Description

Technical Field

[0001] The utility model relates to the technical field of connector assembly, in particular to a grabbing and placing mechanism for a connector housing. Background Art

[0002] like Figure 6 As shown, a housing 100 of a connector is shown. When assembling the connector, the housing 100 needs to be placed on an assembly station. Currently, manual placement is generally adopted, but manual placement is slow and inefficient.

[0003] To this end, the inventors of the present application have begun to develop an automatic assembly device that uses the vibration of a vibration plate to transport the components and conceives a method of grabbing and placing the components on an assembly station using a robot.

[0004] However, the shell 100 conveyed by vibration needs to face forward, but in actual output, some are facing forward, some are facing backward, and there is a horizontal distance and height difference between the end of the conveyor line and the assembly station. After the robot grabs the shell 100, it cannot directly place the shell 100 on the assembly station.

[0005] In addition, in view of the current existing manipulator mechanisms, some are equipped with synchronous belt drive mechanisms to realize the multi-directional operation of the manipulator. The synchronous belt drive mechanism also includes two pulleys and a synchronous belt, so as to indirectly drive the manipulator to move through the synchronous belt. This type of manipulator mechanism, on the one hand, increases the number of parts and components due to the provision of two pulleys and a synchronous belt, and the structure is relatively complicated. On the other hand, since the manipulator is driven to move through the synchronous belt indirectly, the synchronous belt needs to be tightly fastened during the transmission connection. After being used tightly for a long time, the synchronous belt tends to become thinner at the tightening connection, resulting in loose connection and affecting the transmission quality. Moreover, the motor that drives the pulley to rotate is biasedly installed at the rear of one end of the mechanism. This makes it difficult to match and install the motor in occasions where the rear installation space is compact. Utility Model Content

[0006] In order to solve the problems of the housing orientation and the horizontal spacing and height difference between the housing and the assembly station, the utility model proposes a grabbing and placing mechanism for the connector housing, which can also effectively solve the transmission quality problem and the assembly problem in the compact installation space at the rear of the mechanism.

[0007] The control rod is a pair of arm support rods, and the support rods are connected with the support rod by the guide rail, and the control rods are connected with the guide rail by the guide rail.

[0008] In some embodiments, the front of the beam is configured to form an inner concave cavity with a side opening, the top wall of the inner concave cavity is configured to form an upper slide groove, and the bottom wall of the inner concave cavity is configured to form a lower slide groove. The beam is provided with an upper guide slide wall on the upper front wall at the opening of the inner concave cavity, and the beam is provided with a lower guide slide wall on the lower front wall at the opening of the inner concave cavity. The moving block is provided with an upper slide bar that slides with the upper slide groove and an upper flange that slides in contact with the upper guide slide wall. The moving block is also provided with a lower slide bar that slides in contact with the lower slide groove and a lower flange that slides in contact with the lower guide slide wall.

[0009] Preferably, the upper flange and the lower flange are symmetrically protruded from the top and bottom ends of the moving block, and the upper flange and the lower flange are consistent in size and shape, and are provided with a fitting sliding wall, and an arc-shaped ridge is provided on the back of the fitting sliding wall to enhance strength.

[0010] In some embodiments, a transition piece 1 and a transition piece 2 are installed and connected between the moving block and the linear cylinder. The transition piece 1 is constructed into a U-shape with a side opening. The transition piece 2 is provided with a clamping groove that passes through both sides of the transition piece 2. The upper end and the lower end of the transition piece 1 at the opening are respectively clamped on the upper top wall and the lower top wall of the clamping groove. An extended cavity is constructed between the transition piece 1 and the transition piece 2.

[0011] In some embodiments, the linear cylinder includes a cylinder body with an output end and a sliding body slidably connected to the cylinder body. The lower end of the sliding body extends a connecting body horizontally outward, and the connecting body is connected to the output end. A slide rail is provided on the front wall of the cylinder body, and a slide groove slidably matched with the slide rail is provided on the inner wall of the sliding body.

[0012] In some embodiments, the bottom of the connector is fixedly connected to a supporting seat protruding from the bottom of the connector, the cylinder body of the rotary cylinder is installed on the supporting seat, and the output end of the rotary cylinder passes through the supporting seat and is installed and connected to the robot.

[0013] Preferably, the rotary cylinder is a 180-degree rotary cylinder.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] The motor and screw assembly are configured to enable the manipulator to move horizontally. After grabbing the shell from the end of the conveyor line, the manipulator can move between the end of the conveyor line and the assembly station, thereby solving the problem of the horizontal distance between the end of the conveyor line and the assembly station.

[0016] The setting of the linear cylinder enables the manipulator to move up and down in the vertical direction, that is, to adjust the height position. In this way, after the manipulator grabs the shell at the end of the conveyor line, it can move up and down vertically toward the assembly station, thereby solving the problem of the height difference between the end of the conveyor line and the assembly station.

[0017] By setting the rotary cylinder, the manipulator can obtain a rotating motion, so that after grabbing the shell, the manipulator can drive the shell to form a horizontal rotation, so that the front of the shell faces forward;

[0018] The setting of the screw assembly avoids the problems of increased parts and complicated structure caused by the use of a synchronous belt drive mechanism. At the same time, the screw assembly includes a screw and a moving block, and the moving block is connected to the screw in a spiral manner. The connection transmission has high precision and strong stability, and will not easily become loose, thereby effectively improving the transmission quality.

[0019] By setting up the connecting frame and installing the motor at the outer end of the connecting frame, the motor can be installed at the end of the beam through the connecting frame. As a result, the beam, connecting frame and motor are basically arranged in a line to form a straight overall structure, thereby avoiding the motor being installed at the rear of the beam. Therefore, when the installation space at the rear of the beam is compact, the entire mechanism can still be matched and installed. At this time, the beam can be installed on the column near the end of the connecting frame. In this way, the moving block, linear cylinder, rotary cylinder, manipulator and other components can basically be installed in the middle of the straight overall structure, thereby maintaining the stability of the installation.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Reference Figure 1-4As shown, a gripping and placing mechanism for a connector housing includes a column 1, a crossbeam 2, a screw assembly, a motor 4, a linear cylinder 5, a rotary cylinder 6, and a manipulator 7. The screw assembly includes a screw rod 3, a moving block 8 sleeved on the screw rod 3 and spirally connected to the screw rod 3. To achieve the spiral connection, the moving block 8 is provided with an internal threaded hole that cooperates with the screw rod 3. The column 1 can be fixedly mounted on the frame (not shown) of the automatic assembly equipment, while the crossbeam 2 is fixedly mounted on the upper position of the column 1. In this embodiment, it is basically installed near the top of the column 1 and is indirectly mounted on the column 1 through a connecting plate 19. The motor 4 is mounted on the end of the crossbeam 2. The two ends of the screw rod 3 are rotatably mounted on the crossbeam 2, and one end is connected to the output end of the motor 4 to obtain rotational drive. The linear cylinder 5 is fixedly connected to the moving block 8 to obtain horizontal linear movement under the drive of the moving block 8, and the output end of the linear cylinder 5 is set vertically downward. The rotary cylinder 5 is connected to the output end of the linear cylinder 5 , and the output end of the rotary cylinder 6 is vertically downward and connected to the manipulator 7 .

[0029] It should be noted that the linear cylinder 5 refers to a cylinder that outputs linear motion, and the rotary cylinder 6 refers to a cylinder that outputs rotary motion. In this embodiment, a cylinder that outputs 180-degree rotary motion is selected to achieve a 180-degree rotation of the object.

[0030] The above components are arranged in coordination to achieve horizontal and vertical movement of the manipulator, as well as 180-degree rotation of the manipulator, so that the gripped housing 100 can be moved horizontally and vertically toward the assembly station for placement on the assembly station. If the front of the housing 100 is facing forward, it can be rotated 180 degrees so that the front of the housing 100 faces forward.

[0031] In this embodiment, the specific structure of the crossbeam 2 is achieved in the following manner: a connecting end plate 9 is provided at one end of the crossbeam 2, a connecting frame 10 is provided at the other end of the crossbeam 2, the motor 4 is mounted on the outer end of the connecting frame 10, and the output end of the motor 4 passes through the outer end and extends into the connecting frame 10, one end of the screw rod 3 is rotatably mounted on the connecting end plate 9, and the other end of the screw rod 3 is rotatably mounted on the inner end of the connecting frame 10 and also passes through the inner end into the connecting frame 10 to connect with the output end of the motor 4. Thus, under the action of the motor, the screw rod 3 is driven to rotate, and the moving block 8 is threadedly connected to the screw rod 3, so that the moving block 8 can be driven to move along the screw rod 3. When the screw rod 3 remains horizontal, it will move the moving block 8 horizontally.

[0032] In this embodiment, the front face of the crossbeam 2 is configured with a side-opening inner cavity 11, the top wall of the inner cavity 11 is configured with an upper slide groove 101, and the bottom wall of the inner cavity 11 is configured with a lower slide groove 102. The crossbeam 2 is provided with an upper guide slide wall 103 on the upper front wall at the opening of the inner cavity 11, and a lower guide slide wall 104 on the lower front wall at the opening of the inner cavity 11. Correspondingly, the movable block 8 is provided with an upper slide bar 801 that slidably cooperates with the upper slide groove 101, an upper flange 802 that slides in contact with the upper guide slide wall 103, and a lower slide bar 803 that slidably cooperates with the lower slide groove 102, and a lower flange 804 that slides in contact with the lower guide slide wall 104. After the crossbeam 2 and the moving block 8 of this structure are arranged in coordination, it can ensure that the moving block 8 remains stable during the movement without shaking. Even if the moving block 8 is indirectly connected to components such as the linear cylinder 5, the rotary cylinder 6, and the manipulator 7, it can still maintain stable movement.

[0033] In this embodiment, as a further improvement and optimization, the upper flange 802 and the lower flange 804 are symmetrically protruded from the top and bottom ends of the moving block 8, and the upper flange 802 and the lower flange 804 are of the same size and shape, both of which are adapted to fit the sliding wall 805, and an arcuate ridge 806 is provided on the back of the sliding wall 805. The provision of the arcuate ridge 806 effectively increases the strength of the flange and allows it to fit more closely to the guide sliding wall.

[0034] During actual assembly, due to the compact installation space on the equipment, the column 1 is some distance away from the assembly station and cannot be close enough to the assembly station. Therefore, in order to enable the manipulator 7 to be located above the assembly station after horizontal movement and vertical downward movement after installation and connection, a transition piece 12 and a transition piece 2 13 are installed and connected between the moving block 8 and the linear cylinder 5. The transition piece 12 is constructed into a U-shape with a side opening, and the transition piece 2 13 is provided with a clamping groove 14, which passes through both sides of the transition piece 2 13, and the upper and lower ends of the transition piece 12 at the opening are respectively clamped on the upper top wall and the lower top wall of the clamping groove 14, and an extension cavity 15 is constructed between the transition piece 12 and the transition piece 2 13. On the one hand, the extension cavity 15 can effectively reduce the weight of the transition piece 12, and on the other hand, it can increase the distance between the moving block 8 and the linear cylinder 5. It can be seen that by disposing the two transition pieces 12 and 13, the distance between the moving block 8 and the linear cylinder 5 is increased, thereby indirectly making the manipulator 7 closer to the assembly station and located above the assembly station.

[0035] To achieve the connection between the linear cylinder 5 and the rotary cylinder 6, the linear cylinder 5 includes a cylinder body 501 with an output end, and a sliding body 502 slidably connected to the cylinder body 501. A connector 503 extends horizontally outward from the lower end of the sliding body 502, which is fixedly connected to the output end of the linear cylinder 5. A slide rail 16 is provided on the front wall of the cylinder body 501, and a slide groove 17 is provided on the inner wall of the sliding body 502, which slidably cooperates with the slide rail 16. The bottom of the connector 503 is fixedly connected to a support seat 18 that protrudes from the linear cylinder 5. The cylinder body of the rotary cylinder 6 is mounted on the support seat 18, and the output end of the rotary cylinder 6 passes through the support seat 18 and is connected to the manipulator 7. Thus, through the above-mentioned structural arrangement, the rotary cylinder 6 can be connected to the linear cylinder 5 and can generate vertical up and down motion under the drive of the linear cylinder 5.

[0036] The grabbing and placing mechanism of the present invention can realize the grabbing and placing of the connector housing 100, wherein the manipulator 7 can be directly purchased from outside.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
