[0027] The technical solution of the transfer fixture provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] This embodiment provides a transfer fixture, such as Figure 1 and Figure 2 As shown, the transfer fixture includes a base 1, a gripper assembly 2, a positioning assembly 3, and a drive assembly 4. The base 1 has a placement slot 111 for placing transfer products. The gripper assembly 2 is slidably connected to the base 1 and can clamp or release the transfer products. The positioning assembly 3 positions the gripper assembly 2 away from the transfer products, allowing the gripper assembly 2 to release the transfer products and facilitate placement in the placement slot 111. The drive assembly 4 drives the gripper assembly 2 to position or disengage from the positioning assembly 3, enabling the gripper assembly 2 to pick up and place the transfer products. With this structure, the transfer fixture can accurately clamp and position transfer products during the handling process, facilitating rapid pick-up and placement and precise positioning of transfer products, thus improving production efficiency.

[0029] In this embodiment, as Figure 3 As shown, the base 1 includes a seat body 11, with a placement slot 111 formed on the seat body 11, allowing the transfer product to be placed on the seat body 11. Preferably, the base 1 also includes a transfer plate 12, with the seat body 11 connected to the transfer plate 12. This transfer fixture can move between various workstations via the transfer plate 12, enabling the transfer fixture to transport the transfer product between workstations. Preferably, the transfer plate 12 is provided with a transfer positioning hole 121, and a positioning pin is provided at each workstation. The positioning pin can be inserted into the transfer positioning hole 121, so that the transfer plate 12 drives the transfer fixture to accurately stop at the designated workstation.

[0030] Preferably, the base 11 has a groove 112, and the gripper assembly 2 is slidably connected within the groove 112. Specifically, the gripper assembly 2 includes a slider 23 and a gripper body 21. The gripper body 21 is connected to the slider 23, and the slider 23 is slidably connected within the groove 112, allowing the gripper body 21 to slide smoothly relative to the groove 112. Specifically, the gripper body 21 is connected to the slider 23 by screws, making the gripper body 21 detachably connected to the slider 23, facilitating the disassembly and maintenance of the gripper assembly 2.

[0031] Further, if Figure 2As shown, the gripper assembly 2 also includes an elastic element 22. The elastic element 22 is used to drive the slider 23 to move the gripper body 21 to clamp the transferred product, and to ensure that the transferred product can be clamped by the gripper body 21 during transportation, preventing displacement and facilitating accurate positioning. Specifically, the elastic element 22 includes a spring, which is placed in the slide groove 112 and abuts against the slider 23 and the seat 11, providing sufficient force to the slider 23 to move the gripper body 21 to clamp the transferred product. In this embodiment, as... Figure 4 As shown, the slider 23 is provided with a spring positioning hole 232, and a part of the spring is located in the spring positioning hole 232, thereby positioning the spring and facilitating its installation.

[0032] It is worth noting that the gripper assembly 2 is provided with at least three sets, so that the transfer fixture includes at least three gripper bodies 21, enabling the transfer fixture to clamp the transfer product. The at least three sets of gripper assemblies 2 are evenly distributed circumferentially around the placement groove 111, so that the transfer fixture firmly clamps the transfer product.

[0033] In this embodiment, the positioning component 3 includes a ball 31 connected to the base 1. The gripper body 21 can engage with the ball 31 to release the product and maintain the open state. Preferably, as shown below... Figure 4 As shown, the slider 23 has a positioning groove 231, and the ball 31 can be engaged in the positioning groove 231, so that the ball 31 can position the slider 23 and prevent it from sliding, keeping the gripper body 21 in the open state. Specifically, the positioning component 3 also includes a mounting post 32, which is connected to the base 1, and the ball 31 is connected to the mounting post 32, so that the ball 31 is firmly installed.

[0034] In this embodiment, the driving component 4 includes an opening top block 41 and a clamping top block. The opening top block 41 can push the slider 23 away from the circulating product to engage with the ball 31. The clamping top block can push the slider 23 away from the ball 31, so that the gripper body 21 on the slider 23 can clamp the circulating product under the action of the spring. Preferably, the opening top block 41 is provided with a driving inclined surface 411, which can slide against the slider 23 to drive the slider 23 to move. Specifically, the base 1 also includes a cover plate 13, which covers the base body 11 to partially cover the slider 23 in the slide groove 112. The cover plate 13 is provided with a top block slot 131, through which the opening top block 41 can be inserted and drive the slider 23 to move.

[0035] The working process of the transfer fixture provided in this embodiment will be explained step by step below.

[0036] After the transfer fixture is in place or returned to its original position from another station, the top block 41 opens, driving the slider 23 to engage with the ball 31, keeping the gripper body 21 open. Then, the transfer product is loaded into the transfer fixture, and the clamping top block moves to push the slider 23 away from the ball 31. Under the action of the spring, the slider 23 drives the gripper body 21 to clamp the transfer product and maintain the clamped state. The transfer fixture flows into each station through the transfer plate 12. After the work of each station is completed, the transfer fixture returns to its original position.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
