Description

Technical Field

[0001] The utility model relates to the technical field of glue sticking devices, in particular to a glue sticking mechanism. Background Art

[0002] At present, most of the battery cells in the industry are diaphragm-equipped battery cells. The diaphragm-equipped battery cells are made by wrapping the diaphragm around multiple pole pieces in one circle when winding the end, so that multiple pole pieces and the diaphragm are fixed as one. However, the setting of the diaphragm will increase the cost of the battery cell. Therefore, the diaphragm-free battery cell has become a research trend. However, in the related technology, the multiple pole pieces of the diaphragm-free battery cell are not fixed well after the stacking is completed because there is no diaphragm wrapped around them. The pole pieces are very easy to be misplaced, resulting in poor coating of the positive and negative pole pieces (in the lamination process, it is necessary to ensure that the negative pole piece completely covers the positive pole piece, and there is a tolerance range. If it exceeds the tolerance range, it is considered to be poorly coated), and then short circuits, battery capacity deviations and other abnormalities occur. Therefore, there is room for improvement.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] Combine the following Figure 1-Figure 6 The gluing mechanism 10 according to the embodiment of the utility model is described in detail.

[0035] Reference Figure 1-Figure 3 As shown, the glue sticking mechanism 10 according to the embodiment of the utility model may include a transfer table 1, a clamping assembly 2 and a glue sticking assembly 3.

[0036] The transfer table 1 is used to place the adhesive-bonded parts, and the transfer table 1 can be raised and lowered. When the adhesive-bonded parts are placed on the transfer table 1 and the transfer table 1 is raised and lowered, the transfer table 1 can drive the adhesive-bonded parts to be raised and lowered synchronously, so as to raise and lower the adhesive-bonded parts to a suitable position. Figure 1 As shown, the transfer platform 1 can rise along the F5 direction and descend along the F6 direction.

[0037] The clamping assembly 2 includes a fixed rotating clamp 21, which is suitable for approaching or moving away from the turntable 1. The fixed rotating clamp 21 has a clamping arm for clamping the adhesive-bonded piece. The turntable 1 can drive the adhesive-bonded piece to be lifted or lowered to a clamping position, at which the fixed rotating clamp 21 can approach the turntable 1 and clamp the adhesive-bonded piece. When it is not necessary to clamp the adhesive-bonded piece, the fixed rotating clamp 21 moves away from the turntable 1.

[0038] The fixed rotating clamp 21 can rotate to drive the adhesive-bonded piece to rotate, so that the adhesive-bonded piece can be rotated, which is convenient for subsequent adhesive bonding of the adhesive-bonded piece in a full circle. Figure 2 As shown, the fixed rotating clamp 21 can clamp the glue-applied piece and rotate it around the direction R1. Of course, in some embodiments, the fixed rotating clamp 21 can also clamp the glue-applied piece and rotate it around the opposite direction of R1, or the fixed rotating clamp 21 can clamp the glue-applied piece and rotate it back and forth around the direction R1 and the opposite direction of R1.

[0039] The gluing assembly 3 includes a gluing robot 31, which is suitable for approaching or moving away from the transfer table 1. The gluing robot 31 can be raised and lowered, and the gluing robot 31 is used to stick the adhesive tape 30 on the piece to be glued. After the fixed rotating clamp 21 clamps the piece to be glued, the gluing robot 31 is used to stick the adhesive tape 30 on the piece to be glued. When the gluing robot 31 is raised and lowered, it can glue the piece to be glued from multiple directions to simplify the gluing operation and improve the gluing efficiency. When the gluing robot 31 is close to the transfer table 1, it is convenient to glue the piece to be glued. When the gluing robot 31 is away from the transfer table 1, it can return to the waiting position and exit the gluing action. The gluing robot 31 cooperates with the clamping arm to achieve a full circle of gluing on the piece to be glued.

[0040] In some embodiments of the present invention, referring to Figure 1 , Figure 6 As shown, the part to be glued is a battery cell 20 without a diaphragm. The battery cell 20 is formed by stacking multiple pole pieces. The battery cell 20 is divided into a pole piece body 203, a first pole ear 201, and a second pole ear 202. The first pole ear 201 and the second pole ear 202 both extend from the pole piece body 203. The adhesive tape 30 is used to wrap around the pole piece body 203, so that the relative positions of the multiple pole pieces are fixed and not easily misplaced. In this way, the negative pole piece among the multiple pole pieces can completely cover the positive pole piece, and the coating tolerance range of the negative pole piece and the positive pole piece is within the preset tolerance range, thereby avoiding abnormalities such as short circuit and battery capacity deviation caused by poor coating of the negative pole piece and the positive pole piece.

[0041] One of the first pole ear portion 201 and the second pole ear portion 202 is a positive pole ear, and the other is a negative pole ear. Optionally, in some embodiments, the first pole ear portion 201 is an aluminum pole ear, and the second pole ear portion 202 is a copper pole ear; of course, in other embodiments, the first pole ear portion 201 may be a copper pole ear, and the second pole ear portion 202 may be an aluminum pole ear.

[0042] In other embodiments of the present invention, the part to be glued is a packaging box, and the gluing mechanism 10 can be used to glue and pack the packaging box.

[0043] In some other embodiments of the present invention, the part to be glued may also be other devices that require glue, such as decorations, exercise books, etc., which are not listed here one by one.

[0044] According to the gluing mechanism 10 of the embodiment of the utility model, by setting a liftable transfer table 1, the workpiece to be glued can be lifted and lowered to a suitable position, so that the fixed rotating clamp 21 clamps the workpiece to be glued and rotates the workpiece to be glued, and then it is convenient for the gluing robot 31 to stick the adhesive tape 30 on the workpiece to be glued, thereby completing the gluing action on the workpiece to be glued, such as the diaphragm-free battery cell 20, the packaging box, etc., so that the structure of the workpiece to be glued is fixed.

[0045] In some embodiments of the present invention, the fixed rotating clamp 21 is adapted to move in a first direction to approach or move away from the transfer table 1, and the glue sticking robot 31 is adapted to move in a second direction to approach or move away from the transfer table 1, and the first direction and the second direction are different directions. Figure 1 In the F1-F2 direction shown in FIG, for the clamping assembly 2 (i.e., the first clamping assembly 2a) on the F2 side of the transfer table 1, its fixed rotating clamp 21 can move along the F1 direction to approach the transfer table 1, and move along the F2 direction to move away from the transfer table 1. The second direction is Figure 1 , Figure 3 In the F3-F4 direction shown in FIG, for the glue sticking assembly 3 (i.e., the first glue sticking assembly 3a) on the F3 side of the transfer table 1, its glue sticking robot 31 can move along the F4 direction to approach the transfer table 1, and move along the F3 direction to move away from the transfer table 1. The first direction and the second direction are different directions, so that the fixed rotating clamp 21 and the glue sticking robot 31 are not easy to interfere with each other when moving, making the overall structural layout more reasonable, and can also make full use of the space in the first direction and the second direction.

[0046] Optionally, the first direction and the second direction may be directions perpendicular to each other, or directions having an acute angle therebetween.

[0047] In some embodiments not shown in the figure, the first direction and the second direction may also be the same direction. In this way, when the fixed rotating clamp 21 and the glue sticking robot 31 are both approaching the transfer table 1 or both moving away from the transfer table 1, the movement directions of the two are the same.

[0048] In some embodiments of the present invention, the gluing mechanism 10 further includes a transfer table lifting drive mechanism, which is used to drive the transfer table 1 to lift. The transfer table lifting drive mechanism can provide a driving force for the transfer table 1 to lift along the F5-F6 direction to adjust the specific position of the piece to be glued in the F5-F6 direction. Figure 1 In the specific example, the F5-F6 direction is the height direction of the glue sticking mechanism 10.

[0049] Optionally, the transfer table lifting drive mechanism can be a combination of a cylinder or a hydraulic cylinder or a rotating motor and a transmission mechanism, wherein the transmission mechanism can be a rack and pinion mechanism, wherein the rotating motor drives the gear to rotate, and the gear rotates to drive the rack to move linearly, and the rack is connected to the transfer table 1, and the rack moves linearly, and drives the transfer table 1 to move synchronously. The transmission mechanism can also be a screw and nut mechanism, etc., wherein the rotating motor drives the screw to rotate, and the screw rotates to drive the nut to move linearly, and the nut is connected to the transfer table 1, and the nut moves linearly, and drives the transfer table 1 to move synchronously. These lifting drive mechanisms are common mechanical structures in the mechanical field, and their working principles will not be described here in detail.

[0050] In some embodiments of the present invention, the glue sticking mechanism 10 further includes a turntable rotation driving mechanism, which is used to drive the turntable 1 to rotate. Figure 1 In a specific example, the turntable rotation drive mechanism can drive the turntable 1 to rotate in a horizontal plane, so that it is convenient to glue the adhesive-coated parts from different directions. Optionally, the turntable rotation drive mechanism can be a rotary motor or a combination of a rotary motor and a transmission mechanism, wherein the transmission mechanism can be a gear transmission mechanism, a belt transmission mechanism, etc. Similarly, these rotary drive mechanisms are common mechanical structures in the mechanical field, and their working principles are not described in detail here.

[0051] In some embodiments of the present invention, referring to Figure 1-Figure 2 As shown, the gluing mechanism 10 further includes a first slide rail 4, and the clamping assembly 2 further includes a first support frame 22. The first support frame 22 is slidably matched with the first slide rail 4. The first support frame 22 is suitable for approaching or moving away from the transfer table 1, and the fixed rotating clamp 21 slides with the first support frame 22 to approach or move away from the transfer table 1. The transfer table 1 is in the gluing position, and the first slide rail 4 extends toward the gluing position. When the gluing mechanism 10 is specifically used, a first driving mechanism can be provided to drive the first support frame 22 to move on the first slide rail 4. For the clamping assembly 2 (i.e., the first clamping assembly 2a) on the F2 side of the transfer table 1, when the first support frame 22 moves along the first slide rail 4 toward the F1 direction, it can drive the fixed rotating clamp 21 to approach the transfer table 1, and when the first support frame 22 moves along the first slide rail 4 toward the F2 direction, it can drive the fixed rotating clamp 21 away from the transfer table 1.

[0052] In some embodiments of the present invention, referring to Figure 2 As shown, the clamping assembly 2 also includes a clamp rotation driving mechanism 23, which is installed on the first support frame 22, and is used to drive the fixed rotating clamp 21 to rotate. When the fixed rotating clamp 21 rotates, it can drive the glue-applied workpiece to rotate synchronously, so that the adhesive tape 30 at the glue-applied robot 31 can be wrapped around the periphery of the glue-applied workpiece.

[0053] In some embodiments of the present invention, referring to Figure 2 As shown, the clamping assembly 2 further includes a clamp mounting plate 24, the fixed rotating clamp 21 is mounted on the clamp mounting plate 24, and the clamp rotation driving mechanism 23 drives the clamp mounting plate 24 to rotate to drive the fixed rotating clamp 21 to rotate. Optionally, the clamp rotation driving mechanism 23 can be a rotary motor or a combination of a rotary motor and a transmission mechanism, wherein the transmission mechanism can be a gear transmission mechanism, a belt transmission mechanism, etc.

[0054] In some embodiments of the present invention, referring to Figure 2As shown, each fixed rotating clamp 21 has two clamping arms, and a clamping space is formed between the two clamping arms. The adhesive-bonded piece is suitable to be clamped in the clamping space. The clamping assembly 2 also includes a clamping drive mechanism 25, which is installed on the clamp mounting plate 24. The clamping drive mechanism 25 is used to drive at least one clamping arm to move to adjust the size of the clamping space, so that the size of the clamping space is adapted to the adhesive-bonded piece, so as to more firmly clamp the adhesive-bonded piece. Specifically, each fixed rotating clamp 21 includes a first clamping arm 211 and a second clamping arm 212. The clamping space is formed between the first clamping arm 211 and the second clamping arm 212. The clamping drive mechanism 25 is used to drive at least one of the first clamping arm 211 and the second clamping arm 212 to move to adjust the size of the clamping space, specifically to adjust the distance between the first clamping arm 211 and the second clamping arm 212, so that the distance between the first clamping arm 211 and the second clamping arm 212 is adapted to the adhesive-bonded piece.

[0055] In some embodiments of the present invention, referring to Figure 2 As shown, a clamping slide rail 26 is provided on the clamp mounting plate 24, and the clamping arm slides and cooperates with the clamping slide rail 26, thereby the movement of the clamping arm is smoother, and the size of the clamping space can be adjusted conveniently. Optionally, one of the clamping arms can slide and cooperate with the clamping slide rail 26, or both clamping arms can slide and cooperate with the clamping slide rail 26.

[0056] Optionally, the clamping drive mechanism 25 can be a combination of a cylinder or a hydraulic cylinder or a rotary motor and a transmission mechanism, wherein the transmission mechanism can be a gear rack mechanism, wherein the rotary motor drives the gear to rotate, and when the gear rotates, the gear drives the rack to move linearly, and the rack is connected to the corresponding clamping arm, and when the rack moves linearly, the corresponding clamping arm is driven to move synchronously. The transmission mechanism can also be a screw nut mechanism, etc., wherein the rotary motor drives the screw to rotate, and when the screw rotates, the nut is driven to move linearly, and the nut is connected to the corresponding clamping arm, and when the nut moves linearly, the corresponding clamping arm is driven to move synchronously.

[0057] In a specific example, each fixed rotating clamp 21 includes a first clamping arm 211 and a second clamping arm 212, and the clamping drive mechanism 25 includes a rotating motor and a screw-nut mechanism, the screw-nut mechanism includes a screw, a first nut and a second nut, the screw includes a first thread segment and a second thread segment, the first thread segment and the second thread segment have opposite rotation directions, the first nut is threadedly matched with the first thread segment, the first nut is also connected to the first clamping arm 211, the second nut is threadedly matched with the second thread segment, and the second nut is also connected to the second clamping arm 212. The rotating motor drives the screw to rotate, and when the screw rotates in the forward direction, the first nut and the second nut are driven to approach each other, thereby driving the first clamping arm 211 and the second clamping arm 212 to approach each other; when the screw rotates in the reverse direction, the first nut and the second nut are driven to move away from each other, thereby driving the first clamping arm 211 and the second clamping arm 212 to move away from each other.

[0058] In some embodiments of the present invention, referring to Figure 1-Figure 2 As shown, the first support frame 22 may include a first vertical plate 221 and a first horizontal plate 222. The first vertical plate 221 is connected to the first horizontal plate 222. The first vertical plate 221 extends upward relative to the first horizontal plate 222. The first horizontal plate 222 is slidably matched with the first slide rail 4. The clip rotation drive mechanism 23 is installed on the first vertical plate 221. Optionally, the first vertical plate 221 is configured as a vertical plate, and the first horizontal plate 222 is configured as a horizontal plate.

[0059] In some embodiments of the present invention, referring to Figure 1 , Figure 3 As shown, the gluing mechanism 10 also includes a second slide rail 5, and the gluing assembly 3 also includes a second support frame 32. The second support frame 32 slides with the second slide rail 5. The second support frame 32 is suitable for approaching or moving away from the transfer table 1. The gluing robot 31 slides with the second support frame 32 to approach or move away from the transfer table 1, thereby realizing the extension or retraction action of the gluing robot 31 to the part to be glued. The transfer table 1 is in the gluing position, and the second slide rail 5 extends toward the gluing position. When the gluing mechanism 10 is used specifically, a second driving mechanism can be set to drive the second support frame 32 to move on the second slide rail 5. For the gluing component 3 (i.e., the first gluing component 3a) on the F3 side of the transfer table 1, when the second support frame 32 moves along the second slide rail 5 toward the F4 direction, it can drive the gluing robot 31 to approach the transfer table 1, thereby facilitating the gluing robot 31 to glue the parts to be glued; when the second support frame 32 moves along the second slide rail 5 toward the F3 direction, it can drive the gluing robot 31 away from the transfer table 1, thereby facilitating the gluing robot 31 to exit the gluing action and return to the waiting position or standby position.

[0060] In some embodiments of the present invention, referring to Figure 1 , Figure 3As shown, the glue sticking assembly 3 also includes a manipulator lifting drive mechanism 33, which is installed on the second support frame 32, and is used to drive the glue sticking manipulator 31 to rise and fall. The second support frame 32 may be provided with a first limiting groove 323, which extends along the lifting direction (i.e., the F5-F6 direction) of the glue sticking manipulator 31, and the manipulator lifting drive mechanism 33 is at least partially located in the first limiting groove 323, thereby, the upper wall of the first limiting groove 323 can limit the upper limit position of the manipulator lifting drive mechanism 33 in the F5-F6 direction, and the lower wall of the first limiting groove 323 can limit the lower limit position of the manipulator lifting drive mechanism 33 in the F5-F6 direction, thereby limiting the upper limit position and the lower limit position of the glue sticking manipulator 31 in the F5-F6 direction, and preventing the glue sticking manipulator 31 from slipping off the second support frame 32.

[0061] In some embodiments of the present invention, referring to Figure 3 As shown, the robot lifting drive mechanism 33 is connected to the glue sticking robot 31 via a connecting piece 34 .

[0062] In some optional embodiments of the present invention, the glue sticking assembly 3 may further include a manipulator telescopic drive mechanism, which is installed on the second support frame 32 or the manipulator lifting drive mechanism 33, and is used to drive the glue sticking manipulator 31 to move closer to or away from the transfer table 1. Figure 1 , Figure 3 As shown, the manipulator telescopic drive mechanism is installed on the manipulator lifting drive mechanism 33. The manipulator telescopic drive mechanism can drive the glue sticking manipulator 31 to move in the F4 direction, thereby facilitating the glue sticking manipulator 31 to stick glue to the workpiece to be glued. The manipulator telescopic drive mechanism can also drive the glue sticking manipulator 31 to move in the F3 direction, thereby facilitating the glue sticking manipulator 31 to exit the gluing action and return to the waiting position or standby position.

[0063] In some embodiments of the present invention, the gluing assembly 3 further includes a tape cutter 35, which is disposed on the gluing robot 31 or the second support frame 32, and is used to cut the tape 30. Figure 1 In the example, the adhesive tape cutter 35 is arranged on the gluing robot 31 . In some embodiments not shown in the figure, the adhesive tape cutter 35 can also be arranged on the second support frame 32 .

[0064] The steps of the adhesive tape 30 being attached to the adhesive workpiece by the adhesive tape robot 31 and the adhesive tape cutter 35 being used to cut the adhesive tape 30 are as follows: Figure 4Specifically, in step A, the gluing robot 31 moves forward to the gluing position; in step B, the adhesive tape 30 is attached to the piece to be glued and then returns to the waiting position; in step C, the piece to be glued is rotated by the fixed rotating clamp 21 for one circle; in step D, during the rotation of the piece to be glued, the adhesive tape 30 is wound around the outside of the piece to be glued; in step E, the gluing robot 31 descends to the bottom of the piece to be glued and moves forward, completes the finishing and uses the adhesive tape cutter 35 to cut the adhesive tape 30; in step F, the gluing robot 31 returns and rises to the waiting position.

[0065] In some embodiments of the present invention, referring to Figure 3 As shown, the glue sticking assembly 3 further includes an unwinding shaft 36, which is rotatably mounted on the second support frame 32, and the adhesive tape 30 is wound on the unwinding shaft 36, thereby realizing the storage of the adhesive tape 30. When the glue sticking robot 31 pulls out the adhesive tape 30 for sticking glue to the adhesive workpiece, the unwinding shaft 36 rotates forward. When the unwinding shaft 36 rotates in the reverse direction, the excess unwound adhesive tape 30 can be rewound on the rewinding shaft.

[0066] In some embodiments of the present invention, referring to Figure 1 , Figure 3 , Figure 5 As shown, the glue sticking assembly 3 further includes a buffer mechanism 37, which is arranged on the side of the glue sticking robot 31 away from the transfer table 1. Specifically, the buffer mechanism 37 is arranged between the unwinding shaft 36 and the glue sticking robot 31. The buffer mechanism 37 includes a plurality of buffer rollers, which are arranged at intervals and rotatably mounted on the second support frame 32. The plurality of buffer rollers are alternately attached to the two sides of the adhesive tape 30. The buffer mechanism 37 can offset the problem of the unwinding shaft 36 being over-released and the adhesive tape 30 being broken due to the sudden change of the tension on the adhesive tape 30 and the excessive glue pulling.

[0067] exist Figure 1 , Figure 5 In the embodiment of the present invention, the buffer mechanism 37 includes three buffer rollers, namely, a first buffer roller 371, a second buffer roller 372, and a third buffer roller 373. The first buffer roller 371, the second buffer roller 372, and the third buffer roller 373 are spaced apart from each other and rotatably mounted on the second support frame 32. The second buffer roller 372 is located between the first buffer roller 371 and the third buffer roller 373. The first buffer roller 371 and the third buffer roller 373 are both against the lower side of the adhesive tape 30, and the second buffer roller 372 is against the upper side of the adhesive tape 30.

[0068] When the adhesive tape 30 is subjected to a pulling force in the direction of arrow R2, the adhesive tape 30 will transfer the pulling force to the second cache roller 372 and the adhesive tape 30 on the other side of the second cache roller 372. The pulling force will pull the second cache roller 372 upward, that is, in the direction of arrow R3, thereby offsetting the problem of over-release of the unwinding shaft 36 and breaking of the adhesive tape 30 caused by sudden change in pulling force and too fast pulling of the adhesive.

[0069] After completing one gluing action, the buffer roller slowly descends to the initial position under the action of gravity, specifically, the second buffer roller 372 slowly descends to the initial position under the action of gravity.

[0070] In some embodiments of the present invention, referring to Figure 1 , Figure 3 , Figure 5 As shown, a second limiting groove 324 is opened on the second support frame 32, and the second limiting groove 324 extends along the F5-F6 direction. The second cache roller 372 is at least partially located in the second limiting groove 324. The upper wall of the second limiting groove 324 can limit the upper limit position of the second cache roller 372 in the F5-F6 direction, and the lower wall of the second limiting groove 324 can limit the lower limit position of the second cache roller 372 in the F5-F6 direction, thereby preventing the second cache roller 372 from slipping off the second support frame 32.

[0071] In some embodiments of the present invention, referring to Figure 1 , Figure 3 As shown, the glue assembly 3 also includes a limit roller 38 and a glue pressing drive 39. The limit roller 38 is arranged between the buffer mechanism 37 and the glue applying manipulator 31. The limit roller 38 is rotatably mounted on the second support frame 32. The glue pressing drive 39 is arranged opposite to the limit roller 38. The adhesive tape 30 passes between the glue pressing drive 39 and the limit roller 38. The glue pressing drive 39 presses the adhesive tape 30 against the limit roller 38. The pressing force of the glue pressing drive 39 on the adhesive tape 30 is adjustable. The glue pressing drive 39 is installed on the second support frame 32. Optionally, the glue pressing drive 39 can be a glue pressing cylinder or a glue pressing hydraulic cylinder or other drive that can provide a pressing force. The limit roller 38 can ensure that the tape 30 has a consistent tape route to prevent tape flying. The glue pressing driving member 39 cooperates with the limiting roller 38 to press and fix the adhesive tape 30 when it is not unwound, so as to prevent the adhesive tape 30 from rebounding under the pulling of the buffer mechanism 37.

[0072] Optionally, the number of the limiting rollers 38 may be one or more, and the glue pressing driving member 39 is arranged opposite to at least one limiting roller 38 .

[0073] In some embodiments of the present invention, referring to Figure 1 , Figure 3As shown, the glue sticking assembly 3 further includes a negative pressure adsorption member 311, which is disposed on the glue sticking robot 31 and is used to adsorb the non-adhesive surface of the adhesive tape 30. The negative pressure adsorption member 311 can provide negative pressure, thereby adsorbing the non-adhesive surface of the adhesive tape 30, so as to ensure that the glue sticking robot 31 can drive the adhesive tape 30 to be attached to the workpiece to be glued. The negative pressure adsorption member 311 can be a vacuum tube, which forms a negative pressure by transmitting a vacuum to the glue sticking robot 31.

[0083] Combination Figure 1 and Figure 6 When gluing the part to be glued, the part to be glued can be placed at the first gluing position P, the first clamping assembly 2a and the second clamping assembly 2b can be used to clamp the part to be glued, and then the first gluing assembly 3a can be used to glue the part to be glued to form a first adhesive tape ring 40. Then, the part to be glued is placed at the second gluing position Q, the transfer table 1 is rotated by a certain angle (for example, 90°), the third clamping assembly 2c and the fourth clamping assembly 2d can be used to clamp the part to be glued, and then the second gluing assembly 3b can be used to glue the part to be glued to form a second adhesive tape ring 50.

[0085] Optionally, the part to be glued may be fixed by wrapping it with multiple layers of glue, or the part to be glued may be fixed by full-wrap or half-wrap glue.

[0086] The following describes a process of gluing a cell 20 without a separator using the gluing mechanism 10 of the embodiment of the utility model.

[0087] When the transfer robot (not shown in the figure) transfers the battery cell 20 to the transfer table 1, the first clamping component 2a moves along the first slide rail section 4a, and the second clamping component 2b which is linked with the first clamping component 2a moves along the first slide rail second section 4b to the transfer table 1. After moving into place, the two clamping arms of the first fixed rotating clamp 21a of the first clamping component 2a and the two clamping arms of the second fixed rotating clamp 21b of the second clamping component 2b move towards each other along the corresponding clamping slide rails 26 under the connection and drive of the clamping drive mechanism 25, thereby clamping the battery cell 20. The clamping arms and the clamping slide rails 26 are connected by sliders, which is beneficial to reduce friction and reduce mechanism wear.

[0088] After the battery cell 20 is clamped, the transfer table 1 sinks under the drive of the transfer table lifting drive mechanism, and the transfer table 1 is separated from the battery cell 20 to prevent the transfer table 1 from interfering with the battery cell 20. The first glue sticking component 3a on the left side moves to the right along the second slide rail section 5a. After it is in place, the glue sticking robot 31 sinks (at this time, the glue sticking robot 31 has already absorbed the adhesive tape 30) and sticks the adhesive tape 30 on the battery cell 20. After sticking, the first glue sticking component 3a returns to the waiting position (the glue sticking robot 31 also returns accordingly), and at the same time, the first fixed rotating clamp 21a and the second fixed rotating clamp 21b rotate one circle under the drive of the clamp rotation drive mechanism 23. After completion, the glue sticking robot 31 sinks and extends to the first glue cutting position P. During the extension process, the adhesive tape cutter 35 cuts the adhesive tape 30. At the same time, the glue sticking robot 31 sticks the cut end of the adhesive tape 30 on the battery cell 20 to the battery cell 20. After that, the adhesive sticking robot 31 returns to the initial position to complete the adhesive sticking in the long side direction. During the process, the unwinding shaft 36 of the adhesive paper 30 is not connected to a power device such as a servo motor, so it can be pulled and unwound. At the same time, in order to prevent the unwinding shaft 36 from being over-released and the adhesive paper 30 from being pulled off, a buffer mechanism 37 of the adhesive paper 30 is added.

[0089] After the gluing in the long side direction is completed, the transfer table 1 rises to the initial position, the first fixed rotating clamp 21a and the second fixed rotating clamp 21b are opened and retracted, and the battery cell 20 returns to the transfer table 1. The transfer table 1 drives the battery cell 20 to move horizontally to the right to the second gluing position Q and rotates 90°, and then the gluing in the short side direction is carried out. The gluing action in the short side direction is the same as the gluing action in the long side direction, and the whole set of actions is completed. The product after gluing is as follows Figure 6 shown.

[0090] The glue sticking mechanism 10 according to the embodiment of the utility model has a simple structure and low manufacturing cost, can effectively fix the workpiece to be glued, is easy to operate, and has low precision requirements.
