The loading device provided in this application includes a material placement section, a feeding section, a first drive mechanism, and a buffer mechanism. Operators place materials, such as corrugated cardboard covers, into the loading area. The feeding section transports the materials to the lifting area. A second drive mechanism drives the lifting plates, lifting the materials in the lifting area. The lifted materials can be directly moved to the packaging robot's gripper, or multiple sets of lifting plates can be used to buffer the lifted materials, awaiting the packaging robot's gripper. This facilitates automated battery cell packaging.

Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0039] After battery cells are manufactured, they need to be packaged. Currently, most packaging processes in the industry are done manually. One reason for this is the lack of suitable feeding devices to meet the continuous feeding requirements of automated packaging. For example, corrugated cardboard covers are needed for packaging. Automated packaging requires a robotic arm to grab and pack them. Currently, directly feeding the robotic arm by manual labor is inefficient, poses significant safety risks, and cannot meet the needs of continuous feeding in automated packaging.

[0040] Please see Figures 1 to 9In view of this, the present invention provides a feeding device, including a material placement section 100, a feeding section 200, a first driving mechanism 300, and a buffer mechanism 400. The material placement section 100 includes a feeding area 110 and a lifting area 120. The feeding section 200 is configured to cooperate with the material. The first driving mechanism 300 drives the feeding section 200 to reciprocate, so as to transport the material in the feeding area 110 to the lifting area 120. The buffer mechanism 400 includes a second driving mechanism 410 and multiple sets of lifting plates 420. The second driving mechanism 410 drives the multiple sets of lifting plates 420 to move, so as to sequentially lift the material in the lifting area 120.

[0041] The operator places materials into the loading area 110, and then the first drive mechanism 300 drives the feeding unit 200 to transport the materials from the loading area 110 to the lifting area 120. The second drive mechanism 410 then drives the lifting plate 420 to lift the materials in the lifting area 120, achieving spatial isolation between manual loading and robotic arm grasping. This avoids interference or collisions between manual loading and the robotic arm, reducing operator risks and effectively improving operational safety. By setting multiple sets of lifting plates 420, the operator continuously loads materials into the loading device during the intervals between robotic arm grasping operations. Multiple materials are buffered and lifted by multiple sets of lifting plates 420, which facilitates continuous grasping of materials by the robotic arm, improving loading efficiency and thus facilitating automatic packaging. The buffering mechanism 400 lifts the materials in the lifting area 120 upwards, making full use of the height dimension, occupying less space, and facilitating the integrated installation of the loading device and packaging device.

[0042] In one embodiment, the second drive mechanism 410 drives the lifting plate 420 to transport the material to the robotic arm's gripping area, facilitating gripping by the robotic arm, simplifying its movements, and improving packaging efficiency. The area from the lifting zone 120 to the robotic arm's gripping area is a buffer zone for materials, allowing for continuous gripping by the robotic arm.

[0043] Of course, as an alternative, the robotic arm can also directly reach into the material buffer area to grab materials to meet the material loading needs of the robotic arm.

[0044] Please see Figure 1 and Figure 2 In one embodiment, the feeding device includes a first limiting block 520, a second limiting block 530, and a guide limiting block 540, which respectively limit the position of the material in different areas.

[0045] The first limiting block 520 is disposed on both sides of the feeding area 110. The first limiting block 520 can be entirely located on both sides of the feeding area 110, or partially located on both sides of the feeding area 110 with the other part extending into both sides of the lifting area 120. The first limiting block 520 is used to restrict the position of the material in the feeding area 110. The second limiting block 530 is disposed on both sides of the lifting area 120. The second limiting block 530 can be entirely located on both sides of the lifting area 120, or partially located on both sides of the lifting area 120 with the other part extending into both sides of the feeding area 110. The second limiting block 530 is used to restrict the position of the material in the lifting area 120. The distance between the first limiting blocks 520 is greater than the distance between the second limiting blocks 530. The distance between the first limiting blocks 520 located on both sides of the feeding area 110 is relatively large, which makes it convenient for operators to place materials into the feeding area 110 and improves the placement efficiency of operators. The distance between the second limiting blocks 530 on both sides of the lifting area 120 is relatively small. For example, the distance between the second limiting blocks 530 is equal to or basically equal to the width of the material, so as to accurately position the material, facilitate the subsequent gripping by the robot arm, and improve the feeding accuracy.

[0046] In one embodiment, the positions of the first limiting block 520 and the second limiting block 530 can be selected in various ways. In a direction perpendicular to the direction from the feeding area 110 to the lifting area 120, the projections of the first limiting block 520 and the second limiting block 530 do not coincide. In other words, the first limiting block 520 and the second limiting block 530 are not set to coincide, which can reduce material usage, lower costs, and avoid waste.

[0047] Of course, as an option, the first limiting block 520 and the second limiting block 530 can also be partially overlapped to limit the position of the material in different areas.

[0048] Guide limit blocks 540 are disposed on both sides of the material placement section 100. One end of each guide limit block 540 is connected to the first limit block 520, and the other end is connected to the second limit block 530. The distance between the two guide limit blocks 540 gradually decreases from the feeding area 110 to the lifting area 120. When the feeding section 200 transports the material from the feeding area 110 to the lifting area 120, the guide limit blocks 540 play a guiding and correcting role, correcting and positioning the placed material during the material movement, so as to facilitate the buffer mechanism 400 to lift the material, improve the feeding accuracy, and meet the needs of automated packaging.

[0049] Please see Figure 2 In one embodiment, the feeding device further includes a positioning block 510, which is disposed on the side of the lifting area 120 away from the feeding area 110 to limit the travel of the material and limit and position the material.

[0050] Please see Figure 1 and Figure 3 In one embodiment, the feeding device includes a bottom frame 610 and side frames 620, with the side frames 620 disposed on both sides of the bottom frame 610. The bottom frame 610 and side frames 620 provide installation space for other components. The bottom frame 610 and side frames 620 can be a frame structure or a structure combining sheet metal and a frame structure.

[0051] The material placement section 100 is disposed on the bottom frame 610, and the first drive mechanism 300 is disposed on the frame. Preferably, the material placement section 100 is placed above the bottom frame 610, and the first drive mechanism 300 is disposed inside the frame, so as to isolate the operator from the first drive mechanism 300 through the material placement section 100, avoid the operator accidentally touching the first drive mechanism 300 and causing injury, and improve the safety of the feeding device operation.

[0052] In one embodiment, the material placement section 100 is a plate-like structure covering the bottom frame 610. The plate-like structure can be an electrical board, a stone slab, a metal plate, etc. The surface of the material placement section 100 is flat and smooth to facilitate the movement of materials on the surface of the material placement section 100 and reduce material damage.

[0053] Please see Figure 3 In one embodiment, the first driving mechanism 300 is disposed below the material placement section 100. The material placement section 100 is provided with a through groove 130, which penetrates the material placement section 100 and is arranged along the direction from the feeding area 110 to the lifting area 120. The feeding section 200 can at least partially penetrate upward through the through groove 130. The feeding section 200 moves along the through groove 130 to drive the material on the material placement section 100 from the feeding area 110 to the lifting area 120. By covering the first driving mechanism 300 with the material placement section 100, the safety of the operator when loading materials is improved, and the operator is prevented from accidentally touching the first driving mechanism 300.

[0054] In one embodiment, the first drive mechanism 300 includes a motor, a ball screw, a guide rail, and a slider. The feeding part 200 is fixed relative to the slider. The motor drives the ball screw to rotate so that the slider slides along the guide rail, thereby driving the feeding part 200 to move.

[0055] To improve the stability of material movement and prevent tilting during material movement, two feeding units 200 are provided, one on each side of the material placement unit 100. Two first driving mechanisms 300 are provided to drive the two feeding units 200 respectively.

[0056] When the feeding section 200 moves the material, the two feeding sections 200 need to move synchronously. Therefore, the two first drive mechanisms 300 need to move synchronously. In order to improve the synchronization of the two first drive mechanisms 300, the two first drive mechanisms 300 share a motor. The motor is connected to the two ball screws through couplings, right-angle steering gears, etc., so that one motor can synchronously drive the two ball screws to rotate, so that the two feeding sections 200 move synchronously. This can also save the number of motors and reduce the cost of the feeding device.

[0057] Of course, as some alternatives, the first drive mechanism 300 can also be other drive mechanisms, such as a combination of pneumatic telescopic rod, hydraulic telescopic rod, motor and transmission chain, etc., to drive the feeding part 200 to move linearly back and forth.

[0058] Please see Figure 5 and Figure 6 In one embodiment, the feeding unit 200 includes a connecting plate 210, a telescopic cylinder 220, and a pusher block 230. The connecting plate 210 is connected to the first driving mechanism 300, which drives the connecting plate 210 to reciprocate linearly. For example, when the first driving mechanism 300 includes a ball screw and a slider, the connecting plate 210 is fixed to the slider. The fixing method includes, but is not limited to, bolt connection and welding connection.

[0059] Please see Figure 6 A telescopic cylinder 220 is mounted on the connecting plate 210, and a push block 230 is installed on the push rod of the telescopic cylinder 220. The push block 230 is configured to abut against the material to drive the material to move. The telescopic cylinder 220 drives the push block 230 to move up and down, so that the push block 230 protrudes and retracts into the material placement section 100. After the feeding section 200 transports the material from the loading area 110 to the lifting area 120, the feeding section 200 needs to return to the loading area 110. The telescopic cylinder 220 drives the push block 230 to move downward until the top surface of the push block 230 is lower than the top surface of the material placement section 100, thereby avoiding interference between the feeding section 200 and the material when returning to its original position, preventing the material from being moved, and ensuring the accuracy of material loading. Meanwhile, as the pusher block 230 moves the material towards the lifting zone 120, the operator can continuously place materials into the feeding zone 110. After the pusher block 230 retracts downward, it moves to the inside of the material in the feeding zone 110, avoiding interference between the pusher block 230 and the material in the feeding zone 110, thus improving feeding efficiency.

[0060] Please see Figure 6 In one embodiment, the connecting plate 210 is an L-shaped plate, the slider is fixed to one side of the L-shaped plate, and the telescopic cylinder 220 is fixed to the other side of the L-shaped plate, thereby utilizing the side space of the first driving mechanism 300 to reduce the height of the first driving mechanism 300 and the feeding part 200 and improve the compactness of the feeding device.

[0061] Of course, as an alternative, the feeding section 200 may also include only the push block 230, which is connected to the first drive mechanism 300. When the feeding section 200 returns to its original position, the material is first carried away from the lifting area 120 by the buffer mechanism 400, and then the feeding section 200 returns to its original position to avoid interference with the material and ensure the accuracy of material feeding.

[0062] The buffer mechanism 400 is disposed on the side frame 620 and / or the bottom frame 610. The buffer mechanism 400 may be disposed on the side frame 620, or on the bottom frame 610, or partially disposed on the side frame 620 and partially disposed on the bottom frame 610.

[0063] Please see Figure 2 and Figure 7 In one embodiment, the second drive mechanism 410 includes a drive motor 411, a drive sprocket 412, a chain 413, and a driven sprocket 414. The drive motor 411 drives the drive sprocket 412 to rotate. The chain 413 is connected to the drive sprocket 412, and the drive sprocket 412 drives the chain 413 to move. The lifting plate 420 is disposed on the chain 413. The driven sprocket 414 is disposed at the upper end of the side frame 620, and the chain 413 is connected to the driven sprocket 414. The chain 413 spans the drive sprocket 412 and the driven sprocket 414. The drive motor 411 drives the drive sprocket 412 to rotate, thereby driving the chain 413 and the lifting plate 420 on the chain 413 to move. The lifting plate 420 can reciprocate or circulate.

[0064] Of course, as some alternatives, the second drive mechanism 410 can also be other drive mechanisms, such as a combination of a motor and a ball screw.

[0065] Please see Figure 2 and Figure 3 In one embodiment, at least three drive sprockets 412 are provided, for example, three, four, five or more. Lifting plates 420 are provided at the same positions on multiple drive sprockets 412. These lifting plates 420 at the same positions form a group of lifting plates 420. A group of lifting plates 420 provides support to multiple positions of the material, thereby ensuring the stability of material transportation. Preferably, four drive sprockets 412 are provided, and the material is generally square. The four lifting plates 420 provide support to the bottom of two sides of the material in pairs, thereby ensuring the stability of material movement.

[0066] To improve the synchronization of the movement of the drive sprocket 412 and prevent tilting during material lifting, the drive motor 411 synchronously drives multiple drive sprockets 412 to rotate via a transmission mechanism, thereby ensuring the synchronous rotation of the drive sprockets 412 and enabling the sprockets to move synchronously. The transmission mechanism may include structures such as couplings and direct steering gears to enable one drive motor 411 to drive multiple drive sprockets 412 to rotate simultaneously.

[0067] In one embodiment, the side support includes multiple hollow columns with openings facing the lifting area 120. Structures such as chains 413 are installed within the columns to shield and protect the chains 413. A lifting plate 420 extends through an opening into the lifting area 120 for lifting materials.

[0068] Please see Figure 7 In one embodiment, the cache mechanism 400 includes a lower base 430, a first mounting base 440, and a second mounting base 450.

[0069] The lower base 430 is fixed to the side frame 620, and the fixing method includes, but is not limited to, bolt connection and welding connection. The lower base 430 is provided with a first connecting hole, and the lower base 430 is used to connect the first mounting base 440 and the side frame 620.

[0070] Please see Figure 7 A first mounting base 440 is mounted on the lower base 430, and a drive sprocket 412 is mounted on the first mounting base 440. The first mounting base 440 has a second connecting hole 441, which is an oblong hole. The first mounting base 440 and the second mounting base 450 are fixed relative to each other by a connector, such as a bolt passing through the first and second connecting holes 441. At least one of the first and second connecting holes 441 is an oblong hole, allowing for adjustment of the relative position of the first mounting base 440 and the second mounting base 450. The length direction of the oblong hole is consistent with the direction of the opening of the hollow column, used to adjust the distance between the drive sprocket 412 and the lifting area 120, thereby adjusting the position between the lifting plate 420 and the lifting area 120 and improving the accuracy of material lifting by the lifting plate 420.

[0071] Please see Figure 4 and Figure 7The second mounting base 450 is disposed on the upper part of the side frame 620. The driven sprocket 414 is mounted on the second mounting base 450 through the third connecting hole 451. The second mounting base 450 is provided with a third connecting hole 451, which is an oblong hole. The length direction of the third connecting hole 451 is the same as the opening direction of the hollow column, so as to adjust the distance between the driven sprocket 414 and the lifting area 120. The driven sprocket 414 and the driving sprocket 412 cooperate to adjust the distance between the lifting plate 420 and the lifting area 120.

[0072] Please see Figure 7 and Figure 8 In one embodiment, both ends of the rotating shaft of the driven sprocket 414 are provided with adjusting rods 4141. The adjusting rods 4141 pass through the third connecting hole 451. The adjusting rods 4141 do not rotate within the third connecting hole 451. For example, the upper and lower sides of the adjusting rods 4141 are both planes that mate with the third connecting hole 451, so that the upper and lower sides of the adjusting rods 4141 abut or substantially abut with the third connecting hole 451, thereby restricting the relative rotation between the adjusting rods 4141 and the third connecting hole 451.

[0073] Please see Figure 7 and Figure 8 A first adjusting screw 452 is provided on the second mounting base 450. The first adjusting screw 452 is rotatably mounted on the side of the second mounting base 450, and the axial direction of the first adjusting screw 452 is consistent with the length direction of the third connecting hole 451. An adjusting rod 4141 is provided with a first threaded hole that is threaded to the first adjusting screw 452. By rotating the first adjusting screw 452, the distance by which the first adjusting screw 452 is screwed into the first threaded hole changes, thereby adjusting the position of the adjusting rod 4141 in the third connecting hole 451. This facilitates the adjustment of the position between the driven sprocket 414 and the lifting area 120, and thus the adjustment of the position between the lifting plate 420 and the lifting area 120.

[0074] Please see Figure 4In one embodiment, an upper base 622 is fixedly mounted on the side frame 620. A second adjusting screw 6221 is rotatably mounted on the upper base 622. The axial direction of the second adjusting screw 6221 is consistent with the lifting direction of the material; in other words, the axial direction of the second adjusting screw 6221 is consistent with the movement direction of the chain 413. A second mounting base 450 is provided with a second threaded hole that mates with the second adjusting screw 6221. The second mounting base 450 is fixed to the upper base 622 by being threadedly connected to the second adjusting screw 6221, thereby fixing the second mounting base 450 to the side frame 620. By rotating the second adjusting screw 6221, the distance by which the second adjusting screw 6221 is screwed into the second threaded hole changes, thereby adjusting the relative position of the second mounting base 450 and the upper base 622. This causes the driven sprocket 414 to move closer to or further away from the driving sprocket 412, thus adjusting the tension of the chain 413.

[0075] In one embodiment, one surface of the second mounting base 450 abuts against one surface of the upper base 622, so that the connection between the second mounting base 450 and the upper base 622 is more stable, reducing the shaking of the second mounting base 450 and improving the stability of the movement of the lifting plate 420.

[0076] In one embodiment, the lifting plate 420 is an L-shaped plate, one plate is connected to the chain 413, and the other plate is used to support the material and lift the material.

[0077] In other embodiments, the lifting plate 420 may also be a structure of other shapes, such as a straight plate, a block, etc.

[0078] Please see Figure 4 In one embodiment, the side frame 620 is provided with a sliding groove 621. For example, when the side frame 620 includes multiple hollow columns, the sliding groove 621 is provided at the opening of the hollow column. The sliding groove 621 can be directly opened on the side frame 620, or it can be formed by other structures fixed on the side frame 620.

[0079] Please see Figure 4 At least two rollers 421 are respectively provided on both sides of the lifting plate 420. In other words, at least two rollers 421 are provided on one side of the lifting plate 420, and at least four rollers 421 are provided on each lifting plate 420. The rollers 421 roll along the slide groove 621. The two rollers 421 on one side are arranged vertically. When the lifting plate 420 drives the material to move, it limits the lifting plate 420 to prevent the lifting plate 420 from tilting due to force, thereby improving the stability of the lifting plate 420 and preventing the material from tilting or overturning.

[0080] Please see Figure 9In one embodiment, a baffle plate 422 is provided on the side of the lifting plate 420. The baffle plate 422 is inclined towards the chain 413 in a direction outward from the lifting plate 420. In other words, the baffle plate 422 is inclined from the center of the lifting plate 420 towards the chain 413 in a direction outward from the lifting plate 420. The baffle plate 422 can block the chain 413 and prevent the chain 413 from interfering with the material. The inclined arrangement of the baffle plate 422 guides and corrects the material when it interferes with the baffle plate 422, thereby preventing the material from extending into the chain 413 and effectively preventing damage to the material and jamming of the chain 413.

[0081] Please see Figure 1 In one embodiment, the feeding device includes a detection unit 720, which is disposed on the side of the feeding area 110 to detect whether there is material on the feeding area 110, thereby facilitating the control of the start and stop of the first drive mechanism 300.

[0082] The detection unit 720 can be photoelectric detection or infrared detection, etc., to detect whether there is material on the feeding area 110.

[0083] Of course, as some alternatives, the detection unit 720 can also be set at the bottom or top of the feeding area 110. For example, the detection unit 720 can be a pressure detector to determine whether there is material in the feeding area 110.

[0084] Furthermore, the inspection unit 720 can also determine whether the material is placed upside down, ensuring that the material is placed correctly and facilitating subsequent gripping by the robotic arm.

[0085] Please see Figure 1 In one embodiment, the feeding device includes a protective shell 710, which is disposed on the side of the feeding area 110 and has an opening on the side facing the feeding area 110. The detection unit 720 is disposed inside the protective shell 710. The protective shell 710 protects the detection unit 720, reducing the risk of damage to the detection unit 720 and increasing the average service life of the detection unit 720.

[0086] Please see Figure 1 In one embodiment, the feeding device includes a button box 730, which is located on the side of the feeding area 110. The button box 730 contains a start button and an emergency stop button. When an operator places material into the feeding area 110, the start button triggers the feeding request. The feeding unit 200 transports the material to the lifting area 120, and then the second drive mechanism 410 drives the lifting plate 420 to lift the material, awaiting grabbing by the robotic arm. The emergency stop button is used for emergency stopping in special circumstances such as malfunctions to improve safety.

[0087] Furthermore, there are two start buttons. When both start buttons are pressed at the same time, the feeding device starts feeding. When the two start buttons are not pressed at the same time, the feeding device does not start feeding. That is, the operator needs to press the two start buttons with both hands respectively to improve the safety of the feeding device.

[0088] Please see Figure 1 In one embodiment, the feeding device includes a protective plate 800, which is disposed on the side of the lifting area 120. Preferably, protective plates 800 are disposed on all four sides of the lifting area 120. The protective plates 800 on the side of the lifting area 120 facing the feeding area 110 are disposed above and on both sides of the material placement part 100. The side of the protective plate 800 facing the feeding area 110 has an opening for accommodating material passage, allowing material to move from the feeding area 110 into the lifting area 120. A buffer zone is located within the space enclosed by the protective plates 800 to isolate the operator from the buffer zone and from the lifting area 120, thus protecting the operator and reducing the risk of injury.

[0089] This utility model's feeding device integrates feeding and buffering functions, allowing operators to continuously feed materials, improving feeding efficiency and facilitating automated packaging. The first limiting block 520, the second limiting block 530, the guide limiting block 540, and the positioning block 510 position the materials, improving positioning accuracy and increasing packaging success rate. The up-and-down movement of the pusher block 230 facilitates continuous feeding by the operator, further enhancing feeding efficiency. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus possessing high utilization value and practical significance.

[0090] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
