The drive mechanism 4 is capable of driving the adsorption mechanism 5 to reciprocate between a first position and a second position along the first direction x.

[0057] The adsorption mechanism 5 includes a lifting drive component 51, a first adsorption component 52 and a second adsorption component 53. The lifting drive component 51 is used to drive the first adsorption component 52 and the second adsorption component 53 to rise and fall synchronously along the second direction z. The first direction x and the second direction z are not parallel and not collinear.

[0058] The first adsorption component 52 is capable of adsorbing the separator paper 300 in the stacked material 400 when the adsorption mechanism 5 is in the first position, and releasing the adsorbed separator paper 300 to the separator paper recovery platform 1 when the adsorption mechanism 5 moves to the second position.

[0059] The plate placing device 100 provided by the embodiment of the present invention drives the adsorption mechanism 5 as a whole to reciprocate between the first position and the second position along the first direction x through the driving mechanism 4, and drives the first adsorption component 52 and the second adsorption component 53 to rise and fall synchronously along the second direction z through the lifting driving component 51.

[0060] In one embodiment, if Figure 1 As shown, the first adsorption assembly 52 and the second adsorption assembly 53 are spaced apart along the first direction x to avoid mutual interference between the first adsorption assembly 52 and the second adsorption assembly 53 .

[0061] In one embodiment, if Figure 1As shown, when the adsorption mechanism 5 is in the first position, the first adsorption component 52 is located above the stacking platform 2 along the second direction z, so that the first adsorption component 52 can adsorb the separator 300 in the stacked material 400. At the same time, the second adsorption component 53 is located above the loading platform 3 along the second direction z, so that the second adsorption component 53 can release the adsorbed workpiece 200 to the loading platform 3 to achieve material transportation.

[0062] When the adsorption mechanism 5 is in the second position, the first adsorption component 52 is located above the separator paper recovery platform 1 along the second direction z, so that the first adsorption component 52 can release the adsorbed separator paper 300 to the separator paper recovery platform 1. At the same time, the second adsorption component 53 is located above the stacking platform 2 along the second direction z, so that the second adsorption component 53 can adsorb the workpiece 200 to be tested in the stacked material 400.

[0063] In one embodiment, if Figure 1 and Figure 2 As shown, the suction mechanism 5 further includes a paper separator detector 54 and a workpiece detector 55. The paper separator detector 54 is connected to the first suction assembly 52 and is configured to detect whether the top layer of the stacked material 400 is the paper separator 300 when the suction mechanism 5 is in the first position. When the suction mechanism 5 is in the first position and the top layer of the stacked material 400 is the paper separator 300, the first suction assembly 52 is capable of sucking the top layer of the paper separator 300 of the stacked material 400.

[0064] The workpiece detector 55 is connected to the second suction assembly 53 and is configured to detect whether the top layer of the stacked material 400 is the workpiece 200 when the suction mechanism 5 is in the second position. When the suction mechanism 5 is in the second position and the top layer of the stacked material 400 is the workpiece 200, the second suction assembly 53 can suction the top layer of the stacked material 400.

[0065] In one embodiment, if Figure 2 As shown, the lifting drive assembly 51 includes a lifting drive component 511 and a lifting bracket 512. The lifting drive component 511 is used to drive the lifting bracket 512 to move up and down along the second direction z.

[0066] The first adsorption assembly 52 and the second adsorption assembly 53 are both mounted on the lifting bracket 512. The lifting bracket 512 is driven to rise and fall along the second direction z by the lifting driving component 511, thereby driving the first adsorption assembly 52 and the second adsorption assembly 53 to rise and fall synchronously along the second direction z.

[0067] In one embodiment, if Figure 2As shown, the lifting bracket 512 includes a lifting plate 5121, a first connecting rod 5122 and a second connecting rod 5123. The lifting drive component 511 is used to drive the lifting plate 5121 to lift and lower along the second direction z. The first connecting rod 5122 is connected between the first adsorption component 52 and the lifting plate 5121, and the second connecting rod 5123 is connected between the second adsorption component 53 and the lifting plate 5121, thereby realizing the connection between the lifting bracket 512 and the first adsorption component 52 and the second adsorption component 53.

[0068] In one embodiment, if Figure 2 As shown, the first adsorption assembly 52 includes a first linkage plate 521 and a plurality of first adsorption units 522. The plurality of first adsorption units 522 are installed on the first linkage plate 521 at intervals along the third direction y to form the first adsorption assembly 52. ​​A first connecting rod 5122 is connected between the first linkage plate 521 and the lifting plate 5121 to connect the lifting bracket 512 to the first adsorption assembly 52.

[0069] The second adsorption assembly 53 includes a second linkage plate 531 and a plurality of second adsorption units 532. The plurality of second adsorption units 532 are installed on the second linkage plate 531 at intervals along the third direction y to form the second adsorption assembly 53. The second connecting rod 5123 is connected between the second linkage plate 531 and the lifting plate 5121 to connect the lifting bracket 512 to the second adsorption assembly 53.

[0070] The first direction x, the second direction z, and the third direction y are not parallel to each other and are not collinear. The paper separation detector 54 is connected to the first linkage plate 521 , and the workpiece detector 55 is connected to the second linkage plate 531 .

[0071] In one embodiment, if Figure 1 As shown, the first direction x and the third direction y are horizontal directions, the second direction z is a vertical direction, and the first direction x, the second direction z and the third direction y are perpendicular to each other.

[0072] In one embodiment, the first direction x is the length direction of the base 6 , the second direction z is the height direction of the base 6 , and the third direction y is the width direction of the base 6 .

[0073] In one embodiment, if Figure 2 As shown, the lifting drive component 511 is a cylinder, and the output end of the cylinder is connected to the lifting bracket 512 to achieve the lifting of the lifting bracket 512 along the second direction z. In other embodiments not shown in the figure, the lifting drive component can also be a hydraulic cylinder, a linear motor or a servo cylinder.

[0074] In one embodiment, if Figure 2As shown, the drive mechanism 4 includes a drive assembly 41 and a drive plate 42. The drive assembly 41 is used to drive the drive plate 42 to move along the first direction x. The lifting drive assembly 51 is mounted on the drive plate 42. When the drive assembly 41 drives the drive plate 42 to move along the first direction x, the drive plate 42 drives the lifting drive assembly 51 to move along the first direction x, so that the adsorption mechanism 5 as a whole reciprocates between the first position and the second position along the first direction x.

[0075] In one embodiment, if Figure 2 As shown, the driving assembly 41 is a linear motor to drive the driving plate 42 along the first direction x. In other embodiments not shown in the figures, the driving assembly can also be a cylinder, a hydraulic cylinder or a servo electric cylinder.

[0076] In one embodiment, if Figure 3 As shown, the paper separation recovery platform 1 includes a first support plate 11 and a first support plate driving component 12. The first support plate 11 is used to carry the paper separation 300. The first support plate driving component 12 is used to drive the first support plate 11 to rise and fall along the second direction z to drive the paper separation 300 on the first support plate 11 to rise and fall along the second direction z.

[0077] In one embodiment, if Figure 3 As shown, the first support plate driving component 12 includes a first motor 122 and a first screw 121. The first screw 121 includes a first nut and a first screw threadedly connected to the first nut. The first motor 122 is used to drive the first nut to rotate, and one end of the first screw is rotatably connected to the first support plate 11.

[0078] The axis of the first screw rod extends along the second direction z, and the axis of the first screw rod is perpendicular to the side surface of the first support plate 11 that supports the separator paper 300 .

[0079] When the first motor 122 is working, the first nut rotates and drives the first screw rod threadedly connected thereto to move axially, thereby driving the first support plate 11 to move along the second direction z.

[0080] In other embodiments not shown in the figures, the first support plate driving component can also be directly driven by a linear motor or a cylinder, or can be driven by a motor in conjunction with a belt drive assembly or a chain drive assembly.

[0081] In one embodiment, if Figure 3 As shown, the paper collecting platform 1 further includes a paper collecting plate 13, which is arranged around at least a portion of the first support plate 11 in a direction perpendicular to the second direction z. The first support plate 11 is slidably connected to the paper collecting plate 13 along the second direction z. The provision of the paper collecting plate 13 can guide and limit the movement of the first support plate 11 along the second direction z, and can also enclose the paper collecting plates 300 stacked on the first support plate 11 to prevent the paper collecting plates 300 from sliding laterally off the first support plate 11.

[0082] In one embodiment, if Figure 3 and Figure 4 As shown, the paper collecting station 1 further includes a paper collecting sensor 14, which is mounted on the paper collecting plate 13. The paper collecting sensor 14 is used to detect whether the topmost layer of paper collecting 300 on the first supporting plate 11 is at a preset height.

[0083] The first support plate driving component 12 is used to drive the first support plate 11 to descend along the second direction z when the uppermost layer of separation paper 300 on the first support plate 11 is at a preset height, so as to continue to stack the separation paper 300.

[0084] The provision of the paper arrival sensor 14 can shorten the distance that the paper 300 falls when the first adsorption component 52 releases the paper 300. When the top layer of paper 300 on the first support plate 11 is at a preset height, the first support plate driving component 12 can drive the first support plate 11 to descend a small amount (e.g., 2 cm or 3 cm) along the second direction z to continue stacking the paper 300. Furthermore, this can ensure that the height of the top layer of paper 300 on the first support plate 11 is no higher than the height of the stacked material 400, thereby achieving synchronous adsorption and release of the first adsorption component 52 and the second adsorption component 53. When the first adsorption component 52 adsorbs the paper 300, the second adsorption component 53 simultaneously releases the workpiece 200 to be measured. When the first adsorption component 52 releases the paper 300, the second adsorption component 53 simultaneously adsorbs the workpiece 200 to be measured.

[0085] In one embodiment, if Figure 3 As shown, the stacking platform 2 includes a second support plate 21 and a second support plate driving component 22. The second support plate 21 is used to carry the stacked material 400. The second support plate driving component 22 is used to drive the second support plate 21 to rise and fall along the second direction z to drive the stacked material 400 on the second support plate 21 to rise and fall along the second direction z.

[0086] In one embodiment, if Figure 3 As shown, the second support plate driving component 22 includes a second motor 222 and a second screw 221. The second screw 221 includes a second nut and a second screw threadedly connected to the second nut. The second motor 222 is used to drive the second nut to rotate, and one end of the second screw is rotatably connected to the second support plate 21.

[0087] The axis of the second screw rod extends along the second direction z, and the axis of the second screw rod is perpendicular to a side surface of the second support plate 21 that supports the stacked materials 400 .

[0088] When the second motor 222 is working, the second nut rotates and drives the second screw rod threadably connected thereto to move axially, thereby driving the second support plate 21 to move along the second direction z.

[0089] In other embodiments not shown in the figures, the second support plate driving component can also be directly driven by a linear motor or a cylinder, or can be driven by a motor in conjunction with a belt drive assembly or a chain drive assembly.

[0090] In one embodiment, if Figure 3 As shown, the stacking platform 2 further includes a material enclosure 23, which is arranged around at least a portion of the second support plate 21 in a direction perpendicular to the second direction z. The second support plate 21 is slidably connected to the material enclosure 23 along the second direction z. The material enclosure 23 can guide and limit the movement of the second support plate 21 along the second direction z, and can also limit the stacking material 400 stacked on the second support plate 21.

[0091] In one embodiment, if Figure 1 As shown, the plate placing device 100 also includes a base 6 and a support frame 7 installed on the base 6. The paper recovery table 1, the stacking table 2 and the loading table 3 are respectively installed on the base 6, and the driving mechanism 4 is installed on the support frame 7 to realize the installation of each structure.

[0092] The working principle of the board placement device 100 provided in the embodiment of the present invention is as follows:

[0093] When the top layer of the stacked material 400 is the separator 300 , the driving mechanism 4 drives the adsorption mechanism 5 to move along the first direction x to the first position, and the first adsorption component 52 is lifted and lowered by the lifting driving component 51 to adsorb the top layer of the separator 300 .

[0094] Then, the driving mechanism 4 drives the adsorption mechanism 5 to move from the first position to the second position, and the first adsorption component 52 releases the adsorbed spacer 300 to the spacer recovery platform 1 for recovery. At the same time, the second adsorption component 53 adsorbs the workpiece 200 to be tested, which is located on the top layer of the stacked material 400.

[0095] Then, the drive mechanism 4 drives the suction mechanism 5 from the second position to the first position. The second suction assembly 53 releases the workpiece 200 it has suctioned onto the loading platform 3, completing the material conveying process. Simultaneously, the first suction assembly 52 suctions the separator paper 300, now located on the top layer of the stacked material 400.
