Description

Technical Field

[0001] The invention belongs to the technical field of PIN pin bending, in particular to a segmented multi-angle PIN pin bending machine. Background Art

[0002] The finished connector consists of a plastic shell and a PIN pin. Depending on the requirements of different products, the shape of the PIN pin can be straight or bent, but the bent PIN pin is usually bent at 90°, which cannot meet the requirements of special connectors. That is, the PIN pin needs to be bent at different angles according to the special product. In order to meet these requirements, there is an adjustable angle PIN pin bending technology in the prior art, such as the public technical document "CN116060539A, a PIN pin automatic bending device". The mounting plate and the components installed on it are close to the product, and the product pressing block compacts and fixes the connector. Then the auxiliary bending cylinder is pushed out, and then the pushing cylinder is retracted. At this time, the rolling pin connected to the bending rod is positioned below the PIN pin. Next, the auxiliary bending cylinder is retracted. Under the action of the bending angle limit block, the PIN pin is bent to 90 degrees. If the bending angle needs to be adjusted to other degrees, the bending angle of the PIN pin can be adjusted by adjusting the installation position of the adjustment block A and the adjustment block B.

[0003] The above technical solution can meet the multi-angle bending requirements for PIN pins, but there are also shortcomings in the above technical solution. For example, when the PIN pin is relatively short, after the PIN pin is bent by a roller, the PIN pin will have a tendency to reset, resulting in the inability to meet the bending angle. In addition, the above technical solution can only bend the PIN pin once and cannot meet the needs of all products. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Please refer to Figure 1-9 ;

[0032] The PIN bending machine described in the present invention is intended to achieve multi-angle bending and multi-section bending of PIN pins to meet the needs of different products, and specifically includes a frame 1, on which a horizontal moving device 2 and a lifting device 3 are installed. In this embodiment, the specific structures of the horizontal moving device 2 and the lifting device 3 are not limited, but what needs to be achieved is that the two can accurately cooperate with each other in terms of moving distance. Preferably, the horizontal moving device 2 and the lifting device 3 adopt the same structure, such as the cooperation of a servo motor, a screw pair and a slide rail, which can achieve a precise moving distance; a jig 4 is installed on the horizontal lifting device 3 for placing a connector 43, a rotating device 5 is installed on the lifting device 3, and a clamping device 6 is installed on the rotating device 5. The clamping device 6 is used to clamp a plurality of PIN pins, and the clamping end of the clamping device 6 is aligned with the rotation axis centerline;

[0033] During operation, the connector 43 is placed in the fixture 4, and the PIN needle is placed vertically upward. The clamping device 6 is also in a vertical state to clamp several PIN needles. The clamping end of the clamping device 6 corresponds to the position where the PIN needle needs to be bent. At the same time, the position where the PIN needle needs to be bent is aligned with the rotation axis center line. Then the rotating device 5 drives the clamping device 6 to rotate with the axis core line as the center line to complete the bending of the PIN needle. During the bending process, a fulcrum is formed at the end of the clamping device 6 close to the inner side of the bending direction, so that the PIN needle is divided into a fixed part and a bending part. The fixed part maintains the initial state, and the bending part is bent following the rotation of the clamping device 6. There is no need to use an intermediate pad to limit the angle. It can also be applied when the PIN needle is relatively short. The bending angle of the PIN needle can be controlled by the rotating device 5 to meet the needs of different products.

[0034] Based on the above structure, there are many implementation methods. Here, three common bending requirements are listed for illustration. Assume that the length of the PIN is 3 cm.

[0035] In the first embodiment, the PIN needle only needs to be bent once, and the bending angle is 90°. First, the connector 43 is placed in the fixture 4, and the PIN needle is vertically facing upward. The clamping device 6 is also in a vertical state to clamp several PIN needles. In this embodiment, the clamping end of the clamping device 6 is located at 1.5 cm of the PIN needle, and then the rotating device 5 drives the clamping device 6 to rotate 90°. During the bending process, the end of the clamping device 6 is close to the inner side of the bending direction to form a fulcrum, which divides the PIN needle into a 1.5 cm fixed part and a 1.5 cm bent part. One end of the fixed part is fixed to the connector 43, and the bent part rotates 90° with the clamping device 6. Due to the limitation of the fulcrum and the connector 43, the fixed part remains in an upright state, that is, the bent part and the fixed part finally form a 90° angle.

[0036] Embodiment 2: This embodiment is a further expansion of embodiment 1. In this embodiment, the PIN needle is divided into three sections, that is, the PIN needle needs to be bent twice. First, the connector 43 is placed in the fixture 4, and the PIN needle is vertically facing upward. The clamping device 6 is also in a vertical state to clamp several PIN needles. In this embodiment, the clamping end of the clamping device 6 is located at 1 cm of the PIN needle, and then the rotating device 5 drives the clamping device 6 to rotate 90°. During the bending process, the end of the clamping device 6 is close to the inner side of the bending direction to form a fulcrum, and the PIN needle is divided into a first fixed part of 1 cm and a first bent part of 2 cm. One end of the first fixed part is fixed to the connector 43, and the first bent part rotates 90° following the clamping device 6. Due to the limitation of the fulcrum and the connector 43, the first fixed part remains in an upright state, that is, the first bent part finally forms a 90° with the first fixed part.

[0037] Then the clamping device 6 loosens the first bent part, and the horizontal moving device 2 drives the fixture 4 to move backward 1 cm, that is, the end of the clamping device 6 corresponds to 2 cm of the total length of the PIN needle, that is, 1 cm of the first bent part. Then the clamping device 6 clamps the PIN needle again, and uses the end of the clamping device 6 as the boundary to form the first bent part into a second fixed part and a second bent part. Then the rotating device 5 drives the clamping device 6 to rotate 90° in the opposite direction. The relative position of the new fulcrum formed in this process remains unchanged with the first bending point, so the position of the second fixed part remains unchanged, and the second bent part follows the clamping device 6 to rotate 90° in the opposite direction, so that the PIN needle forms a vertical "Z" shape.

[0038] Example 3, refer to Figure 6-9 This embodiment is based on another bending method of the second embodiment. In this embodiment, the PIN needle is divided into three sections, that is, the PIN needle needs to be bent twice.

[0039] First, put the connector 43 into the fixture 4, and make the PIN needle face vertically upward. The clamping device 6 is also in a vertical state to clamp several PIN needles. In this embodiment, the clamping end of the clamping device 6 is located at 1 cm of the PIN needle. Then the rotating device 5 drives the clamping device 6 to rotate 45°. During the bending process, the end of the clamping device 6 is close to the inner side of the bending direction to form a fulcrum, which divides the PIN needle into a 1 cm first fixed part and a 2 cm first bent part. One end of the first fixed part is fixed to the connector 43, and the first bent part rotates 45° with the clamping device 6. Due to the limitation of the fulcrum and the connector 43, the first fixed part is kept in an upright state, that is, the first bent part forms a 45° with the first fixed part.

[0040] Then the clamping device 6 loosens the first bending part, the horizontal moving device 2 drives the fixture 4 to retreat, and at the same time the lifting device 3 drives the rotating device 5 to lift up, so that the clamping device 6 and the PIN needle can slide correspondingly, and finally the end of the clamping device 6 corresponds to 2 cm of the total length of the PIN needle, that is, 1 cm of the first bending part, and then the clamping device 6 clamps the PIN needle again, and uses the end of the clamping device 6 as the boundary to form the first bending part into a second fixed part and a second bending part, and then the rotating device 5 drives the clamping device 6 to rotate 45° in the same direction. The relative position of the new fulcrum formed in this process remains unchanged with the first bending point, so the position of the second fixed part remains unchanged, and the second bending part follows the clamping device 6 to rotate 45° in the opposite direction, so that the second fixed part forms a 45° bend with the first fixed part, the second fixed part forms a 45° bend with the second bending part, and the second bending part forms a 90° bend with the first fixed part.

[0041] The above three embodiments only list three conventional usage methods, especially with reference to Embodiment 2 and Embodiment 3. By adjusting the angle of the rotating device 5, and the horizontal moving device 2 drives the fixture 4 to move and the lifting device 3 drives the rotating device 5 to rise, the relative sliding of the clamping device 6 and the PIN needle is realized, and the PIN needle can be bent at any angle, and is not limited to three bending sections, to meet different customization needs.

[0042] One embodiment of the rotating device 5 of the present invention specifically includes a movable plate 51, which is connected to the lifting device 3, and a driving assembly 52 and two extension plates 53 are installed on the movable plate 51. The output end of the driving assembly 52 is connected to a rotating shaft 1 54. It should be noted that a connecting seat is provided on the movable plate 51, and the connecting seat is rotatably connected to the rotating shaft 1 54. Two synchronous wheels 1 55 are fixed on the rotating shaft 1 54. A rotating frame 56 is rotatably connected between the two extension plates 53. The clamping device 6 is installed on the rotating frame 56. Rotating shafts 2 57 are provided on both sides of the rotating frame 56 and pass through the extension plates 53. A synchronous wheel 2 58 is provided on the rotating shaft 2 57, and the synchronous wheel 2 58 is connected to the synchronous wheel 1 55 through a belt;

[0043] During operation, the driving motor drives the rotating shaft 1 54 to rotate, and the two synchronous wheels 1 55 located on the rotating shaft 1 54 rotate synchronously, which is then rotated through the belt-type synchronous wheel 2 58, and finally drives the rotating shaft 2 57 and the rotating frame 56 to rotate, and the rotating frame 56 synchronously drives the clamping device 6 to rotate, and the clamping end of the clamping device 6 is aligned with the axis connecting the two rotating shafts 2 57, that is, the end of the clamping device 6 always maintains the same position, and only the rotation angle changes.

[0044] One of the embodiments of the clamping device 6 of the present invention specifically includes a fixed splint 61 and a cylinder 62. In this embodiment, the fixing method of the fixed splint 61 and the cylinder is not limited, as long as the installation can be achieved. A movable splint 63 is provided on the opposite side of the fixed splint 61, and a connecting block 64 is provided on one side of the movable splint 63. A movable hole 65 is provided in the connecting block 64, and a fixed shaft 663 is provided in the movable hole 65; a movable block 661 is connected to the output end of the cylinder 62, and the movable block 661 is placed in the movable hole 65, and an inclined groove 662 is provided in the movable block 661, and the inclined groove 662 is connected to the fixed shaft 663. The movable block 661 is driven to move in the movable block 661 through the telescopic action of the cylinder 62, so that the fixed shaft 663 can move along the inclined groove 662, so that the movable splint 63 and the fixed splint 61 are fitted and separated. The structure is simple and the action steps are few, and rapid action can be achieved.

[0045] Furthermore, a plurality of card slots 67 are provided on one side of the fixed clamp plate 61, and the width of the card slot 67 is slightly larger than the width of the PIN needle. Before the clamping device 6 descends to clamp the PIN needle, the PIN needle will first enter the card slot 67, and then the movable clamp plate 63 will fit with the fixed clamp plate 61, which can prevent the PIN needle from being displaced during the bending process.

[0046] The clamping device 6 further includes a fixing block 681, which is mounted on the rotating frame 56. A slot 682 is formed between the fixing block 681 and the rotating frame 56. One end of the fixing clamp 61 is inserted into the slot 682 and connected to the fixing clamp 61 through the rotating frame 56 via a fixing member 69.

[0047] In actual production, the width and length of the PIN are somewhat different, so the fixed splint 61 and the movable splint 63 cannot adapt to all PIN pins. Therefore, a replacement function is provided to meet production needs. More specifically, by removing the fixing part 69 and contacting the limitation on the fixed splint 61, the fixed splint 61 can be pulled out of the slot 682 at this time, and then replaced with another fixed splint 61, and finally connected and fixed to the fixed splint 61 through the fixing part 69 through the rotating frame 56.

[0048] In one embodiment of the fixture 4 of the present invention, referring to Figure 5 , specifically including a base 41, on which a cylinder 2 42 is installed, a connector 43 is provided at the output end of the cylinder 2 42, the connector 43 is rotatably connected to the bottom of a fixing frame 44, and both sides of the fixing frame 44 are rotatably connected to the base 41, and the fixing frame 44 is in a "7" shape. When loading, the connector 43 is pulled back by the cylinder 2 42 to rotate the fixing frame 44 to form an inclined state, and then the connector 43 is placed on the base 41, and the connector 43 is limited by the block 46, and then the cylinder head 2 pushes the connector 43 out to rotate the fixing frame 44, and an avoidance position 45 is provided at the upper end of the fixing frame 44 to avoid contact with the PIN needle. After the fixing frame 44 returns to its initial state, the bottom surface of the upper end of the fixing frame 44 conflicts with the end surface of the connector 43, and cooperates with the block 46 to fix the position of the connector 43 so that it will not move during the bending operation.

[0049] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementations that can be understood by those skilled in the art.
