Description

Technical Field

[0001] This utility model relates to the field of prepreg production technology, specifically to an automatic staggered stacking device for a prepreg production line. Background Technology

[0002] Prepreg, also known as adhesive sheet or PP sheet, is a semi-finished product of fiberglass board and PCB board. It is mainly composed of resin and fiberglass cloth. After the fiberglass cloth is impregnated with resin, dried and cut, it forms a sheet material with a certain degree of flexibility that can be cured under heat and pressure. It is then conveyed out by a conveyor line for stacking.

[0003] The stacking method of prepregs is affected by the number of layers required for subsequent lamination. For products requiring only single-layer lamination, prepregs can be stacked in an aligned manner, either by an automated stacking device or manually. For multi-layer lamination products, prepregs need to be staggered (approximately 2 inches apart) to facilitate automatic gripping by the jaws during lamination. General-purpose automated stacking devices lack mechanisms for staggering prepregs, so stacking is currently mostly done manually, but efficiency needs improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic staggered stacking device for a prepreg production line. This device can achieve staggered stacking of prepregs based on existing stacking devices, and has the technical characteristics of low cost and ease of use.

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

[0006] An automatic staggered stacking device for a prepreg production line includes a frame, a hydraulic lifting platform installed inside the frame, and a roller assembly installed on top of the hydraulic lifting platform. Guide rails arranged in a front-to-back direction are provided on the left and right sides of the rear side of the frame. A front positioning mechanism and a rear positioning mechanism spanning the frame are mounted on the guide rails via sliders. The front positioning mechanism has a front baffle that moves up and down driven by a cylinder, and the rear positioning mechanism has a rear baffle. A predetermined distance is maintained between the front and rear baffles. A counting sensor for detecting the number of prepregs is provided on the front side of the frame. The counting sensor, the cylinder, and the hydraulic lifting platform are all connected to the control unit of the prepreg production line.

[0007] In a further embodiment, the front positioning mechanism includes a front gantry spanning the frame, a front baffle disposed within the front gantry, at least two optical axes vertically mounted on the front gantry and connected at their lower ends to the front baffle, and a cylinder vertically mounted on the front gantry and connected to the front baffle; the left and right ends of the front gantry are mounted on guide rails on both sides via sliders.

[0008] In a further embodiment, the bottom edge of the front baffle is provided with an adhesive layer.

[0009] In a further embodiment, the rear positioning mechanism includes a rear gantry spanning the frame and a rear baffle fixed on the rear gantry. The left and right ends of the rear gantry are mounted on guide rails on both sides via sliders.

[0010] In a further embodiment, side baffles for limiting movement are provided on the left and right sides of the top of the frame.

[0011] Compared with the prior art, this utility model has the following advantages: Existing stacking devices usually have a rear baffle. This utility model is based on this and is equipped with a liftable front baffle, and there is a certain distance between the front and rear baffles. In this way, the front and rear baffles can alternately limit the rear of the semi-cured sheet groups, thereby realizing the staggered arrangement of adjacent semi-cured sheet groups, meeting the stacking requirements of multi-layer pressed products, and the efficiency is higher than manual stacking. At the same time, when either the front baffle or the rear baffle works alone, it can meet the alignment stacking requirements of single-layer pressed products. This utility model is easy to use and has low modification costs based on existing equipment.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "longitudinal", "lateral", "up", "down", "vertical", "horizontal", "top", "bottom", and "one end" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In this utility model, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 1 As shown, this embodiment provides an automatic staggered stacking device for a prepreg production line, including a frame-type machine, a hydraulic lifting platform 1 installed inside the machine, and a roller assembly installed on top of the hydraulic lifting platform 1. Side baffles 2 for limiting movement are provided on the left and right sides of the top of the machine. An opening is provided on the side of the frame-type machine closest to the prepreg production line (i.e., the side where the prepreg arrives) to avoid affecting the lifting of the hydraulic lifting platform 1. Trays for supporting the prepreg are provided on the roller assembly.

[0023] The rear side of the frame is provided with guide rails 7 arranged in the front-to-back direction on the left and right sides. A front positioning mechanism 5 and a rear positioning mechanism 6 spanning the frame are mounted on the guide rails 7 via sliders 8. Figure 2 As shown, the front positioning mechanism 5 is equipped with a front baffle 53 that is driven by a cylinder 52 to move up and down. Figure 3As shown, a rear baffle 62 is provided on the rear positioning mechanism 6, and a predetermined distance (e.g., 2 inches) is maintained between the front baffle 53 and the rear baffle 62. A counting sensor 3 for detecting the number of prepregs is provided on the front side of the frame. The counting sensor 3, the cylinder 52 and the hydraulic lifting platform 1 are all connected to and controlled by the control machine of the prepreg production line.

[0024] like Figure 2 As shown, the front positioning mechanism 5 includes a front gantry 51 spanning the frame, a front baffle 53 disposed within the front gantry 51, at least two optical axes 55 vertically mounted on the front gantry 51 and connected at their lower ends to the front baffle 53, and a cylinder 52 vertically mounted on the front gantry 51 and connected to the front baffle 53. The left and right ends of the front gantry 51 are mounted on guide rails 7 on both sides via sliders 8. The bottom edge of the front baffle 53 is provided with an adhesive layer 54 to prevent it from damaging the surface of the prepreg when it descends and contacts the lower prepreg.

[0025] The rear positioning mechanism 6 includes a rear gantry 61 spanning the frame and a rear baffle 62 fixed on the rear gantry 61. The left and right ends of the rear gantry 61 are mounted on guide rails 7 on both sides via sliders 8. Normally, the lower edge of the rear baffle 62 should be lower than the lowest point of the prepreg group 4 it is to block, and its upper edge should be higher than the highest point of the prepreg group 4 it is to block.

[0026] The working principle of this utility model is as follows: 1. When this utility model is used for aligning stacks, either the front positioning mechanism 5 or the rear positioning mechanism 6 can participate in blocking the rear edge of the prepreg. 2. As... Figure 4 As shown, when stacking different prepreg groups 4 in staggered layers, if the current group is blocked and limited by the rear baffle 62, the front baffle 53 rises and does not participate in the blocking and limiting. When the counting sensor 3 counts to the number of prepreg layers required for one group, the front baffle 53 descends, and its lower edge approaches or abuts against the topmost prepreg, starting the stacking of the next group. When the counting sensor 3 counts to the number of prepreg layers required for one group again, the front baffle 53 rises, and the rear baffle 62 participates in the stacking of the next group; this process is repeated alternately. During the stacking process, under the control of the controller, the hydraulic lifting platform 1 continuously descends in height as the number of stacks increases, ensuring that the prepreg is received at the same height each time.

[0027] 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.
