Referring to fig. 1, fig. 1 is a schematic axial view illustrating an overall dispensing device according to an embodiment of the present invention, which includes a fixing jig 100, a rotary driving member 200, and a dispensing mechanism 300. Referring to fig. 2 and 3, the fixing jig 100 is used for bearing the workpiece 600, and the rotary driving member 200 can drive the fixing jig 100 to rotate, so that the workpiece 600 borne by the fixing jig 100 can rotate along with the fixing jig 100, and the glue dispensing mechanism 300 can provide glue to the workpiece 600, so that the workpiece 600 can be dispensed in a rotating manner, and the workpiece 600 can be dispensed more uniformly.

Referring to fig. 2, in one embodiment, the dispensing apparatus further includes a fixing frame 400, the fixing frame 400 includes a top plate 410, a bottom plate 420, and a supporting column 430, the top plate 410 is used for carrying the rotary driving member 200, the supporting column 430 is disposed between the top plate 410 and the bottom plate 420, and the bottom plate 420 can be connected to other structures, for example, a supporting table (not shown) as a processing station, so that the bottom plate 420 is connected to the supporting table, thereby the position of the top plate 410 can be determined by the supporting column 430 disposed between the top plate 410 and the bottom plate 420, and further the relative positions of the rotary driving member 200 disposed on the top plate 410, the fixed fixture 100 connected to the rotary driving member 200, and the workpiece 600 located in the fixed fixture 100 are determined, so that the dispensing mechanism can accurately position the dispensing position.

In this embodiment, one side of the top plate 410 close to the dispensing mechanism 300 is further provided with a waste glue box 440, and when the operation process needs to be stopped midway or the device is debugged, the waste glue box 440 can be used for recovering waste glue sprayed by the dispensing mechanism 300 to prevent the glue from dripping onto the supporting table or the bottom plate 420, thereby influencing the dispensing process and other operations.

Referring to fig. 2 and 3, in one embodiment, the fixing jig 100 is provided with a groove 120 for carrying a workpiece 600. The groove 120 matches the outer shape of the workpiece 600, and thus the positioning accuracy and the fixing reliability of the workpiece 600 can be further ensured. The fixing fixture 100 is further provided with a first channel 110 penetrating through the fixing fixture 100. The workpiece 600 can cover the first channel 110 when placed in the groove 120 of the fixing jig 100. A second channel 210 penetrating through the rotary driving member 200 is arranged in the rotary driving member 200, one end of the first channel 110 far away from the groove 120 is connected with the second channel 210, one end of the second channel 210 far away from the first channel 110 is connected with a vacuum generator (not shown), and the first channel 110 and the second channel 210 are both hollow. The vacuum generator may be disposed on the bottom plate 420 or may be externally connected thereto.

In this embodiment, since the workpiece 600 can cover the first channel 110 when being placed in the groove 120 of the fixing jig 100, negative pressure is formed in the first channel 110 and the second channel 210 by the vacuum generator, and the workpiece 600 can be adsorbed in the groove 120 of the fixing jig 100. In addition, in this embodiment, the vacuum degree formed in the first channel 110 and the second channel 210 by the vacuum generator is reasonably adjusted, so that the workpiece 600 can be stably adsorbed on the fixing jig 100 and synchronously rotate along with the fixing jig 100.

In this embodiment, a vacuum connector 240 is further disposed between the rotary driving member 200 and the vacuum generator (not shown), and one end of the vacuum connector 240 is rotatably connected to one end of the rotary driving member 200 away from the fixing jig 100, so that when one end of the rotary driving member 200 drives the fixing jig 100 to rotate, the other end of the rotary driving member 200 does not rotate the vacuum connector 240. The other end of the vacuum air joint 240 is connected to the vacuum generator, and the vacuum generator generates negative pressure in the first channel 110 and the second vacuum channel 210 through the vacuum air joint 240, so as to attach the workpiece 600 to the groove 120 of the fixing jig 100.

In one embodiment, the groove 120 matches with the shape of the workpiece 600, so that the workpiece 600 can be accurately positioned, the workpiece 600 and the output shaft 220 of the rotary driving member 200 have high coaxiality, that is, the workpiece 600 can more accurately rotate around its own axis, and thus when the workpiece 600 rotates and receives glue, the glue can be more uniformly sprayed on the workpiece 600. The coaxiality is a positioning tolerance, and a theoretically correct positioning position of the workpiece 600 should coincide with a reference axis, which is the axis of the visual output shaft 220 in this embodiment. Since different points of the axis of the workpiece 600 relative to the axis of the output shaft 220 may occur in all directions in space, the tolerance band is a cylinder with the axis of the output shaft 220 as the axis, and the tolerance value is the diameter of the cylinder. In the present embodiment, the workpiece can be accurately positioned by matching the shape of the groove 120 with the workpiece even if the diameter of the cylinder about the axis of the output shaft 220 is small.

Referring to fig. 3, in one embodiment, a stop 230 is further disposed between the output shaft 220 and the fixing jig 100, and the stop 230 can ensure that the fixing jig 100 rotates synchronously with the output shaft 220, i.e. prevent the fixing jig 100 from "slipping" relative to the rotary driving element 200, thereby ensuring uniformity of the rotation speed of the fixing jig 100 and the workpiece 600 on the fixing jig 100. In addition, in order to further ensure the dispensing uniformity of the workpiece 600, the output shaft 220 and the fixing jig 100 are in transition fit, and the fit tolerance of the fit is less than 0.03mm, so that the degree of the rotation of the workpiece 600 around the axis thereof is improved by improving the fit precision between the output shaft 220 and the fixing jig 100. The fitting tolerance refers to a variation amount of an allowable gap or interference, which is equal to the sum of tolerances of a hole and a shaft (structurally similar to the output shaft and the fixing jig in the present embodiment) constituting the fitting.

In one embodiment, the workpiece 600 includes a bottom wall 610 and a sidewall 620 connected to the periphery of the bottom wall 610. In this embodiment, the workpiece 600 may be a positive casing of a button cell. When the button cell is installed, a sealant needs to be dispensed between the positive electrode shell and the negative electrode shell of the button cell so that the positive electrode shell and the negative electrode shell can be bonded and kept sealed, and therefore the performance of the button cell is prevented from being reduced due to electrolyte leakage. If the glue is coated on the bottom wall 610 of the positive electrode shell, firstly, the space surrounded by the positive electrode shell and the negative electrode shell is occupied, so that the overall structure of the button cell is not compact enough, and the space utilization rate of the button cell is damaged; secondly, the glue has viscosity, so that the position of an internal part is difficult to adjust, and the installation difficulty is improved; finally, on the premise that the glue application amount is a fixed amount, the glue is coated on the bottom wall 610 of the positive electrode shell, the amount of the glue coated on the side wall 620 of the positive electrode shell is reduced, and therefore the adhesion between the positive electrode shell and the negative electrode shell cannot be guaranteed, the sealing performance between the positive electrode shell and the negative electrode shell cannot be guaranteed, and the performance of the button cell cannot be guaranteed.

In the above embodiment, the fixing jig 100 is driven to rotate by the rotary driving member 200, and since the workpiece 600 can be vacuum-sucked in the groove 120 of the fixing jig 100, and the groove 120 matches with the shape of the workpiece 600, the workpiece 600 can rotate around the axis of the workpiece 600 with the fixing jig 100. At this time, since the glue dispensing mechanism can spray the glue on the side wall 620 of the workpiece 600, the side wall 620 of the workpiece 600 can uniformly receive the glue sprayed by the glue dispensing mechanism 300 by rotating the workpiece 600 around its own axis.

Referring to fig. 4, in one embodiment, the dispensing mechanism 300 includes a dispensing valve 310, an angle control assembly 320, a first control assembly 330, and a second control assembly 340. The dispensing valve 310 is disposed on the angle control assembly 320, and the angle control assembly 320 is used for controlling the pitch attitude of the dispensing valve 310. The first control assembly 330 is used to adjust the spatial position of the angle control assembly 320. The second control assembly 340 is used to adjust the spatial position of the first control assembly 330. For different dispensing positions of different workpieces 600, the angle control assembly 320 and the dispensing valve 310 can be adjusted to the appropriate dispensing position by the cooperation of the first control assembly 330 and the second control assembly 340. Further, the pitch attitude of the dispensing valve 310 is adjusted by the angle control assembly 320, so that the dispensing valve 310 can accurately spray the glue to a required position on the inner surface of the side wall 620 of the workpiece 600.

Referring to fig. 3 and 4, based on the above embodiment, the rotary driving member 200 drives the fixing jig 100 to rotate synchronously with the workpiece 600, and the angle control assembly 320 and the dispensing valve 310 are adjusted to a proper dispensing position by the first control assembly 330 and the second control assembly 340, and further, the angle control assembly 320 adjusts the pitch attitude of the dispensing valve 310, so that the dispensing valve 310 can accurately spray the glue to a desired position on the inner surface of the sidewall 620 of the workpiece 600. Further, as the dispensing valve 310 sprays glue onto the workpiece 600, the workpiece 600 is rotating, thereby forming an annular "glue ring" on the inner surface of the sidewall 620 of the workpiece 600.

In the above embodiment, since the rotary driving member 200 can drive the workpiece 600 to rotate, after the dispensing valve 310 forms a ring-shaped "glue ring" on the inner surface of the sidewall 620 of the workpiece 600, the "glue ring" is diffused to other positions of the inner surface of the sidewall 620 of the workpiece 600 under the action of the rotating centrifugal force, so that the glue is diffused to other positions of the sidewall 620, and the dispensing of a required area on the inner surface of the sidewall 620 of the workpiece is realized.

In one embodiment, the dispensing valve 310 can control the amount of glue ejected (i.e. the glue discharging amount), that is, the dispensing valve 310 can eject a fixed amount of glue onto the inner surface of the sidewall 620. The rotary driving member 200 is a hollow stepping motor, and can control the fixed jig 100 and the workpiece 600 to rotate at a constant speed. The rotating speed of the hollow stepping motor is adjusted according to the glue discharging amount of the glue dispensing valve 310 and the size of the area, which is required to be covered with the glue, on the inner surface of the side wall 620 of the workpiece 600, so that the glue ring can be spread to the area, which is required to be covered with the glue, on the inner surface of the side wall 620 of the workpiece 600, and finally, the uniform glue dispensing on the inner surface of the side wall 620 of the workpiece 600 is completed. In this embodiment, the glue outlet amount of the glue dispensing valve 310 is adjusted to prevent excessive glue from flowing to the bottom wall 610 of the workpiece 600, and the glue ring is uniformly diffused by adjusting the rotation speed of the hollow stepping motor and rotating the hollow stepping motor at a uniform rotation speed, so as to improve the uniformity of glue dispensing on the inner surface of the sidewall 620 of the workpiece 600. And the glue ring is spread on the inner surface of the side wall 620 of the workpiece 600 in a rotating mode, so that air bubbles in the glue ring can be reduced, and the glue dispensing effect is improved.

Referring to fig. 5 and 6, in one embodiment, the angle control assembly 320 includes a supporting plate 321, an adjusting handle 322, and a supporting frame 323, the supporting plate 321 is used to support the dispensing valve 310, the adjusting handle 322 is disposed on the supporting plate 321, the adjusting handle 322 is used to adjust an angle position of the supporting plate 321, and the supporting frame 323 is used to support the supporting plate 321. The supporting frame 323 is further provided with a sliding groove 324, and the sliding groove 324 can be in sliding fit with the adjusting handle 322. In this embodiment, since the dispensing valve 310 is disposed on the supporting plate 321, the supporting plate 321 is rotatably connected to the supporting frame 323, the angle of the supporting plate 321 rotating relative to the supporting frame 323 can be adjusted by the adjusting handle 322, that is, the pitching posture of the dispensing valve 310 can be adjusted by the adjusting handle 322. Furthermore, angle scales are arranged beside the sliding groove 324, and the position of the adjusting handle 322 can be combined with the angle scales to determine the rotating angle of the bearing plate 321 relative to the support frame 323 due to the sliding fit of the adjusting handle 322 and the sliding groove 324, so that the pitching posture of the dispensing valve 310 can be determined without repeatedly adjusting the angle position of the bearing plate 321 relative to the support frame 323 for workpieces with the same specification, the process is saved, and the production efficiency is improved.

Referring to fig. 5, in one embodiment, the first control assembly 330 includes a first driving member 331, a first base 332, and a first sliding rail 333, and the supporting frame 323 is disposed on the first base 332. The second control assembly 340 includes a second driving member 341, a second base 342, and a second sliding rail 343, and the first sliding rail 333 is disposed on the second base 342. In this embodiment, the first driving element 331 is configured to drive the first base 332 to slide on the first sliding track 333, the supporting frame 323 is disposed on the first base 332, the second driving element 341 is configured to drive the second base 342 to slide on the second sliding track 343, and the first sliding track 333 is disposed on the second base 342.

Referring to fig. 4, in the above embodiment, the supporting frame 323 is disposed on the first base 332, that is, the angle driving assembly and the dispensing valve 310 are disposed on the first base 332, so that the first driving member 331 drives the first base 332 to slide on the first sliding rail 333, the angle driving assembly 320 and the dispensing valve 310 disposed on the first base 332 can move in the Z direction, and further the angle driving assembly 320 and the dispensing valve 310 can reach any position of the first base 332 within the stroke range of the first sliding rail 333 along the Z direction.

Similarly, since the first slide rail 333 is disposed on the second base 342, the second driving member 341 drives the second base 342 to slide on the second slide rail 343, so that the first slide rail 333 disposed on the second base 342, the angle driving assembly 320 disposed on the first base 332, and the dispensing valve 310 can move in the Y direction, and further the angle control assembly 320 and the dispensing valve 310 can reach any position of the second base 342 within the stroke range of the second slide rail 343 in the Y direction. Therefore, the angle control assembly 320 and the dispensing valve 310 can reach any required position within the stroke range of the first slide rail 333 and the second slide rail 343 in the YOZ plane in fig. 4 by the cooperation of the first control assembly 330 and the second control assembly 340.

In addition, in the embodiment, the angle control assembly 320 can adjust the pitch attitude of the dispensing valve 310, and in the embodiment, the dispensing valve 310 can spray a proper amount of glue to the inner surface of the sidewall 620 of the workpiece 600 at a proper dispensing position in a proper dispensing attitude through the cooperation of the angle control assembly 320, the first control assembly 330 and the second control assembly 340, that is, the dispensing valve 310 can be accurately positioned through the cooperation of the angle control assembly 320, the first control assembly 330 and the second control assembly 340, so that the dispensing position is more accurate, and the dispensing accuracy is improved.

Referring to fig. 4, in one embodiment, the second control assembly 340 further includes an abutting member 344, and the abutting member 344 abuts between the second base 342 and the first sliding rail 333. Since the angle control assembly 320 and the dispensing valve 310 are both disposed on the first base 332, and the first base 332 slides on the first sliding rail 333, that is, a component with a certain weight is disposed on the first sliding rail 333, when the second driving member 341 drives the second base 342 to slide along the Y direction while bearing the first sliding rail 333, the first sliding rail 333 may shake relative to the second base 342, thereby reducing the positioning accuracy of the dispensing valve 310. In this embodiment, the abutting part 344 is disposed between the first slide rail 333 and the second base 342, and the abutting part 344 abuts between the first slide rail 333 and the second base 342, so as to improve the connection stability between the first slide rail 333 and the second base 342, thereby preventing the first slide rail 333 from shaking relative to the second base 342, improving the control accuracy of the second control component 340 in the Y direction, and further improving the positioning accuracy of the dispensing valve 310.

In this embodiment, a vacuum generator (not shown) is used to form negative pressure in the first channel 110 and the second channel 210, so as to stably adsorb the positive electrode shell placed in the groove 120 of the fixing jig 100, and the fixing jig 100 is driven to rotate by the rotary driving member 200, because the positive electrode shell is vacuum adsorbed in the groove 120, and the stop member 230 is arranged between the fixing jig 100 and the output shaft 220, the positive electrode shell can synchronously rotate along with the fixing jig 100.

In this embodiment, the second driving member 341 is controlled to slide the second base 342 to a suitable position on the Y axis, and the first driving member 331 is controlled to slide the first base 332 to a suitable position on the Z axis, so as to adjust the angle control assembly 320 to a suitable dispensing position, and then the adjustment handle 322 is moved to adjust the angle that the carrier plate 321 rotates relative to the supporting frame 323, i.e. adjust the pitch attitude of the dispensing valve 310, so that the dispensing valve 310 can align with a suitable dispensing position on the inner surface of the positive casing side wall 620, so as to form a "glue ring" at a suitable height from the bottom wall 610 of the inner surface of the positive casing side wall 620.

Finally, in this embodiment, the positive electrode casing is driven by the rotary driving member 200 to rotate at a constant speed along with the fixing jig 100, so that the glue ring on the inner surface of the side wall 620 of the positive electrode casing is spread to the area of the inner surface of the side wall 620 of the positive electrode casing, which is required to be covered with glue, under the action of the rotary centrifugal force, and the glue dispensing amount of the glue dispensing valve 310 and the rotation speed of the rotary driving member 200 are adjustable, so that the glue ring can be fully spread on the inner surface of the side wall 620 of the positive electrode casing without overflowing the positive electrode casing and splashing out, and can not be spread to the bottom wall 610 of the positive electrode casing to block the installation of other components. In addition, the glue ring is diffused on the inner surface of the side wall 620 of the positive electrode shell in a rotating mode, so that bubbles in the glue ring can be reduced, the sealing performance is prevented from being reduced due to the existence of the bubbles when the positive electrode shell is bonded with the negative electrode shell, or the bubbles are prevented from being broken to generate impact force and push other parts in the button cell due to the extrusion contact between the positive electrode shell and the negative electrode shell when the positive electrode shell is bonded with the negative electrode shell, the positions of the parts are changed, and the performance condition of the button cell is reduced.

Referring to fig. 7, in one embodiment, the dispensing device further includes a drag chain 500 for receiving the wire of the dispensing device, and the wire of the dispensing device is received and sorted by the drag chain 500, so that the wire can be prevented from being twisted and knotted, and the wire to which each component belongs can be identified; on the other hand, the waste glue can be prevented from dropping on scattered electric wires to adhere the electric wires, so that the troubleshooting and the replacement of parts are facilitated.
