost pressing plate is conveyed to the pressing plate taking position near the end of the pressing plate conveying line 200, longitudinal alignment of the pressing plate in the conveying direction and lateral alignment perpendicular to the conveying direction (i.e., the left and right directions of the conveying line) are required. During alignment, the pressing plate needs to be separated from the conveyor belt so as to facilitate alignment.

[0046] See Figure 1 , Figure 2 , Figure 3 and Figure 4, in an embodiment of the present application, the press plate alignment device 100 includes: a longitudinal moving seat 1 configured to move back and forth along the extending direction of the press plate conveyor belt 201; two press plate bearing blocks 2 installed on the longitudinal moving seat 1 and respectively used to support two sides of the press plate; the press plate bearing block 2 includes a climbing section and a bearing section, when the press plate conveyor belt 201 drives the press plate forward, the side edge of the press plate climbs along the climbing section of the corresponding press plate bearing block 2 to the bearing section; a first side alignment block 31 and a second side alignment block 32 installed on the longitudinal moving seat 1, and an elastic pushing component 33 is arranged on the first side alignment block 31; when the press plate conveyor belt 201 drives the press plate forward to between the two side alignment blocks, the elastic pushing component 33 is used to press the press plate tightly against the second side alignment block 32.

[0047] In this embodiment, when the press plate conveyor belt 201 drives the press plate forward, the side edge of the press plate climbs along the climbing section of the corresponding press plate bearing block 2 to the bearing section, so as to separate the press plate from the press plate conveyor belt 201; and, after the press plate bearing block 2 climbs to the bearing section, it also enters between the two side alignment blocks at the same time, and the elastic pushing component 33 is used to press the press plate tightly against the second side alignment block 32; in this embodiment, when the elastic pushing component 33 presses the press plate tightly against the second side alignment block 32, the lateral alignment is completed, and then through the forward and backward movement of the longitudinal moving seat 1, the press plate bearing block 2 is driven to move at the same time, so as to realize the longitudinal alignment of the press plate.

[0048] It should be noted that when the side edge of the press plate climbs along the climbing section of the corresponding press plate bearing block 2, the forward driving force can be the friction force of the press plate conveyor belt 201 at the beginning. When continuing to climb, the end of the press plate may have separated from the surface of the press plate conveyor belt 201. At this time, the pushing of the subsequent press plate can be considered for continuous climbing.

[0049] In this embodiment, the top of the press plate bearing block 2 is used to contact the press plate. In order to facilitate the climbing of the press plate, the top of the press plate bearing block 2 can be configured to have a low friction coefficient, and rolling friction is particularly preferred.

[0050] In this embodiment, preferably, the press plate bearing block 2 includes: a block body 21; a plurality of rolling elements 22 for supporting the side edges of the press plate, installed on the upper part of the block body 21; the vertices of the rolling elements 22 on the block body 21 located in the bearing section are higher than the surface of the press plate conveyor belt 201.

[0051] In this embodiment, the rolling element 22 can be, but is not limited to, a ball embedded in the top of the block body 21; of course, in other embodiments, the rolling element 22 can also be a roller, a columnar roller, etc.

[0056] Furthermore, the inner side surface of the second alignment section 322 includes a second guiding inclined surface 3221 and a second clamping surface 3222 opposite to the first guiding inclined surface 3311 and the first clamping surface 3312.

[0057] Referring to Figure 5 and Figure 6 , in this embodiment, the distance between the first guiding section 311 and the second guiding section 321 is greater than the distance between the first clamping surface 3312 and the second clamping surface 3222; when the pressing plate conveyor belt 201 drives the pressing plate to move forward, the pressing plate first enters between the first guiding section 311 and the second guiding section 321 and is preliminarily aligned by both of them; when continuing to move forward, the first side surface of the pressing plate is guided to the first clamping surface 3312 through the first guiding inclined surface 3311, and the second side surface of the pressing plate is guided by the second guiding inclined surface 3221 and the second clamping surface 3222. During this process, the elastic members 332 are gradually compressed, so that the pressing plate is gradually pushed by the top block 331 against the second alignment section 322, and finally is clamped between the first clamping surface 3312 and the second clamping surface 3222 to complete the lateral alignment.

[0058] After completing the lateral alignment, the pressing plate is also lifted off the pressing plate conveyor belt 201 at the same time. By moving the longitudinal moving seat 1 back and forth, the pressing plate bearing block 2 is driven to move at the same time, so as to realize the longitudinal alignment of the pressing plate.
