Abstract
Description
Technical Field
[0001] This invention relates to a pin-type contact insertion machine, comprising a conveying unit for conveying a pin-type contact strip having a plurality of interconnected pins arranged parallel to each other; a separating device for separating the pins from the pin-type contact strip; a placing device for performing a placing stroke for placing the pins separated from the pin-type contact strip into a plastic component; the conveying unit, the separating device, and the placing device being configured to place the pins separated from the pin-type contact strip into the plastic component according to a predetermined clock pulse; and a removing device being configured to perform a deflection motion as part of the placing stroke according to the predetermined clock pulse. Furthermore, this invention also relates to a method for placing pins into a plastic component. Background Technology
[0002] A pin-type contact insertion machine is used, for example, to equip plastic housings manufactured by injection molding with pin-type contacts. This assembly is professionally referred to as "placement" or "stitching." In this case, for example, three hundred pin-type contacts are placed into the corresponding supplied plastic housings at a fully automated rate. The pin-type contacts to be placed are typically supplied as pin-type contact strips and are separated into individual pieces from the strips before placement.
[0003] It is known that in such needle contact insertion machines, the individual movements required for the process steps of "supply," "separation," and "placement" are synchronized by means of a mechanical coupling via a cam disc or spindle. Here, the drive is centrally performed by a single motor, whose rotational motion is converted into the necessary conveying, separating, and reciprocating movements by means of mechanical coupling. Using this mechanical coupling has the advantage that the synchronization of the various working steps of a pulse is mechanically predetermined and works reliably even for high equipment frequencies or high pulse numbers. However, a disadvantage in this case is that the possibility of individually adapting the individual movements of the mechanical coupling is very limited or even nonexistent. Summary of the Invention
[0004] In this context, the technical problem of the present invention is to provide a pin-type contact insertion machine of the type described at the beginning of this document, which enables improved control of the process steps for automatically placing pin-type contacts, and in particular, enables individual control of the process steps for automatically placing pin-type contacts. Furthermore, an improved method for placing pin-type contacts into plastic components should also be provided.
[0005] The aforementioned technical problems are solved by utilizing the features of the independent claims. Other embodiments of the invention are derived from the dependent claims and the following description.
[0006] According to a first aspect, the present invention relates to a pin-type contact insertion machine, the pin-type contact insertion machine having a conveying unit for conveying a pin-type contact strip having a plurality of interconnected pin-type contacts arranged parallel to each other, the pin-type contact insertion machine having a separating device for separating the pin-type contacts from the pin-type contact strip, the pin-type contact insertion machine having a placing device for performing a placing stroke for placing the pin-type contacts separated from the pin-type contact strip into a plastic component, the conveying unit, the separating device and the placing device being configured to place the pin-type contacts separated from the pin-type contact strip into the plastic component according to a predetermined clock pulse, the placing device having a taking-out device being configured to perform a deflection motion as part of the placing stroke according to the predetermined clock pulse. The pin-type contact insertion machine is characterized in that the placement device has a first servo motor drive device, the first servo motor drive device being configured to perform a linear stroke as part of the placement stroke for placing the pin-type contact according to the predetermined clock pulse, the conveying unit has a second servo motor drive device, the separating device has a third servo motor drive device, and the taking-out device has a fourth servo motor drive device.
[0007] Therefore, the conveying unit, the separating device, and the placing device each have at least one independent drive and can thus be controlled separately and independently of each other. In particular, there is no mechanical coupling between the conveying unit, the separating device, and the placing device. Therefore, the kinematic characteristics (i.e., displacement and time, or stroke and pulse) of the conveying unit, the separating device, and the placing device can be controlled independently and separately of each other.
[0008] Therefore, for example, the travel depth or travel time, acceleration or speed of the placement device can be adapted without affecting the kinematic characteristics of the separating device and / or the conveying unit, or vice versa. Therefore, the corresponding kinematic characteristics of the separating device and / or the conveying unit can also be adjusted individually.
[0009] Compared to fixed, predetermined mechanical couplings, separate, independent servo motor drives offer advantages such as improved adjustability and lower maintenance costs. Furthermore, the number of mechanical components can be reduced.
[0010] When this document refers to separating the pin contacts from the pin contact strip, it refers to dividing the pin contacts into individual units. Therefore, after separation or division into individual units, there is no material-locking relationship between the respective separated or divided individual pin contacts and their corresponding previously adjacent pin contacts in the pin contact strip. Thus, after separation or division into individual units, each of the separated or divided individual pin contacts exists as a single pin contact.
[0011] Each of the pin contacts may have a flange as an integral component, which, during placement, supports the pin contact to the slider or placement head of the placement device. The flange may taper tapered along the placement direction. The flange may have a profile for locking onto the plastic component in the placement state. The flange may be constructed as a Christmas tree-shaped locking profile that, after placement, is embedded in or locked within the material of the plastic component.
[0012] The placement device can be configured to individually place each pin contact, which is separated or divided into individual pins, into the plastic component to be fitted using separate placement strokes. Thus, for example, ten or more pin contacts can be sequentially placed into the plastic component to be fitted using ten or more separate placement strokes.
[0013] The placement device can be configured to simultaneously place multiple pin contacts into a plastic component to be fitted using a single placement stroke. For example, up to six pin contacts, separated or divided into individual pins, can be simultaneously placed into the plastic component to be fitted using a single placement stroke. Therefore, placing, for example, twenty pin contacts requires, for example, four placement strokes, in which five pin contacts, separated or divided into individual pins, are simultaneously placed into the plastic component to be fitted using each of the four placement strokes. In this case, the pin contacts to be placed simultaneously can be separated into individual pins using a separating device using a single stamping stroke and provided to the placement device.
[0014] Therefore, for each placement stroke, the conveying unit and the separating device can supply the placement device with a single pin contact that is separated or divided into individual pin contacts, or with multiple pin contacts that are separated or divided into individual pin contacts.
[0015] Currently, the placement stroke is a superimposed movement of the first servo motor drive and the fourth servo motor drive. The first servo motor drive provides the linear stroke, which ensures the pin contact to be placed is firmly fixed in the plastic component to be fitted, while the fourth servo motor drive adds a deflection motion to this linear stroke, particularly for the return stroke after the pin contact has been placed. This deflection motion of the removal device causes the placement device to decouple from the pin contact placed in the plastic component. Therefore, it can be ensured that the pin contact placed in the plastic component is not pulled out of the plastic component during the return stroke.
[0016] The pin-type contact insertion machine can be configured to place up to four hundred pins per minute. Specifically, it can be configured to place up to five hundred pins per minute. Compared to known solutions utilizing mechanical coupling (e.g., in the case of using a spindle with a cam disk), using a separate servo motor drive enables an increase in the clock pulse speed.
[0017] The pin-contact insertion machine can be used to assemble various plastic components. Therefore, for example, it can be used to manufacture or assemble pin-contact plug arrays, plug connectors, bases, pin arrays, encapsulated or packaged plug connectors, socket arrays, preforms, etc. The pin-contact insertion machine can also be used to assemble preforms, which are then supplied to an injection molding machine after being equipped with pin contacts and injection-encapsulated in the assembled state.
[0018] The first servo motor drive device can be a linear servo motor, which can be configured to perform a linear stroke according to the predetermined clock pulse as a portion of the placement stroke for placing the pin contact. Here, in particular, the linear stroke is directly actuated by the stroke piston of the linear servo motor, without mechanically converting or reversing the movement of the stroke piston. Therefore, the linear servo motor can act as a direct drive device to directly generate the linear stroke as a portion of the placement stroke for placing the pin contact.
[0019] The second servo motor drive can be a rotary servo motor. Here, the rotary adjustment motion can be converted into linear conveying motion by means of mechanics. Alternatively, the second servo motor drive can also be a linear servo motor.
[0020] The third servo motor drive can be a rotary servo motor. Here, the rotary adjustment motion can be converted into linear separation or stamping motion by means of mechanics. Alternatively, the third servo motor drive can also be a linear servo motor.
[0021] The fourth servo motor drive can be a rotary servo motor. Here, an eccentric wheel can be used to convert the rotary adjustment motion into upward and downward motion, or deflection motion. Alternatively, the fourth servo motor drive can also be a linear servo motor.
[0022] The rotary servo motor may, for example, have one or more of the following characteristics: a rated speed of up to 6000 rpm; a torque of 0.5 Nm to 10 Nm; and a torque of less than or equal to 1.0 kg / cm². 2 The moment of inertia.
[0023] The pin-type contact insertion machine may have a device for supplying and positioning plastic components, the device being configured to position a single plastic component relative to the placement device, and the device having a fifth servo motor drive. Each of the various plastic components may be equipped with multiple pin contacts. Here, it can be specified that the placement device always supplies the pin contacts to be placed to the same location, while the fifth servo motor drive performs an indexing movement corresponding to or a multiple of the minimum placement spacing of adjacent pin contacts in the plastic component, and in this way assembles the plastic components sequentially with pin contacts.
[0024] The fifth servo motor drive device can be a linear drive device or a linear servo motor.
[0025] The device for supplying and positioning the plastic components may have a sixth servo motor drive. The sixth servo motor drive may be a linear drive or a linear servo motor.
[0026] The fifth and sixth servo motor drive units can be oriented perpendicularly to each other and, in particular, constitute a cross-shaped drive unit. In this way, the plastic component can be moved in a grid pattern according to the predetermined assembly positions of the pin contacts and is partially or completely equipped with pin contacts in rows and columns.
[0027] The needle contact insertion machine may have a control device for operating the first servo motor drive, the second servo motor drive, the third servo motor drive, and the fourth servo motor drive according to the predetermined clock pulse. In particular, it does not provide mechanical coupling (such as cam disk, spindle, etc.) but provides virtual coupling to control the movement of the placement device, the conveying unit, and the separation device.
[0028] The first servo motor drive, the second servo motor drive, the third servo motor drive, and the fourth servo motor drive can be synchronized according to the predetermined clock pulse using the software of the control device, and the control device can form a "virtual spindle".
[0029] For example, the concept of a virtual spindle can be implemented within the control device by pre-setting pulses for a single virtual axis module of the control device using a virtual guide axis (also called a virtual host). Each servo motor drive in the servo motor drive system can be equipped with its own virtual axis module, which controls the servo motor drive involved. The virtual axis module (also called a virtual slave axis) controls the motion of the corresponding servo motor drive within the pulses pre-set by the virtual guide axis.
[0030] In other words, the motion of the servo motor drive is virtually coupled or virtually synchronized. In this way, the increase or decrease of a predetermined pulse on the guide shaft automatically results in the adaptation of the motion process of all servo motor drives according to the predetermined virtual coupling.
[0031] Similarly, the control device may be configured to operate the fifth servo motor drive device and / or the sixth servo motor drive device according to the predetermined clock pulse.
[0032] In other words, the fifth servo motor drive and / or the sixth servo motor drive can also be synchronized within the predetermined clock pulse by means of the control device. In this case, in particular, the concept of the virtual spindle can be transformed.
[0033] Another advantage of the virtual coupling of the servo motor drive is that the servo motor drive can be easily decoupled from and coupled to the guide shaft using the software. Therefore, compared to a fixed, predetermined mechanical coupling, no mechanical intervention is required, or rather, no mechanical coupling or decoupling is necessary.
[0034] For example, the device for supplying and positioning the plastic component can be decoupled from the guide shaft in a controllable manner during loading of the plastic component to be equipped and during unloading of the equipped plastic component.
[0035] As already explained, the first servo motor drive can be a linear servo motor, which can be configured to perform a linear stroke as a portion of the placement stroke for placing the pin contact according to the predetermined clock pulse. The control device can be configured to monitor and adapt the stroke depth of the linear servo motor. Therefore, the stroke depth of the placement stroke can be controlled independently.
[0036] For example, it can be specified that different insertion depths of the pin contacts to be placed in the plastic component can be achieved. This can be achieved via a mechanical spindle using the control device. The stroke depth of the linear servo motor can be a maximum of 100 mm, preferably a maximum of 80 mm. The stroke depth can also be referred to synonymously as the displacement of the linear servo motor.
[0037] It can be specified that the stroke piston of the linear servo motor is guided by a sliding bearing. In this way, the stroke piston can be stabilized during the placement process.
[0038] The placement device may have a placement head with a single slot for receiving a pin contact separated from the pin contact strip, or the placement head may have multiple parallel slots, each for receiving a pin contact separated from the pin contact strip. Specifically, the placement head may have up to six or exactly six slots, each for receiving a pin contact separated from the pin contact strip. Therefore, each slot can accommodate a pin contact separated from the pin contact strip.
[0039] Therefore, a placement head with, for example, six slots can be equipped with one or more pin contacts for each placement stroke, depending on the assembly requirements, i.e., equipped with a maximum of six pin contacts.
[0040] The placement head is configured to slide the pin contact to be placed into the plastic component. For this purpose, the placement head forms a stop against which the pin contact to be placed rests during the placement process. Therefore, the placement head is used to transmit the force and stroke of the first servo motor drive to the pin contact to be placed.
[0041] According to a second aspect, the present invention relates to a method for placing pin contacts into a plastic component, wherein the following method steps are performed using a pin contact insertion machine according to the invention: conveying a pin contact strip by means of the conveying unit; separating the pin contacts from the pin contact strip by means of the separating device; placing the pin contacts into the plastic component by means of the placing device; and controlling a first servo motor drive, a second servo motor drive, a third servo motor drive, and a fourth servo motor drive according to a predetermined clock pulse.
[0042] The pin contacts separated from the pin contact strip can be individually and sequentially placed into the plastic component, with the placement device performing separate placement strokes for each pin contact to be placed.
[0043] Alternatively, two or more individual pin contacts separated from the pin contact strip can be simultaneously placed into the plastic component, with the placement device performing a common placement stroke for the pin contacts to be placed simultaneously.
[0044] The plastic component can be manufactured by injection molding.
[0045] The plastic component may be a preform, and after the pin contacts are placed, the following steps may be performed: inserting the preform equipped with the pin contacts into an injection molding die; and injecting plastic into the preform equipped with the pin contacts to form a housing that accommodates the preform equipped with the pin contacts.
[0046] The preform can be a plastic sheet or a sheet-shaped plastic component.
[0047] It can be specified that: after the needle contact is placed and before injection encapsulation, other plastic components are assembled onto the preform, and the plastic components are supplied together with the assembled preform to the injection molding die for injection encapsulation.
[0048] Therefore, the method may include the following steps after placing the pin contacts and before inserting the preform equipped with the pin contacts into the injection molding die: assembling other plastic components onto the preform.
[0049] The other plastic components can be assembled onto the preform to secure pin contacts placed on the preform.
[0050] Therefore, the method may include the following steps after placing the pin contact and before inserting the preform equipped with the pin contact into the injection molding die: assembling other plastic components onto the preform and fixing the pin contact onto the preform by means of the other plastic components.
[0051] It can be specified that the pin contact bends after placement, i.e., while held on the preform. Assembling the other plastic components onto the preform can be used to fix the pin contact in its deformed state and / or to fix the deformed state of the pin contact.
[0052] It can be specified that other components, together with the pre-formed part, are housed within the injection molding die and injection-encapsulated in the formation of the housing. These other components may be, for example, threaded sleeves, clips, reinforcing elements, or similar members.
[0053] The housing can be constructed using an injection-encapsulated preform to form a connector having more than one hundred pins, particularly less than two hundred pins, with each pin contact constituting one of the pins. Attached Figure Description

[0066] Figure 1 A pin-type contact insertion machine 2 is shown. The pin-type contact insertion machine 2 has a conveying unit 4 for conveying pin-type contact strips 6.
[0067] The pin contact bar 6 has multiple interconnected pin contacts 8 arranged in parallel relative to each other.
[0068] The pin-type contact insertion machine 2 has a separating device 10 for separating the pin-type contacts 8 from the pin-type contact strip 6. The separating device 10 is a stamping device.
[0069] The pin-type contact insertion machine 2 has a placement device 12 for performing a placement stroke for placing pin contacts 8 separated from the pin contact bar 6 into the plastic component 14.
[0070] Plastic component 14 is a plastic housing manufactured by injection molding. Plastic component 14 does not have contacts that are injection-encapsulated by injection molding, but rather the plastic component is fitted with pin contacts 8 by means of a pin contact insertion machine 2.
[0071] The conveying unit 4, the separating device 10, and the placing device 12 are configured to place a plurality of pin contacts 8 into the plastic component 14 according to a predetermined clock pulse. Here, for each pulse, one or more pin contacts 8 are placed into the plastic component 14 at a predetermined insertion depth E. The placement of the pin contacts 8 is performed sequentially according to the predetermined clock pulse, with one or more pin contacts 8 placed for each pulse. For a single pin contact 8, the insertion depth E can be individually adjusted if necessary and thus varies within the plastic component.
[0072] The placement device 12 has a first servo motor drive 20. The first servo motor drive 20 is a linear servo motor. The first servo motor drive 20 is configured to perform a linear stroke according to the predetermined clock pulse as a placement stroke for placing the pin contact 8.

The fourth servo motor drive 24 is a rotary servo motor.
[0076] The extraction device 22 constitutes a suspension portion for the first servo motor drive unit 20. Here, the fourth servo motor drive unit 24 is configured as an eccentric wheel, which causes the first servo motor drive unit 20 to deflect. Therefore, the deflection motion, which is part of the placement stroke, can be superimposed on the linear stroke.
[0077] The pin-type contact insertion machine 2 has a device 26 for supplying and positioning plastic components 14, which is configured to position a single plastic component 14 relative to the placement device 12.
[0078] The device 26 for supplying and positioning the plastic component 14 has a fifth servo motor drive 28 and a sixth servo motor drive 30. The fifth servo motor drive 28 and the sixth servo motor drive 30 constitute a cross-shaped platform for positioning the plastic component 14.

[0080] The control device 32 demonstrates virtual coupling or virtual synchronization of the servo motor drive unit by means of a virtual spindle 34. The virtual spindle 34 is a virtual guide axis or virtual host with a predetermined clock pulse, within which the configured virtual axis modules are synchronized.
[0081] Each servo motor drive is equipped with its own virtual axis module, which individually controls the servo motor drive involved.
[0082] The first servo motor drive unit 20 is equipped with a first virtual axis module 36. The second servo motor drive unit 16 is equipped with a second virtual axis module 38. The third servo motor drive unit 18 is equipped with a third virtual axis module 40. The fourth servo motor drive unit 24 is equipped with a fourth virtual axis module 42. The fifth servo motor drive unit 28 is equipped with a fifth virtual axis module 44. The sixth servo motor drive unit 30 is equipped with a sixth virtual axis module 46.
[0083] Similarly, the supply of plastic component 14 can be performed via a servo motor drive, allowing the installation of a seventh servo motor drive 48 equipped with the provided seventh virtual axis module 50. Alternatively, the supply of plastic component 14 can be performed using a robot, such as a SCARA robot.
[0084] The fifth, sixth, and seventh servo motor drive units can be linear servo motors, respectively.
[0085] The first servo motor drive device 16 is a linear servo motor, which is configured to perform a linear stroke according to the predetermined clock pulse as part of the placement stroke for placing the pin contact 8.
[0086] The control device 32 is configured to monitor and adapt the stroke depth or insertion depth E of the linear servo motor 16.
[0087] The stroke piston 52 of the linear servo motor 16 carries a placement head 54 on its end side, which accommodates and places the separated pin contacts 8 into the plastic component 14 after they have been separated into individual pins. The placement head 54 may be configured to accommodate a single pin contact 8 or multiple pin contacts 8.
[0088] It can be specified that the separating device 10 is configured to simultaneously separate multiple pin contacts 8 from the pin contact strip using a single stamping stroke and to provide a placement head 54. In this case, the placement head 54 receives the separated multiple pin contacts 8 from the separating device 10 for each placement stroke and simultaneously places these pin contacts into the housing 14.
[0089] It can be specified that the separating device 10 is configured to separate a single pin contact 8 from the pin contact bar using a single stamping stroke and to provide a placement head 54. In this case, the placement head 54 receives the separated single pin contact 8 from the separating device 10 for each placement stroke and places the pin contact into the housing 14.
[0090] According to the present invention, the following method steps for using the needle contact insertion machine 2 are synchronized by means of the control device 32 according to the predetermined clock pulse. Figure 2 ):

[0095] As already discussed, it can be specified that for each individual pulse of the clock pulse, only one single pin contact 8 is split or separated from the pin contact strip 6 and placed thereon. According to an alternative embodiment, it can be specified that for each pulse of the clock pulse, multiple pin contacts 8 are split or separated from the pin contact strip 6 and placed thereon. In particular, it can be specified that for each pulse of the clock pulse, up to six pin contacts 8 are split or separated from the pin contact strip 6 and placed thereon.
[0096] Figure 3A A perspective view of the placement head 54 is shown. The placement head 54 is a slider and, in the assembled state, is coupled to the stroke piston 52 via its end section 58 and places the pin contacts 8 into the plastic component 14 involved. The placement head 54 has six slots 60 for positioning and guiding the pin contacts 8, which are divided into individual or separate pin contacts, during the placement stroke.
