Description

Technical Field

[0001] The utility model relates to the technical field of gluing, in particular to a rotary clamp and gluing equipment. Background Art

[0002] Some metal or plastic products require coating or dotting with glue during processing for connection, aesthetics, or protection. Operators often use manual glue guns to apply glue to products. Manual glue application cannot accurately and consistently control the amount of glue applied, resulting in uneven glue thickness and affecting product quality.

[0003] To this end, relevant research and technical personnel have designed a gluing device, but most of the designed gluing devices can only apply glue to one side of the workpiece. After the gluing is completed on this side, it needs to be manually flipped over before the other side can be applied. During the gluing process, the gluing device cannot automatically flip the workpiece, so it is necessary to set up a dedicated post, which increases the labor cost and the workload of the workers.

DETAILED DESCRIPTION

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0046] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0048] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0049] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0050] The terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0051] Unless otherwise expressly specified or limited, terms such as "disposed" and "connected" should be interpreted broadly. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0053] Existing gluing devices replace manual gluing, avoiding the problem of being unable to accurately control the amount of glue applied during the gluing process and reducing the probability of uneven glue thickness. However, most existing gluing devices can only apply glue to one side of the workpiece. After gluing is completed on that side, the workpiece must be manually flipped before continuing to apply glue to the other side. The gluing device cannot automatically flip the workpiece during the gluing process.

[0054] The rotary fixture and gluing device provided in the embodiments of the present invention can solve the above-mentioned problems. The rotary fixture is used in the gluing device to automatically flip the workpiece during gluing. Of course, the rotary fixture is not limited to the gluing device and can also be used as an auxiliary fixture in other machining processes such as turning, cutting, and planing.

[0055] The rotary fixture and the gluing device of the present invention will be described in detail below.

[0056] Please refer to Figure 1 and Figure 2 The gluing device includes an upper outer frame 1, a lower outer frame 2, a mounting platform 3, a gluing device 4, a three-axis displacement device 5, a rotating fixture 6, a gluing assembly 7, and a controller. The upper outer frame 1 and the lower outer frame 2 are connected to form an integral unit. The upper outer frame 1 and the lower outer frame 2 enclose an interior to form a closed space. The mounting platform 3, the gluing device 4, the three-axis displacement device 5, the rotating fixture 6, and the gluing assembly 7 are all arranged within this closed space to form an integrated device. At the same time, the upper outer frame 1 and the lower outer frame 2 also serve to protect the gluing device 4, the three-axis displacement device 5, the rotating fixture 6, and the gluing assembly 7 within the closed space. The three-axis displacement device 5 is used to drive the gluing device 4 to move and apply glue to different parts of the workpiece 8. The gluing device 4 is used to apply glue to the workpiece 8. The rotating fixture 6 is used to clamp and fix the workpiece 8 and drive the workpiece 8 to flip. The controller is used to control the movement direction and movement speed of the three-axis displacement device 5 and the rotation speed of the rotating fixture 6.

[0057] The upper outer frame 1 includes an upper frame beam 10 , a top plate 11 and an upper side plate 12 . The top plate 11 is disposed on the top of the upper frame beam 10 , and the upper side plate 12 is disposed in the circumferential direction of the upper frame beam 10 .

[0058] Specifically, the upper frame beam 10 is constructed by four vertically arranged vertical beams and eight horizontally arranged cross beams. The four vertical beams are of equal length and arranged parallel to each other. The cross beams are sequentially connected at both ends of two adjacent vertical beams, thereby forming a regular quadrangular prism frame structure. The connection between the vertical beams and the cross beams can be made in a variety of forms such as welding, screw / bolt connection, mortise and tenon connection, etc. The vertical beams and the cross beams can be made into tubular shapes such as square tubes and round tubes, or other shapes, which are not limited here. The vertical beams and the cross beams can be made of metals such as iron and aluminum alloys, or can be cast and formed by plastics in combination with molds, or can be made of semi-finished materials such as angle steel and I-beams. The materials of the vertical beams and the cross beams can be selected according to actual conditions.

[0059] The top plate 11 and upper side plates 12 are both rectangular plates. They are connected to the upper frame beam 10 by adhesive bonding, screws, or snap-fit connections. If snap-fit connections are used, the upper frame beam 10 is provided with a slot into which the top plate 11 is inserted. The upper side plates 12 are connected to the upper frame beam 10 by screws or bolts, providing a more secure connection. The top plate 11 and upper side plates 12 can be made of a plastic such as PVC, which offers the advantage of being lightweight.

[0060] The lower outer frame 2 includes a lower frame beam 20 , a bottom plate 21 and a lower side plate 22 . The bottom plate 21 is connected to the lower end of the lower frame beam 20 , and the lower side plate 22 is provided in the circumferential direction of the lower frame beam 20 .

[0061] The lower frame beam 20 is similarly constructed from four vertical beams and four horizontal beams. The four vertical beams are of equal length and arranged parallel to each other. The upper ends of the four vertical beams connect to the vertical beams of the upper frame beam 10, and the four horizontal beams connect to the lower ends of the four vertical beams. The bottom plate 21 and the lower side plate 22 are both rectangular plates. The bottom plate 21 is welded to the vertical beams, while the lower side plate 22 is connected to the vertical beams using screws, bolts, or hinges.

[0062] Four adjustable support seats 23 are provided at the lower end of the lower frame beam 20. The adjustable support seats 23 can keep the gluing equipment at a certain height from the ground to prevent the gluing equipment from getting damp. The four adjustable support seats 23 can work together to place the gluing equipment stably on uneven ground. The adjustable support seat 23 is a common threaded height adjustment support on the market. Of course, the adjustable support seat 23 can also be a hydraulic telescopic cylinder, which controls the extension and contraction of the hydraulic telescopic cylinder by injecting or extracting hydraulic fluid, thereby completing the adjustment of the height of the gluing equipment.

[0063] In order to facilitate the movement of the gluing equipment, four universal wheels 24 are installed on the crossbeam of the lower frame beam 20. The four universal wheels 24 are respectively located near the four adjustable support seats 23, so as to realize the convenient movement of the gluing equipment.

[0064] Continue to refer Figure 1 and Figure 2The mounting platform plate 3 is a rectangular flat plate. The mounting platform plate 3 is arranged between the upper frame beam 10 and the lower frame beam 20. It is used to provide an installation position for the gluing device 4, the three-axis displacement device 5 and the rotating fixture 6, and needs to withstand a large pressure. Therefore, the mounting platform plate 3 is welded to the upper frame beam 10 and the lower frame beam 20. At the same time, the mounting platform plate 3 is made of a high-strength, low-deformation plate, such as aluminum alloy, which is conducive to ensuring stability and reliability during gluing.

[0065] refer to Figure 3 and Figure 4 The top of the mounting platform 3 is provided with a three-axis displacement device 5, a gluing device 4, and a rotating fixture 6. The three-axis displacement device 5 includes an X-axis displacement structure 50, a Z-axis displacement structure 53, and a Y-axis displacement structure 55. The Z-axis displacement structure 53 is slidably mounted on the X-axis displacement structure 50. The gluing device 4 is mounted on the Z-axis displacement structure 53, driving the gluing device 4 to move. The rotating fixture 6 is mounted on the Y-axis displacement structure 55, driving the rotating fixture 6 to move, thereby applying glue to different parts of the workpiece 8.

[0066] refer to Figure 5 The X-axis displacement structure 50 includes two columns 501, an X-axis mounting plate 502, an X-axis sliding cover 503, an X-axis slider 504, and an X-axis driver 505. The columns 501 are connected at their bases to the mounting platform 3. The X-axis mounting plate 502 is mounted on top of the two columns 501. The X-axis sliding cover 503 is mounted on the upper surface of the X-axis mounting plate 502. The X-axis sliding cover 503 has a first chute along its longitudinal axis. The X-axis slider 504 is slidably mounted on the first chute. The X-axis slider 504 is connected to the driving end of the X-axis driver 505.

[0067] Optionally, the X-axis slider 504 is connected to the driving end of the X-axis driving component 505 through a force transmission rod, and the X-axis driving component 505 is a push rod motor; the push rod of the push rod motor is connected to one end of the force transmission rod through an axis connector, and the other end of the force transmission rod is welded to the X-axis slider 504.

[0068] As another embodiment, the X-axis driving component 505 is a servo motor, which is connected to a screw rod through a shaft connector. The other end of the screw rod away from the servo motor rotates with the X-direction slide cover 503 through a bearing; a threaded hole along the X-axis direction is opened on the X-direction slider 504, and the screw rod passes through the threaded hole on the X-direction slider 504 and can rotate. When the servo motor is working, it drives the screw rod to rotate. Since the screw rod only rotates and does not move, it drives the X-direction slider 504 to slide on the first slide groove of the X-direction slide cover 503.

[0069] In addition, in order to accurately measure and control the moving distance of the X-axis slider 504, an X-axis position sensor 506 for detecting the position of the X-axis slider 504 is also provided on the X-axis slide cover 503. The X-axis position sensor 506 communicates with the controller and is used to transmit the measured X-axis slider 504 position information to the controller in real time.

[0070] refer to Figure 6 and Figure 7 The Z-axis displacement structure 53 is connected to the X-axis slider 504 through the XZ connecting plate 54.

[0071] The Z-axis displacement structure 53 includes a Z-fixing plate 531, a Z-sliding cover 532, a Z-sliding block 533, and a Z-axis driver 534. The long side of the Z-fixing plate 531 is axially aligned in the vertical direction. The Z-sliding cover 532 is connected to a side surface of the Z-fixing plate 531. The Z-sliding cover 532 has a second chute along its long axis. The Z-sliding block 533 is slidably mounted on the second chute. The Z-sliding block 533 is connected to the driving end of the Z-axis driver 534.

[0072] The connection between the Z-axis slider 533 and the Z-axis driver 534 is similar to that between the X-axis slider 504 and the X-axis driver 505. The Z-axis driver 534 can also utilize a push rod motor or a servo motor. For details on the connection and drive method, refer to the above-mentioned sections regarding the X-axis slider 504 and the X-axis driver 505. The difference between the X-axis slider 504 and the X-axis driver 505 and the Z-axis slider 533 and the Z-axis driver 534 is that the Z-axis driver 534 drives the Z-axis slider 533 in the Z-axis direction.

[0073] Similarly, in order to accurately measure and control the moving distance of the Z-direction slider 533, a Z-direction position sensor 535 for detecting the position of the Z-direction slider 533 is also provided on the Z-direction slide cover 532. The Z-direction position sensor 535 communicates with the controller and is used to transmit the measured Z-direction slider 533 position information to the controller in real time.

[0074] In order to increase the reliability of the connection between the Z-axis displacement structure 53 and the X-axis displacement structure 50 , an XZ reinforcing connector 541 is connected between the XZ connecting plate 54 and the Z-direction fixing plate 531 to strengthen the connection.

[0075] refer to Figure 8 and Figure 9 The Y-axis displacement structure 55 includes a Y-axis sliding cover 551 , a Y-axis slider 552 , a Y-axis driving member 553 and a Y-axis position sensor 554 .

[0076] Among them, the Y-direction sliding cover 551 is perpendicular to the long axis direction of the X-direction sliding cover 503 and the long axis direction of the Z-direction sliding cover 532. A third sliding groove is opened on the Y-direction sliding cover 551 along its own long axis direction. The Y-direction slider 552 is slidably set on the third sliding groove, and the Y-direction slider 552 is driven to slide by the Y-axis driving member 553.

[0077] The connection between the Y-axis slider 552 and the Y-axis driver 553 is similar to that between the X-axis slider 504 and the X-axis driver 505. The Y-axis driver 553 can also utilize a push rod motor or a servo motor. For details on the connection and drive method, refer to the above-mentioned sections regarding the X-axis slider 504 and the X-axis driver 505. The difference between the Y-axis driver 553 and the X-axis driver 505 is that the Y-axis driver 553 drives the Y-axis slider 552 in the Y-axis direction.

[0078] Correspondingly, a Y-direction position sensor 554 is provided on the Y-direction slide cover 551, and the Y-direction position sensor 554 is used to detect the position of the Y-direction slider 552 on the Y-direction slide cover 551 in real time; the Y-direction position sensor 554 communicates with the controller and is used to transmit the measured Y-direction slider 552 position information to the controller in real time.

[0079] refer to Figure 10 In order to increase the gluing capacity of the gluing equipment, a single-sided gluing support structure 57 is further provided on the mounting platform plate 3 . The single-sided gluing support structure 57 is used to place the workpiece 8 and perform single-sided gluing on the workpiece 8 .

[0080] The single-sided glue coating support structure 57 includes a second sliding plate 571, connecting rods 572, and a workpiece mounting plate 573. There are multiple connecting rods 572, each connected at its ends to the second sliding plate 571 and the workpiece mounting plate 573. The workpiece mounting plate 573 is located above the second sliding plate 571. The workpiece 8 to be glued on one side is placed on the surface of the workpiece mounting plate 573, and glue is applied to the workpiece 8 via the glue coating device 4. The second sliding plate 571 is connected to another separately provided Y-axis slider 552, which is slidably mounted on a matching Y-axis slide cover 551. Since this portion is identical to the Y-axis displacement structure 55 described above, it will not be described in detail here.

[0081] It should be noted that, in this embodiment, the X-direction sliding cover 503 and the X-direction slider 504 , the Y-direction sliding cover 551 and the Y-direction slider 552 , and the Z-direction sliding cover 532 and the Z-direction slider 533 may cooperate in the same manner, including shape and driving method.

[0082] In order to protect the communication cables and wires in the gluing equipment, an X-direction drag chain plate 508 is provided on the side of the X-direction mounting plate 502, and an X-direction drag chain 507 is arranged on the X-direction drag chain plate 508. At the same time, a Y-direction drag chain plate 556 and a Y-direction drag chain 555 are arranged on the mounting platform plate 3. The communication cables and wires are arranged through the X-direction drag chain 507 and the Y-direction drag chain 555, thereby protecting the communication cables and wires.

[0083] The gluing device 4 is the most important actuator in the gluing equipment, and plays the role of mixing glue, discharging glue and applying glue. The gluing device 4 is described in detail below.

[0084] refer to Figures 11 to 14 The glue coating device 4 includes a Z-axis slide 40, a dual-liquid screw valve 41, a mixing glue cylinder 42, and a glue outlet pipe 43. The Z-axis slide 40 provides a mounting location for the dual-liquid screw valve 41 and is connected to the Z-axis displacement structure 53. The dual-liquid screw valve 41 is used to mix multiple single glue solutions to form a mixed and suitable glue.

[0085] One side surface of the Z-axis slide 40 is used to install the dual-liquid screw valve 41 , and the other side surface is fixedly connected to the Z-direction slider 533 , thereby moving together with the Z-direction slider 533 .

[0086] The dual-liquid screw valve 41 is fixed to a first mounting base 44, which is connected to the Z-axis slide 40. The dual-liquid screw valve 41 includes a liquid A stator 411 and a liquid B stator 414. The liquid A stator 411 is threadedly connected to a liquid A screw 412, while the liquid B stator 414 is threadedly connected to a liquid B screw 415. The liquid A stator 411 and the liquid A screw 412 form a sealed chamber. Liquid A screw 412 propels a single liquid of glue forward within the sealed chamber. The greater the angle of rotation of the liquid A screw 412, the greater the amount of liquid A glue discharged. Similarly, the liquid B stator 414 and the liquid B screw 415 also form another independent sealed chamber, with the liquid B screw 415 controlling the amount of liquid B glue discharged.

[0087] The A-liquid stator 411 is provided with an A-liquid inlet connector 413, through which the A-liquid glue is injected into the sealed chamber within the A-liquid stator 411. The B-liquid stator 414 is provided with a B-liquid inlet connector 416, through which the B-liquid glue is injected into the sealed chamber within the B-liquid stator 414.

[0088] The glue outlet ends of the liquid A stator 411 and the liquid B stator 414 are connected to the mixing glue cylinder 42. The discharged glue liquid A and glue liquid B are mixed evenly in the mixing glue cylinder 42 for use. The mixing glue cylinder 42 is connected to the glue outlet pipe 43 for discharging the mixed glue.

[0089] In this embodiment, the liquid A screw 412 and the liquid B screw 415 are each connected to two independently mounted servo motors. These independently mounted servo motors drive the screws, controlling the output of the two servo motors, respectively, to precisely control the glue ratio. Both servo motors are in communication with a controller, which controls their operating speeds. It should be noted that the dual-liquid screw valve 41 of this embodiment is conventional technology, and its specific operating principle and diagrams are not shown here.

[0090] Liquid A stator 411 and Liquid B stator 414 are connected to a glue storage container 48 via two separate glue delivery pipes. Glue storage container 48 stores a large amount of both Liquid A and Liquid B, enabling continuous glue application by the glue coating equipment. The chamber storing Liquid A in glue storage container 48 is connected to Liquid A inlet connector 413 via the Liquid A delivery pipe. The chamber storing Liquid B in glue storage container 48 is connected to Liquid B inlet connector 416 via the Liquid B delivery pipe (not shown). In this embodiment, glue storage container 48 is mounted on the exterior of upper outer frame 1.

[0091] Since glue A and glue B generate heat when mixed, the mixed glue has a high temperature, so the temperature of the mixed glue needs to be controlled.

[0092] refer to Figure 15 Combined with Figure 11 A refrigeration structure 46 is provided outside the glue outlet pipe 43 , and the glue in the glue outlet pipe 43 is cooled by the refrigeration structure 46 .

[0093] Refrigeration structure 46 includes a cooling plate 461 and cooling fins. Cooling plate 461 has a cooling channel 462, through which the rubber outlet pipe 43 passes. The cooling fins are in thermal contact with cooling plate 461. Heat from the rubber outlet pipe 43 is transferred to cooling plate 461, which in turn transfers the heat to the cooling fins, which in turn cool the device. The cooling fins in this embodiment are commercially available electric cooling fins.

[0094] In order to facilitate improving the cooling efficiency of the glue in the glue outlet pipe 43, a water cooling plate is also provided inside the refrigeration plate 461. The water cooling plate is provided with a water inlet and a water outlet. A water cooling channel is provided inside the water cooling plate. The water cooling channel is connected with the water inlet and the water outlet at the same time. The water inlet and the water outlet are respectively connected to the external cold water source through two different hoses, thereby further improving the cooling effect.

[0095] A U-shaped clip 463 is connected to the side of the cooling plate 461 . The U-shaped clip 463 is clamped on the second mounting seat 45 . The second mounting seat 45 is connected to the Z-axis slide 40 , thereby achieving positioning and fixation.

[0096] refer to Figure 16 Combined with Figure 11To apply glue discharged from the glue outlet pipe 43 with a certain pressure, a pressurizing structure 47 is provided at the outlet of the glue outlet pipe 43. A Y-shaped needle valve 475 is connected to the glue outlet pipe 43. The Y-shaped needle valve 475 has a three-way pipe structure. The first end of the Y-shaped needle valve 475 is connected to the glue outlet pipe 43, the second end of the Y-shaped needle valve 475 is connected to the glue outlet needle 476, and the third end of the Y-shaped needle valve 475 is connected to the pressurizing structure 47.

[0097] Specifically, the pressurizing structure 47 includes a pressurizing drive 471, a needle fixing block 472, a Y-type needle connector 473, and a locking member 474. The pressurizing drive 471 is used to pressurize the glue in the Y-type needle valve 475. The output end of the pressurizing drive 471 is connected through the Y-type needle connector 473 to transmit pressure. The pressurizing drive 471 is mounted on the needle fixing block 472, which is a Z-shaped block. In this embodiment, the pressurizing drive 471 is an SDA12 thin cylinder. The pressurizing drive 471 is threadedly connected to the needle fixing block 472 by bolts. The pressurizing drive 471 is connected to the upper part of the needle fixing block 472, so that the pressure output direction of the pressurizing drive 471 is vertical.

[0098] The needle fixing block 472 provides an installation position for the pressurized drive 471, the Y-type needle connector 473, and the Y-type needle valve 475, while limiting the Y-type needle connector 473 to move in only one direction, thereby limiting the direction in which the pressurized drive 471 applies pressure.

[0099] In addition, a locking piece 474 is provided on the side of the Y-type needle connector 473, and one end of the locking piece 474 can be used to squeeze the Y-type needle valve 475. A pressure-applying piston rod is provided on the upper part of the Y-type needle valve 475, and one end of the locking piece 474 is connected to the side wall of the piston rod, so that the position of the piston rod can be controlled, and the pressure value of the glue can be adjusted.

[0100] refer to Figure 17 Combined with Figure 8 The rotating fixture 6 is set on the Y-axis displacement structure 55. The rotating fixture 6 is fixed on the Y-direction slider 552 through the first sliding plate 60 and moves synchronously with the Y-direction slider 552.

[0101] The rotary fixture 6 includes a support block 61 , a rotary end block 62 , a workpiece mounting rotary plate 63 , a plurality of movable clamps 64 and a rotary driving member 65 .

[0102] In the first embodiment, the two support blocks 61 are both connected to the first sliding plate 60, which is connected to the Y-axis slider 552. The two support blocks 61 are spaced apart, and both support blocks 61 are rotatably engaged with a rotating end block 62. One end of the rotating end block 62 is a shaft, and the other end is a long strip. The shaft passes through the two side surfaces of the support block 61 and rotatably engages with the support block 61. The long strip is adhesively fixedly connected to the end wall of the workpiece mounting rotating plate 63; the rotating drive member 65 is a motor, and the rotating drive member 65 is arranged on the outside of one of the support blocks 61. The shaft of the rotating end block 62 there is connected to the output shaft of the motor via a coupling, and the motor drives the rotating end block 62 there to rotate, thereby driving the workpiece mounting rotating plate 63 to rotate.

[0103] In the second embodiment, there is one support block 61 and one rotating end block 62. Rotating end block 62 also has a shaft at one end and a long strip at the other. The shaft passes through both sides of support block 61 and rotates with support block 61. The strip is fixedly connected to the end wall of workpiece mounting rotating plate 63 by screws. A rotary drive member 65 is disposed outside support block 61 and is a motor. The shaft of rotating end block 62 is connected to the output shaft of the motor via a coupling, thereby rotating workpiece mounting rotating plate 63. Unlike the first embodiment, the rotary fixture of the second embodiment has a lower load-bearing capacity and is suitable for applying glue to smaller and lighter workpieces 8.

[0104] The workpiece mounting rotating plate 63 is used to place the workpiece 8. In order to prevent the workpiece 8 from moving during the gluing process, a plurality of movable clamps 64 are provided on the workpiece mounting rotating plate 63 to clamp and fix the workpiece 8. The movable clamps 64 can be torsion spring clamps available on the market.

[0105] Furthermore, the workpiece mounting rotating plate 63 is provided with a placement cavity, which does not penetrate the workpiece mounting rotating plate 63, but only forms a concave cavity in the workpiece mounting rotating plate 63. The workpiece 8 is placed in the placement cavity, which further avoids the relative displacement of the workpiece 8 and the workpiece mounting rotating plate 63 during the flipping process. The movable clamp 64 is located at the edge of the placement cavity, exerting pressure on the workpiece 8, and pressing the workpiece 8 into the placement cavity of the workpiece mounting rotating plate 63.

[0106] A gluing channel is provided on the workpiece mounting rotating plate 63. When the gluing is completed on the exposed side of the workpiece 8, the workpiece mounting rotating plate 63 drives the workpiece 8 to flip over so that the other side flips upward, and the glue needle 476 passes through the gluing channel to apply glue to the un-glued surface of the workpiece 8.

[0107] The gluing channel on the workpiece mounting rotating plate 63 may be provided in various forms, such as holes, slits, grooves, etc., and its specific form is determined by the area of gluing and the gluing path of the workpiece 8. If the workpiece 8 needs to be coated with a wavy line glue layer, the gluing channel may be provided as a wavy line strip slit.

[0108] Before gluing the workpiece 8, the gluing device 4 needs to exhaust the air in the glue outlet pipe 43 so that the glue can reach the glue outlet needle 476 before formal gluing; after gluing the workpiece 8, residual glue remains in the glue outlet needle 476; in order to prevent glue from dripping onto the mounting platform plate 3 before and after gluing, a glue connecting component 7 is provided on the mounting platform plate 3, and the glue connecting component 7 is used to receive the glue discharged by the gluing device 4 before and after gluing.

[0109] Reference again Figure 4 The glue connecting component 7 includes a glue connecting container 70 and a bracket 71. The glue connecting container 70 is installed on the bracket 71. The bottom end of the bracket 71 is connected to the mounting platform plate 3. The upper end of the glue connecting container 70 is open for receiving glue dripping from the glue discharge needle 476.

[0110] In order to prevent people from accidentally opening the equipment or inserting body parts into the equipment when the gluing equipment is working, a grating 14 is set at the switch door of the equipment, and a buzzer 15 is set on the upper outer frame 1 of the equipment. The grating 14 and the buzzer 15 both communicate with the controller. When the grating 14 detects that foreign objects or human parts have been inserted into the equipment, the detection signal is transmitted to the controller, and the controller controls the buzzer 15 to alarm.

[0111] Optionally, a device operating terminal 13 is provided on the upper outer frame 1. The device operating terminal 13 is communicatively connected with the controller. The operator can modify the parameters set on the controller through the device operating terminal 13. The device operating terminal 13 is a touch operation screen.

[0112] Since gluing may generate corrosive gas, an exhaust fan 16 is provided on the upper outer frame 1. The exhaust port of the exhaust fan 16 is connected to the interior of the gluing equipment for exhausting the corrosive gas. The exhaust fan 16 is a vacuum pump.

[0113] In this embodiment, the controller is connected to the grating 14, buzzer 15, X-axis driver 505, X-axis position sensor 506, Z-axis driver 534, Z-axis position sensor 535, Y-axis driver 553, Y-axis position sensor 554, the cooling fin power switch, pressurization driver 471, rotation driver 65, and each servo motor and motor. In this embodiment, the controller is programmed using a PLC. The encoded program is used to receive and send signals / commands. This encoded program is considered existing technology and can be easily implemented using existing programming languages. It will not be described in detail here. The controller is mounted on the lower surface of the mounting platform plate 3.

[0114] The working principle of the glue coating equipment provided by the embodiment of the utility model is as follows:

[0115] After checking that the equipment is in good condition, place the workpiece 8 on the workpiece mounting rotating plate 63 and fix it by clamping it with the movable clamp 64, start the glue coating equipment and keep the glue supply between the glue storage container 48 and the double-liquid screw valve 41 unobstructed; the three-axis displacement device 5 drives the glue coating device 4 to move the glue dispensing needle 476 to the glue receiving container 70, and the servo motor connected to the double-liquid screw valve 41 works to push glue liquid A and glue liquid B into the mixing glue cylinder 42 for mixing and enter the glue dispensing needle 476 through the glue dispensing pipe 43, thereby discharging the glue. The air in the needle 476 causes the glue to fill the glue discharge needle 476, and the three-axis displacement device 5 drives the glue coating device 4 to move again to place the glue discharge needle 476 coated with glue on the surface of the workpiece 8. The three-axis displacement device 5 moves at a uniform speed, so that the glue discharge needle 476 can evenly coat the glue on the surface of the workpiece 8. When the glue coating on one side of the workpiece 8 is completed, the rotating drive part 65 works to drive the workpiece mounting rotating plate 63 to rotate, thereby completing the flipping of the workpiece 8, and the glue discharge needle 476 continues to coat the workpiece 8 with glue through the glue coating channel.
