Description

Technical Field

[0001] The utility model relates to the field of electrical connectors, in particular to a structure of a material taking manipulator for a plastic body of an electrical connector. Background Art

[0002] An electrical connector generally serves as an input and output connection port of a main board of electronic devices such as a computer and a server. The electrical connector is welded on a printed circuit board and is used for power access and signal transmission after plugging of chips such as a memory and a graphics card. An electrical connector generally consists of an insulating plastic body and contact terminals installed in the plastic body. Besides being used for installing the contact terminals to achieve insulation between the contact terminals, the plastic body can also shield high-frequency signals between adjacent terminals.

[0003] The plastic body of the electrical connector is generally injection molded in a molding die. In order to improve the production efficiency of the plastic body, each mold of the plastic mold can simultaneously inject 8 or 16 plastic bodies. After the plastic bodies are demolded, a material taking manipulator structure is used to simultaneously take out multiple plastic bodies and a sprue from the mold, and the manipulator is used to send the bodies to a specified position.

[0004] During the process of plastic injection molding, considering the fluidity of raw materials in the mold, the structural characteristics of plastic products, and the minimum design of the sprue amount, for an injection mold of a slender plastic body, the mold cavities corresponding to the plastic bodies are circumferentially distributed around the injection port, resulting in different angles of the formed plastic bodies, which are difficult to be stacked in different cavities after demolding, increasing the difficulty of subsequent packaging. Summary of the Invention

[0005] In order to facilitate the grasping and stacking in different cavities of the plastic body after injection molding, the utility model provides a structure of a material taking manipulator for a plastic body of an electrical connector.

[0006] The technical solution adopted by the utility model is as follows:

[0007] The structure of the plastic body picking manipulator for the electrical connector includes a mounting plate. A robotic arm is connected to the center position at the rear side of the mounting plate. A material head grasping device and four plastic grasping devices are installed on the front side of the mounting plate. The material head grasping device is located at the center position on the front side of the mounting plate. The multiple plastic grasping devices are evenly distributed around the material head grasping device with the material head grasping device as the center. The plastic grasping device includes a rotating support plate and a grasping cylinder. The center of the rear side of the rotating support plate is rotationally supported on the mounting plate through a rotating shaft and a bearing. The grasping cylinder is fixedly installed on the front side of the rotating support plate. The adjacent grasping cylinders of the four plastic grasping devices form a 90° angle. The extension line in the length direction of the grasping cylinder points to the center of the mounting plate. A slider device is provided between two adjacent plastic grasping devices in the width direction of the mounting plate. The slider device includes a sliding plate. The sliding plate is slidably connected to the mounting plate through a linear track. The linear track is arranged along the length direction of the mounting plate. The two ends of the side of the sliding plate close to the plastic grasping device are respectively connected to the rotating support plates of the corresponding two plastic grasping devices through connecting rods. The two ends of the connecting rod are respectively hinged to the sliding plate and the rotating support plate. One end of the sliding plate far from the plastic grasping device is connected with a telescopic cylinder. The telescopic cylinder is collinear with the linear track and fixedly installed on the mounting plate.

[0008] Further, within the telescopic stroke of the telescopic cylinder, the telescopic cylinder pushes the sliding plate to drive the rotating support plate to rotate by 45°.

[0009] Further, two grasping cylinders are installed on the rotating support plate. The two grasping cylinders are parallel and are arranged with a dislocation in the length direction.

[0010] Further, the material head grasping device and the plastic grasping device are pneumatic parallel jaw finger cylinders.

[0011] Further, a connecting plate is installed on the side of the sliding plate close to the telescopic cylinder. The connecting plate is fixedly connected to the sliding plate. The telescopic end of the telescopic cylinder is fixedly connected to the center of the connecting plate.

[0012] Still further, a rotating cylinder is installed between the mounting plate and the robotic arm. The rotating shaft of the rotating cylinder is connected with a rotating support seat. The rotating support seat is fixedly connected to the center of the rear side of the mounting plate.

[0013] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] The plastic body and the sprue are respectively grasped from the mold by the sprue grasping device and the plastic grasping device, and the separation and placement of the sprue and the plastic body at the corresponding storage positions are realized through the grasping and releasing of the corresponding cylinders. The telescopic cylinder cooperates with the slider device to rotate each grasped plastic body to a parallel position, which is beneficial to the subsequent cavity separation placement; the rotation of the plastic body from the forming position in the vertical plane of the mold to the placement position in the final horizontal plane is realized through the rotation cylinder and the mechanical handle. This technical solution can realize the grasping and cavity separation placement of plastics in different cavities, facilitate the consistent production of subsequent electrical connector assembly processes, improve production efficiency, and meet the stability requirements of production quality.

Detailed Description of the Preferred Embodiments

[0018] The following further details the specific embodiments of the present utility model with reference to the accompanying drawings:

[0019] As Figure 1-2 shown, the structure of the pick-and-place manipulator for the plastic body of the electrical connector is composed of a mounting plate 1, a rotation cylinder 2, a sprue grasping device 3, four plastic grasping devices 4 and a rotating mechanism 5, and is used to grasp the multi-cavity plastic body 7 and the sprue 8 formed in the mold from the forming mold and place them at the corresponding positions.

[0020] When grasping the plastic, the mounting plate 1 is in the vertical position. A robotic arm is connected to the central position at the rear of the mounting plate 1, and the robotic arm can achieve translation in the vertical and horizontal directions so as to place the plastic body 7 and the sprue at the designated positions respectively. The rotation cylinder 2 is installed at the end of the robotic arm, and the rotating shaft of the rotation cylinder 2 is connected to a rotating support seat 6, and the rotating support seat 6 is fixedly connected to the center at the rear of the mounting plate 1. The rotation cylinder 2 can achieve a 90° rotation, rotating the mounting plate 1 from the vertical state to the horizontal state, so as to rotate the plastic body 7 and the sprue 8 in the vertical state in the mold to the horizontal position, which is beneficial to the subsequent stacking work.

[0021] The sprue grasping device 3 and four plastic grasping devices 4 are installed on the front side of the mounting plate 1. The sprue grasping device 3 is located at the central position on the front side of the mounting plate 1, corresponding to the position of the sprue in the mold, and is used to grasp the sprue 8. The sprue grasping device 3 is a pneumatic parallel jaw finger cylinder.

[0022] The plastic grasping devices 4 are evenly distributed around the sprue grasping device 3 with the sprue grasping device 3 as the center. The mold in this embodiment is an 8-cavity forming mold, with every two cavities as a group. In order to save the consumption of the sprue and the forming quality, the four groups of cavities are distributed at an interval of 90°, and each group of cavities forms an angle of 45° with the vertical line and the horizontal line respectively. The four plastic grasping devices 4 correspond to the four groups of cavities respectively.

[0023] The plastic grasping device 4 consists of a rotating support plate 41 and a set of grasping cylinders 42. The grasping cylinders 42 are pneumatic parallel jaw finger cylinders. The center of the rear side of the rotating support plate 41 is rotationally supported on the mounting plate 1 through a rotating shaft 43 and bearings. Two grasping cylinders 42 are fixedly installed on the front side of the rotating support plate 41. The two grasping cylinders 42 are parallel and are arranged with a dislocation in the length direction. The two grasping cylinders 42 correspond to the two cavities in the same group.

[0024] After the plastic grasping device grasps the plastic body 7, the 8 plastic bodies 7 are coplanar but have an included angle, making it difficult to stack. Therefore, a rotating mechanism 5 is installed on the mounting plate. A rotating mechanism 5 is arranged between two adjacent plastic grasping devices 4 in the width direction of the mounting plate 1. The rotating mechanism 5 consists of a slider device and a telescopic cylinder 51. The slider device includes a sliding plate 52 and a linear track 53. The linear track 53 is fixedly installed on the mounting plate 1 and is located on the symmetry line of the two plastic grasping devices. The sliding plate 52 slides freely on the linear track. The two ends of the side of the sliding plate 52 close to the plastic grasping device are respectively connected to the rotating support plates 41 of the corresponding two plastic grasping devices 4 through connecting rods 54. The two ends of the connecting rod 54 are respectively hinged to the sliding plate 52 and the rotating support plate 41. When the sliding plate 52 slides, the rotating support plates 41 of the two plastic grasping devices 4 are driven to rotate through the two connecting rods 54, so as to adjust the angle of the grasped plastic body 7.

[0025] One end of the sliding plate 52 far from the plastic grasping device is connected to the telescopic cylinder 51. The telescopic cylinder 51 is collinear with the linear track 53 and is fixedly installed on the mounting plate 1. A connecting plate 55 is installed on the side of the sliding plate 52 close to the telescopic cylinder 51. The connecting plate 55 is fixedly connected to the sliding plate 52. The telescopic end of the telescopic cylinder 51 is fixedly connected to the center of the connecting plate 55. Within the telescopic stroke of the telescopic cylinder 51, the telescopic cylinder 51 pushes the sliding plate 52 to drive the rotating support plate 41 to rotate by 45°. After the telescopic cylinder 51 retracts, each rotating support plate 41 rotates by 45°, making the 8 plastic bodies 7 parallel.

[0026] The rotating cylinder 2 rotates 90 degrees, driving the mounting plate 1 to rotate to the horizontal position, and then drives the mounting plate 1 to translate horizontally and vertically through the robotic arm. When moving to the position of the scrap collecting bucket, the cylinder of the scrap grasping device 3 releases, and the scrap 8 falls into the barrel. When moving to the position of the plastic body 7 collecting tray, the 8 grasping cylinders 42 of the plastic grasping device 4 are sequentially released at 8 corresponding positions, and the plastics in 8 cavities are sequentially placed into the corresponding collecting trays. After the placement is completed, the rotating cylinder 2 and the robotic arm reset to the mold to enter the next cycle. The states and positions of each grasping cylinder 42, rotating cylinder 2, robotic arm, etc. are all controlled by the PLC.
