And during the actual dispensing process of the controller housing, a positioning fixture is usually required to position and limit the dispensing area of the controller housing;

[0003] In the existing dispensing positioning tooling, the dispensing positioning tooling mainly drives two sets of pressing plates to approach each other through an external driving force to position and clamp the controller housing;

[0004] However, during the actual use of the dispensing positioning tooling, after the controller housing is placed on the moving table, the controller housing is clamped and positioned by two sets of pressing plates. However, the two sets of pressing plates only clamp and position the two ends of the controller housing, and the two sides of the controller housing may not be completely on the dispensing machine tray (as shown in Figure 1 ), resulting in the situation that the center of gravity of the controller housing is unstable and tilts, and affecting the subsequent dispensing operation of the controller housing. Therefore, a positioning fixture for dispensing on the door controller housing is needed to solve the above problems;

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0022] As Figure 1 shown, the present application provides a positioning fixture for glue dispensing of a door controller housing, including a workbench 1 and a three-axis drive mechanism 11 installed on the workbench 1. A glue dispensing mechanism 2 is installed on the three-axis drive mechanism 11. The glue dispensing mechanism 2 is used for glue dispensing on the controller housing. The glue dispensing mechanism 2 includes a glue dispensing head 22 installed on the three-axis drive mechanism 11, and a feeding end 21 is provided on the glue dispensing head 22. The feeding end 21 is externally connected with a conveying pipe (not shown in the figure), the conveying pipe is externally connected with a glue storage tank, and the conveying pipe is adapted to convey the glue in the glue storage tank to the glue dispensing head 22 through an external driving force. And the three-axis drive mechanism 11 is adapted to drive the glue dispensing head 22 to move along three axes on the workbench 1 and perform welding operations on metal parts in the clamping area;

[0023] In the present application, both the glue dispensing mechanism 2 and the three-axis drive mechanism 11 are prior arts. For their specific structures and principles, please refer to the patent with the publication number CN219850444U, and no more details will be described here;

[0024] As Figure 2 - Figure 3 shown, a clamping mechanism 3 is installed on the workbench 1. The clamping mechanism 3 is used for positioning and fixing the controller housing. The clamping mechanism 3 includes a base 31 and two groups of slide tables 33 slidably installed on the base 31. A support table 321 for placing the controller housing is fixed at the center of the base 31. The support table 321 is above the base 31, and clamping plates 331 for abutting against the controller housing are provided at opposite ends of the two groups of slide tables 33. The two groups of slide tables 33 are adapted to slide on the base 31 and drive the two groups of clamping plates 331 to approach or move away from each other;

[0025] A gear 32 is installed on a bearing at the bottom end of the support 321. The support 321 and the gear 32 are concentrically arranged, and a motor (not shown in the figure) is connected to the center of the gear 32. The motor is at the bottom of the base 31 and is suitable for driving the gear 32 to rotate. Racks 34 are meshed on both sides of the gear 32. Two groups of racks 34 are respectively fixed on two groups of slides 33 and are arranged diagonally. When the controller housing needs to be positioned, the controller housing is first placed on the support 321, and the motor drives the gear 32 to rotate. Under the mutual cooperation of the gear 32 and the rack 34, the two groups of slides 33 approach each other, and indirectly drive the clamping plate 331 to approach to clamp and position the controller housing, thereby achieving the purpose of positioning controller housings of different sizes.

[0026] The two sets of slides 33 are both provided with limit units 4, and the two sets of limit units 4 are arranged opposite to each other. The slides 33 are also provided with a vertical plate 332, and the limit units 4 are arranged on the vertical plate 332. The two sets of limit units 4 are suitable for relative movement under external drive.

[0027] The limiting unit 4 includes a cylinder 41 slidably mounted on the vertical plate 332, and a pressure block 43 rotatably mounted on the output end of the cylinder 41. The pressure block 43 is suitable for rotating on the output end of the cylinder 41. A connecting rod 42 is provided at one side of the output end of the cylinder 41. Both ends of the connecting rod 42 are hinged to one side of the output end of the cylinder 41 and the middle section of the pressure block 43 to limit the rotation of the pressure block 43.

[0028] The pressing block 43 has a pressing end, on which a rubber sheet is arranged, and the rubber sheet contacts the controller housing to prevent the pressing block 43 from causing damage to the controller housing;

[0029] When the output end of the cylinder 41 is extended and retracted, the output end of the cylinder 41 drives the end of the pressing block 43 to move, and the pressing block 43 is tilted under the cooperation of the pressing block 43 and the connecting rod 42, so that the tilt angle of the pressing block 43 is completely matched with the inclined surface of the controller housing, thereby achieving the purpose of adjusting the tilt angle of the pressing block 43;

[0030] When the two groups of clamping plates 331 are limiting the position of the controller housing, the two groups of cylinders 41 slide on the vertical plates 332 under the action of external drive, and after the cylinders 41 move to the diagonal positions of the controller housing, the positions of the cylinders 41 are fixed, and the cylinders 41 operate at the same time, and through the cooperation of the connecting rods 42, the pressing blocks 43 are driven to rotate and contact the controller housing, so as to apply downward pressure to the diagonal positions of the controller housing, thereby achieving the purpose of limiting the upper and lower positions of the top inclined surfaces of different controller housings and preventing the center of gravity of the controller housing from shifting;

[0031] In summary, through the rotation of the gear 32 and in cooperation with the rack 34, the two sets of vertical plates 332 are adapted to approach or move away from each other to clamp the controller housing. At the same time, driven by the two sets of cylinders 41, the pressing block 43 moves, and in cooperation with the connecting rod 42, the pressing block 43 rotates and abuts against the top edge of the controller housing, thereby achieving the purpose of upper and lower limits for the top inclined surface of different controller housings and solving the problem of unstable positioning center of gravity and inclination at both ends of the controller housing.

[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any improvements and refinements made within the spirit and principle of the present application and without departing from the principle of the present application should also be considered within the protection scope of the present application.
