Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, in particular to a positioning device for a lighting circuit board. Background Art

[0002] The circuit board is where electronic components are inserted, so you need to drill holes in it. Choose a drill bit based on the thickness of the component pins. When using a drill, be sure to hold the circuit board steady.

[0003] This requires an auxiliary positioning device to fix the position of the circuit board during the circuit board drilling process to avoid positional deviation of the circuit board during the punching process. Most existing positioning devices fix the position of the circuit board by clamping or squeezing the edge of the circuit board. Under this positioning method, the positioning force points are all distributed on the edge of the circuit board. There is a lack of positioning force points in the middle of the circuit board, which makes the positioning force in the middle and edge of the circuit board uneven. When the drilling equipment drills the circuit board, the edge of the circuit board at the drilling point will bend to a certain extent, while the ability of the edge of the circuit board to bend and deform with the drilling force under the action of the positioning device is low. As a result, after the drilling work, the circuit board is prone to uneven deformation on both sides of the drilled hole. For hard plastics, the uneven deformation may even cause the outer side of the circuit board to break, affecting the matching degree of subsequent assembly. Summary of the Invention

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0067] See also Figures 1-8 The present invention provides a technical solution: a positioning device for a lighting circuit board, comprising a main positioning member 1 capable of clamping the edge of the circuit board, a positioning mechanism, and a moving mechanism capable of driving the positioning mechanism to move horizontally between the main positioning members 1, characterized in that:

[0068] The positioning mechanism includes an upper positioning unit and a lower positioning unit, which are respectively arranged on the upper and lower sides of the circuit board and are symmetrically arranged up and down;

[0069] Both the upper positioning unit and the lower positioning unit include:

[0070] A mounting frame 10, which is provided with two sides and is slidably arranged on the moving mechanism;

[0071] An electric telescopic rod 11 is fixedly mounted on the end of the mounting frame 10 away from the moving mechanism. The electric telescopic rod 11 can apply force vertically to ensure that the pressure can be evenly distributed;

[0072] The clamping ring 18 is a circular ring. When the clamping rings 18 are close to each other and the circuit board is positioned, the corresponding drilling position on the circuit board can be at the center position of the clamping ring 18;

[0073] A force transmission component is provided between the clamping ring 18 and the electric telescopic rod 11. The force transmission component can evenly distribute the force applied by the electric telescopic rod 11 to the clamping ring 18.

[0074] A drilling device 20 is provided in the upper positioning unit, and a drill rod 32 is provided at the lower end of the drilling device 20. The center of the drill rod 32 and the center of the clamping ring 18 are on the same axis;

[0075] A sleeve 28 is provided at the upper end of the lower positioning unit. The center of the sleeve 28 and the clamping ring 18 are always on the same axis. The sleeve 28 can cooperate with the moving mechanism to accurately position the clamping ring 18 so that the clamping ring 18 and the position to be drilled are on the same axis.

[0076] During operation, when drilling a hole in a circuit board, the present invention drives the positioning mechanism to move to the designated drilling position through the moving mechanism (the position of the horizontal movable frame 9 is adjusted by rotating the internal threaded rod 16 in the side movable frame 15, and then the position of the upper drilling plate 24 is adjusted. The upper drilling plate 24 is on the lower surface of the circuit board, and the drilling plate 24 is moved to the position on the circuit board corresponding to the hole to be drilled. The position of the reference hole 26 on the upper drilling plate 24 corresponds to the drilling position one by one. The drilling plate 24 and the clamping ring 18 can both move synchronously with the horizontal movable frame 9, so that the reference hole 26 on the drilling plate 24 can always be on the same axis as the clamping ring 18. Then, the mounting frame 10 moves to drive the clamping ring to move horizontally on the drilling plate 24, and drilling is performed on the lower clamping ring 18. The transfer sleeve 28 is sleeved on the lower connecting tube 27 corresponding to the reference hole 26, thereby ensuring that the reference hole 26 and the clamping ring 18 are on the same axis, and then the reference hole 26 and the drill rod 32 are on the same axis, ensuring the accuracy of the drilling position). The upper positioning unit and the lower positioning unit are close to the circuit board, so that the clamping rings of the upper positioning unit and the lower positioning unit clamp and fix the edge of the drilling position, and the circuit board at the middle position of the clamping ring is drilled through the drill rod 32. During the drilling process, the clamping ring can clamp the edge of the drilling hole and ensure that the clamping position is consistent with the position of the drilling center pad, ensuring that the deformation of the circuit board caused by drilling during the drilling process is consistent, avoiding the situation where the circuit board is broken due to the different deformation of the circuit board at the edge of the drilling hole during the drilling process (such as Figure 8 As shown on the left, in the traditional drilling process, the area actually involved in the deformation around the hole is asymmetric and unbalanced, so the deformation on both sides is also asymmetric. The present invention uses a clamping ring to first form a fixed symmetrical deformation range around the hole, so that the deformation amount is balanced and stable).

[0077] As a further embodiment of the present invention, the force transmission component includes:

[0078] The first connecting rods 19 are provided in multiple groups and are evenly fixedly mounted on the output end of the electric telescopic rod 11. The first connecting rods 19 are spread outward from one end of the electric telescopic rod 11. The first connecting rods 19 can spread the force applied by the electric telescopic rod 11 outward;

[0080] The second connecting rod 21 is provided with multiple groups and is evenly distributed and fixedly installed on the annular intermediate transition ring 17 . The end of the second connecting rod 21 away from the electric telescopic rod 11 is gathered toward the middle and fixedly connected to the clamping ring 18 .

[0081] During operation, the electric telescopic rod 11 drives the upper positioning unit and the lower positioning unit close to the circuit board. During the extrusion process, when the electric telescopic rod 11 applies force, the force is distributed to the intermediate transition ring 17 through the first connecting member, and then the intermediate transition ring 17 and the second connecting rod 21 transmit the force to the clamping ring 18. The double transition of the first connecting rod 19 and the second connecting rod 21 makes the force on the clamping ring 18 more evenly distributed, thereby making the clamping ring 18 clamp and fix the circuit board more evenly distributed, thereby ensuring that the force on the circuit board at the edge of the drilling is more even.

The driven gear 13 rotates to rotate the bottom screw member 8. The screw member 8 rotates through the upper transmission member 7 to drive multiple groups of screw members 8 to rotate simultaneously. The rotation of the screw member 8 interacts with the upper threaded rod 3 to drive the upper threaded rod 3 to move downward), and pushes the movable contact plate 4, so that the movable contact plate 4 contacts and fixes the other end of the circuit board.

[0089] As a further solution of the present invention, the moving mechanism includes a transverse movement mechanism and a longitudinal movement mechanism. The longitudinal movement mechanism is arranged on both sides of the main positioning member 1, and the transverse movement mechanism is slidably arranged between the longitudinal movement mechanisms.

[0095] During operation, the position of the horizontal movable frame 9 is adjusted by rotating the internal threaded rod 16 in the side movable frame 15, and then the position of the upper drilling plate 24 is adjusted. The upper drilling plate 24 is on the lower surface of the circuit board, and the drilling plate 24 is moved to the position on the circuit board corresponding to the position where a hole needs to be drilled. The position of the reference hole 26 on the upper drilling plate 24 corresponds one to one with the drilling position.
