Description

Technical Field

[0001] The present disclosure relates to the field of PCB processing equipment, and more specifically, to a tool replacement device and PCB processing equipment. Background Art

[0002] At present, PCB boards tend to be highly integrated. The number of holes drilled in a single board is large and the types of holes are complex, which will inevitably require the drilling rig to be equipped with more tools. Since the current equipment mainly uses the platform to lay the tools to install the tools, the increase in the number of tools causes the size of the tool grabber to increase, resulting in an increase in the relative position between the spindle and the tool grabber. The above problems further require an increase in the Y-axis stroke of the spindle platform to ensure that the drilling rig and the tool grabber can pick up and place the tool at the same time to ensure the improvement of the tool grabber efficiency. The so-called simultaneous pick-up and place function - when the drilling rig spindle changes the tool, it is necessary to first place the old tool on the old tool holder, and the tool grabber places the new tool on the new tool holder. At this time, if the spindle and the manipulator grab the tools on the new and old tool holders at the same time, the time waste caused by the step-by-step action can be avoided, thereby improving the utilization rate of the drilling rig.

[0003] The increase in the platform's Y-axis travel will inevitably lead to an increase in the size of the drilling rig, resulting in a decrease in the number of drilling rigs placed in the same area of ​​the workshop, and even causing some models to be unable to be placed in the workshop due to their increased size. How to increase the number of tools while ensuring the simultaneous tool grabbing function and improving tool change efficiency without changing the size of the drilling rig has gradually become a problem that needs to be solved.

[0056] In order to facilitate the description of the specific structure and movement principle of the tool changing device, in the three-dimensional coordinate system, the moving direction of the PCB is defined as the Y-axis direction, the direction perpendicular to the Y-axis direction in the horizontal plane is defined as the X-axis direction, and the height direction is recorded as the Z-axis direction. Among them, the X-axis direction, the Y-axis direction, and the Z-axis direction are only for a clearer explanation and are not a limitation of the tool changing device.

[0057] In an application scenario of the present disclosure, the ejecting mechanism is installed on a support table.

[0058] When the tool needs to be replaced, the PCB processing equipment receives the tool change command, and the material picking mechanism 4 grabs the new tool on the tool disc. Then, the spindle 1 moves to above the tool detection module, and the material picking mechanism 4 places the new tool on the new tool seat; then the old tool seat 23 moves to the first position 33, at this time the spindle 1 places the old tool on the old tool seat 23, and then the old tool seat 23 moves to the second position 34, and at the same time, the spindle 1 moves to the top of the new tool seat 22 accordingly, and the spindle 1 and the material picking mechanism 4 act on the new and old tool seats 23 at the same time, respectively, to grab the new and old tools respectively; finally, the material picking mechanism 4 places the old tool on the tool disc to complete the tool replacement.

[0059] The movable old tool holder 23 is used to compensate for the increased distance between the spindle 1 and the tool gripper caused by the addition of tools. The spindle 1 and the tool gripper can be grasped simultaneously without increasing the stroke of the machining platform, thereby reducing the tool change time and improving the utilization rate.

[0060] Further, the tool detection module 21 also includes a base 25 and a tool detection assembly 24 mounted on the base 25, and the new tool holder 22 and the old tool holder 23 are respectively mounted on the base 25. The tool assembly is used to detect the tool state;

[0061] Specifically: when the tool needs to be replaced, the PCB processing equipment receives the tool change command, the material picking mechanism 4 grabs the new tool on the tool disc, and then the spindle 1 moves to above the tool detection module, and the material picking mechanism 4 places the new tool on the new tool seat; then the old tool seat 23 moves to the first position 33, and at the same time the spindle 1 performs tool detection on the old tool detection assembly 24, and then the spindle 1 places the old tool on the old tool seat 23, and then the old tool seat 23 moves to the second position 34, and at the same time the spindle 1 moves accordingly to just above the new tool seat 22, and then the spindle 1 and the material picking mechanism 4 act on the new and old tool seats 23 respectively, and grab the new and old tools respectively; finally the material picking mechanism 4 places the old tool on the tool disc to complete the tool replacement.

[0062] Furthermore, the new tool holder 22 includes a mounting seat 26 and a new tool mounting position 27 disposed on the mounting seat 26 . The new tool is installed as a constructed position for storing the new tool taken by the material taking mechanism 4 . A tool guide structure 28 is disposed on the new tool mounting position 27 .

[0063] Among them, the tool guide structure 28 on the new tool mounting position 27 can be an integral molding or a detachable connection. In this embodiment, the new tool mounting position 27 is a cylindrical guide hole with an inclined groove 32. When the tool is placed on the new tool mounting position 27 from the material picking structure, under the action of the guide groove, the tool can stand vertically on the new tool mounting position 27, so that the spindle 1 can clamp the tool more conveniently and accurately.

[0064] In addition, the tool guide structure 28 can also be a guide block or a movable push block, etc. This application only proposes the solution in this embodiment, but the tool guide structure 28 is not limited to this.

[0065] In this embodiment, the mounting seat 26 and the new tool mounting position 27 can be integrally formed or detachably connected.

[0066] Furthermore, the old tool holder 23 of the present application includes a body 29 and a first movable assembly 30, and the first movable assembly 30 is configured to drive the body 29 to move along a first direction; the first movable assembly 30 includes a first guide rail 35 and a first driving member, and the first driving member is used to drive the body 29 to move on the first guide rail 35. The body 29 is detachably mounted on the first movable assembly 30, and the body 29 includes a mounting position for placing a tool. The first driving member is configured to drive the first movable assembly 30, and the first driving member can be a motor or a cylinder. The driving portion of the first driving member is connected to the first movable assembly 30, and is used to drive the first movable assembly 30 to move on the first guide rail 35.

[0067] The main body 29 is constructed as a shell for placing old tools, and an old tool accommodating cavity is provided in the shell. The old tool accommodating cavity is used to place and store old tools used by the spindle 1. The main body 29 and the first moving assembly 30 are detachably connected. The main body 29 can be fixed on the first moving assembly 30 by different fixing methods such as buckles, bolts or pins. The first moving assembly 30 is constructed to drive the main body 29 to move along the first direction, so as to compensate for the increase in the distance between the spindle 1 and the tool grabbing mechanism caused by the addition of tools. On the basis of not increasing the stroke of the processing platform, the spindle 1 and the tool grabbing manipulator can be grasped at the same time, thereby reducing the tool changing time and improving the utilization rate. Specifically, the first moving assembly 30 includes a first guide rail 35 and a first driving member. The first driving member is used to drive the main body 29 to move on the first guide rail 35. The first driving member can be a motor or a linear cylinder.

[0068] Furthermore, the body 29 is detachably mounted on the first guide rail 35 via a slider, and the first driving member drives the slider to slide on the first guide rail 35, thereby driving the body 29 to slide on the first guide rail 35, thereby compensating for the increase in the distance between the spindle 1 and the tool gripping mechanism caused by the addition of the tool. The guide rail and slider structure are adopted, and the guide rail slider has the advantages of simple structure and easy manufacturing, and can be manufactured and assembled in a relatively short time. At the same time, the guide rail slider has the advantages of high reliability and long life, and can maintain stable performance for a long time. The guide rail slider has the advantages of high precision and high speed, and is widely used in high-speed and high-precision mechanical equipment. Ensure the distance adjustment of the two ends of the high-precision and high-stability guide rail during the tool change process.

[0069] Furthermore, a first limit block 31 is respectively provided at both ends of the first guide rail 35, and the first limit block 31 is detachably mounted at both ends of the first guide rail 35. The first limit block 31 can control the stroke and speed of the first movable assembly 30 by adjusting the position, thereby realizing precise control of the movement of the old tool disc. Improve the efficiency of cutting out old tools: The first limit block 31 can help operators quickly and accurately locate workpieces, thereby improving the efficiency of cutting out old tools. The first limit block 31 is either detachably or movably mounted at both ends of the first guide rail 35, and is used to adjust the moving distance of its slider, thereby controlling the movable distance of the main body, so that the main body can accurately align the material taking mechanism 4, thereby completing the cutting of the old tool. At the same time, the movable travel distance of the old tool holder 23 can be adjusted manually or automatically according to actual needs in different working scenarios or different tool replacement requirements.

[0070] Among them, the first limit block 31 can be fixed on both ends of the first guide rail 35 by different detachable fixing methods such as buckles, threads or screws, which is conducive to the replacement of the first limit block 31 and at the same time changes the movable stroke of its slider, thereby controlling the replaceable distance of the tool of the old tool holder 23.

[0071] Furthermore, the material-retrieving mechanism 4 is a tool-grabbing manipulator, which is constructed to grab the old tool on the old tool holder 23 and place the new tool on the new tool disc. The manipulator is responsible for grabbing and changing the tool. It is responsible for transferring the tool between the old and new tool holders 23 and the spindle 1 of the processing platform, sending the replaced tool back to the old tool holder 23, and then pushing the new tool to be used onto the spindle 1. The characteristic of this tool-changing method is that the new tool to be used and the old tool that has been used are grabbed at the same time. In other words, the tool grabbing and tool changing are carried out at the same time, so compared with other tool-changing methods, it has the characteristics of faster tool changing speed and smaller movement amplitude of each mechanical component.

[0072] Furthermore, the material taking mechanism 4 includes a fine adjustment mechanism 41 and a grabbing head 42 mounted on the fine adjustment mechanism 41, and the fine adjustment mechanism 41 is configured to drive the grabbing head 42 to move along the third direction. The fine adjustment mechanism 41 is used to adjust the position of the grabbing head 42, and can finely adjust the position of the grabbing head 42 according to the actual situation and the specific positions of the new and old tool holders 23, so that the grabbing head 42 is in a positional relationship with the new and old tool holders 23, so that the tool change of the grabbing head 42 is more accurate and efficient.

[0073] Furthermore, the fine-tuning mechanism 41 includes a second driving member 43 and a second moving mechanism 44, and the second driving member 43 drives the grabbing head 42 to move along the third direction on the second guide rail 45. The second moving mechanism 44 is configured to drive the grabbing head 42 to move along the third direction, thereby compensating for the position difference between the tool and the new and old tool discs caused by the addition of the grabbing head 42. Without adjusting the distance to the tool holder, the tool grabbing manipulator can accurately grab the tool, reduce the tool change time, and improve the utilization rate. The second driving member 43 can be a motor or a linear cylinder.

[0074] Furthermore, a second limit block 48 is provided at both ends of the second guide rail 45. The second limit block 48 can control the stroke and speed of its second movable component by adjusting the position, thereby realizing precise control of the movement of the grab head 42. Improve tool blanking efficiency: The second limit block 48 can help the operator to quickly and accurately locate the workpiece, thereby improving the efficiency of old tool blanking. The second limit block 48 is either detachable or movably installed at both ends of the second guide rail 45, and is used to adjust the moving distance of its second movable component, thereby controlling the movable distance of the grab head 42, so that the grab head 42 can accurately align the new and old tool discs, thereby completing the blanking of the new and old tools. At the same time, the movable travel distance of the grab head 42 can be adjusted manually or automatically according to actual needs in different working scenarios or different tool replacement requirements.

[0075] Specifically: In this embodiment: when the device receives a tool change command, the tool grabbing manipulator moves to grab the new tool on the tool disc, moves to the top of the new tool holder, and then the new tool is accurately installed on the installation position of the new tool holder 22 after being guided by the guide structure 28;

[0076] Combination Figure 1-4

[0077] Then the spindle 1 moves to the tool inspection assembly 24, which blocks light through the drill bit, tests the tool diameter, and checks the tool information, while the old tool holder 23 moves to the first position 33;

[0078] The spindle 1 grabs the old tool and moves it to the top of the old tool holder 23, and then places the old tool on the old tool holder 23; then the old tool holder 23 moves to the second position 34 (: the spindle 1 and the tool grabbing manipulator simultaneously move to the new and old tool holders 23, respectively, grab the new and old tools at the same time, and finally the tool grabbing manipulator places the old tool on the tool disk, completing the tool changing action, and the spindle 1 processing starts.

[0079] The second position 34 in the present application is the extended position of the old tool holder 23, that is, the position difference between the spindle 1 and the tool gripper mechanism. The purpose of this embodiment is to compensate for the increased distance between the spindle 1 and the tool gripper mechanism caused by adding tools without increasing the stroke of the machining platform.

[0080] In another embodiment, in the embodiment: when the device receives a tool change command, the tool grabbing manipulator moves to grab the new tool on the tool disc, moves to the top of the new tool holder, and then the new tool is accurately installed on the installation position of the new tool holder 22 after being guided by the guide structure 28;

[0081] Then the spindle 1 moves to the tool detection assembly 24 , which blocks light through the drill bit, tests the tool diameter, and verifies the tool information. Meanwhile, the old tool holder 23 moves to the first position 33 .

[0082] Spindle 1 grabs the old tool and moves it to the top of the old tool holder 23, and then places the old tool on the old tool holder 23; then spindle 1 and the tool grabbing robot move to the new and old tool holders 23 respectively at the same time, grab the new and old tools respectively at the same time, and finally the tool grabbing robot places the old tool on the tool disc, completing the tool changing action, and spindle 1 processing starts.

[0083] The first position 33 in the present application is the original position of the old tool. When the distance between the spindle 1 and the tool gripping mechanism of the present application is sufficient, the present application can realize the replacement of the tool without moving the old tool holder 23 .

[0084] In another embodiment, in combination Figure 4 The fine adjustment mechanism 41 is used to compensate for the problem of the distance between the spindle 1 and the tool gripping mechanism being increased due to the tool without increasing the stroke of the machining platform.

[0085] First, the equipment receives a tool change command, and the tool grabber moves the grabber head 42 to the third position 46 through the fine-tuning mechanism 41, grabs the tool on the tool disk, and places the new tool on the tool holder. Then, the spindle 1 moves with the tool to the tool inspection component 24 to detect the tool, and then places the tool on the old tool holder 23; the tool grabber moves the grabber head 42 to the initial position 47 through the fine-tuning mechanism 41, and the spindle 1 and the tool grabber act on the new and old tool holders 23 at the same time to grab the new and old tools; finally, the tool grabber adjusts the position of the tool grabber according to the tool placement position, places the old tool on the tool disk, completes the tool change action, and spindle 1 processing begins.
