Detailed Description

In order to explain technical contents and structural features of the present invention in detail, the following description is made with reference to the embodiments and the accompanying drawings.

Referring to fig. 1 to 2 and fig. 4 to 7, the connecting wire sucking and ejecting mechanism 100 of the present invention includes a mechanism frame 10, an ejecting slider 20 slidably disposed on the mechanism frame 10 along a height direction of the mechanism frame 10, and a switching driver 30 assembled on the mechanism frame 10 and driving the ejecting slider 20 to slidably switch between a first position (shown in fig. 4 and 6) and a second position (shown in fig. 5 and 7). The mechanism frame body 10 is provided with eight wire embedding positioning grooves 11 aligned with the ejection sliding blocks 20 along the height direction of the mechanism frame body 10 and an airflow channel 12 communicated with the wire embedding positioning grooves 11, all the wire embedding positioning grooves 11 are positioned at the lower end part of the mechanism frame body 10 in a penetrating manner, so that the wire embedding positioning grooves 11 at the lower end part of the mechanism frame body 10 can absorb the connecting wires 200 from the lower part, all the wire embedding positioning grooves 11 also extend along the width direction of the mechanism frame body 10 to match the length of one section of the connecting wire 200, each wire embedding positioning groove 11 can better restrain and position each section of the connecting wire 200, and the length of the connecting wire 200 positioned outside the wire embedding positioning grooves 11 is reduced as much as possible; all the wire embedding positioning grooves 11 are also arranged in a mutually spaced manner along the length direction of the mechanism frame body 10 so as to ensure that all the sucked connecting wires 200 are regularly discharged in a mutually spaced manner; the ejector slider 20 cuts off the air flow channel 12 and ejects the connecting wire 200 with the wire inserted into the positioning groove 11 in the process of switching from the first position to the second position, as shown in fig. 5. More specifically, the following:

as shown in fig. 1 to 5 and 8, the lower end portion of the mechanism frame 10 has a downwardly protruding boss structure 13, and the wire embedding positioning groove 11 is formed on the boss structure 13 so as to downwardly bias the wire embedding positioning groove 11 with respect to the lower end portion of the mechanism frame 10 by means of the boss structure 13, which can reduce the processing area of the wire embedding positioning groove 11 at the lower end portion of the mechanism frame 10, thereby facilitating the processing and manufacturing of the wire embedding positioning groove 11. Specifically, although the number of the wire-embedding positioning grooves 11 shown in the drawings is eight, two, four, six or ten according to actual needs, that is, the number of the wire-embedding positioning grooves 11 is even, when the number of the wire-embedding positioning grooves 11 is even, every two wire-embedding positioning grooves 11 correspond to one air flow channel 12 and one ejector slider 20, and one ejector slider 20 is responsible for ejecting the connecting wire 200 at the two wire-embedding positioning grooves 11 and switching on and off one air flow channel 12. More specifically, in fig. 6 and 7, the air flow channel 12 includes a first air flow channel 121 communicatively located right above the wire insertion positioning slot 11 and a second air flow channel 122 communicatively connected to the first air flow channel 121 along the width direction of the mechanism frame 10, so as to communicate with the first air flow channel 121 along the width direction of the mechanism frame 10 by means of the second air flow channel 122, thereby facilitating the assembly and connection operation between the air flow channel 12 and the external vacuum device, and further making the arrangement of the plurality of air flow channels 12 on the mechanism frame 10 more reasonable, of course, according to actual needs, the second air flow channel 122 may also communicate with the first air flow channel 121 along the length direction of the mechanism frame 10, so the above description is not limited; and the connection between the first air flow channel 121 and the second air flow channel 122 is cut off during the process of switching the ejector slide 20 from the first position shown in fig. 4 and 6 to the second position shown in fig. 5 and 7, so that the ejector slide 20 integrates the ejection function and the switching function, on one hand, the waste of air source is effectively prevented, and on the other hand, the connection line 200 for embedding the wire into the positioning slot 11 can be reliably ejected to the corresponding position of the carrier. It should be noted that, in fig. 6 and 7, since the ejecting slider 20 cuts off the communication between the first air flow channel 121 and the second air flow channel 122 through the side wall 23, in the process of switching the ejecting slider 20 from the first position to the second position, after the ejecting slider 20 first cuts off the communication between the first air flow channel 121 and the second air flow channel 122, the connecting wire 200 with the wire inserted into the positioning groove 11 and without vacuum absorption is ejected, on one hand, the smoothness of ejecting the connecting wire 200 can be further ensured, and on the other hand, the bending deformation of the ejected connecting wire 200 is effectively prevented; of course, according to actual requirements, the ejecting operation of the ejecting slider 20 on the connecting line 220 and the cutting operation of the ejecting slider 20 to cut off the communication between the first air flow channel 121 and the second air flow channel 122 may be performed simultaneously.

As shown in fig. 2, 4 and 5, in order to make the switching driver 30 reliably control all the ejector sliders 20 to operate in coordination, the connecting wire sucking and ejecting mechanism 100 of the present invention further includes a cam shaft 40 for controlling the ejector sliders 20 to slide, the cam shaft 40 is rotatably mounted on the mechanism frame body 10, and the mechanism frame body 10 provides a supporting function and a fixed mounting place for the cam shaft 40; the axial direction of the cam shaft 40 is arranged along the length direction of the mechanism frame body 10, so that the arrangement of the cam shaft 40 on the mechanism frame body 10 is more reasonable; the cam shaft 40 is positioned directly above the ejection sliders 20 in a contact manner, so that the cam shaft 40 is always in contact with each ejection slider 20 at the same time; the switching driver 30 drives the cam shaft 40 to rotate, and the rotating cam shaft 40 drives the ejector sliders 20 to switch between the first position shown in fig. 4 and the second position shown in fig. 5, specifically, drives each ejector slider 20 to sequentially switch between the first position and the second position for sliding movement, for example, in fig. 5, the cam shaft 40 drives the leftmost ejector slider 20 to switch between the first position and the second position for sliding movement, and then drives the left-most adjacent ejector slider 20 to switch between the first position and the second position for sliding movement, and so on; to simplify the structure of the switching drive 30 for linking all the ejector sliders 20 to slide by means of the camshaft 40. Specifically, in fig. 4 and 5, the connecting line sucking and ejecting mechanism 100 of the present invention further includes a limiting rod 50 assembled and connected with the mechanism frame body 10, the limiting rod 50 passes through all the ejecting sliders 20 along the length direction of the mechanism frame body 10, each ejecting slider 20 is provided with an avoiding space 21 for the limiting rod 50 to pass through, a return elastic member 60 is arranged between each ejecting slider 20 and the limiting rod 50, and the return elastic member 60 constantly has a tendency of driving the ejecting slider 20 to slide toward the first position; so that the ejecting slider 20 is more reliably kept in contact with the cam shaft 40 by the return elastic member 60, and further, due to the action of the stopper rod 50, when the return elastic member 60 switches the ejecting slider 20 to the first position, the stopper rod 50 blocks the ejecting slider 20 to prevent the ejecting slider 20 from being excessively returned. For example, the return elastic element 60 is a compression spring, and certainly, an extension spring is selected according to actual needs, but not limited thereto; meanwhile, in fig. 2, two ends of the limiting rod 50 are fixedly connected with the mechanism frame body 10 respectively; in addition, the switching driver 30 is a motor, and the motor drives the camshaft 40 to rotate through belt transmission, of course, the camshaft 40 may also be driven to rotate through gear transmission or chain transmission, or the motor directly drives the camshaft 40 to rotate, that is, the output end of the motor is connected to the camshaft 40, and therefore the above description is not limited. In order to make the cam shaft 40 move smoothly and move all the ejector sliders 20, an ejector roller 22 for contacting the cam shaft 40 is installed at the upper end of each ejector slider 20, so that the cam shaft 40 contacts the ejector slider 20 through the ejector roller 22, but the invention is not limited thereto.

As shown in fig. 3, in order to make the contact between the mechanism frame 10 and the carrier flexible in transferring the connecting wire 200 to the carrier, the connecting wire sucking and ejecting mechanism 100 of the present invention further includes a first sliding bracket 70 and a buffering elastic member 80. The upper end portion of the mechanism frame body 10 is slidably disposed on the first sliding support 70 along the height direction of the mechanism frame body 10, so that the mechanism frame body 10 can slide relative to the first sliding support 70 along the height direction thereof, and the upper end portion of the mechanism frame body 10 is further provided with an avoidance space 14, preferably, in fig. 3, the avoidance space 14 is square, but not limited thereto; the first sliding bracket 70 protrudes out of the limit bump 71 located in the avoiding space 14, and preferably, in fig. 3, the limit bump 71 is square, but not limited thereto; the buffering elastic part 80 is positioned in the avoiding space 14, the buffering elastic part 80 is further arranged between the limiting bump 71 and the mechanism frame body 10, and the buffering elastic part 80 constantly has a tendency of driving the mechanism frame body 10 and the first sliding support 70 to slide towards a direction away from each other; the mechanism frame 10 is normally away from the first sliding support 70 downward by the buffering elastic member 80, so that when the mechanism frame 10 contacts with the carrier downward, the carrier first pushes the mechanism frame 10 upward to slide against the elastic force of the buffering elastic member 80 until the mechanism frame 10 slides to a position abutting against the first sliding support 70, thereby providing a buffering function between the mechanism frame 10 and the carrier. For example, in fig. 3, the elastic buffer member 80 is a compression spring, but is a tension spring according to actual needs, and therefore is not limited to the illustration in fig. 3.

As shown in fig. 1 to 3, in order to make the connecting wire sucking and ejecting mechanism 100 of the present invention have a fine adjustment function in the length direction and the width direction of the mechanism frame body 10, the connecting wire sucking and ejecting mechanism 100 of the present invention further includes a second sliding support 91, a manipulator mounting base 92, a first inserting and extracting device 93, and a second inserting and extracting device 94. The second sliding support 91 is slidably arranged at the lower end part of the manipulator mounting seat 92 along the length direction of the mechanism frame body 10, and the first sliding support 70 is slidably arranged at the lower end part of the second sliding support 91 along the width direction of the mechanism frame body 10, so that the manipulator mounting seat 92, the second sliding support 91 and the first sliding support 80 are sequentially assembled in an overlapping manner; the first sliding support 70 is further provided with a first slot 71 and a second slot 72, preferably, in fig. 1 and fig. 2, the first slot 71 and the second slot 72 are diagonally arranged on the first sliding support 70, so that the arrangement ensures the reliability of lock allocation on one hand, and reduces the number of the first slot 71 and the second slot 72 at the first sliding support 70 on the other hand, but not limited thereto; the first plugging device 93 and the second plugging device 94 are respectively assembled on the manipulator mounting seat 92, the first plugging device 93 is aligned with the first slot 71 along the height direction of the mechanism frame body 10, and the second plugging device 94 is aligned with the second slot 72 along the height direction of the mechanism frame body 10, so that when the first plugging device 93 is inserted into the first slot 71 and the second plugging device 94 is inserted into the second slot 72, the manipulator mounting seat 92, the second sliding support 91 and the first sliding support 70 are fixed relatively to each other and are in a static state. Specifically, in fig. 1 and fig. 2, the first plugging device 93 is in clearance fit with the first slot 71, and the second plugging device 94 is in interference fit with the second slot 72, so that during adjustment, the first plugging device 93 is inserted into the first slot 71, and after the first sliding support 70 is finely adjusted to a proper position relative to the manipulator mounting base 92, the second plugging device 94 is inserted into the second slot 72, so that fine adjustment is more reliable. For example, in fig. 1 and fig. 2, the first plugging device 93 mainly comprises a cylinder and a plug, and the second plugging device 93 is a telescopic structure, but not limited thereto. Among them, in order to make the structure of the connecting wire sucking and ejecting mechanism 100 of the present invention more compact, in fig. 1 and 2, the position 74 at which the first sliding bracket 70 is slidably coupled to the upper end portion of the mechanism frame 10 is located between the upper end portion of the mechanism frame 10 and the switching driver 30 in the width direction of the mechanism frame 10.

Compared with the prior art, the mechanism frame body 10 is provided with a plurality of wire embedding positioning grooves 11 aligned with the ejection sliding blocks 20 along the height direction of the mechanism frame body 10 and air flow channels 12 communicated with the wire embedding positioning grooves 11, all the wire embedding positioning grooves 11 are positioned at the lower end part of the mechanism frame body 10 in a penetrating manner and extend along the width direction of the mechanism frame body 10, all the wire embedding positioning grooves 11 are also arranged at intervals along the length direction of the mechanism frame body 10, and the ejection sliding blocks 20 cut off the air flow channels 12 and eject the connecting wires 200 in the wire embedding positioning grooves 11 in the process of switching from the first position to the second position; therefore, when the switching driver 30 links the ejecting slider 20 to switch to the first position, the vacuum adsorption effect is formed at the wire embedding positioning groove 11 through the air flow channel 12, so that the connecting wire 200 of one segment is correspondingly sucked into the wire embedding positioning groove 11 and is positioned and restrained by the wire embedding positioning groove 11; when the switching driver 30 links the ejecting slider 20 to switch to the second position, the ejecting slider 20 cuts off the airflow channel 12, so that the wire cannot be inserted into the positioning groove 11 to form a vacuum absorption effect, and meanwhile, the ejecting slider 20 ejects the connecting wire 200 inserted into the positioning groove 11, thereby reducing air source waste and ensuring smooth reliability of ejection of the connecting wire 200, and thus ensuring accurate reliability of transfer of the connecting wire 200.

It should be noted that the direction indicated by the arrow a in the drawing is the direction from the top to the bottom of the mechanism frame 10, the direction indicated by the arrow B in the drawing is the direction from the front to the back of the mechanism frame 10, and the direction indicated by the arrow C in the drawing is the direction from the left to the right of the mechanism frame 10, therefore, the height direction of the mechanism frame 10 described above is the direction indicated by the arrow a and the opposite direction, the width direction of the mechanism frame 10 is the direction indicated by the arrow B and the opposite direction, and the length direction of the mechanism frame 10 is the direction indicated by the arrow C and the opposite direction.
