Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 and 2, the press-fitting production line according to an embodiment of the present invention includes a first conveying line 2, a second conveying line 3, a clamping mechanism 100, a press-fitting mechanism 10, and a welding mechanism 5. The first conveyor line 2 and the second conveyor line 3 are mounted on a base (not shown in the figure), the first conveyor line 2 having a first processing section, the second conveyor line 3 having a second processing section corresponding to the first processing section. The first conveyor line 2 is capable of conveying workpieces at a conveying speed within a first processing section having press-fit stations. The press-fitting mechanism 10 is mounted on the base and is disposed in correspondence with the press-fitting station. The pressing mechanism 10 comprises a synchronizing component 11 and a lifting component 12, wherein the synchronizing component 11 is provided with a pressing surface for pressing a workpiece, the pressing surface moves at a conveying speed when the workpiece is pressed, and the lifting component 12 is used for driving the synchronizing component 11 to move along a direction perpendicular to the conveying speed. The clamping mechanism 100 is used for clamping a workpiece, and the second conveyor line 3 is capable of conveying the clamping mechanism 100 at a conveying speed within the second processing section.
It should be noted that in this embodiment, the speed includes the magnitude and direction, i.e., the conveying speed is also a vector including the magnitude and direction.
With the above-described press-fitting line, since the press-fitting surface of the press-fitting mechanism 10 has the same moving speed as the work piece in the process of press-fitting the work piece, the press-fitting surface and the work piece remain relatively stationary in the conveying direction of the work piece. Therefore, in the press-fitting process, the first conveying line 2 can continue conveying the workpiece, and the production efficiency can be increased without stopping or removing the workpiece from the first conveying line 2. Moreover, the clamping mechanism 100 of the press-fitting production line also moves at the same speed as the workpiece, so that the clamping mechanism 100 and the workpiece remain relatively stationary in the conveying direction of the workpiece, whereby the clamping mechanism 100 can clamp the workpiece during press-fitting to position the workpiece during press-fitting.
In order to improve the automation degree of the press-fit production line, the second conveying line 3 can continuously and automatically supply the clamping mechanism 100 in the processing process, so that the workpiece on the first conveying line 2 can be clamped by the clamping mechanism 100 when entering the first processing section, and the second conveying line 3 is set to be an annular conveying line. The second conveyor line 3 has a first station 301 and a second station 302, the second processing section is located between the first station 301 and the second station 302, when the clamping mechanism 100 is located at the first station 301, the clamping mechanism 100 clamps the workpiece, when the clamping mechanism 100 is located at the second station 302, the clamping mechanism 100 is reset, and returns to the first station 301 again along with the second conveyor line 3.
In other embodiments, the second conveyor line 3 may also be a rectilinear conveyor line. At this time, after the gripper mechanism 100 on the second conveyor line 3 moves to the end of the second conveyor line 3, it is necessary to reinstall the gripper mechanism to the second conveyor line before starting the next working cycle.
In addition, in order to make the work piece stably place on first transfer chain 2, the pressure equipment production line still includes tool 4, and tool 4 installs in first transfer chain 2, and when tool 4 is located first processing section, tool 4 and fixture 100 one-to-one. Meanwhile, in order to increase the degree of automation of the press-fitting production line, the first conveyor line 2 is an annular conveyor line, similar to the structure of the second conveyor line 3. In this way, the jig 4 can be continuously provided.
The specific structure of the press-fitting mechanism 10 is further described below with reference to fig. 3 to 5:
In this embodiment, the synchronizing assembly 11 of the press-fitting mechanism 10 includes a press-fitting driving member 111 and a press-fitting member 112, the press-fitting driving member 111 is connected to the lifting assembly 12, the press-fitting member 112 includes a press-fitting wheel 1121, and the press-fitting wheel 1121 has a press-fitting surface. The press-fit driving member 111 can drive the press-fit wheel 1121 to rotate. When the press-fit wheel 1121 presses a workpiece, the surface of the press-fit wheel 1121 deforms due to the pressing to form a plane, which is parallel to the plane, and the direction perpendicular to the axis of the press-fit wheel 1121 is parallel to the direction of the conveying speed. When the press-fit wheel 1121 rotates, the speed of the press-fit surface is the same as the conveying speed.
To increase the press-fit surface area, the press-fit member 112 includes a plurality of press-fit wheels 1121 and a timing belt 1122, and the plurality of press-fit wheels 1121 are arranged in the direction of the conveying speed and are drivingly connected by the timing belt 1122. At this time, the press-fit wheel 1121 indirectly presses the workpiece through the synchronous belt 1122, and the synchronous belt 1122 can increase the contact area between the press-fit member 112 and the workpiece, so that the workpiece is more uniformly stressed. Moreover, the press-fitting wheel 1121 is used to press-fit the workpiece, the position of the press-fitting surface is kept constant all the time, the press-fitting member 112 does not displace in the conveying speed direction, and the space occupied by the press-fitting member 112 in the conveying speed direction can be reduced.
In other embodiments, the press-fitting member 112 may be a flat plate structure, and the press-fitting surface is a surface of the press-fitting member 112 facing the workpiece. The press-fitting driving member 111 can drive the press-fitting member 112 to perform a linear movement at a conveying speed and reset after the press-fitting is completed to press-fit the next work.
It will be appreciated that in this embodiment, the lifting assembly 12 comprises a cylinder having a moving end connected to the press-fit assembly capable of driving the press-fit assembly to move in a vertical direction to press-fit the workpiece. In other embodiments, the lifting assembly 12 may also be a slider-crank or other structure.
In addition, the press-fitting production line further comprises a supporting mechanism 20, wherein the supporting mechanism 20 comprises a supporting frame 21 and a supporting piece, the supporting piece is a supporting wheel 22 in the embodiment, the supporting frame 21 is arranged on the base, and the supporting wheel 22 is rotationally connected with the supporting frame 21 and is provided with a supporting surface for supporting the jig 4. When the workpiece is pressed, the jig 4 and the workpiece are pressed by the pressing member 112, and a downward movement trend is generated, and the supporting wheel 22 can support the jig 4, so that the pressing process is more stable. Meanwhile, the supporting wheels 22 are rotationally connected with the supporting frame 21, so that rolling friction is generated between the jig 4 and the supporting frame 21, and the influence on the workpiece conveying of the first conveying line 2 is small. It can be appreciated that the supporting surface may support the jig 4, and may be directly contacted with the jig 4, or may be indirectly contacted with the jig 4 through the structure of the first conveying line 2.
In other embodiments, the support may also include structure that moves linearly at the feed rate, and the support moves at the feed rate to remain relatively stationary with the workpiece in the direction of the feed rate as the workpiece is being press-fitted. The press-fitting is finished, and the supporting piece is reset to play a supporting role when the next workpiece is pressed.
In this embodiment, the workpiece includes a battery cell, an aluminum case, and a battery cover, and the aluminum case is sleeved on the battery cell and the battery cover in the press-fitting process. Because there may be friction between the aluminum housing and the battery cover to produce metal scraps, etc. during the press-fitting process, the press-fitting production line further includes a dust removing mechanism 200, the dust removing mechanism 200 is disposed on the first conveying line 2 or the press-fitting mechanism 10, and the tuyere of the dust removing mechanism 200 faces the position of the jig 4 for placing the workpiece. The dust removing mechanism 200 moves along with the first conveying line 2 and keeps relatively static with the workpiece in the conveying direction of the workpiece, so that the dust removing mechanism 200 can always play a role in dust removal in the press mounting process, and the processing quality is improved.
The specific structure of the clamping mechanism 100 is further described below with reference to fig. 6 and 7:
The clamping mechanism 100 comprises a primary positioning component 106, a first clamping component 101, a second clamping component 102 and a third clamping component 103 which are connected in sequence. The primary positioning component 106 is configured to drive the first clamping component 101 to move along a primary positioning direction. The first clamping assembly 101 includes a first driving member 1011 and at least one pair of first moving members 1012, the first driving member 1011 being connected to the primary positioning assembly 106 and being capable of driving the pair of first moving members 1012 to move in opposite directions along a first linear direction X. The second clamping assembly 102 includes a second driving member 1021 and at least one pair of second moving members 1022, wherein the second driving member 1021 is connected to the first moving member 1012 and is capable of driving the pair of second moving members 1022 to move in opposite directions along the second linear direction Y. The third clamping assembly 103 includes a third driving member 1031 and at least one pair of third moving members 1032, and the third driving member 1031 is connected to the second moving member 1022 and is capable of driving the pair of third moving members 1032 to move in opposite directions along the third linear direction Z. The first linear direction, the second linear direction and the third linear direction are perpendicular to each other, and the third linear direction is the same as the initial positioning direction.
In the first station 301, the preliminary positioning component 106 drives the first clamping component 101 to drive the second clamping component 102 and the third clamping component 103 to move along the preliminary positioning direction, so that at least part of the structure of the workpiece is located between the paired third moving components 1032. Then, the first driving member 1011, the second driving member 1021, and the third driving member 1031 are respectively operated so that the paired third moving members 1032 approach the workpiece in the first, second, and third linear directions to clamp the workpiece in at least one of the first, second, and third linear directions.
In this embodiment, the primary positioning assembly 106 includes a lifting motor to drive the first clamping assembly 101, the second clamping assembly 102 and the third clamping assembly 103 to approach the workpiece, so that the workpiece is located in a space formed by a plurality of third moving members 1032 of a plurality of third clamping assemblies 103, and primary positioning is achieved, and more precise control is achieved through the first clamping assembly 101, the second clamping assembly 102 and the third clamping assembly 103, so as to accurately clamp the workpiece. In this embodiment, the initial positioning direction is a vertical direction, that is, a third linear direction, and in other embodiments, may be the second linear direction. By providing the primary positioning assembly 106.
In this embodiment, the first clamping assembly 101, the second clamping assembly 102 and the third clamping assembly 103 are all clamping jaw cylinders, and taking the first clamping assembly 101 as an example, the first driving member 1011 is a cylinder portion of the clamping jaw cylinders, and the first moving members 1012 arranged in pairs are clamping jaws of the clamping jaw cylinders.
In this embodiment, in order to enable the third moving member 1032 to better clamp the workpiece, the third moving member 1032 has a first clamping surface and a second clamping surface, the first clamping surface is perpendicular to the third linear direction, the second clamping surface is perpendicular to the second linear direction, and the first clamping surfaces of the paired third moving members 1032 are disposed opposite to each other to clamp the workpiece in the third linear direction. The second gripping surfaces of the pair of third motions are coplanar and disposed opposite the second gripping surfaces of the third motion members 1032 of the pair of third gripping assemblies 103 to grip the workpiece in the second linear direction. In other embodiments, the third motion member 1032 may also have only the first gripping surface to grip the workpiece in only the third linear direction. Of course, the third moving member 1032 may also have a third clamping surface perpendicular to the first straight line direction, the third clamping surface being in contact with an end surface of the workpiece perpendicular to the first straight line direction, and an end surface of the other end of the workpiece perpendicular to the first straight line direction being in contact with an end surface of the third moving member 1032 of the other third clamping assembly 103 to clamp the workpiece in the first straight line direction.
It should be noted that, in this embodiment, the first moving member 1012, the second moving member 1022 and the third moving member 1032 are all arranged in pairs, and the clamping mechanism 100 can clamp the workpiece through its own structure. In other embodiments, the first moving member 1012, the second moving member 1022 and the third moving member 1032 may be separate members, and then clamped together by the jig 4 or other structures such as the first conveying line 2.
In addition, during the press-fitting process, the clamping mechanism 100 clamps the workpiece at a press-fitting speed, which is a speed at which the press-fitting mechanism 10 presses the workpiece. In this way, the clamping mechanism 100 always clamps the workpiece during the press-fitting process. Specifically, the third motion member 1032 is always in contact with the workpiece.
In addition, in this embodiment, after the press-fitting of the workpiece is completed, in order to avoid the problem of dislocation or the like of the workpiece in the subsequent transportation process, the workpiece is electrically welded after the press-fitting is completed. However, after the aluminum shell is sleeved, the welding position is positioned at the opening of the aluminum shell, namely below the workpiece, so that the welding is inconvenient. Therefore, the workpiece needs to be turned over and then welded. In this embodiment, the second driving member 1021 is rotatably coupled to the first moving member 1012. The clamping mechanism further includes a flipping assembly 104, the flipping assembly 104 being capable of driving rotation of one of the second clamping assemblies 102 in a pair. Since the paired second clamping assemblies 102 clamp the workpiece, when one second clamping assembly 102 rotates, the other second clamping assembly 102 can be driven to rotate by the third clamping assembly 103 and the workpiece so as to turn over the workpiece.
Specifically, in the present embodiment, the overturning assembly 104 includes an overturning motor and a transmission member, and the axis of the overturning motor is parallel to the first linear direction and is connected with the second driving member 1021 through the transmission member, so that the structure is simple. Further, the turnover motor has a first end connected to the transmission member and a second end opposite to the first end, and the second end is close to the workpiece relative to the first end in the first linear direction, so that the main structures of the motor are located between the pairs of first moving members 1012, so as to reduce the space occupied by the whole clamping mechanism 100 in the first linear direction.
In addition, in order to allow the second clamp assembly 102 to rotate relative to the first motion member 1012 only when the workpiece needs to be flipped, the clamp mechanism 100 further includes a brake assembly 105 to block rotation of the second clamp assembly 102 during times other than workpiece flipping. The brake assembly 105 may be a clutch structure or a pin brake structure, that is, the brake assembly 105 is fixed on the first moving member 1012, when braking is required, the pin is inserted into the pin hole of the second driving member 1021, and when braking is not required, the pin is pulled out from the pin hole. Alternatively, the brake assembly 105 may have the same structure as the flipping assembly 104, and when the workpiece is flipped, the second clamping assembly 102 is driven to rotate synchronously with the flipping assembly 104, and the brake assembly 105 is not operated for the rest of the time, so that the motor shaft of the brake assembly 105 is kept stationary to realize braking.
In summary, the following describes the working procedure of the press-fitting production of this embodiment completely:
The workpiece 1 is placed on the first conveying line 2 through the jig 4, when the first conveying line 2 conveys the workpiece to the corresponding first processing section, the second conveying line 3 conveys the clamping mechanism 100 to the first station 301 of the second processing section, and the speed of the first conveying line 2 conveying the workpiece in the first processing section is the same as the speed of the second conveying line 3 conveying the clamping mechanism 100 in the second processing section. At this time, the lifting assembly 12 of the clamping mechanism 100 drives the first clamping assembly 101, the second clamping assembly 102 and the third clamping assembly 103 to move downward, so that the workpiece is located in the clamping space of the clamping mechanism 100. Then, the method comprises the steps of. The first clamping assembly 101, the second clamping assembly 102 and the third clamping assembly 103 are operated respectively so that the plurality of third moving members 1032 clamp the workpiece and position the workpiece.
While the clamping mechanism 100 is in operation, the first conveying line 2 and the second conveying line 3 continuously work, when the clamping mechanism 100 clamps a workpiece and moves to a press-fitting station, the press-fitting driving piece 111 drives the press-fitting piece 112 to move downwards so that the synchronous belt 1122 of the press-fitting piece 112 contacts the workpiece, and simultaneously, under the driving of the press-fitting wheel 1121, the part of the synchronous belt 1122, which contacts the workpiece, moves at the same speed as the workpiece, so that the synchronous belt 1122 and the workpiece keep relatively stationary in the conveying direction of the workpiece, namely, the part of the synchronous belt 1122, which contacts the workpiece, moves downwards only relative to the workpiece, so that press-fitting is realized. In the press-fitting process, the dust removing mechanism 200 can also remove metal scraps and the like generated in the press-fitting process. After the press-fitting is completed, the press-fitting driving member 111 drives the press-fitting member 112 to return, and the workpiece and the clamping mechanism 100 continue to move in the conveying direction.
Before the clamping mechanism 100 clamps the workpiece to move to the welding station, the turnover motor is operated to turn the workpiece 180 °, and the brake assembly 105 brakes after the workpiece is turned over to complete the welding at the welding station. After the clamping mechanism 100 clamps the workpiece to the second station 302, the clamping mechanism 100 is reset to separate from the workpiece. So far, the press-fitting process has been completed, and the clamping mechanism 100 separated from the workpiece is returned to the first station 301 along the annular second conveyor line 3 to start the next working cycle. The workpiece on the first conveying line 2 continues to finish subsequent processing, leaves the first conveying line 2 after finishing processing, and returns the jig 4 separated from the workpiece to the workpiece feeding position along with the annular first conveying line 2 so as to start the next working cycle.
Therefore, in the working process, the first conveying line 2 and the second conveying line 3 are always in the working state, and the press-fitting machine is not required to stop or get off the line of the workpiece from the first conveying line 2 in the welding process, so that the machining efficiency can be effectively improved. Moreover, the clamping mechanism 100 clamps the workpiece during the whole working process, so that the workpiece is effectively positioned to improve the processing quality. While at the same time. The clamping mechanism 100 can also turn over the workpiece without turning over by other structures, so that the structure of the press-fitting production line can be simplified, and the machining efficiency can be improved.
It should be noted that, in the present embodiment, the first conveying line 2 and the second conveying line 3 are both magnetic drive production lines, and in other embodiments, the first conveying line 2 and the second conveying line 3 may be conveying lines adopting a driving belt or the like.
The foregoing disclosure is illustrative of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
