[0002] Various small hardware components for electronic products are produced in independent batches and are complex and varied. They need to be uniformly packaged after stamping, and then stored and transported. For smaller hardware components, carrier tape packaging is usually used to facilitate subsequent automated continuous assembly production.

[0003] Currently, the existing technologies for distinguishing the orientation of small hardware products and packaging them with carrier tape mostly involve workers using tools such as tweezers to clamp the small hardware products into the carrier tape, then covering them with the tape for sealing, and relying on the naked eye to identify the product orientation during the process.

[0004] However, during operations, workers may inevitably miss products due to emotional or physical fatigue, or they may mistakenly install small hardware products in the wrong direction, requiring rework and significantly reducing production efficiency, even leading to defective products being shipped out.

The first material taking assembly can be divided into a fixed part 133, a limiting rod 134, a lifting rod 135, a negative pressure material taking head 136, and a lifting driving structure for driving the lifting rod 135 to lift. The fixed part 133 is fixedly connected with the first carousel 131, the limiting rod 134 and the lifting rod 135 are both arranged through the fixed part 133 and are in sliding connection with the fixed part 133, the lower end of the limiting rod 134 and the lower end of the lifting rod 135 are both fixedly connected with the negative pressure material taking head 136, and a first return spring 137 is further sleeved on the lifting rod 135. The limiting rod 134 is used to ensure the stability of the negative pressure material taking head 136 when it moves relative to the fixed part 133, and the first return spring 137 is used to assist the negative pressure material taking head 136 to return. The negative pressure material taking head 136 in the embodiment adopts a negative pressure material taking mode to take materials, and then releases the materials by canceling the negative pressure.

The cam structure is used to push the negative pressure material taking head 136 to descend in height, to suck the product, and to reset the negative pressure material taking head 136 by the first reset spring 137, so that the structure at the position is compact, the contact surface is convenient for lubrication, and stability in the working process is improved.

[0060] The product direction identification module comprises a first distribution turntable mechanism, a second distribution turntable mechanism and a rotating positioning mechanism for adjusting the product orientation, the rotating positioning mechanism is located between the first distribution turntable mechanism and the second distribution turntable mechanism, and a positioning CCD image mechanism 31 for identifying the product direction is further arranged between the flexible vibration disc 12 and the first distribution turntable mechanism or the second distribution turntable mechanism. The first distribution turntable mechanism and the second distribution turntable mechanism both comprise distribution discs 81 and distribution rotating motors 82, and the two distribution discs 81 are driven to rotate by the two distribution rotating motors 82 respectively. Two distribution discs 81 are designed to store more products and reduce the waiting time of the second material taking turntable mechanism when the second material taking turntable mechanism picks up the products, so that the working efficiency of the embodiment is improved. A plurality of material taking grooves 83 are arranged on the two distribution discs 81 and are distributed in the circumferential direction respectively, a material taking hole 84 for inserting a material taking head is arranged at the bottom of each material taking groove 83, so that the material taking rod 633 in the second material taking turntable mechanism can be inserted into the material taking hole 84 when there is no product in the material taking groove 83, and collision between the material taking rod 633 and the bottom of the material taking groove 83 is avoided.

[0061] In addition, the carrier tape packaging module mainly comprises a film feeding mechanism 41, a carrier tape mechanism 42, a tape sealing mechanism 43 and a tape conveying mechanism 44 which are connected with each other and work together. The products which are corrected and detected by the second material taking turntable mechanism are placed on the carrier tape mechanism 42, and then are conveyed to the tape sealing mechanism 43 by the carrier tape guide wheel at the rear of the carrier tape mechanism 42 and the cover tape guide wheel arranged in front of the filling position, and are sealed by the tape sealing mechanism 43, and finally are collected by the tape conveying mechanism 44, so that the packaging is completed. The second material taking turntable mechanism and a pneumatic mechanism 45 for cooperating with the second material taking turntable mechanism are arranged on the tape sealing mechanism 43. The pneumatic mechanism 45 mainly comprises a fixed support and related pneumatic components for connecting a negative pressure machine and other equipment.

[0062] The rotating positioning mechanism in the embodiment mainly comprises a base 51 and a plurality of clamping pieces 52. A plurality of accommodation grooves 53 are formed in the upper portion of the base 51. Each rotating connecting rod 54 is correspondingly arranged in each accommodation groove 53. The middle portion of the rotating connecting rod 54 is hinged to the accommodation groove 53, and is installed in a lever structure. A rotating reset spring 55 is arranged between the lower portion of the rotating connecting rod 54 and the accommodation groove 53. In the default state, the rotating positioning mechanism can be in a clamping state. Each clamping piece 52 is correspondingly arranged on the top portion of the rotating connecting rod 54. An abutting rotating wheel 56 is arranged on the rotating connecting rod 54. The abutting rotating wheel 56 is located between the hinge point of the rotating connecting rod 54 and the clamping piece 52. An abutting through hole 57 is formed in the bottom portion of the base 51. An abutting column 58 for pushing the abutting rotating wheel 56 is arranged in the abutting through hole 57. An abutting driving mechanism for driving the abutting column 58 to reciprocate in the abutting through hole 57 is arranged on the bottom portion of the base 51. Through the reciprocating movement of the abutting column 58, each abutting rotating wheel 56 can be squeezed, so as to realize the swinging of each rotating connecting rod 54, and the clamping and loosening state of each clamping piece 52 is switched. The abutting ring can reduce the collision force of the abutting column 58, provide a certain degree of buffer, convert sliding friction into rolling friction, reduce wear and tear, and prolong the service life.

[0063] In addition, in order to realize the adjustment of the product angle, a rotating mechanism for driving the base 51 to rotate is arranged on the rack 1. The base 51 is a center-symmetrical structure, which ensures that the center position of the product is not changed by rotation. Each rotating connecting rod 54 and each clamping piece 52 are uniformly arranged in the circumferential direction with the center axis of the base 51 as the center. The rotating positioning mechanism has a compact overall structure, a short working stroke and high efficiency. In terms of the abutting driving mechanism, the abutting driving mechanism specifically comprises an abutting cam 591 and an abutting driving motor 592 for driving the abutting cam 591 to rotate. Through the rotation of the abutting cam 591, the abutting column 58 is driven to reciprocate up and down. The upper portion of the abutting column 58 is a rotating structure, so that each abutting rotating wheel 56 does not interfere with the abutting column 58 when the base 51 rotates. The surface of the abutting column 58 and each abutting rotating wheel 56 abuts against is provided with an arc-shaped recess structure for accommodating part of the structure of the abutting rotating wheel 56, so that the internal structure of the base 51 is more compact, and the occupied space is saved.

[0064] Due to the coincidence with the abutment column 58 structure, in order to further improve the compactness and integrity of the structure, the rotating mechanism part of the embodiment specifically includes rotating disc 5931, fixed seat 5932, rotating bearing 5933, rotating column 5934 and synchronous pulley 5935 arranged at the lower part of the base 51. The rotating disc 5931 is connected with the fixed seat 5932 through the rotating bearing 5933. The rotating column 5934 is located at the lower part of the rotating disc 5931. The synchronous pulley 5935 is sleeved on the rotating column 5934. The rack 1 is provided with a synchronous belt mechanism for linkage of the synchronous pulley 5935 rotation. The abutment cam 591 is located at the lower part of the synchronous pulley 5935. The abutment column 58 is arranged through the center of the rotating mechanism and coaxially arranged with the rotating mechanism. The abutment column 58 is arranged through the center of the rotating mechanism and can be left with a gap or abutment with the center of the rotating mechanism. The embodiment is not limited.

[0065] Due to the position of the rotating hardware and other products relative to the suction nozzle will change during the feeding process, the four-jaw positioning mechanism is needed for repositioning. Therefore, in order to realize the position judgment of the hardware and other products, the lateral CCD image mechanism 32 and the bottom CCD image mechanism 33 are arranged below the second material taking turntable mechanism. The bottom CCD image mechanism 33 is provided with a mirror for realizing the shooting of the bottom of the product. The four-jaw positioning mechanism is arranged on one side of the lateral CCD image mechanism 32 and the bottom CCD image mechanism 33 for positioning the product. The four-jaw positioning mechanism has two. The main turntable mechanism is arranged between the two four-jaw positioning mechanisms. The main turntable mechanism is an optional mechanism during the feeding process, which is used for rotating the direction of the product, facilitating the user to cooperate with the use of different carrier tapes, and rotating the product to any direction.

[0066] The four-jaw positioning mechanism specifically comprises a positioning driver 91, a positioning four-jaw chuck 92 located on the positioning driver 91, four positioning clamping jaws 93 located on the positioning four-jaw chuck 92, and four positioning contact heads 931. The positioning four-jaw chuck 92 comprises a chuck base, a chuck sliding groove 94 provided on the chuck base, and a chuck cam 95. The vertical projection surface of the chuck sliding groove 94 is in the shape of a cross. Each positioning clamping jaw 93 is embedded in the chuck sliding groove 94 in one-to-one correspondence and is in sliding connection with the inner wall of the chuck sliding groove 94. Since the number of the positioning clamping jaws 93 is four, the chuck cam 95 is designed in a polygonal structure in the present embodiment and is located at the center of the chuck base. The corners are rounded. The chuck cam 95 can be rotated to expand the clamping range of the four positioning clamping jaws 93. Since the positions of different products for taking materials are different, the positions of the chuck cam 95 protruding at different angles determine the travel of the positioning clamping jaws 93. The positioning clamping jaws 93 can be centered on the rotation axis of the chuck cam 95. In the working process, the clamping area is first opened, then the travel is slightly reset, the product is clamped, and finally the product is moved as a whole to adjust and position the product. Since the chuck cam 95 needs to make the four positioning clamping jaws 93 displace by different travels, the side surface of the chuck cam 95 needs to be designed in a polygonal structure with four orientations (a pulley is further arranged on the positioning clamping jaw 93 to abut against the chuck cam 95, so as to change the sliding friction into rolling friction, reduce the wear of the chuck cam 95, and improve the stability of the equipment operation and the positioning accuracy). The positioning clamping jaws 93 are reset by the springs arranged thereon, which will not be described herein again. The output shaft of the positioning driver 91 is fixedly connected with the chuck cam 95 to realize linkage.

[0067] The sizes of different products are different. In order to improve the applicability of the present embodiment, an adjusting sliding groove 96 is arranged on the positioning clamping jaw 93. Each positioning contact head 931 is fixed in the adjusting sliding groove 96 in one-to-one correspondence and can be adjusted in relative position by the strip-shaped hole and the fastener at the current position of the positioning clamping jaw 93, so as to realize accurate clamping of different products. Specifically, the main rotating disc mechanism in the present embodiment comprises a positioning rotating column 97 fixed on the rack 1 and a main positioning groove 98 provided on the positioning rotating column 97. The lower part of the positioning rotating column 97 is provided with a main rotating motor 99 for driving the rotation of the positioning rotating column 97.

[0068] The second material taking turntable mechanism in the embodiment specifically comprises a second turntable 61, a plurality of second material taking assemblies arranged on the second turntable 61, and a turntable driving motor 62 for driving the second turntable 61 to rotate, which can be a speed reduction motor with a speed reduction mechanism for controlling the output number of rotations. Each second material taking assembly is arranged around the central axis of the second turntable 61. The second material taking assembly comprises a connecting piece 631, a positioning block 632, a material taking rod 633, and a guide rod 634. The connecting piece 631 is in the shape of an "L" (space-saving, large installation area, and stable structure) and is fixedly connected with the second turntable 61. The positioning block 632 is arranged on the upper portion of the connecting piece 631. One end of the guide rod 634 and one end of the material taking rod 633 are fixedly connected with the positioning block 632. The guide rod 634 is mainly used for limiting and improving the stability of the material taking rod 633 during the lifting process. The other end of the material taking rod 633 and the other end of the guide rod 634 pass through and are slidingly connected with the connecting piece 631. A material taking head is arranged on the lower portion of the material taking rod 633 for abutting against products and sucking the products through negative pressure. A second return spring 635 is sleeved on the material taking rod 633 and abuts against the connecting rod. The second return spring 635 is mainly used for returning the material taking rod 633 downward. During the working process of the second turntable 61, each material taking rod 633 needs to be correspondingly matched with each mechanism for synchronous work. Since the working heights of the mechanisms are different, the material taking rod 633 that first abuts against the products needs to slide relative to the second turntable 61 during the lowering process of the second turntable 61, so that the second turntable 61 can continue to move downward and drive the remaining material taking rods 633 that do not abut against the products to continue to move downward. After the height of the second turntable 61 is reset, the second return spring 635 pushes each material taking rod 633 to reset, so as to realize the simultaneous taking or placing of the material taking rods 633 at different heights. Since the material taking rod 633 needs to suck the products through negative pressure, an air vent 636 is arranged on the upper portion of the material taking rod 633 for connecting a corresponding air pipe. An upper positioning structure is further arranged on the second turntable 61 for abutting against the second turntable 61 and improving the rotation stability of the second turntable 61 in the default state. The upper positioning structure specifically comprises a positioning column, a main air vent interface, and a plurality of auxiliary air vent interfaces. Each auxiliary air vent interface is correspondingly matched with each material taking rod 633 and is connected through an air pipe. The main air vent interface is used for connecting a negative pressure machine and is connected with each auxiliary air vent interface. When the second turntable 61 is lowered, each auxiliary air vent interface is connected with each material taking rod 633 through an air pipe with a length allowance. The lower portion of the positioning column can abut against the upper portion of the second turntable 61 and is provided with a rubber abutting ring and other buffering components to reduce the abrasion between the positioning column and the second turntable 61.

[0069] The rotary table driving motor 62 is arranged on the frame 1, and the horizontal height of the lower part of each material taking rod 633 is higher than the horizontal height of the four-jaw positioning mechanism, the rotary positioning mechanism, the main rotary table mechanism, the first material distributing rotary table mechanism and the second material distributing rotary table mechanism. Through changing the height of each material taking rod 633 during the descending of the second rotary table 61, each material taking rod 633 can complete the operation.

[0070] In order to realize the descending of the second rotary table 61, the lifting module for driving the second rotary table 61 to ascend and descend is arranged on the rotary table driving motor 62. Specifically, the lifting module comprises a lifting seat 71, a lifting column 72 and a lifting driver 73. The lifting seat 71 is arranged on the frame 1. The lifting column 72 is in sliding connection with the lifting seat 71. A cylindrical spur gear 74 is arranged in the lifting seat 71. The two ends of the cylindrical spur gear 74 are fixedly connected with the output shaft of the lifting driver 73 and the lower part of the second rotary table 61, respectively. The second rotary table 61 is driven to ascend and descend by the lifting driver 73. When the second rotary table 61 ascends and descends, the top of the lifting seat 71 is embedded in the lifting column 72. The lifting column 72 and the lifting seat 71 are in sliding connection. In addition, a driving spur gear 75 is sleeved on the output shaft of the rotary table driving motor 62. The driving spur gear 75 is engaged with the cylindrical spur gear 74. Through the operation of the rotary table driving motor 62, the driving spur gear 75 and the cylindrical spur gear 74 are driven to rotate. By virtue of the structural characteristics of the driving spur gear 75 and the cylindrical spur gear 74, the cylindrical spur gear 74 can always be engaged with and linked with the driving spur gear 75 during the lifting process.

[0071] In order to improve the working efficiency of the second rotary table 61, the carrier tape mechanism 42, the two four-jaw positioning mechanisms, the main rotary table mechanism, the first material distributing rotary table mechanism and the second material distributing rotary table mechanism should be located in the operation range of the second material taking rotary table mechanism. Through the cyclic rotation of the second rotary table 61, the material taking rods 633 pass through the carrier tape mechanism 42, the two four-jaw positioning mechanisms, the main rotary table mechanism, the first material distributing rotary table mechanism and the second material distributing rotary table mechanism in turn according to the feeding sequence. The material taking rods 633 continuously take and place materials, shorten the moving range of the second rotary table 61 and the material taking rods 633, reduce unnecessary actions, shorten the time interval between actions, and greatly improve the working efficiency of the embodiment.

[0072] The working process of the embodiment is as follows. The product from the previous process enters the flexible vibration disc 12, and then the position information of the product is obtained by the CCD image mechanism on the flexible vibration disc 12. The product is picked up by the first material taking rotary table mechanism, and the orientation information of the product is obtained by the alignment CCD image mechanism 31 during the movement. The product is placed in the rotary positioning mechanism, and the product is rotated by the rotary positioning mechanism. After the product is adjusted to the set orientation, the product is transported to the first material distributing rotary table mechanism or the second material distributing rotary table mechanism by the first material taking rotary table mechanism.

[0073] At this time, the second turntable 61 in the second pick-up turntable mechanism is in a reciprocating working process of continuous rotation, lifting, re-rotation, and re-lifting, picks up the product in the first or second sub-turntable mechanism, then sequentially places the product in the four-jaw positioning mechanism for positioning, adjusts the relative position between the product and the pick-up rod 633, then places the product into the main turntable mechanism to correct the direction, then places the product into another four-jaw positioning mechanism for secondary positioning, and finally sends the product to the filling position of the carrier tape mechanism 42 to complete the feeding and enter the carrier tape packaging link. The positions of the lateral CCD image mechanism 32 and the bottom CCD image mechanism 33 are installed between the processes of the two four-jaw positioning mechanisms, and the image detection is performed once after the product enters the main turntable mechanism and the main turntable mechanism, respectively, to ensure the accurate position of the product relative to the pick-up rod 633 and ensure the product is intact, improve the efficiency of feeding, and reduce the risk of carrier tape packaging of defective products.

[0074] Each CCD image mechanism in the embodiment is connected with the control system of the equipment, acquires and analyzes the graphic information under the control of the control system, then interacts with each driver through calculation and judgment, and is equipped with corresponding light supplementing equipment, mirrors, etc. to improve the acquisition quality and efficiency of the graphic information. Each driver in the embodiment is preferably a servo motor, which has high precision and reliable operation. The negative pressure pick-up head 136 and the pick-up rod 633 can be replaced with appropriate pick-up structures according to the structural characteristics of different products, and the embodiment will not be described again.

[0075] The above-described embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application all belong to the scope of protection required by the present application.
