Description

Technical Field

[0001] This utility model relates to the technical field of vehicle ignition coils, and more particularly to a vehicle ignition coil lead wire dispensing mechanism. Background Technology

[0002] Currently, the existing production process for dispensing automotive ignition coil leads consists of the following steps: wire winding, soldering, manual dispensing, manual visual inspection, testing, and finally packaging. The drawbacks of this existing process are that the dispensing operation requires the adhesive dots to cover the coil leads and has specific requirements for the thickness and spacing of the dots, making it prone to defects. It also demands a high level of operator skill, requiring extensive training before operators can be trained, resulting in poor quality stability and difficulty in mastering the process manually. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a dispensing mechanism for automotive ignition coil leads. This mechanism can automatically complete the dispensing of coil leads in one go, replacing manual operation, thereby improving production efficiency, reducing the number of workers and labor intensity, and lowering the defect rate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A dispensing mechanism for automotive ignition coil leads includes a coil positioning and rotation mechanism connected to a robotic vision controller, an automatic dispensing mechanism, and an automatic CCD appearance mechanism; wherein... The coil positioning and rotation mechanism includes a rotating shaft driven by a rotary cylinder, and a first coil fixing fixture and a second coil fixing fixture fixedly mounted on the rotating shaft; the robot vision controller controls the rotary cylinder to rotate the first coil fixing fixture on which the first coil product is placed, and the second coil fixing fixture on which the second coil product is placed. An automatic dispensing mechanism includes a first robotic arm connected to a robotic vision controller and a dispensing controller, and a glue tube mounted on the first robotic arm and connected to the dispensing controller. An automated CCD appearance mechanism includes a second robotic arm connected to a robotic vision controller and a CCD camera mounted on the second robotic arm.

[0005] As described above, in an automatic dispensing mechanism for automotive ignition coil leads, the rotary cylinder has a rotation angle of 45° to -45° and a rotation angle of -45° to 45° when performing the dispensing operation; when the dispensing points of the coil leads on the first coil product and the second coil product pass the inspection by a CCD camera, the rotary cylinder has a rotation angle of 45° to -45°.

[0006] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: Firstly, this utility model is applied to the dispensing mechanism for automotive ignition coil leads. Through the coil positioning and rotation mechanism, the position of the coil product is fixed and the dispensing point of the coil lead is changed; through the automatic dispensing mechanism, quantitative positioning dispensing of the coil lead is achieved; and through the automatic CCD appearance mechanism, the dispensing points on the coil product are detected and judged, reducing the number of workers and labor intensity, and lowering the production defect rate.

[0007] Secondly, this utility model applies to the dispensing mechanism for automotive ignition coil leads. During the dispensing process, a rotary cylinder rotates at angles of 45° to -45° and -45° to 45° to first dispense adhesive onto one side of the coil lead, then onto the other side. Finally, a robotic arm's vision computer uses images from a CCD camera to determine the dispensing points on the coil lead, and the rotary cylinder resets qualified products by rotating them 45° to -45°. In other words, the production steps for automotive ignition coil lead dispensing are changed to: winding, soldering, automatic dispensing, CCD inspection, manual inspection, testing, and finally packaging, replacing manual labor and significantly improving production efficiency.

[0014] Now combined Figures 1 to 5 As shown, this utility model is applied to a dispensing mechanism for automotive ignition coil leads, including a coil positioning and rotation mechanism 100 connected to a robotic vision controller (chip model GX8-C552S), an automatic dispensing mechanism 200, and an automatic CCD appearance mechanism 300. Please combine Figures 3 to 5As shown, the coil positioning and rotation mechanism 100 of this utility model includes a rotary cylinder 110, a rotating shaft 120, a rotating shaft fixing seat 130, a coil fixing fixture 140, and a base plate 150. The coil fixing fixture 140 is fixedly mounted on the rotating shaft 120, which is assembled between the rotating shaft fixing seat 130 and the rotary cylinder 110. The rotating shaft fixing seat 130 and the rotary cylinder 110 are fixed on the base plate 150. The robot vision controller controls the rotary cylinder 110 to rotate the coil fixing fixture 140 by air pressure. The coil fixing fixture 140 includes a first coil fixing fixture 141 and a second coil fixing fixture 142. A first coil product 400 is placed on the first coil fixing fixture 141, and a second coil product 500 is placed on the second coil fixing fixture 142.

[0015] Please combine Figure 1 and Figure 2 As shown, the automatic dispensing mechanism 200 of this utility model includes a glue cartridge fixing bracket 220, a glue cartridge 230, a first robotic arm 210 connected to a robotic vision controller, and a dispensing controller 240. The dispensing controller 240, connected to the robotic vision controller, is connected to the glue cartridge 230 to control the dispensing amount. The glue cartridge 230 is placed on the glue cartridge fixing bracket 220, which is mounted on the first robotic arm 210. The first robotic arm 210 performs quantitative dispensing at designated positions by moving. Both the first robotic arm 210 and the second robotic arm 210 are robotic arms from the LS-B series robotic arm. When the automatic dispensing mechanism 200 performs dispensing operations, the rotary cylinder 110 has a rotation angle of 45° to -45° and a rotation angle of -45° to 45°.

[0016] Please combine Figure 1 and Figure 2 As shown, the automatic CCD appearance mechanism 300 of this utility model includes a second robotic arm 310 connected to a robotic vision controller and a CCD camera 320, and also includes a CCD camera mounting bracket 330. The CCD camera connected to the robotic vision controller is mounted on the CCD camera mounting bracket 330, which is mounted on the second robotic arm 310. The robotic vision computer detects the glue dots on the coil leads by the image transmitted from the CCD camera to check whether they are qualified. When the glue dots on the coil leads of the first coil product 400 and the second coil product 500, which have been glued by the automatic glue dispensing mechanism 200, are detected as qualified by the CCD camera 320, the rotary cylinder 110 has a rotation angle of 45° to -45°.

[0017] Specifically, when this utility model is applied to the dispensing operation of an automotive ignition coil lead dispensing mechanism, the robotic arm vision controller controls the dispensing of the first coil product 400 and the second coil product 500. The specific control steps are as follows: Step 1: The first coil product 400 and the second coil product 500 are placed on the first coil fixing fixture 141 and the second coil fixing fixture 142, respectively. Step 2: The rotary cylinder 110 controls the rotating shaft 120 to rotate 90°, so that the first coil fixing fixture 141 and the second coil fixing fixture 142 rotate synchronously from a -45° angle to a 45° angle. Step 3: The first robotic arm 210 moves to the first glue dispensing starting point of the first coil product 400, and then the first robotic arm 210 descends to perform straight glue dispensing on the left side of the coil lead of the coil product 400, forming a glue dot on the left side of the first coil product. Step four, the first robotic arm 210 rises and moves to the second glue application start point of the second coil product 500, and then the first robotic arm 210 descends to apply glue in a straight line to the left side of the coil lead of the second coil product 500, forming a glue point on the left side of the second coil product. Step 5: After the first robotic arm 210 rises and resets above the second glue application start point of the second coil product 500, the rotary cylinder 110 controls the rotating shaft 120 to rotate 90°, so that the first coil fixing fixture 141 and the second coil fixing fixture 142 simultaneously rotate from a 45° angle to a -45° angle. Step six, the first robotic arm 210 moves to the third glue application start point of the first coil product 400, and then the first robotic arm 210 descends to apply glue in a straight line to the right side of the coil lead of the second coil product 500, forming a glue point on the right side of the second coil product. Step 7: The first robotic arm 210 rises and moves the fourth glue dotting starting point of the first coil product 400, and then the first robotic arm 210 descends to perform straight glue dotting on the right side of the coil lead of the first coil product 400, forming a glue dot on the right side of the first coil product. Step 8: The first robotic arm 210 rises and resets, and the rotary cylinder 110 controls the rotating shaft 120 to rotate 90° so that the first coil fixing fixture 141 and the second coil fixing fixture 142 rotate synchronously from a -45° angle to a 45° angle. Step nine: After the second robotic arm 310 drives the CCD camera 320 to detect the glue dots on the left and right sides of the first coil product 400 and the glue dots on the left and right sides of the second coil product 500, the second robotic arm 310 returns to its original position. Step 10: If the adhesive dots on the left and right sides of the first coil product, the left and right sides of the second coil product, and the right sides of the second coil product pass the inspection by the CCD camera 320, then the rotary cylinder 110 controls the rotating shaft 120 to rotate 90°, so that the first coil fixing fixture 141 and the second coil fixing fixture 142 simultaneously rotate from a 45° angle to a -45° angle; if the adhesive dots on the left and right sides of the first coil product, the left and right sides of the second coil product, and the right sides of the second coil product fail the inspection by the CCD camera 320, then both the first coil fixing fixture 141 and the second coil fixing fixture 142 remain at a 45° angle.
