Technical Field

[0001] This invention belongs to the technical field of lobster processing equipment, specifically a positioning device for separating the head and tail of lobsters. Background Technology

[0002] Crayfish tails are an important processed product of crayfish. Due to the lack of related processing equipment, crayfish tails are all separated manually. Due to the seasonality of crayfish harvesting, high worker turnover, rising labor costs, and decreasing number of workers of working age, there is a labor shortage problem in the crayfish tail separation process. In addition, manual separation is also characterized by high labor intensity and low efficiency. Therefore, in order to promote the development of the industry and reduce the amount of labor required for crayfish processing, a positioning device for separating crayfish heads and tails is being developed. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a positioning device for separating the head and tail of lobsters, which effectively solves the problem of low work efficiency caused by the existing manual separation of lobsters.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for separating the head and tail of a lobster, comprising a support base, a support frame fixedly mounted on the top of the support base, a feeding conveyor belt mounted on one end of the top of the support frame, a distributing conveyor belt, five directional conveyor belts and a lobster tail discharge conveyor belt mounted on the top of the support base, the distributing conveyor belt being located at one end of the bottom of the feeding conveyor belt, the directional conveyor belt being located at one end of the distributing conveyor belt away from the feeding conveyor belt, and the lobster tail discharge conveyor belt being located at the bottom of the distributing conveyor belt and the directional conveyor belt, and a pop-out mechanism, a correction mechanism, five turning mechanisms, five auxiliary pushing mechanisms, five lobster tail pressing mechanisms and five lobster head pulling out mechanisms being sequentially mounted on the top of the support frame from the distributing conveyor belt to the directional conveyor belt, the five turning mechanisms being staggered, and a controller being fixedly mounted on one end of the top of the support frame;

[0005] The correction mechanism consists of a hanging plate and four diversion plates. The hanging plate is fixedly connected to the top of the support frame, and the four diversion plates are fixedly connected to the bottom of the hanging plate. The diversion plates divide the top of the material distribution conveyor belt into five channels. After the lobster comes into contact with the diversion plate, it automatically corrects its direction so that the lobster is parallel to the direction of movement of the material distribution conveyor belt.

[0006] The turning mechanism consists of a cylinder, a clamping assembly, and a vision camera. The clamping assembly is fixedly connected to the bottom of the cylinder, and the vision camera is fixedly connected to one side of the clamping assembly. The vision camera identifies the direction of the lobster. If the tail of the lobster is facing forward, the clamping assembly will turn the lobster 180 degrees.

[0007] The shrimp tail clamping mechanism consists of a second cylinder, an arc-shaped pressure plate, and a second vision camera. The arc-shaped pressure plate is fixedly connected to the bottom of the second cylinder, and the second vision camera is fixedly connected to the bottom of one side of the second cylinder. The second vision camera identifies the position of the lobster, and the second cylinder drives the arc-shaped pressure plate to press down, thereby clamping and fixing the tail of the lobster.

[0008] The shrimp head pulling mechanism consists of a U-shaped support frame, a cylinder three, and a clamping component two. The cylinder three is fixedly connected to the bottom end of the U-shaped support frame, and the clamping component two is slidably connected to the bottom end of the U-shaped support frame and fixedly connected to the cylinder three. The clamping component two clamps the lobster head, and the cylinder three drives the clamping component two to move, separating the lobster head from the lobster tail.

[0009] Both clamping components one and two consist of a motor mounting bracket, a servo motor one, a rotating support frame, a cylinder four, a slider, a fixed clamping plate, and a movable clamping plate. The servo motor one is fixedly connected inside the motor mounting bracket, the rotating support frame is fixedly connected to the output shaft of the servo motor one, the cylinder four is fixedly connected inside the rotating support frame, the slider is slidably connected inside the rotating support frame and fixedly connected to the cylinder four, the fixed clamping plate is fixedly connected to the rotating support frame, and the movable clamping plate is fixedly connected to the slider. The cylinder four can drive the slider to move, and the slider drives the movable clamping plate to move. The lobster is clamped by the fixed clamping plate and the movable clamping plate. The servo motor one drives the rotating support frame to rotate, which can turn the lobster in the opposite direction, or facilitate the separation of the lobster head and tail by reciprocating small-amplitude rotation.

[0010] Preferably, several casters are fixedly installed on both sides of the bottom end of the support base, which facilitates the movement of the device.

[0011] Preferably, one end of the support base is provided with a shrimp tail receiving box, and the top end of the support base is provided with a shrimp head receiving box located at the bottom of the shrimp head pulling mechanism, which can receive the separated shrimp tail and shrimp head respectively.

[0012] Preferably, strip-shaped limiting baffles are fixedly installed on both sides of the top end of the directional conveyor belt to limit the lobster and prevent it from falling.

[0013] Preferably, one end of the diverter plate has a flat-head structure, which can avoid obstructing the lobster and affecting the correction efficiency of the lobster.

[0014] Preferably, a limiting rod is fixedly installed inside the U-shaped support frame, and the top end of the clamping component two is sleeved on the limiting rod and slidably connected to the limiting rod. The limiting rod is used to assist in limiting the clamping component two and improve stability.

[0015] Preferably, the ejection mechanism consists of a strip-shaped hanging plate, a second servo motor, and a strip-shaped push plate. The second servo motor is fixedly connected to the bottom end of one side of the strip-shaped hanging plate, and the strip-shaped push plate is located at the bottom end of the other side of the strip-shaped hanging plate and is fixedly connected to the output shaft of the second servo motor. When the lobster is horizontally stuck at one end of the diverter plate, the second servo motor drives the strip-shaped push plate to rotate, thus pushing the lobster out and adjusting its position.

[0016] Preferably, the width of the strip pusher is smaller than the distance between two adjacent diverter plates, which allows the strip pusher to move between two adjacent diverter plates and avoids obstruction.

[0017] Preferably, the auxiliary pushing mechanism consists of a cylinder five, a hanger, a vision camera three, a servo motor three, and three rotating pushing plates. The hanger is fixedly connected to one end of the cylinder five, the vision camera three is fixedly connected to the bottom end of one side of the hanger, the servo motor three is fixedly connected to the bottom end of the other side of the hanger, and the rotating pushing plates are all fixedly connected to the output shaft of the servo motor three. During the lobster separation process, the directional conveyor belt is in a stationary state. If the lobsters on the distribution conveyor belt continue to be transported to the directional conveyor belt, the rotating pushing plates will drive the lobsters to slide on the directional conveyor belt, thus preventing the lobsters from accumulating.

[0018] Preferably, the width of the rotating pusher plate is smaller than the width of the directional conveyor belt.

By setting up clamping component 1 and clamping component 2 consisting of motor mounting frame, servo motor 1, rotating support frame, cylinder 4, slider, fixed clamping plate and moving clamping plate, the lobster can be clamped when the lobster is turned in the opposite direction. When the shrimp tail and shrimp head are separated, the shrimp head can be driven to rotate back and forth to improve the smoothness of separation.

[0023] (4) By setting up a pop-out mechanism consisting of a strip-shaped hanging plate, a servo motor II and a strip-shaped push plate, the lobster can be pushed out when it is stuck laterally at one end of the diverter plate, thereby adjusting the position of the lobster. By setting up an auxiliary pushing mechanism consisting of a cylinder V, a hanger, a vision camera III, a servo motor III and three rotating pushing plates, the lobster can be driven to slide on the directional conveyor belt to avoid lobster accumulation.
