Description

Technical Field

[0001] The invention relates to a workpiece front and back side adjustment conveying system and a conveying method, belonging to the technical field of workpiece conveying and processing. Background Art

[0002] In the field of automotive air-conditioning compressor manufacturing, the valve plate is the core component of the compressor, and its quality and performance are directly related to the overall working efficiency, durability and cooling effect of the compressor. In particular, its surface finish is crucial to ensure smooth airflow and sealing performance inside the compressor. Generally, the valve plate of automotive air-conditioning compressors is required to meet a higher finish standard, such as 0.4Ra, to ensure stable operation of the compressor under complex and changeable working conditions.

[0003] In the current valve plate grinding process, the front and back sides of the valve plate are ground by two independent grinding wheels in the grinding machine to achieve the required surface finish. However, since the two sides of the valve plate of the automotive air-conditioning compressor often have different appearance structures, the two sides of the valve plate have significant differences in material hardness, tissue distribution, etc. Therefore, when the valve plate enters the grinding machine with different faces, the wear rate of the grinding wheel will be significantly different when it contacts the valve plate surface of different materials.

[0004] This inconsistency in wear not only shortens the service life of the grinding wheel, but more importantly, it seriously affects the consistency of valve plate grinding and the uniformity of surface finish, reducing product quality. To solve this problem, the current common method is to arrange workers on the valve plate conveyor line to conduct manual inspections, visually judging the front and back of the valve plate to ensure that the valve plate is conveyed to the grinder in the same direction.

[0005] However, this manual inspection method has obvious disadvantages. First, manual inspection is difficult to avoid missed inspections, especially on high-speed, continuous production lines. Workers' attention and judgment may be affected by factors such as fatigue and distraction, resulting in the misjudgment of the front and back of some valve plates, which in turn affects the grinding effect. Second, manual inspection is inefficient and cannot meet the needs of large-scale, high-efficiency production.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present inventive concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] The purpose of the present invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0008] The technical solution provided by the present invention is as follows: a workpiece front and back side adjustment and conveying system, comprising a front feeding mechanism, a visual inspection mechanism, a pushing mechanism, a workpiece front and back side adjustment mechanism and a rear feeding mechanism, wherein the front feeding mechanism is used to convey the workpiece to the bottom of the visual inspection mechanism;

[0009] Visual inspection mechanism: used to inspect the front and back sides of the workpiece located on the front feeding mechanism;

[0010] Pushing mechanism: used to push the workpiece from the front feeding mechanism to the workpiece front and back adjustment mechanism;

[0011] Workpiece front and back side adjustment mechanism: used to rotate the workpiece clockwise or counterclockwise to a required direction, and the turned workpiece will fall from the discharge port of the workpiece front and back side adjustment mechanism into the rear feeding mechanism below in a vertical posture;

[0012] The rear feeding mechanism is arranged below the workpiece front and back side adjustment mechanism and is used for receiving and conveying the vertical workpiece falling from the discharge port of the workpiece front and back side adjustment mechanism.

[0013] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: the front feeding mechanism of the present invention can convey the workpieces arranged in a uniform width or length direction to one side of the pushing mechanism, and the front and back sides of the workpieces located on the front feeding mechanism are detected by the visual inspection mechanism to determine whether their directions meet the requirements, and the front and back side adjustment mechanism of the workpieces can control the flipping direction according to the detection results of the visual inspection mechanism, and the flipped workpieces all fall into the rear feeding mechanism in the same direction, and are conveyed by the rear feeding mechanism to the grinding channel of the grinder in a vertical position (i.e., the workpieces are standing) for grinding, ensuring that each workpiece enters the subsequent processing equipment (such as the grinder) in the same direction, ensuring the consistency of valve plate grinding and the uniformity of surface finish. The present invention avoids manual intervention by automatically adjusting the front and back sides of the workpieces, and significantly improves production efficiency.

[0014] Based on the above technical solution, the present invention can also be improved as follows.

[0015] Furthermore, the workpiece front and back side adjustment mechanism includes a driving cylinder and a flip seat, the driving shaft of the driving cylinder is connected to the flip seat, the driving cylinder can drive the flip seat to rotate forward and / or reversely, and a straight or cross-shaped through groove is provided in the flip seat.

[0016] The beneficial effect of adopting the above further scheme is that the pushing mechanism pushes the workpiece into one opening of the straight or cross-shaped through groove, the driving cylinder drives the flip seat to rotate clockwise or counterclockwise, and the workpiece falls vertically from the other opening of the straight or cross-shaped through groove, and the workpiece front and back side adjustment mechanism can not only flip the workpiece to a vertical posture, but also ensure that the front or back direction of all workpieces remains consistent.

[0017] Furthermore, it also includes an outer sleeve, which is sleeved outside the turning seat and is provided with an inlet / outlet.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the outer sleeve enhances the stability of the workpiece during the flipping process, preventing the workpiece from accidentally falling off or shifting due to the flipping action. In addition, the outer sleeve also improves the safety of the front and back side adjustment mechanism of the workpiece, reduces the direct contact between the workpiece and other parts of the machine, and reduces the risk of workpiece damage or machine failure.

[0019] Furthermore, the rear feeding mechanism includes a belt conveyor, a first limiting plate and a second limiting plate, the first limiting plate and the second limiting plate are relatively arranged on both sides of the conveying belt of the belt conveyor, and a rear feeding trough is provided between the first limiting plate and the second limiting plate, and the upper end of the rear feeding trough is a V-shaped opening.

[0020] The beneficial effect of adopting the above further scheme is that the slot width of the rear feed slot is adapted to the width of the workpiece, and under the clamping between the first limiting vertical plate and the second limiting vertical plate, the belt conveyor can transport the workpiece vertically to subsequent processing equipment.

[0021] Furthermore, a limited height beam spans above the rear feeding chute.

[0022] The beneficial effect of adopting the above further solution is that when the workpiece is conveyed in the rear feeding trough in a state where the long side is standing, the workpiece will touch the height-limiting crossbeam above, and thus be flipped to a state where the short side is standing, and continue to be conveyed to the subsequent processing equipment. In this way, it is ensured that the workpiece can enter the subsequent processing flow in the correct direction.

[0023] Furthermore, the front feeding mechanism includes a base, a vibrating plate and a front feeding trough, the vibrating plate is installed on the base, a vibrator is provided in the base, a spiral material channel is provided in the vibrating plate, and a blocking rod is also provided on the spiral material channel. The blocking rod is used to exclude workpieces whose discharge direction does not meet the requirements, the feeding end of the front feeding trough is connected with the discharging end of the spiral material channel, and the front feeding trough is used to receive the workpiece from the vibrating plate and transport it to the feeding port side of the workpiece front and back side adjustment mechanism.

[0024] The beneficial effect of adopting the above further scheme is that the front feeding mechanism is used to orient the workpieces in a uniform width or length direction and then convey them to the front feeding trough in a horizontal posture, which can ensure that most of the workpieces have been neatly arranged and conveyed in the correct direction and posture before entering the workpiece front and back side adjustment mechanism.

[0025] Furthermore, a limiting pressure plate is provided above the front feeding chute.

[0026] The beneficial effect of adopting the above further solution is to prevent the workpiece from being affected in subsequent processing due to jumping or deviation during the conveying process.

[0027] Furthermore, the pushing mechanism includes a workbench, a motor, a turntable, a guide column and a push plate, the motor is installed below the workbench, the turntable is installed above the workbench, the driving shaft of the motor passes through the workbench and is connected to the turntable, the guide column is installed on the turntable, the push plate is installed on the workbench through a slide rail, a guide groove is provided on the push plate, and the guide column is located in the guide groove for pushing the push plate.

[0028] The beneficial effect of adopting the above-mentioned further scheme is that due to the cooperation of the guide column and the guide groove, the movement trajectory of the push plate is controlled, thereby avoiding deviations that may occur during the pushing process. The pushing mechanism can ensure that the push plate, driven by the motor, can stably and accurately push the workpiece along a predetermined path to the front and back side adjustment mechanism of the workpiece.

[0029] A method for adjusting and conveying the front and back sides of a workpiece, using the workpiece front and back side adjustment and conveying system, the method is as follows:

[0030] The workpiece is placed on the front feeding mechanism, which orients and arranges it and transports it to the bottom of the visual inspection mechanism; the visual inspection mechanism detects the front and back sides of the workpiece on the front feeding mechanism to determine whether its direction meets the requirements; the pushing mechanism pushes the workpiece from the front feeding mechanism to the workpiece front and back side adjustment mechanism; the flipping direction of the workpiece front and back side adjustment mechanism is controlled according to the detection result of the visual inspection mechanism; the flipped workpiece falls into the rear feeding mechanism and is transported by the rear feeding mechanism.

[0031] The method for adjusting and conveying the front and back sides of a workpiece provided by the present invention realizes the adjustment and conveying of the front and back sides of the workpiece, improves production efficiency, reduces the scrap rate, and optimizes the overall production process.

[0032] Furthermore, the workpiece is placed in the vibration plate of the front feeding mechanism. Under the vibration of the vibrator, the rectangular valve plate will move along the spiral material channel to the discharge end. When the valve plate is close to the discharge end, it will move with the long side or short side tilted and upright. When the valve plate moves to the position of the stop rod, the stop rod will prevent the valve plate workpiece standing with the long side from moving forward, thereby excluding workpieces whose discharge direction does not meet the requirements.

Therefore, these terms should not be understood as restrictive interpretations of the content of this application.

[0053] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0054] Embodiment 1:

[0055] like Figure 1 and Figure 2As shown, a workpiece front and back side adjustment and conveying system comprises a front feeding mechanism 100, a visual inspection mechanism 200, a pushing mechanism 300, a workpiece front and back side adjustment mechanism 400 and a rear feeding mechanism 500, wherein the front feeding mechanism 100 is used to orient the workpieces in a uniform width or length direction and convey them horizontally to the bottom of the visual inspection mechanism 200; the visual inspection mechanism 200 is used to detect the front and back sides of the workpieces located on the front feeding mechanism 100; the pushing mechanism 300 is used to push the workpieces from the front feeding mechanism 100 to the rear feeding mechanism 500; The feeding mechanism 100 pushes the workpiece into the workpiece front and back side adjustment mechanism 400; the workpiece front and back side adjustment mechanism 400 is used to rotate the workpiece clockwise or counterclockwise to the required direction, and the flipped workpiece will fall from the discharge port 432 of the workpiece front and back side adjustment mechanism 400 into the rear feeding mechanism 500 below in a vertical posture; the rear feeding mechanism 500 is arranged below the workpiece front and back side adjustment mechanism 400, and is used to receive and convey the workpiece in a vertical state falling from the discharge port 432 of the workpiece front and back side adjustment mechanism 400.

[0056] More specifically, the workpiece front and back side adjustment mechanism 400 includes a drive cylinder 410, a flip seat 420 and an outer sleeve 430. The drive shaft of the drive cylinder 410 is connected to the flip seat 420. The drive cylinder 410 can drive the flip seat 420 to rotate forward and reverse. Figure 8 As shown, the flip seat 420 is provided with a cross-shaped through groove 421, the outer sleeve 430 is sleeved outside the flip seat 420, and the outer sleeve 430 is provided with two inlet / outlet ports, one of which is a feed port 431, and the other is a discharge port 432. The central angle between the feed port 431 and the discharge port 432 is set at an angle of 90°. The outer sleeve 430 is fixedly mounted on the cylinder body of the driving cylinder 410, or mounted on the frame, and the flip seat 420 can rotate in the outer sleeve 430. The pushing mechanism 300 pushes the workpiece from the feed port 431 into the cross-shaped through groove 421, and the driving cylinder 410 drives the flip seat 420 to rotate clockwise or counterclockwise, and the workpiece falls vertically from the discharge port 432 along the cross-shaped through groove 421, ensuring that the workpiece can maintain a stable posture during the flipping process. An end cover is provided at the end of the outer sleeve 430, which enhances the stability of the workpiece during the flipping process and prevents the workpiece from accidentally falling off or shifting due to the flipping action. In addition, the outer sleeve 430 also improves the safety of the workpiece front and back side adjustment mechanism 400, reduces the direct contact between the workpiece and other parts of the machine, and reduces the risk of workpiece damage or machine failure.

[0057] The rear feeding mechanism 500 includes a belt conveyor 501, a first limit plate 502 and a second limit plate 503. The first limit plate 502 and the second limit plate 503 are arranged on both sides of the conveying belt of the belt conveyor 501. A rear feeding trough 504 is arranged between the first limit plate 502 and the second limit plate 503. The upper end of the rear feeding trough 504 is V-shaped and convenient for receiving workpieces. The trough width of the rear feeding trough 504 is adapted to the width of the workpiece. Under the clamping between the first limit plate 502 and the second limit plate 503, the belt conveyor 501 can vertically transport the workpiece to the subsequent processing equipment.

[0058] When the workpiece falls into the rear feed trough 504 from the workpiece front and back adjustment mechanism 400, when the corner of the workpiece first contacts the conveyor belt of the belt conveyor 501, in this process, the workpiece may flip to a state where the long side stands. However, if the workpiece continues to be conveyed in the rear feed trough 504 in a state where the long side stands, its direction will not meet the requirements of subsequent processing. In order to solve this problem, when the workpiece passes through the rear feed trough 504 in an incorrect direction (i.e., the long side stands), it will touch the height-limiting beam 505 above, and the height-limiting beam 505 will cause the workpiece to flip, so that it changes from a state where the long side stands to a state where the short side stands. Subsequently, the workpiece will continue to be conveyed to subsequent processing equipment in the correct direction. The height-limiting beam 505 ensures that the workpiece can enter the subsequent processing flow in the correct direction, thereby improving the accuracy and efficiency of the processing.

[0059] The front feeding mechanism 100 includes a base 110, a vibration plate 120 and a front feeding trough 130. The vibration plate 120 is mounted on the base 110. A vibrator is disposed in the base 110. A spiral material channel is disposed in the vibration plate 120. Fig.10 As shown, the spiral material channel is also provided with a blocking rod 121, which is used to exclude workpieces whose discharging direction does not meet the requirements, and the feeding end of the front feeding trough 130 is connected to the discharging end of the spiral material channel, and the front feeding trough 130 is used to receive the workpieces from the vibration plate 120 and convey them to the feeding port side of the workpiece front and back adjustment mechanism 400. The front feeding mechanism 100 is used to orient the workpieces in a uniform width or length direction and convey them to the front feeding trough 130 in a horizontal posture, which can ensure that most of the workpieces have been neatly arranged and conveyed in the correct direction and posture before entering the workpiece front and back adjustment mechanism 400.

[0060] A limiting pressure plate 131 is provided above the front feeding trough 130 to prevent the workpiece from bouncing or deviating during the conveying process and affecting subsequent processing.

[0061] The pushing mechanism 300 includes a workbench 301, a motor 302, a turntable 303, a guide column 304 and a push plate 305. The motor 302 is installed below the workbench 301, the turntable 303 is installed above the workbench 301, the driving shaft of the motor 302 passes through the workbench 301 and is connected to the turntable 303, the guide column 304 is installed on the turntable 303, the push plate 305 is installed on the workbench 301 through a slide rail, and a guide groove is provided on the push plate 305. The guide column 304 is located in the guide groove and is used to push the push plate 305. When the motor 302 drives the turntable 303 to rotate, the guide column 304 can move along the guide groove, thereby pushing the push plate 305 to move forward and backward along the slide rail. The guide column 304 will drive the push plate 305 to move forward or backward along the slide rail. Due to the cooperation between the guide column 304 and the guide groove, the movement trajectory of the push plate 305 is controlled, avoiding possible deviations during the pushing process. The pushing mechanism 300 can ensure that the push plate 305 is driven by the motor 302 to stably and accurately push the workpiece along a predetermined path to the workpiece front and back adjustment mechanism 400.

[0062] like Figure 3 - Figure 6 As shown, a workpiece front and back side adjustment grinding system includes a grinder 600 and the workpiece front and back side adjustment conveying system. The grinder 600 includes a first grinding wheel 601 and a second grinding wheel 602. A grinding channel is provided between the first grinding wheel 601 and the second grinding wheel 602. The rear feeding mechanism 500 conveys the workpiece into the grinding channel in a vertical posture. The grinding channel provides a space for the workpiece to perform surface grinding treatment. The rear feeding mechanism 500 conveys the workpiece into the grinding channel in a vertical manner (i.e., the workpiece is in a standing state), ensuring that the workpiece can contact the grinding wheel at an appropriate angle and position, thereby performing effective grinding treatment.

[0063] A method for adjusting and conveying the front and back sides of a workpiece, using the workpiece front and back side adjustment and conveying system, the method is as follows: placing the workpiece on a front feeding mechanism 100, which orients and arranges the workpiece and conveys it to the bottom of a visual inspection mechanism 200; the visual inspection mechanism 200 inspects the front and back sides of the workpiece on the front feeding mechanism 100 to determine whether its direction meets the requirements; a pushing mechanism 300 pushes the workpiece from the front feeding mechanism 100 to the workpiece front and back side adjustment mechanism 400; the flipping direction of the workpiece front and back side adjustment mechanism 400 is controlled according to the detection result of the visual inspection mechanism 200; the flipped workpiece falls into a rear feeding mechanism 500 and is conveyed by the rear feeding mechanism 500.

[0064] The following takes the conveying of a rectangular valve plate 700 workpiece as an example to introduce in detail the conveying method of adjusting the conveying system by using the front and back sides of the workpiece:

[0065] The workpiece is placed in the vibration plate 120 of the front feeding mechanism 100. Under the vibration of the vibrator, the rectangular valve plate 700 will move along the spiral channel toward the discharge end. When the valve plate 700 approaches the discharge end, they may move with the long side or the short side tilted and upright. Fig.10 As shown, when the valve plate 700 moves to the position of the blocking rod 121, the blocking rod 121 will prevent the valve plate 700 workpiece that stands up with its long side (higher height) from continuing to move forward, thereby excluding workpieces whose discharge direction does not meet the requirements. The long side of the valve plate 700 is parallel to the conveying direction of the front feed trough 130, and the front feed trough 130 conveys the valve plate 700 in a horizontal posture in a uniform length direction to the bottom of the visual inspection mechanism 200.

[0066] The visual inspection mechanism 200 is responsible for inspecting the front and back sides of the workpiece located on the front feeding mechanism 100 , that is, determining whether the front side or the back side of the valve plate 700 is facing upward.

[0067] Next, the push mechanism 300 starts to work. When the workpiece needs to be pushed, the motor 302 is started to drive the turntable 303 to rotate. The guide post 304 on the turntable 303 moves along the guide groove on the push plate 305 as it rotates. Under the action of the guide post 304, the push plate 305 moves along the predetermined path and pushes the workpiece from the front feed trough 130 to the cross-shaped through groove 421. When the motor 302 is reversed, the push plate 305 will reset in the reverse direction and wait for the next round of operation.

[0068] According to the detection result of the visual detection mechanism 200, the system will control the rotation direction of the workpiece front and back adjustment mechanism 400. Figure 1 As shown, when the front side of the valve plate 700 faces upward, the drive cylinder 410 will drive the flip seat 420 to rotate 90° clockwise, and when the valve plate 700 falls into the rear feed trough 504 from the discharge port 432, its front side will stand to the right in the rear feed trough 504 for transportation. On the contrary, when the back side of the valve plate 700 faces upward, the drive cylinder 410 will drive the flip seat 420 to rotate 90° counterclockwise to ensure that when the valve plate 700 falls into the rear feed trough 504 from the discharge port 432, its front side also faces to the right. Therefore, the workpiece front and back side adjustment mechanism 400 can not only flip the workpiece to a vertical posture, but also ensure that the front or back side of all workpieces remain consistent. The cross-shaped through groove 422 is used so that there is no need to reversely flip and reset after the flip seat 420 flips and drops the material.

[0069] Finally, the turned-over valve plate 700 falls into the rear feeding mechanism 500 and is transported by the rear feeding mechanism 500 to the grinding channel of the grinder 600 for grinding.

[0070] Of course, the present invention can also convey workpieces of other shapes such as round, square, etc. The conveying method is similar to the method of conveying the rectangular valve plate 700, which will not be repeated here.

[0071] The workpiece front and back side adjustment and conveying system of the present invention can not only ensure that the front side of each valve plate 700 faces the grinding wheel on the same side, thereby ensuring the consistency of the grinding of the valve plate 700 and the uniformity of the surface finish; at the same time, by automatically adjusting the front and back sides of the workpiece, manual intervention is avoided and production efficiency is improved.

[0072] Embodiment 2:

[0073] like Figure 8 As shown, the difference between this embodiment and the first embodiment is that a straight through groove 422 is provided in the flip seat 420, and both ends of the straight through groove 422 are connected. The other structures of this embodiment are the same as those of the first embodiment, and will not be repeated here.

[0074] The working method of the workpiece front and back side adjustment mechanism 400 of the present embodiment is as follows: the pushing mechanism 300 pushes the valve plate 700 from one end of the I-shaped through groove 422 into the I-shaped through groove 422. When the front side of the valve plate 700 faces upward, the driving cylinder 410 drives the flip seat 420 to rotate 90° clockwise. When the valve plate 700 falls into the rear feeding trough 504 from the discharge port 432, its front side will stand to the right in the rear feeding trough 504 for transportation. Subsequently, the driving cylinder 410 drives the flip seat 420 to rotate 90° counterclockwise to reset and wait for the next flip plate. On the contrary, when the back side of the valve plate 700 faces upward, the driving cylinder 410 drives the flip seat 420 to rotate 90° counterclockwise to reset and wait for the next flip plate.

[0075] Embodiment three:

[0076] like Fig. 9 As shown, the difference between this embodiment and the first embodiment is that the outer sleeve 430 and the cross groove flip seat 420 are both mounted on the driving shaft of the driving cylinder 410, and the outer sleeve 430 rotates synchronously with the cross groove flip seat 420. The outer sleeve 430 is provided with four inlet / outlet ports. The other structures of this embodiment are the same as those of the first embodiment and are not repeated here. The outer sleeve 430 rotates synchronously with the cross groove flip seat 420, so that the workpiece front and back adjustment mechanism 400 has greater flexibility and adaptability, and the rotation angle of the outer sleeve 430 and the flip seat 420 can be adjusted according to actual needs, so as to meet different workpiece flipping and conveying requirements. Whether the outer sleeve 430 is fixedly installed or rotates synchronously with the flip seat 420, it can be selected according to actual needs to meet different application scenarios and workpiece flipping requirements.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
