[0002] Copper clad laminate is made by first impregnating electronic glass cloth or other reinforcing materials with resin to make a prepreg, and then covering one or both sides of the prepreg with copper foil and hot pressing, which is simply called copper clad laminate. Usually, the prepreg and copper foil are stacked on a steel plate as a hot pressing unit; then multiple hot pressing units are stacked into a stack and sent into a laminator for hot pressing. In this way, through the support and spacing functions of the steel plate, the copper clad laminate formed after hot pressing is easy to separate and remains flat.

[0003] After separating the copper clad laminate from the steel plate, the steel plate needs to be cleaned. In order to improve the degree of mechanization and automation, our company plans to use a transfer device instead of manual labor to send the steel plate from the separating device to the steel plate cleaning machine. In order to avoid water splashing out and dust entering, the inlet of the steel plate cleaning machine will be adjusted as small as possible; therefore, it is necessary to position the steel plate sent by the transfer device to ensure that the steel plate can be stably and reliably sent into the inlet of the steel plate cleaning machine.

[0027] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.

[0028] The following will Figure 1 ~ Figure 3 describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0029] The embodiment of the present utility model provides a positioning device. The positioning device includes: two sets of front and rear positioning mechanisms and a conveying mechanism for conveying steel plates in the left-right direction. The positioning mechanism includes: a bracket 1, a positioning cylinder 2 installed on the bracket 1, and a power source 3 for driving the bracket 1 to move back and forth. The bracket 1 is provided with a plurality of vertical shafts 4 extending upward in the left-right direction. The positioning cylinders 2 correspond to the vertical shafts 4 one by one and are installed on the corresponding vertical shafts 4 through first bearings. The conveying mechanism includes: a plurality of conveying rollers 5 arranged in the left-right direction and a servo motor 6 for driving the conveying rollers 5 to rotate. The interval between adjacent conveying rollers 5 is greater than the diameter of the positioning cylinder 2 for the positioning cylinder 2 to pass through. It should be understood that the upper end of the positioning cylinder 2 is higher than the top of the conveying roller 5 and the lower end is lower than the top of the conveying roller 5.

[0030] The following describes the specific implementation manner of the positioning device: When the upstream transfer device sends the steel plate to the conveying mechanism of the positioning device; the power source 3 of the positioning mechanism is used to drive the bracket 1 to move, so that the positioning cylinders 2 of the two positioning mechanisms approach each other; the steel plate can be pushed to the middle position between the two positioning mechanisms, thus completing the positioning of the steel plate. Then, the servo motor 6 is used to drive the conveying rollers 5 to rotate to convey the steel plate in the left-right direction, and the steel plate can be sent into the inlet of the steel plate cleaning machine; the power source 3 of the positioning mechanism will drive the bracket 1 to move in the reverse direction, so that the positioning cylinders 2 of the two positioning mechanisms move away from each other to complete the reset. The positioning device has a simple structure and low cost, and can conveniently and quickly position the incoming steel plate to ensure that the steel plate can be stably and reliably sent into the inlet of the steel plate cleaning machine; in this way, the requirement for the installation accuracy of the transfer device can be greatly reduced, which is more convenient.

[0031] Further, the power source 3 is installed on a first cross-frame 7 extending in the left-right direction; the left and right ends of the first cross-frame 7 are respectively installed on a second cross-frame 8 extending in the front-rear direction; the second cross-frame 8 is provided with a first strip-shaped hole 9 extending in the front-rear direction; the first cross-frame 7 is provided with a mounting hole corresponding to the first strip-shaped hole 9 and is adapted to a bolt. It should be understood that with the foregoing structure, the front-rear position of the first cross-frame 7 can be adjusted along the length direction of the second cross-frame 8, so as to adjust the front-rear position of the positioning mechanism, or adjust the distance between the two positioning mechanisms in the front-rear direction. Thus, when the positioning device is installed, the positioning position of the steel plate can be debugged more conveniently; at the same time, in the later stage, it can also be adapted to position steel plates of different sizes according to actual conditions.

[0032] Further, the front and rear ends of the second cross-frame 8 are respectively installed on the top of a first vertical frame 10. It should be understood that the second cross-frame 8 can be welded to the top of the first vertical frame 10, and the first vertical frame 10 can be fixed to the base or the ground.

[0033] Further, the power source 3 is arranged as a linear cylinder. It should be understood that the linear cylinder has the advantages of fast response speed and low cost; it is beneficial to reduce the equipment cost. Of course, according to the requirements of the actual situation, the power source 3 can also be arranged as other driving devices such as a linear motor or an electric push rod.

[0034] Further, the conveying roller 5 is coaxially and fixedly connected with the gear; the gears of the conveying rollers 5 are connected by a transmission chain 11; the servo motor 6 drives the remaining conveying rollers 5 to rotate by driving one of the conveying rollers 5 to rotate.

[0035] Further, the front and rear ends of the conveying roller 5 are respectively installed on a bearing seat 12 through a second bearing; the bearing seat 12 is installed on a third cross-frame 13 extending in the left-right direction; the third cross-frame 13 is installed on the top of a vertical frame 14. It should be understood that the third cross-frame 13 can be welded to the top of the vertical frame 14.

[0036] Further, the vertical frame 14 includes: a second vertical frame 15 and a third vertical frame 16; the third cross-frame 13 is installed on the top of the second vertical frame 15; the second vertical frame 15 is provided with a second strip-shaped hole 17 extending in the up-down direction, and the third vertical frame 16 is provided with a third strip-shaped hole 18 extending in the up-down direction and is adapted to a bolt. It should be understood that with the foregoing structure, the height of the conveying roller 5 can be adjusted flexibly; thus, when the positioning device is installed, the positioning height of the steel plate can be debugged more conveniently. The third vertical frame 16 can be fixed to the base or the ground.

[0037] Further, the first cross-frame 7, the second cross-frame 8, the third cross-frame 13, the first vertical frame 10, the second vertical frame 15, and the third vertical frame 16 are respectively processed from profiles.

[0038] Furthermore, an optical sensor is provided at the incoming material end of the conveying mechanism; the optical sensor, the power source 3, and the servo motor 6 are all controlled by a controller. It should be understood that when the controller monitors the steel plate sent by the upstream transfer device through the optical sensor, it can automatically issue an instruction to make the power source 3 and the servo motor 6 automatically complete the corresponding actions, thereby realizing the automatic positioning and feeding of the steel plate. Common commercially available controllers can meet the requirements, and the structure and principle of the controller will not be elaborated here.

[0039] The embodiment of the present invention also provides a steel plate cleaning machine, which has the aforementioned positioning device.

[0040] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that without departing from the principle and essence of the present invention, various changes or modifications can be made to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.
