[0023] As Figs. 1-3 The utility model discloses the specific embodiment for a kind of vertical fixed clamp specially designed for automobile PTC (Positive Temperature Coefficient, positive temperature coefficient) element glue pouring process, to ensure the high efficiency and accuracy of glue pouring operation. The following is the detailed description of the specific embodiment of the clamp:

[0024] First, prepare a workbench 1, which is installed with two parallel tracks 3 that can move horizontally left and right. These tracks 3 are automatically moved by motor or other driving mechanism, or can be designed as manual operation to adapt to different working environment needs. The clamp assembly 2 is the core part of the invention, which is installed between the two tracks 3 and can freely slide along the tracks 3. The automobile PTC workpiece is a flat plate structure with cable 42 and fixed buckle 41, which has bottom fixed buckle 41 and cable 42.

[0025] The clamp assembly 2 is composed of a base plate 21, a limiting block 22, a mounting plate 23 and a limiting plate 24. The base plate 21 is a concave-shaped structure with a first notch 211 designed for the cable 42 on the bottom of the automobile PTC workpiece to pass through smoothly while maintaining the stability of the workpiece. The two ends of the base plate 21 are movably installed on the track 3 through sliding blocks 26. The limiting block 22 is installed on both sides of the first notch 211 of the base plate 21 to preliminarily limit the position of the automobile PTC workpiece 4. The limiting block 22 is provided with a limiting groove 221 matching the width of the bottom of the workpiece to ensure that the workpiece is placed horizontally. The mounting plate 23 is vertically fixed to the side of the limiting block 22, and the top of the mounting plate 23 is provided with a concave-shaped third notch 231 to provide space for the flipping of the limiting plate 24. The limiting plate 24 is hinged to the top of the mounting plate 23 through a hinge 25, one end of the hinge 25 is fixedly connected to the mounting plate 23, and the other end is connected to the limiting plate 24 to ensure that the limiting plate 24 can be flipped flexibly and stably. The limiting plate 24 can be rotated 90° around the hinge 25, and the limiting plate 24 is provided with a concave-shaped second notch 241 matching the width of the middle part of the automobile PTC workpiece 4. When the workpiece is inserted between the limiting blocks 22, the limiting plate 24 can be flipped to further fix the middle part of the workpiece.

[0026] In order to make the clamp assembly 2 more matched with the automobile PTC workpiece, the width of the limiting groove 221 matches the width of the bottom of the automobile PTC workpiece, and the width of the second notch 241 of the limiting plate 24 matches the width of the middle part of the automobile PTC workpiece; the height difference between the bottom of the limiting groove 221 and the upper surface of the base plate 21 is greater than the protruding length of the fixed buckle 41 on the bottom of the automobile PTC workpiece; the cable 42 on the bottom of the automobile PTC workpiece can extend out of the first notch 211 of the base plate 21.

[0027] When using the vertical fixed clamp, 1, workpiece fixing: insert the automobile PTC workpiece 4 into the limiting groove 221 between the limiting blocks 22 to ensure that the protruding part of the fixed buckle 41 on the bottom of the workpiece does not interfere with the base plate 21 (because the height difference between the bottom of the limiting groove 221 and the upper surface of the base plate 21 is greater than the protruding length of the fixed buckle 41). At this time, the cable 42 on the bottom of the workpiece can extend out of the first notch 211 of the base plate 21 smoothly.

[0028] 2, flipping of the limiting plate 24: after the workpiece is preliminarily positioned, manually or by using a mechanical device to flip the limiting plate 24 by 90°, so that the second notch 241 of the limiting plate 24 closely fits the middle part of the workpiece, achieving complete fixation of the workpiece.

[0029] 3, glue pouring operation: a support frame 5 is arranged on one side of the track 3, and a glue pouring gun 6 capable of moving horizontally and adjusting the angle up and down is assembled on the support frame 5. When the clamp assembly 2 moves to the designated position along the track 3 and is locked (by the locking screw on the base plate 21 cooperating with the fixed nut on the track 3), the glue pouring gun 6 can start to accurately pour glue on the automobile PTC workpiece.

[0030] The bottom plate 21 and the mounting plate 23 in the application are preferably made of metal materials to ensure the structural strength and durability of the clamp assembly 2, and the bottom plate 21 and the mounting plate 23 can be repeatedly used to reduce the cost, wherein the limiting block 22 and the limiting plate 24 are made of replaceable elastic plastic structure to adapt to PTC workpieces of different sizes and shapes, and to reduce the damage of the clamp to the workpiece.

[0031] The inner corner of the limiting groove 221 in the application is designed as an arc fillet 222 to match the bottom arc structure of the workpiece, and the fixation is more compact, in addition, the second gap 241 of the limiting plate 24 is designed as a rectangular opening to match the middle shape of most automobile PTC workpieces.

[0032] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any slight modification, equivalent replacement and improvement of the above embodiment according to the technical essence of the present application shall be included in the protection scope of the technical scheme of the present application.
