Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a multi-head dispensing device. Background Technology

[0002] Dispensing processes are widely used in fields such as electronic packaging. A typical dispensing apparatus includes an adsorption platform (to hold the workpiece), a dispensing head (to dispense adhesive from the bottom), and a dispensing drive unit (such as a robotic arm or XYZ module to drive the dispensing head). Despite its widespread use, existing apparatuses have significant limitations:

[0003] Current designs typically only configure a single dispensing head for operation. Regardless of the number of dispensing paths, all dispensing actions are performed sequentially by only one dispensing head at a time. This results in a long dispensing process, becoming a bottleneck for improving overall production cycle time, especially under high-volume or multi-point requirements, where the inefficiency problem is particularly prominent.

[0004] Therefore, existing dispensing devices need to be improved to solve the problem of low work efficiency caused by their single-head operation.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a multi-head dispensing device that can effectively solve the problem of low work efficiency caused by single-head operation in existing dispensing devices.

[0007] To achieve the above objectives, this utility model provides a multi-head dispensing device, comprising:

[0008] A workstation tray, wherein the workstation tray is provided with at least two dispensing workstations arranged sequentially along the length direction of the workstation tray;

[0009] A plurality of adsorption platforms are provided corresponding to each of the dispensing stations. Each adsorption platform includes a platform body for adsorbing workpieces and a platform direct drive assembly for driving the adsorption platform to move upward until the workpiece is removed from the station tray.

[0010] A material transfer robot is used to synchronously transfer all workpieces on the workstation pallet to the next adjacent dispensing station along the length of the workstation pallet.

[0011] A plurality of dispensing devices are provided in a one-to-one correspondence with each of the adsorption platforms. The dispensing devices are located above the corresponding adsorption platforms. Different dispensing devices are used to perform dispensing operations on different dispensing areas of the workpiece. All the dispensing devices work together to perform dispensing operations on all dispensing areas of the workpiece.

[0012] Optionally, the number of dispensing stations is four.

[0013] Optionally, the platform direct drive component includes:

[0014] A fixed base is fixedly disposed relative to the workstation tray;

[0015] A lifting slider is slidably connected to the fixed base, and the platform body is located above the lifting slider.

[0016] A slider direct drive mechanism is mounted on the fixed base, and the drive end is connected to the lifting slider to drive the lifting slider to slide upward.

[0017] A reset spring is provided, with its two ends connected to the fixed base and the lifting slider, respectively, to drive the lifting slider to slide downwards.

[0018] Optionally, the platform body and the lifting slider are detachably connected via a snap-fit ​​assembly;

[0019] The platform body has a recessed slot on its side.

[0020] The snap-fit ​​assembly includes:

[0021] A rotating latch, the middle of which is hinged to the platform direct drive assembly;

[0022] A snap hook spring is located below one end of the rotating snap hook and is used to drive the other end of the rotating snap hook to rotate into the concave slot, thereby preventing the platform body from detaching upward from the lifting slider.

[0023] Optionally, the material handling robot includes a plurality of workpiece grippers that are arranged one-to-one with each of the dispensing stations, and a plurality of gripper direct drive mechanisms that are arranged one-to-one with each of the workpiece grippers.

[0024] The gripper direct drive mechanism is used to drive the corresponding workpiece gripper to reciprocate between two adjacent dispensing stations.

[0025] Optionally, the material handling robot includes a plurality of workpiece grippers that are arranged one-to-one with each of the dispensing stations, and a gripper direct drive mechanism, wherein each workpiece gripper is mounted and fixed at the drive end of the gripper direct drive mechanism.

[0026] Optionally, the distance between two adjacent dispensing stations is equal.

[0027] Optionally, the dispensing device includes a dispensing head and a dispensing drive unit that drives the dispensing head to move.

[0028] Optionally, each of the dispensing stations is equipped with a glue-wiping mechanism.

[0029] Optionally, the adhesive application mechanism includes two adhesive application blocks arranged opposite each other, and an adhesive application gripper cylinder that drives the two adhesive application blocks to move closer or further apart.

[0030] The beneficial effects of this utility model are: it provides a multi-head dispensing device.

[0031] On the one hand, multiple dispensing devices (one at each station) work simultaneously, processing different areas of the same workpiece (completing all areas during the flow). The workpiece flows through each station sequentially, completing its specific dispensing task at each station (the area the dispensing head is responsible for at that station), and finally completing all dispensing operations when flowing out. This completely changes the inefficient mode of a single dispensing head serially processing all paths.

[0032] On the other hand, the transfer robot completes the synchronous transfer of all workpieces in one action (including "loading" from the preparatory station to the first station), eliminating the waiting time for moving workpieces one by one.

[0033] Therefore, the multi-head dispensing equipment provided by this utility model can effectively solve the problem of low work efficiency caused by the single-head operation of existing dispensing devices. Attached Figure Description

[0055] See Figure 1 and Figure 2 This embodiment provides a multi-head dispensing device, including:

[0056] The workstation tray 1 has at least two dispensing stations arranged sequentially along the length of the workstation tray 1.

[0057] A plurality of adsorption platforms 2 are provided corresponding to each of the dispensing stations. Each adsorption platform 2 includes a platform body 201 for adsorbing workpieces and a platform direct drive assembly 202 for driving the adsorption platform 2 to move upward until the workpiece is removed from the station tray 1.

[0058] Material transfer robot 3 is used to synchronously transfer all workpieces on the workstation pallet 1 along the length direction of the workstation pallet 1 to the next adjacent dispensing station.

[0059] A plurality of dispensing devices 4 are provided in a one-to-one correspondence with each of the adsorption platforms 2. The dispensing devices 4 are located above the corresponding adsorption platforms 2. Different dispensing devices 4 are used to perform dispensing operations on different dispensing areas of the workpiece. All dispensing devices 4 work together to perform dispensing operations on all dispensing areas of the workpiece.

[0060] The multi-head dispensing device provided by this utility model operates as follows:

[0061] S10: Initial State / Prepared Loading:

[0062] The first workpiece, waiting to enter the production process, is placed in front of the first dispensing station (preparation station).

[0063] All dispensing stations (at least two) on the workstation tray 1 have their adsorption platforms 2 in a "lower" or "lower" state.

[0064] The material handling robot 3 is in a standby position (usually at the preparatory station or the beginning of the stroke).

[0065] The dispensing device 4 is in its initial position (it may be raised or returned to its original position).

[0066] S20: The material transfer robot 3 performs material transfer (loading & synchronous shifting starting point):

[0067] The material handling robot 3 starts and synchronously moves all the workpieces (including new workpieces in the preparatory station) on the track along the length of the track to the next adjacent dispensing station.

[0068] For example: If there are 3 dispensing stations (station A, station B, station C).

[0069] The transfer robot performs the following actions: Grab workpiece X from the preparatory station, simultaneously grab workpiece A (if any), simultaneously grab workpiece B (if any), and simultaneously grab workpiece C (if any).

[0070] Then they are moved to the next position all at once and synchronously: X moves to station A, the workpiece at station A moves to station B, the workpiece at station B moves to station C, and the workpiece at station C is removed from the track (leaving the last station, usually the unloading station or the outflow equipment).

[0071] In short: Within one action cycle, the material handling robot 3 completes the loading from "preparatory station -> first station" and the synchronous displacement of all workpieces from "first station -> second station, second station -> third station, ..., nth station -> out".

[0072] S30: Lifting and dispensing operations of adsorption platform 2:

[0073] After all workpieces arrive at their new dispensing stations, the platform direct drive components 202 of each station operate simultaneously (or almost simultaneously).

[0074] The platform direct drive component 202 drives the adsorption platform 2 (along with the workpiece it adsorbs) to move upward until the workpiece stably detaches from the workstation tray 1 (or detaches from the support / positioning contact with the workstation tray 1), reaching the working height required for dispensing.

[0075] At this time, the dispensing device 4, which is located directly above each adsorption platform 2, is activated.

[0076] Key parallel dispensing: Each dispensing device 4 is responsible for dispensing glue to a specific area (or all dispensing areas that need to be worked on at this station) of the workpiece directly below it. These "different dispensing areas" are for the same workpiece.

[0077] All dispensing devices 4 operate in parallel within the same time period. For example, the dispensing head 401 at the first station may dispense adhesive to the upper left corner of the workpiece. The dispensing head 401 at the second station may dispense adhesive to the upper right corner of the same type of workpiece (or a completely different area). The dispensing head 401 at the third station may dispense adhesive to the center area of ​​the workpiece.

[0078] Each dispensing device 4 independently completes the dispensing task of its assigned area according to a preset program. The cooperation of all dispensing devices 4 ensures that all dispensing areas of a workpiece are dispensed in sections and in parallel as it flows through each station.

[0079] After the dispensing is completed, each dispensing device 4 is raised or reset.

[0080] S40: Adsorption platform 2 descends and resets.

[0081] After all dispensing devices 4 have completed their work, the platform direct drive components 202 of all workstations will once again operate simultaneously (or in coordination).

[0082] Drive each adsorption platform 2 (along with the glued workpiece) downwards and fall back to a low position (usually back onto the workstation tray 1 or to a position ready to receive support from the workstation tray 1).

[0083] At this point, the workpiece is repositioned stably on the workstation pallet 1, ready for the next move.

[0084] S50: Repeated cycle (the transfer robot 3 moves again):

[0085] The transfer robot 3 starts again and repeats step S20: grabs the next new workpiece at the preparatory station, and at the same time grabs all the workpieces currently located at the first station, the second station, ... the nth station (i.e. the workpieces that are in the low position after being reset in step S40), and then moves them to the next station in a synchronized manner.

[0086] New workpiece -> First workstation.

[0087] Workpiece originally at the first station -> workpiece at the second station.

[0088] Workpiece originally from the second station -> third station. ...

[0090] The original workpiece at station n -> flows out (leaves the last station).

[0091] Then the equipment repeats steps S30 and S40 to synchronously lift and parallel dispensing a new batch of workpieces.

[0092] This cycle continues indefinitely.

[0093] The multi-head dispensing equipment provided in this embodiment allows multiple dispensing devices 4 (one at each station) to work simultaneously, processing different areas of the same workpiece (completing all areas during the flow). The workpiece flows sequentially through each station, completing its specific dispensing task at each station (the area handled by the dispensing head 401 at that station), and finally completing all dispensing operations upon exiting. This completely changes the inefficient mode of a single dispensing head 401 serially processing all paths.

[0094] On the other hand, the transfer robot 3 completes the synchronous transfer of all workpieces in one action (including "loading" from the preparatory station to the first station), eliminating the waiting time for moving workpieces one by one.

[0095] Therefore, the multi-head dispensing equipment provided by this utility model can effectively solve the problem of low work efficiency caused by the single-head operation of existing dispensing devices.

[0096] Optionally, in this embodiment, the number of dispensing stations is four. Of course, it can also be two, three, five, or even more.

[0097] See Figure 3 In this embodiment, the platform direct drive component 202 includes:

[0098] A fixed base 2021 is fixedly disposed relative to the workstation tray 1;

[0099] A lifting slider 2022 is slidably connected to the fixed base 2021, and the platform body 201 is located above the lifting slider 2022.

[0100] A slider direct drive mechanism 2023 is mounted on the fixed base 2021, and its drive end is connected to the lifting slider 2022 to drive the lifting slider 2022 to slide upward.

[0101] A reset spring 2024 is provided, with its two ends connected to the fixed base 2021 and the lifting slider 2022, respectively, for driving the lifting slider 2022 to slide downward.

[0102] Optionally, the slider direct drive mechanism 2023 can be a hydraulic cylinder, a motor cam assembly, or a pneumatic cylinder, etc., and this embodiment does not limit it.

[0103] The slider direct drive mechanism 2023 drives the lifting slider 2022 to slide upward, which in turn drives the platform body 201 to lift the workpiece upward; conversely, after the slider direct drive mechanism 2023 removes the driving force, the reset spring 2024 drives the lifting slider 2022 to slide downward, which in turn drives the platform body 201 to move downward and put the workpiece back on the workstation tray 1.

[0104] Furthermore, the platform body 201 and the lifting slider 2022 are detachably connected by a snap-fit ​​assembly 203;

[0105] The platform body 201 is provided with a recessed slot 2011 on its side;

[0106] The snap-fit ​​assembly 203 includes:

[0107] Rotary hook 2031, the middle part of which is hinged to the platform direct drive assembly 202;

[0108] The hook spring 2032 is located below one end of the rotating hook 2031 and is used to drive the other end of the rotating hook 2031 to rotate into the concave groove 2011 to prevent the platform body 201 from disengaging upward from the lifting slider 2022.

[0109] When the platform body 201 needs to be replaced, press down on one end of the rotating hook 2031 to disengage the other end of the rotating hook 2031 from the recessed slot 2011. The design of the buckle assembly 203 facilitates quick disassembly and assembly of the platform body 201 and improves maintenance efficiency.

[0110] As an optional implementation, in this embodiment, the material handling robot 3 includes a plurality of workpiece grippers 301 corresponding to each of the dispensing stations, and a plurality of gripper direct drive mechanisms 302 corresponding to each of the workpiece grippers 301; wherein, the gripper direct drive mechanism 302 is used to drive the corresponding workpiece gripper 301 to reciprocate between two adjacent dispensing stations. Each workpiece gripper 301 is equipped with an independent gripper direct drive mechanism 302 to achieve independent control of the gripper's lateral movement distance.

[0111] In some other embodiments, the material handling robot 3 includes a plurality of workpiece grippers 301 corresponding to each of the dispensing stations, and a gripper direct drive mechanism 302, wherein each workpiece gripper 301 is mounted and fixed at the drive end of the gripper direct drive mechanism 302. Furthermore, the distance between adjacent dispensing stations is equal. One gripper direct drive mechanism 302 drives multiple workpiece grippers 301 to move synchronously, which helps reduce the number of gripper direct drive mechanisms 302, thereby reducing material costs.

[0112] In this embodiment, see Figure 4 The dispensing device 4 includes a dispensing head 401 and a dispensing drive unit 402 that drives the dispensing head 401 to move. Optionally, the dispensing drive unit 402 can be a four-axis robot, a six-axis robot, or an XYZ three-axis module, etc., and this embodiment does not limit it.

[0113] Optionally, each of the dispensing stations is equipped with a glue-wiping mechanism 5. See also Figure 5 Furthermore, the adhesive wiping mechanism 5 includes two adhesive wiping blocks 501 arranged opposite each other, and an adhesive wiping gripper cylinder 502 that drives the two adhesive wiping blocks 501 to move closer or further apart. After the adhesive dispensing head 401 is moved between the two adhesive wiping blocks 501, the adhesive wiping gripper cylinder 502 drives the two adhesive wiping blocks 501 to move closer together, thereby wiping away the residual adhesive at the adhesive dispensing head 401.

[0114] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
