[0037] This utility model provides a clamping device for immunohistochemical staining equipment, such as... Figure 1 As shown, the device includes: a slide holder 1 and a gripper assembly 2 mounted on a robotic arm.

[0038] The slide holder 1 includes a slide frame 11 and a slide holder clamp 12. The slide frame 11 has a plurality of slide slots 111 for holding slides to be repaired. The slide holder clamp 12 is disposed on one side of the slide frame 11. The slide holder clamp 12 has slots 121 on both sides. Each slot is composed of at least two groove surfaces, which form a first included angle.

[0039] The gripper assembly 2 includes a plurality of grippers 21 arranged opposite to each other. Each gripper 21 has a plurality of protruding surfaces. The protruding surfaces form a second angle between each other. The first angle and the second angle are complementary, so that the slot 121 and the gripper 21 can be engaged and clamped by the first angle and the second angle.

[0040] In this embodiment of the invention, a gripper assembly is fixedly connected to the robotic arm in the immunohistochemical staining system. This can be achieved by screws, and this embodiment does not impose specific limitations. The gripper assembly 2 includes multiple grippers 21 with opposing sides. A motor drives the grippers to close and clamp the slide holder chuck 12 on the slide holder 1, thereby achieving the clamping of the slide holder 1. For example, the gripper assembly 2 preferably has five sets of opposing grippers 21, thus enabling the simultaneous clamping of five slide holders 1. In addition, the slide holder 1 includes a slide holder 12, which is disposed on one side of the slide holder body 11. The slide holder 12 has slots 121 on both sides. Each slot 121 consists of at least two groove surfaces that form a first angle. On the opposite side, the gripper 21 has several protrusions that form a second angle. The first angle and the second angle are complementary, so that the slot and the gripper can be engaged and clamped by the first angle and the second angle. The slide holder 1 also includes a slide frame 11. In order to increase the number of slides it can hold, the slide frame 11 has several slide slots 111 so that each slide slot 111 in one slide holder 1 can hold one slide. The multiple grippers 21 on the robotic arm can simultaneously grip multiple slide holders 1. For example, one slide holder 1 can hold 5 slides. The gripper assembly 2 is provided with 5 pairs of grippers 21. Therefore, the robotic arm can simultaneously move and place 25 slides. This embodiment of the utility model does not make specific limitations.

[0041] In one specific embodiment, to make the gripper assembly and the slide holder gripping member more stable, the slot 121 includes a first slot surface group 1211 and a second slot surface group 1212. The first slot surface group 1211 includes a first slot surface 12111, a second slot surface 12112, and a third slot surface 12113 and a fourth slot surface 12114 formed according to a first slot surface angle. The second slot surface group 1212 includes a fifth slot surface 12121, a sixth slot surface 12122, and a seventh slot surface 12123 and an eighth slot surface 12124 formed according to a fourth slot surface angle. The first slot surface angle and the second slot surface angle form a first included angle, and the third slot surface angle and the fourth slot surface angle form a third included angle.

[0042] Among them, the slide holder clamp 12 is made of metal, such as Figure 2As shown, the slide holder chuck 12 is located on one side of the slide holder body 11, i.e., the side other than the slide groove. The slide holder chuck 12 can be moved by the corresponding gripper 21 on the robotic arm. When creating the first groove surface 12111 and the second groove surface 12112, a cutting process can be performed according to the first groove surface angle. Similarly, when creating the third groove surface 12113 and the fourth groove surface 12114, a cutting process can be performed according to the second groove surface angle. When creating the fifth groove surface 12121 and the sixth groove surface 12122, a cutting process can be performed according to the third groove surface angle. When creating the seventh groove surface 12123 and the eighth groove surface 12124, a cutting process can be performed according to the fourth groove surface angle. This embodiment of the invention does not impose specific limitations. At this point, the first included angle formed by the first groove angle and the second groove angle forms a first straight line on the plane, and the third included angle formed by the third groove angle and the fourth groove angle forms a second straight line on the same plane. To achieve better clamping stability, the first and second straight lines are perpendicular to each other on the plane, thus forming a cross-shaped structure, as shown below. Figure 3 As shown. In addition, the first and third groove angles in this utility model are preferably 45 degrees, and the second and fourth groove angles are preferably 135 degrees, but can also be 60 degrees and 120 degrees. This utility model embodiment does not make specific limitations.

[0043] In a specific embodiment, in order to make the gripper assembly 2 and the slide holder 1 grip more stably, the gripper 21 includes a first protruding surface group 211 and a second protruding surface group 212. The first protruding surface group 211 includes a first protruding surface 2111, a second protruding surface 2112 and a third protruding surface 2113 and a fourth protruding surface 2114 formed according to a first protruding surface angle. The second protruding surface group 212 includes a fifth protruding surface 2121 and a sixth protruding surface 2122 formed according to a third protruding surface angle and a seventh protruding surface 2123 and an eighth protruding surface 2124 formed according to a fourth protruding surface angle.

[0044] Among them, the gripper assembly 2 is made of metal, such as Figure 4 The main view of the gripper assembly shown illustrates that each gripper assembly 2 includes two symmetrically arranged grippers 21. When creating the first protruding surface 2111 and the second protruding surface 2112, a cutting process can be performed according to the first protruding surface angle. Similarly, when creating the third protruding surface 2113 and the fourth protruding surface 2114, a cutting process can be performed according to the second protruding surface angle; when creating the fifth protruding surface 2121 and the sixth protruding surface 2122, a cutting process can be performed according to the third protruding surface angle; and when creating the seventh protruding surface 2123 and the eighth protruding surface 2124, a cutting process can be performed according to the fourth protruding surface angle. Figure 5 , 6As shown, this embodiment of the utility model is not specifically limited. In this case, the first protruding facet and the second protruding facet form the second included angle, and the third protruding facet and the fourth protruding facet form the fourth included angle. The second included angle formed by the first and second protruding facets forms a third straight line on the plane, and the fourth included angle formed by the third and fourth protruding facets forms a fourth straight line on the same plane. To achieve better clamping stability, the third and fourth straight lines are perpendicular to each other on the plane, thus forming a cross-shaped structure. Preferably, the first, second, third, and fourth protruding facets can each be 90 degrees, i.e., perpendicular to the bottom surface, thus forming a cross-shaped gap, such as... Figure 7 The image shows a side view of the gripper. In one specific embodiment, to facilitate the fitting of the slot surfaces, multiple platforms 22 can be fabricated when setting the protruding surfaces to fit with the first slot surface 12111 to the eighth slot surface 12124. At the same time, a top surface 23 can be cut out of the gripper to ensure the safety and stability when the protruding surfaces fit with the slot surfaces.

[0045] In one specific embodiment, the third included angle and the fourth included angle are complementary in order to achieve interlocking grasping. In one specific embodiment, when the third included angle is 60 degrees, the fourth included angle is 120 degrees, without specific limitation.

[0046] In a specific embodiment, in order to enable the gripper assembly 2 to grasp multiple slide holders 1 at one time, and to realize the simultaneous movement and repair of multiple slide holders 1, the gripper assembly 2 includes a plurality of first grippers 24 and a second gripper 25. The plurality of first grippers are arranged longitudinally, and the second gripper is disposed at the edge of the plurality of longitudinally arranged first grippers, and the second gripper protrudes from the plane of the first grippers.

[0047] Specifically, the multiple first grippers are arranged in a longitudinal parallel arrangement, such as... Figure 7As shown, each first gripper 24 corresponds to a slide holder 12. The robotic arm clamps the slide holder 12 by driving the relatively positioned grippers 24 to close, and releases the slide holder 12 by driving the opening and closing mechanism, thus achieving the grasping operation. In addition, to meet the gripping purposes of the robotic arm in different directions, the gripper assembly 2 also includes a second gripper 25. In this case, the second gripper 25 is positioned at the edge of the longitudinally arranged first grippers 24, which can be the upper edge or the lower edge, and can be configured based on the robotic arm's movement path and space within the immunohistochemical staining system. This embodiment of the invention does not impose specific limitations on this configuration. Simultaneously, the second gripper 25 protrudes from the plane of the first grippers 24, and the protrusion distance can be configured based on the robotic arm's movement path and space within the immunohistochemical staining system. This embodiment of the invention does not impose specific limitations on this configuration either.

[0048] In one specific embodiment, to ensure the safety and stability of the chuck, such as Figure 8 As shown, the card slot 121 also includes a third groove surface group 1213, which includes four ninth groove surfaces 12131. The length and width of each ninth groove surface 12131 can be set by cutting at one time based on the requirements of the groove surface cutting process. This utility model embodiment does not make specific limitations.

[0049] In one specific embodiment, to ensure the safe and stable gripping between the chuck and the jaws, such as Figure 8 As shown, the card slot 121 also includes a fourth groove surface group 1214, which includes two tenth groove surfaces 12141. The length and width of each tenth groove surface 12141 can be set by cutting in one go based on the requirements of the groove surface cutting process. This utility model embodiment does not make specific limitations.

[0050] In one specific embodiment, to adapt to the gripping scenario of a robotic arm holding a marking pen in an immunohistochemical staining system, and to enable the marking pen to be stably gripped for marking, the gripping device further includes a clamp 13. The clamp 13 is provided with a separable gripper 131. The separable gripper 131 includes a first separation member 1311 and a second separation member 1312. The first separation member 1311 includes a first separation surface 13111 and a first slotted surface 13112. The second separation member 1312 includes a second separation surface 13121 and a second slotted surface 13122. The first separation surface 13111 and the second separation surface 13121 are engaged by mechanical drive. The first slotted surface 13112 and the second slotted surface 13122 are provided with the slots.

[0051] Specifically, such as Figure 9As shown, the separable chuck 131 provided on the clamp 13 includes a first separating member 1311 and a second separating member 1312. The first separating surface 13111 and the second separating surface 13121 are arranged opposite to each other and are both planar. At this time, the first slotted surface 13112 and the second slotted surface 13122, which are opposite to the first separating surface 13111 and the second separating surface 13111, are provided with slots 121 with the same structure as described above, such as... Figure 10 As shown, when the detachable grippers are combined, gripping is performed based on the gripper assembly 2 on the robotic arm. This embodiment of the invention does not impose specific limitations.

[0052] In one specific embodiment, in order to fix the drawing pen, the clamp further includes a separable clamp body 14, which includes a first clamp body 141 and a second clamp body 142. The first clamp body 141 is fixedly connected to the first separating member 1311, and the second clamp body 142 is fixedly connected to the second separating member 13111. The first clamp body 141 and the second clamp body 142 are elastically connected, and the opposite surfaces of the first clamp body 141 and the second clamp body 142 are provided with grooves of the same structure.

[0053] The separable clamp 14 is made of metal, such as Figure 9 As shown, the device includes a first clamping body 141 and a second clamping body 142. To drive the separating component via the clamping bodies, the first clamping body 141 is fixedly connected to the base of the first separating component 1311, and the second clamping body 142 is fixedly connected to the base of the second separating component 13111. Furthermore, to ensure that the first clamping body 141 and the second clamping body 142 are in an open / closed state when not clamped, they are elastically connected, which may include a spring 15. This embodiment of the invention does not impose specific limitations. At this time, the marking pen is clamped by grooves of the same structure formed on the opposing surfaces of the first clamping body 141 and the second clamping body 142. These grooves include, but are not limited to, semi-circular grooves and U-shaped grooves. A motor drives the first separating component 1311 and the second separating component 1312 to separate and close, thereby realizing the taking and releasing of the marking pen.

[0054] In a specific embodiment, in order to adapt to the scenario in the immunohistochemical staining system where the robotic arm picks up the slide holder 1 and places it in the repair device, the slide holder 11 is provided with protruding parts 16 on both sides. The protruding parts 16 are used to fit into the support groove on the slide support frame, which is set on the repair cover window of the repair device.

[0055] Since the support groove and the protruding component 16 provide interlocking support, the groove structure of the support groove and the protrusion mechanism of the protruding component 16 have a complementary interlocking relationship. For example, if the support groove is a hemispherical groove, then the protrusion mechanism is a hemispherical protrusion, or as... Figure 11 The multifaceted structure of the groove shown is not specifically limited in this embodiment of the invention. Furthermore, to ensure the gripped slide can be stably immersed in the repair fluid of the repair equipment, a slide support frame is installed on the repair cover window of the repair equipment. In this case, the repair cover has a window, and slide support frames are provided on both sides of the window, which are fitted and supported by the support groove and the protruding component 16.

[0056] In one specific embodiment, in order for the gripper assembly 2 on the robotic arm to flexibly grip the slide holder 1 in the immunohistochemical staining system, the slide holder 12 and the slide are on the same horizontal and opposite surface.

[0057] In another specific embodiment, in order to allow the slide to be suspended in the restoration fluid, an elastic pressure plate 17 is provided at the front end of the slide groove 111, such as... Figure 11 As shown, at this time, the elastic clamp 17 is fixedly connected to the slide holder 11, and the elastic clamp 17 is used to hold the slide of the tissue sample. Preferably, the elastic clamp 17 is fixed to the slide holder by screws. Since it is necessary to suspend the slide in the repair solution and reduce the space occupied on the slide holder, the slide groove 111 is opened as follows. Figure 11 As shown, the elastic pressure plate 17 can be fixed to the front end of the slide groove 111 to press the glass slide placed in the slide groove 111. In addition, the material of the elastic pressure plate 17 can be elastic metal, plastic, etc., and this embodiment of the utility model does not make specific limitations.

[0058] In addition, it should be noted that the materials used in the embodiments of this utility model are all metal unless otherwise specified, and no specific limitations are imposed.

[0059] This invention provides a clamping device for immunohistochemical staining equipment. It uses a claw assembly that can simultaneously clamp multiple slides for fixed clamping, achieving the purpose of simultaneously clamping and moving multiple slides. The groove and raised surfaces are designed for stable engagement, increasing the stability of clamping and preventing slides from falling off, thus greatly improving the safety of operation.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
