[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] Please refer to 1-6, a single-sided circuit board blanking and edging device, including: a bracket 1, a bogie 4 is arranged above the bracket 1, a rotating rod 8 is rotatably arranged on the bogie 4, the bottom end of the rotating rod 8 is fixedly connected to an air bag 82, a worm gear 9 is fixedly sleeved on the rotating rod 8, a worm 5 is meshed on the worm gear 9, the worm 5 is rotatably arranged on the bogie 4, two push plates 52 are rotatably arranged on the worm 5, an air supply component 6 is fixedly connected to the worm gear 9, and the air supply component 6 is connected to the air bag 82 through a hose 65.

[0026] Specifically, the utility model drives the two push plates 52 to move toward or away from each other through the motor 7, and at the same time, driven by the worm 5, the rotating rod 8 rotates, and the airbag 82 is inflated and deflated, so that the circuit board is rotated ninety degrees and the initial grinding position can be automatically adjusted, so that the device can rotate in situ and correct the position under the drive of a driving source, which greatly shortens the length of the conveying device and avoids the intervention of the cylinder system, that is, greatly reduces the equipment investment cost, reduces the floor space occupied by the equipment installation, and reduces the subsequent maintenance costs.

[0027] Furthermore, the air replenishing component 6 includes a shell 66, in which a fixed rod 61 is rotatably arranged, a cam 62 is fixedly sleeved on the fixed rod 61, a plunger 67 is slidably arranged in the shell 66, the plunger 67 is connected to the inner wall of the shell 66 through a spring 68, and the outer side of the cam 62 abuts against the plunger 67.

[0028] Specifically, refer to Figure 5 and Figure 6The plunger 67 is slidably disposed in the air-filling chamber 64 formed in the housing 66, one end of the spring 68 is fixedly connected to the inner wall of the air-filling chamber 64, and the other end of the spring 68 abuts against the plunger 67. When the fixed rod 61 rotates, the cam 62 pushes the plunger 67 to reciprocate, so that the plunger 67 squeezes the gas in the air-filling chamber 64, so that the gas in the air-filling chamber 64 is squeezed into the airbag 82, so that the airbag 82 abuts against the circuit board after expansion, so that the circuit board and the rotating rod 8 move synchronously.

[0029] Furthermore, a second bevel gear 81 is fixedly sleeved on the outside of the rotating rod 8 , a first bevel gear 63 is fixedly sleeved on the outside of the fixing rod 61 , and the second bevel gear 81 passes through the housing 66 and meshes with the first bevel gear 63 .

[0030] Specifically, the housing 66 is meshed with the first bevel gear 63 , and when the rotating rod 8 rotates, the second bevel gear 81 drives the first bevel gear 63 to rotate, so that the cam 62 drives the plunger 67 to reciprocate.

[0031] Furthermore, two sections of threads 51 with opposite thread directions are provided at symmetrical positions on the worm 5 , and the push plate 52 is threadably sleeved on the threads 51 .

[0032] Specifically, the two sections of thread 51 are respectively located on both sides of the meshing thread on the worm 5, and the thread directions of the two sections of thread 51 are opposite. A push plate 52 is provided on the outer sleeve of the thread 51. The motor 7 drives the worm 5 to rotate, so that the push plate 52 slides toward or away from the thread 51, thereby clamping the circuit board, so that the circuit board that is not placed correctly can be adjusted, ensuring that the circuit board can accurately enter the grinding assembly 2 to grind the edges and corners.

[0033] Furthermore, the airbag 82 is made of hard rubber, and anti-slip grooves are provided on the outer side of the airbag 82 .

[0034] Specifically, by providing anti-skid grooves on the outside of the airbag 82, the friction between the airbag 82 and the circuit board is increased. By using hard rubber material to make the airbag 82, the purpose is also to increase the friction between the airbag 82 and the circuit board.

[0035] Furthermore, a motor 7 is fixedly mounted on the bogie 4 , and an output shaft of the motor 7 is fixedly connected to the worm 5 .

[0036] Specifically, the motor 7 drives the push plate 52 to slide outside the thread 51 to adjust the misplaced circuit board. The motor 7 can also drive the plunger 67 to do reciprocating motion, so that the airbag 82 switches between the inflated and uninflated states. At the same time, the motor 7 can also drive the rotating rod 8 to rotate, so that when the circuit board is abutted by the airbag 82, it rotates synchronously with the rotating rod 8, thereby realizing the side-changing operation of the circuit board.

[0037] Furthermore, a plurality of rollers 3 are rotatably arranged on the bracket 1 .

[0038] Specifically, the circuit board is transported by the roller 3, and the opening and closing of the roller 3 is controlled according to the needs of the equipment.

[0039] In this utility model, reference Figures 1 to 6 The gear ratio of the second bevel gear 81 to the first bevel gear 63 is 2:1. When the second bevel gear 81 rotates one circle, the first bevel gear 63 rotates two circles. First, the motor 7 drives the worm 5 to rotate, and the worm 5 drives the rotating rod 8 to rotate. The first bevel gear 63 is driven to rotate through the second bevel gear 81, so that the plunger 67 reciprocates in the air filling chamber 64. When the rotating rod 8 rotates half a circle, the plunger 67 slides up and down in the air filling chamber 64 to achieve an inflation cycle of the airbag 82. When the rotating rod 8 rotates 45 degrees, the plunger 67 slides a quarter of the stroke. The airbag 82 is in a semi-inflated state at this time, but the airbag 82 is in a semi-inflated state. The friction between the airbag 82 and the circuit board is sufficient to support the circuit board to move synchronously with the airbag 82. When the rotating rod 8 rotates to 135 degrees, the plunger 67 has completed three-quarters of the stroke and is in the sliding stage. The gas in the airbag 82 is gradually decreasing, and the friction between the airbag 82 and the circuit board is insufficient to support the circuit board to move synchronously with the airbag 82. That is, when the rotating rod 8 rotates between 45 degrees and 135 degrees, the circuit board rotates 90 degrees following the airbag 82, completing the side change of the circuit board. At the same time, the circuit board is squeezed and straightened by the push plate 52, so that the circuit board can accurately enter the grinding assembly 2 for the next step of grinding.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
