Detailed Description

In order to better understand the technical solution of the present invention, the following detailed description is given by way of specific examples.

Please refer to fig. 2. Taking an example (but not limited to) that a coating fixture 20 of the present invention is applied to the key product 10 of fig. 1 requiring coating, a coating fixture 20 of the present invention may include: the body 22, the side plate 21, the fixing strip 23, and the push-pull strip 24. Wherein, the side plates 21 are installed on both sides of the body 22, and the fixing bar 23 and the push-pull bar 24 are sequentially installed on the upper end of the body 22.

Please refer to fig. 2. In a preferred embodiment, the body 22 may be elongated, for example, the body 22 may be rectangular and elongated. A groove 221 is provided in the upper surface of the rectangular body 22 along the length of the body 22. The opening of the groove 221 is disposed upward. The groove 221 may be open at both ends or closed (or closed at one end).

The fixing bar 23 may have a long bar shape corresponding to the body 22. The fixing strip 23 is overlapped on the upper ends of both sides of the groove 221 along the length direction of the body 22 (the groove 221), and is fixedly mounted with the upper ends of both sides of the groove 221 (the upper end of the body 22). For example, the fixing bar 23 may be welded to the upper end surfaces of the two sides of the groove 221 to block the opening of the groove 221 from above the groove 221.

A plurality of first fitting holes 232 arranged in the length direction of the fixing bar 23 are processed on the surface of the fixing bar 23. The first fitting hole 232 has a hole insertion portion 2321 and a hole locking portion 2322 that is smaller in opening than the hole insertion portion 2321 in communication therewith, as shown in fig. 3. The fastening hole 2322 may have a uniform transverse opening width, or one end of the fastening hole 2322 away from the insertion hole 2321 may have a transverse opening width slightly larger than the other end of the fastening hole 2321 close to the insertion hole 2321, so that a waist-shaped section with a contracted opening is formed at a transition region between the insertion hole 2321 and the fastening hole 2322.

The first assembling holes 232 on the fixing bar 23 are oriented in the same direction, that is, the fastening hole 2322 of each first assembling hole 232 on the fixing bar 23 is uniformly disposed toward the same end of the body 22 (the groove 221).

The first fitting hole 232 may be designed in an axisymmetrical structure. At this time, the center line (axis) of each first fitting hole 232 coincides with the center line direction of the groove 221. Further, the center lines of the first fitting holes 232 of the fixing bar 23 coincide with each other and with the center line of the groove 221.

In a preferred embodiment, the insertion hole portions 2321 on the first assembly holes 232 have a diameter (caliber) significantly larger than that of the pins (assembly portions) 12 of the key product 10, i.e., the insertion hole portions 2321 are not used for cooperating with the pins 12, but serve to allow the pins 12 to be smoothly received into the insertion hole portions 2321. In other words, the shape of the socket portion 2321 need not conform to the pin 12 (i.e., may not be limited to a circular shape) as long as the pin 12 can be smoothly inserted. The feature of the ring groove 13 on the pin 12 can be utilized to design the opening of the hole-fastening portion 2322 to be capable of fitting with the diameter of the ring groove 13 (fastening position) in a clearance manner, but smaller than the width of the other side portion of the pin 12 except the ring groove 13. Meanwhile, the thickness of the fixing bar 23 is designed to be smaller than the opening height of the ring groove 13.

Please refer to fig. 2. The push-pull strip 24 may likewise be elongated corresponding to the body 22 and disposed over the fixed strip 23. Meanwhile, the push-pull strip 24 is arranged to move lengthwise on both upper ends of the groove 221, i.e., the push-pull strip 24 can move lengthwise in translation relative to the fixed strip 23.

In an alternative embodiment, to enable the push-pull strip 24 to translate across the groove 221, a catch may be provided on the upper end of the groove 221, with the push-pull strip 24 fitting into the catch to translate along the catch relative to the underlying fixed strip 23.

In an alternative embodiment, the body 22 may be assembled to form a slot structure. For example, the upper end (in the longitudinal direction) of each side plate 21 may be bent by a pair of side plates 21 disposed separately from the body 22, so that one bent portion 211 is formed at the upper end portion of each side plate 21. Preferably, the bending angle of the bending portion 211 may be a right angle or a nearly right angle.

The two side plates 21 are connected to the two side surfaces of the body 22 in the direction opposite to the bent portions 211, and for example, the side plates 21 and the body 22 may be fixed by welding. Moreover, a certain distance is left between the bending part 211 at the upper end of the side plate 21 and the upper end surface of the groove 221, so that a pair of clamping grooves are formed on the upper end surfaces at two sides of the groove 221. The upper end surface of the groove 221 may be used as the groove bottom of the clamping groove, or the upper surface of the fixing plate may be used as the groove bottom of the clamping groove, and the inner side of the bent portion 211 of the side plate 21 may be used as the groove top of the clamping groove.

The assembly structure of the body 22 with the side plate 21 and the slot is shown in fig. 4.

The push-pull strip 24 is horizontally inserted into the slot along one end of the slot, and then can move relatively on the fixing strip 23.

A plurality of second fitting holes 242 arranged in the length direction are provided on the surface of the push-pull strip 24. The distance between two adjacent second assembling holes 242 is equal to the distance between the inserting hole portions 2321 or the distance between the clamping hole portions 2322 of two adjacent first assembling holes 232 at the corresponding positions of the lower fixing strip 23.

When the product 10 is provided with a pair of pins 12 as shown in fig. 1, for example, the second fitting holes 242 are also correspondingly provided in pairs on the push-pull strip 24, and the first fitting holes 232 are also correspondingly provided in pairs on the fixing strip 23, so that a plurality of products, for example, 8 products 10, can be simultaneously mounted on one jig according to design capability, as shown in fig. 2.

By utilizing the above-mentioned characteristic of the hole pattern of the first fitting hole 232 of the fixing bar 23, the product 10 can be mounted by the relative movement of the product 10 when being mounted and clamped in cooperation with the second fitting hole 242 of the push-pull bar 24.

For example, during clamping, the push-pull strip 24 is moved (pushed or pulled along the slot) such that each second fitting hole 242 of the push-pull strip 24 is aligned with the insertion hole 2321 of a corresponding first fitting hole 232 of the lower fixing strip 23 (defining that the push-pull strip 24 is located at the first position). Then, by pre-arranging a plurality of products 10 (for example, 8 products 10 are arranged end to end in a tray with pins 12 facing upwards), and using the coating jig 20 of the present invention, the second assembly holes 242 are inserted into the corresponding pins 12 of the products 10 in alignment, so that the ring grooves 13 on the pins 12 are exactly aligned with the first assembly holes 232, thereby achieving the simultaneous installation of 8 products 10 on the coating jig 20. Next, by moving the push-pull bar 24 in the reverse direction (pulling or pushing along the card slot), the pins 12 of the 8 products 10 that have been placed on the push-pull bar 24 are translated along with the push-pull bar 24 from the receptacle portions 2321 of the first assembly holes 232 into the card slot portions 2322 (defining that the push-pull bar 24 is in the second position at this time). In this state, the hole-locking portion 2322 is in clearance-locked engagement with the annular groove 13 of the pin 12 of the product 10, so that the product 10 is limited on the plane position of the fixing strip 23 and cannot move up and down obviously; moreover, the pins 12 of the product 10 are restrained by the push-pull strip 24 at the second position, so that the product 10 is kept on the coating jig 20 without falling off.

Please refer to fig. 2. In order to ensure that the push-pull bar 24 is accurately positioned in the first position and the second position due to being pushed and pulled, so that the second assembly hole 242 of the push-pull bar 24 is aligned with the insertion hole 2321 of a corresponding one of the first assembly holes 232 of the lower fixing bar 23, or is moved to be aligned with the blocking hole 2322 of the first assembly hole 232, a limit structure may be provided to limit the moving distance of the push-pull bar 24 between the first position and the second position.

In an alternative embodiment, the stop may include a first stop surface 231 disposed in the groove 221 for defining the first position and a second stop surface for defining the second position, and a stop 241 protruding above the bottom surface of the push-pull strip 24 and cooperatively received between the first stop surface 231 and the second stop surface.

In a preferred embodiment, the limit may be disposed at a first end (defined as the right end in the figure) of the groove 221, and an end surface of the fixing strip 23 corresponding to one end is used as the first blocking surface 231; at the same time, the first end of the groove 221 is machined to be a blind end (not shown) confined within the body 22, so that the inner wall of the blind end can serve as a second stop surface. The stopper 241 is provided at an end portion of the corresponding end of the push-pull bar 24 to protrude downward such that a lower end of the stopper 241 is received between an end surface of the corresponding end of the fixing bar 23 and a blind end of the groove 221.

As an example, an end surface of the fixing bar 23 corresponding to one end may be provided in a fork shape, and a bottom surface of the fork end surface may be used as the first blocking surface 231.

Please refer to fig. 2. In a preferred embodiment, to increase the strength of the sheet-shaped push-pull strip 24, the push-pull strip 24 may be provided as a double-layered push-pull strip 24 structure that is stacked and fixed (e.g., welded) together. Also, the thickness of one push-pull strip 24 located at the upper layer may be set to be greater than the thickness of one push-pull strip 24 located at the lower layer.

Further, the width of one push-pull strip 24 located on the upper layer may also be set smaller than the width of one push-pull strip 24 located on the lower layer. Such a configuration can satisfy the rigidity requirement of the push-pull strip 24, and on the other hand, only one push-pull strip 24 with relatively thin thickness located at the lower layer can be independently matched with the clamping groove formed between the bending part 211 of the side plate 21 and the fixing plate, so that the upper surface of the bending part 211 of the side plate 21 is not higher than the upper surface of one push-pull strip 24 located at the upper layer, which is beneficial to enlarging the sputtering coating direction.

Please refer to fig. 2. In other preferred embodiments, a pull 243 may also be provided on the push-pull strip 24. For example, the pull 243 may be provided on an end of the other end (defined as the left end as illustrated) of the push-pull strip 24 corresponding to the second end of the groove 221. As an example, the pull tab 243 may be provided as a laterally protruding T-shaped pull tab 243.

Referring to fig. 5 and 6, the push-pull strip 24 of the present invention is shown in use in a first position and a second position, respectively. When the push-pull bar 24 is in the first position due to being pulled, the stopper 241 is just stopped by the bottom surface of the fork at the end of the fixing bar 23 to be limited, and the lower ends of the prongs 12 of the product 10 received in the pair of second fitting holes 242 of the push-pull bar 24 are just positioned in the insertion hole portions 2321 of the first fitting holes 232 of the fixing bar 23. At this time, the distance between the pull tab 243 of the push-pull bar 24 and the end surface of the corresponding end of the body 22 is L1.

When the push-pull bar 24 is pushed to the second position, the stopper 241 is stopped by the inner side of the blind end of the groove 221 of the body 22, and the lower end of the pin 12 of the product 10 is translated to be positioned in the catch hole 2322 of the first assembly hole 232. At this time, the distance between the tab 243 of the push-pull bar 24 and the end surface of the corresponding end of the main body 22 is changed to L2. It can be seen that L2 > L1, the difference being exactly the distance traveled by the push-pull strip 24 between the first and second positions.

When the film coating jig is used for clamping products, the process of simultaneously clamping a plurality of products can be finished only by pushing the push-pull strip once, so that the efficiency is effectively improved, and the film coating jig has a wide application prospect.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that the changes and modifications of the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
