Description

Technical Field

[0001] The present invention relates to the field of circuit board processing, and particularly relates to a turning device for circuit board production. Background Art

[0002] A circuit board is also known as a printed circuit board and a PCB board, etc. When classified by the number of layers, it is divided into three major categories: single-sided boards, double-sided boards, and multi-layer circuit boards. Its function can miniaturize and visualize the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances.

[0003] Among them, when processing a circuit board, it is generally fixed by a fixing mechanism, which facilitates people to process its end face. However, when both end faces of the circuit board need to be processed, after one end face is processed, it needs to be removed from the fixing mechanism and flipped and fixed to process the other end, resulting in time-consuming and laborious work and also affecting the processing efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a turning device for circuit board production.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] A turning device for circuit board production, including a base:

[0007] On both sides of the top of the base, there are vertical plates. Between the two groups of vertical plates, there is a U-shaped frame with an upward opening, and both ends of the U-shaped frame are provided with rotating shafts passing through the corresponding vertical plates. On the vertical plates, there is a motor connected to one of the rotating shafts;

[0008] On the inner wall of one vertical end of the U-shaped frame, there is a strip-shaped groove I, and at the other vertical end, there is a locking mechanism. On the inner wall of the horizontal end of the U-shaped frame, there is a strip-shaped groove II communicating with the strip-shaped groove I.

[0022] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the drawings.

[0023] A turning device for circuit board production includes a base 1:

[0024] On both sides of the top of the base 1, there are vertical plates 2. Between two groups of vertical plates 2, there is a C-shaped frame 3 with an upward opening. Both ends of the C-shaped frame 3 are provided with rotating shafts passing through the corresponding vertical plates 2, and on the vertical plate 2, there is a motor 4 connected to one of the rotating shafts;

[0025] On the inner wall of one vertical end of the C-shaped frame 3, there is a strip groove I 5, and at the other vertical end, there is a locking mechanism 6. On the inner wall of the horizontal end of the C-shaped frame 3, there is a strip groove II 7 communicating with the strip groove I 5. In the strip groove I 5 and the strip groove II 7, there are respectively movably fixed a flexible protective strip I 8 and a protective strip II 9 with a C-shaped cross-section, and the opening sizes of the protective strip I 8 and the protective strip II 9 are equal;

[0026] The locking mechanism 6 includes a clamping plate 62 driven by an electric push rod I 61 on one side of the inner bottom of the C-shaped frame 3. On the back of the top of the clamping plate 62, there is a mounting plate 63 for fixing the electric push rod II 64. On the output shaft of the electric push rod II 64, there is a locking plate 65. A T-shaped structure is formed between the clamping plate 62 and the locking plate 65.

[0027] In this embodiment, the electric push rod I 61 is arranged on the outer side wall of the C-shaped frame 3. On the outer side of the C-shaped frame 3, there is also a box body 10 arranged on the same side as the electric push rod I 61, and in the box body 10, there is a battery pack connected to the electric push rod I 61 and the electric push rod II 64 to supply power to them.

[0028] In this embodiment, the protective strip I 8 is arranged in the strip groove I 5, and on the outer side of the C-shaped frame 3, there is a bolt 11 screwed to the back of the protective strip I 8.

[0029] In this embodiment, the protection strip II9 is arranged in the strip-shaped groove II7 near the strip-shaped groove I5. A sliding groove 12 away from the strip-shaped groove I5 is arranged in the middle of the bottom wall of the strip-shaped groove II7 on one side of the protection strip II9. A vertical rod 13 located in the strip-shaped groove II7 is arranged at the bottom of the clamping plate 62. A slider 14 located in the sliding groove 12 is arranged at the bottom end of the vertical rod 13.

[0030] In this embodiment, clamping grooves 15 are arranged on both side walls of the strip-shaped groove I5. Clamping strips 16 embedded in the clamping grooves 15 are arranged on both sides of the protection strip I8. By fixing the clamping strips 16 through the clamping grooves 15, the probability of the protection strip I8 sliding out of the strip-shaped groove I5 is reduced, so as to improve its stability.

[0031] As Figure 2 shown, a plurality of fixing holes are arranged on the bottom end surface of the protection strip II9. Connecting columns 17 embedded in the fixing holes are arranged at the bottom of the strip-shaped groove II7. After the protection strip II9 is embedded in the strip-shaped groove II7, the connecting columns 17 are inserted into the corresponding fixing holes to movably fix the protection strip II9 in the strip-shaped groove II7.

[0032] Usage method of the present invention: Select the corresponding protection strip I8 and protection strip II9 according to the thickness of the circuit board, and fix them in the corresponding strip-shaped groove I5 and strip-shaped groove II7 as shown in Figure 2 , 3 , 4, so as to meet the usage requirements in different situations by replacing the protection strips I8 and protection strips II9 of different specifications;

[0033] During use, the circuit board is placed into the opening of the U-shaped frame 3, and the other end is respectively clamped into the openings of the corresponding protection strip I8 and protection strip II9 for fixation. At the same time, the electric push rod I61 drives the clamping plate 62 to move leftward to abut against the right end of the circuit board to squeeze and fix it. When the clamping plate 62 moves leftward, the electric push rod II64 drives the locking plate 65 to displace to directly above the right end of the circuit board through the mounting plate 63. At this time, the electric push rod II64 drives the locking plate 65 to move downward to play a role in locking and fixing the top end of the circuit board. Thus, while preventing the circuit board from sliding out of the U-shaped frame 3 through the above method, it can also perform the locking and fixing work on circuit boards of different specifications;

[0034] The motor 4 drives the U-shaped frame 3 and the circuit board fixed inside it to rotate 180 degrees clockwise and counterclockwise through the rotating shaft, thereby arbitrarily switching the end face orientation of the circuit board, so that people can conveniently process its different end faces.

[0035] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
