[0039] The technical solution of the utility model will be described below in conjunction with embodiments and drawings.

[0040] First, see Figures 1 to 4 The embodiment of the present application discloses a gantry mechanism, including a Y-axis displacement assembly 100, a guide support assembly 200 and an X-axis displacement assembly 300.

[0041] The Y-axis displacement assembly 100 includes a first mounting body 110, a first driving member 120, and a first movable member 130. The first driving member 120 and the first movable member 130 are both disposed on the first mounting body 110. The first driving member 120 is connected to the first movable member 130, and the first driving member 120 is configured to drive the first movable member 130 to move along the Y-axis direction. For example, the Y-axis direction is a horizontal direction. Figure 1 The direction shown is Y. The first mounting body 110 may be a mounting bracket, a mounting seat, a mounting plate or a mounting frame, the first driving member 120 may be a servo motor, a linear motor or a pneumatic motor, and the first movable member 130 may be a sliding seat, a slider or a sliding plate.

[0042] One end of the X-axis displacement assembly 300 in the X-axis direction is connected to the first movable member 130, and the first movable member 130 is configured to drive the X-axis displacement assembly 300 to move in the Y-axis direction. The X-axis displacement assembly 300 is configured to drive the load module to move in the X-axis direction. Exemplarily, the X-axis direction is another horizontal direction perpendicular to the Y-axis direction. Figure 1 The load module refers to a functional module loaded on the X-axis displacement assembly 300.

[0043] The guide support assembly 200 includes a follower cam structure 220 and a guide support member 210, wherein the guide support member 210 extends in the Y-axis direction, and the follower cam structure 220 rolls and contacts the guide support member 210. The other end of the X-axis displacement assembly 300 in the X-axis direction is connected to the follower cam structure 220, and the follower cam structure 220 is configured to roll on the guide support member 210 following the displacement of the X-axis displacement assembly 300 in the Y-axis direction.

[0044] In other words, both ends of the X-axis displacement assembly 300 in the X-axis direction are supported on the Y-axis displacement assembly 100 and the guide support assembly 200 respectively, thereby forming a gantry mechanism.

[0045] The gantry mechanism drives the X-axis displacement assembly 300 to move along the Y-axis direction through the first movable member 130 of the Y-axis displacement assembly 100. The follower cam structure 220 is configured to follow the X-axis displacement assembly 300 to move along the Y-axis direction and roll on the guide support member 210. The guide support assembly 200 makes the structure of the gantry mechanism simpler, requires fewer parts, and has lower equipment costs.

[0046] The follower cam structure 220 rolls in contact with the guide support 210 . The rolling contact has the characteristic of small resistance, so that the displacement of both ends of the X-axis displacement assembly 300 is more coordinated, thereby improving the position accuracy of the load module.

[0047] In a possible implementation of the first aspect, Figure 1 and Figure 3 As shown, the follower cam structure 220 includes an upper follower cam 221 and a lower follower cam 222. The upper follower cam 221 rolls in contact with the upper side surface 211 of the guide support 210, and the lower follower cam 222 rolls in contact with the lower side surface 212 of the guide support 210. The upper follower cam 221 and the lower follower cam 222 cooperate with the guide support 210 from the upper and lower sides respectively to form a snap-fit ​​effect, so that the follower cam structure 220 is fixed in the vertical direction and stably displaced in the horizontal direction.

[0048] Preferably, if Figure 1As shown, the follower cam structure 220 further includes a cam mounting member 223, and the upper follower cam 221 and the lower follower cam 222 are both arranged on the cam mounting member 223. Exemplarily, the cam mounting member 223 may be a mounting plate, a mounting block, a mounting bracket or a mounting seat, and the cam mounting member 223 serves to mount the upper follower cam 221 and the lower follower cam 222, and enables the upper follower cam 221 and the lower follower cam 222 to be connected to the X-axis displacement assembly 300. Specifically, the upper follower cam 221 and the lower follower cam 222 both include a rotating shaft and a roller, and the roller is rotatably connected to the cam mounting member 223 via the rotating shaft.

[0049] Preferably, if Figure 1 As shown, the guide support 210 is a strip guide plate. The structure of the strip guide plate is relatively simple, and has both good support and guide effects. Further, the guide support 210 is configured to be fixedly set, for example, the guide support 210 is fixedly set on an external frame or base, so that the upper follower cam 221 and the lower follower cam 222 move on a fixed track.

[0050] Preferably, if Figure 1 and Figure 3 As shown, the axial directions of the upper follower cam 221 and the lower follower cam 222 are in the same direction as the X-axis direction, and the first driving member 120 drives the second mounting body 310 to displace in the Y-axis direction. The force direction of the second mounting body 310 acting on the upper follower cam 221 and the lower follower cam 222 is in the Y-axis direction, and the Y-axis direction is perpendicular to the X-axis direction. The upper follower cam 221 and the lower follower cam 222 are subjected to a force perpendicular to their axial directions, thereby achieving higher movement efficiency, and higher displacement synchronization of the Y-axis displacement assembly 100 and the guide support assembly 200.

[0051] Preferably, if Figure 1 As shown, there are two upper follower cams 221 and one lower follower cam 222. In the Y-axis direction, the lower follower cam 222 is located between the two upper follower cams 221. In other words, the two upper follower cams 221 and one lower follower cam 222 are distributed in an isosceles triangle, and this distribution has higher force stability, and the guide support assembly 200 has better load-bearing performance and a more stable structure.

[0052] In a possible implementation of the first aspect, see Figure 3The X-axis displacement assembly 300 includes a second mounting body 310, a second driving member 320, and a second movable member 330. Exemplarily, the second mounting body 310 may be a mounting arm, a mounting bracket, a mounting plate, or a mounting seat, the second driving member 320 may be a servo motor, a linear motor, or a pneumatic motor, and the second movable member 330 may be a slide seat, a slider, or a sliding plate.

[0053] The two ends of the second installation body 310 in the X-axis direction are respectively fixedly connected to the follower cam structure 220 and the first movable member 130. Specifically, one end of the second installation body 310 in the X-axis direction is connected to the cam installation member 223.

[0054] The second driving member 320 is arranged at one end of the second installation body 310 close to the first movable member 130, the second movable member 330 is movably arranged on the second installation body 310 and is drivingly connected to the second driving member 320, the second driving member 320 is configured to drive the second movable member 330 to move along the X-axis direction, and the second movable member 330 is configured to be connected to the load module. In other words, when the second movable member 330 moves along the X-axis direction, the load module also moves along the X-axis direction. The first movable member 130 drives the X-axis displacement assembly 300 to move in the Y-axis direction, that is, the load module can move in both the X-axis direction and the Y-axis direction.

[0055] Since the second driving member 320 is arranged at one end of the second mounting body 310 close to the first movable member 130, that is, the load of the second driving member 320 is at the active displacement end of the second mounting body 310, the above design reduces the load at one end of the second mounting body 310 connected to the cam mounting member 223, thereby making the displacement resistance of the driven end of the second mounting body 310 smaller and the displacement synchronization of the two ends of the second mounting body 310 better.

[0056] For further information, see Figure 3 The X-axis displacement assembly 300 further includes an electrical box 340 , which is disposed at one end of the second mounting body 310 close to the first movable member 130 , and the second driving member 320 is disposed in the electrical box 340 .

[0057] The electrical box 340 is used to set electrical parts and the second driving member 320, and plays the role of storing parts, making the structure more compact. In other words, most of the load on the X-axis displacement assembly 300 is concentrated on the electrical box 340, further reducing the load on one end of the second installation body 310 connected to the cam installation member 223, thereby making the displacement synchronization of the two ends of the second installation body 310 better and more coordinated.

[0058] In a possible implementation of the first aspect, see Figure 3, the X-axis displacement assembly 300 also includes a harness groove 350, and the two ends of the harness groove 350 in the X-axis direction are fixedly connected to the follower cam structure 220 and the electrical box 340 respectively. Specifically, one end of the harness groove 350 in the X-axis direction is fixedly connected to the cam mounting member 223 of the follower cam structure 220. The harness groove 350 is arranged parallel to the second mounting body 310. The harness groove 350 is configured to accommodate the harness extending from the electrical box 340 to the load module. When the load module is displaced in the X-axis direction, the harness connected to the load module is constrained in the harness groove 350 to prevent the harness from being entangled in other moving parts. The present application also utilizes the electrical box 340 and the follower cam structure 220 as the support structure of the harness groove 350, and there is no need to set up additional support members to support the harness groove 350, so as to simplify the structure and reduce the equipment cost.

[0059] In a possible implementation of the first aspect, see Figure 3 The X-axis displacement assembly 300 further includes a belt 360 and an X-axis guide rail 370. The belt 360 and the X-axis guide rail 370 are both arranged on the second mounting body 310, and the second driving member 320 is drivingly connected to the belt 360. For example, the second driving member 320 is a motor, the second mounting body 310 is a mounting arm, a driving pulley is arranged on the output shaft of the motor, a driven pulley is arranged on the end of the mounting arm away from the driving pulley, the driving pulley and the driven pulley are arranged at intervals, and the two ends of the belt 360 are respectively sleeved on the driving pulley and the driven pulley, and then the motor drives the driving pulley to rotate, the driving pulley drives the belt to rotate, and the driven pulley rotates drivenly.

[0060] The second movable member 330 is fixedly connected to the belt 360 and slidably connected to the X-axis guide rail 370. For example, the second movable member 330 is an X-axis slider, and the X-axis slider is fixedly connected to a portion of the belt 360 and slidably connected to the X-axis guide rail 370. The second driving member 320 is configured to drive the belt 360 to rotate and drive the second movable member 330 to slide on the X-axis guide rail 370. The X-axis displacement assembly 300 drives the second movable member 330 to move in the X-axis direction by means of the belt 360 transmission. The belt 360 transmission structure has the advantages of light weight and low cost, which is conducive to reducing the load of the Y-axis displacement assembly 100 and the guide support assembly 200 and improving the displacement synchronization.

[0061] In a possible implementation of the first aspect, see Figure 4 The first driving member 120 is a linear motor, which includes a stator 121 and a mover 122. The stator 121 is disposed on the first mounting body 110, and the mover 122 is movably connected to the stator 121. The Y-axis displacement assembly 100 also includes a Y-axis guide rail 170, and the first movable member 130 is fixedly connected to the mover 122 and slidably connected to the Y-axis guide rail 170.

[0062] Compared with the Y-axis displacement assembly using belt drive in the related art, the Y-axis displacement assembly 100 of the present application drives the slide to move along the Y-axis guide rail 170 through the mover 122 of the linear motor. The linear motor has the characteristics of low friction, stable structure and high precision, and can drive the Y-axis displacement assembly 100 to move smoothly and accurately.

[0063] In a possible implementation of the first aspect, see Figure 4 The first installation body 110 has a vertical surface 111, and the first movable member 130 is vertically arranged on the vertical surface 111 to reduce the area occupied by the first movable member 130 on the horizontal plane.

[0064] The first movable member 130 is provided with a support platform 133 protruding along the X-axis direction, and one end of the X-axis displacement assembly 300 is fixed on the support platform 133. Specifically, one end of the second mounting body 310 of the X-axis displacement assembly 300 is fixed on the support platform 133, and the support platform 133 is used to increase the force bearing area of ​​the first movable member 130, and when the first movable member 130 is vertically arranged, a good support effect is maintained for the X-axis displacement assembly 300.

[0065] In a possible implementation of the first aspect, see Figure 5 The Y-axis displacement assembly 100 further includes a magnetic scale 140, which includes a reading head 141 and a fixed magnetic scale 142. The fixed magnetic scale 142 is disposed on the first mounting body 110 and extends along the Y-axis direction, and the reading head 141 is disposed on the first movable member 130. When the slide moves along the Y-axis direction, the reading head 141 moves relative to the fixed magnetic scale 142, and then the displacement of the slide is measured by the reading head 141, so as to control the slide.

[0066] For further information, see Figure 5, the Y-axis displacement assembly 100 further includes a first photoelectric sensor 150 and a second photoelectric sensor 160, which are respectively arranged at both ends of the first mounting body 110 in the Y-axis direction. The first movable member 130 is respectively provided with a first trigger member 131 and a second trigger member 132 on both sides in the Y-axis direction. Exemplarily, the first trigger member 131 and the second trigger member 132 may be plate-shaped members or block-shaped members, and only need to be able to trigger the first photoelectric sensor 150 and the second photoelectric sensor 160. The first trigger member 131 is configured to trigger the first photoelectric sensor 150, and the second trigger member 132 is configured to trigger the second photoelectric sensor 160. When the first movable member 130 is displaced to one end of the stroke along the Y-axis direction, the first trigger member 131 triggers the first photoelectric sensor 150. When the first movable member 130 is displaced to the other end of the stroke along the Y-axis direction, the second trigger member 132 triggers the second photoelectric sensor 160. When the first photoelectric sensor 150 or the second photoelectric sensor 160 is triggered, the first driving member 120 stops working and the first movable member 130 stops moving, thereby playing a role of displacement limiting and realizing precise control of the stroke.

[0067] In the second aspect, the embodiment of the present application discloses a translation test sorting machine, including a gantry mechanism and a load module as in the first aspect. Exemplarily, the load module is a nozzle device. Specifically, the load module is connected to the second movable member 330. The second movable member 330 drives the load module to move in the X-axis direction, and the second movable member 330 can move in the Y-axis direction, thereby causing the load module to move in the X-axis direction and the Y-axis direction.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
