Description

Technical Field

[0001] The utility model relates to the technical field of carrier belt support structures, in particular to a structure that eliminates inching motion and continuous motion. Background Art

[0002] The existing carrier tape assembly process is offline, meaning the electroplating carrier tape is assembled and then transported to the electroplating site. This process can easily cause scratches and bumps in the carrier tape, making it difficult to vacuum-pack the products after carrier tape assembly, leading to product oxidation. During the online assembly process, it was discovered that the assembly equipment uses inching motion, while the electroplating line uses continuous motion. This discrepancy needed to be eliminated.

[0003] The prior art discloses a patent with announcement number CN221853656U. The scheme includes a side plate, the outer wall of the side plate is fixedly connected to the conveying mechanism, and the inner part of the side plate is provided with a limiting groove. By starting the motor, the conveying roller fixedly connected to the outer wall of the rotating rod can be rotated, and the carrier belt passes through the conveying roller and the transmission roller. The carrier belt will squeeze the transmission roller, causing the connecting rod to slide along the limiting groove, which plays the effect of pulling and guiding carrier belts of different thicknesses, thereby improving the scope of application. By pulling the pull rod, the anti-slide plate can be driven to move and release the squeezing limit on the sleeve rod, and the sleeve ring can be moved to the edge of the carrier belt, so that the limiting plate limits the two sides of the carrier belt relative to each other, preventing the carrier belt from deviating during the pulling process. By starting the hydraulic rod, the slider can slide along the slide groove to tighten the carrier belt, thereby adjusting the tightness of the carrier belt pulling.

[0004] As the existing devices are used, the shortcomings of this technology are gradually exposed, mainly in the following aspects:

[0005] First, when assembling products on existing carriers, due to the need for different processing steps, the equipment is not arranged in the same longitudinal direction. This makes it difficult to support the carrier at the corner position, affecting the stability of the carrier during feeding.

[0006] Second, when the carrier tape is fed to the assembly machine, the assembly machine feeds the carrier tape at intervals for assembling products. Since the carrier tape unwinding process is continuous, the carrier tape is prone to being unwound too long, which in turn affects the stability of the carrier tape feeding.

[0007] As can be seen from the above, the existing technology obviously has inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0008] In response to the defects in the existing technology, the utility model provides a structure that eliminates inching and continuous motion, so as to solve the problem that the devices in the traditional technology are not arranged in the same longitudinal direction, which makes it difficult to support the carrier at the corner position, affecting the stability of the carrier during feeding.

[0009] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0010] The structure for eliminating inching and continuous motion includes a cache rack, on which a plurality of guide racks are arranged in parallel along the horizontal direction. Each guide rack is also freely slidable along the longitudinal direction of the cache rack, and the guide rack is also rotated with the vertical line as the rotation center.

[0011] As an optimized solution, a material strip support plate is fixedly connected to the side wall of the guide frame close to the lower end portion, and a material strip guide groove is provided on the upper surface of the material strip support plate.

[0012] As an optimized solution, the guide frame is located on the side wall opposite to the material strip support plate and has two material strip rollers installed thereon for rotation in parallel from top to bottom.

[0013] As an optimized solution, a slide rail is fixedly connected to each guide frame on the cache rack along the longitudinal direction, a slide seat is slidably provided on the slide rail, and the slide seat is connected to the material strip support plate through an adjusting bearing.

[0014] As an optimized solution, an adjustment shaft is vertically fixed to the sliding seat, and the inner ring of the adjustment bearing is fixed to the adjustment shaft.

[0015] As an optimized solution, a fixing groove is provided on the lower surface of the strip support plate, and the fixing groove is fixedly connected to the outer ring of the adjustment bearing.

[0016] As an optimized solution, a bearing adapter plate is fixed to the upper surface of the slide seat, and the adjustment shaft is vertically fixed to the bearing adapter plate.

[0017] As an optimized solution, two position sensors are fixedly connected to each slide seat on the cache rack, and the two position sensors are located near the two ends of the slide rail and face the same side.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The carrier tape passing through the corner passes through the tape support plates or tape rollers on several guide racks in sequence. When the subsequent assembly machine feeds the carrier tape intermittently, the carrier tape will deviate at the corner position. The guide rack slides on the slide rail to assist the carrier tape in deflection, ensuring that the carrier tape can still be supported during the deflection process.

[0020] The guide frame slides on the rails to change the relative position of the carrier tape and the buffer rack to achieve the buffering function. Two position sensors detect the front and rear positions of the carrier tape, and the PLC signal monitors the tape position to control the movement of the front and rear machines.

[0021] By adjusting the rotation of the bearing, the offset angle between the material strip support plate and the material strip is made consistent to prevent the material strip from getting stuck.

[0022] The buffer margin can be adjusted by adjusting the forward and backward movement of the slide rail, and the difference between inching and continuous motion can be achieved through margin control;

[0023] This mechanism solves the difference between inch motion and continuous motion and realizes the feasibility of the motion mode for online assembly of products.

[0024] The position of the material strip is monitored by position sensors, and the actions of the front and rear machines are coordinated synchronously to achieve the feasibility of non-stop electroplating. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0030] like Figure 1 and Figure 2 As shown, the structure for eliminating inching and continuous motion includes a cache rack 1, on which a plurality of guide racks 2 are arranged in parallel along the horizontal direction. Each guide rack 2 is also freely slidable along the longitudinal direction of the cache rack, and the guide rack 2 is also rotated with the vertical line as the rotation center.

[0031] A material strip supporting plate 4 is fixedly connected to a side wall of the guide frame 2 near the lower end portion, and a material strip guiding groove 11 is formed on an upper surface of the material strip supporting plate 4 .

[0032] The guide frame 2 is located on the side wall opposite to the material strip supporting plate 4 and is provided with two material strip rollers 12 which rotate in parallel from top to bottom.

[0033] A slide rail 5 is fixedly connected to each guide frame 2 on the cache rack along the longitudinal direction, and a slide seat 6 is slidably provided on the slide rail 5. The slide seat 6 is connected to the material strip support plate 4 through an adjustment bearing 9.

[0034] An adjusting shaft 8 is vertically fixed on the sliding seat 6 , and the inner ring of the adjusting bearing 9 is fixedly connected to the adjusting shaft 8 .

[0035] A fixing groove 10 is formed on the lower surface of the strip support plate 4 , and the fixing groove 10 is fixedly connected to the outer ring of the adjustment bearing 9 .

[0036] A bearing adapter plate 7 is fixed to the upper surface of the slide 6 , and the adjustment shaft 8 is vertically fixed to the bearing adapter plate 7 .

[0037] Two position sensors 3 are fixedly connected to each slide 6 on the cache rack 1 , respectively. The two position sensors 3 are located near both ends of the slide rail 5 and face the same side.

[0038] The working principle of this device is:

[0039] When the height of the carrier tape is low, the tape guide groove 11 on the tape support plate 4 is used to support the bottom of the carrier tape; when the height of the carrier tape is high, two tape rollers 12 are used to support it;

[0040] The carrier tape passing through the corner passes through the tape support plates 4 or tape rollers 12 on the guide frames 2 in sequence. When the subsequent assembly machine feeds the carrier tape intermittently, the carrier tape may deviate at the corner position. The guide frame 2 slides on the slide rail 5 to assist the carrier tape in deflection, ensuring that the carrier tape can still be supported during the deflection process.

[0041] The guide frame 2 slides on the slide rail 5 to change the relative position of the carrier tape and the buffer rack 1 to achieve the buffering function. The two position sensors 3 detect the front and rear positions of the carrier tape. The PLC signal monitors the tape position and controls the movement of the front and rear machines.

[0042] By adjusting the rotation of the bearing 9, the offset angle of the material strip support plate 4 and the material strip is made consistent to prevent the material strip from being stuck;

[0043] The buffer margin is adjusted by adjusting the forward and backward movement of the slide rail 5, and the difference between inching and continuous movement is achieved through margin control;

[0044] This mechanism solves the difference between inch motion and continuous motion and realizes the feasibility of the motion mode for online assembly of products.

[0045] The position of the material strip is monitored by the position sensor 3, and the actions of the front and rear machines are coordinated synchronously to achieve the feasibility of electroplating without stopping.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
