Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a suction cup vacuum degree detection mechanism. Background Technology

[0002] During the transfer process, the electrode sheets are adsorbed using a suction cup to position them. The suction cup typically has multiple suction nozzles, each capable of creating negative pressure to attract the electrode sheet. During frequent use, one or more of the suction nozzles may attract foreign objects, causing blockages. If these nozzles are not cleaned promptly, the suction cup may fail to accurately position the electrode sheets during subsequent adsorption, thus affecting the quality of the battery cell. Utility Model Content

[0003] To address the problem of inaccurate electrode positioning caused by clogging of the suction cup nozzle, this invention provides a suction cup vacuum detection mechanism for detecting the vacuum level inside the nozzle hole on the suction cup, so as to facilitate timely cleaning of clogged nozzle holes.

[0004] The technical solution of this utility model is: a suction cup vacuum degree detection mechanism, used to detect the vacuum degree of a suction cup, wherein the suction cup includes multiple suction nozzle holes; the suction cup vacuum degree detection mechanism includes a detection stage, a positioning module and a vacuum detection device.

[0005] The testing station includes multiple vacuum holes, and the vacuum testing device includes multiple vacuum gauges, with each vacuum gauge connected to one of the multiple vacuum holes.

[0006] The detection platform is used to place the suction cup, and the positioning module is used to position the suction cup and the detection platform so that the plurality of suction nozzle holes of the suction cup are connected to at least a portion of the vacuum holes in a one-to-one correspondence.

[0007] The vacuum gauge is used to detect the vacuum level of the suction nozzle orifice.

[0008] The above-mentioned technical solution has the following advantages or beneficial effects: The suction cup vacuum degree detection mechanism is equipped with a detection platform and a vacuum gauge. The detection platform has vacuum holes that correspond one-to-one with multiple suction nozzle holes on the suction cup, and each vacuum hole is connected to a vacuum gauge. When it is necessary to detect the vacuum degree of the suction cup, the suction cup can be placed on the detection platform, and the positioning module is used to position the suction cup and the detection platform. Then, a vacuum is drawn into the vacuum holes. Since the suction nozzle holes are connected to the vacuum holes, the suction nozzle holes are also in a vacuum state. The vacuum gauge can display the air pressure value of each suction nozzle hole in real time. When a suction nozzle hole is blocked, it can be displayed on the vacuum gauge, so as to facilitate timely cleaning of the blocked suction nozzle hole. Therefore, by detecting the vacuum degree of the suction cup, it can be ensured that there is no blockage in each suction nozzle hole of the suction cup, thus ensuring the positioning effect of the suction cup on the electrode sheet and guaranteeing the quality of the battery cell.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] refer to Figure 1 The suction cup vacuum degree detection mechanism in this embodiment of the present invention may include a detection platform 100, a vacuum detection device 200, and a positioning module 300. The detection platform 100 is used to place the suction cup 10 to be tested, the positioning module 300 is used to position the suction cup 10 and the detection platform 100, and the vacuum detection device 200 is used to detect the vacuum degree of the suction cup 10 placed on the detection platform 100.

[0019] For details, please refer to the following: Figures 1 to 4 The suction cup 10 includes multiple suction nozzle holes 11, each of which can be evacuated to adsorb the electrode. The testing stage 100 is provided with multiple vacuum holes 110. When the suction cup 10 is placed on the testing stage 100 and positioned by the positioning module 300, the multiple vacuum holes 110 can be connected one-to-one with at least some of the vacuum holes 110 on the testing stage 100. The vacuum detection device 200 may include a vacuum gauge 210 connected one-to-one with the multiple vacuum holes 110. When the suction nozzle hole 11 is connected to the vacuum hole 110, the inside of the vacuum hole 110 can be in a vacuum state. At this time, the vacuum gauge 210 can detect the vacuum degree of the suction nozzle hole 11 to determine whether there is a blockage inside the suction nozzle hole 11.

[0020] The vacuum detection device 200 may also include a negative pressure module (not shown in the figure), which is used to evacuate each vacuum hole 110. When the suction nozzle hole 11 is in a vacuum state after being connected to the connecting hole 410, the vacuum gauge 210 can display the air pressure value in each suction nozzle hole 11 in real time. If the air pressure value in one or more suction nozzle holes 11 is detected to be abnormal, it indicates that the suction nozzle hole 11 is blocked. At this time, the suction nozzle hole 11 can be cleaned in time to ensure that there are no foreign objects blocking the suction nozzle hole 11. In this way, when using the suction cup 10 to adsorb the electrode sheet, the electrode sheet positioning can be accurately guaranteed, thereby ensuring the quality of the subsequent battery cell.

[0021] In this embodiment, the number of vacuum holes 110 provided on the testing platform 100 can be the same as the number of suction nozzle holes 11 on the suction cup 10. After the suction cup 10 and the testing platform 100 are positioned, each suction nozzle hole 11 of the suction cup 10 can be aligned and connected with each vacuum hole 110. Alternatively, the number of vacuum holes 110 provided on the testing platform 100 can be greater than the number of suction nozzle holes 11 on the suction cup 10. After the suction cup 10 and the testing platform 100 are positioned, each suction nozzle hole 11 of the suction cup 10 can be aligned and connected with some of the vacuum holes 110. When the number of vacuum holes 110 is greater than the number of suction nozzle holes 11, the arrangement of the vacuum holes 110 can be designed so that the testing platform 100 can be used to test the vacuum level of suction cups 10 of different specifications, which helps to reduce production costs.

[0022] In some embodiments, such as Figure 3 As shown, the positioning module 300 may include a first positioning module 310, a second positioning module 320, and a third positioning module 330. The first positioning module 310 can be used to position the suction cup 10 and the detection table 100 in a first direction. The second positioning module 320 can be used to position the suction cup 10 and the detection table 100 in a second direction. The third positioning module 330 can be used to position the suction cup 10 and the detection table 100 in a third direction. The first direction can be understood as the orientation of the suction cup 10 and the detection table 100 when the suction cup 10 is placed on the detection table 100. The second direction can be understood as the length direction of the detection table 100. The third direction can be understood as the width direction of the detection table 100. Furthermore, the first direction, the second direction, and the third direction are all perpendicular to each other.

[0023] Please refer to the above. Figures 3 to 5The first positioning module 310 may include multiple positioning clamping components 311, each of which may include a first clamping portion 3111 and a second clamping portion 3112 arranged along a first direction. When the suction cup 10 is placed on the detection table 100, the first clamping portion 3111 is located on the side of the suction cup 10 away from the detection table 100, and abuts against the end face of the suction cup 10 away from the detection table 100. The second clamping portion 3112 is located on the side of the detection table 100 away from the suction cup 10, and abuts against the side of the detection table 100 away from the suction cup 10. Thus, under the combined clamping action of the first clamping portion 3111 and the second clamping portion 3112, the suction cup 10 can be positioned relative to the detection table 100 in the first direction.

[0024] In this embodiment, the first clamping part 3111 and the second clamping part 3112 can move closer to or further away from each other along a first direction to change the distance between the first clamping part 3111 and the second clamping part 3112. When the suction cup 10 needs to perform vacuum testing, the first clamping part 3111 and the second clamping part 3112 can move closer to each other to clamp the suction cup 10 and the testing stage 100. After the suction cup 10 completes the testing, the first clamping part 3111 and the second clamping part 3112 can move further away from each other, thereby facilitating the removal of the suction cup 10 from the testing stage 100.

[0025] Based on this, the first positioning module 310 may further include a driving component, which can be used to drive the second clamping part 3112 to move along the first direction, thereby adjusting the distance between the first clamping part 3111 and the second clamping part 3112.

[0026] Specifically, such as Figure 5 As shown, the positioning and clamping component 311 may further include a limiting plate 3113, which is disposed opposite to the first clamping part 3111. The limiting plate 3113 and the first clamping part 3111 can be connected by a connecting plate 3114. In this case, the first clamping part 3111, the limiting plate 3113, and the connecting plate 3114 can form a U-shape. When the first clamping part 3111 is used to position the suction cup 10, the limiting plate 3113 is located on the side of the detection table 100 away from the suction cup 10, and the connecting plate 3114 is located on the side of the suction cup 10.

[0027] The second clamping part 3112 can be in the form of a push rod. The limiting plate 3113 is provided with a limiting groove 3119, which passes through the limiting plate 3113 along the first direction. The second clamping part 3112 can pass through the limiting groove 3119 and can contact the inner wall of the limiting groove 3119 so that the limiting groove 3119 can limit the second clamping part 3112 in the second direction and / or the third direction, thereby ensuring that the second clamping part 3112 can only move along the first direction.

[0028] The drive assembly may include a cam 3116, and a connecting plate 3114 is also connected to a connecting seat 3115. The cam 3116 is connected to the connecting seat 3115 via a rotating shaft 3117. The axis of the rotating shaft 3117 coincides with the axis of the cam 3116, and the rotating shaft 3117 is fixedly connected to the cam 3116. The rotating shaft 3117 is rotatably connected to the connecting seat 3115 so that the cam 3116 can rotate relative to the connecting seat 3115 about its own axis.

[0029] In this embodiment, reference is also made to Figure 5 and Figure 6 The cam 3116 is located at the bottom of the second clamping part 3112. When the cam 3116 is in the first state, the bottom of the second clamping part 3112 is in contact with the surface of the cam 3116, and the cam 3116 can support the second clamping part 3112. At this time, the distance between the second clamping part 3112 and the first clamping part 3111 is relatively large. When the cam 3116 rotates relative to the connecting seat 3115 to the second state, the cam 3116 can push the second clamping part 3112 upward, thereby reducing the distance between the second clamping part 3112 and the first clamping part 3111. In this way, the first clamping part 3111 and the second clamping part 3112 cooperate to clamp the suction cup 10 and the detection table 100.

[0030] In practical applications, refer again Figure 3 and Figure 4 Multiple positioning and clamping components 311 can be divided into two groups, and the two groups of positioning and clamping components 311 can be arranged on both sides of the detection table 100 along a third direction. Before the suction cup 10 is placed on the detection table 100, the two groups of positioning and clamping components 311 are away from the detection table 100. After the suction cup 10 is placed on the detection table 100, the two groups of positioning and clamping components 311 are respectively close to the detection table 100, so that the connecting plate 3114 can abut against the two opposite end faces of the detection table 100 along a third direction. At this time, the first clamping part 3111 overlaps the side of the suction cup 10 away from the detection table 100, and there is a gap between the second clamping part 3112 and the side of the detection table 100 away from the suction cup 10. Subsequently, the cam 3116 is rotated, and the second clamping part 3112 is pushed upward by the cam 3116, so that the second clamping part 3112 and the side end face of the detection table 100 opposite to the suction cup 10 are separated. In this way, the first clamping part 3111 and the second clamping part 3112 cooperate to clamp the suction cup 10 and the detection table 100.

[0031] After completing the vacuum test of the suction cup 10, the cam 3116 can be rotated first to disengage the second clamping part 3112 from the end face of the detection stage 100 away from the suction cup 10. Then, the positioning clamping part 311 is driven away from the detection stage 100 in a third direction, which makes it easier to remove the suction cup 10 from the detection stage 100.

[0032] It is worth mentioning that by placing the positioning clamping components 311 on both sides of the detection table 100 along a third direction, that is, on both sides of the width direction of the detection table 100, each side of the detection table 100 can have more space to arrange multiple positioning clamping components 311. Multiple clamping components can make the suction cup 10 bear force evenly and achieve a better positioning effect. For example, if two positioning clamping components 311 are arranged on each side of the detection table 100, the two positioning clamping components 311 can be symmetrically arranged on the long side of the detection table 100. Alternatively, if two positioning clamping components 311 are arranged on each side of the detection table 100, the distance between any two adjacent positioning clamping components 311 is equal.

[0033] In addition, the positioning clamping components 311 located on both sides of the testing table 100 are aligned one to one, that is, the two sets of positioning clamping components 311 are symmetrically arranged on the testing table 100.

[0034] Furthermore, such as Figure 5 As shown, in order to facilitate the rotation of the cam 3116, a handle 3118 can also be provided on the cam 3116. When it is necessary to drive the cam 3116 to rotate, the operator can manually hold the handle 3118 and rotate the cam 3116 to complete the movement of the second clamping part 3112, which is convenient for operation.

[0035] In other embodiments, the drive component may be, for example, a motor or a cylinder. In this case, the second clamping part 3112 may be connected to a guide rail extending along a first direction, the guide rail and the first clamping part 3111 are fixed relative to each other, and the drive component drives the second clamping part 3112 to move relative to the guide rail along the first direction, thereby adjusting the distance between the first clamping part 3111 and the second clamping part 3112.

[0036] Alternatively, the first positioning module 310 can also be in the form of a pressure plate. When the suction cup 10 is placed on the detection table 100, the pressure plate can be pressed against the side of the suction cup 10 facing away from the detection table 100. At this time, the pressure plate applies a squeezing force along the first direction to the suction cup 10, thereby enabling the suction cup to adhere tightly to the detection table 100 and complete the positioning.

[0037] Continue to refer to Figure 3 and Figure 4 The second positioning module 320 may include two sets of first positioning pins 321 arranged along the second direction, with the two sets of first positioning pins 321 disposed on both sides of the detection table 100 along the second direction. The first positioning pins 321 can be fixedly connected to the detection table 100. When the suction cup 10 is placed on the detection table 100, the two sets of first positioning pins 321 can respectively abut against the two end faces of the suction cup 10 arranged along the second direction, thereby achieving positioning of the suction cup 10 in the second direction.

[0038] For example, the first positioning pin 321 may be an L-shaped structure, specifically including a first positioning block 3211 and a second positioning block 3212. The first positioning block 3211 is fixedly connected to the side of the detection table 100, and extends along a first direction. The second positioning block 3212 is connected to the first positioning block 3211, and the second positioning block 3212 may also abut against the end face of the detection table 100 used to place the suction cup 10, thereby enhancing the fixing effect between the first positioning pin 321 and the detection table 100.

[0039] The second positioning block 3212 protrudes from the side of the first positioning block 3211 facing the detection table 100 along the second direction. When the suction cup 10 is placed on the detection table 100, the suction cup 10 abuts against the second positioning block 3212. In this way, the two second positioning blocks 3212 cooperate to position the suction cup 10 in the second direction.

[0040] Furthermore, to enhance the abutment effect between the first positioning pin 321 and the suction cup 10, a first elastic member 3213 may be provided on the side of the second positioning block 3212 facing the suction cup 10. The first elastic member 3213 can extend and retract in a second direction. Specifically, the second positioning block 3212 may be provided with a mounting hole, the opening of which faces the suction cup 10, and the first elastic member 3213 is disposed within the mounting hole.

[0041] When the first elastic member 3213 is in its initial state, one end of the first elastic member 3213 protrudes beyond the opening of the mounting hole, that is, the first elastic member 3213 protrudes beyond the end face of the second positioning block 3212 facing the suction cup 10. When the suction cup 10 is placed on the detection stage 100, the end face of the suction cup 10 can contact and press the first elastic member 3213, causing the first elastic member 3213 to retract toward the interior of the mounting hole. After the suction cup 10 is in place, one end of the first elastic member 3213 can still slightly protrude beyond the opening of the mounting hole, so that the suction cup 10 and the first elastic member 3213 always remain in contact.

[0042] In this embodiment, since first elastic members 3213 are respectively provided on both sides of the suction cup 10 along the second direction, the first elastic members 3213 on both sides are in contact with the suction cup 10, which also helps to make the suction cup 10 bear the force evenly and ensure the positioning effect of the suction cup 10 in the second direction.

[0043] In a specific implementation, the first elastic component 3213 may be, for example, an elastic ball.

[0044] In some other embodiments, the second positioning module 320 may also include two sets of first positioning blocks arranged along a second direction, with the suction cup 10 located between the two sets of first positioning blocks, and the two sets of first positioning blocks respectively abutting against the end face of the suction cup 10. Furthermore, at least one set of first positioning blocks can move relative to the detection stage 100 along the second direction to adjust the spacing between the two sets of first positioning blocks, so that the suction cup 10 can be quickly placed between the two sets of first positioning blocks. Exemplarily, the first positioning blocks can be moved by a motor drive.

[0045] Referring again to the figure, the third positioning module 330 in this embodiment may include two sets of second positioning pins 331. The two sets of second positioning pins 331 are arranged along a third direction and are respectively disposed on both sides of the detection table 100. The second positioning pins 331 can be fixed to the detection table 100. When the suction cup 10 is placed on the detection table 100, the two sets of second positioning pins 331 can abut against the two end faces of the suction cup 10 arranged along the third direction, so as to realize the positioning of the suction cup 10 in the third direction.

[0046] In this embodiment, the structure of the second positioning pin 331 can be the same as that of the first positioning pin 321, that is, the second positioning pin 331 is also an L-shaped structure. Specifically, the second positioning pin 331 may include a third positioning block 3311 and a fourth positioning block 3312. The third positioning block 3311 can be fixedly connected to the side of the detection table 100 and extends along the first direction. The fourth positioning block 3312 is connected to the third positioning block 3311, and the fourth positioning block 3312 protrudes from the side of the third positioning block 3311 facing the detection table 100 along the third direction. When the suction cup 10 is placed on the detection table 100, the suction cup 10 abuts against the fourth positioning block 3312, thereby positioning the suction cup 10 in the third direction by the fourth positioning blocks 3312 on both sides.

[0047] To enhance the positioning effect between the second positioning pin 331 and the suction cup 10, a second elastic member 3313 may be provided on the side of the fourth positioning block 3312 facing the suction cup 10. The second elastic member 3313 can extend and retract in a third direction. The installation method of the second elastic member 3313 can be the same as the installation method of the first elastic member 3213 in the aforementioned embodiment, and will not be described here.

[0048] When the second elastic member 3313 is in its initial state, its end protrudes beyond the end face of the fourth positioning block 3312 facing the suction cup 10. When the suction cup 10 is placed on the detection stage 100, the end face of the suction cup 10 contacts and presses against the second elastic member 3313. After the suction cup 10 is in place, the second elastic member 3313 remains in contact with the surface of the suction cup 10 to achieve the positioning effect of the suction cup 10.

[0049] Since each set of second elastic components 3313 is located on the long side of the detection stage 100, in practical applications, each set of second elastic components 3313 may include at least two second elastic components 3313, with any two adjacent second elastic components 3313 spaced apart, so that multiple second elastic components 3313 can cooperate to position the suction cup 10. Furthermore, by providing second elastic components 3313 on both sides of the suction cup 10 along a third direction, and ensuring that the second elastic components 3313 on both sides are in contact with the suction cup 10, the suction cup 10 is subjected to balanced force, thereby ensuring the positioning effect of the suction cup 10 in the third direction.

[0050] In a specific implementation, the second elastic component 3313 may be, for example, an elastic ball.

[0051] In some other embodiments, the third positioning module 330 may also include two sets of second positioning blocks arranged along a third direction, with the suction cup 10 located between the two sets of second positioning blocks, and the two sets of second positioning blocks respectively abutting against the end face of the suction cup 10. Furthermore, at least one set of second positioning blocks can move relative to the detection stage 100 along a third direction to adjust the spacing between the two sets of second positioning blocks, so that the suction cup 10 can be quickly placed between the two sets of second positioning blocks. Exemplarily, the second positioning blocks can be moved by a motor drive.

[0052] In some embodiments, refer again Figure 4 The side of the testing stage 100 where the suction cup 10 is placed may also be provided with a buffer layer 400. The buffer layer 400 is provided with connecting holes 410 that correspond one-to-one with the multiple vacuum holes 110 of the testing stage 100. The size of the connecting holes 410 may be the same as the size of the vacuum holes 110, and the connecting holes 410 and the vacuum holes 110 are arranged coaxially.

[0053] The buffer layer 400 can be made of materials such as rubber. When the suction cup 10 is placed on the inspection table 100, the larger surface of the suction cup 10 facing the inspection table 100 directly contacts the buffer layer 400. On the one hand, providing the buffer layer 400 on the inspection table 100 can reduce the impact between the suction cup 10 and the inspection table 100, thereby preventing the suction cup 10 from bumping when placed on the inspection table 100. On the other hand, since the buffer layer 400 is made of a flexible material, when the suction cup 10 is placed on the buffer layer 400, the suction cup 10 can fit tightly against the buffer layer 400, which can enhance the sealing effect between the suction cup 10 and the buffer layer 400.

[0054] Furthermore, a buffer pad (not shown in the figure) may also be provided on the side of the suction cup 10 facing the detection table 100. The buffer pad may have through holes corresponding one-to-one with multiple suction nozzle holes 11, with each through hole aligned with the suction nozzle hole 11. The material of the buffer pad may also be rubber. When the suction cup 10 is placed on the detection table 100, the buffer pad is in direct contact with the buffer layer 400, which makes the contact between the buffer pad and the buffer layer 400 tighter, thereby further enhancing the sealing effect between the suction cup 10 and the detection table 100.

[0055] In some embodiments, the diameter of the vacuum hole 110 on the detection stage 100 can be larger than the diameter of the suction nozzle hole 11 on the suction cup 10, which makes it easier to connect each suction nozzle hole 11 with each vacuum hole 110. Therefore, even if there is a positioning deviation between the suction cup 10 and the detection stage 100, the orthogonal projection of the suction nozzle hole 11 on the detection stage 100 can fall into the vacuum hole 110, thereby preventing air leakage between the suction nozzle hole 11 and the vacuum hole 110.

[0056] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
