Description

Technical Field

[0001] The present disclosure relates to the technical field of feeding devices, and in particular to a double-station alternating feeding device. Background Art

[0002] In the electronics and battery industries, existing dual-station loading mechanisms on the market typically use ball screw modules or servo linear modules to provide power, with linear guides providing guidance, driving the fixture to complete the material loading function.

DETAILED DESCRIPTION

[0038] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0039] According to one embodiment of the present disclosure, the utility model provides a double-station alternating loading device.

[0040] like Figure 1-14 As shown, a double-station alternating loading device includes:

[0041] The first fixture module 1 includes a first fixture 11, and the first fixture 11 is configured to be able to perform reciprocating linear motion along a first linear direction;

[0042] The cam lifting module 2 is provided below the first fixture module 1 and has a slide groove 22 along the first straight line direction;

[0043] The second jig module 3 includes a mounting plate 31 and a second jig 32 provided above the mounting plate 31; the mounting plate 31 is configured to be able to move linearly synchronously with the first jig 11 along a first straight line direction; the second jig 32 is movably provided on the mounting plate 31 along the vertical direction and the second jig 32 is rollingly connected to the slide 22, and the second jig 32 is configured to move up and down along the slide under the synchronous drive of the mounting plate 31, so that the second jig 32 and the first jig 11 can complete alternating loading.

[0044] The double-station alternating loading device (hereinafter referred to as "device") of the present application can realize alternating loading of the first fixture and the second fixture by setting a first fixture module, a cam lifting module and a second fixture module. For example, when the first fixture is in the loading station position, the second fixture is in the processing station position; after the first fixture and the second fixture move linearly toward each other, the first fixture moves to the processing station position, and the second fixture moves to the loading station position; thereby realizing alternating loading. The positions of the loading station and the processing station of the device of the present application are fixed, which reduces the movement stroke of the two fixtures, reduces the debugging difficulty and hardware cost investment. It also saves the space occupied by the device; in addition, since the first fixture and the second fixture move synchronously, the same drive mechanism can be used to realize power transmission, which saves costs while improving the movement accuracy of the two fixtures.

[0045] For example, when the first jig 11 is at the loading station and the second jig 32 is at the processing station, the first jig 11 and the second jig 32 first move in a synchronous linear motion toward each other. After the two jigs intersect, they each continue to move along the first linear direction until they reach the station position, that is, the first jig moves to the processing station position and the second jig moves to the loading station position. During the linear motion, the second jig 32 can move up and down along the chute 22, thereby smoothly completing alternating loading with the first jig. Therefore, the dual-station alternating loading device of the present application can reduce the movement stroke of the two jig modules, reducing the difficulty and cost of debugging.

[0046] For example, the first fixture module 1 further includes a first linear guide rail 12, which is arranged along the first linear direction, and the first fixture 11 is slidably mounted on the first linear guide rail 12. There are two first linear guide rails 12, which are respectively located on both sides of the first fixture 11 and arranged in parallel.

[0047] For example, the second fixture module 3 also includes a second linear guide 33, which is arranged along the first linear direction. The mounting plate 31 is slidably mounted on the second linear guide 33. Two second linear guides 33 are provided, one on each side of the mounting plate 31 and arranged in parallel. The present application uses the first linear guide 12 and the second linear guide 33 as guides to ensure stable movement of the first fixture 11 and the mounting plate 31.

[0048] For example, the first linear direction is the direction of reciprocating linear motion of the first fixture, the second fixture, and the mounting plate.

[0049] For example, the second fixture 32 is movably provided on the mounting plate 31 in the vertical direction. Specifically, vertical guide posts 7 are movably provided on the four corners of the mounting plate 31 so that the guide posts 7 are movably provided on the mounting plate 31 in the vertical direction. The first end of the guide post 7 is connected to the second fixture 32, and the second end is connected to the reinforcing connecting plate 8.

[0050] Furthermore, a linear bearing 9 may be provided between the mounting plate 31 and the guide post 7 . The linear bearing 9 is mounted on the four corners of the mounting plate 31 and the guide post 7 is movably mounted in the linear bearing 9 .

[0051] For example, Figure 2As shown, the double-station alternating loading device of the present application also includes a mounting frame 6, which is used to install the first linear guide 12 and the second linear guide 33. The mounting frame 6 provides installation conditions for the first linear guide 12 and the second linear guide 33. The mounting frame 6 includes a flat plate 61, a first vertical plate 62 and a second vertical plate 63; the first vertical plate 62 and the second vertical plate 63 are arranged along the first straight line direction. There are two first vertical plates 62, which are arranged parallel to each other on both sides of the flat plate 61 and perpendicular to the flat plate 61; there are two second vertical plates 63, which are located between the first vertical plates 62 and perpendicular to the flat plate 61. The first linear guide 12 is installed at the end of the first vertical plate 62, and the second linear guide 33 is installed at the end of the second vertical plate 63.

[0052] In some embodiments, as Figure 2-3 As shown, the double-station alternating loading device of the present application also includes a synchronous belt module 4, which includes a synchronous belt 41 and a synchronous pulley 42 arranged in the vertical direction. The synchronous belt 41 is wound around the synchronous pulley 42, so that the synchronous belt 41 is arranged in two layers, upper and lower. The synchronous belt 41 on the upper layer is connected to the first fixture 11, and the synchronous belt 41 on the lower layer is connected to the mounting plate 31. The synchronous pulley 42 is mounted on one of the first vertical plates 62 of the mounting frame 6.

[0053] For example, the synchronous belt 41 located on the upper layer is fixedly connected to the first fixture 11 through the first connecting plate 111 , and the synchronous belt 41 located on the lower layer is fixedly connected to the mounting plate 31 through the second connecting plate 112 .

[0054] The provision of the timing belt 41 enables the first jig 11 and the mounting plate 31 to move synchronously. Therefore, in order to ensure that the first jig 11 and the second jig 32 can move smoothly to the workstation positions after alternating loading, the first jig 11 can be connected to the timing belt 41 located on the upper layer via the first connecting plate 111 at the loading station position, and the mounting plate 31 can be connected to the timing belt 41 located on the lower layer via the second connecting plate 112 at the position corresponding to the processing station. Therefore, when the timing belt drives the first jig 11 and the mounting plate 31 to move synchronously in a straight line, the first jig 11 and the mounting plate 31 and the second jig first move synchronously toward each other until the first jig 11 and the second jig intersect. At this time, the two continue to move away from each other along the first linear guide rail and the second linear guide rail, respectively, until the first jig 11 moves to the processing station position and the second jig moves to the loading station position.

[0055] The synchronous pulleys 42 are spaced vertically apart, separating the synchronous belt 41 wound thereon into two layers, thus enabling synchronized linear motion of the first jig 11 and the mounting plate 31, connected to the upper and lower layers of synchronous belts 41. Therefore, simply by providing power to drive the first jig 11 along the first linear guide rail, thereby driving the upper layer of the synchronous belt, which in turn transmits power to the mounting plate, achieving synchronized motion of the first jig and the mounting plate. Compared to traditional dual-station loading modules, this eliminates one power mechanism, significantly reducing overall costs.

[0056] In addition, the transmission through the synchronous belt 41 is smooth, has the advantages of buffering, vibration reduction, and low noise, and has high transmission efficiency. At the same time, because the first fixture module and the second fixture module are guided by linear guide rails, the fixture moves stably, efficiently, and accurately, ensuring the accuracy of the loading station position and the processing station position, and the stability of the loading rhythm.

[0057] The device of the present application has a compact structure, uses a synchronous belt 41 to transmit power, and a linear guide rail provides high-precision guidance, which can achieve high-speed and stable operation; it reduces production costs and space occupancy.

[0058] For example, a second drive mechanism 5 can be used to provide power to the first fixture 11. Specifically, the device of the present application also includes a second drive mechanism 5 having an output end 51 capable of linear motion along a first linear direction. The output end 51 is connected to the first fixture 11 and is used to synchronously drive the first fixture 11 to reciprocate linearly along the first linear guide. For example, the second drive mechanism 5 can be a rodless cylinder mounted on the other first riser 62 of the mounting frame 6.

[0059] Alternatively, the first and second jigs can be synchronized by directly driving the synchronous belt through a first drive mechanism. Specifically, two synchronous belt modules 4 are provided, one mounted on each of the first risers 62. The first drive mechanism has a rotatable output shaft connected to one of the synchronous pulleys in the two synchronous belt modules 4. The output shaft is used to synchronously drive the synchronous pulley, thereby rotating the synchronous belt around the synchronous pulley and thus synchronized the first and second jigs.

[0060] In some embodiments, as Figure 7-8 As shown, the chute 22 has a starting position 221, a lowest point position 222 and an end position 223 along the first straight line direction; when the connection position of the second fixture 32 and the chute 22 is at the starting position 221 or the end position 223, the height of the second fixture 32 is the same as the height of the first fixture 11; when the connection position of the second fixture 32 and the chute 22 is at the lowest point position 222, the second fixture 32 is located directly below the first fixture 11 and is spaced apart.

[0061] The chute 22 formed by the starting position 221, the lowest point position 222 and the end point position 223 provides conditions for the movement of the second fixture, so that the second fixture 32 can move along the chute 22. Figure 7-8 As shown, the slide groove 22 is generally V-shaped.

[0062] For example, Figure 5-6 As shown, the cam lifting module 2 includes a cam slide plate 21, and the cam slide plate 21 is provided with a slide groove 22 along a first straight line direction;

[0063] The rolling element 23 is rollingly mounted within the chute 22 and is connected to the second fixture 32 via a connecting assembly 24. Specifically, a clearance opening 611 is defined on the flat plate 61 of the mounting frame 6. The cam chute plate 21 is positioned between the second vertical plates 63, with both ends of the cam chute plate 21 fixedly mounted on the flat plate 61, and the middle portion protruding from the clearance opening 611. The connecting assembly 24 includes a connecting vertical plate 241 and a connecting shaft 242. The first end of the connecting vertical plate 241 is connected to the second fixture 32, and the second end of the connecting vertical plate 241 is connected to the connecting shaft 242. The rolling element 23 may be a rolling bearing housed in the chute 22, with the inner ring of the rolling bearing connected to the connecting shaft 242.

[0064] When the mounting plate 31 moves linearly along the second linear guide rail 33, the second jig 32 connected thereto is driven to move linearly synchronously. Since the second jig 32 is connected to the rolling bearing through the connecting shaft 242 of the connecting assembly 24, when the second jig 32 moves linearly synchronously, the roller bearing moves in the slide groove 22 of the cam slide plate 21, that is, the roller bearing moves downward from the starting position 221 to the lowest point position 222. At this time, the second jig 32 is located directly below the first jig 11. Then the first jig 11 and the second jig 32 are staggered and continue to move linearly in opposite directions until the first jig 11 moves to the processing station position or the loading station position. At this time, the roller bearing moves to the end position 223, and the second jig moves to the loading station position or the processing station position. At this time, the second jig 32 and the first jig 11 that have completed alternating loading are at the same height to ensure the stability of the loading rhythm.

[0065] As a result, the positions of the loading and processing stations of the dual-station alternating loading device of the present application are fixed, reducing the movement stroke of the two fixture modules, reducing the difficulty and cost of debugging. When the rolling bearing of the present application is at the starting position or the end position of the chute 22, the height of the second fixture connected thereto is consistent, ensuring the accuracy of the loading and processing positions and the stability of the loading rhythm.

[0066] In addition, the positions of the two sets of fixtures can be adjusted by designing the trajectory of the chute 22 to meet the loading requirements of various products. The two sets of fixtures of the device of the present application complete the loading function of the double station by alternating up and down, which greatly reduces the space occupied by the device and is highly adaptable to occasions with high space restrictions.

[0067] The working process of the device of the present application is described in detail below with reference to the accompanying drawings:

[0068] like Figure 9-10 As shown, the first fixture 11 is located at the loading station position, and the second fixture 32 is located at the processing station position. The output end 51 of the rodless cylinder drives the first fixture 11 to move toward the processing station position. At the same time, the first fixture 11 synchronously drives the mounting plate 31 along the second linear guide rail 33 toward the loading station position through the synchronous belt 41; the mounting plate 31 then drives the second fixture 32 connected thereto to move toward the loading station position. At this time, the rolling element 23 moves downward from the starting position of the slide 22, driving the connecting vertical plate 241 and the second fixture 32 connected thereto to move vertically downward under the guidance of the guide column 7 until the rolling element 23 moves to the lowest point 222 of the slide.

[0069] like Figure 11-12 As shown, when the rolling element 23 moves to the lowest point 222 of the chute, the second fixture 32 is located directly below the first fixture 11 and the two are spaced apart; the two are staggered.

[0070] like Figure 13-14 As shown, at this time, the second driving mechanism 5 drives the first fixture 11 to continue moving toward the processing station position, and the rolling element 23 moves upward from the lowest point position 222 of the slide 22 to the end position 223. During this process, the rolling element 23 drives the second fixture 32 to move upward in the vertical direction under the guidance of the guide column 7. When it reaches the end position 223, the second fixture 32 moves to the loading station position and the first fixture 11 moves to the processing station position.
