Description

Technical Field

[0001] This invention relates to the field of automated processing equipment control technology, specifically to a control method and drilling machine based on grouped drilling. Background Technology

[0002] A rhinestone applicator is a device that automatically attaches small diamonds, rhinestones, or sequins to the surface of workpieces (such as mobile phone cases, decorations, handicrafts, etc.), and is widely used in the fashion and decoration industry. Traditional single-head rhinestone applicators are inefficient and cannot meet the needs of mass production.

[0003] Existing manufacturers have developed a type of point drilling machine with multiple drill bits connected in parallel. This type of equipment typically mounts multiple drill bits on a single machine head and uses a moving platform for positioning, enabling simultaneous pick-up and drop-off of the drill bits. However, this existing "simultaneous pick-up and drop-off" point drilling machine has the following problems in use:

[0004] When the pattern points on the workpiece that need to be drilled are irregularly distributed, or different points require different types of drills (such as color and size), all drill bits must be moved directly above the same batch of points in order to work simultaneously. If the points are scattered or of different types, multiple overall movements and batch operations are required, which reduces efficiency and makes programming complex and inflexible. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the shortcomings of the existing technology by providing a control method and a drilling machine that can set up multiple drill bits to operate in parallel, flexibly adapt to complex point distribution, and significantly improve drilling efficiency while ensuring processing accuracy.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] On one hand, the present invention provides a control method based on grouped point drilling, comprising the following steps:

[0008] Step S1) Configure multiple point drill bits, divide all point drill bits into n drill bit groups, where n≥2, and preset a corresponding set of processing points for each drill bit group; Step S2) Send control signals to all point drill bits to control each point drill bit to synchronously perform the drill picking action;

[0009] Step S3) Perform the drill release process sequentially on n drill bit sets according to a preset order; for the current target drill bit set, the drill release process includes:

[0010] Step S31) Move the current target drill bit set to its corresponding processing point set;

[0011] Step S32) Control the synchronous extension of the drill bits in the current target drill bit group to perform the drilling process. At this time, the other drill bit groups are in standby mode. Step S33) After confirming that the current target drill bit group has been processed, switch to the next drill bit group as the new current target drill bit group, and repeat steps S31)-S32) until all drill bit groups have been processed.

[0068] In this embodiment 1, the vacuum control valve group 51 includes two vacuum valve groups, each containing six valves, for a total of twelve valves. The two vacuum valve groups are connected to the suction nozzles 3211 of the twelve point drill bits 321 one by one through independent air pipes, and independently control the vacuum passage of the suction nozzles 3211 of the twelve point drill bits 321, thereby achieving independent and precise control of the vacuum suction force of each suction nozzle 3211.

[0069] There are two telescopic solenoid valves, which together form a telescopic control valve group, namely telescopic solenoid valve 1 and telescopic solenoid valve 2. Each telescopic control valve group is used to control the synchronous operation of all telescopic cylinders 3212 in a set of drill bits 321. Specifically, telescopic solenoid valve 1 controls the telescopic cylinders 3212 of all odd-numbered drill bits 321 (first, third, fifth, seventh, ninth, and eleventh) through air flow; while telescopic solenoid valve 2 controls the telescopic cylinders 3212 of all even-numbered drill bits 321 (second, fourth, sixth, eighth, tenth, and twelfth).

[0070] In this embodiment 1, the air circuit control system 5 further includes a dual-stage filter 54, a first main air supply circuit, a second main air supply circuit, a vacuum control air circuit, a dispensing material pressure air circuit, a drill disc solenoid valve, and a drill disc control air circuit. The dual-stage filter 54 has an inlet end and an outlet end for connecting to an external air source; the inlets of both the first and second main air supply circuits are connected to the outlet end of the dual-stage filter 54; one end of the vacuum control air circuit is connected to the vacuum control valve assembly 51, and one end of the dispensing material pressure air circuit is connected to... The dispensing head 322 is connected, and one end of the drill disk control air circuit is connected to the drill disk solenoid valve; the first main air supply circuit is connected to the vacuum control air circuit where the vacuum control valve group 51 is located and the dispensing material pressure air circuit of the dispensing head 322 respectively. The first main air supply circuit is configured to provide air source to the vacuum control valve group 51 and the dispensing head 322; the second main air supply circuit is connected to the telescopic solenoid valve and the drill disk control air circuit where the drill disk solenoid valve is located respectively. The second main air supply circuit is configured to provide air source to the telescopic solenoid valve and the drill disk solenoid valve.

[0071] The air circuit control system 5 also includes a first Y-type tee 55, a second Y-type tee 56, a third Y-type tee 57, a fourth Y-type tee 58, a Y-type four-way valve, a vacuum pressure regulating valve, a material pressure regulating valve, a fifth Y-type tee 59, and a drill disk control air circuit. The first Y-type tee 55 is located between the inlet end of the first main air supply circuit and the second main air supply circuit and the dual-stage filter 54. The outlet end of the dual-stage filter 54 is connected to the first main air supply circuit and the second main air supply circuit through the first Y-type tee 55. The first main air supply circuit is connected to the vacuum control air circuit and the dispensing material pressure air circuit through the second Y-type tee 56. The vacuum pressure regulating valve is located on the vacuum control air circuit, and the material pressure regulating valve is located on the material pressure control air circuit. The external air source first connects to a dual-stage filter 54 (which includes precision filtration and pressure regulation functions), outputting clean and stable compressed air. The clean and stable compressed air is divided into the first main air supply circuit and the second main air supply circuit through the first Y-type tee 55, wherein:

[0072] The gas in the first main gas supply path is first divided into two branches, a vacuum control gas path and a material pressure control gas path, through the second Y-type tee 56. The gas delivered by the vacuum control gas path is distributed to the air inlets of the two vacuum control valve groups 51 through the vacuum pressure regulating valve and the third Y-type tee 57, providing a vacuum negative pressure for all nozzles 3211. The gas delivered by the material pressure control gas path is distributed to the MAC solenoid valve 53 and the material pressure digital display 8 after passing through the material pressure regulating valve. The gas delivered by the material pressure control gas path is distributed to the syringes 3221 of the dispensing heads 322 of several parallel gun dual-point drilling module groups 32 after passing through the MAC solenoid valve 53 and the fourth Y-type tee 58, providing a constant material supply air pressure for the syringes 3221 of each dispensing head 322.

[0073] The second main air supply circuit (action control air circuit): The gas in the second main air supply circuit is split into two paths through a fifth Y-type tee 59. One path is the telescopic manifold control air circuit, and the other path is the drill table control air circuit. The telescopic manifold control air circuit is connected to two telescopic solenoid valves, namely telescopic solenoid valve 1 and telescopic solenoid valve 2. These two telescopic solenoid valves are used to control the extension and retraction of the telescopic cylinder 3212. The output port of telescopic solenoid valve 1 is connected in parallel to the telescopic cylinder 3212 of drill bits 321 at points 1, 3, 5, 7, 9, and 11 (all odd-numbered points) through a manifold. Similarly, telescopic solenoid valve 2 controls the telescopic cylinder 3212 of drill bits 321 at all even-numbered points. The second main air supply circuit is connected to the drill table air circuit where the drill table solenoid valve is located through the fifth Y-type tee 59, providing an air source for the auxiliary cylinders such as the drill table telescopic mechanism on the worktable 1.

[0074] The first main air supply path of this invention is a vacuum control air path, and the second main air supply path is an action control air path. The first main air supply path provides an air source to the vacuum control valve group 51 to generate a vacuum, and optionally provides an air source to the dispensing material pressure air path of the dispensing head 322 to form a pushing pressure. The second main air supply path provides a driving air source to the telescopic control valve to provide power for the lifting and lowering of the drill bit 321. It can also optionally provide an air source to the drill plate solenoid valve on the worktable 1 to control the two sets of drill plate telescopic devices 7 on the double-layer drill plate placement module 6.

[0075] The control process of the air circuit control system 5 of the 1-point drilling machine of the present invention includes the following steps:

[0076] Gas source treatment: The external factory gas source is first connected to the dual-stage filter 54, and the gas is filtered through the dual-stage filter 54 to obtain purified gas;

[0077] Gas diversion: The purified gas exits from the outlet of the dual-stage filter 54, and is divided into the first main gas supply path and the second main gas supply path via the first Y-type tee 55.

[0078] The first main air supply circuit is divided into two circuits: a vacuum control air circuit and an adhesive dispensing air circuit, through a second Y-shaped tee 56.

[0079] Vacuum control gas path: Connected to the air inlet of vacuum control valve group 51 (i.e., vacuum valve group 1 and vacuum valve group 2). Each vacuum valve group contains six independent valves, each valve being directly connected to a point drill bit 3211 suction nozzle 3211 via an independent φ4 or φ6 air pipe. Taking one group as an example, the six valves of vacuum valve group 1 control the suction nozzles 3211 of the first, third, fifth, seventh, ninth, and eleventh point drill bits 321, respectively; the six valves of vacuum valve group 2 control the suction nozzles 3211 of the second, fourth, sixth, eighth, tenth, and twelfth point drill bits 321, respectively. The exhaust ports of the two vacuum valve groups are connected to a vacuum generator or vacuum pump to generate suction.

[0080] Dispensing air circuit: Provides constant pressure to the six syringes 3221 of the six dispensing heads 322, pushing the glue out.

[0081] The second main air supply line (action control air line): is divided into two lines via a fifth Y-type tee 59. One line is for telescopic convergence, and the other is for drill disk control air line, wherein:

[0082] Telescopic manifold control air circuit: A manifold is connected, with its two outlets connected to the inlets of telescopic solenoid valves 1 and 2, respectively. The outlet of telescopic solenoid valve 1 is connected in parallel via an air pipe to the telescopic cylinders 3212 of drill bits 321 at points 1, 3, 5, 7, 9, and 11. Similarly, telescopic solenoid valve 2 controls cylinders 2, 4, 6, 8, 11, and 12. The solenoid valves control the extension and retraction of the cylinders.

[0083] Drill board control air circuit: Drill board solenoid valve connected to the control cylinder 71 for extending and retracting the drill board.

[0084] Each drill bit 321 of this invention has a suction nozzle 3211 corresponding to an independent vacuum valve group. This allows for precise control of the timing of each drill bit 321 disengaging from the vacuum during drill release, avoiding mutual interference and ensuring that the drill material is released only at the moment the telescopic cylinder 3212 is pressed down. This precise control of drill release prevents the drill material from falling prematurely. The twelve telescopic cylinders 3212 are divided into two groups according to the odd and even numbers of the drill bit sequence, and are centrally controlled by two telescopic solenoid valves. This greatly simplifies the air piping and electrical wiring, reduces costs, and enables the two groups of drill bits to operate in a time-sharing manner. The group pressing down reduces the instantaneous air consumption and mechanical impact, making the movement smoother.

[0085] like Figure 1 As shown, this embodiment 1 provides a control method based on grouped spot drilling, which includes the following steps:

[0086] Step S1 (Initialization Grouping): The operator divides the total 12 drill bits 321 into two drill bit groups through the interface of the controller 2. For example, the "left" drill bit (first drill bit 321) of all the parallel gun dual-point drill module groups 32 is defined as the first drill bit group, and all the "right" drill bits (second drill bit 321) are defined as the second drill bit group. Then, for several points on the workpiece to be processed (16 points in this embodiment 1), the coordinates of 8 points can be assigned to the first group according to the point spacing and drill bit type, and the coordinates of the other 8 points can be assigned to the second group.

[0087] Step S2 (simultaneous drill retrieval): Controller 2 controls the three-axis moving device 4 to move the entire dual-position gun device 3 above the drill plate 63 of the drill plate placement module. Then, controller 2 simultaneously sends a signal to the air circuit control system 5, causing the air circuit control system 5 to open the vacuum passage of the suction nozzles 3211 of all 16 point drill bits 321 and control the telescopic cylinders 3212 of all point drill bits 321 to extend synchronously, so that all point drill bits 321 simultaneously absorb the drill material, completing the one-time drill retrieval. The efficiency of this drill retrieval process is 8 times that of single-head drill retrieval.

[0088] Step S3 (Grouping and sequential drilling):

[0089] Step S31 (Release of Drill Bit Group 1): Controller 2 controls the movement of the three-axis moving device 4 to precisely align the drill bit group 1 (i.e., the point drill bit 321 on the "left" side of the six sets of parallel gun double-position drilling mold group 32) with drill material adsorbed on the parallel gun double-position device 3 with its assigned six processing points. The air circuit control system 5 controls the valve action of the telescopic solenoid valve 1 in the telescopic solenoid valve group 52 to drive the six telescopic cylinders 3212 of the first drill bit group to extend and retract synchronously, completing the release of drill material from the first drill bit group. At the same time, it controls the telescopic solenoid valve 2 in the telescopic solenoid valve group 52 to close, so that the second drill bit group does not move at this stage.

[0090] Step S32 (Release of the second drill bit group): After the release of the first drill bit group is completed, the controller 2 controls the three-axis moving device 4 to move and precisely align the first drill bit group (i.e., the point drill bit 321 on the "right side" of the six sets of parallel gun double-position drilling mold group 32) with drill material adsorbed on the parallel gun double-position device 3 with its assigned six processing points. The air circuit control system 5 controls the valve action of the telescopic solenoid valve 2 in the telescopic solenoid valve group 52, driving the six telescopic cylinders 3212 of the second drill bit group to extend and retract synchronously, completing the release of drill material for the second drill bit group.

[0091] Step S4 (Cycle): After the second drill bit group is released, the Z-axis lifting device 43 rises and the gun double-position device 3 moves back to the position of the double-layer drill table placement module 6. The above synchronous drill retrieval and group release operations are repeated to carry out the next round of drill retrieval and spot drilling operations.

[0092] The control method of this invention enables the drilling of all points in a flexible and orderly manner by grouping and releasing drill bits after a single drilling operation, based on the actual point distribution.

[0093] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
