Description

Technical Field

[0001] The present invention is used in the field of battery production equipment, and particularly relates to a support switching mechanism and a support switching method. Background Art

[0002] During the production and processing of products, a loading device is generally required to place the products. The loading device needs to support and limit the products. In addition, the loading device also needs to consider the positional relationship between the parts of the product to be processed and the processing instruments to ensure that the products fixed on the loading device can be adapted to the processing instruments. However, the parts of the product to be processed are often multi-directional, and the structure of the existing loading device is fixed. Therefore, when processing different parts of the product, it is often necessary to replace different loading devices to make the parts of the product to be processed adapt to the corresponding processing instruments. In this way, it is often necessary to stop the machine to replace the loading device, thus affecting the production efficiency.

[0003] For example, during the process of processing the tabs and connecting pieces of the battery cells, the supporting components for supporting the products are generally integrally formed. When a certain part of the product needs to be processed, the supporting components often hinder other structures from processing it. At this time, it is often necessary to stop the machine and replace the fixtures, thus affecting the production efficiency. Summary of the Invention

[0009] The supporting and switching mechanism according to the embodiment of the present invention has at least the following beneficial effects: The product to be processed is supported on the supporting device and the supporting block. During the working process, the sliding transverse plate is moved, so that the transverse plate pushes the supporting block on one side of the supporting device. The supporting block is turned upwards under the pushing of the transverse plate, so that the supporting block is aligned on one side of the supporting device. At the same time, the supporting block on the other side of the supporting device will turn downwards under the supporting device due to the loss of the supporting force of the transverse plate. When it is necessary to process the product on the other side of the supporting device, the transverse plate slides in the reverse direction to push and turn up the supporting block on the other side of the supporting device. This kind of load-bearing switching mechanism can realize the switching of load-bearing on both sides of the supporting device, so it can meet the requirements of different processes without stopping the machine for type change, thus effectively improving the production efficiency, solving the problem of inconvenient existing processing, and achieving the effect of convenient processing and free switching.

Detailed Description of the Invention

[0035] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention. However, it should not be construed as a limitation on the protection scope of the present invention.

[0036] In the present invention, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of the present invention, rather than indicating or implying that the technical features referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the present invention.

[0037] In the present invention, the meaning of "several" is one or more, the meaning of "multiple" is two or more, and "greater than", "less than", "exceeding", etc. are understood not to include the base number; "above", "below", "within", etc. are understood to include the base number. In the description of the present invention, if "first" and "second" are described, they are only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0038] In the present invention, unless otherwise clearly defined, words such as "arranged", "installed", "connected", etc. should be understood in a broad sense. For example, they can be directly connected, or indirectly connected through an intermediate medium; they can be fixedly connected, or detachably connected, or integrally formed; they can be mechanically connected, or electrically connected or capable of communicating with each other; they can be the connection inside two components or the interaction relationship between two components. Those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0039] During the process of product production and processing, generally a loading device is needed to place the product. The loading device needs to support and limit the product. In addition, the loading device also needs to consider the positional relationship between the part of the product to be processed and the processing instrument, so as to ensure that the product fixed on the loading device can be adapted to the processing instrument. However, the parts of the product to be processed are often multi-directional, and the structure of the existing loading device is fixed. Therefore, when processing different parts of the product, it is often necessary to replace different loading devices to make the part of the product to be processed adapt to the processing instrument. In this way, it is often necessary to stop the machine to replace the loading device, thus affecting the production efficiency.

[0040] For example, during the process of processing the tab and connecting piece of an electric core, the supporting component for supporting the product is generally integrally formed. When a certain part of the product needs to be processed, the supporting component often hinders other structures from processing it. At this time, it is often necessary to stop the machine and replace the fixture, thus affecting the production efficiency.

[0041] See Figures 1 to 6 , the present invention provides a support switching mechanism, including a base 100, a support device, and a transverse moving plate 300. The support device is fixed on the base 100. The two ends of the support device are rotatably installed with support blocks 211. The transverse moving plate 300 is slidably installed on the base 100. The sliding direction of the transverse moving plate 300 is the same as the distribution direction of the support blocks 211 at both ends of the support device. The transverse moving plate 300 is used to push up and flip a support block 211 at one end of the support device to align with the support device and perform support.

[0042] During the working process, the product to be processed is fixed on the supporting device and the supporting block 211. Slide the transverse moving plate 300 so that the transverse moving plate 300 pushes against the supporting block 211 on one side of the supporting device. The supporting block 211 flips upward under the push of the transverse moving plate 300 and aligns on one side of the supporting device. At the same time, the supporting block 211 on the other side of the supporting device will flip downward under the supporting device because it loses the supporting force of the transverse moving plate 300. When processing a product on the other side of the supporting device, the transverse moving plate 300 slides in the reverse direction to flip up the supporting block 211 on the other side of the supporting device. This kind of load switching mechanism can realize load switching on both sides of the supporting device, so it can meet the requirements of different processes without stopping the machine for tool change, thus effectively improving production efficiency, solving the problem of inconvenient existing processing, achieving the effects of convenient processing and smooth switching. At the same time, it is not necessary to design and develop a variety of fixtures, reducing the processing cost of the fixtures.

[0043] In some embodiments, the length of the transverse moving plate 300 is less than the sum of the lengths of the supporting device and one of the supporting blocks 211. So that each time the transverse moving plate 300 transversely moves, it can only push one of the supporting blocks 211 to flip upward, while the other supporting block 211 will flip downward due to losing the supporting force of the transverse moving plate 300.

[0044] Of course, the length of the transverse moving plate 300 can also be appropriately longer than the sum of the lengths of the supporting device and one of the supporting blocks 211.

[0045] In some embodiments, the supporting device is a supporting plate, and the product is placed on the supporting plate.

[0046] In some other embodiments, the supporting device is a clamping fixture 200, and the clamping fixture 200 is used to carry the product and clamp the product. The following recorded supporting devices are all clamping fixtures 200.

[0047] Specifically, the clamping fixture 200 includes a carrying platform 210 and four clamping devices 220. The four clamping devices 220 are distributed in pairs and installed on the two long sides of the carrying platform 210. The two supporting blocks 211 are distributed in pairs and installed on the two short sides of the carrying platform 210. The supporting blocks 211 are rotationally connected to the carrying platform 210 through hinges. The carrying platform 210 and the supporting blocks 211 are used to support the product, and the four clamping devices 220 are used to clamp and fix the product.

[0048] In order to ensure the stable support of the transverse moving plate 300 for the supporting block 211, in some embodiments, transverse moving plates 300 are provided on both sides of the base 100, and the two transverse moving plates 300 transversely slide to push against the supporting block 211 and support the supporting block 211.

[0049] In some embodiments, the base 100 includes a first support 110 and a second support 120. The second support 120 is located on one side of the first support 110. The first support 110 is higher than the second support 120. The supporting device is fixed on the first support 110, and the transverse moving plate 300 is slidably mounted on the second support 120.

[0050] Specifically, the base 100 further includes a bottom plate 130. There are two first supports 110 and two second supports 120. Both the first support 110 and the second support 120 are of I-shaped structures. The two first supports 110 are fixedly arranged opposite to each other at intervals on the bottom plate 130, and the two second supports 120 are fixedly arranged opposite to each other at intervals on the bottom plate 130. The two first supports 110 are located inside the two second supports 120. The bearing table 210 of the clamping fixture 200 is fixed on the tops of the two first supports 110.

[0051] In some embodiments, a slide rail 121 is provided on the second support 120, and a slider 122 is slidably assembled on the slide rail 121. The transverse moving plate 300 is fixed on the slider 122.

[0052] Specifically, since the first support 110 is higher than the second support 120, there is a distance between the top of the second support 120 and the bottom of the bearing table 210. Slide rails 121 are installed on the tops of the two second supports 120. The extending direction of the slide rails 121 is the same as the distribution direction of the two supporting blocks 211. A slider 122 is slidably assembled on each slide rail 121, and the transverse moving plate 300 is fixed on the slider 122.

[0053] The transverse moving plate 300 is of a strip-shaped plate structure. The transverse moving plate 300 does not contact the bearing table 210, and the transverse moving plate 300 does not contact the first support 110.

[0054] In some embodiments, the support switching mechanism further includes a transverse driving device 500 for pushing the transverse moving plate 300 to slide.

[0055] Specifically, a connecting member 600 is provided between the transverse moving plate 300 and the transverse driving device 500. The connecting member 600 includes a connecting block 610 and a connecting plate 620. The connecting block 610 is fixedly connected to the connecting plate 620. The connecting plate 620 is connected to the transverse moving plate 300, and the connecting block 610 is aligned with the power output end of the transverse driving device 500.

[0056] Specifically, the transverse movement driving device 500 includes a third support 510 and two transverse movement cylinders 520. The third support 510 is provided on one side of the base 100. The two transverse movement cylinders 520 are horizontally fixed on both sides of the third support 510. A connecting plate 620 is fixedly installed on the lower side of each of the two transverse plates 300. A connecting block 610 is fixed on each connecting plate 620. The two connecting blocks 610 are aligned with the telescopic rods of the two transverse movement cylinders 520. During the working process, the telescopic rods of the transverse movement cylinders 520 push the two connecting members 600, so that the two connecting members 600 drive the two transverse plates 300 to move horizontally and slide.

[0057] See Figure 7 , Figure 8 , in order to facilitate the fixing of the supporting block 211, in some embodiments, a first buckle 700 is provided on the supporting block 211, and a second buckle 800 is provided on the supporting device. The first buckle 700 and the second buckle 800 are detachably connected.

[0058] Specifically, the first buckle 700 is installed in the middle of the bottom of the supporting block 211, and the second buckle 800 is installed at the position corresponding to the first buckle 700 on the bottom of the bearing platform 210.

[0059] During the working process, when the transverse plate 300 pushes and flips the supporting block 211 on one side of the supporting device to align with the bearing platform 210, the supporting block 211 on the other side of the supporting device will flip under the action of gravity to the lower side of the bearing platform 210 due to the loss of the supporting force of the transverse plate 300. At this time, the supporting block 211 flipped to the lower side of the bearing platform 210 is rotated so that the first buckle 700 is connected to the second buckle 800, so that the supporting block 211 is fixed under the bearing platform 210.

[0060] In some embodiments, the first buckle 700 includes a first fixing plate 710 and a clamping block 720. The first fixing plate 710 is installed on the supporting block 211, and the clamping block 720 is fixed on the first fixing plate 710. The second buckle 800 includes a second fixing plate 810, a first clamping plate 820 and a second clamping plate 830. The second fixing plate 810 is fixed on the supporting device. The first clamping plate 820 is elastically connected to the second fixing plate 810, and the second clamping plate 830 is elastically connected to the second fixing plate 810. A first opening groove is provided on the first clamping plate 820, and a second opening groove is provided on the second clamping plate 830. The first opening groove and the second opening groove are arranged oppositely. The clamping block 720 is used for being clamped between the first opening groove and the second opening groove.

[0061] Specifically, the first fixing plate 710 is fixed to the bottom surface of the supporting block 211. The surface of the clamping block 720 is an arc structure. The clamping block 720 is fixed to the lower surface of the first fixing plate 710. The second fixing plate 810 is fixed to the lower surface of the bearing platform 210. One end of the first clamping plate 820 is curved to form a first opening groove. One end of the second clamping plate 830 is curved to form a second opening groove. The end of the first opening groove is connected to the lower part of the second fixing plate 810 through an elastic plate. The end of the second opening groove is connected to the lower part of the second fixing plate 810 through an elastic plate. The first opening groove and the first opening groove are arranged oppositely, defining a clamping interval for fitting the clamping block 720. Since both the first clamping plate 820 and the second clamping plate 830 are elastically connected to the second fixing plate 810, the size of this clamping interval can change elastically, and the clamping block 720 can flexibly enter and exit the clamping interval between the first opening groove and the first opening groove.

[0062] In some other embodiments, the first clamping plate 820 is rotatably connected to the second fixing plate 810, the second clamping plate 830 is rotatably connected to the second fixing plate 810, a first elastic member 840 is provided between the first clamping plate 820 and the second fixing plate 810, and a second elastic member 850 is provided between the second clamping plate 830 and the second fixing plate 810.

[0063] Specifically, the end of the first clamping plate 820 bent into the first opening groove is rotatably connected to the middle of the second fixing plate 810 through a rotating shaft. A first elastic member 840 is installed between the horizontal section of the first clamping plate 820 and the second fixing plate 810. The end of the second clamping plate 830 bent to form the second opening groove is rotatably connected to the middle of the second fixing plate 810 through a rotating shaft. A second elastic member 850 is installed between the horizontal section of the second clamping plate 830 and the second fixing plate 810. Both the first elastic member 840 and the second elastic member 850 are springs.

[0064] In some other embodiments, both the first elastic member 840 and the second elastic member 850 are torsion springs. The first elastic member 840 is sleeved on the rotating shaft where the first clamping plate 820 is rotatably connected to the second fixing plate 810, and the second elastic member 850 is sleeved on the rotating shaft where the second clamping plate 830 is rotatably connected to the second fixing plate 810.

[0065] In order to facilitate the transverse movement plate 300 to push and flip the supporting block 211 out from under the bearing platform 210, in some embodiments, the two ends of the transverse movement plate 300 are arc-shaped structures. When the supporting block 211 is connected to the lower part of the bearing platform 210 through the first buckle 700 and the second buckle 800, a chamfer is provided on the edge of the supporting block 211 close to the transverse movement plate 300. When the end of the transverse movement plate 300 abuts against the chamfer of the supporting block 211, the force exerted by the transverse movement plate 300 on the chamfer plane will cause the first buckle 700 and the second buckle 800 to separate.

[0066] In some embodiments, the support switching mechanism further includes a lifting device 400. Along the distribution direction of the two support blocks 211, the lifting device 400 is arranged on the opposite side of the transverse movement driving device 500. The lifting movable end of the lifting device 400 is located below the support block 211. The lifting device 400 is used to push the support block 211 to connect the first buckle 700 and the second buckle 800.

[0067] Specifically, the lifting device 400 and the transverse movement driving device 500 are respectively located on both sides of the base 100. The lifting device 400 includes a fourth support 410 and a lifting cylinder 420. The fourth support 410 is arranged on one side of the base 100. The fourth support 410 and the third support 510 are distributed on both sides of the base 100 respectively. The lifting cylinder 420 is fixed on the fourth support 410, and the telescopic rod of the lifting cylinder 420 is arranged vertically.

[0068] When the support block 211 on one side of the support device flips to the lower side of the carrying platform 210, the lifting cylinder 420 drives the telescopic rod to move upward to push the support block 211 under the carrying platform 210 to connect the first buckle 700 and the second buckle 800.

[0069] It should be noted that when the support block 211 on one side of the support device is pushed to be horizontal through the transverse movement plate 300, and after the support block 211 on the other side of the support device is buckled and connected to the lower side of the carrying platform 210, when it is necessary to push and flip the support block 211 buckled and connected to the lower side of the carrying platform 210 to be horizontal, the lifting device 400 and the transverse movement driving device 500 need to be swapped positions.

[0070] The present invention also provides a support switching method, including the following steps:

[0071] The transverse movement plate 300 slides and pushes the support block 211 on one side of the support device to disconnect the first buckle 700 on the support block 211 from the second buckle 800 on the support device;

[0072] The transverse movement plate 300 continues to push to turn the support block 211 upward to align with the support device and support it;

[0073] The transverse movement plate 300 is staggered from the support block 211 on the other side of the support device, so that the support block 211 on the other side of the support device flips to the lower side of the support device;

[0074] The lifting movable end of the lifting device 400 rises to push the support block 211 that has flipped to the lower side of the support device to connect the first buckle 700 and the second buckle 800.

[0075] Of course, this application is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
