[0013] The advantages of this utility model, which differ from existing technologies, are as follows:

[0014] 1. The present invention relates to a clamping fixture for applying adhesive to automotive rubber strips. When placing the rubber strip, it is positioned in the middle of a placement block. A manual person places the strip from the bottom of the block, and a first cylinder moves a fixing plate downwards. This downward movement of the fixing plate, via a transfer mechanism, moves a push rod downwards and towards the direction of the manual placement, thus clamping the rubber strip. After adhesive application, the fixing plate moves upwards, and the transfer mechanism moves the push rod upwards and away from the direction of the manual placement, ensuring unobstructed access above the middle of the placement block and preventing interference with the manual placement and removal of the rubber strip, thus guaranteeing overall adhesive application efficiency.

[0015] 2. The clamping fixture for applying adhesive to automotive rubber strips according to this utility model uses a first cylinder to drive a fixed plate upward, which in turn drives a push rod to move. The rotating column on the push rod first moves in the square of the vertical groove, allowing the hook-shaped end of the clamping plate to disengage from the placement block. Then, the rotating column enters the inclined groove, allowing the push rod to slide in the first sliding groove, while simultaneously driving the clamping plate to move away from the direction of manual placement. This ensures that there is no obstruction directly above the center of the placement block, guaranteeing efficient removal without affecting the placement of the rubber strip, thus ensuring the overall efficiency of rubber strip placement.

[0033] like Figures 1 to 6As shown, the present invention discloses a clamping fixture for applying adhesive to automotive adhesive strips, comprising a base plate 1; a set of placement blocks 11 are fixedly connected to the base plate 1; the placement blocks 11 have a U-shaped cross-section, and the two ends of the placement blocks 11 are higher and lower respectively; two sets of symmetrically distributed first through slots 15 are provided on the base plate 1; a pair of symmetrically distributed L-shaped plates are fixedly connected to the bottom end of the base plate 1, and a first cylinder 14 is fixedly connected to the end of the L-shaped plates; a fixing plate 16 is provided at the output end of the first cylinder 14; a push rod 17 is provided at the top end of the fixing plate 16 through a rail-shifting mechanism, and the top end of the push rod 17 passes through the first through slot 15 and is provided with a clamping plate 13, which is hook-shaped and located near the high end of the placement blocks 11; an adhesive strip 12 is placed in the middle of the placement blocks 11; in the prior art, when applying adhesive to the adhesive strip 12 using an intelligent device, a fixture is needed to clamp the adhesive strip 12 for convenience. This facilitates subsequent glue application. However, when clamping or releasing the glue strip 12, the clamping plate 13 often operates vertically, which can obstruct the placement and removal of the glue strip 12, affecting the efficiency of manual placement and removal. Therefore, in actual operation, when placing the glue strip 12, it is placed in the middle of the placement block 11, and the operator places it from the lower end of the placement block 11. Then, the first cylinder 14 drives the fixing plate 16 to move down. As the fixing plate 16 moves down, the sliding mechanism drives the push rod 17 to move down and towards the direction of manual placement, thus clamping the glue strip 12. After glue application, the fixing plate 16 moves up, and the sliding mechanism drives the push rod 17 to move up and away from the direction of manual placement, ensuring that there is no obstruction above the middle of the placement block 11, which will not affect the manual placement and removal of the glue strip 12 and ensure the overall glue application efficiency.

[0034] The track-shifting mechanism includes a vertical groove 2; vertical grooves 2 and inclined grooves 21 are provided on both sides of the first through groove 15; the vertical grooves 2 and inclined grooves 21 are interconnected and the connection is smoothly transitioned; a rotating column 22 is rotatably connected to the push rod 17, and the rotating column 22 slides in the vertical grooves 2 and inclined grooves 21; the push rod 17 is slidably connected to the fixed plate 16 through a sliding unit;

[0035] The sliding unit includes a first sliding groove 23; the fixed plate 16 has a first sliding groove 23, and the bottom end of the push rod 17 is slidably connected in the first sliding groove 23; the cross-section of the first sliding groove 23 and the push rod 17 is inverted T-shaped;

[0036] During operation, the first cylinder 14 drives the fixed plate 16 to move upward, and at the same time drives the push rod 17 to move. The rotating column 22 on the push rod 17 first moves in the square of the vertical groove 2, so that the hook end of the clamping plate 13 is separated from the placement block 11. Then the rotating column 22 enters the inclined groove 21, so that the push rod 17 slides in the first sliding groove 23, and at the same time drives the clamping plate 13 to move away from the direction of manual placement, so that there is no obstruction directly above the center of the placement block 11, ensuring the efficiency of retrieval, and at the same time not affecting the placement of the adhesive strip 12, thus ensuring the overall placement efficiency of the adhesive strip 12.

[0037] The push rod 17 has a first threaded groove 24 at its top end; the clamping plate 13 has a first through hole 25; the clamping plate 13 is threadedly connected to the first threaded groove 24 by a threaded rod 26, and the threaded rod 26 passes through the first through hole 25; during operation, the clamping plate 13 can be installed in the first threaded groove 24 through the threaded rod 26 and the first through hole 25, thereby facilitating the installation and replacement of the clamping plate 13;

[0038] The clamping plate 13 has a first cavity 3 inside its hook-shaped end; the bottom of the first cavity 3 has a set of first air outlets 31, and the two sides of the first cavity 3 have second air outlets 32; the bottom of the clamping plate 13 has a first pipe 33, and the first pipe 33 is connected to the first cavity 3 through a first flexible hose 34; the push rod 17 has a first circular groove 35, and when the clamping plate 13 is installed, the first pipe 33 is placed into the first circular groove 35; the bottom plate 1 has an air suction component.

[0039] The suction component includes a second hose 36; a set of second cavities 37 are provided in the base plate 1; a third air outlet 38 is provided at the bottom end of the second cavity 37, and the bottom end of the second cavity 37 is connected to the bottom end of the first circular groove 35 through the second hose 36; a sliding plate 371 is sealed and slidably mounted in the second cavity 37, and a connecting post 381 is fixedly connected to the bottom end of the sliding plate 371, and the bottom end of the connecting post 381 extends out of the base plate 1 and is fixedly mounted on the top end of the fixing plate 16;

[0040] The top of the second cavity 37 is fixedly connected to an air outlet pipe 39, and the top of the air outlet pipe 39 extends out of the bottom plate 1; the third air outlet 38 and the second hose 36 are provided with a one-way valve.

[0041] The openings of the first pipe 33 and the first circular groove 35 are both inverted frustum-shaped;

[0042] During operation, when placing the clamping plate 13, the first pipe 33 is inserted into the opening of the first circular groove 35. Since both the opening of the first pipe 33 and the first circular groove 35 are inverted frustum-shaped, the fitting effect can be guaranteed. Then, when the fixing plate 16 moves upward, the sliding plate 371 will be moved upward through the connecting column. Through the second flexible hose 36, the first circular groove 35, the first flexible hose 34, the first cavity 3, and the first vent 31, the first vent 31 is put into a suction state, so that after the adhesive strip 12 is applied, the adhesive strip 12 is loosened in the placement block 11, making it easy to remove the adhesive strip 12. At the same time, due to the setting of the second vent 32, the suction only loosens the adhesive strip 12, rather than completely adsorbing it. At the same time, when the fixing plate 16 moves downward and clamps the placed adhesive strip 12, the gas in the second cavity 37 is released from the third vent 38. Due to the setting of the one-way valve, the gas is not allowed to be released through the first cavity 3.

[0043] Working principle: When placing the adhesive strip 12, it is placed in the middle of the placement block 11. The operator places it manually from the bottom of the placement block 11. Then, the first cylinder 14 moves the fixing plate 16 downwards. The downward movement of the fixing plate 16, via the rail shifting mechanism, moves the push rod 17 downwards and towards the direction of manual placement, thus clamping the adhesive strip 12. After the adhesive application is complete, the fixing plate 16 moves upwards. The rail shifting mechanism moves the push rod 17 upwards and away from the direction of manual placement, allowing the placement block 11 to... With no obstructions above the middle section, the manual placement and removal of the adhesive strip 12 will not affect the overall adhesive application efficiency. The first cylinder 14 drives the fixed plate 16 to move upward, and at the same time drives the push rod 17 to move. The rotating column 22 on the push rod 17 first moves in the square of the vertical groove 2, allowing the hook-shaped end of the clamping plate 13 to disengage from the placement block 11. Then, the rotating column 22 enters the inclined groove 21, allowing the push rod 17 to slide in the first sliding groove 23, while driving the clamping plate 13 to move away from the direction of manual placement, thereby allowing the middle of the placement block 11 to move upward. With no obstruction directly above, the removal efficiency is ensured, and the placement of the adhesive strip 12 is not affected, thus ensuring the overall placement efficiency of the adhesive strip 12. When placing the clamping plate 13, the first pipe 33 is placed into the opening of the first circular groove 35. Since both the opening of the first pipe 33 and the first circular groove 35 are inverted frustum shapes, the fitting effect can be ensured. Then, when the fixing plate 16 moves upward, it will drive the sliding plate 371 to move upward through the connecting column, through the second flexible hose 36, the first circular groove 35, the first flexible hose 34, the first cavity 3, and the first outlet. The air vent 31 allows the first air vent 31 to be in a suction state, allowing the adhesive strip 12 to loosen within the placement block 11 after the adhesive is applied, making it easier to remove the adhesive strip 12. At the same time, due to the setting of the second air vent 32, the suction only loosens the adhesive strip 12, rather than completely adsorbing it. When the fixing plate 16 moves down and clamps the placed adhesive strip 12, the gas in the second cavity 37 will exit from the third air vent 38. Due to the setting of the one-way valve, the gas will not be allowed to exit through the first cavity 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
