Description

Technical Field

[0001] This utility model relates to the field of adhesive spraying tooling technology, and in particular to an adhesive spraying tooling for automotive injection molded parts. Background Technology

[0002] Automobiles are assembled from many injection-molded parts. In the processing of some automotive injection-molded parts, the parts need to be placed in the processing equipment for gluing before the subsequent bonding work can be completed. However, nowadays, after the injection-molded parts are glued, workers need to manually unload them, place the glued parts in the designated position, and then load the parts to be glued. The whole process is cumbersome and reduces the efficiency of gluing the injection-molded parts. Utility Model Content

[0003] This utility model discloses a glue spraying fixture for automotive injection molded parts, which solves the problem that manual unloading is required after the injection molded parts are glued, which is cumbersome and reduces the efficiency of glue spraying on injection molded parts.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A glue spraying fixture for automotive injection molded parts includes a U-shaped fixed frame, two symmetrical L-shaped plates inside the fixed frame, a liftable movable plate on the inner side of the L-shaped plates, and a first electric telescopic rod for driving the movable plate on the L-shaped plates; two symmetrical and liftable second electric telescopic rods on one side of the fixed frame, a support plate and a lifting plate are fixed to the fixed end and telescopic end of the second electric telescopic rods respectively; notches are provided at the bottom of the L-shaped plates and on the movable plate, and the support plate and lifting plate correspond to the notches on the L-shaped plates and the movable plate respectively; a first conveying unit is provided on the fixed frame for driving the second electric telescopic rods away from the fixed frame, and a spray gun is provided inside the fixed frame.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After placing the two sides of the injection molded part on the two L-shaped plates, the first electric telescopic rod can be activated to drive the moving plate downwards, pressing down the top surface of the injection molded part and securing it with the L-shaped plates. Then, the adhesive can be evenly applied to the injection molded part using a spray gun. Once the surface of the injection molded part is processed, the supporting plate and the lifting plate will tighten and fix the injection molded part, allowing the first electric telescopic rod to drive the moving plate to return to its original position. Subsequently, the first conveying unit will drive the second electric telescopic rod to move away from the fixed frame, allowing the supporting plate and the lifting plate to move the injection molded part outside the fixed frame. Then, the two second electric telescopic rods will move downwards to place the injection molded part in the designated position. After the processed injection molded part is removed from the L-shaped plate, the operator can promptly place another injection molded part to be processed. This invention eliminates the need for manual unloading of processed injection molded parts, reducing the workload of the operators and improving the processing efficiency of injection molded parts.

Detailed Implementation

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a glue spraying fixture for automotive injection molded parts, including a U-shaped fixed frame 1. The fixed frame 1 contains two symmetrically arranged L-shaped plates 2. The inner side of each L-shaped plate 2 has a liftable movable plate 21. A first electric telescopic rod 22 for driving the movable plate 21 is provided on the L-shaped plate 2. One side of the fixed frame 1 has two symmetrically arranged and liftable second electric telescopic rods 4. A bearing plate 41 and a lifting plate 42 are fixed to the fixed end and telescopic end of each second electric telescopic rod 4, respectively. Notches are provided at the bottom of the L-shaped plate 2 and on the movable plate 21, with the bearing plate 41 and lifting plate 42 corresponding to the notches on the L-shaped plate 2 and the movable plate 21, respectively. The fixed frame 1 has a first conveying unit 5 for driving the second electric telescopic rods 4 away from the fixed frame 1. A spray gun 7 is provided inside the fixed frame 1. After the injection molded part is placed in the fixed frame 1, the bottom surfaces of the inner sides of the two L-shaped plates 2 support both sides of the injection molded part. Then, the first electric telescopic rod 22 is activated to drive the moving plate 21 downward, so that the moving plate 21 presses and fixes the injection molded part. The spray gun 7 is connected to the external glue supply device through the pipe, so that the spray gun 7 can evenly distribute the glue onto the injection molded part. During the glue application process, the first conveying unit 5 can drive the second electric telescopic rod 4 to move towards the fixed frame 1, so that the supporting plate 41 and the lifting plate 42 enter the notches on the L-shaped plate 2 and the moving plate 21 respectively (the moving plate 21 is U-shaped). The telescopic end of the second electric telescopic rod 4 can drive the lifting plate 42 to move up or down to cooperate with the supporting plate 41 to tighten and fix the injection molded part. After the glue application is completed, the first electric telescopic rod 22 drives the moving plate 21 to move upward away from the injection molded part, and the first conveying unit 5 drives the second electric telescopic rod 4 away from the fixed frame 1. After the injection molded part is clamped by the lifting plate 42, it can be moved out of the fixed frame 1. An external conveyor belt can be set directly below the first conveyor unit 5. Several strip-shaped protrusions are evenly distributed on the external conveyor belt. When the two second electric telescopic rods 4 move downward, the processed injection molded part can be placed on the external conveyor belt. The strip-shaped protrusions can support the injection molded part. Then the first conveyor unit 5 continues to drive the two second electric telescopic rods 4 away from the fixed frame 1, so that the support plate 41 can be pulled out from the bottom of the injection molded part (the distance from the bottom to the top of the strip-shaped protrusion is greater than the distance from the top to the bottom of the support plate 41), thus completing the automatic unloading of the injection molded part. The first conveyor unit 5 includes a frame, a conveyor belt, a drive roller, a driven roller, and a drive motor. The drive roller and the driven roller are rotatably connected in the frame. The drive motor is fixed in the frame and its shaft is fixed to the drive roller. After driving the drive motor, the drive roller can be driven to rotate, so that the conveyor belt drives the driven roller to start rotating.

[0015] like Figure 1 , Figure 2 and Figure 3As shown, an automatic telescopic rod 3 is provided on both sides of the fixed frame 1. A motor 31 is fixed to the telescopic end of the automatic telescopic rod 3. The rotating shaft of the motor 31 is fixed to the outer wall of the L-shaped plate 2. A hydraulic rod 51 is fixed on the conveying surface of the conveying unit 5. A connecting frame 52 is fixed to the telescopic end of the hydraulic rod 51. Two symmetrical moving blocks 53 are slidably connected inside the connecting frame 52. A second electric telescopic rod 4 is fixed to the top of the moving blocks 53. A bidirectional screw 54 is rotatably connected inside the connecting frame 52 and threaded to the two moving blocks 53. A second motor 55 is fixed inside the connecting frame 52 and its rotating shaft is connected to the end of the bidirectional screw 54. The fixed ends of the two No. 1 automatic telescopic rods 3 pass through the fixed frame 1 respectively. The telescopic ends of the No. 1 automatic telescopic rods 3 are connected to the main body of the No. 1 motor 31 through a fixed block. After the No. 1 automatic telescopic rods 3 are started, the two L-shaped plates 2 can be driven to move closer or further apart to fix injection molded parts of different sizes. After the distance between the two L-shaped plates 2 is adjusted, the No. 2 motor 55 can be started to rotate the bidirectional lead screw 54, causing the two moving blocks 53 to move closer or further apart. After adjusting the position of the No. 2 electric telescopic rod 4, the bearing plate 41 and the lifting plate 42 continue to correspond to the notches on the L-shaped plate 2 and the moving plate 21 respectively, without affecting the subsequent unloading operation of the injection molded parts. Furthermore, when both the top and bottom surfaces of the injection molded parts need to be coated with glue, the top surface of the injection molded part is coated with glue first, and then the two No. 1 motors 31 are started to rotate the two L-shaped plates 2 simultaneously. This allows the top and bottom surfaces of the injection molded part to be swapped. Then, the support plate 41 and lifting plate 42 can be inserted into the notches on the L-shaped plate 2 and moving plate 21, respectively. When the moving plate 21 moves upward and no longer fixes the injection molded part, and the part needs to be unloaded, the hydraulic rod 51 drives the connecting frame 52 to move upward. The connecting frame 52 can then drive the second electric telescopic rod 4 to move upward via the moving block 53, causing the support plate 41 and lifting plate 42 to move upward synchronously, lifting the injection molded part upward and separating it from the L-shaped plate 2. This prevents friction between the injection molded part and the L-shaped plate 2 when it is removed from the fixed frame 1, facilitating subsequent removal of the injection molded part from the fixed frame 1. Furthermore, after the injection molded part is removed from the fixed frame 1, the hydraulic rod 51 can also drive the connecting frame 52 to move downward, allowing the injection molded part to be placed on the external conveyor belt.

[0016] like Figure 1 and Figure 2 As shown, a battery 23 is fixed on the L-shaped plate 2, and rubber pads 24 are fixed on the top of the L-shaped plate 2 and the bottom of the movable plate 21. The battery 23 can supply power to the first electric telescopic rod 22, and the main body of the first electric telescopic rod 22 is fixed to the inner side of the L-shaped plate 2 by a reinforcing block; the rubber pads 24 can increase the friction between the L-shaped plate 2 and the movable plate 21 and the injection molded part, so as to better fix the injection molded part; the same rubber pads 24 can also be set on the bearing plate 41 and the lifting plate 42.

[0017] like Figure 1 As shown, a second conveying unit 8 is fixed on both sides of the fixed frame 1. A second automatic telescopic rod 81 is fixed on the conveying surface of the second conveying unit 8. A connecting plate 82 is fixed on the telescopic end of the second automatic telescopic rod 81. A third motor 73 is fixed on one of the connecting plates 82. A one-way screw 72 is fixed on the shaft of the third motor 73. A connecting block 71 that is fixed to the spray gun 7 is threaded onto the one-way screw 72. The second conveyor unit 8 has the same configuration as the first conveyor unit 5, and will not be described in detail here. A limiting rod (not shown in the figure) is fixed between the two connecting plates 82, passing through the connecting block 71. The limiting rod is slidably connected to the connecting block 71. Activating the third motor 73 (the first motor 31, the second motor 55, and the third motor 73 can all be servo motors) rotates the one-way lead screw 72, which in turn causes the connecting block 71 to move the spray gun 7, changing its position for spraying the areas of the injection molded part that require adhesive. Simultaneously, the second conveyor unit 8 can be activated to move the spray gun 7 forward or backward (towards...). Figure 1 (As shown in the diagram), the spray gun 7 can also be moved downwards by activating the second automatic telescopic rod 81, adjusting the distance between the spray gun 7 and the injection molded part; by moving the spray gun 7 forward, backward, left, right, up, and down, the injection molded part can be sprayed with adhesive from all directions.

[0018] like Figure 1 and Figure 3 As shown, a fixing plate 6 is fixed to one side of the fixing frame 1, and a reinforcing rod connected to the fixing frame 1 is fixed on the fixing plate 6; the bottom of the fixing plate 6 is fixed to the top of the first conveying unit 5. There are two first conveying units 5. The fixing plate 6, together with the reinforcing rod, can increase the firmness of the first conveying unit 5 fixed to the fixing frame 1.

[0019] like Figure 1 As shown, the bottom of the fixing frame 1 is connected to a collection frame 9. The collection frame 9 can collect the adhesive dripping down from the injection molded part, and a heating device can be installed inside the collection frame 9 to prevent the adhesive inside the collection frame 9 from solidifying.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
