Description

Technical Field

[0001] The invention relates to the field of busbar processing, and in particular to a turning and feeding mechanism of a full-automatic numerically controlled busbar bending machine. Background Art

[0002] The busbar refers to a common passage to which multiple devices are connected in the form of parallel branches. During the production and processing of the busbar workpiece, in order to achieve the conductive connection of the busbar, ensure the connection is stable or avoid other structures in the cabinet, the busbar needs to be twisted and bent at a certain angle. In the prior art, a busbar bending machine is usually used to bend the busbar. The busbar bending machine is usually connected after the punching and shearing machine. After the punching and shearing is completed, the busbar is placed horizontally and transported to the bending machine. Therefore, before bending the busbar, the busbar needs to be flipped to cooperate with the bending action of the bending machine. When the busbar bending machine in the prior art is working, the operator needs to perform the process of unloading - bending - taking the material (and storing) - unloading again. The labor intensity of the staff is high, the operation process is cumbersome, and the efficiency of the bending process is low. Summary of the invention

[0003] The present invention can not only realize the flipping of the busbar, but also realize the automatic delivery of the busbar to the bending mechanism through the mutual cooperation of the two flipping units, so that the whole process of flipping, feeding and bending in the busbar bending machine is automated, which greatly improves the working efficiency of the busbar bending machine and solves the above-mentioned technical problems.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A turning and feeding mechanism of a fully automatic CNC busbar bending machine includes a rotating unit, a positioning unit, a turning unit composed of the rotating unit and the positioning unit, and a feeding unit. The turning unit includes a turning table, a support seat, and a driving member. The turning table is provided with a guide portion, which is arranged along an arc direction. The support seat is provided with a first limiting member and a second limiting member. The first limiting member and the upper surface of the guide portion abut against each other, and the second limiting member and the lower surface of the guide portion abut against each other to form a limiting channel that cooperates with the guide portion. The driving member causes the guide portion of the turning table to rotate relative to the limiting channel along the arc direction of the guide portion.

[0006] The positioning unit includes two clamping members, which are respectively arranged at two table positions, wherein the clamping member arranged on any table can cooperate with the other table to clamp or release the busbar;

[0007] The rotating unit and the positioning unit constitute a turning unit. At least two turning units are provided along the busbar conveying direction. The turning table is provided with two mutually adjacent table surfaces. The turning table is arranged along the busbar conveying direction, and the turning tables of the two turning units are arranged to overlap along the busbar conveying direction.

[0008] The feeding unit includes a guide and a moving part. The guide is connected to the support seats of the two flip units. The guide is arranged along the conveying direction of the busbar. The moving part is connected to the support seat of one of the flip units. The moving part can make the support seat move back and forth along the direction of the guide.

[0009] The present invention can not only realize the flipping of the busbar, but also realize the automatic delivery of the busbar to the bending mechanism through the mutual cooperation of the two flipping units, so that the whole process of flipping, feeding and bending in the busbar bending machine is automated, which greatly improves the working efficiency of the busbar bending machine.

[0010] In a preferred implementation, the turning table includes a receiving portion and a guiding portion, the receiving portion is provided with two adjacent table surfaces, the two table surfaces are respectively used to abut the adjacent end surfaces of the busbar, so as to cooperate with the positioning unit to keep the busbar and the receiving portion in a fixed relative position during rotation.

[0011] Two adjacent tables are provided in the receiving portion, and the two tables cooperate with the positioning unit to fix the position of the busbar during the flipping process, so that the busbar can be rested on the two tables when fixed, and is not easy to fall during the flipping process, so that it is positioned more securely.

[0012] In a preferred implementation, at least one first limiting member and at least one second limiting member are provided respectively, and the limiting channel formed by the plurality of first limiting members and second limiting members is arranged along the arc direction of the guide portion.

[0013] The limiting piece arranged along the arc direction of the guide part constitutes a channel for the guide part to pass through. The first limiting piece and the upper surface of the guide part abut against each other, and the second limiting piece and the lower surface of the guide part abut against each other, so that the limiting channel is more adapted to the movement of the guide part. When the guide part moves, the second limiting piece abutting against its lower surface can provide support for it, and the first limiting piece abutting against its upper surface mainly plays a guiding role. Such a structure helps the flipping table to better realize the flipping action.

[0014] In a preferred implementation, the driving member includes a gear portion, a rack and a rack push-pull member. The gear portions are respectively connected to two adjacent table surfaces and are arranged perpendicular to each other. The rack is connected to the rack push-pull member and meshes with the gear portion. The curvature of the gear portion is consistent with the arc direction of the guide portion. The rack push-pull member can push the rack to rotate the gear portion to drive the flip table to rotate.

[0015] The driving principle of the turning table during rotation in the present invention is that a gear part is arranged on two adjacent table surfaces in the turning table, a rack is arranged on the rack push-pull member, the gear part and the rack are meshed with each other, the rack push-pull member pushes and pulls back and forth to drive the rack to move, and the rack drives the gear part to rotate. The cooperation between the gear part and the rack can not only enable the turning table to be turned over, but also control the turning angle of the turning table by controlling the push-pull distance of the rack, thereby controlling the turning angle of the busbar to meet different production needs.

[0016] In a preferred implementation, the angle between the two table surfaces of the turning table is set to 90°, and the arc direction of the guide portion and the arc of the gear portion are both set to the circumferential direction.

[0017] The angle between the two table tops is set to 90°, and the arcs of the guide part and the gear part are set in the circumferential direction, so that the busbar can reach a flip angle of 90° or within 90° on the flip table. This structure is highly flexible and can better meet production needs.

[0018] In a preferred implementation, the first position-limiting member and the second position-limiting member are configured as rollers or round roller structures, and the first position-limiting member and the second position-limiting member are respectively hinged to the support seat.

[0019] The first limit member and the second limit member are configured as rollers or round roller structures, which together constitute a limit channel for the guide part to slide between them. The design of the rollers or round rollers enables the surfaces of the guide part and the first and second limit members that contact each other to form a rolling fit, and uses rolling friction instead of sliding friction, which greatly reduces the friction between the first and second limit members and the guide part, making the flipping action of the flip table more labor-saving and smooth.

[0020] In a preferred implementation, one first limiting member is provided, and two second limiting members are provided, and the two second limiting members are symmetrically arranged relative to the first limiting member.

[0021] One first limit member is provided, and it abuts against the upper surface of the guide part, mainly playing a guiding role for the guide part. Two second limit members are provided, and they abut against the lower surface of the guide part, not only playing a guiding role, but also providing a supporting force for the guide part. Two second limit members are provided, so that the support for the guide part is more stable, making the operation state of the entire flip table more stable.

[0022] In a preferred implementation, the clamping member includes a clamping portion and a clamping push-pull member, the clamping portion is connected to the clamping push-pull member, and the clamping push-pull member can enable the clamping portion and the table surface opposite thereto to form a clamping or releasing action.

[0023] The clamping part and the table surface opposite thereto jointly form a clamping or releasing action. When the busbar is placed on the table surface, the busbar is clamped by the clamping part and the table surface in multiple directions, so that the busbar is fixed more firmly and reliably, and it is not easy to fall off during the flipping process.

[0024] In a preferred implementation, the moving part includes a screw, a slider and a power part. The screw is connected to the power part, and the power part can make the screw reciprocate along the material conveying direction. The slider is respectively connected to the screw and the support seat of one of the flipping units, and can make the support seat reciprocate along the material conveying direction.

[0025] After the busbar is placed on the turning table, it is clamped and fixed by the clamping parts, then turned over and bent; after a section of busbar is bent, the next section of busbar needs to be transported to the bending position. At this time, the busbar is first released, and the turning unit connected to the lead screw through the slider starts to move, and then clamps the busbar and transports it to the bending position when it reaches the set position, and then all the turning units clamp the busbar again to cooperate with the bending action. Through such a structure, the automatic turning, transportation and bending of the busbar can be realized, which greatly improves the production efficiency.

[0026] In a preferred implementation, the guide member is configured as two guide rails parallel to each other, and the support seat is provided with a slide groove that slidably cooperates with the guide rails.

[0027] The guide rail is arranged along the conveying direction of the busbar, and the support seat slides with the guide rail, which makes the sliding process of the support seat smoother and more stable, and can move along a pre-set route, which is conducive to the efficient conveying of the busbar and can improve the working efficiency of the bending machine.

[0028] The beneficial effects of the present invention using the above structure are:

[0029] The present invention can not only realize the flipping of the busbar, but also realize the automatic delivery of the busbar to the bending mechanism through the mutual cooperation of the two flipping units, so that the whole process of flipping, feeding and bending in the busbar bending machine is automated, which greatly improves the working efficiency of the busbar bending machine.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0044] As shown in Figures 1-4, a flipping and feeding mechanism of a fully automatic CNC busbar bending machine includes a rotating unit, a positioning unit, and a feeding unit, wherein the rotating unit and the positioning unit constitute a flipping unit. The rotating unit includes a flipping table 1, a support seat 2, and a driving member 3. The flipping table 1 is provided with a guide portion 101, and the guide portion 101 is arranged along the arc direction. The support seat 2 is provided with a first limiting member 201 and a second limiting member 202. The first limiting member 201 and the upper surface of the guide portion 101 abut against each other, and the second limiting member 202 and the lower surface of the guide portion 101 abut against each other, forming a limiting channel that cooperates with the guide portion 101. The driving member 3 causes the guide portion 101 of the flipping table 1 to rotate relative to the limiting channel along the arc direction of the guide portion 101.

[0045] The positioning unit includes two clamping members 4, which are respectively arranged at the positions of two table surfaces 1021, wherein the clamping member 4 arranged on any table surface 1021 can cooperate with the other table surface 1021 to clamp or release the busbar;

[0046] The rotating unit and the positioning unit constitute a turning unit. At least two turning units are provided along the busbar conveying direction. The turning table 1 is provided with two mutually adjacent table surfaces 1021. The turning table 1 is provided along the busbar conveying direction, and the turning tables 1 of the two turning units are provided to overlap along the busbar conveying direction.

[0047] The feeding unit includes a guide member 6 and a moving member 5. The guide member 6 is connected to the support seats 2 of the two flipping units. The guide member 6 is arranged along the conveying direction of the busbar. The moving member 5 is connected to the support seat 2 of one of the flipping units. The moving member 5 can make the support seat 2 move back and forth along the direction of the guide member 6.

[0048] The present invention can not only realize the flipping of the busbar, but also realize the automatic delivery of the busbar to the bending mechanism through the mutual cooperation of the two flipping units, so that the whole process of flipping, feeding and bending in the busbar bending machine is automated, which greatly improves the working efficiency of the busbar bending machine.

[0049] As shown in FIG. 2 , the turning table 1 includes a receiving portion 102 and a guiding portion 101. The receiving portion 102 is provided with two adjacent table surfaces 1021. The two table surfaces 1021 are respectively used to abut the adjacent end surfaces of the busbar to cooperate with the positioning unit so that the busbar and the receiving portion 102 maintain a fixed relative position during the rotation process.

[0050] Two adjacent tables 1021 are provided in the receiving portion 102, and the two tables 1021 cooperate with the positioning unit to fix the position of the busbar during the flipping process, so that the busbar can be rested on the two tables 1021 when fixed, and is not easy to fall off during the flipping process, so that it is positioned more securely.

[0051] like Figure 2 , Figure 3 As shown, at least one first limiting member 201 and at least one second limiting member 202 are provided respectively, and the limiting channel formed by the plurality of first limiting members 201 and second limiting members 202 is arranged along the arc direction of the guide portion 101 .

[0052] The limiting piece arranged along the arc direction of the guide part 101 constitutes a channel for the guide part 101 to pass through. The first limiting piece 201 and the upper surface of the guide part 101 abut against each other, and the second limiting piece 202 and the lower surface of the guide part 101 abut against each other, so that the limiting channel is more adapted to the movement of the guide part 101. When the guide part 101 moves, the second limiting piece 202 abutting against its lower surface can provide support for it, and the first limiting piece 201 abutting against its upper surface mainly plays a guiding role. Such a structure helps the flip table 1 to better realize the flipping action.

[0053] like Figure 2 , Figure 4As shown, the driving member 3 includes a gear portion 301, a rack 302 and a rack push-pull member 303. The gear portions 301 are respectively connected to two adjacent table surfaces 1021 and are arranged perpendicular to each other. The rack 302 is connected to the rack push-pull member 303 and meshes with the gear portion 301. The curvature of the gear portion 301 is consistent with the arc direction of the guide portion 101. The rack push-pull member 303 can push the rack 302 to rotate the gear portion 301 to drive the flip table 1 to rotate.

[0054] The driving principle of the turning table 1 in the present invention is that a gear part 301 is set on two adjacent table surfaces 1021 in the turning table 1, and a rack 302 is set on the rack push-pull member 303. The gear part 301 and the rack 302 are meshed with each other, and the rack push-pull member 303 pushes and pulls back and forth to drive the rack 302 to move, and the rack 302 drives the gear part 301 to rotate. The cooperation between the gear part 301 and the rack 302 can not only enable the turning table 1 to be turned, but also control the turning angle of the turning table 1 by controlling the push-pull distance of the rack 302, thereby controlling the turning angle of the busbar to meet different production needs.

[0055] like Figure 2 , Figure 4 As shown, the angle between the two table surfaces 1021 of the turning table 1 is set to 90°, and the arc direction of the guide portion 101 and the arc of the gear portion 301 are both set to the circumferential direction.

[0056] The angle between the two table surfaces 1021 is set to 90°, and the arcs of the guide part 101 and the gear part 301 are set in the circumferential direction, so that the busbar can reach a flip angle of 90° or within 90° on the flip table 1. Such a structure is highly flexible and can better meet production needs.

[0057] like Figure 3 As shown, the first limiting member 201 and the second limiting member 202 are configured as rollers or round roller structures, and the first limiting member 201 and the second limiting member 202 are hinged to the support seat 2 respectively.

[0058] The first limiting member 201 and the second limiting member 202 are configured as rollers or round roller structures, which together constitute a limiting channel for the guide portion 101 to slide therebetween. The design of the rollers or round rollers enables the surfaces of the guide portion 101 and the first limiting member 201 and the second limiting member 202 that contact each other to form a rolling fit, and uses rolling friction instead of sliding friction, thereby greatly reducing the friction between the first limiting member 201, the second limiting member 202 and the guide portion 101, making the flipping action of the flip table 1 more labor-saving and smooth.

[0059] like Figure 3As shown, there is one first limiting member 201 , and two second limiting members 202 , and the two second limiting members 202 are symmetrically arranged relative to the first limiting member 201 .

[0060] One first limit member 201 is provided, and it abuts against the upper surface of the guide portion 101, mainly playing a guiding role for the guide portion 101. Two second limit members 202 are provided, and they abut against the lower surface of the guide portion 101, not only playing a guiding role, but also providing a supporting force for the guide portion 101. Two second limit members 202 are provided, so that the support for the guide portion 101 is more stable, making the operation state of the entire turning table 1 more stable.

[0061] like Figure 2 As shown, the clamping member 4 includes a clamping portion 401 and a clamping push-pull member 402 . The clamping portion 401 is connected to the clamping push-pull member 402 . The clamping push-pull member 402 can enable the clamping portion 401 and the table 1021 opposite thereto to form a clamping or releasing action.

[0062] The clamping portion 401 and the table 1021 opposite thereto jointly form a clamping or releasing action. When the busbar is placed on the table 1021, the busbar is clamped by the clamping portion 401 and the table 1021 in multiple directions, so that the busbar is fixed more firmly and reliably, and it is not easy to fall off during the flipping process.

[0063] like Figure 1 As shown, the moving part 5 includes a screw 501, a slider 502 and a power part 503. The screw 501 is connected to the power part 503, and the power part 503 can make the screw 501 reciprocate along the material conveying direction. The slider 502 is respectively connected to the screw 501 and the support seat 2 of one of the flip units, and can make the support seat 2 reciprocate along the material conveying direction.

[0064] After the busbar is placed on the turning table 1, it is clamped and fixed by the clamping member 4, and then turned over and bent; after a section of the busbar is bent, the next section of the busbar needs to be transported to the bending position. At this time, the busbar is first released, and the turning unit connected to the lead screw 501 through the slider 502 starts to move, and then clamps the busbar and transports it to the bending position when it reaches the set position, and then all the turning units clamp the busbar again to cooperate with the bending action. Through such a structure, the automatic turning, transportation and bending of the busbar can be realized, which greatly improves the production efficiency.

[0065] like Figure 3 As shown, the guide member 6 is configured as two mutually parallel guide rails 601 , and the support seat 2 is provided with a slide groove 203 that slidably cooperates with the guide rails 601 .

[0066] The guide rail 601 is arranged along the conveying direction of the busbar, and the support seat 2 slides with the guide rail 601, so that the sliding process of the support seat 2 is smoother and more stable, and it can move along a pre-set route, which is conducive to the efficient conveying of the busbar and can improve the working efficiency of the bending machine.

[0067] The beneficial effects of the present invention using the above structure are:

[0068] The present invention can not only realize the flipping of the busbar, but also realize the automatic delivery of the busbar to the bending mechanism through the mutual cooperation of the two flipping units, so that the whole process of flipping, feeding and bending in the busbar bending machine is automated, which greatly improves the working efficiency of the busbar bending machine.

[0069] The technical solution protected by the present invention is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any one embodiment with the technical solution of one or more other embodiments is within the protection scope of the present invention. Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present invention. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
