[0026] The following is a detailed description of a bidirectional locking device for a feeding trolley provided in an embodiment of the present invention, with reference to the accompanying drawings.

[0027] Example:

[0028] Figure 1 This diagram shows a three-dimensional structural schematic of the bidirectional locking device for the feeding trolley provided in an embodiment of the present invention. Figure 2 It shows Figure 1 Enlarged view of part A in the middle; Figure 3 This shows a front view of the bidirectional locking device for the feeding trolley provided in an embodiment of the present invention; Figure 4 A top view of the bidirectional locking device for the loading trolley provided in an embodiment of this utility model is shown. Figures 1 to 4As shown in the figure, this utility model provides a bidirectional locking device for a loading trolley, which is used to realize the locking and releasing actions of the loading trolley in two position states at the workstation. It has good safety, high degree of automation, and facilitates various operations on the workpieces on the loading trolley in automated production lines. The bidirectional locking device for a loading trolley provided in this utility model includes: a mounting base plate 1, a guide mechanism 2, a locking mechanism, a positioning component, at least four support rollers 9, and a valve island assembly 11. The guide mechanism 2, locking mechanism, positioning component, support rollers 9, and valve island assembly 11 are all arranged above the mounting base plate 1 and are mechanically connected to the mounting base plate 1 to realize the installation and fixation of the above components. Specifically, the guide mechanism 2 includes a first guide plate 201 and a second guide plate 202. The first guide plate 201 and the second guide plate 202 are arranged parallel to each other on the mounting base plate 1 to realize the movement of the loading trolley in and out of the workstation. The guiding function, by pushing the guide rods or guide wheels on the loading trolley into the area between the first guide plate 201 and the second guide plate 202, can limit the excessive positional deviation of the loading trolley, position the loading trolley, and ensure that the loading trolley can only move in a straight line along the guide mechanism 2, so that the loading trolley enters the work station from left to right from the mounting base plate 1 and finally locks in place; more specifically, one end of the first guide plate 201 is provided with a first guide part 20101, and one end of the second guide plate 202 is provided with a second guide part 20201. The angle between the first guide part 20101 and the second guide part 20201 is V-shaped to guide the loading trolley into the work station. The V-shaped opening formed by the first guide part 20101 and the second guide part 20201 is more conducive to guiding the loading trolley into the work station and avoids the loading trolley from bumping and jamming due to positional deviation. Several support rollers 9 are evenly distributed on the mounting base plate 1 to support the loading trolley and reduce the movement resistance when pushing it into the work station. In this embodiment, four support rollers 9 are used, which are respectively set below the loading trolley and evenly distributed to facilitate the smooth pushing of the loading trolley into the work station. Of course, more than four support rollers 9 can be set according to user needs, such as six, eight, etc. The number of support rollers 9 is not specifically limited here. The valve island assembly 11 is connected to the locking mechanism to control the locking and releasing action switching of the locking mechanism; at least one locking mechanism and positioning component are respectively set at both ends of the mounting base plate 1 to realize locking and positioning of the loading trolley in at least two placement states; specifically, the two states of the loading trolley can be understood as, in Figure 3 For example, the right end of the loading trolley is... Figure 3 When the right end of the mounting base plate 1 corresponds to the position of the loading trolley, the first locking mechanism 3 in the locking mechanism, the first positioning component 5 in the positioning component, and the first sensor 7 play corresponding roles on the loading trolley; when the right end of the loading trolley is aligned with... Figure 3When the left end of the mounting base plate 1 corresponds to another position state of the loading trolley, the second locking mechanism 4 in the locking mechanism, the second positioning component 6 in the positioning component, and the second sensor 8 play corresponding roles on the loading trolley.

[0029] In a bidirectional locking device for a loading trolley according to an embodiment of this utility model, the locking mechanism further includes: a first locking mechanism 3 and a second locking mechanism 4. The first locking mechanism 3 is disposed at one end of the mounting base plate 1 and is mechanically connected to the mounting base plate 1. The first locking mechanism 3 is connected to the valve island assembly 11 to realize locking and releasing actions on the loading trolley in a certain placement state. That is, the first locking mechanism 3 is used to lock or release the right end of the loading trolley. At this time, the right end of the loading trolley is... Figure 3 The right end of the mounting base plate 1 corresponds to the position of the loading trolley, at which point the loading trolley is fully in the working position. The second locking mechanism 4 is located at the other end of the mounting base plate 1 and is mechanically connected to the mounting base plate 1. The second locking mechanism 4 is connected to the valve island assembly 11 to realize the locking or releasing action of the loading trolley in another placement state; that is, the second locking mechanism 4 is used to lock or release the right end of the loading trolley, at which point the right end of the loading trolley is aligned with the valve island assembly 11. Figure 3 The position of the mounting base plate 1 shown in the figure corresponds to the left end position. At this time, the loading trolley is in the state of just entering the work station (or the loading trolley is not completely leaving the work station). At this time, there are corresponding locking mechanisms for both positions of the loading trolley to prevent unexpected movement of the loading trolley in the two positions and improve the safety of the equipment.

The control system in the production line controls the valve island assembly 11 to perform corresponding control actions to control the gas supply in the air circuit, thereby achieving the purpose of controlling the cylinders in the first locking mechanism 3 and the second locking mechanism 4 to perform actions. The first locking mechanism 3 and the second locking mechanism 4 are both driven by cylinders, which take advantage of the characteristics of cylinders being fast and economical. The cylinders drive the opening and closing actions of the pressure rods on the first locking mechanism 3 and the second locking mechanism 4, thereby clamping and releasing the frame at the corresponding position on the loading trolley, realizing the locking and fixing of the loading trolley position.

Figure 3 When the right end of the mounting base plate 1 shown corresponds to the position of the loading trolley, the position is limited, improving the positioning accuracy of the loading trolley. At this time, the loading trolley is fully in the working position, and the right end of the mounting base plate 1 is located below the right end of the loading trolley. The second positioning component 6 is set at the other end of the mounting base plate 1 and is mechanically connected to the mounting base plate 1. The second positioning component 6 is mechanically connected to the loading trolley to realize the position positioning of the loading trolley in another placement state, that is, the right end of the loading trolley is aligned with the right end of the loading trolley. Figure 3 When the left end of the mounting base plate 1 is positioned corresponding to the position of the loading trolley, the position of the loading trolley is limited, improving the positioning accuracy of the loading trolley. At this time, the loading trolley is just entering the workstation, and the left end of the mounting base plate 1 is located below the right end of the loading trolley. Preferably, the installation height and installation position of the first positioning component 5 and the second positioning component 6 on the mounting base plate 1 can be adjusted to improve versatility and applicability, avoid positional interference to the loading trolley entering and leaving the workstation, and adapt to loading trolleys of various specifications.

Figure 3 The first sensor 7 and the second sensor 8 are mechanically connected to the left end of the mounting base plate 1 to achieve status recognition of the loading trolley in another placement state. By utilizing the first sensor 7 and the second sensor 8, the automation and intelligence of the bidirectional locking device of the loading trolley can be improved, realizing the position status recognition of the loading trolley, further improving work safety and preventing malfunctions. Preferably, the first sensor 7 and the second sensor 8 can be configured as proximity switches, making full use of the wide application, fast response, and economic advantages of proximity switches. Furthermore, the installation height and installation position of the first sensor 7 and the second sensor 8 on the mounting base plate 1 can be adjusted to improve versatility and applicability, avoid positional interference to the loading trolley entering and leaving the workstation, and adapt to loading trolleys of various specifications.

[0033] In a bidirectional locking device for a loading trolley according to an embodiment of this utility model, as a further design improvement, it further includes: a buffer assembly 10.
