[0039] It should be noted that this embodiment does not limit the number of dispensing mechanisms. The number of dispensing mechanisms can be one group, or two, three, four, five or more groups. Multiple groups of dispensing mechanisms are arranged at intervals in the horizontal direction, and the specific selection can be made according to actual conditions.

[0040] In this embodiment, when dispensing is required, the dispensing mechanism can be set above the substrate along the width direction of the substrate. By setting a displacement detection component 4 on the first adjustment component 3, the moving distance of the dispensing component 2 is detected in real time and fed back to the first adjustment component 3. The first adjustment component 3 adjusts the dispensing distance between the dispensing component 2 and the substrate according to the preset spacing and the real-time feedback moving distance, and stops after adjusting the dispensing component 2 to the appropriate position, so as to facilitate the precise control of the spacing between the dispensing component 2 and the substrate, improve the adjustment accuracy of the thickness of the insulating glue, and thus improve the yield rate of the electrode.

[0041] Example 2

[0042] As a further improvement to Example 1, Figures 2 to 4 As shown, the first adjustment component 3 includes a first driving member 301 and a linear slide module 302; the linear slide module 302 is arranged on the support frame 1, and the dispensing component 2 is arranged at the adjustment end of the linear slide module 302; the displacement detection member 4 is arranged at the fixed end of the linear slide module 302; the output end of the first driving member 301 is connected to the input end of the linear slide module 302, suitable for driving the adjustment end of the linear slide module 302 to move in the vertical direction; the displacement detection member 4 is communicatively connected with the first driving member 301.

[0043] It should be noted that the linear slide module 302 has a fixed end and an adjustable end. The fixed end of the linear slide module 302 is arranged on the support frame 1 ; the displacement detection component 4 is arranged at the fixed end of the linear slide module 302 .

[0044] In this embodiment, the first driving member 301 provides driving force to drive the adjustment end of the linear slide module 302 to move, and then the adjustment end of the linear slide module 302 drives the dispensing component 2 to move in the vertical direction for adjustment. At the same time, the first driving member 301 can stop after adjusting the dispensing component 2 to the appropriate position according to the preset spacing and the moving distance fed back in real time, thereby further improving the adjustment accuracy.

[0045] Specifically, the first driving member 301 is a servo motor, and the linear slide module 302 includes a support seat, a screw rod, a linear slide rail and a third slider. The support seat is arranged on the support frame 1, and the linear slide rail is arranged on the support seat in the vertical direction. The third slider is slidably connected to the linear slide rail; the screw rod is rotatably arranged on the support seat in the vertical direction, and the screw rod is connected to the third slider through a nut seat; the servo motor is arranged on the support seat, and the output end of the servo motor is connected to the screw rod drive, which is suitable for driving the screw rod to rotate; the glue dispensing component 2 is arranged on the third slider. The servo motor drives the screw rod to rotate, and then the nut seat drives the third slider to move on the linear slide rail, and then drives the glue dispensing component 2 to move.

[0046] Based on the above implementation, in a specific implementation, as Figures 2 to 4 As shown, the first adjustment component 3 also includes a mounting plate 303, which is connected to the adjustment end of the linear slide module 302; the dispensing component 2 is arranged on the mounting plate 303; a detection part 304 for detecting the moving distance of the dispensing component 2 is provided on the top of the mounting plate 303, and the detection part 304 is located above the displacement detection part 4.

[0047] It should be noted that the detection end of the displacement detection member 4 faces the detection portion 304 .

[0048] In this embodiment, the adjustment end of the linear slide module 302 is connected to the glue dispensing component 2 through the mounting plate 303 to improve the mounting strength. At the same time, a detection part 304 is set on the mounting plate 303 corresponding to the displacement detection part 4, which is convenient for cooperating with the displacement detection part 4 to detect the adjustment distance of the linear slide module 302 to the glue dispensing component 2.

[0049] Based on the above implementation, in a specific implementation, as Figures 2 to 4 As shown, a first screw 305 is penetrated through the detection part 304 along the vertical direction, the first screw 305 is threadedly connected to the detection part 304, and the bottom of the first screw 305 corresponds to the detection end of the displacement detection member 4 in the vertical direction.

[0050] It should be noted that the bottom of the first screw 305 is located correspondingly above the detection end of the displacement detection member 4 .

[0051] In this embodiment, the first screw 305 is adjusted in cooperation with the displacement detecting member 4. The first screw 305 can be rotated on the detecting portion 304 to change the distance between the bottom of the first screw 305 and the detecting end of the displacement detecting member 4, thereby changing the detection range and improving flexibility. The adjustment adaptability range can be changed by the first screw 305 according to actual needs.

[0052] Based on the above implementation, in a specific implementation, as Figures 2 to 4 As shown, the first adjustment component 3 also includes a limit plate 306 and a second screw 307. The limit plate 306 is arranged on the top of the mounting plate 303. The second screw 307 is vertically penetrated on the limit plate 306, and the second screw 307 is threadedly connected to the limit plate 306. The second screw 307 is located above the linear slide module 302, and is suitable for abutting and limiting with the fixed end of the linear slide module 302 after the mounting plate 303 moves downward a preset distance.

[0053] It should be noted that the second screw 307 is correspondingly located above the fixed end of the linear slide module 302 .

[0054] In this embodiment, a limit plate 306 and a second screw 307 are provided on the mounting plate 303. When the adjusting end of the linear slide module 302 drives the mounting plate 303 to move downward a preset distance, the mounting plate 303 simultaneously drives the limit plate 306 and the second screw 307 to move. After moving the preset distance, the bottom of the second screw 307 abuts against the linear slide module 302 to limit the position, thereby preventing the mounting plate 303 from moving too far and causing the dispensing component 2 to contact the substrate, or causing the detection part 304 to move too far and damage the displacement detection part 4. At the same time, the second screw 307 has a certain buffering effect when abutting, thereby preventing damage to the linear slide module 302 and improving the service life.

[0055] Based on the above implementation, in a specific implementation, as Figure 4 As shown, the glue dispensing component 2 is connected to the adjustment end of the first adjustment component 3 through the second adjustment component 5, and the second adjustment component 5 is arranged at the adjustment end of the first adjustment component 3; the glue dispensing component 2 is connected to the adjustment end of the second adjustment component 5, and is suitable for being driven by the second adjustment component 5 to reciprocate in the horizontal direction.

[0056] It should be noted that the adjustment direction of the second adjustment component 5 is consistent with the arrangement direction of the glue dispensing mechanism, that is, it is arranged along the width direction of the substrate.

[0057] In this embodiment, the glue dispensing component 2 is connected to the first adjusting component 3 through the second adjusting component 5, so that each glue dispensing component 2 can be horizontally adjusted through the second adjusting component 5, and the spacing between each glue dispensing component 2 can be adjusted individually. The coating position of the insulating glue is changed accordingly with the change of the coating, thereby improving the adjustment ability and flexibility, so that each glue dispensing component 2 can be accurately coated to the corresponding position on the substrate, thereby improving the adjustment accuracy.

[0058] Based on the above implementation, in a specific implementation, as Figure 4 As shown, the second adjustment component 5 includes a second driving member 501, a fixed plate 502 and a first slider 503; the fixed plate 502 is arranged at the adjustment end of the first adjustment component 3, and the first slider 503 is horizontally slidably connected to the fixed plate 502; the second driving member 501 is arranged on the fixed plate 502, suitable for driving the first slider 503 to slide reciprocatingly in the horizontal direction; the dispensing component 2 is arranged on the first slider 503.

[0059] In this embodiment, the first slider 503 is driven by the second driving member 501 to slide in the horizontal direction on the fixed plate 502, and then the dispensing component 2 is adjusted horizontally to change the spacing between each dispensing component 2, and the coating position of the insulating glue is changed accordingly with the change of the coating, so that each dispensing component 2 can be accurately coated at the corresponding position on the substrate, thereby improving the adjustment accuracy.

[0060] Specifically, this embodiment does not limit the specific structure of the second driving member 501. The second driving member 501 is preferably a differential head, which is arranged on the fixed plate 502. The adjustment end of the differential head is connected to the first slider 503. The adjustment is performed through the differential head to improve the adjustment accuracy. The second driving member 501 can also be a cylinder, a hydraulic cylinder or a linear motor, etc., which can be selected according to actual conditions.

[0061] Specifically, Figure 4 As shown, the fixing plate 502 is arranged on the mounting plate 303, so that the mounting plate 303 can drive the dispensing assembly 2 to adjust in the vertical direction.

[0062] On the basis of the above implementation, in a specific implementation, the displacement detection element 4 is an LVDT displacement sensor.

[0063] In this embodiment, the displacement detection component 4 is an LVDT displacement sensor, which detects the moving distance of the dispensing component 2 and provides real-time feedback through the LVDT displacement sensor, thereby improving the accuracy of adjustment.

[0064] Specifically, the LVDT displacement sensor is arranged at the fixed end of the linear slide module 302, and the detection end of the LVDT displacement sensor corresponds to the bottom of the first screw 305. When the first screw 305 drops to a preset distance, it abuts against the detection end of the LVDT displacement sensor, and detects the moving distance of the dispensing component 2 in real time within a preset range, thereby obtaining the dispensing distance between the dispensing component 2 and the substrate.

[0065] As a convertible embodiment, the displacement detection element 4 may be a photoelectric displacement sensor or a digital laser displacement sensor.

[0066] Based on the above implementation, in a specific implementation, as Figure 1 As shown, a material receiving trough 6 is horizontally provided on the support frame 1, and the material receiving trough 6 is slidably connected to the support frame 1 along the feeding direction of the substrate; the material receiving trough 6 has a material receiving state of sliding to the bottom of the dispensing mechanism, and a dispensing state of sliding to the dispensing mechanism staggered.

[0067] It should be noted that the material receiving groove 6 is arranged below the glue dispensing mechanism, and the material receiving groove 6 is arranged along the same direction as the glue dispensing mechanism, that is, along the width direction of the substrate.

[0068] In this embodiment, a material receiving trough 6 is provided, and after the glue dispensing is completed, the material receiving trough 6 is slid to the material receiving state, so that the material receiving trough 6 is located below the glue dispensing mechanism to collect the remaining insulating glue, thereby preventing the glue dispensing component 2 from missing the insulating glue on the substrate and affecting the coating effect; when glue dispensing is required, the material receiving trough 6 can be moved to the glue dispensing state to avoid affecting the glue dispensing component 2 from coating the insulating glue on the substrate.

[0069] Based on the above implementation, in a specific implementation, as Figure 5 As shown, the dispensing device also includes a third driving member 7, which is arranged on the support frame 1; a guide rail 9 is provided on the support frame 1 in the horizontal direction, and each group of dispensing mechanisms is slidably connected to the guide rail 9 through a second slider 10; each group of dispensing mechanisms is connected to the output shaft of the third driving member 7, and is suitable for being driven by the output shaft of the third driving member 7 to reciprocate horizontally.

[0070] In this embodiment, the third driving member 7 can be used to adjust the lateral displacement of all dispensing mechanisms in the horizontal direction as a whole, so as to adjust the coating position of the insulating glue to follow the displacement of the coating, which is convenient for adjustment and improves the adjustment capability.

[0071] Specifically, the present embodiment does not limit the specific structure of the third driving member 7. The third driving member 7 is preferably an electric cylinder. The third driving member 7 may also be a hydraulic cylinder or a pneumatic cylinder.

[0072] Specifically, the first adjusting assembly 3 is connected to the second sliding block 10 .

[0073] Based on the above implementation, in a specific implementation, as Figures 6 to 10 As shown, the dispensing assembly 2 includes a dispensing valve 201, a connecting block 202, a locking nut 203 and a dispensing head 204; the dispensing valve 201 is connected to the regulating end of the first regulating assembly 3; the connecting block 202 is connected to the liquid outlet end of the dispensing valve 201, and a first through hole communicating with the dispensing valve 201 is provided in the connecting block 202; the end of the connecting block 202 away from the dispensing valve 201 is provided with a first connecting portion 206 and a second connecting portion 207 in sequence along its axial direction, and the diameter of the first connecting portion 206 is larger than that of the second connecting portion 207. The diameter of the second connecting part 207; the dispensing head 204 can be slidably mounted on the second connecting part 207, and a discharge port 205 is provided at the end of the dispensing head 204 away from the connecting block 202, and the discharge port 205 is connected to the first through hole; a limiting part 208 is provided on the peripheral side of the end of the dispensing head 204 close to the connecting block 202; the locking nut 203 passes through the dispensing head 204 and is threadedly connected to the first connecting part 206, which is suitable for locking the limiting part 208 between the locking nut 203 and the first connecting part 206.

[0074] In this embodiment, the dispensing valve 201 can be used to connect an external feeding device, and the start or stop of the delivery of the insulating glue can be controlled. When the dispensing valve 201 is opened, the insulating glue flows from the dispensing valve 201 to the first through hole on the connecting block 202 and then flows out through the discharge port 205 of the dispensing head 204, and then is coated on the substrate; when installing the dispensing head 204, the dispensing head 204 can be sleeved on the second connecting portion 207, and then the locking nut 203 is passed through the dispensing head 204 and tightened on the second connecting portion 207, so that the locking nut 203 clamps the limiting portion 208 on the dispensing head 204 between the locking nut 203 and the second connecting portion 207 for fixing, so as to prevent the locking nut 203 from being removed when disassembly is required. The installation and disassembly method is very convenient, which is convenient for maintenance and faster replacement of the dispensing head 204. Dispensing heads 204 of different specifications can be selected according to different process requirements to achieve customized dispensing.

[0075] Specifically, Figure 6 As shown, a locking portion is provided at one end of the locking nut 203 away from the dispensing valve 201, and a second through hole is adapted to be opened on the locking portion for the dispensing head 204 to pass through. After the locking nut 203 passes through the dispensing head 204 through the second through hole, the limiting portion 208 can be clamped by the locking portion.

[0076] Specifically, Figure 6 As shown, the connecting block 202 is connected to the dispensing valve 201 by screws, which is convenient for installation and disassembly.

[0077] Specifically, Figure 8 As shown, the discharge port 205 is a flat groove structure, which is convenient for coating and forming an insulating layer on the substrate.

[0078] Specifically, Figure 6 and Figure 7 As shown, a limiting groove 209 is recessed at one end of the dispensing head 204 close to the connecting block 202, and a limiting protrusion adapted to the limiting groove 209 is provided at one end of the second connecting part 207 close to the dispensing head 204, which is suitable for limiting the dispensing head 204 to rotate along its axis through the limiting protrusion to avoid affecting the coating effect.

[0079] Specifically, Figure 1 As shown, the glue dispensing device also includes a support roller 8, which is arranged on the support frame 1 along the width direction of the base groove, and the support roller 8 is located below the glue dispensing mechanism, suitable for supporting the substrate and improving the smoothness of the substrate transportation.

[0080] Specifically, Figure 1 As shown, the material receiving trough 6 is located between the support roller 8 and the glue dispensing mechanism.

[0081] Specifically, the dispensing device further includes a controller, and the displacement detection member 4 and the first adjustment component 3 are both connected to the controller in communication. The controller collects the moving distance of the dispensing component 2 in real time, so as to accurately control the first adjustment component 3 and improve the adjustment accuracy.

[0082] The specific working principle of the glue dispensing device provided in this embodiment is as follows: when it is necessary to apply insulating glue to the substrate, the glue dispensing mechanism can be arranged above the substrate along the width direction of the substrate, and the substrate is conveyed through the material receiving trough 6 and the support roller 8 and supported by the support roller 8. The distance between the glue dispensing component 2 and the substrate, that is, the distance between the discharge end of the glue dispensing component 2 and the substrate can be adjusted by the first driving component 301. The first driving component 301 can detect the moving distance of the glue dispensing component 2 in real time through the displacement detection component 4, and according to the preset distance and the moving distance fed back in real time, drive the adjustment end of the linear slide module 302 to adjust the glue dispensing distance between the glue dispensing component 2 and the substrate, stop after adjusting the glue dispensing component 2 to the appropriate position, and connect to the external feeding equipment through the glue dispensing valve 201 to apply the insulating glue to the substrate through the glue dispensing head 204. On the material, it is convenient to accurately control the distance between the dispensing component 2 and the substrate, improve the adjustment accuracy of the thickness of the insulating glue, and when the lateral position of the coating changes, the third driving member 7 can be used to adjust all the dispensing mechanisms as a whole to follow the coating for offset, or the second driving member 501 can be used to drive each dispensing component 2 to adjust the offset in the horizontal lateral direction to ensure the accuracy of the insulating glue coating position, improve the adjustment accuracy and adjustment flexibility, thereby improving the yield rate of the electrode, and the application range is wider; in addition, the dispensing head 204 is easy to install and disassemble quickly through the locking nut 203, and it is convenient to select different specifications of dispensing heads 204 according to different process requirements to achieve customized dispensing; compared with the built-in dispensing of the coating die head, the dispensing device provided in this embodiment is simple and fast to operate, and more efficient. It solves the technical problem that the existing external dispensing device lacks accuracy when adjusting the dispensing distance, is basically based on the operator's experience and judgment, and cannot feedback the real-time distance, which affects the adjustment accuracy.
