[0002] In some industrial automated manufacturing processes, multiple rollers are threaded onto a single drive shaft to form a roller assembly for transporting materials. For example, in the production of large-scale screen devices, roller assemblies are required to transport glass panels. However, in related technologies, this is typically done manually by threading multiple rollers onto a drive shaft, a very inefficient method. Summary of the Invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. 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 being sleeved on the sleeve, a side wall of one end of the sleeve being provided with a first step, and an opposite end being provided with a second step, the wheel body being 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 move the first roller 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 onto 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] Controlling the first manipulator to apply a first driving force to the i-th roller, and gradually increasing the strength of the first driving force from zero until the i-th roller performs a first rotation along a preset direction, and obtaining 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 approaching 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 blanking processing on the rotating shaft.

[0013] The roller assembly manufacturing method according to the embodiment of the present application has at least the following beneficial effects: The roller is first heated using a heating module, which causes the roller sleeve to expand, thereby temporarily increasing the sleeve's cross-sectional area and facilitating subsequent sleeve attachment to the rotating shaft. A first manipulator is then controlled to clamp the first roller from the heating module, sleeve the first roller's sleeve onto the rotating shaft, and move the first roller axially along the rotating shaft. When the temperature of the (i-1)th roller is detected to be below a preset temperature threshold, indicating that the (i-1)th roller has been secured to the rotating shaft, assembly of the next roller can now proceed. Therefore, the first manipulator is controlled to clamp the i-th roller from the heating module, sleeve the i-th roller's sleeve onto the rotating shaft, and move the i-th roller axially along the rotating shaft until the i-th roller abuts the (i-1)th roller. Then, the first manipulator is controlled to apply a first driving force to the i-th roller, and the force value of the first driving force is gradually increased from zero until the i-th roller makes a first rotation along a preset direction, and the first force value of the first driving force when the i-th 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 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 and second driving forces. When it is detected that the first step of the N-th roller is engaged with the second step of the N-1-th roller, and the temperature of the N-th 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 roller assembly is produced automatically, and 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.

Figure 3 , Figure 3 The assembly module 100 includes a first base 110, a turntable 120, and a support 130. The turntable 120 is vertically arranged and movably arranged on one side of the first base 110. The support 130 is installed on the first base 110, and a groove is provided on the top of the support 130. Figure 4 , Figure 4 It is a structural diagram of the jacketing module of the embodiment of the present application. The jacketing module 400 includes a second base 410, a first bearing assembly 420 and a heating assembly 430. The first linear drive assemblies 440 are respectively provided on the opposite sides of the second base 410. The first bearing assembly 420 is respectively connected to the two first linear drive assemblies 440, and the heating assembly 430 is located above the second base 410; the jacketing module 400 also includes a third base (not shown in the figure), a third linear drive assembly 470, a clamping assembly 480 and a second bearing assembly 460. The third base is located on one side of the second base 410. The second linear drive assemblies 450 are respectively provided on the opposite sides of the third base. The second bearing assembly 460 is respectively connected to the two second linear drive assemblies 450; the third linear drive assembly 470 is mounted above the third base, and the clamping assembly 480 is installed on the third linear drive assembly 470. Reference Figure 5 , Figure 5Schematic diagram of the structure of the roller of an embodiment of the present application. The roller 720 includes a sleeve 722 and a wheel body 721. The wheel body 721 is sleeved on the sleeve 722. The side wall of one end of the sleeve 722 is provided with a first step 7221, and the other opposite end is provided with a second step 7222. The wheel body 721 is located between the first step 7221 and the second step 7222. The sleeve 722 is a hollow structure so that the sleeve 722 can be sleeved on the rotating shaft 710. 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. Multiple rollers 720 are placed in the heating module 300, and water is poured into the heating module 300 so that the rollers 720 are immersed in the water. The heating module 300 heats the water to achieve heating of the rollers 720.

[0077] Specifically, the second manipulator 500 moves the rotating shaft 710, which is not covered with a protective film, to the second carrier assembly 460. The second manipulator 500 also moves the protective film to the first carrier assembly 420. The first linear drive assembly 440 then drives the first carrier assembly 420 so that it is located below the heating assembly 430. 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 third linear drive assembly 470 drives the rotating shaft 710 to insert the rotating shaft 710 into the protective cover 800. The second manipulator 500 then moves the rotating shaft 710, covered with the protective cover 800, into the lower mold 610. The mold drive assembly is then controlled to press the upper mold 620 against the lower mold 610, and the injection molding assembly is controlled to perform injection molding to seal the opening of the protective cover 800. The injection molding assembly is equipped with a pipe for injection molding, which guides the injection liquid to the opening of the protective cover 800 through the pipe. After the injection liquid cools and solidifies, the opening of the protective cover 800 is sealed. Then, the first robot 200 is controlled to fix the rotating shaft 710 to the assembly module 100, and the heating module 300 is controlled to heat the roller 720. The first robot 200 is controlled to install multiple heated rollers 720 on the rotating shaft 710 to form a roller assembly.

[0078] In one embodiment, referring to Figure 4 The sleeve module 400 is further provided with a fourth linear drive assembly 490 , which 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 in passing 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 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. Furthermore, 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.

[0081] Based on the above roller assembly production equipment, a manufacturing method of the roller assembly of the first embodiment of the present application is proposed. Figure 6 , Figure 6 This is a flow chart of the steps of the roller assembly manufacturing method according to an embodiment of the present application. The roller assembly manufacturing method according to the first aspect of the present application is applied to the roller assembly production equipment according to the above embodiment. The roller assembly manufacturing method according to 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: Control the first manipulator to clamp the first roller from the heating module, sleeve the sleeve of the first roller onto the rotating shaft, and control 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 rotation axis 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 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 onto 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; where i is a positive integer, 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. This 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 inserted into the rotating shaft 710, and the i-th roller 720 refers to the i-th roller 720 inserted into the rotating shaft 710.

[0089] It should be noted that when the temperature of the roller 720 falls below the preset temperature threshold, it indicates that the roller 720 has cooled down. After cooling, the cross-sectional area of ​​the sleeve 722 of the roller 720 returns to the cross-sectional area before expansion. Therefore, the roller 720 can be securely sleeved on the rotating shaft 710, so that the roller 720 and the rotating shaft 710 are relatively fixed. This application does not specifically limit 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: Control the first manipulator to apply a first driving force to the i-th roller, and gradually increase the strength 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;

[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 will no longer increase.

[0093] Step S660: 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, controlling the first manipulator to apply a second driving force to the i-th roller until the first step of the i-th roller engages with the second step of the i-1-th roller, and then controlling the first manipulator to stop applying the first and second driving forces; wherein the second driving force is used to drive the i-th roller to move in a direction closer 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 required 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 indicates that the first step 7221 of the i-th roller 720 and the second step 7222 of the i-1-th roller 720 are engaged. At this time, when the i-th roller 720 rotates, it will also drive the i-1-th roller 720 and the rotating shaft 710 to rotate. Therefore, a greater 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, no second driving force is required.

[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 can be either 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 the preset temperature threshold, the first manipulator is controlled to perform blanking 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, through steps S610 to S670, first heats the roller 720 using the heating module 300, causing the sleeve 722 of the roller 720 to expand, thereby temporarily increasing the cross-sectional area of ​​the sleeve 722 and facilitating the subsequent sleeve 722 being mounted on the rotating shaft 710. The first manipulator 200 is then controlled to clamp the first roller 720 from the heating module 300, mount the sleeve 722 of the first roller 720 on the rotating shaft 710, and control the first manipulator 200 to move the first roller 720 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 shaft sleeve 722 of the i-th roller 720 is mounted 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. The first manipulator 200 is then controlled to apply a first driving force to the i-th roller 720, gradually increasing the force of the first driving force from zero until the i-th roller 720 performs a first rotation in a preset direction, and obtaining a first force value of the first driving force during the i-th roller 720's first rotation. If it is detected that the first force value is less than a preset force threshold, the first manipulator 200 is controlled to apply a second driving force to the i-th roller 720 during the i-th roller 720's first rotation, until the first step 7221 of the i-th roller 720 engages with the second step 7222 of the (i-1)-th roller 720. The first manipulator 200 is then controlled to stop applying the first and second driving forces. If it is detected that the first step 7221 of the N-th roller 720 engages with the second step 7222 of the (N-1)-th roller 720, and the temperature of the N-th roller 720 is lower than a preset temperature threshold, the first manipulator 200 is controlled to perform a blanking process on the rotating shaft 710. In this way, automated production of the roller assembly is achieved, improving production efficiency. Furthermore, the first step 7221 and the second step 7222 between two adjacent rollers 720 are engaged and connected, allowing the two adjacent rollers 720 to interact with each other, ensuring that when the rotating shaft 710 rotates, each roller 720 rotates synchronously with the rotating shaft 710. Therefore, the roller assembly manufactured in this 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 do not contact each other and are only connected by the rotating shaft 710. As a result, when the rotating shaft 710 rotates, some of the rollers 720 may be out of sync, for example, some of the rollers 720 may slip, resulting in poor quality. 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, reducing the probability of the rollers 720 being out of sync and the probability of the rollers 720 slipping.

[0103] In some embodiments, after controlling the first manipulator 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 increase 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, it is determined that the first step of the i-th roller is engaged 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 having 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. At this time, 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. Through steps S662 to S663, it can be fully 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 turntable 120 so that when the rotating shaft 710 rotates, it can drive the turntable 120 to rotate, thereby preventing the rotating shaft 710 from being locked.

[0111] Step S631: Control the first manipulator to move the first roller along the axial direction of the rotating shaft until the first roller abuts against the support 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 according to 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 mounted on the rotating shaft 710, the friction between the roller 720 and the rotating shaft 710 is relatively low, which can easily cause the roller 720 to slip. However, the present application controls the sleeve assembly module 400 to insert the rotating shaft 710 into the protective sleeve 800 through steps S510 to S520, controls the second manipulator 500 to transport the rotating shaft 710 with the protective sleeve 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 sleeve 800. In this way, the outer surface of the protective sleeve 800 is relatively rough, which can increase the friction and reduce the probability of the roller 720 slipping.

[0117] In some embodiments, the method for manufacturing a roller assembly according to 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 carrying assembly away from the heating assembly;

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

[0120] Step S430: Control the first linear drive assembly to drive the first supporting assembly to move so that the first supporting assembly is located below the heating assembly, and control 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 , thereby causing the heated protective cover 800 to expand and temporarily increase the cross-sectional area of ​​the protective cover 800 , so as to facilitate 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 move 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 supporting 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 move 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 this embodiment of the present application, through steps S521 to S523, the rotating shaft 710, equipped with the protective cover 800, is placed on the lower mold 610. After the upper mold 620 and the lower mold 610 are pressed together, the injection molding assembly 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 groove is formed, and the opening of the protective cover 800 is located in the injection groove. The injection molding assembly injects injection liquid into the injection groove through a pipe, so that the injection liquid can seal the opening of the protective cover 800 after solidification. This prevents the protective cover 800 from separating from the rotating shaft 710 when the rotating shaft 710 moves.

The roller assembly manufacturing device is applied to the roller assembly production equipment of the above embodiment.

The wheel body 721 is located between the first step 7221 and the second step 7222.

[0136] The first motion unit 730 is used to control the first manipulator 200 to clamp the first roller 720 from the heating module 300, sleeve the shaft sleeve 722 of the first roller 720 on the rotating shaft 710, and control the first manipulator 200 to move the first roller 720 along the axial direction of the rotating shaft 710;

[0137] The second motion unit 740 is configured to, upon detecting that the temperature of the (i-1)th roller 720 is lower than a preset temperature threshold, control the first manipulator 200 to clamp the i-th roller 720 from the heating module 300, sleeve the shaft sleeve 722 of the i-th roller 720 onto the rotating shaft 710, and control the first manipulator 200 to move the i-th roller 720 along the axial direction of the rotating shaft 710 until the i-th roller 720 abuts against the (i-1)th roller 720; wherein i is a positive integer, 2≤i≤N, and N is a preset number;

[0138] The first force applying unit 750 is configured to control the first manipulator 200 to apply a first driving force to the i-th roller 720, gradually increasing the force value of the first driving force from zero until the i-th roller 720 performs a first rotation along a preset direction, and obtaining a first force value of the first driving force when the i-th roller 720 performs the first rotation;

[0139] The second force applying unit 760 is configured to, upon detecting that the first force value is less than a preset force threshold, control the first manipulator 200 to apply a second driving force to the i-th roller 720 during the first rotation of the i-th roller 720 until the first step 7221 of the i-th roller 720 engages with the second step 7222 of the i-1-th roller 720, and then control the first manipulator 200 to stop applying the first and second driving forces; wherein the second driving force is used to drive the i-th roller 720 to move in a direction approaching the i-1-th roller 720;

[0140] The unloading unit 770 is used to control the first robot 200 to unload the rotating shaft 710 when it detects 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 the preset temperature threshold.

[0141] The roller assembly manufacturing apparatus of the embodiment of the present application is used to perform the roller assembly manufacturing method of the embodiment of the first aspect of the present application. When performing the method, the roller 720 is first heated by the heating module 300, which can cause the sleeve 722 of the roller 720 to expand, thereby temporarily increasing the cross-sectional area of ​​the sleeve 722, facilitating the subsequent sleeve 722 being mounted on the rotating shaft 710. The first manipulator 200 is then 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 move the first roller 720 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 shaft sleeve 722 of the i-th roller 720 is mounted 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. The first manipulator 200 is then controlled to apply a first driving force to the i-th roller 720, gradually increasing the force of the first driving force from zero until the i-th roller 720 performs a first rotation in a preset direction, and obtaining a first force value of the first driving force during the i-th roller 720's first rotation. If it is detected that the first force value is less than a preset force threshold, the first manipulator 200 is controlled to apply a second driving force to the i-th roller 720 during the i-th roller 720's first rotation, until the first step 7221 of the i-th roller 720 engages with the second step 7222 of the (i-1)-th roller 720. The first manipulator 200 is then controlled to stop applying the first and second driving forces. If it is detected that the first step 7221 of the N-th roller 720 engages with the second step 7222 of the (N-1)-th roller 720, and the temperature of the N-th roller 720 is lower than a preset temperature threshold, the first manipulator 200 is controlled to perform a blanking process on the rotating shaft 710. In this way, automated production of the roller assembly is achieved, improving production efficiency. Furthermore, the first step 7221 and the second step 7222 between two adjacent rollers 720 are engaged and connected, allowing the two adjacent rollers 720 to interact with each other, ensuring that when the rotating shaft 710 rotates, each roller 720 rotates synchronously with the rotating shaft 710. Therefore, the roller assembly manufactured by this application is of high quality.
