Description

Technical Field

[0001] This invention belongs to the field of capacitor transfer technology, and is particularly related to a hot pressing and unloading device for metal film capacitors. Background Technology

[0002] Existing metal film capacitor hot-pressing equipment has multiple hot-pressing layers, allowing for the simultaneous hot-pressing of multiple layers of metal film capacitors, thus improving hot-pressing efficiency. Before hot pressing, capacitors arranged by an arranging device are pre-flattened using a pre-pressing device to prevent them from rolling during transfer. The capacitors are then transferred to support plates. Once the support plates are full, multiple support plates are manually placed into the multiple hot-pressing layers sequentially to complete the loading. After the hot-pressing equipment completes the process, the support plates are manually removed to complete the unloading. This loading and unloading process is highly dependent on manual operation; workers can only handle one support plate at a time, resulting in low efficiency. Furthermore, the high temperature inside the hot press poses a safety hazard, as workers are prone to burns during loading and unloading. Waiting for the hot press to cool down before removing the capacitors also reduces production efficiency. To address these technical issues, further improvements are needed, requiring the design of a capacitor hot-pressing loading and unloading device to improve both production efficiency and safety. Summary of the Invention

[0003] To address the aforementioned deficiencies in the prior art, this application provides a metal film capacitor hot pressing and unloading device, which enables automatic loading and unloading of metal film capacitors during hot pressing, thereby improving production efficiency and safety.

[0004] To achieve the above objectives, the present invention employs the following techniques:

[0005] A hot-pressing and unloading device for metal film capacitors, comprising:

[0006] A pair of first vertical plates are set on a support platform, and a set of transverse limiting strips are arranged in a vertical array on the inner side of each first vertical plate;

[0007] Multiple first support plates, each having a strip-shaped through groove at both ends that matches the shape of the limiting strip, two sets of limiting strips respectively engaging in the strip-shaped through grooves at both ends of the multiple first support plates, and adjacent first support plates having a first preset distance between them, and a rectangular through groove being formed downward on one side of the top of each first support plate.

[0008] A push block is located on the side of the first support plate near the rectangular through slot. The push block is connected to the movable end of a linear mechanism and is used to push multiple first support plates into multiple hot-pressing layers of the hot-pressing equipment after they have risen. On the side of the push block facing the first support plate, multiple transverse connecting plates are provided in the vertical direction. Each connecting plate has a baffle at the end away from the push block. The bottom of the baffle protrudes from the bottom of the connecting plate. Each connecting plate has a push plate hinged to its bottom. The rotation axis of the push plate is parallel to the length direction of the first support plate. When the push plate is in a vertical state, the push plate abuts against the inner side of the baffle. When the push block moves to abut against the first support plate, the multiple push plates are respectively in multiple rectangular through slots, and the push plate and the side of the rectangular through slot near the push block have a second preset distance.

[0009] Furthermore, the two sets of limiting strips are slidably connected to a pair of first vertical plates in the vertical direction. Each of the first vertical plates has a set of strip-shaped horizontal plates along the vertical direction on its outer side. The two sets of strip-shaped horizontal plates are connected to the two sets of limiting strips respectively. Each of the two sets of strip-shaped horizontal plates is connected to a lifting belt. The length of the lifting belt section between the upper and lower adjacent strip-shaped horizontal plates is the same. The top of the two lifting belts is connected to the telescopic end of a lifting mechanism. When the telescopic end of the lifting mechanism is fully extended, the lifting belt is in a bent state, and the connecting plate and the push plate are outside the coverage area of ​​the first support plate near the push block. When the telescopic end of the lifting mechanism is fully retracted, the bottom first support plate rises to match the height of the bottom hot-pressed layer after rising in the hot-pressing equipment, and there is a first preset distance between the upper and lower adjacent first support plates.

[0010] Furthermore, a U-shaped fixing plate is provided above the support platform. The two vertical sections of the U-shaped fixing plate are connected to the support platform. The fixed end of the lifting mechanism is connected to the horizontal section of the U-shaped fixing plate. The telescopic end of the lifting mechanism is connected to the middle of a lifting plate. Two lifting belts are fixed to both ends of the lifting plate respectively.

[0011] Furthermore, support components are provided on the outer sides of both sets of strip horizontal plates. The support components include a pair of fixed rods, a pair of vertical rods, and multiple second support plates. The multiple second support plates are rotatably connected between the pair of fixed rods. The pair of fixed rods are vertically fixed above the support platform. The pair of vertical rods are rotatably connected to the ends of the multiple second support plates away from the strip horizontal plates on both sides. One of the vertical rods is hinged to the telescopic end of a cylinder. The fixed end of the cylinder is hinged to the vertical section on the same side. When the telescopic end of the cylinder is fully extended and the telescopic end of the lifting mechanism is fully extended, the top of the second support plate abuts against the bottom of the multiple strip horizontal plates above the bottommost strip horizontal plate. The distance between adjacent first support plates matches the height of the pre-flattened capacitor.

[0012] Furthermore, support columns are provided above several strips below the topmost strip, and the height of the support columns is less than the height of the capacitor after it has been hot-pressed.

[0013] Furthermore, each of the two sets of strip-shaped horizontal plates is provided with a pair of support components on its outer side. The pair of support components are symmetrically arranged with respect to the lifting belt on the same side. A synchronizing rod is connected between the two opposing vertical rods in the pair of support components, and the telescopic end of the cylinder is rotatably connected to the synchronizing rod.

[0014] Furthermore, the linear mechanism is a lead screw module, which is located below the support platform. A receiving groove is provided in the middle of the platform, extending through both sides, to receive the movable end of the linear mechanism. A push block is located above the movable end of the linear mechanism, with the side of the push block near the first support plate protruding from the side of the movable end of the linear mechanism near the first support plate.

[0015] Furthermore, the support platform is provided with two sets of rollers on the side near the rectangular through slot. The two sets of rollers are rotatably connected to two fixed plates. The length direction of the fixed plates is parallel to the width direction of the first support plate, and the rotation axis of the rollers is parallel to the length direction of the first support plate. A linear mechanism is provided between the two sets of rollers, and the height of the top of the rollers matches the height of the bottom of the first support plate.

[0016] Furthermore, a set of vertical limiting rollers are provided at intervals on the outer side of a fixed plate. The limiting rollers are rotatably mounted in a fixed frame, which is fixed to the fixed plate. When the first support plate moves along the limiting strip to one side of the limiting roller, the first support plate abuts against the limiting roller.

[0017] Furthermore, the first vertical plate has multiple vertical grooves, and the limiting strip and the strip-shaped horizontal plate are connected by multiple rectangular blocks. The multiple rectangular blocks are slidably connected in the multiple vertical grooves, and the limiting strip and the strip-shaped horizontal plate abut against the two sides of the first vertical plate respectively.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. Multiple first support plates can be pushed into multiple raised hot pressing layers of the hot pressing equipment simultaneously by the pusher block to achieve automatic feeding. After hot pressing is completed, multiple first support plates can be pulled out of the hot pressing equipment by the pusher plate and rectangular through slot to achieve automatic unloading.

[0020] 2. The lifting belt can drive the strip plate to descend, and after hot pressing, multiple first support plates can be stacked up and down, which makes it easier to push multiple first support plates out of the limit strip at the same time, improving the material unloading efficiency. The support component pushes the strip plate up, which can align the limit strip with multiple first support plates with pre-flattened capacitors placed on them and stacked before loading, improving the loading efficiency.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0037] This application provides a hot-pressing and unloading device for metal film capacitors, such as... Figures 1-14 As shown, it includes a first vertical plate 1, a first support plate 3, a pusher block 4, etc.

[0038] Specifically, there is a pair of first vertical plates 1, each fixed to a support platform 101. A set of horizontal limiting strips 2 are arranged in a vertical array on the inner side of each first vertical plate 1. There are multiple first support plates 3, each with a rectangular through-slot 302 extending downwards on one side of its top. Both ends of each first support plate 3 have strip-shaped through-slots 301 matching the shape of the limiting strips 2. The two sets of limiting strips 2 are respectively engaged within the strip-shaped through-slots 301 at both ends of the multiple first support plates 3. Adjacent first support plates 3 have a first preset distance between them. Specifically, when multiple hot-pressing layers of the hot-pressing equipment are raised, the bottom height of the multiple first support plates 3 matches the bottom and top height of the multiple hot-pressing layers of the hot-pressing equipment. A push block 4 is located on the side of the first support plate 3 near the rectangular through-slot 302. The push block 4 is connected to the movable end 501 of a linear mechanism 5, used to hold the multiple first support plates 3... On the multiple raised hot-pressed layers pushed into the hot-pressing equipment, the pusher block 4 is provided with multiple horizontal connecting plates 401 in the vertical direction on the side facing the first support plate 3. Each connecting plate 401 is provided with a baffle 402 at the end away from the pusher block 4. The bottom of the baffle 402 protrudes from the bottom of the connecting plate 401. Each connecting plate 401 is hinged to a pusher plate 403. The rotation axis of the pusher plate 403 is parallel to the length direction of the first support plate 3. When the pusher plate 403 is in a vertical state, the pusher plate 403 abuts against the inner side of the baffle 402. When the pusher block 4 moves to abut against the first support plate 3, the multiple pushers 403 are respectively in multiple rectangular through slots 302, and the pusher plate 403 and the side of the rectangular through slot 302 near the pusher block 4 have a second preset distance. The second preset distance is specifically set so that the pusher plate 403 can rotate downward from above the rectangular through slot 302 to a vertical state.

[0039] In actual use, the device is placed directly in front of the hot press equipment, so that the multiple first support plates 3 are aligned with the multiple hot press layers of the hot press equipment. When hot pressing is required, pre-flattened capacitors 8 are placed sequentially above multiple first support plates 3. Then, multiple first support plates 3 are placed back between the two sets of limiting strips 2. Next, the movable end 501 of the linear mechanism 5 is controlled to drive the push block 4 to move towards the first support plate 3. When the push plate 403 abuts against the first support plate 3 and continues to move, the push plate 403 will rotate upward to reach above the first support plate 3. When the push plate 403 reaches above the rectangular through groove 302, it will rotate downward to a vertical state due to its own gravity. As the push block 4 continues to move forward, the push block 4 can simultaneously push multiple first support plates 3 into the multiple hot pressing layers after the hot pressing equipment has risen. Then, the hot pressing equipment is started. When the multiple hot pressing layers after the hot pressing equipment have fallen down until the push plate 403 has completely left the rectangular through groove 302, the linear mechanism 5 is controlled to drive the push block 4 to retract, so that the baffle 402 and the push plate 403 are outside the coverage area of ​​the hot pressing layers of the hot pressing equipment, so as to avoid blocking the descent of multiple hot pressing layers and complete the loading of capacitors 8. After the hot pressing is completed and multiple hot-pressed layers rise, the linear mechanism 5 is controlled to drive the push block 4 to move towards the first support plate 3, so that the push plate 403 enters the rectangular through groove 302. Then, the linear mechanism 5 is controlled to drive the push block 4 to move away from the first support plate 3. When the baffle 402 abuts against the side of the rectangular through groove 302 near the push block 4, the push plate 403 will be blocked by the baffle 402 and will not rotate upward. This will push the first support plate 3 away from the hot pressing equipment and into the space between the two sets of limit bars 2, thus completing the unloading of the capacitor 8.

[0040] Preferred options, please refer to Figures 5-8In one embodiment, two sets of limiting strips 2 are slidably connected to a pair of first vertical plates 1 in the vertical direction. A set of strip-shaped horizontal plates 201 is provided on the outer side of each first vertical plate 1 in the vertical direction. The two sets of strip-shaped horizontal plates 201 are connected to the two sets of limiting strips 2 respectively. A lifting belt 6 is connected to the outer side of each set of strip-shaped horizontal plates 201. The length of the lifting belt 6 between the upper and lower adjacent strip-shaped horizontal plates 201 is the same, so that when the lifting belt 6 is straightened, the distance between the upper and lower adjacent strip-shaped horizontal plates 201 is the same. Specifically, the tops of the two lifting belts 6 are connected to the telescopic end of a lifting mechanism 7. When the telescopic end of the lifting mechanism 7 is fully extended and the pre-flattened capacitor 8 is placed on the first support plate 3, the lifting belts 6 are in a bent state, and the connecting plate 401 and the push plate 403 are outside the coverage area of ​​the first support plate 3 near the push block 4. When the telescopic end of the lifting mechanism 7 is fully retracted, there is a first preset distance between the upper and lower adjacent first support plates 3, and the bottom first support plate 3 moves upward to match the height of the bottom hot-pressed layer after rising in the hot-pressing equipment. Specifically, the distance that the bottom first support plate 3 moves upward is greater than the height of the push plate 403 in the rectangular through groove 302 below the top of the corresponding first support plate 3, so that when the bottom first support plate 3 descends to the maximum extent, the corresponding push plate 403 can disengage from the rectangular through groove 302.

[0041] After placing multiple first support plates 3 containing pre-flattened capacitors 8 between two sets of limiting strips 2, the telescopic end of the lifting mechanism 7 is retracted, driving the two lifting belts 6 to move upward to their maximum extent. This allows the multiple first support plates 3 to align with the multiple raised hot-pressed layers in the hot-pressing equipment. The first support plates 3 are then pushed into the hot-pressing equipment by the push block 4. After hot pressing is completed, the first support plates 3 are pushed between the two sets of limiting strips 2 by the push plate 403. The telescopic end of the lifting mechanism 7 is then pushed out, causing the multiple first support plates 3 to descend. When the first support plates 3 descend until the push plate 403 is completely disengaged from the rectangular through slot 302, the linear mechanism 5 is controlled to drive the push block 4 to move away from the first support plates 3. This method avoids the connecting plate 401 blocking the descent of the first support plates 3, allowing the multiple first support plates 3 and the capacitors 8 above them to overlap. This facilitates the subsequent direct push of the multiple first support plates 3 out of the limiting strips 2 to transfer the capacitors 8.

[0042] For details, please refer to Figure 8 , Figure 9 The first vertical plate 1 has multiple vertical grooves 102. The limiting strip 2 and the strip horizontal plate 201 are connected by multiple rectangular blocks 202. The multiple rectangular blocks 202 are slidably connected in the multiple vertical grooves 102, and the limiting strip 2 and the strip horizontal plate 201 abut against the two sides of the first vertical plate 1 respectively. In this way, the limiting strip 2 and the strip horizontal plate 201 move up and down synchronously on the first vertical plate 1.

[0043] For details, please refer to Figure 8 A U-shaped fixing plate 9 is provided above the support platform 101. The two vertical sections 901 of the U-shaped fixing plate 9 are connected to the support platform 101. The fixed end of the lifting mechanism 7 is connected to the horizontal section 902 of the U-shaped fixing plate 9. The telescopic end of the lifting mechanism 7 is connected to the middle of a lifting plate 701. Two lifting belts 6 are fixed to both ends of the lifting plate 701 respectively. When the telescopic end of the lifting mechanism 7 moves up and down, it can drive the two lifting belts 6 to rise and fall synchronously through the lifting plate 701.

[0044] For details, please refer to Figure 8 The linear mechanism 5 is a lead screw module, which facilitates control over the distance of pushing and pulling the push block 4. The lead screw module is located below the platform 1011 of the support table 101. The platform 1011 has a receiving groove 1012 extending through both sides in the middle to receive the movable end 501 of the linear mechanism 5. The push block 4 is located above the movable end 501 of the linear mechanism 5. The side of the push block 4 near the first support plate 3 protrudes from the side of the movable end 501 of the linear mechanism 5 near the first support plate 3. When the movable end 501 of the linear mechanism 5 moves to its maximum extent toward the hot press, the distance the first support plate 3 is pushed out can be increased because the push block 4 protrudes from the movable end 501 of the linear mechanism 5. This avoids the situation where the first support plate 3 cannot be pushed into the hot press due to the restriction of the bottom of the hot press when the linear mechanism 5 is installed. More specifically, the lead screw module includes a lead screw 503, a drive motor 502, and a movable block. The lead screw 503 is rotatably connected between a pair of second vertical plates 504. One of the second vertical plates 504 is fixed to the outward side of the support platform, and the other second vertical plate 504 is spaced apart on the other side of the support platform. The lead screw 503 is rotatably connected between the pair of second vertical plates 504. A guide rod 505 parallel to the lead screw 503 is provided between the second vertical plates 504. The movable block is the movable end 501 of the linear mechanism 5. It is slidably connected to the guide rod 505 and threadedly connected to the lead screw 503. The output shaft of the drive motor 502 is connected to one end of the lead screw 503. The lead screw 503 and the guide rod 505 are both located in the receiving groove 1012.

[0045] Preferred options, please refer to Figures 10-13Both sets of strip horizontal plates 201 are provided with support components 10 on their outer sides. After the lifting belt 6 is lowered, it supports multiple strip horizontal plates 201 above the bottom strip horizontal plate 201, so that the adjacent first support plates 3 maintain a first preset distance. In this way, multiple first support plates 3 with pre-flattened capacitors 8 can be stacked before loading. Because the strip horizontal plate 201 is supported by the support components 10, multiple first support plates 3 with pre-flattened capacitors 8 and stacked can be aligned with the corresponding limit strips 2. By pushing multiple first support plates 3 toward the limit strips 2, multiple first support plates 3 can be inserted between the two sets of limit strips 2, further improving loading efficiency. Specifically, the support assembly 10 includes a pair of fixed rods 1001, a pair of vertical rods 1002, and multiple second support plates 1003. The multiple second support plates 1003 are rotatably connected between the pair of fixed rods 1001. The pair of fixed rods 1001 are vertically fixed above the support platform 101. The pair of vertical rods 1002 are rotatably connected to the ends of the multiple second support plates 1003 on both sides away from the strip-shaped horizontal plate 201. One of the vertical rods 1002 is hinged to the telescopic end of a cylinder 1004. The fixed end of the cylinder 1004 is connected to the telescopic end of the cylinder 1004. The vertical section 901 on the side is hinged. When the telescopic end of the cylinder 1004 is fully extended and the telescopic end of the lifting mechanism 7 is fully extended, the top of the second support plate 1003 abuts against the bottom of multiple strip horizontal plates 201 above the bottommost strip horizontal plate 201. The distance between adjacent first support plates 3 matches the height of the pre-flattened capacitor 8. When the telescopic end of the cylinder 1004 is fully retracted, the second support plate 1003 rotates to outside the coverage area of ​​the bottom of the strip horizontal plate 201 to avoid blocking the rise of the strip horizontal plate 201.

[0046] For details, please refer to Figure 11Above the topmost strip horizontal plate 201, there are multiple strip horizontal plates 201 with support columns 2011. When multiple first support plates 3 are placed on top of hot-pressed capacitors 8 and stacked one on top of the other, the height of the support column 2011 is less than the height of the corresponding hot-pressed capacitors 8 on the first support plate 3. Because the height of the capacitor 8 after hot pressing will be less than the height of the pre-flattened capacitor 8, during the unloading process, when multiple first support plates 3 reach between the two sets of limiting strips 2 and descend to their maximum extent, if the second support plate 1003 rotates to push up the strip horizontal plate 201, the top of the hot-pressed capacitor 8 will have a certain gap with the upper first support plate 3, making it inconvenient to push multiple first support plates 3 out of the two sets of limiting strips 2 simultaneously. If the second support plate 1003 rotates to outside the bottom coverage area of ​​the strip horizontal plate 201, after the first support plate 3 is pushed out of the two sets of limiting strips 2, multiple strip horizontal plates 201 will descend to abut against each other, and the second support plate 1003 will not be able to rotate to the bottom of the corresponding strip horizontal plate 201 to push up the strip horizontal plate 201. After setting the support column 2011, even if the first support plate 3 is pushed out of the two sets of limiting strips 2, the strip horizontal plate 201 will not descend to abut against each other, and the second support plate 1003 can rotate to push the strip horizontal plate 201 up. Therefore, during the unloading process, when the telescopic end of the lifting mechanism 7 is fully extended, the top of the capacitor 8 after hot pressing will abut against the first support plate 3 above, and multiple first support plates 3 can be pushed out of the two sets of limiting strips 2 at the same time. Then, the telescopic end of the control cylinder 1004 is fully extended, so that the second support plate 1003 rotates to push the strip horizontal plate 201 up, so that multiple first support plates 3 with pre-flattened capacitors 8 placed on them and stacked can be aligned with the two sets of limiting strips 2.

[0047] For more details, please refer to Figure 12 , Figure 13 Each of the two sets of strip horizontal plates 201 has a pair of support components 10 on its outer side. The pair of support components 10 are symmetrically arranged with respect to the lifting belt 6 on the same side. A synchronizing rod 1005 is connected between the two opposing vertical rods 1002 in the pair of support components 10. The telescopic end of the cylinder 1004 is rotatably connected to the synchronizing rod 1005. The cylinder 1004 drives the synchronizing rod 1005 to move, which can drive the second support plate 1003 in the pair of support components 10 to rotate synchronously and push the strip horizontal plate 201 up, thereby improving the stability of pushing the strip horizontal plate 201 up.

[0048] Preferred options, please refer to Figure 14Two sets of rollers 11 are provided on the side of the support platform 101 near the rectangular through slot 302. The two sets of rollers 11 are rotatably connected to two fixed plates 12. The length direction of the fixed plates 12 is parallel to the width direction of the first support plate 3, and the rotation axis of the rollers 11 is parallel to the length direction of the first support plate 3. A linear mechanism 5 is located between the two sets of rollers 11, and the top height of the rollers 11 matches the bottom height of the bottom of the first support plate 3. During the feeding process, the first support plate 3 is pushed above the two sets of rollers 11, which reduces friction during the pushing process. For details, please refer to [link to relevant documentation]. Figure 14 A set of vertical limiting rollers 13 are provided at intervals on the outer side of a fixed plate 12. The limiting rollers 13 are rotatably mounted in a fixed frame 14, which is fixed to the fixed plate 12. When the first support plate 3 moves along the limiting strip 2 to one side of the limiting roller 13, the first support plate 3 abuts against the limiting roller 13. During feeding, the first support plate 3 can be placed on two sets of rollers 11, and then one side of the first support plate 3 can abut against the limiting roller 13 to achieve the alignment of the first support plate 3 with the limiting strip 2. Then, the linear mechanism 5 is controlled to drive the push block 4 to push the first support plate 3, which can push the first support plate 3 between the two sets of limiting strips 2.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to be the only or limiting of the invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from its scope are all within the protection scope of the present invention.
