Description

Technical Field

[0001] This invention relates to a glue-filling device and glue-filling process, belonging to the technical field of wire harness processing equipment. Background Technology

[0002] After the sheath assembly process is completed, a glue application process is required to reliably fix the connecting wires to the outer shell, ensuring the overall connection stability and sealing performance of the sheath. The existing process uses manual glue application with a handheld syringe, which has significant technical drawbacks: First, manual glue application relies entirely on the operator's skill in controlling the glue dispensing rhythm and path. Applying glue to a single product is time-consuming, unable to meet the pace requirements of mass production, resulting in low overall glue application efficiency and severely restricting production line capacity improvement. Second, manual operation makes it difficult to accurately control the glue amount applied in a single application. The glue dispensing amount varies significantly between different operators, and even among the same operator at different times, resulting in extremely poor consistency. Insufficient glue can lead to insecure fixing of the connecting wires to the outer shell, making them prone to loosening under external force. Excessive glue can cause glue to overflow, contaminating the sheath surface or seep into the connecting wire core, posing a short circuit risk. Ultimately, this leads to a high defect rate, increasing production costs and rework losses.

[0003] Meanwhile, multiple connecting wires inside the sheath are arranged side by side through the pre-reserved through holes in the outer shell. The existing glue application process can only inject glue from one side of the connecting wires. However, the currently used fixing glue has poor fluidity, high viscosity, and weak diffusion ability. The glue injected on one side cannot fully penetrate to the other side along the gap between the connecting wires and the inner wall of the outer shell. This results in multiple glue layer gaps in the fit between the connecting wires and the outer shell, making it impossible to form a full-circumference sealed fixing structure. This not only reduces the reliability of the connection, but also makes it easy for external dust and moisture to enter the interior of the sheath through the gaps, affecting the electrical performance and service life of the connecting wires. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a glue-applying device and glue-applying process that can apply glue to different sides of the connecting wire, with good glue-applying quality, good glue-applying consistency and high glue-applying efficiency.

[0023] In view of the shortcomings of the prior art, the inventors of this invention, through long-term research and extensive practice, have proposed the technical solution of this invention. The following will further explain and illustrate this technical solution, its implementation process, and its principles.

[0024] like Figure 1 As shown, one aspect of this invention discloses a dispensing device, which includes a fixture 1, a dispensing assembly 2, an air valve, and a drive assembly 9. The fixture 1 is at least used to fix the product to be dispensed with glue; in this application, the product to be dispensed with glue is a sheath. Specifically, as shown... Figure 2As shown, the tooling 1 includes a fixing plate 101, on which a fixing groove 102 and a fixing hole 103 are provided. At least one fixing groove 102 and one fixing hole 103 are provided. The fixing groove 102 and the fixing hole 103 are positioned correspondingly. The fixing groove 102 is semi-circular in shape. The wire harness on the sheath is placed in the fixing groove 102, and the outer shell of the sheath is suspended above the fixing groove 102 to fix the vertical position of the sheath. A cylinder is provided on the sheath. When fixing the sheath, the cylinder is fixed inside the cylinder to fix the horizontal position of the sheath. A clamping plate is provided on one side of the fixing plate 101. The clamping plate is provided with a clamping groove. The clamping groove is positioned corresponding to the fixing hole 103. The product is fixed on the fixing plate 101 by the clamping plate. The clamping groove can fix the front and back position of the sheath. Under the action of the fixing groove 102, the fixing hole 103 and the clamping groove, the vertical position, front and back position and horizontal position of the sheath can be fixed, so that the glue application position is consistent.

[0025] The fixing plate 101 is provided with a plurality of fixing grooves 102 and fixing holes 103. The number of fixing grooves 102 and fixing holes 103 is set according to the number of sheaths to be fixed. In this embodiment, there are five fixing grooves 102 and five fixing holes 103.

[0026] The potting assembly 2 is used at least for potting adhesive into the product, such as... Figure 4 As shown, the glue-pouring assembly 2 includes a first glue tube 201, a second glue tube 202, and a mixing glue tube 203. The first glue tube 201 and the second glue tube 202 are respectively connected to the mixing glue tube 203, so that the glue in the first glue tube 201 and the glue in the second glue tube 202 both flow into the mixing glue tube 203. More specifically, the first glue tube 201 and the second glue tube 202 are connected to the mixing glue tube 203 through a connecting block, and the glue in the first glue tube 201 and the glue in the second glue tube 202 flows into the mixing glue tube 203 through the connecting block. The mixing glue tube 203 is at least used to mix the glue flowing out from the first glue tube 201 and the second glue tube 202. Specifically, the mixing glue tube 203 is provided with a threaded rod, and the threaded rod is at least used to stir the mixed glue. The end of the mixing glue tube 203 away from the first glue tube 201 and the second glue tube 202 is connected to a glue discharge head, and the glue flows out through the glue discharge head.

[0027] The air valve includes a first air valve 3 disposed on the first hose 201 and a second air valve 4 disposed on the second hose 202. The first air valve 3 is used at least to control the opening and closing of the first hose 201 to control the amount of adhesive dispensed from the first hose 201 at one time; the second air valve 4 is used at least to control the opening and closing of the second hose 202 to control the amount of adhesive dispensed from the second hose 202 at one time.

[0028] The drive component 9 is disposed on one side of the dispensing component 2. The drive component 9 is used at least to drive the dispensing head to move up and down, left and right, and forward and backward, so that the dispensing head dispenses glue at different positions on the product. The drive component 9 may include a robot, such as... Figure 3 As shown, it may also include a vertical moving component 901, a horizontal moving component 902, and a front-back moving component 903. The vertical moving component 901 is at least used to drive the dispensing head to move up and down; the horizontal moving component 902 is at least used to drive the dispensing head to move left and right; and the front-back moving component 903 is at least used to drive the dispensing head to move back and forth. Under the drive of the vertical moving component 901, the horizontal moving component 902, and the front-back moving component 903, the dispensing head moves to different positions on the product. The vertical moving component 901, the horizontal moving component 902, and the front-back moving component 903 may include cylinders or servo modules. In this embodiment, the vertical moving component 901, the horizontal moving component 902, and the front-back moving component 903 all include servo modules.

[0029] In some implementation cases, when the dispensing device is shut down and reused, the glue will solidify inside the mixing tube 203 and become unusable, requiring the mixing tube 203 to be replaced. Therefore, the mixing tube 203 and the connecting block are designed to be detachably connected.

[0030] In some implementation examples, the first hose 201 is connected to a first glue container 6 via a first connecting pipe 5. The first glue container 6 is pressurized, and under the action of the pressure, the glue in the first glue container 6 flows into the first hose 201 through the first connecting pipe 5. The second hose 202 is connected to a second glue container 8 via a second connecting pipe 7. The second glue container 8 is pressurized, and under the action of the pressure, the glue in the second glue container 8 flows into the second hose 202 through the second connecting pipe 7.

[0031] In some implementations, the dispensing device further includes a fixing frame 12, on which a base 13 is mounted, and the fixing plate 101 is detachably connected to the base 13. Specifically, the base 13 is provided with a plurality of positioning blocks 14, the shape of which is similar to the shape of the bottom of the positioning base 13.

[0032] Another aspect of the present invention discloses a dispensing process based on a dispensing device, the dispensing process comprising the following steps: S1. Fix the product to be glued onto the fixture, and then fix the fixture onto the base; S2. The glue in the first glue bucket flows into the first connecting pipe under pressure; the first air valve opens, allowing the glue to flow from the first connecting pipe into the first glue tube, and then through the connecting block into the mixing glue tube; the glue in the second glue bucket flows into the second connecting pipe under pressure; the second air valve opens, allowing the glue to flow from the second connecting pipe into the second glue tube, and then through the connecting block into the mixing glue tube. S3. Stir the mixed adhesive with the threaded rod inside the mixing tube to mix the two adhesives evenly. S4. Drive the mixing tube to move using the drive assembly, and apply adhesive to different positions on the product.

[0033] Based on the above, when there are multiple products to be glued on the tooling; after the glue is applied to one product, the driving component drives the mixing tube to move to another product and apply glue at a different position on the other product.

[0034] In some implementations, the first glue container is filled with a curing agent, and the second glue container is filled with resin. Specifically, the ratio of the amount of glue dispensed in one go from the first glue tube to the amount dispensed in one go from the second glue tube is 1:1. In this implementation, if the ratio of the amount of glue dispensed from the two glue tubes is not 1:1, the mixed glue will not cure.

[0035] More specifically, the amount of glue discharged in one go by the first tubing and the amount of glue discharged in one go by the second tubing are both 0.55g.

[0036] In some implementation cases, the dispensing interval of the dispensing head is 1 minute.

[0037] In some implementation cases, the dispensing head dispensing glue takes 2 seconds each time.

[0038] It should be understood that the above embodiments are merely illustrative of the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
