It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element. The terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description, but do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed in a specific orientation, and operate, and thus are not to be construed as limiting the present application, and the specific meanings of the above terms may be understood by those skilled in the art according to specific situations. The terms "first", "second" and "first" are used merely for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "plurality" is two or more unless specifically limited otherwise.

Referring to fig. 1 and 9, an exemplary embodiment of a disassembling and assembling apparatus 100 for separating a first workpiece 200 and a second workpiece 300 is provided. A plurality of through inserting holes 201 are formed in the first workpiece 200 at intervals, and a second workpiece 300 is inserted into each inserting hole 201. Optionally, in this embodiment, the second workpiece 300 is a drill point for drilling a PCB, and the first workpiece 200 is a magazine for placing a drill point; one end of the plug-in hole 201 is an opening, the other end is provided with an annular limiting surface, and a through hole is formed in the center of the annular limiting surface; the bottom of the drill point is placed into the plug hole 201 from the opening and abuts against the annular limiting surface, and the tip of the drill point is exposed out of the plug hole 201.

It can be understood that the drill point for drilling the PCB reaches the limit of the life span after the PCB board is processed, and cannot be used any more due to the wear of the tip portion. For secondary use, the drill point needs to be transferred from the special needle box of the drilling machine to a magazine for regrinding or other treatment. At present, due to the lack of corresponding auxiliary equipment, worn drill bits can be transferred from a needle box to a magazine only by a manual operation mode, the process is complicated, and the drill bits are usually pulled out from the needle box one by one manually and then are inserted into the magazine in sequence. However, transferring the drill point in a manually operated manner has the following disadvantages: firstly, manual operation has instability, not only has lower working efficiency, but also is easy to cause drill point damage, thereby improving the use cost of the drilling machine. Secondly, because the needle point of the drill point is sharp, the potential safety hazard that the drill point pricks the hand still exists in the manual needle pulling. The preferred means for mechanically separating the drill bit from the magazine can be divided into two main categories: firstly, fixing a needle box, and pushing out a drill needle by a structure; secondly, the drill needle is propped by a structure, and the needle box is pulled out after being clamped tightly. The present embodiment adopts the second mode.

Referring to fig. 1, 2 and 7, the dismounting device 100 includes a pulling structure 10 and a thrust structure 20 disposed opposite to each other. The drawing structure 10 comprises a lifting plate 11 and a driving mechanism 13 connected with the lifting plate 11, and the driving mechanism 13 can drive the lifting plate 11 to reciprocate along a preset track; the thrust structure 20 includes a thrust plate 21 fixedly disposed with respect to the elevating plate 11 and a thrust pin 22 having one end connected to the thrust plate 21. The surface of the lifting plate 11, which faces away from the thrust structure 20, is detachably connected with a first workpiece 200, and a through avoidance hole 1121 is formed in the position, corresponding to the insertion hole 201, of the lifting plate 11; the other end of the thrust pin 22 extends toward the lifting plate 11 and an extension line thereof passes through the insertion hole 201. The driving mechanism 13 drives the lifting plate 11 and the first workpiece 200 to move towards the thrust plate 21 by a predetermined distance, so that the other end of the thrust pin 22 extends into the insertion hole 201 through the relief hole 1121 to abut against the second workpiece 300 and limit the second workpiece 300 to move further.

It is understood that the lifting plate 11 moves toward the thrust plate 21 under the action of the driving mechanism 13, and at the same time, the first workpiece 200 and the second workpiece 300 also move toward the thrust plate 21 under the traction of the lifting plate 11; the second workpiece 300 moves a predetermined distance along with the first workpiece 200 and then abuts against the corresponding thimble; thereafter, the first workpiece 200 continues to move towards the direction of the thrust plate 21 under the traction of the lifting plate 11, and the second workpiece 300 cannot continue to move along with the first workpiece 200 under the blocking action of the ejector pins, so that the second workpiece 300 gradually disengages from the corresponding plug hole 201 on the first workpiece 200; each second workpiece 300 is separated from the first workpiece 200 in the manner described above. In summary, the technical problem of how to dismantle the drill point from the needle box and improve the dismantlement efficiency of a plurality of drill points has been solved to this application embodiment.

Referring to fig. 7 and 9, optionally, in the present embodiment, ten or more plugging holes 201 are formed at intervals on the first workpiece 200, and the plugging holes 201 are linearly arranged at equal intervals; at least ten of the insertion holes are inserted with second workpieces 300.

Referring to fig. 3, 5 and 7, optionally, in the present embodiment, the drawing structure 10 further includes a plurality of drawing blocks 12. Wherein, a plurality of drawing blocks 12 are arranged at intervals at one end of the lifting plate 11 back to the thrust plate 21, and a first workpiece 200 is clamped between any two adjacent drawing blocks 12.

It can be understood that, in the present embodiment, the plurality of first workpieces 200 are detachably attached to the lifting plate 11, and thus the plurality of first workpieces 200 can be separated from the corresponding plurality of second workpieces 300 at the same time.

Referring to fig. 5 and 7, alternatively, in the present embodiment, six drawing blocks 12 are provided at intervals; accordingly, five first works 200 are detachably attached to the lifting plate 11.

It is understood that, in the present embodiment, the disassembling and assembling apparatus 100 can disassemble fifty second works 300 from five first works 200 at a time.

It can be understood that, when the second workpiece 300 is a drill point and the first workpiece 200 is a magazine, fifty drill points need to be synchronously ejected from the magazine in a whole magazine, which satisfies the requirement of matching the designed fixture with the contour structure of the magazine and the requirement of consistent positioning of the ejector pin mounting position of the ejection magazine and the drill point position. In addition, the problem of damage such as tip breakage, shortage and the like during the process of withdrawing the box of the drill bit is also considered.

Referring to fig. 5 and fig. 7, optionally, in the present embodiment, the opposite surfaces of any two adjacent drawing blocks 12 are respectively provided with a clamping groove 121, two sides of the first workpiece 200 are respectively provided with a protrusion 202 adapted to the clamping groove 121, and the protrusion 202 is inserted into the corresponding clamping groove 121.

Referring to fig. 5 and 7, it can be understood that the first workpiece 200 can be detachably connected to the lifting plate 11 by inserting the protrusions 202 on the two sides of the first workpiece 200 into the corresponding clamping grooves 121 on any two adjacent pulling blocks 12.

Referring to fig. 5 and 7, optionally, the cross section of each avoiding hole is a long strip, and an avoiding hole is formed between two adjacent drawing blocks 12; the projections of the inserting holes 201 between the same two drawing blocks 12 towards the lifting plate 11 all fall into the corresponding avoiding holes.

Referring to fig. 4 and fig. 5, optionally, in the present embodiment, each of the avoiding holes 1121 is a cylindrical through hole, and a diameter of a cross section of the avoiding hole is slightly larger than a diameter of a corresponding position of the thrust pin 22.

It will be appreciated that the use of a plurality of cylindrical relief holes 1121 of smaller cross-sectional area instead of a larger elongated hole further helps to guide the thrust pin 22 and prevent the thrust pin 22 from being displaced during the magazine withdrawal process, thereby preventing the magazine withdrawal failure. Specifically, the cross section of the avoidance hole 1121 is a circular cross section with an area slightly larger than the corresponding cross section of the thrust pin 22, and the hole wall of the avoidance hole can guide and limit the thrust pin 22, so that the center of the needle point of the thrust pin 22 can be aligned with the drill bit more conveniently; further, the pushing-preventing pin 22 can be prevented from being deformed obliquely by the tip portion being subjected to a force during the magazine withdrawal process, and causing the magazine withdrawal failure.
