Description

Technical Field

[0001] This application relates to the field of bearing processing equipment technology, and in particular to an automated assembly equipment for bearing needle rollers. Background Technology

[0002] Currently, needle roller bearings are roller bearings with cylindrical rollers. Relative to their diameter, the rollers are both thin and long. These rollers are called needle rollers. Despite having a small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact. When the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest, making them particularly suitable for support structures where the radial installation size is limited.

[0003] Regarding the aforementioned technologies, current methods for loading needle roller bearings mostly involve manual placement of the bearings onto the conveyor belt. This manual loading relies heavily on manpower, and with rising labor costs year by year, production costs for enterprises are also increasing. Furthermore, the efficiency of manual operation has a low ceiling, making it difficult to meet the needs of enterprises to expand production scale and increase capacity. At the same time, prolonged repetitive manual operation can easily lead to occupational diseases such as hand muscle strain and joint inflammation for operators. In addition, needle roller bearings are small in size and have sharp edges, posing a risk of finger cuts and mechanical injuries during frequent handling. Once a safety accident occurs, it will not only cause physical harm to employees but also lead to production line shutdowns and additional economic losses. Utility Model Content

[0004] The purpose of this application is to provide an automated assembly equipment for bearing needle rollers, which has advantages such as automated material unloading and solves the problems mentioned in the background art.

[0005] The automated assembly equipment for bearing needle rollers provided in this application adopts the following technical solution: it includes two support plates, a transport mechanism, a concave plate, and an electric unloading mechanism. The electric unloading mechanism includes two fixed blocks fixedly connected to the side of the concave plate. The top of each of the two fixed blocks is fixedly connected to a support column. The top of the two support columns is fixedly connected to a housing. An inclined plate is fixedly connected inside the housing. A cover plate is snapped onto the top of the housing. A handle is fixedly connected to the top of the cover plate. Four mounting blocks are fixedly connected to the inner side of the housing. A sealing plate overlaps the sides of the four mounting blocks. Four sets of threaded holes are opened inside the four mounting blocks and inside the sealing plate. Screws are threaded into the four sets of threaded holes. Two horizontal blocks are fixedly connected to the bottom of the box. An electric push rod is fixedly installed inside each of the two horizontal blocks. A connecting block is fixedly connected to one end of each of the two electric push rods. A horizontal plate is fixedly connected to the top of each of the two connecting blocks. The two horizontal plates are slidably connected inside the box.

[0006] By adopting the above technical solution and setting up an electric feeding mechanism, the electric push rod can drive the horizontal plate to move left and right, which can precisely control the feeding rhythm and quantity of needle roller bearings, avoid the errors and inefficiencies of manual feeding, realize automated continuous feeding, and adapt to the needs of high-speed production lines. The inclined plate design facilitates the sliding of needle roller bearings along the inclined surface, reduces accumulation and jamming, and improves the smoothness of feeding. The sealing plate is fixed by screws and mounting blocks, which can effectively prevent dust and impurities from entering the housing, protect the cleanliness of the needle roller bearings, and avoid bearing installation failures caused by contamination. At the same time, the detachable cover plate and sealing plate design facilitates the filling of the housing or the replacement of needle roller bearings of different specifications, improving the versatility of the equipment.

A drive motor is fixedly installed on the side of the concave plate via a mounting plate. Four support bearings are fixedly connected to the inner side of each concave plate. A rotating shaft is rotatably connected inside each of the two sets of support bearings. One end of one rotating shaft is fixedly connected to the output shaft of the drive motor. Pulleys are fixedly connected to the surfaces of both rotating shafts. A rubber belt is driven between the two pulleys. A conveyor belt is driven between the two rotating shafts.

[0008] By adopting the above technical solution and setting up a transportation mechanism, the drive motor can transmit the needle roller bearings at a uniform speed through the pulley and conveyor belt, ensuring accurate material positioning during installation, reducing transmission errors, and reducing transmission resistance by supporting the cooperation between the bearing and the shaft, thus improving the stability of equipment operation. The conveyor belt is linked with components such as the electric feeding mechanism and the needle loading equipment to form a fully automated production line, reducing manual handling and improving production efficiency.

[0009] Preferably, two L-shaped plates and a robotic arm are fixedly installed on the top of one of the support plates, and bearing orientation detectors are fixedly installed on the sides of the two L-shaped plates.

[0012] By adopting the above technical solution, the needle loading equipment can automatically grab the needle rollers according to the preset program and accurately install them into the inner ring of the bearing, replacing the tedious operation of manual needle loading. This avoids uneven needle roller arrangement or misalignment caused by manual force or angle deviation, ensuring the assembly accuracy of the bearing assembly. The missing needle detector can detect whether there are missing needle rollers during the needle loading process, and promptly alarm or stop the machine to prevent defective products from flowing into the next process and reduce quality risks.

The PLC programmable controller integrates automated control logic and can flexibly adjust parameters (such as feeding speed and transmission rhythm) according to production needs, thereby improving the adaptability of the equipment.

[0015] Preferably, four support legs are fixedly connected to the bottom of the two support plates, and each of the four support legs is provided with a silicone pad at its bottom end.

[0016] By adopting the above technical solution, the support legs and silicone pads can enhance the equipment's vibration resistance, prevent displacement during operation, and reduce noise.

[0017] Preferably, the bottom of one of the support plates is fixedly connected to two boxes, each of the two boxes has a drawer slidably connected inside, and each of the two drawers has a fixing post fixedly connected to its side.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: An automated assembly equipment for bearing needle rollers, referring to... Figure 1 , Figure 4 and Figure 5The device includes two support plates 1, a transport mechanism 2, a concave plate 201, and an electric unloading mechanism 3. The electric unloading mechanism 3 includes two fixing blocks 301 fixedly connected to the side of the concave plate 201. The top of each of the two fixing blocks 301 is fixedly connected to a support column 302. The top of the two support columns 302 is fixedly connected to a box body 303. The inside of the box body 303 is fixedly connected to an inclined plate 304. The top of the box body 303 is snapped with a cover plate 305. The top of the cover plate 305 is fixedly connected to a handle 306. The inner wall of the box body 303 is fixedly connected to four mounting blocks 307. The sides of the four mounting blocks 307 overlap with a sealing plate 308. The inside of the four mounting blocks 307 and the inside of the sealing plate 308 are provided with four sets of threaded holes 310. The inside of each of the four sets of threaded holes 310 is threaded with a screw 309. Two horizontal blocks 311 are fixedly connected to the bottom of the housing 303. An electric push rod 312 is fixedly installed inside each of the two horizontal blocks 311. A connecting block 313 is fixedly connected to one end of each of the two electric push rods 312. A horizontal plate 314 is fixedly connected to the top of each of the two connecting blocks 313. The two horizontal plates 314 are slidably connected inside the housing 303. By setting an electric feeding mechanism 3, the electric push rods 312 can drive the horizontal plates 314 to move left and right, precisely controlling the feeding rhythm and quantity of the needle roller bearings, avoiding errors and inefficiencies associated with manual feeding. To address the challenges of automated continuous feeding and adapt to the needs of high-speed production lines, the inclined plate 304 design facilitates the sliding of needle roller bearings along the inclined surface, reducing accumulation and jamming, and improving the smoothness of material feeding. The sealing plate 308 is fixed to the mounting block 307 by screws 309, which can effectively prevent dust and impurities from entering the inside of the housing 303, protecting the cleanliness of the needle roller bearings and avoiding bearing installation failures caused by contamination. At the same time, the design of the detachable cover plate 305 and sealing plate 308 facilitates the filling of the inside of the housing 303 or the replacement of needle roller bearings of different specifications, improving the versatility of the equipment.

[0026] Please see Figure 1 , Figure 2 and Figure 3The transport mechanism 2 includes a concave plate 201 fixedly mounted on the top of two support plates 1. A drive motor 202 is fixedly mounted on the side of the concave plate 201 via a mounting plate. Four support bearings 203 are fixedly connected to the inner side of each concave plate 201. A rotating shaft 204 is rotatably connected inside each of the two sets of support bearings 203. One end of one rotating shaft 204 is fixedly connected to the output shaft of the drive motor 202. Pulleys 205 are fixedly connected to the surfaces of both rotating shafts 204. A rubber belt 206 is driven between the two pulleys 205. A conveyor belt 207 is driven between the two rotating shafts 204. By setting up the transport mechanism 2, the drive motor 202 can be driven by the pulleys 205 and the conveyor belt 207 to transport the needle roller bearings at a uniform speed, ensuring safety. During the assembly process, the material positioning is precise, reducing transmission errors. The cooperation between the support bearing 203 and the rotating shaft 204 reduces transmission resistance and improves the stability of equipment operation. The conveyor belt 207 is linked with components such as the electric unloading mechanism 3 and the needle loading device 6 to form a fully automated production line, reducing manual handling and improving production efficiency. Two L-shaped plates 17 and a robotic arm 5 are fixedly installed on the top of a support plate 1. Bearing direction detectors 4 are fixedly installed on the sides of the two L-shaped plates 17. The bearing direction detectors 4 can identify the bearing installation direction in real time, avoiding installation failures caused by incorrect direction and improving the product qualification rate. The robotic arm 5, in conjunction with the PLC programmable controller 9, can automatically adjust the needle loading position according to the detection data to achieve high-precision installation, which is especially suitable for the production needs of precision bearings.

[0027] Please see Figure 1 and Figure 2 A needle loading device 6 is fixedly installed on the top of a support plate 1, and a needle leakage detector 7 is fixedly installed on the side of the needle loading device 6. The needle loading device 6 can automatically grab the needle rollers and accurately install them into the inner ring of the bearing according to a preset program, replacing the tedious operation of manual needle loading. This avoids uneven needle roller arrangement or misalignment caused by manual force or angle deviation, ensuring the assembly accuracy of the bearing assembly. The needle leakage detector 7 can detect whether there are missing needle rollers during the needle loading process, and promptly alarm or stop the machine to prevent defective products from flowing into the next process and reduce quality risks. Stainless steel plates 8 are set on the top of both support plates 1, and a PLC programmable controller 9 is fixedly installed on the top of one support plate 1. The stainless steel plate 8 covers the top of the support plate 1, is corrosion-resistant, easy to clean, and adaptable to the industrial production environment. The PLC programmable controller 9 integrates automated control logic and can flexibly adjust parameters (such as feeding speed and transmission rhythm) according to production needs, improving the adaptability of the equipment.

[0028] Please see Figure 1 and Figure 2The bottom of each of the two support plates 1 is fixedly connected to four support legs 10. Each of the four support legs 10 has a silicone pad 11 at its bottom. The support legs 10 and silicone pads 11 enhance the equipment's vibration resistance, prevent displacement during operation, and reduce noise. The bottom of one support plate 1 is fixedly connected to two boxes 12. Each of the two boxes 12 has a drawer 13 slidably connected inside. Each of the two drawers 13 has a fixed post 14 fixedly connected to its side. The boxes 12 and drawers 13 are designed to provide storage space for storing tools or spare parts, improving operational convenience. The top of one support plate 1 is fixedly connected to a support frame 15. An LED light strip 16 is fixedly installed on the side of the support frame 15. The LED light strip 16 installed on the support frame 15 improves the lighting in the working area, making it easier for operators to observe the equipment's operating status or make manual interventions.

[0029] The implementation principle of this application embodiment is as follows: First, the operator holds the handle 306 to open the cover plate 305, and then places the needle roller bearings on the inclined plate 304 inside the housing 303 (this way, the operator does not need to be in the feeding area for filling, which facilitates other processes). The bearings naturally slide down to the top of the horizontal plate 314 at the bottom of the housing 303 under gravity. Then, the PLC programmable controller 9 sends instructions to the electric push rod 312 according to the production rhythm. The push rod drives the horizontal plate 314 to perform reciprocating linear motion. The opening and closing degree of the horizontal plate 314 controls the number and frequency of the falling needle roller bearings. The sealing plate 308 and the cover plate 305 also prevent dust from entering. When it is necessary to change the needle roller bearing specifications, the operator opens the cover plate 305 through the handle 306. After that, the drive motor 202 starts, and the pulley 205 and rubber belt 206 drive the rotating shaft 204 to rotate, thereby driving the conveyor belt 207 to run at a constant speed and transporting the needle roller bearings that have fallen onto the conveyor belt 207. The subsequent conveyor belt... 207 precisely delivers the needle roller bearings to each workstation (such as the inspection area and the needle loading area). When the needle roller bearings arrive at the inspection area along with the conveyor belt 207, the bearing orientation detector 4 (such as a vision recognition system or Hall sensor) quickly determines the bearing installation orientation. If the orientation is incorrect, the PLC programmable controller 9 controls the robotic arm 5 to flip or remove the bearing. The robotic arm 5 adjusts its posture based on the data fed back by the detector. The needle loading device 6 grabs the needle rollers and presses them into the inner ring of the bearing according to a preset program (such as the needle roller spacing and quantity). The pressure and depth are precisely controlled by the PLC programmable controller 9. After the needle loading is completed, the needle roller bearings enter the missing needle detection area. The missing needle detector 7 (such as a laser scanner or a weighing sensor) quickly determines whether the number of needle rollers meets the standard. If a missing needle is detected, the PLC programmable controller 9 immediately triggers the following actions (suspends the production line to prevent defective products from flowing into subsequent processes, drives the robotic arm 5 to move the defective products to the external waste area, and alerts the operator by flashing the LED light strip 16 or sounding an alarm). Finally, the stainless steel plate 8 prevents oil stains from corroding the surface, the silicone pad 11 at the bottom of the support leg 10 reduces the impact of equipment vibration on detection accuracy, the LED light strip 16 provides sufficient lighting to facilitate manual intervention, and the drawer 13 is used to store spare needle rollers or tools to shorten troubleshooting time. At the same time, after the equipment has been used for a period of time, the sealing plate 308 can be removed by unscrewing the screw 309, and finally the inside of the box 303 can be cleaned.
