Description

Technical Field

[0001] This invention relates to the technical field of embedding two annular circuit boards within a printed circuit board, and in particular to an apparatus and method for embedding an annular circuit board within an annular groove of a printed circuit board. Background Technology

[0002] A batch of printed circuit boards 1 produced in a certain workshop have the following structure: Figures 1-3 As shown, a first annular groove 2 and a second annular groove 3 are respectively provided on the two large end faces of the printed circuit board 1. The first annular groove 2 and the second annular groove 3 are symmetrical about the printed circuit board 1.

[0003] The manufacturing process requires that a [device] be embedded in both the first annular groove 2 and the second annular groove 3 of the printed circuit board 1. Figures 4-5 The annular circuit board 4 shown has an outer dimension slightly larger than the size of the annular groove. When installed, the resulting composite circuit board structure is as follows: Figures 6-7 As shown, the two annular circuit boards 4 are respectively interference-fitted with the first annular groove 2 and the second annular groove 3. This type of composite circuit board integrates more circuits and transmits data faster, and is widely used in the control cabinets of CNC machine tools.

[0004] The method by which the workers in the workshop embed a ring-shaped circuit board 4 into each of the two annular grooves of the printed circuit board 1 is as follows:

[0005] S1. The worker takes out a printed circuit board 1, places it on the machine table with the first annular groove 2 facing upwards, as shown. Figure 8 As shown;

[0006] S2. The worker takes out a ring-shaped circuit board 4 and supports the ring-shaped circuit board 4 on the top surface of the first ring-shaped groove 2, as follows. Figure 9 As shown;

[0007] S3. The worker adjusts the position of the printed circuit board 1 so that the right side of the annular circuit board 4 is directly below the strip head 5 of the press; then the worker controls the strip head 5 of the press to move downward, and the strip head 5 impacts the right side of the annular circuit board 4 downward, in the direction of impact as follows. Figure 10 As shown by the middle arrow, under impact, the right side of the annular circuit board 4 is interference-fitted into the first annular groove 2.

[0008] S4. The worker repeats step S3 three times to embed the other three sides of the annular circuit board 4 into the first annular groove 2, thus achieving the embedding of an annular circuit board 4 into the first annular groove 2 of the printed circuit board 1. Figure 11 As shown;

[0009] S5. The worker flips printed circuit board 1 180 degrees, as follows: Figure 12 As shown, the second annular groove 3 is oriented upwards, and then steps S2 to S4 are repeated once, thereby embedding an annular circuit board 4 in each of the second annular grooves 3 of the printed circuit board 1. This ultimately results in embedding an annular circuit board 4 in both annular grooves of the printed circuit board 1, thus obtaining a desired composite circuit board. The structure of the composite circuit board is as follows... Figures 6-7 As shown;

[0010] S6. The worker repeats steps S1 to S5 multiple times to embed two ring circuit boards 4 in multiple printed circuit boards 1, thereby obtaining multiple composite circuit boards.

[0011] However, although the method used in the workshop can embed a ring circuit board 4 in both annular grooves of the printed circuit board 1, the following technical defects still emerge in actual operation:

[0012] I. In steps S3 to S4, the worker needs to perform a total of four processes to embed the four sides of the annular circuit board 4 into the first annular groove 2 respectively. This undoubtedly increases the time required to embed the annular circuit board 4, thereby reducing the efficiency of embedding the annular circuit board 4 in the printed circuit board 1.

[0013] II. In steps S3 to S5, it is known that after a ring circuit board 4 is embedded in the first annular groove 2 of the printed circuit board 1, the worker needs to flip the printed circuit board 1 over before a second ring circuit board 4 can be embedded in the second annular groove 3 of the printed circuit board 1, so as to obtain the required composite circuit board. This undoubtedly further increases the time used to embed the ring circuit board 4, further reduces the efficiency of embedding the ring circuit board 4 in the printed circuit board 1, and thus reduces the output of composite circuit boards.

[0014] Therefore, there is an urgent need for a device and method to greatly improve the efficiency of embedding ring circuit boards in printed circuit boards and increase the output of composite circuit boards. Summary of the Invention

[0015] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device and method for embedding an annular circuit board in an annular groove of a printed circuit board.

[0016] The objective of this invention is achieved through the following technical solution: a device for embedding an annular circuit board in an annular groove of a printed circuit board, comprising a base plate and a strip-shaped positioning seat fixed on the top surface of the base plate. The top surface of the strip-shaped positioning seat is provided with a longitudinally arranged strip-shaped positioning groove, which matches the outer contour of the lower end of the printed circuit board. Vertical plates are fixed on the base plate and on the left and right sides of the strip-shaped positioning seat. A horizontal lead screw module is provided between the two vertical plates. The two threaded seats of the horizontal lead screw module are respectively located on the left and right sides of the strip-shaped positioning seat, and a first embedding component and a second embedding component are respectively provided on the two threaded seats. The structure of the first embedding component is the same as that of the second embedding component.

[0017] The first mounting assembly includes a U-shaped piece fixed to the bottom surface of the threaded seat on the left side, a connecting plate connected to the U-shaped piece, a pushing cylinder fixed to the left end face of the connecting plate, the piston rod of the pushing cylinder passing through the connecting plate to the right, and a pushing seat fixed to the extended end, a blind groove opened on the right end face of the pushing seat, a floating plate that cooperates with it slidably installed in the blind groove, a plurality of springs fixed between the left end face of the floating plate and the bottom of the blind groove, a floating positioning frame that slidably cooperates with the blind groove fixed to the right end face of the floating plate, the right end of the floating positioning frame extending to the right outside the pushing seat, and the outer contour of the floating positioning frame cooperating with the hollow cavity of the annular circuit board.

[0018] The horizontal lead screw module includes a bidirectional lead screw rotatably mounted between two vertical plates, a servo motor fixed on the outer wall of the right vertical plate, and a guide rod fixed between the two vertical plates. Both the forward and reverse external threads of the bidirectional lead screw are threaded with threaded seats. Guide sleeves are fixed on the top surfaces of the two threaded seats, and the guide holes of the guide sleeves are fitted onto the guide rod.

[0019] The floating positioning frame has a weight reduction cavity.

[0020] Two springs are fixed between the floating plate and the bottom of the blind groove, with the two springs located at the upper and lower ends of the floating plate, respectively.

[0021] The connecting plate is inserted into the U-shaped groove of the U-shaped component, and a locking screw is fixed between the U-shaped component and the connecting plate to fix the connecting plate on the U-shaped component.

[0022] The first mounting component and the second mounting component are symmetrical about the strip positioning seat.

[0023] The device also includes a controller, which is electrically connected to the servo motor and the push cylinder via signal lines.

[0024] A method for mounting a ring-shaped circuit board within an annular groove on a printed circuit board, comprising the following steps:

[0025] S1. Positioning the printed circuit board: The worker takes out a printed circuit board and inserts the lower end of the printed circuit board into the strip positioning groove of the strip positioning seat from top to bottom. Since the strip positioning groove matches the outer contour of the lower end of the printed circuit board, the printed circuit board is positioned. At this time, the first annular groove of the printed circuit board is exactly opposite to the push seat of the first mounting component, and at the same time, the second annular groove of the printed circuit board is exactly opposite to the push seat of the second mounting component.

[0026] S2. Position the two ring-shaped circuit boards. The specific operation steps are as follows:

[0027] S21. The worker removes two ring-shaped circuit boards;

[0028] S22. The hollow cavity of a ring circuit board is fitted from right to left onto the extension end of the floating positioning frame of the first mounting component, and the ring circuit board is pressed against the right end face of the push seat, thereby positioning the first ring circuit board on the first mounting component. At this time, the ring circuit board is exactly opposite to the first annular groove of the printed circuit board.

[0029] S23. The worker repeats step S22 once to position the second ring circuit board on the second mounting assembly. At this time, the second ring circuit board is exactly opposite to the second ring groove of the printed circuit board, thus finally completing the positioning of the two ring circuit boards.

[0030] S3. Clamp the printed circuit board:

[0031] The worker controls the servo motor to start, and the servo motor drives the bidirectional lead screw to rotate around its own axis. The two threaded seats on the bidirectional lead screw move in opposite directions, thereby driving the first mounting component and the second mounting component to move in opposite directions, and then driving the two ring circuit boards to move towards the printed circuit board.

[0032] After the servo motor has been running for a period of time, the floating positioning frame of the first mounting component just comes into contact with the left end face of the printed circuit board, and at the same time, the floating positioning frame of the second mounting component just comes into contact with the right end face of the printed circuit board.

[0033] As the servo motor continues to run, the floating positioning frame of the first mounting component moves to the left relative to the stationary printed circuit board. The floating positioning frame drives the floating plate to move to the left relative to the stationary printed circuit board, and the floating plate gradually compresses the spring to the left. At the same time, the floating positioning frame of the second mounting component moves to the right relative to the stationary printed circuit board. The floating positioning frame drives the floating plate to move to the right relative to the stationary printed circuit board, and the floating plate gradually compresses the spring to the right.

[0034] When the servo motor reaches the set time point, the controller controls the servo motor to turn off. At this time, the printed circuit board is clamped between the floating positioning frame of the first mounting component and the floating positioning frame of the second mounting component. The annular circuit board on the first mounting component is aligned with the first annular groove of the printed circuit board, and the annular circuit board on the second mounting component is aligned with the second annular groove of the printed circuit board.

[0035] S4. The worker controls the piston rod of the push cylinder of the first mounting assembly to extend to the right. The piston rod drives the push seat to move to the right relative to the stationary floating positioning frame. The push seat pushes the annular circuit board to move to the right synchronously relative to the stationary floating positioning frame. After the piston rod of the push cylinder extends to the right a certain distance, the annular circuit board positioned on the first mounting assembly is thus mounted into the first annular groove of the printed circuit board.

[0036] At the same time, the worker controls the piston rod of the push cylinder of the second mounting component to extend to the left. After the piston rod of the push cylinder extends to the left a certain distance, the annular circuit board positioned on the second mounting component can be embedded into the second annular groove of the printed circuit board. In this way, an annular circuit board is finally embedded in both annular grooves of the printed circuit board, and a required composite circuit board is obtained.

[0037] S5. Removal of composite printed circuit board: The worker controls the servo motor to reverse, the output shaft of the servo motor drives the bidirectional lead screw to reverse, the bidirectional lead screw drives the two threaded seats to move in opposite directions, thereby driving the first mounting component and the second mounting component to move in opposite directions, thus separating the floating positioning frame and the push seat from the composite circuit board.

[0038] When the servo motor reaches the set time point, the controller controls the servo motor to turn off, and then the worker removes the produced composite circuit board from the strip positioning seat.

[0039] S6. Workers repeat steps S1 to S5 multiple times to embed two ring circuit boards in multiple printed circuit boards, thus obtaining multiple composite circuit boards.

[0040] The present invention has the following advantages: it greatly improves the efficiency of embedding ring circuit boards in printed circuit boards and increases the output of composite circuit boards. Attached Figure Description

[0072] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0073] like Figures 13-20As shown, a device for embedding an annular circuit board in an annular groove of a printed circuit board includes a base plate 6 and a strip-shaped positioning seat 7 fixed on the top surface of the base plate 6. The top surface of the strip-shaped positioning seat 7 has a longitudinally arranged strip-shaped positioning groove 8, which matches the outer contour of the lower end of the printed circuit board 1. Vertical plates 9 are fixed on the base plate 6 and on the left and right sides of the strip-shaped positioning seat 7. A horizontal lead screw module is arranged between the two vertical plates 9. The two threaded seats 10 of the horizontal lead screw module are located on the left and right sides of the strip-shaped positioning seat 7, respectively. A first embedding component 11 and a second embedding component 12 are respectively arranged on the two threaded seats 10. The structure of the first embedding component 11 is the same as that of the second embedding component 12. The first embedding component 11 and the second embedding component 12 are symmetrical about the strip-shaped positioning seat 7.

[0074] The first mounting assembly 11 includes a U-shaped part 13 fixed on the bottom surface of the threaded seat 10 on the left side, and a connecting plate 14 connected to the U-shaped part 13. A push cylinder 15 is fixed on the left end face of the connecting plate 14. The piston rod of the push cylinder 15 passes through the connecting plate 14 to the right, and a push seat 16 is fixed on the extended end. A blind groove 17 is opened on the right end face of the push seat 16. A floating plate 18 that cooperates with it is slidably installed in the blind groove 17. A plurality of springs 19 are fixed between the left end face of the floating plate 18 and the bottom of the blind groove 17. A floating positioning frame 20 that slidably cooperates with the blind groove 17 is fixed on the right end face of the floating plate 18. The right end of the floating positioning frame 20 extends to the right outside the push seat 16. The outer contour of the floating positioning frame 20 cooperates with the hollow cavity of the annular circuit board 4. The connecting plate 14 is inserted into the U-shaped groove of the U-shaped member 13, and a locking screw is fixed between the U-shaped member 13 and the connecting plate 14 to fix the connecting plate 14 on the U-shaped member 13.

[0075] The horizontal lead screw module includes a bidirectional lead screw 21 rotatably mounted between two vertical plates 9, a servo motor 22 fixed on the outer wall of the right vertical plate 9, and a guide rod 23 fixed between the two vertical plates 9. The bidirectional lead screw 21 has threaded seats 10 threadedly connected to both the forward and reverse external threads. Guide sleeves 24 are fixedly provided on the top surfaces of the two threaded seats 10, and the guide holes of the guide sleeves 24 are fitted onto the guide rod 23.

[0076] A weight-reducing cavity is provided inside the floating positioning frame 20. Two springs 19 are fixed between the floating plate 18 and the bottom of the blind groove 17, and the two springs 19 are located at the upper and lower ends of the floating plate 18, respectively.

[0077] The device also includes a controller, which is electrically connected to the servo motor 22 and the push cylinder 15 via signal lines. The operator can control the servo motor 22 to start or stop, and at the same time, control the extension or retraction of the piston rod of the push cylinder 15, thereby facilitating the operator's operation.

[0078] A method for mounting a ring-shaped circuit board within an annular groove on a printed circuit board, comprising the following steps:

[0079] S1. Positioning of printed circuit board 1: The worker takes out a... Figures 1-3 The printed circuit board 1 shown is inserted from top to bottom into the strip positioning groove 8 of the strip positioning seat 7. Since the strip positioning groove 8 matches the outer contour of the lower end of the printed circuit board 1, positioning of the printed circuit board 1 is achieved. Figure 21 As shown, at this time, the first annular groove 2 of the printed circuit board 1 is exactly opposite to the push seat 16 of the first mounting component 11, and at the same time, the second annular groove 3 of the printed circuit board 1 is exactly opposite to the push seat 16 of the second mounting component 12.

[0080] S2. Position the two ring circuit boards 4. The specific operation steps are as follows:

[0081] S21, The worker took out two such... Figures 4-5 The circular circuit board 4 shown;

[0082] S22. A hollow cavity of a ring-shaped circuit board 4 is fitted onto the extension end of the floating positioning frame 20 of the first mounting assembly 11 from right to left, and the ring-shaped circuit board 4 is pressed against the right end face of the push seat 16, thereby positioning the first ring-shaped circuit board 4 on the first mounting assembly 11. Figure 22 As shown, at this time, the annular circuit board 4 is exactly opposite to the first annular groove 2 of the printed circuit board 1.

[0083] S23. The worker repeats step S22 once to position the second annular circuit board 4 on the second mounting assembly 12, as follows: Figure 23 As shown, at this time, the second annular circuit board 4 is exactly opposite to the second annular groove 3 of the printed circuit board 1, thus finally completing the positioning of the two annular circuit boards 4.

[0084] S3. Clamp the printed circuit board 1:

[0085] The worker controls the servo motor 22 to start, and the servo motor 22 drives the bidirectional lead screw 21 to rotate around its own axis. The two threaded seats 10 on the bidirectional lead screw 21 move in opposite directions, thereby driving the first mounting component 11 and the second mounting component 12 to move in opposite directions, and then driving the two ring circuit boards 4 to move toward the printed circuit board 1.

[0086] After the servo motor 22 has been running for a period of time, the floating positioning frame 20 of the first mounting component 11 comes into contact with the left end face of the printed circuit board 1, as shown below. Figure 24As shown, at the same time, the floating positioning frame 20 of the second mounting component 12 is in contact with the right end face of the printed circuit board 1.

[0087] As the servo motor 22 continues to run, the floating positioning frame 20 of the first mounting component 11 moves to the left relative to the stationary printed circuit board 1. The floating positioning frame 20 drives the floating plate 18 to move to the left relative to the stationary printed circuit board 1, and the floating plate 18 gradually compresses the spring 19 to the left. At the same time, the floating positioning frame 20 of the second mounting component 12 moves to the right relative to the stationary printed circuit board 1. The floating positioning frame 20 drives the floating plate 18 to move to the right relative to the stationary printed circuit board 1, and the floating plate 18 gradually compresses the spring 19 to the right.

[0088] When the servo motor 22 reaches the set time point, the controller controls the servo motor 22 to turn off. At this time, the printed circuit board 1 is just clamped between the floating positioning frame 20 of the first mounting component 11 and the floating positioning frame 20 of the second mounting component 12. Figure 25 As shown, the annular circuit board 4 on the first mounting assembly 11 is aligned with the first annular groove 2 of the printed circuit board 1, and at the same time, the annular circuit board 4 on the second mounting assembly 12 is aligned with the second annular groove 3 of the printed circuit board 1.

[0089] S4. The worker controls the piston rod of the push cylinder 15 of the first mounting assembly 11 to extend to the right. The piston rod drives the push seat 16 to move to the right relative to the stationary floating positioning frame 20. The push seat 16 pushes the annular circuit board 4 to move to the right synchronously relative to the stationary floating positioning frame 20. After the piston rod of the push cylinder 15 extends to the right a certain distance, the annular circuit board 4 positioned on the first mounting assembly 11 is thus mounted into the first annular groove 2 of the printed circuit board 1. Figure 26 As shown:

[0090] Simultaneously, the worker controls the piston rod of the push cylinder 15 of the second mounting assembly 12 to extend to the left. After the piston rod of the push cylinder 15 extends to the left a certain distance, the annular circuit board 4 positioned on the second mounting assembly 12 can be mounted into the second annular groove 3 of the printed circuit board 1. Figure 26 As shown, this ultimately resulted in the embedding of a ring-shaped circuit board 4 in each of the two annular grooves of the printed circuit board 1, thus obtaining a desired composite circuit board. The structure of the composite circuit board is as follows: Figures 6-7 As shown;

[0091] As can be seen from steps S1 to S4, the worker only needs to first position the printed circuit board 1 in the strip positioning seat 7; then the worker positions the two annular circuit boards 4 on the first mounting component 11 and the second mounting component 12 respectively; then the worker controls the servo motor 22 to start, so that the printed circuit board 1 is clamped between the floating positioning frame 20 of the first mounting component 11 and the floating positioning frame 20 of the second mounting component 12; then the worker controls the piston rods of the pushing cylinders 15 of the first mounting component 11 and the second mounting component 12 to extend, so that the two annular circuit boards 4 are respectively embedded into the first annular groove 2 and the second annular groove 3 of the printed circuit board 1, thus finally realizing the embedding of two annular circuit boards 4 in the printed circuit board 1, and obtaining the required composite circuit board.

[0092] Therefore, it can be seen that this device, through the cooperation of the servo motor 22, the first mounting component 11, and the second mounting component 12, can automatically and simultaneously embed the two annular circuit boards 4 into the first annular groove 2 and the second annular groove 3 of the printed circuit board 1, respectively. Compared to... Figures 8-12 The mounting method shown eliminates the need for workers to embed two annular circuit boards 4 into the first annular groove 2 and the second annular groove 3 of the printed circuit board 1 in two separate processes. This shortens the time required to mount the annular circuit boards 4 into the printed circuit board 1, thereby greatly improving the efficiency of mounting the annular circuit boards 4 into the printed circuit board 1 and consequently increasing the output of composite circuit boards.

[0093] Furthermore, in step S4, the worker only needs to control the piston rod of the push cylinder 15 to extend, which allows all four sides of the annular circuit board 4 to be embedded into the annular groove of the printed circuit board 1 in one go, compared to... Figures 8-12 The mounting method shown eliminates the need for workers to perform four steps to embed the four sides of the annular circuit board 4 into the annular grooves, thereby shortening the mounting time of the annular circuit board 4 and further improving the efficiency of mounting the annular circuit board 4 in the printed circuit board 1.

[0094] S5. Removal of composite printed circuit board 1: The worker controls the servo motor 22 to reverse, the output shaft of the servo motor 22 drives the bidirectional lead screw 21 to reverse, the bidirectional lead screw 21 drives the two threaded seats 10 to move in opposite directions, thereby driving the first mounting component 11 and the second mounting component 12 to move in opposite directions, thereby causing the floating positioning frame 20 and the push seat 16 to separate from the composite circuit board.

[0095] When the servo motor 22 reaches the set time point, the controller controls the servo motor 22 to turn off. Then, the worker removes the produced composite circuit board from the strip positioning seat 7, in the direction of removal as follows: Figure 27 As shown;

[0096] S6. The worker repeats steps S1 to S5 multiple times to embed two ring circuit boards 4 in multiple printed circuit boards 1, thereby obtaining multiple composite circuit boards.
