Description

Technical Field

[0001] This utility model relates to the technical field of energy storage box cover processing, specifically an automatic loading and unloading device for vacuum forming of energy storage box covers. Background Technology

[0002] An energy storage box is a modular device used to store electrical energy, typically integrating a battery system, energy management system, and power conversion device. The box structure usually employs a modular design, with its core components being the top cover, lower casing, and side panels. The manufacturing methods for the top cover vary, depending on materials, processes, cost, and performance requirements. These include composite material molding, vacuum forming, and sheet metal processing, while materials such as plastics and reinforced polypropylene are suitable for lightweight applications and special performance requirements.

[0003] When existing energy storage box covers are manufactured using a thermoforming process, automated equipment can sequentially control the feeding of plastic materials and the unloading of the energy storage box cover after it is formed. Through program settings, the feeding and unloading operations can be performed separately. However, if one of the mechanical structures malfunctions, the other mechanical structures cannot stop working automatically. This requires high precision in the coordination between multiple mechanical structures, which leads to cumbersome operation and affects the efficiency of feeding and unloading. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic loading and unloading device for the thermoforming process of energy storage box covers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic loading and unloading device for thermoforming an energy storage box cover includes a base and a processing position mounted on the base. A placement plate that can be aligned with the processing position is slidably disposed on the base. A reciprocating pusher is installed on the base to control the sliding of the placement plate relative to the base. Parallel linkage mechanisms are symmetrically arranged on the base; A clamping member, connected to the parallel linkage mechanism, is used to perform a clamping motion when the parallel linkage mechanism drives the clamping member to move above the workpiece; An intermittent drive component is installed at the lower end of the base and controls the reciprocating push component, the parallel linkage mechanism, and the clamping component, respectively.

[0009] The automatic loading and unloading device for thermoforming the energy storage box cover as described above: the clamping component includes a connecting shaft rotatably mounted on the support plate, a second sliding groove symmetrically formed on the connecting shaft, a sleeve sleeved along the axis of the connecting shaft, and a first ball bearing movably disposed on the inner wall of the sleeve and slidingly engaging with the second sliding groove; It also includes symmetrically arranged clamps, which are slidably disposed on the support plate and fixed to the sleeve.

[0010] The automatic loading and unloading device for the thermoforming of the energy storage box cover as described above: the bottom of the base is fixedly provided with a support seat to support the movement of the intermittent drive component.

[0011] The automatic loading and unloading device for the thermoforming of the energy storage box cover as described above: the intermittent drive component includes: A lead screw is rotatably mounted on the receiving seat. The lead screw is driven to rotate by a motor mounted on the receiving seat. A threaded sleeve is threadedly connected to the lead screw, and a connecting collar is installed on the threaded sleeve. A first sleeve and a second sleeve are respectively fixed at both ends of the connecting collar. The first drive shaft is rotatably mounted on the receiving seat and is connected to the first rotating shaft rotatably mounted on the receiving seat via a third toothed belt. The first rotating shaft is connected to the first movable shaft via a fourth toothed belt. The second drive shaft is rotatably mounted on the receiving seat and is connected to an intermittent transmission component, which controls the rotation of the connecting shaft and the second movable shaft respectively.

[0012] The automatic loading and unloading device for the thermoforming of the energy storage box cover as described above: the intermittent transmission component includes a Maltese cross mechanism, which is divided into a drive wheel, a first driven wheel, and a second driven wheel, and the second transmission shaft is fixed to the drive wheel; The first driven shaft is rotatably mounted on the receiving seat and fixed to the first driven wheel. The second movable shaft is connected to the third rotating shaft rotatably mounted on the base via the fifth toothed belt. The second rotating shaft is rotatably mounted on the receiving seat. The two ends of the second rotating shaft are respectively connected to the first driven shaft and the third rotating shaft via the first bevel gear set.

[0014] Compared with the prior art, the beneficial effects of this utility model are: After the energy storage box cover is formed on the placement plate, the intermittent drive component is activated, driving the reciprocating pusher to push the placement plate, causing it to move relative to the base and completely separate from the processing position. When it reaches the forming end, the reciprocating pusher stops pushing the placement plate. At this time, the parallel linkage mechanism deflects above the energy storage box cover, and the clamping component clamps the energy storage box cover. After the energy storage box cover is clamped, the parallel linkage mechanism resets, causing the energy storage box cover to be transferred to the designated position, allowing it to quickly detach from the placement plate. After reaching the designated position, the clamping component releases, and then the reciprocating pusher resumes its operation to reset the placement plate. This achieves automatic unloading of the energy storage box cover, preventing it from being bumped and allowing for rapid transfer of the formed cover, freeing up storage space on the placement plate and further improving the automatic loading and unloading efficiency of the energy storage box cover thermoforming process.

Detailed Implementation

[0024] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0025] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0026] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0027] Please see Figures 1-8 In this embodiment of the utility model, an automatic loading and unloading device for thermoforming an energy storage box cover includes a base 1 and a processing position 2 installed on the base 1. A placement plate 3 that can be aligned with the processing position 2 is slidably disposed on the base 1. A reciprocating pusher is installed on the base 1 to control the sliding of the placement plate 3 relative to the base 1. Parallel linkage mechanisms are symmetrically arranged on the base 1; A clamping member, connected to the parallel linkage mechanism, is used to perform a clamping motion when the parallel linkage mechanism drives the clamping member to move above the workpiece; An intermittent drive component is installed at the lower end of the base 1 to control the reciprocating push component, the parallel linkage mechanism, and the clamping component, respectively.

[0028] In this embodiment, after the energy storage box cover on the placement plate 3 is formed, the intermittent drive component is activated to drive the reciprocating pusher to push the placement plate 3, causing the placement plate 3 to move relative to the base 1 and completely separate from the processing position 2. When it moves to the forming end, the reciprocating pusher stops pushing the placement plate 3. At this time, the parallel linkage mechanism deflects above the energy storage box cover, and the clamping component clamps the energy storage box cover. After the energy storage box cover is clamped, the parallel linkage mechanism resets and drives the energy storage box cover to the designated position, so that the energy storage box cover can quickly detach from the placement plate 3. After reaching the designated position, the clamping component releases, and then the reciprocating pusher works again to drive the placement plate 3 to reset, thereby realizing automatic unloading of the energy storage box cover. This avoids the energy storage box cover being bumped and can quickly transfer the energy storage box cover, accelerating the reset of the placement plate 3 to facilitate secondary vacuum forming of the energy storage box cover.

[0029] For further solutions to this utility model, please refer to [link / reference]. Figure 6The reciprocating pusher includes a first movable shaft 4 rotatably mounted on the base 1. A first sliding groove 401 is formed on the first movable shaft 4. A connecting cylinder 24 fixed to the placement plate 3 is arranged along the axial direction of the first movable shaft 4. A fourth ball bearing 2401 that slides and engages with the first sliding groove 401 is movably arranged on the inner wall of the connecting cylinder 24.

[0030] Driven by the intermittent drive component, when the first movable shaft 4 rotates, the first groove 401 on it exerts an inclined force on the fourth ball 2401, causing the connecting cylinder 24 to move linearly along the axial direction of the first movable shaft 4. When the fourth ball 2401 moves to the end of the first groove 401, the first movable shaft 4 stops rotating, so that the placement plate 3 is completely separated from the processing position 2, avoiding interference with the loading device above the processing position 2 when the parallel linkage mechanism deflects.

[0031] For further solutions to this utility model, please refer to [link / reference]. Figure 3 and Figure 5 The parallel linkage mechanism includes two parallel connecting rods 5 and a support plate 6 parallel to the base 1. The two ends of the connecting rods 5 are rotatably connected to the base 1 and the support plate 6, respectively, and the connecting rods 5 are controlled by a reciprocating moving part mounted on the base 1 to perform reciprocating deflection.

[0032] The reciprocating moving part includes a second movable shaft 31 rotatably mounted on the base 1, a third sliding groove 3101 formed on the second movable shaft 31, a moving cylinder 32 sleeved along the axial direction of the second movable shaft 31, and a fifth ball bearing 3201 movably disposed on the inner wall of the moving cylinder 32 and slidingly engaged with the third sliding groove 3101. It also includes a slider 33, which is slidably disposed on the connecting rod 5, and the slider 33 is hinged to the end of the moving cylinder 32 away from the second movable shaft 31.

[0033] When the placement plate 3 moves to the end of its stroke, the second movable shaft 31 rotates under the control of the intermittent drive component, causing the third slide groove 3101 on it to exert an inclined force on the fifth ball 3201. The connecting rod 5 reciprocates in a direction parallel to the axis of the second movable shaft 31, thus restricting the moving cylinder 32. The moving cylinder 32 can move linearly along the axis of the second movable shaft 31. When the moving cylinder 32 moves, it drives the connecting rod 5 to deflect in the direction of the placement plate 3. During the deflection process, the slider 33 slides relative to the connecting rod 5. When the fifth ball 3201 moves to the end of the third slide groove 3101, the connecting rod 5 stops deflecting. At this time, the support plate 6 is located on the energy storage box cover, so that the clamping component can clamp the energy storage box cover.

[0034] For further solutions to this utility model, please refer to [link / reference]. Figure 4The clamping member includes a connecting shaft 7 rotatably mounted on the support plate 6. A second sliding groove 701 is symmetrically formed on the connecting shaft 7. A sleeve 10 is sleeved along the axial direction of the connecting shaft 7. A first ball bearing 1001 that slides and engages with the second sliding groove 701 is movably disposed on the inner wall of the sleeve 10. It also includes symmetrically arranged clamping plates 12, which are slidably disposed on the support plate 6 and fixed to the sleeve 10.

[0035] In the constant state, the purpose of keeping the connecting rod 5 away from the placement plate 3 is to avoid interference between the side plate on the placement plate 3 and the clamping plate 12.

[0036] When the support plate 6 moves to the top of the energy storage box cover, the connecting shaft 7 rotates under the control of the intermittent drive component. When the connecting shaft 7 rotates, the second sliding groove 701 on it tilts the first ball 1001, causing the two clamping plates 12 to move closer to each other. The two clamping plates 12 abut against the two ends of the energy storage box cover and clamp it, so that when the connecting rod 5 deflects and resets again, the energy storage box cover can move synchronously with the movement of the clamping plates 12, so as to separate the energy storage box cover from the placement plate 3 and speed up the automatic unloading of the energy storage box cover. After being transferred to the designated area, the clamping plates 12 give up clamping and resetting the energy storage box cover, preparing for the next transfer operation.

[0037] For further solutions to this utility model, please refer to [link / reference]. Figure 7 and Figure 8 The base 1 has a fixed support seat at its bottom to support the movement of the intermittent drive component.

[0038] The intermittent drive includes: A lead screw 14 is rotatably mounted on the receiving seat. The lead screw 14 is driven to rotate by a motor 13 mounted on the receiving seat. A threaded sleeve 17 is threadedly connected to the lead screw 14, and a connecting clamp 19 is installed on the threaded sleeve 17. A first sleeve 16 and a second sleeve 18 are respectively fixed at both ends of the connecting clamp 19. The first drive shaft 15 is rotatably mounted on the support seat and is connected to the first rotating shaft 22 rotatably mounted on the support seat via the third toothed belt 21. The first rotating shaft 22 is connected to the first movable shaft 4 via the fourth toothed belt 23. The second drive shaft 20 is rotatably mounted on the receiving seat and is connected to an intermittent transmission component, which controls the rotation of the connecting shaft 7 and the second movable shaft 31 respectively.

[0039] The intermittent transmission component includes a Maltese cross mechanism 25, which is divided into a drive wheel, a first driven wheel, and a second driven wheel. The second transmission shaft 20 is fixed to the drive wheel. The first driven shaft 26 is rotatably mounted on the support and fixed to the first driven wheel. The second movable shaft 31 is connected to the third rotating shaft 29 rotatably mounted on the base 1 via the fifth toothed belt 30. The second rotating shaft 28 is rotatably mounted on the support. The two ends of the second rotating shaft 28 are respectively connected to the first driven shaft 26 and the third rotating shaft 29 via the first bevel gear set 27. The second driven shaft 34 is rotatably mounted on the receiving seat and fixed to the second driven wheel. It is connected to the fourth rotating shaft 36 rotatably mounted on the receiving seat through a gear set 35. The fourth rotating shaft 36 is connected to the fifth rotating shaft 38 rotatably mounted on the base 1 through a second bevel gear set 37. The fifth rotating shaft 38 is connected to the central rotating shaft 8 rotatably mounted on the base 1 through a second toothed belt 11. The central rotating shaft 8 is connected to the connecting shaft 7 through a first toothed belt 9.

[0040] Preferably, the first sleeve 16 and the second sleeve 18 are connected along the first drive shaft 15 and the second drive shaft 20, respectively; A second ball bearing 1601 is movably disposed on the inner wall of the first sleeve 16, and a first limiting groove 1501 is formed on the first drive shaft 15 to slide with the second ball bearing 1601. A third ball bearing 1801 is movably disposed on the inner wall of the second sleeve 18, and a second limiting groove 2001 is formed on the second drive shaft 20 to slide and engage with the third ball bearing 1801.

[0041] It should be noted that: the first limiting groove 1501 is divided into threaded groove A, straight groove B, and threaded groove C; the second limiting groove 2001 is divided into straight groove a, threaded groove b, and straight groove c. In the initial state, the second ball 1601 is located in threaded groove A or threaded groove C, and the third ball 1801 is located in straight groove a or straight groove c.

[0042] In detail, when the energy storage box cover on the placement plate 3 needs to be formed, the motor 13 is started. The output shaft of the motor 13 is fixed to the lead screw 14, so that when the output shaft rotates, it drives the lead screw 14 to rotate synchronously. When the lead screw 14 rotates, it drives the threaded sleeve 17 to move linearly along the axis of the lead screw 14. When the threaded sleeve 17 moves, it drives the connecting clamp 19 to move accordingly, so as to realize the need for the first sleeve 16 and the second sleeve 18 to move relative to the first drive shaft 15 and the second drive shaft 20, respectively.

[0043] When the first sleeve 16 moves relative to the first drive shaft 15, the second ball 1601 is located in the A thread groove or the C thread groove. At this time, the first drive shaft 15 rotates, while the third ball 1801 is located in the a straight groove or the c straight groove. The second drive shaft 20 does not rotate. When the first drive shaft 15 rotates, the first movable shaft 4 can be rotated through transmission, pushing the placement plate 3 so that the placement plate 3 can be separated from the processing position 2, thereby effectively avoiding interference between the feeding device and the connecting rod 5.

[0044] When the second ball 1601 moves into the straight groove B, the third ball 1801 moves into the threaded groove b. At this time, the first drive shaft 15 stops rotating, while the second drive shaft 20 rotates. Through the intermittent transmission of the Maltese cross mechanism 25, the control link 5 deflects. When the support plate 6 moves to the upper end of the energy storage box cover, the link 5 stops deflecting, and the clamping plate 12 performs a clamping action on the energy storage box cover. Subsequently, the link 5 deflects and resets again, so that the energy storage box cover can be separated from the placement plate 3 and transferred to the designated area. Then, the clamping plate 12 abandons the clamping action on the energy storage box cover, thereby realizing the automatic unloading action of the energy storage box cover.

[0045] After the energy storage box cover is transferred, the second ball 1601 moves to the A thread groove or the C thread groove, and the third ball 1801 moves to the a straight groove or the c straight groove to realize the reset of the placement plate 3. The motor 13 is a servo motor, which can control the forward and reverse rotation of the lead screw 14.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
