[0052] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0053] During the production and assembly process of the battery device, it is necessary to perform glue sticking operations on the side of the battery cell; that is, after using a robot to grab the glue strip, the glue strip is pasted on the side of the battery cell along a preset direction; illustratively, the length direction of at least one glue strip is pasted in the horizontal direction, and at the same time, the length direction of at least one glue strip is pasted in the vertical direction. However, multiple glue strips need to be pasted on the side of each battery cell, and the pasting directions of the multiple glue strips are not exactly the same. In the related art, it is necessary to set up multiple robots to grab the glue strips respectively and paste them at designated positions according to the preset pasting direction to realize the layout of the glue strips on the side of the battery cell. However, when multiple robots are used, the multiple robots need to grab, identify, transport and glue the glue strips respectively, which results in low glue sticking efficiency.

[0054] Based on the above considerations, in order to solve the problem of low efficiency caused by the use of multiple manipulators to separately glue multiple strips of glue in the related technology, a glue sticking equipment is designed. By setting a stacking mechanism in the glue sticking equipment, the driving mechanism can drive the moving parts in the stacking mechanism to move to a stacking state, so that at least part of the multiple moving parts are arranged around the rotating shaft, so that the material tray on the moving part is also synchronously arranged around the rotating shaft. As a result, the strips of glue arranged on the material tray can be stacked around the rotating shaft. At this time, a grasping mechanism can be used to synchronously act on multiple material trays around the rotating shaft, and the strips of glue in the multiple material trays can be synchronously grasped and glue sticking operations can be performed, thereby effectively improving the glue sticking efficiency.

[0071] The end cap 21 refers to a component that covers the opening of the shell 22 to isolate the internal environment of the battery cell 20 from the external environment. Without limitation, the shape of the end cap 21 can be adapted to the shape of the shell 22 to match the shell 22. Optionally, the end cap 21 can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap 21 is not easily deformed when squeezed and collided, so that the battery cell 20 can have a higher structural strength and improved reliability.

[0074] According to some embodiments of the present application, referring to Figure 3 , Figure 5 and Figure 8 The embodiment of the present application provides a glue sticking device 1000, including a driving mechanism 200, a stacking mechanism 300 and a grabbing mechanism 400; the stacking mechanism 300 includes a rotating structure 310 and a plurality of moving parts 320, the rotating structure 310 is provided with a rotating shaft 311, and the rotating structure 310 is configured to be able to rotate around the rotating shaft 311; adjacent moving parts 320 are rotatably connected, and at least two of the plurality of moving parts 320 are respectively provided with a material tray 330; the rotating structure 310 is connected to the first moving part 320 of the plurality of moving parts 320, and the driving mechanism The drive is connected to the last moving member 320 of the multiple moving members 320; wherein the driving mechanism 200 is used to drive the multiple moving members 320 to move to the initial state, so that the multiple moving members 320 are arranged in sequence along the driving direction S of the driving mechanism 200; or, the driving mechanism 200 is used to drive the multiple moving members 320 to move to a stacked state, so that at least part of the moving members 320 moves around the rotating shaft 311, and the multiple material trays 330 synchronously revolve around the rotating shaft 311; in the stacked state, the grasping mechanism 400 is configured to be able to act on the multiple material trays 330 synchronously.

[0075] The driving mechanism 200 is used to provide driving force to achieve the purpose of driving the multiple moving members 320 to move. Optionally, the driving source of the driving mechanism 200 can be but is not limited to a cylinder, a hydraulic cylinder, a motor, etc.

[0076] Exemplarily, in some embodiments, the driving source of the driving mechanism 200 can be a hydraulic cylinder, and the driving mechanism 200 can also include a slider, the output end of the hydraulic cylinder is connected to the slider, and the slider is connected to the moving part 320; in this way, the slider is controlled by the extension and contraction of the piston of the hydraulic cylinder to drive the moving part 320 to move back and forth.

[0077] Alternatively, in some other embodiments, the driving source of the driving mechanism 200 may be a motor, and the driving mechanism 200 further includes a roller and a slider meshingly connected to the roller. The output end of the motor drives the roller, and the slider is connected to the moving member 320; thus, the roller is driven to rotate by the motor, so that the slider can move along the axial direction of the roller and drive the moving member 320 to reciprocate.

[0078] It should be understood that the driving mechanism 200 can provide power through a variety of driving sources and drive the moving part 320 to move back and forth through a variety of transmission structures, which are not listed one by one in this embodiment. It is only necessary to realize that the driving mechanism 200 drives the moving part 320 to move along the driving direction S.

[0079] The stacking mechanism 300 refers to a mechanism that can adjust the direction of the rubber strips and stack the rubber strips. The stacking mechanism 300 includes a rotating structure 310 and a plurality of moving parts 320; wherein the rotating structure 310 refers to a structure that can realize rotation, for example, the rotating structure 310 can be, but is not limited to, a turntable, a rotating block, a rotating rod and other structures. The rotating structure 310 has a rotating shaft 311, so that the rotating structure 310 can rotate around the rotating shaft 311. Among them, the force used by the rotating structure 310 to realize the rotation can be, but is not limited to, provided by the connected moving parts 320 applying a force, or provided by a driving structure such as a motor driving the connecting rotating shaft 311, or the driving mechanism 200 synchronously drives the connecting rotating shaft 311, etc. The rotating structure 310 can be assembled on one side of the driving mechanism 200 through a bearing structure such as a support, a bracket, etc., and the rotating shaft 311 is rotated and set on the above-mentioned bearing structure so that the rotating shaft 311 can drive the rotating structure 310 to rotate.

[0080] It is understandable that the plurality of moving members 320 may be two, three or more than three, and adjacent moving members 320 are rotatably connected (e.g., hinged, etc.). The moving members 320 include but are not limited to block structures of various configurations, such as rectangular blocks, spherical blocks, arc-shaped blocks, etc.

[0081] Exemplarily, in some embodiments, the moving member 320 may include a first moving block 321 and a second moving block 322 stacked on the first moving block 321, wherein the first moving block 321 is convexly provided at one end along the driving direction S of the driving mechanism 200 to form a first connecting portion 321a, and the second moving block 322 is convexly provided at the other end opposite to the driving direction S of the driving mechanism 200 to form a second connecting portion 322a; among the multiple moving members 320, the front second connecting portion 322a of two adjacent moving members 320 is hinged to the rear first connecting portion 321a, and the first connecting portion 321a of the first one of the multiple moving members 320 is fixedly connected to the rotating structure 310, and the second connecting portion 322a of the last one of the multiple moving members 320 is fixedly connected to the driving mechanism 200; in this way, the multiple moving members 320 can move linearly along the driving direction S of the driving mechanism 200, or, the multiple moving members 320 can rotate around the rotating shaft 311 to form a ring under the action of the rotating structure 310.

[0082] At least two of the multiple moving parts 320 are respectively provided with a material tray 330; optionally, the number of material trays 330 may be consistent with the number of moving parts 320, that is, each moving part 320 is provided with a material tray 330; or, the number of material trays 330 may be less than the number of moving parts 320, that is, some of the multiple moving parts 320 are provided with material trays 330; illustratively, a material tray 330 may be provided for every moving part 320, so as to better meet the length layout requirements of the material trays 330.

[0083] The tray 330 may be, but is not limited to, a supporting structure such as a tray or a support block; in some embodiments, the tray 330 may be a rectangular block structure, and in the initial state, the length direction of the tray 330 may be arranged along the driving direction S of the driving mechanism 200; in this way, the loading operation of the tray 330 can be facilitated, and the length direction of the strip rubber can be set and loaded along the length direction parallel to the tray 330. In addition, when the moving member 320 moves to a stacked state of rotating around the rotating shaft 311 to form a ring, multiple trays 330 can also rotate around the rotating shaft 311 to form a ring, and the length directions of multiple trays 330 can be rotated and adjusted to the corresponding direction according to the requirements. Exemplarily, when the number of trays 330 is three, the three trays 330 can be rotated to form a state perpendicular to each other, that is, the two trays 330 spaced apart are in a parallel state to meet the layout requirements of the strip rubber.

[0084] It should be understood that the above-mentioned initial state refers to the state when multiple moving parts 320 are arranged in sequence along the driving direction S of the driving mechanism 200 and are not orbiting around the rotating shaft 311; in the initial state, multiple material trays 330 are arranged in sequence along the driving direction S of the driving mechanism 200, so as to facilitate the loading operation of multiple material trays 330.

[0085] The above-mentioned stacking state refers to a state in which at least some of the multiple moving parts 320 rotate around the rotating shaft 311 and surround the rotating shaft 311; in the stacking state, the moving parts 320 with the material tray 330 are arranged around the rotating shaft 311, so that the multiple material trays 330 are also arranged around the rotating shaft 311, so as to facilitate the subsequent grabbing operation of the rubber strip by the grabbing mechanism 400.

[0086] The gripping mechanism 400 is used to perform material picking and gluing operations, that is, the gripping mechanism 400 can synchronously grab the strips of glue contained in the multiple material trays 330 in a stacked state, and synchronously stick the grabbed strips of glue on the side of the corresponding battery cell 20. Optionally, the gripping mechanism 400 may include a suction cup structure and a driving structure, the suction cup structure is used to absorb the strips of glue to achieve the gripping operation; the driving structure is used to drive the suction cup structure to move to the material tray 330 or to the side of the battery cell 20. Exemplarily, in some embodiments, the gripping mechanism 400 may be a multi-axis or multi-degree-of-freedom gripping mechanism; Exemplarily, in some embodiments, the gripping mechanism 400 may use a spider robot arm, and the end of the spider robot arm is provided with a suction cup, and the spider robot arm is used to drive the suction cup to absorb the strips of glue on the material tray 330 to achieve the gripping action, and then drive the suction cup adsorbed with the strips of glue to move to the side of the battery cell 20 to perform the gluing action.

[0087] The glue sticking device 1000 provided in the embodiment of the present application utilizes the driving mechanism 200 to drive multiple moving parts 320 to move. When moving to the initial state, the multiple moving parts 320 are arranged in sequence along the driving direction S of the driving mechanism 200 to facilitate loading of the material tray 330 on the moving part 320. When moving to the stacking state, at least part of the moving parts 320 can be arranged around the rotating shaft 311, so that the multiple material trays 330 synchronously surround the rotating shaft 311 to form a stacking state; in this way, the grasping mechanism 400 can synchronously act on the multiple material trays 330 in the stacking state and grasp the strips of glue in the multiple material trays 330, so as to synchronously move the multiple strips of glue and perform glue sticking operations; therefore, the glue sticking device 1000 of the present application can utilize a grasping mechanism 400 to synchronously grasp and glue stick multiple strips of glue, thereby effectively improving the glue sticking efficiency.

[0088] Please refer to Figure 5 and Figure 8 In some embodiments, a transmission gear 311 a is disposed on the rotating shaft 311 , and the output end of the driving mechanism 200 is meshedly connected with the transmission gear 311 a .

[0089] In the present embodiment, by arranging the transmission gear 311a on the rotating shaft 311, and meshing the output end of the driving mechanism 200 with the transmission gear 311a, in this way, when the driving mechanism 200 drives the moving member 320 to move, the driving mechanism 200 can also synchronously drive the transmission gear 311a to rotate, so that the transmission gear 311a drives the rotating shaft 311 and the rotating structure 310 to rotate synchronously. In this way, the rotating structure 310 can act on the first moving member 320 of a plurality of moving members 320, and the driving mechanism 200 can act on the last moving member 320 of a plurality of moving members 320 at the same time, so that the head and tail of the plurality of moving members 320 are all driven and moved.

[0090] With such arrangement, a plurality of movable members 320 connected in rotation in sequence can move when the first movable member 320 and the last movable member 320 are acted upon by force at the same time, thereby effectively improving the movement stability of the movable member 320 and further improving the reliability of the stacking mechanism 300 .

[0091] Please refer to Figure 5 , Figure 7 and Figure 8 In some embodiments, the driving mechanism 200 includes a driving member 210, a sliding member 220 and a fixed seat 230, a slide rail 231 is provided on the fixed seat 230, the sliding member 220 is slidably connected to the slide rail 231, and the driving member 210 drives the sliding member 220; the last moving member 320 of the multiple moving members 320 is connected to the sliding member 220.

[0092] The driving member 210 is used to provide a power source; the driving member 210 may be, but is not limited to, a driving cylinder, a driving hydraulic cylinder, etc. The driving member 210 is fixed relative to the sliding member 220, for example, fixedly arranged on the fixing seat 230; thus, the driving member 210 can drive the sliding member 220 to move.

[0093] The sliding member 220 includes but is not limited to a sliding block, a sliding plate, a sliding bracket and other structures; the sliding member 220 is slidably connected to the slide rail 231 of the fixed seat 230; optionally, a slide groove can be provided on the sliding member 220, and the sliding of the sliding member 220 along the slide rail 231 is achieved by the sliding cooperation between the slide rail 231 and the slide groove. The sliding member 220 is connected to the moving member 320, and the driving member 210 drives the sliding member 220, so that the driving member 210 can drive the sliding member 220 to move and drive the moving member 320 to move synchronously.

[0094] The fixed seat 230 is used to support the sliding member 220; optionally, the fixed seat 230 can be but is not limited to a support, a bracket, a fixed block or other structures; in some embodiments, the gluing equipment 1000 can also include a main structure such as a machine tool or a frame, and the fixed seat 230 can be fixedly installed on the machine tool or the frame by fasteners, and the rotating structure 310 and the rotating structure can be rotatably set on the machine tool or the frame, and the grasping mechanism 400 can also be assembled on the machine tool or the frame to realize the gluing operation.

[0095] In this configuration, the driving member 210 drives the sliding member 220 to move along the slide rail 231 , so that the sliding member 220 can drive the moving member 320 to move to the stacking state or the initial state.

[0096] Please refer to Figure 5 , Figure 7 and Figure 8 In some embodiments, a rack structure 220 a is disposed on the sliding member 220 , and the rack structure 220 a is meshedly connected to the transmission gear 311 a .

[0097] In the present embodiment, a rack structure 220a is provided on the sliding member 220, and the rack structure 220a is meshedly connected to the transmission gear 311a; in this way, when the driving member 210 drives the sliding member 220 to move and drives the moving member 320 to move, the sliding member 220 synchronously drives the transmission gear 311a and the rotating shaft 311 to rotate through the rack structure 220a, so that the rotating structure 310 rotates synchronously. Thus, the rotating structure 310 of the first moving member 320 connected to the plurality of moving members 320 can rotate and act on the first moving member 320, and the sliding member 220 can act on the last moving member 320 of the plurality of moving members 320, so that the plurality of moving members 320 move when both the head and the tail have an acting force.

[0098] With such arrangement, when the driving member 210 drives the sliding member 220 to drive the moving member 320 to move, the sliding member 220 drives the rotating shaft 311 and the rotating structure 310 to rotate synchronously through the rack structure 220a and the meshing transmission gear 311a, thereby making the moving member 320 more consistent with the rotating structure 310, so as to improve the reliability of the stacking structure, and further improve the stability of the operation of the gluing equipment 1000.

[0099] Please refer to Figure 5 , Figure 7 and Figure 8 In some embodiments, a limit assembly 232 is provided on the fixed seat 230, and the limit assembly 232 includes a limit sensor 2321 and / or a limit structure 2322, and the limit sensor 2321 and / or the limit structure 2322 are arranged on the moving path of the sliding member 220; the limit sensor 2321 is electrically connected to the driving member 210.

[0100] Optionally, the limiting assembly 232 may be provided at one end of the sliding block along the driving direction S, or the limiting assembly 232 may be provided at both opposite ends of the sliding block along the driving direction S.

[0101] In some embodiments, the limit assembly 232 may include only the limit sensor 2321 or only the limit structure 2322; or, in other embodiments, the limit structure 2322 may include both the limit sensor 2321 and the limit structure 2322. The limit sensor 2321 and / or the limit structure 2322 may be fixedly mounted on the fixing seat 230 by means of a mounting block, a mounting bracket or other mounting structures.

[0102] The limit sensor 2321 refers to a sensor for detecting and limiting the moving range of the sliding member 220 along the driving direction S of the driving mechanism 200; when the limit sensor 2321 senses that the sliding member 220 moves to a preset position, the limit sensor 2321 sends an electrical signal to the driving member 210, so that the driving member 210 drives the sliding member 220 to stop, thereby reducing the probability of excessive movement of the sliding member 220. Optionally, the limit sensor 2321 can be, but is not limited to, a limit switch, a photoelectric sensor, a proximity sensor, etc.

[0103] The limiting structure 2322 refers to a structure for hard limiting the sliding member 220 ; the limiting structure 2322 can be set at the maximum movement range of the sliding member 220 along the driving direction S of the driving mechanism 200 to reduce the probability of excessive movement of the sliding member 220 .

[0104] In this configuration, the movement range of the sliding member 220 is limited by using the limiting assembly 232, so as to reduce the probability that the sliding member 220 moves excessively and causes damage to the moving member 320 and the rotating structure 310.

[0105] Please refer to Figure 8 and Fig. 9 In some embodiments, the number of the material trays 330 is at least three, and in the stacked state, adjacent material trays 330 are arranged to intersect.

[0106] Optionally, the number of the trays 330 may be three, four, or any number greater than four. For example, taking three trays 330 as an example, in a stacked state, the grabbing mechanism 400 may act on the three trays 330 at the same time and grab the adhesive strips on the three trays 330 at the same time, and affix the three adhesive strips to the sides of the battery cell 20.

[0107] In the stacked state, the adjacent material trays 330 are arranged to intersect each other; it should be understood that in the initial state, the plurality of moving members 320 are sequentially arranged along the driving direction S, so that the plurality of material trays 330 located on the moving members 320 are also sequentially arranged to form a straight line. When the moving members 320 move to the stacked state, the plurality of material trays 330 are arranged around the rotating shaft 311, so that the plurality of material trays 330 rotate from being sequentially arranged to form a straight line to being sequentially intersecting.

[0108] Optionally, adjacent trays 330 may intersect to form an acute angle, a leg or an obtuse angle; illustratively, taking three trays 330 as an example, any two adjacent trays 330 in the three trays 330 may intersect to form a right angle, that is, two adjacent trays 330 are arranged perpendicularly to each other, so that two interval trays 330 in the three trays 330 are parallel; thus, the strips of rubber in the three trays 330 are also arranged to form a state where two adjacent trays 330 are perpendicular to each other, such as Fig. 9 As shown; the grabbing mechanism 400 can grab the three strips of glue in the three trays 330 according to the current layout state and stick them on the side of the battery cell 20.

[0109] In this way, the at least three adhesive strips placed on the at least three material trays 330 can be arranged to intersect in sequence, so that the grasping mechanism 400 can directly grasp the at least three adhesive strips to be attached to the side surface of the battery cell 20 .

[0110] Please refer to Figure 5 and Figure 8 In some embodiments, the rotating structure 310 is a turntable 310a, the center of the turntable 310a is connected to the rotation shaft 311; the first moving member 320 of the plurality of moving members 320 is disposed on the surface of the turntable 310a.

[0111] In this embodiment, the rotating structure 310 may be a rotating disk 310 a , whereby the rotating disk 310 a may rotate around a rotating shaft 311 , that is, rotate around its own center.

[0112] The first moving member 320 among the plurality of moving members 320 is disposed on the surface of the turntable 310a; optionally, the first moving member 320 among the plurality of moving members 320 can be fixedly connected to the surface of the turntable 310a by fastener connection, welding, clamping, etc.

[0113] With such an arrangement, at least part of the multiple moving parts 320 can move to the surface of the turntable 310a and surround the rotating shaft 311, so that the multiple material trays 330 are simultaneously located above the turntable 310a and surround the rotating shaft 311, thereby facilitating the grasping mechanism 400 to synchronously grasp the strips of glue on the multiple material trays 330 and perform the gluing operation.

[0114] Please refer to Figure 5 , Figure 7and Figure 8 In some embodiments, a support structure 220 b is provided on the sliding member 220 , and in an initial state, the support structure 220 b is used to support the moving member 320 .

[0115] It is understandable that the support structure 220b may be, but is not limited to, a support block, a support frame, a support column, etc., which are used to form a support structure. The support structure 220b may be fixedly disposed on the sliding member 220 by fastener connection, welding, clamping, etc.

[0116] It should be understood that when the first moving member 320 of the multiple moving members 320 is connected to the surface of the turntable 310a, and the last moving member 320 of the multiple moving members 320 is connected to the sliding member 220, part of the multiple moving members 320 will form a suspended state, that is, part of the moving members 320 is suspended without support.

[0117] By setting a supporting structure 220b on the sliding member 220, in an initial state, the first moving member 320 of the multiple moving members 320 is connected to the surface of the turntable 310a, and the multiple moving members 320 are arranged in sequence along the driving direction S of the driving mechanism 200. At this time, the supporting structure 220b can be located under at least part of the multiple moving members 320, thereby being able to support at least part of the moving members 320.

[0118] Exemplarily, in some embodiments, the support structure 220b can adopt an elongated support block, which is fixedly mounted on the sliding member 220 by fasteners, and in the initial state, the support block can support the bottom of the first moving member 320 of the multiple moving members 320 located outside the turntable 310a, and the support block is arranged along the driving direction S of the driving mechanism 200 and can support all the moving members 320; when the driving mechanism 200 drives the sliding member 220 to move along the driving direction S, the support block can move synchronously, and the moving members 320 can move forward in sequence along the driving direction S to the top of the turntable 310a and rotate around the rotating shaft 311, that is, the moving member 320 continues to be supported by the turntable 310a after breaking away from the support of the support block.

[0119] With such arrangement, in the initial state, the support structure 220b can support the moving part 320 to improve the stability of the moving part 320 in the initial state and the stability of the moving part 320 during the movement from the moving part 320 to the stacking state, thereby improving the reliability of the gluing equipment 1000.

[0120] Please refer to Figures 3 to 5 and Figure 8In some embodiments, the glue laminating device 1000 further includes a loading component 500 , and the loading component 500 has a feeding end 501 ; the number of the loading component 500 is one, and in an initial state, the feeding end 501 faces one of the material trays 330 .

[0121] The feeding assembly 500 is used to feed the rubber strip. Optionally, the feeding assembly 500 may be a feeding feeder, a belt conveyor, etc. For example, taking the feeding feeder as an example, the feeding feeder may be a belt feeder, which may be arranged beside the sliding member 220, and the belt feeder is used to transfer the rubber strip to the material tray 330 to achieve the feeding operation.

[0122] Among them, in the initial state, the feeding end 501 is facing one of the material trays 330; thus, the driving member 210 can be used to drive the moving member 320 to move along the driving direction S, so that other material trays 330 can be moved to the feeding end 501, and the loading assembly 500 performs loading operations on multiple material trays 330 respectively through the feeding end 501.

[0123] With such an arrangement, a loading assembly 500 can be used to load multiple material trays 330 respectively, and the adhesive strips are delivered to the material trays 330 through the feeding end 501. The driving member 210 then drives the multiple material trays 330 to rotate above the turntable 310a and around the rotating shaft 311 to facilitate the material picking and adhesive application operations of the grabbing mechanism 400.

[0124] Please refer to Figures 3 to 5 and Figure 8 In some embodiments, the glue laminating device 1000 further includes a loading assembly 500, and the loading assembly 500 has a feeding end 501; the number of the loading assemblies 500 is at least two ( Figure 2 Only one loading assembly 500 is shown. When there are multiple loading assemblies 500, the multiple loading assemblies 500 are arranged in sequence along the driving direction S). In the initial state, each feeding end 501 faces the corresponding material tray 330.

[0125] In this embodiment, the number of the loading components 500 is at least two, for example, two, three or more. It should be understood that the number of the loading components 500 can be consistent with the number of the material trays 330, so that each loading component 500 performs a loading operation on the corresponding material tray 330 through its respective feeding end 501; or, the number of the loading components 500 can be less than the material trays 330, so that at least one loading component 500 can be used to load two or more material trays 330.

[0126] With such an arrangement, multiple loading components 500 can be used to synchronously load multiple material trays 330 . Multiple loading components 500 can load different materials at the same time, for example, load strips of rubber of different specifications at the same time, thereby meeting the loading requirements of different materials.

[0127] Please refer to Figures 3 to 6 In some embodiments, a limiting member 331 is provided on the material tray 330 .

[0128] Optionally, the limiting member 331 may be, but is not limited to, a limiting structure 2322 such as a limiting block, a limiting column, a limiting rod, or a limiting convex portion; the limiting member 331 may be fixedly connected to the tray 330 by plugging, clamping, or fastener connection. When the loading assembly 500 delivers the strip rubber to the tray 330 through the feeding end 501, the limiting member 331 can limit the movement range of the strip rubber so that the strip rubber is disposed against the limiting member 331.

[0129] With such arrangement, when the feeding end 501 of the loading component 500 feeds the material into the material tray 330, the material can be accurately placed, that is, the placement position of the adhesive strip on the material tray 330 is more precise, and the accuracy of the subsequent grabbing mechanism 400 grabbing the adhesive strip and gluing operations is also higher, which can effectively improve the gluing accuracy of the gluing equipment 1000.
