Detailed Description

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. Preferred embodiments of the present utility model will now be described in detail with reference to the accompanying drawings.

The embodiment of the present utility model provides a drilling apparatus 1000, as shown in fig. 1 to 3, the drilling apparatus 1000 includes a carrying table 110, a visual recognition mechanism 120, and a lifting driving mechanism 130. The plummer 110 is used for placing the work piece 8000 that waits to process, and visual recognition mechanism 120 sets up in plummer 110 top, and visual recognition mechanism includes camera 121 and abutment 122, and camera 121 is used for shooing the work piece 8000 that waits to process, and abutment 122 is located the bottom of camera 121. The lifting driving mechanism 130 is connected to the visual identifying mechanism 120, and the lifting driving mechanism 130 is used for driving the visual identifying mechanism 120 to move relative to the carrying table 110, so that the abutting piece 122 can abut against the workpiece 8000 to be processed.

The usage flow of the drilling apparatus 1000 of the present embodiment is as follows: firstly, placing a workpiece 8000 to be processed on a bearing table 110; then, the visual identification mechanism 120 is driven to descend by the lifting driving mechanism 130 until the abutting piece 122 of the visual identification mechanism 120 abuts against the bearing table 110; the drilling position is then photographed by a camera 121, and the deviation is calculated and compensated for hole machining.

Specifically, since the lifting driving mechanism 130 drives the visual recognition mechanism 120 to move integrally, the distance between the camera 121 and the abutment 122 is always kept constant, and since the camera 121 drives the abutment 122 to abut against the workpiece 8000 to be processed before shooting, the distance between the camera 121 and the workpiece 8000 to be processed is consistent as long as the abutment 122 abuts against the workpiece 8000 to be processed regardless of the thickness of the workpiece 8000 to be processed. Therefore, the embodiment can realize automatic focusing without manually adjusting the height of the visual recognition mechanism 120 when workpieces with different thicknesses are replaced, so that the visual recognition mechanism is very convenient to use and has better experience of operators.

Referring to fig. 2, in a specific embodiment, a plurality of abutments 122 are provided, and projections of the plurality of abutments 122 in the gravitational direction (Z direction in fig. 2) encircle projections of the camera 121 in the gravitational direction.

If the workpiece 8000 to be processed is deformed and tilted, the visual recognition mechanism 120 cannot accurately calculate the deviation and compensate the deviation. In order to solve the technical problem, the plurality of the abutting pieces 122 are provided, and the projection of the plurality of the abutting pieces 122 in the gravity direction surrounds the projection of the camera 121 in the gravity direction, and because the camera 121 is opposite to the drilling position of the workpiece 8000 to be processed, the plurality of the abutting pieces 122 in the embodiment surround the drilling position of the workpiece 8000 to be processed when in use, and the accuracy of compensation is improved by firstly holding the surrounding of the drilling position, then calculating the deviation and compensating.

In a specific embodiment, the drilling apparatus 1000 further includes a drilling mechanism 140, where the drilling mechanism 140 is disposed above the carrier 110 for performing hole machining on the workpiece 8000 to be machined. A pressing mechanism (not shown) is disposed above the carrying table 110, and the pressing mechanism is used for pressing the workpiece 8000 to be processed onto the carrying table 110 before the drilling mechanism 140 performs hole processing on the workpiece 8000 to be processed.

Specifically, if there is a possibility that the workpiece 8000 to be processed is deformed and tilted, the accuracy of drilling is relatively poor if the workpiece 8000 to be processed is subjected to hole processing on the basis of deformation, so as to avoid influencing the actual processing quality due to the deformation and tilting of the workpiece 8000 to be processed, the drilling device 1000 of the embodiment is provided with a pressing mechanism, and the pressing mechanism can press the workpiece 8000 to be processed on the bearing table 110 before the drilling mechanism 140 performs hole processing on the workpiece 8000 to be processed, so that the workpiece 8000 to be processed cannot finish hole processing in a state of deformation and tilting, and the processing quality is ensured.

Illustratively, the pressing mechanism includes a pressing plate (not shown in the drawings) and a pressing cylinder (not shown in the drawings) that can drive the pressing plate to press down so as to press the workpiece 8000 to be processed. The platen is provided with a light-transmitting opening (not shown) so that the drilling mechanism 140 can perform hole machining on the workpiece 8000 through the light-transmitting opening.

It should be noted that the drilling apparatus 1000 of the present embodiment is mainly used for performing hole processing on the multilayer circuit board 9000. In order to improve signal transmission performance, the prior art performs back drilling on the multilayer circuit board 9000 to reduce the length of the unnecessary copper pillars, referring to fig. 4, the multilayer circuit board 9000 needs to perform first drilling on one surface of the multilayer circuit board 9000 to process a first drilling 910, then performing processes such as electroplating, and finally performing back drilling on the other surface of the multilayer circuit board 9000 to process a back drilling 920 to remove an unnecessary hole wall copper layer 930.

Because the multilayer circuit board 9000 needs to be clamped for the second time, and the multilayer circuit board 9000 is easy to deform after processes such as electroplating, the drilling equipment 1000 of the embodiment can utilize the visual recognition mechanism 120 to compensate, utilize the plurality of abutting pieces 122 to improve the compensation accuracy, and utilize the pressing mechanism to improve the processing accuracy, and can effectively guarantee the processing quality, the multilayer circuit board 9000 needing back drilling is very suitable for drilling by using the drilling equipment 1000 of the embodiment.

Of course, it is understood that the drilling apparatus 1000 of the present embodiment may also be used to perform hole machining on other workpieces.

Referring to fig. 1, in an embodiment, the drilling apparatus 1000 further includes a horizontal driving mechanism 150, where the horizontal driving mechanism 150 includes a first linear driving assembly (not shown in the drawing), and the first linear driving assembly is connected to the carrying stage 110 or the visual recognition mechanism 120 to drive the carrying stage 110 or the visual recognition mechanism 120 to move along a first direction.

Specifically, there may be a plurality of holes 810 to be machined in one workpiece 8000 to be machined. In order to identify a plurality of holes 810 to be machined by using one visual identification mechanism 120, the relative positions of the visual identification mechanism 120 and the workpiece 8000 to be machined need to be adjusted so that the visual identification mechanism 120 can correspond to different holes 810 to be machined. To achieve this effect, the drilling apparatus 1000 of the present embodiment is provided with a horizontal driving mechanism 150, where the horizontal driving mechanism 150 includes a first linear driving component, and the first linear driving component is connected to the carrying table 110 or the visual recognition mechanism 120 to drive the carrying table 110 or the visual recognition mechanism 120 to move along a first direction, so as to adjust the relative position of the visual recognition mechanism 120 and the workpiece 8000 to be processed.

Referring to fig. 1, in a specific embodiment, the first linear driving assembly is connected to the carrying platform 110, and the horizontal driving mechanism 150 further includes a second linear driving assembly 151, where the second linear driving assembly 151 is connected to the visual recognition mechanism 120 to drive the visual recognition mechanism 120 to move along a second direction (X direction in fig. 1) perpendicular to the first direction.

If the visual recognition mechanism 120 can only perform one-dimensional motion with respect to the workpiece 8000 to be processed, the plurality of hole sites 810 to be processed can only be distributed on the same straight line, and if the plurality of hole sites 810 to be processed are two-dimensionally distributed, the visual recognition mechanism 120 cannot be used for recognizing all the hole sites 810 to be processed, so that the versatility of the drilling device 1000 is poor. In order to solve this problem, the horizontal driving mechanism 150 of the present embodiment includes a first linear driving assembly and a second linear driving assembly 151, and the first linear driving assembly and the second linear driving assembly 151 can respectively drive the carrying platform 110 and the visual recognition mechanism 120 to move in two directions (a first direction and a second direction) perpendicular to each other, so that the visual recognition mechanism 120 can recognize a plurality of holes 810 to be processed in a two-dimensional division.

In one embodiment, the abutment 122 is a universal wheel.

It should be noted that, when the workpiece 8000 has a plurality of holes 810 to be machined, the visual recognition mechanism 120 needs to move relative to the workpiece 8000 after recognizing the first hole 810, if the abutment 122 cannot rotate, a large sliding friction force is generated between the abutment 122 and the workpiece to be machined, which easily causes damage to the abutment 122 or the workpiece 8000 to be machined. If it is desired to avoid the contact between the abutment 122 and the workpiece 8000 to be processed, the visual recognition mechanism 120 needs to be driven to rise by the lifting driving mechanism 130 after the first hole site 810 is recognized, and the visual recognition mechanism 120 needs to be driven to fall by the lifting driving mechanism 130 after the positions of the visual recognition mechanism 120 and the workpiece 8000 to be processed are adjusted.

In order to ensure the machining efficiency on the premise of avoiding damage to the abutting piece 122 and the workpiece 8000 to be machined, the abutting piece 122 in this embodiment is a universal wheel. With this arrangement, the friction between the abutment 122 and the workpiece to be machined becomes rolling friction, thereby effectively preventing the abutment 122 or the workpiece 8000 to be machined from being damaged.

Referring to fig. 1, in one embodiment, the visual recognition mechanism 120 is provided with at least two, and the plurality of visual recognition mechanisms 120 are disposed at intervals in the second direction so as to process a plurality of workpieces 8000 to be processed using one drilling apparatus 1000.

Referring to fig. 2, in an embodiment, the visual recognition mechanism 120 further includes a light supplement lamp 123, and the light supplement lamp 123 is disposed above the carrying stage 110 and is disposed toward the carrying stage 110.

Specifically, the light-compensating lamp 123 can compensate light toward the shooting position of the camera 121, so as to improve the brightness of the shot position, further improve the shooting effect of the camera 121, improve the accuracy of recognition, and further improve the processing quality.

Referring to fig. 2, in order to improve the light supplementing effect, in a specific embodiment, the light supplementing lamp 123 is an annular light supplementing lamp 123, and a projection of the light supplementing lamp 123 in the gravity direction surrounds a projection of the camera 121 in the gravity direction.

Referring to fig. 5 and 6, in an embodiment, the visual recognition mechanism 120 further includes a mounting base 124, the camera 121 and the abutment 122 are both disposed on the mounting base 124, the mounting base 124 has a clamping groove 1241 disposed in a horizontal direction, the drilling device 1000 further includes a blocking mechanism 160, the blocking mechanism 160 includes a third linear driving member 161 and a clamping block 162, the third linear driving member 161 is fixedly disposed on one side of the clamping groove 1241 and is connected to the clamping block 162, and the third linear driving member 161 is used for driving the clamping block 162 to move relative to the clamping groove 1241 so that the clamping block 162 can be inserted into or separated from the clamping groove 1241.

Specifically, since the clamping groove 1241 on the mounting seat 124 is disposed along the horizontal direction, when the clamping block 162 is inserted into the clamping groove 1241, the groove wall at the bottom of the clamping groove 1241 will cooperate with the clamping block 162 to limit the movement of the mounting seat 124 toward the carrying platform 110. Because the camera 121 and the abutting piece 122 are disposed on the mounting base 124, the camera 121 and the abutting piece 122 cannot move toward the carrying platform 110 when the clamping block 162 is inserted into the clamping groove 1241. By the arrangement, the situation that the visual recognition mechanism 120 suddenly breaks down and moves downwards when the drilling mechanism 140 drills the workpiece 8000 to be processed can be avoided, and the situation that the workpiece 8000 to be processed is damaged can be effectively avoided.

It should be understood that the foregoing embodiments are merely illustrative of the technical solutions of the present utility model, and not limiting thereof, and that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art; all such modifications and substitutions are intended to be included within the scope of this disclosure as defined in the following claims.
