Description

Technical Field

[0001] The present invention belongs to the technical field of magnets, and in particular relates to an assembly method and equipment for a Halbach magnetic assembly. Background Art

[0002] For a Haier shell magnetic component used in mobile phone cameras, such as Figure 1 As shown, the magnetic assembly 1 is composed of two magnets with vertical polarity and one magnet with horizontal polarity (the magnet with vertical polarity is hereinafter referred to as the large magnet 12, and the magnet with horizontal polarity is hereinafter referred to as the small magnet 11). The magnetic assembly 1 requires the small magnet 11 to be in the middle and the large magnet 12 to be combined on both sides. According to production needs, the magnetic assembly 1 and the iron piece 2 need to be assembled together. The shape of the iron piece 2 needs to match the magnetic assembly 1, such as Figure 2 As shown, the cross section of the iron piece 2 is L-shaped, including a horizontal plate 21 and a vertical plate 22 perpendicular to each other. The assembly steps are as follows: place the assembled magnetic assembly on the jig, use a glue dispenser to dispense glue on one side (hereinafter referred to as the front) and the top surface of the magnetic assembly, so that the front and top surfaces of the magnetic assembly are covered with glue, then place the iron piece, fit the vertical plate and horizontal plate of the iron piece to the front and top surfaces of the magnetic assembly after the glue is dispensed, and then squeeze the iron piece to press the iron piece and the magnetic assembly together. The structure after compression is as shown in FIG. Figure 3 As shown; finally, the jig is placed on a pallet, which is then placed in a tunnel oven for high-temperature curing, completing the entire assembly process. Due to the unique structure and small size of the magnetic component (length: 4.1-4.6mm, height: 0.6-1.0mm, width: 1.1-1.5mm), and the multiple steps involved, this series of assembly processes has not yet been replaced by mechanical equipment, resulting in low production efficiency and high labor costs.

[0009] The assembly method comprises the following steps:

[0010] S1. Place the assembled magnetic component flat on the jig, then place the jig into the feeding assembly, which will transfer the jig to the dispensing station on the flip platform.

[0011] S2. The flip drive device drives the flip platform to flip 40°-50° to tilt, so that the top surface and the front surface of the magnetic component on the dispensing station are tilted upward, and then the dispensing machine dispenses glue on the top surface and the front surface of the magnetic component. After dispensing glue, the flip platform flips back to its original position;

[0012] S3, the feeding component transports the glued fixture to the iron piece placement station. Then, the iron piece picking and placing mechanism grabs the iron piece on the iron piece loading tray and places the iron piece on the magnetic assembly of the iron piece placement station, so that the horizontal plate and vertical plate of the iron piece are respectively in contact with the top surface and front surface of the magnetic assembly;

[0013] S4. After the iron parts are placed, the feeding assembly transfers the fixture to the pressure holding station, and then the upper pressure holding push rod and the side pressure holding push rod are started at the same time to squeeze the top surface and the front surface of the magnetic assembly respectively to complete the pressure holding of the magnetic assembly.

[0015] Further, in step S1, a plurality of jig acupoints are provided on the top of the rear side wall of the jig, which are arranged side by side on the left and right, and the magnetic assembly is placed flat on the jig acupoints; in step S2, the gluing station passes through the flip platform on the left and right, and the front and rear sides of the gluing station are provided with front side walls and rear side walls. When the jig is located on the gluing station, the jig acupoints are higher than the rear side wall of the flip platform, so that the top surface and front side of the magnetic assembly are exposed; the first flipping mechanism also includes a first pivot seat and a second pivot seat arranged side by side in front and back, and the middle part of the flip platform is rotatably set on the second pivot seat, and the flip driving device is a telescopic rod, one end of the telescopic rod is rotatably set on the first pivot seat, and the other end is pivotally connected to the front of the flip platform, so that before gluing, one end of the telescopic rod is stretched and drives the front of the flip platform to flip downward, and the rear of the flip platform flips upward, thereby flipping the magnetic assembly to its top surface and front side tilted upward, and the flip angle of the flip platform is 45°.

[0016] Further, in step S2, the first flipping mechanism also includes a positioning plate, which is arranged on the rear side of the flipping platform for forward and backward movement, and a positioning opening is provided on the front side of the positioning plate, so that before the flipping platform flips, the positioning plate moves forward so that the jig on the dispensing station is stuck in the positioning opening to position the front and rear positions and left and right positions of the jig. After positioning, the positioning plate retreats, the flipping platform flips again, and then dispensing is performed.

[0018] Further, in step S2, the dispensing machine also includes a base, which is slid forward and backward and is arranged below the first track and the second track. The three-axis robotic arm is mounted on the base, and the first flipping mechanism is arranged on the base. The left and right sides of the flipping platform are provided with horizontally arranged rollers, and the edges of the rollers protrude from the left and right sides of the flipping platform. When the jig moves to the dispensing station, the base drives the first flipping mechanism to move backward, and the two rollers on the flipping platform separate the jigs on the left and right sides of the dispensing station, and then positions the jig and flips the flipping platform. Then the three-axis robotic arm drives the nozzle to dispense glue on the top and front surfaces of the magnetic component.

If qualified, the second flip mechanism is reset and enters the next step. If unqualified, the prompt mechanism prompts the staff to remove the unqualified jig.

[0020] Furthermore, the feeding assembly also includes a first conveying assembly and a second conveying assembly, and the first conveying assembly and the second conveying assembly are respectively located on one side of the iron placement assembly and the pressure holding assembly, and the first conveying assembly includes a dual-axis robotic arm and a clamping cylinder, and the dual-axis robotic arm is mounted on the conveyor belt, and the clamping cylinder is arranged on the dual-axis robotic arm and aligned with the iron placement station, so that in step S3, after the feeding assembly transports the jig to the conveyor belt, the dual-axis robotic arm drives the clamping cylinder to grab the jig on the conveyor belt to the iron placement station, and after the iron placement is completed, the first conveying assembly transports the jig back to the conveyor belt; the structure of the second conveying assembly is the same as that of the first conveying assembly, and the cylinder clamp of the second conveying assembly is aligned with the pressure holding station, then in step S4, the second conveying assembly transports the jig on the conveyor belt to the pressure holding station, and transports the jig after pressure holding back to the conveyor belt.

[0021] Furthermore, the assembly equipment further includes a pallet, which is located on one side of the conveyor belt. The feeding assembly further includes a third transport assembly, the structure of the third transport assembly is the same as that of the first transport assembly, and the dual-axis robotic arm of the third transport assembly is mounted above the conveyor belt and the pallet, so that the assembly method further includes the following steps:

[0022] S5. The third transport component transports the multiple jigs that have been pressurized on the conveyor belt to the pallet in sequence until the pallet is full. Then the worker sends the pallet full of jigs into the tunnel furnace for high-temperature curing.

[0023] The present invention also provides a Halbach magnetic assembly assembly device, including a feeding assembly, a glue dispensing assembly, an iron placing assembly, a pressure maintaining assembly and a jig;

[0024] The jig is used to load the magnetic component, and the glue dispensing component, the iron piece placing component and the pressure holding component are arranged above or on one side of the feeding component, and the feeding component transports the jig to the glue dispensing component, the iron piece placing component and the pressure holding component;

[0025] The dispensing assembly includes a dispensing machine and a first flipping mechanism, the first flipping mechanism includes a flipping platform and a flipping drive device, the flipping platform is provided with a dispensing station, the dispensing station is docked with the feeding assembly, the flipping drive device is connected to the flipping platform to drive the flipping platform to flip, so that the top surface and the front surface of the magnetic assembly on the flipping platform are tilted upward, and the dispensing machine is located above the dispensing station to dispense glue on the top surface and the front surface of the magnetic assembly;

The upper pressure-keeping push rod is located above the pressure-keeping station, and the side pressure-keeping push rod is located on one side of the pressure-keeping station.

[0028] After adopting the above solution, the beneficial effects of the present invention are:

[0029] 1. The present invention uses mechanical equipment to automatically complete the processes of dispensing, loading iron parts and maintaining pressure, thereby realizing the automation of magnetic component assembly, reducing labor costs and burdens, and improving production efficiency.

[0030] 2. Since the glue dispensing machine can only dispense glue vertically downward, before dispensing, the present invention flips the fixture through the first flipping mechanism, so that the top surface and the front surface of the magnetic component are flipped to face upward, so that the glue dispensing machine can dispense glue to the top surface and the front surface of the magnetic component successively or simultaneously. During this dispensing process, the first flipping mechanism does not need to be flipped again. The existing dispensing equipment requires that after dispensing glue on one side of the magnetic component, the dispensing machine moves up, and then a flipping device drives the magnetic component to flip to the other side facing up, and then dispensing glue, or after dispensing glue on one side, the dispensing machine is driven to flip an angle to dispense glue on the other side. The existing dispensing process cannot achieve continuous dispensing, and since the shapes and sizes of the two dispensing surfaces are different, the dispensing positions are also different, and the movement parameters of the dispensing machine need to be adjusted frequently. The present invention can continuously and uninterruptedly complete the dispensing of glue on the top and front surfaces of the magnetic component, and can also complete the dispensing of glue on the top and front surfaces of the magnetic component at the same time, which can improve the efficiency of the dispensing process, and the dispensing position is fixed after the top and front surfaces of the magnetic component are flipped to tilt upward, and there is no need to frequently adjust the position of the dispensing machine, and the dispensing operation is simpler and more convenient.

[0031] 3. The present invention uses the first flipping mechanism to tilt the top surface and the front surface of the magnetic component upward. By setting two rows of nozzles, glue can be dispensed on both sides of the magnetic component at the same time. Double-sided glue coating can be completed in a single operation, reducing the repeated positioning time by 50%, greatly improving production efficiency.

[0032] 4. The first flipping mechanism of the present invention is also provided with a positioning plate, which can position the front and back positions and left and right positions of the fixture on the dispensing station to ensure that the dispensing position is fixed each time, thereby improving the dispensing accuracy. In addition, the present application is also provided with a glue inspection component to check whether the dispensing is qualified, thereby improving the yield rate.

[0033] 5. The present invention adopts a multi-station parallel setting, that is, the glue dispensing component, the iron piece placing component and the pressure maintaining component operate in parallel, which further improves the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0055] like Figure 1-3 As shown, the present invention requires the structure to be Figure 1 The magnetic assembly 1 and the structure shown are as follows Figure 2 The iron parts 2 shown are assembled together, and the assembled structure is as follows Figure 3 As shown, the magnetic assembly 1 consists of a small magnet 11 and two large magnets 12. The assembled magnetic assembly 1 is not a regular rectangular parallelepiped structure, but a special-shaped structure with an obtuse angle between the two large magnets 12. The structure of the iron piece 2 matches the shape of the magnetic assembly 1. The horizontal plate 21 and the vertical plate 22 of the iron piece 2 need to be fitted with the top and front surfaces of the magnetic assembly 1 respectively, so glue needs to be applied on the top and front surfaces of the magnetic assembly 1. Figure 1 The shaded dots in the figure represent the glue points after dispensing. After dispensing, the iron component 2 is placed on the magnetic assembly 1. Then, pressure is maintained on the top and front surfaces of the magnetic assembly 1 to complete the assembly of the magnetic assembly 1 and the iron component 2. Due to the unique structure and small size of the magnetic assembly 1 (the length of the magnetic assembly 1 is only 4.1-4.6mm, the height is only 0.6-1.0mm, and the width is only 1.1-1.5mm), the traditional assembly process is still manual. To improve production efficiency and reduce labor costs, the present invention provides a Halbach magnetic assembly assembly method and equipment.

[0056] like Figure 4-17 As shown, the assembly equipment includes a machine 4, a jig 3 and a feeding component 5, a glue dispensing component 6, a glue inspection component 7, an iron piece placing component 8, and a pressure holding component 9 arranged on the machine 4, and a PLC controller (not shown in the figure) for controlling the operation of each component. The glue dispensing component 6, the glue inspection component 7, the iron piece placing component 8, and the pressure holding component 9 are located above or on one side of the feeding component 5. The jig 3 is provided with a number of jig points 31 for loading the magnetic component 1. The feeding component 5 is used to transport the jig 3 to the workstations of each component.

[0057] Key references Figure 6-7 The feeding assembly 5 includes a feeding cylinder 51, a first track 52, a second track 53, and a conveyor belt 54. The first track 52, the second track 53, and the conveyor belt 54 are arranged in a straight line from left to right, with the left end being the feed port and the right end being the discharge port. The feeding cylinder 51 is arranged at the feed port of the first track 52, specifically above the feed port of the first track 52. The piston rod of the feeding cylinder 51 is connected to a push plate 511. The bottom of the push plate 511 is located in the first track 52 to push the jig 3 to move. A sensor for sensing the jig 3 (not shown in the figure) is provided at the feed port of the first track 52. The sensor is connected to the feed cylinder 51 for signal transmission. The sensor can be a fiber optic sensor. After multiple jigs 3 are placed in the feeding port of the first track 52 in sequence, specifically on the right side of the push plate 511, the sensor receives a signal to prompt the feeding cylinder 51, and the piston rod of the feeding cylinder 51 begins to extend and retract to push the jigs 3 placed in sequence to the right, so that the multiple jigs 3 move side by side to the right, that is, the latter jig 3 will push the previous jig 3 to move, and when the jig 3 moves to the conveyor belt 54, the conveyor belt 54 transports the jig 3.

[0058] Key references Figure 7-12The dispensing component 6 includes a dispensing machine 61 and a first flipping mechanism 62. The dispensing machine 61 includes a three-axis robotic arm 611, a base 612 and a nozzle 613 for dispensing. The base 612 is set on the machine table 4 for sliding back and forth, and is located below the first track 52 and the second track 53. The three-axis robotic arm 611 is mounted on the base 612, and the nozzle 613 is set on the three-axis robotic arm 611. The three-axis robotic arm 611 drives the nozzle 613 to move up and down, left and right, and forward and backward to dispense glue to the magnetic component 1.

[0059] The first flipping mechanism 62 is provided on the base 612 and is located between the first track 52 and the second track 53. The first flipping mechanism 62 includes a flipping platform 621 and a flipping drive device 622. A glue dispensing station 63 is provided on the flipping platform 621, and the glue dispensing station 63 is docked with the feeding assembly 5. Specifically, the glue dispensing station 63 passes through the flipping platform 621 from left to right, and the left and right ends of the glue dispensing station 63 are docked with the discharge port of the first track 52 and the feed port of the second track 53, respectively, so that the feeding cylinder 51 can push the fixture 3 onto the glue dispensing station 63. The flipping drive device 622 is connected to the flipping platform 621 to drive the flipping platform 621 to flip, so that the top surface and the front surface of the magnetic assembly 1 on the flipping platform 621 are tilted upward, as shown in FIG. Figure 12 As shown, the nozzle 613 dispenses glue vertically downward. After the magnetoresistive element is turned over to the top surface and the front surface facing upward, the nozzle 613 can dispense glue on both surfaces. The direction of dispensing glue is as follows: Figure 12 As shown by the arrows in FIG, the nozzle 613 can complete the dispensing of glue on both surfaces by moving up and down and horizontally.

[0060] Specifically, the number of the nozzles 613 can be one or more. If there is one nozzle, the nozzle 613 dispenses glue to the top and front surfaces of the magnetic component 1 in sequence. If there are multiple nozzles 613, the multiple nozzles 613 can be arranged in two rows to Figure 7 For reference, the fixture 3 is placed so that the front of the magnetic component 1 faces backward, and the multiple nozzles 613 can be arranged in two parallel rows. The two rows of nozzles 613 correspond to the glue dispensing positions on the top and front of the flipped magnetic component 1 respectively. Driven by the three-axis robotic arm 611, the two rows of nozzles 613 can dispense glue to the top and front of the magnetic component 1 at the same time. The number of nozzles 613 in each row can be one or more, and the number of nozzles 613 preferably corresponds to the required glue points, for example Figure 1As shown, seven locations on each surface of the magnetic component 1 require glue application, so each row of nozzles 613 has seven nozzles. The three-axis robotic arm 611 drives two rows of nozzles 613 to the locations corresponding to the glue application locations, and then drives the nozzles 613 downward to complete glue application on both surfaces of the magnetic component 1. This allows for double-sided glue application in a single operation, significantly improving production efficiency. Furthermore, multiple nozzles 613 can be arranged in a row, with each row of nozzles 613 capable of applying glue to one surface at a time.

[0061] If the existing technology is used to dispense glue on the magnetic component 1, there are generally two ways. One is to first keep the magnetic component 1 horizontal, and the glue dispenser dispenses glue vertically downward on the top surface of the magnetic component 1, and then the glue dispenser nozzle moves up, and the magnetic component 1 is flipped 90° by a flipping device before dispensing glue on the other side; the other is to keep the magnetic component 1 still, and after the glue dispenser dispenses glue on one side, the glue dispenser nozzle changes the angle to dispense glue on the other side. In these two methods, the glue dispenser cannot complete the glue dispensing continuously. After dispensing glue on one side, the fixture 3 or the nozzle needs to be flipped, and the glue dispensing efficiency is low. Moreover, since the shapes and sizes of the two glue dispensing surfaces are different, the glue dispensing positions are also different. After dispensing glue on one side, the movement parameters of the glue dispenser need to be adjusted, and the adjustment is frequent, the operation is complicated and time-consuming. However, the present invention can continuously and uninterruptedly or simultaneously complete the glue dispensing on both sides of the magnetic component 1, and the glue dispensing efficiency is high. Moreover, after the magnetic component 1 is flipped, the glue dispensing position is fixed, and there is no need to frequently adjust the position of the glue dispenser nozzle, and the glue dispensing operation is simpler and more convenient.

[0062] It should be noted that after many adjustments, the flipping angle of the flipping platform 621 is 40°-50°. If it exceeds this angle range, the glue dispensing position will be offset and the glue spraying will be uneven. The flipping angle of 45° is the best. At the flipping position of 45°, the inclination angles of the top and front surfaces of the magnetic component 1 are consistent, which can ensure the consistency of the glue dispensing thickness and uniformity on the two surfaces, thereby improving the glue dispensing accuracy.

[0063] Furthermore, a plurality of jig acupoints 31 are provided on the top of the rear side wall of the jig 3 and arranged side by side on the left and right. The magnetic component 1 is placed flat on the jig acupoints 31, and the top and front surfaces of the magnetic component 1 are exposed. The front and rear sides of the dispensing station 63 are provided with a front side wall 6211 and a rear side wall 6212. When the jig 3 is located on the dispensing station 63, the jig acupoints 31 are higher than the rear side wall 6212 of the flipping platform 621, so that the top and front surfaces of the flipped magnetic component 1 are also exposed, and dispensing can be performed. After dispensing one magnetic component 1, the dispensing machine 61 moves to the top of the next magnetic component 1 for dispensing. After the magnetic components 1 on all the jig acupoints 31 are glued, the flipping platform 621 is reset for the next round of dispensing.

[0064] The first flip mechanism 62 also includes a first pivot seat 623, a second pivot seat 624, a bottom plate 625 and a positioning plate 626. The bottom plate 625 is arranged on the base 612. The first pivot seat 623 and the second pivot seat 624 are arranged side by side on the bottom plate 625. The middle part of the bottom surface of the flip platform 621 is rotated and arranged on the second pivot seat 624. The flip driving device 622 is a telescopic rod, which can be a hydraulic push rod or a cylinder push rod. One end of the telescopic rod is rotated and arranged on the first pivot seat 6 23, and the other end is pivotally connected to the front of the flip platform 621. The middle part of the flip platform 621 is rotatably set on the second pivot seat 624. The flip driving device 622 is a telescopic rod, one end of the telescopic rod is rotatably set on the first pivot seat 623, and the other end is connected to the front side of the flip platform 621. Therefore, before dispensing, one end of the telescopic rod is stretched and drives the front of the flip platform 621 to flip downward, and the rear part of the flip platform 621 will flip upward, thereby flipping the magnetic component 1 to its top surface and front side tilted upward.

[0065] Preferably, an L-shaped connecting rod 627 is further provided between the telescopic rod and the flip platform 621. The horizontal rod of the L-shaped connecting rod 627 is fixed to the bottom surface of the flip platform 621, and the vertical rod of the L-shaped connecting rod 627 is arranged downward, and the bottom end of the vertical rod is pivotally connected to the other end of the telescopic rod. The angle between the horizontal rod and the vertical rod of the L-shaped connecting rod 627 is slightly less than 90 degrees, so that the vertical rod of the L-shaped connecting rod 627 tilts backward, thereby stretching the telescopic rod to push the front side of the flip platform 621 downward. In addition to the telescopic rod, the flip drive mechanism can also be a motor. The motor shaft can be directly or indirectly connected to the flip platform 621 to drive the flip platform 621 to rotate.

[0066] The positioning plate 626 is arranged on the rear side of the flipping platform 621, and the positioning plate 626 is arranged horizontally. A cylinder is fixed on the bottom of the positioning plate 626 to push the positioning plate 626 to move forward and backward. A C-shaped positioning opening 6261 is provided on the front side of the positioning plate 626. The length of the jig 3 is greater than the length of the dispensing station 63. Before the flipping platform 621 flips, the positioning plate 626 moves forward so that the jig 3 on the dispensing station 63 is stuck in the positioning opening 6261. The left and right end surfaces of the positioning opening 6261 can position the left and right positions of the jig 3. A positioning protrusion 6262 is also provided in the positioning opening 6261. The positioning protrusion 6262 abuts against the rear side of the jig 3 to position the front and rear positions of the jig 3. The positioning of the positioning plate 626 ensures that the dispensing position is fixed each time, thereby improving the dispensing accuracy.

[0067] As a preferred embodiment, a first limiting plate 628 and a second limiting plate 629 are provided below the flipping platform 621. The top of the first limiting plate 628 is provided with an inclined slope, and is located below the front of the flipping platform 621. After the flipping platform 621 is flipped, its bottom surface abuts against the inclined surface of the first limiting plate 628, thereby preventing the flipping platform 621 from continuing to flip, so as to position the flipping platform 621 in an inclined position of about 45°. The top of the second limiting plate 629 is a plane, and is located below the rear of the flipping platform 621, and can abut against the rear of the flipping platform 621 to limit the flipping platform 621 to a horizontal position.

[0068] Furthermore, horizontally arranged rollers 6213 are provided on the left and right sides of the flipping platform 621, and the edges of the rollers 6213 protrude from the left and right sides of the flipping platform 621. The rollers 6213 can be specifically arranged on the front side wall 6211 of the dispensing station 63. When the jig 3 moves to the dispensing station 63, the base 612 drives the first flipping mechanism 62 to move backward. During the movement, the two rollers 6213 on the flipping platform 621 can separate the jigs 3 on the left and right sides of the dispensing station 63 to avoid the jigs 3 on the left and right sides from being stuck and adhered to the jig 3 on the dispensing station 63, which affects the rotation of the flipping platform 621. After the base 612 drives the first flipping mechanism 62 to move backward, positioning and flipping operations are performed.

The camera 71 is preferably a CCD camera 71, which is located above the glue inspection station 74. The prompting mechanism 73 is signal-connected to the camera 71, that is, both are signal-connected to the PLC controller. After the dispensing is completed and the flip platform 621 rotates and resets, the feeding component 5 transports the jig 3 to the glue inspection station 74, and then the second flip mechanism 72 performs the same action as the first flip mechanism 62, so that the top surface and the front surface of the magnetic component 1 on the glue inspection station 74 are tilted upward, and the camera 71 takes a picture of the magnetic component 1 to determine whether the dispensing of the magnetic component 1 is qualified. If qualified, the second flip mechanism 72 is reset and enters the next step. If unqualified, the prompt mechanism 73 prompts the staff to remove the unqualified jig 3. The prompt mechanism 73 can be an intelligent display screen. The camera 71 can send the photo results to the intelligent display screen, and the manual judgment of whether the dispensing is qualified can also be made by the PLC controller. If unqualified, the intelligent display screen can issue a voice prompt, or it can display pictures and text on the screen to prompt.

After the iron piece 2 is placed, the first conveying component 55 transports the jig 3 back to the conveyor belt 54.

[0073] As a preferred embodiment, the conveyor belt 54 is provided with a blocking cylinder 555. When the jig 3 moves to the bottom of the clamping cylinder 552, the blocking cylinder 555 is pushed out to block the jig 3, stopping the jig 3 from moving, allowing the clamping cylinder 552 to clamp the jig 3. After the blocking cylinder 555 is extended, the conveyor belt 54 pauses. After the jig 3 with the iron piece 2 placed on it is moved back onto the conveyor belt 54, the blocking cylinder 555 is reset and the conveyor belt 54 continues to convey.
