Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery production equipment, and particularly relates to a container door opening device. BACKGROUND

[0002] The energy storage battery pack is generally stacked in each storage unit in the container for convenient transportation and management. Since the battery pack is heavy, the automatic container loading equipment is generally used to load the battery pack into each storage unit in the container in sequence.

[0003] In order to protect the battery pack and facilitate the inspection of the battery pack, each storage unit is closed by a hinged unit door. Therefore, the automatic container loading equipment usually needs to be provided with a door opening device to automatically open or close the unit door of the storage unit.

[0004] The existing door opening device usually comprises a driving mechanism and a suction assembly. The driving mechanism drives the suction assembly to adsorb the unit door and then drives the suction assembly to move, so as to open the adsorbed unit door. However, the track of the movement of the suction assembly driven by the driving mechanism is preset by the worker according to the size of the unit door. When the preset track deviates from the actual movement track of the unit door, the suction assembly will be offset relative to the unit door in the process of rotating the unit door driven by the suction assembly, and there is a risk that the suction assembly will fall off the unit door.

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0051] The energy storage battery pack is generally stacked in each storage unit in the container, which is convenient for transportation and management. Since the battery pack is heavy, the battery pack is generally sequentially loaded into each storage unit in the container by an automatic loading device.

[0052] To protect the battery pack and facilitate its inspection, each storage unit is closed by a hinged unit door. Therefore, automated packing equipment usually needs to be equipped with a door opening device to automatically open or close the unit door of the storage unit.

[0053] Existing door opening devices typically include a drive mechanism and an adsorption assembly. The drive mechanism drives the adsorption assembly to adsorb the unit door, and then drives the adsorption assembly to move, thus opening the adsorbed unit door. However, the trajectory of the drive mechanism driving the adsorption assembly is preset by the operator based on the unit door size. But when there is a deviation between the preset trajectory and the actual movement trajectory of the unit door, the adsorption assembly will shift relative to the unit door during the rotation of the unit door, posing a risk that the adsorption assembly will detach from the unit door.

[0054] Therefore, this application proposes a container door opening device; please refer to [link / reference]. Figure 1 and Figure 2 As shown, inside container 10 along the first horizontal direction ( Figure 1 The container door opening device proposed in this application includes a frame 20, a drive mechanism 30, and at least one adsorption mechanism 40. The adsorption mechanism 40 includes a base 41, a sliding member 42, and an adsorption member 43. The sliding member 42 is slidably mounted on the base 41 in a first horizontal direction, and the adsorption member 43 is mounted on the sliding member 42. The adsorption member 43 is configured to adsorb or release the unit door 12. The drive mechanism 30 is mounted on the frame 20, and the drive end of the drive mechanism 30 is connected to the base 41. The drive mechanism 30 is configured to drive the adsorption member 43 to move in the first horizontal direction to move the adsorption member 43 to the outside of any one of the storage units 11 of the container 10. The drive mechanism 30 is also configured to drive the adsorption member 43 to approach or move away from the current storage unit 11 to open or close the unit door 12 adsorbed by the adsorption member 43.

[0055] The container door opening device proposed in this application, through the cooperation of the drive mechanism 30 and the adsorption mechanism 40, realizes the automatic opening and closing of the unit door 12 of the storage unit 11 of the container 10, which has high work efficiency and saves manpower. At the same time, the adsorption component 43 of the adsorption mechanism 40 can be horizontally slidably installed on the base 41 through the sliding component 42. During the process of the drive mechanism 30 driving the adsorption component 43 to open or close the unit door 12, the adsorption component 43 can slide horizontally relative to the base 41 through the sliding component 42 to correct the movement trajectory of the adsorption component 43, so that the actual movement trajectory of the unit door 12 adsorbed by the adsorption component 43 matches the set trajectory of the adsorption component 43, thereby greatly reducing the probability of the adsorption component 43 falling off the unit door 12 and improving the success rate of the container door opening device.

[0056] Please refer to the figure.Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the adsorption mechanism 40 further includes an elastic reset component 44, which is configured to hold the sliding member 42 in a preset position on the base 41 when the adsorption member 43 does not adsorb the unit door 12.

[0057] As can be seen, by setting the elastic reset component 44, the adsorption component 43 is positioned in a preset position in front of the adsorption unit door 12, ensuring that the initial position of the adsorption component 43 adsorbing the next unit door 12 will not change.

[0058] In one embodiment, the elastic reset assembly 44 includes a guide shaft 440, a limiting member 441, and two elastic members 442. A receiving cavity 410 extending along a first horizontal direction is provided on the base 41. The guide shaft 440 is installed in the receiving cavity 410 extending along the first horizontal direction. The two elastic members 442 are sleeved on the guide shaft 440 at intervals along the first horizontal direction. The limiting member 441 is fixed on the sliding member 42 and extends into the receiving cavity 410 and is located between the two elastic members 442. The first ends of the two elastic members 442 respectively abut against the two sides of the limiting member 441 in the first horizontal direction, and the second ends of the two elastic members 442 respectively abut against the inner walls of the two ends of the receiving cavity 410 in the first horizontal direction.

[0059] Specifically, the elastic element 442 is a helical spring.

[0060] As can be seen, through the cooperation of the guide shaft 440, the limiting member 441 and the two elastic members 442, the sliding member 42 is held in the preset position of the base 41 by the elastic force of the two elastic members 442, providing an elastic reset assembly 44 with simple structure and stable and reliable operation; at the same time, by opening a receiving cavity 410 on the base 41 and integrating the elastic reset assembly 44 into the receiving cavity 410, the overall structure is compact and occupies little space.

[0061] In one embodiment, the limiting member 441 includes two parallel limiting plates 4410, with a gap between the two limiting plates 4410 for the guide shaft 440 to fit through, and the first ends of the two elastic members 442 respectively abut against the two limiting plates 4410 on both sides in the first horizontal direction.

[0062] It can be seen that by arranging two parallel limiting plates 4410 and fitting the guide shaft 440 through the gap between the two limiting plates 4410, the straightness of the sliding member 42 sliding in the first horizontal direction is ensured, and the stability and reliability of the horizontal sliding of the sliding member 42 are improved; by abutting the first ends of the two elastic members 442 against the two sides of the two limiting plates 4410 in the first horizontal direction, the uniformity and consistency of the elastic force applied by the two elastic members 442 to the limiting member 441 are ensured, which is beneficial to improve the resetting accuracy of the elastic resetting assembly 44.

[0063] As an implementation form, the accommodating cavity 410 is provided with a limiting groove 411 at each end in the first horizontal direction, and the two ends of the guide shaft 440 are embedded in the two limiting grooves 411, and the second ends of the two elastic members 442 abut against the notches of the two limiting grooves 411.

[0064] It can be seen that by arranging the limiting grooves 411 at each end of the accommodating cavity 410 in the first horizontal direction, and embedding the two ends of the guide shaft 440 in the two limiting grooves 411, the assembly of the guide shaft 440 is facilitated under the premise of ensuring the stability and reliability of the installation of the guide shaft 440.

[0065] As an implementation form, a sliding guide pair is arranged between the sliding member 42 and the base 41, the sliding guide pair includes a linear guide rail 45 and a sliding block 46, the linear guide rail 45 is fixed on the sliding member 42 in the first horizontal direction, and the sliding block 46 is fixedly connected with the base 41 and is slidably sleeved on the linear guide rail 45.

[0066] Specifically, two limiting blocks 420 are installed on the sliding member 42 at intervals, and the two limiting blocks 420 are located outside the two ends of the linear guide rail 45 in the length direction, so as to limit the stroke of the sliding block 46 on the linear guide rail 45.

[0067] Specifically, the cross section of the base 41 is T-shaped structure, the base 41 includes a base plate 412 and a connecting plate 413, the accommodating cavity 410 is arranged on the base plate 412, the connecting plate 413 is vertically fixed on the bottom surface of the base plate 412 and extends in the first horizontal direction, and the sliding block 46 is fixedly connected with the connecting plate 413 and is slidably sleeved on the linear guide rail 45.

[0068] Specifically, two sliding blocks 46 are arranged, and the two sliding blocks 46 are fixedly installed on the connecting plate 413 at intervals in the first horizontal direction, so as to improve the uniformity of the force received by the connecting plate 413.

[0069] Of course, the linear guide rail 45 and the sliding block 46 can also be assembled in the following form: the linear guide rail 45 is fixed on the base 41 in the first horizontal direction, and the sliding block 46 is fixedly connected with the sliding member 42 and is slidably sleeved on the linear guide rail 45.

[0070] It can be seen that by setting a sliding guide pair between the slider 42 and the base 41, the consistency and stability of the sliding direction of the slider 42 relative to the base 41 in the first horizontal direction are ensured.

[0071] In one embodiment, the adsorption mechanism 40 further includes a buffer plate 47 and a buffer assembly, wherein the buffer plate 47 can move along the second horizontal direction via the buffer assembly. Figure 1 The buffer assembly includes a guide rod and a spring 48. One end of the guide rod is fixedly connected to the buffer plate 47, and the other end of the guide rod is movably connected to the slide member 42. The spring 48 is sleeved on the guide rod, with the first end of the spring 48 abutting against the buffer plate 47 and the second end of the spring 48 abutting against the slide member 42.

[0072] As can be seen, by setting the buffer plate 47 and the buffer assembly, floating contact between the adsorption component 43 and the unit door 12 is achieved, so that after the adsorption component 43 contacts the unit door 12, it can adaptively adjust its own angle, ultimately ensuring that the adsorption surface of the adsorption component 43 can stick tightly to the unit door 12, thereby achieving the adsorption of the unit door 12; and it also avoids hard contact between the adsorption component 43 and the unit door 12, thus protecting the adsorption component 43 and the unit door 12.

[0073] In one embodiment, the adsorption member 43 is a suction cup, and a plurality of stop members 49 are installed on the buffer plate 47 around the suction cup. The stop members 49 extend along the second horizontal direction, and the adsorption end of the suction cup extends out of the stop members 49 in the second horizontal direction. The stop members 49 are configured to limit the deformation of the suction cup when it is in the adsorption unit door 12.

[0074] Specifically, four stoppers 49 are installed on the buffer plate 47 around the suction cup, and the stoppers of the four stoppers 49 are on the same vertical plane.

[0075] Specifically, the stop 49 is a stop bolt, and a mounting hole is provided on the buffer plate 47 to cooperate with the stop bolt. The tail end of the stop bolt passes through the mounting hole and is fixed to the buffer plate 47 by a nut.

[0076] As can be seen, by setting several stoppers 49, the deformation of the suction cup when it adsorbs the unit door 12 is limited. When the suction cup is squeezed to be flush with the stoppers 49, the stoppers 49 abut against the unit door 12, and the suction cup will not continue to shrink, thus avoiding damage to the suction cup.

[0077] In one embodiment, the adsorption element 43 is an accordion-type vacuum suction cup, and the adsorption end of the adsorption element 43 can rotate relative to the buffer plate 47.

[0078] It can be seen that by setting the suction accessory 43 as an accordion vacuum chuck, through the characteristics of the accordion vacuum chuck itself that can sway left and right, the moving track of the suction accessory 43 can be corrected, and the risk of the suction accessory 43 falling off the unit door 12 is further reduced.

[0079] Please refer to Figure 1 , Figure 2 and Figure 5 , as an embodiment, the driving mechanism 30 includes a first horizontal movement module 31, a first sliding seat 32, a second horizontal movement module 33, a second sliding seat 34, a rotary driving assembly 35 and a rotary seat 36. The first horizontal movement module 31 is installed on the rack 20. The first sliding seat 32 is slidingly installed on the rack 20 along the first horizontal direction and is connected with the driving end of the first horizontal movement module 31. The first horizontal movement module 31 is configured to drive the first sliding seat 32 to reciprocate along the first horizontal direction. The second horizontal movement module 33 is arranged on the first sliding seat 32. The second sliding seat 34 is slidingly installed on the first sliding seat 32 along the second horizontal direction. The driving end of the second horizontal movement module 33 is connected with the second sliding seat 34. The second horizontal movement module 33 is configured to drive the second sliding seat 34 to reciprocate along the second horizontal direction. The rotary driving assembly 35 is installed on the second sliding seat 34. The driving end of the rotary driving assembly 35 is connected with the rotary seat 36. The suction mechanism 40 is installed on the rotary seat 36. The rotary driving assembly 35 is configured to drive the rotary seat 36 to rotate, so as to drive the suction mechanism 40 to rotate relative to the current storage unit 11. The second horizontal movement module 33 and the rotary driving assembly 35 cooperate to drive the unit door 12 sucked by the suction mechanism 40 to rotate relative to the storage unit 11.

[0080] Specifically, the first horizontal movement module 31 can adopt various existing linear driving modules that can drive the first sliding seat 32 to slide on the rack 20 along the first horizontal direction. Preferably, the first horizontal movement module 31 adopts a horizontal movement module composed of a motor and a synchronous belt transmission assembly.

[0081] Specifically, the second horizontal movement module 33 can adopt various existing linear driving modules that can drive the second sliding seat 34 to slide on the first sliding seat 32 along the second horizontal direction. Preferably, the second horizontal movement module 33 adopts an electric cylinder.

[0082] Specifically, the rotary driving assembly 35 includes a rotary driving member, which is any one of a motor or a gas cylinder.

[0083] It can be seen that through the cooperation of the first horizontal movement module 31, the first sliding seat 32, the second horizontal movement module 33, and the second sliding seat 34, the unit door 12 is adsorbed by the suction accessory 43 and driven to rotate relative to the storage unit 11, so as to open or close the unit door 12. At the same time, through the setting of the rotary driving assembly 35 and the rotary seat 36, the suction accessory 43 always matches the opening angle of the unit door 12 relative to the storage unit 11 during the opening or closing process of the unit door 12, so as to ensure the smooth opening or closing of the unit door 12.

[0084] As an embodiment, the container door opening device comprises two suction mechanisms 40, each of which is provided with a lifting driving piece 50, and the two suction mechanisms 40 are arranged in mirror symmetry with the rotary seat 36 as the center and can be lifted relative to the rotary seat 36. The fixed end of the lifting driving piece 50 is installed on the rotary seat 36, the driving end of the lifting driving piece 50 is downward and connected to the corresponding suction mechanism 40, and the lifting driving piece 50 is configured to drive the corresponding suction mechanism 40 to lift.

[0085] Specifically, the lifting driving piece 50 is a gas cylinder.

[0086] It can be seen that the two suction mechanisms 40 realize double-sided adsorption and clamping of the unit door 12, which ensures that the unit door 12 can be rotated to a preset angle. Through the setting of the lifting driving piece 50, the suction mechanism 40 is lifted relative to the unit door 12 to avoid the unit door 12 during the opening or closing process of the unit door 12, and also realizes the opening of the next unit door 12 after the current unit door 12 is opened, without waiting for the completion of the containerization of the current storage unit 11. In addition, the unit door 12 of the storage unit 11 with the battery pack is closed after the current unit door 12 is opened.

[0087] Please refer to Figure 1 and Figure 2 Taking the opening of the unit door 12 of the corresponding storage unit 11 as an example, the door opening process of the container door opening device provided by the embodiment of the application is as follows:

[0088] S1, the driving mechanism 30 drives the suction mechanism 40 to move along the first horizontal direction to move the suction mechanism 40 to the outside of any one storage unit 11;

[0089] S2, the driving mechanism 30 drives the suction mechanism 40 to move along the second horizontal direction to the current storage unit 11, so as to adsorb the unit door 12 of the current storage unit 11 by the suction accessory 43;

[0090] S3, the driving mechanism 30 drives the adsorption mechanism 40 to move along the second horizontal direction away from the current storage unit 11, drives the unit door 12 adsorbed by the adsorption member 43 to rotate relative to the corresponding storage unit 11, and then opens the unit door 12 adsorbed by the adsorption member 43 by a preset angle. When the unit door 12 rotates relative to the corresponding storage unit 11, if the set movement track of the adsorption member 43 does not match the actual movement track of the unit door 12, the sliding piece 42 slides horizontally relative to the base 41 to correct the movement track of the adsorption member 43.

[0091] The container door opening device provided by the application has the following advantages:

[0092] 1) The sliding piece can slide horizontally relative to the base, and the movement track of the adsorption member is corrected during the opening or closing of the unit door, so that the actual movement track of the unit door adsorbed by the adsorption member matches the set track of the adsorption member, and the probability of the adsorption member falling off the unit door is greatly reduced;
