Description

Technical Field

[0001] This utility model relates to the field of prepreg production technology, specifically to a docking mechanism for a prepreg / fiberglass board transfer vehicle. Background Technology

[0002] Prepreg (also known in the industry as bonding sheet) is an important material for fiberglass boards and copper-clad laminates. In the production workshop, the transfer of prepreg and fiberglass boards is mainly accomplished by transfer carts. The top surface of the transfer cart is equipped with roller sets, and the production equipment (such as laminators) is also equipped with roller conveyor lines. Before lamination, the stacked prepreg is transferred from the transfer cart to the roller conveyor line of the production equipment, realizing the loading operation; after production, the boards are transferred back to the transfer cart via the roller conveyor line, and then the transfer cart is transferred to subsequent process equipment or sent to the shelf.

[0003] During material transfer, it is necessary to maintain the alignment between the transfer cart and the roller conveyor line, and the roller assembly on the transfer cart must remain substantially parallel to the rollers on the conveyor line. Currently, in workshops, workers typically hold the transfer cart in place from behind to prevent it from deviating laterally or completely detaching from the conveyor line during material transfer. The drawbacks are that this method is labor-intensive, and relying solely on manual labor makes it difficult to ensure the transfer cart is always aligned with the conveyor line. Therefore, a new alignment structure needs to be designed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a docking mechanism for a prepreg / fiberglass board transfer vehicle that can remain locked after the transfer vehicle is accurately docked with the roller conveyor line of the production equipment, thus preventing the transfer vehicle from detaching from the roller conveyor line.

[0005] The technical solution of this utility model is:

[0006] A docking mechanism for a prepreg / fiberglass board transport vehicle includes:

[0007] At least two male heads, spherical in shape, are fixed to the front end of the transport vehicle;

[0008] At least two concave holes are set on the rear end face of the roller conveyor line of the equipment to be docked. They are in the shape of a flared mouth that expands outward and allows the male end to extend in, and correspond one-to-one with the male end.

[0009] At least one locating pin hole is provided on the top surface at the rear end of the roller conveyor line;

[0010] At least one positioning plate is fixed to the top surface of the front end of the transfer vehicle, and an oblong hole is provided on it. After the male end is inserted into the concave hole to a predetermined depth, the oblong hole is aligned with the positioning pin hole.

[0011] At least one positioning pin is inserted into the oblong hole and the positioning pin hole after the oblong hole is aligned with the positioning pin hole.

[0012] Preferably, the male head is replaced with a cone, and the top of the cone is rounded.

[0013] Preferably, the front end of the positioning plate is arc-shaped, or the two corners of the front end are rounded.

[0014] Preferably, the length and width of the oblong hole are both greater than the diameter of the locating pin hole.

[0015] Compared with the prior art, this utility model has the following advantages: This utility model uses a spherical male end to connect with a trumpet-shaped concave hole, which can guide the transfer car to be accurately aligned with the roller conveyor line. After alignment, the oval hole on the positioning plate can be accurately aligned with the positioning pin hole. After the positioning pin is inserted, it can effectively prevent the transfer car from falling off and has a certain impact resistance.

[0025] like Figures 1-3 As shown, this embodiment provides a docking mechanism for a prepreg / fiberglass board transfer vehicle, which is mainly used for docking the transfer vehicle 6 with the roller conveyor line 1 of the production equipment, thereby conveying the prepreg to the roller conveyor line 1, or receiving the board material sent by the production equipment. It can also be used for docking the transfer vehicle 6 with equipment such as shelves. The roller assembly of the transfer vehicle 6 is arranged at the same height as the roller conveyor line 1 of the equipment to be docked.

[0026] The docking mechanism includes two male heads 5, two recessed holes 3, two positioning pin holes 2, two positioning plates 4, and two positioning pins 8. The two male heads 5 are spherical and welded to the front end of the frame of the transfer car 6. Generally, one male head 5 is arranged on the left and one on the right side of the frame. The two recessed holes 3 are opened on the rear end of the frame of the roller conveyor line 1. The two recessed holes 3 correspond one-to-one with the male heads 5 and are flared outwards to allow the male heads 5 to extend into them. The maximum diameter and depth of the recessed holes 3 are both greater than the diameter of the male heads 5, so that when the male heads 5 enter the recessed holes 3, they can deviate to a certain extent to the left and right. The inner wall of the flared recessed hole 3 guides the male heads 5, and finally makes the front-back axis of the male heads 5 basically aligned with the front-back axis of the recessed holes 3.

[0027] Two positioning pin holes 2 are opened on the top surface of the rear end of the frame of the roller conveyor line 1. Two positioning plates 4 are fixed on the top surface of the front end of the frame of the transfer car 6. The two positioning plates 4 can be suspended above the frame of the roller conveyor line 1. Each positioning plate 4 has an oblong hole 7. The oblong hole 7 corresponds one-to-one with the positioning pin hole 2. After the male end 5 is inserted into the concave hole 3 to a predetermined depth, the oblong hole 7 is aligned with the positioning pin hole 2.

[0028] Two positioning pins 8 are inserted into the oblong hole 7 and the positioning pin hole 2 after the oblong hole 7 is aligned with the positioning pin hole 2. The positioning plate 4 locks the connection between the transfer car 6 and the roller conveyor line 1. The length and width of the oblong hole 7 are both greater than the diameter of the positioning pin hole 2, which facilitates alignment and the insertion and removal of the positioning pins 8.

[0029] The male head 5 can be replaced with a cone, with the top of the cone rounded to improve safety. Similarly, the front end of the positioning plate 4 can be made into an arc shape, or the two corners of the front end of the positioning plate 4 can be rounded.

[0030] In this embodiment, when in use, the worker pushes the transfer cart 6, and uses the concave hole 3 to guide the male head 5 so that the male head 5 is accurately inserted into the female head, realizing the docking of the transfer cart 6 and the roller conveyor line 1, avoiding the worker to repeatedly perform centering. Then, the positioning pin 8 is inserted into the oblong hole 7 and the positioning pin hole 2 to lock the transfer cart 6 and the roller conveyor line 1.

[0031] The above description is merely a preferred embodiment of this utility model. For those skilled in the art, various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
