In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0023] As the instruction manual Figure 1 As shown, the utility model provides a camera module carrier plate fixture, including a carrier plate 1, wherein the carrier plate 1 is provided with a plurality of limit grooves 11 for accommodating a camera module 2, and each limit groove 11 is arranged in a matrix, and a lens avoidance hole 12 penetrating the carrier plate 1 for a camera lens to pass through is provided at the bottom of the limit groove 11, and the end of the lens avoidance hole 12 away from the limit groove 11 is provided with a fixing unit for fixing the camera lens, and a connecting groove 13 is provided between two adjacent limit grooves 11, and the two adjacent limit grooves 11 may be between two longitudinally adjacent limit grooves 11, or between two transversely adjacent limit grooves 11, or a connecting groove 13 is provided between a limit groove 11 and the transversely and longitudinally adjacent limit grooves 11. In this embodiment, a connecting groove 13 is provided between two longitudinally adjacent limit grooves 11, and the longitudinal direction is parallel to the width direction of the carrier plate 1.

[0024] Specifically, the carrier 1 is square, and each of the limit grooves 11 is arranged in the middle of the carrier 1. The multiple limit grooves 11 are distributed in a matrix on the carrier 1, that is, the carrier 1 is laterally provided with multiple limit groove groups, and each limit groove group includes multiple limit grooves 11 arranged at intervals along the longitudinal direction, which are laterally parallel to the length direction of the carrier 1 and longitudinally parallel to the width direction of the carrier 1. The camera module 2 is placed on the limit groove 11, and the top of the lens passes through the lens avoidance hole 12 to expose the bottom of the carrier 1. The top end face of the lens is fixed by a fixing unit to avoid tilting or moving during the production process, and then the glue is applied in the equipment, that is, the IR bonding operation is performed. After the bottom of the lens cavity (that is, the end away from the lens) is glued by the crystal bonding machine, the vacuum nozzle rod of the machine absorbs the IR sheet 3 and places it in the glued area, so that the IR sheet 3 is tightly attached to the lens cavity to complete the IR bonding operation. During the operation, the camera module is fixed by the fixing unit, which can effectively avoid the camera from being offset and ensure the accuracy of glue application and IR bonding.

[0025] The size of the limiting groove 11 is adapted to the size of the camera module 2 , and a connecting groove 13 is provided between the longitudinally adjacent limiting grooves 11 , so that there is a gap between the limiting groove 11 and the camera module 2 , which is convenient for taking and placing the camera module 2 .

[0026] An optimized implementation method, wherein the fixing unit comprises an adhesive tape, wherein the adhesive tape is arranged at a position corresponding to the lens avoidance hole 12, wherein the adhesive tape is preferably a blue film adhesive tape, which can bond the camera lens without affecting the lens, and an adhesive tape is arranged corresponding to the position of each avoidance hole, for the convenience of operation and the convenience of flipping the camera after IR bonding. The adhesive tape is an integrated adhesive tape, which is bonded to the bottom of the carrier board 1, and the adhesive tape can be attached and removed as a whole, and the operation is convenient, and the adhesive surface of the adhesive tape faces the lens avoidance hole 12.

[0027] In an optimized implementation, the depth of the lens avoidance hole 12 is not less than the thickness of the camera lens, so that the lens can be exposed from the bottom of the carrier board 1 and bonded to the tape.

[0028] In an optimized implementation mode, the lateral dimension of the connecting groove 13 is smaller than the lateral dimension of the limiting groove, that is, the width of the connecting groove 13 is smaller than the width of the camera module 2, so as to prevent the camera module 2 from slipping out of the connecting groove 13. The camera module 2 can be limited in the limiting groove 13, and the lateral dimension is parallel to the length direction of the carrier plate 1.

[0029] In an optimized implementation mode, arc-shaped grooves 14 are provided on the groove walls of the limiting grooves 11 at both ends in the longitudinal direction, as shown in the attached manual. Figure 2 As shown, the arc groove 14 is arranged on the extension line of the connecting groove 13, so as to facilitate the taking and placing of the camera module 2 in the limiting grooves 11 at both ends in the longitudinal direction.

[0030] In an optimized implementation, the two longitudinal sides of the carrier plate 1 are provided with sinking parts 15 for placing the carrier plate on the device for use. The thickness of the middle of the carrier plate 1 is greater than the thickness of the sinking part 15, so that the carrier plate 1 has enough thickness to set the limit groove 11 and the lens avoidance hole 12.

[0031] Optimized implementation method: after the camera module 2 is glued and IR bonded, it is necessary to flip the camera module 2 so that the lens faces upwards to facilitate the next process. There are two carriers 1, one of which is covered on the other carrier 1, and the limit grooves 11 on the two carriers 1 are arranged one by one, as shown in the attached manual. Figure 3 As shown, they are respectively marked as the first carrier plate 1a and the second carrier plate 1b. The first carrier plate 1a and the second carrier plate 1b have the same structure, and the camera module is subjected to glue painting and IR bonding operations on the first carrier plate 1a. After completing the above operations, the second carrier plate 1b is covered on the first carrier plate 1a, and then flipped 180 degrees so that the second carrier plate 1b is at the bottom, the tape on the first carrier plate 1a is torn off, and the camera module is flipped into the limit groove of the second carrier plate 1b with the lens facing upward, so that the batch flipping of the camera module 2 can be completed.

[0032] In order to ensure the rapid positioning of the first carrier plate 1a and the second carrier plate 1b, a first positioning portion 16 is provided at one end of the carrier plate 1, and the first positioning portion 16 is a boss. The other end of the carrier plate is provided with a second positioning portion 17 which is positioned and matched with the first positioning portion 16, and the second positioning portion 17 is a through hole. When the second carrier plate 1b is covered on the first carrier plate 1a, the through hole of the second carrier plate 1b corresponds to and is positioned with the boss of the first carrier plate 1a, and the boss of the second carrier plate 1b corresponds to and is positioned with the through hole of the first carrier plate 1a, which can realize the rapid positioning of the two carrier plates, ensure the stability and accuracy of the flipping process, avoid damage to the lens, and make the already bonded camera lens face upward, waiting to enter the next process.

[0033] Preferably, the first positioning portion may be a boss or a through hole. If a plurality of first positioning portions are provided, they may all be bosses or through holes, or some may be bosses and some may be through holes. The second positioning portion is positioned and matched with the first positioning portion in a one-to-one correspondence.
