All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 2, an embodiment of the present invention provides a turntable system including a turntable mechanism 1 and at least one set of jig opening assemblies 3 provided outside the turntable mechanism 1. The top of the turntable mechanism 1 is provided with a plurality of welding jigs 2 which are circumferentially distributed, and the welding jigs 2 rotate along with the turntable mechanism 1. The welding jig 2 is provided with an elastic pressing structure and a pushing structure 24, the elastic pressing structure is used for pressing a workpiece, and the pushing structure 24 moves and is linked with the elastic pressing structure to loosen the workpiece. The jig opening assembly 3 is used for controlling the pushing structure 24 to move.

When the welding jig 2 needs to be opened to loosen the workpiece, the jig opening assembly 3 works to control the pushing structure 24 to move, and the elastic pressing structure linked with the pushing structure 24 loosens the workpiece under the linkage action, so that the welding jig 2 is opened. In this way, when the turntable mechanism 1 rotates the welding jig 2 to the station for feeding or discharging, the jig opening assembly 3 can be conveniently matched to open the welding jig 2, so that the feeding or discharging of the workpiece is facilitated.

Referring to fig. 4 to 6, the welding jig 2 includes a jig main body 21. The elastic pressing structure comprises a transverse pressing structure 22 and a longitudinal pressing structure 23 which are both arranged on the jig main body 21, wherein the transverse pressing structure 22 is used for transversely pressing a workpiece, and the longitudinal pressing structure 23 is used for longitudinally pressing the workpiece. The pushing structure 24 is arranged on the jig main body 21 in a sliding manner, and the pushing structure 24 moves and links the transverse compression structure 22 and the longitudinal compression structure 23 to synchronously loosen the workpiece. The longitudinal direction and the transverse direction are both horizontal directions.

When the pushing structure 24 moves, under the linkage action, the transverse pressing structure 22 and the longitudinal pressing structure 23 are driven to synchronously loosen the workpiece, so that the clamping of the workpiece can be simultaneously released in two directions only by the single movement action of the pushing structure 24, the opening action of the welding jig 2 is simplified, and the number of jig opening assemblies 3 is simplified.

Optionally, at least one positioning step 214 protruding upwards is formed on the jig main body 21, the positioning step 214 is used for placing a workpiece, and the positioning step 214 is matched with the transverse pressing structure 22 and the longitudinal pressing structure 23 to clamp the workpiece.

As an alternative embodiment, as shown in fig. 24 and 25, the retaining mechanism 833 includes a first plunger 8331 having an elastically stretchable end, a retaining seat 8332, a swing arm 8333, a retaining finger 8334, and a connecting shaft 8335.

The first plunger 8331 is mounted on one of the swing arm 8333 and the stopper 8332, and the other is abutted against the elastic expansion end of the first plunger 8331.

The stop finger 8334 is used to limit the movement of the strip only in the direction of the reject outfeed zone.

As a specific example, the distance from the connecting shaft 8335 to the feeding stage 8321 is smaller than the rotation radius of the stopping pawl 8334, so that the stopping pawl 8334 can limit the movement of the material belt only toward the waste discharging area, and no additional driving device is required to control the rotation of the pawl body stopping pawl 8334.

The movement of the strip from the feed station 8321 toward the reject outfeed zone is considered to be a forward movement, and vice versa.

The material belt may be provided with a positioning structure for being matched with the stop pawl 8334, for example, a plurality of third positioning holes 021 are formed on the frame 02 along the length direction, and the bottom end of the stop pawl 8334 can be inserted into the third positioning holes 021.

As an example, one end of the retaining finger 8334 is connected to the connecting shaft 8335, and the other end of the retaining finger 8334 has a tendency to rotate downward under the pulling action of the reverse movement of the material belt or the elastic action of the first plunger 8331, and the distance from the connecting shaft 8335 to the feeding table 8321 is smaller than the rotation radius of the retaining finger 8334, so that the retaining finger 8334 is blocked by the feeding table 8321 when rotating downward, and cannot rotate in a complete circumference. Based on the above structure and principle, when the material belt moves forward, the stopping finger 8334 rotates upward under the action of the material belt, allowing the material belt to pass through; when the material belt moves reversely, the stop pawl 8334 has a tendency to rotate downwards under the action of the material belt, but the stop pawl 8334 cannot rotate due to the obstruction of the feeding table 8321, so that the material belt can be prevented from moving reversely, and the stop function is realized.

Taking fig. 24 as an example, when the material belt moves reversely, the material belt pulls the stopping pawl 8334 to rotate counterclockwise in fig. 24, and when the stopping pawl 8334 rotates to the lowest position, the stopping pawl 8334 touches the feeding table 8321 or the material belt, the stopping pawl 8334 is limited by the feeding table 8321 and cannot rotate counterclockwise in fig. 24, so that the bottom end of the stopping pawl 8334 presses the material belt or passes through a positioning structure on the material belt to prevent the material belt from moving away.

The backstop finger 8334 may be bent, hooked, etc.

The first plunger 8331 is used to reset the backstop finger 8334 so that the backstop finger 8334 can better maintain the backstop function. When the material belt moves forward, under the pulling of the material belt, the bottom end of the retaining finger 8334 is lifted, the material belt is allowed to move through, the retaining finger 8334 rotates upwards to drive the connecting shaft 8335 and the swing arm 8333 to rotate, the swing arm 8333 and the retaining seat 8332 cooperate with each other to compress the first plunger 8331, the first plunger 8331 generates elastic potential energy, thrust is given to the swing arm 8333, and then the connecting shaft 8335 rotates, the retaining finger 8334 rotates downwards, and reset is achieved.

As a specific example, the distance from the finger shaft 8432 to the second loading table 841 is smaller than the rotation radius of the finger 8436, so that the finger 8436 has the function of pulling the tape in a single direction, and no additional driving device is required to control the rotation of the finger 8436.

The material belt may be provided with a positioning structure for being matched with the claw 8436, for example, a plurality of third positioning holes 021 are formed on the frame 02 along the length direction, and the bottom end of the claw 8436 can be inserted into the third positioning holes 021.
