Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery dispensing, in particular to a dispensing device. Background Art

[0002] During the lithium battery manufacturing process, in order to protect the laser weld mark of the adapter from being oxidized and blackened after being soaked in electrolyte, and to prevent the welding slag at the weld mark from falling into the core after the core is closed, glue is applied to the weld mark after welding. The currently more commonly used glue dispensing device mainly dispenses the glue in the main body of the glue head at the location where glue is needed. This simple glue dispensing device cannot accurately control the amount of glue dispensed. If too little glue is dispensed, it cannot play a role in protecting the adapter. If too much glue is dispensed, on the one hand, it will increase the cost. On the other hand, if the glue at multiple points flows to the position where the cover plate and the aluminum shell meet, it is easy to form a hot spot defect during the subsequent laser full welding process, causing the battery to be scrapped. In addition, the flow state of the colloid during the glue dispensing process is easily affected by the ambient temperature, which restricts the glue dispensing process and greatly reduces the glue dispensing effect.

The lower end of the adjusting bolt 2 abuts against the top of the first spring 3. The adjusting bolt 2 has an external thread, and the lower end is tightened in the receiving groove. The nut 1 is screwed on the upper end of the adjusting bolt 2 and at the top end of the upper cover 5. The function of the nut 1 is to prevent dust from entering the interior of the upper cover 5, causing the adjusting bolt 2 to be stuck in the upper cover 5, and the dispensing device cannot be repaired.

[0024] The main body 7 is provided with a through hole, into which a striker 6 is embedded. A second spring 9 is provided below the striker 6, and the second spring 9 is sleeved around the lower end of the striker 6. The lower cover 11 has through holes at four corners, and internal threaded holes are provided at the lower end of the main body 7 corresponding to the through holes. Four screws 12 are screwed from the bottom through the through holes of the lower cover 11 into the internal threaded holes at the lower end of the main body 7, thereby securing the lower cover 11 to the main body 7. An O-ring is provided at the connection between the second spring 9 and the lower cover 11 to improve the sealing of the connection. The lower cover 11 has an external thread at the bottom end, and the nozzle 13 has an internal threaded hole.

In this embodiment, springs are provided above and below the striker 6, allowing the striker 6 to move up and down the main body 7, carrying the glue liquid from the nozzle 13.

[0025] A rear seat 15 is provided on the side of the main body 7, and the rear seat 15 is used to receive the glue. Two through holes are provided at the waist of the main body 7, and two internal threaded holes are provided in the rear seat 15 corresponding to the through holes. Two screws 8 are passed through the through holes at the waist of the main body 7 and screwed into the internal threaded holes of the rear seat 15, thereby fixing the main body 7 and the rear seat 15. After the two screws 8 pass through the through holes at the waist of the main body 7, two O-rings 18 are inserted into the internal threaded holes of the rear seat 15 to improve the sealing of the connection.

[0026] The bottom of the rear seat 15 is provided with two transverse through holes for placing two heating rods 17. The heating rods 17 are electric heating rods that can be heated when powered on. In this embodiment, the glue received by the rear seat 15 is heated by the heating rods 17, thereby preventing the glue from solidifying and ensuring that the glue maintains sufficient fluidity.

[0027] The rear seat 15 is further provided with a glue liquid port 21 , which is located in the middle of the connection portion between the rear seat 15 and the main body 7 . The function of the glue liquid port 21 is to allow the glue liquid heated by the rear seat 15 to flow into the main body 7 .

[0028] The rear seat 15 is also provided with a sheet metal part 19, which is used to be mounted on the outside of the rear seat 15. The sheet metal part 19 includes a front sheet metal, an upper sheet metal, and left and right sheet metals. The two sides of the front sheet metal are respectively connected to the left and right sheet metals. The tops of the front sheet metal and the left and right sheet metals are connected to the three sides of the upper sheet metal to form a hollow sheet metal part 19. The width of the upper sheet metal is half of the width of the left and right sheet metals. The purpose is to expose the upper part of the rear seat 15 for connecting the connecting rod 14.

[0029] The left and right sheet metals are of the same size and shape, and are provided with U-shaped grooves at corresponding positions on both sides. The rear seat 15 is provided with an internal threaded hole corresponding to the U-shaped groove of the sheet metal 19. Two screws 16 are passed through the U-shaped groove of the sheet metal 19 and screwed into the internal threaded hole of the rear seat 15, thereby fixing the sheet metal 19 on the rear seat 15 to prevent dust from entering the rear seat 15 and causing glue contamination.

[0030] The connecting rod 14 has external threads at both ends and an internal threaded hole corresponding to the top of the rear seat 15. The connecting rod 14 is vertically connected to the rear seat 15, and one end of the connecting rod 14 is screwed into the internal thread at the top of the rear seat 15, thereby connecting the connecting rod 14 to the rear seat 15.

[0031] The feeder 20 is provided with a feeding port (not shown in the figure), which is located at the right end of the bottom of the feeder 20. The bottom of the feeder 20 is provided with an internal threaded hole, and the other end of the connecting rod 14 is screwed into the internal threaded hole at the bottom of the feeder 20, thereby fixing the connecting rod 14 to the feeder 20.

[0032] The glue in this embodiment enters from the feeding port and flows into the connecting rod 14 along the internal threaded hole at the bottom end of the feeder 20, then flows into the back seat 15 through the connecting rod 14, and is heated by the heating rod 17, and then flows into the lower cover 11 of the main body 7 through the glue port 21 of the back seat 15. The glue is sprayed out through the nozzle 13 by the up and down movement of the striker 6.

[0033] This embodiment can heat the glue by arranging a heating rod 17 in the rear seat 15 to prevent the glue from solidifying, thereby ensuring that the glue always maintains sufficient fluidity. Therefore, when using the dispensing device, the influence of the surrounding temperature can be ignored, so that the dispensing work remains orderly and is not restricted by the working environment.

[0034] Example 2

[0035] This embodiment provides a dispensing device. The difference between this embodiment and Example 1 is that the dispensing device also includes a solenoid valve, which is arranged between the feeding port of the feeder 20 and the internal threaded hole at the bottom end. One end of the solenoid valve is connected to the feeding port, and the other end is connected to the connecting rod 14. The solenoid valve is used to control the liquid flowing into the rear seat 15, thereby controlling the dispensing amount, and will not cause more or less dispensing.

[0036] This embodiment uses a solenoid valve to add glue through the feeder 20. This embodiment uses the solenoid valve to control the flow of glue into the rear seat 15, thereby achieving precise control of the glue dispensing amount and preventing the occurrence of more or less glue during dispensing. This embodiment achieves precise control of the glue dispensing amount by controlling the length of time the solenoid valve is open and the pressure of the material supply, thereby preventing the occurrence of more or less glue during dispensing.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
