Referring to fig. 1 to 5, the present invention provides a battery production apparatus (not shown) and a positioning device 10, wherein the battery production apparatus includes the positioning device 10. The positioning device 10 can be applied to each process of the battery production equipment in cooperation with a corresponding conveying line. The conveyor line can convey workpieces required by the process to a designated station, and the positioning device 10 can position a plurality of workpieces in the same batch on the conveyor line, so that the corresponding process can smoothly perform batch processing.

Such as: the positioning device 10 can be applied to the cap feeding module in the battery production equipment, and a batch of support cups for bearing the caps can enter a feeding station under the conveying of the conveying line. Next, the positioning device 10 positions the plurality of cups in the same batch so as to be arranged in a regular manner.

So, battery unloading mechanism alright follow a plurality of trays simultaneously and absorb the battery accurately and realize unloading sabot.

Referring to fig. 1 and 2, a positioning device 10 in a preferred embodiment of the utility model includes a material stop mechanism 100, a positioning mechanism 200, and a base 300.

The base 300 serves as a support and may be a metal plate-like structure. Both the striker 100 and the positioning mechanism 200 can be mounted on the base 300. In other embodiments, the base 300 may be omitted, and the material blocking mechanism 100 and the positioning mechanism 200 may be directly mounted on the worktable or the frame of the battery production equipment.

The positioning device 10 is formed with a positioning area (not shown) through which a transfer line for transferring the work in the first direction can pass. Therefore, the conveying line can convey a plurality of workpieces to the positioning area and be positioned. The positioning area generally overlaps with the designated station, such as the feeding station and the discharging station, at least partially, and the workpiece can be positioned at the designated station by positioning the workpiece at the positioning area.

The positioning area is provided with a feeding end and a discharging end, and workpieces can enter the positioning area from the feeding end along with the conveying line and can be discharged from the positioning area from the discharging end along with the conveying line. The feeding end and the discharging end of the positioning area are arranged at intervals in a first direction, the first direction in the embodiment refers to the left-right direction shown in fig. 1, the feeding end is located on the left side shown in fig. 1, and the discharging end is located on the right side shown in fig. 1.

The material stop mechanism 100 is arranged at the feeding end and the discharging end of the positioning area. That is to say, there are at least two stock stops 100, and the feed end and the discharge end should be provided with at least one stock stop 100. The striker 100 has a blocking state and an avoiding state. The material blocking mechanism 100 in the blocking state can prevent the workpieces from being conveyed along the conveying line; the stock stop 100 in the avoiding state allows the workpiece to be conveyed along with the conveying line.

Specifically, when the material blocking mechanism 100 is switched to the blocking state, the workpiece conveyed along the conveying line can be blocked. At this time, the conveyor line continues to run and the workpiece is stopped, so that relative motion is generated between the workpiece and the conveyor line. When the material blocking mechanism 100 is switched to the avoiding state, the workpiece conveyed along with the conveying line can be released, so that the workpiece can move synchronously along with the conveying line.

The number of the workpieces entering the positioning area can be controlled by controlling the state of the material blocking mechanism 100 at the feeding end; the number of workpieces discharged from the positioning area can be controlled by controlling the state of the material stop mechanism 100 at the discharge end. Therefore, the quantity of the same batch of workpieces in the positioning area can be accurately controlled, and the requirements of corresponding processes are met.

The positioning mechanism 200 includes a positioning driving member 210 and a positioning plate 220, and a plurality of positioning slots 221 are formed on the positioning plate 220 at intervals. The positioning driving member 210 may be an air cylinder, and the positioning plate 220 may be a long strip-shaped metal plate or a plastic plate. The positioning driving unit 210 can drive the positioning plate 220 to move to a position where the plurality of workpieces located in the positioning area are respectively clamped into the plurality of positioning slots 221.

When the quantity of work piece in the location area satisfies the demand, the stock stop 100 of feed end and discharge end all switches to the block state to restrict a plurality of work pieces in the location area. Then, the positioning driving unit 210 can drive the positioning plate 220 to move toward the workpiece in the positioning area until contacting the workpiece. The positioning slots 221 are arranged on the positioning plate 220 according to a certain rule. Therefore, when a plurality of workpieces are respectively clamped into the plurality of positioning clamping slots 221, the same batch of workpieces will be positioned and arranged according to a certain rule.

In order to enable the workpiece to be smoothly clamped into the positioning clamping grooves 221, a comb-shaped structure is formed between every two adjacent positioning clamping grooves 221. The comb-shaped structure can be inserted into the gap between two adjacent workpieces, and can play a role in guiding, so that the workpieces can slide into the positioning clamping groove 221.

Specifically, in the present embodiment, the positioning plate 220 is slidably disposed on the base 300 through a wire rail 310 and a slider (not shown), and the wire rail 310 extends along a second direction perpendicular to the first direction.

Specifically, the second direction refers to the up-down direction shown in fig. 1. At this time, the positioning plate 220 extends along the first direction, and a plurality of positioning slots 221 are also disposed on the positioning plate at intervals along the first direction. Two wire rails 310 may be provided, and the positioning driver 210 may be disposed between the two wire rails 310. Under the driving of the positioning driving member 210, the positioning plate 220 can approach or depart from the positioning area in the second direction to complete the positioning operation. Moreover, the positioning plate 220 has higher stability in the moving process.

In the present embodiment, the driving end of the positioning driving element 210 is elastically connected to the positioning plate 220, so that the positioning plate 220 can elastically abut against a plurality of workpieces located in the positioning area. Therefore, when the positioning driving member 210 drives the positioning plate 220 to position the workpiece in the positioning area, a buffering effect can be achieved, so that the positioning plate 200 is prevented from being damaged due to hard contact with the workpiece to be positioned.

Further, in the present embodiment, the positioning mechanism 200 further includes a driving block 230, a driving shaft 240 and an elastic member 250. The driving block 230 is fixed to the positioning plate 220, the driving shaft 240 is fixed to the driving end of the positioning driving member 210 and slidably penetrates through the driving block 230, the elastic member 250 is sleeved on the driving shaft 240, and two ends of the elastic member respectively abut against the driving block 230 and the driving shaft 240.

The driving block 230 may be fixed to the positioning plate 220 by welding or screw fastening, and the positioning driving member 210 transmits power to the driving block 230 through the driving shaft 240, thereby driving the positioning plate 220 to move in the second direction. When the positioning plate 220 abuts against the workpiece, the elastic member 250 elastically compresses and the positioning plate 220 retracts. Thus, the elastic contact with the workpiece can be realized. Generally, the elastic member 250 is a spring, which has a simple structure and is easy to install.

Specifically, in this embodiment, the striker 100 is mounted on the base 300 through the movable mounting plate 400, and the movable mounting plate 400 enables the striker 100 to be adjustable in position in a first direction and a second direction perpendicular to the first direction.

The position of the material blocking mechanism 100 is adjusted along the first direction and the second direction, so that the relative position of the material blocking mechanism 100 and the conveying line can be adjusted, the material blocking mechanism 100 can be suitable for a scene of blocking materials for workpieces of different models, and the application range of the positioning device 10 is further enlarged.

Specifically, the movable mounting plate 400 includes a first adjusting plate 410 and a second adjusting plate 420. The material stop mechanism 100 is installed on the first adjusting plate 410, and the first adjusting plate 410 is installed on the second adjusting plate 420 and can perform position adjustment along the second direction relative to the second adjusting plate 420. The second adjustment plate 420 is mounted to the base 300 and is capable of position adjustment in a first direction relative to the base 300. The installation between the first adjusting plate 410 and the second adjusting plate 420 and between the second adjusting plate 420 and the base 300 can be realized through the matching of the strip-shaped holes and the threaded fasteners, so that the position adjustment is realized.

The stop and release of the workpiece can be realized by the material blocking mechanism 100 in various modes, and the structures of the material blocking mechanisms 100 positioned at the feeding end and the discharging end can be the same or different. Such as:

referring to fig. 3 to 5 again, in one embodiment, the material stop mechanism 100 at the feeding end includes a first driving member 110 and a blocking member 120.

The first actuator 110 may be an air cylinder, an electric cylinder, or the like, and the blocking member 120 may be a stopper, a baffle, or a rod-like structure. The blocking member 120 is installed at a driving end of the first driving member 110, and the first driving member 110 can drive the blocking member 120 to extend into or move out of a conveying path of the conveying line so as to drive the material blocking mechanism 100 to switch between a blocking state and an avoiding state.

When the blocking member 120 extends into the conveying path of the conveying line, the blocking member 120 can block the workpiece conveyed along with the conveying line, and the material blocking mechanism 100 is switched to the blocking state; when the blocking member 120 moves out of the conveying path of the conveying line, the blocking member 120 can yield the workpiece conveyed along with the conveying line, and the material blocking mechanism 100 is switched to the yielding state. The material blocking mechanism 100 is simple in structure, convenient to control and low in cost.

Further, the material stopping mechanism 100 at the discharging end includes a rotating disc 130, an engaging element 140, a second driving element 150 and a limiting element 160.

Referring to fig. 1 and fig. 2 again, in another embodiment, the material stop mechanism 100 at the feeding end and the discharging end includes a rotating disc 130, a fitting element 140, a second driving element 150, and a limiting element 160.

The turntable 130 is rotatably provided. Specifically, the turntable 130 may be rotatably mounted on the base 300 by a rotating shaft (not shown), and the rotating shaft is perpendicular to the carrying surface of the conveyor line. A plurality of limiting grooves 131 are formed along the periphery of the turntable 130, and the workpieces conveyed along the conveying line can sequentially enter the limiting grooves 131 and push the turntable 130 to rotate. Typically, each restraint slot 131 can generally accommodate only one workpiece. When a previous workpiece conveyed along the conveying line enters the limiting groove 131, the turntable 130 is pushed to rotate. After the turntable 130 rotates a certain angle, the previous workpiece will move out of the limiting groove 131, and the next workpiece can enter the next limiting groove 131. By analogy, a plurality of workpieces conveyed with the conveyor line will pass sequentially, one by one, past the turntable 130 to enter or exit the positioning area.

The number of the limiting grooves 131 is set according to the number of the workpieces to be positioned in each batch, for example, the number of the limiting grooves 131 in this embodiment is sixteen. Each revolution of the turntable 130 will cause sixteen workpieces to enter or exit the indexing zone.

The engaging member 140 is fixedly disposed on the rotating disc 130 and can move circularly with the rotating disc 130. The engagement members 140 may be a bar, a stop, or the like. The engaging member 140 is eccentrically disposed with respect to the rotation axis of the rotation disc 130, so that the movement locus of the engaging member 140 is circular.

The second driving member 150 may be an air cylinder, an electric cylinder, etc., and the limiting member 160 may also be a stop lever, a stopper, etc. The limiting member 160 is installed at the driving end of the second driving member 150, and the second driving member 150 can drive the limiting member 160 to extend into or avoid the motion track of the mating member 140.

Specifically, when the limiting member 160 extends into the motion track of the engaging member 140, the engaging member 140 will abut against the limiting member 160 along with the rotation of the rotating disc 130, so as to prevent the rotating disc 130 from further rotating. At this time, the striker 100 is in the blocking state. When the limiting member 160 avoids the motion track of the engaging member 140, the limiting member 160 does not block the engaging member 140, so that the rotating disc 130 can rotate freely. At this time, the striker 100 is in the retracted state.

Compared with the material stopping mechanism 100 at the feeding end in the previous embodiment, the rotary disc 130 in this embodiment only allows the workpieces to pass one by one, so that the conveying speed of the workpieces is reduced. Therefore, when the workpiece is stopped, the turntable 130 does not collide with the workpiece strongly and responds more timely, so that the number of workpieces can be controlled more accurately without causing damage to the workpieces.

When a batch of workpieces are positioned and conveyed to the next process, the material stop mechanism 100 at the feeding end can be switched to the avoiding state at the same time, so that the next batch of workpieces to be positioned enter the positioning area at the same time. That is to say, the discharge and entrance of the workpiece from the positioning area are performed synchronously, and the material blocking device 100 at the feeding end does not need to be switched to the avoiding state after the workpiece in the positioning area is emptied. Therefore, the processing efficiency can be remarkably improved.

Further, in the present embodiment, magnetic attraction can be achieved between the fitting element 140 and the limiting element 160.

When the engaging member 140 abuts against the limiting member 160, the engaging member 140 and the limiting member 160 are attracted to each other to prevent the rebounding caused by the collision, so that the reliability of the material blocking mechanism 100 can be improved. Specifically, a magnet 161 may be embedded in the limiting member 160, and the mating member 140 may be formed of a ferromagnetic material such as iron. Thus, when the engaging element 140 and the limiting element 160 are close to each other, the engaging element and the limiting element can be magnetically attracted.

Further, in the present embodiment, the material blocking mechanism 100 includes a proximity sensor 170, the proximity sensor 170 can be triggered when the engaging element 140 moves to the preset position, and the second driving element 150 drives the limiting element 160 to extend into the movement track of the engaging element 140 when the proximity sensor 170 is triggered.

In particular, the provision of the proximity sensor 170 can increase the degree of automation of the positioning device 10. The engaging member 140 typically triggers the proximity sensor 170 after the dial 130 has rotated one-half turn from the initial position, which refers to a position where the engaging member 140 can abut the stop member 150. Therefore, the accuracy of stopping the material by the material stopping mechanism 100 can be improved.

According to the positioning device 10 and the battery production equipment, the material stop mechanism 100 can be switched to the avoiding state firstly, so that the required number of workpieces enter the positioning area under the transmission of the conveying line. Then, the material stop mechanisms 100 at the feeding end and the discharging end are switched to the blocking state, so that the workpieces outside the positioning area cannot enter continuously, and the workpieces inside the positioning area cannot be discharged. The positioning driving element 210 acts until the plurality of workpieces in the positioning area are respectively clamped into the plurality of positioning clamping grooves 221, so that the plurality of workpieces in the positioning area can be positioned. The stock stop 100 enables a desired number of workpieces to be maintained stable within the positioning zone. Therefore, the positioning device 10 and the battery production equipment can accurately position a plurality of workpieces on the conveying line.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
