Description

Technical Field

[0001] The utility model relates to the technical field of fastener production equipment, in particular to a drying and transfer device for chemical glue fasteners. Background Technique

[0002] The chemical glue used for fasteners and screws is usually called fastening glue or anaerobic sealant. This glue is mainly used to ensure that the screws will not fall off during operation.

[0003] After the chemical glue is coated on the threaded surface of the shaft part of the fastener, it needs to be dried and cured.

[0004] The problems existing in the prior art are as follows: The fasteners move along with the conveying device. After passing through the glue spraying device to spray the chemical glue, they need to be transferred to the drying equipment. At this time, the fasteners need to cross the conveying device for transfer. However, the fasteners on the conveyor line are fed adjacent to each other before and after, which easily causes the mechanical claws to misgrab the fasteners, such as the fasteners falling due to incorrect grasping positions, or the adjacent fasteners being misgrabbed and interfering with each other and falling.

[0005] Therefore, it is necessary to design a fastener transfer device to separate the originally closely adjacent fasteners one by one to form an orderly spaced arrangement, so as to more accurately grab the fasteners for transfer between devices. Summary of the Utility Model

[0006] In order to solve the above technical deficiencies, the utility model provides a drying and transfer device for chemical glue fasteners.

[0007] The further setting of the utility model: The drying and transfer device for chemical glue fasteners includes a feeding mechanism, two step tracks, a handling fork, a first driving mechanism and a discharging mechanical claw. The step track includes a feeding side, a discharging side and a receiving end face on one side vertically above. A plurality of first concave grooves are equidistantly spaced along the transmission direction on the receiving end face, and the equidistant spacing distance is A. The diameter of the first concave groove is adapted to the diameter of the shaft part of the fastener. The two step tracks are arranged in parallel at intervals with a gap in the middle. The feeding mechanism conveys the fasteners to the receiving end face, and the shaft part of the fastener makes a rolling fit with the receiving end face and falls into the first concave groove at the feeding side;

[0008] The handling fork is parallel to the step track and is arranged at the gap. A plurality of second concave grooves are arranged at intervals of distance A corresponding to the positions of the first concave grooves on the handling fork. The number of the second concave grooves is one less than the number of the first concave grooves;

[0009] The first driving mechanism is linked and cooperated with the handling fork to drive the handling fork to move along a quadrilateral motion track. This quadrilateral motion track drives the first second recessed groove on the feeding side of the handling fork to move upward from the initial position directly below the first first recessed groove on the feeding side, coincide with the first recessed groove and move out to the vertical upper side of the first recessed groove, then drive the second recessed groove to translate a distance A along the conveying direction to the vertical upper side of another first recessed groove adjacent in the conveying direction, then drive the second recessed groove to move downward, coincide with the first recessed groove and descend to the vertical lower side of the first recessed groove, and finally translate a distance A in the reverse conveying direction to return to the initial position;

[0010] The first driving mechanism drives the handling fork to reciprocate along a quadrilateral motion track, and drives the fasteners in the first first recessed groove on the feeding side to be transported one by one into the first recessed groove at the end of the discharging side. The discharging mechanical claw clamps the fasteners in the first recessed groove at the end of the discharging side and transfers them to the drying equipment.

[0011] Adopting the above technical solution, the feeding mechanism transports a batch of fasteners onto the stepping track. Conventionally, the feeding mechanism is a vibrating disk and a feeding track. The vibrating disk guides the fasteners onto the conveying track. After being sprayed with chemical glue by the glue spraying mechanism, the fasteners are introduced into the feeding side of the stepping track in a horizontal posture by twisting the direction of the track. There are many existing solutions for fastener transportation, which will not be exemplified here. Due to the design of the first recessed groove, among the numerous fasteners that enter the stepping track closely adjacent in batches, the first fastener will fall into the first first recessed groove and intercept the subsequent fasteners.

[0012] Then, in this application, through the quadrilateral motion track of the handling fork, the fasteners in the first first recessed groove on the feeding side are transported along the conveying direction into the second first recessed groove, and the numerous fasteners on the feeding side move forward to fill the position. Again, the first fastener after filling the position falls into the first first recessed groove to form an interception.

[0013] Under the reciprocating motion of the handling fork, the fasteners in each first recessed groove are transported one by one to the next first recessed groove until they reach the first recessed groove at the end of the discharging side. At this time, the discharging mechanical claw can accurately grasp the independent fasteners with fixed coordinate positions and separated from other fasteners, and transfer them to other equipment (such as drying equipment) for separate operation.

[0014] A further setting of the present utility model: The first driving mechanism is a double crank mechanism, including a frame, a first crank, a second crank, a connecting rod, and a motor. The first crank and the second crank are arranged at intervals on the frame for rotational cooperation. A synchronous belt is arranged between the first crank and the second crank. The connecting rod is vertically connected to the handling fork and is hinged to the crank arms of the first crank and the second crank. The motor is linked and cooperated with the first crank, and the connecting rod drives the handling fork to move along a quadrilateral motion track.

[0015] With the above technical solution, the first driving mechanism can adopt a conventional slide rail and slider structure, such as a constraint mechanism, and reciprocating driving elements such as driving piston cylinders are respectively arranged at the vertical slider and the horizontal slider, which can also form a quadrilateral movement trajectory for driving the handling fork.

[0016] However, this setting has a high cost and also requires controlling the slider stroke. Instead, the present application adopts the solution of a double crank mechanism, and through the cooperative design of the lengths of the connecting rod and the crank arm, the precise movement trajectory of the handling fork is realized. In comparison, the design cost of the double crank mechanism in cooperation with the handling fork is lower.

[0017] A further setting of the present utility model: The device further includes a constraint mechanism, which includes a frame, a horizontal slide rail, a horizontal slider, a vertical slide rail, a vertical slider, and a vertical support arm. The horizontal slide rail is fixedly connected to the frame. The horizontal slider reciprocates slidably along the horizontal slide rail and is fixedly connected to the vertical slide rail. The vertical support arm is perpendicularly connected to the handling fork, and a vertical slider is arranged on the vertical support arm. The vertical slider reciprocates slidably along the vertical slide rail.

[0018] With the above technical solution, through the arranged constraint mechanism, the quadrilateral movement trajectory of the handling fork is guided to be more stable.

[0019] A further setting of the present utility model: The device further includes two screw rod support seats respectively connected to two stepping tracks. The screw rod support seat includes a base, a guide rod, a screw rod, a screw nut, and a hand wheel. The two screw rod support seats drive the two stepping tracks to move parallelly closer or farther away.

[0020] With the above technical solution, the distance between the two stepping tracks is controlled by the screw rod support seat adjusted by the hand wheel to adapt to fasteners of different length specifications for adaptation adjustment.

[0021] A further setting of the present utility model: Outside one of the stepping tracks of the device, a guide plate is arranged in parallel at an interval. When the fastener rolls into the stepping track, the nut part of the fastener is located at the gap between the guide plate and the stepping track. The end of the guide plate on the feeding side is provided with a first introduction chamfer, and the end face directly above the guide plate is provided with a second introduction chamfer facing the side of the stepping track.

[0022] With the above technical solution, through the designed guide plate, the position of the nut part of the fastener is guided and restricted, so that the axial positions of the fasteners on the stepping track are unified.

[0023] A further setting of the present utility model: The guide plate is in an L shape and includes a vertical part and a horizontal part. The horizontal part is provided with an oblong hole in the direction of approaching or departing from the stepping track.

[0024] By adopting the above technical solution, the position of the guide plate is adjusted and adapted according to the axial thickness of the different nut parts.

[0025] Further configuration of the utility model: the discharging mechanical claw includes a pneumatic clamping claw and a second driving mechanism. The second driving mechanism is a double crank mechanism, including a frame, a first crank, a second crank, a connecting rod, and a motor. The first crank and the second crank are arranged on the frame at intervals for rotation cooperation. A synchronous belt is arranged between the first crank and the second crank. The connecting rod is fixedly connected to the pneumatic clamping claw and is hingedly connected to the crank arms of the first crank and the second crank. The motor is linked with the first crank, and the connecting rod drives the pneumatic clamping claw to perform a "冂"-shaped reciprocating motion trajectory.

[0026] With the above technical solution, the discharging mechanical claw is usually set up, and is also designed with slide rails, sliding seats, etc. This application uses a double crank mechanism to control the forward and reverse rotation angles of the servo motor to achieve reciprocating clamping action.

[0027] The synchronous belt improves the synchronous coordination between the first crank and the second crank, and a tensioning wheel can be provided corresponding to the synchronous belt.

[0028] The beneficial effects of the utility model: Through the design of the transfer device, the present application separates a large number of closely adjacent fasteners one by one, so that the mechanical claws can accurately grasp them and transfer them to other equipment such as drying for independent processing.

It can be understood that the specific embodiments described here are only partial embodiments of this application, which are only used to explain this application and not to limit this application. It should be noted that for the convenience of description, only the parts related to this application are shown in the drawings, and other related parts can refer to the general design.

[0036] The following introduces the present utility model in detail with reference to the drawings, as Figures 1 - 4 shown

[0037] A chemical glue fastener 9 drying and transfer device includes a feeding mechanism 81, two stepping tracks 1, a handling fork 2, a first driving mechanism 4 and a discharging mechanical claw 3. The stepping track 1 includes a feeding side 11, a discharging side 12 and a receiving end face 131 on one side above vertically. A number of first concave grooves 13 are arranged at equal intervals along the transmission direction on the receiving end face 131, and the equal interval distance is A. The diameter of the first concave groove 13 is adapted to the diameter of the shaft part of the fastener 9. The two stepping tracks 1 are arranged in parallel at intervals with a gap in the middle. The feeding mechanism 81 conveys the fastener 9 to the receiving end face 131, and the shaft part of the fastener 9 makes a rolling fit with the receiving end face 131 and falls into the first concave groove 13 at the first position of the feeding side 11;

[0038] The handling fork 2 is parallel to the stepping track 1 and is arranged at the gap. A number of second recessed grooves 21 are arranged on the handling fork 2 at a position corresponding to the first recessed groove 13 with a spacing distance A. The number of the second recessed grooves 21 is one less than the number of the first recessed grooves 13;

[0039] The first driving mechanism 4 is in linkage cooperation with the handling fork 2 to drive the handling fork 2 to move along a quadrilateral motion track. This quadrilateral motion track drives the first second recessed groove 21 on the feeding side 11 of the handling fork 2 to move upward from the initial position directly below the first first recessed groove 13 on the feeding side 11, coincide with the first recessed groove 13 and then move out to the vertical upper side of the first recessed groove 13, and then drive the second recessed groove 21 to translate a distance A in the conveying direction to the vertical upper side of another first recessed groove 13 adjacent in the conveying direction, and then drive the second recessed groove 21 to move downward, coincide with the first recessed groove 13 and then descend to the vertical lower side of the first recessed groove 13, and finally translate a distance A in the reverse conveying direction to return to the initial position;

[0040] The first driving mechanism 4 drives the handling fork 2 to reciprocate along a quadrilateral motion track, and drives the fasteners 9 in the first first recessed groove 13 on the feeding side 11 to be transported one by one into the first recessed groove 13 at the end of the discharging side 12. The discharging mechanical claw 3 clamps and takes out the fasteners 9 in the first recessed groove 13 at the end of the discharging side 12 and transfers them to the drying equipment.

[0041] The feeding mechanism 81 transports a batch of fasteners 9 onto the stepping track 1. Conventionally, the feeding mechanism 81 is a vibrating disk and a feeding track. The vibrating disk guides the fasteners 9 onto the conveying track. After being sprayed with chemical glue by the glue spraying mechanism, the fasteners 9 are introduced into the feeding side 11 of the stepping track 1 in a horizontal posture by means of the way of twisting the track. There are many existing schemes for transporting the fasteners 9, so no more examples will be given. Due to the design of the first recessed groove 13, among the numerous fasteners 9 that enter the stepping track 1 closely adjacent in batches, the first fastener 9 will fall into the first first recessed groove 13 and intercept the subsequent fasteners 9.

[0042] Then, in the present application, through the quadrilateral motion track of the handling fork 2, the fasteners 9 in the first first recessed groove 13 on the feeding side 11 are transported along the conveying direction into the second first recessed groove 13, and the numerous fasteners 9 on the feeding side 11 move forward to make up the position. Again, the first fastener 9 after making up the position falls into the first first recessed groove 13 to form an interception.

[0043] Under the reciprocating motion of the handling fork 2, the fasteners 9 in each first recessed groove 13 are transported one by one to the next first recessed groove 13 until they reach the first recessed groove 13 at the end of the discharging side 12. At this time, the discharging mechanical claw 3 can accurately grasp the independent fasteners 9 with fixed coordinate positions and separated from other fasteners 9 and transfer them to other equipment (such as drying equipment) for separate operations.

[0044] The first driving mechanism 4 is a double crank mechanism, including a frame 44, a first crank 41, a second crank 42, a connecting rod 43, and a motor. The first crank 41 and the second crank 42 are arranged at intervals on the frame for rotational cooperation. A synchronous belt 45 is arranged between the first crank 41 and the second crank 42. The connecting rod 43 is vertically connected to the handling fork 2 and is hinged to the crank arms of the first crank 41 and the second crank 42. The motor is in linkage cooperation with the first crank 41, and the handling fork 2 is driven by the connecting rod 43 to move along a quadrilateral trajectory.

[0045] The first driving mechanism 4 can adopt a conventional slide rail and slider structure, such as the constraint mechanism 5. Reciprocating driving elements such as driving piston cylinders are respectively arranged at the vertical slider 54 and the horizontal slider 52, and a quadrilateral movement trajectory for driving the handling fork 2 can also be formed.

[0046] However, this setting has a higher cost and also requires controlling the slider stroke. While the solution of the double crank mechanism is adopted in this application, and through the cooperative design of the lengths of the connecting rod 43 and the crank arms, the precise movement trajectory of the handling fork 2 is realized. In comparison, the design cost of the double crank mechanism in cooperation with the handling fork 2 is lower.

[0047] The device further includes a constraint mechanism 5, which includes a frame, a horizontal slide rail 51, a horizontal slider 52, a vertical slide rail 53, a vertical slider 54, and a vertical support arm 55. The horizontal slide rail 51 is fixedly connected to the frame. The horizontal slider 52 reciprocally slides along the horizontal slide rail 51 and is fixedly connected to the vertical slide rail 53. The vertical support arm 55 is vertically connected to the handling fork 2, and a vertical slider 54 is arranged on the vertical support arm 55. The vertical slider 54 reciprocally slides along the vertical slide rail 53.

[0048] Through the arranged constraint mechanism 5, the quadrilateral movement trajectory of the handling fork 2 is guided to be more stable.

[0049] The device further includes two screw rod support seats 6 respectively connected to the two stepping tracks 1. The screw rod support seat 6 includes a base 61, a guide rod 62, a screw rod 63, a screw nut 64, and a hand wheel 65. The two screw rod support seats 6 drive the two stepping tracks 1 to move closer or farther away in parallel.

[0050] The distance between the two stepping tracks 1 is controlled by the screw rod support seat 6 adjusted by the hand wheel 65 to adapt to fasteners 9 of different length specifications for adaptation and adjustment.

[0051] The device is provided with a guide plate 7 at intervals and in parallel on the outer side of one of the stepping tracks 1. When the fastener 9 rolls into the stepping track 1, the nut portion of the fastener 9 is located at the gap between the guide plate 7 and the stepping track 1. The end of the feed side 11 of the guide plate 7 is provided with a first introduction chamfer 71, and the end surface vertically above the guide plate 7 is provided with a second introduction chamfer facing the side of the stepping track 1.

[0052] The designed guide plate 7 guides and limits the position of the nut portion of the fastener 9 so that the axial positions of the fasteners 9 on the stepping track 1 are unified.

[0053] The guide plate 7 is L-shaped, including a vertical portion and a horizontal portion. The horizontal portion is provided with an oblong groove 72 in a direction close to or away from the stepping track 1 .

[0054] The position of the guide plate 7 is adjusted and adapted according to the axial thickness of the different nut parts.

[0055] The discharging mechanical claw 3 includes a pneumatic clamp 31 and a second drive mechanism 32. The second drive mechanism 32 is a double crank mechanism, including a frame, a first crank 41, a second crank 42, a connecting rod 43, and a motor. The first crank 41 and the second crank 42 are arranged on the frame at intervals for rotation cooperation. A synchronous belt 45 is arranged between the first crank 41 and the second crank 42. The connecting rod 43 is fixedly connected to the pneumatic clamp and is hinged to the crank arms of the first crank 41 and the second crank 42. The motor is linked with the first crank 41, and the connecting rod 43 drives the pneumatic clamp to perform a "冂"-shaped reciprocating motion trajectory.

[0056] The discharge mechanical claw 3 is conventionally configured with a slide rail, a sliding seat, etc., but this application uses a double crank mechanism to control the forward and reverse rotation angles of the servo motor to achieve a reciprocating clamping action.

[0057] The synchronous belt 45 improves the synchronization between the first crank 41 and the second crank 42 , and a tensioning wheel may be provided corresponding to the synchronous belt 45 .

[0058] The present application separates a large number of closely adjacent fasteners 9 one by one through the design of the transfer device, so that the mechanical claw can accurately grasp them and transfer them to other equipment such as drying for independent processing.

[0059] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the scope of protection of the present application.
