Description

Technical Field

[0001] The utility model relates to the technical field of camera module processing equipment, in particular to an automatic rolling device for a transfer machine. Background Art

[0002] During the processing of the camera module, FOL reported that the centrifugal cleaning machine had a high material throw rate (the probability of material falling off during cleaning) when cleaning the products after SMT mounting, generally in the range of 8%-15%.

[0003] In order to reduce the material rejection rate, after SMT patching, the products after SMT patching were manually pressed to remove the bubbles in the high-temperature glue used in the products. However, the manual pressing force was uneven and the bubbles were not completely eliminated, which still caused the FOL centrifugal cleaning machine to have a material rejection rate of about 1%. In addition, 2 people were required to perform manual pressing per shift, and a total of 4 people were required to perform pressing during the day and night shifts, resulting in high labor costs.

[0004] Transfer machines are often used to transfer and transport products between different processing steps. Specifically, the products are placed on a carrier, and the carrier is placed on the track of the transfer machine. A material receiving clip is provided at the discharge port, and the product is pushed into the material receiving clip through the jacking platform and push rod on the track. The entire work is only for product transfer and transportation, which results in a certain amount of time and space waste.

[0005] Therefore, there is an urgent need for an automatic rolling device for a transfer machine, which can evenly press the product during transfer and transportation, discharge bubbles in the high-temperature glue of the product, and reduce the throwing rate and labor costs. Utility Model Content

[0006] The utility model aims to provide an automatic rolling device for a transfer machine, which can uniformly press products during transfer and transportation, discharge bubbles in the high-temperature glue of the products, and reduce the throwing rate and labor costs.

[0007] The utility model provides the following basic scheme: an automatic rolling device for a transfer machine, arranged at the discharge port of the track of the transfer machine, comprising: a mechanical bearing upper and lower double roller spring device, a roller fixing bracket and a push rod;

[0008] The mechanical bearing upper and lower double roller spring device comprises: an upper roller and a lower roller;

[0009] The lower roller is arranged at the discharge port of the track of the transfer machine;

[0010] The upper roller is arranged above the lower roller through roller fixing brackets arranged on both sides of the track;

[0011] A spring device is provided on the roller fixing bracket, and the upper roller is pressed down to return to its original position in the direction of the lower roller under the elastic force of the spring device;

[0012] The push rod is arranged on the lifting platform of the transfer machine, and the push rod is an L-shaped Y-mouth push rod, which is used to push the product through the upper and lower double roller spring devices of the mechanical bearing.

[0013] Beneficial effects of the basic solution: We analyzed the material dropping situation of the FOL feedback centrifugal cleaning machine and found that the reason for the high material throwing rate was that the product and the high temperature glue were not bonded together and there were bubbles in the high temperature glue. When the FOL feedback centrifugal cleaning machine rotated at high speed, water entered the high temperature glue bubbles and the high-speed rotating product separated from the high temperature glue. It is only necessary to squeeze out the high temperature glue bubbles, and the product can be completely attached to the high temperature glue without dropping the material. However, the strength of each person pressing is inconsistent, and some places will not be pressed well, which will still cause material throwing;

[0014] Therefore, this scheme arranges an automatic rolling device of the transfer machine at the discharge port of the track of the transfer machine, which specifically includes an upper and lower double roller spring device of a mechanical bearing, a roller fixing bracket and a push rod; the upper and lower double roller spring device of the mechanical bearing includes: an upper roller and a lower roller; the lower roller is arranged at the discharge port of the track of the transfer machine; the upper roller is arranged above the lower roller through roller fixing brackets arranged on both sides of the track; the push rod is arranged on the lifting platform of the transfer machine, and the push rod is an L-shaped Y-mouth push rod, the short rod of the L-shaped Y-mouth push rod is fixedly connected to the lifting platform, and the long rod of the L-shaped Y-mouth push rod is parallel to the inner wall of the track, and is used to push the product through the upper and lower double roller spring device of the mechanical bearing, the upper roller and the lower roller press the product evenly to squeeze out the bubbles in the high-temperature glue, and the upper roller is connected with a spring device, and the upper roller presses the lower roller under the elastic force of the spring device to ensure the pressing effect, and at the same time avoid the upper roller from crushing the product and causing batch defects.

[0015] In addition, compared with the flat push rod of the traditional transfer machine, this solution adopts an L-shaped Y-mouth push rod. The short rod of the L-shaped Y-mouth push rod is fixedly connected to the jacking platform. The L-shaped Y-mouth push rod can prevent the product from jumping when the product is pressed by the upper roller and the lower roller, thereby ensuring the pressing effect.

[0016] In summary, this solution can perform uniform pressing during product transfer and transportation, discharge bubbles in the high-temperature glue of the product, and reduce the throwing rate and labor costs.

[0017] Furthermore, the roller fixing bracket comprises: a base, a lower support rod and an upper support rod;

[0018] The base is arranged on both sides of the track at the discharge port, and a lower mounting hole is arranged at the lower part of the base, which is aligned with the mounting holes arranged on the inner walls of both sides of the track at the discharge port. The lower support rod passes through the lower roller, and both ends pass through the mounting holes and the lower mounting holes, so that the lower roller is installed at the discharge port of the track;

[0019] An upper mounting hole is arranged on the upper part of the base, which is higher than the track. The upper support rod passes through the upper roller, and both ends pass through the upper mounting hole, so that the upper roller is installed above the lower roller.

[0020] Beneficial effect: The roller fixing bracket is used to install the upper roller and the lower roller, which is convenient for replacement and cleaning.

[0021] Furthermore, the upper roller and the lower roller are made of polyurethane rubber wheels.

[0022] Beneficial effects: The soft polyurethane in the polyurethane rubber wheel is mainly a thermoplastic linear structure. It has better stability, chemical resistance, resilience and mechanical properties than PVC foam material, smaller compression deformation, good heat insulation, sound insulation, shock resistance and anti-toxic properties, and is suitable for roller material to ensure the pressing effect, while avoiding the upper roller from crushing the product and causing batch defects.

[0023] Further, a rectangular hole is provided on the upper portion of the base;

[0024] Grooves are provided on the inner walls on both sides of the rectangular hole in the vertical direction;

[0025] A slider is arranged in the rectangular hole, an upper mounting hole is arranged on the slider, and two ends of the slider are inserted into the grooves;

[0026] The spring device comprises: a support plate, a spring support rod, a limit bolt and a spring;

[0027] The support plate is located above the slider, with both ends snapped into the grooves;

[0028] A support mounting hole is provided on the top surface of the slider, one end of the spring support rod is installed in the support mounting hole, and the other end passes through a through hole provided on the support plate and is connected to the top surface of the base;

[0031] Beneficial effect: The spring is pressed by the slider and the support plate. Under the interaction force, the upper roller is pressed too long and pushed upward by the product. The spring also gives the upper slider a downward force, so that the upper roller moves downward to ensure the pressing effect.

[0032] Further, the L-shaped Y-mouth push rod comprises: a short plate and a long rod;

[0033] One end of the long rod is connected to one side of the short board, the long rod is perpendicular to the top surface of the short board, and the other end is provided with a V-shaped opening;

[0034] The short plate is connected to the jacking platform, the long rod is parallel to the inner wall of the track and is located on one side of the upper roller and the lower roller.

[0035] Beneficial effects: The L-shaped Y-mouth push rod and the V-shaped opening can fork the carrier plate to prevent the carrier plate and the product from jumping when the product placed on the carrier plate is pressed by the upper and lower rollers, thereby ensuring the pressing effect.

[0036] Furthermore, the spring in the spring device is made of SUS304-WPB, the spring compression length is 10 mm, and the spring coefficient K=33.9 g / mm.

[0037] Beneficial effects: The spring in the spring device is made of SUS304-WPB, the spring compression length is 10mm, and the spring coefficient K=33.9g / mm, which can ensure the pressing effect and improve the durability of this solution. BRIEF DESCRIPTION OF THE DRAWINGS
