[0002] In some industrial automation manufacturing processes, multiple rollers are required to be threaded on a transmission shaft to form a roller assembly for transporting materials. For example, in the production process of some large-size screen equipment, a roller assembly is required to transport glass panels. In the related art, multiple rollers are usually manually threaded on the transmission shaft to form a roller assembly, which is very inefficient. Summary of the invention

To this end, the present application proposes a roller assembly manufacturing method, device, electronic device and readable storage medium, which can realize automated production of roller assemblies, improve production efficiency, and produce high-quality roller assemblies.

[0004] The roller assembly manufacturing method according to the first aspect of the present application is applied to a roller assembly production device, wherein the roller assembly production device includes a first manipulator, a heating module, and an assembly module;

[0005] The method comprises:

[0006] Controlling the first manipulator to fix the rotating shaft to the assembly module;

[0007] Controlling the heating module to heat the roller; wherein the roller comprises a sleeve and a wheel body, the wheel body is sleeved on the sleeve, a side wall at one end of the sleeve is provided with a first step, and an opposite end is provided with a second step, and the wheel body is located between the first step and the second step;

[0008] Controlling the first manipulator to clamp the first roller from the heating module, sleeve the shaft sleeve of the first roller on the rotating shaft, and controlling the first manipulator to make the first roller move along the axial direction of the rotating shaft;

[0009] When it is detected that the temperature of the i-1th roller is lower than a preset temperature threshold, the first manipulator is controlled to clamp the i-th roller from the heating module, sleeve the shaft sleeve of the i-th roller on the rotating shaft, and control the first manipulator to move the i-th roller along the axial direction of the rotating shaft until the i-th roller abuts against the i-1th roller; wherein i is a positive integer, 2≤i≤N, and N is a preset number;

[0010] Control the first manipulator to apply a first driving force to the i-th roller, and gradually increase the strength value of the first driving force from zero until the i-th roller performs a first rotation along a preset direction, and obtain a first strength value of the first driving force when the i-th roller performs the first rotation;

[0011] When it is detected that the first force value is less than a preset force threshold, during the first rotation of the i-th roller, the first manipulator is controlled to apply a second driving force to the i-th roller until the first step of the i-th roller is engaged with the second step of the i-1-th roller, and the first manipulator is controlled to stop applying the first driving force and the second driving force; wherein the second driving force is used to drive the i-th roller to move in a direction close to the i-1-th roller;

[0012] When it is detected that the first step of the Nth roller is engaged with the second step of the N-1th roller and the temperature of the Nth roller is lower than the preset temperature threshold, the first manipulator is controlled to perform unloading processing on the rotating shaft.

[0013] According to the roller assembly manufacturing method of the embodiment of the present application, at least the following beneficial effects are achieved: firstly, the roller is heated by the heating module, so that the sleeve of the roller can expand, thereby temporarily increasing the cross-sectional area of ​​the sleeve, which is convenient for the sleeve to be sleeved on the rotating shaft later. Then, the first manipulator is controlled to clamp the first roller from the heating module, sleeve the sleeve of the first roller on the rotating shaft, and control the first manipulator to move the first roller along the axial direction of the rotating shaft. Then, when it is detected that the temperature of the i-1 roller is lower than the preset temperature threshold, it means that the i-1 roller has been fixed on the rotating shaft, and the next roller can be assembled at this time, so the first manipulator is controlled to clamp the i roller from the heating module, sleeve the sleeve of the i roller on the rotating shaft, and control the first manipulator to move the i roller along the axial direction of the rotating shaft until the i roller abuts against the i-1 roller. Then, the first manipulator is controlled to apply a first driving force to the ith roller, and the force value of the first driving force is gradually increased from zero until the ith roller makes a first rotation along a preset direction, and the first force value of the first driving force when the ith roller makes the first rotation is obtained; when it is detected that the first force value is less than the preset force threshold, during the first rotation of the ith roller, the first manipulator is controlled to apply a second driving force to the ith roller until the first step of the ith roller is engaged with the second step of the i-1th roller, and the first manipulator is controlled to stop applying the first driving force and the second driving force. When it is detected that the first step of the Nth roller is engaged with the second step of the N-1th roller, and the temperature of the Nth roller is lower than the preset temperature threshold, the first manipulator is controlled to perform blanking processing on the rotating shaft. In this way, the automated production of roller components is realized, and the production efficiency is improved. In addition, the first step and the second step between two adjacent rollers are engaged and connected, so that the two adjacent rollers influence each other, which can ensure that when the rotating shaft rotates, each roller rotates synchronously with the rotating shaft.

The injection molding sealing module 600 includes a mold drive assembly, a lower mold 610 and a lower mold 610, the mold drive assembly is connected to the upper mold 620, and the upper mold 620 is provided with an injection molding assembly.

[0077] Specifically, the rotating shaft 710 without the protective film is transported to the second bearing assembly 460 by the second manipulator 500, and the protective film is transported to the first bearing assembly 420 by the second manipulator 500, and then the first bearing assembly 420 is driven by the first linear drive assembly 440, so that the first bearing assembly 420 is located below the heating assembly 430, and after the protective cover 800 is heated by the heating assembly 430, the clamping assembly 480 is controlled to clamp the rotating shaft 710, and the rotating shaft 710 is driven by the third linear drive assembly 470 to insert the rotating shaft 710 into the protective cover 800. Then, the rotating shaft 710 with the protective cover 800 is transported to the lower mold 610 by the second manipulator 500, and then the mold drive assembly is controlled to drive the upper mold 620 to press fit on the lower mold 610, and the injection molding assembly is controlled to perform injection molding and sealing on the opening of the protective cover 800.

[0078] In one embodiment, referring to Figure 4 The sleeve module 400 is further provided with a fourth linear drive assembly 490 , and the fourth linear drive assembly 490 is used to drive the protective sleeve 800 to move in a direction close to the rotating shaft 710 to assist the rotating shaft 710 to pass through the protective sleeve 800 .

[0079] It should be noted that the first step 7221 matches the second step 7222 , so that the first step 7221 of one roller 720 is engaged and connected with the second step 7222 of another roller 720 .

[0080] It should be noted that the driving direction of the second linear drive assembly 450 is parallel to the driving direction of the first linear drive assembly 440, and the driving direction of the third linear drive assembly 470 is perpendicular to the driving direction of the second linear drive assembly 450. In addition, the driving directions of the first linear drive assembly 440, the second linear drive assembly 450, and the third linear drive assembly 470 are all horizontal directions.

[0081] Based on the above roller assembly production equipment, a method for manufacturing a roller assembly according to the first embodiment of the present application is proposed. Figure 6 , Figure 6 The present invention is a schematic diagram of the steps of the roller assembly manufacturing method of the embodiment of the present application. The roller assembly manufacturing method of the first aspect of the present application is applied to the roller assembly production equipment of the above embodiment. The roller assembly manufacturing method of the first aspect of the present application includes but is not limited to the following steps:

[0082] Step S610, controlling the first manipulator to fix the rotating shaft to the assembly module;

[0083] Step S620, controlling the heating module to heat the roller;

[0084] It is worth noting that, based on the principle of thermal expansion and contraction, after the roller 720 is heated, the sleeve 722 of the roller 720 expands, so that the cross-sectional area of ​​the sleeve 722 increases, thereby facilitating the sleeve 722 to be sleeved on the rotating shaft 710 .

[0085] Step S630, controlling the first manipulator to clamp the first roller from the heating module, sleeve the shaft sleeve of the first roller on the rotating shaft, and controlling the first manipulator to move the first roller 720 along the axial direction of the rotating shaft;

[0086] Specifically, in step S630 , the first manipulator 200 controls the first roller 720 to move along the end close to the rotating shaft 710 fixed by the assembly module 100 .

[0087] Step S640, when it is detected that the temperature of the i-1th roller is lower than the preset temperature threshold, control the first manipulator to clamp the i-th roller from the heating module, sleeve the shaft sleeve of the i-th roller on the rotating shaft, and control the first manipulator to move the i-th roller along the axial direction of the rotating shaft until the i-th roller abuts against the i-1th roller; wherein i is a positive integer, and 2≤i≤N, and N is a preset number;

[0088] It is worth noting that in the roller assembly, the number of rollers 720 on the rotating shaft 710 is a preset number N, and the present application does not specifically limit the preset number, and those skilled in the art can set the preset number according to actual needs. The first roller 720 refers to the first roller 720 that passes through the rotating shaft 710, and the i-th roller 720 refers to the i-th roller 720 that passes through the rotating shaft 710.

[0089] It should be noted that when the temperature of the roller 720 is lower than the preset temperature threshold, it means that the roller 720 has cooled down, and the cross-sectional area of ​​the sleeve 722 of the roller 720 after cooling returns to the cross-sectional area before expansion, so the roller 720 can be firmly sleeved on the rotating shaft 710, so that the roller 720 and the rotating shaft 710 are relatively fixed. The present application does not make a specific limitation on the preset temperature threshold, and those skilled in the art can set the preset temperature threshold according to actual needs.

[0090] In one embodiment, the roller assembly production equipment is provided with a temperature sensor, and the temperature of the roller 720 is detected by the temperature sensor.

[0091] Step S650, controlling the first manipulator to apply a first driving force to the i-th roller, and gradually increasing the force value of the first driving force from zero until the i-th roller performs a first rotation along a preset direction, and obtaining a first force value of the first driving force when the i-th roller performs the first rotation;

[0092] It is worth noting that in step S650, the first robot 200 applies a first driving force to the i-th roller 720, so that the first driving force gradually increases until the i-th roller 720 rotates, and the rotation process is recorded as the first rotation. After the i-th roller 720 rotates, the force value of the first driving force is no longer increased.

[0093] Step S660, when it is detected that the first force value is less than the preset force threshold, during the first rotation of the i-th roller, the first manipulator is controlled to apply the second driving force to the i-th roller until the first step of the i-th roller is engaged with the second step of the i-1-th roller, and the first manipulator is controlled to stop applying the first driving force and the second driving force; wherein the second driving force is used to drive the i-th roller to move in a direction close to the i-1-th roller;

[0094] It is worth noting that when the first force value is less than the preset force threshold, it means that the first step 7221 of the i-th roller 720 and the second step 7222 of the i-1-th roller 720 are not engaged. At this time, only a smaller force is needed to rotate the i-th roller 720. Therefore, it is necessary to control the first manipulator 200 to apply a second driving force to the i-th roller 720 to promote the i-th roller 720 to approach the i-1-th roller 720, and the i-th roller 720 continues to rotate, so that the first step 7221 of the i-th roller 720 can be engaged and connected with the second step 7222 of the i-1-th roller 720.

[0095] When the first force value is greater than or equal to the preset force threshold, it means that the first step 7221 of the i-th roller 720 and the second step 7222 of the i-1-th roller 720 are already engaged and connected, and when the i-th roller 720 rotates, it will drive the i-1-th roller 720 and the rotating shaft 710 to rotate, so a larger force is required to drive the i-th roller 720 to rotate. Therefore, when the first force value is greater than or equal to the preset force threshold, there is no need to apply the second driving force.

[0096] It should be noted that the present application does not limit the preset force threshold, and those skilled in the art can set the preset force threshold according to actual needs.

[0097] It should be noted that the preset direction may be clockwise or counterclockwise. The direction of the first driving force is the same as the preset direction. The direction of the second driving force is parallel to the axial direction of the rotating shaft 710 and points from the i-th roller 720 to the i-1-th roller 720.

[0098] Step S670, when it is detected that the first step of the Nth roller is engaged with the second step of the N-1th roller and the temperature of the Nth roller is lower than a preset temperature threshold, control the first manipulator to perform material unloading processing on the rotating shaft.

[0099] In one embodiment, the roller assembly production equipment further includes a storage device, and the unloading process is: controlling the first robot 200 to move the rotating shaft 710 to the storage device.

[0100] It is worth noting that the embodiment of the present application needs to repeat step S640 to step S660 until the first step 7221 of the Nth roller 720 is engaged with the second step 7222 of the N-1th roller 720, and the temperature of the Nth roller 720 is lower than the preset temperature threshold, indicating that the last roller 720 has been inserted into the rotating shaft 710, and the last roller 720 has been fixed in the rotating shaft 710 after cooling.

[0101] The roller assembly manufacturing method of the embodiment of the present application is through the above steps S610 to S670, firstly, the roller 720 is heated by the heating module 300, so that the sleeve 722 of the roller 720 can expand, thereby temporarily increasing the cross-sectional area of ​​the sleeve 722, and facilitating the subsequent sleeve 722 to be sleeved on the rotating shaft 710. Then, the first manipulator 200 is controlled to clamp the first roller 720 from the heating module 300, sleeve the sleeve 722 of the first roller 720 on the rotating shaft 710, and control the first manipulator 200 to make the first roller 720 move along the axial direction of the rotating shaft 710. Then, when it is detected that the temperature of the i-1th roller 720 is lower than the preset temperature threshold, it means that the i-1th roller 720 has been fixed on the rotating shaft 710, and the next roller 720 can be assembled at this time. Therefore, the first manipulator 200 is controlled to clamp the i-th roller 720 from the heating module 300, and the sleeve 722 of the i-th roller 720 is sleeved on the rotating shaft 710, and the first manipulator 200 is controlled to make the i-th roller 720 move along the axial direction of the rotating shaft 710 until the i-th roller 720 abuts against the i-1th roller 720. Then, the first manipulator 200 is controlled to apply a first driving force to the i-th roller 720, and the force value of the first driving force is gradually increased from zero until the i-th roller 720 performs a first rotation along a preset direction, and a first force value of the first driving force when the i-th roller 720 performs the first rotation is obtained; when it is detected that the first force value is less than the preset force threshold, during the first rotation of the i-th roller 720, the first manipulator 200 is controlled to apply a second driving force to the i-th roller 720 until the first step 7221 of the i-th roller 720 is engaged with the second step 7222 of the i-1-th roller 720, and the first manipulator 200 is controlled to stop applying the first driving force and the second driving force. When it is detected that the first step 7221 of the N-th roller 720 is engaged with the second step 7222 of the N-1-th roller 720, and the temperature of the N-th roller 720 is lower than the preset temperature threshold, the first manipulator 200 is controlled to perform a material unloading process on the rotating shaft 710. In this way, the roller assembly is automatically produced, and the production efficiency is improved. Moreover, the first step 7221 and the second step 7222 between two adjacent rollers 720 are engaged and connected, so that the two adjacent rollers 720 affect each other, and it can be ensured that when the rotating shaft 710 rotates, each roller 720 rotates synchronously with the rotating shaft 710, so the roller assembly manufactured by the embodiment of the present application is of high quality.

[0102] It is worth noting that in the roller assembly of the related art, the rollers 720 and the rollers 720 do not contact each other, and are only connected by the rotating shaft 710, which causes some rollers 720 to be out of sync when the rotating shaft 710 rotates, for example, some rollers 720 slip, and the quality is poor. In the present application, the first step 7221 and the second step 7222 between two adjacent rollers 720 are engaged and connected, so that the two adjacent rollers 720 affect each other. When the rotating shaft 710 rotates, the rotating shaft 710 drives the rollers 720 to rotate, and the rollers 720 drive each other, which can ensure that the rollers 720 rotate synchronously with the rotating shaft 710, reduce the probability of the rollers 720 being out of sync, and reduce the probability of the rollers 720 slipping.

[0103] In some embodiments, after controlling the first robot 200 to apply the second driving force to the i-th roller 720 in step S660, the following steps are further included:

[0104] Step S661, when it is detected that the i-th roller is in a stationary state, continuously increasing the strength value of the first driving force until the i-th roller performs a second rotation along a preset direction;

[0105] Step S662, obtaining a second force value of the first driving force when the i-th roller performs a second rotation;

[0106] Step S663, when it is detected that the second force value is greater than the preset force threshold, determining that the first step of the i-th roller is engaged and connected with the second step of the i-1-th roller.

[0107] Specifically, after step S660, when the first step 7221 of the i-th roller 720 is engaged with the second step 7222 of the i-1-th roller 720, the first driving force with the first force value cannot drive the i-th roller 720 to rotate, and the second driving force cannot drive the i-th roller 720 to move, and the i-th roller 720 is in a stationary state. Therefore, through step S661, when it is detected that the i-th roller 720 is in a stationary state, it can be preliminarily determined that the first step 7221 of the i-th roller 720 is engaged with the second step 7222 of the i-1-th roller 720, and through steps S662 to S663, it can be completely determined that the first step 7221 of the i-th roller 720 is engaged with the second step 7222 of the i-1-th roller 720.

[0108] In some embodiments, step S610 includes step S611, and step S630 includes step S631.

[0109] Step S611, controlling the first manipulator to fix one end of the rotating shaft to the turntable, and allowing the rotating shaft to pass through the groove;

[0110] Specifically, the rotating shaft 710 is fixed in the rotating disk 120 so that when the rotating shaft 710 rotates, it can drive the rotating disk 120 to rotate, thereby preventing the rotating shaft 710 from being locked.

[0111] Step S631, controlling the first manipulator to move the first roller along the axial direction of the rotating shaft until the first roller abuts against the supporting member.

[0112] Specifically, the first roller 720 is limited by the support member 130, thereby limiting the distance between the first roller 720 and the end of the rotating shaft 710. For example, the support member 130 can be set at different positions to adjust the distance between the first roller 720 and the end of the rotating shaft 710.

[0113] In some embodiments, the method for manufacturing a roller assembly in the embodiment of the present application further includes the following steps before step S610:

[0114] Step S510, controlling the sleeve assembly module to insert the rotating shaft into the protective sleeve;

[0115] Step S520, controlling the second robot to carry the rotating shaft covered with the protective cover to the injection molding and sealing module, and controlling the injection molding and sealing module to perform injection molding and sealing on the opening of the protective cover.

[0116] It is worth noting that the surface of the rotating shaft 710 is relatively smooth. When the roller 720 is directly sleeved on the rotating shaft 710, the friction between the roller 720 and the rotating shaft 710 is relatively small, and the roller 720 is prone to slipping. However, the present application controls the sleeve module 400 to insert the rotating shaft 710 into the protective cover 800 through steps S510 to S520, controls the second manipulator 500 to move the rotating shaft 710 sleeved with the protective cover 800 to the injection molding and sealing module 600, and controls the injection molding and sealing module 600 to perform injection molding and sealing on the opening of the protective cover 800. In this way, the outer surface of the protective cover 800 is relatively rough, and the protective cover 800 can increase the friction and reduce the probability of the roller 720 slipping.

[0117] In some embodiments, the method for manufacturing a roller assembly in the embodiment of the present application further includes the following steps before step S510:

[0118] Step S410, controlling the first linear drive assembly to drive the first bearing assembly away from the heating assembly;

[0119] Step S420, controlling the second manipulator to sequentially place a plurality of protective covers on the first carrying assembly;

[0120] Step S430, controlling the first linear drive assembly to drive the first bearing assembly to move, so that the first bearing assembly is located below the heating assembly, and controlling the heating assembly to heat the plurality of protective covers.

[0121] The embodiment of the present application heats the protective cover 800 through steps S410 to S430 , so that the heated protective cover 800 can expand and temporarily increase the cross-sectional area of ​​the protective cover 800 , so as to facilitate the insertion of the rotating shaft 710 into the protective cover 800 .

[0122] In some embodiments, step S510 includes the following steps:

[0123] Step S511, controlling the second manipulator to carry the plurality of rotating shafts not covered with protective covers to the second carrying assembly;

[0124] Step S512, controlling the second linear drive assembly to drive the second bearing assembly to move, so that the second bearing assembly is located below the third drive assembly;

[0125] Step S513, controlling the clamping assembly to clamp the rotating shaft from the second bearing assembly;

[0126] Step S514, controlling the third linear drive assembly to drive the clamping assembly to drive the rotating shaft to move in a direction close to the second base, so that the rotating shaft passes through the protective cover provided on the first bearing assembly.

[0127] In the embodiment of the present application, through steps S511 to S514 , the rotating shaft 710 is passed through the protective cover 800 , thereby increasing the friction between the rotating shaft 710 and the roller 720 .

[0128] In one embodiment, step S520 may include the following steps:

[0129] Step S521, controlling the second robot to carry the rotating shaft covered with the protective cover to the lower mold;

[0130] Step S522, controlling the mold driving assembly to drive the upper mold to press the lower mold;

[0131] Step S523, controlling the injection molding component to perform injection molding and sealing on the opening of the protective cover.

[0132] In the embodiment of the present application, through steps S521 to S523, the rotating shaft 710 provided with the protective cover 800 is placed on the lower mold 610, and then after the upper mold 620 and the lower mold 610 are pressed together, the injection molding component is controlled to perform the injection molding operation. In one embodiment, when the lower mold 610 and the upper mold 620 are pressed together, an injection molding groove is formed, and the opening of the protective cover 800 is located in the injection molding groove. The injection molding component injects injection molding liquid into the injection molding groove through a pipeline, so that the injection molding liquid can seal the opening of the protective cover 800 after solidification. It can avoid the separation between the protective cover 800 and the rotating shaft 710 when the rotating shaft 710 moves.

[0140] The unloading unit 770 is used to control the first robot 200 to unload the rotating shaft 710 when it is detected that the first step 7221 of the Nth roller 720 is engaged with the second step 7222 of the N-1th roller 720 and the temperature of the Nth roller 720 is lower than a preset temperature threshold.

[0141] The roller assembly manufacturing device of the embodiment of the present application is used to perform the roller assembly manufacturing method of the first embodiment of the present application. When performing the method, the roller 720 is first heated by the heating module 300, so that the sleeve 722 of the roller 720 can expand, thereby temporarily increasing the cross-sectional area of ​​the sleeve 722, so as to facilitate the subsequent sleeve 722 to be sleeved on the rotating shaft 710. Then, the first manipulator 200 is controlled to clamp the first roller 720 from the heating module 300, sleeve the sleeve 722 of the first roller 720 on the rotating shaft 710, and control the first manipulator 200 to make the first roller 720 move along the axial direction of the rotating shaft 710.
