Description

Technical Field

[0001] The utility model relates to the technical field of door panel processing, in particular to a positioning mechanism used for door panel processing. Background Art

[0002] At present, the door panel processing centers on the market are equipped with a positioning mechanism for positioning the door panel. The positioning mechanism mainly includes an adsorption table with several adsorption holes, and an upper positioning reference and a lower positioning reference respectively arranged on both sides of the adsorption table along the conveying direction of the door panel (i.e., the length direction of the door panel), and the upper positioning reference and the lower positioning reference can be movably installed on the bed of the door panel processing center along the width direction of the door panel to avoid interference with the conveying of the door panel. Before the door panel is conveyed over, the upper positioning reference is first moved into position in the width direction of the door panel, so that the subsequent door panel can abut against the upper positioning reference when it is conveyed over, thereby positioning the door panel at the upper positioning reference; after that, the adsorption table holds the door panel through several adsorption holes, and the door panel processing center processes the door panel; after the door panel part is processed, the lower positioning reference is moved into position in the width direction of the door panel, the adsorption table releases the adsorption of the door panel, and the door panel is conveyed in the reverse direction, then the door panel can abut against the lower positioning reference, thereby positioning the door panel at the lower positioning reference; after that, the adsorption table holds the door panel again through several adsorption holes, and the door panel processing center processes the remaining part of the door panel.

[0003] However, in the existing door panel processing center, the positions of the upper positioning reference and the lower positioning reference in the length direction of the door panel are fixed, and the following situation is very likely to occur when positioning door panels of different lengths: along the conveying direction of the door panel, the door panel is positioned at the upper positioning reference or the lower positioning reference, and the position of the positioning end is determined, but due to the length difference of the door panel, the unpositioned end of the door panel may not completely cover an adsorption hole, and may cover half or 1 / 3 of the adsorption hole, causing a part of the adsorption hole to be exposed outside, thereby weakening the adsorption and fixing force of the adsorption platform on the door panel, and ultimately reducing the adsorption reliability.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0055] The utility model relates to a door panel processing center for processing wooden door panels, and in particular to a positioning mechanism in the door panel processing center, wherein the positioning mechanism is used for positioning a door panel 110.

[0056] like Figure 1 and Figure 2As shown, the positioning mechanism involved in the utility model includes a fixedly arranged machining center bed, an adsorption table 10, an upper positioning reference 21, a lower positioning reference 22, an upper positioning drive source 31 and a lower positioning drive source 32; wherein, the adsorption table 10 is installed on the machining center bed, and the adsorption table 10 is provided with a plurality of adsorption holes 11 arranged side by side at least in the length direction of the door panel 110, and the adsorption holes 11 are connected to the vacuum generator in the door panel machining center; the upper positioning reference 21 and the lower positioning reference 22 are arranged relatively to each other along the length direction of the door panel 110, and the upper positioning reference 21 and the lower positioning reference 22 can be movably installed on the machining center bed along the length direction of the door panel 110, and the length direction of the door panel 110 is the conveying direction of the door panel 110, the upper positioning drive source 31 is transmission-connected with the upper positioning reference 21, and drives the upper positioning reference 21 to move along the length direction of the door panel 110, and the lower positioning drive source 32 is transmission-connected with the lower positioning reference 22, and drives the lower positioning reference 22 to move along the length direction of the door panel 110.

[0057] In this embodiment, the upper positioning reference 21 is used to abut against the top surface of the door panel 110, and the lower positioning reference 22 is used to abut against the bottom surface of the door panel 110. In addition, for the convenience of description, the conveying direction of the door panel 110 in the door panel processing center is defined as the front direction, and the front direction is the direction in which the door panel 110 is conveyed toward the upper positioning reference 21, and the rear direction is the direction in which the door panel 110 is conveyed toward the lower positioning reference 22. Based on this, the upper positioning reference 21 and the lower positioning reference 22 are arranged relative to each other front and back, and the upper positioning reference 21 is distributed on the front side, and the lower positioning reference 22 is distributed on the rear side.

[0058] The positioning process of the positioning mechanism in the present application is as follows: before the door panel 110 is conveyed, the upper positioning drive source 31 drives the upper positioning reference 21 to extend backward along the length direction of the door panel 110 to a specified position, which is calculated based on the length of the door panel 110 to be conveyed next, to ensure that when the top surface of the next door panel 110 abuts against the upper positioning reference 21, the door panel 110 can fully cover the adsorption holes 11 that should be covered on the adsorption platform 10. Afterwards, the door panel 110 is conveyed forward in a lying position until the top surface of the door panel 110 abuts against the extended upper positioning reference 21, and the door panel 110 is positioned at the upper positioning reference 21, as shown in FIG. Figure 1As shown, at this time, the door panel 110 completely covers the adsorption holes 11 that should be covered on the adsorption platform 10, and there is no situation where the door panel 110 covers part of the adsorption holes 11 at its bottom. Afterwards, the vacuum generator in the door panel processing center is activated, and the door panel 110 is reliably held on the adsorption platform 10 through the adsorption holes 11 of the adsorption platform 10, and the door panel processing center can process the door panel 110. After the door panel 110 is partially processed, the lower positioning drive source 32 drives the lower positioning reference 22 to extend forward along the length direction of the door panel 110 to a specified position, which is calculated based on the length of the current door panel 110 to ensure that when the bottom surface of the current door panel 110 abuts against the lower positioning reference 22, the door panel 110 can completely cover the adsorption holes 11 that should be covered on the adsorption platform 10. Afterwards, the adsorption platform 10 releases the adsorption of the door panel 110, and the door panel 110 is transported backward until the bottom surface of the door panel 110 abuts against the extended lower positioning reference 22, and the door panel 110 is positioned at the lower positioning reference 22, as shown in FIG. Figure 2 As shown, at this time, the door panel 110 completely covers the adsorption holes 11 that should be covered on the adsorption platform 10, and there is no situation where the door panel 110 covers part of the adsorption holes 11 at its top. Finally, the vacuum generator in the door panel processing center is activated again to reliably hold the door panel 110 on the adsorption platform 10 again, and the door panel processing center processes the remaining part of the door panel 110.

[0059] Therefore, the present application controls the extension length of the upper positioning datum 21 or the lower positioning datum 22 according to the length of the door panel 110 (i.e., the conveying direction of the door panel 110) by extending and retracting the upper positioning datum 21 and the lower positioning datum 22 in the length direction of the door panel 110 before the door panel 110 is conveyed into place, and door panels 110 of different lengths correspond to different extension lengths of the upper positioning datum 21 or the lower positioning datum 22, ensuring that after the door panels 110 of different lengths are positioned by abutting against the upper positioning datum 21 or the lower positioning datum 22, the door panels 110 of different lengths can fully cover the adsorption holes 11 that should be covered on the adsorption platform 10, so as to improve the adsorption and holding effect of the adsorption platform 10 on the door panel 110, and ultimately improve the processing quality of the door panel 110.

[0060] Furthermore, if Figure 1 and Figure 2 As shown, there are two adsorption platforms 10 symmetrically distributed along the width direction of the door panel 110 , and are used to adsorb and fix the left and right sides of the bottom of the door panel 110 respectively.

[0061] Furthermore, if Figure 1 and Figure 2As shown, the door panel processing center has a top processing device 60, a bottom processing device 70, a left side processing device 80 and a right side processing device 90; when the top surface of the door panel 110 is positioned at the upper positioning reference 21, the top processing device 60, the left side processing device 80 and the right side processing device 90 are respectively distributed on the front side, the left side and the right side of the door panel 110, and the top surface, the left side and the right side of the door panel 110 are processed respectively; when the bottom surface of the door panel 110 is positioned at the lower positioning reference 22, the bottom processing device 70, the left side processing device 80 and the right side processing device 90 are respectively distributed on the back side, the left side and the right side of the door panel 110, and the bottom surface, the left side and the right side of the door panel 110 are processed respectively.

[0062] Preferably, if Figure 1 and Figure 2 As shown, the top processing equipment 60 includes a top frame 61, a top processing head 62 mounted on the top frame 61 in a three-axis motion, and at least one top processing tool set 63 mounted on the top processing head 62. The top frame 61 can be mounted on the machining center bed in a left-right motion along the width direction of the door panel 110. The three-axis motion of the top processing head 62 means that the top processing head 62 can move forward and backward, left and right, and up and down, and the movement in each direction is driven by a servo motor.

[0063] Preferably, if Figure 1 and Figure 2 As shown, the bottom processing equipment 70 includes a bottom frame 71, a bottom processing head 72 mounted on the bottom frame 71 in a three-axis motion, and at least one bottom processing tool set 73 mounted on the bottom processing head 72. The bottom frame 71 can be mounted on the machining center bed in a left-right motion along the width direction of the door panel 110. The three-axis motion of the bottom processing head 72 means that the bottom processing head 72 can move forward and backward, left and right, and up and down, and the movement in each direction is driven by a servo motor.

[0064] Preferably, if Figure 1 and Figure 2 As shown, the left processing device 80 includes a left frame 81, a left processing head 82 mounted on the left frame 81 in a three-axis motion, and at least one left processing tool group 83 mounted on the left processing head 82. The left frame 81 can be mounted on the machining center bed in a left-right movable manner along the width direction of the door panel 110. The three-axis motion of the left processing head 82 means that the left processing head 82 can move forward and backward, left and right, and up and down, and the movement in each direction is driven by a servo motor.

[0065] Preferably, if Figure 1 and Figure 2As shown, the right processing device 90 includes a right frame 91, a right processing head 92 mounted on the right frame 91 in a three-axis motion, and at least one right processing tool set 93 mounted on the right processing head 92. The right frame 91 can be mounted on the machining center bed in a left-right motion along the width direction of the door panel 110. The three-axis motion of the right processing head 92 means that the right processing head 92 can move forward and backward, left and right, and up and down, and the movement in each direction is driven by a servo motor.

[0066] In this embodiment, the top frame 61, the bottom frame 71, the left frame 81 and the right frame 91 can be moved left and right to avoid the top processing device 60, the bottom processing device 70, the left processing device 80 and the right processing device 90 from interfering with the conveying of the door panel 110. Of course, in other embodiments, the top frame 61, the bottom frame 71, the left frame 81 and the right frame 91 can also be arranged to be installed on the machining center bed in a manner that they can move up and down to avoid interfering with the conveying of the door panel 110.

[0067] In the positioning mechanism involved in the present application, the installation structure of the upper positioning drive source 31, the lower positioning drive source 32, the upper positioning reference 21 and the lower positioning reference 22 is preferably: Figure 1 and Figure 2 As shown, the upper positioning drive source 31 is mounted on the top frame 61, and the upper positioning reference 21 is mounted on the top frame 61 so as to be movable forward and backward; the lower positioning drive source 32 is mounted on the bottom frame 71, and the lower positioning reference 22 is mounted on the bottom frame 71 so as to be movable forward and backward. Particularly preferably, the upper positioning drive source 31 is mounted on the top processing head 62, and the upper positioning reference 21 is mounted on the top processing head 62 so as to be movable forward and backward; the lower positioning drive source 32 is mounted on the bottom processing head 72, and the lower positioning reference 22 is mounted on the bottom processing head 72 so as to be movable forward and backward. In this way, when the door panel 110 is conveyed forward, the lower frame 71 avoids on one side of the conveying path of the door panel 110, so as to avoid the lower positioning drive source 32 and the lower positioning reference 22 from interfering with the conveying of the door panel 110. When the door panel 110 is completely processed and needs to be transported forward from the door panel processing center, the top frame 61 is avoided to one side of the conveying path of the door panel 110, so as to avoid interference of the upper positioning drive source 31 and the upper positioning reference 21 with the conveying of the door panel 110.

[0068] Furthermore, if Figure 1 and Figure 2As shown, both the upper positioning drive source 31 and the lower positioning drive source 32 are cylinders, the piston rods of which can be extended and retracted along the length direction of the door panel 110, the upper positioning reference 21 is fixed to the rear end of the cylinder piston rod of the upper positioning drive source 31, and the lower positioning reference 22 is fixed to the front end of the cylinder piston rod of the lower positioning drive source 32. Preferably, there are multiple upper positioning references 21, which are arranged side by side along the width direction of the door panel 110, and each upper positioning reference 21 is connected to a corresponding upper positioning drive source 31; there are multiple lower positioning references 22, which are arranged side by side along the width direction of the door panel 110, and each lower positioning reference 22 is connected to a corresponding lower positioning drive source 32.

[0069] Furthermore, if Figure 1 and Figure 2 As shown, the positioning mechanism also includes a left clamping member 41, a right clamping member 42, a left clamping drive source 51 and a right clamping drive source 52; the left clamping member 41 and the right clamping member 42 are relatively arranged left and right along the width direction of the door panel 110, and the left clamping member 41 and the right clamping member 42 can be installed on the machining center bed so as to be movable left and right along the width direction of the door panel 110; the left clamping drive source 51 is transmission connected to the left clamping member 41 to drive the left clamping member 41 to move left and right; the right clamping drive source 52 is transmission connected to the right clamping member 42 to drive the right clamping member 42 to move left and right. When the door panel 110 is positioned at the upper positioning reference 21 or the lower positioning reference 22, the left clamping drive source 51 drives the left clamping member 41 to extend to the right until it abuts against the left side of the door panel 110, and the right clamping drive source 52 drives the right clamping member 42 to extend to the left until it abuts against the right side of the door panel 110, thereby clamping the door panel 110 by the left clamping member 41 and the right clamping member 42, thereby more reliably preventing the door panel 110 from being offset during the processing.

[0070] In the positioning mechanism involved in the present application, the installation structure of the left clamping member 41, the right clamping member 42, the left clamping drive source 51 and the right clamping drive source 52 is preferably: Figure 1 and Figure 2 As shown, the left clamping drive source 51 is mounted on the left processing head 82, and the left clamping member 41 is mounted on the left processing head 82 so as to be movable left and right along the width direction of the door panel 110; the right clamping drive source 52 is mounted on the right processing head 92, and the right clamping member 42 is mounted on the right processing head 92 so as to be movable left and right along the width direction of the door panel 110. In this way, during the conveying process of the door panel 110, the left frame 81 avoids the left side of the conveying path of the door panel 110, thereby preventing the left clamping member 41 and the left clamping drive source 51 from interfering with the conveying of the door panel 110, and the right frame 91 avoids the right side of the conveying path of the door panel 110, thereby preventing the right clamping member 42 and the right clamping drive source 52 from interfering with the conveying of the door panel 110.

[0071] Furthermore, if Figure 1and Figure 2 As shown, the left clamping drive source 51 and the right clamping drive source 52 are both cylinders, the piston rods of the cylinders can be extended and retracted along the length direction of the door panel 110, the left clamping member 41 is fixed to the right end of the cylinder piston rod of the left clamping drive source 51, and the right clamping member 42 is fixed to the left end of the cylinder piston rod of the right clamping drive source 52.

[0072] Preferably, the upper positioning reference 21, the lower positioning reference 22, the left clamping member 41 and the right clamping member 42 are all made of straight rulers.

[0073] In summary, the present application sets the upper positioning reference 21 and the lower positioning reference 22 as a retractable structure along the conveying direction of the door panel 110, and first extends the upper positioning reference 21 or the lower positioning reference 22 to a position before positioning the door panel 110, and then after positioning the conveyed door panel 110, it can ensure that the door panels 110 of different lengths can fully cover the adsorption holes 11 that should be covered on the adsorption platform 10, so as to improve the adsorption and holding effect of the adsorption platform 10 on the door panel 110, and finally improve the processing quality of the door panel 110. Therefore, the present utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
