Description

Technical Field

[0001] This invention belongs to the field of housing assembly technology, specifically relating to an assembly device for a pressure sensor housing and its operating method. Background Technology

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable electrical signals according to certain rules.

[0003] Pressure sensors typically consist of a pressure-sensitive element, a device that converts the force or motion generated by the pressure-sensitive element into electrical parameters, and a device that displays or records the electrical parameters. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. They are widely used in various industrial automation environments, involving many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, power, shipbuilding, machine tools, and pipelines.

[0004] To ensure reliable sealing under various operating conditions, prevent media leakage, and maintain cost-effectiveness and ease of maintenance, O-rings are commonly installed inside pressure sensors.

[0005] In order to form an effective seal between the screw and the housing and prevent liquid or gas leakage, an O-ring is first put on the screw, and then the screw is pressed and riveted to the housing. When the screw is pressed and riveted to the housing, the O-ring is compressed, generating sufficient sealing force to prevent the medium from leaking.

[0006] However, in the current technology, the installation of O-rings and the operation of putting O-rings on screws are all done manually, which requires a lot of manpower. Summary of the Invention

[0007] In view of the above-mentioned problems in the prior art, the object of the present invention is to provide an assembly device for a pressure sensor housing and a method for operating the same.

Subsequently, the workpiece is unloaded onto the flipping assembly, which flips the workpiece to the back side and simultaneously feeds it into the large turntable assembly. The workpiece sequentially undergoes sixth detection, seventh detection, eighth detection, ninth detection, screw and O-ring installation, tenth detection, eleventh detection, twelfth detection, thirteenth detection, fourteenth detection, fifteenth detection, and sixteenth detection.

[0075] Example 1

[0076] like Figure 1As shown, the present invention provides an assembly device for a pressure sensor housing, including a worktable 1, and a feeding assembly 3, a small turntable assembly 2, a flipping assembly 9, a large turntable assembly 4, a discharging assembly 5, a stacking assembly 6, and a robot 10 mounted on the worktable 1. The workpiece enters the small turntable assembly 2 from the feeding assembly 3, and sequentially undergoes laser marking, resistance testing, first detection, second detection, third detection, O-ring loading, fourth detection, and fifth detection on the small turntable assembly 2. Subsequently, the workpiece is discharging onto the flipping assembly 9, which flips the workpiece to the back side and simultaneously feeds it into the large turntable assembly 4. The workpiece sequentially undergoes sixth detection, seventh detection, eighth detection, ninth detection, screw and O-ring installation, tenth detection, eleventh detection, twelfth detection, thirteenth detection, fourteenth detection, fifteenth detection, and sixteenth detection. Finally, the discharging assembly 5 discharges the workpiece, and the robot 10 moves the workpiece into the stacking assembly 6 for stacking.

[0077] Please refer to this carefully. Figure 3 The small turntable assembly 2 includes a small indexing plate 208, on which are evenly distributed laser marking and resistance testing stations 201, a first inspection station 202, a second inspection station 203, a third inspection station 204, an O-ring loading station 205, a fourth inspection station 206, a fifth inspection station 210, and a unloading station 207. Each station is equipped with a fixture 209 corresponding to the laser marking and resistance testing station 201 and the laser marking and resistance testing components mounted on the worktable 1, corresponding to the first inspection station 204. Camera component 1, located at position 202 and mounted on workbench 1, corresponds to camera component 2, located at second inspection station 203 and mounted on workbench 1. Camera component 2, located at third inspection station 204 and mounted on workbench 1, corresponds to O-ring feeding station 205 and mounted on workbench 1. Camera component 3, located at fourth inspection station 206 and mounted on workbench 1, corresponds to camera component 4, located at fifth inspection station 210 and mounted on workbench 1. The flipping component 9 corresponds to the position of unloading station 207.

[0078] The workpiece is fed into the laser marking and resistance testing assembly via the feeding component 3 for laser marking and resistance testing. Subsequently, the workpiece is sent to the first inspection station 202, where the front end face of the workpiece is photographed and inspected by camera component 1 to check for marks and dents. Please refer to the following for details. Figure 2The workpiece is then sent to the second inspection station 203, where camera assembly 2 inspects the blue rivets 11 on the workpiece. For a qualified workpiece, there are four blue rivets 11, located at the four corners of the workpiece end face. Camera assembly 2 takes pictures to check if there are four blue rivets 11, whether their positions are correct, whether their condition is good, and whether there are scratches or burrs. After that, the workpiece is sent to the third inspection station 204, where camera assembly 2 inspects the black rivets 12 on the workpiece. For a qualified workpiece, there are two black rivets 12, located on both sides of the middle position of the workpiece. Camera assembly 2 takes pictures to check if there are two black rivets 12, whether their positions are correct, whether their condition is good, and whether there are scratches or burrs. After that, the workpiece is sent to the O-ring loading station 205, where the O-ring loading assembly places the O-rings into the O-ring placement holes 7 of the workpiece.

[0079] The workpiece is sent to the fourth inspection station 206, where camera component three checks whether a QR code exists. The workpiece is then sent to the fifth inspection station 210, where camera component four checks whether an O-ring exists in the workpiece. If it exists, the O-ring will protrude from the end face of the workpiece. Camera component four takes a picture from the side to observe whether the O-ring exists. After that, the workpiece is sent to the unloading station 207, where the flipping component 9 removes the workpiece.

[0080] Please refer to this carefully. Figure 5 and 6 The feeding assembly 3 includes a single-axis robot 305, on which a tooling 209 is mounted. One end of the single-axis robot 305 is surrounded by a limiting frame 301. A safety light curtain 302 and a photoelectric sensor 303 are installed on the inner wall of the limiting frame 301. The safety light curtain 302 is used to detect the worker's insertion action, and the photoelectric sensor 303 is used to detect whether the workpiece is in place. An alarm light 306 and a button 304 are respectively installed on both sides of the limiting frame 301. A photoelectric sensor 307 is provided at the other end of the single-axis robot 305.

[0081] In the initial state, fixture 209 is located within the limiting frame 301. The workpiece is placed in fixture 209 by a person. At this time, safety light curtain 302 senses the placement action, and photoelectric sensor 303 senses the workpiece and transmits a signal to start single-axis robot 305, which then delivers the workpiece to the other end. If only safety light curtain 202 senses the placement action, but photoelectric sensor 303 does not detect the workpiece, alarm light 306 will sound an alarm to notify the staff to check. If an accident occurs during transportation, the staff can press button 304 to stop the single-axis robot 305 from continuing to transport the workpiece.

[0082] Please refer to this carefully. Figure 5The laser marking and resistance testing assembly includes a mounting bracket 2012 mounted on a workbench 1, a three-axis module 1 2013 mounted inside the mounting bracket 2012, a laser marking and resistance testing machine 2011 mounted on the mounting bracket 2012, and a finger clamp cylinder 4 2014 mounted on the three-axis module 1 2013.

[0083] When photoelectric sensor 2 307 senses the workpiece, the three-axis module 1 2013 drives the finger clamp cylinder 4 2014 to move to the workpiece. The finger clamp cylinder 4 2014 clamps the workpiece and then moves it into the laser marking and resistance testing machine 2011 for laser marking and resistance testing.

[0084] Please refer to this carefully. Figure 7 The camera assembly includes a bracket 2021 mounted on a worktable 1, an aperture 2022 and a camera 2023 mounted on the bracket 2021.

[0085] Please refer to this carefully. Figure 8 Camera assembly two includes a support frame 2032 mounted on the worktable 1. A condenser 2031 and camera two 2034 are movably mounted on the support frame 2032 via a slide rail 2033. An aperture two 2035 is mounted on the bottom of the condenser 2031. The use of the condenser 2031 allows light to be concentrated into a smaller area, increasing the brightness of a specific area, thereby facilitating the detection of the condition of the blue rivet 11 and the black rivet 12.

[0086] Please refer to this carefully. Figure 9-11 The O-ring feeding assembly includes an O-ring discharging component and a transfer component mounted on the worktable 1, as well as a limiting component mounted on the small indexing plate 208. The O-ring discharging component discharges the O-rings, and then the transfer component picks up the O-rings and places them through the limiting component into the O-ring placement hole 7 of the workpiece.

[0087] The O-ring discharge component includes a vibrating disc 2051, an inlet channel 2052 connected to the discharge port of the vibrating disc 2051, a fixed column 2056 located at the other end of the inlet channel 2052 and installed on the workbench 1, and a shelf 2058 movably mounted on the fixed column 2056 via a slide cylinder 2057. The shelf 2058 is provided with a groove 2059 for placing O-rings.

[0088] The O-ring is output from the feed channel 2052 to the groove 2059. Then, the slide cylinder 2057 is activated, which causes the slide cylinder 2057 to move the shelf 2058 to the side. At this time, the outer wall of the shelf 2058 abuts against the O-ring on the rear side, preventing the subsequent O-ring from being driven out of the feed channel 2052. At the same time, the transfer component sucks away the O-ring placed in the groove 2059 and transfers it to the workpiece through the limiting component.

[0089] The transfer assembly includes a frame 2053 mounted on a worktable 1, and a suction head 2055 mounted on the frame 2053 via a three-axis module 2054.

[0090] When the slide cylinder 2057 moves the shelf 2058 to the side, the suction head 2055 picks up the O-ring in the groove 2059.

[0091] The limiting assembly includes a limiting tube 20511 mounted on the small indexing plate 208 via a three-axis module 20510.

[0092] The three-axis module 20510 moves the limiting tube 20511 to directly above the O-ring placement hole 7. The limiting tube 20511 restricts the movement of the O-ring, ensuring that the O-ring falls into the O-ring placement hole 7. After the suction head 2055 picks up the O-ring, it moves the O-ring through the limiting tube 20511 and into the O-ring placement hole 7. Then, the suction head 2055 is closed, and the three-axis module 2054 moves the suction head 2055 to press the O-ring firmly into the O-ring placement hole 7, thus preventing the O-ring from falling out.

[0093] Please refer to this carefully. Figure 12 The camera assembly includes a camera bracket 2064 mounted on the worktable 1, a camera 2065 and an aperture 2063 mounted on the camera bracket 2064, and a cylinder 2062 mounted on the small indexing plate 208 via a cylinder mounting seat 2061.

[0094] After the O-ring is placed, cylinder 2062 presses the workpiece down, and then camera 2065 takes a picture of the QR code on the side of the workpiece to check if the QR code exists.

[0095] Please refer to this carefully. Figure 13 The camera assembly 4 includes a backlight plate bracket 2101 mounted on the workbench 1, a backlight plate 2102 mounted on the backlight plate bracket 2101, and the camera 4 2104 mounted on the small indexing plate 208 via a camera mounting base 2103.

[0096] The backlight panel 2102 is used to ensure uniform illumination and avoid uneven brightness or local over-brightness or under-brightness, so as to more clearly capture whether an O-ring is placed inside the workpiece.

[0097] Please refer to this carefully. Figure 14The flipping assembly 9 includes a finger gripper cylinder 902 mounted on the worktable 1 via a two-axis module 901, a finger gripper cylinder 905 mounted on the worktable 1 via a two-axis module 904, and a flipping component 903 mounted on the worktable 1. The two-axis modules 901 and 904 are placed perpendicularly, and the flipping component 903 is located at the intersection of the two-axis modules 901 and 904. The combination of the two-axis modules 901 and 904 can form a three-axis module. For example, if the two-axis module 901 is an XZ-axis module, then the two-axis module 904 is a YZ-axis module. If the two-axis module 901 is a YZ-axis module, then the two-axis module 904 is an XZ-axis module.

[0098] The finger-grip cylinder 902 on the two-axis module 901 moves the workpiece from the small indexing plate 208 to the flipping component 903, and the finger-grip cylinder 905 on the two-axis module 904 moves the workpiece from the flipping component 903 to the large turntable assembly 4.

Figure 15 The flipping component 903 includes a flipping bracket 9031 that is movably mounted on the worktable 1 via a moving cylinder 9031 and a linear guide rail 9033. To make the movement of the flipping bracket 9031 more stable, the flipping bracket 9031 is also movably mounted on the worktable 1 via a drag chain 9034. The rotating plate 9038 is movably mounted on the flipping bracket 9031 via a rotating cylinder 9037. The finger clamp cylinder 9039 is mounted on the rotating plate 9038. At the same time, the rotating plate 9038 is provided with a limiting hole 90310.

[0100] The finger clamp cylinder 902 moves the workpiece from the small indexing plate 208 to the limiting hole 9031. At this time, the finger clamp cylinder 9039 is activated, clamping the workpiece. The finger clamp cylinder 902 releases the workpiece, and the two-axis module 901 drives it to return to its original state. Then, the rotary cylinder 9037 is activated, thereby causing the workpiece to flip over.

[0101] Furthermore, photoelectric sensor 3 90311 is mounted on the flip bracket 9031, and photoelectric sensor 3 90311 is located directly below the limiting hole 90310, used to sense whether the workpiece is accurately placed in the limiting hole 90310.

[0102] When the photoelectric sensor 390311 senses the workpiece, it transmits a signal to activate the finger clamp cylinder 39039, thereby clamping the workpiece.

[0103] The flipping bracket 9031 consists of a base plate 9035 and two side plates 9036, with the side plates 9036 mounted on both sides of the base plate 9035. The base plate 9035 is mounted on a linear guide rail 9033, and one side plate 9036 is mounted on a moving cylinder 9032.

[0104] Please refer to this carefully. Figure 16 The large turntable assembly 4 includes a large indexing plate 401, on which are evenly distributed the following stations: loading station 402, sixth inspection station 403, seventh inspection station 404, eighth inspection station 405, ninth inspection station 406, screw and O-ring installation station 407, tenth inspection station 408, eleventh inspection station 409, twelfth inspection station 410, thirteenth inspection station 411, fourteenth inspection station 412, fifteenth inspection station 413, sixteenth inspection station 414, and unloading station 415. Each station is equipped with a tooling fixture 209. The flipping assembly 9 corresponds to the loading station 402, and to the sixth inspection station 403, seventh inspection station 404, eighth inspection station 405, ninth inspection station 406, screw and O-ring installation station 407, tenth inspection station 408, eleventh inspection station 409, twelfth inspection station 410, thirteenth inspection station 411, fourteenth inspection station 412, fifteenth inspection station 413, sixteenth inspection station 414, and unloading station 415. Camera assembly 5, which is installed on worktable 1 at inspection stations 404, 405, and 406, corresponds to the screw and O-ring assembly installed on worktable 1 at screw and O-ring station 407, and is installed on worktable 1 at inspection stations 408, 409, and 410, respectively. Camera assembly 6, which is installed on worktable 1 at inspection stations 411, 412, and 413, corresponds to the camera assembly installed on worktable 1 at inspection stations 413 and 414, respectively. The unloading assembly 5 is located at the unloading station 415.

[0105] After being flipped by the flipping component 9, the workpiece is fed into the loading station 402 on the large indexing plate 401. Then, the workpiece is sent to the sixth inspection station 403, where the back of the workpiece is inspected by the camera component 5 to check for cracks and damage. Next, the workpiece is sent to the seventh inspection station 404, where the QR code on the back of the workpiece is inspected by the camera component 5; misaligned, incomplete, or illegible codes are not allowed. Afterward, the workpiece is sent to the eighth inspection station 405, where the terminals on the workpiece are inspected by the camera component 5; bent terminals and contaminants are not allowed. Next, the workpiece is sent to the ninth inspection station 406, where the glue application is inspected by the camera component 5; insufficient or missing glue is not allowed. Finally, the workpiece is sent to the screw and O-ring installation station 407, where screws and O-rings are installed using the screw and O-ring installation component.

[0106] The tenth inspection station 408, the eleventh inspection station 409, the twelfth inspection station 410, the thirteenth inspection station 411, and the fourteenth inspection station 412 are all used to inspect the side of the workpiece, respectively checking whether there are gaps, cracks, and scratches on the workpiece shell; then the workpiece is sent to the fifteenth inspection station 413, where the camera assembly six checks whether there are white spots on the workpiece plug; then the workpiece is sent to the sixteenth inspection station 414, where the camera assembly six checks whether the movement affects the workpiece; finally, the workpiece is sent to the unloading station 415, where the unloading assembly 5 moves the workpiece out of the large turntable assembly 4.

[0107] Camera assembly five is similar to camera assembly two, but the position of the condenser 2031 is different. The condenser 2031 of camera assembly five is placed at an angle and is facing the position to be photographed, thereby concentrating the light on the position to be detected.

[0108] Please refer to this carefully. Figure 17-20 The screw and O-ring assembly includes an O-ring feeding assembly, an O-ring moving assembly, a transition assembly 40717, an O-ring transfer assembly, a screw feeding assembly, and a screw transfer assembly, all mounted on the worktable 1. The O-ring moving assembly transfers the O-ring from the O-ring feeding assembly to the O-ring transfer assembly, while the transition assembly 40717 prevents the O-ring from falling off. Subsequently, the screw transfer assembly moves the screw from the screw feeding assembly to the O-ring transfer assembly, and then places the O-ring onto the screw. Please refer to the following for details. Figure 3 Then, the O-ring transfer assembly presses the screw with the O-ring into the riveting position 8 of the workpiece.

[0109] The O-ring feeding assembly includes a vibratory feeder 4071 and a small O-ring feeding channel 4072 connected to the outlet of the vibratory feeder 4071. A guide plate 40719 is connected to the other end of the small O-ring feeding channel 4072. The guide plate 40719 is mounted on the workbench 1 via a support column 40718. The guide plate 40719 has a vertical channel 40720 and a horizontal channel 40722, forming a T-shaped channel. The vertical channel 40720 is equal to the maximum diameter of the small O-ring, and the horizontal channel 40722 is smaller than the maximum diameter of the small O-ring, preventing the O-ring from moving into the horizontal channel 40722 during movement. When the O-ring moves to the end of the vertical channel 40720, the movement of the small O-ring is restricted by the inner wall of the guide plate 40719. At the same time, proximity switches 40721 are installed on both sides of the guide plate 40719. The proximity switches 40721 are located in the horizontal channel 40722. The proximity switches 40721 are used to detect whether the workpiece has moved to the end of the vertical channel 40720. The design of the horizontal channel 40722 is to avoid interfering with the sensing signal of the proximity switches 40721. At the intersection of the vertical channel 40720 and the horizontal channel 40722, there is a through hole. The diameter of the through hole is smaller than the maximum diameter of the small O-ring to prevent the small O-ring from falling out of the guide plate 40719 from the through hole.

[0110] The O-ring moving assembly includes an XZ axis module 4073, a second cylinder 4074 mounted on the XZ axis module 4073, and a first fixed plate 4075. The second cylinder 4074 is connected to a first moving plate 4077 via a first limiting post 4076, and the first limiting post 4076 passes through the first fixed plate 4075. A first fixed post 4079 is mounted on the first fixed plate 4075, and a first moving post 4078 is mounted on the first moving plate 4077, and the first fixed post 4079 passes through the first moving plate 4077 and the first moving post 4078.

[0111] When the small O-ring moves to the through hole, the XZ axis module 4073 drives the fixed post 4079 to pass through the through hole, thereby putting the small O-ring on the fixed post 4079, and then moves with the small O-ring to the transition component 40717.

[0112] The transition assembly 40717 includes a transition bracket 40723, a positioning post 40724 mounted on the transition bracket 40723, and a push rod 40725 movably mounted on the transition bracket 40723 by a push cylinder 40726. The positioning post 40724 passes through the push rod 40725, and the top of the positioning post 40724 is provided with a concave groove. The top of the push rod 40725 is split into several strip-shaped elastic blocks, and the several strip-shaped elastic blocks all retract into the inside of the push rod 40725.

[0113] When the XZ axis module 4073 moves the fixed post 4079 with the small O-ring to the transition component 40717, the fixed post 4079 is placed in the concave groove of the positioning post 40724. Then, the push cylinder 40726 is activated, and the push cylinder 40726 drives the push rod 40725 to push the small O-ring along the length of the fixed post 4079, thereby preventing the small O-ring from falling off the fixed post 4079. Then, the XZ axis module 4073 drives the fixed post 4079 to disengage from the positioning post 40724.

[0114] The O-ring transfer assembly includes an electric guide rail 40710, a cylinder 40711 and a fixed plate 40713 mounted on the electric guide rail 40710, and a movable plate 40714 mounted on the cylinder 40711 via a limiting post 40712. The limiting post 40712 passes through the fixed plate 40713. A fixed post 40715 is mounted on the fixed plate 40713, and a movable post 40716 is mounted on the movable plate 40714. The fixed post 40715 passes through the movable post 40716 and the movable plate 40714.

[0115] Furthermore, the number of fixed columns 2 40715 is two, and the number of movable columns 2 40716 corresponds to the number of fixed columns 2 40715.

[0116] After the first fixed post 4079 disengages from the positioning post 40724, the third cylinder 40711 is located at the end of the electric guide rail 40710 near the O-ring moving assembly. The second fixed post 40715 is also provided with a concave groove for positioning the first fixed post 4079. First, the XZ axis module 4073 drives the first fixed post 4079 with the small O-ring to move to the second fixed post 40715. Then, the second cylinder 4074 is activated, and the second cylinder 4074 drives the first moving post 4078 to move down, moving the small O-ring onto the second fixed post 40715. Then, the XZ axis module 4073 drives the first fixed post 4079 to return to its original state, repeating the operation of taking the small O-ring, thereby putting the small O-ring onto the other second fixed post 40715.

[0117] The screw feeding assembly includes a screw vibratory feeder, a screw feeding channel, and a screw placement fixture 40727 that connects to the screw feeding channel. The screw placement fixture 40727 is mounted on the feeding fixing rod 40727 by a left and right moving cylinder 40728. Two placement holes 40728 are symmetrically provided on the screw placement fixture 40727.

[0118] The screw is fed from the screw feed channel into the placement hole 40728 of the screw placement fixture 40727 by the screw vibratory feeder. When one of the placement holes 40728 is filled with a screw, the left and right moving cylinder 40728 is activated. The left and right moving cylinder 40728 drives the screw placement fixture 40727 to move, so that the other placement hole 40728 is aligned with the screw feed channel, so that screws are placed in both placement holes 40728.

[0119] The screw transfer assembly includes a module bracket 40730, a three-axis module 40729 mounted on the inner wall of the module bracket 40730, a suction cup 40731 symmetrically mounted on the three-axis module 40729, and a screw feeding assembly placed below the suction cup 40731.

[0120] The suction cup 40731 picks up the screw in the placement hole 40728, and then the three-axis module 40729 moves the screw to the fixing post 40715. The screw is placed on the concave groove of the fixing post 40715. The cylinder 3 40711 is activated, and the cylinder 3 40711 drives the moving post 40716 to move upward, thereby moving the small O-ring on the fixing post 40715 onto the screw. Then, the three-axis module 40729 moves the screw with the small O-ring to the riveting position and presses the screw into the riveting position. At this time, the screw and O-ring installation operation is completed on the workpiece.

[0121] Camera assembly six and camera assembly three, but camera assembly six does not include cylinder 2062 for pressing the workpiece.

[0122] Please refer to this carefully. Figure 21 Camera assembly seven includes a detection bracket 4081, a filter 4083 mounted on the detection bracket 4081, and a camera 4082. Filter 4083 can improve image contrast and make details clearer.

[0123] Please refer to this carefully. Figure 22 The unloading component 5 includes a horizontal single-axis robot 502 and a transfer component 501. The horizontal single-axis robot 502 is equipped with a workpiece fixture, and the transfer component 501 is used to move the workpiece to the workpiece fixture on the horizontal single-axis robot 502. The horizontal single-axis robot 502 moves the workpiece fixture to one end close to the robot arm 10.

[0124] Please refer to this carefully. Figure 23The stacking assembly 6 includes mounting brackets 601 symmetrically mounted on the workbench 1. Each mounting bracket 601 is equipped with an electric lead screw 602, and a shelf is mounted on the electric lead screw 602. A motor 603 is mounted on the mounting bracket 601, and a drive wheel 604 is mounted on the motor 603. The drive wheel 604 meshes with a driven wheel for transmission, and the driven wheel is movably mounted on the mounting bracket 601. The drive wheel 604 and the driven wheel are respectively connected to two positioning frames 607 through a transmission assembly. The two positioning frames 607 are placed symmetrically, and the positioning frames 607 are movably placed on the positioning frame support frame. A convergence triangular rod is also mounted on the positioning frame 607. When the motor 603 is turned on, the two positioning frames 607 move towards each other, thereby driving the convergence triangular rod to position the material tray 608.

[0125] The robotic arm 10 is equipped with both a large suction cup for picking up the material tray 608 and a clamping cylinder for clamping the workpiece.

[0126] Empty trays are stacked on one side of the shelf. When the operation starts, the robot arm 10 first moves an empty tray to the shelf on the other side. At the same time, the electric screw 602 drives the shelf on one side to rise to the height of one tray, so as to ensure that the empty tray is always at the same height, which is convenient for the robot arm 10 to pick up and put down later. At this time, the motor 603 is turned on, and the motor 603 drives the convergence triangular rod to position the tray 608, ensuring that the tray 608 is in the middle position of the shelf, so that the robot arm 10 can place qualified workpieces in the tray 608 in a regular manner.

[0127] The transmission assembly includes an idler wheel 605 movably mounted on a mounting bracket 601. The idler wheel 605 is connected to the drive wheel 604 or the driven wheel via a transmission belt 606. The positioning frame 607 is mounted on the transmission belt 606. When the motor 603 is turned on, the motor 603 drives the drive wheel 604 to rotate, which in turn drives the driven wheel to rotate, thereby causing the symmetrical positioning frames 607 to move towards each other.
