[0045] Furthermore, part detection sensors 20 are provided on the support 15, and multiple part detection sensors 20 can be provided. The multiple part detection sensors 20 are preferably arranged at positions close to the positioning pin 16;

[0046] In this embodiment, the part detection sensor 20 is used to identify whether the part exists;

[0047] An inductive coupling receiver 21 is provided on the glue application trolley 4, and both the part detection sensor 20 and the inductive coupling receiver 21 are coupled to the PLC control cabinet 3.

[0049] Specifically, the storage - location frame 22 includes two parallel connecting rods 30. At one - side position of the two connecting rods 30, a cross - bar 31 is connected. The clamping cylinder 23, the valve island 25, and the triple - component unit 24 are arranged on the upper surface of the cross - bar 31. The clamping cylinder 23 is used for clamping and fixing the glue - applying trolley 4. The valve island 25 is coupled with the clamping cylinder 23 and is simultaneously signal - connected to the PLC control cabinet 3. The valve island 25 controls the opening and closing of the clamping cylinder 23 by receiving the signal from the PLC control cabinet 3.

[0050] The triple - component unit 24 includes a pressure - reducing valve, a filter, and an oil - mist lubricator. Among them, the pressure - reducing valve is used to adjust the pressure of the compressed air, thereby realizing the adjustment of the clamping force of the clamping cylinder 23.

[0051] The inductive - coupling transmitter 26 and the sensing component 27 are arranged on the inner side wall of the cross - bar 31. Among them, multiple sensing components 27 can be provided. The sensing component 27 includes a mounting bracket 32 and a trolley detection sensor 33. The trolley detection sensor 33 is mounted on the cross - bar 31 through the mounting bracket 32.

The trolley detection sensor 33 and the inductive - coupling transmitter 26 are both coupled to the PLC control cabinet 3, and there is a wireless connection between the inductive - coupling transmitter 26 and the inductive - coupling receiver 21;

[0052] In this embodiment, the trolley detection sensor 33 is used to identify the position and quantity of the trolley number identification plate 13. According to the position and quantity of the trolley number identification plate 13 identified by the trolley detection sensor 33, which correspond one - to - one with the number of the glue - applying trolley 4, the identification of the number of the glue - applying trolley 4 is realized;

[0053] Furthermore, a guide rail 34 adapted to the guiding component 28 is arranged on the side of the glue - applying trolley 4.

[0054] The guiding component 28 includes a Y - direction guide frame 35, a Z - direction guide wheel 36, and a Y - direction guide wheel 37. Among them, two Y - direction guide frames 35 are provided. The two Y - direction guide frames 35 are symmetrically arranged on the inner side surfaces of the connecting rods 30 respectively, and one end of the Y - direction guide frame 35 extends out of the connecting rod 30 and bends along the side away from each other. The Y - direction guide frame 35 is used to position and guide the glue - applying trolley 4, reduce the operation difficulty, and avoid the collision between the glue - applying trolley 4 and the storage - location frame 22.

[0055] There are two sets of Z guide wheels 36, and the two sets of Z guide wheels 36 are symmetrically arranged on the upper surfaces of two connecting rods 30 respectively. Specifically, Z-direction connecting blocks 38 installed by bolts are arranged on the upper surfaces of the connecting rods 30, and the Z-direction connecting blocks 38 are arranged in a stepped shape. The Z guide wheels 36 are vertically rotatably arranged on the inner side surfaces of the Z-direction connecting blocks 38. Further, a Z-direction shim 39 for adjusting its horizontal height is arranged between the lower surface of the Z-direction connecting block 38 and the upper surface of the connecting rod 30. By adjusting the Z-direction shims 39 with different thicknesses, the horizontal heights of multiple said Z guide wheels 36 can be adjusted. Further, the top height of the Z-direction shim 39 is higher than the height of the guide rail 34;

[0056] There are two sets of Y guide wheels 37, and the two sets of Y guide wheels 37 are symmetrically arranged on the upper surfaces of two connecting rods 30 respectively. Specifically, a heightening seat 40 is arranged on the upper surface of the connecting rod 30, an installation plate 41 is arranged on the upper surface of the heightening seat 40, a Y-direction connecting block 42 is arranged on the upper surface of the installation plate 41, and the Y guide wheels 37 are horizontally rotatably arranged on the upper surface of the Y-direction connecting block 42;

[0057] Long circular holes 43 are arranged on both the Y-direction connecting block 42 and the installation plate 41. The opening direction of the long circular holes 43 is perpendicular to the arrangement direction of the connecting rods 30. Internal threads are arranged on the inner walls of the long circular holes 43, and fastening screws 44 that are in threaded fit with the internal threads are arranged;

[0058] Further, a long rod 45 fixed on the upper surface of the installation plate 41 is arranged outside the Y-direction connecting block 42. A horizontally arranged adjusting screw 46 is threadedly connected to the long rod 45. One side of the adjusting screw 46 can abut against the side end face of the Y-direction connecting block 42, and the adjusting screw 46 is preferably a fine-thread bolt; when adjusting the Y guide wheel 37, loosen the fastening screw 44, and by rotating the adjusting screw 46, the Y-direction connecting block 42 can be pushed inward to adjust the position of the Y-direction connecting block 42, or the adjusting screw 46 can be rotated outward, and the Y-direction connecting block 42 can be toggled outward to complete the adjustment of the position of the Y-direction connecting block 42.

[0059] Further, a first limiting block 48 is arranged at a position on the upper surface of the connecting rod 30 close to its cross bar 31, and a second limiting block 49 is arranged on the front surface of the glue application trolley 4;

[0060] The working principle of the present utility model is:

[0061] When gluing parts are required, the parts enter the gluing library position 5 through the Z guide wheel 36 and the Y guide wheel 37. After the first limit block 48 abuts against the second limit block 49, the positioning of the gluing trolley 4 is achieved. When the gluing trolley 4 is in place, the inductive coupling transmitter 26 and the inductive coupling receiver 21 that are wirelessly connected are coupled to energize the trolley detection sensor 33 and the part detection sensor 20. In the present utility model, the setting of the inductive coupler avoids the cable connection between the part detection sensor 20 on the gluing trolley 4 and the PLC control cabinet 3;

[0062] When the gluing trolley 4 is in place, the trolley detection sensor 33 identifies the number and position on the gluing trolley 4 to identify the number of the gluing trolley 4. Gluing trolleys 4 with different numbers are used for different types of parts or different production processes. Identifying the trolley number first helps reduce the risk of matching parts with incorrect production tasks. In addition, the number of the gluing trolley 4 is associated with a specific production task or part type. By identifying the trolley number, the control system can quickly determine the production task and the required operation procedure.

[0063] After the number of the gluing trolley 4 is completed, the PLC control cabinet 3 transmits a signal to the valve island 25, and the valve plate on the valve island 25 acts to start the clamping cylinder 23, and the clamping cylinder 23 clamps and fixes the gluing trolley 4;

[0064] Then, the part detection sensor 20 detects whether there are parts on the gluing trolley 4. If so, all the information of the parts to be glued has been obtained, and the PLC transmits this signal to the robot, and the robot retrieves the program of the parts to be glued to complete the gluing operation.

[0065] Refer to Figure 10 , in this embodiment, the number of the gluing trolley 4 is closely related to the trolley number identification plate 13 on the gluing trolley 4. By setting the trolley number identification plate 13 at 4 different numbers and positions ( Figure 10 represented by ABCD), the number of the trolley is judged.

[0066] Figure 10 In, the gray color indicates the position where the trolley number identification plate 13 exists. In this example, the types of the gluing trolleys 4 do not exceed 15, so the trolley number identification plate 13 is set at 4 different positions. If there are more types of the gluing trolleys 4, the number of digits of the trolley number identification plate 13 can be increased to realize the identification of more types of the gluing trolleys 4.

[0067] The relationship between the gluing trolley 4 and the trolley number identification plate 13 is: where m is the maximum identification quantity of the gluing trolley 4, and n is the number of the trolley number identification plates 13.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
