Description

Technical Field

[0001] This application relates to the field of lithium battery production equipment technology, and in particular to a cell adhesive bonding device. Background Technology

[0002] A battery cell module is formed by stacking multiple battery cells. Before stacking the battery cells into a battery cell module, insulating spacers (such as mica sheets) need to be attached to the middle battery cells. Some spacers do not have adhesive surfaces, so before attaching the spacers, adhesive strips need to be applied to the battery cells first, and then the spacers are attached to the battery cells using the adhesive strips.

[0003] Current cell mounting devices can only attach spacers to the cells; they do not have adhesive application capabilities. Therefore, an adhesive application device is needed to first apply adhesive to the cells before transferring the cells with adhesive strips to the cell mounting device for final mounting.

[0004] Existing adhesive application devices typically use suction cups to pick up adhesive strips from the material handling station and deliver them to the application station, where they are applied to the battery cells. However, the suction cups are currently fixedly mounted on the drive mechanism of the application device. Since battery cells come in various sizes and specifications, the number and location of adhesive strips required for each specification also differ. Each time the battery cell specification is changed, the corresponding suction cup needs to be installed, resulting in cumbersome operation. Utility Model Content

[0005] The purpose of this application is to provide a battery cell adhesive applicator to solve the problem that the suction cups of existing adhesive applicators cannot be adapted to battery cells of different specifications.

[0006] To achieve this objective, the following technical solution is adopted in this application:

[0008] The adsorption mechanism includes a base, an adjustment component, and at least two adsorption elements. Each adsorption element is configured to adsorb or release an adhesive strip. The at least two adsorption elements are mounted on the base close to or far from each other. The adjustment component is disposed on the base and is configured to drive the at least two adsorption elements close to or far from each other to adjust the distance between the at least two adsorption elements, thereby adjusting the adhesive strip adsorbed by the at least two adsorption elements to a preset distance.

[0009] The drive mechanism is mounted on the frame, and the drive end of the drive mechanism is connected to the base. The drive mechanism is configured to drive the base to the adhesive dispensing station to adsorb at least two adhesive strips to be applied by at least two adsorption elements. The drive mechanism is also configured to drive the base to the adhesive application station to apply at least two adhesive strips adjusted to a preset spacing onto the battery cell by at least two adsorption elements.

[0010] The battery cell adhesive applicator proposed in this application achieves adhesive application for battery cells of different specifications by setting an adjustment component on the adsorption mechanism. After at least two adsorption elements adsorb the adhesive strip, the spacing between the adhesive strips adsorbed by the at least two adsorption elements is adjusted by the adjustment component, which enables adhesive application for battery cells of different specifications and has good compatibility. Moreover, the method of adjusting the spacing of the adhesive strip by adjusting the spacing of at least two adsorption elements simplifies the adhesive application process, improves adhesive application efficiency, and meets the requirements of fast-paced operation compared with setting a dedicated adjustment platform to adjust the spacing of the adhesive strip before adhesive application.

The driving end of the first driving member is connected to the two sliders respectively. The first driving member is configured to synchronously drive the two sliders to move along the first horizontal direction, so that the two sliders simultaneously move closer to or further away from the first adsorption member.

[0027] By setting two sliding parts, the adsorption mechanism can adsorb five adhesive strips at a time; through the cooperation of the first driving part and the two sliding parts, the two sliding parts are driven to move closer to or further away from the first adsorption part at the same time, so as to adjust the distance between the adhesive strips adsorbed by the first adsorption part and the two second adsorption parts in the first horizontal direction.

[0028] Optionally, the first driving component includes a motor, a driving pulley, a driven pulley, and a transmission belt, wherein:

By opening the first clearance opening and the second clearance opening on the base, and setting the first connector and the second connector to pass through the first clearance opening and the second clearance opening respectively, the first driving component is completely above the base, without occupying the external space of the base in the horizontal direction, thus avoiding interference with other external equipment.

Detailed Implementation

[0057] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] A battery cell module is formed by stacking multiple battery cells. Before stacking the battery cells into a battery cell module, insulating spacers (such as mica sheets) need to be attached to the middle battery cells. Some spacers do not have adhesive surfaces, so before attaching the spacers, adhesive strips need to be applied to the battery cells first, and then the spacers are attached to the battery cells using the adhesive strips.

[0059] Current cell mounting devices can only attach spacers to the cells; they do not have adhesive application capabilities. Therefore, an adhesive application device is needed to first apply adhesive to the cells before transferring the cells with adhesive strips to the cell mounting device for final mounting.

[0060] Existing adhesive application devices typically use suction cups to pick up adhesive strips from the material handling station and deliver them to the application station, where they are applied to the battery cells. However, the suction cups are currently fixedly mounted on the drive mechanism of the application device. Since battery cells come in various sizes and specifications, the number and location of adhesive strips required for each specification also differ. Each time the battery cell specification is changed, the corresponding suction cup needs to be installed, resulting in cumbersome operation.

[0061] Therefore, this application proposes a battery cell adhesive bonding device, please refer to [link to relevant documentation]. Figure 1 As shown, the battery cell adhesive applicator proposed in this embodiment includes a frame 10, a drive mechanism 20, and an adsorption mechanism 30. The adsorption mechanism 30 includes a base 31, an adjustment assembly 32, and at least two adsorption elements 33. Each adsorption element 33 is configured to adsorb or release an adhesive strip. At least two adsorption elements 33 are mounted on the base 31, which can be close to or far from each other. The adjustment assembly 32 is disposed on the base 31 and is configured to drive the at least two adsorption elements 33 to move closer to or further away from each other, so as to apply adhesive to the at least two adsorption elements 33. The spacing of 3 is adjusted to adjust the adhesive strips adsorbed by at least two adsorption members 33 to a preset spacing; the drive mechanism 20 is mounted on the frame 10, and the drive end of the drive mechanism 20 is connected to the base 31. The drive mechanism 20 is configured to drive the base 31 to move to the adhesive dispensing station to adsorb at least two adhesive strips to be applied by at least two adsorption members 33. The drive mechanism 20 is also configured to drive the base 31 to the adhesive application station to apply at least two adhesive strips adjusted to a preset spacing onto the battery cell by at least two adsorption members 33.

[0062] The battery cell adhesive applicator proposed in this application, by setting an adjustment component 32 on the adsorption mechanism 30, allows the at least two adsorption elements 33 to adjust the spacing of the adhesive strips adsorbed by the at least two adsorption elements 33 after adsorbing the adhesive strips. This enables adhesive application to battery cells of different specifications with good compatibility. Moreover, the method of adjusting the spacing of the adhesive strips by adjusting the spacing of the at least two adsorption elements 33 simplifies the adhesive application process, improves adhesive application efficiency, and meets the requirements of fast-paced operations compared to setting a dedicated adjustment platform to adjust the spacing of the adhesive strips before application.

[0063] Please see Figures 1 to 3 As shown, in one embodiment, the adjustable distance assembly 32 includes a first driving member 320 and at least one sliding member 321, and at least two adsorption members 33 include a first adsorption member 330 and a second adsorption member 331. The first adsorption member 330 is fixedly installed on the bottom surface of the base 31, and the sliding member 321 can move along a first horizontal direction ( Figure 1 The second adsorption member 331 is fixedly mounted on the sliding member 321. The driving end of the first driving member 320 is connected to the sliding member 321. The first driving member 320 is configured to drive the sliding member 321 to reciprocate along the first horizontal direction, so as to drive the second adsorption member 331 to move closer to or away from the first adsorption member 330.

[0064] As can be seen, through the cooperation of the first driving member 320 and the sliding member 321, the second adsorption member 331 is driven to move closer to or away from the first adsorption member 330, so as to adjust the distance between the two adhesive strips adsorbed by the two adsorption members in the first horizontal direction, providing a simple and easy-to-implement adjustable distance component 32.

[0065] In one embodiment, the spacing adjustment assembly 32 further includes a second driving member 322, and the cell adhesive applicator further includes a third adsorption member 332. The fixed end of the second driving member 322 is mounted on the sliding member 321, and the driving end of the second driving member 322 is connected to the third adsorption member 332. The second driving member 322 is configured to drive the third adsorption member 332 to move closer to or further away from the second adsorption member 331 along a first horizontal direction to adjust the spacing between the second adsorption member 331 and the third adsorption member 332.

[0066] Specifically, the second adsorption member 331 is fixedly installed on the end of the sliding member 321 near the first adsorption member 330, and the fixed end of the second driving member 322 is installed on the bottom surface of the sliding member 321.

[0067] Specifically, the second drive component 322 is a cylinder.

[0068] It can be seen that by setting the third adsorption element 332, at least three adhesive strips can be adsorbed at one time; by cooperating with the second driving element 322 and the third adsorption element 332, the spacing between the two adhesive strips adsorbed by the second adsorption element 331 and the third adsorption element 332 in the first horizontal direction can be adjusted.

[0069] In one embodiment, the second adsorbent 331 is located between the first adsorbent 330 and the third adsorbent 332; or, the third adsorbent 332 is located between the first adsorbent 330 and the second adsorbent 331.

[0070] It can be seen that by setting the first adsorption element 330, the second adsorption element 331 and the third adsorption element 332, two different arrangement forms of the first adsorption element 330, the second adsorption element 331 and the third adsorption element 332 are provided, which can meet different application scenarios.

[0071] Please see Figure 1 and Figure 4 As shown, in one embodiment, a sliding guide pair 34 is provided between the slider 321 and the base 31. The sliding guide pair 34 includes a linear guide rail 340 and a slider 341. The linear guide rail 340 is fixed to the bottom surface of the base 31 along a first horizontal direction, and the slider 341 is fixed to the slider 321 and slidably fitted onto the linear guide rail 340; or, the linear guide rail 340 is fixed to the slider 321 along a first horizontal direction, and the slider 341 is fixed to the bottom surface of the base 31 and slidably fitted onto the linear guide rail 340.

[0072] It can be seen that by setting a sliding guide pair 34 between the slider 321 and the base 31, the smoothness of the slider 321 reciprocating along the first horizontal direction is improved.

[0073] In one embodiment, the distance adjustment component 32 includes two sliders 321, which are respectively disposed on both sides of the first adsorption member 330 in the first horizontal direction. The driving end of the first driving member 320 is connected to the two sliders 321 respectively. The first driving member 320 is configured to synchronously drive the two sliders 321 to move along the first horizontal direction, so that the two sliders 321 simultaneously move closer to or further away from the first adsorption member 330.

[0074] As can be seen, by setting two sliding members 321, the adsorption mechanism 30 can adsorb five adhesive strips at a time; through the cooperation of the first driving member 320 and the two sliding members 321, the two sliding members 321 are driven to move closer to or further away from the first adsorption member 330 at the same time, so as to adjust the distance between the adhesive strips adsorbed by the first adsorption member 330 and the two second adsorption members 331 in the first horizontal direction.

[0075] In one embodiment, the first driving member 320 includes a motor 3200, a driving pulley (not shown), a driven pulley 3201, and a transmission belt 3202. The driving pulley and the driven pulley 3201 are rotatably mounted on the top surface of the base 31 at intervals along a first horizontal direction. The transmission belt 3202 is sleeved on the driving pulley and the driven pulley 3201. A first sliding member 321 is fixedly connected to the first side of the transmission belt 3202 via a first connecting member 35, and a second sliding member 321 is fixedly connected to the second side of the transmission belt 3202 via a second connecting member 36. The fixed end of the motor 3200 is vertically mounted on the top surface of the base 31. The rotating shaft of the motor 3200 is connected to the driving pulley. The motor 3200 is configured to drive the driving pulley to rotate, thereby driving the transmission belt 3202 to rotate through the cooperation of the driven pulley 3201, and thus causing the two sliding members 321 to move closer or further apart.

[0076] Specifically, the driving pulley and driven pulley 3201 are synchronous pulleys, and the transmission belt 3202 is a synchronous belt.

[0077] As can be seen, through the cooperation of the motor 3200, the driving pulley, the driven pulley 3201, and the transmission belt 3202, the two sliding parts 321 are driven to move closer or further apart, providing a first driving component 320 with high transmission efficiency, precise transmission ratio, and smooth driving. At the same time, the motor 3200, the driving pulley, the driven pulley 3201, and the transmission belt 3202 are all set on the top surface of the base 31, making reasonable use of the space above the base 31, resulting in a compact overall structure and small space occupation.

[0078] In one embodiment, the drive mechanism 20 includes a first transverse module 21, a first sliding seat 22, a second transverse module 23, a second sliding seat 24, and a lifting module 25, wherein: the first transverse module 21 is mounted on the frame 10; the first sliding seat 22 is slidably mounted on the frame 10 along a first horizontal direction and connected to the drive end of the first transverse module 21; the first transverse module 21 is configured to drive the first sliding seat 22 to reciprocate along the first horizontal direction; the second transverse module 23 is disposed on the first sliding seat 22; the second sliding seat 24 moves along a second horizontal direction (…). Figure 1 The second sliding module 23 (in the Y direction) is slidably mounted on the first sliding seat 22. The driving end of the second lateral module 23 is connected to the second sliding seat 24, and the second lateral module 23 is configured to drive the second sliding seat 24 to reciprocate along the second horizontal direction. The lifting module 25 is disposed on the second sliding seat 24, and the driving end of the lifting module 25 is connected to the base 31. The lifting module 25 is configured to drive the base 31 to lift. The base 31 has a first clearance opening 310 and a second clearance opening 311 arranged in parallel. Both the first clearance opening 310 and the second clearance opening 311 extend along the first horizontal direction. The first end of the first connecting member 35 is fixedly connected to... On one of the sliding members 321, the second end of the first connecting member 35 passes through the first clearance opening 310 and is fixedly connected to the first side of the transmission belt 3202. The first end of the second connecting member 36 is fixedly connected to the other sliding member 321, and the second end of the second connecting member 36 passes through the second clearance opening 311 and is fixedly connected to the second side of the transmission belt 3202. The driving end of the lifting module 25 extends downward with multiple support rods 37. The bottom ends of the multiple support rods 37 are fixed on the base 31. The multiple support rods 37 are respectively arranged on the base 31 outside the first clearance opening 310 and the second clearance opening 311.

[0079] Specifically, the first transverse module 21 and the second transverse module 23 are conventional linear modules with a motor and a ball screw transmission pair, while the lifting module 25 uses an electric cylinder.

[0080] Specifically, the first sliding seat 22 can be slidably mounted on the frame 10 along the first horizontal direction via a sliding guide pair composed of a linear guide rail and a slider.

[0081] As can be seen, through the cooperation of the first transverse module 21, the first sliding seat 22, the second transverse module 23, the second sliding seat 24, and the lifting module 25, the driving base 31 is able to move laterally in the first and second horizontal directions and move up and down in the height direction. By opening the first clearance opening 310 and the second clearance opening 311 on the base 31 and setting the first connector 35 and the second connector 36 to pass through the first clearance opening 310 and the second clearance opening 311 respectively, the first driving member 320 is completely above the base 31 and will not occupy the external space of the base 31 in the horizontal direction, thus avoiding interference with other external devices. The base 31 is fixedly connected to the driving end of the lifting module 25 by multiple support members 37, so that the adsorption mechanism 30 is at a suitable installation height.

[0082] In one embodiment, the distance adjustment component 32 includes two sliders 321, which are respectively disposed on both sides of the first adsorption component 330 in the first horizontal direction. The first driving component 320 includes two driving parts, each driving part corresponding to one slider 321. The driving end of the driving part is connected to the corresponding slider 321. The driving part is configured to drive the corresponding slider 321 to reciprocate along the first horizontal direction, so as to drive the corresponding slider 321 to move closer to or away from the first adsorption component 330.

[0083] Specifically, the first driving component 320 adopts a double-headed cylinder, and the two driving rods of the double-headed cylinder are respectively connected to two sliding components 321.

[0084] As can be seen, by setting two sliding members 321, the adsorption mechanism 30 can adsorb at least three adhesive strips at a time; through the cooperation of the first driving member 320 and the two sliding members 321, the two sliding members 321 are driven to move closer to or further away from the first adsorption member 330 at the same time, so as to adjust the distance between the adhesive strips adsorbed by the first adsorption member 330 and the two second adsorption members 331 in the first horizontal direction; at the same time, by setting the first driving member 320 to include two driving parts, each driving part drives the corresponding sliding member 321 to move back and forth in the first horizontal direction, the structure of the first driving member 320 is simplified.

[0085] Please see Figure 1 and Figure 5 As shown, in one embodiment, the adsorption member 33 includes a mounting plate 3300 and an adsorption part 3301. The mounting plate 3300 is mounted on the base 31. The adsorption part 3301 consists of a plurality of suction cups spaced apart on the mounting plate 3300 along a second horizontal direction, which adsorb or release an adhesive strip. Alternatively, the adsorption part 3301 is an adsorption plate disposed on the mounting plate 3300, which has a plurality of adsorption holes spaced apart along a second horizontal direction, which adsorb or release an adhesive strip.

[0086] It can be seen that by setting the adsorption part 3301, two different forms of adsorption elements 33 are provided, which can meet different application scenarios.

[0087] In one implementation, the adsorption element 33 is also used to adsorb the septum.

[0088] It can be seen that by setting the adsorption element 33 to also adsorb the separator, the automatic mounting of the separator is realized; at the same time, after the at least two adsorption elements 33 adsorb the separator, the spacing between the separators adsorbed by the at least two adsorption elements 33 is adjusted by the spacing adjustment component 32 to adapt to the battery cells of different specifications, and the compatibility is good.

[0089] Please see Figure 1 and Figure 2 As shown, taking the adsorption mechanism 30 adsorbing three adhesive strips at once as an example, the distance adjustment method of the adsorption mechanism 30 is explained: A first adsorption element 330 and two second adsorption elements 331 can be used to adsorb the three adhesive strips separately. Based on the required spacing of the three adhesive strips on the battery cell, the distance adjustment component 32 adjusts the distance between the two second adsorption elements 331 and the first adsorption element 330, and then adsorbs the three adhesive strips. Alternatively, the first adsorption element 330 and two second adsorption elements 331 can be used to adsorb the three adhesive strips first, and then the distance adjustment component 32 can be used to adjust the distance between the two second adsorption elements 331 and the first adsorption element 330.

[0090] It should be noted that the adsorption mechanism 30 provided in this embodiment can adsorb 1-5 adhesive strips at a time. Depending on the adhesive strip mounting spacing requirements of different battery cells, different combinations of the first adsorption element 330, two second adsorption elements 331 and two third adsorption elements 332 can be selected, which is flexible and will not be described in detail here.

[0091] The battery cell adhesive application device provided in this application has the following advantages:

[0092] 1) The spacing of the adhesive strips adsorbed by the adsorption component can be adjusted, enabling the application of adhesive to battery cells of different specifications with good compatibility;

[0093] 2) It can adsorb 1-5 adhesive strips at a time as needed, offering good flexibility and applicability;

[0094] 3) The layout of the adjustable distance component is reasonable, the overall structure is compact, and it occupies little space;

[0095] 4) Applicable to mounting film strips and spacers;

[0096] 5) The placement process is simple and the placement efficiency is high.

[0097] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
