DETAILED DESCRIPTION

[0022] See also Figure 1-6 As shown, the technical solution adopted in this specific embodiment is: it comprises a tray 1, a positioning mechanism 2 is arranged at the bottom of the tray 1, a clamping mechanism 3 is arranged at the top of the tray 1, a transmission mechanism 4 is arranged below the front end of the clamping mechanism 3, and the lower part of the main body of the clamping mechanism 3 is connected to a guide rail 5 arranged on the tray 1. In this embodiment, the clamping mechanism performs the conveying operation of the assembly line through the transmission mechanism, and the clamping mechanism is rollingly connected to the guide rail to realize smooth movement on the tray;

[0023] Specifically, the clamping mechanism 3 includes a fixed bottom plate 3-1 and a positioning platform 3-2. The positioning platform 3-2 is arranged at the front end of the fixed bottom plate 3-1 and is located above the empty slot opened on the tray 1. When the clamping mechanism is transmitted, it needs to be located at the center of the tray for subsequent production operations. The fixed bottom plate is used to fasten the shoe last, and the positioning platform cooperates with the positioning mechanism to achieve positioning at the center of the tray.

[0024] A fixing groove 3-1-1 is provided on the fixing bottom plate 3-1. The fixing groove 3-1-1 is a U-shaped opening structure. The shape of the fixing groove matches the shape of the connector of the shoe last. When installing the shoe last, it is only necessary to put the shoe last connector roughly relative to the fixing groove, and the shoe last is limited and fixed by the fixing groove.

[0025] A marble groove 3-1-2 is provided at one side of the closed end of the front end of the fixing groove 3-1-1, and a positioning marble 3-8 is provided in the marble groove 3-1-2. A strong magnet and a positioning hole are provided on the shoe last connector. When the shoe last connector is connected to the fixing groove, the positioning marble will bounce into the positioning hole, which not only plays a positioning role, but also makes a mechanical sound, so as to confirm whether the shoe last is installed in place.

[0026] Fastening blocks 3-3 are arranged on both sides above the fixing groove 3-1-1. In this embodiment, the fixing groove fixes the shoe last connector, and the fastening blocks clamp and fix the shoe last from both sides. In this embodiment, the U-shaped fixing groove realizes semi-enclosed three-dimensional fixation, the fastening blocks strengthen the fastening from both sides, and the positioning marbles realize the positioning in the same direction as the opening of the fixing groove. The multi-dimensional fastening method can better fix the shoe last;

[0027] A clamping plate 3-5 is provided at the bottom of the positioning platform 3-2, and the clamping plate 3-5 is connected to the transmission mechanism 4. The clamping plate 3-5 is a U-shaped structure, including a frame 3-51 and a driven plate 3-52. The driven plate 3-52 is arranged in the frame 3-51, and the tops of the two are connected to the bottom of the positioning platform 3-2 by bolts. In this embodiment, the driven plate is a rubber plate, and the transmission mechanism is a belt transmission mechanism. When the belt passes through the frame, it is compressed by the driven plate, thereby driving the clamping mechanism to move. In another embodiment, the transmission mechanism is a chain transmission mechanism, and the driven plate is a toothed plate structure, which can be selected according to different production needs.

[0028] More specifically, a positioning iron sheet 3-7 is provided in the fixing groove 3-1-1. Since a strong magnet is provided on the shoe last connector, the strong magnet is attracted to the positioning iron sheet, so that the shoe last can be fixed in the vertical direction.

[0029] To be more specific, a tightening spring 3-6 is also provided at the bottom of the positioning platform 3-2. The tightening spring 3-6 passes through the frame 3-51 and abuts against the driven plate 3-52. Through the action of the tightening spring on the driven plate, the driven plate can be better tightened to ensure close contact with the transmission belt and ensure the driving effect.

[0030] To be more specific, four guide wheels 3-4 are arranged at the bottom of the fixed base plate 3-1, guide grooves are opened on the guide wheels 3-4 to match the guide rails 5, and the guide wheels 3-4 are rollingly connected with the guide rails 5. In this embodiment, V-shaped limiting structures matching the guide grooves on the guide wheels are arranged on both sides of the guide rails, so that the guide wheels are clamped with the guide rails and will not shake or loosen during the movement of the clamping mechanism.

[0031] More specifically, the positioning mechanism 2 includes a positioning cylinder 2-1, a connecting rod 2-2, a rotating shaft 2-3, a positioning plate 2-4, and a positioning shaft seat 2-6. The end of the positioning cylinder 2-1 is movably connected to a cylinder seat 2-7, and the cylinder seat 2-7 is fixed to the bottom of the tray 1. The connecting rod 2-2 is arranged at the front end of the cylinder push rod of the positioning cylinder 2-1. There are two positioning shaft seats 2-6, which are symmetrically arranged at the bottom of the tray 1. The bearing of the rotating shaft 2-3 is connected to the positioning shaft seat 2-6, and the top of the connecting rod 2-2 is fixed to the rotating shaft 2-3. The bottom of the positioning plate 2-4 is fixed on the rotating shaft 2-3. In the present embodiment, the positioning mechanism is a connecting rod mechanism. The existing clamps are generally positioned manually or by induction of sensors. The positioning by manual operation based on experience is not accurate enough, and positioning by sensors not only increases the cost, but also increases the maintenance cost. When positioning is performed by a connecting rod mechanism, the positioning plate is inserted into the U-shaped groove in the positioning table to tighten the clamping mechanism, and the position of the clamping mechanism can be adjusted while tightening to achieve precise positioning. The structure is simple and the equipment cost is low.

[0032] More specifically, a positioning roller 2-5 is provided on the top of the positioning plate 2-4, and a U-shaped groove is provided at the front end of the positioning platform 3-2. The U-shaped groove matches the positioning roller 2-5, and the positioning roller can slide into the U-shaped groove better when in contact with the positioning platform, thereby achieving precise positioning.

[0033] The working principle of the utility model is as follows: the shoe last 6 is hoisted above the clamping mechanism 3, the shoe last 6 is lowered and placed in the fixing groove 3-11, since the shoe last 6 is provided with a strong magnet and a positioning hole, the strong magnet is attracted to the positioning iron sheet 3-7, and at the same time, the positioning marble 3-8 is ejected into the positioning hole to limit the shoe last, and the two fastening blocks 3-3 fasten the two sides of the shoe last. The installation and fixing of the entire shoe last 6 is simple and fast. When the shoe last 6 is installed, the transmission mechanism 4 is started, and the transmission mechanism 4 is matched with the driven plate 3-52. The clamping mechanism 3 is closed, driving the clamping mechanism 3 to move. When the clamping mechanism 3 reaches the middle of the tray 1, it stops and starts the positioning cylinder 2-1, pushing the connecting rod 2-2 to drive the rotating shaft 2-3 to rotate, so that the positioning plate 2-4 rotates synchronously and snaps into the U-shaped groove of the positioning platform 3-2. Since a positioning roller 2-5 is provided on the top of the positioning plate 2-4, it can easily enter the U-shaped groove. When the position of the clamping mechanism does not reach the specified position, it will move under the action of the positioning plate 2-4 for precise positioning.

[0034] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
